Description

Blister packing machine, method of manufacturing blister pack and blister pack

The present invention relates to a blister pack for containing predetermined contents, and a blister packaging machine for producing the blister pack and a method for producing the blister pack.

The blister pack comprises a container formed with a pocket for containing various contents, and a cover attached to the container to seal the open side of the pocket. The blister pack is manufactured by a blister packer equipped with various means such as pocket forming means for forming the pocket.

By the way, as a kind of a package such as a blister pack, a bag-like filter in which the contents are accommodated and an opening-side outer peripheral part of the bag-like filter is attached to its own opening-side inner peripheral part (sidewall part) And a cover attached to the cup-shaped container so as to close both openings of the bag-shaped filter and the cup-shaped container, and the bag in the inside of the cup-shaped container There is known one in which a chamber (chamber) is formed between the second filter and the cup-shaped container (see, for example, Patent Document 1). This package contains coffee powder (e.g. ground coffee or powder extract) in a bag-like filter, and when used, the tubular injection probe pierces the cover and is placed in the bag-like filter Also, a tubular ejection probe is placed in the chamber through the bottom of the cup-shaped container. Then, when hot water is supplied into the bag-like filter through the injection probe, the coffee is extracted into the chamber through the bag-like filter and is sent out of the chamber through the discharge probe.

Moreover, in the said patent document, the above packages are manufactured through the following processes. That is, the bag-like filter is manufactured by bending or welding the heat-weldable band-like filter material. Next, a bag-shaped filter is disposed inside a cup-shaped container manufactured in advance, and then the opening of the bag-shaped filter is expanded. Thereafter, the opening-side outer periphery of the bag-like filter and the opening-side inner periphery of the cup-shaped container are welded. Finally, after the coffee powder is supplied to the bag-like filter, the cover is used to close the opening of the cup-shaped container or the like to manufacture the package.

12, 13 are overlaid. The cover film 14 is drawn out from the cover film raw film 24 in which the cover film 14 is wound in a roll, and is guided to the receiving roller 28. The cover film 14 is intermittently transported downstream in synchronization with the transport operation of the

respective container films

12 and 13 by a predetermined transport means (not shown).

A sealing device 29 as sealing means is provided downstream of the receiving roller 28. As a result, the sealing device 29 is provided corresponding to the position where the transport paths of the

films

12, 13 and 14 overlap each other. The sealing device 29 closes the openings of the outer pocket portion 2a and the inner pocket portion 3a by the cover film 14 to seal the inside of the

pocket portions

2a and 3a. By passing through the sealing device 29, a strip-like blister film 11 including the

films

12, 13 and 14 can be obtained.

The sealing device 29 is provided with an upper die 29a and a lower die 29b, both of which are separated from each

film

12, 13, 14 by the drive means (not shown), and the approach position for approaching each

film

12, 13, 14. It is movable between the retracted position. The upper mold 29a and the lower mold 29b are disposed in the approach position to sandwich the

films

12, 13 and 14, respectively. Further, at least a portion of the upper mold 29a where the

films

12, 13 and 14 are sandwiched between the lower mold 29b and the lower mold 29b can generate heat by a heater (not shown) or the like. In addition, the sealing process (sealing process) of both the

pocket parts

2a and 3a by the sealing apparatus 29 is demonstrated later.

A punching device 30 is provided downstream of the sealing device 29 as punching means for punching the blister film 11 into one blister pack. A cutting device (not shown) is provided downstream of the punching device 30 for cutting the scrap portion left by the punching. The scrap portion is cut into a predetermined size in the cutting device and stored in a predetermined scrap hopper (not shown).

Further, below the punching device 30, a conveyor 31 is provided for transferring the obtained blister pack 1 to a hopper for a finished product (not shown).

Then, the manufacturing process of the blister pack 1 using the said blister packaging machine 20 is demonstrated. The manufacturing process of the blister pack 1 includes, as shown in FIG. 6, a pocket portion forming process S1, a supplying process S2, a sealing process S3 and a punching process S4.

The pocket portion forming step S1 includes a heating step S11, a holding step S12, an inner pocket portion forming step S13 and an outer pocket portion forming step S14. In heating process S11, the formation range of at least each

pocket part

2a, 3a in the

films

12 and 13 for both containers is heated by the heating apparatus 25 at once.

Next, in the sandwiching step S12, the upper mold 262 and the lower mold 263 are disposed at the approach positions, respectively, and the two

container films

12 and 13 temporarily stopped are sandwiched between the upper mold 262 and the lower mold 263. More specifically, the upper surface of the heating guide 262 b and the lower die 263 sandwiches the portion to be the outer flange portion corresponding portion 12 b and the inner flange portion corresponding portion 13 b of the both

container films

12 and 13. At this time, the plug 262a is disposed at the immersion position. In addition, the plug 262a and the heating guide 262b are in a preheated state.

Next, in the inner pocket portion forming step S13, as shown in FIG. 7, the plug 262a is moved to the protruding position while both the

container films

12 and 13 are held by the heating guide 262b and the lower die 263. As a result, the plug 262a protrudes from the lower surface of the heating guide 262b so as to enter the recess 263a. Then, the two

container films

12 and 13 in a stacked state are pressed by the plug 262a, and the two

container films

12 and 13 are deformed along the tip end face of the plug 262a. As a result, the inner pocket portion 3a and the inner flange portion corresponding portion 13b are formed on the inner container film 13. The inner pocket portion 3a is thermally fixed, and its shape is stably maintained. In addition, a temporary outer pocket portion 2 c having substantially the same shape as the inner pocket portion 3 a is formed on the outer container film 12.

Thereafter, in the outer pocket portion forming step S14, as shown in FIG. 8, with the plug 262a being disposed in the recess 263a and supporting the inner pocket portion 3a, the gas from the air supply device 261 to the heating guide 262b To supply the gas from the space 262c to the temporary outer pocket 2c through the film 13 for the inner container. As a result, the temporary outer pocket portion 2 c is expanded to be in close contact with the lower die 263 at the portion where the concave portion 263 a is to be formed. As a result, the outer pocket portion 2 a and the outer flange portion corresponding portion 12 b are formed in the outer container film 12. In addition, the chamber H is formed between the two

pocket portions

2a and 3a, and the inside pocket portion 3a is accommodated in the outside pocket portion 2a. After forming the outer pocket portion 2a etc., the plug 262a is moved to the retracted position, and the upper mold 262 and the lower mold 263 are moved to the retracted position, respectively, to release the sandwiching of the two

container films

12 and 13.

In addition, the part clamped by the heating guide 262b and the lower mold | type 263 among the films |

membranes

12 and 13 for both containers will be in the state heated and welded. In the present embodiment, the holding step S12 corresponds to the preliminary welding step, and the heating guide 262b and the lower die 263 correspond to the preliminary welding means. The degree of welding in both the

container films

12 and 13 may be appropriately changed in accordance with the material to be used and the required performance of the blister pack 1 to be manufactured.

Returning to FIG. 6, in the subsequent supply step S2, the content C is supplied from the supply device 27 to the inner pocket 3a to supply the content C to the inner pocket 3a.

Next, in the sealing step S3, the preheated upper mold 29a and the lower mold 29b are disposed to approach positions, respectively, so that the overlapping portion of the outer flange corresponding portion 12b, the inner flange corresponding portion 13b and the cover film 14 Is sandwiched between the upper mold 29a and the lower mold 29b and heated. Thus, the inner flange portion corresponding portion 13b and the cover film 14 are welded to the outer flange portion corresponding portion 12b. As a result, the openings of the two

pocket portions

2a and 3a are closed by the cover film 14, and the interiors of the two

pocket portions

2a and 3a are sealed, whereby the blister film 11 is obtained. Thereafter, the upper mold 29a and the lower mold 29b are respectively moved to the retracted position to release the sandwiching of the

films

12, 13 and 14.

Finally, in the punching step S4, the outer periphery of the welded portion of each of the

films

12, 13 and 14 in the blister film 11 is punched out by the punching device 30. As a result, a blister pack 1 is obtained.

As described above in detail, according to the present embodiment, the sealing device 29 heats the overlapping portion of the outer flange portion corresponding portion 12b, the inner flange portion corresponding portion 13b, and the cover film 14 to form the outer flange portion. The inner flange corresponding portion 13b and the cover film 14 are welded to the corresponding portion 12b. That is, the sealing device 29 welds both the inner container 3 and the cover 4 to the outer container 2 at one time. Therefore, the step of attaching the outer container 2 and the inner container 3 and the step of closing the opening of the outer container 2 or the like by the cover 4 can be performed simultaneously. Thereby, the blister pack 1 of a special shape provided with the accommodation space of the content C and the chamber H can be efficiently produced at high speed inside the outer container 2 and the production efficiency can be improved. .

Moreover, while manufacturing the inner side container 3 and the outer side container 2 from the

films

12 and 13 for containers used as material, both can be combined and the blister pack 1 can be obtained. Therefore, there is no need for a step of prefabricating a container that constitutes a part of the blister pack and supplying (conveying) it to the blister packaging machine 20. As a result, it is possible to reduce the time and effort for manufacturing the blister pack 1 and to manufacture the blister pack 1 more efficiently and at higher speed. As a result, the production efficiency can be further improved.

Furthermore, the blister pack 1 is in a state in which the inner flange portion 3 b is held and fixed by the outer flange portion 2 b and the cover 4. Therefore, the inner container 3 can be fixed to the outer container 2 in a stable state, and peeling of the inner container 3 from the outer container 2 can be more reliably prevented.

Further, the pocket forming device 26 forms both the inner pocket 3a and the outer pocket 2a having different depths. Therefore, simplification of the blister packaging machine 20 can be achieved compared with the case where the formation apparatus of each

pocket part

2a and 3a is provided separately.

Furthermore, although the plug 262a is basically for forming the inner pocket portion 3a with respect to the film 13 for inner container, not only the inner pocket portion 3a but also the temporary outer pocket portion with respect to the film 12 for outer container 2c (that is, a gas supply space) is formed together. Therefore, the temporary outer pocket portion 2c can be formed simultaneously with the formation of the inner pocket portion 3a without particularly providing a process for forming the temporary outer pocket portion 2c. Therefore, the production efficiency can be further improved.

In addition, since the air permeability of the film 13 for inner container is effectively used when forming the outer pocket 2a and the chamber H, the outer pocket 2a and the like can be formed by a relatively simple method. This can further improve the production efficiency.

At the same time, by pressing the film 13 for the inner container with the heated plug 262a, the inner pocket portion 3a can be heated and stretched, and its shape can be fixed. Therefore, the shape of the inner pocket portion 3a can be more reliably kept constant, and the contents C can be accommodated more reliably and stably in the inner pocket portion 3a. Further, even if a high temperature object such as hot water contacts the inner pocket 3a, the inner pocket 3a can be prevented from shrinking and deforming, so the use of the blister pack 1 can be further expanded.

In addition, in the outer pocket portion forming step S14, supply of gas for expanding the temporary outer pocket portion 2c is performed while the inner pocket portion 3a is supported by the plug 262a. Thus, deformation of the inner pocket 3a due to air flow or the like when expanding the temporary outer pocket 2c can be suppressed, and the inner pocket 3a can be more reliably aimed at a shape.

Furthermore, since both the

container films

12 and 13 are preheated by the heating device 25 before pressing by the plug 262a, the pocket portion forming device 26 can more easily form the inner pocket portion 3a and the outer pocket portion 2a. Can. In addition, in order to heat the

films

12 and 13 for both containers at one time by the heating device 25, simplification of the blister packaging machine 20 compared to the case where heating devices are separately provided corresponding to the

films

12 and 13 for each container. And can be further miniaturized.

In addition, since the inner container film 13 is a non-woven fabric, it is possible to more easily allow the entire region of the inner container film 13 to have sufficient air permeability. Therefore, at the time of supply of gas, the temporary outside pocket part 2c can be expanded more reliably, and the formation mistake of the outside pocket part 2a can be prevented effectively.

Furthermore, since the film 13 for the inner container is a non-woven fabric, the surface area of the film 13 for the inner container can be made large, and the adhesion of the film 13 for the inner container to the film 12 for the outer container and the film 14 for the cover is strong. It can be As a result, good sealability can be realized in the obtained blister pack 1.

Further, before welding the cover film 14, the inner flange corresponding portion 13 b and the outer flange corresponding portion 12 b are welded by the heating guide 262 b and the lower die 263 as a preliminary welding unit. Therefore, in the blister film 11 obtained through the sealing step S3, the both flange

portion corresponding portions

12b and 13b and the cover film 14 can be more firmly fixed. As a result, extremely good sealability can be realized in the obtained blister pack 1.

(B) In the above embodiment, in the outer pocket forming step S14, the temporary outer pocket 2c is expanded by supplying gas to the temporary outer pocket 2c through the inner container film 13 to expand the outer pocket 2a. It is formed. On the other hand, as shown in FIG. 9, a predetermined negative pressure is supplied to the inside of the recess 263a of the lower die 263, for example, by a negative pressure supply device 264 as an outer pocket portion forming means consisting of a vacuum pump. The temporary outer pocket portion 2c may be expanded to form the outer pocket portion 2a by suctioning the portion 2c to the side opposite to the inner pocket portion 3a. Also in this case, the temporary outer pocket portion 2c can be expanded more reliably by utilizing the air permeability of the film 13 for the inner container, and the outer pocket portion 2a and the chamber H can be formed more reliably. Can. The outer pocket portion 2a may be formed by simultaneously performing the supply of gas to the temporary outer pocket portion 2c and the suction of the temporary outer pocket portion 2c.

That is, as shown in FIG. 13, the pocket portion forming step S1 includes a temporary pocket portion forming step S15 for forming the temporary inner pocket portion 3c and the temporary outer pocket portion 2c and the outer pocket portion 2a following the holding step S12. An outer pocket portion forming step S16 to be formed and an inner pocket portion forming step S17 to form the inner pocket portion 3a may be included. In this case, after the outer pocket portion 2a is formed, the inner pocket portion 3a is finally formed. Therefore, the inner pocket 3a can be more reliably formed into a desired shape.

(D) In the above embodiment, the inner pocket portion 3a is formed by pressing the inner container film 13 with the heated plug 262a, and the inner pocket portion 3a is thermally fixed. On the other hand, the inner pocket portion 3a may be formed by pressing the inner container film 13 with the plug 262a at normal temperature, and the inner pocket portion 3a may be gradually contracted as time passes. In this case, the content C is held between the cover 4 and the inner pocket portion 3a, for example, using the contraction of the inner pocket portion 3a so that the content C does not move easily in the inner pocket portion 3a. And the content C can be held in a compressed state.
