Description
BACKGROUND OF THE INVENTION
This invention relates to a disposable dental cleaning device and
more particularly, to a disposable dental floss unit for cleaning
between the teeth.
Interdental cleaning with floss has been a recommended dental
health care procedure. Heretofore, however, public places such as
restaurants and the like, have offered picks to their customers for
the purpose of relieving distress caused by food particles lodged
between the teeth. Picks of the type offered are generally
considered unsatisfactory, because they carry sharp points which
may pierce the gum and may otherwise snap and become lodged between
the teeth during the cleaning procedure.
Since disposable dental cleaning devices are usually offered as a
service in restaurants and the like, picks have generally been
offered rather than dental floss devices, because of the reduced
cost thereof. Accordingly, a low cost, compact, sterile dental
floss unit would satisfy customer demand for such devices and would
permit restaurants and the like to offer these devices as a service
from which they would obtain greater customer satisfaction.
SUMMARY OF THE INVENTION
Generally speaking, in accordance with the invention, a disposable
dental floss cleaning unit is constructed from a blank comprising a
panel having a score line therein defining substantially
symmetrical side walls foldable about the score line into
confronting relationship along the respective underside surfaces
thereof. The confronting underside surfaces of the respective side
walls may be fixedly connected, for instance, by application
thereto of a suitable adhesive.
An interior continuous score line within the body of the blank
defines a removable area thereof substantially symmetrical about a
plane passing through the score line. Across the removable area of
the blank, at least one length of dental floss is tautly strung
having its opposed ends fixedly connected to the blank. Upon
removal of the removable area from the blank, the dental floss is
accessible for use.
In one embodiment of the invention, the length of the dental floss
underlies the blank and is adhesively connected thereto in
substantial alignment with at least a portion of the score line. In
another embodiment of the invention, a length of dental floss
respectively overlies each side wall of the blank and opposed ends
thereof are respectively connected thereto. Each length of dental
floss is proximate and substantially parallel to the fold line of
the blank.
The device may be overwrapped with a removable sterile wrapper
until use thereof. Preferably, the device is slidable from the
wrapper for use. After the device is used for its intended purpose,
it may be disposed of.
It is, therefore, an object of the invention to provide a
disposable, low cost, compact, sterile dental floss unit for
relieving distress caused by food particles lodged between the
teeth.
It is another object of the invention to provide a mass
distributable disposable dental floss unit.
A further object of the invention is to provide a novel blank from
which a disposable dental floss unit may be fabricated.
Still other objects and advantages of the invention will, in part,
be obvious and will, in part, be apparent from the
specification.
The invention accordingly comprises the features of construction,
combinations of elements, and arrangement of parts which will be
exemplified in the constructions hereinafter set forth, and the
scope of the invention will be indicated in the claims.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings, a panel 10 is longitudinally scored
along a line 13 to define a pair of substantially symmetrical side
walls 11 and 12 therein. As best seen in FIG. 3, side walls 11 and
12 are respectively foldable about score line 13 into confronting
relationship along the respective underside surfaces thereof.
Respective underside surfaces of side walls 11 and 12 are coated
with an adhesive 16 as best seen in FIG. 2, for fixedly connecting
the confronted surfaces.
The depth of the scoring along line 13 is somewhat less than the
width of panel 10 for thereby providing a hinged connection between
side walls 11 and 12. The depth of the scoring along line 13 is,
however, substantially uniform and in the folded condition of the
panel, best seen in FIG. 3, the hinged connection is substantially
planar. Referring again to FIG. 3, the planar hinged connection is
substantially perpendicular to respective planes of side walls 11
and 12.
An interior continuous score line 14 within the body of panel 10
extends fully through the width thereof and defines a removable
contiguous area 11', 12' of respective side walls 11 and 12.
Removable area 11', 12' is substantially symmetrical about a plane
passing through score line 13. As best seen in FIGS. 4 and 7,
respective sections 11', 12' of the removable area are provided
with respective pairs of spaced recesses along the respective
peripheries thereof. Each recess is alignable with a nub extension
20, 20' defined in the continuous interior edge 22 defined in
respective side walls 11 and 12 by score line 14. Therefore, area
11', 12' is selectively removable from panel 10 by application
thereto of an outward pressure for releasing the recesses thereof
from interfitting, respective, nub extensions 20, 20' provided in
continuous edge 22.
With particular reference to the embodiment shown in FIGS. 1-4, a
single length of dental floss 15 is tautly strung across removable
area 11', 12' of panel 10. The strand of floss underlies panel 10
and the removable area thereof. Adhesive 16 coated on the underside
of panel 10 fixedly connects dental floss 15 thereto. The strand of
floss is aligned with the score line 13 and adhesively connected to
the underside of panel 10 substantially contiguously with the
hinged connection defined therein. It is a critical aspect of the
construction of the dental floss cleaning unit that adhesive is not
applied to the underside of removable area 11', 12'. In the folded
condition of the blank as best seen in FIG. 3, dental floss 15 is
adhesively secured between side walls 11 and 12 and a usable
portion thereof is overfitted by removable area 11', 12'. Upon
disengagement of area 11', 12' from panel 10, a usable portion of
dental floss 15 is visible and the removal space defined thereby
provides an access space whereby the floss portion may be suitably
inserted between teeth of a user thereof. The distance between
floss 10 and the vertex of the access space as defined by
continuous edge 22 in panel 10 is suitably determined to exceed the
length of a user's teeth to facilitate the use of the device.
Referring now to FIG. 4a which shows an alternate embodiment of a
device constructed in accordance with the invention, like numerals
designate like members as used in connection with the embodiment
heretofore described. The general construction of the blank is
substantially identical with that of the prior embodiment, except
that the removable area thereof has a somewhat different shape and
continuous edge 22' as seen upon the removal thereof defines a
substantially U-shaped access space. According to the construction
of this embodiment, two strands of dental floss 15 and 15' are
employed. Each of the strands of floss overlies a respective side
wall 11, 12 of the panel and opposed ends thereof 21, 21' are
respectively fixedly connected to the side wall as by stitching.
Each strand 15, 15' is arranged proximate the hinged connection
between side walls 11 and 12 and substantially parallel thereto. As
seen in FIG. 4a, the device is in condition for use. Prior to use,
a removable area is releasably connected in the access space
between respective strands 15, 15'. In all other details of
construction, this embodiment of the device is identical with the
embodiment heretofore described above.
The device in its unused folded condition, as best seen in FIG. 3,
may be overwrapped with a sterile wrapper as best seen with
reference to FIGS. 7-9. The wrapper may have open ends for sliding
the device therethrough and may comprise a sheath for overfitting
the device. Respective ends 18 and 18' of the sheath may be secured
in overlying-underlying relationship by application thereto of a
suitable adhesive 19.
In practice, the device may be removed from the sheath and the
removable area thereof may be releasably connected for use of the
visible portion of the dental floss. The access space provided by
releasing the connection of the removable area allows convenient
use of the device. After the device is used, it may be disposed of.
While the blank may be fabricated of a large number of suitable
materials, it is preferably fabricated of a paperboard. Any
suitable adhesive may be employed for confronting side walls of the
panel, provided it is non-toxic to a user.
It will thus be seen that the objects set forth above, among those
made apparent from the preceding description, are efficiently
attained and, since certain changes may be made in the above
constructions without departing from the spirit and scope of the
invention, it is intended that all matter contained in the above
description or shown in the accompanying drawings shall be
interpreted as illustrative and not in a limiting sense.
It is also to be understood that the following claims are intended
to cover all of the generic and specific features of the invention
herein described, and all statements of the scope of the invention
which, as a matter of language, might be said to fall
therebetween.
