Description

[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. In order to facilitate the refilling of the contents from the refill refill packaging bag into the container with the spout, the refill refill packaging bag and the refill refill packaging bag are improved.
[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 order to eliminate the waste pollution and economic disadvantages caused by the disposable containers, a partly sold product in which the contents are put in a refill bag is supplied.
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 the container has a small caliber, the transfer from the packaging bag to the container is cumbersome, and the contents are spilled out of the container at the time of refilling. There was a problem that the contents could not be sufficiently discharged and 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 containers, how to reduce the amount of garbage after use is important, as packaging / containers should be made as small as possible by eliminating extra parts as much as possible. It has become a challenge.
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, a notch for squeezing out the contents of the refill packaging bag is provided in the inner lid of the liquid dispensing container, and a weak adhesive portion is provided at the bottom of the refill packaging bag. By squeezing out the refill packaging bag using the notch, the weakly bonded portion is broken, and even the viscous contents can be easily pushed out, and easily transferred to the container without leaving the contents in the packaging bag .
[0006]

[0010]
As shown in FIG. 2, the present invention includes a liquid dispensing container 1 and a refilling packaging bag 2, and the liquid dispensing container 1 includes a dispenser 3 and a container 4 as shown in FIG. 1. And an inner lid 10.
In addition, the thing with the same structure as the conventional thing was used for the extraction device 3.
[0011]
As shown in FIG. 1, the container 4 of the liquid dispensing container 1 of the present invention has a wide opening so that the refillable packaging bag 2 can be easily placed in the container 4.
Moreover, the thread 7 is formed in the outer side of the opening part of the container 4, and the container 4 and the extractor 3 are integrated by screwing, and the leakage of the content is prevented.
Further, an inner lid 10 which is a feature of the present invention is fitted inside the opening of the container 4.
[0012]
As shown in FIG. 3 (a), the inner lid 10 has a cylindrical upright portion 15 in the center of the base portion 16, and is provided with a notch 11 for sandwiching a refillable packaging bag at the periphery of the base portion. A thick portion 12 (outside) and a thick portion 13 (inside) are provided on both sides of the cut 11.
Further, as shown in FIG. 3B, a skirt portion 17 and a stopper 18 when the refill packaging bag is inserted are provided on the back side of the inner lid 10.
The inner lid 10 has a shape as shown in FIG. 4, FIG. 4 (a) is a cross-sectional view taken along line YY of FIG. 3 (a), and FIG. ) Of FIG. 4 is a cross-sectional view taken along line XX, and FIG. 4C is a cross-sectional view taken along line ZZ of FIG.
[0013]
That is, the inner lid 10 has a cylindrical upright portion 15 formed in the center of the base portion on the front side, and the suction pipe 9 of the dispenser 3 shown in FIG. 1 is inserted into the hole 14 of the upright portion 15. It has come to be.
And the notch 11 for pinching the refillable packaging bag is provided in the peripheral part of the inner lid.
As shown in FIG. 1, the notch 11 is used to transfer the liquid content 5 of the refill packaging bag 2 to the container 4.
[0014]
As shown in FIG. 1, the upper part of the packaging bag 2 containing the contents is sandwiched between the notches 11 of the inner lid 10, the fingers are put into the handle holes formed in the upper part of the packaging bag 2, and the contents are pulled up. By squeezing out the object, the weakly bonded part formed at the lower part of the packaging bag 2 is broken, and even when the contents 5 are viscous, it can be easily pushed out into the container 4 and easily put into the container without coming out. It is transferred.
Furthermore, the thick portions 12 and 13 were formed on both sides of the notch 11 of the inner lid to prevent the strength from being lowered due to the formation of the notch 11. Therefore, the strength for narrowing down the packaging bag 2 was obtained even if the cuts were formed up to about half the circumference of the inner lid.
[0015]
In addition, the width of the notch in the inner lid needs to have a sufficient gap to sandwich the refill packaging bag, but depending on the shape, material, thickness, size, etc. of the packaging bag, the difficulty of insertion into the notch Since it is different, it should be selected according to the shape, material, thickness, size, etc. of the packaging bag.
Usually, about 1-5 mm is preferable. If the thickness is less than 1 mm, it is difficult to squeeze the contents of the packaging bag and squeeze out the contents, resulting in poor workability and a reduction in the thickness of the packaging bag, which causes a problem in strength.
On the other hand, when the thickness is 5 mm or more, the workability is improved, but the contents cannot be sufficiently squeezed, the amount of contents remaining in the packaging bag is increased, and the original purpose cannot be achieved.
[0016]
The shape of the incision in the inner lid is generally an arc as shown in FIG. 3 (a), but is not limited to an arc, but as shown in FIGS. 5 (a) to (c), Alternatively, a curved shape can be used.
As shown in FIG. 5 (a), when the cut is linear, workability is good, but the width of the packaging bag needs to be smaller than the arc, and the shape of the packaging bag is elongated, so that it is self-supporting. In some cases, this may be a problem.
Moreover, as shown in FIG.5 (c), when a curve part is increased, even if a wide packaging bag can be used, workability | operativity will worsen and a problem will arise.
Therefore, the shape of the cut is preferably a curved shape as shown in FIG. 5B or an arc in terms of workability when squeezing the shape of the packaging bag and the contents.
[0017]
Further, as shown in FIG. 3B and FIGS. 4A to 4C, in order to improve the fitting property when the inner lid 10 is fitted to the container 2, A skirt portion 17 was formed.
As shown in FIG. 3 (b), the skirt portion 17 is formed in most of the periphery except the first portion of the notch 11.
This skirt portion 17 is necessary for fitting into the container 2, but at the same time, it serves to prevent a decrease in strength caused by the formation of a cut in the inner lid.
[0018]
Therefore, as shown in FIG. 3B, the skirt portion 17 should be formed in the outer portion of the notch generated by the formation of the notch 11, and the outermost portion of the notch should be formed.
However, if the area where the skirt portion 17 is formed is too large, it becomes difficult to insert the packaging bag 2 into the cut 11, and workability deteriorates.
Therefore, the formation range of the skirt portion 17 is preferably around 3/4 to 4/5. However, the degree of difficulty of insertion into the cut differs depending on the shape, material, thickness, size, etc. of the packaging bag, and it may be possible to perform even outside the above range. Should be designed.
[0019]
Further, on the back side of the inner lid, as shown in FIG. 3B, a stopper 18 is formed at the end of the cut.
By forming the stopper, when the packaging bag 2 is cut 11 and sandwiched, the positioning of the packaging bag 2 is ensured and the strength of the inner lid is also reinforced.
[0020]
The inner lid for squeezing the refill packaging bag is usually formed by injection molding. The inner lid needs to withstand repeated ironing operations, and must have durability, impact resistance, water resistance, and the like. Polypropylene, polyethylene, polystyrene, polycarbonate, acrylic, ABS, etc. are used as the material. The
Further, the wide-mouth container and the dispenser constituting the liquid dispensing container are also formed by injection molding, and the same material as the inner lid is used.
[0021]
Next, as shown in FIG. 6A, gusset bags are generally used as refill packaging bags in terms of display effects and the like. Further, the gusset bag is a packaging form suitable for the object of the present invention because a large internal capacity 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.
[0022]
The refill gusset bag of the present invention has a shape as shown in FIG.
6A is a perspective view seen from the front side, and FIG. 6B is a perspective view seen from the back side. 6C is a plan view on the front side, FIG. 6D is a plan view on the back side, and FIG. 6E is a cross-sectional view taken along line XX in FIG. 6D.
As shown in FIGS. 6C and 6D, 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.
[0023]
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 laminate film is shown in FIG. As such, a weak adhesive is applied.
As shown in FIG. 7 (a), the weak adhesive is usually applied to the entire portion to be a weak adhesive portion, but as shown in FIG. 7 (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.
[0024]
Next, as shown in FIG. 7 (a), the inner surfaces of the laminate film are heat-sealed by jointing to form a back-sealed seal portion 22, and then both sides as shown in FIG. 7 (c). The side 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.8 (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.
[0025]
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 smaller 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.
[0026]
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 immediately after that, the upper part is heat sealed to produce a refill gusset bag product as shown in FIG.
[0027]
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.9 (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. 9B, the weak seal 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 has been cut is placed in a container 4 and sandwiched between notches in the ironing lid 10.
Next, when the 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 squeezed, so that the pressure of the contents As shown in FIG. 9C, the lower end of the weak seal portion 25 is broken and the contents 5 are squeezed out into the container 4.
[0028]
Furthermore, when the packaging bag 2 is pulled up, as shown in FIG. 9 (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 positioned at the position of the inner lid. When pulled up, the packaging bag 2 is squeezed by the notch 11 of the inner lid 10, and the contents 5 are completely squeezed out into the container 4.
The packaging bag 2 from which the contents have been squeezed out has almost no remaining contents, and its volume becomes extremely small when rolled up. This leads to a reduction in the amount of dust and helps to solve the packaging waste problem.
[0029]
The packaging bag must be easy to insert into the notch of the ironing inner lid and slip easily when the gap of the notch is pulled up by hand to squeeze out the contents.
Therefore, it is flexible, and the surface of the packaging bag is required to be made of a material that is slippery with the inner lid.
Although there are various types of packaging materials having the above-mentioned suitability, the following laminated film as an example is 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

As shown in FIG. 3B, a part of the skirt was cut in the vicinity of the entrance of the notch 11, and the interval between the cut portions was set to 35 mm.
[0033]
Moreover, the packaging bag for refilling was produced as follows.
First, a laminate film of ON 25 μm / LLDPE 40 μm (hereinafter simply referred to as a base material) is prepared by a dry lamination method, and this laminate film is cut into a size of 300 mm in width and 210 mm in length to form a weak seal portion on the LLDPE surface. A weak adhesive (“EOP varnish” manufactured by The Inktec Co., Ltd.) was applied, and the thickness of the weak adhesive layer after drying was 2 μm. Next, the base material was heat-sealed by laminating with the LLDPE surface facing inward to obtain a cylindrical shape as shown in FIG.
[0034]
As shown in FIG. 7 (c), both sides of the cylindrical object are folded to a width of 20 mm to form the folded portion 28, and then the weak adhesive application portion 25a is sealed to form the weak adhesive portion 25. Gusseted bags were made.
The weak seal portion 25 has a shape as shown in FIG. 7C, and is sealed at a position 10 mm above the lower end of the base material. The minimum width of the seal is 15 mm and the maximum width is 35 mm.
Moreover, when the intensity | strength of the weak seal part was measured based on JIS-Z-1707, the intensity | strength was 400 g / 15mm width.
Furthermore, the lower part of the weak seal part was heat sealed to form a lower heat seal part 23 having a width of 10 mm. The strength of the heat seal part was 3.2 kg / 15 mm width when measured in the same manner.
[0035]
Next, as shown in FIG. 8A, a V-cut for removing the lower seal portion 23 when opening the weakly bonded portion 25 at a position 5 mm above the upper end of the lower heat seal portion 23 of the gusset bag. 27 was formed.

[0037]
As a result of transferring the refillable packaging bag containing the liquid shampoo to the liquid dispensing container, the hands were not soiled, the contents were not spilled, and the remaining contents of the packaging bag were very small. .
That is, as shown in FIG. 9A, using the V-cut 27 of the packaging bag 2 containing the liquid shampoo, the tearing lower seal portion 23 is removed laterally, and the state as shown in FIG. To do.
[0038]
Next, as shown in FIG. 1, the packaging bag 2 from which the lower sealing portion 23 is removed is sandwiched between the upper sealing portion 24 of the packaging bag 2 in the notch 11 of the inner lid 10, and the container 4 of the liquid dispensing container 1 is placed. Put in.
When a finger is put into the handle hole 26 of the packaging bag 2, the inner lid is pressed with the other hand and pulled up, the contents of the packaging bag 2 are pushed downward, and the pressure causes FIG. 9 (c). As shown in FIG. 3, the weak seal portion 25 is partially broken to squeeze the contents 5 into the container 4. Further, when the packaging bag 2 is pulled upward, the weak seal portion is largely broken as shown in FIG. 9 (d), and the contents 5 are pushed out into the container 4.
Further, when the packaging bag 2 is pulled up and the lower end of the packaging bag 2 is pulled up to the notch of the inner lid, the contents are completely squeezed into the container 4 by the gap of the notch 11, The contents were almost gone and the transfer work was completed.
[0039]
(Example 2)
In the same manner as in Example 1, a dispenser 3 and a container 4 of a liquid dispensing container as shown in FIG.
The inner lid 10 was also the same as that of Example 1 except for the cut shape as shown in FIG. 5B.
Moreover, the repackaging packaging bag produced the pillow type gas-split packaging bag as follows using the same laminate film as Example 1. FIG.
First, the laminate film (base material) is cut to a size of 240 mm in width and 250 mm in length, and a weak adhesive layer is formed on the portion that becomes the weak seal portion of the LLDPE surface in the same manner as in Example 1, with the LLDPE surface facing inward. Then, heat sealing was carried out by gluing, and a cylindrical shape was obtained as shown in FIG.
[0040]
Next, as shown in FIG. 10 (b), the lower portion to which the weak adhesive is applied is sealed to form the weak adhesive portion 25, and then the lower portion of the weak adhesive portion is heat-sealed to form a lower portion having a width of 10 mm. A heat-sealed portion 23 was formed to produce a palm-wrapped packaging bag.
The shape of the weakly bonded portion 25 was as shown in FIG. 10B, and was sealed at a position 10 mm above the lower end of the base material. The minimum width of the seal was 15 mm and the maximum width was 35 mm. The strength of this weakly bonded part was 400 g / 15 mm width. The strength of the heat seal part was 3.0 kg / 15 mm width.
Further, as shown in FIG. 10 (c), a V-cut 27 and a handle hole 26 were provided in this joint-attached packaging bag in the same manner as in Example 1.
[0041]
The shampoo packaging bag is filled with 500 ml of liquid shampoo, and the upper part of the packaging bag 2 is heat-sealed with a width of 35 mm as shown in FIG. 2.

Further, the refill packaging bag 2 was hooked on a stick or hook using the handle hole 26 and displayed at the store, but there was no problem in strength.
[0042]
As a result of transferring the refillable packaging bag containing the liquid shampoo to the liquid dispensing container, the contents were not spilled, and the contents remained in the packaging bag, and could be easily transferred.
That is, similarly to Example 1, after removing the lower seal portion 23 using the V-cut 27 of the packaging bag 2 containing the liquid shampoo, the upper seal portion 24 of the packaging bag 2 is moved to the curve of the inner lid 10. It is inserted into the shaped cut 11 and put into the container 4 of the liquid dispensing container 1.
As in the first embodiment, when the finger is put into the handle hole 26 of the packaging bag 2 and the inner lid is pressed with the other hand and pulled up, the packaging bag 2 can be easily pulled up without great resistance. The weak seal portion 25 was broken and the content 5 was squeezed out into the container 4.
The packaging bag 2 had almost no residual content, and the transfer operation could be easily completed.
[0043]
【The invention's effect】
As described above, the present invention is provided with a notch for squeezing out the contents of the refill packaging bag in the inner lid of the liquid dispensing container, and a weak adhesive portion at the bottom of the refill packaging bag. When refilling, the packaging bag for refilling is squeezed out using the above-mentioned notch, whereby the weakly bonded portion of the packaging bag is broken, and even viscous contents can be easily pushed out into the container.
Therefore, even viscous contents such as shampoos and concentrated liquid detergents can be easily transferred to a container without being left outside during refilling and leaving almost no contents in the packaging bag.
[0044]
Further, since the refill packaging bag is provided with a normal heat seal part outside the weakly bonded part, troubles that are damaged during manufacture or distribution and the contents leak are 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.
