Description

本発明は、容器に関し、特に容器本体と蓋体との嵌合性能を高めつつも簡単に蓋体を取り外すことができる容器に関する。   The present invention relates to a container, and more particularly to a container in which a lid can be easily removed while enhancing the fitting performance between the container body and the lid.

例えば、惣菜や弁当等の食品、その他の加工食品類を収容する包装用容器においては、ともに合成樹脂シート製の容器本体に蓋体を重ね合わせた形態が一般的である。この場合、容器本体と蓋体とは単純に重ね合わされているに過ぎないため、双方の分離を防ぐ必要がある。そこで、惣菜等が容器本体に詰め合わされた後、蓋体が被せられ、蓋体と容器本体がテープやシール等により複数箇所封止される。主にテープ類の封止による容器の場合、容器本体と蓋体との互いの密着量が少ない箇所が現れるため、内容物の乾燥や漏出等のおそれがある。このようなことから、専ら短時間での販売用途としての利用が多い。   For example, in packaging containers that contain foods such as sugar beets and lunch boxes, and other processed foods, a form in which a lid is superimposed on a container body made of a synthetic resin sheet is generally used. In this case, since the container main body and the lid are simply overlapped, it is necessary to prevent separation of both. Therefore, after the side dish or the like is packed in the container body, the lid body is put on, and the lid body and the container body are sealed at a plurality of locations by tape, seals, or the like. In the case of a container mainly sealed with tapes, a portion where the amount of close contact between the container body and the lid appears is small, and there is a risk of the contents being dried or leaked. For this reason, it is often used exclusively for sales in a short time.

この点に留意して、容器本体と蓋体の分離を完全に防止し、しかも内容物の乾燥や漏出を極力抑制するため、容器本体に蓋体を重ね合わせた後にラップフィルムで双方を完全に被覆する手法が増えつつある。特に、コンビニエンスストア等で販売される弁当類に多く見られる。事後的にラップフィルムで被覆されるため、前記のテープ類を用いた封止に比べて衝撃に強く、取り扱い時の利便性は大きく高まった。   With this in mind, in order to completely prevent the container body and lid from separating and to suppress the drying and leakage of the contents as much as possible, both sides are completely covered with a wrap film after the lid is overlaid on the container body. There are an increasing number of coating methods. In particular, it is often found in lunch boxes sold at convenience stores. Since it was later covered with a wrap film, it was more resistant to impact than the sealing using the tapes described above, and the convenience during handling was greatly increased.

上記に加え、いったん封止した後の容器本体と蓋体の分離を回避するべく、蓋体の形状に工夫を凝らした容器が多く提案されている(例えば、特許文献1、2等参照)。前記の特許文献等の容器にあっては、容器本体の開口部に形成された縁部(フランジ部)の外側から蓋体側の縁部(フランジ部、スカート部)が被さり嵌合される構造が多く見られる。このように、蓋体による外嵌構造を採用することにより、容器本体と蓋体との嵌合性能は高まった。しかしながら、依然として容器本体に蓋体が重ね合わされた後にラップフィルムで双方は被覆されている。なぜならば、容器本体と蓋体との嵌合性能は高まったとしても、搬送、陳列時の振動、衝撃を勘案すると、嵌合の強度は十分ではなかった。   In addition to the above, many containers have been proposed in which the shape of the lid is devised in order to avoid separation of the container body and the lid once sealed (see, for example, Patent Documents 1 and 2). In the container of the above-mentioned patent document etc., there is a structure in which the edge part (flange part, skirt part) on the lid side is covered and fitted from the outside of the edge part (flange part) formed in the opening of the container body. Many are seen. Thus, the fitting performance of a container main body and a cover body improved by employ | adopting the external fitting structure by a cover body. However, both are still covered with a wrap film after the lid is superimposed on the container body. This is because even if the fitting performance between the container main body and the lid is improved, the strength of fitting is not sufficient in consideration of vibration and impact during transportation and display.

現状、陳列販売される惣菜や弁当類の容器は封止後ラップフィルムにより全体が被覆されている。これには、前述のとおり、搬送、陳列時の振動、衝撃に耐性を持たせて安易に蓋体が外れなくすることに加え、容器外部から容器本体と蓋体の隙間を通じて異物が混入される被害を防止する意味もある。いったんラップフィルムを容器から剥がした後は元の被覆状態に戻せないため、不正行為に対する防御手段として有効であるためである。   At present, prepared and sold food containers and lunch boxes are entirely covered with a wrap film after sealing. As described above, in addition to preventing the lid from easily coming off by being resistant to vibration and shock during transportation and display, foreign substances are mixed from outside the container through the gap between the container body and the lid. It also has the meaning of preventing damage. This is because once the wrap film is peeled off from the container, it cannot be returned to its original covering state, and is effective as a defense against fraud.

近年、ラップフィルムによる容器の包装形態に対しても、環境問題の見地から省資源化が求められている。そこで、内容物の包装に不可欠な容器のみに集約してラップフィルムによる被覆包装の省略が検討されてきた。ところが、ラップフィルムによる被覆包装を省略しようとする場合、分離回避や不正防止の点において従前の容器本体と蓋体との嵌合性能では不十分であった。そのため、前出の特許文献1、2等に開示の蓋体を採用した場合、蓋体側の縁部(フランジ部、スカート部)の長さ等を調節する必要があり、否応なく喫食時の蓋体が開封しづらかった。   In recent years, resource saving has also been demanded from the viewpoint of environmental problems for packaging forms of containers using wrap films. Therefore, it has been studied to omit the covering and wrapping with the wrap film by concentrating only on the containers indispensable for packaging the contents. However, when trying to omit the covering and wrapping with the wrap film, the conventional fitting performance between the container body and the lid is insufficient in terms of avoiding separation and preventing fraud. Therefore, when the lid disclosed in the above-mentioned Patent Documents 1 and 2, etc. is adopted, it is necessary to adjust the length of the edge (flange portion, skirt portion) on the lid side, and the lid at the time of eating is inevitably My body was hard to open.

請求項1をはじめとする発明に規定する容器1は、図1の全体斜視図に図示のとおり、容器本体10とこの上部に被せられて嵌合する蓋体30を備える。図示では、一般的な弁当、惣菜等の包装用途としているため、容器本体10及び蓋体30はともに平面視で長方形状である。以降の実施例では多角形状として平面視で四角形の容器を例に図示し、説明する。なお、多角形状とは角部分が辺同士により接合されている形態に加え、辺同士の接合部分が湾曲状に面取りされた形態も含まれる。   The container 1 prescribed | regulated to invention including Claim 1 is equipped with the cover body 30 which covers and fits the container main body 10 and this upper part, as shown in the whole perspective view of FIG. In the figure, since the packaging is used for general lunch boxes and prepared dishes, the container body 10 and the lid body 30 are both rectangular in plan view. In the following embodiments, a polygonal container is illustrated and described as an example of a rectangular container in plan view. The polygonal shape includes not only a form in which corner portions are joined by sides but also a form in which a joined portion between sides is chamfered in a curved shape.

この実施例の容器本体10及び蓋体30は、ポリエチレン、ポリプロピレン、ポリスチレン、ポリエチレンテレフタレート等の熱可塑性樹脂のシート(合成樹脂シート)、さらにはポリ乳酸等の生分解性樹脂の熱可塑性樹脂のシートから形成される。前記の合成樹脂シートは真空成形により図示をはじめとする各種形状に成形される。合成樹脂シートの厚さは適宜ではあるものの、概ね1mm以下の厚さである。容器本体と蓋体の組み合わせにおいて、合成樹脂シートの原料樹脂を同一種類としても異なる種類としてもよい。樹脂の種類は用途、内容物、包装対象により適宜選択される。なお、容器本体10または蓋体30のいずれかもしくは両方を紙やその他の可撓性素材から製造することもできる。   The container body 10 and the lid body 30 of this embodiment are made of a thermoplastic resin sheet (synthetic resin sheet) such as polyethylene, polypropylene, polystyrene, and polyethylene terephthalate, and further a biodegradable thermoplastic resin sheet such as polylactic acid. Formed from. The synthetic resin sheet is formed into various shapes such as illustrated by vacuum forming. Although the thickness of the synthetic resin sheet is appropriate, it is approximately 1 mm or less. In the combination of the container main body and the lid, the raw resin of the synthetic resin sheet may be the same or different. The type of resin is appropriately selected depending on the application, contents, and packaging target. Note that either or both of the container main body 10 and the lid 30 can be manufactured from paper or other flexible materials.

容器本体10について図1とともに図2の部分拡大斜視図も加えて説明する。容器本体10は、その上面11が開口して開口縁部12が形成される。この開口縁部12に当該開口縁部から容器本体外部側に折り返される折り曲げ壁部13が形成される。そして、開口縁部12の容器本体内部側は内周壁部17となる。容器本体10では、上面11の直下に容器壁部15と容器底部16が配されて容器本体内部14が形成され、容器構造となっている。図示では容器本体10を単一の容器本体内部14としている。これに代えて、容器本体内部を区画する仕切り部(図示せず)を容器壁部と容器底部に備えることもできる。図示の容器本体10は平面視で長方形形状であることから、容器角部18と容器辺部19の組み合わせとなる。図中、符号20は操作部、21はつまみ部、25は可撓帯部である。   The container body 10 will be described with reference to FIG. As for the container main body 10, the upper surface 11 opens and the opening edge part 12 is formed. A bent wall portion 13 is formed on the opening edge portion 12 so as to be folded back from the opening edge portion to the container body outer side. And the container main body inside side of the opening edge part 12 becomes the inner peripheral wall part 17. In the container main body 10, a container wall 15 and a container bottom 16 are arranged immediately below the upper surface 11 to form a container main body interior 14, thereby forming a container structure. In the figure, the container body 10 is a single container body interior 14. It can replace with this and the partition part (not shown) which divides the inside of a container main body can also be provided in a container wall part and a container bottom part. Since the illustrated container body 10 has a rectangular shape in plan view, it is a combination of the container corner 18 and the container side 19. In the figure, reference numeral 20 denotes an operation part, 21 denotes a knob part, and 25 denotes a flexible belt part.

蓋体30について図1とともに図3の部分拡大斜視図も加えて説明する。蓋体30は容器本体10と開閉可能であり、当該蓋体30の外周全体に包着部31が形成される。蓋体30が容器本体10に対して閉鎖状態(被さった状態)において、容器本体10の開口縁部12及び折り曲げ壁部13は、蓋体30の包着部31により外側から包み込まれて包着される。そして、蓋体30の包着部31には、開口縁部12と当接する接縁部32が設けられ、さらに接縁部32の外側にスカート部33が形成される。容器本体10が平面視で長方形形状であることから、これに対応する蓋体30も長方形形状であり、蓋体角部38と蓋体辺部39の組み合わせとなる。蓋体30の上面は蓋面部37であり、その周囲に蓋周壁部36となる。図中、符号42は内嵌溝部、43は外嵌溝部である。   The lid 30 will be described with reference to FIG. The lid body 30 can be opened and closed with the container body 10, and the covering portion 31 is formed on the entire outer periphery of the lid body 30. In the closed state (covered state) of the lid body 30 with respect to the container body 10, the opening edge portion 12 and the bent wall portion 13 of the container body 10 are wrapped by the wrapping portion 31 of the lid body 30 from the outside. Is done. The wrapping portion 31 of the lid 30 is provided with a contact edge portion 32 that comes into contact with the opening edge portion 12, and a skirt portion 33 is formed outside the contact edge portion 32. Since the container body 10 has a rectangular shape in plan view, the corresponding lid body 30 is also in a rectangular shape, which is a combination of the lid corner portion 38 and the lid side portion 39. The upper surface of the lid body 30 is a lid surface portion 37, and the lid peripheral wall portion 36 is formed around the lid surface portion 37. In the figure, reference numeral 42 denotes an inner fitting groove, and 43 denotes an outer fitting groove.

この実施例では、既存の容器本体と蓋体の組み合わせより構成される容器よりも、容器本体と蓋体との嵌合による組み合わせ構造の精度がより高められている。当該構造は、図4の蓋体の部分拡大平面図並びに図5の容器の辺部及び角部における断面図に開示され、請求項2の発明として規定される。   In this embodiment, the accuracy of the combined structure by the fitting of the container body and the lid is further improved than the container constituted by the combination of the existing container body and the lid. The structure is disclosed in the partially enlarged plan view of the lid body of FIG. 4 and the cross-sectional views of the side portion and the corner portion of the container of FIG. 5 and is defined as the invention of claim 2.

すなわち、蓋体30の包着部31の接縁部32には、容器本体10の開口縁部12に対してその内側から嵌合(内嵌)する内嵌溝部42が形成される。開口縁部12の内側の内周壁部17は、内嵌溝部42の溝側壁44による接触となる(図5(a)参照)。また、蓋体30の包着部31のスカート部33には、容器本体10の折り曲げ壁部13に対してその外側から嵌合(外嵌)する外嵌溝部43が形成される。図示では容器角部18に位置する折り曲げ壁部13は、その部分において外嵌溝部43の凹壁部45による接触となる(図5(b)参照)。そして、内嵌溝部42及び外嵌溝部43は、蓋体30の包着部31において互いに連接した配置として形成される。図示から把握されるように、内嵌溝部42と外嵌溝部43は、互い違いに連続させて、双方を接近させた配置である。   That is, an inner fitting groove portion 42 that fits (internally fits) from the inside to the opening edge portion 12 of the container body 10 is formed at the contact edge portion 32 of the covering portion 31 of the lid 30. The inner peripheral wall 17 inside the opening edge 12 is brought into contact with the groove side wall 44 of the inner fitting groove 42 (see FIG. 5A). In addition, an outer fitting groove 43 is formed in the skirt portion 33 of the covering portion 31 of the lid 30 so as to be fitted (externally fitted) from the outside to the bent wall portion 13 of the container body 10. In the drawing, the bent wall portion 13 located at the container corner portion 18 is in contact with the concave wall portion 45 of the external fitting groove portion 43 at that portion (see FIG. 5B). And the inner fitting groove part 42 and the outer fitting groove part 43 are formed as arrangement | positioning mutually connected in the attachment part 31 of the cover body 30. As shown in FIG. As can be seen from the drawing, the inner fitting groove portions 42 and the outer fitting groove portions 43 are arranged in such a manner that they are alternately continued and close to each other.

内嵌溝部42と外嵌溝部43は互いに連接する配置となるため、蓋体30の蓋体辺部39側に形成された内嵌溝部42により、容器本体10の開口縁部12の容器辺部19側の密着性が高められる。同時に、蓋体30の蓋体角部38側に形成された外嵌溝部43により、容器本体10の開口縁部12の容器角部18側の密着性が高められる。特に、図示実施例の蓋体30の内嵌溝部42と外嵌溝部43は、従前の容器における嵌合用の溝部よりもより溝深さを大きく形成している。このことから、容器本体と蓋体のみであっても双方の嵌合性能が高められ、簡単には開封されない。さらに、容器本体10の開口縁部12の全周囲(図示の容器角部18と容器辺部19)は、ほとんど隙間なく蓋体30の包着部31により包着されることから、容器本体10の開口縁部12の封止精度が向上し、異物混入等の不正行為に対応することができる。ゆえに、ラップフィルムによる被覆包装の省略が可能となる。   Since the inner fitting groove portion 42 and the outer fitting groove portion 43 are arranged to be connected to each other, the container side portion of the opening edge portion 12 of the container body 10 is formed by the inner fitting groove portion 42 formed on the lid body side portion 39 side of the lid body 30. The adhesion on the 19th side is improved. At the same time, the outer fitting groove 43 formed on the lid body corner portion 38 side of the lid body 30 improves the adhesion of the opening edge portion 12 of the container body 10 on the container corner portion 18 side. In particular, the inner fitting groove portion 42 and the outer fitting groove portion 43 of the lid body 30 of the illustrated embodiment are formed to have a larger groove depth than the fitting groove portion in the conventional container. From this, even if it is only a container main body and a cover body, both fitting performance is improved and it is not opened easily. Furthermore, the entire periphery of the opening edge 12 of the container body 10 (the container corner 18 and the container side 19 shown in the figure) is wrapped by the wrapping portion 31 of the lid 30 with almost no gap. Thus, the sealing accuracy of the opening edge 12 can be improved, and it is possible to cope with fraudulent acts such as mixing of foreign substances. Therefore, it is possible to omit the covering and wrapping with the wrap film.

図4、図5等に開示の実施例において、容器本体と蓋体との間の強固な嵌合を得るためには、図5等に開示のとおり、蓋体30の包着部31に十分な深さを備えた外嵌溝部43を形成する必要がある。そのため、容器本体10の折り曲げ壁部13の高さ、真空成形による合成樹脂シートからの加工、成形し易さ等から、必然的に蓋体30(包着部31)の周囲に垂下するスカート部33も長くなる。そうすると、前述の容器本体10と蓋体30との強固な嵌合と引き換えに、容器において蓋体の開封し難くなる。   In the embodiment disclosed in FIGS. 4, 5, etc., in order to obtain a strong fit between the container body and the lid, as shown in FIG. It is necessary to form the external fitting groove 43 having a sufficient depth. Therefore, the skirt part that inevitably hangs around the lid 30 (the covering part 31) due to the height of the bent wall part 13 of the container body 10, the processing from the synthetic resin sheet by vacuum forming, the ease of forming, and the like. 33 also becomes longer. If it does so, it will become difficult to open a cover body in a container in exchange for the firm fitting with the above-mentioned container main body 10 and the cover body 30. FIG.

そこで、上記の問題点の両立を図るため、図1、図2、及び図6の操作部における断面図に開示する操作部20が役立つ。操作部20は容器本体10の折り曲げ壁部13に備えられる。図示するように、操作部20は容器本体10と一体に合成樹脂シートから形成される。操作部20の形状については特段制約されることはなく、次に述べる操作が可能である限り適宜形状が採用される。その上で、請求項3の発明に規定するように、操作部20の先端21側が膨大してつまみ部22が形成される。   Therefore, the operation unit 20 disclosed in the cross-sectional views of the operation unit in FIGS. 1, 2, and 6 is useful in order to satisfy both of the above problems. The operation unit 20 is provided on the bending wall portion 13 of the container body 10. As shown in the figure, the operation unit 20 is formed of a synthetic resin sheet integrally with the container body 10. The shape of the operation unit 20 is not particularly limited, and a shape is appropriately adopted as long as the operation described below is possible. In addition, as defined in the invention of claim 3, the tip portion 21 side of the operation portion 20 is enormous and the knob portion 22 is formed.

実施例のつまみ部22は指先が入る程度の中空の半球状としている。このつまみ部22の裏側22bに指を入れることができるため、つまみ部22は表裏から挟まれ操作部20の操作時に滑りにくく、円滑な操作が可能となる。操作部20において、つまみ部22は可撓帯部25により容器本体10の折り曲げ壁部13に接続される。可撓帯部25の幅や長さは特に限定されず、操作部20の可撓性や強度に影響を与えず、かつ、スカート部33(その下端34)に接触可能な範囲で選択される。   The knob portion 22 of the embodiment has a hollow hemispherical shape that allows a fingertip to enter. Since a finger can be put into the back side 22b of the knob part 22, the knob part 22 is sandwiched from the front and back and is not slippery when the operation part 20 is operated, and smooth operation is possible. In the operation part 20, the knob part 22 is connected to the bent wall part 13 of the container body 10 by a flexible band part 25. The width and length of the flexible belt portion 25 are not particularly limited, and are selected within a range that does not affect the flexibility and strength of the operation portion 20 and can contact the skirt portion 33 (the lower end 34 thereof). .

まず、図6(a)は、蓋体30が容器本体10に被せられて嵌合により包着した容器1の封止の状態である。この時点では操作部20は何ら操作されることなく折り曲げ壁部13から垂下したままである。なお、製品の完成に伴う蓋体の封止を証明するための認証シール等をスカート部33に可撓帯部25を重ねるようにして貼付することもできる。   First, FIG. 6A shows a sealed state of the container 1 in which the lid body 30 is put on the container body 10 and wrapped by fitting. At this time, the operation unit 20 remains suspended from the bent wall 13 without any operation. Note that an authentication seal or the like for certifying the sealing of the lid accompanying the completion of the product can be attached to the skirt portion 33 so that the flexible band portion 25 is overlapped.

次に図6(b)では、つまみ部22を指で摘みながら操作部20を上方に持ち上げている状態である(矢印L参照)。この場合、操作部20の可撓帯部25がスカート部33に接触して、スカート部33の下端34は操作部20の可撓帯部25からの押圧を受けてまくり上げられる。そして、蓋体30側の外嵌溝部43が容器本体10の開口縁部12のスカート部33(容器角部18)から離れる(矢印F1参照)。   Next, in FIG.6 (b), it is the state which lifted the operation part 20 upwards, picking the knob part 22 with a finger (refer arrow L). In this case, the flexible band portion 25 of the operation unit 20 comes into contact with the skirt portion 33, and the lower end 34 of the skirt portion 33 is rolled up by receiving a pressure from the flexible band portion 25 of the operation unit 20. And the external fitting groove part 43 by the side of the cover body 30 leaves | separates from the skirt part 33 (container corner part 18) of the opening edge part 12 of the container main body 10 (refer arrow F1).

操作部20の操作が蓋体30に及ぼす影響について、図7の全体平面図も含めて説明する。実施例として図示し、請求項4の発明に規定するように、容器本体10及び蓋体30は平面視で四角形状(多角形状)であり、操作部20は当該容器本体10の容器角部18に位置し形成されている。そこで、操作部20(つまみ部22)のつまみ上げ(矢印L参照)の操作と、これに起因する可撓帯部25による蓋体30のスカート部33のまくり上げ(矢印F1参照)を介して、当該操作部に近接した位置の蓋体30の嵌合が解除される。これに伴い、蓋体30の一角(蓋体角部38のひとつ)のスカート部33に歪み変形が生じるとともに、変形した蓋体角部38の左右両辺の蓋体辺部39にも歪み変形が連続的に伝播される(矢印F2参照)。つまり、片手で一回のワンタッチ操作が可能である。   The influence of the operation of the operation unit 20 on the lid 30 will be described including the overall plan view of FIG. As shown in the embodiment and defined in the invention of claim 4, the container body 10 and the lid body 30 have a quadrangular shape (polygonal shape) in plan view, and the operation unit 20 has the container corner 18 of the container body 10. Is located and formed. Therefore, through the operation of raising the operation unit 20 (knob unit 22) (see arrow L) and the rolling up of the skirt 33 of the lid 30 by the flexible band 25 resulting from this (see arrow F1). The fitting of the lid 30 at a position close to the operation unit is released. Along with this, distortion deformation occurs in the skirt portion 33 at one corner of the lid 30 (one of the lid corner portions 38), and distortion deformation also occurs in the lid side portions 39 on both the left and right sides of the deformed lid corner portion 38. Propagated continuously (see arrow F2). That is, one-touch operation can be performed once with one hand.

多角形状とする容器の形状を採用する場合、操作部を角部に設けることにより、一回の操作によって蓋体に変形を生じさせる量が多くなり効率が良い。結果、実施例の蓋体30のように、内嵌溝部42及び外嵌溝部43を備えて嵌合性能を高めた構造を採用した場合であっても、蓋体30の容器本体10からの取り外し易さを確保することができる。   In the case of adopting a polygonal container shape, providing the operation portion at the corner portion increases the amount of deformation of the lid body by a single operation, which is efficient. As a result, even when the structure with the inner fitting groove 42 and the outer fitting groove 43 43 and having improved fitting performance is employed as in the lid body 30 of the embodiment, the lid body 30 is detached from the container body 10. Ease of use can be ensured.

図8は本発明の他の実施例に係る容器2の全体斜視図である。この実施例の容器2は、これまでに図示し詳述した平面視で四角形の容器と異なり、円錐台(円筒も含む)のように、角部と辺部の区別のない形態である。容器2では容器本体10Aに蓋体30Aが組み合わされる。容器本体10Aの上面11、開口縁部12、及び折り曲げ壁部13等の構成は、角部と辺部の区別がない以外は前掲の実施例と同様である。蓋体30Aには包着部31、接縁部32、スカート部33、内嵌溝部42a、及び外嵌溝部43a等が形成され、角部と辺部の区別がない構造である。前出の図1等の実施例と共通する部位には同一符号を付し、説明を省略する。   FIG. 8 is an overall perspective view of the container 2 according to another embodiment of the present invention. Unlike the rectangular container in plan view shown and described in detail, the container 2 of this embodiment has a shape with no distinction between corners and sides like a truncated cone (including a cylinder). In the container 2, the lid body 30A is combined with the container body 10A. The configuration of the upper surface 11, the opening edge portion 12, the bent wall portion 13 and the like of the container main body 10A is the same as that of the above-described embodiment except that there is no distinction between corner portions and side portions. The lid 30A is formed with an attachment portion 31, an edge portion 32, a skirt portion 33, an inner fitting groove portion 42a, an outer fitting groove portion 43a, and the like, so that there is no distinction between corner portions and side portions. The same reference numerals are given to portions common to the embodiment of FIG.

この実施例の蓋体30Aの内嵌溝部42aは、包着部31の内側に全周にわたって形成され、外嵌溝部43aは2箇所形成される。図示から把握されるように、内嵌溝部42a及び外嵌溝部43aは互いに連接した配置である。むろん、内嵌溝部42aを包着部31の内側全周とする以外にも、半円弧状に2箇所のように途切れさせる配置も可能である。そして、途切れた内嵌溝部42aの間に外嵌溝部43aを配置することもできる(いずれも図示省略)。   The inner fitting groove part 42a of the lid body 30A of this embodiment is formed over the entire circumference inside the covering part 31, and two outer fitting groove parts 43a are formed. As can be understood from the drawing, the inner fitting groove 42a and the outer fitting groove 43a are arranged to be connected to each other. Of course, in addition to the inner fitting groove portion 42a being the entire inner circumference of the enveloping portion 31, it is also possible to dispose the inner fitting groove portion 42a in two semicircular arcs. And the outer fitting groove part 43a can also be arrange | positioned between the interrupted inner fitting groove parts 42a (all are abbreviate | omitting illustration).

容器本体10Aに蓋体30Aを被せる場合、位置の指定はないものの、操作部20Aの操作による蓋体30Aの開封し易さを考慮して、操作部20Aに外嵌溝部43aが重ねられる。図8の容器2の操作部20Aでは、操作部20Aの先端21側につまみ部の代わりに操作環部23が形成される。操作部20Aの使用に際し、指を環部23に入れて引っ張り上げることができる。この場合、操作部20Aの操作に伴い蓋体30Aのスカート部33は可撓帯部25と接触して押圧を受ける。そこで、外嵌溝部43a容器本体10Aの開口縁部12のスカート部33から離れる。結果、操作部20A付近の蓋体30Aの歪みにより、蓋体30Aと容器本体10Aの嵌合に隙間が生じ、蓋体30Aを外しやすくすることができる。   When covering the container main body 10A with the lid 30A, the position is not specified, but the external fitting groove 43a is overlapped with the operation portion 20A in consideration of easy opening of the lid 30A by the operation of the operation portion 20A. In the operation portion 20A of the container 2 in FIG. 8, an operation ring portion 23 is formed on the tip 21 side of the operation portion 20A instead of the knob portion. When using the operation unit 20 </ b> A, a finger can be put into the ring unit 23 and pulled up. In this case, the skirt portion 33 of the lid body 30A comes into contact with the flexible belt portion 25 and receives a pressure as the operation portion 20A is operated. Therefore, the outer fitting groove 43a is separated from the skirt 33 of the opening edge 12 of the container body 10A. As a result, due to the distortion of the lid 30A near the operation unit 20A, a gap is generated in the fitting between the lid 30A and the container main body 10A, and the lid 30A can be easily removed.

これまでに図示し、詳述した実施例の容器における容器本体及び蓋体の構造を適用することにより、双方間に強力な嵌合性能が得られるとともに、封止精度が向上して異物混入等にも対応することができる。さらには、封止の解除に際し、操作部を備えることから片手による操作で簡単に容器本体から蓋体を取り外すことができる。そこで、ラップフィルムによる被覆包装の省略が可能となり包装資材の省資源化が可能となるとともに、包装容器としてのバリアフリー化に叶う。このことから、蓋体の開封し易さを実現しつつ、他商品との差別化、購入者や販売者への訴求性につながる容器や蓋体の提案が可能である。特に、ラップフィルムの被覆包装は専用の機器を用いるため、ラップフィルムの包装が省略できれば、設備投資負担も軽減され、省資源化のみならず経費節減にも貢献できる。   By applying the structure of the container main body and the lid in the container of the embodiment shown and described in detail so far, a strong fitting performance can be obtained between the two, and the sealing accuracy is improved and foreign matters are mixed in. Can also respond. Furthermore, since the operation part is provided when the sealing is released, the lid can be easily removed from the container body by one-handed operation. Therefore, it is possible to omit the covering and wrapping with the wrap film, and it is possible to save resources of the packaging material, and to achieve barrier-free as a packaging container. From this, it is possible to propose containers and lids that realize ease of opening the lid, differentiate from other products, and appeal to buyers and sellers. In particular, since the wrapping film packaging uses dedicated equipment, if the wrapping film packaging can be omitted, the equipment investment burden can be reduced, which can contribute not only to resource saving but also to cost saving.

なお、本発明の容器における容器本体及び蓋体の大きさ、形状、さらには内嵌溝部、外嵌溝部の大きさ、数量等は、容器の使用目的、用途、内容物を勘案して最適に選択される。このため、図示し詳述した実施例の構成のみには限定されない。   The size and shape of the container main body and lid in the container of the present invention, as well as the size, quantity, etc. of the inner fitting groove and outer fitting groove are optimal in consideration of the purpose, application, and contents of the container. Selected. For this reason, it is not limited only to the structure of the Example shown and explained in full detail.
