Abstract

The utility model relates to a combined bottle cap, which comprises an inner shell and an outer shell. The inner shell is provided with a center sunken area, a sealing plug tightly matching with the center sunken area is arranged insides the outer shell, and an outer shell air passage is disposed in an area of the surface at the upper end of the outer shell which is not coincident with the sealing plug. Relative movement of the inner shell and the outer shell can be controlled through a sliding groove, thereby controlling isolation or communication between the interior and the exterior of a bottle, avoiding taking down the bottle cap from the neck of the bottle, not only bringing convenience for using, but also reducing risk of losing the bottle cap. As a dustproof shell which is in threaded connection with the outside of the outer shell is arranged outside the outer shell, fingers or teeth of users can not contact with a drinking portion, thereby leading the users to drink in a relative sanitary way.

Above-mentioned technical purpose of the present utility model is achieved through the following technical solutions: a kind of compound type bottle cap, comprise inner casing that links to each other with bottleneck and the shell that links to each other with the inner casing outside thread, described inner casing is provided with the concavity district, be provided with the airtight plug that closely matches with the concavity district in the shell, the zone that shell upper end face and airtight plug do not coincide is provided with the shell air by-pass passage.

As preferably, described concavity district comprises inner casing projection and the inner casing air by-pass passage that exceeds the inner casing upper end face, and the shell upper end face is provided with the ducted body that closely matches with the inner casing projection.

As preferably, the outer wall of described inner casing and inner casing upper surface are respectively arranged with the inner casing card article and the inner casing fixture block that can limit the extreme higher position that lifting body rises.

Further preferred, the inwall of shell and the lower surface of shell are respectively equipped with shell card article and the shell fixture block that matches with inner casing card article and inner casing fixture block.

As preferably, described inner casing outer wall thread is a sliding tray, and the inwall of shell is provided with the slide protrusion that matches with sliding tray.

Further preferred, two terminal line of centerss of described sliding tray all are parallel to the inner casing upper end face.

As preferably, described inner casing outer wall is provided with the convenient inner casing groove that slide protrusion is pressed into sliding tray.

As preferably, on the outer shell outer wall at described slide protrusion place thin-wall regions is arranged.

As preferably, described shell is provided with outward and shell outside thread bonded assembly dustproof shell.

Further preferred, the upper end face of described dustproof shell is provided with the dustproof shell duct that the ducted body with shell matches.

Practical beneficial effect of the present utility model is:

1, the compound type bottle cap that comprises inner casing and shell that the utility model provides, its inner casing links to each other by the sliding tray that two terminal line of centerss all are parallel to the inner casing upper end face with shell, inner casing is provided with the concavity district, be provided with the airtight plug that closely matches with the concavity district in the shell, the zone that shell upper end face and airtight plug do not coincide is provided with the shell air by-pass passage, can control the relative motion of inner casing shell by sliding tray, thereby inside and outside isolation or the connection of control bottle, bottle cap need not be taken off from bottleneck, not only easy to use, and reduced the risk that bottle cap is lost;

2, the compound type bottle cap that provides of the utility model owing to have and shell outside thread bonded assembly dustproof shell at the shell peripheral hardware, so refer to or tooth can not contact and drinks the position, makes and drinks relative health.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

A kind of compound type bottle cap, comprise inner casing 1 that links to each other with bottleneck and the shell 2 that links to each other with inner casing 1 outside thread, inner casing 1 is provided with concavity district 4, be provided with the airtight plug 5 that closely matches with concavity district 4 in the shell 2, the zone that shell 2 upper end faces and airtight plug 5 do not coincide is provided with shell air by-pass passage 6, and this shell air by-pass passage 6 is circulation passages of bottle inner air and outer air or liquid.Concavity district 4 comprises inner casing projection 7 and the inner casing air by-pass passage 8 that exceeds inner casing 1 upper end face, and shell 2 upper end faces are provided with the ducted body 9 that closely matches with inner casing projection 7.The outer wall of inner casing 1 and inner casing 1 upper surface are respectively arranged with the inner casing card article 10 and the inner casing fixture block 11 of the extreme higher position that can limit the lifting body rising, and the lower surface of the inwall of shell 2 and shell 2 is respectively equipped with shell card article 12 and the shell fixture block 13 that matches with inner casing card article 10 and inner casing fixture block 11.Inner casing 1 outer wall thread is a sliding tray 14, and the inwall of shell 2 is provided with the slide protrusion 15 that matches with sliding

tray

14, and 14 two terminal line of centerss of sliding tray all are parallel to inner casing 1 upper end face.Inner casing 1 outer wall is provided with the convenient inner casing groove 16 that slide protrusion 15 is pressed into sliding tray 14.On shell 2 outer walls at slide protrusion 15 places thin-wall regions 17 is arranged.Shell 2 is outer to be provided with and shell 2 outside thread bonded assembly dustproof shell 3, and the upper end face of dustproof shell 3 is provided with the dustproof shell duct 18 that the ducted body 9 with shell 2 matches.By the relative motion of sliding tray 14 and slide protrusion 15 control inner casings 1 and shell 2, thereby airtight plug 5 is combined with concavity district 4 and separate; When airtight plug 5 combines with concavity district 4, isolate mutually with bottle is outer in the bottle, when airtight plug 5 separated with concavity district 4, liquid that bottle is inside and outside or air can be by shell air by-pass passage 6 circulations of shell 2; And two terminal line of centerss of sliding tray 14 all are parallel to inner casing 1 upper end face, can make to outward winding or the slide protrusion when closing bottle cap 15 keeps static relatively; Owing to shell 2 outside, be provided with and shell 2 outside thread bonded assembly dustproof shell 3,, feasiblely drink relative health so refer to or tooth can not contact and drinks the position; Inner casing projection 7, ducted body 9 and dustproof shell duct 18 are the one that cooperatively interact, and strengthen the isolation features of this bottle cap; So dustproof shell 3 is very beautiful because of what have only a dustproof shell duct 18 to do, can play effect attractive in appearance; Dustproof shell duct 18 also is to serve the purpose that does not need to take off bottle cap when bottle interior object is contacted with the bottle outer air.

The above only is a preferred embodiment of the present utility model, be not so promptly limit claim of the present utility model, the equivalent structure transformation that every utilization the utility model specification sheets and accompanying drawing content are done, directly or indirectly be used in other relevant technical fields, all in like manner be included in the claim of the present utility model.
