Appl. No.:

09/833521

Inventors:

James Curtis - Clyde NC, US

International Classification:

B32B001/02

US Classification:

428/034200

Abstract:

The present invention relates to an improved laminate for containers of liquid, such as juice, the laminate comprising: a paperboard substrate; an outer layer of a member selected from the group consisting of heat-sealable low density polyethylene polymers and Plexar; and an inner barrier layer of a polymeric nanocomposite blend comprising at least one resin and a layered silicate dispersed in said resin. The layered silicate preferably has a layer thickness of about 7 to 12 A and an interlayer thickness of about 30 A or greater.

International Classification:

F02M 5502

US Classification:

123470

Abstract:

An assembly including an engine component, such as a fuel injector, seated against a seating surface of a cylinder head is provided with a positive seal contact an uppermost point of contact between an injector sleeve and a seating surface of the cylinder head. The positive seal contact prevents coolant from the water jacket from travelling below the uppermost point of contact, thereby avoiding cavitation damage which might otherwise occur by the entrapment of liquid between the cylinder head seating surface and the injector sleeve. In an embodiment, a raised annular ridge is formed in the seating surface of the cylinder head at the location of the uppermost point of contact. This ridge becomes embedded in the injector sleeve. Also, in an embodiment, the cylinder head includes a circular recess upwardly from the uppermost point of contact. Although coolant from the water jacket can enter the recess, the recess radially separates the cylinder head from the injector sleeve by an amount that will not be closed under deflection due to cyclic loading on the injector.

Abstract:

A laminate providing an effective barrier to migration of essential oils and flavorings and for retention of vitamin C, essential oils and flavor in a juice and cartons made therefrom, wherein the laminate comprises, from the outer surface to the inner surface contacting the juice: an outer polyethylene layer for heat sealing and graphics, a bleached sulfate paperboard substrate, a nylon barrier layer constituting a barrier for oxygen, a first tie layer of modified polyethylene acting as an adherent, another polyethylene layer acting as a heat seal layer and bonded to the nylon barrier layer by the first tie layer, a second tie layer acting as an adherent, and an inner skin layer, which contacts the contents of the carton, which is bonded to the polyethylene layer by the second tie layer, and which may be ethylene vinyl alcohol copolymer (EVOH), polyethylene terephthalate or nylon.
