Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a perspective view of the storage container 1. As shown in FIG. 2 and 3 are perspective views showing the lid section 20 in an open state. FIG. 2 shows the lid section 20 from the front, and FIG. 3 shows the lid section 20 from the rear. FIG. 4 is a longitudinal sectional view showing the lid section 20 in a closed state.

The storage container 1 includes a main body part 10 and a lid part 20. The main body portion 10 is formed into a cylindrical shape with a bottom. The main body part 10 stores contents such as a roll of wet tissue (not shown) inside, and has an open top. A roll of wet tissue is formed by impregnating water, a humectant, etc. with water-resistant paper or nonwoven fabric. Also. The wet tissue roll has break lines (not shown) formed at predetermined intervals in the longitudinal direction.

A male threaded portion (not shown) is formed along the circumferential direction on the outer circumferential surface of the upper end portion of the main body portion 10 . The main body portion 10 is molded by injection molding or the like using a thermoplastic resin such as polypropylene, polyethylene, or polyvinyl chloride.

The lid part 20 is formed in a cylindrical shape with an open lower end, and has an upper surface part 21 and a peripheral surface part 22. The upper surface portion 21 is formed into a disk shape and covers the upper surface of the main body portion 10 . The upper surface portion 21 has a first recess 21a and a second recess 21b formed therein. The first recess 21a is formed in the center of the upper surface portion 21 so that the upper surface thereof is depressed downward. The second recess 21b is formed into a substantially rectangular shape when viewed from above, with its upper surface further recessed downward in the center of the first recess 21a.

The peripheral surface portion 22 extends downward from the outer peripheral edge of the upper surface portion 21 . A female screw portion 22a is formed along the circumferential direction on the inner peripheral surface of the peripheral surface portion 22 (see FIG. 4). The female threaded portion 22a is screwed into a male threaded portion (not shown) of the main body portion 10. Thereby, the lid part 20 is removably attached to the main body part 10, and the roll of wet tissue can be easily refilled.

The upper surface portion 21 and the peripheral surface portion 22 are integrally molded by injection molding or the like using a thermoplastic resin such as polypropylene, polyethylene, or polyvinyl chloride.

The lid portion 20 includes an opening portion 30, an opening/closing lid 31, an elastic member 32, a locking portion 33, and a relief portion 34. The opening portion 30, the locking portion 33, and the relief portion 34 are formed integrally with the upper surface portion 21. The opening/closing lid 31 and the elastic member 32 are separate members from the upper surface portion 21, respectively, as will be described later, and the lid portion 20 is constructed by assembling these members.

The opening 30 opens on the upper surface of the second recess 21b. The relief portion 34 is arranged closer to the hinge portion 31a of the opening/closing lid 31 than the opening 30, and is formed by recessing the upper surface of the second recess 21b downward.

The elastic member 32 is made of a plate-shaped elastic body such as silicone rubber, and has a substantially rectangular shape when viewed from above. The elastic member 32 is fixed to the upper surface of the second recess 21b and covers the upper surface of the opening 30 and the escape section 34. The height of the upper surface of the elastic member 32 is approximately the same as the height of the upper surface of the first recess 21a, and the lower surface of the opening/closing lid 31 comes into contact with the elastic member 32 and the first recess 21a when the lid is closed. In addition to silicone rubber, the elastic member 32 may be made of butadiene rubber, ethylene propylene rubber, styrene rubber, polyethylene terephthalate rubber, urethane rubber, or the like.

The elastic member 32 has an outlet 32a opening opposite to the opening 30. The outlet 32a has a smaller diameter than the opening 30. Thereby, drying of the wet tissue can be reduced. Further, the periphery of the outlet 32a formed by the elastic member 32 is easily deformed. Therefore, the wet tissue can be easily pulled out without damaging it. Moreover, the elastic member 32 has a plurality of protruding pieces 32e that protrude from the periphery of the outlet 32a toward the center of the outlet 32a. The protruding piece 32e has flexibility and holds the upper end of the cut wet tissue protruding from the outlet 32a. Note that a plurality of slits extending radially from the periphery of the outlet 32a may be formed instead of the protruding piece 32e.

The opening/closing lid 31 is formed into a plate shape and fits into the first recess 21a when the lid is closed. The opening/closing lid 31 includes a hinge portion 31a, a protruding portion 31b, a locking claw 31c, a rib 31d, a lid protrusion 31e, and a connecting portion 31f.

One end of the opening/closing lid 31 is connected to a connecting portion 31f via a hinge portion 31a. The connecting portion 31f is fixed to the upper surface portion 21 by the lid protrusion 31e as described later. Thereby, the opening/closing lid 31 becomes rotatable with respect to the upper surface portion 21 via the hinge portion 31a. By rotating the opening/closing lid 31, the opening 30 and the outlet 32a are opened and closed.

The rib 31d protrudes from the lower surface of the opening/closing lid 31 and is formed in an annular shape. The rib 31d surrounds the opening 30 when the lid is closed. At this time, the lower end of the rib 31d presses the elastic member 32. This improves the airtightness around the opening 30 and prevents the wet tissue housed in the main body 10 from drying out.

The protruding portion 31b protrudes from the lower surface of the opening/closing lid 31. The protruding portion 31b faces the elastic member 32 when the lid is closed, and enters the relief portion 34 while pressing the elastic member 32 (see FIG. 4). The relief portion 34 allows deformation of the elastic member 32 to escape when the protrusion portion 31b abuts the elastic member 32. When the protruding portion 31b enters the relief portion 34, the elastic member 32 is greatly deformed, and a stronger elastic force acts on the protruding portion 31.

The relief portion 34 is formed by recessing the upper surface of the upper surface portion 21 downward, and can prevent the airtightness around the relief portion 34 from deteriorating. Note that the relief portion 34 may be formed to penetrate the upper surface portion 21.

Further, by arranging the relief portion 34 closer to the hinge portion 31a than the opening portion 30, the opening/closing lid 31 can be closed with a small force while pressing the elastic member 32 with the protruding portion 31b using a lever action. This improves convenience when closing the lid.

The locking pawl 31c projects outward from the peripheral edge facing the hinge portion 31a and is releasably locked to the locking portion 33.

The locking portion 33 is disposed on the outer peripheral side of the first recess 21a, and includes an upright portion 33a, an actuating portion 33b, and a locking hole 33c. The locking claw 31c of the opening/closing lid 31 is inserted into the locking hole 33c. The lower part of the locking hole 33c is disposed in a part of the inner circumferential wall 21c of the first recess 21a, and is formed by penetrating the inner circumferential wall 21c toward the outer circumferential side. The upper part of the locking hole 33c is formed by the upright portion 33a. The upright portion 33a extends upward from the upper surface of the upper surface portion 21 and is formed so as to straddle the locking hole 33c in the circumferential direction. The actuating portion 33b projects radially outward from the outer circumferential surface of the upright portion 33a.

When closing the opening/closing lid 31, the locking pawl 31c slides downward while coming into contact with the inner peripheral surface of the upright portion 33a and bending the upright portion 33a toward the outer peripheral side. When the locking claw 31c is inserted into the locking hole 33c, the upright portion 33a returns to its original position. As a result, the upper outer peripheral end of the locking pawl 31c is covered with the upright portion 33a, and the opening/closing lid 31 is locked with the locking portion 33.

On the other hand, by pressing the operating portion 33b downward, the upright portion 33a is bent toward the outer circumference. At this time, the upper outer peripheral end of the locking pawl 31c is opened, and the locking of the locking pawl 31c by the locking portion 33 is released. When the locking part 33 is released, the protruding part 31b is pressed by the elastic force of the elastic member 32, and the opening/closing lid 31 is rotated upward. Thereby, the pop-up mechanism of the opening/closing lid 31 can be configured with a simple structure by the elastic member 32, the relief part 34, and the protruding part 31b. Therefore, it is possible to provide a storage container 1 that can improve manufacturing efficiency.

Furthermore, by forming the flexible outlet 32a with the elastic member 32 that covers the relief portion 34 that constitutes the pop-up mechanism, the number of parts can be reduced and manufacturing costs can be reduced. Moreover, manufacturing efficiency can be further improved.

FIG. 5 is an exploded perspective view of the lid part 20. The lid part 20 is assembled by sandwiching the elastic member 32 between the upper surface part 21 and the opening/closing lid 31.

The elastic member 32 has fixing holes 32c, 32d and an insertion hole 32b. Further, the connecting portion 31f of the opening/closing lid 31 has a lid protrusion 31e. Further, the upper surface portion 21 has an upper surface protrusion 23a, a holding hole 23d, an engagement hole 23c, and an engagement claw 23b.

A pair of upper surface projections 23a are arranged at both corners of the upper surface of the second recess 21b on the locking section 33 side, and are inserted into fixing holes 32c provided at a pair of corners of the elastic member 32. Thereby, the elastic member 32 can be easily positioned on the second recess 21b.

The engagement claw 23b extends from the periphery of the opening 30 toward the hinge portion 31a, and is bent toward the engagement hole 23c. The engagement hole 23c is arranged adjacent to the engagement claw 23b and opens on the locking portion 33 side of the upper surface of the first recess 21a. The engagement claw 23b is inserted into the insertion hole 32b of the elastic member 32, bent multiple times, and engaged with the engagement hole 23c (see FIG. 4). Thereby, the front part of the elastic member 32 is fixed to the upper surface part 21. At this time, the insertion hole 32b is arranged adjacent to the outlet 32a, and can prevent the periphery of the outlet 32a from being lifted up when taking out the wet tissue from the outlet 32a.

The holding holes 23d are opened at three locations on the outer peripheral portion of the upper surface of the first recess 21a, facing the locking portion 33 in the radial direction. The fixing holes 32d of the elastic member 32 are opened at three locations along the short side opposite to the insertion hole 32b. The lid protrusions 31e protrude from the lower surface of the connecting portion 31f at three locations. The holding hole 23d and the fixing hole 32d are stacked vertically, and the lid protrusion 31e of the opening/closing lid 31 is inserted from above. The lid protrusion 31e is engaged with the holding hole 23. Thereby, the rear part of the elastic member 32 is fixed while being held between the upper surface part 21 and the opening/closing lid 31. Therefore, the lid part 20 can be easily assembled by sandwiching the elastic member 32 between the upper surface part 21 and the opening/closing lid 31. Thereby, the manufacturing efficiency of the storage container 1 can be further improved.

According to this embodiment, the opening/closing lid 31 is locked by the locking part 33 with the protruding part 31b pressing the elastic member 32. At this time, the deformation of the elastic member 32 is released by the relief part 34 arranged on the upper surface part 21. By releasing the locking portion 33, the protruding portion 31b is pressed by the elastic force of the elastic member 32, and the opening/closing lid 31 is rotated upward. As a result, the pop-up mechanism of the opening/closing lid 31 can be configured with a simple structure by the elastic member 32, the relief part 34, and the protruding part 31. Therefore, it is possible to provide a storage container 1 that can improve manufacturing efficiency.

Further, the elastic member 32 covers the opening 30 and has an outlet 32a opening opposite to the opening 30 to take out the contents. The periphery of the outlet 32a formed by the elastic member 32 is easily deformed. Therefore, the contents can be easily pulled out without damaging them. Further, by forming the diameter of the outlet 32a smaller than that of the opening 30, drying of the contents can be reduced. Furthermore, by covering the opening 30 with the elastic member 32 that covers the escape portion 34, the number of parts can be reduced, manufacturing costs can be reduced, and manufacturing efficiency can be further improved.

Furthermore, the protrusion 31b enters the relief portion 34 when the opening/closing lid 31 closes the opening 30. As a result, the elastic member 32 is greatly deformed, and a stronger elastic force acts on the protrusion 31b. Therefore, when opening the lid, the opening/closing lid 31 becomes easier to stand up.

Moreover, the lid part 20 has an engagement claw 23b and an engagement hole 23c. The engaging claw 23b extends from the periphery of the opening 30 and is bendable. The engagement hole 23c is arranged adjacent to the engagement claw 23b and engages with the bent engagement claw 23b. The elastic member 32 has an insertion hole 32b that opens adjacent to the outlet 32a, and is fixed to the upper surface portion 21 by engaging the engagement claw 23b inserted into the insertion hole 32b with the engagement hole 23c. At this time, the insertion hole 32b is arranged adjacent to the outlet 32a, and can prevent the periphery of the outlet 32a from being lifted up when taking out the contents from the outlet 32a.

Further, the relief portion 34 is arranged closer to the hinge portion 31a than the opening portion 30. By arranging the relief portion 34 on the side of the hinge portion 31a, the opening/closing lid 31 can be closed with a small force while pressing the elastic member 32 with the protruding portion 31b using a lever action. Further, when the lid 31 is opened, it is pushed upward by the elastic member 32 at a position close to the hinge portion 31a, so that the lid 31 can be reliably popped up.

Further, the relief portion 34 is formed by recessing the upper surface of the lid portion 20 downward. Thereby, the airtightness around the relief portion 34 can be improved.

The above embodiments are merely illustrative of the present invention. The configuration of the embodiment may be modified as appropriate without departing from the technical idea of the present invention. Further, the embodiments may be implemented in combination to the extent possible.

For example, the insertion hole 32b may open integrally with the outlet 32a. Further, the relief portion 34 may be formed to penetrate the upper surface portion 21 or may be opened integrally with the opening portion 30.
