DE10153420A1 - Post office plastic mail bag for placement in public mail boxes has air lock arrangement - Google Patents

Abstract

A post office mail box is fitted with a mail sack manufactured especially as a plastic web with perforated separation lines between individual sacks. The sack mouth dimensions match those of an adaptor installed within the mail box. The top of the mail sack has two or more finger grips. The inner face of the sack has a welded air lock flange which allows for insertion of mail without generating external air vortices.

Description

The anthrax letter problem has led to the need for mail to be as contamination-free as possible. By irradiating letters contamination can be reliably eliminated and thus the afterwards subsequent work steps and the recipient of the post are protected.

However, it is also necessary to change the workflow from posting a letter Secure post office or at the post box to the radiation unit. Like experiences have shown, contamination of uncontaminated letters and the Postal systems and processing machines.

According to the invention, these contaminations can be prevented by using the contamination-protecting mail bags can be prevented.

It is made of a resistant, airtight plastic material and so it is Shaped as a web of sacks connected by a perforated seam are separable, is manufactured. The bags are then unrolled individually from the roll and hung in the mailboxes or in appropriate hanging devices.

The sack according to the invention is completely closed and has a "mouthpiece" ( 3 ) which is pulled over the insertion opening of the mailbox. The opening in the inside of the mailbox is modified with a suitable attachment so that the attachment and "mouthpiece" fit exactly together. Above the mouthpiece, a locking tab ( 2 ) is welded to the edge of the mouthpiece and fixed with a removable adhesive. The flap is self-adhesive on the outside. The adhesive surface is protected by a protective film. The mouthpiece is glued airtight with the flap for transport.

The mailbag advantageously has one or more handles ( 1 ) above the mouthpiece, which are used for secure anchoring in the mailbox in hooks of the insertion attachment or the hanging device provided for this purpose. At the same time, they serve as secure handles so that the sack can be conveniently carried by hand in a conveyor.

A flap ( 4 ) is welded behind the mouthpiece, which ensures that the mailpieces slide in without air swirling and air exchange between the sack and the outside air. Advantageously, one or more openings are provided in the upper area, which are covered with a multi-layer particle filter ( 5 ). The filter has a robust, close-meshed protective film on the outside, so that it cannot be accidentally pressed in. The one or more particle filters are provided so that air can escape from the sack contamination-free in the closed state if it z. B. is stacked in the mail vehicle or in other transport devices.

Advantageously, one of the filters is designed as a passive collector for suspected contamination ( 5 ), so that it can be punched out after it is empty and forwarded for checking. Suitable predetermined breaking devices or weakenings are advantageously to be provided.

The use of the sack is as follows: A sack comes off the roll taken and hung in the open mailbox by the postal worker. Doing so the mouthpiece is pulled over the insert and hooked in. Then we will Box closed and the device is ready for use. Through the slot Thrown letters slide along the sack wall into the sack.

After opening the box, the sack is removed and the mouthpiece ( 3 ) is glued to the closing flap ( 2 ) attached above. The sack can then be moved as usual and fed to the radiation system or another suitable letter processing system. For this purpose, the sack is cut open in the encapsulated area at the lower end, emptied and welded flat again. The passive collector is punched out and the punched hole is also welded or glued. In this way, the empty bags can be disposed of properly.

Suitable labeling fields or other coding options must also be provided, e.g. B. with one or more transponders, magnetic strips, chips etc., in order to be able to trace the path of the mail bag. It is ideal to attach these coding tools to the passive collector ( 5 ) so that the information and the sample can be handled together.
