Definitions

  • the present invention relates to an improved process for tying bags, and more particularly to a process for tying synthetic resin bags by the employment of novel tying mediums.
  • a prior art process for tying a synthetic resin bag comprises the steps of placing a U-shaped tying medium formed of circular section wire in to a first die member, inserting the constricted mouth portion of the bag between the legs of the tying medium, bending the legs of the tying medium inwardly toward each other by the first die member, and then compressing the legs from above by a second die member so as to firmly apply the tying medium around the bag mouth.
  • the tying medium has a circular cross section, the bag mouth is contacted and compressed by only the center portion of the curved inner surface of the tying medium. Therefore, if the bag has a large diameter mouth, even when a tying medium is applied around the bag mouth with a strong force, the tying force exerted by the tying medium is subjected to a limitation.
  • the area where the bag mouth contacts with the surface of the tying medium may be larger than in the case acircular cross section tving medium is employed for the same purpose. but when the flat tving medium is compressed from above, the legs of the tying medium tend to bend outwardly resulting inweaker tying strength as compared with the tying strength obtained by the circular cross section tying medium.
  • a die device which comprises an unper die member and a lower die member has to be modified so that the device may be suitable for particular sizes of the mediums.
  • the die device is modi- 4 fied so as to be suitable for particular sizes of tying mediums, uniform and sufficient tying effects cannot be obtained by the employment of such prior art tying mediums because of the above-mentioned disadvantages inherent to them.
  • the present invention is to provide an improved process for tying synthetic resin bags which can tie the bags satisfactorily while eliminating the above disadvantages inherent to the prior art processes referred to hereina-bove.
  • a length of wire material having a flat portion and the remaining arcuate portion both of which portions extend in the longitudinal direction thereof is employed for forming a tying medium and the wire material is bent into a U-shape configuration so as to dispose the flat portion inside.
  • the constricted mouth of a synthetic resin bag is inserted between the legs of the tying medium in such a manner that the constricted mouth of the bag is encircled by the tying medium and the fiat portion of the medium is forced to abut against the periphery of the 3,343,253 Patented Sept. 26, 1967 bag mouth with a strong compressive strength whereby the bag is firmly tied by the tying medium.
  • Another object of the present invention is to eliminate the necessity of modifying the die device even when various sizes of tying media are employed.
  • FIG. 1 is a perspective view of wire material useful for forming a tying medium which is to be employed for carrying out the process according to the present invention
  • FIG. 2 is a front elevational view of a die device comprising an upper die and a lower die useful for carrying out the novel process and which shows portions thereof in section;
  • FIG. 3 is a cross-sectional view of the mouth portion of a bag tied according to the novel process
  • FIG. 4 is a cross-sectional View taken along the line A-A of FIG. 3 and as seen in the arrow direction therein;
  • FIG. 5 is similar to FIG. 4, but shows the mouth portion of a bag around which a conventional round section tying medium is tied;
  • FIG. 6 is similar to FIG. 3, but shows the mouth portion of a bag around which a conventional flat type tying medium is tied.
  • the numeral 1 designates wire material having a flat portion 2 and the remaining arcuate section portion 3 both of which portions uniformly extend in the longitudinal direction of the wire material, and the material is suitable for forming a tying medium in carrying out the novel process of the present invention.
  • the width of the flat portion 2 is somewhat narrower than the major diameter of the arcuate section portion 3.
  • FIG. 2 shows a die device in which the wire material 1 is bent so as to form a tying medium and a synthetic resin bag is tied by the tying medium.
  • the die device comprises a lower vertically movable die member 4 and an upper stationary die member 9.
  • the lower die member 4 has a U-shaped recess 5 on the upper surface for receiving the wire material 1 and a pair of retractable opposite side pieces 6.
  • Each of the retractable side pieces 6 comprises upper and lower portions with a spring 7 disposed therebetween so that the upper portion of the respective retractable side piece is normally urged upwardly by the action of its spring 7 and projects above the upper surface of the body of the lower die member 4.
  • the projected portions of the side pieces 6 form an extension of the recess 5 on the upper surface of the body of the lower die member 4.
  • the numeral 8 designates a tying medium retaining plate which is adapted to abut against both legs of a U-shaped bent tying medium 11 when the same is formed by deforming the wire material 1 in the U- shape recess 5 and hold the tying medium 11 in position While the tying medium 11 is tied around the mouth portion of the bag in the manner of which explanation will be made hereinafter.
  • the stationary upper die member 9 has also a reversed U-shape recess 10 on the lower surface which faces the U-shape recess 5 of the lower die member 4.
  • the wire material 1 is bent in the recess 5 of the lower die member 4 so as to form a U- shape tying medium with the flat portion 2 disposed in side and thereafter the constricted mouth of a synthetic resin bag 12 is inserted between the legs of the tying medium 11.
  • the lower die member 4 is moved upwardly toward the upper stationary die member 9 until the tops of the side pieces 6 of the lower die member abut against the lower surface of the upper die member.
  • the side pieces 6 of the lower die member 4 are depressed down by the upper die member 9 and these side pieces are caused to gradually retreat against the action of their springs 7, and accordingly, the upper half portions of the legs of the tying medium 11 are first bent inwardly toward each other by sliding along the inclined side walls of the recess 10 in the upper die member 9 and then compressed by the bottom of the recess 10 whereby the substantially half portions of the legs of the tying medium 11 are deformed so as to form inwardly and outwardly projecting bulges as shown in FIG. 3 which firmly grip the mouth portion of the bag 12 with a strong force.
  • the tying force obtained by the employment of the flat type tying medium is less than that ohtainable by the employment of the circular section tying medium.
  • the present invention can eliminate the above disadvantages inherent to the prior art processes are referred to above.
  • the tying medium 11 has a sufficiently thick arcuate section portion in spite of the fact that the flat portion is formed therein, even when the medium is compressed by the die device it is assured that the upper half portions of the legs are bulged inwardly, but not outwardly, whereby the tying medium can apply a strong tying force against the bag.
  • Wire material 1 for the tying medium 11 is not limited to that shown in FIG. 1, but wire materials having various contours may be employed within the scope of the spirit of the present invention as far as such wire materials have flat portions with suitable widths and the remaining portions with thicknesses sufficient enough to assure formation of inwardly projecting bulges when they are compressed.
  • a tying medium to be employed for tying the bag should satisfy the following requirements:
  • a tying medium for tying such a bag should have a relatively great modulus of section.
  • a tying medium should have such a c oss-section configuration that the tying medium may contact a bag at a relatively large area and distribute its tying force uniformly over the whole contact area of the bag.
  • novel tying medium to be employed in carrying out the process of the present invention is advantageous in the fact that the same possesses both a great modulus of section which a round section tying medium has and a wide contact surface which a fiat type tying medium has.
  • a process for tying a bag comprising the steps of bending a length of circular cross-section wire material having a fiat portion extending in the longitudinal direction of said wire and a thickness substantially equal to the width of said flat portion so as to form a U-shaped tying medium with the flat portion facing inside, inserting the constricted mouth of a bag between the legs of said U-shaped tying medium and against said flat portion thereof, and compressing said tying medium so as to firmly apply the upper half portions of said legs around the bag mouth and into end abutting relationship whereby inwardly extending bulges may be formed on said portions of the legs and the flat portion thereof is in gripping relationship with said constricted mouth of the bag.
