Description

  The present invention relates to a spray container capable of accurately managing the dosage for each dosage by limiting the number of times of spraying a chemical solution by a built-in pump mechanism.

  There has been proposed a spray container for a chemical solution with a built-in manual pump mechanism, which can count the number of sprays and prohibit the use of a spray more than a certain number of sprays (Patent Document 1).

  The spray container is configured by integrally combining a chemical container equipped with a pump mechanism, a carrier unit for storing the chemical container, and a casing with a lever type operation lever. Therefore, by operating the lever-type operation lever and driving the chemical liquid container in the axial direction via the carrier unit, the pump mechanism can be operated to spray the chemical liquid to the outside. Note that the carrier unit is rotated step by step by the ratchet mechanism for each spraying operation, and a certain number of stepping rotations are prohibited. In other words, the spray container can count the number of sprays from the beginning of use of the chemical solution in the chemical solution container and manage the end-of-use timing. Even if it becomes impossible to spray a fixed amount of chemical liquid, it is possible to avoid the problem of continuing use.

Special table 2003-504280 gazette

  According to such a conventional technique, since the number of sprays from the beginning of use of the chemical solution can only be counted, it is not applicable to the use of, for example, counting and managing the number of sprays of the chemical solution for which the dosage per one time is limited. There was a problem.

  Therefore, in view of the problems of the prior art, the object of the present invention is to combine the adapter body, ring member, and nozzle member with the container main body to which the pump mechanism is mounted, so that the number of times of spraying the chemical liquid by the pushing operation of the nozzle member each time the medicine is administered It is an object of the present invention to provide a spray container that can control the dosage accurately by restricting the amount of liquid.

  In order to achieve this object, the configuration of the present invention includes a container main body that stores a chemical solution, a pump mechanism that is operated by pushing an operation rod having a discharge hole in the axial direction, and a pump mechanism at the mouth of the container main body. An adapter to be mounted, a ring member that is rotatably accommodated in the adapter, and a nozzle member that has a tip that sprays a chemical solution from the pump mechanism and that pushes the operation rod. The ring member is a nozzle member. Can be manually set to an instruction position for instructing the spraying operation of the designated number of times and a lock position for prohibiting the pushing operation of the nozzle member, and a first step for stepping having an upward slope on the inner periphery of the ring member. And the second engaging piece for stepping having a downward slope are formed in the circumferential direction by the number of sets corresponding to the designated number of pushing operations, and the outer periphery of the nozzle member is provided for each pushing operation. 1st, 1st Engagement protrusions are formed that sequentially engage with each set of engagement pieces to cause the ring member to rotate stepwise, and the nozzle member rotates step by step from the indicated position to the locked position. The gist is to make it.

  Note that the upper end surface of the nozzle member can be formed as an oblique pressing surface that forms an anti-slip rib, and the engagement protrusion is engaged with the inner periphery of the ring member to push the nozzle member. An engaging piece for locking that locks inoperable can be formed.

  Further, the ring member is formed with an engagement protrusion that urges inward via a spring piece, and the adapter protrusion is elastically engaged with the adapter so that the last of the designated number of times of the nozzle member is formed. An engagement portion having a mountain-shaped cross section for stepping and rotating the ring member from the completion position of the pushing operation to the lock position may be formed, and the engagement protrusion is elastically engaged with the ring member in the ring member. An engagement ditch that produces a click feeling when the button is set at the indicated position or the lock position may be formed.

  Furthermore, the ring member can be provided with a permissible position between the lock position and the designated position that allows the pushing operation of the nozzle member without limitation.

  According to the configuration of the invention, the pump mechanism is attached to the mouth portion of the container body via the adapter, and is attached to the nozzle portion by operating the operation rod by pushing it in the axial direction via the nozzle member. The chemical solution can be sprayed from the tip in the form of a mist. The pump mechanism has a built-in return spring, and when the nozzle member is pushed and sprayed with the chemical liquid, it automatically returns to the original position via the return spring by removing the pressing force. That is, the pushing operation of the nozzle member includes a forward pushing operation and a returning returning operation each time, and the pump mechanism can repeat the chemical spraying operation only by repeatedly pushing the nozzle member.

  On the other hand, the ring member can be manually set to the indicated position and the locked position, and the nozzle member advances and rotates every time the ring member is pushed from the indicated position to the locked position. When the spraying operation is started after setting to the indicated position, the ring member rotates to the locked position by pushing the nozzle member a specified number of times, that is, the spraying operation by the nozzle member a specified number of times. It can be automatically prohibited to limit the number of sprays of the drug solution, and the dosage for each dosage can be managed accurately. However, the designated number of spraying operations by the nozzle member is set in advance to an arbitrary integer of 1 or 2 or more.

  When the nozzle member is pushed, the first engaging piece for stepping formed on the inner circumference of the ring member engages the upward protruding slope on the outer circumference of the nozzle member on the forward path of the pushing operation. The ring member is stepped and rotated by a half of the step pitch, and the second engaging piece for stepping is engaged with the inclined surface with the engaging protrusion engaging downward on the return path of the pushing operation of the nozzle member. The member is rotated stepwise by the remaining half of the stepping pitch. That is, when the nozzle member is pushed, the engagement protrusions on the outer periphery of the nozzle member are engaged with the upward slope of the first engagement piece in the forward path of the pushing operation, and only half the first half of the stepping pitch. The ring member is rotated stepwise, and in the return path of the subsequent pushing operation, the ring member is stepped and rotated by half of the latter half of the step pitch by engaging the downward slope of the second engagement piece, and the nozzle Each time the member is pushed, the ring member is rotated step by step by a predetermined step pitch.

  The first and second engagement pieces are prepared in a number corresponding to the designated number of pushing operations of the nozzle member. Therefore, the engagement protrusion on the outer periphery of the nozzle member has the ring member at the indicated position. When set, it is located above the slope of the first first engagement piece, and is located at the upper end of the slope of the last second engagement piece when the specified number of pushing operations of the nozzle member is completed. However, the engagement protrusions on the outer periphery of the nozzle member are sequentially engaged with the upward slope of the first engagement piece and the downward slope of the second engagement piece, respectively, in the forward path and the return path of the nozzle member. In order to cause the ring member to rotate stepwise in one direction, the ring member is formed in a lateral triangle having a top portion in the step rotation direction of the ring member. However, the engagement protrusions of the nozzle member may be, for example, circular or laterally semicircular as long as a similar stepping action can be achieved.

  The engagement protrusions on the outer periphery of the nozzle member can be locked so that the nozzle member cannot be pushed by engaging with a locking engagement piece formed on the inner periphery of the ring member. However, the ring member at this time is in the locked position, and the ring member automatically shifts to the locked position when the nozzle member has been pressed a specified number of times, and can be manually set to the locked position. it can.

  The engagement protrusion formed on the ring member is elastically engaged with the engagement portion having a cross-sectional cross-sectional shape formed on the adapter via a spring material. The ring member can be automatically stepped and rotated from the completion position to the lock position. In addition, by rotating the ring member to the locked position in this way, it is possible to reliably prevent the nozzle member from being pushed more than the specified number of times and thereby the chemical solution spraying operation exceeding the specified number of times. can do.

  If the engagement groove is formed in the adapter to cause the click feeling when the engagement protrusion of the ring member is elastically engaged at the indicated position and the lock position of the ring member, the ring member is indicated based on the click feeling. Can be easily manually set to the position and lock position. In addition, when providing an allowance position in a ring member, the engagement ditch | groove corresponding to an allowance position shall be additionally formed in an adapter, and a click feeling shall be produced also in an allowance position.

  When the ring member is provided with a permissible position, if the ring member is set at the permissible position, the ring member does not rotate stepwise even if the nozzle member is pushed, and the nozzle member is pushed and operated indefinitely. The drug solution can be sprayed as many times as the number of sprays.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The spray container is formed by integrally assembling the container body 10, the pump mechanism 20, the adapter 30, the ring member 40, and the nozzle member 50 (FIGS. 1 and 2). However, FIGS. 1A and 1B are a partially broken front view and a top view, respectively, and FIGS. 2A and 2B correspond to the X1-X1 line arrows in FIG. 1B, respectively. It is operation | movement description longitudinal cross-sectional view.

  The container body 10 is a cylindrical container having an upward mouth 11. A male screw 11 a is formed on the outer periphery of the mouth portion 11, and a predetermined amount of chemical solution (not shown) is stored in the container body 10. The container body 10 is provided with a detachable cap 61 that covers the nozzle member 50.

  The pump mechanism 20 is attached to the mouth portion 11 of the container body 10 via a screw-type adapter 30. The adapter 30 has a female screw 31 adapted to the male screw 11 a of the container body 10 in the lower half, and an intermediate wall 32 is formed on the upper part of the female screw 31.

  The pump mechanism 20 is configured by integrally assembling a casing 22, a piston 23, and an operation rod 24 coaxially. The casing 22 is internally provided with a return spring 25 that urges the piston 23 upward, and a lower end of the casing 22 is connected to a suction pipe 26 for a chemical solution that reaches the bottom of the container body 10.

  An upward flare 23 a is formed at the lower end of the piston 23, and the flare 23 a slides up and down in the casing 22 according to the upper and lower sides of the piston 23. A large-diameter measuring cup portion 22a is formed at the upper end of the casing 22, and an outer flange 22b is formed at the upper end edge of the cup portion 22a. A downward flare 24 a that slides along the inner surface of the cup portion 22 a is formed at the lower end portion of the operation rod 24. A shaft hole 23 b is formed in the lower portion of the piston 23, and the upper portion of the shaft hole 23 b opens into the cup portion 22 a via a flexible valve body 23 c attached to the piston 23. Note that a return port 22c communicating with the container body 10 is formed in the upper portion of the cup portion 22a. The upper half of the piston 23 is inserted upward into the downwardly stepped shaft hole 24b of the operating rod 24, and is positioned via a tapered portion at the upper end.

  In the casing 22, the outer flange 22 b is fixed to the upper end surface of the mouth portion 11 together with the packing 27 a through the adapter 30. Further, the operating rod 24 penetrates the intermediate wall 32 of the adapter 30 through the sealing material 27b so as to be slidable from the bottom to the top. The shaft hole 24b of the operation rod 24 opens at the upper end of the operation rod 24 as a discharge hole 24c.

  In the ring member 40, the large-diameter portion of the lower half is housed on the intermediate wall 32 of the adapter 30, and the small-diameter portion of the upper half is exposed to the outside. The ring member 40 is formed with knurls 40 a, 40 a... On the outer periphery of the small-diameter portion, and is prevented from being removed through engagement protrusions 33, 33. The ring member 40 is accommodated in the adapter 30 so as to be relatively rotatable.

  The nozzle member 50 is connected to the tip of the operation rod 24 of the pump mechanism 20 so that the lower half portion is housed in the ring member 40. The discharge hole 24c of the operation rod 24 opens toward the shaft hole 51 of the nozzle member 50, and a tip 52 that communicates with the shaft hole 51 through the communication hole 51a is laterally arranged at the upper end portion of the nozzle member 50. It is installed. The oblique upper end surface of the nozzle member 50 is formed on a pressing surface 53 that forms anti-slip ribs 53a, 53a. Inside the nozzle member 50, radial guide blades 54, 54 are formed, and the guide blades 54, 54 are formed with respect to the vertical guide grooves 34a, 34a formed in the high upward center tube 34 of the adapter 30. These are combined so as to be movable relative to each other vertically through the cutout grooves 54a.

  When the pressing surface 53 of the nozzle member 50 is pressed, the nozzle member 50 is lowered into the ring member 40 (FIG. 2B), and the operating rod 24 and the piston 23 are moved while the return spring 25 of the pump mechanism 20 is compressed. Lower. Further, when the pressing force applied to the pressing surface 53 is removed, the piston 23, the operating rod 24, and the nozzle member 50 are automatically returned to the original raised position via the return spring 25 (FIG. 2A). Therefore, for example, if the container body 10 is held in an upright state with a finger and a pressing force is repeatedly applied to the pressing surface 53 of the nozzle member 50 with the thumb or forefinger, the pump mechanism 20 is connected to the inside of the container body 10 via the suction pipe 26. Can be sucked and sprayed from the tip 52 of the nozzle member 50 to the outside in the form of a mist. Note that the pushing operation of the nozzle member 50 at this time can be performed with one hand.

  In the pump mechanism 20, the upward flare 23 a of the piston 23 functions as a check valve for sucking the chemical liquid when the piston 23 rises. At that time, the inside of the cup portion 22 a becomes negative pressure. The valve body 23c allows the chemical solution in the casing 22 to flow into the cup portion 22a. Further, the downward flare 24a of the operation rod 24 feeds the chemical solution in the cup portion 22a into the shaft hole 24b when the operation rod 24 and the piston 23 descend, and the discharge hole 24c, the shaft hole 51 of the nozzle member 50, and the communication. Spray from the tip 52 in the form of a mist through the hole 51a. A sufficient gap is formed between the piston hole 23 and the shaft hole 24b. Further, the return port 22c of the cup portion 22a returns a part of the air or chemical liquid in the cup portion 22a to the container body 10 when the operation rod 24 and the piston 23 are lowered. That is, the pump mechanism 20 can be operated by pushing the operating rod 24 in the axial direction via the nozzle member 50, and a certain amount of chemical solution can be sprayed from the tip 52 each time the nozzle member 50 is pushed.

  The ring member 40 has a designated position for instructing the nozzle member 50 to be pressed a specified number of times, that is, a designated position for spraying the nozzle member 50 by a specified number of times, a lock position for preventing the nozzle member 50 from being pressed, and a nozzle member 50 to be pressed. The nozzle member 50 can be manually rotated and set at a permissible position where the operation is allowed without limitation, and the nozzle member 50 rotates the ring member 40 step by step from the indication position to the lock position. Further, in order to realize the above functions, the outward engagement protrusions 55 and 55 are formed axisymmetrically at the lower end of the outer periphery of the nozzle member 50, and the first step for stepping is formed on the inner periphery of the ring member 40. The second engaging pieces 41, 41..., 42, 42... Are arranged in the circumferential direction, a low upward intermediate cylinder 35 is provided on the intermediate wall 32 of the adapter 30, and displayed on the upper outer periphery of the adapter 30. The windows 36 and 36 are provided symmetrically about the axis, and will be described below.

  A combined state of the adapter 30, the ring member 40, and the nozzle member 50 is shown in FIG. However, FIGS. 3A and 3B are exploded perspective views showing different directions. The adapter 30, the ring member 40, and the nozzle member 50 are integrally formed of a hard plastic material such as polypropylene and ABS, respectively.

  The lower half of the adapter 30 is a double cylinder connected via radial connecting pieces 37, 37 (FIGS. 4D and 4E), and the female screw 31 is formed on the inner cylinder side. An engagement rib 38 for the packing 27a when the pump mechanism 20 is mounted is formed above the female screw 31. A small cylinder 32a for penetrating the operation rod 24 of the pump mechanism 20 is suspended from the top surface of the intermediate wall 32, and a seal rib 32b for the seal material 27b is formed around the small cylinder 32a. However, FIGS. 4A and 4D are a top view and a bottom view of the adapter 30, respectively, and FIGS. 4B and 4C are views of arrows X2 and X3 in FIG. 4A, respectively. FIGS. 4E and 4F are cross-sectional views corresponding to the lines X4-X4 and X5-X5 in FIG. 4A, respectively.

  The upper end of the intermediate cylinder 35 on the intermediate wall 32 of the adapter 30 is formed on an outward slope (FIG. 4 (E)), and on the outer periphery of the intermediate cylinder 35, there are engaging portions 35a, 35a having a mountain cross section. , Vertical engaging grooves 35b, 35b... Are formed (FIG. 4A). However, two pairs of engaging concave grooves 35b, 35b,... Each having a pair of engaging portions 35a, 35a are arranged symmetrically on the outer periphery of the intermediate cylinder 35.

  On the outer periphery of the large-diameter portion of the lower half of the ring member 40, two sets of letters X and ∞ are displayed in axial symmetry in addition to numerals 1, 2,... (FIG. 3, FIG. 5 (B), ( C)). In addition, on the inner periphery of the ring member 40, two pairs of first and second engagement pieces 41, 41,... The pieces 43 and 43 and the open and closed concave grooves 45 and 45 are formed symmetrically (FIGS. 5A, 5D, and 5E). Each locking engagement piece 43 has an inward engagement protrusion 44 formed at the lower end of the downward spring piece 44a (FIGS. 5E and 5F). The spring piece 44a is urged inward. However, FIGS. 5A and 5D are a top view and a bottom view of the ring member 40, respectively, and FIGS. 5B and 5C are X6 arrow view and X7 arrow view of FIG. 5A, respectively. FIGS. 5 (E) and 5 (F) are cross-sectional views corresponding to the X8-X8 line of FIG. 5 (A), and end views corresponding to the X9-X9 line, respectively.

  When the ring member 40 is housed on the intermediate wall 32 of the adapter 30 (FIG. 2), the inward engagement protrusions 44, 44 on the inner periphery of the ring member 40 are respectively adapted to the adapter 30 according to the rotational position of the ring member 40. Can be elastically engaged with the engaging portion 35a on the outer periphery of the intermediate cylinder 35, the engaging grooves 35b, 35b... (FIG. 6). However, FIG. 6 illustrates a state in which the ring member 40 is rotated and manually set to the indicated position. At this time, each engagement protrusion 44 is engaged with the corresponding engagement portion 35a farthest clockwise. It engages with the concave groove 35b. At this time, the maximum number 5 on the ring member 40 is displayed on each display window 36 of the adapter 30 (FIG. 1).

  The first engaging pieces 41, 41... 42, 42... For stepping on the inner periphery of the ring member 40 together with the locking engaging pieces 43 and the recessed grooves 45 that are open upward and downward. 7 are arranged as shown in FIG. That is, each of the first engagement pieces 41, 41... Has an upward slope 41 a on one side, and extends upward from the vicinity of the lower end of the ring member 40. The second engaging pieces 42, 42,... Each have a downward inclined surface 42a on one side, and the first engaging pieces 41, 41,. They are arranged to correspond to each other. Further, the locking engagement piece 43 has a slope 43a corresponding to the slope 42a of the adjacent second engagement piece 42 on one side, and a steep slope 43b is formed on the concave groove 45 side. The first engagement piece 41 adjacent to the concave groove 45 also has a short inclined surface 41b on the concave groove 45 side.

  Engaging protrusions 55 and 55 at the lower end of the outer periphery of the nozzle member 50 are each formed in a lateral triangle (FIG. 3). The top of the engaging protrusion 55 faces in the direction opposite to the direction in which the slopes 41a and 42a of the first and second engaging pieces 41 and 42 are formed (FIG. 7). When the ring member 40 is in the designated position and the nozzle member 50 is not pushed, each engagement protrusion 55 is a second above the first engagement piece 41 adjacent to the concave groove 45 of the ring member 40. The upper end is slightly higher than the upper ends of the second engagement pieces 42, 42, and the lower end is slightly higher than the upper end of the locking engagement piece 43.

  Accordingly, when the nozzle member 50 is pushed and sprayed with the chemical solution, each engagement protrusion 55 descends and engages with the inclined surface 41a of the first engagement piece 41 immediately below, thereby moving the ring member 40 at a predetermined step. It is possible to make a step rotation by a half of the advance pitch (directions of arrows in FIGS. 7 and 8 (A1), FIGS. 8 (A2) and (B2)). Each engagement protrusion 55 is lowered to a position immediately below the lower end of the inclined surface 41 a of the first engagement piece 41 by the pushing operation of the nozzle member 50, and enters between the next first engagement piece 41. To do.

  Thereafter, when the nozzle member 50 returns to the original position via the return spring 25, each engagement protrusion 55 engages with the inclined surface 42a of the second engagement piece 42 immediately above, thereby causing the ring member 40 to move together. While rotating stepwise by a half of the stepping pitch in the direction, it rises to the next second engagement piece 42 (FIG. 8 (A3)). Further, at this time, the engaging protrusions 44, 44 of the ring member 40 are separated clockwise from the engaging groove 35b, which was initially engaged, by an amount corresponding to the stepping pitch (FIGS. 8B1 to 8B3) ). When the ring member 40 is rotated by the stepping pitch in this way, the display on each display window 36 of the adapter 30 changes from the numeral 5 to the numeral 4 ((A3) in the figure).

  Therefore, when the nozzle member 50 is pushed again to return to the original position, the ring member 40 further rotates in the same direction by a stepping pitch, and the display on each display window 36 changes to the numeral 3 (see FIG. 8 (A3) to (A5), (B3) to (B5)). Similarly, when the nozzle member 50 is pushed for the fifth time, each engagement protrusion 55 enters between the first engagement piece 41 and the locking engagement piece 43 (FIG. 9). (A1)), each engaging projection 44 of the ring member 40 is located in the closest counterclockwise direction of the corresponding engaging portion 35a on the adapter 30 side ((B1) in the figure). This is because each engagement protrusion 55 moves up and down while engaging with each set of the first and second engagement pieces 41, 41..., 42, 42.

  Subsequently, when the nozzle member 50 is returned to the original position, each engaging protrusion 55 is located between the inclined surface 42a of the second engaging piece 42 immediately above and the inclined surface 43a of the engaging piece 43 for locking. By passing the ring member 40, the ring member 40 is stepped and rotated by a half of the stepping pitch ((A2) in the figure), and each engaging projection 44 gets over the peak of the engaging part 35a (see the figure). (B2)). Therefore, each engagement protrusion 44 is urged inward via the spring piece 44a, and thus elastically engages with the slope of the outer surface of the engagement portion 35a to further rotate the ring member 40, thereby engaging the engagement member 35a. Engage with the engaging groove 35b adjacent to the joint portion 35a in the clockwise direction ((B3) in the figure). At this time, each of the engaging protrusions 55 is relatively advanced above the locking engagement piece 43 and engaged with the upper end of the engagement piece 43 (FIG. 3A), and the nozzle member 50 is engaged. The character X can be displayed on each display window 36. That is, in FIGS. 9A3 and 9B3, the ring member 40 is automatically set at the lock position.

  The ring member 40 in the locked position can be manually set at an allowable position by manually rotating the ring member 40 by a predetermined angle (FIGS. 9A4 and 9B4). At this time, each engagement protrusion 55 of the nozzle member 50 is positioned on the upper and lower open concave grooves 45 of the ring member 40, and each engagement protrusion 44 of the ring member 40 extends from each engagement part 35 a of the adapter 30. Engage with the second engaging groove 35b adjacent in the clockwise direction. When the ring member 40 is set at the permissible position, the nozzle member 50 can freely move the engaging protrusions 55 up and down in the concave grooves 45 (FIGS. 9 (A4), (A5), ( A4)) The nozzle member 50 can be pushed and operated without limit without rotating the ring member 40 stepwise. At this time, the character ∞ is displayed in each display window 36 of the adapter 30. In addition, the ring member 40 can be manually set to both by rotating forward and backward between the lock position and the allowable position.

  The engagement concave grooves 35b, 35b,... On the outer periphery of the intermediate cylinder 35 of the adapter 30 correspond to the lock position, the allowable position, and the indication position of the ring member 40 in order from the respective engagement portions 35a. Each engagement groove 35b can express a light click feeling each time the engagement protrusion 44 biased inward via the spring piece 44a is elastically engaged. On the other hand, the letters X and ∞ of each display window 36 indicate the lock position and the allowable position of the ring member 40, respectively, and the numeral 5 indicates the number of times of pressing the nozzle member 50 at the indicated position of the ring member 40, That is, the designated number of spraying operations by the nozzle member 50 is shown. Further, when the ring member 40 is manually set at the indicated position and the nozzle member 50 is pushed, the remaining number of spraying operations is sequentially displayed numerically on each display window 36 for each stroke of the pushing operation.

  FIG. 10 shows a series of changes in the relative positional relationship between the ring member 40 and the adapter 30 in accordance with the pushing operation of the nozzle member 50, that is, the spraying operation of the chemical liquid from the tip 52, as shown in FIG. In FIG. 10, the step rotation of the ring member 40 accompanying the pushing operation of the nozzle member 50 is illustrated as a relative movement path of the engaging protrusion 55 with respect to the ring member 40. Further, in the uppermost part of FIG. 10, numbers and characters displayed in each display window 36 are also illustrated as numbers 5, 4... 1, characters X, ∞ in a small horizontally long rectangular frame. .

  In the above description, the maximum number of pressing operations of the nozzle member 50 when the ring member 40 is manually set at the designated position, that is, the number of times of specifying the spraying operation is the first step for forming formed on the inner periphery of the ring member 40. This matches the number of sets of the second engagement pieces 41, 41,. Therefore, the designated number of times of the spraying operation by the nozzle member 50 can be arbitrarily changed by changing the number of sets of the first and second engaging pieces 41, 41,. In addition, on the inner periphery of the ring member 40, two sets of first and second engagement pieces 41, 41,..., 42, 42,. In this case, three or more sets of n sets may be arranged at equal intervals for each (1 / n) circumference, and at this time, the number of engagement protrusions 55 on the outer circumference of the nozzle member 50 is also n. Are arranged at equal intervals. However, n is an integer of 3 or more.

  The first and second engagement pieces 41, 42, the locking engagement piece 43, the engagement portion 35a, the engagement groove 35b, the spring piece 44a, the engagement protrusion 44, the engagement protrusion 55, etc. The series of related members may be changed to an arbitrary form other than the illustration as long as the respective functions can be achieved. Moreover, this may be omitted from the permissible position provided on the ring member 40.

  The present invention can be applied to a wide range of applications, for example, by spraying a medicinal solution whose dosage should be accurately controlled, such as a hair restorer or a pressure ulcer treatment.
