It may be a thing.
In the following, the horizontal direction shown along the long side of the container with a lid having a substantially rectangular shape in a plan view will be described as the longitudinal direction, and the vertical direction shown along the short side will be described as the short direction.

First, the first embodiment of the present invention will be described with reference to FIGS. 1 to 3.
The container with a lid shown as the first embodiment of the present invention is mounted in a state of being fitted to the container body 10 for accommodating the contents and the open end 10A of the container body 10, and the container body 10 is set to the closed state. It is configured to have a possible lid 20.

The container body 10 is continuously provided above the bottom wall 11 having a substantially rectangular shape in a plan view formed by rounding the corners, and the four sides (two short sides and two long sides) of the bottom wall 11. It is formed by having a container-side peripheral wall 12 forming an opening end 10A at the upper end thereof and a flange portion 13 provided around the opening end 10A. The tip of the flange portion 13 is a locked portion 14 projecting outward in the radial direction. The radial outer side in the specification means a direction toward the flange portion 13 side with respect to the inner center of the container body 10.

The lid 20 has a top wall 21 having a substantially rectangular shape in a plan view formed by rounding the corners, and a lid hung from the four sides (short sides on the left and right and long sides on the front and back) of the top wall 21. It is configured to have a side peripheral wall 22, and a step portion 23 composed of a plurality of steps is provided at the lower end of the lid side peripheral wall 22. Locking portions 24 that can be engaged with the locked portion 14 of the flange portion 13 on the container body 10 side are formed at four positions on the inner peripheral surface of the stepped portion 23 constituting the lid-side peripheral wall 22. ing. As shown in FIGS. 2 and 3, the locking portion 24 is formed to have a substantially U-shaped cross section, and is a locked portion projecting from the tip of the flange portion 13 on the container body 10 side. It is possible to engage with 14.

Further, on the front side (front side) of the long side of the lid side peripheral wall 22, the deformed portion 30 is located at two positions (positions near the corners of the lid 20) having a space between the left and right sides of the central portion. Is formed in each case, and the deformed portions 30 are similarly formed on the lid side peripheral wall 22 on the rear side (rear side) facing each other in the lateral direction (four places in total).
As shown in FIG. 2, the deformed portion 30 shown in the first embodiment is composed of a bellows 31 in which a part of the lid side peripheral wall 22 and the step portion 23 is formed in a wavy shape, and the step portion 23 is formed on the lid side peripheral wall 22. They are arranged so as to cross in the height direction. Further, the deformed portion 30 is configured so that the wavelength of the bellows 31 on the lower side is longer than that of the bellows 31 on the upper side, and the entire deformed portion 30 is formed into a substantially isosceles triangle shape (or a substantially fan shape) in a plan view. As shown in FIG. 3, the deformable portion 30 is elastically deformable, and the base BC side of the substantially isosceles triangle which is the lower end side with the apex A of the upper end portion in the height direction of the substantially isosceles triangle as a fulcrum is It is configured so that it can be opened wide in a substantially fan shape along the longitudinal direction .

As shown in FIG. 2, when the lid 20 is attached to the open end 10A of the container body 10 and pushed downward, the locking portions 24 on the lid 20 side are locked on the container body 10 side at four positions. By overcoming the portions 14 and engaging with each other, it is possible to set the closed state in which the lid 20 and the container body 10 are fitted.

Next, in order to open the lid 20 in the open state, as shown in FIG. 3, the vicinity of the central portion of the top wall 21 of the lid 20 is, for example, the first finger (four fingers excluding the thumb or four fingers or the like). One of these fingers) While pressing with F1 in the same manner as below, the operation of lifting the lower end of the lid-side peripheral wall 22 on at least one short side with the second finger (thumb, the same applies hereinafter) F2 is performed. Then, the deformed portion 30 opens wide in a substantially fan shape in the longitudinal direction with the apex portion A on the upper side as a fulcrum, and the lid 20 elastically deforms upward. The engagement between the locking portion 24 on the lid 20 side and the locked portion 14 on the container body 10 side can be easily released. Therefore, the lid 20 can be lifted as it is to open the lid. As described above, the container with a lid of the present invention can be easily opened with only one hand operation.
When the finger is released from the lid 20 after opening the lid, the bellows 31 that has been opened in a fan shape is restored and deformed to return to the original closed state (see FIG. 2), so that the lid 20 is returned to the original closed state. The operation to return can be eliminated.

Next, a second embodiment of the present invention will be described with reference to FIGS. 4 and 5.
The container with a lid shown in the second embodiment is different from the first embodiment in the configuration of the deformed portion 30, and other configurations and effects are the same as those in the first embodiment. Therefore, in the following, the points different from those of the first embodiment will be mainly described.
The deformed portion 30 shown in the second embodiment is formed by forming a part of the lid-side peripheral wall 22 with a recess 32 that crosses the stepped portion 23 in the height direction. When the deformed portion 30 is formed by the recess 32 in this way, the deformed portion 30 can be configured so as not to protrude to the lid side peripheral wall 22 side. It is also possible to form the deformed portion 30 with a convex portion.

Also in the container with a lid shown in the second embodiment, similarly to the first embodiment, the vicinity of the central portion of the top wall 21 of the lid 20 is pushed by, for example, the first finger F1 from the closed state shown by the solid line in FIG. However, by lifting the lower end of the lid-side peripheral wall 22 on at least one of the short sides with the second finger F2, the lid 20 can be elastically deformed as shown by the broken line.
That is, when the lower end of the lid-side peripheral wall 22 is lifted by the second finger F2, the deformed portion 30 formed by the recess 32 extends in the longitudinal direction and is deformed so as to open substantially in a fan shape. Therefore, since the lid 20 is deformed upward, the engagement between the locking portion 24 on the lid 20 side and the locked portion 14 on the container body 10 side is released, and the lid can be easily opened by operating one hand. It becomes possible to make it into a state.
Further, as in the first embodiment, when the finger is released from the lid body 20 after the lid is opened, the recess 32 that has been opened in a substantially fan shape is restored and deformed to return to the original closed state, so that the lid body 20 is originally closed. The operation for returning to the state (see the solid line in FIG. 5) can be eliminated.

Next, a third embodiment of the present invention will be described with reference to FIGS. 6 and 7.
The container with a lid shown in the third embodiment is different from the first and second embodiments in the configuration of the deformed portion 30, and other configurations and effects are the same as those in the first or second embodiment. Therefore, in the following, the points different from the first or second embodiment will be mainly described.
The deformed portion 30 shown in the third embodiment is formed by forming a part of the lid-side peripheral wall 22 by a slit 33 in which the stepped portion 23 is cut out in the height direction.
Similarly to the first and second embodiments, the lid 20 can be deformed from the closed state shown by the solid line in FIG. 7 as shown by the broken line in the container with the lid shown in the third embodiment.
That is, when the lower end of the lid-side peripheral wall 22 is lifted by the second finger F2, the top wall 21 on the lid-side 20 side is deformed into a substantially "<" shape (see the broken line in FIG. 7), and the lid-side peripheral wall 22 is formed. The deformed portion 30 provided in the above is deformed so that the slit 33 opens in the longitudinal direction. In particular, the deformed portion 30 opens substantially in a fan shape in the longitudinal direction, and the lid 20 deforms upward. Therefore, similarly to the above, the engagement between the locking portion 24 on the lid 20 side and the locked portion 14 on the container body 10 side is released, and the lid can be easily opened by operating one hand.
Further, in the third embodiment, the lid 20 returns to the original closed state (see the solid line in FIG. 7) due to the restoring force of the top wall 21 which has been deformed into a substantially “dogleg” shape. Alternatively, the lid 20 may be returned to the original closed state (see the solid line in FIG. 7) by the weight of the deformed portion of the lid 20 or the operation of the operator.

Although the configuration of the present invention and its action and effect have been described above with reference to Examples, the embodiments of the present invention are not limited to the above Examples.
For example, in the first to third embodiments, the case where the locking portions and the locked portions arranged so as to face each other are provided at two positions on the short sides on both the left and right sides in the longitudinal direction has been described. The present invention is not limited to each of the above embodiments, and a configuration may be provided only on one of the short sides in the longitudinal direction, and a configuration may be provided at one or more locations.

In the first to third embodiments, the first finger F1 is defined as four fingers excluding the thumb or one of these fingers, and the second finger F2 is defined as the thumb. However, the thumb is the first finger. The finger F1 may be used, and the four fingers other than the thumb or any one of these fingers may be used as the second finger F2.

Further, in the third embodiment, the case where the slit 33 is formed linearly over the entire length of the deformed portion 30 has been described. However, for example, the substantially triangular shape may be a slit 33 that opens in a substantially fan shape. In this case, it is preferable that the apex of the slit 33 having a substantially triangular shape or a substantially fan shape is arranged below the locked portion 14 on the container body 10 side.

The container with a lid of the present invention can be used in a wider range of applications in the field of a container that improves operability when the lid body is removed from the container body.
