Description

Liquid container with interlock valve

The utility model belongs to packing container, relates generally to industrial packing liquid device.

The liquid package container of prior art, the overwhelming majority are that filling exit and leakage fluid dram are same structure.No matter the container of this structure is to be used to pack which kind of liquid, after packaged liquid uses up, container can also other similar or non-similar liquid of can, because structure, color, form and the trade mark of packing container, all represent the feature of former packaged liquid, the container after using up is other liquid of can once more, and having caused packing container liquid is the illusion of primary liquid, cause opportunity for the behavior of making, selling fake products, caused infringement for former packaged liquid production sellers.For solving packing container not by the problem of re-filling, by literature search and market research, existing a part of packing container has solved the problem that prevents re-filling, but its structure still is traditional can and discharge opeing is same opening, the way that prevents re-filling is after the can various forms of easy-open lid are shut or be made into to this opening, anti-counterfeiting cover, or rely on the sharp weapon enforced opening, destroy packing container, this has caused inconvenience for some users.These containers must once use up once unlatching, energy repeated use after being difficult to accomplish open, and can airtight container.A lot of packaged liquid are packed with industrial miniature liquids such as lubricating oil, mechanical oils, civilian food oil, liquid food condiment, test reagents as automobile, and major part needs repeated use just can use up.Existing non-returnable container can not solve and can prevent that two hand over can, can seal preservation again, and nonexpondable problem.

The purpose of this utility model provides and a kind ofly can prevent the packing container repeated usage, can make things convenient for the packaged liquid repeated use can also leak free interlocking valve liquid package container again.

The utility model adopts on the housing and establishes upper and lower two openings, valve core link rod is set in housing, the tapered core valve of valve core link rod bottom bonded assembly cooperates with the taper leakage fluid dram of housing bottom, the top fixed stop of valve core link rod, and the top of valve core link rod links to each other with loam cake.

Valve core link rod is a hollow structure, on the top of loam cake bottom and tapered spool deflation hole and its internal communication is arranged respectively.There is outside thread on surface at tapered spool, matches with tapered leakage fluid dram surface negative thread.

Interlocking valve liquid package container of the present utility model; can be made into the liquid package container of plastics below 10 liters or sheet metal shell; after the liquid of container packaging uses; container can't other liquid of re-filling; play the self-protection effect for brandname products; prevent the re-filling of fake products, protection producing and selling and customer's legitimate rights and interests.In addition, because the liquid of interlocking valve liquid package container packaging can repeatedly discharge in batches, and do not damage packing container, thereby can in the shelf-life of packing liquid, left in liquid by repeated use.And, because the utility model adopts the structure of container bottom discharge liquid, thus bring convenience to the user, and clean hygiene, accurate measurement.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model.

Among the figure: 1 loam cake, 2 packing rings, 3 blocks, 4 valve core link rods, 5 housings, 6 tapered spools, 7 tapered leakage fluid drams, 8 bases

Establish two openings of can and discharge opeing on the housing 5, valve core link rod 4 is arranged between two openings in housing 5, valve core link rod 4 and tapered spool 6, block 3 is connected with loam cake 1, no matter be can or discharge opeing, two opening interlocks are opened or sealing, sealing problem during with assurance re-filling and repeated use.When liquid production can enterprise, packing liquid poured into container after, loam cake 1 and valve core link rod 4 be bonded as one to get final product.During use, as long as rotation loam cake 1, by carrying in loam cake 1 drive valve core link rod 4 and 6 rotations of tapered spool, liquid in container will be discharged from the tapered leakage fluid dram 7 of container bottom.In the time of need stopping, only needing the opposite spin loam cake, valve core link rod will drive tapered spool 6 will with the screw thread fit of tapered leakage fluid dram 7, when loam cake slides into the upper opening of container plane 1 time, can reach the purpose that stops discharge opeing and airtight container.

Suppose the non-original packing liquid of can, owing to only leave deflation hole between upper opening of container and the valve core link rod, the gap is less, and be fixed with block 3 on valve core link rod top, valve core link rod 4 can not all propose container, so want the stifled discharge opeing end opening of going up, is impossible from re-filling suitable for reading.Want from tapered other liquid of leakage fluid dram 7 cans, loam cake must be in opening, and filling liquid will inevitably be from the gap leakage current between the deflation hole on the valve core link rod of lifting container oral area position and mouth and the valve core link rod once more, and anti-can also is impossible.

Claims (3)

1, a kind of interlocking valve liquid package container, comprise housing 5, loam cake 1 and base 8, it is characterized in that having on the housing 5 upper and lower two openings, between two openings valve core link rod 4 is set in the housing 5, valve core link rod 4 bottom bonded assembly taper valve cores 6, cooperate with the taper leakage fluid dram 7 of housing 5 bottoms, the top fixed stop 3 of valve core link rod 4, and the top of valve core link rod 4 links to each other with loam cake 1.

2, interlocking valve liquid package container according to claim 1 is characterized in that valve core link rod 4 is hollow structure, has deflation hole to be communicated with it respectively on the top of loam cake 1 bottom and taper valve core 6.

3, interlocking valve liquid package container according to claim 1 is characterized in that the surface of taper valve core 6 has screw thread to match with taper leakage fluid dram surface negative thread.
