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.
14 Claims, 6 Drawing Figures DISPENSING CONTAINER OF FOLDED DISPOSABLE TOWELS 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 (US. Pat. No. 2,990,948). Such towels are commonly sealed individually within foil packages or envelopes such as described in US. Pat. No. 3,057,467, or may be packaged in bulk in a plastic jug or in an impervious wrapper as described in US. 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. lndentations 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.
BRIEF DESCRIPTION OF THE DRAWINGS Novel features and advantages of the present invention will become apparent to one skilled in the art from a reading of the following description in conjunction with the accompanying drawings wherein similar reference characters refer to similar parts and in which:
FIG. 1 is a top plan view of a sealed container which is one embodiment of this invention;
FIG. 2 is a cross-sectional view taken through FIG. 1 along the line 2-2 showing in phantom outline one corner of the cover sheet being peeled from the container;
FIG. 3 is a top plan view of the container shown in FIGS. 1 and 2 after the cover sheet is removed;
FIG. 4 is a cross sectional view taken through FIG. 3 along the line 44 with the inner lid being flexed and removed;
FIG. 5 is a top plan view of the receptacle of the container shown in FIG. 3 and 4 after the inner lid has been removed; and
FIG. 6 is a bottom plan of the container shown in FIGS. 1-5.
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 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 l2 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.
