In addition, not only the aesthetic appearance was impaired, but also the outer surface shape could not be freely configured (it could not be formed into a flat shape), and it was not possible to sufficiently meet demand. Also, at the time of stocking after the lid is formed, its outer surface 10
There was also a problem that the loading convenience was poor due to the uneven shape of 2.

構成されていることである。According to the present invention, there is provided a technical means for achieving the above object, in which a spoon locking structure is constituted by at least a pair of locking portions provided on a back surface of a lid body. The pair of locking portions includes elastic locking pieces that lock the outer peripheral edges of both the front end side and the rear end side of the spoon, and the elastic locking pieces are hanging rods that are vertically installed from the inner surface of the top surface of the lid body. And a claw portion extending inward from the lower end of the rod portion to form a substantially L-shape so that the respective insertion spaces are opposed to each other and one or both of the front end side and the front end and the rear end for engaging the spoon. Both sides have elasticity and are constituted by a plurality of locking pieces provided with slits between adjacent sides.

Therefore, the elasticity of each locking piece is very strong. The spoon can be easily opened and removed, and the spoon can be easily attached and detached. In addition, the elasticity of each locking piece that acts separately locks the tip of the spoon to the outer peripheral edge, so that any external load is applied. Even when the lid body is deformed, the respective locking pieces stably hold the spoon on the inner surface of the lid body according to the deformation of the lid body.

が図れる。According to the present invention, a spoon locking structure is constituted by at least a pair of locking portions provided on the back surface of the lid body, and the pair of locking portions is provided on both the front end side and the rear end side of the spoon. An elastic locking piece that locks the outer peripheral edge, the elastic locking piece includes a vertically extending rod portion that extends vertically from the inner surface of the top surface of the lid body and a claw portion that extends inward from the lower end of the rod portion. A plurality of slits are formed in a substantially L-shape so that the respective insertion spaces are opposed to each other and one or both of the front end side and the rear end side of the front end side for retaining the spoon are elastic and have slits between adjacent ones. Because of the locking pieces, the elasticity of each locking piece is not so strong and can be easily spread out to easily attach / detach the spoon. Is locked to the outer peripheral edge of both the front and rear ends of the Even if load is deformed the lid body consuming, engaging pieces each can be allowed to stably held the spoon lid body inner surface according to the deformation. Accordingly, it is possible to provide a container lid having a spoon locking structure that can be more stably locked and held while the spoon can be easily attached to and detached from the lid body.

The outer appearance of the entire container lid can be improved without making the outer surface uneven as in the case of the container lid, and the outer surface shape can be freely configured without limitation (it can be formed into a flat shape). It is possible to sufficiently cope with the problem, and it is possible to improve the loading convenience at the time of stocking after the lid is formed.
