  The present invention relates to a double container with a pump capable of mixing contents individually filled in two containers.

  As a conventional double-type container, for example, a container that has an opening at the lower end of the body and that can be slid inside the container can be used to increase or decrease the filling space leading to the mouth, and the container A partition wall having an opening communicating with the mouth portion, and a base on which the two containers are mounted in parallel, and by simultaneously pushing in the inner plates placed inside the two containers, different containers After the filled contents are mixed inside the base, there is one that is taken out to the outside through a spout of the base (see, for example, Patent Document 1).

JP 2006-150229 A

  However, since the conventional double-type container realizes mixing of the contents by simultaneously pushing the two inner dishes, the mixing method is only uniquely determined, so it is desired to select a different mixing method. Sometimes not applicable. For this reason, when selecting a different mixing method, it is necessary to change or replace the components of the duplex container, or to replace the duplex container itself.

  Moreover, since the process which mixes the content and the process of taking out the subsequent contents are performed in synchronization with the movement of the inner tray, the above-described double-type container takes out the contents while adjusting the mixing state. Is difficult.

  It is an object of the present invention to select two different mixing methods without changing or exchanging parts, and with a pump with two pumps that can easily take out the contents while adjusting the mixing state. It is to provide a type container.

The duplex container with a pump of the present invention comprises a tube container having a deformable body and capable of increasing / decreasing a filling space leading to the mouth part, and a partition wall formed with an opening part leading to the mouth part of the tube container. It has a base that is mounted in parallel with the two mouths and a pump that is driven by repeated pressing down and return of the head, and the mounting is performed while maintaining a liquid-tight relationship between the mounting cylinder that stands up from the base. A cap to be attached to the cylinder,
While the cap is capable of rotating around the mounting cylinder while maintaining fluid tightness with the mounting cylinder of the base,
By holding liquid tightly between the cylindrical portion that rises from the partition wall of the base and the cylindrical portion that hangs down from the cap, a first space is formed inside the cylindrical portion, and the cylinder of the base Forming a second space surrounded by the cap and the cap,
Furthermore, a passage that opens and closes between the first space and the second space according to the rotational position of the cap is provided between the two cylindrical portions,
Wherein the first space is a space with leading to the suction port of the pump, by deformation of the body of at least one of the tubular container, the contents filled in the different tube container to allow mixing of the contents by circulating It is characterized by becoming .

According to the invention, said passage, a groove formed in one of the two said tubular portion, together with the form by the two slits formed in the other of said tubular portion,
The opening leading to tube containers while formed in the partition wall, with the first opening providing communication with the first space, said opening leading to the other tube containers formed in the partition wall, It can be set as the 2nd opening part connected to the said 2nd space.

Further, according to the present invention, the passage, a groove formed in one of the two said tubular portion, together with the form by the two slits formed in the other of said tubular portion,
The partition wall forming the two said openings leading to tube containers respectively, may be an opening for providing communication to the second space.

  Further, when the two mouth portions are mounted on the base, the two tube containers can be configured as separate bodies or as a single body. According to the present invention, the tube container can be made of a material that can be seen through. Examples of the transparent material include those made of a transparent or translucent material.

  In the present invention, the contents are mixed by allowing the contents filled in different tube containers to circulate between the base and the cap through the suction port of the pump and by deformation of the body of at least one of the tube containers. By providing the space that enables it, the contents of the two tube containers can be freely distributed. Thereby, if a pump is operated, the mixture according to liking can be taken out.

  For example, by holding liquid tightly between the cylindrical portion that rises from the partition wall of the base and the cylindrical portion that hangs down from the cap, a first space that leads to the suction port of the pump is formed inside thereof. Each of the two cylindrical portions opens and closes between the second space and the first space surrounded by the cylindrical portion of the base and the cap between the cylindrical portions according to the rotational position of the cap. Grooves and slits are provided in which the passages are formed.

  At this time, the opening that leads to the one tube container formed in the partition wall serves as the first opening that leads to the first space, and the opening that leads to the other tube container formed in the partition wall serves as the second space. With the second opening to be communicated, when the passage between the second space and the first space is closed by the rotation of the cap, only the mouth portion of one tube container communicates with the first space. When the pump is driven by repeatedly pressing down and returning, only the contents of one tube container can be taken out from the spout formed in the head. In this case, for example, when the contents filled in the tube container have different colors, the color of the content to be taken out exhibits the color of either one of the contents.

  On the other hand, when the passage between the second space and the first space is opened by the rotation of the cap, both the mouth portions of the two tube containers communicate with the first space. When the pump is driven, the contents filled in the two tube containers can be taken out from the spout formed in the head while being mixed in the first space. In this case, for example, if the contents filled in the tube container have different colors, the color of the contents to be taken out exhibits a color in which the colors of the two contents are mixed.

  In addition, when the passage between the second space and the first space is opened by the rotation of the cap, if the body of at least one tube container is handled and deformed, the one tube container is filled. When the content thus obtained flows toward the other tube container through the first space, mixing with the content filled in the other tube container becomes possible.

  The deformation of the tube container may be at least once, but after that, if the body of the other tube container is handled and deformed, the content mixed in the other tube container will be in the first space. Then, the contents are further mixed toward the one tube container, whereby the mixing of the contents is further improved. That is, if the deformation of the body of one tube container and the deformation of the body of the other tube container are repeated, the mixed state of the contents can be adjusted according to preference.

  Thereby, when the pump is driven by repeatedly pressing down and returning the head, the mixture adjusted according to the user's preference can be taken out from the spout formed in the head. In this case, for example, if the contents filled in the tube container have different colors, the color of the contents to be taken out is a color in which the colors of the two contents are mixed, but the tube container is not operated. Compared to the case, it presents a more complex color. This complex color exhibits a complex color as the number of times of operation of the tube container increases.

  Alternatively, by holding liquid tightly between the cylindrical portion that rises from the partition wall of the base and the cylindrical portion that hangs down from the cap, a space that leads to the suction port of the pump is formed inside thereof, and 2 Each of the cylindrical portions has a passage that opens and closes between the second space and the first space surrounded by the cylindrical portion of the base and the cap between the cylindrical portions according to the rotational position of the cap. When the grooves and slits to be formed are provided, the openings connected to the two tube containers formed in the partition wall are the openings that respectively connect to the second space, so that the second space and the first space are rotated by the rotation of the cap. When the passage between the two tubes is opened, both the mouth portions of the two tube containers communicate with the first space. Therefore, when the pump is driven by repeatedly depressing and returning the head, the contents filled in the two tube containers are removed. First It can be taken out from the spout formed in the head while mixing in space. Also in this case, for example, if the contents filled in the tube container have different colors, the color of the taken-out contents exhibits a color in which the colors of the two contents are mixed.

  In addition, if the body of at least one tube container is handled and deformed, the contents filled in the one tube container are circulated toward the other tube container through the first space. , Mixing with the contents filled in the other tube container becomes possible.

  In this case as well, the deformation of the tube container may be at least once, but if the body is deformed by handling the body of the other tube container, the contents mixed in the other tube container are not changed. By flowing again toward the one tube container through the first space, mixing of the contents is further improved. That is, also in this case, if the deformation of the body of one tube container and the deformation of the body of the other tube container are repeated, the mixed state of the contents can be adjusted according to preference.

  Accordingly, when the pump is driven by repeatedly pressing down and returning the head, the mixture adjusted according to the user's preference can be taken out from the spout of the head. Also in this case, for example, if the contents filled in the tube container have different colors, the color of the contents to be taken out is a color in which the colors of the two contents are mixed, but the tube container is operated. Compared to when not, it presents a more complex color. This complex color also exhibits a more complex color as the tube container is operated more frequently.

  On the other hand, when the passage between the second space and the first space is closed by the rotation of the cap, although the deformation of the tube container is allowed, even if the pump is driven by repeatedly pushing down and returning the head, No content or mixture is removed from the spout of the head. Thereby, even if the head is erroneously operated, the contents and the mixture are not erroneously taken out.

  In addition, since the present invention is configured to take out the contents and the mixture by driving the pump by repeatedly depressing and returning the head, the step of deforming the tube container and mixing the contents, and the subsequent contents The step of taking out can be performed independently of the deformation of the tube container. Thereby, according to this invention, as above-mentioned, the content can be taken out, adjusting a mixing state.

  That is, according to the present invention, the amount and speed of mixing can be switched by distributing the contents between containers and switching the passages. As a result, the mixture taken out from the head can be freely changed in color by changing the color gradually or rapidly, such as a stripe pattern or a marble pattern, depending on the amount and speed of mixing.

  Therefore, according to the present invention, it is possible to select different mixing methods without changing or exchanging parts, and a dual system with a pump that can easily take out contents while adjusting the mixing state. A container can be provided.

  Further, if the tube container is made of a material that can be seen through, the state of the contents can be visually observed, so that in addition to the effects described above, a visual effect can also be enhanced.

It is a 1st form of this invention, and is a side view which shows the state before mixing of the content in a partial cross section. (a)-(c) is the principal part perspective view which shows the assembly | attachment state of the cylindrical part which forms the channel | path which opens and closes between 2nd space and 1st space in the same form, respectively from the partition wall of a base It is the principal part perspective view which shows the cylindrical part to stand, and the principal part perspective view which shows the cylindrical part drooping from a cap.

It is a side view which shows the process in which a mixture is taken out by operating a head in the same form in a partial cross section.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

1 to 5, reference numeral 10 denotes a tube container that can be deformed by a force applied from the outside world. The tube container 10 has a mouth portion 10a, and a tail portion 10c is formed by sealing the rear end of the deformable body 10b. Thus, for example, by handling the body 10b from the tail portion 10c toward the mouth portion 10a, the filling space _R0 leading to the mouth portion 11a can be increased or decreased.

  In this embodiment, the two tube containers 10 are integrally connected to each other so as to be configured as an integral container having two ports 10a. However, the two tube containers 10 are configured as separate bodies. It is also possible.

Reference numeral 13 denotes a base having a partition wall 13a in which openings A ₂ and A ₃ communicating with the mouth portion 10a are formed, and two mouth portions 10a are respectively mounted in parallel. From the partition wall 13a, two mounting tubular 13b ₁ is suspended, the hollow mounting 13b _1, respectively, that are fitted undercut the mouth portion 11a, the two neck portions 10a, respectively, are attached to the base 13 The The base 13 has a seal cylinder 13b ₂ that holds the mouth portion 11a together with the mounting cylinder 13b ₁ . Thereby, each of the mouth portions 10a is held liquid-tight with respect to the base 13.

Reference numeral 14 denotes a cap that has a pump 15 and is rotatable around an axis O with the base 13 as a base point. The cap 14 includes a mounting cylinder 14a ₁ that surrounds the mounting cylinder 13c that stands up from the base 13 and that is rotatably undercut fitted to the mounting cylinder 13c.

The cap 14 has a seal cylinder 14a ₂ that holds the mounting cylinder 13c on the base side together with the mounting cylinder 14a ₁ . As a result, the cap 14 can rotate around the mounting cylinder 13c while being liquid-tightly maintained between the cap 14 and the mounting cylinder 13c on the base side.

  Reference numeral 15 denotes a pump having a head 15 a and fixed to the cap 14. The pump 15 has a pump body 15b that is driven by repeatedly pressing down and returning the head 15a. As the configuration of the pump main body 15b, for example, as shown in FIG. 1, there is an existing one in which a plunger, a piston, or the like is built in a cylinder 15c.

Further, in this embodiment, the cylindrical portion 13d rises integrally from the partition wall 13a of the base 13. In order to correspond to this, the cylindrical portion 14 c also hangs down from the cap 14. The cylindrical portion 14c has an inner peripheral surface 14f that surrounds the outer peripheral surface 13f of the cylindrical portion 13d, and maintains a liquid-tight relationship with the cylindrical portion 13d. As a result, a first space R ₁ communicating with the suction port A ₄ of the pump 15 is formed inside the cylindrical portion 13d.

In addition, in this embodiment, as shown in FIG. 2A, two slits S opened at the upper end are formed in the cylindrical portion 13d. In order to correspond to this, as shown in FIG. 2 (b), two grooves G are formed in the inner peripheral surface 14f of the cylindrical portion 14c. Accordingly, when the cap 14 is rotated, the second space surrounded by the cylindrical portion 13d and the cap 14 is formed between the cylindrical portions 13d and 14c according to the rotation position, as shown in FIG. A passage P that opens and closes between R ₂ and the first space R ₁ is formed.

Furthermore, in this embodiment, one opening A ₂ formed in the partition wall 13a is used as a first opening that communicates with the first space R ₁ , and the other opening A ₃ formed in the partition wall 13a is used as the first opening. The second opening (A ₃ ) communicates with the two spaces.

In the present embodiment, the space between the cylindrical portion 13d that rises from the partition wall 13a of the base 13 and the cylindrical portion 14c that hangs down from the cap 14 is liquid-tightly held, so that the suction port A ₄ of the pump 15 is provided inside thereof. The first space R ₁ leading to the cylindrical portion is formed, and the cylindrical portions of the base 13 are provided between the cylindrical portions 13 d and 14 c in accordance with the rotational position of the cap 14. A groove G and a slit S are provided in which a passage P is formed to open and close between the second space R ₂ and the first space R ₁ surrounded by 13d and the cap 14.

Therefore, as in the present embodiment, the opening A ₂ that leads to one tube container 10 formed in the partition wall 13a is used as the first opening that leads to the first space R ₁ and the other formed in the partition wall 13a. If the opening A ₃ communicating with the tube container 10 is a second opening communicating with the second space R ₂ , the passage P between the second space R ₂ and the first space R ₁ by the rotation of the cap 14. when the is closed, as shown in FIG. 1 and FIG. 3 (a), only the mouth portion 11a of one of the tubular container 10 lead into the first space R _1, the pump 15 by repeating depressing and returning the head 15a When driven, only the contents C _{1 of one} tube container 10 can be taken out from the spout A ₅ formed in the head 15a. In this case, for example, if the contents C ₁ and C ₂ filled in the container 10 have different colors, the color to be taken out exhibits one of the contents C ₁ and C ₂ .

On the other hand, as shown in FIG. 3B and the like, when the passage P between the second space R ₂ and the first space R ₁ is opened by the rotation of the cap 14, the mouth portions of the two tube containers 10 are opened. since both 10a is lead to the first space R _1, when driving the pump 15 by repeating depressing and returning the head 15a, the contents filled in the two tubular container 10 to C _1, C ₂ first space can be removed from the spout a ₅ formed in the head 15a while mixing at R _1. In this case, for example, when the contents C ₁ and C ₂ filled in the container 10 have different colors, the color of the mixture C _{3 to} be taken out is a mixture of the two contents C ₁ and C ₂ . Presents color.

In addition, when the passage P between the second space R ₂ and the first space R ₁ is opened by the rotation of the cap 14, at least as shown in FIG. 4, for example, the body 10 b of one tube container 10. The contents C ₁ filled in the one tube container 10 circulates toward the other tube container 10 through the first space R ₁ , so that the other tube container 10 is deformed. Mixing with the contents C ₂ filled in the container 10 becomes possible.

As described above, the tube container 10 may be deformed at least once. However, if the tube container 10 is deformed by handling the body 10b of the other tube container 10, the tube container 10 is mixed in the other tube container 10. The mixed contents C ₃ (C ₁ + C ₂ ) flow again toward the one tube container 10 through the first space R ₁ , so that the contents C ₁ and C ₂ are further mixed. That is, if the deformation of the body 10b of one tube container 10 and the deformation of the body 10b of the other tube container 10 are repeated, the mixed state of the contents C ₁ and C ₂ can be adjusted according to preference.

Thus, when driving the pump 15 by repeating depressing and returning the head 15a, as shown in FIG. 5, the mixture C _3, which is adjusted according to the preference of the user from the spout A ₅ which is formed in the head 15a It can be taken out. Also in this case, for example, if the contents C ₁ and C ₂ filled in the tube container 10 have different colors, the color of the mixture C _{3 to} be taken out is the color of the two contents C ₁ and C ₂ . Although it exhibits a mixed color, it presents a more complex color than when the tube container 10 is not operated. This complicated color exhibits a more complex color as the tube container 10 is operated more frequently.

In addition, in this embodiment, the contents C ₁ , C ₂ and the mixture C ₃ are taken out by driving the pump 15 by repeatedly pressing down and returning the head 15 a, so that the contents are obtained by deforming the tube container 10. The step of mixing C ₁ and C ₂ and the subsequent step of taking out the contents C ₁ and C ₂ can be performed regardless of the deformation of the tube container 10. Thus, according to this embodiment, as described above, while adjusting the mixed state can be taken out the contents C _1, C _2.

Therefore, according to this embodiment, it is possible to select different mixing methods without changing or replacing parts, and it is possible to easily take out the contents C ₁ and C ₂ while adjusting the mixing state. A dual container with a pump can be provided.

Next, FIGS. 6 to 9 show a double container 200 with a pump according to the second embodiment of the present invention. In this embodiment, the second opening A ₃ to establishing communication opening communicating with two containers 10 formed in the partition wall 13a of the second space R _2, respectively.

Similarly to the first embodiment, this embodiment also holds a liquid-tight space between the cylindrical portion 13d that rises from the partition wall 13a of the base 13 and the cylindrical portion 14c that hangs down from the cap 14, so that A first space R ₁ communicating with the suction port A ₄ of the pump 15 is formed, and the two cylindrical portions 13d and 14c are provided between the cylindrical portions 13d and 14c according to the rotational position of the cap 14, respectively. A groove G and a slit S are provided in which a passage P is formed to open and close between the second space R ₂ and the first space R ₁ surrounded by the cylindrical portion 13 d of the base 13 and the cap 14.

Therefore, as in the present embodiment, if the opening A ₃ to establishing communication opening communicating with two tubular container 10 which is formed in the partition wall 13a of the second space R ₂ respectively, the second space R by rotation of the cap 12 _When the passage P between the first space R ₁ and the first space R ₁ is opened, both the mouth portions 11a of the two tube containers 10 communicate with the first space R ₁ , so that the pump 15 is repeatedly pushed down and returned. Is driven, the contents C ₁ and C ₂ filled in the two tube containers 10 can be taken out from the spout A ₅ formed in the head 15 a while being mixed in the first space R ₁ . Also in this case, for example, when the contents C ₁ and C ₂ filled in the container 10 have different colors, the color of the mixture C _{3 to} be taken out is a mixture of the colors of the two contents C ₁ and C _2. Presents a different color.

In addition, as shown in FIG. 8, at least, if the body 10b of one container 10 is handled and deformed, the contents C ₁ filled in the one tube container 10 become the first space R _1. It circulates toward the other tube container 10 via, and mixing with the contents C ₂ filled in the other tube container 10 becomes possible.

Also in this case, the deformation of the tube container 10 may be at least once, but after that, if the body 10b of the other tube container 10 is handled and deformed, the tube container 10 is mixed in the other tube container 10. The content C ₃ (C ₁ + C ₂ ) flows again toward the one tube container 10 through the first space R ₁ , so that the mixing of the contents C ₁ and C ₂ is further improved. That is, also in this case, if the deformation of the body 10b of one tube container 10 and the deformation of the body 10b of the other tube container 10 are repeated, the mixed state of the contents C ₁ and C ₂ is adjusted according to preference. be able to.

Thus, when driving the pump 15 by repeating depressing and returning the head 15a, it is possible to take out the mixture prepared in accordance with the preference of the user from the spout A ₅ of the head 15a. Also in this case, for example, when the contents C ₁ and C ₂ filled in the container 10 are different in color, the color of the mixture C _{3 to} be taken out is a mixture of the two contents C ₁ and C _2. Although presenting a matching color, it presents a more complex color than when the tube container 10 is not operated. This complex color also exhibits a more complex color as the tube container 10 is operated more frequently.

On the other hand, when the passage P between the second space R ₂ and the first space R ₁ is closed by the rotation of the cap 14, the tube container 10 is allowed to be deformed, but the head 15a is repeatedly pushed down and returned. Even if the pump 15 is driven, the contents C ₁ and C ₂ and the mixture C ₃ are not taken out from the spout A _{5 of the} head 15a. Thereby, even if the head 15a is operated by mistake, the contents C ₁ and C ₂ and the mixture C ₃ do not need to be taken out by mistake.

In addition, since the present embodiment is also configured to take out the contents C ₁ , C ₂ and the mixture C ₃ by driving the pump 15 by repeatedly pushing down and returning the head 15a, as in the first embodiment, the tube container a step of 10 to deform the mix the contents of C _1, C _2, the a step of retrieving the subsequent content C _1, C ₂ can be carried out independently of the deformation of the tube container 10. Thus, according to this embodiment, as described above, while adjusting the mixed state can be taken out the contents C _1, C _2.

That is, according to the present embodiment, the amount and speed of mixing can be switched by distributing the contents C ₁ and C ₂ between the tube containers 10 and switching the passages P. As a result, the mixture C ₃ taken out from the head 15a can be freely discolored by gradually or rapidly changing the color, such as a stripe pattern or a marble pattern, depending on the amount and speed of mixing. .

Therefore, according to this embodiment, a different mixing method can be selected without changing or exchanging parts, and the contents C ₁ and C ₂ can be easily taken out while adjusting the mixing state. A double-type container can be provided.

Moreover, according to this invention, both the above-mentioned 1st form and 2nd form can be comprised with the transparent or semi-transparent material which can see through the trunk | drum 11b of the container 10. FIG. In this case, since the states of the contents C ₁ and C ₂ can be visually observed, a visual effect can be enhanced in addition to the above-described effects.
