Abstract

The utility model relates to a tearing type reusing bottle cover of polypropylene, particularly a bottle cover which can send out sound to increase atmosphere. The bottle cover can easily open an upper cover by using the part of an indentation line on a cover body and can be repeatedly used, and the loss of the utility model can not be worried about. An inner plug is arranged in the upper cover and can be matched with other parts of the upper cover to be tightly combined with a bottle mouth. Because the utility model is integrally formed by the injection of the polypropylene, the utility model has the advantages of no rusting, no rupture, safety, sanitation, easy production and low cost.

Description

Reusing bottle cover with tearing-strip made of polypropylene

The utility model relates to a kind of polypropylene tear-open repeated usage bottle cap, particularly a kind ofly utilizes the indentation line on the lid to open loam cake easily, and reusable, unexpected loss is dropped, and can send the sound to strengthen the bottle cap of atmosphere when uncapping.Form one owing in loam cake, be provided with Nei Sai and loam cake, can produce the air tight effect with bottle.Because of it is by the polypropylene material integral injection molding, safety and sanitation, with low cost, easy to manufacture, can produce favorable economic benefit.

The glass containers of commonly using at present need could be opened its lid by opener mostly, trouble effort very, and its bottle cap gets rusty easily and can't repeated usage, does not meet desirable requirement.Other has a kind of bottle cap is to open in the mode of screwing, though easier, carve tooth and hinder hand easily, and lid drops easily, loses, also not satisfactory.

In view of this, the utility model has designed a kind of safety, health, convenience at the various shortcoming of commonly using bottle cap, reusable again bottle cap.

Following conjunction with figs. is described in detail as follows:

Fig. 1 is a stereo appearance figure of the present utility model;

Fig. 2 is an inner structure transparent view of the present utility model;

Fig. 3 is a side cutaway view of the present utility model;

Fig. 4 is an action scheme drawing of the present utility model.

Such as Fig. 1, Fig. 2, shown in Figure 3, reusing bottle cover with tearing-strip made of polypropylene of the present utility model mainly is to be worked in coordination by a lid and a bottle to form, and its lid 1 comprises loam cake 11, connecting ring 12, retainer ring 13. Wherein loam cake 11 is a ducted body, peripheral hardware one bead 111, in establish in the ring-type its external diameter of plug 14(and decide on bottleneck 21 internal diameters), because it is external convex arc shape, can be against the inner surface of bottleneck, cooperates the effect that can seal with the bottle generation with the loam cake other parts. Connecting ring 12 connects loam cake 11 and retainer rings 13, on establish a protuberance 121, by indentation line 122, can tear easily, but not establish indentation line because connecting ring 12 still has on a junction part 123, so unlikely complete tear fracture. This connecting portion 123 is arranged at the position, opposite (being at a distance of 180 ° on the circumference) of bead 111, makes the best application of force state that loam cake is opened that is in. Retainer ring 13 is sheathed on neck part 22, has to strengthen loam cake sealing and the effect of fixing.

As shown in Figure 4, the utility model is when opening, only protuberance 121 need be pulled up, connecting ring 12 can be torn easily by indentation line 122, but because still some 123 does not establish indentation line on the connecting ring 12, so unlikely complete tear fracture, withstand bead 111 with finger and exert oneself a little, just can open loam cake 11, very easy, the external annulus of loam cake 11 inwardly pushes the outer surface of bottleneck because of the inner surface of the interior plug 14 outside roof pressure bottlenecks in the loam cake again, so still can reach the purpose of sealing when reusing. The incomplete tear fracture of connecting ring 12, mat connecting portion 123 connects loam cakes 11 and retainer rings 13, makes loam cake 11 unexpected losses. Loam cake 11 is a ducted body, because there being the event of external and internal pressure difference, can send the sound by it during unlatching, reaches the effect that increases atmosphere.

In sum, the utility model is by polypropylene material integral injection molding, and safety and sanitation are with low cost, easy to manufacture, reusable, opens simply, and can when opening, send the sound and increase atmosphere, and be the creation of a Nover practical.

Claims

1, a kind of polypropylene tear-open repeated usage bottle cap is mainly cooperated with a bottle by a lid to form, and it is characterized in that this lid comprises:

One cooperates the loam cake that can produce sealing function with bottle, is a hollow lid, its internal diameter and the driving fit mutually of bottleneck external diameter, in establish plug in the ring-type, external diameter and internal diameter of the bottleneck driving fit mutually of plug in this, other is provided with a bead that is beneficial to unlatching usefulness;

One is used to connect the coupling link of loam cake and set collar, be positioned at the loam cake below, on establish indentation line and for the protrusion puted forth effort when tearing, keep one on this coupling link and do not establish with indentation line with the part that is connected of set collar for making the incomplete tear fracture of coupling link still connect loam cake after opening;

One strengthens lid and bottleneck fixes and the set collar of sealing function, is positioned at below the coupling link.

According to the polypropylene tear-open repeated usage bottle cap of claim 1, it is characterized in that 2, the bead of said loam cake and said coupling link are not established being connected partly of indentation line, are configured in the position, opposite, promptly on the circumference at a distance of 180 °.
