Abstract

The utility model relates to the field of a sealing member for bottled bearing liquid, which is a bottle cap with a pull ring and a positioning bulge and is composed of a bottle cap and the pull ring. The positioning bulge makes the pull ring smoothly transit on the bottle cap, and a clamping phenomenon between two bottle caps is hard to cause. An integral cover rivet, the positioning bulge and a cutting line with an indentation are arranged on the bottle cap. A connecting hole of the pull ring and the integral cover rivet on the bottle cap are formed by being punched and riveted. When the bottle cap is opened, the cutting line with the indentation is pulled and broken by a hook arc in a notch of the pull ring by using the bottle cap as a fulcrum, the bottle cap is disengaged from a bottle mouth, and the purposes of pressure reducing, safety, easy pull and cover unloading are realized. The utility model is a quite ideal bottle cap at present.

Description

Locate protruding draw ring bottle cap

The utility model relates to the bottled closure member of pressure-bearing liquid field, is a kind of protruding draw ring bottle cap in location that has.

At present, most crown cap, the especially beer bottle caps of adopting of the bottled sealing of pressure-bearing liquid are blasted and the human casualty accident that produces when opening summer, cause the concern of the whole society.People thirst for a kind of both easy-to-draw safety, and the bottle cap that can meet the flow production line operation again comes out.

The purpose of this utility model is, provide a kind of location protruding draw ring bottle cap, to solve the bottle cap of pressure-bearing liquid, not easy-to-draw, feel unwell complete, or do not meet the contradiction of flow production line operation, make the design-calculated bottle cap have easy-to-draw, safety, be fit to the flow production line operation, and the Bottle cap structure design batch production requirement that can have high input again.

Above-mentioned purpose is achieved in that it is provided with bottle cap and draw ring, and it is protruding to be provided with the lid riveting and the location that belong to one with it together in the bottle cap, and the tangent line of band impression, the lid riveting punching out riveted joint of the connecting bore of draw ring and bottle cap; Draw ring is provided with and colludes arc, and the extension two ends of colluding arc are provided with breach.Collude when lifting ring, the arc that colludes in the draw ring breach is fulcrum with the bottle cap, and the tangent line of broken belt impression makes bottle cap break away from bottleneck, realizes decompression, safe, easy-to-draw, the purpose of unloading lid.

Its advantage is the reasonable in design of bottle cap, can seal and pressure bearing, again can be easy-to-draw safely, and be the ideal substitute of like product.

Sequence number: 1, draw ring, 2, bottle cap, 3, tangent line, 4, the location is protruding, 5, collude arc, 6, breach, 7, the lid riveting.

Referring now to top view, in conjunction with principle of work its feature is further narrated: locating protruding draw ring bottle cap is a kind of protruding draw ring bottle cap in location that has, it is made up of bottle cap 2 and draw ring 1 two parts, and bottle cap 2 is provided with the tangent line 3 that the riveting 7 of disjunctor lid, location are protruding 4, have impression; The disjunctor lid riveting 7 that is provided with on draw ring 1 connecting bore and the bottle cap 2 is that the punching press riveted joint forms.Lid riveting 7 shown in Fig. 6 is the states of not riveting as yet.Fig. 4 is the state that bottle cap 2 and draw ring 1 punching press riveted joint finish.One end of draw ring 1 is to collude arc to be embedded in the riveting neck that covers riveting 7, and the other end colludes arc and is clamped in location protruding 4.Bottle cap 2 is provided with the tangent line of two place's band impressions.One tangent line 3 is 45～50 ° with the circular arc α angle of bottle cap 2, and its two tangent line is located at and covers riveting 7 inboard sides; It is protruding 4 to be provided with the location at the corresponding surface of this tangent line, and draw ring 1, the two ends of colluding arc 5 extensions are provided with breach 6.Locate protruding 4 and make draw ring 1 excessively slick and sly on bottle cap 2, be difficult for causing stuck phenomenon between two bottle caps in flow production line, and influence ordinary production.

Excavate in the draw ring outer rim earlier before the uncork of this bottle cap, forefinger is put in the draw ring hole the draw ring pull-up.α angle by 50 semicircles of Φ in the draw ring and circular arc is that 48 ° two flat-cut lines are taken advantage of a situation and pull-up, and a tangent line is all broken, and another tangent line end also leaves 5 millimeters distances and can not break.Impel this lid overwhelming majority to break away from bottleneck.In order to prevent the bottle cap that explodes, about 0.16 millimeter of the tangent line position degree of depth, the maximum bearing pressure 1.6MPa of bottle, and the bottle cap maximum to bear pressure be 1.2MPa.Therefore, just play lid during the bottle cap superpressure in advance automatically, prevent the generation of bottle explosion accident.As behind the beer filling in the high-temperature sterilization process temperature can reach 85 ℃, bottle cap bears pressure 0.8MPa～1.2MPa, 82 ℃～85 ℃ of bearing temperatures, just bottle cap is withstand voltage, high temperature resistant all is lower than beer bottle, it is the first road executive item of safety precaution.Therefore, be present safe, easy-to-draw a kind of bottle cap, have certain application value.
