DISPENSING CONTAINER OF FOLDED DISPOSABLE TOWELS
Abstract
A stack of small liquid-saturated folded disposable towels is
sealed within a disposable container under a cover sheet, which
protects and preserves the contents during storage prior to use.
When the cover sheet is stripped from the peripheral flange to
which it is attached, by grasping a loose tip over a depressed
corner of the flange, it exposes a removable lid having a pair of
opposite edges flexibly inserted under overhanging projections on a
framing ridge on a dished panel, which is secured to a shelf within
the rim of the receptacle. Towels are dispensed through a lobular
cross-shaped aperture in the center of the dished panel, which is
surrounded by a flat margin joined by sloped walls to a ledge under
the framing ridge, which provides a supporting surface for the
edges of the lid. The sides of the container are concavely indented
and vertically ridged to stiffen and decorate them. The bottom is
also inwardly dished for the same purposes.

Description
BACKGROUND OF THE INVENTION
This invention relates to a disposable sealed container for
dispensing disposable folded treated towels. Most disposable
containers for dispensing disposable folded tissues or towels are
made of thin paperboard or cardboard and are not suitable for
containing liquids or odors used to saturate cleansing towels, or
are not readily reclosable (U.S. Pat. No. 2,990,948). Such towels
are commonly sealed individually within foil packages or envelopes
such as described in U.S. Pat. No. 3,057,467, or may be packaged in
bulk in a plastic jug or in an impervious wrapper as described in
U.S. Pat. No. 3,325,003. These existing packages are either
relatively expensive in material and in assembly and loading costs
or not as convenient to store and use as might be desired. An
object of this invention is therefore to provide a relatively
simple and economical disposable container for retaining and
dispensing treated folded disposable towels, and it more
particularly relates to such a container which is easy to fill,
load and seal by automatic machinery and which can be conveniently
reclosed.
SUMMARY
In accordance with this invention a stack of folded towels is
contained within a receptacle of a thin moldable sheet material
under an apertured panel which retains the towels for convenient
dispensing through the aperture. The towels may be saturated with a
solvent liquid to enhance their cleansing properties and they are
conveniently loaded into the receptacle before the panel is secured
within the rim of the receptacle. A framing ridge having
overhanging projections retains a removable lid over the aperture
for removably closing the receptacle after a cover sheet is
stripped from a peripheral surface of the receptacle, which is
conveniently provided by a flange. The panel may have an inwardly
dished central area joined to the framing ridge by a peripheral
ledge which provides a supporting surface under the edge of the
lid. Indentations near the edges of the lid may provide convenient
grips for flexing the lid to facilitate removal and engagement. The
cover sheet seals the contents during storage; and after it is
stripped, the lid provides convenient access to the towels and
closure between uses. A corner of the flange may be downwardly
stepped to facilitate grasping and stripping of the seal sheet. A
substantially wide lobular cruciform aperture helps spread the
towel being grasped and confine those under it.

DESCRIPTION OF THE PREFERRED EMBODIMENT
In FIGS. 1 and 2 is shown a sealed container 10 for dispensing a
stack of folded towels 12 including a receptacle 14 of a thin
moldable sheet material such as thin opaque polystyrene. A sheet of
white polystyrene 0.030 inch thick is a suitable material.
Receptacle 14 is for example rectangular or square in plan
cross-section and it includes concavely indented side walls 16 and
an upwardly dished bottom wall 18 joined by rounded bottom corner
edges 20. Side walls 16 are stiffened and ornamented by a series of
vertical protrusions or ridges 22.
Receptacle 14 also includes a peripheral shelf 24, following the
curve of and disposed upon the rim of side walls 16 upon which an
apertured panel 26 for retaining towels 12 is lodged in a manner
later described in detail. Flange 28 attached to the rim of shelf
26 provides a surface to which cover sheet 30, for example of
laminated foil and paper is sealed to preserve the contents during
storage. These contents advantageously include a liquid solvent
which saturates towels 12 to enhance their cleaning properties.
Cover sheet 30 accordingly preserves the liquid solvent and
prevents odors from escaping during storage. The tip edge 34 of one
corner of flange 28 is downwardly stepped to facilitate peeling and
stripping of the unattached corner 32 of cover sheet 30 as shown in
FIG. 2. Tip edge 34 forms a step having a tip surface disposed
below the level of flange 28 which prevents the portion of cover
sheet 30 disposed above it from being adhered to it when the main
portion of sheet 30 is sealed to flange 28. This automatically
maintains the tip portion of cover sheet 30 free of tip surface 34
to facilitate grasping it.
Stripping of cover sheet 30 from receptacle 14 exposes inner lid 36
engaged under a pair of opposite overhanging projections 38 on
framing ridge 40 in panel 42 lodged on shelf 24 of receptacle 14.
Lid 36 is conveniently flexed for removal in the direction of arrow
44 shown in FIG. 4 and also for reinsertion by gripping tapered
indentations 46 in the tips of opposite fingers 48 and 50. Edges 52
of lid 36 are accordingly removed and reinserted back into spaces
54 between overhanging projections 38 and ledge 56 joining dished
apertured central area 58 of panel 26 with ledge 56. The opposite
sides of framing ridge 40 are straight and unobstructed and the
width of lid 36 parallel to the length of indentations 46 is
narrower than the length across them to permit lid 36 to freely
rest on ledge 56 when turned 90.degree. from the position shown in
FIG. 3.
Dished central area 58 includes flat margin 60 with lobular cross
shaped (or cruciform) aperture 62 and sloped side walls 64.
Aperture 62 in the form of a cross with an open center and
generously rounded inner corners 63 and outer corner 65 helps
confine underlying towels within receptacle 14 as the top towel is
being removed and unfolded.
Panel 26 does not interfere with rapid and convenient loading of
towels 12 and their saturated solvent into receptacle 14 because it
is not installed until after loading. Its edge 25 is positioned
upon shelf 24 by automatic machinery and secured to it, for example
by sonic welding. The substantial area of shelf 24 engaging the
edges of panel 26 dependably locates panel 26 in position without
danger of its being forced too far into receptacle 14 during
automatic assembly. Lid 36 may be conveniently engaged with panel
26 either before or after installation of panel 26. The entire
contents including panel 26 and lid 36 are sealed by cover sheet
30, which preserves the contents during storage.
After cover sheet 30 is stripped by grasping free corner 32 over
step 34, lid 36 provides a convenient closure for the contents; and
it is conveniently removed and inserted back over aperture 62. The
rectangular shape facilitates loose covering in one position in
which it clears projections 38 and removable locking when its
longer length is inserted under projections 38. Removal of towels
12 is facilitated by folding and connecting in any convenient
manner, such as interlocking or spot connection, or they merely may
be stacked and separately grasped.
