Description

  The present invention relates to a measuring cap and a container.

  In the case of a container for storing a liquid detergent such as a clothing liquid detergent or a bleaching agent, a measuring cap provided with a measuring function is used in order to use an appropriate amount of the contents (liquid) of the container. This type of measuring cap is provided with a measuring display section on which symbols such as scales, characters, and the like are displayed in order to confirm the amount of content to be dispensed.

  As a method of providing a character / graphic on the measuring cap, for example, the character / graphic is raised in a relief shape at the time of injection molding, or the character / graphic is printed by a hot stamp. However, when it is molded into a relief shape, the visibility is low, and in the case of a hot stamp, it is colored so that the visibility is higher than when it is molded into a relief shape. In addition to the problem of disappearance (if the content contains an organic solvent or a surfactant, characters and figures may be peeled off or melted), there is a problem that the manufacturing cost increases.

Therefore, in Patent Document 1, a character / figure is formed on the outer surface or inner surface of the measuring cap by using a CO ₂ laser or a YAG laser and irradiating a laser beam by a scanning method to provide a burn mark on the resin. Technology is disclosed.

Utility Model Registration No. 31141949

And an inner plug 6 attached to the mouth 3.

  The container body 2 is integrally formed by, for example, blow molding using an olefin-based synthetic resin such as polyethylene. The container body 2 contains, for example, liquid substances such as liquid detergents, liquid bleaches, liquid softeners, and solvents, and granular substances such as granular detergents, granular bleaches, and granular seasonings as contents. It has a space 2a. The mouth portion 3 of the container body 2 is formed in a cylindrical shape centering on a central axis C extending in the vertical direction. The mouth 3 is opened with the accommodation space 2a facing upward. A male screw portion 3 a is formed around the central axis C on the outer periphery of the mouth portion 3.

  In the following description, a direction along the central axis C is appropriately referred to as a central axis direction, a direction orthogonal to the central axis C is referred to as a radial direction, and a direction around an axis centering on the central axis C is appropriately referred to as a circumferential direction. Further, the opening side of the mouth part 3 in the central axis direction will be referred to as the upper side, and the bottle inner side of the mouth part 3 will be referred to as the lower side as appropriate.

  For example, the inner plug 6 is formed by injection molding using an olefin-based synthetic resin such as polypropylene. The inner plug 6 extends along the central axis C and is fitted to the inner peripheral surface 3 b of the mouth portion 3. The upper end of the mouth portion 3 extends radially outward from the upper end of the tubular portion 31.

  The nozzle 34 extends upward from the bottom wall portion 33. The nozzle 34 is formed in a bowl shape having a U-shaped cross-sectional shape. The inside of the nozzle 34 having a U-shaped cross section communicates with the storage space 2 a of the container body 2 through a communication portion 36 formed in the bottom wall portion 33.

  The measuring cap 4 is formed by injection molding using an olefin synthetic resin such as polypropylene, for example. The measuring cap 4 enters the inside of the cylindrical part 31 and is arranged at a position surrounding the periphery of the nozzle 34 and has a covered cylindrical measuring cylinder part 41 having a lid part 44 at the upper end, and the measuring cylinder part 41 in the direction of the central axis C. The flange portion 43 protrudes radially outward from the middle, and the cylindrical screw portion 42 extends downward from the radially outer edge of the flange portion 43. The lid 44 of the measuring cylinder 41 is orthogonal to the central axis C, and can be stably placed with the opening of the measuring cylinder 41 facing upward. The measuring cylinder part 41 and the screwing part 42 are arranged coaxially with the central axis C as the center.

  The screwing portion 42 is disposed at an interval on the outer side in the radial direction of the measuring tube portion 41. On the inner peripheral surface of the screwing portion 42, a female screw portion 42a that is screwed with the male screw portion 3a of the mouth portion 3 is formed. The measuring cap 4 is configured such that when the female threaded portion 42a of the threaded portion 42 is screwed into the male threaded portion 3a of the mouth portion 3 and attached to the container body 2, the lower side of the flange portion 43 is connected to the flange portion 32 of the inner plug 6. The opening part of the mouth part 3 is closed by pressing the upper end part of the mouth part 3 through.

FIG. 2 is an external perspective view of the measuring cap 4 in which the lid portion 44 is disposed on the lower side.
The measuring cap 4 is configured to be transparent or translucent, and the contents such as the detergent injected into the measuring tube portion 41 with the lower end (opening portion) of the measuring tube portion 41 facing upward, and the measuring tube portion The relative position with respect to the weighing display unit 50 that is arranged on the outer circumferential surface (circumferential surface) 41a of 41 and displays information related to weighing of contents can be visually recognized from the outside.

  The weighing display unit 50 according to the present embodiment includes a weighing display unit 50A indicating that the amount of contents injected into the measuring tube unit 41 is 10 cc, and the amount of contents injected into the measuring tube unit 41 is 20 cc. And a weighing display unit 50B. The weighing display units 50A and 50B include at least one of a character such as a number and a figure such as a line as a symbol indicating information related to the weighing of the contents.

  Specifically, the weighing display unit 50A is formed in a linear shape in the circumferential direction centering on the central axis C, and a symbol 51 indicating a liquid level when 10 cc of contents is injected into the weighing tube unit 41; A symbol “1” indicating that the symbol 51 is 10 cc, a symbol 52 indicated by “0”, and an arrow-shaped symbol 53 that highlights the position of the symbol 51 are provided. The weighing display portion 50B is formed in a linear shape in the circumferential direction centering on the central axis C, and a symbol 54 indicating the liquid level when 20 cc contents are injected into the weighing tube portion 41, and the symbol 54 is 20 cc. There are a symbol 55 indicated by the numbers “2” and “0” indicating the presence, and a symbol 56 indicated by an arrow-shaped figure that highlights the position of the symbol 54.

  FIG. 3A is a partial cross-sectional view of the portion of the measurement cylinder portion 41 where the symbols 51 to 56 are arranged, cut along a cross section orthogonal to the central axis C. FIG. FIG. 3B is an enlarged partial cross-sectional view of FIG. In FIG. 3, the symbols 51 to 56 will be described as the symbol 60 as a representative.

  The symbol 60 has a three-dimensional part 61 formed on the outer peripheral surface 41 a of the measuring cylinder part 41 and a contour part 62 arranged along the contour of the three-dimensional part 61. In other words, the three-dimensional part 61 is arranged in a region surrounded by the contour part 62. The three-dimensional part 61 includes a convex part formed on the outer peripheral surface 41 a in the shape of the symbol 60. As an example, the three-dimensional part 61 is formed by injection molding using a mold having a recess provided in accordance with the shape of the symbol 60 and molding the outer peripheral surface 41a. The convex amount of the three-dimensional part 61 is, for example, 0.01 to 0.3 mm.

  The contour portion 62 is colored by irradiating the outer peripheral surface 41 a with the laser light 20 as energy light along the contour of the three-dimensional portion 61. Examples of the device that irradiates the laser beam 20 include a carbonic acid laser device, a YAG laser device, and a YVO4 laser device. The YAG laser device uses yttrium / aluminum / garnet as a crystal medium. The YVO4 laser device uses yttrium / vanadium tetroxide as a crystal medium.

  The formation of the contour portion 62 by the irradiation of the laser beam 20 is performed by continuously irradiating the laser beam 20 shaped into a dot shape of several tens of μm (for example, 40 μm) by the scanning method along the contour of the three-dimensional portion 61. Done. The outer peripheral surface 41a irradiated with the laser beam 20 is colored from carbonization, foaming, evaporation, etc. (details will be described later).

  Returning to FIG. 2, the outer peripheral surface 42 a of the screwed portion 42 is arranged with the smoothing unit 70 arranged in a range where the weighing display units 50 </ b> A and 50 </ b> B are arranged in the circumferential direction and the weighing display units 50 </ b> A and 50 </ b> B in the circumferential direction. And a knurled portion 71 arranged in a range not formed. The knurled portion 71 has a plurality of protrusions that are arranged at regular intervals in the circumferential direction and extend substantially parallel to the central axis C. Since the knurled part 71 is arranged in a range where the weighing display parts 50A and 50B are not arranged, the grasping property to the screwing part 42 is improved, and the contents injected into the measuring cylinder part 41 are visible. It can suppress that it falls by the knurled part 71. FIG.

  Further, the outer peripheral surface 42 a of the screwed portion 42 has an indicator portion 72 disposed on the smooth portion 70. Similar to the three-dimensional part 61, the index part 72 includes a convex part formed on the outer peripheral surface 42 a with a height of several hundred μm (for example, 500 μm). The indicator part 72 is arranged in a predetermined relative positional relationship with the three-dimensional part 61 in the circumferential direction. In other words, the indicator portion 72 is formed as an indicator in the circumferential direction when the contour portion 62 is formed along the contour of the three-dimensional portion 61.

  The outer peripheral surface 41a of the measuring tube portion 41 on the lid 44 side of the screwing portion 42 has a smoothing portion 73 arranged in a range where the measuring display portions 50A and 50B are arranged in the circumferential direction, and a weighing display in the circumferential direction. And knurled portions 74 disposed in a range where the portions 50A and 50B are not disposed. The knurled portion 74 has a plurality of protrusions that are arranged at regular intervals in the circumferential direction and extend substantially parallel to the central axis C. Since the knurled part 74 is arranged in a range where the weighing display parts 50A and 50B are not arranged, the graspability to the measuring cylinder part 41 is improved and the visibility of the contents injected into the measuring cylinder part 41 is improved. It can suppress that it falls by the knurled part 74. FIG.

Next, a method for producing the measuring cap 4 will be described with reference to FIGS.
FIG. 4 is a diagram in which the laser device 22 that irradiates the laser beam 20 to the measuring cap 4 having the lid portion 44 disposed on the lower side is disposed.
In the measurement cap 4, the three-dimensional part 61 of the measurement display parts 50 </ b> A and 50 </ b> B is formed in advance on the outer peripheral surface 41 a of the measurement cylinder part 41 by injection molding.

As the laser apparatus 22 shown in FIG. 4, for example, YVO4 laser marking MD-V9900 series manufactured by Keyence Corporation is used.
As an example, the laser device 22 can irradiate the laser beam 20 with three axes of freedom.
(Laser irradiation conditions)
・ Scanning speed: 2000mm / s
・ Printing time: 1800ms
・ Laser power: 85%
・ QSW frequency: 30 kHz
(Printing conditions)
・ Printing characters: Universal font ・ Character size: Width 2.76 x Height 4.44mm

  For example, in the production line, the measuring cap 4 is positioned in the direction of the central axis C when the lid portion 44 is supported by the support base 24. The measuring cap 4 is aligned with the three-dimensional portion 61 positioned at a predetermined position in the circumferential direction with the index portion 72 as an index. Thereby, as for the measurement cap 4, the solid part 61 is positioned about the central-axis C direction and the circumferential direction.

  When the three-dimensional part 61 is positioned, as shown in FIG. 4, from the laser device 22, for example, the symbols 54, 55, 56 of the weighing display part 50B (symbol 56 is not shown in FIG. 4) in the direction of the central axis C The laser beam 20 is irradiated toward the outer peripheral surface 41a at an irradiation angle corresponding to the position of the lens and the position in the circumferential direction.

  By applying the laser beam 20 having a focal position set to a desired depth to the outer circumferential surface 41a, the laser beam 20 is applied to the resin from the outer circumferential surface 41a of the measuring tube portion 41 to the inner portion as shown in FIG. It generates heat and the resin is carbonized and develops color. In this case, carbonization of the measuring tube portion 41 where the laser beam 20 is strongly applied (focal position) proceeds and a dark color is developed even inside. At this time, for example, by setting the focal position of the laser beam 20 between the outer peripheral surface 41a and the inner peripheral surface 41b in the radial direction around the central axis C, the focal position in the thickness direction of the measuring tube portion 41 is set. The resin is colored over the outer peripheral surface 41a.

  And by irradiating the laser beam 20 from the laser device 22 every predetermined time along the contour of the three-dimensional part 61 in the measuring cap 4, as an example, as shown in FIG. A contour portion 62 in which a plurality of colored dot portions D are arranged along the contour of the three-dimensional portion 61 is formed.

  When the contour portion 62 of the number “2” in the symbol 55 is formed, the contour portion 62 colored along the contour of the three-dimensional portion 61 with respect to the number “0” is formed in the same manner as the number “2”. Further, after the contour portion 62 is formed in the symbol 55, the contour portion 62 is sequentially formed for the symbol 56 and the symbol 54. Thereafter, like the symbols 54, 55, and 56, the measuring cap 4 is manufactured by forming the contour portion 62 for the symbols 51, 52, and 53.

In the measuring cap 4 having the above-described configuration, the symbol 60 has a three-dimensional portion 61 that protrudes three-dimensionally with respect to the outer peripheral surface 41a, and a contour portion 62 that is colored along the contour of the three-dimensional portion 61. The visibility of the symbol 60 is improved.
Therefore, in the measuring cap 4 of the present embodiment, the visibility is improved compared to the case where the symbol 60 is formed only by the three-dimensional part 61, and the symbol 60 is performed only by printing using the laser device 22. In comparison, it is possible to significantly reduce the number of rows of dots D, thereby suppressing energy consumption and improving productivity. In particular, in the measuring cap 4 of the present embodiment, not only the outer peripheral surface 41a but also the thickness direction of the measuring tube portion 41 is colored by the irradiation of the laser beam 20, so that the visibility can be further improved. is there.

  Moreover, in the measuring cap 4 of this embodiment, since the index part 72 formed by injection molding at the same time as the three-dimensional part 61 and the relative positional relationship is ensured is provided, the laser device 22 is used by using the index part 72. It is possible to align with the three-dimensional part 61. Therefore, in the measuring cap 4 of the present embodiment, the contour part 62 that is aligned with high accuracy with respect to the three-dimensional part 61 can be formed.

  In FIG. 5, the contour portion 62 in which the dot portions D are arranged in one row is illustrated, but a configuration in which the dot rows D are arranged in a plurality of rows according to the visibility of the symbol 60 may be employed.

As an example, the embossed portion 63 is subjected to an embossing process on the surface of a mold for molding the outer peripheral surface 41a of the measuring tube portion 41 by a chemical process such as etching, a physical process such as sandblasting, or a polishing process that does not have a mirror finish, and a measuring cap. 4 is formed by transferring the embossed surface to the outer peripheral surface 41a. Examples of the concavo-convex pattern of the embossed portion 63 include leather (scale), pear texture, wood grain, rock texture, sand texture, fabric pattern, and geometric pattern. As an unevenness | corrugation amount of the embossed part 63, it is 0.001-0.5 mm, for example.

The contour portion 62 irradiates the laser beam 20 from the laser device 22 at predetermined intervals along the contour of the three-dimensional portion 61 in the measuring cap 4, for example, as shown in FIG. A plurality of colored dot portions D are arranged along the contour of the 2 ”solid portion 61 (the embossed portion 63).
