  An embodiment in which a container with a lid according to the present invention is applied for accommodating wet tissue will be described in detail with reference to FIGS. However, the present invention is not limited to these embodiments, and these configurations can be replaced and combined as necessary. In addition, the stored article is not limited to wet tissue, and any stored article can be adopted as long as it is necessary to be taken out from the opening.

  The appearance of the container with a lid in the first embodiment intended for a wet tissue is shown in FIG. 1 with the open / close lid open, and its disassembled state is shown in FIG. 2 with the open / close lid closed, and its cross section. The structure is shown in FIG. The lidded container 10 according to the present embodiment includes a container body 11, an opening / closing lid 12, a lock means 13, a torsion coil spring 14, a covering portion 15, and a lock release lever 16, and the torsion coil spring 14 is excluded. All of them are made of resin moldings.

  The container body 11 includes an elliptical tray portion 17 on which wet tissue W, which is a stored article, is placed, and a cover portion 18 that is superimposed on the tray portion 17 so as to cover the wet tissue W placed on the tray portion 17. Have.

  In the tray portion 17, a rectangular recess 17 a for suppressing the displacement of the wet tissue W and a groove portion 17 b along the outer peripheral edge portion of the tray portion 17 are formed. Further, on the outer wall of the groove portion 17b, a projection portion 17c protruding toward the opposed inner wall is formed over the entire circumference of the groove portion 17b.

  At the lower end of the cover portion 18 having an elliptical dome shape corresponding to the tray portion 17, a fitting portion 18 a to be inserted into the groove portion 17 b of the tray portion 17, and the tray portion 17 projecting radially outward from the fitting portion 18 a. A locking projection 18b that can be locked to the protruding portion 17c is formed. In a state where the fitting portion 18 a of the cover portion 18 is inserted into the groove portion 17 b of the tray portion 17, the protrusion portion 17 c formed on the groove portion 17 b of the tray portion 17 is a locking protrusion formed on the fitting portion 18 a of the cover portion 18. Lock to 18b. As a result, the cover portion 18 is prevented from coming off from the tray portion 17 unless a relatively large external force is applied. That is, both the tray part 17 and the cover part 18 can be elastically deformed, and when it is necessary to remove the cover part 18 from the tray part 17 for supplying the wet tissue W, a relatively large force is applied. Thus, these engaged states can be released. Therefore, at both ends along the major axis direction of the tray portion 17 (left and right direction in FIG. 2), finger hook portions 17d for facilitating the operation for removing the tray portion 17 from the cover portion 18 are respectively provided. Projected.

  On the other hand, the upper end portion of the cover portion 18 accommodates a flat recess portion 18c on which an opening / closing lid 12 described later is covered, a lid connecting recess portion 18d for connecting the base end portion of the opening / closing lid 12, and an unlocking lever 16 described later. A lever receiving recess 18e is formed. The lid connecting recess 18d and the lever receiving recess 18e are arranged along the minor axis direction (left and right direction in FIG. 3) of the cover 18 with the recess 17a interposed therebetween. An opening 11a having a dumbbell shape for taking out the wet tissue W is formed in the flat recess 18c. A locking claw portion 13a of the locking means 13, which will be described later, protrudes upward at a boundary portion between the flat concave portion 18c and the lever receiving concave portion 18e.

  FIG. 4 shows a cross-sectional structure in a state where the open / close lid 12 is opened, and FIG. 5 shows an enlarged view of the V-part of the arrow, and FIG. 6 shows an appearance of the torsion coil spring 14. The opening / closing lid 12 in the present embodiment that can open and close the opening 11a of the container body 11 has an elliptical dome shape. The opening / closing lid 12 includes a lid main body 19 connected to the cover portion 18 of the container main body 11 and a substantially flat lid plate portion 20 that is integrally coupled to the lid main body 19 in an overlapped state.

  At the base end portion (the left end portion in FIG. 3) of the lid main body 19, a connecting portion 12a disposed in the lid connecting concave portion 18d of the cover portion 18 is projected, and on both left and right side surfaces of the connecting portion 12a, A pair of pins 21a extending in a straight line are projected in opposite directions. Corresponding to the pair of pins 21a, a pair of pin holes 21b for pivotally supporting the pair of pins 21a is formed on the left and right side walls of the lid connecting recess 18d of the cover portion 18. The connection between the cover portion 18 and the open / close lid 12, that is, the fitting of the pin 21 a into the pin hole 21 b is performed by a press-fitting operation using elastic deformation of the resin material itself constituting the cover portion 18 and the lid body 19. The pair of pins 21 a and pin holes 21 b function as the hinge 21 of the present invention, and the opening / closing lid 12 is attached to the container body 11 via the hinge 21. A plurality of locking projections 19 a for fitting and holding the lid plate portion 20 are formed on the inner edge of the lid body 19 at a predetermined interval. Further, the inner end portion of the lid body 19 opposite to the connecting portion 12a has a locking recess 13b that can be locked by the locking claw portion 13a of the locking means 13 formed in the cover portion 18. A portion 13c is formed. That is, the locking portion 13c of the lid main body 19 and the locking claw portion 13a of the cover portion 18 function as the locking means 13 in the present invention, and these engage with each other, so that the spring force by the torsion coil spring 14 described later is applied. The opening / closing lid 12 is held in a closed state. At least one of the locking recess 13b and the locking claw 13a can be elastically deformed, and can be engaged and disengaged by applying an appropriate external force.

  The lid plate portion 20 to which the torsion coil spring 14 is attached has a plurality of projection receivers 20a corresponding to the locking projections 19a of the lid body 19 formed at predetermined intervals on the outer peripheral edge thereof. The locking projections 19a of the lid main body 19 are engaged with these projection receivers 20a in a press-fitted state, so that the lid main body 19 and the lid plate portion 20 are integrated. Further, the lid plate portion 20 avoids interference with the locking claw portion 13a so that the locking claw portion 13a of the cover portion 18 can be engaged with the locking recess portion 13b of the locking portion 13c of the lid body 19. An escape portion 20b is formed. A covering portion 15 disposed on the connecting portion 12a of the lid main body 19 is formed at the end opposite to the escape portion 20b, and the gap 22 formed inside the covering portion 15 is used as a spring member in the present invention. The torsion coil spring 14 is accommodated and held. One end side of the torsion coil spring 14 made of a metal spring wire is fixed in the covering portion 15, and the other end side protrudes outside from a slit-like relief portion 15 a formed in the covering portion 15. . However, the other end side of the torsion coil spring 14 exposed to the outside from the escape portion 15a is halfway along the axis of the torsion coil spring 14 so that the other end is accommodated in the gap 22 of the covering portion 15 (in FIG. Is folded in a loop around an axis parallel to the vertical direction. That is, both ends of the torsion coil spring 14 are covered with the outside by the covering portion 15, but in this embodiment, the other end of the torsion coil spring 14 is connected to the inside of the coil portion of the torsion coil spring 14. It is further bent to be located at Further, by arranging the other end portion of the torsion coil spring 14 including the loop-shaped folded portion 14a in a plane perpendicular to the rotation axis of the hinge 21, the width of the escape portion 15a can be minimized. The loop-shaped folded portion 14 a presses against the spring receiving inclined surface 23 formed in the lid connecting recess 18 d of the cover portion 18 and constantly urges a spring force that opens the opening / closing lid 12. The escape portion 15 a is for avoiding interference of the covering portion 15 accompanying the opening / closing operation of the opening / closing lid 12 with respect to the folded portion 14 a of the torsion coil spring 14. The relative position of the folded portion 14a with respect to can be changed.

  In the present embodiment, the folded portion 14a of the torsion coil spring 14 is formed by bending in the same direction as the coil winding direction, but the folded portion 14a can also be formed by bending in the opposite direction. The external appearance of another embodiment of such a torsion coil spring 14 is shown in FIG. 7, but the same reference numerals are given to parts having the same function. In addition, the folded portion 14a can be formed so as to be parallel to the spring receiving inclined surface 23. In any case, the other end of the torsion coil spring 14 must be accommodated in the covering portion 15. Don't be.

  In this way, the end of the torsion coil spring 14 is not exposed to the outside, and the looped folded portion 14a only protrudes from the escape portion 15a, so that the end of the torsion coil spring 14 is caught. There is no problem at all. For this reason, the open / close lid 12 can be easily and safely attached to the lid connecting recess 18 d of the cover portion 18.

  In addition, the coating | coated part 15 in this embodiment has the protection part 15c which can be return | folded by the self hinge 15b. When the torsion coil spring 14 is assembled to the cover plate portion 20, after the torsion coil spring 14 is attached to the cover portion 15, the protective portion 15c is folded back and the tip portion thereof is fused to the cover plate portion 20 by ultrasonic welding or the like. I am doing so. Thereby, the part of the torsion coil spring 14 other than the loop-shaped folded portion 14a can be made invisible from the outside.

  The unlocking lever 16 as the unlocking means of the present invention for releasing the closed state of the opening / closing lid 12 by the locking means 13 is disposed in the lever receiving recess 18 e of the cover portion 18. A pair of pins 16a extending in a straight line project from the left and right side surfaces of the lock release lever 16 in opposite directions. Corresponding to the pair of pins 16a, a pair of pin holes 18f for pivotally supporting the pair of pins 16a is formed in the left and right side walls of the lever receiving recess 18e of the cover portion 18. The connection between the cover portion 18 and the lock release lever 16, that is, the fitting of the pin 16a into the pin hole 18f, is performed by a press-fitting operation using elastic deformation of the resin material itself constituting the cover portion 18 and the lock release lever 16. . As a result, the lock release lever 16 is pivotally supported with respect to the cover 18 around the pair of pins 16a so as to be rotatable between the lock holding position shown in FIG. 2 and the lock release position shown in FIG. It is in a state.

  In the closed state of the open / close lid 12, the distal end portion of the lock release lever 16 is lifted from the lever receiving recess 18 e, whereas the base end portion is locked and held close to the distal end portion of the lid plate portion 20 of the open / close lid 12. In position (see FIG. 3). When the distal end portion of the lock release lever 16 is pushed down to the unlock position from this state, the proximal end portion of the lock release lever 16 pushes up the distal end portion of the opening / closing lid 12, thereby releasing the lock state of the lock means 13. That is, the engagement of the locking portion 13c of the lid body 19 with respect to the locking claw portion 13a of the cover portion 18 is released. As a result, the opening / closing lid 12 is opened as shown in FIG. 5 by the spring force of the torsion coil spring 14, and the wet tissue W can be pulled out from the opening 11a of the cover 18 (see FIG. 5). Even if a strong external force is applied to the opening / closing lid 12 and the opening / closing lid 12 is twisted and the opening / closing lid 12 is removed from the cover portion 18, the torsion coil spring 14 has only a looped folded portion. Only protrudes outward from the escape portion 15 a of the covering portion 15. For this reason, even if an excessive external force acts on the opening / closing lid 12 and the opening / closing lid 12 is removed from the cover portion 18, the covering state of both ends of the torsion coil spring 14 is maintained by the covering portion 15. As a result, the user does not inadvertently touch both ends of the torsion coil spring 14 and is extremely safe.

  On the contrary, when the opening / closing lid 12 is closed against the spring force of the torsion coil spring 14 and the engaging claw portion 13a of the cover portion 18 is engaged with the engaging portion 13c of the lid body 19, the tip of the unlocking lever 16 is engaged. The part also rotates from the unlocked position to the previous lock holding position. Thus, in this embodiment, the lock release lever 16 can be automatically rotated to the lock holding position in conjunction with the closing operation of the opening / closing lid 12. Therefore, the position of the pin 16a of the lock release lever 16 with respect to the position of the locking claw portion 13a of the cover 18 and the contact position of the base end portion of the lock release lever 16 with respect to the distal end portion of the opening / closing lid 12 at the lock holding position. Must be set appropriately.

  In the above-described embodiment, the embodiment in which the torsion coil spring 14 is incorporated in the opening / closing lid 12 has been described. However, a torsion spring can be used instead of the torsion coil spring 14. FIG. 8 shows the appearance of another embodiment of the container with a lid according to the present invention, FIG. 9 shows the appearance when the opening / closing lid is opened, and shows the appearance when the opening / closing lid and the torsion spring are disassembled. 10, the main part of FIG. 9 is extracted and enlarged and shown in FIG. 8 to 11, elements having the same functions as those of the previous embodiment are designated by the same reference numerals, and redundant description is omitted. This is almost the same as that described in Japanese Patent No. 104536.

  A frame 24 made of a resin frame is fitted into and integrally joined to a rectangular opening (not shown) formed on the upper end surface of the container body 11 made of paperboard. In the present embodiment, the region surrounded by the frame 24 forms the opening 11a in the present invention, and the resin opening / closing lid 12 is attached to the opening 11a so as to be freely opened and closed. A resin cover film 25 having a second opening 25a for taking out wet tissue (not shown) is integrally heat-sealed to the frame 24, and the cover film 25 is surrounded by the frame 24. It has become. One end in the longitudinal direction of a seal film 26 formed with an adhesive layer (not shown) that can be repeatedly peeled off from the cover film 25 is joined to the cover film 25. Therefore, the wet tissue can be taken out from the opening 25a by peeling the other end of the seal film 26 from the cover film 25 against the adhesive force of the adhesive layer. Further, by joining the seal film 26 to the cover film 25 again using the adhesive force of the adhesive layer, the opening 25a can be completely closed, and evaporation of volatile components contained in the wet tissue can be suppressed. As described above, in this embodiment, the double openings 11a and 25a are formed in order to take out the wet tissue. However, when there is no need to ensure high moisture retention in the container body 11, the cover film 25 or The seal film 26 may be omitted.

  A pair of pins 21a projecting from both left and right ends of the connecting portion 12a formed at the base end portion of the resin opening / closing lid 12 are fitted in a pin hole 21b formed at the rear end portion of the frame 24 in a press-fitted state. Are combined. These pins 21 a and pin holes 21 b constitute a hinge 21 that rotatably connects the opening / closing lid 12 to the frame 24. Further, a first connecting portion 27 a formed at the center in the longitudinal direction of the torsion spring 27 is inserted into the center of the connecting portion 12 a of the opening / closing lid 12, and a coupling portion 28 for housing the first connecting portion 27 is formed integrally with the opening / closing lid 12. Has been. The right and left ends of the coupling portion 28 are joined to the surface of the opening / closing lid 12, and the middle portion is a slit-like opening 28 a that holds the first connecting portion 27 a of the torsion spring 27 in a penetrating state.

  A similar pair of left and right covering portions 29 are formed integrally with the frame 24 on both the left and right sides of the rear end portion of the frame 24. The pair of left and right covering portions 29 are slit-like openings 29 a that respectively accommodate the second connecting portions 27 b formed at the left and right end portions of the torsion spring 27.

  The torsion spring 27 in the present embodiment includes a twisted portion 27c that extends in a straight line along the opposing direction of the pair of pin holes 21b, and a plurality of connecting portions 27a and 27b that extend at right angles to the twisted portion 27c. And have. In addition, the connecting portions 27a and 27b are provided at the opposite ends of the first connecting portion 27a formed at the center in the longitudinal direction of the twisted portion 27c, and opposite to the first connecting portion 27a. A pair of second connecting portions 27b formed. The first connecting portion 27 a is housed and held in the coupling portion 28 of the opening / closing lid 12 to connect the torsion spring 27 and the opening / closing lid 12, and the pair of second connecting portions 27 b is a pair of covering portions 29 formed on the frame 24. The torsion spring 27 and the frame 24 are connected to each other. In this case, both ends of the torsion spring 27 connected to the frame 24 are not visible from the outside by the pair of covering portions 29. Therefore, when the wet tissue is taken out from the opening 25a of the container main body 11, the both ends of the torsion spring 27 do not touch the person. The torsion spring 27 is defined in a bending direction of the spring wire constituting the torsion spring 27 so that the first and second connecting portions 27a, 27b and the torsion portion 27c are substantially on the same plane in the unloaded state. ing. Accordingly, in a state where the first and second connecting portions 27a and 27b of the torsion spring 27 are inserted into the coupling portion 28 and the covering portion 29, the torsion spring 27 gives a spring force to the opening / closing lid 12 so that the opening / closing lid 12 opens. .

  In the present embodiment, consideration is given so that the second connecting portion 27 b of the torsion spring 27 after being attached to the covering portion 29 does not come off from the covering portion 29. Specifically, the width dimension of the opening 29a is formed to be slightly smaller than the width dimension of the second connecting portion 27b, and the second connecting portion 27b after passing through it during mounting is returned to the original free state by the spring force. In this case, a step 29b that can be locked at its end is formed so as to face the opening 29a.
