Description

The present invention relates to, for example, a volatilizer for volatilizing a chemical solution containing an aromatic component or a deodorant component.

A volatilizer for volatilizing a chemical solution containing an aromatic component or a deodorant component is shipped with the container containing the chemical solution sealed in order to prevent the problem that the chemical solution starts to volatilize in an unused state. .. Then, when starting to use the volatilizer, the user opens the container and partially immerses the liquid absorbing member in the chemical solution. As a result, the chemical solution is sucked up through the liquid absorbing member and volatilization is started.

As an example, the volatilizer has a container containing a chemical solution and a shielding member that closes the opening of the container. The shielding member is formed in a bottomed tubular shape, and is attached to the opening of the container with the bottom immersed in the chemical solution. A pushing member is inserted and arranged in the shielding member. The pushing member has a protrusion at its tip for penetrating the bottom of the shielding member. Further, the pushing member holds the liquid absorbing member and has a hole at the tip for allowing the chemical solution to permeate the liquid absorbing member.

When using this volatilizer, the user pushes the pushing member holding the liquid absorbing member into the shielding member to destroy the bottom of the shielding member. As a result, the chemical solution flows into the inside of the shielding member, and the chemical solution permeates the liquid absorbing member through the hole of the pushing member. The chemical solution is sucked up by the liquid absorbing member and volatilized.

Japanese Unexamined Patent Publication No. 2004-230146

In the above-mentioned conventional volatilizer, the bottom of the shielding member is destroyed by the protrusion provided at the tip of the pushing member. Therefore, even if the pushing member is pushed until the protrusion is brought into contact with the bottom of the container, at least the height of the protrusion is reached. The liquid absorbing member and the bottom of the container are separated by the amount. In other words, since the conventional volatilizer described above has a protrusion at the tip of the pushing member, the liquid absorbing member held by the pushing member cannot be brought into contact with the bottom of the container. Therefore, in the above-mentioned conventional volatilizer, all the chemicals in the container cannot be sucked up by the liquid absorbing member, and the chemicals remaining at the bottom of the container are wasted.

The present invention has been made in view of the above points, and an object of the present invention is to provide a volatilizer capable of volatilizing a chemical solution without waste.

One aspect of the volatilization apparatus of the present invention is a container containing a chemical solution, a tubular body having a lower end located inside the container and an upper end opened at the upper part of the container, a lid closing the lower end of the tubular body, and a container. It has a liquid absorbing member to vaporize siphoned a chemical inside, and pushing member which is disposed inside the cylindrical body to hold the liquid absorbing member. The pushing member includes a rupture claw that pushes a part of the lid to separate it from the lower end of the tubular body at least partially, and a lid locking portion that locks the open lid in an open state at the lower end. .. With the lid opened by the pushing member, the lower end of the liquid absorbing member protrudes from the lower end of the pushing member and comes into contact with the bottom of the container.

According to one aspect of the present invention, the chemical solution can be volatilized without waste.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an external view of the volatilizer 10 according to the first embodiment. The volatilizer 10 has a container 2 (FIG. 2), an inner plug 4 (FIGS. 3 and 4), a liquid absorbing member 6 (FIG. 5), a pushing member 8 (FIG. 6), and a cover 9 (FIG. 1). The container 2, the inner plug 4, the pushing member 8, and the cover 9 are made of resin, and the liquid absorbing member 6 is made of non-woven fabric. The volatilizer 10 is configured by combining these plurality of members 2, 4, 6, 8 and 9.

As shown in FIG. 2, the container 2 is a bottomed substantially cylindrical body 21 for accommodating a chemical solution (not shown) containing an aromatic component and a deodorant component, and a body projecting above the body 21. A so-called bottle container integrally having a substantially cylindrical neck portion 22 having a diameter smaller than that of the portion 21, and a substantially annular shoulder portion 23 that is slightly inclined upward from the upper end of the body portion 21 toward the lower end of the neck portion 22 and is continuous. Is. The body portion 21 has an outer shape in which a cylinder is gently converged toward the bottom portion, and has a shape in which the back surface side is flattened. A circular opening 24 is formed inside the upper end 22a of the neck portion 22, and an annular ridge 25 for fixing the inner plug 4 is integrally projected on the outer circumference of the neck portion 22. The ridge 25 does not necessarily have to be annular, and may be replaced with, for example, a screw thread.

On the outer surface side between the upper end of the body portion 21 and the outer circumference of the shoulder portion 23, a substantially annular convex portion (not shown) and a substantially annular step for fitting the lower end edge 91 of the cover 9 described later. A section 26 is provided. By fitting the lower end edge 91 of the cover 9 to the step portion 26 and fitting the cover 9 to the container 2, as shown in FIG. 1, the outer surface of the volatilizer 10 becomes a smooth surface with no steps as a whole. Become. The cover 9 is formed in a tubular shape having an outer shape that gently converges from the lower end edge 91 toward the upper end opening 92, and has a shape in which the back surface side is flattened like the body portion 21. Further, the cover 9 has a plurality of volatilization holes 93 on each of the front side and the back side thereof. The shape and size of the volatilization hole 93 can be arbitrarily set.

FIG. 3 is an external view of the inner plug 4, and FIG. 4 is a vertical cross-sectional view of the inner plug 4 bisected along the center line. As shown in FIGS. 3 and 4, the inner plug 4 includes a substantially cylindrical tubular body 41, a substantially hemispherical lid body 42 in which the axial lower end 41a of the tubular body 41 is closed in a sealed state, and a substantially hemispherical lid body 42. The upper end 41b of the tubular body 41 is integrally provided with an annular folded portion 43 that is continuously folded outward. The tubular body 41 has an outer diameter slightly smaller than the inner diameter of the opening 24 of the container 2, and is inserted and arranged through the opening 24 so that the lower end 41a thereof is positioned in the container 2. Therefore, the lid body 42 is arranged at a position where it is immersed in the chemical solution contained in the container 2.

An annular thick portion 44 (see FIG. 4) that slightly bulges inward is provided on the inner surface side of the tubular body 41 near the lower end 41a. The thick portion 44 gently swells toward the lower end 41a of the tubular body 41 so as to gradually reduce the inner diameter of the tubular body 41. That is, the inner diameter of the tubular body 41 is gradually reduced toward the lower end 41a at the portion of the thick portion 44. By providing the thick portion 44, the mechanical strength near the lower end of the tubular body 41 is increased. As a result, when the lid 42 is separated from the tubular body 41 as described later, when a large force is applied near the lower end 41a of the tubular body 41, the tubular body 41 is elastically deformed and stretched. It is possible to suppress defects and ensure the separation of the lid 42. Further, the inner diameter of the portion of the tubular body 41 above the thick portion 44 may be gradually reduced toward the thick portion 44. In this case, the push-in cylinder 81 can be easily inserted into the tubular body 41 of the inner plug 4 fixed to the container 2 at the time of assembling the volatilizer 10 described later.

The lid 42 is provided continuously inside the thick portion 44 of the lower end 41a of the tubular body 41 and integrally with the tubular body 41. An annular flange portion 45 is provided on the outer periphery of the lid body 42, and the lid body 42 is connected to the lower end 41a of the tubular body 41 via the flange portion 45. An annular thin portion 46 for separating the lid body 42 is provided between the flange portion 45 and the inner surface of the thick portion 44. The thin portion 46 is formed by providing an annular groove from the lower end side of the tubular body 41, and is formed thinner than the wall thickness of the lid 42. The lid body 42 has a bulging portion 47 that bulges downward from the inside of the flange portion 45 in a substantially hemispherical shape. Inside the bulging portion 47, the lower end 61a of the suction portion 61 of the liquid absorbing member 6, which will be described later, is inserted and arranged.

In the present embodiment, an annular groove is provided from the lower end side of the tubular body 41 between the flange portion 45 of the lid 42 and the thick portion 44 of the tubular body 41 to form the thin portion 46. An annular groove may be provided in the flange portion 45 of the lid 42 from the inside of the body 41 to form the thin portion 46. Further, the groove does not necessarily have to be annular, may be discontinuous, and its depth does not have to be uniform. In any case, it suffices that the flange portion 45 of the lid 42 and the lower end 41a of the tubular body 41 are sealed in an unused state, and the flange portion 45 is pushed by the lower end 81a of the pushing member 8 as described later. The thin portion 46 having a structure that allows the lid body 42 to be broken and opened when pressed may be used.

The folded-back portion 43 has a substantially cylindrical outer shape that is one size larger than the tubular body 41, and is formed by folding the upper end 41b of the tubular body 41 outward by 180 ° to form a continuous substantially U-shaped cross section. An annular groove-shaped fitting recess 48 for fitting the ridge 25 provided on the neck 22 of the container 2 described above is formed on the inner surface 43a in which the folded-back portion 43 faces the outer surface of the tubular body 41. When the ridge 25 is replaced with a screw thread, a screw groove may be provided instead of the fitting recess 48. The inner diameter of the folded-back portion 43 is substantially the same as or slightly larger than the outer diameter of the neck portion 22 of the container 2. The ridge 25 of the neck portion 22 and the fitting recess 48 of the folded portion 43 may be provided in reverse. The outer surface 43b of the folded-back portion 43 is inclined in a direction that slightly expands outward toward the lower side.

The gap 49 between the tubular body 41 and the folded-back portion 43 above the fitting recess 48 has substantially the same width as the wall thickness of the neck portion 22 of the container 2. Further, the depth of the gap 49 is set to a depth at which the upper end 22a of the neck portion 22 abuts on the inner surface of the folded-back portion 43 with the protrusion 25 fitted in the fitting recess 48. Therefore, the tubular body 41 of the inner plug 4 is inserted through the opening 24 of the container 2, the lid 42 is arranged in the container 2, and the protrusion 25 of the neck portion 22 is fitted into the fitting recess 48 of the folded-back portion 43. Then, the upper end 22a of the neck portion 22 fits into the gap 49 between the tubular body 41 and the folded-back portion 43, the opening 24 is closed, and the container is sealed.

As shown in FIG. 5, the liquid absorbing member 6 has a substantially prismatic suction portion 61 immersed in the chemical solution in the container 2, and a substantially rectangular plate-shaped volatilization portion integrally continuous with the upper end 61b of the suction portion 61. It has 62. The liquid absorbing member 6 is formed by, for example, shaping a non-woven fabric having a uniform thickness. The lower end 61a of the suction portion 61 is chamfered according to the inner surface shape (hemispherical shape) of the lid 42 of the inner plug 4. The shape of the liquid absorbing member 6 can be arbitrarily changed, and any shape may be used as long as it can be held by the pushing member 8 described later. For example, the suction portion 61 and the volatilization portion 62 can be separated from each other, and the thicknesses of the suction portion 61 and the volatilization portion 62 can be made different, and the structure may be such that they are at least in contact with each other when arranged in a used state.

As shown in FIG. 6, the pushing member 8 includes a substantially cylindrical pushing cylinder 81 for inserting and arranging the suction portion 61 of the liquid absorbing member 6, an accommodating portion 82 for accommodating and arranging the volatilizing portion 62 of the liquid absorbing member 6, and a shaft. It integrally has a substantially disk-shaped pressing portion 83 provided at the upper end in the direction. That is, the pushing member 8 holds the liquid absorbing member 6 by inserting and arranging the suction portion 61 of the liquid absorbing member 6 in the pushing cylinder 81 and accommodating and arranging the volatilizing portion 62 of the liquid absorbing member 6 in the accommodating portion 82. Has a structure that can be

Then, the pushing member 8 inserts the pushing cylinder 81 into the tubular body 41 of the inner plug 4 while holding the liquid absorbing member 6, and inserts the pressing portion 83 into the upper end opening 92 of the cover 9 (see FIG. 1). ) To be attached. That is, the outer diameter of the push-in cylinder 81 is designed to be slightly smaller than the inner diameter of the tubular body 41 of the inner plug 4, and the outer diameter of the pressing portion 83 has a shape that allows it to be inserted into the upper end opening 92 of the cover 9. Has been done. The mounting structure and mounting method of the push-in member 8 will be described later.

The lower end 81a of the push-in cylinder 81 separated from the accommodating portion 82 is provided with a rupture claw 84 having a pointed downward shape. From a different point of view, the tip of the breaking claw 84 functions as the lower end 81a of the push-in cylinder 81. That is, when the push-in cylinder 81 is pushed into the tubular body 41 of the inner plug 4, the flange portion 45 of the lid body 42 is partially pressed by the tip of the breaking claw 84, and the lid body 42 is along the thin portion 46. Is being pushed open. In the present embodiment, the sealing claw 84 has a shape in which the tip of the push-in cylinder 81 is diagonally cut halfway. By not providing the breaking claw 84 continuously on the entire circumference of the push-in cylinder 81, the lid body 42 is not completely separated, and a part of the lid body 42 is connected to the lower end 41a of the tubular body 41. Can be.

At the lower end of the push-in cylinder 81 and on the opposite side of the breaking claw 84 in the circumferential direction, the push-in cylinder 81 is pushed into the tubular body 41 of the inner plug 4 to open the lid 42, and then the tubular body 41 is formed. A lid locking portion 85 for locking the lid 42 in a partially connected state in the open state shown in FIG. 9 is provided. The protruding length of the lid locking portion 85 is shorter than the protruding length of the breaking claw 84. Therefore, when the push-in cylinder 81 is pushed into the tubular body 41, the tip of the breaking claw 84 first abuts on the flange portion 45 of the lid body 42, and the lid body 42 partially from the lower end 41a of the tubular body 41. The lid body 42 is locked in the open state by the lid locking portion 85 on the opposite side of the separation starting portion in the circumferential direction. Two notches 86 are provided between the breaking claw 84 and the lid locking portion 85.

The accommodating portion 82 has a rectangular recess 71 that matches the shape of the volatilizing portion 62 of the liquid absorbing member 6. The recess 71 is partitioned by a bottom wall portion 72, a back support portion 73, a pair of side wall portions 74, 74, and a pressing portion 83. That is, the front surface of the recess 71 is open, and the liquid absorbing member 6 can be attached from the front surface side. The bottom wall portion 72 is formed with a circular opening 72a communicating with the upper end opening of the push-in cylinder 81.

The back support portion 73 includes a semi-cylindrical portion 76 provided between the side wall portions 74 and 74 on both sides via slits 75 and 75. The slits 75 and 75 function as volatilization holes. In the center of the semi-cylindrical portion 76, a volatilization hole 76a extending vertically is provided. The recess 71 is provided with an inclined guide surface 71a that connects the lower portion of the semi-cylindrical portion 76 and the edge of the opening 72a. Two ribs 77, 77 extending vertically are integrally projected on both sides of the volatilization hole 76a of the semi-cylindrical portion 76. The pair of side wall portions 74, 74 have a shape bent into an L-shaped cross section, and the bent portion 74a (only one of them is shown in FIG. 6) functions as a part of the back support portion 73.

When the liquid absorbing member 6 is attached to the pushing member 8, first, the lower end 61a of the sucking portion 61 of the liquid absorbing member 6 is inserted into the opening 72a of the pushing member 8 from the front surface side of the recess 71. At this time, the lower end 61a is guided to the opening 72a by the guide surface 71a, and the suction portion 61 is easily inserted and arranged in the push-in cylinder 81. Then, after the suction portion 61 is inserted and arranged in the push-in cylinder 81, the volatilization portion 62 of the liquid absorbing member 6 is accommodated and arranged in the recess 71 of the accommodating portion 82. In this state, the front side of the volatilization portion 62 is opened, and the back surface of the volatilization portion 62 is supported by the back surface support portion 73. That is, the back surface of the volatilization portion 62b is supported by the edges 76b and 76b of the semi-cylindrical portion 76 and the bent portions 74a and 74a of the side wall portions 74 and 74. The ends 77a, 77a of the ribs 77, 77 are located away from the recesses 71 than the edges 76b, 76b of the semi-cylindrical portion 76, and are between the edges 76b, 76b of the semi-cylindrical portion 76 and the ribs 77, 77. The space is not blocked by the volatilization portion 62.

Further, in this state, the lower end 61a of the suction portion 61 of the liquid absorbing member 6 projects downward from the lower end 81a of the push-in cylinder 81, that is, the tip of the breaking claw 84. In this way, the lower end 61a of the suction portion 61 protruding from the tip of the sealing claw 84 inserts the push-in cylinder 81 of the push-in member 8 in the state of holding the liquid-absorbing member 6 into the tubular body 41 of the inner plug 4. It is arranged inside the lid 42 in the state shown in FIG. 7 (the state in which the lid 42 is not broken). In other words, the lid body 42 is formed in a hemispherical shape protruding downward in order to accommodate the lower end 61a of the suction portion 61 of the liquid absorbing member 6 protruding from the lower end 41a of the tubular body 41.

On the outside of the side wall portions 74 and 74 of the accommodating portion 82, slide protrusions 87 and 87 for vertically and vertically slidably attaching the pushing member 8 to the cover 9 are provided so as to project. The slide protrusion 87 is formed in a T-shaped cross section and is engaged with a pair of slide rails 94, 94 (see FIGS. 7 and 8) provided inside the cover 9. The lower end of the slide rail 94 is open for inserting the slide protrusion 87. In the state where the pushing member 8 is arranged in the unused state shown in FIG. 7, the upper end portion 87a of the slide protrusion 87 abuts on the end portion of the slide rail so that the pushing member 8 does not move further upward.

Further, on the outside of the side wall portions 74 and 74 of the accommodating portion 82, the engaging members 8 are engaged with the engaging claws 95 and 95 of the cover 9 in the unused state shown in FIG. 7, respectively. The protrusions 88 and 88 are projected. The engaging protrusions 88 and 88 are provided above the slide protrusion 87 so as to be separated from each other. With the engaging protrusions 88 and 88 of the pushing member 8 engaged with the engaging claws 95 and 95 of the cover 9, the pushing member 8 is locked in the unused state shown in FIG. In this state, the pushing member 8 is separated above the inner plug 4.

Further, a pair of holding claws 89, 89 separated in the radial direction are projected downward on the lower surface side of the bottom wall portion 72 of the accommodating portion 82. When the pushing member 8 is pushed into the used state shown in FIGS. 8 and 9, the holding claws 89 and 89 engage with the lower end edge of the folded-back portion 43 of the inner plug 4 and lock the pushing member 8 at this position. Works like That is, when the pressing portion 83 of the pushing member 8 is pushed in and the pushing member 8 is arranged in the used state, the pushing member 8 is held at this position and cannot return to the unused state.

As described above, the outer surface 43b of the folded-back portion 43 of the inner plug 4 is inclined in the direction of expanding outward toward the lower side. Therefore, when the pushing member 8 is pushed in, the holding claw 89 is pushed by the outer surface 43b and elastically deformed so as to be curved outward. Then, after the holding claw 89 exceeds the outer surface 43b, the holding claw 89 is restored to its original shape and engages with the lower end edge of the folded-back portion 43. Therefore, when the pushing member 8 is pushed into the used state, it cannot be returned to the unused state unless the user spreads the pair of holding claws 89 and 89 outward to disengage the engagement. The fact that the user has pushed the pushing member 8 and placed it in the used state can be recognized by the engagement sound when these holding claws 89 engage with the lower end edge of the folded-back portion 43, and the pushing member 8 is used. You can check the operation of pushing it into the state.

The pressing portion 83 is formed in a shape in which the upper surface pressed by the user is curved and the center is recessed downward. A part of the pressing portion 83 protrudes from the upper end opening 92 of the cover 9 in the unused state shown in FIG. Since the pressing portion 83 protrudes from the upper end opening 92, the user can easily recognize the pressing portion 83 and push the pressing portion 83 deeply. As shown in FIG. 1, a slight gap 96 is provided between the pressing portion 83 and the upper end opening 92 of the cover 9. In other words, the outer peripheral edge of the pressing portion 83 is partially recessed, and a gap 96 is formed between the pressing portion 83 and the upper end opening 92. The gap 96 functions as a volatilization hole for volatilizing the chemical solution.

Hereinafter, the procedure for assembling the above-mentioned volatilizer 10 will be described.
First, the tubular body 41 of the inner plug 4 is inserted through the opening 24 of the container 2 containing the chemical solution, and the lower end 41a of the tubular body 41 is immersed in the chemical solution. Then, the ridge 25 of the neck portion 22 of the container 2 is fitted into the fitting recess 48 of the folded-back portion 43 of the inner plug 4, and the inner plug 4 is fixed to the neck portion 22 of the container 2. In this state, the container 2 is sealed by the inner plug 4. Further, in this state (state of FIG. 7), between the top of the inner plug 4 on the bulging side and the bottom of the container 2, when the lid 42 is opened, the bottom of the container 2 is placed. There is a gap (see FIG. 9) that does not come into contact with each other. This gap does not necessarily have to be large enough to allow the lid 42 to be fully opened, and at least the lower end of the suction portion 61 of the liquid absorbing member 6 is provided in the used state (the states shown in FIGS. 8 and 9) in which the lid 42 is opened. It suffices if 61a can come into contact with the bottom of the container 2.

Second, the liquid absorbing member 6 is attached to the pushing member 8. At this time, first, the lower end 61a of the suction portion 61 of the liquid absorbing member 6 is inserted into the opening 72a at the bottom of the recess 71 from the front of the pushing member 8, and the suction portion 61 is inserted into the pushing cylinder 81 of the pushing member 8. Push into. At this time, the lower end 61a of the suction portion 61 is pressed against the guide surface 71a on the back side of the recess 71, and the lower end 61a is guided toward the opening 72a along the guide surface 71a. Then, after the suction portion 61 is inserted into the push-in cylinder 81, the volatilization portion 62 is housed and arranged in the recess 71.

Thirdly, the pushing member 8 holding the liquid absorbing member 6 as described above is attached to the inside of the cover 9. At this time, the pushing member 8 is inserted from the lower end edge 91 side of the cover 9 with the pressing portion 83 at the head, and the pair of slide protrusions 87 of the pushing member 8 are inserted into the pair of slide rails 94 inside the cover 9. At the same time, the pressing portion 83 of the pushing member 8 is inserted into the upper end opening 92 of the cover 9. Then, the pushing member 8 is pushed inside the cover 9 until the pair of engaging claws 95, 95 of the cover 9 are engaged with the pair of engaging protrusions 88, 88 of the pushing member 8. In this state, the pushing member 8 is engaged with the cover 9, and there is no concern that the push member 8 will fall off from the lower end side of the cover 9.

The first procedure described above is performed separately from the second and third procedures described above, and is performed in parallel with the second and third steps, or after the second and third steps. May be good.

Finally, the push-in cylinder 81 of the push-in member 8 integrated with the cover 9 is inserted into the tubular body 41 of the inner plug 4 fixed to the container 2, and the lower end edge 91 of the cover 9 is inserted into the step portion 26 of the container 2. Fit into. This completes the assembly of the volatilizer 10. In this state, the lower end 61a of the suction portion 61 of the liquid absorbing member 6 protruding from the lower end 81a of the pushing cylinder 81 of the pushing member 8 comes into contact with the inner surface of the lid 42 of the inner plug 4, and the pushing cylinder 81 The lower end 81a, that is, the tip of the breaking claw 84 is slightly separated upward from the flange portion 45 of the lid 42.

When the volatilizer 10 assembled as described above is changed from the unused state to the used state, the user can use the pushing member 8 which is inside the upper end opening 92 of the cover 9 and a part of which protrudes from the upper end opening 92. The pressing portion 83 of the above is pressed downward and pushed into the upper end opening 92. As a result, the pushing member 8 is moved from the state shown in FIG. 7 to the state shown in FIG. 8, and as shown in FIG. 9, the lid 42 of the inner plug 4 is ruptured, and the use of the volatilizer 10 is started. To.

At this time, first, the pair of engaging protrusions 88 of the pushing member 8 are disengaged from the corresponding engaging claws 95 of the cover 9, and the pair of holding claws 89 of the pushing member 8 come into contact with the folded-back portion 43 of the inner plug 4 and are pushed. The tip of the opening claw 84 of the member 8 comes into contact with the flange portion 45 of the lid 42 of the inner plug 4. The timing at which the holding claw 89 contacts the folded-back portion 43 and the timing at which the breaking claw 84 contacts the flange portion 45 are substantially the same, but the length of the holding claw 89 and the like are adjusted so as to slightly shift the contact timing. You may. When the tip of the breaking claw 84 moves toward the flange portion 45 of the inner plug 4, the tip of the breaking claw 84 moves downward while contacting the inner surface of the thick portion 44 of the tubular body 41, and the flange portion. The tip of the breaking claw 84 is guided toward 45.

When the pressing portion 83 of the pushing member 8 is further pushed in from this state, the pair of holding claws 89 elastically deforms while sliding in contact with the outer surface 43b of the folded portion 43 and spreads outward, and after overcoming the folded portion 43, the original shape. It returns to and engages with the lower end edge of the folded-back portion 43. At the same time, the tip of the breaking claw 84 pushes the flange portion 45, and the lid 42 starts to open from the portion where the breaking claw 84 is pressed. At this time, as described above, the suction portion 61 of the liquid absorbing member 6 in contact with the inner surface of the lid 42 pushes the lid 42 from the inside and assists the force to open the lid 42.

When the pushing member 8 is pushed to the lowermost end in the movable range and the pair of holding claws 89 engages with the lower end edge of the folded-back portion 43, the lid body 42 rotates substantially 90 ° downward as shown in FIG. The lower end 61a of the suction portion 61, which is opened in this state and protrudes downward from the breaking claw 84, comes into contact with the bottom of the container 2. Since the liquid absorbing member 6 is made of a non-woven fabric or the like, it expands when it absorbs the chemical solution, and the length of the sucking portion 61 becomes slightly longer. Therefore, the length of the suction portion 61 is set to such a length that the lower end 61a of the suction portion 61 that has absorbed the chemical solution comes into contact with the bottom of the container 2 when arranged in the usage state shown in FIGS. 8 and 9. do it.

According to the present embodiment, since the lid 42 provided at the lower end of the inner plug 4 is made substantially hemispherical and bulges downward from the lower end of the tubular body 41, the tip 81a of the breaking claw 84 of the pushing member 8 is a lid. The lower end 61a of the suction portion 61 of the liquid absorbing member 6 can be arranged below the position where the flange portion 45 of the body 42 is pressed, and the lower end of the suction portion 61 from the breaking claw 84 with the lid 42 open. 61a can be popped out. Therefore, the lower end 61a of the liquid absorbing member 6 can be brought into contact with the bottom of the container 2 while allowing the opening by piercing.

In the present embodiment, the lid 42 is prevented from being sandwiched between the lower end 61a of the suction member 61 protruding from the lower end 41a of the tubular body 41 and the bottom of the container 2. Was not separated from the tubular body 41, and the open lid 42 was locked in the open state shown in FIG. That is, immediately before the pushing member 8 is pushed to the lowermost end, the lid locking portion 85 at the lower end of the pushing member 8 is projected downward from the lower end 41a of the tubular body 41 so as to support the edge of the lid body 42. did. As a result, it is possible to prevent the lid 42 from being pinched between the lower end 61a of the suction portion 61 of the liquid absorbing member 6 and the bottom of the container 2, and the chemical solution remaining on the bottom of the container 2 is sucked up and volatilized. be able to.

Further, as in the present embodiment, by making the lid body 42 substantially hemispherical, when the lid body 42 is rotated downward with a part connected to the lower end of the tubular body 41, the lid body 42 The arcuate locus drawn by the tip of the rotation can be reduced, and the distance between the lid 42 and the bottom of the container 2 can be minimized. On the other hand, for example, when the lid body 42 is made into a cylindrical shape, the locus drawn by the tip of rotation becomes larger in a cylinder having the same radius than in the hemispherical lid body 42. For example, by making the lid 42 substantially hemispherical as in the present embodiment, the tubular body 41 of the inner plug 4 can be made slightly longer, and the degree of freedom in design can be increased.

Further, when the pushing cylinder 81 of the pushing member 8 is inserted into the tubular body 41 of the inner plug 4 and pushed, the outer peripheral surface of the pushing cylinder 81 is slid in a state of being slidably contacted with the inner surface of the thick portion 44. As shown in FIGS. 8 and 9, the outer peripheral surface of the push cylinder 81 and the inner peripheral surface of the tubular body 41 (inner surface of the thick portion 44) are brought into close contact with each other in a state where the push member 8 is pushed into the used state. Be sealed. As a result, it is possible to prevent the chemical solution from entering the gap between the outer peripheral surface of the push-in cylinder 81 and the inner surface of the tubular body 41, and it is possible to prevent a problem that the chemical solution leaks through the gap.

As described above, according to the first embodiment, the lid body 42 is gradually separated from the lower end 41a of the tubular body 41 by pushing the flange portion 45 of the lid body 42 with the tubular breaking claw 84, and the lid body 42 is pushed in. Since the lower end 61a of the suction portion 61 of the liquid absorbing member 6 inserted into the cylinder 81 is projected from the breaking claw 84, the lower end 61a of the suction portion 61 is brought into contact with the bottom of the container 2 with the lid 42 open. The chemical solution remaining on the bottom of the container 2 can be sucked up and volatilized, and waste of the chemical solution can be eliminated.

Further, according to the present embodiment, when the volatilizer 10 is started to be used, the cover 9 is opened once, the container 2 is ruptured, the liquid absorbing member 6 is immersed in the chemical solution, and then the cover is started. The troublesome work of returning the 9 to the original position is not required, and the use can be started by simply pushing the pressing portion 83 of the pressing member 8 until it clicks, improving convenience. Can be done.

Next, the volatilizer 110 according to the second embodiment will be described with reference to FIGS. 10 and 11. FIG. 10 is a vertical cross-sectional view of the volatilizer 110 in an unused state, and FIG. 11 is a vertical cross-sectional view of the volatilizer 110 in a used state. Here, the components having the same functions as the volatilizer 10 of the first embodiment described above are designated by the same reference numerals and detailed description thereof will be omitted, and only the configuration different from that of the volatilizer 10 of the first embodiment will be omitted. explain. Since the procedure for assembling the volatilizer 110 is the same as that of the volatilizer 10 of the first embodiment, the description thereof will be omitted.

In the volatilization device 110 of the present embodiment, the pressing portion 83'of the pushing member 8 is formed of a relatively thin flat plate-like body, and the concave portion 71 accommodating the volatilizing portion 62'of the liquid absorbing member 6 is covered by that amount. It was placed near the upper end of 9. As a result, the ratio of the length of the suction portion 61'to the total length of the volatilizer 110 is increased, and the axial height (that is, capacity) of the container 2'is increased. Further, in the present embodiment, the liquid absorbing member 6 is held so as to be slidable up and down with respect to the pushing member 8.

That is, the vertical size of the volatilization portion 62'is smaller than the vertical size of the recess 71. In other words, in the unused state shown in FIG. 10, a space is formed between the volatilization portion 62'and the bottom wall portion 72 of the recess 71. Therefore, when the pushing member 8 is pushed from the unused state of FIG. 10 to the used state of FIG. 11, that is, when the lid 42'is opened, the liquid absorbing member 6 falls due to its own weight, and the lower end of the sucking portion 61'. 61a comes into contact with the bottom of the container 2. In other words, in the unused state of FIG. 10, the lower end 61a of the suction portion 61'of the liquid absorbing member 6 is supported by being in contact with the inner surface of the lid 42'that seals the lower end of the tubular body 41. ..

Further, in the present embodiment, when the pushing member 8 is pushed in, the holding claw 89 is engaged with the annular rib 27 provided on the outer periphery of the neck portion 22 of the container 2. As a result, the pushing member 8 can be directly engaged with the container 2 instead of engaging with the inner plug 4 as in the first embodiment, and the pushing member 8 can be engaged regardless of the state of the inner plug 4. Can be reliably retained in use.

As described above, according to the second embodiment, when the pushing member 8 is pushed in to open the lid 42', the liquid absorbing member 6 is dropped by its own weight and the lower end 61a of the sucking portion 61'is the bottom of the container 2. The volatilization portion 62 of the liquid absorbing member 6 can be made smaller, and the liquid absorbing member 6 can be easily attached to the pushing member 8 when assembling the volatilizing device 10, and the volatilizing device 110 can be manufactured. The cost can be reduced. Further, after adopting such a simple configuration, the lower end 61a of the suction portion 61'of the liquid absorbing member 6 can always be brought into contact with the bottom of the container 2 at the same pressure, and the reliability can be improved. .. Needless to say, the same effect as that of the first embodiment described above can be obtained in this embodiment as well.

FIG. 12 is a vertical cross-sectional view showing a volatilizer 200 which is a modification of the volatilizer 10 of the first embodiment described above. Here, too, components that function in the same manner as in the first embodiment described above are designated by the same reference numerals, detailed description thereof will be omitted, and only components different from those in the first embodiment will be described.

According to the volatilizer 200, the pushing member 8'that holds the liquid absorbing member 6 immovably does not have the slide protrusion 87 or the engaging protrusion 88, but instead has a pair of engaging claws 201, 201. There is. The engaging claws 201 and 201 are projected so as to be curved upward from the outside of the side wall portions 74 and 74 of the accommodating portion 82, respectively, and are separated and opposed to the opposite sides in the radial direction of the pushing member 8'. It is provided.

On the other hand, the cover 9 is provided with a pair of engaging protrusions 202, 202 on the edge of the upper end opening 92. The engaging protrusions 202 and 202 are provided corresponding to the engaging claws 201 and 201 of the pushing member 8', and are engaged when the pushing member 8'is inserted through the upper end opening 92 of the cover 9 and mounted. The claws 201 and 201 are engaged with each other.

Therefore, according to this modification, the pushing member 8'can be inserted and attached through the upper end opening 92 of the cover 9, and the volatilizer 200 can be easily assembled. The structure of this modification can also be applied to the volatilizer 110 of the second embodiment.
