Description

  The present invention relates to a container with a lid mainly used as a disposable lunch container.

  Conventionally, disposable lunch containers, such as folding boxes, have been widely used, and there is known a means for protecting a stored food by heat-sealing a film or a lid member on the surface of the container after storing the food. (Patent Document 1).

  In a normal disposable lunch box, a thin resin container produced by integral molding with a lid is covered with a transparent lid or the like with its edge hanging down, and this lid is usually adhered so as not to be separated from the container. Fastened with tape.

  Further, as means for mounting the lid body in a sealed state on the container body, there is also provided a means for forming a recess closely fitted to the upper ridge of the container body on the lid body side, and mounting the lid body by fitting the upper ridge and the recess. It is known (Patent Document 2).

FIG. 1 of JP-A-2002-225964. FIG. 2 of JP-A-2001-206408.

  When the above-mentioned heat sealing means stores fresh food like a disposable lunch, performing heat sealing may affect the food, and the sealing operation itself is complicated.

  Also, since the means for fixing the lid with the adhesive tape cannot seal the stored items, there is a possibility that the contents may be spilled if the container is tilted. Also, the work of attaching the adhesive tape is troublesome.

  Further, the means for pressing the lid from above to fit and fit the upper ridge of the container body with the concave portion of the lid is easy to attach the lid, but is fitted over the entire surface. Therefore, even if the user tries to remove the lid and turns it up from one end of the lid, the lid does not come off easily, and the work of removing the lid is troublesome.

  Therefore, the present invention proposes a novel container with a lid in which the lid can be easily attached and detached and the lid can be securely attached.

  The container with a lid according to the present invention (claim 1) is made of a thin-walled resin that is produced by integral molding, and the adjacent side is linear and non-widened when viewed from a predetermined side, and a flange is provided around the container. The body is formed of a body and a lid, and one of the flanges on a side other than the predetermined one side is formed with a folded part in which the other flange is closely inserted, and formed continuously with the flange. Things.

  Therefore, after storing the desired food or the like in the container body, with respect to the flange having one of the folded portions, the flange of the other member is provided between the folded portion and the flange from a predetermined side having no folded portion. When inserted, the lid is attached to the container. In particular, when the food is formed by using a material that can be used in a microwave oven and the food is heated in the microwave oven, since the folded portion does not exist on the predetermined side, the vapor escapes from the predetermined side.

  The present invention (Claim 2) particularly has a stopper formed by forming a recess or a small hole in one of the flanges on a predetermined side and providing a protrusion in the other flange to fit into the recess or the small through hole. When the lid is attached to the container body, they are fitted and fixed to each other when the lid is attached to the container body, and the detachment (sliding movement) of the lid is prevented.

  In the present invention (claims 3 and 4), the partition is formed integrally with the container, and the lid is provided with a sealing portion into which the partition is fitted corresponding to the partition of the container. Further, the flange portion on the predetermined side is formed wider and a through hole is formed, and the flange portion is used as a handle, and the other flange portion is inserted between the folded portion and the flange portion from the predetermined side. Then, the upper part of the partition part is fitted to the sealing part, and the space between the partition spaces is reliably shut off. Further, by forming a handle on a predetermined side, carrying becomes possible.

  Further, since the present invention (claim 5) is made of a biodegradable resin, it can be discarded as it is.

  Since the present invention (claim 1) is as described above, it is possible to easily attach the lid by simply inserting the lid from the predetermined side, and to easily detach the lid, and to remove the lid from the other side. Since the side portion has one flange portion closely inserted between the other flange portion and the folded portion, a sufficient airtightness can be ensured.

  In particular, by providing the fastening structure after the lid is attached (claim 2), the lid is more securely attached, and the practicability is improved.

  Further, by forming the partition portion, forming a sealing portion to be fitted with the partition portion (Claim 3), and forming a handle (Claim 4), the sealing performance of the partition space is enhanced, and its portable function is enhanced. It is a thing.
