1453331 Pliers for closing clips on packages H NIEDECKER 4 Jan 1974 [10 Jan 1973 (2) 11 April 1973] 00435/74 Heading B4W Pliers for applying a U-shaped clip 9, described and claimed in Specification 1,453,332 (see Division E2) to a gathered portion 12 of a packaging material and for closing the clip therearound comprises pivoted arms 1, 2 a housing member 5 integral with one of the arms 1, a plate 6 pivotally mounted on the housing member 5 and having a recess 8 for holding a clip 9 with its open end towards the gathered material 12 when the latter is disposed adjacent a die 19 mounted on the housing member, and a drive connection between the arm 2 and the plate 6 for pivotal movement thereof whereby the clip is made to move in an arcuate path 18 firstly to embrace the gathered portion 12 and then to be closed by the action of the die 19 and plate about the said portion 12. A pivoted spring-loaded lever 13 assists in the correct placing of the gathered material adjacent the die 19. A magazine for supplying the clips extends laterally from the housing member (Fig. 3, not shown). As shown the drive connection includes an extension of the arm 2 and a cam groove 29 in the plate 6 but in an alternative embodiment (Figs. 1-3, not shown) the connection involves a knee type lever. In another embodiment (Fig. 6, not shown) a tapered opening in the housing member provides a lead-in for the gathered material to a space adjacent the die.

Description

Clip for closing packaging envelopes HERBERT 46234 The invention relates to a closure clip for pliers closing Such a device is described in copending Israel 43807 file December In accordance with an aspect of the present invention there is provided for use in the present device a closure clip adapted to be closed about a gathered portion of a wrapping wherein the clip is substantially having a first arm and a second arm joined by an arcuate the first and second arms being intended to be bent towards one another to engage and close about the gathered portion of wrapping and wherein the first arm is curved in the direction in which that arm of the clip is intended to be closed and the second arm is curved in the same direction as the first thereby being in the opposite direction to that in which that second arm of the clip is intended to be the ends of the arms being bent slightly towards one The arms conveniently correspond to circular extending approximately which in turn correspond to the boundary of the circular arcuate clip guide The arms are furthermore conveniently of unequal the more sharply curved arm being the It is thereby ensured that the arms strike the die simultaneously at the end of the circular arcuate clip Lastly it is convenient to bend the ends of the arms slightly in order to ensure that both arms reliably strike the a slighter exertion of force is necessary for the closure by this and the arms commence to roll more readily when they strike the thereby obviating The present clip is particularly suitable for use with the present pliers closure device with a circular arcuate clip guide because it makes possible a reliable p the arm which is curved the opposite direction to the direction exhibits a stronger closing force than straight arm or than the outer am which is curved in the closure as said inner arm exhibits a greater force against the static return forc the tendency of the closed gather to open a of the clip for an equal closing force is rendered or else a stronger and reliable closure is achieved for the Wires of various profiles be used for the present In order to enable the invention to be reference will now be made to the accompanying drawings which and by way of example some and in Flgure 1 shows a closure clip for use with the closure pliers shown in the aforementioned Israel patent application and Figures 2 and 3 show the closure clip in a closed In each of the embodiments described in the mentioned Israel patent the clip 9 is adapted to the circula arcuate clip guide path in that both arms 31 and 32 of They and a punch The more sharply curved inner clip arm 32 is shorter than the outer arm in order that the arms strike the die 19 The ends 33 of the are bent inwards in order to facilitate the closure while the 34 is which means th packaging gather is best Figures 2 and 3 shew the clips in the in which the clip have been guided past one They have been applied to the circumferenc of the gather to a greater or lesser degree depending upon the thickness of the insufficientOCRQuality

Claims (5)

1. A closure clip adapted to be closed about a gathered portion of a wrapping material, wherein the clip is substantially O-shaped having a first arm and a second arm joined by an arcuate web, the irst and second arms being intended to be bent towards one another to engage and close about the gathered portion of wrapping material, and wherein the first arm is curved in the direction in which that arm of the clip is intended to be closed and the second arm is curved in the same direction as the first arm* thereby being curved in the opposite direction to that in which that second arm of the clip is intended to be closed, the ends of the arms being bent slightly toward one another.

2. A closure elip as claimed in claim , wherein the arms lie along axes of approximately concentric circles.

3. A closure clip as claimed in claim 1 or 2 wherein the arms are unequal in length, the second arm being a more sharply curved arm and shorter than the first arm*

4. A closure clip as claimed in any one of claims I to 3, wherein the web connecting the arms is approximately semicircular.

5. A closure clip according to any of the preceding claims substantially as hereinbefore described with reference to the accompanying drawings. For the Applicants DR. NHOLD COH AND PARTNERS PC/mm
