Description:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to a roll-down toothpaste dispenser, and particularly to a wall-mountable dispenser that instantly puts a desired amount of toothpaste, and the like, at one's fingertips from a conventional toothpaste tube.
2. Description of the Prior Art
Devices are generally known for dispensing toothpaste from a conventional collapsible toothpaste tube. See, for example, U.S. Pat. Nos. 2,670,875, issued Mar. 2, 1954 to R. Perlmutter, 2,717,103, issued Sept. 6, 1955 to G. M. Hill, 2,718,984, issued Sept. 27, 1955 to W. A. Nesser, and 2,742,189, issued Apr. 17, 1956 to R. L. Morrison.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an improved roll-down toothpaste dispenser for dispensing toothpaste, and the like, from a conventional toothpaste tube.
It is another object of the present invention to provide a toothpaste dispenser having a simple, yet rugged and reliable ratchet gear actuating mechanism.
It is still another object of the present invention to provide a toothpaste dispenser into which a conventional tube of toothpaste is easily insertable.
These and other objects are achieved according to the present invention by providing a toothpaste dispenser having: a tube receiving housing provided with at least one slot; a tube winding spindle arranged in the housing and having a portion thereof extending out of the housing through the slot; and a gear mechanism arranged outside the housing for translating rotary motion imparted to the spindle into linear motion in a predetermined direction along the slot. Advantageously, the housing is provided with a pair of opposed slots, and longitudinally spaced ends of the spindle extend out of the housing through the slots. In this instance, similar gear mechanisms will be provided at either end of the spindle.
A preferred gear mechanism according to the present invention includes: cogs disposed on an outer surface of the housing along opposite edges partially defining the slot or slots; a spool for each slot provided, the spool mounted on the winding spindle and provided with teeth arranged on a face of the spool and arranged for engaging the cogs and forming a ratchet gear mechanism therewith; and a spring associated with each spool for biasing the spool toward the housing and causing the teeth of the spool to engage with the cogs.
The neck of a conventional toothpaste tube is insertable into a hole passing through a projection provided in an end surface of the housing. This projection is advantageously provided with a head over which a cap is rotatably mounted. By arranging the hole in the projection in offset relationship with respect to the axis of rotation of the cap, and by further providing an aperture in the cap which is also offset with respect to the axis of rotation of the cap, a simple, yet effective, valve is provided for selectively blocking emission of toothpaste from the dispenser. In this manner, a hygienic device is provided.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now more particularly to FIGS. 1 through 3 of the drawings, a dispenser 10 according to the present invention for dispensing toothpaste, and the like, from a collapsible tube 12, such as are conventional and commonly used in the marketing of toothpaste, has a tube receiving housing 14 provided with a pair of opposed slots 16 and 18. As can be readily appreciated from the drawings, slots 16, 18 extend longitudinally down opposed sides of housing 14. A tube winding spindle 20 is arranged in housing 14, and has end portions thereof extending out of housing 14 through slots 16, 18. A gear arrangement 22 to be described in detail below is arranged outside housing 14 adjacent each end portion of the spindle 20 for translating rotary motion imparted to spindle 20 into a linear motion in a predetermined direction along the slots 16, 18. As illustrated, this linear motion will be downwardly along the slots 16, 18.
Gear arrangement 22 includes a plurality of cogs 24 in the form of wedge-shaped teeth slanted in the normal upward direction of orientation of housing 14. These cogs 24 are provided on walls 26 and 28 in which slots 16, 18 are provided. Each arrangement 22 has a spool 30, 32 mounted on an associated end portion of spindle 20 and provided with teeth 34 arranged on a face of the respective spool 30, 32 for engaging associated cogs 24 and forming a ratchet gear mechanism therewith. Spring arrangements 36 are provided for biasing the spools 30, 32 toward housing 14 so as to cause teeth 34 to engage with cogs 24.
Spools 30, 32 are retained on spindle 20 by the provision on spindle 20 of a head 38, preferably knurled, and the like, for facilitating turning of spindle 20, and a cap nut 40 which threadedly engages with the end of spindle 20 spaced from that end wherein head 38 is disposed. A longitudinally extending slot 41 provided in spindle 20 receives the winding end of tube 12 for causing the tube to be wound as spindle 20 is moved downwardly along slots 16, 18. As can be appreciated from the drawings, spindle 20 may be formed by a pair of spaced, parallel rods, and the like, which define slot 41.
Spring arrangements 36 each includes a, for example, conventional coiled compression spring 42 arranged in hollow spool 30, 32 for partially abutting the apertured wall of the associated spool and one flange of a bushing 44 arranged extending into spool 30, 32 and provided with a pair of flanges 46 and 48. One flange, flange 46 as illustrated, extends into housing 14 and bridges an associated one of the slots 16, 18, while the bushing 44 itself extends through the associated slot 16, 18 and into the associated spool 30, 32. The other of the flanges, flange 48 as illustrated, forms one abutting surface for spring 42 in order to bias spool 30, 32 toward housing 14. In this manner, bushing 44 functions both as a bearing and as part of spring arrangement 36.
A rear wall 49 of housing 14 is selectively arranged contacting a housing wall 50, and the like, and mounted to wall 50 as by, for example, conventional screws 52. Upper end 53 of housing 14 is selectively removable for facilitating access to the interior of the housing.
A projection 54 having a head 56 is provided on the lower end wall 58 of housing 14. This wall 58, as can be seen from FIGS. 2 and 3 of the drawings, is oriented perpendicularly to and arranged extending between walls 26 and 28. A hole 60 is provided which passes through projection 54 in offset relationship with respect to head 56 thereof for receiving an outlet neck 62 of tube 12. A cap 64 is provided with an eccentric aperture 66 (FIG. 4), and is rotatably arranged on head 56 of projection 54 for permitting aperture 66 to be selectively rotated into alignment with hole 60. In this manner, a reliable yet simple and efficient valve is formed. As can be appreciated from FIG. 4, wall 58 is constructed in a manner similar to end wall 53 so that same will be selectively removable from housing 14 for facilitating access to the interior of the housing.
As can perhaps best be seen from FIG. 3 of the drawings, the embracing of spools 30, 32 by head 38 and nut 40, it being appreciated that apertures are provided in spools 30, 32 that permit spindle 20 to pass through same, causes spools 30, 32 to rotate whenever spindle 20 is rotated. In this manner, the teeth 34 provided on spools 30, 32 will engage with cogs 24 and draw spindle 20 downwardly along slots 16, 18 in ratchet-like fashion. Springs 42 will cause teeth 34 to be resiliently biased against cogs 24 so that the teeth will pass over the cogs in one direction only. Further, the springs assure that spindle 20 will be retained in any desired position with respect to slots 16, 18.
It may be desirable to provide the outermost end surfaces of spools 30, 32 and the adjacent, abutting surfaces of head 38 and nut 40 with friction-increasing material in order to assure that spools 30, 32 will rotate with spindle 20.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now more particularly to FIGS. 1 through 3 of the drawings, a dispenser 10 according to the present invention for dispensing toothpaste, and the like, from a collapsible tube 12, such as are conventional and commonly used in the marketing of toothpaste, has a tube receiving housing 14 provided with a pair of opposed slots 16 and 18. As can be readily appreciated from the drawings, slots 16, 18 extend longitudinally down opposed sides of housing 14. A tube winding spindle 20 is arranged in housing 14, and has end portions thereof extending out of housing 14 through slots 16, 18. A gear arrangement 22 to be described in detail below is arranged outside housing 14 adjacent each end portion of the spindle 20 for translating rotary motion imparted to spindle 20 into a linear motion in a predetermined direction along the slots 16, 18. As illustrated, this linear motion will be downwardly along the slots 16, 18.
Gear arrangement 22 includes a plurality of cogs 24 in the form of wedge-shaped teeth slanted in the normal upward direction of orientation of housing 14. These cogs 24 are provided on walls 26 and 28 in which slots 16, 18 are provided. Each arrangement 22 has a spool 30, 32 mounted on an associated end portion of spindle 20 and provided with teeth 34 arranged on a face of the respective spool 30, 32 for engaging associated cogs 24 and forming a ratchet gear mechanism therewith. Spring arrangements 36 are provided for biasing the spools 30, 32 toward housing 14 so as to cause teeth 34 to engage with cogs 24.
Spools 30, 32 are retained on spindle 20 by the provision on spindle 20 of a head 38, preferably knurled, and the like, for facilitating turning of spindle 20, and a cap nut 40 which threadedly engages with the end of spindle 20 spaced from that end wherein head 38 is disposed. A longitudinally extending slot 41 provided in spindle 20 receives the winding end of tube 12 for causing the tube to be wound as spindle 20 is moved downwardly along slots 16, 18. As can be appreciated from the drawings, spindle 20 may be formed by a pair of spaced, parallel rods, and the like, which define slot 41.
Spring arrangements 36 each includes a, for example, conventional coiled compression spring 42 arranged in hollow spool 30, 32 for partially abutting the apertured wall of the associated spool and one flange of a bushing 44 arranged extending into spool 30, 32 and provided with a pair of flanges 46 and 48. One flange, flange 46 as illustrated, extends into housing 14 and bridges an associated one of the slots 16, 18, while the bushing 44 itself extends through the associated slot 16, 18 and into the associated spool 30, 32. The other of the flanges, flange 48 as illustrated, forms one abutting surface for spring 42 in order to bias spool 30, 32 toward housing 14. In this manner, bushing 44 functions both as a bearing and as part of spring arrangement 36.
A rear wall 49 of housing 14 is selectively arranged contacting a housing wall 50, and the like, and mounted to wall 50 as by, for example, conventional screws 52. Upper end 53 of housing 14 is selectively removable for facilitating access to the interior of the housing.
A projection 54 having a head 56 is provided on the lower end wall 58 of housing 14. This wall 58, as can be seen from FIGS. 2 and 3 of the drawings, is oriented perpendicularly to and arranged extending between walls 26 and 28. A hole 60 is provided which passes through projection 54 in offset relationship with respect to head 56 thereof for receiving an outlet neck 62 of tube 12. A cap 64 is provided with an eccentric aperture 66 (FIG. 4), and is rotatably arranged on head 56 of projection 54 for permitting aperture 66 to be selectively rotated into alignment with hole 60. In this manner, a reliable yet simple and efficient valve is formed. As can be appreciated from FIG. 4, wall 58 is constructed in a manner similar to end wall 53 so that same will be selectively removable from housing 14 for facilitating access to the interior of the housing.
As can perhaps best be seen from FIG. 3 of the drawings, the embracing of spools 30, 32 by head 38 and nut 40, it being appreciated that apertures are provided in spools 30, 32 that permit spindle 20 to pass through same, causes spools 30, 32 to rotate whenever spindle 20 is rotated. In this manner, the teeth 34 provided on spools 30, 32 will engage with cogs 24 and draw spindle 20 downwardly along slots 16, 18 in ratchet-like fashion. Springs 42 will cause teeth 34 to be resiliently biased against cogs 24 so that the teeth will pass over the cogs in one direction only. Further, the springs assure that spindle 20 will be retained in any desired position with respect to slots 16, 18.
It may be desirable to provide the outermost end surfaces of spools 30, 32 and the adjacent, abutting surfaces of head 38 and nut 40 with friction-increasing material in order to assure that spools 30, 32 will rotate with spindle 20.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
