3 Claims. (Cl. 128-295) The present invention relates to medical apparatus for incontinent patients, and has particular reference to a novel construction for a male urinal.
The principal object of the invention is to provide a one-piece male urinal having a closure sheath.
Another object of the invention is to provide a manufacturing procedure for making a male urinal with an integral closure sheath.
An additional object of the invention is to provide a one-piece male urinal which has thin wall sections and is very comfortable to wear.
With the above and other advantageous features in view, the invention consists of a novel method of manufacture and a novel arrangement of parts more fully disclosed in the detailed description following, in conjunction with the accompanying drawings, and more specifically defined in the claims appended thereto.
In the drawings,
Fig. 1 is a perspective view of an illustrative male urinal construction embodying the invention;
Fig. 2 is a vertical section through the urinal of Fig. 1;
Fig. 3 is a side view of the urinal body blank after dip forming;
Fig. 4 is a top plan view of Fig. 3;
Fig. 5 is a side view of the body blank dipping form;
Fig. 6 is a section on the line 6-6 of Fig. 5;
Fig. 7 is a perspective view of a modified construction;
Fig. 8 is a vertical section through the urinal of Fig. 7;
Fig. 9 is a vertical section through the urinal body blank after dip forming;
Fig. 10 is a side view of the body blank dipping form; and
Fig. 11 is a top plan view of Fig. 10.
It has been found desirable to provide a one-piece male urinal which includes a cone-shaped closure sheath and has thin wall sections, whereby the urinal fits better and is more comfortable. To this end, I have devised a dipping form of special shape on which a urinal blank is dipped having a body with an outer wall, and an integral inwardly foldable cone-shaped sheath, the body at its juncture with the sheath being inwardly flanged to permit a smooth folding of the sheath into the body.
Referring to the illustrative embodiment of the invention shown in Figs. 1 to 6, the urinal 10 includes a coneshaped body 11 having an inwardly folded conical sheath 12, see Fig. 2; the body is provided with thigh straps 13, 14, and with a waist-strap or straps 15 of standard type, and has a valve connector element 16 at the lower end communicating with a conduit 17 of a leg bag or the like, not shown.
The urinal is made on a form 18, see Fig. 5, of special shape, which has a body portion 19 of conical shape and a sheath portion 20 of conical shape angularly positioned with respect to the body portion, the angle between the sheath portion axis and the body portion axis being slightly greater than 90 degrees, the base of the sheath portion being smaller than the base of the body portion, see Fig. 6, whereby an annular flange area 21 1s provided.
When the form 18 is dipped in standard manner in latex or other suitable rubber solution and in coagulant until a latex coating of desired thickness is obtained, and the coating is stripped from the form after the usual air curing, the urinal blank 22 resulting is as shown in Figs. 3 and 4. The lower end 23 of the body 11 and the outer end 24 of the sheath 12 are trimmed, the lower end of the body being shaped as an outflow connection 25, and the sheath 12 is folded inwardly as shown in Fig. 2, the coating portion between the base of the body and the base of the sheath at the flange area 21 forming a narrow fold 26.
The straps 13, 14 and 15 are of suitable material, preferably of latex, and are cemented to the outer surface of the body 11 as illustrated, the outer strap portions being provided with openings 27 for receiving buttons or the like. The valve connector element 16 may be of any suitable type for closing the urinal against drainage except when opened for this purpose, and the shield may be cut 3) fit snugly and close the top of the urinal against out- A modified construction for the urinal is shown in Fig. 7, the urinal 28 including a body 29 having an upper inlet opening 30 and a lower outflow connection 31 which is preferably equipped with a shutoff valve device 16, the body 29 having an upper narrow edge 32 and an inwardly folded cone-shaped sheath 33, and having integral tabs 34 extending outwardly from the outer surface thereof to which tubular waist and thigh straps 35 are secured.
The urinal 28 is manufactured by dipping a form 36, see Figs. 10 and 11; having a body portion 37 with a connection extension 38 at its lower end, the upper end of the body portion having laterally extending tab plugs 39 and being annularly recessed or indented as indicated at 40 to provide an annular flange from which a coneshaped sheath portion extends upwardly. The form 36 is dipped in any suitable rubber solution, preferably a latex solution, and the coating is coagulated and air dried and then stripped, providing a urinal blank 41, see Fig. 9, with a cone-shaped sheath which is connected to the upper end of the body by an inwardly extending annular flange, whereby the sheath is readily folded inwardly as shown in Fig. 8.
Latex is preferred as the coating material solution, but any suitable rubber or plastic solution or dispersion may be used, having the characteristics of providing a hollow article of the type described which is flexible but strong and which is not affected by the urine. Any valve closure may be used for the outflow connection, the preferred valve closure being of the type shown in my application Serial No. 401,993 filed as of even date herewith and now abandoned.
Although I have disclosed specific embodiments of my invention, it is obvious that changes in the size, shape, and proportions of the parts, and in the material used, may be made to meet different requirements for male urinals and the like, without departing from the spirit and the scope of the invention as defined in the appended claims.
