BACKGROUND OF THE INVENTION1. Field of the Invention
This invention relates generally to accessories for beverage containers and, more specifically, to a Combination Cup Sleeve and Plug Assembly.
2. Description of Related Art
Boutique coffee shops (and large chain coffee shops) have grown exponentially in popularity. As with many growing industries, the growth of the coffee shop industry has resulted in the introduction of many new products related to the core product (i.e. coffee). One particularly popular product that has experienced significant evolutionary steps as a result of the popularity of the coffee shop industry is that of the disposable cup.
A common design for the disposable beverage container 10 used by coffee shops today has a container 10 made from cardboard or other paper-related product. For safety to prevent spilling, there is a disposable lid 12 that snaps onto a lip formed at the upper rim of the container 10. The lid 12 is defined by an upper lid rim 14 and a lower lid rim 16; the lower rim 16 has a groove formed in it that cooperates with the lip formed in the rim of the container 10. A dispensing aperture 18 is disposed on the top of the upper lid rim 14. This aperture 18 is typically rectangular in shape with rounded corners (at least for one or two particularly large chain coffee shop company's product). Because the coffee products provided to the consumer in these containers 10 is typically very hot, even to the touch, a very useful accessory was developed—the insulating sleeve 20.
While these sleeves 20 can come in a variety of different materials and styles, one predominant style is depicted in
These disposable insulating sleeves 20 are very effective at their functional purpose, but they are lacking in at least two areas—aesthetic appeal and spill prevention. While the user's hand is well protected against burns from the hot cup 10, there is nothing to prevent the user from spilling coffee out of the aperture 18 (which typically does not have a cover). What is needed, then is a device or assembly that not only protects the user's hand against burns from heat transfer through the wall of the container 10, but also provides a way to prevent spilling out through the aperture 18. It would also be very beneficial if this device or assembly was designed and made from materials that made it more aesthetically pleasing than the prior sleeves 20. Also, most sleeves are designed from low-cost materials (either paper or cardboard) to meet a disposability objective. It would be beneficial if there were a sleeve that incorporated a higher quality material in order to improve aesthetics, provide reusability, as well as potentially providing superior thermal insulating qualities.
SUMMARY OF THE INVENTIONIn light of the aforementioned problems associated with the prior devices and assemblies, it is an object of the present invention to provide a Combination Cup Sleeve and Plug Assembly. The combination should include an insulating sleeve for disposable beverage containers, as well as a detachable plug for the dispensing aperture formed in the lid of the container and a lanyard interconnecting the two. The sleeve should be provided in a variety of durable, aesthetically pleasing, non-disposable forms. The plug should be configured to be insertible into the dispensing aperture of the cup and should be made either from semi-precious or low cost materials. The plug should further have a surface for displaying trademarks and/or identifying indicia thereon. The sleeve should further include a holder for the plug when the plug is not in use for plugging the dispensing aperture. The lanyard should be a detachable member (from the plug) made from cord, chain or other material that will interconnect the plug and the sleeve.
BRIEF DESCRIPTION OF THE DRAWINGSThe objects and features of the present invention, which are believed to be novel, are set forth with particularity in the appended claims. The present invention, both as to its organization and manner of operation, together with further objects and advantages, may best be understood by reference to the following description, taken in connection with the accompanying drawings, of which:
The following description is provided to enable any person skilled in the art to make and use the invention and sets forth the best modes contemplated by the inventor of carrying out his invention. Various modifications, however, will remain readily apparent to those skilled in the art, since the generic principles of the present invention have been defined herein specifically to provide a Combination Cup Sleeve and Plug Assembly.
The present invention can best be understood by initial consideration of
Extending from the front side of the sleeve 32 is an additional storage sleeve or pocket, referred to herein as the plug pocket 38. The plug pocket 38 is generally made from a flap of the same material as the outer layer 46 attached to the outside of the outer layer 46 in such a way as to form a receptacle for the plug (see
In order to provide added aesthetic appeal, one or more indicia may be engraved or otherwise displayed or etched to the body 56 of the plug 34; in this embodiment, the indicia 68 is inscribed on the back face 62 (opposite the eyelet 48B). One exemplary indicia is that of the coffee shop company's logo or name.
The eyelet 48B is preferably formed as an integral part of the body 56 in order to insure the security of its attachment to the lanyard 36, however, this does not preclude possible manufacturing cost considerations dictating other approaches. The lanyard 36 is shown here as a jewelry-grade chain that interconnects the plug 34 with the sleeve (see
Having completed the review of a first set of embodiments of the present invention, we shall now turn to a second preferred embodiment.
The insulating sleeve 32A of this embodiment has two distinct members, the outer sheath member 102 and the inner sheath member 100. The two members 100 and 102 have individualized physical properties that cause them to function very well together as a “sandwich.” The outer sheath member 102 is configured to be durable and readily able to accept permanent indicia inscriptions, such as by screen printing or other conventional means, while its laminated layers provide additional desired thermal characteristics with respect to radiated thermal energy, which will be elaborated upon in subsequent paragraphs. The inner sheath member 100, is quite different from the outer sheath member in that it's material of construction provides the predominant thermal insulation properties; it will, therefore protect a user's hand from being burned, or scalded by hot liquid held in a cup within the sleeve 32A, while at the same time insulating the hot beverage in order to prolong the duration that the beverage remains at elevated temperatures.
As will be discussed more fully below, the sleeve 32A is made from flat sheet(s) of material that is then formed into a conical shape, with the opposing ends being held together by a resilient fastener 104. The resilient fastener 104 has a plurality of arms 106 extending from it that are configured to slip through slots formed in the sheets making up the insulating sleeve 32A. Once passing through the slots, the arms 106 attach to one another to retain the ends of the inner and outer sheath members 100 and 102 together.
The plug pocket assembly 118 is configured to removably clip onto the insulating sleeve 32A, such that the assembly 118 can be made separately (and potentially from a different material) than the sleeve 32A. The lanyard 36 attaches to the assembly 118 to interconnect the assembly 118 and the plug 34. A pocket 38A is provided by the assembly 118 for storage of the plug 34 as discussed previously within this disclosure. Now turning to
Adjacent to the opposing ends, a plurality of slots 110 are cut through the material of the sheath member 100. As discussed above, the slots 110 are provided to allow the arms of the resilient fastener to pass through for assembly.
The outer sheath member 102 is shaped substantially the same as the inner sheath member 100, such that the outer perimeters and slots 110 align closely with one another when the two sheaths are juxtaposed. The outer sheath 102 is made from material that serves at least two functions: first, it provides a durable outer display layer 108 upon which labeling or other indicia can be imprinted; next, it has an inner radiant thermal-energy barrier layer 106 that inhibits radiant heat transfer. A preferred material choice to provide these features is to employ a vinyl-coated [outer surface] aluminized mylar [inner surface] fabric that has been laminated into a single sheet of material. If possible, in fact, it would be desirable to attach the outer sheath 102 and the inner sheath 100 into a single laminated sheet. The 2-sheath approach can be improved by providing sections of the hook portion of a hook-and-loop fastener material on the inner surface of the outer sheath member 102. These sections of the hook portion of hook-and-loop fastener will actually interlock with the felt material from which the inner sheath member 100 is made to prevent the two layers from easily coming apart or moving independently of one another. We will now turn to
The arms, e.g. 106C and 106F are aligned as pairs so that once arm 106C passes through its corresponding slots in the sheaths, and once arm 106F passes through its associated slots in the other end of the sheaths, the ends of the arms 106C and 106F can fold over one another (see
Those skilled in the art will appreciate that various adaptations and modifications of the just-described preferred embodiment can be configured without departing from the scope and spirit of the invention. Therefore, it is to be understood that, within the scope of the appended claims, the invention may be practiced other than as specifically described herein.
