Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an object having fluidity such as a liquid or a viscous substance,
Particularly, the present invention relates to a container for pouring a liquid having a relatively high viscosity, for example, a creamy shampoo or a rinse, and pouring the liquid to the outside, and particularly storing the liquid in an easily deformable inner container, The present invention relates to a fluid pouring container in which the inner container is housed in an outer container that is not easily deformed, and the fluid is taken out of the container by a pump-type fluid pouring means attached to the mouth of the container.

(Prior Art) Conventionally, an inner container has an inner / outer double structure of an outer container that is difficult to deform and an inner container that is easily deformable, and a pump-type fluid discharge device attached to a container mouth is operated to operate the inner container. A fluid pouring container for pouring the fluid stored in the outside to deform the inner container by introducing atmospheric pressure between the inner and outer containers according to the pouring of the fluid is known, for example, , Japanese Patent Publication No. 55-3232 and Japanese Utility Model Publication No. 62-62676.

Such a double-structured pour-out container has the drawback that the single-plyed container up to that point, that is, the content flows out from the air inflow hole provided for inflowing air according to the decrease in the amount of fluid in the container. Proposed and developed to prevent the coming.

By the way, as shown in FIGS. 7 to 9, the inner container (1) used for such a double-structured pour-out container is formed by folding one sheet or stacking two sheets on the periphery (2). ) Is a flat bag-like container, and when the contents are not filled, it is generally a single flat container. When the contents are filled, as shown in FIG. 8, the central part swells in the direction orthogonal to the flat sheet surface at the arrow (3). Further, as the inner container is taken out from the mouth portion (4) formed at the center of the upper part of the inner container (1), it contracts in the direction opposite to the arrow (3) as shown by the arrow (5) in FIG. Will come.

The contraction due to the removal of the contents does not occur uniformly over the entire container, and the contraction of the central portion becomes faster,
As shown in the figure, the mouth often tended to be sealed with the contents left behind on the side (6). This tendency becomes more remarkable as the sheet material forming the inner container is softer and more flexible. Therefore, it is possible to form the sheet material with a relatively rigid sheet material,
Since this may make it difficult to store the inner container in the outer container, it was not possible to completely eliminate the tendency of the contents to remain on the side portions.

(Problem to be Solved by the Invention) This invention aims to prevent the contents from remaining by shrinking the container in four directions orthogonal to each other by forming the inner container into a special shape. Is.

(Means for Solving the Problems) In order to solve the above problems, the means adopted by the present invention are
Including an outer container that is difficult to deform and an easily deformable inner container,
A fluid pouring container in which a liquid pouring means sealed at the mouth of the inner container is attached to the container mouth, and the inner container (11) has four substantially triangular shapes extending in mutually orthogonal directions. The folding parts (19a, 19b, 19c, 19d) communicate with each other at the center,
It consists of a bag-shaped container having a shape in which the right-angled portions of the folding parts (19) adjacent to each other are placed upside down.
9) is folded in four directions orthogonal to each other and has a flat cross-shaped contracted shape.

(Embodiment) A preferred embodiment of the present invention will be described in detail below with reference to the drawings. In the figure, (10) is an outer container that is difficult to deform, and is preferably made of a relatively hard synthetic resin.
(11) is an inner container which is housed in the outer container (10) and is easily deformable, and has a flexible bag shape.

The mouth (12) of the outer container (10) is provided with a pump-type fluid pouring means (13) as conventionally known, and a holding cylinder (14) for holding the fluid pouring means (13). The mouth (15) of the inner container (11) is hermetically attached to the inner container (11) and is accommodated in the outer container (10) in a suspended state.

The fluid pouring means (13) includes a holding cylinder (14) fitted into the mouth (12) of the outer container (10) and a mounting cap screwed to the outer peripheral surface of the mouth (12). The flange (17) of the fluid pouring means (13) is sandwiched and held by (16), and when removing the mounting cap (16), the fluid pouring means (13) can be easily pulled out of the container. Can be done. Therefore, the fluid can be filled from the holding cylinder (14) into the inner container (11) before inserting the fluid pouring means (13), and the filling of the fluid can be performed by a mass production method. Can be done.

A pouring pipe (18) extending toward the inside of the inner container (11) is connected to the inner end of the fluid pouring means (13).

As described above, since the pouring pipe (18) has a large number of openings on the side surface and the bottom surface, the inner container (11) is deformed by pouring out the contents as shown in FIGS. Even if the bottom surface or side surface of the pouring pipe (18) is partially blocked, the contents can be sucked through the openings of other parts without hindrance, and pouring may become impossible or difficult. Disappears.

The inner container (11) has four substantially triangular folds (19a to 19d) extending in directions orthogonal to each other, which communicate with each other at the center, and folds (19) adjacent to each other. Has a shape in which the right-angled portions are positioned upside down. A single sheet is folded to form such a shape, and the periphery is sealed to form a bag-shaped container. When the inner container (11) has no contents, the inner container (11) extends in four orthogonal directions with the folded portion (19) folded, and contracts so that the planar shape is a cross shape as shown in FIG. Exhibit a shape. The central part of the upper part of the inner container (11) is left unsealed and is formed in the mouth (15), and the holding cylinder (14) is inserted into the mouth (15) to close the mouth (15). The outer peripheral surface of the holding cylinder (14) is closely contacted and joined.

When the fluid is filled, as shown in FIGS. 3 and 5, the folding parts (19) are expanded, and the inner container (11) has a substantially triangular pyramid shape.
It swells into a stacked shape. With the pouring of the contents, 4
One of the folding parts (19) contracts from four directions and returns to a cross-shaped folded shape as shown in FIGS.

(Operation) As described above, the inner container (11) is 4
Since it contracts from the direction and returns to a cross-shaped folded shape,
There is no risk of the contents remaining in the folding part (19).

(Effect of the Invention) According to this invention, it is possible to pour all the contents to the outside without the contents remaining in the inner container.
