JP, 2000-142741, A

However, in the measuring cap as described above, in the portion where the side peripheral wall projects toward the opening side (the lower side in FIG. 3 of Patent Document 1) with respect to the mounting cylinder (the portion where the side peripheral wall and the mounting cylinder do not overlap in the radial direction). Since there is nothing that blocks the outside light behind (outside) the side peripheral wall when viewed from the inside, the outside light is easily transmitted from the outside toward the inside of the side peripheral wall. Therefore, when the user looks into the inner peripheral surface of the side peripheral wall and reads the weighing scale, the background of the weighing scale becomes bright. This is particularly noticeable when the measuring cap is transparent or translucent. When the background of the weighing scale becomes bright, it becomes difficult to see the weighing scale, and the visibility of the weighing scale deteriorates.

The present invention has been made in view of the above points, and an object thereof is to improve the visibility of the above-described measuring scale of the measuring cap.

A measuring cap according to an aspect of the present invention is a measuring cap that is attached to a mouth of a container body, has a cylindrical wall, and has a detaching mechanism for attaching and detaching the measuring cap to the mouth of the container body. An outer cylinder part, an inner cylinder part that is located inside the outer cylinder part, has a cylindrical wall and a bottom wall, has an opening at the tip opposite to the bottom wall of the cylindrical wall, and is capable of storing liquid, The tubular wall of the inner tubular portion has a first tubular portion projecting in a direction from the bottom wall toward the opening more than the tubular wall of the outer tubular portion, and a first tubular portion overlapping the tubular wall of the outer tubular portion. And a tubular portion of the inner tubular portion, and the tubular wall of the inner tubular portion is graduated from the bottom wall toward the opening, and the tubular wall of the inner tubular portion is the first tubular portion. The wall thickness of at least a part of the cylindrical portion provided with the measuring scale is larger than the wall thickness of at least a part of the second tubular portion.

According to the present invention, the visibility of the measuring scale of the measuring cap can be improved.

<Overall structure of container>
FIG. 1 is an explanatory diagram showing a configuration near a mouth portion of a container 1 provided with a 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 10 a 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. In the present embodiment, the liquid is stored, and examples of the liquid include a liquid detergent, a liquid softening agent, a liquid bleaching agent, and the like. The main body container 10 includes a main body cap 20 at the mouth 10a. The body cap 20 has, for example, a cylindrical tubular 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 a pouring portion 32 having a U-shaped peripheral wall portion inside the tubular wall 30. The spout 32 is provided with a spout 33 at the tip opposite to the main body container 10. The spout 32 is longer than the tubular wall 30 and projects outward from the tubular wall 30.

<Structure of measuring cap>
FIG. 2 is a perspective view of the measuring cap 11 with an opening 62, which will be described later, facing upward, and FIG. 3 is a vertical cross-sectional view of the XX section of the measuring cap 11 of FIG. The measuring cap 11 has a double structure of an outer tubular portion 40 and an inner tubular portion 41 as shown in FIGS. 2 and 3, for example. The measuring cap 11 is made of resin, for example, and is transparent or translucent.

The outer tubular portion 40 has a tubular wall 50 having a substantially cylindrical shape. The outer tubular portion 40 has a screw portion 51 on the inner peripheral surface of the tubular wall 50, which serves as an attaching/detaching mechanism for being screwed into the body cap 20 of the container body 10. FIG. 4 shows the measuring cap 11 in a state in which the screw portion 51 of the outer cylinder portion 40 is screwed into the screw portion 31 of the body cap 20 of the container body 10.

As shown in FIGS. 2 and 3, the inner tubular portion 41 is provided inside the outer tubular portion 40. The inner tubular portion 41 has a tubular tubular wall 60 and a bottom wall 61 that closes one end of the tubular wall 60. Further, the bottom wall 61 closes the mouth 10 a of the container body 10 and seals the container body 10. An end portion of the cylindrical wall 60 on the opposite side (tip end side) to the bottom wall 61 is opened to form an opening 62 for taking in and out the liquid. The inner cylinder portion 41 can store the liquid that has entered through the opening 62.

As shown in FIG. 3, the tubular wall 60 of the inner tubular portion 41 is longer than the tubular wall 50 of the outer tubular portion 40, and the direction from the bottom wall 61 to the opening 62 is larger than that of the tubular wall 50 (FIGS. It projects in the tip direction A) shown in FIG. That is, the tubular wall 60 of the inner tubular portion 41 overlaps the first tubular portion 70 protruding in the distal direction A from the tubular wall 50 of the outer tubular portion 40 and the tubular wall 50 of the outer tubular portion 40. It has a second tubular portion 71. The tubular wall 50 of the outer tubular portion 40 is positioned radially outward (the direction from the central axis of the tubular wall 50 to the outside perpendicular to the central axis) with respect to the second tubular portion 71. It exists in the direction from the bottom wall 61 to the opening 62. In the present embodiment, the bottom wall 61 of the inner tubular portion 41 is located at substantially the same position as the rear end (rear end side) opposite to the front end direction A of the tubular wall 50 of the outer tubular portion 40, The tubular wall 60 of the inner tubular portion 41 projects only in one direction (tip direction A) with respect to the tubular wall 50 of the outer tubular portion 40. Further, in the present embodiment, the length of the first tubular portion 70 is formed longer than the length of the second tubular portion 71.

A measuring scale 80 is provided from the bottom wall 61 toward the opening 62 on the inner peripheral surface side of the tubular wall 60 of the inner tubular portion 41. The “inner peripheral surface side of the tubular wall 60” here includes not only the inner surface of the tubular wall 60 but also the interior near the inner surface of the tubular wall 60. The measuring scale 80 is printed by laser marking, for example. Laser marking is for printing by irradiating a laser light to a color former mixed in advance with the material of the measuring cap 11. A plurality of weighing scales 80 are provided from the second tubular portion 71 to the first tubular portion 70 in the distal direction A. For example, the measuring scale 80 is provided on both the second tubular portion 71 and the first tubular portion 70. In the present embodiment, an example in which three weighing scales 80 of “30”, “45” and “55” are attached is shown in FIG. 3, but the number, position, numerical value, pattern and size of the weighing scales are shown. Etc. are not limited to this.

The tubular wall 60 of the inner tubular portion 41 is configured such that the wall thickness D1 of the first tubular portion 70 is larger than the wall thickness D2 of the second tubular portion 71. For example, the wall thickness D2 of the second tubular portion 71 is, for example, about 0.5 mm or more and 0.8 mm or less, and is constant in the tip direction A. On the other hand, the wall thickness D1 of the first tubular portion 70 gradually increases from the connection end portion with the second tubular portion 71 toward the opening 62, for example. That is, the wall thickness D1 of the first tubular portion 70 is larger than the wall thickness D2 of the second tubular portion 71, and the connection of the first tubular portion 70 with the second tubular portion 71 is made. The end portion has the smallest wall thickness, and the tip portion of the first tubular portion 70 on the opening 62 side has the largest wall thickness. The wall thickness D1 of the first tubular portion 70 is preferably, for example, 0.6 mm or more and 1.2 mm or less. The thickness D1 of the thickest portion of the first tubular portion 70 is preferably 1.2 times or more the thickness D2 of the second tubular portion 71.

In the present embodiment, the inner diameter R1 of the first tubular portion 70 and the second tubular portion 71 is constant. The outer diameter R2 of the first tubular portion 70 gradually increases toward the distal end direction A as the wall thickness D1 increases, and the outer peripheral surface of the first tubular portion 70 gradually moves outward as it approaches the opening 62. It is inclined to spread over.

Then, when using the container 1 having the above-described configuration, the user can remove the measuring cap 11 from the state in which the measuring cap 11 is screwed into the main body cap 20 at the mouth 10a of the main body 10 as shown in FIG. The measuring cap 11 is turned to remove the measuring cap 11 from the container body 10 as shown in FIG. Next, as shown in, for example, FIGS. 2 and 3, the user pours the liquid in the container body 10 into the inner tubular portion 41 with the opening 62 of the inner tubular portion 41 of the measuring cap 11 facing upward. At this time, for example, as shown in FIG. 5, the user looks into the inner peripheral surface of the tubular wall 60 of the inner tubular portion 41 and reads the weighing scale 80.

According to the present embodiment, the wall thickness D1 of the first tubular portion 70 of the tubular wall 60 of the inner tubular portion 41 projecting beyond the tubular wall 50 of the outer tubular portion 40 is equal to the second tubular portion. Since the thickness is greater than the wall thickness D2 of 71, it is possible to prevent external light from passing through the tubular wall 60 of the inner tubular portion 41 from the outside to the inside in the first tubular portion 70. As a result, when the user looks into the inner peripheral surface of the tubular wall 60 of the inner tubular portion 41 to read the weighing scale 80, the background of the weighing scale 80 of the first tubular portion 70 becomes dark and the weighing scale 80 is visible. It will be easier. Therefore, the visibility of the weighing scale 80 can be improved.

In the present embodiment, as shown in FIG. 3, the wall thickness of the tubular portion of the first tubular portion 70 having the weighing scale 80 (“55” of the weighing scale) closest to the opening 62. D1 is thicker than the wall thickness D2 of the second tubular portion 71. The tubular portion near the opening 62 is separated from the tubular wall 50 of the outer tubular portion 40, and normally, the tubular wall 60 of the inner tubular portion 41 is directed from the outer side to the inner side from the direction in which the external light is more. However, by increasing the wall thickness D1 of the tubular portion near the opening 62, more external light is blocked by the tubular wall 60 of the inner tubular portion 41 in the tubular portion near the opening 62. It As a result, the weighing scale 80 near the opening 62 can be easily seen, and the visibility of the weighing scale 80 can be improved.

Further, in the present embodiment, the overall wall thickness D1 of the first tubular portion 70 is thicker than the wall thickness D2 of the second tubular portion 71, so the tubular wall of the outer tubular portion 40 is formed. All the measuring scales 80 attached to the first tubular portion 70 projecting more than 50 can be surely easily seen, and the visibility of the measuring scales 80 can be further improved.

The inner wall R1 of the tubular wall 60 of the inner tubular portion 41 is constant, and the outer diameter R2 of the thick wall portion (first tubular portion 70) is large. Therefore, even if the wall thickness of the tubular wall 60 of the inner tubular portion 41 becomes thick, the inner diameter R1 does not change, so that high weighing accuracy of the weighing cap 11 can be maintained.

The measuring scale 80 is printed by laser marking. The measuring scale 80 printed by laser marking has a relatively light color, and light tends to easily pass through the printed portion. On the other hand, the laser marking is excellent in performing printing on a narrow place such as the inner peripheral surface of the inner cylinder portion 41. Therefore, according to the present embodiment, it is possible to improve the visibility of the weighing scale 80 while preferably printing the weighing scale 80 on the inner peripheral surface of the tubular wall 60 of the inner tubular portion 41.

The measuring cap 11 is made of transparent or translucent synthetic resin. Thereby, at least the tubular wall 60 of the inner tubular portion 41 is transparent or translucent. When the tubular wall 60 of the inner tubular portion 41 is transparent or translucent, in the first tubular portion 70 of the inner tubular portion 41 provided with the scale 80, outside light is generally transmitted from the outside to the inside. Although it becomes easier, the visibility of the measuring scale 80 can be dramatically improved by increasing the wall thickness D1 of the first tubular portion 70 and blocking more external light.

The preferred embodiment of the present invention has been described above with reference to the accompanying drawings, but the present invention is not limited to such an example. It is obvious to those skilled in the art that various changes or modifications can be conceived within the scope of the idea described in the claims, and naturally, they also belong to the technical scope of the present invention. Understood.

For example, in the above-described embodiment, the entire wall thickness of the first tubular portion 70 is larger than the wall thickness of the second tubular portion 71, but a part of the first tubular portion 70 is The wall thickness may be larger than the wall thickness of the second tubular portion 71. For example, as shown in FIG. 6, of the first tubular portion 70, only the wall thickness D1 of the tubular portion at a predetermined distance H from the end on the side of the opening 62 is smaller than the wall thickness D2 of the second tubular portion 71. May be thicker. The predetermined distance H may be, for example, 1/2 or more, preferably 2/3 or more, more preferably 4/5 or more of the total length L of the first tubular portion 70. Further, the predetermined distance H may be a distance including all the measuring scales 80 attached to the first tubular portion 70 (the measuring scales of “45” and “55” in the present embodiment). That is, the wall thickness of the portion of the first tubular portion 70 including all the measuring scales 80 attached to the first tubular portion 70 is larger than the wall thickness of at least a portion of the second tubular portion 71. It may be thicker.

In the above-described embodiment, the wall thickness D1 of the first tubular portion 70 is gradually increased in the distal direction A, but the thickness is not limited to this. For example, as shown in FIG. 7, the thickness D1 of the thick portion of the first tubular portion 70 may be constant. In this case, the outer diameter R2 of the thick portion of the first tubular portion 70 is also constant.

In the above-described embodiment, the wall thickness D2 of the second tubular portion 71 is constant, but may vary. For example, the thickness of the second tubular portion 71 on the rear end side opposite to the tip direction A is thin, and the thickness of the second tubular portion 71 on the connection portion side with the first tubular portion 70 is large. Good. At this time, the thickness of the second tubular portion 71 on the side of the connecting portion with the first tubular portion 70 may be equal to the thickness D1 of the first tubular portion 70.

Further, although the measuring scale 80 was printed by laser marking, the present invention can be applied to printing by other methods such as hot stamping and engraving. Although the weighing scale 80 is attached to both the first tubular portion 70 and the second tubular portion 71, it may be attached only to the first tubular portion 70. Further, the measuring cap 11 is not limited to being transparent or semi-transparent, and light may pass through the tubular wall 60 of the inner tubular portion 41, for example, because of its thin wall thickness and light color.

The configurations of the outer tubular portion 40 and the inner tubular portion 41 of the measuring cap 11 in the above-described embodiment are not limited to those in the above-described embodiment. For example, as shown in FIG. 8, the bottom wall 61 of the inner tubular portion 41 is located relatively rearward (opposite to the front end direction A) with respect to the rear end of the tubular wall 50 of the outer tubular portion 40. The tubular wall 60 of 41 may project in both directions (the front end direction A and the rear end direction) with respect to the tubular wall 50 of the outer tubular portion 40. That is, the tubular wall 60 of the inner tubular portion 41 further has a third tubular portion 72 projecting from the tubular wall 50 of the outer tubular portion 40 in the direction from the opening 62 toward the bottom wall 61. The third tubular portion 72 may have a scale 80, and the wall thickness D3 of the third tubular portion 72 may be the same as the wall thickness D2 of the second tubular portion 71. .. Further, for example, when the third tubular portion 72 has the weighing scale 80, the wall thickness D3 of at least a part of the cylindrical portion of the third tubular portion 72 to which the weighing scale 80 is attached is It may be thicker than the wall thickness D2 of at least a part of the second tubular portion 71. In the third tubular portion 72, the total thickness D3 of the third tubular portion 72 is the same as the thickness D1 of the first tubular portion 70. It may be configured to be thicker than D2.

The configurations of the container 1 and the container body 10 are not limited to those in the above embodiment. For example, in the above-described embodiment, the mouth 10a of the container body 10 has the body cap 20, but it may not have the body cap 20. In this case, for example, the threaded portion of the measuring cap 11 is screwed into the threaded portion directly provided on the outer peripheral surface of the opening 10a of the container body 10 to attach the measuring cap 11 to the container body 10. Further, the detaching mechanism for detaching the measuring cap 11 from the mouth portion 10a of the container body 10 is not limited to a screwing portion such as a screw portion, and other known attachment and detaching mechanisms may be used. It may be a mechanism.

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