以下に図面を参照して本発明の実施形態を説明する。図１、図２は本実施形態の包装容器１の斜視図及び上面図であり、図３は図２のＡ−Ａ断面図である。 An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 are a perspective view and a top view of the packaging container 1 of the present embodiment, and FIG. 3 is a sectional view taken along the line AA of FIG.

包装容器１は、蓋部３０と、容器部４０と、を備える。容器部４０は、収納部１０と、延設部２０と、分離部２２と、を有し、樹脂成形品から成る。収納部１０は、上面が開口した扁平のボウル状に形成される。具体的には、収納部１０の深さを１０ｍｍ以下に形成することにより、包装容器１の携帯性を向上できる。収納部１０の内部には内容物（不図示）が収容される。内容物としては、例えば、液体を含む医療品が収容される。具体的には、潤滑剤に浸漬された避妊具等が挙げられる。 The packaging container 1 includes a lid portion 30 and a container portion 40. The container portion 40 includes a storage portion 10, an extension portion 20, and a separation portion 22, and is made of a resin molded product. The storage portion 10 is formed in the shape of a flat bowl with an open upper surface. Specifically, the portability of the packaging container 1 can be improved by forming the depth of the storage portion 10 to 10 mm or less. Contents (not shown) are stored inside the storage unit 10. As the contents, for example, a medical product containing a liquid is contained. Specific examples thereof include contraceptives immersed in a lubricant.

延設部２０は、収納部１０の周縁から外周方向に延び、凸部２３を有する。延設部２０の外周縁は、上面視において矩形状の名刺サイズ等の把持可能な大きさに形成される。 The extending portion 20 extends in the outer peripheral direction from the peripheral edge of the accommodating portion 10 and has a convex portion 23. The outer peripheral edge of the extension portion 20 is formed in a size that can be grasped, such as a rectangular business card size in a top view.

凸部２３は、収納部１０を挟んで分離部２２と対向する位置に配置され、蓋部３０の反対方向に突出する。凸部２３は、上面視において環状であり、分離部２２側に凸の曲線状に形成される。これにより、手指を凸部２３の形状に沿って当接させて凸部２３を安定して支持できる。また、凸部２３を分離部２２側へ強い力で押圧することができる。なお、凸部２３は、上面視において環状以外の形状に形成してもよい。例えば、凸部２３をドット状に複数形成したり、線状に形成してもよい。凸部２３を線状に形成する場合に、凸部２３を短手方向Ｘに延びるように形成し、長手方向Ｙに複数配置することが好ましい。このとき、収納部１０に近い側に配置される凸部２３の突出量を収納部１０から遠い側に配置される凸部２３の突出量よりも大きくすることが好ましい。これにより、手指で凸部２３をより安定して支持できる。 The convex portion 23 is arranged at a position facing the separating portion 22 with the accommodating portion 10 interposed therebetween, and projects in the opposite direction of the lid portion 30. The convex portion 23 is annular in the top view, and is formed in a convex curved shape on the separation portion 22 side. As a result, the fingers can be brought into contact with each other along the shape of the convex portion 23 to stably support the convex portion 23. Further, the convex portion 23 can be pressed toward the separation portion 22 side with a strong force. The convex portion 23 may be formed in a shape other than the annular shape when viewed from above. For example, a plurality of convex portions 23 may be formed in a dot shape or may be formed in a linear shape. When the convex portion 23 is formed linearly, it is preferable that the convex portion 23 is formed so as to extend in the lateral direction X and a plurality of the convex portions 23 are arranged in the longitudinal direction Y. At this time, it is preferable that the amount of protrusion of the convex portion 23 arranged on the side closer to the storage portion 10 is larger than the amount of protrusion of the convex portion 23 arranged on the side farther from the storage portion 10. As a result, the convex portion 23 can be supported more stably by the fingers.

分離部２２は、延設部２０に隣接して配置され、蓋部３０の反対方向に突出する突起部２２ａを有する。突起部２２ａを設けることにより、分離部２２の厚みが大きくなり、分離部２２を強い力で摘持することができる。また、突起部２２ａによって分離部２２に凹凸が形成され、突起部２２ａを摘持する際に手指を滑り止めすることができる。また、突起部２２ａを設けることにより、分離部２２の剛性が向上し、分離部２２が、反って変形することを防止できる。 The separating portion 22 is arranged adjacent to the extending portion 20 and has a protruding portion 22a protruding in the opposite direction of the lid portion 30. By providing the protruding portion 22a, the thickness of the separating portion 22 is increased, and the separating portion 22 can be gripped with a strong force. In addition, the protrusions 22a form irregularities on the separation portion 22, so that the fingers can be prevented from slipping when the protrusions 22a are gripped. Further, by providing the protruding portion 22a, the rigidity of the separating portion 22 is improved, and the separating portion 22 can be prevented from being warped and deformed.

容器部４０は、延設部２０と分離部２２との間に配置される切断線２１が形成される。切断線２１は、短手方向Ｘに延び、容器部４０の蓋部３０の反対側の面から厚み方向に所定の深さで切断された非貫通の切込みから成る。容器部４０は、分離部２２を切断線２１に沿って屈曲させることにより、切断線２１に沿って容易に破断する。すなわち、分離部２２は、延設部２０に対して分離可能状態にある。なお、分離前の分離部２２は、延設部２０と連結しており、開封前の包装容器１の携帯性が低下することを防止できる。 In the container portion 40, a cutting line 21 arranged between the extending portion 20 and the separating portion 22 is formed. The cutting line 21 extends in the lateral direction X and comprises a non-penetrating notch cut at a predetermined depth in the thickness direction from the surface opposite to the lid portion 30 of the container portion 40. The container portion 40 is easily broken along the cutting line 21 by bending the separating portion 22 along the cutting line 21. That is, the separating portion 22 is in a separable state with respect to the extending portion 20. The separation portion 22 before separation is connected to the extension portion 20, and it is possible to prevent the portability of the packaging container 1 before opening from being lowered.

蓋部３０は、後述する積層フィルム５０から成り、収納部１０を覆う。蓋部３０は、熱接着部（第１熱接着部）３１により延設部２０に固着する。熱接着部３１は、収納部１０を囲む環状に形成される。これにより、内容物は、収納部１０の内部に密封して収納される。また、蓋部３０は、熱接着部（第２熱接着部）３２により分離部２２に固着する。熱接着部３２は、熱接着部３１よりも外周側に配置される。これにより、分離部２２が延設部２０に対して分離した場合でも、分離部２２は蓋部３０に固着している。また、蓋部３０は、熱接着部３３により延設部２０に固着する。熱接着部３３は、収容部１０を挟んで分離部２２とは反対側の角部に配置される。これにより、蓋部３０の角部が捲れることを防止できる。なお、切断線２１の代わりに、延設部２０の下面から厚み方向に貫通する切込みを形成して分離部２２を予め収納部１０に対して分離状態にしてもよい。 The lid portion 30 is made of a laminated film 50 described later and covers the storage portion 10. The lid portion 30 is fixed to the extension portion 20 by the heat-bonding portion (first heat-bonding portion) 31. The heat-bonding portion 31 is formed in an annular shape surrounding the storage portion 10. As a result, the contents are sealed and stored inside the storage unit 10. Further, the lid portion 30 is fixed to the separation portion 22 by the heat-bonding portion (second heat-bonding portion) 32. The heat-bonded portion 32 is arranged on the outer peripheral side of the heat-bonded portion 31. As a result, even when the separating portion 22 is separated from the extending portion 20, the separating portion 22 is fixed to the lid portion 30. Further, the lid portion 30 is fixed to the extension portion 20 by the heat bonding portion 33. The heat-bonding portion 33 is arranged at a corner portion on the side opposite to the separating portion 22 with the accommodating portion 10 interposed therebetween. As a result, it is possible to prevent the corner portion of the lid portion 30 from being rolled up. Instead of the cutting line 21, a notch penetrating from the lower surface of the extending portion 20 in the thickness direction may be formed to separate the separating portion 22 from the accommodating portion 10 in advance.

熱接着部３１は、分離部２２側に突出する突出部３１ａを２個有し、突出部３１ａは、短手方向Ｘに並設される。包装容器１の開封時、切断線２１に沿って容器部４０を破断し、分離部２２を長手方向Ｙの凸部２３側に引張り、分離部２２と収納部１０とを近づける。このとき、突出部３１ａ上の蓋部３０に最初に剥離する力が集中する。これにより、蓋部３０を突出部３１ａ上から長手方向Ｙに容易に剥離することができる。また、突出部３１ａを複数並設することにより、突出部３１ａが並ぶ方向（短手方向Ｘ）に直交する方向（長手方向Ｙ）に蓋部３０を容易に延設部２０から剥離することができる。なお、突出部３１ａは、１個でもよく、３個以上でもよい。 The heat-bonded portion 31 has two protruding portions 31a protruding toward the separating portion 22, and the protruding portions 31a are arranged side by side in the lateral direction X. When the packaging container 1 is opened, the container portion 40 is broken along the cutting line 21, the separation portion 22 is pulled toward the convex portion 23 in the longitudinal direction Y, and the separation portion 22 and the storage portion 10 are brought close to each other. At this time, the force of first peeling is concentrated on the lid portion 30 on the protruding portion 31a. As a result, the lid portion 30 can be easily peeled off from above the protruding portion 31a in the longitudinal direction Y. Further, by arranging a plurality of the protruding portions 31a side by side, the lid portion 30 can be easily peeled off from the extending portion 20 in the direction (longitudinal direction Y) orthogonal to the direction in which the protruding portions 31a are lined up (short direction X). it can. The number of protruding portions 31a may be one or three or more.

図４は蓋部３０を構成する積層フィルム５０の層構成を示す断面図である。積層フィルム５０は外面側から基材層５１、フィルムバリア層５２、熱接着性樹脂層５３を順に積層して形成される。 FIG. 4 is a cross-sectional view showing the layer structure of the laminated film 50 constituting the lid portion 30. The laminated film 50 is formed by laminating a base material layer 51, a film barrier layer 52, and a thermosetting resin layer 53 in this order from the outer surface side.

基材層５１は、包装容器１に印刷適性、耐突き刺し性（耐ピンホール性）等を付与するものである。基材層５１としては、ナイロン、ポリエチレンテレフタレート、ポリブチレンテレフタレート等の公知の樹脂を任意に選択することができる。 The base material layer 51 imparts printability, puncture resistance (pinhole resistance), and the like to the packaging container 1. As the base material layer 51, known resins such as nylon, polyethylene terephthalate, and polybutylene terephthalate can be arbitrarily selected.

フィルムバリア層５２は、蓋部３０の耐ガス透過性等をより向上させることができ、アルミニウム箔等の金属箔が好適に用いられる。 The film barrier layer 52 can further improve the gas permeability of the lid portion 30, and a metal foil such as an aluminum foil is preferably used.

熱接着性樹脂層５３は延設部２０に熱接着可能な樹脂から成り、蓋部３０が引き剥がされるため、イージーピール性を有するものが用いられる。この時、熱接着性樹脂層５３として凝集剥離タイプの樹脂であってもよく界面剥離タイプの樹脂であってもよい。凝集剥離タイプの樹脂として、ポリエチレン（ＰＥ）、ポリプロピレン（ＰＰ）のブレンド樹脂を用いることができる。 The heat-adhesive resin layer 53 is made of a resin that can be heat-bonded to the extending portion 20, and the lid portion 30 is peeled off, so that a resin layer having easy peeling property is used. At this time, the heat-adhesive resin layer 53 may be a cohesive peeling type resin or an interface peeling type resin. As the coagulation peeling type resin, a blended resin of polyethylene (PE) and polypropylene (PP) can be used.

図５は容器部４０を構成する積層体６０の層構成を示す断面図である。積層体６０は内面側からシール層６１、容器バリア層６２、保護層６３を順に積層して形成される。 FIG. 5 is a cross-sectional view showing the layer structure of the laminated body 60 constituting the container portion 40. The laminated body 60 is formed by laminating the seal layer 61, the container barrier layer 62, and the protective layer 63 in this order from the inner surface side.

容器バリア層６２は、硬質の樹脂から成り、変形し難い。これにより、開封時に凸部２３を押圧したときに収納部１０及び延設部２０が変形することを防止できる。具体的には、エチレンービニルアルコール共重合体（ＥＶＯＨ）、環状オレフィン・コポリマー（ＣＯＣ）、ポリスチレン（ＰＳ）を用いることができる。ポリスチレンは、切断線２１に沿って分離部２２を屈曲させることにより、容易に破断する。このため、分離部２２を切断線２１に沿って延設部２０に対して容易に分離することができ好ましい。 The container barrier layer 62 is made of a hard resin and is not easily deformed. As a result, it is possible to prevent the storage portion 10 and the extension portion 20 from being deformed when the convex portion 23 is pressed during opening. Specifically, ethylene-vinyl alcohol copolymer (EVOH), cyclic olefin copolymer (COC), and polystyrene (PS) can be used. Polystyrene is easily broken by bending the separating portion 22 along the cutting line 21. Therefore, the separating portion 22 can be easily separated from the extending portion 20 along the cutting line 21, which is preferable.

シール層６１及び保護層６３は、容器バリア層６２の両面にそれぞれ製膜して形成され、具体的には、ポリエチレン（ＰＥ）又はポリプロピレン（ＰＰ）を用いることができる。シール層６１を設けることにより、容器部４０と蓋部３０とのシール強度を向上させて収納部１０内の密封性を向上できる。また、保護層６３を設けることにより、収納部１０内部のガスバリア性を向上させることができ、内容物の劣化を防止することができる。 The seal layer 61 and the protective layer 63 are formed by forming a film on both surfaces of the container barrier layer 62, and specifically, polyethylene (PE) or polypropylene (PP) can be used. By providing the seal layer 61, the sealing strength between the container portion 40 and the lid portion 30 can be improved, and the sealing property inside the storage portion 10 can be improved. Further, by providing the protective layer 63, the gas barrier property inside the storage portion 10 can be improved, and deterioration of the contents can be prevented.

なお、本実施形態では、積層体６０は、シール層６１、容器バリア層６２、保護層６３の３層で構成したが、本発明はこれに限定されない。例えば、保護層６３を省いて２層で構成してもよい。また、積層体６０の代わりに容器部４０を単相の樹脂で構成してもよい。この場合、単相の樹脂としてポリプロピレンを好適に用いることができる。また、容器部４０を構成する樹脂の種類によっては、切断線２１に沿って分離部２２を屈曲させた場合でも破断し難いことがある。この場合、分離部２２を予め収納部１０に対して分離状態にすることが好ましい。 In the present embodiment, the laminate 60 is composed of three layers of a seal layer 61, a container barrier layer 62, and a protective layer 63, but the present invention is not limited thereto. For example, the protective layer 63 may be omitted and composed of two layers. Further, the container portion 40 may be made of a single-phase resin instead of the laminated body 60. In this case, polypropylene can be preferably used as the single-phase resin. Further, depending on the type of resin constituting the container portion 40, it may be difficult to break even when the separating portion 22 is bent along the cutting line 21. In this case, it is preferable to separate the separation unit 22 from the storage unit 10 in advance.

切断線２１は、切刃等で保護層６３及び容器バリア層６２を厚み方向に所定深さで切断して形成される。 The cutting line 21 is formed by cutting the protective layer 63 and the container barrier layer 62 at a predetermined depth in the thickness direction with a cutting blade or the like.

図６〜図８は、包装容器１の使用方法を示しており、図６は、包装容器１を蓋部３０側から視た斜視図である。また、図７は、包装容器１を蓋部３０の反対側から視た斜視図であり、図８は、包装容器１を側方から視た断面図である。 6 to 8 show how to use the packaging container 1, and FIG. 6 is a perspective view of the packaging container 1 as viewed from the lid portion 30 side. Further, FIG. 7 is a perspective view of the packaging container 1 viewed from the opposite side of the lid portion 30, and FIG. 8 is a cross-sectional view of the packaging container 1 viewed from the side.

包装容器１の使用方法は、まず、包装容器１を把持しながら蓋部３０の一端が固着する分離部２２を親指Ｆ１と人差し指Ｆ２で摘持し、分離部２２を切断線２１に沿って上方に屈曲させる。これにより、容器部４０は切断線２１に沿って破断し、分離部２２が延設部２０に対して分離状態になる。 To use the packaging container 1, first, while grasping the packaging container 1, the separating portion 22 to which one end of the lid portion 30 is fixed is grasped by the thumb F1 and the index finger F2, and the separating portion 22 is moved upward along the cutting line 21. Bend to. As a result, the container portion 40 is broken along the cutting line 21, and the separating portion 22 is separated from the extending portion 20.

なお、予め、分離部２２が、延設部２０に対して分離状態にある場合、容器部４０を切断線２１に沿って破断する動作を省くことができる。 When the separating portion 22 is separated from the extending portion 20 in advance, the operation of breaking the container portion 40 along the cutting line 21 can be omitted.

次に、分離部２２を摘持する親指Ｆ１と人差し指Ｆ２とを延設部２０に当接させた状態で、中指Ｆ３で凸部２３を支持しながら、分離部２２を凸部２３側に引っ張る。これにより、分離部２２が、収納部１０側に引っ張られ、分離部２２とともに蓋部３０が延設部２０から剥離して収納部１０が開封される。このとき、容器部４０は樹脂成形品から成り変形し難い。このため、凸部２３を分離部２２側により強い力で押圧することができる。これにより、片手で収納部１０を容易に開封することができ、開封時の包装容器１の利便性を向上できる。 Next, with the thumb F1 and the index finger F2 holding the separating portion 22 in contact with the extending portion 20, the separating portion 22 is pulled toward the convex portion 23 while supporting the convex portion 23 with the middle finger F3. .. As a result, the separation portion 22 is pulled toward the storage portion 10, the lid portion 30 is peeled off from the extension portion 20 together with the separation portion 22, and the storage portion 10 is opened. At this time, the container portion 40 is made of a resin molded product and is not easily deformed. Therefore, the convex portion 23 can be pressed with a stronger force on the separation portion 22 side. As a result, the storage unit 10 can be easily opened with one hand, and the convenience of the packaging container 1 at the time of opening can be improved.

なお、本実施形態では、親指Ｆ１と人差し指Ｆ２と中指Ｆ３により蓋部３０を開封したが、他の方法で包装容器１を開封してもよい、例えば、分離部２２を延設部２０に対して分離した後、分離部２２に人差し指Ｆ２を掛けて分離部２２と凸部２３とを接近させながら収納部１０を開封してもよい。また、分離部２２を親指Ｆ１と人差し指Ｆ２とで摘持しながら、凸部２３を中指Ｆ３で分離部２２側に押圧して収納部１０を開封してもよい。また、中指Ｆ３の代わりに薬指で凸部２３を支持又は押圧してもよい。 In the present embodiment, the lid portion 30 is opened by the thumb F1, the index finger F2, and the middle finger F3, but the packaging container 1 may be opened by another method, for example, the separation portion 22 is attached to the extension portion 20. After the separation, the storage portion 10 may be opened while the index finger F2 is hung on the separation portion 22 and the separation portion 22 and the convex portion 23 are brought close to each other. Further, the storage portion 10 may be opened by pressing the convex portion 23 toward the separation portion 22 side with the middle finger F3 while grasping the separation portion 22 with the thumb F1 and the index finger F2. Further, the convex portion 23 may be supported or pressed by the ring finger instead of the middle finger F3.

本実施形態によると、包装容器１は、延設部２０に隣接する分離部２２が切断線２１により延設部２０に対して分離状態または分離可能状態で蓋部３０に熱接着される。このため、包装容器１を把持しながら分離部２２を延設部２０から分離し、分離部２２を手指で支持して蓋部３０を分離部２２ととともに引き剥がすことができる。これにより、片手で収納部１０を容易に開封することができ、開封時の包装容器１の利便性を向上できる。また、収納部１０に収納された内容物は、包装容器１の携帯時に破損し難い。 According to the present embodiment, in the packaging container 1, the separating portion 22 adjacent to the extending portion 20 is heat-bonded to the lid portion 30 by the cutting line 21 in a separated state or a separable state with respect to the extending portion 20. Therefore, the separation portion 22 can be separated from the extension portion 20 while grasping the packaging container 1, the separation portion 22 can be supported by fingers, and the lid portion 30 can be peeled off together with the separation portion 22. As a result, the storage unit 10 can be easily opened with one hand, and the convenience of the packaging container 1 at the time of opening can be improved. Further, the contents stored in the storage unit 10 are not easily damaged when the packaging container 1 is carried.

また、容器部４０は、延設部２０と分離部２２との間に配置されるとともに厚み方向に所定の深さで切断された非貫通の切込みから成る切断線２１が形成される。これにより、容器部４０は、切断線２１に沿って容易に切断され、分離部２２が収納部１０から分離する。このとき、分離前の分離部２２は、延設部２０と一体に連結しており、開封前の包装容器１の携帯性が低下することを防止できる。 Further, the container portion 40 is arranged between the extending portion 20 and the separating portion 22, and a cutting line 21 formed of a non-penetrating notch cut at a predetermined depth in the thickness direction is formed. As a result, the container portion 40 is easily cut along the cutting line 21, and the separation portion 22 is separated from the storage portion 10. At this time, the separation portion 22 before separation is integrally connected to the extension portion 20, and it is possible to prevent the portability of the packaging container 1 before opening from being lowered.

また、熱接着部３１は、分離部２２側に突出する突出部３１ａを有し、突出部３１ａは複数並設される。これにより、分離部２２と収納部１０とを近づけたときに、突出部３１ａの先端上の蓋部３０に最初に剥離する力が加わる。これにより、蓋部３０を突出部３１ａ上から容易に剥離することができる。また、突出部を複数並設することにより、突出部３１ａが並ぶ方向（短手方向Ｘ）に直交する方向（長手方向Ｙ）に蓋部３０を容易に剥離することができる。 Further, the heat-bonding portion 31 has a protruding portion 31a protruding toward the separating portion 22, and a plurality of protruding portions 31a are arranged side by side. As a result, when the separating portion 22 and the accommodating portion 10 are brought close to each other, a force for first peeling is applied to the lid portion 30 on the tip of the protruding portion 31a. As a result, the lid portion 30 can be easily peeled off from the protrusion portion 31a. Further, by arranging a plurality of protruding portions side by side, the lid portion 30 can be easily peeled off in the direction (longitudinal direction Y) orthogonal to the direction in which the protruding portions 31a are lined up (short direction X).

また、延設部２０は、蓋部３０の反対方向に突出する凸部２３を有する。凸部２３は、収納部１０を挟んで分離部２２と対向する位置に配置される。また、凸部２３は、上面視において分離部２２側に凸の曲線状に形成される。これにより、手指（例えば、中指Ｆ３）を凸部２３の形状に沿って当接させて凸部２３を安定して支持できる。また、凸部２３を分離部２２側に強い力で押圧することができる。 Further, the extending portion 20 has a convex portion 23 projecting in the opposite direction of the lid portion 30. The convex portion 23 is arranged at a position facing the separating portion 22 with the accommodating portion 10 interposed therebetween. Further, the convex portion 23 is formed in a curved shape that is convex toward the separation portion 22 side in the top view. As a result, the fingers (for example, the middle finger F3) can be brought into contact with each other along the shape of the convex portion 23 to stably support the convex portion 23. Further, the convex portion 23 can be pressed against the separation portion 22 side with a strong force.

また、分離部２２は、蓋部３０の反対方向に突出する突起部２２ａを有する。突起部２２ａを設けることにより、分離部２２の厚みが大きくなり、分離部２２を強い力で摘持することができる。また、突起部２２ａによって分離部２２に凹凸が形成され、突起部２２ａを摘持する際に手指を滑り止めすることができる。 Further, the separating portion 22 has a protruding portion 22a protruding in the opposite direction of the lid portion 30. By providing the protruding portion 22a, the thickness of the separating portion 22 is increased, and the separating portion 22 can be gripped with a strong force. In addition, the protrusions 22a form irregularities on the separation portion 22, so that the fingers can be prevented from slipping when the protrusions 22a are gripped.

また、包装容器１の使用方法であって、分離部２２を手指で支持して蓋部３０を分離部２２とともに延設部２０から剥離させて収納部１０を開封する。具体的には、中指Ｆ３で凸部２３を支持しながら、分離部２２を親指Ｆ１と人差し指Ｆ２で摘持して凸部２３側に引っ張る。これにより、片手で収納部１０を開封することができ、包装容器１の開封時の利便性を向上できる。 Further, in the method of using the packaging container 1, the separation portion 22 is supported by fingers, the lid portion 30 is peeled off from the extension portion 20 together with the separation portion 22, and the storage portion 10 is opened. Specifically, while supporting the convex portion 23 with the middle finger F3, the separated portion 22 is grasped by the thumb F1 and the index finger F2 and pulled toward the convex portion 23 side. As a result, the storage unit 10 can be opened with one hand, and the convenience at the time of opening the packaging container 1 can be improved.

また、図９は包装容器１の変形例の側面断面を示している。図９に示すように凸部２３（図３参照）を省いてもよい。この場合、開封時、中指Ｆ３で収納部１０の分離部２２と反対側の側面を支持しながら、分離部２２を親指Ｆ１と人差し指Ｆ２で摘持して収納部１０側に引っ張る。これにより、片手で収納部１０を開封することができる。また、凸部２３を省くことにより、包装容器１を小型化できる。 Further, FIG. 9 shows a side cross section of a modified example of the packaging container 1. As shown in FIG. 9, the convex portion 23 (see FIG. 3) may be omitted. In this case, at the time of opening, the middle finger F3 supports the side surface of the storage portion 10 opposite to the separation portion 22, and the separation portion 22 is grasped by the thumb F1 and the index finger F2 and pulled toward the storage portion 10. As a result, the storage unit 10 can be opened with one hand. Further, by omitting the convex portion 23, the packaging container 1 can be miniaturized.
