Abstract
Description
- The present invention belongs to the field of products made of paper, more precisely to the field of packaging for flowers and plants. The invention also belongs to the field of manufacturing processes, especially to the field of devices for cutting, shaping and gluing paper with the aim of manufacturing paper packaging.
- 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 whom 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 the design of a simple paper packaging into which a plant in a pot can be insterted and consequently protected against environmental conditions, while the packaging itself may also function as 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.

KR20170057475 - Utility design
CN203623034 disloses equipment for manufacturing paper for wrapping fresh flowers. The equipment comprises an expansion device, a frame and shape cutter below the paper, whereas the frame is located above the paper. Obtained products have the shape of an upside-down turned umbrella, while its bottom part is in the shape of a cup. The equipment enables reliable and fast manufacturing of packaging for fresh cut flowers. - Patent application
KR101471812 - 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 known documents in that it ensures simple single-piece packaging produced with less steps and less complex equipment.
- The essence of the paper packaging according to the invention is in that it is designed as a right-angled trapezoid having two base sides with different lengths, wherein the base sides are perpendicular to one of both legs. The packaging with said shape is made from an unfolded paper basis, which is folded so that the bottom side is wider and consequently has a narrow edge intended for gluing onto the other side of the trapezoid. The upper part of the so folded basis is cut into a triangular shape. Then the upper part of the narrow band, which is folded after gluing, is cut; wherein the cut part is triangularly shaped. 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 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 and cut into a right-angled trapezoid. In case the shape is unfolded, the basis has a shape of an equilateral trapezoid (isosceles). 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.
- The manufacturing method of the said paper packaging thus includes the following steps:

figure 6a the paper packaging for plants 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.
