Abstract

The utility model relates to a bottle cap, which comprises an outer cap and an inner cap, wherein the inner top of the outer cap is provided with a ratchet in the circumferential direction; the inner surface of the lower edge of an opening of the outer cap is also provided with a circle of convex rings; the outer top of the inner cap is provided with a ratchet pawl matched with the ratchet on the outer cap in the circumferential direction; the outer surface of the lower edge of an opening of the inner cap is also integrally provided with concave rings matched with the convex rings of the outer cap; because the inner cap is made of plastics with low hardness, the inner top of the inner cap is provided with a sealing ring in axial butt joint with a bottle opening; thus, a sealing strip in the existing bottle caps can be omitted. The utility model not only reduces the cost of the bottle cap, but also prevents problems because users loss the sealing strip carelessly.

Description

Bottle cap

Technical field

The utility model relates to a kind of bottle cap, particularly a kind of bottle cap of medicine special-purpose bottle.

Background technology

Medicine, particularly some has the medicine of certain danger to keep properly to human body, prevents that the preschool child from eating by mistake.For preventing that the preschool child from eating the incident generation of medicine by mistake, people reform on drug container, as Chinese utility model patent CN2388143Y, provide a kind of resistant closure.The inner cap of resistant closure and enclosing cover normal-running fit.Have a circle ring gear and at least more than one flexure strip on the enclosing cover inner top surface; The outer end face of inner cap has a circle to reach the supporting rib that cooperates with flexure strip with the identical and intermeshing ring gear of the enclosing cover inner top surface number of teeth.The driving surface of flexure strip is parallel to the driving surface of supporting rib; The height of supporting rib is lower than the height of ring gear; Flexure strip be not subjected to external force to do the time spent, and its vertex withstands on the outer end face of inner cap, and inside and outside lid ring gear is separated; Be threaded on the inner cap inwall.This scheme can prevent that the preschool child from opening by mistake, but following deficiency is arranged, most medicines have the requirement of sealing preservation, make moist or oxidation preventing, mostly existing bottle cap is at lid liner one seal strip, cover when tight it and be squeezed in the lid and realize sealing between top and bottleneck, this makes the cost of lid higher relatively, and seal strip also often has situation about coming off to take place.In addition, for the bigger bottle of lid mouthful diameter, when pressing unlatching, the easy run-off the straight of the relative inner cap of enclosing cover, at this moment, two teeth that cover not are whole engagements, cause the damage of engaging tooth, can not open when serious.

Summary of the invention

Main purpose of the present utility model provides a kind of bottle cap that has the low hermetically-sealed construction of cost;

Another purpose of the present utility model provides a kind ofly can also guarantee that when pushing the relative inner cap of enclosing cover is difficult for the bevelled bottle cap.

For achieving the above object, the designed bottle cap of the utility model comprises enclosing cover and inner cap, the top is circumferentially with ratchet in the enclosing cover, enclosing cover mouth lower edge inside face also is provided with all bulge loops, the outer top of inner cap is circumferentially with and covers the ratchet that ratchet cooperates outward, and inner cap mouth lower edge outside face also is integrally formed with the scrobicular ring that cooperates with the enclosing cover bulge loop.Make by the not high plastics of hardness in view of inner cap is many, the top is provided with the seal ring that axially docks with bottleneck in inner cap, can save the seal strip in the existing Bottle cap structure like this, not only reduce the cost of bottle cap, prevent that also the user from losing the problem of bringing because of using careless seal strip.

Conceive further bottle cap according to the utility model, also can in enclosing cover, push up and inner cap outside the top between an axial guide part is set, like this, when press-started, guide part can prevent the relative tilt between two hd top face, thereby the trouble that can effectively avoid ratchet or ratchet unbalance stress to bring.

Be described further below in conjunction with several embodiment and accompanying drawing thereof.

Embodiment

First embodiment:

Referring to Fig. 1, enclosing cover 1 can be around axially to rotating with inner cap 2, and inner cap 2 can also axially jump in enclosing cover 1, and this axially directed portion that jumps constitutes guide pillar 14 and guide hole 24 free-running fits by the guide hole 24 on guide pillar 14 on the top in the enclosing cover and the outer top of inner cap.The top also is made into integration the seal ring 22 of projection in inner cap 2.

Referring to Fig. 2, guide pillar 14 is located at the center on top in the enclosing cover 1, and the top is provided with six ratchets 12 one week in the enclosing cover, and every ratchet 12 has a steep face 121 and an inclined-plane 122.

Referring to Fig. 3, also be provided with all bulge loops 13 at enclosing cover Gai Kou lower edge inside face, be used for to inner cap axially jump spacing.

Referring to Fig. 4, inner cap 2 outer tops are circumferentially with the ratchet 21 that cooperates with ratchet 12 on the enclosing cover 1, and inner cap 2 Gai Kou lower edge outside faces also are provided with the scrobicular ring 23 that cooperates with enclosing cover bulge loop 13, the seal ring 22 on top in the inner cap 2, and the collar extension diameter of seal ring 22 is identical with bottleneck diameter.

Referring to Fig. 5, six ratchets 21 all have two upright faces that push away, and when one of them pushed away the steep face 121 of enclosing cover 1, bottle cap was tight with the bottleneck lid; Another pushes away face and then is used to push away inclined-plane 122 on the enclosing cover 1, when two lids are applied axial force relatively, opens bottle cap, when not applying axial force, takes place to relatively rotate between two lids, and bottle cap is not opened bottleneck.

Referring to Fig. 6, do not belong to bottleneck 3 of the present utility model and represent with long and two-short dash line in the drawings, in this example, the seal ring 22 on inner cap 2 inside faces is bulge loops of a closing in, the axial abutment surface of itself and bottleneck 3 is the lateral surface of this bulge loop when lid is tight.

Second embodiment:

Referring to Fig. 7, this example and not existing together of first embodiment are that seal ring 22 is a rectangle bulge loop substantially, with the contact surface of bottleneck 3 two road sword rings 222 are arranged.

The 3rd embodiment:

Referring to Fig. 8, these routine characteristics are that the contact surface of seal ring 22 and bottleneck 3 has three road sword rings 223.

The 4th embodiment:

Referring to Fig. 9, these routine characteristics are seal rings 22 has sword ring 224 with the contact surface of bottleneck 3.

The foregoing description is used for this is implemented the explanation of novel design, but the utility model design is only for the foregoing description, and design also can have multiple simple structural change according to the utility model.
