Definitions
- the invention relates generally to the field of beverage containers. More specifically, the invention relates to thermally-insulating, disposable containers having a body wrapped by a paper wrap.
- 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 detachable coupons, labels, stickers, or game pieces, for example, that vendors frequently use for marketing purposes.
- Paperboard cups tend to be poor insulators of heat. A paperboard cup containing a hot beverage, therefore, may be difficult to hold. To compensate for the lack of insulation provided by a single paperboard cup, a plurality of such cups may be nested together. A separate cardboard wrap may be used to provide insulation, or the cup may include handles.
- Polystyrene foam cups typically provide better thermal insulation than do paperboard cups. Accordingly, polystyrene foam cups tend to be more suitable than paperboard cups for containing hot beverages - at least in terms of thermal insulation. 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.
- Disposable cups made of polymers such as polypropylene provide an alternative to paper cups.
- Polypropylene cups may be more durable, less susceptible to leaks and punctures, and more economical than paper cups.
- Polypropylene is a poor thermal insulator.
- the exterior surface of a polystyrene foam cup typically does not provide for high-quality printing. Further, it is well-known that consumers of high-end hot beverages have come to expect that the beverage will be served in a paperboard cup.
- U.S. Pat. No. 5,716,512 (“Barrett”) discloses a paper-covered polypropylene cup.
- the cup disclosed by Barrett includes a plurality of vertical ribs projecting radially outward from the outer surface of a side wall of a cup. Each of the ribs has an outer face against which a wrap is disposed. The regions encompassed by adjacent, vertical ribs, the interior surface of the wrap, and the outer surface of the side wall may provide for thermally insulating gaps.
- the cup disclosed by Barrett may not provide adequate side wall integrity to prevent side wall deflection when being handled. For example, the side wall may be easily deflected inward, constricting the volume of the container and forcing out the contents of the cup.
- U.S. Pat. No. 6,554,154 (“Chauhan”) discloses a thermoplastic container having a first set of horizontal annular rings disposed adjacent to a top portion of a side wall of the container and a second set of annular rings disposed in a middle portion of the container.
- the annular rings (or “ribs”) increase side wall integrity and improve deflection characteristics over prior art designs.
- the thermoplastic container disclosed by Chauhan may not provide sufficient thermal insulation to serve as a hot-beverage container. Additionally, the container disclosed by Chauhan does not have the desired look and feel of a paper cup, and its exterior surface is not suitable for high-quality printing.
- a beverage container according to the invention may include a polypropylene cup body covered with a paperboard wrapping.
- the cup body may have a bottom and a side wall extending from the bottom.
- the side wall may form an open end opposite the bottom.
- the cup body may have a plurality of annular ribs disposed adjacent to one another circumferentially around the side wall parallel to a plane defined by the bottom of the cup body.
- the paperboard wrapping may be disposed circumferentially around an exterior of the cup body, and may abut at least one of the ribs such that a thermally insulating gap is formed between the cup body and the paper wrap.
- the paperboard wrapping may provide for high quality printing on the entire exterior of the cup. Additionally, the paperboard wrapping may permit the use of attachments such as those a beverage vendor may use as promotional items. Examples of such promotional items include detachable coupons, tear-off labels or stickers, or playing pieces for a game.

Abstract
Description
- The subject matter disclosed and claimed herein is related to the subject matter disclosed and claimed in U.S. patent application Ser. No. [attorney docket RHC-0011], filed Dec. 17, 2004, entitled “Paper-Wrapped Polystyrene Foam Beverage Container.” The disclosure of the above-referenced U.S. patent application is incorporated herein by reference in its entirety.
- The invention relates generally to the field of beverage containers. More specifically, the invention relates to thermally-insulating, disposable containers having a body wrapped by a paper wrap.
- 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 detachable coupons, labels, stickers, or game pieces, for example, that vendors frequently use for marketing purposes.
- Paperboard cups, however, tend to be poor insulators of heat. A paperboard cup containing a hot beverage, therefore, may be difficult to hold. To compensate for the lack of insulation provided by a single paperboard cup, a plurality of such cups may be nested together. A separate cardboard wrap may be used to provide insulation, or the cup may include handles.
- Polystyrene foam cups typically provide better thermal insulation than do paperboard cups. Accordingly, polystyrene foam cups tend to be more suitable than paperboard cups for containing hot beverages - at least in terms of thermal insulation. 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.
- Disposable cups made of polymers such as polypropylene, for example, provide an alternative to paper cups. Polypropylene cups may be more durable, less susceptible to leaks and punctures, and more economical than paper cups. Polypropylene, however, is a poor thermal insulator. Also, the exterior surface of a polystyrene foam cup typically does not provide for high-quality printing. Further, it is well-known that consumers of high-end hot beverages have come to expect that the beverage will be served in a paperboard cup.
- U.S. Pat. No. 5,716,512 (“Barrett”) discloses a paper-covered polypropylene cup. The cup disclosed by Barrett includes a plurality of vertical ribs projecting radially outward from the outer surface of a side wall of a cup. Each of the ribs has an outer face against which a wrap is disposed. The regions encompassed by adjacent, vertical ribs, the interior surface of the wrap, and the outer surface of the side wall may provide for thermally insulating gaps. The cup disclosed by Barrett, however, may not provide adequate side wall integrity to prevent side wall deflection when being handled. For example, the side wall may be easily deflected inward, constricting the volume of the container and forcing out the contents of the cup.
- U.S. Pat. No. 6,554,154 (“Chauhan”) discloses a thermoplastic container having a first set of horizontal annular rings disposed adjacent to a top portion of a side wall of the container and a second set of annular rings disposed in a middle portion of the container. The annular rings (or “ribs”) increase side wall integrity and improve deflection characteristics over prior art designs. The thermoplastic container disclosed by Chauhan, however, may not provide sufficient thermal insulation to serve as a hot-beverage container. Additionally, the container disclosed by Chauhan does not have the desired look and feel of a paper cup, and its exterior surface is not suitable for high-quality printing.
- It would be advantageous, therefore, if there were available a disposable beverage container having sufficient thermal insulation properties to contain hot beverages, as well as an exterior surface that is suitable for the attachment of promotional items and for high-quality printing from the lip of the cup to its base.
- A beverage container according to the invention may include a polypropylene cup body covered with a paperboard wrapping. The cup body may have a bottom and a side wall extending from the bottom. The side wall may form an open end opposite the bottom. The cup body may have a plurality of annular ribs disposed adjacent to one another circumferentially around the side wall parallel to a plane defined by the bottom of the cup body.
- The paperboard wrapping may be disposed circumferentially around an exterior of the cup body, and may abut at least one of the ribs such that a thermally insulating gap is formed between the cup body and the paper wrap. The paperboard wrapping may provide for high quality printing on the entire exterior of the cup. Additionally, the paperboard wrapping may permit the use of attachments such as those a beverage vendor may use as promotional items. Examples of such promotional items include detachable coupons, tear-off labels or stickers, or playing pieces for a game.

gaps 118 may be an insulating air gaps, helping to protect the consumer's fingers from the heat or cold of a beverage that may be contained in thebeverage container 100. Additionally, insulating air gaps such as thegaps 118 may help insulate the contents of the beverage from the ambient temperature and retard the cooling of a hot beverage or the warming of a cold beverage. The insulating characteristics of thebeverage container 100 may also be adjusted by varying a thickness of thepaper wrap 115 or of theside wall 120. -
FIG. 7 is a cut-away side view exposing the interior of thebeverage container 100 in the vicinity of thetop portion 130. Thelip 135 may be formed by rounding thetop portion 130 of theside wall 120 or by any technique known to those skilled in the art. Additionally, thelip 135 may provide astop 139 against which thepaper wrap 115 may abut. -
FIG. 8 is a top view andFIG. 9 is a bottom view of thebeverage container 100. Thelip 135 is of substantially the same round shape as the bottom 140 but has a larger diameter than the bottom 140. In this way, thebeverage container 100 has a tapered shape. Theribs 125 are shown on the interior of thebeverage container 100, as are theinterior base portion 141, thetransition portion 142 and theexterior base portion 143. Thesmooth paper wrap 115 is shown on the exterior of thebeverage container 100, as are theinterior base portion 141, thetransition portion 142 and theexterior base portion 143. -
FIG. 10 is an isometric view of analternative paper exterior 215 for a beverage container in accordance with an alternative embodiment of the invention. Thepaper exterior 215 differs from thepaper wrap 115 in that thepaper exterior 215 includes apaper side wall 216 and apaper base 245. -
FIG. 11 is a cut away side view of abeverage container 200 comprising apaper exterior 215 and acup body 110. Thecup body 110 may be thecup body 110 described with regard toFIG. 2 . Thepaper exterior 215 may cover both theside walls 120 and thebottom 140 of thecup body 110. Thepaper exterior 215 may include a base 245 that is closed such that thebottom 140 of thecup body 110 is concealed. The base 245 may be adhered to thebottom 140 of thecup body 110. Alternatively, thebase 245 may be attached to thepaper side wall 216 such that thecup body 110 may be inserted into thepaper exterior 215. Theribs 125 and thepaper side wall 216 may form insulatingair gaps 118. Thepaper exterior 215 and theside wall 120 of thecup body 110 may be adhered to each other using an adhesive or other suitable method. Additionally, the bottom 140 may also be adhered to thepaper base 245 by any suitable method. -
FIG. 12 is a cutaway side view of abeverage container 200 in the vicinity of thebase 245. Theside wall 216 of thepaper exterior 215 may be folded at thelowermost edge 217 to form a receivingportion 218. Thepaper base 245 may be inserted in the receivingportion 218 and attached to aside wall 219 of the receivingportion 218 using adhesive or by any suitable method. In this way, thepaper base 245 may be interconnected with thepaper side wall 216. - Thus, there have been described an insulated beverage container with improved deflection characteristics and a method for making such a container. It will be appreciated that numerous modifications may be made to the example embodiments described herein, and that such modifications do not depart from the scope of the invention as defined by the following claims.
