Embodiments described generally relate to disposable cutlery. More particularly, embodiments described relate to removable bands for retaining stacks of disposable cutlery.
Disposable cutlery can be typically found in fast-food and take out restaurants as well as populated venues like sporting events, airports, train stations and the like. Cutlery dispensers have been used to provide a protective environment for the disposable cutlery housed within. Conventional cutlery dispensers, however, have challenges and issues delivering pieces of cutlery to a consumer in a repeatable and reliable manner Conventional cutlery dispensers typically suffer from one or more pieces of cutlery getting jammed within the dispenser and not able to be dispensed without time consuming attention and disassembly, which exposes the contents inside, i.e. the cutlery, to the surrounding environment. Conventional cutlery dispensers also have difficulties associated with re-loading cutlery and maintaining a reliable supply of cutlery for user demand.
Non-cartridge-type dispensers have used bands or other types of wrapping to contain a stack of cutlery during shipping and storage. Conventional methods for confining the plurality of cutlery are typically removed after the cutlery has been loaded into the dispenser. In order to do this, the band should be able to sufficiently store and hold the stack together prior to and during the loading/re-filling process as well as be able to be removed after the stack of cutlery is loaded in place without disturbing the stack within the dispenser. Conventional bands have not been able to reliably perform these functions.
There is a need, therefore, for an improved band to hold a stack of cutlery together during storage and transit, but at the same time capable of being removed from within a dispenser without disturbing the loaded stack.
A removeable band for confining a stack of cutlery pieces is provided. In one embodiment, the band includes a body having a first end and a second end. The body can be an elongated strip of fiber-based material. A window can be formed through the body and an adhesive can be disposed at least partially over the window. The adhesive can be configured to adhere a portion of the first end of the body to a portion of the second end of the body when the ends of the body overlap to form a continuous band.

Considering the various band 50 configurations in more detail,
By “end” of the band 50, it is meant the opposing extremities of the body 51 of the band 50. The term “end” is not meant to be limited to the most extreme boundary of the body 51 but is meant to refer to and include a portion of the body 51 that is adjacent or near the extreme boundary. This can include the last 1%, 5%, 10%, 20%, or 25% of the length of the body 51 as measured from the very end point of the body 51. The portion of the body 51 between its ends 56, 57 is the mid-section 58 of the body 51. The opening 55 can be entirely or only partially located in the mid-section 58 of the body 51. The opening 55 can be entirely or only partially located in one end 56 or 57 of the body 51.
In certain embodiments, the band 50 can include more than one opening 55. For example, the band 50 can include two, three, four, five, or six or more openings 55 disposed about the body 55, much like the holes on a belt. And as mentioned above, each opening 55 provides a passageway 65 for an adhesive or other form of attachment 66 to directly adhere to the tail-side 57 of the band 50, or directly to the stack of cutlery 10, or a portion of both.
In the “open” window 55 configuration, a small amount of adhesive residue 67 may be left on the stack 10 as shown in
To further illustrate embodiments of the band 20,
Considering the body 51 of the band 50 in more detail, the body 51 can be an elongated strip of fiber-based material, polymeric material or combinations thereof. The body 51 can also be a combination of materials such that one region or section can be made from, for example, a fiber-based material and another region or section can be made from a polymeric material or a different kind of fiber-based material.
A suitable fiber-based material can be a paper-based material. In one form, the band 10 can be a strip of paper or paperboard. Commercially available paperboard material that may be used include, but is not limited to, solid bleached sulfate (SBS) board, bleached virgin board, unbleached virgin board, recycled bleached board, recycled unbleached board, or any combination thereof.
Each side 52, 53 of the body 51 can be uncoated or at least partially coated with one or more suitable coatings materials. Either side 52, 53 of the body 51 or both sides 52, 53 may be uncoated, e.g., free or substantially free from wax, clay, polymeric, or other coating material. Where applied, the coating can cover the entire area and/or length of the body 51 or only a portion thereof. For example, the coating can be applied at the very extreme end of the body 51 or about 45%, about 30%, about 20%, about 15%, about 10%, about 5%, or about 3% of the way from the end 57 to the mid-section 58 of the body 51. The same can be done on the other end 56.
The total thickness of the resulting monolayer and/or multilayer coating 30 can vary. The coating 30, for example, can have a thickness ranging from a low of about 0.002 mm, about 0.01 mm, or about 0.1 mm to a high of about 0.15 mm, about 0.2 mm, or about 0.35 mm.
The coating can be or can include one or more waxes, one or more clays, and/or one or more polymeric materials. The coating can be or can include, for example, polyethylene, polypropylene, polyester, polyethylene terephthalate, polyamide or any combination thereof. In a particular embodiment, the coating can be or includes polyethylene or polylactic acid (“PLA”). In another example, the coating can be or can include a butylene polymer, ethylene polymer, high density polyethylene (HDPE) polymer, medium density polyethylene (MDPE) polymer, low density polyethylene (LDPE) polymer, linear low density polyethylene (LLDPE), propylene (PP) polymer, isotactic polypropylene (iPP) polymer, high crystallinity polypropylene (HCPP) polymer, ethylene-propylene (EP) copolymers, ethylene-propylene-butylene (EPB) terpolymers, propylene-butylene (PB) copolymer, an ethylene elastomer, ethylene-based plastomer, propylene elastomer and combinations or blends thereof. In another example, the coating can be or can include polypropylene, polyvinylchloride (PVC), polymethylpentene, polybutene-1, polyolefin elastomers, polyisobutylene, ethylene propylene rubber, or any mixture or combination thereof.
The coating can be applied to the body 51 using any suitable process. For example, the coating can be applied by laminating, brushing, spraying, or extrusion. One or more coatings or layers of coatings can be applied. The one or more coatings can be applied on one or both sides 52, 53 of the body 51, or to any portion of one or both sides 52, 53. The number of layers of coatings can be different and can vary across the length of the body 51 and at various locations about the body 51.
Each band 50 can be about 0.05 inches to about 4 inches in width, or from about 1.0 inches to about 3.0 inches in width. The width is defined by the need to prepare a tight confinement of the plurality of cutlery and the need to readily remove the band after loading the stack inside a dispenser. It is possible that each band 50 will need to be smaller or larger to account for the specific shapes of the cutlery being bound and the number of cutlery pieces being stacked together. The overall size of each band 50 can be adjusted, as needed, by the amount of overlap at its ends 56, 57 to obtain a desired size of the loop.
In certain embodiments, a removeable tab can be formed within the band 50. The tab can be defined by a first set of one or more perforations formed in the body 51 and axially spaced from a second set of one or more perforations formed in the body 51 such that the perforations allow the tab to be separated and removed from the rest of the band 50, disconnecting the loop.
In additional embodiments, a second adhesive or second adhesive section can be used to secure the ends 56, 57 of the band 50. The second adhesive can be used in addition to or in lieu of the adhesive 66 in or over the opening 55. In certain embodiments, the second adhesive section can be located on one or both sides 52, 53 of the band 50, anywhere along the length of the body 51. The second adhesive section is preferably located away from the opening 55. The second adhesive section can be or can include one more adhesives or adhesive systems disposed thereon. Such adhesives or adhesive systems can be any suitable self-sealing, pressure sensitive or hot melt adhesive. The second adhesive can be applied by spraying, brushing, flexographic printing, rotogravure printing, offset printing, screen printing, or any other suitable coating method.
Referring again to
The access door 130 can swing opened and closed using one or more hinges attached to the dispenser housing 110. The hinge locations can vary and can be located at the top, bottom, or side of the dispenser housing 110. The access door 130 can include one or more fill level apertures or windows 162 that align with corresponding fill level apertures or windows 172 disposed on the dispense chassis 150. As explained further below with reference to
The cutlery dispenser 100 can accept any suitable number of dispense chassis 150. This particular dispenser 100 has room for up to three dispense chassis 150, as depicted. The cutlery dispenser 100 of
Each dispense chassis 150 can be configured with a gauging device to help approximate the number of cutlery within the dispense chassis 150.
Movement of the first gauge arm 2010 about its pivot connection 2012 can be translated to movement of the second gauge arm 2020 about its pivot connection 2025 to move the indicator 2030 relative to the gauge window 172. In an alternative embodiment that is not shown, the first gauge arm 2010 and the second gauge arm 2020 can be fixed together and can pivot such that movement of the first gauge arm 2010 about the pivot 2012 can be translated into movement of the second gauge arm 2020 to move the indicator 2030 relative to the gauge window 172.
The indicator 2030 can display different quantities of cutlery within the stack 2205, the quantities being visible through the gauge window 172. The indicator 2030 can have different quantities printed on different parts of the indicator 2030. The different quantities can be visible through the gauge window 172 one at a time or multiple quantities can be displayed to show that the level is between the quantities displayed. For example, the indicator 2030 could have “Full” and/or a green color printed on the indicator 2030 that is visible through the gauge window 172 when the dispense chassis 150 has more than a certain amount of cutlery in the cutlery stack 2205, more than 50% full, more than 60% full, more than 70% full more than 80% full, or more than 90% full; “Half-Full” and/or a yellow color printed on the indicator portion that is visible through the gauge window 172 when the dispense chassis 150 has certain amounts of cutlery in the cutlery stack 2205, between 10% full and 90% full, between 20% full and 80% full, between 30% full and 70% full, between 40% full and 60% full; and/or “Empty” and/or a red color printed on the indicator 2030 that is visible through the gauge window 172 when the dispense chassis 150 has less than a certain amount of cutlery, such as less than 5, less than 4, less than 3, less than 2, or none in the stack 2205. Alternatively, the colors can be used to indicate how many full stacks of cutlery (the number of cutlery in a full stack of cutlery refills can vary) can be added to the dispense chassis 150. For example, where a full stack of cutlery refills is thirty, green can indicate that less than one full stack of cutlery refills will fit within the dispense chassis 150. Yellow can indicate that more than one full stack of cutlery refills can be added to the dispense chassis 150, and red can indicate that two full stacks of cutlery refills can be added to the dispense chassis 150.
The first gauge arm 2010 can include any number of extensions or prongs 2040 that are configured to contact a side of the stack 2205. For example, the first gauge arm 2020 can include 1 prong, 2 prongs, 3 prongs, 4 prongs, or 5 prongs disposed along its length. In one particular embodiment, the first gauge arm 2010 has two prongs as shown in
The chassis housing 310 can include a gauge aperture or opening 2045 formed through an internal wall 310A through which the prong(s) 2040 can extend and contact a side of the stack 2205. The gauge aperture or opening 2045 can be a recessed section or cut away formed in the internal wall 310A, allowing an adjacent prong 2040 to pass through. Referring to the embodiment shown in
The gauge window 172 can have any suitable height, such as about 2 mm, 3 mm, 5 mm or more, and can display colors, numbers, percentages, or any other indicator to indicate the number of cutlery or stack height within the dispense chassis 150. The first gauge arm 2010 can swing with gravity and with or without a spring assistance. The weight and/or the center of gravity of the first gauge arm 2010 can be adjusted to change how the cutlery stack gauge 2000 operates. The position and/or the number of the prongs 2040 can be adjusted to provide more precise level indicators. Additionally, in an embodiment not shown, the first gauge arm 2010 can be located inside the housing wall 310A such that any one or more of the prongs 2040 can directly contact the cutlery stack 2205 without passing through an opening 2045.
