Den foreliggende opfindelse angår en fremgangsmåde til fremstilling af et låg til en beholder forsynet med en skjult hældetud og en støbeform til udøvelsen af denne fremgangsmåde, således som angivet i indledningen til krav 1.The present invention relates to a method of producing a lid for a container provided with a concealed pour spout and a mold for the practice of this method, as set forth in the preamble of claim 1.
55
Det er kendt at emballere flydende eller pulveriserede produkter i beholdere forsynet med tætte låg og at forsyne disse med en hældetud, der lukkes med et dæksel og en prop eller hætte. Det er kendt at vende deres cylindrisk-koniske del som fingertut. Man undgår således ethvert fremspring på hældetuden og dens prop eller hætte over dækselets øverste overflade, hvilket især letter stabling og oplagring af beholderne.It is known to package liquid or powdered products in containers fitted with tight lids and to provide them with a pour spout that closes with a cover and a stopper or cap. It is known to turn their cylindrical-tapered portion as a fingertip. Thus, any protrusion on the pour spout and its plug or cap over the top surface of the cover is avoided, which in particular facilitates stacking and storage of the containers.
Ved de udførelsesformer, som er kendt i dag, er hældetuden støbt for sig selv i blød plast og er derpå fastgjort på en 15 sådan måde, at et hul i låget tilstoppes. Dette medfører en operation, hvorved hældetuden placeres, og kræver forholdsregler for at sikre en god mekanisk fastgørelse og en god tæthed mellem låget og hældetuden.In the embodiments known today, the pour spout is molded for itself in soft plastic and is then secured in a manner such that a hole in the lid is clogged. This results in an operation whereby the pour spout is placed and requires precautions to ensure a good mechanical fastening and a good tightness between the lid and the pour spout.
20 Fra FR-patent nr. 2.412.400 kendes allerede en fremgangsmåde til støbning af tofarvede beholdere, hvori man - for at opnå en synlig sammenføjningszone, der er relativ glat på overfladen - udføre en indsprøjtning med et forudbestemt rumfang af materialet af den første farve, indtil overgangszonen, som man 25 vælger tyk og man foretager derefter en indsprøjtning af materialet af den anden farve, som man lader stivne og indtrænge i midten af den ekstra tykkelse af det første stof under størkningen. Det drejer sig imidlertid her om plastmaterialer af identiske kvaliteter i forskellige farver, og disse materialer 30 kan fuldstændig forbinde sig og det eneste problem, som skal løses, vedrører det glatte udseende af overfladen omkring forbindelsen.20 From FR Patent No. 2,412,400, a method of casting two-color containers is already known in which - in order to obtain a visible joining zone which is relatively smooth on the surface - an injection with a predetermined volume of the material of the first color is carried out. until the transition zone, which one chooses thick and then an injection of the material of the second color which is allowed to solidify and penetrate in the middle of the extra thickness of the first substance during solidification. However, these are plastic materials of identical qualities in different colors, and these materials 30 can completely connect and the only problem to be solved concerns the smooth appearance of the surface around the compound.
Fra DE-patent nr. 21 10 156 kendes endvidere en fremgangsmåde 35 til støbning af sammensatte stykker dannet af forskellig plastmaterialer med indsnævringer ved deres indbyrdes forbindelse, men som på stedet for denne forbindelse ikke har væsentlige tykkelsesforskelle. Ved denne kendte teknik er forbindelsen 2Furthermore, from DE-patent No. 21 10 156 there is known a method 35 for casting composite pieces formed from different plastics materials with narrowings at their interconnection, but which have no significant thickness differences at the site of this connection. In this prior art, the compound is 2

realiseret ved et snævert anlæg mellem to materialer, hvoraf det ene støbes oven på det andet, kant mod kant, og som ikke vil kunne glide senere ved dannelse af en lille funge af det andet materiale, som trænger lidt ind i det første materiale, 5 før det er fuldstændigt stivnet. Med en sådan fremgangsmåde er det imidlertid ikke muligt at opnå en fuldstændig tæthed af forbindelsen og heller ikke at realisere en forbindelse mellem stykker af forskellig tykkelse og med forskellig blødhed.realized by a narrow abutment between two materials, one of which is cast on top of the other, edge to edge, and which will not be able to slip later by forming a small prong of the second material, which penetrates slightly into the first material, 5 before it is completely stiffened. However, with such a method, it is not possible to achieve a complete density of the joint nor to realize a connection between pieces of different thickness and with different softness.
1 Det er formålet med opfindelsen at tilvejebringe et låg, som består af en første art plastmateriale af en kvalitet, der er velegnet til beholderens anvendelse, og hvor låget er forsynet med en støbt hældetud i et andet blødt plastmateriale af en kvalitet, som muliggør, at den skjules under låget, og hvor låget og hældetuden danner ét og samme stykke, der er frem-bragt direkte ved støbningen af låget, hvorved der sikres en god mekanisk forbindelse mellem låget og hældetuden og en fuldstændig tæthed ved forbindelsen mellem låg og hældetud.SUMMARY OF THE INVENTION It is an object of the invention to provide a lid which consists of a first kind of plastic material of a quality suitable for the use of the container, and in which the lid is provided with a molded pouring spout in a second soft plastic material of a quality which enables, that it is concealed under the lid and where the lid and pour spout form one and the same piece produced directly by the casting of the lid, thereby ensuring a good mechanical connection between the lid and the pour spout and a complete tightness at the connection between the lid and pour spout.
Ifølge opfindelsen anvises en fremgangsmåde til fremstilling 20 af et beholderlåg med en skjult hældetud, og ved hvilken låget med undtagelse af hældetuden støbes i et første materiale af en kvalitet, der er egnet til beholderens anvendelse, op til en grænse, der omgiver hældetudens fod, og hvorved hældetuden støbes af et fleksibelt plastmateriale af en kvalitet, der 25 er egnet til beholderens anvendelse. Fremgangsmåden er ejendommelig ved, at låget og hældetuden støbes i en enkelt form, og at låget støbes før hældetuden og består af et plastmateriale, som er mindre fleksibelt end materialet hældetuden, og at de to plastmaterialer, som er indbyrdes forenelige, for-3 0 bindes ved at påvirke det andet plastmateriale til at trænge ind i kernen af et ekstra tykt område, indrettet til formålet i det første plastmateriale, omkring foden for hældetuden og før en væsentlig størkning af det første plastmateriale, og ved at det andet plastmateriale påvirkes til at trænge ind i 35 og lukke sig væsketæt inde i kernen af det nævnte ekstra tykke område af det første plastmateriale ved afslutningen af støbningen af det andet materiale. På denne måde sikres en god 3According to the invention, a method for making a container lid with a concealed pour spout is disclosed in which the lid, with the exception of the pour spout, is molded in a first material of a quality suitable for the use of the container, up to a border surrounding the foot of the pour spout, and wherein the pouring spout is molded of a flexible plastic material of a quality suitable for the use of the container. The method is characterized in that the lid and pour spout are molded in a single mold, and that the lid is molded before the pour spout and consists of a plastic material which is less flexible than the material pour spout and that the two plastic materials which are mutually compatible are compatible with the pour spout. bonded by influencing the second plastic material to penetrate into the core of an extra thick area, arranged for the purpose of the first plastic material, around the foot of the pouring spout and prior to a substantial solidification of the first plastic material, and by affecting the second plastic material to penetrate 35 and seal tightly within the core of said extra thick area of the first plastic material at the end of the casting of the second material. In this way a good 3 is ensured

forbindelse mellem de to materialer på én gang, dels med hensyn til den mekaniske styrke ved hjælp af en fastlåsning mellem de to materialer, og dels med hensyn til tætheden af forbindelsen på grund af forligeligheden mellem de to anvendte 5 materialer.connection between the two materials at one time, partly with respect to the mechanical strength by means of a lock between the two materials and partly with respect to the density of the connection due to the compatibility of the two materials used.
Ifølge en foretrukken fremgangsmåde ifølge opfindelsen lukker man i støbeformen forbindelsen mellem støberummet for det første materiale og støberummet for det andet materiale, i det 1Q mindste indtil det første materiale i hovedsagen er fuldstændigt indsprøjtet, og ved afslutningen af udstøbningen af det første materiale indsprøjter man det andet materiale, og man åbner den førnævnte forbindelse mellem støberummet for det første materiale og støberummet for det andet materiale. På 15 denne måde kan man iværksætte indtrængningen af det andet materiale i det første materiale på det mest hensigtsmæssige tidspunkt, dvs. efter at det er blevet tilstrækkeligt afkølet, men før det er stivnet for meget.According to a preferred method of the invention, in the mold, the connection between the molding chamber of the first material and the molding chamber of the second material is closed, at least until the first material is substantially completely injected, and at the end of the molding of the first material, the second material, and the aforementioned connection is opened between the molding chamber of the first material and the molding chamber of the second material. In this way, the penetration of the second material into the first material can be initiated at the most convenient time, ie. after it has been sufficiently cooled but before it has solidified too much.
Opfindelsen angår endvidere en støbeform, der muliggør udøv- 20 elsen af den førnævnte fremgangsmåde, idet denne støbeform er ejendommelig ved, at den omfatter en øvre del sammensat af to dele, en indre del og en ydre del, og en nedre del sammensat af tre dele, en ydre del, en indre del, og en ringformet mellemdel, hvilke dele kan adskilles i formens åbningsretning, et 2 5 støberum for den del af låget, som omgiver foden af hældetuden, indrettet mellem de to øvre dele og den ydre, nedre del, et støberum for hældetuden, indrettet mellem den indre, øvre del og den indre, nedre del, og at den mellemliggende nedre del kan bevæges parallelt med formens åbningsretning, uaf-30 hængigt af de andre dele af formen og med en ringform, som kan indføres mellem den indre og den ydre af de nedre dele og indrettet som en lukkedel i relation til den indre, øvre del at lukke eller åbne forbindelsen mellem de to støberum, hvilken forbindelse danner den grænse, der omgiver overgangen fra fod- en af hældetuden til låget. I en foretrukken udførelsesform er konfigurationen af den ringformede lukkedel indrettet således, at der mellem endefladen af lukkedelen og væggen af den til- 35The invention further relates to a mold which enables the aforementioned method to be carried out, said mold being characterized in that it comprises an upper part composed of two parts, an inner part and an outer part, and a lower part composed of three. portions, an outer portion, an inner portion, and an annular intermediate portion which may be separated in the opening direction of the mold, a casting space for the portion of the lid surrounding the foot of the pouring spout arranged between the two upper portions and the outer lower portion part, a pouring spout molding, arranged between the inner, upper part and the inner lower part, and the intermediate lower part can be moved parallel to the opening direction of the mold, independently of the other parts of the mold and with an annular mold which can be inserted between the inner and outer of the lower parts and arranged as a closure member in relation to the inner, upper part to close or open the connection between the two moldings, which forms the boundary surrounding the transition from the foot of the poured outside the lid. In a preferred embodiment, the configuration of the annular closure member is arranged such that between the end surface of the closure member and the wall of the closure member.

Opfindelsen skal i det følgende forklares nærmere under henvisning til tegningen, hvor fig. 1 viser et snit gennem de væsentligste dele af støbeformen for låget i det område, hvor det skal kunne optage hælde- i o tuden, idet støbeformen er vist i en første stilling, der svarer til begyndelsen af fremstillingsprocessen, fig. 2 samme som fig. 1 under det følgende fremsti 11ingstrin, idet skraveringerne af visse dele af støbeformen er udeladt 15 for klarheds skyld, fig. 3 samme som fig. 2 under et følgende fremsti 11ingstrin, fig. 4 samme som fig. 3 under det endelige fremstillingstrin, og 20 fig. 5 et forstørret udsnit af en detalje i fig. 3, betegnet med V.The invention will now be explained in more detail with reference to the drawing, in which 1 shows a section through the main parts of the mold for the lid in the region where it can accommodate the pouring spout, the mold being shown in a first position corresponding to the beginning of the manufacturing process; FIG. 2 the same as FIG. 1 during the following manufacturing step, the shading of certain parts of the mold being omitted 15 for the sake of clarity; 3 the same as FIG. 2 during a subsequent step 11; FIG. 4 the same as FIG. 3 during the final manufacturing step, and FIG. 5 is an enlarged section of a detail of FIG. 3, denoted by V.
I det viste eksempel fremstilles et låg til en beholder for-25 synet med en skjult hældetud i det indre af en støbeform, som i hovedsagen består af stykker, der på tegningen er betegnet med henvisningstallene 1, 2, 3, 4 og 5.In the example shown, a lid for a container is provided with a concealed pouring spout in the interior of a mold which consists essentially of pieces designated in the drawing by reference numerals 1, 2, 3, 4 and 5.
Formen består i hovedsagen af en øvre del dannet af stykkerne 1 og 2 og en nedre del dannet af stykkerne 3, 4 og 5, hvori- 30 mellem der er indrettet støberum til støbning af låget og dets integrerede hældetud. Støbeindretningen til ringen 22 er ikke vist.The mold mainly consists of an upper part formed by the pieces 1 and 2 and a lower part formed by the pieces 3, 4 and 5, between which casting space is provided for molding the lid and its integrated pour spout. The molding device for the ring 22 is not shown.
I den stilling, der er vist i fig. 1, er stykket 5, som danner 35 den ringformede lukkedel af støbeformen, skubbet opad i retning af pilen 6 for at spærre forbindelsen mellem støberummet 7 for det første materiale til låget og støberummet 8 til hældetuden .In the position shown in FIG. 1, the piece 5, which forms the annular closure portion of the mold, is pushed upward in the direction of the arrow 6 to block the connection between the molding chamber 7 of the first material for the lid and the molding chamber 8 for the pouring spout.
DK 152267 BDK 152267 B
5 I denne stilling af støbeformen og i en første tidsperiode indfører man, som angivet med pilen 9, det første plastmateriale i støberummet 7 til dannelse af hele låget med undtagelse af hældetuden. Man bemærker straks, at dette rum har en 5 større højde på det sted, hvor forbindelsen mellem låget og hældetuden skal tilvejebringes, således at der dannes en fortykkelse 10.5 In this position of the mold and for a first period of time, as indicated by the arrow 9, the first plastic material is introduced into the molding chamber 7 to form the entire lid with the exception of the pouring spout. It is immediately noted that this space has a greater height at the place where the connection between the lid and the pour spout is to be provided, so that a thickening 10 is formed.
Ved den på tegningen viste fremgangsmåde standser man ind-sprøjtningen efter afslutningen af denne første indsprøjtningsfase, som skematisk vist med pilen 11 på fig. 2. Derpå frigøres lukkedelen 5 ved at trække denne del nedad, som angivet ved pilen 12. Udformningen af lukkedelen 5 vælges således, at der i lukkedelens åbningsstilling, som vist i fig.In the method shown in the drawing, the injection is stopped after the completion of this first injection phase, as schematically shown by the arrow 11 in FIG. 2. Then, the closure portion 5 is released by pulling this portion downward, as indicated by arrow 12. The design of the closure portion 5 is selected such that in the opening position of the closure portion, as shown in FIG.
2, skabes støberum mellem endefladen 13 af lukkedelen 5 og den faste væg overfor af støbeformen 1 for den længste del af det vendte parti 17 på den skjulte tud under låget. Dette støberum står i forbindelse med rummet 8.2, molding is created between the end surface 13 of the closure portion 5 and the solid wall opposite of the mold 1 for the longest portion of the facing portion 17 of the concealed spout under the lid. This molding room is connected to the compartment 8.
Fra dette øjeblik, og som vist i fig. 3 ved 14, kan man ind- 20 sprøjte det andet bløde plastmateriale, som vil forme hældetuden, der kan skjules. Indsprøjtningen foretages, før det første materiale har haft tid til at stivne form meget, hvilket gør det muligt for materialet til hældetuden at trænge ind i lågmaterialet, som stadig er viskøst, i midten af den for- 25 tykkede del 10, mens der allerede på overfladen har dannet sig en hud. Indtrængningen af de to materialer er vist tydeligt i fig. 5, hvor man har markeret de to materialer på forskellig måde, idet lågmaterialet er betegnet med 15, og hældetudens materiale er betegnet med 16.From this moment, and as shown in FIG. 3 at 14, the second soft plastic material can be injected which will form the concealable pourable spout. The injection is done before the first material has had much time to solidify form, which allows the material for the pouring spout to penetrate the lid material, which is still viscous, in the middle of the thickened part 10, while already on the surface has formed a skin. The penetration of the two materials is clearly shown in FIG. 5, where the two materials have been marked differently, with the lid material being designated 15 and the pouring spout material being designated 16.
30 I fig. 3 ser man tydeligt hældetuden, som består af den bløde del 17, der er vendt som en fingertut med delen 18, som danner hældetuden, og delen 19, som danner lukkedækselet, der kan rives af takket være en ringformet afrivningslinie 20, hvor 35 dækselet 19 er i fast forbindelse med en del 21 på en afrivningsring 22 til dækselet 19. Formen og opbygningen af en sådan afmærket hældetud i sin helhed 25 er i sig selv kendt.In FIG. 3 clearly shows the pouring spout, which consists of the soft portion 17 which is turned like a finger spout with the portion 18 forming the pouring spout, and the portion 19 which forms the closure cover which can be ripped off thanks to an annular tear line 20, wherein the cover 19 is in fixed connection with a portion 21 of a tear-off ring 22 to the cover 19. The shape and structure of such a marked pour spout in its entirety 25 is known per se.

6 Når det andet materiale 16, der danner hældetuden, i tilstrækkelig grad er trængt ind i det første materiale 15, som danner låget 23 på beholderen, standser man denne indtrængning ved, som angivet ved 24 i fig. 4, at etablere et indsprøjtningsmod-5 tryk i det første materiale, således at trykkene udbalanceres. j6 When the second material 16 forming the pouring spout is sufficiently penetrated into the first material 15 which forms the lid 23 on the container, this penetration is stopped, as indicated by 24 in FIG. 4, to establish an injection molding pressure in the first material so that the pressures are balanced. j
Efter en tilstrækkelig afkøling kan man frigøre låget og dets indbyggede hældetud ved at åbne støbeformen.After sufficient cooling, the lid and its built-in pour spout can be released by opening the mold.
Som passende materialer kan man f.eks. til låget 23 anvende en 10 polypropylen eller en polyethylen med høj vægtfylde.As suitable materials, e.g. for the lid 23 use a polypropylene or a high density polyethylene.
Til det andet materiale, der danner hældetuden, kan man anvendes et blødt materiale, som er foreneligt med det første, som f.eks. en copolymer af arten EEA, dvs. En copolymer af 15 ethylen og ethylacrylat, der f.eks. kan indeholde fra 4 til 25% af EA (ethylacrylat) i EEA (copolymer af ethylen og ethyl-acrylat).For the second material forming the pour spout, a soft material which is compatible with the first can be used, e.g. a copolymer of the species EEA, i.e. A copolymer of ethylene and ethyl acrylate, e.g. may contain from 4 to 25% of EA (ethyl acrylate) in EEA (copolymer of ethylene and ethyl acrylate).
Man kan ligeledes til dette andet bløde materiale til hælde-20 tuden anvende en blanding af den førnævnte copolymer EEA og af basismaterialet til låget i et forhold på fra 30 til 100% af copolymeren EEA i blandingen.Also, for this second soft material for the pouring spout, a mixture of the aforementioned copolymer EEA and of the base material for the lid can be used in a ratio of from 30 to 100% of the copolymer EEA in the mixture.
I det andet materiale kan man erstatte stoffet EEA med materialer, som på én gang er forenelige med det første materiale, 25 og som har den nødvendige blødhed, såsom termoplastisk kaut-sjuk af typen polystyren-polybutadien-polystyren (SBS) eller olefinisk kautsjuk, såsom en polymer af ethylen-propylen-dien-monomer (EPDM), eller af typen ethylen-propylen (EPR), ethy- lenpolyvinylacetat eller EVA, ionomere harpikser etc.In the second material, the substance EEA can be replaced with materials which are at once compatible with the first material and which have the necessary softness, such as polystyrene-polybutadiene-polystyrene (SBS) thermoplastic rubber or olefinic rubber, such as a polymer of ethylene-propylene-diene monomer (EPDM), or of the type of ethylene-propylene (EPR), ethylene polyvinyl acetate or EVA, ionomeric resins, etc.

Fremgangsmåden og den anvendte støbeform kan varieres på forskellige måder.The process and the mold used can be varied in various ways.
Hvad angår støbeformen kan man f.eks. indrette det således, at 35 delene 1 og 2 af formen er i fast forbindelse.As for the mold, for example, arrange it so that the parts 1 and 2 of the mold are in fixed connection.
På samme måde kan delene 4 og 5 være i fast forbindelse under forudsætning af, at profilen af delen 4 tillader en tilstrækSimilarly, the parts 4 and 5 may be in fixed connection provided that the profile of the part 4 permits a
