Abstract
Abstract The invention relates to plastic pockets to be applied to parcels and the like and intended to contain address labels, packing lists and the like, and which are provided with an adhesive on one side to be applied to the parcel. According to the invention, the plastic pockets are formed from two plastic films which are welded together with a bottom weld (1) and two lateral welds (2, 3), which do not reach up to the openings of the pockets so that a section (5) is formed where the films are not welded together. The pockets are applied to a protective paper in the form of a continuous web and are separated by perforations (6) which only penetrate the plastic films but not the protective paper. The invention also relates to a device for dispensing plastic pockets according to the above and comprising a holder (10) for a roll (11) of a web of a number of plastic pockets on a continuous protective paper and means (14) for opening the pockets for introduction of dispatch notes and/or other communications. In a preferred embodiment the feed of the web of pockets is driven and is controlled by sensor means (13) so that the opening is correctly carried out.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
146 words
Plastic pockets provided with an adhesive on one side and a protective paper over the adhesive, said pockets being intended to be applied to parcels and other packets after insertion of dispatch notes and/ or other communications in the pockets and removal from the protective paper, and arranged in the form of a continuous web, characterized in that they are formed of two plastic films which are welded together by means of a bottom weld (1) and two lateral welds (2, 3), which do not extend up to the openings of the pockets, so that a part (S) is formed where the films are not welded together, said pockets being separated by means of perforations (6), which only pass through the plastic films but not through the protective paper and that the openings (4) of the pockets are arranged in the longitudinal direction of the web.
Claim 2
Dependent Claim
146 words
Plastic pockets provided with an adhesive on one side and a protective paper over the adhesive, said pockets being intended to be applied to parcels and other packets after insertion of dispatch notes and/ or other communications in the pockets and removal from the protective paper, and arranged in the form of a continuous web, characterized in that they are formed of two plastic films which are welded together by means of a bottom weld (1) and two lateral welds (2, 3), which do not extend up to the openings of the pockets, so that a part (S) is formed where the films are not welded together, said pockets being separated by means of perforations (6), which only pass through the plastic films but not through the protective paper and that the openings (4) of the pockets are arranged in the longitudinal direction of the web.
Claim 3
Dependent Claim
44 words
Plastic pockets according to claim 1, characterized in that the perforation (6) is made such that two adjacent pockets are connected at least partly on the part of the perforation corresponding to the part (5), where the two plastic films are not welded together.
Claim 4
Dependent Claim
34 words
Plastic pockets according to claim 1 or 2, characterized in that they are completely cut from each other down to the protective paper except for a small part (8) close to the opening (4).
Claim 5
Dependent Claim
35 words
Plastic pockets according to any of claims 1-3, characterized in that the upper plastic film is somewhat longer than the lower plastic film at the opening (4) of the pockets and forms a flap (9).
Claim 6
Dependent Claim
40 words
S. Plastic pocket according to any of claims 1-4, characterized in that at the bottom of each pocket, the upper film is longer than the lower film and the protective paper so that it extends to a holding flap (7).
Claim 7
Dependent Claim
22 words
Plastic pockets according to any of claims 1-5, characterized in that they are rolled to a roll together with the protective paper.
Claim 8
Independent Claim
68 words
A device for dispensing plastic pockets according to any of claims 1-6, characterized in that it comprises a holder (10) for a roll (11) of a web of a number of plastic pockets on a continuous protective paper and means (14) for opening the pockets for introducing dispatch notes and/or other communications, and optionally also a tearing edge (18) for the protective paper after separation from the pockets.
Claim 9
Dependent Claim
142 words
The device according to claim 7, characterized in that it also comprises a breaker roller (12), over which the web of protective paper with plastic pockets is running, sensor means (13) for sensing the position of the pockets, a breaker roller (15) at which the protective paper (18) is separated from the pockets, a driven device for feeding forward the protective paper and a driven support roller (16) for feeding forward the plastic pockets separated from the protective paper, the drive means of the support roller (16) giving this roller a peripheral speed such that a pulling force is applied to the separated pockets, said force being sufficiently high to separate the pockets from the protective paper, and that starting and stopping the pulling of the protective paper and the pockets separated therefrom is controlled by signals from the sensor means (13).
Claim 10
Dependent Claim
53 words
The device according to claim 8, characterized in that the roll (11) is braked and that the sensor means (13) controls the pulling operation such that it stops when a pocket is opened by the opening means (14) and is situated before said means, after which the pullinp operation can be restarted manually.
Claim 11
Independent Claim
69 words
The device according to any of claims 7-9, characterized in that the opening means (14) is arranged such that it holds down the lower film and the protective paper but lifts the upper film so that the pocket is opened, whereby it is only in contact with the upper film at the edge of the pocket being opened, or only parts of the upper film associated with adjacent pockets.
