Abstract
The utility model relates to a single-chip plastic bottle cap. An outside sealing ring is arranged on the lateral wall of the bottle cap and is in barb shape with an arc end. The outside sealing ring is matched with the outer wall of the bottle mouth when using, and the inner diameter of the outer sealing ring is smaller than the diameter of the outer wall of the bottle mouth. The outer sealing ring is arranged on the outer ring of the annular cover of the inner top surface and an annular inner stopper is provided with the inner top surface of the bottle cap. The annular inner stopper is arranged on the inner ring of the annular cover and the outer surface of the annular stopper is in arc shape, wherein, the largest diameter of the arc is larger than the inner diameter of the bottle cap matched with the arc. The annular cover is matched with the top surface of the bottle cap when using. The sealing device of the utility model is divided into three parts: the first part is annular inner stopper; the second part is annular cover with plane end to match with the plane of the top of the bottle cap; the third part is an outer sealing device, the barb-shaped structure of which enables that only axially action force is generated during matching the bottle cover with the bottle cap and the bottle cap is evenly loaded at any contact position.
Description
Technical field
The utility model belongs to a kind of bottle cap, particularly to the improvement of Bottle cap structure.
Background technology
Existing a kind of bottle cap, its structure are that the caping inside of bottle cap has ring-like interior plug and triangular-section annulus.Because the outside of this structure is sealed into the triangle annulus, after bottleneck contacted, its contact resistance can sharply strengthen, and it is excessive to cause opening torque ripple, may produce the situation that moment of torsion can't be opened bottle cap too greatly of opening.The outer side seal of triangle is stretched out from the top, and the top wall thickness can produce plastic deformation under situation about being under pressure for a long time, and the seal ability of bottle cap is descended.
Summary of the invention
The utility model overcomes the shortcoming of above-mentioned Bottle cap structure, and a kind of outer side seal that stretches out from sidewall is provided, and makes the unlatching moment of torsion stable, has increased the top seal structure simultaneously, and the sealingly secure of bottle cap is significantly improved.
The purpose of this utility model is achieved in that a kind of single-piece plastic bottle cap, it is characterized in that, and side seal outside the sidewall of bottle cap stretches out, outside leak free is shaped as barb type, and the end is circular-arc, can make bottle cap can enter bottleneck smoothly; Outside seal ring cooperates with the bottleneck outer wall during use, and outside seal ring internal diameter is less than the diameter of bottleneck outer wall.
Be enhanced leaktightness, increase ring-like closedtop at inner top surface; Described outer side seal is arranged on the outer ring of the ring-like closedtop of inner top surface.
Be enhanced leaktightness, the inner top surface of bottle cap also have ring-like in plug, ring-like in plug be positioned at ring-like closedtop inner ring; In ring-like beyond the Great Wall the surface be circular-arc, its circular arc maximum gauge part is greater than the internal diameter of the bottleneck that cooperates with it.
Described ring-like closedtop end is the plane; Ring-like closedtop cooperates with the end face of bottleneck during use.
The utility model compared with prior art has tangible advantage and good effect.The utility model hermetically-sealed construction divides three parts: first is ring-like interior plug, because its surface is circular-arc, its maximum gauge part can well seal like this greater than the internal diameter of the bottleneck that cooperates with it.The end of plug is a circular arc in ring-like, can play good directional tagging, makes bottle cap enter bottleneck smoothly.Second portion is that the end of ring-like closedtop is the plane, just in time cooperates the plane at bottleneck top, has increased seal area effectively and has made seal ability increase greatly.Third part is outer side seal, and its internal diameter is less than the diameter of bottleneck outer wall.The structure of this barb type makes in the engagement process of bottle cap and bottleneck and only produces axial force, and bottleneck all can obtain identical power at any contact position.The outer side seal that stretches out from the bottle cap sidewall that the utility model provides makes that to open moment of torsion stable, has increased the top seal structure simultaneously, and the sealingly secure of bottle cap is significantly improved.

Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is to use the status architecture scheme drawing.
Accompanying drawing 3 is accompanying drawing 2 partial enlarged drawings.
The specific embodiment
See accompanying drawing 1~3.
A kind of single-piece plastic bottle cap, the inner top surface of bottle cap 1 have ring-like in plug 2, ring-like in beyond the Great Wall surface be circular-arc, its circular arc maximum gauge is partly greater than the internal diameter of the bottleneck of cooperation with it.The end of described ring-like interior plug 2 is a fillet, and bottle cap can play good guiding and excessive effect when entering bottleneck like this.
The outer ring of plug 2 is provided with ring-like closedtop 4 in the inner top surface of bottle cap 1 is ring-like; Described ring-like closedtop end is the plane; Ring-like closedtop 4 cooperates with the end face of bottleneck 5 during use.
Outer ring at the ring-like closedtop 4 of bottle cap 1 is provided with the outer side seal 3 of stretching out from sidewall, outer side seal 3 be shaped as barb type, the end is circular-arc, bottle cap can enter bottleneck smoothly like this; Outside seal ring 3 cooperates with bottleneck 5 outer walls during use, and seal ring 3 internal diameters in the outside are less than the diameter of bottleneck outer wall.Because axial force is a tension force, the wall thickness at 3 places of outer side seal simultaneously is the thickest, can avoid the generation of plastic deformation effectively, thereby improve sealing property.
During use, described ring-like in plug 2, ring-like closedtop 4, outer side seal 3 with the cooperation of bottleneck in produce cavity 6 and cavity 7, this structure makes leakage paths produce the twice difference of pressure, and sealing property is greatly improved, and is more more reliable than existing hermetically-sealed construction.
Claims (5)
1. a single-piece plastic bottle cap is characterized in that, side seal outside the sidewall of bottle cap stretches out, and outside leak free is shaped as barb type, and the end is circular-arc; Outside seal ring internal diameter is less than the diameter of bottleneck outer wall.
2. according to the described single-piece plastic bottle cap of claim 1, it is characterized in that described outer side seal is arranged on the outer ring of the ring-like closedtop of inner top surface.
