Definitions

  • the invention relates to a closure clip made of elastically adjusted plastic for closing foil bags for packaging and the like.
  • a closure clip made of elastically adjusted plastic for closing foil bags for packaging and the like.
  • two clamp arms pivotally connected to each other in the area of each of their ends, which are provided in the area of their respective other end with latching elements which can be brought into releasable connection engagement, the clamp arms each having a spaced and essentially parallel leg section in the closed position of the closure clip have, from the flat side facing the other clamping arm leg section, a strip-like clamping projection projects in each case.
  • closure clips serve 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 is also possible if only partially emptied can be closed again.
  • the bag is gathered in the area of its open side in such a way that the film material of the bag is folded onto one another several times in the opening area so that the width of the opening area is smaller than the length of the clamping arms of the closing clip.
  • the closure clip is then guided with the unlocked and opened clamping arms over the folded-up bag opening area and closed by pressure on the opened end areas of the clamping arms.
  • This closure clip has proven itself for small to medium-sized foil bags up to a certain size.
  • the invention has for its object to form closure clips of this type so that they have a tight and firm, i.e. Secure closure of bags of different sizes, in particular also of larger bags with a high filling volume, against unintentional removal from the bag, the clips being able to be opened and closed without difficulty — if necessary also several times.
  • this object is achieved according to the invention in that the height of the clamping lugs is approximately equal to half the clear distance between the clamping arm leg sections, and in that the clamping lug assigned to each leg section is provided by at least one of the free ones Clamping edge of the respective clamping attachment is divided into at least two clamping attachment sections, which are made essentially up to the flat side of the respective leg section and which are opposite one another when the clip is closed.
  • the subdivision of the clamping lugs into a plurality of clamping sections enables the clamping arms to bend outwards, which is particularly advantageous when a relatively large bag is to be closed. The mouth area of such large bags can then simply be closed by twisting. Due to the possibility of elastic bending of the clamping arms, such a relatively thick, twisted mouth region can also be clamped between the clamping arms.
  • 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 portion. 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 latching elements are formed by near the free ends of the clamping arms of their strip-like approaches, which face the other flat arm facing the respective clamping arm, the free edges of which are folded back in the manner of hooks. The hook-like folds thus formed can thus be locked together.
  • a strip-like handle provided as a release lever is molded onto the strip-like approach which is folded over at its free edge in the direction of the pivot connection of the clamping arms, the free edge of which points away from the pivotable connection of the clamping arms.
  • the clear distance between the clamping arms in the closed position - and largely bridged by the clamping lug or the clamping lugs - is determined in an expedient development by the length of a spaced section angled from the shaft section of one of the clamping arms, with - if necessary - the film hinge 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 110, 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 locking clip 110 has two clamping arms 114 and 116 which are pivotally connected to one another via a film hinge 112, of which the clamping arm 114 is formed by an elongated, essentially rectangular shaft section 118, from the flat side of which, in the closed position, faces the other clamping arm 116 rib-like clamping projection 120a protrudes, while a clamping projection 120b protrudes from the shaft section 122 of the clamping arm 116.
  • a spacing section 124 is angled from the clamping arm 116 at the lower end of the shaft section 122 corresponding to the leg section 118 of the clamping arm 114.
  • the film hinge 112 connects the free end of this spacer section 124 to the shaft section 118 of the clamping arm 114.
  • the height of the clamping projection 120a measured at right angles to the flat side of the shaft section 118 corresponds approximately to half the length of the spacer section 124 or is only slightly smaller. The same applies to the height of the clamping lug 120b.
  • each clamping arm 114, 116 a strip-like extension 126, 128 runs in the transverse direction, each of which has an opposite hook-like edge 130, 132 at its free ends.
  • the length of the lugs 126, 128, measured at right angles from the flat sides of the shaft sections 118, 122 of the clamping arms 114, 116, is selected such that the folds 130, 132 in the closed position illustrated in FIG. 2, in which the shaft sections 118, 122 approximately run parallel, are hooked together, ie are in latching engagement and thus prevent the clamping arms 114, 116 from pivoting apart into the open position shown in FIG. 1.
  • a transverse handle 134 protrudes from the upper flat side of the strip-like extension 126 and serves as a release lever.
  • this release lever 134 When pressure is applied to the free end of this release lever 134 and the projecting upper end of the shaft section 118 of the clamping arm 114 with the thumb and the index finger, the strip-shaped projection 126 bends elastically such that the fold 130 formed at its free end comes out of the locking engagement with the edge 132 and the clamping arms can then be swung apart, for which the person operating the locking clip 110 pulls the upper free end of the clamping arm 116 away from the clamping arm 114 with the second hand.
  • the half-height of the clamping lugs 120a and 120b, which essentially bridge halfway between the closed clamping arms 114, 116, are subdivided into two clamping lug sections 121a, 121b and 121a ', 121b' by V-shaped tapering cuts 121.
  • Such an elastic curvature of the shaft sections 118, 122 is not impeded by the aforementioned V-shape of the incisions 121.
  • the shaft section 122 of the locking clip 110 is extended downward beyond the right-angled spacer section 124 and thus forms a handle 123 which facilitates the opening of the clip 110 after it has been released by pressure on the handle 134 and the upper free edge of the shaft section 122 .
