Description

  The present invention relates to a measuring cap and a container, and more particularly, a cap that is detachably attached to a mouth of a container body filled with a transparent liquid material, and that can measure the transparent liquid material almost accurately and easily. It relates to a container provided with.

  Many liquid products such as liquid cosmetics such as mouthwashes, liquid quasi-drugs, liquid pharmaceuticals such as gargles, detergents for laundry, home use, homes and furniture, etc. are bottle-shaped containers made of resin materials, etc. It is distributed in the market in the form filled in. The container is filled with a liquid substance and has a container body having a mouth part serving as a pouring spout for the liquid substance, and a scale and a letter symbol that are attached to the mouth part of the container body and serve as a standard for measuring the liquid substance on the inner side surface. And a cap provided. And a liquid substance is measured by removing a cap from the opening | mouth part of a container main body, pouring a liquid substance in the inside in an inverted state.

  The cap of the container filled with the liquid material with little quality deterioration due to light such as laundry detergent is mainly made of a transparent material, and the coincidence of the scale and the liquid level can be visually recognized relatively easily from the lateral direction of the cap. However, liquid cosmetics, liquid quasi-drugs, liquid pharmaceuticals, etc. are often filled in containers with caps made of opaque materials from the viewpoint of preventing quality deterioration due to light. Therefore, it is difficult to visually recognize the coincidence between the scale and the character symbols and the liquid level. In particular, when a transparent liquid material is measured with a cap made of an opaque material, it may be difficult to visually recognize the position of the liquid surface.

  Among liquid products, liquid cosmetics, liquid quasi-drugs, liquid pharmaceuticals, etc. are contained in the mouth, swallowed, or applied to the skin. It is not desirable to improve the visibility by opacifying or darkening these liquid materials. In addition, since the liquid dose is determined per one time, more accurate measurement is required than various detergents. Therefore, there is a demand for a measuring cap that can accurately and easily measure a transparent liquid material.

  Patent Document 1 discloses an inner cylinder in which a display window, which is a through hole, is provided on a side wall, and an outer cylinder that is provided in contact with an outer side surface of the inner cylinder and is colored in a color different from the inner cylinder. A measuring cylinder made of a body and a cap body integrally formed surrounding the measuring cylinder, and the inner side surface of the outer cylinder visible from the display window of the inner cylinder is different from the inner cylinder. A measuring cap that is configured to measure a liquid substance using the above is disclosed. However, even if different color regions are provided on the inner side surface of the cap, the visibility of the liquid surface of the transparent liquid material is not so improved.

  Patent Document 2 discloses a side wall that is a transparent cylinder, a bottom wall that is fitted to the lower end of the cylinder, and a colored cross-sectional step-shaped scale plate that protrudes from the bottom surface of the bottom wall along the inner side surface of the side wall. A measuring cap configured to measure by pouring a liquid material until the top surface of each step of the scale plate and the liquid level coincide with each other is disclosed. However, in the measuring cap, since the entire scale plate is colored and the scale plate is provided along the inner side surface of the side wall, the internal coloring area is too large, and the poured transparent liquid material is colored. Therefore, the visibility of the liquid level is not improved.

  FIG. 1 is a schematic diagram showing a schematic configuration of a measuring cap (hereinafter simply referred to as “cap”) 1 according to the first embodiment of the present invention. 1 to 19, (a) is a perspective view showing an external shape, (b) is a perspective view in an inverted state, and (c) is a cross-sectional perspective view in an inverted state. 2 to 19, members and regions common to the cap 1 are denoted by the same reference numerals as those in FIG. 1 and description thereof is omitted. The cap 1 includes a raised portion 13 having a top portion 13b that protrudes toward the opening portion 10 and is provided with a color region 14 on the entire surface of the top portion 13b.

  The cap 1 has a cylindrical shape with a bottom, a bottom wall 11 having an inner bottom surface 21 facing the opening 10 of the cap 1, and rises from a peripheral edge of the bottom wall 11, and a measuring mark 24 and A side wall 12 having a fitting portion 25 for attaching the cap 1 to a mouth portion (not shown) of the container main body and a part of the bottom surface 21 are raised toward the internal space of the cap 1 while being separated from the inner side surface 22. The raised portion 13, the color area 14 of the raised portion 13 on the opening 10 side (tip side) surface, which is colored in a color different from the inner side surface 22, and the cap 1 rising from the bottom surface 21 so as to surround the raised portion 13 And a seal ring 15 that is an annular member that abuts around the mouth portion to prevent liquid leakage when the container is attached to the mouth portion of the container body.

  The cap 1 is detachably attached (fixed and fitted) to a mouth part which is a spout of a container body (not shown) filled with a transparent liquid material, and is removed from the mouth part to be inverted to be transparent liquid. It has a function of measuring a predetermined amount of liquid by pouring things. The outer shape of the cap 1 is not limited to a bottomed cylindrical shape, and may be any shape such as a bottomed polygonal shape.

  The material constituting the container body having the cap 1 and the mouth may be either a transparent material or an opaque material. However, from the viewpoint of suppressing deterioration of the transparent liquid material due to light, the material is mainly composed of a resin material, a glass material, or the like. An opaque material is preferred. The liquid material is not particularly limited as long as it is transparent. For example, liquid cosmetics such as mouthwash, liquid quasi-drugs, liquid pharmaceuticals such as gargles, liquid pesticides, laundry, household, furniture and buildings And various detergents. When the transparent liquid is liquid cosmetics, liquid quasi-drugs, liquid pharmaceuticals, etc., it is possible to measure the determined dose almost accurately and easily, so that unnecessary use beyond the dose can be suppressed.

  Although the bottom wall 11 is substantially circular in this embodiment, the shape is not particularly limited, and may be, for example, a polygonal shape such as a triangle, a quadrangle, a hexagon, or an octagon.

  The inner side surface 22 of the side wall 12 is entirely the same color in this embodiment. From the viewpoint of improving the visibility of the liquid surface in the vicinity of the boundary between the inner side surface 22 and the liquid surface, the inner side surface 22 is preferably substantially white. The measurement mark 24 is a scale extending linearly in the circumferential direction on the inner side surface 22 near the opening 10. In this embodiment, two lines are used, but one or three or more lines may be used. The fitting part 25 is a screw thread. The cap 1 is attached to the mouth portion by screwing this with the screw thread on the outer side surface of the mouth portion. Further, in order to facilitate attachment and detachment from the mouth portion of the cap 1, at least one selected from a concave portion and a convex portion (both not shown) having an arbitrary shape is placed at an arbitrary position on the outer side surface 23 of the side wall 12. For example, the outer side surface 23 may be provided at a predetermined interval in the circumferential direction or in a direction perpendicular to the circumferential direction.

  The raised portion 13 protrudes from the center of the bottom surface 21 coaxially with the bottom wall 11 while being separated from the seal ring 15 and the inner side surface 22, and is substantially flat with a substantially cylindrical base portion 13a and a slightly smaller diameter than the base portion 13a. It has a dome (hemisphere) -like top portion 13b having a flat top surface. The base portion 13a is not limited to a cylindrical shape, and can be an arbitrary shape such as a prismatic shape. In the present embodiment, the entire surface of the top portion 13 b that is the opening 10 side (tip side) portion of the raised portion 13 is colored in a color different from that of the inner side surface 22, thereby forming a color region 14. The color region 14 is substantially circular when viewed from above. The color region 14 is located higher than the upper end of the seal ring 15 with respect to the bottom surface 21.

  The color of the color region 14 is not particularly limited, but is preferably darker than the inner side surface 22 from the viewpoint of improving the visibility of the liquid level. The color density is defined as saturation and can be measured with a saturation meter or the like. The color of the color region 14 is not particularly limited, but when a liquid cosmetic, liquid quasi-drug or liquid pharmaceutical is used as the transparent liquid, a viewpoint that it is uncomfortable to include in the mouth if it looks an unusual color. From the viewpoint of improving the visibility of the liquid level, for example, green, red, orange, blue, light blue and the like are preferable. Further, the color region 14 may be dyed with a plurality of different colors. At this time, by making the color of the inner side surface 22 substantially white, the visibility and the meterability of the liquid level are further improved.

  By providing the color region 14, the entire transparent liquid material in the cap 1 appears to be lightly colored in the same color as the color region 14 from any position of the opening 10, and in the vicinity of the boundary with the inner side surface 22. Since the liquid level looks darker than other parts, the visibility and meterability of the liquid level are significantly improved.

  The seal ring 15 is separated from the raised portion 13 on the inner side and is separated from the inner side surface 22 on the outer side. When the cap 1 is attached to the mouth portion of the container body, the tip portion of the mouth portion is inserted between the raised portion 13 and the seal ring 15, and the mouth portion is brought into contact with the seal ring 15 around the mouth portion. Is sealed and liquid leakage from the container body is prevented. In this embodiment, the height of the seal ring 15 is set so that the upper end of the seal ring 15 is lower than the top portion 13b where the color region 14 of the raised portion 13 is provided. The effect becomes remarkable.

  In the present embodiment, the boundary portion between the bottom wall 11 and the side wall 12 is a gently curved surface (substantially fan-shaped in cross section) on both the inside and the outside, but is not limited to this. The side wall 12 may be configured to rise substantially vertically.

  The size of the cap 1 is appropriately selected according to the filling amount of the transparent liquid material set in the container body (not shown), the dimensions of the container body, and the like. Is about 20 to 50 mm, preferably about 25 to 35 mm, and the height is about 2 to 5 cm, preferably about 2.5 to 4.5 cm. Thereby, for example, a transparent liquid substance of about 10 to 40 ml can be easily measured. Moreover, the cap 1 can be produced using, for example, a two-color molding method. Even if the cap 1 is manufactured by attaching the color region 14 to a cap body having the above-described configuration other than the color region 14 by using an appropriate means such as adhesion, fitting, and thermal welding. Good. In this case, the color region 14 is in the form of a colored packing or the like made of a resin material, a rubber material, an elastomer material, or the like.

  According to the cap 1, the entire transparent liquid material poured into the cap 1 appears to be lightly dyed in the same color as the color region 14, and only the liquid surface near the boundary between the inner side surface 22 and the liquid surface is the color region 14. By forming an annular region having a dark color and a dark color, the visibility of the liquid level in contact with the inner side surface 22 is remarkably improved, and the liquid level is very consistent with the position of the measurement mark 24. To be easier. As a result, the predetermined liquid amount of the transparent liquid can be measured almost accurately and very easily.

  2-7 is a schematic diagram which shows schematic structure of the caps 1A, 1B, 1C, 1D, 1E, 1F which are the modifications of the cap 1 which is 1st Embodiment, respectively. Each of the caps 1 </ b> A to 1 </ b> F includes a raised portion having a top portion protruding toward the opening portion 10, and a color region having the same configuration as the color region 14 of the cap 1 is provided on the top portion. Similar effects can be achieved. Although the measurement marks are not shown in FIGS. 2 to 6, the measurement marks are actually provided at the same position as the cap 1.

  The cap 1A shown in FIG. 2 has a substantially cylindrical base portion 30a, a dome (hemisphere) -like top portion 30b that protrudes toward the opening 10 following the base portion 30a, and an entire surface of the top portion 30b. It has a color area 31 provided. The height of the base portion 30 a of the raised portion 30 (height with respect to the bottom surface 21, hereinafter the same) is substantially the same as that of the seal ring 15, and the top portion 30 b and the color region 31 provided on the surface thereof are more than the seal ring 15. High position. The cap 1 </ b> B shown in FIG. 3 has a dome-shaped raised portion 32 having a height lower than that of the seal ring 15 and a color region 33 provided on the entire surface of the raised portion 32.

  The cap 1C shown in FIG. 4 includes a raised portion 34 composed of a substantially cylindrical base portion 34a and a dome (hemisphere) -like top portion 34b following the base portion 34a, a color region 35 provided on the entire surface of the raised portion 34, and Further, two annular steps 26 extending substantially linearly in the circumferential direction of the inner side surface 22 are provided below the measurement mark. In this embodiment, the top 34b of the raised portion 34 is higher than the seal ring 15. However, a part of the top 34b may be higher than the seal ring 15, and the raised portion 34 and the seal ring 15 may be It may be almost the same height.

  The annular step 26 has a horizontal plane 26a that is substantially parallel to the bottom surface 21, and the reflected light from the color region 35 is difficult to reach the horizontal plane 26a. For this reason, when the level difference 26 is lower than the liquid level, the level difference 26 is not colored and the effect of appearing to float in the liquid is obtained, and the level difference 26 is very easy to visually recognize. . On the other hand, the effect that only the liquid surface near the boundary with the inner side surface 22 appears to be darkly colored is the same as that of the cap 1 or the like. Accordingly, by providing the step 26 below the measurement mark on the inner side surface 22 as in the present embodiment, the visual recognition of the step 26 serves as a notice function of the end of the measurement, which improves the liquid level visibility. It enables accurate and easy weighing. The same effect can be obtained by providing a slope instead of the horizontal surface 26a. Further, the number of steps is not limited to two, and may be one or three or more.

  The cap 1D shown in FIG. 5 is provided on the entire surface of the top portion 36b, and a raised portion 36 composed of a substantially cylindrical base portion 36a and a conical top portion 36b protruding to the opening 10 side following the base portion 36a.

In the present embodiment, the height of the base portion 36 a of the raised portion 36 is substantially the same as that of the seal ring 15, and the top portion 36 b and the color region 37 provided on the surface thereof are higher than the seal ring 15. A part of the top part 36b may be higher than the seal ring 15, and the raised part 36 may be the same height as the seal ring 15 or lower than the seal ring 15. However, the effect of the present invention is sufficiently obtained. Therefore, it is preferable that the color region 37 is located higher than the seal ring 15 as in the present embodiment.

  The cap 1E shown in FIG. 6 is provided on the entire surface of the top portion 38b and a raised portion 38 formed of a substantially cylindrical base portion 38a, and a pentagonal pyramid-like top portion 38b projecting to the opening 10 side following the base portion 38a. Color region 39 is provided. In this case, the cross-sectional shape of the truncated pyramid constituting the apex 38b is not limited to a pentagon, and may be an arbitrary polygon such as a triangle, a quadrangle, or a hexagon. The shape of the top portion 38b is not limited to a truncated pyramid shape, and may be an arbitrary shape such as a truncated cone shape. The height of the raised portion 38 is substantially the same as that of the seal ring 15, but is not limited to this, and may be higher or lower than the seal ring 15.

  A cap 1F shown in FIG. 7 has the same configuration as the cap 1 and is characterized in that the measurement mark 24 is a groove extending in an annular shape along the circumferential direction on the inner side surface 22. Thus, by providing the concave measurement mark 24 on the inner side surface 22, when the transparent liquid material is poured into the cap 1F, the entire liquid material appears to be lightly dyed in the color area 14, In addition, only the liquid level near the boundary with the inner side surface 22 appears to be darkly dyed in the color of the color region 14, and the groove itself is dyed more deeply than the liquid level near the boundary so that it can be seen very clearly. Become. Accordingly, the position of the measurement mark 24 is remarkably easily understood, and the measurement performance is greatly improved.

  In the present embodiment, one annular groove is provided. However, the present invention is not limited to this, and an arbitrary number of one or more grooves can be provided, and a plurality of short grooves can be provided at predetermined intervals. May be provided in the circumferential direction of the inner side surface 22, and a groove having a predetermined length extending in the circumferential direction of the inner side surface 22 may be provided in part. In addition, although the cross-sectional shape of a groove | channel is not specifically limited, From viewpoints, such as easiness of formation, semicircle shape, square shape, etc. are preferable.

  FIG. 8 is a schematic diagram showing a schematic configuration of the cap 2 according to the second embodiment of the present invention. 9 to 11 are schematic diagrams illustrating schematic configurations of modified examples 2A to 2C of the cap 2, respectively. Although the measurement mark 24 is not shown in FIGS. 9 to 11, the measurement mark is actually provided at the same position as the cap 2.

  Each of the caps 2, 2A, 2B shown in FIGS. 8 to 10 is provided on the substantially columnar raised portion 40 and the entire top surface 40a in which the top surface 40a is a flat surface substantially parallel to the bottom surface 21. A color area 41 is provided. The raised portion 40 is higher than the seal ring 15 in the cap 2, is almost the same height as the seal ring 15 in the cap 2A, and is lower than the seal ring 15 in the cap 2B. Even if it is configured as the caps 2, 2A to 2B, the same effect as the cap 1 can be obtained. Among these, from the viewpoint of improving the visibility of the liquid level in the vicinity of the boundary between the inner side surface 22 and the liquid level, the caps 2 and 2A are preferable, and the cap 2 is more preferable.

  A cap 2C shown in FIG. 11 has a substantially cylindrical raised portion 42 having a top surface 42a that is a substantially flat slope inclined with respect to the bottom surface 21, and a color region 43 provided on the entire top surface 42a. . Since the color region 43 is partly higher than the seal ring 15 and the other part is lower than the seal ring 15, the liquid surface near the boundary with the inner side surface 22 seems to be darkly colored over the entire circumference. Rather than appearing, it appears that almost half of the circumference is darkly colored. For this reason, since it becomes easy to visually recognize the movement of the deeply colored liquid surface from the contrast with the non-colored portion, the visibility and the meterability can be improved.

  FIG. 12 is a schematic diagram showing a schematic configuration of the cap 3 according to the third embodiment of the present invention. 13 to 15 are schematic diagrams illustrating schematic configurations of modified examples 3A to 3C of the cap 3, respectively. Although the illustration of the measurement mark 24 is omitted in FIGS. 13 to 15, the measurement mark is actually provided at the same position as the cap 3.

The cap 3 </ b> A shown in FIG. 13 is provided with a color area 45 in the entire area surrounded by the seal ring 15 on the bottom surface 21. As described above, when the color regions 44 and 45 are directly provided without providing the raised portion on the bottom surface 21, only the liquid surface in the vicinity of the boundary with the inner side surface 22 is colored, and the color intensity is slightly reduced. However, the visibility of the liquid level is reliably improved as compared with the case where the color regions 44 and 45 are not provided. In the present embodiment, only the bottom surface 21 is set as the color regions 44 and 45, but the present invention is not limited to this, and a color region may be provided on the bottom surface 21 and the inner side surface 22 in the vicinity thereof. Examples of the color region provided on the inner side surface 22 include an annular color region and a color region in which a plurality of color region fragments are arranged in the circumferential direction with a predetermined interval.

  The cap 3B shown in FIG. 14 is provided with a color region 46 on the entire region surrounded by the seal ring 15 on the bottom surface 21 and on the entire inner side surface 15a of the seal ring 15, and has an annular shape with a predetermined width from the upper end portion of the inner side surface 22. A colored region 27 is provided. The width of the annular colored region 27 is not particularly limited, and may be configured such that a measurement mark exists in the region 27 as in this embodiment, and the measurement mark exists at the upper end of the region 27. You may comprise. By providing the region 27 having a width in the vertical direction on the inner side surface 22, the liquid surface appears to be discolored while the transparent liquid material is being poured, so that a notice function of the end of measurement can be obtained. In the present embodiment, the inner side surface 15a of the seal ring 15 is a part of the color region 46. However, the present invention is not limited to this, and the inner side surface 15a may not be a color region and only the bottom surface 21 may be a color region.

  In the present embodiment, the color region 46 and the annular colored region 27 may be the same color or different colors, and in the case of the same color, they may be the same darkness or different darkness, but are preferably different colors from the viewpoint of visibility. The color region 46 is more preferably a different color and a darker color than the annular colored region 27. When the color region 46 and the annular colored region 27 have different colors, the liquid surface appears to be changed to a third color obtained by mixing two colors, thereby improving visibility. For example, if the color area 46 is yellow and the annular colored area 27 is green, the liquid surface looks darker blue-green than these, and the visibility is improved.

  The cap 3C shown in FIG. 15 is provided so as to be in contact with the surface of the color region 45 and separated from the inner side surface 15a of the seal ring 15 in the entire region surrounded by the seal ring 15 on the bottom surface 21. A cylindrical transparent member 28. The cylindrical transparent member 28 is used when the cap 3C is attached to the mouth portion (not shown) of the container body without impairing the effect of the present invention in which only the liquid surface near the boundary with the inner side surface 22 appears to be darkly colored. The airtightness between the cap 3C and the mouth portion can be improved. The top surface 28a of the cylindrical transparent member 28 is a flat surface substantially parallel to the bottom surface 21 in the present embodiment, but is not limited thereto, and may be a convex surface, a concave surface, a slope, or the like.

  FIG. 16 is a schematic diagram showing a schematic configuration of the cap 4 according to the fourth embodiment of the present invention. FIGS. 17-19 is a schematic diagram which shows schematic structure of the modification 4A, 4B, 4C of the cap 4, respectively.

  The cap 4 shown in FIG. 16 is provided with a color region 45 in the entire region surrounded by the seal ring 15 on the bottom surface 21, and two annular steps 26 are provided as measurement marks 24 on the inner side surface 22. According to the cap 4, only the liquid surface in the vicinity of the boundary with the inner side surface 22 appears to be darkly colored, and the horizontal surface 26a of the annular step 26 is not colored and appears to float in the liquid. It is done. Therefore, if the horizontal plane 26a located on the upper stage side of the two horizontal planes 26a is set as the measurement target, the function of notifying the end of the measurement is achieved that the horizontal plane 26a located on the lower stage side appears to float in the liquid. Therefore, more accurate weighing becomes possible.

  In the present embodiment, the annular step 26 is provided. However, the present invention is not limited to this. For example, a plurality of step pieces having a predetermined length may be provided at predetermined intervals in the circumferential direction of the inner side surface 22. You may provide the step piece of predetermined length only in a part of direction. In the present embodiment, the step 26 having two steps is provided. However, the present invention is not limited to this, and an arbitrary number of steps of one or more steps can be used. Even if the level difference is one level, if the position of the liquid surface where the level difference starts to appear is set as the measurement target, almost accurate measurement is possible. Moreover, in this embodiment, although the level | step difference 26 which has the horizontal surface 26a is provided, you may provide the level | step difference which has a slope.

  The cap 4 </ b> A shown in FIG. 17 has the measurement marks 24 in which one step 47 and slopes 48 are alternately arranged in the circumferential direction of the inner side surface 22. A plurality of slits 47 a that are recessed in a direction substantially perpendicular to the direction in which the step 47 extends are formed in the first step 47. When a transparent liquid material is poured into the cap 4 </ b> A, the plurality of slits 47 a formed in the step 47 can be visually recognized in the same color as the color region 45, while the slope 48 is colored in the color region 45. Therefore, from this contrast, the coincidence between the horizontal surface and the liquid level of the step 47 can be easily visually recognized, and the meterability is improved.

  The cap 4 </ b> B shown in FIG. 18 has a one-step step 49 that extends substantially linearly in the circumferential direction of the inner side surface 22 as the measurement mark 24. A plurality of slits 49 a that are recessed in a direction substantially perpendicular to the extending direction of the step 49 are formed in the first step 49 over the entire circumference of the step 49. Since the slit 49a exhibits the same effect as the slit 47a, the coincidence between the step 49 and the liquid level can be easily visually recognized, and the meterability is improved.

A cap 4C shown in FIG. 19 has a one-step step 50 having a horizontal plane 50a that is substantially right-angled in cross section and substantially parallel to the bottom surface 21, and a slope 51 in which the numeral symbol “10” is recessed is formed on the inner side surface. The measurement marks 24 are alternately arranged in the circumferential direction of 22. When a transparent liquid material is poured into the cap 4C, the first step 50 and the slope 51 are not colored in the color region 45, but the numeral symbol “10” is recessed in the slope 51, so that it is dark and clear. It looks colored. For this reason, the coincidence between the numeral symbol “10” and the liquid level can be easily visually recognized, and the meterability is improved.
Note that the color area in each of the above-described embodiments can adopt the same configuration as the color area 14.

  A container according to another embodiment of the present invention is a container body for filling a liquid material having a mouth part for pouring a transparent liquid material into a cap, and is detachably attached to the mouth part via a fitting means. And the cap is the cap of the present invention described above.

  The liquid material filled in the container of the present invention is not particularly limited as long as it is transparent. For example, liquid cosmetics such as mouthwash, liquid quasi-drugs, liquid pharmaceuticals such as mouthwashes, liquid pesticides, laundry For example, liquid detergents, liquid pharmaceutical quasi-drugs, liquid pharmaceuticals and the like are preferable.

  In the container of the present invention, the cap of the present invention having the above-described color region is inverted and used for measuring a transparent liquid material, so that the visibility of the liquid level is improved and the predetermined liquid amount is almost accurately and easily obtained. Can be measured. The container of the present invention may be composed of either a transparent material or an opaque material, but is preferably composed of an opaque material. By comprising an opaque material, a liquid material with insufficient light resistance can be stably stored over a long period of time without alteration or the like.

(Experimental example 1)
(1) Experimental Cap FIG. 20 is a schematic perspective view showing a schematic configuration of the experimental caps 60A to 60D. The experimental cap 60A in (a) is provided with a band-like color region 61 (area 1620 mm 2) in an annular shape at the upper end of the inner side surface 22 of the side wall 12 and in the vicinity thereof. The experimental cap 60 </ b> B in (b) is provided with a belt-like colored region 62 (area 563 mm <2>) in an annular shape at a substantially central portion in the vertical direction on the inner side surface 22 of the side wall 12. The experimental cap 60C in (c) has a ring-shaped colored region 63 (area 387 mm 2) provided in an annular shape at the lower end of the inner side surface 22 of the side wall 12 and in the vicinity thereof. The experimental caps 60A to 60C are comparative samples. The cap 60D for experiment of (d) is provided with a color region 64 (area 332 mm 2) on the bottom surface 21 surrounded by the seal ring 15, and is a sample of the cap of the present invention. The color of the belt-like colored areas 61, 62, 63 and the color area 64 is the same color (green). Further, apart from the experimental caps 60A to 60D, the following experiment was also conducted on a blank white cap (no color region and no strip-shaped colored region) that was not colored as a whole and had the same dimensions as the experimental caps 60A to 60D. .

(2) Measurement of liquid surface chromaticity In the experimental cabs 60A to 60D and the inner side surface 22 of the blank white cap, a rectangular region surrounded by black circles shown in FIG. A color photograph of the region 66 was taken with water poured until the 66 was immersed, and an average color of the region 66 was obtained from the obtained color photograph using an image processing software (trade name: Adobe Photoshop, manufactured by Adobe). * A * b value was converted into a numerical value, L-a-b three-dimensional mapping was performed, and the liquid surface chromaticity was determined.

(3) Side chromaticity For the experimental cabs 60A to 60D and the blank white cap, water was poured until the area 66 was immersed, and the white area was surrounded by a white circle from the end of the area 66 to the upper end of the inner side surface 22. A color photograph of the rectangular area 65 (FIG. 20D) is taken, and the average color of the area 65 is digitized from the obtained color photograph by the L * a * b value in the same manner as in the above (2). -A-b Three-dimensional mapping was made and the side chromaticity was set.

(4) Correction of liquid surface chromaticity From the liquid surface chromaticity and side chromaticity obtained above, the distance (difference) between the liquid surface chromaticity and the side surface chromaticity is obtained to correct the liquid surface chromaticity, The obtained correction value (distance) was defined as the true coloring degree of the liquid level in each cap. It shows that the greater the value of the true coloring degree, the higher the degree of appearance of coloring. The results are shown in FIG.

  From FIG. 21, the cap 60D provided with the color area 64 having the smallest area on the bottom (bottom surface 21) is the upper part of the inner side surface 22 (upper end and its vicinity), the middle part of the inner side surface 22 (substantially the central part in the downward direction) Compared with the caps 60A to 60C in which the belt-like colored regions 61 to 63 are provided at the lower part (lower end and the vicinity thereof) of the inner side surface 22, the color of the liquid level, which is the distance (difference) between the liquid level chromaticity and the side chromaticity The degree has increased. From this result, it can be seen that the degree of coloration of the liquid surface is more greatly affected by the position of the color area or the band-like color area than the area of the color area or the belt-like color area. More specifically, by providing the color region on the bottom surface 21 rather than the inner side surface 22, the degree to which the liquid surface appears colored is significantly increased.

(Experimental example 2)
The distance (difference) between the liquid surface chromaticity and the side chromaticity was determined in the same manner as in Experimental Example 1 for the same white cap as in Experimental Example 1, and the caps 1, 1A, 1B, 1D, 2A, and 3A. The color area of each cap is green. The results are shown in FIG. From FIG. 22, the caps 1, 1A, 1B, 1D, 2A, and 3A of the present invention have high liquid surface coloring, and particularly the cap 1 and the caps 1A, 1D that are variations thereof have high liquid surface coloring. It can be seen that the liquid surface coloring degree of 1A is remarkably high.

(Experimental example 3)
About the same white cap as Experimental example 1, and said cap 1A and 3A, it carried out similarly to Experimental example 1, and calculated | required the distance (difference) of liquid level chromaticity and side surface chromaticity. The color area of each cap is red. The results are shown in FIG. From FIG. 23, it can be seen that the caps 1A and 3A of the present invention have high liquid surface coloration, and in particular, the liquid surface coloration of the cap 1A which is a modified example of the cap 1 is remarkably high. From this result, it can be seen that not only green but also red is very effective as the color of the color region.
