Abstract

A paper can package comprises a can body with an aluminum-plastic film coated therein and a thin-film upper cover. An exposed flanged edge of the aluminum-plastic film is formed at the lower end opening of the can body, matched with the joint surface of a hard bottom cover, and jointed and sealed by heating and pressurizing. Letters and patterns can be printed on the outer side the preformed hard bottom cover, an aluminum-plastic film is coated on the inner side of the hard bottom cover, and a heat seal surface is formed in the vicinity of the edge of the hard bottom cover and matched with the flanged edge at the lower end opening of the can body.

Description

A kind of paper can packing

Technical field

The utility model relates to the packing vessel, particularly papery packing jar.

Background technology

In food service industry, the storage of some products is usually arranged, must guarantee that sealing makes moist preventing.Potato chips of being made by potato are for example generally used the canned container splendid attire of papery, and for guaranteeing its sealing property, its loam cake is the aluminium plastic membrane of one deck through blanching, lower cover be one through rolling and paper can leak free crown cap.Loam cake is to be easy to open, and by the customer through the paper bucket thing (potato chips) of getting suitable for reading.The shortcoming of this packing is: the production efficiency of compaction technology is too low, generally can only single piece work, and usually do not satisfy the needs of maker, even become the bottleneck of whole production flow process.

The utility model content

For solving above-mentioned orthodox method material cost height, shortcoming that process efficiency is low, the utility model provides a kind of paper can packing, and it is simple in structure, the production efficiency height, and can realize good sealing.

The technical scheme in the invention for solving the technical problem is: a kind of paper can packing, cover the tank body and the film loam cake of aluminum plastic film in comprising, lower port at tank body forms the flange that an aluminum plastic film exposes, and matches with faying face on the hard bottom, after heating and pressurizing in conjunction with and sealing.But preformed hard bottom outside printing word and pattern, the inboard is covered with the layer of aluminum plastic film, near moulding one heat cover its edge, and match with the lower port flange of tank body.Lower port preforming one flange of tank body, and the aluminum plastic film that covers in it is exposed, identical with the heat cover of hard bottom.When manufacturing process circulate bottom and tank body in conjunction with the time, only need both are fitted, and apply High Temperature High Pressure in both joint portions, making separately, aluminum plastic film merges and tight connection.Because heat seal process processing is simple, can realize many synchronous processings, even the processing of continous way, therefore can enhance productivity greatly.

The beneficial effects of the utility model are: simple in structure, the cost of material is low, favorable sealing property, and can realize the bigger lifting of production efficiency.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the upright figure of the group of paper can packing.

Fig. 2 is the block diagram of paper can packing.

Fig. 3 is the structure internal anatomy of paper can packing.

Fig. 4 is that of paper can packing implements illustration.

Fig. 5 is another enforcement illustration of paper can packing.

1 papery tank body among the figure, 2 hard bottoms, 3 film loam cakes, 4 over caps, 5 bottom main bodys, 6 bottoms scald film, 7 bottom adhesive layers.

The specific embodiment

By Fig. 1 and Fig. 2 as can be seen, in cover the papery tank body 1 place suitable for reading heat seal one film loam cake 3 of aluminum plastic film, be provided with an over cap 4 above.Over cap 4 can play protective film loam cake 3 not by the effect of breakage in transportation and storing process.The material of film loam cake 3 is generally aluminum-plastic composite membrane, and main body is rounded, and is provided with one for customer's strip off handle suitable for reading, conveniently to get thing.The material of over cap 4 is plastics.

Can see by Fig. 3 and Fig. 4, in the bottom of papery tank body 1, the flange of moulding one cambered surface, its in-to-in aluminum plastic film exposes simultaneously.It is one that hard bottom 2 scalds film 6 compound by bottom main body 5 and bottom.Bottom main body 5 is generally paper material, and it generally is aluminum plastic film that bottom scalds film 6.Bottom main body 5 preforming one faying face, and coincide with the flange of the bottom of papery tank body 1.Like this, the aluminum plastic film on papery tank body 1 and the bottom main body 5 fits together, and through high-temperature pressurizing, both surperficial plastic films is combined together, and reaches sealing and bonded assembly effect simultaneously.Because the paper material price is lower than metallic material, the efficient of high-temperature pressurizing technology is higher than the compaction technology of crown cap simultaneously, can realize processing synchronously or continuously of multiplex's part, therefore can realize the lifting of production efficiency.But hard bottom 2 outside printing word and patterns beautify product.Because between hard bottom 2 and the papery tank body 1, there is not the handle that can peel off for the customer, the material of hard bottom 2 is firmer simultaneously, can bear transportation and the destructive situation when putting on the shelf, guarantees to store and leak free validity.

In addition, under the situation of technology and price condition permission, the material of bottom main body 5 also can be selected plastics for use, as materials such as PVC, PP.

Fig. 5 is another embodiment of the present utility model, and combining between hard bottom 2 and the papery tank body 1 finished by the bottom adhesive layer 7 that is preformed on the bottom main body 5.The material of bottom adhesive layer 7 can be heat-sensitive glue, under the technology of high-temperature pressurizing, realizes combination and leak free effect.

Claims

1. paper can packing is covered the tank body and the film loam cake of aluminum plastic film in comprising, it is characterized in that: the lower port of tank body forms the flange that an aluminum plastic film exposes, and matches with faying face on the hard bottom, after heating and pressurizing in conjunction with and sealing.

2. a kind of paper can packing according to claim 1, it is characterized in that: the hard bottom is the complex of papery and aluminum plastic film.

3. a kind of paper can packing according to claim 1, it is characterized in that: the material of the faying face on the hard bottom is the top layer plastics of aluminum plastic film.

4. a kind of paper can packing according to claim 1, it is characterized in that: the material of the faying face on the hard bottom is a kind of heat-sensitive glue.
