PCT No. PCT / US96 / 20932 Sec. 371 Date Jun. 30, 1998 Sec. 102(e) Date Jun. 30, 1998 PCT Filed Dec. 23, 1996 PCT Pub. No. WO97 / 25085 PCT Pub. Date Jul. 17, 1997The present invention relates to polymeric medical articles comprising the antiinfective agents chlorhexidine and triclosan. It is based, at least in part, on the discovery that the synergistic relationship between these compounds permits the use of relatively low levels of both agents, and on the discovery that effective antimicrobial activity may be achieved when these compounds are comprised in either hydrophilic or hydrophobic polymers. It is also based on the discovery that chlorhexidine free base and triclosan, used together, are incorporated into polymeric medical articles more efficiently. Medical articles prepared according to the invention offer the advantage of preventing or inhibiting infection while avoiding undesirably high release of antiinfective agent, for example into the bloodstream of a subject.

Insulated beverage or food container
InactiveUS6852381B2Reduce energy transferImprove functionalityWrappers shrinkageRefuse receptaclesEnergy transferEngineering
An insulating beverage or food container or sleeve is produced with a foam layer disposed on an inner surface of a paper stock. A polymer shrink film layer is arranged in a position along an inside surface of the beverage container. The foam layer is sandwiched between the polymer shrink film layer and the paper stock and decreases the energy transfer between the beverage and the user's hands allowing the user to hold onto the container for an extended period of time without causing user discomfort or pain. The polymer shrink film layer is produced from a shrink film polymer having a percent shrink in the range of 30% or less, and more particularly a percent shrink range of 5 to 10%.

Method for dispensing a predetermined amount of film relative to load girth
The present invention provides a method and apparatus for dispensing a predetermined fixed amount of pre-stretched film based upon load girth. A non-rotating ring carries a belt. A film dispenser is mounted on a rotating ring, and the rotating ring includes a pulley that connects to the belt. Based upon the girth of the load to be wrapped, an amount of pre-stretched film to be dispensed for each revolution made by the rotating ring is determined. Good wrapping performance in terms of load containment (wrap force) and optimum film use is obtained by dispensing a length of pre-stretched film that is between approximately 100% and approximately 130% of load girth. Once the amount of film to be dispensed per revolution is determined, a mechanical ratio of ring drive to final pre-stretch surface speed (i.e., number of pre-stretch roller revolution / ring rotation) can be set. Thus, for each revolution of the rotating ring and dispenser, a predetermined fixed amount of film is dispensed and wrapped around the load.

Low-odor single element equipment grip
A low odor grip is disclosed for a handle of a hand-held implement such as a sports implement or a manual or electric tool which is essentially free of disagreeable odors, which can be installed and quickly shrunk into a tight vapor resistant grip within a matter of a few minutes rather than requiring extended periods of time, and can be installed without the need for any application of heat or use of special tools, equipment or materials. The present device is therefore easy to install, merely sliding over the handle while in dilated state and then allowed to shrink and set by evaporation of the solvent, and thus can be satisfactorily installed in both fabrication facilities and in the field either as an original or replacement grip. The invention also includes an implement fitted with such grip. Representative implements include sports implements such as golf clubs, tennis racquets, weight bars and fishing poles, as well as tools such as hammers, drills, pliers, shovels, axes, and the like. The grip is preferable made of a swellable elastomeric material, preferably a natural or synthetic rubber. Suitable rubbers include EPDM rubber, neoprene or chlorosulfonate polyethylene (Hypalon(TM)) rubber, of which EPDM rubber is preferred.

Hybrid palletizer
ActiveUS8074431B1Increase speedShorten the timeWrappers shrinkageSolid materialIndividual itemRobotic arm
The present invention relates to compact palletizers that include a stretch-wrap operation as the pallet is built. Specifically, the present invention uses a robot to place items from a fixed infeed elevation either above or, alternatively, below the height of the finished load. A four-sided compression mechanism compresses the rough-built load to the final pallet size and then the entire layer is released to the pallet.Individual items or group of items are picked and placed onto a layer support device in a loose orientation. The loose orientation enables a much faster palletizing operation because the robotic arm that pick-and-places the item, the items, or the row of items, can travel much faster as it does not have to precisely locate the item, items, or row of items. During the time that a layer is being loosely constructed on the layer support device concurrent wrapping can occur.

Ring wrapping apparatus including metered pre-stretch film delivery assembly
The present invention provides a method and apparatus for dispensing a predetermined fixed amount of pre-stretched packaging material based upon load girth. A non-rotating ring carries a belt driven by a motor. A packaging material dispenser is mounted on a rotating ring, and the rotating ring may include a pulley that connects to the band, such that the rotating ring is driven by the drive belt. Based upon the girth of the load to be wrapped, an amount of pre-stretched packaging material to be dispensed for each revolution made by the rotating ring is determined. Good wrapping performance in terms of load containment (wrap force) and optimum packaging material use is obtained by dispensing a length of pre-stretched packaging material that is between approximately 90% and approximately 120% of load girth. Once the amount of packaging material to be dispensed per revolution is determined, a ratio of rotating ring drive to final pre-stretch surface speed (i.e., number of pre-stretch roller revolution / rotating ring rotation) can be set and mechanically controlled. Thus, for each revolution of the rotating ring and dispenser, a predetermined fixed amount of packaging material is dispensed and wrapped around the load. In an alternative embodiment, the ratio is electronically controlled.

A product packaging comprises a cap on a transparent bottle to seal in a protected product. The cap includes an RFID chip and antenna that can report a serial number and product identification code to a nearby scanner. Reports from several such scanners in the distribution chain from manufacturer to retailers are logged and used to validate legitimate products by their movements. The caps are designed such that when opened the RFID antenna will break away from its associated RFID chip. The cap is molded of cross-linked polymers with a memory that makes it impossible to reseat it properly to the bottle once removed. A hologram target is placed backwards under a label on the side of the bottle so a laser beam can be directed through the backside of the bottle, through the contents, and to the hologram. The reflected laser light will have a signature that is very sensitive to the exact chemistry of the contents. Adulterations and fake products substituted for the genuine articles inside the bottle are detectable using non-invasive hologram reflected laser light and analysis.
