Description

本発明は、蓋本体と容器内に収容されている内容物に混入すべき添加物を収容したカートリッジとの組み合わせに関する。   The present invention relates to a combination of a lid main body and a cartridge containing an additive to be mixed into contents contained in a container.

下記特許文献１及び２に開示されている如く、容器内に収容されている内容物(通常は液体)に添加すべき添加物(通常は粉体或いは液体)を蓋に収容し、容器内の内容物を消費する際に蓋を適宜に操作することによって、蓋に収容されている添加物を排出して容器内の内容物に混入することができるように構成することが提案されている。   As disclosed in the following Patent Documents 1 and 2, an additive (usually powder or liquid) to be added to the contents (usually liquid) contained in the container is contained in the lid, It has been proposed to configure so that an additive contained in the lid can be discharged and mixed into the contents in the container by appropriately operating the lid when consuming the contents.

特開２００３−２９２０１３号公報JP 2003-292013 A 特開２００５−０８８９９７号公報Japanese Patent Laying-Open No. 2005-088997

而して、上述したとおりの従来の提案には、次のとおりの解決すべき問題がある。第一に、蓋自体に添加物を収容するための収容部を一体に形成しているため、一旦添加物を排出して容器内の内容物に混入すると、比較的高価な蓋全体が再使用不可能になり、経済的でない。第二に、蓋は容器の口頸部を密封するための通常の蓋としても使用され、従って容器の口頸部に装着し続ける故に、長期間に渡って保存され続けると容器内の内容物が、蓋の収容部を規定している部位を透過して添加物に侵入してしまう傾向がある。   Thus, the conventional proposal as described above has the following problems to be solved. First, because the storage part for storing the additive is integrally formed in the lid itself, once the additive is discharged and mixed into the contents of the container, the entire relatively expensive lid is reused. It becomes impossible and not economical. Secondly, the lid is also used as a normal lid to seal the mouth and neck of the container, and therefore keeps being attached to the mouth and neck of the container. However, there is a tendency that it penetrates through the site defining the housing part of the lid and enters the additive.

本発明は上記事実に鑑みてなされたものであり、その主たる技術的課題は、容器内に収容されている内容物に添加物を混入する際に使用され、添加物を排出してもその全体ではなくてその一部のみ（即ちカートリッジのみ）が再使用不可能になるが、その余の部分（即ち蓋本体）は再使用することができ、かくして上記従来の提案に存在する問題が解決された、新規且つ改良された蓋本体とカートリッジとの組み合わせを提供することである。   The present invention has been made in view of the above facts, and its main technical problem is that it is used when the additive is mixed into the contents contained in the container, and even if the additive is discharged, the whole Rather, only a portion (i.e., only the cartridge) becomes non-reusable, but the remaining portion (i.e., the lid body) can be reused, thus solving the problems present in the above-mentioned conventional proposals.

It is a sharp surface that makes an angle of degrees. On the other hand, the protruding amount of the second protrusion 46 is relatively small, and the tip of the second protrusion 46 is arcuate in cross section. As will become clear from the following description, the arc-shaped protrusion 42 and the first protrusion 44 and the second protrusion 46 are the locking protrusions (described further later) disposed on the second member 32 of the cartridge 28. ) To form a locking means. The side wall 40 of the container 34 is also provided with a restricting piece 50 that protrudes outward in the radial direction via a breakable connecting portion 48 made of a thin piece. The connecting portion 48 has an elongated strip shape, and the limiting piece 50 has a rectangular shape. The side wall 40 is further provided with a pair of limiting pieces 52 extending outward in the radial direction with an angular interval of approximately 180 degrees at the upper end of the outer peripheral surface. The upper surface of the limiting piece 52 extends downward in the radial direction and the lower surface extends substantially horizontally.

図２及び図４を参照して説明を続けると、カートリッジ２８の第二の部材３２は上面及び下面が開口されている円筒体５４から構成されている。円筒体５４の外周面には、周方向に等間隔をおいて半径方向に突出する４個の被支持突条５５が形成されている。円筒体５４の内周面下端部には半径方向内方に延出する円環状底壁５６が形成されている。図１０を参照することによって明確に理解されるとおり、底壁５６の下面には下方に突出する環状シール片５７が形成されている。円筒体５４は底壁５６を越えて下方に突出している。底壁５６は周方向に等間隔をおいて複数個、図示の場合は４個、の領域において半径方向内方に延出せしめられており、かかる延出部の各々には上方に突出する弧状片５８が形成されている。底壁５６の上面には、弧状片５８よりも半径方向外側において上方に突出する密封リング６０も形成されている。図１０を参照することによって明確に理解される如く、弧状片５８の突出高さはリング６０の突出高さよりも大きく、図示の実施形態においては弧状片５８の突出高さはリング６０の突出高さの略２倍に設定されている。底壁５６には、更に、隣接する弧状片５８間の領域において、半径方向中心から底壁５６の内周縁まで放射状に延びる４個の放射片６２が付設されている。そして、４個の放射片６２の半径方向内側部上面には切断手段６４が配設されている。図示の実施形態における切断手段６４は、等角度間隔(図示の場合は９０度の角度間隔)をおいて配設された複数個（図示の場合は４個）の切断片６５から構成されている。４個の切断片６５は全体として十字状の横断面形状を有し、切断片６５の各々は半径方向中心に位置する鋭い頂点から半径方向外方に向かって下方に傾斜して延びる４個の鋭い切断縁６６を有する。切断縁６６の各々は夫々放射片６２の各々に沿って延在する。切断手段６４の半径方向外側縁６８は放射片６２の上面まで実質上鉛直に垂下せしめられている。   Continuing the description with reference to FIGS. 2 and 4, the second member 32 of the cartridge 28 is constituted by a cylindrical body 54 whose upper and lower surfaces are opened. Four supported ridges 55 are formed on the outer peripheral surface of the cylindrical body 54 so as to protrude in the radial direction at equal intervals in the circumferential direction. An annular bottom wall 56 extending inward in the radial direction is formed at the lower end portion of the inner peripheral surface of the cylindrical body 54. As clearly understood by referring to FIG. 10, an annular seal piece 57 projecting downward is formed on the lower surface of the bottom wall 56. The cylindrical body 54 protrudes downward beyond the bottom wall 56. A plurality of bottom walls 56 are equally spaced in the circumferential direction, and in the illustrated case, four are extended radially inwardly, and each of the extending portions has an arc shape protruding upward. A piece 58 is formed. A sealing ring 60 is also formed on the upper surface of the bottom wall 56 so as to protrude upward in the radial direction outside the arc-shaped piece 58. As clearly understood by referring to FIG. 10, the protruding height of the arc-shaped piece 58 is larger than the protruding height of the ring 60, and in the illustrated embodiment, the protruding height of the arc-shaped piece 58 is the protruding height of the ring 60. It is set to approximately twice that. The bottom wall 56 is further provided with four radiating pieces 62 extending radially from the radial center to the inner peripheral edge of the bottom wall 56 in the region between the adjacent arc-shaped pieces 58. A cutting means 64 is disposed on the upper surface of the radially inner portion of the four radiation pieces 62. The cutting means 64 in the illustrated embodiment is composed of a plurality (four in the illustrated example) of cutting pieces 65 disposed at an equal angular interval (in the illustrated case, an angular interval of 90 degrees). . The four cut pieces 65 have a cross-shaped cross-sectional shape as a whole, and each of the cut pieces 65 extends from the sharp apex located at the center in the radial direction to be inclined downward in the radial direction downward. It has a sharp cutting edge 66. Each of the cutting edges 66 extends along each of the radiation pieces 62. The radially outer edge 68 of the cutting means 64 is suspended substantially vertically to the upper surface of the radiation piece 62.

円筒体５４の内周面には、周方向に等間隔をおいて半径方向内側に突出する複数個、図示の場合は４個、の係止突起７０が配設されている。図６に明確に図示する如く、係止突起７０の片端面（図６において時計方向前端面）７２は円筒体５４の内周面に対して略９０度の角度をなす切り立った面であり、係止突起７０の他端面(図６において時計方向後端面)７４は緩やかな弧状面である。後の説明から明らかになるとおり、係止突起７０は第一の部材３０の収容体３４に形成されている弧状突起４２並びに第一の突条４４及び第二の突条４６と協働してロック手段を構成する。円筒体５４の内周面には、更に、係止突起７０よりも下方において周方向に間隔をおいて半径方向に突出する複数個、図示の場合は４個、の弧状係止片７６も配設されている。図６に明確に図示する如く、弧状係止片７６の各々は係止突起７０の各々に対して図６において時計方向前方に幾分変位せしめられている。   On the inner peripheral surface of the cylindrical body 54, a plurality of locking projections 70 (in the illustrated case, four) projecting radially inward at equal intervals in the circumferential direction are arranged. As clearly shown in FIG. 6, one end surface (clockwise front end surface in FIG. 6) 72 of the locking projection 70 is a sharp surface that forms an angle of approximately 90 degrees with respect to the inner peripheral surface of the cylindrical body 54. The other end surface (clockwise rear end surface in FIG. 6) 74 of the locking projection 70 is a gentle arcuate surface. As will be apparent from the following description, the locking protrusion 70 cooperates with the arc-shaped protrusion 42 formed on the housing 34 of the first member 30 and the first protrusion 44 and the second protrusion 46. Constitutes locking means; On the inner peripheral surface of the cylindrical body 54, a plurality of, in the illustrated case, four arcuate locking pieces 76 projecting in the radial direction at intervals in the circumferential direction below the locking projections 70 are also arranged. It is installed. As clearly shown in FIG. 6, each of the arcuate locking pieces 76 is somewhat displaced clockwise in FIG. 6 with respect to each of the locking projections 70.

次に、上述したとおりの組み合わせの使用様式について説明する。カートリッジ２８の第一の部材３０における収容体３４を倒立状態、即ち開口されている下面を上方に向けた状態にせしめて、収容体３４に粉体或いは液体でよい添加物（図示していない）を収容する。次いで、収容体３４の側壁４０の下端に閉塞片３６を接合して収容体３４の下面を閉塞する。しかる後に、第一の部材３０と第二の部材３２とを組み合わせてカーリッジ２８を構成する。詳述すると、図５に図示する如く、第二の部材３２を構成する円筒体５４の開口された上面を通して、第一の部材３０即ち下面に閉塞片３６が接合された収容体３４の下部を円筒体５４内に挿入する。この際には、収容体３４の下端に形成されている４個の弧状突起４２を円筒体５４の内周面に形成されている４個の係止突起７０の間に位置せしめ、かくして係止突起７０の間を通過せして弧状突起４２を係止突起７０よりも下方に位置せしめる。円筒体５４内への収容体３４の挿入は、収容体３４に配設されている制限片５０が円筒体５４の上端に当接することによって制限され、収容体３４の弧状突起４２は円筒体５４の内周面に形成されている係止突起７０よりは下方に位置するが弧状係止片７６よりは上方に位置する。次いで、円筒体５４に対して収容体３４を上方から見て時計方向或いは反時計方向に回転せしめる。図６を参照することによって明確に理解される如く、収容体３４に配設されている第一の突条４４は、その両側面が切り立った面であるので円筒体５４に配設されている係止突起７０の両端面に当接して係止されるが、収容体３４に配設されている第二の突条４６の突出量は比較的小さく且つ先端面は横断面において弧状である故に、係止突起７０の切り立った片端面７２には当接して係止されるが、係止突起７０の緩やかな他端面７４には係止することなく、弾性的に他端面７４を越えて係止突起７０に乗り上がり係止突起７０を乗り越えることができる。かような次第であるので、図６を参照することによって理解される如く、円筒体５４に対する収容体３４の回転は、収容体３４に配設されている弧状突起４２が円筒体５４に配設されている係止突起７０の下方に位置する状態で停止せしめられる。かかる状態において、円筒体５４に対して収容体３４が上方に変位せんとすると、弧状突起４２が係止突起７０に当接し、かくして収容体３４の上方への変位が防止され、円筒体５４に対して収容体３４が上方に離脱することが阻止される。収容体３４の制限片５０が円筒体５４の上端に当接した時点において、収容体３４の弧状突起４２は円筒体５４の弧状係止片７６よりも幾分上方に位置する故に、図５に図示するごとく円筒体５４に対して収容体３４が幾分傾斜し、弧状突起４２の１個が弧状係止片７６の１個に当接せしめられる。第一の部材３０と第二の部材３２から構成されたカートリッジ２８は図５に図示する状態に組み合わされて、例えば合成樹脂フィルムから構成された袋(図示していない)内に密封包装されて販売される。   Next, the usage mode of the combination as described above will be described. The container 34 in the first member 30 of the cartridge 28 is in an inverted state, that is, an open lower surface is directed upward, and the container 34 may be an additive (not shown) that may be powder or liquid. To accommodate. Next, the closing piece 36 is joined to the lower end of the side wall 40 of the container 34 to close the lower surface of the container 34. Thereafter, the first member 30 and the second member 32 are combined to form the cartridge 28. More specifically, as shown in FIG. 5, the lower part of the container 34 in which the closing piece 36 is joined to the first member 30, that is, the lower surface, through the opened upper surface of the cylindrical body 54 constituting the second member 32. Insert into the cylindrical body 54. At this time, the four arc-shaped protrusions 42 formed on the lower end of the housing 34 are positioned between the four locking protrusions 70 formed on the inner peripheral surface of the cylindrical body 54, and thus are locked. The arc-shaped protrusion 42 is positioned below the locking protrusion 70 by passing between the protrusions 70. The insertion of the container 34 into the cylindrical body 54 is restricted by the restriction piece 50 disposed in the container 34 coming into contact with the upper end of the cylindrical body 54, and the arcuate protrusion 42 of the container 34 is formed in the cylindrical body 54. It is positioned below the locking protrusion 70 formed on the inner peripheral surface of the, but is positioned above the arcuate locking piece 76. Next, the container 34 is rotated clockwise or counterclockwise with respect to the cylindrical body 54 as viewed from above. As can be clearly understood by referring to FIG. 6, the first protrusion 44 disposed in the container 34 is disposed in the cylindrical body 54 because the both side surfaces of the first protrusion ridge 44 are erected surfaces. The two protrusions 46 disposed on the container 34 are relatively small in protrusion amount and are in an arc shape in the cross section. The locking projection 70 is brought into contact with and locked to the one end surface 72, but the locking projection 70 is elastically beyond the other end surface 74 without being locked to the gentle other end surface 74 of the locking projection 70. It can ride on the stop protrusion 70 and can get over the stop protrusion 70. Therefore, as understood by referring to FIG. 6, the rotation of the container 34 relative to the cylindrical body 54 is caused by the arc-shaped protrusion 42 disposed on the container 34 being disposed on the cylindrical body 54. It is made to stop in the state located under the latching protrusion 70 currently made. In this state, when the container 34 is displaced upward with respect to the cylindrical body 54, the arc-shaped protrusion 42 contacts the locking protrusion 70, and thus the upward displacement of the container 34 is prevented. On the other hand, the container 34 is prevented from separating upward. When the limiting piece 50 of the container 34 abuts the upper end of the cylindrical body 54, the arc-shaped protrusion 42 of the container 34 is positioned somewhat above the arc-shaped locking piece 76 of the cylindrical body 54. As shown in the drawing, the container 34 is slightly inclined with respect to the cylindrical body 54, and one of the arc-shaped protrusions 42 is brought into contact with one of the arc-shaped locking pieces 76. The cartridge 28 composed of the first member 30 and the second member 32 is combined in the state shown in FIG. 5 and sealed and packaged in a bag (not shown) composed of a synthetic resin film, for example. Sold.

カートリッジ２８を購入した消費者が収容体３４内に収容されている添加物を消費する際の典型的消費様式は、次のとおりである。最初に、カートリッジ２８の第一の部材３０における収容体３４の側壁４０に付設されている破断可能な連結部４８を破断して制限片５０を除去する。かくすると、図７に図示する如く、第二の部材３２に対する第一の部材３０の若干の傾斜が解消されて、収容体３４の４個の弧状突起４２が円筒体５４の４個の弧状係止片７６に当接せしめられる。しかる後に、蓋本体２の外蓋６を図１に図示する開位置にせしめ、図７に図示する如く、主部４の開口されている上面を通して主部４内にカートリッジ２８を挿入する。主部４内へのカートリッジ２８の挿入は、円筒体５４の外周面に形成されている被支持突条５５が主部４の内周面に形成されている支持突条１６に当接することによって、そしてまた収容体３４の側壁４０の外周面上端部に形成されている一対の限定片５２が主部４の上端縁に当接することによって、制限される。次いで、蓋本体２の外蓋６を図７に図示する閉位置にせしめる。その一方で、例えば天然水の如き液体である内容物を収容している適宜の容器、例えばポリエチレンテレフタレート製の容器の口頸部７８(図８)に装着されている容器蓋(図８にそのタンパーエビデント裾部８０のみを図示している)を、そのタンパーエビデント裾部８０のみを残留せしめて、口頸部７８から離脱せしめる。周知の形態でよい容器の口頸部７８の外周面には雄螺条８２とこの雄螺条８２の下方に位置する係止あご部８４とが形成されている。容器蓋は、天面壁とこの天面壁の周縁から垂下するスカート壁とを有し、スカート壁には周方向破断ラインが形成されていて、スカート壁は周方向破断ラインよりも上方の主部と周方向破断ラインよりも下方のタンパーエビデント裾部８０とに区画されており、スカート壁の主部内周面には口頸部７８の雄螺条に螺合せしめられる雌螺条が形成され、タンパーエビデント裾部８０の内周面には口頸部７８の係止あご部８４に係止される係止手段が形成されており、口頸部７８を開封する際には周方向破断ラインが破断されている。 A typical consumption mode when a consumer who purchases the cartridge 28 consumes the additive contained in the container 34 is as follows. First, the breakable connecting portion 48 attached to the side wall 40 of the container 34 in the first member 30 of the cartridge 28 is broken to remove the limiting piece 50. As a result, as shown in FIG. 7, the slight inclination of the first member 30 with respect to the second member 32 is eliminated, and the four arc-shaped protrusions 42 of the container 34 have four arc-shaped engagements of the cylindrical body 54. It is brought into contact with the stop piece 76. Thereafter, the outer lid 6 of the lid body 2 is moved to the open position shown in FIG. 1, and the cartridge 28 is inserted into the main portion 4 through the open upper surface of the main portion 4 as shown in FIG. The cartridge 28 is inserted into the main portion 4 when the supported ridge 55 formed on the outer peripheral surface of the cylindrical body 54 abuts on the support ridge 16 formed on the inner peripheral surface of the main portion 4. Further, the pair of limiting pieces 52 formed on the upper end portion of the outer peripheral surface of the side wall 40 of the container 34 are limited by contacting the upper end edge of the main portion 4. Next, the outer lid 6 of the lid body 2 is moved to the closed position shown in FIG. On the other hand, for example, a container lid (see FIG. 8) that is attached to a mouth and neck portion 78 (FIG. 8) of an appropriate container containing a liquid content such as natural water, for example, a container made of polyethylene terephthalate. Only the tamper evidence skirt 80 is shown), and only the tamper evidence skirt 80 is left to leave the mouth and neck 78. A male thread 82 and a locking jaw 84 positioned below the male thread 82 are formed on the outer peripheral surface of the mouth-and-neck part 78 of the container, which may be in a known form. Container lid and a skirt wall hanging down the top panel wall from the peripheral edge of the top wall, the skirt wall is formed in the circumferential direction breaking line, and the upper main portion than the skirt wall circumferentially broken line A tamper-evidence skirt 80 below the circumferential break line is defined, and a female thread that is screwed to the male thread of the mouth-and-neck 78 is formed on the inner peripheral surface of the main part of the skirt wall. The tamper evidence hem 80 has an inner peripheral surface formed with a locking means that is locked to the locking jaw 84 of the mouth-and-neck portion 78. When the mouth-and-neck portion 78 is opened, a circumferential break line is formed. There has been broken.

次いで、図８に図示する如く、カートリッジ２８を収容した蓋本体２を口頸部７８に被嵌し、図８において上方から見て時計方向に蓋本体２を回転せしめて、蓋本体２の主部４の内周面下端部に形成されている雌螺条１４を口頸部７８の雄螺条８２に螺合せしめる。雌螺条１４と雄螺条８２との螺合の進行に従って、口頸部７８に対して蓋本体２が下降せしめられると、カートリッジ２８の第二の部材３２を構成する円筒体５４の下面に配設されているシール片５７が口頸部７８内に進入すると共に、円筒体５４の底壁５６の下端が口頸部７８の頂面に当接せしめられ、かくして口頸部７８に対してカートリッジ２８が更に下降することが阻止される(図１０も参照されたい)。口頸部７８に対する蓋本体２の下降が進行し、蓋本体２が図８に図示する位置まで下降せしめられると、蓋本体２の外蓋６における天面壁１８の内面がカートリッジ２８の第一の部材３０における収容体３４の上面壁３８に当接せしめられる。   Next, as shown in FIG. 8, the lid body 2 containing the cartridge 28 is fitted on the mouth and neck portion 78, and the lid body 2 is rotated clockwise as viewed from above in FIG. The female thread 14 formed at the lower end of the inner peripheral surface of the portion 4 is screwed into the male thread 82 of the mouth-and-neck section 78. When the lid main body 2 is lowered with respect to the mouth-and-neck portion 78 as the screwing of the female screw 14 and the male screw 82 proceeds, the lower surface of the cylindrical body 54 constituting the second member 32 of the cartridge 28 is lowered. The disposed seal piece 57 enters the mouth and neck portion 78, and the lower end of the bottom wall 56 of the cylindrical body 54 is brought into contact with the top surface of the mouth and neck portion 78. The cartridge 28 is prevented from further lowering (see also FIG. 10). When the lid body 2 descends with respect to the mouth and neck portion 78 and the lid body 2 is lowered to the position shown in FIG. 8, the inner surface of the top wall 18 of the outer lid 6 of the lid body 2 is the first surface of the cartridge 28. The member 30 is brought into contact with the upper surface wall 38 of the container 34.

蓋本体２の回転を続けて口頸部７８に対する蓋本体２の下降を続けると、カートリッジ２８の第二の部材３２は口頸部７８に対して更に下降することが阻止されるが、カートリッジ２８の第一の部材３０は、外蓋２の天面壁１８が収容体３４の上面壁３８を下方に強制することによって蓋本体２の下降に付随して強制的に下方に移動せしめられる。従って、円筒体５４に対して収容体３４が強制的に下降せしめられ、収容体３４の弧状突起４２は円筒体５４の弧状係止片７６を弾性的に乗り越える。図９と共に図１０を参照することによって明確に理解される如く、円筒体５４に対して収容体３４が下降せしめられると、円筒体５４の切断手段６４が、収容体３４の側壁４０の下端に接合されている閉塞片３６に作用して、閉塞片３６の中央部を十字状に破断する。円筒体５４に対して収容体３４が図９及び図１０に図示する位置まで下降せしめられると、収容体３４の下端に配設されている弧状突起４２が円筒体５４の底壁５６の上面に当接せしめられ、収容体３４の側壁４０の下端部内周面は上方に変位せしめられた閉塞片３６を介して円筒体５４のリング６０の外周面に密接せしめられ、これによって収容体３４の下端外周縁部が密封される。切断手段６４によって切断された閉塞片３６は、図１０に図示する如く、リング６０及び弧状片５８に案内されて上方に変位され、かくして収容体３４内から容器の口頸部７８内に通じる排出路が生成され、収容体３４内に収容されていた添加物が容器内に収容されている内容物に混入される。収容体３４内に残留する添加物を充分に排出せしめるためには、図９に図示する状態において容器を適宜に振ることが意図され得るが、かくした場合リング６０が閉塞片３６を介して収容体３４の側壁４０の下端部内周面に密接せしめられている故に、容器の内容物が収容体３４の外側に流出することが充分に防止され、蓋本体２が内容物によって汚染されることはない。   If the lid body 2 continues to rotate and the lid body 2 continues to descend with respect to the mouth and neck portion 78, the second member 32 of the cartridge 28 is prevented from further descending with respect to the mouth and neck portion 78. The first member 30 of the outer lid 2 is forcibly moved downward along with the lowering of the lid body 2 by forcing the top wall 18 of the outer lid 2 downward of the upper wall 38 of the container 34. Therefore, the container 34 is forcibly lowered with respect to the cylindrical body 54, and the arc-shaped protrusion 42 of the container 34 elastically rides over the arc-shaped locking piece 76 of the cylindrical body 54. As clearly understood by referring to FIG. 10 together with FIG. 9, when the container 34 is lowered with respect to the cylindrical body 54, the cutting means 64 of the cylindrical body 54 is placed at the lower end of the side wall 40 of the container 34. It acts on the joined closing piece 36 to break the central portion of the closing piece 36 into a cross shape. When the container 34 is lowered with respect to the cylindrical body 54 to the position shown in FIGS. 9 and 10, the arc-shaped protrusion 42 disposed at the lower end of the container 34 is formed on the upper surface of the bottom wall 56 of the cylindrical body 54. The inner peripheral surface of the lower end portion of the side wall 40 of the accommodating body 34 is brought into contact with the outer peripheral surface of the ring 60 of the cylindrical body 54 via the closing piece 36 displaced upward, and thereby the lower end of the accommodating body 34 is contacted. The outer peripheral edge is sealed. As shown in FIG. 10, the closing piece 36 cut by the cutting means 64 is guided by the ring 60 and the arc-shaped piece 58 and is displaced upward, and is thus discharged from the inside of the container 34 into the mouth neck 78 of the container. A path is generated, and the additive contained in the container 34 is mixed into the contents contained in the container. In order to sufficiently discharge the additive remaining in the container 34, it may be intended to shake the container appropriately in the state shown in FIG. 9, but in this case, the ring 60 is accommodated via the closing piece 36. Since the container 34 is in close contact with the inner peripheral surface of the lower end portion of the side wall 40, the contents of the container are sufficiently prevented from flowing out of the container 34, and the lid body 2 is not contaminated by the contents. Absent.

収容体３４内に収容されていた添加物の実質上全てが排出されて容器内に収容されている内容物に混入された後においては、蓋本体２を図９において上方から見て反時計方向に回転せしめて雄螺条８２と雌螺条１４の螺合を漸次解除し、蓋本体２及びこれに収容されているカートリッジ２８を容器の口頸部７８から離脱せしめる。蓋本体２の外蓋６を開位置にせしめて蓋本体２から取り出されたカートリッジ２８は再使用されることなく破棄されるが、蓋本体２は更に他の新しいカートリッジ２８と組み合わせて再使用することができる。一方、容器内に収容されている、添加物が混入されている内容物については、必要ならばタンパーエビデント裾部８０のみを残留せしめて口頸部７８から離脱した容器蓋を再び口頸部７８に装着して口頸部７８を仮密封した後に容器を適宜に振って添加物を内容物に充分に混合し、次いで容器蓋を口頸部７８から再び離脱した後に、消費することもできる。   After substantially all of the additive contained in the container 34 has been discharged and mixed into the contents contained in the container, the lid body 2 is counterclockwise as viewed from above in FIG. , The male screw 82 and the female screw 14 are gradually disengaged, and the lid body 2 and the cartridge 28 accommodated in the lid main body 2 and the cartridge 28 accommodated therein are detached from the mouth-and-neck portion 78 of the container. The cartridge 28 removed from the lid body 2 with the outer lid 6 of the lid body 2 in the open position is discarded without being reused, but the lid body 2 is further reused in combination with another new cartridge 28. be able to. On the other hand, with respect to the contents contained in the container and containing the additive, if necessary, the container lid separated from the mouth-and-neck part 78 with only the tamper-evidence hem part 80 remaining is removed. After the mouth-and-neck portion 78 is temporarily sealed after being attached to 78, the container is shaken appropriately so that the additive is sufficiently mixed with the contents, and then the container lid is removed from the mouth-and-neck portion 78 and then consumed. .
