Abstract
A liquid bottle neck leak-stopping apparatus comprises an outer cover casing and a leak-stopping surrounding edge. The connecting face of the outer cover casing and the leak-stopping surrounding edge are a top part sealing face. A protruding loop is arranged on the top part sealing face in the place corresponding to a liquid bottle neck. The internal hole of an inner plug sleeves a core rod and forms a circular groove. The internal wall of the circular groove and the leak-stopping surrounding edge are connected to form a sealing structure. The external wall of the circular groove and the inner wall of the liquid medicine bottle neck form another sealing structure. The top part of the groove is provided with a reverse-direction back-buckling type sealing groove. The top part of the sealing groove is fitted with the protruding loop of an outer cover. When the outer cover is screwed onto the liquid bottle neck tightly, the liquid bottle neck is plugged into the back-buckling type sealing groove of the inner plug, and the inner plug is presses in the protruding loop of the outer cover tightly for sealing. The liquid bottle neck leak-stopping apparatus is advantaged by multiplex sealing and good sealing effect.
Description
Technical field
The utility model relates to sealing means of bottleneck, particularly a kind of liquid bottles bottleneck leak stoppage device sealing for liquid medicine water bottle.
Background technology
The hermetically-sealed construction of liquids in general liquid medicine bottleneck is to adopt thread connecting mode to be connected by enclosing cover and bottleneck, and in it, plug is unreasonable with the hermetically-sealed construction of bottle cap, conventionally there will be the phenomenon of leakage, and impact is used.
Utility model content
The purpose of this utility model is just to provide the liquid bottles bottleneck leak stoppage device that a kind of leak tightness is strong.
This practicality can novel solution be such: the utility model comprises outer cover case and leak-stopping surrounding edge, the joint face of outer cover case and leak-stopping surrounding edge is top seal face, there is flange collar this top seal face and liquid bottles bottleneck corresponding position, described interior plug endoporus socket plug also forms circular groove, the internal diameter of described circular groove and leak-stopping surrounding edge connect into hermetically-sealed construction, and its external diameter and liquid medicine internal diameter of the bottleneck connect into hermetically-sealed construction; Described groove top has the seal groove of reverse returning formula, match with the flange collar of enclosing cover in the top of described seal groove, in the time that enclosing cover is tightened in liquid bottles bottleneck, in liquid bottles bottleneck inserts, in the returning formula seal groove of plug, the flange collar that chock off is pressed in to enclosing cover seals.
Technical scheme also comprises more specifically: described interior plug is flexible material.
The utility model has the advantages that employing is multi-sealed, good sealing effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model enclosing cover 3.
Fig. 2 is the connection structure schematic diagram of the interior plug 4 of the utility model and plug 5.
Fig. 3 is the structural representation after the utility model assembling.
The specific embodiment
As shown in Figure 1, described enclosing cover 3 comprises outer cover case and leak-stopping surrounding edge 2, the joint face of outer cover case and leak-stopping surrounding edge 2 is top seal face, there is flange collar 1 this top seal face and liquid bottles bottleneck corresponding position, described interior plug 4 endoporus socket plugs 5 also form circular groove, the internal diameter of described circular groove and leak-stopping surrounding edge 2 connect into hermetically-sealed construction, and its external diameter and liquid medicine internal diameter of the bottleneck connect into hermetically-sealed construction; Described groove top has the seal groove of reverse returning formula, match with the flange collar 1 of enclosing cover 3 in the top of described seal groove, in the time that enclosing cover 3 is tightened in liquid bottles bottleneck, in liquid bottles bottleneck inserts, in the returning formula seal groove of plug, the flange collar 1 that interior plug 4 is pressed on to enclosing cover seals.
For sealing better, described interior plug 4 is flexible material, as rubber, plastics etc.
Said structure, forms following three kinds of hermetically-sealed constructions:
1, the first structure sealing with the reverse returning formula seal groove of interior plug 4 of liquid bottles bottleneck;
2, the spinning hermetically-sealed construction that the flange collar 1 of enclosing cover 3 and interior plug 4, liquid bottles bottleneck form;
3, leak-stopping surrounding edge 2 forms circular muff-coupling sealing structure with interior plug 4.
Above-mentioned three kinds of hermetically-sealed construction combineds action, reach good leakage-proof effect.
Claims (2)
1. a liquid bottles bottleneck leak stoppage device, comprise the enclosing cover (3) being connected with liquid bottles, the interior plug (4) being connected with enclosing cover and through the plug (5) of interior plug, it is characterized in that: described enclosing cover (3) comprises outer cover case and leak-stopping surrounding edge (2), the joint face of outer cover case and leak-stopping surrounding edge (2) is top seal face, there is flange collar (1) this top seal face and liquid bottles bottleneck corresponding position, described interior plug (4) endoporus socket plug (5) also forms circular groove, the internal diameter of described circular groove and leak-stopping surrounding edge (2) connect into hermetically-sealed construction, its external diameter and liquid medicine internal diameter of the bottleneck connect into hermetically-sealed construction, described groove top has the seal groove of reverse returning formula, match with the flange collar (1) of enclosing cover (3) in the top of described seal groove, in the time that enclosing cover (3) is tightened in liquid bottles bottleneck, in liquid bottles bottleneck inserts, in the returning formula seal groove of plug, the flange collar (1) that interior plug (4) is pressed on to enclosing cover seals.
2. liquid bottles bottleneck leak stoppage device according to claim 1, is characterized in that: described interior plug (4) is flexible material.
