Abstract

PROBLEM TO BE SOLVED: To enable a measuring spoon to be downsized as necessary and also improve operability and shape retention in molding by constituting a spoon of a container part and a handle and forming stretchable circular lateral bellows along a peripheral direction on a peripheral face of the container part. SOLUTION: Stretchable circular lateral bellows 6 are formed in a peripheral direction of a container part 1, wherein a peripheral face is divided into upper and lower parts across the bellows 6. An easy-to-deform and narrow circular bend 8 is formed between a cylindrical part 7 positioned above the bellows 6 and the bellows 6. In addition, an easy-to-deform and wide circular bend 10 is formed between a dish-like part 9 below the bellows 6 and the bellows 6. Thus the container part 1 can be deformed with simple operation, so that the part can be adjusted to a desired volume and also the spoon can be made compact, at times when it is not necessary. Therefore, a space in a carton required for storage can be made small, thereby allowing the carton to be downsized.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a measuring spoon used for measuring, for example, powder detergent and powdered milk.

[0002]

Generally, a commercially available powder detergent is accompanied by a measuring spoon as shown in FIG. This measuring spoon is formed by integrally molding resin, and is composed of an instrument portion (measuring portion) 30 having a measuring scale and a handle portion 31. By the way, such a measuring spoon is stored in a carton on the powder detergent when the product (powder detergent) is shipped. However, the space required for its storage was not small, so it was necessary to use a larger carton than necessary. This is not preferable in terms of not only high cost but also resource saving.

As a means for solving the above problems, the actual exploitation 5
In Japanese Patent Laid-Open No. 9-66116, a bellows structure (transversal bellows structure) is provided in which a bottomed cylindrical saucer portion is provided at the tip of a handle, and a side wall of the saucer portion is alternately and repeatedly formed with short sides and long sides. And a measuring spoon is disclosed. This measuring spoon
It has a shape as shown in FIG. 12, and has a saucer portion (container portion) 32 having a bellows structure, and a handle (handle portion) integrated with the saucer portion 32.
It consists of 31.

A measuring spoon of this type does not require a large space for storage if the portion of the bellows structure is retracted. Therefore, the size of the carton can be reduced. However, on the other hand, there is a problem that molding work is difficult. That is, the molded measuring spoon cannot be easily removed from the mold because the bellows structure portion becomes a resistance. Therefore, it is necessary to forcibly pull out from the mold by applying an excessive force, and the rate of occurrence of defects increases.

In addition, the measuring spoon of FIG. 12 has an internal volume that varies depending on the degree of opening of the bellows structure portion, so that it is difficult to measure a certain amount. That is, after confirming whether or not the bellows structure portion is completely opened, it is necessary to weigh it, which is troublesome. For example, if even a part of the bellows structure part is degenerated, the metering function cannot be exerted. Therefore, an object of the present invention is to provide a measuring spoon which can be made compact as necessary, is easy to mold, and has excellent shape retention.

[0006]

The above-mentioned object of the present invention is a measuring spoon comprising a container portion and a handle portion, the peripheral surface of said container portion being expandable and contractable in the circumferential direction. The solution is provided by a measuring spoon, characterized in that it comprises an annular weave. Further, the present invention provides a measuring spoon comprising a container portion and a handle portion, wherein the peripheral surface of the container portion is formed with a weft bellows portion formed by weft projections and depressions. .

In particular, it is preferable that the measuring spoon has an annular bent portion which is more easily deformed than other portions at the upper and lower positions of the weave and bellows portion on the peripheral surface of the instrument portion. That is, the measuring spoon of the present invention constitutes an annular weft bellows portion (weft bellows portion due to weft projections and depressions) that is expandable and contractable along the circumferential direction on the peripheral surface of the bowl portion, and therefore presses the bottom surface of the bowl portion. It can be transformed compactly. This is because the lower end of the weave and bellows contracts due to the force acting on the bottom of the vessel.
And, the whole weave and bellows part is bent upward with the upper end side as the center. In this way, when the part below the weft bellows is stored in the part above it, as a result, the instrument part is very compact, similar to a measuring spoon with a bellows structure that expands and contracts in the depth direction. Will be things. In addition, the deformation of the weave and bellows is performed by a click-like operation, so that
As in the case of 2, only part of the bellows does not open,
There is no problem that the internal volume is unknown.

At the same time, since the irregularities forming the weft bellows are provided along the depth direction of the vessel portion (that is, the weft bellows have a substantially gear-like shape), the weft bellows have resistance during die cutting. Don't Therefore, it can be smoothly removed from the mold, and the molding operation is easy. Moreover, since an unreasonable force is not applied to the molded product during the die cutting, the rate of occurrence of defects is low.

Further, the measuring spoon of the present invention is not easily deformed even when an external force perpendicular to the bottom surface of the instrument is applied, unlike the one having a transversal bellows structure which expands and contracts in the depth direction. This is because the weft bellows part is composed of unevenness along the depth direction of the vessel part as described above, and this unevenness causes deformation due to external force,
Because it resists to some extent. Therefore, the shape retaining property is excellent, the shape is prevented from being abruptly deformed during the weighing work, and the inconvenience of having to arrange the shape many times is eliminated.

In the measuring spoon, it is preferable that the peripheral surface of the container portion is tapered so that the sectional area of the container portion becomes smaller toward the bottom surface in order to make it easier to remove the mold. Further, it is preferable that the weft and bellows portions are formed in a plurality of stages in the depth direction of the vessel portion. This allows the measuring spoon to be even smaller when not in use.

Further, in order to obtain a sufficient strength even when molded from a thin sheet, it is preferable that the edges of the vessel portion and the handle portion are formed with barbs.

1 to 7 show a first embodiment of a measuring spoon according to the present invention. 1 is a perspective view of the measuring spoon in a state in which the instrument portion is extended to the maximum extent, FIG. 2 is a side view of the measuring spoon in the same state as FIG. 1, and FIG. 3 also shows a measuring spoon in the same state as FIG. A plan view, FIG. 4 is a partial cross-sectional view of the measuring spoon with the instrument part retracted by one step, and FIG. 5 is a plan view of the measuring spoon in the same state as FIG.
FIG. 6 is a partial cross-sectional view of the measuring spoon with the instrument part retracted in two stages, and FIG. 7 is a plan view of the measuring spoon in the same state as FIG.

In each of the drawings, 1 is a bowl portion, and 2 is a handle portion provided integrally with the bowl portion 1. The measuring spoon provided with the vessel portion 1 and the handle portion 2 is obtained by vacuum forming a polypropylene sheet having a thickness of about 0.3 to 0.8 mm. The handle portion 2 is provided with a pair of parallel ribs 3a and 3b for increasing the strength. Also, for the same reason, the vessel part 1
The edges of the handle 2 are bent to form the returns 4, 5.

Reference numeral 6 is an annular weft bellows portion (weft bellows portion due to weft unevenness or weft folds) that can expand and contract along the circumferential direction of the vessel portion 1. The peripheral surface of the vessel part 1 is divided into upper and lower parts with the weft bellows part 6 in between. Between the tubular portion (upper body) 7 located above the weft bellows portion 6 and the weft bellows portion 6, a narrow annular first bent portion 8 that is more easily deformed than the above is configured. are doing. In addition, between the dish-shaped portion (lower division body) 9 located below the weft bellows portion 6 and the weft bellows portion 6, a wide annular second bent portion 10 that is more easily deformed than those is provided. I am configuring. The deformability of the first and second bent portions 8 and 10 is due to the fact that the thickness of that portion is smaller than that of the other portions.

As can be seen from FIG. 2, the peripheral surface of the vessel portion 1 is tapered so that the diameter and hence the cross-sectional area becomes smaller toward the bottom side. This is to make die cutting easier. As shown in FIG. 1, the measuring spoon having the above-mentioned configuration can store about 25 g of the powder detergent when the container portion 1 is maximally extended. In other words, 25g of powder detergent
Only available for weighing.

When an upward force is applied to the bottom surface of the vessel portion 1 from this state, the first and second bent portions 8 and 10 are deformed, and the weft bellows portion 6 contracts on the lower end side (that is, the diameter decreases). ), As a whole, bends upward around the upper end. As a result, about half of the lower body 9 is hidden by the weft bellows 6. This state is as shown in FIGS. 4 and 5, and can store about 20 g of the powder detergent.
In other words, it can be used to weigh 20 g of powder detergent.

When an upward force is further applied to the bottom surface of the vessel portion 1 from the state shown in FIGS. 4 and 5, the first and second bent portions 8 and 10 are further deformed accordingly, and the weave and bellows portion 6 is formed. Bends until it forms a substantially right angle with the peripheral surface of the upper body 7. Along with this, the entire lower body 9 is hidden by the upper body 7. This state is as shown in FIGS. 6 and 7, which can be used to weigh about 15 g of powder detergent.

As described above, in the measuring spoon of this embodiment, the instrument part 1 can be deformed by a simple operation,
Its capacity can be adjusted as required. Also,
Since the container 1 can be deformed, the measuring spoon can be made compact except when necessary. Therefore, the space inside the carton required to store it may be small, and the carton can be miniaturized.

In the measuring spoon, since the weft bellows portion 6 is composed of the unevenness provided along the depth direction of the vessel portion 1, that is, the weft direction, the weft bellows portion 6 resists during die cutting. It can be removed from the mold smoothly. Therefore, the molding operation is easy, and it is not necessary to apply an unreasonable force to the molded product, so that defects are less likely to occur. Further, unlike the conventional structure (structure that expands and contracts in the depth direction of the vessel portion), it is not easily deformed even when an external force perpendicular to the bottom surface acts, and it has excellent shape retention. Therefore, as long as it is not artificially operated, it will not be abruptly deformed during the weighing work, and there is no inconvenience that the shape must be adjusted many times.

8 to 10 show a second embodiment of the present invention. FIG. 8 is a side view of the measuring spoon with the instrument part fully extended, FIG. 9 is a partial cross-sectional view of the measuring spoon with the instrument part retracted in two stages, and FIG. It is a partial cross-sectional view of the measuring spoon in a state of being degenerated in stages. The structure of the measuring spoon of the second embodiment is basically the same as that of the first embodiment described above, but differs from the measuring spoon of the first embodiment in that weft bellows are provided in two upper and lower stages.

8 to 10, 11 is a vessel portion, 12 is a handle portion, ribs 13a and 13b are provided on the handle portion 12, and barbs 14 and 15 are provided at the edges of both. There is. Reference numerals 16 and 17 denote a first weft bellows portion and a second weft bellows portion. The vessel portion 11 is composed of the first weft bellows portion 16 and the second weft bellows portion 17 so that the upper division body 18, the middle division body 19,
Divided into lower body 20.

A first bent portion 21 is provided between the upper half body 18 and the first weft bellows portion 16, and the first weft bellows portion 16 and the middle split body 1 are provided.
9, a second bent portion 22 is provided, a third bent portion 23 is provided between the intermediate body 19 and the second weft bellows portion 17, and a second weft bellows portion 17 and a lower part are provided. Fourth bent portions 24 are provided between the body 20 and the body 20, respectively. As shown in FIG. 8, the measuring spoon having the above configuration can store about 25 g of the powder detergent when the container portion 11 is maximally extended.

In this state, when an upward force is applied to the bottom surface of the vessel portion 11, the second weft bellows portion 17 and below are deformed as in the first embodiment. However, in the measuring spoon of the second embodiment, the operation which was performed in two stages in the first embodiment is continuously performed to transform the state into the state shown in FIG. 9 at once. In the state shown in FIG. 9, about 20 g of powder detergent can be stored in the container 11.

When an upward force is further applied to the bottom surface of the vessel portion 11 from the state shown in FIG. 9, the portions below the first weft bellows portion 16 are deformed as shown in FIG. In this state, about 15 g of powder detergent can be stored in the container 11. In the second embodiment, in addition to the above-described effects, the weave bellows wall is provided in two stages, so that the container portion can be made more compact than that in the first embodiment, and the carton can be miniaturized. Show more effect.
