Description

[Technical field]

[0001] The present invention relates to a wet tissue container. [Background technology]

[0002] Generally, an openable / closable wet tissue container for storing wet tissues therein comprises a body for storing the wet tissues and having an outlet for dispensing the wet tissues, and an openable / closable lid for sealing the outlet so as to be openable / closable.

[0003] When using the device, the opening and closing lid is opened over the outlet of the main body, and the wet tissues are taken out one by one from the outlet of the main body.

[0004] As described above, conventional wet tissue containers comprise a main body and an opening / closing lid that is attached to the main body so that it can swing freely. When not in use, the opening / closing lid is closed to prevent the liquid components in the wet tissue inside the main body from evaporating.

[0005] For example, the wet wipes container disclosed in Patent Document 1 has a convex flat contact portion provided in the center of the back surface of the opening and closing part that contacts the periphery of the dispensing opening to seal the container.

[0006] [Patent Document 1] JP 2019-51945 A Summary of the Invention [Problem to be solved by the invention]

[0007] However, in a wet tissue container configured as in Patent Document 1, if the wet tissue is not properly pushed back into the outlet when the lid is closed, the wet tissue may become pinched between the periphery of the outlet and the abutment on the lid. In this case, the lid may not close to the specified position, or the lid and the main body may bend, making it difficult to adequately seal the wet tissue container and ensuring airtightness.

[0008] An object of the present invention is to provide a wet tissue container that can ensure airtightness even when wet tissues are sandwiched between the main body and the opening / closing lid. [Means for solving the problem]

Note that the figures shown below, including FIG. 1, are schematic diagrams, and the size and shape of each part are exaggerated or omitted as appropriate to facilitate understanding. In the following description, specific numerical values, shapes, materials, etc. are given, but these can be changed as appropriate. In the following description, the directions such as up / down (bottom), left / right, front / back, etc. shown in FIG. 1 will be used appropriately.

[0018] First, we will explain the overall configuration of the wet tissue container 1. As shown in Figures 1 to 8, the wet tissue container 1 includes a main body 10 with an opening 10a at the bottom that stores wet tissues 101 as the contents therein, and a bottom lid 60 that can seal the opening 10a of the main body 10 and can be detachably attached to the main body 10.

[0019] FIG. 9 is a plan view showing the main body 10. As shown in FIG. The main body 10 has an upper plate 11 in which an outlet 15 for taking out the wet tissues 101 is formed, and a side plate 12 extending downward from the upper plate 11. An opening / closing lid 20 for sealing the outlet 15 of the upper plate 11 is attached to the side plate 12 of the main body 10 so as to be able to swing freely around a swing shaft 24 on the base end 20a side.

[0020] An inwardly recessed rear step 16 is formed on the base end 20a side of the opening / closing lid 20 of the main body 10. The rear step 16 is provided with a storage portion 16a and rocking bearings 16b, 16b. One end of a rubber plate 40 (described later) is inserted into the storage portion 16a to store it therein. The swing shafts 24, 24 of the opening / closing cover 20 are rotatably fitted into the swing bearings 16b, 16b. A flange 12 a that abuts against a bottom cover 60 is formed on the lower part of the side plate 12 so as to protrude outward.

[0021] Moreover, the upper plate 11 of the main body 10 has a first upper plate 11a in the approximate center thereof, and a second upper plate 11b on the outer side of the first upper plate 11a and located higher than the first upper plate 11a.

[0022] A recess 13 is formed in the first upper plate 11a, and the outlet 15 is provided in the recess 13 of the first upper plate 11a. In this embodiment, the outlet 15 is an oval through-hole. The shape of the outlet 15 is not limited to an oval shape, and may be an ellipse or a circle, a rectangle or other polygon, or a complex shape with a partially narrowed width, or any other shape. Furthermore, an annular rib 14 is provided within this recess 13 to surround the outlet 15. That is, the above-mentioned outlet 15 is disposed within the area surrounded by the annular rib 14. This annular rib 14 has an inclined surface 14a on its outer side (the opposite side to the outlet 15) (see FIG. 17 described later). Around the entire periphery of the edge of the outlet 15, an edge rib 15a having an arc-shaped cross section and protruding outward from the main body 10 (upward in FIG. 8) is provided.

[0023] FIG. 10 is a view showing the inside surface of the opening / closing cover 20. As shown in FIG. Fig. 11 is a diagram showing the packing member 30. Fig. 11(a) is a diagram showing the packing member 30 as viewed from the side facing the outlet 15, and Fig. 11(b) is a cross-sectional view of the packing member 30 cut at the position of the arrow CC in Fig. 11(a). A frame 22 is formed on the back surface of the opening / closing lid 20, inside which the packing member 30 is attached. The frame 22 is adapted to fit inside the recess 13 and outside the annular rib 14 when the opening / closing lid 20 is closed.

[0024] As described above, the dome-shaped packing member 30 is attached inside the frame 22. This packing member 30 is constructed separately from the opening / closing lid 20. The packing member 30 is made of a soft synthetic resin material having elasticity, such as low-density polyethylene (LDPE), elastomer, silicone rubber, or the like, and is removably fitted into the frame 22.

[0025] The packing member 30 has a packing central portion 30a formed in a substantially elliptical shape in a plan view, and a packing outer peripheral portion 30b provided on the outer periphery of the packing central portion 30a and elastically movable in the vertical direction relative to the packing central portion 30a.

[0026] An inner rib 30c is formed between the packing central portion 30a and the packing outer peripheral portion 30b. The inner rib 30c extends vertically, and its upper end abuts against the rear surface of the opening / closing cover 20 (see Figs. 7 and 8). On the other hand, an annular recess 30d having a ring shape in a plan view is formed on the lower end side of the inner rib 30c.

[0027] An outer rib 30e is formed along the outer periphery of the packing outer periphery 30b. This outer rib 30e extends vertically upward from the packing outer periphery 30b, and its upper end is spaced apart from the back surface of the opening / closing lid 20 (see Figs. 7 and 8). A first engagement protrusion 30f is provided on the outer periphery of the outer rib 30e. The first engagement protrusion 30f is engaged with a second engagement protrusion 22a provided on the inner periphery of the frame 22, whereby the packing member 30 is detachably fitted into the frame 22.

[0028] On the other hand, a lower rib (adhering portion) 31 is provided below the packing outer periphery 30b. This lower rib 31 extends downward from the packing outer periphery 30b and has a ring shape when viewed from the bottom side. When the opening / closing cover 20 is closed, the lower rib 31 is adapted to be in close contact with the periphery of the outlet 15 of the main body 10. Specifically, the lower rib 31 is adapted to be in close contact with the annular rib 14 formed to surround the outlet 15 of the first upper plate 11a and with a portion of the recess 13.

[0029] 2 and 10, a locking piece 21 is provided at the free end 20e of the opening / closing cover 20. An operating member placement section 17 that drops down from the upper plate 11 is formed in the main body 10 on the side of the free end 20e of the opening / closing cover 20 and near the upper end of the side plate 12, and an operating member 50 is provided within this operating member placement section 17.

[0030] Fig. 12 is a diagram showing the operating member 50. Fig. 12(a) is a plan view of the operating member 50, Fig. 12(b) is a front view of the operating member 50, Fig. 12(c) is a bottom view of the operating member 50, Fig. 12(d) is a side view of the operating member 50, and Fig. 12(e) is a cross-sectional view of the operating member 50 taken at the position of the arrow DD in Fig. 12(b). The operating member 50 is attached to the operating member placement portion 17 of the main body 10 .

[0031] The operating member 50 has a top plate portion 51 on which an operating surface 51a is formed for a user to place his / her finger. This operating surface 51a is formed to form a curved surface with a concave center. A claw portion 52 for engaging with the locking piece 21 of the opening / closing cover 20 is formed in the center of the rear end portion of the top plate portion 51 (the upper side in FIG. 12(a)). In addition, support pieces 53, 53 for supporting the opening / closing cover 20 from below are arranged on the left and right of the claw portion 52 at the rear end portion of the top plate portion 51.

[0032] A pair of mounting ribs 54, 54 are provided on the back surface of the top plate 51 so as to protrude downward, and hinge shafts 55, 55 are formed on the mounting ribs 54, 54 so as to protrude in the left-right direction. The hinge shafts 55, 55 are coaxial with each other. Furthermore, a bow-shaped spring portion 56 is formed on the front end side of the back surface of the top plate 51.

[0033] The operating member 50 also has an operating member protrusion 57 that protrudes downward on the back surface side of the top plate 51 at a position hidden by the operating member 50 when viewed from above.

[0034] The operation member placement portion 17 of the main body 10 includes a bottom plate 17a, a main body protrusion portion 17b, a partition wall portion 17c, a hinge receiving hole 17d, and a spring receiving groove 17e. The bottom plate 17a is provided at a lower position than the first upper plate 11a and the second upper plate 11b. The main body protrusion 17b is located at a position hidden by the operating member 50 and protrudes upward from the bottom plate 17a. The partition wall 17c divides the bottom plate 17a into a front and a rear portion, and the front area of ​​the bottom plate 17a forms a spring receiving groove 17e. The spring portion 56 of the operating member 50 is disposed in the spring receiving groove 17e. The hinge receiving holes 17d, 17d are arranged on both the left and right ends of the operation member placement portion 17, and receive the hinge shafts 55, 55 of the operation member 50, respectively.

[0035] The operating member 50 is provided in the operating member mounting portion 17 so as to be freely swingable about the hinge shafts 55, 55 as a swing shaft, by placing the spring portion 56 in the spring receiving groove 17e and fitting the hinge shafts 55, 55 into the hinge receiving holes 17d, 17d, respectively. The operating member 50 can swing between a restricting position (shown by a solid line in FIG. 8) in which it engages with the opening / closing lid 20 to restrict the opening / closing lid 20 to a closed position, and a releasing position (shown in part by a dotted line in FIG. 8) in which it releases the engagement with the opening / closing lid 20. 8 (toward the restricted position) about the hinge shaft 55 due to the restoring force of the spring portion 56. Therefore, the claw portion 52 of the operating member 50 is biased in a direction approaching the recessed portion 13 about the hinge shaft 55.

[0036] When the opening / closing cover 20 is closed, the operating member 50 rotates so as to avoid the locking piece 21 of the opening / closing cover 20. Then, when the locking piece 21 climbs over the claw portion 52, the operating member 50 rotates by the force of the spring portion 56, whereby the locking piece 21 and the claw portion 52 mesh with each other, and the opening / closing cover 20 is held in the closed state. Furthermore, when the opening / closing cover 20 is in the closed state, the support pieces 53, 53 support the free end 20e of the opening / closing cover 20 from below.

[0037] On the other hand, when the user presses the operating surface 51a of the operating member 50 with the opening / closing lid 20 closed, the claw portion 52 of the operating member 50 rotates about the hinge shafts 55, 55 in a direction away from the recess 13, thereby disengaging the locking piece 21 from the claw portion 52. At this time, the support pieces 53, 53 of the operating member 50, in addition to moving in a direction away from the free end 20e of the opening / closing lid 20, also move in a direction pushing the free end 20e from below to above, thereby assisting in the disengagement of the locking piece 21 from the claw portion 52.

[0038] 2 and 8, an elongated rubber plate (lid biasing portion) 40 that biases the opening / closing lid 20 in the opening direction is provided between the main body 10 and the opening / closing lid 20. That is, the main body 10 is provided with a storage portion 16a in which one end of the rubber plate 40 is inserted downward to store it, and the opening / closing lid 20 is provided with a fixing portion 41 that fixes the other end of the rubber plate 40 in the horizontal direction.

[0039] FIG. 13 is a perspective view of the bottom cover 60 in the first state as viewed obliquely from above. FIG. 14 is a perspective view of the bottom cover 60 in the first state as viewed obliquely from below. FIG. 15 is a partial cross-sectional front view of the bottom cover 60 in the first state. The bottom cover 60 is a substantially rectangular member having a shape capable of closing the opening 10a of the main body 10, and is formed by a one-piece resin molding. An outer peripheral edge fitting portion 62 for fitting the bottom cover 60 to the opening 10a of the main body 10 is disposed on an outer peripheral edge portion 61 of the bottom cover 60. The outer peripheral edge fitting portion 62 of the bottom cover 60 includes a fitting groove 63 into which the edge portion 12b of the side plate 12 of the main body 10 that forms the lower opening 10a of the main body 10 fits, and a fitting protrusion 64 that protrudes upward within the main body 10 adjacent to the inside of the fitting groove 63 in a plan view of the bottom cover 60. With this configuration, the outer peripheral edge fitting portion 62 is disposed on the outer periphery of the bottom cover 60 surrounding the periphery of the flat plate portion 65, and fits into the edge portion 12b of the opening 10a by clamping it from both the inner wall side and the outer wall side of the main body 10. In the illustrated example, the fitting grooves 63 are disposed continuously along the outer periphery of the bottom cover 60, but the fitting grooves 63 may also be disposed discontinuously along the outer periphery of the bottom cover 60.

[0040] The fitting protrusion 64 is provided along the inner wall of the main body 10, continuing from the portion of the outer peripheral edge fitting portion 62 that abuts against the inner wall of the main body 10, and protrudes from the flat portion 65 toward the inward side of the main body 10 at a first height h1, and fits into the inner wall of the main body 10. The fitting protrusion 64 is provided in a substantially rectangular shape corresponding to the shape of the opening 10a at the bottom of the main body 10. At the four corners of the fitting protrusion 64, low protrusions 64a are provided, which protrude from the flat plate portion 65 toward the inside of the main body 10 at a second height h2 that is lower than the first height h1.

[0041] 13 to 15, the bottom cover 60 can be transformed into a second state in which the central protrusion 601 is lifted up toward the inside of the main body. The second state and the configuration related to this second state will be described later.

[0042] The main body 10 and the opening / closing cover 20 are both obtained by injection molding using polypropylene (PP), but may also be molded using PE, PS, ABS, elastomer, PET, PVC, or polycarbonate. The bottom cover 60 is preferably made of linear low density polyethylene (LLDPE), and silicone rubber is used as the rubber plate 40. The fixing portion 41 is made of polypropylene (PP).

[0043] FIG. 16 is a side cross-sectional view showing a sealed bag 100 containing wet tissues 101. As shown in FIG. 16(a), the wet tissues 101 are folded and stacked in a sealed bag 100 made of a flexible sheet, and are sealed by the sealed bag 100. Each wet tissue 101 is folded approximately in half with a folding portion 102 formed, and the folding portions 102 of each wet tissue 101 are alternately alternating. The folded lower half 101b of the wet tissue 101 is inserted between the upper half 101a of the wet tissue 101 located below and the upper half 101a of the wet tissue 101 located further below. Therefore, when the wet tissues 101 are picked up one by one and taken out, the lower half 101b of the taken out wet tissue 101 pulls up the upper half 101a of the wet tissue 101 located below. The way in which the wet tissues 101 are folded is not particularly limited as long as they are stacked so that they can be taken out continuously, and may be, for example, a folding method as shown in FIG. 16(b). An opening 100a is provided at the upper end of the sealed bag 100, and this opening 100a is sealed by a lid piece 105 that is detachably attached to the upper surface of the sealed bag 100.

[0044] The wet tissue 101 may be made of, for example, a fibrous material such as nonwoven fabric, paper, or gauze, a sheet-like foam, or a paper-based soft material. Possible liquids to be impregnated into the wet tissue 101 include moisturizing agents containing germicides, disinfectants, cleaning agents, etc., and cosmetics such as lotions and milky lotions. In this embodiment, the sealing performance between the main body 10 and the opening / closing lid 20 is improved, so that wet tissues 101 impregnated with a highly volatile liquid such as alcohol can be preferably used. In this embodiment, the wet tissue 101 is impregnated with alcohol.

[0045] Next, the characteristic features of this embodiment having the above-mentioned configuration will be described. To facilitate understanding of the following description, FIG. FIG. 17 is a partially enlarged cross-sectional view of the upper part of FIG. 8, and a corresponding enlarged view of the packing member 30. As shown in FIG.

[0046] (Length of lower rib 31) When using the wet tissue 101, the user first presses the top plate portion 51 of the operating member 50. This disengages the locking piece 21 from the claw portion 52. In this case, the restoring force of the rubber plate 40 opens the opening / closing cover 20.

[0047] That is, the opening / closing cover 20 is biased by the rubber plate 40 and rotates in the opening direction (clockwise in Figs. 8 and 17) around the swing shaft 24. When the opening / closing cover 20 subsequently reaches the fully open position, the base end 20a of the opening / closing cover 20 abuts against the main body 10 and the opening / closing cover 20 stops.

[0048] Next, the wet tissue 101 is picked up with the fingers and pulled upward from the outlet 15 of the main body 10 for use.

[0049] After the wet tissue 101 is removed in this manner, the opening / closing lid 20 is closed. At this time, the user presses the opening / closing lid 20 downward with his or her hand, causing the opening / closing lid 20 to rotate in the closing direction (counterclockwise in Figs. 8 and 17) about the swing shaft 24 against the biasing force of the rubber plate 40. Thereafter, when the opening / closing lid 20 reaches the fully closed position, the locking piece 21 of the opening / closing lid 20 engages with the claw portion 52 of the operating member 50, and the opening / closing lid 20 is fixed in the fully closed position.

[0050] During this time, as shown in FIG. 17, the lower rib 31 of the packing member 30 rises along the inclined surface 14a of the annular rib 14. That is, as described above, the packing member 30 is made of an elastic material, and the packing outer periphery 30b and the lower rib 31 are elastically movable in the vertical direction together. Therefore, when the opening and closing cover 20 is closed, when the lower rib 31 abuts against the inclined surface 14a of the annular rib 14, the packing outer periphery 30b is deformed upward, and the contact position of the lower rib 31 with the inclined surface 14a rises relative to the packing member 30. In this case, the lower rib 31 is pressed against the inclined surface 14a by the restoring force of the packing outer periphery 30b, so that the lower rib 31 and the inclined surface 14a are in close contact with each other. In this way, the packing member 30 seals the outlet 15 of the main body 10.

[0051] Here, if all of the lower ribs 31 of the packing member 30 are configured to be sufficiently long, the repulsion due to the elastic body of the packing member 30 is large, so the operating force required to close the opening / closing lid 20 is large, and it may be difficult to close it. Also, because the repulsion due to the elastic body of the packing member 30 is large, the lower ribs 31 and the periphery of the outlet 15 may bite into each other at the contact portion, and the opening / closing lid 20 may not be opened by the biasing force that biases it in the opening direction alone. Therefore, in this embodiment, the downward protruding length of the lower rib (contact portion) 31 is gradually changed so that the length is longer on the side closer to the oscillation shaft 24 than on the side farther from the oscillation shaft 24. Specifically, as shown in Fig. 17(b), the height difference dh between the tip positions of the most protruding position on the side closest to the oscillation shaft 24 of the lower rib 31 and the least protruding position on the side farthest from the oscillation shaft 24 is 1.6 mm.

[0052] The portion of the lower rib 31 closer to the oscillating axis 24 is in close contact with the inclined surface 14a and the flat surface of the recess 13, and by gradually shortening the downward protruding length of the lower rib 31 as it moves away from the oscillating axis 24, it is in close contact with only the inclined surface 14a. The part furthest from the pivot shaft 24, which is the part that can be reliably held down by the operating member 50, has the shortest downward projection length of the lower rib 31, and is in close contact with only the inclined surface 14a. This makes it easier for the opening / closing cover 20 to open by the biasing force of the rubber plate 40 alone when the operating member 50 is pushed in to release the engagement between the operating member 50 and the opening / closing cover 20. Conversely, on the side closer to the oscillation shaft 24, the inclined surface 14a and the flat surface of the recess 13 are tightly attached to each other to increase airtightness.

[0053] It is preferable that the height difference dh of the tip position is 1 mm or more in order to ensure the airtightness of the wet tissue container 1. It is also preferable that the height difference dh of the tip position is 2.5 mm or less in order to make it easy to open and close the opening / closing lid 20.

[0054] In this embodiment, the height difference dh is 1.6 mm as described above, so that the opening and closing lid 20 can be opened and closed easily while ensuring the airtightness of the wet tissue container 1. Furthermore, in this embodiment, the lower rib 31 abuts against the inclined surface 14a of the annular rib 14. This weakens the force with which the lower rib 31 abuts against the inclined surface 14a, thereby reducing the force required to close the opening / closing cover 20. Furthermore, the lower rib 31 can be prevented from sticking to the inclined surface 14a, allowing the opening / closing cover 20 to be opened easily.

[0055] (Distance between the periphery of the outlet 15 and the packing member 30) Furthermore, in conventional wet tissue containers, if the wet tissue is not properly pushed back into the outlet when the lid is closed, the wet tissue may become pinched between the periphery of the outlet and the abutment on the lid. In this case, the lid may not close to the specified position, or the lid and the main body may bend, making it difficult to adequately seal the wet tissue container and ensuring airtightness. Therefore, in the wet tissue container 1 of this embodiment, when the opening / closing lid 20 is in the closed position, the minimum distance S (see FIG. 17) between the edge rib 15a on the periphery of the outlet 15 and the packing member 30 is set to be 0.3 mm or more. This minimum distance S of 0.3 mm is equivalent to the thickness of one wet tissue 101, which is 0.3 mm. Therefore, even if the wet tissue remaining protruding from the outlet 15 becomes pinched between the periphery of the outlet 15 and the packing member 30, the airtightness of the wet tissue container 1 can be sufficiently ensured. Furthermore, it is preferable that the minimum distance S is 1.5 mm or less, since this reduces unnecessary space, from the viewpoint of preventing the wet tissue container from drying out.

[0056] In this embodiment, when the opening / closing lid 20 is in the closed position, the minimum distance S between the edge rib 15a of the periphery of the outlet 15 and the packing member 30 is 0.2 mm or more at all positions. However, the wet tissue 101 is often pulled out toward the front side of the wet tissue container 1, i.e., toward the swing shaft 24. In addition, since the opening / closing lid 20 rotates around the swing shaft 24, when the opening / closing lid 20 is closed, the wet tissue 101 protruding from the outlet 15 is pushed forward (to the side farther from the swing shaft 24). Therefore, when the opening / closing lid 20 is in the closed position, if the minimum distance between at least the half circumference of the periphery of the outlet 15 farther from the swing shaft 24 and the packing member 30 is 0.3 mm or more, it is possible to prevent the wet tissue from being strongly pinched between the periphery of the outlet and the abutment on the opening / closing lid side.

[0057] (Prevention of falling of the operating member 50) Furthermore, the wet tissue container 1 of this embodiment is provided with an operating member 50 so that the opening / closing lid 20 can be opened with one hand. As described above, this operating member 50 is biased by the spring portion 56 toward the restricted position (shown by a solid line in FIG. 17), and can swing between the restricted position and the released position (partially shown by a two-dot chain line in FIG. 17).

[0058] In the wet tissue container 1 of this embodiment, as shown in Fig. 3, the end of the operating member 50 on the opening / closing lid 20 side is disposed opposite the free end 20e of the opening / closing lid 20. Therefore, a configuration for restricting the position of the operating member 50 cannot be configured on the main body 10 at the end of the operating member 50 on the opening / closing lid 20 side. If no configuration for restricting the position of the operating member 50 is provided, when the opening / closing lid 20 is open, the operating member 50 will exceed the restricted position and will be significantly tilted in the clockwise direction in Fig. 17 due to the biasing force of the spring portion 56.

[0059] Therefore, in this embodiment, the main body 10 is provided with a main body protrusion 17b that protrudes upward from the bottom plate 17a at a position hidden by the operating member 50. The operating member 50 is also provided with an operating member protrusion 57 that protrudes downward on the back side of the top plate 51 at a position hidden by the operating member 50 when viewed from the top side. When the opening / closing lid 20 is in the open state, the operating member protrusion 57 abuts against the main body protrusion 17b, thereby restricting the movement of the operating member 50 in the direction of the restricted position, and preventing the operating member 50 from falling over too far beyond the restricted position.

[0060] (Lift up bottom cover 60) Furthermore, the wet tissue container 1 of this embodiment is configured to be capable of storing a larger number of wet tissues 101 (for example, about 100 sheets) than conventionally. Therefore, the length of the side plate 12 of the main body 10 (the height of the main body 10) is configured to be longer than conventionally. Even with conventional wet tissue containers, it can be difficult to remove wet tissues when the amount of wet tissues remaining is low. In particular, when the open / close lid is closed when there are only a few wet tissues remaining, the wet tissues may return to the inside beyond the outlet, requiring the user to insert their fingers from the outlet to the bottom of the container to pick up the wet tissues, which can be inconvenient to use. Furthermore, since the wet tissue container 1 of this embodiment is capable of storing a greater number of wet tissues 101 than conventional containers, the depth from the outlet 15 to the bottom of the container is greater. With a configuration similar to that of conventional containers, it is expected that it will be difficult to remove wet tissues when only a few are left.

[0061] Therefore, the bottom cover 60 of this embodiment is capable of transforming from the first state shown in Figs. 13 to 15 to a second state in which the central protrusion 601 is lifted up toward the inside of the main body. FIG. 18 is a perspective view of the bottom cover 60 in the second state as viewed obliquely from above. Fig. 19 is a diagram showing cross sections of the bottom cover 60 in a first state and a second state side by side. Fig. 19(a) is a cross section of the bottom cover in the first state taken along the position of the arrow EE in Fig. 13, and Fig. 19(b) is a cross section of the bottom cover in the second state taken along the position of the arrow FF in Fig. 18.

[0062] The bottom cover 60 includes an expandable portion 600 near the center of the bottom cover 60 to enable deformation between a first state and a second state. The flat plate portion 65 is a flat portion provided around the extension portion 600 .

[0063] The expandable portion 600 is provided at approximately the center of the flat plate portion 65, and is configured to be deformable from a first state in which it protrudes to a first height hs1 (see FIG. 19(a)) toward the inside of the main body 10 to a second state in which it protrudes to a second height hs2 (see FIG. 19(b)) higher than the first height toward the inside of the main body 10. Note that the first height hs1 and the second height hs2 are both the heights from the surface of the flat plate portion 65 (the surface on the inside of the main body 10) to the surface of the planar portion 601a (the surface on the inside of the main body 10) described below. More specifically, the expansion / contraction portion 600 is composed of a central protrusion portion 601 having an approximately circular shape when viewed from above, a central wall portion 602, a central flat surface 603, a first peripheral wall portion 604, and a second peripheral wall portion 605.

[0064] The central protrusion 601 protrudes inwardly of the main body 10 (upward in FIG. 19), and has a planar portion 601a formed of a curved surface, and a plurality of rib portions 601b arranged radially from the planar portion 601a. ​​The planar portion 601a may be a flat surface instead of a curved surface. By configuring the central protrusion 601 by combining the planar portion 601a and the rib portion 601b, sufficient strength can be ensured without making the central protrusion 601 thick. In addition, the area for supporting the sealed bag 100 (wet tissue 101) can be enlarged, and the sealed bag 100 (wet tissue 101) can be stably supported, particularly in the second state described below.

[0065] The central wall portion 602 is connected to the outer periphery of the central protrusion portion 601 so as to surround the central protrusion portion 601, and extends in the up-down direction (approximately vertical direction).

[0066] The central flat surface 603 is connected to the central wall portion 602 so as to surround the central wall portion 602, and is configured as a surface approximately parallel to the flat plate portion 65. Furthermore, on the outer side of the main body 10 (the lower side in FIG. 19), the central flat surface 603 is approximately flush with the lowermost part of the outer edge of the bottom cover. This configuration can improve the stability when the wet tissue container 1 is placed. Note that the same effect can be obtained even if the central flat surface 603 is configured to be approximately flush with the flat plate portion 65. Furthermore, by providing the central flat surface 603 and the rib portion 601b, strength can be ensured when deformed into the second state, and even when a large number of wet tissues 101 are stored or when the wet tissues 101 have absorbed a large amount of liquid, the container will not return to the first state due to the weight of the wet tissues 101. Furthermore, by providing the central flat surface 603 and the rib portion 601b, the strength of the wet tissue container 1 is less likely to decrease even with repeated use, and the durability of the wet tissue container 1 can be increased.

[0067] The central protrusion 601, the central wall 602, and the central flat surface 603 are parts that move together with little deformation in both the first state and the second state, and are collectively referred to as the central portion 610. This central portion 610 is pressed by a finger or the like when the expandable portion 600 is transformed from the first state to the second state, and when the expandable portion 600 is transformed in the opposite direction.

[0068] The first peripheral wall portion 604 is configured in a ring shape surrounding the central portion 610, and in the first state, the end portion (inner edge) of the first peripheral wall portion 604 on the central portion 610 side is an inclined surface that is lower (closer to the outside of the main body 10) than the end portion (outer edge) on the opposite side, and connects between the central flat surface 603 and the second peripheral wall portion 605. That is, in the first state, the first peripheral wall portion 604 has a shape that corresponds to the inner surface shape of a truncated cone with the end portion (inner edge) on the central portion 610 side being the smaller diameter side. Moreover, in the second state, the first peripheral wall portion 604 is an inclined surface that is inclined so that the end portion (inner edge) of the first peripheral wall portion 604 on the central portion 610 side is higher (closer to the inner side of the main body 10) than the end portion (outer edge) on the opposite side, and connects between the central flat surface 603 and the second peripheral wall portion 605. That is, in the second state, the first peripheral wall portion 604 has a shape that corresponds to the outer surface shape of a truncated cone with the end portion (inner edge) on the central portion 610 side being the smaller diameter side.

[0069] The second peripheral wall portion 605 surrounds the first peripheral wall portion 604, and in the first state is connected to the inner peripheral edge of the first peripheral wall portion 604 on the main body 10 and to the flat plate portion 65.

[0070] Here, a method of transforming the telescopic part 600 configured as described above between the first state and the second state will be described. When transforming the telescopic part 600 from the first state to the second state, the transformation may be performed with the bottom cover 60 attached to the main body 10, or with the bottom cover 60 removed from the main body 10. When transforming the telescopic part 600 from the second state to the first state, the transformation is performed with the bottom cover 60 removed from the main body 10.

[0071] First, when the telescopic part 600 is transformed from the first state shown in FIG. 19(a) to the second state shown in FIG. 19(b), a pressing force is applied to the outer surface of the central part 610 located at the center of the telescopic part 600 with a finger or the like in the direction of the arrow shown in FIG. 19(a) while holding the periphery of the bottom cover 60 or the main body 10. The pressing force applied to the central part 610 pushes the central part 610 (the central protruding part 601, the central wall part 602, the central flat surface 603) and the first peripheral wall part 604 up toward the inside of the main body 10, transforming it to the second state. In this second state, as shown in FIG. 19(b), the first peripheral wall part 604 is inverted with the connection part between the central flat surface 603 and the first peripheral wall part 604 and the connection part between the first peripheral wall part 604 and the second peripheral wall part 605 as fulcrums. In other words, the connection portion between the central flat surface 603 and the first peripheral wall portion 604 is raised toward the inside of the main body 10. In this way, by pushing the central portion 610 inward of the main body 10, the expandable portion 600 can be expanded and deformed to a second state in which it protrudes to a second height, as shown in Fig. 19(b). After deformation, the expandable portion 600 does not naturally return to the first state, but is maintained in the second state.

[0072] Next, when the expandable portion 600 is transformed from the second state shown in FIG. 19(b) to the first state shown in FIG. 19(a), a pressing force is applied to the center portion 610 by hand or the like in the direction of the arrow shown in FIG. 19(b) while holding the outer surface of the bottom cover 60. The pressing force applied to the center portion 610 pushes down the center portion 610 (the central protruding portion 601, the central wall portion 602, the central flat surface 603) and the first peripheral wall portion 604, transforming them into the first state. In this first state, as shown in FIG. 19(a), the first peripheral wall portion 604 is again inverted with the connection portion between the central flat surface 603 and the first peripheral wall portion 604 and the connection portion between the first peripheral wall portion 604 and the second peripheral wall portion 605 as fulcrums. In this manner, by pushing down the central portion 610, the expandable portion 600 can be contracted and returned to the first state in which it protrudes to the first height, as shown in FIG. 19(a).

[0073] Here, in order to facilitate deformation of the expandable portion 600 and to make the central portion 610 less likely to deform, it is preferable that the first peripheral wall portion 604 is formed thinner than the central flat surface 603. As an example, the thickness of the central flat surface 603 is 1 mm to 2 mm, and the thickness of the first peripheral wall portion 604 is 0.5 mm to 1 mm. The thicknesses of the planar portion 601a, the central wall portion 602, and the second peripheral wall portion 605 are not particularly limited as long as they can maintain their respective shapes.

[0074] According to the wet tissue container 1 of this embodiment, by extending the expandable part 600 provided on the bottom cover 60 to the second state, the bottom can be raised as shown in Fig. 19(b), making it easy to remove the wet tissues 101. Furthermore, when the wet tissues 101 inside the main body 10 have been used up, the expandable part 600 can be contracted again to the first state to refill with a larger number of new sealed bags 100 (wet tissues 101).

[0075] Furthermore, the bottom cover 60 has no slits or openings, and the extendable part 600 can be transformed between the first state and the second state without impairing the airtightness of the bottom cover 60. Therefore, the wet tissue container 1 of this embodiment can maintain a sealed state regardless of the deformed state of the extendable part 600.

[0076] In addition, in this embodiment, the central protrusion 601 and the center portion 610 that constitute the expansion / contraction portion 600 are approximately circular, and the first peripheral wall portion 604 and the second peripheral wall portion 605 are concentric with the central protrusion 601 and the center portion 610, but the shapes of the central protrusion 601 and the center portion 610, the first peripheral wall portion 604, and the second peripheral wall portion 605 may be other than concentric.

[0077] (Low protrusion 64a) Furthermore, in the wet tissue container 1 of this embodiment, the fitting protrusion 64 of the bottom cover 60 is fitted deep into the main body 10, thereby improving the airtightness of the wet tissue container 1. In this embodiment, the higher the fitting protrusion 64 (the amount of protrusion into the main body 10), the better the airtightness can be expected. That is, since the bottom cover 60 is formed from an elastic resin, the rigidity of the bottom cover 60 can be increased by making the fitting protrusion taller, which has the effect of suppressing deformation of the bottom cover 60, thereby contributing to improved airtightness. However, if the height of the fitting projection is increased, there is a risk that it will become difficult to open the bottom cover.

[0078] Therefore, in the wet tissue container 1 of this embodiment, the four corners of the fitting protrusion 64 of the bottom cover 60 are provided with low protruding parts 64a, which protrude from the flat plate part 65 toward the inside of the main body 10 at a second height h2 lower than the first height h1. Specifically, the first height h1 is set to 12.8 mm and the second height h2 is set to 9.2 mm as shown in FIG. 15. In addition, a hook piece 60a protruding outward is provided at one of the four corners of the bottom cover 60. This increases the possibility that the bottom cover 60 will be removed from the main body 10 from the corner where the hook piece 60a is provided. In addition, the low protruding parts 64a are provided at the four corners of the bottom cover 60, and the fitting amount (fitting depth) between the main body 10 and the low protruding parts 64a is small, so that it is easy to start removing the bottom cover 60. If the bottom cover 60 can be removed from the main body 10 to some extent, the subsequent removal work can be performed relatively easily. Therefore, by providing the low protruding portion 64a, the operation of removing the bottom cover 60 from the main body 10 can be easily performed.

[0079] Here, it is desirable for the second height h2 to be 10 mm or less in order to facilitate the operation of removing the bottom cover 60 from the main body 10. Moreover, it is desirable that the second height h2 be 5 mm or more in order to ensure the rigidity of the four corners of the bottom cover 60 and to prevent a decrease in the airtightness. Furthermore, in order to facilitate the operation of removing the bottom cover 60 from the main body 10, it is desirable that the range L (see FIGS. 13 and 15) in which the low protrusion portion 64a is provided is 5 mm or more. Furthermore, it is desirable that the range L in which the low protrusions 64a are provided be within 25 mm in order to ensure the rigidity of the four corners of the bottom cover 60 and to prevent a decrease in the airtightness. The dimension of range L is the dimension of the range that starts from the center position of the top of the low protrusion portion 64a located on the other side that intersects at the corner as shown in Figures 13 and 15, and reaches the second height h2.

[0080] In addition, since the four corners of the bottom cover 60 are positions where two perpendicular sides intersect, these corners are more rigid than the areas near the center of the four sides of the bottom cover 60, and the reduction in rigidity at the four corners due to the provision of the low protrusion portions 64a does not adversely affect the airtightness. The low protrusions 64a do not have to be provided at all four corners as in the present embodiment, but may be provided at at least one of the four corners. For example, the low protrusions 64a may be provided only at the corners where the hook pieces 60a are provided.

[0081] The fitting projection 64 has a belt-shaped protrusion 64b that protrudes continuously around the entire periphery on the wall surface that abuts against the inner wall of the main body 10 toward the inner wall side of the main body 10. The belt-shaped protrusion 64b is also provided continuously on the wall surface of the low protrusion portion 64a. If the outer wall surface of the fitting protrusion 64 and the inner wall surface of the main body 10 were fitted together without providing the belt-shaped protrusion 64b, the contact area would be large, requiring a large force to remove and attach the bottom lid 60, making the removal process difficult. On the other hand, in the wet tissue container 1 of this embodiment, the belt-shaped protrusion 64b is provided, so the contact area between the bottom lid 60 and the main body 10 is smaller, making it even easier to remove the bottom lid 60.

[0082] (Variations) The present invention is not limited to the above-described embodiment, and various modifications and variations are possible, and these are also within the scope of the present invention.

[0083] (1) In the embodiment, an example was described in which a rubber plate 40 was provided as the lid biasing portion. However, the lid biasing portion is not limited to this, and may be a spring member made of another type of elastic body such as metal, or may be configured as a lid biasing portion that biases the opening / closing lid by elastically deforming a part of the opening / closing lid or the main body.

[0084] (2) In the embodiment, an example has been described in which the wet tissue 101 is impregnated with alcohol. However, the present invention is not limited to this, and the wet tissue 101 may be impregnated with other liquids, such as a moisturizer containing a bactericide, disinfectant, or cleaner, or cosmetics such as lotion or milky lotion.

[0085] (3) In the embodiment, the wet tissue container 1 is configured to be capable of storing a greater number of wet tissues 101 than conventionally, and the length of the side panel 12 of the main body 10 (the height of the main body 10) is greater than conventionally. However, the present invention is not limited to this, and the container may be configured to be capable of storing approximately the same number of wet tissues 101 as conventionally, or may be configured to store a smaller number of wet tissues 101 than conventionally.
