  • Patent number: 7160054
    Abstract: An expanding grass or weed inhibitor around a growing tree or shrub trunk with a series of overlapping, semi-circular wings (16) attached to the base (10), rotating via multiple pivot bolts (18). With an expanding trunk (14) diameter, the pressure of the trunk forces the semi-circular winds to move away from the trunk. Due to the overlapping of the semi-circular wings, their mutually-applied pressure blocks sturdier grass or weeds from uplifting the wings (16) or permeating the base (10). Along the perimeter of the base (10), a barrier wall (12) prevents the semi-circular wings from rotating too far respective to the trunk (14). For the purpose of mounting, base (10) pivots via a pivot bolt (18) while opening along slit at pivot side of base (26). On the opposite side of the base (10), slit at opening side of base (24) opens to account for a wide range of trunk diameters. To secure the base (10), lockable bolt (20) transects a hole connecting to lockable bolt (22).

  • Patent number: 6272792
    Abstract: A hollow, bottomless container for shipping and displaying plants. The container is formed of an elongate, rectangular strip of a resilient material that is folded into a triangular sleeve in which a seed ball is placed. The container is formed such that pressure exerted by the seed ball on the side walls of the container does not cause the container to open, but serves to hold the seed ball within the container, negating the need for a bottom surface on the container. The container may also include printed matter on the exterior of the container, as the resilient strip forming the container is also printable.
