Description

Suction cap of liquid container and liquid container

The present invention relates to a suction cap of a liquid container and a liquid container, and more particularly, to a suction cap of a liquid container and a liquid container with an enhanced effect on convenience and airtightness of liquid discharge.

Normally, the liquid container is processed into glass or synthetic resin in a cylindrical shape, and one side of the liquid container is narrowed so that it can be opened and closed by a lid to store liquid materials such as beverages as contents, and to withdraw the liquid as necessary. Transparent or opaque glass bottles or plastic bottles are used depending on the type of liquid stored inside.

In particular, when the liquid as the contents can be denatured or deteriorated by light, in particular, sunlight, such as beer or fermented milk, colored bottles may be mainly used to block sunlight or ultraviolet rays, and the like, such as soft drinks. In the case of not being greatly affected by the light rays of the general transparent synthetic resin container is used.

Such a liquid container is generally composed of a body containing a liquid, and a cap (cap) for opening and closing the inside of the body by screwing to one end of the body.

In order to discharge the liquid phase of the liquid container having such a configuration it is possible to discharge the liquid by rotating the lid to open one end of the body and then freely drop the liquid by gravity by lifting the liquid container.

However, when the liquid container is used as a beverage container and consumes a beverage contained in the container, the drink may be suddenly discharged due to carelessness of the user, especially an infant or a child, and the liquid may be poured onto the clothes. There was.

Accordingly, in the case of an infant or a child, it is necessary to consume a drink using a straw whenever possible.

In particular, even in the case of adults, not infants or children, it was not easy to drink a patient lying in the bed.

Even in this case, it was very inconvenient to use the straw or to raise the torso of the patient and then consume the drink.

Of course, in order to prevent such a problem, a beverage container to which the push-pull cap is applied as shown in FIG. 1 is commercially available.

Such push-pull cap 10 can prevent the liquid from coming out suddenly, and can be inhaled by inhaling the mouth without the need to use a straw, so that infants or children can safely drink. .

However, the push-pull cap 10 type beverage container also had the following problems.

First, in order to consume a drink, always caused the inconvenience of having to drink and drink beverage containers.

In other words, the liquid container can not drink through the inhalation of the beverage container, the liquid must drop upside down to discharge the beverage container is inconvenient to drink intake.

Of course, even in the state of the beverage container, the beverage is discharged when a strong suction force is generated, but this intake is a problem that it is difficult to consume the beverage as the beverage is ingested because the liquid level in the container is lower as the beverage is ingested .

Second, there was an inconvenience to close the push-pull cap 10 after ingesting the drink.

That is, in order to stop the drink intake, the push-pull cap 10 should be closed, but if the push-pull cap 10 is open, there is a problem that the liquid drink leaks through the push-pull cap 10.

Third, since it is practically difficult to clean and used for one-time use, there was a problem of low economic efficiency.

Fourth, because the confidentiality is not maximized, the beverage can easily rot and there was a problem that the persistence of the thermal insulation is difficult to maintain.

Fifth, the liquid container provided with a cap of the push-pull type had a disadvantage that can not store the carbonated beverages such as cola.

That is, in the case of a beverage containing a foaming gas such as carbon dioxide, such as a soft drink, there is a possibility that the push-pull type cap is automatically opened by the carbonic acid pressure of the foaming gas, so that the carbonated beverage could not be stored.

In particular, the solubility of the foam gas in the beverage can be greatly influenced by the pressure and temperature, because the beverage containers containing the foam gas is supplied by packaging the beverage without a separate airtight device, the beverage container is opened, Within a short time, you can not feel any change in taste, but as time elapses, the foaming gas gradually evaporates into the air layer in the container and escapes from the drink. .

The present invention has been made to solve the above problems, an object of the present invention is to provide a liquid container to maximize the airtight maintenance, and to facilitate the liquid discharge.

Another object of the present invention is to provide a suction cap of a liquid container that can prevent foreign matter easily enters into the liquid container or leaks the liquid easily from the liquid container.

In order to achieve the above object, the present invention, the valve hole for passing through the inside, the outside is formed, the case forming a discharge pipe for discharging the liquid; fixed to the inner surface of the case, the liquid is accommodated but shrinkable material The liquid bag: to provide a liquid container comprising a.

On the other hand, as another example for achieving the above object, a valve hole for passing through the inside, the outside is formed, the case is formed with an opening for filling the liquid; Desorption in the opening of the case, the discharge pipe path that the liquid of the case is discharged Suction stopper to form; is provided along the inner circumferential surface of the case by a change in the pressure inside the case through the suction stopper, to provide a liquid container comprising a hermetic holding member for maintaining the airtight on the inner circumferential surface of the case.

On the other hand, as another example for achieving the above object, in the suction cap of the liquid container is coupled to the discharge pipe of the liquid container to control the liquid inlet and discharge into the liquid container, it is coupled to the discharge pipe, A soft discharge member having an incision formed to open and close the inside and the outside of the liquid container while being opened or restored according to the internal pressure of the container; supported by the bottom surface of the discharge member of the discharge pipe so that the cutout of the discharge member opens only above the discharge pipe And, it provides a suction cap of the liquid container consisting of: a support member for forming a space partitioned so that the liquid in the discharge pipe can enter and exit.

The liquid container according to the present invention has the following effects.

First, even if the container is not used upside down, there is an effect that the liquid phase can be discharged.

In other words, when a liquid container is used as a beverage container, it is possible to drink a liquid drink by inhaling the suction cap even when the container is upright, so that it is possible to conveniently provide a drink for a patient or an infant. When used, the liquid can be discharged by pressing the container to control the internal pressure.

Therefore, there is a high effect on the convenience of liquid discharge.

Second, the case is provided separately from the lower case and the upper case, it is possible to easily open the inside of the container.

Accordingly, since the inside of the container can be conveniently washed, the use of the container is not limited to a one-time use but can be used for various purposes, thereby having a high economic effect.

Third, because it can increase the airtight retention, it is possible to delay the decay by preventing the liquid phase from being easily deteriorated, there is an effect that can increase the persistence of the heat retention and cold storage.

That is, the material of the discharge member is made of silicon, the incision is to increase the airtight effect of the inside of the container, the discharge member can not only prevent the leakage of the liquid phase but also can enhance the airtight retention effect.

In particular, when the liquid container is used as a milk container providing a case made of a single piece of paper, it is possible to increase the shelf life and shelf life, thereby increasing the economics.

Fourth, the suction cap is configured to include a discharge member made of a silicon material to form the incision, so that the incision is opened or restored according to the pressure inside the container can be prevented from leaking the liquid.

In other words, even if the container is collapsed in the state that the outer cap is not closed, the incision is closed the discharge pipe, so there is no fear of liquid leakage, it is possible to increase the convenience for storage and use.

Fifth, since the long groove is formed in the liquid bag, the residual water can be easily discharged through the long groove even if the liquid bag is in close contact with the inner surface of the case.

Therefore, there is an effect that can facilitate the liquid discharge through the liquid container.

The terms or words used in this specification and claims are not to be construed as limiting in their usual or dictionary meanings, and the inventors may properly define the concept of terms in order to best explain their invention in the best way possible. It should be interpreted as meaning and concept corresponding to the technical idea of the present invention.

Hereinafter, a liquid container according to a first embodiment of the present invention will be described with reference to FIGS. 2 to 17C.

The liquid container has a technical feature to prevent the liquid from leaking or the liquid flow back to the inside by increasing the convenience for liquid discharge and increase the airtightness.

In addition, when the carbonated liquid is contained in the liquid container, there is a technical feature that can delay the change of the natural taste of the liquid by suppressing the opening of the container due to the carbonic acid pressure.

Accordingly, when the liquid container is used as a beverage container, it is possible to increase the convenience for drink intake to the patient or infant.

2 and 3, the liquid container includes a case, a liquid bag 300, a suction cap 400, a check valve 500, and a removable means 600.

The case constitutes an inner space, and may be formed integrally or separately provided as upper and lower parts as shown in FIG. 2.

In the present invention, but not limited to the case shape, it will be described with an example that is provided separately to the lower case 100 and the upper case 200 to facilitate washing.

The lower case 100 constitutes a lower portion of the liquid container, and forms an inner space in which the liquid bag 300 may be disposed.

The shape and material of the lower case 100 are not limited, and the valve case 110 is formed in the lower case 100.

The valve hole 110 is a passage through which a check valve into which outside air flows into the case is installed, and a position thereof in the lower case 100 is not limited.

However, the valve hole 110 is formed to penetrate the inside and the outside of the lower case 100, it may be located only below the upper end of the liquid bag to be described later.

Next, the upper case 200 constitutes an upper portion of the liquid container, and forms a discharge pipe path 210 through which the liquid is discharged.

The upper part of the upper case 200 constitutes a neck portion 220 smaller than the diameter of the upper case so that the discharge of the liquid can be effectively made, the discharge pipe 210 constitutes the inside of the neck portion 220.

The upper case 200 also forms an inner space for accommodating the liquid phase, and preferably has a shape corresponding to the lower case 100.

Next, the liquid bag 300 is a configuration that the liquid is accommodated, its volume is preferably corresponding to the volume of the lower case (100).

The upper end of the liquid bag 300 is fixed to the upper portion of the lower case 100, which is fixed to the middle of the liquid container when viewed as a whole liquid container.

At this time, even if the liquid bag 300 is fixed in the middle of the liquid container, the liquid is not contained only in the liquid bag 300, but is accommodated in the inner space of the liquid bag 300 and the upper case 200.

On the other hand, the material of the liquid bag 300 is preferably made of a soft, it may be provided as any one of the material of silicon, urethane, vinyl.

As such, the liquid is not directly contained in the case container, but by being contained in a separate liquid bag 300 having excellent shrinkage force, when the liquid is provided as a beverage, the liquid inhalation can be effectively made.

That is, when the drink is ingested, it is possible to inhale the drink even when the container is upright, rather than inverting the container.

Next, the suction cap 400 is configured to discharge the liquid through the discharge pipe 210 to the outside, it is coupled to the neck portion 220 of the upper case 200.

Suction cap 400 serves as a kind of plug to shield the discharge pipe 210, and includes a discharge member 410 made of a soft material.

In this case, the material of the discharge member 410 is most preferably silicon.

On the other hand, the discharge member 410 forms a cutout 411 so that the liquid discharge can be effectively controlled.

At this time, the shape of the cutout 411 is preferably in the form of a date (一字) or cut in several directions.

That is, the discharge of the liquid is made through the incision 411, usually in the incision 411 is a state in which the liquid is always in the state of maintaining the airtight because the container is closed by closing the discharge passage 210 due to the characteristics of the material ( Leaving through 411 does not occur.

When inhalation force is generated in the suction cap 400 or the case is pressed to artificially increase the internal pressure for the beverage intake, the incision 411 of the discharge member 410 is opened upward while opening the discharge pipe 210 to open the liquid phase. This can be discharged.

Thereafter, the incision 411, which was opened when the drink is stopped, is restored to close the discharge pipe 210 to maintain the airtightness.

On the other hand, the support member 420 is preferably further disposed on the bottom of the discharge member 410.

The supporting member 420 is to prevent the liquid or foreign matter from flowing back into the case by making the cutout 411 open only on one side, that is, above the discharge pipe 210.

That is, as the support member 420 is disposed on the bottom surface of the discharge member 410, the cutout 411 interferes with the support member 420 to be constrained downwardly, that is, toward the inside of the container, and thus the cutout 411 is provided. ) Always opens toward the upper side of the discharge pipe 210, the liquid is discharged from the inside of the case, the foreign matter is not introduced into the inside of the case.

At this time, the support member 420 is formed in a form corresponding to the bottom surface of the discharge member 410, it is divided into a plurality as shown in Figure 2 so that the liquid discharge can be made smoothly while supporting the cutout 411 Form a space.

At this time, it is preferable that the form constituting the partitioned space corresponds to the cut-out form of the cutout 411.

Next, the check valve 500 is discharged from the liquid phase of the liquid bag 300 when the liquid bag 300 is contracted in the lower case 100, so that the outside air flows from the lower inside the lower case 100 It serves to support the liquid bag 300 in a contracted state.

The check valve 500 is installed below the lower case 100 and may be provided in various configurations.

As illustrated in FIG. 2, the check valve 500 includes a pair of vinyls 510 and a bending member 520.

Vinyl 510 is overlapped with each other, but close to each other, both sides are configured to allow air to flow between a pair of vinyl 510.

At this time, the through hole 511 is formed in any one vinyl 510 of the pair of vinyl 510.

At this time, any one vinyl 510 is a vinyl facing the bottom of the lower case 100, the through hole 511 corresponds to the valve hole (110).

That is, the outside air introduced through the valve hole 110 flows in between the pair of vinyls 510 through the through hole 511 and then into the inner space of the lower case 100 through both open sides of the vinyl 510. It can be introduced.

At this time, between the through hole 511 and the valve hole 110 may be provided with a guide pipe (G) for guiding the flow of air.

In addition, the folding member 520 plays a role of effectively restoring between the pair of vinyls 510 while the outside air passes between the pairs of vinyls 510.

The bending member 520 is made of a flexible material, and as shown in FIGS. 2 and 3, by bending both ends of the vinyl 510 upward, adhesion between the pair of vinyls 510 is increased.

The bending member 520 is formed in a form in which both sides are bent obliquely, and is attached to both ends of the bottom surface of the vinyl 510 or both ends of the top surface of the vinyl 510, respectively.

On the other hand, as described above, it is important that the pair of vinyls 510 is closely contacted with each other so that the air of the lower case 100 does not leak again while the vinyl 510 is opened in the process of passing outside air. In addition to 520, an adhesive may be provided between the pair of vinyls 510.

In this case, the pressure-sensitive adhesive does not mean to provide a strong adhesive force, but refers to a pressure-sensitive adhesive that is relatively weak as applied to a memo paper commonly called a post-it.

Next, the detaching means 600 serves to detach the lower case 100 and the upper case 200, it is installed in the lower case 100 and the upper case 200.

The detachable means 600 includes a groove 610, a fixing protrusion 620, and a closing cover 630.

The groove 610 is a configuration in which the fixing protrusion 620 is coupled, and is formed in any one of the lower case 100 and the upper case 200.

Of course, the groove 610 may be formed in each of the lower case 100 and the upper case 200, which will be described later as another embodiment of the present invention.

For convenience of description, in the first embodiment of the present specification, the groove 610 is formed in the upper case 200 as an example.

The groove 610 includes a guide groove 611 and a locking groove 612.

The guide groove 611 serves to guide the fixing protrusion 620 to be inserted into the locking groove 612 and is opened in the height direction of the upper case 200 from the edge of the end.

The locking groove 612 is a configuration in which the fixing protrusion 620 is hooked and coupled to the locking groove 612 to restrain the upper case 200 from moving upward from the lower case 100.

The locking groove 612 is formed along the circumferential surface of the upper case 200 from the guide groove 611.

In addition, the fixing protrusion 620 is configured to be hooked to the engaging groove 612, is formed on the upper peripheral surface of the lower case (100).

The fixing protrusion 620 includes a first fixing protrusion 621 that is caught and coupled to the locking groove 612, and a second fixing protrusion 622 that is caught and coupled to the closing cover 630.

The first fixing protrusion 621 is configured to be positioned at the end of the locking groove 612, the second fixing protrusion 622 is formed spaced apart from the first fixing protrusion 621.

And, the closing cover 630 is to prevent the first fixing protrusion 621 caught in the locking groove 612 is separated, and serves to restrain the rotation of the upper case 200.

That is, if the first fixing protrusion 621 and the locking groove 612 restrains the upward departure of the upper case 200, the second fixing protrusion 622 and the closing cover 630, the upper case 200 is rotated It is to restrain the first fixing projections 621 from being separated.

The closing cover 630 has a fixing groove 631 and the restraining member 632 is formed.

The fixing groove 631 is configured to prevent the closing cover 630 from being caught by the second fixing protrusion 622, and one side of the fixing groove 631 corresponds to the second fixing protrusion 622 and has a fixing groove ( The other side of 631 is formed to have a larger width than the second fixing protrusion 622.

The reason why the width of one side and the other side of the fixing groove 631 is different, so that the second fixing protrusion 622 is guided through the other side of the fixing groove 631 in the process of being fixed to one side of the fixing groove 631. To do this.

At this time, one side of the fixing groove 631 is connected to the square groove, the first fixing protrusion 621 and the second fixing protrusion 622 corresponding to the second fixing protrusion 622 as shown in FIG. A circular groove corresponding to the member is formed in multiple stages.

The restraining member 632 is disposed in the guide groove 611 to restrain the rotation of the upper case 200, and protrudes from the one end of the closing cover 630 by the depth of the guide groove 611.

Hereinafter, the coupling and action of the liquid container having the above configuration will be described.

The check valve 500 is coupled to the valve hole 110 of the lower case 100.

In this case, the through hole 511 corresponds to the valve hole 110, and both ends of the vinyl 510 are disposed in the lower case 100.

Next, the liquid bag 300 is fixed to the upper end of the lower case 100 in an open state.

Next, the upper case 200 is coupled to the lower case 100 to be coupled.

At this time, the upper case 200 is fixed so as not to be separated using the detaching means 600, which will be described with reference to FIGS. 4A to 4E.

As shown in FIGS. 4A and 4B, the upper case 200 is covered with the lower case 100 so that the first fixing protrusion 621 is inserted into the guide groove 611.

Thereafter, when the upper case 200 is rotated, as shown in FIG. 4C, the first fixing protrusion 621 is positioned at the end of the locking groove 612.

Accordingly, the upper case 200 is constrained to be separated from the lower case 100 upward.

Next, as shown in FIG. 4D, the second fixing protrusion 622 is inserted into the fixing groove 631 of the closing cover 630.

Next, when the finishing cover 630 is pushed to the left in the drawing, the second fixing protrusion 622 is located in a square groove formed on one side of the fixing groove 631, the first fixing protrusion 621 and The member connecting the second fixing protrusion 622 is located in a circular groove.

In addition, the restraining member 632 is located in the guide groove 611 as shown in FIG. 4E, so that the closing cover 630 is not separated from the second fixing protrusion 622.

Thus, the coupling of the upper case 200 and the lower case 100 is completed.

Next, the liquid is contained in the case through the discharge pipe (210).

At this time, the liquid is not only contained in the liquid bag 300, it is in the state up to the upper case 200.

The liquid may be a beverage in general, but may be used as a detergent container containing a liquid detergent.

On the other hand, when the beverage liquid is contained, the suction cap 400 is coupled to the neck portion 220 of the upper case 200.

At this time, the discharge member 410 is coupled to the inside of the suction cap 400, and the support member 420 is coupled to the bottom of the discharge member 410.

Afterwards, the suction cap 400 is covered with an outer lid to finish.

In this state, if you want to drink the beverage, as shown in Figure 5a, after the outer lid is flipped, the suction cap 400 to generate a suction force or press the case (100,200) outside the pressure change inside the case In this case, the cutout 411 of the discharge member 410 is opened upward, and the liquid is discharged to the outside through the opened cutout 411.

At this time, as the liquid contained in the liquid bag 300 exits a predetermined amount, the liquid bag 300 is contracted as shown in FIG. 5A.

At this time, in the process of shrinking the liquid bag 300, the outside air due to the pressure difference between the inside and the outside of the lower case 100 through the valve hole 110 and the check valve 500 the inner space of the lower case 100 Inflow to

That is, the outside air flows into the through hole 511 of the vinyl 510 through the valve hole 110, and then exits into the lower case 100 through the open portions of both ends of the vinyl.

At this time, the bending member 520 attached to the bottom surface of the vinyl 510 by the pressure of the outside air is unfolded as shown in Figure 5a.

On the other hand, when the drink intake is stopped, the cutout 411 of the discharge member 410 is restored to close the discharge pipe 210 again.

At this time, since the cutout 411 interferes with the support member 420 below, the opening 411 does not occur downward.

As the cutout 411 is restored in this manner, as shown in FIG. 5B, the inside of the case is kept airtight again, and the opened pair of vinyls 510 of the check valve 500 is brought into close contact with each other.

At this time, since the folded member 520 is bent to both ends of the vinyl 510 while being restored to its original state, the adhesion of the vinyl 510 may be effective.

Since, the inflow of outside air is blocked, since the air introduced into the lower case 100 supports the contracted liquid bag 300, even if the drink intake is stopped, the liquid bag 300 is not struck downward. do.

As such, the liquid bag 300 is maintained in a contracted state from below to upward, the level of the liquid is increased to close to the intake cap 400, bar inhalation of the beverage can be further facilitated intake of the drink of the infant or patient Can be easily made.

On the other hand, after ingesting the drink, when the liquid needs to be replenished, the suction cap 400 can be opened to replenish the liquid, since the liquid bag 300 is contracted in the space inside the case, the liquid bag 300 is restored to its original state. You have to.

To this end, the air inside the lower case 100 should be discharged. In the case of the check valve 500 made of vinyl 510, it may not be easy to discharge the air inside the lower case 100.

Accordingly, a check valve serving as the check valve 500 may be provided so that the air can be artificially discharged, and briefly with reference to FIGS. 6 to 16 attached to various embodiments of the check valve. Let's take a look.

The check valve 500 shown in FIG. 6 includes a shield 530 shielding the valve hole 110, a coupling part 540 coupled to a bottom surface of the lower case 100, and a shield 530. And a connection part 550 for connecting the coupling part 540.

The check valve 500 of this configuration should be made of a soft material such as silicon so that the inflow of outside air can be made smoothly.

Shield 530 is made of a circular shape having a diameter larger than the diameter of the valve hole 110, the coupling portion 540 is fixed to the bottom surface of the lower case (100).

The connection part 550 integrally connects the shielding part 530 and the coupling part 540, and forms a plurality of spaces between the shielding part 530 and the coupling part 540.

At this time, it is preferable that a relatively hard hard member 531 is further fixed to the upper surface of the shield 530.

This means that even when the user artificially presses the shield 530 to open the valve hole 110, the shield 530 is lifted upwards to easily open the valve ball even when the shield 530 is pressed relatively lightly. To do this.

When the check valve 500 of such a configuration is also in the process of shrinking the liquid bag 300 by the suction pressure, the shield 530 opens the valve hole 110 to allow the outside air to flow in, and the suction pressure is stopped. In the shield 530 is restored to close the valve hole (110).

On the other hand, in order to replenish the liquid, in order to restore the contracted liquid bag 300, the air inside the lower case 100 should be discharged, the lower case 100 and the upper case by releasing the detachable means 600 ( There is also a method of separating the 200, but this may cause a hassle, so if you push the shield 530 of the check valve 500 through the valve hole 110, the valve hole 110 is opened to facilitate the air discharge. It can be done.

At this time, the shield 530 may be pushed up using a tool, but it may be convenient to use a finger.

Thereafter, when the finger is released, since the shield 530 is in the original position and closes the valve hole 110, a series of procedures for replenishing the liquid may be performed.

In addition, the check valve 500 illustrated in FIG. 7 may include a soft discharge member 410 and a support member 420.

At this time, the thickness of the discharge member 410 is preferably formed relatively thin. This is to open the cutout 411 smoothly in the process of opening the cutout 411 described later.

At this time, the discharge member 410 and the support member 420 is the same as the components constituting the suction cap 400, it is also installed in the valve hole 110 may serve as a check valve 500.

That is, when pressure is generated in the cases 100 and 200, the cutout 411 of the discharge member 410 is opened upward by the outside air pressure flowing toward the valve hole 110, and the cutout 411 is opened. Through the outside air is introduced to support the contracted liquid bag 300.

Subsequently, when the internal pressure of the cases 100 and 200 is stopped, the cutout portion 411 that is opened upward is restored, but since the lower support member 420 interferes, the cutout portion 411 does not open downward.

And, the check valve 500 may be installed on one side of the lower case 100 as shown in FIG.
