Description
本発明は、牛乳やジュース等の飲料液体を収容するゲーブルトップ型容器に関する。 The present invention relates to a gable top type container for containing a beverage liquid such as milk or juice.
従来、牛乳カートンに代表される飲料用の紙容器として、表裏面に熱可塑性樹脂を積層した板紙素材で構成されたゲーブルトップ型容器がある。ゲーブルトップ型容器は、飲料液体が収容される筒状胴部と、筒状胴部の上端に連設された切妻屋根とを備えている。切妻屋根は、一対の屋根パネルと、一対の切妻屋根間に内向きに折り込まれた一対の妻壁パネルと、一対の屋根パネルの上端部および一対の妻壁パネルの上端部を接合して形成されるトップシールとを備えている（例えば、特許文献１参照）。 Conventionally, as a paper container for beverages represented by a milk carton, there is a gable top type container made of a paperboard material in which a thermoplastic resin is laminated on the front and back surfaces. The gable top type container includes a tubular body for storing a beverage liquid and a gable roof connected to the upper end of the tubular body. The gable roof is formed by joining a pair of roof panels, a pair of gable wall panels folded inward between the pair of gable roofs, and the upper ends of the pair of roof panels and the upper ends of the pair of gable wall panels. It is provided with a top seal (see, for example, Patent Document 1).
このようなゲーブルトップ型容器を開封する際は、開封部側で一対の屋根パネルの間に指を差し入れつつ、これらの屋根パネルを互いに離反させて後方に折り返す（１次開封）。この状態で、左右方向からトップシールに力をかけながら妻壁パネルを前方に突出させることにより、屋根パネルから妻壁パネルを剥離させて開封する（２次開封）。 When opening such a gable top type container, while inserting a finger between the pair of roof panels on the opening side, these roof panels are separated from each other and folded back (primary opening). In this state, the end wall panel is peeled off from the roof panel and opened by projecting the end wall panel forward while applying force to the top seal from the left-right direction (secondary opening).
しかしながら、特許文献１に記載されたような従来のゲーブルトップ型容器は、妻壁パネルに上下方向に延びる補強線が設けられているため、妻壁パネルが開封時の突出方向に湾曲し易くなってしまう。このため、２次開封時にトップシールにかけた力がその接着面に伝わり難くなったり、妻壁パネルが屋根パネルから剥離する前に折れ曲がったりしてしまうことがあり、開封性が十分でないという問題がある。
また、妻壁パネルが開封時の突出方向に湾曲し易くなるため、開封後の注ぎ口がすぼまって細くなってしまい、液体が注ぎ口を通過し難くなるという問題がある。
However, in the conventional gable top type container as described in Patent Document 1, since the end wall panel is provided with a reinforcing line extending in the vertical direction, the end wall panel tends to be curved in the projecting direction at the time of opening. Will end up. For this reason, the force applied to the top seal at the time of secondary opening may be difficult to be transmitted to the adhesive surface, or the end wall panel may bend before being peeled from the roof panel, resulting in insufficient openability. is there.
Further, since the end wall panel is easily curved in the protruding direction at the time of opening, there is a problem that the spout after opening is narrowed and narrowed, and it becomes difficult for the liquid to pass through the spout.
本発明の目的は、開封性を向上できるゲーブルトップ型容器を提供することにある。
本発明の別の目的は、液体が注ぎ口を通過し難くなることを防止できるゲーブルトップ型容器を提供することにある。

The roofs are a pair of roof panels facing each other, a pair of gable wall panels facing each other in a direction intersecting the pair of roof panels in opposite directions, and being folded between the pair of roof panels, and the pair of roofs. The upper end portion of the panel and the upper end portion of the pair of gable wall panels are joined to form a top seal, and the gable wall panel has a thick portion formed thicker than the roof panel. It is characterized by.
本発明によれば、妻壁パネルが厚肉部を備えているため、妻壁パネルの剛性を高くすることができ、２次開封時に、妻壁パネルが湾曲してしまうことを防止できる。このため、２次開封時にトップシールにかけた力をその接着面に伝わり易くすることができる。また、妻壁パネルが屋根パネルから剥離する前に折れ曲がってしまうことを防止できる。従って、ゲーブルトップ型容器の開封性を向上できる。
また、開封時に妻壁パネルが湾曲してしまうことを防止できるため、開封後の注ぎ口がすぼまって細くなってしまうのを防ぐことができ、液体が注ぎ口を通過し難くなることを防止できる。

以上のゲーブルトップ型容器１は、図３に示すゲーブルトップ型容器用パネル１０から、次のような手順で形成される。
先ず、ゲーブルトップ型容器用パネル１０のシールパネル２５、３５、４５を胴部パネル２１、底部パネル３１、屋根パネル４１に加熱シールし、カートンブランクを形成する。このカートンブランクが角筒状とされた状態において、底部パネル３１、３２を谷折線３１１、３２１に沿って谷折りしながら、底部横折線３０Ｅにより底部パネル３３、３４間に内向きに折り込み、底部パネル３３、３４と重ね合わせる。そして、底部パネル３１〜３４の重ね合わせ部分全体を加熱シールし、底部３を形成する。
The above gable top type container 1 is formed from the gable top type container panel 10 shown in FIG. 3 by the following procedure.
First, the seal panels 25, 35, and 45 of the gable top type container panel 10 are heat-sealed to the body panel 21, the bottom panel 31, and the roof panel 41 to form a carton blank. In a state where the carton blank has a square tubular shape, the bottom panels 31 and 32 are valley-folded along the valley fold lines 311, 321 and folded inward between the bottom panels 33 and 34 by the bottom horizontal fold line 30E to form the bottom. Overlay with panels 33 and 34. Then, the entire overlapped portion of the bottom panels 31 to 34 is heat-sealed to form the bottom portion 3.
次いで、谷折線４３２、４４２で第２折込部４３４、４４４を折り返しながら、上部横折線４３Ａ、４４Ａで第１折込部４３３、４４３を内向きに折り込んで、屋根パネル４１、４２の間に妻壁パネル４３、４４を折り込む。この際、屋根パネル４１、４２は、妻壁パネル４３、４４の折り込みに連動して、上部横折線４１Ａ、４２Ａにより内向きに折り曲げられる。そして、屋根パネル４１、４２を谷折線４１１、４２１に沿って谷折りするとともに、妻壁パネル４３、４４を山折線４３１、４４１に沿って山折りし、折返線４３７、４４７で折り返された妻壁パネル４３、４４の上端部４３５、４４５を屋根パネル４１、４２の上端部４１３、４２３間に介在させる。そして、上端部４１３、４２３、４３５、４４５を互いに加熱シールし、トップシール４６を形成する。 Next, while folding back the second folding portions 434 and 444 at the valley folding lines 432 and 442, the first folding portions 433 and 443 are folded inward at the upper horizontal folding lines 43A and 44A, and the wife wall between the roof panels 41 and 42. Fold the panels 43 and 44. At this time, the roof panels 41 and 42 are bent inward by the upper horizontal folding lines 41A and 42A in conjunction with the folding of the end wall panels 43 and 44. Then, the roof panels 41 and 42 are valley-folded along the valley fold lines 411 and 421, the wife wall panels 43 and 44 are mountain-folded along the mountain fold lines 431 and 441, and the wife is folded back along the turn-back lines 437 and 447. The upper end portions 435 and 445 of the wall panels 43 and 44 are interposed between the upper end portions 413 and 423 of the roof panels 41 and 42. Then, the upper end portions 413, 423, 435, and 445 are heat-sealed with each other to form the top seal 46.
一方、ゲーブルトップ型容器１を開封する際は、妻壁パネル４３側で一対の屋根パネル４１、４２の間に指を差し入れつつ、図２に示すように、屋根パネル４１、４２を互いに離反させ、屋根パネル４１、４２および妻壁パネル４３を後方に折り返す（１次開封）。この状態で、左右方向からトップシール４６に力をかけながら妻壁パネル４３を前方に突出させることにより、屋根パネル４１、４２から妻壁パネル４３を剥離させて開封する（２次開封）。これにより、妻壁パネル４３で注ぎ口が形成され、当該注ぎ口で内部の飲料液体を注ぐことが可能となる。 On the other hand, when opening the gable top type container 1, the roof panels 41 and 42 are separated from each other as shown in FIG. 2 while inserting a finger between the pair of roof panels 41 and 42 on the end wall panel 43 side. , Roof panels 41, 42 and end wall panel 43 are folded back (primary opening). In this state, by projecting the end wall panel 43 forward while applying force to the top seal 46 from the left-right direction, the end wall panel 43 is peeled off from the roof panels 41 and 42 and opened (secondary opening). As a result, a spout is formed by the end wall panel 43, and the beverage liquid inside can be poured through the spout.
以上のような実施形態によれば、妻壁パネル４３が厚肉部４３６を備えているため、妻壁パネル４３の剛性を高くすることができ、２次開封時に、妻壁パネル４３が湾曲してしまうことを防止できる。このため、２次開封時にトップシール４６にかけた力をその接着面に伝わり易くすることができる。また、妻壁パネル４３が屋根パネル４１、４２から剥離する前に折れ曲がってしまうことを防止できる。従って、ゲーブルトップ型容器１の開封性を向上できる。
また、２次開封時に妻壁パネル４３が湾曲してしまうことを防止できるため、開封後の注ぎ口がすぼまって細くなってしまうのを防ぐことができ、液体が注ぎ口を通過し難くなることを防止できる。
According to the above embodiment, since the end wall panel 43 includes the thick portion 436, the rigidity of the end wall panel 43 can be increased, and the end wall panel 43 is curved at the time of secondary opening. It can be prevented from being lost. Therefore, the force applied to the top seal 46 at the time of secondary opening can be easily transmitted to the adhesive surface. Further, it is possible to prevent the end wall panel 43 from being bent before being peeled from the roof panels 41 and 42. Therefore, the openability of the gable top type container 1 can be improved.
Further, since it is possible to prevent the end wall panel 43 from being curved at the time of secondary opening, it is possible to prevent the spout after opening from being squeezed and thinned, and it is difficult for the liquid to pass through the spout. It can be prevented from becoming.
また、厚肉部４３６が妻壁パネル４３のトップシール４６側の領域に設けられているため、妻壁パネル４３のトップシール４６側の剛性を高くすることができ、２次開封時に妻壁パネル４３が折れ曲がってしまわずに、トップシール４６に左右方向からかかる力を効率良く接着部に伝えることができる。
