A sack includes a flexible sack body and a mouth that includes two separable lips that form a mouth opening when the lips are separated from one another, and that close the opening when the lips are adjacent to one another. Closing structure is configured to enable a separating force that is applied to the lips to separate the lips from one another to form the mouth opening, and to bring the lips adjacent to one another to close the mouth opening in the absence of the applied separating force.

A photovoltaic module packing box and a photovoltaic module package structure are provided. The photovoltaic module packing box includes a tray having an accommodation space; a support plate having an edge hinged to an edge of the tray, and the support plate is lapped on the tray; an airbag assembly arranged in the accommodation space; an air valve assembly connected to the airbag assembly by a pipeline; an enclosure frame connected to the support plate and configured to enclose, together with the support plate, a receiving space for photovoltaic modules, and the enclosure frame includes a fixation part and a movable part; the fixation part is fixed to the support plate with one side thereof configured as an open structure; the movable part is detachably connected to the open structure of the fixation part, and the movable part and the fixation part together form an annular structure.

Systems and methods for retention and access to storage containers, including a flexible sidewall that is configured to be removably attached to an open side of a storage container. A retention and access system may be configured to be repositioned to increase a size of an opening into the container in order to access items stored lower down within the container.

The present disclosure is directed to containers comprising one or more magnets such that the containers, when placed adjacent to one another, may be magnetically coupled together.

A container assembly is provided with a container and a lid, with the lid cooperating with the container to enclose the interior of the container. A magnetic member is supported by the lid or the container for transverse movement between a first position and a second position. When the lid is cooperatively associated with the container, the magnetic member is in the first position and inhibits movement of the lid along a longitudinal axis of the container to lock the container. With the magnetic member in the second position, the lid is moveable along the longitudinal axis to open the container.

Embodiments of a magnetic holder that utilizes a magnet to attach a bottle or other object to a ferromagnetic surface are disclosed.

A bottle carrier for use with a bottle is disclosed. The bottle has a screw cap. The bottle carrier has a diameter of at least two inches. An internally threaded socket has a solid ceiling and a perimeter. The internally threaded socket receives an externally threaded bottle top of the bottle. The bottle carrier replaces the screw cap. At least two apertures in the bottle carrier receive a handle. The apertures extend through the bottle carrier beyond the perimeter of the internally threaded socket. A handle engages the bottle carrier through at least two apertures of the bottle carrier.

A system of packaging and displaying a set of products is disclosed. The system may include a first and second container, together forming a hinged box, each container including a first display face, and a first back positioned on a side of the container opposite the first display face. A first magnetic element and a second element magnetically responsive to the first magnetic element may be positioned in the containers to assist in closing the box. At least one of the containers includes a transparent cover that secures, even in the open position of the box, displayed products, the displayed product visible through the cover when the box is hinged open. The cover has perforations that can be torn to access the products without tools. The products are arranged in the order of use and installation.

A packaging container for bulk solids includes a container body, a container lid and a locking arrangement. The container body comprises a container wall that defines a container opening and an inner compartment. The container lid comprises a peripheral portion at a peripheral edge of the container lid. The container lid is joined by a hinged connection to the container body at a rear edge portion of the container opening. The locking arrangement comprises at least one locking tab permanently joined to the container body at a front edge portion of the container opening and/or at an opposing side edge portion of the container opening. The locking tab comprises a free end portion extending in the height direction. The free end portion of the locking tab comprises a first locking element arranged to mate with a second locking element arranged on the peripheral portion of the container lid.

A retail product package is disclosed. The package comprises an outer sleeve and an inner tray that is configured to slide in and out of the sleeve. The sleeve and tray being constructed and configured to be magnetically attracted to one another to facilitate and maintain a closed packaging configuration. Windows on the sleeve and tray allow for inspection of the product contained therein, which is mounted via a support element in a fixed position removed from contact from the packaging walls. A hook component is provided on the tray that is configured to extend through a top end wall of the sleeve and facilitate display of the package on a peg in a retail display stand.
