Description

The present invention relates to bar soap and bar soap in a container.

Dirt adhering to clothes, shoes and the like includes, for example, mud stains due to adhering mud and stains that are difficult to remove with a washing machine such as colored stains around the collar and cuffs of shirts and the like. Such stains that are difficult to remove are generally partially washed by rubbing solid soap directly on the portion to which the stain is attached.

As a bar soap used for washing clothes and the like by partial washing, a bar soap whose shape has been examined has been proposed from the viewpoint of workability and the like. For example, Patent Document 1 describes a grip surface formed on both sides of a rod-shaped body along the longitudinal direction, a holding surface formed between these two grip surfaces, and between the grip surface and the holding surface. Described is a bar soap having a slope formed in the surface and a retracted portion formed inward of the rod-like body rather than the grip surface. According to Patent Document 1, the cleaning work can be performed without slipping of fingers only by gripping the bar soap with a light force, and an auxiliary anti-slip member such as wrapping paper is not required.

Further, from the viewpoint of preventing the bar soap from being touched directly by hand and making it easier to apply it to the target portion, the bar soap in a container has been proposed. For example, Patent Document 2 describes a solid in a container contained in a container having a substrate that can be attached to the longitudinal end of a columnar solid soap and a friction member that is attached to or integrally formed with the substrate. Soap is listed. Further, Patent Document 3 describes a solid soap in a square columnar container housed in a tubular container having an opening at one end.

According to the bar soap described in Patent Document 1, since the fingertip is placed on the pull-in portion and the bar soap is held on the two surfaces of the grip surface and the presser surface, the finger does not slip easily during the cleaning operation. However, when water adheres to the bar soap, the surface thereof becomes slippery, so that the workability of applying the soap to the object to be cleaned deteriorates. Further, since the bar soap described in Patent Document 2 and Patent Document 3 is used by putting it in a container, partial cleaning can be performed without touching the bar soap, but it is difficult for the operator to get used to it, so that dirt adheres to it. There was a problem in workability when rubbing the bar soap directly on the rubbed part.

Therefore, the subject of the present invention relates to a bar soap that can solve the above-mentioned solution of the prior art.

The present invention provides a columnar bar soap having a polygonal cross-sectional shape of pentagon or more, which is used while being held in a cylindrical container having at least one end open. be.

The present invention also provides a container-filled bar soap in which the bar soap is housed in the tubular container.

According to the bar soap and the bar soap in a container of the present invention, the work of applying the bar soap to the object to be cleaned can be easily and surely performed.

It is called "direction Y".
The cross-sectional shape of the tubular container 2 is the same polygon as the polygon which is the cross-sectional shape of the soap 1. In the tubular container 2 of the present embodiment, the contour of the cross-sectional shape of the cylindrical body 20 is hexagonal, similar to the contour of the cross-sectional shape of the soap 1. The tubular body 20 has a plate-shaped side surface portion 25 that covers the side surface 13 of the soap 1 and a fixing portion 26 that detachably fixes one side surface portion 25. Further, in the tubular body 20, a plurality of plate-shaped side surface portions 25 are connected via a hinge portion 27. Since the plurality of side surface portions 25 fixed in an annular shape form a cylinder and cover the side surface 13 of the soap 1 so as to surround the soap 1, the number of the side surface portions 25 is the same as the number of the side surface 13 of the soap 1. The number is the same. The tubular body 20 covers the soap 1 so that one side surface portion 25 faces the one side surface 13 of the soap 1.
The tubular body 20 according to the present invention includes a bottomless tubular body as in the present embodiment and a bottomed tubular body having an opening at one end and a bottom at the other end.

Further, the tubular body 20 has an inner wall 20a facing the side surface 13 of the soap 1 and an outer outer wall 20b. That is, the inner wall 20a of the tubular body 20 is formed by the inner surface 25a of the side surface portion 25 facing the side surface 13 of the soap 1, and the outer wall 20b of the tubular body 20 is formed by the outer surface 25b of the side surface portion 25. The tubular body 20 of the present embodiment can be expanded from a tubular body to a flat tubular body forming plate-shaped body 200 by releasing the fixing of the fixing portion 26 (see FIG. 4).

The plate-shaped body 200 for forming a tubular body is bent at a hinge portion 27, and a plurality of side surface portions 25 connected in an annular shape form the tubular body 20. Further, as shown in FIG. 4, the tubular body forming plate-shaped body 200 has an end side surface portion 25c forming one end and a fixed side side surface portion 25d to which the fixing portion 26 is connected as the side surface portion 25. Fitting protrusions 25e are provided on the outer surface 25b of the end side surface portion 25c at intervals in the vertical direction X, and holes 26a corresponding to the fitting protrusions 25e are spaced apart in the vertical direction X in the fixing portion 26. It is provided with an opening. In the fixing portion 26, the fitting projection 25e of the end side surface portion 25c is fitted into the hole 26a, and the plurality of side surface portions 25 are fixed in an annular shape and in a detachable manner to form a tubular body 20.
In the tubular container 2 of the present embodiment, the tubular body 200 for forming a tubular body is fixed in a cylindrical shape by fitting the fitting protrusion 25e and the hole 26a, but as another fixing method, a linear container 2 is used. A chuck tape for fitting the convex portion and the concave portion, a mechanical hook-and-loop fastener, an adhesive or the like may be used. The fixing method does not have to be removable.

As shown in FIG. 5, the tubular body 20 of the present embodiment is formed with an accommodating portion 28 for accommodating the soap 1 inside. Both ends of the tubular body 20 are open in the vertical direction X, and the upper cap 22 is engaged with the outer surface 25b of the side surface portion 25 on the one end side thereof. One end side of the tubular body 20 in the vertical direction X, and the side to which the upper cap 22 is engaged is the end side facing the dirty portion in the state of using the solid soap 3a in the container. be. Further, a lower cap 23 is engaged to the other end side of the tubular body 20 in the vertical direction X. The other end side of the tubular body 20 in the vertical direction X, on which the lower cap 23 is engaged, faces the side opposite to the dirty portion when the solid soap 3a in the container is used. It is the end side to be.

In the tubular container 2 of the present embodiment, the soap 1 is arranged on the inner surface 25a side of the side surface portion 25 in the tubular body forming plate 200, and the soap 1 is wound around the plurality of side surface portions 25 to form the tubular body 20. Is assembled, and the soap 1 is accommodated in the accommodating portion 28. Alternatively, the plate-shaped body 200 for forming a tubular body is made into a tubular body 20 by the fixing portion 26, and then the soap 1 is accommodated in the accommodating portion 28. In this way, the soap 1 of the present embodiment is housed in the tubular container 2 and becomes the solid soap 3a in the container. Hereinafter, the solid soap 3a in a container is also simply referred to as the soap 3a in a container.
Further, the tubular container 2 according to the present invention may be used in a cylindrical shape at the time of use as in the present embodiment, as in the tubular container 4 shown in FIGS. 7 and 8 described later. , It may be formed into a cylindrical shape from the beginning.

In the solid soap 3a in a container of the present embodiment, the upper cap 22 is attached to one end side of the tubular body 20 in the vertical direction X, and the lower cap 23 is attached to the other end side. It is stored in a state where both ends of the cylinder 20 in the vertical direction X are closed. It is assumed that the solid soap 3a in a container is stored in a humid place such as a washroom or a bathroom. However, the solid soap 3a in a container of the present embodiment is made of water by the upper cap 22 and the lower cap 23. It is possible to suppress the invasion of soap 1 and the swelling of soap 1 due to moisture.

The container-filled soap 3a of the present embodiment is used in a state where the upper cap 22 is removed from the tubular body 20 and the soap 1 is held in the tubular container 2 having one end opened (see FIG. 6). Further, in the cylindrical container 2, the other end side opposite to the one end side that has been opened may not be opened or may be opened at the time of use. For example, in the tubular container 2 of the present embodiment, the lower cap 23 may be removed from the tubular body 20 to open the other end side at the time of use, and the lower cap 23 is engaged to the other end side. May be the bottom.

As shown in FIG. 6, in the container-containing soap 3a, the soap 1 is partially exposed from the open end side of the tubular container 2, and the exposed portion is rubbed against a place where dirt such as clothing is attached. used. Since the soap 1 is used in a state of being held in a tubular container having at least one end open, it prevents the soap 1 from adhering to the hands of the operator and has a pentagonal cross-sectional shape of the soap 1. Since the above-mentioned polygonal columnar shape makes it possible to easily grip the soap 3a in a container, and it is easy to apply force in the work of pressing the soap 1 against the object to be cleaned while grasping the soap 3a. The work of applying the bar soap can be easily and surely performed. Therefore, the soap 1 of the present invention is excellent in workability when cleaning dirt such as mud dirt which is particularly difficult to remove.
When the cross-sectional shape of the soap 1 is a pentagon or more polygonal shape, dirt adhering to fine parts can be rubbed with the corners 15 of the soap 1, and the soap 1 can be easily applied to the fine parts. ..
Compared to the columnar soap, the soap 1 can be used in a state where the side surface 13 of the soap 1 is exposed from the tubular container 2 so that the soap 1 can be widely applied to the object to be cleaned. can. Specifically, since the side surface 13 of the soap 1 is flat, a wide range of painting work can be easily performed. Further, the soap 1 having the flat side surface 13 can be easily engraved with an arrow or a symbol on the side surface 13 to enhance the distinctiveness, and the soap or soap in a container is compared with the columnar soap. It is hard to roll even if it is placed, it is excellent in handleability at the time of washing, and the soap can be stably transported at the time of manufacturing the soap. The soap with the engraved side surface 13 will be described later.
On the other hand, if the cross-sectional shape of the soap is rectangular or triangular, it is difficult to grasp the soap in the container and it is difficult to apply force when pressing it against dirt. Further, since the angle forming the corner portion is smaller than that of a polygon having a pentagon or more, the corner portion is easily crushed and it is difficult to locally apply soap to a fine portion.

The cross-sectional shape of the soap 1 does not have to be a regular polygon as in the present embodiment, but from the viewpoint of further suppressing the corners 15 from being crushed when rubbing the dirt with the corners 15, and the fine points. From the viewpoint of improving the workability of rubbing dirt with the corners 15, the cross-sectional shape of the soap 1 is preferably a regular polygon of pentagon or more, and more preferably a regular hexagon. Further, the internal angle α (see FIG. 2) of the polygon having the cross-sectional shape of the soap 1 is preferably 100 ° or more, more preferably 110 ° or more, and preferably 150 ° or less, more preferably 140 ° or less. Yes, and more preferably 100 ° or more and 150 ° or less, and more preferably 110 ° or more and 140 ° or less.

The diameter of the circumscribed circle in the cross-sectional shape of the soap 1 is preferably 15 mm or more, more preferably, from the viewpoints of ease of gripping the soap 3a in a container, ease of application to the object to be cleaned, strength of the soap during the application operation, and the like. Is 20 mm or more, preferably 80 mm or less, more preferably 60 mm or less, and preferably 15 mm or more and 80 mm or less, more preferably 20 mm or more and 60 mm or less.
Further, from the viewpoint of easily rubbing the dirt with the soap 1, the soap 1 has a length L5 in the vertical direction X of preferably 50 mm or more, more preferably 80 mm or more, and preferably 200 mm or less, more preferably. Is 180 mm or less, preferably 50 mm or more and 200 mm or less, and more preferably 80 mm or more and 180 mm or less.

The tubular container 2 of the present embodiment has an inner surface 25a corresponding to each of the side surfaces 13 of the soap 1, and the cross-sectional shape of the tubular container 2 is a pentagon or more polygonal shape.
The cross-sectional shape of the tubular container 2 has an inner shape formed by the inner surface 25a of the side surface portion 25 of the tubular container 2 and an outer shape formed by the outer surface 25b of the side surface portion 25 (non-existent). Illustrated). From the viewpoint of holding the soap 1, the inner shape is preferably the same as the cross-sectional shape of the soap 1, and from the viewpoint of ease of gripping by hand and applicability, the outer shape is a cross section of the soap 1. It is preferable that the shape is the same as the surface shape, and from these viewpoints, the outer shape is similar to the inner shape, and further, it is preferable that the shape is the same as the cross-sectional shape of the soap 1. That is, it is preferable that the outer shape of the tubular container 2 is a polygon having the same pentagon or more as that of the bar soap 1.

From the viewpoint of making it easier to grip the container-filled soap 3a and the tubular body 20 surrounding the soap 1, the side surface portion 25 constituting the tubular body 20 is a portion from the tip of the finger to the first joint of the finger, from the first joint to the second joint. It is preferable to design the width L7 (see FIG. 3) so that the side surface portion 25 of the tubular container 2 abuts on the portion up to the joint and each portion from the second joint to the third joint. More specifically, the width L7 of the side surface portion 25 is preferably 15 mm or more, preferably 40 mm or less, and preferably 15 mm or more and 40 mm or less.

Further, from the viewpoint of making it easier to grip the tubular body 20, the diameter of the circumscribed circle of the outer shape in the cross-sectional shape of the tubular container 2 is preferably 20 mm or more, more preferably 30 mm or more, and preferably 90 mm or less, more preferably. Is 70 mm or less, preferably 20 mm or more and 90 mm or less, and more preferably 30 mm or more and 70 mm or less. The diameter of the outer circumscribed circle in the cross-sectional shape of the tubular container 2 is preferably 100% or more, and preferably 110% or less, with respect to the diameter of the inner circumscribed circle in the cross-sectional shape. ..
The container-filled soap 3a is used in a state where the side surface 13 of the soap 1 and the inner wall 20a of the tubular container 2 are in contact with each other. For example, by grasping the tubular body 20 of the tubular container 2, the inner wall 20a of the tubular body 20 and the side surface 13 of the soap 1 come into contact with each other by applying pressure from the outside of the tubular body 20. Therefore, in the tubular container 2, the side surface 13 of the soap 1 and the inner surface 25a forming the inner wall 20a come into contact with each other during use, and the side surface 13 of the soap 1 and the inner surface 25a of the tubular container 2 are in close contact with each other from the beginning. There is something that is there. From the viewpoint of easily contacting the soap 1 and the tubular container 2, the difference between the diameter of the circumscribed circle of the inner shape in the cross-sectional shape of the tubular container 2 and the diameter of the circumscribed circle of the cross-sectional shape of the soap 1 is It is preferably 0 mm or more and 4 mm or less. In addition, as a mode in which the side surface 13 of the soap 1 and the inner wall 20a of the tubular container 2 come into contact with each other, the locking of the soap 1 by the rib 21 described later is also included.

It is preferable that protrusions such as ribs 21 and claws described later are formed. If a protrusion is formed on the inner wall 20a of the tubular body 20, the soap 1 will not easily come off even if one end of the soap 3a in the container is turned downward and tilted greatly, and the soap 1 is strongly pressed against the object to be cleaned. At that time, it is possible to prevent the soap 1 from retreating.
In the tubular container 2 of the present embodiment, a plurality of ribs 21 extending in the lateral direction Y, that is, in the width direction of the side surface portion 25 are provided as protrusions on the inner surface 25a of each of the plurality of side surface portions 25 forming the tubular body 20. The rib 21 bites into or strongly presses against the side surface 13 of the soap 1 to lock the soap 1 to a desired position in the tubular container 2. In the tubular container 2 of the present embodiment, since the plurality of ribs 21 are arranged at intervals in the vertical direction X, the soap 1 can be stably locked. Thereby, even if the length of the soap 1 in the vertical direction X is shortened by the use of the soap 1, the soap 1 can be held so that the soap 1 does not fall off from the cylinder 20. Further, the height of the soap 1 exposed from the cylinder 20 can be adjusted by the plurality of ribs 21 intermittently arranged in the vertical direction X. For example, when the soap 1 is housed in the tubular container 2 in a state of protruding from the end on the upper cap 22 side of the tubular body 20 in the vertical direction X, the end arranged on the lower cap 23 side of the soap 1 When the soap 1 is housed in a state where the rib 21 is provided at an arbitrary position, the length of the soap 1 exposed from the tubular body 20 can be adjusted. By adjusting in this way, even if the soap 1 is shortened, the soap 1 can be easily applied.

The protrusion for locking the bar soap 1 may be a convex portion other than the rib 21, or may be a protrusion having a shape such as a circle or a square when viewed from the radiation direction of the side surface portion, or a protrusion on the side surface portion. It may be a row of protrusions formed intermittently in the width direction. It is preferable that at least one pair or more of the protrusions such as the ribs 21 are formed at positions facing each other with the bar soap sandwiched between them. Further, it may be formed only on a part of the side surface portions arranged in the circumferential direction, and may be formed on every other side surface portion among the side surface portions arranged in the circumferential direction, for example.

The tubular container 2 of the present embodiment forms the tubular body 20 by assembling the tubular container 2 in the expanded state as described above. In the tubular container 2 having such a shape, when the tubular body 20 is gripped, the gripped portion is easily crushed. As a result, the rib 21 can be easily bitten into the soap 1, so that the soap 1 can be stably held in the tubular container 2.

The bar soap cannot be locked to the ribs provided in the tubular container, which may cause the soap to fall out of the tubular container or retreat when strongly pressed against the object to be cleaned. The hardness of the soap 1 by the durometer is preferably 15 or more, more preferably 25 or more, and from the viewpoint of increasing the holding force by the locking protrusions such as ribs and preventing the soap 1 from coming off or retreating when strongly pressed. It is preferably 70 or less, more preferably 60 or less, preferably 15 or more and 70 or less, and more preferably 25 or more and 60 or less.
The hardness of soap 1 by a durometer is measured by the following method.

<Measurement method of hardness with soap durometer>

This durometer is type A. For the measurement, the average value of 5 points is used as the hardness value. For example, the measurement position should be 12 mm or more inside from the edge of the sample, and the distance should be 6 mm or more. The thickness of the sample shall be 6 mm or more. The measurement environment is a temperature of 23 ± 2 ° C. and a humidity of 50 ± 5%.

FIG. 7 is a diagram showing a container-containing soap 3b in a state in which the soap 1 shown in FIG. 1 is housed in a tubular container 4 different from the form shown in FIG. 3, and FIG. 8 is a diagram showing a container-containing soap shown in FIG. 7. It is a cylindrical container 4 of 3b. The tubular container 4 is formed into a cylindrical shape from the beginning, and its outer shape and inner shape, which are the cross-sectional shapes thereof, have the same cross-sectional shape as the soap 1 shown in FIG. The tubular container 4 shown in FIGS. 7 and 8 has an upper cap 42 and a cylindrical body 40 having an opening at one end and a bottom 43 at the other end. The upper cap 42 closes the opening of the tubular body 40 by fitting the inner surface thereof with a part of the outer peripheral surface of the tubular body 40. The tubular body 40 has an engagement portion 44 on the outer peripheral surface thereof, and the engagement portion 44 engages the end portion of the upper cap 42 on the opening side at the time of fitting. As shown in FIG. 8, the tubular body 40 has an accommodating portion 48 for accommodating the soap 1 and a plurality of side surface portions 45 forming an outer peripheral surface of the tubular body 40. The tubular body 40 is provided with a connecting portion 47 that covers the corner portion 15 of the soap 1 between the adjacent side surface portions 45. Further, the tubular body 40 has three sets of a pair of side surface portions 45 facing each other, and a part of the side surface portions 45 is cut out in a U shape on the opening side of the tubular body 40 in each set. A side opening 46 of the same shape and size is formed. On the inner surface of each side surface portion 45 having no side surface opening portion 46, one claw 49 is formed in the vicinity of the opening end portion of the tubular body 40 (see FIG. 8). The claw 49 is a protrusion on which a part of the side surface portion 45 protrudes toward the accommodating portion 48, and locks the soap 1 accommodated in the tubular body 40.
When the pair of side surface portions 45 facing each other have the side surface openings 46, the facing side surface portions 45 of the tubular body 40 are easily crushed and deformed in a direction approaching when the tubular body 40 is gripped, and the side surface openings 46 are easily deformed. The claws 49 provided on the side surface portion 45 having no surface can be easily bitten into the side surface of the soap 1, and the soap 1 can be held more stably. The tubular container 4 shown in FIG. 8 is provided with one claw 49 for each side surface portion 45, and is intermittently provided on the inner surface of each side surface portion 45 in the vertical direction X from the open end portion of the tubular body 40. A plurality of arranged protrusions such as ribs may be formed (not shown). Further, the pair of side surface portions 45 having the side surface openings 46 may also be provided with one or a plurality of protrusions such as ribs on the bottom portion 43 side in the vertical direction X with respect to the side surface openings 46 (not shown). When a plurality of protrusions such as ribs are provided, the distance between these protrusions can be arbitrary, for example, evenly spaced.
As shown in FIG. 8, the tubular container 4 has an opening 43a at the bottom 43 of the tubular body 40. In the soap 3b in a container using such a tubular container 4, the soap 1 can be easily exposed from the tubular body 40 by pushing out the soap 1 from the opening 43a. The bottom portion 43 of the tubular body 40 may or may not have an opening 43a.

FIG. 9 is a diagram showing a container-filled soap 3b in a state in which the soap 1 shown in FIG. 1 is housed in a tubular container 5 different from the above-mentioned form. As described above, the tubular containers 2 and 4 in the containerized soaps 3a and 3b shown in FIGS. 6 and 7 have one end of the tubular container 2 opened during use by removing the upper caps 22 and 42. However, in addition to this, as a cylindrical container in which one end of the tubular container is opened at the time of use, for example, the one shown in FIG. 9 can be mentioned. The tubular container 5 shown in FIG. 9 is in a state in which one end thereof is opened by removing a portion on the outer peripheral surface thereof on the one end side from a position separated by a predetermined width from one end in the vertical direction X. There is. The container-filled soap 3c provided with such a tubular container 5 is used while being held in a state where a part of the soap 1 is exposed from one end side of the tubular container 5. From the viewpoint of easily removing a part of the tubular container 5, it is preferable that the tubular container 5 has a tearing portion having a tearing straightness in the lateral direction Y at one end portion of the vertical direction X. Tear straightness means having a property or structure that is easily torn linearly in a specific direction. As a form having tear straightness, for example, a cutting line such as a half cut that does not penetrate in the thickness direction is provided linearly along a specific direction, or a polymer is oriented so as to be easily avoided in a specific direction by stretching. Examples thereof include a film material that has been made to grow. The tubular container 5 of the present embodiment has a plurality of tear portions at intervals in the vertical direction X so that the soap 1 can be exposed stepwise when the soap 1 is used and shortened in the vertical direction X.
