No drawing clitellum is easy-open bottle lid
(1), technical field
The utility model relates to the easy opening apparatus of a kind of bottle, jar seal cover cap, does not especially have drawing clitellum easy-open bottle lid.
(2), background technology
The key that reduces the can cost is, adopts the recyclable glass bottle can replacement iron sheet can that utilizes again, the high energy consumption iron sheet consumption that minimizing can not recycling.And the key issue of glass bottle can is the leak tightness and the Yi Kaixing of bottle cap, the easy-to-draw glass cap of the band draw ring of seeing in the market, as: the Eaux-De-Vie bottle cap that Asahi beer bottle cap that three and the board sardines glass canned food bottle cap that the Xing Ma of Zhongshan city Food Co., Ltd produces, Japan produce and blue or green Island Mary wine are already produced etc., existing problems are all on this slight draw ring, its cost is too high, again because of centre-of gravity shift that draw ring causes, when the machinery dress covers, directly influence the accurate and stability that bottle cap falls into bottleneck.Thereby many glass bottle cans still adopt unscrewing type iron sheet seal cover cap, but its leak tightness is unsatisfactory, still is subjected to the influence of winter, summer difference variation Re Up shrinkage to leak tightness, especially at high latitude area, summer in the winter temperature difference is (25 ℃----35 ℃) up to 60 ℃, and day and night the temperature difference is about 10 ℃.As: the braised pork with soy sauce glass canned food unscrewing type iron sheet bottle cap that Xiamen Gulong Canned Food Co., Ltd. produces.Yet the good sealing performance glass cap, the difficulty of but uncapping, as: the Yanshan Mountain, Beijing beer glass cap and Shanghai plum forests board Wu Xiang Yellow flower canned fish glass cap.Bottle cap also will reach the positive pressure that bears in the bottle or the requirement of negative pressure, the simple and convenient and financial cost of more essential consideration when satisfying food hygiene and requirements for quality such as fresh-keeping.I " am with pop-top iron sheet cover " patent No. at patent: 00202771.2, and it is characterized in that: handle is drawn in the prolongation on lid edge.Existing problems are all in this slight drawing last, when glass cap in manufacturing process, draw a stress equilibrium that directly influences the garden lid, internal stress is out of shape the local bow of bottle cap, can't satisfy the sealing requirements of bottle cap.
(3), summary of the invention
The purpose of this utility model is that the no drawing clitellum that a kind of i.e. sealing of design is easily opened again covers Yi La .
Till purpose, the utility model adopts following technical scheme, no drawing clitellum easy-open bottle lid comprise lid along last prolongation draw handle, the small gap that eliminates stress, for a short time draw, cross the mechanical scratching wire casing of small gap, the small gap that eliminates stress has been eliminated the internal stress that produces the local bow distortion of bottle cap, constitutes the easy again no drawing clitellum of opening of a kind of i.e. sealing Yi La is covered.
No drawing clitellum is Yi La lid, it draw an extension that covers the edge for iron sheet, and its expansion drawing is the extendible portion at dome edge, this extendible portion is the remaining sides horn scraps that in the past stays during the punching out dome.The design makes full use of the unnecessary in the past leftover bits of this piece, with the open circuited small gap that eliminates stress of mechanical stamping, cross the mechanical scratching wire casing of small gap, the people is focal point of stress and the stress concentration line that causes iron sheet to cover, three that constitute unlatching iron sheet lid are drawn handle for a short time, the prolongation of just iron sheet being covered the edge is drawn and is divided into three to one, for a short time draw in the middle of promptly and right left both sides draw handle for a short time, the iron sheet lid has more its handle that draws when the punching press capping, the small gap that eliminates stress is three and draws for a short time abdicating the space, eliminated the internal stress that produces the local bow distortion of bottle cap, the small gap that eliminates stress is laid in lid along last by the seal request of glass cap.Draw for opening the prolongation arm of force of iron sheet seal cover cap, rise and do leverage; Small gap plays a part to do to eliminate stress; Three are drawn on the tight Zai Yuan of the frame mouth for a short time, constitute one and are divided into three little arc length, and arc length is short more, draw easy drawing back more, play a part to do easy-to-draw.Can be designed to monolateral handle or the bilateral handle that draws of drawing according to opening needs again.When opening lid, earlier the centre is drawn for a short time outwards being pulled upwardly, opening lead-in wire along the delineation wire casing of crossing the indentation, there that eliminates stress pulls open and covers the edge, allow the handle that draws for a short time on right left both sides that the space of individual pull-up is arranged, drawing for a short time left both sides, the right side respectively again outwards being pulled upwardly, open lead-in wire along the delineation wire casing of crossing the indentation, there that eliminates stress again and pull open and cover the edge, allow three to draw for a short time and collection is merged into one draws handle greatly on the caping limit, open lead-in wire along the delineation wire casing together at last and draw brokenly to cover.In fact, only need pull open and cover the edge as small-bore glass caps such as beer, loosen withhold frame tightly at seal ring with the application force on the mouth, one soon opens, thereby reaches that glass cap promptly seals and the easy purpose of unlatching.
Because the no drawing clitellum that adopts in the above-mentioned solution covers Yi La , it can reach the sealing requirements of glass cap very easily, simultaneously can open the iron sheet seal cover cap of withholding on the frame Jin Zai jar mouth easily, replace iron sheet can with the recyclable glass bottle can that utilizes again, minimizing can not recycling the iron sheet consumption of high energy consumption, reduce the can cost.This glass bottle can, the beer of opening conveniently brings convenience to the customer, and great advantage is; Conveniently easily open economical and energy saving.,
(4), description of drawings
Below in conjunction with drawings and embodiments the utility model is made and to further describe.
Fig. 1 is that the utility model does not have drawing clitellum the enclosuring structure section-drawing of Yi La lid.
Fig. 2 is the expansion drawing of iron sheet lid shown in Figure 1.
(5), the specific embodiment
As Fig. 1, shown in Figure 2, when opening lid, earlier the centre is drawn for a short time and outwards be pulled upwardly 4, open lead-in wire 7 along the delineation wire casing of crossing breach 6 places that eliminate stress and pull open lid along 8, what allow right left both sides draws the space that individual pull-up is arranged to 5 for a short time, respectively drawing for a short time of left both sides, the right side outwards is pulled upwardly 5 again, open lead-in wire 7 along the delineation wire casing of crossing breach 6 places that eliminate stress again and pull open lid along 8, allow three to draw for a short time 4,5 collection are merged into one and draw handle greatly on the caping limit, open lead-in wire 7 along the delineation wire casing together at last and draw broken to cover 1.In fact, as small-bore glass caps such as beer, only need pull open lid along 8, loosen and withhold the tightly application force on seal ring 2 He mouths 3 of frame, one soon opens, and promptly seals the purpose of easily opening again thereby reach glass cap 1.
