Description

Metal can sealed by aluminum foil

Technical Field

The utility model relates to a metal package technical field especially relates to a metal can with aluminium foil bonding sealing.

Background

Use the aluminium foil to easily tear the lid and seal and be a mode of sealing that tinplate can was commonly used, the aluminium foil easily tears the lid and comprises tinplate lid circle and aluminium foil, easily tears and covers the production process and include: 6 processes of tinplate cover ring production, cover feeding, punching, curling, aluminum foil stamping and aluminum foil sealing are carried out, when the can is manufactured, the can body and the easy-to-tear cover are sealed in a double-seaming mode, the whole production and sealing process of the easy-to-tear cover is complex, and the cost of corresponding materials and matched equipment is very high; the distance between the pull ring (sheet) of the easy-tear cover and the tank opening is only 2-3 mm, one end of the easy-tear cover is sealed downwards on a filling production line, the phenomenon that the pull ring (sheet) of the easy-tear cover is clamped by filling line equipment can occur, the production efficiency is influenced, and the sealing performance of the tank body is influenced due to the fact that the aluminum foil is deformed due to impact in the transportation process of the tank body when the distance between the aluminum foil and the tank opening is small; in addition, the easy-to-tear cover is generally in an O shape or a D shape, and the opening of the easy-to-tear cover is small, so that when the content in the can is taken, a hand is difficult to extend into the can, and the content is not easy to take.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problem, the utility model provides a metal can who seals with aluminium foil bonding, its jar mouth is direct to be sealed with the aluminium foil, and aluminium foil and jar mouth pass through the mode bonding of heat-seal, easily tear lid sealing mode with the tradition and compare, do not need tin plate lid circle, need not the roll sealing technology, have simplified metal can production technology, have reduced metal can material cost, manufacturing cost to reach the purpose that energy-saving reduces the cost, for reaching this purpose, the utility model provides a metal can who seals with aluminium foil bonding, including can body and aluminium foil lid, there is the opening can body top, can body upper portion has round can body inside convex step by the opening part, the aluminium foil lid seals the can body on can body inside convex step through the mode bonding of heat-seal.

The utility model discloses a further improvement, there is the piece of tearing aluminum foil lid edge one side, tear piece and aluminum foil lid formula as an organic whole, can be convenient for the aluminum foil lid through tearing the piece and tear.

The utility model discloses a further improvement, aluminium foil lid thickness is between 0.05 ~ 0.13mm, and the aluminium foil that seals uses and easily tears a lid sealing aluminium foil commonly used are same kind of material, and thickness is between 0.05 ~ 0.13 mm.

The utility model discloses a further improvement, can body open-top's edge is the turn-up, and the design can be guaranteed like this, and the jar mouth does not have sharp edge, can not hinder consumer's hand when getting the interior product of jar.

The application relates to a metal can sealed by an aluminum foil, which has the following characteristics:

1, the top opening of the metal can is curled inwards, and an aluminum foil direct heat sealing mode is adopted during sealing, and the metal can is arranged on the step protruding inwards of the can body. The sealing mode does not need the production process of the tinplate cover ring of the easily-torn cover in the traditional can making process, can reduce the cost of can making materials, does not need the technological process of top cover rolling and sealing, simplifies the production process of the metal can, in addition, the can making process does not need expensive rolling and sealing equipment, reduces the investment of metal can production equipment, and reduces the manufacturing cost of the metal can in 3 aspects of materials, processes and equipment;

2. the method can save materials, reduce the tank manufacturing cost and the energy consumption in the metal tank production process, and achieve the purposes of energy saving and cost reduction;

3. the distance between the aluminum foil pull ring (sheet) and the can opening is 10-12 mm, so that the problem that the practical easily-torn cover is clamped by the pull ring on a filling production line can be solved, the problem that the aluminum foil is deformed by external force impact in the transportation process can also be solved, and in addition, the spoon for taking and taking the can contents is convenient to store due to the large distance between the aluminum foil and the can opening;

4. the opening of the tank body is maximized, so that the content in the tank can be taken and used conveniently, and the use experience of consumers is improved;

5, the sealing performance is the same as that of the easily-torn cover, and the sealing performance is good in the mode of direct heat sealing;

6, compared with the traditional easy-to-tear cover sealing mode, the metal can sealed by the aluminum foil has low opening force of the heat sealing film and is easy to open;

7, the metal can that the direct heat-seal of aluminium foil sealed opens the back, and the jar mouth does not have sharp edge, can not injure consumer's hand when getting jar interior product, and jar body opening diameter can not reduce because of the existence of metal ring circle, and the product is taken easily in the jar.
