H. L. WELKER DENTAL CLEANSING AND MASSAGE DEVICE Filed April 17, 1934 gmw HARRY L- WELKER Patented Oct. 8', 1935 UNITED STATES PATENT, OFFICE l DENTAL CLEANSING AND MASSAGE nnvrcn Harry Logue Welker, Williamsport, Pa. Application April 17, 1934, Serial No. 121,011 1 Claim; (01. 15-227) This invention relates to a dental cleaning and ,massaging device. It has for its general object the provision of a flexible member of the.finger cot type having a rubbing strip for-cleansing the teeth and stimulating the gums, and carrying a charge of tooth paste which is made available incident to the employment of the device in its rubbing or'massaging capacity.
Another object of the invention is to provide a device of the character described in which the rubbing strip-defines aspace within which islodged a disintegrable or easily rupturable envelope or container containing the tooth paste. the paste being released either by dissolution of the envelope whe'n'the device is Wetor'rupture of the envelope by the bending of the finger.
Other objects of the invention will appear as the following description of a preferred and practical embodiment thereof proceeds. In the drawing which accompanies and forms .a part of the following specification and throughout the several figures ,of which the same characters of reference have been employed to designate identical parts: Figure 1 is a perspective view of the device of the invention positionedupon the finger;
Figure 2 is a perspective view of the device when not in use;
Figure 3 is a cross section showing the tooth so paste in a soluble or easily rupturable capsule; Figure 4 is a longitudinal section illustrating the tooth paste in a rupturable envelope;
Figure 5 is a longitudinal section illustrating the method in which the envelope shown'in Fig- 35 ure 4 is distorted to open the seam and loosen the tooth paste; and. r
Figure 6 is a. cross section taken along the lineB-GofFigureL 1 Referring now in detail to the several figures 40 the numeral I represents a finger cot which may be of rubber 'or any suitable textile fabric and being provided with a tab- 2 which when the cot is upon the finger may be pressed by the thumb as shown in Figure 1 in order to hold the cot in 45 place. The tab may be provided with a hole 3 facilitating the hanging up of the device when not in use.
The side of the finger cot is provided with a rubbing strip 4 preferably formed of a rough,.but
50 reasonably soft fabric of which turki'sh toweling may be considered an example. The strip-4 is the tooth paste which shall be impervious be fore the device is used. but which will disinte-- grate making the tooth paste available. The device is designed to be clipped in water while on the finger and to be rubbed against thegums 5 and teeth, the released tooth paste passing through the meshes in the fabric strip 4, permeating the same and making contact with the teeth.
The receptor for the tooth paste may be of 10 ,any desired construction having the .qualities of initial imperviousness and subsequent disintegrabilityor rupturability. .Figures 1 and 3 show a water soluble or rupturable gelatinous capsule 6 filled with toothpaste and the walls of which 15 will soften when the device is dipped in water permitting the capsule to be readily ruptured by slight pressure against the teeth, releasing the toothpaste.
Figure v6 shows a modified form of receptor 20 comprising a small flat envelope 1 of impervious substance such for. example. cellophane having 4 a weak rupturable zone constituted by the seam 8. The seam'side of the envelope of course faces the detergent strip 4. Eitherbefore or after the 25 device is .dipped in water, the'finger is bent as shown in- Figure 5 distorting'theenvelope's'o as to open the seam 8 and release the toothpaste.
While the invention contemplates primarily a dental cleaning and massage device containing I the receptor of tooth paste and packaged in a sanitary manner and designed to be used but once, it is within the purview of the invention to provide that the device shall be used repeatedly. To this end, the upper end 9 of the detergent strip 4 may be-left unsecured to the finger cot forming the mouth of an open pocket into which a fresh capsule or envelope may be slipped daily, or asoften as the teeth are cleaned.
While I have in the above disclosure described whatl believe to be a preferred and practical embodiment of the invention, it is to be understood that the details of construction as shown' and described are merely by way of exampleand notas limiting the scope of the invention as defined in the terms of the appended claim.
what-1 claim is:
A dental cleansingand massaging-device comprising a flexible finger cot, a rubbing strip extending longitudinally along one side thereof, a fragile disintegrable container having a tooth cleaning preparation therein; said container positioned beneath the strip and adjacent the wall of the finger cot, said strip forming a protective coveringfor said container. l6
