[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-container tube container, and more particularly, to a two-container which can store two kinds of liquids separately and can simultaneously pour out the two kinds of liquids. It relates to a tube container.

[0002]

[Prior art]

For example, liquid preparations such as hair dyes are used by mixing two liquids at the time of use, but when mixed and stored, they react with each other and lose their drag. Each liquid is stored in a container, and each liquid is poured into a third container during use.

However, storage in separate containers requires removing the cap and pouring out the liquid, which is troublesome, and one of the containers may be lost.

The present invention has been made in view of the above points, and can store and pour two liquids at the same time, and at the time of pour, can pour each liquid by another route and mix the two liquids at the spout. It is intended to propose an excellent two-pack tube container that does not generate.

[0005]

In order to solve the above-mentioned problems, the container according to the present invention comprises an outer container body 2 having a squeezable cylindrical body 6 and a mouth-and-neck portion 8 erected from a top end of the cylindrical body 6 via a shoulder 7; Torso 6
The inner container body 3 standing upright from the squeezable body 9 via the shoulder portion 10 and housed in the inner container body 3 is connected to each of the mouth and neck portions in such a manner that the liquid around the inner container body 3 can be filled. The upper ends of 8, 11 are fitted and fixed by the pouring member 4.
A first pouring tube portion 15 communicating from the center of the top wall 14 with the inside of the inner container body 3 via the first check valve 22 is erected, and the inside of the outer container body 2 is shifted from the eccentric position of the top wall 14. And a second discharge cylinder portion 18 which is in communication with the second check valve 23 and is shorter than the first discharge cylinder portion 15.

[0006]

When the body 6 of the outer container is squeezed, the liquid in the body 6 opens the second check valve 23 and is discharged from the second discharge cylinder 18.
At the same time, the inner container body 9 is also squeezed, and the liquid in the body 9 is opened from the first check valve 22 and discharged from the first dispensing cylinder 15. If the container body 1 is tilted so that the second pouring tube portion 18 is positioned downward, and the liquid is discharged, there is no danger that other liquids will come into contact with each other.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 3 show an embodiment of the present invention. In the drawings, reference numeral 1 denotes a two-part tube container. The container 1 includes an outer container body 2, an inner container body 3, a spout member 4, and a cap 5.

[0009] The outer container body 2 is constructed by erecting a mouth and neck portion 8 from a top end of a squeezable cylindrical body portion 6 via a shoulder portion 7.
Similarly, the inner container body 3 also has a mouth-and-neck portion 11 standing upright via a shoulder portion 10 from the upper end of the squeezable cylindrical body portion 9. The body part 9 and the mouth-neck part 11 of the inner container body 3 are formed smaller in diameter than the body part 6 and the mouth-neck part 8 of the outer container body, respectively.
Are configured so that they can be stored in the outer container body 2 with a predetermined space around them.

The outlet member 4 has a cylindrical shape in which a top wall 14 is extended from an upper edge of a peripheral wall 13 erected from a peripheral edge of a bottom wall 12. Inclined wall descending forward
The low top wall portion 14c is formed in a stepped shape extending through the 14b. In addition, a first pouring tube portion 15 is erected from the center of the top surface of the bottom wall 12 to the upper portion of the top wall 14 through the center portion of the top wall 14, and a through hole 16 is formed in the bottom wall 12 in the tube portion 15. Has been established. In addition, the first dispensing cylinder 15
A through hole 17 is also formed on the outer bottom wall 12 on the inner side of the peripheral wall 13, a lower end is opened in the low top wall portion 14 c at an eccentric position of the top wall 14, and the first discharging cylinder portion 15 is formed. A second pouring tube portion 18 having a lower height than the second pouring tube portion 18 is provided. In addition, a first fitting cylindrical portion 19 having a barb provided on the lower end edge of the inner surface is vertically provided below the peripheral edge of the bottom wall 12, and a second fitting cylindrical portion is provided from a lower central portion of the bottom wall 12.
20 are hanging. Further, the first and second surfaces on the lower surface of the bottom wall 12
At a predetermined position between the fitting tubular portions 19 and 20, a seal tubular portion 21 for fitting the inner periphery of the outer container body neck 8 in a liquid-tight manner is provided vertically.

The through holes 16 and 17 are provided with first and second check valves 22 and 23, respectively, so that the liquid flows upward from below the bottom wall 12.
That is, it is configured to flow unilaterally downstream from the upstream. The first check valve 22 is formed on the upper surface of the through hole 16 by a valve plate 22b connected to a part of the inner and lower ends of a cylindrical mounting base 22a having upper and lower end openings which are fitted to the inner and lower ends of the first discharging cylinder part 15 by a thin hinge portion. Is openably closed. The second check valve 23 has a through-hole 17 with a ring-shaped valve body 23a mounted on the bottom wall 12.
The upper surface is closed so that it can be opened and closed. In the present embodiment, as shown in FIG.
It is composed of members.

The outer container 2 is mounted by fitting the outer surface of the upper end of the outer container body neck 8 to the inner surface of the first fitting cylindrical portion 19 of the spout member 4 configured as described above. At this time, the seal tube portion 21 is
Fits liquid tight on the inner surface. Further, the inner container 3 is inserted through the lower end opening of the outer container body 6, and the mouth and neck portion 11 is inserted into the second container.
The inner container 3 is fitted to the inner surface of the fitting tube portion 20 in a liquid-tight manner. Then, after filling the liquid in each container body 6, 9,
The lower ends of the container body portions 6 and 9 are configured to be sealed flat.

The cap 5 has a screw tube 25 which is screwed from the center of the lower surface of the top wall 24 whose central portion is protruded into a cylindrical shape to the outer peripheral lower part of the neck 8 of the outer container body.
26 is attached vertically and detachably attached. Further, the upper end of the first discharging cylinder portion 15 can be stored in the raised portion.

In the figures, reference numerals 27 and 28 denote packings, respectively. All of the above members are formed of a synthetic resin.

[0015]

[Effect of the Invention] As described above, the container of the present invention has the above-described configuration, so that the inner container can be housed in the outer container and the two liquids can be stored together in a separated state. In addition, when the outer container body is squeezed at the time of pouring, the two liquids can be simultaneously poured out, so that the handling is convenient and there is no danger of losing one container unlike the conventional case.

[0016] Further, since a step is provided in each of the dispensing cylinders communicating with each of the inner and outer container bodies , one of the liquids is discharged when the liquid is discharged.
A reaction product is generated by adhering to the
There is no inconvenience such as remaining in the pouring hole.
