Description

Åpne- og lukkeanordning for sammentrykkbare tuber. Opening and closing device for compressible tubes.

Foreliggende oppfinnelse har til hen-sikt å oppnå en enkel og billig åpne- og The aim of the present invention is to achieve a simple and cheap open-and

lukkemekanisme for tuber (dller poser), closing mechanism for tubes (dller bags),

etter at der i tubens forsegling er frem-bragt en åpning, f. eks. ved avklipning av et after an opening has been created in the tube's seal, e.g. by cutting off a

hjørne som vist ved pilen på fig. 1 i ved-føyede tegning, og eventuelt etter at noe corner as shown by the arrow in fig. 1 in the attached drawing, and possibly after something

av tubens innhold er fjernet. of the tube's contents has been removed.

Oppfinnelsen er karakterisert ved at The invention is characterized in that

den enden av tuben (fig. 1 og 5) hvor tøm-meåpningen ligger, er forsynt med et styre-spor a, fremkommet ved selve sveiseopera-sjonen ved tubens fremstilling, hvori en the end of the tube (fig. 1 and 5) where the emptying opening is located, is provided with a guide groove a, produced by the welding operation itself during the tube's manufacture, in which a

klype (fig. 2) innføres. Klypen, som er clip (fig. 2) is introduced. The pinch, that is

fremstillet av fjærende materiale, består made of springy material, consists

av to nær sammenliggende ben b og har et of two closely adjacent legs b and has a

«øye» c i den ene enden, tilstrekkelig stort "eye" c at one end, sufficiently large

ti) å gi den ønskede åpning i tubekanten. ti) to provide the desired opening in the tube edge.

Fig. 3 og 4 viser klypens anvendelse på Fig. 3 and 4 show the use of the clamp

tubeåpningen, hvor fig. 3 viser tuben lukket og fig. 4 tuben åpen. Tuben lukkes ved the tube opening, where fig. 3 shows the tube closed and fig. 4 tube open. The tube is closed by

å skyve klypen opp, hvorved kanalen e to push the pinch up, whereby the channel e

klemmes sammen. Ved å føre klypen helt are squeezed together. By fully advancing the clamp

ned vil kanalen igjen åpnes, idet da åpnin-gen e blir liggende inne i øyet. De skraverte down, the channel will open again, as the opening e will then lie inside the eye. They hatched

feltene er sveiset. the fields are welded.

For å sikre klypens stilling i tubens lukkede tilstand er styresporet a forsynt med To ensure the position of the clamp in the tube's closed state, the guide track a is provided

stoppeknaster d (fig. 1 og 5) i form av stop cams d (fig. 1 and 5) in the form of

forhøyninger, fremkommet ved at partiet d elevations, brought about by the party d

ikke sammensveises og ved hjelp av tryk-ket i tuben. Partiet d fortsetter i et parti not welded together and with the help of the pressure in the tube. The party d continues in a party

x (fig. 1 og 5) som heller ikke er sveiset; x (fig. 1 and 5) which is also not welded;

det (x) vil redved være styresporets a ene it (x) will redved be the a of the control track

langsgående begrensning. Stoppeknastene longitudinal restriction. Stop cams

vil, i tubens lukkede tilstand, gripe inn i tilsvarende fordypninger f i klypen (fig. 2). will, in the tube's closed state, engage in corresponding depressions f in the clip (fig. 2).

Fig. 5 viser et tverrsnitt gjennom tube og sveisesøm ved forhøyningen d. Fig. 5 shows a cross-section through the tube and welding seam at the elevation d.

Claims

1. Opening and closing device for compressible tubes of the kind that consists of a plastic or similar sleeve closed at both ends, where at least one end is closed with a flat welding seam and where the tube is emptied through an e.g. by cutting off a corner of this welding seam, an opening is produced; characterized in that said welding seam is provided with a groove (a) for controlling a displaceable clip arranged in the groove with two spring legs (b) lying close to each other and an eye (c), which clip when displaced in the groove (a) either can be made to close the opening of the tube (e) by means of the spring legs (b) or allow emptying from the tube by bringing the eye (c) to correspond with the emptying opening (e).

2. Opening and closing device for tubes according to claim 1, characterized in that there is an elevation (d) in the groove (a) and extensions (f) in the leg of the clip (b) to ensure the position of the clip in the tube's open or closed state.
