Application January 26, 1955, Serial No. 484,145
Claims. (Cl. 222-103) This invention relates to improved means for dispensing the contents of collapsible tubes.
The primary object of the invention is to provide a convenient, completely portable and sanitary dispenser for collapsible tubes which advances along the tube during its dispensing cycle and dispenses a predetermined amount of contents from the collapsible tube during each cycle of operation thereof.
A further object of the invention is to provide a simply constructed, easily manufactured and assembled, and convenient-to-use dispenser for collapsible tubes that readily receives the butt end of the tube and advances therealong responsive to a simple lever operation of its dispensing cycle during which a predetermined amount of contents is ejected from the head of the tube.
Other objects of the invention will become apparent by reference to the following detailed description taken in connection with the accompanying drawings, in which:
Fig. 1 is a cross sectional view of a collapsible tube dispenser embodying the invention taken on the line 1--1 of Fig. 2.
Fig. 2 is a side elevational view of the dispenser shown in Fig. 1 with parts successively broken away to show the construction clearly.
Fig. 3 is a top plan view with parts successively broken away.
Fig. 4 is a bottom elevational view with the various elements of the mechanism shown in dotted lines in the upper half thereof only, the construction being symmetrical about the longitudinal center thereof.
Fig. 5 is a fragmentary cross sectional view of the hous ing or main body member taken on line 55 of Fig. 6.
Fig. 6 is a bottom view of the housing or main body member.
Fig. 7 is an elevational view of one of the operating levers.
Fig. 8 is a view part in side elevation and of the operating lever shown in Fig. 7.
Fig. 9 is a top plan view of one of the rocker cams employed to actuate the tube grip blocks.
Fig. 10 is an end elevational view of the rocker cam shown in Fig. 9.
Fig. 11 is a rear elevational view of a tube grip block.
Fig. 12 is an end elevational View of the tube grip block shown in Fig. 11.
Fig. 13 is an elevational view of the tube stop employed to hold the tube into the position to which it is pulled by the tube grip blocks responsive to manual squeezing of the operating levers.
Fig. 14 is an end elevational view of the tube stop ShOWn in Fig. 13.
Fig. 15 is a top plan view of the bottom cover.
Fig. 16 is a cross sectional view taken on the line 16-16 of Fig. 15.
Referring now to the drawings wherein like numerals refer to like and corresponding parts throughout the several views, the embodiment of the invention disclosed for illustrative purposes is incorporated in a housing or main part in section 2,780,390 Patented F eb. 5, 1957 body member 10 which is dished at its top 11 and has a tube slot 12 therein to receive the flattened end of a collapsible tube. The main body member 10 includes a bottom element 13 which is secured by cement or the like to the said main body member 10 as indicated by the numeral 14. The bottom element 13 has lever apertimes 15 and a tube slot 16 therein to accommodate respectively a pair of operating levers 17 and the lower flattened end of a collapsible tube 18 from which the contents have been dispensed as hereinafter described in detail. Inside and near the top of the main body member 10 adjacent the side walls 19 thereof are longitudinally disposed arcuate concaved lever sockets 20 into which the complementarily formed upper ends 21 of the operating levers 17 pivots. One side of the central portion of the main body member 10 below the dished top thereof is provided with a diagonally downwardly disposed tube stop 23 which extends slightly into one side of the said tube slot 16, the said tube stop 23 serving to prevent the tube 18 shown in dot and dash lines in Figs. 1 and 2 from accidentally sliding out of the dispenser during any dispensing cycle. The said tube stop 23 is suitably apertured at 230 to fit over the nubs formed on the sloping bottom of the top 11 of the main body member 10. The free end of each nub 100 is preferably upset by heat and pressure to secure the tube stop 23 firmly against the said sloping bottom 110 of the top 11 of the main body member 10.
The operating levers 17 are each provided with apertures 24 therethrough suitably formed to accommodate the cars 26 of a floating rocker cam 25, each rocker cam 25 having a curved cam surface 250 against which the inner face of an operating lever 17 is urged when the two operating levers 17 are manually squeezed together at their finger grips 1700. The inwardly disposed pivot portion 27 of each of the rocker cams 25 is rounded at 270 to engage an arcuate groove 29 formed in one of a pair of centrally disposed tube grip blocks 28. Each tube grip block 28 is constantly spring urged upwardly by a leaf spring 30, and each of the said leaf springs 30 are preferably anchored to the bottom of the grip block 28 thereabove as best shown in Figs. 1 and 2. The innermost surface of each tube grip block 28 is suitably deformed at 280 to engage the flattened end of the tube 18 in non-slip relationship as movement of the operating levers 17 toward each other actuate the rocker cams 25 which first urge the tube grip blocks into engagement with the tube 18 disposed therebetween and then carry the tube 18 downwardly as viewed in Figs. 1 and 2 to compress or squeeze the portion of the said tube 18 against the dished top 11 of the main body member 10, thus causing a certain quantity of contents of the tube 18 to be dispensed from the open end 1800 thereof.
It will be noted that the operating levers 17, the rocker cams 25 and the tube grip block-spring assemblies 25-30 are free floating in respect to each other, the ends of the leaf springs 30 being rather loosely retained in wells 31 provided in the side Walls of the main body member 10 just above the bottom element 13 thereof.
The amount of the contents to be dispensed from the tube 18 in any one squeeze of the operating levers 17 is predetermined by the extent of cam action to which any particular embodiment of the device is capable of exercising.
When the pressure applied to the operating levers 17 is released, the leaf springs 30 move the tube grip block 28 upwardly and outwardly, and, because of the shape of the curved cam surface 250 and the relationship to the operating levers 17, the said operating levers 17 are urged back to their original position shown in Fig. 1, which position is assumed by the operating levers 17 prior to the beginning of any dispensing cycle of operation of the dispenser. During the said upward and outward movement of the tube grip blocks and the resultant movement of the rocker cams 25 and the operating levers 17, the tube stop 23 holds the tube from accidental longitudinal movement with respect to the main body member ready for a subsequent dispensing cycle to be accomplished by again squeezing together the finger grips 1760 of the operating lever 17.
Although but one embodiment of the invention has been disclosed and described in detail, it is obvious that many changes may be made in the size, shape, arrangement and detail of the various elements of the invention without departing from the spirit and scope thereof as defined by the appended claims.
