Description

Technical Field

[0001] The present invention relates to a chemical liquid diffuser for emitting volatile substances indoors or in a vehicle interior.

Background Art

[0002] Conventionally, as a chemical liquid diffuser installed indoors or in a vehicle interior, for example, the one described in Patent Document 1 has been proposed. The device described in Patent Document 1 includes a cylindrical exterior body, an interior body held inside the exterior body, and an absorber impregnated with a volatile substance such as a fragrance fixed to the interior body. Both openings of the exterior body are closed by respective closing plates, and the closing plates are provided with pull-top type lids that can be detached leaving the outer edge portion.

[0003] When using the chemical liquid diffuser, first, pull up the pull tab of one of the closing plates of the exterior body and pull to detach the lid from the closing plate to form a volatilization opening. Place the chemical liquid diffuser at a predetermined location with the volatilization opening facing upward. When the volatilization of the fragrance decreases after using it for a certain period in this state, turn the exterior body upside down and detach the lid provided on the other closing plate of the exterior body to form a volatilization opening. By turning the exterior body upside down, the fragrance impregnated below the absorber volatilizes from the newly formed volatilization opening and volatilizes without leaving any fragrance.

Embodiments for Carrying out the Invention

[0017] (Overall Configuration of Chemical Liquid Volatilizer 10) Embodiments of the present invention will be described with reference to the drawings. FIGS. 1 to 8 show a chemical liquid volatilizer 10 according to an embodiment of the present invention. The chemical liquid volatilizer 10 is for volatilizing and emitting a liquid that is a volatile substance, and includes a bottomed container 11 for storing the chemical liquid, a holder 所20 that is housed in the container 11 and holds a first impregnated body 30 impregnated with the chemical liquid, a seal portion 40 that closes the opening 14 of the container 11, a chemical liquid sealed in the container 11, and a cap 50 that is placed on the upper part of the container 11 and has a ventilation hole. In this specification, the vertical direction in FIG. 2 is defined as the vertical direction of the chemical liquid volatilizer 10, the direction from the opening 14 of the container 11 toward the bottom wall 12 is defined as the downward direction, and the direction opposite to the downward direction is defined as the upward direction. However, the vertical direction does not necessarily follow the vertical direction, and the container 11 is not necessarily placed on a horizontal plane for use. Also, the center point of the annular holder member 21 (FIG. 4) is referred to as the center point P of the chemical liquid volatilizer 10 or the center point P of the holder 20, the inner side refers to the direction toward the axial direction of the holder passing through the center point P or the center point P, and the outer side refers to the opposite side of the inner side.

[0018] (Container 11) As shown in Figures 2, 7, and 8, the container 11 has a circular bottom wall 12 when viewed from above, and a peripheral wall 13 that extends upward from the outer edge of the bottom wall 12, with an opening 14 formed at the top. The material constituting the container 11 is not particularly limited to metals such as aluminum or steel, or synthetic resins such as polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), polystyrene (PS), or acrylonitrile-butadiene-styrene resin (ABS). Any material that can contain the liquid together with the seal portion 40 in a liquid-tight and airtight manner is acceptable. At the bottom of the inside of the container 11, a plurality of ribs 15 are provided at predetermined intervals in the circumferential direction, connecting the bottom wall 12 and the peripheral wall 13. The ribs 15 are plate-shaped members that extend in the radial direction of the container 11. The base portion 22 of the holder 20, which will be described later, abuts against the upper surface of the ribs 15. Positioning the holder 20 above the ribs 15 prevents the holder 20 from rattling. An engaging projection 16 for engaging with the cap 50 is formed around the outer circumference of the upper end of the peripheral wall 13.

[0019] The liquid is a volatile liquid that turns into a gas at room temperature of at least 1 to 30 degrees Celsius. The liquid may contain, for example, fragrances, deodorizers, fungicides, antibacterial agents, insecticides, repellents, etc., and is not limited to, but is one example of a liquid containing a glycol ether solvent and a fragrance.

[0020] (Holder 20) The container 11 houses the holder 20. As shown in Figure 6, the holder 20 has a shape that allows it to be removed from the container 11, inverted, and re-stored in the container 11, and is composed of a pair of first and second holder members 21A and 21B of the same shape. The first impregnated body 30 and the second impregnated body 35 are housed inside the holder 20.

[0021] In the following description, when it is not necessary to distinguish between the first holder member 21A and the second holder member 21B, they will simply be referred to as "holder member 21". When it is necessary to distinguish between the first and second holder members 21A and 21B and their configurations, the first holder member 21A and the components of the first holder member 21A may be denoted with "A", and the second holder member 21B and the components of the second holder member 21B may be denoted with "B". In addition, in the following description of the configuration of the holder members, the vertical direction of the holder member 21 in the side view of Figure 5 is referred to as the vertical direction of the holder member 21.

[0022] As shown in Figures 3 to 5, each holder member 21 has an annular shape and comprises a base portion 22, an outer peripheral portion 25 erected from the outer peripheral edge of the upper surface of the base portion 22, a support portion 28 that supports the side surface of the first impregnated body 30, and a flange portion 29 that abuts against the second impregnated body 35. The holder member 21 is made of a material including, for example, metals such as aluminum or steel, or synthetic resins such as polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), polystyrene (PS), and acrylonitrile-butadiene-styrene resin (ABS), and is formed, for example, by injection molding, but the material and molding method are not limited thereto.

[0023] The base portion 22 has an L-shaped cross-section and includes an annular first piece portion 23 extending along a plane perpendicular to the vertical direction, and an annular second piece portion 24 extending downward and outward from the inner edge of the first piece portion 23.

[0024] A flange portion 29 is provided along the lower end edge of the second piece portion 24 of the base portion 22, projecting radially inward. The flange portion 29 is strip-shaped along a plane perpendicular to the vertical direction, and in this embodiment, four are provided at equal intervals. In this embodiment, the circumferential length of each flange portion 29 along the second piece portion 24 is set to approximately 1 / 5 of the circumference of the second piece portion 24, and the width (radial length) of the flange portion 29 is set to approximately 1 / 4 of the inner diameter of the lower end of the second piece portion 24 of the base portion 22, but this is not limited to this. The number of flange portions 29 is also not limited, and they may be provided around the inside of the second piece portion 24 of the base portion 22, and there may be two, three, or five or more.

[0025] On the upper surface of the first piece 23 of the base 22, four outer peripheral portions 25 are provided radially outward and circumferentially in an upward direction. In this embodiment, each outer peripheral portion 25 is provided at a position corresponding to each flange portion 29 and is set to a length corresponding to each flange portion 29, but the position, length, and number of outer peripheral portions 25 are not limited. In this embodiment, each outer peripheral portion 25 consists of a first outer peripheral portion 26 and a second outer peripheral portion 27 located radially outward from the first outer peripheral portion 26 and provided continuously with the first outer peripheral portion 26 along the circumferential direction.

[0026] In the plan view shown in Figure 4, if the direction along the line passing through the circumferential center of the support portion 28 and the center point P of the annular holder 20 is defined as the transverse direction, and the direction perpendicular to the transverse direction is defined as the vertical direction, then two first outer peripheral portions 26 are provided on one side and the other side of the transverse line L2, for a total of four first outer peripheral portions 26, which are positioned symmetrically with respect to the vertical line L1 and the transverse line L2. Adjacent first outer peripheral portions 26 are arranged with a predetermined interval L3 in the circumferential direction. Alternatively, one first outer peripheral portion 26 may be provided on one side and the other side of the transverse line L2. In this case, the circumferential length of the first outer peripheral portion 26 is the sum of the circumferential lengths of two adjacent first outer peripheral portions 26 in Figure 4 and the predetermined interval L3.

[0027] As shown in Figure 3, the first outer periphery 26 has a trapezoidal shape in side view, with the lower side being larger than the upper side, and a ridge 26a is formed on its outer surface extending radially outward. The ridge 26a is formed at the central part in the vertical direction and at both ends in the circumferential direction, extending along the circumferential direction. At the upper end of the outer surface of the first outer periphery 26, in the central part in the circumferential direction, a locking projection 26b is formed that engages with the locking hole 27b of the second outer periphery 27 of the other holder member 21.

[0028] The second outer periphery portion 27 is formed to slightly overlap the first outer periphery portion 26 in the circumferential direction. As shown in Figure 4, in a plan view, two second outer periphery portions 27 are provided on one side and two on the other side of the vertical line L1, for a total of four second outer periphery portions 27, which are positioned symmetrically with respect to the vertical line L1 and the horizontal line L2. Adjacent second outer periphery portions 27 are arranged with a predetermined gap L4 in the circumferential direction.

[0029] As shown in Figures 3 and 5, the second outer periphery 27 is rectangular in shape and is shorter in the vertical direction than the first outer periphery 26. In this embodiment, the vertical length of the second outer periphery 27 is approximately half the vertical length of the first outer periphery 26. The upper surface 27a of the second outer periphery 27 is continuous with the upper surface 26c of one of the protruding portions 26a of the first outer periphery 26, and their vertical positions are the same. A locking hole 27b is formed at the lower end of the circumferential center of the second outer periphery 27, which engages with the locking projection 26b of the first outer periphery 26 of the other holder member 21.

[0030] The support portion 28 extends upward from the radial inner edge of the upper surface of the first piece portion 23 of the base portion 22, and as shown in Figure 4, two support portions are provided in point-symmetrical positions in a plan view. In this embodiment, as shown in Figure 5, each support portion 28 is provided between adjacent second outer peripheral portions 27 in a side view, and its circumferential length is shorter than the distance L4 between adjacent second outer peripheral portions 27. The vertical length of the support portion 28 is set to be longer than the vertical length of the second outer peripheral portion 27 and shorter than the vertical length of the first outer peripheral portion 26. The circumferential length and vertical length of the support portion 28 are not limited to this embodiment.

[0031] As shown in Figure 2, the support portion 28 has a roughly L-shaped cross-section and is continuous with the base portion 22. It has a lower plate portion 28a that is inclined inward in cross-sectional view and an upper plate portion 28b that is inclined outward from the upper end of the lower plate portion 28a. The upper part of the lower plate portion 28a and the lower part of the upper plate portion 28b form a bent portion 28c. The distance between the upper ends of the lower plate portions 28a of opposing support portions 28, i.e., the distance between the bent portions 28c, is smaller than the inner diameter of the base portion 22 or the diameter of the first impregnated body 30 when the first impregnated body 30 is not located between the opposing support portions 28. As shown in Figure 2, the first impregnated body 30 is inserted so that its circumferential surface abuts against the bent portions 28c of the support portion 28. This causes a force from the first impregnated body 30 to act on the support portion 28, widening the distance between the bent portions 28c. The resulting biasing force of the support portion 28 acts on the first impregnated body 30, and the support portion 28 supports the first impregnated body 30.

[0032] (1st impregnated body 30) As shown in Figures 1 and 2, the first impregnated body 30 is cylindrical in shape, and its diameter L5 is slightly smaller than the inner diameter L6 of the base 22, and is set to a length that allows the upper or lower end of the first impregnated body 30 to be accommodated inside the base 22. The first impregnated body 30 has a hollow portion 31 that penetrates axially, and recesses 33 are formed around the hollow portion 31 at the center of the upper and lower surfaces. The upper and lower outer peripheral ends of the first impregnated body 30 are chamfered inclined surfaces 32. The first impregnated body 30 can be any porous material that is oil-absorbing and / or water-absorbing, and can be formed from, for example, ceramic, calcium silicate, activated carbon, zeolite, silica gel, cork, etc.

[0033] (Second impregnated body 35) As shown in Figures 1 and 2, the second impregnated body 35 has a circular sheet shape in plan view. In this embodiment, the thickness (length in the vertical direction) of the second impregnated body 35 is set to approximately half the length from the upper end of the second piece 24 of the base 22 to the upper surface of the flange 29, and the diameter of the second impregnated body 35 is set to be the same as the diameter L5 of the first impregnated body 30, but it is not limited to this. The second impregnated body 35 can be made of porous fibers that have oil absorption and / or water absorption properties, and in this embodiment, a nonwoven fabric made of artificial fibers such as nylon, polyester, and polypropylene is used as the material, but it is not limited to this.

[0034] (Seal part 40) The sealing portion 40 is a film sized to cover the opening 14 of the container 11, and maintains airtight and liquid-tightness inside the container 11 when the sealing portion 40 is provided on the container 11. At least the adhesive surface of the sealing portion 40 to the upper surface 13a of the peripheral wall 13 of the container 11 is made of a synthetic resin material such as polyethylene, polypropylene, ethylene, or vinyl acetate copolymer, and the entire sealing portion 40 may be made of these materials. The sealing portion 40 is bonded to the upper surface 13a of the peripheral wall 13 of the container 11 by heat, ultrasonic welding, or adhesive, with an adhesive strength that allows an operator to peel the sealing portion 40 off the container 11 by hand. Known configurations are used for the sealing portion 40.

[0035] (Cap 50) The cap 50 has a circular lid portion 51 in plan view and a peripheral wall portion 52 extending from the outer edge of the lid portion 51, and is sized to fit over the opening 14 of the container 11 and be locked to the container 11. Multiple vents 53 are formed in the lid portion 51 for the passage of volatile liquid. The number and size of the vents 53 are not limited, but in this embodiment, eight vents 53 are provided at equal intervals in the circumferential direction. Multiple engaging protrusions 54 are formed on the inner surface of the peripheral wall portion 52 at predetermined intervals in the circumferential direction. As the cap 50 deforms, the engaging protrusions 54 engage with the engaging protrusions 16 of the container 11, and the cap 50 is attached to the container 11.

[0036] (Assembly structure of the chemical disperser 10) The assembly structure of the chemical solution vaporizer 10 will now be described. First, the structure of the holder 20 that holds the first impregnated body 30 and the second impregnated body 35 will be described. As shown in Figure 6, the second holder member 21B is superimposed on the first holder member 21A in an inverted state relative to the first holder member 21A, and rotated 90 degrees around the center point P of the holder 20 relative to the first holder member 21A.

[0037] As shown in Figure 7, the tip of the first outer circumference 26B of the second holder member 21B is inserted inside the second outer circumference 27A of the first holder member 21A, and the upper surface 27a of the second outer circumference 27A of the first holder member 21A and the upper surface 26c of the protruding portion 26a of the first outer circumference 26B of the second holder member 21B come into contact, thereby positioning the second holder member 21B relative to the first holder member 21A. The locking projection 26b of the first outer circumference 26B of the second holder member 21B is locked into the locking hole 27b of the second outer circumference 27A of the first holder member 21A, thereby connecting the first and second holder members 21A and 21B to each other.

[0038] Furthermore, as shown in Figure 8, the tip of the first outer circumference 26A of the first holder member 21A is inserted inside the second outer circumference 27B of the second holder member 21B, and the upper surface 26c of the protruding portion 26a of the first outer circumference 26A of the first holder member 21A and the upper surface 27a of the second outer circumference 27B of the second holder member 21B come into contact, thereby positioning the second holder member 21B relative to the first holder member 21A. The locking projection 26b of the first outer circumference 26A of the first holder member 21A is locked into the locking hole 27b of the second outer circumference 27B of the second holder member 21B, thereby connecting the first and second holder members 21A and 21B to each other.

[0039] As shown in Figures 2, 6 to 8, when the first and second holder members 21A and 21B are stacked on top of each other, a housing space S is formed inside the first and second holder members 21A and 21B to accommodate the first impregnated body 30 and the second impregnated body 35. With the first holder member 21A in the lower position, the second impregnated body 35 is housed inside the base portion 22A of the first holder member 21A. The second impregnated body 35 is supported by the flange portion 29A. The first impregnated body 30 is placed above the second impregnated body 35. The lower surface of the first impregnated body 30 is in contact with the second impregnated body 35. The flange portion 29B of the upper second holder member 21B is in contact with the upper surface of the first impregnated body 30, supporting the first impregnated body 30.

[0040] The support portions 28A and 28B of the first and second holder members 21A and 21B respectively support the first impregnated body 30 by biasing force. Since the second holder member 21B is rotated 90 degrees relative to the first holder member 21A, the first impregnated body 30 is supported by a total of four support portions 28A and 28B, which are provided at 90-degree intervals around the center point P of the holder 20. The first impregnated body 30 is fixed in the space inside the holder 20 by contact with the support portions 28A and 28B, the flange portion 29B of the second holder member 21B, and the inner surface of the base portion 22 of the first and second holder members 21B, thereby preventing the first impregnated body 30 from moving.

[0041] As shown in Figures 2, 7, and 8, the holder 20 having the above structure is housed inside the container 11. The bottom surface of the first piece 23A of the base 22A of the first holder member 21A of the holder 20 abuts against the upper surface of the rib 15 provided at the bottom of the container 11, thereby positioning the holder 20 inside the container 11. The container 11 contains a liquid chemical, which is impregnated into the first impregnating body 30 and the second impregnating body 35. A seal portion 40 is adhered to the upper surface 13a of the peripheral wall 13 of the container 11, and a cap 50 is placed over the container 11 so as to cover the seal portion 40.

[0042] (Assembling method) The assembly method of the chemical disperser 10 will now be described. First, the holder 20 containing the first impregnated body 30 and the second impregnated body is assembled. The second impregnated body 35 is placed in the first holder member 21A, the first impregnated body 30 is placed on top of the second impregnated body 35, and the second holder member 21B is placed on top of the first holder member 21A. Next, the holder 20 is placed inside the container 11 with the first holder member 21A facing downwards. The holder 20 is placed on the ribs 15 of the container 11. Then, a predetermined amount of liquid is injected into the container 11, and the seal portion 40 is attached to the container 11. Next, the cap 50 is attached to the container 11. This completes the assembly of the chemical disperser 10. The chemical injected into the container 11 is absorbed by the first impregnated body 30 and the second impregnated body 35.

[0043] (Use of chemical disperser 10) When a user uses the chemical volatilization device 10 of the present invention, they first remove the cap 50 and the seal portion 40 that covers the opening 14 of the container 11, and then put the cap 50 back onto the container 11. The chemical mainly volatilizes from the first impregnated body 30 and is dispersed to the outside through the opening 14 of the container 11 and the vent hole 53 of the cap 50. After using it in this state for a certain period of time, the chemical impregnated in the upper part of the first impregnated body 30 will volatilize and decrease, so the user removes the holder 20 from the container 11, inverts the holder 20 upside down, and puts it back into the container 11. As a result, the lower parts of the second impregnated body 35 and the first impregnated body 30 are in an upward position, making it easier for the liquid impregnated in the second impregnated body 35 and the first impregnated body 30 to volatilize.

[0044] According to the above configuration, a holder 20 holding a first impregnated body 30 that can be inverted is housed in a bottomed container 11, allowing for a simple container 11 structure while reliably volatilizing the chemical solution. Furthermore, since the holder 20 is composed of a pair of holder members 21 of the same shape, there is no need to prepare multiple members of different shapes, making manufacturing easy. Moreover, since the holder 20 has the same shape before and after inversion, it can be reliably placed back into the container 11 even after being removed from it. In addition, when assembling the chemical solution volatilizer 10, the second impregnated body 35 is located close to the bottom of the container 11, so the injected chemical solution is immediately absorbed into the second impregnated body 35, preventing the chemical from splashing outside the container 11.

[0045] Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the present invention. Figures 9 and 10 show other embodiments of the holder member 61. The holder 20 comprises a pair of first and second holder members 61A and 61B of the same shape, and when there is no need to particularly distinguish between the first and second holder members 61A and 61B, they are simply referred to as "holder member 61". In addition to the configuration of the holder member 21 of the embodiment shown in Figure 1, the holder member 61 further comprises an annular member 62 and a connecting member 63 that connects the annular member 62 and the flange portion 29, on the same plane as the flange portion 29. The annular member 62 is positioned so that its center point is the same as the center point P of the holder 20, and has the same thickness (vertical length) as the flange portion 29. The connecting member 63 is rod-shaped and has the same thickness (vertical length) as the flange portion 29. In this embodiment, four connecting members 63 are provided to connect the four flange portions 29 and the annular member 62. Each connecting member 63 is positioned at the location where the distance between the center of the circumferential length of the inner edge of each flange portion 29 and the annular member 62 is shortest. Other components are the same as those in the embodiment shown in Figure 1, and are therefore denoted by the same reference numerals and their description is omitted.

[0046] According to the embodiments shown in Figures 9 and 10, the annular member 62 and the connecting member 63 support the lower surface of the second impregnated body 35, thereby preventing the second impregnated body 35 from coming out from between the flange portions 29.

[0047] The dimensions, materials, shapes, and relative arrangements of components described or shown in the drawings as embodiments are not intended to limit the scope of the present invention, but are merely illustrative examples. For example, expressions describing relative or absolute arrangements such as "in a certain direction," "along a certain direction," "parallel," "orthogonal," "center," "concentric," or "coaxial" should not only describe such arrangements strictly, but also indicate a state of relative displacement with tolerances or angles or distances sufficient to achieve the same function. For example, expressions describing things as being the same, such as "identical," "equal," and "homogeneous," should not only describe a state of being strictly equal, but also indicate a state where tolerances or differences exist to the extent that the same function can be achieved. For example, expressions describing shapes such as square or cylindrical should not only describe shapes such as square or cylindrical in a geometrically precise sense, but also include shapes that include concave and concave parts or chamfered parts, to the extent that the same effect can be achieved. Expressions such as "equipped," "possessing," "possessing," "including," or "having" a single component are not exclusive expressions that exclude the existence of other components.
