FIG. 3 is a view showing the upper surface of the wet tissue storage container according to the embodiment of the present invention with the small lid opened. FIG. 4 is an exploded perspective view showing the lower surface of the lid of the wet tissue storage container according to the embodiment of the present invention.

As shown in FIGS. 1 to 4, the wet tissue storage container S is composed of a container body 1 for storing a roll of wet tissue P and a lid 3 detachably attached to close an opening 2 of the container body 1. The roll body of the wet tissue P stored in the container body 1 is formed with easy-to-cut parts at predetermined intervals in the longitudinal direction, and the base fabric such as paper or nonwoven fabric is pre-impregnated with a chemical solution containing lotion, an alcohol component, a disinfectant, an antiseptic, etc.

The container body 1 has a bottomed cylindrical shape with an opening 2 at the upper end, and a male threaded portion 4 is formed on the outer peripheral surface of the upper end of the container body 1 along the circumferential direction. The container body 1 is molded by injection molding or the like using a thermoplastic resin such as polypropylene, polyethylene, polyvinyl chloride, and ABS resin.

The cover 3 has a top plate 5 and has a cylindrical shape with an open lower end, and includes a wet tissue insertion hole 6 drilled in the top plate 5, a plug 8 for closing the wet tissue insertion hole 6, a small lid 7 for freely opening and closing the wet tissue insertion hole 6, and a plug locking part 9 projecting from the lower surface of the top plate 5 and locking the plug 8. The lid body 3 is provided with a hinge portion 40 that pivotally supports the small lid 7 so that it can be opened and closed. The inner peripheral surface of the lower end of the lid body 3 is formed with a female threaded portion 10 along the circumferential direction to be screwed with the male threaded portion 4 of the container body 1 so as to be detachably fitted to the opening 2 of the container body 1.
The male threaded portion 4 has a height of 10 to 26 mm or less. The height of the male threaded portion 4, which is the height of the threaded portion of the container body, corresponds to the height absorbed by the lid 3, providing a compact structure.

The lid 3 is molded by injection molding or the like using a thermoplastic resin such as polypropylene, polyethylene, polyvinyl chloride, and ABS resin.
A top plate 5 of the lid body 3 is formed with a stepped surface portion 12 that is one step lower than the top surface portion 11 at the center of the top surface portion 11 . A circular surrounding wall 13 is erected on the stepped surface portion 12, and a circular wet tissue insertion hole 6 is bored in the center inside the surrounding wall 13. - 特許庁
The wet tissue insertion hole 6 is closed by a plug 8 , and the size of the wet tissue insertion hole 6 is such that a fingertip can be pushed into the wet tissue insertion hole 6 . Specifically, the diameter is preferably 10 to 20 mm, more preferably 12 to 18 mm, still more preferably 14 to 16 mm.
The mouth plug 8 is formed with a pull-out hole 17 for pulling out wet tissues.

A recessed area 14 lower in height than the surroundings is formed continuously with a stepped surface part 12 on the top plate 5 of the lid body 3, and the recessed area 14 is formed so as to continue to the outer peripheral wall of the lid body 3.例文帳に追加
A small lid 7 is connected to a portion on the opposite side of the recessed area 14 of the lid body 3, and the small lid 7 is formed with a double fitting wall 15 which is closely fitted to sandwich the surrounding wall 13 to keep the inside of the surrounding wall 13 in an airtight state. By closing the small lid 7, the fitting wall 15 is tightly fitted to the surrounding wall 13, and the inside of the surrounding wall 13 becomes airtight, so that the wet tissue P stored in the container body 1 can be prevented from drying.
The recessed region 14 has a sloped portion 14c that slopes downward in a region between the flat first region 14a and the flat second region 14b. The recessed region 14 can be formed continuously by all the slopes, but the structure of the lower surface of the lid 3 can be simplified by providing more flat regions.

As shown in FIG. 4, a convex region 18 is formed on the lower surface of the concave region 14 corresponding to the concave region 14, a first flat region 18a and a second flat region 18b are formed corresponding to the first flat region 14a and the second flat region 14b of the concave region 14, and an inclined portion 18c of the convex region 18 is formed corresponding to the inclined portion 14c of the concave region 14.
When the small lid 7 is closed by slanting the recessed area 14, the finger is caught on the end of the small lid 7 by putting the finger on the inclined part 14c of the recessed area 14, and the small lid 7 can be opened and closed smoothly.
The height difference between the first region 14a and the second region 14b of the depression is preferably 1 mm to 8 mm, more preferably 2 mm to 4 mm.

As shown in FIGS. 2 and 4, on the lower surface of the top plate 5, a plug locking portion 9 is provided so as to surround the wet tissue insertion hole 6 and protrude according to the shape of the leg portions 31, 32, 33, and 34 of the plug 8, and the leg portions 31 to 34 of the plug 8 are fitted and locked to the plug locking portion 9. Since the leg portions 31 to 34 of the plug 8 are made of an elastic material having flexibility as will be described later, they can be easily attached to and detached from the plug engaging portion 9 .

FIG. 5(a) is a front view of the plug of the wet tissue storage container according to the embodiment of the present invention, and FIG. 5(b) is a cross-sectional view of the plug. FIG. 6(a) is a front perspective view of the plug of the wet tissue storage container according to the embodiment of the present invention, and FIG. 6(b) is a rear perspective view of the plug. Description will be made with reference to FIGS. 5 and 6 and FIGS. 1 to 4 described above.

The plug 8 is made of a flexible elastic material, and the hardness of the plug 8 is preferably 70-100, more preferably 75-95, and even more preferably 80-90 in terms of durometer hardness.
As the material of the plug 8, for example, thermosetting elastomers (styrene, vinyl chloride, ester, olefin, amide, urethane) or thermosetting rubbers (silicone rubber, urethane rubber, fluororubber) can be used singly or as a composite material of two or more of these. In particular, styrene thermoplastic elastomers are desirable from the viewpoint of durability and chemical resistance.
The thickness of the spout 8 is preferably 3-6 mm.

The spout 8 has a cylindrical body portion 30 that closes the wet tissue insertion hole 6 and leg portions 31 to 34 extending outward from the body portion 30 .
The body portion 30 may have a shape that closes the wet tissue insertion hole 6 .
A draw-out hole 17 for drawing wet tissues is formed in the body part 30 .
The diameter of the body portion 30 is preferably 15 to 30 mm, more preferably 18 to 25 mm, still more preferably 20 to 23 mm, corresponding to the wet tissue insertion hole 6.

In the illustrated example, the legs 31 to 34 are formed to extend outward from the lower end of the body 30, but the legs 31 to 34 may be formed to extend outward from the middle position of the body 30.
The legs 31 and 32 are formed symmetrically with the body 30 as the center from the lower end of the body 30 . The legs 33 and 34 are vertically symmetrically formed with the body portion 30 as the center from the lower end of the body portion 30 . The leg parts 31, 32 and the leg parts 33, 34 are formed asymmetrically (deformed shape) horizontally and vertically around the body part 30 so that the plug 8 is installed in the correct direction.
The leg portion 31 is formed with tapered portions 31 a and 31 b extending outward from the body portion 30 . The leg portion 32 is formed with tapered portions 32 a and 32 b extending outward from the body portion 30 .

The plug locking portion 9 is formed to have a shape that fits at least a part of the contours of the leg portions 31 and 32 of the plug. For example, a part of the plug engaging portion 9 may be cut out.
As shown in FIG. 4, the plug engaging portion 9 has tapered portions 9a and 9b corresponding to the tapered portions 31a and 31b of the leg portion 31, and tapered portions 9c and 9d corresponding to the tapered portions 32a and 32b of the leg portion 32, respectively.

The drawer hole 17 has a central round hole 17a provided substantially in the center of the body, a slit hole 17b linearly formed around the central round hole 17a, and end round holes 17c provided at both ends of the slit hole 17b.
The diameter of the central round hole 17a and the hardness of the periphery are selected so that the first wet tissue can be passed through from the back side of the cover 3 with a finger and brought out to the front side.
Also, the size of the central round hole 17a is preferably such that the second sheet of the wet tissue is broken at the perforations and does not come out together.
The diameter of the central round hole 17a is preferably 1.0 to 5.0 mm, more preferably 1.5 to 4.0 mm, still more preferably 2.0 to 3.0 mm. The hardness around the central round hole 17a, the slit hole 17b, and the end round holes 17c of the plug 8 is preferably 70-100, more preferably 75-95, and even more preferably 80-90 in terms of durometer hardness. In the above range, when the wet tissue is pulled out, it can be correctly broken at the perforated position, preventing the second sheet from coming out together, and the second sheet is held with an appropriate length in the central round hole 17a. Furthermore, the first sheet of wet tissue can be easily passed through.
Also, by providing the end round holes 17c at both ends of the slit hole 17b, it is possible to prevent the end from avoiding when the first wet tissue is passed from the back side. Also, the resistance when pulling out the wet tissue becomes appropriate.
The length of the slit hole 17b (the connecting length from the center of the end round hole 17c to the center of the other end round hole 17c) is preferably 4.0 to 13.0 mm, more preferably 5.5 to 10.0 mm, and even more preferably 7.0 to 8.0 mm. The width of the slit (the length opposite to the length of the slit) is preferably 0.5 to 2.0 mm, more preferably 0.8 to 1.7 mm, still more preferably 1.1 to 1.4 mm. When it is in the above range, it is possible to obtain an appropriate take-out property while suppressing tearing of the edge when the first sheet of wet tissue is passed through.

As shown in FIGS. 1 and 3 to 6, the leg portions 31 and 32 of the plug are provided so that the slit hole 17b of the drawer hole 17 is positioned in the left-right direction when the small lid 7 is opened and viewed from the front. With this configuration, when the leg parts 31 and 32 of the plug 8 are fitted to the plug engaging part 9, the slit hole 17b of the drawer hole 17 can be positioned in the lateral direction (in the direction of the leg parts 31 and 32) when viewed from the front with the small lid 7 opened.
If the slit holes 17b are formed in the vertical direction when the wet tissue is taken out, the wet tissue will be biased downward, resulting in a reduced take-out resistance. On the other hand, by positioning the spout 8 so that the slit hole 17b is oriented in the left-right direction when the small lid 7 is opened and viewed from the front, the removal resistance can be made appropriate and the usability can be improved.

In the wet tissue storage container S configured in this way, the wet tissue P can be pulled out in the following manner. First, the lid 3 screwed to the container body 1 is rotated to be removed from the container body 1, and the small lid 7 of the lid 3 is opened to open the wet tissue insertion hole 6.例文帳に追加Next, the wet tissue P is inserted into the pull-out hole 17 of the plug 8 so that it can be pulled out. Thus, the work of inserting the wet tissue P into the pull-out hole 17 can be easily performed, and the wet tissue P can be easily pulled out.

Next, a large-capacity wet tissue storage container will be described.
FIG. 7 is a diagram showing the back side of the lid of the wet tissue storage container of this embodiment. FIG. 8 is a diagram showing a state in which the small lid of the lid body of the wet tissue storage container of this embodiment is closed. Description will be made with reference to FIGS. 7, 8 and, if necessary, FIGS.

As described above, the lid 3 is formed with the recessed region 14 lower in height than the periphery for opening the small lid 7 . This recessed region 14 is for inserting a fingertip to open the small lid 7. If the depth of the recessed region 14 is deep, it is easy to insert a fingertip and open the small lid 7. However, if the depth of the recessed region 14 is too deep, the part corresponding to the recess of the recessed region 14 protrudes from the lower surface of the top plate 5 of the lid 3, and the capacity of the container cannot be increased. Therefore, as shown in FIG. 7, a convex region 18 is formed on the lower surface of the lid 3 in the concave region 14 so as to correspond to the concave region 14, and the convex region 18 is formed so as not to protrude into the container from the height of the plug locking portion 9.
The female threaded portion 10 of the lid 3 is formed so as not to overlap the plug engaging portion 9 and the convex region 18 formed on the lower surface of the recessed region in the height direction.
When the depth of the recess is 5 to 10 mm, it is possible to increase the capacity of the container while maintaining ease of inserting a fingertip.

FIG. 9(a) is a diagram for explaining the size of a roll stored in a conventional wet tissue storage container, and FIG. 9(b) is a diagram for explaining the size of a roll stored in a wet tissue storage container according to an embodiment of the present invention.
As shown in FIG. 9A, the conventional wet tissue storage container 100 consists of a container body 101 with a height of 158 mm and a lid 103, and the height is increased due to the structure of the lid 103. Therefore, if the height of the container is restricted, the height of the container body 101 is also restricted, and the roll body R0 cannot be made into a wide roll body.
By improving the structure of the lid 3, compactness can be achieved by the following three methods.
(1) The thickness of the lid body 3 remains the same, the height of the container (the screw thread portion) is increased, and the height of the interior is increased. As a result, a large roll body can be accommodated without changing the height of the product.
(2) The height of the lid body 3 is made thin, and the height of the container (the portion other than the thread) is increased. As a result, a large roll body can be accommodated without changing the height of the product. However, in this case, if the lid body 3 becomes too thin, there is a problem that it is difficult to open and close.
(3) The height of the lid body 3 is reduced while the size of the roll remains unchanged. This makes it possible to make the product compact while maintaining the size of the contents.

For example, in the case of (3) above, in the case of the wet tissue storage container S, the protruding portion on the lower surface of the lid 3 is kept low, the thickness of the lid 3 is made thinner than before, and the position of the screw part of the lid 3 is devised, so that even if the entire height of the wet tissue storage container S is the same as the conventional one, the roll body R with the larger roll width than before can be stored in the container.
Here, by setting the position of the female screw portion 10 of the lid 3 as described above, the height of the lid 3 can be reduced, and the height of the lid 3 is, for example, preferably 15 mm or more and 40 mm or less, more preferably 20 to 35 mm, and even more preferably 25 to 30 mm.
The height of the roll body R is preferably 90 mm or more and 200 mm or less, more preferably 110 to 180 mm, still more preferably 120 to 150 mm.
The internal height X of the container composed of the container body 1 and the lid 3 is preferably 110 mm or more and 250 mm or less, more preferably 130 to 230 mm, still more preferably 140 to 200 mm.

Next, the opening angle of the small lid of the lid of the wet tissue storage container according to the embodiment of the present invention will be described.
FIG. 10(a) is an explanatory diagram of the opening angle of the small lid of the lid in the conventional wet tissue storage container, and FIG. 10(b) is an explanatory diagram of the opening angle of the small lid of the wet tissue storage container of the present invention.

As shown in FIG. 10(a), the opening angle of the small lid 107 of the lid 103 of the conventional wet tissue storage container 100 was approximately 90 to 110 degrees. If the opening angle of the small lid 107 is narrow, there is a problem that the small lid 107 becomes an obstacle when pulling out the sheet. Further, if the opening angle of the small lid 107 is narrow, there is a problem that the small lid 107 becomes an obstacle when the sheet is pulled out from the opposite side of the small lid 107 . Therefore, in the wet tissue storage container S of the present embodiment, the maximum opening angle of the small lid 7 of the lid body 3 is in the range of 120° or more and 180° or less so that the small lid does not get in the way when pulling out the sheet (FIG. 10B shows an example of 180°).
Although the details will be described later, by devising the structure of the hinge portion 40, the height X inside the container constituted by the container main body 1 and the lid 3 can be sufficiently secured.

Next, the structure of the hinge portion of the wet tissue storage container according to this embodiment will be described. FIG. 11 is a diagram illustrating the structure of the hinge portion of the wet tissue storage container of this embodiment. FIG. 12 is a view showing the rear side of the hinge portion of the lid of the wet tissue storage container of this embodiment.
The hinge part 40 is configured to keep the small lid 7 in a stationary state in an open state within a maximum opening angle range of 120° or more and 180° or less. In the example shown in FIG. 11, the small lid 7 is kept stationary with it opened at about 170 degrees.

The lid 3 has a base portion 25 provided outside the top plate 5 . The hinge portion 40 is formed on the base portion 25, and has first hinge portions 41 and 42, and a second hinge portion 43 located below the first hinge portions 41 and 42 and biasing the small lid 7 in the closing direction. By adjusting the amount of bending of the curved portion of the second hinge portion 43, the small lid 7 is biased in the closing direction.

The thin portions 41 a and 42 a that constitute the first hinge portions 41 and 42 are formed so as to be positioned outside the base portion 25 . Similarly, the thin portion 43 a that constitutes the second hinge portion 43 is also formed so as to be positioned outside the base portion 25 .
By forming the first hinge portions 41, 42 and the second hinge portion 43 on the base portion 25 and further forming the respective thin portions 41a, 42a and 43a so as to be located outside the base portion 25, the opening angle of the small lid 7 can be set to 120° or more and 180° or less, which is larger than the conventional one.

Abutting portions 41b and 42b are formed continuously from the thin portions 41a and 42a of the first hinge portions 41 and 42, and the abutting portions 41b and 42b abut the base portion 25 when the small lid 7 is closed. A contact portion 43b is formed obliquely continuously with the thin portion 43a of the second hinge portion 43. When the small lid 7 is closed, the contact portion 43b contacts the inclined portion formed in the recess 26 of the base portion 25.
By configuring as described above, the maximum opening angle of the small lid 7 of the lid body 3 can be in the range of 120° or more and 180° or less.

According to the present embodiment described above, the cover 3 can be made thinner by devising the shape of the plug 8 and the shape of the plug that is locked by the plug locking portion 9 .
In addition, according to this embodiment, the spout 8 is arranged so that the slit hole 17b is positioned in the left-right direction when viewed from the front with the small lid 7 opened. Therefore, the wet tissue is prevented from being biased toward the take-out hole 17 of the spout 8, and the take-out resistance becomes appropriate, thereby improving the usability.
According to this embodiment, the internal height of the container can be increased by devising the position of the screw portion. Specifically, in order to impart compactness, it is necessary to make the lid thin, and if the lid is thin, the cost can be reduced. On the other hand, if the lid is made too thin, there is a problem that it becomes difficult to open and close. Therefore, in order to impart compactness while maintaining a certain thickness of the lid, the screw part of the container body is raised and the lid absorbs the volume. With this configuration, it is possible to obtain a compact wet tissue storage container that is easy to open and close.
Further, according to the present embodiment, the thickness of the lid 3 can be reduced by devising the recessed region of the lid.
Further, according to the present embodiment, by devising the configuration of the hinge portion of the small lid of the lid, it is possible to make the lid 3 thinner and easier to use.

Although the present invention has been described above using the embodiments, it goes without saying that the technical scope of the present invention is not limited to the scope of the above embodiments, and it is obvious to those skilled in the art that various modifications or improvements can be made to the above embodiments. In addition, it is clear from the description of the scope of the claims that forms with such modifications or improvements can also be included in the technical scope of the present invention.
