DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A storage container according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a storage container according to an embodiment of the present invention. Reference numeral 1 is a bottle body as a container body, and a cylindrical paper sleeve 2 is provided on a peripheral wall portion of the bottle body 1. It is installed. The bottle body 1 is, for example, a bottle obtained by blow molding a polyethylene terephthalate (PET) preform, and in particular, the body portion 1a is formed thin and the mouth portion 1b is formed slightly thick. This bottle body 1
Is formed in the shape of a PET bottle filled with a soft drink such as cola or juice in this embodiment, it is a box-shaped pack-shaped container for liquor, soy sauce, mirin, oil, detergent, paste, oil, etc. It is also possible to apply it in a bottle.

The sleeve 2 fitted around the body 1a of the bottle body 1 is made of, for example, paperboard having a wall thickness of 0.2 mm to 1 mm, and is fitted to the cross-sectional shape of the body 1a of the bottle body 1. It has a cross-sectional shape. Although the sleeve 2 is formed in a cylindrical shape without a bottom in this embodiment, it is of course that the sleeve 2 may be formed with a bottom, and the sectional shape of the sleeve is not limited to a cylindrical shape but may be a rectangular shape. It may have a cross-sectional shape. Further, the upper part of the sleeve 2 may be formed in a funnel shape so as to cover the periphery of the mouth 1b of the bottle body 1 so that the mouth 1b projects from the upper end of the sleeve 2.

Foaming ink is printed on the surface of the sleeve 2 as shown in FIG. 2, and the foaming portion 3 is formed by the foaming ink as a slip stopper. This foam ink is applied linearly in the longitudinal direction of the sleeve 2,
Although it does not slip in the longitudinal direction regardless of where the sleeve 2 is held, it may be applied in a ring shape around the sleeve 2. Alternatively, it may be formed in a dot shape, or may be solidly coated on the entire sleeve 2.
Of course, a plurality of types of foaming ink may be applied separately for color classification, or the foaming ink 3 may be made transparent so that the inside can be seen to form the foaming portion 3.

The foaming ink forming the foaming portion 3 is an ink that foams when heat is applied, and is conventionally used for various packaging materials, wallpaper, and decorative boards. Shall use those that comply with the Food Sanitation Law, food additives and other standards. Foaming ink is classified into a type using a capsule in which a volatile liquid is encapsulated in microspheres of a thermoplastic resin, and a plastic sol type in which microparticles of a plastic foam such as polystyrene are suspended. As a product,
For example, there are foam inks manufactured by Toka Dye Co., Ltd. or Dainichiseika Kogyo Co., Ltd.

In this embodiment, a plastic sol type foaming ink is used, and as the particles of the plastic foam, a sol in which polystyrene particles are dispersed is used. The polystyrene particles used are those that foam at 120 ° C.

The printing method of the foam ink is gravure printing,
It can be printed by screen printing, dipping, transfer, etc.
In this example, silk screen printing was used, and the screen mesh was 70 mesh and 100 mesh. In the case of 70 mesh, the ink application amount is approximately 60 to 70 μm, and in the case of 100 mesh, the ink application amount is approximately 20 μm to 40 μm.

As a foaming method, a plastic sol type foaming ink or a microsphere type ink is also preheated to be foamed by heating. The heating temperature and heating time are determined by the type of plastic foam particles, the heating method and the coating method. Since it depends on the quantity, select the conditions suitable for printing. In this embodiment, polystyrene particles that expand at 120 ° c are selected, so the heating temperature is 120 ° c.

The thickness of the foamed ink due to foaming increases as the thickness of the ink increases. For example, in the case of fine mesh 100 mesh, the film thickness of the foamed ink before foaming is as thin as 20 μm to 40 μm, so the film thickness of the foamed ink after foaming is 40 μm to 90 μm, and the foaming rate is almost double. It was However, in the case of 70 mesh, which is coarser than this, the film thickness of the foamed ink before foaming was 60 to 70 μm, but the film thickness of the foamed ink after foaming was 600 to 1000 μm.
m, and the foaming ratio was almost 10 times. Therefore,
The swelling state of the foamed ink applied to the sleeve 2 and the contact feeling or texture of the sleeve 2 can be adjusted not only by selecting the material of the foaming ink but also by selecting the mesh.

As a result of foaming such foam ink to form the foam portion 3, the surface of the foam portion 3 becomes a rough surface and protrudes from the surface of the sleeve 2, so that the sleeve 2 is prevented from slipping. Therefore, even if the amount of liquid in the bottle body 1 is reduced and the sleeve 2 is easily deformed, it is possible to prevent the sleeve 2 from slipping off between the grasping fingers. Also,
Since the foamed portion 3 has a shape that bulges on the surface of the sleeve 2 due to polystyrene foam, it can be used as a cushioning material, and also as a heat insulating material or a cold insulating material due to the heat insulating effect. In order to enhance the heat insulation effect, it is preferable to expand the printing area by solid-painting the foam ink. Further, since the foamed ink swells, the effect of memorizing the visual impression is enhanced by the three-dimensional design, and the effect of soundproofing, waterproofing, or blocking of ultraviolet rays is also provided. The foamed ink may be applied and foamed on the back side of the sleeve 2 to strengthen the fitting state between the sleeve 2 and the bottle body 1.

The symbol C is a cap. Further, in this embodiment, foam ink is applied as a slip stopper,
A suede ink having a rough surface to be applied may be applied instead of the foamed ink, or the foamed ink and the suede ink may be appropriately formed.
