In general, food utensils such as spoons, food spoons, forks, knives, ladles, etc. are manufactured by molding the shovel and handle part with the same material. There was a lack of expression of simple and various patterned handles.

In order to solve this problem, a reinforcing core is recently formed with one end of the insert of food utensils, and the coupling grooves formed with the insertion grooves and the handle seating portion and the reinforcing piece at the lower sides are coated with the adhesive of the bond material and then inserted into the inner insertion hole of the handle. Various decorative effects could be obtained by providing food utensils that were combined. However, since there are few adhesive parts, many defects are generated due to the separation after production, and the inserted joints are sterilized by applying moisture and heat due to washing. When the adhesive strength of the adhesive is weakened, there is a problem in which the handle is suddenly detached from the handle part and thus there is a problem in that it cannot be given a long term reliability.

In order to solve the above problems, the present inventors exclude adhesives such as bonds that are harmful to the human body, and in order to simplify the structure of the coupling handle portion, a gypsum in the handle portion coupled with the food utensil body is injected to form a natural friendly coupling structure. Proposed.

In other words, gypsum is harmless to human body and is widely used as a medical (dental) material recently, and the gypsum injected into the handle part is restored to its original state by re-evaporation even when water is absorbed after hardening. Since it retains its curing power, it has a feature that can give reliability of food products when used for a long time.

However, the following precautions should be taken to inject kneading plaster into products that take up a small volume, such as the handle of food utensils.

(1) Dough gypsum in the handle should be injected evenly, especially when it is injected into the space in the handle with a small volume such as a teaspoon.

(2) The kneaded gypsum is easily cured when it comes into contact with air, so when the curing retardant is added for mass production, the curing time may be delayed while the hardness of the gypsum is weakened.

(3) In the case of using a gypsum injector, an easy structure for cleaning the gypsum inside the injector is required.

The present invention is to solve the above problems,

It is an object of the present invention to provide a gypsum injection device in a handle of a food utensil capable of precisely injecting dough gypsum into the handle.

Another object is to provide a gypsum injection device in the handle of food utensils that can be mass-produced during the injection into the handle by allowing the kneaded gypsum to prevent hardening by contact of air to extend the working time.

Another object is to provide a gypsum injection device in the handle of the food utensil easy to clean in the gypsum injector used repeatedly.
