Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base material for forming a bag with a plug for forming a bag with a plug, and a method for making and filling a bag with a plug using the base material for forming a plug with a plug.

[0002]

2. Description of the Related Art In recent years, beverages such as soft drinks, seasonings such as sauces, and medicines such as eye drops have been gradually distributed and sold after being filled into plugged bags such as pouch containers with plugs. As a bag with a plug of this type, for example, two synthetic resin films of a predetermined shape are superimposed, a plug is inserted between the peripheral portions of the synthetic resin film, and the entire peripheral portion is completely closed. Some are formed by welding over the circumference.

By the way, as a method of manufacturing such a product in which contents are filled in a bag with a stopper, a bag with a stopper formed in advance by a container maker is purchased, and a beverage maker or the like purchases the bag with the stopper. There are a method of filling the contents into the bag, and a method of allowing the beverage maker or the like to fill the contents while forming the above-mentioned plugged bag from the packaging material such as a synthetic resin film and the plug.

[0004]

However, as described above, when a bag with a plug is formed in advance and the contents are later filled into the bag with a plug, a container maker is formed. The bag with the stopper must be bundled with the direction of the bag with the stopper aligned, packed in a box, and shipped to a beverage maker or the like. In the process of distributing the spouted bag and filling the contents into the spouted bag, there is a lot of complicated work, such as having to take out and set it in the filling device. There is a problem that production efficiency deteriorates.

On the other hand, when a beverage maker or the like fills the contents while forming a bag with a stopper, the above-mentioned problem is solved, but the beverage maker or the like has a large apparatus for manufacturing a bag with a stopper. Must be purchased and installed.Moreover, workers such as beverage manufacturers who are not originally proficient in the manufacture of containers must manage the leakage of seals at the fittings of plugs, etc. The burden on the side was increasing.
Also, to fill the contents immediately after attaching the spout,
There is also a problem that it is difficult to inspect a seal failure or the like before filling.

Therefore, an object of the present invention is to reduce the production efficiency of a container maker and a maker using the container without reducing the production efficiency.
Moreover, it is an object of the present invention to provide a base material for forming a bag with a plug capable of reducing the burden of managing leakage of a seal in a plug portion, and a method for filling and filling a bag with a plug using the base material.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a packaging material which is overlapped in a two-ply or two-fold state, and a joining edge or an upper edge portion of the packaging material which is overlapped. A plurality of plugs having a plug inserted into the folded edge, a horizontal seal portion sealing the upper edge of the packaging material together with the plug, and a pair of vertical seal portions sealing side edges of the packaging material. An object of the present invention is to provide a long band-shaped plug-formed base material with a plug, the bag portion being sequentially connected in one direction via the vertical seal portion.

[0008] The bag-forming base material with a plug can be packed, transported, and stored in a state of being alternately folded at a predetermined length along a longitudinal direction or wound in a roll shape. When using the plug-formed bag-forming base material, it can be easily fed out by setting it in an apparatus or the like in a folded or wound state.

If the above-mentioned base material for forming a bag with a plug is used,
After sequentially filling the bag portions with the contents, the filling ports of the contents of the respective bag portions are sequentially closed, and the plug-formed bag-forming base material with the closed filling ports of the contents is vertically sealed. , It is possible to easily form a bag while filling the contents without sealing the plug portion, which tends to be a problem.

[0010]

Embodiments will be described below with reference to the drawings. As shown in FIG. 1, the base material 1 for forming a bag with a plug is made of a two-layered rectangular packaging material 11.
And a plug 12 to be inserted into the upper edge of the packaging material 11 superimposed thereon, and the plug material 12 together with the plug 12.
An upper horizontal seal portion 13 for sealing an upper edge portion, a pair of vertical seal portions 14 for sealing a side edge portion of the packaging material 11 from both ends of the upper horizontal seal portion 13, and a lower portion of the packaging material 11 A plurality of bag portions 10 having a lower horizontal seal portion 15 for sealing an edge portion are in the form of a long strip continuously connected in one direction via the vertical seal portion 14, and the vertical seal portion is provided. 14 is a perforation 16 for separating the adjacent bag portions 10.
Are formed.

The packaging material 11 includes an inner surface 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. The spout 12 is formed of a laminated film composed of a known gas barrier film and an outer layer laminated thereon, and a plug 12 formed of the same material as the inner layer of the packaging material 11 is attached to the upper edge of the packaging material 11. In the state where it is inserted in, the two packaging materials 11 which are superimposed,
The upper horizontal seal portion 13, the vertical seal portion 14, and the lower horizontal seal portion 15 are formed by heat bonding over the entire circumference.

In the bag-formed base material 1 with a plug configured as described above, the plugs 12 are sequentially inserted at regular intervals into the upper edge of the strip-shaped packaging material 11 conveyed in a two-ply state.
The upper side seal part 1 into which the plug 12 is inserted is thermally bonded to the upper side seal part 1 by a horizontal seal bar.
3 and the lower horizontal seal portion 15, and the vertical seal bar is thermally bonded at a predetermined interval from the upper edge to the lower edge of the packaging material 11 with a predetermined width, thereby sequentially bonding the vertical seal portions 14 with each other. After forming, this vertical seal portion 1
4 is manufactured by sequentially forming perforations 16 at the center in the width direction.

In the above-described manufacturing process, the bag-forming base material 1 with the plug is provided with the packaging material 11 and the plug 12.
Are sterilized, and the upper horizontal seal portion 13, the vertical seal portion 14, and the lower horizontal seal portion 15 are formed in an aseptic state, so that the inside of the sealed bag portion 10 is maintained in an aseptic state. .

As shown in FIG. 2 (a), the bag-formed base material 1 with a plug manufactured as described above is provided for every predetermined length (including the predetermined number of the bag portions 10). At the perforation 16 part, it is packed in the packaging box C while alternately folding it,
In this state, it is stored and transported, and is supplied to a maker (beverage maker or the like) using the plugged base material 1.

On the other hand, as shown in FIG. 2, the maker supplied with the plug-formed bag-forming base material 1 uses the plug-filled bag-formed base material 1 filled with contents as shown in FIG. Manufacture bags.

First, as shown in FIG.
After feeding out the bag-formed base material 1 with a spout packed in a box,
In a state in which the plug-formed bag-forming base material 1 is erected so that the plug 12 faces downward, bag making and filling of contents are performed in a sterile room R (indicated by a dashed line in the figure). In a position immediately before the sterile chamber R, the bag-forming base material 1 with a plug is immersed in a sterilization tank (not shown) or the like filled with a hydrogen peroxide solution. Is sterilized.

Next, in the aseptic chamber R, as shown in FIG. 1B, the lower lateral seal portion 15 is first cut off by the filling port forming means 21 to form a bag with a plug. A filling port for contents is formed in each bag portion 10 constituting the base material 1.

Then, a filling nozzle 22 for the contents is inserted into each bag portion 10 from a filling port formed by cutting off the lower horizontal seal portion 15, and each bag portion 10 is inserted through the filling nozzle 22. Fill the contents. 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 horizontal seal portion 17 again, and the contents are sealed in each bag portion 10. You.

In this way, the cap-formed bag-forming base material 1 in which the contents are sealed and filled in the respective bag portions 10 is provided in the sterile room R
From the outside, and sequentially cut at the perforation 16 to thereby fill the bag P with a plug filled with the contents.
Becomes

As described above, this bag-formed base material 1 with a plug is used.
Since the plug 12 is attached in advance in a state where the plug 12 is sealed to the upper edge portion of the packaging material 11, the bag P with the plug filled with the contents using the plug-forming base material 1 with the plug is attached. It is not necessary for a manufacturer using a container such as a beverage maker to manufacture the container to attach the plug 12 in the bag making and filling step, so that the burden of sealing leakage management at the plug 12 which is likely to cause a problem is reduced.

In addition, since the container maker that manufactures the plug-formed base material 1 can sufficiently inspect the seal of the plug 12 before shipment, it can be used by beverage manufacturers who are not familiar with the container. Compared to the case where the container manufacturer inspects for sealing failure after filling the contents, the reliability is higher,
There is also an advantage that the quality of the product is improved.

Further, in this embodiment, the bag-formed base member 1 with a plug is packed in a box in a folded state. However, the present invention is not limited to such a form. For example, as shown in FIG. In a state wound in a roll, storage, transport,
Can also be used.

Further, since the base material 1 for forming a bag with a plug is in the form of a long strip, the container maker can store and store it in a state of being folded and packed in a box or wound in a roll as described above.
Shipping can be performed, and manufacturers using containers such as beverage manufacturers,
It can be easily set in a bag making and filling device or the like while almost supplied. Therefore, as in the case of supplying a completed plugged bag, complicated operations that occur in the process of distributing the plugged bag and filling the contents with the plugged bag are eliminated, and the container manufacturer and the manufacturer who uses the container are eliminated. There is an advantage that both production efficiencies are improved.

Further, in this embodiment, the lower horizontal seal 15 formed once is cut off in order to fill the contents. However, when the plug 12 is a screw cap type, the contents are opened. It can also be filled directly from the stopper 12 part.

Specifically, after removing the screw cap previously attached to the mouth portion, or as shown by the dashed line in FIG. 4A, remove the film lid 12a closing the mouth portion 12b. After that, as shown in FIG.
The contents may be filled from the mouth portion 12b, and the screw portion 12c may be attached again to close the mouth portion 12b as shown in FIG. In addition, when filling the contents from the plug portion in this way, as in the case of the above-described plug-formed bag-forming base material 1, the plug is placed so that the plug portion faces downward in the bag making and filling step. It is needless to say that it is not necessary to raise the bag-forming base material, and it is sufficient to fill the contents in a state where the plug portion is raised so as to face upward.

As described above, in the case of filling the contents from the plug portion, there is a possibility that a maker using a container such as a beverage maker may cause leakage in the bag making and filling steps. Since there is no need to perform any sealing work, the quality of the product is further improved.

Further, the above-mentioned base material 1 for forming a bag with a plug is
In order to omit the washing operation in each bag part 10 at the time of use, the upper horizontal seal part 13 and the vertical seal part 14 are formed in an aseptic state, and the lower horizontal seal part is sealed in an aseptic state. 15, but before filling the contents,
If the inside of the bag portion 10 is to be cleaned, it is not necessary to form the lower horizontal seal portion as shown in FIG. In this case, it goes without saying that the above-described filling port forming means 21 is not required. When the contents are directly filled from the plug 12, it is not necessary to seal the contents with the screw cap 12 c or the film lid 12 a in advance, and the screw cap 12 c or the like may be attached after filling.

Further, in each of the above-described embodiments, the packaging material 11 is used in a two-ply state. For example, one piece of the packaging material is overlapped in a two-fold state, and the plug 12 is inserted into the butting edge. In such a case, it is not necessary to particularly form the lower horizontal sealing portion 15, and the filling port of the content may be formed by cutting the folded edge. However, in the case where the contents are filled from the plug portion, it is all right to seal the folded edges before filling the contents in order to reinforce the folded edges.

Further, in each of the above-described embodiments, the perforations 16 are formed in the vertical seal portion 14. However, the perforations 16 are not necessarily provided. The vertical seal portion 14 may be cut at the center in the width direction by a cutting blade or the like, or may be trimmed into a predetermined shape. However, by providing the perforations 16 and the cuts, the perforations 16 are formed when the bag-formed base material 1 with a plug is packed in a box.
By folding at the portion, the bent portion does not become bulky and has an effect that it can be easily bent. Therefore, it can be said that it is a desirable form to provide the perforations 16 and cuts.

Further, in each of the above-described embodiments, the plug is attached to the seam edge, which is the upper edge of the two-ply or two-fold packaging material. For example, the folded edge, which is the upper edge of the packaging material, is used. May be formed with an opening for attaching a plug, and the plug is attached so that the mouth portion protrudes from the mounting hole.

[0031]

As described above, the plug-forming bag-forming base material of the present invention has the plug portion sealed in advance, so that the sealing operation of the plug portion is likely to occur. Need not be performed during the bag making and filling process.
Since the bag-forming base material with a plug is in the form of a long strip, it can be transported and stored in a state of being alternately folded or wound in a roll shape, and can be easily set in a bag making and filling device.

Therefore, unlike the prior art, complicated operations in the process of distributing the base material for forming a bag with a plug and the step of making and filling the bag with a plug are eliminated, and the production efficiency of both the container maker and the maker using the container is improved. In addition, the burden on the manufacturer of the container is reduced, and the reliability of the finished product is increased.
