Description

[Detailed description of the invention] "Industrial application field" This invention relates to a double tube container that allows for the dispensing of, for example, two types of cream cosmetics of the same type or different colors. .

"Prior Art" A small tube container is enclosed within a large tube container, and a small tube container nozzle is inserted into the large tube container through a through hole formed in the shoulder of the large tube container. There is a known device in which the upper surface of the shoulder of a small tube container is fixed to the inner surface of the shoulder of a large tube container by protruding outward in line with the nozzle of the container (Japanese Utility Model Publication No. 42-9340).

``Problem to be solved by the invention'' In the conventional double tube container mentioned above, it is difficult to fix the upper surface of the shoulder of the small tube container to the inner surface of the shoulder of the large tube container, and on the other hand, storage can only be carried out from the tube container. It was difficult to pour things out.
In addition, the double tube container dispenses the contents by rolling up the body using a squeezing handle fixed to the lower end of the body, and is designed to maintain the rolled up state. This is possible only if the tube container is made of metal, and if it is made of synthetic resin, it will recover elastically, so outside air will be sucked into the tube container when the tube container recovers elastically.
As a result, the contents stored in the body are susceptible to oxidation and deterioration when exposed to the inhaled outside air.

The purpose of this proposal is to eliminate such drawbacks and simplify the structure.

"Means for Solving the Problems" A large tubular container body 1 made of synthetic resin has an inward flange 5 attached to the inner surface of the first neck part 4, and the outer peripheral part of the bottom wall is placed on the inward flange 5. The large-diameter cylindrical portion 7 with a bottom is watertightly fitted to the inner surface of the mouth and neck portion above the inward flange, and the legs are inserted from the lower surface of the bottom wall with a gap between the inner circumference and the inner circumferential surface of the inward flange. The cylinder 9 is suspended, and the inside of the large diameter cylinder part 7 is divided into left and right reservoir chambers 8, 8 by a partition wall, and one reservoir chamber and the inside of the leg tube 9 are connected to each other, and the other reservoir chamber is connected through the gap. The discharge path forming member 6 has a small through hole formed in the bottom wall to communicate with the inside of the large tube container body 1, and the second neck part 11 is fitted into the leg tube 9 to form the large tube container body 1. A small tube container body 10 made of synthetic resin vertically installed in the tube container body 1, and the left and right reservoir chambers 8,
A peripheral wall 13 is vertically installed from the outer periphery of the top wall 14 that closes the upper end surface of 8 to the outer surface of the first mouth and neck part, and
Spout holes 15, 15 are formed in the upper top wall portions of the two chambers, and cover plates 16, 16 having plugs 18, 18 tightly fitted into the spout holes 15, 15 are installed on the top wall. The cap 12 is placed on the upper surface of both the left and right halves of the top wall 14, and the outside of both lid plates are connected to the outer edges of both the left and right sides of the top wall 14 via hinges 17, 17, so that each lid plate can be opened and closed. Formed.

"Operation" When the two lid plates 16, 16 are both opened and the body 2 of the large tube container body 1 is squeezed, the body of the small tube container body 10 will also be squeezed. The contents stored in the tube container pass through the gap between the inner periphery of the inward flange 5 and the leg tube 9, and a small through hole bored in the bottom wall of the discharge path forming member 6 that closes the upper part of the gap. The contents stored in the small tube container enter the left and right reservoir chambers 8, 8 of the large-diameter cylindrical portion 7 through small through holes bored in the leg tube 9 and the upper bottom wall portion thereof, and then enter the left and right reservoir chambers 8, 8 of the large diameter tube portion 7, respectively. After filling the chambers, the liquid is poured out through spouts 15, 15 formed in the top wall 14 above both chambers. On the other hand, if only the contents stored in the tube container body are to be poured out, the body of the large tube container may be squeezed with only one lid plate 16 opened and the other lid plate 16 closed.

After dispensing, when the compression of the large tube container body 2 is released, the body 2 and the body of the small tube container 10 try to restore their elasticity, but the cream-like substance remains in the reservoir chambers 8, 8. Because it is filled with things,
Outside air is not sucked into the body until the creamy substance in the reservoir is sucked back and the small through hole in the bottom wall of the reservoir communicates with the spout hole 15, and therefore, during that time, the lid plate 16 is closed. By sealing the spout hole 15 with the plug 18, it is possible to completely prevent outside air from being drawn into the body.

``Example'' 1 is a large tube container made of synthetic resin, with a mouth and neck part 4 erected from the upper end of a body part 2 via a shoulder part 3, and an inward flange 5 is attached to the inside of the mouth and neck part. .

A discharge path forming member 6 is fitted into the mouth and neck. This member has a large diameter cylindrical part 7 standing up from the outer periphery of the bottom wall, a small diameter leg cylinder 9 hanging down from the lower surface of the bottom wall, and left and right reservoir chambers 8, 8 inside the large diameter cylindrical part 7 by partition walls. It is divided into two parts, and one side of the room is connected to the inside of the leg tube 9 through a small through hole provided in the bottom wall, and the other side has a small through hole drilled in the bottom wall part outside the upper part of the leg tube 9 inside the room. Then, as shown in FIG. 1, the outer periphery of the bottom wall is placed on the inward flange 5, and the large diameter cylindrical portion 7 is fitted watertightly into the inner surface of the mouth and neck portion above the inward flange. The other chamber and the inside of the large tube container are communicated through a small through hole bored in the chamber and a gap between the leg tube 9 and the inner periphery of the inward flange 5.

The mouth and neck part 11 of a small tube container 10 made of synthetic resin is fitted onto the outer surface of the leg tube 9, and the small tube container is suspended vertically into the large tube container.

Reference numeral 12 denotes a cap, which screws the peripheral wall 13 hanging down from the outer periphery of the top wall 14 to the outer surface of the mouth and neck, and closes the upper surface of the reservoir chambers 8, 8 mentioned above with the lower surface of the top wall. They are provided with discharge ports 15, 15, respectively. Further, lid plates 16, 16 are attached to the outer edges of both the left and right sides of the top wall 14 via hinges 17, 17, and these lid plates cover the upper surfaces of both the left and right halves of the top wall 14 and close the discharge port 15. , 15 are tightly fitted by plugs 18, 18 attached to the lower surface. In order to facilitate the opening of the lid plate, recesses 19, 19 are bored on the outer surface of the upper end of both the front and rear parts of the peripheral wall 13.

"Effect of the invention" The present invention has the above-described structure, and the outer peripheral part of the bottom wall is placed inside the first neck part 4 of the large tube container body 1 and on the inward flange 5 on the inner surface of the mouth neck part. to fit the bottomed large diameter cylindrical portion 7 of the discharge passage forming member 6 in a watertight manner,
In addition, a small through hole is formed in the bottom wall of one of the left and right reservoir chambers 8, 8 provided by partitioning the inside of the cylinder, with a gap between the lower surface of the bottom wall of the large diameter cylinder and the inner periphery of the inward flange 5. A leg tube 9 that hangs down and is fitted into the second neck part 11 of a small tube container housed within the large tube container body, and a small through hole bored in the bottom wall of the reservoir chamber on the other hand,
Spout holes 15, 15 are formed in the upper portions of the left and right reservoirs of the cap top wall 14, which communicate with the inside of the large tube container through the above-mentioned gap, and which are fitted onto the outer surface of the first mouth and neck. These lid plates 16, 16 each have plugs 18, 18 that fit tightly into the spout holes.
onto the top wall 14 and the hinges 17, 17 to the outer edges of both left and right sides.
Open the lid plate and squeeze the body of the large tube container body to open the spout hole 15,
The creamy substance poured out from the storage chamber 18,
Therefore, even if the body attempts to restore its elasticity by squeezing and releasing the body after pouring, the cream filling inside the reservoir will be sucked back due to its elastic recovery. Outside air will not be sucked in unless the small through hole and the spout hole 15 communicate with each other. Therefore, the cover plates 16, 16 are closed until the small through hole and the spout hole 15 communicate with each other, and the stopper 1 is closed.
By sealing the spout holes 15 and 15 with 8 and 18, it is possible to reliably prevent outside air from being drawn into the body of each spout container.
It also prevents creamy products from deteriorating due to oxidation.

As the viscosity of the cream increases, it becomes difficult to suck back the cream material in the reservoir by restoring the elasticity of the body. The operation up to fitting can be carried out with plenty of time. In the case of a cream-like material with low viscosity, the above-mentioned tight fitting may be performed without releasing the compression of the body.
