Den foreliggende opfindelse angår profilerede par af i hinanden indgribende lukkestrimler bestående af et hun!ukkeelement samt et han-lukkeelement, der er udformet til at kunne gå i indgreb med hunlukke-elementet, og som er dannet af en af lukkestrimlerne, som udgøres af 5 en profil del, der har en basisdel med et par adskilte parallelt anbragte væv, der er fastgjort til basisdelen for dannelse af et stort set U-formet tværsnit, hvilke væv ender i kroge, der omfatter krogdele, som vender væk fra hinanden, hvilket hun!ukkeelement er dannet af den anden af lukkestrimlerne, som udgøres af en profil del med en ba-10 sisdel, der har et par adskilte anbragte væv, der er fastgjort til basisdelen for dannelse af et stort set U-formet tværsnit, og som er adskilt for at passere over vævene på hanlukkeelementet, hvilke væv på hun!ukkeelementet ender i kroge, der er udstrakt mod hinanden for at gå i indgreb med krogene på hanlukkeelementet. En lukkebefæstelsesind-15 retning af denne type kendes fra britisk patentskrift nr. 2.017.813.The present invention relates to profiled pairs of interlocking closure strips consisting of a female closure member and a male closure member configured to engage the female closure member formed by one of the closure strips constituted by a profile portion having a base portion with a pair of spaced apart parallel webs attached to the base portion to form a substantially U-shaped cross section, said webs ending in hooks comprising hook sections facing away from each other, which she The yoke element is formed by the second of the closure strips, which is formed by a profile portion having a base portion having a pair of spaced apart webs attached to the base portion to form a substantially U-shaped cross section, which is separated to pass over the tissues of the male closure member, which tissues of the female member end in hooks which are extended toward each other to engage the hooks of the male closure member. A closure fastener of this type is known from British Patent Specification No. 2,017,813.
Profilerede par af lukkestrimler til brug sammen med plastposer skal være relativt lette at åbne og lukke samt tilvejebringe en tilfredsstillende tætning. Imidlertid har det vist sig, at det fra britisk 20 patentskrift nr. 2.017.813 kendte profilerede par af lukkestrimler har en ulempe, idet han- og hunlukkeelementerne har en tendens til at skræve over hinanden med et af hunlukkeelementets væv placeret mellem hanl ukkeel ementets to væv. Der opnås således ikke på sikker måde en tilsigtet tillukning, hvor begge hanlukkeelementets væv placeres mel-25 lem hunlukkeelementets to væv. En sådan ikke-tillukket og skrævende tilstand for han- og hunlukkeelementerne på en plastpose forhindrer lukkeelementernes normale tillukning, hvilket medfører, at posens indhold ikke bliver indeholdt på sikker måde i posen. Følgeligt er det ønskeligt at tilvejebringe en mere sikker styring af det modstillede 30 han- og hunlukkeelement, således at elementerne indgriber gentagne gange i den normalt tillukkede tilstand, og således at elementerne er forhindret i at gå indgreb i den ovenfor omtalte ikke-tillukkede og skrævende tilstand.Profiled pairs of closure strips for use with plastic bags should be relatively easy to open and close as well as provide a satisfactory seal. However, it has been found that the profiled pairs of closure strips known from British Patent No. 2,017,813 have a disadvantage, since the male and female closure members tend to overlap one of the webs of the female closure member located between the two male closure members. tissue. Thus, an intentional closure is not achieved in which both tissues of the male closure member are placed between the two tissues of the female closure member. Such a non-sealed and tapered state of the male and female closure members of a plastic bag prevents the closure members' normal closure, which means that the contents of the bag are not safely contained in the bag. Accordingly, it is desirable to provide a more secure control of the opposing male and female closure member so that the members engage repeatedly in the normally closed condition and so that the members are prevented from engaging in the above-mentioned non-closed and canted condition.
35 Det er således formålet med den foreliggende opfindelse at afhjælpe den ovenfor nævnte ulempe.It is thus the object of the present invention to remedy the disadvantage mentioned above.
Dette formål opfyldes ifølge den foreliggende opfindelse med et profileret par af lukkestrimler af den indledningsvis nævnte type, og somThis object is fulfilled according to the present invention with a profiled pair of closure strips of the type mentioned initially and which

2 er særpræget ved, at krogene på han!ukkeelementet har krogfremspring, der vender mod hinanden.2 is characterized in that the hooks on the male element have hook projections facing each other.
Med et således tilvejebragt profileret par af lukkestrimler vil han-5 lukkeelementet og hunlukkeelementet, selv om de ikke er fuldstændig liniestillet, blive styret til den tilsigtede 1iniesti11ing ved hjælp af krogfremspringene, der er udstrakt mod hinanden fra hankrogdel ene.With such a profiled pair of closure strips, the male closure element and the female closure element, although not completely aligned, will be guided to the intended alignment by means of the hook projections extended towards each other from the male hook members.
Den større grad af sikkerhed for korrekt tillukning af lukkeelementerne opnås således ved, at de to krogfremspring, der vender mod hinan-10 den, reducerer bredden af den tværgående åbning mellem hanlukkeelemen-tets væv i området ved krogene. Herved vil muligheden for den ukorrekte tillukning, hvor et af hunlukkeelementets væv placeres mellem han-1ukkeelementets to væv, være reduceret og derved øges sikkerheden for en korrekt tillukning.Thus, the greater degree of security of proper closure of the closure members is achieved by the two hook projections facing each other reducing the width of the transverse opening between the male closure member tissues in the region of the hooks. In this way, the possibility of the incorrect closure, where one of the female closure elements' tissue is placed between the two tissues of the male closure member, is reduced, thereby increasing the security of a correct closure.

3 Således som vist i fig. 2 omfatter det profilerede par af lukkestrimler 14 en hanprofil del 18", der er forbundet med en flangedel 19 og indbefatter en basisdel 20, et par adskilte parallelt anbragte væv 21, der strækker sig i en stort set vinkelret retning fra basisdelen 20, 5 og hankroge 22', der er udstrakt fra vævene 21 og vender væk fra hinanden. En hunprofildel 24 for et hunlukkeelement (fig. 3) er forbundet med en flangedel 25 og indbefatter en basisdel 26, et par adskilte, parallelt anbragte væv 27, der er udstrakt i en stort set vinkelret retning i forhold til basisdelen 26 samt hunkroge 28, der er udstrakt 10 fra vævene 27, og som vender mod hinanden. Hver af hunkrogene har afrundede krogflader 29 og 29', der fungerer for at styre krogdelene for tillukning sammen med hankrogene fra et afpasset hanlukkeelement. Pro-fi Idel ene 18' og 24 kan være dannet separat og derefter forbundet med en film, som danner sidevæggene 13 eller de kan være dannet integralt 15 med sidevæggene 13, således som vist i fig. 1.3 As shown in FIG. 2, the profiled pair of closure strips 14 comprises a male profile portion 18 "which is connected to a flange portion 19 and includes a base portion 20, a pair of spaced apart parallel webs 21 extending in a substantially perpendicular direction from the base portion 20, 5, and male hooks 22 'extending from the webs 21 and facing away from each other A female profile portion 24 of a female closure member (FIG. 3) is connected to a flange portion 25 and includes a base portion 26, a pair of spaced apart parallel webs 27 extended in a substantially perpendicular direction with respect to the base portion 26 and female hooks 28 extending 10 from the webs 27 facing each other. Each of the female hooks has rounded hook faces 29 and 29 'which act to guide the hook portions for closure together. The parts 18 'and 24 may be formed separately and then connected to a film forming the side walls 13 or they may be integrally formed with the side walls 13, such as shown in FIG. First
Ifølge den foreliggende opfindelse, når ydersiderne 32 af hankrogene 22' er kontureret, således som vist i fig. 2-5, har det vist sig, at en sådan konstruktion vil forhindre dårlig 1 i ni esti 1 ling og tilveje-20 bringe en sikker styring af de afpassede lukkeelementer og elementerne vil indgribe let og nøjagtigt i den ønskede tillukkede stilling.According to the present invention, when the outer surfaces 32 of the male hooks 22 'are contoured, as shown in FIG. 2-5, it has been found that such a construction will prevent poor 1 in nine positioning and provide a safe control of the fitted closure elements and the elements will engage easily and accurately in the desired closed position.
I fig. 2 er hanprofildelen 18' ifølge den foreliggende opfindelse vist i detaljer, hvorhos krogfremspringene 31 på krogene 22' kan ses ud-25 strakt fra de stiplede linier 23", som er vist deri, for således at danne en reduceret spalte mellem krogdelene 22', for således fysisk at forhindre den skrævning for hanlukkeelementet og hunlukkeelementet. Følgelig er den ønskede hindring for den skrævende stilling, som kan optræde mellem hanlukkeelementet og hunlukkeelementet, opnået og li-30 geledes er den anden ønskede egenskab ved tillukning muliggjort ved at tilvejebringe en styre virkning for hunlukkeelementets krogflader, der kan glide langs ydersiderne 32 af hanlukkeelementets kroge 22'. En sådan styring er medvirkende til at lede han- og hunlukkeelementerne ind i deres rigtige tillukkede stilling. Således som det vil indses af 35 fagfolk på området, kan krogfremspringene 31 have en hvilken som helst passende længde, for således i alt væsentligt at lukke spalten eller mellemrummet mellem sig og udelukke indtrængning deri for hunlukkeelementets krog- og vævdele og derved i realiteten sikre tillukning og udelukkelse af muligheden for skrævning for han- og hunlukkeelementer-In FIG. 2, the male profile portion 18 'of the present invention is shown in detail whereby the hook projections 31 of the hooks 22' can be seen extended from the dotted lines 23 "shown therein, so as to form a reduced gap between the hook portions 22 ', Accordingly, the desired obstruction to the cantilever position which may occur between the male closure member and the female closure member is achieved and likewise the other desired closure property is made possible by providing a controlling effect. for the hooks of the female closure member, which may slide along the outer sides 32 of the hooks 22 'of the male closure member, such a guide contributes to guide the male and female closure members into their proper closed position, as will be appreciated by 35 professionals in the art, the hook projections 31 may have any suitable length so as to substantially close the gap or gap between them and preclude penetration therein for the hook and woven parts of the female closure member, thereby effectively securing and eliminating the possibility of scraping for male and female closure members-

Overvejelser med hensyn til fremstillingen kan begrænse den udstrækning, hvortil krogfremspringene 31 er bragt imod hinanden og derved 5 reducere styreeffekten mellem hanlukkeelementet ifølge nævnte opfindelse og det indgribende hunlukkeelement ifølge den foreliggende opfindelse. Tilfredsstillende resultater er blevet opnået, når krogfremspringene 31 har længder, der, på en skala som er afpasset i forhold til den tillukkede højde og tillukkede bredde for den indgribende be-10 fæstel seslukkeindretning, er mellem 0,13 mm og 0,20 mm, således som målt mellem de stiplede linier 33, der er vist i fig. 2. Imidlertid foretrækkes det, at krogfremspringene 31 har længder, der, på en skala som er afpasset i forhold til den tillukkede højde og tillukkede bredde for de profilerede par af lukkestrimler, er mellem 0,13 mm og 0,51 15 mm, da sådanne længder tilvejebringer de førnævnte ønskede egenskaber for profilerede par af lukkestrimler.Manufacturing considerations may limit the extent to which hook projections 31 are brought against each other, thereby reducing the control power between the male closure member of the present invention and the engaging female closure member of the present invention. Satisfactory results have been obtained when the hook projections 31 have lengths which, on a scale adapted to the enclosed height and enclosed width of the interlocking fastening closure device, are between 0.13 mm and 0.20 mm. as measured between the dotted lines 33 shown in FIG. 2. However, it is preferred that the hook projections 31 have lengths which, on a scale adapted to the closed height and width of the profiled pairs of closure strips, are between 0.13 mm and 0.51 15 mm, since such lengths provide the aforementioned desired properties for profiled pairs of closure strips.
Ifølge en foretrukket udførelsesform for den foreliggende opfindelse har visse parter af hanlukkeelementets kroge 22' ifølge den forelig-20 gende opfindelse længder, som, på en skala der er afpasset i forhold til den tillukkede højde og tillukkede bredde for det profilerede par af lukkestrimler, er mellem 0,13 mm og 0,25 mm, således som målt mellem de stiplede linier 34, som er vist i fig. 2.According to a preferred embodiment of the present invention, certain portions of the male closure element hooks 22 'of the present invention have lengths which, on a scale adapted to the enclosed height and width of the profiled pair of closure strips, are between 0.13 mm and 0.25 mm, as measured between the dotted lines 34 shown in FIG. 2nd
25 Fig. 3 viser et hanlukkeelement ifølge den foreliggende opfindelse i en dårligt liniestillet stilling i forhold til et hunlukkeelement u-middelbart forud for tillukning dermed. Fra fig. 3 kan det ses, at selv om hanlukkeelementet og hunlukkeelementet er dårligt liniestillet, så vil de blive styret ind i den ønskede tillukkende liniestil-30 ling ved hjælp af krogfremspringene 31, der er udstrakt mod hinanden fra hankrogene 22' for en sluttelig indgribende tillukning.FIG. 3 shows a male closure element of the present invention in a poorly aligned position relative to a female closure element immediately prior to closure thereof. From FIG. 3, it can be seen that although the male closure element and the female closure element are poorly aligned, they will be guided into the desired closure line position by the hook projections 31 extended towards each other from the male hooks 22 'for a final engaging closure.
I fig. 4 kan det ses, at, når hanlukkeelementet ifølge den foreliggende opfindelse er rigtigt liniestillet med en hunlukkeelement umid-35 del bart forud for tillukning, vil dette ikke alene medføre en større tillukningslethed derimellem, men vil også forhindre hanlukkeelementets og hunlukkeelementets bevægelse til en ikke-tillukket skrævende stilling.In FIG. 4, it can be seen that when the male closure element of the present invention is properly aligned with a female closure element immediately prior to closure, this will not only cause greater closure ease therebetween, but will also prevent the movement of the male closure element and the female closure element to a non-closure. closed cramped position.

Et profileret par af lukkestrimler ifølge den foreliggende opfindelse kan være fremstillet med en tillukket højde mellem 1,52 mm og 2,16 mm, fortrinsvis 1,78 mm, og en tilsvarende tillukket bredde mellem 2,41 mm og 3,18 mm, fortrinsvis 2,79 mm.A profiled pair of closure strips of the present invention may be made with a closed height between 1.52 mm and 2.16 mm, preferably 1.78 mm, and a corresponding closed width between 2.41 mm and 3.18 mm, preferably 2.79 mm.
15 Således som anvendt heri vil udtrykket "afpasset" indikere de relative proportioner for lukkestrimlernes lukkeelementer, når han- og hunluk-keelementerne er tillukkede. Når det profilerede par af lukkestrimler ifølge den foreliggende opfindelse har en tillukket højde mellem 1,52 20 mm og 2,16 mm og en tillukket bredde mellem 2,41 mm og 3,18 mm, er længderne mellem hanlukkeelementets kroge mellem 0,13 mm og 0,25 mm, og længderne af hanlukkeelementets krogfremspring er mellem 0,13 mm og 0,51 mm på en skala, der er afpasset i forhold til den tillukkede højde og tillukkede bredde for det profilerede par af lukkestrimler. Når 25 den tillukkede højde og tillukkede bredde for det profilerede par af lukkestrimler ifølge den foreliggende opfindelse enten forøges eller formindskes, skal længderne af hanlukkeelementets kroge og krogfremspring følgelig forøges eller formindskes proportionalt for at opretholde de relative proportioner for lukkeelementerne.As used herein, the term "matched" will indicate the relative proportions of the closure elements of the closure strips when the male and female closure members are closed. When the profiled pair of closure strips of the present invention has a closed height between 1.52 20 mm and 2.16 mm and a closed width between 2.41 mm and 3.18 mm, the lengths between the hooks of the male closure member are between 0.13 mm and 0.25 mm, and the lengths of the hook closure of the male closure member are between 0.13 mm and 0.51 mm on a scale adapted to the closed height and width of the profiled pair of closure strips. Accordingly, when the enclosed height and width of the profiled pair of closure strips of the present invention are either increased or decreased, the lengths of the male closure member hooks and hook projections must be increased or decreased proportionally to maintain relative proportions of the closure members.

En termoelektrisk indretning kan påføres en folie i kon-15 takt med flangedelen for et lukkeelement, eller den termoelektriske indretning kan påføres en folie i kontakt med basisdelen for et lukkeelement, som ikke har nogen flangedele for at frembringe en varmeover-føring gennem folien for derved at danne en smelte ved grænsefladen mellem folien og lukkeelementets flangedel eller basisdel. Ved afkø-20 ling vil grænsefladeområdet forbinde folien og lukkeelementet. Den termoelektriske indretning kan opvarmes ved hjælp af drejeskiver, modstandsopvarmede gi idevirer, vandrende opvarmningsbånd eller lignende. Forbindelsen mellem folien og lukkeelementet kan også tilvejebringes ved anvendelse af varmsmeltelige klæbemidler eller varmluftstråling 25 til grænsefladen eller ultralydsopvarmning eller andre kendte fremgangsmåder. Generelt kan det profilerede par af lukkestrimler og folien være fremstillet af et varmeforsegleligt materiale, således at en beholder kan dannes billigt ved varmeforsegling af de førnævnte komponenter til dannelse af beholderen.In practicing the present invention, the profiled pair of closure strips may be formed integrally with the side walls of a container or connected with a container or foil to be formed into a container using any of many known methods. A thermoelectric device may be applied to a foil in contact with the flange portion of a closure element, or the thermoelectric device may be applied to a foil in contact with the base portion of a closure member which has no flange portions to produce a heat transfer through the foil so as to forming a melt at the interface between the foil and the flange portion or base portion of the closure member.

Desuden er det profilerede par af lukkestrimler vanskeligere at oplukke fra beholdernes inderside end fra beholdernes yderside og tilvejebringer således en mere sikker indeholdelse af varer, som for eksempel levnedsmiddelprodukter. Profildelene af lukkestrimlerne har tilnærmel-5 sesvis ensartet tværsnit. Dette forenkler ikke alene lukkestrimlernes fremstilling, men det bidrager også til lukkestrimlernes fysiske bøjelighed, hvilket er en ønskelig egenskab.In addition, the profiled pair of closure strips is more difficult to open from the inside of the containers than from the outside of the containers, thus providing a more secure containment of goods, such as food products. The profile portions of the closure strips have approximately uniform cross sections. This not only simplifies the manufacture of the closing strips, but it also contributes to the physical flexibility of the closing strips, which is a desirable property.
Det profilerede par af lukkestrimler ifølge den foreliggende opfindel-10 se kan også anvendes som et bøjeligt rør, da det er muligt at tilvejebringe en god forsegling ved de indgribende overflader, og en afdeling, der er tilvejebragt ved hjælp af de tillukkede lukkeelementer, tilvejebringer en passage, som ikke klapper sammen, når det profilerede par af lukkestrimler bøjes moderat.The profiled pair of closure strips of the present invention can also be used as a flexible tube as it is possible to provide good sealing at the engaging surfaces and a compartment provided by the closed closure elements provides a passage that does not collapse when the profiled pair of closure strips bends moderately.

Det profilerede par af lukkestrimler ifølge den foreliggende opfindelse kan fremstilles i et stort antal former for at passe til den tilsigtede anvendelse. Desuden kan han- og hunlukkeelementerne anbringes på modsatte sider af en folie. En sådan udførelsesform vil være egnet 20 til omvikling af en genstand eller en samling af genstande, som for eksempel virer. Generelt skal han- og hunlukkeelementerne på en folie være parallelle med hinanden, men dette vil afhænge af den tilsigtede anvendelse.The profiled pair of closure strips of the present invention can be manufactured in a wide variety of shapes to suit the intended use. In addition, the male and female closure members may be placed on opposite sides of a foil. Such an embodiment will be suitable for wrapping an article or a collection of articles, for example, wires. In general, the male and female closure elements of a foil must be parallel to each other, but this will depend on the intended use.
