  • Patent number: 8857639
    Abstract: A device that assists with equalizing air pressure within a bottle with the atmospheric air pressure as liquid is being poured from the bottle and includes one or more relatively short air tubes. The air tubes are situated with an upper inlet rim of the air tubes located flush with or relatively near the bottle rim. Whether an insert or integrated into the manufacture of a container, the one or more air tubes that extend partially into the container allow air to pass into the container as the liquid exits the container. The pressure equalizer not only minimizes or prevents the common glugging effect, but it allows liquid from a bottle to be poured smoothly at any angle and orientation. A cap incorporating a detachable pressure equalizer is also described.

  • Patent number: 5688544
    Abstract: A container for packaging a particulate product under pressure or vacuum conditions with an easy opening closure structure which allows venting prior to uncovering of the product opening. In one form, an easy peel flexible lid covers a shelf area and a product opening in the top of the can. Peeling back the lid first uncovers the vent opening, permitting the flow of gases but preventing the flow of particulate product, and then uncovers the product opening. Alternatively, the closure structure may be formed by multiple layers of a flexible material, the lower layer of which has the vent opening which is uncovered by peeling back the top layer, after which the product opening is uncovered.

  • Patent number: 5573525
    Abstract: A medicine bottle is formed with a neck that defines an opening and a closed bottom opposite the opening. A closure element is engaged with the neck to block the opening, and the closure element is formed with a fluid passageway. A fitting is positioned in the fluid passageway. The fitting is configured for receiving the hub of a needleless syringe, and a tube which has a proximal end is positioned in the bottle with the proximal end in fluid communication with the fitting. The tube also has a distal end disposed near the bottom of the bottle. Consequently, the syringe can be engaged with the fitting for drawing liquid from the bottle into the syringe without inverting the bottom of the bottle over the neck of the bottle, even when the bottle is nearly empty.

  • Patent number: 5531810
    Abstract: A cap assembly for a gas chromatography injection port includes a two-piece septum. The two-piece septum includes a syringe seal for sealing an injection needle and a duckbill seal for sealing the injection port when the needle is not inserted. The syringe seal includes three annular ribs in its aperture. At the aperture base is a sealing rib that provides the main sealing function for the syringe seal. Just above the sealing rib is a stress-relief rib. At the top of the aperture is a wiping rib. The wiping rib wipes dust on the needle exterior so that it does not enter the aperture. Dust entering the aperture can be retained in the relatively large dust pocket between the wiping rib and the strain-relief rib. The septum is held in place by a septum nut that has a recess above the wiping rib for holding dust removed from the needle by the wiping rib. A washer in the recess prevents the syringe seal from deforming into the recess.

  • Patent number: 5531347
    Abstract: A lid for a disposable hot beverage container that is specifically designed to hold a pastry over the hot beverage. This enables the steam from the beverage to heat, flavor and moisten the pastry. The lid includes an engagement mechanism that enables the lid to be selectively joined to the rim of the hot beverage container. The lid has a plurality of apertures formed through its base structure that enable steam from the beverage to rise through the lid. A plurality of supports extend upwardly from the base structure. The supports all terminate in a common plane a predetermined height above the base structure. The supports hold the pastry a predetermined distance above the base structure of the lid. As a result, if liquid were to spill onto the lid, or if steam were to condense onto the lid, the pastry would be supported above the liquid and would be saved from becoming soggy.
