Benefits of technology
"The invention is a beverage container made of polystyrene foam covered with a paperboard wrapping. The foam provides insulation and is comfortable for holding hot beverages. The paperboard wrapping allows for high-quality printing and can be used for promotional items like coupons or stickers. The method involves shrinking the foam cup and applying the paperwrap with adhesive, followed by adding promotional items to the paperwrap. The technical effect is a beverage container that is easy to hold and promotional items can be added easily."
Problems solved by technology
Paperboard cups, however, tend to be poor insulators of heat.
A paperboard cup containing a hot beverage, therefore, may be difficult to hold.
The exterior surface of a polystyrene foam cup, however, typically does not provide for high-quality printing.
Also, polystyrene foam cups are typically not as suitable for the attachment of promotional items as are paperboard cups.

Embodiment Construction
[0014]FIGS. 1A-1D depict an example embodiment of a method according to the invention for manufacturing a beverage container. As shown in FIG. 1A, a first end 112 of a paper wrap 120 may be placed on a cup body 105 and held in place. The cup body 105 may be made of polystyrene foam, such as expanded polystyrene (EPS), for example. The paper wrap 120 may be made of paperboard, such as solid bleached sulfate (SBS) paperboard, for example. The SBS paperboard may have a clay coating that provides a smooth finish onto which high quality printing may be presented on the finished cup 100. The paperboard may have a thickness of between about eight and about fourteen mils. The paper wrap may have a smooth surface for the display of printed material. Alternatively, the paper wrap may be scored or ridged to provide additional slip resistance for a user holding a cup, for example, or for decorative or other purposes.
[0015] As shown in FIG. 1B, the paper wrap 120 may be wrapped around the cup b...

A beverage container having a polystyrene foam cup body wrapped in a paper covering is disclosed. The paper-wrapped polystyrene foam beverage container may provide thermal insulation while simultaneously providing a means to display high quality printed matter to the user. A method of making the paper wrapped polystyrene foam cups includes providing a polystyrene foam cup body that has been allowed to shrink to its stable proportions and thereafter applying the paper wrap. A promotional item may be attached to the paper wrap.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The subject matter disclosed and claimed herein is related to the subject matter disclosed in U.S. patent application no. [attorney docket RHC-0009], filed Dec. 17, 2004, entitled “Paper-Wrapped Polymer Beverage Container.” The disclosure of the above-referenced U.S. patent application is incorporated herein by reference in its entirety.FIELD OF THE INVENTION [0002] Generally, the invention relates to beverage containers. More particularly, the invention relates to paper-wrapped, expanded polystyrene beverage containers. BACKGROUND OF THE INVENTION [0003] Disposable hot-beverage containers, such as coffee cups, for example, are typically made of paperboard or polystyrene foam. Paperboard cups may be desirable for a number of reasons. For example, a paperboard cup may provide a high-quality printable surface from the lip of the cup to its base. Also, paperboard cups tend to be suitable for the attachment of promotional items, such as det...
