Description

The present invention relates to a mailing bag, in particular a mailing bag for online trading. The invention also relates to a method for producing mailer bags. Furthermore, the invention relates to the use of such a shipping bag for transporting shipping goods, in particular shipping goods of the online trade.

Shipping bags are used in various forms for shipping purposes. Such shipping bags, in contrast to conventional shopping bags often have a closable opening, the shipping goods should usually not be recognizable and must also be protected during transport. Often such shipping bags have no handle hole. Plastic bags, as they are usually provided in the supermarket, on the other hand, often have a grip hole. However, there are also shipping bag with handle eg from the DE 10 2009 007 985 known.

In shipping bags handle holes are usually avoided. They are implemented, if they exist, by punching the handle hole into the shipping bag shipping area of the shipping bag. A major disadvantage of conventional shipping bags is that they are often not sufficiently weather-protected, for example, to be able to withstand rainfall. Shopping bags are usually open in the direction of the handle holes and thus unsuitable as a shipping bag. In shipping bags without handle holes this problem is solved by these are completely sealed. Handle holes are deliberately avoided in order not to impair the sealing of the goods. Through a grip hole, the contents of the ambient conditions, in particular the ambient humidity, exposed, which is absolutely unavoidable with shipping bags.

Alternatively, handles may be glued or welded to the outer surface of a shipping bag. This requires a costly further manufacturing step, in particular a further weld or bond line. Due to the high circulation at Versandbeuteln, the production costs here are to be calculated particularly carefully.

Also, the bag front wall and bag back wall are usually made of a thin material to reduce said manufacturing costs and to protect the environment. Handle holes or externally mounted handles are usually not stable enough attached in these cases to allow safe transport by wearing the handle hole or handle. It is disadvantageous that finger holes are usually not sufficiently stabilized by the surrounding material. Regularly, they are even attached to weak points, such as the opening of a mailer. Thus, the problem of low load capacity is thereby exacerbated. This is particularly unacceptable for a mail-order company, especially given the fact that, for example, expensive branded apparel for ladies and / or gentlemen are often shipped in such mailer bags. Furthermore, it is disadvantageous that the closure load of a mailer can unintentionally open due to the tensile load; of the DE 20 2012 010643 U1 is to be taken from a shipping bag according to the preamble of claim 1. The object of the invention is to design a shipping bag so that the above-mentioned disadvantages are overcome. In particular, it is the object of the invention to keep moisture, for example in the form of rain, from the contents of the shipping bag with handle holes. Furthermore, the shipping bag with handle hole to allow a simple, accident-free and protected transporting the contents. In addition, the production cost of the shipping bag according to the invention should be low. The invention was also based on the object of making available a bag with which the contents can be protected against manipulation and damage, in particular against uncontrolled access by unauthorized third parties. Furthermore, the invention has the object to provide shipping bag available, which are very user-friendly and can still be produced without problems, cost and process optimized. Finally, the invention was based on the object to make shipping bag available that ensure the mail order retailer optimum ease of use.

Accordingly, there has been found a shipping bag comprising an upper bag end, an opposite lower bag end, a first bag edge and an opposite second bag edge, and a bag front wall and an opposite bag back wall, the bag front wall and bag back wall each having a top edge, a top edge Lower edge, a first side edge and a second side edge and in particular are each limited by this, wherein bag front wall and bag rear wall between the upper bag end and the lower bag end by at least one at least partially extending in the direction of the first bag edge to the second bag edge connecting element, in particular a first weld and / or bond line, forming a first bag section containing the upper bag end, and a second bag section containing the lower bag end, the first bag section comprising at least one goods receiving area and the second bag section having at least one grip hole weakening zone, as specified in claim 1 in more detail. Accordingly, it can be provided that the grip hole weakening zone is formed by a circumferential weakening line describing a grip hole, in particular a perforation line, or by a not completely circumferential weakening line, in particular a perforation line.

A grip hole weakening zone may accordingly constitute a weakened zone, for example in the form of a perforation line, for forming a grip hole in the sense of the present invention. For example, to form the grip hole, it is sufficient in some cases if the perforation is partially destroyed. In that the weakening or perforation line is not completely circumferential but omits an area, the material of the bag pushed out of the weakening area can remain on the bag itself releasing the handle hole and does not contribute to the contamination of the environment and is not to be disposed of separately , Rather, it can be recycled as part of the shipping bag after use together with the rest of the bag. Designs for handle holes can therefore be easily transferred to grip hole weakening zones. The embodiments with grip hole weakening zone can be transferred, preferably at the time of use by the user or wearer of the shipping bag, by destroying the grip hole weakening zone into an embodiment with a grip hole. Due to the fact that no grip holes but only grip hole weakening zones are provided during the production of the shipping bags according to the invention, surprisingly the proportion of rejects during production can be considerably reduced. Also, the ease of use can be significantly increased on the part of the mail order company using these shipping bags. For example, the filling and / or the transport, in particular the transport on conveyor belts, much less error prone.

A grip hole in the sense of the present invention is a usually elongate opening in a two-ply material with a bag front wall ply and a bag back wall ply designed and arranged to facilitate carrying the bag, particularly a shipping bag. In particular, the handle hole may be an opening in the bag front wall and bag back wall, designed and arranged to facilitate carrying the bag, particularly shipping bag. Although here two openings (one in the bag front wall and the bag rear wall) are produced, only a handle hole is formed when the opening of the bag front wall and the bag rear wall are arranged opposite each other (which is usually against the background of a V-shaped fold at the respective lower edges Bag walls is the case). This is usually achieved already in the production by the opening or Grifflochschwächungszone is generated simultaneously by a process in both films.

The connecting element in the sense of the present invention connects two material layers. Such a connection element can be, for example, a sewing seam or a weld seam. Preferably, in particular with plastic shipping bags, is a first weld. The shipping bag according to the invention is preferably a plastic shipping bag with at least one first weld. Also, the connector may comprise a glue line. In such a bond line, two layers of material are connected to one another by a line-shaped or strip-shaped, preferably continuous, applied adhesive. The connecting element, in particular the first weld seam and / or the bond line preferably extend from the first bag edge to the opposite second bag edge. Surprisingly, it has also been shown that it is advantageous if the access opening to the goods receiving area is not present in the second bag section. Access openings for the placement of articles in the goods receiving area regularly represent material weaknesses in the construction of a mailer, which, however, in the present invention, the stability of the through-hole not or only slightly affect. By attaching the at least one Grifflochschwächungszone or the at least one handle hole in a region which at least partially, in particular completely, by the connecting element, the first weld and / or the bond line is delimited, the material strength can be surprisingly significantly increased. In particular, such a seam and / or bond line can bring about a better distribution of the tensile forces emanating from the grip hole. Furthermore, no hole in the wall of the at least one goods receiving area is created by the invention Grifflochschwächungszone by the separation by means of seam and / or Verklebungslinie. This has the consequence that impurities or moisture can not pass through the Grifflochschwächungszone or the resulting grip hole in the goods receiving area.

A shipping bag according to the present invention is a bag provided for transporting goods, in particular goods of online commerce. Such a shipping bag is preferably closable, in particular so that no opening remains unlocked. The shipping bag usually has at least one goods receiving area with an opening, which can preferably be substantially completely closed. Bags that have non-closable openings that allow inadvertent dropping out of shipping items during transport, are generally unsuitable as a shipping bag. It is fundamentally conceivable to deform a shipping bag so that a precise description of the geometry is no longer possible. The remainder of the description should therefore be preceded by the fact that the description refers to an unfilled, undeformed state of the mailer, wherein the mailer is preferably to be considered substantially flat. In this form, the shipping bag is also usually provided before being filled with shipping items.

In a particularly preferred embodiment, the shipping bag is a plastic shipping bag. The bag front wall and / or bag rear wall preferably comprises at least one thermoplastic material. In particular, it is preferred if the bag front wall and / or bag rear wall is formed or consists of at least one thermoplastic material. Particularly suitable plastics are known to be polyesters and / or polyolefins. Plastics, in particular the above-mentioned plastics, are as a rule more tear-resistant than alternative materials such as, for example, paper. In addition, plastic bags are very light and preferably waterproof, which is advantageous in shipping.

Preferably, at least one bag wall, in particular the bag front wall and / or bag back wall, made of plastic, which is impermeable to water and / or light. Opaque means here that the light intensity is significantly reduced by the respective bag wall, preferably at least 30%, in particular at least 50% and more preferably at least about 70%. The impermeability serves to protect the shipping items, especially against weather-related influences such as rain, snow or humidity. The reduction in light intensity also serves to protect, for example from UV fading, but is also important to meet the requirements of postal secrecy where appropriate. Due to the folding connection, the front wall of the bag and the rear wall of the bag are made of the same material, in particular of the same thermoplastic material. The invention thus provides that the front wall of the bag and the rear wall of the bag are based on a contiguous section of a contiguous strip of material, in particular a coherent plastic film, wherein the bag front wall and bag back wall are preferably formed from a continuous section of a continuous plastic film and delimited only by a folding edge. Said folding edge also forms the lower edge of the bag front wall and bag rear wall. This is designed as a cross-sectionally V-shaped fold (also V-fold). Therefore, the lower edge of the bag front wall is connected to the lower edge of the bag rear wall via a cross-sectionally V-shaped fold. The V-shaped fold is not to be understood as limiting the angle between the legs. Preferably, the bag front wall and bag rear wall abut each other. The structure described above has the advantage that the production can be significantly simplified and manufacturing costs are reduced. In particular, in this case no welds are required to connect the bag front wall and bag rear wall. The grip hole weakening zone and the resulting grip hole have a longitudinal extent that extends parallel to the lower edge. Particularly preferably, the Grifflochschwächungszone and the resulting grip hole are oval or rectangular with rounded corners. It has been shown that the Grifflochschwächungszone or the resulting grip hole through the lower edge, in particular the V-fold, particularly well against tensile forces, as they are common in the generic use or when wearing the mailer, is stabilized.

In particular, the grip hole weakening zone or the resulting grip hole preferably has an average distance of less than 5 cm, in particular less than 4 cm and particularly preferably less than 3 cm from the connecting element, in particular the first weld seam and / or bond line. This is advantageous since it makes it possible to obtain the tensile forces which are customary in the generic use or when the shipping bag is worn, e.g. the first weld and / or bond line are distributed, so that stabilization takes place.

In one embodiment, the handle hole weakening zone and the resulting handle hole have an average distance of less than 5 cm, in particular less than 4 cm and particularly preferably less than 3 cm from the lower edge of the bag front wall and / or bag rear wall. This is preferred because a small distance facilitates embracing. Nevertheless, the distance is preferably greater than 0.5 cm, in particular 1 cm. This has the advantage that the stability of the film area between the handle hole weakening zone or the resulting handle hole and lower edge of the bag front wall and / or bag rear wall is sufficiently high.

In one embodiment, the connecting element, which separates the first and second bag sections, is a first weld, in particular a thermoplastic weld. For the purposes of the present invention, a weld seam is preferably produced by heating or (melting) a narrow film region of a thermoplastic, in particular to a temperature above the glass transition temperature. By applying pressure, a connection of the now welded parts is obtained after cooling. It has been found that welds are particularly well suited to inexpensively and securely connect the bag front wall and bag back wall.

Preferably, the connecting element, in particular the first weld and / or bond line, limits the goods receiving area in the direction of the lower end of the bag. In particular, a first weld between the first and second section, which the goods receiving area waterproof limited towards the lower end, is preferred. In this case, water, even if it should penetrate through the grip hole weakening zone or the resulting grip hole, does not enter the goods receiving area.

In one embodiment of the shipping bag according to the invention, the connecting element, in particular the first weld and / or bond line, extends linearly, preferably substantially parallel to the lower edge of the bag front wall and / or bag rear wall. Such a connection element, in particular first weld and / or bond line, can be manufactured particularly simply and cost-effectively. Furthermore, such a connecting element, in particular such a weld and / or bond line, distributes the tensile forces particularly effectively. Also, the inside of the goods receiving area is provided with a linear bottom end (formed by bringing together the front wall of the bag and the rear wall of the bag at, for example, the first weld and / or bonding) so that goods are particularly well placed therein.

In a preferred alternative embodiment, the connecting element, in particular the first weld and / or bond line, is curved at least in sections. In this case, it is advantageous if the connecting element binds to the bottom edge and / or to at least one side edge of the front wall of the bag and / or rear wall of the bag, in particular of the front wall of the bag and the rear wall of the bag, via at least two attachment points (hereinafter also referred to as first and second attachment point). Preferably, the at least two attachment sites are the two ends of a first weld and / or bond line. Preferably, the connecting element has exactly two attachment points at the lower edge and / or at least one side edge of the bag front wall and / or bag back wall.

In this case, the connecting element preferably extends starting from the lower edge of the front wall of the bag and / or the rear wall of the bag, in particular so that the first and second connecting points are located at the lower edge of the bag front wall and / or the bag rear wall. Further, it is preferred if said attachment points or ends are respectively spaced from the first bag edge and the second bag edge connected to the lower edge, in particular spaced at a distance greater than 1 cm, preferably greater than 2 cm.

In a further embodiment of the invention, the first attachment point is located at the lower edge of the bag front wall and / or bag rear wall and the second connection points of the at least partially curved connecting element at the first side edge or second side edge of the bag front wall and / or bag rear wall. In a further preferred embodiment, the first attachment points of the at least partially curved connecting element is located on the first side edge and the second attachment points on the opposite second side edge of the bag front wall and / or bag rear wall.

According to the invention, the method in claim 15 provides that the first bag edge is formed by welding the first side edges of the bag front wall and bag back wall to a second weld seam and the second bag edge by welding the second side edges of the bag front wall and bag back wall to a third weld seam. This is advantageous because it maximizes the pickup area for shipping items.

In an alternative embodiment, the welds do not coincide with the first and second side edges, but are, in particular slightly, spaced therefrom. In this case, it is preferred if the first bag edge comprises a first weld which extends at a first average distance from the first side edges of the bag front wall and the bag rear wall and the second bag edge comprises a second weld which is at a second average distance from the second side edges of the bag front wall and bag back wall runs. Preferably, the first average distance and the second average distance are equal. Furthermore, it is preferred if the first mean distance and / or the second mean distance is less than 3 cm, in particular less than 2 cm and preferably less than 1 cm. Welds that are not directly on the side edges often have increased stability.

Preferably, the second bag section in the bag front wall and the bag rear wall, in particular circulating, no openings. This second bag portion is in a particularly advantageous embodiment substantially rectangular, with all four edges of the rectangle are closed. This has the advantage that water can not pass through the Grifflochschwächungszone or the resulting grip hole in the goods receiving area. Furthermore, the tensile stability of the Grifflochschwächungszone or the resulting handle hole much higher when it is enclosed by an edge-sealed second bag section.

Preferably, the second bag portion has a transverse extent, in particular in the direction from the first bag edge to the second bag edge, and is limited in its longitudinal surface extent by the lower bag end and the connecting element, in particular the first weld. Weld seams for elongate second bag sections can be produced easier according to experience. Also, in an elongate second bag section, there is sufficient space available for a grip hole weakening zone, and these preferably also have a longitudinal extension, in particular rectified. In one embodiment, the second bag portion is limited in its transverse surface extent by the first bag edge and the second bag edge. This simplifies production. A separate limitation of the second bag portion in its transverse extent is not required here. Also, in such a bag section, a tensile load of the grip hole weakening zone or the resulting handle hole is known to be distributed over a larger area, which benefits the draft stability of the grip hole.

In particularly preferred embodiments, the part of the bag rear wall lying in the second bag section does not occupy more than 30%, in particular not more than 25%, particularly preferably not more than 20% of the total bag rear wall. A higher area requirement of the second bag section, according to experience, unfavorably restricts the goods receiving area. The grip hole weakening zone or the resulting grip hole usually also comprises at least two layers, in particular the bag front wall and the bag rear wall, wherein the opening or weakening zone in the bag front wall is usually rectified and identically shaped with the opening or weakening zone in the bag rear wall. If the second bag section is not too large, these two openings better come to rest against each other.

According to the invention, the shipping bag has at least one opening (first opening) to the goods receiving area. Preferably, it is an opening which is arranged in the first bag section. In preferred embodiments, the first opening in the first bag section is located in the bag front wall or in the first bag section in the bag rear wall. Particularly preferred are embodiments in which the first opening between the bag front wall and the bag rear wall is located in the first bag section. Preferably, the first opening is disposed on the opposite side of the end of the bag wall where the grip hole weakening zone or the resulting handle hole is located. Particularly preferably, the first opening is arranged between the upper edges of the front and back. A corresponding shipping bag can be made easier. Furthermore, the large spacing between the grip hole weakening zone or the resulting grip hole and first opening of the goods receiving area causes a lower tensile stability of the shipping bag in the region of the first opening of the goods receiving area does not significantly affect the tensile stability of the handle hole or the handle hole formed by the Grifflochschwächungszone. According to the invention, the bag front wall has a first length which corresponds to the mean distance between the upper edge and lower edge of the bag front wall and the bag rear wall has a second length which corresponds to the average distance between upper edge and lower edge of the bag rear wall. In this case, the first length is shorter than the second length, so that the bag rear wall protrudes at the upper end of the bag over the bag front wall. This is advantageous since the protruding portion of the bag rear wall can be folded over in order to close the first opening preferably.

It has also proven to be advantageous if the bag rear wall is larger than the bag front wall, but preferably not more than 30%, in particular not more than 25% and particularly preferably not more than 20% larger than the bag front wall. Typically, this creates a projecting portion of the bag rear wall, which can be used on the bag front wall, in particular for closing an opening to the goods receiving area, preferably the first opening. It has been found that the above-mentioned percentage size difference has sufficient large portions provide a more secure closure. Too large areas can possibly also fix much worse.

Also, the bag front wall preferably has a first width which corresponds to the average distance between the first and second side edges of the bag front wall and the bag rear wall preferably has a second width which corresponds to the average distance between the first and second side edges of the bag back wall. The width of the bag front wall is less than the length of the bag front wall and the width of the bag rear wall is less than the length of the bag rear wall. This has the advantage that the grip hole or the grip hole weakening zone is arranged on the shorter part of the shipping bag, resulting in a higher stability.

Preferably, the at least one opening to the goods receiving area of the shipping bag, in particular the bag rear wall, at least one fastening means, said at least one fastening means, in particular after folding the bag rear wall on the bag front wall, is designed to close an opening to the goods receiving area. Alternatively or additionally, the bag front wall may also have at least one fastening means to close said opening. By folding the bag is only slightly deformed, so that, for example, documents are not kinked. In particular, an opening using, for example, a drawstring to narrow the opening to full closure would be less suitable for documents in many cases.

Preferably, the first opening can be closed with at least one adhesive strip. This would preferably extend along the upper bag end, in particular along (and optionally spaced from) the upper edge. In a preferred embodiment, the adhesive strip extends from the first edge of the bag to the second edge of the bag. Adhesive strips allow a fast and secure sealing.

In a preferred embodiment, the closable opening with a fastening means, preferably with at least one adhesive strip, in particular irreversibly closable, wherein preferably the bag rear wall on the inside and / or the bag front wall outside said fastening means, in particular so that these with the bag front wall or the bag rear wall for conditioning come if a section of the bag back wall is folded onto the front wall of the bag.

Said adhesive strips preferably have a width between 0.3 cm and 3 cm, in particular between 0.5 cm and 2 cm. By the appropriate width, a secure closure of the opening is ensured, in particular an unintentional opening of the shipping bag is avoided. In a further preferred embodiment, the closable opening of the upper end of the bag is irreversibly closable. This is advantageous because it ensures that the opening can not open during transport, in particular when worn on the handle hole.

Particularly preferred are embodiments in which the at least one fastening means comprises two spaced-apart adhesive strips with a destructible zone, in particular a weakening line, between said adhesive strips. Preferably, they are substantially parallel adhesive strips, with a destructible foil region extending between said adhesive strips. Preferably, the first opening is located between the upper edge of the bag front wall and the upper edge of the bag rear wall. Thus, the adhesive strip, which is closer to the upper bag end, can be used to first close the bag, in particular the first opening. The destructible film area can be destroyed to reopen the mailer. By destroying the film area, a second opening is created between the top edge of the bag front wall and the destructible film area, which may be aligned substantially parallel to the original opening (first opening). Preferably, the former (now closed) first opening and the newly obtained second opening in the immediate vicinity, ie on average not more than 7 cm, preferably 5 cm apart. The second adhesive strip, which is further spaced from the upper bag end, can now optionally be used to close this second opening as well. In an advantageous embodiment, the said film region comprises at least one line of weakness or weakening zone between spaced-apart adhesive strips. In a particularly preferred embodiment, the closable opening of the upper bag end is irreversibly closable with the adhesive strips described above, wherein a line of weakness between the adhesive strips is provided for forming the second closable opening. For the purposes of the present invention, essentially parallel means that the deviation from a parallel orientation is less than 10 °, preferably less than 5 °. Preferably, the average distance between the spaced adhesive strips less than 9 cm, in particular less than 7 cm and particularly preferably less than 5 cm.

In one embodiment, the shipping pouch has only a first opening or opening and a second opening such that the receiving area for shipping articles is trapped by closing the first opening or first or second opening and no moistening / contamination / contamination by further openings , It should be pointed out that a weakening zone, in particular a line of weakness in the form of a perforation line, does not yet constitute an opening for receiving and removing goods within the meaning of the invention, but only an area in which, if appropriate, a third opening is particularly damaged by destruction of said weakening zone easy to generate.

Since, according to the invention, the first opening and, if appropriate, the second opening usually point downwards when worn on the handle hole, it is advantageous to use an irreversible closure for the first and possibly the second opening, since an accidental reopening is usually precluded. The irreversible closing of the first opening is particularly advantageous when at least one such third opening, for example, due to weakening zones, in particular lines of weakness, can be easily formed. In a preferred embodiment, the bag front wall and / or bag back wall comprises a weakening zone, wherein the destruction of the weakened zone releases the at least one third opening. This allows the third opening to be formed to take a shipping item. The weakening zone may be a weakening line, which is preferably linear or curved. The presence of a third opening does not imply that the second opening described above must necessarily be present as well. Preferably, the first, second and / or third opening can be closed with at least one adhesive strip. The third opening is preferably not in the immediate vicinity of the first opening.

In a preferred embodiment said weakening zone, in particular weakening line, is arranged to form the third opening in the bag back wall or bag front wall. Here, it is advantageous, if accidental tearing of the weakening lines during wear does not lead to a gravity-driven removal of the articles, that the third opening points to the side when worn.

The invention also relates to a method, specified in more detail in claim 15, for producing a bag, which comprises in the following method steps:

1. a) providing a first film strip or film strip made of thermoplastic material to form the bag front wall and bag back wall;
2. b) folding the film strip or film strip along a fold edge such that a film area joins the bag front wall and the bag back wall at the bottom end;
3. c) forming a connecting element, in particular a weld (first weld seam) or bond line, substantially parallel to the folded edge, preferably at a distance of 1.5 to 15 cm to the folding edge;
4. d) forming at least one grip hole weakening zone, in particular by attaching at least one perforation line, in the region between the folded edge and the connecting element, in particular the weld seam or bond line;
5. e) formation of two spaced side edges (also first and a second side edge) substantially orthogonal to the folded edge by welding the bag front wall with the bag rear wall, wherein the film strip is optionally severed at the side edges.

The film strip is a continuous plastic film strip of the production process, which is subdivided into the shipping bag segments at a later date. Said time is preferably coincident with the welding of the side edges. Preferably, it is a method for producing the shipping bag according to the invention, as described in the patent claims and the description.

Also, the invention relates to the use of a mailer according to one of the preceding claims, for the transport of goods to be shipped, in particular shipping the online trade.

With the invention described above, the aforementioned disadvantages of bags with handle holes can be avoided. The provision of shipping bags according to the invention with grip hole weakening zones for the formation of grip holes provides a clear added value not only for a mail order carrier or delivery courier, but also for the manufacturer of such bags. With the present invention is effectively prevents the shipping bag from slipping so that dropping the goods is unlikely. Also, wearing on the handle hole is usually more pleasant for the delivery courier. This is particularly important if the delivery courier has to carry transport bags very frequently due to their job. Thus, by providing grip holes accessible from grip hole weakening zones, occupational diseases such as back pain can be prevented. Despite the Grifflochschwächungszonen or the resulting handle holes, the sealing of the goods receiving area to moisture is not adversely affected. The tensile strength of the grip holes is increased compared to conventional shipping bags. It is also of particular advantage that the proportion of rejects in the production can be significantly reduced with the shipping bags according to the invention. It is believed that this is due to the fact that no incomplete punching process of the handle hole can give rise to production interruptions. Also grip hole edges are avoided, so that an intervention in the grip holes during production can be avoided. In addition, air movements can no longer cause the bag section, in which the grip hole is provided, inflates in parts and thus leads to production stoppages. Furthermore, the mail order company using the shipping bags according to the invention or the mail order company using this bag are also accompanied by increased process reliability. For example, the filling and / or transport, in particular the transport on conveyor belts, are much less prone to error.

schematic front views of an embodiment of the shipping bag, wherein a) the open bag with a first opening, b) the closed bag and c) the formation of a second opening is shown;

FIG. 1 a) and b) show various embodiments of the upper half 1 of the shipping bag, wherein each of the bag front wall 2 and an opposite at the upper bag end 12 slightly longer bag back wall 3 is visible. The upper half 1 of the shipping bag has an upper bag end 12, a first bag edge 4 and a second bag edge 5. In the said embodiments, the upper edge 10 of the bag front wall is lower than the upper edge 11 of the bag rear wall. The closable opening lies between said upper edges 10 and 11. The first side edge 6 of the bag front wall 2 abuts the first side edge 8 of the bag back wall 3, the latter being slightly longer towards the upper bag end 12. The second side edge 7 of the bag front wall 2 abuts against the second side edge 9 of the bag rear wall 3, the latter being slightly longer in the direction of the upper bag end 12. The first bag section 16 is also shown.

The second bag section is not visible since it is arranged on the lower half of the shipping bag (cf. FIG. 2 a) to c) ).

The embodiment of the FIG. 1 a) shows an embodiment of the upper half 1 of the shipping bag with two adhesive strips 14 and 15 as fastening means. Between the said adhesive strips 14 and 15, a destructible line 13 in the form of a weakening line (here a perforation line) is provided. The line 13 can be severed, for example, by means of a pair of scissors. The destruction of the line 13 also destroys the area between the adhesive strips 14 and 15 in the sense of the invention.

The embodiment of the FIG. 1 b) shows the top half 1 of the shipping bag with only one adhesive strip 15 as a fastener. In addition, the side edges of the bag rear wall 3 are bevelled in the region above the upper edge 10, so that side edges 8 and 9 are not linear over the entire length of the bag. This may be advantageous since the side edges 8 and 9 of the bag rear wall 3 can not protrude laterally in the area above the upper edge 10.

FIG. 2 a) and b) show various embodiments of the lower half 17 of the shipping bag, wherein each of the bag front wall 2 is visible. The shipping bag has a lower bag end 19, a first bag edge 4 and a second bag edge 5. The bag rear wall is completely covered by the bag front wall 2 and is therefore not visible in the schematic front view. The bag front wall 2 has the first side edge 6 and the second side edge 7. The shipping bag will be in a first Bag section 16 and a second bag section 18 divided. The second bag section 18 is delimited in each case by a first weld 22 from the first bag section 16 in the embodiments. The first weld connects the bag front wall 2 and bag back wall. In the exemplary embodiments, in the first bag section 16 between the bag front wall and the bag rear wall, the at least one goods receiving area of the mailer bag. The second bag section 18 has a grip hole weakening zone 20. Said grip hole weakening zone is formed by corresponding weakening regions, for example in the form of perforation lines 21 in the bag front wall and bag rear wall. At the bottom of the bag 19, the bag has a simple folding edge 23 (V-fold).

FIG. 2 a) shows an embodiment in which the first weld 22 extends linearly from the first bag end 4 to the second bag end 5. The grip hole weakening zone 20 can be found at the lower end of the bag 19 in something centrally between the first weld 22 and the folded edge 23.

FIG. 2 b) shows an embodiment in which the first weld 22 has a curvature, so that the Grifflochschwächungszone 20 is surrounded by this three directions. The location of the Grifflochschwächungszone corresponds largely to the location in FIG. 2 a) , The connection points 32 of the weld are located in FIG. 2 b) at the lower edge of the bag front wall.

FIG. 3 a) shows an embodiment of the unlocked shipping bag. Said embodiment can be from the upper half according to FIG. 1 a) and the sub-half substantially according to FIG. 2 a) form. In addition, a stripe pattern was printed. The numbering of FIGS. 3 a) to c) takes place analogously to FIG. 1 a) and FIG. 2 a) , Based on said figures, the principle of operation of the closure with two parallel adhesive strips will be explained. The bag can be closed with the adhesive strip 15 by removing the foil strip of the adhesive strip 15 and folding said region above the upper edge 8 of the bag back wall 3 onto the bag front wall 2 so that the adhesive strip 15 adheres to the bag front wall 2.

The bag sealed in this way is in FIG. 3 b) played. The folding of the bag rear wall 3 on the bag front wall 2 was carried out along the folding edge 24. On the bag rear wall 3, the destructible line 13 is reproduced. It is present around a perforation line, so that it can be seen on both visible sides of the bag rear wall 3.

As in FIG. 3 c) however, it is now possible to open the shipping bag, although the adhesive strip 15 binds irreversibly by destroying the area along the destructible line 13. Thus, a new opening is created along the perforation line. The area of the bag rear wall, which lies between destructible line 13 and top edge 11, remains resting on the bag front wall.

This opening can be closed again by the area of the bag back wall 3 is folded with the adhesive strip 14 forward on the bag front wall 2 and sealed with the adhesive strip 14. Thus, despite the irreversible sticking with the adhesive strips 14 and 15, the embodiment has a possibility of once opening and resealing the bag. The re-sealed bag visually corresponds largely to the bag FIG. 3 b) In this case, the destructible line 13 would be a destroyed line 13. In contrast to the grip hole weakening zone according to FIGS. 2a) and 2b ) the weakening line 21 is not continuous. Rather, in the Grifflochschwächungsbereich a portion 28 is provided which has no perforation and thus leads to the fact that after reaching through the Grifflochschwächungszone the grip hole covering portion is not completely detached from the bag, but remains connected to this over the section 28. In this way it can be avoided that the environment is contaminated with the handle hole concealing portions 30.

It is clear to the person skilled in the art that even more adhesive strips are conceivable, as a result of which a repeated opening and closing is possible. Such embodiments, with adhesive strips that are interrupted by destructible foil areas, are particularly preferred.

The features of the invention or their combination for the realization of the invention in its various embodiments can be taken from the following claims.
