ORAL APPLICATOR
Abstract
Apparatus for the oral application of medicinal compositions,
fluorine compounds, dentifrice and the like includes a handle to
which a spongy block of porous material is removably, but
tenaciously, secured by a plurality of small, hooklike members
carried by said handle and interengageable with and into
reticulations on a surface of said block. The applicator is
particularly useful in applying fluorides in viscous gellike form
to the teeth.

Claims
What I claim is:
1. An oral applicator, comprising:
an elongate handle member having a proximate end adapted to be
manually grasped and a distal end introducible into the mouth;
a right rectangular spongy block of reticulated polyurethane foam
material having at least one exposed reticulated surface;
said distal end of the handle member having a broad flat surface
provided with a pile patch, substantially coextensive with said
reticulated surface, comprising a multitude of small, flexible hook
members outstanding thereon, said hook members being randomly
arranged in said patch and interengageable with reticulations in
said block at said surface when said block and said reticulated
surface are pressed together;
the interengagement of said hook members with said spongy block
surface being such that when said spongy body is mounted on said
handle to form an assembled applicator, said members will
tenaciously grip said block in such manner as to withstand sheer
forces normally encountered in oral therapeutic applications, but
also in such manner that said block may be easily peeled from said
handle by a lifting force initially applied at the end of said
block.
Description
SUMMARY OF THE INVENTION
On a broad surface at the distal end of a handle member is provided
a plurality of small, outstanding hooklike members either
integrally formed or separately formed as part of a patch that is
secured to the handle in a suitable manner. A spongy block of
cellular, porous material capable of absorbing and otherwise
receiving medicinal compositions, fluorine compounds, dentifrice
and the like is provided for attachment to the handle by being
engaged by said hooklike members primarily by pressing the block
and handle together. Immersing and pressing the block as carried by
the handle onto or into a body of the composition to be applied
results in the same in part entering into pores of said body
whereby it may be transferred and applied to dental or other
surfaces in an oral cavity. The block is tenaciously held to said
handle during normal use but may be easily peeled therefrom when
disposal following use is intended.

FIG. 1 is an exploded perspective view of an oral applicatOr;
FIG. 2 is a cross section of the distal end of the applicator as
assembled;
FIG. 3 is a side view of an alternate form of the oral
applicator;
FIG. 4 shows an alternate form of applicator block; and
FIG. 5 shows alternate block attaching means for an applicator.
DESCRIPTION
Elongate handle member 10 has a proximate end 12 adapted to be
manually grasped and a distal end 14 to receive and carry
applicator block 16.
Block 16 is preferably spongy and formed of cellular porous
material such as flexible plastic foam, sponge rubber and the like.
It is desirable and preferred to employ polyurethane foam material
cut and shaped to form a right rectangular block. At least one
surface 18 of block 16, i.e. that to be juxtaposed to the broad
surface 20 of distal end 14 of the handle 10, is reticulated and
netlike or weblike.
In the preferred embodiment of the invention a plurality of small,
hooklike members 22 is provided. Members 22 outstand in the form of
a pile generally extending over an area substantially coextensive
with the area of reticulated surface 18.
When block 16 and distal end 14 are pressed together, hook-like
members 22 interengage with reticulations on surface 18 to
tenaciously secure the block and handle together. This
interengagement is easily obtained by direct pressure due in part
to the hooklike members entering into cavities on the reticulated
surface 18 and snagging themselves in the material forming the
walls thereof.
A preferred means providing the plurality of hooks 22 is derived
from a well-known two-part system marketed under the trademark
"Velcro". In this system one part comprises a woven or molded
flexible panel having a pile surface formed of cut loops and the
other part has a pile surface of uncut loops. When pressed
together, the two parts join. Employed herein is a patch 26 of
cut-loop pile, the latter providing a plurality of hooklike
members. Patch 26 is secured adhesively or by other bonding means
to distal end 14. Such hooklike members 22 readily interengage in a
tenacious manner in the reticulations of block 16 as described and
the assembly is such that the parts may not separate under forces
normally encountered in oral therapeutic applications. However,
when an application is concluded, and it is intended to disassemble
the applicator, the block 16 may be easily removed by being peeled
from the handle.
Referring to FIG. 2, block 16 will be seen mounted on handle 10.
The mounting means comprise a plurality of small, hooklike members
22 outstanding on the surface of a woven backing patch 28 secured
to the distal end 14 of handle 10. Patch 28 may desirably be
secured to the handle by adhesive means interposed between the back
of the patch and a broad face 20 of handle 10.
In FIG. 3 handle 10 has the proximate end 12 and the distal end 14
connected by an offsetting or angled portion 15 therebetween. With
this arrangement not only may a person reach over the edge down and
into a container to engage and assemble the applicator, but also it
will be found that there is increased springiness to the handle
occasionally desirable during oral applications. As seen in FIG. 3,
the hook members are randomly arranged.
In FIG. 4 the alternate form of pad or block 36 has surface 38 for
engagement by the hook-like means 22 and its opposite working
surface toothed to facilitate penetration into interproximal spaces
between a person's teeth.
A distal portion 42 of handle 10 is shown in FIG. 5 as having hooks
integrally mounted therein. In such case a cellular block, either
16 or 38, when pressed thereto will be tenaciously gripped during
use and may easily be peeled therefrom for disposal.
