Patented Oct. 10, 1944 UNI TED STAT ES PATENT OFFICE 2,360,051 TOILET DEVICE Eric W. Ewescn, Halifax, Nova Scotia, Canada 7 Application July '18, 1941, Serial No. 402,916
This invention relates to toilet devices, particularly to devices for removing comedos or blackheads and similar occluded or included blemishes from the skin, and has for an object the provision of improvements in this art. This application is a continuation-impart of my .00- pending application, Serial Number 369,172, filed December 9, 194.0.
The invention aims to provide a simple, effective, inexpensive and easily operated device which can be used readily by the general public for its intended purpose Without danger of injury. One of the particular objects is to provide a soft tubular tip which will 'fit the skin tightly but which will not out or mar the skin. Another object is to provide a small point .or plunger which assists in locating the device correctly at the selected place on the skin, and which ejects the material from the tubular opening or barrel in which it lodges when removed from the skin. Another object is to provide a tapered barrel and piston which will create an effective vacuum to assist in removing the .material from the skin. Another object is to provide a device in which the mechanical parts are largely concealed to present an attractive exterior.
Other objects, vadvantagesand features of novelty will be evident from the following description of certain exemplary embodimentsof the invention which are illustrated in the accompanying drawing, wherein:
.Fig. 1 is an axial section of the preferred embodiment;
Fig. 2 is .a cross section on the line 22 of Fig. 1.;
Fig. 3 is an axial section of another embodiment; and
Fig. 4 is a cross section on the line 4-4 .of Fig. 3.
Referring first to the form shown in Figs. 1 and '2, this comprises a cylinder it] which i tapered at II to join .a small tubularportion or barrel i2 which is of .a size to receive the oily clots or blackheads removed from the skin. Within the cylinder there is .disposed a piston 43 provided with packing M, as of rubber, cupped leathor or the like, whichclosely fitswithin thestraight part of the cylinder to create .a difference in air pressure ora vacuum when thepiston is operated. The piston is tapered .to fit the taper i! so as to completely fill the space. This minimizes clearance and produces a better vacuum when the piston is operated. Thebodyof both the cylinder and piston may be .formed of a plastic material, and maybe attractively colored.
The upper end of "the cylinder [0 is closed by a cap 15 which :may besecured in any convenient manner, as by a-su-itable "adhesive, :as illustrated. The piston L3 is urged toward the lower tapered end of the cylinder by -a spring it which fits within a tubular recess 1| Tinthepiston and a telescopic tubular ,projection 18. carried by the cap l5.
To the outsideof the upper end of the piston there are secured, as by being formed integrally therewith, a pair of oppositely disposed project ons 19 which extend outWa-rdly through narrow slit-like axially elongated openings 2i] in the cylinder i0. Theprojections i9 and'the'cap I5provi'de means for engagement .by the fingers and thumb respectively, whereby the device may be operated byone hand. The projections are concave .ontheir ,lower side and the cap is concave on its upperside, the better to fit the fingers and thumb.
The end of the tip or barrel .12 will 'serve alone but it is of relatively hard material and may be somewhat uneven when molded so as to create some likelihood of injury to the skin. In order to eliminate this danger and .provide good contact with theskin .for a better vacuum, .a resilient tip .25 may he provided. This may comprisea short length of rubber tubing -.cut to length and pushed tightly ion the straight part of the tip until it engages the tapered portion. Th end of the rubber tip 25 extends slightly beyond the end of the tip 12 and contracts insize.
To thelower end of the piston there is secured a small plunger .26. .This normally extends out from the lower end of the barrel, like the lead of .a pencil. By placing it .on the spot to be treated, .thedevice is accurately centered for operation. Preferably, .the plunger is urged .outward by a light spring =21, .whereby aslight pressure against the skin will cause it to retract into the barrel. ltmay heretainedbyan enlargement 28 thereon and .a part 29 .on the end of the piston. The parts 13 and .29 may ibersecured together in any convenient manner inform .the assembly, as
. by a tight fit oradhesive, .as indicated.
In operating the .form shown in Figs. 1 and 2, the projections andcap are grasped between the fingers and thumb, and the end of the plunger is placed at the desired place on the skin. The entiredevice is then pushed down by the thumb until the plunger retracts into the barrel and the end of the barrel (or rubber tip) firmly engages the skin. The piston is it-henquickly pulled back by the fingers to cause the material "in the skin .to be drawn up into the barrel. The device is then removed and released from the finger grip, whereupon the material is ejected from the barrel by positive pressure of the piston under spring pressure and the assistance of the plunger. The plunger is positively moved with the piston until its end is about at the end of the barrel, thus forcefully ejecting any material in the barrel, even if air pressure created by the return of the piston is inadequate to do so.
In Figs. 3 and 4, there is shown a simpler modification in which a slighter vacuum may be employed, pressure on the tubular tip being practically suificient to cause the material to be ejected from the skin. Here the cylinder 3|] is tapered at 3| and provided with a tubular tip 32. The auxiliary rubber tip 33 is also shown. A cap 34 telescopically fits the outside of the cylinder, and a small interior tubular extension 35 secured to the cylinder. The cap may be urged away from the cylinder by a spring 36.
The plunger 31 is secured as by a transverse hinge pin or otherwise to light resilient leaf springs 38 which pass through opposite openings in the extension 35 so as to fulcrum on the edges of the openings and cooperate with surfaces 39 on the cap, whereby the plunger may be pushed up when pressed againstthe skin by pushing down on the cap, and will be pulled back to allow space in the barrel for material when the cap is pushed down further. A piston 40 secured to the plunger 31 operates in a cylindrical recess 4| to create a vacuum or pressure at the tip.
The outer skirt portion 44 of the cap may be slotted longitudinally at 43 and may be retained by any suitable means such as a pin or pins 42 secured in the cylinder 30.
The springs 38 may be integral and connected by a coiled central portion by which they are pivoted to the plunger. In Fig. 3 the normal position of the springs is shown in full lines, and their position when the plunger is raised is shown in dotted lines. The springs may be curled or provided with knobs on their outer ends to have a smoother camming action with the surface 39. It will be noted that the plunger 31 may be pushed up to the end of the tubular tip by a light push against the springs 38, the spring ends sliding out against the cam face in this action. For greater retraction of the plunger, the cap 34 is operated to move it down axially relative to the cylinder 30.
In the operation of the form shown in Figs. 3 and 4, the plunger is placed on the desired spot on the skin and pushed back by a light downward pressure on the cap. Then by continued heavier pressure on the cap, the tip is pressed against the skin to remove the plug therefrom, and at the same time the plunger is retracted further into the cylinder to allow the plug to be received. The barrel or cylinder 30 may be held between the fingers while the thumb is kept on the top of the cap 34 to hold the parts together while being removed from the skin. Later, when the fingers are released, the parts expand and the plug is ejected from thecylinder.
For greater simplicity, the piston may be omitted entirely, greater pressure being exerted on the tip to take the place of pressure and vacuum in removing the occlusions from the skin.
It will thus be seen that the invention pro- Vides a simple, safe, sanitary, inexpensive and efiicient device for removing plugs from the sebaceous glands of the skin.
