Embodiments of the present disclosure relate to a hanging product including a paper or nonwoven material in a container, and the container for the paper or nonwoven material.
There is an ever-increasing demand for novel ways to dispense paper materials such as facial tissue, bathroom tissue, paper towels, napkins, absorbent paper, wet wipes and the like.
In particular, with the increase in the number of items stored on counters and shelves and the resulting decrease in available counter space, there is a need to provide hanging dispensing products of paper materials, which reduce or eliminate the amount of counter space required. Thus, hanging dispensers or products, which eliminate the need for any counter space usage, are consumer preferred.
In addition, paper materials are frequently used in areas with exposure to liquids and moisture such as kitchens, bathrooms, restaurants and food carts. Conventional cartons of paper materials, when placed on counters, can be damaged by associated liquid spills. By providing a dispenser that hangs, the product's usefulness to consumers is enhanced.
Conventional hanging products have various issues with the dispensing function of each. For example, known hanging products are described in U.S. Pat. No. 6,439,386, U.S. Pat. No. 6,769,565, and U.S. Pat. No. 6,877,634, each assigned on its face to Kimberly-Clark Worldwide, Inc.
Thus, there is a need to provide an economical solution to the problem of how a hanging dispenser functions. For example, there is a need to provide an improved dispensing function, where paper materials can be dispensed with minimal effort, minimal tearing, and/or minimal wadding. For example, there is a need to improve the dispensing of the entire stack of paper material. For example, there is a need to ensure that the last few paper materials (e.g., 10-50 napkins) will individually dispense, instead of falling out of the end of the container or dispensing simultaneously.
For the foregoing reasons, there is a need for a hanging product including a paper material in a container, and the container for the paper material, that reduces the need to place the dispenser on a counter, while providing dispensing with minimal effort, minimal tearing, and/or minimal wadding, and/or improved dispensing characteristics that address other drawbacks of conventional hanging products.

With reference to the figures, and more particularly to
The disclosure describes various embodiments and the separate discussion of each should not be construed to limit the invention, or otherwise to exclude any other embodiments, adaptations, variations, modifications and equivalent arrangements. Features from the various embodiments may be combined together with features from other embodiments.
Referring to
The container 10 may be any size or shape useful for containing the paper material 12. The container 10 may be sized small enough so as to keep the paper material 12 from moving around in the container 10, but large enough to not restrict the dispensing of the paper material 12.
Referring to
In
In
The container 10 may be of any material useful for containing the paper material 12. For example, the material may be a plastic, such that the container is a plastic bag. Exemplary plastic materials include, but are not limited to, thermoplastics and thermosetting polymers, including polyethylene, polypropylene, polystyrene, polyvinyl chloride, and polytetrafluoroethylene (PTFE). The material may be biodegradable, for example a plastic comprising corn starch. For example, the material may be a cardboard, carton stock, heavy paper, and the like. The material may be coated with a wax, strengthening agent, friction reducing agent or a waterproofing agent.
In an embodiment, the container 10 is a poly bag that is gravity fed.
In an embodiment, the absorbent paper material 12 is substantially in contact with an interior surface of sidewall 20 of the container 10, and not housed within a second container or carton. The interior surface may be treated with a friction reducing agent.
In an embodiment, the container 10 is disposable upon depletion of the paper material 12. In an embodiment, the container 10 is refillable upon depletion of the paper material 12. A refillable container could be used with a paper material purchased in bulk.
A first opening 22 is provided into the interior of the container 10. In an embodiment, the first opening 22 is located in the second end 18. In an embodiment, the first opening 22 is the only opening into the interior of the container 10.
Any size, style, or location of opening configured to dispense a paper material 12 through the endwall from the interior of the container 10 is possible. The type of paper material 12 being dispensed may dictate the style or size of opening. For example, the opening may be a slit, an oval, a rectangle, a square, a circle, a dog bone, a curved shape, an S-shape, or the like.
In an embodiment, the first opening 22 extends across the width of the container 10. The width being the direction of the first opening 22, the length being a perpendicular direction. The width may be the entire width or at least substantially the entire width. For example, the first opening 22 may extend across at least the width of the paper material 12 in the container 10. For example, the first opening 22 may extend across an entire width of the container 10, but not extend up the sidewall 20. Alternatively, the first opening 22 extends across an entire width of the container 10 and extends slightly up the sidewall, such as up to 25 mm.
Referring to an embodiment in FIGS. 2A,B, the first opening 22 may be formed by pulling apart the material of the second end 18. This may be done at a perforation line 34.
Referring to an embodiment in FIGS. 2C,D, the first opening 22 may be covered by at least one removable strip 36 as is conventionally practiced with facial tissue cartons. For instance, a removable strip 36 may be created by lines of perforation 35 in the container 10. The removable strip 36 is stripped from the container 10 prior to dispensing the paper material 12. The first opening 22 may be formed by pulling off the removable strip 36, e.g., a strip of material on the second end 18. The removable strip 36 may be formed integrally with the material of the second end 18. The removable strip 36 may have a uniform width of, for example, from 1 mm to 25 mm, or from 5 mm to 15 mm.
The removable strip 36 may be completely removed or partially removed from the container 10 when forming the first opening 22. When the removable strip 36 is partially removed from the container 10, the strip 36 may act as a tab or flap that can reseal with the container 10 to protect the paper material 12.
Referring to an embodiment in FIGS. 2E,F, one end of the strip 36 may include an attachment device 38, such as an adhesive or adhesive receiving area, in order to reattach the strip 36 to the container 10 for sealing.
Referring to an embodiment in FIGS. 2G,H, a removable strip 36 may be removed to form the first opening 22. The first opening 22 may include a protective film 25 with a dispensing slit 27.
The first opening 22 may be pre-formed, for example by cutting the material of the second end 18 during manufacture. The pre-formed first opening 22 can be covered by a removable sheet of protective material (not shown).
Referring to an embodiment in
The insert 14 extends across an entire width of the container 10 and up at least a portion of each respective sidewall. Referring to an embodiment in FIGS. 4A,B, the insert 14 has a base portion 40 and two side portions 42, 44. For example, the side portions 42, 44 may extend far enough up the sidewall to provide support for the overall insert 14, and to ensure that the base portion 40 stays flat. The side portions 42, 44 may extend only slightly up the sidewalls, for example, from 10 mm to 100 mm, or from 40 mm to 80 mm, or from 60 mm to 80 mm. Alternatively, the side portions 42, 44 may extend at least halfway up the sidewalls or substantially all the way up the sidewalls.
The insert 14 may have fold or scoring lines 43,45 where the side portions 42,44 meet the base portion 40 in order to ensure a sharp bending, and not a gentle bending. In an embodiment, the side portions 42,44 meet the base portion 40 at a 90°±5° angle.
The insert 14 may be formed from a rectangular piece of material. Alternatively, the insert 14 may be shaped so that the side portions 42, 44 are rounded.
The insert 14 has an insert opening 50 that may be designed to match the first opening 22 of the container 10. Alternatively, the insert opening 50 may have different size or shape than the first opening 22. Any size, style, or location of opening configured to dispense a paper material 12 through the insert 14 from the interior of the container 10 is possible. The type of paper material 12 being dispensed may dictate the style or size of insert opening 50. For example, the opening may be a slit, an oval, a rectangle, a square, a circle, a dog bone, a curved shape, an S-shape, or the like.
Referring to an embodiment in FIGS. 4A,B, the insert opening 50 extends across an entire width of the container 10 and into the side portions 42,44. The opening 50 may extend 10-100 mm, or from 30-50 mm into the portions 42, 44. Referring to an embodiment in FIGS. 5A,B, the insert opening 50 extends across the width of the second end area 18, but does not extend up the sidewall 20. This may be the entire width or at least substantially the entire width. For example, the insert opening 50 extends across at least the width of the paper material 12 in the container 10.
In an embodiment, the base portion 40 lays flat at the second end 18, and holds the paper material flat, or relatively flat, for proper dispensing, without adding too much pressure to the sides of the paper material 12, which may cause the napkins to tear and/or wad while dispensing. Relatively flat indicates that the base portion 40 experiences relatively little bowing. For example, the base portion 40 may have bowing height change of less than 10%, or less than 5%, of the width (X) of the base portion 40.
In an embodiment, the insert 14 will allow the paper material to dispense in an uninterrupted manner, such that the paper material displays essentially perfectly. For example, embodiments provide an improved dispensing function, where paper materials can be dispensed with minimal effort, minimal tearing, and/or minimal wadding. For example, embodiments improve the dispensing of the entire stack of paper material. For example, embodiments ensure that the last few paper materials (e.g., 10-50 napkins) will individually dispense, instead of falling out of the end of the container or dispensing simultaneously.

The insert 14 may be of any material useful for supporting the paper material 12. For example, the material may be plastic, cardboard, carton stock, heavy paper, and the like. The insert 14 may be corrugated for extra stability. The corrugation direction may be in the width (X) direction of the insert 14. The material may be coated with a wax, strengthening agent, friction reducing agent or a waterproofing agent.
In an embodiment, the insert may be of the same material as the container 10. For example, the insert may be integrally formed with the container
The paper material 12 may be napkins, absorbent paper, bathroom tissue, facial tissue, toilet paper, paper towels, wet wipes, dry wipes and the like. While paper material is mentioned, other material, such as nonwoven material, a natural material, or a synthetic material may be contained in the container 10. The paper material 12 may be stacked. The paper material 12 may be interfolded, which may assist with dispensing. Exemplary embodiments for how the paper material can be interfolded are described in U.S. Pat. No. 7,611,765, which is expressly incorporated herein by reference. The interfolded paper material 12 may substantially rectangular having parallel first edges and parallel second edges. The paper material 12 may be connected with perforated attachment lines.
The paper material 12 may be single ply paper napkins having a basis weight of at least 8 lb per unfolded sheet, for example from 8 to 30 lb per unfolded sheet, for example about 10 to 20 lb per unfolded sheet. The expression of basis weight in pounds as used herein is with reference to a stack of 500 unfolded single ply sheets each measuring 24 by 36 inches.
In an embodiment, the container 10 may hold at least 50 napkins, for example at least 400 napkins, for example at least 500 napkins, for example 50 to 1000 napkins.
The container 10 may include an attachment member 60, from which to hang the container 10 for dispensing. The attachment member 60 should be sturdy enough to allow for hanging of the container 10, and to withstand the force of withdrawing a paper product 12 and the force of being bumped into. Examples of attachment members, by way of illustration and without limitation, include adhesives, hook and loop materials, tabs and slots, lines of perforation with or without a strip, clips, and hooks. For example, the attachment member 60 may be a single member placed at the center of the width of first end 16. For example, the attachment member 60 may be two members, placed on either side of the width of the first end 16. For example, the attachment member 60 may be a hanger, either inserted into the container 10 or attached to the exterior of the container 10. For example, the attachment member 60 may be a hole(s) in the container, optionally a reinforced hole(s). For example, the container may have a double seal with a hole(s) through multiple layer of material.
