Problems solved by technology

[0012] Therefore, for example, when the consumer peels off the lid of the package and unseals, sometimes the cutting burr on the end face of the flange of the container hits the finger and feels awkward or unpleasant, and when the end face is grasped firmly, it may feel uncomfortable. finger pain
[0013] In addition, there is only one kind of container that curls the flange portion of the container so that the end surface is not exposed, but in order to curl the flange portion, the shape of the molding die will become complicated, and the number of steps will increase, so there are Problems such as rising costs

Embodiment Construction

[0044] Below, refer to Figure 1~4 Embodiments of this invention will be described.

[0045] figure 1 The overall configuration of the package of the present invention is shown.

[0046] The illustrated package 1 is configured by filling and packaging contents C such as food with a container 2 and a cover 3 .

[0047] The container 2 is formed by molding a composite sheet 20 into a cup shape, and has a horizontal flat flange portion 21 on its upper opening periphery.

[0048] The lid 3 is composed of a composite sheet 30 cut into a predetermined size and shape, and its peripheral edge is thermally welded to the upper surface of the flange portion 21 of the container 2 so as to cover the upper opening of the container 2 filled with the contents C. .

[0049] In addition, a handle portion 31 is formed on the cover 3, and the handle portion 31 protrudes radially outward from a part of the peripheral portion of the cover 3 and is gripped with fingers when the cover 3 is peeled...

Abstract

The present invention provides a container and a package using the container at a low price. The container is formed by molding a composite sheet having a metal foil layer excellent in barrier properties, and it does not suffer from the The resulting cutting burrs make consumers' fingers feel awkward, unpleasant or painful. The container (2) is formed by forming a composite sheet (20) with resin film layers (202), (203) laminated on both sides of a metal foil layer (201) into a cup shape, and a flange portion (21) is provided at the periphery of the opening. , the cutting burr (201a) generated on the end surface of the flange portion (21) faces the opening side of the container (2).

Description

technical field [0001] This invention relates to a container formed by molding a composite sheet having a metal foil layer and a resin film layer into a cup shape, and a package using the same. [0002] In this specification and claims, "cutting burr" refers to the protrusion of the metal foil that occurs on the cross section, that is, the end surface of the flange portion of the container, due to the cutting of the above-mentioned composite sheet before or after molding. . Background technique [0003] As a container for packaging contents requiring long-term storage, there is known a container formed by molding a composite sheet into a cup shape, wherein the composite sheet has a metal such as aluminum foil that is excellent in barrier properties to gas, moisture, light, etc. A foil layer and a resin film layer laminated on one or both sides of the metal foil layer. [0004] The above-mentioned container is formed by thermally welding a lid formed of a composite sheet ha...
