Embodiment Construction

[0016] Next, embodiments of the paper container according to the present invention will be described with reference to the drawings.

[0017] In the embodiment, a tubular paper container will be described as an example of the paper container.

[0018] Such as figure 1 As shown in (a), the paper container 1 of the present embodiment is a paper container in which a laminated sheet using paper as a base material is trimmed into a circular shape to produce a cylindrical main body portion 30, and the cylindrical body portion The upper and lower parts of the main body part 30 are bent, and welded parts 3310 and 3320 provided around the top plate 331 and the bottom plate 332 are sandwiched and welded. Therefore, the top plate welded portion 3310 and the bottom plate welded portion 3320 of the paper container 1 are provided on the upper and lower sides with a constant width.

[0019] In addition, the opening 2 is formed in the top plate 331 . The handle 4 is welded to the top plate...

Abstract

In a tab fused to the periphery of an opening provided in a paper container to cover the opening, a pinching section of the tab can be easily held from the surface of the paper container in which theopening is provided. Furthermore, the present invention provides a paper container that can be opened by enabling the tab to be easily peeled off. A paper container according to the present inventionthat is formed of a paper-based laminated sheet and has a top (331) is characterized by having an opening (2) in the top of the container and having a tab (4) that can close the opening. By providing,in the tab, a closing section (42) that covers the opening, a protruding section (41) protruding out from the closing section, and a crease (43) between the closing section and the protruding section, a gap (44) is provided between an end of the protruding section of the tab and the top.

Description

technical field [0001] The present invention relates to a paper container and a method of making the same. The paper container is a paper container for accommodating beverages such as juice drinks, coffee, liquid soup, red bean soup, seasonings, rock salt, granular detergents, etc. The laminated sheets are formed by stamping or welding. Background technique [0002] Currently, paper containers using sheets for storing liquids such as coffee beverages, black tea beverages, cocoa beverages, Japanese sake, liquid soup, powdered soup, and amazake, powders and granules such as seasonings, rock salt, and granular detergents, etc. Paper containers for storage can be filled into large-capacity containers at high speed, and a filling machine that can easily handle various contents has been developed. [0003] In such a paper container compatible with a filling machine having a high fillability, an easy-peel tab (tab) with high easy-openability is used as a member for sealing the op...
