Abstract
The utility model provides a kind of silica gel lid, comprise a hollow cylindrical lid, described lid one end open, the other end is closed, the cross-sectional area of described lid reduces gradually from closed end to open end, described lid portion inside has a cross-sectional plane to be the circular groove of circular arc along the edge of closed end, described lid portion inside is installed with a hollow cylindrical seal ring extended from closed end to open end, the inwall interval of described seal ring and described lid is arranged, space between described seal ring and described lid inwall forms the annular seal space for sealing bottleneck, described annular seal space is communicated with described circular groove.Because the cross-sectional area of lid reduces gradually from closed end to open end, thus lid can be made tightly to be wrapped up by bottleneck, improve the leak tightness between lid and bottleneck; Because the circular groove of lid portion inside coordinates with the flange of bottle mouth position, therefore both can improve the leak tightness between lid and bottleneck, and can also prevent lid from coming off from bottleneck.
Description
Technical field
The utility model relates to a kind of silica gel lid.
Background technology
At present, when existing bottle adopts silica gel lid to seal, the leak tightness of silica gel lid and bottleneck is poor, and silica gel lid is also easy to come off from bottleneck, causes seal failure.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, the silica gel lid that provide a kind of good airproof performance with bottleneck, can not come off from bottleneck.
The utility model realizes like this, a kind of silica gel lid, comprise a hollow cylindrical lid, described lid one end open, the other end is closed, the cross-sectional area of described lid reduces gradually from closed end to open end, described lid portion inside has a cross-sectional plane to be the circular groove of circular arc along the edge of closed end, described lid portion inside is installed with a hollow cylindrical seal ring extended from closed end to open end, the inwall interval of described seal ring and described lid is arranged, space between described seal ring and described lid inwall forms the annular seal space for sealing bottleneck, described annular seal space is communicated with described circular groove.
Particularly, described seal ring extends to the near middle of described lid.
Further, the open end of described seal ring is provided with chamfering.
Particularly, described lid and described seal ring adopt silica gel one-body molded.
Because the cross-sectional area of lid reduces gradually from closed end to open end, thus lid can be made tightly to be wrapped up by bottleneck, improve the leak tightness between lid and bottleneck; Because the circular groove of lid portion inside coordinates with the flange of bottle mouth position, therefore both can improve the leak tightness between lid and bottleneck, and can also prevent lid from coming off from bottleneck.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical solution of the utility model, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the cutaway view of the silica gel lid that the utility model embodiment provides.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
As shown in Figure 1, a kind of silica gel lid that the utility model embodiment provides, comprise a hollow cylindrical lid 1, lid 1 one end open, the other end are closed, the cross-sectional area of lid 1 reduces gradually from closed end to open end, namely the open end of lid 1 inwardly shrinks, thus lid 1 can be made tightly to be wrapped up by bottleneck (not shown), improves the leak tightness between lid 1 and bottleneck;
Lid 1 inside has a cross-sectional plane to be the circular groove 2 of circular arc along the edge of closed end, and circular groove 2, for coordinating with the flange of bottle mouth position, both can improve the leak tightness between lid 1 and bottleneck, can also prevent lid 1 from coming off from bottleneck;
Lid 1 inside is installed with a hollow cylindrical seal ring 3 extended from closed end to open end, seal ring 3 extends to the near middle of lid 1, lid 1 and seal ring 3 adopt silica gel one-body molded, the inwall interval of seal ring 3 and lid 1 is arranged, space between seal ring 3 and lid 1 inwall forms the annular seal space 4 for sealing bottleneck, annular seal space 4 is communicated with circular groove 2, the open end of seal ring 3 is also provided with chamfering 31, and chamfering 31 can so that bottleneck successfully enters annular seal space 4 from the open end of seal ring 3.
When adopting silica gel lid of the present utility model to carry out sealing bottle, first bottleneck is filled in annular seal space 4 from the chamfering 31 of the open end of seal ring 3, then bottleneck is continued to fill in inwards, until bottleneck enters circular groove 2, now the flange of bottle mouth position coordinates with circular groove 2, namely completes being sealed and matched of silica gel lid and bottle.
The above is preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
Claims (4)
