Gerhard H. Weiler has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20020066748
    Abstract: A hermetically sealed container and a medicament bearing insert assembly therefor are disclosed. The medicament bearing insert assembly is protected by a severable overcap. A pocket within the insert assembly is provided with a pierceable membrane. Rupture of the membrane by a built-in plunger causes the medicament to drop out of the pocket and into the container where it is mixed with the container contents.

  • Patent number: 6381926
    Abstract: A hermetically sealed container is provided with a dispensing nozzle terminating in an aperture surrounded by locking lugs. A removable closure portion unitary with the dispensing nozzle and delineated by a frangible web that circumscribes the opening is provided as well so that the closure portion may be severed from the cap portion at the frangible web. An apparatus for fabricating such container is provided which includes a main mold assembly for molding the container body and dual seal mold assemblies for molding the container cap portion and container closure. The main seal mold assembly includes a top surface having a knife edge and an annular cavity. After the main seal mold assembly is closed during the molding process, a forming assembly including a mandrel is extended through the parison into abutting contact with the parison over the top surface of the main seal mold assembly.

  • Patent number: 6379142
    Abstract: A liquid container includes a drop dispensing tip with a hollow stem which defines a liquid passageway and an interior partition wall in the passageway. The partition wall separates the liquid passageway into an upstream chamber and a downstream chamber. Flow communication between these two chambers is provided by a liquid passage in the partition wall. The liquid passage guides liquid against an impingement surface in the downstream chamber from which the liquid is dispensed dropwise.

  • Patent number: 6247616
    Abstract: A cap equipped with a dispensing nozzle is provided for use with a hermetically sealed container which includes a body portion and a neck portion sealed by a pierceable membrane. A spike within the cap pierces the membrane when the cap is threaded onto the neck portion of the container so as to provide access to the contents of the container. The spike includes a passageway in fluid flow communication with a dispensing nozzle on the cap so as to allow dispensing of the contents of such container. In one cap embodiment, the draining spike is an element nestable within the cap which is made of a relatively harder material than the cap. In another cap embodiment, the draining spike is unitary with the cap and made of the same relatively harder material as the cap. A flip top assembly is also provided including a flip top which covers the dispensing nozzle to seal the cap. The flip top is retained on the dispenser by a flexible arm which is unitary with the cap or with a ring.

  • Patent number: 6068148
    Abstract: A hermetically sealed, molded thermoplastic dispensing container is provided which includes a nozzle having a resilient and unitary annular bead about the periphery thereof. The nozzle is sized to receive the hub of a dispensing assembly in a mating relationship and the bead provides a secure friction fit and liquid seal between the hub and the nozzle. The method of forming a container with a nozzle having such a bead includes the use of seal molds having a groove conforming to the shape of the bead and a vacuum passage in communication with such groove and the step of creating a vacuum through the passage and the groove to pull a portion of a parison into the groove to form the bead.
