Abstract

The utility model relates to an outer sealing paper pot, relating to a composite paper packing pot which is used for packing solid in the chemical industry, medical solid, powdered medicine solid for food, granule material solid, etc. The utility model is composed of an upper cover (1), a lower bottom (2), and a pot body (3), wherein, the pot body (3) is provided with a plastic film layer (4) and two or more than two composite paper layers from inside to outside; the lower bottom (2) is a piece which is made of tinplate, and the upper cover (1) is a plastic cover. Compared with a pot which is made of the tinplate, the utility model has the advantages of water proof and moisture proof. Compared with the present paper pot, the utility model in which a condensation phenomenon or a steam film layer does not exist because of environmental change extends the valid storage period of a packed object.

Description

Outer sealed papaer pot

The utility model relates to the composite packing paper jar of solids such as a kind of packaging chemical, medicine, food pulvis or pellet.

Existing paper can generally adopts tank body for protection against the tide and is from inside to outside: the structure of plastic film or waterproofing coating, ply of paper, wrapping film or coating.Because of plastic film or the no hygroscopic character of waterproofing coating itself, when variation of ambient temperature, its tank inner surface can form condensation, thereby influences the storage period of packaged product.

The purpose of this utility model is: provide a kind of and can effectively improve the outside face sealed composite paper can that tank inner surface can form the defective of condensation.

The utility model comprises loam cake (1), goes to the bottom (2) and tank body (3), and tank body (3) is from plastic membranous layer (4) and two layers or more paper composite bed are arranged outside to inside.This plastic membranous layer (4) available heat shrinkable film, loam cake can be used plastic part, goes to the bottom and makes with metallic materials such as tin-plates.

The utility model is inexpensive than can, and is waterproof and dampproof, overall appearance and with existing paper can ratio, can not occur condensation or steam rete in the tank body, thereby prolong effective storage period of packed article.

Below in conjunction with embodiment the utility model is illustrated in detail.

Accompanying drawing 1 embodiment integral structure figure.

The partial enlarged drawing of accompanying drawing 2 embodiment 1.

The partial enlarged drawing of accompanying drawing 3 embodiment 2.

As Fig. 1, Fig. 2, it comprises loam cake (1), goes to the bottom (2) and tank body (3), and tank body (3) is blank sheet of paper layer (5) from inside to outside, yellow plate paper layer (6), the heat-shrinkable film of color printing (4).Loam cake (1) is a kind of vinyon lid, and go to the bottom (2) are the tin-plate product, and tank body (3) is made the bobbin shape by compound good ply of paper, again with after go to the bottom (2) cooperate, be inserted in thermal contraction periosteum (4) through color printing, heating back heat-shrinkable tube film wrapping on the tank body tightly, bright and clean, open and flat.

As Fig. 1, Fig. 3, it comprises loam cake (1), goes to the bottom (2) and tank body (3), and tank body (3) is blank sheet of paper layer (5), yellow plate paper (6), color printing wrapper (7), heat-shrinkable film (4) from inside to outside.Loam cake (1) is a kind of vinyon lid, go to the bottom (2) for the tin-plate product, tank body (3) is by compound good blank sheet of paper layer, the compound bobbin of making of yellow plate paper layer, after outside stickup one deck is printed on the wrapper of product labelling, (2) cooperate with going to the bottom, be inserted in the thermal contraction periosteum then, promptly make the utility model through heating.With pulvis, pellets such as the utility model packaging chemical, medicine, food, air-tightness was good after loam cake sealed with the film band.Or, add loam cake with behind plastic film or the aluminium pool composite material sealed shell of tank mouth.The utility model is deposited tealeaves etc. and is also had preservation.
