Description

15 20 25 30 35 7710747-2 övre del och hylsans övre del vara så utformade, att de snäpp- artat fäster i varandra, d.v.s. genom att upphöjningar eller - utsprâng i den ena delen fås att fjädrande ingripa i motsvarande fördjupningar i den andra delen. The upper part and the upper part of the sleeve are designed so that they snap-fit to each other, i.e. by making elevations or protrusions in one part resiliently engage in corresponding depressions in the other part.

Uppfinningen beskrivs i det följande under hänvisning till bi- fogade ritningar, på vilka fig. 1a och 2a från sidan visar olika utföringsformer av hylsans undre del, fig. 1b och 2b visar änd- vyer av samma hylsor och fig. 3a fästningen av kragen på hylsan.The invention is described in the following with reference to the accompanying drawings, in which Figs. 1a and 2a show from the side different embodiments of the lower part of the sleeve, Figs. 1b and 2b show end views of the same sleeves and Fig. 3a the attachment of the collar to sleeve.

Enligt fig. 1 är hylsan 1 förlängd nedåt genom band 2,3,4 och 5, vilka är formade i ett stycke med hylsan och är inbördes förenade, så att de bildar en korsformad botten, som tillsammans med de nedåtriktade delarna av banden bildar en delvis öppen behållare för plantans 6 rot-substrat-klump 7.According to Fig. 1, the sleeve 1 is extended downwards by strips 2, 3, 4 and 5, which are formed in one piece with the sleeve and are interconnected so that they form a cross-shaped bottom, which together with the downwardly directed parts of the strips form a partially open container for the root-substrate clump 7 of the plant 6.

Enligt fig. 2 har hylsan 1 förlängts nedåt med bandartade partier 12, 13, 14 och 15, som är omböjda nedtill, så att de kan gripa in i rot-substrat-klumpens vertikala vägg eller, om de görs till- räckligt långa, gripa om klumpens botten.According to Fig. 2, the sleeve 1 has been extended downwards with banded portions 12, 13, 14 and 15, which are bent at the bottom, so that they can engage in the vertical wall of the root-substrate lump or, if made sufficiently long, grip about the bottom of the lump.

I fig. 3 visas en hylsa 1', som upptill är försedd med en runt hylsans periferi gående fördjupning eller inskärning 16, som är avsedd att samverka med ett motsvarande format utsprång 17 på en till hylsan hörande lös krage 18. Såsom tidigare nämnts, är denna utformning av hylsan speciellt lämplig vid plantering med planteringsrör, genom att hylsan obehindrad kan passera genom planteringsröret och därefter kragen kan monteras på hylsan.Fig. 3 shows a sleeve 1 ', which is provided at the top with a recess or notch 16 extending around the periphery of the sleeve, which is intended to co-operate with a correspondingly shaped projection 17 on a loose collar 18 belonging to the sleeve. this design of the sleeve is particularly suitable for planting with planting tubes, in that the sleeve can pass unhindered through the planting tube and then the collar can be mounted on the sleeve.

Denna utföringsform är också speciellt lämpad för direkt plante- ring i hylsan, genom att flera hylsor utan påsittande krage tätt kan placeras intill varandra i ett växthus.This embodiment is also particularly suitable for direct planting in the sleeve, in that several sleeves without a fitted collar can be placed close together in a greenhouse.

För samtliga beskrivna utföringsformer gäller, att hylsans och/ eller den nedåtriktade förlängningens material skall vara så snabbt nedbrytbart, att det inte stör rötternas utveckling. _ Lämpligt är att materialet är tillräckligt nedbrutet efter högst tre år.For all described embodiments, the material of the sleeve and / or the downward extension must be so quickly degradable that it does not interfere with the development of the roots. It is advisable that the material is sufficiently degraded after a maximum of three years.

Claims

7710747-2 P A T E N T K R A V

1. A device for preventing or hindering creeping insects, such as beetles (Hylobius abietis), from attacking plants, such as pine and spruce plants, which device comprises a sleeve which is intended to be placed around a plant and up is provided with a downward-facing collar, which forms an acute angle with the sleeve surface of the sleeve, characterized in that the sleeve (1) is extended downwards from its lower edge with spaced bands or strips (2,3,4,5; l2 , l3, l4, l5), which are arranged to enclose and grip the plant's root ball (7) when the plant is placed in the sleeve, so that the sleeve is retained by the plant after the plant has been transplanted.

Device according to claim 1, characterized in that the ends of the strips or strips (2,3,4,5; l2, l3, l4, l5) are bent and directed inwards to grip under the root ball of the plant.

Device according to claim 2, characterized in that the bent ends of the bands or strips (2,3,4,5) are joined to form a support for the root ball of the plant.

Device according to claim 2, characterized in that the bent ends of the strips or strips (l2, l3, l4, l5) are provided with tips which can penetrate into the root ball of the plant.

Device according to one of the preceding claims, characterized in that the sleeve at the top is provided with means (16) for snap-shaped, form-fitting engagement with corresponding means (17) on a loose collar (18) belonging to the sleeve.
