Abstract
Description
[Technical Field]
[0001] The present disclosure relates to a wet tissue storage container and a wet tissue storage body. [Background technology]
[0002] There is a wet tissue storage container that stores a removable roll of wet tissues with easy-to-tear sections such as perforations at predetermined intervals in the longitudinal direction. In the wet tissue storage container, a pull-out opening is provided in the lid for pulling out the wet tissues, and the pull-out resistance (frictional resistance) between this pull-out opening and the wet tissues cuts the easy-to-tear sections, allowing the wet tissues to be taken out one by one.
[0003] For example, Patent Document 1 discloses a wet tissue storage container. This wet tissue storage container has a generally cylindrical shape overall and includes a container body that stores a roll of wet tissues, and a lid. The wet tissue roll has perforations formed at predetermined intervals in the longitudinal direction of the sheet body. The container body is generally cylindrical with a bottom and an opening at the upper end, and a male thread portion is formed circumferentially on the outer periphery of the upper end of the container body. The lid is cylindrical with an open lower end, and a female thread portion is formed circumferentially on the inner surface of the lower end that screws into the male thread portion of the container body, so that the lid can be detachably fitted into the opening of the container body. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-216116 Summary of the Invention [Problem to be solved by the invention]
[0005] In the wet tissue storage container described in Patent Document 1, the container body and the lid are detachably attached by a male screw portion and a female screw portion, so when opening and closing the lid, such as when refilling the wet tissue roll, there are problems such as it being too tightly fastened and taking a long time to open, or being too tightly fastened and the lid spinning freely.On the other hand, there is also the problem of the lid opening too easily.
[0006] Furthermore, in order to ensure the aesthetic appeal of the wet tissue storage container, if the side of the container body and the side of the lid are arranged on the same plane, as in the wet tissue storage container described in Patent Document 1, the area below the male thread portion of the container body needs to be expanded in diameter to fit the side of the lid. As a result, in the wet tissue storage container described in Patent Document 1, the container body is larger than the roll of wet tissues inside, reducing the compactness of the wet tissue storage container. On the other hand, if the area below the male thread portion of the container body is made the same diameter as the male thread portion in order to ensure compactness, the side of the container body and the side of the lid cannot be arranged on the same plane, reducing the aesthetic appeal.
[0007] Therefore, an object of the present disclosure is to provide a wet tissue storage container and a wet tissue storage body that improve the ease of opening and closing the lid body, and that can achieve both compactness and elegance. [Means for solving the problem]
[0008] In order to solve the above problem, a first aspect of the wet tissue storage container of the present invention has a rectangular upper end opening and a container side locking portion formed circumferentially on the inner surface of the upper end, defining a storage space inside which can store a roll of wet tissues, and comprises a container body formed with a rectangular cross section, a rectangular top plate, an outlet provided on the top plate through which the wet tissues can be removed, an insertion portion extending downward from the top plate and inserted into the container body from the upper end opening to fit into the container body, and a lid side locking portion formed circumferentially on the outer surface of the insertion portion and locking to the container side locking portion, and is removably attached to the container body to close the upper end opening, wherein one of the locking portions of the container side locking portion and the lid side locking portion is formed with a convex cross section, and the other locking portion is formed with a concave cross section, and the insertion portion of the lid body is positioned inside the outer periphery of the top plate.
[0009] A second aspect of the present invention is a wet tissue storage container of the first aspect, wherein the container body has a reinforcing thick portion that is provided on the inner surface below the container side engaging portion and extends around the entire circumferential area, protruding inward.
[0010] A third aspect of the present invention is a wet tissue storage container of the second aspect, wherein the reinforcing thick portion of the container body has a support upper surface that supports the insertion portion of the lid body from below, and an inclined surface that slopes downward and outward from the inner end of the support upper surface.
[0011] A fourth aspect of the present invention is a wet tissue storage container according to any one of the first to third aspects, wherein the lid body has a small lid that is supported on the top plate so as to be tiltable around a hinge axis and that covers the outlet so as to be able to be opened and closed, and the axial direction of the hinge axis of the small lid is parallel to one of the four sides of the top plate.
[0012] A fifth aspect of the present invention is a wet tissue storage container according to any one of the first to third aspects, wherein the rectangular cross section of the container body has four straight line portions that form the four sides and four curved line portions that form the four corners, and the ratio of the total length of the four straight line portions to the length of the entire circumference of the upper end opening of the container body is 30% or more and 85% or less.
[0013] A sixth aspect of the present invention is a wet tissue storage body comprising a wet tissue storage container according to any one of the first to third aspects and a roll of wet tissues stored in the wet tissue storage container, wherein the fitting strength between the lid body and the container body is 10 N or more and 60 N or less, and the removal resistance value when removing the wet tissues from the removal opening of the lid body is 1.5 N or more and 6.0 N or less. [Effects of the Invention]
[0014] According to the present disclosure, it is possible to provide a wet tissue storage container and a wet tissue storage body that improve the ease of opening and closing the lid body, and that are both compact and aesthetically pleasing. [Brief explanation of the drawings]

FIG. 6 is an enlarged view of part VI in FIG. 5(a). FIG. 7 is an explanatory diagram of a method for measuring fitting strength. FIG. 8 is an explanatory diagram of the compactness of a wet tissue storage container and a wet tissue storage body. Note that the stopper is not shown in FIG. 5. Also, FIG. 7 shows each component schematically.
[0018] <Wet tissue storage unit> As shown in FIGS. 1 and 2, the wet tissue storage body 100 according to this embodiment includes a wet tissue storage container 10 and a roll 1R of wet tissues 1 stored in the wet tissue storage container 10.
[0019] The roll body 1R of the wet tissue 1 has easy-to-tear sections (e.g., perforations) formed at predetermined intervals along the longitudinal direction, and the base fabric such as paper or nonwoven fabric is pre-impregnated with a chemical solution containing lotion, alcohol components, disinfectants, preservatives, etc.
[0020] <Wet tissue storage container> 1 to 6, the wet tissue storage container 10 according to this embodiment includes a container body 20 that stores a roll 1R of wet tissues 1, and a lid body 30 that is removably attached to the opening of the container body 20. The container body 20 and the lid body 30 fit together and are attached to each other by engagement between a container-side locking portion 24 and a lid-side locking portion 35, which will be described later.
[0021] <Container body> 1 to 3, 5, and 6, the container body 20 is formed in the shape of a cylinder with a rectangular cross section and a bottom, with a rectangular upper end opening 20a formed at the upper end, and defines a storage space 21 inside that can store the roll 1R of wet tissues 1. The container body 20 is formed by blow molding, injection molding, or the like (injection molding in this embodiment) using a thermoplastic resin such as polypropylene, polyethylene, polyvinyl chloride, or ABS resin.
[0022] The container body 20 has a rectangular bottom plate 22 and rectangular cylindrical side plates 23 that extend from the outer peripheral edge of the bottom plate 22 to the upper end opening 20a. The rectangular cylindrical side plates 23 are formed so that their cross-sectional shape expands from bottom to top. In other words, the container body 20 becomes thinner from top to bottom. The thickness of the rectangular cylindrical side plates 23 (excluding the container-side locking portions 24, the region above the container-side locking portions 24, and the reinforcing thick portions 26, which will be described later) is set to a substantially constant thickness. The outer peripheral surfaces of the rectangular cylindrical side plates 23 are formed linearly from bottom to top in a cross section along the vertical direction.
[0023] (Container side locking part) As shown in FIG. 6, the container body 20 has a container-side locking portion (the other locking portion) 24 that can be locked to a lid-side locking portion 35 (described later) provided on the lid 30. The container-side locking portion 24 is formed in the circumferential direction on the inner peripheral surface of the upper end portion of the container body 20. In this embodiment, the container-side locking portion 24 is formed with a cross-sectional concave shape that is recessed outward, and is formed in an annular shape that extends around the entire periphery of the inner peripheral surface of the upper end portion of the container body 20. The cross-sectional shape of the container-side locking portion 24 in this embodiment is formed in a semicircular shape.
[0024] (slope area) As shown in Figure 6, an inclined region 25 that slopes upward and outward is provided on the inner circumferential surface of the container body 20 above the container-side locking portion 24. The inclined region 25 is inclined at a larger angle relative to the vertical direction than the inner circumferential surface of the container body 20 excluding the container-side locking portion 24 and a reinforcing thick portion 26 (described later). The cross-sectional shape of the inclined region 25 widens from the container-side locking portion 24 toward the upper end opening 20a (see Figure 5). This makes it easier to insert the lid 30 (insertion portion 34 (described later)) into the container body 20 from the upper end opening 20a and to release the engagement between the container body 20 and the lid 30.
[0025] Furthermore, the thickness of the portion of container body 20 having inclined region 25 on the inside is preferably formed to become thinner from container-side locking portion 24 toward upper end opening 20a (see FIG. 6). This allows for the outer peripheral surface of side plate 23 to be formed flat (linear in a cross section along the vertical direction) while providing inclined region 25 on the inside.
[0026] (reinforced thick section) As shown in FIG. 6, the container body 20 preferably has a reinforcing thick portion 26 on the inner peripheral surface below the container-side locking portion 24. The reinforcing thick portion 26 protrudes inward, making it thicker than the areas above and below it. The reinforcing thick portion 26 is formed in an annular shape, extending around the entire circumferential area while protruding inward. The reinforcing thick portion 26 suppresses deformation of the upper end portion of the container body 20. Note that in this embodiment, the reinforcing thick portion 26 is provided on the container body 20, but this is not limited thereto, and the reinforcing thick portion 26 may not be provided.
[0027] The reinforcing thick portion 26 preferably has a support upper surface 26a that supports the lid 30 (the insertion portion 34 described below) from below, and an inclined surface 26b that slopes downward and outward from the inner end of the support upper surface 26a in a cross-sectional view (a cross-sectional view along the vertical direction). The support upper surface 26a is located at the upper end of the reinforcing thick portion 26 and extends inward from the inner circumferential surface of the container body 20. When the container body 20 and the lid 30 are fitted together, the support upper surface 26a abuts against the lower end of the insertion portion 34 of the lid 30 from below, supporting the lid 30 from below. The inclined surface 26b continues from the inner end of the support upper surface 26a to the inner circumferential surface of the container body 20 below the reinforcing thick portion 26. This prevents the reinforcing thick portion 26 from getting caught during molding of the container body 20. In this embodiment, the supporting upper surface 26a of the reinforcing thick portion 26 is illustrated as a plane intersecting the vertical direction, but this is not limited to this, and it is sufficient that the supporting upper surface 26a abuts the lower end of the insertion portion 34 of the lid body 30 from below.
[0028] 3, the inner end of the reinforcing thick portion 26 is located outside the outer edge 22a of the bottom plate 22 of the container body 20 in the storage space 21 in a top view. This allows the diameter of the roll 1R of wet tissues 1 to be increased to a position where it contacts the outer edge 22a of the bottom plate 22 without being limited by the reinforcing thick portion 26.
[0029] (Cross-sectional shape of container body) As shown in FIG. 3 , the rectangular cross section of the container body 20 has four straight line portions 27 that define four sides and four curved line portions 28 that define four corners. The ratio C (C = B / A × 100(%)) of the total length B of the four straight line portions 27 (total length B) to the total circumferential length A (the circumferential length A of the upper end) of the upper end opening 20a of the container body 20 is preferably 30% or more and 85% or less. If the ratio C is less than 30%, the upper end opening 20a approaches a circular cross section, which narrows the gap between the roll 1R of wet tissues 1 and the upper end of the container body 20 when refilling the container body 20 with the roll 1R, making refilling difficult. Furthermore, because the container body 20 approaches a circular cross section, even partial disengagement between the container body 20 and the lid 30 tends to lead to continued disengagement on both sides in the circumferential direction, making the lid 30 more likely to come off unintentionally. On the other hand, if the percentage C is greater than 85%, the straight portion 27 becomes too long, making it difficult to remove the lid 30 from the container body 20. The lower limit of the range of the percentage C is more preferably 45% or more. The upper limit of the range of the percentage C is more preferably 75% or less.
[0030] <Lid> 1, 2, and 4 to 6, the lid body 30 has a lid main body 31 and a spout 32 attached to the lid main body 31, and is detachably attached to the container main body 20 to close the upper end opening 20a. The spout 32 is formed with an outlet 32a through which the wet tissue can be taken out.
[0031] (lid body) The lid body 31 has a top plate 33 and an insertion portion 34 that extends downward from the top plate 33 and is inserted into the container body 20 through the upper end opening 20a to fit into the container body 20. The top plate 33 has a rectangular outer shape when viewed from above. The insertion portion 34 has a rectangular cross-sectional shape (a rectangular cylindrical shape in this embodiment) in a direction intersecting the vertical direction. That is, the lid body 30 has a rectangular top plate 33 and the insertion portion 34 that has a rectangular cross-sectional shape that extends downward from the top plate 33 and is inserted into the container body 20 through the upper end opening 20a. The lid body 31 is molded by blow molding, injection molding, or the like (injection molding in this embodiment) using a thermoplastic resin such as polypropylene, polyethylene, polyvinyl chloride, or ABS resin. Note that in this embodiment, the shape of the insertion portion 34 is a cylindrical shape with a rectangular cross-section, but is not limited thereto. For example, it may be a columnar shape with a rectangular cross-section.
[0032] (insertion part) The insertion portion 34 of the lid body 31 is positioned inside the outer periphery of the top plate 33 (see FIG. 6). The insertion portion 34 is formed slightly smaller than the upper end opening 20a so that it can fit into the upper end of the container body 20. The plate thickness of the insertion portion 34 (the plate thickness of the portion excluding the lid-side locking portion 35 described below) is thinner than the plate thickness (portion of approximately constant thickness) of the side plate 23 of the container body 20. The area of the underside of the top plate 33 outside the insertion portion 34 is supported from below by the upper end surface of the container body 20 when the container body 20 and the lid body 30 are fitted together (see FIG. 6).
[0033] As shown in FIG. 6 , a lid-side locking portion (one of the locking portions) 35 that can be locked to the container-side locking portion 24 of the container body 20 is formed on the outer peripheral surface of the cylindrical insertion portion 34 of the lid body 31. The lid-side locking portion 35 is formed circumferentially on the outer peripheral surface of the cylindrical insertion portion 34. That is, the lid body 30 has the lid-side locking portion 35 that is formed circumferentially on the outer peripheral surface of the insertion portion 34 and can be locked to the container-side locking portion 24. In this embodiment, the lid-side locking portion 35 is formed with a convex cross-section that protrudes outward and is formed in an annular shape that extends around the entire outer peripheral surface of the insertion portion 34. In this embodiment, the lid-side locking portion 35 has a semicircular cross-sectional shape. The lid body 30 and the container body 20 are attached to each other by fitting the lid-side locking portion 35 of the lid body 31 into the container-side locking portion 24 of the container body 20. When the container body 20 and the lid body 30 are attached to each other, the side surface of the container body 20 (the outer peripheral surface of the side plate 23) and the outer peripheral surface of the top plate 33 of the lid body 30 are flush with each other.
[0034] In this embodiment, the container body 20 is provided with the concave container-side locking portion 24, and the lid body 30 is provided with the lid-side locking portion 35 with a convex cross-section, but this is not limited to this, and for example, the container body 20 may have the convex container-side locking portion 24 on its inner peripheral surface, and the lid body 30 may have the concave lid-side locking portion 35 on its outer peripheral surface of the insertion portion 34. In this case, the container-side locking portion 24 serves as one locking portion, and the lid-side locking portion 35 serves as the other locking portion.
[0035] As shown in Figures 1, 4, and 5, the top plate 33 of the lid main body 31 has a stepped surface portion 36 that is recessed downward and lower than the surrounding area. In this embodiment, the stepped surface portion 36 is located at the center of the top plate 33. A circular surrounding wall 37 is erected on the outer periphery of the stepped surface portion 36. A through hole 38 is formed in the stepped surface portion 36, and a spout 32 is disposed below the through hole 38. In addition, a small lid 39 that can open and close the stepped surface portion 36 is connected to the lid main body 31. In this embodiment, the stepped surface portion 36 is provided with an introduction hole 40 and an induction path 41 in addition to the through hole 38, but this is not limited to this, and the circular through hole 38 may be provided without providing the introduction hole 40 and the induction path 41.
[0036] (small lid) As shown in Figures 1 and 4, the small cover 39 is supported on the top plate 33 of the cover body 31 so as to be tiltable around a hinge shaft 39a extending in a predetermined direction. The axial direction (the above-mentioned predetermined direction) of the hinge shaft 39a is parallel to one of the four sides 33a to 33d of the top plate 33 (opposing sides 33a and 33c in this embodiment). The hinge shaft 39a is disposed near the parallel side (side 33a in this embodiment). In addition, a grip portion 42 is formed on the side of the small cover 39 opposite the hinge shaft 39a to be gripped when opening and closing.
[0037] The small lid 39 is formed with a fitting wall 43 that fits tightly with the surrounding wall 37 to keep the inside of the surrounding wall 37 airtight. By closing the small lid 39, the fitting wall 43 fits tightly with the surrounding wall 37, making the inside of the surrounding wall 37 airtight, thereby preventing the roll R of wet tissues 1 (see FIG. 2) contained in the container body 20 from drying out. That is, the lid body 30 has the small lid 39 that is supported on the top plate 33 so as to be tiltable about the hinge shaft 39a and that covers the dispensing opening 32a of the spout 32 so as to be able to open and close. The top plate 33 of the lid body 31 is provided with a recess 44 that makes it easier to grip the grip portion 42 of the small lid 39 when the small lid 39 is closed. The recess 44 is located outside the stepped surface portion 36 and extends to the outer edge of the lid body 31 (the edge on the side of side 33c).
[0038] (Finger rest) 1 and 4, the lid body 31 of this embodiment is provided with a finger hook 48 that can be hooked with fingers when removing the lid body 30 from the container body 20. The finger hook 48 is formed in a plate shape in the vertical direction, and protrudes outward along a diagonal line from one of the corners of the lid body 31, which is rectangular in top view.
[0039] (Through hole) The through hole 38 is a through hole formed at a position where the spout 32 is attached, and is arranged on the stepped surface portion 36, on the opposite side of the hinge axis 39a of the small lid 39 (side 33c side) from the center of the top plate 33. By arranging the center of the through hole 38 and the center of the top plate 33 at different positions in this way, a wide area can be secured on the top plate 33 on the opposite side of the through hole 38 (the hinge axis 39a side in this embodiment), and therefore a wide area can be secured in which the introduction hole 40, which will be described later, can be formed. Note that in this embodiment, the through hole 38 is circular, but this is not limited to this and various shapes can be applied.
[0040] As shown in FIG. 5 , a plug support wall 45 is formed around the through-hole 38 on the underside of the top plate 33 (the stepped-down surface portion 36 in this embodiment) of the lid body 31. The plug support wall 45 is a wall for supporting the plug 32, and is arranged in a generally annular shape around the through-hole 38 at a distance from the through-hole 38. The plug support wall 45 in this embodiment is formed in a C-shape, with the portion of the guide path 41 described below being open. A locking protrusion 46 for locking the plug 32 is formed along the circumferential direction on the lower end side of the inner circumferential surface of the plug support wall 45. Note that, although the plug support wall 45 is formed in a C-shape in this embodiment, it is not limited to this and may have any shape that can support the plug 32.
[0041] (Inlet hole) The introduction hole 40 is a hole through which the tip of the wet tissue 1 pulled out from the roll 1R passes before being inserted through the outlet 32a when the first sheet of wet tissue 1 is inserted through the outlet 32a of the spout 32 to make the wet tissue 1 ready to be pulled out (hereinafter referred to as "setting"). The introduction hole 40 is formed to a size that allows the tip of the wet tissue 1 to be easily inserted. The introduction hole 40 of this embodiment is located slightly away from the through hole 38 towards the hinge shaft 39a of the small lid 39.
[0042] (taxiway) The guide path 41 is formed to be narrower than the diameter of the through hole 38, and connects the through hole 38 to the introduction hole 40. In this embodiment, it extends in a direction perpendicular to the hinge axis 39a of the small lid 39. When the wet tissue 1 is set in the dispensing opening 32a, the guide path 41 allows the tip of the wet tissue 1 to move from the introduction hole 40 to the dispensing opening 32a side of the spout 32 of the through hole 38.
[0043] (Seal) The spout 32 is made of a flexible elastic material. The spout 32 has a central outlet 32a and a slit 32b (see FIG. 4 ) extending from the outlet 32a to the outer edge of the spout 32. The spout 32 is disposed inside the spout support wall 45 and attached to the lid body 31 so as to close the through-hole 38. The spout 32 is attached to the lid body 31 by engaging with the engaging protrusion 46 of the spout support wall 45, with the slit 32b communicating with the guide path 41 of the lid body 31. That is, the lid body 30 has the outlet 32a provided in the top plate 33 and through which the wet tissue 1 can be dispensed. Note that in this embodiment, the top view shape of the spout 32 is circular, but this is not limited thereto and various shapes can be applied. Also, in this embodiment, the spout 32 has a slit 32b, but the slit 32b need not be provided.
[0044] (Fitting strength between lid and container body) The fitting strength between the lid body 30 and the container body 20 is preferably 10 N or more and 60 N or less. If the fitting strength between the lid body 30 and the container body 20 is less than 10 N, there is a risk that the lid body 30 will unintentionally come off from the container body 20 when, for example, removing the wet tissues 1. On the other hand, if the fitting strength between the lid body 30 and the container body 20 is greater than 60 N, it will be difficult to remove the lid body 30 from the container body 20 when, for example, refilling the roll 1R of wet tissues 1. It is more preferable that the lower limit of the above range of the fitting strength between the lid body 30 and the container body 20 is 15 N or more. It is more preferable that the upper limit of the above range of the fitting strength between the lid body 30 and the container body 20 is 50 N or less.
[0045] The fitting strength between the lid 30 and the container body 20 is measured using a Tensilon tensile tester. As shown in FIG. 7 , when measuring the fitting strength between the lid 30 and the container body 20, first, a plate 200 made of metal, resin, or the like, to which a string 201 is attached is prepared. The plate 200 has a shape and size that allows it to abut against the inner upper surface of the top plate 33 of the lid 30. The plate 200 is, for example, disk-shaped, and has a high-strength string 201, such as wire or string, attached to the center of the upper side of the plate 200. Then, after threading the string 201 from the inside to the outside of the wet tissue dispensing opening 32a, the string 201 is attached to a chuck 202 at the top of the Tensilon tensile tester, and the container body 20 is fixed below the Tensilon tensile tester. Thereafter, the lid 30 was pulled upward as indicated by arrow 203 at a tensile speed of 300 mm / min using a Tensilon tensile tester, and the maximum point load when the lid 30 came off the container body 20 was measured as the fitting strength.
[0046] (Resistance to remove wet tissue) The removal resistance value when removing the wet tissues 1 from the removal opening 32a of the lid body 30 (hereinafter sometimes referred to as the "removal resistance value of the wet tissues 1") is preferably 1.5 N or more and 6.0 N or less. If the removal resistance value of the wet tissues 1 is less than 1.5 N, the wet tissues 1 may not be torn at the easily tearable portions (e.g., perforations, etc.), and excessive amounts of the wet tissues 1 may be pulled out. On the other hand, if the removal resistance value of the wet tissues 1 is greater than 6.0 N, there is a risk that the lid body 30 may unintentionally come off the container body 20 when removing the wet tissues 1. It is more preferable that the lower limit of the above range of the removal resistance value of the wet tissues 1 is 2.0 N or more. It is also more preferable that the upper limit of the above range of the removal resistance value of the wet tissues 1 is 5.0 N or less.
[0047] The removal resistance value of the wet tissue 1 can be measured using a tensile tester (STB-1225S, manufactured by A&D Co., Ltd.) in accordance with the tensile test method of JIS P 8113, under the standard conditions specified in JIS P 8111. When measuring the removal resistance value of the wet tissue 1, first, the wet tissue 1 is set so that it protrudes about 10 mm from the outlet 32a of the lid 30, and is pulled out by hand. Then, the next wet tissue 1 is set (pulled out) by hand so that it protrudes about 20 mm from the outlet 32a.
[0048] Next, the set wet tissue 1 is clamped in place by a gripper (75 mm wide) for 20 mm in the flow direction, and the lid 30 is manually held down to prevent the wet tissue storage container 10 from moving. The wet tissue 1 is then pulled at a pulling speed of 100 mm / min, and measurement data is collected. Data is acquired every 16.7 μm, and the data is averaged from a distance of 40 mm to 150 mm (measurement length 110 mm) after the start of measurement. However, if a tear-prone area, such as a perforation, is included between 40 mm and 150 mm after the start of measurement, the distance after the start of measurement can be shortened to, for example, 90 mm (measurement length 50 mm), as long as it does not include the tear-prone area. Measurements are performed five times for each sample, and the average value is taken as the removal resistance value (N) of the wet tissue 1. If the wet tissue 1 breaks midway or cannot be pulled out due to the wet tissue 1 being twisted inside the wet tissue storage container 10, this is removed from the measurement data.
[0049] In the wet tissue storage container 10 and wet tissue storage body 100 configured as described above, one of the container-side locking portion 24 and the lid-side locking portion 35 (lid-side locking portion 35 in this embodiment) is formed with a convex cross-section, and the other locking portion (container-side locking portion 24 in this embodiment) is formed with a concave cross-section, and the lid body 30 and the container body 20 are attached to each other by fitting together. Therefore, when removing the lid body 30 from the container body 20, if a predetermined amount of force is applied upward to the lid body 30 while holding the container body 20, the locked state between the lid-side locking portion 35 and the container-side locking portion 24 is released, and the lid body 30 can be removed from the container body 20. Furthermore, when attaching the lid body 30 to the container body 20, the insertion portion 34 of the lid body 30 is inserted downward from the upper end opening 20a of the container body 20, and the lid-side locking portion 35 moves downward along the inner circumferential surface of the container body 20. When it reaches the container-side locking portion 24, it is locked by the container-side locking portion 24, and the lid body 30 can be attached to the container body 20. In this way, the lid body 30 and the container body 20 are detachable from each other by fitting them together. Therefore, unlike when detachable attachment is achieved by threading a male thread portion and a female thread portion, the lid body 30 is not tightened too tightly, which takes a long time to open, or is tightened too tightly, causing the lid to spin freely, and the lid body 30 does not open easily. In this way, the ease of opening and closing the lid body 30 can be improved.
[0050] The wet tissue storage container 10 according to the present disclosure also includes a container body 20 formed with a rectangular cross section, and a lid 30 having a rectangular cross-sectional insertion portion 34 that is inserted into the container body 20 from the upper end opening 20a. If the container body has a circular cross section, when a portion of the container body in the circumferential direction comes off the lid, the lid easily comes off the container body continuously from that portion to both sides in the circumferential direction. In the wet tissue storage container 10 according to the present disclosure, the container body 20 has a rectangular cross section, so that the lid 30 is difficult to remove at the straight portion 27 of the container body 20, and the lid 30 is easy to remove at the curved line portion 28 of the container body 20. For example, with the straight line portion 27 of the container body 20, only a portion of the straight line portion 27 does not come off the lid 30, and the entire straight line portion 27 must be removed to remove the lid 30, making it difficult to remove the lid 30. On the other hand, when a portion of the curved line portion 28 of the container body 20 in the circumferential direction is removed from the lid body 30, the lid body 30 can be easily removed from the container body 20 continuously from that portion to both sides in the circumferential direction.
[0051] As shown in FIG. 8(a), the insertion portion 34 of the lid 30 is positioned inside the outer periphery of the top plate 33, so the side of the container body 20 (the outer periphery of the side plate 23) and the outer periphery of the top plate 33 of the lid 30 can be positioned flush with each other without any step. This improves the external appearance of the wet tissue storage container 10 and ensures aesthetic appeal. Furthermore, the lid 30 has the insertion portion 34 that is inserted into the container body 20 from the top opening 20a, which enhances the compactness of the wet tissue storage container 10. As a result, as shown in FIG. 8(a), the wet tissue storage container 10 can be both compact and elegant. For example, in a configuration in which the lid A covers the outside of the container body B as shown in FIG. 8(b), if the step between the side of the container body B and the side of the lid A is eliminated to ensure aesthetic appeal, the inner periphery defining the storage space C of the container body B will extend outward beyond the top opening Ba, making it difficult to ensure compactness. Furthermore, as shown in Figure 8(c), in a shape in which the lid A covers the outside of the container body B, if the inner surface that defines the storage space C of the container body B is extended downward without any steps from the upper end opening Ba to ensure compactness, a step will be created between the side of the container body B and the side of the lid A, making it difficult to ensure aesthetic appeal.
[0052] Therefore, according to this embodiment, it is possible to provide a wet tissue storage container 10 and a wet tissue storage body 100 that improves the ease of opening and closing the lid body 30 and that is both compact and aesthetically pleasing.
[0053] Furthermore, by providing a reinforcing thick portion 26 on the inner peripheral surface of the container body 20 below the container-side locking portion 24, it is possible to suppress deformation of the upper end portion of the container body 20. This makes it possible to suppress detachment of the lid body 30 due to deformation of the upper end portion of the container body 20, and therefore prevents the lid body 30 from coming off unintentionally.
[0054] Furthermore, the reinforcing thick portion 26 of the container body 20 has a support upper surface 26a that supports the insertion portion 34 of the lid 30 from below, and an inclined surface 26b that slopes downward and outward from the inner end of the support upper surface 26a. By providing the reinforcing thick portion 26 with the support upper surface 26a that supports the insertion portion 34 of the lid 30 from below, the reinforcing thick portion 26 can support the lid 30 while reinforcing the container body 20. Furthermore, by providing the reinforcing thick portion 26 with the inclined surface 26b that slopes downward and outward from the inner end of the support upper surface 26a, it is possible to prevent the reinforcing thick portion 26 from getting caught when the container body 20 is formed.
[0055] Furthermore, the axial direction of the hinge shaft 39a of the small lid 39 is parallel to one of the four sides 33a to 33d (opposing sides 33a and 33c in this embodiment) of the top plate 33. Therefore, when the small lid 39 is opened, a force is applied from the lid body 30 to the linear portion 27 of the container body 20. Therefore, when the small lid 39 is opened, it is possible to prevent the lid body 30 from unintentionally coming off from the container body 20.
[0056] Furthermore, the finger hook 48 of the lid body 31 protrudes outward from one of the corners of the lid body 31 along a diagonal line, so that when removing the lid body 30 from the container body 20, a finger can be hooked on the finger hook 48 and the lid body 30 can be removed from the curved line portion 28 of the container body 20. This makes it easy to remove the lid body 30 from the container body 20.
[0057] Although the present invention has been described above based on the above embodiment, the present invention is not limited to the content of the above embodiment, and can be modified as appropriate without departing from the scope of the present invention. In other words, all other embodiments, examples, operational techniques, etc. made by those skilled in the art based on this embodiment are naturally included in the scope of the present invention.
