Description

本発明は、流動性を有する被収容物を収容する容器とともに包装ケースに収納され、前記容器が受ける衝撃や振動を吸収又は減衰するための合成樹脂製の緩衝部材に関する。   The present invention relates to a cushioning member made of a synthetic resin that is housed in a packaging case together with a container for housing an object having fluidity and absorbs or attenuates the shock and vibration received by the container.

電子写真方式の画像形成装置には、現像装置で消費されるトナー容器が着脱可能に設けられている（特許文献１参照）。前記トナー容器が画像形成装置の容器装着部に装着されると、前記トナー容器から前記現像装置にトナーが補給可能となる。前記トナー容器内のトナーが全て消費されると、トナーが充填された新たなトナー容器に交換される。   2. Description of the Related Art In an electrophotographic image forming apparatus, a toner container consumed by a developing device is detachably provided (see Patent Document 1). When the toner container is mounted on the container mounting portion of the image forming apparatus, toner can be supplied from the toner container to the developing device. When all the toner in the toner container is consumed, the toner container is replaced with a new toner container filled with toner.

交換対象である前記トナー容器は、段ボールケース等の包装ケースに収納された状態で市場に流通している。流通過程において、包装ケースに予期せぬ衝撃や振動が加えられると、トナー容器が傷ついたり破損する場合がある。そのため、従来、トナー容器を衝撃等から保護するために、トナー容器は衝撃や振動等を吸収又は減衰することのできる緩衝部材によって保護された状態で前記包装ケースに梱包される。前記緩衝部材の一例として、発泡スチロールや、段ボール製、内部に空気が封入されたエアーパック（特許文献２参照）などによって構成されたものが知られている。   The toner container to be replaced is distributed in the market in a state of being stored in a packaging case such as a cardboard case. During the distribution process, if an unexpected impact or vibration is applied to the packaging case, the toner container may be damaged or damaged. Therefore, conventionally, in order to protect the toner container from an impact or the like, the toner container is packaged in the packaging case in a state where the toner container is protected by a shock absorbing member capable of absorbing or attenuating the impact and vibration. As an example of the cushioning member, there is known one made of styrene foam, a cardboard box, and an air pack in which air is sealed (see Patent Document 2).

従来の緩衝部材は、包装ケースの内壁とトナー容器との隙間を埋めるように配置される。そのため、包装ケース内では、緩衝部材とトナー容器とが当接した状態を維持する。そのため、包装ケースに衝撃や振動が付与された場合に、その衝撃等が緩衝部材によって吸収又は減衰されるとしても、その全部が吸収されず、その衝撃等の一部が緩衝部材を通じてトナー容器にダイレクトに伝達する。とりわけ、トナー容器に設けられたトナー排出口を開閉するための開閉部材に緩衝部材が当接している場合、吸収しきれなかった衝撃等が開閉部材に伝達し、開閉部材とトナー排出口との間のシールを破り、シールの隙間からトナー容器内のトナーが外部に漏出するおそれがある。   The conventional cushioning member is arranged to fill a gap between the inner wall of the packaging case and the toner container. Therefore, the state where the buffer member and the toner container are in contact with each other is maintained in the packaging case. Therefore, when a shock or vibration is applied to the packaging case, even if the shock or the like is absorbed or attenuated by the cushioning member, not all of the shock or vibration is absorbed and a part of the shock or the like is transferred to the toner container through the cushioning member. Communicate directly. In particular, when the buffer member is in contact with the opening / closing member for opening / closing the toner discharge port provided in the toner container, the unabsorbed impact or the like is transmitted to the opening / closing member, and the gap between the opening / closing member and the toner discharge port is formed. The seal between the seals may be broken, and the toner in the toner container may leak to the outside through the gap between the seals.

That is, the image forming apparatus is configured such that only the toner container 40 having mounting compatibility can be mounted in the corresponding accommodating portion 22. In other words, each of the accommodating portions 22 is configured to be capable of selectively mounting a toner container 40 having mounting compatibility. For this reason, a connecting portion 80 is provided at the tip of the toner container 40 in the insertion direction D21. More specifically, the connecting portion 80 is formed integrally with an end face 59A of the base 59 on the side of the insertion direction D21. I have.

連結部８０は、絶縁体で構成された４つの互換キー８１を有する。４つの互換キー８１それぞれは、トナー容器４０に対応する前記被連結部に係合可能な位置に設けられている。互換キー８１は、端面５９Ａから前記挿入方向Ｄ２１側へ突出する突出部材であり、先端が扁平な形状に形成されている。４つの互換キー８１は、後述の突起８８（図１参照）を中心とする円の円周上に配置されている。これら４つの互換キー８１の配置位置は、トナー容器４０の種類ごとに異なる。   The connecting portion 80 has four compatible keys 81 made of an insulator. Each of the four compatible keys 81 is provided at a position which can be engaged with the connected portion corresponding to the toner container 40. The compatible key 81 is a protruding member that protrudes from the end face 59A toward the insertion direction D21, and has a flattened tip. The four compatible keys 81 are arranged on the circumference of a circle centered on a projection 88 (see FIG. 1) described later. The arrangement positions of these four compatible keys 81 are different for each type of toner container 40.

容器装着部２０の各収容部２２それぞれの奥側には、トナー容器４０に対応した被連結部（不図示）が設けられている。トナー容器４０が収容部２２に挿入されて、トナー容器４０の連結部８０が前記被連結部に係合した場合に、トナー容器４０の装着が許容される。一方、前被連結部にトナー容器４０の連結部８０が係合できない場合は、トナー容器４０の装着が禁止される。このように、前記被連結部と連結部８０とによる装着互換性を実現する構造は、一般に、非互換性構造と称されている。なお、非互換性構造についての詳細な説明は省略する。   A connected part (not shown) corresponding to the toner container 40 is provided on the back side of each of the storage parts 22 of the container mounting part 20. When the toner container 40 is inserted into the housing portion 22 and the connecting portion 80 of the toner container 40 is engaged with the connected portion, the mounting of the toner container 40 is allowed. On the other hand, when the connecting portion 80 of the toner container 40 cannot be engaged with the front connected portion, the mounting of the toner container 40 is prohibited. In this manner, a structure that achieves mounting compatibility between the connected portion and the connecting portion 80 is generally called an incompatible structure. A detailed description of the incompatible structure will be omitted.

図２に示すように、カバー部材４２は、トナー排出口４４（本発明の排出口の一例）を有する。トナー排出口４４は、容器本体４１に収容されたトナーを外側へ排出するためのものであり、カバー部材４２の外周壁に設けられている。図１及び２では、トナー排出口４４が下向きにされた状態が示されている。   As shown in FIG. 2, the cover member 42 has a toner outlet 44 (an example of the outlet of the present invention). The toner discharge port 44 is for discharging the toner stored in the container body 41 to the outside, and is provided on the outer peripheral wall of the cover member 42. FIGS. 1 and 2 show a state in which the toner discharge port 44 is directed downward.

トナー排出口４４は、カバー部材４２の外周壁を貫通する矩形状の貫通孔である。カバー部材４２の内部には、開口部５１とトナー排出口４４との間にトナー流通路４５が形成されている。トナー排出口４４を下側にした状態でトナー容器４０が容器装着部２０（図２参照）に装着されると、容器本体４１の開口部５１からトナー流通路４５に移動したトナーは、トナー流通路４５を通って下方へ案内されて、トナー排出口４４に達する。そして、トナー排出口４４が開放されている場合は、トナー排出口４４から下方外側へトナーが排出される。これにより、トナーが画像形成装置の現像装置（不図示）に補給される。一方、トナー排出口４４が閉塞されている場合、トナーは排出されず、トナー流通路４５がトナーで満たされた状態となる。   The toner outlet 44 is a rectangular through hole that penetrates the outer peripheral wall of the cover member 42. Inside the cover member 42, a toner passage 45 is formed between the opening 51 and the toner outlet 44. When the toner container 40 is mounted on the container mounting portion 20 (see FIG. 2) with the toner discharge port 44 facing downward, the toner that has moved from the opening 51 of the container main body 41 to the toner flow passage 45 will It is guided downward through the path 45 and reaches the toner discharge port 44. When the toner outlet 44 is open, the toner is discharged downward and outward from the toner outlet 44. Thereby, the toner is supplied to a developing device (not shown) of the image forming apparatus. On the other hand, when the toner outlet 44 is closed, the toner is not discharged, and the toner passage 45 is filled with the toner.

図２に示すように、カバー部材４２にスライド式の開閉部材４６が設けられている。開閉部材４６は、長手方向Ｄ２に長いプレート形状の部材であり、容器本体４１の長手方向Ｄ２へスライド可能にカバー部材４２に支持されている。開閉部材４６は、容器装着部２０に対するトナー容器４０の位置に応じて、トナー排出口４４を開閉する。開閉部材４６は、トナー容器４０が容器装着部２０に装着されると、トナー排出口４４を開放する。具体的には、トナー容器４０が容器装着部２０に装着されると、その装着動作にともない容器装着部２０から押圧力を受けて開閉部材４６がトナー排出口４４を開放する位置（開放位置）まで移動する。図２では、開閉部材４６が開放位置に配置されて、トナー排出口４４が開放された状態が示されている。トナー容器４０が容器装着部２０から取り外されると、その取り外し動作にともない開閉部材４６は前記開放位置から後方（挿入方向Ｄ２１）へ移動してトナー排出口４４を閉塞する位置（閉塞位置）まで移動して、トナー排出口４４を閉塞する。図２では、閉塞位置に配置された開閉部材４６が破線で示されている。   As shown in FIG. 2, a slide-type opening / closing member 46 is provided on the cover member 42. The opening / closing member 46 is a plate-shaped member that is long in the longitudinal direction D2, and is supported by the cover member 42 so as to be slidable in the longitudinal direction D2 of the container body 41. The opening / closing member 46 opens and closes the toner discharge port 44 according to the position of the toner container 40 with respect to the container mounting section 20. The opening / closing member 46 opens the toner discharge port 44 when the toner container 40 is mounted on the container mounting section 20. Specifically, when the toner container 40 is mounted on the container mounting portion 20, the opening / closing member 46 receives the pressing force from the container mounting portion 20 in accordance with the mounting operation, and the opening / closing member 46 opens the toner discharge port 44 (open position). Move up to. FIG. 2 shows a state where the opening / closing member 46 is arranged at the open position and the toner discharge port 44 is opened. When the toner container 40 is removed from the container mounting portion 20, the opening / closing member 46 moves rearward (in the insertion direction D21) from the open position and moves to a position (closed position) for closing the toner discharge port 44 with the removal operation. Then, the toner outlet 44 is closed. In FIG. 2, the opening / closing member 46 arranged at the closed position is indicated by a broken line.

容器装着部２０には、図示しないコイルバネ（付勢部材）が設けられており、前記開放位置から前記閉塞位置までの開閉部材４６の移動は、トナー容器４０の取り外し動作にともない前記コイルバネが開閉部材４６を相対的に後方へ移動させることにより行われる。また、トナー容器４０が容器装着部２０に装着されていない非装着状態である場合は、開閉部材４６は前記閉塞位置に維持される。   The container mounting portion 20 is provided with a coil spring (biasing member) (not shown). The movement of the opening / closing member 46 from the open position to the closing position is performed by the opening / closing member when the toner container 40 is removed. This is done by relatively moving 46 back. When the toner container 40 is not mounted on the container mounting portion 20 and is not mounted, the opening / closing member 46 is maintained at the closed position.

図２に示すように、開閉部材４６が前記閉塞位置にあるときに、開閉部材４６の挿入方向Ｄ２１の先端４６Ａは、突起８８の先端から挿入方向Ｄ２１側へ突出しており、トナー容器４０の挿入方向Ｄ２１側の先端から挿入方向Ｄ２１へ突出している。   As shown in FIG. 2, when the opening / closing member 46 is in the closed position, the tip 46 </ b> A of the opening / closing member 46 in the insertion direction D <b> 21 protrudes from the tip of the projection 88 in the insertion direction D <b> 21, and the insertion of the toner container 40 is performed. It protrudes from the tip on the direction D21 side in the insertion direction D21.

また、カバー部材４２は、端面５９Ａの中央に、挿入方向Ｄ２１側へ突出する突起８８（本発明の第１突出部の一例）を有する。突起８８は、開閉部材４６の近傍に設けられており、具体的には、図２において、開閉部材４６からカバー部材４２の高さサイズの半分程度の距離を上方へ隔てた位置に設けられている。突起８８は、収容部２２にトナー容器４０が装着されたときに、容器装着部２０に設けられた位置決め用の係合穴（不図示）に挿入されて係合される。これにより、収容部２２に定められた装着位置にトナー容器４０が位置決めされる。なお、収容部２２にトナー容器４０が装着されたときに前記コイルバネが圧縮されつつ孔６０に挿通される。そのため、前記コイルバネのバネ力によってトナー容器４０が外れないように、不図示のロック機構によって、収容部２２における前記装着位置でトナー容器４０はロックされる。   The cover member 42 has a protrusion 88 (an example of a first protrusion of the present invention) that protrudes toward the insertion direction D21 at the center of the end face 59A. The projection 88 is provided in the vicinity of the opening / closing member 46, and specifically, is provided at a position upwardly separated from the opening / closing member 46 by a distance of about half the height of the cover member 42 in FIG. 2. I have. The projection 88 is inserted and engaged in a positioning engagement hole (not shown) provided in the container mounting section 20 when the toner container 40 is mounted in the storage section 22. As a result, the toner container 40 is positioned at the mounting position defined in the storage section 22. When the toner container 40 is mounted in the housing 22, the coil spring is inserted into the hole 60 while being compressed. Therefore, the toner container 40 is locked at the mounting position in the storage section 22 by a lock mechanism (not shown) so that the toner container 40 does not come off due to the spring force of the coil spring.

カバー部材４２の外周壁において、開閉部材４６とは反対側には、概ね平坦な平坦面を有する平坦板４７が設けられている。平坦板４７は、トナー容器４０が後述する包装体１０の包装ケース１１に収納された場合に、包装ケース１１の底面に対向される部分である。トナー容器４０の長手方向Ｄ２が水平方向と一致するようにトナー容器４０が横置きにされた状態で、平坦板４７は、容器本体４１の外周面から容器本体４１の中心側へ所定距離ΔＤを隔てた位置に配置されている。   On the outer peripheral wall of the cover member 42, a flat plate 47 having a substantially flat flat surface is provided on a side opposite to the opening / closing member 46. The flat plate 47 is a portion facing the bottom surface of the packaging case 11 when the toner container 40 is stored in the packaging case 11 of the packaging body 10 described later. In a state where the toner container 40 is placed horizontally so that the longitudinal direction D2 of the toner container 40 coincides with the horizontal direction, the flat plate 47 moves a predetermined distance ΔD from the outer peripheral surface of the container main body 41 to the center side of the container main body 41. It is located at a distance.

次に、図４を参照して、本発明の実施形態に係る包装体１０について説明する。図４は、包装体１０を示す斜視図である。包装体１０は、上述のトナー容器４０と、衝撃又は振動などの外力を吸収又は減衰することができる後述の緩衝部材７０と、包装ケース１１とを備え、トナー容器４０及び緩衝部材７０が包装ケース１１に収納されたものである。上述した構成のトナー容器４０は、図４に示すように、緩衝部材７０とともに包装ケース１１に収納された状態の包装体１０として市場に流通される。   Next, the package 10 according to the embodiment of the present invention will be described with reference to FIG. FIG. 4 is a perspective view showing the package 10. The package 10 includes the toner container 40 described above, a cushioning member 70 that can absorb or attenuate an external force such as impact or vibration, and a packaging case 11, and the toner container 40 and the cushioning member 70 are 11. As shown in FIG. 4, the toner container 40 having the above-described configuration is distributed on the market as the package 10 housed in the packaging case 11 together with the cushioning member 70.

図４に示すように、包装体１０の包装ケース１１は、トナー容器４０及び緩衝部材７０を収容可能な容積を有しており、長尺な直方体形状に形成されている。包装ケース１１は、段ボールや厚紙などで構成されている。本実施形態では、トナー容器４０の先端部に緩衝部材７０が取り付けられた状態で、これら２つの部材が包装ケース１１の内部に収納されている。   As shown in FIG. 4, the packaging case 11 of the packaging body 10 has a volume capable of accommodating the toner container 40 and the cushioning member 70, and is formed in an elongated rectangular parallelepiped shape. The packaging case 11 is made of cardboard, cardboard, or the like. In the present embodiment, these two members are housed inside the packaging case 11 in a state where the cushioning member 70 is attached to the tip of the toner container 40.

次に、図５乃至図９を参照して、本実施形態に係る緩衝部材７０について説明する。   Next, the cushioning member 70 according to the present embodiment will be described with reference to FIGS.

緩衝部材７０は、可撓性を有しており、包装体１０の流通過程や運搬時に加えられた衝撃によって包装ケース１１に収納されたトナー容器４０が破損することを防止するためのものである。緩衝部材７０は、上述したように、トナー容器４０とともに包装ケース１１内に収納される。言い換えると、緩衝部材７０は、内部のトナー容器４０が受ける衝撃や振動等の外力を吸収又は減衰させて緩衝（緩和）させるためのものである。本実施形態では、緩衝部材７０は、合成樹脂によって金型を用いて一体成形されたものであり、合成樹脂製の成形品である。   The cushioning member 70 has flexibility, and is for preventing the toner container 40 housed in the packaging case 11 from being damaged by an impact applied during a distribution process or transportation of the packaging body 10. . The buffer member 70 is housed in the packaging case 11 together with the toner container 40 as described above. In other words, the cushioning member 70 absorbs or attenuates an external force such as an impact or vibration received by the internal toner container 40 to cushion (relax) the external force. In the present embodiment, the buffer member 70 is integrally formed of a synthetic resin using a mold, and is a molded product made of a synthetic resin.

ところで、従来の緩衝部材は、包装ケース１１の内壁とトナー容器４０との隙間を埋めるように配置されるものであり、そのため、包装ケース１１内では、従来の緩衝部材とトナー容器４０とが当接していた。とりわけ、トナー容器４０に設けられたトナー排出口４４を開閉するための開閉部材４６に従来の緩衝部材が当接している場合、吸収又は減衰しきれなかった外力が開閉部材４６に伝達し、開閉部材４６とトナー排出口４４との間のシールを破り、シールの隙間からトナー容器４０内のトナーが外部に漏出するおそれがある。これに対して、本実施形態の緩衝部材７０は、トナー容器４０の開閉部材４６に直接に衝撃や振動等の外力が加わらないように保護するとともに、外力を吸収又は減衰させる高い緩衝性能を実現することができる。   By the way, the conventional cushioning member is arranged so as to fill the gap between the inner wall of the packaging case 11 and the toner container 40. Therefore, in the packaging case 11, the conventional cushioning member and the toner container 40 are in contact. I was in contact. In particular, when a conventional cushioning member is in contact with an opening / closing member 46 for opening / closing the toner discharge port 44 provided in the toner container 40, an external force that cannot be absorbed or attenuated is transmitted to the opening / closing member 46, and There is a possibility that the seal between the member 46 and the toner discharge port 44 will be broken, and the toner in the toner container 40 will leak out from the gap of the seal. On the other hand, the cushioning member 70 of the present embodiment protects the opening and closing member 46 of the toner container 40 from directly applying external force such as impact or vibration, and realizes a high cushioning performance of absorbing or attenuating the external force. can do.

図５及び図６に示すように、緩衝部材７０は、大別して、収容部７１（本発明の収容部の一例）と、緩衝部７２とにより構成されている。なお、以下においては、包装ケース１１にトナー容器４０及び緩衝部材７０が収納される収納姿勢を基準にして、上下方向Ｄ３１、幅方向Ｄ３２、前後方向Ｄ３３を定義する。   As shown in FIGS. 5 and 6, the buffering member 70 is roughly divided into a housing 71 (an example of the housing of the present invention) and a buffer 72. In the following, the vertical direction D31, the width direction D32, and the front-back direction D33 are defined based on the storage posture in which the toner container 40 and the buffer member 70 are stored in the packaging case 11.

収容部７１は、概ね立方体形状に形成されており、平坦な底板７１１と、底板７１１の幅方向Ｄ３２の両端それぞれから上方へ垂直に延出する一対の側板７１２と、底板７１１の前方側の端部から上方へ垂直に延出する側板７１３（本発明の隔壁の一例）とを有する。収容部７１は、緩衝部材７０が包装ケース１１に収容された状態で、包装ケース１１の内壁面（底面及び内側面等）に接触可能なサイズ及び形状に形成されている。底板７１１は、包装ケース１１の底面に接触した状態で当該底面に載置される部分である。また、一対の側板７１２は、包装ケース１１において幅方向Ｄ３２に互いに対向する一対の内側面に接触する部分である。底板７１１及び一対の側板７１２が、包装ケース１１内において緩衝部材７０を安定させる。側板７１３は、一対の側板７１２それぞれの前端辺を幅方向Ｄ３２に渡すように設けられている。本実施形態では、側板７１３の高さサイズ（上下方向Ｄ３１の長さ）は、側板７１２の高さサイズよりも小さく、また、後述の緩衝部７２の高さサイズよりも小さい。   The accommodation portion 71 is formed in a substantially cubic shape, and has a flat bottom plate 711, a pair of side plates 712 extending vertically upward from both ends in the width direction D <b> 32 of the bottom plate 711, and a front end of the bottom plate 711. Side plate 713 (an example of the partition wall of the present invention) extending vertically upward from the portion. The accommodation portion 71 is formed in a size and a shape capable of contacting an inner wall surface (a bottom surface, an inner side surface, and the like) of the packaging case 11 in a state where the cushioning member 70 is accommodated in the packaging case 11. The bottom plate 711 is a portion placed on the bottom surface of the packaging case 11 in a state of being in contact with the bottom surface. In addition, the pair of side plates 712 are portions that come into contact with the pair of inner surfaces that face each other in the width direction D32 in the packaging case 11. The bottom plate 711 and the pair of side plates 712 stabilize the cushioning member 70 in the packaging case 11. The side plate 713 is provided so as to pass the front end side of each of the pair of side plates 712 in the width direction D32. In the present embodiment, the height size of the side plate 713 (the length in the up-down direction D31) is smaller than the height size of the side plate 712 and smaller than the height size of the buffer 72 described later.

底板７１１と各側板７１２と側板７１３とによって収容部７１の内部に収容空間７１４（図５参照）が区画形成されている。底板７１１は、包装ケース１１の底面に載置される部分であり、収容空間７１４の底側を区画する。包装ケース１１内にトナー容器４０と緩衝部材７０とが収納される際に、収容空間７１４に、トナー容器４０の先端部であるカバー部材４２が収容される。より詳細には、図８に示すように、トナー排出口４４及び開閉部材４６が上向きにされた状態で、開閉部材４６を含むカバー部材４２が収容部７１の収容空間７１４に収容される。収容空間７１４にカバー部材４２が収容された状態で、開閉部材４６は、底板７１１、一対の側板７１２、側板７１３によって囲まれる。本実施形態では、図８に示すように、収容部７１は、開閉部材４６に収容部７１が直接に接触しない状態（非接触状態）で収容空間７１４にカバー部材４２が収容される。   An accommodation space 714 (see FIG. 5) is formed in the accommodation part 71 by the bottom plate 711, the side plates 712, and the side plates 713. The bottom plate 711 is a portion placed on the bottom surface of the packaging case 11 and defines a bottom side of the accommodation space 714. When the toner container 40 and the buffer member 70 are stored in the packaging case 11, the cover member 42, which is the tip of the toner container 40, is stored in the storage space 714. More specifically, as shown in FIG. 8, the cover member 42 including the opening / closing member 46 is housed in the housing space 714 of the housing portion 71 with the toner discharge port 44 and the opening / closing member 46 facing upward. With the cover member 42 housed in the housing space 714, the opening / closing member 46 is surrounded by a bottom plate 711, a pair of side plates 712, and a side plate 713. In the present embodiment, as shown in FIG. 8, the cover member 42 is housed in the housing space 714 in a state where the housing 71 does not directly contact the opening / closing member 46 (non-contact state).

収容部７１において、後方側と上方側は開放されている。つまり、収容部７１は、後方側と上方側とを開放する開口部９１を有する。開口部９１は、一対の側板７１２及び側板７１３それぞれの上端と、一対の側板７１２及び底板７１１の後端とによって形成されている。   In the storage section 71, the rear side and the upper side are open. That is, the housing 71 has the opening 91 that opens the rear side and the upper side. The opening 91 is formed by the upper ends of the pair of side plates 712 and 713, and the rear ends of the pair of side plates 712 and the bottom plate 711.

収容空間７１４にカバー部材４２が収容された状態で、一対の側板７１２の上端は、カバー部材４２の上部に位置する開閉部材４６よりも上側の位置に達している。したがって、トナー容器４０及び緩衝部材７０が包装ケース１１に収納された収納姿勢（収納状態）において、包装ケース１１の底面、側面、及び上面の各内壁面はカバー部材４２に直接に接触せず、もちろん、開閉部材４６にも直接に接触しない。   In a state where the cover member 42 is housed in the housing space 714, the upper ends of the pair of side plates 712 have reached a position above the opening / closing member 46 located above the cover member 42. Therefore, in the storage posture (storage state) in which the toner container 40 and the buffer member 70 are stored in the packaging case 11, the inner wall surfaces of the bottom surface, the side surfaces, and the upper surface of the packaging case 11 do not directly contact the cover member 42, Of course, it does not directly contact the opening / closing member 46.

図５及び図７（Ａ）に示すように、一対の側板７１２それぞれの上端の後方側の端部には、幅方向Ｄ３２の外側へ突出する突起７１９が形成されている。本実施形態では、一方の突起７１９の突出端から他方の突起７１９の突出端までの間隔Ｌ１（図７（Ｃ）参照）は、包装ケース１１の内側面間の間隔Ｌ２（図４参照）よりも若干長い。つまり、収容部７１において、幅方向Ｄ３２における最大サイズである間隔Ｌ１は、間隔Ｌ２よりも大きい。したがって、トナー容器４０及び緩衝部材７０が包装ケース１１に収納された場合に、包装ケース１１の内側面に突起７１９が当接し、前記内側面に当接したことにより前記内側面から反力を受けることによって、一対の側板７１２が幅方向Ｄ３２の内側へ撓まされる。これにより、側板７１２が元に戻ろうとする復元力が弾性付勢力として突起７１９を介して前記内側面に付与される。これにより、包装ケース１１内において緩衝部材７０が安定する。また、包装ケース１１が、緩衝部材７０よりも柔らかい素材、例えば、上述した段ボールや厚紙などで構成されている場合は、前記弾性付勢力によって、突起７１９が前記内側面に食い込む。これによっても、包装ケース１１内において緩衝部材７０が安定する。   As shown in FIG. 5 and FIG. 7A, a projection 719 projecting outward in the width direction D32 is formed at the rear end of the upper end of each of the pair of side plates 712. In the present embodiment, the distance L1 (see FIG. 7C) from the protruding end of one protrusion 719 to the protruding end of the other protrusion 719 is greater than the distance L2 between the inner surfaces of the packaging case 11 (see FIG. 4). Is also slightly longer. That is, in the accommodation section 71, the interval L1, which is the maximum size in the width direction D32, is larger than the interval L2. Therefore, when the toner container 40 and the cushioning member 70 are stored in the packaging case 11, the projection 719 contacts the inner surface of the packaging case 11, and receives a reaction force from the inner surface by contacting the inner surface. Thereby, the pair of side plates 712 are bent inward in the width direction D32. As a result, a restoring force for the side plate 712 to return to its original state is applied to the inner surface via the protrusion 719 as an elastic urging force. Thereby, the cushioning member 70 is stabilized in the packaging case 11. When the packaging case 11 is made of a material softer than the cushioning member 70, for example, the above-described cardboard or cardboard, the elastic biasing force causes the protrusion 719 to bite into the inner surface. This also stabilizes the cushioning member 70 in the packaging case 11.

図５及び図７（Ｂ）に示すように、緩衝部材７０の一対の側板７１２それぞれは、それらの後端辺から幅方向Ｄ３２の内側へ向けて突出する突出板７１２Ａを有する。突出板７１２Ａは、側板７１２と概ね同じ厚みの板状に形成されており、前記後端辺において側板７１２と概ね直角に屈曲している。   As shown in FIGS. 5 and 7B, each of the pair of side plates 712 of the cushioning member 70 has a protruding plate 712A that protrudes inward in the width direction D32 from the rear end side thereof. The protruding plate 712A is formed in a plate shape having substantially the same thickness as the side plate 712, and is bent at a substantially right angle with the side plate 712 at the rear end side.

各突出板７１２Ａの突出方向の端部（幅方向Ｄ３２の内側の端部）には、支持部７１７が突出板７１２Ａに一体に形成されている。各支持部７１７は、各突出板７１２Ａの前記端部から幅方向Ｄ３２の内側へ突出している。各支持部７１７は、突出板７１２Ａの端辺において上下方向Ｄ３１の概ね中央に設けられている。支持部７１７は、トナー容器４０のカバー部材４２が収容空間７１４に収容された状態で、駆動伝達部４３の筒状部４３Ｂを支持する。各支持部７１７は、側板７１２側（幅方向Ｄ３２の外側）へ凹状に湾曲した形状に形成されている。   A support portion 717 is formed integrally with the protruding plate 712A at an end of the protruding plate 712A in the protruding direction (an inner end in the width direction D32). Each support portion 717 protrudes inward in the width direction D32 from the end of each protruding plate 712A. Each support portion 717 is provided substantially at the center in the up-down direction D31 on the edge of the protruding plate 712A. The support portion 717 supports the cylindrical portion 43B of the drive transmission unit 43 in a state where the cover member 42 of the toner container 40 is stored in the storage space 714. Each support portion 717 is formed in a shape curved concavely toward the side plate 712 (outside in the width direction D32).

各支持部７１７それぞれには、互いに対をなす２つの湾曲部７１７Ａ，７１７Ｂが形成されている。２つの湾曲部７１７Ａ，７１７Ｂは、支持部７１７の上下方向Ｄ３１の概ね中央を基準にして上下に隔てて設けられている。一対の湾曲部７１７Ａ，７１７Ｂのうち、上側に湾曲部７１７Ａが配置され、下側に湾曲部７１７Ｂが配置されている。各湾曲部７１７Ａ，７１７Ｂの端面には、筒状部４３Ｂ（図２参照）の外周面と概ね同じ曲率の湾曲面７１７１（図１０参照）が形成されている。カバー部材４２が収容空間７１４に収容された状態で、支持部７１７の湾曲部７１７Ａ，７１７Ｂが駆動伝達部４３の筒状部４３Ｂ（図２参照）の外周面に当接して筒状部４３Ｂを支持することにより、容器本体４１の前記挿入方向Ｄ２１側の端部が各支持部７１７によって支持される。なお、突出板７１２Ａは、収容部７１において後方側の端部に設けられている。そのため、湾曲部７１７Ａ，７１７Ｂが駆動伝達部４３の筒状部４３Ｂに当接しても、その接触部からカバー部材４２を伝って開閉部材４６まで振動や衝撃などの外力が伝達しにくい。   Each of the support portions 717 has two curved portions 717A and 717B that form a pair. The two curved portions 717A, 717B are vertically separated from each other with reference to the approximate center of the support portion 717 in the vertical direction D31. Of the pair of curved portions 717A and 717B, the curved portion 717A is disposed on the upper side, and the curved portion 717B is disposed on the lower side. A curved surface 7171 (see FIG. 10) having substantially the same curvature as the outer peripheral surface of the cylindrical portion 43B (see FIG. 2) is formed on an end surface of each of the curved portions 717A and 717B. With the cover member 42 accommodated in the accommodation space 714, the curved portions 717A and 717B of the support portion 717 come into contact with the outer peripheral surface of the cylindrical portion 43B (see FIG. 2) of the drive transmission portion 43, and the cylindrical portion 43B is moved. By supporting, the end of the container main body 41 on the side of the insertion direction D21 is supported by each support portion 717. The protruding plate 712 </ b> A is provided at an end on the rear side in the housing section 71. Therefore, even when the curved portions 717A and 717B abut on the cylindrical portion 43B of the drive transmission portion 43, it is difficult for external forces such as vibration and impact to be transmitted from the contact portion through the cover member 42 to the opening / closing member 46.

図１０は、図７（Ｂ）における切断線Ｘ−Ｘの断面を示す模式断面図である。図１０に示すように、湾曲部７１７Ｂの後方側の端面には、傾斜ガイド面７１７２が形成されている。傾斜ガイド面７１７２は、各湾曲部７１７Ｂの間隔を前方へ向けて小さくするように傾斜する傾斜面である。トナー容器４０のカバー部材４２が収容空間７１４に挿入される際に、駆動伝達部４３が傾斜ガイド面７１７２に当接すると、駆動伝達部４３が傾斜ガイド面７１７２によって収容空間７１４側へ案内される。また、湾曲部７１７Ｂには、返し部７１７３が設けられている。返し部７１７３は、湾曲面７１７１の前端部から幅方向Ｄ３２の外側へ退避した段差部である。この返し部７１７３が設けられているため、収容空間７１４にカバー部材４２が収容された状態で、トナー容器４０が後方へ引っ張られた場合に、返し部７１７３がカバー部材４２に引っ掛かり、トナー容器４０と緩衝部材７０とが一緒に引っ張り方向へ移動する。なお、返し部７１７３は、上側の湾曲部７１７Ａに設けられていてもよい。   FIG. 10 is a schematic cross-sectional view showing a cross section taken along the line XX in FIG. 7B. As shown in FIG. 10, an inclined guide surface 7172 is formed on the rear end surface of the curved portion 717B. The inclined guide surface 7172 is an inclined surface that is inclined so as to decrease the interval between the curved portions 717B toward the front. When the drive transmitting unit 43 comes into contact with the inclined guide surface 7172 when the cover member 42 of the toner container 40 is inserted into the accommodation space 714, the drive transmission unit 43 is guided toward the accommodation space 714 by the inclined guide surface 7172. . The bending portion 717B is provided with a return portion 7173. The return portion 7173 is a stepped portion that is retracted outward from the front end of the curved surface 7171 in the width direction D32. Since the return portion 7173 is provided, when the toner container 40 is pulled backward in a state where the cover member 42 is stored in the storage space 714, the return portion 7173 is caught by the cover member 42 and the toner container 40 And the buffer member 70 move together in the pulling direction. Note that the return portion 7173 may be provided on the upper curved portion 717A.

図５に示すように、一対の側板７１２それぞれは、その下端部に止め板７１８を有する。止め板７１８は、底板７１１の幅方向Ｄ３２の両端辺との間に形成されている。止め板７１８は、底板７１１の幅方向Ｄ３２の両端辺それぞれから上方へ垂直に立設している。止め板７１８は、前後方向Ｄ３３に延びる板状に形成されている。側板７１２の中央部には、矩形状の開口９２が形成されており、止め板７１８は、開口９２の下端部を区画している。   As shown in FIG. 5, each of the pair of side plates 712 has a stopper plate 718 at the lower end thereof. The stop plate 718 is formed between both ends of the bottom plate 711 in the width direction D32. The stopper plate 718 is vertically set up vertically from each of both ends in the width direction D32 of the bottom plate 711. The stop plate 718 is formed in a plate shape extending in the front-rear direction D33. A rectangular opening 92 is formed in the center of the side plate 712, and the stopper plate 718 partitions the lower end of the opening 92.

止め板７１８は、一対の側板７１２よりも幅方向Ｄ３２の内側へ所定間隔を隔てた位置に配置されている。そのため、開口９２は、図７（Ａ）に示すように、緩衝部材７０の平面視において、幅方向Ｄ３２の内側へ前記所定間隔の分だけ拡張している。底板７１１及び一対の止め板７１８の幅方向Ｄ３２のサイズは、カバー部材４２の平坦板４７（図１及び図２参照）の幅に対応して定められており、例えば、平坦板４７の幅と概ね同じ、或いは若干長い。このため、平坦板４７が下向きにされたカバー部材４２が収容部７１の収容空間７１４に収容された状態で、カバー部材４２が周方向に回ろうとすると、平坦板４７の幅方向Ｄ３２の両端辺が止め板７１８に接触し、それ以上の回動を制止する。つまり、一対の止め板７１８は、カバー部材４２の周方向の回転を規制する。したがって、一対の止め板７１８は、カバー部材４２の周方向の回転を規制する回り止めの役割を果たす。   The stop plate 718 is disposed at a position spaced a predetermined distance inward in the width direction D32 from the pair of side plates 712. Therefore, as shown in FIG. 7A, the opening 92 extends inward in the width direction D <b> 32 by the predetermined distance in a plan view of the cushioning member 70. The size of the bottom plate 711 and the pair of stopper plates 718 in the width direction D32 is determined according to the width of the flat plate 47 (see FIGS. 1 and 2) of the cover member 42. Generally the same or slightly longer. For this reason, when the cover member 42 tries to rotate in the circumferential direction in a state where the cover member 42 with the flat plate 47 facing downward is accommodated in the accommodation space 714 of the accommodation portion 71, both ends of the flat plate 47 in the width direction D32. Contacts the stop plate 718 and stops further rotation. That is, the pair of stopper plates 718 regulate the rotation of the cover member 42 in the circumferential direction. Therefore, the pair of stopper plates 718 serves as a detent for restricting the circumferential rotation of the cover member 42.

図５に示すように、底板７１１の幅方向Ｄ３２の両端辺と止め板７１８との隅部に複数の傾斜リブ７１５が形成されている。各傾斜リブ７１５は、前後方向Ｄ３３に均等間隔に配置されている。傾斜リブ７１５は、止め板７１８の内面から底板７１１の上面へ向けて斜め下方へ傾斜する三角形状に形成されている（図７（Ｂ）参照）。収容空間７１４にカバー部材４２が収容された場合に、カバー部材４２の平坦板４７の両端辺が傾斜リブ７１５に当接することにより、平坦板４７が底板７１１の上面へ案内される。本実施形態では、傾斜リブ７１５は、収容部７１の強度を補強する補強リブの役割と、止め板７１８や側板７１２が幅方向Ｄ３２の外側へ広がることを抑制する役割を担っている。   As shown in FIG. 5, a plurality of inclined ribs 715 are formed at the corners of both ends of the bottom plate 711 in the width direction D32 and the stopper plate 718. Each inclined rib 715 is arranged at equal intervals in the front-back direction D33. The inclined rib 715 is formed in a triangular shape inclined obliquely downward from the inner surface of the stopper plate 718 toward the upper surface of the bottom plate 711 (see FIG. 7B). When the cover member 42 is accommodated in the accommodation space 714, the flat plate 47 of the cover member 42 is guided to the upper surface of the bottom plate 711 by contacting both ends of the flat plate 47 with the inclined ribs 715. In the present embodiment, the inclined rib 715 has a role of a reinforcing rib that reinforces the strength of the housing portion 71 and a role of preventing the stop plate 718 and the side plate 712 from spreading outward in the width direction D32.

図５に示すように、緩衝部材７０は、２つの補強部７４（本発明の補強部の一例）を有する。各補強部７４は、収容部７１の剛性を高めて収容部７１の上下方向Ｄ３１の強度を補強するものである。各補強部７４は、収容部７１の後端部において幅方向Ｄ３２の両端部に設けられている。補強部７４は、底板７１１に対して垂直に上方向へ延出している。図１１は、図７（Ｂ）における切断線ＸＩ−ＸＩの断面を示す模式断面図である。図１１に示すように、補強部７４は、周方向に屈曲した板状部で構成されており、具体的には、側板７１２、及び突出板７１２Ａの各板状部により構成されている。とりわけ、補強部７４の下端部７４１は、側板７１２、突出板７１２Ａ、及び止め板７１８から幅方向Ｄ３２の外側へ突出する補強板７１８Ａの各板状部により構成されている。   As shown in FIG. 5, the cushioning member 70 has two reinforcing portions 74 (an example of the reinforcing portion of the present invention). Each reinforcing portion 74 enhances the rigidity of the housing portion 71 to reinforce the strength of the housing portion 71 in the vertical direction D31. Each reinforcing portion 74 is provided at both ends in the width direction D32 at the rear end of the accommodation portion 71. The reinforcing portion 74 extends vertically upward with respect to the bottom plate 711. FIG. 11 is a schematic cross-sectional view showing a cross section taken along a cutting line XI-XI in FIG. As shown in FIG. 11, the reinforcing portion 74 is configured by a plate-shaped portion bent in the circumferential direction, and specifically, is configured by each plate-shaped portion of the side plate 712 and the protruding plate 712A. In particular, the lower end portion 741 of the reinforcing portion 74 is configured by a plate-shaped portion of a side plate 712, a protruding plate 712A, and a reinforcing plate 718A protruding outward from the stopper plate 718 in the width direction D32.

図１１に示すように、下端部７４１は、平面視で概ね四角筒状に形成されている。より詳細には、下端部７４１において、側板７１２よりも幅方向Ｄ３２の内側には、上下方向Ｄ３１に延びるスリット７４２（本発明の不連続部の一例）が形成されている。下端部７４１には、補強板７１８Ａから後方へ突出する板状のリブ７４３と、突出板７１２Ａから前方へ延びる板状のリブ７４４とが設けられており、これらの各リブ７４３，７４４は下端部７４１だけに設けられている。スリット７４２は、各リブ７４３，７４４により挟まれた空隙である。このスリット７４２が形成されているため、下端部７４１の外周面は、周方向において連続しない。   As shown in FIG. 11, the lower end portion 741 is formed in a substantially rectangular tube shape in plan view. More specifically, a slit 742 (an example of a discontinuous portion of the present invention) extending in the up-down direction D31 is formed in the lower end portion 741 inside the side plate 712 in the width direction D32. The lower end portion 741 is provided with a plate-like rib 743 protruding rearward from the reinforcing plate 718A and a plate-like rib 744 extending forward from the protruding plate 712A. 741 only. The slit 742 is a gap between the ribs 743 and 744. Since the slit 742 is formed, the outer peripheral surface of the lower end portion 741 is not continuous in the circumferential direction.

このような補強部７４が緩衝部材７０に設けられているため、補強部７４全体が収容部７１の強度を補強することにより収容部７１が高められる。また、補強部７４の下端部７４１においては、各リブ７４３、７４４によって更に強度が補強されつつも、スリット７４２によって前後方向Ｄ３３及び幅方向Ｄ３２の可撓性が実現される。このため、仮に、包装体１０が予期せぬ外力を受けて、その外力が収容部７１の補強部７４に付与されたとしても、補強部７４の損傷を防止することができ、特に、下端部７４１の破壊が防止される。   Since such a reinforcing portion 74 is provided in the cushioning member 70, the housing portion 71 is enhanced by the entire reinforcing portion 74 reinforcing the strength of the housing portion 71. Further, at the lower end portion 741 of the reinforcing portion 74, the flexibility in the front-rear direction D33 and the width direction D32 is realized by the slit 742 while the strength is further reinforced by the ribs 743 and 744. Therefore, even if the package 10 receives an unexpected external force and the external force is applied to the reinforcing portion 74 of the housing portion 71, the reinforcing portion 74 can be prevented from being damaged. 741 is prevented from being broken.

側板７１３の後方側、つまり、側板７１３において収容空間７１４側の側面７１３Ａ（壁面）には、当接部７１６が設けられている。当接部７１６は、側面７１３Ａの中央付近から後方へ垂直に突出している。つまり、当接部７１６は、側面７１３Ａに突設されている。包装ケース１１の内部において、カバー部材４２が収容空間７１４に収容された状態で、当接部７１６は、カバー部材４２の突起８８に当接する（図９参照）。これにより、トナー容器４０と緩衝部材７０とが包装ケース１１に収納された収納姿勢において、側板７１３は、開閉部材４６との間で非接触状態を維持することができる。   A contact portion 716 is provided on the rear side of the side plate 713, that is, on the side surface 713A (wall surface) of the side plate 713 on the side of the accommodation space 714. The contact portion 716 vertically protrudes rearward from near the center of the side surface 713A. That is, the contact portion 716 is provided to protrude from the side surface 713A. In the state where the cover member 42 is accommodated in the accommodation space 714 inside the packaging case 11, the contact portion 716 contacts the projection 88 of the cover member 42 (see FIG. 9). Accordingly, in the storage posture in which the toner container 40 and the buffer member 70 are stored in the packaging case 11, the side plate 713 can maintain a non-contact state with the opening / closing member 46.

緩衝部７２は、収容部７１の前方側に配置されており、収容部７１の側板７１３に連接している。詳細には、緩衝部７２は、一対の連接板７２１を介して側板７１３に連接している。緩衝部７２は、前記収納姿勢において開閉部材４６に対して直接に接触しておらず、非接触状態で収容部７１に連接している。   The buffer section 72 is arranged on the front side of the storage section 71 and is connected to the side plate 713 of the storage section 71. Specifically, the buffer section 72 is connected to the side plate 713 via a pair of connecting plates 721. The buffer section 72 is not in direct contact with the opening / closing member 46 in the storage posture, but is connected to the storage section 71 in a non-contact state.

緩衝部７２は、開閉部材４６のスライド方向（開閉方向）の外力が加えられた場合にその外力を吸収又は減衰することができるように、同方向に弾性を有する。具体的には、緩衝部７２は、開閉部材４６のスライド方向に直交する上下方向Ｄ３１を中心軸とする円筒形状に形成された筒部７２２を有する。筒部７２２の上下方向Ｄ３１の両側は開放されている（図７（Ｃ）参照）。   The cushioning section 72 has elasticity in the same direction so that when an external force in the sliding direction (opening / closing direction) of the opening / closing member 46 is applied, the external force can be absorbed or attenuated. Specifically, the buffer section 72 has a cylindrical section 722 formed in a cylindrical shape with a vertical axis D31 perpendicular to the sliding direction of the opening / closing member 46 as a central axis. Both sides of the cylindrical portion 722 in the vertical direction D31 are open (see FIG. 7C).

一対の連接板７２１それぞれは、緩衝部７２の筒部７２２と側板７１３とを連接するものであり、所定の方向へ撓むことが可能な可撓性を有する。一対の連接板７２１それぞれは、本発明の連接部の一例である。図５及び図９に示すように、一対の連接板７２１は、上下方向Ｄ３１へ延出しており、上下方向Ｄ３１に長い板状に形成されている。このため、仮に、トナー容器４０と緩衝部材７０とが包装ケース１１に収納された収納状態で、幅方向Ｄ３２の外力が緩衝部７２に加えられると、連結板７２１は、幅方向Ｄ３２へ撓むことにより、収容部７１に前記外力が伝達しないように前記外力を吸収又は減衰させることができる。なお、上下方向Ｄ３１は、前記収納姿勢における開閉部材４６の前記スライド方向に直交する方向の一例である。   Each of the pair of connecting plates 721 connects the cylindrical portion 722 of the buffer portion 72 and the side plate 713, and has flexibility to bend in a predetermined direction. Each of the pair of connecting plates 721 is an example of the connecting portion of the present invention. As shown in FIGS. 5 and 9, the pair of connecting plates 721 extend in the up-down direction D31 and are formed in a long plate shape in the up-down direction D31. For this reason, if an external force in the width direction D32 is applied to the buffer portion 72 in a state where the toner container 40 and the buffer member 70 are stored in the packaging case 11, the connecting plate 721 bends in the width direction D32. Thereby, the external force can be absorbed or attenuated so that the external force is not transmitted to the housing portion 71. The vertical direction D31 is an example of a direction orthogonal to the sliding direction of the opening / closing member 46 in the storage posture.

各連接板７２１は、側板７１３の前方側、つまり、側板７１３において緩衝部７２側の側面７１３Ｂ（壁面）の中央に設けられている。詳細には、各連接板７２１は、側面７１３Ｂにおいて、幅方向Ｄ３２の中央に設けられている。各連接板７２１は、幅方向Ｄ３２に所定間隔を隔てて互いに対向しており、互いに平行を保った状態で上下方向Ｄ３１へ延出している。前記所定間隔は、側板７１３の幅方向Ｄ３２のサイズよりも十分に小さいサイズである。このような位置に設けられているため、各連結板７２１は、幅方向Ｄ３２へより撓み易くなる。したがって、仮に、幅方向Ｄ３２の外力が緩衝部７２に加えられると、連結板７２１は幅方向Ｄ３２へ容易に撓み、前記外力をより吸収又は減衰することができる。   Each connecting plate 721 is provided on the front side of the side plate 713, that is, at the center of the side surface 713B (wall surface) of the side plate 713 on the buffer unit 72 side. Specifically, each connecting plate 721 is provided at the center in the width direction D32 on the side surface 713B. The connecting plates 721 are opposed to each other at a predetermined interval in the width direction D32, and extend in the up-down direction D31 while being kept parallel to each other. The predetermined interval is a size sufficiently smaller than the size of the side plate 713 in the width direction D32. Since the connecting plates 721 are provided at such positions, the connecting plates 721 are more easily bent in the width direction D32. Therefore, if an external force in the width direction D32 is applied to the buffer portion 72, the connecting plate 721 bends easily in the width direction D32, and can absorb or attenuate the external force.

一対の連接板７２１は、側板７１３の下端から上端まで延在している。上述したように、側板７１３の高さサイズＨ１（上下方向Ｄ３１の長さ、図７（Ｂ）参照）は、緩衝部７２の高さサイズＨ２（図７（Ａ）参照）よりも小さい。本実施形態では、側板７１３の高さサイズＨ１は、緩衝部７２の高さサイズＨ２の概ね半分程度である。したがって、連接板７２１の高さサイズも、緩衝部７２の高さサイズＨ２よりも小さい。このため、仮に、トナー容器４０と緩衝部材７０とが包装ケース１１に収納された収納状態で、前後方向Ｄ３３の外力が緩衝部７２に加えられた場合に、緩衝部７２の筒部７２２が上下方向Ｄ３１のいずれかの方向へ撓まされても、連接板７２１は、側板７１３とともに同方向へ撓まされる。これにより、上下方向Ｄ３１の外力が緩衝部７２に加えられても、各連接板７２１によってその外力が吸収又は減衰される。また、側板７１３と連接板７２１との境目に過剰な応力が生じ無くなり、当該境目に上下方向Ｄ３１の亀裂が生じることが防止され、連接板７２１の損傷が防止される。   The pair of connecting plates 721 extend from the lower end to the upper end of the side plate 713. As described above, the height H1 of the side plate 713 (the length in the vertical direction D31, see FIG. 7B) is smaller than the height H2 of the buffer 72 (see FIG. 7A). In the present embodiment, the height H1 of the side plate 713 is approximately half the height H2 of the buffer 72. Therefore, the height of the connecting plate 721 is also smaller than the height H2 of the buffer 72. For this reason, if an external force in the front-rear direction D33 is applied to the buffer unit 72 in a storage state where the toner container 40 and the buffer member 70 are stored in the packaging case 11, the cylindrical portion 722 of the buffer unit 72 moves up and down. Even if the connecting plate 721 is bent in any direction of the direction D31, the connecting plate 721 is bent in the same direction together with the side plate 713. Thus, even if an external force in the vertical direction D31 is applied to the buffer portion 72, the external force is absorbed or attenuated by each connecting plate 721. In addition, excessive stress does not occur at the boundary between the side plate 713 and the connecting plate 721, so that a crack in the vertical direction D31 is prevented from being generated at the boundary, and damage to the connecting plate 721 is prevented.

一対の連接板７２１は、湾曲した形状に形成されている。具体的には、図９に示すように、平面視で円弧形状に形成されている。各連接板７２１は、いずれも同じ曲率で湾曲しており、幅方向Ｄ３２の外側の面が凹形状となるように湾曲している。このような形状に形成されているため、各連結板７２１は、前記収納姿勢における開閉部材４６の前記スライド方向と同じ方向、つまり、前後方向Ｄ３２へ撓み易くなる。このような連接板７２１によって筒部７２２と側板７１３とが連接されているため、仮に、トナー容器４０と緩衝部材７０とが包装ケース１１に収納された収納状態で、前後方向Ｄ３３の外力が緩衝部７２に加えられた場合に、その外力は緩衝部７２で吸収又は減衰されるが、前記外力によって連接板７２１が前後方向Ｄ３３に撓まされることにより連接板７２１においても前記外力が吸収又は減衰される。また前後方向Ｄ３３に対して斜め方向の外力が緩衝部７２に加えられた場合は、連接板７２１が撓まされて、連接板７２１を中心に筒部７２２が幅方向Ｄ３２へ変位する。この場合も、連接板７２１において前記外力が吸収又は減衰される。   The pair of connecting plates 721 are formed in a curved shape. Specifically, as shown in FIG. 9, it is formed in an arc shape in plan view. Each connecting plate 721 is curved with the same curvature, and is curved such that the outer surface in the width direction D32 has a concave shape. Since the connecting plate 721 is formed in such a shape, the connecting plate 721 is easily bent in the same direction as the sliding direction of the opening / closing member 46 in the storage posture, that is, in the front-back direction D32. Since the cylindrical portion 722 and the side plate 713 are connected by such a connecting plate 721, the external force in the front-rear direction D33 is buffered in a storage state in which the toner container 40 and the buffer member 70 are stored in the packaging case 11. When applied to the portion 72, the external force is absorbed or attenuated by the buffer portion 72. However, the external force causes the connecting plate 721 to bend in the front-rear direction D33 so that the external force is also absorbed or attenuated by the connecting plate 721. Is done. When an external force oblique to the front-back direction D33 is applied to the buffer portion 72, the connecting plate 721 is bent, and the cylindrical portion 722 is displaced in the width direction D32 around the connecting plate 721. Also in this case, the external force is absorbed or attenuated in the connecting plate 721.

また、図９に示すように、側板７１３の側面には、緩衝部７２の筒部７２２の外周面へ向けて突出する一対の突出リブ７３１が設けられている。一対の突出リブ７３１それぞれは、本発明の第２突出部の一例である。一対の突出リブ７３１それぞれは、連接板７２１の近傍に設けられている。具体的には、一方の連接板７２１の幅方向Ｄ３２の外側へ所定間隔を隔てた位置に一つの突出リブ７３１が設けられており、他方の連接板７２１の幅方向Ｄ３２の外側へ前記所定間隔を隔てた位置にもう一つの突出リブ７３１が設けられている。一対の突出リブ７３１は、上下方向Ｄ３１へ延出しており、上下方向Ｄ３１に長い板状に形成されている。各突出リブ７３１の突出端（先端）は、筒部７２２の外周面まで達しておらず、緩衝部材７０が通常状態にある場合は筒部７２２の外周面に接触していない。しかしながら、仮に、前後方向Ｄ３３の外力が緩衝部７２に加えられた場合に、筒部７２２が前後方向Ｄ３３に変形すると、筒部７２２の外周面は各突出リブ７３１の両方又はいずれか一方の突出端に当接し、突出リブ７３１によって筒部７２２から伝達される力が吸収又は減衰される。   As shown in FIG. 9, a pair of protruding ribs 731 protruding toward the outer peripheral surface of the cylindrical portion 722 of the buffer portion 72 is provided on the side surface of the side plate 713. Each of the pair of projecting ribs 731 is an example of a second projecting portion of the present invention. Each of the pair of projecting ribs 731 is provided near the connecting plate 721. Specifically, one protruding rib 731 is provided at a position outside the width direction D32 of one connecting plate 721 at a predetermined distance, and the predetermined rib is outside the width direction D32 of the other connecting plate 721. Another protruding rib 731 is provided at a position separated by. The pair of protruding ribs 731 extends in the up-down direction D31 and is formed in a plate shape that is long in the up-down direction D31. The protruding end (tip) of each protruding rib 731 does not reach the outer peripheral surface of the cylindrical portion 722, and does not contact the outer peripheral surface of the cylindrical portion 722 when the cushioning member 70 is in a normal state. However, if the cylinder portion 722 is deformed in the front-rear direction D33 when an external force in the front-rear direction D33 is applied to the buffer portion 72, the outer peripheral surface of the cylinder portion 722 may be protruded from one or both of the protruding ribs 731. The force transmitted from the cylindrical portion 722 is absorbed or attenuated by the protruding rib 731 in contact with the end.

このように、一対の連接板７２１が側板７１３に設けられ、また、一対の突出リブ７３１が側板７１３に設けられているため、緩衝部７２の筒部７２２に外力が加えられた場合に、その外力が各連接板７２１及び各突出リブ７３１によって分散される。   As described above, since the pair of connecting plates 721 are provided on the side plate 713 and the pair of projecting ribs 731 are provided on the side plate 713, when an external force is applied to the cylindrical portion 722 of the buffer portion 72, External force is dispersed by each connecting plate 721 and each protruding rib 731.

図６に示すように、緩衝部７２の筒部７２２には、切り欠き７２３が形成されている。切り欠き７２３は、筒部７２２の外周壁に形成されており、筒部７２２の下端から筒部７２２の中心軸方向に沿って上方へ垂直に延びる細幅溝形状である。本実施形態では、筒部７２２の外周壁の前方側の壁面に切り欠き７２３が形成されている。切り欠き７２３は、筒部７２２の下端から筒部７２２の上下方向Ｄ３１の中央付近まで達している。   As shown in FIG. 6, a cutout 723 is formed in the cylindrical portion 722 of the buffer portion 72. The notch 723 is formed in the outer peripheral wall of the cylindrical portion 722, and has a narrow groove shape extending vertically upward from the lower end of the cylindrical portion 722 along the center axis direction of the cylindrical portion 722. In the present embodiment, a notch 723 is formed on the front wall surface of the outer peripheral wall of the cylindrical portion 722. The notch 723 extends from the lower end of the tubular portion 722 to near the center of the tubular portion 722 in the vertical direction D31.

また、図６及び図７（Ａ）に示すように、緩衝部７２の筒部７２２には、一対の切り欠き７２４が形成されている。一対の切り欠き７２４は、筒部７２２の外周壁に形成されており、筒部７２２の下端から上方へ凹む半楕円形状である。本実施形態では、筒部７２２の外周壁の幅方向Ｄ３２の両側の方側の壁面それぞれに切り欠き７２４が形成されている。各切り欠き７２４の切り込み深さは、切り欠き７２３よりも浅く、切り欠き７２３の切り込み深さの概ね半分程度である。   As shown in FIGS. 6 and 7A, a pair of cutouts 724 are formed in the cylindrical portion 722 of the buffer portion 72. The pair of cutouts 724 are formed on the outer peripheral wall of the cylindrical portion 722 and have a semi-elliptical shape that is recessed upward from the lower end of the cylindrical portion 722. In the present embodiment, a cutout 724 is formed on each of the outer peripheral walls of the cylindrical portion 722 on both sides in the width direction D32. The notch depth of each notch 724 is shallower than the notch 723, and is about half of the notch depth of the notch 723.

このように緩衝部材７０が構成されているため、包装体１０において、予期せぬ外力を包装ケース１１に受けた場合でも、その外力が緩衝部７２によって吸収又は減衰される。また、開閉部材４６が収容部７１に非接触状態でカバー部材４２が収容空間７１４に収容されているため、仮に緩衝部７２から衝撃の一部が収容部７１に伝達しても、開閉部材４６に伝わり難い。その結果、包装ケース１１に開閉部材４６のスライド方向と同方向の外力が加えられたとしても、開閉部材４６とトナー排出口４４との間のシールを維持することができ、シールに隙間が生じることが防止できる。その結果、シールの隙間からトナー容器４０内のトナーが外部に漏出することが防止される。   Since the cushioning member 70 is configured as described above, even when an unexpected external force is received by the packaging case 11 in the package 10, the external force is absorbed or attenuated by the buffer 72. Further, since the cover member 42 is accommodated in the accommodation space 714 in a state where the opening / closing member 46 is not in contact with the accommodation portion 71, even if a part of the impact is transmitted from the buffer portion 72 to the accommodation portion 71, It is hard to reach. As a result, even if an external force in the same direction as the sliding direction of the opening and closing member 46 is applied to the packaging case 11, the seal between the opening and closing member 46 and the toner discharge port 44 can be maintained, and a gap is generated in the seal. Can be prevented. As a result, the toner in the toner container 40 is prevented from leaking outside through the gap between the seals.

また、収容部７１の側板７１３と緩衝部７２とが一対の連接板７２１によって連接されているため、緩衝部７２に付与された衝撃や振動等の外力が連接板７２１を通って収容部７１に伝達する際に、連接板７２１によっても吸収又は減衰されるため、収容部７１に外力がより伝わり難くなる。とりわけ、連接板７２１が上述したように湾曲形状に形成されているため、外力を受けた場合に連接板７２１が上下方向Ｄ３１に撓まされやすくなり、連接板７２１における外力の吸収及び減衰による緩衝効果が向上する。   Further, since the side plate 713 of the storage unit 71 and the buffer unit 72 are connected by a pair of connecting plates 721, external force such as shock or vibration applied to the buffer unit 72 passes through the connecting plate 721 to the storage unit 71. At the time of transmission, the external force is more difficult to be transmitted to the accommodation portion 71 because it is also absorbed or attenuated by the connecting plate 721. In particular, since the connecting plate 721 is formed in a curved shape as described above, the connecting plate 721 is easily bent in the up-down direction D31 when an external force is received, and the connecting plate 721 absorbs and damps the external force. The effect is improved.

また、筒部７２２に切り欠き７２３，７２４を形成することにより、緩衝部７２において、適切な緩衝性能を発揮しうる弾性を得ることができる。なお、筒部７２２における弾性は、筒部７２２の外径や厚みによって変化するものであるが、切り欠き７２３，７２４を適宜のサイズや形状に設計することにより、筒部７２２に任意の弾性を持たせることができる。   Further, by forming the cutouts 723 and 724 in the cylindrical portion 722, it is possible to obtain the elasticity of the buffer portion 72 that can exert an appropriate buffering performance. The elasticity of the cylindrical portion 722 varies depending on the outer diameter and thickness of the cylindrical portion 722. By designing the notches 723 and 724 to have an appropriate size and shape, the cylindrical portion 722 can have any elasticity. You can have.

なお、上述の実施形態では、上下方向Ｄ３１を中心軸とする筒部７２２を有する緩衝部７２を例示して説明したが、本発明はこの構成に限られない。例えば、緩衝部７２は、筒部７２２に代えて、開閉部材４６のスライド方向に直交する幅方向Ｄ３２を中心軸とする筒部を有するものであってもよい。この場合、連接板７２１及び突出リブ７３１は、幅方向Ｄ３２へ延出するよう側板７１３に形成される。   In the above-described embodiment, the buffer portion 72 having the cylindrical portion 722 having the central axis in the vertical direction D31 has been described as an example, but the present invention is not limited to this configuration. For example, the buffer portion 72 may have a tubular portion having a central axis in the width direction D32 perpendicular to the sliding direction of the opening / closing member 46, instead of the tubular portion 722. In this case, the connecting plate 721 and the protruding rib 731 are formed on the side plate 713 so as to extend in the width direction D32.

また、上述の実施形態では、筒部７２２と側板７１３とを連接する一対の連接板７２１を例示したが、本発明はこの構成に限られない。例えば、緩衝部材７０は、一つの連接板７２１だけが設けられた構成や、３つ以上の連接板７２１が設けられた構成であってもよい。また、突出リブ７３１についても、少なくとも一つの突出リブ７３１が側面７１３Ｂに設けられていればよい。また、一対の連接板７２１は、互いに平行なものに限られず、また、必ずしも突出リブ７３１と平行なものにも限られない。また、連接板７２１及び突出リブ７３１は、上下方向Ｄ３１に長い板状部材であることに限られず、例えば、連接板７２１及び突出リブ７３１の両方又はいずれか一方が、側板７１３に突設された突起状の部材であってもよい。この場合、連接板７２１又は突出リブ７３１が上下方向Ｄ３１に隔てた状態で複数設けられることが好ましい。つまり、連接板７２１は、緩衝部７２と収容部７１とを連接し、開閉部材４６の前記スライド方向と同方向に撓むことができる構成であればどのような形状、サイズ等であってもよい。また、前記突出リブ７３１は、連接板７２１の近傍に設けられており、側板７１３から緩衝部７２側へ突出する構成であればどのような形状、サイズ等であってもよい。   Further, in the above-described embodiment, a pair of connecting plates 721 that connect the cylindrical portion 722 and the side plate 713 are illustrated, but the present invention is not limited to this configuration. For example, the buffer member 70 may have a configuration in which only one connecting plate 721 is provided, or a configuration in which three or more connecting plates 721 are provided. Further, as for the protruding rib 731, it is sufficient that at least one protruding rib 731 is provided on the side surface 713B. Further, the pair of connecting plates 721 are not limited to those parallel to each other, and are not necessarily limited to those parallel to the protruding ribs 731. Further, the connecting plate 721 and the protruding rib 731 are not limited to being plate-shaped members that are long in the up-down direction D31. For example, both or any one of the connecting plate 721 and the protruding rib 731 protrudes from the side plate 713. It may be a projecting member. In this case, it is preferable that a plurality of connecting plates 721 or projecting ribs 731 are provided in a state separated in the vertical direction D31. That is, the connecting plate 721 connects the buffering portion 72 and the housing portion 71 and can be bent in any shape and size as long as it can bend in the same direction as the sliding direction of the opening / closing member 46. Good. The protruding rib 731 is provided in the vicinity of the connecting plate 721, and may have any shape, size, and the like as long as it protrudes from the side plate 713 toward the buffer unit 72 side.

また、上述の実施形態では、補強部７４の下端部７４１にスリット７４２が形成された構成を例示したが、本発明はこの構成に限られない。例えば、下端部７４１が、リブ７４３，７４４を有しない構成であってもよい。また、上述の実施形態では、補強部７４の下端部７４１が複数の板状部で実現された構成を例示したが、例えば、補強部７４及び下端部７４１は、湾曲形状に形成された概ね円筒状に形成され、下端部７４１の外周面に上下方向Ｄ３１に延びるスリットが形成されたものであってもよい。   Further, in the above-described embodiment, the configuration in which the slit 742 is formed in the lower end portion 741 of the reinforcing portion 74 is illustrated, but the present invention is not limited to this configuration. For example, the lower end 741 may have a configuration without the ribs 743 and 744. Further, in the above-described embodiment, the configuration in which the lower end portion 741 of the reinforcing portion 74 is realized by a plurality of plate-shaped portions has been exemplified. However, for example, the reinforcing portion 74 and the lower end portion 741 are substantially cylindrical formed in a curved shape. A slit may be formed on the outer peripheral surface of the lower end portion 741 so as to extend in the up-down direction D31.
