Description

TECHNICAL FIELD The present invention relates to a container for storing a sticky substance, and particularly to a container that can be easily peeled off when taking out the contained sticky substance.

For example, Patent Document 1 discloses a container for adhesive substances. The inside of the container is divided into a plurality of booths, and each booth accommodates a folding paper carton made of one paper sheet. A release layer made of silicone is formed on one side of the paper sheet. The paper sheet is folded so that the release layer is on the inner surface of the folding paper carton, forming a box-shaped folding paper carton with an open top surface.

Japanese Patent Application Publication No. 2011-157107

In Patent Document 1 mentioned above, in addition to the container itself, a folding paper container is required to accommodate the sticky material. Foldable paper cartons must be made by folding paper sheets. Therefore, the cost was high.
In view of these circumstances, it is an object of the present invention to provide a container for sticky materials that can be easily separated even if the sticky materials are directly stored therein, and that can be manufactured at low cost.

In order to solve the above problems, the present invention provides a container for storing a sticky substance, comprising:
A container body made of paper cardboard,
glassine paper attached to the inner surface of the container body via an adhesive layer;
a release layer laminated on the inner surface of the glassine paper;
It is characterized by having the following.

Preferably, the release layer is laminated on the inner surface of the glassine paper with a base layer interposed therebetween.

Preferably, a film layer made of a thermoplastic resin is interposed between the glassine paper and the release layer.
Preferably, the release layer is laminated on the inner surface of the film layer with a base layer interposed therebetween.
Preferably, the thermoplastic resin includes polyethylene terephthalate (PET).

According to the container for sticky substances according to the present invention, even if sticky substances are directly stored, they can be easily separated, and the cost can be reduced.

FIG. 1(a) is a perspective view of a container for adhesive materials according to a first embodiment of the present invention. FIG. 1(b) is an exploded perspective view of the sheet serving as the adhesive container. FIG. 2 is an enlarged sectional view showing the cross-sectional structure of the adhesive container according to the first embodiment of the present invention. FIG. 3 is a cross-sectional view showing the cross-sectional structure of a container for adhesive substances according to a second embodiment of the present invention.

Embodiments of the present invention will be described below with reference to the drawings.
<First embodiment (FIGS. 1 and 2)>
FIG. 1(a) shows an example of the adhesive container of the present invention. The adhesive container 1 is formed in the shape of a rectangular parallelepiped box with an open top surface. Preferably, the adhesive container 1 is formed by folding a single sheet 2 shown in FIG. 1(b). The top open portion of the adhesive container 1 may be closed by a lid box or an outer box (not shown).

As shown in FIG. 1(a), a sticky material a is accommodated inside the container 1 for sticky material. Examples of the sticky substance a include sticky food raw materials such as gum base and chemical products such as hot melt adhesives.

As shown in FIG. 2, the seat 2 includes a seat body 3 and an inner laminate 20. As shown in FIG. The sheet body 3 constitutes a container body 10 in the container 1 for adhesive substances. The sheet body 3 and, in turn, the container body 10 are made of paper cardboard 4. The paper corrugated board 4 includes a pair of outer liner 11 and inner liner 12, and a corrugated sheet 13 sandwiched between these liners 11 and 12. These liners 11, 12 and corrugated sheet 13 are made of paper. The contact portions of each liner 11, 12 and the corrugated sheet 3 are adhered with an adhesive (not shown). The outer liner 11 constitutes the outer surface (lower surface in FIG. 2) of the container body 10. The inner surface liner 12 constitutes the inner surface (the upper surface in FIG. 2) of the container body 10.

An inner surface laminate 20 is laminated on the inner surface liner 12. The inner laminate 20 includes glassine paper 21 and a release layer 22.
A glassine paper 21 is attached to the inner surface of the inner liner 12 and, ultimately, to the inner surface of the container body 10 (the surface facing into the container 1) via an adhesive layer 23. The glassine paper 21 has a function as a base material for holding the mold release layer 22 and a function as a bonding material for bonding the mold release layer 22 to the container body 10. Preferably, the glassine paper 21 is applied over the entire area of the inner liner 12. Preferably, the adhesive layer 23 is applied over the entire surface of the inner liner 12.

A release layer 22 is laminated on the inner surface of the glassine paper 21 (the surface facing into the container 1, the upper surface in FIG. 2). The release layer 22 is made of a material that has low adhesion to the adhesive material a. Examples of the material for the release layer 22 include silicone and fluorine-containing substances. Preferably, the release layer 22 is laminated over the entire area of the glassine paper 21.

More preferably, a base agent layer 24 is interposed between the glassine paper 21 and the release layer 22. The base agent layer 24 is made of, for example, a primer, and improves the adhesion between the glassine paper 21 and the release layer 22. Components of the primer include urethane-based, acrylic-based, ester-based, and other resins. Preferably, the base layer 24 is applied over the entire inner surface (upper surface in FIG. 2) of the glassine paper 21.

In the adhesive container 1, the release layer 22 constitutes the inner surface of the container. The adhesive material a accommodated in the adhesive material container 1 comes into contact with the release layer 22 . Therefore, it is possible to avoid the sticky substance a from sticking to the container body 10 made of paper cardboard 4.
Since the release layer 22 has low adhesion to the adhesive material a, the adhesive material a can be easily peeled off from the adhesive container 1 when the adhesive material a is used. Therefore, according to the container 1 for sticky substances, even if the sticky substance a is directly accommodated, it can be easily separated.
The adhesive container 1 does not require a separate member such as a folding paper container (see Patent Document 1), so the cost can be reduced.

Next, other embodiments of the present invention will be described. In the following embodiments, the same reference numerals are attached to the drawings for structures that overlap with those already described, and the description thereof will be omitted.
<Second embodiment (Fig. 3)>
As shown in FIG. 3, in the sheet 2B and, by extension, the adhesive container 1B according to the second embodiment of the present invention, the inner laminate 20B includes a film layer 30. A film layer 30 is interposed between the glassine paper 21 and the release layer 22. The film layer 30 is composed of a film made of thermoplastic resin. The thermoplastic resin constituting the film layer 20 is preferably polyethylene terephthalate (PET).

A second adhesive layer 32 is interposed between the glassine paper 21 and the film layer 30. Glassine paper 21 and film layer 30 are bonded together via second adhesive layer 32 . Preferably, the second adhesive layer 32 is applied over the entire opposing surfaces of the glassine paper 21 and the film layer 30.
The film layer 30 allows the adhesive container 1B to have stiffness.

The release layer 22 is laminated on the inner surface of the film layer 30 (the surface facing into the container 1B, the upper surface in FIG. 3) via the base agent layer 24B. Preferably, the base layer 24B is applied over the entire inner surface of the film layer 30. The base layer 24B is made of, for example, the same primer as the base layer 24 of the first embodiment, and improves the adhesion between the film layer 30 and the release layer 22.

The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit thereof.
For example, if the release layer 22 is directly adhered to the glassine paper 21 or the film layer 30, the base agent layers 24 and 24B may be omitted.
The film layer 30 may be melt-laminated and directly laminated on the inner surface of the glassine paper 21, and the second adhesive layer 32 may be omitted.

The present invention can be applied, for example, to containers containing adhesive substances such as gum base.
