Patented May 10, 1938 ? 2,116,904 UNITED STATES PATENT OFFICE ? 2,116,904 DISPENSING DEVICE TUBES FOR COLLAPSIBLE , . Charles Stewart Mann, Vancouver, British (10; ? 1 lumbia, Canada ? ? ?Application September 13, 1937, Serial No. 163,567? ? ? 4 Claims. My invention relates to improvements in dis pensing devices for collapsible tubes. The ob jects of the invention are to provide means ca pable of attachment to collapsible tubes of shav 5 ing cream, tooth paste and the like, which can be opened by turning and closed by thumb pres sure applied to a button conveniently disposed on the side of the device; to provide means for non~rotatably securing the device to the nipple (01. 221-60) non-rotating sleeve 9 is aplunger 20 having its upper end shaped to conform to that of the ori ?ce to form a closure 2| therefor when said plunger is in raised position. The plunger 20 is provided with a transverse bore 22 in which ?a bolt 23 is slidably mounted. One end of the bore. 22 ?is provided with a screw plug 24 and a compression spring 25 is interposed between the plug and the bolt 23 to urge the lat 10 of the tube which is controlled by a thumb button and which is not normally removable and there fore cannot be misplaced. Further objects will appear as the speci?cation proceeds. ter radially outward into a vertical slot 26 in the 10 non-rotating sleeve 9 and a spiral slot 2'! in the rotating sleeve l6. The spiral slot 21 extends completely around the sleeve l6 and in conse The invention consists of a sleeve adapted for 15 attachment to the nipple of a collapsible tube quence one complete revolution of the cap is nec and a cap rotatable upon the tube which on be essary to retract the plunger to full open position. 15 Mounted in the side wall of the cap I8 is a ing turned one complete revolution opens the device to permit the extrusion of the paste from thumb button 28 having a spring retracted stem 29 which is aligned with the lower extremity of said tube, as will be more fully described in the following speci?cation and shown in the accom panying drawing, in which:Fig. 1 is a vertical sectional view of the inven tion. Fig. 2 is a plan view of the non-rotating slot ted sleeve, taken on the line 2-?2 of Figure 1. 25 Fig. 3 is a plan view of the rotating slotted sleeve taken on the line 3--3 of Figure 1. In the drawing like characters of reference� in 2O dicate corresponding parts in each ?gure. 30 The numeral I indicates a collapsible tube hav? ing shoulders 2 and a nipple 3 through which the contents of the tube are normally expressed. Fitted upon the nipple 3 is an internally thread ed sleeve 15 having a conical base ?ange 5 ex 35 tending to cover the shoulders 2 and having an internal ?ange 6 which is adapted to be drawn down onto a packing ring 1 carried upon the end of the nipple. The internally threaded sleeve is provided with 40 an annular rib 8, the purpose of which will here inafter appear. A non-rotating sleeve 9 hav? ing T-headed radial arms I0 is supported in re cesses ll formed in the upper face of the inter nally threaded sleeve 4 and is secured therein 45 in any suitable manner. The non-rotating sleeve 9 is ?tted at its base with a screw plug l3 having a stem I4 and forms an abutment for a spiral spring l5. _ Surrounding the non-rotating sleeve 9 is a ro 50 tating sleeve [6 having at its base T-headed ra dial arms ll by which it is secured to the inner wall of a cap generally indicated by the numeral l8. The cap l8, rotatable upon the internally threaded sleeve, is provided at its apex with a 55 discharge ori?ce l9. Slidably mounted in the the spiral slot 21 and is adapted on being pressed to thrust the bolt 23 out of the spiral slot that the 20 plunger may be raised to closing position and the bolt may re-enter the spiral slot at its upper ex tremity. The cap I8 is held against endwise movement along the internally threaded sleeve 4 by an an- 25 nular groove 30 which engages the annular rib 8. The internally threaded sleeve 4 is held against rotational movement upon the nipple 3 by a pointed set screw 3| having a transverse ridge 32 which is adapted to be engaged by a 30 transversely slotted inner enlargement 33 of a stem 34. The stem 34 passes through a bushing 35 screwed into the wall of the cap l8, which bushing has a concentric recess 36 in which a button 31 secured upon the outer end of the stem 35 34 is slidably movable. The stem 34 is held in its outermost position, as shown in Figure 1, by a spring 38 which extends between the base of the recess 36 and the inner face of the button 31, in which position the enlargement 33 is housed within the thickness of the Wall of the cap and may therefore turn freely. The device with its parts as shown is with the ori?ce l9 open as when dispensing paste from the tube. When it is desired to close the ori?ce pressure is applied to the thumb button 28, which dis places the bolt 23 from the spiral slot 21 leaving it only in the vertical slot 26 of the non-rotating sleeve 9; the spring l5 then urges the plunger upwards to close the ori?ce and the bolt 23 on reaching the upper extremity of the vertical slot projects again into the spiral slot but does so at the upper extremity of said spiral slot. When it is desired to again open the ori?ce it su?ices to turn the cap l8 and through it the rotating sleeve 40 45 50 55 2 2,116,904 16, which causes the spiral slot thereon to urge the bolt 23 downwardly throughout the length of the vertical slot of the non-rotating sleeve, thus lowering the plunger to the open position illus trated. It will be obvious that the extrusion of paste will be automatically shut o?, the ori?ce closed and hermetically sealed in response to the appli cation of pressure to the thumb button. What I claim as my invention is: 10 1. In a dispensing device for collapsible tubes having a threaded sleeve, a cap rotatable about the sleeve having a discharge ori?ce, a sleeve ro tatable with the cap, said rotatable sleeve having 15 a spiral slot extending entirely therearound, a plunger endwise movable within the rotatable sleeve, a spring pressed bolt transversely slidable in the plunger adapted to engage the spiral slot, means preventing rotation of the plunger, means 20 carried by the cap for displacing the bolt from the spiral slot, and spring means for urging the plunger to close the ori?ce. 2. In a dispensing device for collapsible tubes as claimed in claim 1, said bolt being urged into slot engaging position by a coil spring carried within the plunger and said spring being enclosed within the plunger by a screw plug. 3. A dispensing device for collapsible tubes comprising a threaded sleeve, a cap rotatable about the sleeve, said cap having a discharge ori?ce, a non-rotating sleeve carried by the threaded sleeve and a rotating sleeve connected to the cap surrounding the non-rotating sleeve, CR said non-rotating sleeve having a vertical slot and said rotating sleeve having a spiral slot, at plunger slidable within the non-rotating sleeve adapted when in one position to close the ori ?ce, means extending from the plunger into the 10 vertical slot and the spiral slot, means for urg ing the plunger into ori?ce closing position, and a button carried by the cap for releasing the slot engaging means from the spiral slot to permit the plunger to move and close the ori?ce. 4. In a dispensing device having a sleeve adapted for attachment to the nipple of a col lapsible tube and a cap rotatable upon the sleeve, said sleeve having a threaded opening in its wall and a set screw in said opening adapted to en gage the nipple of the tube, a bushing in the cap adapted to be brought into register with the threaded opening in the sleeve, a spring retract ed stem carried by the bushing, said stem being provided with means at its inner end for en-V gaging the set screw to turn it when moved against its retracting spring.
