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 main body filled with a transparent liquid material and that can measure the transparent liquid material almost accurately and easily, and the cap. It relates to a container provided with.

  Most liquid products such as liquid cosmetics such as mouthwashes, liquid quasi-drugs, liquid pharmaceuticals such as gargles and syrups, and laundry, household, residential, and furniture detergents are made of resin materials. It is distributed in the market in the form filled in bottle-shaped containers. 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 it remove | eliminates a cap from the opening | mouth part of a container main body, it is comprised so that a liquid substance may be measured by pouring a liquid substance into the inside in an inverted shape.

  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 may be 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 is 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 as a through hole is provided on a side wall, and an outer cylinder that is provided in contact with an outer wall 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 wall 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 wall surface of the cap, the visibility of the liquid surface of the transparent liquid material is not improved so much.

  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 wall 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.

  On the other hand, as a method of using the lenticular lens, for example, a case having a transparent front wall, filled with liquid inside, and a stripe-shaped pattern formed on the surface, and floating in the liquid in the case There has been proposed a toy comprising a body and a lenticular lens affixed to the transparent front wall of the case and configured to enjoy watching a change in the pattern of the swimming body through the lenticular lens (Patent Document 3).

  Patent Literature 1 and Patent Literature 2 only disclose a measuring cap that attempts to improve the visibility of the liquid level by combining the internal structure of the cap and the coloring of the inner wall surface of the cap. Further, Patent Document 3 only discloses a toy that enjoys the fact that the stripe pattern on the surface of the suspended object appears to be changed by the lenticular lens, and discloses a technical idea that uses the lenticular lens as a mark for measuring the amount of liquid. Not what you want. As described above, the lenticular lens is conventionally well-known for enjoying the change in the picture depending on the viewing angle. For example, the lenticular lens has been used for a toy, but there is no example of using it as a mark for measuring liquid.

  The outer wall surface 22 of the side wall 12 has a plurality of bottoms extending substantially in parallel along a height direction from the bottom surface 20 of the cap 1 toward the opening 10 (hereinafter sometimes simply referred to as “the height direction of the cap 1”). Shallow and narrow grooves 22a are densely formed in the circumferential direction to facilitate rotation of the cap 1 when the cap 1 is attached to and detached from the mouth. Without being limited to the present embodiment, a plurality of grooves or protrusions extending in the circumferential direction may be formed on the outer wall surface 22, and the outer wall surface 22 may be a smooth surface. On the other hand, the weighing display unit 13 is provided on the inner wall surface 23 of the side wall 12. The color of the area other than the measurement display unit 13 on the inner wall surface 23 is not particularly limited as long as it is a color that can clearly see the image change above and below the liquid level in the measurement display unit 13, and may be the same color or two or more different colors. However, it is configured in the same color in the present embodiment from the viewpoint of more reliably viewing the image change in the weighing display unit 13 and improving the visibility of the liquid surface and thus the weighing property. Although this color is not specifically limited, For example, it is preferable that it is almost white.

  In the present specification, almost white means not only pure white, but also pale yellowish white, lightly skinned white, lightly blackish white, lightly reddish white, lightly greenish Also included are whites that are lightly mixed with other colors, such as white and light blue. In other words, generally white is a color having a whiteness higher than that of at least newspaper (whiteness 55), preferably a color exceeding whiteness 60, and more preferably a color exceeding whiteness 70.

  In the present embodiment, the boundary region between the bottom wall 11 and the side wall 12 is configured to be a gently curved surface both inside and outside, but is not limited to this. For example, the bottom wall 11 and the side wall 12 are orthogonal to each other. You may comprise.

  The weighing display unit 13 includes a lenticular image unit in which images of two different forms are arranged in an interlaced manner along the height direction of the cap 1, and a lenticular lens formed on the surface of the lenticular image unit. And a lenticular portion 16 having a lens portion. The lenticular portion 16 has an opening end portion 10a on the inner wall surface 23 through an intermittent width of two protruding strips 14a adjacent to each other in the circumferential direction at the protruding portion 14 from a position substantially the same as the upper end of the seal ring 15. It is arranged to reach the vicinity.

  Next, the lenticular portion 16 will be described in more detail with reference to FIG. 2A and 2B are diagrams schematically showing an enlarged configuration of the lenticular portion 16, where FIG. 2A is a side view and FIG. 2B is a perspective view. The lenticular portion 16 shown in FIG. 2 includes a lenticular image portion 30 and a lenticular lens portion 32 formed on the surface of the lenticular image portion 30.

  The lenticular image portion 30 includes a plurality of band-shaped unit images 31 that are repeatedly arranged in the length direction of the lenticular portion 16, and each unit image 31 has three different band shapes that extend substantially parallel to the width direction of the lenticular portion 16. The partial images 31a, 31b, and 31c are arranged in an interlaced manner along the length direction (or height direction) of the lenticular portion 16. The partial images 31 a, 31 b, and 31 c are substantially the same size in the width direction of the lenticular portion 16. By appropriately selecting the number, color, width, extending direction, and the like of the partial images in the unit image 31, it is possible to express different colors, different patterns, presence / absence of patterns, combinations thereof, and the like. The above images can be displayed. The number of images displayed by the lenticular image portion 30 is not particularly limited as long as it is 2 or more, but is preferably 2 or 3 from the viewpoint of the visibility of image change when a liquid material is poured into the cap 1. In the present specification, this number of images may be referred to as an imposition number.

  In the present embodiment, the widths of the partial images 31a, 31b, and 31c are substantially the same, but can be changed as appropriate in order to obtain a desired image change. In the present embodiment, the unit image 31 and the partial images 31a, 31b, and 31c are provided so as to extend in a direction perpendicular to the length direction (or height direction) of the lenticular unit 16, but the vertical direction is vertical. You may incline not only a direction but diagonally.

  The lenticular lens unit 32 includes a plurality of lenticular lenses 33 that are provided on the surface of the lenticular image unit 30 and that have a convex shape (preferably in the shape of a section) extending in the width direction of the lenticular unit 16. More specifically, the lenticular lens unit 32 is formed by arranging a plurality of lenticular lenses 33 in the length direction of the lenticular unit 16 on the surface of the lenticular image unit 30, and one lenticular lens 33 is one unit. The image 31 is configured to be covered.

  The pitch (width) of the lenticular lens 33 is not particularly limited. For example, the pitch can be appropriately selected from the range of 30 Lpi to 200 Lpi (Line per inch), but the viewpoint of widening the viewing angle range where the image change of the lenticular portion 16 can be clearly visually recognized. Therefore, it is preferably in the range of 60 Lpi to 125 Lpi, more preferably 60 Lpi to 120 Lpi, and still more preferably 70 Lpi to 100 Lpi. When the pitch of the lenticular lens 33 is within the above range (especially by setting the pitch to be in the range of 60 Lpi to 120 Lpi and the number of impositions is 2), the viewing angle (gaze angle) with respect to the lenticular portion 16 is 5 °. The image change of the lenticular portion 16 can be clearly visually recognized in a very wide range of ˜65 °. As a result, even if the position where the cap 1 is held or the angle at which the cap 1 is viewed varies depending on the user, the image change can be easily visually recognized.

  Further, the thickness (maximum thickness) of the lenticular lens 33 can be appropriately selected from a range of about 0.1 to 2 mm, but is preferably 0.2 mm to 1.5 mm, more preferably 0, from the viewpoint of easily recognizing image changes. .3 mm to 0.5 mm. Here, the maximum thickness of the lenticular lens 33 is the thickness of the central portion of the lenticular lens 33 in the width direction.

  The lenticular section 16 has been conventionally well known as a lenticular sheet, and is configured to enjoy image changes by adjusting the angle of the line of sight by appropriately tilting the lenticular section itself vertically and horizontally. On the other hand, in the present invention, the refractive index under the liquid level (liquid layer) filled with the liquid substance and the refractive index of the air above the liquid level (air layer) without greatly changing the line-of-sight angle. Is used to change the image existing in the liquid layer of the lenticular portion 16 and / or the image existing in the air layer, and using this change as a part of the measurement mark, Visibility is improved and meterability is improved.

  As shown in FIG. 1A, in the lenticular portion 16 of the present embodiment, in a state where the liquid material 17 is not poured, a substantially rectangular thin colored region and a substantially rectangular white region are alternately arranged in a grid pattern vertically and horizontally. And a coloring numeral “20” arranged in the white area located in the center of the width direction of the predetermined area relatively in the length direction, and the color extending in the width direction from both ends of the white area in the width direction A measurement mark having a measurement line, a colored numeral “10” arranged in a white area located in the center of the width direction of the predetermined area relatively in the length direction, and the width direction of the white area Two weighing marks, that is, another weighing mark having a colored weighing line extending in the width direction in the colored region from both ends, are drawn. When the liquid material 17 is poured into the cap 1, as shown in FIG. 1 (b), the white area disappears and the measuring line changes to white, so that the liquid surface 17a (more specifically, the liquid surface). The position of the boundary 17a and the inner wall surface 23 is easy to visually recognize, and weighing is facilitated.

  Note that the angle at which all users view the cap 1 is not uniform, and the angle at which the user views the cap 1 is generally different depending on the user. Therefore, even when many users look at the cap 1 at an angle that causes an image change from FIG. 1A to FIG. 1B, some users are different from the image change described above. There is a case where the cap 1 is viewed at an angle at which an image change, that is, an image change from FIG. 1B to FIG. 1A occurs. However, in any image change, the visible images of the liquid layer below the liquid level and the air layer above the liquid level are clearly different, so the visibility of the liquid level and liquid level movement is remarkably improved and almost accurate. It is the same in that accurate weighing becomes possible. As in the present invention, in all cases where weighing is performed using the lenticular portion 16 using a lenticular sheet, any one of the above image changes can be visually recognized by the user and used for weighing.

  In the present embodiment, the lenticular portion 16 has an intermittent width between two protruding strips 14a adjacent to each other in the circumferential direction of the protruding portion 14 from the substantially same height position as the upper end of the seal ring 15 on the inner wall surface 23. A recess 18 corresponding to the three-dimensional shape of the lenticular portion 16 is formed in a region reaching the vicinity of the opening end portion 10 a through and passing through the recess 18. For fixing the lenticular portion 16 to the concave portion 18, for example, means such as adhesion, fitting, and heat fusion are used. Note that the lower end of the lenticular portion 16 may extend to the vicinity of the bottom surface 20, which may further improve the visibility of image changes with the liquid level as a boundary. Further, it is preferable that the surface of the lenticular portion 16 and the inner wall surface 23 are substantially flush with each other because the sealing property and airtightness when the cap 1 is attached to the mouth of the container are increased.

  FIG. 3 is a plan view showing a specific example of an image change of the lenticular portion 16 caused by pouring a liquid material into the cap 1. In FIG. 3, the upper drawing in the vertical direction of the paper shows an image when the liquid material is not poured (hereinafter referred to as “upper image”), and the lower drawing is when the liquid material is poured to the upper end.

Two measuring marks having a measuring line extending in the width direction are drawn. On the other hand, in the lower image, the measurement mark remains as it is, but a bottle filled with a liquid material is drawn instead of three toothbrushes. As the amount of liquid poured into the cap 1 increases, the image change from the three toothbrushes to the bottle rises toward the opening 10, making it easier to visually recognize the position of the liquid level, and a measurement mark Makes weighing easier.

  In the upper image of FIG. 3B, at a predetermined position in the length direction, a white rectangular frame, colored numerals arranged in the frame, a measuring line extending in the width direction from both ends of the frame, And two lines extending substantially parallel to the length direction at a predetermined interval. On the other hand, the lower image has the same measurement mark as the upper image except that the measurement line is colored, and a plurality of lines extending in the width direction with a predetermined interval. As the amount of liquid poured into the cap 1 increases, the line extending in the length direction disappears and the line extending in the width direction appears, and the measurement line is colored, so that the position of the liquid surface is visually recognized. It becomes easy and the measurement by the measurement mark becomes easy.

  In the upper image of FIG. 3 (c), a rectangular red region and a rectangular white region are alternately arranged in a grid pattern in the vertical and horizontal directions, and the white color arranged in the central red region in the width direction at a predetermined position in the length direction. Two measuring marks are drawn having numbers and colored measuring lines extending in the width direction in the white region from both ends of the red region where the white numbers are arranged. The lower image has the same measurement mark as the upper image except that a white image is arranged at a position corresponding to the red area of the upper image, a blue area is arranged at a position corresponding to the white area, and numbers are colored. It is drawn. When liquid material is poured into the measuring cap 1, the red area disappears and the blue area appears, making it easier to visually recognize the position of the liquid level. Becomes easier.

In the lower image, square red regions and square white regions are alternately arranged in a grid pattern in the vertical and horizontal directions, and the same measurement marks as those in the upper image are drawn except that the measurement lines are colored. As the liquid is poured into the cap 1, the blue color disappears and a grid pattern of red and white areas appears, and the measurement lines are colored to make it easier to see the liquid level and easily measure with the measurement mark. become.

  FIG. 4 is a plan view showing another specific example of the image change of the lenticular portion 16 caused by pouring the liquid material into the cap 1. In FIG. 4, the upper drawing in the vertical direction of the paper shows an image when the liquid material is not poured (hereinafter referred to as “upper image”), and the lower drawing is when the liquid material is poured to the upper end. (Hereinafter referred to as “lower image”). Note that the image change shown in FIG. 4 is a typical example. When water is poured, an image change from the lower image to the upper image may be visually recognized depending on the user. In FIG. 4, colors are not shown.

  In the upper image of FIG. 4A, a rectangular white region is arranged in the red background screen at the center in the width direction at a predetermined position in the length direction. Two weighing marks having a colored numeral located in the white area and white lines extending in the width direction from both ends of the white area are drawn. The lower image has the same measurement mark as the upper image except that the red background screen is replaced by the blue background screen. As the liquid material is poured into the cap 1, the color of the screen changes from red to blue, so that the liquid level can be easily seen and the measurement with the measurement mark becomes easy.

  In the upper image of FIG. 4B, an overall outline of the cloud, a yacht of a boat is drawn, and a plurality of weighing marks having a weighing line extending in the width direction at a predetermined position in the length direction are drawn. ing. In addition, on the upper measurement line, the shadow of an airplane flying in the sky is overlaid. The lower image shows a rainbow that extends in a partial arc from the lower part in the length direction at the left end to the upper part in the length direction at the right end, a yacht of multiple boats floating on the water surface at the lower part in the length direction, and between the rainbow and the yachts. A partially expanding cloud and the same measurement line as the upper image are drawn. As the liquid material is poured into the cap 1, yachts of a plurality of boats appear on the screen, and a rainbow appears, so that it is easy to visually recognize the rise in the liquid level, and measurement with a measurement mark becomes easy.

  In the upper image of FIG. 4 (c), approximately rhombus red areas and approximately rhombus white areas are arranged in a grid pattern alternately in the vertical and horizontal directions, and arranged in the white area at the center in the width direction at a predetermined position in the length direction. A measuring mark having a colored number and a measuring line extending in the width direction from both ends in the width direction of the white region where the colored number is arranged is drawn. In the lower image, the same image as the upper image is drawn except that the approximately rhombus red region is replaced by the approximately rhombus blue region. As the liquid material is poured into the cap 1, the red area disappears and the blue area appears, so that the liquid level can be easily seen and the measurement with the measurement mark becomes easy.

  In the upper image of FIG. 4 (d), a plurality of triangular red areas extending from the lower end to the upper end in the length direction and having an acute angle are arranged side by side in the width direction, and the width at a predetermined position in the length direction. Two measuring marks having a colored numeral arranged between two red regions at the center in the direction and a measuring line extending in the width direction from the vicinity of both ends of the colored numeral in the width direction are drawn. In the lower image, the same image as the upper image is drawn except that the red region is replaced with the blue region. As the liquid material is poured into the cap 1, the red area disappears and the blue area appears, so that the liquid level can be easily seen and the measurement with the measurement mark becomes easy. Moreover, in this embodiment, since the movement of a liquid level can be confirmed also when the width | variety of the blue area which appears gradually becomes narrow, the visibility of a liquid level further improves.

  In addition, in the lenticular unit 16, the liquid level can be visually recognized if at least different images are displayed with the liquid level as a boundary. Therefore, the upper and lower images do not have to be the same. Further, when a liquid material is poured into the cap 1, due to the characteristics of the lenticular portion 16, an image change occurs above and below the liquid level, and only the area close to the bottom surface 20 may return to the original image. Even in such a case, if the change in the image above and below the liquid level can be confirmed, it can be used without any particular problem. However, it is preferable that the entire range above and below the liquid surface is the same image.

Hereinafter, the description will return to the entire cap 1 shown in FIG.
The ridge portion 14 includes a plurality of ridge pieces 14a that are intermittently provided in a spiral manner in the circumferential direction of the inner wall surface 23, avoiding the weighing display portion 13, and the plurality of ridge pieces 14a are formed on the container body. The cap 1 is attached to the mouth of the container body by screwing with a screw structure provided on the outer periphery of the mouth.

  The seal ring 15 rises in an annular shape from the bottom surface 20 around the center core (not shown) of the cap 1 toward the opening 10, and when the cap 1 is attached to the mouth of the container body, the periphery of the mouth This seals the container to prevent liquid leakage, especially when the container body is tilted.

,
The size of the cap 1 is appropriately selected according to the filling amount of the liquid material set in the container body, the dimensions of the container body and the mouth portion, and the like, but is not limited. The height is about 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 liquid substance of about 10 to 40 ml can be easily weighed. In addition, you may comprise so that a dimension can be enlarged and a larger amount of liquid substances can be measured.

  FIG. 5 is a perspective view schematically showing the configuration of the cap 2 according to the second embodiment of the present invention. In FIG. 5, the same reference numerals as those in FIG. In the cap 2, two weighing display portions 13 facing each other through the seal ring 15 are provided on the inner wall surface 23 of the side wall 12 at substantially equal intervals in the circumferential direction, and each weighing display portion 13 is configured by a lenticular portion 16. It is characterized by being. With this configuration, when the user picks up the cap 2, the angle of the line of sight with respect to the weighing display unit 13 can be easily adjusted, and the usability of the cap 2 is improved.

  The two lenticular portions 16 may cause the same image change by pouring liquid material, or may cause different image changes. The number of lenticular parts 16 is not limited to 1 or 2, and may be 3 or more. When three or more lenticular portions 16 are provided, they are preferably arranged at substantially equal intervals in the circumferential direction. By providing three or more lenticular portions 16 at substantially equal intervals in the circumferential direction, when the cap 2 is picked up, any one of the lenticular portions 16 enters the field of view. , There is no need to rotate the cap 2.

  FIG. 6 is a perspective view schematically showing the configuration of the cap 3 according to the third embodiment of the present invention. (A) shows a state where no liquid material is poured, and (b) shows a state where a liquid material is poured. In FIG. 6, the same reference numerals as those in FIG. The cap 3 includes a stepped portion 24 provided with a predetermined width at a predetermined position in the circumferential direction of the side wall 12, and a lenticular portion 16 disposed along the stepped portion 24 on the inner wall surface 23 side of the stepped portion 24. The measurement display unit 19 is configured, and the other configuration is the same as that of the cap 1.

  The step portion 24 has substantially the same width as the intermittent width of the two protruding strips 14 a provided so as to be separated from each other in the circumferential direction on the inner wall surface 23, and is substantially the same as the upper end of the seal ring 15 on the side wall 12. It is provided so as to extend from the same height position to the opening end 10a, and is inclined at a predetermined angle with respect to the direction in which the central axis of the cap 3 extends. Further, the step portion 24 becomes a convex portion 25 on the outer wall surface 22 side of the side wall 12 and becomes a concave portion 26 on the inner wall surface 23 side. Therefore, the surface of the convex portion 25 and the bottom surface of the concave portion 26 are also inclined at a predetermined angle with respect to the direction in which the central axis of the cap 3 extends. The inclination angle of the stepped portion 24 is not particularly limited, but is preferably 20 ° or less, more preferably 10 to 20 °. The convex portion 25 also has a function of assisting the rotation of the cap 3 when the cap 3 is attached to and detached from the mouth portion of the container body.

  In the present embodiment, both the convex portion 25 and the concave portion 26 are configured to incline substantially in parallel. However, the stepped portion 24 is made thicker at the lower end side region and becomes thinner toward the upper side. The outer wall surface 22 of the side wall 12 is formed in a tapered shape, is substantially flush with the outer wall surface 22 or slightly protrudes from the outer wall surface 22, and only the bottom surface of the recess 26 has the central axis of the cap 3. You may comprise so that it may incline with respect to the extending direction.

  The lenticular portion 16 is disposed on the bottom surface of the concave portion 26 on the inner wall surface 23 side of the stepped portion 24 and constitutes a weighing display portion 19. The lenticular portion 16 is fixed to the bottom surface by means such as adhesion, fitting, and heat fusion. The lenticular portion 16 disposed on the bottom surface has the same inclination angle of 20 ° or less as the step portion 24. That is, in the measurement display part 19 of this embodiment, the lenticular part 16 inclines to the upper side which is the opening part 10 side.

  By comprising in this way, the image change which used the liquid level in the measurement display part 19 (lenticular part 16) as a boundary can be visually recognized still more clearly. In particular, in the lenticular portion 16 on the side close to the bottom surface 20 of the measuring cap 3, as the height of the liquid surface in the cap 3 increases, a phenomenon may occur in which the original image before changing appears depending on the angle of the line of sight. . However, by arranging the lenticular portion 16 so as to be inclined as in this embodiment, the occurrence of such a phenomenon is reduced as much as possible, and the visibility of image changes with the liquid level as a boundary is remarkably improved. Can do.

  In the present embodiment, it is preferable that the step portion 24 and the lenticular portion 16 are inclined at a certain angle, but the present invention is not limited to this, and for example, the step portion 24 may be inclined in a curved shape (for example, the lower side is inclined more greatly). Etc.), the inclination angle may be changed once or a plurality of times in the middle of the opening end 10a.

  FIG. 7 is a perspective view schematically showing the configuration of the cap 4 according to the fourth embodiment of the present invention. The cap 4 is characterized in that the step portion 24 and the weighing display portion 19 in the cap 3 are provided at four locations on the side wall 12, and the other configuration is the same as that of the cap 3. The four step portions 24 and the weighing display portions 19 are provided at substantially equal intervals in the circumferential direction of the cap 4, and two each are opposed to each other. If comprised in this way, the image change in the upper and lower sides of the liquid level becomes clearer, and the meterability is further improved. When the cap 4 is removed from the mouth portion, how to hold the cap 4 and the cap 4 Even if the angle of the line of sight is not changed, the entire weighing display unit 19 enters the field of view, so that the handleability is remarkably improved. That is, the cap 4 has the preferable characteristics of the caps 2 and 3 together.

  FIG. 8 is a perspective view schematically showing the configuration of the cap 5 according to the fifth embodiment of the present invention. In FIG. 8, the same reference numerals are given to the common parts with FIG. The weighing cap 5 is characterized in that the weighing display portion 13a is composed of a lenticular portion 16a. The lenticular portion 16a is characterized by having two regions having different widths in the direction from the bottom surface 20 toward the opening end portion 10a. More specifically, in the lenticular portion 16a, the region above the ridge portion 14 composed of a plurality of ridge pieces 14a (the height position where the ridge portion 14 does not exist) includes the ridge portion 14 as well. It is wider than the area below it (that is, the area where the ridges 14 are present).

  According to the cap 5, since the display area of the weighing display portion 13a can be increased without increasing the intermittent width of the adjacent protruding strips 14a, the function of sealing the container mouth portion of the cap 5 and the liquid material can be increased. The liquid level at the time of pouring can be clearly recognized, and the function of measuring an almost accurate liquid amount can be made compatible at a high level. In addition, when the intermittent width of the protrusion strip 14a is increased, it becomes difficult to perform the hooking between the protrusion strip 14a of the cap 5 and the thread formed on the mouth portion of the container body as intended by the design. May not be properly attached to the bottle, resulting in a problem of insufficient sealing.

A container according to another embodiment of the present invention includes a container body for filling a liquid material having a mouth part for pouring a transparent liquid material into the cap, and a cap detachably attached to the mouth part, The cap is the above-described measuring cap of the present invention.

  The liquid material filled in the container of the present invention is not particularly limited as long as it is transparent, but a transparent liquid material having a critical micelle concentration (CMC) higher than that of water is preferable, and the surfactant concentration is 10% by weight or less. A transparent liquid material having an alcohol concentration of 20% by weight or less is more preferable. The surfactant concentration is more preferably 0.01 to 10% by weight, still more preferably 0.01 to 5% by weight. The alcohol concentration is more preferably 0.1 to 20% by weight, and still more preferably 1 to 20% by weight. The lenticular portion in the cap of the present invention is a surface in which a plurality of convex (preferably kamaboko) lenticular lenses are arranged side by side, and there are many grooves between the lenticular lenses. Under the influence of surface tension, disturbances such as steps are likely to occur at the boundary between the lenticular lens and the liquid surface.

  FIG. 9 is a schematic diagram showing a boundary state between the liquid level and the lenticular portion 16 surface when water is poured into the cap 1. Since water has a relatively high surface tension, when the surface of the water and the surface of the lenticular portion 16 come into contact with each other, the level of the water tends to be disturbed by forming a step or the like, making accurate measurement difficult. There is a case. When water is poured into the cap 1, in FIG. 9A, a step is generated on the liquid surface at one end, and in FIG. 9B, the step is increased and moves toward the other end. In FIG. 9 (c), after the step becomes large near the other end, the step in the liquid level disappears in FIG. 9 (d), but it is difficult to coincide with the horizontal line. Therefore, if water is to be accurately measured, it takes time until the liquid level is settled, and accurate measurement cannot be performed in a short time.

  On the other hand, a transparent liquid material having a higher critical micelle concentration than water has less disturbance of the liquid surface, and the liquid surface immediately rises in line with the horizontal line, so accurate measurement can be performed in a short time. it can. In order to increase the critical micelle concentration of the transparent liquid material, for example, a method of adding an additive such as a surfactant or alcohol to the transparent liquid material can be mentioned. Accordingly, by setting the surfactant concentration to 10% by weight or less and / or the alcohol concentration to 20% by weight or less, the critical micelle concentration of the transparent liquid is further increased and the surface tension is further decreased. It is possible to more easily carry out the measurement.

  The transparent liquid material that can be filled in the container of the present invention is not particularly limited. For example, liquid cosmetics such as mouthwash, mouthwash, liquid quasi-drugs, liquid pharmaceuticals such as syrups, liquid agricultural chemicals, and laundry Examples include household detergents, furniture and building detergents, and liquid cosmetics, liquid quasi-drugs, liquid pharmaceuticals, and the like are preferable. Many of these contain a surfactant and alcohol, and have a low surface tension. Therefore, they are suitable for measurement using the cab of the present invention having a lenticular portion as a measurement mark.

  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 transparent liquid material with insufficient light resistance can be stably stored over a long period of time without alteration or the like.
