PATENYEU M028 m SHEET 1 [IF 2 FIG INEN OR: HAROLD w, LONG ATTYS PATENTE-Dmczsrsn $629573 SHEET 2 OF 2 FIG] ATTYS CONTAINER STRUCTURE The present invention relates to containers which are particularly adapted for use in collecting specimens of human waste and for containing the specimens to enable them to be transported without spillage.

At present, specimens of urine are collected for urinalysis purposes in hospitals, laboratories and doctors offices. In serving large numbers of patients, it is not uncommon for laboratory personnel to collect a correspondingly large number of urine specimens per day. At present, open-top paper cups, beakers, or other containers, are customarily used for this purpose. Depending on the laboratory staffing, it is possible that many specimens may not receive immediate processing and, unless adequately covered, the specimens tend to emit an unpleasant odor. Also, it is to be noted that the aforementioned types of containers may readily spill their contents if accidentally bumped or if jostled during their transportation in and about hospital and laboratory facilities.

Specimen collectors have been proposed having openings which are shaped to engage against the female anatomy for use by females in collecting specimens. Examples of collectors of this type are disclosed in US. Pat. Nos. 3,329,973; 3,473,172; and 2,734,198. None of these patents, however, discloses a collector having a removable lid. Thus, even if these collectors were employed to contain specimens for urinalysis purposes, their lack of suitable cover means may cause unpleasant, if not unsanitary, laboratory conditions.

A covered receptacle for collecting and containing a urine specimen is disclosed in US. Pat. No. 3,l72,l30; however, this type of collector does not provide all the advantages of the shaped opening and the closure is not sealed. The cover is hinged to the collector, and, in order for the specimen to be withdrawn from the receptacle, the lid must be raised by laboratory personnel. Not only does the removal of the cover increase the possibility of spilling the contents, but it also increases the possibility of contamination of the specimen or of the personnel by disease germs around the receptacle openmg.

With the foregoing in mind, it is a primary object of the present invention to provide an improved container for collecting a specimen of urine from a human female and containing the specimen in a manner which prevents the escape of odors therefrom and which enables the specimen to be transported without spillage.

It is a further object of the present invention to provide a feminine urine specimen collector having a contoured opening with a unique lid which provides both a sanitary closure for the collector, and the possibility for stacking the covered containers one upon the other.

As a still further object, the present invention provides a novel removable lid for a specimen collector which provides a sealed closure for the collector but which may be punctured to permit a portion of the specimen to be withdrawn by a pipette without the necessity of removing the lid.

It is a further object of the present invention to provide a new fluid container having a frangible lid with a shaped pour spout which permits contents of the container to be poured therefrom without prior removal of the lid.

More specifically, the present invention provides a container having a body having an upstanding sidewall with a shaped terminus which is adapted to engage the female pubic region and receive the labial portion of the genitalia within its opening. A removable lid is provided for closing the opening, the lid being telescopically received in the container opening and having a peripheral flange which is shaped to engage over the sidewall terminus. Sealing means is provided on the inner periphery of the lid to prevent the escape of odors from the container when the lid is in position. In one embodiment, the lid is formed of frangible material and has a downwardly concave recess forming a thin wall section which is readily punctured by means of a pipette to permit withdrawal of a specimen contained therein. In another embodiment, the frangible lid is provided with a pair of downwardly concave recesses forming pierceable thin wallsections, and a pour spout is provided adjacent one of the thin wall sections to enable the specimen to be poured from the container without prior removal of the lid. The lid also has in its top side a central upwardly opening recess with a flat bottom to permit a series of the containers to be stacked vertically.

These and other objects, features and advantages of the present invention should become apparent from the following description when taken in conjunction with the accompanying drawings in which:

FIG. 1 is a side elevational view of the body of a container embodying the present invention with a portion broken away, and showing in broken lines a fragment of a lid engaged thereon;

FIG. 2 is a rear elevational view of the container body of FIG. 1 having another portion broken away;

FIG. 3 is a side elevational view of the removable lid adapted to be mounted on the container body of FIG. 1 and having a portion broken away;

FIG. 4 is a rear elevational view of the lid of FIG. 3 and having another portion broken away;

FIG. 5 is a plan view of the container of FIG. 1;

FIG. 6 is a fragmentary, longitudinal sectional view illustrating the container of the present invention with its lid in position and illustrating the bottom of a like container stacked on the lid;

FIGS. 7 and 8 are elevational views, similar to FIGS. 1 and 2, of a modified container body embodying the present invention;

FIGS. 9 and 10 are elevational views, similar to FIGS. 3 and 4, of a modified lid for use with the container bodies illustrated in FIGS. 7 and 8; and

FIG. I] is a plan view of the modified container body of FIGS. 7-10.

Referring now to the drawings, there is illustrated in FIGS. 1-6 a container body 11 for collecting a urine specimen and a lid 12 for covering the open end of the container body. As may be seen in FIGS. 1 and 5, the container body 11 has a flat elliptical bottom 13 surrounded by an upstanding sidewall 14 which is integral therewith. In the present instance the sidewall is continuously arcuate, and the upper end of the sidewall 14 terminates in an upwardly concave curvilinear edge or terminus 15 which is rounded and shaped to engage female pubic region intermediate its anterior end 16 and its posterior end 17. The container body 11, and hence its edge 15, is sized to receive the labial portion of female genitalia when the edge 15 is engaged against the female anatomy laterally of the labial folds. However, in order to enable the width of the opening to be varied, depending upon the userss anatomy, the oval outline of the sidewall 14 is resiliently flexible inwardly and outwardly adjacent the opening. Thus, the user may vary the dimensions of the container opening by applying inward pressure on opposite sides of the sidewall 14.

In accordance with the present invention, the lid is mounted on the open end of the container body 11, as illustrated in FIG. 6, for effecting a sanitary closure thereacross. As may be seen in FIGS. 3 and 4, the lid 12 is of one-piece molded construction, having a plug portion 19 comprising a bottom wall 20 surrounded by an upstanding sidewall portion 21 which tapers upwardly and outwardly and which matingly engages the like-shaped tapered sidewall 14 of the container 11. The plug portion 19 is telescopically received in the open end of the container body, and in order to provide a sanitary closure, the lid 12 has a peripheral flange 25 which engages over the edge 15. In the present instance, the flange 25 extends outwardly from the tapered wall portion 21 and has a downwardly concave, rounded peripheral recess 21a shaped to mate with the edge 15. Thus, when the lid is positioned on the receptacle as illustrated in FIG. 6, the edge 15 of the container 11 is completely covered. As a result, it is impossible for the edge 15 to be contacted, for example, by the hands of a laboratory technician. Also,.it is to be noted that the posterior end 27 of the lid 12 which engages the corresponding end 17 of the container, 11 forms a smooth upward continuationof the outer surface of the container sidewall 14, extending upwardly to an elevation substantially equal to its anterior end 26. With this structure, a technician may disengage the lid 12 from the container 11 by displacing the posterior end 27 of the lid 12 in an upward direction.

As noted heretofore, there is a tendency for urine specimens in uncovered containers to emit unpleasant odors. This undesirable and possibly unsanitary condition is eliminated by the present invention which provides sealing means between the container 11 and lid 12 to thereby prevent odors from being emitted. To this end, a groove 30 (FIG. 1) is provided on the inside of the sidewall 14 of the container 11 adjacent its opening, and a head 31 (FIG. 3) is provided on the outside of the wall 21 of the lid 12 for mating in the groove 30. in the present instance, the container 11 and the lid 12 are formed of resilient materials. Thus, the bead 31 being somewhat resilient permits the lid 12 to be displaced downwardly into the open end of the container 11 until the head 31 engages in the groove 30 and thereby effects an interlock between the container 11 and its lid 12. With this structure, a secure and odortight connection is provided between the container and its lid, and the connection is sufficiently secure to prevent inadvertent disengagement of the lid from the container and spillage of its contents, for example, should the container be knocked over or jostled while being transported.

In accordance with another object of the present invention, the lid 12 is constructed to permit withdrawal of the specimen from the container body without its prior removal. For this purpose, the wall portion 20 of the lid 12 has downwardly concave recess 35 forming a thin wall section 36 centrally of the lid 12. In addition, the lid 12, and the container body 11, is preferably formed of polymeric frangible material, for example polyurethane or polystyrene. Thus, a laboratory technician may withdraw a portion of the specimen in the container by displacing a pipette downwardly to pierce through the wall section 36 and thereafter manipulate the pipette in the customary manner.

In order to enable the receptacles to be stacked vertically, the wall portion 20 of the lid 12 is spaced downwardly from the flange 25 around the rim of the lid to form an upwardly open depression or recess 45 for receiving the bottom portion of an identical container. As may be seen in FIG. 6, the recess 45 is larger than the container bottom 13, and the flat top surface of the wall 20 extends substantially parallel to the bottom 13 of the container 11, so that it is horizontal when the container is resting on a horizontal surface. Although the central section of the lid 12 is weakened by the recess 45, a thickened section 28 adjacent the inside of the container sidewall 14 provides additional material which is resistant to downward shear stresses applied on the lid 12 when a series of filled containers are stacked thereon.

in a modified embodiment of the present invention, a container (FIGS. 7 to 11) is provided which permits a small sample of the specimen to be withdrawn by means of a pipette, and which permits a larger sample of the specimen to be poured therefrom when such sample is desired. To this end, the container body 111 is like the container body 11, except for the thickened upper portion of the sidewall around the opening which protrudes outwardly from the plane of the sidewall to reinforce the container in the zone of the opening and to provide a handgrip in addition to a larger body-engaging edge 115. Like the aforementioned embodiment, the container 111 is provided with a lid 112 having a plug portion 119 with a plurality, in the present instance two, downwardly

concave recesses

135, 135 on its underside, forming a like number of frangible

thin wall sections

136, 136 spaced apart in the transverse wall portion 120. On the upper side, the locations of the

sections

136, 136 are identified by suitable indicia, in the present case indentations 137, 137 in the flat wall 120. The posterior end of the lid 112 is provided with a channel 150 formed by converging walls [500 and 15% extending upwardly from the top surface of the wall portion 120 and terminating in a notch 151. With this structure, a large volumetric portion of the specimen may be poured from the container 111 without prior removal of the lid 112 after both

wall sections

136, 136 have been punctured and the container is tipped rearwardly. If desired, however, a smaller volumetric portion of the specimen may be withdrawn from the container 111 when a pipette is displaced downwardly through one or the other of the weakened wall sections and is manipulated in the usual manner. As in the first-mentioned embodiment, the modified container 111 has sealing means which, in the present instance, comprises a series of three resilient

peripheral beads

131, 131 engaging in a like number of

grooves

130, 130 in the inside of the container sidewall 114 adjacent its opening. In addition, the underside of the peripheral flange 125 on the lid 112 is recessed to engage around the upper edge 115 of the sidewall of the container. Thus, a secure and odorproof container closure is provided.

It is to be noted that the enlarged shoulder forming the handgrip and illustrated in the modified embodiment may, if desired, be provided on the embodiments of the container body illustrated in FIGS. l-2; or, the series of sealing beads and grooves on the modified embodiment may be provided on the FIGS. 1-2 container body embodiments. Conversely, the modified embodiment may be provided with the thinner shoulder or the single sealing bead and groove of the FIGS. 1-2 container body embodiment. Thus, one or more of the aforementioned structural features may be interchanged without departing from the present invention.

In view of the foregoing, it should be apparent that a novel container has now been provided for collecting and containing specimens of female urine in a manner which limits the possibility of contamination, which is sanitary and which prevents the emission of unpleasant odors and possibility of spillage during transportation.

While many materials may be used to form the container body and lid, it is preferred to use a foamed urethane or polystyrene composition which can be molded to desired form, is resistant to the chemical action of the specimen, and yet is lightweight and sufficiently resilient and flexible to provide a tight seal and to conform to the pubic region of the anatomy. Although the container disclosed herein is particularly suited for collecting and containing specimens of human female urine, it may also be used to coliect other types of human excretions including feces and sputum and contain such specimens in a sanitary manner.

While preferred embodiments of the present invention have been described in detail, various modifications, alterations or changes may be made without departing from the spirit and scope of the present invention as defined in the appended claims.
