  Embodiments of the present invention will be described below with reference to the drawings. In the present embodiment, a writing instrument with a container having a lid opening / closing container (lid opening / closing) is described as an example. The writing instrument with a container according to the present embodiment accommodates a printed body (seal) as the contents. In addition, in this specification and drawing, about the component which has the substantially the same function, duplication description is abbreviate | omitted by attaching | subjecting the same code | symbol.

  FIG. 1A is a cross-sectional view showing the lid opening / closing container 1 and the components thereof included in the writing instrument with a container according to the present embodiment. FIG. 1B is a cross-sectional view showing the open / close-lock mechanism 14 of the lid open / close container 1 and its components. In FIG. 1A and FIG. 1B, the lid | cover opening / closing container 1 of the state which the lid | cover closed is shown, and its component. Since the tip cylinder and the writing body included in the writing instrument with a container according to the present embodiment are already known, the illustration and detailed description thereof are omitted.

  The lid opening / closing container 1 of the present embodiment shown in FIGS. 1A and 1B has a rear barrel 10 and one end thereof inserted in the rear barrel 10 so as to be relatively movable, and the other end is a rear barrel. 10, the middle shaft cylinder 20 exposed from 10, a lid 30 disposed so as to be able to open or close the opening 12 a formed on one end surface of the rear shaft cylinder 10, and an opening / closing mechanism (movable body 40, joint 50, etc.) described in detail later ) And a locking mechanism (the front portion of the movable body 40 and the regulating body 60, etc.). In the following description of the present specification, in the extending direction (longitudinal direction) of the central axis of the writing instrument with a container of the present embodiment (hereinafter simply referred to as “axial direction”), the middle shaft cylinder 20 is separated from the rear shaft cylinder 10. The exposed side will be described as the front of the writing instrument with the container (the lid opening / closing container 1), and the lid 30 side will be described as the rear.

  The rear shaft cylinder 10, the middle shaft cylinder 20, and the lid 30 define a storage portion that is an internal space that can store a printing body (not shown) as the contents in the present embodiment. The rear barrel 10 formed in a substantially cylindrical shape constitutes the second half of the writing instrument with a container according to the present embodiment, and constitutes the outer peripheral wall of the lid opening / closing container 1. The rear end portion of the middle shaft cylinder 20 has a bottom plate and constitutes a bottom wall (front wall) of the housing portion. The bottom plate only needs to be disposed on the side opposite to the end where the opening of the lid opening / closing container 1 is disposed. In other embodiments, the tip of the central barrel may have the bottom plate. The lid | cover 30 comprises the upper wall (rear wall) which can open and close an accommodating part. When the middle barrel 20 moves rearward relative to the rear barrel 10 and is inserted deeper into the rear barrel 10, the opening / closing mechanism of the lid opening / closing container 1 opens the lid 30 and the bottom wall of the housing portion. The rear end portion of the middle shaft cylinder 20 that constitutes A approaches the opening 12a at the rear end portion of the lid opening / closing container 1. The print body can be fixed to the bottom wall of the housing portion by fitting the front end portion of the print body into the fit portion 22 disposed at the rear end portion of the central cylinder 20. For this reason, the user can write with the writing body provided in the writing instrument with a container according to the present embodiment, and the rear end portion of the printing body from the opening 12a of the rear end portion of the lid opening / closing container 1 with the lid 30 opened. Can be stamped by protruding.

  The rear barrel 10 and the middle barrel 20 are urged to be separated from each other in the front-rear direction by a return spring 90 that is an elastic body. When the rear shaft cylinder 10 and the middle shaft cylinder 20 move so as to be relatively separated from each other in the front-rear direction by the urging force of the return spring 90, the rear end portion of the middle shaft cylinder 20 constituting the bottom wall of the housing portion is the lid opening / closing container 1. The printing body is housed in the housing portion apart from the opening 12a at the rear end portion, and the opening / closing mechanism of the lid opening / closing container 1 closes the lid 30. For this reason, since the user can accommodate the printing body fixed to the bottom wall of the housing portion in the housing portion and close the opening 12a with the lid 30, it is possible to prevent unintended contact with the printing body.

(Opening / closing mechanism)
With reference to FIG. 1A and FIG. 1B, the opening / closing mechanism of the lid | cover 30 which the lid | cover opening / closing container 1 has is demonstrated. The opening / closing mechanism of the lid 30 has a movable body 40 and a joint 50, and converts relative movement between the rear barrel 10 and the middle barrel 20 into an opening / closing motion of the lid 30. The base portion 32 of the lid 30 is pivotally supported on the rear barrel 10 by a first pivot 82 arranged so as to extend in a direction that forms an angle of 90 degrees with respect to the axial direction. Further, as will be described in detail later, the movable body 40 is fixed to the middle shaft cylinder 20, and the rear end portion of the movable body 40 and the front end portion of the joint 50 extend in a direction that forms an angle of 90 degrees with respect to the axial direction. The third pivots 86 are arranged so as to be rotatable with respect to each other. Further, the rear end portion of the joint 50 is pivotally supported on the base portion 32 of the lid 30 by a second pivot 84 disposed so as to extend in a direction that forms an angle of 90 degrees with respect to the axial direction. .

In the configuration of the present embodiment, when the middle shaft cylinder 20 is inserted deeper into the rear shaft cylinder 10 against the urging force of the return spring 90, the middle shaft cylinder 20, the movable body 40, and the joint 50 are connected to the rear side of the lid opening / closing container 1. It moves so as to approach the opening 12a at the end. At this time, the opening / closing mechanism of the lid opening / closing container 1 can be opened by pushing the lid 30 backward. The angle θ ₁ formed by the central axis of the joint 50 shown in FIG. 1A and the central axis of the lid opening / closing container 1 (the moving direction of the movable body 40) will be described in detail later.

  With reference to FIG. 2A and FIG. 2B, the lid | cover opening / closing container 1 of the state which the lid | cover opened is demonstrated. FIG. 2A is a cross-sectional view showing the lid opening / closing container 1 and its components in a state where the lid is opened. FIG. 2B is a cross-sectional view showing the open / close-lock mechanism 14 of the lid open / close container 1 with its lid open and its components.

The lid opening / closing container 1 includes a joint 50 pivotally supported by the third pivot 86 with respect to the movable body 40 and pivotally supported by the second pivot 84 with respect to the base 32 of the lid 30. Can be opened by swinging the lid 30 larger than before. In the state where the lid 30 is opened, the joint 50 can rotate to the rotation angle θ ₂ as illustrated with respect to the movable body 40 and the central axis of the lid opening / closing container 1 with the third pivot 86 as the rotational axis. In the lid opening / closing container 1 of the present embodiment, the lid 30 can be opened by rotating the joint 50 to an angle at which θ ₂ is about 70 degrees. At least by the rotation angle θ _{2 of the} joint 50, the lid 30 can be swung open more than before, so that the user can attach the container of the present embodiment without causing the lid 30 to interfere with the object to be stamped. A printed body protruding from the rear end of the writing instrument can be suitably used. In the present embodiment, the lid 30 can be swung open at an opening / closing angle of about 160 degrees from the open state to the closed state.

(Movable body 40)
The movable body 40 will be described in detail with reference to FIGS. 3A to 3B and 1A. FIG. 3A is a diagram showing the movable body 40 as seen from the side surface of the lid opening / closing container 1. FIG. 3B is a view showing the movable body 40 taken along line AA in FIG. 3A and viewed from the outer diameter direction of the lid opening / closing container 1. The external shape of the movable body 40 before being cut along the AA line is indicated by a two-dot chain line. The movable body 40 is formed in a rod shape, and is disposed so as to extend in the axial direction of the open / close-lock mechanism unit 14. Two support plates 42 are formed on the rear end portion of the movable body 40 so as to face each other so that the front end portion of the joint 50 can be disposed therebetween. Each support plate 42 has an insertion hole 422 that pivotally supports the third pivot 86.

  A fitting groove 46 is formed at a substantially central position in the axial direction of the movable body 40. When the fitting groove 46 is fitted into a fitting projection 24 (see FIG. 8) of the middle shaft cylinder 20 described in detail later, the movable body 40 is fixed so as not to move relative to the middle shaft cylinder 20. The movable body 40 fixed to the middle shaft cylinder 20 moves in the axial direction of the lid opening / closing container 1 together with the middle shaft cylinder 20 so as to approach and separate from the opening 12a of the lid opening / closing container 1. The moving direction of the movable body 40 may be a direction that can approach and separate from the opening 12a. In another embodiment, the movable body 40 has a predetermined direction with respect to the axial direction of the lid opening / closing container 1. It is good also as what moves back and forth in the moving direction which has an inclination angle, and approaches and separates with respect to the opening 12a. For example, as the movable body moves backward, the reciprocating direction of the movable body is inclined with respect to the axial direction of the lid opening / closing container by a predetermined inclination angle determined so as to go outward in the radial direction of the lid opening / closing container. Also good. In this case, the opening angle of the lid can be set to a larger opening angle.

  The front end portion of the movable body 40 constitutes an opening / closing / locking mechanism portion 14 of the lid opening / closing container 1 together with a regulating body 60 (see FIG. 9A) described in detail later. An engaging portion 44 having an internal space 44 c is formed at the front end portion of the movable body 40. The internal space 44c is defined by a wall portion 44b having a communication port 442 (as a passage port) into which the insertion portion 62 (see FIG. 9A) of the restriction body 60 can be inserted, and two wall portions 44a. Further, a locking groove 444 in which a locking claw 624 (see FIG. 9A) formed in the insertion portion 62 of the restricting body 60 described in detail later can be locked is formed on the inner space 44c side of the wall portion 44b. . The locking mechanism of the lid opening / closing container 1 will be described in detail later.

(Fitting 50)
The joint 50 will be described in detail with reference to FIGS. 4A to 4B and 1A. FIG. 4A is a view showing the joint 50 as seen from the side of the lid opening / closing container 1. 4B is a view showing the joint 50 as seen from the outer diameter direction of the lid opening / closing container 1 by cutting along the line AA in FIG. 4A. The joint 50 is formed in a rod shape having a semicircular side surface shape in which the front end portion and the rear end portion are round in the rotational operation direction of the joint 50. Arranged between. An insertion hole 51 is formed in the rear end portion of the joint 50, and a second pivot 84 inserted into the insertion hole 51 is pivotally supported. The joint 50 is rotatably connected to the base 32 of the lid 30 via the second pivot 84. An insertion hole 52 is formed in the front end portion of the joint 50, and a third pivot 86 inserted into the insertion hole 52 is pivotally supported. The joint 50 is rotatably connected to the rear end portion of the movable body 40 via the third pivot 86. The joint 50 may be pivotally connected to the base 32 of the lid 30 and the movable body 40. In other embodiments, for example, the joint is connected to the base of the lid and the movable body via a ball joint. It is good also as what connects so that rotation is possible. In this case, the joint can be pivotally connected to the base of the lid and the movable body via the ball joint, so that the operating resistance generated when the lid opening / closing mechanism is actuated can be reduced.

The central axis of the joint 50 passing through the center of the insertion hole 51 (second pivot 84) and the center of the insertion hole 52 (third pivot 86) of the joint 50 of the present embodiment is It arrange | positions so that it may have predetermined | prescribed angle (theta) ₁ with respect to the center axis line of the lid | cover opening / closing container 1 (and movable body 40) so that the rocking | fluctuation angle of the 2nd pivot 84 around the 1 pivot 82 may be increased. In other words, the central axis of the joint 50 is arranged so as to have a predetermined angle θ ₁ with respect to the moving direction of the movable body 40, not on the moving direction of the movable body 40 in a state where the lid 30 is closed. Since the joint 50 is pivotally supported with respect to the movable body 40 by the third pivot 86, the central axis of the joint 50 is parallel to the moving direction of the movable body 40 when the lid 30 is closed. Instead, it can have a predetermined angle θ ₁ as described above.

  With this configuration, when the lid 30 swings about the first pivot 82 as the rotation axis, the stroke length of the second pivot 84 in the circumferential direction in which the second pivot 84 can swing around the first pivot 82 is configured. The length can be further increased. Therefore, the rotation angle at which the lid 30 can swing around the first pivot 82 is further increased from the state in which the lid 30 is closed (see FIG. 1A) to the state in which the lid 30 is opened (see FIG. 2A). it can.

The predetermined angle θ ₁ efficiently pushes the lid 30 backward by the joint 50 pivotally supported on the movable body 40 by the third pivot 86 against the operating resistance generated when the lid 30 is opened. Thus, it is preferable to provide the lid 30 at an angle at which the lid 30 can be opened. For example, the predetermined angle θ ₁ is preferably set at an acute angle smaller than 90 degrees, more preferably, the predetermined angle θ ₁ is preferably set at an acute angle smaller than 60 degrees, and most preferably the predetermined angle θ. ₁ is preferably provided at an acute angle smaller than 30 degrees. In the present embodiment, the predetermined angle θ ₁ is provided at an angle of about 10 degrees.

(Lid 30)
The lid 30 will be described in detail with reference to FIGS. 5A to 5B and 1A. FIG. 5A is a view showing the lid 30 as seen from the direction of the outer periphery where the opening / closing-lock mechanism 14 of the lid opening / closing container 1 is arranged. FIG. 5B is a diagram showing the lid 30 cut along line BB in FIG. 5A and viewed from the normal direction of the cut surface (direction BB in FIG. 5A). The lid 30 includes a lid plate portion 34 that can close the opening 12 a of the lid opening / closing container 1, and a base portion 32 that connects the lid plate portion 34 to the opening / closing-locking mechanism portion 14 of the lid opening / closing container 1. The cross-sectional shape of the lid plate portion 34 is formed in a substantially arch shape that protrudes toward the rear end side and is curved so that the structural strength of the lid plate portion 34 and the capacity of the lid opening / closing container 1 can be increased.

  The base 32 of the lid 30 is formed with an insertion hole 32a into which the first pivot 82 is inserted. The insertion hole 32a pivotally supports the first pivot 82 so as to be rotatable. The first pivot 82 is inserted into an insertion hole 144 (see FIG. 7A) formed in the rear barrel 10 which will be described in detail later, and is pivotally supported. Therefore, the lid 30 is pivotally supported with respect to the rear barrel 10 with the first pivot 82 as a rotation axis, and has an opening 12a formed on the rear end surface of the rear barrel 10 of the lid opening / closing container 1. Can be opened and closed.

  An insertion hole 32b into which the second pivot 84 is inserted is formed at a position separated from the insertion hole 32a of the base portion 32 of the lid 30 by a predetermined distance L. The insertion hole 32b pivotally supports the second pivot shaft 84. As described above, the second pivot 84 is pivotally supported by the rear end portion of the joint 50 so as to be rotatable. For this reason, the lid | cover 30 is connected with respect to the rear-end part of the coupling 50 so that rotation is possible. A concave portion that can receive the rear end portion of the joint 50 is formed on the front end side of the base portion 32 of the lid 30. With the rear end portion of the joint 50 received in the recess of the base portion 32, the second pivot 84 is inserted through the insertion hole 32b of the lid portion 30 and the insertion hole 51 (see FIG. 4A) of the joint 50. Thereby, the cover part 30 and the coupling 50 are connected so that rotation is possible.

  A predetermined distance L between the central axis of the insertion hole 32 a that supports the first pivot 82 and the central axis of the insertion hole 32 b that supports the second pivot 84 acts as a moment arm for opening and closing the lid 30. If the length L of the moment arm is increased, the lid 30 can be efficiently opened and closed with a smaller operating force. Further, when the lid 30 is opened, it acts on the lid 30 around the first pivot 82 (clockwise in FIG. 1A) rather than the rotational moment (clockwise in FIG. 1A) acting on the joint 50 around the third pivot 86. It is preferable to arrange the insertion hole 32a and the insertion hole 32b apart by a predetermined distance L so that the rotational moment becomes larger in order to increase the efficiency of the operation of the opening / closing mechanism.

In particular, in the present embodiment, as described above, when the joint 50 starts to open the lid 30, its central axis is a predetermined angle with respect to the central axis of the lid opening / closing container 1 (movement direction of the movable body 40). It presses the lid 30 on the rear end side (rear in the moving direction of the movable body 40) in a state having a theta _1. At this time, before the lid 30 starts to rotate forward around the first pivot 82 (clockwise rotation in FIG. 1A), it opens and closes when the joint 50 rotates backward (clockwise rotation in FIG. 1A) around the third pivot 86. The operating efficiency of the mechanism may be reduced. When the lid 30 starts to be opened, it is possible to prevent the operating efficiency of the opening / closing mechanism from being lowered by preventing the joint 50 from starting reverse rotation around the third pivot 86. Therefore, in order to increase the opening / closing angle of the lid 30, the central axis of the joint 50 has a predetermined angle θ ₁ with respect to the moving direction of the movable body 40 as described above when the lid 30 is closed. Also when comprised, the lid 30 can be efficiently pushed and opened rearward along the moving direction of the movable body 40 by the joint 50.

The rear barrel 10 is formed in a substantially hollow cylindrical shape having openings 12a and 12b at both ends. Further, the rear barrel 10 is formed with a projecting portion constituting the outer wall of the opening / closing / locking mechanism portion 14 extending along the axial direction so as to protrude radially outward. Further, a recess 16 is formed on the outer peripheral surface at the substantially center in the axial direction of the rear barrel 10 over the protrusion of the opening / closing / locking mechanism portion 14. A button 70 (see FIG. 1B), which will be described in detail later, is disposed in the recess 16. In the recess 16, a through hole 162 and a support hole 164, which is a stop hole having a smaller diameter than the through hole, are formed so as to be aligned along the axial direction. A long leg portion 72 (see FIG. 1B) and a short leg portion 74 (see FIG. 1B) of the button 70, which will be described in detail later, are fitted into the through hole 162 and the support hole 164, respectively.

FIG. A support plate 142 for supporting the lid 30 is formed at the rear end of the rear barrel 10. The support plate 142 is formed with an insertion hole 144 into which the first pivot 82 for pivotally supporting the lid 30 and the rear barrel 10 can be inserted. Two support plates 142 are formed on the rear barrel 10 so as to face each other, and the base 32 of the lid 30 is arranged between the two support plates 142 facing each other.

And the rocking of the lid 30 can be locked.

(Regulator 60)
The regulating body 60 is disposed in front of the movable body 40 in the axial direction (see FIG. 1B). An elastic piece 64 that is elastically deformable in a direction (an arrow C direction) having an angle of 90 degrees with respect to the axial direction of the lid opening / closing container 1 is formed at the front portion of the regulating body 60 by an external force applied by the user. When the user presses the button 70 (see FIG. 1B) of the lid opening / closing container 1 described in detail later in a direction having an angle of 90 degrees with respect to the axial direction of the lid opening / closing container 1, the elastic piece 64 of the regulating body 60 is elastically deformed. Then, the regulating body 60 moves so as to be restored in a direction having an angle of 90 degrees with respect to the axial direction of the lid opening / closing container 1.

  An insertion hole 66 (see FIG. 9B) is formed at substantially the center of the restricting body 60 in the axial direction. By inserting the long leg portion 72 (see FIG. 1B) of the button 70 into the insertion hole 66, the restricting body 60 is fixed so that it cannot be moved relative to the rear barrel 10 in the axial direction. .

  An insertion portion 62 that can be inserted into the internal space 44c (see FIG. 1B) of the movable body 40 is formed at the rear portion of the regulating body 60. An inclined portion 622 is formed at the rear end portion of the insertion portion 62 so as to protrude at a predetermined angle (about 20 ° in the present embodiment) with respect to the central axis of the regulating body 60 and the lid opening / closing container 1. . In addition, the front end portion of the insertion portion 62 is a protrusion protruding in a direction having an angle of 90 degrees with respect to the central axis of the regulating body 60 (and the lid opening / closing container 1) (direction opposite to the arrow C). A locking claw 624 is formed.

  In a state where the lid 30 is closed (see FIG. 1B), the insertion portion 62 of the regulating body 60 passes through the communication port (passage port) 442 (see FIG. 3B) formed at the distal end portion of the movable body 40. It is inserted into the space 44c. The locking claw 624 of the restricting body 60 contacts the front wall portion 44b in which a locking groove 444 (see FIG. 3B) is formed from the inner space 44c side of the movable body 40. The locking claw 624 of the regulating body 60 fixed to the rear barrel 10 locks the movable body 40 fixed to the middle barrel 20 so that the movable body 40 is directed in the axial direction toward the opening 12 a of the rear barrel 10.
