Description

The present invention relates to a pouch pack holder and a pouch pack installed in such a holder.

Conventionally, a pouch pack containing shampoo, liquid detergent, cosmetics, etc. (hereinafter, these are collectively referred to as contents) is known. Since the pouch pack can be manufactured at low cost, it is convenient as a disposable container and is used as a refill for the main body container. That is, after the contents of the main body container such as a plastic bottle are used up, the user purchases a pouch pack containing the contents for refilling and performs the refilling work of the contents.

By the way, since the pouch pack has flexibility and can wither as the contents are poured out, it is possible to use a pump having an airless function when taking out the contents. Therefore, such a pouch pack can be used not for refilling as described above, but for refilling with a pump. In this case, it is necessary to attach a spout (also called a spout) for attaching the pump to the pouch pack in advance, and the pouch pack shrinks as the contents are poured. Therefore, a pouch pack holder for stably holding such a pouch pack is required.

As the holder for the pouch pack, for example, a holder having a frame structure as disclosed in Patent Documents 1 and 2 is known. Since these frame structures are self-supporting with the pouch pack sandwiched between them, the contents can be poured out to maintain the self-supporting state even if the pouch pack shrinks, and pouring can be performed without the pouch pack falling over. Is possible.

Hereinafter, embodiments of the present invention will be described.
FIG. 1 is a perspective view showing a first embodiment of a pouch pack holder (hereinafter referred to as a holder) according to the present invention. The holder 1 includes a holding body 10 and an opening / closing body 20 that is opened and closed with respect to the holding body via a hinge portion 11. In the present embodiment, the self-three-dimensional pouch pack 100 as shown in FIG. Is configured to have a substantially rectangular parallelepiped shape including a front surface portion 1A, a rear surface portion 1B, an upper surface portion 1C, left and right side surface portions 1D, and a lower surface portion 1E so that the pouch pack can be stored inside (the pouch pack is not exposed).

In this case, the front surface portion 1A and the front surface side half of the upper surface portion 1C are composed of the opening / closing body 20. Further, the rear surface portion 1B, the rear surface side half of the upper surface portion 1C, the left and right side surface portions 1D, and the lower surface portion 1E are composed of the holding body 10, and the left and right side surface portions 1D have a shape in which the lower side is wider than the upper side. I have. The hinge portion 11 is provided on the front surface side at the lower ends of the left and right side surface portions of the holding body 10, whereby the opening / closing body 20 is opened and closed in the front-rear direction with respect to the holding body 10. (See FIGS. 6 and 7). That is, the opening / closing body 20 can be separated and joined to the holding body 10 by being opened / closed, and a storage space for holding the pouch pack 100 in a closed state with the holding body 10 is provided. Form.

A fixing port 1F for inserting and fixing the injection pump is provided in the central portion of the upper surface portion 1C. In the present embodiment, the fixing mouth portion 1F can be divided (separable and joined by opening / closing operation of the opening / closing body 20). Specifically, the fixing mouth portion 1F has a cylindrical shape, half of the cylindrical arc portion 12 is integrally formed with the holding body 10, and the other half of the cylindrical arc portion 22 is integrally formed with the opening / closing body 20. ing. Therefore, the holding body 10 and the opening / closing body 20 can be separated and joined in a state including the region of the fixing opening portion 1F (the division line L exists in the fixing opening portion).

The holding body 10 is formed with a holding portion 15 for holding the pouch pack to be inserted at a position below the cylindrical arc portion 12 (see FIG. 6). The holding portion 15 is associated with a spout provided on the pouch pack, and as will be described later, a recess formed in the spout is fitted into the holding portion 15 to fix the pouch pack (see FIG. 7). It is composed of members. When the pouch pack is held by the holding portion, the spout spout portion is located in the fixing port portion 1F of the holder, as will be described later.

FIG. 2 is a diagram showing an example of a pouring pump to which the cylindrical arc portions 12 and 22 are mounted and fixed to the integrated fixing port portion 1F. As will be described later, since the pouch pack has flexibility and shrinks with the pouring of the contents, the pouring pump 50 is an airless type that does not introduce air into the inside at the time of pouring. Be done. Since such an airless type pouring pump is generally known, a detailed structure thereof will be omitted, but a pressing portion 51 that is pressed against the urging force and a fixing port portion 1F A fixed portion 52 fixed to the pouch pack and a tubular portion 53 extending into the accommodating portion via the flow path of the spout of the pouch pack are provided, and by pressing the pressing portion 51, the contents in the pouch pack are released. , It is discharged from the discharge portion 55 formed in the pressing portion 51.

In the present embodiment, the injection pump 50 and the fixing port 1F are fixed by screwing. Therefore, male screw portions 12a and 22a are formed on the fixing port portion 1F (outer surface portions of the cylindrical arc portions 12 and 22 to be integrated), and are integrated inside the fixing portion 52. A female threaded portion 52a to be screwed into the male threaded portion is formed (see FIG. 8). In addition to screwing, the fixing method of both may be performed by press fitting or the like.

The materials of the holding body 10 and the opening / closing body 20 constituting the holder 1 are not particularly limited, but can be molded from plastic. By making it a plastic molded product, it can be manufactured at low cost, and it is possible to easily form an appearance design (diamond-shaped openings 30 formed in large numbers on the front surface portion 1A and the rear surface portion 1B) as shown in the figure. Is. By forming a large number of the openings 30 or forming a large opening, the design can be improved and the pouch pack housed inside can be visually recognized from the outside. Further, as shown in the holder 2 according to the third embodiment described later, the design can be improved by bending the left and right side surface portions 1D to give an overall rounded appearance design.

Of course, the constituent materials of the holder 1 are not limited, and may be formed of metal, wood, or the like if a high-class feeling is desired, for example, when storing a pouch pack as cosmetics. , May be partially framed.

FIG. 3 is a perspective view showing a configuration example of a pouch pack that can be attached to the holder shown in FIG. 1, and FIG. 4 is a diagram showing a configuration example of a spout attached to the pouch pack shown in FIG. be.
The pouch pack 100 of the present invention is configured not as a refill type but as a replacement type for the holder 1, and in the present embodiment, the periphery of the stacked rectangular synthetic resin sheet-like members 102a and 102b is welded. It is formed by doing so, and various contents can be accommodated inside it depending on the purpose. For this reason, the pouch pack 100 has a structure that is flexible so as to shrink as the contents are poured out, and can be discarded as it is after it is used up.

The pouch pack 100 of the present embodiment has a self-standing bag structure provided with a bottom 103, and a spout 200 made of a synthetic resin capable of pouring the contents is provided on the upper end edge thereof. The spout 200 is integrated with a welded portion 201 having a substantially boat-shaped cross section so as to be interposed between the sheet-shaped members 102a and 102b and welded, and a flow through which the contents pass. It is provided with a cylindrical spout portion 204 in which the path 203 is formed. The pouch pack 100 may have a so-called gusset body structure having gussets on the left and right side surface portions. In that case, even when the contents are poured out and the accommodating portion is withered, the sheet-shaped members 102a and 102b are difficult to adhere to each other due to the gussets on the left and right side surface portions, and the flow path of the contents can be easily secured.

A male screw portion 205 is formed on the outer peripheral surface of the spout portion 204, and a cap 210 having a female screw portion formed in this portion is screwed and mounted. Further, a recess 215 is formed on the outer peripheral surface of the spout portion 204 so that the holding portion 15 formed in the holding body 10 constituting the holder 1 described above can be fitted. The recess is formed by a pair of disk-shaped flanges 215a formed on the outer peripheral surface of the spout portion 204.

Further, a cylindrical inner plug 220 as shown in FIG. 5 is mounted in the flow path 203 of the spout. The inner plug 220 is provided with a thin film portion 221 that can be opened when the tubular portion 53 of the dispensing pump 50 shown in FIG. 2 is inserted. The thin film portion 221 may be formed by, for example, covering the opening portion with a film-like sheet, or may be integrally formed together with the inner plug.

The inner plug 220 is configured to remain in the flow path 203 with the cap 210 removed from the spout. Therefore, the inner plug 220 is press-fitted into the flow path with an outer diameter substantially the same as the diameter of the flow path 203, and a flange 223 that abuts on the upper end edge 206 of the spout portion 204 is integrally formed at the upper end portion. Has been done. That is, the inner plug 220 is press-fitted into the flow path 203 until the flange 223 abuts on the upper end edge 206, and then the cap 210 is attached. Since it remains inside, the contents are prevented from spilling when the pouch pack is attached to the holder.

Further, by providing the inner plug 220 as described above, it is not necessary to form a leak-preventing thin film portion in the flow path 203 in advance, and the contents can be filled from the spout portion. In this case, it is preferable that the cap 210 and the inner plug 220 are integrated when they are attached to the spout, and by integrating them, the handleability can be improved. For example, the cap 210 and the inner plug 220 are connected so as to be easily separated, and the inner plug can be rotated on the outer surface of the inner plug 220 and the inner surface of the flow path 203 in the tightening direction of the cap 210. In the opening direction of the cap, it is sufficient to provide an engaging relationship of unevenness that prevents the rotation of the inner plug. In such a configuration, after filling the contents, the inner plug 220 can be attached by tightening the cap 210 while inserting the inner plug 220 into the flow path 203, and even if the cap is removed during use by the user, the inner plug 220 flows. It will remain in the road 203.

Next, the method of using the holder 1 described above will be described with reference to FIGS. 6 to 9.
As shown in FIG. 6, the opening / closing body 20 is opened with respect to the holding body 10, and the cap 210 of the pouch pack containing the contents is opened. Even if the cap 210 is opened, as described above, since the inner plug 220 is fitted in the flow path of the spout, the contents are prevented from spilling.

The pouch pack 100 with the cap 210 opened is installed at a predetermined position of the holding body 10 by fitting the recess 215 formed on the outer peripheral surface of the mouth portion 204 into the holding body 15 formed on the holding body 10. (See FIG. 7). In this case, since the storage area is greatly opened due to the opening / closing body 20, the pouch pack 100 can be easily installed, and in particular, the spout portion is picked up and held by the holding portion 15. , Installation work can be done easily. Further, since the area of the fixing mouth portion 1F is also open, the installation can be performed more easily. In the installed state of the pouch pack 100, the spout spout port 204 is located in the fixing port 1F on the holder side, so that the pouch pack is stably stored and held.

The opening / closing body 20 is closed with respect to the holding body 10 in a state where the pouch pack 100 is installed at a predetermined position and stored. When the opening / closing body 20 is closed with respect to the holding body 10, a fixing mouth portion 1F in which the cylindrical arc portions 12 and 22 are integrated is formed on the upper surface portion thereof. Then, the pouring pump 50 is fixed to the fixing port 1F by screwing the fixing portion 52 of the pouring pump 50 into the fixing port 1F (see FIGS. 8 and 9). By tightening the fixing portion 52 to enter the fixed state, the tip portion 53a of the cylinder portion 53 of the dispensing pump 50 breaks the thin film portion 221 of the inner plug 220, whereby the contents are poured through the cylinder portion 53. It will be possible to get out.

In the present embodiment, by fixing the pouring pump 50 to the fixing port 1F, the opening / closing body 20 does not inadvertently open with respect to the holding body 10, so that the pouch pack is stably stored and held. be able to. Further, since the pouch pack 100 is housed in the holder in the closed state and is not exposed to the outside, the appearance can be improved. Further, since the pouch pack 100 shrinks with the pouring of the contents, it is not necessary to provide a structure for introducing air into the pouring pump 50, and therefore, the anaerobic contents are accommodated and used. be able to. That is, since the contents do not come into contact with air, it is possible to prevent oxidation.

Next, another embodiment of the present invention will be described. In the following embodiments, the same components as those in the above-described embodiments are designated by the same reference numerals, and detailed description thereof will be omitted.
FIG. 10 is a diagram showing a second embodiment of the holder.
In the first embodiment, the hinge portion 11 is provided on the front surface side at the lower ends of the left and right side surface portions of the holding body 10 so that the opening / closing body 20 can be opened / closed in the front-rear direction. It is also possible to configure the opening / closing body 20 to open in the left-right direction. In this case, the opening / closing body 20 is in a state of being opened including the fixing mouth portion 1F as in the above embodiment, so that the pouch pack can be easily stored and installed. As described above, the opening / closing direction of the opening / closing body can be appropriately deformed.

11 to 12 are views showing a third embodiment (holder 2) of the holder. FIG. 11 shows a state in which the opening / closing body 20 is closed, and FIG. 12 shows a state in which the opening / closing body 20 is opened.
In the holder 1 according to the first and second embodiments shown in FIGS. 1 and 10, a fixing port portion 1F (integrated cylindrical arc portions 12 and 22) for inserting and fixing the pouring pump is inserted. An outer surface portion) is provided, and the male screw portions 12a and 22a formed on the fixing port portion 1F are screwed into the female screw portion 52a of the fixing portion 52 of the dispensing pump 50 to dispense with the holder 1. Although the pump 50 was fixed (see FIGS. 8 and 9), the holder 2 according to the present embodiment is not provided with the fixing port 1F.

The holder 2 includes an insertion port 2F into which the spout 200 spout port 204 is inserted instead of the fixing port 1F. As shown in FIG. 12, the insertion opening 2F has a cylindrical shape, and half of the cylindrical arc portion 12A is integrally formed with the holding body 10 and the other half of the cylindrical arc portion 22A is integrally formed with the opening / closing body 20. It can be separated and joined by opening and closing the opening / closing body 20.

Male screw portions 12a and 22a provided on the outer peripheral surface of the fixing opening portion 1F are not formed on the insertion opening portion 2F, and the lengths of the cylindrical portions of the cylindrical arc portions 12A and 22A are formed to be short. Has been done. As a result, when the pouch pack 100 is held by the holding portion 15 of the holder 2, the root side of the spout portion 204 of the pouch pack 100 (the recess 215 side of the spout portion 204 into which the holding portion 15 of the holder 2 fits). ) Is located in the insertion opening 2F, the tip side of the spout portion 204 protrudes from the insertion opening 2F, and the male screw portion 205 formed on the outer peripheral surface of the protruding tip side is exposed.

By screwing the exposed male threaded portion 205 and the female threaded portion 52a of the pouring pump 50, the pouring pump 50 is fixed to the spout 200 instead of the holder 2 (see FIG. 15). Since the male screw portion 205 of the spout 200 is usually formed for mounting the cap 210, the male screw portion 52a of the pouring pump 50 is designed so as to be screwed to the male screw portion 205. The screw portion 205 can be used for both mounting the cap 210 and fixing the pouring pump 50, and the pouring pump 50 can be easily fixed to the spout 200.

By connecting and fixing the pouring pump 50 to the spout 200 in this way, the possibility that the contents leak into the holder 2 can be eliminated. Since the pouring pump 50 and the spout 200 are screwed together, it is surely prevented that the contents leak to the inside of the cylindrical arc portions 12A and 22A of the holder 2.

Further, since the holder 2 according to the present embodiment does not need to form the male screw portions 12a and 22a on the cylindrical arc portions 12A and 22A, it is not necessary to worry about the damage thereof, which is advantageous in terms of durability.

Next, another embodiment of the pouch pack according to the present invention (pouch pack 300) will be described with reference to FIGS. 13 to 15. The above-mentioned pouch pack 100 is premised on using an airless type as the pouring pump 50, but the pouch pack 300 according to the present embodiment includes an inner plug 320 that closes the air inlet of the pouring pump. Therefore, it can be used in combination with a non-airless type (a type that introduces air into the inside at the time of pouring) pouring pump 60. The details of the inner plug 320 will be described later.

FIG. 13 shows an example of a pouring pump 60 of a type that introduces air. Similar to the dispensing pump 50 shown in FIG. 8 and the like, the dispensing pump 60 has a pressing portion 51 that is pressed against the urging force and a fixing port portion 1F or FIG. 11 shown in FIG. It is provided with a fixing portion 52 fixed to the spout portion 204 of the spout 200 and a tubular portion 53 extending into the accommodating portion through the flow path of the spout of the pouch pack, and is different from the pouring pump 50. , The side surface of the tubular portion 53 has an opening 53b which is an air introduction port. This type of pouring pump is widely used for bottle-shaped containers, because it increases the internal pressure of the container and dispenses the contents by introducing air into the container of the bottle-shaped container at the time of pouring. It is common to have an air inlet.

Further, in the present embodiment, the thin film portion 221 of the inner plug 220 shown in FIG. 8 and the thin film portion 321 of the inner plug 320 shown in FIG. 14 are more easily attached to the tip portion 53a of the tubular portion 53 of the pouring pump 60. A rod-shaped auxiliary portion 53d having a tapered tip is provided so that the tip can be penetrated. Since the auxiliary portion 53d is not provided in a general-purpose product of a pouring pump of a type that introduces air widely used in a bottle-shaped container or the like, it is preferable to form the auxiliary portion 53d so as to be detachable from the tip portion 53a. By attaching the auxiliary portion 53d to the tip portion 53a of the general-purpose product, the dispensing pump 60 provided with the auxiliary portion 53d as shown in FIG. 13 can be easily manufactured.

Next, the inner plug 320 attached to the pouch pack 300 will be described in detail with reference to FIGS. 14 to 15. FIG. 14 shows the inner plug 320 of the pouch pack 300 in a state where the pouch pack 300 is installed in the holder 2 according to the third embodiment, and shows the insertion direction of the pouring pump 60 shown in FIG. It is a perspective view. Further, FIG. 15 is a cross-sectional view showing a state in which the pouch pack 300 is installed in the holder 2 according to the third embodiment, and the pouring pump 60 is inserted and fixed.

As shown in FIG. 15, when the pouring pump 60 and the spout 200 are screwed and fixed, the insertion port 2F of the holder 2 is the fixing portion 52 of the pouring pump 60 and the spout portion 204 of the spout 200. It is sandwiched and fixed between. As a result, the opening / closing body 20 can be locked so that the opening / closing body 20 of the holder 2 does not inadvertently open with respect to the holding body 10.

As shown in FIG. 14, the inner plug 320 has a bowl-shaped shape, and a thin film portion 321 that can be opened when the cylinder portion 53 of the pouring pump is inserted is provided at the bottom thereof. Similar to the thin film portion 221 of the inner plug 220, the thin film portion 321 may be formed by, for example, covering the opening portion with a film-like sheet, or may be integrally formed together with the inner plug.

As shown in FIG. 15, the side wall of the inner plug 320 is formed so as to close the opening 53b of the pouring pump 60 when the pouring pump 60 is mounted. For example, the inner plug 320 is preferably formed by using a flexible material, and its side wall is designed to be in close contact with the outer surface of the tubular portion 53 to close the opening 53b.

As a result, the pouch pack 300 can be used in combination with a general pouring pump 60 having an opening 53b. That is, by blocking the introduction of air from the opening 53b by the inner plug 320, the pouch pack 300 can be made to wither with the pouring of the contents, and the oxidation of the contents can be prevented. Will be.

Further, the inner plug 320 is preferably configured so as to remain in the flow path 203 of the spout 200 with the cap 210 removed from the spout 200, similarly to the inner plug 220 shown in FIG. It is possible to prevent leakage of the contents. That is, since the inner plug 320 has the same effect as the inner plug 220 in preventing the leakage of the contents and further closing the opening 53b of the pouring pump 60, the pouch pack 300 provided with such a middle plug 320 According to this, not only the type in which the injection pump introduces air (injection pump 60) but also the above-mentioned airless type (injection pump 50) can be used.

The inner plug 320 may be provided on the pouring pump 60 side instead of the pouch pack 300. In that case, the pouring pump 60 is provided with the inner plug 320 in a state of penetrating the thin film portion 321. By inserting and fixing the pouring pump 60 into the spout 200, air is introduced as in FIG. The type of dispensing pump 60 can be put into an airless type state.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be variously modified and implemented without departing from the gist thereof.

For example, the shape and size of the pouch pack, the mounting position of the spout, and the like can be appropriately deformed, and the shape and size of the holder can be appropriately deformed accordingly. The installation position and engagement method of the holding portion 15 provided on the holding body 10 are not particularly limited, and can be appropriately deformed.
