Abstract

The utility model relates to a special sealing ring for the bottle cover with the lining of the guide rail. The utility model comprises a rubber ring body made of colloidal material and two semi-circular hard linings, the groove ends of the hard linings and the convex end arranged on the inner edge of the rubber ring body are sheathed and formed into a washer, the washer is placed on the edge of the groove arranged on the neck of a bottle cap, the sealability is good, the washer and the bottle cap are screwed closed without deformation and desquamation, and the durability is high.

Description

Sealing ring special for bottle cover

The utility model relates to a kind of band and presses to the bearing ring seal that is bordering on radial face on the element, especially acts on the special-purpose tightening seal washer on the bottle cap.

The function of bottle cap closes the function except screwing, and also has a most important function, and promptly leak tightness wants high, if for example the cap leak tightness is not high, its in-to-in hot water just can not keep higher temperature.And the key of sealing property just is the packing ring quality on the bottle cap, that is to say, is arranged at packing ring on the bottle cap when better, and leak tightness is preferable, otherwise, being arranged on packing ring on the bottle cap when relatively poor, its leak tightness is just poor.

Packing ring such as Fig. 1 commonly used, it makes rubber-like round body by a rubber-like material, so be used in when screwing on the bottle cap, under bottle cap friction influence of shear force, be easy to generate torsional deflection as shown in Figure 2, so that can't bring into play excellent sealing performance, thereby influence the temperature or the pressure of liquid in containers.

The purpose of this utility model is to propose a kind of bottle cap special washer, it is when being subjected to external compression, and the liner guide rail is that hard material is not yielding, still be nested in turn in the recessed edge groove of bottle cap neck and not fragile, come off, thereby it is keep better sealing property, and durable in use.

The utility model is achieved in that a kind of bottle cap special washer of tool guide rail liner, comprise the cushion rubber body 2 that colloidal materials is made, hardness liner 3,31, it is characterized in that: the inner edge section of cushion rubber body 2 is outer gibbosity and has a protruding end 6, the semicircle that hard liner 1 separates for two-section, the semicircle 3,31 that two-section separates is positioned on the groove edge 5 on bottle cap neck top ringwise, this hard liner has a groove ends 7, and the protruding end 6 on the cushion rubber body inner edge surface is nested on the groove ends 7 of hard liner 3,31.

The utility model is simple in structure, and good sealing effect is to serve popular excellent product.

Fig. 1 is existing gasket of bottle lid structural representation.

Fig. 2 produces the situation of distortion for having now when gasket of bottle lid and bottle cap screw.

Fig. 3 is the utility model STRUCTURE DECOMPOSITION figure.

Fig. 5 is the utility model hard liner section structure scheme drawing.

Fig. 6 is the utility model textural association figure.

Fig. 7,8 is embodiment.

Now further narrate the utility model in conjunction with the accompanying drawings.

Referring to Fig. 3-8: the utility model is by a cushion rubber body 2 and the semi-round hard liner 3,31 of two-section, wherein the inner edge Section Design of this cushion rubber body 2 is and is similar to male type and has a protruding end 6, the outer rim section of hard liner 3,31 is arranged to be similar to ring-like and is had a groove ends 7, the groove ends 7 of this hard liner 3,31 is nested on the inner edge surface of cushion rubber body 2, constitutes a gasket of bottle lid with inner lining structure thus.During combination, on earlier that semi-round hard liner 3,31 inner edges of two-section are the relative groove edge 5 that is seated in bottle cap 4 neck tops, again with inner edge jag 6 snares of glue containment body 2 in the groove ends 7 of these two hard liner, 3,31 outer edge surfaces, can make bottle cap be taken in and one have the hard liner and on-deformable packing ring, when the friction shearing that although packing ring is screwed by bottle cap 4 during use produces, also unlikely being distorted reaches preferable sealing property.
