Description of the Related Art A thin cup-shaped container, which is a synthetic resin injection-molded product often used as a container for storing cheese, butter, and yogurt, is filled with contents and immediately has an opening such as a seal sheet. Sealed by welding, then in the opening of the container body sealed with a seal sheet, etc.
A flat dish-shaped lid that covers this opening and protects the seal sheet is fitted to the outside.

きるようにしている。[0003] As described above, the lid in this kind of container with a synthetic resin lid merely protects the mechanically weak seal sheet mechanically. However, recently, the lid has been turned down. It is formed in a deep dish shape, a storage space is formed between the lid and the seal sheet, and a tool such as a spoon or a seasoning such as a sauce is integrally attached to the storage space, thereby allowing the contents to be contained. They can easily eat and drink according to their tastes.

ること、にある。Means for Solving the Problems Among the present invention for solving the above technical problems, the means according to the first aspect of the present invention comprises a container body which is a wide-open cup-shaped thin-walled container, and an opening of the container body. And an open cylindrical portion forming an opening of the container body, and a locking piece is protruded from the outer peripheral surface to stand upright. At the lower end of the outer peripheral surface of the fitting cylinder piece, a ring piece is provided around the outer flange, and the fitting piece is configured.
The engaging projection formed on the inner peripheral surface of the assembled portion formed on the peripheral end of the lid body, which is engaged with the engaging piece of the container body from below and is engaged with the engaging piece of the container body. A plurality of fitting ribs, in which a fitting cylinder piece of a container body that is tilted and bent and deformed inward by fitting with the fitting cylinder piece, abuts on the inner side of the fitting cylinder piece detachably fitted to the outside in the circumferential direction. At least, the inner diameter of the projecting end of the locking projection of the lid is set to a value slightly smaller than the outer diameter of the fitting cylindrical piece of the container body. is there.

リング片に突き当たるまで押し下げると、蓋体は、その
係止突片を容器本体の係止片に下方から係止させた状態
で、容器本体の開口部に外嵌組付きする。When the lid is placed over the opening cylindrical portion of the container body from above and is fitted to the outside as it is, and is pushed down until the fitting cylinder piece of the lid comes into contact with the ring piece of the container body, the lid is brought into contact with the locking projection. In a state where the piece is locked from below by the locking piece of the container body, an outer fitting assembly is attached to the opening of the container body.

化し、不安定化することになる。When the lid is externally fitted to the opening of the container body, the locking piece of the container body and the locking projection of the lid are undercut-coupled, so that the lid is fitted to the container body. Although the assembling is maintained, the fitting cylindrical piece of the container body is partially tilted inward because the inner diameter of the protruding end of the locking projection of the lid is slightly smaller than its outer diameter. As a result, the undercut connection of the lid to the container body is weakened and destabilized.

の外嵌組付きが、強固に安定して維持される。However, the fitting tube piece portion of the container body facing the fitting rib of the lid abuts on the fitting rib and is only slightly bent and deformed inward. The locking between the piece and the locking projection of the lid is stably and firmly secured, whereby the external fitting of the lid to the container body is firmly and stably maintained.

る。When the lid is removed from the container body, that is, when the container body is opened, a pulling force is applied to a part of the fitting cylinder piece of the lid, whereby the fitting cylinder piece part is tilted and bent outward. By deforming and releasing the locking of the locking piece to the locking piece and subsequently applying a lifting force, the unlocking of the locking piece and the locking piece is released over the entire circumference and achieved.

体に対する蓋体の装着が良好に達成できる。According to the second aspect of the present invention, when the assembled portion of the lid is externally fitted to the opening cylindrical portion of the container body, the fitting cylinder of the container body is tilted and deformed inward. The piece abuts against the fitting rib to prevent the external fitting of the lid from the container body from being impossible or difficult to achieve,
Also, the maximum tilting and bending deformation of the fitting cylinder piece of the container body, which occurs when the locking projection of the lid rides over the locking piece of the container body, can be smoothly and smoothly performed, thereby enabling the container body to be smoothly moved. The attachment of the lid can be achieved satisfactorily.

The container body can be used as a welded mounting surface of a seal sheet for hermetically sealing the container body. When the container bodies are stacked (fitted and stacked), the upper end of the fitting cylinder piece of the lower container body is placed in the upper container. Since the lower end of the main body abuts against the outer peripheral edge of the lower surface of the main body from below, a stable stacked state of the container main bodies can be obtained.

して構成されている。The assembling portion 11 is provided at a lower portion of the inner peripheral surface of a fitting cylindrical piece 12 which is vertically provided from the peripheral edge of the lid main body 10 and has a short cylindrical shape having a diameter dimension to be fitted to the fitting cylindrical piece 4. In addition, a locking projection 13 whose projection end inner diameter is slightly smaller than the outer diameter of the fitting cylinder piece 4 is protrudingly provided, and is mounted on the ring piece 6 at the lower end edge of the fitting cylinder piece 12. A mounting ring plate 14 having a knob 19 extending therefrom is continuously provided in an outer flange shape.
A step 15 for the stack, which has a width larger than the wall thickness of the stack 2 and faces upward, is formed.
A plurality of (up to five in the illustrated embodiment) fitting ribs 16 in the form of an upright plate are vertically provided at intervals along the circumferential direction with a certain gap provided between the fitting ribs 16 and the fitting ribs 16. The mating rib 16 is configured to be reinforced by a short cylindrical inner cylinder piece 18 vertically suspended inside the fitting cylinder piece 12.

When the locking projection 13 gets over the locking piece 5,
Even if the fitting tube piece 4 is greatly tilted and deformed in the diameter reducing direction, the upper end of the fitting tube piece 4 is fitted with the fitting tube piece 12 and the fitting rib 16.
To smoothly and surely enter the gap between them.

Although the cylindrical piece 4 is tilted and deformed in the diameter reducing direction, the fitting rib 1
Only the portion of the fitting tube piece 4 facing the fitting rib 6
The degree of the bending deformation is regulated by the contact with the locking pieces 5 and the locking pieces 5 and the locking protrusions 13 according to the degree of the restriction.
And the lid 9 is firmly and stably attached to the container body 1 accordingly.

全なものとすることができる。Since the present invention has the above-described structure, the following effects can be obtained. According to the first aspect of the present invention, the engagement ribs arranged at intervals along the circumferential direction enhance the locking force between the container body and the lid at the portion facing the engagement rib. Therefore, the attachment of the lid to the container body can be made strong and stable,
Therefore, handling before opening can be made safe without causing unauthorized opening.
