Description

本発明は、焼菓子、スナック菓子、チョコレート菓子、アイス、キャンデー等の食品等を収容する包装容器の振出口付蓋材に関する。 The present invention relates to a lid with a swing outlet for a packaging container for storing food such as baked confectionery, snack confectionery, chocolate confectionery, ice and candy.

従来より、焼菓子、スナック菓子、チョコレート菓子、アイス、キャンデー等の食品を紙カップや合成樹脂製のフランジ部を有する有底状容器等に開口部より収容して開口部を蓋材で被覆しフランジ部で熱接着して密封したカップ型の包装容器が、店頭で立てた状態で陳列できるために、消費者への訴求効果が大きなものとなり、販売者にとっては好ましい形態であり、一方、これを購入する消費者にとってはそのまま立てた状態で食することができ、利便性に優れた形態であり広く使用されている。これらの形態は蓋材をフランジ部より剥離して容易に開封でき、内容物を食することができる。また、小出しにしながら食する内容物、例えばチョコチップのような場合には振出口付オーバーキャップが嵌合されており、振出口付オーバーキャップを外して蓋材を剥離して開封後、再び振出口付オーバーキャップを有底状容器の開口部に嵌合して小出しにできる形態が採用されている。さらには内面が熱可塑性合成樹脂層とされている容器本体の開口部に板紙と熱可塑性合成樹脂のフィルムの積層材の蓋片が溶着されている容器において、内側面にポリエチレンフィルムが積層されている蓋片に外面からフィルムとの積層面に達する外ハーフカット線を開曲線形状で切り込み、蓋面のフィルム面から板紙との積層面に達し、外ハーフカット線の開曲線形状に沿い、僅かに大型で相似形の内ハーフカット線を切り込み、蓋片に開口部をあけうる容器（例えば、特許文献１参照）等の小出しにできるようにした形態が用いられている。 Conventionally, foods such as baked confectionery, snack confectionery, chocolate confectionery, ice cream, candy, etc. are received from the opening in a paper cup or a bottomed container having a synthetic resin flange, and the opening is covered with a lid. The cup-type packaging container that is heat-bonded and sealed in the above can be displayed in a standing state at the storefront, which has a great appeal to consumers and is a favorable form for the seller, while purchasing this It can be eaten in a standing state for consumers, and it is a convenient form and widely used. In these forms, the lid member can be peeled off from the flange portion and easily opened, and the contents can be eaten. In addition, in the case of contents to be eaten while dispensing, such as a chocolate chip, an overcap with a shaker outlet is fitted, and after removing the lid by opening the overcap with a shaker outlet and opening it, shake again. The form which fits the overcap with an exit to the opening part of a bottomed container and can be dispensed is employ | adopted. Furthermore, in a container in which a cover piece of a laminate of a paperboard and a thermoplastic synthetic resin film is welded to the opening of the container body whose inner surface is a thermoplastic synthetic resin layer, a polyethylene film is laminated on the inner surface Cut the outer half-cut line from the outer surface to the laminated surface with the film into the cover piece with an open curve shape, reach the laminated surface with the paperboard from the film surface of the lid surface, and slightly along the open curve shape of the outer half-cut line A large-sized and similar inner half-cut line is cut into a small container such as a container that can open an opening in the lid piece (see, for example, Patent Document 1).

前者の振出口付オーバーキャップを採用する形態は、まず、振出口付オーバーキャップを容器から外し、次に蓋材を一部若しくは全部を剥離して開封し、再び、振出口付オーバーキャップを開口部に被せて嵌合してから振出口より内容物を取り出すものであり、振出口付オーバーキャップを外したり被せたりする必要があり、面倒なものである。また、後者の特許文献１の発明は、Ｕ字のごとき開曲線形状に切り込まれた外ハーフカット線で囲まれた部分を指頭で容器内方に向かって押圧すると、外ハーフカット線で囲まれた部分と、外ハーフカット線に沿い、該ハーフカット線の開曲線形状より僅かに大形の相似形に切り込まれた内ハーフカット線で囲まれた部分とが一体となって、各ハーフカット線部分で切り離され、該切り離し小片が一体に内方へフランジで折曲されて開口部が形成される。しかしながら、切り離し小片がフランジで折曲されているために、焼菓子、スナック菓子、チョコレート菓子、キャンデー等の棒状、球状、角状等の固形の食品用に用いると内容物を取り出すときに切り離し小片に内容物が引っ掛かって取り出しにくいという問題がある。また、輸送時や商品の取扱い時に、落下衝撃が加わると、特に各ハーフカットで囲まれた部分が最初に接地する方向に落下衝撃が負荷されると各ハーフカットで囲まれた部分にクラックが入ることがあるという問題がある。
実開平６−３８２６号公報 In the form of using the former overcap with an outlet, first remove the overcap with an outlet from the container, then peel off part or all of the lid material, and then open the overcap with an outlet again. The contents are taken out from the outlet after being fitted over the part, and it is necessary to remove or cover the overcap with the outlet, which is troublesome. Moreover, the latter invention of Patent Document 1 is surrounded by an outer half-cut line when a portion surrounded by an outer half-cut line cut into an open curve shape such as a U-shape is pressed toward the inside of the container with a fingertip. And the part surrounded by the inner half-cut line cut into a similar shape slightly larger than the open curve shape of the half-cut line along the outer half-cut line, It is cut off at the half-cut line portion, and the cut piece is bent inward with a flange to form an opening. However, since the cut-off piece is bent at the flange, when used for solid food such as baked confectionery, snack confectionery, chocolate confectionery, candy, etc. There is a problem that the contents are caught and difficult to take out. Also, if a drop impact is applied during transportation or handling of the product, a crack will occur in the portion surrounded by each half cut, particularly if the portion surrounded by each half cut is loaded in the direction of grounding first. There is a problem that it may enter.

本発明にかかる振出口付蓋材の一実施形態は図１、図２に示す通りである。図１は本発明にかかる振出口付蓋材の一実施形態を示す平面図であり、図２は図１におけるＸ−Ｘ線断面図であって積層材の構成を示すものである。図１に示すように本発明の振出口付蓋材１の一実施形態は、円形状であって周縁に外方に突出する摘み部Ｔが形成され、図２に示すように基材層２１、アルミ箔層２２、熱接着性樹脂層２３が順次積層された積層材２から構成され、上部の開口部の周縁にフランジ部を備えた有底状容器のフランジ部と熱接着性樹脂層２３とで熱接着される周縁熱接着部３を有し、該周縁熱接着部３の近傍に基材層２１の外面からアルミ箔層２２の直近位置または該層に達するハーフカット線５（図２では第二ハーフカット線５４が見えている。）が切り込まれ形成された振出口部４を備えている。このようにハーフカット線５を形成することによりハーフカット線５に沿って振出口部４の開封が容易であると共にアルミ箔層２２によって振出口付蓋材１のガスバリア性が確保され、内容物の品質劣化が防止できるものである。なお、摘み部Ｔは設けなくてもよいが、例えばキャンペーン等で振出口付蓋材の裏面（熱接着性樹脂層２３側）に記載領域を設ける場合、内容物を消費後、振出口付蓋材を剥離する必要があり、摘み部Ｔを設けるのが好ましい。なお、一実施形態では摘み部Ｔを設ける位置を振出口部４と対向する位置としたが、これに限定されるものではない。 One embodiment of a lid with a swing outlet according to the present invention is as shown in FIGS. FIG. 1 is a plan view showing an embodiment of a lid member with a swing outlet according to the present invention, and FIG. 2 is a cross-sectional view taken along the line XX in FIG. As shown in FIG. 1, in the embodiment of the lid member 1 with a swing outlet according to the present invention, a knob portion T that is circular and protrudes outward is formed on the periphery, and the base material layer 21 is formed as shown in FIG. 2. , An aluminum foil layer 22 and a heat-adhesive resin layer 23 are sequentially laminated, and the flange portion of the bottomed container and the heat-adhesive resin layer 23 provided with a flange portion at the periphery of the upper opening. And a half-cut line 5 (see FIG. 2) that reaches the position near the edge of the aluminum foil layer 22 from the outer surface of the base material layer 21 in the vicinity of the edge heat-bonding part 3. Then, the second half-cut line 54 is visible). By forming the half-cut line 5 in this manner, the outlet 4 can be easily opened along the half-cut line 5, and the gas barrier property of the outlet cover 1 is secured by the aluminum foil layer 22. Quality deterioration can be prevented. In addition, although the knob | pick part T does not need to be provided, when providing the description area | region on the back surface (thermal-adhesive resin layer 23 side) of a cover material with a shaker outlet, for example in a campaign etc., after consuming contents, a cover with a shaker outlet It is necessary to peel off the material, and it is preferable to provide a knob T. In addition, in one Embodiment, although the position which provides the knob | pick part T was made into the position facing the swing-out part 4, it is not limited to this.

さらに振出口部４は、振出口付蓋材１の中心側Ｃに始点５１と終点５２とを有し、始点５１から周縁熱接着部３の近傍に向かって延びる第一ハーフカット線５３と該第一ハーフカット線５３の端部近傍に位置し周縁熱接着部３に沿って延びるミシン目状の第二ハーフカット線５４と該第二ハーフカット線５４の端部近傍に位置し終点５２に戻る第三ハーフカット線５５が形成され、第一ハーフカット線５３と第二ハーフカット線５４との間及び第二ハーフカット線５４と第三ハーフカット線５５との間に間欠した曲線状の切目からなる連結部ハーフカット線５６が基材層２１の外面から形成され、第一ハーフカット線５３、第二ハーフカット線５４、第三ハーフカット線５５、及び連結部ハーフカット線５６で囲まれた振出口片６が設けられ構成されている。また、第一ハーフカット線５３と第三ハーフカット線５５はそれぞれ始点５１と終点５２からお互いに拡開するように周縁熱接着部３の近傍まで延び振出口部４は略花びら状に設けられている。なお、第二ハーフカット線５４はミシン目とするほうが、振出口付蓋材１を用いた包装容器が、万一、第二ハーフカット線側が先に接地するように落下した場合にも第二ハーフカット線５４にクラックが入りにくくすることができ好ましい。 Further, the outlet portion 4 has a start point 51 and an end point 52 on the center side C of the outlet cover 1, and a first half-cut line 53 extending from the start point 51 toward the vicinity of the peripheral heat bonding portion 3 A perforated second half-cut line 54 extending in the vicinity of the end of the first half-cut line 53 and extending along the peripheral heat-bonding part 3, and positioned in the vicinity of the end of the second half-cut line 54 at the end 52 The returning third half-cut line 55 is formed, and has a curved shape intermittent between the first half-cut line 53 and the second half-cut line 54 and between the second half-cut line 54 and the third half-cut line 55. A connecting portion half-cut line 56 made of a cut is formed from the outer surface of the base material layer 21, and is surrounded by the first half-cut line 53, the second half-cut line 54, the third half-cut line 55, and the connecting portion half-cut line 56. Provided with an outlet piece 6 It has been made. The first half-cut line 53 and the third half-cut line 55 extend from the start point 51 and the end point 52 to the vicinity of the peripheral heat-bonding part 3 so as to expand from each other, and the swing-out part 4 is provided in a substantially petal shape. ing. It should be noted that the second half-cut line 54 is perforated even if the packaging container using the lid member 1 with a shaker is dropped so that the second half-cut line side is grounded first. The half cut line 54 can be made difficult to crack, which is preferable.

連結部ハーフカット線５６は間欠した略Ｕ字状の切目５７からなり、該Ｕ字状の切目５７は振出口付蓋材１の平面視中心を通り摘み部Ｔと振出口部４を結ぶ方向軸（以下Ｘ軸と略称する）に対して平行とならないように傾斜若しくは直交させて２ケ形成され、且つ、互いに相反する方向に配設されている。このような構成にすることにより、振出口付蓋材を用いた包装容器がＸ軸方向に且つ振出口部４が最初に接地するように落下して連結部ハーフカット線５６に落下衝撃が負荷されてもＵ字状の切目５７によりクラックが入ることが防止でき、積層材２のアルミ箔層２２に破れやピンホールやクラックが発生することがなく内容物の品質が確保できるものである。これはＸ軸方向に衝撃が負荷された時にＸ軸と直交する方向に容器を押し広げようとする力が加わり連結部ハーフカット線５６にＸ軸と平行な直線部が存在すると連結部ハーフカット線５６にクラックが発生しやすいが、Ｕ字状の切目５７とすることにより、Ｘ軸方向に平行な部分が極小化されクラック発生防止できると考えられる。したがって、連結部ハーフカット線５６は間欠した曲線状であれば、特にＵ字状に限定されるものでなく、Ｃ字状、Ｓ字状でもよい。また、間欠した曲線状の切目の数は１ケ以上であればよく、設ける振出口部４の大きさ、形状により任意に設けることができる。 The connecting portion half-cut line 56 includes intermittent U-shaped cuts 57, and the U-shaped cuts 57 pass through the center in plan view of the lid member 1 with a shaker and connect the knob part T and the shaker part 4. Two pieces are formed so as to be inclined or orthogonal to each other so as not to be parallel to an axis (hereinafter abbreviated as X axis), and are arranged in directions opposite to each other. With such a configuration, the packaging container using the lid member with the shaker is dropped in the X-axis direction and the shaker part 4 is first grounded, and a drop impact is applied to the connecting part half-cut wire 56. However, the U-shaped cut 57 can prevent cracks from occurring, and the aluminum foil layer 22 of the laminate 2 can be prevented from being broken, pinholes or cracks, and the quality of the contents can be ensured. This is because when a force is applied to push the container in a direction perpendicular to the X-axis when an impact is applied in the X-axis direction, and there is a straight portion parallel to the X-axis in the connecting portion half-cut line 56, the connecting portion half-cut Although cracks are likely to occur in the line 56, it is considered that the U-shaped cut 57 minimizes the portion parallel to the X-axis direction and can prevent cracking. Accordingly, the connecting portion half-cut line 56 is not particularly limited to a U shape as long as it is an intermittent curved shape, and may be a C shape or an S shape. Moreover, the number of intermittent curved cuts should just be one or more, and can be arbitrarily provided according to the magnitude | size and shape of the shaker outlet part 4 to provide.

第一ハーフカット線５３及び第三ハーフカット線５５は、間欠した切目５８からなり、該間欠した切目５８は第一ハーフカット線５３及び第三ハーフカット線５５に沿った方向の直線切目５８ａと、該直線切目５８ａの振出口付蓋材１の中心側Ｃから遠い方の端より振出口片６から外方に向かい直線切目５８ａに対して鈍角で斜めに延びる斜線切目５８ｂとから構成されている。この構成にすることにより振出口部を外面から有底状容器側に向かって押すことにより、開封でき、内容物を簡単に小出しにできる振出口が形成できると共に包装容器の輸送や取扱い時に落下衝撃が加わってもハーフカット線５にクラックの入りにくいものとできる。第一ハーフカット線５３及び第三ハーフカット線５５は連続した線でもよいが、間欠した切目のほうが耐落下衝撃性が優れるので好ましい。また、間欠した切目の形状は特に限定されるものではなく、直線、曲線あるいはこれらを組合わせたものでもよい。 The first half-cut line 53 and the third half-cut line 55 include intermittent cuts 58, and the intermittent cuts 58 are linear cuts 58 a in the direction along the first half-cut line 53 and the third half-cut line 55. The diagonal cut 58b extends obliquely at an obtuse angle with respect to the straight cut 58a from the end of the straight cut 58a that is farther from the center side C of the lid member 1 with the shake outlet toward the outside from the swing piece 6. Yes. By adopting this structure, the outlet can be opened by pushing the outlet part from the outer surface toward the bottomed container, and the outlet can be formed so that the contents can be easily dispensed. Even if it is added, it is possible to make the half-cut wire 5 difficult to crack. The first half-cut line 53 and the third half-cut line 55 may be continuous lines, but intermittent cuts are preferable because they have excellent drop impact resistance. Moreover, the shape of the intermittent cut is not particularly limited, and may be a straight line, a curved line, or a combination thereof.

さらに、ハーフカット線５を構成する第一ハーフカット線５３の始点５１側の先端部分が振出口付蓋材１の中心側Ｃに突き出し、第一ハーフカット線５３に対して第三ハーフカット線５５の反対側に始点５１が位置するようにＵ字状に形成され、第三ハーフカット線５５の終点５２側の先端部分が振出口付蓋材１の中心側Ｃに突き出し、第三ハーフカット線５５に対して第一ハーフカット線５３の反対側に終点５２が位置するようにＵ字状に形成されている。このような構成にすることによって、振出口付蓋材１の振出口部４を押し破り開封してもハーフカット線５に沿って引裂かれた積層材２の引裂き伝播が第一ハーフカット線５３、第三ハーフカット線５５の始点５１及び終点５２で停止し、振出口付蓋材の引裂き伝播のストッパーの役目を果たす。 Furthermore, the tip portion on the start point 51 side of the first half-cut line 53 constituting the half-cut line 5 protrudes to the center side C of the lid member 1 with a swing outlet, and the third half-cut line with respect to the first half-cut line 53. It is formed in a U shape so that the start point 51 is located on the opposite side of 55, the tip end portion on the end point 52 side of the third half-cut line 55 protrudes to the center side C of the lid member 1 with a swing outlet, and the third half-cut It is formed in a U shape so that the end point 52 is positioned on the opposite side of the first half-cut line 53 with respect to the line 55. By adopting such a configuration, the tear propagation of the laminated material 2 that is torn along the half-cut line 5 even if the swing-out part 4 of the lid member 1 with the shake-out opening is pushed open and opened is the first half-cut line 53. It stops at the start point 51 and the end point 52 of the third half-cut line 55, and serves as a stopper for tear propagation of the lid member with a swing outlet.
