Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solid soap used for washing objects to be washed, such as shoes and bags, and more particularly to a bar-shaped solid soap which facilitates local washing of the objects to be washed. .

[0002]

2. Description of the Related Art A bar-shaped solid soap that makes it easy to wash a local portion to be washed such as inside a shoe or bag is disclosed in
Japanese Patent Application Laid-Open Nos. 52950 / 64-7250 and the like.

[0003] The solid soaps described in these publications are formed in a size and length that are easy for a worker performing a washing operation to hold by hand and that can be easily inserted into the interior of shoes or bags. In general, an operator grips both sides of a bar-shaped bar having a rectangular or circular cross section with the thumb, middle finger and ring finger of the hand, and holds the bar with the index finger so that the bar does not rotate. A cleaning operation is performed by rubbing the tip of the soap against the above-mentioned site to be cleaned. However, the above-mentioned Japanese Utility Model Publication No. 60-52952
The conventional bar soaps described in Japanese Patent Publication No. 0 and Japanese Utility Model Publication No. 64-7250 have the following problems.

[0004]

[Problems to be solved by the invention] (1) Japanese Utility Model Application 60-5
The solid soap described in 29520 and Japanese Utility Model Application Laid-Open No. 64-7250 has a square or circular cross-section, so that the fingers that sandwich the solid soap from both sides are slippery,
It is difficult to work. In particular, as described in Japanese Utility Model Application Laid-Open No. 60-529520, the solid soap having a square cross section makes the corners interfere with the operator's hand, making it difficult to grasp, making the work more difficult. Further, in order to prevent slipping of the fingers of the hand, a wrapping paper which can be separated by a predetermined length is wrapped around a bar of solid soap. However, the formation of such auxiliary non-slip means increases the cost. Each time the soap is consumed, the wrapping paper must be broken to adjust the protrusion amount, which is troublesome.

(2) Among the solid soaps, those having a hexagonal cross section or irregular shapes in addition to a square or a circle are commercially available. FIG. 9 is a perspective view showing a conventional example of a solid soap having a hexagonal cross section.
Is similar to the above in that the gripping area is small and the finger HF of the operator is slippery and the work is difficult. Further, the solid soap used for cleaning objects to be washed such as shoes and bags is formed relatively hard so that the solid soap is not easily deformed by the gripping force and the body temperature of the operator when gripping. It is common. Therefore, if the cleaning operation is performed for a long time, the finger HF of the worker touching the corners 102 'and 104' of the solid soap 100 'becomes painful as shown in FIG. 9, and the operation becomes difficult.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and can perform a washing operation without slipping of a finger only by gripping a solid soap with a light force, and an auxiliary slip prevention of a wrapping paper or the like. It is an object of the present invention to provide a solid soap that does not require any members. In particular, another object of the present invention is to provide a soap bar that can achieve the above-mentioned object only by changing its shape.

[0007]

In order to solve the above-mentioned problems, a bar of the present invention comprises a grip surface formed on both sides of a bar along the longitudinal direction thereof, and the grip surfaces of the bar. Between the gripping surface and the pressing surface formed between the gripping surface and the pressing surface, and formed between the gripping surface and the pressing surface, during the cleaning operation, the hand of the operator and the rod-shaped body. And a retracting portion formed inward of the rod-shaped body with respect to the gripping surface so that the tip of the operator's finger that grips the rod-shaped body is placed on the inclined surface. It is characterized by the following.

[0008] Since the fingertip is placed on the retracted portion formed inward from the gripping surface and the solid soap is held on the two surfaces, the gripping surface and the holding surface, the finger is held during the cleaning operation. It is less slippery and can perform cleaning work stably. In addition, since the operator's finger does not touch the corner of the bar, the finger does not hurt even after working for a long time. Further, since a slope is formed between the gripping surface and the holding surface so as not to interfere with the operator's hand, the corner does not interfere with the work. It is preferable that the dimensions of the gripping surface and the pressing surface and the positional relationship between them are determined in consideration of the ease of the cleaning operation.

Specifically, the distance between the two gripping surfaces is 20 mm
The thickness is preferably in the range of 60 to 60 mm, and more preferably in the range of 30 to 50 mm. The distance between the grip surface and the pressing surface is equal to 0.
32 times to 0.48 times, preferably 0.35 times to
It is better to be within the range of 0.45 times. The width of the grip surface is preferably 5 mm or more, more preferably 8 mm or more, and even more preferably 10 mm or more. The width of the pressing surface is preferably 5 mm or more, and more preferably 10 mm or more. From the various bar soaps manufactured within such a size range, the one most suitable for the operator's own hand can be selected.

A slope 112 is formed between 0 and 0. This slope 112
As a result, a recess 118 is formed from the grip surfaces 102, 102 to inward into the bar 100. Thus, the solid soap 100 of this embodiment has an octagonal cross section.

One end of the solid soap 100 has a solid soap 1
The upper and lower surfaces and the left and right surfaces of 00 are cut off obliquely to form a pyramid-shaped cleaning unit 120. When performing cleaning work,
The cleaning is performed by pressing the top of the cleaning unit 120 against a site to be cleaned such as shoes or bags (not shown). Note that the washing unit 120 may be formed not only at the one end but also at the other end so that the washing operation can be started immediately without having to change when the solid soap 100 is gripped.

The grip surfaces 102, 102 and the holding surface 104,
The flat surface 110 is formed from the cleaning unit 120 to the other end along the longitudinal direction of the soap bar 100. Bar soap 100
The total length, hardness and components of can be variously changed according to the type and size of the object to be cleaned such as shoes and bags. In the present invention, the provision of the gripping surfaces 102, 102, the holding surface 104, and the retraction portion 118 enables the cleaning operation to be performed by firmly holding the solid soap 100 with relatively light force. High hardness is not required. Specifically, the hardness of the solid soap 100 is preferably in the range of 5 to 9N, and more preferably in the range of 6 to 8N.

The solid soap 100 may be formed of a known component, for example, a soap or a composite soap containing 40 to 90% of an alkali metal salt of a saturated or unsaturated fatty acid having 8 to 22 carbon atoms. Other components include anionic surfactants other than fatty acids, cationic surfactants, alkali agents such as silicates and carbonates, chelating agents such as zeolites and organic phosphonic acids, fragrances, pigments, and the like, usually soaps and complex soaps. Can be arbitrarily compounded. On the other hand, the width and height of the solid soap 100, the grip surface 102
The width dimension of the holding surface 104 (the vertical dimension of the gripping surface 102) is determined in consideration of variations in the size of the hands of the worker.

[0015] Specifically, the distance between the grip surfaces 102, 102, ie, the width L of the bar 100 in this embodiment.
TT is preferably in the range of 20 mm to 60 mm,
More preferably, it is in the range of 30 mm to 50 mm. In this embodiment, the distance between the gripping surfaces 102, 102 and the pressing surface 104 is represented by a vertical height difference HCP from the center position of the gripping surface 102 to the pressing surface 104. It is preferably 32 times to 0.48 times, and more preferably 0.35 times to 0.45 times.

The width LPT of the pressing surface 104 is preferably 5 mm or more in consideration of the thickness of a general human finger, and is preferably 10 mm or more. Width HPT of grip surfaces 102, 102
Is 5 mm in consideration of placing the tip of the finger
It is preferable that the thickness be 8 mm or more.
More preferably, it is 10 mm or more. Slope 106, 1
The inclination angle α of 06 is determined by the various dimensions described above, and is preferably in the range of about 5 ° to 60 °,
In order to secure a sufficiently large space 108 and at the same time to secure a sufficiently wide grip surface 102 and holding surface 104,
It is preferable to be in the range of 10 ° to 45 °.

The solid soap 100 described above can be modified into various forms within the scope of the present invention. For example, the shapes of the slopes 106, 106 hold a space 108 large enough not to interfere with the hands of the working person.
It is not necessary that the surface be a flat surface, as long as it can be ensured between the second surface 02 and the pressing surface 104. As shown in FIG. 4 (a), an arc surface 126 curved convexly toward the outside of the soap bar 100. Alternatively, as shown in FIG. 4B, an arc surface 128 may be formed to be concavely curved toward the inside of the solid soap 100.

Further, if the shape of the solid soap 100 is formed into an octagon that is symmetrical left and right and vertically symmetrical, the flat surface 110 can function as the holding surface 104, and there is no need to change the position by preventing vertical holding errors. Cleaning work can be performed quickly. When the flat surface 110 is used as a pressing surface, the retracted portion 118 formed by the slope 112 functions as a space for preventing interference with the operator's hand, and the space 108 formed by the slope 106 is used by the worker. It functions as a retractable part where you can place your fingertips. In addition, if the grip surfaces 102, 102 and the pressing surface 104 having a fixed width can be secured, the cross-sectional shape of the solid soap 100 does not necessarily have to be an octagonal shape.
It may be formed in a heptagon shape without 10.

Next, another embodiment of the fixed soap of the present invention will be described.
This will be described with reference to FIGS. The basic form and the dimensions of each part of the fixed soap in the embodiment of FIGS. 5 to 8 are the same as those of the solid soap 100 of the previous embodiment.
The same reference numerals are assigned to the same portions as those of the solid soap of FIG. 3 to omit detailed description.

In the embodiment shown in FIG.
A vertical groove 2 on which a worker's finger can be placed
One or a plurality of 02a are provided along the longitudinal direction of the bar 200. By placing a finger in the groove 202a, slipping of the hand during the cleaning operation can be more effectively prevented.

In the embodiment shown in FIG. 6, a left and right direction in which a worker's finger can be placed on upper and lower pressing surfaces 304 and a flat surface 310 of a solid soap 300 formed in a vertically symmetric and symmetrical octagon. One or more grooves 304a and 310a are formed along the longitudinal direction of the soap bar 300. By placing a finger in the groove 304a , slippage during the cleaning operation can be more effectively prevented.

In the embodiment shown in FIG. 7, the grip surfaces 402,
Both sides of the solid soap 400 on which the 402 is formed are formed in a constricted shape. By forming in this way, it is possible to prevent a worker's finger gripping the grip surfaces 402, 402 from slipping. In the embodiment shown in FIG. 8, the grip surfaces 502,
Projection 502 for hooking a worker's finger on 502
a is one or more (each grip surface 50 in the embodiment of FIG. 8).
2), depressions 504a, 51 into which a fingertip of a worker can be inserted are formed on the pressing surface 504 and the flat surface 510.
One or more (two in the longitudinal direction in the embodiment of FIG. 8) is formed.

In this embodiment, when performing the washing operation, the thumb, middle finger or ring finger is hooked on the projection 502a, and the fingertip of the index finger is inserted into the depression 504a (510a) to hold the solid soap 500. Thereby, the grip surfaces 502, 502
In addition, the finger is less likely to slide on the pressing surface 504 (flat surface 510), and the cleaning operation is facilitated.

Although the preferred embodiment of the present invention has been described, the present invention is not limited to the above embodiment. For example, if there is an effect of preventing slippage, the grooves 202a, 304a, 3 as shown in FIGS.
