BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for storing a refilling liquid. More specifically, the present invention relates to a refillable liquid storage container that can be transferred without remaining liquid.

[0002]

2. Description of the Related Art Conventionally, shampoos, body soaps,
2. Description of the Related Art Pump-type containers that discharge a suitable amount of liquid such as dishwashing detergent with a pump when used are often used. And in recent years,
Due to resource savings, even if the contents of the pump-type container are exhausted,
The container is refilled with a new liquid without discarding, that is, the contents are refilled and reused many times.

[0003] Various types of containers for storing the refilling liquid are known. As one of them, there has been known one in which a spout for discharging a liquid is constituted by a pipe. In other words, the periphery of two front and back synthetic resin films is sealed, and a part of the periphery is provided with a protruding pouring part in which a hard or semi-hard pipe is embedded between the two front and back synthetic resin films. Liquid storage containers have been proposed.

FIG. 3 shows an example of the conventional refillable liquid storage container, and is a front view showing a state where the liquid is filled and sealed. Reference numeral 1 denotes a sealing portion which seals the periphery of the refillable liquid storage container, which is indicated by oblique lines. Numeral 2 denotes a protrusion forming a pouring portion. The protruding pouring portion 2 has a semi-rigid or hard pipe 3 inserted between a front film and a back film,
It has a structure in which the entire protrusion-like pouring portion is bonded and the pipe 3 is embedded. Reference numeral 4 denotes a spout of the pipe 3. FIG. 4 is a cross-sectional view of the protruding spout 2 of FIG. 3 taken along line AA. The pipe 3 is fixed by bonding the front film 5 and the back film 6, and seal portions 7, 8 are present on both sides of the pipe 3 in a fin shape.

In order to transfer the liquid inside from the refillable liquid storage container of FIG. 3 to a pump type container, the location of the A-A line of the protruding pouring portion 2 of the refillable liquid storage container is determined by scissors. And cut off the tip 9 of the seal portion, and then the outlet 4 of the pipe 3
Is exposed, and then the protruding spout 2 is inserted into the mouth of the pump-type container with the fin-shaped seals 7 and 8 attached, and the refillable liquid storage container is tilted to pump the contents liquid into the pump-type container. Drained into containers.

[0006]

In the above-mentioned refilling liquid container, a semi-rigid or hard pipe 3 is inserted between the front film and the back film, and the entire protruding spout is adhered to the pipe. In order to prevent the outlet of the pipe 3 from being blocked by the seal part when the protrusion 3 is formed by embedding the pipe 3, the end 3 ′ of the pipe 3 should be aligned with the end of the seal part. Alternatively, it is necessary to protrude inward from the seal portion (protrude into the liquid storage portion). In many cases, the end 3 ′ of the pipe 3 is buried so as to protrude inward from the seal portion as shown in FIG. 3. In this case, the liquid inside the refillable liquid storage container is pumped. When the liquid is transferred to the container, the liquid remains between the end of the pipe and the sealing portion (portion a in FIG. 3), and there is a problem that the entire liquid inside cannot be transferred. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a refillable liquid storage container that can transfer all of the contents liquid.

[0007]

According to the present invention, the periphery of two front and back synthetic resin films is sealed, and a projected pouring portion is provided around the periphery thereof, and the pouring portion is formed of two front and back synthetic resin films. A refillable liquid storage container in which a semi-rigid or hard pipe is embedded between films, wherein the pipe has a hole in a side wall of a tip portion on a liquid storage portion side. It is. That is, the present invention, in the refilling liquid storage container as described above, provided with holes in the side wall of the tip portion of the embedded semi-rigid or hard pipe on the liquid storage portion side,
Therefore, when the end of the pipe is buried so as to protrude toward the liquid storage portion side, the content liquid flows out from the hole existing at the base of the pipe, and is transferred without remaining the content liquid. It is something that you get.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A refillable liquid container according to the present invention
The periphery of the two front and back synthetic resin films is sealed, and a projection-like pouring portion is provided around the periphery. In the pouring section, a semi-rigid or rigid pipe is embedded between two front and back synthetic resin films. FIG. 1 shows an example of a refillable liquid storage container of the present invention, and is a front view showing a state in which a liquid is filled and sealed. In FIG. 1, reference numeral 1 denotes a seal portion which seals the periphery of the refillable liquid storage container, which is indicated by oblique lines. Numeral 2 is a projection forming a pouring portion. The projecting pouring portion 2 has a semi-rigid or hard pipe 3 inserted between a front film and a back film, and seals around the pipe.
Then, the entirety of the protruding pouring portion 2 is bonded and the pipe 3 is embedded. Then, a hole 10 exists in the side wall of the root portion of the portion of the pipe 3 protruding toward the liquid storage portion. The cross section of the pipe 3 is shown for easy understanding.

[0009] The front and back two synthetic resin films include various materials commonly used in the art, such as biaxially oriented polypropylene film, biaxially oriented polyamide film, biaxially oriented polyester film, ethylene-vinyl alcohol copolymer film and the like. A composite film in which a film is used as a base material, and a olefin-based thermal adhesive resin such as low-density polyethylene, linear low-density polyethylene, ethylene-vinyl acetate copolymer, or polypropylene is laminated as a sealant layer on these base films Used. In this case, a plurality of the above-mentioned various films may be laminated on the substrate in order to enhance the protection of the contents, and further, an aluminum foil may be used.

In the present invention, the semi-rigid or rigid pipe buried in the protruding pouring portion is formed by molding medium density or high density polyethylene, polypropylene, polyvinyl chloride or the like. The length of the pipe is 10 to 30 mm. The outer and inner diameters of the pipe depend on the inner diameter of the mouth of the container to which the contents are to be transferred. For example, in the case of a refillable liquid storage container intended to be refilled with a general pump-type container having an inner diameter of about 20 mm in the mouth of the counterpart container, the inner diameter is preferably 6 to 15 mm. The pipe thickness is 0.5 ~
1.5 mm is preferred.

The semi-rigid or rigid pipe has holes in its side wall. The holes preferably extend over the entire circumference of the side wall. When the size of the hole is circular, the diameter is preferably about 2 to 5 mm. If the size of the hole is smaller than 2 mm, the outflow speed of the liquid becomes slow, and if it is larger than 5 mm, the strength of the pipe becomes small, and there is a possibility that the pipe may be broken during transportation, and both have problems. The shape of this hole may be another shape such as an ellipse. Further, it is preferable to provide about 2 to 8 holes. When the holes are provided, they may be arranged along the circumferential direction, or may be formed in a zigzag shape around the circumference. FIG. 2 is a perspective view of an example of a pipe provided with holes. 3 is a pipe and 10 is a hole. The hole 10 may be provided over the entire side wall of the pipe 3 as shown in FIG.
2B, it may be provided around about half of the side wall of the pipe 3, or as shown in FIG. 2C, it may be provided only around the side wall of the tip end of the pipe 3.

The front film 5 and the back film 6
In the case where the pipe 3 is inserted between them and the whole protruding spout is bonded and the pipe 3 is buried, there is no selectivity in the case of (A), but in the case of (B) and (C) In this case, the hole is buried so that the portion provided with the hole comes to the liquid storage unit side. That is, as shown in FIG. 1, at least one hole 10 is provided on the side wall of the root portion of the portion of the pipe 3 protruding toward the liquid storage portion. The holes in the pipe side wall other than the root portion are sealed with the front and back synthetic resin films.
When the refillable liquid storage container of the present invention is prepared using the above-described pipe, even if the end of the pipe protrudes from the seal end, the liquid inside flows out from the hole 10 at the base of the pipe. It can be transferred without leaving liquid inside.

[0013]

When the contents liquid is transferred to the pump-type container using the refillable liquid storage container of the present invention, the end of the pipe 3 protrudes inside the seal portion (projects into the liquid storage portion). However, the hole 1 in the side wall of the buried root of the pipe
Since the liquid flows out from 0, all the liquid in the container can be transferred without the liquid remaining in the container.
