Description

Easily-torn cover reliable in sealing and container

Technical Field

The utility model relates to an easily tear the lid, concretely relates to it is sealed reliable easily to tear lid and container.

Background

At present, food packaging cans generally comprise a can body and a cover body, wherein the can body is generally an iron can, and the cover body is generally made of tinplate or aluminum plates. The lid usually includes the annular apron that is connected with the jar body, be equipped with the opening on the annular apron, the opening coats and is stamped the sealing film (easy tear film) of being convenient for to open, easily tear and cover the packing container's of food such as lid mainly used splendid attire nut, dried fruit, the biscuit, milk powder, bird's nest top cap, its lid adopts material such as tin plate or aluminum plate usually, the annular apron is usually inside and outside both sides can set up corrosion protection coating, outside coating can carry out the adhesive coating of heat-seal with easy tear film usually, the coating of annular apron inner wall can not be used for carrying out the heat-seal bonding with easy tear film usually. The lid is usually with metal material stamping forming, and the opening department of punching a hole is comparatively sharp, in order to avoid the scratch, and the inboard of annular apron adopts the turn-up design usually, is about for the inboard bending of annular apron to be the arc, and the incision is direct not expose outside, and easy dyestripping lid is arranged in the annular apron. The structure has little influence when dry food or oily medium is packaged, but when other food containing liquid is stored, the liquid medium can enter the curling part along with bending, and because protective measures such as coating supplement and the like are not carried out on the notch, the corrosion phenomenon such as rusting and the like can occur after the liquid is met, and the corrosive liquid can flow back to the container to secondarily pollute the food. The existing method is to change the cover body into an aluminum cover to avoid the corrosion problems such as rusting when the notch of the taking hole meets liquid, but the iron-aluminum galvanic corrosion also exists when the tank body is an iron tank, and the aluminum is exposed to the high-acid and high-salt environment and is corroded, so the effect is not good, and the cost is greatly increased.

In the figure, 1, a cover body; 2. easy-to-tear film; 3. an opening part; 4. A first connection portion; 5. a scratch-resistant portion; 6. a first seal portion; 7. a second seal portion; 8. a reinforcing portion; 9. a gap; 10. A sealing surface; 11. a second connecting portion.

Detailed Description

The embodiments of the present invention will be further explained with reference to the accompanying drawings:

by figure 1 combine as shown in figures 2-3, a container, including the vessel with sealed reliable easily tear the lid, sealed reliable easily tear the lid and the vessel mutually support and form the holding chamber that is used for the holding material, sealed reliable easily tear the lid including lid 1 and easily tear membrane 2, lid 1 on be equipped with opening 3, be equipped with first connecting portion 4 on the lid 1, the tip of first connecting portion 4 is bent and is formed in proper order and prevent scraping portion 5 and first sealing 6, prevent scraping portion 5 be arc and towards the opening setting, easily tear membrane 2 cover on opening 3 and be connected the realization opening 3 sealed with first sealing 6. The beneficial effects of the utility model are that, form sealedly in first sealing, avoid the internal liquid of jar to get into the tail end of first connecting portion and corrode the lid for product sealing performance is good, and the security is high. Specifically, the first sealing portion is formed by being turned (bent) on the inner wall of the lid body, and the second sealing portion is formed on the outer wall of the lid body. Specifically, a second sealing portion 7 is disposed on the outer surface of the cover body 1, and the easy-to-tear film 2 covers the opening portion and is connected with the first sealing portion 6 and the second sealing portion 7 respectively to seal the opening portion 3. Easy dyestripping realizes reliably sealedly through first sealing and second sealing, thereby it is effectual to make the product seal, the second sealing is current seal structure and mode, the setting up of first sealing makes the product avoid jar liquid in the body (container) to enter into incision hem portion, thereby avoid the lid of hem portion to be corroded, the product packaging of more types of ability adaptation, especially need the high temperature steaming and boiling food of disinfecting, have sealed reliable when liquid food packs, the high characteristics of security.

The first sealing part 6 is provided with a sealing surface 10 which is relatively horizontally arranged, and the sealing surface 10 is provided with an adhesive which is convenient for sealing. In particular, the horizontal width of the sealing surface 10 is greater than 1mm. Typically, the width of the sealing surface is 1.5mm to 2mm. More specifically, the adhesive is an epoxy phenolic coating. Specifically speaking, when production was easily torn the lid, the adhesive passed through the bonding of location coating technique at the inner wall of lid, and this first connecting portion of this department can upwards overturn after bending to set up, the easy dyestripping heat-seal of being convenient for.

The inner wall of first connecting portion 4 outwards bends and forms in proper order and prevents scraping portion 5, first sealing 6 and rib 8, first sealing 6 and second sealing 7 between be equipped with clearance 9, easy tear film 2 cover in clearance 9 top and fixed mutually with first sealing 6 and second sealing 7 respectively. Specifically, the first sealing portion 6 and the second sealing portion 7 have the same level. Specifically speaking, when production was easily torn the lid, the adhesive passed through the bonding of location coating technique at the inner wall of lid, and this first connecting portion of this department can upwards overturn after bending to set up, the easy dyestripping heat-seal of being convenient for. Such structure is comparatively level and smooth when easily tearing the membrane and covering and go, and wherein the sealed position main seal of second, the auxiliary seal of first sealed position mainly avoids liquid can get into clearance department, realizes double-deck sealed like this, and sealed effectual, and the lid is difficult to be corroded, low in production cost, does the utility model discloses an optimal mode. Of course, the width of the sealing surface can be increased in the actual production process, namely, the first sealing surface is used as a main seal, so that the product is sealed reliably.

The cover body 1 is provided with a second connecting part 11 connected with the container body, and the horizontal height of the top end of the second connecting part is higher than that of the second sealing part 7. Such structure is convenient for lid and container to be connected, and easy tear film "hides" in the inslot that the second connecting portion formed, and the product is more pleasing to the eye, is difficult to damage for product long service life.
