  • Patent number: 7325703
    Abstract: A single-use, multi-chamber package for housing and common administration of at least two flowable substances. The package includes at least first and second product storage cavities; and at least first and second product application channels. At least one separation line selectively reduces the strength of a predetermined area of the package and generally defines a tab. Steps of use include: 1) applying a force to tab creation areas to separate a portion of a tab; 2) removing the tab from the blister package by tearing across the product application channels to form wings, exposing the interior of the product application channels; 3) rotating the wings to pivot the channel openings toward one another, and 4) applying a force to the storage cavities to dispense the products. The package may contain more than two substances by employing multiple storage cavities and application channels.

  • Publication number: 20070151893
    Abstract: A shielded medication package including a blister portion and a blister shield attached to a backing substrate. Accessing a medicament is easy for an adult to accomplish, yet the package resists children biting and picking at the blister portion. The blister portion contains a base layer and a blister layer. The blister layer includes an article receiving blister designed for holding the medicament. A blister shield overlays the blister portion. The blister shield includes a blister well that cooperates with the article receiving blister. The blister shield protects the article receiving blister from substantially lateral forces. To eject the medicament, application of a substantially orthogonal force to the article receiving blister is required.

  • Publication number: 20070080090
    Abstract: A child-resistant medicament storage and distribution back card for senior-friendly and child-resistant distribution of a medicament. The back card is incorporated into a medication package where it protects the area of the package that is most susceptible to attacks on the integrity of the package. The back card has a card opening feature bounded by a perimeter that includes at least two cuts and at least two lands, often thought of as perforations. The cuts extend through the back card, and the lands connect the back card to the card opening feature. Each cut has a cut length and each land has a land length. The ratio of any land length to any cut length is between approximately 0.25 and approximately 0.

  • Patent number: 5413441
    Abstract: A hybrid eccentric wedge anchor includes a cylindrical anchor body, an eccentric wedge unit, and cylindrical leading end. The eccentric wedge unit includes a tapered body, a shoulder between the tapered body and the anchor body, and a crescent shaped clip rotatably positioned around the tapered body. The longitudinal axis of the tapered body is different from the longitudinal axis of the anchor body. The shoulder varies in width around the circumference of the anchor body. As the crescent shaped clip rotates around the tapered body, its outer circumference varies from being flush with the outer circumference of the cylindrical anchor body to extending beyond the outer circumference of the cylindrical anchor body.The hybrid eccentric wedge anchor can be configured in many useful anchor forms having the eccentric wedge unit. Examples include, but are not limited to, expansion bolt or drop-in configurations.

  • Patent number: 4700854
    Abstract: A slackless draw bar coupler arrangement in which the car has a draw bar pocket with an open top, a slotted draft plate and a buff plate and the draw bar has a bar body with a spherical head connected to the body by a neck. Located about the neck is a thrust ring for disposition between the draft plate and the head and at that side of the head remote from the neck, there is a thrust disc insert for disposition between the buff plate and the head. The thrust disc insert and thrust ring are carried in holders. Between the buff plate and the thrust disc insert is a removable wedge which is spring loaded to urge the thrust disc insert firmly towards the head of the draw bar.
