DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembling type measuring spoon for measuring the contents such as detergent contained in a container.

[0002]

2. Description of the Related Art Conventionally, a measuring spoon for measuring an object such as detergent contained in a container is generally a plastic molded product made of polypropylene or the like as a measuring spoon a shown in FIG. Met.

[0003] In recent years, environmental problems such as packaging containers have been highlighted, and the development of paper measuring spoons has been promoted in the trend of minimizing plastic molded products. As a paper measuring spoon, FIG.
As a measuring spoon b shown in (1), a pulp mold is known.

[0004] When the measuring spoon is made of paper, there is a problem that the cost is increased if the measuring spoon is manufactured by a pulp mold. Therefore, in consideration of economical and environmental problems, the measuring spoon is assembled by bending an original plate of cardboard or the like. An inexpensive assembly type is most desirable. However, in the measuring spoon, the strength of the grip portion (handle portion) is particularly important for usability. If the measuring spoon is formed of general cardboard, there is a problem that it is difficult to maintain the shape of the grip portion after assembly.

If the original plate is made of processed paper such as vulcanized fiber in the assembling type measuring spoon, the strength of the measuring portion and the gripping portion can be sufficiently ensured, and at the same time, the entire measuring spoon is incinerated lower than conventional plastic products. It is possible to discard with calories burned. However, this type of processed paper is expensive and difficult to obtain easily at present, and it has been difficult to actually use it.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems. In an assembling type measuring spoon, the whole spoon can be made of a general cardboard or the like and discarded. It is an object of the present invention to provide a low-cost assembled measuring spoon in which the configuration of the part is securely held.

As a result, the original plate 2 is divided into the measuring plate 12 and the side plates 14a and 14b. Further, between the pair of side plates 14a and 14b,
A bent portion 18 is formed by a combination of a slit and a ruled line.

As shown in FIG. 1, at the outer end of one side plate 14a, there is provided a folded piece 20 which is folded back to the back side of the other side plate 14b after the two side plates 14a, 14b are overlapped. In this assembling type measuring spoon E, the protruding piece 22 provided on the outer end of the other side plate 14b is turned into the hole 24 formed in the one side plate 14a by turning the turned piece 20 toward the other side plate 14b. The fitting portion 10
Is formed.

The folded piece 20 has a substantially equilateral trapezoidal shape.
It is folded back at a bent portion 26 composed of ruled lines and the like. Hole 24
Is formed by a cutout 28 that opens in a substantially U-shape toward the outer end of the folded piece 20. That is, this cut 28
The opening 24 is opened while the substantially U-shaped tongue piece 30 is erected by the pressing force received from the protruding piece 22 at the time of turning back.

In this embodiment, a pair of side plates 14a,

C is set so as to satisfy the relational expression C ≧ A> B. Further, the dimension D up to the lower edge of the hole 24 (the lower end of the cut 28) is set smaller than the dimension B up to the bent portion 26 of the folded piece 20.

That is, since C ≧ A, the pair of side plates 14
The upper edge of the projecting piece 22 when a and 14b are overlapped has a height equal to or lower than the upper edge of the hole 24. Also, when A> B, when the pair of side plates 14a and 14b are overlapped and the folded piece 20 is folded, the bent portion 26 of the folded piece 20 bends at a position lower than the upper edge of the protruding piece 22. Also, by B> D,
The bent portion 26 and the cut 28 of the hole 24 intersect.

Each of the bent portions 4a, 4b, 6a, 6b,
18, 26, folded piece 20, protruding piece 22, notch 28, etc.
For example, it is manufactured in a lump by punching and molding a flat paper base plate with a punching die.

Next, a method of assembling the assembly type measuring spoon E thus configured will be described. (1) First, the surfaces of the left and right side plates 14a and 14b are overlapped with each other from the state of the flat original plate 2 shown in FIG. At this time, since the left and right bent portions 4a and 4b bend, as shown in FIG. 3, the bottom wall 12a and the left and right side walls 12b and 12b are formed.
The measuring section 8 is formed by c. The cross section of the gripper 10 in this state is as shown in FIG. 4, and the various dimensions A, B, C, and D described above are expressed by the relational expression C ≧ A>B> D.
Meet.

(2) Next, as shown in FIG. 5, the folded piece 20 is folded back to the back side of the other side plate 14b via the bent portion 26. At this time, the upper edge of the projecting piece 22 is lower than the upper edge of the hole 24, and the bent portion 26 of the folded piece 20 is located at a position lower than the upper edge of the projecting piece 22. 14
When the folded piece 20a is folded toward the other side plate 14b, the projecting piece 22 automatically escapes to the hole 24. In other words, in this case, when the folded piece 20 is folded, the substantially U-shaped tongue piece 3 is formed.
0 is pushed by the upper edge of the projecting piece 22 and stands up, and the projecting piece 22 is allowed to escape into the hole 24 while opening the hole 24. When the folded piece 20 is further folded, as shown in FIGS. 6 and 7, the protruding piece 22 is further fitted into the hole 24, and at the same time, the tongue piece 30 rides over the protruding piece 22 and the back surface of the protruding piece 22. Side, and is firmly locked in a state where the back surface of the protruding piece 22 is pressed by the surface. Thereby, the pair of side plates 14
Thus, a grip portion 10 in which the a and b are integrated is formed.

According to the first embodiment assembled as described above, the following operation and effect can be obtained. That is, after the pair of side plates 14a and 14b are overlapped, the folded piece 20 of one side plate 14a is folded, and the protruding piece 22 of the other side plate 14b is fitted into the hole 24 on the folded piece 20 side. The paired side plates 14a and 14b can be securely held. Thus, even if the measuring spoon is formed of a paper base plate such as a general cardboard, the shape of the gripper 10 after the assembly can be surely held. Therefore, according to the present embodiment, in the assembling type measuring spoon, the spoon can be made of paper and can be discarded, the cost can be reduced, and the shape of the grip portion 10 after assembling can be surely held.

Also, since the protruding piece 22 can be easily fitted into the hole 24 during the operation of folding the folded piece 20,
After the pair of side plates 14a and 14b are overlaid, the grip 10 can be formed with one touch. On the other hand, if the dimension C is set smaller than the dimension A, the projecting piece 22 is formed in the hole 24 separately from the operation of bending the folded piece 20.
Therefore, the gripper 10 cannot be assembled with one touch. On the other hand, if the dimension B is set to be larger than the dimension A, the folded piece 20
2 is bent at a position higher than 2, so that the projection 22
Can not fit into

Further, according to the present embodiment, the pair of side plates 14a and 14b can be more securely held by the locking of the tongue piece 30, and the protruding piece 2 is formed by the spring force of the tongue piece 30.
2 is pressed against the one side plate 14a, so that the pair of side plates 14a and 14b can be closely contacted with almost no gap, so that the shape of the grip portion 10 can be made more preferable. Further, since the tongue piece 30 gets over the protruding piece 22, a certain click feeling can be obtained.

Also, since B> D, the substantially U-shaped cut 28 intersects with the bent portion 26, the bent portion 26 can be formed short by dividing the front and rear with the hole 24 (cut 28) interposed therebetween. At the same time, it is possible to secure a tongue piece 30 large enough to be locked by the protruding piece 22. Thereby, the grip 10
The spring force of the bent portion 26 after the formation can be reduced as much as possible, and the tongue piece 30 and the protruding piece 22 can be reliably contacted.

Next, an assembly type measuring spoon of a second embodiment will be described. As shown in FIG. 8, in the assembly type measuring spoon of the second embodiment, the hole 24 according to the first embodiment is previously opened without a tongue piece, in contrast to the configuration of the first embodiment. The configuration is constituted by the holes 32, and other configurations are substantially the same as those of the first embodiment.

In the assembling method according to the second embodiment, as shown in FIGS.
After a and 14b are bent at the bent portion 18 and each is erected and overlapped, the folded piece 20 is folded at the bent portion 26 as in the first embodiment, and the protruding piece 22 is inserted into the hole 32. Insert as it is. In this case, since there is no tongue piece 30,
An edge 32 a of the hole 32 is locked on the back surface of the projecting piece 22.

According to the second embodiment, since the hole 32 is formed in advance, the specific effect that the punching structure of the original plate 2 is simplified can be obtained.

The first and second embodiments are preferred embodiments of the present invention, and the technical scope of the present invention is not limited to this embodiment. For example, the number and shape of the projections / holes according to the present invention are not limited to the configurations of the first and second embodiments, but may depend on the thickness of the paper, the required strength of the gripper, the shape of the spoon, and the like. Can be set appropriately. Further, a measurement scale line may be provided in a portion serving as a measurement portion, and a structure may be employed in which the detergent or the like can be reliably measured.
