Abstract
The utility model relates to a can bottle cover, in particular to a rotary open-type can cover, concretely a pressure-reducing can bottle cover, comprising a bottle cover body. The bottle cover body is provided with a pressure-reducing vent, and a sealing plug, the part of which is positioned on the upper part of the surface of the bottle cover body, is arranged in the pressure-reducing vent; that is the sealing plug is arranged in the pressure-reducing vent, and the part of the sealing plug is exposed on the upper part of the bottle cover outside the bottle cover. The sealing plug is composed of an upper plug body positioned on the upper part of the bottle cover body and a base pad which is fixedly connected with the upper plug body and fixed with the inner surface of the bottle cover body; the sealing plug can also be composed of an outer plug body with a hole in the center and an inner plug inserted in the hole of the outer plug. Compared with the prior art, the utility model changes the shape and the structure of the sealing plug in the pressure-reducing vent and makes the can bottle cover opened without any tools, and the decompression of the can and the opening of the bottle cover can be easily realized only by hands. The utility model has artful design, simple structure and convenient use.
Description
Technical field
The utility model relates to a kind of can bottle cap, particularly rotary open type can bottle cap, is specially a kind of decompression type can bottle cap.
Background technology
When opening can, generally need to prize bottle cap with screwdriver or other opener earlier, bottle cap is just opened in venting easily in Cans.If be away from home, suffer from and do not have suitable opener on hand, give the unlatching of can, edible making troubles.
For making things convenient for the unlatching of can, the prior art employing covers at Cans makes a call to an aperture, adheres to a packing seal at the back side in hole, when opening can, at first packing seal is disclosed out with prong, and venting in Cans, decompression, thus Cans are opened easily.Because packing seal sticks to the back side of can bottle cap, hand that do not expose outside the can bottle cap, available is the sealing member of unpacking directly in the prior art, still needs by certain instrument during Tin opener, and the unlatching of Cans still is not convenient especially.
Summary of the invention
The utility model solves to be needed by special tool when existing can bottle cap is opened, can not directly open with hand, and then brings Tin opener, edible inconvenient problem, and a kind of unlatching can bottle cap especially easily---decompression type can bottle cap is provided.
The utility model is to adopt following technical scheme to realize: decompression type can bottle cap, comprise bottle cap body, and on bottle cap body, have a vent, be provided with the sealing plug that its part is positioned at the bottle cap body upper surface in the vent; Some is the bottle cap top that is exposed at outside the bottle cap promptly to be provided with sealing plug and sealing plug in vent.Like this, when opening can, scratch the sealing plug part that firmly is positioned at bottle cap top with hand, sealing plug is plucked out in vent, air is realized decompression in the bottle in vent enters Cans, bottle cap is opened easily.
The utility model has compared with prior art changed the shape and the structure of sealing plug in the vent, need not by any instrument when the can bottle cap is opened, and only with hand just can be realized the decompression of can and the unlatching of bottle cap easily.It is skillfully constructed, simple in structure, very easy to use.
Description of drawings
Fig. 1 is a kind of concrete structure scheme drawing of the present utility model;
Fig. 2 is an another kind of concrete structure scheme drawing of the present utility model;
The specific embodiment
Decompression type can bottle cap comprises bottle cap body 1, has a vent 2 on bottle cap body, is provided with the sealing plug that its part is positioned at the bottle cap body upper surface in the vent.
Sealing plug is connected by the last cock body 5 that is positioned at bottle cap body top with last cock body and constitutes with the fixing heelpiece 6 of bottle cap body inside face.Sealing plug is made with elastomeric material, and the antirust glued membrane that can stick with glue between last cock body 5 and the heelpiece 6 and between heelpiece 6 and the bottle cap body inside face or directly apply with existing bottle cap body inside face is as heelpiece.During actual fabrication, cock body 5 also can directly be put on vent on the rubber, after cock body solidifies on the rubber promptly with the heelpiece adhesion.Or will go up cock body earlier and fill in vent, then with glue with heelpiece and last cock body and bottle cap body inside face cementation.
Sealing plug has the outer plug 3 in hole by the center and the interior plug 4 that inserts in the outer consent constitutes.The available rubber of outer plug is made, and the available hard material of interior plug such as plastics, bakelite etc. are made, and the external diameter of plug in the internal diameter in hole beyond the Great Wall can be slightly less than outward makes to form between Nei Sai and the outer plug to closely cooperate.When bottle cap is opened, earlier interior plug is transferred in the hole of outer plug, will be filled in outward in vent again and transfer to.Another benefit of the sealing plug of this kind structure is after bottle cap is opened, and the continuation that does not influence bottle cap after sealing plug resets is again used.
During actual the use, can on sealing plug, stick on sealing band, to prevent the artificial destruction before the opening by mistake or sell of sealing plug.Part on the bottle cap body 1 around the vent caves inward.Make the top of sealing plug basic fair, like this, help sticking on sealing band on the top of sealing plug with the bottle cap body upper surface.
