Abstract: A tetrahedral-shaped pouch can be opened by tearing from a cut in a first lateral sealing edge and along a longitudinal sealing substantially perpendicular to the first lateral sealing edge to conveniently access non-liquid food contents, such as seeds or nuts. A short longitudinal cut can be made into but not all the way through the first lateral sealing edge, adjacent where the longitudinal sealing is positioned on the first lateral sealing edge. When opening the pouch, by initiating a tear starting at the cut, the packaging material will tear along, but not cross the longitudinal sealing, since the longitudinal sealing is formed from an overlapped and doubly thick section of packaging material. The pouch will therefore open, on at least one side of the tetrahedron, along a predictable tear line following the longitudinal sealing, to form a bowl-shaped receptacle from which the contained food product can be conveniently accessed.

Abstract: A flexible modular construction device comprising tongue portions (26) and flap portions (18) extending from a polygonal body (12). The polygonal body and flap portions have openings (16; 22) which are similar in size and shape, such that the tongue portion can engage said openings simultaneously. Slits (24) between the polygonal body and flap portions allow the tongue of other construction modules to pass through and engage with the openings of overlapping flap and body portions on other modules in an interweaving manner. The margin between body portions, flaps, and tongues is marked with integral hinges (14; 20; 28) which allow the user to assemble stellated forms and other articulated and convertible geometric structures. Accordingly several advantages are to provide an improved construction device, to provide means of increasing the ease of assembling more structurally stable forms, using a more user-friendly and versatile modular construction device.

Abstract: A foldable structure comprised of hinged panel segments is provided. These segments are comprised of a first panel pair comprised of a first and second polygonal panel, and a second panel pair comprised of a third and fourth polygonal panel. Segments are bounded by a first boundary plane defined by two sides of the first panel pair, and a second boundary plane defined by two sides of the second panel pair, Measurement of a boundary angle may be taken normal to the intersection of the first and second boundary planes. As the segment is continuously folded between a first position and a second position, said boundary angle remains substantially constant during folding.

The carton has a non-uniform width. The bottom portion of the carton is narrower than the top portion of the carton, as a result of which the carton, and thus the entire package, complies with a very strict display face dimension limit of the merchandiser.

Abstract: A bait station for containing rat poison contains a housing; at least one opening in the housing for a rat to enter; and a bait position in the housing for locating poisoned bait. A divider is provided between the bait position and each opening to prevent direct access to the bait from the opening, for example by a child. However, there are at least two different routes from the bait position leading to openings. Research has shown that rats, unlike mice, prefer not to eat in a confined space and it is believed that the choice of escape routes offered by the bait station of the invention encourages a rat to eat more of the bait. The bait station may include a hinged lid with locking means to prevent tampering with the bait.

Abstract: The present invention is a pyramid-shaped structure formed of a single sheet of foldable material, such as a sheet of paper. Two embodiments are disclosed. The first embodiment maximizes the amount of volume contained by the pyramid-shaped structure. The embodiment encloses a smaller volume than the first embodiment but maximizes structural strength, or rigidity, of the structure. Each embodiment has certain advantages. The first embodiment can be efficiently created with a minimal number of folds. It can be "collapsed" from a single sheet of pre-creased material to instantly form a structure. It is also easily opened in a single motion. The second embodiment provides an extremely strong pyramid structure that can be formed around an object for complete containment of the object. Other uses are possible such as providing a tent-like housing for a person by cutting an opening in one of the sides.
