Closure clip having a plurality of spikes
A closure clip is provided for closing tubular or bag-shaped packaging for bulk produce such as fruit or vegetables. The closure clip includes a first arm and a second arm extending substantially in a plane and aligned at least approximately parallel to each other, with the arms each having first and second ends and a base portion extending in the center plane defined by the arms and having an inner and an outer surface, with the base portion connecting the first and second arms at their first ends and forming an approximately U-shaped closure clip. The closure clip further includes a first spike having a first end and a second end, extending from the inner surface of the base portion between the arms and parallel thereto, and connected with its first end to the base portion. The closure clip further has at least one second spike having first and second ends.
1. A closure clip for closing tubular or bag-shaped packaging for bulk produce such as fruit or vegetables, comprising:
two arms forming a first and second arm extending substantially in a plane and aligned at least approximately parallel to each other, said arms having first and second ends;
a base portion extending in the centre plane defined by the arms and having an inner and an outer surface, said base portion connecting the first and second arms at their first ends and forming an approximately U-shaped closure clip;
a first spike having a first end and a second end, extending from the inner surface of the base portion between the arms and parallel thereto, and connected with its first end to the base portion, wherein the length of the first spike is at least equal to a dimension of the cross-section of at least one of the arms; and,
at least one second spike having first and second ends, which extends from the inner surface of the base portion between one of the arms and the first spike and parallel thereto and is connected with its first end to the base portion, wherein the length of the second spike is shorter than the length of the first spike,
wherein the length of the first spike is sized so that the first spike extends with its second end into a gap between the arms when the closure clip is shifted to a closed configuration thereof, in which the closure clip is bent around the tubular or bag-shaped packaging to be closed and in which the arms lie approximately parallel to each other at least in sections, wherein the second end of the first arm faces towards the first end of the second arm and the second end of the second arm faces towards the first end of the first arm.
2. The closure clip according to claim 1 , further comprising:
a third spike having first and second ends, which extends from the inner surface of the base portion between the other one of the arms and the first spike and parallel thereto and is connected with its first end to the base portion, wherein the length of the third spike is shorter than the length of the first spike.
3. The closure clip according to claim 1 , where the length of the first spike is a multiple of a dimension of the cross-section of at least one of the arms.
4. The closure clip according to claim 1 , where the cross-section of the first spike tapers towards its second end.
5. The closure clip according to claim 1 , where the second and third spikes are arranged at a distance from and parallel to the centre plane defined by the arms.
6. The closure clip according to claim 5 , where the second and third spikes are arranged on different sides of the plane defined by the arms.
7. The closure clip according to claim 6 , where the second and/or third spike is arranged on the same side of the plane defined by the arms.
8. The closure clip according to claim 1 , where the cross-section of the second and/or third spike tapers towards the second end.
9. The closure clip according to claim 1 , where the first spike and/or the second and third spikes end in a sharp point at their second ends.
10. The closure clip according to claim 1 , where a cam is arranged on the outer surface of the base portion.
