- the stopping device 23 is in the figures provided as a wing at the tightening element 21.
- the wing which is shown in detail in Fig. 6f, may be provided by bending or folding an area 31 of the tightening element 21 , wherein, subsequently, the bended or folded area is attached to the tightening element 21 through a plastic weld 32 or through another means of attachment, such as gluing, seam etc.
- the wing 31 is engaged against the opening 26 in the channel 22 and prevents the tightening element 21 from sliding further back into the channel 22.
- An alternative stopping device 23 is shown in Fig. 6a.
- the stopping device 23 is provided using a stiffened area 33.
- the stiffened area 33 is provided using several inclined seams in the tightening element 21 , which makes this area of the tightening device 33 stiffer than the rest of the tightening element 21 , which prevents the stiffened area 33 from returning into the channel 22 after having been pulled out of the channel 22.
- An alternative stopping device 23 is shown in Fig. 6b; here, the stopping device 23 is provided as two spaced apart seams 34a, 34bg transverse to the tightening element 21, and this will have a corresponding function to the stopping device 23 in Fig. 6a.
- An alternative stopping device 23 is shown in Fig. 6c: here, the stopping device 23 is provided having two spaced apart seams 35a, 35b formed as two arrows or angles transverse to the tightening element 23.
- FIG. 6d and 6e An alternative stopping device 23 is shown in Fig. 6d and 6e.
- the stopping device 23 is formed as a double wing with two projecting elements 31a, 31b from the stopping device 21, wherein the stopping device 21 first is folded as in Fig. 6e and then is merged together by a plastic seam or plastic weld 32 as in Fig. 6d. Again, the wings 31a, 31b will engage against the opening 26 in the channel 22 and prevent the tightening element 21 from further sliding back into the channel 22.
- the stopping device may then be provided as an area of the tightening device which comprises an extension which prevents the tightening device from entering into the channel again after being pulled out, or the stopping device may cause friction against the channel 22 and in the same way prevent the tightening device from entering back into the channel again after being pulled out.
- the friction may be provided by a structure or surface as mentioned above, or by the stopping device being formed from one or more materials which will provide friction against the channel 22 and which thus keep the bag closed.
- the stopping device 23 is generally provided by using the material of the tightening element 21 itself, in addition to attachment means such as glue/seam etc.
- Fig' s 7a-e The pulling direction for pulling the tightening element 21 out of the channel 22 is shown by arrow T.
- the stopping device 23 is provided by an extra material 41 being attached to the tightening element 21.
- the extra material 41 is preferably formed such that it slides easily out of the opening 26 of the channel 22, but is prevented from sliding back into the opening again. As shown, the extra material 41 is formed with a sliding face 41a and a barb 41b.
- the stopping device 23 is provided by removing parts of the tightening element 21.
- the tightening element 21 is here made from a thicker material, wherein a wedge shaped recess 42 is provided on both sides of the tightening element 21 by removing parts of the tightening element 21.
- Fig. 7c corresponds substantially to Fig. 7b.
- the stopping device 23 in the form of the wedge shaped recess 42 is only provided on one side of the tightening element 21.
