Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging bag in which waste paper for chewing gum is integrated and a method for producing the same.

[0002]

2. Description of the Related Art Chewing gum (hereinafter referred to as "gum"), which is a kind of confectionery, has sticky bites (hereinafter referred to as "slag") remaining after being chewed. In order to adhere, it is generally wrapped in paper (hereinafter referred to as discarded paper) or the like and discarded. When the discarded paper is sold in the form of a gum plate, as shown in FIG. 7, the sheet gum G 'is wrapped one by one with the interior paper 10 and the wrapping paper with the design is wrapped around the outside. 11, the interior paper 10 and the wrapping paper 11 with picture are both large enough to wrap the slag, and generally, any one of these is used as a discarded paper. . Further, in packaging relatively large granular gums, individual granular gums are wrapped in slightly larger wrapping paper so that the wrapping paper can be used as waste paper. In some cases, the granular gum is stored in a plastic molding container. In this case, as shown in FIG. In some cases, a sticker is attached, or a discarded paper is separately prepared and stored in a case together with the granular gum of the contents. The plastic case is more expensive as a gum packaging material than packaging with a laminate film, paperboard or the like. However, in the case of products in which relatively small gums are stored in a container in a naked state without individually wrapping them, many containers for the small gums are provided with a dispensing mechanism. When taking out an object, the object is taken out from the outlet. In this case, it is conceivable to put several discarded papers in the container mixed with the gum as the content. However, although this method is simple, counting the number of papers and enclosing them in a container is unexpectedly troublesome and inefficient. There is also a problem that it is difficult to take out the discarded paper because it is mixed with gum. Further, when the bellows fold label 21 is adhered to the outer surface of the granular gum case, the bellows may extend to the outside of the case as shown in FIG. Further, although this method has an advantage that the sticking of the label is easy to automate, it costs a lot as a cost for an adhesive processing (seal processing) as the label. In the past, many containers that used to store such naked gums were unavoidable, so it was necessary to prepare another piece of paper, such as dust paper, when discarding the residue after the bite was finished. . Also, if you do not wrap it in paper and throw it away on the street or on the platform of the station, it will adhere to the pedestrian's shoe sole,
It often gave me unpleasant thoughts. Although this case has the problem of morality, these problems can be resolved by containing the discarded paper in the gum container, so a packaging method that sets the discarded paper in the container easily and without damaging the appearance has been developed. Was desired.

[0003]

SUMMARY OF THE INVENTION In a small-gum package, an inexpensive packaging material is used to integrate the waste paper when throwing away the bite after chewing, so that the packaging process is not hindered. Provided is a gum packaging bag which does not impair the appearance of a package and a method for producing the same.

[0004]

The present invention is a packaging bag in which gum is packed with a packaging material, wherein a filling portion filled with gum and an empty bag portion not filled with gum are formed continuously. The filling bag forming a tetrahedron, wherein the filling portion forms a tetrahedron, and the packing material is formed into a tubular shape and the gum is sealed in the longitudinal direction. A method for producing a packaging bag for filling, wherein at least one of the above-mentioned gums is filled, and a gum-filled portion and an empty-bag portion not filled with gum are cut into one packaging unit to form a gum package. It is a manufacturing method of a bag.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The gum packaging bag of the present invention is embodied in a pillow packaging bag or a modified bag thereof which is performed by a packaging system generally called a vertical pillow packaging machine. The pillow packaging is performed as follows. That is, the packaging material unwound from the winding is wound around a tubular body called a former to form the packaging material into a tubular shape, the bottom of the tubular body is heat-sealed, and the contents are filled from inside the tube of the tubular body. The packing material is moved to the lower part together with sealing the top part (at this time, simultaneously sealing the bottom part of the next bag), and the top part of the filled part is cut. The gum packaging bag of the present invention is constructed by using a combination of the filling portion of the contents and the empty bag portion as a packaging unit. FIG. 1 is a front view (a), a perspective view (b), and a perspective view (c) of a state in which a discarded paper is folded, showing an embodiment of the gum packaging bag of the present invention. FIG. It is a development view of an example. FIG. 3 is a perspective view (a) showing another embodiment (tetrahedral shape) of the gum packaging bag of the present invention, and a perspective view (b) showing an example in which the waste paper portion is flattened. FIG. 4 shows FIG.
3A is a perspective view showing a continuous bag state in a tetrahedron packaging example of the embodiment shown in FIG. 3A, and FIG. FIG. 5 is a perspective view of a packaging bag showing a specific embodiment of the present invention, and FIG. 6 is a perspective view of a packaging bag showing another specific embodiment of the present invention.

As described above, the present invention is carried out in a vertical pillow type packaging process. Usually, by continuously filling the contents to be filled one by one, an empty bag portion is formed between the filling portion and the filling portion, and the empty bag portion is easily used as waste paper. For this purpose, a weak line such as a perforation is formed. One embodiment of the present invention is possible in a bag in the form of a pillow package as shown in FIG. The gum storage unit 1 includes a gasket seal unit 4 and upper and lower seal units 3a and 3b, and the discarded paper unit 2 does not have the lower seal 3b in principle. This is because the lower seal 3b of the discarded paper portion 2 is not used, so that it is easier to cut out the discarded paper from the weakening line 5. However, when a small extra is attached in product planning for children or the like, the discarded paper of the present invention can be used, and in that case, the discarded paper part 2 may also be provided with the upper and lower seals 3a and 3b. it can. A weakened line 5 such as a perforation is provided in the discarded paper section 2 so that the paper can be cut into a size that is easy to use as discarded paper. The weakening line may be formed by a method using a half cut, a cut tape, or the like in addition to the perforations.

FIG. 1 shows an embodiment of the gum packaging of the present invention, in which an empty bag portion 2 is continuously provided at a top portion or a lower portion of a gum storage portion 1. In the present invention, the empty bag portion is used as the discarded paper portion 2. As shown in FIG. 2, a weakening line 5 is provided inside the seal portion of the discarded paper portion so that the gum storage portion and the empty bag portion can be separated and the empty bag portion can be easily used as discarded paper. . As a result, it can be easily cut off by the weakening line, and the obtained cutout forms an area convenient for wrapping and discarding the gum residue after chewing. In the case of FIG. 2, only 2a and 2b can be used as discarded paper, and these may be used as two sheets or as one large discarded sheet. The processing of the weakening line 5 on the packaging material in the present invention may be performed by a separate process before being applied to the packaging machine. However, in the packaging machine, the packaging material is in a flat state before reaching the former section. It is preferred to process at the time of.

In the practice of the present invention, the intended gum packaging bag can be obtained by putting the contents at every other position in the continuous filling at the same time as the formation of the tubular body.
Therefore, as a product, the filling section 1 and the empty bag section 2 are set and cut, and the empty bag section 2 is used as discarded paper. In the empty bag section 2, a weakening line 5 is provided to make it easy to cut out discarded paper. It is possible to perform the filling at every other position by changing the program for charging the filling material into the filling hopper.

The gum packaging bag of the present invention is formed in a tubular shape,
It is a packaging form in which the top and bottom are sealed, and the seal forming the cylinder may be a joint-type seal or an envelope-type seal. Also, the upper and lower seals are alternately
The package may be rotated so as to form a tetrahedron as shown in FIG. As a method, as shown in a conceptual diagram in FIG. 4B, for example, two sets of seal units (31a and 31b) are prepared, and the seals are alternately changed in the A direction and the B direction while changing the angle of the seal by 90 °. This can be realized by sealing the seal. In the obtained packaging bag, a tetrahedral bag as shown in FIG. 4 (a) is connected, and the storage portion 1 and the discarded paper 2 are alternately formed by filling the contents one by one. Will be. The gum packaging bag of the present invention can be obtained by cutting the gum storage unit 1 and the waste paper 2 while keeping them connected. The present invention thus provides:
Also in the formation of the tetrahedron, a gum packaging bag with a waste paper forming portion (empty bag portion) 2 can be formed by forming the gum storage portion 1 and the empty bag portion 2.

[0010] In filling by a packaging machine, a cylindrical body is formed, and the lower part thereof is filled with contents by means of upper and lower seals 3a and 3b, and then the upper and lower seals are again performed. Is disconnected. That is, the upper seal and the lower seal as products are continuously provided as a seal plate of the packaging machine. The upper and lower seals are performed simultaneously, and the packaging material is cut in the middle of the upper and lower seals to form a unit package. In the present invention, since the cutting is performed every other, the space between the filling portion 1 of the contents and the empty bag portion 2 is not cut and is set as a packaging unit of the present invention. The packaging material in the empty bag portion is used as discarded paper. When providing more discarded paper sections, it is possible to provide two or more empty bags for the gum storage section 1. In this case, the filling program may be changed to perform one filling for three pitch feeds. In this manner, it is possible to form an empty bag portion by placing every other or every third or third, etc. by changing the filling program in the filling device, and in the upper and lower seals, Making the outer end of the discarded paper portion unsealed can be easily performed by changing the shape of the seal bar. The content filling portion and the empty bag portion preferably have the same pitch, but are formed into a cylindrical shape in the forming portion of the packaging machine, and the amount of feeding the cylindrical body at the time of filling the content and sealingly sealing. By changing the (length), it is also possible to change the length of the filling portion and the empty bag portion.

The present invention is desirably implemented by an automatic bag making and filling type packaging machine as described above. However, in the case where the filling is performed manually, etc., either the gasket seal or both ends are sealed in advance. Then, a bag cut to a predetermined length is prepared, and the contents are filled by hand from the open ends of the both ends, and then filled in a substantially middle portion of the length of the cylindrical bag. It can also be implemented by hermetically sealing the parts. Although the packaging material from the hermetically sealed portion to the initial open end is a portion used as waste paper, the open end may be sealed,
It may be left open.

Also, in the above-mentioned tetrahedral packaging bag, the bag is made in advance (same as the pillow), and when sealing the intermediate portion after the contents are put in, the sealed end portion is made in advance. A tetrahedral bag can be obtained by sealing at an angle that is perpendicular to the part seal.

The packaging material used for the gum packaging bag of the present invention comprises:
Laminated films made of various materials are desirable. As the base material, a film or thin paper having good dimensional stability and excellent printability and heat resistance is used, and an inner surface layer made of a material having heat sealability is laminated. If necessary, another material may be laminated between the base material and the inner surface layer for the purpose of moisture proofing, light shielding, gas barrier properties and the like. As a substrate, polypropylene, polyester, nylon, cellophane, paper,
A simple substance such as an aluminum foil or a laminate of these materials can be used. Also, as the inner layer,
It can be laminated with a resin or film having heat sealing properties, a coating layer, or the like. Examples of the resin or film having heat sealing properties include low-density polyethylene, polypropylene, ethylene-vinyl acetate copolymer, and ionomer. Further, as the coating layer, an ethylene-vinyl acetate copolymer-based resin, a vinyl chloride-vinyl acetate-based resin, an organic solvent type having an adhesive component such as an acrylic resin, an aqueous emulsion type, an adhesive such as a hot melt type, It can be formed by continuous or partial application.

Next, the weakened line 5 of the discarded paper part in the present invention
Will be described. When the empty bag portion 2 formed as described above is used as discarded paper, it is necessary to cut it out to a size necessary for use as discarded paper. As a method, it is preferable to provide a weakening line 5. . By providing the weakening line 5 in the empty bag portion 5 and cutting off the empty bag portion 2 along the weakening line 5, waste paper can be obtained. The gum requires waste paper each time the waste is thrown away, but in the present invention, the waste paper is cut off when necessary, and the waste paper part to be used next is connected to the filling part of the contents, so that it is dissipated. I will not do it. As a method for forming the weakening line 5, a technique such as a perforation, a half-cut method using a carbon dioxide laser or the like can be used. You may.

In the empty bag section 2, other information can be printed in addition to the explanation of how to use the paper as discarded paper. Along with the empty bag section, the packaging material of the content filling section can also be used as waste paper. If the product is for children, the empty bag 2
Various extras may be enclosed. The empty bag section 2
As shown in FIG. 1 (c), in the vicinity of the gum storing section 1, the sheet is bent and folded on the filling section, and its end is temporarily attached to the filling section with a seal label 6 or the like. It can be made compact as a packaging bag.
