Abstract

A moisture-proof drying bottle cover is disclosed whose top cover inner side is provided with a double-layer ring column wall, the area enclosed by two inner layers of ring column walls (1,3) is used to place desiccant (5), the opening of the bottle cap is provided with a breathable enclosing cover (7), the outer diameter of the outer layer of the ring column wall (1) is the same with that of the bottle mouth (8), when used, the outer layer of the ring column wall (1) is inserted into the bottle mouth (8), the utility model is characterized in that an elastic stretching wrench ring (2) fixed in the inner side of the top cover (4) is arranged between the two layers of ring shaped walls (1,3); preferably, the outer edge of the top cover (4) is wholly injected with a ring shaped theft-proof ring (6), and a multiple points connection (61) is arranged between the theft-proof ring (6) and the top cover (4), a plurality of locking plates (62) inclined upwards are distributed on the inner wall of the theft-proof ring along the periphery. Compared to the prior art, the utility model can be injected wholly, so the utility model is high in production efficiency, and at the same time is provided with a reliable theft-proof performance.

Description

The dry bottle cap of a kind of protection against the tide

The utility model relates to a kind of bottle cap, especially for the moistureproof dry bottle cap of medical tablet bottle etc.

Existing being used in the moistureproof dry bottle of needs such as medical tablet, need the extra desiccant of placing, simultaneously for preventing that tablet rocks in the transportation in bottle, colliding, also needing to put into things such as spitball or cotton at bottleneck is fixed, therefore, when taking tablet, all need earlier desiccant and fixture to be taken out at every turn, again they are put back in the bottle after having got tablet, use inconvenience; Therefore, for asking convenient, also there is the user often when the first time, just desiccant, fixture to be thrown away, thereby influenced the preservation and effect of tablet.For this reason, the patent No. is that 98242397.7 " retractility bottle stopper " provides a kind of bottle cap that tablet effect in the dry and fixing bottle can be provided simultaneously, it comprises enclosing cover, inner cap and retractility spring, and described enclosing cover center position is equipped with a hollow inner core, is provided with an annular groove all around; The torsion spring lower end links to each other with the inner cap bottom, and the upper end is sleeved on the inner core, and inner cap embeds in the enclosing cover groove all around.Because it is made of enclosing cover, torsion spring, inner cap three parts, and its structures shape this three must separately make to refill and join one, and can not be integrally manufactured, therefore make troubles in actual applications, it is also low to make efficient.

The utility model purpose just is to provide at above-mentioned prior art present situation a kind of structure more simple, moistureproof dry bottle cap that can be integrally manufactured.

Another purpose of the present utility model is to provide a kind of moistureproof dry bottle cap with theft-prevention structure.

The purpose of this utility model is achieved in that the top cover inboard of moistureproof dry bottle cap is provided with two layers of annulated column wall, wherein the inner layer ring post jamb space of being enclosed promptly is used for placing desiccant, its peristome is provided with a ventilative capping, the external diameter of outer layer ring post jamb is then consistent with bottleneck diameter, insert in the bottleneck during use, it is characterized in that, between described two layers of annular wall, be provided with the elastic telescopic torsion circle that the top is fixed on the top cover inboard.

Described annulated column wall and elastic telescopic torsion circle all can with the top cover integrated through injection molding; Described inner layer ring post jamb can be provided with a step at opening part, and the bead portion under the step then has the diminishing closing in structure of internal diameter, and described ventilative capping promptly is limited in therebetween; But described top cover outer side also one is injected with a ring-type pilfer band, be connected for the multiple spot of easily breaking between pilfer band and the top cover, its inwall is along circumferentially being distributed with several only cramps obliquely, and when the bottleneck that turns edge outside having inserted, these ended cramp and just in time withstand the bottleneck outer.

Compared with prior art, the utility model is simple in structure, except that ventilative capping, all but one is injection molded, therefore make the efficient height, and the design of ring-type pilfer band makes bottle cap the ring-type pilfer band must be separated with bottle cap devastatingly before unlatching, thereby the failure-free theftproof performance is provided.

Description of drawings.

Fig. 1 is the structure cross-sectional schematic of the utility model embodiment.

Fig. 2 is the schematic perspective view of the utility model embodiment.

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, the moistureproof dry bottle cap of present embodiment is an integral molded plastic spare, its top cover 4 inboards are provided with two layers of annulated column wall 1,3, wherein inner layer ring post jamb 3 space of being enclosed promptly is used for placing desiccant 5, its opening part can be provided with a step, bead portion under the step has the diminishing closing in structure of internal diameter, and a ventilative capping 7 promptly is limited in therebetween; The external diameter of outer layer ring post jamb 1 is then consistent with bottleneck 8 diameters, inserts during use in the bottleneck;

Be provided with the elastic telescopic torsion circle 2 with top cover 4 inboard integrated through injection molding between described two layers of ring-type post jamb 1,3, during use, its annular free end 21 props up a bottle interior uppermost tablet (not shown);

Described top cover 4 outer sides also one are injected with a ring-type pilfer band 6, be connected 61 for the multiple spot of easily breaking between pilfer band 6 and the top cover 4, its inwall is along circumferentially being distributed with a plurality of only cramps 62 obliquely, when 81 the bottleneck 8 that turns edge outside having inserts, these end cramp 62 and just in time withstand bottleneck outer 81, and like this when bottle cap is extracted for the first time, pilfer band 6 is connected 61 with multiple spot between the top cover 4 and will be broken, end simultaneously cramp 62 also drawn bad, thereby play antitheft effect.
