Description

[0001]
[Technical field belonging to the invention]
The present invention can be assembled, held in a folded state before use, and can be easily stretched and assembled during use, ensuring strength from various directions against the stretched state. An eating utensil that can retain its form.
[0002]
[Prior art]
Attempts have been made to attach eating and drinking utensils to dessert foods and instant foods, but it is possible to fold by connecting the handle part and the scooping part with a hinge part in a synthetic resin spoon. In some cases, a food utensil or the like that can be assembled by providing a fitting portion at the scooping portion may be used.
[0003]
However, since the assembling method at the time of use is difficult or has a hinge portion, the material used for the eating utensils is flexible and there is a problem such as insufficient strength. In particular, the shape of the food utensils for folding is complicated, and molding with synthetic resin has a complicated mold, resulting in poor productivity, and it may be difficult to perform the folded state.
[0004]
[Problems to be solved by the invention]
Therefore, the present invention solves the problems as described above, and can be easily assembled in a folded state by simply fitting separate parts of the handle part and the scooping part molded with synthetic resin, The user intends to provide an edible utensil that can be used easily from a folded state by sliding and assembling the handle portion and the scooping portion.
[0005]
[Means to solve the problem]
In the present invention, the handle portion and the scooping portion of the edible utensil are formed of separate parts, and the scooping portion is provided with a continuous slide rail for fitting and sliding with the handle. The handle part is integrated with the scooping part as a edible utensil, and it is stretched by human hands from a small state when used, but the handle is used to hold the slide rail of the scooping part It has a slide guide.
[0006]
The assembly of the two parts of the handle and the scooping portion, which are configured separately, is completed only when the insertion edge of the scooping portion gets over the guide wall of the handle slide guide in the folded position. At the time of use, the scooping portion is slid from the handle to the shape of the edible utensils by extending the handle from the folded state, but the handle and the scooping portion are formed on the scoop to maintain the folded state. The scooping side stopper can be held in a folded state so as not to slide easily by the storage stopper provided on the handle.
[0007]
When assembling by moving the scooping part forward and sliding from the handle part, the scooping part side stopper formed on the scooping part is released from the folded state by overcoming the storage stopper provided on the handle part. In addition, in order to maintain the stretched state, the climbing edge provided on the partially cut-out slide guide on the handle side gets over the stopper inclined part provided on the fixed rib on the scooping side, and the fixed rib does not return. And with a partially cutout slide guide return prevention stopper, it has a function to prevent it from returning. Moreover, the state where the scooping side stopper provided in the scooping part interferes with the advance prevention column provided in the handle part and is extended is fixed, and the eating utensil is assembled in a usable form.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The present invention comprises a handle 2 molded from a synthetic resin in the same manner as the scooping portion 1 molded from a synthetic resin. FIG. 1 shows a form in which the scooping portion 1 and the handle 2 are extended to a state where they can be used as an eating tool. FIG. 2 shows a state in which the scooping portion 1 and the handle 2 are folded.
[0009]
The assembling of the scooping portion 1 and the handle 2 is performed in the folded position shown in FIG. In assembly, a guide wall 15 having a cross-sectional shape of a plurality of slide guides 10 provided in parallel with the handle 2 comes into contact with an insertion edge 9 integrated with a slide rail 7 provided continuously in parallel with the scooping portion 1. Positional relationship. By forcibly fitting from the contacted position, the guide wall 15 gets over the insertion edge 9 and the assembly can be completed as shown in FIG. A reinforcing rib 8 is provided on the slide rail 7 for the purpose of increasing the strength of the scooping portion 1.
[0010]
The scooping portion side stopper 3 shown in FIG. 4 is provided with a scooping portion side stopper 3, and the cross-sectional shape of the scooping portion side stopper 3 is shown in FIG. 6. When the scooping portion side stopper 3 is extended and assembled so that it can be used as a food tool, the scooping portion side stopper 3 gets over the storage stopper 14 provided on the handle 2 and enters an assembling operation. The storage stopper is for holding the folded state. Therefore, when the scooping portion side stopper 3 gets over the storage stopper 14, the storage stopper is provided with a slight resistance.
[0011]
The sliding of the scooping portion 1 and the handle 2 can be smoothly slid by the slide guide 10 provided in parallel with the handle 2 and the slide rail 7 provided continuously in parallel with the scooping portion 1.
[0012]
In order to fix the scooping part 1 and the handle 2 in a state in which the scooping part 1 and the handle 2 can be used as food utensils by the sliding structure, the fixing ribs 4 provided in two places in pairs on the scooping part 1 shown in FIG. The crossover edge 16 in the partially cutout slider guide 11 provided in two pairs with the handle 2 begins to interfere with each other and becomes resistance during assembly, but applies a force to move forward as it is As a result, the inclined portion 5 gets over the ride-over edge 16 and enters the fitted state as shown in FIG. 18 together with the fitting sound, and the force that causes the return-preventing stopper 17 and the return-preventing edge 18 to lock and return to the folded state. Can withstand strong.
[0013]
Moreover, by installing the slide guide large 12 in pairs, the contact area of the handle portion with the slide rail 7 can be increased, and the strength against the force applied during use as a food utensil is ensured. When assembled, the scooping portion side stopper 3 contacts the advancing prevention column 13 provided on the handle 2 and stops the force to be extended beyond that position at the scooping portion 1 by stopping the scooping portion 1. When the handle 2 is extended, it is fixed and can be used as a food tool.
[0014]
【The invention's effect】
As described above, the assembly type folding food utensil of the present invention is not flat and bulky in the folded state, and can be easily attached directly to the food container, and can be used by simply sliding the handle when assembled. Is possible. As described above, since the strength of the mating state is strong and can withstand forces from all directions, the joint is a strong eating tool. The food utensil according to the present invention is made of synthetic resin such as polystyrene and polypropylene, and is performed by an injection molding method. However, neither the handle part nor the scooping part has a complicated structure such as a split mold using a slide method as a mold structure. Productivity is high. Also, assembling can be done with a small force, so it is possible to assemble easily and automatically by using a robot that takes out the molded product by using the method of simultaneously molding the handle and scoop in the mold. Is possible. Therefore, assembling is also highly productive and can be supplied in a large quantity at a low price.
