Collapsible containers and a method of their manufacture are disclosed herein. The collapsible containers have one or more collapsible wall sections and a stiff upper and lower tier. The wall sections have living hinges and three or more tiers between the hinges. A thermoplastic elastomer layer may join separately made portions of the container together. The containers may be made by molding and overmolding. The containers include inter alia bulk liquid containers, jugs, tubs, baskets, bottles, and food containers. The method of manufacturing includes placing a container component and a matching container body comprising a stiff first tier, a stiff second tier, and a collapsible wall section in a mold; assembling the container body with the container component to close one end of the container body; and overmolding a thermoplastic layer around the container body and the container component.

A wafer container with a latch mechanism that provides sealing for large wafer containers, such as for 450 mm wafers, accomplishes secure door closing and latching with reduced torque requirements for rotating the central rotatable cam plate. In various embodiments, a camming slot formed in the rotatable cammed plate is arcuate and defined by opposing cam surfaces which are selectively engaged by a cam follower, such as a roller, attached to a proximal end of a latch arm. The roller can include unitary axle portions that snap into the proximal end of the latch arm and is supported at both axial ends of the roller. The proximal end of the latch arm can include parallel extensions separated by a gap, and have guide in surfaces to deflect the extensions as the axle portions of the roller are forced into position thereby seating the roller at both axial ends.

A tiltable lid assembly includes a base that is secured to a cup that holds a liquid substance. The base has an opening that is aligned with an opening on the cup. A cap assembly is secured to the base and includes a first seal for sealing the opening of the base and a second seal for sealing an air vent on the base. The cap assembly is tiltable along an axis, wherein in a first position, the cap assembly is in a level, non-inclined position and the first and second seals seal the opening and the air vent, respectively. In a second position, the cap assembly is inclined and the first and second seals are displaced from the opening and air vent. Releasable locking means secures the cap assembly in the first and second position.

A respiratory assistance apparatus includes a flow generator and a humidifier. The humidifier includes a humidification chamber. The humidification chamber comprises a water tub that is configured to receive a volume of water. A lid is hingedly coupled to the water tub for enclosing a volume contained within the water tub.

A container for storing a food product includes a receptacle and a plunger slidably movable along an inner wall of the receptacle. The plunger includes a support surface for the food product and a seal configured to form a seal between the support surface and the inner wall. A rounded lid with an apex is configured to be sealingly coupled to the receptacle. The lid includes a vent located at the apex.

A closure for a lid that has at least one opening may include an activator pivotally coupled to the lid, a cover pivotally coupled to the lid, and a connecting member pivotally coupled to the activator and the cover. The activator, the cover and the connecting member may form an over center latching mechanism. In addition, the activator may be pivotally connected to the lid about a first axis of rotation, the cover may be pivotally connected to the lid about a second axis of rotation, the connecting member may pivotally connected to the activator about a third axis of rotation, and the connecting member may be pivotally connected to the cover about a fourth axis of rotation. The distance between the first and second axes of rotation may be constant, and the distance between the third and fourth axes of rotation may change as the cover is moved.
