A method of forming a handle for an oral care implement. The method may include first forming a core structure out of a first hard plastic. Next, an elongated handle body may be formed out of a second hard plastic, whereby during formation the elongated handle body is made to partially surround the core structure, while leaving opposing surfaces of the core structure exposed. Finally, a grip cover may be formed out of a resilient material and positioned over at least a portion of the elongated handle body. The oral care implement handle formed by the method may include a handle having an elongated handle body and a core structure. The elongated handle body may have openings in opposing surfaces. The core structure may be partially surrounded by the elongated handle body while protruding from the openings.

Method for making blow molded articles having a predetermined feature incorporated into the wall provided by variations in the thickness of the wall of the article corresponding to a predetermined pattern etched into the preform from which the article was formed.

A semicrystalline copolyester resin composition formed by twin screw extrusion of various ingredients includes copolyester resins, antiblock, slip and antifog additives. This semicrystalline copolyester resin can be extruded on to PET film or coextruded with PET resin to form clear PET films with antifog properties. These films with antifog properties are produced in a single step without the use of solvent and does not involve any secondary step for coating a separate antifog layer. This minimizes the cost and time required by a converter to make such clear antifog films. These films containing the heat seal copolyester resin can be heat sealed to clear APET trays. Contents within the trays, such as food, can be seen without fogging on the inside of the film that is used to seal the tray. The seals are strong and the peels are smooth giving a very good packaging performance.

A method for potting electrical components into complex finishing forms is presented. A releasing agent is added into a mold cavity. Next, an initial layer of potting compound is added into the mold cavity. A label layer is added into the initial layer of the potting compound. A set of electronic components is added over the label layer. An interstitial layer of potting compound is added over the set of electronic components. A reinforcement layer is added along the interstitial layer. A finishing layer of the potting compound is added over the reinforcement layer forming an uncured potted electronic product. The uncured potted electronic product is cured within the mold cavity in order to produce a cured potted electronic product. The cured potted electronic product is released from the negative mold using a releasing device.

Methods for producing a dispenser for dispensable products are disclosed. The method includes attaching a label to the front plate of the dispenser by an in-mold process. The label has a label height (H2) that is less than the front plate height (H1) and label width (W2) that is less than the front plate width (W1) such that a border is formed around at least a portion of the label in the front plate. The front plate can be formed from a transparent material while the label is formed from an opaque material.

A method of manufacturing a molded solid surface includes mixing ferrous particles into a resinous material, injecting the resinous material including the ferrous particles into a mold, the mold including an upper mold half and a lower mold half, creating a predetermined pattern in the resinous material by applying a force to the ferrous particles in the resinous material toward a surface of the upper mold half or the lower mold half using one or more magnets, and curing the resinous material in the mold into the molded solid surface.
