Abstract
The utility model relates to an improved invention of bottle stopper used for enclosing bottle mouth, which belongs to the packaging field, comprises a cover and a stopper, and is characterized in that the cover is made of rigid plastics while the stopper is made of foamed elastic plastic. An internal gear is arranged at the periphery of the inner wall of the cover, an external gear is arranged at the periphery of one end of the stopper, and the internal and the external gears are in interference fit mutually so as to form the linkage connection of the cover and the stopper. In order to enhance the connection intensity of the cover and the stopper, firstly, the rigid plastic is molded to form the cover in an injected manner, then the foamed elastic plastic is injected to the inner cavity of the cover to form the stopper, therefore the mutual interference fit of the internal and the external gears can ensure the circumferential mutual rotation of the cover and the stopper, and the expansion friction force of the foamed elastic plastic ensures the axial mutual movement of the cover and the stopper.
Description
Technical field
The related a kind of bottle stopper of the utility model belongs to packaging field.
Background technology
Bottle stopper uses very extensive.Usually, T-shaped bottle stopper (or being T shape bottle stopper) is made up of closure outer shell and stopper two parts, and is that two kinds of different materials are made respectively.Adopt adhesion agent that closure outer shell and stopper are bonded as one then.As time goes on the variation of environment, some adhesion agent can wear out, and bonding firmness will reduce.When extracting bottle stopper, closure outer shell just might be separated with stopper.The stopper material of quite a few is to use granulated cork to add that adhesion agent compacting forms, and back and forth during plug, stopper can fall chip, fragmentation, cracking to this material at bottleneck; In the environment of humidity, may go mouldy.
Summary of the invention
In view of the deficiency that background technology exists, the technical problems to be solved in the utility model provides a kind of closure outer shell and stopper is twice injection moulding bonded assembly bottle stopper.Back and forth during plug, closure outer shell can not produce with stopper separates at bottleneck; Stopper can not fall chip, fragmentation, cracking; In the environment of humidity, can not go mouldy; And firm bottle stopper that can repeated use.
For this reason, the utility model adopts following technical scheme to realize: a kind of bottle stopper, comprise closure outer shell and stopper, and it is characterized in that described closure outer shell is a hard plastics; Described stopper is the foaming elastic plastic material.
The inwall circumference of described closure outer shell is provided with internal tooth, and an end circumference of described stopper is provided with external tooth, the connection that is meshing with each other of interior external gear.
The inwall circumference internal tooth of described lid is provided with 2 teeth at least, and the number of teeth of an end circumference external tooth of described stopper is corresponding with internal tooth.
The inwall circumference of described closure outer shell is provided with inner gear; One end circumference of described stopper is provided with external gear; The mutual close fit of interior external gear has constituted being connected of closure outer shell and stopper.In order to increase closure outer shell and stopper bonded assembly intensity, at first use rigid plastic material injection mo(u)lding closure outer shell, be injected into the inner chamber of closure outer shell then with the foaming elastic plastic material, the moulding stopper.The mutual close fit of interior external gear has guaranteed that closure outer shell and the circumferential of stopper captive joint; The expansion friction force of foaming elastic plastic material has guaranteed that the axial restraint of closure outer shell and stopper is connected.

Fig. 3 is the stopper front view in the utility model.
Fig. 4 is the stopper birds-eye view in the utility model.
Fig. 5 is the structural front view of the utility model embodiment.
Fig. 6 is the structure birds-eye view of the utility model embodiment.
Fig. 7 is the structure cutaway view of the utility model embodiment.
The specific embodiment:
To as can be known shown in Figure 7, a kind of bottle stopper of the utility model includes closure outer shell 1 and stopper 2 as Fig. 1.Described closure outer shell 1 is a hard plastics; Described stopper 2 is the foaming elastic plastic material.The inwall circumference of described closure outer shell 1 is provided with inner gear 11; One end circumference of described stopper 2 is provided with external gear 21; Interior external gear (11 and 21) close fit has mutually constituted being connected of closure outer shell 1 and stopper 2, and both closure outer shell 1 and stopper 2 captiveed joint.
In order to increase closure outer shell 1 and stopper 2 bonded assembly intensity, at first use hard plastics injection mo(u)lding closure outer shell 1, be injected into the inner chamber of closure outer shell 1 then with the foaming elastic plastic material, moulding stopper 2.At this moment, the inwall circumferential inner gear 11 of described closure outer shell 1 fits like a glove with stopper 2 one end circumference external gears 21.Interior external gear (11 and 21) mutually close fit has guaranteed that closure outer shell 1 captives joint with the circumferential of stopper 2; The expansion friction force of foaming elastic plastic material has guaranteed that the axial restraint of closure outer shell 1 and stopper 2 is connected.So back and forth during plug, closure outer shell 1 can not produce with stopper 2 separates bottle stopper at bottleneck.Because closure outer shell 1 is a hard plastics, when opening bottle stopper, can control closure outer shell 1 effectively and the unlatching bottle stopper, easy to operate; Because stopper 2 is the foaming elastic plastic material, can guarantee the sealing property of bottle stopper, and at bottleneck back and forth during plug, stopper 2 can not fall chip, fragmentation, cracking; In the environment of humidity, can not go mouldy.The inner gear 11 of the inwall circumference of described closure outer shell 1 is more than or equal to 2 teeth; The number of teeth of one end circumference external gear 21 of described stopper 2 is also corresponding to 2 teeth.(being 30 teeth among the figure).
Claims (3)
1. a bottle stopper comprises closure outer shell and stopper, and described closure outer shell envelopes stopper, it is characterized in that: described closure outer shell is a hard plastics, and described stopper is the foaming elastic plastic material.
2. bottle stopper according to claim 1 is characterized in that: the inwall circumference of described closure outer shell is provided with internal tooth, and an end circumference of described stopper is provided with external tooth, the connection that is meshing with each other of interior external gear.
