The projection part (the bead 23) is formed in a manner that the lower end is positioned below the lower end of the ear part 4, and on the projection part (the bead 23), a circumventing part 24 is formed to circumvent the ear part 4 to be arranged above the ear part in the vicinity of the ear part 4.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a tapered pail container (pail can) having a handle for carrying and capable of being stacked and transported, and more specifically, a reinforcing convex part such as a bead or a rib on a side wall which is a body part of the container. The present invention relates to a taper pail container with a convex portion formed by.

  Conventionally, as a container for storing and transporting contents such as liquids and fluids, a pail can which is a bucket-like container having a handle (handle) for carrying is known. In addition, among such pail cans, a plurality of pail cans are stacked one above the other in consideration of the transport efficiency when transporting only containers (cans) in an open state without a lid before contents are put. In order to enable stacking, a tapered pail can that is tapered such that the diameter of the side peripheral wall that becomes the body portion of the container (can) increases as it goes upward is also known. In order to emphasize that the taper pail is space-saving, it may be called a stacker type or a stacker pail can.

  In addition, not only metal pail cans such as steel and stainless steel but also resin (plastic) pail containers are known. And the taper pail container with a convex part by which convex part processes, such as a bead and a rib, were given in order to raise the intensity | strength of the side peripheral wall of a trunk | drum part according to the content is also known.

  As such a taper pail container with a convex portion, for example, in Patent Document 1, the applicant of the present application, is configured by seam welding the two peripheral end portions 28 of the steel plate 27 that is roll-formed into a cylindrical shape, A storage can in which a base plate is wound around a bottom of a can, and is formed in a curved fixed edge 11 that is wound and formed outside the opening located at the uppermost part, and is formed on the lower stage of the fixed edge 11 so as to protrude outward. The bead 12 in one storage can 1 that is further stacked from above is fixed to the bead 12 in the other storage can 1 that is received from the lower side, so that the bead 12 in the other storage can 1 is stacked up and down. The bead 12 is configured such that it can be stacked, and a bead 12 is disclosed which has a reduced amount of outward protrusion at least at the circumferential end portion 28 that is seam welded (Japanese Patent Application Laid-Open No. H10-228707). Claim 1 range of allowed claims, specification paragraphs [0016] - [0022], the drawings of FIG. 5, see FIG. 6, etc.).

  However, in the storage can described in Patent Document 1, generally, the ear part of the handle is welded to the intermediate height between the upper and lower two beads 12, and the pail cans are stacked up and down and stacked. Thus, when transporting in a limited space such as a container ship, the number of containers that can be stacked in a large number is small, resulting in poor loading efficiency, resulting in increased transportation costs.

  Further, Patent Document 2 discloses a metal open pail can, in which the can body 1 forms a curled portion 13 in which the opening periphery of the upper end winds outward, and at least the lower side is lower than the fixing position of the handle mounting bracket 4. The lower side thereof does not have the annular bead portion 11a bulging outward along the circumferential direction, and the gap t between the lower end portion of the handle mounting bracket 4 and the outer peripheral surface of the can body 1 The buffer member 5 made of a synthetic resin or a synthetic rubber molding in which the locking protrusions 52 and 53 are integrally formed on the buffer cover portion 51 is formed from the gap t to the inside of the handle mounting bracket 4. By inserting, the buffer cover portion 51 is engaged so as to cover the lower surface side of the handle mounting bracket 4, and the bulk of the stacked state can be greatly reduced as compared with the conventional product. It can prevent dents and scratches from hitting. Metal open pail cans P1 and P2 are disclosed (see claim 1 of patent document 2, paragraphs [0016] to [0025] of the specification, FIGS. 5 and 10 of the drawings, etc.) ).

  However, when the metal open pail cans described in Patent Document 2 are stacked in the vertical direction in order to increase the loading efficiency, the metal open pail cans are stacked in the ear part (the handle mounting bracket 4) welded to the container body (can body 1). Since the load of the pail can is supported, there is a problem that even if the buffer member 5 is interposed, the ear part (the handle mounting bracket 4) and the container body around the ear part may be deformed. .

  Moreover, in the metal open pail can described in Patent Document 2, since the ear part (the handle mounting bracket 4) is supported by two-point support in a seesaw state, the stacked pail cans are inclined during transportation. There is a possibility that the cargo may collapse, and there is also a problem that the pail can before use may be damaged. In addition, in the metal open pail can described in Patent Document 2, only one annular bead portion 11a for preventing deformation is provided in the vicinity of the upper end, so that also in transporting and filling the contents. There is a problem that the pail can may be damaged.

  In addition, in the entire container of the storage can described in Patent Document 1, it is conceivable to raise the mounting position of the ear part relatively and increase the loading efficiency when stacking up and down, but the position of the handle and the contents of the container There was a problem that the balance with the object was lost and the usability when filling and carrying the contents deteriorated. In addition, there is a possibility that the strength of the entire container may be reduced, and convexity processing such as beads is limited to the vicinity of the upper end, and deformation of the middle part in the vertical direction of the container side peripheral wall cannot be prevented efficiently. There was also a problem.

JP 2008-195417 A JP2015-113155A

  Therefore, the present invention has been devised in view of the above-described problems, and its object is to change the strength and usability of the container, and to collapse the cargo during transportation, the ear part, etc. It is an object of the present invention to provide a tapered pail container with a convex portion that can be stacked in the vertical direction to the limit to increase the loading efficiency without causing a possibility that a part of the container is damaged.

  A tapered pail container with a convex portion according to a first aspect of the present invention is a tapered pail container comprising a container body having a tapered side wall and a bottom plate, and a handle for carrying the container body. In order to prevent deformation, a belt-like convex portion is formed along the horizontal direction that protrudes outward such as a bead, and an ear portion that swingably supports the handle on the side wall is attached. The convex portion is formed such that the lower end thereof is positioned lower than the lower end of the ear portion, and the convex portion includes a bypass portion so as to bypass the ear portion in the vicinity of the ear portion. It is formed.

  The taper pail container with a convex portion according to a second aspect of the present invention is characterized in that, in the first aspect, the detour portion has a strip-shaped upper side portion along the horizontal direction and an oblique side portion inclined with respect to the upper side portion. .

  A tapered pail container with a convex portion according to a third aspect of the invention is a tapered pail container comprising a container body having a tapered side wall and a bottom plate, and a handle for carrying the container body. In order to prevent deformation, a belt-like convex portion is formed along the horizontal direction that protrudes outward such as a bead, and an ear portion that swingably supports the handle on the side wall is attached. The convex portion is formed such that the lower end thereof is positioned lower than the lower end of the ear portion, and the convex portion is not formed in the vicinity of the ear portion.

  According to a fourth aspect of the present invention, there is provided a tapered pail container according to any one of the first to third inventions, wherein the container body is made of steel.

  The taper pail container with a convex portion according to a fifth invention is characterized in that, in the fourth invention, the ear portion is welded to the side wall using a welding gun or is riveted to the side wall.

  According to 1st invention-5th invention, in the state which piled the pail container up and down, the strip | belt-shaped convex part along the horizontal direction which protrudes outside, such as a bead, and the upper end of a container are the full length of a convex part. Since the ear part and the convex part are stacked in contact with each other over a long distance, there is no risk of collapsing during transportation or damage of part of the container such as the ear part. Can be stacked up and down to increase loading efficiency.

  Moreover, according to the 1st invention-the 5th invention, since the relative attachment position with respect to the container main body of an ear part is not changed, there is no possibility that the intensity | strength of a container may fall or a usability may worsen. Moreover, according to the first to fifth inventions, apart from the edge usually roll-formed at the upper end of the container body, the convex portion is formed as downward as possible within a range where the loading efficiency of the empty container can be increased. Since it is molded, the container body has a high bending strength, and can effectively prevent deformation when the contents are filled and transported.

  In particular, according to the second aspect of the invention, in addition to the above-described effects, it is easy to form the detour portion, and the detour portion of the convex portion can be formed without increasing the processing cost of the convex portion. Further, the occurrence rate of defects in the convex portion processing is reduced and the yield is improved, and as a result, the unit price of the pail container can be reduced.

  Hereinafter, one embodiment for carrying out the taper pail container with a convex part concerning the present invention is described in detail, referring to drawings.

[First Embodiment]
First, the taper pail container with a convex part which concerns on 1st Embodiment of this invention is demonstrated using FIGS. As shown in FIGS. 1 and 2, a tapered pail container 1 with a convex portion according to a first embodiment of the present invention includes a steel container main body 2 and a handle 3 for carrying the container main body. It is a bucket-shaped canopy detachable lidless (open) steel pail that is used as a container for storing and transporting contents after the contents such as liquid and fluid are filled into the container body 2 later. .

<Container body>
As shown in FIGS. 1 to 4, the container main body 2 includes a substantially cylindrical side peripheral wall 20 that is a body portion of the container main body 2, and a bottom plate made of a disk-shaped steel plate that is crimped to the lower end of the side peripheral wall 20 21 or the like.

(Side wall)
The side peripheral wall 20 is roll-formed from a thin rectangular steel plate having a thickness of about 0.34 mm to 0.6 mm, and the rectangular end portions are joined to each other by seam welding or the like and formed into a cylindrical shape. 2 is a tapered cylindrical body (corresponding to the side peripheral surface of the inverted truncated cone) formed so as to gradually expand in diameter.

  The side peripheral wall 20 of the container body 2 according to the present embodiment has an inner diameter of the upper end opening of 285 mm, an inner diameter of the lower end opening of 272 mm, and a height of 361 mm. That is, the height of the container body 2 according to the present embodiment is also 361 mm.

  Thus, the illustrated pail container 1 is a tapered pail can that is tapered so that the diameter of the side peripheral wall 20 that becomes the body portion of the container body 2 increases upward, and a plurality of pail cans are stacked vertically. It is a stacker type that can be stacked many times.

  In addition, the edge of the upper end of the side peripheral wall 20 was rolled and formed by spin curl or the like so as not to expose the sharp end of the cut steel plate and to improve the bending strength of the upper end. It has a curled edge 22.

(bead)
In addition, the side peripheral wall 20 has an outer side of the container body 2 for the purpose of increasing strength in order to prevent deformation of the container such as a dent when the container body 2 is filled with the contents and conveyed. A belt-like bead 23 (Bead), which is a convex portion that curves and protrudes in a helicrug (waveform) shape, is formed along the horizontal direction.

  In addition, the bead 23 is formed with a bypass portion 24 so as to bypass the ear portion 4 described later upward, and the bypass portion 24 according to the present embodiment has a belt-like upper side portion along the horizontal direction. 24a and an oblique side 24b inclined with respect to the upper side 24a are provided. In other words, the bead 23 is a bead in which the detour portion 24 has a substantially trapezoidal Mt. Fuji shape, and the general portion 23a excluding the detour portion 24 is a bead having a horizontal straight line. Of course, as long as the detour portion detours the ear portion 4, a shape other than the substantially trapezoidal Mt. Fuji type is applicable.

  However, as with the pail container 1 according to the present embodiment, when the belt is formed of two belt-shaped beads of the upper side portion 24a and the general portion 23a, the detour portion 24 can be easily molded, and the convex portion is processed. The bypass portion 24 can be formed without increasing the cost. In addition, the occurrence rate of defects in bead convex processing is reduced, yield is improved, and as a result, the product unit price of the pail container 1 can be reduced.

  And as shown in FIG. 3, this bead 23 is formed so that the lower end may become a position lower than the lower end of the ear part 4 mentioned later. That is, the lower end of the ear part 4 is attached at a height of a distance H1 from the upper end of the side peripheral wall 20 (container body 2), and the lower end of the general part 23a that is the lower end of the bead 23 is the side peripheral wall 20 (container body 2). H1 <H2 when the distance H2 is formed at the height H2.

  In the pail container 1 according to the present embodiment, the distance H1 = 77 mm and the distance H2 = 81 mm. Moreover, the highest center height of the general part 23a is 73 mm from the upper end of the side peripheral wall 20, the highest center height of the upper side part 24a is 28 mm from the upper end of the side peripheral wall 20, and the bead 23 is 45 mm. It detours upwards.

(Bottom plate)
As shown in FIGS. 3 and 4, the bottom plate 21 is made of a thin disc-shaped steel plate similar to the side peripheral wall 20, and in order to ensure bending rigidity, a ring protruding upwardly in a corrugated (corrugated) shape is projected. Three ring-shaped beads 25, 26, and 27 are formed. Further, the edge portion 28 of the bottom plate 21 is bent downward and is crimped and joined to the edge of the lower end of the side peripheral wall 20.

<Handle>
As shown in FIGS. 1 and 2, the handle 3 includes a handle body 30 made of a steel wire (steel bar), and a cylindrical grip 31 made of a resin material fitted on the handle body 30. The container body 2 is fixed to the container body 2 by a later-described ear portion 4 which is a cup-shaped steel fitting.

<Ear part>
As shown in FIG. 5, the ear part 4 is attached to the ear part main body 40 formed in a cup shape from a thin steel plate similar to the side peripheral wall 20, and the left and right side parts of the ear part main body 40. A welding hole 41 used for welding with the side peripheral wall 20 and the like are formed, and a handle hole 42 is formed in the center of the ear part main body 40 to swing the handle main body 30 in a swingable manner. .

  The ear part 4 is attached to the side peripheral wall 20 by welding the welding rod 41 with a welding gun so as to be integrated with the side peripheral wall 20 for welding. At this time, the contact portion between the welding rod 41 and the side peripheral wall 20 is linear, and the welding rod 41 can be reliably welded to the side peripheral wall 20. The ear portion 4 may be riveted by providing a slightly wider ridge instead of the welding ridge 41 instead of being welded to the side peripheral wall 20 using a welding gun.

  As described above, according to the pail container 1 according to the present embodiment, the ear part 4 can be easily and reliably welded using the welding gun. Product unit price can be reduced. Moreover, according to the pail container 1, since the bead 23 is not formed in the vicinity of the ear part 4, welding with a welding gun is easy, and attachment of the ear part can be completed in a very short time. Similarly, when the ear part 4 is riveted, the bead 23 is not formed in the vicinity of the ear part 4, so that riveting is easy.

  In the pail container 1 according to the present embodiment, the ear portion 4 is attached at a position where the center of the handle hole 42 is 62.5 mm from the upper end of the side peripheral wall 20 as in the conventional pail container. Therefore, since the relative attachment position of the ear part 4 with respect to the container body 2 is not changed, there is no possibility that the strength of the container is lowered or the usability is deteriorated.

[Multi-stack state]
Next, using FIG. 6 to FIG. 10, a state in which the tapered pail containers 1 with convex portions according to the first embodiment described above are stacked in a plurality of layers in the vertical direction will be described in detail.

  As shown in FIGS. 6 and 7, when another pail container 1 is stacked on the above-described pail container 1, the side peripheral wall 20 which is the upper end of the container body 2 of the first-stage pail container 1. The bead 23 (general part 23a) of the second-stage pail container 1 comes into contact with the inner peripheral surface of the curl edge 22, and the second-stage pail container 1 is placed on the first-stage pail container 1. Will be placed.

  At this time, as described above, the lower end of the ear part 4, that is, the lower end of the ear part main body 40 is at a height of a distance H1 (H1 = 77 mm) from the upper end of the container main body 2 (upper end of the curl edge 22). The lower end of the bead 23, that is, the lower end of the general portion 23a is formed at a height of a distance H2 (H2 = 81 mm) from the upper end of the container body 2 (the upper end of the curl edge 22). And H1 <H2.

  For this reason, according to the taper pail container 1 with a convex part which concerns on 1st Embodiment, even when the pail container 1 is piled up and down, the lower pail container 1 does not contact | abut to the ear part 4 of the pail container 1 of an upper end. . Therefore, according to the pail container 1 which concerns on this embodiment, even if it is a case where it piles up many, there is no possibility that the ear part 4 may be damaged. At this time, if H1 <H2 is satisfied and H1 is as close as possible to H2, the strength of the container body 2 by the beads 23 is effectively strengthened and the stacking of the pail containers 1 is stacked. It is preferable because it is possible to achieve both efficiency improvement.

  Next, in a limited space such as a container ship, when a conventional pail container P1 as described in Patent Document 1 is stacked up and down, and when a pail container 1 according to the present embodiment is stacked up and down So, I examined the difference in the number of stacked stages.

  Specifically, the container size of 40 feet, which is a general container, is W = 2,349mm × H = 2,382mm × L = 12,004mm, so this pail and the actual pail container P1 in a space of 2,382mm height It was verified how many stages the pail container 1 according to the form was packed.

  As shown in FIG. 8, the height of the first stage is the same at 361 mm for both the conventional pail container P1 and the pail container 1 according to this embodiment. However, in the conventional pail container P1, the distance H3 from the container upper end to the lower end of the bead below the two-stage bead is 114 mm (see Table 1), and as described above, the lower end of the bead 23 of the pail container 1 Since the distance H2 from the upper end of the container body 2 is 81 mm, the distance H3 and the distance H2 are added after the second stage.

  When calculated, as shown in Table 1 below, in the conventional pail container P1, the inner height H = 2,382 mm of the container is exceeded at the 19th stage. On the other hand, in the pail container 1 according to the present embodiment, the inner height of the container is exceeded at the 26th stage. Therefore, as shown in FIG. 8, the conventional pail container P1 can be stacked in only 18 stages in the container, whereas the pail container 1 according to this embodiment can be stacked in 25 stages. In the calculation of Table 1, for the sake of safety, the calculation is performed with H2 = 81.5 mm. Moreover, the numerical value described is mm, the conventional product of Table 1 is the conventional pail container P1, and the embodiment is the pail container 1.

  That is, according to the pail container 1 according to the present embodiment, when the pail container P1, which is a conventional product, is stacked in 18 stages in a container having a height H = 2,382 mm, the pail container 1 can be stacked 7 stages more than the conventional product. That is, according to the pail container 1, the loading efficiency is improved by nearly 40% (7 / 18≈0.39) compared to the conventional case. For this reason, according to the pail container 1, the transport cost of the pail container 1 can be reduced correspondingly.

  FIG. 9 is a view showing a state where a plurality of conventional pail containers P2 described in Patent Document 2 are stacked, and FIG. 10 is a photograph showing a state where a plurality of conventional pail containers P2 are stacked. Since the pail container P2 has a structure that supports the load of the pail cans stacked in the ear part, as described in the background art, the pail container P2 is supported by two-point support in the ear part in the seesaw state. Therefore, as is clear from FIGS. 9 and 10, it tilts as it goes upward. For this reason, there is a possibility that the stacked pail cans may incline during transportation and collapse, and the pail cans before use may be damaged. In addition, since the stacked pail cans may come into contact with each other, there is a need to make an interval in the width direction, which reduces the loading efficiency.

  On the other hand, according to the pail container 1 according to the present embodiment, the pail container 1 is stacked up and down because the container body 2 is supported by the contact between the general part 23a that makes a substantially round turn and the curl edge 22. It can be placed stably even in the state where For this reason, according to the pail container 1, there is no possibility that the cargo collapses during transportation even when the pail container 1 is stacked, and there is no possibility that the pail container 1 is damaged in this respect. Further, there is no need to leave a gap in the width direction, and the loading efficiency is improved.

  In addition, according to the pail container 1 according to the present embodiment, the bead 23 (general) is positioned as low as possible within the range in which the loading efficiency of the empty container can be increased, separately from the curl edge 22 at the upper end of the container body 2. Since the portion 23a) is formed, the bending strength of the container body 2 is high, and deformation when the contents are filled and transported can be effectively prevented.

  Next, a tapered pail container 1 ′ with a convex portion according to a second embodiment of the present invention will be described with reference to FIGS. 11 to 15. The only difference from the tapered pail container 1 with the convex portion according to the first embodiment described above is only the shape of the bead formed on the container main body. Therefore, only that point will be mainly described, and the same components are denoted by the same reference numerals. The description is omitted.

  As shown in FIGS. 11 to 15, the side peripheral wall 20 ′ of the container body 2 of the tapered pail container 1 ′ with a convex portion according to the second embodiment is curved in a corrugated (waveform) shape to the outside of the container body 2 ′. A belt-like bead 23 ′, which is a protruding part protruding in the horizontal direction, is formed along the horizontal direction.

  However, unlike the bead 23 of the side peripheral wall 20 according to the first embodiment, the bead 23 ′ is not formed with a bypass portion so as to bypass the ear portion 4 upward. A general portion 23a ′ similar to the portion 23a extends in a straight band shape, is cut with a protruding height gradually decreasing in the vicinity of the ear portion 4, and no bead is formed around the ear portion 4. It is.

  Even if it is bead 23 'of the shape in which the bead is not formed in the circumference of ear part 4 in such a straight belt shape, it is formed so that the lower end may become a position lower than the lower end of ear part 4, That is, the lower end of the ear part 4 is attached at a height of a distance H1 from the upper end of the side peripheral wall 20 ′ (container body 2 ′), and the lower end of the general part 23a ′ that is the lower end of the bead 23 ′ is the side peripheral wall 20 ′. When formed at a height of a distance H2 from the upper end of the (container body 2 ′), the point that H1 <H2 is the same as the pail container 1 according to the first embodiment.

  For this reason, similarly to the pail container 1 according to the first embodiment, the tapered pail container 1 ′ with a convex portion according to the second embodiment can also exhibit the above-described effects, which is 40% (7 /18≈0.39) Loading efficiency can be improved. For this reason, according to the pail container 1 ', the transportation cost of the pail container 1 can be reduced correspondingly.

  Further, according to the pail container 1 ′, the pail container 1 ′ is supported by the contact between the general portion 23a ′ that makes a substantially round turn of the container body 2 ′ and the curl edge 22 in the same manner as the pail container 1. It can be placed stably even when stacked up and down. For this reason, according to the pail container 1 ′, there is no possibility that the cargo collapses during transportation even when the pail container 1 is stacked, and there is no possibility that the pail container 1 is damaged in this respect.

  Further, according to the pail container 1 ', the bead 23' (general part 23a ') is moved downward as much as possible within a range in which the loading efficiency of the empty container can be increased, separately from the curled edge 22 at the upper end of the container body 2'. Since the container body 2 'has a high bending strength, it is possible to effectively prevent deformation when the contents are filled and transported.

  As mentioned above, although the taper pail container with a convex part which concerns on embodiment of this invention was demonstrated in detail, all the embodiment mentioned above or illustrated showed only one embodiment actualized in implementing this invention. Therefore, the technical scope of the present invention should not be construed in a limited manner.

  In particular, a bucket-shaped pail can made of a tapered cylindrical body has been described as an example of a pail container according to an embodiment of the present invention. It can also be applied to other cans. Further, the present invention can be applied not only to a steel pail can but also to a resin container such as plastic. In the case of a resin pail container, a convex portion such as a reinforcing rib may be used instead of the bead exemplified as the convex portion. However, if it is a steel pail can like the taper pail container with a convex part which concerns on embodiment, while being able to accommodate various contents, a pail container (can) can be manufactured at low cost.
