Description

The present invention relates to a wrapping mount for wrapping and accommodating the contents, and a wrapping container formed by using the wrapping mount.

Conventionally, products such as insect repellents and fragrances for the purpose of emitting odors and scents have been sold. Since these products are required to have airtightness and a sustained release function, they are often housed in a packaging container in a form called a blister pack. The blister pack is a container body having a concave body and a flat flange formed by thermoforming a plastic sheet according to the shape of the contents, and the opening of the container body is covered and bonded at the flange. In addition to insect repellents and fragrances, it is widely used in various packaging such as toiletries such as toothbrushes, stationery such as glue sticks and staples, and medical instruments such as injection needles. See 1 and 2).

Attempts have also been made to store objects that emit odors and scents in blister packs and commercialize them as insect repellents, fragrances, and the like. Packaging containers used for insect repellents and fragrances are required to be airtight and sustained release. Airtightness is a function that does not leak the internal gas to the outside, and sustained release is a function that gradually releases components emitted from the contents. However, in the conventional blister pack, when the flange portion of the container body is peeled off from the mount, the container body is ventilated at once and is not gradually ventilated, so there is a problem that the sustained release property is not sufficient. Further, since the blister pack is composed of a container body formed of a plastic sheet and a mount mainly made of a paper base material, there is a problem that the manufacturing process is complicated and the cost is high.

Therefore, it is an object of the present invention to provide a packaging mount and a packaging container that can be easily manufactured and can gradually release substances emitted from the contents.

<Composition of wrapping mount>
FIG. 1 is a front view of a packaging mount according to an embodiment of the present invention. FIG. 2 is a rear view of a packaging mount according to an embodiment of the present invention. FIG. 3 is a cross-sectional view taken along the line AA in FIG. FIG. 4 is a cross-sectional view taken along the line BB of FIG.

As shown in FIGS. 1 and 2, the packaging mount 20 has a substantially vertically symmetrical outer shape with respect to the planned folding line O. When the wrapping mount 20 is folded in two from the planned folding line O, the parts other than the picked portion 25 overlap at the upper part of the drawing and the lower part of the drawing from the planned folding line O. The wrapping mount 20 can be divided into a main body portion and a hanging portion in addition to being classified into a portion on the upper side of the drawing and a portion on the lower side of the drawing. The main body portion functions as an accommodating portion for accommodating the contents, and the hanging portion functions as a suspension portion for the entire packaging container. The upper portion of the drawing is divided into a main body portion 10a and a hanging portion 11a, and the lower portion of the drawing is divided into a main body portion 10b and a hanging portion 11b. Hereinafter, the main body portion 10a and the main body portion 10b may be collectively referred to as the main body portion 10, and the hanging portion 11a and the hanging portion 11b may be collectively referred to as the hanging portion 11. The main body portion 10a, the hanging portion 11a, the main body portion 10b, and the hanging portion 11b are all integrated, and are formed by punching out a mount composed of a plurality of layers.

The planned folding line O is a mountain fold from the state of FIG. 1 and a valley fold from the state of FIG. 2 when the packaging container is constructed. Therefore, after folding in two along the planned folding line O, the surface shown in FIG. 1 becomes the outer surface of the packaging container, and the surface shown in FIG. 2 becomes the inner surface of the packaging container. In the present embodiment, the outer surface of the packaging container shown in FIG. 1 will be referred to as the first surface 20a, and the inner surface of the packaging container shown in FIG. 2 will be referred to as the second surface 20b. The notation of the first surface and the second surface is for convenience to distinguish between the two, and which may be the first surface and which may be the second surface. In the present embodiment, the planned fold line O is formed as a fold groove, but may have a form other than the fold groove, or may not be processed at all. Even if the planned folding line O is not specifically processed, the middle part from the end of the hanging portion 11a of the packaging mount 20 to the end of the hanging portion 11b is assumed to be the planned folding line O. In the examples shown in FIGS. 1 and 2, the recessed portion is the position of the planned folding line O as compared with the portion having the maximum width in the left-right direction.

FIG. 3 is a cross-sectional view taken along the line AA of FIG. FIG. 4 is a cross-sectional view taken along the line BB of FIG. The wrapping mount 20 has a protective layer 35 on the first surface 20a side (upper side in FIG. 3 and left side in FIG. 4), which is the frontmost side. As shown in FIGS. 1 to 4, three ventilation holes 26 are formed in the main body portion 10a. As shown in FIGS. 3 and 4, the ventilation holes 26 penetrate the portion of the wrapping mount 20 other than the protective layer 35. Since the ventilation hole 26 is open on the second surface 20b side, the contour circle of the ventilation hole 26 is shown by a solid line in FIG. 2, but the first surface 20a side is covered with the protective layer 35. Therefore, the contour circle of the ventilation hole 26 is shown by the alternate long and short dash line. However, when the protective layer 35 is transparent, the ventilation holes 26 can be visually recognized from the first surface 20a side as well. The ventilation hole 26 is a hole for connecting the inner surface side and the outer surface of the packaging mount, which is the accommodating portion of the packaging container. In this embodiment, it has three ventilation holes 26.

The main body portion 10a is formed with first cuts 21a and 21b, third cuts 23a and 23b from the first surface 20a side, and second cuts 22 are formed from the second surface 20b side. Hereinafter, the first notch 21a and the first notch 21b may be collectively referred to as the first notch 21, and the third notch 23a and the third notch 23b may be collectively referred to as the third notch 23. As shown in FIGS. 1 to 3, the first notch 21 is a notch formed from the first surface 20a side and does not penetrate the packaging mount 20, a so-called half cut. Further, as shown in FIGS. 1 and 2, the third notch 23 is a notch formed from the first surface 20a side and does not penetrate the packaging mount 20, a so-called half cut. Therefore, the first cut 21 and the third cut 23 are shown by a solid line in FIG. 1, but are shown by a alternate long and short dash line in FIG. 2.

Further, as shown in FIGS. 1, 2, and 4, the second notch 22 is a notch formed from the second surface 20b side and does not penetrate the packaging mount 20, a so-called half cut. Therefore, the second notch 22 is shown by a solid line in FIG. 2, but is shown by a alternate long and short dash line in FIG. 1. Since FIGS. 3 and 4 mainly explain the relationship between the first notch 21, the second notch 22, the third notch 23, and the ventilation hole 26 in the cross section of the packaging mount 20, the packaging mount 20, the thickness of the protective layer 35, the depths of the first notch 21, the second notch 22, and the third notch 23 are exaggerated with respect to the surface direction of the packaging mount 20.

A total of four first notches 21 and third notches 23 are formed on the first surface 20a of the packaging mount 20 so as to surround all the ventilation holes 26. Of these, two first notches 21 are formed on the first surface 20a of the wrapping mount 20 so as to sandwich all the ventilation holes 26. The first notch 21a and the first notch 21b are parallel to each other and are formed so as to enter inward from the upper edge 12 of the main body portion 10a. The two first cuts 21a and 21b are formed up to the positions of the end points of the third cut 23a and the third cut 23b on the planned folding line O side, respectively.

Two first notches 21 are formed on the first surface 20a of the packaging mount 20 so as to extend in a direction intersecting the planned folding line O of the packaging mount 20. In the present embodiment, as shown in FIG. 1, it is formed so as to enter inside (downward in FIG. 1) from the upper edge 12 of the main body portion 10a. The first cuts 21a and 21b are formed so as to extend in a direction intersecting the planned folding line O (vertical direction in FIG. 1), that is, in a direction toward the planned folding line O. In the present embodiment, as shown in FIG. 1, since the planned folding line O and the upper edge 12 are parallel to each other, both the first cuts 21a and 21b are in the directions orthogonal to both the planned folding line O and the upper edge 12. It is formed to extend. The first cuts 21a and 21b are preferably parallel to each other, but may not be parallel as long as the ventilation holes 26 are formed so as to be sandwiched between them. In the present embodiment, the first notch 21 and the third notch 23 are all contained in the main body portion 10a and do not reach the main body portion 10b, but may be formed so as to reach the main body portion 10b.

The section surrounded by the first notch 21 and the third notch 23 becomes the peeling portion 24. In the present embodiment, the peeling portion 24 is formed by the four first cuts 21 and the third cut 23. Three ventilation holes 26 are formed side by side in the longitudinal direction (left-right direction in FIG. 1) along the first notch 21 of the peeling portion 24. Each of the three ventilation holes 26 is formed so that the center thereof is located between the first cuts 21a and 21b. As described above, the ventilation holes 26 penetrate the packaging mount 20 except for the protective layer 35, but are closed by the protective layer 35, which is the layer on the first surface 20a side. .. The distance between the first notches 21a and 21b is not particularly limited, but may be any time as long as the distance is such that the ventilation holes 26 are sandwiched between them.

As shown in FIG. 1, the first notches 21a and 21b parallel to each other are formed in the vertical direction over a range sandwiching all the ventilation holes 26. In the present embodiment, the first cuts 21a and 21b are formed so as to be parallel to each other with the same inclination, but the first cuts 21a and 21b are parallel as long as the ventilation hole 26 is sandwiched between them. They may be formed with different inclinations. When it is formed in the vertical direction over the range sandwiching all the ventilation holes 26, it is possible not to form the third notch 23. When the third notch 23 is not formed, the circumference of the peeling portion 24 in which the ventilation hole 26 is present is not completely surrounded by the notch. Therefore, the lower end portion of the peeling portion 24 on the planned folding line O side is not cut off neatly, but at least the range where all the ventilation holes 26 exist can be delaminated toward the planned folding line O. , All ventilation holes 26 can be ventilated.

Only one second notch 22 is formed on the second surface 20b of the packaging mount 20 so as to extend in the direction along the upper edge 12 of the main body portion 10a. In the present embodiment, as shown in FIG. 1, the main body portion 10a is formed on the same straight line as the upper edge 12. Further, the length of the second notch 22 is influenced by the first notch 21. Specifically, the second notch 22 is formed so as to connect the first notch 21a and the first notch 21b. When the first cuts 21a and 21b are parallel to each other and are formed so as to extend in a direction orthogonal to the upper edge 12 as in the present embodiment, the length of the second cut 22 is the first. It is equal to the distance between the cuts 21a and 21b. In the present embodiment, the second notch 22 is formed on the same straight line as the upper edge 12 of the main body portion 10a, but is formed so as to extend in the direction along the upper edge 12 of the main body portion 10a. For example, it does not have to be parallel to the upper edge 12, and may be formed above the upper edge 12 or below the upper edge 12.

The first cuts 21a and 21b and the second cut 22 are formed in a direction intersecting each other. Since the first notches 21a and 21b intersect with the second notch 22, the second notch 22 functions as a trigger for peeling the peeling portion 24. Assuming that the direction in which the first cuts 21a and 21b extend is the first direction and the direction in which the second cut 22 extends is the second direction, the angle between the first direction and the second direction is 60 ° or more and 120 ° or less. preferable. In the examples of FIGS. 1 and 2, the first direction is the vertical direction (Y direction) of the drawing, the second direction is the horizontal direction (X direction) of the drawing, and the first direction and the second direction are orthogonal to each other. The angle between the direction and the second direction is 90 °. The angle between the first direction and the second direction is most preferably 90 °. What is important is to link the first notch 21 and the second notch 22 so that the peeling portion 24 can be easily peeled off.

FIG. 5 is a cross-sectional view showing a detailed layer structure of the packaging mount according to the present embodiment. Similar to FIG. 3, it is a cross-sectional view seen from the direction corresponding to the line AA of FIG. In FIG. 3, a detailed layer structure is omitted in order to avoid complication of the drawing, but in reality, the packaging mount 20 has a printing layer and a heat-sealing layer. In FIG. 5, 31 is a paper substrate, 32a is a first side printing layer, 32b is a second side printing layer, 33 is a heat seal layer, 34 is a barrier layer, and 35 is a protective layer. As shown in FIG. 5, in reality, the first side printing layer 32a and the second side printing layer 32b for printing for advertising, explanation, etc. of the product, and the inner surface of the packaging mount 20 are the first. The heat seal layer 33 for adhering the two surfaces to each other is laminated on the paper base material 31.

As the paper base material 31, a multi-layered paper such as cardboard can be used. The thickness of the paper substrate 31 is preferably 200 μm or more and 600 μm or less. The basis weight of the paper substrate 31 is preferably 270 g / m ² or more and 400 g / m ² or less, and particularly preferably 300 g / m ² or more and 350 g / m ² or less. If these thicknesses and basis weights are less than the lower limit, the strength of the packaging mount 20 as a whole becomes weak when the first notch 21, the second notch 22, the third notch 23, and the ventilation hole 26 are formed. This is because when these thicknesses and basis weights exceed the upper limit, there is a high possibility that delamination will occur at a position deeper than the deepest part of the first cut 21, the second cut 22, and the third cut 23.

The first side printing layer 32a and the second side printing layer 32b can be formed by a known printing method such as gravure printing, offset printing, and inkjet printing. The heat-sealing layer 33 is for heat-bonding the second surfaces, which are the inner surfaces of the packaging mount 20, to each other, and is formed by applying a heat-sealing agent. As the heat sealant, a polyester-based, acrylic-based, vinyl acetate-based resin, or a mixture of these resins can be used.

The barrier layer 34 has water vapor and other gas barrier properties, and an appropriate one is selected according to the required function. When gas barrier properties are required, a vapor deposition layer of a metal such as aluminum, a metal oxide such as aluminum oxide, or an inorganic oxide such as silicon oxide is provided. The thin-film deposition layer may be laminated on the paper substrate 31. Alternatively, it may be a metal leaf such as aluminum. In addition, a resin layer having a gas barrier property such as an ethylene-vinyl alcohol copolymer (EVOH), a polyvinylidene chloride resin (PVDC), or an aromatic polyamide such as nylon MXD6 may be used.

The protective layer 35 is for closing the ventilation hole 26, and it is necessary to maintain a certain degree of airtightness until the peeling portion 24 is peeled off. It is a thing. Therefore, as the protective layer 35, a material applicable to the barrier layer 34 as described above can be used, but a polyester film such as polyethylene terephthalate or polybutylene terephthalate, a polyamide film such as nylon, or a polypropylene film may be used. Can be done. The thickness is about 10 μm to 50 μm. The protective layer 35 is preferably biaxially stretched. Further, in the present embodiment, the protective layer 35 has transparency so that a person can recognize the existence of the ventilation holes 26. As the purpose of the "transparency" here, it is sufficient that the transparency is such that a person can recognize the existence of the ventilation hole 26. For example, it is preferable that the total light transmittance specified in JIS K7361 is 80% or more. However, since it is not always necessary for a person to recognize the existence of the ventilation holes 26, in that case, the protective layer 35 may not have transparency.

<Manufacturing method>
A method for manufacturing a packaging container according to this embodiment will be described. First, the manufacturing of the wrapping mount will be described. First, the barrier layer 34 is formed on one surface of a paper base material 31 such as cardboard. The barrier layer 34 can be formed by laminating aluminum foil, for example, by a dry laminating method using an adhesive or the like. Next, advertisements, product descriptions, and the like are printed on each of the paper base material 31 and the barrier layer 34 by gravure printing, offset printing, or the like. As a result, the first side printing layer 32a is formed on the first side 20a side of the paper base material 31, and the second side printing layer 32b is formed on the second side 20b side of the barrier layer 34. Subsequently, the heat sealant is layered on the second side printing layer 32b and applied over the entire surface by a known coating method such as a roll coater to form the heat seal layer 33.

Further, a through hole serving as a ventilation hole 26 is formed. In the present embodiment, a total of three ventilation holes 26 are formed at predetermined positions between the first cuts 21a and 21b. Next, the protective layer 35 is formed by superimposing it on the first side printing layer 32a. The protective layer 35 can be laminated by using a dry laminating method, a melt extrusion method, or the like. As a result, the ventilation hole 26 is closed on the first surface 20a side, which is the outer surface. Subsequently, a half-cut process is performed from the second surface side, which is the inner surface, to form the second notch 22.

Next, the planned folding line O, the first cut 21, and the third cut 23 are continuously formed and punched. The planned fold line O is formed as a fold groove by processing from the second surface side, which is the inner surface, by a push rule, and the first cut 21 and the third cut 23 are half-cut from the first surface 20a side, which is the outer surface. It is formed by processing. The punching process is performed using a Thomson blade. The depths of the first notch 21, the second notch 22, and the third notch 23 are all 1/5 or more and 1/2 or less of the thickness of the wrapping mount 20, and penetrate the wrapping mount 20. Not deep.

As a result of die cutting, a wrapping mount as shown in FIGS. 1 to 5 is formed. The depths of the first notch 21, the second notch 22, and the third notch 23 are 1/5 or more and 1/2 or less of the thickness of the paper substrate 31, and the heat seal layer 33 to the protective layer 35 are covered. It is preferably 1/5 or more and 1/2 or less of the total thickness of the packaging mount 20 including the wrapping paper. In particular, the depths of the first notch 21, the second notch 22, and the third notch 23 are 1/3 or more and 1/2 or less of the thickness of the paper substrate 31, and the heat seal layer 33 to the protective layer 35. It is more preferable that the thickness of the entire packaging mount 20 including the above is 1/3 or more and 1/2 or less.

The contents are placed on the second surface 20b side, which is the inner surface, folded along the planned folding line O, and the outer edges of the facing second surfaces 20b are heat-sealed (heat-sealed). Since the heat seal layer 33 is formed on the second surface 20b side of the packaging mount 20, heat bonding is possible. As described above, the packaging container containing the contents is completed. That is, a product in which the contents are contained in a packaging container formed from the packaging mount 20 shown in FIGS. 1 to 5 can be obtained. FIG. 6 is a diagram showing a packaging container thus obtained. FIG. 6A is a front view seen from the main body portion 10a side, and FIG. 6B is a rear view seen from the main body portion 10b side. When the fragrance is contained as the content, the fragrance product is sold to the consumer in the state shown in FIG. The packaging container shown in FIG. 6 has a form imitating a hanger.

<State at the time of opening>
From the state shown in FIG. 6, the user first picks the grip portion 25 of the peeling portion 24 and then picks the grip portion 25 of the main body portion 10a (the front side in FIG. 6 (a) and the back side in FIG. 6 (b)). Apply force to. The knob portion 25 is separated from the peeling portion 24 by the second notch 22 on the second surface 20b side of the main body portion 10a, and is connected to the peeling portion 24 on the first surface 20a side of the main body portion 10a. Further, the knob portion 25 is separated from the main body portion 10a by the second notch 22 on the second surface 20b side of the main body portion 10a. Therefore, when the picking portion 25 is picked and a force is applied to the main body portion 10a side (the front side in FIG. 6A and the back side in FIG. 6B), as shown in FIGS. 7A and 7B. The knob portion 25 bends toward the main body portion 10a while being connected only to the peeling portion 24. 7A is a front view corresponding to FIG. 6A, and FIG. 7B is a cross-sectional view corresponding to CC of FIG. 7A.

From the state shown in FIG. 7, the knob portion 25 bent toward the main body portion 10a is pulled in the direction along the first cuts 21a and 21b. Then, in the peeling portion 24, a force is applied to the first surface 20a side of the main body portion 10a in which the first cuts 21a and 21b of the half cut are formed, and the first cuts 21a and 21b are not formed and the peeling portion 24 is formed. Delamination occurs between the surface and the second surface 20b side where the other portion is continuous. Such delamination is likely to occur because the paper substrate 31 is a multi-layer paper. FIG. 8 shows a state in which the peeling portion 24 is delaminated to a position exceeding the ventilation hole 26. FIG. 8 is a view of the packaging container as viewed from the front side. Since the protective layer 35 covering the ventilation hole 26 is located on the first surface 20a side, it is peeled off together with the peeling portion 24.

Therefore, air can flow in and out through the ventilation holes 26. For example, if an fragrance is contained as the content, the scent will drift. The peeling portion 24 can be pulled as it is toward the planned folding line O which is the lower edge of the packaging container, delaminated to the end point (lower end) shared by the third cuts 23a and 23b, and separated from the main body. As described above, the third notch 23 does not necessarily have to be continuously formed in the first notch 21, but in order to cleanly separate the peeled portion 24, the third notch 23 is formed. It is preferable to surround the peeling portion 24 with a notch. In this way, by suspending the entire packaging container using the hanging portion 11 with the three ventilation holes 26 penetrating, the scent of the fragrance drifts from the three ventilation holes 26. .. After peeling off the peeling portion 24 to release the scent, the outer garment is hung on the main body 10 of the packaging container and hung using the hanging portion 11 so that the outer garment can be used during storage. It is possible to attach a good scent.

<Example>
As the paper base material 31 and the barrier layer 34, an aluminum laminated paper "Milux (thickness 0.36 mm, basis weight 310 g / m ² )" manufactured by Tribe Co., Ltd. was used. After printing on both sides of this aluminum laminated paper by offset printing, the heat sealant "BP-50 Kai" manufactured by Nippon Kako Paint Co., Ltd. is applied on the printing layer on the aluminum side, and the coating fee is 5 g / m. It was applied so that it became ² . Subsequently, three circular through holes having a diameter of 6 mm, which are used as ventilation holes 26 by a punching die, were formed at equal intervals so that the centers thereof were linearly arranged. The distance between the centers of the ventilation holes 26 was set to 30 mm. Then, a polyethylene terephthalate (PET) film having a thickness of 12 μm was bonded by a dry laminating method using an adhesive.

Subsequently, a half-cut process was performed from the heat-seal layer side using a cutting blade mold to form a second notch 22 having a length of 20 mm at a position serving as the upper edge of the main body. Next, a folding groove having a length of 276 mm is formed as a scheduled folding line O by processing at a predetermined position by pressing a ruled line, and then half-cut processing is performed from the PET film side using a cutting blade to perform a half-cut processing on the main body. The upper edge of the portion and the non-penetrating first cuts 21a and 21b extending in the direction orthogonal to the scheduled folding line O are both formed with a length of 90 mm, and share one end point with the first cuts 21a and 21b, respectively, and the other. The third notches 23a and 23b, which share the end points of the above, are both formed to have a length of 15 mm. The angle formed by the first notch 21a and 21b with the second notch 22 was 90 °. That is, the first cuts 21a and 21b are orthogonal to the second cut 22 in the plane direction of the paper base material 31. Finally, punching was performed according to the outer shape using a Thomson blade, and a wrapping mount as shown in FIGS. 1 to 5 was obtained. The size of the outer shape of the wrapping mount is 300 mm in the direction along the scheduled folding line (left-right direction (X direction) in FIGS. 1 and 2) and in the direction orthogonal to the scheduled folding line (vertical direction (Y) in FIGS. 1 and 2). Direction)) was 340 mm.

After that, an fragrance is placed as a content on the second surface 20b, which is the inner surface, folded at the planned folding line O, and the opposite second surfaces 20b are heat-sealed (heat-sealed) to contain the fragrance. I made a container. In this packaging container, when the knob portion 25 was picked and bent toward the main body portion 10a and pulled toward the planned folding line O which is the lower edge of the packaging container, the peeling portion 24 continuous with the knob portion 25 was delaminated. The ventilation holes 26 are exposed. Then, the scent from the fragrance in the housing was released, and it was confirmed that the scent was scented.

Although the preferred embodiment of the present invention has been described above, the present invention is not limited to the above embodiment and can be modified in various ways. For example, in the above embodiment, three ventilation holes 26 are formed, but only one or two may be formed, or four or more may be formed.

Further, in the above embodiment, a heat seal layer is formed on the second surface in order to bond the second surfaces to each other. However, if it is possible to bond the second surfaces to each other, a method using a sealant film or the like may be used. The adhesive layer may be formed by another method.
