Problems solved by technology

[0007] For example, the easy-opening lid disclosed in Japanese Patent Application Laid-Open No. 11-011526 aims to obtain excellent easy-opening and protective properties and improve internal pressure resistance strength. A heat-sealable laminate is bonded to a material (thermoplastic resin) through an adhesive layer. The adhesive strength of the laminate is higher than the interlayer adhesive strength of the laminate, and the tensile strength of the adhesive layer is higher than that low bond strength

Abstract

The present invention relates to an easy-open container cap comprising: a cap member having a preformed opening; With a pull tab, the pull tab for unsealing includes a flexible pull tab member and a plug member that is formed to be bonded to the pull tab member and can be fitted with the opening of the aforementioned cover member, and the aforementioned flexible pull tab The member is releasably attached and fixed to the opening peripheral portion of the cover member. Therefore, there is an advantage that good effects can be obtained, that is, having resealability, that is, the temporary reseal that temporarily closes the opening once unsealed can be repeatedly performed, and has good resealability when the sealability and unsealability are good. Indication function, easy opening, etc.

Description

technical field [0001] The present invention relates to an easy-opening container cap and a manufacturing method thereof, in particular to an easy-opening container cap which is a partial-opening type and has reclosability, that is, can perform temporary reclosing such as temporarily reclosing the opening once opened. Caps for sexual containers and methods of making the same. Background technique [0002] Easy-open lids (easy-open lids) are widely used as food container lids for food cans and beverage cans. Among them, there are partial opening types that are mainly used as lids for beverage cans containing various beverages such as cola, beer, and fruit juice. Container caps, and fully open container caps that are mainly used as lids for food cans such as cans, instant noodles, and fast food. [0003] The partial opening type container cover is further divided into the pull-tab detachment type in which the easy-to-break tab is completely separated from the container cover ...
