Abstract

Abstract Coherent bands (1) of suction tubes (2) wrapped in individual protective envelopes are used to make possible the mechanical and automatic application of suction tubes to individual packing containers. The bands consist of two strips (7) of flexible plastic material which are sealed to one another and between them enclose the suction tubes. To facilitate the separation of the suction tubes and surrounding protective envelopes from the band on application to the packing containers, the suction tube band is provided in accordance with the invention with transverse cuts (6) situated between the suction tubes which at their ends lead into further cuts which extend in longitudinal direction of the band or have a certain length in the said direction. The individual protective envelopes entering into the suction tube band are thus held together solely by two parts situated at a distance from one another and extending bandlike between the envelopes which can be cut through comparatively simply on application to the individual packing containers.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 65 words
Flexible band with transversely applied suction tubes, characterized in that the band (1) is provided between two suction tubes (2) with a transverse cutting line (6) which at some distance inside the longitudinal edges (3, 4) of the band meets cuts (8) which, seen in longitudinal direction of the band (1) take up a many times greater extent than the said transverse cuting line (6).
Claim 2
Dependent Claim 65 words
Flexible band with transversely applied suction tubes, characterized in that the band (1) is provided between two suction tubes (2) with a transverse cutting line (6) which at some distance inside the longitudinal edges (3, 4) of the band meets cuts (8) which, seen in longitudinal direction of the band (1) take up a many times greater extent than the said transverse cuting line (6).
Claim 3
Dependent Claim 26 words
Flexible band in accordance with claim 1, characterized in that the cuts (8) are linear and extend substantially at right angles to the cutting line (6).
Claim 4
Dependent Claim 23 words

Claim 5
Dependent Claim 17 words
Flexible band in accordance with claim 3, characterized in that the cuts are constituted by circles (9).
Claim 6
Dependent Claim 18 words
