Description

本発明は、カップ入り焼きそば等のように、麺に熱湯を注いで一定時間放置した後、湯切りを行う容器に使用する湯切り孔付き蓋材に関する。   The present invention relates to a lid material with a hot water cut hole used for a container for hot water cutting after pouring hot water into noodles and leaving it for a certain period of time, such as a cupped fried noodle.

従来、カップ入り焼きそばは、発泡ポリスチレン等からなる容器に焼きそばを収納し、湯切り孔となる切込が形成されたプラスチック成形蓋が被せられ、全体を収縮フィルムにて収縮包装した包装形態のもの、ないしは発泡ポリスチレン等からなる容器に焼きそばを収納し、箸等により突き刺すことにより湯切り孔を形成できるようにした紙とアルミニウム箔の積層体からなる蓋材を容器に熱接着して取り付け、全体を収縮フィルムにて収縮包装した包装形態のもの等が知られている。しかしながら、上記前者の包装形態の容器を使用した場合には、プラスチック成形蓋に湯切り孔となる切込が形成されているのでガスバリヤー性がない上に完全密封されていないために、保管中に内容物の匂いが外部に漏れ出すという欠点があった。また、後者の包装形態の容器を使用した場合には、湯切りする際に蓋材の所定箇所を箸等で突き刺して孔を開ける必要があり、孔を開けるのが煩雑である上に熱湯が入った容器の上から蓋材を突き刺す際に火傷をするおそれがある等の欠点があった。   Traditionally, fried noodles with cups are packaged in such a way that fried noodles are stored in a container made of expanded polystyrene, etc., covered with a plastic molding lid with cuts to form hot water cutting holes, and the whole is shrink-wrapped with a shrink film. Or the fried noodles are stored in a container made of expanded polystyrene, etc., and a lid made of a laminate of paper and aluminum foil that can be formed with a chopstick or the like by sticking it with heat is attached to the container by thermal bonding. There is known a packaging form that is shrink-wrapped with a shrink film. However, when the former packaging type container is used, the plastic molding lid is formed with a notch that becomes a hot water cutting hole, so there is no gas barrier property and it is not completely sealed. The scent of the contents leaked to the outside. In addition, when the latter packaging type container is used, it is necessary to pierce a predetermined portion of the lid material with chopsticks or the like when severing hot water, and it is complicated to open the hole, and hot water is used. There were drawbacks such as burns when the lid was pierced from above the container.

上記の欠点を改良した蓋材として、特開２０００−１０９１４１号公報に記載されているような、開封用つまみと排湯口開口用のつまみを有し、基材とこれを被覆する表面シートが接着剤層を介して積層され、基材と表面シートとの層間に離型材の塗布された剥離領域と、該剥離領域内に配置された非剥離領域と、剥離領域に隣接して配置された他の非剥離領域とに区画され、前記剥離領域内にある非剥離領域内には排湯口開口部形成用ハーフカットが、内面側となる基材から接着剤層に至る範囲で形成され、剥離領域と隣接する非剥離領域とに境界線に沿って直線的に表面シートに剥離用ハーフカットが形成された構成からなり、排湯口開口用のつまみを掴んで表面シートを基材面から剥離して排湯口開口部形成用ハーフカットにて切り取ることにより排湯口開口を形成できるようにした蓋材が記載されている。しかしながら、この構成の蓋材においては、剥離領域内にある非剥離領域内に排湯口開口部形成用ハーフカットを形成する構成であるため、剥離領域内に非剥離領域を形成して、その非剥離領域内に排湯口開口部形成用ハーフカットを形成するため、非剥離領域の形成及び非剥離領域と排湯口開口部形成用ハーフカットとの見当合わせを正確に行う必要があり製造工程が煩雑になるという欠点がある。   As a cover material that has improved the above disadvantages, it has a knob for opening and a knob for opening a hot water outlet, as described in JP-A-2000-109141, and the base sheet and the surface sheet covering it are bonded. Peeling area that is laminated through the agent layer and the release material is applied between the base material and the surface sheet, the non-peeling area arranged in the peeling area, and the others arranged adjacent to the peeling area The non-peeling region is divided into a non-peeling region, and a half cut for forming a drain opening is formed in a range from the base material on the inner surface side to the adhesive layer in the non-peeling region. And a non-peeling area adjacent to each other, and a half-cut for peeling is formed on the surface sheet linearly along the boundary line. Cut with a half cut for forming the drain opening Lid which is adapted to form a discharge sprue opening is described by. However, since the lid member having this configuration is configured to form a half cut for forming the drain opening in the non-peeling region in the peeling region, the non-peeling region is formed in the peeling region. Since the half cut for forming the drain opening is formed in the peeling area, it is necessary to accurately form the non-peeling area and register the non-peeling area and the half cut for forming the drain opening. There is a drawback of becoming.

本発明の目的は、簡単に湯切り孔を形成することができ且つ製造方法が簡単な密封性に優れた湯切り孔付き蓋材を提供することである。   An object of the present invention is to provide a lid member with a hot water hole that can easily form a hot water hole and has a simple manufacturing method and excellent sealing performance.
