Description

  The present invention relates to a twin tube extrusion apparatus in which two tube containers are crushed simultaneously and evenly, and the contents of the two tube containers are discharged at the same timing, and in particular, two types of materials are mixed at the time of use. The present invention relates to a double tube extrusion apparatus in which two tube containers filled with the contents of a two-component mixing type are crushed simultaneously and evenly, and the two agents are mixed and discharged in equal amounts.

Conventionally, a double-type discharge device that discharges so that two agents are mixed equally in use from two containers that are separately filled with contents of a two-component mixture type uses an aerosol container or a pump-type container. There was something that was there.
However, when an aerosol container or a pump-type container is used, the cost increases, and a simpler and cheaper device has been demanded.

  Conventionally, there are various devices for uniformly extruding the contents from the squeeze-type tube. For example, a drive container is obtained by sandwiching a tube container between two rollers and moving a lever-like drive piece with a finger. A roller-type tube squeezer (see Patent Document 1) that squeezes the contents of the tube container by driving two rollers by a driving roller gear that rotates together, and a pair of opening side end portions provided with a pair of rollers rotatably. When a tube container is sandwiched between them, a clamping force is exerted between the opening side end portions by the elastic force of the member, and when the roller is rotated with fingers, the tubular container is caught and the contents are uniformly pushed out. A diaphragm (see Patent Document 2) and the like are known.

If the cylindrical portion 31 is fitted, the tube container C can be easily attached to the apparatus main body A.
Further, if the pitches of the screws of the mouth portions of the two tube containers C are made different and the screws of the two joints J are also made to have different pitches accordingly, it is possible to prevent the contents of the two tube containers C from being mixed up. This is useful when using a two-component mixed tube container because it prevents the wrong contents from being mixed.

After the tube container C is attached to the container main body A, the gear shaft 43 of the two rollers R is fitted into the groove 13 while being guided by the guide 15 of the apparatus main body A. At this time, since the rack portion 14 is not formed in the groove 13 near the guide 15, the rotational operation portions 41 of the two rollers R that freely rotate can be engaged with each other, and the state is maintained. The inside of the groove 13 is raised.
When the guide shaft 15 is further lifted, the gear shaft 42 engages with the rack portion 14 of the groove 13.

When the rotation operation portion 41 of one roller R is rotated, the other roller R rotates in the opposite direction at the same angular velocity, and the rack portion 14 is provided on the side of the groove 13 adjacent to each other. The gear shaft 42 moves upward while meshing with the rack portion 14.
Eventually, the pressing roller portions 40 of the two rollers R come into contact with the tube container C, rotate and rise while pressing the tube container C, and push out the contents of the two tube containers C simultaneously and evenly.

The contents pushed out from the mouth portion of the tube container C are pushed through the communication hole 33 of the joint J and are pushed out from the opening 4 on each side to the communication path 7.
The extruded contents reach the neutral piece 8 erected in the vicinity of the center of the communication path 7 while filling the communication path 7, and the contents of the respective tube containers C are further sandwiched between the neutral pieces 8. The inside rises, merges at the upper end of the neutral piece 8, and is discharged from the discharge port 20 in a state of being mixed together.
In the present embodiment, since the neutral piece 8 that divides the communication path into two by a plane passing through the center of the discharge cylinder 21 is provided, the contents of the two tube containers C can be reliably discharged in equal amounts. When the mixing is performed as in the agent mixing type, mixing before use of the contents in which the reaction proceeds can be minimized.
When the two-component mixing type is not used, the contents are evenly pushed out by the two rollers R, so that there is no particular problem even if the neutral piece 8 is not provided.

Next, a description will be given of a second embodiment in which a speed reduction mechanism for facilitating the rotation operation of the roller is added.

Then, the other roller R meshing with this also rotates at the same time, the gear shaft 42 of each roller R meshes with the rack portion 14, and the two rollers R rise while crushing the tube container C.
At that time, the speed reduction mechanism G also rises together with the roller R while bringing the lower surface of the flat plate portion 55 into sliding contact with the upper surface of the slide table 16.
If the outer surface of the front and rear walls 2 is effective as a slidable contact surface, the slide table 16 is not necessarily required.

  The contents pushed out from the tube container C by the two rollers pass through the communication hole 33 of the joint J and are pushed out from the opening 4 on each side to the communication path 7 as in the first embodiment. The neutral piece 8 is reached while satisfying the above, and further rises in the discharge cylinder 21, merges at the upper end of the neutral piece 8, and is discharged from the discharge port 20 in a mixed state.
