By repeating the check and release of the check The present invention relates to a trigger type ejector having an operation lever for driving a pump and ejecting the contents of a container from a nozzle.

The applicant of the present application provides a novel trigger-type ejector with a stopper that prevents the operation lever from being checked on a nozzle that can rotate with respect to the body, and further, a long groove is formed on the back surface of the operation lever. Has been proposed (see, for example, Patent Literature 1). )
Japanese Patent Laid-Open No. 2004-329991 (FIG. 1, FIG. 2, etc.)

  Such a conventional trigger type ejector is effective in preventing the user from unexpectedly ejecting the contents since the check is prevented even if the operation lever is accidentally checked when not in use. Since the amount of squirting can be adjusted as appropriate according to the user's request, it is also effective in improving usability when taking out the contents.

  For this reason, the inventor of the present application hopes that the checking operation of the operation lever becomes easy while maintaining the function of preventing the user from unexpectedly ejecting the contents and the function of adjusting the ejection amount. Only when this is done, it has been recognized that an appropriate amount of contents according to the user's request can be reliably taken out, and that a user-friendly trigger type ejector can be provided for taking out the contents.

  The present invention has been made on the basis of such fact recognition. The purpose of the present invention is to take out an appropriate amount of contents stepwise and reliably according to a user's request only when desired. It is also possible to provide a trigger type ejector that is easy to use for taking out the contents.

The present invention includes a body having a pump that sucks and pumps the contents of a container and is provided with a nozzle at the tip, and is rotatably held by the body. By repeating the check and release of the check A trigger type ejector for ejecting the contents of the container from the nozzle, wherein the operation lever includes a lever main body portion that is rotatably held with respect to the body; A grip part that can be pushed in and pulled out along the lever main body part, and the grip part checks the operation lever when the operating lever is pressed with the grip part pushed in. The amount is regulated by contact with the body, and a check amount adjustment piece that does not contact the body when the operation lever is checked by pulling out the gripping portion is provided, and the nozzle is arranged around the ejection axis of the contents Times A possible arm portion, the arm portion is provided with a stopper for preventing the牽曳as contact with the operating lever and the牽曳amount adjusting pieces by rotating the nozzle, the牽曳amount adjusting piece, It has a base portion extending from both sides of the grip portion toward the body, and is a bridge portion that connects the two base portions to each other .

  In this invention, it is preferable that a lever main-body part is provided with the protrusion which penetrates the opening part provided in the holding part and is exposed from the said opening part.

  According to the present invention, when the contents are not desired to be taken out when not in use, the grip portion is pushed along the lever main body portion of the operation lever toward the rotation center of the operation lever (lever main body portion), and then is inserted into the nozzle. The provided arm portion is rotated around the ejection axis of the contents toward the operation lever. Thereby, since the stopper with which an arm part is provided is arrange | positioned in the position which contacts a check amount adjustment piece, the check as an operation lever can be blocked | prevented.

  On the other hand, when the user wants to take out the contents, the stopper is placed in a position where it does not come into contact with the check amount adjustment piece by rotating the arm part away from the control lever. become.

  At this time, since the gripping part is pushed toward the rotation center of the operation lever (lever body part), the range in which the operation lever can be checked is that the check amount adjustment piece is the same as the body. It is restricted to the range until contact. That is, even if the user checks the operating lever to the full, the amount of checking is not the original maximum checking amount of the operating lever, so the ejection amount from the nozzle does not become the maximum ejection amount. Can be suppressed to a constant value.

  On the other hand, if the grip part is pulled out along the lever main body of the operation lever in a direction away from the rotation center of the operation lever (lever main body), even if the operation lever is depressed, the check amount adjustment piece Will not come into contact with the body. In other words, if the user checks the operating lever to the full, the amount of checking is the original maximum checking amount of the operating lever, so the amount of ejection from the nozzle is also the maximum amount of ejection, and the amount of ejection from the nozzle is maximized. Can be raised to value.

  Moreover, when the gripping part is pulled out, the entire operation lever is extended, and the length from the pivot center of the lever body part to the end of the gripping part, that is, the length from the pivot center as the whole operation lever to the terminal of the gripping part. Is extended.

  That is, by pulling out the grip of the operation lever along the lever main body, it is possible to check the operation lever as much as possible, and the length of the operation lever is extended, which is necessary for its rotation. The check force is also relatively small.

  Therefore, according to the present invention, only when desired, an appropriate amount of contents according to the user's request can be taken out in a stepwise and reliable manner. Can be provided.

Further, in the present invention, the check amount adjustment piece has a base portion extending from both sides of the grip portion toward the body, and is a bridge portion connecting the two base portions. By increasing the strength of the piece, even if the operation lever is restrained relatively strongly, the restraining can be effectively prevented. Further, in the case of such a configuration, even if variations occur when the lever main body, the gripping part, or the like is assembled, there is no malfunction such as the check amount adjustment piece not contacting the body when the operation lever is checked.

  Further, in the present invention, if the lever main body part is provided with a protruding piece that penetrates the opening provided in the gripping part and is exposed from the opening, it is possible to visually check the position of pushing and pulling out of the gripping part. Easy to use when taking out the contents.

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

It is a longitudinal cross-sectional view which shows the mass sprayable state of the sprayer 100, and its spray state.

  Reference numeral 110 denotes a body attached to the mouth of the container 20 via a ring cap C. As shown in FIG. 2 and the like, the body 110 is provided with a pump P having a feeding path 111 for sucking and pumping contents. The pump P includes a return spring 114 disposed between a cylinder 112 communicating with the feeding path 111 through an opening 110a and a piston 113 slidable in the cylinder 112.

  Further, an intake 116 having a dip tube 115 depending on the inside of the container 20 is disposed inside the body 110. Two holes 116 a and 116 b are formed in the intake 116, and the inside of the intake 116 forms a part of the feeding path 111.

  Inside the intake 116 are a suction valve (ball valve) 117 released by the negative pressure generated in the pump P, and a discharge valve (elastic valve) 118 released by the pressure of the contents pumped from the pump P. And are arranged.

  Reference numeral 120 denotes an injection nozzle connected to a feed path 111 formed in the body 110 via a spin element 130. The injection nozzle 120 includes a nozzle base 121 attached to the spin element 130, a collision plate 122 attached to the tip of the nozzle base 121, and a nozzle cover 123 attached integrally to the nozzle base 121.

  The nozzle cover 123 integrally has an arm portion 123a that can rotate around the ejection axis O of the contents (see FIG. 2). The arm portion 123a includes a stopper 123s that rotates the entire nozzle 120 via the nozzle cover 123 to contact a check amount adjustment piece 142c described later to prevent check as the operation lever 140.

  Reference numeral 140 denotes an operation lever that is rotatably held by the body 110 and drives the pump P by repeating the check and release of the check.

  The operation lever 140 is pushed into the lever main body 141 along the longitudinal direction of the lever main body 141 and the lever main body 141 that is rotatably held by the pin portions 110p provided on the left and right sides of the body 110. And a gripping portion 142 that can be pulled out.

  On the rear side of the lever main body 141, a pressing piece 141a extending toward the piston 113 is integrally formed. The pressing piece 141a is always in contact with the piston 113 regardless of the amount of rotation of the lever main body 141. Thereby, the pump P can repeat the pushing operation of the piston 113 by the check of the operation lever 140 and the return operation of the piston 113 by the elastic force of the return spring 114 when the check is released. Suction and pumping are possible.

  On the other hand, the gripping portion 142 includes a front wall 142a and two side walls 142b that surround the front surface and the left and right side surfaces of the lever main body portion 141 from the outside.

  The side wall 142b of the gripping part 142 extends rearward toward the body 110, and when the operating lever 140 is pressed with the gripping part 142 pushed in, the amount of checking is reduced by the body 110 (this embodiment). Then, a check amount adjusting piece 142c that is regulated by contact with the tip of the cylinder 112 is integrally formed. The check amount adjustment piece 142c is disposed at a position where the grip portion 142 does not come into contact with the body 110 when the grip portion 142 is pulled out of the lever main body 141 and the operation lever 140 is checked.

  The check amount adjustment piece 142c has two protrusions extending from both sides of the grip portion 142 toward the body 110.

  The pushing and pulling of the grip portion 142 is regulated by, for example, a fixing means F described below.

  First, as shown in FIG. 4 and the like, the lever main body portion 141 is integrally formed with an engaging convex portion 141p that extends outward from the side surface 141b. The engaging convex portions 141p are formed at two locations, upper and lower, with a pair of left and right sides as a set, spaced apart along the longitudinal direction of the lever main body 141. Each of the left and right pairs of engaging projections 141p is one component of the fixing means F.

  On the other hand, the gripping portion 142 is integrally formed with an engagement recess 142n that is recessed toward the inside in the vicinity of the upper end of the side surface 142b. The engaging recess 142n detachably engages the protrusion 141p of the lever main body 141 with a pair of left and right as a set. Each of the engaging recesses 142n, which is a pair of left and right, is the other component of the fixing means F.

That is, according to the fixing means F of the present reference technique , the engaging protrusion 141p formed on the lever main body 141 is fitted into the engaging concave 142n formed on the gripping part 142, so that Thus, the grip portion 142 can be fixed at a predetermined push-in position and a pull-out position.

  Further, according to such a configuration, of the two convex portions 141p, the convex portion 141p formed on the side closer to the pin portion 110p is not used when the content is not taken out, or when the content is taken out. Therefore, when spraying only a small amount of the contents, it is used to fix the gripping part 142 to the lever main body part 141, and the convex part 141p formed on the side far from the pin part 110p It is used for fixing the gripping part 142 to the lever main body part 141 when the contents are sprayed and when the contents are sprayed in large quantities.

According to the present reference technique , when the contents are not desired to be taken out when not in use, the grip 142 is moved along the lever main body 141 of the operation lever 140 as shown in FIGS. ) After pushing in toward the rotation center of 140, that is, the pin portion 110p, the arm portion 123a provided on the nozzle 120 is rotated around the ejection axis O of the contents toward the operation lever 140. Accordingly, the stopper 123s provided in the arm portion 123a is disposed at a position where it comes into contact with the check amount adjustment piece 142c, so that check as the operation lever 140 can be prevented.

  On the other hand, when the user wants to take out the contents, as shown in FIG. 3, by rotating the arm portion 123a away from the operation lever 140, the stopper 123s is disposed at a position where it does not come into contact with the check amount adjusting piece 142c. Therefore, the operation lever 140 can be checked.

  At this time, since the gripping portion 142 is pushed toward the pin portion 110p, the range in which the operation lever 140 can be checked is as shown in FIG. 3B. The range until the piece 142c comes into contact with the body 110 is restricted. That is, even if the user checks the operating lever 140 to the full, the amount of checking is not the original maximum checking amount of the operating lever 140, so the amount of ejection from the nozzle 120 does not become the maximum amount of ejection. The amount of ejection from the nozzle 120 can be suppressed to a constant value.

  On the other hand, as shown in FIG. 4, if the gripping part 142 is pulled out along the lever main body part 141 of the operation lever 140 in a direction away from the pin part 110p, the check lever The amount adjusting piece 142c does not come into contact with the body 110. That is, if the user checks the operating lever 140 to the full, the checking amount is the original maximum checking amount of the operating lever 140, so the ejection amount from the nozzle 120 also becomes the maximum ejection amount. The ejection amount can be increased to the maximum value.

  Moreover, if the gripping portion 142 is pulled out, the entire operation lever 140 is extended, and the length from the pin portion 110p to the end of the gripping portion 142, that is, the length from the pin portion 110p as the entire operation lever 140 to the end of the gripping portion 142. Is extended.

  That is, by pulling out the grip portion 142 of the operation lever 140 along the lever main body portion 141, the operation lever 140 can be checked to the maximum, and the length of the operation lever 140 is extended. The check force required for rotation is relatively small.

Therefore, according to the present reference technique , an appropriate amount of contents according to the user's request can be taken out stepwise and reliably only when desired, and the trigger type is convenient for taking out the contents. An ejector can be provided.

  In taking out the contents, the nozzle cover 123 has an opening 121a formed between the spin element 130 and the swirl flow forming path, so that the injection nozzle 120 Then, after the contents swirling with the spin element 130 diffuse in the diffusion chamber 124 as spray particles, some of them collide with the rear surface of the collision plate 122, and the spray particles in the diffusion chamber 124 become finer. Since the particles are stirred together with the air, they are bubbled in the diffusion chamber 124 and injected from the injection hole 122a. Further, the ejection form from the nozzle 120 may be a mist form in addition to the foam form.

In addition, since the check amount adjustment piece 142c of the present reference technology is a protrusion that extends from both sides of the gripping portion 142 toward the body 110, the contact with the body 110 can be made evenly on the left and right. Even if the check is relatively strong, the check can be effectively prevented.
