3,515,493 HOLDER FOR STICK OF PASTY MATERIAL Ralph Gruska, Saint-Maui, France, assignor to Ejectoret S.A., Geneva, Switzerland, a company of Switzerland Filed Sept. 20, 1967, Ser. No. 669,025 Claims priority, application France, Sept. 22, 1966, 77,220; June 2, 1967, 108,851 Int. Cl. A43d 40/04 US. Cl. 401-74 7 Claims ABSTRACT OF THE DISCLOSURE A holder for a lipstick or the like is provided with two relatively rotatable tubular shells and a cup for bold ing the stick. Radial lugs on the cup extend through slots in the shells. The slots in one shell are axial and in the other are helical so that the cup moves axially on relative rotation of the shells. A cover encloses the shells. In order to reduce the likelihood of inadvertent relative rotation thereby pushing the stick onto the cover, mutually engaging friction surfaces are provided on the shells.
This invention relates to holders for housing sticks of pasty material such as rouges, pomades, cosmetics, pharmaceutical, veterinary or similar materials, of the type comprising two co-axial shells capable of relative rotation a cup for supporting the stick, which is movable in the inner sleeve and carries a lug extending through a slot in the inner sleeve and also engaging a slot in the outer sleeve, with one of the slots being longitudinal and the other helicoidal, and a removable cover for the entire assemblage.
In holders of the type specified it is desirable to prevent the outer sleeve turning, due to vibration, around the inner sleeve so that the cup approaches the cover whereby it is possible for the end of the stick to come into contact with the top of the cover thus deforming the stick.
To this end, according to the invention, at least one of the ends of one of the sleeves includes a resiliently deformable portion presenting a surface of revolution in permanent frictional contact with a complementary surface of revolution fast with the other sleeve.
In one embodiment for carrying out the invention the inner sleeve is provided with a knob and includes, by way of frictional surfaces which are partial surfaces of revolution, frictional and centering tongues defined by slots formed in the inner sleeve'adjacent to the end of the outer sleeve which is close to the knob, with the end of each of the tongues, in its free state, being at the end of a radius somewhat greater than the radius of the interior of the opposing surface of the outer sleeve.
The invention will be better understood from the following description and annexed drawings which show, by way of non-limitative examples, some practical forms of holders for sticks of pastry material in accordance with the invention.

FIG. 4 is a fragmentary view in longitudinal section of another form of assembled holder,
FIG. 5 is a view in elevation of the inner sleeve of the arrangement of FIG. 4 mounted in the outer sleeve with the outer sleeve being shown in section,
States Patent O1 Patented June 2, 1970 FIG. 6 is a side view of the arrangement in FIG. 5,
FIG. 7 is a view in cross-section taken along the line VIIVII of FIG. 6, the view looking in the direction of the arrows,
FIG. 8 is a fragmentary view in section of a modification of a detail of FIG. 3, and
FIG. 9 is a fragmentary view in section of another arrangement.
The holder for a stick of pasty material, such as rouge, pomade, cosmetics, pharmaceutical or veterinary or similar products shown in FIG. 1 comprises a cup 21 which carries a stick of pasty material 22. The cup is mounted for longitudinal sliding movement in an inner sleeve 23. To achieve this end, the cup 21 has projecting from its outer cylindrical surface two diametrically opposed lugs 25, which can slide in two longitudinal slots 27, 28, respectively formed in the cylindrical wall of the sleeve 23.
An outer sleeve 31 is capable of rotation around the inner sleeve 23 (see also FIG. 2) and is retained axially bytwo shoulders 32, 33 on the inner sleeve. In the inner surface of the cylindrical wall of the outer sleeve 31 are formed two diametrically opposed helicoidal slots 35, 36 which are engaged by the ends of the lugs 25 on the cup 21.
A metal reinforcing tube 39 is force fitted about the outer sleeve 31. End 41 of the tube is largely open as indicated at 42 for the passage of the stick 22. The entire assembly is enclosed by a cover of the usual type which, for clarity in the drawing, has not been shown.
In order, under the influence of vibration, to prevent relative rotation between the two sleeves when the holder is closed, and thus prevent the end of the stick 22 making contact with the bottom of the cover, the end of the outer sleeve 31, adjacent to a knob or manipulating member 43 formed on the inner sleeve 23 is provided with a reduced extension 44 (FIG. 2). The extension 44 possesses a certain flexibility is capable of bearing resiliently and frictionally against a corresponding cylindrical bearing surface 45 (FIG. 1) of the knob 43.
In order to increase the flexibility of the reduced end 44 (FIG. 2), slits 47 are formed in the end 44. The other end of the outer sleeve 31 has, as shown in FIG. 2, a reduced extension 44A provided with slots 47A. The extension 44A bears frictionally against a corresponding cylindrical bearing surface 48 of the inner sleeve 23 thereby contributing to the desired braking effect of the two sleeves one against the other.
In a modification shown in FIG. 3, a bearing surface 45A for the end of the outer sleeve 31 on the knob 43 integral with the inner sleeve 23 is frusto-conical instead of cylindrical.
The holder for a stick of pasty material shown in FIG. 4 comprises a cup 21 which carries a stick 22 and is mounted for longitudinal sliding movement in an inner sleeve 23. The cup 21 has projecting from its outer cylindrical surface two diametrically opposed lugs 25 capable of sliding movement in two longitudinal slots 27, 28, respectively formed in the cylindrical wall of the sleeve 23.
An outer sleeve 31 is capable of rotation about the inner sleeve 23 (see also FIG. 5) and is retained axially by two shoulders 32, 33 on the inner sleeve. In the inner surface of the cylindrical wall of the outer sleeve 31 are formed two diametrically opposed helicoidal slots 35, 36 which are engaged by the ends of the lugs 25 of the cup 21.
A metal reinforcing tube 39 is force fitted around the sleeve 31. One extremity of the tube has an end 41 which is largely open as indicated at 42 for the passage of the stick 22. A cover of the usual type (not shown) encloses the entire assembly.
In order, under the influence of vibration, to prevent relative rotation between the two sleeves when the holder is closed, and thus prevent the end of the stick 22 making contact with the bottom of the cover, the part of the inner sleeve 23 (FIGS. to 7) adjacent the end of each of the two slots 28 by a knob 43 integral with the inner sleeve, is formed into a resilient tongue. The tongue is defined by two longitudinal slots 51, 52, opening respectively into the two ends of a transverse slot 53 in the form of an arc of a circle. The slot 53 is formed in the part of the inner sleeve which is opposite to the corresponding end of the outer sleeve 31. The flexibility of each of tongues 55, 56 thus defined is a result of the inner sleeve 23 being made from a resiliently deformable material. The flexibility is increased by the presence of the end of the slot 28 in the tongue, and in particular its root which further weakens the section. Moreover, the component is made so that in its free state its outer diameter taken at the ends of the two tongues 55, 56 is a little greater than the diameter of the bore of the end of the outer sleeve 31 so that the ends of the tongues bear against the bore and produce a braking effect for relative rotary movement between the two sleeves. They ensure, in addition, the centring of the sleeves one in relation to the other.
The shape of the flexible tongues can be different from that illustrated. At least one of the slots can be inclined as indicated for example at 52A in FIG. 5.
In FIG. 8 is partially illustrated a modification of the arrangement of FIG. 3, and the same reference numerals are used to designate the same parts.
In the modification partially shown in FIG. 9 an enlarged upper part 23A of the inner sleeve 23 bears resiliently against a conical inner surface of a corresponding part 39A of the metal reinforcing tube 39 which is forcibly secured around the outer sleeve 31 and is fast therewith.
It is to be understood that the invention is not limited to the methods described and illustrated, which are given by way of example, and that numerous modifications can be made without departing from the scope of the invention.
