The present disclosure relates to a sheet product dispenser, and more particularly to features that provide for the dispensing of sheet product from the dispenser.
Sheet products, such as disposable absorbent wipers or towels for example, have many uses. Disposable wipers are particularly popular with do-it-yourself homeowners and trades people who find wipers valuable for cleaning tools, work areas and their hands. Disposable wipers are also used frequently in factories, on farms and in the boating industry (both commercial and recreational). These are just a few of the wide variety of people and multitude of uses of disposable wipers. Frequently, disposable wipers are used by people who are on the go, whether it be trades people moving from job to job, maintenance people moving from machine to machine within a factory or farmers dealing with issues wherever they come up. Containers of disposable wipers thus are often treated as valuable items of one's normal equipment for performing jobs and are often carried in the back of trucks to job sites along with other tools or on maintenance carts in factories. Disposable wiper containers end up in countless types of places, wherever people do work.
Often, because these containers may be used and stored outside, they can become exposed to inclement weather or they can be indoors in dusty and dirty environments. Mobile and water resistant sheet product containers include a dispensing nozzle or orifice that is typically integrated with the supply of sheet product within the container. Accordingly, such nozzles may only be used with the associated supply of sheet product, and are replaced as part of each replacement supply of sheet product for use within the dispenser. A configuration of the dispensing nozzle is generally adapted for proper dispensing (such as to result in tearing at a pre-scored perforation line) of a particular sheet product media or material. Alternatively, dispensers may utilize nozzles integrated with a lid of the dispenser and therefore require a different lid for each different type of sheet product material for which the nozzle is adapted to dispense. Therefore, each different type of sheet product material to be dispensed requires a different lid, each different lid having associated therewith design and tooling costs. Accordingly, there is a need in the art for a sheet product dispensing arrangement that overcomes these drawbacks.
An embodiment of the invention includes a nozzle for dispensing sheet product. The nozzle includes a base portion oriented substantially perpendicular to a dispense direction of the sheet product and having an inner periphery and an outer periphery. A sloping portion is disposed proximate a center of the base portion and extends from the inner periphery of the base portion toward the center in the dispense direction to terminate at an edge defining an opening of the nozzle. The nozzle further includes a lip portion disposed about the outer periphery of the base portion, and a retention feature extending from the lip portion. The retention feature has a leg portion and a latch portion, the leg portion is oriented substantially parallel to the dispense direction, and the latch portion extends from a free end of the leg portion substantially perpendicular to the dispense direction.
A further embodiment of the invention includes a sheet product dispenser. The sheet product dispenser has a main body with a bottom and side walls that define a top opening and an interior of the main body and a lid removably disposed upon the top opening. The lid includes a nozzle having a base portion oriented substantially perpendicular to a dispense direction of the sheet product with an inner periphery and an outer periphery. A sloping portion is disposed proximate a center of the base portion and extends from the inner periphery of the base portion toward the center in the dispense direction to terminate at an edge defining an opening of the nozzle. The nozzle further includes a lip portion disposed about the outer periphery of the base portion. The retention feature has a leg portion and a latch portion, the leg portion is oriented substantially parallel to the dispense direction, and the latch portion extends from a free end of the leg portion substantially perpendicular to the dispense direction.
These and other advantages and features will be more readily understood from the following detailed description of preferred embodiments of the invention that is provided in connection with the accompanying drawings.
Referring to the exemplary drawings wherein like elements are numbered alike in the accompanying Figures:
An embodiment of the invention provides a nozzle for the dispensing of sheet product. In one embodiment, the nozzle is removably attached to a lid of the dispenser, thereby allowing the nozzle to dispense more than one supply (such as a roll for example) of sheet product, and allowing different nozzles to be utilized with the same container and lid to dispense different types or sizes of sheet product. As used herein, the terms “sheet product” and “sheet products” are inclusive of natural and/or synthetic cloth or paper sheets. Further, sheet products can include both woven and non-woven articles. Examples of sheet products include, but are not limited to wipers, napkins, tissues, and towels.
The container 30 is illustrated in the various Figures as being generally cylindrical in shape, which is a spatially efficient configuration to house a roll of towels having a vertical axis, and is an economical configuration with regard to container material costs. However, the container 30 may have other shapes as desired.
The roll 65 of sheet product may be provided without a central core so that a free end 75 in the center portion of the roll 65 is accessible. The roll 65 is positioned with its axis extending vertically, and the roll 65 of sheet product is consumed from its center to its outside. The roll 65 may be of any size to fit within the dispenser 10. In one embodiment, the diameter of the roll 65 ranges from about 6 to about 12 inches. In other embodiments, a roll may have a diameter of approximately 8 inches or of approximately 10 inches.
To seal the container 30, such as to improve water tightness for example, opening 110 may be covered with an openable cover 115.
As used herein, the term “substantially” with reference to relative orientation, shall represent a minimal deviation, such as resulting from manufacturing, design, and assembly tolerances, for example.
The sloping portion 135 is disposed proximate a center 155 of the base portion 130 and extends from the inner periphery 142 toward the center 155 in the upward direction 140. The sloping portion 135 terminates at an edge that defines the opening 110. In one embodiment, the sloping portion 135 of the nozzle 60 defines a continuous conical surface 145 having a straight, sloped surface that originates from the base portion 130 at a first radial distance 150 from the center 155 of the nozzle 60 and terminates at the edge (indicated generally by reference numeral 110) that defines an opening 110 at a second radial distance 160 from the center 155. The first radial distance 150 is greater than the second radial distance 160. The second radial distance 160 defines the radius of the opening 110.
The raised portion 135 of the nozzle 60, specifically the radius of the opening 110 defined by the second radial distance 160, is configured such that the opening 110 provides frictional resistance to the removal of the sheet product disposed within the container 30. In an exemplary embodiment, the opening 110 is configured such that a strength of a portion of the sheet product absent perforations is greater than the frictional resistance provided by the opening 110 of the nozzle 60. Further, a strength of a portion of the sheet product having perforations is less than the frictional resistance provided by the nozzle 60. Accordingly, as the portion of the sheet product having the perforations is withdrawn beyond the opening 110 and in response to a continued application of force to the sheet product, the frictional resistance of the opening 110 causes a first individual sheet to separate from a next individual sheet at the perforations, leaving a small portion of sheet product disposed beyond the opening 110 for subsequent dispensing (or withdrawal) of the next individual sheet.
The cover 115 has a cap portion 165 and a wall portion 167. The wall portion 167 of the cover 115 is disposed proximate an outer periphery 168 of the cap portion 165 and is oriented substantially perpendicular to the cap portion 165. Cover 115 pivots about pivot point 170 of hinge 125. In response to the cover 115 being pivotally coupled with the nozzle 60, the wall portion 167 of cover 115 interfaces with the wall portion 137 of the nozzle 60, which, in conjunction with cap portion 165 thereby seals the nozzle 60, particularly the opening 110 and the sheet product within the interior 70 of container 30. In an embodiment, the wall portion 167 is defined by an outer diameter having a dimension of approximately x, and the outer diameter of wall portion 167 interfaces with the inner diameter of circumferential wall portion 137 to seal the container 30. As used herein, the term “approximately” represents deviation resulting from manufacturing and design tolerances as well as a desired interface fit, such as one of an interference, slip, or transition fit, for example.
While an embodiment has been depicted having circumferential wall portions 137, 167, it will be appreciated that scope of the invention is not so limited, and is contemplated to include other wall portion geometry, such as square, rectangular, hexagonal, octagonal, or any other desired shape for example. Further, while an embodiment has been described with the outer diameter of the cap portion 165 of the cover 115 interfacing with an inner diameter of the circumferential wall portion 137 of the nozzle 60, it will be appreciated that the scope of the invention is not so limited, and is contemplated to include other arrangements, such as the inner diameter of the cap portion 165 of the cover 115 interfacing with an outer diameter of the circumferential wall portion 137 of the nozzle, for example.
The unitary assembly 120, including the nozzle 60, is assembled or attached to the lid 55 via the leg portion 185 and latch portion 200 of the retention feature 175. In an embodiment, the unitary assembly 120 is removably assembled with or attached to the lid 55 from an interior side 195 (also herein referred to as an “underside”) (
While an embodiment has been described with the leg portion 185 of the retention feature 175 having a radially inward bias and the latch portion 200 disposed upon the radially inward side of the leg portion 185, it will be appreciated that the scope of the invention is not so limited, and may apply to other retention feature 175 arrangements, such as the leg portion 185 having a radially outward bias and the latch portion 200 disposed upon the radially outward side of the leg portion 185 of the retention feature 175, for example.
In response to withdrawal or dispensing of sheet product from the interior 70 in the upward direction 140, interaction between the sheet product and the opening 110 results in a frictional force upon the nozzle 60 directed in the upward direction 140. This frictional force is transferred from the nozzle 60 to the lid 55 via contact interface 210. The frictional force is further transferred from the lid 55 to the main body 35 via the connection 57 between the lid 55 and the body 35. Insertion of the assembly 120 into the lid 55 via the interior side 195, in conjunction with the retention features 175, and openings 180, prevents separation of the assembly 120 from the lid 55 in response to the frictional force that results from withdrawal of the sheet product.
With reference back to
Different sheet product materials may have different characteristics, such as thickness and perforation strength for example. Therefore the desired frictional force that results from withdrawal of different sheet product may vary in order to properly dispense the sheet product, such as to cause the sheet product to tear at perforations for example. Accordingly, nozzles 60 having different opening 110 configurations may be selected for use with the dispenser 10 in conjunction with different sheet product materials. Further, selection of appropriate nozzle 60 configuration and material is contemplated to provide useful function for at least three replacement supplies of sheet product.
Insertion of the assembly 120 into the lid 55 further allows a single design of the lid 55 and main body 35 to be utilized with more than one configuration of nozzle 60, such as more than one nozzle opening 110 configuration for example. Flexibility to use the same main body 35 and lid 55 of the container with different sheet product materials is contemplated to reduce overall costs related to dispenser 10 manufacture. It will be appreciated that costs of tooling are often related to the size of the tools. Therefore, for example, fixed costs related to tooling of the container 30 and lid 55, which represent the larger (by size) of dispenser 10 components may be applied across more units produced, with any variation required (such as to accommodate different sheet product materials for example) to be accommodated via different unitary assemblies 120, having a smaller and less costly tool. Additionally, it will be appreciated that replacement of the comparatively smaller assembly 120 following wear of the nozzle 60 is contemplated to be more cost effective than replacement of an entire lid 55 into which the nozzle 60 has been integrated.
Insertion of the assembly 120 into the lid 55 such that it can be subsequently removed also allows for an end user to purchase one dispenser 10 that can be used with a variety of sheet product materials by removing and inserting into the lid 55 the appropriate nozzle and cover assembly 120 for the sheet product to be dispensed. As such, the end user need not maintain an inventory of different dispensers 10 that are each suited to dispensing particular sheet product.
