Description

i 143739 oi 143739 o

Opfindelsen angår en blæsestøbt plastbeholder med en i en åbningsrand afsluttet halsdel, hvilken beholder omfatter en radialt udadforløbende yderflange, som er anbragt i en afstand under halsdelens åbningsrand og ind-5 rettet til at danne anlægsflade for en kantflange på et over halsåbningen med mellemlæg af en tætning anbragt låg.BACKGROUND OF THE INVENTION The invention relates to a blow molded plastic container having a neck portion terminated in an opening edge comprising a radially outwardly extending outer flange disposed at a distance below the opening edge of the neck portion and adapted to form abutment surface for an edge flange on an upper neck opening intermediate a seal placed lid.

Når flere fyldte beholdere af denne art er stablet oven på hinanden, vil de lodrette stabelkræfter, der overføres gennem lågene bevirke, at den fra beholderkap-10 pen fremspringende flangerand sammentrykkes og eventuelt så meget, at lågene løsnes fra deres tætnende stillinger.When several filled containers of this kind are stacked on top of one another, the vertical stacking forces transmitted through the lids cause the flange edge protruding from the container housing 10 to be compressed and possibly so much that the lids are released from their sealing positions.

Man har søgt at forstærke beholderens flangerand ved at tilvejebringe langs flangerandens indre omkreds jævnt fordelt anbragte halvkuglekalotformede for-15 dybninger. Herved opnår man, at stabelkræfterne i det væsentlige overføres direkte fra åbningsranden til beholderkappen, idet flangematerialet presses ind i fordybningerne. Flangeranden vil ved denne foranstaltning i det væsentlige ikke blive sammentrykket.Attempts have been made to reinforce the flange edge of the container by providing evenly spaced hemispherical grooves along the inner circumference of the flange edge. In this way, the stacking forces are substantially transferred directly from the opening edge to the container sheath as the flange material is pressed into the recesses. The flange edge will not be substantially compressed by this measure.

20 En sådan beholder har dog den ulempe, at fordybninger ne ikke kan gøres vilkårligt dybe af hensyn til en sikker lagfastgørelse. Beholderens flangerand får tillige en mindre radial stivhed på grund af fordybningerne. Det er derfor på omstændelig måde nødvendigt at stabilisere området ved flange-25 randen ved materialetilsætning i radialretningen. Ved beholderens tømning vil der desuden ofte sidde rester i den hulning som dannes af indersiden af flangeranden.However, such a container has the disadvantage that the recesses cannot be made arbitrarily deep for the sake of a secure layer attachment. The flange edge of the container also has a less radial stiffness due to the recesses. Therefore, it is necessary to stabilize the area at the flange edge by material addition in the radial direction. Furthermore, when emptying the container, there will often be residues in the cavity formed by the inside of the flange rim.

Opfindelsen har til formål at tilvejebringe en blæsestøbt plastbeholder, hvor tætningen mellem låget og 30 beholderranden ikke sammentrykkes for kraftigt, dvs. så kraftigt, at tætnevirkningen forsvinder ved optrædende aksialbelastninger.The invention has for its object to provide a blow molded plastic container where the seal between the lid and the container rim is not too tightly compressed, ie. so strong that the sealing effect disappears with axial loads occurring.

Dette formål opnås ifølge opfindelsen ved en blæsestøbt plastbeholder af den indledningsvis nævnte art, og 35 kendetegnet derved, at yderflangen udgøres af to vægdele af en udadrettet og under en første del af støbningen ind- 2 143739This object is achieved according to the invention by a blow molded plastic container of the kind mentioned above, and characterized in that the outer flange is made up of two wall parts of an outwardly and under a first part of the casting.

ad åben vulst,som er sammenpresset til en massiv vulst, samt at afstanden mellem yderflangens overside og kantflangens underside er mindre end tætningens tykkelse eller højde# når beholderlåget er ubelastet. Ved at for-5 doble yderflangens vægtykkelse opnås større stivhed over for de nævnte aksialkræfter og ved at lade afstanden mellem yderflangens overside og kantflangens underside være mindre end tætningens tykkelse eller højde# når beholderlåget er ubelastet, er der skabt sikkerhed for# at lågets 10 kantflange bringes i anlæg mod den forholdsvis stive flange, inden den nødvendigvis eftergivelige tætning trykkes helt sammen. Hermed forbliver tætningen effektiv selv ved forholdsvis store aksiale belastninger.by an open bead which is compressed into a solid bead, and that the distance between the top of the outer flange and the bottom of the edge flange is less than the thickness or height # of the sealing cap when unloaded. By doubling the wall thickness of the outer flange, greater stiffness is obtained against the said axial forces and by allowing the distance between the top of the outer flange and the underside of the edge flange to be less than the thickness or height # when the container lid is unloaded, security is created for # that the edge flange of the lid 10 be brought into contact with the relatively rigid flange before the necessarily resilient seal is fully compressed. Thus, the seal remains effective even at relatively large axial loads.

Opfindelsen skal i det følgende forklares nærmere 15 under henvisning til tegningen, der viser et længdesnit gennem et øvre hjørne af en i overensstemmelse med opfindelsen udformet beholder med tilhørende låg.The invention will be explained in greater detail below with reference to the drawing, which shows a longitudinal section through an upper corner of a container formed in accordance with the invention with a corresponding lid.

På tegningen er der vist en beholder, som omfatter en beholderkrop 1, hvorfra heholderens øvre del 20 over et jævnt tilspidset område går over i et i det væsentlige lodret ringområde, hvortil den radialt udadrettede, lukkede flange 3 støder. Åbningshalsen 5 stiger op fra flangen 3's inderrand og kan som vist have et bugtet forløb. Låget 2 er lagt oven på åbningshalsen 25 5, og lågets radialt udadrettede yderrandsflange 8 er ved en spændering 4 spændt mod flangeranden 3. Derved trykkes den mellem lågyderranden 6 og låginderranden 7 indlagte tætningsring 9 mod åbningshalsen 5’s overkant.In the drawing, a container is shown which comprises a container body 1, from which the upper part 20 of the holder passes over a smoothly tapered area into a substantially vertical annular area, to which the radially outwardly closed closed flange 3 abuts. The opening neck 5 rises from the inner edge of the flange 3 and may, as shown, have a curved course. The lid 2 is placed on top of the opening neck 25 5, and the radially outward outer edge flange 8 of the lid is tightened against the flange edge 3 by a tension 4, thereby pressing the sealing ring 9 inserted between the lid outer edge 6 and the lid inner edge 7 against the upper edge of the opening neck 5.

30 Ved sprøjtestøbningen anvendes en støbeform, der på gængs måde er opdelt i to formhalvdele, der er symmetriske omkring et i beholderens længderetning forløbende deleplan. Derudover er formhalvdelene imidlertid også opdelt i en øvre og en nedre formdel langs et 35 plan, der forløber vinkelret på beholderens længdeakse og i området nær flangeranden 3. Under en første del 143739In the injection molding, a mold is used which is generally divided into two mold halves that are symmetrical about a part plane extending longitudinally of the container. In addition, however, the mold halves are also divided into an upper and a lower mold portion along a plane extending perpendicular to the longitudinal axis of the container and in the region near the flange edge 3. During a first portion 143739

3 af støbningen er den øvre og den nedre formdel anbragt i en afstand fra hinanden under dannelse af et i tværsnit i hovedsagen rektangulært, udadvendende hulrum, der afgrænser den indad åbne vulst i beholderkappen.3 of the molding, the upper and lower mold members are spaced apart to form a generally rectangular, outwardly extending cavity defining the inwardly open bead of the container sheath.

5 Under en efterfølgende del af støbningen presses de tp formdele sammen under sammensvejsning af de endnu forholdsvis varme vulstindersider for dannelse af den ønskede, forholdsvis tykvæggede flangerand 3.5 During a subsequent part of the molding, the tp molding members are compressed during welding of the still relatively warm bead sides to form the desired, relatively thick-walled flange edge 3.
