Systems and methods for limiting transmission of vibrations and forces causing vibrations from one element to another are provided. A vibration isolator may include a compressible inner member and an outer member compressible with the inner member. The outer member may be positioned at least partially around the inner member to provide lateral support to the inner member. The outer member may maintain a consistent diameter and compression force when in a compressed state. The outer member may include a tube with a zero or near-zero Poisson's ratio.

A dispensing pump (10) for liquids, viscous materials, foams, gels, etc. includes a resilient cup spring (18) so that the entire pump can be more easily recycled. The dispensing pump (10) includes a base portion (12), an inlet valve (14), a piston valve (16), a cup spring (18), a spring guide structure (20) and a pump actuator (22). When actuated, the cup spring (18) is elastically deformed over opposing spring ribs (39), and then upon release, the cup (18) elastically returns to its normal at rest shape, returning the guide (20) and pump actuator (22) to their normal at rest positions. The cup spring (18) includes structures which interact with the piston valve (16) to open the outlet valve.

Embodiments provide a support structure for an article of footwear, which may include upper and lower support elements, upper and lower members, a compression element disposed between the upper and lower members, and a torsion element. A vertical force applied to the upper support element compresses the compression element, rotationally displaces in a first direction the upper member relative to the lower member, rotationally displaces in the first direction a second portion of the torsion element relative to a first portion of the torsion element, deflects a torsion loading portion of the torsion element, and moves the upper member vertically toward the lower member. Upon release of the force, the torsion loading portion rotationally displaces in a second direction opposite to the first direction the second portion of the torsion element relative to the first portion. Embodiments of methods of manufacturing a support structure are also disclosed.

A dispenser for dispensing flowable, for example liquid or paste-like, compounds, includes a storage reservoir for receiving the compound, and a preferably modular dispenser pump having an inlet channel and an outlet channel and a pump chamber delimited on the inlet and the outlet side by valves, and also having a head piece, the head piece having a dispensing opening, and a restoring device formed by a spring is further provided between the head piece and the storage reservoir. The restoring device is formed by a plastic spring having a lower spring washer and an upper spring washer, which are arranged substantially coaxially with one another, a respective plane spanned by each spring washer extending substantially perpendicular to a longitudinal axis of the plastic spring, and furthermore the spring washers being compressibly connected to one another by sprung struts extending over more than 90 degrees in the circumferential direction.

A damper is disposed in a holding hole that passes through, in a passing-through direction, a supported member that is supported by a supporting member. The dumper includes a tubular body defining therein a through hole extending in the passing-through direction. The tubular body is elastically deformable between a first form and a second form. The tubular body in the first form has an outer shape that is smaller than the holding hole. The tubular body in the second form has an outer shape that is equal to or greater than the holding hole.

A dispensing tap for liquids includes a body connected to the neck of a container, a dispensing head with an outlet or mouth, and a throat connecting the body to the dispensing head. A shut off valve is configured for sealing engagement with the mouth of the dispensing head, and a piston is axially guided within the dispensing head. The piston includes a peripheral seal slidably engaged with an interior surface of the dispensing head, and a valve stem coupled to the shut off valve. The piston is selectively actuable between a normally closed position an open position. A vent is in communication with an interior of the body and the vent is opened and closed with movement of the piston and shut off valve.

An all plastic compression spring assembly includes a slotted tubular spring element formed from a tensile polymer material and upper and lower loading cones received at opposing upper and lower ends of the slotted tubular spring element. The upper loading cone may be axially compressible towards the lower loading cone within the slotted tubular spring element whereby the slotted tubular spring element radially expands in tension to create an opposing radial contraction force, and in turn, an axial extension spring force. When released, the spring element elastically returns to its normal at rest shape, returning the cones to their normal at rest positions. In some dispenser configurations, the lower loading cone may be stationary or fixed within the dispensing head and the upper loading cone may be downwardly compressible toward the lower loading cone by movement of a nozzle head.
