  • Patent number: 7757893
    Abstract: Bubble device 10 permits a user to directionally disperse a product under compressive pressure toward zone of concern 10Z. Opposed webs 10S and 10C are pressed together to form sealed perimeter 10P around a central enclosure, forming dispersing bubble 12. The perimeter has a breaching seal 10B for product dispersion and a non-breaching seal 10N along the remaining perimeter. Product 10P for dispersion and compressible product transport fluid 12F are contained within the dispersing bubble. The transport fluid is compressed and the force of compression causes the bubble to bulge toward the frangible breaching seal (see FIG. 1C). The web separation occurs inside the dispersing bubble, forcing an edge breach 12E in the breaching seal. The compressed transport fluid rapidly escapes as a released blast through the edge breach. The stored energy of compression within the bubble is released as kinetic energy of the escaping transport fluid.

  • Patent number: 7699191
    Abstract: A multiple use adhesive dispenser facilitates precise, extended dispensing for a surgical procedure by sequentially positioning an ampoule containing a flowable material, such as a polymerizable monomer compound such as a cyanoacrylate adhesive. In one version particularly suited to an open surgical procedure, the ampoules are affixed to a tape substrate that is unreeled from an internal storage reel and transported proximate to an ampoule gripping mechanism with an underlying tape substrate peeled away and internally stored as each ampoule is positioned for dispensing. Actuating an ampoule advancement handle positions the next ampoule and squeezing a movable handle toward a fixed handle effects dispensing. Another version has an elongate shaft that internally augers each ampoule in succession into a pair of spaced jaws that are pinched together by actuating rods to dispense adhesive.

  • Patent number: 7661565
    Abstract: A multi layered frangible seal is bonded over the pour spout opening of flexible plastic bottles containing pourable products such as motor oil. The seal provides a leak proof closure that is strong enough to remain intact when the filled uncapped container is held in an inverted position, and at the same weak enough to break open and dispense the contents into a fill opening when a consumer squeezes the inverted container. The seal is constructed from a first layer of leak proof frangible sheet material that is bonded to a second layer of strengthening sheet material. The strengthening layer contains a cut out void configuration that forms a breaking pattern which forces the seal to break open only in the weaker single frangible layered configuration of the cut out void forming the breaking pattern when the container is squeezed.

  • Publication number: 20020134801
    Abstract: The present invention is a flexible disc-like membrane that is burstable on demand. The membrane is adapted to accommodate an accommodating container (approximately 32 fl. oz.) for automotive type motor oils and other viscous fluids. The membrane serves to contain a fluid content within a container at first use, while the container (with cap removed) is being positioned for pouring and until the consumer manually initiates the membrane to burst so as to release the contained fluid into an engine or other equipment. The present invention improves container content pour-ability by allowing the consumer to manually initiate the release of a fluid content to a free-flowing action at the proper time as to avoid fluid content spillage without the need for the use of a funnel or other pouring assistance.
