Description

[Detailed Description of the Invention] Industrial Field of Use The present invention relates to a tool for discharging instant adhesive from a nozzle of the container by attaching a container containing instant adhesive.Cyanoacrylate As containers for instant adhesives, cylindrical or conical containers having a nozzle have conventionally been used.

During the bonding process, a hole is first made by cutting or pricking the tip of the nozzle with a pin, then the body of the container is grasped by hand and the contents are discharged onto the area to be bonded while controlling finger pressure.

In some cases, a method is also adopted in which a hose is led from an adhesive tank and a small pump is used to discharge the adhesive.

Problems that the invention aims to solve: However, even when containers made of soft polyethylene are used, it is painful to grasp the body of the container all day long and press the body of the container with force with your fingertips. It was hot. Particularly when the viscosity of the instant adhesive is high or when the instant adhesive is housed in a hard polyethylene container from the viewpoint of stability over time, fingertips experience significant fatigue.

On the other hand, dispensing work using the small pump described above can be said to cause less fatigue on the fingertips, but since the adhesive is guided from the adhesive tank to the hand using a hose, this hose becomes a hindrance and makes it difficult to perform the work. There were also some problems.

The present invention has been made for the purpose of providing an instant adhesive dispenser that solves these conventional problems.

Means for solving the problem The instant adhesive dispenser of the present invention is
A tool for discharging the instant adhesive from a nozzle N of the container P by attaching a container P containing instant adhesive, the tool having at least a portion of the upper periphery of the cylindrical propellant filling chamber 1 extended. and the container holding part 2,
A propellant outlet 3 having a sharp tip for piercing the container P is provided on the upper surface of the propellant filling chamber 1 and projects upward, and the propellant outlet 3 is provided inside the propellant filling chamber 1.
A valve 4 for opening and closing is normally biased to close the propellant outlet 1, and a lever 5 for advancing and retracting the valve 4 is provided outside the propellant filling chamber 1 so as to reach the side of the container P. The propellant filling chamber 1 is further provided with a propellant inlet 6 on the bottom or side surface of the propellant filling chamber 1 for filling the propellant filling chamber 1 with the propellant.

As the instant adhesive, 2-cyanoacrylate adhesives of various viscosities are used. The container P has a cylindrical or conical shape, and is often made of soft or hard polyethylene. A nozzle N is attached to the mouth of the container P, and during the bonding work, the tip of the nozzle N is opened by cutting or pricking with a pin.

The propellant filling chamber 1 consists of a cylindrical pressure-resistant container, and is filled with a propellant. As the propellant, a fluorinated hydrocarbon known by the trade name Freon, lower saturated hydrocarbons such as propane and butane, nitrogen, dimethyl ether, etc. are used.

In the dispenser of the present invention, at least a portion of the upper periphery of the propellant filling chamber 1 extends upward to form a container holding portion 2, into which the bottom side of the container P is fitted. The container holding part 2 is connected to the propellant filling chamber 1
It may be formed integrally with the same member as the member constituting the outer wall of, or may be formed with a separate member.

A propellant outlet 3 having a sharp tip for piercing the bottom of the container P is provided on the upper surface of the propellant filling chamber 1 to project upward. This propellant outlet 3 can be provided at the center of the upper surface of the propellant filling chamber 1, but in order to avoid the tip of the propellant outlet 3 from hitting the weld line formed at the bottom of the container P when molding, the propellant outlet 3 is placed at the center. It is desirable to provide them with a slight offset.

A valve 4 for opening and closing the propellant outlet 3 is provided inside the propellant filling chamber 1 and is normally biased to close the propellant outlet 1.

A lever 5 for advancing and retracting the valve 4 is provided outside the propellant filling chamber 1 so as to reach the side of the container P. By operating the lever 5 and retracting the valve 4 against the urging force, the propellant outlet 3 and the valve 4 are closed.
A gap is created between the propellant filling chamber 1 and the propellant in the propellant filling chamber 1 to be sent into the container P from the propellant outlet 3.

An injection inlet 6 is provided on the bottom or side surface of the propellant filling chamber 1, and the propellant is filled from there. The propellant for replenishment after the propellant is consumed is also filled from here. This propellant inlet 6 has a check valve.

The proximal end of the valve 4 is fixed to a long hole 11 provided at the rear end of the valve 4 with a pin 12 . Reference numeral 13 denotes stands provided at the lower periphery of the propellant filling chamber 1, and one of the stands 13 serves as a fulcrum for the lever 5.

A propellant inlet 6 is provided at the bottom of the propellant filling chamber 1 in this embodiment. The propellant inlet 6 has a check valve structure, and is configured to only allow the injection of propellant under pressure.

P indicated by a phantom line in FIG. 1 is a conical hard polyethylene container, and a 2-cyanoacrylate instant adhesive is housed inside. N is a nozzle provided at the upper end of this container P.

Function Next, the function of the present invention will be explained in the case of the above embodiment.

A container of the propellant filling chamber 1 in which a propellant (for example, Freon gas (registered trademark)) is introduced into the propellant filling chamber 1 in advance from the propellant inlet 6 to an appropriate pressure (for example, 2 to 8 Kg/cm ² ) and filled. When the bottom of the container P is fitted into the clamping part 2, the container P is fixed with the sharp tip of the projecting propellant outlet 3 sticking into the bottom of the container P.

In this state, the propellant does not enter the container P because the valve 4 closes the propellant outlet 3 from the inside.

With the tip of nozzle N of container P cut off,
Grasp the body of the container P together with the lever 5, and while keeping the nozzle N facing downward, direct the nozzle N toward the area to be bonded, and lightly bring the lever 5 closer to the container P.
The base end of the lever 5 moves downward in the figure using the stand 13 at the lower right of the figure as a fulcrum, and the valve 4 accordingly moves downward against the biasing force of the spring 10. As a result, the valve 4 injects The blockage state is released by moving a little away from the hole 3a of the agent outlet 3, and the propellant in the propellant filling chamber 1 enters the container P from the propellant outlet 3, and the internal pressure at that time causes instant bonding in the container P. Discharge the agent smoothly.

By appropriately adjusting the moving distance of the lever 5 toward the container P, the retracting distance of the valve 4, that is, the amount of instant adhesive discharged from the nozzle N can be controlled. Further, by finely adjusting the position of the pin 12 in the elongated hole 11 of the valve 4, the retraction distance of the valve 4 relative to the movement of the lever 5 can be adjusted.

Normally, by press-fitting the propellant into the propellant filling chamber 1 once, it is possible to discharge instant adhesive equivalent to several to ten containers P.

When the pressure of the propellant in the propellant filling chamber 1 drops, the propellant can be replenished by applying the spout of a separately prepared propellant filling cylinder to the propellant inlet 6 of the propellant filling chamber 1. . Incidentally, small propellant-filled cylinders are commercially available for purposes such as cooling agents, so they can be easily obtained.

Effects of the invention If the dispenser of the invention is used, the instant adhesive in the container P can be smoothly discharged from the nozzle N by simply pulling the lever 5 toward the container P, so whether the container P is soft or hard. Regardless of whether the viscosity of the instant adhesive in the container P is high or low, the dispensing operation can be performed smoothly.

Therefore, little force is required on the fingertips for dispensing, so even if the instant adhesive dispensing operation is performed for a long time, the degree of fatigue and pain of the worker is low.

Further, since a hose is not required unlike when discharging work is performed using a conventional small pump, the work is not obstructed by the hose.

If the shape of the dispenser is designed to have a stand 13 as shown in FIG. 1, it can be placed on a desk when use is interrupted.

The entire dispenser of this invention is simple,
It is compact and useful as a must-have tool for instant adhesive workers.
