May 19, 1959 R. R. ROSHOLT COMBINATION CAPPED COMB AND APPLICATOR TUBE Filed Oct. 26, 1956 INVENTOR.

Pa VMDND E! Pas/104.1- BY M11, MQO'LM U it a e a -e COMBINATION CAPPED COMB AND APPLICATOR TUBE This invention relates to a combination capped comb and applicator tube.

More particularly stated, the invention relates to the provision of a comb-like end of a tubular package providingre silient comb teeth shaped to provide both scraper and rounded applicator surfaces.

-An object of my invention is to provide a tubular package for a semi-soft, but form sustaining material in which the material maybeadvanced toward an end of the tube which may be used as an applicator, especially adapted to apply the material to surfaces over which the end of the tube may be advanced in selected positions and attitudes whereby to accomplish alternatively scraping or massaging action. Furthermore, I have made it possible to use the special configurations of the applicator end of thetube to cooperate with a cap closure which will fully enclose comb-like portions of the applicator end of the tube and, by using the springy characteristics of the comb teeth, to hold the cap in a tightly closed relationship about thecomb, the teeth, and about the slots between the comb teeth.

Fig. 2iis a side elevation of my device with the cap in closed position, most of the tube and part of the cap being broken away to show the parts in vertical section.

Fig. 3 is a fragmentary view in vertical section of the upper portion of the tube with the cap in an intermediate position as it is being applied to the tube.

Fig. 4 is a somewhat diagrammatic view in section of the applicator end of my device in position for treatment of the scalp of a user, the hair and scalp of the user being shown somewhat diagrammatically in vertical section.

Fig. 5 is a view similar to Fig. 4, but showing the applicator end of my tubular comb-like device tilted in a scraping operation or applicator operation depending upon the direction of movement.

It has been common heretofore to provide a tubular container or package wherein as shown in the lower portions of Fig. 2, a tubular container has a slightly inturned lower flange 11, but the lower end of the tube is otherwise completely open. A slidable bottom wall 12 has upturned flanges 1314 closely fitted to the interior surfaces of the tube 10. Within the tube, any one of a large number of semi-soft contents 15 may be stored in readiness for use and may be extruded from the top of the tube when the user pushes upwardly upon the slidable bottom member 12. It is to such an environment that my invention is principally introduced, since it is with respect to the upper end of the tube 10 and the provision of a special cap for such a tube that my invention relates.

As shown most clearly in Fig. 1, I provide longitudinal Slots 16 extending downwardly from the top margin 17 ice of the tube. These slots are of suflicient length to pro:

vide comb teeth 18 between the slots and to permit of springy inward deflection of the teeth 18 for reasons which will be described below.

The material of which the tube 10 is made may be of many diiferent selected substances, but I prefer metals or plastics which have some resilience as will be apparent from the following description and including the resilient characteristic referred to above. At the upper end of the tube which I will denominate the applicator end, I provide in the configuration of the extremities of the teeth 18 a bead 20 which is discontinuous because of the slots 16. and cylindrical with the result that the applicator end of the tube and the extremities of the comb-liketeeth have rounded outer surfaces merging toward scraper.

margins at the line where the rounded surfaces meet the interior cylindrical surfaces referred to.

Approximately at the lower ends of the slots 16 be-.

same, but need not be accurately so, as will be under-.

stood from the description below. p

A cap 25 includes a side wall 26 and atop wall 27 exteriorly shaped in any suitable manner but providing interiorly adjacent the top wall 27 a groove 28; The configuration of the groove 28 is such as to provide a cam surface 29, so disposed as to bear on the under surface of bead 20 when the cap is in closed position upon the applicator end of tube 10. The length of the side walls 26 in a direction longitudinal of the tube 10 are such that lower margin 20 of the cap side wall is brought to bear against cap abutment head 21 snugly when the cam action between head 20 and the shoulder at 29 causes the cap to bear downwardly under the. re-

' silient reaction ofthe comb teeth.

As shown in Fig. 3, each of the comb teeth 18 springs inwardly of the tube as the cap is thrust downwardly upon the applicator end, since the inner surface 31 of the walls of the cap 25 bear upon the rounded outer surfaces of the comb teeth. Then as the cap is thrust still farther downwardly to position the cap shown in Fig. 2, the resilient teeth force the bead surfaces of the bead 20 into the groove 28 for the cam action against shoulder 29. Thus the cap is held firmly against cap abutment head 21.

p A tab 35 is provided upon the outer surface of wall 26 of the cap 25 so as to facilitate the removal of the cap. An initial upward movement upon the tab to institute a releasing cam action by forcing some of the immediately adjacent comb teeth inwardly provides for ready release of the cap as will be clearly understood.

The massaging and scraping alternative actions of the applicator end of the tube with respect to scalp surface 36 and hair 37 will now be readily perceptible if the applicator end of the tube with the cap removed is applied to the scalp 36 as shown in Fig. 4. The movement of the tube in the direction indicated by the arrow will cause the rounded surfaces 20 of certain of the teeth to massage the surface of the scalp, whereas the scraper shaped portions of the teeth involving the margins 17 will accumulate a certain amount of the material 15 as shown at 15 which is removed from the scalp. At the same time material 15 which has been advanced in the tube to the degree desired by the user may be rubbing upon the hair 37 in such a manner that the comb teeth will apply the Patented May 19, 1959 Interiorly, the walls of the tube are straight material 15 not only to the surface of the hair, but also will work it down toward the scalp.

If the user wishes only to scrape the scalp with the comb teeth as shown in Fig. 5, he may do so, or it is, of course, possible to move the applicator in the other direction and massage the scalp with the scraping action. The tilting of the tube and the applicator end thereof in the possible alternative positions and directions can be used to perform lifting or penetrating action with respect to the material. Obviously, the degree to which the material 15 is advanced or extruded toward the applicator end of the tube will determine the quantitive delivery of the material by the comb teeth to the hair or scalp of the user.

In a particular commercial adaptation of my invention to the special purpose of applying hair dressing pomade, the tube is made of relatively flexible plastic 1%" in external diameter, 1%," in internal diameter, the

beads

20 and 21 have an extreme diameter of 1%", and the slots 16 are A" long. The other dimensions as shown in'the drawings are proportionate to those given, and it has been found that the cap made of the same material as the tube; namely, polyethylene tightly closes the margins 30 of the cap against the abutment head to prevent accidental escape of the pomade when the cap is in closed position. Obviously my device is not only suited to the application of pomade to the hair, but also may be used for other substances including medicament and the device may, therefore, be said to be useable for application of any treatment material. The shape of the tube may be circular, oval, or even rectangular as will be understood from the above description, and the arrangement of the teeth for any tubular configuration may be referred to as crown shaped.
