This invention relates to the art of dispensers and particularly to a structure for dispensing paste Vor cream-like substances from collapsible containers such as shaving soaps, tooth paste, library past/e, and the lih y lt is a primary object of my invention to provide means for positively ejecting a lixed amount of the material to be dispensed (herel@ inat'ter designated as soap as one particular medium) at each of a series of succeeding like operations from a collapsible unit until the unit is emptied.

An important object is to provide a dispensing structure adapted to receive a collapsible filler unit and adapted to be opel'- ated to-press the contents from the unit in successive operations and to close the unit from the air between operations.

An important object resides in the means for initially shearing oil' the closed discharg ing end of the 'collapsible unit.

Still further objects reside in the means for engaging the collapsible unit and compressing thewalls together; in the means for operating the compressing means from a lateral travel of a member pushed from without; and in providing for a uniform discharge from the unit at various proportions of collapse of the unit.

These and other objects will become apparent in the following description of my invention, with reference being made to the accompanying drawings, in which Fig. 1 is a fragmentary front elevation of a dispenser embodying my invention;

1 and 2.

Like characters ot reference indicate like parts throughout the several views in the drawings.

Referring iirst to Figs. 1-4 in the drawings, l form a box 15 open from the front with a supporting bracket 16 at the rear. Along the inner right hand side, I mount a bar 14' to be pivotally supported by the side @if by the top and bottom links 18 and 19 respect-ively so that the bar normally tends to drop longitudinally toward the box bottom with a bodily movement toward the rear. A cover 2() is hinged at the top or' the bon 15 79 to swing down over the front of the box and have its sides and lower end 21 telescope over the box and an arm 22 extends forwardly from the bar 17 to be contacted by the inner side of the cover. This arm 22 may be moved 7@ along the bar 17 to be secured thereto at any oint by the set screw 78 through the flanffe $9. The barv 17 is normally held upwardly and outwardly by a spring, here shown as the tension spring 23, which spring not onl 30 swings the bar 17 outwardly from the ba of the box 15, but also, through the arm 22, swings the cover 20 outwardly.

1n the lower end of the box 15 is provided a boss 24 having a tapered hole vertically ex- 85 tending therethrough and the under side of the box end is arcuate with its center of curvature at the hinge of the box cover. The lid end is also arcuate to slide over the under side of the box end with a close sliding t and 99 has a rearwardly projecting plate 25 with a shearing edge at its rear side. An elongated hole 26 yis provided in the plate 25 at the proper location whereby when the lid is in its normal outward position, the plate covers over the discharge end of the hole in the boss 24 with the elongated hole 26 forwardly thereof.

A collapsible container 27, here shown as the well known tube commonly employed to contain shaving cream, has a conical nipple 28 which is fitted into the hole through the boss 24 and is of sufficient length to project on through below the box end as indicated by the dash lines, Fig. 2, the nipple being hollow but closed over its end. An annular shoulder 29 is provided about the nipple above the boss over which shoulder a latch bar 30 pivoted on the boss 24 is swung to prevent withdrawal of the nipple from the hole in the boss. In this position the container extends -vertically upward within the box 15 in an inverted position. The lid or cover 2() is swung away from the opening in the box during the positioning of the container in the box as above described.

I provide a carriage 31 to have its back adapted to'slide vertically over the inner side of the back wall of the box 15 and under the guide strip 80. Side plates 32 and 33 extend forwardly from the back and rotatably support a shaft 34 which is provided with a longitudinal slot 35 therethrough, Fig. 10, to receive the upper Hattened end ofthe container whereby, by revolving the shaft 34, the container may be wound around the shaft to compress the container walls together to form a flat ribbon of double thickness. On the outer face of the plate 33 vis an larm 36 pivoted by its lower end to the plate, having the shaft 34 extending through a slot 37 there` in, and extending above the shaft to carry a pawl`38 on its outer side. A ratchet wheel 39 is fixed on the outer end of the shaft 34 to have the arm 36 between it and the plate 33. A leg 40 extends rearwardly from the arm 36 and has an outwardly turned finger 41 positioned to pass transversely across the back edge of the bar 17 whereby rearward travel of the bar 17 will push on the nger 41 to cause the pawl 38 to engage the teeth of the wheel 39 and thereby revolve the shaft 34. To limit the rotation of the wheel, an adj ustable stop 42 is carried on the plate 33 to contact the under side of the pawl 38 to hold it away from engagement with teeth of the Wheel as may be desired, lowering the stop causing the pawl to engage the wheel more quickly than when raised.

I The container 27 having been positioned in the box and the shaft 34 engaged over the upper end of the container,.the cover 2O is swung around to close 'the box 15 and the shearing edge of the plate 25 comes into contact with the end ofthe nipple 28 projecting through the bottom of the box. The cover is pushed back to cause the nipple end to be sheared off' and to cause a spring finger 43 to slide up over a stop 44 on the box end and drop down therebehind with its downturned end to preventbutward travel of the cover. By pushing the cover on in further over the box, the arm 22 is pushed to move the bar 17 rearwardly which carries the arm 36 rearwardly to have the pawl 38 revolve the wheel `revolving means.

39 and thus wind `the container 27 around the shaft 34 a short distance whereupon the pressure thus exerted on the contents of the container causes the contents to flow out the opened end of the nipple 28, the plate 25 having moved in to have the hole 26 register over the nipple end. Release of the cover permits the spring 23 to return the parts to their normal position ready for a subsequent operation, the nipple end being then closed over by the plate 25 to exclude air therefrom and to prevent further exudation of the contents.

As the container 27 is wrapped around the shaft 34 in a collapsed condition, uniform rotation of the shaft 34 at each operation of the cover 20 would .cause an increasing amount of discharge therefrom due to the increasing diameter of thecollapsed tube on the shaft. To compensate for this condition, I slope the rear edge of the bar 17 to have its lower end closer to the back of the box 15 than is its top so that as the carriage 31 drops downwardly with the emptying of the container, the arm 36 is not permitted to return as far forwardly as at the upper positions and hence the pawl 38 can not engage the ratchet wheel to move it as far. When the container'27 is emptied, a rod 45, shown in dash lines, Fig. 2, may be inserted through a hole 46 in the bottom of the box 15 to raise the spring 43 above the stop 44 and thereby permit the cover to be pulled out from over the box and opened around to permit the latch bar 30 to be moved from over the shoulder 29 so that the container 27 may be lifted up to withdraw the nipple from the boss. By pulling on thev lower end of the container it may be readily unwound from the shaft 34, disengaged therefrom, and a new filled container substituted therefor.

Asa precaution to prevent damage to the mechanism by further operation of the cover when the container is empty, l provide a stop post 47 on the side of the box 15 to project into the path of the outer end of the pawl 38 at the proper elevation to contact the pawl and hold it up out of engagement with the. wheel 39 when the container is emptied thereby preventing further rotation of the shaft 34.

In Fig. 11, is shown a slightlv modified Here the carriage 31 is reversed and the wheel 39 is on the'let hand side with an arm 48 pivoted on the shaft 34 to have an extension 49 over to the operating bar 17 to receive rocking motion therefrom as before. The lower end of the arm 48 extends below the wheel 39 to carry a pawl 50 thereon having a weighted outer arm to cause the pawl to swing upwardly against' the wheel. A spring 51 insures contact of the pawl with the wheel, and a spring 52 engaging this lower end of the arm 48 normally rocks the arm to maintain the extension finger 53 against the bar 17. Therefore,

Lacanau when the bar 17 is moved rearwardly, the fin er 53 is carried back to rock the arm 48 an cause the pawl to revolve the wheel 39. A dog 54 pivoted on the plate 33 drops cover 56 is used. A carriage 57 is slidably carried in the box and rotatabl supports the shaft 58 comparable to the sha t 34. A shaft 59 is rotatably carried in the box and has a bevel gear 60 carried thereon in driving relation by engaging inthe keyway 61 and is slidable therealong. The gear v60 is in constant mesh with the gear 62 lixed on the shaft 58. A plunger 63 extends through the cover 56 and is normally extended by a spring 64 to have the stop 65 on the plunger contact the inner side of the cover as a limiting element. On the side of the plunger 63 are formed teeth in the nature of a rack bar which are inconstant mesh with a ring gear 66 rotatably supported around the star member 67 which is fixed on the vertical shaft 59. The star member 67 is provided with a plurality of right angled notches 68, here shown as four in number, one side of the notch being on a radius with the other side at right angles thereto. In each notch, is positioned a ball bearing 69 having a diameter slightly less than the length of the radial side of the notch and a spring 70 urges each ball'out- Wardl into the acute angle formed between the ot er side of the notch and the inner face of the ring gear 66. Now as shown in Fig. 8, pushing in on the plunger 63 will revolve the gear 66, and since the balls 69 are in contact therewith, they will be wedged between the gear and the sides of the notches of the star member 67 and thereby revolve the mem- 1 ber 67 and the shaft 59 to, in turn, revolve the shaft 58 upon which the collapsible unit is wound. In this modified form, the under side of the vbox 55 is provided with a widened T-slot in which a valve plate 71 slides to close off the nipple end of the container 27. A notch is provided through the box above the plate and a neck 72 connects the plate with the plunger 63 whereby the plunger moves the plate upon actuating the shaft 58.

Referring to Figs. 5 and 6, it is ossible to actuate the bar 17 by a plunger rod 73 in place of a hinged cover as shown in Fig. 1 4. `The rod 73 is slidingly carried through the stationary cover 56 with a connection 75 to the valve plate 76 on the under side of. the box and is carried rearwardly to Contact the bar 17 so that by pushing in on the rod 73, the bar 17 is moved rearwardly as above described. The plate 76 is moved across the container nipple opening to open and close it and carries a shearing edge on its backside for the initial shearing oli of the nipple end.
