(First embodiment)
Hereinafter, the sprayer according to the first embodiment will be described with reference to FIGS.

As shown in FIG. 1 and FIG. 2, the housing 11 of the sprayer is configured by detachably connecting a bottomed and covered cylindrical upper case 13 to an upper end opening of a bottomed cylindrical lower case 12.

The bottom end of the regulator 15 is fixed to the bottom 14 of the upper case 13 in a penetrating state. A sharp tubular needle member 17 is held in a central hole (not shown) of the regulator 15.

On the outer periphery of the regulator 15, a support cylinder portion 18 projects downward from the bottom portion 14, and on the outer periphery of the support cylinder portion 18, a holding case 19 having a bottomed cylindrical shape as a cylinder housing portion is formed. The opening is fixed via a screw.

In the holding case 19, a gas cylinder 22 as a gas cylinder is stored in a state where it is received at the bottom of the holding case 19. The tip of the needle member 17 is pierced through the upper lid 23 of the gas cylinder 22. For this reason, the carbon dioxide gas in the gas cylinder 22 reaches the needle member 17. A seal 24 is provided on the upper surface of the upper cover 23 of the gas cylinder 22 to prevent gas leakage from between the upper cover 23 and the needle member 17.

A container accommodating portion 30 is formed in the lower case 12 adjacent to the holding case 19. A lotion container 31 as a liquid container is detachably installed in the container accommodating portion 30, and the lotion is accommodated therein. A tube 32 for passing the lotion to be sucked up is connected to the upper end of the lotion container 31. In addition, a small hole (not shown) is provided in the upper end portion of the lotion container 31 in order to prevent the inside of the lotion container 31 from becoming negative pressure due to the suction of the lotion.

As shown in FIGS. 2 and 3, a valve case 41 constituting an on-off valve is connected to the upper portion of the regulator 15. A connecting pipe 42 projects from the valve case 41. The connecting pipe 42 communicates with the internal passage of the needle member 17 via a valve case 41 and a passage (not shown) in the regulator 15.

The spray port 51 that opens toward the outside is fixed to the side wall of the upper case 13. A nozzle 52 constituting a spray mechanism is fitted in the base end portion of the spray port 51. The connecting pipe 42 is connected to the base end portion of the nozzle 52. A supply port 43 constituting a spray mechanism is fixed through the lower peripheral wall of the spray port 51. The tube 32 is connected to the proximal end of the spray port 51. The tip opening of the nozzle 52 is disposed close to the tip opening of the supply port 43. When gas is ejected from the nozzle 52 at a high speed, the vicinity of the tip opening of the supply port 43 becomes negative pressure, and the lotion in the lotion container 31 is sucked up. For this reason, the skin lotion becomes mist and is ejected from the opening of the spray port 51 together with the jet of carbon dioxide.

An operation knob 61 as an operation unit is provided at the upper end of the upper case 13. By operating the operation knob 61 so as to be pushed down, a valve (not shown) in the valve case 41 is pushed down via an elevating rod (not shown), and the passage between the needle member 17 and the nozzle 52 is performed. Is released. For this reason, the carbon dioxide gas in the gas cylinder 22 connected to the primary side of the valve case 41 is supplied to the nozzle 52 through the passage and the connecting pipe 42.

In the first embodiment, the holding case 19 and the lotion container 31 are juxtaposed in the lower case 12. Therefore, the gas cylinder 22 and the lotion container 31 are arranged close to each other. Further, the valve, a contact portion between the valve and the operation knob 61 via the lifting rod, and the holding case 19 are arranged on one axis extending along the vertical direction.

Next, the operation of the sprayer according to the first embodiment will be described.

In this sprayer, the holding case 19 and the gas cylinder 22, and the container housing part 30 and the lotion container 31 are arranged in close proximity to each other. Therefore, the sprayer has a small outer shape as a whole, and has a simple cylindrical shape that is long in the vertical direction. For this reason, the nebulizer does not get in the way and is convenient to carry.

When using the sprayer, the valve is opened by pushing down the operation knob 61 with an index finger or the like while holding the housing 11 with one hand. At this time, the mist of the skin lotion is ejected from the spray port 51 on the carbon dioxide jet. Therefore, this mist and carbon dioxide can be applied to the skin.

For this reason, the following effects can be obtained by the sprayer of the first embodiment.

(1) In the sprayer according to the first embodiment, the holding case 19 and the lotion container 31 are juxtaposed. Therefore, although the sprayer is equipped with the gas cylinder 22 and the lotion container 31, the whole sprayer is a simple cylinder shape and is compact. For this reason, this sprayer is not bulky and is convenient to carry and easy to hold. Therefore, this nebulizer can be easily used for makeup on the road.

(2) The spray mechanism including the spray port 51 is disposed at the upper end of the housing 11, the holding case 19 is disposed at the lower part of the spray mechanism, and the lotion container 31 is disposed below the spray port 51 and the supply port 43. Has been placed. Therefore, the entire sprayer can be elongated to a shape suitable for carrying and gripping.

(3) Since the operation knob 61 for opening and closing the spray mechanism is provided at the upper end of the housing 11, the operation knob 61 can be easily pushed down with the index finger of one hand while the housing 11 is held with one hand. Therefore, since the spraying operation of the sprayer can be easily performed with one hand, other cosmetic tools can be handled with the remaining one hand.

(4) A spray port 51 that opens to the outside of the housing 11 is fixed to the inside of the housing 11, and a nozzle 52 and a supply port 43 are fixed to the spray port 51. Therefore, the nozzle 52 and the supply port 43 can be unitized. Therefore, it is possible to contribute to the compactness of the sprayer, and replacement is easy when the nozzle 52 is clogged, for example.

(5) The valve, the holding case 19 of the gas cylinder 22, and the contact portion between the valve and the operation knob 61 are arranged on one axis. Therefore, the whole sprayer can be made long and compact. Therefore, the sprayer is convenient to carry and hold.

(Second Embodiment)
Next, a sprayer according to a second embodiment will be described with reference to FIGS.

Also in 2nd Embodiment, the housing 11 of the sprayer is provided with the lower case 12 and the upper case 13 similarly to 1st Embodiment. In the second embodiment, in order to detachably connect the upper case 13 to the lower case 12, the structure shown in FIG. 7 is employed.

A protrusion 71 extending downward is formed at the bottom 14 of the upper case 13. In the protrusion 71, a pair of hooked portions 72 each having a hook shape protrude in a direction away from each other at locations facing each other across the axis L <b> 1 of the upper case 13 and the lower case 12. . A base 70 is fixed to the bottom 16 of the lower case 12, and a connection release button 73 is slidably attached to the base 70 along the vertical direction. A pair of levers 74 extending in the vertical direction are supported by a shaft 75 so as to be tiltable at locations facing each other across the axis L <b> 1 inside the lower case 12. At the upper end portion of each lever 74, a locking portion 76 that protrudes toward each other is formed. Both locking portions 76 are locked and detached from the locked portion 72 as the lever 74 tilts. An arm portion 77 extending toward the opposing lever 74 is formed at the lower end portion of each lever 74. A spring 78 such as a coil spring is interposed between the distal ends of both arm portions 77 in a compressed state. The levers 74 are biased by the springs 78 so that the locking portions 76 are locked to the locked portions 72. The connection release button 73 has a pair of pressing portions 79 protruding upward. These pressing portions 79 are in contact with the tip portions of the both arm portions 77 from below.

Also in the second embodiment, the lower end portion of the regulator 15 is fixed to the bottom portion 14 of the upper case 13 as in the first embodiment. However, in the second embodiment, as shown in FIG. 4, the holding case 19 is not disposed below the regulator 15 in the housing 11. In the second embodiment, instead of the holding case 19, a part of the space in the housing 11 acts as a cylinder accommodating portion 81 for accommodating the gas cylinder 22. A male screw 82 is formed on the outer peripheral surface of the upper end portion of the gas cylinder 22. The gas cylinder 22 is detachably attached to the regulator 15 by the male screw 82 being screwed into a female screw 83 formed at the lower end of the regulator 15. These gas cylinders 22 and the regulator 15 are disposed on the same axis L2. The valve case 41 constituting the on-off valve is disposed at a location deviated from the axis L2, in this case, on the side of the regulator 15.

4 and 5, the nozzle case 52 and the spray port 51 are fixed to the valve case 41, and the regulator 15, the valve case 41, the nozzle 52, and the spray port 51 are unitized.

A cylindrical adherend 84 having both upper and lower ends opened is inserted into the lower peripheral wall of the spray port 51 and fixed to the spray port 51. In the adherend portion 84, the portion extending into the spray port 51 is formed in a tapered shape so that the diameter becomes smaller toward the upper side. And the front-end | tip part of the supply port 43 is inserted with respect to the to-be-adhered part 84 so that extraction from the downward direction is possible.

The upper end of the tube 32 is connected to the base end of the supply port 43, and the lower end of the tube 32 is connected to the lotion container 31. This is the same as in the first embodiment.

The base end of the supply port 43 and the entire tube 32 are covered with a tube cover 85. The tube cover 85 extends upward from a cap 86 attached to the upper end of the lotion container 31. The lotion container 31, the tube 32, the cap 86, the tube cover 85, and the supply port 43 are assembled together to form a container unit 87.

A pair of protrusions 88 are formed on the side wall of the skin lotion container 31 at positions facing each other across an axis (not shown) of the skin lotion container 31. Further, elastic pieces 89 are respectively formed at locations (not shown) covered by the lower case 12 at the lower end portion of the upper case 13 and corresponding to both the protrusions 88. The positions of the protrusions 88 and the elastic pieces 89 are set such that the protrusions 88 and the elastic pieces 89 are engaged with each other in a state where the supply port 43 is inserted into the adherend portion 84.

As shown in FIG. 6, in the bottom 16 of the lower case 12, a mounting portion 91 having a double cylindrical shape with an open upper end is projected upward at a location below the container housing portion 30. . A non-solid elastic member 92 formed of an elastic material such as rubber is inserted into the mounting portion 91 from above and mounted on the mounting portion 91. The elastic member 92 is disposed in a state of being elastically deformed between the bottom 16 of the lower case 12 and the lotion container 31. The skin lotion container 31 is received from the lower side by the elastic member 92 that is elastically deformed.

A hole 93 for communicating the inside and outside of the lotion container 31 is formed in a part of the upper wall portion of the lotion container 31. A waterproof and moisture permeable filter 94 that closes the hole 93 is attached to the upper wall portion of the lotion container 31. The filter 94 is formed of, for example, a polyurethane film having a large number of fine pores smaller than water molecules and larger than water vapor.

Other configurations are the same as those in the first embodiment. For this reason, the same elements as those described in the first embodiment are denoted by the same reference numerals, and redundant description is omitted.

Next, the operation of the sprayer according to the second embodiment will be described.

In this sprayer, the valve case 41 is arranged at a location deviated from the gas cylinder 22 accommodated in the cylinder accommodating portion 81 and the axis L2 of the regulator 15. For this reason, compared with the sprayer with which the valve case 41 is arrange | positioned on the same axis L2 as the gas cylinder 22, the dimension of the sprayer about the direction of the axis L2 becomes short.

On the other hand, with the arrangement of the valve case 41, the size of the sprayer in the direction orthogonal to the axis L2 increases. However, since the sprayer of the second embodiment does not include the holding case 19, the lotion container 31 can be disposed close to the gas cylinder 22 by the thickness of the holding case 19. From this, an increase in the size of the sprayer in the direction orthogonal to the axis L2 due to the arrangement of the valve case 41 is suppressed. Therefore, the sprayer is small as a whole, and is convenient for carrying without being in the way.

As shown in FIG. 7, in the sprayer, when the connection release button 73 is not operated, both arm portions 77 are urged by springs 78 in a direction away from each other. This urging force is transmitted to both locking portions 76 via both levers 74, and each locking portion 76 is locked to the locked portion 72. Therefore, the upper case 13 is connected to the lower case 12, and the upper case 13 is not easily detached from the lower case 12.

Further, at this time, the container unit 87 is received from the lower side by the elastic member 92 which is elastically deformed. Thereby, unnecessary movement of the container unit 87, for example, rattling, is regulated.

Furthermore, since the connection release button 73 is disposed on the bottom 16 of the lower case 12, it is less likely to be accidentally pressed than when the connection release button 73 is disposed elsewhere.

The sprayer is operated by pushing down the operation knob 61 with an index finger or the like while holding the housing 11 with one hand as in the first embodiment. By this depression, the valve is opened, carbon dioxide gas is supplied to the nozzle 52, and the mist of the skin lotion is ejected from the spray port 51 on the carbon dioxide gas jet. Therefore, this mist and carbon dioxide can be applied to the skin.

When replacing at least one of the container unit 87 and the gas cylinder 22 or when cleaning the tip opening of the supply port 43, the connection release button 73 is operated to be pressed with, for example, a finger. By this connection release button 73, a force for pushing up the arm portion 77 acts on each arm portion 77. By this force, both levers 74 tilt about the shaft 75 as a fulcrum so that both arm portions 77 approach each other against the spring 78. Due to this tilting, both locking portions 76 are displaced in directions away from each other, and are disengaged from the corresponding locked portions 72. Thereby, the connection state with respect to the lower case 12 of the upper case 13 is cancelled | released. Therefore, the upper case 13 can be removed from the lower case 12.

When the upper case 13 is removed from the lower case 12, the container unit 87 and the gas cylinder 22 assembled in the upper case 13 are extracted from the container accommodating portion 30 and the cylinder accommodating portion 81 of the lower case 12. Further, when both the elastic pieces 89 of the upper case 13 are elastically deformed to release the engagement state of the two protrusions 88 with respect to the elastic piece 89, the container unit 87 is removed from the upper case 13. Moreover, the gas cylinder 22 is removed from the regulator 15 by rotating the gas cylinder 22 previously assembled to the regulator 15 around the axis L2 in a direction in which the female screw 83 and the male screw 82 are tightened.

Subsequently, the new container unit 87 can be inserted from below into the upper case 13 removed from the lower case 12 so that the supply port 43 enters the adherend portion 84. In the middle of the insertion, the projection 88 abuts on the elastic piece 89 and elastically deforms the elastic piece 89 outward. When the supply port 43 enters the adherend portion 84, the protrusion 88 faces the elastic piece 89, and each protrusion 88 engages with the corresponding elastic piece 89 by the elastic restoring force of the elastic piece 89. Further, the new gas cylinder 22 is rotated around the axis L <b> 2 in the direction in which the female screw 83 and the male screw 82 are tightened, whereby the gas cylinder 22 is attached to the regulator 15.

In this way, a new container unit 87 and gas cylinder 22 are mounted on the upper case 13.

By operating the connection release button 73 to be pressed, the interval between the both locking portions 76 is expanded. In this state, the container unit 87 is disposed in the container accommodating portion 30 of the lower case 12, and the gas cylinder 22 is disposed in the cylinder accommodating portion 81 of the lower case 12.

At this time, the elastic member 92 is pressed by the lotion container 31 of the container unit 87 and is elastically deformed between the bottom 16 of the lower case 12 and the lotion container 31. The container unit 87 is received from below by the elastic member 92.

Then, when the upper case 13 is put on the lower case 12, the finger is released from the connection release button 73. At this time, the elastic restoring force of the spring 78 causes the levers 74 to tilt with the shaft 75 as a fulcrum in the direction in which the distance between the arms 77 increases, and the locking portions 76 engage with the corresponding locked portions 72. . By these engagements, the upper case 13 is connected to the lower case 12. Further, when both levers 74 tilt in a direction in which the distance between both arm portions 77 increases, the connection release button 73 is pushed down and returned to the original position before the pressing operation.

As described above, when the lotion container 31 is replaced, the entire container unit 87 is replaced. For this reason, when the lotion container 31 is replaced with a lotion container 31 containing a different type of lotion, the lotion before the replacement hardly remains in the tube 32 or the supply port 43. .

When the container unit 87 is removed from the upper case 13, the supply port 43 can be cleaned through the front end opening using a cleaning tool because the front end opening of the supply port 43 appears.

By the way, while carrying the sprayer, the internal pressure of the lotion container 31 may increase due to an increase in temperature or the like. Depending on the position of the sprayer, for example, when the sprayer is arranged sideways, the skin lotion in the skin lotion container 31 is pushed out through the tube 32 by the internal pressure of the skin lotion container 31 thus raised, and is supplied from the supply port 43. There is a risk of leakage.

In this respect, in the second embodiment, the hole 93 formed in a part of the upper wall portion of the lotion container 31 is closed by the waterproof / breathable filter 94. For this reason, even if the temperature inside the lotion container 31 increases as the temperature rises, the air in the lotion container 31 is released to the outside of the lotion container 31 through the filter 94. Phenomenon that the internal pressure of the high becomes difficult to occur. Thereby, the leak of the lotion through the tube 32 and the supply port 43 by the raise of the internal pressure of the lotion container 31 is suppressed.

Therefore, according to the second embodiment, the following effects can be obtained in addition to the same effects as the effects (1) to (3) described above.

(6) The cylinder accommodating part 81, the gas cylinder 22 and the regulator 15 are arranged on the same axis L2, and the valve case 41 is arranged at a position deviated from the axis L2. For this reason, the size of the sprayer in the direction of the axis L2 can be made shorter than that in the first embodiment, and the entire sprayer can be made compact.

(7) Instead of the holding case 19, a part of the housing 11 (the space below the regulator 15) acts as the cylinder accommodating portion 81. The upper end of the gas cylinder 22 is directly attached to and supported by the regulator 15 with a screw. Since the sprayer does not include the holding case 19, the sprayer can be configured with a small number of parts. Further, the skin lotion container 31 can be arranged close to the gas cylinder 22 by the thickness of the holding case 19. With the above arrangement of the valve case 41, it is possible to suppress an increase in the size of the sprayer in the direction orthogonal to the axis L2.

(8) The lotion container 31, the tube 32, the cap 86, the tube cover 85, and the supply port 43 constitute a container unit 87 by being assembled with each other. For this reason, when the lotion container 31 is replaced with a lotion container 31 containing different types of lotions, the entire container unit 87 can be replaced. Thereby, it can suppress that old and new lotion mixes in the inside of the tube 32, or the inside of the supply port 43. FIG.

Moreover, the supply port 43 can be extracted from the spray port 51 by removing the container unit 87 from the upper case 13. Therefore, even if the supply port 43 is clogged, the clogging can be eliminated by extracting the supply port 43 and cleaning it. Further, by assembling a new container unit 87 to the upper case 13 without performing the above-described cleaning, the clogged supply port 43 can be replaced with a clogged supply port 43.

(9) The regulator 15, the valve case 41, the spray port 51, and the nozzle 52 are assembled to the housing 11 in a united state.

Therefore, the above-mentioned plurality of members can be handled as one assembly, and it becomes easy to handle.

(10) In the bottom 16 of the lower case 12, an elastic member 92 is disposed at a location below the container housing portion 30. For this reason, the lotion container 31 can be received from the lower side by the elastic member 92, and unnecessary movement of the lotion container 31 can be suppressed. In addition, dimensional errors in the direction of the axis L1 of the housing 11, the gas cylinder 22 and the axis L2 of the regulator 15 can be absorbed by elastic deformation of the elastic member 92, and the dimensional management of the product can be facilitated.

Further, a non-solid elastic member 92 is inserted into the double cylindrical mounting portion 91. Therefore, the elastic member 92 can be elastically deformed in the space in the mounting portion 91, and the elastic member 92 can be prevented from being contracted due to the elastic deformation.

(11) A hole 93 is formed in a part of the upper wall portion of the lotion container 31, and the hole 93 is closed with a waterproof and moisture-permeable filter 94. For this reason, the air in the lotion container 31 can escape to the outside of the lotion container 31 through the filter 94 and the hole 93. Therefore, even if the temperature inside the lotion container 31 increases as the temperature rises, the increase in the internal pressure of the lotion container 31 is suppressed, and leakage of the lotion from the tube 32, the supply port 43, etc. is suppressed. be able to.
(Example of change)
Each of the above embodiments can be modified and embodied as follows.

· A cover that can move between a position covering the opening of the spray port 51 and a position retracting from the position may be provided outside the upper case 13.

As an example of such a cover, a two-dot chain line in FIG. The cover 101 is formed with a communication hole 102 that opens and closes the opening of the spray port 51 as the cover 101 moves up and down. When the cover 101 is moved up and down to a position where the communication hole 102 faces the opening, the opening is opened. When the cover 101 is moved up and down to a position where the communication hole 102 is shifted upward or downward from the opening, the opening is closed by the cover 101.

Therefore, when the sprayer is not used, the opening of the spray port 51 is closed by the cover 101, so that the entry of foreign matters such as dust into the spray port 51 can be regulated. Moreover, the mist of the skin lotion can be ejected by opening the opening of the spray port 51 when using the sprayer.

The cover 101 may be formed such that its surface does not protrude from the surface of the lower case 12. That is, the surface of the cover 101 and the surface of the lower case 12 may be formed on the same plane. In this case, no step is generated between the cover 101 and the housing 11.

Further, the communication hole 102 may be changed to a notch.

· A cleaning mechanism for cleaning the inside of the supply port 43 may be provided above the supply port 43.

The two-dot chain line in FIG. 5 shows an example of the cleaning mechanism. The cleaning mechanism includes a brush 103 disposed above the supply port 43. The brush 103 includes a handle 104 that extends along the vertical direction and penetrates the upper peripheral wall of the spray port 51, and a plurality of hairs 105 that are planted in a bundled state at the lower end of the handle 104. . The brush 103 is preferably configured to move up and down in conjunction with the up and down movement of the upper case 13. The interlocking of the brush 103 here means that the hair 105 enters the supply port 43 when the upper case 13 is moved downward and put on the lower case 12. When the upper case 13 is moved upward, the hair 105 is withdrawn from the supply port 43.

In this way, by moving the upper case 13 downward with respect to the lower case 12, the hair 105 can be inserted into the supply port 43 and the lotion clogged inside the supply port 43 can be removed. . In this case, it is not necessary to remove the container unit 87 from the upper case 13 in order to eliminate clogging.

For example, when the upper case 13 is moved downward and is covered on the lower case 12, the operation knob 61 is locked so as not to operate. When the upper case 13 is moved upward, the lock is released and the operation knob 61 can be operated. This mechanism can be realized by, for example, a cam mechanism, a link mechanism, or a combination thereof.

In this way, for example, when the sprayer is carried in a bag or the like, even if the operation knob 61 is touched by putting a hand in the bag and trying to find something, the operation knob 61 is pressed. It is possible to prevent the carbon dioxide gas from being injected by being operated.

The sprayer may be applied to a sprayer in which a liquid of a type different from lotion is contained in a liquid container, or a sprayer in which a gas different from carbon dioxide gas is injected into a gas cylinder 22 in a compressed state.

In the housing 11, other members may be added to the lower case 12 and the upper case 13.

-The supply port 43 and the tube 32 may be assembled into a unit by assembling the spray port 51, and the lotion container 31 may be detachably attached to the tube 32 of this unit.

In order to detachably connect the upper case 13 to the lower case 12, a structure different from that of the second embodiment may be adopted.

8 to 11 show an example of this structure. As shown in FIG. 8, the upper case 13 has an adherend portion 111 formed in a substantially cylindrical shape at the lower portion thereof. When the upper case 13 is connected to the lower case 12 of FIG. 9, the upper portion of the lower case 12 is put on the adherend portion 111. As shown in FIG. 11, a pair of levers 112 (only one of which is shown in FIG. 11) is tilted by the shaft 113 at locations opposite to each other across the axis (not shown) of the upper case 13 in the adherend portion 111. Supported as possible. At the lower end portion of each lever 112, a claw portion 114 that protrudes and protrudes from the adherend portion 111 as it tilts is formed. Each lever 112 is urged by a spring 115 such as a coil spring in a direction in which the claw portion 114 protrudes from the adherend portion 111.

As shown in FIG. 9, a pair of engaging portions 116 each including a concave portion or a hole are formed at a position where the upper portion of the lower case 12 is aligned with the claw portion 114 when being covered with the adherend portion 111. Yes. The upper case 13 is connected to the lower case 12 by projecting both the claw portions 114 from the adherend portion 111 and entering the corresponding engaging portions 116. Further, both the claw portions 114 are immersed in the adherend portions 111 and come out of the corresponding engaging portions 116, whereby the connection state of the upper case 13 to the lower case 12 is released.

8 and 10, a connection release button 117 is disposed on the side of the upper case 13 and below the spray port 51 so as to be movable in the radial direction of the housing 11. A transmission mechanism 118 that transmits the movement of the connection release button 117 to both levers 112 and tilts the lever 112 is disposed between the connection release button 117 and the both levers 112. The transmission mechanism 118 includes a slide member 119 that slides along the radial direction of the housing 11 in conjunction with the connection release button 117, a pair of arm portions 121 formed on the upper portions of both levers 112, the slide member 119, and the lever. And an elevating member 122 disposed between the upper and lower portions 112 so as to be movable up and down. The slide member 119 is formed with an inclined surface 119 a that contacts the elevating member 122.

According to the above configuration, when the connection release button 117 is pressed as shown by an arrow A1 in FIGS. 10 and 11, the slide member 119 slides so as to approach the axis of the housing 11 as shown by an arrow A2. To do. By this sliding, the elevating member 122 is raised along the slope 119a of the slide member 119 as indicated by an arrow A3. At this time, the elevating member 122 acts on the lever 112 via the arm portion 121, and the lever 112 resists the spring 115 and tilts about the shaft 113 as a fulcrum. With this tilting, the claw portion 114 of each lever 112 is immersed in the adherend portion 111 and comes out of the engaging portion 116. Therefore, the upper case 13 and the lower case 12 can be separated.

In addition, when the pressing of the release button 117 is stopped while the lower case 12 is attached to the attachment portion 111, each lever 112 is attached to the claw portion 114 by the elastic restoring force of each spring 115. Tilts so as to protrude from the portion 111, and the claw portion 114 of each lever 112 enters the engaging portion 116 and engages. By these engagements, the upper case 13 is connected to the lower case 12. At this time, the tilt of each lever 112 is transmitted to the elevating member 122 through the arm portion 121, and the elevating member 122 is lowered. The slide member 119 slides away from the axis of the housing 11 by the descending lift member 122, and the connection release button 117 is pushed back to the position before the press in conjunction with this.
