JP5622317B2 - Liquid soap dispenser - Google Patents

Description

  The present invention relates to a dispenser for liquid soap that contains liquid soap such as liquid hand soap and body soap, and can be used by being shaken out by hand and used in an appropriate amount.

Conventionally, when washing the body during hand washing or bathing, solid hand soap or liquid soap contained in a container with a pump is used.
If a solid hand soap is placed in a soap tray or a soap box, it will absorb moisture and melt into the mud, or the soap that has melted from the drain holes at the bottom of the soap will flow out, making the surroundings unclean. In addition, there was a problem that it became harder to grasp by hand because it became smaller and collapsed during use.

  In addition, liquid soap contained in a container with a pump is difficult to press the pump when taking out the soap solution. In the meantime, the soap solution hardened and accumulated at the outlet of the pump, causing clogging.

  Therefore, in order to solve such problems, for example, a dispenser for liquid soap as described in Patent Document 1 has been proposed. The dispenser disclosed in this document has a case with a shape and size of a solid soap suitable for holding between hands when a user wash hands, and soap liquid is contained inside the case. ing.

  The case is provided with an exit orifice that is always closed by a ball biased by a spring, and when the user rubs and pushes a ball partially protruding from the exit orifice onto the case surface, The outlet orifice is opened and the soap solution inside the case is removed from the exit orifice as the ball rotates. When the user releases the ball, the ball closes the exit orifice by the spring's restoring force and the soap solution flows out. Has come to stop.

Special table 2010-526622

  As described above, the dispenser for liquid soap described in Patent Document 1 needs to push the ball closing the outlet orifice by hand when taking out the soap solution, so that the body is washed when taking a bath. In the case, the soap solution could not be used directly on the towel or sponge.

  In addition, since the spring that urges the ball and the parts for guiding and holding the ball are built inside the case containing soap liquid, the structure becomes complicated and the soap liquid stays in the case for a long time. If it stays, the soap solution is deposited and adhered around the spring and the outlet orifice may be clogged.

  Therefore, the present invention solves the problems of the conventional liquid soap dispenser as described above, and can easily take out an appropriate amount of soap solution by simply shaking it with one hand. An object of the present invention is to provide a hygienic liquid soap dispenser that can reliably stop leakage and has a simple structure and is less likely to cause clogging of soap liquid.

  In order to solve the above-mentioned problems, the dispenser for liquid soap according to the present invention has an upper half portion whose center upper surface is formed by a medium-high convex curved surface, and a peripheral portion curves downward, and a peripheral portion of the upper half portion It consists of a lower half part composed of a continuous curved surface that is smoothly continuous, further curved inward at the lower part toward the center, and recessed at the center on the lower surface above its periphery. The hand soap type dispenser main body of a size that can be held with one hand, having an opening communicating with the storage chamber at the center of the lower surface, and disposed in the dispenser main body. A valve chamber that communicates with the valve chamber; a cap body that includes a base portion that seals the opening continuously below the valve chamber; and a spherical valve body that is movably incorporated in the valve chamber in a vertically movable manner. The lower surface of the base part is At least one discharge hole communicating with the valve chamber is formed in the lower surface of the cap portion so as to be positioned above the periphery of the center portion of the lower surface of the pencer body, and around the opening portion of the discharge hole in the valve chamber. A seating surface for blocking the flow of the soap liquid from the storage chamber to the discharge hole when the valve body is seated, and the inner wall surface of the valve chamber has a gap through which the soap liquid can pass between the valve body and the periphery. And at least a lower portion of the inner wall surface is formed of a curved surface or a conical surface that guides the seat body toward the seating surface when the valve body moves downward. The valve body is set to a size that can prevent leakage from the discharge hole due to the gravitational action of the soap solution by the surface tension of the soap solution when it is left facing down, and the dispenser body is shaken up and down. Up and down movement More, while soap solution is limited to stirred and outflow, in which so as to be swung dropwise from the discharge hole.

  In the dispenser for liquid soap according to the present invention, the dispenser body is made of metal, and defines a resonance chamber separated from the storage chamber by a bowl-shaped partition wall, and one end of the resonance chamber is in the resonance chamber. A sound ring made of the same material as the dispenser body in a horizontal loop shape welded to the inner wall of the resonance chamber and the other end being a free end, and when the dispenser body is swung inside the sound ring, It is desirable to incorporate a sound bulb that strikes the ring and produces sound. It is also desirable that the dispenser body is made by casting titanium or a titanium alloy.

  According to the dispenser for liquid soap according to the invention described in claim 1, each time the dispenser main body is held in one hand and shaken up and down, the soap solution can be sprinkled out from the discharge hole. It is possible to wash the hand using the same as a solid hand soap by adhering the taken soap solution to the outer surface of the dispenser body.

  Therefore, the inconvenience that the size becomes small with use and becomes difficult to hold, or deforms or collapses due to moisture and cannot be used until the end, as in the case of a conventional solid hand soap, can be solved. Furthermore, the soap solution can be used by directly sprinkling it on a towel or sponge.

  In addition, the amount of soap liquid spouted from the discharge hole is limited by the spherical valve body that moves up and down in the valve chamber, and the soap liquid is spouted out from the discharge hole, so a large amount of soap liquid is wasted. Can be prevented. Furthermore, since the amount of soap solution used can be reduced, it is possible to contribute to the reduction of environmental pollution of rivers and the like due to drainage.

  Moreover, since the soap liquid in the valve chamber is agitated by moving the valve body up and down, there is no possibility that the soap liquid will harden and clog the discharge hole, and the dispenser body is left still with the base side facing downward. In the state, since the soap liquid leaks from the discharge hole can be surely stopped by the surface tension of the soap liquid, the area around the place where the dispenser is placed can be kept hygienic.

  According to the dispenser for liquid soap according to the invention described in claim 2, each time the dispenser body is shaken during use, the sounding ball collides with the sounding ring and vibrates, and this vibration is transmitted to the resonance chamber. If you do, it will be expanded to a high and clear sound like a bell, and it will be pronounced from the dispenser body, so you can relax your mood when taking a bath, etc. Can be confirmed by counting.

  According to the dispenser for liquid soap according to the invention described in claim 3, the dispenser main body is light and strong and excellent in corrosion resistance, and is less likely to cause metal allergy. A titanium oxide film is always formed on the surface of the titanium alloy, and this acts as a photocatalyst that generates active oxygen when exposed to light. It is done.

  Furthermore, a decorative effect can be obtained because various colors can be easily developed depending on the thickness of the titanium oxide film formed on the surface of the dispenser body.

As shown in the figure, a liquid soap dispenser (hereinafter referred to as a dispenser) 1 includes a solid hand soap dispenser main body 2 having a size that can be held with one hand.

  The dispenser main body 2 is integrally formed by vertically butting the peripheral edge surfaces of the upper half part 3 and the lower half part 4 made of titanium castings in a plan view and welding them all around the circumference. A storage chamber 5 in which the soap solution S is accommodated is formed inside.

  Moreover, in the thing of this embodiment, the upper surface of 3 A of center parts of the upper half part 3 is comprised by the medium-high dome shape convex curve. The central part 3A is manufactured separately from the peripheral part 3B, and after being welded to the peripheral part 3B, the center part 3A is polished so that both are smoothly continuous.

  Below the central portion 3A, a bowl-shaped partition wall 3C is provided, and the periphery of the partition wall 3C is continuous with the peripheral edge portion 3B at a position near the welded portion w between the peripheral edge portion 3B and the central portion 3A. A resonance chamber 6 described later is formed between the central portion 3A and the partition 3C.

  On the other hand, the lower half portion 4 of the dispenser main body 2 has a shape in which the lower portion is curved inwardly toward the center and the lower surface of the central portion 4A is recessed upward from the periphery thereof. An opening 4B communicating with the chamber 5 is opened. In the present embodiment, a plurality of hemispherical protrusions 4C, which will be described later, are formed in two rows concentrically around the central portion 4A.

  The opening 4B is hermetically sealed by a cap portion 7A of the plug 7. FIG. 5 is a partial longitudinal sectional view of the plug body 7, and FIG. 6 is a perspective view thereof. As shown in these drawings, the plug body 7 is applied to the periphery of the opening 4B on the lower surface of the central portion 4A. It is composed of a bowl-shaped base portion 7A that is in contact with a cylindrical valve chamber 7B that is continuous thereabove, and is integrally formed of a flexible silicon rubber material that easily elastically deforms.

  In addition, an annular bead portion 7 </ b> C is formed in the plug body 7 over the entire outer peripheral surface of the valve chamber 7 </ b> B. When the plug body 7 is inserted into the opening 4B, the bead portion 7C is located at a position where the bowl-shaped base portion 7A is in close contact with the periphery of the opening 4B of the dispenser body 2 as shown in FIG. The stopper 7 is fixed by elastically engaging with the inner peripheral edge.

  When removing the plug 7 from the opening 4B, the bead 7C is elastically deformed and disengaged from the opening 4B by pulling the nail around the outer periphery of the bowl-shaped base 7A. The plug 7 can be easily removed from the opening 4B.

  As shown in FIG. 5, in the present embodiment, the inner wall surface 7D of the valve chamber 7B of the plug 7 is formed in a spherical shape, and the inside of the valve chamber 7B defined by the inner wall surface 7D. A spherical valve body 8 is incorporated in the space so as to be freely movable. Here, a stainless sphere having an outer diameter of 3 mm is used for the valve body 8. The material of the valve body 8 is not limited to this, and titanium, glass, ceramic, or the like may be used.

  On the other hand, a communication hole 7E having a diameter smaller than that of the valve body 8 is formed in the central portion of the upper end surface of the valve chamber 7B so as to communicate the storage chamber 5 of the dispenser main body 2 with the inside of the space. A discharge hole 7F having a smaller diameter than the valve body 8 is formed in the center of the lower surface of the valve body 8 and communicates with the space in the valve chamber 7B. In addition, the hole diameter of the discharge hole 7F is set to a size that can prevent the soap liquid from leaking due to the gravitational action by its surface tension.

  Further, a seating surface 7G of the valve body 8 is formed at the peripheral edge portion that opens into the valve chamber 7B of the discharge hole 7F, and as shown in FIG. 1, the dispenser main body 2 is placed with the base portion 7A directly below. In this state, the valve body 8 is guided by the spherical inner wall surface 7D, moves downward due to its own weight, is seated on the seating surface 7G, and the discharge hole 7F is closed.

  When the dispenser 1 configured as described above is grasped by hand and shaken up and down, the valve body 8 moves up and down in the valve chamber 7B after leaving the seating surface 7G. As a result, the interior of the storage chamber 5 and the discharge hole 7F are intermittently communicated, and the soap solution is spouted out from the discharge hole 7F. At this time, since the soap solution in the valve chamber 7B is agitated by the vertical movement of the valve body 8, it is possible to prevent the soap solution from being hardened and clogged in the vicinity of the discharge hole 7F.

  The soap solution dispensed from the dispenser 1 can be received and used with a hand or a towel. At this time, since the dispenser body 2 has a solid hand soap shape, it can be used in the same manner as an actual hand soap.

  In particular, in the present embodiment, since the soap liquid is held between the plurality of protrusions 4C formed on the bottom surface of the dispenser body 2, the foaming of the soap liquid can be improved. In addition, you may form the protrusion 4C in the whole dispenser main body 2. FIG. In addition, when using for hair washing, an appropriate amount of liquid shampoo can be sprinkled over the head hair by using a shampoo for the soap solution and shaking the dispenser 1 over the head.

  On the other hand, in the dispenser 1 of the present embodiment, as described above, the resonance chamber 6 is formed inside the upper half 3 of the dispenser body 2 and separated from the storage chamber 5 by a bowl-shaped partition wall. In the resonance chamber 6, there is incorporated a loop-like sound ring 9 having one end welded to the inner wall of the resonance chamber 6 and the other end being a free end. When the dispenser main body 2 is swung, a sounding ball 10 is incorporated that causes the sounding ring 9 to collide and sound.

Therefore, every time the dispenser 1 is shaken with the hand, the sound generation ring 9 vibrates due to the collision of the sound generation ball 10, and when this vibration is transmitted to the resonance chamber, it becomes high and clear like a bell. Since the sound is magnified and sounded from the dispenser body, an additional effect of relaxing the mood can be obtained at the time of use such as bathing, and the amount of soap liquid to be shaken out can be confirmed by counting the sound.
In the present embodiment, the sound generation ring 9 uses the same titanium material as the dispenser main body 2 and the sound generation ball 10 uses a stainless steel ball in order to improve the sound.

  Next, FIG. 7 is a longitudinal sectional view of a plug used in another embodiment of the dispenser for liquid soap of the present invention, FIG. 8 is a perspective view thereof, and the plug 11 shown in these drawings is 1 is mounted in the opening 4B of the dispenser main body 2 shown in FIG. 1 in the same manner as the plug 7 and is made of silicon rubber similar to the plug 7 and has a periphery of the opening 4B on the lower surface of the central portion 4A. 11A, and a cylindrical valve chamber 11B that is continuous thereabove.

  Further, when the plug body 11 is inserted into the opening 4B in the same manner as the plug body 7 described above, an annular bead portion 11C formed on the outer peripheral surface of the valve chamber 11B is connected to the inner peripheral edge of the opening 4B. It is elastically engaged and fixed in a liquid-tight manner.

The inner wall surface 11D of the valve chamber 11B is formed in a tapered shape with a narrower bottom, and the upper end opening 11E of the space in the valve chamber 11B surrounded by the inner wall surface 11 is the upper end surface of the valve chamber 11B. The cap is covered with a cap-shaped resin mesh lid 12 that is fitted into the cap.
The mesh lid 12 covers the opening 11E, and a mesh portion 12A through which soap solution can flow, and an edge portion 12B that elastically engages with an engagement step portion 11F formed at the outer periphery of the upper end of the valve chamber 11B. Is integrally molded.

  In addition, a spherical valve element 13 is provided in the space in the valve chamber 11 so as to be freely movable, and the mesh lid 12 restricts the upward movement of the valve chamber 11. Further, a spherical seating surface 11G adapted to the valve body 13 is formed continuously to the lower end portion of the tapered inner wall surface 11D. Here, the valve body 13 is a stainless sphere having an outer diameter of 8 mm. Note that titanium, ceramic, glass, or the like may be used as the material of the valve body 13 as in the valve body 8 described above.

  On the other hand, a concave portion 11H communicating with the space inside the valve chamber 11 is formed in the central portion on the lower surface side of the base portion 11A, and a porous plate 14 having a plurality of discharge holes 14A is fitted on the lower surface of the concave portion 11H. It is worn. In the present embodiment, the porous plate 14 is made of a hard resin, and the hole diameter of the discharge hole 14A is set to a size that can prevent leakage due to the gravitational action of the soap liquid by its surface tension.
