  However, with such an ejector, when the contents of the container disappears with use, the contents suddenly stop coming out of the outlet without any sign, especially when a spare ejector is not prepared. There were also problems.

  Accordingly, an object of the present invention is to provide a pump-type ejection device or ejector that prevents the contents of a container from suddenly disappearing during use.

  In order to achieve such an object, the invention according to claim 1 is a pump-type ejection device that attaches to the mouth of a container, sucks the contents of the container using a suction pipe, and injects the contents from the ejection port to the outside. A fitting member with a groove that allows air to flow into the suction pipe when the remaining contents of the container are reduced is fitted to the tip of the suction pipe.

  And when the contents of the container are reduced with use, the liquid level of the contents of the container is lowered and the air in the container flows into the suction pipe through the groove and changes the sound generated during use, or The user is informed that the contents of the container are low because the injection pattern of the contents to be injected from the outlet is changed or both of them are changed.

  In order to achieve the above-mentioned object, the invention according to claim 2 is a pump-type jet which is similarly attached to the mouth of the container, sucks up the contents of the container using a suction pipe, and injects it outward from the jet outlet. In the apparatus, a fitting member having a first end portion having a long fitting length and a second end portion having a short fitting length communicating with each other is provided, and the first end portion or the second end portion of the fitting member is connected to the suction pipe. It is characterized in that it is flipped over to the tip of the lip so that it can be replaced.

  At first, the first end having a long fitting length is fitted to the tip of the suction pipe, and the second end having a short fitting length is extended from the tip of the suction pipe. When the remaining amount is low, the liquid level of the contents of the container will drop and the contents will not come out from the spout. Detach, remove the fitting member, reverse and replace it, fit the second end with a short fitting length to the tip of the suction pipe, and attach the first end with the long fitting length from the tip of the suction pipe By extending, the ejection device is attached to the mouth of the container again, and the remaining contents can be sucked to the end through the suction pipe.

  In order to achieve the above-mentioned object, the invention according to claim 3 is a pump-type jet which is also attached to the mouth of the container, sucks up the contents of the container using a suction pipe, and injects it from the jet outlet to the outside. The apparatus is characterized in that the suction pipe can be bent so as to be bent back.

  First, when the suction pipe is bent greatly and used, and the remaining contents of the container become small with use, the liquid level of the contents of the container will drop and the contents will not come out from the spout. Inform the user that the remaining amount is low, and then remove the jetting device from the container and bend the suction pipe back to eliminate or reduce the bending, so that the jetting device is attached to the mouth of the container again. The remaining contents can be sucked to the end through the suction pipe.

  In order to achieve the above-mentioned object, the invention according to claim 4 is a pump-type jet which is similarly attached to the mouth of the container, sucks up the contents of the container using a suction pipe, and injects it outward from the jet outlet. The apparatus is characterized in that the length up to the tip of the suction pipe is freely changeable.

  And at first, the length up to the tip of the suction pipe is shortened, and when the contents of the container are reduced with use, the liquid level of the contents of the container is lowered and the contents do not come out from the spout Therefore, the user is informed that the contents are low, and at that time, once the spray device is removed from the container and the length up to the tip of the suction pipe is increased, the liquid is sprayed to the mouth of the container again. Install the device and allow the remaining contents to be sucked to the end through the suction pipe.

  In order to achieve the above-mentioned object, the invention described in claim 5 is an ejector, and is characterized by including the pump-type ejection device according to any one of claims 1 to 4.

  Then, as described above, the user is informed in advance that the contents of the container are low.

  According to the present invention, when the contents of the container are reduced with use, the user is notified in advance, so that when the user replenishes the contents, the contents to be replenished are prepared in advance and a new ejector is provided. When using, a new ejector can be prepared in advance, and the risk of inconvenience due to sudden disappearance of the contents of the container during use can be eliminated.

  According to the first aspect of the present invention, when the contents of the container are low, the sound generated during use is changed, or the injection pattern of the contents injected from the outlet is changed, or those Since both are changed, the fact is notified, so that it is not necessary to remove the ejection device from the container to perform any work, and it can be used continuously until the contents are completely removed.

  According to the second to fourth aspects of the present invention, when the content of the container is low, the liquid level of the content of the container is lowered and the content does not come out from the spout. It can be clearly recognized, and at that time, by removing the ejection device from the container and performing a simple operation, it can be used again until the contents are completely removed.

The best mode for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 shows a longitudinal section of a reciprocating pump type ejector according to the present invention.

  The illustrated ejector is used for shampooing, shampooing, cosmetics, medicinal use, and the like, and has an ejection device 12 attached to the mouth 10a of a plastic container 10 having a bottle shape. Although the container 10 is provided with a male screw on the outer periphery of the mouth portion 10a and is not shown in the figure, in this example, the cosmetic liquid is stored as the contents.

The pump-type ejection device 12 is screwed into the mouth portion 10a of the container 10.
The pump type ejection device 12 is provided with a cylinder 14. The cylinder 14 is provided with a flange 14a at the upper end, and several steps are provided in the middle, and are formed concentrically and gradually decreasing in diameter downward. Slightly below the flange 14a, a vent hole 14b is opened through in the radial direction.

  In such a cylinder 14, a ball-like check valve 15 is placed from above and placed on the tapered portion 14 c, followed by inserting a coil spring 16, and then a piston 17 having a longitudinal groove 17 a is placed thereon. It is inserted together with the on-off valve 18 attached to the outer periphery. Then, an annular plate-shaped packing 19 is overlaid on the lower surface of the flange 14a.

  Then, a screw cap 21 that is press-fitted into the cylindrical screw cover 20 is attached so as to cover the flange 14, and a guide cylinder portion 21 a that protrudes downward from the center of the screw cap 21 is inserted into the cylinder 14, and the on-off valve 18 is moved from above. The pressure chamber A is pressed and pressed against the piston 17 to slightly depress the piston 17 against the urging force of the coil spring 16, thereby forming a pressure chamber A in the cylinder 14.

  Then, the stem 22 is inserted into the guide tube portion 21 a of the screw cap 21 from above, the tip of the piston 17 is fitted into the lower end portion thereof, and the upper end portion projects upward from the screw cap 21. An injection button 23 is attached to the tip of the stem 22. The injection button 23 is provided with a nozzle member 24 in a lateral direction, and the injection port 24a of the nozzle member 24 and the inside of the stem 22 are communicated with each other via an internal injection passage 23a.

  Then, the upper end portion of the suction pipe 26 is press-fitted into the lower end portion of the cylinder 14 having a small diameter. A fitting member 30 is fitted to the lower end portion of the suction pipe 26. Further, the overcap 27 is covered with the spray button 23 and attached to the outer periphery of the screw cap 21.

  Then, the cylinder 14 together with the suction pipe 26 is put into the container 10 from the mouth portion 10a, the tip of the suction pipe 26 is extended toward the bottom portion, the fitting member 30 is close to the bottom portion, and the screw cap is attached to the mouth portion 10a. The flange 14a of the cylinder 14 is sandwiched with the packing 19 between the screw cap 21 and the mouth portion 10a.

  Now, when using this ejector now, the overcap 27 is removed from the screw cap 21. Then, the user pushes the injection button 23 down to push the stem 22 and push the piston 17 together against the urging force of the coil spring 16. Then, the opening / closing valve 18 does not move at first and opens between the piston 17 and communicates between the pressurizing chamber A and the stem 22 through the vertical groove 17 a of the piston 17 from between the piston 17 and the opening / closing valve 18.

  Then, as the piston 17 is pushed in, the pressure in the pressurizing chamber A is increased, and the contents of the pressurizing chamber A are ejected from the inside of the stem 22 to the outside through the ejection passage 23a of the ejection button 23.

  At this time, the opening / closing valve 18 is also pushed down with a slight delay as the stem 22 is pushed, and when the opening / closing valve 18 crosses the vent hole 14b, the passage between the injection button 23 and the screw cap 21 and between the screw cap 21 and the stem 22 is passed. The outside and the inside of the container 10 are communicated through the pores 14b, and the inside of the container 10 is set to atmospheric pressure.

  After the injection, when the hand is released from the injection button 23, the stem 22 is pushed up together with the piston 17 based on the urging force of the coil spring 16, the gap between the on-off valve 18 and the piston 17 is closed again, and the pressure in the pressurizing chamber A is reduced. Then, the check valve 15 is opened, and the contents of the container 10 are sucked into the pressurizing chamber A through the suction pipe 26.

  By repeating the above, the contents of the container 10 are sequentially sucked into the pressurizing chamber A by using the suction pipe 26, and the contents of the pressurizing chamber A are opened by the opening / closing valve 18 and the injection button 23 through the ejection passage 23a. It injects toward the exterior from the jet nozzle 24a of the nozzle member 24. FIG.

  As shown in FIG. 2, the fitting member 30 has a cylindrical shape, is provided with a partition wall 31 in the middle of the interior, has a vertical cross section, and has a communication hole 32 in the center of the partition wall 31. Further, an axial longitudinal groove 34 is formed from the inlet to the partition wall 31 on the inner periphery on the one end 33 side. Such a fitting member 30 is formed by press-fitting the tip of the suction pipe 26 into the one end 33 side and attaching to the tip of the suction pipe 26.

  Then, when the content of the container 10 is reduced with use, the liquid level of the content of the container 10 is lowered to be lower than the position AA, so that the air in the container 10 passes through the longitudinal groove 34 and enters the suction pipe 26. The content of the container 10 remains little because it changes the suction sound generated during use, or changes the injection pattern of the content injected from the outlet 24a, or both of them change. Inform the user that it has become.

  Thereby, the user can prepare the contents to be replenished in advance when replenishing the contents, and can prepare a new ejector in advance when using a new ejector. Can eliminate the risk of sudden inconvenience.

  In addition, when the contents of the container are low, from changing the sound generated during use, or from changing the injection pattern of the contents injected from the outlet, or from both of them, Since the fact is notified, it is not necessary to remove the ejection device from the container and perform any work, and it can be used continuously until the contents are completely eliminated.

  In the above-described example, the case where the grooved fitting member 30 that allows air to flow into the suction pipe 26 when the contents of the container 10 remain at the tip of the suction pipe 26 has been described has been described. However, for example, as shown in FIG. 3, a fitting member 40 having a first end portion 36 having a long fitting length and a second end portion 37 having a short fitting length communicated with each other is provided. The end portion 36 or the second end portion 37 may be reversed to the tip of the suction pipe 26 so that it can be replaced.

  The fitting member 40 shown in FIG. 3 also has a cylindrical shape, is provided with a partition wall 38 in the middle of the inside and has a vertical section H shape, and a communication hole 39 is formed in the center of the partition wall 38 to form a first end 36 and a second end. 37 communicate with each other. In the illustrated example, several ribs 41 extending in the radial direction are formed on the front and back of the partition wall 38. And the fitting length of the 1st end part 36 is set to L1, and the fitting length of the 2nd end part 37 is set to L2 shorter than it.

  First, the tip end of the suction pipe 26 is press-fitted into the first end portion 36, and the first end portion 36 having a long fitting length is fitted to the tip end of the suction pipe 26. The second end 37 having a short fitting length is extended, and the fitting member 40 is attached to the tip of the suction pipe 26. When the use is started in that state, and the content of the container 10 is reduced with use, the liquid level of the content of the container 10 is lowered and the content does not come out from the spout 24a. Inform the user that the remaining is low.

  At that time, the ejection device 12 is once removed from the container 10, the fitting member 40 is removed and reversed to replace it, and the second end portion 37 having a short fitting length is fitted to the tip of the suction pipe 26 to suck up the suction pipe 26. By extending the first end portion 36 having a long fitting length from the tip of the pipe 26, the tip of the first end portion 36 is extended to the vicinity of the bottom of the container 10 from before, and the ejection device 12 is again applied to the mouth 10a of the container 10. And the remaining contents can be sucked to the end through the suction pipe 26.

  Even if it does in this way, a user will prepare the contents to be replenished beforehand when there is a notice that the contents have become small because the contents no longer come out from the spout 24a. When a new ejector is used, a new ejector can be prepared in advance, and the content of the container 10 can be suddenly lost during use, thereby eliminating the inconvenience.

  Further, in the above-described example, the fitting members 30 and 40 are fitted to the tip of the suction pipe 26. However, the suction pipe 26 itself may be bent so that it can be bent back without using the fitting member. Good. For example, as shown in FIG. 4A, a bellows portion 43 is provided on a part of the suction pipe 26, or the suction pipe 26 is made of a soft material as shown in FIG. It can be bent back and forth.

  At first, the suction pipe 26 is used by being largely bent as shown in (C), and when the content of the container 10 is reduced with use, the liquid level of the content of the container 10 is lowered and the discharge port 24a Since the contents no longer appear, the user is informed that the contents are remaining. At that time, once the ejection device 12 is removed from the container 10, the suction pipe 26 is bent back, the bending is eliminated, and straightening or bending is reduced as shown in (A) and (B), The tip of the suction pipe 26 is brought closer to the bottom of the container 10 than before, and the ejection device 12 is attached again to the mouth 10a of the container 10 so that the remaining contents can be sucked to the end through the suction pipe 26.

  Even if it does in this way, a user will prepare the contents to be replenished beforehand when there is a notice that the contents have become small because the contents no longer come out from the spout 24a. When using a new ejector, a new ejector can be prepared in advance, and the risk of inconvenience due to sudden disappearance of the contents of the container 10 during use can be eliminated.

  As another means, the length to the tip of the suction pipe 26 may be changeable. For example, as shown in FIG. 5, a plurality of pipes 26 a and 26 b are connected in a nested manner to form the suction pipe 26 so that it can be stretched and the length to the tip of the suction pipe 26 can be changed.

  At first, for example, the pipe 26b is pushed into the double pipe 26a to shorten the length of the suction pipe 26, and the length up to the tip is shortened. With use, the contents of the container 10 are reduced. At this time, the liquid level of the contents of the container 10 is lowered, and the contents are no longer discharged from the ejection port 24a, so that the user is informed that the contents are remaining. At that time, the ejection device 12 is once removed from the container 10, the pipe 26 b is pulled out from the pipe 26 a, and the length to the tip of the suction pipe 26 is lengthened, so that the ejection device 12 is again attached to the mouth 10 a of the container 10. The remaining contents can be sucked up through the suction pipe 26 after installation.

  Even if it does in this way, a user will prepare the contents to be replenished beforehand when there is a notice that the contents have become small because the contents no longer come out from the spout 24a, When a new ejector is used, a new ejector can be prepared in advance, and the content of the container 10 can be suddenly lost during use, thereby eliminating the inconvenience.

  Of course, instead of increasing the length of the suction pipe 26 itself, when there is a notification, for example, by pulling out the suction pipe 26 from the cylinder 14, the length to the tip of the suction pipe 26 is increased. Then, the tip of the suction pipe 26 may be brought closer to the bottom of the container 10.

It is a longitudinal cross-sectional view of the reciprocating pump type ejector by this invention. It is an expanded longitudinal cross-sectional view of the front-end | tip part of the suction pipe. It is an expanded longitudinal cross-sectional view of the front-end | tip part of the suction pipe which is another example. Furthermore, the tip part of the suction pipe which is another example is shown, (A) is a case where a bellows part is provided in a part of the suction pipe, (B) is a case where the suction pipe is made of a soft material, (C) FIG. 2 is a partial external view of a state in which a suction pipe is bent. It is the fragmentary longitudinal cross-section of the suction pipe which is still another example.
