Description

[Detailed description of the invention] The present invention relates to a paper container product filled with beverage liquids such as juice, coffee, etc., and its purpose is to make it similar to metal cans even though it is made of paper. It has pressure resistance and can be used in vending machines, etc.

Conventionally, containers for drinks, coffee, and similar beverages used in vending machines have been metal cans, but the present invention replaces these containers with inexpensive paperboard.
It is designed to achieve its purpose by layering it in layers.

In other words, the container of the present invention has a temperature of 80 to 95°C inside the tapered paper container.
The bottom plate is filled with a similar beverage liquid such as juice, coffee, etc. heated to
An outer paper container, which has a square or octagonal shape and has a cylindrical body on its outer surface, is fitted onto the inner paper container, and the mouth edge of the outer paper container is connected to the crowned part of the inner paper container. It is welded to the inner paper container at a position close to the edge of the lid, making it double layered inside and outside to provide pressure resistance.The outer paper container is generally straight, so it rolls easily and is automatic. It can withstand the use of vending machines and the like.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The paper container filled with a beverage liquid of the present invention includes an inner paper container A having a taper shape as a whole;
It consists of a lid B that covers the opening of the container, and an outer paper container C having a cylindrical body that fits over the inner paper container A.

The inner paper container A has a tapered body a made of paper 1 whose inner and outer surfaces are coated with a synthetic resin 2 such as polyethylene or polypropylene, and a bottom plate b which is made of paper 1 coated with a synthetic resin 2 such as polyethylene or polypropylene. Because of this, it has an upper base.

This bottom plate b is also made of the same material as the body a, and is welded to the body a.

A similar beverage liquid l such as juice or coffee is heated to 80 to 95°C and filled into the inner paper container A. The lid B, which is made of a material in which the surface of an aluminum plate 3 is coated with a resin 4 such as polyethylene or polypropylene, clamps the opening 6 of the inner paper container A at the bent portion 5 of its peripheral edge and heat-seals it. At this time, the bottom surface of lid B is
It is attached to the filled drinking liquid l surface.

Here, in order to prevent the quality of the filled drinking liquid l, if it is rapidly cooled with water etc., the drinking liquid l
The container is deformed due to the external pressure as it contracts, but since the aluminum plate lid B is relatively strong, the body a of the container deforms.

In the present invention, in order to hide the deformation of the body a of the inner paper container A having such a taper and to use it in a vending machine like a conventional metal can, this inner paper container An outer paper container C having a cylindrical body is fitted onto A to make it double and integrated.

That is, in this outer paper container C, the bottom plate c connected to the body d has a hexagonal or octagonal shape, and is folded into a flat shape together with the body d. By pressing in a direction perpendicular to the direction in which the opening 7 is formed, the opening 7 becomes circular and a hexagonal or octagonal bottom plate c is assembled to form the outer paper container C.

Here, an inner paper container A having a conical taper and filled with a beverage liquid 1 is fitted into this outer paper container C. At this time, the inside of the opening 7 of the outer paper container C and the outside of the body a close to the edge of the lid B of the inner paper container A are in a state of tight fitting. C and inner paper container A are welded together. At this time, the lower end of the body a comes into contact with the assembled bottom plate c.

In this way, when the inner paper container A filled with the beverage liquid 1 and the outer paper container C are integrated, both ends of the container are covered with a lid B having the aluminum plate 3 as a substrate and an assembled bottom plate c. Therefore, even if the bottom plate c has a hexagonal or octagonal square shape, the outer surface is generally straight and cylindrical, making it possible to create a product that can be used in vending machines, etc. climb.

Next, the formation of the outer paper container C when the bottom plate c has a hexagonal shape will be specifically explained.

Figure 4 shows a blank plate D punched out from paper 1 coated with a synthetic resin such as polyethylene or polypropylene 2 before assembling the outer paper container C.
This is a view from the inside, which consists of a straight cylindrical body d and a folded bottom plate c made of a plurality of pieces.

The fuselage d has fold lines 9 ₁ to 9 ₅ formed on the side of the bottom plate c to divide it into six equal sections 8 ₁ to 8 ₆ , of which lines 9 ₂ and 9 ₅ reach the folded edge 10 of the mouth. An adhesive piece 11 is provided outside the fold line 9 ₆ of the section 8 ₆ . The bottom plate c consists of a plurality of pieces, and a regular hexagonal bottom plate main body 12 projects from the section ₈₄ of the body d, and a fold line 13 is formed in the center of the bottom plate main body 12. Category 8 ₂ and 8 ₃ and 8 ₅
and ₈₆ , semicircular protrusions 14 and 14' are provided, and these protrusions 14 and 14' are
Fold lines 15 and 15' and notches 16 and 16' are provided in the protruding direction at 60 degrees angles from the bases of the fold lines 9 ₂ and 9 ₅ . These fold lines 15 and 15', cutting depth 1
The projecting pieces 14 and 14' by 6 and 16' are connected to the three sector pieces 17, 17', 17'' and 18, 1, respectively.
It is divided into 8' and 18''. An inverted shoe-shaped piece 19 is protruded from the section ₈₁ .

In order to form such a blank plate D as a foldable container, first, as shown in FIG.
9. The semicircular protruding piece 14, the bottom plate main body 12, and the semicircular protruding piece 14' are each folded into the body d along the folding line 20 ₁ to each section.
20 Fold inward from ₆ , then fan-shaped piece 17,1
Fold the folding lines 15 and 15' of 7', 18, 18', and the folding line 13 of the bottom plate main body 12 so that they respectively protrude to the outside.

In such a folded state, the inverted shoe-shaped piece 19,
Adhesive is applied to the outer surfaces of each of the fan-shaped pieces 17'', 18'' and the adhesive piece 11, and the mouth edge 10 is
Fold and glue from the fold lines 9 ₂ and 9 ₅ that reach up to .

To assemble the folded container thus formed as an outer paper container C, press the fold lines 9 ₂ and 9 ₅ extending up to one edge 10 of the opening from the outside to the inside, and the body d opens. The bottom plate body 12 has a circular shape on the part 7 side and a hexagonal shape on the side of the bottom plate c part, and the bottom plate main body 12 is adhered to the outer surface of the inverted boot-shaped piece 19, and the outer surfaces of the fan-shaped pieces 17'' and 18'' are shaped like a fan-shaped piece. When placed on the fan-shaped pieces 17 and 17'' and 18 and 18'' that are adhered to the inner surfaces of 17' and 18', the outer paper container C is completed.

The paper container product filled with beverage liquid of the present invention is
As explained above, an inner paper container with a taper shape filled with a beverage liquid and covered with an aluminum plate is fitted into an outer paper container with a cylindrical body whose bottom plate is reinforced by assembly. However, since the mouth edge of the outer paper container and the edge of the lid of the inner paper container are welded together near the edge of the lid, the body of the inner paper container may be deformed during the filling process. The container is concealed by the outer paper container and has a good appearance, and both ends are reinforced with aluminum plate lids and the assembled bottom plate, making the container as a whole double-layered and pressure-resistant. Although it has a rectangular shape, the outer surface is generally straight, so it can be used in vending machines, and even though it is a paper container, it can be used in the same way as a metal can. Moreover, since the material is entirely paper, it can maintain its temperature for a long time when taken out from the vending machine.

It is also inexpensive and can be disposed of by incineration after use.
