Abstract

The utility model discloses a liquid packaging can and relates to a packaging can for sealing and holding liquid, and is designed to solve the problem of crack occurred in an aluminum foil layer positioned on a folding top corner of the existing liquid packaging can. The liquid packaging can comprises a packaging can body made of paper-plastic composite material with the aluminum foil layer. The packaging can body takes a shape of a cylinder or a frustum of cone. The liquid packaging can adopts the cylindrical or frustum of cone type packaging can body, and no folding top corner exists in the liquid packaging can, thereby ensuring no occurrence of the crack of the aluminum foil layer of the paper-plastic composite material, and the pollution to the liquid positioned inside the packaging can caused by bacteria entering the packaging can is more effectively prevented. The liquid packaging can is mainly used for the package of various liquid foods.

Description

The flexible package punch jar

Technical field

The utility model relates to a kind of packing jar, particularly a kind of packing jar that seals contain fluid.

Background technology

The liquid dairy products packing jar that generally uses now all is the hexahedral shape that the paper compound material is made generally, perhaps adopt herringbone structure to seal at the hexahedral top that the paper compound material is made, in order to prevent that germ from entering in the packing jar, generally all uses the paper compound material that has aluminium foil layer to make and pack jar.But because the packing jar of hexahedral shape is to form by the paper compound material is folded, paper compound material at hexahedral each drift angle place will produce distortion like this, and this distortion is easy to make the aluminium foil layer in the paper compound material to form gauffer, and then make aluminium foil layer some small crackles can occur, germ just is easy to enter in the packing jar after this crackle occurring, and then has polluted the liquid in the packing jar.

The utility model content

For overcoming the defective of existing packing jar, the purpose of this utility model is to provide a kind of and prevents that the flexible package punch jar of crackle from appearring in the aluminium foil layer in the paper compound material.

For achieving the above object, the utility model adopts following technical scheme: this flexible package punch jar comprises the packing jar body that the paper compound material that has aluminium foil layer is made, and described packing jar body is cylindrical or truncated cone-shaped.

Packing jar with respect to hexahedron of the prior art, because the described flexible package punch jar of technique scheme has adopted the packing jar body of cylindrical or truncated cone-shaped, make whole liquid packing jar not have drift angle like this, and the inner part with the liquid direct contact of flexible package punch jar does not all have distortion, aluminium foil layer in the assurance paper compound material can not crack, and can prevent more effectively that germ from entering the liquid in the packing jar pollution packing jar.

Fig. 2 is the partial enlarged drawing in the utility model flexible package punch tank shown in Figure 1 cross section;

Fig. 3 is the partial enlarged drawing of the utility model flexible package punch jar cover opening part shown in Figure 1;

Fig. 4 is the partial enlarged drawing at the utility model flexible package punch jar side seal shown in Figure 1 place.

The specific embodiment

The utility model provides a kind of flexible package punch jar that makes aluminium foil layer in the paper compound material crackle can not occur.Below in conjunction with accompanying drawing the utility model flexible package punch jar is described in detail.

This flexible package punch jar comprises the packing jar body that the paper compound material that has aluminium foil layer is made, and described packing jar body is cylindrical or truncated cone-shaped, by forming in cover, cylindrical shell and a jar end.The specific embodiment of flexible package punch jar shown in Figure 1, the flexible package punch jar in the present embodiment is cylindrical.Make whole liquid packing jar not have drift angle like this, and the inner part with the liquid direct contact of flexible package punch jar all not have distortion, the aluminium foil layer in the assurance paper compound material can not crack; Here use the flexible package punch jar of truncated cone-shaped also can reach same effect.

As further improvement of the present utility model, on the cover 2 of flexible package punch jar, be provided with opening 3, and opening 3 back seaies are provided with easy-open lid, as shown in Figure 1, this easy-open lid can be selected according to the actual needs of cover, as the common easy-open lid that has draw ring (easy-open lid used) as aluminium ring pull end, the easy-open lid that tin-plate is made (as the used easy-open lid on the canned mixed congee) etc.

As further improvement of the present utility model, the concrete structure of the utility model flexible package punch jar easy-open lid as shown in Figure 3, opening 3 places are provided with the diaphragm seal 13 suitable with opening 3, be coated with the aluminium foil 1 of band tearing portion 14 on diaphragm seal 13, described sealing film 13 is affixed with aluminium foil 1 pressing.Opening 3 seal process in the present embodiment are as follows: spray out diaphragm seal 13 at opening part earlier, and after being heated to diaphragm seal 13 to a certain degree, make that diaphragm seal 13 is dissolved, the diaphragm seal after dissolving has viscosity, will press together with the aluminium foil 1 and the diaphragm seal 13 of tearing portion 14 then.Can simultaneously the diaphragm seal on the opening 3 13 be torn by tearing aluminium foil 1 off, the user can insert suction pipe, also liquid can be poured in other containers by opening 3.The shape of this flexible package punch jar cover upper shed 3 can also can adapt to the speed that suction pipe can satisfy pouring liquid again in order to make opening 3 for being clipped the olive shape of an end for circular, oval, the longest string of opening 3 can be able to be set at 20 millimeters.

Can preserve liquid (as sour milk, coconut milk etc.) for a long time in order to make the packing jar, the used material of flexible package punch jar of the present utility model is the paper compound material, as shown in Figure 2, this paper compound material is a multiple-structure, is followed successively by high-molecular polythene (PE) layer 6, printed layers 7, ply of board 8, PE layer 9, aluminium foil layer 10, PE layer 11 by the packing jar outside to a packing jar inboard.Because aluminium foil has heat-proof quality preferably, the PE layer has leak resistance preferably, have good leakproof, heat-proof quality so use this paper compound material to make this flexible package punch jar, the shelf-life that is packaged in its in-to-in liquid product can reach 6 months to 12 months.

In order further to avoid polluting packing jar interior liquid, the shell portion of cylindrical liquid packing jar of the present utility model has also been done following improvement: as shown in Figure 4, before, lap seal curling at rectangular paper plastic composite material dual-side circularizes, be positioned at an axial side of packing jar inboard rectangle or fan annular material after at first will sealing, form revers turn part 15 to the crooked inflection of packing jar lateral direction, relative another side 16 of this rectangle or fan annular material is overlapped on this revers turn part 15 after the sealing.This structure makes all packaged jar of inboard PE layer of the paper compound material that contacts with liquid wrap up, make rectangle material a side 15 burr can with the packing jar in liquid not contact, avoid polluting packing jar interior liquid, also can guarantee the better seal effect.The structure of the side camber inflection of this paper compound material can be used for the flexible package punch jar of truncated cone-shaped too.

The utility model flexible package punch jar is mainly used in the packing of various liquid products, for example: liquid dairy products, non-carbonated beverage, drinks, liquid kitchen seasoning matter and various aqueous Chinese patent drug.
