  • Patent number: 11866236
    Abstract: The disclosed systems and methods relate to improved tamper-proof cases for securely storing and shipping products. A case can include a back panel, two sidewalls, an upper foldable section, and a lower foldable section. The features of the case can be manufactured on a single sheet of material. The upper and lower foldable sections include panels having apertures for holding the top and bottom of a product, respectively. The upper foldable section includes one or more fasteners that secures the upper foldable section to the sidewalls. Once secured, the products cannot be removed from the case without showing evidence of the removal. The case systems can also include one or more inserts, for example an upper insert and a lower insert, to provide additional structural support to the case and protection for the products stored therein.

  • Patent number: 11492173
    Abstract: The disclosed systems and methods relate to improved cases for securely storing and shipping products. A case can include a back panel, an upper foldable section, and a lower foldable section. Each of the features of the case can be manufactured on a single sheet of material. The upper and lower foldable sections include panels having apertures for holding the top and bottom of a product, respectively. The case is foldable into a closed configuration such that a lower holder panel, a lower front panel, and a bottom panel form a lower box configured to hold the bottom of the first product, and an upper holder panel, an upper front panel, and a top panel form an upper box configured to hold the top of the first product.

  • Patent number: 8309188
    Abstract: A pull up artificial tree system is adapted to change from a collapsed storage state to an expanded operable state. The pull up tree system includes a base system, a trunk, and a first tree assembly. The first tree assembly includes a top portion; a plurality of frame assemblies comprising a collar, a plurality of outwardly extending support braces, a perimeter, and branch assemblies; and a connection assembly. The collars are slidably disposed upon the trunk, such that they can be pulled upwardly. The pull up tree system can support a regularly arranged artificial tree and/or an inverted tree. In addition, the pull up tree system can be stored in a shell that is slidably disposable within a storage container.

  • Publication number: 20090188845
    Abstract: A cleaning system container includes a base, a side wall, a viewing portion in communication with the side wall, and a cleaning system. The viewing portion is a porthole of the side wall, which provides a window-like mechanism permitting one to see into the cleaning system container through the side wall. The cleaning system container defines a hollow cavity and is capable of holding a fluid, which can receive the cleaning system. The cleaning system container can include a filter assembly and/or a skimmer assembly. By positioning the portholes in desired locations, the amount of waste captured by the filter assembly can be ascertained without the need of opening the cleaning system container, prompting swimming pool owners to change the filter cartridges more frequently, which can improve its overall performance.
