Definitions

  • ABSTRACT A can capable of being folded into a definite form by [211 Appl' 406790 hand, the can including two parts.
  • the can has parallel grooves or beads spaced from the top to bottom ends Foreign Application Pri it D t on the cylindrical sides of the can.
  • Japan 47-103195 P or bottom fmm ring Strips mund the 3 Four d1v1der grooves or beads are spaced at equal lntervzils 52 us. 01. 220/1 R; 215/1 c can R ring Strip? [51] Int. Cl.
  • the present invention relates to an empty can capable of being folded by hand and more particularly, a can in which the outer or inner surface of a cylindrical can is provided with grooves for folding this can by hand when it is empty.
  • empty cans cause a bottleneck for transportation because of their very bulky volumes.
  • Empty cans may be deformed by pressure,-however, cans are manufactured so strongly that they may not be bent without using special tools, resulting in leaving them as empty cans. If empty cans are folded by hand without using any special tool, not only will the user voluntarily treat used cans but social pressure will force persons to fold the cans.
  • the object of the present invention is to provide a can which can be easily treated after use.
  • Another object of the present invention is to provide a can which can be folded easily into a definite predetermined form by hand when it is empty.
  • a still further object of the present invention is to provide a can, the volume of which can be minimized greatly when it is empty.
  • Another object of the present invention is to provide a can, whereby the cleaning of surroundings and the improved recovery of material are attained with a reduced cost for transporting waste materials.
  • Still another object of the present invention is to provide a two part aluminium can which can be folded into a definite form by hand.
  • a can which is capable of being folded into a definitefform by hand.
  • the can has two parts and comprises parallel grooves or beads spaced from the top and bottom ends of the sides of the can forming ring strips in the soft metal can.
  • Four divider grooves or beads are spaced at equal intervals around the can and are perpendicular to the ring strips on the side of the said can.
  • Diagonal grooves are formed on each quadrilateral formed by said divider grooves or beads and the grooves or beads which form said rings.
  • Short grooves are provided along the circumference of the can at each middle point of said divider grooves or beads perpendicular thereto.
  • a can according to the present invention when a can is empty it can be folded perfectly into a definite form by hand without using any special tool. Persons can carry it back easily from mountains, beaches, or streets. In recycling of the empty cans for resources after collecting them, the transport capacity necessary is reduced to one-fourth, so that the can according to the present invention has further advantages compared with the transport of the conventional cans which virtually transports air due to the larger volume of the cans.
  • FIG. 1 is a perspective view of a can according to the present invention.
  • FIG. 2 is a developed view of the cylindrical can.
  • FIG. 3 is a side view which shows the can in a pressed state.
  • FIG. 4 is a cross-section] view before pressing on IV--IV line in FIG. 3.
  • FIG. 5 is a cross-sectional view after pressing on IVIV line in FIG. 3.
  • FIG. 6 is a side view which illustrates the angle with respect to the horizontal direction.
  • FIG. 7 is a side view after folding.
  • the present invention will be illustrated in detail with reference to the drawings.
  • the example for illustration is an aluminium can which holds 350 ml. of beer.
  • the diameter of D is 65 mm and the length of L is mm.
  • This can comprises cylindrical portion 1 and top 2, shaped together with the bottom by the impressing method.
  • the can is made of a soft metal such as aluminium and an alloy of aluminium.
  • FIG. 2 is a developed view of the side of the cylindrical can 1 as shown in FIG. 1.
  • Ring strips 5 and 6 are formed by making the grooves or beads 3 and 4 parallel to the edges at an interval from the top and bottom ends on the outside or the inside of the side.
  • the interval, that is the width of the ring strips 5 and 6 is for example about 515 mm, about 10 mm is desirable, by making the notched lines or beads 7 and 8 parallel to the grooves 3 and 4.
  • the spacing between adjacent ring strips should be less than the diameter D, taking into consideration the fold discussed below. Therefore, though the non-broken zone 9 is not always neceasary for a can within this range, one non-broken zone 9 would be necessary for above-mentioned beer cans and two would be necessary for taller cans.
  • four divider grooves or beads 10, ll, 12 and 13 are made between rings 5 and 6 or between the rings 5 or 6 and non-broken zone 9 spaced at equal intervals of n-D/4.
  • the diagonal notched lines 14 and 15 are made on each quadrilateral A, B, C and D formed by the grooves or beads 10, ll, 12 and 13.
  • short horizontal grooves 16, l7, l8 and 19 with a length of about one-eighth of the circumference, n'D/S being desirable, are crossed on the middle point of the four divided grooves or beads 10, l 1, l2 and 13.
  • the above-mentioned grooves or beads can be made on either the inside or the outside of the side. In the present invention many grooves are made on thin and soft metal as mentioned above, so that it is desirable to strengthen the inside or the outside of the center non-broken zone with a bead (the swelling line).
  • Each of the above-mentioned grooves or beads correspond to a folding line which promotes movement by finger-pressure.
  • the way to fold the can in the present invention is as follows. Pressure is applied with ones fingers to each central point of each quadrilateral A and C, that is the intersecting point 20 of grooves 14 and 15. The side of the can 1 caves into the position of symmetry in the inside direction as shown by the broken line.
  • the finger pressure is applied to each center point of each quadrilateral B and D in the same way, the can has eight symmetrical cavities. Crossing these cavities at the level of the cross grooves 16, 17, 18 and 19, the shape shown in FIG. 4 changes into that shown in FIG. 5.
  • the points l0, 11, 12 and 13 seen in FIG. are not the points in fact but the acute-angled pillars which extend up and down the can 1, except in the ring strips 5 and 6 and the center non-broken zone 9.
  • An important point in folding the can is the reduction of the strength of the pillars. This is done by folding in the same direction, either right or left, on the crossed grooves16, 17,18, and 19 as shown in FIG. 6.
  • the way to fold the can is first to join fingers around the tops of the acute angle 10, 11,12 and 13, shown in FIG. 5 and then to press them in the same horizontal direction.
  • the pillars with an acute angle change into two thicknesses of folded material as shown in FIG. 6.
  • the can is then twisted by holding the ring 5 or 6 and the nonbroken zone. Though the acute and straight pillar are strong, two thicknesses of folded material are fragile.
  • the empty can without pillars formed by the fold lines which are turned to the inside is just before broken, so that when pressure is applied to it the shape of it changes as shown in FIG. 7 and folding into a definite form is perfected. Therefore the thickness of the can after folding becomes 20-30 mm, less than a quarter of the original length.
  • a beer can treats as an embodiment but the can according to the present invention is not only limited to the beer can but can also be used for various kinds of cans.
  • the form of cylindrical can is not limited to a circle but an ellipse or other shape can be used.
  • the can in the present invention comprises soft metal such as aluminium including a special ferro-alloy in which the grooves or beads 3 and 4 are made at intervals from the top and bottom ends on the side of a cylindrical can.
  • the can has the advantage that in folding the can the middle portion is folded easily, keeping the original shape in this portion.
  • the line of the fold is put inside in this portion so that it has the advantage that after folding the can only a portion remains as shown in FIG. 7 and the size of the can is reduced to under a quarter of its original size.
  • a cylindrical can capable of being folded into a predetermined shape by hand, said can comprising parallel first grooves spaced from the top and bottom ends of the can wherein ring strips are formed on the side of said can between said first grooves and the top and bottom of said can, at least one pair of spaced second grooves, parallel to said first grooves and positioned therebetween, a plurality of third grooves spaced at equal intervals around said can and running between each said first groove and an adjacent said second groove perpendicular thereto wherein the space formed between said second grooves in each said pair of second grooves has no third grooves therein, diagonal grooves extending between the corners in the quadrilateral formed by said first, second and third grooves, and short grooves formed along the circumference of the cylinder at each mid-point of each said third grooves, perpendicular thereto.
  • a can according to claim 1, wherein the length of the short grooves made along the circumference is about one-eighth of the circumference.
