Description
Oppfinnelsen vedrører en beholder, og mer spesielt en engangsbeholder. The invention relates to a container, and more particularly a disposable container.
Det er et behov for billige beholdere, og spesielt beholdere som er delvis permeable for å utgjøre innsatser for å tilveiebringe kontrollerbar filtrering eller separasjon, og for bruk som filtre., i industrielle prosesser? luftrenseanord-ninger, såsom luftfiltre^for motorkjøretøyer, i perkolerings-eller siktesystemer og andre typer separeringsutstyr. Det er også et behov for beholdere for bruk som blomsterpotter eller plantepotter. There is a need for inexpensive containers, and particularly containers which are partially permeable to constitute inserts to provide controllable filtration or separation, and for use as filters., in industrial processes? air cleaning devices, such as air filters for motor vehicles, in percolation or screening systems and other types of separation equipment. There is also a need for containers for use as flower pots or plant pots.
I henhold til foreliggende oppfinnelse er det til-veiebragt en fremgangsmåte for fremstilling av en beholder som omfatter støping av en bane av plastmateriale i et formings-verktøy ved en formingsstasjon, slik at banen danner en beholder med en væsketett sidevegg, og at den formede beholder ad-skilles fra resten av banen ved hjelp av samvirkende elementer som er bevegelige i forhold til hverandre, hvorved i forbindelse med eller etter formetrinnet beholderen utstyres med en permeabel eller semipermeabel basisdel. According to the present invention, a method for the production of a container is provided which comprises casting a web of plastic material in a forming tool at a forming station, so that the web forms a container with a liquid-tight side wall, and that the formed container separated from the rest of the web by means of cooperating elements which are movable in relation to each other, whereby in connection with or after the shaping step the container is equipped with a permeable or semi-permeable base part.
Nevnte beholdere kan være formet av en oppvarmet bane av termoplastisk materiale som fremføres trinnvis til formingsstasjonen, og fortrinnsvis bringes ett eller flere formingsverktøy til en driftsstilling ved formingsstasjonen, slik at en beholder kan støpes i denne, og samtidig blir form-ings- eller støpingsverktøyet som tidligeré befant seg ved formingsstasjonen beveget til en utleveringsstasjon, slik at beholderne som er støpt kan fjernes. Hensiktsmessig kan form-ingsverktøyét omfatte en avtrapning i et verktøy, idet det er anordnet innretninger for evakuering av avtrapningen, slik at materialbanen blir vakuumformet. Fordelaktig blir beholderen adskilt fra banen ved hjelp av et kutteblad som samvirker med en ettergivende anslagsflate i formingsverktøyet/ og fortrinnsvis er kuttebladet oppvarmet. Said containers can be formed from a heated web of thermoplastic material which is advanced step by step to the forming station, and preferably one or more forming tools are brought to an operating position at the forming station, so that a container can be molded therein, and at the same time the forming or molding tool which previously located at the forming station moved to a dispensing station, so that the containers that have been cast can be removed. Appropriately, the forming tool can include a taper in a tool, as devices are arranged for evacuating the taper, so that the material web is vacuum formed. Advantageously, the container is separated from the web by means of a cutting blade which interacts with a yielding abutment surface in the forming tool/ and preferably the cutting blade is heated.
Ved en utførelsesform av fremgangsmåten formes en beholder med en indre basis, idet perforeringer^utformes i basisen til beholderen. Trinnet med perforering av basisen kan gjennomføres i formingsverktøyet og kan utføres ved hjelp av oppvarmede stifter som samvirker med en ettergivende anslagsflate som danner en del av formingsverktøyet. Fortrinnsvis gjennomføres perforeringstrinnet samtidig med avdelingstrinnet for den formede beholder fra resten av banen. Alternativt kan perforeringstrinnet gjennomføres med ultralyd mot en stiv støtteflate. In one embodiment of the method, a container is formed with an inner base, perforations being formed in the base of the container. The step of perforating the base can be carried out in the forming tool and can be carried out by means of heated pins which interact with a yielding abutment surface which forms part of the forming tool. Preferably, the perforation step is carried out simultaneously with the separation step of the shaped container from the rest of the web. Alternatively, the perforation step can be carried out using ultrasound against a rigid support surface.
Ved en annen utførelse..;av fremgangsmåten blir basisen til beholderen stanset ut helt eller delvis i formings-verktøyet, og utstansingen kan gjennomføres samtidig med avdelingen av beholderen fra resten av banen. Fortrinnsvis blir basisen av beholderen stanset ut med en kuttekant som samvirker med en ettergivende anslagsflate i formingsverktøyet. In another embodiment of the method, the base of the container is punched out in whole or in part in the forming tool, and the punching can be carried out simultaneously with the separation of the container from the rest of the web. Preferably, the base of the container is punched out with a cutting edge which cooperates with a yielding abutment surface in the forming tool.
Basisien til avtrapningen i formingsverktøyet i hvilken beholderen tilformes kan være utstyrt med en åpning, The base of the taper in the forming tool in which the container is formed may be provided with an opening,
og innretninger kan være anordnet for forbindelse av åpningen med en undertrykkskilde eller partiell undertrykkskilde, slik at etter utstansingen av basisen av beholderen kan den utskårede basis bli fjernet fra formingsverktøyet ved hjelp av undertrykk eller partielt undertrykk. Fortrinnsvis er det anordnet en kontrollventil mellom åpningen og undertrykkskilden eller den partielle undertrykkskilde. Mens perforeringene eller åpningene som er tilformet i basisen av beholderen gjør den permeabel, er det foretrukket at perforeringene eller åpningene som tilformes i basisen av beholderen er dekket av et gass- eller væskepermeabelt element, såsom et f iltereLément., som omfatter filtreringspapir som kan festes til beholderen ved termosveising eller ved annen fastliming. * and means may be provided for connecting the opening with a source of negative pressure or partial negative pressure, so that after punching out the base of the container, the cut-out base may be removed from the forming tool by means of negative pressure or partial negative pressure. Preferably, a control valve is arranged between the opening and the negative pressure source or the partial negative pressure source. While the perforations or openings formed in the base of the container make it permeable, it is preferred that the perforations or openings formed in the base of the container are covered by a gas or liquid permeable element, such as a filter element, which comprises filter paper that can be attached to the container by thermo-welding or by other gluing. *
Fortrinnsvis innbefatter fremgangsmåten trinn medPreferably, the method includes steps of
å tilveiebringe en beholder med en rundt omkretsen forløpende utoverrettet utbukting, som er plassert i en avstand fra toppen av beholderen for å lette stablingen. Fremgangsmåten kan inn-befatte det trinn at det tilveiebringes en beholder med stive, i det vesentlige horisontale utoverragende fremspring, idet den resulterende beholder er egnet for bruk som en tesil, kaffetrakter eller lignende. Beholderen kan være utstyrt med avstivende eller forsterkende elementer som utstrekker seg langs basisen av beholderen og er fortrinnsvis utstyrt med en providing a container with a circumferentially outwardly directed bulge spaced from the top of the container to facilitate stacking. The method may include the step of providing a container with rigid, essentially horizontal protruding projections, the resulting container being suitable for use as a tea strainer, coffee maker or the like. The container may be equipped with stiffening or reinforcing elements that extend along the base of the container and is preferably equipped with a
radielt utover i omkretsretning forløpende flens ved toppdelen. radially outwards in the circumferential direction continuous flange at the top part.
Oppfinnelsen vedrører også en beholder fremstilt ved ovenfor nevnte fremgangsmåte. The invention also relates to a container produced by the above-mentioned method.
Oppfinnelsen skal i det følgende nærmere forklares ved hjelp av utførelseseksempler som er fremstilt på tegningene, som viser: ° In the following, the invention will be explained in more detail with the help of design examples which are shown in the drawings, which show: °

Fig. 1 og 2 viser en beholder som har en permeabel basis og som er blitt fremstilt i samsvar med oppfinnelsen. Beholderen 1 er sirkulær i form og har en sidevegg la som a<y->smalner konisk fra en øvre radiell utoverrettet krave eller flens 2 mot en bunn med radielt innover forløpende krave eller flens 3. Veggen la er fremstilt av et termoplastisk materiale og er homogen og ikke permeabel. Således er veggen gass- og væsketett. Den innoverrettede krave eller flens 3 bestemmer en sirkulær åpning 4 i midten av basisen til beholderen 1. En sirkulær skive av gass-, eller væskepermeabelt materiale, såsom en skive av porøst papir eller lignende, hvor skiven har en større diameter enn diameteren til åpningen 4 er festet til flensen 3 ved hjelp av et adhesiv eller ved.varmforsegling rundt omkretskanten 6 til flensen 3, slik at åpningen 4 lukkes. Skiven 5 tjener i denne beholder som et filterelement. Fig. 1 and 2 show a container which has a permeable base and which has been produced in accordance with the invention. The container 1 is circular in shape and has a side wall la which tapers conically from an upper radially outwardly directed collar or flange 2 towards a bottom with a radially inward extending collar or flange 3. The wall la is made of a thermoplastic material and is homogeneous and not permeable. Thus, the wall is gas and liquid tight. The inward directed collar or flange 3 defines a circular opening 4 in the center of the base of the container 1. A circular disk of gas or liquid permeable material, such as a disk of porous paper or the like, where the disk has a larger diameter than the diameter of the opening 4 is attached to the flange 3 by means of an adhesive or by heat sealing around the peripheral edge 6 of the flange 3, so that the opening 4 is closed. The disk 5 serves in this container as a filter element.
Mens ved beholderen som er vist på fig. 1 og 2 åpningen 4 er utformet i basisen av beholderen og er tildekket av et gass- eller væskepermeabelt materiale, skal det forstås at en beholder fremstilt i samsvar med oppfinnelsen ganske enkelt kan ha en frilagt åpning som kan utstrekkes over hele basisflaten eller bare over en del av basisflaten, eller alternativt kan basisflaten til beholderen være utstyrt med et antall små åpninger eller perforeringer. Således kan sideveggen og basisen til beholderen også fremstilles som en enhet-lig konstruksjon, f. eks. av termoplastisk materiale, idet basisen til beholderen er utstyrt med et stort antall fine perforeringer ved hjelp av egnede innretninger under eller etter formingen eller støpetrinnet. Whereas in the case of the container shown in fig. 1 and 2 the opening 4 is formed in the base of the container and is covered by a gas or liquid permeable material, it should be understood that a container manufactured in accordance with the invention can simply have an exposed opening which can extend over the entire base surface or only over a part of the base surface, or alternatively the base surface of the container may be provided with a number of small openings or perforations. Thus, the side wall and the base of the container can also be produced as a unitary construction, e.g. of thermoplastic material, the base of the container being provided with a large number of fine perforations by means of suitable devices during or after the shaping or casting step.
Etter nå å ha beskrevet produktene som fremstilles ved fremgangsmåten i samsvar med oppfinnelsen, skal det beskri-ves, en spesiell prosess under henvisning til fig. 3 - 5 av tegningene. Having now described the products produced by the method in accordance with the invention, a special process shall be described with reference to fig. 3 - 5 of the drawings.
Fig. 3 viser et .yakuumf ormingsverktøy 7. Verktøyet bestemmer en avtrapning i.sin øvre flate og er utstyrt med ka-naler 8 som står i. forbindelse med avtrapningen og som tjener til å trekke ut luft fra denne avtrapning. Ved bruk av verk-tøyet blir en bane 9 av termoplastisk materiale oppvarmet og fremført trinnvis til den viste formingsstasjon, hvor, slik det blir beskrevet nedenfor, den blir varmformet og stanset ved hjelp av samvirkende elementer som beveger seg i forhold til hverandre. Ved .en foretrukket maskin., for utøvelse av frem-gansmåten i samsvar med oppfinnelsen benyttes to formingsverk-tøy 7, idet det ene verktøy bringes til driftsstilling ved formingsstasjonen som skal benyttes ved fremstillingen av en beholder, mens det andre formingsverktøy samtidig beveges til en utleveringsstasjon hvor en beholder fremstilt i verktøyet blir fjernet fra verktøyet. Igjen under henvisning til fig. 3 vil etterhvert som den oppvarmede bane av termoplastisk materi^ale 9 bringes til formingsstasjonen og luft trekkes ut fra avtrapningen som bestemmes i verktøyet 7 gjennom kanalene 8, det oppvarmede materiale trukkét ned i avtrapningen og således inn-tar den form som svarer til utformingen som bestemmes av avtrapningen, som er selvfølgelig formen for beholderen. Som det fremgår av fig. 3, er det utformet to spor i verktøyet 7, idet ett spor er plassert i den øvre flate av verktøyet som om-gir omkretsen av avtrapningen, og det andre er utformet i den del av verktøyet som bestemmer avtrapningen. Disse spor inne-holder fyllinger av ettergivende materiale 10, 11. Et stanse-verktøy 12 er anordnet og beregnet på å stanse ut og kutte ut Fig. 3 shows a yakuum forming tool 7. The tool determines a taper in its upper surface and is equipped with channels 8 which are in connection with the taper and which serve to extract air from this taper. When using the tool, a web 9 of thermoplastic material is heated and advanced step by step to the forming station shown, where, as will be described below, it is hot-formed and punched by means of interacting elements which move in relation to each other. In the case of a preferred machine, for carrying out the method in accordance with the invention, two forming tools 7 are used, one tool being brought into operating position at the forming station to be used in the production of a container, while the other forming tool is simultaneously moved to a dispensing station where a container produced in the tool is removed from the tool. Again with reference to fig. 3, as the heated web of thermoplastic material 9 is brought to the forming station and air is extracted from the step-off determined in the tool 7 through the channels 8, the heated material will be drawn down into the step-off and thus take on the shape that corresponds to the design that is determined by the taper, which is of course the shape of the container. As can be seen from fig. 3, two grooves are formed in the tool 7, one groove being placed in the upper surface of the tool which surrounds the circumference of the taper, and the other is formed in the part of the tool which determines the taper. These grooves contain fillings of compliant material 10, 11. A punching tool 12 is arranged and designed to punch out and cut out
det termoplastiske materiale fra banen 9 når det er foretatt en forming. Stanse- og kutteverktøyet 12 innbefatter to sirkulære kutteblad 13, 14. Kuttebladet..: 13 innrettes i forhold til den ettergivende fylling 10, og kuttebladet 14 innrettes i forhold til den ettergivende fylling 11. Når stanse- og kutteverktøyet 12 beveges nedover, vil kuttebladet 13 skjære gjennom den termoplastiske materialbane S:/ .hvor..-..banen -. 9 erviriko.ntakkcmed.-den ettergivende fylling 10 og således tjener til å adskille beholderen fra den resterende del av banen 9. Det andre kutteblad 14 kutter gjennom den formede del av banen i området som er i kontakt med den ettergivende fylling 11 og kutter således en sirkulær skive ut av basisen av beholderen og bestemmer således åpningen 4 som befinner seg i basisen av beholderen. Da de to kutteblad 13, 14 kutter gjennom deler av banen som er under-støttet av de ettergivende fyllinger 10, 11, vil stanse- og the thermoplastic material from the web 9 when a molding has been carried out. The punching and cutting tool 12 includes two circular cutting blades 13, 14. The cutting blade..: 13 is aligned in relation to the compliant filling 10, and the cutting blade 14 is aligned in relation to the compliant filling 11. When the punching and cutting tool 12 is moved downwards, the cutting blade will 13 cut through the thermoplastic material path S:/ .where..-..the path -. 9 erviriko.ntakkcmed.-the compliant filling 10 and thus serves to separate the container from the remaining part of the web 9. The second cutting blade 14 cuts through the shaped part of the web in the area that is in contact with the compliant filling 11 and thus cuts a circular disc out of the base of the container and thus determines the opening 4 located in the base of the container. When the two cutting blades 13, 14 cut through parts of the web which are supported by the yielding fillings 10, 11, punching and
kuttetrinnet kunne, finne sted samtidig ved to innbyrdes av-trappede, nivåer. Dette er tilnærmet umulig ved vanlige ut-~-.-..u.j stansingsmetoder hvor et avdelende stansetrinn gjennomføres mot en hård eller stiv anslagsflate. Den ovenfor beskrevne fremgangsmåte med bruk av ettergivende anslagsflater tillater en relativt høy toleranse mellom plasseringen"av de to an-slagsf later. Det er blitt funnet at forskjeller opp til flere tiendedels millimeter ikke hindrer et tilfredsstillende utstansingstrinn. Fortrinnsvis imidlertid blir kuttekantene 13, 14 oppvarmet, da dette letter driften av innretningen. the cutting step could take place simultaneously at two mutually staggered levels. This is virtually impossible with normal out-~-.-..u.j punching methods where a dividing punching step is carried out against a hard or rigid impact surface. The method described above with the use of yielding abutment surfaces allows a relatively high tolerance between the location of the two abutment surfaces. It has been found that differences of up to several tenths of a millimeter do not prevent a satisfactory punching step. Preferably, however, the cutting edges 13, 14 are heated , as this facilitates the operation of the device.
Som det fremgår av fig. 3 er bunnen til avtrapningen som er utformet i verktøyet 7 utstyrt med en åpen åpning 15. Som det fremgår av fig. 4 er denne åpning 15 forbundet med en ledning 16 i hvilken det er montert en egnet ventil 17. Ledningen 16 er forbundet med en undertrykkskilde eller partiell undertrykkskilde, såsom en vifte. Under det ovenfor beskrevne vakuumformingstrinn er ventilen 17 holdt lukket. Da en viss mengde luft er tilstede i ledningen 16 mellom den lukkede ventil 7 og avtrapningen .i formen, vil den del av banen 9 som trekkes ned i basisen til avtrapningen i formen ikke su-ges ned gjennom åpningen 15, men forblir i en i det vesentlige plan form. Det skal bemerkes at denne basisdel ikke forblir fullstendig flat, men vanligvis danner en lett nedoverrettet utbukning 18, da denne del av banen 9 ikke har noen flate som understøttelse under formingstrinnet. Dette er imidlertid av liten betydning, da, som beskrevet nedenfor, denne del av banen blir fjernet og ikke utgjør en del av den ferdige beholder. As can be seen from fig. 3, the bottom of the taper formed in the tool 7 is equipped with an open opening 15. As can be seen from fig. 4, this opening 15 is connected to a line 16 in which a suitable valve 17 is mounted. The line 16 is connected to a negative pressure source or partial negative pressure source, such as a fan. During the vacuum forming step described above, the valve 17 is kept closed. Since a certain amount of air is present in the line 16 between the closed valve 7 and the step-off in the mold, the part of the path 9 which is drawn down into the base of the step-off in the mold will not be sucked down through the opening 15, but remains in a the essential plan form. It should be noted that this base part does not remain completely flat, but usually forms a slight downward bulge 18, as this part of the web 9 has no surface for support during the forming step. However, this is of little importance since, as described below, this part of the web is removed and does not form part of the finished container.
Ved fullføring av stansetrinnet blir ventilen 17 åpnet. Undertrykk eller partielt undertrykk står således i forbindelse med åpningen 15, og på grunn av forskjellen mellom trykket i det indre av avtrapningen og formen 7 og trykket i ledningen 16, vil den utstansede skive 18 trekkes gjennom ledningen 16 forbi ventilen 17 til en egnet oppsamlingsinnret-ning. Upon completion of the punching step, the valve 17 is opened. Negative pressure or partial negative pressure is thus connected to the opening 15, and due to the difference between the pressure in the interior of the taper and the mold 7 and the pressure in the line 16, the punched disc 18 will be drawn through the line 16 past the valve 17 to a suitable collection device nothing.
Den ovenfor beskrevne formingsprosess gir således en beholder som er utformet i ett av et termoplastisk materiale med en sidevegg og en øvre utoverrettet flens og en nedre innoverrettet flens. Det skal forstås at ved benyttelsen a<y>den ovenfor beskrevne metode kan det fremstilles beholdere med betydelig nøyaktighet med den øvre og nedre flens riktig sent-rert og med den sentrale bunnskive nøyaktig stanset ut. Imidlertid kan beholderne fremstilles hurtig og billig. The above-described forming process thus provides a container which is formed in one of a thermoplastic material with a side wall and an upper outwardly directed flange and a lower inwardly directed flange. It is to be understood that by using the method described above, containers can be produced with considerable accuracy with the upper and lower flange correctly centered and with the central bottom disk accurately punched out. However, the containers can be manufactured quickly and cheaply.
En skive 5, f. eks. en skive som virker som et filterelement, som beskrevet i forbindelse med fig. 1 og 2, kan lett bli forbundet med beholderen som fremstilt etter den oven-nevnte metode. Som vist på fig. 5 kan et verktøy 19 bli be-nyttet som har en sirkulær del som understøtter en skive 5, idet den del av verktøyet 19 som understøtter skiven er oppvarmet. Verktøyet kan bli beveget, slik at omkretsen av skiven 5 bringes til kontakt med den innoverrettede flens•.: som er til-dannet ved basisen av beholderen, og på grunn av det faktum at verktøyet er oppvarmet, vil skiven 5 bli termosveiset til beholderen. A disc 5, e.g. a disc which acts as a filter element, as described in connection with fig. 1 and 2, can easily be connected to the container as produced by the above-mentioned method. As shown in fig. 5, a tool 19 can be used which has a circular part which supports a disc 5, the part of the tool 19 which supports the disc being heated. The tool can be moved so that the circumference of the disk 5 is brought into contact with the inward flange formed at the base of the container and due to the fact that the tool is heated, the disk 5 will be thermowelded to the container.
Som det er vist på fig. 6 kan, hvis ønsket, verk-tøyet 19 til å begynne med være utstyrt med et ark 20 av papir eller lignende for dannelsen av skiven 5 som er overdimensjo-nert. Verktøyet 19 sammen med arket 2 0 kan så passere gjennom en stanse 21 som er plassert over verktøyet 7, idet stansen 21 og verktøyet 19 samvirker for tilveiebringelse av en skive 5 med ønsket størrelse. Verktøyet 19 kan også benyttes som et element for utsortering og stabling av beholdere etter fremstilling, hvis dette er ønsket. As shown in fig. 6, if desired, the tool 19 can initially be equipped with a sheet 20 of paper or the like for the formation of the disc 5 which is oversized. The tool 19 together with the sheet 20 can then pass through a punch 21 which is placed above the tool 7, the punch 21 and the tool 19 cooperating to provide a disc 5 of the desired size. The tool 19 can also be used as an element for sorting and stacking containers after production, if this is desired.
På fig. 7 er det vist et ytterligere verktøy for bruk ved en fremgangsmåte i samsvar med foreliggende oppfinnelse. Det viste verktøy 7 har to avtrapninger i hvilke elementer av en oppvarmet termoplastisk materialbane 9 kan trekkes inn ved hjelp av et undertrykk. Et kutte- og stanseverktøy 12 er utformet med oppvarmede kuttekanter 13, 13a, som svarer til de som er beskrevet ovenfor, som kutter gjennom områder av banen som er understøttet av ettergivende anslagsflater. In fig. 7 shows a further tool for use in a method in accordance with the present invention. The tool 7 shown has two tapers in which elements of a heated thermoplastic material web 9 can be drawn in by means of a negative pressure. A cutting and punching tool 12 is designed with heated cutting edges 13, 13a, corresponding to those described above, which cut through areas of the web which are supported by yielding abutment surfaces.
I den her viste anordning er imidlertid verktøyet 12 utstyrt med to perforerende elementer 12a, 12b, hvor hvert perforerende element omfatter en skiveformet del som er utstyrt med et antall nedoverrettede oppvarmede stifter 22, som er beregnet på å innsettes i materialet som bestemmer basisen .til beholderen, mens beholderen fremdeles, er i formen. Basisen til avtrapningen som bestemmes i. formen 7 er utformet av et ettergivende materiale 24. Det fremgår at ved bruk av verktøyet vist på fig. 7, vil perforeringene tilformes i basisen til de fremstilte beholdere samtidig med avdelingen av beholderne fra resten av banen 9. Fig. 8 illustrerer en beholder fremstilt av verktøyet som er vist på fig. 7 og viser perforeringer 20 utformet i basisen av beholderen. In the device shown here, however, the tool 12 is equipped with two perforating elements 12a, 12b, where each perforating element comprises a disc-shaped part which is equipped with a number of downwardly directed heated pins 22, which are intended to be inserted into the material which determines the base .to the container, while the container is still in the mold. The base of the taper which is determined in the mold 7 is formed from a yielding material 24. It appears that when using the tool shown in fig. 7, the perforations will be formed in the base of the produced containers at the same time as the separation of the containers from the rest of the web 9. Fig. 8 illustrates a container produced by the tool shown in fig. 7 and shows perforations 20 formed in the base of the container.
Det skal forstås at perforeringene 20 som er utfor.-... met i basisen av beholderen kan utformes ved perforering mot en stiv støtteflate og kan således utformes ved hjelp av ultralyd. Perforeringstrinnet kan også utformes ved en stasjon som er adskilt fra formingsstasjonen. Alternativt kan per-foreringsverktøyet være plassert ved utleveringsstasjonen hvor de fremstilte beholdere blir fjernet fra formen og kan således bli kombinert med en stablingsanordning isteden for å bli kombinert med stansefunksjonen som vist på fig. 7. Fig. 9 illustrerer en ytterligere utførelse av en beholder fremstilt i samsvar med oppfinnelsen, hvor beholderen har i det vesentlige rektangulær form og har forsterknings-ribber eller^aystivende ribber 21, som utstrekker seg tvers over basisflaten. Hensiktsmessig kan basisdelen 23 helt eller delvis stanses ut under fremstillingen av beholderen, eller disse deler kan bli perforert. I alle tilfeller kan områdene av basisen mellom forsterkningselementene 21 bli tildekket av et gass- eller væskegjennomtrengelig materiale. Fig. 10 illustrerer en ytterligere utførelse av en beholder fremstilt i samsvar med oppfinnelsen, idet den illu-strerte beholder er beregnet for bruk som en tesil. Det skal bemerkes at to i det vesentlige rektangulære horisontale fremspring 25, 26 er utformet i ett med sideveggen til beholderen 1 og er tilstrekkelig stive til å gi beholderen støtte over en gjenstand, såsom en tekopp, mens den benyttes som en tesil. It should be understood that the perforations 20 which are formed in the base of the container can be formed by perforating against a rigid support surface and can thus be formed using ultrasound. The perforation step can also be designed at a station that is separate from the forming station. Alternatively, the perforating tool can be located at the dispensing station where the manufactured containers are removed from the mold and can thus be combined with a stacking device instead of being combined with the punching function as shown in fig. 7. Fig. 9 illustrates a further embodiment of a container manufactured in accordance with the invention, where the container has an essentially rectangular shape and has reinforcing ribs or stiffening ribs 21, which extend across the base surface. Appropriately, the base part 23 can be completely or partially punched out during the manufacture of the container, or these parts can be perforated. In all cases, the areas of the base between the reinforcement elements 21 can be covered by a gas or liquid permeable material. Fig. 10 illustrates a further embodiment of a container produced in accordance with the invention, the illustrated container being intended for use as a tea strainer. It should be noted that two substantially rectangular horizontal projections 25, 26 are integrally formed with the side wall of the container 1 and are sufficiently rigid to give the container support over an object, such as a tea cup, while it is being used as a tea strainer.
Det skal anføres at beholderen vist på fig. 10 også kan benyttes som en traktinnretning. Således kan beholderen f. eks. fylles med en egnet mengde av uttrekningsmateriale, såsom kaffe, deretter kan et væskepermeabelt tildekningsstykke i form a<y>et egnet ark bli. montert på plass over den åpne øvre munndel a<y>beholderen. Deretter kan kaffe tilveiebringes ved å helle kokende vann gjennom det væskepermeable tildekningsark og således gjennom kaffen som er anbragt i beholderen, og således vil traktevannet forlate beholderen gjennom den permeable basis. Selvføglelig kan andre materialer enn kaffe trekkes ut på denne måte. It should be stated that the container shown in fig. 10 can also be used as a funnel device. Thus, the container can e.g. is filled with a suitable amount of extraction material, such as coffee, then a liquid-permeable covering piece in the form of a suitable sheet can be made. mounted in place over the open upper mouth part a<y>the container. Coffee can then be provided by pouring boiling water through the liquid permeable cover sheet and thus through the coffee placed in the container, and thus the funnel water will leave the container through the permeable base. Naturally, materials other than coffee can be extracted in this way.
Fig. 11 illustrerer ytterligere en beholder fremstilt med en fremgangsmåte i samsvar med oppfinnelsen, idet den viste beholder 27 omfatter en potte for anbringelse av frø eller planter. Fire hull 28 er anordnet i basisen til beholderen. Når beholderen er i bruk, dvs. når planter eller frø vokser i beholderen, vil beholderen bli holdt i en egnet hol-der. Det skal forstås at oppfinnelsen, som er beskrevet ovenfor, er blitt beskrevet under henvisning til enkle utførelser for formingsverktøyet. Det skal forstås at formingsverktøyene kan være utstyrt med vanlige kjøleinnretninger. Det skal også anføres at selv om oppfinnelsen er blitt beskrevet under henvisning til verktøy med en eller to avtrapninger, kan verktøyet også benyttes med et stort antall avtrapninger. Det er således klart at en formingsmaskin kan benyttes hvor f. eks. 64 beholdere kan fremstilles i en 4 sekunder lang formingssyklus. Dette tilsvarer en total produksjonshastighet på 9 60 beholdere pr. minutt. Det skal forstås at dette nivå for utbytte betyr en billig masseproduksjon av beholdere. Fig. 11 further illustrates a container produced with a method in accordance with the invention, the shown container 27 comprising a pot for placing seeds or plants. Four holes 28 are provided in the base of the container. When the container is in use, i.e. when plants or seeds grow in the container, the container will be kept in a suitable holder. It should be understood that the invention, which is described above, has been described with reference to simple embodiments for the forming tool. It should be understood that the forming tools may be equipped with conventional cooling devices. It should also be stated that although the invention has been described with reference to tools with one or two steps, the tool can also be used with a large number of steps.
