Definitions

• the invention relates to a paper bag according to the preamble of claim 1:
• Paper sacks are usually provided as valve bottom bags or block bottom bags for receiving bulk material and have a bottom, a valve bottom, a front, a back and a valve tube inserted into the valve bottom for attachment to the filler neck of a filling device, the valve tube closed by folding or in the case of thermal material can be welded.
• a valve floor bag is known for example from German Utility Model DE-20 2005 004 750 Ul.
• Valve bottom bags are always provided with cover sheets, which serve to avoid the unwanted rising of the folded and glued bottoms, namely the floor and the valve bottom.
• a cover sheet is a piece of paper or paper that is glued to the bottom of the paper sack. Most cover sheets are narrower than the bottom and usually glued not only to the bottom, but also with the laterally projecting from the bottom of the valve tube. However, it is already known to pull the cover sheets over the edges of the base and the valve bottom into the region of the front and the back of the paper bag.
• the object of the invention is to develop a paper bag with tear strip to the effect that when tearing any paper fibers can get into the product.
• a film is inserted in a paper bag of the type mentioned under the stand-cover sheet and / or under the valve cover sheet and releasably bonded to the paper bag in the manner that the film after tearing the floor or bottom of the valve - Cover sheet still completely closes the paper bag and releases the product only after peeling off.
• the film may be a plastic film, a metal foil, a paper foil with or without a coating, a glass fiber foil, a tissue foil or a spunbond of tissue fibers, wherein the foil material should also be biodegradable, compostable or recyclable if necessary.
• Figure 1 is a plan view of a paper bag with floor stand, valve bottom and hose valve;
• Figure 2 is a schematic representation of the floor during tearing;
• Figure 3 shows the torn open and unfolded according to Figure 2 floor, which is still closed by a film
• FIG. 4 shows the beginning of the detachment of the film in the case of the floor opened according to FIG. 3;
• FIG. 5 shows the already half-opened paper bag according to FIG. 4;
• FIG. 6 shows the paper bag from FIG. 3 with further features.
• Figure 1 shows a paper bag 1 with a floor 2 and a bottom plate 3, which are folded in a conventional manner as Wienböden or block floors and covered by a respective cover sheet 5, 5 '.
• the cover sheets 5 and 5 ⁇ are guided in the illustrated embodiment over the edges of the base 2 and the valve bottom 3 into the region of the front wall 4 and the rear wall and glued in the usual way with the paper bag 1.
• valve tube 7 is further incorporated into the valve bottom 3, as is known from the prior art, for example, from the utility model DE 20 2005 004 750 Ul.
• Figure 1 the paper bag 1 is shown so that the floor 2 is directed upwards, as would be advantageous for tearing a paper bag 1 filled with product.
• Figure 2 now shows the process of tearing the stand-cover sheet 5 in a schematic representation, wherein only the upper part of the paper bag 1 is shown with front wall 4 and a side wall. It detects the tear strip 6 in the vicinity of the side wall 8 and pulls him direction of the arrow to the opposite side wall 8 ⁇ .
• Figure 3 shows the paper bag 1 with completely torn cover sheet 5 and unfolded side strips 5 ", the paper bag 1, however, is still closed by an inserted and with the cover sheet strip 5" releasably bonded film 9 made of plastic.
• the film 9 To open the paper bag 1, the film 9 must first be separated from the side strips 5 ", which is indicated in Figure 4 by a corner 10 of the film 9 is detected and the cover sheet side strip 5" is replaced. In this state, ie when the film 9 has not yet been removed, the product is not yet exposed, since the interior of the paper bag 1 is still closed.
• FIG. 5 shows the still further detached film 9, which releases the interior 11 of the paper bag 1. If the film 9 is then completely withdrawn from the paper bag 1, there is unhindered access to the lying in the interior 11 product without this would have been contaminated during opening by paper fibers.
• Figure 6 shows a development of the invention, in which the film 9 is provided with a reclosing device.
• the reclosing device consists of the application of special adhesive or special glue which allows the film 9 to be detached from the paper bag 1 as often as desired and to be reattached.
• special adhesive or special Glues' are known in the art.
• adhesive lines along the edge of the film 9 can be provided or it can also be the entire film 9 coated with such a special adhesive.
• a closure 13 is provided, which lies in one embodiment under the not glued in this area film 9, while in another embodiment, the film 9 is narrower and not up to the But leaves a strip in which are located the two parts 13 ', 13 "of the closure 13.
• the closure 13 in one embodiment is a click-in closure with tongue and groove, in another embodiment a hook-and-loop fastener
• the side strips 5 "of the torn cover sheet 5 and, after the foil 9 removed, are pressed against one another, whereby the spring 13 'is pressed into the Groove 13 "of the closure 13.
• a Kle Closure closed namely by the two parts are pressed against each other.
• the once opened paper bag 1 is re-closable in a simple manner.
• the film 9 according to the invention can be printed or unprinted and also provided with security features such as images, holograms or stripes, which ensure that they reveal the film 9 as damaged after the first removal or detachment from the paper bag 1.
• the film may also be provided with instructions on the contents of the product or with instructions on how to handle the paper bag or the product contained therein.
• the film 9 can serve to form a bulk material together with the inwardly folded bottom, for which the film 9 expediently in the area or in the vicinity of one of the side walls 8 or 8 'not glued to the paper bag 1 is.
• the film 9 covers the interior of the paper bag 1 in this area, it can be turned over by hand after the tearing strip 6, which is shown in FIG. 2, has been torn open so that the folded-over part of the base 2 is grasped by hand can be pulled outside in the direction of the side wall 8 or 8 '.
• the folded-over part of the stand 2 is provided with incisions which are approximately parallel to the front wall 4 to the side wall 8 or 8 ', then the folded part of the stand 2 by hand can pull outwards and forms together with the previously in the In the other direction folded over part of the anchored film 9
• a dispensing device which is particularly well used when the standing bottom 2 opposite bottom, which is designated in an embodiment of Figure 1 as a valve bottom 3, has a carrying handle. Then a user can comfortably grasp the carrying handle and empty the product through the dispensing device formed by the folded-up film 9 and the raised floor area.
• the film 9 can also be provided in the vicinity of the side edges 8 or 8 'with recesses 14, 14' in the form of holes or punch-outs which serve to hang the film 9 alone or together with the opened paper bag 1, for example on a nail or a hook. This is particularly advantageous if the film is provided with instructions for use, which can give the user after detachment from the paper bag 1 assistance for the utilization of the product.
• the inventive paper bag 1 on the cover sheet 5 of the base 2 and / or the valve base 3 have a carrying handle which runs parallel to the tear strip 6, wherein when the carrying handle is arranged centrally on the ground, the tear strip (6) in the case not centered to the cover sheet (5, 5 ') runs.
