Description

  The present invention relates to a container in which an outlet provided on the top side of a container body is closed with an openable lid.

  As a resin-made container for a bag-packed article in which a large number of wet tissues are folded and stored so that a predetermined number of sheets can be taken out one by one, it is disclosed in, for example, Japanese Patent Application Laid-Open No. 11-180460 (hereinafter referred to as Prior Document 1). Containers with lids are known. In the container of this publication, the bottom of the container main body is opened almost entirely, and the opening is closed with a bottom lid separable from the container main body, so that the wet tissue packed in the bag can be replaced. . A wet tissue outlet is formed on the top side of the container body, and the outlet is closed by an upper lid hinged to the container body. The container body is provided with an upper lid urging means for urging the upper lid in the opening direction and a holding portion for holding the upper lid in a closed position against the force of the upper lid urging means. When the user pushes in the holding portion, the holding portion and the upper lid are disengaged, and the upper lid is opened by the upper lid urging means. In other words, the upper lid is opened with a single push, which is convenient for the user.

  By the way, as shown in FIG. 32, for example, the container holding portion described in the prior art document 1 includes a claw portion 202 provided in the operation portion 201 integrated with the container body 200 and a claw portion 204 provided in the upper lid 203. The upper lid 203 is held by meshing in the vertical direction. When the user pushes the front end of the operation unit 201, the claw portion 202 on the main body side retracts from the upper lid 203, whereby the upper lid 203 is released and the upper lid 203 is opened.

  However, in the meshing structure between the claw parts 202 and 204 as described above, when some impact is applied to the container, the meshing between the claw parts 202 and 204 is easily released, and the upper lid 203 is opened by a spring force. If such a phenomenon occurs when a container main body incorporating an upper lid is placed on a production line and transported one by one, the transport posture of the container main body is not stable, leading to poor transport.

  Japanese Patent Application Laid-Open No. 9-58725 (hereinafter referred to as Prior Art Document 2) discloses that an opening operating member having a claw portion that meshes with a claw portion of an upper lid is hinge-coupled to a container body, and the operation member The container which urges | biases the operation member for opening | release in the direction which nail | claw parts mutually mesh | engage with the spring member provided in is disclosed. However, the claw portion of the container is the same as that shown in FIG. 32, and the meshing is easily disengaged. And the container of the prior art document 2 is provided with the flange which pushes up the nail | claw part of an upper cover in the operation member for opening. Accordingly, when the operation member rotates due to an impact when the container is dropped, a force for pushing up the upper lid is generated, and the force acts to disengage the claws, so that the upper lid may be more easily opened. Moreover, since the spring part of the opening operation member is provided in a cantilever state, there is anxiety about the strength of the spring part against repeated use.

  Japanese Patent Laid-Open No. 2000-211661 (hereinafter referred to as Prior Document 3) provides a claw portion for holding the upper lid in a closed state on the upper lid and the container main body, and the container main body has an opening operation. A container having a member attached via a hinge is disclosed. In this container, the pushing operation of the operating member is transmitted as an upward force to the upper lid, whereby the upper lid side claw portion gets over the container main body side claw portion and the upper lid is released from the restraint. The operating member is integrally formed with a spring member for holding it in a non-operating state, that is, in a state where the upper lid is not pushed up. However, the spring member does not press the claws together.

  It is an object of the present invention to provide a container with a lid that can reliably restrain a lid that covers a content outlet and prevents the lid from being unintentionally opened due to vibration or the like.

In addition, the present invention is intended to allow the lid to be inadvertently moved in the direction of disengaging the claw when the operating component operated to open the lid is rotatably attached to the container body. the object of the invention is to provide a lidded container is no risk of being released without.

  The present invention will be described below. In order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are appended in parentheses, but the present invention is not limited to the illustrated embodiment.

The container with a lid of the present invention includes a container body (2) having a content outlet (10) and a lid (4) connected to the container body via a hinge portion (44) and capable of closing the outlet. ), Lid urging means (5) disposed between the container body and the lid and urging the lid in a direction to open the lid, and rotating on the container body via a predetermined hinge (64) A freely mounted operation part (6) and a spring means (65) for urging the operation part are provided, and a pair of claw portions (43, 63) respectively provided on the lid and the operation part are provided. The claw portion can be restrained to a position where the lid is closed by meshing, the claw portion can be released by operation of the operation component, and the operation component is biased by the spring means in a direction in which the claw portion is engaged. In the lidded container (1), of the pair of claws, The tip of the other claw part (AP) while the contact part of the one claw part (43) with the other claw part (63) is in contact with the opposing surface (63a) of the other claw part. And the one claw part has a shape that extends to the back side beyond the tip of the other claw part, and the operation component is mounted in the recess (30) of the container body, When the operation component is operated beyond the position where the mesh is disengaged, the operation of the operation component is restricted by contacting the edge (30d) of the recess, and the operation of the operation component is limited by the edge of the recess. In the state where the tip protrudes from the outer surface of the container main body around the recess and the region (P) where the one claw and the other claw are engaged with each other, the shaft core (Ax ) that is spaced forwardly and downwardly It is an butterfly.

According to the container with a lid of the present invention, the claw portion can mesh in two directions. Therefore, even if an impact or vibration is applied to the container, the engagement of the claw portions becomes difficult to be released, and unintentional opening of the lid can be prevented. Since an operation component that can freely rotate is attached to the container body via a predetermined hinge portion, the lid is opened by rotating the operation component by a predetermined angle about the hinge portion. Since the spring means that urges the operation part in the direction in which the claw part engages is provided, the operation member is urged so as not to escape in the direction in which the claw part comes off, and the unintentional opening of the lid is more reliably prevented. Can do. In addition, when the operating part is operated beyond the position where the claw part disengages, the protruding part of the operating part from the outer surface of the container body comes into contact with the edge of the concave part of the container body, so that the operation of the operating part is restricted. Further, excessive deformation of the spring means for biasing the operation component can be prevented.

In the container with a lid of the present invention, a leaf spring-like spring part having a width in a direction perpendicular to the axis (AX) of the hinge part may be provided as the spring means. Moreover, in this case, the operation component may protrude from a position where the tip of the claw part on the opposite side of the hinge part is provided with the spring part .

As described above, according to the container with a lid of the present invention, since the claw portion can be engaged in two directions, the claw portion is not easily disengaged even if an impact or vibration is applied to the container, and the lid is not intended. Can be prevented. In addition, since the operating component operated to open the lid is biased in the direction in which the claw portion engages, the operating component inadvertently moves in the direction in which the claw portion disengages, and the lid is not intended. There is no risk of opening.

  1A and 1B are perspective views showing the appearance of a container according to an embodiment of the present invention. FIG. 1A shows a state in which the upper lid is closed, and FIG. 1B shows a state in which the upper lid is opened. 2 is a plan view, FIG. 3 is a partially broken front view, and FIG. 4 is a right side view. First, the outline of the container 1 will be described with reference to these drawings.

  As shown in FIG. 1, a container 1 with a lid according to this embodiment includes a container main body 2, a bottom lid 3 disposed on the bottom surface side of the container main body 2, and the top surface side of the container main body 2 (the upper surface in FIG. And an upper lid 4 disposed on the side). The lower end of the container body 2 opens almost entirely, and the opening is closed by the bottom lid 3. By removing the bottom cover 3, a wet tissue package is mounted inside the container body 2.

  FIG. 5 is a cross-sectional view of the package. The package 100 is a well-known package in which a large number of wet tissues 102... 102 are folded and accommodated inside a bag 101 having a sealing property so that a predetermined number (for example, one) can be continuously taken out from the opening 103. It is. The opening 103 is closed with a seal 104, and the seal 104 is peeled off during use (that is, when accommodated in the container 1).

  As is clear from FIG. 1 (b), an outlet 10 is formed in the upper part of the container body 2. The wet tissue 102 accommodated in the package 100 in the container 1 is pulled out by a predetermined number from the outlet 10. As is well known, the take-out port 10 is provided with flaps 11... 11 for holding the end of the next wet tissue 102 that is pulled up as the wet tissue 102 is taken out. The shape of the flap 11 is not limited to that shown in the figure, and various changes may be made. When the opening 103 of the package 100 is provided with a function equivalent to the flap 11, the flap 11 may be omitted.

  The upper lid 4 is pivotally attached to the container body 2 by the rear end portion being hinged to the container body 2. A leaf spring 5 is disposed between the container body 2 and the upper lid 4 as lid urging means for urging the upper lid 4 to a position where the upper lid 4 is opened. A push button 6 is attached to the front side of the container body 2. The push button 6 functions as a holding unit that holds the upper lid 4 in a closed position against the force of the leaf spring 5 and a release operation unit that is operated to open the upper lid 4. In the container 1 described above, the container body 2, the bottom lid 3, the upper lid 4 and the push button 6 are resin molded products, and the leaf spring 5 is preferably made of natural or synthetic rubber. However, the container of this invention is not limited to what was comprised with these materials. For example, the leaf spring 5 may be formed using spring steel or the like instead of the rubber material. The lid biasing means is not limited to a plate-like one.

  Next, external features of the container 1 will be described. As shown in FIG. 1A and FIG. 2 with hatching, the upper lid 4 has a rectangular plane that is substantially parallel to the bottom surface (surface formed by the bottom lid 3) of the container 1 when closed. Part 7 is provided. The flat portion 7 is provided to ensure stability when the containers 1 are stacked in the vertical direction. Moreover, the plane part 7 functions suitably also as a surface which affixes various labels. The flat surface portion 7 is also suitable as a mounting position of a so-called in-mold label that is arranged in advance in a mold and integrated with a resin molded product.

  On the other hand, side surfaces 12a, 12b, 12c and 12d (side surfaces 12b and 12c do not appear hidden behind in FIG. 1) are provided on the front, rear, left and right of the container body 2, and the flat surface portion 7 of the upper lid 4 and the container body 2 Curved surface portions 8a, 8b, 8c, 8d are arranged between the front, rear, left and right side surfaces 12a-12d. Each curved surface portion 8 a, 8 b, 8 c, 8 d extends over both the upper lid 4 and the container body 2. In other words, a part of the curved surface portions 8 a to 8 d is distributed to the upper lid 4 and the remaining portion is distributed to the container body 2.

  In the figure, for convenience of understanding, the boundary portions of the curved surface portions 8a to 8d, the mutual boundary portions of the side surfaces 12a to 12d, and the boundary portions of the curved surface portions 8a to 8d and the side surfaces 12a to 12d are respectively shown. Although contour lines are drawn, actually curved surfaces are also arranged in these contour portions. In order to impress the stability of the container 1, the side surfaces 8 a to 8 d of the container body 2 are inclined or curved so that the horizontal cross section of the container 1 gradually decreases toward the upper side. When the width W, depth D, and height H (see FIGS. 2 to 4) of the container 1 are about 170 × 110 × 70 mm, the curvature radii of the curved surface portions 8a to 8d are set to at least 30 mm or more. However, the curved surface portions 8a to 8d may be configured by joining two or more curves having different curvature radii. In addition, it is desirable that the area of the flat portion 7 is 20% or more with respect to the area of the bottom surface of the container 1. In addition, it is desirable to provide the plane part 7 in the center part of the container plane. The shape of the flat portion 7 is not limited to a rectangular shape, and can be provided in various shapes.

  A stack line 13 is provided below the container body 2 so as to go around the container body 2. The stack line 13 is formed by shifting the side surfaces 12a to 12d of the container body 2 outward by a predetermined amount. As is clear from FIG. 6A showing the enlarged VI portion of FIG. 3, convex portions 14 are formed at the four corners of the lower end inner surface of the container body 2. When the container body 2 is stacked up and down, the stack line 13 of the lower container body 2 and the convex portion 14 of the upper container body 2 come into contact with each other as shown in FIG. Thereby, the container main body 2 can be piled up orderly by the fixed space | interval to the up-down direction. In addition, as shown in FIG. 7, the positional relationship between the stack line 13 and the convex portion 14 can stack the subassembly 9 combining the container body 2, the upper lid 4, the leaf spring 5, and the push button 6 in the vertical direction. It is determined as follows.

  The connecting portion between the container body 2 and the bottom lid 3 is configured as shown in FIG. That is, a rib 15 having an enlarged tip and a flange 16 protruding outward from the rib 15 are formed at the lower end of the container body 2. On the outer periphery of the bottom lid 3, a groove portion 3 a for receiving the rib 15 is formed so as to go around the bottom lid 3. By inserting the rib 15 into the groove 3 a, the wall 3 b on the outer peripheral side of the groove 3 a meshes with the enlarged portion of the rib 15, whereby the bottom cover 3 is held without dropping off from the container body 2.

  Next, the relationship between the container body 2 and the upper lid 4 will be described. 8 is a cross-sectional view taken along line VIII-VIII in FIG. 3, FIG. 9 is a plan view of the container 1 in which the upper lid 4 and the leaf spring 5 are omitted, and FIG. 10 is an enlarged view of a portion X in FIG. For reference, details of the upper lid 4 are shown in FIGS. 11 is a plan view of the upper lid 4, FIG. 12 is a front view of the upper lid 4, FIG. 13 is a rear view of the upper lid 4, FIG. 14 is a right side view of the upper lid, FIG. 15 is a rear view of the upper lid 4, and FIG. FIG. 17 is an enlarged cross-sectional view of the rear end portion of the upper lid 4.

  As shown in FIGS. 8 and 9, a first concave portion (top surface-side concave portion) 21 is formed on the top surface side of the container body 2 so as to match the outer periphery and the shape of the upper lid 4. The bottom plate 21a of the first recess 21 is parallel to the bottom surface of the container 1, and the side plate 21b is substantially orthogonal to the bottom plate 21a. The bottom plate 21 a is formed with a second recess 22 that is one step lower than the first recess 21. The outlet 10 and the flap 11 described above are formed in the bottom plate 22 a of the second recess 22. The bottom plate 22a of the second recess 22 is also parallel to the bottom surface of the container 1, and the side plate 22b is substantially orthogonal to the bottom plate 22a. The second recess 22 is formed in an oval shape or an oval shape as a whole. As well shown in FIG. 1B and FIG. 15, an oval or oval closing rib 40 corresponding to the second recess 22 is formed on the back surface of the upper lid 4. As shown in FIGS. 8 and 10, when the upper lid 4 is closed, the closing rib 40 enters immediately inside the side plate 22 b of the second recess 22. As a result, the periphery of the outlet 10 is doubly surrounded by the closing rib 40 and the side plate 22b, and a practically sufficient sealing property is secured with respect to the periphery of the outlet 10 of the container 1.

  As shown in FIGS. 14 and 15, the closing rib 40 extends over the flat surface portion 7 of the upper lid 4 and the front and rear curved surface portions 8 a and 8 b. That is, the closed shape drawn by the closing rib 40 extends over the flat surface portion 7 and the curved surface portions 8a and 8b. Therefore, the flat surface portion 7 and the curved surface portions 8 a and 8 b are integrated by the closing rib 40, and practically sufficient rigidity is given to the upper lid 4. Further, the use of the container 1 can be improved by enlarging the closing rib 40 without being affected by the size of the flat portion 7, thereby reducing the frequency with which the wet tissue 102 is bitten. A reinforcing rib may be provided on the back surface of the upper lid 4 in addition to the closing rib 40.

  As apparent from FIGS. 11 and 15, the outer periphery of the upper lid 4 has a curved portion 41 extending in a gentle curve from the front end of the upper lid 4 toward the left and right rear ends, and both ends of the curved portion 41 are linear. And a rear end portion 42 connected to each other. The curved portion 41 extends in a contour similar to that of the side plate 21b of the first recess 21 of the container main body 2, thereby minimizing the gap between the upper lid 4 and the container main body 2 when the upper lid 4 is closed. Thus, the sense of unity of the curved surface portions 8a to 8d is improved. And the claw part 43 which meshes with the push button 6 (refer FIG. 1) is provided in the front end of the curved part 41 (refer FIG. 16).

  The curved portion 41 extends to the curved surface portion 8b on the back side of the container body 2. Further, parallel portions 41a and 41a that are parallel to each other are provided at the rear end (lower end in FIG. 15) of the bending portion 41, and hinge shafts 44 and 44 are provided on these parallel portions 41a. The hinge shafts 44 and 44 are coaxial with each other, and the axis thereof is parallel to the direction in which the rear end portion 42 extends. As is clear from FIG. 17, the rear end portion 42 is provided with a stopper flange 45 that extends downward beyond the axis of the hinge shaft 44 with the upper lid 4 closed. Further, two hollow bosses 46, 46 for attaching the leaf spring 5 are provided on the back surface of the upper lid 4. The width W2 between the parallel portions 41a and 41a is set to 85% or more with respect to the maximum width W1 of the upper lid 4.

  On the other hand, as is apparent from FIGS. 8 and 9, a third recess (back recess) 23 for receiving the rear end of the upper lid 4 is formed on the back side (right end in FIG. 8) of the container body 2. Has been. Since the rear end portion 42 of the upper lid 4 is deviated below the plane portion 7 due to the presence of the curved surface portion 8 b, the bottom plate 23 a of the third recess 23 is positioned lower than the bottom plate 21 a of the first recess 21. . Bag-shaped hinge receiving holes 24, 24 that do not penetrate are formed at both ends of the third recess 23. By attaching the hinge shaft 44 of the upper lid 4 to these hinge receiving holes 24, the upper lid 4 is attached to the container body 2 so as to be openable and closable as shown in FIG. Note that stoppers 25, 25 are formed in the third recess 23 (see FIG. 9). As shown in FIG. 18 (b), when the upper lid 4 is opened until the flat surface portion 7 is substantially perpendicular to the bottom surface of the container 1, the front end surface 45 a of the stopper flange 45 comes into contact with the stopper 25, and the upper lid 4 is further increased. Is prevented from opening. Thereby, the open / close range of the upper lid 4 is limited to an appropriate range. However, the opening restriction position by the stopper 25 is not limited to the position where the flat surface portion 7 is orthogonal to the bottom surface of the container 1, and may be appropriately set according to the usage form of the container 1.

  As shown in FIG. 9, a spring mounting hole 26 for mounting the leaf spring 5 is formed in the approximate center of the bottom plate 23 a of the third recess 23. A spring accommodating portion 27 is provided in front of the spring mounting hole 26 so as to expand the third recess 23 forward. The width in the left-right direction of the spring accommodating portion 27 is somewhat larger than the width in the same direction of the leaf spring 5. The side plate 27 a at the front end of the spring accommodating portion 27 is flush with the side plate 22 b of the second recess 22. As shown in FIGS. 18A and 18B, one end of the leaf spring 5 is inserted into the spring mounting hole 26, and the other end is attached to the boss 46 of the upper lid 4. A cap 47 for preventing the leaf spring 5 from coming off is attached to the boss 46.

  As shown in FIG. 18A, when the upper lid 4 is closed, the leaf spring 5 is accommodated in the spring accommodating portion 27 in such a posture that the folded portion 5a protrudes to the front side of the container 1. On the other hand, as shown in FIG. 18B, when the upper lid 4 is opened, the leaf spring 5 is drawn upward from the spring accommodating portion 27. Even in this case, the leaf spring 5 has an arc that swells in front of the container 1. It is drawn and curved. Therefore, even if the rear end portion 42, particularly the stopper flange 45, enters the third recess 23 with the opening of the upper lid 4, there is no possibility that the stopper flange 45 of the upper lid 4 and the leaf spring 5 interfere with each other. Moreover, the spring mounting hole 26 is substantially at the same position as the stopper 25, and the leaf spring 5 pulled out from the spring mounting hole 26 escapes to the front side of the container 1 from the front end surface 45 a of the stopper flange 45 contacting the stopper 25. Yes. Thereby, interference with the leaf | plate spring 5 and the rear-end part 42 of the upper cover 4 is avoided more reliably.

  As shown in FIGS. 8 and 18, a boss 28 corresponding to the spring mounting hole 26 is formed on the inner surface side of the container body 2 so as to protrude. The boss 28 protrudes further downward from the bottom plate 23 a of the third recess 23 formed deeper than the first recess 21 in accordance with the provision of the curved surface portion 8 b on the upper lid 4. The semi-circular ribs 29 and 29 are provided on both sides of the boss 28 so that the boss 28 does not come into contact with the bag 101 of the package 100 and the bag 101 is not torn. Note that the shape of the rib 29 is not limited to a semicircular shape, and any shape may be used as long as a shape that widens toward the base from the tip of the boss 28 is provided around the boss 28.

  As shown in FIG. 8, the push button 6 is mounted in the button mounting recess 30 of the container body 2. FIGS. 21 and 22 are enlarged views of the mounting portion of the push button 6, FIG. 21 is a plan view, and FIG. 22 is a cross-sectional view. For reference, details of the vicinity of the button mounting recess 30 of the container body 2 are shown in FIGS. 23 and 24, and details of the push button 6 are shown in FIGS. Further, FIG. 30 shows a state in which the meshing portion between the push button 6 and the upper lid 4 is enlarged.

  As is clear from FIGS. 25 to 29, the push button 6 includes a top plate portion 61 and a peripheral plate portion 62 that extends along the periphery of the top plate portion 61. The top surface of the top plate portion 61 functions as an operation surface 61a for a user to attach a finger. The operation surface 61a is formed to draw a curved surface with a concave center. An outer periphery 61 b on the front end side (lower side in FIG. 25) of the top plate portion 61 is curved in an arc shape, and an outer periphery 61 c on the rear end side is formed in a concave shape in accordance with the curved portion 41 of the upper lid 4. A claw part 63 for engaging with the claw part 43 of the upper lid 4 is formed at the center of the rear end part of the top plate part 61. In addition, hinge shafts 64 and 64 are formed at the left and right ends of the peripheral plate portion 62. The hinge shafts 64 are coaxial with each other. Further, a spring portion 65 is formed below the top plate portion 61. The spring portion 65 has an arcuate shape, and both ends 65 a and 65 a are integrally joined to the peripheral plate portion 62. The axis of the hinge shafts 64, 64 and the string of the spring portion 65, that is, the line connecting both ends 65a, 65a of the spring portion 65 are parallel to each other.

  In order to suppress plastic deformation of the spring portion 65, the length of the spring portion 65 is preferably as long as possible. On the other hand, since the outer periphery 61b on the front end side of the top plate portion 61 is curved in an arc shape, the width in the left-right direction of the push button 6 decreases toward the front end. Therefore, the joining position between the both ends 65 a and 65 a of the spring portion 65 and the peripheral plate portion 62 is set to a position slightly retracted from the front end of the push button 6. When the push button 6 is injection-molded, if the resin flows merge in a cavity complementary to the spring portion 65 in the mold, a joint surface of the resin is formed at the merged position, and the strength of the portion is increased. There is a risk of lowering and affecting the durability of the spring portion 65. Therefore, in the mold for forming the spring portion 65, it is desirable to determine the resin injection gate position so that the injected resin flows from one of the cavities for forming the spring portion 65 to the other.

  On the other hand, as shown in FIGS. 23 and 24, the button mounting recess 30 of the container body 2 includes a bottom plate 30 a lower than the bottom plate 22 a of the second recess 22, and the bottom plate 30 a and the bottom plate 21 a of the first recess 21. The side plate 30b is disposed between the bottom plate 30a and the curved surface 8a. The side plate 30 c is curved along the outer periphery 61 b of the push button 6, and bag-like hinge receiving holes 31, 31 for receiving the hinge shaft 64 of the push button 6 are formed at the left and right ends thereof. Further, the bottom plate 30a is provided with a spring receiving groove 32 for receiving the spring portion 65 of the push button 6, and the center 65b (see FIG. 26) of the spring portion 65 is constrained to a predetermined position in the groove 32. The rib 33 is provided.

  As shown in FIGS. 21 and 22, the push button 6 has the spring shaft 65 fitted into the spring receiving groove 32 and the hinge shaft 64 fitted into the hinge receiving hole 31 so that the hinge shaft 64 is centered in the button mounting recess 30. It is mounted so as to be rotatable. Due to the restoring force of the spring portion 65, the push button 6 is urged in the direction approaching the first recess 21 (in the direction of arrow R1 in FIG. 22) about the hinge shaft 64. When the upper lid 4 is closed, the push button 6 rotates in the direction of arrow R2 in FIG. 22 so as to avoid the claw portion 43 of the upper lid 4. When the claw portion 43 gets over the claw portion 63, the push button 6 is rotated by the force of the spring portion 65, whereby the claw portions 63 and 43 are engaged with each other and the upper lid 4 is closed as shown in FIG. Is kept in the state.

  In a state where the upper lid 4 is closed, when a plane including an arc formed by the spring portion 65 is imagined, the rib 33 constrains the spring portion 65 so that the plane is substantially parallel to the push-down direction of the push button 6. . For this reason, the direction of elastic deformation of the spring portion 65 is maintained in a direction that pushes and expands the arc formed by the spring portion 65, and there is no possibility that inconveniences such as cutting of the spring portion 65 due to irregular deformation occur. . The means for holding the deformation direction of the spring portion 65 in a predetermined direction is not limited to the rib 33 and may be variously changed. For example, the entire groove 32 may be set to have substantially the same width as the spring portion 65, and the deformation direction of the spring portion 65 may be limited by the groove 32 itself.

  As shown in detail in FIG. 30, the claw portion 43 has a shape that extends to the apex (tip) AP along the opposing surface 63 a of the claw portion 63 and further wraps around the back surface 63 b side of the claw portion 63 beyond the apex AP. Is formed. Due to such a meshing structure, the possibility that the upper lid 4 opens accidentally when the container 1 or its subassembly 9 is dropped or the like is reduced. That is, according to the container 1 of the present embodiment, the claw portions 63 and 43 are engaged not only in the vertical direction but also in the front-rear direction, so that the upper lid 4 is less likely to be opened accidentally, and is caused by unintentional opening of the upper lid. Transport errors can be prevented and production efficiency can be improved.

  Furthermore, in the container 1 of the present embodiment, as shown in FIG. 30, the axis AX of the hinge shaft 64 serving as the rotation center of the push button 6 is below the region P where the claws 63 and 43 mesh with each other. It ’s far away. By setting the positional relationship between the meshing region P and the shaft center AX in this way, the claw portion 63 escapes in both the upper and front directions of the container 1 with respect to the claw portion 43 when the push button 6 is pressed. Become. Therefore, despite the shape in which the claw portion 43 is engaged so as to embrace the claw portion 63, the engagement of the claw portions 63, 43 can be reliably removed by a simple operation by simply pushing down the push button 6. Can be released.

  22, the front end 6a of the push button 6 protrudes from the outer surface of the container body 2. When the push button 6 is pushed down, the front end 6a abuts against the stopper edge 30d of the button mounting recess 30, thereby restricting the push-down operation of the push button 6. As described above, since the operation amount of the push button 6 is limited to the predetermined range, it is possible to reliably eliminate the possibility that the spring portion 65 is excessively bent to cause plastic deformation.

  The front end portion of the push button 6 protrudes from the outer surface (here, the curved surface portion 8a) of the container body 2 in the entire operation range of the push button 6. Accordingly, the upper lid 4 can be opened by hooking the palm or back of the palm or other parts on the push button 6 without attaching a finger to the operation surface 61a. If importance is attached to such operability, for example, as shown in FIG. 31, a protrusion 61d is formed on the operation surface 61a of the push button 6 so that the user can more easily hook a part such as a finger. Good. However, it is not necessary that a part of the push button 6 protrudes from the outer surface of the container 1 in the entire operation range of the push button 6, and the position where the claws 63 and 43 are disengaged, that is, the locus of the nail 43 in FIG. It is only necessary that a part of the push button 6 protrudes from the outer surface of the container 1 when the push button 6 is operated to a position where the line 48 and the claw portion 63 are in contact with each other.

  On the other hand, if the push button 6 protrudes from the outer surface of the container 1, the push button 6 may be pushed carelessly, or the surrounding object may come into contact with the push button 6 and the upper lid 4 may be opened unintentionally. There is also. In order to prevent such unintentional opening of the upper lid 4, when the push button 6 is operated to a position where the claws 63 and 43 are disengaged, the entire push button 6 is inside the outer surface of the container 1. It is better to configure it so that it is hidden behind.

  In the container 1 described above, the spring portion 65 may be separated from the push button 6 and biased to a position where the push button 6 is closed by another spring member. Even if the push button 6 is integrated with the container body 2 and the thickness of the portion connecting the push button 6 and the container body 2 is adjusted so that the center of rotation coincides with the position corresponding to the hinge shaft 64. Good. The hinge shaft 44 of the upper lid 4 may be coupled to the container body 2 on the back side of the container 1 or may be coupled on the top surface side. The number of leaf springs 5 may be two or more. The hinge shaft 44 and the hinge receiving hole 24, and the hinge shaft 64 and the hinge receiving hole 31 may have opposite relations between the shaft and the hole, respectively.

  In the above embodiment, the terms top, bottom, side and top lid are merely relative to the position of each part relative to the case where the container is installed with the outlet facing upward, The position of each part at the time of use is not limited by these terms. For example, the container with a lid of the present invention may be used in a state in which the outlet is turned sideways.
