BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. The container 1 of the present invention includes a container body 2 and a cap 3, and the cap 3 further includes a cap body 4, a cover plate urging member 5, and a cover plate member 6. The cap body 4 has a top wall 8 that closes the upper end opening of the container body 2 extending from an upper end edge of a peripheral wall 7 that is airtightly fitted to the outer periphery of the upper end opening portion of the container body 2. A main recess 9 is provided, and a rear end of the main recess 9 is provided with a first auxiliary recess 10 for attaching a cover plate. Further, in front of the main recess, a second auxiliary recess 11 for pushing a pressing plate is provided. Is recessed. Further, a cylindrical portion 12 is erected at the center of the main concave portion 9, and an outlet 13 is formed in the top wall inside the cylindrical portion 12.

In this embodiment, a first auxiliary recess 10 having a rectangular shape in plan view is connected to the central portion of the rear end of the main recess 9 having a circular shape in plan view. Further, the second auxiliary recess 11 has a horizontally long rectangular shape in plan view which is recessed at the front spaced position of the main recess 9.
The top wall between 11 and the main recess 9 is slightly recessed to form a recess 14 into which the base end of a pressing plate described later is fitted and mounted. The cylindrical portion 12 has a cylindrical shape, and an engaging projection 15 is provided on the upper portion of the front surface of the cylindrical portion 12. The take-out port 13 is formed in a cross-shaped cut groove for taking out the wet tissue.

The cover plate urging member 5 is made of a flexible and highly elastic material, for example, silicon rubber. Further, a projecting piece 18 which extends vertically from a front edge of a fixed plate portion 17 fixed to an upper step 16 of a step portion which is formed on the bottom surface of the first auxiliary recess 10 and which descends to the front side is provided in a protruding manner. In the present embodiment, a projecting piece 18 that is inclined upward and forward from the front edge of the rectangular plate-shaped fixed plate portion 17 and that is inclined downward and downward is projected.
Then, the tip of the fixing plate portion 17 is slightly projected forward from the upper step portion 16 to be fixed, and the lower end edge of the protruding piece 18 is brought into contact with the lower step portion 19 to be fixed to the cap body 4. Fixed plate part 17
An appropriate fixing means such as an adhesive can be used for fixing the above-mentioned No. 2, but it is preferable to sandwich and fix it by a cover plate member 6 which will be described later from the viewpoint of convenience in manufacturing and good durability.

The lid plate member 6 connects the rear edge of the lid plate 22 openably and closably via the hinge 21 to the front edge of the substrate 20 fixed on the fixed plate portion 17, and the rear surface of the base end portion of the lid plate 22 is the above-mentioned. The lid 18 is maintained in an open state by abutting and locking the rear surface of the protrusion 18. In the present embodiment, the upper end opening of the main recess 9 and the upper end opening of the first auxiliary recess 10 are inserted through the hinge 21 formed thinly on the front edge of the rectangular plate-shaped substrate 20 fitted in the rear part of the first auxiliary recess 10. A cover plate 22 that substantially covers the front end portion is extended, and as shown in FIG. 4, the projecting piece 18 keeps the cover plate 22 upright. Further, the lower end of the rod-shaped portion 23 protruding from the lower surface of the substrate 20 is fitted into the fitting hole 25 formed in the upper step 16 of the step portion through the through hole 24 penetrating the fixing plate portion 17, and fitted. The fixing plate portion 17 and the substrate 20 are fixed to the cap body 4 by being fixed in the hole 25 by a fixing means such as fusion or adhesion.

Further, a fitting cylinder 26 is projected from the rear surface of the cover plate 22,
When the cover plate 22 is closed against the resilience of the projecting piece 18, the fitting cylinder 26 is engaged with the cylinder portion 12 of the cap body 4 and locked. . In this embodiment, the lid plate 22
A locking projection (27) that engages with the above-mentioned engagement projection (15) is provided on the inner surface of the front part of the cylindrical fitting tube (26) protruding from the center of the back surface.

Further, the second auxiliary recess 11 is formed from the front edge of the cover plate 22.
By pushing down the pressing plate portion 28 protruding from the inner upper portion, the engagement between the cylinder portion 12 and the fitting cylinder 26 is released and the lid is opened. In this embodiment, the rear end edge of the pressing plate portion 28 is connected to the tip end portion of the lid plate 22 via the hinge 29, and the recess 14 is formed.
A base end portion is fitted and mounted inside, and a pressing plate portion 28 is exposed to the upper end opening portion of the second auxiliary recess 11 so as to be able to be pushed down.

Then, from the state shown in FIG.
5 is pushed down, the base end portion of the pressing plate portion 28 and the front portion of the cover plate 22 are pushed upward with the front end edge portion of the lower surface of the recess 14 as a fulcrum.
As shown in (b), the engagement projection 15 and the engagement projection 27 are disengaged, and then the lid 18 is opened by the elastic restoring force of the projecting piece 18 to maintain the opened state.

A hinge 29 is provided at the boundary between the cover plate 22 and the pressing plate portion 28.
Although the hinge is provided, the engagement can be released without necessarily providing this hinge. Further, each member described above is preferably formed of synthetic resin unless otherwise specified.

[0015]

As described above, according to the container of the present invention having the above-mentioned structure, the lid body is unlocked by a simple operation of pushing down the pressing plate portion, and the lid plate is securely attached. The lid is automatically opened by the action of the biasing member, and the lid can be easily opened even if the fitting tube of the lid plate is fitted relatively tightly in order to obtain the hermeticity.

Further, since the lid plate urging member has a relatively large and simple structure, the assembly operation can be easily performed as compared with an elastic member such as a torsion spring which is conventionally used for urging the lid plate to open the lid. There is.

Further, since the lid plate urging member is provided with a projecting piece which extends vertically from the fixed edge of the fixed plate portion, the lower end edge of the projecting piece can be brought into contact with the upper surface of the top wall. When the closed lid plate is opened, not only the elastic restoring force above the protruding piece but also the elastic restoring force below the protruding piece acts, so that the lid can be opened more reliably.

Further, since the lid plate urging member and the lid plate member can be housed in the respective recesses, the upper surface of the cap can be made substantially flat, and the stacking can be performed stably. In addition to the above effects, the invention according to claim 2 also exhibits the effect that the lid plate urging member and the lid plate member can be reliably fixed to the cap body, and there is very little risk of detachment.
