Abstract
" vacuum easy-opened can " is that a kind of sealing back extraction inner air makes it become vacuum state, thereby utilizes external pressure to make the principle of lid and tank body pressing, can be used as the numerous food can.When edible, as long as the plug core that will cover is left behind beyond the Great Wall from aspirating hole, air promptly enters in the jar, and jar can be opened.Characteristics of the present invention are: 1. easily draw back; 2. material can be glass, pottery, metal or plastics.So cost is low, easily promote; 3. inner vacuum is aseptic, does not need anti fouling composition, and food is not perishable; 4. because of no weld seam, former unleaded; But 5. the equal repeated use of tank body and lid, no waste.
Description
The invention belongs to canned food container manufacture technology field, is a kind of portable pop can.Domestic its sealing of food vacuum accumulating jar (Chinese utility model CN2030582U) at present is to use the barometric pressure principle, and the soft lid that butyl rubber is made tightens on soft jar mouthful, goes up stiffening ring of tensioner for soft jar mouthful, makes a jar mouth become rigidity.Need join during use and take out inflation pump.Its bleed mouth structure and package unit are comparatively complicated, so this is a kind of similar refrigerator and be different from the antistaling vacuum container of portable food can.The domestic in addition jar pop can that has used draws back remainder after edible and still remains in and be difficult on the glass bottle opening take off so be not easy to reclaim repeated usage.
The object of the present invention is to provide a kind of simple, no waste, thus portable easy-open lid can free from environmental pollution.
Its structure system is made up of with the plug core (5) that metallic material is manufactured the rubber stopple (4) on tin-plate lid (1), glass tank body (2), rubber seal ring (3) and the lid (1).Be the assurance favorable sealing property, the joint portion of this tank body of container and lid, the joint portion of stopple and pore (6) is designed to have garden cone angle structure, and the preceding stopple (4) of bleeding is pressed into pore (6), inserts tensioner with plug core (5) again, guarantees sealing.Carry out in the slit of bleeding through between stopple and lid.After bleeding, inner only be the water saturation air pressure normal temperature under, the rubber seal ring of atm difference by the centre that acts on rigid cap and the tank body is combined into one it, and covers and tank body direct contact not.When edible, to pull out in plug core (5) the air admission jar, lid can be upspring voluntarily.
Sealing property is as follows: contain pears in syrup 0.5kg in the container (covering 50 millimeters of diameters) with said structure, can bear 15 kilograms of pulling force through test after sealing is found time, seal to test once more after 1 year and still can bear 15 kilograms of pulling force.Can use as can to guarantee strict seal.
The characteristics of this vacuum pop can:
1. lid easily draws back, and pulls out the plug core, and lid is upspring automatically.2. jar and cover reusable, no waste, thus greatly reduce the rubbish of contaminated environment.3. jar and interior dress food are owing to boil, find time.So anaerobic, aseptic, food is not perishable.4. there is not weld seam, so unleaded.5. the material of tank body and lid can be glass, pottery, metal; Originate sufficient, cheap, cost is low.6. simple in structure, utilize the existing installation of cannery, both can process.
Claims (2)
1, vacuum easy-opened can is a kind of reusable canned food, and the rubber stopple (4) that a rubber seal ring (3) covers is put by rigid cap (1) and rigidity tank body (2) are middle by this can system, and plug core (5) is formed the back formation can integral body of finding time; It is characterized in that: rigid cap and rigidity tank body contact part all are designed to garden cone angle structure, and rigid cap and tank body direct contact not.
2, according to the described can of claim 1, it is characterized in that: rubber stopple (4) center has through hole, and a rigidity plug core (5) is housed in this hole in addition.
