  • Patent number: 5249695
    Abstract: For tent-type paperboard containers as well as other containers, a spout fitment is attached surrounding a hole in the container. The fitment spout has internal threads and an external flange which seals around the hole and is fixed to the container by thermal means, adhesive or the like. The cap has a top disk from which an externally threaded skirt depends. The exterior of the skirt has gripping ribs to assist in screwing and unscrewing the cap. The lower edge of the skirt seals against a sealing membrane on the spout. Surrounding the skirt is a tamper-evident band attached to the lower edges of the ribs by frangible bridges. The tamper-evident band has locking means engaging complementary locking means on the fitment. Thus, the cap cannot be unscrewed without removing the tamper-evident band. By unique design, the fitment and cap may be molded in one mold cavity.

  • Patent number: 5137182
    Abstract: The end closure for the nozzle orifice of a dispensing cartridge for a two-component or multi-component system has at least two parallel stoppers which project from a common base and fit into the adjacent dispensing canals in the nozzle tube of the cartridge. For securing the closure to the cartridge in an axial direction, anchoring devices are provided to engage in the cartridge, such as lugs that permit elastic deformation, fitted with hooks or holding cams. At the junction with the base, each stopper has a continuous peripheral fillet. This acts conjointly with the edge of the orifice of the corresponding dispensing channel. The closure forms a secure seal for long-term storage and transport of the cartridge, is easy to use and inexpensive to make.

  • Patent number: 5133479
    Abstract: A container for a liquid which is to be poured out of the container through an open neck, is internally provided with a buoyant stopper for the neck. The stopper is oriented, by uneven weight distribution, to float in a stop surface up, flexible tabs down orientation. In use, the container, after being opened, is slightly squeezed to elevate the stopper stop surface into sealing engagement with the neck. In this condition, the container is inverted and its open neck placed over the intended receiver, whereupon manual squeezing is relaxed, allowing the stopper to bob up towards the bottom of container. Inversion, while bobbing up desirably orients the stopper so that, as the stopper settles into the container shoulder or neck during emptying, it cannot undesirably replug the container neck. The stopper can be inserted into the container during the container manufacturing process, by flexing the tabs and forcing the stopper into the container through the neck, tab end first.

  • Patent number: 5121859
    Abstract: A non-resealable dispenser cap construction having an elongate tapered, stepped hollow spout member with an exterior shoulder intermediate its ends, and a discharge orifice. A closure cap member having a transverse closure wall is mounted on the spout member with the transverse wall engaging and closing over the discharge orifice. With the closure cap member so mounted, the transverse closure wall is distorted and biased by its engagement with the wall of the discharge orifice. One of the members is formed with two oppositely-disposed frangible tabs which overlie and are permanently attached to the other member, and each tab has a zone of weakness which can be readily ruptured upon the application of opposing rotative forces to the members. With the cap member removed the orifice is exposed, permitting discharge of the container contents through the spout member. Re-sealing of the cap member on the spout member is prevented, due to a lack of interengageable parts on the two members.
