Description

This disclosure generally relates to a rolled paper product dispensing system.

BACKGROUND

Systems dispensing consumable products are ubiquitous in many environments today. For example, consumable product, e.g., hand towel, dispensers are commonplace in many private, semi-private and public washrooms, break rooms, kitchens and work spaces. It is often desirable to product as many sheets as possible on a paper product roll to reduce the number of times the dispenser needs to be refilled. It is also desirable in many environments to minimize the form factor or footprint of the dispenser to make it less intrusive. Balancing these two competing interests can be quite challenging.

SUMMARY

In general, the subject matter of this specification relates to a paper product dispenser for rolled paper products. One aspect of the subject matter described in this specification can be implemented in systems that include a housing comprising a front, a back, two sides and a product holding area defined at least in part by the front, back and two sides; a first roller extending in a direction from one side to the other and positioned in an upper portion of the product holding area, and

a second roller extending in a direction from one side to the other and positioned in a lower portion of the product holding area, wherein the first and second rollers are configured to pass through a core of a rolled paper product in the product holding area and to engage a top and bottom, respectively, of the core. Other embodiments of this aspect include corresponding apparatus and methods.

Yet another aspect of the subject matter described in this specification can be implemented in a method including unwinding an elliptically shaped rolled paper product in a dispenser, wherein the dispenser has a first roller inserted into and engaging a top portion of a core of the rolled paper product and a second roller inserted into and engaging a bottom portion of the core. Other embodiments of this aspect include corresponding apparatus and systems.

In some implementations, the systems, apparatuses and methods described herein have one or a combination of the following features. The first roller and second rolled are in a same vertical plane. The rolled paper product are hand towels. The roller paper product has an unwound length of between 1500 and 2000 feet. The rolled paper product is tubeless. The first roller and second rollers are configured to rotate as the rolled paper product is unwound and dispensed.

The first and second rollers are at least five inches apart. The first and second rollers are at least seven inches apart. The first and second rollers are at least nine inches apart. The first and second rollers are configured to unwind the rolled paper product in a counterclockwise direction. The core has an elliptical shape. The rolled paper product has an elliptical shape.

Particular embodiments of the subject matter described in this specification can be implemented so as to realize one or more of the following advantages. It is desirable to minimize the depth of a dispenser (e.g., the distance the dispenser protrudes horizontally out from the wall or other surface it's mounted on). For circular rolls minimizing the dispenser's depth results in a small diameter roll, which has a shorter length than a comparable roll with a larger diameter. To accommodate a reduced depth but not give up roll length the dispenser described herein is configured to hold elliptically shaped rolls, which allows the dispenser to have a reduced depth without sacrificing roll length—as the roll is elongated in the vertical direction (height) which is often a less critical design dimension.

The details of one or more implementations of the subject matter described in this specification are set forth in the accompanying drawings and the description below. Other features, aspects, and advantages of the subject matter will become apparent from the description, the drawings, and the claims.

FIG. 1 is a representation of an example paper product dispenser.

DETAILED DESCRIPTION

The present disclosure generally relates to a rolled paper product dispenser that includes upper and lower roller arms configured to be inserted into the core or center of a paper product roll, e.g., hand towel roll, to support the roll in an elliptical shape (or support an elliptical roll) during unwinding and dispensing.

In some implementations, the dispenser includes two roll support rollers. These rollers extend through the core of a paper product roll and support the roll in the dispenser and allow the roll to be unwound for dispensing to a user. More particularly, the rollers are arranged in stacked vertical relation (e.g., in a same vertical plane) such that one roller engages the bottom of the core and the other engages the top of the core to support the roll in an elliptical shape, e.g., in a vertically elongated shape. This allows the dispenser to have a reduced depth and smaller horizontal footprint while not sacrificing the sheet length of the roll as compared to circular shaped rolls. The dispenser is described in more detail below with reference to FIG. 1, which is a representation of an example product dispenser 100.

The dispenser 100 can be, for example, a hand towel dispenser 100, or the like, e.g., bath tissue or wipers/wipers, for rolled paper products 102. A paper product describes sheet materials made from cellulose fibers (e.g., wood pulp), synthetic fibers (e.g., polypropylene) or some combination thereof, and include, for example, bath tissue, paper towels and wipes/wipers. A rolled product is a product that is wound around a core or center axis, e.g., the axis around which the paper product 102 is wound.

The dispenser 100 includes a body 108, e.g., a composite or metal housing, with an outer surface, e.g., an exterior surface of the body 108. The dispenser 100 also includes a product holding area 110 to hold the paper product 102. As shown in FIG. 1, the dispenser 100 is illustrated with the front cover 112 of the body 108 and sides 118 see through to show the product holding area 110 and roll 102.

In some implementations, the product holding area 110 is a space or cavity within the body 108 in which the product 102 can be positioned for dispensing, and can be accessed by rotating the front cover 112 away from the back cover 114 (e.g., the wall mounted portion) by a hinge or the like. The dispenser 100 also includes a first roller 116a and a second roller 116b in the product holding area 110. In combination, the first and second rollers 116 are used to hold and support the paper product roll 102 in an elliptical or (vertically) elongated shape, and to facilitate unwinding the roll 102 for dispensing to a user. In FIG. 1 the roll 102 is shown as rotating in a counterclockwise direction but in other implementations it can rotate in a clockwise direction.

The first roller 116a extends in a direction from one side 118 to the other 118 and is positioned in an upper portion of the product holding area 110. The second roller 116b extends in a direction from one side 118 to the other 118 and is positioned in a lower portion of the product holding area 110. As such, the first and second rollers 116 are configured to pass through the core 119 of a rolled paper product 102 and to engage a top and bottom, respectively, of the core 119. In some implementations, the rollers 116 are in a same vertical plane. The rollers 116 can be, for example, directly connected to and supported by the sides 118 or held by arms or other support devices such that the rollers 116 are not directly connected to the sides 118.

The rollers 116, in some implementations, rotate along with the roll 102 as it unwinds. In other implementations, the rollers 116 are stationary and do not rotate as the roll 102 unwinds but, rather, the roll 102 “slips” across the rollers 116 as it unwinds. In some implementations, the roll 102 is tubeless and has an elliptical shape and/or the roll 102 is held in an elliptical shape by the rollers 116. A roll 102 having or being held in an elliptical or elongated shape describes a roll that has a height (measured in a vertical direction when the roll 102 is positioned for dispensing in a dispenser 100) at least 25% (or at least 50% or at least 75% or at least 100% or at least 150% or at least 200%) greater than its width (measured in a horizontal direction when the roll 102 is positioned for dispensing in a dispenser 100). In some implementations, the rolled paper product 102 has an unwound length of between 1500 and 2000 feet.

In some implementations, the first and second rollers 116 are at least five inches apart, at least seven inches apart or at least nine inches apart. The roll 102 can be perforated thereby defining sheets or a tear bar or the like can cut the unwound portion 127 of the roll 102 for dispensing through the opening 125.

An example process for dispensing paper product is described below. In some implementations, an elliptically shaped rolled paper product 102 (or a paper product roll held in an elliptical shape) is unwound through a dispenser 100 as described above. For example, the dispenser 100 has a first roller 116a inserted into and engaging a top portion of a core 119 the rolled paper product 102 and a second roller 116b inserted into and engaging a bottom portion of the core 119. As the roll 102 is unwound, e.g., either through rotation of the rollers 116 or slipping across the rollers 116, it is dispensed out of the opening 125 to a user.
