Description

The present invention relates to a plastic shipping bag, in particular an on-line plastic shipping bag, Furthermore, the invention relates to the use of such a plastic shipping bag for transporting goods to be shipped, in particular of shipping the online trade.

Conventional plastic shipping bags are well known in the art. For example, this describes WO 91/15406 A1 a security bag with a tab on its back with adhesive to close the security bag.

Laid-open specification 2 061 582 relates to a method for the production of block bags with a central bottom opening. The central floor opening is used in vacuum cleaner bags.

The DE 1 170 861 relates to a sack or bag made of paper with a cross or folding bottom, wherein the overlapping parts of the bottom flaps leak laterally in tear tabs. These allow the sack to open.

The DE 1 882 441 U1 relates to a packaging for consumer goods, which is designed as a carrier bag. In this case, the top is closed, while the bottom is open ("bottomless"). Sheath parts can be used to close the bottom after introduction of the goods.

Another example of a resealable plastic bag with a bottom fold is in the US2007 / 0062161 shown. Plastic shipping bags are regularly used in online mail order. It is not uncommon for the ordered goods to be returned for a variety of reasons, for example due to defects. In order to enable a cost-effective and simple handling of returns, the same bags are and are often reused by a customer with whom the goods were sent. For a safe return shipping these bags must be filled by the customer after opening and removal of the goods again with the same and sealed for the return transport. The opening of such bags by a customer should preferably be such that a subsequent reclosure of the bag readily succeeds reliably. Advantageously, recourse is made to those plastic shipping bags, which can be opened without additional aids after first closing without problems. In the same way, the plastic bags should be able to be resealed reliably and unproblematically for a return shipment, so that the goods are safely present in the shipping bag during transport, in particular without having to resort to additional resources for this reclosure. Numerous closure systems for bag openings of such plastic bags are known from the prior art. Obviously, the focus here was on the design of suitable plastic shipping bags on the bag opening.

So far, the returned in the manner described to the dealer or manufacturer goods out of destroying the plastic shipping bag out of this. The film webs used for such plastic shipping bags become increasingly stable, in particular more tear-resistant, and that although the film systems used are becoming increasingly thinner at the same time. It is also possible with the adhesive materials used to bring about a very firm connection between the opening closing plastic film web and the adjacent plastic film material. Not infrequently, therefore, a very large amount of force is required to tear the film closure or film material. Alternatively or additionally, one resorts to the use of knives or scissors to get back the returned goods. This also leads to damage to the returned goods. It would therefore be desirable to be able to resort to plastic shipping bags, which are not affected by the described shortcomings.

Therefore, the present invention was based on the object to provide plastic bags available that allow a simple and reliable way to remove shipped or returned goods from the plastic shipping bag, without running the risk of damaging the goods.

The object of the present invention is achieved by a plastic shipping bag, comprising a bag front wall and an opposite bag rear wall, each with upper edge, lower edge and first and second side edge, a closable bag opening, an opposite bag bottom with a bottom fold and a first bottom fold portion extending from the lower edge the bag front wall extends to the bottom fold, and a second bottom fold section extending from the bottom edge of the bag back wall to the bottom fold, the bag front wall and the bag back wall along or adjacent their respective first and second side edges to form first and second elongate connection areas, respectively first and second connecting strips or lines, connected to each other, in particular welded, are, from the transition from the first bag fold portion to the bag front wall, in particular from the Unt at least one, in particular elongated, first, second, third and fourth weakening area, in particular at least one first, second, third and fourth perforation line, at least in sections adjacent to and spaced from the first elongated connection area in the direction of the bag opening in the bag front wall and the bag back wall and the first and second bottom fold section and wherein at least one elongate further attenuation area, in particular a further perforation, of the, in particular elongate, first, second , third and / or fourth weakening area, preferably substantially orthogonal, extending in the direction of the second elongate connection area.

The present invention is accompanied by the surprising finding that openable plastic shipping bags can be obtained in a relatively simple manner, without, however, having to accept losses in the sealing of the contents and in the opening of the packaging. It has now surprisingly been found that the first, second, third and fourth weakening areas allow a particularly simple opening, wherein the shipping goods neither comes into contact with sharp objects, nor is exposed to excessive pressure. Weakening areas which are applied in the manner described above nevertheless make it possible to securely seal shipping goods in plastic shipping bags during transport, although the bag bottom is loaded in a generic manner during transport.

A plastic 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 usually closable, preferably so that no opening remains unlocked. The plastic shipping bag usually has at least one area, in particular interior space, for goods or shipping article receiving, which can essentially be completely closed and bounded by the front wall of the bag, the rear wall of the bag and the bottom of the bag. Bags that have non-closable bag openings that allow inadvertent dropping out of shipping items during transport are generally unsuitable as a shipping bag. It is basically conceivable to deform a plastic shipping bag so that a precise description of the geometry is no longer possible. The remainder of the description is therefore preceded by the fact that the description refers to an unfilled, undeformed state of the plastic shipping bag, wherein the plastic shipping bag is preferably to be considered substantially flat stretched out.
