    15 20 25 30 35 PG19610ENO0 SUMMARY However, there are a number of disadvantages of the prior art. The present invention aims to provide an improved device for protecting a plant, such as conifers, from insect infestation and mainly from infestation by the beetle (Hylobius abietis), or at least minimizing such infestation. More specifically, the invention relates to a device for protecting a plant from insect infestation. The device has a base portion having an opening for insertion of the plant along a line. The base portion includes a sleeve-shaped portion which extends from the base portion along the line. The sleeve-shaped portion comprises a first and a second end, the first end being arranged to the base portion and the second end being arranged away from the base portion. The base portion and the sleeve-shaped portion are adapted to at least partially enclose the plant during use to protect the plant from insect infestation. The sleeve-shaped portion has holes throughout.
    The base portion further comprises a collar which extends in substantially the same direction as the sleeve-shaped portion along the line.
    The through holes are through slots. By using slots instead of holes, e.g. a snow beetle is tricked into staying close to the slot, as it has a high sense of the plant. Furthermore, the beetle will go to a position against the base portion of the device where it will be prevented by the collar from continuing to advance.
    According to one aspect of the invention, the through slots have a width / length ratio of less than 1/5, preferably less than 1/10. This gives a good length of the slits, which gives a high air passage so that the insects can perceive the plant, e.g. by scent.
    According to one aspect of the invention, the through slots have a width and that the width is greatest in connection with the first end of the sleeve-shaped portion. This means that the insect will sense the scent of the plant with the greatest strength at the widest part of the slits. However, the slits are not wide enough for the insect, and mainly a beetle beetle, to be able to climb through the slit.
    According to one aspect of the invention, the through slots are provided adjacent the first end of the sleeve-shaped portion. The second end of the sleeve-shaped portion may also have continuous slots, which may be the same as the continuous slots at the first end, or independent and separated slots thereof. A combination of these different types is of course also possible. Because the slits are arranged in direct connection with the first part of the newly joined portion, i.e. at the part which is directly adjacent to the base part, the insects will climb to the part where the distance between the collar and the sleeve-connected part is the least, which makes it black for them to climb further.
    According to one aspect of the invention, the sleeve-shaped portion has at least 10 continuous slots. The at least 10 continuous slots are preferably adjacent the first end of the nylon-shaped array.
    According to one aspect of the invention, the sleeve-shaped portion is formed by a plurality of longitudinal arms separated by a space, the continuous slots being defined by the space between the longitudinal arms. This is a simple device to manufacture, mainly with injection molding.
    The longitudinal arms can also advantageously be made cleformerlaara, ie. flexible, so that they can be dieforined upon insertion of a plant through the opening on the base portion. This means that the device can easily be held at a given position on the plant.
    According to one aspect of the invention, the longitudinal arms and the through slots extend substantially parallel to the above-mentioned line.
    According to one aspect of the invention, the first end of the sleeve-shaped recess has an opening with a first diameter and the second end of the sleeve-shaped portion has an opening with a second diameter, the first diameter being larger than the second diameter. The sleeve-shaped portion may be substantially conical or have the front of a truncated cone.
    According to one aspect of the invention, the collar comprises a plurality of longitudinal arms separated by slits. Alternatively, the collar can consist of a homogeneous wall, ie. no through heels.
    According to one aspect of the invention, a compliant material, such as fabric, film or nonwoven material, is provided to the collar to prevent the insect from accessing the plant. PG1961OSEOO 4 According to one aspect of the invention, a compliant material, such as fabric or nonwoven material, is provided to the sleeve-shaped portion to prevent the insect from accessing the plant. The compliant material may be in the form of a cylinder, or sock, to be able to cover the plant.
    According to one aspect of the invention, the compliant material has a first and a second end, and that an opening adapted to the second end of the compliant material is provided to allow the root system of the plant to grow out of the opening.
    According to one aspect of the invention, the compliant material is made of a compliant nonwoven material, such as polypropylene, polyethylene, biodegradable nonwoven, e.g. based on starch or lactic acid (PLA), or mixtures thereof, alternatively films of similar or the same material may be used.
    According to one aspect of the invention, the compliant material is breathable, such as a breathable film or a breathable nonwoven.
    According to one aspect of the invention, the compliant material is made of a transparent material, partially transparent material or a non-transparent material.
    According to one aspect of the invention, the compliant material is a laminate, such as a nonwoven laminate, film laminate or a nonwoven / film laminate.
    According to one aspect of the invention, the base portion is substantially annular. Other shapes can also occur such as polygonal shapes such as triangular, square, pentagonal or the like.
    According to one aspect of the invention, the base portion and the sleeve-shaped portion are made of separate parts, alternatively, the collar, the base portion and the sleeve-shaped portion may be made of separate parts.

    DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Figures 1a-1b show in perspective view a first embodiment of the present invention. Figures 1a-1b show a device 10 for protecting a plant from insect infestation, mainly beetles, with a longitudinal center line L. The device 10 has a base portion 11, in the form of an annular base 11, which defines an opening 12 from which a sleeve-shaped lot 13 extends. The sleeve-shaped portion 13 is arranged to be at least partially abutting the plant during use, or to be in close proximity to the plant during use. A collar 40 extends in the same direction as the sleeve-shaped portion 13 and is arranged to provide a physical obstacle for the insect, which will be described in greater detail below.
    The sleeve-shaped portion 13 has a first opening 14, which is synonymous with the opening 12 on the annular base 11, and a second opening 15. In use, a plant is intended to be inserted through the first opening 14 and out through the second opening 15 on the sleeve-shaped portion 13. The sleeve-shaped portion 13 has, in the embodiment shown, the shape of a truncated cone (frustrum) but can also be substantially cone-shaped. In the embodiment shown, the sleeve-shaped portion 13 is formed by a plurality of arms 20 which extend in the direction of the longitudinal center line L, however, slightly angled thereto. Holes in the form of slits 21 are arranged between the arms 20. The arms 20 can advantageously be arranged to flex, i.e. deformed, under load, ex. during insertion of a plant, so that the distance between the arms 20 changes, i.e. the size of the slots 21 can be changed. After a plant has been inserted through the first opening 14 on the sleeve-shaped portion 13, the arms 20 can abut against the plant to hold the device 10 in place. PG19610SEO0 6 The sleeve-shaped portion 13 has a first proximal end 16 and a second dlstal end 17, with respect to the annular base 11. The proximal end 16 is the end of the sleeve-shaped portion 13 arranged to the the annular base 11 and the distal end 17 is the end arranged away from the annular base 11. The annular base 11, and also the proximal end 16 of the sleeve-shaped portion 13, has a first diameter D1. The distal end 17 of the sleeve-shaped portion 13 has a second diameter D2. In the embodiment shown in Figure 1, the first diameter D1 is larger than the second diameter D1. In one embodiment, the ratio D1 / D2 is greater than 1.2, preferably 1.2-8.
    Figure 2 shows a side view of the device 10 from Figures 1a-1b, the sleeve-shaped portion 13 with the first proximal end 16 and the second distal end 17. The first and second diameters D1, D2 are also shown.
    The arms 20 protect the plant after the device 10 has been applied to the plant. An insect, for example a snow beetle, can smell the plant through the slits 21, but does not penetrate between the arms 20 to access the plant. In order for the device 10 to be particularly suitable for protection against snow beetles, the slits must have a width of about 1-4 mm. The width of the slits here means the same thing as the distance between the arms 20.
    The device 10 for protecting a plant against insect infestation also has a collar 40.
    The collar 40 is adapted to prevent the invading insects from reaching the plant by providing a barrier function. The collar 40 may, as in the embodiment shown in Figures 1a-2, comprise a number of longitudinal arms 41. The arms 41 extend in substantially the same direction as the sleeve-shaped portion 13, but parallel to the longitudinal center line L. As shown in Figure 2, through angled arms 20 of the sleeve-shaped portion 13, the distance A between the collar and the arms 20 of the sleeve-shaped portion 13 increases.
    The distance A is greatest where the collar 40, and the arms 41, end, and is preferably larger than 10 mm, preferably larger than 15 mm. The distance A can be between 10-50 mm, preferably 10-30 mm. At the proximal end 14 of the sleeve-shaped portion 13, the distance to the collar 40 is defined by the width B of the annular base 11.
    As shown in Figures 3a-3b, the collar 40 can be used to attach a material, such as a compliant nonwoven fabric 50, which provides additional barrier function to the collar 40. The distance between the arms 41 on the collar 40 can be advantage be such that a snow beetle can not get between, ie. 1-4 mm. In such cases, the compliant nonwoven fabric 50 need not be attached along the entire length of the arms 41.
    The compliant nonwoven material 50 may also extend past the collar 40, as shown in Figure 3a, in the direction away from the sleeve-shaped portion 13, to be used to seal around the plant and thereby prevent access of a larger part of the plant.
    The collar 40 need not be constituted by several arms, such as the arms 41 shown, but may be formed of a continuous material, without slits or holes extending around the periphery of the annular base 11, i.e. the base part.
    Figures 3a show the device 10, parts of the sleeve-shaped portion 13, and a first flexible nonwoven material 50, and a second flexible nonwoven material 51. The first flexible nonwoven material 50 is attached to the collar 40 and has substantially the shape of a cylinder, or sock, which can connect around a plant 54, as shown in Figure 3b, with, for example, an elastic bandage 53. Alternatively, the compliant nonwoven material 50 may be glued together. By sealing, or partially sealing, the first compliant nonwoven material 50 around the plant 54, access to a larger portion of the plant is prevented.
    The second compliant nonwoven material 51 is attached to the distal end 17 of the sleeve-shaped portion 13 with, for example, glue or other fastener. The second compliant nonwoven material 51 is in the form of a cylinder, or sock, having a first and a second end 56, 57, the first end 56 of the second compliant nonwoven material 51 being disposed to the distal end 17 of the sleeve-shaped portion 13. The lark plane 60 is shown in Figure 3b, which is noted that the root system 55 of the plant has been lowered into the soil for planting.
    As noted in Figure 3b, the second compliant nonwoven material 51 has an opening 58 at the other end 57 of the second compliant nonwoven material 51 so that the root system 55 of the plant 54 can grow without being obstructed by the second compliant nonwoven material 51 after planting.
    The first and second compliant nonwovens 50, 51 may be made of polypropylene, polyethylene, or biodegradable materials. Examples of biodegradable nonwoven materials may be starch-based nonwovens, such as those described in U.S. Patent 6,890,872, Procter & Gamble. Nonwovens based on fibers of homopolymers or copolymers of lactic acid (PLA) can also be used, examples of such a material are described in the publication WO 0134886 A1, Kimberly-Clark CO.
    In the embodiments shown, the device 10 is described in connection with a compliant nonwoven material. It should be noted that the invention can also be used with a protective cloth or protective material in the form of films, e.g. plastic films, or fabric material, ie. woven materials. Even rigid materials may be suitable in some contexts. Rigid plastic materials can be used, for example, even if rigid biodegradable materials are preferred. According to one aspect of the invention, the compliant material is breathable, such as a breathable film, a breathable nonwoven or laminate thereof.
    The breathability can be 200 g / m2 / 24h, 300 g / m2 / 24h, alternatively 1000g / m2 / 24h.
    Examples of breathable materials are described in patent publication US 6420625, Kimberley Clark CO.
    The use of the device 10, as well as the compliant nonwoven material 50, 51 attached to the device 10 will be described below in more detail. Figure 4 shows an embodiment of the device 10 for protecting a plant 54 against insect infestation, similar to the device 10 which is shown in Figures 1a-3, but with a collar 40 without arms. Instead, the collar 40 is constituted by a continuous wall which extends around the annular base 11 in the same manner as the collar 40 shown in Figures 1a-3b.
    A plant 54 has been inserted through the first opening 14 and out through the second opening 15 on the sleeve-shaped portion 13 and then planted in soil, as shown in Figure 3b. After planting, the plant can be attacked by insects. The device 10 is primarily intended to counteract attacks on coniferous plants, e.g. spruce plants, of beetles (Hylobius abietis) which usually have the size 8-14 mm ivux state. After the plant 54 has been planted, the snow beetles can climb along the second compliant nonwoven material 51. A first obstacle, or resistance, they encounter is that the second compliant nonwoven material is made in a light color, preferably a white color. The beetle in tests has shown a reluctance to move over light fields, probably due to by exposing a clear contrast of their bodies to potential hunters. However, as shown in Figure 10, snout beetles will still climb up towards the device 10 and its through-going slots 21 defined by the arms 20 of the sleeve-shaped portion 13.
    As noted in Figure 5, but also in Figures 1a-1b, the distance between the arms 20, i.e. the width of the slits 21, larger closest to the annular base part 11. In accordance with an aspect of the invention, the width of the slits thus increases the closer one gets to the annular base part. In the embodiments shown, the slots 21 have a first and a second transverse end, a first and a second longitudinal side. The first transverse end is smaller than the second transverse end.
    In general it can be said that the longitudinal slits 21 give the beetles a sense of the plant 54 and that they therefore become reluctant to leave the place of the continuous slits 21. The beetles tend to climb upwards, however they are met by the collar 40, which effectively blocks the path for them. In those cases where, as in the embodiment shown in Figures 1a-5, with slots 21 which change width, i.e. becomes wider adjacent to the annular base 11, the beetles become even more likely to climb upwards. As shown in Figure 5, the beetles climb as far up as they can, but are then reluctant to climb further when they reach a position on the sleeve-shaped portion 13 where the sensation, or smell, from the plant 54 is greatest. In addition, in the embodiment shown, they are physically prevented from being able to climb around the collar in that the distance between the collar 40 and the sleeve-shaped portion 13 is small, i.e. <10 mm, preferably only 3-7 mm.
    The described device 10 is preferably manufactured by injection molding a plastic material such as polyethylene, polypropylene or the like. However, biodegradable materials are preferred, such as starch-based material or cellulose-based material.
