Description

The present invention relates to a process for the production of blister packaging machine and blister packs for the production of blister pack containing a predetermined content.

  The blister pack includes a container having a pocket portion in which various contents are accommodated, and a cover attached to the container so as to seal the opening side of the pocket portion. The blister pack is manufactured by a blister packaging machine provided with various means such as a pocket part forming means for forming a pocket part.

  By the way, as a kind of packaging body such as a blister pack, a bag-like filter in which contents are stored, and an opening-side outer peripheral portion of the bag-like filter are attached to its own opening-side inner peripheral portion (side wall portion). A cup-type container that accommodates the bag-shaped filter in a state, and a cover that is attached to the cup-shaped container so as to close both openings of the bag-shaped filter and the cup-shaped container. There is known one in which a chamber (room) is formed between a filter and a cup-type container (for example, see Patent Document 1). This package contains coffee powder (eg, ground coffee or powder extract) in a bag-like filter, and when used, a tubular injection probe breaks through the cover and is placed in the bag-like filter. In addition, a tubular discharge probe is disposed in the chamber through the bottom of the cup-shaped container. When hot water is supplied into the bag-shaped filter through the injection probe, coffee is extracted into the chamber through the bag-shaped filter and sent out of the chamber through the discharge probe.

  Moreover, in the said patent document, the above packaging bodies are manufactured through the following process. That is, a bag-shaped filter is produced by bending or welding a band-shaped filter material that can be thermally welded. Next, a bag-shaped filter is placed inside a cup-shaped container manufactured in advance, and the opening of the bag-shaped filter is in an expanded state. Then, the opening side outer peripheral part of a bag-shaped filter and the opening side inner peripheral part of a cup type container are welded. And finally, after supplying coffee powder to a bag-shaped filter, a package is manufactured by closing an opening of a cup-shaped container or the like with a cover.

  The sealing device 29 includes an upper mold 29a and a lower mold 29b, both of which are separated from the films 12, 13, and 14 by the driving means (not shown) and the approach positions approaching the films 12, 13, and 14. It can be moved between the retracted positions. The upper mold | type 29a and the lower mold | type 29b are each arrange | positioned to an approach position, and pinch | interpose each film 12,13,14. Further, at least a portion of the upper mold 29a where the films 12, 13, and 14 are sandwiched between the lower mold 29b can be heated by a heater or the like (not shown). In addition, the sealing process (sealing process) of both pocket parts 2a and 3a by the sealing device 29 will be described 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) for cutting a scrap portion remaining after the punching is disposed downstream of the punching device 30. The scrap portion is cut into a predetermined size by the cutting device and stored in a predetermined scrap hopper (not shown).

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

  Next, the manufacturing process of the blister pack 1 using the blister packaging machine 20 will be described. As shown in FIG. 6, the manufacturing process of the blister pack 1 includes 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 sandwiching 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 both the container films 12 and 13 is heated at once by the heating device 25.

  Next, in the sandwiching step S12, the upper mold 262 and the lower mold 263 are respectively disposed at the approach positions, whereby the both container films 12 and 13 that are temporarily stopped are sandwiched between the upper mold 262 and the lower mold 263. More specifically, the portions that become the outer flange portion corresponding portion 12b and the inner flange portion corresponding portion 13b of the container films 12 and 13 are sandwiched between the upper surfaces of the heating guide 262b and the lower mold 263. At this time, the plug 262a is disposed at the immersion position. Further, the plug 262a and the heating guide 262b are preheated.

  Next, in the inner pocket portion forming step S13, as shown in FIG. 7, the plug 262a is moved to the protruding position while the both container films 12 and 13 are held between the heating guide 262b and the lower mold 263. Thereby, the plug 262a protrudes from the lower surface of the heating guide 262b so as to enter the recess 263a. Then, the container films 12 and 13 in an overlapped state are pressed by the plug 262a, and both the container films 12 and 13 are deformed along the distal end surface of the plug 262a. As a result, the inner pocket portion 3 a and the inner flange portion corresponding portion 13 b are formed on the inner container film 13. The inner pocket portion 3a is heat-fixed and its shape is stably maintained. Further, a temporary outer pocket portion 2c having substantially the same shape as the inner pocket portion 3a is formed on the outer container film 12.

  Thereafter, in the outer pocket forming step S14, as shown in FIG. 8, the gas is supplied from the air supply device 261 to the heating guide 262b while the plug 262a is disposed in the recess 263a and supports the inner pocket 3a. And the gas is supplied from the space 262c through the inner container film 13 to the temporary outer pocket portion 2c. Thereby, the temporary outer side pocket part 2c is expanded and it adheres to the site | part which forms the recessed part 263a in the lower mold | type 263. FIG. 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. Further, a chamber H is formed between the pocket portions 2a and 3a, and the inner pocket portion 3a is accommodated in the outer pocket portion 2a. After the outer pocket portion 2a and the like are formed, the plug 262a is moved to the immersive position, and the upper mold 262 and the lower mold 263 are moved to the retracted positions, respectively, so that the holding of the container films 12 and 13 is released.

  In addition, the site | part clamped by the heating guide 262b and the lower mold | type 263 among both the film | membranes 12 and 13 will be in the state welded by heating. In the present embodiment, the sandwiching step S12 corresponds to a preliminary welding step, and the heating guide 262b and the lower mold 263 correspond to preliminary welding means. In addition, you may change suitably the grade of the welding in the films 12 and 13 for both containers according to the material to be used, the performance requirement of the blister pack 1 manufactured, etc.

  Returning to FIG. 6, in the subsequent supply step S <b> 2, the content C is supplied from the supply device 27 to the inner pocket portion 3 a to supply the content C to the inner pocket portion 3 a.

  Next, in the sealing step S3, the upper mold 29a and the lower mold 29b, which are heated in advance, are disposed at the approach positions, respectively, so that the outer flange portion corresponding portion 12b, the inner flange portion corresponding portion 13b, and the cover film 14 overlap each other. Is sandwiched between the upper mold 29a and the lower mold 29b and heated. Thereby, the inner flange part corresponding part 13b and the cover film 14 are welded to the outer flange part corresponding part 12b. As a result, each opening of the pocket portions 2a and 3a is closed by the cover film 14, and the inside of the pocket portions 2a and 3a is sealed, whereby the blister film 11 is obtained. Thereafter, the upper mold 29a and the lower mold 29b are moved to the retracted positions, respectively, and the clamping of the films 12, 13, and 14 is released.

  Finally, in the punching step S4, the punching device 30 punches the outer periphery of the blister film 11 near the welded portion of the films 12, 13, and 14. As a result, the 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 thereby form the outer flange portion. The inner flange portion 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 a time. Therefore, the process of attaching the outer container 2 and the inner container 3 and the process of closing the opening of the outer container 2 and the like by the cover 4 can be performed simultaneously. As a result, the blister pack 1 having a special shape provided with the storage space for the contents C and the chamber H inside the outer container 2 can be manufactured efficiently and at high speed, and the production efficiency can be improved. .

  Moreover, while producing the inner container 3 and the outer container 2 from the container films 12 and 13 used as materials, the blister pack 1 can be obtained by combining the two. Therefore, there is no need for a process in which a container constituting a part of the blister pack is manufactured in advance and then supplied (conveyed) to the blister packaging machine 20. Thereby, the effort and labor at the time of manufacture of blister pack 1 can be reduced, and blister pack 1 can be manufactured more efficiently and faster. As a result, the production efficiency can be further improved.

  Further, the blister pack 1 is in a state in which the inner flange portion 3b is sandwiched and fixed by the outer flange portion 2b and the cover 4. Therefore, the inner container 3 can be stably fixed to the outer container 2, and the inner container 3 can be more reliably prevented from being peeled off from the outer container 2.

  Further, the pocket portion forming device 26 forms both the inner pocket portion 3a and the outer pocket portion 2a having different depths. Therefore, the blister packaging machine 20 can be simplified as compared with the case where the forming devices for the pocket portions 2a and 3a are separately provided.

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

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

  In addition, by pressing the inner container film 13 with the heated plug 262a, the inner pocket portion 3a can be heated and stretched to fix its shape. Therefore, the shape of the inner pocket portion 3a can be more reliably maintained constant, and the contents C can be more reliably accommodated in the inner pocket portion 3a in a stable state. Further, even if a high-temperature object such as hot water comes into contact with the inner pocket portion 3a, the inner pocket portion 3a can be prevented from contracting and deforming, so that the use of the blister pack 1 can be further expanded.

  In addition, in the outer pocket portion forming step S14, gas for inflating the temporary outer pocket portion 2c is supplied while the inner pocket portion 3a is supported by the plug 262a. Thereby, the deformation | transformation of the inner side pocket part 3a by the airflow etc. at the time of expanding the temporary outer side pocket part 2c can be suppressed, and the inner side pocket part 3a can be made into the target shape more reliably.

  Furthermore, since both the container films 12 and 13 are preheated by the heating device 25 before being pressed by the plug 262a, the inner pocket portion 3a and the outer pocket portion 2a can be more easily formed by the pocket portion forming device 26. Can do. Moreover, since both the container films 12 and 13 are heated at a time by the heating device 25, the blister packaging machine 20 is simplified as compared with the case where the heating devices are separately provided corresponding to the respective container films 12 and 13. And further downsizing.

  In addition, since the inner container film 13 is a non-woven fabric, it becomes easier to give sufficient air permeability to the entire area of the inner container film 13. Therefore, the provisional outer pocket portion 2c can be expanded more reliably at the time of gas supply, and the formation mistake of the outer pocket portion 2a can be effectively prevented.

  Furthermore, since the inner container film 13 is a non-woven fabric, the inner container film 13 can have a large surface area, and the inner container film 13 can be firmly fixed to the outer container film 12 and the cover film 14. Can be. As a result, good sealing performance can be realized in the obtained blister pack 1.

  Further, before the cover film 14 is welded, the inner flange portion corresponding portion 13b and the outer flange portion corresponding portion 12b are welded by the heating guide 262b and the lower mold 263 as preliminary welding means. Therefore, in the blister film 11 obtained through the sealing step S3, the flange corresponding parts 12b and 13b and the cover film 14 can be more firmly fixed. As a result, extremely good sealing performance can be realized in the obtained blister pack 1.
