Description

本発明は、少なくとも開口部における外周面が該開口部側から底部に向かって半径方向内側に径が漸次減少する容器本体と該容器本体の開口部を閉塞する蓋付き容器に関する。   The present invention relates to a container main body whose diameter gradually decreases radially inward from the opening side toward the bottom, and a container with a lid that closes the opening of the container main body.

従来、容器等に対して栓抜きなどの開封器具を用いることなく蓋部材を開封できる手段として、蓋部材の天面壁に連なるスカート壁の一部に端縁から突出するようなプルリングなどの把持部が設けられ、該把持部の付け根からスカート壁、さらには天面壁に延びている弱化線であるスコアを形成した蓋付き容器が知られている。
このような蓋付き容器の容器本体の開口部には、閉栓時に蓋部材を係止させるために、該開口部の周囲に容器本体の半径方向外側に突出するビード状の突状部を形成している（下記の特許文献１の図６参照）。しかしながら、容器本体を用いて飲料を飲む際には、突状部がユーザ等の唇に当たるため、官能的に飲みにくい。 Conventionally, as a means for opening a lid member without using an opening device such as a bottle opener for a container or the like, a gripping portion such as a pull ring that protrudes from an edge of a part of a skirt wall that is continuous with the top wall of the lid member There is known a container with a lid formed with a score which is a weakening line extending from the base of the gripping part to the skirt wall and further to the top wall.
In the opening of the container body of such a container with a lid, a bead-like protrusion protruding outward in the radial direction of the container body is formed around the opening in order to lock the lid member when the container is closed. (See FIG. 6 of Patent Document 1 below). However, when drinking a beverage using the container body, the protruding portion hits the lips of the user or the like, so it is difficult to drink sensuously.

特許文献１には、このような突状部のない容器本体、すなわち外周面に突出した部分のない容器本体が開示されている。この特許文献１において開示されている蓋付き容器では、金属製の蓋部材の内周面に、容器本体の上縁部（開口部）に嵌合する凹溝を形成した環状の弾性部材を設け、蓋部材の中央部には、蓋付き容器の内外を連通する透孔を形成している。また、蓋部材の外面側には、透孔を閉塞する無着臭性のプラスチックフィルムよりなる封止片が配設されている。   Patent Document 1 discloses a container main body without such a protruding portion, that is, a container main body without a protruding portion on the outer peripheral surface. In the container with a lid disclosed in Patent Document 1, an annular elastic member is provided on the inner peripheral surface of a metal lid member. The annular elastic member has a concave groove that fits into the upper edge (opening) of the container body. In the central part of the lid member, a through hole is formed which communicates the inside and outside of the lidded container. Further, a sealing piece made of an odorless plastic film that closes the through hole is disposed on the outer surface side of the lid member.

このような蓋付き容器は、内容物を容器本体に入れた後、容器内を真空にすることによって、蓋部材を容器本体の開口部に密着せしめている。そして、蓋部材の封止片の外面には、封止片の全面を覆い、剥離時には封止片と一体に剥離する保護シール片が蓋本体に対して剥離自在に貼着されている。
容器本体から蓋部材を開栓するときには、保護シール片を剥離することによって、封止片が剥がれ、これによって、透孔が大気に開放されるため、容器内の真空度が失われて容器本体が開栓されるようにしている。
実用新案登録第３１１６６７３号公報 In such a container with a lid, after the contents are put into the container main body, the inside of the container is evacuated to bring the lid member into close contact with the opening of the container main body. And the protective seal piece which covers the whole surface of a sealing piece and peels integrally with a sealing piece at the time of peeling is stuck on the outer surface of the sealing piece of a cover member so that peeling is possible.
When opening the lid member from the container body, the sealing piece is peeled off by peeling off the protective seal piece, thereby opening the through-hole to the atmosphere, so the degree of vacuum in the container is lost and the container body Is opened.
Utility Model Registration No. 3116673

しかしながら、このように、蓋部材に透孔を形成したことにより、容器内の内容物が封止片や蓋部材の透孔面に接触することになり、品質を維持させるために、封止片の材質に特別な素材を必要としたり、蓋部材の透孔に品質を維持させるための何らかの処理をしなければならない。さらに、容器本体への蓋部材の閉塞力が減圧による吸引力のみであるので、密閉性に対する信頼度を向上させるため、容器本体の上部と蓋部材を覆う熱収縮フィルム（シュリンクフィルム）で覆う必要性もある。   However, since the through-hole is formed in the lid member in this way, the contents in the container come into contact with the sealing piece and the through-hole surface of the lid member, and in order to maintain the quality, the sealing piece A special material is required for the material of the material, or some kind of treatment is required to maintain the quality of the through hole of the lid member. Furthermore, since the closure force of the lid member to the container body is only the suction force due to the reduced pressure, it is necessary to cover the container body with a heat shrink film (shrink film) covering the upper part of the container body and the lid member in order to improve the reliability of the sealing performance. There is also sex.

本発明は、このような事情に鑑みてなされたものであって、容器内を減圧させることによって、容器本体の閉栓時に、蓋部材の閉塞力の信頼度を確実にすることができ、内容物の品質の維持についても、特別な技術を必要とせず、さらには容器本体の厚さを薄くすることができる蓋付き容器を提供することを目的とする。   The present invention has been made in view of such circumstances, and by reducing the pressure inside the container, the reliability of the closing force of the lid member can be ensured when the container body is closed, and the contents The object of the present invention is to provide a lidded container that does not require any special technique and can reduce the thickness of the container body.

本発明の蓋付き容器は、上記目的を達成するために、少なくとも開口部側外周面が該開口部側から底部に向かって半径方向内側に径が漸次減少する容器本体と該容器本体を閉塞する蓋部材とからなる蓋付き容器であって、該蓋部材が金属製の蓋本体と該蓋本体の内面に配設されるライナーとを備え、該蓋本体が、天面壁と、該天面壁の周囲から下方に延びるスカート壁と、該スカート壁の下端の一部から突出する把持部と、該把持部の基端部の両端からスカート壁を上方に延びる一対のスコアを形成してなり、前記蓋本体には前記把持部を除いた前記スカート壁の下端に、外側に湾曲するカール部を形成し、前記蓋本体の天面壁の周縁部には前記開口部の上縁部に当接するライナーを設け、前記スコアは該ライナーの位置まで延びて形成され、前記蓋部材の容器本体への装着時に前記カール部を、半径方向内側に径が漸次減少する前記開口部外周面側に押圧して前記スカート壁の下端の内径を前記開口部外周面の最大外径部より小径に形成し、前記蓋本体を容器本体の開口部に保持するとともに、容器本体の内部を減圧状態に保持した。
上記蓋付き容器の前記天面壁は、前記周縁部、該周縁部から半径方向内方に向かって下方に傾斜して延びる逆円錐台形状部、及び該逆円錐台形状部の内側の円形中央沈降部からなり、該周縁部の内周面に前記ライナーを配設するようにした。 In order to achieve the above object, the lidded container of the present invention closes at least the container body whose outer peripheral surface at the opening side gradually decreases in diameter radially inward from the opening side toward the bottom, and the container body. A lidded container comprising a lid member, the lid member comprising a metal lid body and a liner disposed on the inner surface of the lid body, the lid body comprising a top wall and a top wall A skirt wall extending downward from the periphery, a gripping portion protruding from a part of the lower end of the skirt wall, and a pair of scores extending upward from the both ends of the base end portion of the gripping portion. A curled portion that curves outward is formed at the lower end of the skirt wall excluding the gripping portion on the lid body, and a liner that contacts the upper edge of the opening is formed at the peripheral edge of the top wall of the lid body. The score is formed extending to the position of the liner The curled portion during mounting of the container body of the lid member, the maximum outside by pressing the opening outer circumferential surface whose diameter radially inward to gradually decrease the inner diameter of the lower end of the skirt wall above the opening peripheral surface The lid body was formed in a smaller diameter than the diameter part, the lid body was held in the opening of the container body, and the inside of the container body was held in a reduced pressure state.
The top wall of the lidded container includes the peripheral portion, an inverted truncated cone-shaped portion extending downwardly inward in the radial direction from the peripheral portion, and a circular central settling inside the inverted truncated cone-shaped portion. The liner is arranged on the inner peripheral surface of the peripheral edge.

本発明の蓋付き容器は、少なくとも開口部側外周面が該開口部側から底部に向かって半径方向内側に径が漸次減少する容器本体と該容器本体を閉塞する蓋部材とからなる蓋付き容器であって、該蓋部材が金属製の蓋本体と該蓋本体の内面に配設されるライナーとを備え、該蓋本体が、天面壁と、該天面壁の周囲から下方に延びるスカート壁と、該スカート壁の下端の一部から突出する把持部と、該把持部の基端部の両端からスカート壁を上方に延びる一対のスコアを形成してなり、前記蓋本体には前記把持部を除いた前記スカート壁の下端に、外側に湾曲するカール部を形成し、前記蓋本体の天面壁の周縁部には前記開口部の上縁部に当接するライナーを設け、前記スコアは該ライナーの位置まで延びて形成され、前記蓋部材の容器本体への装着時に前記カール部を前記開口部外周面側に押圧して前記スカート壁の下端の内径を前記開口部外周面の最大外径部より小径に形成し、前記蓋本体を容器本体の開口部に保持するとともに、容器本体の内部を減圧状態に保持したので、蓋付き容器内の直接の減圧と、カール部の減径による直接（外周面に当接）又は間接（外周面に非当接）的な閉栓とによる２重閉栓構造であり、容器本体の確実な閉栓状態を可能にすることができる。
上記蓋付き容器の前記天面壁は、前記周縁部、該周縁部から半径方向内方に向かって下方に傾斜して延びる逆円錐台形状部、及び該逆円錐台形状部の内側の円形中央沈降部からなり、該周縁部の内周面に前記ライナーを配設するようにしたので、蓋部材を容器本体に被せ、内部を減圧させた時に、円形中央沈降部の中央突出部が容器本体の底部側へ窪み、内部の減圧状態が確認でき、蓋部材と容器本体の密着性を確認できる。周縁部に隣接して下方に傾斜して延びる逆円錐台形状部を形成したので、周縁部の内側が凹形状となり、ライナーの配設を安定にし、十分な量を確保することができ、しかも、密閉性を向上させることができる。 The lidded container of the present invention is a lidded container comprising at least a container body whose outer diameter on the opening side gradually decreases radially inward from the opening side toward the bottom, and a lid member that closes the container body. The lid member includes a metal lid body and a liner disposed on the inner surface of the lid body, and the lid body includes a top wall and a skirt wall extending downward from the periphery of the top wall. A grip part protruding from a part of the lower end of the skirt wall and a pair of scores extending upward from the both ends of the base end part of the grip part to the skirt wall. A curled portion that curves outward is formed at the lower end of the removed skirt wall, and a liner that abuts the upper edge of the opening is provided at the peripheral edge of the top wall of the lid body. Extending to a position, the lid member to the container body At the time of wearing, the curled portion is pressed toward the outer peripheral surface side of the opening to form an inner diameter of the lower end of the skirt wall smaller than a maximum outer diameter portion of the outer peripheral surface of the opening, and the lid main body is used as an opening of the container main body. While holding the inside of the container body in a reduced pressure state, direct pressure reduction in the lidded container and direct (contact with the outer peripheral surface) or indirect (non-contact with the outer peripheral surface) by reducing the diameter of the curled portion It is a double closure structure with a typical closure, and a reliable closure state of the container body can be made possible.
The top wall of the lidded container includes the peripheral portion, an inverted truncated cone-shaped portion extending downwardly inward in the radial direction from the peripheral portion, and a circular central settling inside the inverted truncated cone-shaped portion. Since the liner is disposed on the inner peripheral surface of the peripheral portion, when the lid member is put on the container body and the inside is decompressed, the central protrusion of the circular central settling portion is It dents to the bottom part side, the internal pressure reduction state can be confirmed, and the adhesion between the lid member and the container body can be confirmed. Since the inverted frustoconical shape that extends downward and adjacent to the periphery is formed, the inside of the periphery becomes a concave shape, the arrangement of the liner can be stabilized, and a sufficient amount can be secured. , Sealing performance can be improved.

以下、本発明の実施形態の蓋付き容器について、図面を参照しながら説明する。
図１は、本発明による蓋付き容器の一例を示す正面図、図２はその側面図、図３は図２Ｘ−Ｘ線方向における断面図である。
本発明に係る蓋付き容器１は、容器本体２と金属製の蓋部材３とを備えている。容器本体２は、本実施形態ではガラス製容器であるが合成樹脂で成形したものであってもよい。この容器本体２の特徴とするところは、少なくとも容器本体２の開口部５側の外周面６が開口部５側から底部７に向かって半径方向内側に径が漸次減少していることである。 Hereinafter, a container with a lid according to an embodiment of the present invention will be described with reference to the drawings.
1 is a front view showing an example of a lidded container according to the present invention, FIG. 2 is a side view thereof, and FIG. 3 is a cross-sectional view in the direction of FIG. 2X-X.
A container 1 with a lid according to the present invention includes a container body 2 and a metal lid member 3. The container body 2 is a glass container in this embodiment, but may be formed of a synthetic resin. The container body 2 is characterized in that at least the outer peripheral surface 6 on the opening 5 side of the container body 2 gradually decreases in diameter radially inward from the opening 5 side toward the bottom 7.

径が漸次減少とは、図３に示すように、容器本体２の外周面の開口部５から底部７までの全体にわたって、径が漸次減少するものが含まれるが、少なくとも開口部５側における外周面６であって、蓋部材３で覆われる部分が漸次減少していることが必要である。したがって、開口部５側以外の部分は、凹凸があってもよく、直線形状であってもよく、容器本体の下側の形状を、円筒形、球形、四角形等の形状にしてもよい。さらに、開口部５側外周面６の形状は、径が漸次減少していれば、外周面６の断面形状の稜線は、直線形状であってもよく、弧を描いた流線形状であってもよい。   As shown in FIG. 3, the gradual decrease in diameter includes those in which the diameter gradually decreases from the opening 5 to the bottom 7 of the outer peripheral surface of the container body 2, but at least the outer periphery on the opening 5 side. It is necessary that the portion of the surface 6 covered with the lid member 3 is gradually reduced. Therefore, the portion other than the opening 5 side may be uneven or may be linear, and the shape of the lower side of the container body may be a cylindrical shape, a spherical shape, a rectangular shape, or the like. Furthermore, if the diameter of the outer peripheral surface 6 on the opening 5 side is gradually reduced, the ridgeline of the cross-sectional shape of the outer peripheral surface 6 may be a straight line shape or a streamline shape depicting an arc. Also good.

次に、このようなビード状の突部がない開口部５に、容器本体２を閉塞する蓋部材３について説明する。
図４のＡ〜Ｃは、容器本体２に装着する前の蓋部材３を示し、蓋部材３は蓋本体８とライナー９とから構成される。蓋本体８は、アルミニウム基合金薄板が最も好ましいが、クロム酸処理鋼薄板、ブリキ薄板等の適宜金属薄板をプレス等により絞り成形することにより形成することも可能である。この蓋本体８は、円板形状の天面壁１１とこの天面壁１１の周縁部から実質的に垂下する円筒状のスカート壁１２とを備えている。スカート壁１２の内径は、容器本体２の開口部５の最大外径部Ｐ（図５参照）の外径とほぼ同じ大きさを有している。 Next, the lid member 3 that closes the container body 2 in the opening 5 having no bead-shaped protrusion will be described.
4A to 4C show the lid member 3 before being attached to the container main body 2, and the lid member 3 includes a lid main body 8 and a liner 9. The lid body 8 is most preferably an aluminum-based alloy thin plate, but can also be formed by drawing a suitable metal thin plate such as a chromic acid-treated steel thin plate or a tin thin plate with a press or the like. The lid body 8 includes a disk-shaped top wall 11 and a cylindrical skirt wall 12 that substantially hangs down from the peripheral edge of the top wall 11. The inner diameter of the skirt wall 12 has substantially the same size as the outer diameter of the maximum outer diameter portion P (see FIG. 5) of the opening 5 of the container body 2.

スカート壁１２の下端には、該スカート壁１２の下縁部の一部に連結し、その端縁よりさらに下側へ突出するように突部１４を形成し、突部１４には、把持部であるプルリング１５が連結されている。プルリング１５は、突部１４から下方に、容器本体２の外周面６にほぼ沿うようにして延在させている（図５参照）。
突部１４のスカート壁１２への付根には、比較的小さな切り欠き部１６が形成されている。切り欠き部１６は、突部１４の上端部で最深部となり、この切り欠き部１６の最深部には、スカート壁１２を高さ方向に横切り、天面壁１１まで延びる一対のスコア１８が形成されている。このスコア１８は一般に薄肉部から成り、スコア１８が形成される位置は、少なくともライナー９の縁部を越える位置まで形成されている。
スカート壁１２の突部１４がある部分を除いて、スカート壁１２の下端には外側に向かってほぼ円形状に湾曲されたカール部１９が形成されている。 The lower end of the skirt wall 12 is connected to a part of the lower edge portion of the skirt wall 12, and a protrusion 14 is formed so as to protrude further downward from the end edge. The pull ring 15 is connected. The pull ring 15 extends downward from the protrusion 14 so as to be substantially along the outer peripheral surface 6 of the container body 2 (see FIG. 5).
A relatively small notch 16 is formed at the base of the protrusion 14 to the skirt wall 12. The notch 16 is the deepest part at the upper end of the protrusion 14, and a pair of scores 18 that extend across the skirt wall 12 in the height direction and extend to the top wall 11 are formed at the deepest part of the notch 16. ing. The score 18 is generally formed of a thin-walled portion, and the position where the score 18 is formed is formed at least up to a position exceeding the edge of the liner 9.
A curl portion 19 that is curved in a substantially circular shape toward the outside is formed at the lower end of the skirt wall 12 except for the portion where the protrusion 14 of the skirt wall 12 is provided.

図３及び図５を参照にして、蓋本体８の天面壁１１は、外側から順に、内方に延びる環状周縁部２１、該環状周縁部２１から天面壁１１の半径方向内方に向かって下方に傾斜して延びる逆円錐台形状部２２、及び該逆円錐台形状部２２の内側の円形中央沈降部２３からなる。
環状周縁部２１の内周面には上述したライナー９が装着されている。ライナー９の材料は、ポリ塩化ビニル、ポリウレタンなどの合成樹脂が用いられる。ライナー９は、環状周縁部２１の内周面に充填されるようにして配設されている（図４のＡ参照）。このライナー９は、環状周縁部２１の内周面に塗布された金属塗料などによって接着される。円形中央沈降部２３の中央突出部２３ｂは、円形中央沈降部２３の周縁平坦部２３ａから上方に向かって僅かに膨張するような形状で突出されている。
図５に示すように、容器本体の上縁部は内側に水平部５ａを形成し、その外周側は水平部５ａから下方へ半径方向外側に向かって拡がる湾曲面５ｂを形成している。 With reference to FIGS. 3 and 5, the top wall 11 of the lid body 8 is, in order from the outside, an annular peripheral edge 21 extending inward, and downward from the annular peripheral edge 21 toward the radially inner side of the top wall 11. And an inverted frustoconical portion 22 extending in a slanted manner and a circular central settling portion 23 inside the inverted frustoconical portion 22.
The liner 9 described above is attached to the inner peripheral surface of the annular peripheral edge 21. The material of the liner 9 is a synthetic resin such as polyvinyl chloride or polyurethane. The liner 9 is disposed so as to fill the inner peripheral surface of the annular peripheral edge 21 (see A in FIG. 4). The liner 9 is bonded to the inner peripheral surface of the annular peripheral edge portion 21 by a metal paint applied on the inner peripheral surface. The central projecting portion 23b of the circular central sedimentation portion 23 projects in a shape that slightly expands upward from the peripheral flat portion 23a of the circular central sedimentation portion 23.
As shown in FIG. 5, the upper edge part of the container body forms a horizontal part 5a on the inner side, and the outer peripheral side forms a curved surface 5b that expands radially outward from the horizontal part 5a.

このような構成である蓋付き容器１は、容器本体２が以下のようにして閉栓される。
先ず、容器本体２の内部に、例えば酒などの内容物を入れる。内容物の温度は５０〜６０℃であり、内容物の充填量は、開口部５までいれることなく、減圧できる程度の空間を空ける必要がある。次に、容器本体２の開口部５に蓋部材３が装着される。この際、蓋部材３の環状周縁部２１の内周面に配設したライナー９が、容器本体２の開口部５における水平部５ａ上に載置される。このとき、図示しない閉栓治具によって、蓋部材３の天面壁１１を押圧するとともにカール部１９を蓋本体８の半径方向内側へ押圧する。ライナー９は弾性を有するので、図５に示す容器本体２の上縁部である水平部５ａ及び湾曲面５ｂ、さらには水平部５ａから開口部５の内周面側と密着する。
蓋部材３のカール部１９は、押圧用治具によって内側に減径し、容器本体２の開口部５における外周面の最大外径部Ｐの径よりも、蓋部材３のスカート壁１２の下端部であるカール部１９の内径が小さくなるように絞り形成する。絞り成形については、絞り部分であるカール部１９の内周面が、容器本体２の外周面を押圧しないで接する程度の軽度のかしめでよい。ただし、カール部１９が外周面を押圧することもできるし、隙間を空けてもよい。 In the lidded container 1 having such a configuration, the container body 2 is closed as follows.
First, contents such as liquor are placed in the container body 2. The temperature of the contents is 50 to 60 ° C., and the filling amount of the contents needs to leave a space where pressure can be reduced without entering the opening 5. Next, the lid member 3 is attached to the opening 5 of the container body 2. At this time, the liner 9 disposed on the inner peripheral surface of the annular peripheral edge portion 21 of the lid member 3 is placed on the horizontal portion 5 a in the opening 5 of the container body 2. At this time, the top surface wall 11 of the lid member 3 is pressed by a closing jig (not shown) and the curled portion 19 is pressed radially inward of the lid body 8. Since the liner 9 has elasticity, it is in close contact with the horizontal portion 5a and the curved surface 5b, which are the upper edge portions of the container body 2 shown in FIG. 5, and further, from the horizontal portion 5a to the inner peripheral surface side of the opening 5.
The curled portion 19 of the lid member 3 is reduced in diameter by a pressing jig, and the lower end of the skirt wall 12 of the lid member 3 is smaller than the diameter of the maximum outer diameter portion P of the outer peripheral surface of the opening 5 of the container body 2. The curled portion 19 as a portion is formed so as to have a small inner diameter. For drawing, the caulking portion 19 that is the drawing portion may be slightly caulked so that the inner peripheral surface of the curled portion 19 contacts the outer peripheral surface of the container body 2 without pressing. However, the curled portion 19 may press the outer peripheral surface, or a gap may be formed.

一方、内容物の温度は、５０〜６０℃であるので、常温よりも高く自然冷却によって、蓋付き容器１の内部が減圧される。この減圧により、蓋部材３が容器本体２の内部側へ吸引されて、ライナー９が容器本体２の水平部５ａ及び湾曲面５ｂなどの容器本体２に接している部分が密着し、蓋付き容器１の内部の密閉性を図ることができる。この内部空間の減圧により、蓋部材３の天面壁１１が吸引されて、その円形中央沈降部２３に形成されている中央突出部２３ｂが容器本体２の底部７側に窪む（図５中の二点鎖線参照）。この中央突出部２３ｂが、窪むことによって、内部の減圧を確認することができ、さらには、蓋部材３と容器本体２の密着性を確認できる。   On the other hand, since the temperature of the contents is 50 to 60 ° C., the inside of the lidded container 1 is decompressed by natural cooling higher than normal temperature. By this decompression, the lid member 3 is sucked into the container body 2 and the portions where the liner 9 is in contact with the container body 2 such as the horizontal portion 5a and the curved surface 5b of the container body 2 are brought into close contact with each other. 1 can be sealed. Due to the decompression of the internal space, the top wall 11 of the lid member 3 is sucked, and the central projecting portion 23b formed in the circular central sedimentation portion 23 is recessed toward the bottom 7 side of the container body 2 (in FIG. 5). (See the two-dot chain line). When the central projecting portion 23b is depressed, internal pressure reduction can be confirmed, and furthermore, the adhesion between the lid member 3 and the container body 2 can be confirmed.

このようにして、容器本体２に蓋部材３を装着することができる。したがって、容器本体２の開口部５にビードが形成されていなくとも、従来の既存の設備で、容器本体２に蓋部材３を閉栓することができる。
上述したように、蓋付き容器１の内部は、減圧されてライナー９が密閉性を保持しているが、本実施形態では、さらに、容器本体２の開口部５における外周面の最大外径部Ｐの径よりも、蓋部材３のスカート壁１２の下端側の内径が小さくなるように、形成されている。したがって、通常の取り扱いによる程度の力が作用しても、最大外径部Ｐを乗り越えることができず、蓋部材３が容器本体２から外れることがない。 In this way, the lid member 3 can be attached to the container body 2. Therefore, even if the bead is not formed in the opening 5 of the container main body 2, the lid member 3 can be closed on the container main body 2 with conventional existing equipment.
As described above, the inside of the lidded container 1 is decompressed and the liner 9 maintains hermeticity, but in this embodiment, the maximum outer diameter portion of the outer peripheral surface of the opening 5 of the container body 2 is further increased. It is formed so that the inner diameter of the lower end side of the skirt wall 12 of the lid member 3 is smaller than the diameter of P. Therefore, even if a force of a level due to normal handling is applied, the maximum outer diameter portion P cannot be overcome and the lid member 3 is not detached from the container body 2.

このように、蓋部材３の容器本体１への閉栓性についても、減圧とスカート壁１２の下端部の軽い絞りによって、閉栓した２重構造であるので、確実な閉栓状態が可能になった。スカート壁１２の周囲全体が開口部５の外周部の全体を一体的に覆っているので、外力を受けても、通常の範囲内の外力であれば、スカート壁１２が外側に開くことがなく、蓋部材３が開口部５から離脱することがない。
このような、蓋付き容器１については、タンパーエビデント性を向上させるため、シュリンクフィルムを蓋部材３及び容器本体２の上部、若しくは全体にわたって覆うようにしても良い。 As described above, the closure of the lid member 3 to the container main body 1 has a double structure in which the lid member 3 is closed by decompression and a light restriction at the lower end of the skirt wall 12, so that a reliable closure state is possible. Since the entire periphery of the skirt wall 12 integrally covers the entire outer periphery of the opening 5, even if an external force is applied, the skirt wall 12 does not open outward if the external force is within a normal range. The lid member 3 is not detached from the opening 5.
About such a container 1 with a lid | cover, you may make it cover a shrink film over the upper part of the cover member 3 and the container main body 2, or the whole in order to improve tamper evidence property.

このような構成により、ユーザが容器本体２から蓋部材３を開栓するときは、プルリング１５を指に差し込んで、プルリング１５をスカート壁１２の上方側へ引っ張って切断する。この際、まず、プルリング１５を蓋部材３の径方向外方に引っ張り、スカート壁１２のスコア１８を引き裂いた後、プルリング１５を上方に引き上げて、天面壁１１側の環状周縁部２１まで形成されたスコア１８を更に引き裂く。これにより、プルリング１５の突部１４の裏面に接着されているライナー９部分が、上方へめくり上がり、この部分におけるライナー９の密閉性が失われ、大気が容器本体２内に浸入する。したがって、スコア１８を形成する位置は、ライナー９がめくり上がる位置まで形成することが好ましい。   With such a configuration, when the user opens the lid member 3 from the container body 2, the pull ring 15 is inserted into a finger, and the pull ring 15 is pulled upward from the skirt wall 12 to be cut. At this time, first, the pull ring 15 is pulled outward in the radial direction of the lid member 3, the score 18 of the skirt wall 12 is torn, and then the pull ring 15 is pulled upward to form the annular peripheral edge 21 on the top wall 11 side. Tear score 18 further. As a result, the liner 9 portion bonded to the back surface of the protrusion 14 of the pull ring 15 is turned upward, and the sealing property of the liner 9 at this portion is lost, and the air enters the container body 2. Therefore, it is preferable to form the position where the score 18 is formed up to the position where the liner 9 is turned up.

大気が容器本体２内に浸入すると、減圧による蓋部材３の天面壁１１への吸引力が失われる。一方、プルリング１５を引いて、スコア１８が引き裂かれることによって、スカート壁１２は、環状形状でなくなり、特にスカート壁１２の下端側で、プルリング１５の両端部から切り離された部分が大きく外側へ拡がることができる。したがって、カール部１９は開口部５の最大外径部Ｐを乗り越えることができ、蓋部材３は容器本体２の開口部５から解き放され、容器本体２は容易に開栓することができる。
このように本実施形態では、容器本体１の開口部５にビード状の突部のない容器本体２であっても、蓋部材３をその開口部５に保持することができるようになった。そのため、突部のない滑らかな形状をした開口部５にユーザの唇を当てて飲料を飲むことができ、ユーザは官能的に飲みやすく、口当たりが良い容器となる。内容物の品質維持についても、通常の蓋部材とかわりがないので、既存の蓋部材の品質維持の技術がそのまま適用することができる。 When the air enters the container body 2, the suction force to the top wall 11 of the lid member 3 due to the reduced pressure is lost. On the other hand, when the pull ring 15 is pulled and the score 18 is torn, the skirt wall 12 does not have an annular shape, and particularly, at the lower end side of the skirt wall 12, the portions separated from the both ends of the pull ring 15 greatly expand outward. be able to. Therefore, the curled portion 19 can get over the maximum outer diameter portion P of the opening 5, the lid member 3 is released from the opening 5 of the container main body 2, and the container main body 2 can be easily opened.
Thus, in this embodiment, even if it is the container main body 2 without the bead-shaped protrusion in the opening part 5 of the container main body 1, the cover member 3 can be hold | maintained in the opening part 5. FIG. Therefore, it is possible to drink a beverage by applying the user's lips to the smooth opening portion 5 having no protrusions, and the user is sensually easy to drink and has a good mouthfeel. Since the quality of the contents is not changed from that of a normal lid member, the existing technology for maintaining the quality of the lid member can be applied as it is.

従来の容器本体では、開口部に形成されているビート状の突部に巻き込むようにしてかしめを形成したので、容器本体の材質を厚くする必要があったが、本実施形態では、カール部１９の絞り部分が、容器本体２の外周面に当接しないように、若しくは当接しても圧力を加えないようにしたので、絞りを形成しても容器本体２に負荷がかからない。よって、本実施形態のように、容器本体２がガラス製である場合は、容器本体２の肉厚を薄くすることができる効果がある。これについては、合成樹脂製の容器本体にも同様のことがいえる。容器本体を薄くしたような場合は、家庭で使用されている市販のコップのように、意匠性に優れた形状にすることができるので、そのまま再利用が可能となり、リサイクルの手間を省略することもできる。   In the conventional container main body, since the caulking is formed so as to be wound around the bead-shaped protrusion formed in the opening, it is necessary to increase the material of the container main body. Since the squeezed portion is not in contact with the outer peripheral surface of the container main body 2 or no pressure is applied even if the squeezed portion is contacted, no load is applied to the container main body 2 even if the squeezed portion is formed. Therefore, when the container main body 2 is made of glass as in this embodiment, there is an effect that the thickness of the container main body 2 can be reduced. The same applies to the container body made of synthetic resin. When the container body is thin, it can be made into a shape with excellent design like a commercially available cup used at home, so it can be reused as it is, and the recycling effort is omitted. You can also.

なお、本実施形態では、容器本体２の開口部５における最大外径Ｐの径よりも、スカート壁１２の下端にあるカール部１９の内径が小さくなる程度の軽いかしめを形成するようにし、また、蓋本体８の材料についても、円形中央沈降部２３が減圧で窪むような比較的軟らかい材料を使用した。また、スコア１８については、プルリング１５を形成した部分の両端に一対形成しただけである。ただし、カール部１９の絞り量を大きくしたり、蓋本体８の材料を比較的硬い材料で形成したりして、蓋部材３が外しづらくなったような場合は、スコア１８を形成する本数をさらに増やしても良い。例えば、プルリング１５の中央線から左右周方向へ９０度、離した位置にさらにスコアを形成するとよい。   In the present embodiment, a caulking that is light enough that the inner diameter of the curled portion 19 at the lower end of the skirt wall 12 is smaller than the diameter of the maximum outer diameter P in the opening 5 of the container body 2 is formed. As for the material of the lid body 8, a relatively soft material in which the circular central settling part 23 is depressed by reduced pressure was used. For the score 18, only a pair is formed at both ends of the portion where the pull ring 15 is formed. However, if it is difficult to remove the lid member 3 by increasing the aperture amount of the curled portion 19 or by forming the lid body 8 from a relatively hard material, the number of the score 18 is set. It may be increased further. For example, a score may be further formed at a position 90 degrees away from the center line of the pull ring 15 in the left-right circumferential direction.

以上、本発明を実施形態に基づいて添付図面を参照しながら詳細に説明したが、本発明は上記実施形態に限定されるものではなく、本発明の範囲を逸脱することなく、更に他の変形あるいは修正が可能である。
例えば、上記実施形態では、蓋部材３の天面壁３の中央部に円形中央沈降部２３を形成したが、この円形中央部沈降部２３を省略して逆円錐台形状部２２の周縁平坦部２３ａと面一形状にしてもよい。 The present invention has been described in detail based on the embodiments with reference to the accompanying drawings. However, the present invention is not limited to the above-described embodiments, and other modifications can be made without departing from the scope of the present invention. Or it can be modified.
For example, in the above embodiment, the circular central sedimentation portion 23 is formed in the central portion of the top wall 3 of the lid member 3, but the circular central sedimentation portion 23 is omitted and the peripheral flat portion 23 a of the inverted frustoconical shape portion 22.
