Skirt-blade-type easy-to-pull iron sheet glass cap

Abstract

Disclosed is a skirt-blade-type easy-to-pull iron sheet glass cap. The key to lower can cost is to replace recyclable glass cans with iron sheet cans. The key problems of the glass cans are sealability and easiness in opening of caps. The skirt-blade-type easy-to-pull iron sheet glass cap comprises stress relieving broken notches punched in an equal division manner and capable of increasing original radius R to R1, and is a multi-piece easy-to-pull handle. During uncapping, skirt-blade-type handles 4 are pulled up outwards and pulled broken to an D-cap edge along scored line slotting leads 6 at the positions of the stress relieving notches 5, the skirt-blade-type handles 4 on the left and right sides are pulled up outwards one by one and pulled broken to the D-cap edge along the scored line slotting leads 6, acting force withheld and tightly bound on a sealing ring 2 and an opening 3 is relieved, and the purpose that a glass cap body 1 is sealed and easily opened is achieved. The glass cans and glass canned beers which can be uncapped conveniently bring convenience to consumers. The skirt-blade-type easy-to-pull iron sheet glass cap is comparable to a plastic cap in economy and easiness in opening, is unaffected by plasticizers, and has a destructive anti-counterfeiting function and tremendous market.

Description

(1) Technical field [0001] The invention relates to an easy-opening device for sealing caps of bottles and cans, in particular to a skirt-type easy-to-pull iron glass bottle cap. (two), background technology [0002] The key to reducing the cost of cans is to use recyclable glass bottled cans instead of tin cans to reduce the amount of non-recyclable and energy-intensive tin cans. The key problem of glass bottled cans is the sealing and easy opening of the bottle cap. The easy-to-pull glass bottle caps with pull rings seen on the market at present, such as: Sanhe brand sardine glass produced by Zhongshan Xingma Food Co., Ltd. Can bottle caps, Asahi beer bottle caps produced in Japan, and fruit wine bottle caps produced by Qingdao Mary Wine Co., Ltd., all have problems with the small ring. Its cost is too high, and the center of gravity is shifted due to the ring When the cap is mechanically installed, it directly affects the accuracy and stability of the cap falling into th...

Problems solved by technology

The problem lies in the small handle. When the glass bottle cap is in the process of making, the handle directly affects the stress balance of the round cap. The internal stress makes the bottle cap partially bow and deform, which cannot meet the sealing requirements of the bottle cap.
