The shipping and display box further includes a top panel adjacent to and at an approximate right angle to the first side wall at a second crease line, the top panel comprising a proximal end wall at a proximal end of the top panel and a distal end tab at a distal end of the top panel. In embodiments, the shipping and display box further includes a second side wall adjacent to and at an approximate right angle to the top panel at a third crease line. The bottom panel, first side wall, second side wall, top panel, and proximal end wall each comprise one or more perforations configured to enable removal of sections of each of the bottom panel, first side wall, second side wall, top panel, and proximal end wall for display of contents of the shipping and display box.

A container for housing scented product includes a bottom wall, a top wall, a plurality of longitudinal sidewalls, and a plurality of lateral sidewalls. The container further includes a scented product disposed within the cavity and a first plurality of selectively openable and closable vents extending through the top wall of the container. The first plurality of vents is configured to at least partially open when a force is applied to one or more of the plurality of longitudinal sidewalls and the plurality of lateral sidewalls of the container. The container further includes a second plurality of selectively openable and closable vents extending through the bottom wall of the container. The second plurality of vents are configured to at least partially open when the force is applied to one or more of the plurality of longitudinal sidewalls and the plurality of lateral sidewalls of the container.

A lidding device (102) includes a first panel (104) comprising a lid (106) configured to cover and seal a food container (108). A second panel (110) is foldably connected to the first panel. A third panel (112) includes a bottom panel opposite the lid, wherein the second panel is foldably connected to the first panel and the third panel. A fourth panel (114) is foldably connected to at least one of the first panel and the third panel, wherein the fourth panel and second panel are configured to at least partially enclose a food container between the second and fourth panels.

The invention relates to a device for checking whether a package has been opened or not, comprising at least one package (10), at least one electronic unit (18), at least one battery (12) which supplies the electronic unit (18) with energy, at least one display (14) which can be controlled by the electronic unit (18), said electronic unit (18), the battery (12) and the display (14) being arranged on the package (10). At least two contact tracks (23, 24) and/or electrodes (26, 28) and/or at least one strain sensor (25) are provided as means for detecting whether the package (10) has been opened or not.

The object of the invention is a method for forming containers made of wood or wood fibre preferably for use with fruits and vegetables, comprising at least one base (5) and sides (6, 7), which extend with respect to the base (5), with the aid of first folding lines (3, 4). In a first step of the method, folding lines (3, 4) are defined on the laminar preform, whereon rectangular through holes (1) and non-through incisions (2) are die cut. Finally, the container is folded and the final assembly is performed. Likewise, an object of the invention are containers preferably for use with fruits and vegetables, for commercial or industrial use which are able to be obtained by the previous method.

A blank of foldable sheet material is provided. The blank includes a bottom panel, a first bottom side panel and a second opposing bottom side panel extending from opposing side edges of the bottom panel, and a front panel extending from a front edge of the bottom panel. The front panel includes opposing side edges. The blank also includes a first and a second diagonal panel extending from a front edge of the first and second bottom side panels, respectively, and a third and a fourth diagonal panel extending from each side edge of the front panel. The third and fourth diagonal panels have a length greater than a length of the first and second diagonal panels. The blank includes a first and a second corner panel, wherein the first corner panel is hingedly connected to the first and third diagonal panels and the second corner panel is hingedly connected to the second and fourth diagonal panels.

The invention relates to a method for retrieving a shut state and/or a location of a closable container as well as closable containers, wherein a transition between an open position and a closed position is achieved by a relative movement at least of a first container part with respect to a second container part, wherein the container has at least one RFID chip having a connected near field antenna and a far field antenna and the RFID chip having the connected near field antenna is arranged at the first or at the second container part and the far field antenna is arranged at the other one of the first and second container part, respectively, and the near field antenna, which is connected to the RFID chip, is arranged, as compared to the far field antenna, such that, in the closed position of the container, a noncontact electromagnetic coupling takes place between the near field antenna and the far field antenna. In the context of the method, due to the interaction of a sending unit and a receiving unit, a response signal can by generated by means of the RFID chip and can be transmitted, the range of said response signal depending on the shut position of the container.

The method includes a blank with sidewall panels, a first foot panel connected to a first one of the sidewall panels, a platform panel connected to the first foot panel, and a second foot panel connected to the platform panel, the method including first folding the sidewall panels and connecting respective side edges of the sidewall panels to form sidewalls of a package, second folding the platform panel to fit within a first end of the sidewalls so that the first foot panel and the second foot panel each at least partially press against a respective one of the sidewalls, and connecting the second foot panel to one of the sidewalls to stabilize the platform panel within the first end.
