Embodiment

Presently filed embodiment is described in detail below in conjunction with drawings and Examples, and thereby how the application is applied Technological means can fully understand and implement according to this to solve technical problem and reach the implementation process of technical effect.

It should also be noted that, term " comprising ", "comprising" or its any other variant are intended to nonexcludability Comprising so that process, method, commodity or system including a series of elements not only include those key elements, but also wrapping Include the other key elements being not expressly set out, or also include for this process, method, commodity or system intrinsic want Element.In the absence of more restrictions, the key element limited by sentence "including a ...", it is not excluded that wanted including described Other identical element also be present in the process of element, method, commodity or system.

Fig. 1 to Fig. 7 is referred to, double Pop-top seal caps of the present utility model include rubber head 10, inner cap 20 and enclosing cover 30.Rubber head 10 have first end 11, the second end 12 for connecting first end 11, the through hole through first end 11 and the second end 12 14 and the seal 13 of the side wall of through hole 14 is connected, the inner peripheral surface of first end 11 sets rotating gravure 111, in rotating gravure 111 With internal thread, the outer peripheral face of the second end 12 has several projections 121, and seal 13 is located at first end 11 and the second end Between 12, and the connection between first end 11 and the second end 12 is blocked, and portion 131 is pulled open with first.Inner cap 20 includes close Shrouding 21 and the rotation wall 22 for being located on sealing plate 21, the outer surface of rotation wall 22 have the external screw thread relative with internal thread, when When inner cap 20 is arranged at rubber head 10, rotation wall 22 is bolted in rotating gravure 111, and sealing plate 21 is located at the top of seal 13.Outside Lid 30 includes hollow out top surface 31 and is located on the socket wall 32 of hollow out top surface 31, and hollow out top surface 31 has second to pull open portion 311, outside The socket wall 32 of lid 30 is socketed on the outer peripheral face of the first end 11 of rubber head 10, and hollow out top surface 31 is arranged at the top of rubber head 10, Second pulls open the top that portion 311 is located at inner cap 20.In one embodiment of the present utility model, first pulls open portion 131 and second It is draw ring to pull open portion 311, or well known in the art other pull open part, do not add to repeat herein.

Several projections 121 of rubber head 10 are uniformly distributed in the outer peripheral face of the second end 12.Several projections 121 are respectively back taper Shape, and protruded from the outer peripheral face of the second end 12.When rubber head 10 is arranged at the seal of part to be sealed, because of the material of rubber head 10 Flexible, during the insertion seal of the second end 12 with several projections 121, the second end 12 produces because of extruding Deformation.After the second end 12 enters seal, the second end 12 through deformation then resiles, now, several projections 121 The surface being just locked to around seal, so that double Pop-top seal caps seal part to be sealed, and it is not easy double Pop-top seal cap lids Depart from from part to be sealed.

It is described below in detail how double Pop-top seal caps of the present utility model use.In order to open enclosing cover 30, by Two pull open portion 311 pulls open upwards, and hollow out top surface 31 and socket wall 32 are accordingly acted on by external force, because rubber head 10 is elastic material Material, its external force transmitted by enclosing cover 30 act on deformation, the thus socket between socket wall 32 and the first end 11 of rubber head 10 State is broken, and enclosing cover 30 comes off from rubber head 10.Now, inner cap 20 is exposed, because inner cap 20 is bolted in rubber head 10 First end 11, now need to rotate inner cap 20 and open.After inner cap 20 screws out from rubber head 10, the seal of rubber head 10 13 are exposed, and seal 13 pulls open portion 131 by pulling open first upwards, and seal 13 comes off from rubber head 10.It should be noted Be, seal 13 can easily coming off from rubber head 10, but extraordinary sealing property can be kept.It is understood that First, which pulls open portion 131 and second, pulls open after portion 311 pulls off and can not recover, and serves anti-fake effect.Inner cap 20 can revolve again It is screwed in rubber head 10 and forms sealing, so as to recycles.

The external diameter of the first end 11 of the rubber head 10 of double Pop-top seal caps of present embodiment is more than its second end 12 External diameter, first end 11 protrude relative to the second end 12.The end of the socket wall 32 of right enclosing cover 30 can have fastening end 321, Socket wall 32 can be sticked in the first end 11 for the rubber head 10 protruded relative to the second end 12 of rubber head 10 by fastening end 321, So as to stablize its socket state.

From the foregoing, double Pop-top seal caps of the present utility model work as enclosing cover directly in being provided with seal 13 in rubber head 10 30 and inner cap 20 when removing, the seal 13 in rubber head 10 still suffers from, and has the function that false proof.Inner cap 20 passes through screw thread insertion side Formula connects with the resistance of rubber head 10, effectively prevents inner cap 20 from departing from rubber head 10 because different from the material of rubber head 10.This right implementation is new Double Pop-top seal caps seal rubber head 10 simultaneously using seal 13 and inner cap 20, reach double-layer seal and improve double Pop-top seal caps Sealing.Double Pop-top seal caps of the present utility model it is simple to operate, improve operating efficiency, reduce production cost.

Some preferred embodiments of the application have shown and described in described above, but as previously described, it should be understood that the application Be not limited to form disclosed herein, be not to be taken as the exclusion to other embodiment, and available for various other combinations, Modification and environment, and above-mentioned teaching or the technology or knowledge of association area can be passed through in the scope of the invention is set forth herein It is modified., then all should be in this Shen and the change and change that those skilled in the art are carried out do not depart from spirit and scope Please be in the protection domain of appended claims.
