Description

本発明は、蓋ディスクと、液体を運搬および貯蔵する容器の充填短管および／または排出短管を閉鎖するためのめねじを有する、蓋ディスクの外周に直角に接続された蓋外側エッジと、栓閉塞部材をねじ込むためのめねじを有する、蓋ディスクに下向きに配置された中央の栓短管とを備えた、合成樹脂製のねじ蓋に関する。   The present invention comprises a lid disk and a lid outer edge connected at right angles to the outer circumference of the lid disk, having internal threads for closing the filling and / or draining short tubes of the container carrying and storing the liquid; The present invention relates to a synthetic resin screw lid provided with a central stopper short tube disposed downward on a lid disk having a female screw for screwing a stopper closing member.

格子棒または金属薄板からなる外壁を備えたパレット容器の栓付き樽または合成樹脂製内側容器の充填短管を閉鎖するための、特許文献１によって知られている冒頭に述べた種類のねじ蓋は、特に化学的な液体を運搬および貯蔵するための容器の場合に、ねじ蓋の栓短管内で栓閉塞部材をシールするためのシールリングが、その製作材料の経時変化に基づいて次第に栓閉塞部材の閉鎖部の封止性を保証しなくなり、シールリングを定期的に交換しなければならないという欠点がある。   A screw cap of the kind mentioned at the outset known from US Pat. No. 6,056,056 for closing a barrel with a stopper of a pallet container or an inner container made of synthetic resin with an outer wall made of lattice bars or thin metal plates. In particular, in the case of a container for transporting and storing chemical liquids, a sealing ring for sealing the plug closing member within the short tube of the screw cap is gradually plugged based on the aging of the material produced. There is a disadvantage that the sealing performance of the closing portion is not guaranteed and the seal ring must be replaced periodically.

欧州特許第０６５０４４６Ｂ１号明細書European Patent No. 0650446B1 specification

本発明の根底をなす課題は、栓閉塞部材の閉鎖部の封止性が改善され、且つねじ蓋を備えた何回を使える液体容器の製作コストおよび運転コストが低減されるように、冒頭に述べた種類のねじ蓋を改良することである。 Problem underlying the present invention is an improved sealing of the closure of the bung plug, and as manufacturing and operating costs of the liquid container which can be used many times with a screw cap is reduced, at the beginning It is to improve the screw cap of the kind mentioned.

この課題は本発明に従い、請求項１、および７の特徴を有するねじ蓋によって解決される。 This object is achieved according to the invention by a screw cap having the features of claims 1 and 7 .

従属請求項は本発明の有利で合目的な発展形態を含んでいる。   The dependent claims contain advantageous and suitable developments of the invention.

栓閉塞部材の閉鎖部を有する栓短管を備えた本発明に係るねじ蓋は、次の利点を有する。   The screw cap according to the present invention including the short plug tube having the closing portion of the plug closing member has the following advantages.

ねじ蓋の栓短管を閉鎖するための合成樹脂製栓閉塞部材は、それと一体に射出成形された円錐状多重シールを備えている。この多重シールは互いに離隔された、複数のシールリングの形をしている。これらシールリングは、栓閉塞部材をねじ込む際に栓短管の円錐状内側シール面に押し付けられる。この構造により、栓閉塞部材の閉鎖部は最適な封止性を有する。内圧が加えられる容器の場合には、ねじ蓋の栓短管のための栓閉塞部材の閉鎖部の封止性が更に改善される。これは、栓閉塞部材のねじ込みによって生じる、栓短管の円錐状内側シール面に対する、閉塞部材の円錐状多重シールのこれらシールリングの押圧力が、多重シールを備えた栓閉塞部材のねじ込みスリーブの封止端部の内壁に作用する容器の内圧によって更に高まることにより達成される。定期的に交換しなければならないシールリングを省略したことにより、シールリングを有する栓閉塞部材によって閉鎖される栓短管を備えた公知のねじ蓋と比べて、製作コストを低減することができ、そして蓋の栓短管のための新しい栓閉塞部材の閉鎖部を有するねじ蓋を備えた何回も使用できる液体容器のための維持費を低減することができる。 A synthetic resin plug closing member for closing a plug short tube of a screw lid includes a conical multiple seal formed by injection molding integrally therewith. The multiple seal is in the form of a plurality of seal rings spaced apart from each other. These seal rings are pressed against the conical inner sealing surface of the short plug tube when screwing the plug closing member. With this structure, the closing portion of the plug closing member has an optimum sealing property. In the case of a container to which an internal pressure is applied, the sealing performance of the closure portion of the plug closing member for the screw cap short tube is further improved. This is because the pressing force of these sealing rings of the conical multiple seal of the closing member against the conical inner sealing surface of the short plug tube caused by the screwing of the plug closing member is such that the screwing sleeve of the plug closing member with multiple seals This is achieved by further increasing by the internal pressure of the container acting on the inner wall of the sealed end. By omitting the seal ring that must be replaced periodically, the manufacturing cost can be reduced compared to a known screw cap with a plug short tube that is closed by a plug closure member having a seal ring, And the maintenance costs for a liquid container that can be used many times with a screw cap with a closure of a new plug closure member for the short plug of the lid can be reduced.

次に、図に基づいて本発明を説明する。   Next, the present invention will be described with reference to the drawings.
