Description
BACKGROUND, SUMMARY AND OBJECTS OF INVENTION
U.S. Pat. Nos. 3,579,652; 3,228,444 and 3,164,186 disclose specimen
collectors for collecting urine samples. Such patents have funnel
portions leading to the container. These funnel portions either
have rigid collars or are too rigid to conform to the shape of the
body or else are made from a sheet-like plastic material which is
extremely flexible and difficult to hold in conformance with the
body.
While such types of specimen collectors are in use, where the
funnel is relatively rigid, besides being difficult to conform it
to the body, such collectors cannot be stored in small places.
Where the funnels are flexible and collapse to extend about the
specimen container, such funnels do not protect the mouth of the
container from contamination and must usually be provided with
covers which renders it difficult for the large end of the funnel
to be readily conformed to the shape of the body.
In accordance with the principles of the present invention, we
provide a specimen collector having a funnel detachably connected
to the mouth of the collector and completely protecting the mouth
of the collector from contaminants. We further provide a specimen
collector having a collapsible funnel attached to the container, in
which the funnel has sufficient rigidity to efficiently serve as a
funnel, but is soft enough to conform to the GU area to facilitate
the collection of a specimen in midstream.
An advantage in the invention is that the funnel is large enough to
lend to the ease and efficiency in the collection of a specimen of
urine, but is collapsible to allow the specimen bottle to move up
inside the funnel.
A still further advantage of the invention is that a coupling
member couples the funnel to the inside of the container, with the
coupling member and the portion of the funnel extending thereabout,
extending about the lip of the container, in which a simplified
form of bayonet-type locking means is provided to readily couple
the coupling member and funnel to the mouth of the container, or to
remove the coupling member and funnel therefrom, where it may be
desired to cover the container by a cap.
Other objects, features and advantages of the invention will be
readily apparent from the following description of a preferred
embodiment thereof, taken in conjunction with the accompanying
drawings, although variations and modifications may be effected
without departing from the spirit and scope of the novel concepts
of the disclosure.
DESCRIPTION OF THE DRAWINGS

the container.
DESCRIPTION OF PREFERRED EMBODIMENT OF INVENTION
In the embodiment of the invention illustrated in the drawings, we
have shown a generally frusto-conical specimen bottle 11, which may
be made from a rigid plastic material or from glass and has a
relatively flat bottom 12, a top generally cylindrical mouth 13 and
an integral frustoconical side wall 14.
As shown in FIGS. 1 and 4, the mouth 13 has threads 15 extending
along the outer side thereof, to accommodate closing of the
specimen bottle by a cap or other closure member (not shown). The
upper end of the mouth 13 defines a lip 16. Inwardly extending
diametrically spaced ribs 17 extend inwardly of the mouth 13,
adjacent the lower end thereof, and are adapted to engage within an
outwardly opening annular groove 20 extending about a coupling
member 21, provided to couple a funnel 23 to the mouth of the
specimen bottle.
The coupling member 21 is shown as having a neck 24 of the funnel
23 extending thereabout and downwardly therealong to the annular
groove 20. The upper end portion of the coupling member 21 is
flanged in a radial outward direction, as indicated by reference
numeral 25 (FIG. 4), to extend over the lip of the neck of the
bottle and to retain the neck 24 of the funnel 23 into engagement
with said lip, to hold contaminants from said lip. The coupling
member 21 has diametrically opposed flattened portions 26
corresponding to the flattened ribs 17 and registering with said
ribs when inserting the funnel in the neck of the bottle.
When it is desired to insert the funnel in the neck of the bottle,
which is usually done prior to packing and shipment, the flattened
portions 26 of the coupler 21 are registered with the ribs 17 to
accommodate the coupler 21 and neck of the funnel to be pushed
downwardly along the mouth of the bottle, until the ribs 17
register with the annular groove 20. The coupler and funnel may
then be turned a quarter of a turn, to fasten the coupler and
funnel to the mouth of the bottle, with the flattened ribs in
engagement with the annular recessed portion 20 of the coupler.
This in effect forms a bayonet-type of joint, detachably connecting
the funnel to the mouth of the specimen bottle 11.
Referring now in particular to the details of construction of the
funnel, the funnel may be made from a relatively inexpensive
plastic material such as a low density polyethylene which is
sufficiently rigid to stand by itself in a funnel shape, but is
sufficiently flexible to be distorted by the fingers to properly
fit the shape of the patient.
As shown in FIGS. 1 and 2, the funnel 23 fits about the outside of
the coupling member 21 and is engaged thereby with the lip 16 of
the mouth of the specimen container, and includes a lower generally
frustoconical funnel portion 27 extending upwardly from the neck 24
and an axially aligned larger diameter upper frusto-conical portion
29 connected to said lower portion by an integral annular shoulder
30. The larger diameter frusto-conical portion 29 of the funnel
terminates into a generally cylindrical wall 31 having an annular
rim 32 extending radially from its upper side, and having a tab 33
formed integrally therewith and extending outwardly therefrom, to
afford a means to be readily grasped by the fingers to extend the
funnel from the collapsed position shown in FIG. 3 to the extended
position shown in FIG. 1, when it is desired to collect a specimen
of urine. The tab 33 may also be grasped to hold the rim 32 in
contact with the body.
As has previously been mentioned, the funnel is usually supplied in
the collapsed condition shown in FIG. 3 to reduce the space taken
up by the collector during shipment and storage. When, however, it
is desired to use the collector to take a specimen, it is merely
necessary to grasp the tab 33 by the fingers of one hand and extend
the funnel to the position shown in FIG. 1, which as shown in this
Figure, is substantially twice the height of the collector when in
a collapsed condition. If, for any reason, the funnel has been
extended and the collector has not been put in use and it is
desired to send the collector back to storage, the funnel may be
collapsed upon itself about the shoulder 30 in such a manner that
the vertical height of the specimen collector is cut in half, with
the larger diameter portion 29 of the funnel extending outside of
the smaller diameter portion 27 thereof with the smaller diameter
portion inverted relative to the larger diameter portion.
It may be seen from the foregoing that a new and improved form of
collector for specimens of urine has been provided which is
efficient and comfortable for use by the patient, of a rugged
detachable construction, compact for storage and avoiding
contaminating the lip of the specimen bottle before, during and
after the taking of a specimen.
