STICK-DISPENSING DEVICE FOR SOAP AND THE LIKE.

Application filed March 30, 1925.

T0 (1. whom it may concern:

Be it known that I, J ACQUES Roonecomes, a citizen of the Republic of France,

residing at Paris, France, have invented certain new and useful Improvements in Stick-Dispensing Devices for Soap and the like, of which the following is a specification.

Stick-dispensing cases are known which are constituted by a cylinder through which stick (soap, cosmetic, rouge, etc.) can be fed by introducing a rigid follower into the bottom of the cylinder in order to push upwards the holder carrying the stick. A spring plate, most generally star shaped. is secured to the bottom face of the holder. its purpose being to keep the holder in position at any height by means of the pressure of the ends of its arms against the cylinder wall; as the holder is fed upwards the arms become inwardly curved, and since the cur vature is directed towards the bottom of the cylinder the spring arms do not allow the holder to move back, such stoppage being necessary to permit the stick of soap, cosmetic, etc., to be used. If the inside surface of the case is absolutely cylindrical the holdor can be ultimately pushed out through the top and the stick replaced by another one fixed in a holder and introduced through the bottom of the case. hen, however, the stick becomes swollen during use, say due to moisture, it can no longer be pushed upwards, owing to suppression of all play between its cylindrical outer surface and the inner surface of the wall of the case.

Attempts havebeen made to do away with this drawback by providing an appreciable space between the surfaces of the stick and case wall; but then the said stick is liable to wabhle in the case, and in order to prevent that, two ways of guiding the stick have been proposed:

1. By means of a holder having an outside diameter nearly equal to the inside diameter of the case, while adapted to slide therewithin .7

2. By decreasing the diameter of the up per part of the case for a very short distance.

The surfaces of the stick and of the case in frictional contact are then so small that a swelling of the stick will not prevent the stick from being pushed outward, Wl'llCl'l ilQ- h in eas ble if h whi e latera Sun Serial No. 19.386.

face of the stick had to rub with cxaggeratml pressure against a very large portion of thc inner surface of the case.

The above described device. however. while adapted for ensuring guidance of a stick swollen during use, does not permit the holder to be forced out through the top of the cylindrical case, since the diameter of the said top is slightly less than the diameter of the holder. On the other hand. the curved arms of the holder prevent, as previously explained, its being moved back.

The object of my invention is to provide a device that will permit the holder to be broughtback to its starting point after a full travel and. then to be extracted from the case, the obvious and desirable result being that users will be enabled, when the con tents of the case are used up, to remove the holder and to introduce into the case a new holder, furnished with a full-sized fresh stick.

In order to make my invention more clearly understood I have illustrated, as an 'cnample, an embodiment thereof in and by the drawing appended hereto and wherein:

Figure 1 shows in longitudinal section a push-case with the holder at the end of its travel.

Figure 2 is a section of the holder showing the position of the spring arms while the push-case is in use.

Figure 3 is a section of the holder showing the position of the spring arms while the worn stick is being removed from the push case.

Figure 4 is a plan View of the under part of the holder.

In all the figures the same reference letters denote the same parts.

On a transverse plane a- (Figure l) and at a suitable distance from the top or mouth of the cylinder (1 is provided a circular recess 6; when the spring arms 0 of the follower of the holder (Z reach the said recess, they are no longer flexed, since their terminals automatically snap into the rccess. Under the effect of a downward pressure on the stick the spring arms are again flexed, their curvature this time being directed upward,- as shown by Figure the profile of the holder permitting this rcversing of the direction of curvature of the spring arms.

Owing to this fact return of the holder towards the opening through which it was introduced is possible and it can be taken out and replaced by a similar holder carrying a new stick.

end of the case or that could be secured by any other suitable means at the end of the case.

I claim as my invention:

1. A stick-dispensing device, comprising a tubular case having an open end and formed adjacent such. end with a circumferential recess which is disposed transverse to the axis of the case; a stick holder slidable axially within said case toward and from its open end; and a follower secured to the bottom of the holder and provided with a plurality of spring arms, the terminals of which frictionally engage the inner surface of the wall of the case and are normally flexed in one direction consequent upon such engagement to maintain the holder in place and prevent it from moving backward, but which are adapted to snap into said recess on reaching the same;

the recess and spring arms being so constructed that when the terminals of said arms are received in said recess, the said arms may be flexed in the reverse direction to enable the backward movement of the holder.

2. A stick-dispensing device, comprising an open ended tubular case; a stick holder slidable axially in either direction in the case and serving to eject the stick through the forward end thereof during its movement toward such end, said holder adapted to be inserted and withdrawn solely through the rear end of the case; and a follower having spring arms secured to the bottom of the holder and frictionally engaged with the inner surface of the wall of the case during the forward movement of said holder to maintain the holder in place and prevent it from moving backward; means being provided to automatically release said arms from such frictional engagement and permit their reverse flexure, when the holder reaches a predetermined point in its forward movement, to enable its subsequent backward movement and withdrawal.

In tesitmony whereof I aflix my signature.

JACQUES ROCHEROLLES.
