Abstract: A container (15) for dispensing a fluid (16) comprising an outer flexible shell (18) having a dispensing port (19), an inlet (20) and an inner surface (21) defining a chamber (22) having a chamber volume, a collapsible receptacle (23) in the chamber configured and arranged to hold a fluid (16) and having an outer surface (24) and an inner surface (25) defining a storage volume (26), the shell and the receptacle defining an air volume (28) between the inner surface of the shell and the outer surface of the receptacle, the receptacle having an outlet (29) aligned with the shell dispensing port, a one-way check valve (30) in the shell inlet port configured to permit airflow (31) into the air volume and not into the holding volume and to block airflow out of the air volume, the shell, receptacle and valve configured and arranged such that a selective force applied to the outside of the shell decreases the chamber volume while the air volume remains substantially the same, thereby pressuring the fluid to exit the

Abstract: An improved connector (15) for selectively joining two parts (16, 32), each of the parts having inner (18, 33) and outer (19, 34) surfaces and a keyhole opening (20, 35) between the inner and outer surfaces, each of the keyhole openings having first (21, 36) and second (22, 38) spaced enlargements and a slot (23, 39) extending between the first and second enlargements, comprising a body (48) having a first portion (49) configured to pass through the first enlargements but not to pass through the second enlargements, a second portion (50) configured to not pass through the second enlargements, and a third portion (51) configured to move in the slots between the first enlargements and the second enlargements, a member (58) in engagement with the body and moveable relative to the body between a first position (61) and a second position (62) and having a first portion (59) configured to move in the slots between the first enlargements and the second enlargements, and a second portion (60) configured to extend thr
