Abstract
A leakage-proof bottle lid for a drinking water bottle comprises a bottle lid and a soft rubber pad closely contacted with the bottle mouth and arranged in the bottle lid. The leakage-proof bottle lid for the drinking water bottle of the utility model meets the need of sealing and leakage-proofing functions, avoids the leakage of water vapor and eradicates the possible pollution of bottled drinking water basically. Moreover, the structure and the production process of the soft rubber pad are simple, although adding a part, the design of the whole bottle lid and the demand of process precision are reduced greatly, thus reducing the processing difficulty of the product.
Description
Technical field
The utility model relates to a kind of leakproof bottle cap that is used on the cushion, particularly relates to a kind of leakproof bottle cap that uses on the cushion of 18.9 liters of dresses.
Background technology
At present, the cushion bottle cap of 18.9 liters of dresses is mainly made by hard plastics on the market, there is critical defect in design, because himself material is harder, in the contact site between bottle cap and bottleneck can the slit appear because of the error on processing or the size unavoidably, the gas leakage that causes leaking is difficult to the sealing effectiveness that reaches desirable.Such bottle cap proposes excessive demand to working accuracy, has increased difficulty and cost that product is made, usually causes bottle interior potable water contaminated again because of leakage problem, makes water quality guarantee.
The utility model content
The purpose of this utility model is to provide a kind of cushion leakproof bottle cap that can overcome the defective that exists in the prior art, utilize double coloured plastic injection machine disposable filling one deck flexible glue body pad when the bottle cap injection moulding, this flexible glue body pad can with the drinking bottle mouth closed contact, utilize the cooperation of soft or hard storeroom to reach the leakproof purpose.
The purpose of this utility model is achieved in that a kind of cushion leakproof bottle cap, comprises a bottle cap, is provided with a flexible glue body pad with the drinking bottle mouth closed contact in described bottle cap.
Cushion leakproof bottle cap of the present utility model is transformed the structure of conventional bottle cap, one deck flexible glue body pad of in bottle cap, having annotated, satisfy the sealing function requirement of bottle cap well, avoided the aqueous vapor leakage, fundamentally stopped the pollution channel that bottled drinking water may exist.In addition, the structure and the course of processing of this flexible glue body pad are all fairly simple, though added a part, make the design of whole bottle cap and requirement on machining accuracy greatly reduce, so reduced the difficulty of processing and the cost of product on the contrary.
Description of drawings
Fig. 1 is the structural representation of the utility model cushion leakproof bottle cap.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
See also accompanying drawing 1, cushion leakproof bottle cap of the present utility model comprises a bottle cap 1, this bottle cap 1 mainly is made up of roof 11, sidewall 13 and the water outlet 12 that is positioned at this bottle cap 1 inner chamber and is fixed in its roof 11 centers, the utility model utilizes double coloured plastic injection machine injection molded flexible glue body pad 2 in conventional bottle cap, with this leakproof bottle cap fastening on cushion the time, this flexible glue body pad 2 can with the drinking bottle mouth closed contact.The utility model has utilized cooperating of soft packing ring and these two kinds of soft or hard storerooms of hard bottleneck just, has realized good sealed against leakage effect.
Can see that in the embodiment shown in fig. 1 described flexible glue body pad 2 is a circular packing ring, it is fixed on roof 11 inner surfaces of described bottle cap 1, between described water outlet 12 and sidewall 13.The axial height of described flexible glue body pad 2 is suitable substantially with the wall thickness of described bottle cap 1, and its radial width then is slightly larger than axial width, and its cross sectional shape is have two different-thickness step-like, and its inboard thickness is larger than peripheral thickness.
