Description

TECHNICAL FIELD

Field of Use

This disclosure relates to film dispensers. More specifically, this disclosure relates to braking film dispensers that allow rolls of material to be ergonomically dispensed with adjustable tension.

Related Art

Just as a plastic film can be rolled up on a cardboard or paperboard core member and then dispensed as a moisture-proof wrapping for food by unrolling the material onto food placed on or inside a dish, sheets of material can be used to wrap goods. For example, the plastic film, membrane, or sheet of any suitable material is often rolled up on cylindrical cardboard or paperboard core member or other similar device such as a spool or roll made of another material that allows the film or sheet to be dispensed to facilitate the wrapping of goods. This can protect the goods from dust, water, and other contaminants found in their environment. In many situations, the dispensing from such a film roll is done manually. Especially for one-time or disposable use by a consumer, the spools or tools conventionally used to dispense the film or sheet can been prohibitively expensive and can be heavy and therefore difficult to handle, and the mechanism used to create tension in the film can be difficult to use and adjust.

DETAILED DESCRIPTION

The present disclosure can be understood more readily by reference to the following detailed description, examples, drawings, and claims, and their previous and following description. However, before the present devices, systems, and/or methods are disclosed and described, it is to be understood that this disclosure is not limited to the specific devices, systems, and/or methods disclosed unless otherwise specified, as such can, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to be limiting.

The following description is provided as an enabling teaching of the present devices, systems, and/or methods in their best, currently known aspect. To this end, those skilled in the relevant art will recognize and appreciate that many changes can be made to the various aspects described herein, while still obtaining the beneficial results of the present disclosure. It will also be apparent that some of the desired benefits of the present disclosure can be obtained by selecting some of the features of the present disclosure without utilizing other features. Accordingly, those who work in the art will recognize that many modifications and adaptations to the present disclosure are possible and can even be desirable in certain circumstances and are a part of the present disclosure. Thus, the following description is provided as illustrative of the principles of the present disclosure and not in limitation thereof.

As used throughout, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to a quantity of one of a particular element can comprise two or more such elements unless the context indicates otherwise.

Ranges can be expressed herein as from “about” one particular value, and/or to “about” another particular value. When such a range is expressed, another aspect comprises from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about” or “substantially,” it will be understood that the particular value forms another aspect. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint.

For purposes of the current disclosure, a material property or dimension measuring about X or substantially X on a particular measurement scale measures within a range between X plus an industry-standard upper tolerance for the specified measurement and X minus an industry-standard lower tolerance for the specified measurement. Because tolerances can vary between different materials, processes and between different models, the tolerance for a particular measurement of a particular component can fall within a range of tolerances.

As used herein, the terms “optional” or “optionally” mean that the subsequently described event or circumstance may or may not occur, and that the description comprises instances where said event or circumstance occurs and instances where it does not.

The word “or” as used herein means any one member of a particular list and also comprises any combination of members of that list.

In one aspect, a film dispenser and associated methods, systems, devices, and various apparatuses are disclosed herein. In one aspect, the film dispenser can comprise a holding member. In another aspect, a rotating member can be joined to the holding member in a rotatable fashion along a common longitudinal axis so that the rotating member may rotate with a spool of wrap or film while the user comfortable holds the holding member. The term “holding member” should be interpreted broadly and should be applied to any member that can be held in a user's hand and that can allow rotation of the rotating member or a film roll about the longitudinal axis of the holding member. The term “rotating member” should be interpreted broadly and should be applied to any member that can rotate relative to the holding member and thereby facilitate dispensing of the film. While the film dispenser can be particularly useful in applications for dispensing plastic film, sheets, or wrap, it can be used with any other dispensable material, such as cloth or metal, of any desired thickness that is used to enclose, enwrap, cover, or otherwise protect articles. It would be understood by one of skill in the art that the disclosed film dispenser is described in but a few exemplary aspects among many. No particular terminology or description should be considered on the disclosure or the scope of any claims issuing therefrom.

As shown in FIG. 1, a film dispenser 100 can comprise a holding member 102. The film dispenser 100 can also comprise a rotating member 104. The holding member 102 and the rotating member 104 can be of a substantially annular or tubular configuration and can be formed as separate components. The holding member 102 can define a longitudinal axis A102 extending from its first end 106 to its second end 108. The holding member 102 can also define a radial direction R102 extending from and about the longitudinal axis A102.

The rotating member 104 can comprise a sleeve 115 and define an axis of rotation A104 extending from its first end 110 (shown in FIG. 7) to its second end 112. The rotating member 104 can comprise a plurality of ridges or ribs 114. Nine ridges 114a thru 114i are shown in FIG. 1. In various aspects, as many as eighteen ridges 114 can be used, each of which can be evenly spaced around the periphery. In yet another aspect, any number of ribs 114 can be used including a single rib or a plurality of ribs—including more than eighteen in total, each of which need not be evenly placed about the periphery of the rotating member. Each of the ribs 114 can be placed on an exterior surface 116 of the second end 112 of the rotating member 104 and can be configured to engage an inner bore of a film roll 902 (shown in FIG. 12), which can be a spool or hollow cardboard core of stretch wrap film, other film, or other material 910 (shown in FIG. 13).

The rotating member 104 can also comprise an annular flange 118 (shown in FIG. 7), which can contact the holding member 102 at its first end 106 or nearly so when the holding member 102 is assembled to the rotating member 104. The flange 118 can define a thickness along the axis of rotation A104 and can extend annularly in a direction that is perpendicular to the axis of rotation A104. The rotating member 104 can thus be trapped or captured between a snap 120a,b (120a shown in FIG. 4) of the holding member 102, which can be a lever arm, and the first end 106 of the holding member 102, allowing the rotating member 104 to rotate freely about but not move by any significant amount lengthwise along the longitudinal axis A102 of the holding member 102. The rotating member 104 also can define a radial direction R104 extending from and about the axis of rotation A104.

When assembled as shown, the axis of rotation A104 of the rotating member 104 and the longitudinal axis A102 of the holding member 102 can be aligned or made coextensive, or nearly so, allowing the user to hold onto the holding member 102 while the film roll 902 and the rotating member 104 turn, allowing the material 910 to be dispensed. It should be noted that some clearance can be provided between the holding member 102 and the rotating member 104 in both the radial and longitudinal directions so that that the rotating member 104 can freely rotate. The amount of clearance can range from, for example and without limitation, 0.005 to 0.025 inches on a side.

Also shown in FIG. 1, the holding member 102 can comprise a brake portion 302, a rail 124, and a connecting portion 320 connecting the brake portion 302 and the rail 124. In one aspect, a transition portion 322 can join the rail 124 and the connecting portion 320. In another aspect, the rail 124 and the connecting portion 320 can be joined directly to one another. The brake portion can at least in part be defined by a slot 308. The first end 106 of the holding member 102 can define an exterior holding surface 122. A one of the first end 106 and the second end 108 of the holding member 102 can define an interior holding surface 300, which more specifically can be defined on a back side of the rail 124. The holding member 102 can be configured such that a portion of the palm of the hand of a user as well as a portion of the thumb as desired can be placed against the exterior holding surface 122 while the interior of the fingers can be placed against the interior holding surface 300 (as shown in FIG. 14B). Thus, the holding member 102 can provide an ergonomic handle for the user to hold onto as the film dispenser 100 is used to dispense the material 910. The interior holding surface 300 can comprise a concave surface facing the longitudinal axis A102 of the holding member 102.

As shown, the first end 106 of the holding member 102 can comprise a handle 200 comprising a plurality of lobes 202a,b,c,d. Each of the plurality of lobes 202a,b,c,d can extend outward in a radial direction along the radial direction R102 of the holding member 102. Each of the plurality of lobes 202a,b,c,d can be positioned between an outside extremity 304 and an inside extremity 306 of the holding member 102 along a direction of the longitudinal axis A102. In one aspect, the holding member 102 can comprise four lobes 202a,b,c,d. In another aspect, the holding member 102 can comprise only one, two, or three lobes 202. In yet another aspect, the holding member 102 can comprise more than four lobes 202. As shown in FIG. 7, each of the plurality of lobes 202 can extend outward beyond a radially outermost edge of the rotating member 104 relative to the longitudinal axis A102. A handle edge 402 can be defined by an intersection between the exterior holding surface 122 and the inside extremity 306 of the holding member 102.

The holding member 102 can further comprise a plurality of web portions 206a,b,c,d. Each web portion 206a,b,c,d can extend between a pair of adjacent lobes 202a,b,c,d of the plurality of lobes 202a,b,c,d. In one aspect, the holding member 102 can comprise four web portion 206a,b,c,d. In another aspect, the holding member 102 can comprise only one, two, or three web portions 206; or the holding member 102 can comprise more than four web portions 206. As shown, the web portions 206a,b,c,d can together define a round or circular, cylindrical, or other shape that is concentric with the longitudinal axis A102. As shown in FIG. 7, each of the plurality of web portions 206 can extend outward beyond a radially outermost edge of the rotating member 104 relative to the longitudinal axis A102. In one aspect, the number of lobes 202 can be equal to the number of web portions 206.

In one aspect, the first end 106 of the holding member 102 can comprise a blend 126, which can be a chamfered or radiused edge, extending along a portion of the circumference or a full circumference of a central hole 128 of the holding member 102. The blend 126 can help provide a lead-in as a user inserts a hand into the central hole 128 for grasping onto or gripping the holding member 102.

FIG. 2 shows the holding member 102 without the rotating member 104 and from a different perspective than shown in FIG. 1. The snap 120a, which can be diametrically opposite from the snap 120b as shown in FIG. 3, is shown in FIG. 2. Each of the snaps 120a,b can be defined by a slot 310a,b (310b shown in FIG. 3) and can be configured to flex radially inward along the radial direction R102 of the holding member 102 when the second end 108 of the holding member 102 is inserted into the rotating member 104. More specifically, each of the snaps 120a,b can define a snap diameter of D120 (shown in FIG. 6), and each of the snaps 120a,b can be configured to flex radially inward along the radial direction R102 of the holding member 102 from a diameter value greater than a diameter D108 (shown in FIG. 4) of the second end 108 to a diameter value less than or equal to the diameter D108.

Each of the snaps 120a,b can comprise a first snap side surface 334a,b (334b shown in FIG. 12), a second snap side surface 335a,b (335a shown in FIG. 3, 335b shown in FIG. 11), and a snap end surface 336a,b (336a shown in FIG. 4; 336b shown in FIG. 3). Each snap 120a,b can comprise a ramp surface 312a,b (both shown in FIG. 4), which can be angled with respect to the longitudinal direction A102 to provide a camming motion to the snap 120a,b as it is inserted into the rotating member 104 until an outside circumferential surface 314a,b (shown in FIG. 3) of each respective snap 120a,b faces the inside surface of the rotating member 104 (as shown in FIGS. 7 and 8) and each snap 120a,b clears the rotating member 104 and “snaps” back. Each of the snaps 120a,b can comprise a catch surface 316a,b (316b shown in FIG. 3), which can be substantially flat and can face in a direction toward the inside of the holding member 102 along the longitudinal axis A102. Each of the snaps 120a,b can be positioned proximate to an outside extremity 318 of the second end 108 of the holding member 102.

As shown in FIG. 3, the holding member 102 can comprise a wall defining a wall thickness 400 that can vary within prescribed ranges. In one aspect, the wall thickness 400 can range from 0.045 to 0.085 inches but more specifically can average about 0.065 inches. In another aspect, the wall thickness 400 can vary outside of this range. In one aspect, each of the holding member 102 and the rotating member 104 can comprise a wall maintaining a consistent wall thickness 400, particularly if each is formed from plastic using an injection molding process. In such a case, it can be advantageous to maintain a consistent wall thickness 400 to avoid potential processing defects such as sink marks or voids. The general design rule is that the variation in the wall thickness of an injection-molded part should be between ±15% to ±25% depending on the shrinkage factor of the material. In another aspect, these components can be made of other suitable materials using other suitable processes, in which case a consistent wall thickness is not necessary.

The outside extremity 304 can be spaced away from the inside extremity 306 or surface, which defines the portion of the first end 106 of the holding member 102 that is nearest the second end 108 of the holding member 102, by a distance L122. In one aspect, the distance L122 can be at least 0.250 inches.

In yet another aspect, the exterior holding surface 122 can be of sufficient length L122 along the longitudinal axis A102 of the holding member 102 that the rotating film roll 902 and the material 910 that is wrapped around the film roll 902 are spaced away from the hand of the user by a desired distance. Increasing this distance can protect the hand from the film roll 902 as the film roll 902 rotates during the film dispensing process. In this aspect, this distance can be as much as 0.75 inches or more, but it is contemplated that the distance could be less, including the aforementioned 0.250 inch for reasons explained later herein. In one aspect, this distance is equal to the length L122 of the exterior holding surface 122, but it is contemplated that the distance could be split into a portion that includes the length L122 of the exterior holding surface 122 and another distance that separates the first end 106 of the holding member 102 from the first end 110 of the rotating member 104 as would be the case if another stop member or flange was added to the holding member 102 and spaced therefrom along the longitudinal axis A102 for contacting the annular flange 118 of the rotating member 104. A gap distance 950 (shown in FIG. 14B) can separate the inside extremity 306 of the holding member 102 from the film roll 902.

A front side of the brake portion 302 of the holding member 102 can be seen in its entirety in FIG. 3. The brake portion 302 can be formed by a cutout in the wall of the second end 108 of the holding member 102 and specifically by the slot 308. The slot 308 can comprise three radial portions 308a, 308b, 308c that can extend in the radial direction R102 of the holding member 102 from an interior surface that defines the hole 128 of the holding member 102 defining an inner diameter D128 (shown in FIG. 5) to the exterior surface 116 defining the outer diameter D108 of the holding member 102. Each of the inner diameter D128 and the outer diameter D108 are measured in a plane that is perpendicular to the longitudinal direction A102 of the holding member 102. The radial portions 308a,b,c can also be described as extending in the circumferential direction around the longitudinal axis A102 of the holding member 102. The first radial portion 308a of these radial slot portions can define a topmost extent of the brake portion 302 and can be defined in the holding member 102 at or proximate to the intersection of the first and second ends 106,108 of the holding member 102 and can extend completely across and above the brake portion 302. Each of the second radial portion 308b and the third radial portion 308c can be positioned distal from the first radial portion 308a along the longitudinal axis A102. The second radial portion 308b and the third radial portion 308c can extend partially across the brake portion 302 on either side of the brake portion 302 near or proximate to where the brake portion connects to the wall of the second end 108 of the holding member 102. The slot 308 can also comprise two longitudinal portions 308d,e that extend in the longitudinal direction A102 and connect the first radial portion 308a with the second radial portion 308b and the third radial portion 308c, respectively.

As will be described below, the slot 308 can provide the brake portion 302 with enough flexibility so that it can be made to move and contact the rotating member 104 when it is desired to tense the film or other material 910 being unrolled by the film dispenser 100. The brake portion 302 can thus be configured to engage the rotating member 104. In one aspect, a width of the slot 308 can vary from 0.05 to 0.125 inches. In another aspect, widths outside of this range are contemplated. The slot 308 can define two longitudinal extending exterior surfaces 330a,330b and three radial extending exterior surfaces 332a,b,c of the brake portion 302. In one aspect, as shown, a longitudinal center axis A302 and a radial center axis A303 of the brake portion 302 can be positioned halfway circumferentially between the lobe 202c and the lobe 202d of the handle 200 of the holding member 102. In such an arrangement, the longitudinal center axis A302 and the radial center axis A303 of the brake portion 302 can be positioned halfway circumferentially between any pair of a plurality of radial centerlines 602a,b,c,d (shown in FIG. 5). In another aspect, the longitudinal center axis A302 and the radial center axis A303 of the brake portion 302 can be positioned anywhere circumferentially between any pair of adjacent lobes 202a,b,c,d relative to the longitudinal axis A102. In another aspect, the longitudinal center axis A302 and the radial center axis A303 of the brake portion 302 can be made to intersect or can be substantially aligned with any of the plurality of the radial centerlines 602a,b,c,d.

As shown in FIG. 4, the snap 120a can be defined by the slot 310a. Each of the snaps 120a,b can comprise a first longitudinal portions 411a, a second longitudinal portion 412a, and a radial or circumferential portion 413a. The circumferential portion 413a is so named because it extends in a circumferential direction around the longitudinal axis A102 of the holding member 102. A distance L102 can be measured from the inside extremity 306 to the respective catch surfaces 316a,b of the snaps 120a,b. As mentioned above and will be described in more detail herein, the overall length of the rotating member 104 can be less than the distance from the inside extremity 306 of the first end 106 of the holding member 102 to the catch surface 316 of the snap 120a,b, as measured in a direction that is parallel to the longitudinal axis A102 of the holding member 102. It is contemplated that the number, placement, and configuration of the snaps may be altered in various aspects of the present disclosure. For example and without limitation, more than two snaps 120 or only a single snap 120 may be used as well as other variations.

As shown in FIGS. 5 and 6, the plurality of lobes 202a,b,c,d of the holding member 102 can define an overall lobe diameter D202 and the radial centerlines 602a,b,c,d, respectively. Likewise, the plurality of web portions 206a,b,c,d of the holding member 102 can define a web portion diameter D206 and a web portion radius R122 (shown in FIG. 6). Also, each of the plurality of lobes 202a,b,c,d can define portions that extend radially outward past the plurality of web portions 206,a,b,c,d and can define a variable distance R502 measured in a radial direction from the longitudinal axis A102 of the holding member 102 to the handle edge 402. The distance R502 can be greater at the radial centerlines 602a,b,c,d than at an angular position that is not aligned with the radial centerlines 602,a,b,c,d. Each of the plurality of lobes 202a,b,c,d can define a convex or rounded portion 511a,b,c,d extending along each respective radial centerline 602a,b,c,d, whereas the exterior holding surface 122 can define a concave or recessed portion 512a,b,c,d extending between adjacent rounded portions 511a,b,c,d. Each of the rounded portions 511a,b,c,d and the recessed portions 512a,b,c,d can be smoothly shaped, including with a constant radius as desired, to facilitate an ergonomic grip by the user. An intersection between adjoining pairs of each of the rounded portion 511a,b,c,d and each of the recessed portion 512a,b,c,d can comprise an inflection point or an inflection curve at which point or along which curve a center of a radius of the surface or edge on the handle changes position—for example and without limitation, from a center outside the handle for the recessed portions 512a,b,c,d to a center outside the handle for the rounded portions 511a,b,c,d, at least as viewed from the perspective of FIGS. 5 and 6. Although any one of a number of different shapes could accomplish this including the shape of the holding member 102 as shown, each lobe 202a,b,c,d, and in particular the rounded portions 511a,b,c,d and the recessed portions 512a,b,c,d can be designed to ergonomically fit the shape of the hand of the user depending on whether the brake portion 302 is positioned between adjacent lobes 202a,b,c,d or in another position instead.

As shown, in one aspect, the interior holding surface 300 can comprise a concave surface facing the longitudinal axis A102 of the holding member 102 and defining a radius of curvature R300. In other aspects, the interior holding surface 300 be flat or convex. In one aspect, a center of the radius of curvature R300 can be offset from the longitudinal axis A102 radially outward toward the exterior of the holding member 102 and in such case is not coincident with the longitudinal axis A102 of the holding member 102 or concentric with the central hole 128.

As shown in FIG. 6, the holding member 102 can comprise a plurality of stops 910a,b,c,d, each of which can be a rib or a gusset or flange, extending radially outward from an outer surface 702 of a cylindrical portion 700 of the holding member 102 and axially inward from an inner surface 201 of the handle 200. In one aspect, as shown in FIGS. 7 and 8, each of the stops 910a,b,c,d can extend in a longitudinal direction from the inner surface 201 of the handle 200 to the inside extremity 306, which as shown can also be where the first end 106 and the second end 108 intersect. In another aspect, each of the stops 910a,b,c,d can extend in a longitudinal direction past the inside extremity 306. In one aspect, when the rotating member 104 slides towards the first end of the holding member 102, the stops 910a,b,c,d can be configured to contact the rotating member 104 of the film dispenser 100 axially at or outward from the inside extremity 306 relative to the longitudinal axis A102 to prevent the film roll 902 and the rotating member 104 from contacting or sliding underneath the lobes 202a,b,c,d and the web portions 206a,b,c,d of the first end 106.

Opposing stops of the plurality of stops 910a,b,c,d can define a stop diameter D910. By making the stop diameter D910 greater than a diameter D628 (shown in FIG. 9) of a central hole 628 (also shown in FIG. 9) of the rotating member 104, an axial end of each of the stops 910a,b,c,d can be made to contact the annular flange 118 of the rotating member 104. By contacting the annular flange 118 of the rotating member 104, the holding member 102 can be held at a desired distance relative to the rotating member 104. At each position of the stops 910a,b,c,d, the holding member 102 can comprise a pair of stops 910a,b,c,d. By increasing the number of stops 910a,b,c,d, an axial load each stop 910a,b,c,d and the stresses (including mechanical stress and heat) experienced inside each stop 910a,b,c,d can be kept at a minimum. In one aspect, each of the stops 910a,b,c,d can be centered between adjacent radial centerlines 602a,b,c,d. In another aspect, the stops 910a,b,c,d can be positioned in a different circumferential position. In yet another aspect, additional stops or fewer stops can be used.

As shown in FIG. 7, the rotating member 104 can define an overall length L104.

As shown in FIG. 8, each of the lobes 202a,b,c,d can comprise a blend 1202, which can define a blend radius R1202, and each of the web portions 206a,b,c,d can comprise a blend 1206, which can define a blend radius R1206. Either of the blend radius R1202 or the blend radius R1206 can be decreased or increased from that shown. In one aspect, as shown, the blend 1202 and the blend 1206 can define less than a full radius (i.e., the blend 1202 and the blend 1206 can be sized to not fill or cover the entire outside edge of the handle 200 between the outside extremity 304 and the inside extremity 306). In another aspect, the blend 1202 and the blend 1206 can define a full radius along at least a portion of the handle 200 for a different look and/or feel. Also as shown, an edge—or a plurality of edges—of the annular flange 118 of the rotating member 104 can comprise a blend defining a blend radius R118. In yet another aspect, either the blend 1202 or the blend 1206 can vary around the perimeter of the handle 200 or can otherwise have a more complex shape that is not necessarily constant in radius or even curved.

In one aspect, as shown, a diameter D118 of the annular flange 118 can be less than the diameter D206 defined by the web portions 206a,b,c,d. This construction can help keep the rotating annular flange 118 away from the user's hand during use of the film dispenser 100.

Also as shown in FIG. 8, portions of the rail 124 and interior holding surface 300 can be considered to be part of the first end 106 of the holding member 102, even though portions of each directly extend from the second end 108 and are otherwise not connected directly to other portions of the first end 106 of the holding member 102. In one aspect, because the rail 124 and its interior holding surface 300 can be connected to the brake portion 302 by the transition portion 322 and the connecting portion 320 of the second end 108 of the holding member 102, the rail 124 and its interior holding surface 300 can thereby be operatively associated with the brake portion 302, as any force directed in an outward direction along the radius R102 of the holding member 102 against the rail 124 moves the brake portion 302. In another aspect, this operative association can be achieved in other ways such as, for example and without limitation, by having the rail 124 connected directly to the brake portion 302. Also, the rail 124 and the interior holding surface 300 can both be incorporated into the second end 108 of the holding member 102 by positioning both below the intersection of the first end 106 and the second end 108 of the holding member 102, which coincides with an edge of the slot 308a defining in part the brake portion 302.

FIGS. 9 and 10 show the detailed structure of the rotating member 104, which as noted above can define a substantially annular or tubular shape and can comprise the features noted. The first end 110 can comprise an abutment portion in the form of the annular flange 118. The annular flange 118 can define a wall thickness 610 measured in the direction of the axis of rotation A104 and a wall thickness 620 (shown in FIG. 10) measured along the radial direction R104 of the rotating member 104. The second end 108 can comprise a tube or sleeve portion such as the sleeve 115, which can comprise the cylindrical exterior surface 116 with the ribs 114. The ribs can be configured to engage the inside of the film roll 902 in a frictionally desirable manner, helping to keep the film roll 902 from falling off the film dispenser 100. The cross section of one of the ribs 114 can comprise a semi-circular shape. For example and without limitation, each of the ribs can define an outside radius of 0.156 inches when looking at a cross-section taken along the radial direction R104 of the rotating member 104. In one aspect, ends 624a-j (shown in FIG. 12) of the ribs 114 adjacent to an outside extremity 626 of the second end 112 of the rotating member 104 can be angled at 45 degrees from the axis of rotation A104, providing a lead-in for inserting the rotating member 104 into the film roll 902. In another aspect, the ends 624a-j of the ribs 114 adjacent to an outside extremity 626 of the second end 112 of the rotating member 104 can be angled at more than 45 degrees or less than 45 degrees from the axis of rotation A104. Either of the wall thicknesses 610,620 of the rotating member 104 can vary from 0.045 to 0.085 inches and can average 0.65 inches. Again, the rotating member 104 can measure the overall length L104.

The central hole 628 of the rotating member 104 can define a diameter D628 and can be sized to receive the second end 108 of the holding member 102. Specifically, the diameter D628 of the central hole 628 can be made slightly greater than the outside diameter D108 (shown in FIG. 4) of the second end 108 of the holding member 102. A blend 630 can be defined at the entry of the central hole 628 proximate to the first end 110 of the rotating member 104 to provide a lead-in for inserting the holding member 102 into the rotating member 104. The outer diameter D118 of the annular flange 118 can be substantially the same as the outer diameter D206 of the first end 106 of the holding member 102. It is contemplated that the dimensions associated with various features of the rotating member 104 can be changed to adapt to a smaller or larger film roll 902 and a smaller or larger holding member 102.

FIGS. 11, 12, and 13 show further how the holding member 102 and the rotating member 104 can be assembled and how the film dispenser 100 can be coupled to the film roll 902. First, the rotating member 104 can be inserted into an opening defined in an end of the film roll 902 until its abutment portion or the annular flange 118 of the first end 110 contacts the end of the film roll 902. At this point, the ridges or ribs 114 can be completely enveloped in or received within the film roll 902 and can be configured to frictionally hold the rotating member 104 inside the film roll 902 (as shown in FIG. 13). Next, the second end 108 of the holding member 102 can be inserted into the central hole 628 of the rotating member 104. As the holding member 102 is inserted into the rotating member 104, the snaps 120a,b can be pushed radially inward by the sleeve 115 of the rotating member 104 until the second end 108 of the holding member 102 extends past the second end 112 of the rotating member 104, at which time the snaps 120a,b can be configured to “snap” back and return to their original position and the catch surfaces 316a,b of the snaps 120a,b can capture the outside extremity 626 of the second end 112 of the rotating member 104. At about the same time, in one aspect, the annular flange 118 can contact or nearly contact the inside extremity 306 of the first end 106 of the holding member 102. In other aspects, the annular flange 118 can contact the stops 901a,b,c,d of the holding member 102 with the inside extremity 306 or before the annular flange 118 contacts the inside extremity 306. In either aspect, the first end 106 of the holding member 102 can be spaced away or offset from an edge of the material 910 that is dispensed from the film roll 902 during dispensing. Because the overall length L104 of the rotating member 104 can be less than the distance L102 from the inside extremity 306 to the catch surfaces 316a,b of the snaps 120a,b (as shown in FIG. 7), the rotating member 104 can fit between the snaps 102a,b and the inside extremity 306 of the first end 106 of the holding member 102.

As shown in FIG. 12, the stops 910a,b,c,d (910a and 910b shown in FIG. 6) can prevent the rotating member 104, and the annular flange 118 in particular, from riding up inside the handle 200 or inside the first end 106 of the holding member 102.

FIG. 13 shows the film roll 902, rotating member 104, and holding member 102 in a completely assembled state. In one aspect, the rotating member 104 can be held in place relative to the film roll 902 by friction alone. The rotating member 104 can be held inside the film roll 902 be an interference fit between the rotating member 104—and specifically the ribs 114 (shown in FIG. 1)—that can cause the ribs 114 to dig into and bear against the walls of the core of the film roll 902.

In another aspect, the rotating member 104 is held in place with an adhesive placed in a radial gap 1300 defined between the rotating member 104 and the film roll 902. In various aspects, the film dispenser 100 can be removable from the film roll 902, though in other aspects the film dispenser 100 may not be removable from the film roll 902.

As shown in FIG. 14A, the aforementioned process of assembling the film dispenser 100 can be repeated at the other end of the film roll 902 so that two film dispensers 100a,b (shown in FIG. 14A) are positioned at opposite ends of the film roll 902. The user can then use the film dispensers 100a,b to unroll the material 910 from the film roll 902. FIGS. 14A through 14C show how the film dispenser 100 can be used to dispense the material 910 and how a film dispenser 100 can be held in the hand of the user.

FIG. 14B in particular show how, for example and without limitation, a film dispenser 100 can fit into the hand of the user, allowing the fingers to fit within the central hole 128 of the holding member 102 and the thumb and a portion of the palm to be placed on the exterior holding surface 122 of the holding member 102. As the material 910 is being dispensed, a clenching of the hand will cause the brake portion 302 of the holding member 102 to move radially outward and impinge on the rotating member 104, causing the rotating member 104 to slow down or stop rotating altogether, causing tensioning or even stretching of the film as the user continues to move the film roll 902 about the item to be wrapped or covered, all as has been previously described.

As shown in FIG. 14C, a holding member 102 can be installed in the film roll 902 without a rotating member 104. In order to fit and function properly, the diameter D108 of the holding member 102 can be increased so that clenching of the hand about the holding member 102 to engage the brake portion 302 causes the brake portion 302 to move radially outward and impinge on an inner bore of the film roll 902, causing the film roll 902 to slow down or stop rotating altogether, causing tensioning or even stretching of the material 910 as the user continues to move the film roll 902 about the item to be wrapped or covered. With or without use of the rotating member 104, any surface of the holding member, the rotating member 104, or the inner bore of the film roll 902 can be roughened or textured or supplemented with an additional polymeric or other material (held in place, for example and without limitation, by adhesive or by an overmolding process) to increase the friction between adjacent components and in particular, for example and without limitation, increase the grip of the brake portion 302 against the surface it is configured to slow down or stop.

The slots 308 that can define the brake portion 302 and the slots 310 that can define the snaps 120a,b can result in “undercuts” on the part to be considered when a molding or casting process is used to make the holding member 102. As a result of these undercuts, a “side action” or multiple side actions can be used to form these structures as the holding member 102 is being molded. These side actions can then retracted, allowing the ejection of the holding member 102 from the mold. For example and without limitation, each of two side actions can be used to make one snap 120 and half of the slots 308 that define the brake portion 302. With such a design, the side actions would move in a direction that is perpendicular to the longitudinal axis A102 and parallel to the radial direction R102.

The brake portion 302 can be operatively associated with the rail 124 and the interior holding surface 300. Movement of the brake portion 302 relative to the other portions of the holding member 102 can be made possible by the slot 308 defined in the holding member 102, which can be defined in the second end 108. More specifically, if sufficient force is exerted by the fingers of a user, the brake portion 302 can be deflected outwardly along the radial direction R102 of the holding member 102 until the brake portion 302 contacts the rotating member 104, creating enough friction to stop or at least retard the rotation of the rotating member 104. Because the rotating member 104 is held tight inside an inner bore of the film roll 902 by, for example and without limitation, friction or an adhesive material between the rotating member 104 and the film roll 902, stopping or retarding the motion of the rotating member 104 can stop or retard the motion of the film roll 902. This, in turn, can cause any stretch wrap or film being dispensed to be tensed and, to the degree desired, stretched a certain amount. When these effects are no longer desired, the user simply releases the brake portion 302 by removing enough force from the interior holding surface 300 of the rail 124 so that the brake portion 302 springs back inwardly along the radial direction R102 of the holding member 102 and no longer contacts the rotating member 104. Although the operative association between the rotating member 104 and the brake portion 302 may be direct, such as when the brake portion 302 is able to engage the rotating member 104 directly or contact it directly, the operative association may also be indirect as may be the case when other components are found between the brake portion 302 and the rotating member 104.

As desired, the length of the rail 124 in the direction of the longitudinal axis A102 including a lever distance 801 (shown in FIG. 8) measured from an axial end 805 (shown in FIG. 8) of the rail 124 to where the connecting portion 320 intersects with the brake portion 302 or a lever distance 802 (also shown in FIG. 8) measured to the point where the brake portion 302 contacts the rotating member 104 or the inside bore of the film roll 902 can be adjusted to increase or decrease the amount of leverage created by the hand of the user or to adjust the ergonomic feel of the holding member 102 in the hand of the user. For example and without limitation, increasing a distance from where the hand contacts the rail to where the connecting portion 320 intersects with the brake portion 302 or where the brake portion 302 contacts the rotating member 104 or the inside bore of the film roll 902 can reduce the amount of force required to engage the brake portion 302 and thereby slow the rotating member 104 and/or the film roll 902.

As mentioned above with respect to FIG. 1, the first end 106 of the holding member 102 can comprise the blend 126 for guiding the insertion of a hand into the central hole 128 of the holding member 102. Once a hand is positioned inside the holding member 102, it can press onto the interior holding surface 300 found on the rail 124 that is operatively associated with the brake portion 302 of the holding member 102. An example of how this operative association can be created will now be explained with reference to FIGS. 2 and 11. As already stated, the top radial portion of the slot 308a that defines the brake portion 302 can be positioned at the division of the holding member 102 into its first and second ends 106, 108 (see FIG. 4). Therefore, any structure found above this top longitudinal portion of the slot 308a can be considered part of the first end 106 of the holding member 102. As already explained, the connecting portion 320 can be located toward the interior of the holding member 102 along the longitudinal axis A102 and away from the outside extremity 304 of the first end 106 of the holding member 102, the connecting portion 320 extending in a plane that is perpendicular to the longitudinal axis A102 of the holding member 102. Also, the connecting portion 320 or member can be located below the top radial portion of the slot 308a and can extends in an inner radial direction R102 toward the rail 124, which can extend above the top radial portion of the slot 308a. The transition portion 322 can connect or attach the connecting portion 320 to the rail 124 and its associated interior holding surface 300 and can be angled with respect to the longitudinal direction A102 and with respect to the connecting portion 320 as shown in FIG. 8. The connecting portion 320 can be located toward an interior of the holding member 102 along the longitudinal axis A102 and away from an outside extremity 304 of the first end 106 of the holding member 102. The connecting portion 320 can extend radially inward from any portion of the brake portion 302 and can extend in a plane that is angled with respect to the longitudinal axis A102 of the holding member 102.

A method of dispensing the material 910 from the film roll 902 using the film dispenser 100 can comprise holding onto the interior holding surface 300 and the exterior holding surface 122 of a holding member 102 of the film dispenser 100 with one hand such that a portion of the hand is positioned between a pair of the adjacent lobes 202a,b,c,d of the plurality of lobes 202a,b,c,d of the holding member 102, the holding member 102 comprising the first end 106 comprising the interior holding surface 300 and the plurality of lobes 202a,b,c,d defining the exterior holding surface 122; and the second end 108 comprising a brake portion 302; wherein the second end 108 of the holding member 102 is inserted into an opening defined in the first end of the film roll 902; dispensing the material 910 by rotating the film roll 902 relative to the holding member 102; and pressing onto the brake portion 302 to increase the tension in the material 910 being dispensed. The method of pressing onto the brake portion 302 can comprise contacting a rotating member 104 of the film dispenser 100 with the brake portion 302 to create friction between the brake portion 302 and the rotating member 104 of the film dispenser 100. The method can further comprise preventing movement of a one of the film roll 902 and a rotating member 104 of the film dispenser 100 past an intersection of the first end 106 and the second end 108 of the holding member 102.

It should be noted that any of the steps of any of the methods described herein may be performed in any order or could be performed in sub-steps that are done in any order or that are separated in time from each other by other steps or sub-steps. Similarly, the steps of inserting the holding member 102 into the rotating member 104 and inserting the rotating member 104 into the film roll 902 can be done in any order as both effectuate the same end result, that is to say, the film dispenser 100 is operatively engaged with the film roll 902. The same principle can be applied to any step of any method disclosed herein. Additional steps may also be added. For example and without limitation, the holding member 102 can be assembled to the rotating member 104 before both are inserted into the film roll 902.

The assembly configurations described herein represent some of many possible assembly configurations. One skilled in the art will understand obvious variations of this assembly configuration are included within this disclosure, including variations of steps, combinations of steps, and dissections of steps, among others. Where materials are chosen for the elements of this assembly—particularly, rubber, metal, and plastic—similar material choices may also be used and would be obvious to one in the art. The rotating member 104 and/or the holding member 102 may be made of cast iron, steel, aluminum, titanium, copper, brass, various plastics, polymers, resins, or any material. In one aspect, the rotating member 104 and/or the holding member 102 can be made of a material of sufficient strength to withstand the loads placed on them when the material 910 or other materials from the film roll 902 and yet be resilient enough to allow snapping of the holding member 102 and the rotating member 104 together as well as movement of the brake portion 302. In another aspect, the brake portion 302 and/or the snaps 120a,b can be formed separately from and assembled to the holding member 102. It is contemplated that many of the features that have been described herein as being part of either the holding member 102 or the rotating member 104 could be switched to the other of the holding member 102 or the rotating member 104 including the snaps 120a,b and that features found completely in one member could be split in some cases between the two members. Furthermore, the configuration of either member need not be annular but could be otherwise depending on the application. Finally, additional members may be added to the film dispenser 100 and various components may be split into other components. For example, an elastomeric component may be applied to the handle portion of the holding member 102 or the surface texture of the holding member 102 otherwise configured to aid in grip and ergonomics. In such a case, the elastomeric component could be considered a portion of the holding member 102. This elastomeric component could be added to a plastic holding member 102 using two-shot molding or overmolding technology or by other methods known or that will be devised in the art.

The material 910 can be formed from any conceivable stretchable or non-stretchable material including, for example, film, foil, cloth, paper, or a polymer material such as linear low-density polyethylene (LLDPE) or polyvinyl chloride (PVC). It is not uncommon for a stretchable material such as these to be stretched between 100% and 500% or more of its original length during use. The film dispenser can be used for any use including, for example and without limitation, any commercial or residential application requiring the wrapping or covering of an item with a material 910 such as the aforementioned stretch wrap film.

One should note that conditional language, such as, among others, “can,” “could,” “might,” or “may,” unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain aspects comprise, while other aspects do not comprise, certain features, elements and/or steps. Thus, such conditional language is not generally intended to imply that features, elements and/or steps are in any way required for one or more particular aspects or that one or more particular aspects necessarily comprise logic for deciding, with or without user input or prompting, whether these features, elements and/or steps are included or are to be performed in any particular aspect.

It should be emphasized that the above-described aspects are merely possible examples of implementations, merely set forth for a clear understanding of the principles of the present disclosure. Any process descriptions or blocks in flow diagrams should be understood as representing modules, segments, or portions of code which comprise one or more executable instructions for implementing specific logical functions or steps in the process, and alternate implementations are included in which functions may not be included or executed at all, may be executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved, as would be understood by those reasonably skilled in the art of the present disclosure. Many variations and modifications may be made to the above-described aspect(s) without departing substantially from the spirit and principles of the present disclosure. Further, the scope of the present disclosure is intended to cover any and all combinations and sub-combinations of all elements, features, and aspects discussed above. All such modifications and variations are intended to be included herein within the scope of the present disclosure, and all possible claims to individual aspects or combinations of elements or steps are intended to be supported by the present disclosure.

Various implementations described in the present disclosure may include additional systems, methods, features, and advantages, which may not necessarily be expressly disclosed herein but will be apparent to one of ordinary skill in the art upon examination of the following detailed description and accompanying drawings. It is intended that all such systems, methods, features, and advantages be included within the present disclosure and protected by the accompanying claims.
