Description

  The present invention relates to a container with a lid that opens and closes the mouth of the container with a lid that can rotate around a hinge.

  As an example of this type of container with a lid, a container having an opening on its upper surface, a lid attached to the container via a hinge, and a locking operation member attached to the container via a second hinge The drink container provided is mentioned. When the locking operation member is rotated on the locking side in a state where the lid is in the closed position, the engagement portion of the locking operation member gets over the engagement portion of the lid and the both engagement portions are engaged with each other. By this engagement, the opening side rotation of the lid is regulated (see Patent Document 1).

JP 2007-217042 A

  As in the case of a container with a lid disclosed in Patent Document 1, in a state where a locking operation member is hung on the lid in a state where the lower end peripheral portion of the lid outer shell in the closed position and the upper end of the container outer shell abut, While the engaging portion of the operating member gets over the engaging portion of the lid, the lid cannot cause the closed side rotation. Therefore, it depends on the elastic deformation of both engaging parts and the locking operation member, and it is necessary to give the locking operation member an operating force corresponding to this. Furthermore, since both the engaging portions are made of plastic or metal, the larger the operation force, the more the deterioration such as strain accumulation and wear occurs during repeated use. Further, the operating force may be larger than the design value due to the influence of molding errors of the lid outer shell part and the container outer shell part. These problems similarly occur in containers with different lids in that the locking operation member is mounted on the lid.

  In view of the above-described circumstances, an object of the present invention is to provide an operation for causing the engaging portion of the locking operation member to get over the mating engagement portion in the container with the locking operation member that holds the lid in the closed position. In addition to reducing the force, it is intended to reduce the increase in the operating force due to the influence of molding errors of the lid and the container.

  In order to solve the above problems, the present invention includes a lid mounted on a container via a hinge, and a locking operation member mounted on one side of the container and the lid via a second hinge, When the locking operation member is rotated on the locking side in a state where the lid is in the closed position, the engagement portion of the locking operation member gets over the engagement portion on the other side of the container and the lid. In a container with a lid in which the part is engaged and the opening-side rotation of the lid is restricted by the engagement, the container is interposed between the lid rotated around the hinge from the open state to the closed position and the container. The elastic body is compressed by the closing side rotational force applied to the lid as it gets over, and the lid is rotated by the closing side. The both engaging portions are hooked by being rotated open. Ri was the configuration adopted to suit.

  According to the configuration of the present invention, the lid is not directly supported by the container in a state where the lid is rotated from the open state to the closed position, and the elastic body is interposed between the lid and the container. When the locking operation member is rotated on the locking side in this state, the lid is pulled toward the container side as the engaging portion of the locking operation member gets over the engaging portion on the other side. Power is given. As a result, the elastic body interposed between the lid and the container is compressed. By this compression, the lid is further rotated on the closed side from the closed position. The elastic body gradually repels according to the degree of overcoming of the engaging portion of the locking operation member. Along with this repulsion, the lid is rotated on the open side, whereby the engaging portions are engaged. In this way, the operation force when getting over is reduced by using the compression of the elastic body, not the elastic deformation of both engaging parts, to make the engaging part of the locking operation member get over the other engaging part. can do. As a result, deterioration of both engaging parts can be prevented. Further, even when the engagement margin between the engaging portions becomes large due to the molding error of the lid or the container, the influence of the molding error is mitigated by the compression of the elastic body. For this reason, it can reduce that the operation force at the time of getting over becomes large.

  Like a portable beverage container, a container with a lid that requires a reliable sealing of the container and can be applied unexpectedly with an external force that compresses the elastic body on the lid or container with the locking operation member applied. The locking operation member according to the present invention can be employed as a preliminary locking device.

  For example, when the lid rotated around the hinge from the open state to the closed side passes the closed position, it automatically enters the state where the open side rotation exceeding the closed position is restricted, and the restriction is released upon receiving a release operation. The elastic body can employ a configuration comprising a rubber packing that seals the container in a state in which the opening / closing operation member is restricted and the lid is rotated from the closed position to the closed side. . Here, the “rubber packing” is a rubber seal member formed by molding and used by being pressed against a seal surface.

  When the lid that is rotated from the opened state to the closed side passes the closed position, the opening / closing operation member automatically regulates the open side rotation of the lid beyond the closed position. Since the rubber packing seals the container in a state where the lid is restricted to the closing position by the opening / closing operation member, there is no fear of sealing leakage even if the latching operation member is detached. If the rubber packing seals the container even when the lid is rotated from the closed position to the closed side, there is no risk of leakage even if the lid is rotated from the closed position to the closed side by an unexpected external force. Therefore, the rubber packing can be used as an elastic body, and it is not necessary to add a dedicated component as an elastic body.

  It is preferable that one side of the container and the lid and the locking operation member have a resistance contact portion as long as the release side rotation from the rotational position where the engagement portions can be engaged is restricted. Here, “autorotation” refers to rotation that can occur due to rotational torque due to the weight of the locking operation member.

  The relative positional relationship between the one side on which the locking operation member is mounted and the locking operation member in the direction perpendicular to the rotation axis of the second hinge is before and after the engagement between the engagement portions is released due to unexpected external force. It does not change. For this reason, the release-side rotation from the rotational position where the engaging portions can be engaged with each other can be regulated by a simple means that simply provides a resistance contact portion on one side of the container and the lid and the locking operation member. . By restricting the release side rotation in this way, even if the engagement between the two engaging portions is released due to an unexpected external force as described above, the two engaging portions can be engaged again after the unexpected external force disappears. . Therefore, it is possible to prevent the latching operation member from being unexpectedly detached. Since the lid is restricted to the closing position by the opening / closing operation member, the lid is not restricted to the closing position by the locking operation member even when the engagement between both the engaging portions is released. For this reason, it is not necessary to restrict the release-side rotation of the locking operation member by an external force with the resistance contact portion, and if the release-side rotation can be restricted, the re-engagement of both engaging portions can be improved. In addition, it is possible to provide a freely rotating area of the locking operation member in an appropriate rotation area outside the resistance contact portion so that the locking operation member can be moved lightly. If it is a rotation prevention grade, the operation force for letting a resistance contact part pass will not be a problem.

  When the lid is rotated from the open state to the closed side while the locking operation member is stopped at the rotational position where the engagement portions can be engaged with each other, the locking operation member is pushed by the lid and released. More preferably, it is rotated.

  When the resistance contact portion is employed, it is possible that the locking operation member stays at the rotational position where the engagement portions can be engaged independently even if the lid is not in the closed position. There is a concern that the lid can be inadvertently rotated from the opened state to the closed side in this stopped state. If the locking operation member in the stopped state is pushed by the closing-side rotating lid to be rotated on the releasing side, the collision between the locking operation member and the lid can be released and the breakage can be prevented.

  Further, the container is composed of a beverage container having a mouth portion on the upper surface, and one side of the container and the lid is the container, and the stop position of the release side rotation of the locking operation member is The container and one side of the lid and the locking operation member have a second resistance contact portion that restricts the locking side rotation from the stop position. A configuration can be employed. Here, the concept of up and down refers to a direction that goes up and down when the container is placed on a horizontal surface with the lid in the closed position.

  Since the sealing of the container is ensured by the opening / closing member, the container can be a beverage container. A beverage container generally has a mouth provided on the upper surface. When this type of container is used, by opening the lid and tilting the container, the beverage remaining in the container may be discharged from the mouth, or the lip may be attached to the mouth and the beverage may be poured into the mouth. . When the container is tilted, if the locking operation member rotates on the locking side according to the inclination angle, the locking operation member gradually approaches the mouth, touching the beverage to be discharged, or touching the chin. There is concern. If the stop position of the release side rotation of the locking operation member is determined by contact with the side surface of the container, the locking operation member can be stopped at the position farthest from the mouth. Moreover, the 2nd resistance contact part which controls the latching side rotation from the stop position can be set to a container and a latching operation member. By regulating in this way, it is possible to prevent the locking operation member from drooping when the container is tilted by simple means, and contact with the beverage or chin can be avoided.

  Further, the container is provided with a shaft support portion that is inserted through the rotation shaft of the second hinge, and a portion of the outer surface of the shaft support portion on a line that is orthogonal to the inserted rotation shaft. Considering the second resistance contact portion on the one side that is swollen so as to generate a passage resistance at the opposite end of the locking operation member, and the virtual release side rotation region that exceeds the stop position, the opposite of the locking operation member It is possible to adopt a configuration in which a support wall surface that is close to the end is formed, and the rotation tip side of the locking operation member comes into contact with the side surface of the container before the rotation shaft side. .

  As the second hinge, it is possible to employ a structure in which the rotation shaft is inserted into the shaft support portion provided in the container and the container and the locking operation member are connected via the rotation shaft. In such a structure, a portion of the outer side surface of the shaft support portion on the line perpendicular to the inserted rotation shaft is swelled so as to generate a passage resistance of the opposite end of the locking operation member. A second resistance contact portion can be formed. In order to allow the second resistance contact portion on one side to pass through the opposite end of the locking operation member, the opposite end of the locking operation member is considered in the portion on the line when a virtual release side rotation region exceeding the stop position is considered. A support wall surface is formed at a position facing the. For the convenience of providing the shaft support portion in the container, there are cases where it is desired to provide such a support wall surface in such a relationship that the opposing ends of the locking operation member approach when considering a virtual release side rotation region that exceeds the stop position. In this case, the rotation front end side of the locking operation member contacts the side surface of the container before the rotation shaft side, rather than the rotation shaft side of the locking operation member contacts the side surface of the container before the rotation front end side. It is preferable to provide it.

  That is, usually, the locking operation member is removed when the lid is opened, and is often performed in a state where a beverage container having a mouth portion provided on the upper surface is erected. When the locking operation member comes into contact with the container and is in the stop position with the container standing in this way, an object may be unexpectedly hit against the rotation tip side of the locking operation member or the hand may be slid and pushed. Can happen. At this time, since the release-side rotational torque is applied to the rotation front end side of the locking operation member, when the stop position is determined at the contact portion between the rotation shaft side of the locking operation member and the side surface of the container, this becomes a fulcrum. The opposing end of the stop operating member acts as an action point and is pressed against the support wall surface, which may cause damage. If a margin is provided between the supporting wall surface and the opposing end of the locking operation member, the pressing can be avoided. The larger the margin interval is set, the larger the facing interval between the facing end of the locking operation member and the container in a state where the both engaging portions are engaged with each other. Since the facing distance is set at a position that is noticed when the locking operation member is removed, it may be required to be as small as possible in terms of design. Thus, when designing on the basis of the facing interval, a sufficient margin cannot be ensured, and there is a concern about the above-mentioned pressing. If the rotation tip side of the locking operation member comes into contact with the side surface of the container earlier than the rotation shaft side, even if the rotation tip side of the locking operation member is unexpectedly pushed at the stop position, the rotation tip side and the container Therefore, the opposing end of the locking operation member is hardly pressed against the support wall surface of the shaft support portion.

  In addition, the structural requirements regarding the second resistance contact portion are not limited to this invention, and include a lid mounted on the container via a hinge, and a locking operation member mounted on the container via the second hinge, and the container Comprises a beverage container having a mouth on the upper surface, and the engaging operation member is rotated on the engaging side while the lid is in the closed position so that the engaging portion of the engaging operation member is on the other side. Both engagement parts are engaged with each other over the engagement part, and the opening side rotation of the lid is restricted by the engagement, and the stop position of the release side rotation of the locking operation member is in contact with the side surface of the container. It can be applied to containers with lids determined by contact.

  As described above, according to the present invention, in the container with a lid that includes the locking operation member that holds the lid in the closed position, the engagement portion of the locking operation member gets over the mating engagement portion by adopting the above-described configuration. It is possible to reduce the operation force for causing the operation force to increase, and to reduce the increase in the operation force due to the influence of molding errors of the lid and the container.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in FIGS. 1 and 2, the container with a lid according to the embodiment includes a lid 3 attached to the container 1 via a hinge 2, and a container 1 that is one side of the container 1 and the lid 3. A locking operation member 5 mounted via a hinge 4, an elastic body 6 interposed between the lid 3 rotated around the hinge 2 from the open state to the closed position and the container 1, and the hinge 2 When the lid 3 rotated from the opened state to the closed side passes the closed position, the open / close operation member 7 automatically enters the state of restricting the open side rotation beyond the closed position and releases the restriction upon receiving the release operation. And.

  The container 1 is composed of a beverage container having a mouth portion 11 on the upper surface. The container 1 is a portable type having a heat insulating container 12 for containing a beverage, a shoulder cover member 13 attached to the outer periphery of the heat insulating container 12, and a plug 14 of the heat insulating container 12. The mouth portion 11 is formed in the plug 14 and is a cylindrical drinking mouth protruding upward from the shoulder cover member 13. The heat insulating container 12 has a vacuum double heat insulating structure, and can stand on a horizontal plane.

  The shoulder cover member 13 is a synthetic resin injection-molded product. One end of the shoulder cover member 13 is provided with a bearing portion 22 inserted through the horizontal rotation shaft 21 of the hinge 2. The other end of the shoulder cover member 13 is provided with a shaft support portion 42 inserted through the horizontal rotation shaft 41 of the second hinge 4 parallel to the horizontal rotation shaft 21.

  The lid 3 has a cup shape that covers the mouth portion 11, and is attached to the shoulder cover member 13 via the horizontal rotation shaft 21. The lid 3 is an injection molded product of synthetic resin. The lid 3 is rotatable between an open state retracted from above the mouth portion 11 and a closed position covering the mouth portion 11. A torsion spring 23 is incorporated between the lid 3 and the shoulder cover member 13 so as to accumulate a repulsive force that causes the lid 3 to rotate to the open state by the closed side rotation of the lid 3.

  As shown in FIG. 3, the opening / closing operation member 7 is provided at the other end of the shoulder cover member 13 with a restricting position (shown by a solid line in the drawing) around a swing shaft 71 parallel to the horizontal rotation shaft 21 and a restricting release position. (Indicated by a two-dot chain line in the figure). When the lid 3 is rotated from the open state to the closed side around the hinge 2 with the opening / closing operation member 7 in the restricted position, a hook portion 31 protruding from the lower surface of the lid 3 is formed on the upper end side of the opening / closing operation member 7. The cam surface 72 is pushed, the return spring 73 incorporated between the lower end side of the opening / closing operation member 7 and the shoulder cover member 13 is compressed, and the opening / closing operation member 7 is released from the regulation as shown by a two-dot chain line in the figure. Retracted to position. When the hook portion 31 passes through the cam surface 72, the opening / closing operation member 7 is returned to the restricting position by the repulsion of the return spring 73, and the hook portion 31 moves upward to the hook portion 74 of the opening / closing operation member 7 against the torsion spring 23. It is pressed from. Thereby, as shown by a solid line in the figure, the opening / closing operation member 7 is in a state of restricting the opening side rotation beyond the closing position of the lid 3. In this state, when a release operation for pushing the lower end side of the opening / closing operation member 7 against the return spring 73 is received, the hook portion 74 is detached from the hook portion 31 and the lid 3 is automatically opened.

  As shown in FIG. 4, the elastic body 6 includes a rubber packing attached to the lower surface of the lid 3. The elastic body 6 has a knob portion 61 that fits into a shaft portion protruding from the lower surface of the lid 3, and a seal portion 62 that is pressed from above onto the cylindrical protruding wall that forms the mouth portion 11 by the closed side rotation of the lid 3. ing. As a result, as shown by a solid line in the drawing, the opening / closing operation member 7 is interposed between the container 1 and the lid 3 in a restricted state, and the mouth portion 11 is sealed. In this sealed state, the lid 3 is supported on the other end side only by the elastic body 6 with respect to the container 1, and a closed side rotation space of the lid 3 remains between the lid 3 and the container 1. Since the closed side rotation space remains and the elastic body 6 is interposed between the lid 3 and the container 1, the lid 3 can be further rotated on the closed side from the closed position. As shown by a two-dot chain line in the figure, when the lid 3 is further rotated from the closed position to the closed side rotation space, the seal portion 62 of the elastic body 6 increases its bending and opens the mouth portion 11. The sealing with the cylindrical protruding wall to be formed is maintained. The elastic body 6 can also be provided on the upper surface of the container 1 and can be an elastic member having rubber elasticity instead of the rubber packing. When the opening / closing operation member 7 and the torsion spring 23 are omitted, the lid 3 that is rotated on the closed side by the interposition of the elastic body 6 may be temporarily stopped at the closed position with respect to the container 1.

  The locking operation member 5 includes a release-side rotation stop position that contacts the side surface of the container 1, and the engagement portion 32 of the lid 3 that is the other side of the container 1 and the lid 3 in a state where the lid 3 is in the closed position. It can be rotated between rotational positions that can be engaged with each other. When the locking operation member 5 is rotated on the locking side while the lid 3 is in the closed position, the engaging portion 51 of the locking operation member 5 gets over the engaging portion 32 of the lid 3 and both the engaging portions 51 are engaged. 32. Even if the restriction of the opening / closing operation member 7 disappears due to this engagement, the opening side rotation of the lid 3 is restricted.

  More specifically, in the first period of overcoming until the top of the engaging portion 51 of the locking operation member 5 passes the top of the engaging portion 32 of the lid 3, the closing side rotational force applied to the lid 3 as it gets over Thus, the elastic body 6 is compressed, whereby the lid 3 is further rotated from the closed position to the closed side. The lid 3 is rotated to the open side in response to the repulsion of the elastic body 6 in the late stage when the top of the engaging portion 51 passes through the top of the engaging portion 32 and completely passes through the engaging portion 32. Thus, the engaging portions 51 and 32 are engaged with each other. Engagement between the engaging portions 51 and 32 is maintained by the interposition of the elastic body 6.

  The locking operation member 5 covers the opening / closing operation member 7 in a state where the locking operation member 5 is applied as described above. Therefore, the opening / closing operation member 7 cannot be released, and erroneous operation is prevented. Note that the locking operation member 5 may be an appropriate annular body as shown in FIG. 5 if only the preliminary lid locking is intended.

  As shown in FIG. 4, the container 1 and the locking operation member 5 are a resistance contact portion 15 that regulates the release side rotation of the locking operation member 5 from the rotational position where the engagement portions 51 and 32 can be engaged with each other. , 52. The resistance contact portion 15 of the container 1 swells on a portion of the outer surface of the shaft support portion 42 on a line orthogonal to the inserted rotation shaft 41. The resistance contact portion of the locking operation member 5 includes an opposing end 52 that faces in a direction orthogonal to the shaft support portion 42 and the rotation shaft 41. When the opposing end 52 of the locking operation member 5 gets over the resistance contact portion 15, the locking operation member 5 reaches the rotational position. The closed side rotation space provided between the lid 3 and the container 1 in the closed position enables the elastic body 6 to be compressed until the engaging portions 51 and 32 are engaged with each other. For this reason, even if the lid 3 and the container 1 are unexpectedly subjected to external force and the elastic body 6 is compressed even when the lid 3 is restricted to the closed position by the opening / closing operation member 7 and the locking operation member 5, The engagement between the joint portions 51 and 32 can be removed. Even if the engagement portions 51 and 32 are disengaged from each other and the locking operation member 5 tries to cause the release side rotation, the opposed end 52 cannot get over the resistance contact portion 15. For this reason, the locking operation member 5 is maintained at the rotational position. If the unexpected external force disappears and the elastic body 6 repels, the engaging portions 51 and 32 can be engaged again.

  As shown in FIG. 6 (a), the lid 3 is opened with the locking operation member 5 stopped at the rotational position (indicated by a two-dot chain line in the figure) where the engaging portions 51 and 32 can be engaged with each other. , The upper end of the locking operation member 5 is pushed by the tapered surface 33 formed at the lower end of the hook portion 31 of the lid 3 as shown by the solid line in the figure. Thereby, the latching operation member 5 is rotated on the release side, and the latching operation member 5 is retracted from the engaging position as shown in FIG. 6B.

  As indicated by a two-dot chain line in FIG. 1, the stop position of the release side rotation of the locking operation member 5 is determined by contact with the side surface of the container 1. The container 1 and the locking operation member 5 have second resistance contact portions 16 and 52 that restrict locking-side rotation from the stop position. The second resistance contact portion 16 of the container 1 swells on a portion of the outer surface of the shaft support portion 42 on a line orthogonal to the inserted rotation shaft 41. The second resistance contact portion of the locking operation member 5 includes the opposed end 52. When the opposing end 52 of the locking operation member 5 gets over the second resistance contact portion 16, the locking operation member 5 reaches the stop position. When the lip is attached to the mouth 11 and the container 1 is tilted, the beverage is discharged from the mouth 11 through the plug 14 from the heat insulating container 12. When the remaining amount of beverage decreases, the inclination of the container 1 increases. Even if the locking operation member 5 tries to cause the locking side rotation, the opposing end 52 cannot get over the second resistance contact portion 16. For this reason, the locking operation member 5 is maintained at the stop position.

  The opposing end 52 of the locking operation member 5 is non-contact at a portion according to the cylindrical surface between the resistance contact portion 15 and the second resistance contact portion 16 as shown by a one-dot chain line in FIG. It has become a relationship. This is to avoid an unnecessary increase in operating force in the rotation range during this period, and as a result, the locking side rotation and the release side rotation are free. A support wall surface 43 in which the opposing end 52 approaches the portion on the line orthogonal to the rotation shaft 41 of the outer surface of the shaft support portion 42 when the virtual release side rotation region exceeding the stop position of the locking operation member 5 is considered. Is formed. In adopting a design in which the portion of the shaft support portion 42 on the stopper except for the resistance contact portion 15 and the second resistance contact portion 16 has a cylindrical surface as a basic shape, the axis of the cylinder surface and the rotation This is because the shaft 41 has an eccentric relationship that produces the above relationship.

  As shown in FIG. 1, the front surface of the rotation side of the locking operation member 5 bulges more than the rotation shaft 41 side. For this reason, the rotation front end side of the locking operation member 5 comes into contact with the side surface of the container 1 before the rotation shaft 41 side, as indicated by a two-dot chain line in the drawing. Here, when considering the straight line connecting the rotation center C of the rotation shaft 41 and the rotation front end P1 of the locking operation member 5, the rotation front end side of the locking operation member 5 is orthogonal to the straight line at a bisection point. This is the portion on the rotating tip P1 side with respect to the flat surface. Even if the rotation front end side of the locking operation member 5 is unexpectedly pushed at the stop position, the contact portion P between the rotation front end side and the container 1 serves as a fulcrum, so that the opposite end 52 of the locking operation member 5 is the shaft support portion. It becomes difficult to be pressed against the support wall surface 43 of 42.

  The container with a lid according to the embodiment is as described above, and elastic deformation of both the engaging portions 51 and 32 is required to make the engaging portion 51 of the locking operation member 5 get over the engaging portion 32 of the lid 3. Instead, since the compression of the elastic body 6 is used, it is possible to reduce the operating force when getting over the vehicle even when the locking operation member 5 is applied or removed. As a result, deterioration of both the engaging parts 51 and 32 can be prevented. Further, even when the engagement margin between the engaging portions 51 and 31 is increased due to the molding error of the lid 3 or the container 1, the compression of the elastic body 6 reduces the influence of the molding error. For this reason, it can reduce that the operation force at the time of getting over becomes large. When one side on which the locking operation member is mounted is used as a lid, a second hinge is provided on the lid side while the engagement portion of the locking operation member is passed over the engagement portion of the container at the lid closing position. If the elastic body is compressed, the operating force can be similarly reduced.

  Further, in the container with a lid according to the embodiment, since the elastic body 6 made of rubber packing seals the container in a state where the lid 3 is restricted to the closed position by the opening / closing operation member 7, the latching operation member 5 is released. But there is no worry about leaks. Since the elastic body 6 seals the container 1 even when the lid 3 is rotated from the closed position to the closed side, there is no fear of sealing leakage even if the lid 3 is rotated from the closed position by the unexpected external force. Since the rubber packing is used as the elastic body 6, there is no addition of a dedicated part as an elastic body.

  In addition, the container with a lid according to the embodiment is from a rotational position where both the engaging portions 51 and 32 can be engaged with each other by simple means by simply providing the resistance contact portions 15 and 52 on the lid 3 and the locking operation member 5. Since the release-side rotation is restricted, even if the engagement between the two engaging portions is released due to an unexpected external force, the two engaging portions 51 and 32 can be engaged again after the unexpected external force disappears. Therefore, the container with a lid according to the embodiment can improve the re-engagement of both the engaging portions 51 and 32 and can prevent the engagement of the locking operation member 5 from being unexpectedly released.

  Further, even if the lid 3 is rotated from the open state to the closed side while the locking operation member 5 is stopped at the rotational position where the engaging portions 51 and 32 can engage with each other, the lidded container according to the embodiment is Since the latching operation member 5 is pushed by the hook portion 31 of the lid 3 that rotates on the closing side and the latching operation member 5 is rotated on the release side, the collision between the latching operation member 5 and the lid 3 can be released and the damage can be prevented. it can.

  Further, in the container with a lid according to the embodiment, the stop position of the release side rotation of the locking operation member 5 is determined by contact with the side surface of the container 1, so that the locking operation member 5 is farthest from the mouth portion 11. Can be stopped in position. In addition, the locking-side rotation of the locking operation member 5 from the stop position is restricted by the second resistance contact portions 16 and 52, so that even if the container 1 is tilted until it is empty, the locking operation with the beverage or the chin is performed. Contact with the member 5 can be avoided.

  Moreover, even if the rotation front end side of the locking operation member 5 is unexpectedly pushed at the stop position, the contact portion P between the rotation front end side and the container 1 serves as a fulcrum for the lidded container according to the embodiment. Since the opposing end 52 of the member 5 is difficult to be pressed against the support wall surface 43 of the shaft support portion 42, damage near the opposing end 52 can be prevented.
