Description

Technical Field

[0001] The present disclosure relates to an injection operation instrument to which an injection container capable of injecting a liquid is attached.

Background Art

[0002] An injection container for injecting a liquid into the nasal cavity, oral cavity, etc. has been conventionally known. The injection container includes a bottomed cylindrical container body and a cylindrical nozzle attached to the tip of the container body so as to be able to advance and retreat. When the nozzle is pushed into the container body, the liquid stored in the container body is injected from the nozzle.

[0003] In such an injection container, when pushing the nozzle into the container body, there is a problem that the position of the nozzle with respect to the nose or mouth is displaced, and the liquid is not injected into the desired site. In response to this problem, for example, an injection operation instrument (injector) described in Patent Document 1 has been proposed.

[0004] The injection operation instrument is attached to an injection container and used, and includes an operating portion (drive lever) extending in the extending direction of the injection container. When the operating portion is pushed in a direction intersecting the extending direction, the container body is pushed into the nozzle, and the liquid is injected from the nozzle.

Mode for Carrying Out the Invention

[0011] <Knowledge on which the present disclosure is based> The injection operation instrument described in Patent Document 1 includes a case that houses an injection container, an operating portion attached to the case, and a rotating member (link member) connected to the operating portion. The rotating member is configured to be rotatable within the case while the operating portion is pushed. When the operating portion is pushed by a user, the rotating member rotates and presses the injection container against the nozzle. Specifically, the rotating member contacts a flange provided on the container body and pushes the container body upward toward the nozzle.

[0012] When replacing the injection container, it is necessary to place the injection container in the correct position relative to the rotating member. For example, in the injection operation instrument of Patent Document 1, it is necessary to place the injection container so that the rotating member contacts the flange in the correct orientation. If the injection container is placed in an incorrect position relative to the rotating member, the mode of injection and the injection amount may become inappropriate, or the injection container or the injection operation instrument may be damaged during injection.

[0013] In addition, in order to correctly place the injection container, it may be considered to attach the injection container while holding the rotating member with a finger. However, the operation of attaching the injection container while holding the rotating member is not only complicated but may even be difficult for the elderly or those with limited manual dexterity.

[0014] Therefore, as a result of intensive studies to facilitate the replacement of the injection container, the present inventors have found a configuration of an injection operation instrument provided with a biasing portion that biases the rotating member. The biasing portion biases the rotating member in a non-mounted state where the injection container is not attached, and maintains the rotating member at an acceptance position where the injection container can be received. According to this configuration, the rotating member is maintained at the acceptance position without being pressed by a finger in the non-mounted state, so that it becomes easier to correctly place the injection container relative to the rotating member. Therefore, an injection operation instrument that facilitates the replacement of the injection container is provided. Based on this new finding, the present inventors have arrived at the following disclosure.

[0015] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the following description, terms indicating a specific direction or position (for example, terms including "up" and "down") are used as necessary, but the use of these terms is for facilitating the understanding of the present disclosure with reference to the drawings, and the technical scope of the present disclosure is not limited by the meanings of these terms. Further, the following description is merely exemplary in nature and is not intended to limit the present disclosure, its applications, or its uses.

[0016] For illustrative purposes, the drawings show an XYZ Cartesian coordinate system, which is provided to facilitate understanding of this disclosure and does not limit it.

[0017] <Embodiment> The spraying device according to an embodiment of this disclosure will be described with reference to Figures 1 to 12. The spraying device 1 shown in Figure 1 is detachably fitted with a spraying container 100 capable of spraying liquid. As shown in Figure 2, the spraying container 100 has a bottomed cylindrical container body 110 for containing liquid and a cylindrical nozzle 120 attached to the container body 110 so as to be able to move back and forth. The container body 110 and the nozzle 120 each extend along the Z direction. The Z direction corresponds to the "extension direction of the spraying container" in this disclosure. In this embodiment, the spraying container 100 is substantially cylindrical and is formed rotationally symmetrically about a virtual central axis extending in the Z direction. In the following description, for convenience of explanation, assuming the orientation of the spraying device 1 and spraying container 100 shown in Figure 2, the positive direction of the Z axis may be referred to as up, and the negative direction of the Z axis may be referred to as down.

[0018] The container body 110 has a bottomed cylindrical storage section 111 with a storage chamber R1 for containing liquid, and a nozzle connection section 112 connected to the storage section 111. For example, the storage section 111 has screw threads near the opening, and the nozzle connection section 112 has screw grooves at the end opposite the storage section 111. The storage section 111 and the nozzle connection section 112 are connected by the engagement of these screw threads and screw grooves.

[0019] The housing portion 111 has a container flange 113 that protrudes outward in the radial direction with respect to the central axis. In this embodiment, the container flange 113 is provided such that the screw threads are located between it and the opening in the Z direction. The container flange 113 has a surface facing the nozzle connection portion 112 in the Z direction (the upward surface in Figure 2) and a contact surface 113a which is the opposite surface.

[0020] The nozzle 120 is connected to the tip of the nozzle connection portion 112 such that the nozzle connection portion 112 is sandwiched between the nozzle 120 and the housing portion 111 in the Z direction. In other words, the nozzle 120 is connected to the tip of the container body 110 (the upper end in Figure 2). The nozzle connection portion 112 provides fluid communication between the housing chamber R1 and the nozzle 120.

[0021] The tip of the nozzle 120 is provided with an injection opening 121 for spraying liquid. The nozzle 120 has a known pump mechanism for spraying the liquid in the containment chamber R1 through the injection opening 121. When the nozzle 120 is pushed in the Z direction relative to the tip of the nozzle connection part 112, the pump mechanism is activated and the liquid in the containment chamber R1 is sprayed through the injection opening 121. The manner in which the liquid is sprayed may be in the form of a jet or a mist, depending on the dimensions, number, shape, etc., of the injection opening 121.

[0022] The nozzle 120 has a nozzle flange 122 that protrudes outward in the radial direction with respect to the central axis. When using the spray container 100 alone, for example, the liquid can be sprayed by placing the index and middle fingers on the nozzle flange 122 and pushing the housing 111 toward the nozzle 120 with the thumb.

[0023] As shown in Figure 1 or Figure 2, the spraying device 1 comprises a cylindrical case 2 that covers the side wall of the spraying container 100 and a rotating member 6 provided inside the case 2. In this embodiment, the case 2 is substantially cylindrical. In the example shown in Figure 2, the case 2 covers a portion of the side wall of the housing portion 111, a portion of the side wall of the nozzle connection portion 112, and a portion of the side wall of the nozzle 120. The case 2 is made of, for example, resin.

[0024] As shown in Figure 1 or Figure 2, the case 2 has a cylindrical side wall portion 21, a case tip portion 22, and a case base portion 23 which is the end opposite to the case tip portion 22. As shown in Figure 2, the side wall portion 21 has an inner wall surface 21a.

[0025] As shown in Figures 2 and 3, the tip portion 22 of the case is provided with a tip opening 24 for the nozzle 120 to pass through when the spray container 100 is attached. Therefore, the tip portion 22 of the case is adjacent to the nozzle 120 in a direction intersecting the Z direction (for example, the X direction or the Y direction). In this embodiment, the tip opening 24 is substantially circular in a plan view from the Z direction.

[0026] As shown in Figures 2 and 4, the base end 23 of the case is provided with a base end opening 25 into which the container body 110 can be inserted. As a result, as shown in Figures 1 and 2, the spray container 100 can be attached to the spray operating device 1 with the container body 110 extending to the outside of the case 2 through the base end opening 25. The base end opening 25 corresponds to the "container opening" in this disclosure. In this embodiment, the base end opening 25 is substantially circular when viewed from the bottom in the Z direction.

[0027] As shown in Figure 2, the tip portion 22 of the case is provided with a ring-shaped groove 26 that is recessed outward in the radial direction of the case 2. When installed, the nozzle flange 122 is inserted into the groove 26. This restricts the movement of the nozzle 120 in the Z direction relative to the case 2.

[0028] As shown in Figure 1, a bottomed cylindrical cap 7 can be attached to the tip 22 of the case when spraying is not taking place. This covers the portion of the nozzle 120 located outside the case 2 with the cap 7. As shown in Figure 5, the cap 7 has a stopper 71 that protrudes away from the bottom.

[0029] As shown in Figure 3, the tip portion 22 of the case is provided with two stopper insertion holes 27 that are positioned to sandwich the tip opening 24 in a plan view from the Z direction. As shown in Figure 1, when the cap 7 is connected to the tip portion 22 of the case, the stopper 71 is positioned inside the case 2 via the stopper insertion holes 27.

[0030] As shown in Figure 5, the case 2 has a first member 3 and a second member 4 that are divided along the X direction. The first member 3 has a pair of mounting tabs 31 that project in the Y direction toward the second member 4. The tip of each mounting tab 31 is provided with a projection 311 that protrudes away from the other mounting tab 31 in the X direction.

[0031] The second member 4 is provided with a pair of mounting slits 41 corresponding to a pair of protrusions 311. Figure 5 shows only one of the pair of mounting slits 41. The first member 3 and the second member 4 are attached to each other by inserting the protrusions 311 into the mounting slits 41 due to the elasticity of the mounting tab 31.

[0032] As shown in Figure 8, the first member 3 is provided with two bearing portions 32 on the inner wall surface 21a for rotatably attaching the rotating member 6 to the case 2. The bearing portion 32 has a biasing portion 321 that protrudes from the inner wall surface 21a and a shaft holding portion 322 that protrudes from the inner wall surface 21a at a position aligned with the biasing portion 321 along the Z direction. In this embodiment, the biasing portion 321 is located above the shaft holding portion 322. The tip of the biasing portion 321 and the tip of the shaft holding portion 322 are bent toward each other.

[0033] In this embodiment, the biasing portion 321 and the shaft holding portion 322 are formed integrally with the case 2. Furthermore, the shaft holding portion 322 is configured similarly to the biasing portion 321, except for the direction of bending of each tip. For example, the biasing portion 321 and the shaft holding portion 322 have the same or substantially the same modulus of elasticity.

[0034] As shown in Figure 5, the rotating member 6 is rotatably mounted on the two bearing portions 32. In the following description of the rotating member 6, we will assume that the rotating member 6 is mounted on the case 2 (see Figure 5) and will use terms indicating directions such as the X, Y, and Z directions. As shown in Figure 9, the rotating member 6 has a beam portion 61 and a rotating shaft 62 attached to the beam portion 61. As shown in Figures 5, 9, and 10, the rotating member 6 is formed symmetrically with respect to the YZ plane that includes the center of the rotating shaft 62 in the X direction.

[0035] The rotating shaft 62 extends in the X direction when the rotating member 6 is mounted on the case 2 and is supported by two bearing portions 32 (see Figure 8). Specifically, as shown in Figure 11, the rotating shaft 62 is held between a biasing portion 321 and a shaft holding portion 322 in each bearing portion 32. The biasing portion 321 and the shaft holding portion 322 are bent at their respective ends, which prevents the rotating shaft 62 from coming off the bearing portion 32.

[0036] As shown in Figure 11, the rotating shaft 62 has a first dimension S1 in the Z direction and a second dimension S2 in the direction intersecting the first dimension S1 (for example, the Y direction) in a cross section that intersects the extending direction of the rotating shaft 62. Here, the first dimension S1 and the second dimension S2 are measured with reference to the state in which the rotating member 6 is in the receiving position (described later). In this embodiment, the cross-sectional shape of the rotating shaft 62 is a rectangular shape with the shorter side curved.

[0037] The second dimension S2 is larger than the first dimension S1 and is larger than the distance D1 in the Z direction between the biasing portion 321 and the shaft holding portion 322. The distance D1 is measured, for example, in the portion of the biasing portion 321 and the shaft holding portion 322 excluding the tip.

[0038] As shown in Figure 5, the beam portion 61 extends along the inner wall surface 21a in a direction intersecting the Z direction. In this embodiment, the beam portion 61 has a substantially semicircular shape in a plan view from the Z direction.

[0039] As shown in Figure 10, the rotating member 6 further has a pair of hook portions 63 extending from the beam portion 61 toward the case base portion 23 in the Z direction. In other words, the hook portions 63 extend from the beam portion 61 toward the negative Z direction. The pair of hook portions 63 are arranged to face each other in the X direction. Each hook portion 63 has a tip portion 631 that is bent toward the other hook portion 63. The tip portion 631 has a contact surface 631a that faces the case tip portion 22 in the Z direction and contacts the container flange 113.

[0040] As shown in Figures 9 and 10, a pair of column portions 64 extending in the Z direction are provided at both ends of the beam portion 61. The dimensions of the column portions 64 in the Z direction are larger than those of the beam portion 61 in the Z direction. As shown in Figure 10, the column portions 64 are provided with contact grooves 65 that extend along the Z direction and are recessed toward the rotation axis 62 along the Y direction. In other words, the contact grooves 65 are recessed in the positive direction of the Y axis. The contact grooves 65 come into contact with the tip portion 531 (described later) of the operating portion 5 when the first member 3 and the second member 4 are assembled.

[0041] The contact groove 65 has a first end 651 closer to the case base end 23 in the Z direction and a second end 652 closer to the case tip end 22. In this embodiment, the first end 651 is located at the edge of the column 64 and is open. The second end 652 is provided with a wall 66 extending in the negative direction of the Y axis from the bottom surface of the contact groove 65. The second end 652 is closed by the wall 66.

[0042] The rotating member 6 can rotate between a receiving position in which the container body 110 can be received (see Figures 2 and 6) and a spraying position in which the container body 110 is pushed against the nozzle 120 (see Figure 7).

[0043] As shown in Figure 2, when the rotating member 6 is in the receiving position, the spray container 100 can be attached to the first member 3 in the Y direction such that the container flange 113 faces the contact surface 631a of the hook portion 63.

[0044] The operation of the biasing unit 321 and the shaft holding unit 322 will be explained with reference to Figures 11 and 12. Figure 11 shows the state in which the rotating member 6 is in the receiving position. Figure 12 shows the state in which the rotating member 6 is in a position other than the receiving position (for example, the injection position).

[0045] As shown in Figure 11, when the rotating member 6 is in the receiving position, the biasing portion 321 and the shaft holding portion 322 are in the shape with the least deflection among the shapes that the biasing portion 321 and the shaft holding portion 322 can take as the rotating member 6 rotates. In this embodiment, both the biasing portion 321 and the shaft holding portion 322 are in contact with the rotating shaft 62, but either the biasing portion 321 or the shaft holding portion 322 does not need to be in contact with the rotating shaft 62.

[0046] As shown in Figure 12, when the rotating member 6 rotates to a position other than the receiving position, the gap between the biasing portion 321 and the shaft holding portion 322 is widened by the rotating shaft 62. At this time, the biasing portion 321 is pushed by the rotating shaft 62 and bends more than when the rotating member 6 is in the receiving position. In this embodiment, since the shaft holding portion 322 is configured similarly to the biasing portion 321, the shaft holding portion 322 also bends more than when the rotating member 6 is in the receiving position.

[0047] On the other hand, the biasing portion 321 biases the rotating shaft 62 by an elastic force that tries to return to a state of less deflection. As a result, when the injection container 100 is not attached and no external force is applied to the rotating member 6, the rotating member 6 is maintained in the receiving position shown in Figure 11. In this embodiment, the shaft holding portion 322 also biases the rotating shaft 62 in the same way as the biasing portion 321.

[0048] As shown in Figure 1, in the second member 4, the side wall portion 21 is provided with an opening 42 for providing an operating part 5, which will be described later. In this embodiment, the opening 42 is a substantially rectangular shape when viewed from the Y direction, having a short side extending in the X direction and a long side extending in the Z direction.

[0049] The second member 4 further has an actuation part 5 that extends along the Z direction and covers at least a portion of the opening 42. The actuation part 5 is operated by the user to rotate the rotating member 6 from the receiving position to the ejection position.

[0050] The operating unit 5 includes a first hinge 511 provided on the edge of the opening 42 extending in the X direction, and an operating unit 52 connected to the second member 4 via the first hinge 511.

[0051] The operating section 52 extends from the first hinge 511 in the Z direction toward the case tip 22. In other words, the operating section 52 extends from the first hinge 511 in the positive Z direction. In this embodiment, the operating section 52 is formed in a flat plate shape and, in plan view, is a substantially rectangular shape with a short side extending in the X direction and a long side extending in the Z direction. As shown in Figure 1, the operating section 52 is inclined toward the opening 42 as it approaches the case tip 22 along the Z direction. The operating section 52 is pushed in the Y direction, for example by the user's thumb, causing it to rotate around the first hinge 511 toward the spray container 100, as shown in Figure 7. Note that in Figure 7, the positions of the operating section 5 and the bottom of the housing section 111 in the unoperated state (see Figure 6) are shown by dashed lines.

[0052] As shown in Figures 1 and 6, the operating part 5 further includes a second hinge 512 provided on the edge of the operating part 52 and a connecting part 53 extending from the second hinge 512 toward the rotating member 6. The second hinge 512 is provided on the short side portion of the operating part 52 in a plan view that is not connected to the first hinge 511. The second hinge 512 extends in the X direction. In this embodiment, the first hinge 511 and the second hinge 512 extend parallel to each other.

[0053] As shown in Figures 1 and 5, the connecting portion 53 has a bifurcated shape that branches as it approaches the rotating member 6. As shown in Figures 1, 5, and 6, the connecting portion 53 has two tip portions 531 that are inserted into the contact groove 65 of the rotating member 6 and come into contact with the rotating member 6. The tip portions 531 correspond to the "contact portion" in this disclosure.

[0054] As shown in Figure 6, two angles A1 and A2 are formed between the operating section 52 and the connecting section 53, centered on the second hinge 512. Angle A1 is formed by the opposing surface of the operating section 5 that faces the injection container 100 in the Y direction. Angle A2 is formed by the surface of the operating section 5 opposite to the said opposing surface.

[0055] In this embodiment, the first hinge 511, the operating portion 52, the second hinge 512, and the connecting portion 53 are integrally formed with the second member 4. In this case, the first hinge 511 and the second hinge 512 are formed thinner than the portions connected by each hinge, as shown in Figure 6.

[0056] As shown in Figure 1, the two edges of the opening 42 extending in the Z direction are provided with wall portions 67 that extend from these edges in the Y direction away from the first member 3. In this embodiment, the wall portions 67 are integrally formed with the side wall portion 21 of the second member 4. As shown in Figure 4, the wall portions 67 have a shape that follows the operating part 5 when viewed from the X direction in a side view. This reduces the possibility of the operating part 5 being unintentionally operated when the second member 4 is pressed against another object in the Y direction. In other words, it is possible to suppress unintended liquid spraying.

[0057] The spray operation of the spraying device 1 will be described with reference to Figures 6 and 7. Figure 6 shows the spraying device 1 in an unoperated state, where the operating part 52 is not operated by the user. As shown in Figure 6, in the unoperated state, the rotating member 6 is in the receiving position. The container body 110 is not pushed in relative to the nozzle 120. In the unoperated state, the distance D2 in the Z direction between the first hinge 511 and the tip 531 is more than half the length L1 of the case 2 in the Z direction. In this embodiment, the distance D2 is 39 mm and the length L1 is 75 mm.

[0058] When the cap 7 is attached to the case 2, the stopper 71 is positioned within the case 2 on the rotational path of the rotating member 6 from the receiving position to the spraying position. As a result, when the cap 7 is attached, the rotating member 6 contacts the stopper 71 before reaching the spraying position. This restricts the rotation of the rotating member 6. In this embodiment, the stopper 71 is in contact with the rotating member 6 when it is not being operated, i.e., when the rotating member 6 is in the receiving position. In this embodiment, angle A1 is obtuse when it is not being operated.

[0059] During the spraying operation, the user, for example, places their thumb on the operating part 52 and wraps their other fingers around the first component 3, gripping the case 2 in a way that encloses it.

[0060] During the spraying operation, the user pushes the operating part 52 in the Y direction toward the spray container 100. When pushed by the user, the operating part 52 rotates around the first hinge 511 toward the spray container 100, as shown in Figure 7. As a result of this rotation, the second hinge 512 moves toward the spray container 100 in the Y direction and toward the case tip 22 in the Z direction.

[0061] As the second hinge 512 moves, the connecting portion 53 rotates around the second hinge 512 so as to move away from the injection container 100. As the connecting portion 53 rotates, the tip portion 531 moves in the Z direction so as to move closer to the case tip portion 22. At this time, the tip portion 531 contacts the wall portion 66 within the contact groove 65, pushing the rotating member 6 from the receiving position to the injection position. As a result, the rotating member 6 reaches the injection position, and the liquid in the containment chamber R1 is injected from the injection opening 121.

[0062] According to the embodiment of this disclosure, the biasing unit 321 is configured to bias the rotating member 6 when the spray container 100 is not mounted, thereby maintaining the rotating member 6 in the receiving position. With this configuration, the rotating member 6 is reliably maintained in the receiving position when the spray container 100 is mounted, even without being held down by a finger. This makes it easy to position the spray container 100 in the correct position relative to the rotating member 6. Therefore, it is possible to realize a spray operation device 1 in which the spray container 100 can be easily replaced.

[0063] Furthermore, according to the embodiments of this disclosure, the rotation axis 62 of the rotating member 6 has, in cross-section, a first dimension S1 in the Z direction and a second dimension S2 in the Y direction intersecting the first dimension S1. The second dimension S2 is greater than both the distance D1 between the biasing portion 321 and the shaft holding portion 322, and the first dimension S1. With this configuration, when the rotating member 6 rotates from the receiving position to another position, the biasing portion 321 is pushed by the rotation axis 62 and deflects away from the shaft holding portion 322. On the other hand, the biasing portion 321 pushes back against the rotation axis 62 by an elastic force that tries to return to a state with less deflection. As a result, the rotating member 6 is biased via the rotation axis 62 and maintained in the receiving position when not mounted.

[0064] Furthermore, since the biasing portion 321 also serves as part of the bearing portion 32, the biasing portion 321 can be provided to the injection control device 1 while keeping the number of parts to a minimum. Therefore, the cost and number of processes in the manufacturing of the injection control device 1 can be reduced.

[0065] Furthermore, according to the embodiment of this disclosure, the shaft holding portion 322 is also configured to bend when pushed by the rotating shaft 62 when the rotating member 6 is in a position other than the receiving position. As a result, the shaft holding portion 322 has the same function as the biasing portion 321. Therefore, when the rotating member 6 is in a position other than the receiving position, both the biasing portion 321 and the shaft holding portion 322 are in a bent state when pushed by the rotating shaft 62. The biasing portion 321 and the shaft holding portion 322 push back against the rotating shaft 62 with an elastic force that tries to return them to a state with less bending, thereby maintaining the rotating member 6 in the receiving position.

[0066] When both the biasing portion 321 and the shaft holding portion 322 are deflected, the deflection of each is smaller than the deflection of the biasing portion 321 when only the biasing portion 321 is deflected. Therefore, in the design of the spraying device 1, the elastic modulus of the biasing portion 321 can be increased. Consequently, the strength of the biasing portion 321 can be improved.

[0067] Furthermore, according to the embodiment of this disclosure, the biasing portion 321 is formed integrally with the case 2. This reduces the number of parts in the spray operating device 1 compared to the case 2 where a separate biasing portion is provided. Therefore, the cost and number of processes in the manufacturing of the spray operating device 1 can be reduced.

[0068] Furthermore, according to the embodiment of this disclosure, a base end opening 25 is provided at the base end 23 of the case. This allows the spray container 100 to be attached to the spray operating device 1 with a portion of the container body 110 extending to the outside of the case 2 through the base end opening 25. Therefore, spray containers 100 of various lengths can be attached to the spray operating device 1.

[0069] Furthermore, according to the embodiment of this disclosure, the distance D2 between the first hinge 511 and the tip portion 531 in the Z direction is more than half the length L1 of the case 2. With this configuration, the dimensions of the actuation part 5 in the Z direction are larger compared to a configuration in which the distance D2 is less than half the length L1 of the case 2. As a result, the deformation of the actuation part 5 is greater in response to the movement of the user pushing the operating part 52, and the force required to rotate the rotating member 6 can be reduced.

[0070] According to embodiments of this disclosure, the stopper 71 of the cap 7 is configured to contact the rotating member 6 within the case 2 and restrict the rotation of the rotating member 6. With this configuration, while the cap 7 is installed, the rotation of the rotating member 6 to the spraying position is suppressed, thereby reducing the possibility of unintended spraying.

[0071] Furthermore, since the stopper 71 is located inside the case 2 while the cap 7 is attached, the possibility of the stopper 71 being damaged by external impacts is reduced. This further suppresses unintended spraying.

[0072] This disclosure is not limited to the embodiments described above, and can be implemented in various other forms. For example, in the above description, a groove 26 is provided as a restricting portion that restricts the relative movement of the nozzle 120 with respect to the case 2, but the restricting portion may be in a form other than a groove, as long as it can restrict the relative movement.

[0073] Furthermore, although the above description assumes that case 2 has divided first member 3 and second member 4, the disclosure is not limited thereto. For example, the second member 4 may be connected to the first member 3 in a manner that prevents it from being removed. For example, the first member 3 and the second member 4 may be connected by a hinge. Also, the first member 3 and the second member 4 may be integrally formed if it is possible to replace the injection container 100.

[0074] The number of bearing portions 32 may be one or three or more. In each bearing portion 32, the biasing portion 321 may be located below the shaft holding portion 322. At least one of the biasing portion 321 and the shaft holding portion 322 may be formed as a separate member from the case 2 and fixed to the case 2. The shaft holding portion 322 does not have to be configured in the same way as the biasing portion 321. For example, the elastic modulus of the shaft holding portion 322 may be greater than that of the biasing portion 321. That is, when the rotating member 6 is in a position other than the receiving position, the deflection of the shaft holding portion 322 may be less than the deflection of the biasing portion 321.

[0075] Furthermore, although the above description assumes that the case 2 is provided with a bearing portion 32 and the rotating member 6 is provided with a rotating shaft 62, the present disclosure is not limited thereto. For example, the case 2 may be provided with a rotating shaft, and the rotating member 6 may be provided with a bearing portion that receives the rotating shaft.

[0076] Furthermore, although the above description assumes that a base end opening 25 is provided at the base end 23 of the case, the base end opening 25 does not necessarily have to be provided. However, by providing the base end opening 25, spray containers 100 of different lengths can be attached to the spray operation device 1.

[0077] The cap 7 does not necessarily need to be provided with a stopper 71.

[0078] By appropriately combining any embodiment or modification from the various embodiments or modifications described above, the effects of each can be achieved. Furthermore, combinations of embodiments with each other, combinations of examples with each other, and combinations of embodiments with examples are possible, as well as combinations of features from different embodiments or examples.

[0079] While this disclosure is adequately described in relation to preferred embodiments with reference to the accompanying drawings, various variations and modifications will be obvious to those skilled in the art. Such variations and modifications should be understood to be included within the scope of this disclosure as defined by the attached claims.
