The utility model has the characteristics of easy and reliable opening, and high safety.

Description

Draw-free ring style packing tin

Technical field

The utility model relates to a kind of packing jar, especially a kind of seal opening device of tinplate packaging jar.

Background technology

The seal opening device of existing tinplate packaging jar, basically be to adopt draw-ring type, as shown in Figure 1, 2, it by tank body 1 ', loam cake 2 ', draw ring 3 ' and stripper wire 4 ' form, draw ring 3 ' one ends by rivet 21 ' be fixed on loam cake 2 ' on, two strong points 22 of the cooresponding loam cake 2 of the other end ' be provided with '.The production process of seal opening device is: the tank body loam cake is piled up salient point, and--salient point is processed into the rivet blank, and--rivet is finalized the design, and--the process support point--is pressed together on loam cake with draw ring--and processes stripper wire.During use, hook draw ring with finger, then with the thumb press cover, the draw ring of pulling back is peeled off loam cake.Pack jar with the unlatching of draw ring structure, have following defective: 1, production and processing operation is many, cost is high; 2, opened not at that time the draw ring easy fracture; 3,, easily scratch finger in the opening process because the cover rim that is pulled up is sharper; 4, the rivet portion that is positioned at jar and is coated with lacquer inhomogeneously, easily gets rusty in the preservation process.

Summary of the invention

The purpose of this utility model is to provide a kind of packing jar seal opening device simple in structure, processes to be easy to make, and opens safe ready.

The purpose of this utility model is achieved through the following technical solutions:

A kind of draw-free ring style packing tin is made up of tank body, cover and stripper wire, is provided with an annular groove at tank body and cover junction, and stripper wire is positioned at arbitrary position, bottom of groove.

Above-mentioned stripper wire is positioned at the center of bottom portion of groove.

Above-mentioned stripper wire is positioned at bottom portion of groove, apart from 2/3 place, tank body edge.

Behind the packing jar above-mentioned seal opening device of employing,, reduced the production and processing link widely, reduced cost owing to exempt draw ring.The cover surface does not have other annexes, has solved rivet portion depainting and the problem of getting rusty in the prior art.Behind the tank body content filling formation, only need stripper wire of processing, globality is strong, is easy to make.During unlatching, can utilize various tool at one's side,, have convenient, reliable, the safe characteristics of opening as handle for tableware, coin, key or the like.
