DK 153115BDK 153115B

Opfindelsen angår en tyndvægget plantedyrkningsbeholder af den i krav l's indledning angivne art.The invention relates to a thin-walled plant cultivation container of the kind specified in the preamble of claim 1.

En plantedyrkningsbeholder af denne art kendes fra 5 GB-patentskrift nr. 1.301.259, og den således kendte beholder fremstilles ved til at begynde med særskilt at fremstille den poselignende beholderdel af tyndvægget materiale og det rundtgående afstivnings- og bæreorgan, hvorefter disse dele sammenføjes ved en passende proces.A plant cultivation container of this kind is known from 5 GB patent specification No. 1,301,259, and the container thus known is manufactured by initially producing separately the bag-like container part of thin-walled material and the circumferential stiffening and supporting means, after which these parts are joined together by an appropriate process.

10 Det vil være indlysende, at en sådan forholdsvis kompliceret produktionsproces er uhensigtsmæssig ved fremstilling af masseprodukter af den her omhandlede art, hvor det er nødvendigt at holde omkostningerne så lave som muligt.10 It will be obvious that such a relatively complicated production process is inappropriate in the manufacture of mass products of the kind in question, where it is necessary to keep costs as low as possible.

15 Plantedyrkningsbeholderen ifølge opfindelsen er ejendommelig ved den i krav l's kendetegnende del angivne udformning. Herved opnås, at beholderen kan massefremstilles i et enkelt og for hver beholder særdeles kortvarigt arbejdsforløb, nemlig dybtrækning ud fra passende emne-20 materiale. Til trods for sidevæggens og bundens store eftergivenhed kan plantedyrkningsbeholderen ifølge opfindelsen ved passende formgivningsforanstaltninger afstives tilstrækkeligt til at gøre det muligt, dels at stable sådanne beholdere oven i hinanden i høje stabler, 25 dels uden problemer at anvende dem i maskinelle fylde- og beplantningsanlæg.The plant cultivation container according to the invention is characterized by the design according to the characterizing part of claim 1. Hereby it is achieved that the container can be mass-produced in a single and for each container very short-term work, namely deep drawing from suitable workpiece material. In spite of the great completeness of the sidewall and the bottom, the plant cultivation container according to the invention can be stiffened sufficiently by suitable shaping measures to enable, on the one hand, to stack such containers on top of each other in high stacks, and partly to use them in mechanical filling and planting plants.

Ved den i krav 2 omhandlede udførelsesform opnås, at den afstivning, der er nødvendig til at opretholde den tomme beholders form, på grund af beholdervæggens bøjelighed og 30 sejhed kan ophæves ved fyldning af beholderen med jord, så at det nu er den indfyldte jord og plantens jordklump, der sørger for beholderens stabilitet, idet planten ved rodklumpens vækst efterhånden retter de tidligere dannede ud- eller indbugtninger ud. Takket være beholdervæggensIn the embodiment according to claim 2, it is achieved that the stiffening necessary to maintain the shape of the empty container, due to the flexibility and toughness of the container wall, can be lifted by filling the container with soil so that it is now the filled soil and the soil lump of the plant which provides the stability of the container, as the plant gradually grows out the previously formed bulges or indentations as the root lump grows. Thanks to the container wall

DK153115BDK153115B

2 og beholderbundens sejhed er der under dette forløb ingen risiko for, at væggen eller bunden revner eller beskadiges på anden måde.2 and the toughness of the container bottom, during this process there is no risk that the wall or bottom will crack or otherwise be damaged.

5 Ved den i krav 3 omhandlede udførelsesform opnås en god afstivning af sidevæggen, som ikke forårsager problemer ved dybtrækningen.In the embodiment according to claim 3, a good stiffening of the sidewall is obtained which does not cause problems in the deep drawing.

Ved den i krav 4 omhandlede udførelsesform opnås, at eventuelle spændingskoncentrationer i området mellem 10 sidevæggen og bunden formindskes, hvorved risikoen for revnedannelser i dette område nedsættes.In the embodiment according to claim 4, it is achieved that any stress concentrations in the region between the sidewall and the bottom are reduced, thereby reducing the risk of cracking in this area.

Ved den i krav 5 omhandlede udførelsesform opnås en god afstivning af bunden, som heller ikke volder problemer ved dybtrækningen, og som yderligere gør det muligt i bunden 15 at udforme vandingshuller, som ikke lukkes, når beholderen stilles på et plant underlag.In the embodiment according to claim 5, a good stiffening of the bottom is obtained, which also does not cause problems in the deep drawing, and which further enables the bottom 15 to form irrigation holes which do not close when the container is placed on a flat surface.

Ved den i krav 6 omhandlede udførelsesform opnås, at de stablede beholdere holdes i en vis, ganske vist meget lille, indbyrdes afstand, hvorved det forhindres, at de 20 klæber sammen i stabelen. Herved er en sådan stabel velegnet til anvendelse i sædvanlige pottemaskiner.In the embodiment according to claim 6, it is achieved that the stacked containers are kept at a certain, albeit very small, spacing between them, thereby preventing them from sticking together in the stack. Hereby, such a stack is suitable for use in conventional potting machines.

En eventuel tilbøjelighed til klæbning mellem de enkelte beholdere kan også være af elektrostatisk karakter, hvorfor beholderen hensigtsmæssigt tillige udviser det i 25 krav 7 angivne træk.Any tendency for adhesion between the individual containers may also be electrostatic, so the container also conveniently exhibits the feature of claim 7.

Opfindelsen vil blive forklaret nærmere i det følgende under henvisning til tegningen, på hvilken fig. 1 viser en urtepotte ifølge opfindelsen, dels i aksialsnit (venstre halvdel), og dels i side-30 billede (højre halvdel), og fig. 2 viser samme, set fra oven.The invention will be explained in more detail below with reference to the drawing, in which 1 shows a herbal pot according to the invention, partly in axial section (left half) and partly in side-view (right half), and fig. 2 shows the same, seen from above.

Urtepotten 10 har en i ét stykke fremstillet pottevæg 11, der omfatter en øvre rand 12, en sidevæg 13 og en bund 14. Pottevæggen 11 er fremstillet af termoplastisk materiale 5 ved dybtrækning. Herved er den øvre rand 12 formfast udformet som et bærende og afstivende element, medens sidevæggen 13 og bunden 14 er dybtrukket i form af en folie med en tykkelse på fra 10 til 25 μια som minimum.The herb pot 10 has a one-piece pot wall 11 comprising an upper edge 12, a side wall 13 and a bottom 14. The pot wall 11 is made of thermoplastic material 5 by deep drawing. Hereby, the upper rim 12 is rigidly shaped as a supporting and stiffening element, while the sidewall 13 and the bottom 14 are deeply drawn in the form of a film having a thickness of from 10 to 25 μια as a minimum.

Den øvre rand 12 har en formfast stable- og håndgrebsrand 10 21, der indsnævres svagt konisk hen mod pottens munding, således at den ved stabling af potterne 10 med sin underkant lægger sig an mod overkanten af den nedenunder liggende potte. Højden af stable- og håndgrebsranden 21 er således lig med stableafstanden mellem de stablede potter 15 10.The upper edge 12 has a form-stable stacking and grip edge 10 21 which narrows slightly tapered towards the mouth of the pot, so that when stacking the pots 10 with its bottom edge, it abuts against the upper edge of the pot below. Thus, the height of the stacking and handle edge 21 is equal to the stacking distance between the stacked pots 10.

Foroven går stable- og håndgrebsranden 21 over i en ligeledes stabil og afstivende randflange 22, der udvendigt er krænget nedad i form af en ombertlet kant 23. I den nederste del af stable- og håndgrebsranden 21 findes en 20 overgangskant 24, der samtidig danner et nedre stable-anslag, især ved hjørnerne, fordi der dér ved overgangen fra den øvre rand 12 til sidevæggen 13 dannes anslagsplader 25, der har form af cirkel segment er. Den på tegningen viste urtepotte har i det væsentlige kvadratisk 25 tværsnit, og hjørneområderne af sidevæggen 13's tværsnit har skrå, plane overgangsflader 32, medens den øvre rand 12 har afrundede hjørnedele 26.At the top, the stack and handle rim 21 enters a likewise stable and stiffening edge flange 22 which is externally sloped downwards in the form of a fluted edge 23. In the lower part of the stack and handle rim 21 there is a transition edge 24, which simultaneously forms a lower stacking stops, especially at the corners, because at the transition from the upper edge 12 to the side wall 13, abutment plates 25, which are in the form of a circle segment, are formed. The herb pot shown in the drawing is substantially square 25 in cross section, and the corner regions of the cross-section of the sidewall 13 have oblique, flat transition surfaces 32, while the upper edge 12 has rounded corner portions 26.

Som vist i den venstre del af fig. 1 går tykkelsen af pottevæggen 11 lidt under overgangskanten 24 over fra den 30 store godstykkelse af randen 12 til den lille godstykkelse af den folieagtige sidevæg 13.As shown in the left part of FIG. 1, the thickness of the pot wall 11 extends slightly below the transition edge 24 from the 30 large thickness of the rim 12 to the small thickness of the foil sidewall 13.

Mellem de skrå overgangsflader 32 af sidevæggen 13 findes der i hver side af potten en egentlig vægdel 31, der i den 4Between the inclined transition surfaces 32 of the side wall 13 there is in each side of the pot an actual wall part 31 which in the 4

DK 153115 BDK 153115 B

viste udførelsesform er afstivet af indformede, i det væsentlige aksialt forløbende ribber 33. Med "indformede" menes her, at ribberne 33 er i ét stykke med vægdelen 31 5 og har i alt væsentligt samme tykkelse. De er dannet i samme arbejdsoperation som urtepotten i øvrigt, dvs. ved dybtrækning. Forneden er sidevæggen 13 udformet med en rundtgående skrå del 34, der går over i bunden 14. Bunden 14 har i den viste udførelsesform to i midten af bunden 10 inden for en her udformet roset 42 hinanden krydsende afstivningsribber 41, der ligesom rosetten 42 rager opad fra de fire bundsektorer 43. De skråt forløbende forbindelsesdele 44 mellem bundsektorerne 43 og henholdsvis afstivningsribberne 41 og rosetten 42 er udformet med de 15 for urtepotten nødvendige vandings- og afvandingshuller 45.The embodiment shown is stiffened by formed, substantially axially extending ribs 33. By "formed" is meant here that the ribs 33 are integral with the wall portion 315 and have substantially the same thickness. They are formed in the same working operation as the herbal pot in general, ie. by deep drawing. Below, the side wall 13 is formed with a circumferential inclined portion 34 extending to the bottom 14. In the illustrated embodiment, the bottom 14 has two intersecting stiffening ribs 41 intersected here, which like the rosette 42 protrude upwards, like a rosette 42. from the four bottom sectors 43. The inclined connecting portions 44 between the bottom sectors 43 and the stiffening ribs 41 and the rosette 42, respectively, are formed with the watering and drainage holes 45 required for the herbal pot.

For at forhindre, at pottevæggen 11 oplades elektrostatisk er der i den viste udførelsesform på indersiden af pottevæggen 11 anbragt et lag 15, der består af samme eller 20 lignende materiale som pottevæggen 11, hvortil imidlertid er sat en kemisk forbindelse, der forhindrer en elektrostatisk opladning af kunststofoverfladen.To prevent the pot wall 11 from being electrostatically charged, in the illustrated embodiment, on the inside of the pot wall 11, a layer 15 consisting of the same or similar material to the pot wall 11 is provided, to which, however, is added a chemical compound which prevents an electrostatic charge. of the plastic surface.

Urtepotten 10 er fortrinsvis fremstillet af en polyolefin, f.eks. polypropylen. Imidlertid kan hvilke som helst andre 25 termoplastiske stoffer komme i betragtning. Polyolefiner, især polypropylen, giver imidlertid den fordel, at den folieagtigt tynde sidevæg 13 og bunden 14 bliver særlig fleksible og seje.The herb pot 10 is preferably made of a polyolefin, e.g. polypropylene. However, any other thermoplastic substances may be considered. However, polyolefins, especially polypropylene, have the advantage of making the foil-thin side wall 13 and the bottom 14 particularly flexible and tough.

Hvis potterne ikke skal stables eller stilles op enkelt-30 vis, er der også inden for rammerne af opfindelsen mulighed for at udforme sidevæggen 13 og bunden 14 mere pose-agtigt, dvs. uden afstivningselementer. Under lagring og transport kan derved sidevæggen 13 og bunden 14 være sammenfoldet neden under den stive øvre rand 12.If the pots are not to be stacked or set up individually, it is also possible within the scope of the invention to design the side wall 13 and the bottom 14 more bag-like, ie. without stiffening elements. During storage and transport, the side wall 13 and the bottom 14 can thereby be collapsed below the rigid upper edge 12.
