The pencil is removed and when the composition hardens in the casing, the pencil may be sharpened. <IMAGE>

Description

SPECIFICATION Make-up pencil extruder The instant invention relates to cosmetic make-up pencils and the like and more particularly to an extruder for making such pencils.

For many years children, particularly girls, have found amusement in wearing make-up.

In this regard, cosmetic manufacturers have produced a number of varieties of water soluble lipsticks, rouges, mascaras and make-up pencils for use by such children. The instant invention relates to a novel apparatus whereby children can make their own make-up pencils for their personal use. The device herein disclosed is therefore directed towards the fulfillment of the need for children's make-up pen cils and also provides an effective and amusing device which is both interesting and educational to operate.

Previously known devices representing the closest prior art of which the applicant is aware are illustrated in the following U. S.

patents: BURNS et al, No. 3,590,749; METH et al, No. 3,685,936; METH et al, No.

3,892,510; and KRUCKEL et al, No.

4,230,655. The patents to BURNS et al and METH et al relate to extrusion devices for forcing a moldable material into a mold or die of a desired configuration but include relatively complex lever operated plunger mechanisms for effecting such extrusion. The device of the instant invention differs substantially from these previously known devices incorporating means for heating a particulate material prior to extrusion and having a normally operable screw type extrusion mechanism. The patent to KRUCKEL et al relates to a method of casting a cosmetic pencil having a pointed end and does not teach structure which can be used to extrude cosmetic pencils. It is therefore felt that the instant invention represents the first attempt to provide a simple and amusing device for use by children to extrude cosmetic pencils and the like.

The instant invention provides a novel device of relatively simple construction for extruding cosmetic make-up pencils and the like. The device can be easily operated by young children and provides amusement both in its operation and in the use of the make-up pencils thereby manufactured.

The device includes a piston-cylinder arrangement for extruding a melted make-up composition from the cylinder into a pencil casing. An orifice on the inner end of the piston provides communication between the cylinder and a longitudinal passage in the piston so that as the piston is advanced into the cylinder, the melted composition is forced through the orifice and into the passage.

Accordingly, when a pencil casing is positioned within the passage adjacent to the orifice, the melted composition is forced into the axial bore of the casing filling the same.

The extruded pencil may then be removed from the passage within the piston and after hardening a point may be formed on the pencil with conventional sharpening means.

The piston and cylinder assembly is mounted within a covered container suitable for containing a heated liquid so that the liquid may be used to heat the cylinder and the composition contained therein to melt the same prior to extrusion. In this connection, a thermostatic cap is provided on the container which cap visibly expands at a temperature approximately equal to the melting point of the composition. A user of the device can therefore visually determine whether the temperature of the heated liquid to be used in the container is sufficient to melt the composition simply by exposing the cap to the liquid prior to filling the container.

In order to advance the piston into the cylinder, the piston is attached to a threaded plug which is advanceable in threaded engagement in a threaded sleeve mounted in a cover on the container. The device is, therefore, operated simply by twisting the plug in the sleeve causing the piston to be advanced into the cylinder thereby forcing the melted composition into the pencil casing.

Accordingly, it is an object of the instant invention to provide a device for extruding melted make-up pencil composition into pencil casings.

Another object of the instant invention is to provide a device which a child can use to make her own cosmetic make-up pencils and the like.

Other objects, features and advantages of the invention shall become apparent as the description thereof proceeds when considered in connection with the accompanying illustrative drawings.

In the drawing which illustrates the best mode presently contemplated for carrying out the present invention.

Figure 1 is a perspective view of a make-up pencil extruding device embodying the instant invention; Figure 2 is an exploded side sectional view thereof; Figure 3 is a side sectional view taken along line 3-3 in Fig. 1; Figure 4 is a fragmentary sectional view taken along line 4-4 of Fig. 1; and Figure 5 is a perspective view illustrating the method of forming a pointed tip on the make-up pencils made with the device of the instant invention.

Referring now to the drawing, the device of the instant invention is generally illustrated in Figs. 1 through 3 at 10. The device 10, as will be seen, includes a circular container 1 2 having a circular cover 1 4 in which an extru der assembly generally indicated at 1 6 is mounted.

The container 1 2 and cover 14 which are preferably molded from a suitable plastic material are illustrated most clearly in Figs. 2 and 3. The container 1 2 is a conventional open dish-type container and the cover 14 is dimensioned to fit snugly thereon with downwardly projecting circular flanges 1 6 and 1 7 sealingly engaging the upper portion of the side walls of the container 1 2. An outer skirt 20 on the cover 1 4 extends downwardly in outwardly spaced relation to the side walls of the container 1 2 and a filler hole 22 having a cap 24 is provided in the cover 14.

A circular ring or boss 26 extends coaxially upwardly from the top of the cover 14 and a tubular sleeve 28 extends downwardly therefrom into the interior of the container 1 2. A single thread or spiral ring 30 is provided on the interior of the sleeve 28 and circular main cylinder support ring 32 haing inner and outer upwardly extending flanges 34 and 36 is attached to the bottom end of the sleeve 26 with the flange 36 abutting the outer surface of the sleeve 28 as at 38. A cup 40 having an upper peripheral flange 42 defines a main cylinder 44 of substantially circular cross section within the container 12. The cup 40 is secured to the flange 34 since the flange 42 rests on the upper edge thereof and is secured in position by cylinder retaining ring 46 which is positioned on the flange 42 and is secured to the flange 34 as at 48.

In use a cosmetic pencil composition comprising waxey solid particles 50 meltable by heat to a viscous fluid consistency is placed in the cylinder 44 for extrusion into a pencil casing or the like. For this purpose a piston 52 is provided comprising a tubular member 53 and a piston head 54 which is of substantially the same cross sectional configuration and dimension as the cylinder 44 so that the piston head may be snugly received therein.

The bottom end of the head 54 defines an orifice plate 56 having an orifice 58 therethrough providing communication with a tapered circular passage or bore 60 in the tubular member 53 through a hub 62. As the piston 54 is advanced into the cylinder 44, the viscous composition 50 is forced through the orifice 58 and into the bore 60. When a tubular pencil casing 64 having an open bore 66 therein is positioned in the bore 60 with the hub 62 extending into the bore 66 so that the upper side of the plate 56 acts as a seat for the end of the casing 64, the hub 62 provides sealed communication between the orifice 58 and the bore 66. Accordingly, when the piston 52 is advanced into the cylinder 44, the composition 50 is forced or extruded upwardly into the bore 66.

A plug 68 having threads 69 is provided to advance the piston 52 into the cylinder 44 and to maintain proper alignment thereof during such advancement. The piston 52 is integrally attached to the plug 68 and the tubular member 53 extends longitudinally therethrough. The plug 68, as will be seen, is receivable in the sleeve 28 with the threads 69 thereof engaging the thread 30 as at 70 to advance the piston 52 into the cylinder 44 as the plug 68 is advanced in the sleeve 28.

Wing members 71 are provided on the top of the plug 68 to facilitate such advancement.

To assure that the cup 40 is not damaged by excessive or improper advancement of the piston 52 in the cylinder 44, a stop post 72 is provided extending upwardly from the bottom of the container 1 2 to provide support means for the cup 40.

As will be seen from Figs. 1 to 4, a circular recess 74 is also provided in the cover 14 and a thermostatic cap 76 having a downwardly extending pin 78 which extends through the cover 14 is mounted in said recess 74. A thermostatic bimetallic coil 80 is attached to the pin 78 on the under side of the cover 14 and is also secured to a pin 82 which extends downwardly from said cover 14. Upon exposure to a predetermined temperature which is approximately equal to the melting point of the composition 50, the coil expands flexing upwardly and moving the cap 76 upwardly within the recess 74. Accordingly, by exposing the cap 76 to the liquid to be used in the container 1 2 to melt the composition 50, the cap 76 can be used to visually apprise an operator of the device 10 as to whether the temperature of such liquid is satisfactory for use.Specifically, tap water may be run over the cap 76 and adjusted as to temperature until the thermostat actuates, thereby signifying that the proper water temperature has been reached.

The instant invention therefore provides an effective device for extruding make-up pencils and the like and one which is simple to operate and may be used by children of various ages. In operation the cap 76 is first exposed to a heated liquid 84 (preferably tap water) to determine if the temperature of such liquid is satisfactory to melt the composition 50. If the cap 76 moves upwardly, the container may then be filled with the liquid 84. A premeasured amount of make-up pencil composition 50 is then positioned in the cylinder 44 and the composition 50 is melted by the liquid 84. A pencil casing 64 is then inserted into the bore 60 with the end of said casing 64 receiving the hub 62, and the plug 68 is then threaded into the sleeve 28. As the plug 69 is advanced in said sleeve 28, the piston head 54 advances into the cylinder 44 forcing the melted composition 50 through the orifice 58 and upwardly into the bore 66 in the casing 64. After the composition 50 enters the bore 66 and the casing 64 is removed from the device 10, which removal is facilitated by the outward taper of tubular member 53, the composition quickly cools since it is no longer exposed to the heated liquid 84 and it therefore solidifies in the casing 64 (within 3 to 5 minutes) forming the make-up pencil 86. A pencil sharpener 88 may then be used to form a point on the pencil 86 which is preferably slightly blunt for safety reasons.

The device 10 therefore provides a novel and amusing device which is effective for extruding make-up pencils and the like. It is safe and simple to operate and may therefore be used by children of various ages. Different color make-up pencils may be made simply by using different colored compositions 50.

While there is shown and described herein certain specific structure embodying this invention, it will be manifest to those skilled in the art that various modifications and rearrangements of the parts may be made without departing from the spirit and scope of the underlying inventive concept and that the same is not limited to the particular forms herein shown and described except insofar as indicated by the scope of the appended
