INSIDE OUT METHOD OF MANUFACTURING A CONTAINER WITH A LEAK RESISTANT SEAL
20200207520 · 2020-07-02 · ·

Embodiments include a method of manufacturing a container with a leak resistant seal. The method includes forming an elastomer or a plastic or any combination thereof into a container inside out by forming an outside portion of the container on an internal surface of the container before inverting the container and forming an inside portion of the container on an external surface of the container before inverting the container. In embodiments, the method includes forming or coupling a leak resistant seal on the external surface of the container before inverting the container. The leak resistant seal provides access to the inside portion of the container when the leak resistant seal is open after inverting the container and holds at least liquid internal to the container when applying an external force to the container without use of an external structure to keep the leak resistant seal closed after inverting the container.

Photoelectric sensor

A photoelectric sensor including at least any one of a light projecting unit for emitting light and a light receiving unit for detecting light includes a substrate on which at least any one of the light projecting unit and the light receiving unit is mounted, a cover which has a protecting portion facing the substrate and for protecting the substrate and a side wall extending from a periphery of the protecting portion, and a sealing member which seals at least any one of the light projecting unit and the light receiving unit that is mounted on the substrate, in which the cover has a protruding portion on a surface which is positioned outside a side surface of the substrate and intersects an extending direction of the side wall, and the protruding portion is in contact with the sealing member.

HEATER ASSEMBLY WITH CAVITY

A heater assembly for an aerosol-generating device is provided, the heater assembly including a bushing defining an aperture at a first end of the bushing and a cavity at a second end of the bushing; a potting compound disposed within the cavity; and an elongate electrical heater extending from the first end of the bushing, where a portion of the elongate electrical heater extends through the aperture and into the cavity. An aerosol-generating device, an aerosol-generating system, and a method of assembling a heater assembly for an aerosol-generating device are also provided.

Method for forming seals on seal carriers

A method for forming seals on seal carriers, in particular vehicle doors or vehicle door frames, extrudes a sealing material strand which is to be processed to form a multiplicity of seals and has a cavity, coils or folds up the sealing material strand, forming a transportable unit that is transported to a processing site and the sealing material strand is fed continuously to a processing device by being drawn out of the transportable unit. During the processing, a section of the sealing material strand that is to be applied to the relevant seal carrier and forms the seal is in each case severed from the sealing material strand. In each case during or after the processing of the sealing material strand to form a seal, that section of the sealing material strand which forms the seal is reinforced in places at least at one predetermined longitudinal position of the section by introducing material into the cavity.

Gasket and method of manufacturing the same

The present invention improves the handling properties of a rubber-only gasket and the affixability thereof to an attachment position. To this end, the provided gasket is: obtained by combining a gasket body of the rubber-only type, and a carrier sheet that comprises a resin film and holds the gasket body in an un-adhered state; and characterized in that the gasket body is provided with an adhesive section or bonding section for adhering or bonding the gasket body to an attachment position when attaching the gasket body to the attachment position. The adhesive section or bonding section is prepared by providing the lateral surface of the gasket body with a projecting section, and coating the surface of the projecting section with an adhesive or bonding agent. The gasket body is to be used as a gasket for a fuel cell to be incorporated into a fuel cell stack.

ENCAPSULATION METHOD

A process is for manufacturing a complex motor vehicle glazing including a glass pane, an elastomer seal and a metal insert overmolded by the elastomer seal. The process includes inserting an edge of a glass pane and a metal insert into an encapsulation mold forming a leaktight cavity around the edge of the glass pane, filling the leaktight cavity containing the edge of the glass pane and the metal insert, by injecting an encapsulation composition including a polypropylene (PP)/thermoplastic elastomer (TPE) compound in the molten state, cooling the encapsulation composition to form an elastomer seal in which the metal insert is integrated, and releasing the elastomer seal from the mold. The PP/TPE compound includes from 30% to 80% by weight of polypropylene (PP) and the metal insert is covered over its entire surface liable to come into contact with the encapsulation composition, with a polypropylene coating.
