2. Description of the Related Art Conventionally, as a putty tray to be used when a worker carries a desired amount of putty to a work place when applying a high-viscosity paste-like putty such as a sealing agent and a jointing agent with a spatula, etc. , The veneer plate that was scrapped at the work site was used as the upper plate,
A simple one is also used, in which scrap wood is used as a handle on the back surface and is nailed with a nail or the like.

In this case, since the plywood has a wood grain, when the putty is handled on the surface, the pate gets into the wood grain and a spatula is caught on the wood grain, making it difficult to handle and there is a problem in workability.

Further, since it is made of wood, it is not light in weight, and when the putty is put on, it becomes a considerable weight. In addition, when it is used for a long period of time, the water content of the putty is transferred to the plywood plate, and the cured putty adheres to the plywood to make it even heavier, and the workability gradually deteriorates.

Further, there is a problem in strength such that the moisture in the putty is transferred to the veneer plate and the veneer plate is deteriorated and becomes brittle. Further, although the putty tray is washed after the work is finished, there is also a problem of washability such that it is difficult to remove the putty because it is made of wood.

On the other hand, in order to solve the above problems, putty trays made of plastic are manufactured.

In this plastic putty tray, the putty is difficult to stick to the upper plate, the workability is good, and the washability is also good. Further, even when used for a long period of time, moisture of the putty and hardened putty do not adhere to the putty, and the putty does not become heavier than that.

[0008]

However, since the above-mentioned plastic putty tray requires an expensive manufacturing mold for manufacturing, the mold material cost and the manufacturing cost itself are high. The manufacturing cost rises significantly, and the manufacturing cost is not low. Also, the weight issue remains unsolved.

It is an object of the present invention to obtain a putty tray which is inexpensive to manufacture, has excellent water resistance and washability, and has a reduced weight.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a sectional view showing the construction of an embodiment of the putty tray of the present invention. As shown in the figure, a rectangular upper plate 1 on which a paste-like putty is placed and a substantially U-shaped handle 2 provided on the lower portion of the upper plate 1 are integrally formed by die molding.

The material is styrofoam, and 10 times foaming provides sufficient strength. The specific manufacturing procedure is as follows. First, styrofoam beads were injected into a mold in which the upper plate 1 and the handle 2 are integrated and set in a heating device. At this time, the expanded styrofoam beads are foamed 10 times to form a putty tray molded product (that is, 10% of the molded product is injected). Next, after foaming by heating at a heating temperature of 110 ° C., it was cooled and released from the mold.

Since the styrofoam mold is molded at a low melting point of the styrofoam, it has a simpler structure than an ordinary plastic mold, and is characterized in that the manufacturing cost of the mold is low. The manufacturing cost of the mold of the foamed resin molding used in the present invention is about 1/3 of the manufacturing cost of the mold for injection molding. In addition, since the manufacturing can be performed at a relatively low temperature (110 ° C.), it is easy and suitable for mass production.

In the molded article of putty tray which is integrally molded,
The foamed pores of Styrofoam are exposed on the surface of the upper plate 1, and if it is used as a putty tray in this state, the putty will enter the pores and stick to it, so that more force will be applied to the upper plate during work. And the putty tray is damaged.

Therefore, the resin film 3 is attached to the surface of the upper plate 1 of the molded article of the putty tray, the molded article is again mounted to the mold, and a means for heat-sealing the resin film by heating is taken. As a result, the resin film 3 is coated on the surface of the upper plate by heat fusion, so that the surface strength of the upper plate 1 can be improved, it is difficult to peel off during the work, and it can endure long-term use.

That is, the plastic deformation of the putty tray is made by the putty and the upper plate 1.
Since the resin film 3 makes it difficult for the putty to adhere , the strength is also sufficient .
It

Further, the handle 2 is formed in a direction along the longitudinal direction of the rectangular upper plate 1. Also by this, the strength required for working is sufficient. That is, when transferring a desired amount of putty from the putty tray with a spatula and applying it to joints such as walls,
It is always transferred from the longitudinal direction to the spatula. For this reason, since the mounting direction of the handle 2 and the longitudinal direction of the upper plate 1 are configured to be the same direction, the strength required during the work is sufficient.

The structure of the handle 2 is defined by the longitudinal direction of the upper plate 1.
If it is installed in the direction along the
There is no U-shaped internal hole other than the U-shaped one.
Something that is a dent, something that is simply a protruding plate, etc.
Can have various configurations. In addition, the size of the putty tray is various.
You can take your own.

As described above, since the putty tray according to the present invention has the above-mentioned structure, it has the following excellent effects. (A) Since it is made of foamed resin, it is possible to significantly reduce the weight as compared with the conventional wooden and plastic putty trays. (B) Since the surface of the upper plate is covered with a resin film, it is superior in water resistance, washability, etc. as compared to a wooden putty tray,
It can achieve the same performance as a plastic putty tray. (C) Compared with a plastic putty tray that requires an expensive manufacturing die, the manufacturing cost can be significantly reduced.
