Abstract

(57) [Abstract] [Purpose] The present invention provides a paper container that is made of cardboard that does not cause pollution and that can be stacked in large numbers. [Structure] The present invention is composed of a substantially rectangular cardboard whose surface is covered with a synthetic resin film through a coating part.
It is intended to provide a paper container characterized by including a main body in which corners are cut and joined and each peripheral surface portion is inclined in a direction of expanding upward.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a paper container mainly made of cardboard, and is particularly suitable for containing foods and the like.

[0002]

[Prior art]

 Conventionally, foods and the like have been stored in a container made of foamed resin for sale, but this type of container has a problem that pollution occurs when treating a discarded product after use. In addition, the conventional paper containers are box-shaped, and even if they are slightly stacked, the height increases.

[0003]

[Problems to be solved by the device]

 This invention provides a paper container that is made of cardboard that does not cause pollution and that can be stacked in large numbers.

[0004]

[Means for Solving the Problems]

 This invention includes a main body which is made of a substantially rectangular cardboard whose surface is covered with a synthetic resin film and has four corners cut and joined to each other so that each peripheral surface portion is inclined upward. The present invention provides a paper container characterized by the above.

[0005]

[Action]

 Since the paper container according to the present invention is paper, it does not cause pollution such as foamed resin when treating discarded items, and since the peripheral surface is inclined outward, it is possible to stack many. It is made and easy to process.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In one embodiment of the present invention shown in FIGS. 1 to 3, reference numeral 10 denotes a main body of a container, and the paper container according to the present invention may be provided with a lid, but may be only a main body without a lid. . Although not shown, the main body 10 has commercially available inner coated synthetic resin films stacked and adhered on the inner and outer surfaces of the cardboard. Painted synthetic resin films have been on the market for a long time, but their adhesiveness to Styrofoam was poor and they were not often used. In this invention, when the coated synthetic resin film was bonded to the cardboard with a hot melt adhesive, it became possible to bond very well, and this could be used practically. Further, the cardboard itself may be coated so as to be covered with a transparent synthetic resin film which is not coated, as long as a coated portion is formed between the cardboard and the synthetic resin film.

As shown in a partially developed view of FIG. 3, the main body 10 has cut portions 12 formed at four corners and is bent at bent portions 14, 15, 16, 17 and the like indicated by dotted lines to form two pieces at four corners. The joint pieces 20 formed separately are joined to each other, and each peripheral surface portion 23 is inclined so as to expand upward. The peripheral surface portion 23 can have various inclination angles as long as the peripheral surface portion 23 is inclined so as to expand upward. For example, as shown in the embodiment shown in FIG. As shown, the peripheral surface portion 23 is inclined at a steeper angle, or as in the embodiment shown in FIG. 5, it is cut as shown in (a) and bonded so that the joint pieces 20 partially overlap each other. (B), the peripheral surface portion 23 may be inclined at a gentler angle.

In this invention, partition members 25 and 26 may be provided on the main body 10 as shown in FIGS. For example, the lower central part of the partition member 25 is adhered to the inner surface of the main body 10 with an adhesive, and the ends of the two partition members 26 are adhered to the partition member 25. FIG. 8 shows a lid 30 provided on the main body 10 if necessary, and this lid is also made of the same material as the main body 10.

[0009]

[Effect of device]

 As described above, this invention is suitable for accommodating foods because the peripheral surface portion 23 is inclined in the direction of expanding upward, so that a large number of stacks can be stacked, processing is easy, and water resistance is provided. Since it is made of paper, it has the effect of not causing pollution even if it is discarded.
