Asklock av kartong. Cardboard ashtray.

Foreliggande uppfinning avser ett asklack -ay kartong. Sadana lock forekomma bland annat for askar i form av skokartonger, som ut- görsarskilt viktigt anvandoingsomrade I or uppfinningen. Orn en skokartong skall avlagsnas ur en trave eller packat f5rvaringsfack, brukar namligen expediten trada in findbrarna innanf8r lockets framre kortsida och yid denna draga ut kartongen ur traven resp, facket. Da mhste locket yara av sadan beskaffenhet, att namnda kortsida latt kan bojas ut, och likval Mr ingen locksida brista yid den ganska store pakanning, for vilken den utslittes. Utgb.ende friin det kanda faktum, att lockets kortsida blir starkast, om materialfibrerna stracka sig i dess langdriktning, her det varit brukligt att tilliimpa denim fiberriktning. Tydligen komma emellertid Angransande langsidors fibrer att stracka sig dessa sidors tvarriktning, vadar deras kant kan brista 1 narheten ay lockhornen. Dessutom her det i praktiken visat sig, att kortsidornas fria kant latt brister, liven om fibrerna ga i kortsidans langdriktning, och hartill bidrager den omstandigheten, att denna fiberriktning, sum kant ar, gar locksidan styvare an on' fibrerna gh i tvarriktningen. Man har tidigare forsokt eliminera risken for bristning genom dubbelvikning av lockets fria kant till att bilda en fals, men denna jamforelseyis dyrbara atgard motsvaras icke av Rad sakerhet mot bristning yid lockhornens kant, dar materialet deformerats kraftigt genom vikning i tvh mot varandra transversella riktningar. Dessutom forstyvas locksidan alltfor mycket av falsen. Man har till slut sokt losa problemet genom att forse skokartongen tried en saxskild draganordning, men detta innebar specialutforanden, som kunna Oka tillyerkningskostnaderna far mycket. Genom foreliggande uppfinning uppfyllas emellertid fordringarna pa locksidans bojlighet och hallfasthet tillfredsstallande, och detta utan namnvard okning av tillverkningskostnaderna. The present invention relates to an ashtray -ay carton. Such lids occur, among other things, for boxes in the form of shoe boxes, which constitute a particularly important area of use in the invention. If a shoe box is to be removed from a stack or packed in a storage compartment, the clerk usually inserts the finders inside the front short side of the lid and pulls the carton out of the stack or compartment. Then the lid must be of such a nature that the said short side can be easily bent out, and likewise no lid side bursts yid the rather large package for which it was worn out. Based on the well-known fact that the short side of the lid becomes strongest, if the material fibers stretch in its longitudinal direction, here it has been customary to apply the denim fiber direction. Apparently, however, the fibers of adjacent longitudinal sides will extend in the transverse direction of these sides, wading their edge may rupture near the lid horns. In addition, it has been found in practice that the free edge of the short sides is slightly broken, the life of the fibers going in the longitudinal direction of the short side, and the fact that this fiber direction, sum edge, makes the lid side stiffer than the fibers in the transverse direction contributes to this. Attempts have been made in the past to eliminate the risk of rupture by double-folding the free edge of the lid to form a seam, but this comparable action does not correspond to Rad security against rupture at the edge of the lid horn, where the material is strongly deformed by folding in transverse directions. In addition, the lid side is stiffened too much by the seam. In the end, an attempt was made to solve the problem by forcing the shoe box into a scissor-separate pulling device, but this meant special designs, which could increase the cost of attachment a lot. By means of the present invention, however, the requirements for the flexibility and half-strength of the lid side are met satisfactorily, and this without a significant increase in the manufacturing costs.

Enligt uppfinningen ãr asklocket salunda .sh utbildat, att ett invandigt pa en kortsida av locket fastklistrat forstarkningsband av papper med sina fibrer riktade langs denna kortsida och korsande kartongfibrerna strac ker sig kant i kant med lockets fria kant Over kortsidans hela langd och runt angransande lockhorn och tangs hela denna kortsida är belaget pf nagot avstand frail kortsidans vikningskant. Utgaende frhn den kanda omstandigheten, att pepper har sin storsta tanjbarhet i fibrernas tvarriktning, stracka sig kartongfibrerna salunda i locksidans tvarriktning. Den .darigenom naturligtvis minskade hallfastheten motyerkas medelst det pa sarskin sat anordnade forstarkningsbandet. Ehuru forstarkningsbandet Or mycket tunt, sh att det endast obetydligt minskar locksidans bOjlighet, 5kar det namligen likval locksidans seghet i hog grad ph grund av att (less fibrer korsa kartongfibrerna. Bandet skyddar lockkanten oyerallt, dar bristning annars kan befaras. Nagra brottanvisrtingar ph grund av lokala forstarkningar av kortsidekanten ooh angransande hornpartier fiirekomma shlunda icke. Forstarkning vid locksidans vikningskant undvikes daremot, ty dar riskeras ingen bristning, och det Or onskvart att locksidan blir sh tanjbar och bojlig som mojligt innanfor den fria lockkanten. According to the invention, the ash lid salunda .sh is formed, that an internal reinforcing strip of paper adhered to a short side of the lid with its fibers directed along this short side and the intersecting cardboard fibers extend edge to edge with the free edge of the lid over the entire length and around adjacent lid horns and the entire length of this short side is coated at some distance from the folding edge of the short side. Based on the well-known fact that pepper has its greatest extensibility in the transverse direction of the fibers, the cardboard fibers thus extend in the transverse direction of the lid side. This, of course, reduces the half-strength by means of the reinforcing band arranged on the skin. Although the reinforcing tape is very thin, because it only slightly reduces the flexibility of the lid side, it also increases the toughness of the lid side to a high degree due to the fact that (less fibers cross the cardboard fibers. The belt protects the lid edge everywhere, otherwise rupture can be feared. local reinforcements of the short side edge and adjacent horn portions do not occur, however, reinforcement at the folding edge of the lid side is avoided, as there is no risk of rupture, and it is desirable that the lid side be as stretchable and flexible as possible within the free lid edge.

Uppfinningsiden kan ytterligare fullfoljas, om fran kortsidan utgaende, vid lockhornen omvikta andflikar Oro fastade vid lockets langsidor, vilkas fria kant slutar pa nagot aystAnd fran lockhornen. Delta är namligen fordelaktigt sa till vida, att lockhornen kunna sammandragas och avrundas nagot, vilket underlattar mellanliggande locksidas (kortsidans) utb5jning, men genom denna gard minskas hallfastheten. Enligt uppfinningen är darfor yid denna anordning forstarkningsbandet kant i kant med lockets fria kant Oven fastklistrat vid andflikarna och stracker sig fram till och Oven nagot uttiled langsidornas fria kant. The side of the invention can be further completed, if from the short side extending, at the lid horns folded duck flaps Oro attached to the long sides of the lid, the free edge of which ends at some distance east of the lid horns. Namely, the delta is advantageous to the extent that the lid horns can be contracted and rounded somewhat, which facilitates the bending of the intermediate lid side (short side), but through this guard the half-strength is reduced. According to the invention, therefore, in this device the reinforcing band is edge to edge with the free edge of the lid. The oven is glued to the duck flaps and extends up to and above the free edge of the long sides.

Bifogade ritning askadliggiir uppfinningen. genom ett utforingsexempel. Fig. 1 visar perspektiviskt nagra i en trave uppstallda skokartonger med oforstarkta lock. Fig. 2 visar ett utstansat, enligt uppfinningen forstarkt lockamne. Fig. 3 visar i perspektiy det forstarkta locket inifran. The accompanying drawing illustrates the invention. through an embodiment. Fig. 1 shows a perspective view of some shoe boxes with unreinforced lids arranged in a stack. Fig. 2 shows a punched-out, according to the invention pre-reinforced lid blank. Fig. 3 shows in perspective the reinforced lid from the inside.

Enligt fig. 1 skall ph brukligt salt en skokartong dragas at ur den tatt packade tra- 2— — yen, i det att handen trades in under den framre, korta locksidan 1, som skall formed-la dragverkan pa den eventuellt tamligen hart i traven fastsittande kartongen. Da bojes locksidan 1 ut och kan det intraffa att locket spricker, t. ex. vid 2, eller ocksa flakes det enligt fig. 1 upp vid hornkanterna 3. According to Fig. 1, as usual, a shoe box is to be pulled from the taken-packed tray, in that the hand is pulled in under the front, short lid side 1, which is to form a traction effect on the possibly rather hard in the stack. stuck cardboard. Then the lid side 1 is bent out and it can happen that the lid cracks, e.g. at 2, or also flakes it according to Fig. 1 up at the horn edges 3.

Det i fig. 2 visade lockamnets fibrer stracka sig, som antydes med brutna linjer, i det avlanga amnets langdriktning. Detta innebiir, att de stracka sig tvars over de flikar 1, som skola bilda lockets kortsidor, Tailor den ovan angivna och i fig. 1 askadliggjorda olagenheten skulle uppsta, am icke nagon forebyggande atgard vidtages. Enligt fig. 2 är emellerlid ett pappersband 5 paklistrat flikarna 1 och dessas andflikar 4. Bandet 5, vilkets fibrer stracka sig i dess langdriktning, Egger kant i kant med den fria kanten 6 av fliken 1 och andflikarna 4, men pa nagot avstand Iran vikningslinjen 10. Mellan langsideflikarna 7 och andflikarna finnas triangelformade urtagningar 8. Det salunda bildade lockamnets kortsideflikar 1 och dess langsideflikar 7 vikas, sã att de bli kantstallda, varvid bandet 5 bildar en inre skoning It locksidorna 1 och andflikarna 4 kant i kant med lockets fria kant, men ph nagot avstand fran vikningskanten 14 vid linjen 10. Andflikarna 4 vikas innanfOr flikarna 7 och fastas yid dessa t. ex. medelst klamrer, varigenom det i fig. 3 visa-de vid kortsidorna 1 forstarkta men likval mycket elastiska locket erhalles. Som framgar av fig. 3 nar langsidornas fria kant 13 icke fram till lockhOrnen 9, utan mellan den sneda kanten 11 och lockhornet finnes ett av bandet 5 forstarkt och tamligen elastiskt par-ti 12. Av fig. 3 framgar awn, att bandet pa' flikarna 4 stracker sig Irani till och nagot utmed langsidornas fria kant 13. The fibers of the lid blank shown in Fig. 2 extend, as indicated by broken lines, in the longitudinal direction of the elongate blank. This means that they extend transversely over the flaps 1, which are to form the short sides of the lid, Tailor the above-mentioned and in Fig. 1 neutralized disorder would arise, if no preventive action is taken. According to Fig. 2, however, a paper tape 5 is glued to the flaps 1 and their duct flaps 4. The ribbon 5, the fibers of which extend in its longitudinal direction, Egger edge to edge with the free edge 6 of the flap 1 and the duck flaps 4, but at some distance Iran the fold line 10. Between the longitudinal flaps 7 and the duck flaps there are triangular recesses 8. The short side flaps 1 of the thus formed lid name and its longitudinal flaps 7 are folded so that they are edge-shaped, the band 5 forming an inner shoe It the lid sides 1 and the duck flaps 4 edge to edge with the free edge of the lid , but ph some distance from the folding edge 14 at the line 10. The duck flaps 4 are folded inside the flaps 7 and fastened yid these e.g. by means of clamps, whereby the reinforced but nevertheless very elastic cover shown in Fig. 3 is obtained at the short sides 1. As can be seen from Fig. 3, the free edge 13 of the longitudinal sides does not reach the lid horn 9, but between the oblique edge 11 and the lid horn there is a reinforced and rather elastic portion 12 of the belt 5. the tabs 4 extend to Irani and slightly along the free edge 13 of the long sides.

Uppfinningens rackvidd skall icke anses vara begransad till den It ritningen visade och I anslutning (Thrall beskrivna utforingsformen, utan denna kan modifieras, utan att uppfinningstanken frangas. Eventuellt kunna andflikarna 4 vara lagda utanpa langsideflikarna 7. Ehuru i praktiken tva varandra motstaende locksidor lampligen bdda tva bora vara utbildade enligt uppfinningen, utesluter detta icke, att uppfinningen aven kan tilllampas vid forstarkning av en enda locksida. The scope of the invention should not be construed as limited to the embodiment shown in the drawing and in connection (Thrall described embodiment, but this can be modified without departing from the spirit of the invention. Possibly the duck flaps 4 may be laid outside the longitudinal flaps 7. Although in practice two opposite lid sides) should be trained according to the invention, this does not exclude that the invention can also be applied when reinforcing a single lid side.
