Description

Emballasje for sinkplaster, forbindinger o. 1. Packaging for zinc plaster, bandages etc. 1.

Foreliggende oppfinnelse angår en The present invention relates to a

emballasje av plast, platemateriale e.l. for sinkplaster, isoleringstaånd og andre bånd- eller trådformede materialer, hvilken emballasje består av to, mot hverandre passede, skålformede lokk som omslutter en rull med foreliggende materiale. plastic packaging, plate material etc. for zinc plaster, insulation tape and other strip or thread-shaped materials, which packaging consists of two, mutually fitted, bowl-shaped lids enclosing a roll of the present material.

Det problem som oppfinnelsen er be-stemt for å løse er å tilveiebringe en for omtalte materialer beregnet emballasje, som kan åpnes og stenges bekvemt med én og samme hånd, som samtidig holder emballasjen. Emballasjen skal dessuten være av endel konstruksjon og billig i frem-stilling, slik at den egner seg for masse-produksjon. The problem that the invention is intended to solve is to provide a packaging intended for the materials mentioned, which can be opened and closed conveniently with one and the same hand, which at the same time holds the packaging. The packaging must also be of solid construction and cheap to manufacture, so that it is suitable for mass production.

Overnevnte problem er ifølge oppfinnelsen løst ved at emballasjens to lokk er således utformet at de har en i seg værende strebning for med kneppvirkning over en mellomliggende dødpunktstilling å innta According to the invention, the above-mentioned problem is solved by the fact that the packaging's two lids are designed in such a way that they have an inherent tendency to occupy an intermediate dead center position with a snap action

én av to stabile hvilestillinger, nemlig dels en hvilestilling hvor lokkene har konveks, utadhvelvet form og ligger an mot hverandre langs sine kanter, slik at emballasjen er stengt, og dels en hvilestilling hvor lokkene har konkav, innadhvelvet form, one of two stable rest positions, namely a rest position where the lids have a convex, outwardly domed shape and rest against each other along their edges, so that the packaging is closed, and a rest position where the lids have a concave, inwardly domed shape,

slik at emballasjen er åpen. De to lokk er omstillbare fra sin konvekse til konkave form gjennom utøvelse av sentrale, mot hverandre rettede trykk på lokkene og omstillbare til sin konvekse form ved sam-menføring av lokkenes kanter. Videre er den materialet bærende rulls bredde og radius således avpasset at rullens omkretskanter danner opplagringer for lokkene for å muliggjøre nevnte kneppvirkning av so that the packaging is open. The two lids are adjustable from their convex to concave shape through the application of central, mutually directed pressure on the lids and adjustable to their convex shape by bringing the edges of the lids together. Furthermore, the width and radius of the material-carrying roll are adjusted in such a way that the circumferential edges of the roll form supports for the lids to enable the aforementioned snap action of

disse. Til slutt er lokkene forbundet med these. Finally, the lids are connected with

hverandre ved hjelp av en kopling, som er således anordnet at den tillater en aksiell bevegelse mellom lokkenes sentrale deler ved deres omstilling. each other by means of a coupling, which is arranged in such a way that it allows an axial movement between the lids' central parts during their adjustment.

Oppfinnelsen vil bli forklart nærmere i den følgende del av beskrivelsen under henvisning til tegningen. Fig. 1 viser en emballasje ifølge oppfinnelsen sett fra siden, og fig. 2 og 3 viser tverrsnitt gjennom emballasjen i stengt resp. åpen stilling. The invention will be explained in more detail in the following part of the description with reference to the drawing. Fig. 1 shows a packaging according to the invention seen from the side, and Fig. 2 and 3 show cross-sections through the packaging in closed or open position.

Som det fremgår av tegningen består emballasjen ifølge oppfinnelsen av to, mot hverandre passede, skålformede lokk 1 og 2, som sammen omslutter en rull 3 med det foreliggende bånd- eller trådformede materiale. Lokkene 1 og 2 er fremstilt av et elastisk eller stivt materiale, såsom kunstplast, patemateriale eller lignende, og er således utformet at de har en i seg værende søkning for med kneppvirkning å innta én av to stabile hvilestillinger, nemlig dels en hvilestilling hvor lokkene har konveks, utadhvelvet form og ligger an mot hverandre langs sine kanter, slik at emballasjen er stengt, og dels en hvilestilling hvor lokkene har konkav, innadhvelvet form, slik at lokkantene befinner seg i maksimal avstand fra hverandre og emballasjen er åpen for uttak av innholdet. Lokkene 1 og 2 er omstillbare fra sin konvekse form i stengt stilling til sin konkave form i åpen stilling gjennom utøvelse av sentrale, mot hverandre rettede trykk på lokkenne og omstillbare tilbake tii sin konvekse form ved sammenføring av lokkantene. Lokkene 1 og 2 er forbundet med hverandre ved hjelp av en kopling, som er således anordnet at den tillater en aksiell bevegelse mellom lokkenes sentrale deler ved omstillingene. Koplingen består dels av en sentralt på det ene lokk 1 festet, innadrettet hylse 4 av elastisk materiale, As can be seen from the drawing, the packaging according to the invention consists of two cup-shaped lids 1 and 2 that fit against each other, which together enclose a roll 3 of the existing strip or thread-shaped material. The lids 1 and 2 are made of an elastic or rigid material, such as synthetic plastic, pate material or the like, and are designed in such a way that they have an inherent search for, with a snap action, to assume one of two stable resting positions, namely a resting position where the lids have convex, outwardly domed shape and lie against each other along their edges, so that the packaging is closed, and partly a resting position where the lids have a concave, inwardly domed shape, so that the lid edges are at the maximum distance from each other and the packaging is open for removal of the contents. The lids 1 and 2 are adjustable from their convex shape in the closed position to their concave shape in the open position through the application of central, mutually directed pressure on the lids and adjustable back to their convex shape by bringing the lid edges together. The lids 1 and 2 are connected to each other by means of a coupling, which is arranged in such a way that it allows an axial movement between the central parts of the lids at the transitions. The coupling partly consists of an inwardly directed sleeve 4 of elastic material attached centrally to one lid 1,

f. eks. plast, som i sin frie, indre ende har en innvendig ansats 8, og dels av en i hylsen 4 innført, sentralt på det annet lokk 2 festet, innadrettet tapp 5. Tappens 5 frie, indre ende har en konisk spiss med en utvendig ansats 6. Ved foten av tap- e.g. plastic, which at its free, inner end has an internal projection 8, and partly by an inwardly directed pin 5 inserted in the sleeve 4, centrally attached to the second lid 2. The free, inner end of the pin 5 has a conical tip with an external projection 6. At the foot of the loss-

pen 5 er anbragt en krave 7. Tappen 5 er aksielt forskyvbar i hylsen 4, idet beve- pin 5 is fitted with a collar 7. The pin 5 is axially displaceable in the sleeve 4, as

gelsen i den ene retningen begrenses av kravens 7 anlegg mot hylsens 4 frie ende og i den andre retningen av ansatsens 6 the gel in one direction is limited by the contact of the collar 7 against the free end of the sleeve 4 and in the other direction by the attachment 6

anlegg mot hylsens 4 innvendige ansats 8, hvorved tappen 5 er forhindret fra uønsket utglidning av hylsen 4. against the sleeve 4's internal shoulder 8, whereby the pin 5 is prevented from undesired sliding of the sleeve 4.

Rullen 3, som bærer det bånd- eller trådformede materiale, er utført av papp, The roll 3, which carries the strip or thread-shaped material, is made of cardboard,

plast, tre e. 1. og er ved hjelp av et nav 9 aksielt forskyvbar samt roterbart an- plastic, wood e. 1. and is axially displaceable and rotatable by means of a hub 9

ordnet på hylsen 4. Rullens 3 bredde og radie er således avpasset at dens omkretskanter danner hensiktsmessige opplagrin- arranged on the sleeve 4. The width and radius of the roller 3 are adjusted in such a way that its peripheral edges form suitable storage

Navets 9 lengde er videre kortere enn bredden av rullen 3, slik at lokkenes 1,2 sentrale deler fritt kan innføres innenfor et plan gjen- Pressure directed towards each other on the lids or joining the lid edges. The length of the hub 9 is further shorter than the width of the roller 3, so that the central parts of the lids 1,2 can be freely introduced within a plane re-

Ved sammensettingen av emballasjen, innsettes den med det bånd- eller trådformede materiale forsynte rull 3 med sitt nav 9 på hylsen 4 i det ene, i konveks form værende lokk 1. Det andre lokk 2, When assembling the packaging, the roll 3 provided with the tape or thread-shaped material is inserted with its hub 9 on the sleeve 4 in one, convexly shaped lid 1.

Lengden av tappen 5 er også hensiktsmessig således avpasset at de to lokk 1, 2 insert 6 into the sleeve 4, whereby the elastic material of the sleeve 4 allows the attachment to be guided through the internal attachment 8. The length of the pin 5 is also suitably adapted so that the two lids 1, 2
