What is presented is heating, ventilation, and air conditioning (HVAC) ductwork. The HVAC ductwork comprises a strip of material, which is divided into a plurality of circumferential segments by a plurality of living hinges. The living hinges allow the HVAC ductwork to unfold for transportation and storage purposes. The strip of material has both a first locking mechanism and a second locking mechanism that are adapted to interlock with each other at an interlocking site, to create the assembled HVAC ductwork.

Foldable HVAC conduit and duct collar

A dispenser () has a barrel (), a piston () upwardly movable within the barrel from a first position to a second position, and a body () of personal care composition at least partially within the barrel between the piston and the barrel top end (). An actuator is coupled to the piston to shift the piston upward (toward the top end). The actuator comprises a screw member having a threaded first portion () engaged to the piston for relative rotation about a first axis (). The screw has a second portion (). A cap () has a first condition mounted at the barrel top end. The cap has a socket () in an outer surface. The cap is removable from the first condition and installable into a second condition. In the cap second condition, the socket receives the screw member second portion to emit a user-induced rotation of the cap about the first axis to, in turn, rotate the first portion.

Applicators and assembly, filling, and dispensing methods

A method and apparatus for applying extrudable product to an application surface while avoiding breakdown of the product into its constituent parts or avoiding undesirable product weeping.

Dispenser

A device and a method for transferring inserts into a mold which has at least one insert receiving cavity. Included in the device are an insert positioner and an insert actuator. The insert positioner includes a transfer plate, which has a mold face with at least one insert transfer channel aperture which opens into an insert transfer cavity. Included in the insert actuator are an actuator plate, and a plate actuator. The actuator plate has at least one actuator pin extending therefrom. The actuator plate and the transfer plate are connected to so that each of the actuator pins is substantially axially aligned with the central axis of an insert transfer channel. For moving the inserts into the mold the plate actuator is adapted to move the acutator plate toward the transfer plate and thereby convey each actuator pin at least partially through each corresponding insert transfer channel. The device is adapted for operation by hand.
