Abstract

The utility model provides an easy-opened pop can cover. Two close connected round bevels are respectively arranged on the pop can cover surface and the pull-tab with the pressing coupling spindle on the pop can cover surface as the center. The pop can can be easily opened by pushing the pull-tab on the cover surface to make the pull-tab rotate along the round bevel with the pressing coupling spindle as the center , thereby the pull-tab turns up straying away from the pop can, the finger can dive into the pull-tab and hitch the pull-tab.

Description

Rotary inclined-plane departs from cover of pop can

The utility model relates to a kind of pop can container upper cover.

The pop can container is widely used in the packing of beverage and food now, and the opening process of pop can needed for two steps finished, and at first draw ring will be levered up with convenient finger is put into, and scratches draw ring with finger then pop can is opened.In the prior art, because finger is subjected to the area of contact of force direction very little with draw ring, in the process that levers up, finger is easy to slippage, is not easy the draw ring pull-up, sometimes when scratching with finger, damage nail easily, concerning women and children, open more difficultly, have to draw ring to be levered up by other instruments.Inconvenience is arranged when using.There is a kind of patent No. to be: 00250818.4, name is called the patent of " Top cap of pop-top can ", the degree of depth that longitudinal fluting is set under draw ring and has deepened groove, solved the problem of opening difficulty, but since this design when deepening depth of groove, draw ring but still is in the primary plane state, enumerating in the packaging process of cover of pop can, the groove of a last cover of pop can be risen by the draw ring pad of next cover of pop can, not as existing cover of pop can enumerate tight like that, increased the length of packing specification.

In order to overcome the inconvenience of existing cover of pop can when opening, the utility model provide a kind of simple in structure, open easy, easy to use and do not influence the cover of pop can of original packing specification.Its objective is in the following manner and to realize:

Punching press adapter shaft with cover of pop can is the center, the circular sloped surface of two close proximity is set on capping on the cover of pop can and draw ring, punching press adapter shaft consistent with the direction of tilt of circular sloped surface (being the direction that the draw ring fixed end points to the draw ring latch closure), and vertical with the circular sloped surface maintenance.The process of opening pop can is: promote the draw ring latch closure on the Top cap of pop-top can face, making tear-off tin pull ring is that the center rotates along circular sloped surface with the punching press adapter shaft, because there are certain included angle in circular sloped surface and Top cap of pop-top can face, in the process that promotes the draw ring rotation, draw ring can upwards depart from the Top cap of pop-top can face gradually, and shape in an angle between the Top cap of pop-top can face, when rotating to 180 when spending, the angle of this angle reaches maxim, is the twice at circular sloped surface angle of inclination, at this moment, it is maximum that the height that draw ring departs from also reaches, the user is easy to that just finger is put into draw ring and catches on draw ring, catch on draw ring after, to the back rotation draw ring, make draw ring rotate back into former reference position (because the support of finger is arranged, draw ring can not be attached on the Top cap of pop-top can face again), spur draw ring then, pop can is opened.In addition, because the setting of circular sloped surface does not change the cover section conformability of shape up and down, therefore when enumerating packing, can not increase the length of packing specification.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the birds-eye view of the utility model cover of pop can;

Fig. 2 is the A-A place part sectional view of Fig. 1;

To be the utility model cover of pop can promote birds-eye view behind the Rotate 180 degree with draw ring to Fig. 3;

Fig. 4 is the B-B place part sectional view of Fig. 3;

Fig. 5 is that Fig. 1 is enumerated the A-A cutaway view when packing.

Capping, 2. punching press coupling spindle, 3. capping circular sloped surface, 4. draw ring, 5. draw ring latch closure, 6. draw ring circular sloped surface, 7. draw ring fixed end on 1. among the figure.

In Fig. 1, Fig. 2, Fig. 3, Fig. 4, capping circular sloped surface (3) on the last capping (1) is by draw ring circular sloped surface (6) close proximity on punching press coupling spindle (2) and the draw ring (4), two circular sloped surface are concentric with punching press coupling spindle (2) and vertical with punching press coupling spindle (2), the direction of tilt unanimity of two circular sloped surface and punching press coupling spindle (2), the direction of pointing to draw ring latch closure (5) with draw ring fixed end (7) is identical.The angle of inclination of circular sloped surface can be designed to: 5 to 40 degree, present embodiment is designed to the circular sloped surface angle of inclination: 10 degree, the diameter of circular sloped surface is designed to: 6.5mm, thus, can calculate the downward cup depth of circular sloped surface is: Sin (10) * 6.5mm ≈ 1.1mm, this degree of depth will can not influence the intensity of cover of pop can.The length from the connection center-point to latch closure of common draw ring is about 18mm, after draw ring (4) is center Rotate 180 degree with punching press coupling spindle (2), draw ring (4) and last capping (1) are with shape in an angle, this angle is the twice at circular sloped surface angle of inclination, be 20 degree, at this moment, the height that draw ring (4) departs from capping (1) is: Sin (20) * 18mm ≈ 6.2mm, this highly is enough to make the user very easily finger to be put into draw ring latch closure (5), after catching on draw ring latch closure (5), to back rotation draw ring (4), make draw ring (4) rotate back into former reference position [because the support of finger is arranged, draw ring (4) can not be attached on the Top cap of pop-top can face (1) again], spur draw ring (4) then, pop can is opened.

In Fig. 5,, therefore when enumerating packing, can not increase the length of packing specification because the setting of circular sloped surface does not change the cover section conformability of shape up and down.

Claims

1. cover of pop can of the present utility model is made up of capping on the cover (1) and draw ring (4), it is characterized in that on capping on the cover of pop can (1) and draw ring (4), being provided with two circular sloped surface (3), (6), two circular sloped surface are the center with punching press coupling spindle (2), close proximity.

2. cover of pop can according to claim 1 is characterized in that the direction of tilt unanimity of two circular sloped surface and punching press coupling spindle (2), and the direction of pointing to draw ring latch closure (5) with draw ring fixed end (7) is identical.
