BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid container made of paper, such as shampoo and conditioner, into which a certain amount of contents is to be used and has a slanted top. The pump dispenser can be installed so that the spout faces the ceiling.

[0002]

2. Description of the Related Art Conventionally, as a large container such as a shampoo or a rinse, a synthetic resin bottle provided with a pump dispenser type stopper is generally used. On the other hand, using a pump dispenser type plug for the liquid container made of paper means that most of the liquid containers made of paper have an inclined top shape due to good workability of assembly and good sealing performance. Therefore, it is not possible to use a pump dispenser that moves up and down with a normal spout, and paper is weaker than synthetic resin, so there is a problem that the container will bend due to vertical movement of the pump. It was

[0003]

However, if a paper liquid container can be equipped with a pump dispenser, it is inevitable that the applicable range of the paper liquid container will be expanded. It is significant to provide a wide range of paper liquid containers that can be easily disposed of. Therefore, the present invention solves the above-mentioned problems and allows a pump dispenser, which has been conventionally usable only for a synthetic resin container, to be attached to a paper liquid container, thereby expanding the range of application of the paper liquid container. Is an issue.

[0004]

In order to solve the above problems, the present invention provides the following paper liquid container. That is, in a paper liquid container having a spout on the top inclined surface, the spout comprises a flange portion, a mouth neck portion, and a cylindrical portion, the flange portion is provided in parallel to the top inclined surface, the cylindrical portion Is a liquid container made of paper, which is provided parallel to the longitudinal axis of the container through the mouth and neck.

Further, in a paper liquid container having a spout on the inclined surface of the top, the spout is parallel to the longitudinal axis of the container through a flange portion provided parallel to the inclined surface of the top and a neck portion. A paper tube equipped with a pump dispenser equipped with a support plate at the lower end of the tube, and a tube having a length reaching the bottom surface of the container and having a suction opening on the lower side surface. A liquid container.

[0006]

According to the present invention, since the cylindrical portion is provided in parallel with the longitudinal axis of the container through the mouth and neck portion, the spout can be directed straight upward, which allows it to move up and down. An athletic pump dispenser can be fitted. Further, since the pump dispenser has a length reaching the bottom of the container, has a suction port on the lower side surface, and includes a tube having a support plate at the lower end,
It is possible to prevent vibration generated when the pump dispenser moves up and down by the support plate, prevent the vibration from being concentrated on the mounting portion of the dispenser, and prevent the container from bending.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a paper liquid container of the present invention. The spout 1 is composed of a flange portion 2 provided in parallel with the top inclined surface 20a and a cylindrical portion 4 provided in parallel with the longitudinal axis of the container through the mouth / neck portion 3. A paper liquid container 20
It is fitted into the hole 21 on the top inclined surface 20a of the.

In this embodiment, the mouth / neck portion 3 is formed so as to straddle both the outer side and the inner side of the container with the flange portion 2 as a boundary, and the protrusion to the outside of the container is reduced. Even if the length of the inclined surface is short, the upper end of the spout will not protrude beyond the top of the container. If the upper end of the spout is higher than the top of the container, it may hinder work and transportation. However, the shape is not necessarily limited to this, and as another embodiment, as shown in FIG. 2, the mouth / neck portion 3 may entirely extend outside the container. Since the protrusion is limited to one side when the mouth-neck portion is entirely outside the container, there is an effect that workability is good when the container is assembled.

Further, in this embodiment, the flange portion 2 is formed so as to project to the outside of the container, and the hole 21 of the container is assembled at the time of assembly.
It is designed to be installed from the outside of the
It may be mounted from the inside of the hole 21 of the container so that it comes inside the container.

The spout 1 can be molded by injection molding.

FIG. 3 shows a state in which a pump dispenser is attached to the paper liquid container. Fit the spout 1 into the hole 21 of the liquid container 20 made of paper, and further add the pump dispenser 5
The pump dispenser 5 includes a pump portion, a valve cylinder portion, a tube 8 and a support plate 9. (The pump portion and the valve cylinder portion are not particularly different from general ones, and therefore description thereof will be omitted. ) The tube 8 has a length reaching the bottom of the container, a suction port 10 for sucking the liquid is provided on the lower side surface, and a disc-shaped support plate 9 is inserted at the lower end. Since the support plate 9 at the lower end of the pump dispenser 5 supports the vibration generated by the vertical movement of the pump, even if the pump is moved up and down, the top sloping surface does not bend accordingly.

FIG. 4 is an enlarged view of the support plate 9. In the present embodiment, the support plate 9 is composed of a disc-shaped bottom plate 9a and an insertion member 9b, and the insertion member 9b has a cross shape matching the inner diameter of the tube 8 so as to be inserted and fixed in the tube 8. . Since it is cruciform, it is in contact with the tube at four points, and is more securely fixed than, for example, the one-letter type.

By inserting the insertion member 9b of the support plate 9 into the lower end of the tube 8 and moving the pump up and down, the liquid moves upward through the suction port 10 through the insertion member 9b. .

As a method of providing the support plate at the lower end of the tube, in addition to the method of forming the tube and the support plate separately and inserting the support plate into the tube as in this embodiment, the tube and the support plate are integrated. Although a method of forming the tube is also conceivable, it is easier to mold the tube separately, which is suitable for mass production.

[0015]

As described above, according to the present invention, it is possible to mount the pump dispenser because the spout is directed toward the ceiling, even though the pump dispenser is fitted on the inclined surface of the top. It becomes possible to pour out a fixed amount of liquid in the liquid container. Further, since the pump dispenser is provided with a tube having a length reaching the bottom of the container and having a suction port on the lower side surface and a supporting plate at the lower end, vibrations that occur during vertical movement of the pump dispenser are supported by the supporting plate. It is possible to prevent this vibration from concentrating on the container body (near the spout) and prevent the container from bending.
