Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a trigger-type dispenser that dispenses different types of contents filled in each container by simultaneously sucking, pressurizing, and mixing them by trigger check.
[0002]
[Prior art]
Some types of cosmetics such as adhesives and hair dyeing liquids are mixed with different types of drugs immediately before use. Uniform mixing and efficiency are required when dispensing such contents. A gun-type dispenser that uses a pump, aerosol, or trigger to drive a piston to suck, pressurize, mix, and discharge the contents in the cylinder is used.
[0003]
By the way, the conventional gun-type dispenser has a problem that when the contents are poured out from the container, the drive of the piston may be displaced and the contents cannot be discharged evenly.
[0004]
In addition, this type of dispenser discharges the contents wastefully because the amount of the contents dispensed by the check per trigger is always constant and the amount of the dispenser cannot be adjusted. There are also problems that are not easy to use.
[0005]
[Problems to be solved by the invention]
An object of the present invention is to provide a novel trigger type capable of stably dispensing a mixture in which a desired mixing ratio is obtained by sucking and pressurizing the same amount of contents from each container and appropriately adjusting the amount of contents to be dispensed There is a place to propose an dispenser.
[0006]
[Means for Solving the Problems]
The present invention is a dispenser that performs suction, pressurization, mixing and dispensing from each container filled with different types of contents by reciprocating the piston in the cylinder with a trigger check,
Comprising at least two cylinders for sucking and pressurizing the contents in the container, and pistons capable of reciprocating simultaneously in these cylinders,
Each cylinder is provided with a suction passage connected to the mouth of the container filled with the contents, and this suction passage is provided with a single discharge passage for discharging the contents pressurized in each cylinder toward the nozzle. Concatenated,
While contacting the rear end surface of the piston, it can move toward the nozzle and move away from the nozzle by rotating itself, thereby restricting the movement of the piston in the cylinder and reducing the amount of content dispensed. A pouring amount adjustment rod to be changed is provided ,
Each said container is a trigger type | mold dispenser characterized by consisting of a refill container and the outer cylinder which equipped this refill container and provided the convex part in the bottom part .
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described more specifically with reference to the drawings.
[0009]
1 to 3 show a trigger type dispenser according to the present invention as an example of a two-liquid mixing type, in which 1a and 1b are containers filled with different kinds of contents (thin and can be reduced in volume). Refill container etc.) 2 is an extractor body for mounting and holding containers 1a and 1b. The dispenser body 2 has a grip 2a and a swinging cover 2b that covers the containers 1a and 1b in a state where the containers 1a and 1b are mounted and held.
[0010]
Further, 3a and 3b are a pair of cylinders provided in the dispenser body 2, and the cylinders 3a and 3b are suction passages 4a and 4b connected to the respective mouth portions of the containers 1a and 1b and the suction passages 4a, It has a single discharge passage 5 that pressurizes and discharges the content introduced through 4b.
[0011]
Further, 6 is a three-point valve disposed in each of the suction passages 4a and 4b and the discharge passage 5, 7 is a nozzle connected to the discharge passage 5, and 8 is disposed inside the nozzle 7 to uniformly mix two kinds of contents. Screw type mixers 9a and 9b are pistons that slide in the cylinders 3a and 3b, and 10 is a pin that is supported by a pivot pin 2c provided on the dispenser main body 2 so as to be able to be checked. Trigger that engaged p with the pins 11a and 11b at the rear ends of the pistons 9a and 9b, and 12 contacts the rear end surfaces of the pistons 9a and 9b to adjust the amount of movement of the pistons 9a and 9b in the cylinder. This is a pouring amount adjusting rod that changes the pouring amount of the contents.
[0012]
When the grip 2a of the dispenser body 2 is gripped and the trigger 10 is repeatedly checked multiple times, the pistons 9a and 9b reciprocate simultaneously in the cylinders 3a and 3b, respectively, thereby the contents in the containers 1a and 1b. The material is sucked into the cylinders 3a and 3b through the suction passages 4a and 4b, and the sucked contents are pressurized in the cylinders 3a and 3b and continuously from the tip of the nozzle 7 through the discharge passage 5 and the mixer 8. Will be poured out.
[0013]
In the dispenser configured as described above, when the dispensing amount adjusting rod 12 is rotated and moved toward the nozzle 7, the pistons 9 a and 9 b are pressed toward the nozzle 7 in the cylinders 3 a and 3 b to trigger 10. The amount of movement of the pistons 9a and 9b during the check-up becomes small (the dispensing amount is small).
[0014]
On the other hand, when the dispensing amount adjusting rod 12 is rotated in the reverse direction, the pistons 9a and 9b move in the direction away from the nozzle 5 in the cylinder 2, thereby moving the pistons 9a and 9b when the trigger 10 is checked. Becomes larger (large amount dispensed).
[0015]
In the upper掲図1-3, the container 1a, there is shown an example in which to apply the refill container 1a _1, 1b ₁ and the 1b, the container 1 a as shown in FIG. 4 to 6, 1b has an inner layer outer layer It is also possible to use a delamination container that peels and reduces the volume from the inner wall surface.
[0016]
In the present invention, as an example, a two-liquid mixing type dispenser equipped with two containers filled with contents is shown as an embodiment, but by adding the number of cylinders and pistons, a plurality of kinds of contents can be added. Mixing and pouring are also possible and not limited to the case of mixing two liquids. Further, the containers may be arranged horizontally in parallel, or may be arranged vertically in parallel, and there is no limitation on this point.
[0017]
In particular, in those provided with the refill containers 1a ₁ and 1b ₁ as shown in FIGS. 1 to 3 above, the outer cylinders 1a ₂ and 1b ₂ that house the containers 1a ₁ and 1b ₁ are necessary. A convex portion t is provided at the bottom of the outer cylinders 1a ₂ and 1b ₂ , the refill containers 1a ₁ and 1b ₁ are removed from the suction passages 4a and 4b, and the outer cylinders 1a ₂ and 1b ₂ are filled with water or the like. By setting the outer cylinders 1a ₂ and 1b ₂ in the reverse direction and checking the trigger, the passage through which the contents pass and the inside of the nozzle can be easily cleaned.
[0018]
Further, when only the mixer 8 is washed, it is desirable that the nozzle 5 is removed and the mixer 8 is pushed out toward the front or rear end of the nozzle 5 so that it can be easily disassembled. In the case where the dispenser is stored with the nozzle removed, the nozzle replacement cap 13 with the packing P as shown in FIG. 7 can be attached, thereby drying the contents, Solidification can be easily prevented.
[0019]
【The invention's effect】
According to the present invention, a plurality of pistons can be driven simultaneously when the trigger is checked, so that the contents can be evenly discharged from the container, and a mixture having a predetermined mixing ratio can be stably poured out.
[0020]
Further, according to the present invention, since the piston dynamic drive mechanism can be shared regardless of the number, the number of parts can be reduced and the dispenser can be made compact.
[0021]
Furthermore, according to the present invention, since the amount of pouring can be adjusted only by adjusting the screwing amount of the rod, the contents can be used without waste, and the usability is greatly improved.
