In the push-down head type ejection container of Patent Document 1, when the cylindrical operating body is screwed off from the cylindrical base, the cylindrical base tends to rotate (co-rotate) together, and separation is not reliable.

The shoulder cover unit structure of Patent Document 2 is attached to the container body by fitting into an annular undercut provided on the inner circumferential side of the mounting cup, but the inner circumferential surface of the mounting cup is divided into eight parts, for example. Because it is formed so that it can be expanded outward in the radial direction by the crimp claws, it is not perfectly circular, and the ease of attachment and detachment varies depending on the fitting location, making attachment and detachment of the unit unstable.

The present invention aims to provide an exterior product that can be easily and reliably attached and detached.

The exterior product of the present invention includes a cover member 20 equipped with an engaging protrusion 22c that engages with the discharge container 2 from the outer peripheral side, and an operating member 30 rotatably attached to the cover member 20. The protrusion 22c is provided on a flexible piece (inner peripheral wall 22, D) that is flexible or swingable in the direction of approaching and separating from the discharge container 2, and the operating member 30 rotates the operating member 30. It is characterized by being equipped with an abutting portion 32c that changes engagement/disengagement of the engagement protrusion 22c with the discharge container 2 by bending or swinging the flexible piece (inner circumferential wall 22, D). It is said that

In the above-mentioned exterior product, it is preferable that the flexible piece (inner peripheral wall 22) extends in the rotational direction of the operating member 30. Alternatively, it is preferable that the flexible piece (inner circumferential wall 22, D) extends in a direction substantially perpendicular to the rotating direction of the operating member 30.

In addition, a flexible piece (inner peripheral wall 22, D) is attached to the abutted portion 22d of the contact portion 32c or the flexible piece (inner peripheral wall 22, D) that contacts the contact portion 32c, in accordance with the amount of rotation of the operating member 30. ) is preferably provided with inclined surfaces S, S1, S2 for bending or swinging.

Further, it is preferable that the contact portion 32c is located on the outer circumferential side of the abutted portion 22d, and the inclined surface S is provided on the outer circumferential side of the abutted portion 22d. Alternatively, it is preferable that the abutting portion 32c is located on the inner circumferential side of the abutted portion 22d, and the inclined surface S is provided on the outer circumferential side of the abutting portion 32c. Alternatively, it is preferable that the abutting portion 32c be located on the outer circumferential side of the abutted portion 22d, and the inclined surface S be provided on the inner circumferential side of the abutting portion 32c. Alternatively, it is preferable that the abutting portions 32c are located on the inner circumferential side and the outer circumferential side of the abutted portion 22d.

The discharge product of the present invention is characterized by comprising a discharge container 2 and the above-mentioned exterior parts 10, 10A, 10B, 10C, 10D, and 10E.

In the exterior product of the present invention, since the engaging protrusion of the cover member is engaged with the outer periphery of the discharge container, which is easy to form with high precision, the engagement protrusion can be reliably switched between engagement and non-engagement, and the rotation It can be easily attached and detached with just one operation.

In addition, if the flexible piece extends in the direction of rotation of the operating member, the length of the flexible piece can be increased while suppressing the height of the exterior product, compared to, for example, a case where the flexible piece extends in a direction perpendicular to the rotational direction. This allows the flexible piece to bend easily, making it easier to attach and detach the exterior item. If the flexible piece extends in a direction substantially perpendicular to the rotating direction of the operating member, for example, compared to a case where the flexible piece extends in the rotating direction of the operating member, it is possible to sufficiently bend the flexible piece while suppressing the outer diameter of the exterior product. For example, it can be used as an exterior package suitable for a small-diameter discharge container.

If the contact part or the contacted part of the flexible piece that contacts the contact part is provided with an inclined surface for gently bending or swinging the flexible piece in accordance with the amount of rotation of the operating member, the engagement The depth of engagement of the mating protrusion with the discharge container can be easily adjusted by the amount of rotation.

When the abutting part is located on the outer circumferential side of the abutted part and the inclined surface is provided on the outer circumferential side of the abutting part or the inner circumferential side of the abutting part, the engaging protrusion is engaged with the discharge container. The structure is such that the flexible piece is deflected when the engaging protrusion is engaged with the discharge container, and the repulsive force from the flexible piece is always applied to the abutting part while the engagement protrusion is engaged with the discharge container, so the operating member is held down by the repulsive force. As a result of restricting unintended rotation of the operating member, the attachment state of the outer package to the discharge container can be stably maintained. When the abutting parts are located on the inner and outer circumferential sides of the abutted part, there is no pressure from the flexible piece both when the engagement protrusion engages with the discharge member and when the engagement is released. Since repulsive force can be applied to the contact portion, unintended rotation of the operating member can be restricted.

When the abutting part is located on the inner circumferential side of the abutted part and the inclined surface is provided on the outer circumferential side of the abutting part, when the engagement protrusion and the discharge container are disengaged, the bending piece Since the engagement state is maintained unless the operation member is rotated, the attachment state of the exterior product to the discharge container can be stably maintained.

Next, a discharged product 1 according to an embodiment of the present invention will be described in detail based on the drawings. As shown in FIGS. 1 to 3, the discharge product 1 includes a discharge container 2 and an exterior package 10 that is removably attached to the discharge container 2.

The discharge container 2 is a so-called aerosol can that includes a container body 3 and an aerosol valve 4.

The container body 3 is made of metal such as tin or aluminum, and includes a bottom 3a, a generally cylindrical body 3b rising from the outer peripheral end of the bottom 3a, and a body 3b extending upward while gradually decreasing in diameter from the upper end of the body 3b. The dome portion 3d has a lower end secured to the upper end of the shoulder portion 3c by winding. The upper end of the dome portion 3d is open, and a bead portion 3e (see FIGS. 2 and 3) is provided to frame this opening. The outer shape of the bead portion 3e is circular in plan view.

The aerosol valve 4 includes a bottomed cylindrical stem 4a having a stem hole on the side surface, a housing that accommodates the stem 4a in a vertically movable manner, an elastic body (spring) that always urges the stem 4a upward, and a stem 4a. The container includes a stem rubber that closes the stem hole before being pushed down or tilted, and deforms to open the stem hole when the stem 4a is pushed down or tilted, and a mounting cup 4b that fixes the housing to the container body. .

The aerosol valve 4 is fixed to the container body 3 by placing the outer peripheral edge 4b1 of the mounting cup 4b over the bead portion 3e of the container body 3 and caulking it. When crimping, the plurality of crimp pawls are expanded radially outward and the inner circumferential wall of the mounting cup 4b is pushed radially outward, so that the inner circumferential wall has a substantially polygonal planar shape, but the outer circumferential edge 4b1 of the mounting cup 4b maintains a circular shape in plan view. Note that the outer circumferential edge 4b1 of the mounting cup 4b and the inner circumferential wall 22 of the cover member 20 of the exterior product 10, which will be described later, are located concentrically (axially) in a plan view.

The discharge container 2 configured as described above is filled with an undiluted solution and a propellant for discharging the undiluted solution.

As shown in FIG. 2, the exterior product 10 includes a cover member 20 provided with an engaging protrusion 22c that engages with the discharge container 2 from the outer circumferential side, and is rotatably attached to the cover member 20, so that the exterior product 10 can be attached and removed. It also includes an operating member 30 for performing operations. Note that the rotation is performed around the central axis N of the discharge product 1 (the central axis of the discharge container 2, the central axis of the cover member 20).

The cover member 20 includes an outer peripheral wall 21 , an inner peripheral wall 22 located inside the outer peripheral wall 21 , and a mounting portion 23 located inside the inner peripheral wall 22 .

The outer peripheral wall 21 forms the outer shape of the cover member 20 and has a substantially cylindrical shape, and marks 21a and 21b, which serve as a guide for rotation operation, are provided on the outer peripheral surface at intervals in the rotation direction of the operation member 30. There are two spaced apart. When the position of the needle 32a of the operating member 30, which will be described later, points to the mark 21a on the front side, it indicates that the exterior product 10 is fixed to the discharge container 2. When the mark 21b on the rear side is pointing, it indicates that the exterior product 10 is detachable from the discharge container 2 (see FIGS. 1 and 3). Further, a protruding portion 21c that protrudes rearward is provided to match the rear shape of the operating member 30.

The inner circumferential wall 22 includes a connecting wall 22a extending radially inward from the inner circumferential surface of the outer circumferential wall 21, and an annular wall 22b extending in the circumferential direction (rotation direction of the operating member 30) from the tip of the connecting wall 22a. . This inner circumferential wall 22 has flexibility in the direction of approaching and separating from the discharge container 2 (radial direction). In short, it functions as a bending piece that bends in the radial direction (especially in the radial direction) when external force is applied, and returns to its original position when the external force is removed. Three inner peripheral walls 22 are provided every 120 degrees in plan view.

Near the tip of the annular wall 22b, which has a generally arcuate shape in plan view, is an engaging protrusion 22c that engages with the outer peripheral edge 4b1 of the mounting cup 4b, and an abutted part 22d that abuts with an abutting part 32c of an operating member 30, which will be described later. and is provided. In plan view, the engaging protrusion 22c protrudes in the radial inward direction, and the abutted portion 22d protrudes in the radial outward direction. The protruding length of the engaging protrusion 22c in the radial inward direction is such that when the inner circumferential wall 22 is not bent in the radial inward direction (FIG. 2D), it does not engage with the outer circumferential edge 4b1 of the mounting cup 4b, but is bent (FIG. 2B). It is adjusted so that it engages with the The abutted portion 22d includes an inclined surface S that gradually projects radially outward from the direction in which the abutting portion 32c abuts toward the advancing direction of the abutting portion 32c. This is to cause the inner circumferential wall 22 to flex gently in accordance with the amount of rotation of the operating member 30. Further, a flat surface F is provided that extends from the radially outer end of the inclined surface S in the advancing direction of the contact portion 32c.

Reference numeral 22e indicates a regulating piece that regulates excessive rotation of the operating member 30.

The attachment portion 23 has a substantially cylindrical shape and is fixed to the outer peripheral wall 21 by a connecting portion 23a extending in a radially outward direction. This attachment portion 23 mainly functions as a base for rotatably attaching the operating member 30 to the cover member 20.

The operating member 30 includes a nozzle portion 31 attached to the stem 4a and a base portion 32 that supports the nozzle portion 31.

The nozzle part 31 includes a discharge nozzle 31a for discharging the stock solution in a desired state such as mist or foam, and an operation lever 31b for performing a discharge operation to discharge the stock solution (see FIG. 1). . The lower end of the discharge nozzle 31a is approximately cylindrical and communicates with the stem 4a. The operating lever 31b is rotatably supported on the base 32, and when you put your finger on the operating lever 31b and pull it backwards, the stem 4a is pushed down through the discharge nozzle 31a and the aerosol valve is opened. 4 is now open. Note that the stock solution discharged from the depressed stem 4a is discharged to the outside via the discharge nozzle 31a.

The upper side of the base 32 is substantially mountain-shaped when viewed from the front, and the discharge nozzle 31a and part of the operating lever 31b protrude from an opening provided in the front. One needle 32a corresponding to the two marks 21a and 21b of the cover member 20 is provided on the outer periphery. The lower side of the base 32 includes an external fitting part 32b which is approximately cylindrical and rotatably fits onto the mounting part 23, and an abutting part 32c provided along the outer peripheral surface of the annular wall 22b. An abutting piece 32d is provided that comes into contact with the regulating piece 22e of the cover member 20 when the operating member 30 is rotated by a predetermined amount. Three contact portions 32c are provided at intervals of 120 degrees in plan view to match the contact portions 22d.

Next, the operation of the exterior product 10 will be explained. As described above, the protrusion length of the engaging protrusion 22c in the radial inward direction is adjusted so that it does not engage with the outer circumferential edge 4b1 of the mounting cup 4b when the inner circumferential wall 22 is not bent in the radial inward direction. Therefore, in the initial state (FIGS. 2C and 2D) in which the abutting portion 32c is not in contact with the abutted portion 22d, the cover member 20 and the mounting cup 4b are not engaged and cannot be freely attached and detached. can. At this time, the needle 32a points to the mark 21b on the rear side (see FIG. 3). Note that even if an attempt is made to turn the needle 32a further backward than the mark 21b on the rear side, the abutting piece 32d abuts against the regulating piece 22e and cannot be rotated.

As the operating member 30 is rotated so that the needle 32a is aligned with the mark 21a on the front side, the contact portion 32c provided on the outer circumferential side of the contact portion 22d eventually comes into contact with the contact portion 22d. . Since the abutted portion 22d has an inclined surface S on the outer peripheral side (on the abutting portion 32c side), the inner peripheral wall 22 gradually bends in the radial direction in accordance with the slope of the inclined surface S. As a result, the engaging protrusion 22c gradually moves radially inward and engages with the outer peripheral edge 4b1 of the mounting cup 4b from the outer peripheral side of the mounting cup 4b. That is, the exterior product 10 is fixed to the discharge container 2 (see FIGS. 2A and 2B). Further, since the contact portion 32c receives a biasing force (repulsive force) in the radially outward direction from the inner circumferential wall 22, the operating member 30 is pressed down by the biasing force, and unintended rotation of the operating member 30 is restricted. be done. When the needle 32a is rotated until it points to the mark 21a on the front side, the contact portion 32c crosses the slope S and comes into contact with the flat surface F.

When the user wants to replace the outer package 10 with a new discharge container 2 after using up the contents, the operating member 30 is rotated so that the needle 32a is aligned with the mark 21b on the rear side. Then, the abutting portion 32c no longer abuts the abutted portion 22d, the inner peripheral wall 22 returns to its original position before being bent, and the engagement between the engaging protrusion 22c and the mounting cup 4b is released. Remove it from the empty old dispensing container 2 with the engagement released, and with the mounting cup 4b of the new dispensing container 2 inserted inside the inner peripheral wall 22, insert the needle 32a into the mark 21a on the front side. By rotating the operating member 30 so as to match them, the exterior product 10 can be fixed to a new discharge container 2.

In this manner, the exterior product 10 configured as described above can bend the inner circumferential wall 22 by rotating the operating member 30 to switch between engagement and non-engagement of the engagement protrusion 22c with the discharge container 2. Therefore, even a consumer can easily attach and detach the discharge container 2 and the outer package 10, and it is possible to separate the discharge container 2 and the outer package 10 and promote the reuse of the outer package 10. Further, since the engaging protrusion 22c can be moved in and out in the radial direction, damage to the engaging protrusion 22c during attachment and detachment can be suppressed, and the exterior product 10 can be used for a long period of time.

FIG. 4 shows another exterior product 10A. As shown in the figure, this exterior product 10A has a generally cylindrical shape as a whole and does not include a protrusion 21c, and the operating lever 31b is not a trigger type but a push-down type. As shown in FIG. 5, the internal structure is such that the protruding length of the engaging protrusion 22c in the radial inward direction engages with the outer peripheral edge 4b1 of the mounting cup 4b in a state in which the inner peripheral wall 22 is not bent (FIG. 5B). This is different from the exterior product 10 of FIG. 1 in that the engagement is adjusted to be released by bending radially outward (FIG. 5D). In addition, the abutted part 22d protrudes in the radial direction of the inner circumferential wall 22, the abutted part 32c is located on the inner circumferential side of the abutted part 22d, and the outer circumferential side of the abutted part 32c ( The inclined surface S is provided on the abutted portion 22d side), the tip of the inner peripheral wall 22 also serves as the regulating piece 22e, the nozzle portion 31 is connected to the cover member 20, and the engagement protrusion. This is different from the exterior product 10 shown in FIG. 1 in that 22c, abutted portions 22d, and abutted portions 32c are provided every 90 degrees (there are four) in plan view.

In the initial state (FIG. 5B) in which the abutting part 32c is not in contact with the abutted part 22d, the exterior product 10A has the cover member 20 engaged with the mounting cup 4b, and cannot be freely attached or detached. . At this time, the needle 32a points to the mark 21a on the front side. When an attempt is made to turn the needle 32a further forward than the mark 21a on the front side, the contact piece 32d contacts the regulation piece 22e and cannot be rotated.

When the operating member 30 is rotated so that the needle 32a is aligned with the mark 21b on the rear side, the abutting portion 32c eventually comes into contact with the abutted portion 22d. Since the contact portion 32c includes the slope S, the inner circumferential wall 22 gradually bends radially outward in accordance with the slope of the slope S. As a result, the engagement protrusion 22c gradually moves radially outward and disengages from the outer peripheral edge 4b1 of the mounting cup 4b (see FIG. 5D). That is, the exterior product 10 can be removed from the discharge container 2. When the needle 32a is rotated until it points to the mark 21b on the rear side, the contact portion 22d crosses the slope S and comes into contact with the flat surface F.

If you want to replace the outer package 10A with a new dispensing container 2 because the contents are used up, etc., remove the needle 32a by aligning it with the mark 21b on the rear side, and attach the mounting cup 4b of the new dispensing container 2 to the inner peripheral wall. 22 and rotate it until the needle 32a points to the mark 21a on the front side, the inner circumferential wall 22, which had been bent radially outward by the contact portion 32c, returns to its original position before being bent. Returning to , the engaging protrusion 22c engages with the outer peripheral edge 4b1 of the mounting cup 4b. That is, the exterior product 10A is attached to the discharge container 2.

FIG. 6 shows yet another exterior product 10B. As shown in the figure, the external appearance is similar to the exterior product 10A shown in FIG. 4, and is generally cylindrical as a whole. Further, the operating lever 31b is also of a push-down type. On the other hand, the internal structure is similar to the exterior product 10 of FIG. 1, as shown in FIGS. 7 and 8. That is, a contact portion 32c is provided on the inner peripheral surface of the operating member 30, and a contact portion 22d is provided on the inner peripheral wall 22 of the cover member 20. A portion of the inner circumferential wall 22 functions as the deflecting piece D. Specifically, a portion (three locations in the circumferential direction) of the inner circumferential wall 22 protrudes in the radial inward direction, and the protruding portion serves as the bending piece D.

The flexible piece D has a generally plate-like shape when viewed from the side, and the vicinity of the upper end is fixed, and the side and lower ends are not fixed and are free ends. This state can also be expressed as the bending piece D extending in a direction (downward) substantially orthogonal to the rotational direction of the operating member 30. When the bending piece D comes into contact with the contact portion 32, the lower end side bends toward the discharge container 2 (radially inward direction). An inclined surface S is provided on the outer peripheral surface of the abutted portion 22d of the flexible piece D. The inclined surface S is inclined in the rotating direction of the operating member 30, similarly to the exterior products 10 and 10A shown in FIGS. 1 and 4. In other words, the outer diameter gradually increases clockwise (see FIG. 8D). Therefore, by rotating the operating member 30 around the central axis of the cover member 20, it is possible to adjust whether or not the flexible piece D is pushed (deflected) by the contact portion 32c and the amount of push (deflection amount). Note that the inclined surface S is also inclined in the vertical direction (see FIG. 7). Specifically, the outer diameter is inclined so that it gradually increases in the radial outward direction as it goes in the extending direction (downward) of the flexible piece D. In this way, by reducing the overhang caused by the inclined surface S near the upper end of the flexible piece D and increasing the overhang caused by the inclined surface S near the lower end of the flexible piece D, the flexible piece D provided with the engagement protrusion 22c is It is possible to suppress deflection near the upper end while greatly deflecting the vicinity of the lower end.

In the exterior product 10B having the above configuration, the characters "SET" and "REUSE" are provided on the outer circumferential surface of the outer circumferential wall 21 of the cover member 20 as marks that serve as a guide when rotating the operating member 30. When the needle 32a of the operating member 30 points to “REUSE”, the contact portion 32c does not bend the flexible piece D, and the engagement protrusion 22c provided at the lower end of the flexible piece D is connected to the discharge container 2. are not engaged, and therefore the outer package 10B is in a state where it can be attached to and detached from the discharge container 2 (see FIG. 8D). Therefore, the outer package 10B can be removed from the discharge container 2 that has been used, or the outer package 10B can be placed on a new discharge container 2. When the needle 32a of the operating member 30 points to "SET", the contact portion 32 is bending the flexible piece D in the radially inward direction, and the engaging protrusion 22c is engaged with the mounting cup 4b ( (See Figure 8B). Therefore, the exterior product 10B cannot be removed from the discharge container 2. In this way, also in this exterior product 10B, by rotating the operating member 30, the flexible piece D can be bent to switch between engagement and non-engagement of the engagement protrusion 22c with the discharge container 2.

FIG. 9 shows yet another exterior product 10C. As shown in the figure, this exterior product 10C does not have an operating lever 31b, and a so-called push button is used as the nozzle portion 31. The operating member 30 is provided with a guide cylinder portion 33 that guides the vertical movement of the push button (see FIG. 11A). The cover member 20 does not include an inner peripheral wall 22 and a mounting portion 23. As shown in FIG. 10, the outer peripheral wall 21 includes a lower cylindrical portion 24 on the lower side, and an upper cylindrical portion 25 having a smaller diameter than the lower cylindrical portion 24 and extending upward from the upper end of the lower cylindrical portion 24, A portion of the upper cylinder portion 25 is a flexible piece D. The flexible piece D has the same configuration as the exterior product 10B shown in FIG. That is, it has a generally plate-like shape when viewed from the side, and the vicinity of the upper end is fixed, and the side and lower ends are not fixed and are free ends. A long hole 25a extending in the rotational direction of the operating member 30 is provided in a portion of the upper cylinder portion 25 that is not the flexible piece D. The inner peripheral surface of the operating member 30 is provided with a convex portion 34 that is fitted into the elongated hole 25a. When the convex portion 34 is fitted into the elongated hole 25a, rotation of the operating member 30 is allowed, but removal of the operating member 30 from the cover member 20 is restricted. Note that the operating member 30 rotates within the range of the elongated hole 25a, and excessive rotation is restricted.

The exterior product 10C having the above configuration is different from the exterior product 10B shown in FIG. is provided. Further, "REUSE" is located in front of "SET". When the needle 32a of the cover member 20 points to “REUSE”, the contact portion 32c does not bend the flexible piece D, and the engagement protrusion 22c provided on the flexible piece does not engage with the discharge container 2. Therefore, the exterior product 10C is in a state where it can be attached to and detached from the discharge container 2 (see FIG. 11D). Therefore, the outer package 10C can be removed from the discharge container 2 that has been used, or the outer package 10C can be placed on a new discharge container 2. When the needle 32a of the cover member 20 points to "SET", the contact portion 32 is bending the flexible piece D in the radial inward direction, and the engagement protrusion 22c is engaged with the mounting cup 4b. Therefore, the outer package 10C cannot be removed from the discharge container 2 (see FIG. 11B). In this manner, also in this exterior product 10C, by rotating the operating member 30, the flexible piece D can be bent to switch between engagement and non-engagement of the engagement protrusion 22c with the discharge container 2.

FIG. 12 shows yet another exterior product 10D. As shown in FIG. 13, this exterior product 10D is different from other exterior products 10, 10A, in that the inclined surface S is provided on the inner peripheral side (inner peripheral surface) of the contact portion 32c of the operating member 30. It is different from 10B and 10C. This inclined surface S is provided so that the wall thickness of the operating member 30 gradually becomes thinner. With such an inclined surface S, the outer diameter of the exterior product 10D can be made small, and it is also possible to match the outer diameter with the discharge container 2 having a small diameter (for example, 40 mm in diameter). The abutted portion 22d that abuts the inclined surface S is provided on the outer peripheral surface of the cover member 20, has a rib shape, and extends in the vertical direction. The abutted portion 22d is inclined in the vertical direction. Specifically, the outer diameter is inclined so that it gradually increases in the radial outward direction as it goes in the extending direction (downward) of the flexible piece D. Since the inclined surface S is also inclined in the vertical direction, the abutted portion 22d is partially accommodated in the recess formed by the inclined surface S, as shown in FIG. 14C. The other configurations are the same as the exterior product 10C shown in FIG. That is, as shown in FIG. 14, by rotating the operating member 30, the flexible piece D can be bent to switch between engagement and non-engagement of the engagement protrusion 22c.

FIG. 15 shows yet another exterior product 10E. In this exterior product 10E, as shown in FIG. 16, a substantially cylindrical abutted portion 22d is provided to protrude upward from the flexible piece D. Two abutting parts 32c are provided so as to sandwich the upper part of the abutted part 22d from the inner circumferential side and the outer circumferential side (see FIGS. 16 and 17D). The contact portion 32c1 on the inner circumferential side and the contact portion 32c2 on the outer circumferential side include inclined surfaces S1 and S2, respectively. The inclined surface S1 of the inner circumferential abutting portion 32c1 is for gradually pushing the abutted portion 22d radially outward in accordance with the rotational operation of the operating member 30. On the other hand, the inclined surface S2 of the contact portion 32c2 on the outer peripheral side is for gradually pushing the contacted portion 22d in the radial inward direction. The inclined surface S1 and the inclined surface S2 are inclined in the same direction. For example, it is inclined so that the outer diameter decreases clockwise.

As shown in FIG. 16, the upper end of the flexible piece D is fixed, and the side and lower ends are not fixed and are free ends. D1), so when the abutted part 22d moves radially inward, the lower end of the flexible piece D moves radially outward, and when the abutted part 22d moves radially outward, the flexible piece D The lower end of D moves radially inward. That is, the flexible piece D can swing like a seesaw with the fixed part D1 as the rotation axis. By swinging the flexible piece D around the fixed portion D1 in this manner, the amount of movement of the engagement protrusion 22c in the direction toward and away from the discharge container 2 can be increased. For example, in other exterior products 10, 10A, 10B, 10C, and 10D, the engaging protrusion 22c can only be moved in either the radially inward or radially outward direction from the initial state, but in this exterior product 10E, It can be moved in either the radially inward direction or the radially outward direction from the initial state. Therefore, even if the outer diameter of the exterior product 10E is small, it is easy to ensure the amount of movement of the engagement protrusion 22c necessary for switching engagement/disengagement with the discharge container 2.

In the exterior product 10E having the above configuration, when the operating member 30 is rotated and the needle 32a provided on the outer circumferential surface of the operating member 30 is aligned with "SET" provided on the outer circumferential surface of the cover member 20, the The contact portion 22d is pushed radially outward by the contact portion 32c1 on the inner peripheral side. As a result, the lower end of the flexible piece D moves radially inward, and the engagement protrusion 22c provided at the lower end engages with the discharge container 2 (see FIGS. 17A and 17B). When the needle 32a of the operating member 30 is set to "REUSE", the abutted part 22d is pushed radially inward by the abutting part 32c2 on the outer circumferential side. As a result, the lower end of the flexible piece D moves radially outward, and the engagement between the engagement protrusion 22c and the discharge container 2 is released (see FIGS. 17C and 17D). That is, by rotating the operating member 30, engagement/disengagement of the engagement protrusion 22c can be switched.

Although the embodiments of this invention have been described above, this invention is not limited to the above embodiments, and can be implemented with various changes within the scope of this invention. For example, the inclined surface S may be provided on both the abutting portion 32c and the abutted portion 22d. The marks 21a and 21b may be provided on the operating member 30, and the needle 32a may be provided on the cover member 20. The number of engaging protrusions 22c, abutted parts 22d, and abutted parts 32c is not limited to three or four, but may be five or more. The needle 32a may be set in the fixed state when it is aligned with the mark 21b on the rear side, and may be set in the released state when the needle 32a is aligned with the mark 21a on the front side. The flexible piece D may extend not only downward but also upward. In this case, the vertical inclination of the inclined surface S is also reversed. Further, the location where the engagement protrusion 22c engages is not limited to the mounting cup 4b, but can be changed as appropriate, such as the bead portion 3e of the container body 3, as long as it is an engageable recess. In FIG. 16, the abutted portion 22d is made to protrude above the fixed portion D1, but it may be made to protrude downward. In this case, if the abutted part 22d is moved radially inward, the engagement protrusion 22c will also be moved radially inward, and if the abutted part 22d is moved radially outward, the engagement protrusion 22c will also be moved radially inward. It begins to move radially outward.
