[0001]
BACKGROUND OF THE INVENTION
In the present invention, when a viscous or pasty liquid such as shampoo, body shampoo, rinse, liquid detergent, cosmetic cream is used in a container with a spout, the container with a spout is discarded after use. The refill packaging bag for refilling and the container with spout are improved in order to facilitate refilling of the contents from the refilling packaging bag for refilling into the container with spouting.
[0002]
[Prior art]
Conventionally, when a viscous or pasty liquid such as shampoo, body shampoo, rinse, liquid detergent, cosmetic cream, etc. is used in a container with a spout, the contents are almost always left as it is. It is currently being discarded.
[0003]
In addition, in order to eliminate waste pollution and economic disadvantages due to the disposable container, a container with a spout is partially reused, and an optional product in a bag is supplied for replenishment.
Most of the separately sold products are standing pouches (bottom gusset free-standing bags) or pillow-wrapped products. When refilling, cut off a part of the packaging bag or use a V-notch provided on the packaging bag. It was then opened and transferred to an empty container.
However, since containers with spouts are generally small in size, the transfer from a packaging bag to a container is cumbersome, and the contents are spilled out of the container at the time of refilling. Due to the consistency, the contents could not be sufficiently discharged from the packaging bag, and there was a problem that the contents remained in the packaging bag.
[0004]
[Problems to be solved by the invention]
Waste pollution caused by disposable containers is a major social problem. For those involved in packaging and containers, how to reduce the amount of garbage after use by eliminating packaging and containers as much as possible and minimizing the form. It has become a big issue.
Therefore, attempts have been made to solve the above problems by recycling and reusing packaging and containers.
Also, in the case of a conventional refill packaging bag, the contents are spilled out of the container at the time of refilling, and the contents are viscous, so the hands are dirty to squeeze out the contents, or the contents are in the bag There were problems such as remaining.
[0005]
In order to solve the above problems, the present invention is to use the liquid dispensing container repeatedly after the contents are consumed without being discarded, and to use the contents in the refill bag as the first container. It is intended to be supplemented and used.
Further, by using a bag made of a soft packaging material for the refill packaging bag, the volume after use is extremely reduced, and the amount of dust is reduced.
Furthermore, in the present invention, since the weakly bonded portion is provided in addition to the heat seal portion at the lower portion of the refill packaging bag, when the refill is carried out, the weakly sealed portion is left behind and the heat seal portion is removed, and then the liquid pouring container is filled. By squeezing out the contents of the packaging bag using the notch provided on the lid, the weakly bonded part of the refillable packaging bag is broken, and even the viscous contents can be easily pushed out. It can be easily transferred to the container without leaving.
[0006]
[Means for Solving the Problems]
As a result of various studies to solve the above-described problems, the present invention provides a refillable packaging bag as follows.
The packaging bag is made of a flexible material, has a hole that allows fingers to enter the upper seal part, forms a weak adhesive part on the upper part of the lower seal part, and is intermediate between the side seal parts of the weak adhesive part The easy-to-refill packaging bag was provided by providing an easy-open portion.
In addition, the packaging bag is a gusset bag, a four-sided seal bag, or a joint-attached three-sided seal bag, and an easily refillable packaging bag having an adhesive strength of 200 to 900 g / 15 mm width at the weakly bonded portion.
[0007]
Furthermore, at the time of refilling, the V-notch of the refill packaging bag is used to remove at least a part of the weakly bonded portion and remove the lower seal portion, and then the refill packaging bag provided on the inner lid of the liquid dispensing container The upper portion of the packaging bag is sandwiched in the notch for handling the packaging bag, and the packaging bag is lifted using the handle hole provided in the upper portion of the packaging bag, so that the packaging bag is handled by the incision of the inner lid. Thus, the weakly bonded portion is broken and the contents can be easily squeezed out into the container.
Further, by setting the gap of the notch to an appropriate interval according to the thickness of the packaging bag, the contents of the packaging bag are well squeezed out by the notch, and there is almost no residue in the packaging bag.

The easily refillable packaging bag of the present invention is used as a refillable packaging bag 2 for the liquid dispensing container 1 as shown in FIG.
Then, the refillable packaging bag 2 of the present invention uses a notch provided in the inner lid 10 of the liquid dispensing container 1 as shown in FIG. By pulling up the bag 2 and handling the packaging bag 2, the weakly bonded portion 25 formed on the packaging bag 2 is broken and the contents 5 are squeezed out into the container 4.
[0011]
As shown in FIG. 3, the liquid dispensing container 1 includes an inner lid 10, a container 4, and a dispenser 3.
In addition, the thing with the same structure as the conventional thing was used for the extractor 3. FIG.
As shown in FIG. 3B, the container 4 of the liquid dispensing container 1 has a wide opening so that a refillable packaging bag can be easily placed in the container 4.
Further, a screw thread 7 is formed outside the opening of the container 4, and the container 4 and the dispenser 3 are screwed together by a screw lid 6 provided in the dispenser 3, and the contents Prevents leakage.
Further, an inner lid 10 as shown in FIG. 3A is fitted inside the opening of the container 4 to constitute the liquid dispenser 1 as shown in FIG.
[0012]
As shown in FIG. 3A, the inner lid 10 is provided with a cylindrical upright portion 15 at the center of the base portion 16, and a skirt portion 17 for fitting the container 4 at the lower portion of the base portion 16. Is formed.
Further, a notch 11 for sandwiching the refilling packaging bag and handling the packaging bag is provided at the periphery of the base portion.
As shown in FIG. 4A, an outer thick portion 12 and an inner thick portion 13 are formed on both sides of the notch 11.
As shown in FIG. 4B, a skirt portion 17 and a stopper 18 for positioning the packaging bag when the refilling packaging bag is inserted are provided on the back side of the inner lid 10.
[0013]
The inner lid 10 is provided with a skirt portion 17 on the back side thereof, and is fitted into the wide-mouth opening of the container 4.
Further, on the front side, a cylindrical upright portion 15 is formed at the center of the base portion 16, and the suction pipe 9 of the dispenser 3 shown in FIG. 3C is inserted into the hole 14 of the upright portion 15. It has become so.
And after putting contents, such as a shampoo, in the container 4 and fitting the inner lid, the suction pipe 9 of the dispenser 3 is inserted into the hole 14 of the standing portion 15 of the inner lid 10, and the dispenser By screwing the screw cap 6 and the container 4 together, the dispenser 3 and the container 4 are integrated to form the liquid dispenser 1 as shown in FIG.
[0014]
When the user no longer consumes the contents of the liquid dispensing container 1 and replenishes the empty container 4 with the contents, the refillable packaging bag 2 of the present invention is used.
In order to transfer the contents to an empty container using the refillable packaging bag 2 of the present invention, as shown in FIG. 1, the lower heat is left leaving the weakly bonded portion of the packaging bag 2 containing the contents. The seal portion is cut off, the upper heat seal portion of the packaging bag 2 is sandwiched between the notches 11 of the inner lid 10, put into the container 4, and the inner lid 10 is fitted into the container 4.
Next, the inner lid 10 is pressed by hand, a finger is put into a handle hole 26 formed in the upper part of the packaging bag 2 and pulled up to handle the packaging bag 2 by the notch 11 so that the packaging bag 2 can be handled. Even if the weakly bonded portion 25 formed in the lower part of the container is broken and the content 5 is viscous, it can be easily pushed out into the container 4 and transferred to the container without coming out.
[0015]
As shown in FIG. 4, the cut shape of the inner lid 10 is generally an arc shape, but is not limited to an arc shape, and may be a straight shape or a curved shape.
Further, the width of the notch 11 in the inner lid 10 needs a sufficient gap to sandwich the refillable packaging bag, but it is difficult to insert into the notch depending on the shape, material, thickness, size, etc. of the packaging bag. Since the degree is different, it should be selected according to the shape, material, thickness, size, etc. of the packaging bag.
The width of the cut 11 is usually preferably about 1 to 5 mm.
If the width of the notch 11 is 1 mm or less, it is difficult to squeeze the packaging bag 2 into the notch 11 and squeeze the contents, and the workability deteriorates, and it is necessary to reduce the thickness of the packaging bag. Causes a problem in strength.
In addition, when the width of the cut 11 is 5 mm or more, the workability is improved, but the content cannot be sufficiently squeezed, the amount of the content remaining in the packaging bag increases, and the original purpose cannot be achieved.
[0016]
As shown in FIG. 2, the refill packaging bag is generally a gusset bag in view of the display effect and the like. Further, the gusset bag is a packaging form suitable for the purpose of the present invention because a large amount of content can be obtained even with a relatively small packaging material width.
However, in addition to the gusset bag, a four-sided seal bag, a three-sided seal bag with a palm joint, or a bag in which a tubular film produced by an inflation method is vertically sealed can be used.
[0017]
The refill gusset bag of the present invention has a shape as shown in FIG.
FIG. 5A is a perspective view seen from the front side, and FIG. 5B is a perspective view seen from the back side. 5C is a plan view on the front side, FIG. 5D is a plan view on the back side, and FIG. 5E is a cross-sectional view taken along line XX in FIG. 5D.
As shown in FIGS. 5C and 5D, a weak adhesive portion 25, a lower heat seal portion 23, and a V notch 27 are provided at the lower portion of the gusset bag.
Further, an upper seal portion 24 and a handle hole 26 are provided in the upper portion of the gusset bag.
[0018]
The refill packaging bag of the present invention is produced as follows.
First, using a packaging material suitable for the contents, a laminate film that can be heat-sealed between the inner surfaces is prepared, and the inner surface of the laminate film is a portion that becomes a weak seal when used as a packaging bag, that is, a weak adhesive application portion. As shown in FIG. 6A, a weak adhesive is applied to 25a.
As shown in FIG. 6 (a), the weak adhesive is usually applied to the entire portion to be a weak adhesive portion, but as shown in FIG. 6 (b), the weak adhesive is applied by printing, In some cases, a partial heat seal portion 23a for allowing the inner surfaces to be heat sealed can be left.
As described above, by forming the heat seal portion 23a in the weakly bonded portion, it is possible to adjust the adhesive strength of the weakly bonded portion.
[0019]
Next, as shown in FIG. 6 (a), the inner surfaces of the laminate film are heat-sealed by jointing to form a back pasting portion 22, and then, as shown in FIG. 6 (c), both sides Is folded to form the folded portion 28, and the weak adhesive portion 25 and the lower heat seal portion 23 are formed to form a gusset bag.
Furthermore, as shown to Fig.7 (a), while forming V notch 27, the hole 26 for handles is formed, and the packaging bag 2 for refilling is produced.
The handle hole may be provided by punching after filling the packaging bag with the contents and forming the upper heat seal portion.
[0020]
The seal strength of the weakly bonded portion 25 can be used in the range of 200 to 900 g / 15 mm width when measured in accordance with JIS-Z-1707, but is preferably 300 to 500 g / 15 mm width.
If the seal strength is less than 200 g / 15 mm width, the weakly bonded part is broken during the filling operation of the contents or at the distribution stage, and the original purpose cannot be achieved.
On the other hand, when the width is larger than 900 g / 15 mm, damage during production or distribution is eliminated, but it is difficult to break during refilling work, and refilling work becomes difficult.
A well-known thing can be used as a weak adhesive agent for obtaining the said weak adhesive strength.
The amount of weak adhesive applied is 0.1 to 5.0 g / m. ² Is preferred.
[0021]
If a laminate film is produced using a uniaxially stretched film as a packaging material for a refill packaging bag and a packaging material that is easy to tear in the lateral direction is selected, it can be easily torn by hand without providing a V-notch. is there.
The refill packaging bag 2 is filled with contents such as shampoo and detergent, and then the upper part is heat sealed immediately to produce a refill gusset bag product as shown in FIG.
[0022]
Next, the case where refilling is performed on the liquid dispensing container using the refill packaging bag will be described.
First, as shown to Fig.8 (a), the lower heat seal part 23 is cut out from the packaging bag 2 containing the content using the V notch 27. FIG. In this case, as shown in FIG. 8 (b), the weak adhesive portion 25 remains, so that the content does not leak from the packaging bag 2.
As shown in FIG. 1, the packaging bag 2 from which the lower heat seal portion 23 is cut is placed in a container 4, and the upper heat seal portion 24 of the packaging bag 2 is placed in the inner lid 10 shown in FIG. At the same time, the skirt portion 17 is used to fit into the container 4.
Next, when the inner lid 10 is pressed by hand, a finger is put into the handle hole 26 provided in the upper heat seal portion 24 of the packaging bag 2 and pulled up, the packaging bag 2 containing the contents is cut into the notch 11. Since it is handled by the gap, the lower end of the weak seal portion 25 is broken and the content 5 is squeezed out into the container 4 by the pressure of the content, as shown in FIG.
[0023]
Further, when the packaging bag 2 is pulled up, as shown in FIG. 8 (d), the weak seal portion 25 is largely broken, the contents 5 flow into the container, and the lower end of the packaging bag 2 is moved to the inner lid 10. When pulled up to the position of the notch 11, the packaging bag 2 is handled by the notch 11, and the content 5 is squeezed out into the container 4, and hardly remains in the packaging bag 2.
Since the packaging bag 2 that has been squeezed out of the contents and has almost no residue has an extremely small volume when rolled up, it is possible to reduce the amount of dust and to help solve the packaging waste problem.
[0024]
The material of the packaging bag should be easy to insert into the notch of the handling inner lid, and to be slippery when pulling up the notch gap by hand to squeeze out the contents.
Therefore, there is flexibility, and the surface of the packaging bag is required to be made of a material that is slippery with the inner lid.
There are various types of packaging materials having the above aptitudes. For example, the following laminated films are preferable.
(Surface) ON / LLDPE (inner surface, the same shall apply hereinafter), ON / uniaxially drawn PE / LLDPE, PET / ON / EVA, ON / EVA, ON / LDPE, etc.
The above symbols indicate the following resins.
・ ON: Biaxially stretched nylon
・ LLDPE: Linear low density polyethylene
・ PE: Polyethylene
・ PET: Polyethylene terephthalate
EVA: ethylene-vinyl acetate copolymer
・ LDPE: Low density polyethylene

【The invention's effect】
As described above, the easily refillable packaging bag of the present invention is used as a packaging bag for refilling a liquid dispensing container.
The refillable packaging bag of the present invention uses the notch provided in the inner lid of the liquid dispensing container to handle the packaging bag, thereby destroying the weakly bonded portion formed on the packaging bag and removing the contents. The container is squeezed out to replenish the contents of the empty container.
For this reason, it is not necessary to squeeze the contents by hand when refilling, even for viscous contents such as shampoos and concentrated liquid detergents, so that the contents are almost not put into the packaging bag without leaving the contents outside. It can be easily transferred to the container without leaving.
[0039]
In addition, since the easy-refillable packaging bag of the present invention is provided with a normal heat seal part on the outside of the weakly bonded part, the trouble that the seal part is damaged during production or distribution and the contents leak is prevented. .
When refilling, remove this heat-sealed part using a V-notch, leave only the weakly bonded part, set the packaging bag in the notch of the inner lid, and use the handle hole provided on the top of the packaging bag. Since the packaging bag is pulled up, the contents can be easily squeezed out without requiring great force and without dirtying the hands.
And since the container of a liquid extraction container can be used repeatedly and the packaging bag discarded is comprised from a soft packaging material, a volume becomes extremely small and reduction of garbage can be aimed at.
Therefore, it can be used for solving the problem of waste pollution caused by disposable containers, which is a big social problem.
