Description

Description: FIELD OF THE INVENTION The present invention relates to a pillow package and a method for producing the same, and in particular, a medicine package containing therein a drug such as a deoxygenating agent, a decarbonating gas agent, or a hygroscopic agent. And a method of manufacturing the same.

[Conventional technology]

Conventionally, as a package made of a film, a pillow package having seal portions formed at both ends and a body portion has been widely used. As a device for manufacturing the pillow package, a film unwound from a roll is used. A vertical cylindrical shape is bent while being bent by the sailor portion, and the vertical film edges overlapped with each other are sealed, and the cylindrical film is horizontally sealed. A vertical pillow wrapping machine is used in which the contents are filled through an inner guide inserted into the sailor section, and then the film on the filling section is horizontally sealed.

Depending on the contents, such a pillow package is sealed with a chemical such as a deoxidizer, a decarbonizer, or a moisture absorbent. These drugs are usually used in the form of a medicine package wrapped with a breathable film or the like, and when the contents are filled by a vertical pillow wrapping machine, they are put into the pillow package together with the contents.

[Problems to be solved by the invention]

However, if the medicine package is simply put in the pillow package, there is a problem that the medicine package moves in the pillow package and also goes out when the contents are taken out.

As a solution to this, as shown in FIG. 10, a medicine package 1 is attached to a long tape 2 at an appropriate interval, and the tape 2 is attached to a vertical pillow packaging machine in the direction of arrow A. The tape 2 is simultaneously sealed together with the contents (not shown) in the cylindrical film 3 while moving the film 3 and sealing the film 3 in the horizontal direction to form the sealing portion 3a. It has been proposed to fix it.

However, in this method, it is necessary to attach the medicine package 1 to the tape 2 in advance, which causes an increase in cost. It is necessary to draw the tape 2 into the film 3 with the movement of the film 3 in the direction of arrow A.
Generally, since the tape is easily stretched, there is a problem that the running speed of the tape is limited, the bag making speed is limited, and the production amount is reduced.

The present invention has been made in view of such a problem, and an object of the present invention is to provide a pillow package that can fix a medicine package containing a medicine without using a tape 2 and a method for manufacturing the same.

[Means for solving the problem]

The present invention relates to a pillow package having seal portions formed at both ends and a body portion, wraps a gas-permeable packaging material so that side edges on both sides are shifted, and stores a medicine between overlapping portions. A medicine package which seals the periphery and has a side edge extending outward from one side edge and having a heat-sealable mounting portion is housed inside the pillow package, and the medicine package is pillowed. The pillow package, which is spot-fixed to the film forming the package and the package is sealed by inserting the mounting portion of the medicine package into the seal portion, and the film unwound from the winding device are bent while being bent by the sailor portion. The vertical film is vertically sealed, and the vertical film edges overlapped with each other are sealed, and the cylindrical film is horizontally sealed. The sailor is placed in the cylindrical film above the horizontal sealing portion. Filled with contents through the guide among inserted in portion, then, in the manufacturing method of the pillow package for sealing the film over the filled portion in a horizontal direction,
On the film before being sent to the sailor unit, a gas permeable packaging material is folded back so that the side edges on both sides are shifted, and the medicine is stored between the overlapping parts, and the periphery is sealed and A medicine package having a side edge extending outward from one side edge and having a heat sealable mounting portion is supplied so that the mounting portion is located at a sealing portion of the film. The method of manufacturing a pillow package is characterized in that the pillow is spot-stopped on the film, and the sealing portion is sealed simultaneously with the mounting portion of the medicine package sandwiched between the films.

[Action]

In the pillow package having the above structure, since the mounting portion at one end of the medicine package containing the medicine is sealed by being sandwiched between the films of the seal portion of the pillow package, the medicine package may move in the pillow package. And there is no removal with the contents. Moreover, it is not necessary to use an extra tape or the like for fixing the medicine package. Furthermore, since the mounting portion formed on the medicine package is composed of only one packaging material, the thickness of the sealing portion does not become too large when it is inserted into the sealing portion of the pillow package, so that it is good. The seal can be easily made and the appearance is not deteriorated.

In the method of manufacturing a pillow package having the above configuration, the medicine package is supplied to the film before being sent to the sailor unit, and one point is stopped so that the medicine package travels with the film and is sent to the sailor unit. In this sailor section, the film is bent and formed into a cylindrical shape, but since the medicine package is only spot-fixed to the film at one point, it is impossible for the medicine package to bend when the film is bent in the sailor section. It passes through the sailor without any difficulty and enters the inside of the film. Thereafter, the tubular film is sealed in the vertical and horizontal directions to form a pillow package, and at the same time, the mounting portion at one end of the medicine package is sandwiched between the films and fixed. Therefore, there is no need to provide an extra sealing step for fixing the medicine package.

It is a horizontal sealing device provided. The horizontal sealing device 16 is configured to be able to repeat a box motion as indicated by arrows a, b, and c, and to seal the film 6 and allow the film 6 to be intermittently drawn from the winding 12 and run. Things. Reference numeral 17 denotes a feed assist belt, and reference numeral 18 denotes a pipe-shaped inner guide for inserting contents into a cylindrical film. These structures are the same as those of the conventional vertical pillow packaging machine.

In this vertical pillow packaging machine, the medicine package 8 is supplied at the position P onto the film 6 before being sent to the sailor unit 14,
An apparatus (not shown) for stopping the spot is provided. As shown in FIGS. 6 and 7, the apparatus includes a winding 21 for unwinding a medicine band 20 forming a medicine package 8 in a band shape;
A nip roller 22 that intermittently feeds the medicine package 20 by one of the medicine packages 8, a cutter 23 that cuts the medicine package 20 to separate one medicine package 8, and a cut medicine package 8 on the film 6. It has a shooter 24 for guiding, a shutter 25 for regulating the position of the medicine package 8, a spot stopper 26 for spot-fixing the medicine package 8 located on the film 6 to the film 6 at one point, and the like. The medicine bandage 20 is attached to one side edge as shown in FIG.
The medicine package 8 is connected so that 9b is located. Therefore, by cutting the position indicated by the two-dot chain line, one medicine package 8 can be cut off, When dropped onto the chute 24 in FIG. 6, the medicine package 8 travels along the chute 24 with the mounting portion 9b lying on the chute 24 as shown in FIG. . The arrangement of the shooter 24 is determined such that the mounting portion 9b of the medicine package 8 supplied onto the film 6 by the shooter 24 is near one side edge of the film 6 and parallel to the side edge.

In FIG. 5, the outer surface of the inner guide 18 has a film 6
At the portion where medicine package 8 spot-stopped passes, medicine package 8
Recess 18a is formed to avoid interference with

Next, a method of manufacturing a pillow package using the above-described apparatus will be described. In FIG. 5, as in the conventional vertical pillow wrapping machine, the film 6 includes a horizontal sealing device 16 and a feeding auxiliary belt 17.

Bends the film 6 into a vertical cylinder, a vertical sealing device 15 seals the overlapped vertical film edges, and a horizontal sealing device 16 seals the cylindrical film in the horizontal direction. Cut the middle of the seal. A predetermined amount of content is filled through the inner guide 18 into the cylindrical film on the portion sealed by the horizontal sealing device 16. After filling the contents, the horizontal sealing device 16
Is moved by one pitch of the pillow package 5 in the direction of arrow a with the film sandwiched therebetween, and the film 6 is moved downward, and then the horizontal sealing device 16 moves as shown by arrows b and c. Seal the top of the filled film section and cut off the top section. By repeating the above operation, the pillow package 5 is produced one after another.

In the above steps, while the film 6 is stopped, as shown in FIG. 6, one medicine package 8 at the lower end of the medicine bandage 20 is cut by the cutter 23 and supplied to the vicinity of the end of the film 6 by the shooter 24. Is done. At this time, the shutter 25 is at a position for stopping the medicine package 8 as shown in the figure, and stops the medicine package 8 sliding on the shooter 24 at a predetermined position on the film 6. Thus, the medicine package 8 is positioned at a position where the mounting portion 9b at one end is near the edge of the film 6, that is, at a position where the vertical seal portion 6b is formed. Next, the spot stop device 26 is operated to spot stop one point of the medicine package 8 on the film 6 by heat sealing. At this time, the position for stopping the spot (the position of the spot stopping portion 9c in FIG. 1) is not particularly limited, but it is preferable to be as close to the center of the medicine package 8 as possible. The center of the portion 9b and the center side of the medicine package. Thereafter, before the film 6 travels, the shutter 25 is opened by a drive device (not shown), and the medicine package 8 is sent downstream together with the film 6. Instead of opening and closing the shutter 25 with a drive device, the shutter 25 may be normally set to a closed position by a spring and pushed and opened by a medicine package spot-fixed to the film when the film runs.

In FIG. 5, the film 6 on which the medicine package 8 has been spot-stopped is intermittently fed as described above, and is bent at the sailor section 14 to form a tubular shape. Because it is only stopped on the spot,
The medicine package 8 itself does not need to be bent into a shape along the bent surface of the sailor portion 14, but smoothly passes through the bending point of the sailor portion 14 and is put inside the cylindrical shape of the film. At this time, there is a recess 18a outside the inner guide 18, so that passage of the medicine package 8 is not hindered. As soon as the medicine package 8 passes the bending point of the sailor section 14, the mounting portion 9b of the medicine package 8 is sandwiched between both edges of the film 6, and moves between the vertical sealing devices 15,
This vertical sealing device 15 seals between the overlapping edges of the film 6, and at the same time, the mounting portion 9b is also joined to the film.
As described above, since the medicine package 8 is adhered by the vertical sealing device 15 immediately after passing through the sailor section 14, there is no problem at all without stopping the spot at one point. As described above, the first
As shown in the figure, a pillow package 5 containing the medicine package 8 sealed in the vertical seal portion 6b is produced.

In the above embodiment, the shooter 24 is used to supply the medicine package 8 onto the film 6.
The device for supplying the ink to the upper side is not limited to this, and can be changed as appropriate. Further, the spot stop of the medicine package 8 on the film 6 is not limited to the heat sealing, and may be performed by another method, for example, a method using a hot melt adhesive.

Further, in the above embodiment, the medicine package 8 is adhered to the vertical seal portion 6b of the pillow package 5 as shown in FIG. 1, but instead, the medicine package 8 is horizontally sealed as shown in FIG. It may be configured to be inserted into the portion 6a. In this case, the horizontal seal 6a
It is preferable that the width of the portion is large so that the portion holding the medicine package 8 is large. When the medicine package 8 is sandwiched between the vertical seal portions 6b as in the embodiment of FIG. 1, the allowable range of the mounting position of the medicine package 8 with respect to the film 6 can be increased in the film moving direction, so that the production management can be reduced. The advantage that it becomes easy is obtained.

〔The invention's effect〕

As described above, in the pillow package of the present invention, the attachment portion at one end of the medicine package containing the medicine is sealed by being sandwiched between the films of the seal portion of the pillow package, so that the medicine package has the pillow package. It does not move in the body and is not taken out with the contents. Furthermore, since the mounting part of the medicine package is composed of only one packaging material, it is inserted into the seal part of the pillow package. In such a case, the thickness of the seal portion does not become too large, good sealing is possible, and the appearance is not deteriorated.

In the method of manufacturing a pillow package of the present invention, the medicine package is supplied to the film before being sent to the sailor unit, and the medicine package is fed into the pillow package by spot-stopping one point. In addition, there is no need for the process of bonding the medicine package to the tape, and the running speed of the film can be increased as compared with the case where tape is used, and the pillow package with the medicine package fixed can be produced with high productivity. This has the effect.
