One aspect of the disclosure provides an assembly. The assembly includes a cylindrical sleeve and a length of material that is wound upon itself defining a wound roll. The cylindrical sleeve includes an inner surface and an outer surface. The inner surface of the cylindrical sleeve defines a passage extending through the cylindrical sleeve. The length of material includes an inner surface and an outer surface. A portion of the inner surface of the length of material forms a passage extending through the wound roll. The outer surface of the cylindrical sleeve is secured to the portion of the inner surface of the length of material that forms the passage extending through the wound roll. At least a portion of the inner surface of the cylindrical sleeve is defined by a Sheffield Smoothness that is less than 350.

In some implementations, the Sheffield Smoothness defined by the inner surface of the cylindrical sleeve is approximately equal to 250.

In some examples, the length of material is a length of wrapping film.

In some instances, the passage extends through the cylindrical sleeve between a distal end of the cylindrical sleeve and a proximal end of the cylindrical sleeve. Access to the passage is permitted by a distal opening formed in the distal end of the cylindrical sleeve and a proximal opening formed in the proximal end of the cylindrical sleeve.

In some implementations, the cylindrical sleeve is defined by a body. The body is defined by a thickness extending between the inner surface and the outer surface.

In some examples, the body is defined by one or more materials.

In some instances, the body includes two materials defined by: a first material and a second material.

Some of the plurality of impregnations are entirely contained within the cylindrical body formed by the first material. Some of the plurality of impregnations are not entirely contained within the cylindrical body formed by the first material and thereby defines a plurality of inner surface portions and a plurality of outer surface portions. The plurality of inner surface portions define at least a second portion of the inner surface of the cylindrical sleeve. The plurality of outer surface portions define at least a second portion of the outer surface of the cylindrical sleeve.

In some examples, the second material defining at least the second portion of the inner surface of the cylindrical sleeve is defined by the Sheffield Smoothness that is less than 350. The first material has a Sheffield Smoothness that is greater than 350.

DETAILED DESCRIPTION OF THE INVENTION

The Figures illustrate exemplary embodiments of a cylindrical sleeve and a method for utilizing the same. Based on the foregoing, it is to be generally understood that the nomenclature used herein is simply for convenience and the terms used to describe the invention should be given the broadest meaning by one of ordinary skill in the art.

Referring to FIGS. 1A-1B, an assembly is shown generally at 10. The assembly includes a cylindrical sleeve 12 (see, e.g., FIGS. 2A and 3A), 12′ (see, e.g., FIGS. 2B and 3B), 12″ (see, e.g., FIGS. 2C and 3C) or 12′″ (see, e.g., FIGS. 2D and 3D) and wound roll 14. A length of material, F, that is wound upon itself may define the wound roll 14.

In some implementations, the length of material, F, may be a length of wrapping film. As seen in FIG. 4, the length of wrapping film, F, may be dispensed/unwound from the wound roll 14 by a user, U, such that the length of wrapping film, F, may be disposed about and wrap a plurality of goods, G, that are arranged upon a pallet, P. Although some implementations of the length of material, F, may include a length of wrapping film, the length of material, F, may not be limited to including a length of wrapping film, and may alternatively include, for example, a length of paper, a length of tin foil or the like.

Referring back to FIGS. 1A-1B, the cylindrical sleeve 12, 12′, 12″, 12′″ may include an inner surface 16, 16′, 16″, 16′″ and an outer surface 18, 18′, 18″, 18′″. The cylindrical sleeve 12, 12′, 12″, 12′″ is defined by a body 20, 20′, 20″, 20′″ of one or more materials (e.g., one material as seen in FIGS. 2C and 3C, or, alternatively, a first material 20a (see, e.g., FIGS. 2A and 3A), 20a′ (see, e.g., FIGS. 2B and 3B), 20a′″ (see, e.g., FIGS. 2D and 3D) and a second material 20b (see, e.g., FIGS. 2A and 3A), 20b′ (see, e.g., FIGS. 2B and 3B), 20b′″ (see, e.g., FIGS. 2D and 3D)). The body 20, 20′, 20″, 20′″ is defined by a thickness, 20_T, 20_T′, 20_T″, 20_T″, 20_T′″ extending between the inner surface 16, 16′, 16″, 16′″ and the outer surface 18, 18′, 18″, 18′″.

The inner surface 16, 16′, 16″, 16′″ defines a passage 22, 22′, 22″, 22′″ extending through the cylindrical sleeve 12, 12′, 12″, 12′″ between a distal end 24, 24′, 24″, 24′″ of the cylindrical sleeve 12, 12′, 12″, 12′″ and a proximal end 26, 26′, 26″, 26′″ of the cylindrical sleeve 12, 12′, 12″, 12′″. Access to the passage 22, 22′, 22″, 22′″ is permitted by a distal opening 28, 28′, 28″, 28′″ formed in the distal end 24, 24′, 24″, 24′″ of the cylindrical sleeve 12, 12′, 12″, 12′″ and a proximal opening 30, 30′, 30″, 30′″ formed in the proximal end 26, 26′, 26″, 26′″ of the cylindrical sleeve 12, 12′, 12″, 12′″.

The length of material, F, includes an inner surface, F_I, and an outer surface, F_O. A portion of the inner surface, F_I, of the length of material, F, forms a passage 32 extending through the wound roll 14. The outer surface 18, 18′, 18″, 18′″ of the cylindrical sleeve 12, 12′, 12″, 12′″ may be secured to the portion of the inner surface, F_I, of the length of material, F, that forms the passage 32 extending through the wound roll 14. In some implementations, an adhesive (not shown) may be disposed over one or both of the outer surface 18, 18′, 18″, 18′″ of the cylindrical sleeve 12, 12′, 12″, 12′″ and the portion of the inner surface, F_I, of the length of material, F, that forms the passage 32 extending through the wound roll 14 for securing the cylindrical sleeve 12, 12′, 12″, 12′″ to the wound roll 14.

Referring to FIGS. 2A and 3A, the exemplary cylindrical sleeve 12 is shown. Referring to FIG. 3A, the body 20 defining the cylindrical sleeve 12 includes at least a first material 20a and a second material 20b.

The first material 20a may include a cylindrical body having an inner surface 20a_I and an outer surface 20a_O. The outer surface 20a_O of the first material 20a may define the outer surface 18 of the cylindrical sleeve 12. The second material 20b may include a cylindrical body having an inner surface 20b_I and an outer surface 20b_O. The inner surface 20b_I of the second material 20b may define the inner surface 16 of the cylindrical sleeve 12. The inner surface 20a_I of the first material 20a is disposed adjacent the outer surface 20b_O of the second material 20b.

In some implementations, the second material 20b is a liner that is disposed over the inner surface 20a_I of the first material 20a. In some examples, the outer surface 20b_O of the second material 20b is secured to the inner surface 20a_I of the first material 20a by an adhesive (not shown).

In some implementations, the first material 20a may include a rough, cardboard-based paper material that includes, but is not limited to a new/virgin paper material or a recycled paper material. In some examples, the second material 20b may include a paper material (e.g., a paper lining including a plush characteristic, such as velvet). In some instances, the second material 20b may include a non-paper material (e.g., a plastic lining). Although the first material 20a of FIG. 2A, which may include a rough, cardboard-based paper material, is shown including one layer of material, the first material 20a is not limited to including one layer of material; accordingly, in some instances, the first material 20a, which may include a rough, cardboard-based paper material, may include a plurality of layers of material. In some examples, a multi-layer first material 20a may be formed by winding a strip of rough, cardboard-based paper material (e.g., Brown Kraft paper, which may alternatively be referred to as recycled paper) on a mandrel in a spiral with edges of the rough, cardboard-based paper material arranged adjacent one another forming a spiral seam; subsequently, one or more second strips of rough, cardboard-based paper material may be wound over the first rough, cardboard-based paper material arranged upon the mandrel until the first material 20a is formed to include a desired thickness. In some instances, if, for example, the rough, cardboard-based paper material paper is 0.025″ thick, and, a desired thickness of the first material 20a is 0.25″, ten strips of rough, cardboard-based paper material may be utilized as described above for forming the first material 20a.

Comparatively, a Sheffield Smoothness (SS) of the second material 20b is lower than a SS of the first material 20a; in some implementations, the first material 20a may be defined by a SS greater than 350 (e.g., a SS that is approximately equal to 370). In some implementations, the second material 20b may be defined by a SS that is less than 350; in an exemplary embodiment, the second material 20b may be defined by a SS approximately equal to 250.

As a result of the SS of the second material 20b being less than the SS of the first material 20a, the inner surface 20b_I of the second material 20b is defined by a SS that is less than a SS of the inner surface 20a_I of the first material 20a. Therefore, because the inner surface 20b_I of the second material 20b defines the inner surface 16 of the cylindrical sleeve 12, the inner surface 16 of the cylindrical sleeve 12 includes a lower SS than, for example a rough, cardboard-based paper material.

Although FIGS. 2A-3A show a first material 20a and a second material 20b, the cylindrical sleeve 12 is not limited to a first material 20a and a second material 20b. For example a cylindrical sleeve 12″″ (see, e.g., FIGS. 2E and 3E) may include a first material (see, e.g., 20a″″ in FIG. 3E), a second material (see, e.g., 20b″″ in FIG. 3E) and a third material (see, e.g., 20c″″ in FIG. 3E). The third material 20c″″ may be arranged over and adjacent the outer surface 20a_O″″ of the first material 20a″″. A Sheffield Smoothness (SS) of the third material 20c″″ is lower than a SS of the first material 20a″″; in some implementations, the first material 20a″″ may be defined by a SS greater than 350 (e.g., a SS that is approximately equal to 370). In some implementations, the second and third materials 20b″″, 20c″″ may be defined by a SS that is less than 350; in an exemplary embodiment, the second and third materials 20b″″, 20c″″ may be defined by a SS approximately equal to 250.

Referring to FIGS. 2B and 3B, the exemplary cylindrical sleeve 12′ is shown. The body 20′ defining the cylindrical sleeve 12′ includes at least a first material 20a′ and a second material 20b′.

The first material 20a′ may include a cylindrical body having an inner surface 20a_I′ and an outer surface 20a_O′. The outer surface 20a_O′ of the first material 20a′ may define the outer surface 18′ of the cylindrical sleeve 12′. The second material 20b′ may include a cylindrical body having an inner surface 20b_I′ and an outer surface 20b_O′. The inner surface 20b_I′ of the second material 20b′ may define the inner surface 16′ of the cylindrical sleeve 12′. The inner surface 20a_I′ of the first material 20a′ is disposed adjacent the outer surface 20b_O′ of the second material 20b′.

In some implementations, the second material 20b′ is a coating that is disposed over the inner surface 20a_I′ of the first material 20a′. If the second material 20b′ is a coating, in some instances, at the time the second material 20b′ is applied (e.g., extruded, lapped, painted or the like) to the first material 20a′, the outer surface 20b_O′ of the second material 20b′ may include a tacky, adhesive quality that permits the outer surface 20b_O′ of the second material 20b′ to bond to the inner surface 20a_I′ of the first material 20a′ without the use of a binding agent (e.g., such as, for example, an adhesive). Once the second material 20b′ has cured, the tacky, adhesive quality of the second material 20b′ may define a smooth, non-tacky, non-adhesive quality.

In some implementations, the first material 20a′ may include a rough, cardboard-based paper material that includes, but is not limited to a new/virgin paper material or a recycled paper material. In some instances, the second material 20b′ may include a non-paper material (e.g., a plastic coating). Although the first material 20a′ of FIG. 2B, which may include a rough, cardboard-based paper material, is shown including one layer of material, the first material 20a′ is not limited to including one layer of material; accordingly, in some instances, the first material 20a′, which may include a rough, cardboard-based paper material, may include a plurality of layers of material. In some examples, a multi-layer first material 20a′ may be formed by winding a strip of rough, cardboard-based paper material (e.g., Brown Kraft paper, which may alternatively be referred to as recycled paper) on a mandrel in a spiral with edges of the rough, cardboard-based paper material arranged adjacent one another forming a spiral seam; subsequently, one or more second strips of rough, cardboard-based paper material may be wound over the first rough, cardboard-based paper material arranged upon the mandrel until the first material 20a′ is formed to include a desired thickness. In some instances, if, for example, the rough, cardboard-based paper material paper is 0.025″ thick, and, a desired thickness of the first material 20a′ is 0.25″, ten strips of rough, cardboard-based paper material may be utilized as described above for forming the first material 20a′.

Comparatively, a Sheffield Smoothness (SS) of the second material 20b′ is lower than a SS of the first material 20a′; in some implementations, the first material 20a′ may be defined by a SS greater than 350 (e.g., a SS that is approximately equal to 370). In some implementations, the second material 20b′ may be defined by a SS that is less than 350; in an exemplary embodiment, the second material 20b′ may be defined by a SS approximately equal to 250.

As a result of the SS of the second material 20b′ being less than the SS of the first material 20a′, the inner surface 20b_I′ of the second material 20b′ is defined by a SS that is less than a SS of the inner surface 20a_I′ of the first material 20a′. Therefore, because the inner surface 20b_I′ of the second material 20b′ defines the inner surface 16′ of the cylindrical sleeve 12′, the inner surface 16′ of the cylindrical sleeve 12′ includes a lower SS than, for example a rough, cardboard-based paper material.

Although FIGS. 2B-3B show a first material 20a′ and a second material 20b′, the cylindrical sleeve 12′ is not limited to a first material 20a′ and a second material 20b′. For example a cylindrical sleeve 12″″ (see, e.g., FIGS. 2E and 3E) may include a first material (see, e.g., 20a″″ in FIG. 3E), a second material (see, e.g., 20c″″ in FIG. 3E) and a third material (see, e.g., 20c″″ in FIG. 3E). The third material 20c″″ may be arranged over and adjacent the outer surface 20a_O″″ of the first material 20a″″. A Sheffield Smoothness (SS) of the third material 20c″″ is lower than a SS of the first material 20a″″; in some implementations, the first material 20a″″ may be defined by a SS greater than 350 (e.g., a SS that is approximately equal to 370). In some implementations, the second and third materials 20b″″, 20c″″ may be defined by a SS that is less than 350; in an exemplary embodiment, the second and third materials 20b″″, 20c″″ may be defined by a SS approximately equal to 250.

Referring to FIGS. 2C and 3C, the exemplary cylindrical sleeve 12″ is shown. Unlike the exemplary cylindrical sleeves 12, 12′ described above, the body 20″ of the exemplary cylindrical sleeve 12″ does not include two materials (e.g., 20a, 20b as seen in FIG. 3A or 20a′, 20b′ as seen in FIG. 3B), but, rather, one material. The body 20″ may include a cylindrical body having an outer surface 20_O″ and an inner surface 20_I″.

The body 20″ is not composed of a rough, cardboard-based paper material. In some instances, the body 20″ may include a non-cardboard-based paper material (e.g., a plastic material); hereinafter, the body 20″ is referred to as a non-cardboard-based body. The non-cardboard-based body 20″ may be formed, for example, in an injection molding procedure.

Comparatively, a Sheffield Smoothness (SS) of the non-cardboard-based body 20″ is lower than a SS of a cardboard-based paper material. In some implementations, a cardboard-based paper material may be defined by a SS greater than 350 (e.g., a SS that is approximately equal to 370). In some implementations, the non-cardboard-based body 20″ may be defined by a SS that is less than 350; in an exemplary embodiment, the non-cardboard-based body 20″ may be defined by a SS approximately equal to 250.

As a result of the SS of the non-cardboard-based body 20″ being less than the SS of a cardboard-based paper material, the inner surface 20_I″ of the non-cardboard-based body 20″ is defined by a SS that is less than a SS of a cardboard-based paper material. Therefore, because the inner surface 20_I″ of non-cardboard-based body 20″ defines the inner surface 16″ of the cylindrical sleeve 12″, the inner surface 16″ of the cylindrical sleeve 12″ includes a lower SS than, for example a rough, cardboard-based paper material.

Referring to FIGS. 2D and 3D, the exemplary cylindrical sleeve 12′″ is shown. The body 20′″ defining the cylindrical sleeve 12′″ includes at least a first material 20a″″ and a second material 20b′″.

The first material 20a′″ may include a cylindrical body having an inner surface 20a_I′″ and an outer surface 20a_O′″. The outer surface 20a_O′″ of the first material 20a′″ may define at least a portion of the outer surface 18′″ of the cylindrical sleeve 12′″ and at least a portion of the inner surface 16′″ of the cylindrical sleeve 12′″. The second material 20b′″ may include a plurality of impregnations that are disposed throughout the cylindrical body of the first material 20a′″. Therefore, when the impregnations defining the second material 20b′″ are entirely contained within the cylindrical body of the first material 20a′″, in some instances, the second material 20b′″ does not form an inner surface or outer surface that contributes to any of the inner surface 16′″ or the outer surface 18′″ of the cylindrical sleeve 12′″; however, when the impregnations defining the second material 20b′″ are not entirely contained within the cylindrical body of the first material 20a′″, in some instances, the second material 20b′″ may serially form a plurality of inner surface portions 20b_I′″ and a plurality of outer surface portions 20b_O′″ that defines at least a portion of the outer surface 18′″ of the cylindrical sleeve 12′″ and at least a portion of the inner surface 16′″ of the cylindrical sleeve 12′″.

In some implementations, the first material 20a′″ may include a rough, cardboard-based paper material that includes, but is not limited to a new/virgin paper material or a recycled paper material. In some instances, the second material 20b′″ may include a hardwood material. Although the first material 20a′″ of FIG. 2D, which may include a rough, cardboard-based paper material, is shown including one layer of material, the first material 20a′″ is not limited to including one layer of material; accordingly, in some instances, the first material 20a′″, which may include a rough, cardboard-based paper material, may include a plurality of layers of material. In some examples, a multi-layer first material 20a′″ may be formed by winding a strip of rough, cardboard-based paper material (e.g., Brown Kraft paper, which may alternatively be referred to as recycled paper) on a mandrel in a spiral with edges of the rough, cardboard-based paper material arranged adjacent one another forming a spiral seam; subsequently, one or more second strips of rough, cardboard-based paper material may be wound over the first rough, cardboard-based paper material arranged upon the mandrel until the first material 20a′″ is formed to include a desired thickness. In some instances, if, for example, the rough, cardboard-based paper material paper is 0.025″ thick, and, a desired thickness of the first material 20a′″ is 0.25″, ten strips of rough, cardboard-based paper material may be utilized as described above for forming the first material 20a′″.

Comparatively, a Sheffield Smoothness (SS) of the second material 20b′″ is lower than a SS of the first material 20a′″; in some implementations, the first material 20a′″ may be defined by a SS greater than 350 (e.g., a SS that is approximately equal to 370). In some implementations, the second material 20b′″ may be defined by a SS that is less than 350; in an exemplary embodiment, the second material 20b′″ may be defined by a SS approximately equal to 250.

As a result of the SS of the second material 20b′″ being less than the SS of the first material 20a′″, the plurality of inner surface portions 20b_I′″ of the second material 20b′″ (that defines at least a portion of the inner surface 16′″ of the cylindrical sleeve 12′″) is defined by a SS that is less than a SS of the inner surface 20a_I′″ of the first material 20a′″ (that also defines at least a portion of the inner surface 16′″ of the cylindrical sleeve 12′″). Therefore, because the plurality of inner surface portions 20b_I′″ of the second material 20b′″ defines at least a portion of the inner surface 16′″ of the cylindrical sleeve 12′″, the second material 20b′″ reduces the SS of the inner surface 16′″ of the cylindrical sleeve 12′″ that is at least partially defined by the first material 20a′″ including, for example a rough, cardboard-based paper material.

Referring to FIG. 4, because the inner surface 16, 16′, 16″, 16′″ of the cylindrical sleeve 12, 12′, 12″, 12′″ is defined by a lower SS in comparison to, for example, a rough, cardboard-based paper material, a user, U, may insert his/her hands, H, directly into the passage 22, 22′, 22″, 22′″ extending through the cylindrical sleeve 12, 12′, 12″, 12′″ such that one or more of the user's, U, hands, H, may be in direct contact with the inner surface 16, 16′, 16″, 16′″ of the cylindrical sleeve 12, 12′, 12″, 12′″ when the wound roll 14 spins about an axis of rotation, A-A, as the length of wrapping film, F, is dispensed/unwound from the wound roll 14 due to the lower SS of the inner surface 16, 16′, 16″, 16′″ of the cylindrical sleeve 12, 12′, 12″, 12′″ promoting increased comfort to the user's, U, hands, H, in comparison to, for example, a cylindrical sleeve that consists only of, for example, a rough, cardboard-based paper material. Further, because the inner surface 16, 16′, 16″, 16′″ of the cylindrical sleeve 12, 12′, 12″, 12′″ is defined by a lower SS in comparison to, for example, a rough, cardboard-based paper material, the assembly 10 obviates use of gloves for the user's, U, hands, H, due to the increased comfort imparted to the user's, U, hands, H. Even further, because the inner surface 16, 16′, 16″, 16′″ of the cylindrical sleeve 12, 12′, 12″, 12′″ is defined by a lower SS in comparison to, for example, a rough, cardboard-based paper material, the assembly 10 obviates use of an axial insert, which may include, for example, hand grips, that would otherwise be inserted into the passage 22, 22′, 22″, 22′″ extending through the cylindrical sleeve 12, 12′, 12″, 12′″ due to the increased comfort imparted to the user's, U, hands, H, as described above. Yet even further, although the cylindrical sleeve 12, 12′, 12″, 12′″ and the wound roll 14 illustrated in FIG. 1B are shown having substantially aligned or substantially flush axial ends, some implementations of the assembly 10 may include portions 12_LP-1, 12_LP-2 (see, e.g., FIG. 5C) of the cylindrical sleeve 12, 12′, 12″, 12′″ that extend beyond axial ends 34, 36 (see, e.g., FIG. 5C) of the wound roll 14. In some instances, as seen in, for example, FIGS. 5A-5C, the cylindrical sleeve 12, 12′, 12″, 12′″ may include a length 12_L that is greater than a length 14_L of the wound roll 14; accordingly, when the cylindrical sleeve 12, 12′, 12″, 12′″ is disposed within the passage 32 extending through the wound roll 14, a first portion 12_LP-1 of the length 12_L of the cylindrical sleeve 12, 12′, 12″, 12′″ may extend beyond an upper axial end 34 of the would roll 14 and a second portion 12_LP-2 of the length 12_L of the cylindrical sleeve 12, 12′, 12″, 12′″ may extend beyond a lower axial end 36 of the would roll 14. Such implementations may permit a user to grasp the outer surface 18, 18′, 18″, 18′″ of the portions 12_LP-1, 12_LP-2 of the length 12_L of the cylindrical sleeve 12, 12′, 12″, 12′″. In such implementations, a portion of the outer surface 18, 18′, 18″, 18′″ of the cylindrical sleeve 12, 12′, 12″, 12′″ may formed in a manner to define a lower SS in comparison to, for example, a rough, cardboard-based paper material in a substantially similar as described above with respect to the inner surface 16, 16′, 16″, 16′″ of the cylindrical sleeve 12, 12′, 12″, 12′″. In addition, some implementations of the assembly 10 may also include axial ends of the cylindrical sleeve 12, 12′, 12″, 12′″ (that connect the inner surface 16, 16′, 16″, 16′″ to the outer surface 18, 18′, 18″, 18′″) that define a lower SS in comparison to, for example, a rough, cardboard-based paper material.

A number of implementations have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the disclosure. Accordingly, other implementations are within the scope of the following claims. For example, the actions recited in the claims can be performed in a different order and still achieve desirable results.
