Application Api-ii s, 194s, sei-iai No. '18,958 11 claims. (cris-184) This invention relates to improvements in toothbrushes and has for an object the provision of a collapsible toothbrush which is clean and sanitary.

Another object of the invention is the provision of a collapsible toothbrush which, when in the closed position, has means extending lfrom one end thereof which enables the brush to be hung up.

open position (as shown in Figure 1) the portion 18 ofthe head forms aft in the open end 11 of the casing and its movement inwardly is stopped or vlimited by the bead or fillet 17 when it contacts the end of the casing. The head portion 18 has opposite depressions,

. concavities, or

open areas

20 and 21 formed therein Yet another object of ,the invention is the provision of a collapsible toothbrush which includes an open-ended casing, `a toothbrush having a head portion with an intermediate bead which forms' a stop to. limit the depth of insertion of said head vinto the end of the c asing both for the closed position and for the open position.

A further object of the invention is the provision u i a toothbrush of a casing having an open end and having the opposite end perforate, a head carrying an extension into which the bristles of the brush are embedded, said head having the opposite end arranged so that when the bristle end is inserted inthe casing, the device may be hung up, and any water remaining in the bristles may drain downwardly and exit. through said perforate en d.

Other objects and advantages of the invention will be apparent to those skilled in the art upon a study of the specification and the accompanying drawings.

Referring to the drawings, which are given by way of example:

Figure 1 is an exploded view, showing the open-ended casing and the brush having a head portion forming a fit in said open end and having an intermediate bead which forms a stop for limiting` the insertion .of the head into the handle both for the open and the closed positions;

Figure 2 is a perspective view of the brush of Figure l, shown in the closed position;

Figure 3 is a view` of the opposite end of the casing showing perforations therein;

Figure 4 is a perspective view of a modification wherein the external portion of said head, when the brush is in the closed position, has a passage therethrough permittingthe device to be hung upon a hook or the like;

Figure 5 i-s a further modification, similar to Figure 4, except that both the casing and the head are oval in cross-section and the external portionof the head, like Figure 4, has a passage therethrough by means of which the device may be hung up;

Figure 6 is a further modification of the arrangement shown in Figure 4, wherein the external portion of the head, when the brush is closed, has a passage therethrough; v

Figure 7 shows a further modification in which the exterior portion of the head, when the brush is in the closed position, is somewhatcylindrical in form; and

Figure 8 is a fragmentary viewof the head 16a of J Figure 4 showing the spaced lateral passages on each side of the central bead formed in the head.

Referring first to Figures 1, 2 and 3, the device consists of a casing 10 which is rectangular in cross-section and which has an open end 11 and a closed end 1 2. The closed end has a plurality vof perforations 13 formed therein. The removable member has a shank 14 carrying brush bristles 15. Preferably formed integral with the shank 14 is a head or handle portion 16 which is divided by a bead 17 into portions 18 and 19. When the end bearing .bristles is inserted into the casing, the portion 19 of the head forms a fit in the end 11 of the casing and the inward movement of the head 19 is stopped by the bead 17. When the brush is in the closed end 32 which also may be perforate.

defining boundary fins or walls leaving a web 22 therebetween. The portion 19 has opposite depressions or

concavities

23 and 24 formed therein, likewise defining boundary fins or walls leaving therebetween a solid web 25. A lateral web 26 defining a partition, stop or boundary joins the

webs

22 and 25 more or less and also joins the head 17. On the opposite face of the head portion 19, a web forming a part of the partition, stop or boundary 27 connects with the

webs

22, 25 and the bead 17.

Due to the formation of the

depressions

20 and 21, the user may get a firm gripon the head to open the brush up, even with wethands. Now, when the brush is open and it is desired to close it, the user, due to the presence of the

depressions

23 and 24, may'also get a good4 grip on the head, even with wet hands.

Referring now to Figure 4, which'is identical with the device shown in Figures 1 and 2, with one exception, the outer portion 18a of the head 16a has a passage 28 therethrough which venables the user to hang the brush up when it is in the closed position. Further details of the head 16a are shown in Figure 8, wherein the portion 23a of the head constitutes a passage or open area therethrough.. With this arrangement, like the 'arrangement shown in Figures l and 2, the user may get a firm grip on the head for removing it. v

. Figure 4 might alsobe considered identical with the device shown in Figures 1 and 2 with the exception that both the

webs

22 and 25 are omitted, thereby providing crosspassages in bcth portions of the head adjacent to and on either side of the bead 17a Referring now to Figure 5, the brush is similar to Figures 1 and 2, except. that the casing 30 is curved or oval in cross-Section, and has an open end 31, and a The head 33 is also-oval or curved in cross-section to form a snug fit Vin the open end 31. The head 33 is provided with a bead 34 which divides the head into two portions, one of which is positioned within the open end 31 and the other of which is designated by a numeral 35. The head 33 also has a rounded end 36 and a passage or open area 31 therethrough makes it easy for the user to operi the brush, and it also 'enables the user to hang the brush up with the perforate end of the casing extending downwardly so that any water on the brush may drain out.

In the modicationishown in Figure 6, the structure may be identical with'that of Figures l and 2, with the exception that the portion 18h of the head which is outside of the casing 10b when the brush is closed, is pro-- vided with a peak'38 having a passage or open area 39 therethrough.

In the form shown in Figure v7, the exterior portion 18e of the head has a rounded surface 40, and a round passage or open area 41 extends therethrough, thereby facilitating the removal of the head and brush element from the casing 10c and also permitting'the user to hang the brush up when the same is closed.

Although we have herein shown and'described a number of embodiments of the invention, it is obvious that numerous changes may be made in the arrangements herein shown and described within the scope of the following claims.
