Description

The present invention relates to a measuring cap that dispenses a predetermined amount of the contents of a container, and a container with a measuring cap that is equipped with the measuring cap.

The amount of seasonings, bath additives, laundry detergent, cosmetics, etc. that is used per use is usually fixed. For this reason, when a user takes out a seasoning, bath additive, laundry detergent, cosmetics, etc. (hereinafter, "contents") stored in a container from the container, the user must separately measure the amount of the content to be used per use (predetermined amount). To eliminate the need for this measurement, it is preferable that the container or a cap attached to the container has a function of taking out only the predetermined amount of the content.

As a cap having the above-mentioned function, that is, a measuring cap, Patent Document 1 proposes one that includes a supply part (liquid suction tube 8) that sucks up the contents (liquid) from a container (bottle 16) using a liquid delivery pipe 11, and a measuring tube (measuring cup 10) that stores a predetermined amount of the contents (liquid) from a passage port (liquid discharge port 9) formed in the supply part (liquid suction tube 8).

However, the contents (liquid) discharged from the passage (liquid discharge port 9) may hit the measuring tube (measuring cup 10) with force, causing it to splash and soil the surrounding area.

Patent Document 2 proposes a measuring cap that prevents scattering by forming a passage port (discharge port 36) with a specified aspect ratio.

Utility Model Registration No. 3033394 Patent No. 6411307

Incidentally, the measuring cap described in Patent Document 2 has a passage opening (discharge opening 36) with a predetermined aspect ratio, so that the direction of the contents (liquid material) discharged from the passage opening (discharge opening 36) is kept as low as possible. For this reason, if the top end of the measuring tube (measuring chamber) is low, the discharged contents (liquid material) will splash outside the measuring tube (measuring chamber).

For this reason, neither of the measuring caps described in Patent Documents 1 and 2 prevents the contents from scattering.

Therefore, the present invention aims to provide a measuring cap that can prevent the contents from scattering, and a container with a measuring cap that is equipped with the measuring cap.

In order to solve the above problems, a measuring cap according to a first aspect of the present invention includes an attachment part that is attached to a container;
a supply section to which the contents are supplied from a container via the attachment section;
a measuring cylinder in which a predetermined amount of the contents from the passage port formed in the supply section is stored,
The supply unit is located inside the measuring tube,
The supply unit is
a nozzle rising from the bottom surface of the measuring cylinder;
a nozzle plate facing the passage opening and positioned between the passage opening and the measuring cylinder ;
the nozzle plate of the supply section has a shape extending over the entire circumference, faces the passage port on the inside, and faces the measuring cylinder over the entire circumference on the outside;
a lower end of the nozzle plate connected to a tip of the nozzle;
The upper end of the nozzle plate reaches above the passage port .

Furthermore, a container with a measuring cap according to a second aspect of the present invention comprises the measuring cap according to the first aspect of the present invention,
a container to which the measuring cap attachment portion is attached;
the measuring cap and container are a spout and a pouch, respectively;
The supply portion of the measuring cap has one passage opening formed therein.

The measuring cap and the measuring capped container equipped with the measuring cap can prevent the contents from scattering when discharged from the passage opening by the nozzle plate facing the passage opening.

[Embodiment 1]

The measuring cap and the measuring cap-equipped container equipped with the measuring cap according to the first embodiment of the present invention will be described below with reference to FIG. 1.

As shown in FIG. 1, the measuring cap 1 according to the first embodiment includes an attachment part 10 that is attached to a container 100, a supply part 30 to which the contents L are supplied from the container 100 via the attachment part 10, and a measuring tube 40 in which a predetermined amount of the contents L is stored through a passage opening 31 formed in the supply part 30.

The portion of the container 100 to which the attachment part 10 is attached is, for example, the mouth 110 of the container 100. Therefore, the attachment part 10 has an outer tube 11 and an inner tube 12 that contact the outside and inside of the mouth 110 of the container 100, and an upper wall 13 that connects the upper ends of the outer tube 11 and the inner tube 12. Note that the attachment part 10 is not limited to the example shown in FIG. 1, and may be attached to a portion other than the mouth 110 as long as it can be attached to the container 100. An example in which the attachment part 10 is attached to a portion other than the mouth 110 will be described later as embodiment 2.

The contents L of the container 100 may be any fluid material, such as a powder or liquid. Examples of such liquids include liquid seasonings such as soy sauce, sauce, or dressing. Other examples of such liquids include fabric softeners, liquid laundry detergents, liquid bath additives, and cosmetics. In the following, liquids with a viscosity of 100 to 1000 mPa·s are referred to as medium-viscosity liquids.

The inside of the supply unit 30 is connected to the container 100 via the attachment unit 10. Therefore, the supply unit 30 is supplied with the contents L by squeezing the container 100, and the contents L flow back into the container 100 due to its own weight. Furthermore, the passage port 31 of the supply unit 30 is an opening that communicates the inside of the supply unit 30 with the measuring tube 40 and allows the contents L to pass through. The supply unit 30 has, for example, a nozzle 32 that rises from the bottom surface of the measuring tube 40, and a dome 33 that is provided inside the tip of the nozzle 32 and is located above the nozzle 32. The passage port 31 is, for example, a gap between the nozzle 32 and the dome 33.

In accordance with the gist of the present invention, the supply unit 30 has a nozzle plate 34 that faces the passage opening 31 from the measuring tube 40 side. This nozzle plate 34 is hit by the contents L discharged from the passage opening 31, thereby preventing the contents L from scattering. The nozzle plate 34 also prevents the contents L from leaking out of the passage opening 31 when the container 100 to which the attachment unit 10 is attached is tilted. The nozzle plate 34 is connected to the tip of the nozzle 32, for example.

The supply unit 30 is preferably located inside the measuring tube 40, in other words, it is preferably surrounded by the measuring tube 40. In addition, the nozzle plate 34 of the supply unit 30 is preferably shaped to extend all around, facing the passage opening 31 on the inside and facing the measuring tube 40 on the outside. With this configuration, the nozzle plate 34 is shaped to extend all around, and is sufficiently large relative to the passage opening 31, thereby sufficiently suppressing the scattering of the contents L. In addition, the nozzle plate 34 that extends all around also acts as a plate that blocks the contents L filled in the measuring tube 40. Furthermore, the upper end of the nozzle plate 34 that extends all around is preferably lower than the upper end of the measuring tube 40, and more preferably is at the same height as the upper end of the dome 33.

The passage opening 31 of the supply unit 30 is preferably 0.06 ^mm2 or more and 6.4 ^mm2 or less. Specifically, when the passage opening 31 is a rectangle having a vertical width and a horizontal width, the vertical width (or horizontal width) is preferably 0.3 mm or more and 1.6 mm or less, and the horizontal width (or vertical width) is preferably 0.2 mm or more and 4.0 mm or less. By having this area or shape, when the content L is a medium viscosity liquid, the content L can be smoothly discharged into the measuring tube 40 by squeezing the container 100, while the content L is more unlikely to leak out when the container 100 is tilted.

Up to this point, the measuring cap 1 according to the present embodiment 1 has been described, but the container 101 with measuring cap according to the present embodiment 1 includes the measuring cap 1 and a container 100 to which the mounting portion 10 of the measuring cap 1 is attached.

The following describes how to use the measuring cap 1 and the measuring cap-equipped container 101 equipped with the measuring cap, with reference to Figures 1 to 5.

First, when the container 100 of the container with a measuring cap 101 shown in Fig. 1 is squeezed, the content L of the container 100 is supplied to the supply unit 30 via the attachment unit 10 of the measuring cap 1, as shown in Fig. 2, and is then discharged from the passage port 31 into the measuring tube 40. Here, when the content L is a liquid of medium viscosity, the discharge is performed even if the passage port 31 is less than 0.06 ^mm2 (e.g., the vertical width is less than 0.3 mm and the horizontal width is less than 0.2 mm), but the discharge is performed smoothly if the passage port 31 is 0.06 ^mm2 or more (e.g., the vertical width is 0.3 mm or more and the horizontal width is 0.2 mm or more).

The discharged contents L do not hit the measuring tube 40 directly, but hit the nozzle plate 34 first and are guided to the measuring tube 40, preventing scattering. The contents L that hit the nozzle plate 34 are guided to the measuring tube 40 and are filled into the measuring tube 40 until they are higher than the top end of the nozzle plate 34.

Thereafter, when the squeeze is stopped, as shown in FIG. 3, the contents L of the measuring tube 40 flow back due to its own weight from the passage port 31 through the supply section 30 and the attachment section 10 into the container 100. Thus, as shown in FIG. 4, when the upper end of the contents L descends to the upper end of the nozzle plate 34, the contents L are blocked by the nozzle plate 34 and a predetermined amount of the contents L is stored in the measuring tube 40.

5, by tilting the container 100, the contents L of the measuring tube 40 (i.e., a predetermined amount of the contents L) are poured out from the measuring tube 40. Here, when the contents L are a liquid of medium viscosity, even if the passage opening 31 is larger than 6.4 ^mm2 (e.g., the vertical width is larger than 1.6 mm and the horizontal width is larger than 4.0 mm), the contents L are unlikely to leak out of the passage opening 31 when the container 100 is tilted, but if the passage opening 31 is 6.4 ^mm2 or less (e.g., the vertical width is 1.6 mm or less and the horizontal width is 4.0 mm or less), the contents L are even less likely to leak out of the passage opening 31 when the container 100 is tilted.

In this way, with the measuring cap 1 and the measuring capped container 101 equipped with the same, the nozzle plate 34 facing the passage port 31 can prevent the contents L ejected from the passage port 31 from scattering.

Furthermore, since the nozzle plate 34 that extends around the entire periphery is sufficiently large relative to the passage port 31, scattering of the contents L ejected from the passage port 31 can be sufficiently suppressed.
[Embodiment 2]

Below, a measuring cap and a container with a measuring cap including the same according to the second embodiment of the present invention will be described. In the container with a measuring cap according to the second embodiment, the measuring cap 1 is a spout and the container 100 is a pouch in the container with a measuring cap 101 according to the first embodiment. In the second embodiment, the description will focus on the configuration that is different from the first embodiment, and the same configuration as the first embodiment will be assigned the same reference numerals and the description thereof will be omitted.

As shown in FIG. 6, the measuring cap 2 according to the second embodiment includes a spout 1 corresponding to the measuring cap 1 according to the first embodiment, and a top lid 20 that can be attached and detached to the spout 1. The container 102 with a measuring cap according to the second embodiment includes the spout 1, the top lid 20, and a pouch 100 corresponding to the container 100 according to the first embodiment.

The top cover 20 has a top wall 21, a skirt 22 provided on the outer periphery of the top wall 21, and a sealing portion 23 provided on the underside of the top wall 21. The skirt 22 has an inner peripheral screw portion 24 on the inside of its lower part.

The measuring tube 40 of the spout 1 has an outer peripheral threaded portion 42 on the outside of its lower portion that threads into the inner peripheral threaded portion 24 of the top lid 20. The measuring tube 40 also has an upper end portion 43 with an expanded diameter. This expanded upper end portion 43 is the portion that is sealed by contacting the sealing portion 23 of the top lid 20 when the inner peripheral threaded portion 24 threads into the outer peripheral threaded portion 42.

As shown in FIG. 7, the supply section 30 of the spout 1 has a base 35 connected to the upper wall 13 of the mounting section 10, and an upper section 37 having a smaller diameter than the base 35. The base 35 has a straightening rib 36 on the inside thereof for straightening the flow of the contents L. As shown in FIG. 8, there are a plurality of straightening ribs 36, which are arranged at equal intervals. As shown in FIG. 7, the upper section 37 has the passage opening 31, dome 33, and nozzle plate 34 described in the first embodiment. In the first embodiment, the number of passage openings 31 is arbitrary, but in the second embodiment, there is only one passage opening 31.

The following describes how to use the measuring cap 2 according to the second embodiment and the measuring cap-equipped container 102 equipped with the measuring cap, with reference to Figures 6 to 8.

First, as shown in FIG. 6, the inner peripheral threaded portion 24 of the top cover 20 is threadedly engaged with the outer peripheral threaded portion 42 of the spout 1 (the top cover 20 is attached to the spout 1), and this threaded engagement is released (the top cover 20 is released from the spout 1).

After that, the method of use is the same as that described in the first embodiment. Here, since there is only one passage opening 31, air replacement is unlikely to occur inside the pouch 100. That is, the contents L poured out from the pouch 100 through the spout 1 are not replaced by air inside the pouch 100, in other words, even when the contents L are poured out, almost no air gets into the pouch 100. This prevents the undesirable phenomenon of air getting into the pouch 100.

In this way, the measuring cap 2 according to the second embodiment and the measuring capped container 102 equipped with the same can achieve the effects described in the first embodiment, and can also prevent air from entering the pouch 100.

In addition, the straightening rib 36 straightens the flow of the contents L at the base 35 of the nozzle 32, so that the straightened contents L are discharged from the passage port 31, further preventing the contents L from scattering.

In the first and second embodiments, the section from the supply unit 30 to the container 100 (pouch 100) was not described in detail, but it is preferable that no valve is provided in this section. This is because not providing this valve allows the content L to flow smoothly back from the supply unit 30 shown in FIG. 3 to the container (pouch 100).

Furthermore, the above-mentioned first and second embodiments are illustrative in all respects and are not restrictive. The scope of the present invention is indicated by the claims, not by the above description, and is intended to include all modifications that are equivalent in meaning and scope to the claims. Among the configurations of the measuring caps 1 and 2 described in the above-mentioned embodiments for implementing the invention, those other than the configuration described as the first invention in the "Means for solving the problem" are optional configurations and may be deleted or modified as appropriate.
