Abstract: A fluid delivery device includes a compressible sleeve configured to hold a fluid-holding container such as an ampoule or capsule. The sleeve is compressible so as to be able to shatter the container under user-applied force to release the contents of the container for application to a desired location. The sleeve is constructed from at least two independent and separate walls. The independence of the walls improves the resistance of the sleeve to accidental puncturing by the frangible container while not significantly impacting the force required to shatter the container.

Abstract: The present invention provides a composite panel for use in construction, and particularly for shingling, which comprises natural fiber and a polymer. Due to its composition and layout the construction panel provides all of the advantages of natural materials and high end roofing materials, particularly an attractive appearance, while at the same time allowing for ease of installation, little or no maintenance requirements, and providing superior impact and fire resistance when compared to other roofing materials. The construction panels can also be installed using conventional equipment and methods similar to the installation of 3-tab asphalt shingles with little or no learning curve.

Abstract: A plant protector is positionable about the base of a young tree or other plant. The protector has first and second shells, each formed of a rigid material and having a semi-cylindrical shaped portion and with flanges extending outwardly from and running longitudinally along the semi-cylindrical portions. Each semi-cylindrical portion may have raised circumferential ribs which are spaced apart at regular intervals to increase strength and rigidity. The opposed flanges abut and the semi-cylindrical portions form a cylindrical tube when the shells are engaged together. The shells are locked together by locking structures formed on at least one of the flanges of the shells. The shells may be held together at one edge by a hinge extending longitudinally along edges of the shells. Various locking structures may be used, such as mating bosses and indentations formed on the flanges on opposite sides of the first and second shells.
