Abstract
A disposable paper cup for serving cold food products and beverages is converted into a hot cup by the addition of an insulating sleeve assembled on the cold cup by the user. One part of a cohesive compound carried by the cold cup cooperates in registry with another part of the cohesive compound carried by the insulating sleeve to instantaneously and aggressively adhere the sleeve in assembly with the cold cup when the sleeve is mounted on the cold cup by the user.
Claims20
An article of manufacture comprising a disposable cold cup formed from sheet material for containing cold liquid and having a frustoconical sidewall, a radially disposed annular rim at the upper end of said sidewall defining an opening at said upper end, and a radially disposed bottom wall, and means for converting said disposable cold cup into a disposable insulated cup for containing hot liquid and including a frustoconical insulating sleeve made from sheet material for coaxially receiving said disposable cold cup in an assembled condition therein, and a cohesive material having two parts including a first part disposed on a portion of the outer surface of said sidewall and a second part disposed on a portion of the inner surface of said sleeve for registry with said first part in said assembled condition, said first and second parts instantaneously cooperating in adhering engagement with each other when brought into contact with each other in said assembled condition to permanently retain said sleeve in insulating assembly with said sidewall, whereby said insulating sleeve may be permanently assembled with said cold cup by a user at the time of use.
An article of manufacture comprising a disposable cold cup formed from sheet material for containing cold liquid and having a frustoconical sidewall, a radially disposed annular rim at the upper end of said sidewall defining an opening at said upper end and a radially disposed bottom wall, and means for converting said disposable cold cup into a disposable insulated hot cup at the time of use for containing a hot liquid and including a frustoconical insulating sleeve made from sheet material for coaxially receiving said disposable cold cup in assembled condition therein, and retaining means for instantaneously securing said insulating sleeve in permanent assembly with said disposable cold cup when said disposable cold cup and said insulating sleeve are brought together in said assembled condition and including first means carried by said disposable cold cup and second means carried by said insulating sleeve for instantaneously cooperating in permanent holding engagement with said first means in said assembled condition whereby said insulating sleeve may be assembled with said disposable cold cup by the user of said disposable insulated hot cup and at the time of use.
A method for converting a disposable cold cup into a disposable insulated cup at the time of use comprising the steps of providing a cohesive material including two parts which instantaneously adhere to each other upon contact with each other, applying one part of the cohesive material to the outer surface of the cold cup, forming an insulating sleeve for receiving and engaging the cold cup in an assembled condition therein, applying a quantity of the other part of the cohesive material to the inner surface of said sleeve for registry with the one part in the assembled condition, and moving the cold cup into assembled condition the sleeve at the time of use to bring the one part into face-to-face engagement with the other part causing the one part and the other part to instantaneously cooperate in adhering engagement with each other to permanently secure the insulating sleeve in insulating assembly with the cold cup.
