In addition, the following embodiments are examples for explaining the present invention, and the present invention is not limited to this embodiment.

<Overall composition of the container>
FIG. 1 is an explanatory view showing a configuration in the vicinity of the mouth portion of the container 1 provided with the measuring cap according to the present embodiment.

As shown in FIG. 1, the container 1 includes a main body container 10 and a measuring cap 11 that can be attached to the mouth portion 10a of the main body container 10. The main body container 10 is made of resin, for example, and can store contents such as liquid and powder. Examples of liquids in the contents include liquid detergents, fabric softeners, liquid bleaches and the like. The main body container 10 is provided with a main body cap 20 at the mouth portion 10a. The main body cap 20 has, for example, a cylindrical cylindrical wall 30, and a screw portion 31 for screwing the measuring cap 11 is provided on the outer peripheral surface of the cylindrical wall 30. Further, the main body cap 20 has an ejection portion 32 having a U-shaped peripheral wall portion inside the tubular wall 30. The pouring portion 32 is provided with a spout 33 at its tip. The dispensing portion 32 is longer than the tubular wall 30 and projects toward the tip end side of the main body container 10 from the tubular wall 30. In the present specification, regarding the configuration of the main body container 10, the side with the mouth portion 10a of the main body container 10 (upper side in FIG. 1) is referred to as the “tip side”.

<Structure of weighing cap>
FIG. 2 is a perspective view of the measuring cap 11 with the opening 52, which will be described later, facing up, and FIG. 3 is a vertical sectional view of the XX cross section of the measuring cap 11 of FIG. The measuring cap 11 has an inner cylinder portion 40 and an outer cylinder portion 41 as shown in FIGS. 1 to 3, for example. The measuring cap 11 is made of resin, for example, and has light transmission property. The inner cylinder portion 40 corresponds to the "cylinder portion" in the present invention, and the outer cylinder portion 41 corresponds to the "other cylinder portion".

The inner tubular portion 40 has a cylindrical tubular wall 50 and a bottom wall 51 in which one end of the tubular wall 50 is closed. The tip of the tubular wall 50 on the opposite side of the bottom wall 51 is an opening 52 for taking in and out liquid. The inner cylinder portion 40 can store the contents entered through the opening 52. In the present specification, regarding the configuration of the measuring cap 11, the bottom wall 51 side of the measuring cap 11 is referred to as the “bottom side” and the opening 52 side is referred to as the “tip side”.

A weighing scale 70 is attached to the inner peripheral surface 60 of the tubular wall 50. A plurality of measuring scales 70 are linearly attached from the bottom side to the tip side of the tubular wall 50. In this embodiment, three weighing scales 70 of "30", "45", and "55" are attached. The weighing scale 70 is attached so that the characters such as "30" face the tip end side of the tubular wall 50. It should be noted that "the weighing scale 70 is attached to the inner peripheral surface 60 of the tubular wall 50" is not limited to the case where the weighing scale 70 is attached to the surface of the inner peripheral surface 60, but also the tubular wall 50. A case where a weighing scale 70 is provided inside the vicinity of the surface of the inner peripheral surface 60 of the above is also included. The number, position, numerical value, pattern, size, etc. of the weighing scale 70 are not limited to this.

The weighing scale 70 is, for example, printed by laser marking from the inner peripheral surface 60 side of the tubular wall 50. The laser marking is printed by irradiating a color former mixed with the material of the measuring cap 11 with a laser beam. If the weighing scale 70 is visible on the inner peripheral surface 60 side of the tubular wall 50, it is printed from the outer peripheral surface 61 side even if it is not printed from the inner peripheral surface 60 side of the tubular wall 50. You may.

The tubular wall 50 is configured so that the thickness D varies along the circumferential direction. That is, the tubular wall 50 has a thick portion 90 having a relatively thick thickness D as shown in FIG. For example, when the tubular wall 50 is viewed from the tip side, the inner peripheral surface 60 and the outer peripheral surface 61 of the tubular wall 50 each have a circular shape, and the circular center P1 of the inner peripheral surface 60 and the circular center P2 of the outer peripheral surface 61 are respectively. Is slightly off. As a result, the thickness D of the tubular wall 50 fluctuates in the circumferential direction. The tubular wall 50 starts from the thinnest portion S1 having the thinnest thickness D, gradually becomes thicker in the clockwise direction, and becomes the largest at a point advanced by 180 ° (thickest portion S2), and from there. Further, it gradually becomes thinner as it advances clockwise, and is configured to become the thinnest in the original thinnest portion S1 which is 180 ° ahead of the thickest portion S2.

The weighing scale 70 is attached to a thick portion 90 of the tubular wall 50. The thickness D of the wall thickness portion 90 with the weighing scale 70 is set to, for example, 0.4 mm or more and 1.2 mm or less, preferably 0.5 mm or more and 1.0 mm or less, and more preferably 0.6 mm or more and 0.8 mm or less. Has been done. In the present embodiment, for example, in the tubular wall 50, the wall thickness portion is 90 ° in the circumferential direction (semi-arc) about the reference line B passing through the thickest portion S2 (measurement scale 70) and the center P1. It is 90.

The tubular wall 50 has a thin portion 91 at a portion facing the thick portion 90. The thickness D of the thin portion 91 without the weighing scale 70 is set to, for example, 0.3 mm or more and 0.9 mm or less, preferably 0.4 mm or more and 0.8 mm or less. In the present embodiment, for example, in the tubular wall 50, the thin portion 91 has a 90 ° range (semi-arc) in the circumferential direction about the reference line B passing through the thinnest portion S1 (measurement scale 70) and the center P1. is there. The thin portion 91 is transparent or translucent depending on the material and its thickness.

As shown in FIGS. 1 to 3, the outer cylinder portion 41 has a tubular wall 100 as another substantially cylindrical tubular wall extending from the bottom side to the tip end side. The tubular wall 100 has the same axis as the tubular wall 50, and is provided so as to surround the outer periphery of the tubular wall 50. From the side view (when the tubular walls 50 and 100 are viewed from the outside in the radial direction), the position of the bottom end portion of the tubular wall 100 and the position of the bottom wall 51 of the tubular wall 50 are substantially the same. The axial length (tip direction) of the tubular wall 100 is shorter than that of the tubular wall 50, and the tubular wall 100 is arranged so as to overlap only the bottom portion of the tubular wall 50 in a side view. .. As a result, the tubular wall 50 of the inner tubular portion 40 has an exposed portion 50a that does not overlap with the tubular wall 100 of the outer tubular portion 41 in a side view, and the weighing scale 70 is provided on the inner peripheral surface 60 of the exposed portion 50a. A part of is attached.

The outer cylinder portion 41 has a screw portion 101 as an attachment / detachment mechanism for screwing into the main body cap 20 of the container main body 10 on the inner peripheral surface of the tubular wall 100. FIG. 5 shows a measuring cap 11 in a state in which the screw portion 101 of the outer cylinder portion 41 is screwed into the screw portion 31 of the main body cap 20 of the container main body 10.

As shown in FIG. 4, the outer cylinder portion 41 has a circular inner peripheral surface 110 and an outer peripheral surface 111 when viewed from the tip side, and is a circular center of the inner peripheral surface 110 and the outer peripheral surface 111 of the outer cylinder portion 41. Is coincident with the center P1 of the inner peripheral surface 60 of the tubular wall 50 of the inner cylinder portion 40.

Then, when using the container 1 having the above configuration, the user can use the measuring cap 11 from the state where the measuring cap 11 is screwed into the main body cap 20 at the mouth portion 10a of the container main body 10 as shown in FIG. The measuring cap 11 is turned and the measuring cap 11 is removed from the container body 10 as shown in FIG. Next, for example, as shown in FIGS. 2 and 3, the user pours the liquid of the container body 10 into the inner cylinder portion 40 with the opening 52 of the inner cylinder portion 40 of the measuring cap 11 facing upward. At this time, for example, as shown in FIG. 3, the user looks into the inner peripheral surface 60 of the tubular wall 50 of the inner tubular portion 40, or reads the weighing scale 70 through the thin portion 91 of the tubular wall 50.

According to the present embodiment, the thickness D of the tubular wall 50 of the inner tubular portion 40 varies in the circumferential direction, and the tubular wall 50 has a wall thickness portion 90 that is relatively thick. Since the measuring scale 70 is attached to the portion 90, it is possible to prevent outside light from passing through the inside of the inner cylinder portion 40. As a result, when the user looks into the inner cylinder portion 40 and reads the weighing scale 70, the background of the weighing scale 70 becomes dark and the weighing scale 70 becomes easier to see. Therefore, the visibility of the weighing scale 70 can be improved.

Since the inner peripheral surface 60 of the tubular wall 50 has a circular shape and it is easy to accurately grasp the amount of liquid contained in the tubular wall 50, it is possible to maintain high weighing accuracy of the measuring cap 11.

When the tubular wall 50 is viewed from the tip side, the inner peripheral surface 60 and the outer peripheral surface 61 of the tubular wall 50 each have a circular shape, and the circular center P1 of the inner peripheral surface 60 and the circular center P2 of the outer peripheral surface 61 are displaced from each other. As a result, the thickness of the tubular wall 50 varies in the circumferential direction. In this case, even if the thickness D of the tubular wall 50 is changed in the circumferential direction, the shape of the measuring cap 11 is not complicated, and the measuring cap 11 can be manufactured easily and at low cost. Further, both the thick portion 90 and the thin portion 91 of the tubular wall 50 can be easily molded.

The wall-thick portion 90 to which the weighing scale 70 is attached preferably has a thickness of 0.4 mm or more and 1.2 mm or less. When the thick portion 90 is in this range, external light can be reliably blocked. As a result, the visibility of the weighing scale 70 can be reliably improved. Further, the thick portion 90 does not become too thick, and the manufacturing cost can be reduced.

The tubular wall 50 has a thin portion 91 having a relatively thin thickness in a region facing the thick portion 90, and the thin portion 91 is transparent or translucent, so that the user can use it as shown in FIG. The weighing scale 70 inside the tubular wall 50 can be visually recognized from the outside of the tubular wall 50 through the thin portion 91 of the tubular wall 50. As a result, the visibility of the weighing scale 70 can be further improved.

The thin portion 91 preferably has a thickness of 0.3 mm or more and 0.9 mm or less. When the thin portion 91 is in this range, the user can more reliably visually recognize the weighing scale 70 from the outside of the tubular wall 50 through the thin portion 91 of the tubular wall 50. Further, the strength of the tubular wall 50 can be sufficiently ensured.

The measuring cap 11 includes an outer cylinder portion 41 having a detaching mechanism for attaching / detaching the measuring cap 11 to / from the mouth portion 10a of the container body 10, and the tubular wall 50 of the inner cylinder portion 40 is a side view of the outer cylinder. It has an exposed portion 50a that does not overlap with the tubular wall 100 of the portion 41, and a weighing scale 70 is attached to the exposed portion 50a. Generally, in the exposed portion 50a of the tubular wall 50, there is nothing to block outside light on the outside and it is easy to transmit. However, in this embodiment, the exposed portion 50a is provided with the thick portion 90, and the thick portion 90 is provided with the thick portion 90. Since the weighing scale 70 is attached, the visibility of the weighing scale 70 can be effectively improved.

The weighing scale 70 is attached so that the upper part of the character faces the tip end side of the tubular wall 50. As a result, when the weighing cap 11 is attached to the container body 10, the characters of the weighing scale 70 are turned upside down as shown in FIG. 1, but the weighing scale 70 is attached to the inner peripheral surface 60 of the tubular wall 50. Therefore, it becomes difficult to see from the outside, and the design of the measuring cap 11 can be improved.

The weighing scale 70 is printed by laser marking. The weighing scale 70 printed by laser marking has a relatively light color and tends to allow light to easily pass through the printed portion. On the other hand, laser marking is excellent in printing in a narrow place such as the inner peripheral surface 60 of the inner cylinder portion 40. Therefore, according to this embodiment, it is possible to improve the visibility of the weighing scale 70 while suitably printing the weighing scale 70 on the inner peripheral surface 60 of the tubular wall 50 of the inner cylinder portion 40.

The measuring cap 11 is made of a light-transmitting material. In this case, external light is generally easily transmitted through the tubular wall 50, but more external light is blocked by forming the portion of the tubular wall 50 with the measurement scale 70 as the thick portion 90. Therefore, the visibility of the weighing scale 70 can be effectively improved.

Although preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to such examples. It is clear that a person skilled in the art can come up with various modifications or modifications within the scope of the ideas described in the claims, and these also naturally belong to the technical scope of the present invention. It is understood as a thing.

For example, in the above embodiment, the thickness D of the tubular wall 50 fluctuates in the circumferential direction due to the deviation of the circular center P1 of the inner peripheral surface 60 of the tubular wall 50 and the circular center P2 of the outer peripheral surface 61. The configuration in which the thickness D of the shaped wall 50 is varied in the circumferential direction is not limited to this. For example, as shown in FIG. 6, a part of the outer peripheral surface 61 of the tubular wall 50 may protrude outward in the radial direction (direction away from the center P1) to form the thick portion 90. The thick portion 90 is formed in an arcuate range having an internal angle θ1 in the circumferential direction of the tubular wall 50. The internal angle θ1 is preferably 60 ° or more and 90 ° or less. The wall-thick portion 90 is formed symmetrically about a reference line B passing over the weighing scale 70.

Further, as shown in FIG. 7, a thin portion 91 may be formed by denting a part of the outer peripheral surface 61 of the tubular wall 50 inward in the radial direction (direction approaching the center P1). The thin portion 91 is formed in an arcuate range having an internal angle θ2 in the circumferential direction of the tubular wall 50. The internal angle θ2 is preferably 60 ° or more and 90 ° or less. The wall-thick portion 91 is formed symmetrically about a reference line B passing over the weighing scale 70.

The variation in the thickness D of the tubular wall 50 in the circumferential direction may include the thick portion 90 and the thin portion 91 by causing the inner peripheral surface 60 to protrude outward or to be recessed inward. Further, the thick portion 90 and the thin portion 91 may be formed by making both the outer peripheral surface 61 and the inner peripheral surface 60 uneven. As shown in FIGS. 4, 6 and 7, it is preferable that there is no uneven portion on the inner peripheral surface in order to facilitate scale formation.

In the above embodiment, the difference ΔD between the maximum thickness of the thick portion 90 with the weighing scale 70 and the minimum thickness of the thin portion 91 is set to, for example, 0.1 mm or more and 0.7 mm or less. May be good. Further, the thin portion 91 does not have to be transparent or translucent.

The measuring cap 11 in the above embodiment may have another configuration. For example, the outer cylinder portion 41 of the measuring cap 11 is arranged on the bottom side of the inner cylinder portion 40 in a side view, but may be arranged on the tip side or near the middle of the inner cylinder portion 40. The length of the outer cylinder portion 41 in the tip direction is also not limited to that of the above embodiment.

Further, the measuring cap 11 may include a tip cylinder portion 120 as another cylinder portion as shown in FIGS. 8 and 9 instead of the outer cylinder portion 41. The tip cylinder portion 120 is connected to the tip portion of the inner cylinder portion 40 having an opening 52. The tip tubular portion 120 has a cylindrical tubular wall 130. The tubular wall 130 is connected to, for example, the tip of the inner tubular portion 40 (cylindrical wall 50) and is connected to a reduced diameter portion 130a that gradually reduces in diameter toward the tip side and a tip of the reduced diameter portion 130a. It has the same diameter portion 130b having a constant diameter toward the side. On the outer peripheral surface of the same diameter portion 130b, a screw portion 131 is provided as an attachment / detachment mechanism for attaching / detaching the measuring cap 11 to / from the mouth portion 10a of the container body 10. Other configurations of the measuring cap 11 are the same as those in the above embodiment, and the same reference numerals are used and the description thereof will be omitted. In this example as well, when the user looks into the inner cylinder portion 40 and reads the weighing scale 70, the background of the weighing scale 70 becomes dark due to the thick portion 90, and the weighing scale 70 becomes easier to see. Visibility can be improved. Further, when there is a tip tubular portion 120 as in this example, the user makes the thin portion 91 transparent or translucent, although the distance from the opening at the tip of the tubular wall 130 to the weighing scale 70 becomes long. As a result, there is a great merit that the weighing scale 70 can be visually recognized through the thin portion 91 without the user looking into the inside of the inner tubular portion 40 from the opening at the tip of the tubular wall 130.

Further, although the weighing scale 70 was printed by laser marking, the present invention can also be applied to those printed by other methods such as hot stamping and engraving. Further, the weighing scale 70 may be attached to the outer peripheral surface 61 of the tubular wall 50. The material of the measuring cap 11 is not limited to that having light transmission.

The configurations of the container 1 and the container body 10 are not limited to those of the above embodiment. For example, in the above embodiment, the mouth portion 10a of the container main body 10 has the main body cap 20, but the container main body 10 may not have the main body cap 20. In such a case, for example, the screw portion of the measuring cap 11 is screwed into the screw portion directly provided on the outer peripheral surface of the mouth portion 10a of the container body 10, and the measuring cap 11 is attached to the container body 10. Further, the attachment / detachment mechanism for attaching / detaching the measuring cap 11 to / from the mouth portion 10a of the container body 10 is not limited to a screw portion such as a screw portion, and other known attachment / detachment mechanisms that engage or fit with each other. It may be a mechanism.

The present invention is useful in improving the visibility of the weighing scale of the measuring cap.
