It is an object of the present invention to provide improved methods and compositions for manufacture and use of lateral flow test devices. In particular, the present invention provides a molding method which provides one or more features in the housing base configured to retain the test strip within the base. These features are provided as undercuts in the housing base. The test strip is configured as a bibulous lateral flow material disposed on a substantially non-compressible base layer, and the base layer is positioned within the undercut in order to retain the test strip in the housing base. Optionally, one or more features in the housing base which create the undercut are configured to engage the bibulous lateral flow material by compression and/or friction, thereby increasing the ability of the base to maintaining the test strip in its proper position within the device.

An undercut processing mechanism includes: a core pin for forming an inner circumferential surface of a tubular projection; a slide core for forming an outer circumferential surface of the tubular projection; a sliding piece for causing the core pin to advance/retract in an axial direction of the tubular projection; a retaining piece for causing the sliding piece to advance/retract; a holder for accommodating the retaining piece such that the retaining piece can advance/retract; and a movement amount restrictor for restricting a movement amount of the core pin. The retaining piece is operable to advance/retract in a state where a stationary die and a movable die are closed. When the core pin retracts in conjunction with retraction of the retaining piece and a movement amount of the core pin reaches a restricted distance, the core pin and the slide core retract together, thereby allowing an undercut portion to be demolded.

A roller is capable of smoothly rotating without any burr on a rolling surface. A dish washer including the roller includes: a case; a basket configured to accommodate dishes; a rail configured to guide the basket to be put into or taken out of the case; and a basket roller coupled with the basket and configured to move along the rail, the basket roller comprising a rolling portion configured to roll in contact with the rail, a first flare portion extending in a first direction from the rolling portion, and a second flare portion extending in a second direction from the rolling portion, the second direction being opposite to the first direction, wherein a diameter of the first flare portion is greater than a diameter of the second flare portion.

Provided is a plunger including: a plunger body; a first surface configured to come into contact with an inner peripheral surface of the cylindrical member; a second surface disposed on a base end side relative to the first surface, the second surface having an outer diameter that is smaller than that of the first surface; an outer stepped surface disposed between the first surface and the second surface; a first housing disposed in an area at least partly corresponding to the second surface in the recess, the first housing being provided for housing a tip part of the pin; a second housing disposed on the base end side relative to the first housing, the second housing having an inner diameter that is smaller than a largest inner diameter of the first housing; and an inner stepped surface disposed between the first housing and the second housing.

A heat stake for a plastic part includes a body having a proximal end, a flared section and a distal end. The proximal end has a first cross-sectional area A.sub.1 and the flared section has a second cross-sectional area A.sub.2 where A.sub.1<A.sub.2. The distal end has a dual taper. That plastic part incorporating the heat stake is also disclosed.

A method of forming a resilient seal about a work piece is presented. The method includes the steps of providing a work piece defining a rib circumferentially protruding from an outer surface about a longitudinal axis of the work piece and providing a mold. The mold defines a first cavity configured to receive the work piece, a second cavity circumferentially extending about the longitudinal axis of the work piece and in communication with the first cavity, and a port in communication with the second cavity. The method further includes the steps of inserting the work piece within the first cavity such the rib is circumferentially in intimate contact with an inner surface of the first cavity, introducing a curable resilient material into the port, thereby filling the second cavity with the resilient material, curing the resilient material, and then removing the work piece from the mold.

A tamper evident cap assembly includes an outer cap having an outer cap end wall and an outer cap skirt, and an inner cap having an inner cap end wall and an inner cap skirt. The inner cap skirt has a thread on an inner surface for selectively fastening the cap assembly on a portion of a container. The thread has separations therein. The first and second vertical ratchet teeth of the outer cap and the inner cap, respectively, abut when the outer cap is turned in an application direction to rotate the inner cap and the outer cap together to fasten the inner cap onto the container. When a downward force is applied on the outer cap, the second end teeth on the inner cap engage with the first end teeth on the outer cap applying torque on the outer cap in the removal direction turning the inner cap to release the cap assembly from the container and rupture the tamper evident band.

The invention relates to a steering wheel (1), especially a leather steering wheel, comprising a steering wheel skeleton (10), a foam padding (11) surrounding the steering wheel skeleton (10) at least partially and a wrapping (12) which encompasses the foam padding (11) at least in portions, wherein adjacent longitudinal edges (13) of the wrapping (12) are covered by a profile bead (20), in particular a decorative bead (24), the profile bead (20) including at least one anchoring element (21) which is fixed directly in the foam padding (11) for fastening the wrapping (12). Moreover the invention relates to a method of manufacturing such steering wheel.

A damper is formed by a housing member wherein an outer cylinder portion and an inner cylinder portion that are cylindrically formed are concentrically disposed, and respective lower ends are connected to each other at a bottom portion, and at an upper end of the outer cylinder portion, an open end portion is formed, and a groove portion is formed on an inner periphery; and a lid member provided with a rotor inserted from the open end portion, and housed in the housing member, and formed with a projection portion engaging the groove portion. A thin wall portion which is thinner than the outer cylinder portion is formed in a vicinity of a groove portion side in the outer cylinder portion.
