Abstract: A beverage container for original content is comes with at least one additional piece on the inside of the container. Each additional piece provides a selectively breakable or rupturable packet that contains an amount of additional content or an additional ingredient such as flavoring or caffeine. When the container is slightly squeezed or “crunched” the packet is ruptured and releases the additional content into the original content.

Abstract: A plurality of dispensers of thin polymeric envelopes are distributed throughout a public exercise facility whereby the users can extract the envelopes to cover the contact areas of the exercise device that they will be using. When finished, the shielding envelopes are removed and discarded into a collection receptacle to be thereafter recycled. Preferably the envelopes are formed of a thermoplastic polymer structure and are therefore sterilized directly in the course of recycling. Each envelope may include a transparent portion that can be aligned over various exercise data displays and may be provided with a releasable attachment by which it is retained during its use.
