Description
- The present invention belongs to the field of products made of paper, more precisely to the field of flower and plant packaging. The invention relates to a paper packaging for plants.
- Floriculture has from its beginnings in the 19th century developed into a dynamic, global and fast growing industry. It includes growers, distributers and sellers, which whome the buyers are mostly in contact. When a plant or flowers are purchased, they often have to be wrapped, either to protect the plants from environmental conditions, either to make them look as a gift. As florists sell a wide variety of plants, namely individual cut flowers, boquets, potted plants and plants without pots, packaging has to be adjusted accordingly. Typically, a larger sheet of paper is used in order to wrap any kind of purchased plants. Such solutions are described in documents
US5666784 andUS2008264552 . DocumentUS2005082353 for example discloses pre-prepared sheets for packing flower boquets, wherein the sheet is folded and glued in a particular way. This solution is useful for wrapping cut flowers and boquets, while it is less appropriate for potted plants. Recently different versions of packaging have been developed, mostly in the shape of bags or sheats of varous sizes with regards to potted plants and cut flowers. The problem of these types of packaging is in their manufacture, as they are made from several parts of paper or the material is non-economically used, thereby creating lots of waste. - The technical problem, which is solved by the present invention, is thus design of a simple paper packaging into which a plant in a pot can be insterted and protected against environmental conditions, while the packaging itself will also function as a decoration. The aim of the invention is also the design of a suitable device for manufacturing said packaging, as known solutions differ significantly in their design. The invention has to be suitable for different sizes of potted plants and for different types of paper.

US 2002/0069614 A1 discloses a package according to the preamble ofclaim 1. - All described solutions are despite their usefulness very complex, which increases the costs of the packaging. As flower industry is widespread and lots of packaging is needed, its price has to be reduced as much as possible. The present invention differs from the state of the art documents in that it ensures simple single-piece packaging produced with less steps and less complex equipment.
- The technical problem is solved by a packaging according to
claim 1, wherein dependent claims define preferred embodiments of the invention. - The paper packaging according to the invention is designed in the shape of a truncated cone arranged to receive a plant with or without a pot, wherein the paper packaging is made from a basic sheet in the shape of an isosceles trapezoid with base sides of different lengths and two legs of same lengths, wherein the final packaging is obtained in the following manner:
- the basic sheet is folded along an axis crossing both base sides so as to form a right-angle trapezoid, the axis being moveable left or right so as to leave an edge, wherein the folded edge forms a short leg of the right-angle trapezoid and the outmost leg of the basic sheet forms a long leg of the right-angle trapezoid; from which
- a frist triangle is cut off along a cut line crossing the long leg and the corner formed by the longer base side and the folded edge to form a second sheet; from which a second smaller triangle is cut along a cut line crossing the long leg of the right-angle trapezoid and the corner formed by the innermost leg of the basic sheet and the longer base side to obtain a third sheet;
- the third sheet being formed by, in counter-clockwise order: the folded edge, the shorter base side comprising a double thickness portion and a single thickness portion of the width of the edge, the remaining part of the long leg of the right-angle trapezoid, the cut line of the second triangle, and the remaining part of the cut line of the first triangle; wherein the edge is then provided with glue, folded over the innermost leg of the basic sheet onto the opposite side to be glued onto it so as to form the final packaging.
- After that the packaging approximately shaped as a truncated cone is obtained, into which a plant with or without a pot can be inserted. Dimensions of individual base sides and legs are arbitrary and can be in different combinations, so that various sizes of packaging is obtained in order to pack plants or potted plants of different sizes. The paper material used for the said packaging may be any suitable for floral industry, wherein paper from pure cellulose resistant to moisture is particularly useful. The unfolded base of the packaging is prepared by cutting a larger sheet of material, preferably with a device that enables cutting under different angles. The cut shape is then folded along the middle into a right-angled trapezoid. In case the shape is unfolded, the basis has a shape of an isosceles trapezoid. Glue is applied to one of the trapezoid legs and then both legs are glued to each other. Thereby a packaging is created, into which a plant or a potted plant can be inserted. Cutting into the right-angled trapezoid as well as gluing may be performed manually, but the preferred option is to use suitable devices, which allow cutting into desired shapes and automatic application of glue on appropriate surfaces.
- For illustration purposes only, the manufacturing method of the said paper packaging thus includes the following steps:
- a) Cutting several layers of paper or any other suitable material;
- b) Cutting with a bar with knife in the selected groove in the upper part of the table to obtain paper basis attached with said bar, which covers the edge of the equilateral trapezoid on the left and right side of the bar;
- c) Manual folding of the free edge of the first trapezoid and pressing with a regular ruler;
- d) Manual folding of the free edge of the second trapezoid and presing with a regular ruler;
- e) Releasing the bar to obtain two groups of trapezoid shaped sheets having the edge equal to the half of the bar;
- f) Transfer of the first group of sheets into the cutting table, where the upper part of the sheet is obliquely cut;
- g) Moving the equipment and cutting the part with a free straight edge;
- h) Transfer of the cut group of papers to the table with a gluing mechanism;
- i) Application of glue to the pre-prepared bottom straight edge of the paper sheet with trapezoid shape;
- j) Folding the sheet in a manner that covers the glue applied in step i);
- k) Opening the upper aperture of the packaging obtained after gluing, the packaging being stacked onto the previously prepared packaging;
- l) Stacking manufactured packagings one onto another by opening the upper aperture as described in step k).
- The paper packaging for plants according to the invention enables simplified packaging of potted plants, wherein the manufaturing process for obtaining the packaging is simpler and more economical (efficient) than already known processes, which are complicated and multi-step methods. Obtained packaging is used so that it is opened and a potted plant or a plant is insterted into the packaging. The dimension of the packaging depends on the diameter of the pot and on the height of the plant. In case the packaging is too high, it can be cut and thus shortened. This is particularly useful for short plants with wide pots.

figure 6a the paper packaging for plants according to the invention is designed as a basic sheet A shaped as a right-angled trapezoid with base sides a1 and a2 having different lengths and two side legs b1 and b2 having the same length. The basic sheet A is cut on the table 2 along the oblique grooves marked with D and D'. During cutting of the twelve layers of paper to sets of basic sheets are obtained, wherein one set is in the position of a large letter A, while the second set is in the position of a large letter A rotated for 180°. Common sides are on the line of the cut made by thebar 23. This creates an edge A3 with a width of approximately two centimetres. The width of the edge A3 depends on the width of the bar edge and knife in the middle of the bar. The axis Y is moved for the width of the edge A3, into the left for the left set and into the right for the right set. When thebar 23 is still fixed, the outer edge with the leg b1 is manually folded to the edge of thebar 23. The same is performed for the second set of basic sheets A, wherein both sets are pushed with a ruler along the fold line from one end to another, in order to create the fold d1. Thus prepared sets of sheets A are moved to table 3. Lengths of base sides and legs are arbitrary and based on the required dimensions of the packaging. Preferred dimensions of sides of the packaging are shown in Table 1 below.Table 1 Dimension of the basic sheet d1 in cm b2' in cm a4 in cm a5 in cm 1. A cut along D1, D1' 60 42 13 2 2.
