[0039] Referring generally to the FIGURES, an insulating holder for a beverage container includes a sleeve made of a foam material. The sleeve is configured to slide around the outer surface of the beverage container and is also configured to be reusable.

[0040] Referring to FIG. 1, a combination 1 of a beverage container (e.g., cup, etc.) 10 and a sleeve 20 is shown. The beverage container 10 may be any commercially available beverage container which is used to provide hot beverages to consumers by beverage providers. For example, the beverage container 10 includes a top, open end 11 which includes a lip and a closed, bottom end 12. The beverage container 10 may have a slight taper to it, that is, a size of a diameter of the closed, bottom end 12 may be slightly less than a size of a diameter of the top, open end 11 of the beverage container 10. The beverage container 10 also includes an outer surface 13 and an inner surface (not shown) in which the beverage is contained within the beverage container 10.

[0041] As shown in FIGS. 1 and 4, the combination 1 also includes a sleeve 20. The sleeve 20 is configured to be inserted around the outer surface 13 of the beverage container 10. The sleeve 20 is also configured to be held by a hand 60 of a user. Accordingly, the sleeve 20 is sized appropriate so that it will fit securely around the outer surface 13 of the beverage container 10 in a middle portion of the beverage container 10. According to one aspect, the sleeve 20 is configured to slide along the outer surface 13 of the beverage container 10 from the closed, bottom end 12 of the beverage container 10 towards the top, open end 11 of the beverage container 10 until the sleeve 20 fits snugly in place in the middle portion of the outer surface 13.

[0042] As shown in FIG. 2-3, the sleeve 20 includes a top side 21 and a bottom side 22. The sleeve 20 also includes an inner surface (e.g., back surface) 24 and an outer surface (e.g., front surface) 25 which, according to one example, include a plurality of pin holes 30 distributed across the outer surface 25. The sleeve 20 also includes a first end 26 and a second end 27. The sleeve 20 is manufactured as a thin sheet and the first end 26 and the second end 27 are securably attached to each other (e.g., joined together) by any suitable means. For example, the first end 26 and the second end 27 are securably attached to each other by applying low heat and thereby melting a portion of the first end 26 and a portion of the second end 27 together. Accordingly, a firm seal that is difficult to break can be obtained. Accordingly, the sleeve 20 has approximately a conical shape and has a circular cross-sectional area. The sleeve 20 is configured to be shipped either as a flat sheet or as a sleeve.

[0043] The sleeve 20 is of any suitable size. According to one aspect, the first end 26 and the second end 27 have a same width which is the same width as a middle portion of the sleeve 20. As a specific example, the first end 26 and the second end 27 are about 3 inches in width. According to one aspect, the top side 21 of the sleeve 20 is about 10 inches in length. According to one aspect, the bottom side 22 of the sleeve 20 is about 8.5 inches in length. According to one aspect, the width of the sleeve 20 is about 0.125 inches.

[0044] As shown in FIG. 3, the sleeve 20 is made of a single layer of foam. However, the sleeve 20 is not limited to this particular implementation. For example, the sleeve 20 may be made of multiple layers of foam.

[0045] The sleeve 20 is configured to provide insulation and thereby reduce and/or prevent a risk of burning the hand 60 of the user when the user is holding the beverage container 10 holding a hot beverage. Accordingly, the sleeve 20 is made of a foam material. Although any suitable foam material may be used for the sleeve 20, the sleeve 20 may be made of polyethylene, for example low density polyethylene (LDPE). As an additional example, the sleeve 20 may be made of polyurethane which is an open cell foam which offers excellent resilience and durability and is available in a wide variety of densities and colors. Additionally, polyurethane exhibits good cushioning, and moisture absorption properties.

[0046] Accordingly, the sleeve 20 has good insulation properties due to the relatively low heat conductivity of the foam. The unique pin hole properties of the foam (due to the presence of the plurality of pin holes 30 in the sleeve 20) reduce a rate of heat transfer through the foam. Additionally, the sleeve 20 is lightweight because of the low weight of the foam, thereby reducing freight and shipping costs of the sleeve 20.

[0047] As one example, the foam has insulation properties which allow the sleeve 20 to reduce and/or prevent a rate of heat transfer between the inner surface 24 and the outer surface 25. More specifically, when a hot liquid having a temperature within a range of 200 and 212 degrees Fahrenheit (for example, 205 degrees Fahrenheit) is placed in the beverage container 10, the sleeve 20 on the outer surface 13 reduces a rate of heat transfer from the inner surface 24 to the outer surface 25. For example, the sleeve 20 is configured to reduce the rate of heat transfer from the inner surface 24 to the outer surface 25 such that the temperature at the outer surface 25 of the sleeve 20 is just above the body temperature of the user. As a specific example, the sleeve 20 is configured to reduce the rate of heat transfer such that the temperature at the outer surface 25 of the sleeve 20 is not greater than about 100 degrees Fahrenheit. As another specific example, the sleeve 20 is configured to reduce the rate of heat transfer such that the temperature at the outer surface 25 of the sleeve 20 is about 99 degrees Fahrenheit. Accordingly, unlike conventional cup holders made of corrugated paper, the sleeve 20 does not absorb heat but rather reduces or prevents heat conduction through the sleeve 20.

[0048] Another desirable property of the sleeve 20 is its durability due to the foam which can survive repeated washing (for example, washing by hand, etc.). The durability allows the sleeve to be used multiple times rather than only a single time like the prior art corrugated paper cup holders. Additionally, a used sleeve 20 can be stored in a pocket or purse of a user after use. Alternatively, a used sleeve 20 can be rolled up or squeezed into different orientations and will return to its usable orientation shown in FIG. 2 due to the mechanical elasticity of the foam material.

[0049] Yet another desirable property of the sleeve 20 is that it does not require glue to stay in place on the beverage container 10. Because of the friction between the outer surface 13 of the beverage container 10 and the foam of the sleeve 20, the sleeve 20 will remain in position on the beverage container 10 without requiring adjustment by a user.

[0050] Yet another desirable property of the foam of the sleeve 20 is that it can be recycled after use without causing increased greenhouse gas emissions during the recycling process. When the foam is recycled, it is useable as a material for a carpet pad, rebond material, or the foam may be shredded and used as stuffing filler for a variety of applications.
