Plastic or paper containers with wide openings are often used to hold butter, margarine, yogurt, etc. In order to completely seal the inside of these containers at the time of sale, a thin sheet of material is glued and attached to the periphery of the opening, and an outer lid is also attached to reclose the container after the sheet is torn off. ing. Using an inner lid (sheet material) and an outer lid in this manner is not preferable because it complicates the manufacturing process and increases manufacturing costs. In order to solve these drawbacks, a container with a lid was proposed, which could be sealed with a single lid and reclosed with the lid after opening.
It is disclosed in Publication No. 78289. The device disclosed in this publication seals the container by adhering a lid that can be snapped onto the container opening to the flange on the outer periphery of the container opening. The lid, together with the flange, is removed from the container by tearing off the annular weakened area that has been formed, and is then reclosed by snap-fitting the lid into the container opening.

However, the container with a lid disclosed in the above publication has the advantage of being able to seal and reclose the container with a single lid, but uses an ultrasonic seal to bond the lid to the flange of the container. It was discovered that a problem occurred. That is, because a conventional lid snaps onto a container opening and has a body that fits tightly within the opening, ultrasonic vibrations are applied to the lid to ultrasonically seal the lid to the container flange. Then, the ultrasonic vibrations are also applied to the body, which is tightly fitted into the container opening, and this part also becomes strongly welded. Therefore, even if an attempt was made to open the lid by tearing off the weak part of the flange, the body of the lid was strongly adhered to the opening of the container and could not be opened.
本考案はかかる従来技術の欠点を解消せんとす

触する部分が生じないよう間隙を形成したことを
特徴とする。
In the container with a lid of the present invention, the opening of the container main body has an inward protrusion on at least a part of its inner periphery, and the lid has a recess in its body that receives the protrusion and a bulge below the recess. It is characterized in that it has a protrusion, and furthermore, a gap is formed so that there is no strong contact between the inner surface of the opening of the container body and the outer surface of the body of the lid.

As mentioned above, since a gap is formed between the inner surface of the opening of the container body and the outer surface of the body of the lid, when the body of the lid is inserted into a predetermined position within the opening of the container body, the body of the lid A gap is created between the outer surface and the inner surface of the opening, resulting in non-contact, and even if the insertion position of the lid is slightly shifted, only a small portion of the outer surface of the body and the inner surface of the opening will come into light contact.
In any case, there is no strong contact between the outer surface of the body and the inner surface of the opening. In this state, the flange of the container body and the flange of the lid are ultrasonically sealed, but even if the inner surface of the opening of the container body and the outer surface of the body of the lid undergo ultrasonic vibration, there will be strong contact between them. Since there are no parts, there is no adhesion and the lid can be opened easily.

After filling the container body 2 shown in FIG. 2 with contents, such as yogurt, the lid 3 is covered as shown in FIGS. 3 and 4, and the flange portion 16 is overlapped with the flange portion 8 of the container body 2. Next, a retainer is placed under the flange portion 8, and an ultrasonic horn is placed on the flange portion 16 to apply ultrasonic vibration to the flange portion 16 to seal it. Thus, the flange portions 8, 16
is securely sealed. At this time, the ultrasonic vibration applied to the flange portion 16 of the lid 3 is applied to the body portion 15 of the lid.
The ultrasonic vibrations are transmitted to the body 15 as well, but as shown in FIG. Therefore, there is no need to glue at this part. Note that when the lid 3 is placed over the container body 2, the position of the lid 3 may be slightly shifted and a part of the outer surface of the body may come into contact with the inner surface of the opening of the container body 2.
In this case, since the contact area is extremely small and is only touched lightly, no adhesion occurs. By adhering the flanges 8 and 16, a completely sealed container is sold as is.
