Description

【0001】
【発明の属する技術分野】
本発明は、菓子等の食品や薬品、日用品等の種々の被包装物を収容する包装容器に関する。
【0002】
【従来の技術】
従来、この種の包装容器としては、被包装物を収容する容器本体と、該容器本体の開口部を閉塞する蓋体とを備え、該蓋体は、固定部と、蓋体を横断するヒンジ部で固定部と区分され且つ該ヒンジ部を起点として開閉可能な可動部とを備えているものが公知である。そして、固定部及び可動部には各々容器本体の開口部と嵌合する嵌合部が設けられ、固定部はその嵌合部で容器本体に固定され、可動部は嵌合部が容器本体に嵌合することでその閉状態が維持される構成となっている。
【0003】
かかる包装容器では、可動部の開閉動作によって、開口部のうちの所定領域のみを自在に開閉できるうえに、しかも、可動部に嵌合部が設けられているため、繰り返して開口部を閉塞することができるという利点がある。
【0004】
【発明が解決しようとする課題】
しかるに、該包装容器にあっては、嵌合部の嵌合のみで蓋体の容器本体への装着状態が維持される構成であるため、開口部が蓋体で密封されず、密封性を要求する被包装物の収容には適さない。
【0005】
そこで本発明は、上記従来の問題点に鑑みてなされ、被包装物を密封包装することができ、しかも、開封後における蓋体の繰り返しの開閉性にも優れる包装容器を提供することを課題とする。
【0006】
【課題を解決するための手段】
本発明は、上記課題を解決すべくなされたものであり、本発明に係る包装容器は、容器本体1の開口部を閉塞する蓋体2が設けられ、該蓋体2は、開口部の所定領域を開閉できるように、容器本体1に固定された固定部2bと、蓋体2を横断するヒンジ部5で固定部2bと区分され且つ該ヒンジ部5を起点として開閉可能な可動部2aとを備えると共に、容器本体1の開口縁部にヒートシールにより接着されて開口部を密封し、可動部2aは、開口縁部に剥離可能にヒートシールされると共に、可動部2a及び固定部2bの裏面側に設けられる凸部7,7が容器本体1の開口部の内側に嵌合することによりその閉状態が維持されるよう構成されている包装容器において、蓋体2全体が容器本体1から取り外し可能とすべく、固定部2bも開口縁部に剥離可能にヒートシールされる一方、蓋体2が可動部2a側から剥離された際に固定部2b側への剥離の進行を停止させるべく、固定部2bのヒンジ部5近傍には、他の部分よりも強く接着された強接着部9が設けられ、蓋体2は、可動部2aの開状態が維持されるべく、可動部2a側に、嵌合凸部10を備えると共に、固定部2b側に、可動部2aの開状態で嵌合凸部10に嵌入される嵌合凹部11を備え、嵌合凹部11は、固定部2bの凸部7に対応して形成される表面側の凹部4であることを特徴とする。
【0007】
該包装容器にあっては、蓋体2が容器本体1の開口縁部にヒートシールにより接着されているので、開封前における開口部の密封性が確保される。そして、可動部2aが剥離可能にヒートシールされているので、該可動部2aをヒンジ部5まで剥離して開封することができる。また、固定部2bがヒートシールにより容器本体1に接着されているため、開封後において可動部2aをスムーズに開閉することができ、可動部2aを容器本体1に嵌合させて所定領域を閉じることができる。
【0008】
、固定部2bも剥離可能にヒートシールしておくと、例えば、被包装物の取り出し完了後において蓋体2全体を容器本体1から取り外すことができる。
【0009】
このように、固定部2bのヒンジ部5近傍に他の部分よりも開口縁部と強く接着された強接着部9を設けることにより、包装容器を開封する際に、ヒンジ部5まで可動部2aのみをより確実に且つ容易に剥離することができる。また、本発明に係る包装容器においては、蓋体2が可動部2a側から剥離された際に固定部2b側への剥離の進行を停止させるべく、ヒンジ部5の両端部に切込部を設けられていてもよい。尚、切込部は、切欠部も含む概念である。
【0011】
【発明の実施の形態】
以下、本発明の包装容器の一実施形態について図1乃至図3を参酌しつつ、被包装物を収容すべく上面が開口した有底筒状の容器本体1と、該容器本体1の開口部を閉塞すべく容器本体1に装着された蓋体2とを備えた包装容器について説明する。
【0012】
容器本体1は、蓋体2とヒートシール可能なプラスチックシートから真空成形若しくは圧空成形により形成されている。該プラスチックシートとしては、例えば、ポリプロピレン系のプラスチックシートや、表面がポリプロピレン系樹脂で中間にエチレンビニルアルコール共重合体等のガスバリアー層を積層したシートが好ましいが、ポリエステル、ポリスチレンやポリエチレン等の単層や多層のプラスチックシートが使用できる。尚、ポリプロピレン系樹脂等の射出成形としてもよい。
そして、開口縁部には外側に向けてフランジ部3が周設され、該開口縁部に前記蓋体2がヒートシールにより接着されている。即ち、本実施形態ではフランジ部3の上面全周に蓋体2がヒートシールされることで容器本体1の開口部が密封状態となっている。
【0013】
かかる蓋体2は、プラスチックシートからシート成形により形成されたもので、該プラスチックシートは、シート成形可能な厚さ0.3mm乃至2.0mm程度の単層あるいは多層の種々のシートを採用でき、少なくとも、裏面側が容器本体1とヒートシール可能に構成されている。本実施形態では、ポリプロピレン系樹脂からなるシート基材に、ポリプロピレン系イージーピールシーラント層を積層した多層シートを採用しており、該イージーピールシーラント層(ヒートシール後に剥離可能あるいは破壊可能となるシーラント層)が裏面側となるように、シート成形によって表裏方向に凹凸が形成されて容器本体1のフランジ部3上面にヒートシールされる。
【0014】
該イージーピールシーラント層は、ポリプロピレン系樹脂にポリエチレン系樹脂やポリスチレン系樹脂等が含有された単層のものや、1乃至数μmの層間剥離可能な接着層を積層した多層のものであり、これにより、ポリプロピレン系樹脂単体のシーラント層と比較してシール力が低下し、ヒートシール後において剥離可能となる。即ち、蓋体2は容器本体1に剥離可能にヒートシールされている。
【0015】
また、この蓋体2は、平面視略円形状を呈し、シート成形によって表面側に開口する略半円状の凹部4,4が互いに対向して二箇所形成され、両凹部4,4の境界には蓋体2を横断するように表面側に凸のヒンジ部5が形成されている。即ち、該ヒンジ部5によって蓋体2は二分され、その一方は、容器の開封後においてヒンジ部5を起点として開閉可能となる可動部2aで、他方は可動部2aの開閉の際に容器本体1に対して固定状態となる固定部2bである。尚、可動部2aには、ヒンジ部5と反対側の位置に、外周から突設した開封用の摘み部6が形成されている。
【0016】
また、シート成形による両凹部4,4の形成に対応して、可動部2a側と固定部2b側の裏面側には各々凸部7,7が形成され、両凸部7,7の外周側の側面には、外側に僅かに突出した嵌合突出部7aが複数形成されている。該嵌合突出部7aが容器本体1の開口部の内側に嵌合する嵌合部である。尚、嵌合突出部7aを設けずに凸部7(外周側の側面)が直接開口部の内側に嵌合する構成としてもよい。
【0017】
更に、図1及び図3の如く、ヒンジ部5の両端部には各々切欠部8が形成されている。また、開口縁部にヒートシールされたシール部分のうち、固定部2b側のシール部分には、ヒンジ部5近傍位置に他の部分よりも強く接着された強接着部9(図1及び図3のクロスハッチ部分)が設けられている。該強接着部9は、前記切欠部8の固定部2b側近傍に設けられ、他のシール部分よりも相対的に高温高圧でヒートシールされている。
【0018】
尚、ヒンジ部5を境として、その可動部2a側には嵌合凸部10が、固定部2b側には嵌合凹部11が各々形成され、可動部2aをヒンジ部5を起点として上方に回動させて固定部2bの上方に重ね合わせた際に、嵌合凸部10が嵌合凹部11に嵌入して可動部2aの開状態が維持できる。尚、嵌合凸部10と嵌合凹部11はヒンジ部5に沿って所定間隔離間して一対設けられている。
【0019】
以上のように構成された包装容器にあっては、一枚のシートから容易に蓋体2を成形によって形成することができ、該蓋体2が容器本体1にヒートシールされているので開封前において開口部の密封状態を得られ、従って、高い密封性が要求される被包装物も完全密封包装することができる。
【0020】
しかも、蓋体2を剥離可能にヒートシールしているので、蓋体2を剥離することで容器を容易に開封することができる。その際、摘み部6を摘んで可動部2aを上方に向けて引っ張ると、摘み部6近傍から順にヒンジ部5へ向けてシール部分が剥離していき、ヒンジ部5の両端部まで剥離が進むと、その位置には切欠部8が設けられているので、その切欠部8で剥離の進行が停止する。従って、可動部2aのみをヒンジ部5まで容易に剥離することができ、固定部2bはそのままフランジ部3にヒートシールされた状態で残る。しかも、切欠部8で仮に剥離の進行を停止できなかった場合でも、その固定部2b側には剥離ストッパーとして強接着部9が近設されているので、その強接着部9によって確実に剥離を停止することができ、蓋体2全体の剥離を防止する。
【0021】
このように、可動部2aのみを剥離して開封した後は、可動部2aの開閉動作によって開口部の所定領域のみの開閉が自在にできるが、固定部2bが嵌合によって容器本体1に固定されている従来のものとは異なり、固定部2bが容器本体1に接着固定されているので、可動部2aを開け閉めする際に固定部2bに力が作用しても、固定部2bの固定状態が維持される。特に、可動部2aは、その裏面側の凸部7の嵌合突出部7aが開口部の内側に嵌合することによって、その閉状態が維持される構成なるため、可動部2aを開ける時には嵌合状態を解除する力が可動部2aを介して固定部2bに作用する。しかし、固定部2bは、裏面側の凸部7の嵌合力のみならず、ヒートシールによる接着力によって容器本体1に固定されているため、可動部2aを開くときにその力が固定部2bに作用しても剥離せずに十分に固定状態が維持される。また、仮に強く引っ張っても、切欠部8と強接着部9によって固定部2bの剥離が未然に防止される。
【0022】
尚、図2に二点破線にて示す如く、可動部2aの開状態は嵌合凸部10の嵌合凹部11への嵌入で維持されるので、可動部2aを手で押さえなくとも、開口から被包装物を容易に所望量取り出すことができる。また、可動部2aの閉状態は、裏面側の凸部7の嵌合突出部7aが開口部の内側に嵌合することで維持されるので、不用意に可動部2aが開くことを防止できる。
このように、開封後において可動部2aを繰り返し開閉しても、切欠部8と強接着部9とによって固定部2bの剥離が防止されるのである。
【0023】
更に、切欠部8と強接着部9とで固定部2bの不用意な剥離を防止しているが、固定部2bは剥離不能ではなく剥離可能にヒートシールされているので、例えば、容器本体1から被包装物を全て取り出した後には、固定部2bを剥離して蓋体2全体を容器本体1から取り外すことも可能である。
【0024】
尚、図4の如く、凹状のヒンジ部5の両端部に切込部12,12を設けて固定部2b側への剥離の進行を阻止してもよい。尚、図4の構成においても、同様に裏面側には固定部2bと可動部2aに容器本体1の開口部の内側に嵌合する嵌合部としての凸部7が各々形成されているが、図5(イ)の如く、その凸部7の表面側の凹部4に可動部2aの嵌合凸部10が嵌入して可動部2aの開状態を保持する構成としてもよい。
【0025】
また、上記説明では、蓋体2の裏面全体にイージーピールシーラント層を設けて可動部2aのみならず固定部2bも剥離可能にヒートシールされる構成としたが、裏面に部分的にイージーピールシーラント層を設けてもよい。即ち、可動部2a側にのみイージーピールシーラント層としてヒートシール剤等をパートコートして、固定部2b側を剥離不能にヒートシールし、可動部2a側を剥離可能にヒートシールする構成としてもよい。尚、裏面全体にイージーピールシーラント層を設けた場合でも、可動部2a側より固定部2b側を高温高圧でヒートシールする等によって、固定部2b側の接着力を可動部2aのそれよりも大きくすることも可能で、これにより、固定部2bの剥離が抑制され、可動部2aの開閉がスムースになる。
【0026】
また、上述では、蓋体2側にイージーピールシーラント層を設けているが、容器本体1側にイージーピールシーラント層を設けてもよく、蓋体2と容器本体1とのシール部分が剥離可能にヒートシール可能な材質であればイージーピールシーラント層を設けなくてもよい。
【0027】
更に、容器本体1の形状も例えば開口縁部にフランジ部3を設けない構成とする等、種々の構成とすることができ、また、固定部2bや可動部2aの容器本体1との嵌合についても、蓋体2が開口部の外側に外嵌する構成としてもよい。更に、可動部2aの個数も限定されず、例えば、固定部2bの両側に各々ヒンジ部5を介して可動部2aを設けてもよい。
【0028】
【発明の効果】
以上のように、蓋体をヒートシールにより接着したことで被包装物を密封包装でき、従来の嵌合のものに比して高い密封性が得られ、しかも、可動部を剥離して開封した後は該可動部を容器本体に嵌合させて閉めることができるので、開封後における蓋体の繰り返しの開閉性にも優れる包装容器が得られる。

Moreover, in the packaging container which concerns on this invention, when the cover body 2 is peeled from the movable part 2a side, in order to stop progress of peeling to the fixed part 2b side, a notch part is provided in the both ends of the hinge part 5. It may be provided. In addition, a notch part is a concept also including a notch part.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, with reference to FIG. 1 to FIG. 3 for one embodiment of the packaging container of the present invention, a bottomed cylindrical container body 1 having an upper surface opened to accommodate an article to be packaged, and an opening of the container body 1 A packaging container provided with a lid 2 attached to the container body 1 to close the container will be described.
[0012]
The container body 1 is formed by vacuum forming or pressure forming from a lid 2 and a heat-sealable plastic sheet. As the plastic sheet, for example, a polypropylene plastic sheet or a sheet having a polypropylene resin on the surface and a gas barrier layer such as an ethylene vinyl alcohol copolymer laminated in the middle is preferable. Layered and multilayer plastic sheets can be used. In addition, it is good also as injection molding, such as a polypropylene resin.
And the flange part 3 is provided in the opening edge part toward the outer side, and the said cover body 2 is adhere | attached on this opening edge part by heat sealing. That is, in this embodiment, the opening of the container body 1 is in a sealed state by heat-sealing the lid body 2 around the entire upper surface of the flange portion 3.
[0013]
The lid 2 is formed from a plastic sheet by sheet molding, and the plastic sheet can adopt various sheets of a single layer or a multilayer having a thickness of about 0.3 mm to 2.0 mm that can be molded, At least the back side is configured to be heat-sealable with the container body 1. In this embodiment, a multilayer sheet in which a polypropylene-based easy peel sealant layer is laminated on a sheet base material made of a polypropylene-based resin is employed, and the easy-peel sealant layer (a sealant layer that can be peeled off or destroyed after heat sealing) ) Are formed in the front and back directions by sheet molding, and heat sealed to the upper surface of the flange portion 3 of the container body 1.
[0014]
The easy peel sealant layer is a single layer in which a polyethylene resin, a polystyrene resin or the like is contained in a polypropylene resin, or a multilayer in which an adhesive layer capable of delamination of 1 to several μm is laminated. As a result, the sealing force is reduced as compared with the sealant layer made of a single polypropylene resin, and the film can be peeled after heat sealing. That is, the lid 2 is heat-sealed to the container body 1 so as to be peelable.
[0015]
Further, the lid body 2 has a substantially circular shape in plan view, and is formed with two substantially semicircular concave portions 4 and 4 which are opened to the surface side by sheet forming so as to face each other. A convex hinge portion 5 is formed on the surface side so as to cross the lid 2. That is, the lid body 2 is divided into two parts by the hinge part 5, one of which is a movable part 2 a that can be opened and closed with the hinge part 5 as a starting point after opening the container, and the other is a container body that is opened and closed when the movable part 2 a is opened and closed. 1 is a fixing portion 2b that is in a fixed state with respect to 1. The movable portion 2a is formed with an opening knob 6 protruding from the outer periphery at a position opposite to the hinge portion 5.
[0016]
Corresponding to the formation of both concave portions 4 and 4 by sheet molding, convex portions 7 and 7 are formed on the back side of the movable portion 2a side and the fixed portion 2b side, respectively, and the outer peripheral side of both convex portions 7 and 7 A plurality of fitting protrusions 7a that protrude slightly outward are formed on the side surface of the first member. The fitting protrusion 7 a is a fitting portion that fits inside the opening of the container body 1. In addition, it is good also as a structure which the convex part 7 (side surface of an outer peripheral side) fits directly in the inside of an opening part, without providing the fitting protrusion part 7a.
[0017]
Further, as shown in FIGS. 1 and 3, notches 8 are formed at both ends of the hinge 5. Further, among the seal portions heat-sealed at the opening edge portion, the strong adhesion portion 9 (FIGS. 1 and 3) adhered to the seal portion on the fixed portion 2b side more strongly than the other portions near the hinge portion 5. The cross-hatch part) is provided. The strong adhesion portion 9 is provided in the vicinity of the fixed portion 2b side of the cutout portion 8, and is heat-sealed at a higher temperature and pressure than the other seal portions.
[0018]
A fitting convex portion 10 is formed on the movable portion 2a side and a fitting concave portion 11 is formed on the fixed portion 2b side with the hinge portion 5 as a boundary, and the movable portion 2a is located upward from the hinge portion 5 as a starting point. When rotated and overlapped above the fixed portion 2b, the fitting convex portion 10 is fitted into the fitting concave portion 11, and the open state of the movable portion 2a can be maintained. In addition, the fitting convex part 10 and the fitting recessed part 11 are provided in pairs along the hinge part 5 at predetermined intervals.
[0019]
In the packaging container configured as described above, the lid body 2 can be easily formed by molding from a single sheet, and since the lid body 2 is heat-sealed to the container body 1, before opening. Thus, the sealed state of the opening can be obtained, and therefore, an object to be packaged that requires high sealing performance can be completely sealed and packaged.
[0020]
Moreover, since the lid 2 is heat-sealed so as to be peelable, the container can be easily opened by peeling the lid 2. At that time, when the knob 6 is picked and the movable part 2a is pulled upward, the seal part is peeled from the vicinity of the knob 6 toward the hinge 5 in order, and the peeling proceeds to both ends of the hinge 5. Since the notch 8 is provided at that position, the progress of peeling stops at the notch 8. Therefore, only the movable part 2a can be easily peeled to the hinge part 5, and the fixed part 2b remains heat-sealed to the flange part 3 as it is. Moreover, even if the progress of the peeling cannot be stopped at the notch 8, the strong bonding portion 9 is provided as a peeling stopper on the fixed portion 2 b side, so that the strong bonding portion 9 ensures the peeling. It is possible to stop and prevent peeling of the entire lid 2.
[0021]
Thus, after only the movable part 2a is peeled and opened, only the predetermined area of the opening can be opened and closed by opening and closing the movable part 2a, but the fixed part 2b is fixed to the container body 1 by fitting. Unlike the conventional one, the fixing portion 2b is fixedly bonded to the container body 1. Therefore, even if a force acts on the fixing portion 2b when opening and closing the movable portion 2a, the fixing portion 2b is fixed. State is maintained. In particular, the movable portion 2a is configured such that its closed state is maintained by fitting the fitting protrusion 7a of the convex portion 7 on the back side inside the opening, so that it is fitted when the movable portion 2a is opened. A force for releasing the combined state acts on the fixed portion 2b via the movable portion 2a. However, since the fixed portion 2b is fixed to the container body 1 not only by the fitting force of the convex portion 7 on the back side but also by the adhesive force by heat sealing, the force is applied to the fixed portion 2b when the movable portion 2a is opened. Even if it acts, the fixed state is sufficiently maintained without peeling. Moreover, even if it pulls strongly, peeling of the fixing | fixed part 2b is prevented by the notch part 8 and the strong adhesion part 9 beforehand.
[0022]
2, the open state of the movable portion 2a is maintained by fitting the fitting convex portion 10 into the fitting concave portion 11, so that the opening can be opened without pressing the movable portion 2a by hand. The desired amount can be easily taken out from the package. In addition, the closed state of the movable portion 2a is maintained by fitting the fitting protrusion 7a of the convex portion 7 on the back surface inside the opening, thereby preventing the movable portion 2a from being opened carelessly. .
Thus, even if the movable part 2a is repeatedly opened and closed after opening, the notch part 8 and the strong adhesion part 9 prevent the fixing part 2b from being peeled off.
[0023]
Further, the inadvertent peeling of the fixing part 2b is prevented by the notch part 8 and the strong adhesion part 9, but the fixing part 2b is not peelable but heat-sealable so that it can be peeled off. After taking out all the items to be packaged from the container, it is possible to remove the fixing part 2b and remove the entire lid 2 from the container body 1.
[0024]
In addition, as shown in FIG. 4, you may provide the notch parts 12 and 12 in the both ends of the concave hinge part 5, and may prevent progress of peeling to the fixing | fixed part 2b side. In the configuration of FIG. 4, similarly, on the back surface side, the fixed portion 2 b and the movable portion 2 a are each formed with a convex portion 7 as a fitting portion that fits inside the opening of the container body 1. As shown in FIG. 5 (a), the fitting convex portion 10 of the movable portion 2a may be fitted into the concave portion 4 on the surface side of the convex portion 7 to hold the open state of the movable portion 2a.
[0025]
Further, in the above description, an easy peel sealant layer is provided on the entire back surface of the lid 2 so that not only the movable portion 2a but also the fixed portion 2b is heat-sealable, but the easy peel sealant is partially applied to the back surface. A layer may be provided. That is, it is good also as a structure which part-coats a heat seal agent etc. as an easy peel sealant layer only to the movable part 2a side, heat-seals the fixed part 2b side so that peeling is impossible, and heat-seals the movable part 2a side so that peeling is possible. . Even when the easy peel sealant layer is provided on the entire back surface, the adhesive force on the fixed portion 2b side is larger than that on the movable portion 2a by heat sealing the fixed portion 2b side from the movable portion 2a side at a high temperature and high pressure. It is also possible to suppress the peeling of the fixed portion 2b and to smoothly open and close the movable portion 2a.
[0026]
In the above description, the easy peel sealant layer is provided on the lid body 2 side. However, an easy peel sealant layer may be provided on the container body 1 side, and the seal portion between the lid body 2 and the container body 1 can be peeled off. If the material can be heat sealed, the easy peel sealant layer may not be provided.
[0027]
Further, the shape of the container body 1 can be variously configured, for example, such that the flange portion 3 is not provided at the opening edge, and the fixed portion 2b and the movable portion 2a are fitted to the container body 1. The lid 2 may be externally fitted to the outside of the opening. Furthermore, the number of the movable parts 2a is not limited. For example, the movable parts 2a may be provided on both sides of the fixed part 2b via the hinge parts 5, respectively.
[0028]
【The invention's effect】
As described above, the lid can be bonded by heat sealing, so that the packaged object can be hermetically packaged. Higher sealing performance than that of the conventional fitting is obtained, and the movable part is peeled off and opened. Thereafter, the movable part can be fitted to the container body and closed, so that a packaging container having excellent repetitive opening and closing of the lid after opening can be obtained.
