Patented Dec. 16, 1952 UNITED sTATEs PATENT OFFICE 2,621,780 TOOTHBRUSH PROTECTOR Ren Silva Triana, Miramar, Marianao, Cuba Application July 10, 1951, Serial No. 235,930 Y In Cuba April 20, 1951 1 Claim. 1

This invention relates to a casing for the accommodation of tooth brushes after use and its object is to keep the bristles of the tooth brush in their original erect position so that they may render a good cleaning service, as I have noticed that after some time of use the free ends of the bristles are bent down and aside and those of one row become entangled with those of the next row, thus losing their original erect vertical position; its points forming an arc do not render the required service of cleaning the cavities and interstices of the teeth.

Therefore, to eliminate this deformation of the bristles and thus extend the duration of the tooth-brush I have invented a protecting casing which consists of an elongated box provided at one end with the housing for the bristle end Of the tooth-brush and the rest of the box to be occupied by the handle, said housing being provided with one or more vertical walls which are parallel to the side walls of the box; between these walls are closely inserted the longitudinal rows of bristles, thus forcing the ends of the bristles of one row to be maintained separated from the next parallel row; owing to the contact of their ends with the separating walls, they will be maintained erect while drying.

In the annexed drawing illustrating a preferred embodiment of the invention, as applied to a two rows of bristle tooth-brush:

Fig. 1 is a side elevation of the box.

Fig. 2 isa cross-section on line A-A of Fig. l.

Fig. 3 is a cross-section on line B-B' of Fig. 1.

Fig. 4 is a cross-section on lines C-C and D-D of the same Fig. l; and

Fig. 5 is a top View of the casing.

AS shown in the drawing, the box is formed by an elongated casing of rectangular section adapted to contain a tooth-brush, which box presents an opening g-.g at the one end; the opposite end is provided with a central wall l which extends from the upper wall 2 reaches vertically down to approximately the middle of the height of the box (as shown in Figs. l and 2), the forward end of said wall having the shape of a wedge 3, and its rear end contacting the end wall of the box. The side walls 5 of the box are backwardly reduced in funnel-like form 5 from about the middle part of the box, as indicated by the dotted lines in Fig. 5. Said side walls 5 are provided at the rear end with air circulation holes 4 for drying the bristles, which holes may be also provided in the upper, lower and end walls.

Likewise the number of walls I will vary ao- 2 cording to the number of rows of bristles, and the width of said walls will also depend on the distance between the parallel longitudinal rows of bristles.

At the end of the box denoted with letters g-g' a detachable cover may be provided.

When introducing the tooth-brush through this end with the bristles extending upwards the brush goes through a space which has the same width up to sections C-C and D--D; from here and through section C-C the space is narrowed, and continues to get narrower until it reaches section B-B', where it remains uniform until the end of the bar and of the box.

The inside width of the bristle end of the tooth-brush is reduced to 0.65 cm., which is the same distance as the one between the twoouter faces of the bristles rows prior to the use of the brush if the bristles are bent aside through its use, they will be returned to their original erect position when introducing the tooth-brush in the casing, because, when the bristles pass through section C-C' they are compelled to reassurne their original shape, which is finally reached when reaching section B-B.

Again I wish to state that the tooth-brush used in this case has only two rows of bristles.

After passing 0.5 cm. of section B-B, the tooth-brush meets a wall `I extending downwardly along the casing and through the center thereof from the upper wall 0.75 cms. there is a wall of 0.1 cm. of width, of wedge form with an angle of 30 degrees. The width of this wall is equivalent to the distance separating the two rows of bristles, which is `also of 0.1 cm., and the functions of this central wall :are the same as that of the two side walls, that is, to maintain erect the bent points of the bristles. The wedge point of this central wall is to aid the inner side of the rows of bristles to get erect more easily, as the first part of the wall which penetrates between the rows of bristles is the lower pointed part which thus continues erecting up the bristles while the tooth-brush is being pushed in.

The wedged form of the central wall may be also applied to the side walls for effecting the same function of erecting the bristles from down up.

'Obviously the box may be made of any convenient material such as to the so--Called plastics, which may be resistant to water, tooth-pastes, mouth lotions, disinfectants, etc., and such other products used with tooth-brushes.

I claim:

In a toothbrush holder a rectangular casing 3 open at its forward end to lodge therein the handle of the toothbrush, at least one intermediate wall inside of the other closed end of said casing, the upper edge of said Wall fastened to the upper side of said casing and extending perpendicularly from the upper Wall until about a half of the distance of the height of said casing and extending in longitudinal direction for about a length equal to the length of the row of the bristles, the forward end of said intermediate Wall being wedge-shaped, the side Walls of the casing in the middle part of the same being funnel-shaped and extending backwards approx-V imately to the wedge formed end of said intermediate Wall.
