Hereinafter, an example of a case where the opening and closing mechanism of the present invention is used in the wet tissue storage container 1 will be described with reference to the attached drawings.

As shown in FIGS. 1 and 2, the wet tissue storage container 1 includes a container body 11 and a lid 12, and the lid 12 is rotatably coupled to the container body 11 via a hinge portion 14. An elastic member 13 that elastically pushes the cover 12 in the opening direction is disposed in the vicinity of the hinge portion 14 between the container body 11 and the cover 12. The elastic member 13 of the illustrated example is a folded rubber sheet. The container body 11 includes a frame body 15 that forms a lower opening 3, and a sealing member 9 that covers a portion of the lower opening 3, Further, a take-out opening 4 for taking out the wet tissue 2, a seal pressing member 6 having an upper opening 5 having a larger opening than the take-out opening 4, and a bottom cover 16 fitted to the bottom of the frame 15 are formed. The wet tissue 2 is housed in a space formed between the frame 15 and the bottom cover 16. The material used for the manufacture of the wet tissue storage container 1 is exemplified by a thermoplastic resin, a metal, or a thermoplastic elastomer, and is not limited thereto. In addition, FIG. 2 is an illustration of the cover 12 in a state in which a part of the state is opened.

The hinge portion 14 includes: a rib 7 having a circular hole erected in the container body 11, and a pin 8 provided on the cover 12, by inserting the pin 8 of the cover 12 into the circular hole of the rib 7, the cover 12 is opposed The container body 11 is rotatably coupled. Therefore, the rotation axis of the cover 12 is a direction extending in parallel with the direction of the pin 8 of the hinge portion 14. In a direction orthogonal to the direction in which the rotation shaft of the cover 12 extends, a locking portion 21 that rotates together with the cover 12 is erected on the back side of the end portion of the cover 12 that is away from the hinge portion 14. The locking portion 21 is provided with a locking protrusion 23 that can enter a lock 40 to be described later. Further, the casing 15 included in the container body 11 is provided with a lock accommodating chamber 31 which is located away from the hinge portion 14 in a direction orthogonal to the direction in which the rotation axis of the cover 12 extends. Position.

Referring to Fig. 2, in the lock accommodating chamber 31 in which the lock member 40 is housed, an opening portion 32 is disposed, which is located at a position opposed to the lock portion 21 provided on the back side of the cover 12 when the cover 12 is closed. . The opening portion 32 is formed to allow the locking portion 21 to pass therethrough. The lock member 40 is slidably received in the lock housing chamber 31 in a direction orthogonal to the direction in which the locking projection 23 enters. Further, the lock accommodating chamber 31 is provided with an upper portion having an opening 32 The partition wall 33 and the bottom wall 34 opposed to the upper wall 33 further include a pair of first side wall portions 51 (see FIG. 4) that face each other in the sliding direction of the lock member 40, and a pair The second side wall portion 52 and the third side wall portion 53 that extend between the first side wall portions 51 are formed. The third side wall portion 53 is located between the hinge portion 14 and the second side wall portion 52. Further, between the second side wall portion 52 of the lock accommodating chamber 31 and the lock 40, a locking portion accommodating space 38 into which the locking portion 21 can enter and exit is formed. The locking portion accommodating space 38 is in communication with the opening portion 32.

Referring to Fig. 3, the locking portion 21 includes a pillar portion 22 that is erected on the lid 12, and a locking projection 23 that is positioned at the front end of the pillar portion 22 and protrudes in a direction substantially perpendicular to the pillar portion. The locking portion 21 is a member that is fixed to the cover 12. The shape of the locking projection 23 is not particularly limited. However, if it is formed in a cylindrical shape, the engagement and disengagement with respect to the lock 40 can be smoothly performed. The shape of the pillar portion 22 is also not particularly limited, and for example, a flat plate shape orthogonal to the protruding direction of the locking projection 23 can be formed. The locking portion 21 can be formed integrally or differently from the cover 12, and it is desirable to integrally form the cover 12 with a thermoplastic resin.

4 and 5, the lock member 40 slidably accommodated in the lock accommodating chamber 31 is a slightly L-shaped member having a base portion 48 and a body portion 49 extending orthogonally to the base portion 48. . When the base portion 48 is housed in the lock accommodating chamber 31, it can be slidably contacted at the bottom wall 34. Further, in the lock accommodating chamber 31, the base portion 48 extends from the surface 47 of the main body portion 49 toward the locking portion accommodating space 38 side. The main body portion 49 has a plate shape, and a locking portion 21 is formed on the surface 47 opposed to the locking portion accommodating space 38. The opening and closing portion 41 into which the locking projection 23 can enter and exit, the engaging portion 42 at which the locking projection 23 can be engaged, and the cam groove 43 that is returned from the inlet and outlet portion 41 to the inlet and outlet portion 41 via the engaging portion 42. A part of the cam groove 43 is curved in a direction parallel to the sliding direction of the lock member 40. When the lock 40 is viewed from the front, the engaging portion 42 is located at a position where the entry direction of the locking projection 23 is opposed to the entrance and exit portion 41. The size of the opening in the sliding direction of the lock member 40 of the door opening and closing portion 41 is gradually smaller as it is formed toward the cam groove 43. Further, at least a part of the entrance and exit portion 41 communicates with the opening 32 of the lock accommodating chamber 31. In addition, in FIGS. 4 to 6, the dot indicates that the inlet portion 41, the engaging portion 42, and the cam groove 43 are not disposed on the surface 47 of the lock member 40.

The sliding direction of the lock member 40 is a direction orthogonal to the entering direction of the locking projection 23, and in Fig. 4, the entering direction of the locking projection 23 is the longitudinal direction of the paper (indicated by a double-headed arrow Y), and the sliding of the lock member 40 The direction is the horizontal direction of the paper (indicated by the double-headed arrow X). In other words, the entering direction of the locking projection 23 is a direction substantially orthogonal to the direction in which the rotating shaft of the cover 12 extends, and the sliding direction of the lock member 40 is a direction parallel to the direction in which the rotating shaft of the cover 12 extends. However, the sliding direction of the lock member 40 is not limited thereto, and for example, the lock member 40 may be slid in a direction orthogonal or intersecting with respect to the direction of rotation of the cover 12 .

When the lock 40 is housed in the lock accommodating chamber 31, the lock is disposed away from the pair of first side wall portions 51 between the pair of first side wall portions 51. Thereby, the slidable range of the lock member 40 in the sliding direction of the lock member 40 is restricted.

As shown in FIGS. 2 and 4, both the upper wall 33 and the bottom wall 34 of the lock accommodating chamber 31 are provided with a slide restricting portion that restricts the sliding direction of the lock 40. Further, the lock member 40 has a follower portion slidably contactable with the slide restricting portion on the surface facing the upper wall 33 and the surface facing the bottom wall 34. Further, in the illustrated example, the upper wall 33 of the lock accommodating chamber 31 is formed as a different member from the container body 11, but the upper wall 33 may be integrally formed with the container body 11.

In the present embodiment, the slide restricting portion 37 disposed in the lock accommodating chamber 31 is a continuous ridge extending in a direction parallel to the sliding direction of the lock member 40, and is in the upper portion of the lock accommodating chamber 31. The wall 33 is provided with two continuous ridges, and one continuous ridge portion wider than the continuous ridge portion disposed on the upper wall 33 is disposed in the bottom wall 34. Further, the driven portion disposed in the lock 40 is a hemispherical follower portion 46. In the illustrated example, the driven portion 46 has a hemispherical shape, but may be formed in a columnar shape, a triangular pyramid shape, or a flat plate shape.

In the main body portion 49 of the lock member 40, on the surface facing the upper wall 33, the two follower portions 46 are disposed at intervals in a direction parallel to the sliding direction of the lock member 40, and are disposed in the lock member accommodating chamber. Between the two continuous ridges of the upper wall 33 of 31. In this way, by the follower portion 46 being located between the two continuous ridges, the lock member 40 can be smoothly slid in a predetermined direction, and further, the lock member 40 can be prevented from falling to the side of the lock portion accommodating space 38, or Reversing to the opposite side. Further, the lock member 40 is provided on the surface facing the lower bottom wall 34 of the lock accommodating chamber 31, that is, four follower portions 46 are provided on the inner side of the base portion 48, and are provided in the lock accommodating chamber 31. Bottom wall 34 Each of the two side faces of the one continuous ridge portion is disposed in slidably contact with the two driven portions 46. Thereby, the lock member 40 can be smoothly slid in a predetermined direction, and the lock member 40 can be prevented from being displaced from the sliding direction to be displaced. As apparent from the above description, the slide restricting portion has a function of preventing the lock member 40 from falling over or shifting in the lock housing chamber 31 in addition to the function of restricting the sliding direction of the lock member 40.

The specific form of the slide restricting portion 37 and the follower portion 46 is not limited to the illustrated example, and any function can be achieved by exhibiting the above-described functions. For example, one continuous ridge may be provided on both the upper wall 33 and the bottom wall 34, or two continuous ridges may be provided on both the upper wall 33 and the bottom wall 34. Further, the slide restricting means 36 is formed as a groove extending in at least one of the sliding directions of the lock member 40, and the follower portion may be formed as a projection such as a spherical shape or a plate shape which is slidable along the groove. The slide restricting portion and the driven portion are combined with a concave portion and a convex portion having a trapezoidal cross section. Further, as far as possible, the gap between the lock member 40 and the continuous ridge portion provided in the upper wall 33 of the lock accommodating chamber 31 is extremely small (for example, 0.5 mm or less), and when the lock member 40 is in the lock accommodating chamber 31. When the cover member 40 is to be overturned, the contact member 40 contacts the continuous ridge portion to prevent the lock member 40 from falling over in the lock member housing chamber 31.

Next, the inlet/outlet portion 41, the engaging portion 42, and the cam groove 43 disposed on the surface 47 of the lock 40 will be described with reference to Fig. 5 . The cam groove 43 is a groove for guiding the locking projection 23 of the locking portion 21 from the inlet and outlet portion 41 to the inlet and outlet portion 41 via the engaging portion 42 and having a groove depth of the groove along the locking projection 23 The part that gradually becomes shallower in direction; and the section where the depth of the groove suddenly becomes deeper. As mentioned above, card When the hinge portion 42 sees the surface 47 of the lock 40 from the front, it is disposed at a position where the entry direction of the locking projection 23 and the entrance and exit portion 41 face each other. Further, the locking projection 23 of the locking portion 21 moves along the cam groove 43 so as to be pressed toward the groove wall surface 44 of the cam groove 43. Here, the depth of the cam groove 43 is set so that the locking projection 23 is directed toward the cam groove 43 in consideration of the fact that the locking projection 23 is rotated around the rotation axis of the cover 12 through the cam groove 43. The groove wall surface 44 is pressed. For example, as shown in the example, when the locking projection 23 extends in a direction substantially orthogonal to the rotation axis of the cover 12, a fan-shaped rotational locus of the entire locking projection 23 is drawn around the rotation axis of the cover 12. At least the bottom surface of the engaging portion 42 and a portion of the groove wall surface 44 of the cam groove 43 adjacent to the engaging portion 42 may be included.

As shown in FIGS. 5(a) to 5(d), the cam groove 43 is divided into an entry groove portion 61 from the entrance/exit portion 41 to the engagement portion 42, and an exit groove portion 62 that returns from the engagement portion 42 to the entrance and exit portion 41. The entry into the groove portion 61 and the exit groove portion 62 merge at the inlet and outlet portion 41. At the junction of the entrance groove portion 61 and the exit groove portion 62, the entry groove portion 61 is formed deeper than the exit groove portion 62 (see FIGS. 5(c) and (d)). As described above, the step between the entrance groove portion 61 and the exit groove portion 62 that joins the inlet and outlet portion 41 has a step, and the locking projection 23 of the locking portion 21 that has entered from the inlet and outlet portion 41 is induced into the groove portion 61. As shown in FIG. 5(a), the groove portion 61 is divided into a first entry groove portion 61a that is branched from the entrance and exit portion 41, and a second entry groove portion that is positioned between the first entry groove portion 61a and the engagement portion 42. 61b. As shown in Fig. 5 (b), the depth of the first entrance groove portion 61a gradually becomes shallower toward the second entrance groove portion 61b, and becomes sharper in the second entrance groove portion 61b. First entry into the groove The boundary between the 61a and the second entrance groove portion 61b is a curved portion 64 that enters the groove portion 61. Further, the depth of the engaging portion 42 is formed deeper than the entry groove portion 61 (Figs. 5(b) and 5(c)). Therefore, the locking projection 23 does not return to the first inlet groove portion 61a from the second inlet groove portion 61b, and there is no possibility that the locking projection portion 42 returns to the second inlet groove portion 61b. The depth of the exit groove portion 62 is deeper than that formed by the engaging portion 42 (Fig. 5 (c), (d)), and the curved portion 65 passing through the exit groove portion 62 gradually becomes shallower toward the inlet and outlet portion 41. Therefore, the locking projection 23 that has entered the exit groove portion 62 does not return to the engaging portion 42.

The operation of the opening and closing mechanism of the present invention will be described with reference to Fig. 6 . Further, in order to facilitate the viewing of the drawing, the pillar portion 22 and the locking projection 23 are indicated by imaginary lines in FIGS. 6(a) to 6(f).

When the cover 12 for closing the cover 12 (not shown) is pressed, as shown in FIG. 6(a), the locking projection 23 of the locking portion 21 enters the entrance and exit portion 41 of the lock member 40, and further along the cam groove 43. The first and second entry grooves 61a and 61b move. At this time, the locking projection 23 is linearly moved as viewed from the front surface of the surface 47 of the lock member 40. Therefore, as shown in FIG. 6(b), the lock member 40 is in the extending direction of the continuous ridge portion which is a slide restricting portion, and is slid in the left direction of the drawing in the illustrated example. As shown in FIG. 6(c), when the locking projection 23 enters the curved portion 64 of the groove portion 61, the lock 40 is closest to one of the pair of first side wall portions 51. Further, the locking projection 23 is pressed against the groove wall surface 44 of the cam groove 43. Therefore, the locking projection 23 of the curved portion 64 falls into the second entrance groove portion 61b (not shown) having a depth deeper than the first entrance groove portion 61a. At this time, when the hand is released from the cover 12, due to the cover Since the elastic member 13 is ejected in the opening direction by the elastic member 13 (not shown), the locking projection 23 is moved in the direction of the entrance and exit portion 41 as shown in Fig. 6(d), and further from the second entrance groove portion 61b. It falls into the engaging portion 42 and is locked. Thereby, the cover 12 is closed. In order to open the cover 12, the elastic force against the elastic member 13 is pressed against the cover 12 by hand, as shown in Fig. 6(e), the locking projection 23 is dropped from the engaging portion 42 into the exit groove portion 62 to the exit groove portion 62. The part 65 moves. When the locking projection 23 reaches the curved portion 65 of the withdrawal groove portion 62, the lock 40 is closest to the other of the pair of first side wall portions 51. Thereafter, when the hand is released from the cover 12, the locking protrusion 23 is moved from the exit groove portion 62 to the entrance and exit portion 41 by the elastic force of the elastic member 13 which is pushed by the cover 12 in the opening direction (Fig. 6(f)). Further, it is detached from the lock 40 (not shown). Thereby, the lid 12 is opened.

When the cover 12 is opened, that is, after the locking projection 23 is detached from the lock member 40, the entrance and exit portion 41 of the lock member 40 is positioned at a position facing the locking projection 23. It is assumed that even when the wet tissue 2 is taken out from the container body 11, the position of the entrance and exit portion 41 is shifted from the position facing the locking projection 23, and the opening size in the sliding direction of the lock member 40 of the entrance and exit portion 41 can be used. As the cam groove 43 gradually becomes smaller and the sliding range of the lock 40 is restricted by the pair of first side wall portions 51, the locking projection 23 can surely enter the lock 40.

As described above, according to the present invention, there is provided an opening and closing mechanism which can open and close a lid with a single touch pressure. Here, even if the lock member 40 having the cam groove 43 is fixed in the lock accommodating chamber 31, the base end portion of the locking portion 21 is set to be rotatable or rotatable relative to the cover 12, and The opening and closing mechanism of the lid 12 is opened and closed by a single touch. However, when the base end portion of the locking portion 21 is swingable, the vicinity of the root portion of the locking portion 21 may be damaged. Further, when the base end portion of the locking portion 21 is set to be rotatable relative to the cover 12, it is necessary to provide a rotating mechanism on the cover 12, and the structure is complicated, and the cover 12 becomes heavy and does not easily open. In the present invention, the locking portion 21 is fixed to the cover 12, and by making a configuration in which the lock member 40 disposed on the container body 11 is slid, the locking portion 21 can be made to be shaken or rotatable, and the one-touch can be used. Press to open and close the lid 12. Thereby, it is possible to provide an opening and closing mechanism that can open and close the lid with a single structure and a high reliability with a simple structure. Further, the lock accommodating chamber 31 may be disposed in the cover 12. However, when such a lid 12 is used in the wet tissue storage container 1, the lock accommodating chamber 31 and the lock member 40 housed therein are easily printed in the eyelid when the lid 12 is opened. Therefore, when the state of the lid 12 is opened, there is a fear that the child accidentally touches the lock member 40, and the opening and closing mechanism cannot be normally operated. In the present invention, since the lock member 40 is housed in the lock accommodating chamber 31 disposed on the container body 11 side, the lock member 40 is not easily printed in the eyelid state even when the cover 12 is opened, and there is no possibility of a child accidentally touching. . Therefore, the opening and closing mechanism of the present invention is particularly suitable for use in the wet tissue storage container 1.

The embodiments of the present invention have been described above, but the present invention is not limited thereto, and various modifications can be made. For example, the shape of the lock accommodating chamber 31 is not limited to the rectangular parallelepiped of the illustrated example, and may be any shape such as a corner post having a trapezoidal cross-sectional shape. Further, a plurality of lock accommodation chambers 31 may be provided. The material for opening and closing the opening and closing mechanism of the opening and closing container of the present invention is not particularly limited, and may be from a thermoplastic resin, A well-known material such as a metal or a thermoplastic elastomer is arbitrarily selected. For example, a metallic spring can be used in the elastic member 13.
