    Abstract: A vented liquid containment device has a cup member located within the structure of a threaded cap so that a filter material can be placed within the cup member to prevent liquids from being splashed in an upward direction into contact with a vent that is formed within an inside portion of the cap. When used in conjunction with a marine vessel, rough water can cause oil within an oil reservoir to splash upwardly and come into contact with the vent opening which is intended to allow air and other gases to pass back and forth between the cavity of the reservoir and the atmosphere. The presence of the filter material prevents the liquids from being splashed into direct contact with the vent openings which could otherwise allow oil to spill outwardly onto surfaces of the reservoir and nearby components.

  • Patent number: 6730004
    Abstract: A blow-moldable container, having a centrally located, generally tubular handle spanning a central recess has improved balance and ergonomics over existing blow-molded containers. Such a balanced container has great utility as a handheld freeweight, or as a container for pourable substances. An integrally molded base allows our container to be stood upright on end like a regular bottle. Products may be marketed in such containers under the premise that the consumer automatically acquires a freeweight by purchasing the product. The inclusion of fitably engageable contours on its top and bottom surfaces makes such a container stackable with others of its kind, for ease of packaging, shipping, and storage. A graduated set of handheld fillable freeweights may thus be compactly stored without a special rack. Since blow-molding offers great economy of production for sufficiently large numbers of containers, the average person will now be able to afford an entire graduated set of freeweights.

  • Patent number: 6523711
    Abstract: A sports bottle cap having a pressure differential valve is provided which allows water to flow out through the bottle cap only when the bottle is inverted and squeezed or alternatively a straw may be threaded through the pressure differential valve, thereby deactivating it, and attached to the bottle cap allowing the user to draw liquid from the bottle through the straw. In operation the bottle cap of the present invention allows the user to dispense fluid from within the bottle in two different ways. The first manner of use allows liquid to be dispensed only when the bottle containing the liquid is inverted and squeezed. Squeezing causes the pressure to increase on the inside of the bottle thereby causing the pressure differential valve to open and liquid to exit; however, when the bottle is not squeezed the pressure differential valve remains in the closed position sealing bottle.

  • Patent number: 6312364
    Abstract: A blow-moldable container, having a centrally located, generally tubular handle spanning a central recess has improved balance and ergonomics over existing blow-molded containers. Such a balanced container has great utility as a handheld freeweight, or as a container for pourable substances. An integrally molded base allows our container to be stood upright on end like a regular bottle. Products may be marketed in such containers under the premise that the consumer automatically acquires a freeweight by purchasing the product. The inclusion of fitably engageable contours on its top and bottom surfaces makes such a container stackable with others of its kind, for ease of packaging, shipping, and storage. A graduated set of handheld fillable freeweights may thus be compactly stored without a special rack. Since blow-molding offers great economy of production for sufficiently large numbers of containers, the average person will now be able to afford an entire graduated set of freeweights.

  • Patent number: 6274209
    Abstract: A venting cap (1) has a cavity (7), at least one first passage (4) for fluids connecting the cavity (7) with the inside of the container, at least one second passage (5.1, 5.2, 5) for fluids connecting the cavity (7) with the outside of the container, and a liquid-absorbing mass (8) arranged within the cavity (7). The liquid-absorbing mass (8) acts, after absorption of liquid, as a selective filter prohibiting the passage of liquid, but permits the passage of gas. This ensures the foolproof selective permeation of gas but not of liquid. Venting properties remain unaltered even at extreme conditions of transportation and storage.
