JP 2012-077684 A

  Since the volatilization tool described in Patent Document 1 is supported from below by the upper surface of the raised part in a state before use such as during distribution, the raised part of the lower surface of the volatilized member. The upward pressure from the raised portion acts on the portion that comes into contact with the upper surface of the volatile member, that is, the portion that comes into contact with the upper end of the liquid absorbent core when the volatile tool is used due to the weight of the volatile member. Therefore, this part may become the shape which became depressed upward from the other area | region in the lower surface of the said volatilization member. In this case, since the relative position with respect to the upper end of the portion facing the upper end of the liquid-absorbing core of the lower surface of the volatilization member is displaced upward, when using the volatilization tool, that is, in a state where the cap is removed. A good contact state between the volatilization member and the liquid absorbent core cannot be obtained, and the volatilization efficiency of the volatilization liquid is significantly reduced.

  An object of the present invention is to provide a volatilization tool capable of ensuring a stable contact state between the upper end of the liquid absorbent core and the lower surface of the volatilization member.

  In order to solve the above-mentioned problem, the present invention is a volatilization tool for volatilizing a volatilizing liquid, which accommodates the volatilizing liquid and has an opening that opens upward, and is disposed in the accommodating member. And a liquid absorbing core that has a shape that is long in the vertical direction and absorbs the volatile liquid, a cap that is detachably attached to the opening so as to close the opening, and is attached to the housing member, A lid having a diffusion hole for diffusing the volatilization liquid, and when the cap is attached to the opening, the cap is held by the lid so that the cap is supported from below, and the cap Is removed, the lower surface comes into contact with the upper end of the liquid absorbent wick so that the volatile liquid can be evacuated from the liquid absorbent wick so that the volatile liquid can be volatilized. A volatilizing member that is held by the lid, and the housing member has a holding portion that holds the liquid absorbent core such that an upper end of the liquid absorbent core is positioned above the opening. The lid has a restraining portion that restrains displacement of the volatilization member in a direction perpendicular to the longitudinal direction of the liquid-absorbing core, and the cap is pressed against the upper end of the housing member to thereby accommodate the housing member. A seal part that prevents leakage of the volatile liquid to the outside, a bulge part that protrudes upward from the seal part so as to avoid contact with the upper end of the liquid absorbent core, and an outer side of the bulge part. A volatilization tool is provided having a support portion that protrudes upward from the upper end of the raised portion and supports the volatilization member from below.

  According to the present invention, the support portion protrudes above the bulge portion outside the bulge portion and supports the volatile member from below, that is, the lower surface of the volatile member does not contact the bulge portion. Thus, since this volatilization member is supported from below, the portion of the lower surface of the volatilization member that comes into contact with the support portion may be recessed upward, but the upper end of the liquid absorbing core among the lower surface of the volatilization member Alternatively, the portion facing the raised portion (the portion in contact with the upper end of the liquid-absorbing core when the cap is removed) does not have an upwardly recessed shape as in the prior art, and the restraint portion Since the volatilization member is positioned with respect to the liquid absorption core, in a state where the cap is removed, a portion of the lower surface of the volatilization member facing the upper end of the liquid absorption core (on the support portion) Site inside than lifting been site) is reliably in contact with the upper end of the wick. Therefore, the stable contact state of the upper end of the said liquid absorption core at the time of use and the lower surface of the said volatilization member is ensured.

  In this case, the cap has a fixed portion that is fixed to the outer peripheral surface of the opening, and the support portion has an outer peripheral surface that is formed by extending the outer peripheral surface of the fixed portion upward. Is preferred.

  In this way, the detachability of the cap is improved. Specifically, normally, when the cap is removed, the fixed portion of the cap is gripped by a finger or the like, but the support portion has an outer peripheral surface that is formed by extending the outer peripheral surface of the fixed portion upward. Therefore, the area that can be gripped when removing the cap is increased, thereby improving the detachability of the cap.

  Moreover, in this invention, it is preferable that the said support part has a shape continuously extended over the whole region of the circumferential direction centering on the said protruding part.

  In this way, since the pressure acting on the volatilization member from the support part is reduced, the amount of deformation of the part of the lower surface of the volatilization member that contacts the upper end of the support part is suppressed, and the lower surface It is suppressed that the hollow of the shape corresponding to the upper end of a support part is formed. Therefore, even when the dent is formed, deformation that may occur in a portion of the lower surface of the volatilization member that faces the upper end of the liquid absorbent core is suppressed, and thus the liquid absorbent core in use is suppressed. The contact state between the upper end of the substrate and the lower surface of the volatile member is further stabilized.

  As mentioned above, according to this invention, the volatile tool which can ensure the stable contact state of the upper end of a liquid absorption core and the lower surface of a volatile member can be provided.

The contact portion 34 has a shape that projects from the upper end of the fitting tube portion 32 toward the outside in the radial direction. In addition, the outer peripheral surface of the fitting cylinder part 32 and the inner peripheral surface of the opening part 12 are closely_contact | adhered so that the volatilization liquid in the container 11 may not leak out of the said container 11 from both.

  The liquid absorption core 40 has a shape that is long in the vertical direction, and is disposed in the container 11. The liquid absorbent core 40 is made of, for example, filter paper. In the present embodiment, the upper end 40 a of the liquid absorbent core 40 is formed on a flat surface parallel to a direction orthogonal to the longitudinal direction of the liquid absorbent core 40.

  The cap 50 is attached to the opening 12 so as to be detachable from the opening 12. The cap 50 has a shape that closes the opening 12. As shown in FIGS. 2, 3 (a), and 3 (b), the cap 50 is pressed against the fixed portion 51 fixed to the outer peripheral surface of the opening 12 and the upper end of the housing member 10. The seal portion 52 that prevents the volatilization liquid from leaking out of the housing member 10, the raised portion 53 that is shaped to rise upward from the seal portion 52, and the support portion 54 that supports the volatilization member 70 from below. In the present embodiment, the cap 50 is formed of a synthetic resin.

  The fixed part 51 is cylindrical. The fixed portion 51 is formed to be screwable with the opening 12.

  The seal portion 52 includes a sandwiching surface 52 a that sandwiches the contact portion 34 with the upper end of the opening 12, and a convex portion 52 b that protrudes from the sandwiching surface 52 a toward the contact portion 34. The sandwiching surface 52 a is formed on a plane parallel to the contact portion 34. The convex part 52b has a shape connected over the whole area in the circumferential direction. When the clamping surface 52 a is pressed against the contact portion 34, the convex portion 52 b comes into pressure contact with the contact portion 34.

  The raised portion 53 is raised upward from the seal portion 52, more specifically from the clamping surface 52 a so as to avoid contact with the upper end 40 a of the liquid absorbent core 40.

  The support portion 54 is formed on the outer side of the raised portion 53 and has a shape that protrudes upward from the upper end of the raised portion 53 and supports the volatilization member 70 from below.

The support portion 54 has a shape that continuously extends over the entire area in the circumferential direction centering on the raised portion 53.

  The lid | cover 60 has the diffusion hole 60a (refer FIG. 1) for diffusing the volatilization liquid volatilized from the volatilization member 70. FIG. In addition, the lid 60 includes a holding piece 61 that holds the volatile member 70 and an urging portion 62 that urges the volatile member 70 downward. The holding piece 61 is connected to the restraining portion 61a that restrains the displacement of the volatilizing member 70 in the direction orthogonal to the longitudinal direction of the liquid absorbent core 40 (the left-right direction in FIG. 2), and is volatilized by being connected to the lower end of the restraining portion 61a. It has the receiving part 61b which receives the member 70 from the downward direction. As shown in FIG. 2, the urging unit 62 suppresses the vertical displacement of the volatilization member 70 with the support unit 54 in a state where the cap 50 is mounted (a state before use). In the state where 50 is removed (the state in use), the vertical displacement of the volatile member 70 is suppressed between the upper end 40a of the liquid absorbent core 40 or the receiving portion 61b. More specifically, the urging portion 62 bends upward both before and during use, and the volatilizing member 70 is moved downward by an elastic return force to return to the neutral position of the urging portion 62. The function of positioning the volatilization member 70 in the up-down direction is provided. In the present embodiment, the urging portion 62 has a leaf spring shape, and in addition to the two left and right positions sandwiching the axis of the liquid absorption core 40 shown in FIG. It is provided in a total of four places, two other places shifted in the vertical direction. However, the number and shape of the urging portions 62 are not limited to the above. The urging unit 62 may be any member that exhibits a function of positioning the volatile member 70 in the vertical direction before and during use of the volatile tool. In the present embodiment, the lid 60 is connected to the housing case 21 via a hinge portion 65 provided on one end side (the right side in FIG. 2) of the housing case 21.

  When the cap 50 is attached to the container 11, the volatilization member 70 is held by the lid 60 so as to be supported from below by the support portion 54 of the cap 50, and when the cap 50 is removed. (When using this volatilization tool), the lower surface 71 is held by the lid 60 so as to come into contact with the upper end 40a of the liquid absorbent core 40. Note that the volatilization member 70 sucks the volatilization liquid from the liquid absorption core 40 and volatilizes the volatilization liquid when the lower surface 71 comes into contact with the upper end 40 a of the liquid absorption core 40. The lower surface 71 of the volatilization member 70 is formed flat. In this embodiment, the volatilization member 70 is formed in a rectangular parallelepiped. This volatilization member 70 consists of a felt (nonwoven fabric) core, for example.

  Here, the use before and at the time of use of the volatilizer of this embodiment will be described.

  As shown in FIG. 2, the cap 50 is attached to the container 11 before use such as when the volatilizer is distributed, so that the volatilized liquid in the container 11 does not leak out of the container 11. In this state, the lower surface 71 of the volatilization member 70 is in contact with only the support part 54, and upward pressure from the support part 54 acts on the part in contact with the support part 54 due to the weight of the volatilization member 70. ing. Therefore, when this state is maintained for a long time, a portion of the lower surface 71 of the volatilization member 70 that is in contact with the support portion 54 has a shape that is recessed upward from the other region of the lower surface 71. There is. In this case, the shape of the recess is a shape corresponding to the support portion 54, that is, an annular shape.

  On the other hand, since the lower surface 71 of the volatilization member 70 is separated from the raised portion 53, upward pressure does not act on the portion of the lower surface 71 that faces the raised portion 53. Therefore, unlike the part which contacts the support part 54, the said part does not become a shape depressed upward by the upward pressure from the raised part 53.

  When this volatilization tool is used, the lid 60 is rotated around the hinge portion 65. At this time, since the volatilization member 70 is positioned by the holding piece 61 and the urging portion 62, it rotates together with the lid 60.

  Then, the cap 50 is removed, and the lid 60 is returned to the original posture. At this time, at least a portion of the lower surface 71 of the volatilization member 70 that faces the upper end 40a of the liquid absorbent core 40 is not recessed upward and is maintained in the original flat shape. The upper end 40a of the core 40 is in reliable contact. Thereby, the volatilization member 70 sucks up the volatilization liquid from the liquid absorption core 40.

  As described above, in the volatilization tool of the present embodiment, the support portion 54 protrudes upward from the raised portion 53 outside the raised portion 53 and supports the volatilized member 70 from below, that is, the volatilized member 70. Since the volatile member 70 is supported from below so that the lower surface 71 of the volatile member 70 does not come into contact with the raised portion 53, the portion of the lower surface 71 of the volatile member 70 that contacts the support portion 54 may be recessed upward. The portion of the lower surface 71 that faces the upper end 40a of the liquid absorbent core 40 or the raised portion 53 (the part that contacts the upper end 40a of the liquid absorbent core 40 when the cap 50 is removed) is recessed upward as in the prior art. Since it does not have a shape and the positioning of the volatile member 70 with respect to the liquid absorption core 40 is performed by the restraining portion 61a, the lower surface of the volatile member 70 is removed when the cap 50 is removed. Portion facing the upper end 40a of the wick 40 of the one (inner region than supported sites on the support portion 54) is reliably in contact with the upper end 40a of the wick 40. Therefore, a stable contact state between the upper end 40a of the liquid absorbent core 40 and the lower surface 71 of the volatile member 70 during use is ensured.

  Moreover, since the support part 54 has the outer peripheral surface of the shape which extended the outer peripheral surface of the to-be-fixed part 51 fixed to the outer peripheral surface of the opening part 12 upwards, the detachability of the cap 50 is improved. Specifically, normally, when the cap 50 is removed, the fixed part 51 of the cap 50 is gripped by a finger or the like, but the support part 54 has an outer periphery with a shape in which the outer peripheral surface of the fixed part 51 extends upward. Since the surface is provided, the area that can be gripped when the cap 50 is removed is increased, thereby improving the detachability of the cap 50.

  Moreover, since the support part 54 has the shape continuously extended over the whole circumferential direction centering on the protruding part 53, since the pressure which acts on the volatilization member 70 from the support part 54 is reduced, the volatilization member 70 of FIG. A deformation amount of a portion of the lower surface 71 that comes into contact with the upper end of the support portion 54 is suppressed, and formation of a recess having a shape corresponding to the upper end of the support portion 54 on the lower surface 71 is suppressed. Therefore, even if the dent is formed, deformation that may occur in the portion of the lower surface 71 of the volatilizing member 70 that faces the upper end 40a of the liquid absorbent core 40 is suppressed, and thus the liquid absorbent in use. The contact state between the upper end 40a of the core 40 and the lower surface 71 of the volatilization member 70 is further stabilized.

  Each embodiment disclosed this time should be considered as illustrative in all points and not restrictive.
