Description
Although this vessel and closure can be employed for the
hydraulically agitated cleaning of various types of articles, it is
dentures which are particularly adapted to be cleaned therein.
There are of course various special preparations in which dentures
can be soaked, but there is in fact no better method than to wash
them regularly in scalding water. Consequently, an assurance of
avoiding obnoxious odors and in order to promote good hygiene,
persons wearing dentures diligently wash them in hot water, with or
without cleansers, and in steaming and/or scalding water if at all
possible. However, there is a limit to the degree of heat which a
person's hands and fingers can withstand while manipulating the
dentures in the hot water, and this presents a serious limitation
in the results of such a washing operation. Open-topped vessels and
glasses or jars are not the answer, since an unconfined hydraulic
wash will flood the dentures out of a vessel, glasses are fragile,
and uncontrolled hydraulics cannot be most effective. Therefore, it
is na object of this invention to provide a vessel and closure
combination that most effectively controls hydraulic flow, to
direct its entry into and to direct its discharge from the vessel
while creating and confining the turbulent flow of fluid and
agitation of the denture and/or articles within the confines of
said vessel.
It is also an object of this invention to provide a vessel, closed
as above referred to, which has holding means that captures it in
working position for receiving a pressurized jet of water, all
without capsizing and without requiring a person to hold the vessel
in position. With the present invention, the vessel and its closure
are aligned with the jet of hot and/or scalding water eminating
from a faucet, and left there, preferably within the confines of a
washbasin or the like, to receive the jet of water and to redirect
the water so as to create the agitating action sought for, and all
to the end that the dentures float about and are thoroughly washed
from every single angle reaching into every crevice and
interstice.
The various objects and features of this invention will be fully
understood from the following detailed description of the typical
preferred form and application thereof, throughout which
description reference is made to the accompanying drawings, in
which:
FIG. 1 is a sectional view taken through a typical sink, showing
the articles of the present invention in use and in elevation;
FIG. 2 is an enlarged sectional view of the assembled structure of
the present invention as it is shown in FIG. 1;
FIG. 3 is a plan view taken as indicated by line 3-3 on FIG. 1;
and
FIG. 4 is a fragmentary sectional view taken as indicated by line
4-4 on FIG. 2.
Dentures, partial or full, are characterized by their sets of teeth
fixed in a frame adapted to fit with a person's jaw through
engagement of the gums, and/or with remaining natural teeth. During
the course of a day's use, the fluids of the mouth and
accumulations of food particles are caught up in the crevices and
interstices of the dentures and become odorous. Therefore,
periodical cleaning of such dentures is necessary and among the
best methods of cleaning is washing with scalding water. Various
preparations can be used before and/or after such a washing, but in
any case use of very hot water is most effective and especially
when agitation thereof is employed. Consequently, the present
invention provides a vessel V and a closure C for hydraulic
agitation of dentures D and the like, wherein a jet of very hot
water can be usefully employed in the form that it is usually
delivered from a water faucet F. As shown, a jet of water 10 is
delivered in a substantially vertical and downward direction from
the faucet F in a pencillike stream. Such a jet of water 10 is
common and almost universally employed in connection with domestic
washbasins B in lavatories and the like. Such basins are usually
provided with porcelain interiors or the equivalent and with a
smooth hard-surfaced bowl. A drain 11 is provided at the bottom for
carrying away used water.
In accordance with the invention a vessel V and closure C
combination is provided and usefully employed by aligning it with
the jet of water 10 and with the dentures D or the like
accommodated therein for agitation and cleansing by a washing
action that is most effective. The vessel V and closure C are made
of moldable material such as a plastic that impedes heat transfer.
There are many such plastics which are easily molded and which do
not efficiently transfer heat, which are also durable and conducive
to cleanliness. It is such material that the vessel V and closure C
are made of, preferably a plastic that is bendable for manipulating
the two elements V and C into and out of coupled engagement.
The vessel V is an upstanding open-topped vessel having a bottom 15
and sidewalls 16. The bottom is horizontally disposed while the
walls 16 are vertically disposed extending upward from the outer
periphery of the bottom. As shown, the bottom is round in which
case the walls 16 form a cylinder. The upper end of the vessel is
completely open and has an attaching rim 17 which in practice is a
radially enlarged bead 18. Also, in carrying out the invention, the
bottom 15 is filleted at 19 where it joins the walls 16, and said
fillet turns radially inward and into a cone-shaped center 20 that
projects convexly upward establishing a concaved bottom.
The closure C is a planar element that covers the open upper end of
the vessel V and is preferably a domed disc form having a periphery
with a depending flange 22 to mate with the bead 18 for attachment.
The said bead 18 and flange 22 have overlapped engagement that is
forcibly fitted for coupled engagement of the closure C and
supporting vessel V. In accordance with the invention, the closure
C is apertured at 30 and 35 for the separated reception and
discharge of fluid, and nozzle means 40 is associated with the
receptive aperture 30 and directs fluid to swirl through the vessel
V in a predetermined manner. In practice, a flow pattern is
established whereby the entry of high-velocity fluid swirls
downwardly in a helical path adjacent the cylindrical wall 16 and
is turned at the bottom of the vessel to swirl upwardly in a
continuing helical path at the center of the vessel and is then
discharged. The flow is continuous and impeded by the presence of
articles within the vessel, and all of which creates turbulence and
assures effective cleaning, with the apertures 30 and 35 positioned
and shown as now described:
Aperture 30 is the fluid-receiving port and it is located in the
marginal portion of the closure C immediately adjacent the wall 16
of the vessel. Aperture 35 is the fluid-discharging port and it is
located in and occupies the central portion of the closure C. Both
apertures 30 and 35 are ports of ample area, the aperture 30 being
of somewhat larger area than the diameter of the jet of water 10.
This is, the jet of water 10 enters the aperture 30 with clearance.
However, the lower velocity water leaving the vessel V is in a
flooded condition and simply swirls upwardly through the aperture
35 to flow laterally in omnidirections.
A feature of the invention is the nozzle means 40 which determines
and directs the predetermined flow pattern of the fluid that is
forced into the vessel V and is spent therein and then discharged
for disposal as waste. The nozzle means 40 is adapted to receive a
high-velocity jet of water 10, to collect it and to redirect it to
the useful purpose of agitation within the vessel V. Normally, a
jet of water 10 is disposed vertically or substantially so, and its
velocity is downward. Therefore, the nozzle means 40 opens upwardly
for the reception of the jet water 10 and is an upwardly flared
cone that has a funnel shape and a corresponding collective
function. However, the axis a of the cone-shaped nozzle means 40 is
angularly or helically disposed and tangent to a radius point
spaced immediately inward from the wall 16 of the vessel V.
Although the pitch of the helix can vary, a 45.degree. angle is
most practical and is shown. The opening 41 of said nozzle means is
restricted as compared with the mouth 42 of the aperture 30 and
functions to direct fluid circumferentially within the confines of
the cylindrical wall 16. Consequently, the jet of water 10 revolves
and/or swirls toward the bottom of the vessel where it is turned
radially inward by the fillet at 19 and upwardly by the conical
center 20, whereupon the vessel V is filled with swirling water
that rises to the top and discharges through the central aperture
40 and without interferring with the incoming jet of water 10.
Securement means B is provided for the attachment of the vessel V
to the smooth surface of a porcelain bowl or the like, and as shown
in the drawing, the means B advantageously employs the bottom
concaved contour of the vessel V. In the event that the plastic
material of the vessel is sufficiently pliable or supple then the
perimeter of the bottom 15 is feather edged as indicated at 25, and
so that its suppleness conforms to the contours of the basin. In
the event that the vessel material is excessively stiff, then the
securement means B is a separate element of sufficiently pliable
material, such as an elastomer, attached to the bottom 15 and with
the lip 25 projecting radially and downwardly at its perimeter, as
shown.
When in operation as hereinabove described, the dentures D are
captured within the confines of the vessel V and its attached
closure C, the dentures being a greater bulk than that permitted to
pass through the aperture 40. The rolling effect of the downwardly
swirling water at the periphery acting in opposition to the
upwardly swirling water at the center lifts and tumbles the
dentures, and a continuation of this effect ensures a thorough
cleaning, especially when jetting high-velocity scalding water into
the vessel as directed by the nozzle means 40. Upon completion of
sufficient cleaning, the plastic vessel V is manipulatable, due to
the low heat-retaining character of the plastic material, and
without danger of scalding one's hands or fingers. It is to be
understood that the vessel V and fluid directive closure C therefor
is applicable to a wide range of sizes and configurations, namely
to conduct cleaning processes and the like as may be required of
articles susceptible to processing by agitation in a moving
fluid.
Having described only a typical preferred form and application of
my invention, I do not wish to be limited or restricted to the
specific details herein set forth, but wish to reserve to myself
any modifications or variations that may appear to those skilled in
the art.
