Description

  The present invention is a metal open pail can widely used as a container with a canopy for liquid products such as fuel oil, lubricating oil, paint, ink, solvent, adhesive, edible oil, etc., and in particular, the so-called T-shaped can body shrinks downward. It relates to the open pail can having a diameter.

  Conventionally, as an open pail can made of metal such as tin, tin-free steel, stainless steel, etc., a lag type open pail can P11 as shown in FIG. 8 (a) and a band type as shown in FIG. 8 (b). Open pail can P12 is widely used. In the former lug type, the can lid 2A is fastened and fixed to the opening edge of the can body 1 by a large number of lugs 21 provided on the periphery, whereas in the latter band type, the can lid 2B is tightened with a U-shaped cross section. Although there is a difference that the can body 1 is fixed to the opening edge of the can body 1 by tightening with the band 5, the can body 1 has a substantially common form in both types, and the vine-shaped handle 3 is attached to the upper portion. In general, the lug type can lid 2A is provided with a spout 22 as shown.

  In general, both types of can bodies 1 have a disk-shaped ground plate 12 fixed to a lower end of a body portion 11 obtained by bending a metal plate into a cylindrical shape and seam-welding the ends. The upper edge of the body 11 has two upper and lower parts that bulge outward along the circumferential direction, while the peripheral edge of the opening forms a curled part [reference numeral 13 in FIG. 9B]. The annular bead portions 11a and 11b are formed. A hat-shaped handle mounting bracket 4 referred to as an ear is fixed to each of the slightly lower radial sides of the upper annular bead portion 11a by spot welding or the like. The vine handle 3 is attached to the can body 1 so as to be vertically rotatable by inserting both end hook portions 31a of the wire material 31 curved in a substantially semicircular arc shape into the handle mounting bracket 4 respectively. A cylindrical grip 32 made of wood or plastic is fitted in the middle part (Patent Document 1).

  On the other hand, in such an open pail can, as shown in the figure, the barrel 11 of the can body 1 is reduced in diameter as a T type (tapered pail type), and the barrel 11 as an S type (straight pail type). Some do not change in diameter up and down. In the former T-shaped open pail can, when transporting and storing in an empty state, the can body 1 and the can lids 2A and 2B can be stacked separately to reduce the overall volume and increase the space efficiency. There is an advantage. As shown in FIGS. 9 (a) and 9 (b), the can bodies 1 are stacked in a nested manner by utilizing the fact that the body portion 11 is reduced in diameter downward. The lower annular bead portion 11b in the main body 1 is placed on the curled portion 13 at the peripheral edge of the opening in the lower can main body 1.

JP2011-148520A (FIGS. 5 and 6)

  However, in the conventional T-type open pail cans P11 and P12, even if the can bodies 1 are stacked in a nested manner as shown in FIG. In order to reduce the transportation cost per number, it is desired to lower the bulk of the stacked state. Therefore, if the lower open bead 11b of the can body 1 in the conventional T-shaped open pail cans P11 and P12 is omitted, an improved open pail can P13 is formed, and the can bodies 1 are stacked in a nested manner as shown in FIG. a) As shown in (b), the handle mounting brackets 4 on both sides of the upper can body 1 are placed on the curled portion 13 at the peripheral edge of the opening in the lower can body 1, and the stacking height is reduced accordingly. It will be. In this case, for example, it is possible to stack 12 cans as shown in FIG. 10 (a) with the stacking height approximately equivalent to that of the conventional 8 cans shown in FIG. 9 (a). Since the number of stacked cans in Japan increases by about 50%, the transportation cost per number of cans can be greatly reduced compared to the conventional case, and the space efficiency during storage can be greatly improved.

  However, in the improved open pail can P13 of the above-described improved product, when the can bodies 1 are stacked in a nested manner, the weight of the cans can be sequentially increased from the upper side to the curled portion 13 of the lower can body 1 via the handle fittings 4 on both sides. Therefore, the lower can body 1 whose load weight increases, the dent deformation tends to occur at the contact position of the handle fitting 4 in the curled portion 13. Also, during the stacking operation, there is a concern that the curl portion 13 may be dented or scratched by the handle mounting bracket 4 of the upper can body 1 striking the curl portion 13 of the lower can body 1. When the can main body 1 having a dent or a flaw is used for such a curled portion 13, even if the liquid product is accommodated and the can lids 2A and 2B (see FIG. 8) are attached, the sealing is incomplete, and the conveyance is performed. Liquid leakage will occur during handling.

  In view of the above-described circumstances, the present invention is a T-shaped metal open pail can that can be stacked in a cantilever manner in an empty state, and can significantly reduce the bulk of the stacked state as compared to conventional products. It is an object of the present invention to provide a device that can prevent the occurrence of dents and scratches due to the stacking load and the impact at the time of stacking.

  If means for achieving the above object is shown with reference numerals in the drawings, the invention according to claim 1 is that the cap-shaped handle mounting bracket 4 is provided on the open side on the both radial sides of the upper part of the outer peripheral surface of the can body 1. The metal open pail cans P1 and P2 are fixedly welded at the peripheral edges of the vine-shaped handle 3 and the hook portions 31a at both ends of the vine-shaped handle 3 are respectively inserted and locked in insertion holes 41 provided on the top surface of the handle mounting bracket 4. The can body 1 forms a curled portion 13 in which the opening periphery of the upper end is wound outward, the diameter of the lower side is reduced downward from at least the fixing position of the handle mounting bracket 4, and the lower side is along the circumferential direction. And a gap t is formed between the lower end portion of the handle mounting bracket 4 and the outer peripheral surface of the can body 1, and the buffer cover portion 51 has a locking protrusion 52, Buffer member 5 made of synthetic resin or synthetic rubber molded product integrally formed with 53 The buffer cover 51 is engaged so as to cover the lower surface side of the handle mounting bracket 4 by inserting the locking protrusions 52 and 53 into the handle mounting bracket 4 from the gap t. Yes.

  According to the second aspect of the present invention, in the metal open pail cans P1 and P2 of the first aspect, the can body 1 bulges outward along the circumferential direction above the position where the handle mounting bracket 4 is fixed. An annular bead portion 11a is provided.

  According to a third aspect of the present invention, in the metal open pail can of the first or second aspect, the buffer member 5 has a band plate shape in which the buffer cover portion 51 is curved, and the locking protrusions 52 and 53 are the buffer cover. It is assumed that it is formed so as to rise from the central portion of one side edge of the portion 51 to the curved concave side.

  Next, effects of the present invention will be described with reference numerals in the drawings. First, in the metal open pail cans P1 and P2 according to the first aspect of the invention, when the can bodies 1 are stacked in a nested manner in an empty state, the can weights are sequentially passed through the handle attachment brackets 4 on both sides in order from the upper side. Although the load is applied to the curled portion 13 of the lower can body 1, the buffer cover portion 51 of the buffer member 5 is interposed between the lower surface side of each handle mounting bracket 4 and the curled portion 13. In addition to preventing deformation, it is possible to prevent dents and scratches caused by the handle mounting bracket 4 directly hitting the curled portion 13 of the lower can body 1 during the stacking operation.

  According to the invention of claim 2, since the can body 1 has the annular bead portion 11a on the upper side of the fixing position of the handle mounting bracket 4, the strength as a tubular body is improved by the reinforcing action. Since this annular bead portion 11a is located between the curl portion 13 at the upper end and the handle mounting bracket 4, it is exposed to the outside without coming into contact with the others in the nested stacked state of the can bodies 1 with each other.

  According to the third aspect of the present invention, the buffer member 5 is formed such that the locking protrusions 52 and 53 are raised from the central part of the edge on one side of the buffer cover 51 in the shape of a curved band plate to the curved concave side. Therefore, the engagement protrusions 52 and 53 can be easily mounted simply by being inserted into the gap t between the lower end portion of the handle mounting bracket 4 and the outer peripheral surface of the can body 1, and the buffer cover portion 51 is attached to the handle. Since it is arranged along the lower surface side of the metal fitting 4, even if the upper can body is dropped into the lower can body 1 inside the lower can body 1 at the time of stacking, the handle mounting bracket 4 directly curls the lower can body 1 There is no concern of hitting the portion 13, and there is an advantage that the occurrence of a dent or scratch on the curled portion 13 can be more reliably prevented.

  Hereinafter, embodiments of a metal open pail can according to the present invention will be specifically described with reference to the drawings. In the embodiment, the same reference numerals are given to the portions common to the above-described conventional and improved open pail cans even if the shapes and sizes are different.

  FIG. 1A shows the can body 1 of the 25L-type open pail can P1 according to the present invention, and FIG. 1B shows the can body 1 of the 12L-type open pail can P2. These can bodies 1 are formed by bending a metal plate such as tin, tin-free steel, stainless steel or the like into a cylindrical shape and seam-welding the ends to each other. The base plate 12 is wound and fixed. The opening periphery of the can body 1 forms a curled portion 13 that wraps outward, and hat-shaped handle mounting brackets 4 for attaching the vine-shaped handle 3 are spotted on both radial positions on the upper side of the trunk portion 11. One annular bead portion 11a that is fixed by welding or the like and bulges outward in the circumferential direction is formed above the fixing position of the handle mounting bracket 4, but is different from the conventional product. On the lower side of the fixing position, the same annular bead portion is not provided, and a buffer member 5 made of a synthetic resin or a synthetic rubber molding is mounted on the lower surface side of each handle mounting bracket 4. In addition, this can main body 1 is diameter-reduced below the annular bead part 11a of the trunk | drum 11 as the above-mentioned T type (taper pail type).

  As shown in FIGS. 2 (a) and 2 (b), the handle mounting bracket 4 has a welding flange 4b that protrudes to the left and right outside from the open edge of the substantially circular cup portion 4a, and is provided at the center of the cup portion 4a. A circular insertion hole 41 is provided, and spot welded portions 42 and 42 in the form of flanges are provided at two upper and lower portions of each welding flange 4b. Moreover, although the upper and lower sides of the open edge of the cup part 4a form a concave arc shape along the circumferential surface of the trunk part 11 of the can body 1, the central concave arc part 43 having a larger curvature has the effect of FIG. Between the outer peripheral surface of the trunk | drum 11 shown with the virtual line of b), the substantially crescent-shaped clearance gap t is comprised.

  As shown in FIG. 3, the buffer member 5 includes a curved strip-shaped buffer cover portion 51, and a locking protrusion 52 formed so as to rise from the center of one side edge to the curved concave side. The locking protrusion 52 has a triangular pointed tip, and is triangular with respect to a gap t formed between the bottom of the handle mounting bracket 4 and the body 11 of the can body 1. The width and thickness excluding the front end side of the shape are set to a size that cannot be slightly inserted. And as this buffer member 5 shows by the elasticity of the synthetic resin or rubber material, as shown by the arrow of Fig.1 (a) (b), the latching protrusion piece 52 is a handle attachment metal fitting from this clearance gap t. By forcibly inserting into the inner side of 4, the buffer cover portion 51 is engaged so as to cover the lower surface side of the cup portion 4a of the handle mounting bracket 4 as shown in FIGS. The thickness of the buffer cover portion 51 of the buffer member 5 is set to about 0.5 to 3 mm.

  As in the conventional product, the vine-shaped handle 3 has a cylindrical grip 32 made of wood or plastic fitted in the middle part of a wire material 31 curved in a substantially semicircular arc shape. As shown in b), the hook portions 31a, 31a at both ends of the wire material 31 are respectively inserted into the insertion holes 41 of the handle mounting bracket 4 so that the wire body 31 can be attached to the can body 1 so as to be vertically rotatable. Yes. Although not shown in the figure, the can body 1 of these open pail cans P1 and P2 is fitted with the same can lid (reference numerals 2A and 2B shown in FIG. 8) as a lug type or a band type. Is done.

  In the open pail cans P1 and P2 configured as described above, the can body 1 and the can lid are stacked separately when transported and stored in an empty state, but the can body 1 has a T shape (taper pail shape) and the body portion 11 faces downward. Since it has a reduced diameter, it will be stacked up and down. In the nested stacking of the can bodies 1, as exemplified as the improved product described above, an annular bead that bulges outward on the lower side of the fixing position of the handle mounting bracket 4 in the can body 1. Since there is no portion, the handle mounting brackets 4 on both sides of the upper can body 1 are placed on the curled portion 13 of the lower can body 1 so that the weight of the cans can be increased sequentially from the upper side. The curl portion 13 of the lower can body 1 is loaded via However, as shown in FIG. 5, a band plate-like buffer of the buffer member 5 is provided between the both side handle mounting brackets 4, 4 of the upper can body 1 and the curled portion 13 of the lower can body 1. Since the cover part 51 is interposed, the dent deformation of the curled part 13 is prevented, and each handle mounting bracket 4 does not directly hit the curled part 13 of the lower can body 1 during the stacking operation. Occurrence of dents and scratches in the curled portion 13 due to the hitting is prevented.

  Further, in the stacked state of the can bodies 1 shown in FIG. 6, the buffer cover of the buffer member 5 is compared with the stacked state of the can bodies 1 shown in FIG. 10B of the improved open pail can P13 described above. Although the stacking height increases by the thickness of the portion 51, the thickness of the buffer cover portion 51 is as thin as about 0.5 to 3 mm, so that, for example, even when 20 cans are stacked, it is only a few cm higher than the stacked state of the improved product. Just not a big difference. Therefore, even in the can bodies 1 of these open pail cans P1 and P2, for example, the number of stacked cans in the same height space is increased by about 50% compared to the conventional stacked state shown in FIG. The transportation cost per number of cans can be greatly reduced, and the space efficiency during storage can be greatly improved.

  As the buffer member 5 used in the present invention, ones having various shapes of the buffer cover portion 51 and the locking projection piece 52 can be adopted. For example, the buffer cover portion 51 is short so as to cover a part of the lower surface side of the handle mounting bracket 4. A flat plate may be used. However, as in the buffer member 5 illustrated in FIG. 3, in the form in which the locking protrusion 52 rises toward the curved concave side from the center of one side edge of the curved strip-shaped buffer cover 51, the locking protrusion Since the piece 52 can be easily attached only by being inserted into the gap t, and the buffer cover portion 51 is disposed along the lower surface side of the cup portion 4a of the handle mounting bracket 4, the lower can body 1 Even if the upper can body is dropped in a slightly inclined position, there is no concern that the handle mounting bracket 4 directly hits the curled portion 13 of the lower can body 1, and the curling portion 13 has a dent or scratch. There is an advantage that can be prevented more reliably.

  Since the buffer member 5 itself is extremely lightweight, the handle mounting bracket 4 is forced by the frictional force at the insertion portion by forcibly inserting the locking protrusion 52 of the form illustrated in FIG. 3 into the gap t. It is self-held so that it will not fall out. However, the locking projection piece may have a bifurcated shape in order to more surely prevent the dropout. For example, in the buffer member 5 illustrated in FIG. 6, the bifurcated locking protrusions 53, 53 open toward the curved concave side from the central portion of the one side edge of the curved strip-shaped buffer cover portion 51. In this state, both the locking protrusions 53 and 53 cannot be inserted into the gap t because the opening width is large. However, the buffer cover 51 is strengthened as shown in the phantom line in the figure. The dimensions are set so that the front side widths of both locking projections 53, 53 are narrowed and can be inserted into the gap t by being deformed so that both locking projections 53, 53 are closed. By releasing it after the insertion, as shown in FIG. 7, both the locking projections 53, 53 are restored to the open state by the material elasticity, and cannot be removed from the gap t.

  Moreover, if it is set as the structure which has the annular bead part 11a on the upper side rather than the adhering position of the handle attachment metal fitting 4 in the can main body 1 like the open pail cans P1 and P2 exemplified as the embodiment, the annular bead part 11a There is an advantage that the strength as a tubular body is improved by the reinforcing action. Further, in the embodiment, the trunk portion 11 of the can body 1 is reduced in diameter downward below the annular bead portion 11a, but at least the lower side than the fixing position of the handle mounting bracket 4 may be reduced in diameter. The entire body part 11 below the curled part 13 may be reduced in diameter downward. In addition, since the annular bead part 11a is located between the curl part 13 at the upper end and the handle mounting bracket 4, it will be exposed to the outside without being in contact with the other in the nested stacked state between the can bodies 1. .

  In addition, in the present invention, the capacity of the metal open pail can, the bent shape of the hook portion 31a of the vine-shaped handle 3, the shape and welding position of the cup portion 4a and the welding flange 4b of the handle mounting bracket 4, and the clearance t In addition to the embodiment, various design changes can be made to the detailed configuration such as the shape and the distance between the curled portion 13 and the handle mounting bracket 4.
