Abstract

The utility model relates to a single line tearing type bottle cap which is matched with a glass or plastic cup (bottle), and a packaging container. The utility model is composed of a cap top and a cap body. The inner wall edge of the cap top is provided with a sealing ring. The juncture of the cap top and the cap body is provided with a tearing line. The tearing point of the cap body is provided with a handle. The handle and the cap body are made of the same material. The utility model has the advantages of simple manufacturing procedure, saving materials, and lower cost. When use, the tearing line is pulled apart along the handle point. The cap, the cup, and the bottle are separating, so the use of the utility model is convenient.

Description

Single line is torn bottle cap

The utility model relates to bottle cap, and is suitable supporting with cup (bottle) packing containers such as glass or plastics, is widely used in industries such as food, medicine, chemical industry.

All packing containers such as cup, bottle that relate to generally adopt easy-open end, and therefore, the easy-open end kind of using is a lot of at present, according to the position difference of easily opening manufacturing, can be divided into caping easy-open lid and limit wall easy-open end.The caping easy-open lid generally needs to make trouble by manufacturing procedures such as riveted joints, the expense height, and consumptive material is many; And existing limit wall easy-open end is shaped on two usually and draws back line, and its handle be prefabricated after, continuous through riveting again, so its major defect also is that Fabrication procedure is many, high material consumption, expense height.

The purpose of this utility model provides that a kind of single line tears, and is simple in structure, make laborsaving, the bottle cap that expense is low.

The technical scheme that the utility model single line is torn bottle cap is: be made up of caping and lid, at the caping inner wall edge seal ring arranged, be shaped on tear line at caping with the intersection of lid, there is handle at the lid place of tearing.

Single line of the present utility model is torn bottle cap, and the tear line angle [alpha] of its caping and lid intersection is greater than 180 °, and optimum angle alpha is 200 °～280 °.

Single line of the present utility model is torn bottle cap, and it tears handle is the one that links to each other with lid, and promptly same system becomes.

Single line of the present utility model is torn bottle cap, and the depth of indentation of its tear line is 2/4～3/4 of a lid wall thickness.

The utility model is the lid of the lid, particularly easily openable of a kind of cup or bottle, and its constructional feature is a tear line, and tear the handle with lid be that same block of material is made, and take from extension angle material between the lid, do not need to draw materials in addition make after, go operations such as welding again.Therefore, compared with the prior art, characteristics such as it is simple to have a Fabrication procedure, and material is economized, and expense is low.

Fig. 1 is that the utility model single line is torn the Bottle cap structure scheme drawing;

Fig. 2 is that the utility model single line is torn the bottle cap birds-eye view.

Below in conjunction with Fig. 1-Fig. 2 embodiment of the present utility model is done detailed explanation.

The utility model is to be used for packaging cup or the supporting lids of bottle such as glass or plastics, carry out punching out earlier by same material, when the punch press punching out, utilize and make handle 5 towards the rim charge of part junction, row stretches and makes caping 1 and lid 2 again, intersection at caping 1 and lid 2 is shaped on a tear line 4, tear line can be partial to caping, also can be partial to lid, at the inner wall edge of caping 1 seal ring 3 is arranged.Tear line 4 will have sufficient length, shakes hands during use 5 one to draw, and tear line 4 is drawn back, and lid separates with cup or bottle, and general α angle must be greater than 180 °, and the best is that α is at 200 °～280 °, as about 240 °.The depth of indentation of tear line 4 generally be wall thickness 2/4～3/4 between for good.
