More specifically, the opening of the container is sealed by a seal member and extends upward so as to surround the seal member. The present invention relates to an opening device capable of drinking or pouring a suitable content liquid for a container in which a delivery tube is formed.
飲料や調味料などの内容液を保存する際には紙パック等の容器が一般に用いられている。そしてこの容器の上端における所定箇所には開口部が形成されており、出荷時には当該開口部はシール部材などにより封止されている。
このような容器に収容された内容液を注出するとき、注出栓など注出用の部材を用いてシール部材を破断させることが一般的に行われており、例えば下記のような技術が開示されている。
Containers such as paper packs are generally used for storing liquid contents such as beverages and seasonings. And the opening part is formed in the predetermined location in the upper end of this container, and the said opening part is sealed with the sealing member etc. at the time of shipment.
When the content liquid stored in such a container is poured out, it is generally performed to break the sealing member using a member for pouring out such as a pouring stopper. For example, the following technique is used. It is disclosed.
すなわち特許文献１には、液体容器用注出栓が開示されており、当該注出栓は破断可能なシートによって封止された液体容器の注出孔に取着する注出栓本体と、該注出栓本体を開閉自在とするキャップから構成されている。また、この注出栓本体には開封部材が備えられており、当該開封部材は開口筒壁に離間可能に連結部材を介して固定されている。
収容した液体を注出する時には開封部材を指などで押圧して連結手段を破断させ、さらにそのまま押圧を続けることによって開封部材が容器の注出孔を封止しているシートを破断して容器に収容された液体が注出可能となる。
