  • Patent number: 9067714
    Abstract: A device (1) is proposed which consists of a pouring nozzle (2) with a cylindrical circumferential wall (20) and with an internal thread (21) and a terminal flange (22), into which an adapter (3) can be screwed. The adapter (3) has an inlet end (30) with an external thread (32) and an outlet end (31) with a conical tube attachment (35). At least one combined perforating and cutting tooth (34) is formed integrally on its lower edge in the screwing-on direction. In order to achieve as high a sealing force as possible between the tubular bag (4) and the adapter (3), a special seal is proposed. To this end, the cylindrical circumferential wall (20) above the terminal flange (22) is guided into a double-walled region. The outer region forms an obliquely outwardly directed conical supporting-wall region (24) and the inner double-walled region (23) is formed by a likewise slightly conically designed but inwardly directed sealing skirt (25).

  • Patent number: 8109236
    Abstract: Assemblies in accordance with the invention can lead to an exceptionally easy to use, safe, and convenient system and method of applying a fixed dosage of chemicals to which a user might wish to avoid contact, such as parasiticides. In the present invention, a fluid, such as a pesticide or parasiticide, glue, solvent, lubricant, medicament and the like is loaded into a fluid reservoir and the reservoir sealed. The reservoir can be attached to a cap-applicator structure which is in an inactive configuration. In the inactive configuration, a piercing tip remains poised over the reservoir in an inactive configuration without forming an opening in the reservoir. The cap-applicator can have a sharp intsernal piercing tip capable of piercing the reservoir when the assembly is converted into an active configuration. This will allow the user to dispense the liquid out of the reservoir through the applicator.

  • Patent number: 7503142
    Abstract: The insertable pest catching device is an invention that because of its unique geometry and design provides for the simple and cost effective catching of pests such as hornets and yellow jackets. The device is principally intended for use in combination with an empty plastic two-liter volume soda pop bottle. In practice, an attractant such as a predetermined amount of sugar water is placed into a capped plastic bottle and the funnel shaped device is retentatively pressed into the side of the bottle. The device in combination with the bottle creates an attraction to pests. The pests are guided into the bottle through the funnel and subsequently die within the bottle. After a predetermined quantity of pests are trapped within the bottle, the bottle, with the device still inserted may be discarded as an entire assembly. Thus the disassembly, mess, and washing common with prior art pest catching devices are avoided. In certain embodiments, multiple devices may be inserted into a single bottle.

  • Patent number: 4653669
    Abstract: A molded plastic container comprises an outer container having a first end wall portion. A tubular member extends from end to end through the interior of the container. The end wall portion defines a first annular area of weakness, the tubular member communicating with the end wall adjacent the first annular area of weakness. The user may apply longitudinal pressure on the end of the tubular member opposite to the end wall to rupture the first annular area and to permit the tubular member to slidingly advance out of the container interior through the ruptured area of the end wall, to serve as a pouring spout.

  • Patent number: 4322018
    Abstract: A fluid dispenser for a bulk container of the type having a rigid outer box with a sealable flexible plastic inner bag. The dispenser includes a tubular sleeve having a flange that is heat-sealed to the outer surface of the plastic bag and a tubular turncock having a pointed inner end for piercing the bag of fluid. Extending from the tubular surface of the turncock barrel are keys that engage keyways in the bore of the tubular sleeve that both restrict longitudinal movement of the turncock to prevent removal or bag-piercing during storage and shipping and also, after the turncock is fully inserted to pierce the bag, restricts rotational movement of the turncock to prevent accidental removal and possible leakage. A second embodiment of the invention replaces the turncock with a conduit having the keys and the pointed tip, but with a tube fitting at the opposite end for dispensing the fluid at a remote valve or pump.
