Japanese Laid-Open Patent Publication Nos. 57-77440 and 5
As can be seen in 7-77441, etc., open a container by making multiple perforated cut lines in the continuous part of the container body and lid and tearing between the perforated cut lines. The present invention has been developed and proposed, in which a filamentous material is interposed in the continuous portion and the filament is pulled to cut the intervening portion of the filamentous material to open the container. After that, the present inventor commercialized and announced these applied products, and each company has filed an application based on these technical ideas as a basic idea and has published the application.

う技術思想に基づくものである。"Problems to be solved by the invention" However, in the above-mentioned both applications filed by the present inventor as well as the applications of each company filed thereafter, all the processing for opening is performed on the container, and the means for sealing the container is old. As described above, it is formed so as to seal the joint edge by means such as stapling or welding with a welding machine, and is based on the technical idea of cutting the joint edge of the container different from the sealing part when opening. It is a thing.
一方、容器の封緘を前述のホッチキスや溶着の代わりに

る。On the other hand, it is also known that the container is sealed with an adhesive tape instead of the above-mentioned stapler or welding. (Actual development 58-12
However, the known sealing structure using an adhesive tape is a structure in which the joint edge of the container is partially sealed with the adhesive tape, or a structure in which both ends of the joint edge of the container are left with a little adhesive tape. Therefore, it is difficult to present a method of automatically sealing by a mechanical device.

ことにある。The object of the present invention does not require any technical processing means for subjecting the container to the processing for opening, and at the time of opening, as in the case of the container subjected to the processing for opening, it is extremely easy. Another object of the present invention is to provide a container sealing method capable of unsealing a container, and further capable of automatically performing a sealing operation using an adhesive tape by using a mechanical device.

Pull out the wrapping tape material (6) coated with the number 6 1 to 6 6
The posture is sequentially changed to a U-shaped cross section as shown in FIG. The joint edges (4) and (5) of the container (A) in which the joint edge (5) of the lid (2) is brought into contact with the joint edge (4) of the main body (1) are The tape material (6) is moved into the U-shaped posture portion. Then, the joining edges (4), (5)
And the U-shaped posture by passing the tape material (6) in the U-shaped posture between the rolls (11), (11) arranged so as to face each other, from both outsides of the joining edges (4), (5). The tape material (6) is pressure-welded, and the tape material (6) is adhered to the bonding edges (4) and (5) over the entire length in the longitudinal direction on the bonding edges (4) and (5) of the container (A). . Roll (11), (1
In 1), in this embodiment, the U-shaped tape material (6) is pressed against the joining edges (4) and (5) and at the same time, the container (A) is rotated at the same speed. . Subsequently, the cutter (9) is composed only of the tape material that extends and extends outward in the longitudinal direction of the joining edges (4) and (5) in a double-folded posture between the preceding container and the succeeding container. The automatic sealing is completed by cutting the required cutting part (10). Since the cut portion (10) is located slightly away from the ends of the joining edges (4) and (5), the portion extending outward from the joining edges (4) and (5) can be finger-tipped. You have to pick it up and open it.
本発明にいう容器（Ａ）は、第５図に部分図で示したよ
うに鶏卵用の包装容器であってもよく、その他の内容物
を包装するための容器であってもよい。The container (A) referred to in the present invention may be a packaging container for eggs as shown in the partial view of FIG. 5 or a container for packaging other contents.

業性能が向上する。Also, the container itself can be an ordinary container that has not been subjected to any processing for opening, and since there is no need to perform processing for opening the container itself, use an inexpensive container itself. Moreover, the sealing work does not require the conventional sealing work by stapling or welding, and instead of these sealing means, tape materials are used for continuous sandwiching and adhesion. , The sealing work can be automated, and the work performance is improved as compared with the conventional sealing means.

できる。Further, in the sealing method of the present invention, the container can be opened by a one-touch means by simply grasping and peeling off the extension protruding portion of the tape material constituting the sealing portion itself to the outside of the container, so that the container can be opened. The container can be opened very easily like the specially processed one. Moreover, since the sealed part itself is opened, it does not completely destroy the container like the above-mentioned known special processing for opening, so the container after opening is collected and reused. It is possible to expect an effect that can be achieved, which is completely impossible with conventional and conventionally known ones.
