Hot and cold beverages and food (e.g., coffee, tea, soft drinks, soup, ice cream, and the like) may present a handling problem to consumers when dispensed into containers such as drinking cups. For example, paper, plastic, and foam drinking cups often do not provide sufficient thermal insulating properties when filled with hot or cold beverages. As a result, handling of such containers may be uncomfortable to the consumer.
A sleeve is disclosed with a unique wave-like shape. Sleeves are sometimes used to supplement the thermal insulating properties of containers by, for example, reducing the rate of heat transfer between a container and a hand gripping the container.
The sleeve may encircle a container and provide comfortable handling of hot or cold containers. The sleeve may provide protection approximating that of sleeves not having the wave-like shape while using less manufacturing materials and may thus reduce the environmental impact of sleeve manufacturing.
Other systems, methods, features and advantages of the invention will be, or will become, apparent to one with skill in the art upon examination of the following figures and detailed description. It is intended that all such additional systems, methods, features and advantages be included within this description, be within the scope of the invention, and be protected by the following claims.
A sleeve for use with a container is disclosed. When placed on a container the sleeve may provide a thermal barrier between the container and a hand of a user. The thermal barrier may protect the user's hand from the temperature of the container. Alternatively or additionally, the thermal barrier may decrease heat transfer across the wall of the container and may thereby maintain the temperature of the container contents.
The sleeve may have a wave-like shape of peaks and troughs. The shape of the peaks and troughs may be, for example, square, arcuate, circular, or triangular, or any other shape. The width of the sleeve from peak to trough approximates the width, for example, of at least two fingers of human hand, and the shape may accommodate placing a thumb and at least two fingers on the sleeve. The sleeve may be sized to fit an adult or child container.
The wave-like shape of the sleeve may use reduced sheet material as compare to sleeves without a wave-like shape. Reducing the amount of sheet material used in manufacturing sleeves may cause waste reduction, which may be better for the environment.
Further, the wave-like shape of the sleeve may be more efficient to manufacture than sleeves which adapt to the shape of a conical cup by the expansion of slits, notches, honeycomb structures, or otherwise. For example, the wave-like shape may reduce the complexity of the die-cutting or other manufacturing processes.
A sleeve 10 may be positioned in combination with a container 12 as in
The sleeve 10 may be assembled with the container 12 where the sleeve 10 fully encircles the circumference of the container 12. The sleeve 10 may be manufactured of, for example, paperboard, cardboard, plastic, foam, cellulosic fiber, wood, or any other materials. The sleeve 10 may also be coated internally or externally with, for example, heat-sensitive glues, printing, water proof material, and etc.
The sleeve 10 may include a first edge 18 and a second edge 20, which may be the top and bottom of the sleeve, or vice versa. The first edge 18 and second edge 20 may have a series of peaks 24 and troughs 22. The peaks 24 and troughs 22 may give the sleeve 10 a wave-like shape. Alternatively, the shape of the peaks 24 and troughs 22 may be, for example, square, or triangular, or any other shape. The peaks 24 and troughs 22 may be parallel to each other and may facilitate manufacturing ease and efficiency.
In
The wave-like shape of the sleeve 10 may provide superior comfort and insulation over other sleeve designs, for example, sleeve designs which conform to a cup by expansion of a number of slits, notches, a honeycomb structure or otherwise. Sleeves that rely on expansion of slits may leave gaps in which the sleeve does not cover the container. These gaps may reduce comfort and insulation by leaving exposed areas of the container. Furthermore, a sleeve relying only upon slits, notches, or honeycombed structures, by virtue of leaving exposed areas of the container, may have reduced ability to maintain the temperature of the container contents. The wave-like shape of the sleeve 10 may provide a balance between material reduction and maintenance of thermal properties.
In
The sleeve 10 may be converted from collapsed form to uncollapsed form by, for example, pushing inward on the fold lines 32 and 34. The uncollapsed form of the sleeve 10 may define an opening through which a container 12 may be inserted.
In a first embodiment, the first edge 18 of the blank 40 of the sleeve 10 may have at least two peaks 24 and one trough 22 relative to the second edge 20. In a second embodiment, the second edge 20 of the blank 40 of the sleeve 10 may have at least two peaks 24 and one trough 22 relative to the first edge 18. In a third embodiment, the peaks 24 of the first edge 18 may correspond to the troughs 22 of the second edge 20. In a fourth embodiment, the peaks 24 of the second 20 edge may correspond to the troughs 22 of the first edge 18. In a fifth embodiment, the peaks 24 and troughs 22 may create a generally s-shape wave. In a sixth embodiment, the peaks 24 and troughs 22 may be parallel. More or less peak 24 and troughs 22 may be used.
The wave-like shape may facilitate ease in manufacturing. There only need be one cut line between the sleeves, with no material lost between the sleeves as there may be no gaps between the unseparated sleeves. The wave-like shape may reduce the amount of source material consumed during manufacturing while maintaining similar handling protection to sleeves without the wave-like shape. Material reduction may reduce the environmental impact of sleeve manufacturing. Material reduction may also reduce the costs of production.
Either surface 46 or 48 of the sleeve 10 may be, for example but not limited to, smooth, fluted, corrugated, embossed, debossed, printed, waxed, and/or lined with foam, plastic, paper, glue, or any other material.
The blank of the sleeve 10 may have, for example but not limited to, a length 50 of approximately 9.5-11 inches. Alternatively, the length of the blank of the sleeve 10 may be dimensioned for a child-size container, an over-sized container, or any other size or shaped container. The blank of the sleeve 10 may have, for example but not limited to, a height 52 of approximately 1.8-2.5 inches. Alternatively, the height of the blank of the sleeve 10 may be dimensioned for a child-size container, an over-sized container, or any other sized or shaped container. The height 52 of the blank of the sleeve 10 may remain constant or may vary over its length 50.
Sheet material may contain one or more blanks 40 of a sleeve 10. The blanks 40 may be positioned on the sheet material in a repeating pattern such that the top and bottom edge portions of each sleeve shares a cut line such that there is not gaps between the sleeves.
The blanks 64 of the sleeves without the wave-like shape may have a height 68 of, for example but not limited to, 1.8-2.5 inches. The blanks 64 of the sleeves without the wave-like shape may have a length of, for example but not limited to, 9.5-11 inches.
While various embodiments of the invention have been described, it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible that are within the scope of the invention.
