Abstract

The present invention relates to a method for packing products, which completes folding packing through disposable operation, particularly to a method for packing foods, such as chocolate blocks, chocolate strips or similar articles. A seal thin aluminium sheet packing material with a thermal insulation function is used in the method. A product is put in an asymmetric tubular packing material, and in this way, one edge of the thin aluminium sheet packing material bulges and extends above another edge of the thin sheet to form a cover cap which can be folded downwards. The longitudinal seal of a tubular body is completed by sealing another edge of the thin sheet packing material to the bottom of the cover cap, wherein two lateral flangings are formed; the two lateral flangings are folded downwards so as to be tightly attached on the bottom surface of the product, and then, the cover cap is folded downwards to the bottom surface of the product so as to cover the two lateral flangings.

Description

Packing method and the packing that obtains in this way

What the present invention relates to is a kind of method of packaging product, particularly to the packing of food such as chocolate bar, chocolate bar or ware, has wherein used a kind of packing of heat-insulating and sealing aluminum slice.

The present invention relates to the packing that adopts this method to obtain too.

The common packing of chocolate bar is that use is a kind of in first procedure, for example the composite wafer packing have the layer of aluminum made membrane in this thin slice, and it is heat-insulating and sealing heat-insulating and sealing not perhaps perhaps, and adopt and a kind ofly be considered to suitable mechanical device with its folding packing, as what known; Fasten again in second operation work then that a silk ribbon attached to an official seal or a medal is subjected to or the paper tape of lettering, this packing method has become routine, and continues to be adopted on a large scale.But in any case, it need provide the equipment of at least two kinds of Different Package materials of energy folding.In addition, this packing may not meet the standard that is without prejudice.

Now developed the packaging machine of disposable operation, one or several packing while folding in a folding case has been got up.But this packing is blowing-by but also fragile not only.

Therefore, current have only the machine of twice property operation can reach the purpose that seals and food is without prejudice.

But this class machine has also brought extremely heavy and expensive deficiency naturally.

In order to reduce the above-mentioned shortcoming of mentioning, the present invention proposes by disposable operation and finish the folding packing, the advantage that outward appearance so not only was provided but also has kept its conventional type folding to pack.

This target is that the method according to this invention realizes, it is characterized in that product is placed among the packing of an asymmetric tubulose, the top on another limit of thin slice is just protruded and is reached on these thin slice packing limit like this, forms a folded down front cover lid; Wherein to seal longitudinally be that finish the bottom that another limits of wearing or featuring stage armour thin slice packing is sealed to this front cover lid to tubular body; Wherein formed the flanging of two sides again, these two downward foldings of side flanging are close on the bottom surface of product, and wherein again front cover is covered downward folding to the bottom surface of this product so that cover the flanging of both sides.

Explanation and accompanying drawing with reference to a better embodiment can be understood the present invention better.

Fig. 1 provides the transparent view of the F/s of the method according to this invention, and product is placed among the packing of a tubular body in this course.

Fig. 2 provides the view same with Fig. 1, but explanation is the process afterwards of the method according to this invention.

Fig. 3 provide front cover lid folding process and;

Fig. 4 provides the transparent view of the method according to this invention packaged products.

Referring to Fig. 1, product comprises, chocolate 10 for example, thin slice 11 by the packing of a heat-insulating and sealing aluminium encases, thereby be coated with for example poly heat bonding overplate of one deck above the thin slice, formed a tubular body around the product, and adopted the method on two vertical limits of placing thin slice 11 as shown in Figure 1 asymmetricly, limit 12 has been sealed in a front cover covers on the inside face of 13 bottoms.

As shown in Figure 2, and then the flanging 14 of both sides and 15 along forming in the progradation of arrow A and B direction.This technology is well-known, no longer does detailed description at this.The flanging of these both sides is in their form and sealed before folding downwards.

When the

flanging

14 and 15 of these both sides is folded down the bottom surface 16 that is close to product fully, front cover lid 13, as shown in Figure 3, downward in the direction of arrow C folding is to obtain a packaging product as described in Figure 4.Front cover lid 13 may be at several somes back seaies, perhaps may bar 17 along the line or at least along the part gummed of this line.

This method makes a packing can have the outward appearance of conventional packing, and the flanging of both sides is not obvious owing to being covered by the front cover lid.

For this purpose, the width of front cover lid preferably can be wide to the whole bottom surface 16 that is enough to almost cover product.

Claims

1, a kind of method of packaging product, particularly to food, chocolate bar for example, the method of the packing of chocolate bar or same article, wherein use a kind of packing that contain the tubular sheeting of multilayer insulation leakproofing material, it is characterized by this product (10) is placed in the tubular body of asymmetric this packing, the top on another limit of thin slice is just protruded and is reached on these thin slice packing limit like this, form a folded down front cover lid (13), wherein to seal longitudinally be that realize the bottom that another limit (12) sealing of wearing or featuring stage armour thin slice (11) clings to front cover lid (13) to tubular body; Wherein, two side flangings (14,15) have been formed again, these two downward foldings of side flanging are close to the bottom surface (16) of product (10), and the more downward folding of front cover lid (13) are gone up so that cover in the flanging (14,15) of both sides to this bottom surface (16) thereafter.

2, in accordance with the method for claim 1, it is characterized in that front cover lid (13) along lines parallel with its edge (17), the bottom surface (16) of being close to product (10) is sealed to small part.

3, in accordance with the method for claim 2, the width that it is characterized in that this front cover lid (13) in fact equates with the width of the bottom surface (16) of product (10).

4, described according to claim 1 by packing that this method obtained, be to adopt a kind of method of mono-packing to obtain, this mono-packing comprise the tubular sheeting of a heat-insulating and sealing aluminium, it is characterized in that: it comprises two side flangings, these two side flangings are all covered in by a front cover lid, and the length of front cover lid equates with the width of product bottom surface substantially.
