Abstract

The utility model relates to a novel double-layer bottle cap which comprises an inner cap and an outer cap. Internal threads which are connected with a bottle opening are arranged on the inner side of the inner cap, the outer cap rotatably sleeves the inner cap, a plurality of holes are formed in the inner cap, the distance between each two adjacent holes in the same circumference is larger than the lengths of the holes, holes are formed in the outer cap, the sizes of the holes in the outer cap are identical to the sizes of the holes in the inner cap, position distribution of the holes in the outer cap is identical to position distribution of the holes in the inner cap, the holes in the outer cap can completely coincide with the holes in the inner cap, eight axial limiting protrusions which are used for constraining the rotation amplitude of the outer cap are respectively uniformly arranged on the outer wall of the inner cap and the inner wall of the outer cap, two wedge-shaped clamp rings which are used for clamping the outer cap on the inner cap are respectively arranged on the outer wall of the inner cap and the inner wall of the outer cap, and an elastic friction layer is arranged on a cap surface of the inner cap and is in close contact with the outer cap. The novel double-layer bottle cap has the advantages that the outer cap and the inner cap are individually manufactured, then the outer cap can press the inner cap by the aid of slight force, and accordingly the novel double-layer bottle cap is simple in manufacture; the novel double-layer bottle cap is additionally provided with the friction layer, and accordingly the inner cap and the outer cap of the double-layer bottle cap can be effectively prevented from moving relatively.

Description

New double-deck bottle lid

Technical field

The utility model relates to a kind of bottle cap, relates in particular to a kind of New double-deck bottle lid.

Background technology

Bottle with cover has brought very large convenience to the people's life, people are in the time using bottle dress seasonings or other pulverous materials, several apertures are often set as required on the bottle cap of bottle, by aperture, powdered substance is poured out to bottle when needed, determine the size of aperture or the quantity of aperture according to the amount of frequent needs, but people in use can pour out according to different needs the material of different amounts, if what aperture was opened is too small or too small, in the time need to pouring out relatively large material, just need for a long time, if it is excessive that aperture is opened, can in not needing too many material, pour out excessive material, cause the waste of material, and be not easy to control, the bottle cap of the discharge adjustable hole size of existing a kind of bilayer, but very flexible between the inner cap of this bottle cap and enclosing cover, easily there is relative motion, thereby the aperture size having regulated is changed, the production procedure of this bottle cap is cumbersome in addition, and very complicated.

Utility model content

In view of this, the purpose of this utility model is to provide a kind of New double-deck bottle lid, thereby solves the problem that prior art exists.

The utility model is to realize like this, a kind of New double-deck bottle lid, comprise inner cap and enclosing cover, the inner side of described inner cap is provided with the negative thread being connected with bottleneck, described enclosing cover is enclosed within outside inner cap rotationally, inside cover uniform some holes that are provided with, distance on same circumference between adjacent hole is greater than the length in hole, cover be outward provided with identical with the interior hole size covering, identical and the hole that can overlap completely of position distribution, uniform axial limiting projections that are provided with 4 restriction enclosing cover rotation amplitudes respectively on the outer wall of inner cap and the inwall of enclosing cover, on the outer wall of inner cap and the inwall of enclosing cover, be provided with the collar of a circle for covering in enclosing cover is stuck in, collar is wedge shape, on the capping of inner cap, be provided with one deck elastic-friction layer, this elastic-friction layer and enclosing cover close contact.

Further, described elastic-friction layer is rubber layer.

Further, described inner cap and the hole that covers setting are outward curved waist hole, and waist hole is at inner cap and cover outward along the circle distribution of two different radiis, distribute 2 on inner periphery, distribute 4 on excircle.

The advantage of a kind of New double-deck bottle lid that the utility model provides is: compared with prior art, the utility model can be produced separately enclosing cover and inner cap in the time producing, then in a little firmly enclosing cover can being pressed in, cover, produce comparatively simple, simultaneously the utility model is by increasing one deck friction layer, can actv. prevents the relative motion of inner cap and the enclosing cover of Double layer bottle cap.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

See also Fig. 1, Fig. 2, Fig. 3 and Fig. 4, wherein, Fig. 1 is the birds-eye view of New double-deck bottle lid of the present utility model, Fig. 2 is the upward view of New double-deck bottle lid of the present utility model, Fig. 3 be New double-deck bottle lid of the present utility model along diametric cutaway view, Fig. 4 is the A place enlarged drawing in Fig. 3.

As shown in FIG., a kind of New double-deck bottle lid of the present utility model, comprise inner cap 2 and enclosing cover 1, the inner side of described inner cap 2 is provided with the negative thread 26 being connected with bottleneck, described enclosing cover 1 is enclosed within outside inner cap 2 rotationally, the uniform curved waist hole 23 that is provided with on inner cap 2, waist hole 23 on inner cap 2 along the circle distribution of two different radiis, on inner periphery, distribute 2, on excircle, distribute 4, distance on same circumference between adjacent two waist holes 23 is greater than the length in waist hole 23, on enclosing cover 1, be provided with identical with waist hole 23 sizes on inner cap 2, identical and the waist hole 13 that can overlap completely of position distribution, uniform axial limiting projections 24 that are provided with 4 restriction enclosing cover 1 rotation amplitudes respectively on the inwall of the outer wall of inner cap 2 and enclosing cover 1, 14, on the inwall of the outer wall of inner cap 2 and enclosing cover 1, be provided with a circle for enclosing cover 1 being stuck in to the collar 25 on inner cap 2, 26, collar 25, 26 are wedge shape, on the capping of inner cap 2, be provided with one deck elastic-friction layer 7, this elastic-friction layer 7 and enclosing cover 1 close contact, this elastic-friction layer 7 is made for elastomeric material.

In sum, the advantage of a kind of New double-deck bottle lid that the utility model provides is: compared with prior art, the utility model can be produced separately enclosing cover and inner cap in the time producing, then in a little firmly enclosing cover can being pressed in, cover, produce comparatively simple, simultaneously the utility model is by increasing one deck friction layer, can actv. prevents the relative motion of inner cap and the enclosing cover of Double layer bottle cap.
