Abstract

The utility model provides a sealed bottle lid, includes bottle lid, sealing plug and theftproof ring, and the bottle lid is general bottle lid, and the sealing plug is equipped with the boss for top edge, and the lower part extends the piston body that has protruding ring, in the bottle lid lower part to connect the bridge connection and have the theftproof ring, the curved boss of segmentation uplift on the theftproof ring inner wall anchor ring, from boss to theftproof ring edge, set up bellied strengthening rib along vertical interval. The utility model discloses novel structure, the enhancement that the theftproof ring edge was stood up has played firm effect for the fracture of the bridge of being connected of theftproof ring and bottle lid during the use becomes easy, and the theftproof ring is difficult to be taken away from the bottleneck along with the bottle lid together.

Description

A kind of seal bottle cap

The utility model belongs to a kind of seal bottle cap.

The present seal bottle cap that uses, seal ring and bottle cap are one-body molded, during the bottle cap rotation, seal ring rotates thereupon, and seal ring and bottleneck produce friction, have influenced sealing effectiveness, anti-theft ring that hardness is set is not enough, make that anti-theft ring easily is with from bottleneck together by bottle cap in use.

The purpose of this utility model provides a kind of improved seal bottle cap, make its not only good sealing effect, and bottle cap is separated effectively with anti-theft ring.

The utility model comprises bottle cap, sealing plug and anti-theft ring, bottle cap is the general-duty bottle cap, sealing plug is that top is provided with boss, the bottom is extended with the piston body of protruding ring, each has picked slight fin outward the protruding ring end, boss embeds the depressed area of bottle cap bottom, and withstood by the lug boss of bottle cap inboard and be unlikely to landing, in the bottle cap bottom, be connected with anti-theft ring with connecting bridge, the boss of segmentation protuberance arc on the anti-theft ring inwall anchor ring to the anti-theft ring edge, is provided with the reinforced rib of projection from boss along vertical compartment of terrain.

The utility model novel structure, during the bottle cap rotation, seal ring can not rotate thereupon, seal ring and bottleneck can not produce friction, good sealing effect, the reinforced rib that the anti-theft ring edge is holded up has played firm effect, and the fracture of the connecting bridge of anti-theft ring and bottle cap becomes easily when making use, and anti-theft ring is difficult for being with from bottleneck with bottle cap.

Accompanying drawing 1 is the utility model structure cutaway view.

Accompanying drawing 2 is the utility model running condition structure cutaway view.

As shown in Figure 1, the utility model comprises bottle cap 1 and sealing plug 2, bottle cap 1 is the general-duty bottle cap, sealing plug 2 is provided with boss 2a for top, the bottom is extended with the piston body of protruding ring 2b, protruding ring 2b has outwards picked the end slight fin 2c, and boss 2a embeds the depressed area of bottle cap 1 bottom, and is withstood by the lug boss 1a of bottle cap 1 inboard and be unlikely to landing.Boss 2a cross sectional shape can be circle, oblong or other shape, angle 〉=90 of boss 2a and sealing plug 2 top two sections intersections °, fin 2c can be designed to a slice, also can be designed to one on the other two or multi-disc more, the diameter of protruding ring 2b is more smaller than the internal diameter of bottleneck, in bottle cap 1 bottom, be connected with anti-theft ring 4 with connecting bridge 4b, the boss 4c of segmentation protuberance arc and perk obliquely on the anti-theft ring 4 inwall anchor rings, 4 edges from boss 4c to anti-theft ring are provided with protruding reinforced rib 4a along vertical compartment of terrain.

As shown in Figure 2, when sealing plug 2 is embedded bottle cap 1 bottom, the boss 2a of sealing plug 2 coincide with bottle cap 1 depressed area and contacts, bottle cap 1 top is close at sealing plug 2 tops, bottleneck 3 inwalls are pushed down fin 2c, bottleneck 3 just is fastened among the protruding ring 2b and the space between the boss 2a of sealing plug 2, and the boss 4c on the anti-theft ring inwall tightly withstands bottleneck lug boss lower edge, and reinforced rib (4a) plays the effect of firm anti-theft ring (4).

Claims

1, a kind of seal bottle cap, comprise bottle cap, sealing plug and anti-theft ring, it is characterized in that bottle cap is the general-duty bottle cap, sealing plug is that top is provided with boss, the bottom is extended with the piston body of protruding ring, each has picked slight fin outward the protruding ring end, boss embeds the depressed area of bottle cap bottom, and withstood by the lug boss of bottle cap inboard and be unlikely to landing, in the bottle cap bottom, be connected with anti-theft ring with connecting bridge, the boss of segmentation protuberance arc on the anti-theft ring inwall anchor ring, to the anti-theft ring edge, the reinforced rib of projection is set along vertical compartment of terrain from boss.

2, seal bottle cap according to claim 1, the boss 2a that it is characterized in that sealing plug 2 contacts with bottle cap 1 depressed area is identical, bottle cap 1 top is close at sealing plug 2 tops, bottleneck 3 inwalls are pushed down fin 2c, bottleneck 3 just is fastened among the protruding ring 2b and the space between the boss 2a of sealing plug 2, and the boss 4c on the anti-theft ring inwall tightly withstands bottleneck lug boss lower edge.
