CN86209837U - Easy openable glass can cover - Google Patents

Abstract

The utility model discloses an easy opening glass can cover. The middle part inside the cover body of the easy opening glass can cover is provided with two pressing traces or carving traces with certain depth. A pulling ring is fixed on the middle of the two pressing (carving) traces. According to the different penetrating ways of the pressing (carving) traces, the pulling ring can be fixed on the left flange of the edge of the cover body and can also be fixed on the position in the range of a sealing ring of the cover body. When people eat cans, as long as the pulling ring is pulled along the direction of the pressing (carving) traces, the can covers can be conveniently opened.

Description

Easy openable glass can cover

The utility model relates to a kind of glass bottle can bottle cap that easily draws back.

For the unlatching problem of iron-clad tin can, existing at present a kind of simple and feasible method promptly winds off with a key, but for the unlatching problem of glass bottle can bottle cap, so far incomparable perfect method still.The CN-ZL85200075 patent has announced that a kind of feasible method is with traditional can opening key, along the continuous scrolling of capping, follows two impressions and winds off.The method of volume is very suitable when tank body is circular arc type, and is not too convenient when being used for cover and being the plane.

At the problems referred to above, the utility model proposes a kind of glass bottle can bottle cap that easily draws back just.

The utility model is achieved in that when punching out can bottle cap on capping punching press twice have the impression of certain depth, perhaps stamp out the indentation that twice have certain depth with icking tool, and make these twice press (quarters) trace to be positioned in the middle part of the inside of bottle cap lid.A kind of is whole penetration type, and promptly twice press (quarter) trace to run through whole lid; A kind of is the part penetration type, be that twice press (quarter) trace one end to run through lid one lateral edges, the other end then terminates in lid opposite side involution circle with the lining, press (quarter) trace termination along stamping out semi-circular pressure (quarter) trace equally two simultaneously, press (quarter) trace to join with original twice with the vertical direction of two pressure (quarter) traces; Another is the middle part penetration type, and promptly twice press (quarter) trace to run through the involution circle with the lining.Run through mode for integral body, during the punching out lid, reserve a flange, on this flange, weld or rivet a draw ring again in the lid edge that is positioned at twice pressure (quarter) trace middle part; Run through mode for part, but more solito punching out, between semicircle type pressure (quarter) trace and involution circle, run through and press (quarter) trace together, for strengthening the folding quality of can bottle cap, run through bottle cap involution circle and establish several convex tendons with two pressures (quarter) trace outside of lining, burn-oning or rivet a draw ring in pressure (quarter) trace end on good lid gets final product.

Because said structure feature of the present utility model during canned food, only needs can easily bottle cap be opened along the direction pulling draw ring of pressing (quarter) trace.

Fig. 1 is an embodiment of the present utility model.Among the figure: (1) is lid, and (2) for pressing (quarter) trace, (3) are flange, and (4) are draw ring.

Fig. 2 is another embodiment of the present utility model.(1) is lid among the figure, and (2) for pressing (quarter) trace, (3) are the involution circle, and (4) are draw ring.

Fig. 3 is another embodiment of the present utility model.(1) is lid among the figure, and (2) for pressing (quarter) trace, (3) are the involution circle, and (4) are draw ring, and (5) are convex tendon.

Claims (6)

1, a kind of glass bottle can bottle cap that easily draws back is characterized in that middle part, lid the inside has twice to have the impression or the indentation (or the combination of the two) of certain depth, is fixed with a draw ring on the lid in the middle of twice are pressed (quarter) trace;

2, the glass bottle can bottle cap that easily draws back according to claim 1 is characterized in that twice pressure (quarter) trace runs through whole lid, is positioned at twice and presses the middle lid edge of (quarter) trace that one flange is arranged, and draw ring welds or is riveted on the flange;

3, the glass bottle can bottle cap that easily draws back according to claim 1, it is characterized in that twice pressure (quarter) trace one end runs through lid one lateral edges, the other end then terminates in lid opposite side involution circle with the lining, press (quarter) trace termination along pressing the vertical direction of (quarter) trace to have pressure (quarter) trace of semicircle and original twice pressure (quarter) trace to join draw ring welding or riveted joint (or the combination of the two) pressure (quarter) trace end on lid two simultaneously with two;

4, the glass bottle can bottle cap that easily draws back according to claim 3 is characterized in that twice pressure (quarter) trace runs through lid two ends involution circle with the lining;

5, the glass canned food bottle cap that easily draws back according to claim 3 is characterized in that running through between semicircle type pressure (quarter) trace and the involution circle and presses (quarter) trace together;

6, the glass bottle can bottle cap that easily draws back according to claim 4 is characterized in that running through the involution circle and presses some convex tendons of (quarter) trace outside distribution with the twice of lining.
