Description
Technical Field
The invention relates to the technical field of sealed plastic tanks, in particular to an easy-to-pull type sealed plastic tank with self-locking and sealing functions.
Background
Plastic cans are small packaging containers made of plastic or plastic-based materials, typically with a sealable can lid. With the rising packaging cost of pop-top cans such as aluminum cans and tinplate cans, the conventional pop-top cans are opaque, and the consumers cannot observe the contents in the package. Plastic packaging cans are coming out of the market in such a background. Plastics packing jar uses PET as the material, and is lighter than traditional easy open can, more does benefit to remote transportation, and the extranal packing is transparent, through the effective combination with some transparent labels, makes the product look very dynamic and pleasing to the eye, and the consumer can be closely observed the product simultaneously, and consumption experience is more perfect. Therefore, the plastic packaging can is popular, and a professional plastic packaging can manufacturer is provided at home. For the development of the market, perfect optimism considers that people need a plastic packaging tank product with exquisite package, good sealing performance, simple and convenient use and lower cost, and the growth of the market is a necessary trend.
The sealing mode that plastic tank adopted in the existing market has following several problems:
the first is a plastic can with a direct screw-on lid, which has poor sealing effect, and the lid is easy to be opened by theft, which easily causes the theft, loss or pollution of the goods in the can.
The second kind is the plastic tank that uses metal covering or metallic film to seal, and this kind of jar accessory is many, and sealed needs special sealing equipment, and metal covering and special sealing equipment price are high, and is with higher costs, and it is all inconvenient to use the debugging, because the lid is metallic, the lid will influence the transparency of whole jar, and the whole bandwagon effect of product is relatively poor moreover.
Disclosure of Invention
The invention aims to solve the defects in the prior art, and provides an easy-to-pull sealing plastic tank with self-locking and sealing functions.
In order to achieve the purpose, the invention adopts the following technical scheme:
the pop-top sealed plastic can with the self-locking and sealing functions comprises a can body and a cover, wherein a can opening is formed in the top of the can body, outer locking teeth and external threads are arranged on the outer wall of the can opening, the outer locking teeth are located on the lower side of the external threads, a pull ring is arranged on the outer wall of the cover, gaps are easy to tear and are formed in the outer wall of the cover and the two sides of the pull ring, the inner wall of the pull ring is located on the two sides of the gaps easy to tear and is provided with a thin-wall area, inner locking teeth are arranged above the inner wall of the pull ring, the outer locking teeth are matched with the inner locking teeth mutually and form an interlocking stopping structure jointly, inner walls of the cover are provided with cover inner.
Further, the inner wall top of lid is provided with sealed constant head tank, be provided with rubber seal in the sealed constant head tank.
Further, the easy-tearing gap is formed in the two sides of the edge of the pull ring and the edge of the cover, and the thin-wall area is arranged on the edge of the inner wall, connected with the cover, of the upper edge of the pull ring and connected with the easy-tearing gap.
Furthermore, the sealing positioning groove in the cover is arranged on the periphery of the top end of the tank opening, and the rubber sealing ring is in mutual extrusion contact with the top end of the tank opening.
Further, the internal and external threads may each be a discontinuous segmented structure.
Compared with the prior art, the invention has the beneficial effects that:
1. when the can is sealed, the cover is screwed on the can opening by external force, so that the sealing and anti-theft functions of the can be completed, the loss and pollution of articles in the can are avoided, and the integral operation is convenient.
2. The sealing can simultaneously complete the sealing and anti-theft self-locking functions only through the cover and the can body, and has a simple integral structure.
3. The invention only has two parts of the cover and the can body, and the cover and the can body can be made of the same material without special sealing equipment for auxiliary sealing and other auxiliary accessories, so the cost is low.
4. The can opening device adopts the rubber sealing ring for sealing, has simple structure, low cost and good sealing effect, can open the can by directly tearing the pull ring on the cover, and has simple and convenient operation.
6. The invention can be made into a full transparent can because the can is sealed without using a metal cover or a metal film, the whole display effect of the content in the can is very good, and the purchasing desire is increased.
7. The outer locking teeth at the can mouth and the inner locking teeth at the cover can form an interlocking and retaining structure after the cover and the can mouth are tightly closed, and the locking structure can be only tight but not loose. After opening the can by opening the tab, the lid can be sealed again for multiple seals.
In conclusion, the pot can realize convenient, quick and stable opening and closing through the structural design of the pot body and the cover, has good self-locking anti-theft opening effect, is simple in structural design, convenient to operate, high in sealing performance and low in cost, and is worthy of advocation.
