Description

本発明は、容器内に収容されている液体の如き内容物に混入すべき添加物を収容したカートリッジに関する。 The present invention relates to a cartridge containing an additive to be mixed into a content such as a liquid 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、内容物を収容している容器とは別個に添加物を流通せしめることができない。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由来の水分が、蓋の収容部を規定している部位を透過して添加物が湿気により劣化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, since the storage portion for storing the additive is integrally formed in the lid itself, the additive cannot be distributed separately from the container storing the contents. 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. There is a tendency that the moisture derived from the permeation passes through the part defining the housing portion of the lid and the additive is deteriorated by moisture.

上記のとおりの事実に鑑み、本発明者等は、先に、特願２０１１−１１７３９３において、通常の蓋によって口頸部が密封されている容器とは別個に流通せしめられ、口頸部が開封された容器に適用して容器内の内容物に添加物を添加することができる、新規且つ改良されたカートリッジを提示した。かかるカートリッジは添加物を収容する第一の部材と切断手段を備えた第二の部材とから構成されている。第一の部材は、円形上面壁とこの上面壁の周縁から垂下する円筒形側壁とを有し、下面は開口されている収容体と、この収容体の下面を閉塞するための切断可能な閉塞片とを備え、収容体に添加物を収容した後に収容体の下面に閉塞片が付設されて収容体の下面が閉塞される。第二の部材は、上面及び下面は開口されている円筒体から構成されており、切断手段は円筒体の内側に周方向に間隔をおいて配設された複数個の切断片から構成されており、切断片の各々は円筒体の中心に位置する内側先端から半径方向外方に向かって下方に傾斜して延び、次いで半径方向外方に向かって上方に傾斜して外側先端まで延びる放射状切断縁を有する。収容体の外周面には被係止手段が配設され、円筒体の内周面には上方係止手段と下方係止手段とが配設されており、第一の部材を円筒体の上面を通して該円筒体内に、閉塞片が切断手段よりも上方に位置する組み合せ位置まで部分的に挿入すると、被係止手段と上方係止手段とが協働して、第一の部材が該円筒体に対して上方に移動することが阻止される。第一の部材を円筒体に対して組み合せ位置を超えて排出位置まで下降せしめると、切断手段が閉塞片に作用して閉塞片を切断し、収容体内に収容されていた添加物が収容体の下面から排出されると共に、被係止手段と下方係止手段とが協働して第一の部材が円筒体に対して上方に移動することが阻止される。 In view of the facts as described above, the present inventors previously circulated in the Japanese Patent Application No. 2011-117393 separately from the container in which the mouth and neck are sealed with a normal lid, and the mouth and neck are opened. A new and improved cartridge has been presented that can be applied to a packaged container to add additives to the contents in the container. Such a cartridge is composed of a first member for containing an additive and a second member having a cutting means. The first member has a circular upper surface wall and a cylindrical side wall depending from the periphery of the upper surface wall, and a lower surface of the container is opened, and a severable blockage for closing the lower surface of the container. After the additive is stored in the container, a closing piece is attached to the lower surface of the container to close the lower surface of the container. The second member is composed of a cylindrical body having an upper surface and a lower surface opened, and the cutting means is composed of a plurality of cutting pieces arranged at intervals in the circumferential direction inside the cylindrical body. Each of the cutting pieces extends from the inner tip located at the center of the cylindrical body in a downwardly inclined manner toward the radially outward direction, and then inclines radially outwardly in an upwardly extending manner to the outer tip. Has an edge. Locking means is disposed on the outer peripheral surface of the container, and upper locking means and lower locking means are disposed on the inner peripheral surface of the cylindrical body. The first member is an upper surface of the cylindrical body. When the blocking piece is partially inserted into the cylindrical body through the combination position where the closing piece is located above the cutting means, the locked means and the upper locking means cooperate with each other so that the first member becomes the cylindrical body. Is prevented from moving upward. When the first member is moved down to the discharge position beyond the combination position with respect to the cylindrical body, the cutting means acts on the closing piece to cut the closing piece, and the additive contained in the containing body is removed from the containing body. While being discharged from the lower surface, the locked member and the lower locking member cooperate to prevent the first member from moving upward with respect to the cylindrical body.

而して、本発明者等の経験によれば、本発明者等が提示した上述したとおりのカートリッジも未だ充分に満足し得るものではなく、切断手段の作用によって閉塞片を切断して閉塞片を適宜に変位せしめ、かくして収容体内に収容されている添加物を排出する際に、過大な力を必要とする傾向があることが判明している。 Thus, according to the experience of the present inventors, the cartridge as presented above by the present inventors is still not sufficiently satisfactory, and the closed piece is cut by the action of the cutting means. It has been found that there is a tendency to require an excessive force when the additive is displaced appropriately and thus the additive contained in the container is discharged.

従って、本発明の主たる技術的課題は、本発明者等が提示して上述したとおりのカートリッジに更に改良を加え、過大な力を必要とすることなく切断手段の作用によって閉塞片を切断して閉塞片を適宜に変位せしめることができるカートリッジを提供することである。 Therefore, the main technical problem of the present invention is to further improve the cartridge as presented above by the present inventors, and to cut off the closing piece by the action of the cutting means without requiring excessive force. It is an object of the present invention to provide a cartridge capable of appropriately displacing the closing piece.

本発明によれば、切断手段を構成する切断片の各々に、円筒体の中心に位置する内側先端から半径方向外方に向かって下方に傾斜して延び、次いで半径方向外方に向かって上方に傾斜して外側先端まで延びる放射状切断縁に加えて、放射状切断縁の外側先端乃至その近傍から周方向片側のみに延びる周方向切断縁を付加することによって、上記主たる技術的課題が達成される。 According to the present invention, each of the cutting pieces constituting the cutting means extends from the inner tip located at the center of the cylindrical body so as to be inclined downward in the radial direction and then upward in the radial direction. In addition to the radial cutting edge inclined to the outer tip, the main technical problem is achieved by adding a circumferential cutting edge extending only from the outer tip of the radial cutting edge or its vicinity to one side in the circumferential direction. .

カートリッジを購入した消費者が収容体６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。図５に図示する如く、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７４に装着されている容器蓋（図示していない）を口頸部７４から離脱せしめる。周知の形態でよい容器の口頸部７４の外周面には雄螺条７６が形成されている。次いで、図５に図示する如く、第二の部材４を構成する円筒体３４の下部４０を容器の口頸部７４に被嵌し、図５において上方から見て時計方向に第二の部材４(及び第一の部材２)を回転せしめて、円筒体３４の下部４０の内周面に形成されている雌螺条５８を口頸部７４の雄螺条７６に螺合せしめる。雌螺条５８と雄螺条７６とを所要とおりに螺合せしめると、図５に図示する如く、円筒体３４の上部３６の内周面下端に配設されている環状フランジ６４の下面が口頸部７４の頂面に当接せしめられ、そしてまた円筒体３４の上部３６の下端から垂下する環状シール片６０が口頸部７４の外周面上端部に密接せしめられ、これによって口頸部７４がシールされる。 A typical consumption mode when a consumer who purchases a cartridge consumes the additive contained in the container 6 is as follows. As shown in FIG. 5, a container lid (not shown) attached to the neck portion 74 of an appropriate container containing a liquid content such as natural water, for example, a container made of polyethylene terephthalate. ) Is removed from the mouth and neck 74. A male thread 76 is formed on the outer peripheral surface of the mouth / neck part 74 of the container which may be in a known form. Next, as shown in FIG. 5, the lower portion 40 of the cylindrical body 34 constituting the second member 4 is fitted on the mouth and neck portion 74 of the container, and the second member 4 is clockwise when viewed from above in FIG. 5. (And the first member 2) is rotated so that the female thread 58 formed on the inner peripheral surface of the lower portion 40 of the cylindrical body 34 is screwed into the male thread 76 of the mouth-and-neck portion 74. When the female thread 58 and the male thread 76 are screwed together as required, the lower surface of the annular flange 64 disposed at the lower end of the inner peripheral surface of the upper portion 36 of the cylindrical body 34 is opened as shown in FIG. An annular seal piece 60 that is brought into contact with the top surface of the neck portion 74 and also hangs from the lower end of the upper portion 36 of the cylindrical body 34 is brought into close contact with the upper end portion of the outer peripheral surface of the mouth neck portion 74, thereby. Is sealed.

次いで、第一の部材２における収容体６の外周面に付設されている弧状片１８を、その上流端部２０を把持して半径方向外方に強制して接続片２４の半径方向内側端の易破断部を破断し、次いで上流端部２０を半径方向外方及び周方向下流側に向けて強制して接続壁２６の薄肉部位を破断することによって、収容体６から離脱せしめる。しかる後に、例えば収容体６の上面壁１０を押圧することによって第一の部材２を図６に図示する排出位置まで下降せしめる。この際には、第一の部材２の被係止手段２８を構成する突条３０が下方係止手段５２を構成する係止突条５６を弾性的に乗り越えて突条３０が係止突条５６の下方に位置し、これによって第二の部材４に対して第一の部材２が図６に図示する排出位置よりも上方に移動することが阻止される。加えて、第一の部材２が図６に図示する排出位置まで下降せしめられる際には、第二の部材４に配設されている切断手段６２が、第一の部材２を構成する収容体６の側壁１２の下端に接合されている閉塞片８に作用して閉塞片８を切断する。更に詳しくは、切断手段６２を構成する切断片６６の各々は、半径方向に離隔して位置する内側先端６８ａ及び外側先端６８ｂから閉塞片８に作用し始め、これによって閉塞片８の弛みを充分に抑制し、充分容易に且つ過大な力を必要とすることなく閉塞片８の破断を開始する。そして、切断片６６の放射状切断縁６８によって閉塞片８によって複数個の放射状切り目を生成すると共に周方向切断縁７０によって閉塞片８に複数個の周方向切れ目を生成する。そして、閉塞片８の上記のとおりの切断が進行した後に、複数個の弧状拘束片７２が閉塞片８に作用して閉塞片８を上方に変位し、かくして収容体６内から容器の口頸部７４内に通じる排出路が生成され、収容体６内に収容されていた内容物即ち添加物（図示していない）が容器内に収容されている内容物に混入される。閉塞片８には複数個の放射状切れ目と共に複数個の周方向切れ目が生成されている故に、拘束片７２の作用によって充分容易に閉塞片８を上方に変位せしめて所要排出路を生成することができる。図６に明確に図示するとおり、第二の部材４に対して第一の部材２が図６に図示する排出位置まで下降せしめられると、第一の部材２の収容体６の側壁１２の外周面下部に形成されている環状シール突条３２が第二の部材４を構成する円筒体３４の上部３６の内周面下部に密接せしめられ、かくして収容体６と円筒体３４との間が密封される。また、収容体６の側壁１２に配設されている突出片１６の下端が円筒体３４の上部３６に形成されているスリット４２の下端に当接乃至近接し、これによって消費者は第二の部材４が第一の部材２に対して図６に図示する排出位置まで下降せしめられたことを視覚的に確認することができる。 Next, the arc-shaped piece 18 attached to the outer peripheral surface of the container 6 in the first member 2 is gripped by the upstream end portion 20 and forced outward in the radial direction, so that the radially inner end of the connection piece 24 is The easily breakable portion is broken, and then the upstream end portion 20 is forced radially outward and circumferentially downstream to break the thin portion of the connection wall 26 to be detached from the container 6. Thereafter, for example, the first member 2 is lowered to the discharge position shown in FIG. 6 by pressing the upper surface wall 10 of the container 6. At this time, the ridge 30 constituting the locked means 28 of the first member 2 elastically climbs over the locking ridge 56 constituting the lower locking means 52 so that the ridge 30 is locked. 56, thereby preventing the first member 2 from moving above the discharge position shown in FIG. 6 relative to the second member 4. In addition, when the first member 2 is lowered to the discharge position shown in FIG. 6, the cutting means 62 disposed on the second member 4 is a container that constitutes the first member 2. 6 acts on the closing piece 8 joined to the lower end of the side wall 12 to cut the closing piece 8. More specifically, each of the cutting pieces 66 constituting the cutting means 62 starts to act on the closing piece 8 from the inner tip 68a and the outer tip 68b that are radially spaced from each other, thereby sufficiently relaxing the closing piece 8. And the breakage of the closing piece 8 is started sufficiently easily and without requiring an excessive force. A plurality of radial cuts are generated by the closing piece 8 by the radial cutting edges 68 of the cutting piece 66 and a plurality of circumferential cuts are generated by the circumferential cutting edge 70 in the closing piece 8. After the cutting of the closing piece 8 proceeds as described above, a plurality of arc-shaped restraining pieces 72 act on the closing piece 8 to displace the closing piece 8 upward, and thus the container neck 6 A discharge path leading to the inside of the section 74 is generated, and the content stored in the container 6, that is, the additive (not shown) is mixed into the content stored in the container. Since the closing piece 8 has a plurality of radial cuts and a plurality of circumferential cuts, the closing piece 8 can be displaced sufficiently easily by the action of the restraining piece 72 to generate the required discharge path. it can. As clearly shown in FIG. 6, when the first member 2 is lowered with respect to the second member 4 to the discharge position shown in FIG. 6, the outer periphery of the side wall 12 of the container 6 of the first member 2. An annular seal protrusion 32 formed at the lower surface is brought into close contact with the lower portion of the inner peripheral surface of the upper portion 36 of the cylindrical body 34 constituting the second member 4, and thus the space between the container 6 and the cylindrical body 34 is sealed. Is done. In addition, the lower end of the protruding piece 16 disposed on the side wall 12 of the container 6 abuts or approaches the lower end of the slit 42 formed in the upper portion 36 of the cylindrical body 34, thereby allowing the consumer to It can be visually confirmed that the member 4 has been lowered relative to the first member 2 to the discharge position shown in FIG.

収容体６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、必要に応じて容器を適宜に振って添加物を内容物に充分に混合し、しかる後に第二の部材４を図６において上方から見て反時計方向に回転せしめて第二の部材４及び第一の部材２を容器の口頸部７４から離脱せしめ、容器内の内容物を消費することができる。 After substantially all of the additive contained in the container 6 has been discharged and mixed into the contents contained in the container, the contents of the additive are shaken as necessary. Then, the second member 4 is rotated counterclockwise as viewed from above in FIG. 6 to separate the second member 4 and the first member 2 from the mouth-neck portion 74 of the container.
