Abstract

PROBLEM TO BE SOLVED: To provide a lid for a food packaging container which lid allows an adhesive tape to be removed easily and is hardly torn off when the adhesive tape is removed from the lid.SOLUTION: The lid 1 for the food packaging container is formed by molding a synthetic resin sheet, has a vertically extended surface 5 fitted externally on a flange of a container body 8, and is entirely or partially subjected to an embossing process to form grain portions 7. The grain portions 7 has enhanced strength, which makes the lid 1 hard to tear. The grain portions 7 has irregularities making it difficult for an adhesive tape 10 to adhere to the grain portions. Hence the adhesive tape 10 is easily removed.

Description

本発明は、合成樹脂シートを熱成形して形成する食品包装用容器の蓋に関する。   The present invention relates to a lid for a food packaging container formed by thermoforming a synthetic resin sheet.

弁当用の容器や惣菜、刺身などの食材を包装する容器としては、容器本体の周囲に外側から嵌め合せる蓋を設けた容器が店舗などでよく見かけられる（下記特許文献１参照）。このような容器は、近年では、軽量化や材料の節約のため薄い合成樹脂シートで作製されることが多く、特に蓋は、厚み１５０μｍ〜３５０μｍの合成樹脂シートなどから成形することがある（下記特許文献２参照）。   As containers for packaging lunch boxes, side dishes, sashimi and other foods, containers provided with a lid that fits from the outside around the container body are often found in stores (see Patent Document 1 below). In recent years, such containers are often made of a thin synthetic resin sheet in order to reduce weight and save materials. In particular, the lid may be formed from a synthetic resin sheet having a thickness of 150 μm to 350 μm (described below). Patent Document 2).

このような容器は、例えば、蓋の周囲に内側に突出した凸部を設け、この凸部が容器本体のフランジ部に掛かるように形成し、嵌め合せるようにしてある。しかし、このような嵌め合わせでは蓋を持ち上げた場合に外れて開封してしまうおそれがあるため、図７に示すように、粘着テープで蓋と容器本体とをさらに貼り合わせてあることが多い。   For example, such a container is provided with a convex portion protruding inward around the lid, and is formed so that the convex portion is hooked on the flange portion of the container main body. However, in such a fitting, there is a possibility that the lid may come off and be opened when the lid is lifted. Therefore, as shown in FIG. 7, the lid and the container main body are often further bonded with an adhesive tape.

容器本体と蓋とを粘着テープで貼り合わせた場合、粘着テープを剥がそうとすると、容器本体及び蓋は合成樹脂から形成されているため表面が平滑であり、粘着テープが密着し、剥がしにくいことがあった。
さらには、蓋を薄い合成樹脂シートで成形した場合は、粘着テープを剥がす際に蓋が切り裂け、この裂けた箇所により手などを傷つけてしまうおそれがあった。 When the container body and lid are bonded with adhesive tape, if the adhesive tape is peeled off, the container body and lid are made of synthetic resin, so the surface is smooth and the adhesive tape is in close contact and difficult to peel off. was there.
Furthermore, when the lid is formed of a thin synthetic resin sheet, the lid may be torn when the adhesive tape is peeled off, and there is a possibility that a hand or the like may be damaged by the torn portion.

そこで、本発明の目的は、粘着テープを剥がす際に、剥がしやすくするとともに蓋を切り裂けにくくした食品包装用容器の蓋を提供することにある。   Accordingly, an object of the present invention is to provide a lid for a food packaging container that is easy to peel off when the adhesive tape is peeled off and is difficult to tear the lid off.

本発明の、食品包装用容器の蓋は、合成樹脂シートを成形してなり、容器本体のフランジ部に外側から嵌合可能な垂下面部を形成し、この垂下面部の表面の全部又は一部にシボ加工を施したことを特徴とする。   The lid of the container for food packaging of the present invention is formed by molding a synthetic resin sheet, and forms a drooping surface portion that can be fitted from the outside to the flange portion of the container body, and is formed on all or part of the surface of the drooping surface portion. It is characterized by having a textured finish.

このような構成とし、シボ加工を施した部分に粘着テープを貼り付けることにより、この部分は凹凸状に形成されているため、粘着テープが、密着しにくく剥がしやすくなる。また、シボ加工を施した部分は、凹凸状に形成されているため、この部分の強度が増し、粘着テープを剥がす際に蓋が切り裂けにくくなる。   By sticking the pressure-sensitive adhesive tape to the part subjected to the textured process, this part is formed in a concavo-convex shape, so that the pressure-sensitive adhesive tape is difficult to adhere and easily peeled off. Moreover, since the part which gave the embossing process is formed in uneven | corrugated shape, the intensity | strength of this part increases and it becomes difficult to tear a lid | cover when peeling an adhesive tape.

以下、本発明の食品包装用容器の蓋の一実施形態を、図面に基づいて説明する。   Hereinafter, one embodiment of a lid of a container for food packaging of the present invention is described based on a drawing.

本発明の一実施形態の食品包装用容器の蓋１は、図１に示すように、合成樹脂シートを真空圧空成形などして形成することができ、横長長方形状の天面部２と、その周囲に形成した側面部３と、その下端から外側に水平に延びるフランジ部４と、その周囲から垂下する垂下面部５とを備えている。
合成樹脂シートは、厚み１５０μｍ〜３５０μｍ、特に１８０μｍ〜２５０μｍであるのが好ましい。 As shown in FIG. 1, the lid 1 of the food packaging container according to the embodiment of the present invention can be formed by vacuum / pressure forming a synthetic resin sheet, and has a horizontally-long rectangular top surface portion 2 and its surroundings. , A flange portion 4 that extends horizontally from the lower end to the outside, and a drooping lower surface portion 5 that hangs down from the periphery thereof.
The synthetic resin sheet preferably has a thickness of 150 μm to 350 μm, particularly 180 μm to 250 μm.

垂下面部５の各隅部及び各面の中間付近には、横長楕円状に凹ませて内側に突出した嵌合部６が形成してある。また、垂下面部５の各面表面の中間付近は、シボ加工を施してシボ部７が形成してある。   In the vicinity of each corner of the drooping surface 5 and the middle of each surface, a fitting portion 6 that is recessed in an oblong elliptical shape and protrudes inward is formed. In addition, an embossed portion 7 is formed in the vicinity of the middle of each surface of the drooping surface portion 5 by applying an embossing process.

シボ部７は、図２に示すように、筋状溝を斜めに交差させた網目状に形成して、菱形状の微小突起７ａを多数形成してある。この筋状溝の幅は、０．２ｍｍ〜３．０ｍｍ、特に０．３ｍｍ〜１．０ｍｍにするのが好ましく、深さは、０．１ｍｍ〜１．５ｍｍ、特に０．２ｍ〜０．７ｍｍにするのが好ましい。また、各筋状溝の間隔は、０．２ｍｍ〜５．０ｍｍ、特に０．５ｍｍ〜２．０ｍｍにするのが好ましい。   As shown in FIG. 2, the embossed portion 7 is formed in a mesh shape in which the streak-like grooves are obliquely intersected, and a large number of rhomboid minute projections 7a are formed. The width of the streak groove is preferably 0.2 mm to 3.0 mm, particularly 0.3 mm to 1.0 mm, and the depth is 0.1 mm to 1.5 mm, particularly 0.2 m to 0.7 mm. Is preferable. The interval between the streak grooves is preferably 0.2 mm to 5.0 mm, particularly 0.5 mm to 2.0 mm.

上記実施形態では、垂下面部５の表面の一部にシボ加工を施してシボ部７を形成したが、全面にシボ加工を施してシボ部を形成してもよい。
また、シボ部７は筋状溝を斜め方向に形成した網目状ではなく、図３に示すように、横方向の筋状溝７ｂを複数形成した形状でもよく、図４に示すように、円状の微小突起７ｃを複数形成した形状でもよい。 In the above embodiment, the embossed portion 7 is formed by subjecting a part of the surface of the drooping lower surface portion 5, but the embossed portion may be formed by embossing the entire surface.
Further, the embossed portion 7 is not a mesh shape in which the streak grooves are formed in an oblique direction, but may have a shape in which a plurality of lateral streak grooves 7b are formed as shown in FIG. 3, and as shown in FIG. A shape in which a plurality of fine projections 7c are formed may be used.

容器本体８は、横長長方形の皿状に形成してあり、周囲に形成したフランジ部９が蓋１のフランジ部４と各嵌合部６との間に挟まり、図５に示すように、蓋１と容器本体８とが嵌合できるようにしてある。   The container body 8 is formed in a horizontally-long rectangular dish shape, and a flange portion 9 formed around the container body 8 is sandwiched between the flange portion 4 and each fitting portion 6 of the lid 1, and as shown in FIG. 1 and the container main body 8 can be fitted.

蓋１は、容器本体８と嵌合し、図５に示すように、容器本体８の底面からシボ部７を跨ぎ側面部３に至るように粘着テープ１０を貼り付けることができる。この粘着テープ１０は、凹凸状のシボ部７部分に密着しないため、この付近から剥がしやすいものである。また、垂下面部５には凹凸状のシボ加工を施してあるため、この付近の強度が高まり、粘着テープ１０を剥がす際に、蓋１が切り裂けることがなく、手などを傷つけるおそれがない。   As shown in FIG. 5, the lid 1 can be attached to the lid 1 so that the lid 1 extends from the bottom surface of the container body 8 across the embossed portion 7 to reach the side surface portion 3. Since this adhesive tape 10 is not in close contact with the concavo-convex textured portion 7 portion, it is easy to peel off from this vicinity. Moreover, since the concave and convex surface portion 5 is subjected to uneven texture processing, the strength in the vicinity thereof is increased, and when the adhesive tape 10 is peeled off, the lid 1 is not torn and there is no possibility of damaging a hand or the like.

本発明の他の形態としては、図６に示すように、フランジ部４にもシボ部７ｄを設けることができ、このようにすると、粘着テープがより剥がしやすくなるとともに強度が増し、蓋が切り裂けることがなくなる。この際、シボ部７ｄは、フランジ部４の全部又は一部に設けることができ、上記シボ部７と同様な形状とすることができる。   As another embodiment of the present invention, as shown in FIG. 6, the flange portion 4 can also be provided with a textured portion 7d. In this way, the adhesive tape can be more easily peeled off, the strength is increased, and the lid is torn. It will not be. At this time, the embossed portion 7 d can be provided on all or part of the flange portion 4 and can have the same shape as the embossed portion 7.

上記実施形態の構成態様は、本発明を限定するものとして挙げたものではなく、技術目的を共通にするかぎり変更は可能であり、本発明はそのような変更を含むものである。   The configuration aspect of the above embodiment is not intended to limit the present invention, but can be changed as long as the technical purpose is common, and the present invention includes such a change.
