DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on illustrated embodiments.

FIG. 1 is an exploded perspective view of a closed lid container according to the present invention, and FIG. 2 is a half sectional view of an assembled state thereof. As shown in the drawing, the closed lid container of the present invention has a lid 7 rotatably attached to a box-shaped main body 1 having an opening 3 formed in a top plate 2 so that the opening 3 can be opened and closed. The removable bottom cover 11 is detached, and a wet material such as a wet tissue is stored in the main body 1 from the back side of the main body 1.

The main body 1 has a substantially box shape with an open lower end, and has an opening 3 at the center of a top plate 2 which is one step lower than the periphery.
And an engagement receiving portion 4 is provided to protrude upward around the opening 3 and is formed of a synthetic resin having flexibility.

The cover 7 has a size substantially equal to the size of the top plate 2 of the main body 1 and is provided with an engagement projection 8 for engaging the engagement receiving portion 4 at a predetermined position on the back surface. It is a flat plate and is formed of a synthetic resin having flexibility.

The lid 7 is rotatably attached to the rear portion (the right rear side in FIG. 1) of the main body 1 by an appropriate means such as fitting of unevenness. In FIG. 4, reference numeral 10 denotes a pivot point serving as a pivot point of the lid 7.

Here, in the closed lid container of the present invention,
A recess 5 is formed in the upper part of the front surface of the main body 1 (the left front side in FIG. 1), and an operation lever 6 continuous with the top plate 2 is provided integrally with the top plate 2 so as to protrude into the recess 5. . The operation lever 6 has a central portion on the rear side of the top plate 2.
And a thin hinge portion 6a continuous with the hinge portion 6a.
The push-up pieces 6b, 6b are protruding rearward on both sides thereof so as to sandwich “a”.

The bottom cover 11 is substantially the same size as the lower surface of the main body 1 and has an engaging portion 1
2 are provided, and are formed of an elastic synthetic resin. Further, an elastic projection 13 which is capable of expanding and contracting in a bellows-like manner and serving as a pushing-up urging means for contents (not shown) is provided in the center portion by integral molding.

The closed lid container of the present invention has the above-described configuration.

In FIG. 1, reference numeral 9 denotes a push-up rib provided at a predetermined position on the back surface of the lid 7 by being integrally formed with the lid 7.

Next, the operation of the closed lid container of the present invention having the above-described structure will be described.

First, in the normal closed state, the opening 3 of the main body 1 is fitted to the cover 7 around its surrounding engagement receiving portion 4 as shown in FIG.
Are engaged and hermetically sealed. Therefore, the stored items (not shown) such as wet tissues are prevented from evaporating water, and are stored and stored in a wet state.

When taking out the contents, the main body 1
The operating lever 6 provided in the recess 5 may be pushed downward, so that the operating lever 6 connected to the top plate 2 via the thin hinge portion 6a can be moved forward with the hinge portion 6a as a fulcrum. (Left side in FIG. 4) is tilted downward, and conversely, the rear lifting piece 6b moves upward. At this time, since the push-up rib 9 of the lid 7 is located above the push-up piece 6b, the lid 7 is pushed up by the push-up rib 9 portion,
The pivot point 10 is rotated about an axis. Therefore, since the engagement between the locking receiving portion 4 and the locking projection 8 is released, the lid 7 can be easily rotated and opened thereafter, and has appeared below the lid 7. The contents can be taken out from the opening 3.

After the contents have been taken out in this manner, the lid 7 is rotated in the closing direction, and the main body 1 is removed from above.
The engagement protrusion 8 engages with the engagement receiving portion 4 and the opening 3 is sealed. At this time, the operation lever 6 is surely returned to its original state by its own elastic restoring force and the pushing-up piece 6b being pushed down by the pushing-up rib 9 of the lid 7.

It should be noted that the replenishment or replacement of the contents is carried out in the main body 1.
The bottom cover 11 engaged with the bottom is removed. The contents stored in the main body 1 are pushed up to the opening 3 side by an elastic projection 13 provided on the bottom cover 11 so that the upper part thereof can be easily taken out.

As described above, in the closed lid container of the present invention, the operating lever 6 and the lid 7 do not need to be provided with any engaging portions or hooks, and the operating lever 6 is integrally formed on the main body 1 side. Despite the configuration, the opening of the opening 3 can be reliably released.

In the illustrated embodiment, the lid 7 is provided with the push-up rib 9 provided on the back surface. However, the closed lid container of the present invention is provided with an operation lever integrally formed on the main body 1 side. It is sufficient that the cover 7 is pushed up by the swinging operation of 6. For example, if the rear end of the push-up piece 6b protrudes upward, the push-up rib 9 is not necessarily required.

Further, the bottom lid 1 is exemplified by one in which a bellows-shaped push-up portion 13 is integrally formed. However, the push-up portion 13 has a function of pushing up the contents or holding the contents at the pushed up position. The shape is not limited to the illustrated one, but may be formed by another member.

Further, in the embodiment, the bottom lid 11 is attached to and detached from the main body 1 so that the contents can be replaced or refilled. In the case of a single-use product such as a creamy product, the bottom of the main body 1 may be closed so as not to be opened and closed.

[0031]

As described above, according to the first aspect of the present invention, the engagement between the engagement receiving portion for closing the opening and the engagement projection and the engagement between the lid and the main body are performed. Since the main body is provided with an operation lever for releasing the engagement between the engagement receiving portion and the engagement projection, the operation lever is provided on the top plate in a swingable manner. There is no need to separately provide an engaging means such as a hook or an engaging portion on the lid side or the operation lever,
Further, the operation lever is formed at the same time by molding the main body. Therefore, there is an effect that the structure is simple, the structure of the manufacturing mold is simplified, and the manufacturing can be performed at low cost and with high efficiency.

According to the second aspect of the present invention, since the push-up rib for contacting the push-up piece of the operation lever is provided on the back surface of the cover, the strength of the cover increases, and the cover when pushed up by the push-up piece is provided. This has the effect of reducing the deflection and smoothing the operation and improving the durability.

According to the third aspect of the present invention, since the bottom of the main body is a detachable bottom cover and the bottom cover is provided with a pushing-up urging means for the contents, the contents can be easily replaced or replenished. In addition, the contents are always held at a position where they can be easily taken out, and there is an effect that the handleability is improved.
