[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple food and drink tool made of synthetic resin, which is provided with functional parts such as a mudra, a spoon or a fork at its end and can be folded in the middle of a handle.

[0002]

2. Description of the Related Art It is well known that madras, spoons, forks, etc. used for eating and drinking are formed so as to be foldable and reduced in size when not in use to improve the convenience of storage and carrying. Known is Kokoku Sho 61-3426.

However, in the above invention, when the main handle and the auxiliary handle which are foldable at the thin-walled connecting portion are extended, the pins and grooves provided near these connecting portions are fitted in a direction in which they can be easily pulled out and the state is maintained. For this reason, the pin and groove are easily disengaged during use, and the ribs are provided on the surface to fit and hold the folded auxiliary handle. Then, there is a problem that a feeling of strangeness occurs during use, and that the structure is complicated and the undercut process is difficult.

[0004]

The present invention has been made by paying attention to the above points, and the problem is that it is not easily bent or disengaged during extension and folding, and is always easy to handle. In addition, the structure is such that there is no molding problem such as undercutting, and reliable extension and folding is possible.

[0005]

In order to solve the above-mentioned problems, the present invention relates to a foldable food and drink, in which the base portion 3 of the handle is integrated with a thin hinge 4 in a vertical position of the handle front portion 5. Molding was performed to form a first window 7 that vertically penetrates the base 3 adjacent to the end 6 provided with the hinge 4 of the base 3 of the handle, and the base 3 and the tip 5 of the handle are extended. The overlapping piece 8 that sometimes closes the first window 7 is attached to the hinge 4 of the tip 5 of the handle.
It is formed so as to project downward in the vertical direction from the end portion 9 provided with, and when the first window 7 is closed by the overlapping piece 8, the overlapping piece 8 engages to form the base 3 and the tip 5 of the handle. An engaging means 10 for holding the stretched state is formed between the first window 7 and the overlapping piece 8, and a locking portion 11 projecting vertically upward and laterally from the base 3 of the handle is laterally projected. When the handle 2 is bent together with the hinge 4 and the tip 5 and the base 3 are overlapped with each other, the locking portion 11 is inserted,
The second window 13 which can be locked is formed in the tip portion 5 of the handle so as to penetrate in the left-right direction.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A description will be given below with reference to the drawings. The embodiment is a case where the present invention is applied to a mudra, and a small spoon-shaped functional portion 1 for stirring is provided at the tip of an elongated handle 2, and a thin hinge in the middle of the handle 2. Four
Is provided and is made foldable, and is entirely made of synthetic resin (FIG. 1).

The handle 2 is divided into a base portion 3 and a tip portion 5 having the functional portion 1 at its tip, with a hinge portion 4 as a boundary, and adjacent to an end portion 6 of the base portion 3 on which the hinge 4 is provided, A first window 7 is formed that vertically penetrates the base 3, and the polymerized piece 8 closes the first window 7 when the tip 5 is extended with respect to the base 3.
Is formed so as to project in the longitudinal direction from the end portion 9 of the tip portion 5 provided with the hinge 4 (FIG. 2).

The hinge end 6 of the base 3 is about one half of the wall thickness of the handle 2, and the overlapped piece 8 following the hinge end 9 of the tip 5 underneath it has a similar thickness. The handle's tip 5 and base 3
Defining surfaces 6a, 8a that contact each other when the and are extended and keep the extended state are formed on the opposing surfaces of the hinge end portion 6 and the overlapping piece 8 (see FIGS. 4 and 5).

The first portion provided on the base portion 3 for holding the handle 2 in a straight shape when the base portion 3 and the tip portion 5 of the handle are extended.
The protrusion 10b is provided so as to protrude from the mouth wall of the window 7 of
The protrusion 10 near the tip of the overlapping piece 8 that closes the window 7 of the
A protrusion 10a engageable with b is provided so as to protrude (FIGS. 2 and 4). The protrusions 10a and 10b at these two locations are handles 2
The engaging means 10 for keeping the extension state is constructed.

Further, the base portion 3 of the handle 2 is formed with a locking portion 11 which projects vertically upward and sideways, and the base portion 3 provided with the locking portion 11 has a side protruding portion 11a. The die-cutting openings 12 for molding are arranged in parallel (FIG. 2). The locking portion 11 is inserted into and locked by a second window 13 formed in the front portion 5 that is folded and overlapped with the base portion 3 of the handle (FIG. 3, FIG. 5, chain line).

The food and drink having such a structure is molded in a state shown in FIG. 2, that is, when the base portion 3 of the handle 2 is horizontal, the tip portion 5 stands vertically with a thin hinge 4 therebetween. To be done. By doing so, the mold for injection-molding the food and drink of the present invention can be configured most rationally.

An example of the molding die is shown in FIG.
The upper surface sides of the base portion 3 and the tip portion 5 are the functional portion 1 of the food and drink tool of the present invention.
At the same time, a first mold 21 having a mold cavity formed on a mold surface forming a right angle, a second mold 22 forming a mold cavity for molding the lower surface side of the base 3 together with the first mold 21, and a second mold 22. Adjacent to the third mold 23 for molding the peripheral part of the polymerized piece 8 of the food and drink, and adjacent to the first and third molds 21 and 23, and the front part of the handle 2 and the functional part 1 And a fourth mold 24 for molding the lower surface side of the.

By configuring the mold in this way,
As a result of molding the food and drink of the present invention into a shape bent at 90 degrees with the hinge 4 as a boundary, the first window 7 and the locking portion 11 are
With the mold 21, the protrusion 10b at the lower part of the window and the mold removal port 12 including the engaging portion protruding portion 11a are molded by the second mold 22, respectively, and the concave shape of the madra is defined by the first mold 21. Since the second window 13 is molded by the first mold 24, there is no undercut portion.

In FIG. 6, reference numeral 25 is a pin-shaped slide core forming the die outlet 12, 26 is a protruding pin, and 27 is an angular pin used for sliding the fourth die 24 which is a slide core.

[0015]

Since the present invention is constructed and operates as described above, as shown in FIG. 2, the base portion 3 and the tip portion 5 are injection-molded very easily at a right angle, and the tip portion 5 is formed. It is halved in length by folding it onto the base 3 (FIG. 3) and when straightened it is in a straight line (FIG. 1). In the folded state, the locking portion 11 is inserted into and locked by the second window 13, so that the locking portion 11 does not easily come off. In the extended state, the defining surfaces 6a and 8a on both sides of the hinge overlap and the engaging means 10 engages. Since the handle 2 is kept in a straight line, there is no possibility of bending during use.

Therefore, according to the present invention, there is provided a folding and extending structure that eliminates molding difficulty, and the formed folding structure does not come off or bend except when it is operated intentionally. Play.
