Abstract

PROBLEM TO BE SOLVED: To provide a bag storage container that eliminates need for troublesome replacement of contents to a different specific container from the bag and that makes the contents less likely to contact air.SOLUTION: While the body of a bag 10 is accommodated inside a container body 3, the spout 2 of the bag 10 is pulled out from the spout pull-out hole 5 of the container body 3, thus discharging the contents from the spout 2 of the bag 10 can be made. Handling of the flexible bag 10 becomes easier by accommodating it in the container body 3, compared to the case of using this bag 10 as it is. Since the contents can be discharged from the spout 2 of the bag 10, the need for troublesome conventional replacement of the contents from the bag to a specific container is eliminated. The contents are discharged while they are kept in the flexible bag 10. Thus, a quantity of air flowing into the bag 10 can be minimized as a result of a decrease in the volume of the bag 10 squeezed to use the contents.

Description

  The present invention relates to a bag storage container for storing a bag provided with a spout, and more particularly to a bag storage container capable of discharging the contents of a bag from a spout.

  In order to reduce the amount of garbage, there is a product that allows only the contents of the container to be refilled so that the container itself can be used repeatedly. For example, products in which liquid contents such as liquid detergents, hair washing agents, liquid soaps, and liquid seasonings are filled in bags are sold as refill packs. In general, the refill pack is provided with a spout, and the refilling operation is performed by pouring the liquid contents from the spout of the refill pack into the mouth of a dedicated container whose contents are empty. .

However, as described above, the operation of pouring the contents from the refill pack into the dedicated container is very complicated, and there is a problem that the contents are spilled if not used.
In addition, since the dedicated container is made of a relatively hard material such as plastic or glass, when the contents are reduced, the air corresponding to the reduced amount enters the inside of the container, and the contents are chemically mixed with the air. There is a problem that a reaction (oxidation or the like) easily occurs. Even if the contents do not cause a chemical reaction with the air, if a space is generated inside the container, there is a problem that the concentration of the components in the liquid changes due to evaporation of the components of the contents in the space. .
Furthermore, since there are various types of dedicated containers, there is a problem that efficient storage becomes difficult as the number of types increases.

  The present invention has been made in view of such circumstances, and its purpose is a bag storage container for storing a bag filled with contents, and a complicated operation for transferring the contents from the bag to another dedicated container. It is an object of the present invention to provide a bag container that can make the contents difficult to come into contact with air.

A bag container according to the present invention includes a sealed container body that houses a bag having a spout for pouring out contents, and penetrates from the inside to the outside of the container body, A spout outlet hole for pulling out the spout of the bag to the outside of the container body while maintaining airtightness;
A vent hole penetrating from the inside of the container body to the outside and the pressure inside the container body closes when the pressure inside the container body becomes higher than the outside pressure, and the pressure inside the container body is compared with the outside pressure. A material that can be deformed according to the force applied from the outside and can be restored to its original shape when the force from the outside is lost. Formed by.

  Preferably, the valve includes an elastic sheet-like member that closes the vent hole inside the container body, and a fixing unit that fixes a part of the sheet-like member to the inside of the container body. Good.

  Preferably, the container main body is separable into a plurality of parts each forming a part of an outer shell that forms an inner space of the bag, and the spout outlet hole is formed on the separable outer shell. It may be formed at a boundary where a part and another part are joined. The bag container may include the spout between the one recessed portion of the spout outlet hole formed in the portion and the other recessed portion of the spout outlet hole formed in the other portion. May be sandwiched and held.

  Suitably, the said bag storage container may have the packing provided in the surface where the said part and said other part of the said container main body are couple | bonded. The bag container may have a packing that is provided in the one recess of the spout outlet hole and / or the other recess of the spout outlet hole and is in close contact with the spout hole. .

  According to the present invention, since the contents can be taken out from the spout of the bag and used while the contents are filled in the bag, there is no need to transfer the contents of the bag to the dedicated container. Moreover, when a bag deform | transforms according to the reduction | decrease of the volume of a content, it can make it difficult to contact a content and air.

It is a figure which shows the example of the bag storage container of the state in which the bag is not accommodated inside. It is a figure which shows the example of an external appearance of the state which opened the bag storage container. It is a figure which shows the example of the cross section of a container main body. It is a figure which shows an example of the valve seen from the inner side of the container main body.

Hereinafter, a bag container according to an embodiment of the present invention will be described with reference to the drawings.
The bag storage container according to the present embodiment stores a flexible bag 10 (refill pack) filled with liquid contents such as a liquid detergent, a hair wash, a liquid soap, and a liquid seasoning. Container. This bag container has a structure in which the main body of the bag 10 is hermetically housed inside with the spout 2 of the bag 10 pulled out. When the bag container is deformed by applying a force with a finger or the like from the outside, the pressure of the air sealed in the bag container increases, and this pressure is applied to the entire bag 10 so that the contents of the bag 10 are changed. It is pushed out of the extraction port 2. When the external force applied to the bag storage container is loosened, the shape of the bag storage container is restored to the original state, and the valve 4 provided in the bag storage container is opened to allow air to flow into the interior. When air flows in from the valve 4, the volume of the reduced content is supplemented by the air, so that the negative pressure inside the bag storage container is released.

FIG. 1 is a diagram illustrating an example of a bag storage container according to the present embodiment. FIG. 2 is a diagram illustrating an example of the bag storage container in a state where the bag 10 is not stored therein. FIG. 3 is a view showing an example of an appearance in a state where the bag storage container is opened and the bag 10 can be taken in and out.
The bag container shown in FIGS. 1 to 3 includes a sealed container body 3 that houses a bag 10 filled with liquid contents, a spout outlet hole 5, a vent hole 6, and a valve 4. .
The container body 3 is an example of a container body in the present invention, the spout outlet hole 5 is an example of a spout outlet hole in the present invention, the vent hole 6 is an example of a vent hole in the present invention, and the valve 4 Is an example of a valve in the present invention.

  The bag 10 is a bag formed of a flexible sheet-like material (such as a synthetic resin), and is filled with, for example, a liquid content. The bag 10 includes a main body portion that is filled with the contents, and a spout 2 for pouring the contents. For example, as shown in FIG. 3, the main body of the bag 10 has a substantially rectangular shape when viewed from the front. The lateral width seen from the side surface direction of the main body of the bag 10 gradually increases from the top side toward the bottom side.

  For example, as shown in FIG. 3, the spout 2 of the bag 10 protrudes in a cylindrical shape on the upper side of the bag 10, and a hole 21 communicating with the inside of the main body of the bag 10 is formed at the center. A screw 23 for mounting a cap 22 that closes the hole 21 is formed at the tip of the spout 2. A screw (not shown) formed on the inner wall of the cap 22 and a screw 23 formed on the tip of the spout 2 are screwed together, so that the cap 22 is mounted on the tip of the spout 2 and the hole 21 is formed. Sealed. A groove 24 that fits with the edge of the spout outlet hole 5 is formed at the base of the spout 2 near the main body of the bag 10. By fitting the groove 24 of the spout 2 with the edge of the spout outlet hole 5, the spout 2 does not fall out of the spout outlet hole 5.

  The container body 3 is a hollow container formed of a material (such as a synthetic resin) that can be deformed according to a force applied from the outside and can be restored to its original shape when the force from the outside disappears. The container body 3 hermetically accommodates the body of the bag 10 in a state where the spout 2 is pulled out. 1-3, the container main body 3 has a rectangular parallelepiped shape with rounded corners.

  The container body 3 is separable into a plurality of portions that respectively form part of the outer shell that forms the accommodation space of the bag 10 inside. For example, the container body 3 shown in FIG. 3 has two portions (31, 32) that are separable on a plane parallel to a relatively large plane in the rectangular parallelepiped shape. With the container body 3 separated into the part 31 and the part 32, the bag 10 can be taken in and out.

  In the bag container according to the present embodiment, the portion 31 and the portion 32 are detachably coupled by a coupling means (not shown) including, for example, a claw and a hooking portion thereof. During normal use, the portion 31 and the portion 32 are joined by the joining means. When the bag 10 is taken in and out, the coupling means is released and the part 31 and the part 32 are separated.

  The spout outlet hole 5 is a hole penetrating from the inside of the container body 3 to the outside, and pulls out the spout 2 of the bag 10 to the outside of the container body 3 while maintaining airtightness inside the container body 3. For example, as shown in FIG. 3, the spout outlet hole 5 is formed on a boundary where two portions (31, 32) forming a part of the outer shell of the container body 3 are joined. When the container body 3 is separated into the part 31 and the part 32, the spout outlet hole 5 is separated into a semicircular recess 51 formed in the part 31 and a semicircular recess 52 formed in the part 32. . The bag 10 is held by the container body 3 by sandwiching the spout 2 of the bag 10 between the recess 51 and the recess 52. That is, half of the ring-shaped groove 24 of the spout 2 is fitted to the edge of the concave portion 51 and the other half is fitted to the edge of the concave portion 52, so that the entire circumference of the groove 24 is formed in the spout outlet hole 5. The spout 2 is fitted into the edge, so that the spout 2 does not fall out of the spout outlet hole 5.

  A packing 7 is provided on the surface where the portion 31 and the portion 32 of the container body 3 are joined to maintain the airtightness inside the container body 3. The packing 7 is made of a material having elasticity (for example, an elastomer such as silicon rubber), and closes a minute gap generated when the portion 31 and the portion 32 are joined. The packing 7 may be provided in one of the part 31 and the part 32, or may be provided in both.

  Moreover, the packing 7 is provided also in the recessed part 51 and the recessed part 52 which respectively form the spout extraction hole 5, as shown, for example in FIG. 3 (it may be provided only in one recessed part). The packing 7 closes a minute gap generated when the spout 2 is sandwiched between the recess 51 and the recess 52.

  The vent hole 6 is a hole penetrating from the inside of the container body 3 to the outside, and is used for introducing air into the container body 3.

  The valve 4 closes the vent hole 6 when the inner pressure of the container body 3 becomes higher than the outer pressure, and opens the vent hole 6 when the inner pressure of the container body 3 becomes lower than the outer pressure. That is, the valve 4 opens the vent hole 6 only when air flows from the outside to the inside according to the pressure difference between the inside and the outside of the container body 3.

FIG. 4 is a diagram illustrating an example of a cross section of the container body 3. FIG. 4 (A) shows a state where force is applied to the container body 3 from the outside with a finger or the like, and FIG. 4 (B) shows a state where the shape of the container body 3 has returned to its original shape by eliminating the external force. Show. FIG. 5 is a view showing an example of the valve 4 as seen from the inside of the container body 3.
The valve 4 shown in the example of FIGS. 4 and 5 has a sheet-like member 41 and a fixing member 42. The sheet-like member 41 is an example of the sheet-like member in the present invention, and the fixing member 42 is an example of the fixing means in the present invention.

  The sheet-like member 41 is a thin plate-like member formed of an elastic material (for example, an elastomer such as silicon rubber), and is disposed so as to close the vent hole 6 inside the container body 3. In the example of FIG. 6, the sheet-like member 41 has a circular portion, and closes the entire vent hole 6 near the center of the circular portion. Further, a rectangular portion protruding in the radial direction is provided at a part of the circumference of the circular portion, and the rectangular portion is fixed to the inner wall of the container body 3 by the fixing member 42. The fixing member 42 is, for example, a protrusion provided on the inner wall of the container body 3, and is inserted into the protrusion in a hole formed in the rectangular portion of the sheet-like member 41, thereby The part is fixed to the inner wall of the container body 3.

Here, the usage method of the bag container which has the structure mentioned above is demonstrated.
When the bag 10 is stored in the bag storage container, first, the coupling means (not shown) is released, and the container body 3 is separated into the part 31 and the part 32 (FIG. 3). Then, the bag 10 filled with the contents is prepared, and the bag 10 is put inside the portions 31 and 32 so that the groove 24 of the spout 2 is fitted to the edges of the recesses 51 and 52, and the portions 31 and 32 are It connects by a connection means. As a result, the main body of the bag 10 is housed inside the container main body 3.

  When the contents of the bag 10 are used, the cap 22 of the spout 10 is turned and removed, and the body of the container body 3 is pushed with a finger or the like. When the container body 3 is deformed and the internal volume decreases, the pressure inside the container body 3 becomes higher than the atmospheric pressure outside as shown by the size of the arrow in FIG. The sheet-like member 41 of the valve 4 is pressed against the inner wall of the container body 3 by the pressure difference between the inside and the outside of the container body 3. When the sheet-like member 41 is in close contact with the inner wall, the vent hole 6 is completely closed, and the inside of the container body 3 is sealed. When the container body 3 is further strongly pressed in the sealed state, the pressure inside the container body 3 is further increased. When this pressure is applied to the entire bag 10, the contents are pushed out from the spout 2 of the bag 10.

  After a necessary amount of content has been poured out from the spout 2 of the bag 10, the cap 22 is screwed onto the tip of the spout 10 and attached, and the force applied to the body of the container body 3 is relaxed. When the external force applied to the container body 3 disappears, the deformed shape of the container body 3 is restored to the original state. When the shape is restored, the volume inside the container body 3 also returns to the original size. However, the volume of the bag 10 is reduced by the amount of use of the contents, and the internal space of the container body 3 is widened by the reduced volume. That is, the pressure in the internal space of the container body 3 is lower than the outside atmospheric pressure. The sheet-like member 41 of the valve 4 receives a force in a direction away from the inner wall of the container body 3 due to a pressure difference between the inside and the outside of the container body 3 as represented by the size of the arrow in FIG. When the sheet-like member 41 is separated from the inner wall, the vent 6 is opened and air is introduced from the outside to the inside of the container body 3. Thereby, the negative pressure inside the container main body 3 is released, and the pressure inside and outside becomes equal.

  As described above, according to the bag storage container according to the present embodiment, the spout 2 of the bag 10 from the spout outlet hole 5 of the container main body 3 while the main body of the bag 10 is stored inside the container main body 3. Can be drawn out and the contents can be poured out from the spout 2 of the bag 10. Thus, by accommodating the bag 10 in the container main body 3, the handling becomes easier as compared with the case of using the soft bag 10 as it is. Moreover, since the content can be poured out from the spout 2 of the bag 10, the troublesome operation | work which transfers a content from a bag to a dedicated container like the conventional one becomes unnecessary.

  Furthermore, according to the bag container according to the present embodiment, since the contents are poured out while the contents are put in the flexible bag 10, the bag 10 is shrunk when the contents are used. Thus, the volume is reduced, and the amount of air flowing into the bag 10 can be suppressed to a very small amount. That is, it is possible to make it difficult to bring the contents into contact with air, compared to the case where the contents are transferred to a relatively rigid container. Thereby, chemical reaction (oxidation etc.) with the contents and air and evaporation of the components of the contents can be made difficult to occur.

  Further, according to the bag container according to the present embodiment, when the container body 3 is pushed from the outside to increase the internal pressure, the vent 6 is closed by the valve 4, the internal sealed state is maintained, and the contents of the bag 10 are maintained. An object is pushed out from the spout 2. Therefore, the contents of the bag 10 can be surely poured out with a simple configuration that does not use a pump or the like. Further, since the force can be applied evenly to the entire bag 10 by air pressure simply by pushing the container body 3 with a finger or the like, the contents of the bag 10 can be used up to the end with a simple operation.

  Moreover, according to the bag container according to the present embodiment, when the external force applied to the container main body 3 is loosened, the container main body 3 is restored to its original shape, and the valve 4 is opened and the container main body 3 is opened from the vent hole 6. Air flows inside and the internal negative pressure is released. Thus, since the negative pressure inside the container body 3 is released, it is possible to effectively suppress the bag 10 from inflating due to the negative pressure and flowing in air from the spout 2.

  Moreover, according to the bag storage container which concerns on this embodiment, by unifying the shape of the container main body 3, several types of exclusive containers are not mixed, and efficient accommodation becomes possible.

The present invention is not limited to the embodiment described above.
That is, those skilled in the art may make various modifications, combinations, subcombinations, and alternatives regarding the components of the above-described embodiments within the technical scope of the present invention or an equivalent scope thereof.

  For example, in the above-described embodiment, an example in which a part of the sheet-like member 41 is fixed to the inner wall of the container body 3 by the fixing member 42 is described, but the present invention is not limited to this. In another embodiment of the present invention, an adhesive or the like may be applied to the back surface of the rectangular portion of the sheet-like member 41 to adhere to the inner wall of the container body 3.

  Moreover, the shape and structure of each part (the container main body 3, the valve 4, the spout outlet hole 5, the vent hole 6, etc.) shown in the above-described embodiment are merely examples, and the present invention has various other shapes and structures. Also included is a bag container having
