Definitions

  • This invention relates to apparatus for applying a deformable sealing clip around the mouth of a flexible container such as a sausage casing, plastic bag, and the like. More particularly the invention is directed to a generally U-shaped deformable sealing clip somewhat similar to that shown in US. Pat. No. 3,400,433 and the present invention may be considered to be an improvement over said patent insofar as the clip disclosed herein be adaptable for use with plastic film having greater than normal resistance to deformation.
  • a clip particularly adapted to provide an effective seal by applying a strong radially inwardly directed sealing force to the material of the container and at the same time provide protection against crushing such material to an extent causing the material to fail, thereby destroying it for its intended purpose.
  • the present invention is directed to a solution of this particular problem involving plastic materials having more than normal resistance to deformation.
  • the main object of the present invention is therefore the provision of a U-shaped clip of novel cross section which is formed to provide optimum resistance to the radially outwardly directed forces exerted by the plastic material and at the same time exert sufficient inwardly directed forces to deform such high strength materials to the point at which an airtight seal may be effected without causing failure of the material.
  • FIG. 1 is a semischematic side view showing a clip of the present invention with the associated punch and die at the point at which the legs of the clip are about to be deformed inwardly toward each other.
  • FIG. 2 is a cross sectional view through the sealed material showing the clip in its final deformed condition.
  • FIG. 3 is a fragmentary side elevation of a sausage casing showing the clip applied thereto.
  • FIG. 4 is an enlarged cross section through the clip.
  • the clip generally designated 10 is adapted to be urged against a die A by a punch B in order to deform the clip around the neck C of the container to be sealed.
  • the undeformed clip 10 comprises a pair of opposed legs 11, 12 which are connected together at one of their corresponding ends by a crown 13 joined to said legs by curved junctures 14 and 15.
  • the legs 11, 12 are straight and may be considered parallel except that it is preferable that they flair outwardly slightly at their free ends to facilitate controlled feeding of the clip along the feed track (not shown).
  • the crown piece 15 is straight and may be considered perpendicular to the axes of legs 11, 12.
  • the junctures 14, 15 are formed to a relatively sharp radius but one that is sufficiently large so as not to distort the wire excessively during the bending operation of forming the clip.
  • the clip may be formed of various materials including steel and aluminum and it is preferably cold-worked to the shape shown in FIG. 1.
  • the cross sectional shape of the clip 10 shown in FIG. 4 is generally semicircular along its inner article engaging side and is generally trapezoidal along its outer side.
  • the inner article engaging side of the clip is provided with a central flat portion F to which the arcuate portions R constituting the remainder of the inner side are tangent.
  • the centers of curvature of the portions R are spaced apart the slight distance F to provide the central flat portion of the article engaging side.
  • the outer portion of the clip is generally trapezoidal and is formed to provide a flat outwardly directed face A which is adapted to receive any desired imprinting which may be applied to the same.
  • the inner side of the trapezoidal section has a width W and is spaced outwardly from the arcuate portions R by a relatively narrow flat section G.
  • the function of the flat inwardly directed portion F is to reduce the otherwise excessive localized bearing forces which would result if the inner section were exactly semicircular in shape. It will be understood in this connection that such a circular inwardly directed inner section would present essentially line contact at the central portion of the clip which would have a severe cutting effect on the material to be sealed.
  • the flat section F By making the flat section F of a width about /8 the entire width W of the clip such excessively high localized pressures are reduced to a point that a cutting effect is obviated.
  • extremely high pressures are nevertheless obtained at the central portion of the clip in view of the fact that the portions R diverge away from such central portion thus causing high radially inwardly directed pressure to be applied to the material at said central portion.
  • the outer portions of the arcuate sections R nevertheless cause sealing forces to be applied along substantially the entire width W even though said sealing forces at said outer portions may be considerably less in intensity than those applied to the central portion of the article engaging side.
  • the outer trapezoidal section is employed to obtain optimum section modulus for the amount of material used so as to resist the high radially outwardly directed forces applied on the closed clip by the sealed material.
  • the section modulus of the outer trapezoidal portion is twice that of a semicircle if the wire were made round and of a radius equal to the average radius of the inner portion of the clip defined by arcuate sections R and the flat portion F.
  • the provision of the outer trapezoidal section in effect increases the section modulus by at least 50% over that of a corresponding round wire of a radius approximating R.
  • the outer flat face A permits imprinting thereon and the outwardly converging side walls of the trapezoidal portion facilitate feeding the clip along the clip track. Additional improvement of the section modulus of the clip is obtained by moving the trapezoidal portion outwardly from the centers of curvature of the sections R by the relatively small amount indicated at G.
  • a clip of the shape shown in FIG. 4 having a depth D and width W should have a flat section F of a width approximately /8 of the width W.
  • the offset G between the substantially circular inner portion and the outer trapezoidal portion need not be more than about of the depth D.
  • the width A of the outwardly directed flat face is preferably slightly larger than one half the width W.
  • the total depth D of the clip is about 25% greater than the width W.
  • a fastener for forming a tight seal around an article such as the mouth of a flexible container comprising:
  • an initially generally U-shaped clip having a pair of opposed legs and a crown connecting corresponding ends of said legs
  • said legs being adapted to be deformed toward each other and into encircling relation with such article
  • said clip being formed of wire of generally uniform cross section throughout its length and being shaped in cross section to provide a substantially semicircular article engaging inner side and a pair of opposite sides converting outwardly of said clip from said inner side.
  • a fastener according to claim 1 wherein the outer portion of said clip is substantially trapezoidal in cross section with a flat outer side equal in Width to about one half the depth of said clip.
