s Claims. (ci. 15-110) The present invention is directed to a massage and brush type single-use toothbrush. Y
Massage of the gums is most desirable if healthy gum tissues are to be retained. ln fact, there has been developed a division of dentistry known as periodontia which deals with diseases of the periodontal tissues. Researchers in this field haveestablished that massage ofthe gums is necessaryl both to avoid many common ailments, and as a therapeutic treatment for many gum conditions.
However, the conventional toothbrush is not suitable for the massage of gums, and in fact the use of a conventional toothbrush by unskilled persons for the massage of their gums may lead to injurious consequences.
This invention has as an object the provision of a novel toothbrush.
This Iinvention has as another object the provision of a toothbrush which may be used Vfor both' the brushing of the users teeth and the massaging of his gums. Y Y
This'l invention has as yet another object the provision of a toothbrush having a single-use toothbrush head which contains its own supply of dentifrice.
This invention has as a different object the provision of a single-use toothbrush having disposable toothbrush heads, which heads occupy a comparatively small volume when stored prior to use.
This invention has as yet another object the provision of a toothbrush whose toothbrush head is sterile prior to use.
Other objects will appear hereinafter.
For the purpose of illustrating the invention there is shown in the drawings forms which are presently preferred; it being understood, however, that this invention is not limited to the precise arrangements and instrumentalities shown. l
Referring to the drawings wherein like reference characters refer to like parts:
Figure l is a fragmentary perspective View of the toothbrush of the present invention.
Figure 2 is a section on line 2-2 of Figure l.
Figure 3 is an exploded perspective view of another embodiment of the toothbrush of the present invention.
Figure 4 is a sectional view taken on line 4 4 of Figure 3.
Figure 5 is a sectional View showing the toothbrush head of the present invention in its enlarged condition after being wet.
Referring tothe drawings and initially to Figures 1 and 2 the toothbrush of the present invention is designated as and comprises the handle 12 which includes the customary shank 14, which due to its conventional construction is but partly shown in Figure 1. The handle 12 includes toothbrush head retention means 16 which in the embodiment of Figures l and 2 comprises a clip having jaws 18 urged together by the spring 20. Toothbrush head retention means 16 includes a thumb engaging member 22 upon which pressure may be exerted by the user of the toothbrush to overcome the action of the spring 20 and spread the jaws 18 apart. In the Y 2 absence of pressure bythe user on thumb engaging member 22 suiiicientV to overcome spring 20 the jaws 18are normally urged together. Y
vThegtoothbrllsh head 24 of the present'inventionmay be'emplonyed inboth the toothbrushembodiment of Fig-4 f ures. 1-"and'2 and the toothbrush embodimentv of Figr 26 comprises expandable cellulose, such .as the so-called" The folded outside member 26 should be formed of suchA material that the same expands to more than double ures3 andf4.l YSuch. toothbrush head `24v comprisesf a folded outside member 26 integrally formed from a material which expands greatly when wetted with water.

This material when wetted expands laterally to more than doublerits original size andyields a cellular, porous cushion-like material which is ideally suited for the massaging of the users gums.
its original dimension in at least one direction on being wetted with water. Preferably, the material of which folded outside member 26 is made should berspongy in nature and resilient and cushion-like in its physical characteristicsV when wetted with water.
The free uppermost edges of folded outside member 26 may be scalloped to form the projections 28. The scalloping of folded outside member 26 provides for the :facile expansion of folded outside member 26 when wetted, as will be more fully explained below.
A plurality of bristles 30 are disposed intermediate the folded outside member portions 26 of toothbrush, head V24,such bristlesbeing disposed with their longi-l f vtudiii'al axis extending generally vertically. The uppermostends of bristles 30 lie generally in the same plane as vthe uppermost portion of the scalloped projections 28. The bristles 30 carry the dentifrice 32 which may be disposed at the base of bristles 30, as on the Ifloor formed by the bight 33 of the folded outside member 26. Dentifrice 32 may be disposed along the bristles 30 and may extend to their uppermost portion. The dentifrice 32 may be of the type which foams when wetted with water, or which is otherwise activated when wetted with water. A Wide variety of conventional dentifrices are available in the form of powders and may be used in toothbrush head 24. An adequate supply of dentifrice 32 may be carried on or adjacent the bristles 30, and in connection with the amount of this supply compensation may be had for dentifrice absorbed or lost to the folded outside member when the same is expanded.
Stitching 34 disposed near the bottom of toothbrush head 24 may be relied upon to retain the folded outside member in its folded disposition withl the bristles 30 secured intermediate the folded portions of such folded Y outside member.
As shown in Figures 1 and 2 the toothbrush head 24 is of vsomewhat greater length than the length of the jaws 18 so that exposure of the users gums to the ends of the jaws 18 is not possible. Y
The toothbrush head 24 is withdrawn from its package,
whichV is preferably inthe form of a magazine. The t toothbrush heads 24 may be individually packaged in sterile. envelopes. Sterilization of thetoothbrush V heads outwardly, generally fan-like, the blunted surfaces are available as a surface for the massaging of the users gums. Simultaneously with the wetting of the tooth.- brush head 24 the dentifrice 32 is activated permitting the user to brush his teeth with the bristles 30.

Referring now particularly to Figure 3, there is shown therein another embodiment of the toothbrush of the present invention designated generallyas 38, In this embodiment, the toothbrush 38 is provided with ahandle 40 having a shank 42 with a narrowedrextent or neck 4.4between the shank 42 and the head end 46 of handleA 40. Head end 45 of handle 40 isV characterized by the provision of longitudinal side anges 48 which form a pair and enclose a longitudinal pocket or way 50 open at its extreme end 52 for the sliding reception andaremoval of the toothbrush head `24. The pocket 4or Way 50 is provided with a stop shoulder 54 at its innermost end against which the toothbrush head 24 is engaged.
The present invention may be embodied in other speciiic forms without departing from the spirit or essential attributes thereof and, accordingly, reference should be made to the appended claims, ratherl than to the fore.- going specification as indicating the scope of the invention.
