Description

[Detailed explanation of the idea] "Industrial application field" This case concerns two-color tubes.

"Conventional technology" Conventionally, an inner tube was loosely inserted into an outer tube,
As a two-color tube that can contain two different contents separately and extrude them together,
A fixed member is fitted to the mouths of both tubes, and a rotating member having a discharge port is attached to the fixed member, so that the discharge ratio of the contents from both tubes can be changed as the rotating member rotates. There is a device in which a discharge plug is formed as shown in FIG.

``Problem that the invention seeks to solve'' However, in actual use, it is often not necessary to adjust the discharge ratio of the two contents each time, and in such cases, it is unnecessary to have an adjustment means. This results in operational inconvenience, and there is the inconvenience that a stable predetermined ratio cannot always be obtained. In addition, the discharge port cannot be closed, causing the contents to leak, dry out,
It may cause deterioration etc.

The present invention is an attempt to solve these problems, and in addition, it is an attempt to make the switching operation and the overall opening/closing operation easier and faster.

"Means for solving the problem" In order to achieve the above object, the present invention loosely inserts the inner tube 2 into the outer tube 1, attaches the discharge plug 3 to the mouths 11 and 21 of these tubes, and The discharge plug has internal and external upright tubes 317, 3 concentric with the upper part of the fixing member 31 that fits into the mouths 11, 21 of both tubes.
18, and a rotating member 32 having a discharge port 321 at the center is rotatably fitted into the outer upright tube 317, and the inside of the inner upright tube 318 is connected to the inner tube 2, and the outside communicates with the outer tube 1, and constitutes a switching on-off valve 4 that switches the discharge of contents from both tubes to one, both, and the other as the two members rotate, and fully closes at the midpoint of each switching, The switching on-off valve has an inner cylinder 325 vertically opened from the inside of the rotating member 32 to the discharge port 321, and a stopper rod 326 arranged in the center of the inner cylinder.
The stopper rod is connected to the rim of the outlet 321 via an appropriate number of support pieces 327, 327, and the inner cylinder 325 and stopper rod 326 are rotated in and out of the inner upright cylinder 318. Fit freely, and insert each into the inner upright tube.

1 is provided.

The outer tube 1 and the inner tube 2 have the above-mentioned structure. Initially, the bottoms of the outer tube 1 and the inner tube 2 are left open, and different cream-like contents are filled from the bottom, and the bottoms are welded and sealed in a linear shape.

When pushing out the contents, the cap 7 is removed and the outer tube 1 is pressed, by appropriately rotating the rotating member 32 of the discharge plug 3. The switching valve 4 works, and the contents of both tubes 1 and 2 can be pushed out or stopped as desired.

The operation of the switching valve 4 will be explained with reference to FIG. 2 as follows.

When the rotating member 32 is at one end of rotation and the second notch 42 of the inner upright tube 318 and the longitudinal groove 44 of the stopper rod 326 match, the contents of the inner tube 2 are pushed out.

When the rotating member 32 is rotated 45 degrees from the state I, neither the notch nor the vertical grooves match, and the fully closed state is achieved.

When the rotating member 32 is further rotated by 45 degrees from the state shown in FIG.
The longitudinal groove 43 of 8 and the notch 45 of the inner tube 325 match, and the contents of both the outer tube 1 and the inner tube 2 are extruded together.

When the rotating member 32 is further rotated by 45 degrees from the above state, neither the cut nor the vertical groove will match, and the fully closed state will be achieved.

From the state of rotation member 32 to 45
When rotated once, the second notch 42 of the inner upright cylinder 318 and the notch 45 of the inner cylinder 325 match,
The contents of the outer tube 1 are forced out.

During these extrusions, the discharge valves 5 and 6 act to prevent outside air from flowing in.

"Effect of the invention" According to the present invention, a switching on-off valve 4 is configured which switches the discharge of contents from both tubes to one side, both sides, and the other side, and fully closes at the midpoint of each switching, and the switching on-off valve has the following features: Discharge port 321 from inside the rotating member 32
An inner cylinder 325 is vertically opened to the inner cylinder, and a plug rod 326 is disposed in the center of the inner cylinder, and the plug rod is connected to the discharge port 321 through an appropriate number of support pieces 327, 327.
The inner tube 325 and stopper rod 326 are rotatably fitted inside and outside of the inner upright tube 318, and are spaced apart from each other at an angle of 90 degrees from the inner upright tube. 1 and 2nd notches 41 that open upward;
42 and a third outer vertical groove 43, a vertical groove 44 that opens downward is provided at an appropriate position of the stopper rod 326, and a vertical groove 44 that opens downward is provided in the inner cylinder 325 at an angle of 180 degrees from the vertical groove 44. Since the notch 45 is provided, the discharge of the contents from both tubes can be switched extremely easily and quickly from one side to the other side by a slight rotation of the rotating member 32 every 90 degrees, and ,
When discharging both sides, the ratio can be maintained constant, a stable ratio can always be obtained, and there is no inconvenience of having to adjust it each time. Further, in the middle of each switching, that is, at an angle of 45 degrees, the outlet 321 can be completely closed, and therefore the outlet 321 can be closed by the rotating member 3.
It can be closed each time with a very slight rotation of 2, and the operation can be performed extremely easily and quickly.
By closing the opening, leakage, drying, deterioration, etc. of the contents can be accurately avoided.

Moreover, it is easy to manufacture, can be provided at low cost, and is extremely useful in practice.
