DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a dispenser for accommodating viscous substances, particularly edible viscous substances such as mayonnaise and cream, and taking them out in fixed amounts.

<Prior art> Conventionally, in order to fill the voids generated in the interior and exterior of a building or the like, a cartridge containing contents such as caulking agent is attached to a trigger type dispenser, and the cartridge is pressed by the operation of the trigger, A dispenser for taking out a certain amount of a viscous material is described in Japanese Utility Model Publication No. 51-115718.

<Problems to be solved by the invention> Recently, when efficiently applying mayonnaise etc. to a large number of salads in restaurants, etc., the contents are stored in a dispenser having the above structure and used. It was However, in the conventional dispenser described above, the trigger and the piston for pressing the cartridge are directly connected to each other, which requires a large amount of force for the operation, and the amount dispensed in one operation is constant. Therefore, there was a problem that accurate quantitative pouring could not be performed. Also, because it is used for industrial purposes, parts other than the cartridge are made of metal and are heavy and difficult to handle due to problems such as durability, and part of the pressing part is exposed to the outside, so it can be used around water such as restaurants. When used, there was a problem that it easily rusted and was unsanitary.

An object of the present invention is to provide a novel viscous material dispenser that solves these problems.

<Means for Solving the Problems> The present invention was made to solve the above problems.
A cartridge containing part having a main body part and a cartridge containing part, and having a spout, a cartridge made of a flexible material and having an opening only on the front side is stored with only the front part fixed, and A manual edible viscous material dispenser that transmits the power of rocking to a piston and presses and extracts the contents in the cartridge by moving the piston. A trigger, a claw member connected to the trigger and having a claw at the end opposite to the connection side, a pinion gear driven via the claw member, and a first pinion coaxially connected to the pinion gear. A roller, a piston having a push-out plate at its tip end and provided to reciprocate in the cartridge storage portion, and the first roller and the piston are opposed to each other. And a second roller provided on the location, as well as pressing nipping said piston between said first roller and the second roller, and meshed with the pinion gear,
It has a stopper that prevents reverse rotation, the piston moves forward according to the amount of swing of the trigger, and the push plate at the tip of the piston pushes the bottom of the cartridge to deform the body of the cartrid to shorten. A dispenser for edible viscous material, characterized in that the contents can be discharged by a fixed amount at a time.

<Operation> The edible viscous material dispenser of the present invention is configured as described above, and when the trigger is operated, the claw member connected to the trigger transmits power to the pinion gear. As a result, the first roller, which is coaxially connected to the pinion gear, rotates, and the rotation of the first roller causes the piston that is press-contacted between the first roller and the second roller to move forward by an amount corresponding to the swing amount of the trigger. To do. Then, the push-out plate connected to the tip of the piston pushes the bottom of the cartridge, so that the body of the cartridge is deformed so as to be shortened, and the contents are poured out in a fixed amount.

<Example> An example of a dispenser for a viscous material according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a sectional view of a viscous material dispenser according to the present invention, in which 1 is a main body and 2 is a cartridge housing. The main body 1 and the cartridge housing 2 are made of resin, and particularly the cartridge housing 2 is made of a transparent resin so that the contents can be easily seen. The cartridge storage section 2 is detachably attached to the main body section 1. In the grip part 3 formed integrally with the main body part 1, a trigger 4 is incorporated so as to be swingable in a parallel direction,
A leaf spring 5 is continuously provided at the center of the rear portion of the trigger 4.
The end portion of the leaf spring 5 contacts the inner surface of the grip portion 3, and the restoring force of the leaf spring 5 causes the trigger 4 to always return to a fixed position.

On the other hand, above the rear portion of the trigger 4, a U-shaped claw member 7 having a pointed portion 6 at one end is continuously provided. A pinion gear 8 is provided at a position that meshes with the pointed portion 6 of the claw member 7, and the parallel motion of the trigger 4 is transmitted to the pinion gear 8 via the claw member 7 and converted into a rotary motion. The teeth of the pinion gear 8 are fin-shaped and have straight and curved portions. The pointed portion 6 of the claw member 7 is configured to surely mesh with the straight portion. A first roller 9 made of a soft material such as rubber is provided coaxially with the pinion gear 8. Although the number of pinion gears is one in this embodiment, a gear train in which several gears are combined may be used. In this case, the first roller 9 is connected to the terminal pinion gear.

The main body 1 is provided with a piston 10 and a push-out plate 11 at the tip thereof so as to be able to reciprocate in the cartridge housing portion 2. Further, the second roller 12 made of the same soft material as the first roller 9 has the above-mentioned first roller 9 and piston.
It is provided at a position facing the rod 13 of 10 and presses and holds the rod 13 by the first roller 9 and the second roller 12 (FIG. 2). The number of the second roller 12 may be one, but if two are provided as in the present embodiment, the rod 13 can be more stably held.

A cylindrical cartridge 14 made of a soft material such as a film material or aluminum filled with contents has a pouring nozzle 15 at the tip.
After mounting, the cartridge is inserted into the cartridge housing portion 2 and the spout nozzle 15 is aligned with the spout 16 of the cartridge housing portion 2.

Since the cartridge 14 is used in the present embodiment, it is extremely easy to replace the contents, and since the inside of the cartridge storage portion is not polluted, it is sanitary even when repeatedly used for filling food such as mayonnaise or ketchup. The advantage is that

A stopper 17 meshes with the pinion gear 8.
When the pinion gear 8 rotates in the forward direction (counterclockwise in FIG. 1), the stopper 17 abuts the curved portion of the pinion gear 8 and thus does not hinder the rotation, but the pinion gear 8 will rotate in the reverse direction. Then, the pinion gear 8 comes into contact with the linear portion of the pinion gear 8 to prevent rotation. An opening switch 18 is connected to the stopper 17, and when the opening switch 18 is pressed, the pinion gear 8 and the stopper 17 are disengaged from each other.

Next, the operation of the edible viscous material dispenser according to the present invention will be described.

When the grip 4 is grasped and the trigger 4 is pulled, the trigger 4 moves in a direction against the leaf spring 5, and the claw member 7 triggers the trigger 4.
Move at the same time. Then, the parallel motion of the trigger 4 is transmitted to the pinion gear 8 by the pointed portion 6 meshing with the pinion gear 8 and becomes a rotary motion. The rotation of the pinion gear 8 is the first roller 9 coaxially connected to the pinion gear 8.
Be transmitted to. The rod 13 of the piston 10 is the first roller 9
Since it is pressed and nipped by the second roller 12, the rotation of the first roller 9 is frictionally transmitted to the rod 13, and the piston 10 moves in the direction to push out the contents in the cylinder 2. Since the rod 13 moves by an amount commensurate with the amount of movement of the trigger 4, the piston 10 always moves by a fixed amount. Then, as the piston advances, the push-out plate 11 presses the bottom of the cartridge 14, so that the body of the cartridge deforms in the direction of shortening, and a certain amount of content is discharged from the pouring nozzle 15 screwed in front of the cartridge 11. It is poured out one by one.

When the trigger 4 is released, the leaf spring 5 tries to return the trigger 4 to its original position and applies a force in the opposite direction to the pinion gear 8, but the pinion gear 8 does not rotate in the opposite direction because the stopper 17 meshes with it. On the other hand, since the pointed portion 6 smoothly slides on the curved portion of the pinion gear 8, the claw member 7 and the trigger 4 return to their original positions.

When the piston 10 moves in the direction of the spout 16 of the cartridge storage unit 2 and all the contents have been poured out, the release switch 18
By pushing, the pinion gear 8 and the stopper 17 are disengaged and a reverse rotation is possible.
It suffices to pull the operating portion 19 provided at the end opposite to 11 to return the pinion gear 8 to the initial position.

FIG. 4 shows another embodiment of the viscous material dispenser according to the present invention. In this embodiment, a push button-shaped trigger 4 is attached to the grip portion 3, and a claw member 7 is provided on the trigger 4 and a leaf spring 5 is integrally provided on the claw member 7 at two positions, upper and lower. The stopper 17 has a leaf spring shape at one end, and an opening switch 18 is integrally provided there. By sliding the opening switch 18 in the lateral direction, the engagement between the pinion gear 8 and the stopper 17 can be released.

In this embodiment, since the trigger 4, the leaf spring 5, and the claw member 7 can be integrally formed, and the stopper 17 and the opening switch 18 can be integrally formed, the number of parts can be reduced, which is economical and easy to assemble. is there.

In any of the embodiments of the present invention, the pinion gear is the first
The rollers do not have to be directly connected but may be such that power is transmitted through several gear trains.

<Effect> According to the edible viscous material dispenser of the present invention,
Since the cartridge is configured to be deformed without being separated into the body and the bottom to push out the contents, there is no risk of foreign matter entering the cartridge and the inside of the cartridge storage section is not polluted, such as mayonnaise or ketchup. It has the effect of being hygienic even if it is repeatedly used for filling food. Further, when the trigger is operated once, the pinion gear rotates by one amount via the claw member, and the piston is advanced by the rotation of the roller coaxial with the pinion gear, so that it is possible to always discharge a fixed amount. It has an excellent effect that has not existed in the past. In addition, the amount of movement of the piston relative to the amount of movement of the trigger can be freely set by changing the diameter of the pinion gear and the first roller. Therefore, the amount of dispensing per trigger operation can be increased and the operating force of the trigger can be increased. It can be freely adjusted to be small.

Moreover, since large parts are not required, the parts are not exposed from the main body, durability can be greatly improved especially around water, and the number of parts is small, so assembly is easy.

In addition, since the whole can be made of resin and rubber, there are excellent effects such as weight reduction.
