Description

The present invention relates to a packaging bag case and a packaging bag case, and in particular, a packaging bag case for a packaging bag containing a fragrance, a deodorant and other contents, and a fragrance, a deodorant and the like. The present invention relates to a case containing a packaging bag containing a packaging bag containing contents.

For example, substances that the active ingredient evaporates and diffuses to the outside, such as fragrances, and substances that adsorb odorous components in the outside air, such as deodorants, are used in a form in which they are housed inside the packaging container. It is common.

Since such a packaging container is used by being deferred at a certain indoor position for a long period of time, it is often composed of a molded container having high form stability and high barrier properties (for example, Patent Document 1). . In a packaging container composed of a molded container, a hole is provided on one wall surface thereof, and air inside the packaging container and external air can enter and exit through the hole.

For example, in the case of a horizontal packaging container, such a hole for ventilation is generally openable on the upper surface, and is opened in the following procedure. That is, the container upper surface is removed by attaching a peelable film to the upper surface of the molded container and shipping the container in a sealed state, and removing a predetermined portion of the container upper surface by the adhesive strength of the film when peeling the film during use. Open a hole for ventilation.

Such a packaging container is often used by being attached to a dedicated case. For example, by mounting a horizontal packaging container having a hole for ventilation on the top surface on the case, the surface provided with the hole can be placed on the front and placed vertically. Thus, it becomes possible to reduce the mounting area of the container by changing the horizontally placed packaging container to the vertically placed container.

However, in the conventional packaging container, even if a plurality of holes are provided on one surface, the air flow direction between the internal space and the outside is the same in both holes and is limited. There is little going in and out. For this reason, even if a fragrance | flavor and a deodorant are accommodated in the container, a fragrance effect and a deodorant effect cannot fully be exhibited.

In addition, in order to absorb the off-flavor in the target room and produce a fragrance effect, a fragrance and a deodorant may be mixed in the packaging container. In this case, since the conventional packaging container has low air permeability, there is a possibility that the scent emitted from the fragrance is not sufficiently discharged outside and is absorbed by the deodorant. For this reason, not only cannot the fragrance effect be exhibited, but also the deodorant that absorbs the fragrance from the fragrance cannot absorb the external odor, so that it is difficult to exert the deodorization effect. Furthermore, since the deodorant absorbs a strong fragrance from the fragrance, the absorption performance is likely to deteriorate early.

Then, an object of this invention is to provide the case for packaging bags with the high air permeability with the inside of a case and the inside of the packaging bag accommodated in a case, and the exterior. Moreover, the objective of this invention is providing the case for packaging bags which can fully exhibit fragrance performance and deodorizing performance simultaneously.

In order to solve the above-mentioned problems, a packaging bag case of the present invention is a packaging bag case for housing a packaging bag having a plurality of holes communicating with the inside, and has ventilation openings on opposite sides. parts are formed respectively, the front and rear is characterized Rukoto comprises a flat shape.

The packaging bag-containing case of the present invention includes a packaging bag in which a plurality of holes leading to the inside are formed, and any of the above-described packaging bag cases that accommodate the packaging bag, and at least one of the packaging bags. A plurality of holes are formed by peeling the outer layer material on one surface.

In the packaging bag-containing case of the present invention, it is preferable that the plurality of holes of the packaging bag do not face the opening for ventilation of the packaging bag case.

ADVANTAGE OF THE INVENTION According to this invention, the case for packaging bags with high air permeability with the inside of a case and the inside of the packaging bag accommodated in a case and the exterior is realizable. Moreover, the case for packaging bags which can fully exhibit aroma performance and deodorizing performance simultaneously can be provided.

Hereinafter, a packaging bag case according to an embodiment of the present invention will be described in detail with reference to the drawings. This embodiment shows an embodiment when the present invention is applied to a case for a vertical packaging bag that houses a self-supporting packaging bag, but the present invention is not limited to this embodiment, The present invention can also be applied to cases where packaging bags that are not self-supporting are accommodated, or cases for horizontal packaging bags.

FIG. 1 is a perspective view of a configuration of a packaging bag case 110 and a packaging bag 10 to be accommodated according to the present embodiment as viewed from the front side. FIG. 2 is a side view of the packaging bag case 110 as viewed from the left side. FIG. 3 is a side view of the packaging bag case 110 viewed from the right side. FIG. 4 is a partial cross-sectional view in the thickness direction showing the layer structure of the trunk film 20. FIG. 5 is a partial cross-sectional view in the thickness direction showing the layer structure of the body film 20, and is a view showing a process of peeling the outer layer material 30. FIG. 6 is a top view of the packaging bag case 110 in a state in which the packaging bag 10 is accommodated. FIG. 7 is a partially enlarged view of a cross section orthogonal to the height direction of the packaging bag case 110.

The packaging bag case 110 has a vertically placed hollow shape in which the front surface 122 and the back surface 123 extend upward from the bottom surface 121 and reach the upper opening 130. Each of the front surface 122 and the back surface 123 has a curved shape that swells outward as the distance from the side portions 125 and 126 of the packaging bag case 110 increases, that is, toward the center in the width direction of the packaging bag case 110.

The packaging bag case 110 has a flat shape in which the front surface 122 and the back surface 123 are wide, and has an internal space surrounded by the bottom surface 121, the front surface 122, and the back surface 123.

Note that the front surface 122 and the back surface 123 may be the same or not symmetrical.

The packaging bag case 110 has ventilation openings 131 and 132 formed on left and right side portions 125 and 126 facing each other. Accordingly, the openings 131 and 132 are formed so as to face each other, and the air permeability between the internal space of the packaging bag case 110 and the outside is enhanced.

Here, the openings 131 and 132 can have any shape and number depending on the design, strength, and other conditions of the packaging bag case 110.

In addition, it is preferable to form an opening in one or both of the front surface 122 and the back surface 123 because air permeability between the internal space of the packaging bag case 110 and the outside can be improved. Also, the openings provided in the front surface 122 and the back surface 123 can be of any shape and number depending on the design, strength, and other conditions of the packaging bag case 110.

The upper portion of the packaging bag case 110 is preferably provided with an upper surface opening 130 because air permeability between the internal space and the outside can be improved, but it can also be a wall surface without an opening.

The packaging bag case 110 is formed of a thermoplastic resin.
As the thermoplastic resin, for example, an olefin resin such as polyethylene or polypropylene, a polystyrene resin, or the like can be used. It is preferable to add a plant filler in terms of aroma and texture.

As the plant filler, for example, wood powder such as hinoki and cedar can be used. Not only new wood, but also waste wood such as sawdust and bark produced as a by-product during thinning and lumbering can be used. Similarly, bamboo, tea husk, coffee bean pomace, pulp and the like can also be used as raw materials, and are used after being pulverized. These vegetable fillers have a particle size of 500 μm or less, preferably about 100 to 300 μm, and are used by blending 30 to 80% by weight, preferably 50 to 70% by weight with a thermoplastic resin.

Furthermore, it is preferable to impregnate the plant material with a fragrance. In particular, when a fragrance is imparted to the packaging case, the functions of both the fragrance and the deodorant can be sufficiently exerted by separating the functions of the packaging bag to be contained as a deodorant and a deodorant. it can.

The packaging bag case 110 can be formed by a known manufacturing method such as injection molding or compression molding, and may be integrally formed, or may have a divided structure such as front-rear division or left-right division.

The openings 131 and 132 may be formed at the same time during injection molding or the like, or may be formed by post-processing, but in any case, the directions in which the openings 131 and 132 face each other (as indicated by the arrows in FIG. 7). (Direction) is preferably formed so as to penetrate therethrough.

When molding by injection molding or the like, a thermoplastic resin skin layer is formed on the molding surface, and exposure of the plant filler to the surface of the packaging bag case 110 is suppressed, so that the fragrance from the plant filler is sufficient. May not be done. Therefore, when it is desired to enhance the fragrance action from the packaging bag case 110, it is preferable to slightly scrape the surface of the packaging bag case (several μm to several hundreds μm). When the contents of the packaging bag to be stored are deodorizers or the like, only the outer surface side of the packaging bag case may be scraped off.

On the front surface 122 of the packaging bag case 110, drug holding portions 111, 112, and 113 for holding drugs are formed. Each of the medicine holding portions 111, 112, and 113 is a bottomed hole formed inward from the upper end of the front surface 122, and may be processed after the packaging bag case 110 is formed. The medicine to be held is, for example, a liquid or solid fragrance or deodorant. If such medicine can be held, the shape and position of the medicine holding portion can be arbitrarily set.

When a liquid fragrance such as a fragrance extracted oil is used as the medicine, the fragrance held in the medicine holders 111, 112, 113 is directly diffused from the upper opening, and the packaging bag case 110 is used. It penetrates into the interior and is adsorbed especially by the vegetable filler, and finally released gently from the entire front surface 122, and a long-term aroma effect can be obtained. The opening may be properly plugged.

The packaging bag 10 accommodated in the packaging bag case 110 is a standing pouch having a plurality of holes 61, 62, 63, 64, 65, 66 that communicate with the inside. The packaging bag 10 includes a body film 20 and a bottom film 70.

The body film 20 is obtained by heat-sealing the left and right end portions 20b and 20c and the upper end portion 20d with two films facing each other. The bottom film 70 is inserted into the lower portion 20 a of the trunk film 20 in a folded state, and is heat-sealed to the trunk film 20.

With such a configuration, the packaging bag 10 includes an internal space surrounded by the two films of the body film 20 and the bottom film 70, and a deodorant, a fragrance, a deodorant, a hygroscopic agent, Contains insect repellent and other contents.

Examples of materials used for the body film 20 and the bottom film 70 include low density, medium density, or high density polyethylene, linear low density polyethylene, isotactic polypropylene, propylene / ethylene copolymer, and polybutene-1. , Ethylene / propylene copolymer, ethylene / butene-1 copolymer, propylene / butene-1 copolymer, ethylene / vinyl acetate copolymer, ion-crosslinked olefin copolymer (ionomer), poly-4-methylpentene- 1. Maleic anhydride modified polyethylene, maleic anhydride modified polypropylene, ethylene-methacrylic acid copolymer, ethylene-acrylic acid copolymer, and other thermoplastics such as ethylene propylene rubber (EPR) and ethylene propylene diene rubber (EPDM) Elastomers, and these alone Or as a mixture can be used those used two or more kinds.

The trunk | drum film 20 is the laminated material formed by laminating | stacking the outer layer material 30, the peeling layer 40, and the inner layer material 50 in order from the outer side. In the inner layer material 50, half cuts corresponding to the plurality of hole portions 61, 62, 63, 64, 65, 66 are formed.

The inner layer material 50 is made of, for example, a thermoplastic resin that can be thermally bonded. As the peeling layer 40, for example, an acrylic resin, a polyamide resin, a silicone resin, a vinyl resin, a urethane resin, an epoxy resin, or the like is used alone or in combination, and the inner layer material 50 and the outer layer material 30 are bonded in a peelable state. . As the outer layer material 30, for example, a thermoplastic film, a stretched film, a metal foil or the like is used.

4 is a cross-sectional view of the half-cut 56 corresponding to the hole 61, and FIG. 5 shows the process of peeling the outer layer material 30 to form the hole 61. The other holes 62, 63 are shown in FIG. , 64, 65, 66 are formed in the same manner. That is, when the user peels the outer layer material 30 from the inner layer material 50 against the adhesive force of the release layer 40, the peeled portion 58 surrounded by the half cut 56 is formed by the adhesive force of the release layer 40. It is pulled away from 50 and the hole 61 is formed (FIG. 5).

The plurality of holes 61, 62, 63, 64, 65, 66 are disposed on the front surface 22 of the body film 20. In a state where the bottom film 70 is spread and the packaging bag 10 is self-supporting, the front surface 22 is curved. That is, it has a shape that spreads outward as it moves away from the left end 20b and the right end 20c, and has a shape that spreads outward as it goes from the upper end 20d to the lower portion 20a.

Since the front surface 22 has such a curved surface, in the left-right direction, the holes 61 and 64 provided on the left end 20b side of the body film 20 face slightly to the left from the front, and on the right end 20c side. The provided holes 63 and 66 face slightly to the right from the front. However, they do not face each other in alignment with the positions of the openings 131 and 132. With such a configuration, the fragrance component does not rise directly from the hole, but can be diffused gently by ventilation from the opening.

Moreover, about the up-down direction, the hole parts 61, 62, and 63 provided in the upper end part 20d side of the trunk | drum film 20 have faced the upper side slightly from the front.

The packaging bag of the present invention can be applied to pouches other than the self-supporting type as long as a hole is provided on at least one surface. Moreover, it is preferable that a packaging bag is a form provided with the softness | flexibility.

The packaging bag 10 having the above configuration is accommodated in a packaging bag case 110 and used as a packaging bag-containing case 100.

Since it was comprised as mentioned above, according to the case 110 for packaging bags of the said embodiment, the air permeability between the inside of a case and the inside of the packaging bag accommodated in a case, and the exterior can be improved. . For this reason, the deodorant, the fragrance, the deodorant, the moisture absorbent, the insect repellent and other contents contained in the packaging bag 10 absorb the predetermined component of the outside air or easily emit the predetermined component to the outside air. It is possible to enhance the effect of the contents.

In addition, by including a vegetable filler in the packaging bag case 110, the case itself can have aroma performance. Furthermore, if a deodorant is accommodated in the packaging bag 10, it becomes possible to emit a fragrance from a case, absorbing the bad odor in external air.

Next, a modification of the above embodiment will be described.
The outer shape of the packaging bag case is not limited to the above-described shape, and can be, for example, the shape shown in FIGS.

FIG. 8 is a top view of the packaging bag case 210 according to the first modification in a state in which the packaging bag 10 is accommodated. FIG. 9 is a partially enlarged view of a cross section perpendicular to the height direction of the packaging bag case 210 according to the first modification.

The packaging bag case 210 has a rectangular parallelepiped shape with an upper surface being an opening. That is, the vertical cross section is rectangular. The front surface 222 and the back surface 223 are flat plates parallel to each other, and side surfaces 225 and 226 (side portions) which are flat plates parallel to each other are arranged at both ends thereof. Openings are formed on the side surfaces 225 and 226 in the same manner as the openings 131 and 132 of the packaging bag case 110. It is preferable that the openings formed in the side surfaces 225 and 226 are formed so as to penetrate along the opposing directions (the directions of arrows in FIG. 9).

When the packaging bag 10 is accommodated in the packaging bag case 210 having such a shape, the gap between the inner surface of the packaging bag case 210 and the front surface 22 which is the outer surface of the packaging bag 10 is an opening formed in the side surfaces 225 and 226. Narrows away from the distance. For this reason, the flow path from one of the side surfaces 225 and 226 to the other is narrowed at the center in the width direction of the packaging bag case 210, so that the flow velocity changes due to the venturi effect, and the air permeability between the internal space and the outside air is increased. Further improve.

FIG. 10 is a top view of the packaging bag case 310 according to the second modification in a state where the packaging bag 10 is accommodated. FIG. 11 is a partially enlarged view of a cross section perpendicular to the height direction of the packaging bag case 310 according to the second modification.

In the packaging bag case 310, the front surface 322 and the back surface 323 have a curved shape that goes inward toward the center in the width direction of the packaging bag case 310. Side surfaces 325 and 326 (side portions), which are flat plates parallel to each other, are disposed at both ends of the front surface 322 and the back surface 323. Openings are formed on the side surfaces 325 and 326 in the same manner as the openings 131 and 132 of the packaging bag case 110. It is preferable that the openings formed in the side surfaces 325 and 326 are formed so as to penetrate along the opposite directions (the directions of the arrows in FIG. 11).

When the packaging bag 10 is accommodated in the packaging bag case 310 having such a shape, the gap between the inner surface of the packaging bag case 310 and the front surface 22 which is the outer surface of the packaging bag 10 is formed in the side surfaces 325 and 326. Narrows away from the distance. For this reason, the flow path from one side of the side surfaces 325 and 326 to the other becomes narrow at the center in the width direction of the packaging bag case 310. The change in the flow path width is larger than in the case of the packaging bag case 210 because the front surface 322 and the back surface 323 are curved surfaces. Therefore, the change in the flow velocity due to the venturi effect is also increased, and the air permeability between the internal space and the outside air is further improved as compared with the packaging bag case 110 of the above embodiment and the packaging bag case 210 of the first modification.

Although the packaging bag case 110 of the embodiment has a curved surface shape corresponding to the swelling of the packaging bag, there is a margin on both sides of the side seal portion of the packaging bag, and there is a slight Venturi effect. I can expect.

In addition, the shape of the front surface of a packaging bag case, a back surface, and a side surface (side part) can be made into shapes other than the shape shown in FIGS. 1-11, and a front surface and a back surface may be asymmetrical.

Moreover, it is preferable to arrange | position the member which shields the ventilation | gas_flowing to the packaging bag 10 side in the inner surface of the case 110 for packaging bags. As a member to be shielded, for example, a film-like polyethylene terephthalate is used, and is adhered and fixed to the inner surface of the front surface 122.

If comprised in this way, when a deodorant is accommodated in the packaging bag 10, for example, the fragrance from the case 110 for packaging bags will become difficult to be absorbed by a deodorant. As a result, the fragrance from the packaging bag case 110 is diffused to the outside, and the external odor is absorbed by the deodorant in the packaging bag 10 through the openings 131 and 132, thereby simultaneously exhibiting the fragrance effect and the deodorization effect. Further, the deodorant absorbs the fragrance from the packaging bag case 110, so that the deodorization performance is not lowered early.

Although the present invention has been described with reference to the above embodiment, the present invention is not limited to the above embodiment, and can be improved or changed within the scope of the purpose of the improvement or the idea of the present invention.

As described above, the packaging bag case according to the present invention is suitable for housing a packaging bag containing a deodorant and other contents.
