DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
The container holding part described in 1 is provided with a claw part 2 provided on an operation part 201 integrated with the container body 200 as shown in FIG.
02 and a claw portion 204 provided on the upper lid 203 are vertically engaged with each other to hold the upper lid 203. Operation part 2
When the user pushes the tip of 01, the claw portion 202 on the main body side
Is retracted from the upper lid 203, whereby the constraint of the upper lid 203 is released and the upper lid 203 is opened.

However, the above-mentioned claw portion 202,
In the structure in which the 204 are meshed with each other, when some impact is applied to the container, the claws 202 and 204 are easily disengaged, and the upper lid 203 is opened by the spring force. If such a phenomenon occurs when the container bodies with the upper lids are mounted one by one on the production line and transported, the transporting posture of the container body is not stable, resulting in defective transport.

Further, in Japanese Unexamined Patent Publication No. 9-58725 (hereinafter referred to as prior art 2), an opening operation member having a claw portion that meshes with a claw portion of an upper lid is hinge-coupled to a container body, A container is disclosed in which a spring member provided on the operating member urges the opening operating member in a direction in which the claw portions are engaged with each other. However, the claw portion of the container is the same as that shown in FIG. 32, and the engagement is still likely to be disengaged. Moreover, in the container of the prior art document 2, the opening operation member is provided with a flange for pushing up the claw portion of the upper lid. Therefore, when the operation member rotates due to the impact when the container is dropped, a force for pushing up the upper lid is generated, and the force acts so as to disengage the claw portions from each other, so that the upper lid may be more easily opened. Further, since the spring portion of the opening operation member is provided in a cantilever state, there is concern about the strength of the spring portion against repeated use.

Japanese Unexamined Patent Publication No. 2000-211661 (hereinafter referred to as prior art 3) discloses that the upper lid and the container body are provided with claw portions for holding the upper lid in a closed state, and the container body is opened. There is disclosed a container in which an operating member for use is attached via a hinge. In this container, the pushing operation of the operating member is transmitted as an upward force to the upper lid, whereby the claw portion on the upper lid side gets over the claw portion on the container body side and the restraint of the upper lid is released. The operating member is integrally formed with a spring member for holding the operating member 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 claw portions against each other.

An object of the present invention is to provide a container with a lid which can surely restrain the lid covering the outlet of the contents with respect to the container body and prevent the lid from being unintentionally opened due to vibration or the like.

Further, according to the present invention, in the case of rotatably attaching an operation part operated to open the lid to the container body, the operation part is inadvertently moved in a direction to disengage the claw portion and the lid is moved. It is also an object of the present invention to provide a container with a lid that is unlikely to be unintentionally opened, and an operating component suitable for use in the container with a lid.

[0009]

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

The lidded container of the present invention is connected to a container body (2) having an outlet (10) for contents and is connected to the container body via a hinge part (44) so that the outlet can be closed. A lid (4) and a lid urging means (5) arranged between the container body and the lid to urge the lid in an opening direction are provided, and the lid side and the container body side are respectively provided. A pair of claws (43, 63) provided can be engaged with each other to be restrained at a position for closing the lid, and the claws of the claw can be operated by operating an operation section (6) provided on the container body or the lid. In the container (1) with a lid that can be disengaged,
One of the pair of claws (43)
Has a shape that extends along the facing surface (63a) of the other claw portion (63) to the tip (AP) of the other claw portion and further wraps around the back surface (63b) side beyond the tip. It is characterized by that.

According to the container with a lid of the present invention, the claw portions can engage with each other in two directions. Therefore, even if impact or vibration is applied to the container, the engagement of the claw portions is unlikely to be disengaged, and it is possible to prevent unintended opening of the lid.

In the lidded container of the present invention, the claw portion is provided on each of the lid side and the container body side. However, in addition to the case where the claw portion is provided on the lid or the container body itself, the claw portion is provided on the lid or the container body. The claw portion may be provided on another component to be mounted. For example, when another component that functions as an operation unit is mounted on the container body and a claw portion is provided on the other component, the claw portion of the other component corresponds to the claw portion on the container body side. The operation unit may be on the lid side.

In the lidded container of the present invention, the operating portion may be provided integrally with the container body or the lid, or may be provided as a separate component. As a preferable mode when provided as a separate component, a rotatable operation component (6) is attached to the container body via a predetermined hinge portion (64), and the operation component functions as the operation component. You may do it. In this case, the lid is opened by rotating the operation component by a predetermined angle around the hinge portion.

Furthermore, in the container with a lid of the present invention,
Spring means (65) for urging the operation part in a direction in which the claw portion is engaged may be provided. With this, the operation member is biased so as not to escape in the direction in which the claw portion comes off, and it is possible to more reliably prevent unintentional opening of the lid.

The spring means may be formed integrally with the operating component. In particular, when the operation part is a resin molded product, the spring means is integrally molded, so that the number of parts can be reduced and the cost can be reduced.

The operation part may be provided with an operation surface (61a) for a user to touch, and the spring means may be provided on the back side of the operation part with respect to the operation surface.
In this case, the operation component can be biased in the direction of lifting the operation surface by the spring means. The lid is opened by pressing the operating surface against the spring means.

The spring means may be formed so that both ends (65a) thereof form an arc joined to the back surface side. In this case, since the spring means draws a closed shape, a spring having relatively high rigidity can be easily realized. Moreover, stress concentration is less likely to occur as compared with a cantilevered spring, and the life of the spring means is also improved. The straight line connecting both ends of the spring means may be parallel to the axis of the hinge portion of the operating component.

On the outer circumference of the operation surface, there is provided a curved portion (61b) which curves in an arc from the side on which the claw portion is provided to the tip on the opposite side. You may join to the said back surface side in the middle of a curved part. In this case, the spring means can be formed longer than the spring means provided at the tip position. Therefore, the internal stress generated in the spring is dispersed and the life of the spring means is improved.

The container body may be provided with a restricting means (33) which comes into contact with the spring means to restrict the elastic deformation direction of the spring means. As a result, the spring means can be prevented from elastically deforming in a direction that is disadvantageous in terms of strength, and the life of the spring means can be improved. Particularly when arc-shaped spring means is provided, the limiting means preferably limits the direction so that the spring means deforms along a plane including both ends and the center thereof.

Further, in the lidded container of the present invention, when an operating component, which is a component separate from the container main body, functions as an operating portion, the operating component (6) for the user to touch the operating component.
1a) may be provided, and its operation surface may draw a concave curved surface. In this case, it is convenient for the user to operate the operation component with his / her finger.

Further, the operating part is mounted in the recess (30) of the container body, and at least one of the operating parts is operated when the operating part is operated from a state where the claws are engaged to a position where the engagement is disengaged. The part (for example, 61d in FIG. 31) may protrude beyond the outer surface of the container body around the recess. In this case, since the operation component projects from the outer surface of the container body, it is easy to operate. In particular, there is an advantage that the lid can be opened even if the finger is not correctly attached to the operation surface and the palm or the back of the hand is attached to the protruding portion of the operation component to operate the operation component. Furthermore, when the operating component is operated beyond the position where the engagement of the claw portion is disengaged, the protruding portion of the operating component from the outer surface comes into contact with the edge (30d) of the concave portion of the container body, and If the operation is restricted, excessive deformation of the spring means can be prevented.

On the other hand, the operating part is mounted in the recess (30) of the container body, and when the operating part is operated to a position where the engagement of the claws is disengaged, the entire operating part is located around the recess. You may make it set inward rather than the outer surface of a container main body. In this case, the claw part cannot be removed unless it touches the operating component arranged in the recess, so that it may be inadvertently contacted with the operating component or some obstacle around the operating component may contact the operating component. There is no risk that the lid will be opened carelessly.

In a state in which the claw portion of the lid and the claw portion of the operating component are intermeshed with each other with the claw portion of the operating component facing up, the axis (A of the hinge portion of the operating component).
X) is preferably below the meshing portion (P) of the claw portion and laterally displaced from the lid. In this case, the movement of the operating part around the axis of the hinge part gives the claw part of the operating part an upward movement from the claw part on the lid side, and at the same time, the claw part on the lid side. The movement to move backward is given to the outside of the movement locus (48 in FIG. 30). Accordingly, even in the structure in which the operating component and the claw portion on the lid are engaged with each other as described above, the engagement can be easily disengaged only by rotating the operating component.

Another container with a lid of the present invention is connected to a container body (2) having an outlet (10) for contents and is connected to the container body via a hinge part (44) to close the outlet. A possible lid (4) and a lid urging means (5) arranged between the container body and the lid to urge the lid in an opening direction.
And an operating part (6) attached to the container body via a hinge part (64), and meshes a pair of claw parts (43, 63) provided on the lid and the operating part, respectively. In a container with a lid (1) that can be restrained to a position where the lid is closed by closing the lid, and the engagement of the claw portion can be released by operating the operation component, an operation surface for a user to touch the operation component ( 61a) is provided, and spring means (65) for urging the operation component in the direction in which the claws are engaged is provided on the back side of the operation surface, and the spring means has both ends (65a). It is characterized in that it is formed integrally with the operation component so as to draw an arc joined to the back surface side.

With this lidded container, the pawl portion of the operating member is urged in the direction in which it engages with the pawl portion on the lid side by the spring means formed integrally with the operating component. Therefore, unintentional opening of the lid due to the movement of the operating component in the direction in which the claw portion is disengaged due to vibration or impact is prevented. Moreover,
Since the spring means draws an arc in the closed shape, a spring having a relatively high rigidity can be easily realized. Moreover, stress concentration is less likely to occur as compared with a cantilevered spring, and the life of the spring means is also improved.

This lidded container can also include the same mode as the lidded container described above. That is, a straight line connecting both ends of the spring means may be parallel to the axis of the hinge portion of the operation component. A curved portion (61b) that curves in an arc from the side where the claw portion is provided toward the tip on the opposite side is provided on the outer periphery of the operation surface, and both end portions of the spring means have the curved portion. It may be joined to the back surface side on the way. The container body may be provided with a restricting means (33) that abuts on the spring means and restricts a direction of elastic deformation of the spring means. The limiting means may limit the direction such that the spring means deforms along a plane including both ends and a center thereof. The operation surface may draw a concave curved surface. The operating component is mounted in a recess of the container body, and when the operating component is operated from a state where the claws are engaged to a position where the engagement is disengaged, at least a part of the operating component is a container around the recess. It may project beyond the outer surface of the body.
When the operating component is operated beyond the position where the front claw portion is out of engagement, the protruding portion of the operating component from the outer surface comes into contact with the edge (30d) of the concave portion of the container body to operate the operating component. You may be limited. The operating component is mounted in the recess of the container body, and when the operating component is operated to a position where the engagement of the claw portion is disengaged, the entire operating component is located inside the outer surface of the container body around the recess. It may fit.

Further, the operating component of the present invention is a container (1).
A hinge part (64) for hinged connection to a specific component (2) of the above, and a claw part (4) capable of meshing with a mating part (4) provided to be openable and closable with respect to the specific component (4). 63) and an operation surface (61a) for the user to touch.
And a spring portion (65) which is provided on the back side of the operation surface and urges the claw portion in a direction in which the claw portion engages with a counterpart component,
The spring portion is integrally formed on the back surface side so that both ends (65a) of the spring portion draw an arc joined to the back surface side.

According to the present invention, it is possible to provide an operation component suitable for the above-mentioned lidded container.

In the operating component of the present invention, the straight line connecting both ends of the spring portion may be parallel to the axis of the hinge portion. A curved portion (61b) that curves in an arc from the side where the claw portion is provided toward the tip on the opposite side is provided on the outer periphery of the operation surface, and both end portions of the spring portion are of the curved portion. It may be joined to the back surface side on the way.
The operation surface may draw a concave curved surface. A protrusion (61d) may be provided on the operation surface.

In the figure, for convenience of understanding, the mutual boundary portions of the curved surface portions 8a to 8d, the mutual boundary portions of the side surfaces 12a to 12d, and the curved surface portions 8a to 8d and the side surfaces 12a to 1 are shown.
A contour line is drawn on each of the boundaries with 2d,
In reality, curved surfaces are also arranged in these contour portions. In addition, in order to give a sense of stability of the container 1, the side surfaces 8a to 8d of the container body 2 are inclined or curved so that the horizontal cross section of the container 1 becomes gradually smaller toward the upper side. When the width W, the depth D, and the height H (see FIGS. 2 to 4) of the container 1 are set to approximately 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 radii of curvature. Further, it is desirable that the area of the flat surface portion 7 is 20% or more of the area of the bottom surface of the container 1. In addition, it is desirable that the flat surface portion 7 is provided in the central portion of the flat surface of the container. The shape of the flat surface portion 7 is not limited to a rectangular shape, and can be provided in various shapes.

0 is an enlarged view of the X portion of 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 4, FIG. 15 is a rear view of the upper lid 4, and FIG. 17 is an enlarged cross-sectional view of the front end portion of FIG. 17, and 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, on the top surface side of the container body 2, a first recess (top surface side recess) 21 is formed in conformity with the outer periphery 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. In the bottom plate 22a of the second recess 22, the above-mentioned outlet 1
0 and flap 11 are formed. 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 elliptical shape or an oval shape as a whole. FIG. 1 (b),
Further, as well shown in FIG. 15, an oval or elliptical 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 is used as the second recess 22.
It goes right inside the side plate 22b. 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 8a, 8b. That is, the closed shape drawn by the closing rib 40 extends across the flat surface portion 7 and the curved surface portions 8a and 8b. Therefore, the flat surface portion 7 and the curved surface portion 8
a and 8b are integrated by a closing rib 40, and the upper lid 4
To give sufficient rigidity for practical use. Also, the closing rib 40
Can be enlarged without being affected by the size of the flat surface portion 7, thereby reducing the frequency of occurrence of the biting of the wet tissue 102 and improving the usability of the container 1. 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 rear ends of the left and right sides, and both ends of the curved portion 41. Is connected in a straight line to the rear end portion 42 in combination. The curved portion 41 is the first recess 2 of the container body 2.
1 has a contour similar to that of the side plate 21b and extends, thereby minimizing the gap between the upper lid 4 and the container body 2 when the upper lid 4 is closed and improving the sense of unity of the curved surface portions 8a to 8d. I am letting you. A claw portion 43 that meshes with the push button 6 (see FIG. 1) is provided at the front end of the bending portion 41 (see FIG. 16).

The curved portion 41 extends to the curved surface portion 8b on the back side of the container body 2. In addition, the rear end of the bending portion 41 (see FIG.
At the lower end), parallel portions 41a, 41a parallel to each other
Are provided, and the hinge shafts 44, 4 are provided on the parallel portions 41a.
4 are provided. The hinge shafts 44, 44 are coaxial with each other, and their axes are parallel to the extending direction of the rear end portion 42. Further, as is apparent from FIG. 17, the rear end portion 42 is provided with a stopper flange 45 extending downward beyond the axial center of the hinge shaft 44 with the upper lid 4 closed.
Further, two hollow bosses 46, 46 for attaching the leaf springs 5 are provided on the back surface of the upper lid 4. The width W2 between the parallel portions 41a, 41a is set to 85% or more of the maximum width W1 of the upper lid 4.

On the other hand, as is clear from FIGS. 8 and 9,
A third recess (rear surface side recess) for receiving the rear end of the upper lid 4 is provided on the rear surface side (right end side in FIG. 8) of the container body 2.
23 is formed. The rear end portion 42 of the upper lid 4 is the curved surface portion 8
Because of the presence of b, the bottom plate 23a of the third recess 23 is located lower than the bottom plate 21a of the first recess 21 because the bottom plate 23a is displaced downward from the flat surface portion 7. Bag-shaped hinge receiving holes 24, 24 that do not penetrate are formed at both ends of the third recess 23. By mounting the hinge shaft 44 of the upper lid 4 in 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 plane portion 7 of the upper lid 4 is substantially orthogonal 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 to prevent further opening of the upper lid 4. As a result, the opening / closing range of the upper lid 4 is limited to an appropriate range. However, the opening limit 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 mode of the container 1.

As shown in FIG. 9, the bottom plate 2 of the third recess 23 is formed.
A spring mounting hole 26 for mounting the leaf spring 5 is formed at substantially the center of 3a. 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 of the spring accommodating portion 27 in the left-right direction is slightly larger than the width of the leaf spring 5 in the same direction.
The side plate 27a at the front end of the spring accommodating portion 27 is flush with the side plate 22b 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. Boss 4
A cap 47 for preventing the leaf spring 5 from coming off is attached to 6.

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-back portion 5a thereof is projected to the front side of the container 1.
On the other hand, as shown in FIG. 18 (b), when the upper lid 4 is opened, the leaf spring 5 is pulled out upward from the spring accommodating portion 27, but even in that case, the leaf spring 5 has an arc that bulges forward of the container 1. It is drawn and curved. Therefore, even if the rear end portion 42, especially the stopper flange 45 enters the third recess 23 with the opening of the upper lid 4, there is no risk of the stopper flange 45 of the upper lid 4 and the leaf spring 5 interfering with each other. Moreover, the spring mounting hole 26 is substantially at the same position as the stopper 25, and the leaf spring 5 drawn out from the spring mounting hole 26 is in contact with the stopper 25, and the tip surface 45a of the stopper flange 45 contacts the container 1 more.
Is running away to the front. As a result, the interference between the leaf spring 5 and the rear end portion 42 of the upper lid 4 is more reliably avoided.

As shown in FIGS. 8 and 18, the boss 2 corresponding to the spring mounting hole 26 is provided on the inner surface side of the container body 2.
8 is formed to project. The boss 28 projects further downward from the bottom plate 23 a of the third recess 23 formed deeper than the first recess 21 due to the curved surface portion 8 b provided on the upper lid 4. Such a boss 28 is the bag 1 of the package 100.
To prevent the bag 101 from breaking due to contact with 01, ribs 29, 29 having a substantially semicircular shape are provided on both sides of the boss 28. The shape of the rib 29 is not limited to the semicircular shape,
Any shape may be used as long as it gives a shape that widens toward the base from the tip of 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. Figure 2
1 and FIG. 22 are enlarged views showing the mounting portion of the push button 6, FIG. 21 is a plan view, and FIG. 22 is a 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 engaging portion between the push button 6 and the upper lid 4 is enlarged.

As is apparent from FIGS. 25 to 29, the push button 6 has a top plate portion 61 and a peripheral plate portion 62 extending along the periphery of the top plate portion 61. Top plate 61
The upper surface of the functions as an operation surface 61a for the user to put his / her finger on. The operation surface 61a is formed so as to draw a curved surface having a concave center. The front end side of the top plate portion 61 (see FIG. 25).
The outer periphery 61b on the lower side is curved in an arc shape, and the outer periphery 61c on the rear end side is formed in a recessed shape in accordance with the curved portion 41 of the upper lid 4. A claw portion 63 for engaging with the claw portion 43 of the upper lid 4 is formed at the center of the rear end portion of the top plate portion 61. The hinge shaft 6 is attached to the left and right ends of the peripheral plate portion 62.
4, 64 are formed. 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 is arcuate and has both ends 65.
The a and 65a are integrally joined to the peripheral plate portion 62. The axes of the hinge shafts 64, 64 and the chords of the spring portion 65, that is, the lines connecting the ends 65a, 65a of the spring portion 65 are parallel to each other.

In order to suppress the plastic deformation of the spring portion 65, it is preferable that the length of the spring portion 65 is long. On the other hand, the top plate 6
Since the outer circumference 61b on the front end side of 1 is curved in an arc shape, the width of the push button 6 in the left-right direction decreases toward the front end. Therefore, the joint position between the both ends 65a, 65a 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, when the resin flows merge in the cavity complementary to the spring portion 65 in the mold, a resin joint surface is formed at the merged position, and the strength of that portion is increased. There is a possibility that it may decrease and affect the durability of the spring portion 65.
Therefore, in the mold for forming the spring portion 65, it is desirable to determine the gate position for resin injection 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 is a bottom plate 30a lower than the bottom plate 22a of the second recess 22, and the bottom plate 30a and the first plate 30a.
Side plate 30b arranged between the recess 21 and the bottom plate 21a
And the side plate 3 arranged between the bottom plate 30a and the curved surface portion 8a.
It is surrounded by 0c. Side plate 30c has push button 6
The bag-shaped 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 along the outer circumference 61b. 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 restrained in a predetermined position in the groove 32. Ribs 33 are provided.

As shown in FIGS. 21 and 22, the push button 6 has a spring portion 65 fitted in the spring receiving groove 32 and a hinge shaft 64 fitted in the hinge receiving hole 31, whereby the push shaft 6 is inserted into the button mounting recess 30. It is mounted so as to be rotatable around 64. Due to the restoring force of the spring portion 65, the push button 6 is biased in the direction approaching the first recess 21 (the arrow R1 direction 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. Then, 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 mesh with each other and the upper lid 4 closes, as shown in FIG. Is kept in a closed state.

With the upper lid 4 closed, the spring portion 65
The rib 33 restrains the spring portion 65 such that when the plane including the arc formed by is virtual, 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 kept in a direction of expanding the arc formed by the spring portion 65, and there is no fear of causing inconvenience such as disconnection of the spring portion 65 due to deformation in an irregular direction. . The means for holding the deformation direction of the spring portion 65 in the predetermined direction is not limited to the rib 33 and may be variously modified. 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 extends to the apex (tip) AP along the facing surface 63a of the claw portion 63, and beyond the apex AP to the back surface 63b side of the claw portion 63. It is formed in a wraparound shape. Due to such a meshing structure, the risk of accidentally opening the upper lid 4 when the container 1 or its subassembly 9 is dropped is reduced. That is, according to the container 1 of the present embodiment, the claw portion 6
Since 3 and 43 are engaged not only in the vertical direction but also in the front-rear direction, there is little risk that the upper lid 4 will be opened accidentally, and it is possible to prevent a transport error due to the unintended opening of the upper lid and improve the production efficiency. .

Furthermore, in the container 1 of the present embodiment, FIG.
As shown in, the axis AX of the hinge shaft 64, which is the rotation center of the push button 6, is apart from the region P where the claws 63 and 43 mesh with each other downward and forward. By setting the positional relationship between the meshing region P and the axial center AX in this way, when the push button 6 is pressed, the claw portion 63 is pressed.
Can escape in both directions above and in front of the container 1 with respect to the claw portion 43. Therefore, even though the claw portion 43 is engaged with the claw portion 63 so as to embrace the claw portion 63, the claw portion 63,
The upper lid 4 can be opened by surely disengaging the engagement of 43.

Note that, as shown in FIG. 22, the front end portion 6a of the push button 6 projects from the outer surface of the container body 2.
When the push button 6 is pushed down, its front end portion 6a comes into contact with the stopper edge 30d of the button mounting recess 30,
As a result, the push-down operation of the push button 6 is restricted. Since the operation amount of the push button 6 is limited to the predetermined range as described above, it is possible to reliably eliminate the possibility that the spring portion 65 is excessively bent and plastically deformed.

The front end portion of the push button 6 projects beyond the outer surface (here, the curved surface portion 8a) of the container body 2 in the entire operation range of the push button 6. Therefore, without touching the operation surface 61a with a finger, the palm, the back, or other parts are hooked on the push button 6 and the upper lid 4
Can also be opened. If importance is attached to such operability, for example, as shown in FIG. 31, the push button 6
A protrusion 61d may be formed on the operation surface 61a so that the user can more easily hook a part such as a finger. However, part of the push button 6 does not have to protrude from the outer surface of the container 1 in the entire operation range of the push button 6, and the position where the claw portions 63 and 43 are disengaged, that is, the locus of the claw portion 43 in FIG. It suffices that a part of the push button 6 projects 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, when the push button 6 is projected from the outer surface of the container 1, the push button 6 is inadvertently pressed, or an object around the push button 6 comes into contact with the push button 6 and the upper lid 4 is unintentionally. It may be opened. In order to prevent such an unintended opening of the upper lid 4, the claw portion 6
Push button 6 to the position where the meshing of 3,43 is disengaged
When the button is operated, the entire push button 6 may be hidden inside the outer surface of the container 1.

In the container 1 described above, the spring portion 65 may be separated from the push button 6 and the push button 6 may be urged to a closed position by another spring member. Even if the push button 6 is integrated with the container main body 2 and the thickness of the portion connecting the push button 6 and the container main 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 connected to the container body 2 on the back surface side of the container 1 or may be connected to 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 shaft-hole relationships.

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

[0062]

As described above, according to the container with a lid of the present invention, the claws can be engaged in two directions, so that the claws are unlikely to be disengaged even if shock or vibration is applied to the container. Therefore, it is possible to prevent unintentional opening of the lid. Further, according to another container with a lid of the present invention, when the operation component operated to open the lid is rotatably attached to the container body, the operation component is careless in the direction of disengaging the claw portion. There is no risk that the lid will be unintentionally opened by moving to. Moreover, since the spring means draws an arc in a closed shape, a spring having a relatively high rigidity can be easily realized.
Stress concentration is less likely to occur as compared to a cantilevered spring, and the life of the spring means is also improved. Furthermore, according to the operating component of the present invention, an operating component suitable for the lidded container of the present invention can be provided.
