[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 packaging bag for refilling into the container with the spout, the container with the spout is improved by providing an inner lid having a cut in the container with the spout.
[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 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, the present invention can easily extrude even the viscous contents by providing a notch for squeezing out the contents of the refillable packaging bag in the inner lid of the liquid dispensing container. It can be easily transferred to a container without leaving.
[0006]
[Means for Solving the Problems]
The above problems can be solved by the following present invention.
That is, in the liquid dispensing container having a structure in which the dispenser, the inner lid, and the cup-shaped container are separable, the opening of the container has a wide opening and is fitted to the wide opening. An inner lid is provided, and the inner lid has a plate-like base portion provided with a hole for inserting the suction pipe of the dispenser at the center thereof, and a cylindrical shape is formed on the upper surface around the hole of the base portion. Is provided on the peripheral edge of the base, and a handling cut for squeezing out the liquid in the packaging bag is formed in an arc shape, a curved shape, and a straight line from the peripheral edge portion to the inner side. And is provided so that the cut width is 1 to 5 mm, and the both sides of the cut are provided with an outer thick part and an inner thick part with a thickened base. Further, the portion of the bottom surface of the base except the start position of the notch is Vessel skirt for better fit to the opening of liquid dispensing in a container closure having a squeezing function, characterized by being formed by vertically of.
[0007]
Further, the refill packaging bag is made of a flexible material, has a hole that allows a finger of a hand to enter the upper seal portion, and forms a weak adhesive portion on the upper portion of the lower seal portion. It was decided to use a packaging bag having a V notch in the middle.
Therefore, at the time of refilling, after removing the lower seal part leaving at least a part of the weakly bonded part using the V notch of the refillable packaging bag, the upper seal part of the packaging bag is cut into the inner lid. By pulling up and pulling up the packaging bag, the weakly bonded portion can be broken, and the contents can be easily squeezed out, and the remaining amount of the contents can be extremely reduced.

[0010]
The present invention relates to an inner lid that constitutes a liquid dispensing container, and the liquid dispensing container 1 includes an extractor 3, a container 4, and an inner lid 10 as shown in FIG.
In addition, the thing with the same structure as the conventional thing was used for the extraction device 3.
[0011]
As shown in FIG. 1B, 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.
In addition, 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 provided on the dispenser 3, and the contents of the container 4 and the dispenser 3 are integrated. Prevents leakage.
Furthermore, the inner lid 10 of the present invention is fitted inside the opening of the container 4 to constitute a liquid dispenser 1 as shown in FIG.
Moreover, as shown in FIG. 3, the refillable packaging bag 2 used for the liquid dispenser 1 was a gusset bag provided with a handle hole 26 in the upper part.
[0012]
As shown in FIGS. 1A and 2, the inner lid 10 has a cylindrical upright portion 15 at the center of the base portion 16. A refillable packaging bag is sandwiched around the base portion, and the packaging bag is A cut 11 for handling is provided.
Further, an outer thick portion 12 and an inner thick portion 13 are formed on both sides of the cut 11 as shown in FIG.
[0013]
Further, as shown in FIGS. 5A and 5B, a stopper 18 for positioning the packaging bag is provided on the back side of the inner lid 10 when the skirt portion 17 and the refilling packaging bag are inserted. Yes.
The inner lid 10 has a shape as shown in FIGS. 2 and 5. FIG. 2A is a plan view on the front side, and FIG. 2B is a cross-sectional view taken along line XX in FIG. FIG. 2C is a cross-sectional view taken along line YY in FIG.
Fig.5 (a) is a top view of a back side, FIG.5 (b) is sectional drawing in ZZ of Fig.5 (a).
[0014]
That is, the front side of the inner lid 10 is formed with a cylindrical upright portion 15 in the center of the base portion 16, and the suction pipe 9 of the dispenser 3 shown in FIG. It is supposed to be inserted.
Also, a skirt portion 17 is provided on the back side of the inner lid 10 so as to be fitted into the wide-mouth opening of the container.
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 3, the liquid dispenser 1 is configured by integrating the dispenser 3 and the container 4.
[0015]
Moreover, the notch 11 is provided in the peripheral part of the inner cover 10, and this notch 11 moves the liquid content 5 of the refillable packaging bag 2 to the empty container 4 as shown in FIG. It is used to change.
That is, when the contents of the liquid dispensing container are not consumed, the inner lid 10 of the present invention is used when the empty container 4 is filled with the contents from the refill packaging bag 2.
[0016]
As shown in FIG. 4, the upper heat seal portion 24 of the packaging bag 2 containing the contents is sandwiched in the notch 11 of the inner lid 10, and fingers are put into the handle holes 26 formed in the upper portion of the packaging bag 2. When the contents are squeezed out and the contents are squeezed out, the weakly bonded portion formed at the bottom of the packaging bag 2 is broken, and even when the contents 5 are viscous, they can be easily pushed out into the container 4 without coming out. Can be easily transferred to a container.
Furthermore, the outer thick part 12 and the inner thick part 13 were formed on both sides of the notch 11 of the inner lid 10 to prevent the strength from being lowered due to the formation of the notch 11.
Therefore, even if the notch 11 is formed to about half the circumference of the inner lid 10, the strength for handling the packaging bag 2 and squeezing out the contents was obtained.
[0017]
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.
[0018]
As shown in FIG. 2 (a), the shape of the incision in the inner lid is generally an arc shape, but is not limited to an arc shape, as shown in FIGS. 6 (a) to (c). Alternatively, a curved shape can be used.
As shown in FIG. 6 (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.6 (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. 6B or an arc in terms of workability when squeezing the shape of the packaging bag and the contents.
[0019]
Further, as shown in FIGS. 1A, 5A, and 5B, a skirt portion 17 is provided on the back side of the inner lid 10 in order to improve the fit between the inner lid 10 and the container 2. Formed.
As shown in FIG. 5A, 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 reinforce strength reduction caused by the formation of the inner lid cut.
[0020]
Therefore, as shown in FIG. 5A, as many skirt portions 17 as possible should be formed in the outer portion where the cuts 11 are formed.
However, if the formation range of the skirt portion 17 is too large, it becomes difficult to insert the packaging bag 2 into the cut 11 and workability is deteriorated.
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.
[0021]
Further, as shown in FIG. 5A, a stopper 18 is formed at the end of the cut 11 on the back side of the inner lid 10.
By forming the stopper 18, when the packaging bag 2 is sandwiched between the cuts 11, the positioning of the packaging bag 2 is ensured and the strength of the inner lid is also reinforced.
[0022]
The inner lid 11 for handling the refill packaging bag is usually formed by injection molding. The inner lid needs to withstand repeated handling 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 4 and the dispenser 3 constituting the liquid dispensing container 1 are also formed by injection molding, and the same material as that of the inner lid 10 is used.
[0023]
Next, 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.
[0024]
As shown in FIG. 7A, the refill gusset bag is provided with a weak adhesive portion 25, a lower heat seal portion 23, and a V-notch 27 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.
[0025]
Next, the case where the contents are refilled in the liquid dispensing container using the refill packaging bag will be described.
First, as shown to Fig.7 (a), the lower heat seal part 23 is cut out from the packaging bag 2 containing the content using the V notch 27. FIG. Thus, even if the lower heat seal portion 23 is cut off, the weak seal portion 25 remains in the packaging bag 2 as shown in FIG. .
[0026]
As shown in FIG. 4, the packaging bag 2 from which the lower heat seal portion 23 has been cut is removed from the liquid dispensing container 1, removed from the dispenser 3 and the inner lid 10, and placed in an empty container 4. Then, the upper seal portion 24 of the packaging bag 2 is sandwiched between the notches 11 of the inner lid 10, and the inner lid 10 is fitted into the container 4.
When a finger is put into the handle hole 26 provided in the upper heat seal part 24 of the packaging bag 2 and the packaging bag 2 is pulled up while holding the inner lid 10 with the other hand, the packaging bag 2 containing the contents Therefore, due to the pressure of the content, the lower end of the weak seal portion 25 is broken and the content 5 is squeezed out into the container 4 as shown in FIG.
[0027]
Further, when the packaging bag 2 is pulled up, as shown in FIG. 7 (d), the weak seal portion 25 is largely broken, the contents 5 flow into the container, and then the lower end of the packaging bag 2 is moved into the middle. When pulled up to the position of the lid 10, the packaging bag 2 is handled 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 5 have been squeezed out has almost no remaining contents, and its volume becomes extremely small when rolled up, which leads to a reduction in the amount of dust and helps to solve the packaging waste problem.
[0028]
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 has an inner lid cut and good sliding properties.
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
【Example】
Hereinafter, the present invention will be described in more detail based on examples with reference to the drawings.
Example 1
As shown in FIG. 1, the liquid dispensing container 1 includes a dispenser 3, a container 4, and an inner lid 10. The dispenser 3, the container 4 and the inner lid 10 constituting the liquid dispensing container were produced by injection molding of polypropylene (hereinafter referred to as PP).
The container 4 had a diameter of 70 mm, a bottom inner diameter of 64 mm, and a height of 150 mm so that 500 ml of contents could be contained. And the screw was formed in the outer side of the container upper part, and it was made to seal with the screw lid 6 of the extractor 3, and screw fastening.
Moreover, the extractor 3 produced each component using a well-known technique, and comprised the extractor 3 combining these components. The lid of the dispenser 3 was a screw lid 6 for screwing the container 4 as described above.
[0030]
Next, the inner lid 10 having the following dimensions was manufactured by injection molding of PP so as to fit into the container 4.
The shape is as shown in FIGS. 2 and 5, the outer diameter of the base 16 having a thickness of 2 mm is set to 85 mm, and a cylindrical upright portion 15 having a height of 20 mm and a thickness of 2 mm is formed at the center thereof. The part 15 had an outer diameter of 24 mm and a hole diameter of 20 mm.
[0031]
Further, as shown in FIGS. 2A and 5A, the inner lid 10 is formed with an arc-shaped cut 11 having a width of 1.5 mm and a length of 85 mm along the circumference. An outer thick part 12 and an inner thick part 13 having a thickness of 2 mm were formed on both sides of the surface.
Furthermore, on the back side of the inner lid, as shown in FIGS. 5A and 5B, a skirt portion 17 having a thickness of 2 mm and a height of 12 mm and a thickness of 2 mm, a height of 12 mm and a length are provided along the circumference. A 20 mm stopper 18 was formed.
As shown in FIG. 5A, a part of the skirt portion 17 is cut in the vicinity of the entrance of the notch 11, and the interval between the cut portions is set to 35 mm.
[0032]
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.
[0033]
Next, a gusset bag was produced with the LLDPE surface of the base material facing inward, and 500 ml of liquid shampoo was filled therein to produce a refillable packaging bag 2 as shown in FIG.
As a result of transferring the refillable packaging bag containing the liquid shampoo to the container using the inner lid 10, the remaining amount of the packaging bag is very small without getting hands dirty or spilling the contents. There were few.
[0034]
That is, as shown in FIG. 7A, using the V-cut 27 of the packaging bag 2 containing the liquid shampoo, the tearing side seal portion 23 is removed laterally, and the state as shown in FIG. To do.
Next, as shown in FIG. 4, 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 and the notch 11 of the inner lid 10, and the container 4 of the liquid dispensing container 1 is placed. Put in.
[0035]
When the finger is put into the handle hole 26 of the packaging bag 2 and the inner lid 10 is pressed with the other hand and pulled up, the contents of the packaging bag 2 are pushed downward, and the pressure causes the FIG. ), A portion of the weak seal portion 25 is broken and the contents 5 are squeezed out into the container 4.
Further, when the packaging bag 2 is pulled upward, the weak seal portion is largely broken as shown in FIG. 7 (d), and the contents 5 are pushed out into the container 4.
Subsequently, when the packaging bag 2 is pulled up and the lower end of the packaging bag 2 is pulled up to the notch 11 of the inner lid 10, the packaging bag 2 is handled by the gap of the notch 11, and the contents 5 are placed in the container 4. It was completely squeezed out and the refilling work was completed.
[0036]
As a result of the refilling operation, the packaging bag 2 was almost free of contents, and the operation could be easily completed without dirtying hands during the refilling operation.
Further, since the packaging bag 2 that has been refilled is made of a soft packaging material, the volume of the packaging bag 2 becomes extremely small by rounding, and the packaging waste can be reduced.
[0037]
(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 that the cut shape was as shown in FIG. 6B.
Moreover, the refill packaging bag produced the gusset bag similarly to Example 1, and filled this with 500 ml of liquid shampoos, and it was set as the refill packaging bag.
[0038]
As a result of transferring the refillable packaging bag containing the liquid shampoo to the container using the inner lid produced in Example 2, the contents were not spilled, and the packaging bag The residual amount was small and could be easily transferred.
[0039]
【The invention's effect】
As described above, the present invention provides a soft packaging material provided with a notch for squeezing out the refill packaging bag in the inner lid of the liquid dispensing container, and also provided with a weak adhesive portion at the bottom as the refill packaging bag. By using the packaging bag made of the above, when refilling, the refilling packaging bag can be handled using the cuts, so even a viscous content can be easily refilled into a 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.
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.
