Description

A kind of shock resistance anti-theft bottle cap
Technical field
The present invention relates to a kind of bottle cap, particularly a kind of shock resistance anti-theft bottle cap.
Background technology
Existing Large Copacity bottle (such as 4L oil bottle, 4L mineral water bottle etc.) the safety girdle of bottle cap be generally designed to saw-toothed blade formula or button bit formula theft-prevention structure, the safety girdle of bottle cap is stressed is on each bearing surface separated, easily cause unbalance stress, when bottle interior produces larger stamping press upwards to bottle cap, the safety girdle distortion on bottle cap is easily made to loosen, even safety girdle departs from from the nest of bottle, especially in transportation, in Large Copacity bottle, the liquid of splendid attire easily produces stronger impulsive force to bottle cap, and between each bottle, clash into mutually the pressure larger to bottle cap generation, the safety girdle distortion covered all easily is caused to loosen or get loose, bottle cap is loosened and causes leak of liquid in bottle, more seriously there will be bottle cap by the phenomenon of swarming in.
Summary of the invention
For the above-mentioned problems in the prior art, technical matters to be solved by this invention is to provide a kind of shock resistance anti-theft bottle cap, it is easy to assemble fast, effortlessly, can bear from bottle interior stamping press upwards, avoid occurring bottle cap loosen or bottle cap by the phenomenon of swarming in, there is good puncture energy and theftproof performance.
Technical scheme of the present invention is as follows: a kind of shock resistance anti-theft bottle cap, comprise the female body of the bottle lid of band, with the safety girdle of described body of the bottle lid integrated injection molding, ring cutting gap is provided with between described body of the bottle lid and safety girdle, described ring cutting gap is equidistantly provided with the connecting bridge that several connect body of the bottle lid and safety girdle, also comprise the antitheft shirt rim of annular with body of the bottle lid and safety girdle integrated injection molding, the antitheft shirt rim of described annular is connected to described safety girdle edge turningly, the antitheft shirt rim of described annular forms a circle flange in the inner side of described safety girdle and both connect in obtuse angle, the interior ring of the antitheft shirt rim of annular is near bottle cap line of centers, the external toroidal ring of annular antitheft shirt rim is then connected with described safety girdle, the surface deviating from bottle cap inner chamber in the antitheft shirt rim of described annular forms wedge shaped projection spaced apart, thinner wall section between two adjacent wedge shaped projection, described wedge shaped projection is wedge shape bulge-structure, the high-end close described interior ring of this wedge shape bulge-structure, the low side of wedge shape bulge-structure is near described external toroidal ring.
Annular antitheft shirt rim uneven thickness etc., when turning over annular antitheft shirt rim, thinner wall section is easily stretched, and makes the contracting tension degree of annular antitheft shirt rim little, easy flange, assemble smooth and easy; When tightening bottle cap, good guiding, correcting effect can be played in annular antitheft shirt rim, and bottle cap is easily tightened on bottle; Bottle cap is tightened to put in place and is arranged on after on bottle, when bottle cap is subject to bottle interior liquid stamping press upwards, the antitheft shirt rim of annular props up the nest of bottle, the antitheft shirt rim of annular and safety girdle form trigonum, the antitheft shirt rim of annular is stuck in below nest with pyrometric cone form, triangular structure is stablized, and body of the bottle lid not easily produces distortion or loosens; And two high-end bights of the wedge shape projection of wedge shaped projection are against on bottleneck, the inside angle part near safety girdle is against on nest, and the outer corners away from safety girdle is against on the bottleneck outer wall below nest, also forms triangular structure; When antitheft shirt rim be subject to nest pressure and for overturning downwards time, namely the angle of antitheft shirt rim and safety girdle has when becoming large trend, high-end outer corners because of wedge shape projection is against on bottleneck outer wall, and make antitheft shirt rim cannot be out of shape upset, the antitheft shirt rim of annular and safety girdle uniform force, effectively can avoid occurring that bottle cap loosens makes leak of liquid or bottle cap in bottle by the phenomenon of swarming in, have good puncture energy and theftproof performance.
Further, the thickness of the protruding low side of wedge shape of described wedge shaped projection is identical with the thickness of described thinner wall section, and the protruding high-end thickness of wedge shape of wedge shaped projection is 2-3 times of the thickness of described thinner wall section.
Further, described safety girdle is tapered, and the thickness bottom safety girdle is 1.2-1.5 times of top thickness, makes safety girdle can bear larger impulsive force, and not yielding or damage strengthens puncture energy and the theftproof performance of bottle cap.
Further, the lateral wall of described body of the bottle lid is provided with several axially parallel and anti-skidding muscle of projection uniformly at intervals, distance between adjacent anti-skidding muscle root is less than the width of single anti-skidding muscle root, and the anti-skidding muscle of setting can increase the grip of bottle cap, is convenient to laborsaving assembling bottle cap.
Further, the negative thread of described body of the bottle lid is two pitch threads, can reduce knob stroke, be convenient to rapid-assembling bottle cap.
Further, when described body of the bottle lid opening down, the ridge ramp of described negative thread and the angle of horizontal surface are 37-43 degree, the angle of ridge lower inclined plane and horizontal surface is 12-18 degree, and the ridge top of described negative thread and ridge root are rounding transition, the inclination angle on inclined-plane, ridge both sides is larger, body of the bottle lid is easy to the demoulding when withdrawing pattern, and when tightening bottle cap, friction force is less, when bottle cap is subject to greater impact power, stress can be avoided to concentrate and to cause ridge be out of shape the sliding tooth of appearance or collapse dental phenomenon, contribute to the puncture energy improving bottle cap.
The invention has the beneficial effects as follows: the present invention is easy to assemble fast, effortlessly, after tightening bottle cap, the antitheft shirt rim of annular and safety girdle form stable trigonum, the antitheft shirt rim of annular is stuck in nest with pyrometric cone form, when bottle cap is subject to bottle interior stamping press upwards, annular antitheft shirt rim and safety girdle uniform force, body of the bottle lid not easily produces distortion or loosens, can effectively avoid occurring bottle cap loosen or bottle cap by the phenomenon of swarming in, there is good puncture energy and theftproof performance.
