Description

A kind of rotatory sealing bottle cap

Technical field

The utility model is related to drink packing device, and in particular to a kind of seal bottle cap.

Background technology

As living standard is improved, beverage products classification is numerous and diverse, has what direct bottle cap was tightened with body, has suction pipe to poke guarantor Cuticula, have what lid was directly fastened with body.In general, the allotment of drink has been completed before dispatching from the factory, and traditional bottle cap is only Simple sealing function can be played.Either screw capping formula, or packed, also or diaphragm type sealing, once open, easily occur Oxidation, especially when some dispensings are unstable, perishable, easily lose activity, the preservation such as to easily deactivated saccharomycete. ZL201320406743.X proposes a kind of combined bottle cap, and upper lid is dismantled with lower cover and fixed, raw material be stored in the inwall of lid with In the confined space of closure composition, pass through coming off for closure so that raw material is slipped in bottle.But coming off for diaphragm seal lid makes Dispensing is obtained once to discharge, can not regulate and control.

The content of the invention

The purpose of this utility model is to provide a kind of rotatory sealing bottle cap, to solve the above problems.

The utility model provides a kind of rotatory sealing bottle cap, including upper lid, lower cover, and the upper lid is with internal thread wall, the One ring wall, center column；The lower cover has an external screw thread wall, and lower cover bottom has an aperture combination portion, and aperture combination portion is to body Convergence extension；The internal thread wall is connected with the external screw thread wall；The center column bottom is connected with the aperture combination portion, And the center column bottom convergence direction is consistent with aperture combination portion convergence direction.

Further, the center column bottom end is acute angle.

Further, the center column is fixedly connected with the upper lid dismounting.

Further, the center column bottom forms gap passage with the aperture combination portion.

Further, there is internal thread wall in aperture combination portion lower lumen.

The utility model has advantages below compared with prior art：

1. on cover and be not only threadedly coupled with lower cover, the center column of upper lid is also connected with lower cover plug so that with reference to tighter It is close；

2. the tightness degree of the combination of center column and lower cover, and center column bottom form gap with aperture combination portion and led to Road can control the rate of release and burst size of dispensing, reach the protection to active mushroom activity, for example：Budding fungus is lived Property agent preservation with prevent its go bad；

3. the bottom end of center column is acute angle.

In summary, the bottle cap that the utility model is provided being capable of gradation, the release of component regulation and control dispensing, simple in construction, suppression Strongly fragrant large-scale production, it is with low cost.

Embodiment

As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, the utility model provides a kind of rotatory sealing bottle cap, including upper lid 1, under Lid 2, the upper lid has internal thread wall, the first ring wall 5, center column 3；The lower cover has external screw thread wall, lower cover bottom tool There is aperture combination portion 4, aperture combination portion restrains to body to be extended；The internal thread wall is connected with the external screw thread wall；In described The bottom of stem body 3 is connected with the aperture combination portion 3, and center column bottom convergence direction and the aperture combination portion Restrain direction consistent.Wherein, the center column is fixedly connected with the upper lid dismounting, or center column and the upper lid one It is body formed.

It can be seen that the center column bottom end is acute angle from Fig. 2,4,5, and as can be seen from Figure 4 newel Body bottom end is that acute angle interior angle more convergent than aperture combination portion is big.

It can be seen that the center column bottom forms gap passage with the aperture combination portion from Fig. 2,4,5, and There is internal thread wall in aperture combination portion lower lumen.

Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for this For the technical staff in field, the utility model can have various knowable changes and change.It is all in principle of the present utility model Within spirit, made any equivalent substitution, modification, improvement etc., should be included in protection domain of the present utility model it It is interior.
