LATHERER FOR SOAP mourn Filed June 9, 1972 I 2 Sheet-8heet 2 United States Patent US. Cl. 252-359 E 2 Claims ABSTRACT OF THE DISCLOSURE A latherer for a liquid soap is disclosed. The latherer includes a casing for accommodating the mechanism of the latherer therewithin. A nozzle is mounted on the casing at the upper opening thereof. In the casing a stirring chamber is located and the stirring chamber accommodates a rotor having a blade for stirring a liquid soap. A motor for driving the rotor and a tank for supplying a soap liquid are mounted on the casing. The tank communicates with the stirring chamber through a passage. A valve is provided within the passage and a switch is provided on the casing the switch being adapted to open and close the valve.
The present invention relates to a handy latherer, more particularly to a latherer for stirring soap liquid to form creamlike soapsuds which may spout therefrom.
A first object of the present invention is to provide a latherer by which it is feasible to lather a required quantity of soap liquid thoroughly.
A second object of the present invention is to provide a latherer with which soapsuds may be obtained easily and the body of which may be readily held and maneuvered.
These and other objects are accomplished by the parts, improvements, combinations and arrangements comprising the present invention, a preferred embodiment of which is shown by way of example in the accompanying drawings, and hereinafter described in detail.
In the drawings, FIG. 1 is a vertical section of the latherer according to the present invention.
FIG. 2 is a section of the part of the stirring chamber showing the relation between the switch and the valve and the condition before pushing the switch.
FIG. 3 is the same section as FIG. 2 but shows the condition after pushing the switch is shown.
FIG. 4 is a plan view of FIG. 2.
In the drawing, A is the latherer. An upper casing 1, is provided at the upper portion of the latherer. A nozzle 2 is attached to the upper portion of the casing 1, said nozzle 2 having a nozzle hole 3 having an elliptic crosssection. The edge 4 of the nozzle hole 3 forms a concave surface as shown.
The upper end portion of the cylindrical wall 6 which forms stirring chamber 5, is positioned against the lower portion of the inner wall of the nozzle hole 3. An annular ridge 7 is provided on said cylindrical wall 6 and protrudes along the inner wall at the upper portion thereof. The inside of the cylindrical wall 6 forms a stirring chamber and within the stirring chamber 5 a cylindrical rotor 9 is provided. The rotor 9 is rotatably positioned coaxially within the stirring chamber 5. On the outer periphery of the rotor 9 a helical stirring blade 10 is formed and a uniform clearance 11 is left between the edge of the blade 10 and the inner periphery of the cylindrical wall 6. A small space is left between the outer peripheral surface of the blade and the annular ridge 7 on the cylindrical wall 6. 12 is a shaft of the rotor 9 and the shaft 12 is connected to the driving shaft of the motor 13 through the wall 8 at the lower end of the stirring chamber 5. The wall 8 maintains the bottom of the stirring chamber 5 in a liquid tight condition.
3,814,697 Patented June 4, 1974 The motor 13 is secured to the support member 14 fixed to the lower end of the upper casing 1, and cylindrical wall 6 is fixed to the wall 8 and also mounted securely on the support member 14 by means of bolts. 15 is a tank for soap liquid which is screwed securely onto the lower end of the support member 14. The upper periphery of the tank 15 is screwed onto the lower edge of the support member 14, and forms a liquid tight seal and on the lower central portion thereof a valve box 16 is provided for injecting soap liquid thereinto, and said valve box is provided with a valve body 35 therein. 17 is an inner cover covering the lower opening of the tank 15, the inner cover 17 being tightly and removably fitted to the lower edge of the tank 15.
A lower casing 18 is scewed onto the upper casing 1, and there is a slight separation between the inner periphery of said lower casing 18 and the outer periphery of said tank 15. At the lower end of the lower casing 18 a bottom cover 19 is removably screwed onto the screw thread provided on the outer periphery at the lower end portion of the tank 15. An electric cord 20 depends from the bottom cover 19.
On the cylindrical wall 6 defining the stirring chamber 5 a soap liquid inlet 21 is provided. The inlet communicates with a hollow rod 23 through a pipe 22 of a resilient material, the rod being slidably mounted and extend ing through the through-hole 26 provided on the wall 8. The rod has a stopper 28 at the upper portion thereof consisting of two spaced rings and is adapted to slide in the through-hole of the wall 8 by means of a lever 25 engaging said stopper 28.
A reservoir 29 is provided below the wall 8 and the reservoir communicates with the tank 15 through a pipe 27. The reservoir communicates with the rod 23 through a through-hole 30 provided on the lower portion of the rod when the rod is lowered by the lever 25 of the switch 24.
Accordingly, to introduce soap liquid from the tank 15 into the stirring chamber 5, latherer A is first turned upside down to allow the liquid in the tank to flow into the reservoir 29 through the pipe 27. Then, the switch 24 is pushed against the spring 32 into the latherer and pivots about shaft 31. Since the spring 32 acts also as a terminal lead from the electric cord 20, when the switch 24 is depressed the spring 32 and the other terminal 33 are brought into contact and the rotor 9 with the helical blade 10 in the stirring chamber is thus activated and rotated by the motor 13.
When the switch 24 is pushed further into the latherer, as shown in FIG. 3, the end portion of the valve rod 23 is projected into the liquid reservoir 29 by means of the lever 25 of the switch engaged with the stopper 28, and the soap liquid in the tank flows into the stirring chamber through the pipe 27, the reservoir 29, the through-hole 30, the valve rod 23, the pipe elbow 22 and the inlet 21, seriatim.
As shown in FIG. 1, the valve box 16 is mounted on the interior of an opening 34 of the tank 15 and said valve box includes a valve body 35 and a ball 36, said valve body being slidably supported by the cylindrical wall of the lower opening 34 of said valve box, and the lower surface of said valve body being adapted to fit tight- 1y against the opening 34 in the state as shown in FIG. 1. A plurality of slits 37, 38 are provided around the valve box and the cylindrical wall of the lower opening 34 respectively.
The latherer according to the present invention is constructed as mentioned above and when the latherer is used, bottom cover 19 is initially removed from the body and the inner cover 17 engaged with the bottom cover 19 is also removed. Thereafter, the body is turned upside down and soap liquid is injected thru the opening 34 of the tank 15 by means of a soap liquid injection nozzle.
Valve body 35 is slidably fit within the opening 34, and when it is pushed by the injecting nozzle, the valve body 35 is slid slightly inwardly along the cylindrical wall of the opening 34. As the cylindrical wall is provided with several slits 37, soap liquid is injected into the tank thru said slits 37 through the slits 38 of the valve box 16. After the bottom cover 19 is screwed onto the casing 18, the terminal plug of the electric cord is put in the plug socket and the switch 24 is pushed into the body of the latherer, whereby the rotor 9 is rotated by the motor 13 and the soap liquid flows into the stirring chamber from the tank 15.
The soap liquid in the stirring chamber moves toward the top nozzle along the inner wall of the stirring chamber by means of centrifugal force while being stirred with the helical blade 10. However, as the annular ridge 7 is provided on the terminal portion of the cylindrical wall 6, the soap liquid which is not thoroughly lathered and is flowing down along the inner wall of the stirring chamber is blocked by the annular ridge, thereby enabling the soap liquid to become fully lathered and also preventing the unlathered soap from dripping from the nozzle.
The stirring of the soap liquid causes the volume thereof to expand and fully lathered soapsuds spout from the nozzle hole 3 through the clearance 11 due to the expansion pressure of the expanded volume of the lathered soap. The clearance modifies the spouting pressure of the soapsuds and makes it uniform, and thereby soapsuds are evenly spouted from the nozzle. Since the terminal edge of the nozzle has a concave shape the soap can flow out from the nozzle smoothly even when the latherer is being directly applied to a users face.
What is claimed is:
1. A latherer comprising a casing, a stirring chamber within said casing, a rotor with a helical blade mounted rotatably within said stirring chamber, a motor mounted on said casing and connected with said rotor, an electric circuit operatively coupled to said motor for selective activation thereof a tank for a soap liquid mounted in said casing, a nozzle located adjacent and communicating with said stirring chamber, a passageway connecting said tank and said stirring chamber for supplying said stirring chamher with a soap liquid from said tank, a valve provided within said passageway and comprised of a hollow rod open at one end and sealed at the other end and having an aperture in the periphery thereof in the vicinity of said sealed end, said rod slidably mounted in said passageway and adapted to have its apertured end extended into and retracted from an enlarged portion of said passageway whereby the passageway may be opened when the rod is projected into the enlarged portion and closed when the rod is withdrawn to the extent that the peripheral aperture is not within said portion, and a switch mounted on the casing, said switch being adapted to open and close said valve, and being included in said electric circuit in series whereby opening and closing said valve activates and deactivates said motor in a synchronous manner.
