Description

Auto-closing wet tissue cap with open-keeping function

[0001] The present disclosure relates to an automatic closing wet tissue cap having an open state maintenance function, and more particularly, to an automatic closing wet tissue cap having an open state maintenance function.

[0002] This application claims priority to Korean Patent Application No. 10-2023-0177149, filed December 7, 2023, the entire contents of which are incorporated herein by reference.

[0003] Generally, wet wipes are made by forming thin tissues from synthetic fibers, viscose fibers, cotton fibers, cellulose fibers, and natural plant fibers, adding water to them, and sterilizing them. They can be used to wipe the user's hands and face regardless of location, and recently, they are widely used to wipe the skin of infants and toddlers when changing diapers.

[0004] And, conventional wet tissues are sold stored in containers such as vinyl bags to prevent moisture evaporation and for easy portability. Conventional wet tissue containers are stored with a number of wet tissues folded inside, and are provided with a wet tissue body with a discharge port formed through which wet tissues are drawn, and an adhesive sheet attached to the upper surface of the wet tissue body to open and close the discharge port.

[0005] However, in the case of adhesive sheets, there is a problem that the adhesive strength weakens when repeatedly opened and closed, making it difficult to close the outlet properly, and because it is inconvenient to pull the sheet to open it each time, a product has been developed that has a wet tissue cap that is attached to the upper part of the wet tissue body and has a cover that opens and closes one side of the upper surface where the outlet is formed separately.

[0006] However, these conventional wet tissue cap products had a problem in that if the lid was folded to open the outlet and the lid was not closed again to close the outlet, foreign substances would enter through the outlet, contaminating the wet tissue, or moisture would escape through the outlet, causing the wet tissue to dry out.

[0007] Accordingly, Korean Patent No. 10-2459342 proposes an automatic closing cap for preventing wet tissue from drying out, which is configured to automatically close the cover by providing an elastic part to the wet tissue cap. However, in the case of the automatic closing cap for preventing wet tissue from drying out proposed in Korean Patent No. 10-2459342, the cover part must be continuously held when rotating the cover part to take out the wet tissue, so there is a problem of inconvenience in use when the wet tissue cap must be opened with only one hand, such as when holding a child.

[0008] The technical problem to be achieved by the present invention is to provide a wet tissue cap configured so that the cover of the wet tissue cap can be automatically closed using an elastic member, and when the cover is rotated by a preset angle or more, the open state of the wet tissue cap is maintained while the rotational state of the cover is maintained.

[0009] In addition, the purpose is to provide a wet tissue cap configured so that when the cover part is rotated below a preset angle, the cover part is rotated and closed by an elastic force acting on the cover part, thereby closing the wet tissue cap.

[0010] The purpose of the present invention is not limited thereto, and other purposes not mentioned will be clearly understood by those skilled in the art from the description below.

[0011] In order to achieve the above technical problem, one embodiment of the present invention is a wet tissue cap that is coupled to a wet tissue body and is provided to open and close a wet tissue outlet formed in the wet tissue body, the wet tissue cap comprising: a base portion coupled to the wet tissue body such that an opening is provided and the wet tissue outlet is arranged on the opening portion; a joint portion having one side connected to the base portion; a cover portion connected to the other side of the joint portion and provided to open or close the opening portion by rotating the joint portion about an axis; The present invention provides an automatic closing wet tissue cap having an open state maintenance function, which includes an elastic member which is fixed to the base part and the cover part, respectively, and is provided to provide an elastic force to the cover part in a direction approaching the base part when the cover part is rotated away from the base part, and when the angle between the base part and the cover part becomes greater than or equal to a preset angle due to the rotation of the cover part, the elastic member comes into contact with the joint part and the elastic member is supported by the joint part, and when the angle between the base part and the cover part becomes greater than or equal to a preset angle due to the rotation of the cover part and the elastic member comes into contact with the joint part, the rotational state of the cover part is maintained and the open state for the opening is maintained, and when the angle between the base part and the cover part becomes less than the preset angle due to the rotation of the cover part and the elastic member does not come into contact with the joint part, the cover part is provided to rotate toward the base part by an elastic force applied to the cover part to close the opening part.

[0012] In addition, the present invention provides an automatic closing wet tissue cap having an open state maintenance function, characterized in that the joint includes a folding portion, and the folding portion is formed along the longitudinal direction of the joint, but is formed with a thickness smaller than the thickness of each part of the joint.

[0013] In addition, the present invention provides an automatic closing wet tissue cap having an open state maintenance function, wherein the preset angle is an angle between 130° and 230°.

[0014] In addition, the present invention provides an automatic closing wet tissue cap having an open state maintenance function, wherein the joint includes a sealing wall, and the sealing wall is formed along the longitudinal direction of the joint, and is formed to stand up at a preset height on one side of the joint.

[0015] In addition, the present invention provides an automatic closing wet tissue cap having an open state maintenance function, characterized in that the elastic member includes a rubber material.

[0016] According to one embodiment of the present invention, a cover part of a wet tissue cap is configured to automatically close using an elastic member, and when the cover part is rotated by a preset angle or more, the open state of the wet tissue cap is maintained while the rotational state of the cover part is maintained, thereby eliminating the need to hold the cover part when pulling out a wet tissue from the wet tissue body, making it convenient to pull out a wet tissue.

[0017] In addition, when the cover part is rotated less than a preset angle while the wet tissue cap is open, the cover part is rotated and closed by an elastic force acting on the cover part, thereby making it possible to close the wet tissue cap with a simple operation.

[0018] The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description of the claims.

[0046] An automatic closing wet tissue cap (10) having an open state maintenance function according to one embodiment of the present invention is a member that is coupled to a wet tissue body (20) having a wet tissue provided therein as shown in FIG. 1, and is provided to open or close a wet tissue discharge port (21) formed in the wet tissue body (20).

[0047] An automatic closing wet tissue cap (10) having an open state maintenance function according to one embodiment of the present invention can be configured to include a base portion (100), a joint portion (200), a cover portion (300), and an elastic member (400), and is particularly characterized in that it includes an elastic member (400) fixed to each of the base portion (100) and the cover portion (300), such that the cover portion (300) rotates toward the base portion (100) by an elastic force provided by the elastic member (400) to cover the base portion (100).

[0048] Furthermore, when the cover part (300) is rotated so that the angle between the base part (100) and the cover part (300) becomes equal to or greater than a preset angle, the cover part (300) is configured to be in an open state relative to the base part (100) while the rotational state of the cover part (300) is maintained.

[0049] Hereinafter, with reference to FIGS. 1 to 14, each component of an automatic closing water tissue cap (10) having an open state maintenance function according to one embodiment of the present invention will be described in detail.

[0050] First, the base part (100) may be provided as a ring-shaped member having an opening (110) inside and formed in an overall rectangular shape, as an example, and the base part (100) may also be provided as a member made of a plastic material.

[0051] However, the base portion (100) may be formed in a circular or oval shape in addition to a square shape, and may also be formed in various shapes other than circular or oval.

[0052] The base part (100) can be coupled to the upper part of the wet tissue body (20) in which wet tissue is provided inside, and at this time, the base part (100) can be coupled to the upper part of the wet tissue body (20) so that the wet tissue discharge port (21) formed in the wet tissue body (20) is placed on the opening part (110).

[0053] At this time, the opening (110) of the base (100) can be formed in various shapes, and in one embodiment, the opening (110) can be formed in a size corresponding to the size of the wet tissue discharge port (21) formed in the wet tissue body (20), or can be formed larger than the size of the wet tissue discharge port (21).

[0054] Meanwhile, as shown in FIGS. 2 and 3, the base portion (100) may include a base side wall portion (130).

[0055] In more detail, the base side wall portion (130) can be formed to stand up at a preset height from one side of the base portion (100).

[0056] In addition, the base side wall portion (130) can be formed continuously along the outer perimeter of the base portion (100), and in one embodiment, when the base portion (100) is formed in a square shape, the base side wall portion (130) can also be formed in a square shape.

[0057] Of course, when the base portion (100) is formed in a circular or oval shape, the base side wall portion (130) can also be formed in a circular or oval shape.

[0058] That is, the base side wall portion (130) can be formed in various shapes corresponding to the shape of the base portion (100).

[0059] At this time, the thickness of the base side wall portion (130) may be formed to correspond to the gap between the outer wall (311) and the inner wall (313) formed in the cover portion (300) described later, or may be formed to be smaller than the gap between the outer wall (311) and the inner wall (313).

[0060] Here, the base side wall portion (130) is formed continuously along the outer perimeter of the base portion (100), but can be formed only in a portion of each portion of the outer perimeter of the base portion (100) excluding a portion where a joint portion (200) described later is formed.

[0061] Next, as shown in FIGS. 2 and 3, the base portion (100) may include a first fixing portion (150).

[0062] In more detail, as illustrated in FIG. 5, the first fixing member (150) may be formed in a portion adjacent to the joint (200) described later among each portion of the base portion (100), and may also be formed in a shape capable of fixing the elastic member (200) described later.

[0063] For example, the first fixing member (150) may be formed in a hook shape that can be used to fix an elastic member (400) provided in the form of an elastic band. In addition, the first fixing member (150) may be formed in various shapes, such as a ring shape or a protrusion shape.

[0064] Next, as shown in FIGS. 2 and 3, the base portion (100) may include a first locking portion (170).

[0065] In more detail, the first locking portion (170) may be formed on any part of the outer circumference of the base portion (100), and in one embodiment, the first locking portion (170) may be formed on the opposite part of the first fixing portion (150) described above.

[0066] As shown in each drawing, the first locking portion (170) may be formed in the form of a protrusion protruding from the outer surface of the base portion (100), but in addition, the first locking portion (170) may also be formed in the form of a recessed groove from the outer surface of the base portion (100).

[0067] The first locking part (170) may be provided to engage with the second locking part (350) provided on the cover part (300) described later, thereby fixing the cover part (300) to the base part (100), which will be described in detail below.

[0068] Next, the joint (200) is provided so that the base part (100) described above is connected to one side, as shown in FIGS. 2 and 3, and the cover part (300) described later is connected to the other side, thereby connecting the base part (100) and the cover part (300) to each other.

[0069] Here, the joint (200) may be formed integrally with the base (100) and the cover (300) by an injection molding method, or may be provided as a separate member from the base (100) and the cover (300) and may be provided so as to be coupled to the base (100) and the cover (300), respectively.

[0070] In more detail, as illustrated in FIG. 4, the joint (200) may include a bridge (210), a first region (230), and a second region (250).

[0071] First, the bridge (210) can be placed between the base portion (100) and the cover portion (300), and further, the bridge (210) can be provided with a member having variable or flexible properties so that the cover portion (300) can rotate with respect to the base portion (100).

[0072] Meanwhile, the joint (200) may include a fold (211) formed along the longitudinal direction of the joint (200) but having a thickness smaller than the thickness of each portion of the joint (200). In more detail, as illustrated in FIG. 5, the fold (211) may be provided on the bridge (210).

[0073] In one embodiment, the folding portion (211) may be formed along the length direction of the bridge (210), but may be formed with a thickness smaller than the thickness of each portion of the bridge (210).

[0074] In this way, by forming a folding part (211) on the bridge (210), the cover part (300) is provided so that the bridge (210) can be rotated in a manner of folding or unfolding based on the folding part (211).

[0075] As the bridge (210) is provided with a folding portion (211), when the cover portion (300) is folded and the opening portion (110) of the base portion (100) is placed in an open state, even if an elastic force due to the elastic member (400) is applied to the cover portion (300), it becomes easy to maintain the cover portion (300) in a folded state, which will be described in detail below.

[0076] Next, as illustrated in FIG. 4, the first region (230) of the joint (200) may refer to a region arranged between one widthwise side of the bridge (210) and the first fixing member (150) provided in the base portion (100), and the second region (250) may refer to a region arranged between the other widthwise side of the bridge (210) and the second fixing member (330) provided in the cover portion (300).

[0077] Meanwhile, the joint (200) may include a sealing wall (213) formed along the length direction of the joint (200) and standing up at a preset height on one side of the joint (200).

[0078] More specifically, as illustrated in FIG. 6, the bridge (210) may include a sealing wall (213).

[0079] In one embodiment, the sealing wall (213) is formed along the length of the bridge (210), but may be formed standing up at a preset height on one side of the bridge (210).

[0080] In one embodiment, the sealing wall (213) may be formed on at least one of the widthwise one side and the other side of the bridge (210), and at this time, the sealing wall (213) formed on one side of the bridge (210) may be formed to be connected to the base side wall (130) formed on the base part (100), and the sealing wall (213) formed on the other side of the bridge (210) may be formed to be connected to the outer wall (311) of the cover side wall (310) formed on the cover part (300) described later.

[0081] In this way, when the bridge (210) is provided with a sealing wall (213), when the cover part (300) is rotated to close the opening part (110) of the base part (100), the sealing wall (213) formed in the bridge (210) can block moisture from being discharged to the outside through the bridge (210), thereby improving the sealing property of the wet tissue cap (10).

[0082] Meanwhile, as illustrated in FIG. 6, a joint wall (251) can be formed in the second region (250).

[0083] In more detail, the joint wall (251) can be formed to stand at a preset height on the second area (250), and at this time, the joint wall (251) can be formed to be connected to the inner wall (313) formed on the cover part (300).

[0084] In this way, when the joint wall (251) is provided in the second region (250), when the cover part (300) is rotated to close the opening part (110) of the base part (100), the joint wall (251) formed in the second region (250) can block moisture from being discharged to the outside through the second region (250), thereby improving the sealing property of the wet tissue cap (10).

[0085] Meanwhile, in the case where the base side wall (130) provided in the base portion (100) is provided in a double-walled form like the cover portion (300), it goes without saying that a joint wall (not shown) can be provided in the first region (230) in the same manner as the second region (250).

[0086] As described above, the joint (200) may include a bridge (210), a first region (230), and a second region (250), and when the elastic member (400) described below is fixedly installed to the first fixing member (150) and the second fixing member (300), respectively, the elastic member (400) may be placed on the upper portions of the bridge (210), the first region (230), and the second region (250).

[0087] At this time, when a sealing wall (213) and a joint wall (251) are formed in the bridge (210), the first region (230), and the second region (250) of the joint (200), since interference may occur between the elastic member (400), the sealing wall (213), and the joint wall (251), the height of the sealing wall (213) and the joint wall (251) may be formed to be small.

[0088] Next, the cover part (300) may be provided as an example, as a whole, as a square plate-shaped member, and the cover part (300) may also be provided as a member made of a plastic material.

[0089] The cover part (300) is connected to the other side of the aforementioned joint part (200), and may be provided to open or close the opening (110) formed in the aforementioned base part (100) by rotating the joint part (200) about an axis, and accordingly, the cover part (300) may be formed in a shape and size corresponding to the base part (100).

[0090] That is, the cover part (300) can be formed in various shapes, such as a circular plate shape or an oval plate shape, corresponding to the shape of the base part (100).

[0091] Here, as shown in FIGS. 2 and 3, the cover portion (300) may include a cover side wall portion (310).

[0092] In more detail, the cover side wall portion (310) can be formed to stand up at a preset height from one side of the cover portion (300), and at this time, the cover side wall portion (310) can be formed at a height corresponding to the height of the base side wall portion (130) formed on the base portion (100).

[0093] In addition, the cover side wall portion (310) may be formed continuously along the outer perimeter of the cover portion (300), and in one embodiment, when the cover portion (300) is formed in a square shape corresponding to the base portion (100), the cover side wall portion (310) may also be formed in a square shape.

[0094] At this time, when the cover part (300) is formed in a circular plate shape or an oval plate shape corresponding to the base part (100), the cover side wall part (310) can also be formed in a circular or oval shape.

[0095] That is, the cover side wall portion (130) can be formed in various shapes to match the shape of the cover portion (300) that is formed in various ways corresponding to the base portion (100).

[0096] Here, as shown in FIGS. 3 and 5, the cover side wall portion (310) may include an outer wall (311) and an inner wall (313).

[0097] In more detail, the outer wall (311) and the inner wall (313) may be formed along the outer perimeter of the cover part (300), respectively, and at this time, the inner wall (313) may be formed on the inner side of the outer wall (311) at a certain distance from the outer wall (311).

[0098] Here, the outer wall (311) may be formed standing up along the outer perimeter of the cover part (300), but may be formed so as to be placed on the outer side of the base side wall part (130) formed on the base part (100) when the cover part (300) is rotated to cover the base part (100).

[0099] In addition, the inner wall (313) may be formed standing along the outer perimeter of the cover part (300) while being spaced apart from the outer wall (311) by a certain distance, and may be formed so as to be placed on the inner side of the base side wall part (130) formed on the base part (100) when the cover part (300) is rotated to cover the base part (100).

[0100] By forming it in this way, when the cover part (300) is rotated to cover the base part (100) as shown in FIG. 7, the base side wall part (130) formed on the base part (100) can be placed between the outer wall (311) and the inner wall (313) formed on the cover part (300).

[0101] In this way, by configuring the cover side wall portion (310) provided in the cover portion (300) as a double-wall structure including an outer wall (311) and an inner wall (313), and configuring the base side wall portion (130) formed in the base portion (100) to be inserted between the outer wall (311) and the inner wall (313), when the base portion (100) is covered with the cover portion (300) and the opening portion (110) is closed, moisture within the space surrounded by the base portion (100) and the cover portion (300) can be double-blocked from being discharged to the outside, thereby improving the sealing property of the wet tissue cap (10).

[0102] Meanwhile, the outer wall (311) is formed continuously along the outer perimeter of the cover part (300), but as shown in FIG. 5, it can be formed only in a portion of each portion of the cover part (300) excluding the portion where the aforementioned joint (200) is formed.

[0103] At this time, when a sealing wall (213) is provided on the other side of the bridge (210) of the joint (200) as described above, the sealing wall (213) formed on the other side of the bridge (210) can be formed to be connected to the outer wall (311) formed on the cover (300) as shown in FIG. 6.

[0104] Next, as shown in FIGS. 3 and 5, the cover side wall portion (310) may further include a closing wall (315).

[0105] In more detail, the closing wall (315) can be formed standing up at a preset height from one side, and at this time, the closing wall (315) can be formed between the aforementioned outer wall (311) and inner wall (313).

[0106] In one embodiment, the closing wall (315) may be formed between the outer wall (311) and the inner wall (313), and may be formed on one side adjacent to the longitudinal direction of the joint (200) bridge (210) and on the other side adjacent to the longitudinal direction of the joint (200), so as to close the space surrounded by the outer wall (311) and the inner wall (313).

[0107] In this way, since the cover part (300) is provided with a closing wall (315), when the base part (100) is covered with the cover part (300) to close the opening part (110), moisture within the space surrounded by the base part (100) and the cover part (300) can be prevented from being discharged to the outside through the space surrounded by the outer wall (311) and the inner wall (313), thereby improving the sealing property of the wet tissue cap (10).

[0108] Meanwhile, as illustrated in FIG. 6, when a sealing wall (213) is provided on the other side of the bridge (210) of the joint (200) and a joint wall (251) is formed in the second area (250) of the joint (200), the cover part (300) may be configured without including the sealing wall (315).

[0109] Meanwhile, as illustrated in FIGS. 8 and 9, the cover side wall (310) provided in the cover portion (300) includes an outer wall (311) and an inner wall (313), but the height of the inner wall (313) can be formed to be smaller than the height of the outer wall (311). At this time, the joint wall (251) formed on the second region (250) and connected to the inner wall (313) can also be formed to be as small as the height of the inner wall (313), so that interference with the elastic member (400) arranged on the second region (250) can be minimized.

[0110] Meanwhile, as shown in FIGS. 10 and 11, the cover side wall portion (310) provided in the cover portion (300) in another embodiment may be provided in a single-wall form in addition to the double-wall form including the outer wall (311) and the inner wall (313) as described above.

[0111] Here, in the case where the cover side wall portion (310) is provided in the form of a single wall, the cover side wall portion (310) may be formed to stand along the outer perimeter of the cover portion (300), but when the cover portion (300) is rotated to cover the base portion (100), it may be formed to be placed on the outer side of the base side wall portion (130) formed on the base portion (100).

[0112] That is, when the cover part (300) is rotated to cover the base part (100), the cover part (300) can be formed to cover the entire base part (100).

[0113] Next, as shown in FIGS. 2 and 3, the cover part (300) may include a second fixing part (330).

[0114] In more detail, as illustrated in FIG. 5, the second fixing member (330) may be formed in a portion adjacent to the aforementioned joint (200) among each portion of the cover member (300), and may also be formed in a shape capable of fixing the elastic member (200) described later.

[0115] As an example, the second fixing member (330) may be formed in a hook shape that can be used to fix an elastic member (400) provided in the form of an elastic band. In addition, the second fixing member (330) may be formed in various shapes, such as a ring shape or a protrusion shape.

[0116] Next, as shown in FIGS. 2 and 3, the cover portion (300) may include a second lock portion (350).

[0117] In more detail, the second locking portion (350) may be formed on any part of the inner circumference of the cover side wall portion (310) formed on the cover portion (300).

[0118] In one embodiment, the second locking portion (350) may be formed at any part of the inner circumference of the outer wall (311), and in particular, the second locking portion (350) may be formed at a position corresponding to the position at which the first locking portion (170) provided in the aforementioned base portion (100) is formed.

[0119] In addition, the second locking portion (350) may be formed in the form of a protrusion protruding from the inner surface of the outer wall (311), but in addition, the second locking portion (350) may also be formed in the form of a recessed groove from the inner surface of the outer wall (311).

[0120] In one embodiment, as shown in FIG. 7, when the first locking portion (170) is formed in the form of a protrusion protruding from the periphery of the base portion (100), the second locking portion (350) may be formed in the form of a protrusion protruding from the periphery of the inner surface of the outer wall (311), so that when the base portion (100) is covered with the cover portion (300), it may be provided to be caught and fixed by the first locking portion (170) in the form of a protrusion.

[0121] In addition, in another embodiment, the first locking portion (170) may be formed in a protruding shape around the base portion (100), and the second locking portion (350) may be formed in a recessed groove shape around the inner surface of the outer wall (311), so that when the base portion (100) is covered with the cover portion (300), the first locking portion (170) in the protruding shape may be inserted into and fixed in the second locking portion (350) in the groove shape.

[0122] In addition, as another embodiment, the first locking portion (170) may be formed in a recessed groove shape around the base portion (100), and the second locking portion (350) may be formed in a protrusion shape around the inner surface of the outer wall (311), so that when the base portion (100) is covered with the cover portion (300), the second locking portion (2450) in the protrusion shape may be inserted into and fixed to the first locking portion (170) in the groove shape.

[0123] As described above, the base part (100) is provided with a first locking part (170) and the cover part (300) is provided with a second locking part (350), so that the first locking part (170) and the second locking part (350) are interlocked and fixed, thereby fixing the base part (100) covered with the cover part (300).

[0124] Next, as shown in FIGS. 2 and 3, the cover portion (300) may include a handle portion (370).

[0125] In more detail, the handle portion (370) can be formed to extend to a preset length from the outer surface of the aforementioned cover side wall portion (310).

[0126] In addition, the handle portion (370) can be formed continuously along the outer perimeter of the cover portion (300), and in one embodiment, when the cover portion (300) is formed in a square shape, the handle portion (370) can also be formed in a square shape.

[0127] At this time, when the cover part (300) is formed in a circular plate shape or an oval plate shape corresponding to the base part (100), the handle part (370) can also be formed in a circular or oval shape.

[0128] That is, the handle portion (370) can be formed in various shapes to match the shape of the cover portion (300) that is formed in various ways corresponding to the base portion (100).

[0129] At this time, the handle part (370) can be formed to extend to a preset length from the outer surface of the outer wall (311) as shown in FIG. 7, and by providing the handle part (370) on the cover part (300) in this way, the user can rotate the cover part (300) more easily by placing a finger on the handle part (370).

[0130] Next, the elastic member (400) may be provided as a member including a rubber material as an example, and further, the elastic member (400) may be provided as a member in the form of a band having elasticity.

[0131] In one embodiment, the elastic member (400) may be provided as a member in the shape of a rubber band, but the elastic member (400) may be provided as a variety of members having elasticity, such as a spring, in addition to the rubber band-shaped member.

[0132] The elastic member (400) is fixed to the aforementioned base portion (100) and cover portion (300), respectively, and is provided to provide elastic force to the cover portion (300) in a direction toward the base portion (100) when the cover portion (300) is rotated away from the base portion (100).

[0133] In more detail, as illustrated in FIG. 5, the elastic member (400) can be fixed to the first fixing member (150) provided in the base portion (100) and the second fixing member (330) provided in the cover portion (330), respectively.

[0134] At this time, the elastic member (400) may be provided with various lengths and thicknesses in order to appropriately control the elastic force applied to the cover part (300) according to the positions of the first fixing part (150) provided in the base part (100) and the second fixing part (330) provided in the cover part (330).

[0135] Next, the automatic closing wet tissue cap (10) having an open state maintenance function according to one embodiment of the present invention is characterized in that, as shown in FIGS. 12 and 13, when the angle (A) between the base (100) and the cover (300) becomes greater than or equal to a preset angle due to the rotation of the cover (300), the elastic member (400) comes into contact with the joint (200) and the elastic member (400) is supported by the joint (200). At this time, when the angle (A) between the base (100) and the cover (300) becomes greater than or equal to a preset angle due to the rotation of the cover (300) and the elastic member (400) comes into contact with the joint (200), the open state of the opening (110) of the base (100) is maintained while the rotational state of the cover (300) is maintained.

[0136] To explain this in more detail, as described above, the elastic member (400) is provided to be fixed to the base part (100) and the cover part (300), respectively. In this case, when the elastic member (400) is provided as a flexible member such as an elastic band-shaped member, when the cover part (300) is rotated in one direction (clockwise in the drawing) so that the angle (A) between the base part (100) and the cover part (300) becomes a preset angle or more, the elastic member (400) can be configured to come into contact with the joint part (200) so that the elastic member (400) is supported by the joint part (200).

[0137] At this time, when the elastic member (400) comes into contact with the joint (200) and is supported by the elastic member (400), the shape of the elastic member (400) is deformed (the portion supported by the joint (200) is deformed convexly), and the rotational force that is generated by the elastic force that the elastic member (400) provides to the cover part (300) and acts in a one-way (counterclockwise direction in the drawing) direction on the cover part (300) is reduced, so that the cover part (300) does not rotate again toward the base part (100) and the rotational state of the cover part (300) can be maintained.

[0138] In addition, in a different way, when the elastic member (400) comes into contact with the joint (200) and is supported by the elastic member (400), the shape of the elastic member (400) is deformed (the portion supported by the joint (200) is deformed convexly), and the rotational force applied to the cover (300) due to the elastic force provided by the elastic member (400) to the cover (300) is converted to the opposite direction (clockwise in the drawing), so that the cover (300) does not rotate again toward the base (100) and the rotational state of the cover (300) can be maintained.

[0139] At this time, when the bridge (210) of the joint (200) is provided with a folding part (211) as described above, it becomes easier to maintain the rotational state of the cover part (300). When the angle (A) between the base part (100) and the cover part (300) becomes a preset angle or more due to the rotation of the cover part (300), the bridge (210) is folded convexly by the folding part (211), making it easier to maintain the folded state of the cover part (300).

[0140] Meanwhile, an automatic closing wet tissue cap (10) having an open state maintenance function according to an embodiment of the present invention is characterized in that, as shown in FIGS. 12 and 14, when the angle (A) between the base part (100) and the cover part (300) becomes less than a preset angle due to the rotation of the cover part (300) and the elastic member (400) does not contact the joint part (200), the cover part (300) is rotated toward the base part (100) by an elastic force acting on the cover part (300) to close the opening (110) of the base part (100).

[0141] As described above, when the elastic member (400) comes into contact with the joint (200) and is supported by the elastic member (400), the shape of the elastic member (400) is deformed, so that the rotational force acting on the cover part (300) becomes smaller, or the rotational force acting on the cover part (300) is switched in the opposite direction so that the cover part (300) does not rotate again toward the base part (100) and the rotational state of the cover part (300) can be maintained.

[0142] At this time, when the cover part (300) is rotated in the opposite direction (counterclockwise in the drawing) so that the angle (A) between the base part (100) and the cover part (300) becomes less than a preset angle, the elastic member (400) does not contact the joint part (200), so that the support by the joint part (200) is released, and accordingly, the shape of the elastic member (400) is gradually restored to a straight line, and the turning force acting on the cover part (300) in one direction (counterclockwise in the drawing) gradually increases, so that the cover part (300) can rotate toward the base part (100).

[0143] In addition, in a different way, when the cover part (300) is rotated in the opposite direction (counterclockwise in the drawing) so that the angle (A) between the base part (100) and the cover part (300) becomes less than a preset angle, the elastic member (400) does not come into contact with the joint part (200), so that the support by the joint part (200) is released, and accordingly, the shape of the elastic member (400) is gradually restored to a straight line, and the turning force acting on the cover part (300) is switched from the opposite direction (clockwise in the drawing) to one direction (counterclockwise in the drawing), so that the cover part (300) can rotate toward the base part (100).

[0144] Here, according to the above, the joint (200) may include a bridge (210), a first region (230) and a second region (250), and further, a sealing wall (213) may be provided on one side and the other side of the bridge (210), or a joint wall (251) may be provided on the first region (230) and the second region (250).

[0145] Accordingly, the elastic member (400) described above being supported by being in contact with the joint (200) may mean that the elastic member (200) is supported by being in contact with at least one of the bridge (210), the sealing wall (213), the first region (230), the second region (250), and the joint wall (251).

[0146] Meanwhile, the angle may be a preset angle between 130° and 230° so as to maintain the rotational state of the cover part (300) described above.

[0147] Meanwhile, as illustrated in Fig. 13, when the angle (A) between the base (100) and the cover (300) becomes greater than a preset angle due to the rotation of the cover (300), the outer surface of the cover (300) may be provided to be supported by the wet tissue body (20).

[0148] In this way, by configuring the cover part (300) to be supported by the wet tissue body (20), the cover part (300) is not excessively folded, so that even if the cover part (300) is pressed with a relatively small force while the cover part (300) is folded, the cover part (300) can rotate in the opposite direction (counterclockwise in the drawing) due to elasticity to close the opening (110).

[0149] Next, an automatic closing water tissue cap (10') having an open state maintenance function according to another embodiment of the present invention will be described with further reference to FIGS. 15 to 18.

[0150] A water tissue cap (10') according to another embodiment of the present invention has a difference in the configuration of the first locking part (170') provided in the base part (100) and the second locking part (350') provided in the cover part (300) compared to the water tissue cap (10) according to the above-described embodiment of the present invention.

[0151] Accordingly, the configuration of the first locking part (170') provided in the base part (100) and the second locking part (350') provided in the cover part (300) of the water tissue cap (10') according to another embodiment of the present invention will be described in detail below.

[0152] First, as shown in FIGS. 15 and 16, the first locking portion (170') may be formed on any part of the outer circumference of the base portion (100), and in one embodiment, the first locking portion (170') may be formed on the opposite part of the first fixing portion (150).

[0153] In more detail, as illustrated in FIG. 17, the first locking portion (170') may include an insertion portion (171') and a protrusion portion (173').

[0154] In one embodiment, the insertion portion (171') may be formed in a shape that penetrates the base side wall portion (130) in the thickness direction, and a flap (353') described later may be inserted into the insertion portion (171').

[0155] At this time, a protrusion (173') may be formed to protrude on at least one of the upper sides of the insertion portion (171'), and the protrusion (173') is provided to support the upper side of the flap (353') inserted into the insertion portion (171') and fix the flap (353') on the insertion portion (171').

[0156] Next, as shown in FIGS. 15 and 16, the second locking portion (350') is formed at any one portion of the outer circumference of the cover portion (300), and may be formed at a position corresponding to the position where the first locking portion (170') described above is formed.

[0157] More specifically, as illustrated in FIG. 17, the second locking portion (350') may include a pair of cutouts (351') and flaps (353').

[0158] In one embodiment, a pair of cuts (351') may be formed in a form that cuts a portion of the outer circumference of the cover part (300) toward the inside of the cover part (300).

[0159] As a pair of cut portions (351') are formed on the outer periphery of the cover portion (300), an outer wall (311) and an inner wall (313) are not formed between the pair of cut portions (351') in each part of the outer periphery of the cover portion (300).

[0160] Next, the flap (353') is formed to extend from the outer periphery of the cover part (300), and is provided so that both sides are separated from the outer periphery of the cover part (300) by a pair of cuts (351').

[0161] At this time, the flap (353') can be connected to the cover part (300) by the folding part (353-1'), and accordingly, the flap (353') can be provided to be folded toward the inside of the cover part (300).

[0162] By means of the first locking part (170') and the second locking part (350') described above, the cover part (300) can be rotated to cover the base part (100), and then the cover part (300) can be fixed to the base part (100).

[0163] In more detail, as illustrated in FIG. 18, when the base part (100) is covered with the cover part (300) and the flap (353') is pressed toward the insertion part (171'), the flap (353') is folded by the folding part (353-1') and passes through the protrusion (173') formed in the insertion part (171'), and after the flap (353') passes through the protrusion (173'), the outer surface of the flap (353') is supported and fixed by the protrusion (173').

[0164] The operation process of the water tissue cap (10) in one embodiment of the present invention described above is as follows.

[0165] First, when the cover part (300) covers the base part (100) and the wet tissue cap (10) is closed, the user can open the wet tissue cap (10) by gripping the cover part (300) and rotating it in one direction.

[0166] At this time, the cover part (300) can be easily rotated through the handle part (370) formed on the cover part (300).

[0167] Meanwhile, in the process of the user gripping the cover part (300) and rotating it in one direction, if the angle (A) between the base part (100) and the cover part (300) becomes greater than a preset angle and the elastic member (400) comes into contact with the joint part (200), the rotational state of the cover part (300) is maintained while the open state of the opening (110) of the base part (100) is maintained.

[0168] Thereafter, when the user wants to close the wet tissue cap (10), the user can press the cover part (300) to rotate the cover part (300) in the opposite direction of one direction, and when the angle (A) between the base part (100) and the cover part (300) becomes less than a preset angle and the elastic member (400) does not contact the joint part (200), the cover part (300) rotates toward the base part (100) by the elastic force acting on the cover part (300) to close the opening (110) of the base part (100).

[0169] In addition, after the cover part (300) rotates in the opposite direction by elastic force to cover the base part (100), the user can fix the cover part (300) to the base part (100) by pressing the second lock part (350) to engage the first lock part (170).

[0170] Although all components constituting the embodiments of the present invention have been described as being combined or operating in combination as one, the present invention is not necessarily limited to these embodiments. That is, within the scope of the present invention, all of the components may be selectively combined and operated in one or more combinations.

[0171] The above description is merely an illustrative illustration of the technical idea of ​​the present invention, and those skilled in the art will appreciate that various modifications and variations can be made without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the technical idea of ​​the present invention, and the scope of the technical idea of ​​the present invention is not limited by these embodiments. The scope of protection of the present invention should be interpreted by the following claims, and all technical ideas within a scope equivalent thereto should be interpreted as being included in the scope of the rights of the present invention.
