[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments will be described with reference to the drawings. As shown in FIG. 1, the bag-forming base material 1 with a stopper includes a rectangular packaging material 11 that is stacked two times, a stopper 12 that is inserted into an upper edge of the stacked packaging material 11, An upper lateral seal portion 13 that seals the upper edge portion of the packaging material 11 together with the plug 12, and a pair of vertical seal portions 14 that seal the side edge portion of the packaging material 11 from both ends of the upper lateral seal portion 13. And a plurality of bag portions 10 each having a lower lateral seal portion 15 that seals a lower edge portion of the packaging material 11 are formed in a long band shape that is successively arranged in one direction via the vertical seal portion 14. The vertical seal portion 14 is formed with perforations 16 for partitioning the adjacent bag portions 10.
[0011]
The packaging material 11 includes an inner layer made of a heat-fusible resin film such as polyethylene or polypropylene, a biaxially stretched polyester film, a biaxially stretched polyamide film, a biaxially stretched polypropylene film, or the like, or a known gas for these films. It is formed by a laminated film composed of an outer surface layer on which a barrier film or the like is laminated, and a plug 12 made of the same kind of material as the inner surface layer of the packaging material 11 is inserted into the upper edge of the packaging material 11. In this state, the two overlapping packaging materials 11 are heat-bonded over the entire circumference, so that the upper horizontal seal portion 13, the vertical seal portion 14, and the lower horizontal seal portion 15 are formed.
[0012]
The bag-forming base material 1 with a stopper configured as described above is configured such that the stoppers 12 are sequentially inserted at regular intervals into the upper edge of the strip-shaped packaging material 11 conveyed in a two-layered state. Thus, the upper and lower lateral seal portions 13 and 15 are formed by thermally bonding the upper edge portion and the lower edge portion into which the spigot 12 has been inserted, and the vertical seal bar at a predetermined interval. After the longitudinal seal portion 14 is sequentially formed by thermal bonding with a predetermined width from the upper edge portion to the lower edge portion of the packaging material 11, a perforation 16 is sequentially formed at the center portion in the width direction of the longitudinal seal portion 14. Manufactured by doing.
[0013]
In addition, the bag-forming base material 1 with a stopper has the above-mentioned upper side seal part 13, the vertical seal part 14 and the lower side part in a sterile state in which the packaging material 11 and the stopper 12 are sterilized in the manufacturing process described above. Since the seal part 15 is formed, the sealed inside of the bag part 10 is maintained in a sterile state.
[0014]
As shown in FIG. 2 (a), the cap-formed bag-forming base material 1 manufactured as described above has a perforation 16 for each predetermined length (a length including a predetermined number of the bag portions 10). While being folded alternately, it is packed in a packaging box C, stored and transported in that state, and supplied to a manufacturer (such as a beverage manufacturer) of the bag-forming base material 1 with plugs.
[0015]
On the other hand, as shown in FIG. 2, the manufacturer that supplied the bag-forming base material 1 with a cap produces a bag with a plug filled with the contents using the bag-forming base material 1 with a plug. To do.
[0016]
First, as shown in FIG. 2A, after the bag-forming base material 1 with a cap packed in a packaging box C is fed out, the bag-forming base material 1 with a plug is placed with the plug 12 facing downward. In this state, the bag is supplied to a sterilization chamber R (shown by a one-dot chain line in the figure) in which bag making and filling of contents are performed. The outer surface is sterilized by immersing the forming substrate 1 in a sterilization tank (not shown) filled with hydrogen peroxide.
[0017]
Next, in the sterilization chamber R, as shown in FIG. 2B, first, the lower side seal portion 15 is cut by the filling port forming means 21 to thereby form the bag forming base material 1 with a plug. A filling port for the contents is formed in each bag portion 10 constituting the.
[0018]
And the filling nozzle 22 of the content is inserted in each bag part 10 from the filling port formed by the lower side seal part 15 being cut off, and the content is put in each bag part 10 through this filling nozzle 22. Fill things. The bag portion 10 filled with the contents is heat-bonded to the filling port portion by the horizontal seal bar 23 to form the lower side seal portion 17 again, and the contents are sealed in each bag portion 10. The
[0019]
In this way, the bag-forming base material 1 with plugs in which the contents are sealed and filled in each bag portion 10 is sent out from the aseptic chamber R and sequentially cut at the perforation 16 portion. The bag P with the stopper filled with the contents is obtained.
[0020]
As described above, the bag-forming base material 1 with a stopper is attached in advance in a state where the stopper 12 is sealed to the upper edge portion of the packaging material 11. A container using manufacturer such as a beverage manufacturer that manufactures a bag with a plug P filled with the contents using the bag does not need to be attached with a plug 12 in the bag making and filling process. The burden such as management of seal leakage is reduced.
[0021]
Moreover, since the container maker which manufactures this bag forming base material 1 with a stopper can fully perform the seal | sticker test | inspection of the stopper 12 part before shipment, container use manufacturers, such as a drink maker who is not familiar with a container. However, there is an advantage that the reliability is high and the quality of the product is improved as compared with the case where the seal is inspected after the contents are filled.
[0022]
Further, in this embodiment, the bag forming base material 1 with a stopper is packed in a folded state, but is not limited to such a form. For example, as shown in FIG. It can also be stored, transported and used while being wound in a shape.
[0023]
Moreover, since this bag forming base material 1 with a cap is in the shape of a long belt, the container maker can store and ship in a state of being folded and boxed or wound in a roll shape as described above. In addition, a container manufacturer such as a beverage manufacturer can easily set it in a bag making and filling device or the like while being supplied almost. Therefore, as in the case of supplying a finished bag with a stopper, the complicated work that occurs in the distribution process of the bag with a stopper and the filling process of the contents into the stoppered bag is eliminated. There is an advantage that the production efficiency of both is improved.
[0024]
In this embodiment, in order to fill the contents, the lower side seal 15 once formed is cut off. However, when the plug 12 is a screw cap type, the contents are plugged into the plug 12 portion. It can also be filled directly from.
[0025]
Specifically, after removing the screw cap attached to the mouth portion in advance, or after removing the film lid 12a closing the mouth portion 12b, as shown by a one-dot chain line in FIG. As shown in the figure (b), the contents may be filled from the mouth part 12b, and as shown in the figure (c), the screw cap 12c is attached again to close the mouth part 12b. In addition, when filling the contents from the plug portion in this way, as in the bag-forming base material 1 with the plug, the plug portion is attached so that the plug portion faces downward in the bag making and filling process. Needless to say, it is not necessary to erect the bag-forming base material, and the contents may be filled in a state where the bag plug portion is erected so as to face upward.
[0026]
In this way, in the case where the contents are filled from the plug portion, a container manufacturer such as a beverage manufacturer performs a sealing work that may cause a leak in the bag making and filling process. Since there is no need to do anything, the quality of the product is further improved.
[0027]
Further, the above-mentioned bag-forming base material 1 with a cap forms the upper horizontal seal portion 13 and the vertical seal portion 14 in an aseptic state in order to omit the cleaning operation in each bag portion 10 during use, In order to seal the bag in a sterile state, the lower side seal portion 15 is formed. However, if the inside of the bag portion 10 is washed before filling the contents, the lower side seal portion 15 is formed as shown in FIG. There is no need to form a transverse seal. In this case, needless to say, the filling port forming means 21 described above is not necessary. In addition, when the contents are directly filled from the plug 12 portion, it is not necessary to seal with the screw cap 12c or the film lid 12a in advance, and the screw cap 12c or the like may be attached after filling.
[0028]
Moreover, in each embodiment mentioned above, although the packaging material 11 is used in the state of two-ply, for example, one piece of packaging material is put in a folded state, and the plug 12 is inserted into the butt edge and sealed. In this case, it is not necessary to form the lower lateral seal portion 15 in particular, and the filling port for the contents may be formed by cutting the folded edge. However, in the case of filling the contents from the plug portion, it is possible to seal the folded edge before filling the contents in order to reinforce the folded edge.
[0029]
Moreover, in each embodiment mentioned above, although the perforation 16 is formed in the vertical seal | sticker part 14, this perforation 16 does not necessarily have to provide, but after filling the contents, a cutting blade etc. Thus, the vertical seal portion 14 may be cut at the center in the width direction or trimmed to a predetermined shape. However, when the perforated bag forming base material 1 is boxed by providing the perforation 16 and the notches, the folded portion does not become bulky by folding at the perforated 16 portion. Since it has the effect that it can be bent easily, it can be said that it is a desirable form to provide the perforation 16 and the cut.
[0030]
Moreover, in each embodiment mentioned above, although the plug is attached to the joint edge which is the upper edge part of the packaging material folded or folded in two, for example, the mouth plug is attached to the folded edge which is the upper edge part of the packaging material. The attachment hole may be formed, and the mouth plug may be attached so that the mouth portion protrudes from the attachment hole.
[0031]
【The invention's effect】
As described above, in the bag making and filling method of a bag with a plug according to the present invention, since the bag forming base material with a plug having a plug portion sealed in advance is used , a seal leak is likely to occur. It is not necessary to perform the sealing work of the plug part in the bag making and filling process, and since the bag forming base material with a plug is a long band shape, it is wound in an alternately folded state or a roll shape. It can be transported and stored in a state, and can be easily set in a bag making and filling device .
[0032]
Therefore, unlike the conventional case, there is no complicated work in the process of distributing the plug-forming bag forming base material and the bag-filling process of the bag with the plug, improving the production efficiency of both the container manufacturer and the container using manufacturer, This has the effect of reducing the burden on the manufacturer and increasing the reliability of the finished product.
