Opfindelsen angår en engangspose til brug ved frysning af formlegemer, navnlig såkaldte isterninger, og bestående af to plastfolier, der er lokalt sammens-vejst med hinanden til dannelse af mellem folierne 5 indesluttede fryselommer, som står i strømningsmæssig forbindelse med hinanden og med et ved svejseforbindelser i posens topparti afgrænset indløb i en hals, der efter posens fyldning med væske kan lukkes tæt.The invention relates to a disposable bag for use in freezing molds, in particular so-called ice cubes, and consisting of two plastic sheets, which are locally welded together to form freezing pockets enclosed between the sheets 5, which are in flowing relationship with each other and with a welded joint. in the top portion of the bag delimited inlet into a neck which, after filling the bag with liquid, can be closed tightly.

Der kendes sådanne fryseformposer, ved hvilke 10 lukningen foregår ved, at indløbshalsen efter fyldningen af posen bindes i en stram knude. Dette forudsætter dog, at halsen har en større længde end ellers nødvendigt, hvilket medfører et ikke ubetydeligt spild af det relativt dyre posemateriale.Such freezing mold bags are known in which the closure takes place in that the inlet neck, after filling the bag, is tied into a tight knot. However, this assumes that the neck has a longer length than otherwise necessary, which results in a not insignificant waste of the relatively expensive bag material.

15 Dette spild kan undgås ved stram ombinding af halsen med en tråd eller klemme, men hertil kræves altså for hver pose en løsdel, som i givet fald bør leveres sammen med poserne og derved fordyrer disses produktion og navnlig deres emballering i en salgspakning.15 This waste can be avoided by tightly tying the neck with a thread or clamp, but for this a bag is required for each bag, which should, if necessary, be supplied with the bags, thereby increasing their production and, in particular, their packaging in a sales package.

20 En anden kendt mulighed for at undgå overlængder er at lade halsen være sammenhængende med posens to øvre hjørnefelter og at friskære disse fra selve poselegemet, så at de danner en art vinger på siderne af halsen og kan sammenbindes i en knude eller sløjfe under sammen-25 snøring af selve halsen. Denne sammensnøring bør være meget stram for at resultere i den fornødne tæthed, og i praksis kan det ikke undgås, at deformationerne fra sammensnøringen forplanter sig lidt nedad i posen og indvirker uheldigt på faconen af dennes øverste fryselom-30 mer.Another known option to avoid overlengths is to leave the neck contiguous with the two upper corner corners of the bag and cut them off from the bag body itself so that they form a species of wings on the sides of the neck and can be tied together in a knot or loop underneath. 25 lacing of the neck itself. This constriction should be very tight to result in the necessary tightness, and in practice it cannot be avoided that the deformations from the constriction propagate slightly downward in the bag and adversely affect the shape of its upper freezer compartment.

Fra disse kendte udførelser adskiller engangspo-sen ifølge opfindelsen sig ved, at indløbshalsen er indrettet til at lukkes ved fast sammenrulning og sammenbukning samt påfølgende fiksering ved indstikning i et 35 hul dannet i et posehjørnefelt, som er sammenhængende 2 151525 med halsen og selve poselegemet ved svækkelseslinler på en sådan måde, at hjørnefeltet efter oprivning af svækkelseslinierne kan foldes skråt nedad og indad over poselegemet.From these known embodiments, the disposable bag according to the invention differs in that the inlet neck is arranged to be closed by fixed rolling and folding and subsequent fixing by insertion into a hole formed in a bag corner field which is contiguous with the neck and the bag body at weakening lines in such a way that, after tearing the lines of weakening, the corner field can be folded downwards and inwards over the bag body.

5 Ej heller i dette tilfælde kræves der nogen over længde af halsen og dermed af hele posen, idet selv en kort hals kan lukkes tæt ved sammenrulning eller sammensnoning og tvasrbukning. Problemet er at få fikseret den således lukkede hals på en enkel måde, og uden at om-10 kostningerne ved posernes fremstilling, emballering og forsendelse forøges, men hertil tjener det omtalte indstikningshul, som ikke behøver at medføre nogen fordyrelse. En yderligere fordel er, at poselukningen kan foregå under en minimal deformation af fryselommerne i 15 den øverste del af selve poselegemet.5 Neither in this case is it required anyone over the length of the neck and thus of the entire bag, as even a short neck can be closed tightly by rolling or twisting and twisting. The problem is to get the neck thus closed in a simple manner and without increasing the costs of bag making, packaging and shipping, but for this purpose, the said insertion hole serves, which does not have to cause any costing. A further advantage is that the bag closure can take place during a minimal deformation of the freezer pockets in the upper part of the bag body itself.

En udførelsesform for engangsposen ifølge opfindelsen er illustreret på tegningen, der viser den øvre del af en fryseformpose til pudeformede isterninger.An embodiment of the disposable bag according to the invention is illustrated in the drawing which shows the upper part of a freezer bag for cushion shaped ice cubes.

Den viste pose består på ordinær måde af to 20 hinanden dækkende, glasklare, rektangulære stykker plastfolie, der er sammensvejst med hinanden i de ved punktering fremhævede områder, så at der er dannet et antal fryselommer 1 og et indløb 2, der til siderne er afgrænset mellem to i posens højderetning liggende 25 svejsesømme 3.The pouch shown in the ordinary way consists of two 20-piece, glass-clear, rectangular pieces of plastic foil welded together in the areas highlighted by puncture, so that a number of freezer pockets 1 and an inlet 2 are formed, which are bounded to the sides. between two 25 weld seams in the height of the bag 3.

Parallelt med svejsesømmene 3 har de to folier et par svækkelseslinier 4 og 4', hvorved selve halspartiet 5 med indløbet 2 kan rives fri af posetoppens to hjørnefelter 6 og 6', af hvilke det ene har 30 et udstanset cirkulært hul 7 i en forstærkende ringsvejsning 8 nær ved posens hjørne. Hjørnefelterne 6 og 6' er yderligere adskilt delvis fra selve poselegemet ved et par svækkelseslinier 9 og 9', af hvilke den sidste sammen med svækkelseslinien 4' muliggør en 35 fuldstændig afrivning af hjørnefeltet 6', medens hjør-Parallel to the weld seams 3, the two sheets have a pair of weakening lines 4 and 4 ', whereby the neck portion 5 with the inlet 2 can be torn free of the two corner panels 6 and 6' of the bag top, one of which has a punched circular hole 7 in a reinforcing ring weld. 8 near the corner of the bag. The corner panels 6 and 6 'are further separated in part from the bag body itself by a pair of weakening lines 9 and 9', the latter together with the weakening line 4 'allowing a complete tearing of the corner panel 6' while

The nip field 6 after tearing along lines 4 and 9 can be inclined downwardly so that the hole 7 is given the location indicated by a dashed line. After the bag has been filled with water or another liquid to be frozen to form a plurality of cubes which can be easily broken apart, the inlet 2 must be closed tightly, which is done by rolling or collapsing and folding the neck portion 5, after which it is fixed by inserting into the hole 7 in its punctured position. Should the corner field 6 have been eradicated completely free, the closure can be done in quite the same way, since the corner field is then attached to the neck as a loose part. The folding of the neck portion after its collapse or twisting serves to provide extra security for the tightness, but of course the folding can also be done prior to the rolling or twisting of the neck. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
