Description

Bag with information surface.

The invention relates to a bag with a wall, composed of at least one layer of flexible material, to from which by folding sections in one direction longitudinal and a durable band-shaped joint that runs in the longitudinal direction of the folded and placed sections one on top of another, it is a flexible tubular shape with two ends open, of which a first end is closed to fill the bag and a second end is planned to close after the filled, an outer face of an outer layer of printing being printed Wall.

Such bags can be manufactured in many ways. constructive As flexible materials, they are considered in particular plastic sheets and paper layers, in particular layers Kraft paper for bags. In kraft paper layers bags for bags that can be heavily loaded usually a multi-layered structure, one layer being interspersed intermediate of a plastic sheet as a vapor barrier and humidity. In particular for small loads it can also be configured the bag by a single layer, so that a layer forms a the outer layer of the bag wall at the same time.

Document FR 2 667 846 A1 discloses a single layer bag in the form of a shopping bag that presents a large anterior face and posterior face, joined together by a folding line. In the area of the folding line are fixed additional layers, which by their free ends are fixed to the aforementioned large surfaces with paste points. Tearing apart Paste points can be perceived information and illustrations  over the wall sections covered by the double layers, which they form the front face and the back face of the bag, so about the inner face of the additional wall. Tearing the walls doubles thus have information surfaces additional.

The closure of the bag at its first end (which shape the bottom face) can be done by gluing, welding or preferably by forming a folded bag bottom and glued. Cross-bottoms and square bottoms are common in this regard, that with its rectangular bottom shape condition that the section of the bag when filled is approximately rectangular.

The bag can be filled as an open bag by the top and then close the face opening upper, for example by multiple folding and / or gluing, Stitched or similar. The configuration is also known, already before filled, with a bottom folded and also glued at the second end, which has a filling opening provided in the case of a tube flexible valve. The closure of one such valve bag is performed after filling by closing the valve by gluing, welding or simply flattened, for example by filling pressure of the bag is full when it is thrown to the ground after filling on the bottom fitted with the filling valve.

Known bags are printed, at least partially, in its outer layer, to identify the content of the bag, advertise the product and give the user indications on the use of the material with which it is full. The internationalization of trade implies that indications of use have to be given in several languages, so that indications of use can be understood in all countries to those that the product is exported. Already due to the market increase European common is a considerable increase in languages Officers in the affected countries. This results in that on the bags of the type cited every time should be made available more Information surface for indications of use. For a certain bag size, information surface Available reaches its limits. To be able to host the information necessary should therefore be printed these with less and less size, so that the readability of the information you should occur in daily life with utilization, it looks strongly affected.

Document DE 203 12 185 U1 contains an indication of a proposal to print the inner side of the outer layer on a multilayer bag, so that when the bag is opened the outer layer is torn in order to know the indications for use of the inner face of the outer layer. This solution is not useful, because the stability of the bag must be completely maintained even when it is opened or after opening it, in order to handle the bag, if necessary, in an appropriate way to daily life. As a result, the bag should therefore be manufactured with an additional layer, only to be able to print the information. Since the outer layer is directly subjected to environmental influences during transport, the resistant and therefore expensive outer layer must be constituted, for example by kraft paper for bags. The costs that arise due to the additional layer return to the uneconomic solution. Document DE 203 12 185 U1 therefore includes the proposal to attach information material to the bag afterwards , for example in the form of an accordion, for example by adhesion. This solution is equally expensive, requires special process steps after the bag is manufactured and also does not ensure that the additionally placed indications do not start during the hard handling of the bags during transport and storage and therefore no longer remain available to the user.

The present invention therefore has as basic task make available a bag of the aforementioned type mentioned that it presents additional information surfaces without that they have to be fixed subsequently to the bag.

To solve this task, it is characterized according to the invention a bag of the type mentioned at the beginning because both Wall ends are folded and glued to form a bottom which determines a rectangular shape of the full bag and the bottom presenting at the second end a filling opening, because one of the sections of the outer layer stands out with a section end beyond the junction, extending around an edge to an adjoining side of the wall and being fixed with its end free such that it can be easily released to the outer layer that found under it, because an information surface additional can be released after releasing the extreme stretch and because the extreme section is housed in the folding of the funds and presents  in the transition to the folded bottom a tear hole that It extends to the lasting bond.

The one who can easily let go of the union separable from the extreme section with the area below the outer layer results in the extreme section being deployed around the durable band-shaped joint that is necessary For the flexible tube shape.

The additional information surface can be advantageously free by a face impression inside the end section for the user, without due to this the stability of the bag is affected. Alternative or in addition to this, you can preferably stay between the extreme section and the area under the layer outside a printed insertion sheet, which has a  information surface corresponding to the size of both sides of the insertion sheet.

According to the invention, they are folded and glued both ends of the bag to give rise to a fund that conditions a rectangular bag shape for the full bag. The extreme stretch It is housed in the ground folding. This is favorable in terms of manufacturing technique because bag manufacturing can be done in the traditional way with an outer layer that extends along the extreme section, which in the area of the extreme section It has the same length that is needed to manufacture the bag with the bottom folds.

The extreme stretch presents in the transition to the bottom folded a tear hole, which extends to the lasting union. The tear of the extreme stretch across the width of the bag, necessary due to the folding of the extreme section in the area of the bottom, can be done with a cleaner tear piercing and without the danger of tearing information surfaces necessary.

The durable joint is preferably arranged as stuck in the form of a band and preferably in the center over a large side of the bag parallelepipedically when it is full. The extreme section can then extend to an edge of the bag that represents the transition to a small side of the bag, but preferably also around the edge to the Small adjacent side of the bag. Naturally it is also possible in this way increase the folding end section by separating the durable joint position of the large side of the edge bag towards which the extreme stretch extends.

When the surface is further increased of information by means of an inserted insertion sheet, it is housed preferably also at the same time the insertion sheet in the folding From the bottom. In this way it is possible to fix the insertion sheet exclusively by folding the bottom to the outer layer. Since the insertion sheet is protected by the outer layer of the bag, it can be formed by a paper relatively simple and with it can easily be torn in the transition zone towards the ground folded across the bag, this tear can also be facilitated by a tear piercing.

By the present invention it can be realized thus at least one additional information surface, for which the manufacturing of the bag does not have to be basically modified and which is made available in the bag manufacturing process, that is, it does not require any subsequent stage, for example to house a manufactured and packed information surface separately.

The invention will be described below in detail based on an example of execution represented in the He drew. It is shown in:

figure 1 a perspective view of a shape construction of a bag corresponding to the invention when find full;

figure 2 a perspective representation according to Figure 1 with a section of the outer layer deployed for release information surfaces;

figure 3 a view according to figure 2 with a insertion sheet additionally housed.

The bag represented in figure 1 when found full presents a cylindrical wrap wall 1, which by means of a glue 2 with a band shape it is closed with a flexible tube. The glue is drawn in figure 1 with line discontinuous for an outer layer 3 of the various paper bag layers. The outer layer 3 is extended with an end section 4 more beyond glue 2. End section 4 is fixed at its end free to an area of outer layer 3 below thereof, for example by means of an adhesive (not shown) applied in the form of a band, which can be easily released.

In the example of execution represented this closed the flexible tube formed by the wall 1 with a first bottom 6 on the lower face and a second bottom 7 on the upper face. For it is folded and glued the corresponding ends of the wall 1 in the known way to form the bottom 6, 7, here in each Case a cross bottom. In the known way it is inserted between the bottom folds and the corner fold of the cross bottom a flexible valve tube 8 and the bottom is covered with a sheet bottom cover 9.

In figure 1 it is indicated with dashed lines an information surface 10 covered by the end section 4, which is intended to print for example directions of use.

Figure 1 also shows that starting from free edge 5 of the end section 4, in the transition towards the bottom 6, 7 respective drilling lines 11 are provided in the extreme section 4, which extends to glue 2.

Figure 2 shows that the end section 4 can deploy for example by removing the adhesion surface and tearing along the perforation line 11 to the line of durable bonding 2, so that the information surface 10 is released on the outer face of the outer layer 3, initially covered by the extreme section 4. It can also be printed the end section 4 on its inner surface 12 also with an information surface 10 '.

Figures 1 and 2 indicate that the extreme section 4 It has a length that is folded at the same time in the bottoms 6, 7. For the dejection of the end section 4 shown in the figure 2 from the outer layer 3 of the wall 1, must therefore loosening the end edge 5 of the end piece 4 as well as also a separation of the end section 4 of the tranches that are introduced in funds 6, 7, which is facilitated with the help of perforation lines 11.

The execution example shown shows a extreme section 4, which extends from the glue line 2 on the center of a large side of the wall 1 around a edge 13 to a small side wall adjacent to wall 1. This has the advantage that fixing the end section 4 to the area under the outer layer 3 is made over the small side wall, so that the large side wall is available up to edge 13 for the information surface 10.

In the example of execution represented in the figure 3 has stayed in the intermediate space between the section end 4 and the section under the outer layer 3 an interleaved sheet 14, which can be printed on both sides and thus information surfaces are made available additional.

The inserted sheet 14 has a width that is somewhat less than the distance between the glue 2 and the edge 13. The length of the inserted sheet 14 is chosen such that the sheet inserted 14 is folded with both ends on the bottoms 6, 7 and in this way it is joined with the outer layer 3. A joint additional with outer layer 3, for example by gluing or similar, it is not necessary therefore, with what the surface of information on the inserted sheet 14 is not reduced by bonding surfaces or the like.

It is clear to the specialist without more than inserted sheet 14 is housed during the normal manufacturing process  of the bag, which after the bag manufacturing process proper they are not necessary even for the surfaces of information 10, 10 'nor for the information surfaces of the sheet inserted 14 additional process steps.

Since the end section 4 is formed by the material of the outer layer 3 configured such that it is resistant,  the information surfaces 10, 10 'and the inserted sheet 14, by hosted example, they are reliably protected during the transport, without requiring an additional expense.
