A combination cap and work support system includes a lower section configured to connect to a container and an upper section configured to provide a desired support to an object. The combination cap and work support system may be utilized alone or in multiples to support an object above a work surface during a project. Configurations of the upper section generally include multiple apices separated by areas having a reduced height, and configured to support an object directly on the apices, or between the apices, to provide a desired combination of support and stability. The combination cap and work support system may be included as part of a kit in conjunction with a compatible container, such as a can of sprayable surface coating.

The disclosure includes a cap having a first portion made of a plastic material and forming a bottom for covering a container neck and a protective side wall for surrounding the container neck, and a second portion made of a flexible material that is compatible with the plastic material of the first portion and separate from the plastic material of the first portion, the second portion being annular and consisting of a flexible seal, which projects from the bottom toward the interior of the side wall and which is welded to the first portion. Thus, the manufacture of the stopper by molding includes injecting a flexible material to produce the flexible annular seal and then the movable portions of the mold are placed such that the flexible material is in a groove that is set back from the planar surface of the mold.

A vehicle door handle apparatus is disclosed that generally includes a structural core and an outer layer. The structural core has an outer surface, a base portion, and a handle portion that extends from the base portion. The outer layer extends about and covers the outer surface of at least the handle portion of the structural core. The structural core is made of a first material that contains an engineering thermoplastic and glass fibers for reinforcement. The outer layer is made of a second material that contains the engineering thermoplastic and a milled material to give the outer layer a metallic surface finish. Non-limiting examples of the engineering thermoplastic are polyoxymethylene and polybutylene terephthalate. A method is also disclosed for producing an injection molded component having a metallic surface finish such as the disclosed vehicle door handle apparatus.

An oral care implement having a multi-component handle. The oral care implement may include a head and a handle. The handle may include a transparent component and an opaque component. The transparent component may have a front surface, a rear surface opposite the front surface, a first lateral surface, and a second lateral surface opposite the first lateral surface. The opaque component may at least partially cover the front and rear surfaces of the transparent component while leaving the first and second lateral surfaces of the transparent component exposed. Thus, the transparent component may form a window through the lateral surfaces of the handle.

The invention is a valvular closure element (5), in particular for dispensing a liquid from a container, the valvular closure element (5) comprising a support element (10) having an annular shape and a valve insert (12) having a side wall and a cover portion made of a resilient material and abutting to an internal surface of the support element (10) by its side wall. The cover portion (17) is formed with slits (14) defining valve flaps (15), wherein each valve flap (15) has an adjoining periphery connected to the side wall. In the valvular closure element (5) the side wall has a cylindrical shape, and the slits (14) are formed radially, and a projection (18) is formed on the external periphery of the support element (10) for each valve flap (15) at the middle of the adjoining periphery corresponding to the respective valve flap (15). The invention is, furthermore, a closure cap comprising the valvular closure element (5), and a method and an apparatus for manufacturing the valvular closure element (5). The invention also relates to another valvular closure element.

A method of manufacturing a chrome plated component can include performing a two-shot (2K) molding process to form a component comprising first and second \members. A non-plateable resin can be molded to form the first member defining a front surface that defines a recess. A plateable resin can be molded to form the second member defining a back surface that defines the protrusion. The component can then be removed from its mold, where (i) an exposed surface of the second member defines a front surface of the component and (ii) the recess receives the protrusion such that the front surface of the first member is substantially flush with the back surface of the second member. An exposed surface of the second member can then be chrome plated to obtain the chrome plated component.

The cover of a plastic tank suitable for containing water is attached to the tank base by means of alternative joints, including elastically engageable features and lock features to prevent unwanted release. The base of a plastic water tank is comprised of a substrate and a liner and is formed by means which include injection molding into a mold where the core part of the mold is surrounded in part or full by the film which forms the liner.

Methods and systems for co-extruding multiple polymeric material flow streams into a mold having a plurality of cavities to produce a plurality of multi-layer polymeric articles each having a consistent coverage of an interior core layer are disclosed herein. In an example method, a flow rate of a first skin material into a cavity is individually controlled for each cavity before initiation of co-injection of a second core material into the cavity, which may address inconsistent interior core layer coverage for articles from different cavities.

A method for making an oscillating weight for an automatic winding mechanism of a self-winding watch including a central part made from a first composite material and a heavy sector made from a second composite material charged with heavy metal particles, the method including: forming the central part with a lateral rib and a rebate by injecting the first composite material into a mold; overmolding the heavy sector onto the central part by injecting the second composite material into a mold containing the central part, so that the second composite material fills the rebate and a gap underneath the lateral rib, so that the lateral rib is embedded in the second composite material and the central part and the heavy sector are interlocked.
