Description

BACKGROUND

The present invention is directed to a toothbrush or other toiletry article that provides a unique combination of utility and aesthetics. Existing methods of applying applications on such article handles includes the use of decals, ink imprinting, laser imprinting, and labels applications. Concerning toothbrushes, since toothpaste is an aggressive and abrasive substance, it is common that after using the toothbrush several times, the applications come off partially or entirely. It is desirable to provide applications, such as images and or text/logos, that will durably remain on the toothbrush despite heavy use around abrasive substances. Although a flosser, hair comb or brush is not normally surrounded by or used in conjunction with such abrasive substances, repeated use and contact by oily skin can produce a similar wearing of any applications that may be provided

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

According to an embodiment of the invention illustrated in the Figures, FIG. 1 depicts a longitudinal section view through a molded and assembled toothbrush. A toothbrush 1 has head portion 2 that contains the bristles of the toothbrush 1, a handle part 3 that is gripped by a user when brushing his or her teeth, a plastic pocket insert 4 that fills in a pocket 5 in the handle 3 having a gate area of a soft rubber-like material such as thermoplastic elastomer (TPE) or other similar material that is often used on toothbrush handles to ensure a solid grip and for aesthetic reasons. A picture insert 6 having a graphic illustration is disposed in the bottom of the pocket area 5 and is covered by the plastic pocket insert 4. The pocket insert 4 may be made of a clear, translucent, or opaque material.
A pocket bridge 7 is filled with the soft rubber-like material that lies between the plastic insert 4 area and a ribbed area 8, 9. The ribbed area 8, 9 has a portion on a top part 8, and a ribbed area on a bottom part 9 of the toothbrush 1 for contact with a user's thumb that is filled with the soft rubber-like material. FIGS. 27 and 28 show an alternate embodiment in which the ribbed area 101 comprises a plurality of protrusions 100. The handle part may comprise a finger grip for the ribbed area of which a portion is on a top part of the handle part, and another portion is on a bottom part of the handle part, the finger grip portion comprising the soft rubber-like material. In an embodiment, the length of at least some of the protrusions is greater than a distance separating center points of the protrusions. In another embodiment, the length of the protrusions on a top side of the toiletry article differ from a length of the protrusions on a bottom side of the toiletry article.
The image area 10 is present on the bottom part of the toothbrush 1 and is clear so that the picture insert 6 can be seen when viewing the brush from the bottom side.
FIG. 2 shows a top view of the toothbrush 1 having molded letters 20 on the top of the inserts, which can represent, e.g., a logo or company name. These letters 20 may be surrounded by the soft rubber-like material 21 and may project above, be level with, or slightly depressed from the surface of this soft material 21.
FIG. 3 shows a bottom view of the toothbrush 1 with picture 6 visible through the clear handle of the toothbrush. The handle 3 may be made of a clear or translucent plastic material, or only portions of the handle 3 may be clear or translucent such that ambient light can provide illumination to the picture 6.
FIG. 4 is a top view of e.g., the clear handle 3 prior to the bristles being added (bristle holes not shown). A bottom portion of the pocket for the gate 31 holds the injected rubber-like material that is above the bottom of the pocket 30 for the plastic insert. This configuration prevents a disturbance of the flat picture insert 6 in the case where the rubber-like material is directly molded without the plastic insert installed. An identified position 31 indicates the location of the gate 32 for the rubber-like material. A pocket for the bridge 33 connects the pocket 35 for the rubber-like material. The rubber-like material is designed so that it is held firmly in place on the handle 3, with the use of through-channels, inversely tapered holes, shrinkage, or the like.
FIG. 5 is a longitudinal cross-section view of the clear handle 3. The pocket 36 is connected through the bridge 33 with the pocket 35. A gap (34, FIG. 4) may be placed on the bottom of pocket 35 which connects upper and lower pockets in the handle 3 for the rubber-like material with ribbed areas (8, 9, FIG. 1) and keeps the ribbed areas 8, 9 connected together and affixed to the handle.
Various cross-sectional shapes of the clear handle 3 may be provided to enhance the picture 6 in various ways. FIG. 6 is a cross-sectional view perpendicular to the longitudinal section of the toothbrush 1 having a convex shape 38 of the handle 3. Such a convex shape 38 creates a magnifying effect on the picture 6 disposed therein. FIG. 7 is a cross-sectional view perpendicular to the longitudinal section of the toothbrush 1 having a flat shape 39 of the handle 3. In this configuration, the distortion/lensing effect is minimized, thereby presenting an accurate sized view of the picture 6 disposed therein. FIG. 8 is a cross-sectional view perpendicular to the longitudinal section of the toothbrush 1 having a concave shape 40 of the handle 3. Such a concave shape 40 creates a shrinking effect on the picture 6 disposed therein.
FIG. 9 is a side view of a plastic insert 50 having embossed letters 51 on a top surface of the insert. FIG. 10 is a top view of this plastic insert 50 illustrating these letters 52.
FIG. 11 is another embodiment of the toothbrush 1 with two images placed on two sides of the insert 40. This design has clear handle 3 filled with a clear material 41 in the pocket area of the clear handle and in the ribbed pocket area 42.
FIG. 12 is top view of this embodiment. A first image 45 present on one side of the insert 40 is clearly seen through the clear material 41 molded into the handle 3. Clear material fills rest of the pocket in the handle 3 through bridge 43.
FIG. 13 is bottom view of the same handle with a second image 46 seen through the clear handle 3. The pocket 30 in the clear handle 3 (FIG. 4) is not symmetrical. This design eliminates a possible mistake in placement of the insert with picture 46 into the pocket of clear handle 3. The non-symmetry may lie about an axis defining the length of the brush, its width, or its height—this non-symmetry can be used for visual aesthetic purposes as well as to assist in the assembly of the device.
FIG. 14 is another embodiment of the toothbrush 1 with a plastic insert 48 placed on the top of the flat insert 40 having pictures on two opposite sides of the insert 40. This toothbrush design has part of the handle 3 filled with soft rubber-like material 49. In this case, gate 50 for injecting the soft rubber-like material into the clear handle is moved further up the handle closer to the bristle portion to the location indicated by reference character 50 on in FIG. 14. FIG. 15 is a side view of the plastic insert 48 illustrating a truncated tapered shape that may be used, e.g., to assist in the insertion into the handle 3. FIG. 16 is a top view of the plastic insert 48 having an exemplary shape to match the pocket of the handle. Such a non-symmetrical design of the insert 48 can help to eliminate a mistake in the placement of this plastic insert 48 and insert with picture 46 into the pocket of clear handle 3.
FIG. 17 is a cross-section of the handle 3 at the section having the picture insert 62 in which the soft rubber-like material 63 wraps around a part of the handle for gripping or aesthetic purposes. The plastic insert 60 may be clear to permit light to enter on the back side of the picture. In the embodiment shown, the handle 3 has a convex 61 shape to it.
FIG. 18 illustrates an alternate embodiment for the insert 50 with, e.g., raised lettering 51 on it, where the bottom portion of the insert 50 has a latching mechanism 65 that permits the insert to grip the handle 3 with a correspondingly shaped receiving portion of the pocket (not shown) to ensure that the insert 50 does not fall out. In the embodiment illustrated, the protrusion 65 on the tabbed portion is pressed inward during insertion, which is permitted by adjacent gaps 66 in the insert 50. When the insert 50 is in place in the handle 3, the protrusions flex out to hold the insert 50 in place.
FIGS. 19 and 20 illustrate embodiments of the invention that are applied to a souvenir comb 70. In this embodiment, the molded letters 71 are formed in a similar manner to those shown in FIG. 2 for the toothbrush, and may be surrounded by a soft rubber-like material or possibly a clear material 72. FIG. 20 represents an embodiment similar to that shown in Fig, 19, except that a graphical picture 73 is inserted. Alternately, it is possible that FIG. 20 reflects an opposite side of the same comb 70 shown in FIG. 19. An insert may be utilized to provide the molded letters 71 and/or the graphical picture 73.
Similarly, an embodiment applied to a souvenir hair brush 80 is illustrated in FIGS. 21 and 22. FIG. 21 shows a brush 80 having a handle 81 in which molded letters 82 are formed in a similar manner to those shown in FIG. 2 for the toothbrush, and may be surrounded by a soft rubber-like material or possibly a clear material 83. FIG. 22 represents an embodiment similar to that shown in Fig, 21, except that a graphical picture 84 is inserted. Alternately, it is possible that FIG. 22 reflects an opposite side of the same brush 80 shown in FIG. 21. An insert may be utilized to provide the molded rubberlike material 83 and/or the graphical picture 84.
FIGS. 23-26 illustrate embodiments of the invention that are applied to a souvenir flosser 90. The handle 3 is similarly constructed to the handle of the toothbrush embodiment illustrated in FIGS. 1-18. Additionally, the flosser has a head region 92 comprising the floss 93 itself, as well as a knob 91 used to hold the floss taught. FIG. 24 shows the knob 91 comprising a floss wrapping area 94 as well as friction teeth 95 for floss retention (also shown enlarged in FIG. 26). FIG. 25 illustrates a side view of the knob 91 having a capping portion 96 that covers the friction teeth 95.
