AGENT CARRYING CASE AND DISPENSER FOR ELECTRICALLY HEATED HAIR CURLERS This invention concerns electrically heated hair curlers, in particular a combination carrying case and dispensing unit for storing, electrically heating, and dispensing hair curlers which can be used separately or in conjunction with the hair curlers and temperature indicator described respectively in the copending US. Patent application Ser. No. 883,4 1 8 filed Dec. 9, 1969 and Ser. No. 872,242 filed Oct. 29, 1969.

There are a number of devices commercially available for the storage and dispensing of electrically heated hair curlers; however, none of these devices provide the advantages and added conveniences of the present invention. The carrying case and dispenser of this invention was developed to meet the demand for a safe, reliable, and quickly heatable unit which also provides a temperature indicator to inform the user when the hair curlers are ready for use. Furthennore, the case has a gravity feed arrangement for dispensing the hair curlers, protective conductive heating rails which will eliminate accidental electrical contact and injury to the user, and a lighted makeup mirror for the convenience of the user.

The carrying case has a tray portion having a bottom, four upstanding sidewalls, and a cover. The interior of the tray is divided by longitudinal partition walls into three or more separate portions, each having a width corresponding to the length of the individual hair curlers such that a plurality of assorted hair curlers can be accommodated in a stacked and uniform arrangement. These curlers may be of the type as described in the copending application Ser. No. 883,418 previously referred to and each hair curler may be of a different size i.e. diametric dimension, so that the user is provided with an assortment of difierent sized curlers. The longitudinal partition walls are arranged parallel to each other and to two of the sidewalls of the tray and the confronting faces of these partitions and sidewalls have a track or groove defined therein which accommodates the protruding terminal projections extending from both ends of the hair curlers. An electrically conductive rail member is positioned in this track member such that a current can simultaneously be passed through all of the hair curlers contained within the tray to heat same. This current is also passed through the temperature indicator described more fully hereinafter, the temperature indicator will indicate to the user when the hair curlers are sufficiently heated and ready for use. Such a temperature indicator consists basically of an enclosed housing containing a temperature sensitive wax which is in a solid state and opaque at room temperature. A heat source is placed in close contact with the wax so that when sufficient heat is generated the wax will change to a liquid state and become transparent. The signaling means such as a painted surface which may be fluorescent or phosphorescent, a neon lamp, molded colored plastic, raised lettering or any other contrasting-type mark is placed below the wax material. This signaling means will not be clearly visible at room temperature and will only be clearly visible when the wax has been sufficiently heated and melted by the heat source, for example, an electrical resistor. When the cover is pivoted behind the bottom of the tray, it will support the tray in a substantially upright position and the curlers contained therein will by gravitational force be urged toward the lower portion of the tray. The hair curlers can be individually removed from the dispenser without danger of electrical shock to the user or accidental injury through immediate contact with the electrical rail or heating element. Furthermore, a mirror and mirror backing placed over the open side of the dispensing tray will serve to hold the hair curlers in the tray while in the upright position. This will also provide added convenience to the user. After usage, the curlers are replaced in the dispensing tray and the cover member is pivoted around and over the open side of the tray to lockingly engage the tray and provide a handy and useful carrying and storage case for the hair curlers.

It is an object of this invention to provide a compact and convenient combination carrying case and dispenser for electrically heated hair curlers.

It is another object of this invention to provide a dispenser for electrically heated hair curlers in which a plurality of hair curlers, of assorted sizes, are simultaneously and uniformly heated to a proper operating temperature and wherein indicating means inform the user when this temperature has been reached.

It is the further object of this invention to provide a dispenser for electrically heated hair curlers having a self contained supporting member for holding the dispenser in an upright position to provide for the individual dispensing of hair curlers by gravitational feeding of same to an opening in the dispenser.

The above and other objects, features and advantages of the present invention will be apparent from the following description of the preferred embodiments when considered in connection with the accompanying drawings wherein;

FIG. 1 shows a front elevation view of the dispenser tray with the hair curlers therein.

FIG. 2 is a sectional view along lines 2-2 of FIG. 1.

FIG. 3 is a side elevational view of the dispenser shown in the upright position.

FIG. 4 is a perspective view of a temperature indicator which may be used in the present invention wherein a fluorescent paint is used as the signaling means,

FIG. 5 is a sectional view of the temperature sensor of FIG. 4 in its mounted position,

FIG. 6 is a perspective view of another type of temperature indicator used in the present invention wherein a neon lamp is used as the signaling means, and

FIG. 7 is a cross-sectional view of the indicator shown in FIG. 6.

The carrying case and dispenser as shown in FIGS. 1 and 3 consists of a dispensing tray 1, and a cover member 2 pivotally attached to the dispensing tray. The cover member shown in FIG. 3 is in the open position and is also adapted to occupy a closed position wherein the cover member is disposed over the open face 3 of the dispensing tray and lockingly engages the tray so as to secure the hair curlers therein and to provide a convenient means of transporting or storing same. The dispensing tray consists of bottom surface 4 and four

upstanding sidewalls

5, 6, 7 and 8, and may be mounted within a casing 9. The interior of the tray is partitioned by parallel walls to divide same into a plurality of separate compartments for accommodating the hair curlers 10, in this embodiment two parallel walls 11 and 12 on a position parallel to the upstanding side walls 5 and 7, it should be understood that any number of parallel walls can be used. A mirror 13 with an appropriate backing, is placed over these partitioned walls and separate compartments so as to enclose the hair curlers therein and to provide for the convenience of the user. Additionally, an illuminating lamp 14 may be attached to the dispensing tray, in this embodiment it is attached to the upstanding side wall 6 and serves to illuminate the working area and mirror for the user.

The partition walls 11 and I2 and parallel side walls 7 and 5 are spaced so as to accommodate a plurality of hair curlers therebetween and also for providing an electrically conductive circuit for passing a current through the curlers for the heating of same. This is accomplished by the positioning of conductive rails 15 as shown in FIG. 2 within the partition and side walls. A gap 16 is provided in these walls for permitting the insertion of the terminal end portion 17 of the curlers 10 so that electrically conductive contact can be made between the curlers and the conductive rails 15. As shown herein the partition walls may be hollow and the conductive rails shaped for complementary press-fit inside the hollow partition walls.

This method of positioning the curlers between the partition walls also serves to hold the curlers in a stacked formation when the dispensing tray is in its upright position. The recessed mounting of the electrically conductive rail prevents the possibility of accidental contact therewith by the user and also prevents any contact with the terminal end projections 17 which may be at an elevated temperature. The gap 16 extending longitudinally along the length of the side walls and partition walls form a conductive track for guiding the hair curlers to the openings 18 at one end of the dispensing tray when the tray is in the upright position and the curlers are gravita tionally fed toward these openings. The notches or slots 19 contain in the upper and lower portions of the partition walls and sidewalls communicate with the conductive track and guide rail and will accommodate the terminal end portions of the hair curlers. These notches or slots 19 effectively provide for the terminal projections 17 a respective entrance to and exit from the conductive track.

In order to prevent the inadvertant exit of hair curlers from the notches located at the lower end of the dispensing tray, particularly when the tray is in the upright and gravitational feeding position, the notches are provided above the lowest end of the track so that the hair curler must manually be moved upwards to align the terminal end portions 17 with the notches l9 and the hair curler can then be withdrawn from the track.

The dispensing tray and cover can be made of a high-impact styrene. Similarly, the casing placed around and surrounding dispensing tray, can also be made of a high-impact styrene. The casing can also be provided with a special compartment such as shown at 20 for storage of the power cord 21. Additionally, an on-ofi switch shown at 22 for activating the con ductive track and a temperature indicator shown at 23, examples of which are more fully described hereinafter may be mounted on the casing.

One type of temperature indicator which may be used in this invention is shown in FIGS. 4 and 5, is referred to generally at 23 and consists of a housing which can be formed from a plastic material and comprises a base member 24, having a ledge portion 25, for snugly supporting and accommodating the upper housing 26; thus forming a leakproof container for holding waxlike material 27 within the upper housing. A contrasting color paint which is easily discernible is applied upon the upper surface 28 of the base member, in this instance a fluorescent paint is used, however, it should be noted that other contrasting-type marks can be equally effective as a signaling means. An electrical resistor 29 is secured between two depending legs 30 of the base member.

in a typical installation such as in the electrically heated hair curler dispenser, the temperature sensor is mounted such that only the upper surface 31 of the housing is visible. The fluorescent painted surface is not visible at ordinary room temperature due to the solid opaque state of the wax 27, but when a current is passed through the resistor 29 the heat generated therefrom will transform the wax to a liquid transparent state and the fluorescent paint will be visible through the surface 31. It has been found that with this device a onehalf watt carbon composition resistor will permit a lapse lll heatup time of 12 to minutes prior to melting the wax. Other types of heat sources can be utilized; the total elapsed time after heat is applied will be dependent upon the rate and quantity of heat generated. The temperature indicator as shown in FIGS. 6 and 7 consists of a housing 32 preferably made of A plastic material and containing therein a neon lamp 33 and two

electrical resistor elements

34 and 35. The space around the neon lamp is filled with a waxlike material 36 which is in a solid opaque state at room temperature. The resistor 34 is used to control the neon lamp current and the resistor 35 is used as the primary heat source. When power is applied to the terminals 38 the lamp gives ofi a soft glow through the semiopaque wax in the solid state; when the heating resistor 35 generates a sufficient amount of heat the wax melts and changes to a liquid transparent state. When the wax is in this liquified state the neon lamp gives off a bright normal glow and therefore serves as a signal means to indicate the elapsed or heatup time.

The temperature indicator can be mounted within the electrically heated hair curler dispenser so that only a portion of the surface such as at 39 is visible and will permit the observation of the bright rays from the neon lamp. The heat source and wax-melting temperature can similarly to the temperature sensor previously discussed, be chosen so as to control the elapsed or heatup time.

The usual mode of operation of this carrying case and dispenser would be to first pivot the cover from its closed position to a position behind the dispensing tray for supporting the dispensing tray in an upright position as shown in FIG. 3. The hair curlers already stored within the dispensing tray and positioned within the conductive track in the partition and side walls is now conductively engaged in by electrical circuit which will simultaneously and uniformly heat all the curlers. In this particular apparatus when used with the hair curlers of the previously mentioned copending application, a period of duration of lapsed time of between twelve and fifteen minutes is sufficient to bring the hair curlers to the operational temperature between l and fahrenheit. The user will be informed when these hair curlers are ready for use by the temperature indicator 23 which will so signal. Curlers can individually be removed from the dispensing tray at openings 18 by manually aligning the projecting end portions 17 of the curler with the slots 19. then withdrawing the curler from the track. Another curler will be gravitationally fed to replace the curler just removed.

The above cited embodiments are intended as exemplary for while they have described the invention with a specific implementation and embodiment other modifications thereof will be apparent to those skilled in the art.
