Description

この発明は、収納物の取出しに際して容器の胴部分を開封して容易に取り出せるようにしたカップ状の包装用容器に関するものである。 The present invention relates to a cup-shaped packaging container that can be easily removed by opening the body portion of the container when the stored item is taken out.

カップ状の包装用容器から収納物を取り出す際に、例えばケーキ生地などをそのまま焼成して生地が包装用容器に一体に付着している場合や、焼成に限らず包装用容器内に収納物がほぼ隙間無く収納されているような場合には、収納物をきれいに取り出すことができないので、包装用容器の胴部を切り裂いて開封し容器底面の糸底部から切り離すことが望まれる。
包装用容器の胴部を開封する構造としては、例えば実公昭６０−２０５７５号公報の半切線付きカップでは、紙カップの胴貼部の外側の側辺の上端近傍を横外方に若干突出させて摘持片を形成し、該摘持片の下端から斜め下方に螺旋状に進行し最後に胴下方部を略水平に一周する紙層に達する深さの半切線を胴部ブランクの表面側より穿設すると共に前記半切線と略平行に進み、且つ摘持片の下端及び前記側辺上の点において前記半切線と合している紙層に達する深さの半切線を胴部ブランクの内面側より穿設した構造が開示されている。
上記構成では、半切線を設けたところ以外の場所は合成樹脂層により破れ難く、表面と裏面とで半切線をずらしているので内容物が滲み出てくることを防止することができるが、摘持片を形成する必要があり、また半切線は胴部の貼合部を複数回横断させる必要があり、途中で千切れることなく半切線に沿って底部まで一連に切り裂かないと収納物を糸底部からきれいに取り出すことができない。
また、展開線としてミシン目を用いた場合には、包装用容器の素材が紙や合成紙と合成樹脂の積層、または異なる合成樹脂などの複数の積層構造からなる場合には、引裂抵抗が大きくて綺麗に引き裂けない場合がある。
例えば、紙にＰＥＴフィルムを被覆した場合には、ＰＥＴフィルム側の引裂抵抗が強いので、単なるミシン目や一面だけのハーフカットだけでは引き裂いて胴部を開封することが困難となる。
また、ミシン目のピッチを短くしたり、切込みを深くすると、折れ曲がりやすくなり、容器の保形性を維持することができないという不具合があった。 When taking out the stored items from the cup-shaped packaging container, for example, when the cake dough is baked as it is and the dough is integrally attached to the packaging container, or the stored items are not limited to baking in the packaging container. In the case where the container is stored with almost no gap, it is not possible to cleanly remove the stored item. Therefore, it is desirable to tear off the body of the packaging container and open it and separate it from the thread bottom on the bottom of the container.
For example, in the case of a cup with a half-cut line in Japanese Utility Model Publication No. 60-20575, the upper end of the outer side of the paper cup body sticking part is slightly protruded laterally outward. A gripping piece is formed, and a half-cut line having a depth reaching a paper layer that spirals downward from the lower end of the gripping piece and finally goes around the lower part of the trunk substantially horizontally is formed from the surface side of the trunk blank. The inner surface of the body blank is formed with a half-cut line having a depth that reaches the paper layer that penetrates the half-cut line at a point on the lower end and the side edge of the gripping piece and that extends substantially parallel to the half-cut line. A structure drilled from the side is disclosed.
In the above configuration, the place other than where the half-cut line is provided is not easily torn by the synthetic resin layer, and since the half-cut line is shifted between the front and back surfaces, the content can be prevented from oozing out. It is necessary to form a holding piece, and the half-cut line needs to cross the bonding part of the trunk part a plurality of times. It cannot be removed cleanly from the bottom.
In addition, when perforation is used as the development line, the tear resistance is high when the packaging container material is made of multiple laminated structures such as paper, synthetic paper and synthetic resin, or different synthetic resins. And may not tear cleanly.
For example, when paper is covered with a PET film, the tear resistance on the side of the PET film is strong, so that it is difficult to tear and open the body part only by a perforation or a half-cut only on one side.
Moreover, when the pitch of the perforation is shortened or the cut is deepened, there is a problem that the container tends to be bent and the shape retaining property of the container cannot be maintained.

(1) Since the tear line is composed of a pair of half cuts formed on the outer surface side and the inner surface side of the body portion at an interval that allows tearing, the tear resistance is applied to the inner surface side or the outer surface side of the body portion. Even if a high resin film is used and the material cannot be torn by a single perforation or a single half cut, each of them is half-cut, so the whole or main part of the barrel is threaded at the bottom of the container It can be separated from the bottom and taken out without damaging the contents in the container.
(2) The longitudinal tear line is inclined in the direction opposite to the tear direction of the lateral tear line from the upper end to the midway position, curved at the midway position, tilted in the tear direction of the lateral tear line, and connected to the lateral tear line, It can withstand the pressure applied from above during curl molding and is not easily buckled, and can be connected to a horizontal tear line without interruption during tearing.
(3) By forming the upper end of the vertical tear line in the middle of the edge of the concave notch formed in the upper part of the trunk, it is possible to start tearing without forming a trigger piece.
(4) The longitudinal tear line can be easily torn while maintaining the shape-retaining property of the container by the strength of the bonding part by arranging it in the vicinity of the bonding part of the trunk part.
(5) The horizontal tear line tears the body by placing the half cut on the inner surface side slightly above the upper end of the yarn bottom and the half cut on the outer surface side below the upper end of the yarn bottom. The remaining part of the cutout does not get in the way when removing the storage.
(6) A longitudinal tear line is provided in a pair on the left and right sides of the bonding part of the trunk part, and one or more longitudinal tearing relay lines connected to the upper end of the trunk part and the horizontal tear line are provided between the longitudinal tear lines. Thus, the body can be torn apart by dividing it into a plurality of times.
(7) By forming the longitudinal tearing relay line into a curved line from the lower end toward the tearing direction while curving toward the tearing direction, the trunk can be torn cleanly in the middle position.
(8) The upper end of the longitudinal tearing relay line can also be reliably torn by forming it at the midway position of the edge of the concave notch formed at the upper part of the trunk.
(9) By forming the collar on the upper end of the body excluding the notch, the lid that covers the upper opening of the container can be hooked, and no half cut is formed on the collar, so the collar There is no cracking.
(10) By forming a plurality of notches into a recess and forming them at regular intervals, not only the appearance aesthetics but also the shape retention can be improved.

この発明は、胴部の外面側と内面側にそれぞれ引裂可能な間隔を隔てて形成された一対のハーフカットからなる引裂線を設けて、胴部の全部又は主要部を容器底部の糸底部から分離して引き離すことを実現した。 The present invention provides a tear line composed of a pair of half cuts formed on the outer surface side and the inner surface side of the body part with a tearable interval, respectively, so that all or a main part of the body part is separated from the yarn bottom part of the container bottom part. Realized separation and separation.

図２に示す実施例１の包装用容器１は、カップ状からなっており、胴部２が紙又は合成樹脂を複数積層してなる素材、本実施例では外面側を紙とし、内面側にＰＥＴフィルムを貼り合わせた素材からなっており、胴部２の主要部を引き裂いて容器底部の糸底部３と分離する引裂線を設けている。
上記胴部２の素材の一例としては、紙の厚みが０．２０〜０．５０ｍｍ、ＰＥＴフィルムの厚みが１５〜６０μｍからなっており、紙は単層抄きより多層抄きが好ましいが、この発明では特に限定されない。 The packaging container 1 of Example 1 shown in FIG. 2 has a cup shape, and the body portion 2 is made of a material obtained by laminating a plurality of papers or synthetic resins. In this example, the outer surface side is paper, and the inner surface side. It consists of the raw material which bonded PET film, The tear line which tears the main part of the trunk | drum 2 and isolate | separates from the thread bottom part 3 of a container bottom part is provided.
As an example of the material of the body part 2, the thickness of the paper is 0.20 to 0.50 mm and the thickness of the PET film is 15 to 60 μm. This invention is not particularly limited.

引裂線は、胴部２の外面側と内面側にそれぞれ引裂可能な間隔を隔てて形成された一対のハーフカットからなっている。
本実施例で、上記引裂線は、胴部２の下部で胴部２の内壁面に接着される容器底面の糸底部３の外周面に沿ってその全周に形成された横引裂線４、５と、胴部２の上端と前記横引裂線４，５との間に掛け渡されると共に下端で同一面側の横引裂線４、５と一連につながる縦引裂線６、７とを有している。
上記引裂線は、図１の胴部２のブランクに示すように、実線が胴部の外面側に形成されるハーフカット、点線が胴部の内面側に形成されるハーフカットである。 The tear line is composed of a pair of half cuts formed on the outer surface side and the inner surface side of the body portion 2 with a tearable interval.
In this embodiment, the tear line is formed along the outer peripheral surface of the yarn bottom part 3 of the bottom surface of the container bonded to the inner wall surface of the body part 2 at the lower part of the body part 2, 5, spanning between the upper end of the body portion 2 and the horizontal tear lines 4, 5, and the horizontal tear lines 4, 5 on the same surface side at the lower end and the vertical tear lines 6, 7 connected in series. ing.
The tear line is a half cut in which a solid line is formed on the outer surface side of the body portion and a dotted line is formed on the inner surface side of the body portion as shown in the blank of the body portion 2 in FIG.

横引裂線４、５は、胴部２の外面側に形成されるハーフカット５が下方となり、内面側に形成されるハーフカット４が上方に配置されている。
縦引裂線６、７は、胴部２の外面側に形成されるハーフカット６が引裂方向の基端側となり、前記横引裂線の外面側のハーフカット５と連接され、内面側に形成されるハーフカット７が引裂方向の先端側となり前記横引裂線の内面側のハーフカット４と連接されている。 In the horizontal tear lines 4 and 5, the half cut 5 formed on the outer surface side of the body portion 2 is on the lower side, and the half cut 4 formed on the inner surface side is disposed on the upper side.
The longitudinal tear lines 6, 7 are formed on the inner surface side by being connected to the half cut 5 on the outer surface side of the horizontal tear line, with the half cut 6 formed on the outer surface side of the body portion 2 being the proximal end side in the tear direction. The half-cut 7 is connected to the half-cut 4 on the inner side of the lateral tear line.

この発明では、後述のように、本実施例では、横引裂線４、５と、縦引裂線６、７だけで構成されていてもよいが、本実施例では縦引裂線（説明の便宜上、一方の符号を６、７とし、他方の符号を６’、７’とする）を胴部２の貼合部２１を挟んで、その近傍に一対に形成しており、更に、該縦引裂線６、７と６’、７’の間に縦引裂中継線８、９を形成している。
また、ハーフカットは図５に例示するように、内面側が引裂抵抗の高いＰＥＴフィルム側を含めて紙の一部まで含めてカットされた例を図示したが、引裂抵抗が低い樹脂フィルムの場合は、その一部がカットされるものでもよく、カットの深さは素材に応じて引裂できるように適宜設計することができる。 In the present invention, as described later, in the present embodiment, it may be composed of only the horizontal tear lines 4 and 5 and the longitudinal tear lines 6 and 7, but in this embodiment, the longitudinal tear line (for convenience of explanation, One of the symbols 6 and 7 and the other of the symbols 6 'and 7') is formed in a pair in the vicinity of the bonding portion 21 of the body portion 2, and the longitudinal tear line. Longitudinal tear lines 8 and 9 are formed between 6 and 7 and 6 'and 7'.
In addition, as illustrated in FIG. 5, the half cut illustrates an example in which the inner surface side is cut to include a part of paper including the PET film side with high tear resistance, but in the case of a resin film with low tear resistance, Some of them may be cut, and the depth of the cut can be appropriately designed so that it can be torn according to the material.

縦引裂中継線８、９は、胴部２の外面側に形成されるハーフカット８が引裂方向の先端側となり、前記横引裂線の外面側のハーフカット５と連設されており、胴部２の内面側に形成されるハーフカット９が引裂方向の基端側となり、前記横引裂線の内面側のハーフカット４と連設されている。
この発明では、各引裂線の内面側のハーフカットと外面側のハーフカットの配置は、胴部２の素材に応じて配置でき、図示例では内面側の引裂抵抗が高い場合であるが、外面側の引裂抵抗が高い場合には逆に配置（図１の実線が内面側、点線が外面側）に形成してもよい。 The longitudinal tearing relay wires 8 and 9 have a half cut 8 formed on the outer surface side of the body portion 2 as a leading end side in the tearing direction, and are connected to the half cut 5 on the outer surface side of the lateral tear line. A half cut 9 formed on the inner surface side of 2 is a base end side in the tearing direction, and is continuous with the half cut 4 on the inner surface side of the lateral tear line.
In this invention, the arrangement of the half cut on the inner surface side and the half cut on the outer surface side of each tear line can be arranged according to the material of the body portion 2, and in the illustrated example, the tear resistance on the inner surface side is high. When the tear resistance on the side is high, it may be formed in reverse (the solid line in FIG. 1 is the inner surface side and the dotted line is the outer surface side).

上記横引裂線４、５と、縦引裂線６、７と、引裂中継線８、９とは、それぞれ外面側と内面側に形成される一対のハーフカットの間隔をハーフカット間で引裂可能な間隔に設定する必要があり、図示例では、横引裂線４、５と、縦引裂線６、７は、それぞれ３ｍｍ間隔とし、引裂中継線８、９は４ｍｍ間隔としているが、前記間隔は、素材に応じて適宜増減することができる。 The horizontal tear lines 4, 5, the vertical tear lines 6, 7, and the tear relay lines 8, 9 can tear between a pair of half cuts formed on the outer surface side and the inner surface side between the half cuts. In the illustrated example, the horizontal tear lines 4 and 5 and the vertical tear lines 6 and 7 are set to be 3 mm intervals, and the tear relay lines 8 and 9 are set to 4 mm intervals. The number can be appropriately increased or decreased depending on the material.

本実施例で、縦引裂線６、７と６’，７’は、胴部２の貼合部２１の近傍に配置されており、上端から中途位置までが引裂方向と反対方向に傾斜し、中途位置で湾曲して横引裂線４、５と連なる下端まで引裂方向に傾斜してなる略く字状に形成されている。 In this example, the longitudinal tear lines 6, 7 and 6 ', 7' are arranged in the vicinity of the bonding part 21 of the body part 2, and the upper end to the midway position is inclined in the direction opposite to the tearing direction, It is formed in a substantially square shape that is bent in the middle position and is inclined in the tearing direction to the lower end continuous with the horizontal tear lines 4 and 5.

該縦引裂線６，７と６’、７’との間に形成される縦引裂中継線８，９は、横引裂線４、５と連なる下端から引裂方向に向かって湾曲しながら胴部上端にいたる略ノ字状の曲線からなっている。
これにより縦引裂線６，７から引き裂かれた略半分の胴片部を引裂方向に沿ってスムーズに切り離すことができる。
ここで、例えば、外面側に形成されるハーフカット８の上端は、胴部の上端、図示例では後述の切欠部１１の縁部と接することなく、僅かに、例えば２ｍｍ程度離しておくことで、内面側のハーフカット９が切欠部の縁部に接していても、容器の上端形状の保形性を維持することができる。 Longitudinal tear lines 8 and 9 formed between the longitudinal tear lines 6 and 7 and 6 'and 7' are curved in the tearing direction from the lower ends connected to the lateral tear lines 4 and 5, and the upper end of the trunk portion. It consists of a roughly square-shaped curve.
Thereby, the substantially half trunk piece part torn from the vertical tear lines 6 and 7 can be smoothly cut | disconnected along a tear direction.
Here, for example, the upper end of the half cut 8 formed on the outer surface side is slightly separated by, for example, about 2 mm without coming into contact with the upper end of the body portion, in the illustrated example, the edge of a notch portion 11 described later. Even if the half cut 9 on the inner surface side is in contact with the edge of the notch, the shape retaining property of the upper end shape of the container can be maintained.

また、本実施例では、胴部２の上端には、鍔部１０と、切欠部１１とが形成されている。
鍔部１０は容器１に蓋部を掛止めるために形成されるが、鍔部１０にハーフカットを形成すると鍔部１０が割れて保形性が維持できない虞れがあるため、本実施例では胴部２の上端に切欠部１１を形成している。
ここで鍔部１０は、円形状にカールされたものでも、円弧状にカールされたものでも、外方へ突出するフランジ片であってもよく、要するに蓋部に掛止可能な構造であればよい。 In the present embodiment, a flange portion 10 and a notch portion 11 are formed at the upper end of the body portion 2.
Although the collar part 10 is formed in order to hang a lid part on the container 1, if the half cut is formed in the collar part 10, the collar part 10 may be broken and the shape retaining property may not be maintained. A notch 11 is formed at the upper end of the body 2.
