Definitions

• the invention relates to a carrying handle for packages, e.g. for bags of plastic and paper, to attach to these or integrated in the package itself, so that it becomes more comfortable to carry as well as obtains a lockable closing mechanism, and furthermore a new type of carrying package as nearer specified especially in the introduction to claim 1.
• handles for packages are known.
• the handles e.g. can be integrated in the material of the bag as two prolonged, for four fingers adapted punched holes at the middle of the upper edge of the bag.
• this e.g. can be folded down to double thickness, or extra plastic foil can be added around the two holes before they are punched.
• loose carrying handles to be placed on the package which usually consists of two strings of the same or a stronger material than that of the package, which are attached at the upper edge in approximately a mutual distance of the broadness of a hand.
• a more advanced embodiment of a carrying handle for plastic bags which at the same time serves as a closure for bags, is invented of Leon Kerr Laguerre and known e.g. from Danish Patent No. 101895. It consists of two plastic injection molded parts for placing facing each other at the upper edge of the bag. Each part has downwards in the most or in the total of the broadness of the bag a slim tape glued on the inside of the bag, while each part upwards forms half a handle. By means of holes in one part and corresponding taps in the other part the two parts after filling of the bag can be squeezed together to a carrying handle, which also serves as a stable closing mechanism of the bag.
• Windm ⁇ ller & Holscher thus in DE 1536366 shows a handle for attaching to a package
• Gatward shows in GB 797,755 an in a carrying bag integrated handle with a carving designed as a handle with regions preserved of the cut-out material.
• the cut out is attached to the top and will in a joined bending of the preserved regions form a carrying handle.
• a stronger as well as a more comfortable rounded carrying handle is obtained, which will not cut too much into the fingers.
• the purpose of the carrying handle according to the invention therefore is to correct the above-mentioned disadvantages by the hitherto known carrying handles, while at the same time the advantages not only are preserved but even increased, plus to create a better type of carrying package.
• This purpose is especially obtained by the carrying handle according to the invention is formed as indicated in the characterizing part of claim 1.
• the carrying handle according to the invention being embodied as a relatively thin foil of plastic or cardboard, which is attached to the package, or of the material of the package alone, the carrying handle will be simple and cheap to produce and it will require a minimum of space as it in its simplest shape as carrying handles integrated in existing bags only have to be cut out of the material of the package itself, but in a slightly different design, even without the partly punched-out material needs to be removed.
• the handle can possibly even, as it already is common, be reinforced by an extra layer of down-bended or on-glued plastic foil just around the cut out region. This implies the great advantage that these integrated carrying handles can be produced on already existing machinery with few and small changes of the tool. This enables a quick, simple and cheap change to production of plastic bags according to the invention, which in connection with an only slightly higher price than the known plastic bags will be able to facilitate the introduction of the new carrying handles.
• the carrying handle and the carrying package according to the invention will obtain this by just a small change of the punched out regions, so that an extension and a corresponding carving or slit arises.
• this slit the extension from the bent region easily can be squeezed into and be locked tightly, which will increase the value of the carrying handle as a closing mechanism as well as improve its strength.
• Another design of the carrying handle according to the invention specially concerns paper bags, which are closed by being folded as e.g. bakery bags. It only needs an extra bending of the bag plus an supplementary punching-out in the bag material itself, preferably on the top of and of the same design as the first, but the wrong way around in relation to this.
• the bag possibly can be reinforced by an extra piece of on-glued material on one of its sides. Thereby a handle is obtained with several times the original thickness of the bag material, which enables to use bags of lesser strong paper.
• This system also advantageously can be adjusted to and incorporated in plastic bags.
• Carrying handles according to the invention can be formed to attachment to a prolonging of the package as well.
• the carrying handle then can be cut out in a special shape from a relatively thin and stiff foil of polyethylene or polypropylene, or from laminates of these materials, while there for bags of paper can be used carrying handles of paper or cardboard.
• its material e.g. can be a clear and stiff foil of polypropylene or a finer type of cardboard.
• fig. 1 a known carrying handle for attaching to the package seen from in front
• fig. 2 the same seen in a cross section squeezed together and in a bent state
• fig. 3 a cross section of a carrying handle with several folding lines
• fig. 4 a carrying handle according to the invention seen from in front
• fig. 5 the same seen from the back side in a closed and locked state
• fig. 6 the same seen in a cross section
• fig. 7 a shape of an in a carrying bag integrated handle according to the invention
• fig. 8 another shape of an integrated carrying handle according to the invention
• fig. 9 a connected set of carrying handles according to the invention
• fig. 10 a carrying package with a handle according to the invention seen from above and open.
• Fig. 1 shows a known version of an attached carrying handle seen from in front, where a package 1, e.g. a bag of plastic or paper, at the top edge has two opposite each other placed and here identically shaped parts 2 and T of said handle, e.g. punched out from a foil of polyethylene, polypropylene or cardboard, which is welded or glued on the package I 3 here on the outside.
• a carving 3 shaped as a part of a handle, which limits a region 4, which at the top ends in a folding line 5.
• part 2' there possibly is an identically carving 3 ', which like the herein being region 4' and the likewise corresponding folding line 5 ' can not be seen on fig. 1.
• the region 4 is meant for, in connection with the corresponding region 4' on part 2', to be folded around the folding lines 5 and 5' backwards and upwards with the fingers, when the carrying handle is taken into use.
• FIG. 2 On fig. 2 is seen a cross section of the same carrying handle, where the carved areas 4 and 4' together are bent backwards and tightly up against part 2 ' around the folding lines 5 and 5'.
• region 4a approximately in the middle of the figure there is room for up till four fingers to catch and carry the bag in the handle.
• the region 4 in front will after the bending appear as a bit shorter than the region 4' backwards.
• the thickness of the handle in the shown cross sections is shown too big, as it normally just will be of the same or a bit bigger than the thickness of the material to the package 1.
• Fig. 3 shows a corresponding cross section, but here with extra folding lines 5a and 5a'.
• the handle can be supplied with an even softer bending 6, just as the bent regions 4 and 4' can be of different lengths. This contributes to achieve the in the next figure shown locking, so the carrying handle can serve as a stable closing mechanism as well.
• a carrying handle according to the invention which also forms a closing mechanism which can be locked firmly together.
• the carved region 4 in part 2 has here, as the corresponding not shown region 4' in part 2' an extension 7, which when the regions 4 and 4' is bent upwards, together with the corresponding not shown extension 7' in part 2', can be squeezed into and firmly locked into the slits 8 and/or 8 ', as it will appear from the two next figures.
• the handle thereby keeps the bag closed and locked, also after you have set the bag aside, so that the content will not fall out.
• Fig. 5 shows the same shape as in fig. 4, but seen from the backside and in a bent and locked state, with the now empty region 4a wherein the fingers can be placed.
• the extension 7' in the region 4 ' is here preferably in connection with the here not shown extension 7 in part 2 squeezed into the slit 8' and/or into the here not shown slit 8, whereby the two parts of the carrying handle, and thereby the package as well, in a simple way is kept together and locked also after the bag is set free. This especially is an advantage for packages not having a stable shaped bottom. The tight locking also will make the handle even stronger besides the stabilizing effect of the bending itself.
• the two parts 2 and 2' possibly can be exactly identical, so they easily can be punched out together in the same working cycle.
• Fig. 7 shows another type of a carrying handle according to the invention, as the carrying handle here forms a part of the package 1 itself.
• a plastic bag, and usually also a paper bag, is here seen equipped with an extra piece of material 9, attached to the inner side of the bag to add extra material thickness and thereby strength, as it already is known for both plastic- and paper bags.
• the here shown version can possibly, alone on one side of the bag, be reinforced with an extra material, whereby it in the folded state will remind you of the in fig. 7 shown bag, yet now with a shut top edge after folding around the folding line 10.
• This kind of an integrated carrying handle also advantageously can be adapted to plastic bags, if the usual thin material of the bag e.g. on one outer side alone gets one with a print equipped reinforcement before the carving.
• Fig. 9 can serve as an illustration of two different things.
• the carrying handle afterwards can be folded along the folding line 10 to either one or the other side, depending of if it is to be placed on the inner or on the outer side of the bag, after which the attaching can take place e.g. by heat pressure at the same time on both parts 2 and 2 ' without they hereby are glued together.
• plastic bags the same can be achieved by the material for the carrying handle more easily is welded to the bag than to the other part of the handle, when the handle is placed on the inside of the bag, while the material of the bag has a higher mutual sticking point with a placing of the handle on the outer side of the bag.
• This e.g. can be realized by the bag on each of the inner sides is equipped with a piece of a laminate, which side with the highest sticking point, possibly a polyester foil, is facing each other.
• Fig. 10 shows an example of a special shaped package with carrying handles according to the invention, that can be manufactured and delivered without any gluing, but totally flat with folding lines, incisions etc..
• the package e.g. can be manufactured from a stiff and clear plastic foil and preferably be suited to contain light subjects as papers and flowers.
• the idea here fundamentally is, that the totally fiat package first needs to be folded in shape on the place of using, and thereafter can be closed and locked around its content solely by the means of its shape, but without any need for a previous gluing.
• the package afterwards can be reinforced and marked by e.g. tape, as it is common with other kinds of packages.
• the hole produced by the bent region in the carrying handle thereby can, besides for transportation also be used for hanging-up the package.
• This kind of package according to the invention also may be produced of a stronger material and in sizes and shapes, so they can be made and delivered as a totally flat carrying package of e.g. corrugated cardboard both for transportation and for storage.
