Description

本発明は、水蒸気や酸素などのガスに対するバリア性を有する熱収縮性筒状ラベルで被覆されたガスバリア性容器に関する。   The present invention relates to a gas barrier container coated with a heat-shrinkable cylindrical label having a barrier property against gases such as water vapor and oxygen.

従来、即席麺や菓子などの食品、飲料、調味料、医薬品、化粧品などの収納物を密封保存する容器体として、例えば、発泡スチロール製のカップ状容器体、ポリエチレンテレフタレート製ボトルのような合成樹脂製のボトル状容器体、樹脂がコーティング又は積層された紙製の容器体などが広く用いられている。このような容器体は、水蒸気や酸素などのガスバリア性が比較的低いため、これを高める手段として、例えば、特開2001−278284号公報などに示すように、容器体の胴部に酸素ガスバリア性を有する筒状ラベルを装着したものや、容器体全体に水蒸気バリア性を有する熱収縮性フィルムをオーバーラップしたものなどが知られている。   Conventionally, as containers for storing stored items such as foods such as instant noodles and confectionery, beverages, seasonings, pharmaceuticals, cosmetics, etc., for example, cup-shaped containers made of polystyrene foam, synthetic resin such as polyethylene terephthalate bottles A bottle-shaped container body, a paper container body on which a resin is coated or laminated, and the like are widely used. Since such a container body has a relatively low gas barrier property such as water vapor and oxygen, as a means for enhancing this, for example, as shown in Japanese Patent Application Laid-Open No. 2001-278284, an oxygen gas barrier property is provided on the body portion of the container body. There are known ones equipped with a cylindrical label having, and those in which a heat shrinkable film having a water vapor barrier property is overlapped on the entire container body.

上記筒状ラベルを胴部に装着したガスバリア性容器は、筒状ラベルが比較的厚いので、装着された胴部においては容器体の内部又は外部へのガス透過を防止できるが、容器体の底面が露出しているので、その部分から酸素などが透過し、十分なガスバリア性を確保できない。一方、オーバーラップフィルムで包装したものは、熱収縮させる際の脱気孔が存在するため、そこから水蒸気や酸素などが入り込み、十分なガスバリア性を確保できない。また、この脱気孔を塞ぐため、ラベルなどを貼着するなどの手段も知られているが、該ラベルやその貼着工程が必要であり、仮に脱気孔を塞いでもオーバーラップフィルム自体は比較的薄いので、同様にガスバリア性が十分とは言えない。
特開2001−278284号公報(第3頁の[0010]、[0011]及び図1等)
The gas barrier container having the cylindrical label attached to the body part has a relatively thick cylindrical label, and the attached body part can prevent gas permeation to the inside or outside of the container body. Since oxygen is exposed, oxygen or the like permeates therethrough, and sufficient gas barrier properties cannot be secured. On the other hand, what is wrapped with an overlap film has deaeration holes when it is thermally contracted, so that water vapor, oxygen, and the like enter from there, and a sufficient gas barrier property cannot be secured. In addition, in order to block this deaeration hole, a means such as sticking a label is also known, but the label and its bonding process are necessary, and even if the deaeration hole is blocked, the overlap film itself is relatively Since it is thin, it cannot be said that the gas barrier property is sufficient.
JP 2001-278284 A ([0010], [0011] on FIG. 3 and FIG. 1 etc.)

本発明は、ガスバリア性を有する熱収縮性筒状ラベルを用い、優れた防湿性、酸化防止、保香性などを備えるガスバリア性容器を提供することを課題とする。   It is an object of the present invention to provide a gas barrier container using a heat-shrinkable cylindrical label having gas barrier properties and having excellent moisture proofing properties, antioxidant properties, aroma retention properties, and the like.

以下、本発明について、図面を参照しつつ具体的に説明する。尚、本明細書に於いて方向を示す用語としての「上」、「下」は、容器体を自立させた(接地部を載置面上に載置した)状態を基準とする。
図1及び図2に於いて、1は、ガスバリア性を有する熱収縮性筒状ラベルによって、容器体2の少なくとも胴部21及び底面22が被覆されているガスバリア性容器を示す。
Hereinafter, the present invention will be specifically described with reference to the drawings. In the present specification, “upper” and “lower” as terms indicating directions are based on a state in which the container body is self-supported (the grounding portion is placed on the placement surface).
1 and 2, reference numeral 1 denotes a gas barrier container in which at least the body portion 21 and the bottom surface 22 of the container body 2 are covered with a heat-shrinkable cylindrical label having gas barrier properties.

具体的には、容器体2は、例えば、即席麺などを収納可能な発泡スチロール製成形体からなり、底面22が閉塞され且つ上面が開口されていると共に、下方に向かうに従い縮径する胴部21を有する略カップ形状に形成されている。この底面22は、その周囲に、台上などの載置面に容器体2を自立させるため、該載置面に接する接地部23が下方に突設されている。さらに、底面22の外面には、この接地部23で囲繞されるように、内側に凹んだ凹部24が形成されている。また、容器体2の胴部21の上端部には、鍔状のフランジ部25が形成されている。このフランジ部25の上面には、水蒸気、酸素、香気成分などに対するガスバリア性を有するシート状の蓋部26が剥離可能な状態で貼着され、これにより開口部27が閉塞されている。かかる蓋部26としては、例えば、合成樹脂製フィルムや紙などの基材にガスバリア性を有する金属箔(アルミ箔等)などが積層されたラミネート材などが例示される。
尚、28は、凹凸のない平坦な外周面を有する胴部21の上方部を示し、29は、接地部23と凹部24によって区画される空間を示す。
Specifically, the container body 2 is made of, for example, a foamed polystyrene molded body that can store instant noodles and the like, the bottom surface 22 is closed, the top surface is opened, and the body portion 21 is reduced in diameter toward the lower side. It is formed in the substantially cup shape which has. In order to make the container body 2 stand on a mounting surface such as a table, the bottom surface 22 is provided with a grounding portion 23 in contact with the mounting surface. Further, a concave portion 24 recessed inward is formed on the outer surface of the bottom surface 22 so as to be surrounded by the grounding portion 23. Further, a flange-like flange portion 25 is formed at the upper end portion of the body portion 21 of the container body 2. On the upper surface of the flange portion 25, a sheet-like lid portion 26 having a gas barrier property against water vapor, oxygen, fragrance components and the like is attached in a peelable state, thereby closing the opening 27. Examples of the lid 26 include a laminate material in which a metal foil (aluminum foil or the like) having gas barrier properties is laminated on a base material such as a synthetic resin film or paper.
Reference numeral 28 denotes an upper portion of the body portion 21 having a flat outer peripheral surface without unevenness, and 29 denotes a space defined by the ground contact portion 23 and the recessed portion 24.

かかる容器体2の胴部21及び底面22を被覆するように、ガスバリア性を有する熱収縮性筒状ラベル3が熱収縮により装着されている。この筒状ラベル3の上方側は、容器体2の胴部21の外面形状に沿って熱収縮装着された胴部装着部31であり、一方、筒状ラベル3の下方側は、容器体2の内側に向かうに従い次第に大きく熱収縮して装着され且つ筒状ラベル3の下方開口部が閉塞された底面装着部32である。
より具体的には、筒状ラベル3の胴部装着部31は、ガスバリア性の蓋部26と実質的に連続して容器体2を被覆すべく、筒状ラベル3の上縁3aを容器体2のフランジ部25に接し又はフランジ部25の近傍に位置させた状態で、容器体2の胴部21に熱収縮により装着されている。さらに、図2に示すように、胴部装着部31の上端内周面3bの全周は、胴部21の上方部28の外周面に密封状に貼着されている。この上端内周面3bを貼着する手段としては、図示したように接着剤又は粘着剤などの貼着剤層4を介在させたり、上端内周面3bを熱融着させる手段などを用いることができるが、簡易に且つ確実に密封状に貼着できることから、接着剤又は粘着剤を介して貼着することが好ましい。この接着剤又は粘着剤の種類は特に限定されず、ホットメルト接着剤、溶剤型接着剤、二液硬化型接着剤、エマルジョン型接着剤などの各種接着剤、ホットメルト粘着剤、感圧型粘着剤などの各種粘着剤を用いることができるが、常温で接着性(粘着性)を示さず且つ筒状ラベル3の熱収縮装着時の熱を利用して貼着できることから、感熱型接着剤(ホットメルトタイプやディレードタックタイプ)を筒状ラベル3の内面に塗布して用いることが好ましい。
A heat-shrinkable cylindrical label 3 having a gas barrier property is attached by heat shrink so as to cover the body portion 21 and the bottom surface 22 of the container body 2. The upper side of the cylindrical label 3 is a body mounting portion 31 that is heat-shrink mounted along the outer surface shape of the body 21 of the container body 2, while the lower side of the cylindrical label 3 is the container body 2. This is a bottom surface mounting portion 32 that is gradually heat-shrinked toward the inner side and is mounted while the lower opening of the cylindrical label 3 is closed.
More specifically, the body mounting portion 31 of the cylindrical label 3 is configured so that the upper edge 3a of the cylindrical label 3 is covered with the container body so as to cover the container body 2 substantially continuously with the gas barrier lid portion 26. 2 is attached to the body portion 21 of the container body 2 by heat shrinkage while being in contact with the flange portion 25 or being located in the vicinity of the flange portion 25. Further, as shown in FIG. 2, the entire circumference of the upper end inner peripheral surface 3 b of the trunk portion mounting portion 31 is adhered to the outer peripheral surface of the upper portion 28 of the trunk portion 21 in a sealing manner. As a means for adhering the upper end inner peripheral surface 3b, as shown in the figure, an adhesive or adhesive layer 4 such as an adhesive or an adhesive is interposed, or means for thermally fusing the upper end inner peripheral surface 3b is used. However, since it can be simply and reliably attached in a sealed manner, it is preferably attached via an adhesive or a pressure-sensitive adhesive. The type of the adhesive or pressure-sensitive adhesive is not particularly limited, and various adhesives such as a hot-melt adhesive, a solvent-type adhesive, a two-part curable adhesive, and an emulsion-type adhesive, a hot-melt pressure-sensitive adhesive, and a pressure-sensitive pressure-sensitive adhesive However, since it does not show adhesiveness (adhesiveness) at room temperature and can be attached using heat at the time of heat-shrinking of the cylindrical label 3, a heat-sensitive adhesive (hot It is preferable to apply a melt type or a delayed tack type) to the inner surface of the cylindrical label 3 for use.

一方、筒状ラベル3の底面装着部32は、胴部21と底面22の境界で略直角に湾曲し、接地部23の形状に沿いながら底面22の内側(容器体2の中心軸側)に向かうに従い次第に大きく熱収縮した略水平部分を有すると共に、この略水平部分に繋がる筒状ラベル3の下端部34は、重ね合わされることにより、閉塞部35を構成している。この閉塞部35は、筒状ラベル3の下方開口部を閉塞する部分であり、下方開口部を略完全に閉じるように略扁平状にしてラベル外面3cに添着されている。また、閉塞部35は、容器体2の空間29内に位置して(空間29内に納まるように)設けられている。

On the other hand, the bottom surface mounting portion 32 of the cylindrical label 3 is bent at a substantially right angle at the boundary between the body portion 21 and the bottom surface 22, and is located inside the bottom surface 22 (on the central axis side of the container body 2) along the shape of the ground contact portion 23. While having a substantially horizontal portion that is gradually heat-shrinked as it goes, the lower end portion 34 of the cylindrical label 3 connected to the substantially horizontal portion is overlapped to constitute a closed portion 35. The closing portion 35 is a portion that closes the lower opening of the cylindrical label 3, and is attached to the label outer surface 3c in a substantially flat shape so as to close the lower opening substantially completely. Further, the closing portion 35 is provided in the space 29 of the container body 2 (so as to be accommodated in the space 29).
For example, as shown in FIGS. 3A-1 and 3A, the closing portion 35 has a shape in which one piece 34a of the lower end 34 is folded inward and the other piece 34b is folded thereon, as shown in FIG. As shown in FIGS. 1 and 2, the inner surface of the lower end 34 is overlapped into a plate shape, and the overlapped portion 34c of the plate is folded into the label outer surface 3c, as shown in FIG. The lower end 34 is twisted together, and the twisted overlapping portion 34d is folded into the label outer surface 3c, and the lower end 34 is regularly aligned, attached to the label outer surface 3c, and plastically deformed. The lower end 34 is disordered, such as a configuration in which the heat is set flat, or a shape in which the lower end 34 is arbitrarily overlapped and attached to the outer surface 3c of the label as shown in FIGS. Is attached to the outer surface 3c of the label and plastically deformed. Such configuration in which heat setting is illustrated in a substantially flat Te.

This is a cylindrical body formed by center-sealing both ends 5a, 5a of a label base 5 having a long length, and a predetermined display such as a product name or an advertisement is printed on a predetermined portion of the inner surface or outer surface thereof. A designed print layer (not shown) is provided. A strip-shaped adhesive layer 4 made of a hot-melt type heat-sensitive adhesive is provided around the inner peripheral surface 3 b at the upper end of the cylindrical label 3.

次に、筒状ラベル3を構成するラベル基材5は、水蒸気、酸素、香気成分、二酸化炭素などのガス成分に対するバリア性を有する熱収縮性フィルムからなり、好ましくは、各種ガス成分のうち、水蒸気、酸素、香気成分の少なくとも何れかに対してガスバリア性を有する熱収縮性フィルムからなる。このようなフィルムとしては、公知のものを適宜用いることができる。
主として水蒸気バリア性を有する熱収縮性フィルムとしては、水蒸気透過度(40℃、90%RH)が20g/m2・24hr以下のフィルムが好ましく、例えば、エチレン−プロピレンランダム共重合体などのポリプロピレン系フィルムや、プロピレン系樹脂100重量部に水添石油樹脂が10〜30重量部程度配合されたポリプロピレン系フィルム(特開昭60−210647号公報など)や、更に水蒸気バリア性に優れるものとして、これらプロピレン系樹脂層の表面に非晶性オレフィン系樹脂層を積層した積層フィルム(特開2002−59969号公報など)や、ポリスチレン系又はポリエステル系のフィルムにポリ塩化ビニリデン系樹脂をコーティングした熱収縮性フィルムなどが例示される。

さらに、主として香気バリア性を有する熱収縮性フィルムとしては、香気成分の種類により異なるが、一般的にはエチレン−ビニルアルコール共重合体フィルム又はポリエステルフィルム及びその積層フィルムや、特定のエチレン共重合体とポリエステルの積層フィルム(特開2000−135761号公報など)などが例示される。
尚、例えば、上記水蒸気バリア性を有するフィルムに、酸素ガスバリア性及び香気バリア性に優れるエチレン−ビニルアルコール共重合体を含む層を積層したり、或いは上記例示以外のガスバリア性フィルムを用いることなどによって、水蒸気、酸素、香気成分などから選ばれる2種以上のガス成分に対するバリア性を有する熱収縮性フィルムで、筒状ラベル3を構成することも可能である。
Next, the label substrate 5 constituting the cylindrical label 3 is made of a heat-shrinkable film having a barrier property against gas components such as water vapor, oxygen, aroma components, carbon dioxide, and preferably, among various gas components, It consists of a heat-shrinkable film having a gas barrier property against at least one of water vapor, oxygen and aroma components. As such a film, a well-known thing can be used suitably.
As the heat-shrinkable film mainly having a water vapor barrier property, a film having a water vapor permeability (40 ° C., 90% RH) of 20 g / m 2 · 24 hr or less is preferable. For example, a polypropylene-based film such as an ethylene-propylene random copolymer As a film, a polypropylene film in which about 10 to 30 parts by weight of a hydrogenated petroleum resin is blended in 100 parts by weight of a propylene-based resin (JP-A-60-210647, etc.), and those having excellent water vapor barrier properties, these Heat shrinkability of a laminated film (such as JP-A-2002-59969) in which an amorphous olefin resin layer is laminated on the surface of a propylene resin layer, or a polyvinylidene chloride resin coated on a polystyrene or polyester film. A film etc. are illustrated.
Further, as the heat-shrinkable film mainly having an oxygen gas barrier property, a film having an oxygen permeability (20 ° C., 65% RH) of 20 cc / m 2 · 24 hr · atm (196 ml / m 2 · d · MPa) or less is preferable. For example, an ethylene-vinyl alcohol copolymer, polyvinyl alcohol, polyvinylidene chloride, metaxylenediamine, and adipic acid are added to a thermoplastic resin layer such as a polystyrene type, a polyester type such as polyethylene terephthalate, or a polyolefin type such as polyethylene or polypropylene.

In addition, for example, by laminating a layer containing an ethylene-vinyl alcohol copolymer excellent in oxygen gas barrier property and aroma barrier property on the film having water vapor barrier property, or by using a gas barrier film other than those exemplified above It is also possible to form the cylindrical label 3 with a heat-shrinkable film having a barrier property against two or more kinds of gas components selected from water vapor, oxygen, aroma components and the like.

上記熱収縮性フィルムは、溶融押出、共押出などの公知の製法により、製膜し延伸することによって得ることができる。また、各種ガスバリア層は、前記押出で形成するほか、延伸後に各種ラミネートやコーティングによって積層し形成することもできる。延伸処理は、通常、70〜110℃程度の温度で、幅方向(筒状ラベル3とした場合に周方向)に2.0〜8.0倍、好ましくは3.0〜7.0倍程度延伸することにより行われる。さらに、必要に応じて、長手方向(縦方向)にも、例えば1.5倍以下の低倍率で延伸処理を行ってもよい。   The heat-shrinkable film can be obtained by film formation and stretching by a known production method such as melt extrusion or coextrusion. The various gas barrier layers can be formed by the extrusion, or can be formed by laminating by various laminates or coatings after stretching. The stretching treatment is usually at a temperature of about 70 to 110 ° C., and is about 2.0 to 8.0 times, preferably about 3.0 to 7.0 times in the width direction (in the circumferential direction when the cylindrical label 3 is used). This is done by stretching. Furthermore, if necessary, the stretching process may be performed in the longitudinal direction (longitudinal direction) at a low magnification of, for example, 1.5 times or less.

フィルムの熱的性質は、少なくとも幅方向(筒状ラベルとした場合に周方向)に於ける熱収縮率(80℃の温水中に10秒間浸漬)が約30%以上、好ましくは約40%、より好ましくは約50%以上のフィルムを用いることが好ましい。尚、熱収縮後の筒状ラベル3の下方開口部の内径をより小さくできることから、出来るだけ熱収縮率が大きいもの(フィルムの種類によって異なるが概ね70〜80%程度)が好ましい。尚、長手方向についても若干熱収縮する熱収縮性フィルムが好ましい。
また、ラベル基材5の厚みは、30〜90μm程度であるが、30〜50μmのものが好ましい。
The thermal properties of the film are such that the thermal shrinkage rate (immersion for 10 seconds in warm water at 80 ° C.) in at least the width direction (circumferential direction in the case of a cylindrical label) is about 30% or more, preferably about 40%. More preferably, a film of about 50% or more is used. In addition, since the internal diameter of the downward opening part of the cylindrical label 3 after heat contraction can be made smaller, the thing with as large a heat contraction rate as possible (depending on the kind of film is about 70 to 80%) is preferable. A heat-shrinkable film that slightly shrinks in the longitudinal direction is preferred.
Moreover, although the thickness of the label base material 5 is about 30-90 micrometers, the thing of 30-50 micrometers is preferable.

次に、上記筒状ラベル3を容器体2に装着する方法及びガスバリア性容器1の製造方法について説明する。
図5に示すように、容器体2を逆さにして載置面10上に載置し、筒状ラベル3の上縁3a(尚、容器体2を逆にして示した関係上、一般的に言うところの上下関係は図5と一致しないが、あくまで容器体2を自立させた状態を基準として「上」「下」の用語を使用している)を容器体2のフランジ部25と略同レベルに位置させて、筒状ラベル3を容器体2に挿入する。次いで、これを温風などを備えるシュリンクゾーンに導いて、この筒状ラベル3を熱収縮させる。このシュリンクゾーンの加熱により、貼着剤層4の感熱型接着剤が軟化して接着(粘着)性を発現し、筒状ラベル3の上端内周面3bは容器体2の外周面に貼着されるが、感熱型接着剤を確実に軟化させるために、これを集中的に加熱するヒーターなどの別途の加熱装置を併用してもよい。
かかる熱収縮により、図6に示すように、筒状ラベル3は、容器体2の胴部21に装着され、且つ底面22に於いて内側に次第に大きく熱収縮した略水平な部分が形成されると共に、底面22中央部に、非装着部分として、下方開口部33を含む筒状の下端部34が突出した状態となる。
熱収縮温度は、フィルムの種類に応じて適宜設計されるものであって通常80〜200℃程度であるが、熱収縮後の下方開口部33の開口面積をより小さくできることから、フィルムの収縮限界又はこの近くまで収縮する温度で熱収縮させるのが好ましい。
Next, a method for mounting the cylindrical label 3 on the container body 2 and a method for manufacturing the gas barrier container 1 will be described.
As shown in FIG. 5, the container body 2 is inverted and placed on the placement surface 10, and the upper edge 3 a of the cylindrical label 3 ( The above-mentioned vertical relationship does not coincide with FIG. 5, but the terms “upper” and “lower” are used to the same extent as the flange portion 25 of the container body 2 based on the state in which the container body 2 is self-supporting. The cylindrical label 3 is inserted into the container body 2 at the level. Subsequently, this is led to a shrink zone provided with warm air or the like, and the cylindrical label 3 is thermally contracted. By heating the shrink zone, the heat-sensitive adhesive of the adhesive layer 4 is softened and develops adhesiveness (adhesion), and the upper inner peripheral surface 3 b of the cylindrical label 3 is adhered to the outer peripheral surface of the container body 2. However, in order to surely soften the heat-sensitive adhesive, a separate heating device such as a heater that heats the heat-sensitive adhesive may be used in combination.
Due to such heat shrinkage, as shown in FIG. 6, the cylindrical label 3 is attached to the body portion 21 of the container body 2, and a substantially horizontal portion which is gradually heat-shrinked on the bottom surface 22 is formed. At the same time, a cylindrical lower end 34 including the lower opening 33 protrudes as a non-mounting portion at the center of the bottom surface 22.
The heat shrink temperature is appropriately designed according to the type of film and is usually about 80 to 200 ° C. However, since the opening area of the lower opening 33 after heat shrink can be made smaller, the shrinkage limit of the film Alternatively, it is preferable that the heat shrinkage is performed at a temperature that shrinks to the vicinity.

次に、熱収縮時の余熱によって筒状ラベル3の下端部34が軟化しているうちに、図6に示すように、空間29内に進入可能な治具11を、下端部34に押し当てながらこれを凹部24側へと押圧し、下端部34を空間29内に押し潰す。押し潰された下端部31は、扁平状となって下方開口部33が閉塞された閉塞部35を構成する。
その後、治具11を離すと、下端部34は、塑性変形により略扁平状の塊となってラベル外面3cに添着し、図1に示すように、閉塞部35が空間29内に納められ、且つこの状態を維持できるガスバリア性容器1を製造できる。
Next, while the lower end portion 34 of the cylindrical label 3 is softened due to the residual heat during heat shrinkage, the jig 11 that can enter the space 29 is pressed against the lower end portion 34 as shown in FIG. While pressing this toward the concave portion 24 side, the lower end portion 34 is crushed into the space 29. The crushed lower end portion 31 constitutes a closed portion 35 having a flat shape and a lower opening portion 33 closed.
Thereafter, when the jig 11 is released, the lower end portion 34 becomes a substantially flat lump by plastic deformation and is attached to the outer surface 3c of the label, and as shown in FIG. And the gas barrier container 1 which can maintain this state can be manufactured.

上記構成からなるガスバリア性容器1は、容器体2の胴部21及び底面22がガスバリア性のラベル3で被覆されているので、外部から容器体2内部へ、水蒸気、酸素などが透過することを防止でき、又、逆に容器体2内部から外部へ、香気成分、炭酸ガスなどが拡散することを防止できる。
従って、本発明のガスバリア性容器1は、防湿性、酸化防止、保香性などを確保でき、収納物の品質保持容器として優れている。
特に、筒状ラベル3の上端内周面3bが、胴部21の外周面に貼着されているので、装着された筒状ラベル3の上縁3aと容器体2の間に生じる侵入口が塞がれ、該侵入口を通じて、水蒸気や酸素などが容器体2外面と筒状ラベル3内面の間の隙間12に侵入することを防止できる。また、容器体2を透過した収納物の香気成分などが、隙間12から侵入口を通じて外部に拡散することも防止することができる。
また、筒状ラベル3は、蓋部26と実質的に連続して装着されているので、このガスバリア性の蓋部26と相俟って、容器体2全体がガスバリア性の部材で被覆され(容器体2の外面が実質的に露出しない)、かかるガスバリア性容器1は、防湿性、酸化防止、保香性などに極めて優れている。
In the gas barrier container 1 having the above-described configuration, the body 21 and the bottom surface 22 of the container body 2 are covered with the gas barrier label 3, so that water vapor, oxygen, and the like permeate from the outside into the container body 2. On the contrary, it is possible to prevent the fragrance component, carbon dioxide gas and the like from diffusing from the inside of the container body 2 to the outside.
Therefore, the gas barrier container 1 of the present invention can ensure moisture proofing, oxidation prevention, fragrance retention, etc., and is excellent as a quality maintaining container for stored items.
In particular, since the inner peripheral surface 3b at the upper end of the cylindrical label 3 is adhered to the outer peripheral surface of the body portion 21, there is an intrusion opening generated between the upper edge 3a of the mounted cylindrical label 3 and the container body 2. It is blocked and water vapor, oxygen, and the like can be prevented from entering the gap 12 between the outer surface of the container body 2 and the inner surface of the cylindrical label 3 through the intrusion port. In addition, it is possible to prevent the fragrance components of the stored items that have passed through the container body 2 from diffusing to the outside from the gap 12 through the entry port.
Further, since the cylindrical label 3 is mounted substantially continuously with the lid portion 26, the entire container body 2 is covered with a gas barrier member together with the gas barrier lid portion 26 ( The outer surface of the container body 2 is not substantially exposed), and the gas barrier container 1 is extremely excellent in moisture resistance, oxidation prevention, fragrance retention, and the like.

尚、本発明は上記各実施形態に限定されるものではなく、本発明の意図する範囲で、適宜の構成を付加、代用、設計変更などすることができる。以下、変形例について、主として異なる部分を説明し、同様の構成については、用語及び図番を援用し、その説明を省略することがある。
(容器体について)
上記実施形態に於いて、容器体2としては、発泡スチロール製のカップ状容器体2を例示しているが、これに限られず、例えば、図7(a)に示すように、開口部27を封止可能で且つガスバリア性を有するキャップ状の蓋部26が設けられたボトル状容器体2などに適用してもよい。
また、水蒸気バリア性(防湿性)の低い素材として、ポリスチレン系樹脂(発泡スチロールを含む)、紙、ポリエチレンテレフタレートなどの容器体2に、ポリプロピレン系樹脂製熱収縮性フィルムなどからなる水蒸気バリア性を有する筒状ラベル3を装着すると、水蒸気バリア性が良好となり効果的と言えるが、本発明は、ポリエチレン系樹脂、ポリプロピレン系樹脂などの防湿性を有する素材から形成された容器体2に対して、環状ポリオレフィンなどの水蒸気バリア性に優れた素材を積層した筒状ラベル3を装着することで、更に防湿性を向上させることができ有効である。
また、同様に、ポリスチレン系樹脂、ポリエチレン系樹脂、ポリプロピレン系樹脂、ポリエチレンテレフタレートなどの酸素ガスバリア性の低い素材からなる容器体2に、酸素ガスバリア性を有する筒状ラベル3を装着する場合に限られず、ポリプロピレン系樹脂とエチレン−ビニルアルコール共重合体を積層したカップ状容器体やポリエチレンテレフタレートなどのポリエステルとMXナイロンを積層したブロー成形ボトルなどの酸素ガスバリア性を有する容器体2に装着することでガスバリア性をさらに向上させることもできる。さらに、容器体2を形成する樹脂などに、吸湿剤や酸素吸収剤を混合又は積層した容器体2を用いた場合には、筒状ラベル3によって、外気(水蒸気や酸素)の侵入を防止できるため、吸湿剤や酸素吸収剤の早期飽和を防止して、容器体2内部の残存水蒸気や残存酸素を確実に除去することができる
The present invention is not limited to the above-described embodiments, and appropriate configurations can be added, substituted, and changed in design within the scope intended by the present invention. Hereinafter, different parts will be mainly described with respect to the modified examples, and the same configuration may be referred to using terms and figure numbers, and the description thereof may be omitted.
(About the container)
In the above embodiment, the container body 2 is exemplified by the cup-shaped container body 2 made of styrene foam, but is not limited to this. For example, as shown in FIG. You may apply to the bottle-shaped container body 2 etc. in which the cap-shaped cover part 26 which can be stopped and has gas barrier property was provided.
In addition, as a material having a low water vapor barrier property (moisture resistance), the container body 2 such as polystyrene resin (including foamed polystyrene), paper, polyethylene terephthalate, etc. has a water vapor barrier property made of a heat shrinkable film made of polypropylene resin, etc. When the cylindrical label 3 is attached, it can be said that the water vapor barrier property is good and effective. However, the present invention provides an annular shape with respect to the container body 2 formed of a moisture-proof material such as polyethylene resin and polypropylene resin. It is effective that the moisture-proof property can be further improved by attaching the cylindrical label 3 in which a material having excellent water vapor barrier properties such as polyolefin is laminated.
Similarly, the present invention is not limited to the case where the cylindrical label 3 having an oxygen gas barrier property is attached to the container body 2 made of a material having a low oxygen gas barrier property such as a polystyrene resin, a polyethylene resin, a polypropylene resin, or polyethylene terephthalate. Gas barrier by attaching to a container body 2 having an oxygen gas barrier property, such as a cup-shaped container body laminated with a polypropylene resin and an ethylene-vinyl alcohol copolymer, or a blow molded bottle laminated with polyester such as polyethylene terephthalate and MX nylon The sex can be further improved. Furthermore, when the container body 2 in which a hygroscopic agent or an oxygen absorbent is mixed or laminated on the resin or the like forming the container body 2, the cylindrical label 3 can prevent the outside air (water vapor or oxygen) from entering. Therefore, early saturation of the hygroscopic agent and the oxygen absorbent can be prevented, and the residual water vapor and residual oxygen inside the container body 2 can be reliably removed.

(熱収縮性筒状ラベルについて)
上記実施形態に於いて、筒状ラベル3は、容器体2の胴部21及び底面22に被覆されているが、例えば、図7(b)に示すように、蓋部26の一部まで被覆するようにしてもよいし、又、特に図示しないが、(底面と同様にして閉塞部35を設けて)蓋部26全体を被覆するようにしてもよい。もちろん、カップ状容器体やその他の形状の容器体にも適用できる(以下、同様)。
さらに、リサイクルを考慮して、筒状ラベル3を除去し易くするために、図7(a)に示すように、筒状ラベル3の所定位置に、非貫通のミシン目やハーフカットの切取り線などのような非貫通型の易開裂手段14を設けてもよい。
また、上記実施形態に於いて、筒状ラベル3は、上端内周面3b(蓋部26近傍の内周面)において周帯状に貼着されているので、容器体2と筒状ラベル3の隙間12に外気が入り込む侵入口を閉塞でき、更に、筒状ラベル3の脱落を防ぎ且つ使用後の除去も容易で好ましいものであるが、これに限られず、筒状ラベル3の胴部装着部31の中途部分において周帯状の貼着されていてもよく、また、筒状ラベルの内面略全体を貼着してもよい。尚、容器体2の形状や材質などによっては、筒状ラベル3を非貼着としてもよい。
(About heat-shrinkable cylindrical labels)
In the above embodiment, the cylindrical label 3 is covered with the body portion 21 and the bottom surface 22 of the container body 2. For example, as shown in FIG. Although not particularly shown, the entire lid portion 26 may be covered (provided with the closing portion 35 in the same manner as the bottom surface). Of course, the present invention can also be applied to cup-shaped containers and other shapes (hereinafter the same).
Further, in order to facilitate removal of the cylindrical label 3 in consideration of recycling, as shown in FIG. 7A, a non-penetrating perforation or half-cut tear line is formed at a predetermined position of the cylindrical label 3 as shown in FIG. A non-penetrating type easy-cleavage means 14 such as may be provided.
Moreover, in the said embodiment, since the cylindrical label 3 is affixed on the upper end inner peripheral surface 3b (inner peripheral surface of the cover part 26 vicinity) at the periphery belt shape, the container body 2 and the cylindrical label 3 are attached. Although it is possible to close the entrance through which the outside air enters the gap 12, and further prevents the cylindrical label 3 from dropping off and is easy to remove after use, it is not limited to this, but the body mounting portion of the cylindrical label 3 is not limited thereto. In the middle part of 31, a peripheral belt shape may be attached, or substantially the entire inner surface of the cylindrical label may be attached. Depending on the shape and material of the container body 2, the cylindrical label 3 may be not attached.

(閉塞部について)
上記実施形態に於いて、閉塞部35は、凹部24の空間29内に位置して設けられているので、これが接地部23の下方に突出せず、従って、自立安定性に優れ且つゴミなどが付着し難いなどの利点があり好ましいものであるが、例えば、図8に示すように、該空間29外であって、凹部対応位置に閉塞部35を設けてもよい。このように閉塞部35が凹部対応位置に設けられていると、ガスバリア性容器1を自立させた際、ラベル3の撓みよって閉塞部35が凹部24へと納まるので(二点鎖線で示す)、自立安定性は確保できる。
さらに、上記実施形態に於いて、閉塞部35は、下端部34を熱塑性変形させて熱融着して下方開口部33を閉塞しているが、熱による塑性変形に限られず、例えば、接着剤や溶剤などを用いて、下方開口部33を閉塞するように、下端部34を接着して閉塞部35を構成してもよい。
(About occlusion)
In the above embodiment, the closing portion 35 is provided in the space 29 of the concave portion 24. Therefore, the closing portion 35 does not protrude below the grounding portion 23. Therefore, it has excellent self-standing stability and dust or the like. For example, as shown in FIG. 8, a blocking portion 35 may be provided outside the space 29 and at a position corresponding to the concave portion. When the closed portion 35 is provided at the position corresponding to the concave portion in this way, when the gas barrier container 1 is made to stand on its own, the closed portion 35 is accommodated in the concave portion 24 by bending of the label 3 (indicated by a two-dot chain line). Independence stability can be secured.
Further, in the above-described embodiment, the closing portion 35 has the lower end portion 34 thermoplastically deformed and heat-sealed to close the lower opening portion 33. However, the closing portion 35 is not limited to plastic deformation due to heat. Alternatively, the closing portion 35 may be configured by adhering the lower end portion 34 so as to close the lower opening portion 33 using a solvent or the like.
