Benefits of technology

[0011] In accordance with this invention, the product cup is made of modular dimensions, and the interior of the outer container is made of standardized dimensions for reception of the modular cup. After the modular cup is received in the outer container, juxtaposed flanges on the cup and the container are fused together, preferably by spin welding. Thus, the modular cup having a standard size can be supplied from different suppliers, thereby promoting wide commercial acceptance.

Problems solved by technology

More specifically, each self-heating arrangement is designed with proprietary dimensions so that a product cup supplied by one supplier with one set of dimensions cannot be interchangeably used with a product cup supplied by a different supplier with a different set of dimensions.
Commercial acceptance of custom-made, self-heating arrangements has been limited.

Embodiment Construction

[0023] As best shown in FIGS. 1-2, an arrangement in accordance with this invention includes an outer container 10 having a side wall 12 bounding an interior, an inner product cup 14 fixedly mounted within the interior of the container 10, a breakable membrane 16 fixedly mounted within the interior of the container 10 and subdividing the interior into a pair of compartments 18, 20, a pair of reactants 22, 24 respectively contained in the compartments 18, 20 and kept apart by the membrane 16 prior to use, and a breaking member 26 mounted within the container 10, preferably above the membrane 16, and operative for breaking the membrane 16, as described below, to allow the reactants 22, 24 to mix and form a chemical reaction that changes the temperature of a product contained in the cup 14. A seal 28 seals the product within the cup 14. An apertured sip lid 30 is optionally mounted over the seal 28 and over the container 10.

[0024] The container 10 is symmetrical about an upright axis ...

Abstract

A modular product cup is mounted in an outer container of standardized dimensions in an arrangement for changing the temperature of the product in the cup. The cup can come from different product suppliers, each able to use its product cup in the arrangement to promote wide commercial acceptance.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a continuation-in-part of pending U.S. patent application Ser. No. 11 / 175,818, filed Jul. 6, 2005.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention generally relates to an arrangement that adds or removes heat from a product, such as a food, beverage, medicine, or like product and, more particularly, to a system for and a method of making the arrangement that promotes wide commercial acceptance. [0004] 2. Description of the Related Art [0005] Self-heating or self-cooling arrangements are known in which a product, typically a beverage, is heated or cooled by employing two chemical reactants which are stable when separated, but which produce an exothermic or an endothermic reaction when mixed. U.S. Pat. No. 4,793,323 shows one example of a single-use, self-heating arrangement container for liquids or solids, in which a breakable membrane keeps the reactants apart, and a breakable...
