  Hereinafter, various forms of the present invention will be described in detail with reference to the drawings.

  1 and 2 are respectively a longitudinal sectional view showing a trigger type ejector 200 which is a reference technique of the present invention in a state where a slide member 150 described later is in a position where a total check amount is guaranteed, and a slide member 150 includes It is principal part sectional drawing shown in the state which exists in the position which restrict | limits the amount of checks, and FIG. 3 is a perspective view which shows the operation lever 140 and the slide member 150 which were provided in the trigger type ejector 200 from the back direction.

  In FIGS. 1 and 2, reference numeral 110 denotes an injection nozzle connected to a feed path 121 formed in the body 120 via a spin element 130. The injection nozzle 110 includes a nozzle base 111 attached to the spin element 130, a collision plate 112 attached to the tip of the nozzle base 111, and a lock portion that is integrally attached to the nozzle base 111 and prohibits the check of the operation lever 140 described later. 113.

  The nozzle base 111 has an opening 111 a that forms a swirl flow forming path and is connected to the swirl flow forming path. The impingement plate 112 forms a diffusion chamber 114 for diffusing the contents injected through the swirl flow forming path between the impingement plate 112 and an opening 112 a connected to the diffusion chamber 114.

  As a result, in the injection nozzle 110, after the contents swirling with the spin element 130 diffuse as spray particles in the diffusion chamber 114, a part of them collides with the back surface of the collision plate 112, and the diffusion chamber 114. The spray particles become finer particles and are agitated together with the air, so that they become bubbles in the diffusion chamber 114 and are ejected from the ejection holes 112a.

  As shown in FIG. 1, the body 120 includes a feed path 121 and a pump P that controls suction and pressurization of contents. The pump P includes a return spring 124 disposed between a cylinder 122 connected to the feeding path 121 through an opening 120a and a piston 123 slidable in the cylinder 122.

  Reference numeral 140 denotes an operation lever that is swingably held by a pin portion 120 p provided on the body 120, and a part of the rear surface thereof is always in contact with the piston 123. Thus, the pump P can suck and press the contents by the reaction force of the return spring 124 caused by checking the operation lever 140 and releasing it.

  Further, as shown in FIG. 3, three inner walls 142, 143, and 144 are integrally formed on the back surface 141 of the operation lever 140, and the open space defined by these inner walls has a longitudinal direction of the operation lever 140. The slide member 150 is provided so as to come into contact with the body 120 (cylinder 122) when the operation lever 140 is checked according to the amount of slide.

  As shown in FIG. 3, the slide member 150 has a contact portion 152 projecting toward the body 120 on the back surface 151 and a grip portion 153 used when the slide member 150 is slid. The slide member 150 is provided with a guide wall 154 that slides with respect to the inner wall 142 of the operation lever 140 on one side surface, and the other side surface is released to form an edge 150e. As a result, when the slide member 150 is attached from the back surface 141 of the operation lever 140, the back surface 151 of the slide member 150 is undercut fitted by the overhang portions 143p and 145 provided on the inner wall 143 of the operation lever 140. 150 is slidably held and fixed with respect to the operation lever 140.

  Although not shown, a positioning means Po for positioning the slide member 150 may be provided between the operation lever 140 and the slide member 150. The positioning means Po can be configured by providing a convex portion on one of the operation lever 140 and the slide member 150 and providing a concave portion into which the convex portion is fitted or a second convex portion that can be moved over. In this case, it is always possible to appropriately position the operation lever 140.

  On the other hand, a first check valve (elastic valve) 125 that is released by the check of the operation lever 140 is provided inside the feed path 121 connected by the cylinder 122 and the opening 120a and extending in the vertical direction, and the operation lever. An intake 127 having a second check valve (ball valve) 126 that is released by releasing the check 140 is provided. The intake 127 has an opening 127 a connected to the feed path 121 extending in the horizontal direction and an opening 127 b connected to the opening 120 a of the cylinder 122, and is undercut fitted near the lower end of the body 120.

  Reference numeral 160 denotes a base cap that is rotatably held with respect to the body 120 via the flange 127 f of the intake 127. The base cap 160 is a so-called screw cap, and fixes and holds the body 120 in the mouth portion 11 of the container.

  In other words, the trigger type ejector 200 includes a body 120 having a feed path 121 connected to the ejection nozzle 110 and having a pump P that controls suction and pressurization of contents, and is held by the body 120 so as to be swingable. An operation lever 140 that operates the pump P by dredging and release, a slide member 150 that slides the operation lever 140, and a base cap 160 that fixes and holds the body 120 to the mouth portion 11 of the container.

  According to the trigger type ejector 200, when the slide member 150 is slid to the vicinity of the lowest point of the operation lever 140 as shown in FIG. 1, the contact portion 152 of the slide member 150 causes the body when the operation lever 140 is checked. 120 (the opening edge 122e of the cylinder 122 in this reference technique) does not come into contact with the operation lever 140 when the injection nozzle 110 is rotated around the spin element 130 and the lock portion 113 is released from the opening edge 122e of the cylinder 120. All checks can be made without limiting the amount.

  In this case, the piston 123 is pushed into the cylinder 122 against the elastic force of the return spring 124 by all checks of the operation lever 140 to pressurize the contents in the cylinder 122 and feed it to the feed path 121 to inject it. The maximum amount of the foamed contents from 110 can be sprayed over a wide range, while the piston 123 is restored to the initial position by the elastic force of the return spring 124 by releasing the check of the operation lever 140 and the cylinder from the dip tube 128 to the cylinder. The contents can be sucked into 122.

  On the other hand, when the slide member 150 is slid toward the pin portion 120p as shown in FIG. 2, the contact portion 152 of the slide member 150 is aligned with the opening edge 122e of the cylinder 122, and the operation lever 140 is checked. At that time, since the contact with the opening edge 122e of the cylinder 122 occurs, the amount of check of the operation lever 140 is limited.

  According to such a configuration, the slide member 150 restricts the amount of check of the operation lever 140, thereby reducing the discharge amount of the content pumped from the cylinder 122 to the feed path 121 and the pressure thereof. Since the influence of the content colliding with the back surface is reduced, a small amount of foam-like content can be injected in a pinpoint manner to a specific location without spreading over a wide range.

  In the case of this reference technique, when the trigger type ejector 200 is not used, the injection nozzle 110 is rotated as shown in FIG. 1 so that the lock portion 113 is located between the operation lever 140 and the opening edge 122e of the cylinder 122. If the control lever 140 is disposed, the checking operation of the operation lever 140 is prohibited, so that erroneous injection when not in use can be prevented. In addition to the position shown in FIG. 1 described above, the position of the slide member 150 at the time of locking is not only the position shown in FIG. 2 but also the shape of the slide member 150 with a part of the contact portion 152 cut out and the guide wall 154 only on one side. With the above-described shape, the lock portion 113 can be disposed between the operation lever 140 and the opening edge 122e of the cylinder 122.

  On the other hand, FIGS. 4 and 5 are respectively a first embodiment of the present invention, which is a longitudinal sectional view and a perspective view for explaining the checking operation, and the same parts as those in the reference technique are described with the same reference numerals. Is omitted.

  In this embodiment, a rotation member 220 that rotates around the cylinder 122 is provided instead of the slide member 150. The rotating member 220 includes a rotating portion 221 that is rotatably held with respect to the outer peripheral surface of the cylinder 122, and an arm portion 222 that is provided integrally with the rotating portion 221.

  As shown in FIG. 5, the arm portion 222 has steps 223 and 224 in the vicinity of the tip, and the step 223 is in contact with the inner wall edge 140 e of the operation lever 140 and prohibits the check operation. On the other hand, the step 224 forms a contact portion that is located farther from the operation lever 140 than the step 223 and restricts the check of the operation lever 140. In addition, a grip portion 225 that is used when the rotation member 220 is rotated is provided at the lower end of the arm portion 222. Thereby, the rotation member 220 is held so as to be rotatable around the cylinder 122. In addition to holding the rotating member 220 so as to be rotatable around the cylinder 122, the concave-convex fitting portion described above (not shown) is provided between the rotating member 220 and the outer peripheral surface of the cylinder 122. Positioning means Po composed of first and second convex portions or protrusions and grooves capable of getting over is provided.

  According to such a configuration, when the trigger type ejector 100 is not used, the rotating member 220 is rotated to a position where the arm portion 222 enters the operation lever 140 and the lock portion 223 is moved to the position of the operation lever 140 as shown in FIG. If the inner wall edge 140e is brought into contact with the inner wall edge 140e, the check operation of the operation lever 140 is prohibited, so that erroneous injection when not in use can be prevented.

  And when it is in use, it can switch to two injection forms. For example, when it is desired to inject a small amount of content in a pinpoint manner focusing on a specific location, the rotation member 220 is introduced into an open space defined by the back surface 141 of the operation lever 140. If the position or contact portion (step) 224 is rotated to a position where it is aligned with the inner wall edge 140e of the operation lever 140, the lock portion 223 of the rotation member 220 is released, but the operation is performed when the operation lever 140 is checked. Since the inner wall edge 140e of the lever 140 contacts the contact portion 224, the amount of check of the operation lever 140 can be limited. Further, when it is desired to spread the maximum amount of contents over a wide range, the operation lever 140 can be operated by moving the contact portion 224 away from the operation lever 140 from the position shown in FIG. Since no contact is made with the contact portion 224 during the check-up, the check-up amount of the operation lever 140 can be reduced without restricting.

  In this embodiment, as shown in region A in FIG. 5, alignment marks that define the injection form are provided on the side surface of the rotating portion 221 of the rotating member 220 and the exterior surface of the cylinder 122. .

  FIG. 6 is a longitudinal sectional view showing a second embodiment of the present invention, and FIGS. 7 and 8 are perspective views for explaining the check operation of the embodiment. In the following description, the same parts as those in the first embodiment and the like are denoted by the same reference numerals and the description thereof is omitted.

  In this embodiment, a rotating member 230 that rotates between the injection nozzle 110 and the body 120 is provided instead of the rotating member 220. The rotating member 230 includes a rotating portion 231 that is fixed and held so as to be rotatable with respect to the spin element 130, and an arm portion 232 provided integrally with the rotating portion 231.

  As shown in FIGS. 7 and 8, the arm portion 232 has a back surface 232 e that is slidably in contact with the opening edge 122 e of the cylinder 122, while the front surface of the tip forms steps 233 and 234. Reference numeral 233 constitutes a lock portion that comes into contact with the inner wall edge 140e of the operation lever 140 and prohibits its check-in operation, while the step 234 is located farther from the operation lever 140 than the step 233 and the operation lever 140 The contact part which restricts check is comprised. Thereby, the rotation member 230 is rotatably held between the injection nozzle 110 and the body 120. In addition to the rotation member 230 being fixedly held between the injection nozzle 110 and the body 120 so as to be rotatable, the unevenness described above is not shown between the body 120 and the spin element 130. Positioning means Po including a fitting portion, first and second convex portions that can be crossed over, or a protrusion and a groove is provided.

  According to such a configuration, when the trigger type ejector 100 is not used, the rotating member 230 is rotated to a position where the arm portion 232 enters the operating lever 140 and the lock portion 233 is moved to the operating lever 140 as shown in FIG. If the inner wall edge 140e is brought into contact with the inner wall edge 140e, the check operation of the operation lever 140 is prohibited, so that erroneous injection when not in use can be prevented.

  And when it is in use, it can switch to two injection forms. For example, when it is desired to inject a small amount of contents in a pinpoint manner focusing on a specific location, the contact portion 234 aligns the rotating member 230 with the inner wall edge 140e of the operation lever 140 as shown in FIG. When the operation lever 140 is rotated to the position, the lock portion 233 of the rotation member 230 is released, but the inner wall edge 140e of the operation lever 140 contacts the contact portion 234 when the operation lever 140 is depressed. The amount of checks can be limited. Further, when it is desired to diffuse the maximum amount of contents over a wide range, the operation lever 140 can be operated by further rotating the rotation member 230 in the direction away from the operation lever 140 from the position shown in FIG. Since the operation lever 140 is not contacted with the contact portion 234 of the rotating member 230, the operation lever 140 can be fully checked without restricting the amount of check.

  In this embodiment as well, as shown in region A of FIGS. 7 and 8, the alignment mark that defines the injection mode is applied to the side surface of the rotating portion 231 of the rotating member 230 and the exterior surface of the body 120. ing. Moreover, although the rotation part 231 rotates with respect to the spin element 130, this may be fixedly held so that rotation around the body 120 adjacent to the injection nozzle 110 is possible.

  9 to 11 (a) and 9 (b) are a perspective view and an enlarged view of the main part of the third embodiment of the present invention, illustrating the checking operation, and the same parts as the other embodiments Are omitted with the same reference numerals.

  In this embodiment, instead of the rotating member 230, a rotating member 240 is provided integrally with the injection nozzle. The rotating member 240 includes a rotating part 241 that is fixed and held so as to be rotatable with respect to the spin element 130, and an arm part 242 provided integrally with the rotating part 241. The rotating unit 241 constitutes an injection nozzle having an internal structure similar to the above-described injection nozzle 110 (see the injection nozzle 110 and the like in FIG. 1) and an injection hole 240 a connected to the diffusion chamber 114. Accordingly, the rotating member 240 is held and fixed so as to be rotatable with respect to the spin element 130 by known means. The rotating member 240 is fixed and held so as to be rotatable between the rotating element 240 and the spin element 130, and the concave and convex fitting portion described above is not shown between the body 120 and the spin element 130. Positioning means Po composed of first and second convex portions or protrusions and grooves that can be climbed over is provided.

  The arm portion 242 includes a horizontal portion 242a extending toward the cylinder 122 and a cylinder contact portion 242b extending from the horizontal portion 242a along the periphery of the rotating portion 241. The cylinder contact portion 242b is bounded by the horizontal portion 242a. Is provided with a lock portion 243 that is in contact with the inner wall edge 140e of the operation lever 140 and prohibits its check-down operation, and has an operation lever having a step difference lower than that of the lock portion 243 near the tip of the cylinder contact portion 242b. The contact part 244 which restrict | limits the amount of checks of 140 is provided. Note that the back surface 242e of the cylinder contact portion 242b is located at the position where the lock portion 243 or the contact portion 244 contacts the inner wall edge 140e of the operation lever 140, as shown in the enlarged side view of FIGS. Slidably contacts the opening edge 122e.

  According to such a configuration, when the trigger type ejector 100 is not used, the rotation member 240 is rotated to a position where the lock portion 243 is aligned with the inner wall edge 140e of the operation lever 14 as shown in FIG. 9B. If the lock portion 243 is brought into contact with the inner wall edge 140e of the operation lever 140, the check operation of the operation lever 140 is prohibited, so that erroneous injection when not in use can be prevented.

  And when it is in use, it can switch to two injection forms. For example, when it is desired to inject a small amount of contents in a pinpoint manner focusing on a specific location, the contact portion 244 of the rotating member 240 is aligned with the inner wall edge 140e of the operation lever 140 as shown in FIG. When the operation lever 140 is rotated to the position, the lock portion 243 of the rotation member 240 is released, but when the operation lever 140 is depressed, the inner wall edge 140e of the operation lever 140 is contacted with the contact portion 244 of the rotation member 240 with a stroke L1. Therefore, the amount of check of the operation lever 140 can be limited. If the maximum amount of contents is to be diffused over a wide range, the operation lever 140 can be moved to the position shown in FIG. Since no contact is made with the contact portion 244 of the rotating member 240 at the time of checking, it is possible to check all with the stroke L2 without limiting the amount of checking of the operation lever 140.

  In particular, in the case of this embodiment, since the rotation member 240 is a rotation member that is rotatably held and fixed integrally with the injection nozzle, existing parts other than the rotation member 240 can be used.

  12 and 13 are perspective views showing modifications of the third embodiment, and the same parts as those of the other embodiments are denoted by the same reference numerals and the description thereof is omitted.

  In this embodiment, the rotation member 250 provided integrally with the injection nozzle includes a rotation part 251 that is fixed and held so as to be rotatable with respect to the spin element 130, and an arm provided integrally with the rotation part 251. Part 252. The rotating part 251 constitutes an injection nozzle having an injection hole 250a connected to the same internal structure as the injection nozzle 110 described above. Accordingly, the rotating member 250 is also held and fixed so as to be rotatable with respect to the spin element 130 by known means. The rotating member 250 is also fixed and held so as to be rotatable between the rotating element 250 and the spin element 130. In addition, although not shown, the uneven fitting described above is provided between the body 120 and the spin element 130. Positioning means Po comprising a part, a first and second convex part that can be crossed over, or a protrusion and a groove is provided.

  As shown in FIGS. 12 and 13, the arm portion 252 has a front end back surface 252 e slidably contacting the opening edge 122 e of the cylinder 122, while its front end front surface forms steps 253 and 254. Reference numeral 253 constitutes a lock portion that comes into contact with the inner wall edge 140e of the operation lever 140 and prohibits the check operation, while the step 254 is located farther from the operation lever 140 than the step 253 and The contact part which restricts check is comprised.

  According to such a configuration, when the trigger type ejector 100 is not used, the lock member 253 is rotated to a position where the lock portion 253 is aligned with the inner wall edge 140e of the operation lever 140 as shown in FIG. If 253 is brought into contact with the inner wall edge 140e of the operation lever 140, the check-down operation of the operation lever 140 is prohibited, so that erroneous injection when not in use can be prevented.

  And when it is in use, it can switch to two injection forms. For example, when it is desired to inject a small amount of contents in a pinpoint manner focusing on a specific location, the contact portion 254 of the rotating member 250 is aligned with the inner wall edge 140e of the operation lever 140 as shown in FIG. If it is rotated to the position, the lock portion 253 of the rotation member 250 is released, but the inner wall edge 140e of the operation lever 140 contacts the contact portion 254 of the rotation member 250 when the operation lever 140 is depressed. Therefore, the amount of check of the operation lever 140 can be limited. Further, when it is desired to diffuse the maximum amount of contents over a wide range, if the contact portion 254 is further rotated away from the operation lever 140 from the position of FIG. Since it does not come into contact with the contact portion 254 of the rotating member 250 at the time of checking, it is possible to check all of the operation lever 140 without limiting the amount of checking.

  In this embodiment as well, as shown in region A of FIGS. 12 and 13, alignment marks that define the injection mode are applied to the side surface of the rotating portion 251 of the rotating member 250 and the exterior surface of the body 120. Has been.

  As described above, according to the present invention, the trigger type ejector 100 is provided with switching means for switching the amount of check of the operation lever 140 to limit the amount of ejected contents and changing the injection range. The amount of discharge of the content pumped from the cylinder 122 to the feed path 121 and the pressure thereof are reduced, and the influence of the content colliding against the back surface of the collision plate 112 is reduced. Without being diffused over a wide range, it is possible to inject in a pinpoint manner to a specific location.

  In particular, since the switching means has contact portions (224, 234, 244, 254) of the rotating members (220-250) between the operation lever 140 and the body 120, the rotating members (220- The contact part (224, 234, 244, 254) of 250) does not hinder the user's checking operation, and the effect of excellent operability is obtained.

  The above description shows only various forms of the present invention, and those skilled in the art can make various modifications within the scope of the claims. For example, the pump P provided in the body 120 is not limited to those illustrated in the above-described embodiments and the like as long as the check of the operation lever 140 and the release thereof directly affect the injection amount. . Further, the amount of check of the operating lever can be switched between two or more by providing a step in the contact portion of the rotating member, and the positioning at that time also includes the clearance of the positioning means Po and the number of grooves. Can be increased.
