Abstract

A method is provided in which two or more products are packaged together by wrapping a wrapper of, preferably, a heat-shrinkable plastic sheet material around them. The wrapper is applied so that its opposite edges either overlap and bond together by a contact adhesive, or both bond to one of the products. Optionally, the wrapper is of a heat-shrinkable plastic material, in which case heat may then be applied so as to shrink the wrapper so that the contained products are more firmly held together. It is then an easy matter for the consumer to remove the wrapper, by peeling apart the areas which are held by the contact adhesive. Instead of being positioned side-by-side, the products may be stacked one-on-top-of-the-other, and the wrapper applied around the two products where they meet.

Description

Sleeved package method

The present invention relates to packing method, relate in particular to the lasso packing articles made from plastic material.

The consumption goods are usually sold with a package, and the lasso of often using a thermal contraction during packing a pair of packing of product together.Lasso is that the edge of its opposite end is pasted together by a slice or prefabricated the forming of common hyaline membrane, uses the handlebar grips cover snare again on paired goods, after this heats to shrink lasso, make goods by lasso tightly around.The general goods of selling by this way have cosmetics and treatment etc., but are not limited to cosmetics or treatment.

For aforesaid packing articles, the customer for them separately so that use and will remove lasso, but this thing of difficulty often.

We have designed a kind ofly two or more goods method packaging together now, and this packing method can make the customer easily all goods be separated.

The invention provides a kind of two or more goods method packaging together, this method comprises the steps: to provide a kind of plastic sheet material one or more surf zones that make, on it to have the packaging film of contact adhesive agent, the plastic sheet material can be selected heat-shrinkable, then packaging film being treated goods packaging together holds, make two relative edge's edge of packaging film overlap and be pasted together by the contact adhesive agent that applies on it, or paste on one of them goods, then can apply heat with shrink wrap.

Because film only is to be touched adhesive agent to remain on a certain position, so as long as the customer peels off and is touched the fixing zone of adhesive agent and just can removes packaging film easily.

Two or more goods are arranged side by side, and packaging film is around these goods.Perhaps, one in goods are superimposed upon above another, packaging film then be centered around each to adjacent article meet the place the position on.

For all goods that are arranged side by side, the preferably heat-shrinkable material of packaging film, and after packaging film surrounds on the goods, packaging film is applied heat, so that shrink wrap makes this packaging film be firmly held in all goods together more.For all goods that are superimposed upon on another top, I always not need to find the heat shrink packaging film.

For example, can be applied to a continuous or discontinuous contact adhesive agent on one edge of packaging film, in case and arrange packaging film surround goods around, when its edge overlaps mutually, just two relative edge's edge of packaging film can be pasted together.

For all goods that are arranged side by side, packaging film can not exclusively hold all goods: a continuous or discontinuous contact adhesive agent is applied to the relative two edges of goods, in case and arrange packaging film part during through two (or more) together goods, the contact adhesive agent along around be pasted on one of described goods on the position that separates.

Preferably also apply the contact adhesive agent on the inside face of packaging film, when holding all goods with convenient packaging film, the contact adhesive agent pastes (or on packing material of those goods) on the goods.In this way, all goods just can be firmly held in together more, thereby have avoided all goods trouble of slippage or separation each other.

Packing method of the present invention helps automated package.Goods to be held are preferably put together earlier and along with conveyer advances, and simultaneously from next section of roll film material cutting packaging film, deliver to the bench board on the desired zone that a contact adhesive agent is applied to packaging film, and then preceding and then hold all goods.But weblike material also can apply adhesive agent in advance on desired zone before it is rolled.When packaging film wound on the semifinished piece, the goods that held can readvance and one apply on the bench board of heat with shrink wrap.

Describe embodiments of the invention below by way of example and in conjunction with the accompanying drawings, the present invention is not limited to these embodiment, wherein:

Fig. 1 is a scheme drawing, and it illustrates a pair of goods that will hold side by side and will wrap this to the packaging film on the goods;

Fig. 2 is a similar view, and it shows packaging film and has wrapped in situation on all goods;

Fig. 3 is a similar view, and it shows packaged good all goods;

Fig. 4 illustrate held side by side by another kind of packaging film another to goods;

Fig. 5 is a scheme drawing, and it illustrates goods for the treatment of the stack that holds;

Fig. 6 illustrate one will be used for wrapping in packaging film on the paired goods shown in Figure 5;

Fig. 7 is a view, and it illustrates a packaging film that wraps on the paired goods shown in Figure 5; And

Fig. 8 is similar view, and it shows goods shown in Figure 5 by the situation after holding.

Consult Fig. 1.A pair of

goods

10,12 shown in the figure, this will be wrapped up side by side to goods, sells together then.In an example shown, these two goods have cylindrical shape or tubular container or distributing box, and their height is all identical with diameter, but the present invention can similarly be applied to the goods of other shape, and wherein the size of two goods and/or shape can differ from one another.According to the present invention, with suitable orientation double-

type goods

10,12 are combined, and advanced along a conveyer.Simultaneously, from next section of volume plastic sheet film cutting packaging film 20, and the contact adhesive agent with the form of bar 21 be applied to packaging film 20 edges near.As shown in Figure 2, packaging film 20 advances, and comes paired

goods

10,12, surrounds into then goods are packed, and to the last two relative edge's edge of (as shown in Figure 3) packaging film overlap and bond together by contact bonding strip 21.Preferably, bonding strip 21 leaves a bit of distance in end of packaging film, so that stay a tongue limit sheet 24.Preferably, packaging film adopts heat-shrinkable material, and like this, the paired goods of wrapping up enter a bench board, apply heat with shrinkage sleeve at this bench board, the result, and these two goods are firmly held in together more by this sleeve.Said process is to be applicable to that by one the machine of this purposes carries out automatically, has omitted the accompanying drawing of these each parts of machine at this.

The customer who buys the goods of packing in pairs peels away the relative two edges of packaging film just and can separate goods easily along contact bonding strip 21 by uvula limit sheet 24 left after packaging film 20 thermal contractions.

Also can on packaging film 20, increase the contact bonding strip in addition, the inside face of packaging film is bonded on one or two goods 10,12.For example, can apply a contact bonding strip 22, make it can contact goods 10 along the centre of packaging film.Can apply a contact bonding strip 23 again near packaging film one edge, with the lap-joint of two relative edge's edge of packaging film or near lap-joint contact goods 12.

Contact bonding strip

22,23 is bonded to (or being bonded in the external packing that is pre-applied on these goods) on the

goods

10,12 to the inside face of packaging film, makes paired goods be securely held in together in final packaging.But the customer still can strip down packaging film easily from described goods.

As shown in Figures 1 to 3, packaging film needn't extend to the whole height of packaged

goods

10,12, and that is because highly lower packaging film can keep together goods equally securely.

As shown in Figure 4, packaging film needn't hold two goods fully, and promptly two relative edge's edge of packaging film needn't overlap.In example shown in Figure 4, goods 30 have a columnar container or a distributing box, and another goods 32 have the carton that a glass paper holds.One packaging film 40 be packaged in goods 30 around, its relative two edges (existing contact bonding strip be applied thereto) is overlapped on the edge of relative both sides of carton.Packaging film 40 preferably has heat-shrinkable, so that goods keep together more firmly, still, because packaging film only contacts with a very little area on the Wrapped in Cellophane box, the Wrapped in Cellophane box can significantly not be out of shape.The customer still can take off this packaging film 40 easily by carton 32 is peeled off at the edge of packaging film 40.

Replace continuous or discontinuous vertical contact bonding strip is set, also horizontally extending bonding strip can be set on the packaging film, or both have both at the same time, and this horizontal bonding strip can continuously also can be discontinuous.

Fig. 5 illustrates the individual one to one

goods

42,44 that are superimposed upon on another top, sells together after they are to be packaged.In an example shown, two goods all have columnar or tubular container, and the height shown in the figure is also identical with diameter, still, the present invention can be applicable to the goods of other shape too, and wherein the size of two goods and/or shape can be differing from each other.For the goods of arranging as Fig. 5 can be linked together according to the present invention, one of them goods 42 is placed on the top of another goods 44, and two

goods

42,44 are advanced along a conveyer.Simultaneously, next section of cutting packaging film 46 (see figure 6)s from a volume plastic sheet film, the contact adhesive agent 52 of a strip is applied to across ground packaging film an end near.Packaging film 46 also advances on conveyer across ground, make paired

goods

42,44 contact with packaging film in the central, the both ends of packaging film hold paired goods (see figure 7) then, and up to finally, two opposite end portions of packaging film overlap joint also bonds together by contact bonding strip 52.Preferably, bonding strip 52 leaves a bit of distance in end of packaging film, so that stay a tongue limit sheet 56.Select heat-shrinkable material as packaging film, like this, the paired goods of wrapping up enter a bench board, apply heat with shrinkage sleeve at this bench board, the result, and these two goods are firmly held in together more by this sleeve.The

contact bonding strip

48,50 of length direction preferably is provided, the inside face of packaging film is bonded to (or being bonded on any overpack that is applied in advance on these goods) on the

goods

42,44, make paired goods in final packaging, be securely held in together.But the customer still can strip down packaging film easily from described goods.Said process is to be applicable to that by one the machine of this purposes carries out automatically, has omitted the accompanying drawing of these each parts of machine at this.

The customer who buys a kind of like this goods of paired packing passes through uvula limit sheet 56 left after packaging film 46 thermal contractions, and edge contact bonding strip 52 is peeled away the relative two edges of packaging film and can be separated goods easily.

Shown in Fig. 7 and 8, packaging film only extends the sub-fraction of the bottom-to-top-height of goods to be packaged 42,44, but still can be firmly held in goods together.

Replace continuous or discontinuous level

contact bonding strip

48,50 is set, also can the vertical extent bar be set on packaging film, or both have both at the same time, and this vertical bonding strip can continuously also can be discontinuous along the diverse location of packaging film length.

With the different a kind of process of above-mentioned packaging process in, packaging film is prefabricated, has the contact adhesive agent of required area on this prefabricated packaging film.For example, all packaging films can be arranged on the volume base stock, and the contact adhesive agent by certain area is bonded in these packaging films on the base stock, then packaging film are peeled off its base stock and wrap up in around goods to be packaged, as mentioned above.

Should give and be understood that if desired, packaging film can be printed in advance.And if desired, packaging film is well cutting in advance, or cuts into reservation shape.
