特開２０１３−０４３６９０号公報JP 2013-043690 A

ここで、特許文献１記載の容器は、係合片ＰＩにおける張出部Ｏと、係合突起ＰＲとが係合することによって、第１の側壁ＷＡと第２の側壁ＷＢとを解除可能に連結している（図１３参照）。これにより、特許文献１記載の容器では、容器の落下に伴う衝撃によって側壁が捻られ、第１の側壁ＷＡと第２の側壁ＷＢが互いに引き離される方向に力Ｆが加わったとしても、係合片ＰＩが係合を解除する方向に弾性変形し難く、外力に対しても係合状態を維持することができる。 Here, the container described in Patent Literature 1 can be released from the first side wall WA and the second side wall WB by engaging the protruding portion O of the engagement piece PI with the engagement protrusion PR. They are connected (see FIG. 13). As a result, in the container described in Patent Document 1, the side wall is twisted due to the impact caused by the drop of the container, and even if the force F is applied in the direction in which the first side wall WA and the second side wall WB are separated from each other, The piece PI is not easily elastically deformed in the direction of releasing the engagement, and the engaged state can be maintained even with an external force.

この点、第１の側壁ＷＡと、第２の側壁ＷＢが互いに引き離される方向に、より大きな力Ｆを加えた場合、係合孔Ｈ内部の係合突起ＰＲは、係合片ＰＩにおける張出部Ｏを介して押し上げられる（図１３参照）。この時、力Ｆは、張出部Ｏを介して係合突起ＰＲの先端に作用し、トルクＴを発生させる為、当該係合突起ＰＲが形成されている板状部ＰＬの根元に、応力の集中する応力集中部Ｓが生じる。又、応力集中部Ｓの発生に伴い、係合片ＰＩの付け根に応力が集中することにもなる。この結果、係合突起ＰＲが形成されている板状部ＰＬにおける応力集中部Ｓや、係合片ＰＩの付け根等の劣化、破損を招き、第１の側壁ＷＡと、第２の側壁ＷＢとの連結に支障が出てしまう虞がある。 In this regard, when a larger force F is applied in the direction in which the first side wall WA and the second side wall WB are separated from each other, the engagement protrusion PR inside the engagement hole H is not projected from the engagement piece PI. It is pushed up through the part O (see FIG. 13). At this time, the force F acts on the tip of the engagement projection PR via the overhang portion O, and generates a torque T. Therefore, a stress is applied to the base of the plate-like portion PL where the engagement projection PR is formed. The stress concentration part S in which is concentrated occurs. Further, as the stress concentration portion S is generated, the stress is concentrated at the base of the engagement piece PI. As a result, the stress concentration portion S in the plate-like portion PL where the engagement protrusion PR is formed, the base of the engagement piece PI, and the like are deteriorated and damaged, and the first side wall WA and the second side wall WB There is a risk of hindering the connection.

The lower end protective frame 27 connects the lower ends of the pair of side portion protective frames 26 below the lower end of the engagement piece 21. The protective frame 25 has a pair of reinforcing portions that reinforce each of the pair of side portion protective frames 26 above the overhanging engagement portion 23.

続いて、底部側壁４２の上端面４４に形成された第２係合部５０の構成について、図面を参照しつつ詳細に説明する。第２係合部５０は、上述したように、底部側壁４２の上端面４４に形成されており、側壁部材１０の下端面１２に形成された第１係合部２０と係合することで、底部側壁４２に対して側壁部材１０を解除可能に連結する。 Next, the configuration of the second engagement portion 50 formed on the upper end surface 44 of the bottom side wall 42 will be described in detail with reference to the drawings. As described above, the second engaging portion 50 is formed on the upper end surface 44 of the bottom side wall 42, and by engaging with the first engaging portion 20 formed on the lower end surface 12 of the side wall member 10, The side wall member 10 is releasably connected to the bottom side wall 42.

第２係合部５０は、底部側壁４２の上端面４４に開口された係合孔５１を有している。当該係合孔５１は、底部側壁４２の下部側壁面４３と、下部側壁面４３に立設された一対の側面リブ５２と、第２係合部５０の下端部を構成する下端リブ５３と、下部側壁面４３と所定間隔を隔てて配設され、第２係合部５０の上側部分を構成する板状部５５と、によって構成され、下部側壁面４３に沿って延びている。上述したように、第２係合部５０の係合孔５１は、上述した第１係合部２０を構成する係合片２１及び保護枠２５により挿通される。 The second engagement portion 50 has an engagement hole 51 opened in the upper end surface 44 of the bottom side wall 42. The engaging hole 51 includes a lower side wall surface 43 of the bottom side wall 42, a pair of side ribs 52 erected on the lower side wall surface 43, a lower end rib 53 constituting a lower end portion of the second engaging portion 50, The lower side wall surface 43 is disposed at a predetermined interval, and is constituted by a plate-like portion 55 that constitutes the upper portion of the second engaging portion 50, and extends along the lower side wall surface 43. As described above, the engagement hole 51 of the second engagement portion 50 is inserted through the engagement piece 21 and the protective frame 25 that constitute the first engagement portion 20 described above.

第２係合部５０の下部には、開口部５８が形成されている。開口部５８は、板状部５５の下端から下端リブ５３の間であって、前記係合片２１によって前記係合孔５１を挿通した場合に、当該係合爪２２と対向する部分を開口して形成される。従って、第１係合部２０の係合片２１によって、第２係合部５０の係合孔５１を挿通した場合には、当該開口部５８を介して、係合片２１に形成された係合爪２２は、第２係合部５０の板状部５５下端と係合する（図９〜図１１参照）。 An opening 58 is formed in the lower portion of the second engagement portion 50. The opening 58 is located between the lower end and the lower end rib 53 of the plate-like portion 55, and opens a portion facing the engagement claw 22 when the engagement piece 21 is inserted through the engagement piece 21. Formed. Therefore, when the engagement piece 21 of the first engagement portion 20 is inserted through the engagement hole 51 of the second engagement portion 50, the engagement formed on the engagement piece 21 via the opening 58 is provided. The joint claw 22 engages with the lower end of the plate-like portion 55 of the second engagement portion 50 (see FIGS. 9 to 11).

図７、図８に示すように、板状部５５は、第２係合部５０において、下部側壁面４３に対向する面として形成されており、係合突起５６と、補強リブ５７とを有している。係合突起５６は、係合孔５１の内壁面を構成する板状部５５の一面側に形成されており、側面視で略三角形状に形成されている。 As shown in FIGS. 7 and 8, the plate-like portion 55 is formed as a surface facing the lower side wall surface 43 in the second engaging portion 50, and has engaging protrusions 56 and reinforcing ribs 57. doing. The engagement protrusion 56 is formed on one surface side of the plate-like portion 55 constituting the inner wall surface of the engagement hole 51, and is formed in a substantially triangular shape in a side view.

具体的には、係合突起５６は、第２係合部５０の下方に向かうに従って係合孔５１内部側に位置する第１傾斜面と、係合突起５６の下端から板状部５５の内壁面に向かうに従って上方に戻る第２傾斜面と、を有しており、張出係合部２３に対応する位置に形成されている（図１０参照）。従って、第１係合部２０の係合片２１によって、第２係合部５０の係合孔５１を挿通した場合には、係合片２１の張出係合部２３は、第２係合部５０の板状部５５に形成された係合突起５６の下面と、夫々係合する。 Specifically, the engagement protrusion 56 has a first inclined surface located on the inner side of the engagement hole 51 as it goes downward of the second engagement part 50, and an inner side of the plate-like part 55 from the lower end of the engagement protrusion 56. A second inclined surface returning upward as it goes to the wall surface, and is formed at a position corresponding to the overhanging engagement portion 23 (see FIG. 10). Accordingly, when the engagement piece 21 of the first engagement portion 20 is inserted through the engagement hole 51 of the second engagement portion 50, the overhanging engagement portion 23 of the engagement piece 21 is The lower surface of the engaging protrusion 56 formed on the plate-like portion 55 of the portion 50 is engaged with each other.

図７、図９に示すように、補強リブ５７は、板状部５５における係合突起５６が形成された面の裏面側（即ち、収納容器１の外表面側）に突出形成されており、板状部５５を縦横に延びている。当該補強リブ５７は、係合片２１の張出係合部２３と、係合突起５６との係合の際に加わる負荷に対して、係合突起５６が立設されている板状部５５の強度を確保する。 As shown in FIGS. 7 and 9, the reinforcing rib 57 is formed so as to protrude on the back surface side (that is, the outer surface side of the storage container 1) of the surface of the plate-like portion 55 where the engagement protrusion 56 is formed. The plate-like portion 55 extends vertically and horizontally. The reinforcing rib 57 is a plate-like portion 55 on which the engaging projection 56 is erected with respect to a load applied when the protruding engagement portion 23 of the engaging piece 21 is engaged with the engaging projection 56. Ensure the strength of.

続いて、側壁部材１０の下端面１２に形成された第１係合部２０と、底部側壁４２の上端面４４に形成された第２係合部５０との係合・解除動作について、図面を参照しつつ説明する。 Subsequently, the engagement / release operation of the first engagement portion 20 formed on the lower end surface 12 of the side wall member 10 and the second engagement portion 50 formed on the upper end surface 44 of the bottom side wall 42 will be described. This will be described with reference to FIG.

先ず、第１係合部２０と、第２係合部５０の係合動作について説明する。側壁部材１０の第１係合部２０が、底部側壁４２の第２係合部５０に挿入されると、係合片２１における張出係合部２３の下端部が係合突起５６の第１傾斜面に当接する。そして、張出係合部２３は、第１係合部２０の挿入に応じて、その下端部が係合突起５６の第１傾斜面に押圧される。上述したように、張出係合部２３は、係合片２１の下端部に形成されているので、係合片２１は、張出係合部２３が係合突起５６の第１傾斜面から受ける押圧力により、下部側壁面４３側に力を受け、収納容器１の外側が凸となるような弓なりに弾性変形する。 First, the engaging operation of the first engaging portion 20 and the second engaging portion 50 will be described. When the first engagement portion 20 of the side wall member 10 is inserted into the second engagement portion 50 of the bottom side wall 42, the lower end portion of the overhanging engagement portion 23 in the engagement piece 21 is the first of the engagement protrusion 56. Abuts against the inclined surface. Then, the lower end portion of the overhanging engagement portion 23 is pressed against the first inclined surface of the engagement protrusion 56 in accordance with the insertion of the first engagement portion 20. As described above, since the overhanging engagement portion 23 is formed at the lower end portion of the engagement piece 21, the overhanging engagement portion 23 is formed from the first inclined surface of the engagement protrusion 56. Due to the received pressing force, a force is received on the side of the lower side wall surface 43 and elastically deforms in a bow shape so that the outer side of the storage container 1 is convex.

この時、係合片２１が弓なりに弾性変形した場合に圧縮される側の面には、補助リブ２４が形成されている為、当該係合片２１を係合させる際に係る力に対抗し得る。これにより、係合片２１は、係合動作時における応力集中を緩和することができ、係合片２１の破損や白化を防止し得る。 At this time, since the auxiliary rib 24 is formed on the surface to be compressed when the engagement piece 21 is elastically deformed like a bow, the force against the engagement of the engagement piece 21 is counteracted. obtain. Thereby, the engagement piece 21 can relieve stress concentration during the engagement operation, and can prevent the engagement piece 21 from being damaged or whitened.

係合片２１の張出係合部２３が、係合孔５１内に形成された係合突起５６の第１傾斜面を越えると、図１０に示すように、係合片２１は弾性復帰し、張出係合部２３は、係合突起５６の第２傾斜面に当接して係合状態となる。又、係合片２１の弾性復帰と同時に、係合片２１に形成された係合爪２２は、第２係合部５０の開口部５８内に進入する。これにより、係合爪２２は、開口部５８の上端縁（即ち、板状部５５の下端）と係合する。 When the overhanging engagement portion 23 of the engagement piece 21 exceeds the first inclined surface of the engagement protrusion 56 formed in the engagement hole 51, the engagement piece 21 is elastically restored as shown in FIG. The overhanging engagement portion 23 comes into contact with the second inclined surface of the engagement protrusion 56 and enters an engaged state. Simultaneously with the elastic return of the engagement piece 21, the engagement claw 22 formed on the engagement piece 21 enters the opening 58 of the second engagement portion 50. Thereby, the engaging claw 22 engages with the upper end edge of the opening 58 (that is, the lower end of the plate-like portion 55).

ここで、係合突起５６の第２傾斜面は、板状部５５に向かうに従って上方に戻るように傾斜している。従って、張出係合部２３は、係合突起５６の第２傾斜面に当接している場合、側壁部材１０と底部側壁４２を互いに引き離すように動作させると、板状部５５に向かう方向（即ち、係合状態を維持する方向）に付勢される。 Here, the second inclined surface of the engagement protrusion 56 is inclined so as to return upward as it goes toward the plate-like portion 55. Accordingly, when the overhanging engagement portion 23 is in contact with the second inclined surface of the engagement protrusion 56, when the side wall member 10 and the bottom side wall 42 are operated to be separated from each other, the direction toward the plate-like portion 55 ( That is, it is biased in the direction in which the engaged state is maintained.

図１０、図１１に示すように、第１係合部２０と、第２係合部５０とが係合している場合、係合片２１の張出係合部２３と、係合孔５１内の係合突起５６とが係合すると共に、係合片２１の係合爪２２と、板状部５５の下端とが係合する。張出係合部２３と係合突起５６の係合と、係合爪２２と板状部５５下端との係合は、収納容器１の内外方向、及び、収納容器１の側壁に沿った方向に異なる位置となる。従って、側壁部材１０と底部側壁４２を互いに引き離すように動作させると、この時に、第１係合部２０の係合片２１と、第２係合部５０に作用する力を分散させることができる。 As shown in FIGS. 10 and 11, when the first engagement portion 20 and the second engagement portion 50 are engaged, the overhanging engagement portion 23 of the engagement piece 21 and the engagement hole 51. The engaging projection 56 is engaged with the engaging claw 22 of the engaging piece 21 and the lower end of the plate-like portion 55 is engaged. The engagement between the overhanging engagement portion 23 and the engagement protrusion 56 and the engagement between the engagement claw 22 and the lower end of the plate-like portion 55 are in the inner and outer directions of the storage container 1 and in the direction along the side wall of the storage container 1. Different positions. Accordingly, when the side wall member 10 and the bottom side wall 42 are operated so as to be separated from each other, the force acting on the engagement piece 21 of the first engagement portion 20 and the second engagement portion 50 can be dispersed at this time. .

そして、第１係合部２０と第２係合部５０が互いに係合されている場合、係合片２１と係合突起５６との周囲は、第１係合部２０の保護枠２５によって囲まれている。この時、保護枠２５は、第２係合部５０の係合孔５１の内側面（即ち、下部側壁面４３、側面リブ５２、下端リブ５３及び板状部５５）に当接或いは近接対向している。これにより、側壁部材１０と底部側壁４２との連結状態である場合に受ける外力の少なくとも一部は、第１係合部２０の保護枠２５と、第２係合部５０の係合孔５１における下部側壁面４３によって受け止めることができる。これにより、当該収納容器１によれば、張出係合部２３と係合突起５６に加わる負荷や、係合爪２２と板状部５５下端に加わる負荷を緩和することができ、外力に抗して係合状態を維持し得る。 When the first engagement portion 20 and the second engagement portion 50 are engaged with each other, the periphery of the engagement piece 21 and the engagement protrusion 56 is surrounded by the protective frame 25 of the first engagement portion 20. It is. At this time, the protective frame 25 is in contact with or in close proximity to the inner surface (that is, the lower side wall surface 43, the side rib 52, the lower end rib 53, and the plate-like portion 55) of the engagement hole 51 of the second engagement portion 50. ing. Thereby, at least a part of the external force received when the side wall member 10 and the bottom side wall 42 are connected is in the protective frame 25 of the first engaging portion 20 and the engaging hole 51 of the second engaging portion 50. It can be received by the lower side wall surface 43. Thereby, according to the said storage container 1, the load added to the overhanging engaging part 23 and the engagement protrusion 56 and the load added to the engaging claw 22 and the plate-shaped part 55 lower end can be relieved, and it resists external force. Thus, the engaged state can be maintained.

次に、第１係合部２０と、第２係合部５０の解除動作について説明する。第１係合部２０と、第２係合部５０との係合を解除する際には、先ず、係合片２１の張出係合部２３と、係合孔５１内部の係合突起５６との係合に加え、係合片２１の係合爪２２と、係合孔５１に係る板状部５５下端との係合を解除する必要がある。具体的には、係合片２１に形成された係合爪２２の近傍を、第２係合部５０の開口部５８を介して、底部側壁４２の下部側壁面４３側に向かって押圧することにより行なわれる（図９〜図１１参照）。係合爪２２の近傍を下部側壁面４３側に押圧することにより、係合片２１は、下部側壁面４３側に力を受け、収納容器１の外側が凸となるような弓なりに弾性変形する。これにより、張出係合部２３と係合突起５６との係合、及び、係合爪２２と板状部５５下端との係合を、同時に解除し得る。 Next, the releasing operation of the first engaging portion 20 and the second engaging portion 50 will be described. When releasing the engagement between the first engagement portion 20 and the second engagement portion 50, first, the overhanging engagement portion 23 of the engagement piece 21 and the engagement protrusion 56 inside the engagement hole 51 are used. In addition to the engagement, it is necessary to release the engagement between the engagement claw 22 of the engagement piece 21 and the lower end of the plate-like portion 55 related to the engagement hole 51. Specifically, the vicinity of the engaging claw 22 formed on the engaging piece 21 is pressed toward the lower side wall surface 43 side of the bottom side wall 42 through the opening 58 of the second engaging portion 50. (See FIGS. 9 to 11). By pressing the vicinity of the engaging claw 22 toward the lower side wall surface 43 side, the engaging piece 21 receives a force on the lower side wall surface 43 side and elastically deforms like a bow so that the outer side of the storage container 1 is convex. . Thereby, the engagement between the overhanging engagement portion 23 and the engagement protrusion 56 and the engagement between the engagement claw 22 and the lower end of the plate-like portion 55 can be simultaneously released.

そして、張出係合部２３と係合突起５６との係合、及び、係合爪２２と板状部５５下端との係合を解除した状態で、底部４０の下部側壁面４３から、側壁部材１０を引き離すように動かすことで、第１係合部２０と第２係合部５０との係合を解除し、下部側壁面４３から側壁部材１０を取り外すことができる。 Then, in a state in which the engagement between the overhanging engagement portion 23 and the engagement protrusion 56 and the engagement between the engagement claw 22 and the lower end of the plate-like portion 55 are released, the side wall extends from the lower side wall surface 43 of the bottom portion 40. By moving the member 10 so as to be separated, the engagement between the first engaging portion 20 and the second engaging portion 50 can be released, and the side wall member 10 can be detached from the lower side wall surface 43.

For example, as shown in FIG. 12, corner portions 11 A may be formed on both sides of the short side wall member 10 B so as to have a part of the long side wall of the storage container 1. According to this configuration, the long side wall member 10A is formed slightly shorter than the long side dimension of the storage container 1 because the corner portions 11A are formed on both sides of the short side wall member 10B. Therefore, according to the storage container 1, the long side wall member 10 A and the short side wall member 10 B can be stored inside the storage container 1 as long as they are along the same direction as the long side of the storage container 1 (see FIG. 12). ), The components of the storage container 1 can be stored and stored in a small space.

又、上述した実施形態においては、補強リブ５７は、図９等に示すように、板状部５５の一面において縦横に延びていたが、この態様に限定されるものではない。例えば、補強リブ５７が板状部５５において縦方向のみに延びていてもよいし、横方向のみに延びていてもよい。 In the embodiment described above, the reinforcing rib 57 extends vertically and horizontally on one surface of the plate-like portion 55 as shown in FIG. 9 and the like, but is not limited to this mode. For example, the reinforcing rib 57 may extend only in the vertical direction in the plate-like portion 55, or may extend only in the horizontal direction.

又、上述した実施形態においては、係合片２１を含む第１係合部２０を、側壁部材１０に形成し、係合孔５１を含む第２係合部５０を、底部側壁４２に形成していたが、この態様に限定されるものではない。例えば、第１係合部２０を、底部側壁４２に形成し、第２係合部５０を、側壁部材１０に形成する態様であってもよい。 In the above-described embodiment, the first engagement portion 20 including the engagement piece 21 is formed on the side wall member 10, and the second engagement portion 50 including the engagement hole 51 is formed on the bottom side wall 42.
