Abstract
The utility model discloses a self-relieving pressure easy opening tin cover with guaranteed quality. The self-relieving pressure easy opening tin cover with guaranteed quality is composed of a ring hoop, a sealing ring and a bottle cover which are in turn placed on the outer wall of a bottle mouth from outside to inside. The lower edge of the bottle cover is contacted with a sealing line of the bottle mouth. The connection of the two free ends of the ring hoop is spot welding overlapping connection, and one free end of the ring hoop is provided with a pulling ring. When tins are sealed, the ring hoop and the sealing ring are forced to metamorphose to cling to and block up the gap between the lower edge of the bottle cap and the sealing line of the bottle mouth, so the goal of keeping vacuum is achieved. The pulling ring is pulled only with little more force, the ring hoop can be pulled apart from the spot welding position, and the sealing ring automatically falls off. Then the air gets into the bottle to automatically relieve pressure, so the tin can be easily opened. The self-relieving pressure easy opening tin cover with guaranteed quality is used for glass bottle tins.
Description
The utility model belongs to the improvement of glass bottle can ends.
Sealing of existing seal-rolling glass canned food is to put into rubber grommet at the bottle cap inner edge always, by roller pushing bottle cap, force bottle cap to be close to the bottleneck outer wall and make its sealing with the rubber grommet of sealing distortion, and its good seal performance, but it is very difficult to open bottle cap when edible.Easily open glass jar and the patent No. is 86206185 hoop button, it is intended that wants to reach the purpose of easily opening.But because of vacuum in the jar, bottle cap is subjected to the effect of bar pressure, and in fact opens not a duck soup.This proprietary design sealing property is bad in addition.Therefore, out of reach leak free purpose in reality is implemented, this does not have practical significance for the vacuum-packed can of needs.Number of patent application is the utility model of the empty easy open can skull of a kind of fidelity of 215382.X in addition, though have lot of advantages, but bottle cap is except that being subjected to the bar pressure effect when opening, and also will add the tight power that upper bottle cover produced the bottleneck outer wall when sealing and the friction force of seal ring.Therefore, difficult more when opening bottle cap.Though this can ends can keep vacuum, easily to open still very difficultly, this is that reaching easily to open is also not have practical significance the improved type can ends of purpose.
The purpose of this utility model is exactly will overcome the problems referred to above a kind of glass bottle and jar skull that can keep the higher degree of vacuum of can easily open really again is provided.
Formation of the present utility model at first is that bottle cap (3) is covered bottleneck, and the lower rim of its bottle cap (3) is shelved on the glass bottle sealing line (6); Adopt high frequency spot welded then, the hoop (1) that two free ends that 2 overlap joints of spot welding are made with sheet tin form, and in hoop (1), place seal ring (2), both are placed on the outer wall of bottle cap (3) and glass bottle opening to make it.During sealed cans, seaming roll pushes from outside to inside, force both distortion of hoop (1) and seal ring (2) and be close to bottle cap (3) the lower edge outside, make the lower edge inboard be close to the bottleneck outer wall simultaneously, seal ring (2) blocks place, the slit between bottle cap (3) lower rim and the glass bottle sealing line (6) when distortion, thereby reaches the leak free purpose.Set up draw ring (5) in a free termination of its hoop (1) at last.When edible, only slightly firmly pull draw ring (5), then hoop (1) is promptly torn from spot welding, and seal ring (2) comes off thereupon, and outside air is entered in the bottle by the place, slit rapidly, thereby makes bottle cap (3) pressure equilibrium, reaches the purpose of easily opening.
Advantage of the present utility model: 1. simple in structure, reasonable in design, good airproof performance has higher degree of vacuum, the quality of maintenance food that can the long period.2. no matter old the children and disabled person just can be opened bottle cap as long as exert oneself slightly, has really reached the purpose of easily opening.
Description of drawings:
Fig. 1 is the assembly drawing before the can-food sealing.
Fig. 2 is bottle cap assembly parts and bottleneck local section enlarged drawing.
Fig. 3 is a hoop spot welding overlapped points section profile.
With reference to Fig. 1, as embodiment of the present utility model, it is assembled into by hoop (1), seal ring (2), bottle cap (3), hoop two free end solder joints (4), draw ring (5), glass bottle sealing line (6), glass bottle (7).Be not difficult to find out that the utility model is simple in structure, do not have special production equipment and technological requirement, can be in existing can manufacturer, utilize the enforcement of going into operation of existing sealed cans machinery and operative technique.
Claims (2)
1, guarantees the quality to disappear voluntarily and press the easy open can skull to form by hoop (1), seal ring (2), bottle cap (3), it is characterized in that described hoop (1), seal ring (2), bottle cap (3) overlap before sealed cans successively from outside to inside is placed on the bottleneck outer wall, and its bottle cap (3) lower rim contacts with bottle mouth sealing line (6).
2, can ends as claimed in claim 1 is characterized in that hoop (1) two free end adopts the spot welding overlap joint to form, and a free end wherein has draw ring (5).
