[0009] Hereinafter, an embodiment of a trigger-type spray container according to the present invention will be described with reference to the drawings. [First embodiment] FIG. 1 is a side view of a trigger-type spray container 10 according to a first embodiment of the present invention. The trigger spray container 10 comprises a container 11 and a trigger spray 12 attached to the container 11. The container 11 includes a container body 11a for containing a liquid, and a cylindrical mouth portion 11b extending upward from the upper surface of the container body 11a. An axis 11c of the mouth portion 11b passes through the center of the mouth portion 11b and extends in the vertical direction. The trigger spray 12 is attached to the mouth portion 11b.

[0010] In Fig. 1, the trigger-type spray container 10 is shown in an upright position in which the trigger-type spray container 10 is placed upright so that the mouth 11b opens upward. Here, in Fig. 1, only the upper part of the container 11 is shown, and the lower part of the container 11 is not shown.

[0011] The trigger-type spray 12 comprises a main body (not shown) equipped with a pressure generating unit that generates spray pressure, a trigger 15 that operates the pressure generating unit, a case 16 (shroud) that houses the main body, a nozzle 17 that sprays the liquid in the container 11 in response to operation of the trigger 15, and a cap 18 that is connected to the mouth portion 11b. The pressure generating section generates pressure by the relative movement of a piston and a cylinder which is linked to the operation of a trigger 15 .

[0012] In Fig. 1, the forward direction of the trigger type spray container 10 is indicated by arrow A. The nozzle 17 is provided at the front end of the trigger type spray container 12 and sprays liquid forward. In the following description, the spray direction of liquid from the nozzle 17 is assumed to be the forward direction. In the following description, the up-down direction means the up-down direction when the trigger type spray container 10 is placed in an upright position as shown in Fig. 1. Unless otherwise specified, the axial direction means the axial direction of the mouth portion 11b.

[0013] In the side view of FIG. 1, the case 16 includes a case front portion 16a located forward with respect to the axis 11c, and a case rear portion 16b located rearward with respect to the axis 11c. The cap 18 is cylindrical and arranged coaxially with the axis 11c. The cap 18 is rotatably connected to the lower part of the main body and is located below the case 16. The trigger sprayer 12 is attached to the mouth portion 11b by screwing a female thread provided on the inner periphery of the cap 18 into a male thread provided on the outer periphery of the mouth portion 11b.

[0014] An annular groove 11d recessed radially inward is formed below the cap 18 on the outer periphery of the upper part of the container 11. The groove 11d is formed by positioning the outer periphery of the mouth 11b radially inward relative to the cap 18 between the lower surface 18a of the cap 18 and the upper surface of the container body 11a.

[0015] The nozzle 17 is connected to the front end of the main body and is located in front of the case front part 16a. The trigger 15 is in the form of a lever extending downward and forward from the main body behind the nozzle 17. The trigger 15 extends downward and forward from the lower part of the case front part 16a. The trigger 15 rotates about a rotation shaft (not shown) provided at the upper end of the trigger 15. The upper end of the trigger 15 is located above the cap 18. In FIG. 1, the state in which the trigger 15 is rotated so as to be pulled backward is shown by an imaginary line as trigger 15'. When the trigger 15 is pulled backward, liquid is sprayed from the nozzle 17. The trigger-type spray container 10 is provided with an operation restricting member 20 that restricts the operation of the trigger 15.

[0016] Fig. 2 is a plan view of the operation restricting member 20 as viewed from above. Fig. 3 is a plan view of the trigger-type spray container 10 as viewed from above. In Fig. 3, the container 11 is not shown. 1 to 3, the operation restricting member 20 comprises an attachment portion 21 that is rotatably attached to the outer periphery of the mouth portion 11b, a forward extension portion 22 that extends radially outwardly forward from the attachment portion 21, and a rearward extension portion 23 that extends radially outwardly rearward from the attachment portion 21. The operation restricting member 20 also includes a rotation restricting portion 24 that restricts the rotation of the operation restricting member 20 . The forward extension 22 of the operation restricting member 20 is provided with a stopper portion 25 that restricts the operation of the trigger 15 and a stopper-side rotation restricting portion 26 that restricts the rotation of the operation restricting member 20.

[0017] The operation restricting member 20 is attached to the mouth portion 11b below the case 16. The mounting portion 21 of the operation restricting member 20 is attached to the mouth portion 11b so as to surround the cap 18 from the periphery. The mounting portion 21 includes a peripheral wall portion 21a that surrounds the cap 18, and an inner flange portion 21b that extends radially inward from a lower edge of the peripheral wall portion 21a. The basic shape of the peripheral wall portion 21a is cylindrical, but the peripheral wall portion 21a includes an opening 21c in a part of the outer periphery. 2, the mounting portion 21 is formed in a C-shape having an opening 21c at a part of the outer periphery of the peripheral wall portion 21a when viewed in the axial direction of the mouth portion 11b. A notch 21d is provided at the middle portion in the circumferential direction of the inner flange portion 21b.

[0018] The mounting part 21 is attached to the mouth part 11b by engaging the inner flange part 21b with the groove part 11d. Moreover, the mounting part 21 is supported by the mouth part 11b via the cap 18 by engaging the peripheral wall part 21a with the outer periphery of the cap 18. The peripheral wall portion 21 a extends upward to a position higher than the upper end of the cap 18 .

[0019] The peripheral wall portion 21a is located behind the trigger 15. The forward extension portion 22 extends from the upper end of the front surface of the peripheral wall portion 21a toward the forward trigger 15. In a side view, the forward extension portion 22 is a plate-like portion that extends forward with a slightly upward-sloping front. In a top view, the forward extension portion 22 is a rectangle that extends in the front-rear direction. The stopper portion 25 is formed by the front edge of the forward extension portion 22. The stopper portion 25 has a linear shape that is perpendicular to the front-rear direction. The stopper portion 25 is located behind the trigger 15 and abuts against the rear surface 15a of the upper portion of the trigger 15 from behind.

[0020] The stopper side rotation restricting portion 26 is a protruding portion that protrudes forward from an end in the width direction (left and right direction) of the stopper portion 25. The stopper side rotation restricting portion 26 protrudes forward from the rear surface 15a and is located to the side of the trigger 15.

[0021] The rear extension portion 23 extends rearward from the upper end of the rear surface of the peripheral wall portion 21a. The rear extension portion 23 extends from the mounting portion 21 to the opposite side to the front extension portion 22. The rear extension portion 23 is a plate-like portion that extends rearward along the lower surface of the case rear portion 16b in a side view. The rear extension portion 23 is a rectangular portion that extends in the front-rear direction in a top view.

[0022] The mounting portion 21, the front extension portion 22, and the rear extension portion 23 configure a main body portion 20a as a main portion of the operation restricting member 20. The rotation restricting portion 24 is connected to the main body portion 20a. The rotation regulating portion 24 comprises a support plate portion 30 extending rearward from the rear surface of the peripheral wall portion 21a, a regulating wall 31 erected upward from the support plate portion 30, a weakening portion 32 connecting the support plate portion 30 and the rearward extending portion 23, and a pressing portion 33 provided at the rear end portion of the rotation regulating portion 24.

[0023] The support plate 30 includes a pair of arms 30a, 30b extending rearward from the rear surface of the peripheral wall 21a, and a connecting portion 30c connecting the rear ends of the arms 30a, 30b to each other in the width direction. One arm portion 30a is disposed on one outer side (left side) of the rear extension portion 23. The other arm portion 30b is disposed on the other outer side (right side) of the rear extension portion . The connecting portion 30c is disposed rearward of the rear extension portion 23.

[0024] The arms 30a, 30b and the connecting portion 30c are arranged to surround the rear extension portion 23. The arms 30a, 30b and the rear extension portion 23 are provided on the same plane as the rear extension portion 23. As shown in FIG. 2 , a gap is formed between the arms 30a, 30b and the connecting portion 30c and the rear extension portion 23. The arm portions 30a, 30b are provided at their front ends with thin portions 30d, which are formed by partially reducing the plate thickness of the arm portions 30a, 30b.

[0025] The weakened portion 32 connects the rear edge of the rear extension portion 23 and the front edge of the connecting portion 30c. The plate thickness of the weakened portion 32 is smaller than the plate thickness of the rear extension portion 23 and the plate thickness of the connecting portion 30c. The weakened portion 32 is provided only in a portion of the rear edge of the rear extension portion 23 in the width direction, and is narrow. In this manner, the weakened portion 32 is formed to have a lower strength than the members surrounding the weakened portion 32. For this reason, when an external force is applied between the rear extension portion 23 and the rotation restricting portion 24, the weakened portion 32 breaks preferentially.

[0026] The restriction wall 31 is integrally provided with a side wall portion 31a erected upward from the outer edge of the rear portion of the arm portion 30b, and a rear wall portion 31b erected upward from the rear edge of the connecting portion 30c. The pressing portion 33 is a plate-shaped portion extending rearward from the lower end of the rear wall portion 31b.

[0027] The operation restricting member 20 is rotatable around the opening 11b. In detail, the operation restricting member 20 is rotatable about the axis 11c of the mouth portion 11b with the inner flange portion 21b of the mounting portion 21 engaged with the groove portion 11d. The operation restricting member 20 is restricted from moving in the axial direction (up and down direction) by the inner flange portion 21b engaging with the groove portion 11d.

[0028] FIG. 4 is a plan view showing a state in which the operation restricting member 20 has been rotated from the state shown in FIG. FIG. 3 shows the operation restricting member 20 in a "restricting position" where the operation of the trigger 15 is restricted by the stopper portion 25. FIG. 4 shows a state in which the operation restricting member 20 is in a "restriction release position" in which the restriction of the operation of the trigger 15 by the stopper portion 25 is released.

[0029] 1 to 3, in the "restricted position" state, operation restricting member 20 restricts the operation of pulling trigger 15 backward by positioning stopper portion 25 on the operation path of trigger 15. In FIG. 1, stopper portion 25 abuts against rear surface 15a of trigger 15. Therefore, in the "restricted position" state, the user cannot pull trigger 15, and liquid is not sprayed from nozzle 17. Here, the operation trajectory of trigger 15 is the trajectory of trigger 15 when trigger 15 in FIG. 1 moves to the position of trigger 15'. Since the stopper portion 25 abuts against the rear surface 15a of the upper part of the trigger 15 which slopes downward at the front, it is possible to shorten the front-to-rear length of the forward extension portion 22. As a result, it is possible to increase the rigidity of the forward extension portion 22, and the operation of the trigger 15 can be effectively restricted by the stopper portion 25.

[0030] In the state shown in FIGS. 1 and 3, the rotation of the operation restricting member 20 is restricted by the rotation restricting portion 24 and the stopper-side rotation restricting portion 26. As shown in FIG. In detail, the rotation restricting portion 24 restricts the rotation of the operation restricting member 20 by the side wall portion 31 a of the restricting wall 31 coming into contact with the side surface of the trigger sprayer 12 .

[0031] Here, the side of the trigger sprayer 12 has one side 12a (left side) located on the side where the opening 21c of the mounting part 21 is located, and the other side 12b (right side) located opposite the one side 12a. The other side surface 12b of the side wall portion 31a abuts against the side surface of the rear end portion of the case rear portion 16b. The rear wall portion 31b of the restriction wall 31 covers the case rear portion 16b from the rear. The rear wall portion 31b is connected to the side wall portion 31a, thereby increasing the rigidity of the side wall portion 31a.

[0032] The stopper-side rotation restricting portion 26 restricts the rotation of the operation restricting member 20 by contacting a side surface of the trigger sprayer 12. In detail, the stopper-side rotation restricting portion 26 contacts a side surface of the upper part of the trigger 15 at the other side surface 12b.

[0033] A side wall portion 31a located at the rear of the mouth portion 11b abuts against the other side surface 12b, thereby restricting the rotation of the operation restricting member 20 in the clockwise direction in FIG. The stopper-side rotation restricting portion 26 located in front of the mouth portion 11b restricts the rotation of the operation restricting member 20 in the counterclockwise direction in FIG. 3 by abutting against the other side surface 12b. In this manner, by providing the side wall portion 31a and the stopper-side rotation restricting portion 26, the rotation of the operation restricting member 20 can be restricted in both directions of rotation.

[0034] 3, the side wall portion 31a of the rotation restricting portion 24 and the stopper-side rotation restricting portion 26 restrict the rotation of the operation restricting member 20, so that the operation restricting member 20 is maintained in the "restricted position". In other words, the rotation restricting portion 24 and the stopper-side rotation restricting portion 26 restrict the operation restricting member 20 from changing from the "restricted position" to the "unrestricted position".

[0035] When the pressing portion 33 is strongly pressed downward, the weakened portion 32 of the rotation restricting portion 24 breaks, and the support plate portion 30 bends downward starting from the thin portion 30d. As a result, the restricting wall 31 is displaced downward from the case rear portion 16b, and the restriction of the rotation of the operation restricting member 20 by the side wall portion 31a is released. In Fig. 1, the rotation restricting portion 24 in the downwardly displaced state is shown by a virtual line as the rotation restricting portion 24'.

[0036] When the restriction on rotation by the rotation restricting portion 24 is released, the operation restricting member 20 can be rotated clockwise in Fig. 3. Fig. 4 shows a state in which the operation restricting member 20 has been rotated 90 degrees to the "restriction release position." 3 and is removed from the operation path of trigger 15. This allows the user to eject liquid from nozzle 17 by pulling trigger 15.

[0037] For example, when a user purchases a trigger-type spray container 10, the user can check whether or not the trigger-type spray 12 has already been sprayed by checking the state of the rotation restricting portion 24. If the weakened portion 32 is broken and the rotation restricting portion 24 is displaced downward, there is a possibility that the trigger-type spray 12 has already been sprayed. If the weakened portion 32 is not broken, it can be assumed that the trigger-type spray 12 has not been sprayed before.

[0038] When using the trigger-type spray container 10 for the first time, the user presses down the pressing portion 33 to release the restriction by the rotation restricting portion 24. Next, the operation restricting member 20 is rotated from the "restricted position" to the "restricted position." This allows the trigger 15 to be operated.

[0039] 5 is a rear view of the operation restricting member 20 in the "restriction release position" state. In FIG. 5, the operation restricting member 20 is shown in cross section. 4 and 5, in the "unrestricted position", the front extension 22 and the rear extension 23 extend to both the left and right sides so as to be perpendicular to the trigger spray 12 that extends long in the front-to-rear direction. A user can hold the trigger spray container 10 by auxiliary use of the front extension 22 and the rear extension 23. For example, a user can hold the trigger spray container 10 by hooking their fingers on the front extension 22 and the rear extension 23 from below.

[0040] As shown in Fig. 1, the operation restricting member 20 covers the cap 18 from the outside with the mounting portion 21. With this, when the operation restricting member 20 is mounted on the mouth portion 11b, it becomes difficult to access the cap 18 from the outside, and it is possible to prevent the trigger sprayer 12 from being illegally removed from the container 11. This makes it possible to prevent other liquids from being mixed into the container 11 or being replaced with other liquids. In addition, as described above, when the operation restricting member 20 is mounted in the "restricted position", it is also impossible to pull the trigger 15. That is, when the trigger-type spray container 10 is seen and the restriction by the rotation restriction part 24 is not released, it can be assumed that the trigger-type spray 12 has not been illegally removed from the container 11 and that the trigger 15 has not been operated. In other words, the operation restriction member 20 has a tamper-evident function.

[0041] The operation restricting member 20 is attached when the trigger-type spray container 10 is manufactured. The operation restricting member 20 is attached to the mouth portion 11b from the side of the mouth portion 11b through the opening 21c of the C-shaped attachment portion 21 so as to push open the opening 21c. Here, since the side wall portion 31a and the stopper-side rotation restricting portion 26 are disposed on the other side surface 12b opposite to the opening 21c, even when the attachment portion 21 is attached from the side, the side wall portion 31a and the stopper-side rotation restricting portion 26 can be appropriately abutted against the other side surface 12b. Since the inner flange portion 21b is provided with the notch 21d, it is easy to push open the opening 21c.

[0042] As described above, according to the first embodiment to which the present invention is applied, the trigger-type spray container 10 comprises the container 11 and the trigger-type sprayer 12 attached to the mouth portion 11b of the container 11, and the trigger-type sprayer 12 comprises a trigger 15 and a nozzle 17 that sprays the liquid contained in the container 11 in response to operation of the trigger 15. The trigger-type spray container 10 comprises an operation restricting member 20 that is rotatable around the mouth portion 11b, and the operation restricting member 20 comprises a stopper portion 25 that is located on the operation trajectory of the trigger 15 and restricts the operation of the trigger 15, and is rotatable between a restricting position where the operation of the trigger 15 is restricted by the stopper portion 25 and a restricting release position where the stopper portion 25 is retracted from the operation trajectory. According to this configuration, when the operation restricting member 20 is rotated around the mouth portion 11b, it is possible to switch between a restricted position where the operation of the trigger 15 is restricted by the stopper portion 25 and a restricted release position where the stopper portion 25 is retracted from the operation trajectory. Therefore, with a simple structure in which the operation restricting member 20 is rotated around the mouth portion 11b, it is possible to suppress inadvertent operation of the trigger 15.

[0043] The operation restricting member 20 also includes a rotation restricting portion 24 that abuts against the trigger spray 12 to restrict rotation of the operation restricting member 20 from the restricting position. The rotation restricting portion 24 is connected to the main body portion 20a of the operation restricting member 20 via a weakened portion 32, and when the weakened portion 32 is broken and the rotation restricting portion 24 is displaced, the restriction on rotation by the rotation restricting portion 24 is released. According to this configuration, when the weakened portion 32 is not broken, the operation restricting member 20 cannot be rotated, and the operation restricting member 20 is maintained in a restricting position that restricts the operation of the trigger 15. This effectively prevents the trigger 15 from being inadvertently operated. Also, by checking the state of the weakened portion 32, it is easy to check whether the trigger 15 has already been operated.

[0044] In addition, the main body portion 20a includes an attachment portion 21 that is rotatably attached to the outer periphery of the mouth portion 11b, a forward extension portion 22 that extends radially outward from the attachment portion 21, and a rearward extension portion 23 that extends from the attachment portion 21 on the opposite side to the forward extension portion 22, and a stopper portion 25 is provided on the forward extension portion 22, and a rotation regulating portion 24 is connected to the rearward extension portion 23. According to this configuration, the rotation restricting portion 24 is connected to the rearward extending portion 23 extending on the opposite side to the forward extending portion 22 on which the stopper portion 25 that restricts the operation of the trigger 15 is provided, so that it is easy to ensure space for providing the rotation restricting portion 24 and it is possible to easily provide the rotation restricting portion 24. Furthermore, when using the trigger type spray container 10, the forward extending portion 22 and the rearward extending portion 23 can be used auxiliary to hold the trigger type spray container 10, making it easy to use the trigger type spray container 10.

[0045] Furthermore, the mounting part 21 is C-shaped with an opening 21c on a part of the outer periphery when viewed in the axial direction of the mouth part 11b, and is mounted laterally to the mouth part 11b through the opening 21c. The forward extension part 22 is provided with a stopper-side rotation restricting part 26 that abuts against the trigger sprayer 12 to restrict rotation of the operation restricting member 20. The trigger sprayer 12 has one side surface 12a located on the side where the opening 21c is located and the other side surface 12b located on the opposite side to the one side surface 12a, and the rotation restricting part 24 and the stopper-side rotation restricting part 26 abut against the other side surface 12b. According to this configuration, the operation restricting member 20 can be easily attached to the mouth portion 11b from the side by utilizing the opening 21c of the C-shaped attachment portion 21. In addition, since the rotation restricting portion 24 and the stopper side rotation restricting portion 26 abut against the other side surface 12b opposite to the opening 21c side, even when the operation restricting member 20 is attached from the side by utilizing the opening 21c of the C-shaped attachment portion 21, the rotation restricting portion 24 and the stopper side rotation restricting portion 26 can be appropriately abutted against the trigger-type spray 12. Furthermore, since the rotation restricting portion 24 and the stopper side rotation restricting portion 26 are provided separately on the other side surface 12b side as the rear extension portion 23 and the front extension portion 22, the rotation of the operation restricting member 20 can be restricted in both directions of rotation.

[0046] Further, the stopper side rotation restricting portion 26 abuts against the side surface of the trigger 15 . According to this configuration, a stopper portion 25 that regulates the operation of the trigger 15 and a stopper side rotation regulating portion 26 are provided on the forward extension portion 22, and the stopper side rotation regulating portion 26 abuts against the side of the trigger 15, so that the stopper portion 25 and the stopper side rotation regulating portion 26 can be arranged compactly near the trigger 15.

[0047] [Second embodiment] A second embodiment to which the present invention is applied will be described below with reference to Figures 6 to 11. In this second embodiment, parts configured similarly to the first embodiment are given the same reference numerals and descriptions thereof will be omitted. The second embodiment differs from the first embodiment in that the operation restricting member 220 is configured to be set on the trigger sprayer 12 from below.

[0048] FIG. 6 is a side view of a trigger-type spray container 210 according to the second embodiment. The trigger spray container 210 includes a container 211 and a trigger spray 12. The container 211 includes a container body 211a for containing liquid and a cylindrical mouth portion 211b extending upward from the upper surface of the container body 211a. An axis 211c of the mouth portion 211b passes through the center of the mouth portion 211b and extends in the vertical direction. The trigger sprayer 12 is attached to the mouth portion 211b. In FIG. 1, only the upper part of the container 211 is shown, and the lower part of the container 211 is omitted.

[0049] The trigger sprayer 12 is attached to the mouth portion 211b by screwing a female thread provided on the inner circumference of the cap 18 into a male thread provided on the outer circumference of the mouth portion 211b. An annular locking flange 211d is provided below the lower surface 18a of the cap 18 above the mouth portion 211b and protruding radially outward. An annular groove 211e is formed between the lower surface 18a and the locking flange 211d in the mouth 211b, the groove 211e being recessed radially inward with respect to the cap 18 and the locking flange 211d.

[0050] The trigger-type spray container 210 is provided with an operation restricting member 220 that restricts the operation of the trigger 15. Fig. 7 is a plan view of the operation restricting member 220 as viewed from above. Fig. 8 is a plan view of the trigger-type spray container 210 as viewed from above. In Fig. 8, the container 211 is not shown. 6 to 8, the operation restricting member 220 includes an attachment portion 221 that is rotatably attached to the outer periphery of the mouth portion 211b, a forward extension portion 222 that extends radially outward from the attachment portion 221 toward the front, and a rear extension portion 223 that extends radially outward from the attachment portion 221 toward the rear. The operation restricting member 220 also includes a rotation restricting portion 224 that restricts the rotation of the operation restricting member 220 . A stopper portion 225 that restricts the operation of the trigger 15 is provided on the forward extension portion 222 of the operation restricting member 220.

[0051] The operation restricting member 220 is attached to the opening 211b below the case 16. The mounting portion 221 of the operation restricting member 220 is attached to the opening portion 211b so as to surround the cap 18 from the periphery. The mounting portion 221 includes a cylindrical peripheral wall portion 221a that surrounds the cap 18, and an annular inner flange portion 221b that extends radially inward from the lower edge of the peripheral wall portion 221a. The mounting portion 221 also has a plurality of slits 221c (see FIGS. 6 and 11) that extend from the lower end of the peripheral wall portion 221a to the upper and lower middle portions of the peripheral wall portion 221a.

[0052] The mounting portion 221 is fixed to the mouth portion 211b by engaging the inner flange portion 221b with the groove portion 211e. Moreover, the mounting portion 221 is supported by the mouth portion 211b via the cap 18 by engaging the peripheral wall portion 221a with the outer periphery of the cap 18. The peripheral wall portion 221 a extends upward to a position higher than the upper end of the cap 18 .

[0053] The forward extension 222 extends from the upper end of the front surface of the peripheral wall 221a toward the forward trigger 15. In a side view, the forward extension 222 is a plate-like portion that extends forward with a slightly upwardly-inclined front. In a top view, the forward extension 222 is a rectangle that extends in the front-rear direction. The stopper portion 225 is formed by the front edge of the forward extension portion 222. The stopper portion 225 has a linear shape that is perpendicular to the front-rear direction. The stopper portion 225 is located behind the trigger 15 and abuts against the rear surface 15a of the upper portion of the trigger 15 from behind.

[0054] The rear extension portion 223 extends rearward from the upper end of the rear surface of the peripheral wall portion 221a. The rear extension portion 223 extends from the mounting portion 221 in the opposite direction to the front extension portion 222. The rear extension portion 223 is a plate-like portion that extends rearward along the lower surface of the case rear portion 16b in a side view. The rear extension portion 223 is a rectangular portion that extends in the front-rear direction in a top view. A rear end 223a of the rear extension 223 is formed to be narrower than a front portion of the rear extension 223.

[0055] The mounting portion 221, the front extension portion 222, and the rear extension portion 223 configure a main body portion 220a as a main portion of the operation restricting member 220. The rotation restricting portion 224 is connected to the main body portion 220a. The rotation regulating portion 224 includes a support plate portion 230 provided behind the rear extension portion 223, a regulating wall 231 erected upward from the support plate portion 230, a weakening portion 232 connecting the support plate portion 230 and the rear extension portion 223, and a pressing portion 233 provided at the rear end portion of the rotation regulating portion 224.

[0056] The support plate portion 230 includes a pair of left and right arm portions 230a, 230b arranged outwardly of the rear end portion 223a of the rear extension portion 223, and a connecting portion 230c connecting the rear ends of the arm portions 230a, 230b in the width direction. The front edge of the connecting portion 230c is connected to the rear edge of the rear end portion 223a. The connecting portion that connects the front edge of the connecting portion 230c and the rear edge of the rear end portion 223a is a thin-walled portion 230d that is partially thin. The thin-walled portion 230d is linear and extends in the width direction.

[0057] The arm portions 230a, 230b and the connecting portion 230c are provided on the same plane as the rear extension portion 223. When viewed from above as in Figure 7, a gap is formed in the width direction between the arm portions 230a, 230b and the rear end portion 223a.

[0058] A pair of weakened portions 232 are provided on the left and right sides of the rear end portion 223a. One (left) weakened portion 232 connects one arm portion 230a to a side edge of the rear end portion 223a. The other (right) weakened portion 232 connects the other arm portion 230b to a side edge of the rear end portion 223a. The weakened portion 232 connects the arm portions 230a, 230b and the rear end portion 223a in the width direction.

[0059] The plate thickness of the weakened portion 232 is smaller than the plate thickness of the rear end portion 223a and the plate thickness of the arm-shaped portions 230a, 230b. Moreover, the weakened portion 232 is provided only on a portion of the front-rear length of the arm-shaped portions 230a, 230b, and is narrow. In this manner, the weakened portion 232 is formed to have a lower strength than the members surrounding the weakened portion 232. For this reason, when an external force is applied between the rear extension portion 223 and the rotation restriction portion 224, the weakened portion 232 breaks preferentially.

[0060] The regulating wall 231 is integrally formed with one side wall portion 231a erected upward from the outer edge portion of the arm-shaped portion 230a, the other side wall portion 231b erected upward from the outer edge portion of the arm-shaped portion 230b, and a rear wall portion 231c erected upward from the rear edge portion of the connecting portion 230c. The rear wall portion 231c connects the rear end of the one side wall portion 231a and the rear end of the other side wall portion 231b in the width direction. The pressing portion 233 is a plate-like portion extending rearward from the upper end of the rear wall portion 231c.

[0061] The operation restricting member 220 is rotatable around the opening 211b. In detail, the operation restricting member 220 is rotatable about the axis 211c of the mouth portion 211b with the inner flange portion 221b of the mounting portion 221 engaged with the groove portion 211e. The operation restricting member 220 is restricted from moving in the axial direction (up and down direction) by the inner flange portion 221b engaging with the groove portion 211e.

[0062] FIG. 9 is a plan view showing a state in which the operation restricting member 220 has been rotated from the state shown in FIG. FIG. 8 shows a state in which the operation restricting member 220 is in a "restricting position" in which the operation of the trigger 15 is restricted by the stopper portion 225. FIG. 9 shows a state in which the operation restricting member 220 is in a "restriction release position" in which the restriction of the operation of the trigger 15 by the stopper portion 225 is released.

[0063] 6 to 8, in the "restricted position" state, operation restricting member 220 restricts the operation of pulling trigger 15 backward by positioning stopper portion 225 on the operation trajectory of trigger 15. In FIG. 6, stopper portion 225 abuts against rear surface 15a of trigger 15. Therefore, in the "restricted position" state, the user cannot pull trigger 15, and liquid is not sprayed from nozzle 17.

[0064] In the state shown in FIGS. 6 and 8, the rotation of the operation restricting member 220 is restricted by the rotation restricting portion 224. As shown in FIG. In detail, the rotation restricting portion 224 restricts the rotation of the operation restricting member 220 by abutting one side wall portion 231 a and the other side wall portion 231 b of the restricting wall 231 against the side surface of the trigger sprayer 12 .

[0065] The one side wall 231a abuts against the side surface of the rear end of the case rear portion 16b at one side surface 12a. The other side wall 231b abuts against the side surface of the rear end of the case rear portion 16b at the other side surface 12b. The rear wall 231c covers the case rear portion 16b from behind. The one side wall portion 231a restricts the rotation of the operation restricting member 20 in the counterclockwise direction in FIG. The other side wall portion 231b restricts the rotation of the operation restricting member 20 in the clockwise direction in FIG.

[0066] 8, the restriction wall 231 of the rotation restriction portion 224 restricts the rotation of the operation restriction member 220, so that the operation restriction member 220 is maintained in the "restricted position". In other words, the rotation restriction portion 224 restricts the operation restriction member 220 from being changed from the "restricted position" to the "unrestricted position".

[0067] When the pressing portion 233 is strongly pressed downward, the weakened portion 232 of the rotation restricting portion 224 breaks, and the support plate portion 230 bends downward starting from the thin portion 230d. As a result, the restricting wall 231 is displaced downward from the case rear portion 16b, and the restriction of the rotation of the operation restricting member 220 by the restricting wall 231 is released. In Fig. 6, the rotation restricting portion 224 in the downwardly displaced state is shown by a virtual line as the rotation restricting portion 224'.

[0068] When the restriction on rotation by the rotation restricting portion 224 is released, the operation restricting member 220 can be rotated clockwise or counterclockwise in Fig. 8. Fig. 9 shows a state in which the operation restricting member 220 has been rotated 90° to the "restriction release position." 8 and is removed from the operation path of trigger 15. This allows the user to pull trigger 15 to eject liquid from nozzle 17.

[0069] For example, when a user purchases the trigger spray container 210, the user can check whether the trigger spray 12 has already been sprayed by checking the state of the rotation restricting portion 224. If the weakened portion 232 is broken and the rotation restricting portion 224 is displaced downward, there is a possibility that the trigger spray 12 has already been sprayed. If the weakened portion 232 is not broken, it can be assumed that the trigger spray 12 has not been sprayed before.

[0070] When using the trigger-type spray container 210 for the first time, the user presses down the pressing portion 233 to release the restriction by the rotation restricting portion 224. Next, the user rotates the operation restricting member 220 from the "restricted position" to the "restricted position." This allows the trigger 15 to be operated.

[0071] FIG. 10 is a rear view of the "unrestricted position." 9 and 10, in the "unrestricted position", the front extension 222 and the rear extension 223 extend on both the left and right sides so as to be perpendicular to the trigger spray 12 that extends long in the front-rear direction. A user can hold the trigger spray container 210 by auxiliary use of the front extension 222 and the rear extension 223. For example, a user can hold the trigger spray container 210 by hooking their fingers on the front extension 222 and the rear extension 223 from below.

[0072] The operation restricting member 220 covers the cap 18 from the outside with the mounting portion 221. As a result, when the operation restricting member 220 is mounted on the mouth portion 211b, it becomes difficult to access the cap 18 from the outside, and it is possible to prevent the trigger sprayer 12 from being illegally removed from the container 211. This makes it possible to prevent other liquids from being mixed into the container 211 or from being replaced with other liquids. In addition, as described above, when the operation restricting member 220 is mounted in the "restricted position", it is also impossible to pull the trigger 15. That is, when the trigger-type spray container 210 is seen, if the restriction by the rotation restriction part 224 is not released, it can be considered that the trigger-type spray 212 has not been illegally removed from the container 211, and the trigger 15 has not been operated. In other words, the operation restriction member 220 has a tamper-evident function.

[0073] FIG. 11 is a side view showing a state in which the operation restricting member 220 is spaced downward from the trigger sprayer 12. As shown in FIG. 11, the operation restricting member 220 is in a lower position where the mounting portion 221 is spaced downward from the trigger spray 12. In this lower position, the operation restricting member 220 is received by the upper surface of the container body 211a with the mounting portion 221 fitted into the mouth portion 211b. When manufacturing the trigger spray container 210, the operation restricting member 220 is attached to the mouth portion 211b prior to the trigger spray 12. Thereafter, the cap 18 is screwed onto the mouth portion 211b, thereby attaching the trigger spray 12 to the mouth portion 211b.

[0074] In FIG. 6, the operation restricting member 220 is in an upper position where the mounting portion 221 has moved upward in the axial direction of the opening portion 211b with respect to the above-mentioned lower position. When the mounting portion 221 moves upward from the lower position, it climbs over the locking flange 211d while expanding in diameter, engages with the groove 211e, and returns to its original diameter. The presence of the slit 221c makes it easy to expand the diameter of the mounting portion 221. When the mounting portion 221 engages with the groove 211e at the upper position, the axial position of the mounting portion 221 is locked by the locking flange 211d, and it cannot move downward.

[0075] When the operation restricting member 220 moves from the lower position to the upper position, the one side wall portion 231a and the other side wall portion 231b of the restricting wall 231 engage with the case rear portion 16b from below. Therefore, even if the case rear portion 16b is sandwiched from both sides in the width direction by the one side wall portion 231a and the other side wall portion 231b, the operation restricting member 220 can be easily attached to the case rear portion 16b.

[0076] As described above, according to the second embodiment to which the present invention is applied, trigger-type spray container 210 includes container 211 and trigger-type spray 12, and trigger-type spray 12 includes trigger 15 and nozzle 17 for spraying liquid contained in container 211 in response to operation of trigger 15. Trigger-type spray container 210 includes operation restricting member 220 that is rotatable around mouth portion 211b, and operation restricting member 220 includes stopper portion 225 that is positioned on the operation trajectory of trigger 15 and restricts the operation of trigger 15, and is rotatable between a restricting position where operation of trigger 15 is restricted by stopper portion 225 and a restricting release position where stopper portion 225 is retracted from the operation trajectory. According to this configuration, when the operation restricting member 220 is rotated around the mouth portion 211b, it is possible to switch between a restricted position where the operation of the trigger 15 is restricted by the stopper portion 225 and a restricted release position where the stopper portion 225 is retracted from the operation trajectory. Therefore, with a simple structure in which the operation restricting member 220 is rotated around the mouth portion 11b, it is possible to suppress inadvertent operation of the trigger 15.

[0077] In addition, the operation restricting member 220 is provided with a rotation restricting portion 224 that abuts against the trigger spray 12 to restrict rotation of the operation restricting member 220 from the restricting position, and the rotation restricting portion 224 is connected to the main body portion 220a of the operation restricting member 220 via a weakened portion 232. When the weakened portion 232 is broken and the rotation restricting portion 224 is displaced, the restriction on rotation by the rotation restricting portion 224 is released. According to this configuration, when the weakened portion 232 is not broken, the operation restricting member 220 cannot be rotated, and the operation restricting member 220 is maintained in a restricting position that restricts the operation of the trigger 15. This makes it possible to effectively prevent the trigger 15 from being operated inadvertently. Moreover, by checking the state of the weakened portion 232, it is possible to easily check whether the trigger 15 has already been operated.

[0078] In addition, the main body portion 220a includes an attachment portion 221 that is rotatably attached to the outer periphery of the mouth portion 211b, a forward extension portion 222 that extends radially outward from the attachment portion 221, and a rearward extension portion 223 that extends from the attachment portion 221 on the opposite side to the forward extension portion 222, and a stopper portion 225 is provided on the forward extension portion 222, and a rotation regulating portion 224 is connected to the rearward extension portion 223. According to this configuration, since the rotation restricting portion 224 is connected to the rearward extending portion 223 extending on the opposite side to the forward extending portion 222 on which the stopper portion 225 that restricts the operation of the trigger 15 is provided, it is easy to ensure a space for providing the rotation restricting portion 224, and the rotation restricting portion 224 can be easily provided. Furthermore, when using the trigger type spray container 210, the forward extending portion 222 and the rearward extending portion 223 can be used auxiliary to hold the trigger type spray container 210, making it easy to use the trigger type spray container 210.

[0079] In addition, the mounting portion 221 can move in the axial direction of the mouth portion 211b from a lower position spaced downward from the trigger spray 12 to an upper position moved upward, and in the upper position, it engages with the mouth portion 211b to lock the axial position, and when in the locked state, the rotation regulating portion 224 regulates the rotation of the operation regulating member 220. According to this configuration, when the operation restricting member 220 moves in the axial direction of the opening 211b, the rotation restricting portion 224 restricts the rotation of the operation restricting member 220, thereby increasing the degree of freedom in the arrangement of the rotation restricting portion 224. Therefore, the rotation of the operation restricting member 220 can be effectively restricted by the rotation restricting portion 224.

[0080] Furthermore, in the locked state, the rotation restricting portion 224 abuts against both side surfaces of the trigger sprayer 12, that is, one side surface 12a and the other side surface 12b. According to this configuration, the rotation restricting portion 224 abuts against one side surface 12a and the other side surface 12b of the trigger sprayer 12, so that the rotation of the operation restricting member 220 can be restricted in both directions of rotation.

[0081] Although one embodiment of the present invention has been described above, the present invention is not limited to the specific embodiment, and various modifications and changes are possible within the scope of the spirit of the present invention described in the claims unless otherwise specifically limited in the above description. For example, the configuration of the above-mentioned embodiment can be appropriately added or deleted, and the configuration of one embodiment can be applied to another embodiment. Furthermore, the effects of the above-mentioned embodiment are merely examples of the effects resulting from the present invention, and do not mean that the effects of the present invention are limited to the above-mentioned effects. In the above embodiment, the position where the operation restricting member 20, 220 is rotated 90° from the "restricted position" has been described as the "restriction release position", but the present invention is not limited to this. The "restriction release position" does not have to be a position where it is rotated 90° as long as the stopper portion 25, 225 is retracted from the operation trajectory of the trigger 15. For example, the "restriction release position" may be a position where the operation restricting member 20, 220 is rotated 45° from the "restricted position". [Explanation of symbols]
