Abstract

ABSTRACT
A disposable urinal which is expendable and intended to be destroyed after use. The urinal is constructed of molded fiber pulp material such as that used in egg cartons and is formed of mating upper and lower sections which are glued together to form the complete urinal.

Description

Thc uso of reu~able urin~ls constructed o~ metal or rigid pla~tic in hospitals and other institutions presents a number of disadvantages4 Following use~ they mu9t be emptied~
¢leaned and ~terilized and then stored ~or ~urther use~ In add~tion, personnol must be hired to car~y out the above menial ta~ks.
In an attempt to overcoma the above disadvantages, a number o~ disposable urinal~ have been developed as dlsclosed, ~or instance~ in U,S. Paten~ 3,163,868; 3,3?9,g73; 3~579~653 and 3~731~8690 .However~ the urinals dis¢losed in the~e patenks aro ~ormed ~rom oa~dboard, plastic material and paper which materi~ls require waterproo~ing or must in¢lude impervious liners to pr~ent leal~age~ In addition~ the patented urinal~
are rormed from complicated collap~ible paperboard~ or are ~ormed ~rom ~lat ~heet work folded to ~orm the u~lts~ Other patent~ disclo~e semi-rigid one~plece receptacl~s~
It i~ also known that molded fiber urinals have been made ln the past as a single molded unlt using complicRted and expenslve dles~ U~S. Patants 27115~7227 2~1Ll9~879; 2J20L~276 and 2,961~043 illustrate method~q and tooling for molding ona-piece hollow article.q with a nsGk which i~ smaller than ik3 main body~
The pre~ent inv~ntion relate~ to a dlsposabla urinal which i~ formed from m~ting upper and lower ~ections made o~
mold~d pulp material ~uGh Q~ u~ed ~or making egg ¢arton~ . ~he two section~ are ~orm~d on ~impl~ molding dies on a conventior~l molding machi~e at a relatively rapld speed, thu~ eliminatlng the above mentlon~d requirement o~ mold opanlng te remove the ~ormed urinal4 Both the upper and lower section3 have axter-nallyD laterQlly ~x~ending su~stantially continuou~ nges at ~2~

their lowermost and uppermo~t borders r~speatively. The~0 ed~e~ are adhered togeth0r preferabl~ by glue to form a unltary structu~e of the two mat~ng section~ The urinal includes a mouth~ neck and a body or liquid collecting porklon and has a shape or design similar to known urlnal~.
Advantage~ o~ the two plece urinal of th~ present inventlon over the slngle molded oontainer are ~aster moldlng speed~, less C03t per piece and ~uch less shipping and storage space are requir~d a~su~ing that the piece9 are adhere~
together near the point o~ use/ At large hospikal~ with long term p~ients such as ve~erans'~acilitle~9 the assembly o~ tha unit~ could be part o~ a work-therapy programO In a large city with many hosp~tals in a given area, ~he assembly o~ the part~
could be done by a distributor who would assemble to o~d~r, thus taking advantage of' the shippin~ and storage spa¢e ~a~ings mantioned above~

The sections 1 and 3 are o~ molded ~iber material and are ~ormed of simple molding dieS on a oonventional molding maohine at a relatively rapld speed~
To form the cornplete~ urlnal, the top and bottom sections 3 and 5 are molded ~rom ~bbr pulp materlal on a conventional molding machine a~ter which the sections are dri~d. lue~ or other adhering material i~ then applied to one or both o~ the ~langes 7 and 9 which are then pre~sed together to ~orm a ti~ht seal or ~eam between the two ~ections whereby a unitary urinal ls ~ormed~

Claims

THE EMBODIMENTS OF THE INVENTION IN WHICH AN EXCLUSIVE
PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:

1. A substantially hollow disposable urinal formed as an assembly of mating top and bottom sections, each section being molded to self-retaining shape from fibrous pulp material, flanges extending from the lowermost portion of the top section and the uppermost portion of the bottom section, each molded section being free of reverse drafts or overhangs, and means for adhering together the flanges of the top and bottom sections to form a substantially rigid non-collapsible urinal, each section being formable in simple molding dies on a conventional molding machine at rapid speed, nestable with similar sections during shipment to a desired location and assemblable for use at said desired location into a one-piece urinal by means of said adhering means.
