【発明の詳細な説明】
この発明は、有底筒状の紙容器に内容物を入れたのち、
これの開口上面に上蓋を装填固着する方法に改良を加え
たものである。[Detailed Description of the Invention] This invention provides a method for placing contents in a cylindrical paper container with a bottom.
This is an improved method for loading and fixing the top cover onto the top surface of the opening.
最近は、アルミニウム缶が大量に出回つているが、更に
進めてアルミニウム缶に代わる紙容器が出現すれば、製
造コストが安くつくだろうし、使用後の処理も簡単に焼
却できて便利である。Recently, large quantities of aluminum cans have been on the market, but if paper containers were to emerge to replace aluminum cans, manufacturing costs would be lower, and disposal after use would be convenient as they could be easily incinerated.
そのような目的の下に種々の紙容器が提案されているが
、いずれも上蓋装着部の気密性が欠けるところに問題が
あつた。それは、上蓋を容器本体の開口周縁部に外嵌す

とにより、容器本体と上蓋との全周に亘る気密性を確実
にし、以つてアルミニウム缶にも代わる紙容器を得よう
とするものである。Various paper containers have been proposed for this purpose, but all of them have a problem in that the top lid mounting portion lacks airtightness. This is because the top lid is either fitted onto the periphery of the opening of the container body or is glued by rolling it outward, and it is not possible to firmly press the periphery of the top lid and the periphery of the opening of the container body together from the outside. . Furthermore, since the peripheral edge of the top lid protrudes outside the container body, it is easily damaged by contact with other objects. Focusing on this fact, the present invention has been developed by inserting a top lid with a flange curved inwardly into the container body from the top of the opening, and applying the outer circumferential surface of the flange to the inner surface of the top end of the container body from the inside. The purpose is to ensure airtightness over the entire circumference between the container body and the top lid by strongly pressing and adhering, thereby creating a paper container that can replace aluminum cans.
以上、この発明の実施例を図面に基づき説明する。The embodiments of this invention will be described above based on the drawings.
まず、第１図において、１はいずれも紙製の胴２と底蓋
３とからなる有底円笥状の紙容器本体である。First, in FIG. 1, reference numeral 1 denotes a paper container body in the shape of a round cup with a bottom, consisting of a body 2 and a bottom lid 3, both of which are made of paper.

明しよう。This disk 8 is divided into four equal parts in the circumferential direction, and each divided portion 8a can be displaced radially inward and outward with respect to the center of the disk,
It is supported by a support frame 9 that moves up and down. An intake hole 10 connected to an air pump (not shown) is provided through the lower bottom surface of each divided portion 8a, and a heater 11 is built in near the outer peripheral surface of each divided portion 8a. Furthermore, a mechanism is installed inside the support frame 9 to forcibly displace the divided portion 8a simultaneously in the inward and outward directions using means such as an air cylinder, and the support frame 9 itself is driven to move up and down as well as to rotate around the vertical axis. have the means to do so. Next, the process of loading and fixing the top lid 6 onto the opening top surface of the paper container main body 1 by using the above-mentioned members and operating the above-mentioned device will be explained in order.
まず、紙容器本体１に液体などの内容物１２を充填して

分割部分８ａ，８ａ間の間隙に相当する箇所を圧接し、
同様にして両プラスチツク膜４，７同士の熱溶着を図る
。First, the paper container body 1 is filled with contents 12 such as liquid and placed under the disk 8. Then, the upper surface of the upper lid 6 is suctioned and held by the lower surface of the disk 8 by vacuuming. This is the first
This is the state shown in Figure A. From this state, the support frame 9 is lowered so that the upper lid 6
Insert the top lid 6 into the inner surface of the upper end of the container body 1 until the flange 6a of the lid 6 is deeply recessed. Next, each divided portion 8a of the disk 8 is forcibly displaced outward (the opening state in Figure 2).
, press the flange 6a from the inside with its arcuate outer circumferential surface, and press the plastic film 7 on the outer circumferential surface of the flange to the paper container main body 1.
The plastic film 4 and the plastic film 7 are pressed together and heated with a heater 11 to thermally weld the plastic films 4 and 7 together. This is the first
This is the state shown in the figure. Next, after the divided portion 8a is displaced inwardly and the support frame 9 is turned around the vertical axis by 45 degrees, the divided portion 8a is again displaced by an external force as shown in FIG. Pressure-welding the parts corresponding to the gaps between the adjacent divided parts 8a, 8a left in the pressure-welding process,
In the same manner, both plastic films 4 and 7 are thermally welded together.
なお、各分割部分８ａでフランジ６ａを内から外方へ押
圧する際にして、紙容器本体１の上端部外周に円環状の
外枠１３を必要に応じて添接しておけば、フランジ６ａ
の押圧力をより強力にできる。Note that when pressing the flange 6a from the inside to the outside with each divided portion 8a, if an annular outer frame 13 is attached to the outer periphery of the upper end of the paper container main body 1 as necessary, the flange 6a
The pressing force can be made stronger.
最後の仕上げとして、円盤８を内力に変泣させて、元の
状態に上昇復帰させる。As a final touch, the disk 8 is made to cry by internal force and returns to its original state.
そして、第１図ハに示すように、前記フランジ６ａより
上方に突出する紙容器本体１の上端周縁部分を内方に折

分は、第４図に示すように内巻きカーリングしてもよい
。Then, as shown in FIG. 1C, the entire process of loading the top lid is completed by folding inward the upper edge portion of the paper container body 1 that protrudes upward from the flange 6a and bonding it to the inner peripheral surface of the flange. Complete. The upper edge portion of the paper container body 1 may be curled inward as shown in FIG.
また、底蓋３は上記の手段と同様にして装填してもよい

１２でも確実に気密を保持して液洩れなく収容できる紙
容器を得ることができるに至つた。Further, the bottom lid 3 may be loaded in the same manner as the above-mentioned means, but since the processing is carried out in a state where the contents 12 are not filled, any loading means can be employed. Further, in the above embodiment, the paper container main body 1 and the top lid 6 are thermally welded using the plastic films 4 and 7 stretched over their respective inner surfaces, but it is also possible to bond them with an adhesive. That would be good. As explained above, when the top lid is loaded by the method of the present invention, the outer circumferential surface of the flange of the top lid 6 is extremely strongly crimped and bonded to the inner surface of the upper end of the paper container body 1 from the inside over its entire circumference. As a result, it has become possible to obtain a paper container that can reliably maintain airtightness and accommodate liquid contents 12 without leakage.
とくに、この発明では円盤８の各分割部分８ａに吸気孔

フランジ６ａを紙容器本体１の上端部内面に圧着するこ
とができて作業能率を著しく向上でき、また装置も極め
て簡略化できる。Particularly, in this invention, an intake hole 10 is provided in each divided portion 8a of the disk 8, so that the divided disk 8 alone can perform the adsorption action of the upper cover 6 and the action of crimping the flange 6a of the upper cover 6. Therefore, the top lid 6 can be sucked and inserted into the paper container body 1, and the flange 6a of the top lid 6 can be subsequently crimped to the inner surface of the upper end of the paper container body 1 while remaining in this inserted state, thereby improving work efficiency. This can be significantly improved, and the device can also be extremely simplified.
しかもフランジ６ａの紙容器本体１の内面に対する圧着
に際しては相隣る分割部分８ａ，８ａ間の間隙に相当す
る箇所をも圧着するので、フランジ６ａの全周にわたつ
て均一かつ完全にシールすることができて気密性に優れ
る利点がある。Moreover, when the flange 6a is crimped against the inner surface of the paper container body 1, the area corresponding to the gap between the adjacent divided portions 8a, 8a is also crimped, so that a uniform and complete seal can be achieved over the entire circumference of the flange 6a. It has the advantage of being airtight.
