Description

  In the present invention, when an operation member such as a push button or a trigger lever is operated or the container is crushed, the contents of the container are provided, for example, from a spout provided in a push button of a pump device attached to the container or in the container itself. The present invention relates to an ejector for cosmetics and the like that spouts outward from a spout.

  Conventionally, in this type of ejector, for example, a pump type, as shown in FIG. 5, the pump device 2 is attached to the mouth portion of the container 1, and the press button 3 of the pump device 2 is pushed down to install the stem 4. By pushing, the pump device 2 was operated to pump up the contents 6 of the container 1 through the pipe 5 and ejected outward from the spout 8 at the tip of the bowl-shaped spout 7 of the push-down button 3.

  However, in such an ejector, for example, water enters from around the stem 4 and enters the container 1, contaminates the inside of the container 1, becomes moldy and unsanitary, and the contents are particularly rinsed or treated. In such a case, there is a risk that a jelly-like shape may cause a sucking failure due to clogging of the pipe 5, etc. In order to avoid such troubles, the pump device 2 is frequently removed from the container 1. There was a hassle that had to be cleaned.

  However, as shown in FIG. 6, even if the pump device 2 is removed and the container 1 is turned upside down, the jelly-like residual liquid 9 does not easily fall out of the container 1, for example, in the shoulder a of the container 1. In reality, the residual liquid adhering to the surface is difficult to clean even if a brush is rubbed through the mouth b.

In some conventional ejectors, for example, as shown in FIG. 7, the lid 1 a of the container 1 is separated by removing a screw so that it can be detached from the main body 1 b of the container 1 together with the pump device 2. . In such an ejector, by removing the lid 1a, the lid 1a and the main body 1b can be separated and washed separately.
Japanese Patent Laid-Open No. 11-208704

  However, even in such an ejector, since the bottom of the main body 1b is deep, it is difficult to completely remove the jelly-like residual liquid adhering to the bottom, and there is a problem that it cannot be cleaned cleanly.

  Accordingly, an object of the present invention is to provide an ejector that facilitates cleaning of a container.

  In order to achieve such an object, the present invention is characterized in that, in an ejector for ejecting the contents of a container from an upper ejection port to the outside, the container is composed of a main body portion and a detachable bottom portion. And

  And, for example, when refilling the container contents, remove the bottom from the main body of the container, divide the container, wash each separately, remove the residual liquid adhering to each inside, and then clean the container Fill with new contents.

  For example, a pump device having the jet port is attached to the mouth of the container, and the contents of the container are pumped up and ejected. Further, the bottom part can be attached to and detached from the main body part with screws. Of course, the present invention is not limited to screws, and for example, the contents may be prevented from being leaked by sandwiching packing or the like, and the bottom part may be detachable from the main body part by fitting.

  According to this invention, for example, at the time of refilling the contents of the container, the bottom is removed from the main body of the container, the container is divided and washed individually, and the residual liquid adhering to each inside is removed, and then the container is cleaned. Since the container is filled with new contents, the bottom can be cleaned cleanly, for example, because the bottom is shallow, and the shoulder of the main body can be cleaned cleanly by putting a brush etc. from the bottom. The container can always be kept hygienic for easy cleaning.

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.

  Reference numeral 10 in the figure denotes a container. As shown in FIG. 2, the container 10 is composed of a main body 11 and a bottom 12, and is made of plastic material into a whole bottle shape. The main body part 11 forms the mouth part 13 by squeezing the upper part of the cylindrical body, and the lower part opens straight. Male screws are provided on the outer peripheries of the mouth portion 13 and the lower opening 14, respectively. The bottom 12 is cup-shaped as shown in FIG. 2 and is provided with a female screw on the inner periphery of the upper opening 15. And the upper part of the bottom part 12 is screwed to the lower part of the main body part 11, and the bottom part 12 is detachably attached to the main body part 11 with a screw. As shown in FIG. Stores contents 16 such as rinses and treatments.

A pump device 20 is attached to the mouth portion 13 of such a container 10.
Although not shown, the pump device 20 is provided with a cylinder 21. A cylinder chamber is formed by inserting a piston into the cylinder 21, and a coil spring for returning the piston is housed in the cylinder chamber. A check valve is provided at the entrance of the chamber, and an open / close valve is provided at the exit.

  A suction pipe 22 is connected to the lower end of the cylinder 21 and extends downward from the cylinder 21. On the other hand, a screw cap 23 having a female screw on the inner periphery is attached to the upper end portion of the cylinder 21. A stem 24 integral with or connected to the piston protrudes upward from the central hole at the top of the screw cap 23. A push button 25 is attached to the upper end of the stem 24. The push button 25 is provided with a bowl-shaped jet pipe 27 having a jet port 26 at the tip.

  First, the tip of the suction pipe 22 is passed through the mouth portion 13 of the container 10, most of the cylinder 21 is placed in the container 10, the tip of the suction pipe 22 is extended to the vicinity of the bottom of the container 10, and the screw cap 23 is attached. It covers the mouth part 13 of the container 10 and is screwed to the mouth part 13, and a pump device 20 is attached to the mouth part 13 of the container 10 as shown in FIG. 1.

  When in use, the ejection pipe 27 is pointed at a target site such as a palm, the push button 25 is pushed down against the coil spring, the stem 24 is pushed in, the pressure in the cylinder chamber is increased by the piston, and the on-off valve is opened. The contents 16 are ejected from the stem 24 through the push button 25 to the outside through the ejection port 26.

  Then, when the contents 16 in the cylinder chamber disappear and the ejection of the contents 16 from the ejection port 26 stops, when the hand is released from the push button 25, the piston is pushed up by the biasing force of the coil spring to return the stem 24. To do. At this time, the on-off valve is closed as the piston is pushed up, the cylinder chamber is negatively pressured as the piston is pushed up, the check valve is opened, the contents 16 of the container 10 are sucked into the cylinder chamber through the sucking pipe 22, and Close the stop valve.

  By repeating this, the push button 25 is pushed down, and the contents 16 of the container 10 are pumped up by the pump device 20 and ejected from the upper ejection port 26 to the outside.

  By the way, in this kind of ejector, water etc. may enter into the container 10 with use, and mold may grow due to long-term use, or the contents of the container 10 may be altered and become, for example, jelly-like. Particularly in recent years, when the contents 16 of the container 10 disappear with use, the screw cap 23 is unscrewed from the mouth 13 and the pump device 20 is removed from the container 10 to fill the container 10 with the new contents 16. The number of refillable ones that are reused is increasing, and when the use is prolonged, there is a problem that the inside of the container 10 is contaminated and unsanitary or poorly sucked up.

  Therefore, in the illustrated ejector, when the pump device 20 is removed during refilling, the bottom 12 is unscrewed from the main body 11 of the container 10 and the bottom 12 is removed from the main body 11. For example, as shown in FIG. The jelly-like residual liquid 32 adhering to the bottom of the bottom portion 12 is removed by rubbing with a brush inserted from the upper opening 15 while applying water 31 from 30. For example, as shown in FIG. 4, the jelly-like residual liquid 34 attached to the shoulder portion 17 of the main body 11 is removed by rubbing with the tip of a brush 33 inserted from the lower opening 14.

  Thus, according to the ejector of the illustrated example, for example, when refilling the container contents, the bottom 12 is removed from the main body 11, the container 10 is divided, and the main body 11 and the bottom 12 are individually washed, After removing the residual liquids 32 and 34 adhering to the inside, the cleaned container 10 is filled with new contents 16. At this time, for example, since the bottom is shallow, the bottom part 12 can be cleaned cleanly, and a brush or the like can be inserted from the bottom part 12 side to clean the shoulder part 17 of the main body part 11 as well, so that the container 10 can be easily cleaned. As a result, the container 10 can be always kept hygienic.
