| 20090230081 | VENTED SCREWCAP CLOSURE WITH DIFFUSIVE MEMBRANE LINER - A liner for a wine bottle cap is constructed such that a gas, such as oxygen, that diffuses through the liner moves along a path within the liner whose length is greater than the thickness of the liner. In this manner, oxygen from the atmospheric air can diffuse through a relatively thin liner at a slow rate before reaching the bottled wine. The liner is comprised of alternating layers of material semi-permeable to oxygen and material impermeable to oxygen, the impermeable layers containing open areas through which oxygen can diffuse. As oxygen diffuses through the alternating layers, the path(s) along which the oxygen diffuses is determined by the locations of the open areas in the impermeable layers. The liner may be assembled with a screw cap closure that comprises ventilation holes connected by a raceway for distribution of atmospheric air to the liner. | 09-17-2009 |

| 20140339191 | Specimen Collection Container System - A specimen collection container having an improved sealing mechanism that provides enhanced sealing properties during transport, storage, and handling. The specimen collection container comprises a cup, cap and improved sealing mechanism. The sealing mechanism forms multiple seals between the cup and cap. In a preferred embodiment, the sealing mechanism forms primary, secondary and tertiary seals between the cap the cup. The primary and secondary seals are preferably formed between the cap and the interior surface of the cup. The tertiary seal is preferably formed between the cap and the distal edge of the cup. The first, second and third seals are sequentially formed as the cap is rotated from a first radial position at which the threads first engage each other to a second radial location at which the cap is fully closed. Each of the three seals on its own is capable of sealing the container and preventing a fluid specimen from leaking from the cup if the seal is maintained. The primary and secondary seals are constructed and arranged to seal the cup after the cup and cap are threadingly engaged independent of the amount of torque applied to the cap. | 11-20-2014 |

| 20090289027 | MEANS FOR SEALING BOTTLE CAPS WITH EVIDENCE OF OPENING - The present invention consists of an improvement made on the patent “Means for sealing bottle caps with evidence of opening” with Spanish application number P200202864, which made use of a concealed tongue that was revealed after the first opening without allowing to recover the original situation. The present invention maintains a connection between the top and bottom segments of the capsule, preventing their rotation relative to each other and providing an audible evidence of opening. | 11-26-2009 |
| 20120187074 | Child resistant cap with safety collar and enhancement - A child resistant cap includes: (a) a main closure base; (b) an outer ring that functions as a safety collar; (c) a dispensing mechanism on the base; (d) an overcap. The base attaches to a top dispensing container and the horizontally rotatable ring is attached to the base. The overcap has protrusions and the ring has corresponding cut outs. Because the overcap and ring are frictionally engaged, when one rotates, the other rotates with it. They must be held separately and rotated relative to one another to effect proper alignment for overcap remove and container dispensing. In some embodiments, the base is eliminated and the ring is attached directly to a container rim. | 07-26-2012 |
