Description

Opfindelsen angår tasker, og navnlig indkøbstasker og lignende tasker til transport af købmandsvarer og viktualier.The invention relates to bags, and in particular, shopping bags and similar bags for the transport of groceries and essentials.

Indkøbstasker er nu om stunder gået noget af mode, 5 idet de i stort omfang er blevet erstattet af éngangs-papirposer eller tynde plastposer til indpakning af supermarkedvarer. Tendensen til at købe flere varer på én gang førte til, at de traditionelle, såkaldte indkøbstasker generelt var for små.Shopping bags have now gone out of fashion at times, 5 having been largely replaced by disposable paper bags or thin plastic bags for packaging supermarket goods. The tendency to buy several items at one time led to the traditional so-called shopping bags being generally too small.

10 En indkøbstaske, som er stor nok til at rumme et storindkøb er, hvis den har en traditionel form, ligeledes uhensigtsmæssig stor og pladskrævende at bære i tom tilstand, og til at opmagasinere, når den ikke er i brug.10 A shopping bag large enough to accommodate a large shopping bag, if it has a traditional shape, is also inappropriately large and bulky to carry in its empty state, and to store when not in use.

Masseindkøb indebærer normalt en transport ved vogn 15 enten i bagagerummet eller på sædet af en bil, eller i tilfælde af offentlige trafikmidler på en bagagehylde eller en bagageplads, som ikke findes umiddelbart ved siddepladserne. Supermarked-posér af plast og papir har ikke noget lukke, hvorfor varerne kan falde ud af tasken og ind i bilens baga-20 gerum eller langs bilens gulv, medens der ved offentlig transport ligeledes er fare for rapseri.Bulk purchases usually involve a transport by carriage 15 either in the trunk or on the seat of a car, or in the case of public transport on a luggage rack or a luggage space which is not immediately found at the seating. Supermarket bags made of plastic and paper have no closure, so the goods can fall out of the bag and into the car's luggage compartment or along the floor of the car, while there is also a risk of rape on public transport.

Da endvidere frosne levnedsmidler udgør en væsentlig post ved nutidens indkøb, er det ønskeligt, at taskerne ikke alene skal kunne lukkes, men også låses for bedre at 25 forhindre en optøning af varerne på vejen hjem. En sådan taske er genstand for tysk patentskrift nr. DE-A1-3.539.626, hvis indhold danner grundlag for indledningen til patentkrav 1.Furthermore, since frozen foods constitute an essential item in today's procurement, it is desirable that the bags should not only be able to be closed but also locked to better prevent thawing of the goods on the way home. Such a bag is the subject of German patent specification DE-A1-3,539,626, the contents of which form the basis for the introduction to claim 1.

Formålet med opfindelsen er at tilvejebringe en ind-30 købstaske, der ikke er behæftet med ulemperne ved supermarkedernes éngangs-papir- eller plastposer, eller ved de traditionelle, mere modstandsdygtige indkøbstasker.The object of the invention is to provide a shopping bag which does not suffer from the disadvantages of the disposable paper or plastic bags of the supermarkets, or the traditional, more resilient shopping bags.

Opfindelsen angår en isolerende taske til transport af frosne eller kølede levnedsmidler, med forvæg og bagvæg 35 og en åbning til taskens indre imellem forvæggens og bagvæggens øverste rande, hvilken åbning er lukkelig ved, at rande- DK 169302 B1 2 nes inderflader trykkes mod hinanden, og til at lukke op ved at randene trækkes fra hinanden, hvilken taske endvidere har en rektangulær bundvæg og trekantede sidevægge, hvorhos tasken er foldelig ved forbindelserne mellem de vægge, af 5 hvilke den er dannet, og opfindelsen er ejendommelig ved, at bundvæggen har en foldelinie forløbende centralt i bundvæggen og parallelt med forvæggens og bagvæggens nederste kanter, og at sidevæggene har foldelinier anbragt centralt i sidevæggene og forløbende nedefter fra åbningen til et 10 sammentræf med bundvæggens foldelinie ved modsatte ender af denne, og at foldelinierne i bundvæggen og sidevæggene er dannet af svejsesømme og for-, bag-, bund- og sidevæggene er dannet af indre og ydre lag og et mellemliggende termisk isolerende materiale.BACKGROUND OF THE INVENTION The invention relates to an insulating bag for transporting frozen or refrigerated foodstuffs, having a front wall and a back wall 35 and an opening to the interior of the bag between the upper edges of the front wall and the rear wall, which opening is closed by pressing the inner surfaces of the edge edges together, and to open by pulling the edges apart, the bag further having a rectangular bottom wall and triangular side walls, the bag being foldable by the connections between the walls of which it is formed, and the invention being characterized in that the bottom wall has a fold line extending centrally in the bottom wall and parallel to the lower edges of the front wall and rear wall, and the side walls having fold lines arranged centrally in the side walls and extending downwardly from the opening to coincide with the bottom wall fold line at opposite ends thereof, and the fold lines being in the bottom wall and bottom walls of the weld seams and the front, back, bottom and side walls are formed by i lower and outer layers and an intermediate thermal insulating material.

15 Som angivet i krav 2 kan tasken foroven have et bære håndtag, der som angivet i krav 3 består af med åbninger udstyrede flige,· som rager frem udadtil fra forvæggens og bagvæggens øverste rande.As stated in claim 2, the bag at the top may have a carrying handle which, as stated in claim 3, consists of openings equipped with openings, which protrude outwards from the upper edge of the front wall and the rear wall.

Som angivet i krav 4 kan indersiderne af forvæggene 20 og bagvæggens øverste rande kan bære længder af fastholdelsesbånd, som ved sammentrykning mod hinanden kan bringes til at hænge sammen. Sådanne bånd kan som angivet i krav 5 være af den slags, der på en side har overskårne luvløkker af monofilamenter, som danner kroge, der er indrettet til 25 indgrebsforbindelse med uopskårne fiberløkker på fastholdelsesbåndet på den anden side. Forbindelsesbånd af denne art er sommetider kendt som "Velcro" .As set forth in claim 4, the insides of the front walls 20 and the upper edges of the back wall can carry lengths of retaining straps which, when compressed against each other, can be brought together. Such belts may, as set forth in claim 5, be of the type having on one side carved loop loops of monofilaments forming hooks adapted to engage with uncut fiber loops on the retaining band on the other side. Connectors of this kind are sometimes known as "Velcro".

Endvidere kan tasken som angivet i krav 6 ved hver af åbningens ender have mekaniske fastholdelsesorganer, der 30 som angivet i krav 7 kan bestå af snaplåse såsom trykknaplåse.Furthermore, the bag as claimed in claim 6 at each end of the opening may have mechanical retaining means which, as stated in claim 7, may consist of snap locks such as snap fasteners.

En udførelsesform for en taske ifølge opfindelsen skal i det følgende beskrives nærmere under henvisning til tegningen, på hvilken 35 fig. 1 viser en skrå afbildning af tasken i brugsstil ling, og med nogle dele fjernet, og 3 DK 169302 B1 fig. 2 i skrå afbildning i sammenfoldet opmagasineringsstilling.An embodiment of a bag according to the invention will now be described in more detail with reference to the drawing, in which FIG. 1 shows an oblique view of the bag in service position, with some parts removed, and 3 FIG. 169302 B1 fig. 2 in an oblique view in the collapsed storage position.

Den viste taske 10 har en forvæg 11, en bagvæg 12, en rektangulær bundvæg 13, og over for hinanden beliggende 5 trekantede sidevægge 14 og 15.The shown case 10 has a front wall 11, a back wall 12, a rectangular bottom wall 13, and opposite one another 5 triangular side walls 14 and 15.

Alle disse vægge er termisk isolerende og har indre og ydre lag 16 og 17 af et formstof-plademateriale, som omslutter et mellemliggende lag af termisk isolerende materiale 18, eksempelvis et flor af polyesterfibre.All of these walls are thermally insulating and have inner and outer layers 16 and 17 of a plastic sheet material which encloses an intermediate layer of thermally insulating material 18, for example, a web of polyester fibers.

10 Taskens vægge er indbyrdes forbundet ved deres kanter ved hjælp af svejsesømme, som danner foldelinier. Yderligere svejsesømme danner en foldelinie 19, der er placeret centralt i bundvæggen 13 og parallelt med forvæggens og bagvæggens nederste rande, og foldelinier 20 og 21, der er placeret 15 centralt i sidevæggene og strækker sig fra taskens åbning nedefter til at møde bundvæggens foldelinie 19 ved modsatte ender af denne, således at tasken kan foldes fladt som vist i fig. 2.10 The walls of the bag are interconnected at their edges by weld seams which form fold lines. Further weld seams form a fold line 19 located centrally in the bottom wall 13 and parallel to the lower edges of the front wall and back wall, and fold lines 20 and 21 located 15 centrally in the side walls extending from the bag opening downward to meet the bottom wall fold line 19 at opposite ends thereof so that the bag can be folded flat as shown in FIG. 2nd

Den mellem forvæggen 11's og bagvæggen 12's øverste 20 rande dannede åbning af tasken kan lukkes ved, at randenes indersider presses mod hinanden, og åbnes ved, at randene trækkes fra hinanden. Randenes inderflade er udstyret med fastholdelsesbånd 22 og 23 af tekstil, der udviser henholdsvis overskårne luvløkker af monofilamenter, og uopskårne 25 fiberløkker. Egnede fastholdelsesbånd er markedsført under navnet Velcro .The opening of the bag formed between the upper 20 edges of the front wall 11 and the rear wall 12 can be closed by pressing the inside of the edges against each other and opening by pulling the edges apart. The inner surface of the edges is provided with retaining strips 22 and 23 of textile which show, respectively, carved loop loops of monofilaments and uncut 25 fiber loops. Suitable restraint straps are marketed under the name Velcro.

Yderligere mekaniske fastholdelsesorganer i form af trykknapper 27 findes anbragt ved hver ende af åbningen.Additional mechanical retaining means in the form of pushbuttons 27 are provided at each end of the aperture.

Alternativt kan randene bære fastholdelsesbånd af 30 formstof, som danner ribber og riller eller lignende dele, som kan gå i indgreb med hinanden.Alternatively, the edges may carry retaining bands of 30 resins forming ribs and grooves or similar parts which may engage one another.

Tasken har et håndgreb bestående af flige 24 og 25, der rager ud fra forvæggens og bagvæggens øverste rande. Fligene 24 og 25 har åbninger 26, som fingrene af en hånd 35 kan gribe ind i.The bag has a handle consisting of tabs 24 and 25 protruding from the upper edges of the front wall and the back wall. The tabs 24 and 25 have openings 26 which the fingers of a hand 35 can engage.
