With Rupture Means For Access Patents (Class 206/532)
  • Patent number: 5310060
    Abstract: The present invention concerns a novel tamper-evident, child-resistant blister package for medicaments and nonmedicaments which is user-friendly, but which is difficult to open by young children and impaired adults.Because the blister package has pull tabs which are designed to be pulled away from, rather than towards, article-receiving pockets which may be present in the blister package other than the article-receiving pocket being accessed, a young child or user of the blister package can only access one article-receiving pocket at a time, whether deliberately or inadvertently.The blister package of the invention is an attractive and inexpensive package for the merchandising of pharmaceutical and other products which is constructed in a manner which facilitates mass production.

  • Patent number: 5288159
    Abstract: A liquid applicator is provided which is particularly useful in applying preoperative surgical scrubs or paints to skin. The liquid is contained in a frangible ampoule inside the body of the applicator. This ampoule is supported and protected by a deformable element that prevents unintentional breakage of the ampoule from impacts during storage and handling before use. The applicator is actuated by pushing at least a portion of the frangible ampoule through an aperture in the deformable element and into contact with a means for breaking the ampoule.

    Abstract: A child-resistant blister pack for fragile single-dosage forms, e.g. a fast-dissolving dosage form ((FDDF) is disclosed. Limited entry points are provided, and completion of a sequence of steps is necessary to access the dosage forms within the depressions. A blister film sheet with depressions for receiving dosage forms is sealed with a lidding sheet and perforated to provide lines of weakness to define single dosage units with a depression containing a dosage form in each dosage unit. Single- or double-entry embodiments are disclosed, allowing access from one or two points on the blister sheet. After tearing along the perforations, a single dosage unit is separated from the blister pack. The user may then access the single-dosage form in the associated single-dosage unit. In a first embodiment, the dosage unit has a tear strip for exposing an unsealed corner, thereby allowing access to the dosage form within by grasping the edge and peeling it off the blister film sheet.

  • Patent number: 4782967
    Abstract: A system for simultaneously rupturing and carrying away a breakable foil seal and packing from a medicine vial or other container which incorporates a string attached to the foil seal with one end exterior of the foil seal and the other attached to the packing. The exterior end serves as a pull tab or can be attached to another item which serves the same purpose. When pulled, the string first ruptures the foil seal, then carries it away along with the packing. The pull tab may be length of string, additional foil layers of the seal or the vial lid. The system is designed to facilitate access to the contents of the vial by individuals lacking dexterity due to age, illness or amputation.

  • Patent number: 4588090
    Abstract: A blister pack strip comprises two congruent deep-drawn carrier foils (1) of polystyrene. Each foil (1) has a thickness of between 130 and 190.mu.. The foils (1) are coated on their facing surfaces with polyethylene (2) having a thickness of between 40 and 50.mu., are welded together in mirror image to form a plurality of pockets (7), and define a plurality of inlet funnels (4) along one edge of the strip communicating with respective pockets. Each inlet funnel (4) is at least partly closed by a weld bridge (5). Welded-up squirt nozzles (8) communicating with each pocket (7) are formed on the side of the strip opposite to the inlet funnels (4), and a groove (9) is provided transversely to the squirt nozzles (8) and parallel with the adjacent edges of the carrier foils (1).

  • Patent number: 4567986
    Abstract: A unit portion pack is made from two webs, at least one of which is a laminate (2) having layer (4) of tear resistant material, such as polyester film, and a layer (6) of rupturable material, such as aluminum foil. The two webs (2, 26) are bonded together by way of heat seals, (38, 40) to define a plurality of cavity-forming regions (34) in each of which a single pill (36) or other solid product item is received. A longitudinally extending score or slit line (10) extends along each longitudinally arranged row of regions (34) inwardly of the peripheries of the regions. The pill (36) is released by manipulating the pack such that the score or slitline is located on or outboard of the periphery of the pill by movement of the latter. The area of the cavity-forming region on the other side of the score or slit line to the pill is then squeezed to fracture the rupturable material at the score or slit line. This forms a dispensing opening through which the pill may be pushed.
