Further, movable axis comprises elastic body installation portion and base connecting portion, and base connecting portion is formed with groove, and one end of base is formed with protrusion, and described protrusion is connected to form coupling sealing with described groove.
Elongated top comprises the tapered portion that narrows gradually towards fluid egress point and the cylindrical bottom portion with bottleneck connecting portion adjacency, and cylindrical bottom portion is formed with negative thread.
Base has cylinder form and is formed with outside thread, and the outside thread of base engages with the negative thread of cylindrical bottom portion, and the other end of base is resisted against on bottleneck.
Further, bottleneck connecting portion is hollow cylinder, and described cylinder forms has negative thread to be connected with the outside thread of bottleneck, thereby bottle cap is connected on bottle.
Preferably, the outside face on elongated top has protruding card article, and the open end of over cap has draw-in groove, and protruding card article is stuck in draw-in groove so that over cap is connected on seal cover cap.
Alternatively, elastic body is spring.
Preferably, over cap is transparency cover.
Alternatively, elongated top and bottleneck connecting portion are integrally formed.
Compared with conventional bottle cap, automatic airtight bottle cap of the present utility model is adapted to all fluids except adhesives, and has excellent leakproofness, can prevent volatilize fluid, makes moist and be oxidized, and is therefore particularly useful for the fluid of the easy moisture absorptions such as phosphatide.In addition, automatic airtight bottle cap of the present utility model can be opened automatically with sealing fluid outlet and without hand, mouth or other object contact seal cover cap, therefore clean health and reusable.Therefore, the also suitable lid as cruet for kitchen use and oil can of the utility model.
Accompanying drawing explanation
Above-mentioned and other side of the present utility model and feature are by from presenting the explanation of embodiment is clear below in conjunction with accompanying drawing, wherein:
Fig. 1 is according to the cut-away view of the automatic airtight bottle cap of the utility model embodiment;
Fig. 2 is the exploded perspective view of the automatic airtight bottle cap shown in Fig. 1; And
Fig. 3 is the block diagram of show events axle and base schematically.
The specific embodiment
Describe with reference to the accompanying drawings illustrative of the present utility model, non-limiting example in detail, to being further described according to automatic airtight bottle cap of the present utility model.
Fig. 1 has shown that, according to the inner structure of the automatic airtight bottle cap of the utility model embodiment, the bottle cap of described automatic airtight comprises over cap 1 and seal cover cap 2.Seal cover cap 2 has and is connected to the bottleneck connecting portion 21 of bottleneck and hollow elongated top 22, and the top on elongated top 22 has at least one fluid egress point 23.For example, the top on elongated top 22 has multiple fluid egress points 23, as shown in Figure 2.Preferably, elongated top 22 and bottleneck connecting portion 21 are integrally formed.Over cap 1 is enclosed within on elongated top 22, to prevent from polluting seal cover cap.Preferably, over cap 1 is transparency cover.
According to the utility model, in seal cover cap 2, be provided with the start-stop system for allowing and stoping fluid to flow out.Start-stop system comprises elastic body 3, movable axis 4 and base 5.Elastic body 3 is enclosed within on movable axis 4, and is arranged in elongated top 22 together with movable axis.Movable axis 4 is connected to base 5 separably, and base 5 is connected to the bottom on elongated top 22.In addition, the central authorities of base 5 are formed with through hole 51, as shown in Figure 2.
When topple in bottle fluid time, movable axis 4 is separation with base 5 under the pressure of fluid, make fluid flow in elongated top 22 and from fluid egress point 23 and flow out via base plate through holes 51 along the direction shown in arrow in Fig. 1, and when bottle is vertically placed, movable axis 4 is reflected back on base 5 and with base 5 and is formed coupling sealing by elastic body 3, thereby prevents that the fluid holding in bottle from flowing out.Therefore, bottle cap of the present utility model has automatic airtight function.
Next, with reference to Fig. 2 and Fig. 3, illustrate in greater detail according to the structure of automatic airtight bottle cap of the present utility model.
Particularly, in an example of the present utility model, elongated top 22 comprises the tapered portion 221 that narrows gradually towards fluid egress point 23 and the cylindrical bottom portion 222 with bottleneck connecting portion 21 adjacency.Cylindrical bottom portion 222 is formed with negative thread.Base 5 has cylinder form, and is formed with outside thread.The outside thread of base 5 engages with the negative thread of cylindrical bottom portion 222, and the other end of base 5 is resisted against on bottleneck, thereby the movable axis 4 of the flexible body 3 of cover is remained in elongated top.According to an example, bottleneck connecting portion 21 is hollow cylinder, and this cylinder forms has negative thread to be connected with the outside thread of bottleneck, thereby automatic airtight bottle cap is connected on bottle.Described cylindrical finish connecting portion is only as example at this, and the connection mode of bottle cap and bottleneck is not limited to this, can adopt any connection mode known in the art.
The outside face on elongated top 22 preferably can have protruding card article 223.The open end of over cap 1 has draw-in groove; projection card article 223 is stuck in the draw-in groove of over cap 1 so that over cap is connected on seal cover cap; and can prevent that over cap from coming off from seal cover cap, thereby protection seal cover cap can be not contaminated, therefore can keep the fluid that obtains clean hygiene for use.
For example, elastic body 3 can be spring, and the material that can directly be contacted with food by corrosion-resistant steel, polyethylene etc. is made.Elastic strength to be can smooth and easyly pour out a bottle inner fluid, and base make the groove of movable axis and the coupling of the protrusion of base is sealed into good can rebound movable axis again after fluid is finished down.Except elastic body, the miscellaneous part of bottle cap of the present utility model all adopts the injection mo(u)lding respectively of food grade plastic material, for example, can adopt polyethylene (PE), polypropylene (PP) and similar material, then assembles the bottle cap of automatic airtight.
Although exemplary embodiments of the present utility model is illustrated, but obviously it will be appreciated by those skilled in the art that, in the situation that not deviating from spirit of the present utility model and principle, can change, its scope claims with and equivalent in limit.
