A preform and a blow molded container formed therefrom and having plural cavities or compartments for providing enhanced properties including vacuum containers for hot and cold product, or barrier materials including gases or layered material, improved creep resistance, use of lower cost and/or recycled materials, increased wall strength and aerosol properties.

A fuel delivery system comprises a fuel conduit having a gas permeable wall. A gas conduit is in communication with the fuel conduit. Gaseous fuel and liquid fuel are communicated through fuel conduit. Gaseous fuel permeating through the gas permeable wall is captured and channeled by gas conduit. Gaseous fuel may be passed to an air intake manifold and consumed by engine combustion.

An ultrathin walled rolling bearing in which the noise level is reduced and thus the sound characteristics are improved is provided. The rolling bearing is composed of an outer member having in its inner periphery a raceway surface, an inner member having in its outer periphery a raceway surface, a plurality of rolling elements interposed between the raceway surfaces of the outer and inner members, and a cage for circumferentially equi-spacing the rolling elements. In this bearing, the ratio of ...

A flexible-walled security container has an opening provided with a fastener slidable along edges of the opening and a locking mechanism to releasably retain the slider in a position closing the container. The locking mechanism includes a body supporting a receiver with a recess in an upper surface thereof to receive the slider and a retainer closable on the received slider. Lugs at one end of the recess prevent slide removal of the slider. Gaps are formed along the upper surface between the lug...

This invention pertains to alkaline electrochemical cells, typically to metal-air cells of the button-type. Non-reactive elements of cells of the invention are thinner than corresponding non-reactive elements of prior art cells. Such elements can be made thinner because of improved structures of such elements. The anode can is made from a metal strip structure having a higher steel content. The cathode can has a modified temper, which improves relative stiffness and rigidity while retaining suff...

An object of the present invention is to provide a structure employable for a thin-walled hinge(s) which assures that there does not arise a malfunction that each thin-walled hinge is undesirably bent and that an operation for connecting two components to each other and disengaged from each other can be performed at an improved efficiency. A pair of thin-walled hinges for firmly connecting a double engagement member to a housing main body are designed in the form of a pair of rectangular band-sh...

A one-piece, lightweight, molded plastic hat that comprises, in combination, a thin, molded plastic sheet forming a hat wall dome having an inner side, the sheet at the dome everywhere having thickness less than 3/16 inch; the sheet at the dome forming a corrugation having a local portion defining a U-shaped cross section; and a local plastic reinforcement sub-sheet formed to have U-shaped cross section matching that of the dome local portion, the sub-sheet fitting and adhesively bonded to the d...

A dual walled insulating paperboard container is disclosed. The container preferably includes an inner cup and an outer cup each having tapered sidewalls. The sidewalls, however, have different angles of taper to provide an insulating cavity therebetween. Additionally, the bottom of the inner cup is spaced from the bottom of the outer cup to create an insulating barrier along the bottom of the container. The outer cup also includes a stepped region along its top that cooperates with a curled top...

Multi-walled panel-like structure having an upper and lower wall integrally bonded to support ribs located therein between with closed cell foam being placed in the interstitial spaces between the walls and ribs. Improved strength is provided by this apparatus and method of construction. The invention is particularly suited for retrofitting single wall tanks and tank bottoms to be double walled tanks and tank bottoms.
