Definitions

  • the invention relates to a closure clip made of elastically adjusted plastic for closing foil bags for packaging and the like. with two clamping arms pivotally connected to each other in the area of each of their ends, which are provided in the area of their respective other ends with locking elements which can be brought into releasable connection engagement.
  • closure clips are used to close the usual packaging bags made of plastic film in such a way that the packaging material contained in the bag is accessible for removal after opening the closure clip, but the bag can also be closed again if only partially emptied.
  • the bag is gathered in the area of its opening and - possibly - slightly rotated, whereupon the closure clip with the unlocked and opened clamping arms is guided over the twisted bag opening area and then closed by pressure on the opened end areas of the clamping arms.
  • the invention has for its object to form closure clips of this type so that they have a tight and firm, i.e. Ensure closure of bags of different sizes secured against unwanted removal from the bag, the clips being able to be opened and closed without difficulty — if necessary also several times.
  • clamping arms each have a leg section which is spaced and essentially parallel in the closed position of the locking clip, and that of the other clamping arm leg section facing flat side of at least one of the clamping arms projects a clamping projection, the height of which is measured by the associated leg section is selected so that the clear distance between the leg sections in the closed position is at least largely bridged by the clamping projection or the clamping projections.
  • a bag closed with such a closure clip is thus clamped of the gathered bag mouth area between the clamping lugs or - if only such a clamping lug is provided - compressed between the clamping lug and the second clamping arm, a clamping force being exerted on the bag mouth area due to the spring-elastic deformation of the clamping arms that occurs, so that a tight and tight closure is given.
  • the configuration can be such that a clamping projection emerges from the flat side of a leg section, the height of which is approximately equal to the clear distance between the leg sections of the clamping arms located in the closed position.
  • at least one clamping projection can protrude from the flat side of the clamping arm leg sections, the height of which is then in each case dimensioned approximately half the clear distance between the clamping arm leg sections.
  • the respective clamping lug assigned to a swivel region can also be divided into at least two - or more - clamping sections by at least one cut made from the free clamping edge of the respective clamping lug essentially up to the flat side of the respective leg section.
  • This facilitates an outwardly bulging bending of the clamping arms, which is particularly useful when a relatively large bag is to be closed, i.e. the gathered and - possibly - twisted mouth region of the packaging bag is relatively thick.
  • the incision or incisions expediently have a configuration which tapers in a V-shape in the direction of the flat side of the associated clamping arm leg section. This ensures that the clamping arms can bulge outwards without the clamping arm sections hindering this curvature in that the surfaces delimiting the incisions come into contact with one another prematurely.
  • the two clamping arms are suitably pivotally connected by a film hinge.
  • the locking elements are in an advantageous development the invention of in the vicinity of the free ends of the clamping arms formed by their strip-like approaches which face the other clamping arm facing the flat side, the free edges of which are folded in opposite directions in a hook-like manner.
  • the hook-like folds formed in this way can therefore be locked together.
  • a strip-like handle provided as a release lever is molded onto the strip-like approach which is folded over on its free edge in the manner of a hook in the direction of the pivoting connection of the clamping arms, the free edge of which points away from the pivotable connection of the clamping arms.
  • the clear distance existing in the closed position between the clamping arms - and largely bridged by the clamping attachment or the clamping attachments - is determined in an expedient development by the length of a spaced portion angled from the shaft section of one of the clamping arms, with - if necessary - the film hinge at the end of this Spacer section connects to the shaft section of the other clamping arm.
  • the closure clip shown in FIGS. 1 and 2, designated in its entirety by 10, is a one-piece injection molded part made of an elastically adjusted plastic, which is shown in FIG. 1 in the open state and in FIG. 2 in the closed position.
  • the closure clip 10 has two clamping arms 14 and 16, which are pivotally connected to one another via a film hinge 12, of which the clamping arm 14 is formed by an elongated, essentially rectangular shaft section 18, from the flat side of which, in the closed position, faces the other clamping arm 16 rib-like clamping projection 20 protrudes.
  • a spacing section 24 is angled from the clamping arm 16 at the lower end of the swivel section 22 corresponding to the leg section 18 of the clamping arm 14.
  • the film hinge 12 connects the free end of this spacer section 24 to the shaft section 18 of the clamping arm 14.
  • the height of the clamping projection 20 measured at right angles to the flat side of the shaft section 18 corresponds approximately to the length of the spacer section 24 or is only slightly smaller.
  • each clamping arm 14, 16 a strip-like extension 26, 28 running in the transverse direction, each of which has an opposite hook-like edge 30, 32 at its free ends.
  • the length of the lugs 26, 28, measured at right angles from the flat sides of the shaft sections 18, 22 of the clamping arms 16, is selected such that the folds 30, 32 in the closed position illustrated in FIG. 2, in which the shaft sections 18, 22 run approximately parallel , are hooked together, ie are in latching engagement and thus prevent the clamping arms 14, 16 from pivoting apart into the open position shown in FIG. 1.
  • a transverse handle 34 protrudes from the upper flat side of the strip-like extension 26, which acts as an entra lever serves. If pressure is applied to the free end of this release lever 34 and the projecting upper end of the shaft section 18 of the clamping arm 14 with the thumb and the index finger, the strip-shaped extension 26 bends elastically in such a way that the fold 30 formed at its free end comes out of the locking engagement with the edge 32 and the clamping arms can then be pivoted apart, for which the person operating the locking clip 10 pulls the upper free end of the clamping arm 16 away from the clamping arm 14 with the second hand.
  • the closure clip 110 shown in FIGS. 3 and 4 largely corresponds to the closure clip 10 described above, so that it suffices to describe only the modifications made in detail below, while for the corresponding design features refer to the preceding description of FIGS. 1 and 2, especially since the same parts of the two locking clips in the drawing figures are assigned the same reference numerals, which, however, in the case of the locking clip 110 are preceded by a "1" to distinguish them from the locking clip 10.
  • each clamping approaches 120a or 120b occur at half the height, which are dimensioned to be more solid in width than the rib-like clamping projection 20, but instead by one led from the free clamping edge of the respective clamping projection 120a, 120b essentially to the flat side of the respective leg section 118, 122, the V-shaped tapered incision 121 is divided into two clamping attachment portions 121a, 121b.
  • a further modification of the locking clip 110 is that the shaft section 122 still protrudes downward beyond the right-angled spacing section 124 and thus forms a handle 123, which opens the clip 110 after it has been released by pressing on the handle 134 and the upper one free edge of the shaft portion 122 facilitated.
