Description

A kind of bottle cap sealing structure

Technical field

The utility model relates to a kind of bottle cap sealing structure.

Background technology

The bottle cap sealing of this structure such as mineral water, beverage that current market is sold is relatively simple for structure, there will be bottle cap oneself phenomenon that is loosening or that throw off and causes the article held leak or spill, especially very outstanding in this problem of occasion of motion; And when we outward winding bottle cap again, the liquid in bottle can stick on bottle cap and be brought out, stick on hand or clothes etc. local and unhygienic.

Utility model content

The technical problems to be solved in the utility model is: provide a kind of bottle cap sealing structure, effectively prevents the article such as the liquid in bottle from sticking in the place such as on hand cause unhygienic when bottle cap is opened.

For solving the problems of the technologies described above, the utility model bottle cap sealing structure comprises and arranges threaded bottleneck and be threaded connection the bottle cap on bottleneck, be provided with interior bottle cap between described bottle cap and bottleneck, described interior bottle cap is movably connected in the upper of bottleneck, and this interior bottle cap is horizontally arranged with extension plate; The periphery of described bottle cap is horizontally arranged with the groove of annular protrusion that can hold extension plate and embed, and the periphery of described bottle cap has can adapt to extension plate and enter breach in groove.

Loosen to prevent bottle cap oneself or throw off, be provided with keep plate in described groove, described keep plate is connected with groove by springing.

In order to cost-saving, described springing is made up of the spring of at least one.

In order to reach better sealing effectiveness, described interior bottle cap is conical plug.

The beneficial effects of the utility model are: the utility model by arranging interior bottle cap between bottle cap and bottleneck, the Contact bottle cap of the article such as the liquid in bottle can be prevented, thus effectively prevent article and stick on bottle cap, solve article when outwarding winding bottle cap and can stick in and cause antihygienic problem on hand; The utility model by being provided with keep plate in groove, keep plate is connected with groove by springing, after screwing bottle cap, springing compressed thus drive keep plate to contact completely with interior bottle cap and to the downward pressure of interior bottle cap by its tightly be pressed in the leakage that bottleneck effectively prevent the article such as liquid; Simultaneously can prevent from bottle cap oneself from fluffing under the effect of the application force of springing and the friction force of keep plate and interior bottle cap to move or throw off.Again, even if bottle cap occurs to loosen due to the reason oneself such as vibrations, because the extension plate of interior bottle cap is also in groove, can prevent from coming off completely the problem causing article in bottle to leak completely because of bottle cap.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

As shown in Figure 1, the utility model bottle cap sealing structure comprises bottleneck 1 and bottle cap 3, bottleneck 1 is provided with screw thread 2.As shown in Figure 1, bottle cap 3 and bottleneck 1 are screwed by screw thread 2 and link together, and the upper end of bottleneck 1 utilizes articulate to be connected with interior bottle cap 4, and interior bottle cap 4 horizontal cross is provided with extension plate 5.As shown in Figure 1, the periphery of bottle cap 3 being horizontally arranged with the groove 6 that can hold the annular protrusion that extension plate 5 embeds, this makes it possible to ensure that bottle cap 3 rotates when not interfering with each other with extension plate 5.As shown in Figure 2, in order to extension plate 5 can be allowed can to enter into smoothly in groove 6, the periphery of described bottle cap 3 is provided with and can adapts to extension plate 5 by entering the breach 7 of groove 6.

Principle of work of the present utility model: first bottle cap 3 is placed on bottleneck 1, extension plate 5 is made to enter in groove 6 by breach 7, then rotary bottle cover 3 utilize screw thread 2 to make it screw this time slot 6 can to the downward pressure of extension plate 5 one, by interior bottle cap 4 being pressed on bottleneck 1 tightly.Utilize this structure to be separated with bottle cap 3 actv. by the article such as the liquid in bottle by actv., thus avoid because of the article such as liquid stick in bottle cap 3 causes open bottle cover 3 time by the problem of hand contamination, convenient, healthy.Giving the downward pressure of extension plate 5 can effectively prevent article in bottle from the problem of leaking occurring simultaneously, again can prevent bottle cap 3 and bottleneck 1 from throwing off completely by extension plate 5 and the mutual restriction of groove 6.

Loosen to prevent bottle cap 3 oneself or throw off, the basis of said structure is improved further.As shown in Figure 1, be provided with keep plate 8 in groove 6, described keep plate 8 is connected with groove 6 by springing 9.In order to save production cost, springing 9 is here made up of (it should be noted that those skilled in the art can according to the conversion of this flexible structure here, such as springing 9 can be set to elastic pressuring plate) the spring of at least one.This structure can utilize friction force between keep plate 8 and interior bottle cap 4 and springing 9 to the application force of bottle cap 3, effectively prevent bottle cap 3 because vibrations or the problem oneself loosening or throw off that rubs.In order to reach better sealing effectiveness further, described interior bottle cap 4 is the stopper of taper, and simply, convenient, sealing effectiveness is better.

It should be noted that the present embodiment is most preferred embodiment of the present utility model, be not restriction the utility model being made to other form, any those skilled in the art of belonging to may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent implementations of equivalent variations.But every do not depart from the prerequisite of the utility model know-why under, any simple modification, equivalent variations and the remodeling done above embodiment according to technical spirit of the present utility model, all should fall into the utility model scope of patent protection.
