【００１１】
図５（ａ）に示す本実施形態の飲み口開閉用小蓋付キャップ（１００）を装着したカップ状容器（２００）は、内容物を飲むために容器を開封するときに、キャップの前方の飲み口開閉用小蓋（１５０）の周壁（１４０）下端に指を掛けて上方後方へ引き上げると、飲み口開閉用小蓋（１５０）が、図１（ａ）に示すキャップ（１００）の中央天板（１２０）のスナップヒンジ機構部（１３０）の左右のスリット（１３１，１３２）と左右の開閉用スリット（１０１，１０２）間に設けた前後方向の中心位置の線状薄肉ヒンジ（１２４と１２６）を支線として回転し後方へ折れ曲がって、図５（ｂ）に示すように、飲み口開閉用小蓋（１５０）が開くが、スナップヒンジ機構部の前方側傾斜板（１３３）と中央水平板（１３４）間及び後方側傾斜板（１３５）と中央水平板（１３４）間に設けられた線状薄肉ヒンジ（１３７，１３９）も折れ曲がり、中央水平板が水平状態から垂直状態へ移行し、このときにバネ力が発生するため、ある傾斜角度から飲み口開閉用小蓋が後方へ自動的に開き、そして開き切った状態で維持される。飲み口開閉用小蓋を開いたのち、容器を封止している封止フィルムの外周縁部又はつまみ片を指で摘んで剥離又は破断して開口し、この開口した飲み口から、内容物をキャップが付いたまま飲むことができる。なお、容器を再封止するときは、開いている飲み口開閉用小蓋の周縁部天板の前方部に指を当てて、飲み口開閉用小蓋を前方へ引っ張ると、前述のキャップの中央天板の線状薄肉ヒンジを支線として前方へ回転し、飲み口開閉用小蓋が閉じてくるが、折れ曲がった状態のスナップヒンジ機構部の前方側傾斜板と中央水平板間及び後方側傾斜板と中央水平板間に設けられた線状薄肉ヒンジが開いた状態となり、垂直状態だった中央水平板が水平状態へ移行し、このときにバネ力が発生するため、ある傾斜角度から飲み口開閉用小蓋が前方へ自動的に閉じ、そして閉じた状態で維持される。
【００１２】
なお、本実施形態の飲み口開閉用小蓋付キャップを装着したカップ状容器は、容器を積み重ねたときに、図６（ｂ）に示すように、上方のカップ状容器（２００）の周壁（２１０）下端が、下方の容器の飲み口開閉用小蓋付キャップ（１００）の図１に示す前方の積重ね用リブ（１２１）と後方の積重ね用リブ（１２２）との間に入って、中央天板（１２０）に当接するように製品設計するものである。

It is explanatory drawing.
[0009]
As shown in FIGS. 1 (a) and 1 (b), the structure of the cap with a lid for opening and closing the mouthpiece (100) of one embodiment is provided with a peripheral top plate (110) at the upper end of the peripheral wall (140), A central top plate (120) whose outer peripheral edge portion has a bowl-like shape is formed on the inner upper side of the peripheral edge top plate, and the peripheral edge top plate is respectively provided from two predetermined lower end positions on the left and right sides in front of the peripheral wall. The left and right open / close slits (101, 102) from the center position in the front-rear direction of the central top plate to the rear vicinity position are provided, and a rectangular snap hinge mechanism portion (130) is provided at the center position of the central top plate. As shown in FIGS. 3A to 3D, the snap hinge mechanism (130) is provided with slits (131, 132) parallel in the front-rear direction on both left and right sides, and the front between the left and right slits. Providing a front-side inclined plate (133) that descends backward at the position A rearwardly inclined rear plate (135) is provided at the rear position between the left and right slits, and a central horizontal plate (134) is provided at the front end of the rearwardly inclined plate and the rear end of the front inclined plate, and the lower surface is shown in FIG. Connected through linear thin-walled hinges (139, 137) formed by providing cuts (138, 136), as shown in FIGS. 1 (a) and (b), the central top plate (120) in the front-rear direction At the center position, linear thin-walled hinges (124, 126) extending from the left and right slits (131, 132) of the snap hinge mechanism (130) to the left and right opening / closing slits (101, 102) are provided at the front position. A mouth opening / closing lid (150) is formed, and a stacking rib (121) is projected along the outer periphery of the upper surface of the central top plate of the mouth opening / closing lid so that the opening / closing slit of the lower surface is opened. Figure 1 (b) along the outer periphery inside 2 is suspended, and an engagement rib (128) with a cup-shaped container is provided continuously or intermittently on the inner peripheral surface of the peripheral wall (140), and a drinking cap opening / closing small lid (150 ) And a stacking rib (122) projecting along the outer periphery at the front position on the upper surface of the central top plate (120) behind the center top plate (120), and abutting along the outer periphery inside the opening and closing slits (101, 102) on the lower surface The rib (128) is suspended, and the occlusal rib (142) with the cup-shaped container is provided continuously or intermittently on the inner peripheral surface of the peripheral wall (140). In addition, when the above-mentioned contact rib (127,128) is attached to the cup-shaped container (200) as shown in FIG. 5 (a), the lower end of the contact rib is the upper surface of the sealing film (300). In addition, as shown in FIG. 6A, when the caps (100) are stacked, the lower end of the upper cap abutment rib (128) is the center top plate of the lower cap ( 120), the product is designed so as to form a gap in which the upper cap and the lower cap can be separated.
[0010]
In addition, the container to which the cap (100) with a lid for opening and closing the mouthpiece according to the present embodiment is attached is formed at the upper end of the peripheral wall (210) having a circular horizontal cross section as shown in FIG. 4 or FIG. A cup-shaped container (200) having a flange (220), which is filled with contents and then heat-sealed so that the sealing film (300) can be peeled off from the upper surface of the flange and sealed. The sealing film is provided with an opening knob piece as necessary.
[0011]
The cup-shaped container (200) equipped with the cap (100) with a lid for opening and closing the mouthpiece of the present embodiment shown in FIG. 5 (a) is located at the front of the cap when the container is opened to drink the contents. When a finger is put on the lower end of the peripheral wall (140) of the small lid for opening and closing the mouthpiece (150) and pulled up upward and rearward, the small lid for opening and closing the mouthpiece (150) becomes the center of the cap (100) shown in FIG. A linear thin-walled hinge (124 and center) in the front-rear direction provided between the left and right slits (131, 132) and the left and right slits (101, 102) of the snap hinge mechanism (130) of the top plate (120). 126) is rotated as a branch line and bent backward, and as shown in FIG. 5 (b), the small lid for opening and closing the mouthpiece (150) opens, but the front inclined plate (133) of the snap hinge mechanism part and the central horizontal Between plates (134) and rear side The linear thin-walled hinges (137, 139) provided between the swash plate (135) and the central horizontal plate (134) are also bent, and the central horizontal plate shifts from the horizontal state to the vertical state, and a spring force is generated at this time. Therefore, the small lid for opening and closing the drinking mouth automatically opens backward from a certain inclination angle, and is maintained in the fully opened state. After opening the small lid for opening and closing the mouthpiece, the outer peripheral edge or knob of the sealing film sealing the container is picked with a finger and peeled or broken to open the contents. You can drink with the cap on. When resealing the container, put your finger on the front part of the peripheral top of the small lid for opening and closing the mouthpiece and pull the front lid for opening and closing the mouth. Rotate forward with the thin hinge on the central top plate as a branch line, and the small lid for opening and closing the drinking mouth closes, but the snap hinge mechanism part in the bent state is tilted between the front inclined plate and the central horizontal plate and the rear inclined Since the linear thin-walled hinge provided between the plate and the central horizontal plate is in an open state, the central horizontal plate that has been in the vertical state shifts to the horizontal state, and a spring force is generated at this time. The small lid for opening and closing automatically closes forward and is kept closed.
[0012]
In addition, the cup-shaped container equipped with the cap with a small lid for opening and closing the mouthpiece of the present embodiment has a peripheral wall (200) of the upper cup-shaped container (200) as shown in FIG. 210) The lower end is inserted between the front stacking rib (121) and the rear stacking rib (122) shown in FIG. The product is designed to come into contact with the top plate (120).
[0013]
【The invention's effect】
The cap with a small lid for opening and closing the mouthpiece of the present invention is to be attached to a cup-shaped container that is filled with beverage contents and heat-sealed so that the sealing film can be peeled off and sealed to the upper flange. The cap has a small lid for opening and closing the mouth opening that is opened and closed by a snap hinge mechanism, and the mouth does not become clogged when drinking the contents from the opened mouth opening, so that the contents are easy to drink.
[0014]
In addition, the cap with a small lid for opening and closing the drinking mouth of the present invention can be provided with stacking ribs protruding in front and rear of the top plate, so that the cap and the cap can be stacked or the container and the container can be stacked.
