Description

A kind of seal cover cap

The utility model discloses a kind of seal cover cap, and particularly suitable uses in the sealing of vessel port, belongs to the improvement of packing technique.

At present, when small containers such as accumulating food, medicine and chemical are packed on the market, adopt the spinning type seal cover cap, how by the stamped metal moulding more, sticking on diaphragm seal by vessel port stop portion end face compresses through spiral and seals packing, this kind manner of packing not only will expend a large amount of metallic materials, and complex process, and difficulty of processing is big, the cost height, and the sealing accumulating effect in actual the use is unsatisfactory, and the corrosion of stock is rotten to happen occasionally, and these all should be solved.

The purpose of this utility model is exactly the adopted cheap material manufacturing that proposes at the problems of above-mentioned existence, and processing is simple, and cost is low, a kind of seal cover cap of storage good sealing effect.

Above-mentioned purpose of the present utility model is to realize with a kind of seal cover cap of employing brand new design-calculated the utility model of cheap plastic material manufacturing, it is by lid top panel, compositions such as tegmental wall plate, it is characterized in that: on the outer peripheral wall of tegmental wall plate stop portion, be provided with an annular thickening layer, the lateral wall of this thickening layer is provided with the threaded cylindric lug of extension radially, on the tegmental wall plate, cross in lug line of centers and the plane, cover plate center of gyration line place and leave gap length, on the lug screw thread, be installed with wing nut, on the interior peripheral wall face of tegmental wall plate, amplexiformed diaphragm seal, annular thickening layer on the use middle cover wallboard of reality both can be made into integration with the tegmental wall plate, also can establish the assembling of thickening ring in addition and make; Be in the cap seal container, the gas in the container to be stopped discharge during use, on the perisporium on the tegmental wall plate, also radially have through hole, again the hole is shut after encapsulation is bled and to realize failure-free security seal packing.

A kind of seal cover cap of embodiment

Present embodiment is in the can canned apple packing, to use a kind of embodiment of the utility model seal cover cap made of plastic in the stepped cylindrical glass bottle of tool circular port.The present embodiment seal cover cap is by lid top panel (1), tegmental wall plate compositions such as (2), it is characterized in that: the outer peripheral wall of tegmental wall plate stop portion is provided with the annular of making one and does thick-layer (3), the outer side surface of this thickening layer is provided with the threaded cylindric lug (6) of extension radially, in going up lug (6) central axis and lid plane, center of gyration line place, tegmental wall plate (2) was provided with gap length (5), on the lug screw thread, be installed with wing nut (7), in the tegmental wall plate, amplexiformed sealed Cellophane (4) on the peripheral wall face, on tegmental wall plate perisporium, radially have a through hole (8), during packing on the can bottleneck after the can directly with the seal cover cap buckle closure on bottleneck, at this moment produce under the resilient pressure effect at the tegmental wall plate, sealed Cellophane can tightly be tightly connected side ring surface in bottleneck and the tegmental wall plate together, air can be sealed with glue after aspirating hole (8) is discharged in the bottle simultaneously, then can finish package encapsulation work, when when opening the bottle seal cover cap, as long as the interval appears heavily again in the slit that wing nut is screwed out on the tegmental wall plate then, at this moment the tegmental wall plate just is easy to be removed to the stress relaxation of bottleneck neck.

In using, the utility model has the following advantages: by the sealing of the utility model seal cover and bottleneck No longer adopt the spiral compression formula, so bottle all becomes very simple with the manufacturing of covering, can make cost greatly Reduce, and owing to sealing surface in using amplexiforms tightly, so good refreshing effect, long shelf-life, favourable Storage and transportation, simultaneously unlatching is also very convenient, and bottleneck does not have the damage phenomenon, can save again a large amount of simultaneously Metal, its economic results in society all are very significant.

Claims (3)

1. seal cover cap, it is made up of lid top panel, tegmental wall plate etc., it is characterized in that: on the outer peripheral wall of tegmental wall plate stop portion, be provided with an annular thickening layer, the lateral wall of this thickening layer is provided with the threaded cylindric lug of extension radially, on the tegmental wall plate, cross in lug line of centers and the plane, cover plate center of gyration line place and leave gap length, on the lug screw thread, be installed with wing nut, on the interior peripheral wall face of tegmental wall plate, amplexiformed diaphragm seal.

2. according to the described seal cover cap of claim 1, it is characterized in that: the annular thickening layer on the tegmental wall plate both can be made into integration with the tegmental wall plate, also can establish the assembling of thickening ring in addition and make.
