FIELD OF THE INVENTION
The present invention relates to packaging, in particular for flowers, chicks and the like.
BACKGROUND OF INVENTION
European Patent 3083424 describes a shipping assembly for agricultural products, which includes sets of columns and girders connected together to form a frame. An envelope including a flat foldable material is affixed to the frame. The envelope determines a distance between the columns. The envelope is adapted to hold therein flowers.
SUMMARY
The present invention seeks to provide further developments to the shipping assembly of European Patent 3083424, as is described hereinbelow.
For example, the invention uses a frame made of folded material such as corrugated carton or hard board carton, instead of plastic. This change in materials eliminates the need for plastic components of the frames which require additional care from the unpackers; plastic also has higher costs in comparison to standard carton boxes. The present invention addresses the growing awareness to reduce plastics usage, even when it is possible to dispose of the carton in sustainable manners such as recycling, as done with empty cartons.
The invention addresses the environmental concern by reducing the weight-to-volume ratio of the package and allowing for packing a higher pack rate in comparison to standard cut-flowers shipping boxes. This translates directly in reducing the carbon footprint of the product. In comparison tests between this invention and regular boxes of the same volume, a difference of up to 18% was found in weight of packaging materials per stem, reducing the carbon footprint accordingly.
The present invention also introduces the ability for inner strapping of the flowers by use of straps or rubber bands.
The upper lateral part of the frame is used as ergonomic handles and allows for keeping the flowers within stable and not shifting during handling.
BRIEF DESCRIPTION OF THE DRAWINGS
The present invention will be understood and appreciated more fully from the following detailed description taken in conjunction with the appended drawings in which:
FIG. 1 illustrates member A representing the vertical part of the frame.
FIG. 2 illustrates member B of the frame representing the lateral part of the frame.
FIG. 3 illustrates the assembly of members A and members B to form the full frame.
FIG. 4 illustrates the assembled frame with bases (3) of member A folded and protrusions (5) of member A extending away from the frame.
FIG. 5 illustrates frame positioned into a box having a plurality of openings (1) in which the protrusions (5) of the frames fit.
FIG. 6 illustrates lateral members with different notches or slits to help stabilizing the bunches of flowers in the box.
FIG. 7 illustrates another way to stabilize the bunches.
FIG. 8 illustrates the completed box.
FIG. 9 illustrates plurality of superposed boxes.
DESCRIPTION OF EMBODIMENTS OF THE INVENTION
FIG. 1 shows member A representing the vertical part of the frame. It consists of a folded core (1), made of corrugated carton or other foldable material, forming a hollow center (2) along the entirety or a portion of the core. The base (3) at the bottom of the folded core (1) folds along line (4) to reach a perpendicular position to the core. The base has two protrusions (5) found above the folding line (4). When the base (3) is folded along (4), these protrusions (5) extend out from the folding line to form anchors that will hold the frame steady in a predefined position in the box (as will be further shown in FIG. 5).
FIG. 2 shows member B of the frame representing the lateral part of the frame. It consists of a flat strip of corrugated carton (or other foldable material) (6) which can be folded further along itself to obtain a stronger lateral. When the strip is folded along lines (7), two shorter folds (tabs) (8) are formed.
FIG. 3 shows the assembly of members A and members B to form the full frame. Parts (8) of member B will be inserted in the hollows (2) of columns A.
FIG. 4 shows the assembled frame with bases (3) of member A folded and protrusions (5) of member A extending away from the frame.
FIG. 5 shows the frame positioned into a box having a plurality of openings (1) in which the protrusions (5) of the frames fit and keep the frame in at a fixed distance from each other and from the extremities of the box.
FIG. 6 shows that the laterals can be equipped with different notches or slits to help stabilizing the bunches of flowers in the box. For example, notches (1) can be used to stretch rubber bands (2) between top and bottom laterals to apply moderate pressure on the bunches inside the frames. Further stabilization is obtained by the friction between the rubber bands and the bunches.
FIG. 7 shows another way to stabilize the bunches, with slits situated at both extremities of the lateral. A plastic strap (2) is threaded through the slits of the lower lateral, tightened around the bunches and kept tight with a buckle. Threading the strap around the bunches and the bottom lateral enables more reliable tightening compared to regular boxes wherein the strap is threaded through the side walls of the box and tear the carton when tightened, resulting in loosening the tension of the strap and thus voiding the procedure.
FIG. 8 shows the completed box. Two straps (1) are tied around the box at the level of the frames assuring that the lid (2) and the frames inside the box are securely held in place. Holding the box is done through two dedicated openings in the lid (3). The User inserts his fingers through the openings into the box and under the top laterals. When lifting, the straps (1) do not allow the top lid to move up, nor the top laterals (B) to dislodge out of their hollows in columns (A). This allows for safe lifting of the box in its full and maintaining it in horizontal position to avoid possible shifting of the bunches.
FIG. 9 shows a plurality of superposed boxes. Thanks to the positioning method described in FIG. 5, the columns (A) are all aligned exactly one on top of another, thus forming a line along which the load of all the boxes is distributed evenly, removing the stress from the side walls of the boxes and diverting it to the frames. This allows for using lighter carton as raw material for the box, thus diminishing the weight of the boxes and the weight of packaging materials per stem and reducing the shipping cost while lowering the carbon foot print of the package and its content.
