Description
【０００１】
【発明の属する技術分野】
本発明は、容器（トレー）にシールする紙製蓋の構造に関するものであり、さらに詳細には、開封し易くした紙製蓋に関する。
【０００２】
【従来の技術】
近年、資源枯渇問題や廃棄物の増加に係わる環境問題即ち焼却処理による様々な環境問題が取り沙汰される中で、プラスチック製の容器に代わり紙製の容器が多くの分野で使用されるようになってきた。
【０００３】
上記紙製の容器の一事例として、平坦なフランジ部を有する四角状紙容器（トレー）があり、内容物を衛生上あるいは蒸発等から保護するためそのフランジ部に紙製（厚紙製）の蓋をシールしたものがある。
【０００４】
【発明が解決しようとする課題】
しかしながら、上記の紙製の蓋をシール部から剥がし開封しようとすると、シール強度が強すぎる場合剥がれ難く、厚紙の裏面で紙ムケが発生し外観上好ましくないものであった。また、シール強度が弱すぎると意に反して剥がれてしまうなどの問題があった。
【０００５】
本発明は、かかる従来技術の問題点を解決するものであり、その課題とするところは、紙製蓋付四角状容器（トレー）の開封に際し、紙製蓋の紙ムケ等がなく、容易に確実に開封可能な紙製蓋を提供することにある。
【０００６】
【課題を解決するための手段】
本発明に於いて上記課題を達成するために、まず請求項１の発明では、四角状容器のフランジ部に、該フランジ部と略同形のシール部をシールする紙製蓋であって、その一コーナーに２本の切り込み線による把手片を設け、該切り込み線の先端より中心に向かって把手片用裏半切れ線を施し、該把手片用裏半切れ線の中心側先端より外側に前記シール部内縁に沿って周縁裏半切れ線を施し、さらに該周縁裏半切れ線の外側に一定の幅を有する周縁表半切れ線を施してなり、前記切り込み線の１／２以下で中心側に短い予備裏半切れ線を設け、該短い予備裏半切れ線の中心まで前記把手片用裏半切れ線を延長して設けてなることを特徴とする紙製蓋としたものである。
【０００７】
また、請求項２の発明では、前記切り込み線の１／２以下で中心側に垂直に短い予備裏半切れ線を設け、該予備裏半切れ線の中心まで前記把手片用裏半切れ線を延長して設けてなることを特徴とする請求項１記載の紙製蓋としたものである。
【０００８】
また、請求項３の発明では、前記把手片用裏半切れ線の外側に、かつ平行に、前記周縁表半切れ線まで予備表半切れ線を施してなることを特徴とする請求項１または２記載の紙製蓋としたものである。
【０００９】
また、請求項４の発明では、前記２本の切り込み線のいずれか一方を、中心方向に周縁表半切れ線近傍まで延長して設けてなることを特徴とする請求項１、２または３記載の紙製蓋としたものである。
【００１０】
【発明の実施の形態】
以下本発明の実施の形態を図面を用いながら詳しく説明する。
本発明の紙製蓋は、図２の側断面図に示すように、四角状紙製容器（８）のフランジ部（８２）に、該フランジ部（８２）と略同形のシール部（３０）をシールする紙製蓋（１０）であって、図２のブランク平面図に示すように、一コーナーに２本の切り込み線（２２）を施して把手片（２０）を設け、この２本の切り込み線（２２）の先端より中心に向かって把手片用裏半切れ線（２４）を施し、該２本の把手片用裏半切れ線（２４）の先端よりお互いが外側に別れるように前記シール部（３０）の内縁に沿って周縁裏半切れ線（３２）を全周にわたって施し、さらに該周縁裏半切れ線（３２）の外側に一定の幅（Ｗ）を有する周縁表半切れ線（３４）を施してなるものである。
【００１１】
上記事例では四角状容器を四角状紙製容器（８）としたが、四角状プラスチック製容器とすることもできる。しかし、従来の技術の項で述べたように、資源問題や廃棄物に係わる環境問題を考慮すれば紙製が好ましい。
【００１２】
上記本発明の紙製蓋（１０）の開封は、把手片（２０）を手で摘まんで上に引き上げて、切り込み線（２２）に従いフランジ部（８２）から剥がし、さらに引っ張り上げると把手片用裏半切れ線（２４）に従い蓋表面が周縁表半切れ線（３４）まで破れ、さらに引き上げると、図３の側断面図様の概略図に示すように、周縁表半切れ線（３４）と把手片用裏半切れ線（２４）の幅（Ｗ）で厚紙の層間剥離を起こして、紙製蓋（１０）が、シール部（３０）を有する部分と分離して完了するもので、紙製蓋のシール部に紙ムケ等がなく、外観上きれいに、確実に開封可能な紙製蓋を提供することができる。特に把手片（２０）が２本の切り込み線（２２）でなるので、開封のスタート性を良くし、容易に開封可能にすることができる。
【００１３】
また、把手片（２０）の延長上に把手片用裏半切れ線（２４）を設けたので、上記のように把手片（２０）を引き上げると把手片用裏半切れ線（２４）に従い蓋表面が破れ、一見して開封した破れ跡が残るので、この紙製蓋（１０）のバージン性（不正開封防止性）を持たせたものとすることができる。
【００１４】
上記紙製蓋（１０）は、米坪量２００ｇ／ｍ2 〜５００ｇ／ｍ2 の板紙で、表面に印刷する必要があるので少なくとも片面が白いコートマニラ、コートボール、アイボリーなどを用いることができる。さらに、四角状紙製容器（８）のフランジ部（８２）にヒートシール等でシールする必要があるので、裏面に１５μｍ〜８０μｍの薄いポリエチレンフィルムあるいはポリプロピレンフィルムなどのシール適性に優れたフィルムをラミネートしたものが使用される。これらフィルムは、内容物が食品の場合の衛生性をも考慮するもので、かつ防湿の役目もするものである。
【００１５】
また、上記周縁裏半切れ線（３２）と周縁表半切れ線（３４）の間の一定の幅（Ｗ）は、紙製蓋（１０）のサイズによっても異なるが、２乃至３ｍｍ程度が適性な値であり、これより大きすぎると上記板紙の層間剥離がスムースにいかず、小さすぎると、周縁裏半切れ線（３２）と周縁表半切れ線（３４）を蓋の表裏から別々の刃形で設ける製造工程でその位置（見当）が合わず、両者が重ね合う危惧があり、重ね合うと全切れとなり開封前に開いている状態となるので好ましくない。但し、表裏半切れ線を同時に入れる工程が可能な場合、２ｍｍ以下１ｍｍ程度まで可能である。
【００１６】
上記のような位置（見当）精度の問題では、把手片（２０）の形成する切り込み線（２２）も同様で、この切り込み線（２２）とそれに続く把手片用裏半切れ線（２４）が縦横にずれて、直線として繋がらない場合がある。このように直線的に繋がらないと、切り込み線（２２）からずれて破れることになり、確実な開封が出来なくなる。このような問題を解決するものとして、請求項２の発明は、図４の把手片（２０）近傍の拡大平面図に示すように、この切り込み線（２２）の１／２以下で蓋の中心側に垂直に短い予備裏半切れ線（２６）を設け、該短い予備裏半切れ線（２６）の中心まで前記把手片用裏半切れ線（２４）を延長して設けてなるものである。
【００１７】
上記のように、短い予備裏半切れ線（２６）と把手片用裏半切れ線（２４）の延長線を付加することによって、例え切り込み線（２２）と把手片用裏半切れ線（２４）に位置ずれが生じたとしても、紙製蓋（１０）の開封に際し、短い予備裏半切れ線（２６）と把手片用裏半切れ線（２４）の延長線から切れて、開封を確実にすることができる。
【００１８】
上記で短い予備裏半切れ線（２６）の位置を切り込み線（２２）の１／２以下としたのは、１／２を越えて把手片（２０）の先端近くに設けると、意に反してすなわち運搬中などで開封しようとする以前に、この短い予備裏半切れ線（２６）から破れてくる危惧があるためである。
【００１９】
さらにまた、開封をより確実にするものとして、請求項３の発明では、図５の把手片（２０）近傍の拡大平面図に示すように、上記２本の把手片用裏半切れ線（２４）の外側に、かつ平行に、周縁表半切れ線（３４）まで予備表半切れ線（３６）を施してなるものとしたものである。
【００２０】
上記のように予備表半切れ線（３６）を付加して施すことによって、紙製蓋（１０）の開封に際し、例え把手片用裏半切れ線（２４）から外れて破れても、破れがこの予備表半切れ線（３６）で矯正され、周縁表半切れ線（３４）に連結されて切れるので、開封をより確実にすることができる。
【００２１】
また、請求項４の発明は、図５の把手片（２０）近傍の拡大平面図に示すように、２本の切り込み線（２２）のいずれか一方（図５の事例では把手片（２０）方向から見て左側の切り込み線（２２））を、中心方向に周縁表半切れ線（３４）近傍まで延長して設けてなるものである。
【００２２】
図５に示すように、把手片（２０）の方向から見て左側の切り込み線（２２）を延長したものとすることによって、右利きの人が紙製蓋（１０）の開封に際し、右手親指と人差し指で把手片（２０）を摘んで引き上げ、さらに外側に開くように引き上げるようになり、破れあるいは切れが素早く周縁表半切れ線（３４）に連結させることができるので、より容易に確実に開封を可能にすることができる。
【００２３】
逆に把手片（２０）の方向から見て右側の切り込み線（２２）を延長したものとすると、左利きの人にとってより容易に開封可能な紙製蓋（１０）とすることもできる。
【００２４】
本発明の紙製蓋（１０）は、四角状紙製もしくはプラスチック製容器（８）の平坦なフランジ部（８２）にシールされるものであるが、容器が丸型、三角状あるいは５角形状でもフランジ部（８２）が平坦であれば使用は可能である。
【００２５】
【発明の効果】
本発明は以上の構成であるから、下記に示す如き効果がある。
即ち、四角状容器（トレー）のフランジ部に、該フランジ部と略同形のシール部をシールする紙製蓋において、その一コーナーに２本の切り込み線による把手片を設け、該切り込み線の先端より中心に向かって把手片用裏半切れ線を施し、該把手片用裏半切れ線の中心側先端より外側に前記シール部内縁に沿って周縁裏半切れ線を施し、さらに該周縁裏半切れ線の外側に一定の幅（２〜３ｍｍ程度）を有する周縁表半切れ線を施すことによって、紙製蓋のシール部に紙ムケ等がなく、外観上きれいに、確実に開封可能な紙製蓋とすることができる。さらに把手片が２本の切り込み線でなるので、開封のスタート性を良くし、容易に開封を可能にすることができる。
【００２６】
また、把手片の延長上に裏から把手片用裏半切れ線を設けたので、把手片用裏半切れ線に従い蓋表面が破れ、一見して開封した破れ跡が残るので、不正開封防止性に優れた紙製蓋とすることができる。
【００２７】
また、切り込み線の１／２以下で蓋の中心側に垂直に短い予備裏半切れ線を設け、該短い予備裏半切れ線の中心まで前記把手片用裏半切れ線を延長して設けることによって、製造工程で切り込み線と把手片用裏半切れ線の位置見当が合わない場合でも、短い予備裏半切れ線に沿って切れるので、確実な開封を可能にする。
【００２８】
さらにまた、上記２本の把手片用裏半切れ線の外側に、かつ平行に、周縁表半切れ線まで予備表半切れ線を付加したので、この開封に際し、把手片用裏半切れ線から外れて破れた場合でも、破れが予備表半切れ線で矯正され、周縁表半切れ線に連結されて切れるので、開封をより確実にすることができる。
【００２９】
また、２本の切り込み線のいずれか一方を、中心方向に周縁表半切れ線近傍まで延長して設けることによって、より容易に開封可能な紙製蓋とすることができる。
【００３０】
従って本発明は、特に食品等を収納する紙製もしくはプラスチック製容器（トレー）にシールする紙製蓋として、優れた実用上の効果を発揮する。

According to a fourth aspect of the present invention, any one of the two cut lines is provided so as to extend in the center direction to the vicinity of the peripheral half-cut line. This is a paper lid.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
As shown in the side sectional view of FIG. 2, the paper lid of the present invention has a seal portion (30) substantially the same shape as the flange portion (82) on the flange portion (82) of the square paper container (8). A paper lid (10) for sealing the two, as shown in the blank plan view of FIG. 2, two cut lines (22) are provided at one corner to provide a handle piece (20). The handle piece back half-cut line (24) is provided from the front end of the cut line (22) toward the center, and the two half-cut lines for handle piece back cut lines (24) are separated from each other. Peripheral back half-cut line (32) is given over the entire circumference along the inner edge of the seal portion (30), and the peripheral front half-cut line has a constant width (W) outside the peripheral back half-cut line (32). (34).
[0011]
In the above example, the rectangular container is the rectangular paper container (8), but it can also be a rectangular plastic container. However, as described in the section of the prior art, paper is preferable in consideration of resource problems and environmental problems related to waste.
[0012]
To open the paper lid (10) of the present invention, the handle piece (20) is picked up by hand, pulled up, peeled off from the flange portion (82) according to the cut line (22), and further pulled up for the handle piece. When the lid surface is torn to the peripheral surface half-cut line (34) according to the back half-cut line (24) and further lifted, as shown in the schematic side sectional view of FIG. The width of the back half-cut line (24) for the handle piece (24) causes delamination of cardboard, and the paper lid (10) is completed separately from the portion having the seal portion (30). It is possible to provide a paper lid that can be opened reliably and cleanly with no appearance of paper missing in the seal portion of the lid. In particular, since the handle piece (20) is composed of two cut lines (22), the startability of opening can be improved and the opening can be easily performed.
[0013]
Further, since the handle piece back half-cut line (24) is provided on the extension of the handle piece (20), when the handle piece (20) is pulled up as described above, the cover piece is covered according to the handle piece back half-cut line (24). Since the surface is torn and an open tear mark remains at a glance, the paper lid (10) can be provided with virginity (preventing unauthorized opening).
[0014]
The Paper lid (10) is a US basis weight 200g / m 2 ~500g / m 2 paperboard, at least one surface white coating Manila, coated cardboard it is necessary to print on the surface, or the like can be used Ivory . Furthermore, since it is necessary to seal the flange portion (82) of the square paper container (8) with heat sealing or the like, a film having excellent sealing ability such as a thin polyethylene film or polypropylene film of 15 μm to 80 μm is laminated on the back surface. Used. These films take into account the hygiene when the contents are foods, and also serve as moisture-proof.
[0015]
Further, the constant width (W) between the peripheral back half-cut line (32) and the peripheral front half-cut line (34) varies depending on the size of the paper lid (10), but about 2 to 3 mm is appropriate. If it is too large, delamination of the paperboard will not be smooth, and if it is too small, the peripheral back half cut line (32) and the peripheral front half cut line (34) are separated from the front and back of the lid by separate blades. In the manufacturing process provided in the form, the position (registration) does not match and there is a concern that the two may overlap each other. If they overlap, it will be completely cut out and open before opening. However, if a process of simultaneously inserting front and back half-cut lines is possible, it can be up to about 2 mm or less and about 1 mm.
[0016]
In the position (register) accuracy problem as described above, the notch line (22) formed by the handle piece (20) is the same, and this notch line (22) and the subsequent half-cut line for the handle piece (24) are provided. There is a case where it is shifted vertically and horizontally and not connected as a straight line. If they are not connected linearly in this way, they will be broken from the cut line (22), and reliable opening will not be possible. In order to solve such a problem, the invention of claim 2, as shown in an enlarged plan view in the vicinity of the handle piece (20) in FIG. A short preliminary back half-cut line (26) is provided vertically on the side, and the back half-cut line (24) for the handle piece is extended to the center of the short preliminary back half-cut line (26). .
[0017]
As described above, for example, the cut line (22) and the back half-cut line for the handle piece (24) can be obtained by adding an extension line of the short preliminary back half-cut line (26) and the handle piece back half-cut line (24). ), When opening the paper lid (10), it is cut off from the extension line of the short preliminary back half-cut line (26) and the grip piece back half-cut line (24) to ensure the opening. Can be.
[0018]
The reason why the position of the short back half cut line (26) is set to ½ or less of the cut line (22) in the above case is that it is unexpected if it is provided near the tip of the handle piece (20) beyond 1/2. This is because there is a risk of tearing from this short spare back half-cut line (26) before opening it during transportation.
[0019]
Furthermore, in order to make the opening more reliable, in the invention of claim 3, as shown in the enlarged plan view in the vicinity of the handle piece (20) in FIG. ) On the outer side and in parallel with the preliminary half-cut line (36) up to the peripheral half-cut line (34).
[0020]
By applying the preliminary front half-cut line (36) as described above, even when the paper lid (10) is opened, even if it breaks off from the back half-cut line (24) for the grip piece, it will be broken. Since it is corrected by this preliminary front half-cut line (36) and cut by being connected to the peripheral front half-cut line (34), the opening can be made more reliable.
[0021]
Moreover, as shown in the enlarged plan view in the vicinity of the handle piece (20) in FIG. 5, the invention of claim 4 is either one of the two cut lines (22) (the handle piece (20) in the case of FIG. 5). The cut line (22) on the left side when viewed from the direction is provided extending in the center direction to the vicinity of the half-cut line (34) on the peripheral surface.
[0022]
As shown in FIG. 5, by extending the left cut line (22) when viewed from the direction of the handle piece (20), a right-handed person opens the paper lid (10) and the right thumb The index finger is used to pick up the handle piece (20) and pull it up so that it can be opened outward, and the tear or cut can be quickly connected to the peripheral half-cut line (34), so it is easier and more reliable. Can be opened.
[0023]
Conversely, when the right cut line (22) is extended as viewed from the direction of the handle piece (20), a paper lid (10) that can be opened more easily for a left-handed person can be obtained.
[0024]
The paper lid (10) of the present invention is sealed by a flat flange (82) of a rectangular paper or plastic container (8), but the container is round, triangular or pentagonal. However, it can be used if the flange (82) is flat.
[0025]
【The invention's effect】
Since this invention is the above structure, there exist the following effects.
That is, in the paper lid that seals the flange portion of the rectangular container (tray) with a seal portion that is substantially the same shape as the flange portion, a handle piece with two score lines is provided at one corner, and the tip of the score line A back half-cut line for the handle piece is provided toward the center, and a peripheral back half-cut line is provided along the inner edge of the seal portion outside the center-side tip of the back half-cut line for the handle piece. By making a semi-periphery line with a certain width (about 2 to 3 mm) on the outside of the cut line, there is no paper mess in the seal part of the paper lid, and it is made of paper that can be opened cleanly and reliably in appearance. It can be a lid. Furthermore, since the handle piece is made of two cut lines, the startability of opening can be improved and the opening can be easily performed.
[0026]
In addition, since the back half-cut line for the handle piece is provided on the extension of the handle piece from the back, the lid surface is torn according to the back half-cut line for the handle piece, and a broken trace remains at first glance. It is possible to make a paper lid excellent in the above.
[0027]
Also, a short preliminary back half-cut line is provided perpendicularly to the center side of the lid at ½ or less of the cut line, and the handle piece back half-cut line is extended to the center of the short preliminary back half-cut line. Therefore, even when the position registration of the cut line and the back half-cut line for the handle piece does not match in the manufacturing process, the cut is made along the short preliminary back half-cut line, so that reliable opening is possible.
[0028]
Furthermore, since a preliminary front half-cut line is added to the outer half-cut line on the outer edge of the two handle pieces and parallel to the peripheral front half-cut line, when opening, from the back half-cut line for the handle piece Even when it breaks apart, the tear is corrected by the preliminary half-cut line and cut by being connected to the peripheral half-cut line, so that the opening can be made more reliable.
[0029]
Moreover, it can be set as the paper cover which can be opened more easily by providing either one of two cut lines extending in the center direction to the vicinity of the peripheral surface half-cut line.
[0030]
Therefore, the present invention exhibits an excellent practical effect particularly as a paper lid for sealing a paper or plastic container (tray) for storing food or the like.
