Description

[Technical field]

[0001] The present invention relates to a volatilization device and a volatilization device kit that volatilize a volatile medicinal liquid, such as an aromatic agent. [Background technology]

[0002] The volatilization device includes, for example, a container that contains a medicinal liquid, a volatilizer that is inserted into the opening of the container, and a cover that covers the volatilizer. This type of volatilization device is distributed as a volatilization device kit by, for example, attaching a cap to the opening of the container that contains the medicinal liquid so as to seal it, fitting a cover over the cap, and packaging it together with the volatilizer in a box.

[0003] When starting to use this volatilization device, the cover and cap are removed, the volatilizer is inserted into the opening of the container, the tip of the volatilizer is immersed in the drug solution, and the cover is attached to the container so as to cover the rear end of the volatilizer protruding from the opening. The volatilizer is assembled, for example, by combining two pieces of cardboard in a cross shape. The cover has, for example, a plurality of axially extending slits at equal intervals in the circumferential direction as volatilization holes.

[0004] The liquid medicine contained in the container is sucked up to the outside of the container through the opening by the volatilizer. The liquid medicine sucked up by the volatilizer is evaporated to the outside of the volatilizer through the multiple slits in the cover. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2019-99194 A Summary of the Invention [Problem to be solved by the invention]

[0006] Increasing the number of slits in the cover or widening the slit width to increase the opening area of ​​the volatilization hole can increase the amount of air that comes into contact with the volatilization body and can improve the volatilization efficiency of the liquid medicine. On the other hand, increasing the number of slits or widening the slit width makes the volatilization body more visible from the outside of the volatilization device, which makes the volatilization device look worse.

[0007] In addition, when the container is distributed with the opening closed with a cap, as in the case of the above-mentioned volatilization device kit, the screw threads on the outer circumference of the neck of the container are exposed after the cap is removed. Therefore, if the number of slits in the cover is increased or the width of the slits is widened, the screw threads become more visible, which deteriorates the appearance of the volatilization device.

[0008] The present invention has been made in consideration of the above points, and aims to provide an volatilization device and an volatilization device kit that can improve the appearance without reducing the volatilization efficiency of the chemical solution. [Means for solving the problem]

[Diagram 5] FIG. 5 is a plan view of the peripheral wall of the cover of the volatilization device of FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 to 3, the volatilization device 10 includes a container 2, a volatilization body 4, and a cover 6. The volatilization device kit 10′ shown in FIG.

[0014] The container 2 contains a predetermined amount of volatile medicinal liquid Y, such as a fragrance. The volatilizer 4 sucks up the medicinal liquid Y to the outside of the container 2 and volatilizes it. The cover 6 covers the wide portion 46 and the hanging piece portion 48 at the rear end of the volatilizer 4. The cover 6 has a plurality of volatilization holes 62. The cap 8 seals the opening 27 of the container 2 containing the medicinal liquid Y. After the volatilization device 10 is assembled, the cap 8 is no longer necessary.

[0015] The container 2 is a so-called bottle-shaped container having a body 22, a shoulder 24, and a neck 26. The container 2 is made of, for example, glass. The container 2 can be made of other materials such as resin. The body 22 integrally has a substantially cylindrical peripheral wall 22a and a substantially disk-shaped bottom wall 22b that closes the axial lower end of the peripheral wall 22a.

[0016] The neck 26 is generally cylindrical and has a generally circular opening 27 at its upper end. The neck 26 has a screw thread 28 on its outer circumferential surface for screwing the cap 8. The shoulder 24 is integrally provided between the lower end of the neck 26 and the upper end of the body 22. The shoulder 24 is generally disk-shaped and connects the lower end of the neck 26 to the upper end of the body 22. The shoulder 24 is inclined downward toward the outside in the radial direction. A generally annular engagement step 23 for attaching the cover 6 is provided on the outer surface side between the upper end of the body 22 and the shoulder 24.

[0017] As shown in Fig. 4, the volatilizer 4 can be assembled by combining two plate-shaped liquid-absorbing members 41, 42 (plate-shaped members) made of, for example, cardboard in a cross shape. The assembled volatilizer 4 is shown in Fig. 2. The liquid-absorbing members 41, 42 have approximately the same structure except for the positions and shapes of the notches 41a, 42a. Therefore, here, one of the liquid-absorbing members 41 will be mainly described, and components that function in a similar manner will be given the same reference numerals, and a description of the other liquid-absorbing member 42 will be omitted.

[0018] The liquid-absorbing member 41 has a substantially rectangular shaft portion 44 which can be inserted into the container 2 through the opening 27 at the upper end of the container 2, a substantially rectangular wide portion 46 which is provided integrally with the upper end of the shaft portion 44, and two substantially rectangular hanging pieces 48, 48 which are provided integrally with the lower end of the wide portion 46. The liquid-absorbing member 41 also has a notch 41a for combining with the liquid-absorbing member 42.

[0019] The width of the shaft 44 in the direction perpendicular to the insertion direction is slightly smaller than the inner diameter of the opening 27 of the container 2. The length of the shaft 44 is such that the tip (lower end in the figure) of the shaft 44 contacts the inner surface of the bottom wall 22b of the container 2 in the state in which the volatilizer 4 is inserted into the opening 27 of the container 2 as shown in FIG.

[0020] Wide portion 46 has a width that prevents it from being inserted into opening 27, and the upper end of shaft portion 44 is integrally connected to the center of its lower end. The width of wide portion 46 is smaller than the inner diameter of a substantially cylindrical peripheral wall 64 of cover 6, which will be described later. The vertical height of wide portion 46 is such that the upper end of wide portion 46 does not come into contact with the inner surface of top wall 66 of cover 6 in the state shown in FIG. 3 in which volatilizer 4 is attached to container 2 and covered with cover 6.

[0021] The two hanging pieces 48 are spaced apart from each other and hung down integrally on either side in the width direction of the lower end of the wide portion 46. The outer edges of each hanging piece 48 in the width direction are aligned in a straight line with both width direction edges of the wide portion 46. The length by which each hanging piece 48 protrudes from the lower end of the wide portion 46 is such that the lower end of each hanging piece 48 does not come into contact with the shoulder portion 24 of the container 2 when the volatilizer 4 is inserted into the opening 27 of the container 2 as shown in FIG.

[0022] Between each of the hanging pieces 48 and the shaft 44, there is provided a substantially rectangular recess 47 for inserting and positioning the neck 26 of the container 2. In the state in which the volatilizer 4 is attached to the container 2 as shown in FIG. 3, the edge of each hanging piece 48 on the neck 26 side is spaced apart from the neck 26 (i.e., the screw thread 28).

[0023] The notch 41a of the liquid-absorbing member 41 extends from the upper end of the wide portion 46 to a position beyond the upper end of the shaft portion 44. The notch 41a is slightly curved. The width of the notch 41a is approximately the same as the thickness of the liquid-absorbing member 42. On the other hand, the notch 42a of the liquid-absorbing member 42 extends from the lower end to the upper end of the shaft portion 44, to halfway along the shaft portion 44. The notch 42a is also slightly curved. The width of the notch 42a is approximately the same as the thickness of the liquid-absorbing member 41.

[0024] When combining two liquid-absorbing members 41, 42, the upper end of the notch 41a of the liquid-absorbing member 41 is aligned with the lower end of the notch 42a of the liquid-absorbing member 42, and the two notches 41a, 42a are fitted together. At this time, the two members are combined with the liquid-absorbing member 41 and the liquid-absorbing member 42 in a position perpendicular to each other. When the two liquid-absorbing members 41, 42 are combined in this manner in a cross shape, the upper ends of the wide parts 46 of the two liquid-absorbing members 41, 42 are arranged on the same imaginary plane, and the lower ends of the shaft parts 44 of the two liquid-absorbing members 41, 42 are arranged on another imaginary plane, as shown in Fig. 2.

[0025] Since the notches 41a of the liquid-absorbing member 41 are curved, when the two liquid-absorbing members 41, 42 are combined as shown in Fig. 2, the wide portion 46 of the liquid-absorbing member 42 is slightly curved. Also, since the notches 42a of the liquid-absorbing member 42 are curved, when the two liquid-absorbing members 41, 42 are combined as shown in Fig. 2, the shaft portion 44 of the liquid-absorbing member 41 is slightly curved. This increases the rigidity of the volatilizer 4.

[0026] When the volatilizer 4 assembled as described above is inserted into the container 2, the four engagement claws 49 provided between the shaft 44 and the wide portion 46 of each of the liquid-absorbing members 41, 42 engage with the engagement groove 26a (see FIG. 3) provided on the inner surface of the upper end of the neck portion 26 of the container 2, and the volatilizer 4 is fixed to the container 2. In this state, the lower ends of the shafts 44 of the two liquid-absorbing members 41, 42 come into contact with the inner surface of the bottom wall 22b of the container 2. As a result, the tip of the shaft 44 of the volatilizer 4 is immersed in the medicinal liquid Y, and the medicinal liquid Y is sucked up by the volatilizer 4, starting the volatilization of the medicinal liquid Y.

[0027] The cover 6 is integrally provided with a substantially cylindrical peripheral wall 64 and a substantially disk-shaped top wall 66 provided at an axial upper end 65 of the peripheral wall 64. The outer diameter of the peripheral wall 64 is substantially the same as the outer diameter of the body 22 of the container 2, and when the cover 6 is attached to the container 2 as shown in FIG. 1, the outer shape of the volatilization device 10 becomes substantially cylindrical.

[0028] The peripheral wall 64 and the top wall 66 each have a plurality of volatilization holes 62. In this embodiment, the top wall 66 is also provided with the volatilization holes 62, but it is sufficient that the volatilization holes 62 are provided at least in the peripheral wall 64. The size and shape of the volatilization holes 62 are formed to a size and shape that prevents a person's finger from being inserted therethrough. The shape and layout of the volatilization holes 62 (i.e., the structure of the peripheral wall 64) will be described in detail later.

[0029] A substantially cylindrical edge 64a of a predetermined width is provided on the lower end 67 side of the peripheral wall 64, which overlaps with the outside of the engagement step 23 of the container 2. No volatilization holes 62 are provided in the edge 64a. The edge 64a is continuous around the entire circumference of the peripheral wall 64. A plurality of engagement claws 64b (see FIG. 3) that engage with the engagement step 23 of the container 2 are provided on the inner surface side of the edge 64a, spaced apart from one another in the circumferential direction.

[0030] The volatilization device kit 10' is distributed by sealing the opening 27 of the container 2 containing a predetermined amount of medicinal liquid Y with a cap 8, attaching a cover 6 to the container 2, and boxing the two liquid-absorbing members 41 and 42 together. When assembling the volatilization device 10, the cap 8 screwed onto the neck 26 of the container 2 is removed, and the shaft 44 of the volatilization body 4, which is a cross combination of the two liquid-absorbing members 41 and 42, is inserted into the opening 27 of the container 2, and the tip of the volatilization body 4 is immersed in the medicinal liquid Y. Furthermore, the cover 6 is placed on the container 2 so as to cover the rear end side of the volatilization body 4, and the engagement claw 64b of the cover 6 is engaged with the engagement step 23 of the container 2, and the cover 6 is attached to the container 2. This state is shown in FIG. 1.

[0031] The multiple volatilization holes 62 provided in the cover 6 function to take in air into the cover 6 and increase the volatilization efficiency of the medicinal solution Y sucked up by the volatilizer 4. On the other hand, if the opening rate of the volatilization holes 62 is made too large in order to increase the volatilization efficiency, the internal volatilizer 4 and the threads 28 of the neck 26 of the container 2 will be easily visible from the outside of the cover 6, which may deteriorate the appearance of the volatilization device 10 and impair its aesthetic appearance.

[0032] For example, when multiple slit-shaped volatilization holes extending in the axial direction are provided on the peripheral wall of the cover as in the conventional volatilization device described above, it is expected that the volatilization body 4 having many edges in the upper and lower directions, such as the volatilization body 4 of the volatilization device 10 of this embodiment, can be made difficult to see from the outside of the cover depending on the viewing angle. However, since the screw thread 28 provided on the neck 26 of the container 2 extends in the horizontal direction intersecting with the axial direction, the screw thread 28 is conspicuous in the slit-shaped volatilization holes extending vertically as in the conventional device. In particular, when the number of slit-shaped volatilization holes is increased or the width is increased, such a defect becomes more noticeable.

[0033] FIG. 5 is a diagram showing the peripheral wall 64 of the cover 6 of the volatilization device 10 of this embodiment laid out in a flat state. As described above, all remaining portions 80 of the peripheral wall 64 other than the volatilization holes 62 function as concealing portions that make it difficult to see structures inside the cover 6. In other words, by devising a shape of this concealing portion 80 to match the shape of the structure inside the cover 6, it is possible to make the structure inside the cover 6 difficult to see. Therefore, in this embodiment, the structure of the peripheral wall 64 of the cover 6 (i.e., the shape and layout of the multiple volatilization holes 62) is designed to have the shape shown in FIG. 5.

[0034] The concealing portion 80 of the peripheral wall 64 has a shape in which a plurality of first portions 86 shaped like leaves and a plurality of second portions 88 shaped like drops are partially connected. In other words, the plurality of volatilization holes 62 are provided between the plurality of first portions 86 and the plurality of second portions 88. The area of ​​the first portions 86 is larger than the area of ​​the second portions 88. A leaf vein pattern is formed on the surface of the first portions 86.

[0035] The first portions 86 and the second portions 88 are connected in a linear relationship in the axial direction (the vertical direction in the figure) of the peripheral wall 64. The connecting portions 87 connecting the first portions 86 and the second portions 88 are arranged in the circumferential direction (the horizontal direction in the figure) of the peripheral wall 64 with their top and bottom orientations staggered. In this embodiment, 14 connecting portions 87 are arranged in a staggered manner in the circumferential direction. The first portions 86 of two connecting portions 87 adjacent to each other in the circumferential direction are partially connected to each other in the circumferential direction. The upper end and the lower end of each connecting portion 87 are connected to the upper end 65 and the lower end 67 of the peripheral wall 64, respectively.

[0036] From another perspective, the blind portion 80 of the peripheral wall 64 includes a plurality of linear vertical portions and an annular horizontal portion. The vertical portions are portions of the peripheral wall 64 within a plurality of rectangular regions 82 that are elongated in the axial direction and are surrounded by dashed lines in Fig. 5, and each of the vertical portions includes a portion of the first portion 86 and a portion of the second portion 88, as well as including the circumferential center of each connecting portion 87. Hereinafter, this portion will be referred to as the vertical portion 82. Each vertical portion 82 is a continuous portion that linearly connects the upper end 65 and the lower end 67 of the peripheral wall 64 in the axial direction, and is a portion in which no volatilization holes 62 are provided.

[0037] The annular horizontal portion is a part of the peripheral wall 64 located within a rectangular region 84 extending in the circumferential direction and surrounded by a dashed line in Fig. 5, and is a portion that connects the first parts 86 of each connecting portion 87 in a circumferentially annular shape. Hereinafter, this portion will be referred to as the horizontal portion 84. The horizontal portion 84 is a portion that is continuous over the entire circumferential direction of the peripheral wall 64 at positions spaced apart from the upper end 65 and the lower end 67 of the peripheral wall 64, and is a portion in which the volatilization holes 62 are not provided. The horizontal portion 84 is provided at a position including the center between the upper end 65 and the lower end 67 of the peripheral wall 64.

[0038] In this embodiment, the top wall 66 of the cover 6 is also provided with a concealing portion having a shape similar to the above-mentioned connecting portion 87, but providing the volatilization holes 62 in the top wall 66 is not an essential configuration for the present invention. However, even when a plurality of volatilization holes 62 are provided in the top wall 66 as in this embodiment, the concealing effect of making the volatilization body 4 and the screw threads 28 less visible can be enhanced by devising the shape of the parts of the top wall 66 other than the volatilization holes 62.

[0039] The hiding effect provided by the vertical portion 82 and the horizontal portion 84 of the hiding portion 80 of the peripheral wall 64 will now be described.

[0040] For example, when the volatilization device 10 is viewed from the side of the cover 6, a part of the volatilization body 4 and a part of the screw thread 28 of the neck portion 26 may be visible from the outside through the multiple volatilization holes 62. However, since the peripheral wall 64 of the cover 6 has multiple vertical parts 82, when the vertical parts 82 exactly overlap a structure extending in the axial direction of the volatilization body 4 (for example, the radially outer edge of the wide part 46 of the liquid-absorbing members 41, 42), the structure in the axial direction becomes completely invisible, making it difficult to see the outer shape of the volatilization body 4. Even if the vertical parts 82 of the cover 6 do not exactly overlap a structure extending in the axial direction of the volatilization body 4, a part of the structure in the axial direction is necessarily hidden by the leaf-shaped first part 86 of the peripheral wall 64, making it difficult to see the volatilization body 4 from the outside.

[0041] However, since the screw thread 28 on the outer peripheral surface of the neck 26 of the container 2 is provided in a direction intersecting with the axial direction, even if only the vertical portion 82 of the peripheral wall 64 is seen overlapping the screw thread 28, the screw thread 28 would be easily visible from the outside. In addition, since the hanging piece portion 48 of the liquid-absorbing members 41, 42 overlapping the outer side of the screw thread 28 is a thin plate-like structure, almost no part of the screw thread 28 is hidden by the volatilizer 4.

[0042] In contrast, in the volatilization device 10 of this embodiment, the side portion 84 of the peripheral wall 64 of the cover 6 is provided continuously around the entire circumference of the peripheral wall 64, so that the screw threads 28 are partially hidden by this side portion 84 and are difficult to see from the outside. Since the side portion 84 is provided continuously around the entire circumference of the peripheral wall 64, the concealing effect of the side portion 84 can be obtained in the same way when the volatilization device 10 is viewed from any position in the circumferential direction.

[0043] Moreover, the hiding effect of the side portion 84 as described above can be enhanced by increasing the axial width W of the side portion 84. However, when the width W of the side portion 84 is increased, the volatilization hole 62 becomes smaller accordingly, and the volatilization efficiency of the medicinal liquid Y decreases. Therefore, in this embodiment, the width W of the side portion 84 is set to 1 / 8 to 1 / 3 of the axial length T of the peripheral wall 64 so that the volatilization efficiency of the medicinal liquid Y can be sufficiently satisfied while improving the appearance of the volatilization device 10.

[0044] Moreover, the concealing effect of the side portion 84 can be enhanced by providing the side portion 84 at an intermediate position between the upper end 65 and the lower end 67 of the peripheral wall 64. The cover 6 is attached to the container 2 by engaging the engagement claw 64b on the inner edge of the lower end of the peripheral wall 64 with the engagement step portion 23 between the body portion 22 and the shoulder portion 24 of the container 2. Therefore, when the cover 6 is attached to the container 2, the neck portion 26 of the container 2 faces a portion above the lower end of the peripheral wall 64 of the cover 6. Therefore, by providing the side portion 84 at an intermediate position in the vertical direction away from the upper end 65 and the lower end 67 of the peripheral wall 64, it is possible to make the threads 28 of the neck portion 26 less visible from the outside.

[0045] The concealing effect of the above-mentioned side portion 84 can be obtained not only when the volatilization device 10 is viewed from the side of the cover 6, but also when the volatilization device 10 is viewed from diagonally above (for example, as shown in FIG. 1). In addition, if the volatilization device 10 is placed on a shelf or the like and viewed from diagonally below, the threads 28 of the neck 26 are seen through the shoulder 24 of the container 2, making the threads 28 difficult to see.

[0046] As described above, in this embodiment, the concealing portion 80 of the peripheral wall 64 includes a plurality of vertical portions 82 and horizontal portions 84, so that the volatilizer 4 on the inside of the cover 6 and the screw threads 28 of the neck portion 26 are less visible from the outside through the volatilization hole 62 without reducing the volatilization efficiency of the medicinal solution Y, thereby improving the appearance of the volatilization device 10.

[0047] In addition, in the cover 6 of the volatilization device 10 of this embodiment, the volatilization holes 62 may appear to overlap depending on the circumferential position when the cover 6 is viewed from the outside in the radial direction. When the connecting part 87 that axially connects the first part 86 and the second part 88 of the blind part 80 is viewed with the vertical part 82 included in this connecting part 87 facing forward, another connecting part 87 facing the opposite side in the radial direction of the connecting part 87 has the first part 86 and the second part 88 connected upside down. Therefore, the volatilization holes 62 do not appear to overlap even when the cover 6 is viewed from this direction.

[0048] In contrast, when two circumferentially adjacent connecting parts 87 are regarded as one pattern and the cover 6 is viewed with this pattern facing forward, another pattern on the opposite side in the radial direction appears to overlap with the pattern on the front side. In other words, when the cover 6 is viewed from this direction, a plurality of volatilization holes 62 appear to overlap front and rear. In other words, when a cover 6 having a peripheral wall 64 that is continuous in the circumferential direction and has a pattern that can be seen to overlap front and rear like this is used, air can be effectively caused to flow inside the cover 6 through the volatilization holes 62, and the volatilization efficiency of the medicinal liquid Y can be improved. Such an effect is obtained when a volatilization body made of a plate-shaped member (for example, one of the liquid-absorbing members 41 and 42) is used instead of the cross-shaped volatilization body 4 of this embodiment, as air becomes more likely to flow in the surface direction of the volatilization body. The same can be said when a rod-shaped volatilization body is used.

[0049] The present invention is not limited to the above embodiment, and can be modified in various ways in the implementation stage without departing from the gist of the invention. The above embodiment includes various inventions, and various inventions can be extracted by combinations selected from the multiple components disclosed. For example, if the problem can be solved and an effect can be obtained even if some components are deleted from all the components shown in the embodiment, the configuration from which the components are deleted can be extracted as an invention.
