Description

FIELD OF THE INVENTION The present invention relates to articles, containers and labels.

"Moiré" is interference fringes that visually appear when multiple periodic patterns or structures are superimposed. In addition, physically speaking, moiré can be said to be a beat phenomenon of two spatial frequencies. There are cases where moire is removed as undesirable, but there are also cases where the generated moire is used as something useful.

As an example of using moire as a useful thing, Patent Document 1 discloses moiré by superimposing a transparent sheet provided with a second pattern on a sheet-like base material provided with a first pattern. A pair of sheets for a decorative display is described.

Further, as another example, Patent Document 2 describes a decorative body including a hidden picture sheet containing a hidden picture and a lens sheet containing a plurality of lenses.

FIG. 1 is a cross-sectional view schematically showing an article according to an embodiment of the invention.
The article 1 shown in FIG. 1 includes a label 2, a container body 3, contents 4, and a lid 5.

The diameter of the shoulder portion decreases from the lower end to the upper end. A neck portion is connected to the upper end of the shoulder portion. The neck has a male thread on its outer peripheral surface. The body also includes a pair of walls facing each other in parallel.

The container body 3 is made of plastic or glass, for example. The plastic is preferably polyethylene terephthalate (PET). The container body 3 is, for example, a bottle or a water tank. Preferably, the container body 3 is a plastic bottle for beverages.

The container body 3 has optical transparency. Specifically, the container body 3 has visible light transmittance. Note that hereinafter, unless otherwise specified, the term "light" means visible light. The container body 3 may be transparent or light-scattering. It is preferable that the container body 3 is transparent.

The label 2 is supported by the container body 3. Specifically, the label 2 is supported by the body of the container body 3. Here, the label 2 is wrapped around the body of the container body 3. When supported by the container body 3, the label 2 includes a first pattern supported by one of the pair of walls described above and a second pattern supported by the other of the pair of walls described above. There is. Moreover, when the second pattern is observed through the first pattern and the contents 4 in a state where the label 2 is supported by the container body 3, the overlapping of the first pattern and the second pattern causes moiré. . The first pattern and the second pattern will be described later.

The contents 4 are housed in the container body 3. The contents 4 have visible light transmittance. Moreover, the content 4 is not air. Although the content 4 is liquid here, it is not limited to liquid, and may be solid or semi-solid. A semi-solid is one that has the physical properties of both a liquid and a solid. A semi-solid is, for example, a jelly. The liquid is, for example, a beverage such as water, or oil. Further, the contents 4 may be transparent or light scattering.

The refractive index n2 is, for example, greater than 1.0 and less than or equal to 1.5. For example, the refractive index of water is 1.33, and the refractive index of salad oil is 1.47.

The refractive index can be measured by the minimum deviation angle method, the critical angle method, the V-block prism method, the immersion method, the simulation method, and other known measurement methods. The angle method is more preferred. Moreover, the refractive index is a refractive index for light having a wavelength of 589.3 nm.

The lid 5 has a female thread on its inner circumferential surface that is screwed into a male thread of the neck of the container body 3. Thereby, the lid 5 is fixed to the neck of the container body 3.

FIG. 2 is an exploded view schematically showing the label 2 included in the article 1 shown in FIG. FIG. 3 is an enlarged view of the first pattern 21 included in the label 2 shown in FIG. The direction D shown in FIG. 3 is the height direction of the article 1. According to one example, when the bottom of the container body 3 is placed down, the height direction of the article 1 is the same direction as the direction of gravity applied to the article 1.

The label 2 includes a base material 20 and a printing pattern printed on the base material 20. Here, the print pattern includes a first pattern 21 and a second pattern 22.

The base material 20 may be transparent or translucent. The base material 20 may be partially opaque as long as the second pattern 22 can be visually recognized through the first pattern 21 and the contents 4.

The base material 20 is preferably transparent. The substrate 20 consists of polyethylene terephthalate (PET), polypropylene (PP), polycarbonate (PC) or polyvinyl chloride (PVC), according to one example. Alternatively, the substrate 20 is cellophane or tracing paper, according to other examples. The base material 20 is preferably made of polyethylene terephthalate (PET). The base material 20 may be soft or hard.

The light transmittance of the base material 20 is preferably 70% or more, more preferably 80% or more. Here, the light transmittance means the ratio of the intensity of transmitted light to the intensity of incident light. Attenuation of incident light may occur due to phenomena such as light diffusion and absorption. Here, the wavelength of the light is within the range of 380 nm to 780 nm.

The refractive index of the base material 20 is preferably less than 1.7, more preferably within the range of 1.5 to 1.65. For example, the refractive index of the base material 20 made of polyethylene terephthalate (PET) is 1.65.

Although the thickness of the base material 20 is not particularly limited, it is preferably within the range of 0.1 mm to 0.5 mm, and more preferably within the range of 0.2 mm to 0.4 mm.

The haze of the base material 20 is not particularly limited, but is preferably less than 55, more preferably less than 35. Note that haze is a value obtained by a method based on JIS K7136:2000.

The printed pattern may be made of water-based ink or oil-based ink. Additionally, the printed pattern may be made of temperature-sensitive ink. When temperature-sensitive ink is used, it is possible to create moiré at a specific temperature. Alternatively, the printed pattern may be made of resin.

The light transmittance of the printed pattern is preferably 70% or less, more preferably 0% or more and 30% or less. Further, the thickness of the printed pattern is preferably 0.5 mm or less.

As shown in FIG. 2, the label 2 includes a first portion A1 including a first pattern 21, a second portion A2 including a second pattern 22, a third portion A3, a fourth portion A4, and a pasting area. It includes part G. The margin portion G is located at one end of the label 2, and is adjacent to the first portion A1 with the fourth portion A4, the second portion A2, and the third portion A3 interposed therebetween in this order. Adhesive is provided in the adhesive portion G. The margin portion G and the end of the first portion A1 are bonded together with an adhesive.

The first pattern 21 is made up of a plurality of first pattern elements 210. The plurality of first pattern elements 210 are arranged periodically. Here, the first pattern elements 210 each have a shape extending in one direction and are arranged in the width direction. Specifically, the first pattern elements 210 are linear and arranged at a constant pitch in the width direction. The first pattern element 210 may have a curved shape such as a wave shape. The first pattern elements 210 may be arranged in two directions that intersect with each other. For example, the first pattern elements 210 each have a dot shape, and may be arranged at a constant pitch in two directions perpendicular to each other. In this case, the shape of the first pattern element 210 may be circular or square. Alternatively, the first pattern elements 210 may each have a shape extending in one direction, forming a grid pattern.

The second pattern 22 is made up of a plurality of second pattern elements 220. Here, the second pattern elements 220 are each linear and arranged in the width direction. Each of the second pattern elements 220 may be straight, folded or curved. The second pattern elements 220 each have a dot shape and may be arranged two-dimensionally. In this case, the shape of the second pattern element 220 may be circular or square.

As shown in FIG. 2, the arrangement of the first pattern elements 210 is inclined with respect to the height direction of the article 1. Further, as shown in FIG. 2, the arrangement of the second pattern elements 220 is inclined with respect to the height direction of the article 1. These will be detailed later.

For example, when this article 1 is observed from a direction perpendicular to the height direction D so that the first pattern 21 and the second pattern 22 overlap, the first pattern 21 and the second pattern 22 are different from each other. Superimposition causes moiré. Since the first pattern 21 and the second pattern 22 are spaced apart from each other, for example, when the article 1 is rotated around an axis parallel to the height direction D, the moire moves accordingly.

In the article 1, the arrangement of the first pattern elements 210 or the arrangement of the second pattern elements 220 is inclined with respect to the height direction D. That is, the arrangement of the first pattern elements 210 or the arrangement of the second pattern elements 220 is inclined with respect to the rotation axis passing through the center of the container body 3 and parallel to its height direction. When this array is tilted with respect to the rotation axis, the apparent pitch of the first pattern elements 210 or the second pattern elements 220 becomes larger compared to the actual pitch. Therefore, the moire displayed by the article 1 does not move significantly even with a very small rotation angle. Therefore, it is easy to check the movement of moiré in the article 1.

P1 shown in FIG. 3 is the actual pitch of the first pattern elements 210. Further, P1' shown in FIG. 3 is an apparent pitch of the first pattern elements 210 in a direction perpendicular to the height direction D of the article 1. Further, α1 shown in FIG. 3 is the inclination angle of the arrangement of the first pattern elements 210 with respect to the height direction D of the article 1. Hereinafter, the actual pitch of the second pattern elements 220 will be referred to as P2, and the apparent pitch of the second pattern elements 220 will be referred to as P2'.

The apparent pitch P1' of the first pattern element 210 and the apparent pitch P2' of the second pattern element 220 satisfy the relationship shown in the following inequality (1).

It is preferable that the apparent pitches P1' and P2' satisfy the relationship shown in inequality (2) below.

It is more preferable that the apparent pitches P1' and P2' satisfy the relationships shown in the following inequality (3) and equation (4), and it is still more preferable that the apparent pitches satisfy the relationship shown in the following inequality (5).

It is further preferable that the apparent pitches P1' and P2' satisfy the relationship shown in equation (6) below.

In addition, in formulas (1) to (6), n2 is the refractive index of the content 4, D1 is the distance between the first pattern 21 and the second pattern 22, and N is the distance in the height direction of the article 1. D2 is the number of first pattern elements 210 in any cross section perpendicular to the container body 3, and D2 is the distance between the container body 3 and the viewer.

When the content 4 exists between the first pattern 21 and the second pattern 22, moire does not occur, moire becomes unclear, or is actually perceptible due to the refractive index n2 of the content 4. Problems may occur, such as the moire generated is worse than the designed moire. This problem can be solved by making the apparent pitches P1' and P2' satisfy the relationships shown in any one of the above equations (1) to (3) and (5) and (6). be able to. Therefore, if the apparent pitches P1' and P2' satisfy the relationships shown in any one of the above equations (1) to (3), (5) and (6), a high eye-catching effect can be achieved. be able to.

Note that in FIG. 2, the plurality of second pattern elements 220 are not arranged at a constant pitch, and the actual pitch P2 of the second pattern elements 220 varies between one position and another position of the second pattern 22. It's different. That is, the apparent pitch P2' differs between one position and another position of the second pattern 22. In this case, each of the apparent pitch P1' and the apparent pitch P2' satisfy the relationship shown in any one of the above equations (1) to (3), (5) and (6). is preferred.

Below, we will explain in more detail why it is preferable that the apparent pitches P1' and P2' satisfy the relationships shown in any one of the above equations (1) to (3), (5) and (6). explain.

FIG. 4 is a cross-sectional view schematically showing a cross section of the label 2 perpendicular to the height direction of the article 1. In FIG. 4, the container body 3 and contents 4 are not illustrated. Moreover, in FIG. 4, D1 is the distance between the first pattern 21 and the second pattern 22, and D2 is the distance between the container body 3 and the observer 6.

In FIG. 4, the center of the second pattern 22 is located on a straight line passing through the center of the first pattern 21 and the center O of the container body 3. The eyes of the observer 6 are positioned on this straight line so as to observe the second pattern 22 through the first pattern 21. Here, the center O of the container body 3 is assumed to be the intersection of two diagonal lines of the container body 3 in the cross section shown in FIG. Note that in FIG. 4, a line segment L1 indicated by a broken line is a part of the straight line.

As shown in FIG. 4, since the contents 4 are present in the container body 3, the light from the second pattern 22 passes through the interface of the contents 4 before reaching the eyes of the observer 6. refracted by. Therefore, the second pattern 22 appears larger compared to the case where the content 4 is not present. Furthermore, since the distance between the first pattern 21 and the second pattern 22 is large, this magnification cannot be ignored. Therefore, when determining the optimal relationship for the apparent pitches P1' and P2', it is necessary to take this refraction and distance into consideration.

Here, as a simplified model, it is assumed that both the first pattern element 210 and the second pattern element 220 are linear and arranged at a constant pitch in the width direction. Further, it is assumed that the inclination angle of the arrangement of the first pattern elements 210 and the inclination angle of the arrangement of the second pattern elements 220 are equal. Further, when the second pattern is observed through the first pattern 21 and the contents 4, it is assumed that the outline of the second pattern 22 matches the outline of the first pattern 21. Further, in FIG. 4, it is assumed that the number of first patterns 21 and the number of second patterns 22 are equal. It is assumed that under such conditions, the overlapping of the first pattern 21 and the second pattern 22 causes moiré.

A line segment L2 in FIG. 4 is a line segment that passes through the end of the first pattern 21 and is parallel to the line segment L1.
Under the observation conditions shown in FIG. 4, the optical path of the light emitted from the end of the second pattern 22 and reaching the eyes of the observer 6 is shown by a chain line. This light enters the wall of the container body 3 at an incident angle β, and is emitted from the wall of the container body 3 toward the eyes of the observer 6 at a refraction angle α.

Further, as is clear from FIG. 4, the image displayed by the second pattern 22 is enlarged at the position of the first pattern 21 and appears to overlap with the image of the first pattern 21. Hereinafter, the image of the second pattern 22 overlapping at the position of the first pattern 21 will be referred to as a "projected image."

If the number of first pattern elements 210 existing between one end of the first pattern 21 and the line segment L1 is N/2, the dimension from one end of the projected image to the line segment L1 is the product P1'×N/2. be. Furthermore, since the number of second pattern elements 220 existing between one end of the second pattern 22 and the line segment L1 is N/2, the dimension from one end of the second pattern 22 to the line segment L1 is the product P2 '×N/2. This dimension is equal to the sum of the above product P1'×N/2 and the product D1×tanβ of distance D1 and tanβ. Therefore, from these matters, the relationship shown in Equation (7) below can be derived.

Further, the incident angle β and the refraction angle α satisfy the relationship shown in the following equation (8) according to Snell's law.

By transforming the above equation (8), the relationship shown in the following equation (9) is obtained.

Here, by substituting the above equation (7) into the above equation (9), the relationship shown in the following equation (10) is obtained.

Further, as is clear from FIG. 4, tanα is obtained by dividing the above product P1'×N/2 by the distance D2. That is, tanα can be expressed by the following equation (11).

By transforming the above equation (11), the relationship shown in the following equation (12) is obtained.

Here, by substituting the above equation (10) into the above equation (12), the above equation (6) can be derived.

Note that although it is assumed here that moire occurs under the above conditions, it is possible to produce moire that is easy to visually recognize even if the above conditions are slightly changed. For example, when the range shown in equation (3) above is satisfied, moiré that is easy to visually recognize can be produced.

According to an example, the apparent pitch P1' is set to 1, the refractive index n2 is set to be within the range of 1.33 to 1.47, and the distance D1 is set to be within the range of 5 cm to 15 cm. , the distance D2 can be set to be within a range of 30 cm to 50 cm, and the number N can be set to be 80. When such conditions are referred to in the above equation (6), it can be seen that the above inequality (1) or (2) is preferable.

By the way, if the moire displayed by the article 1 moves significantly by slightly changing the viewing direction, the movement of the moire may be perceived as flickering of the image. On the other hand, even if the viewing direction is greatly changed, if the movement of the moire displayed by the article 1 is slight, the movement of the moire itself is difficult to perceive. The magnitude of the change in the viewing direction varies depending on the distance between the observer and the article 1. That is, when the distance between the observer and the article 1 is long, the observation direction does not change significantly. On the other hand, when the distance between the observer and the article 1 is short, the observation direction can change significantly.

For example, when it is assumed that moire is observed while holding the article 1 in hand, the apparent pitch P1' of the first pattern elements 210 is preferably within a range of 0.2 mm to 10 mm; More preferably, it is within the range of 0.2 mm to 5 mm. Further, in this case, the apparent pitch P2' of the second pattern elements 220 is preferably within the range of 0.2 mm to 10 mm, and more preferably within the range of 0.2 mm to 5 mm.

When it is assumed that the moire displayed by the article 1 placed on a shelf or the like is observed from a certain distance, the apparent pitch P1' of the first pattern elements 210 is 0.5 mm to 30 mm. It is preferably within the range of 1 mm to 10 mm, and more preferably within the range of 1 mm to 10 mm. Further, in this case, the apparent pitch P2' of the second pattern elements 220 is preferably within the range of 0.5 mm to 30 mm, and more preferably within the range of 1 mm to 10 mm.

The actual pitch P1 of the first pattern elements 210 is preferably within a range of 0.2 mm to 30 mm, and more preferably within a range of 0.2 mm to 5 mm.

The width or diameter of each of the first pattern elements 210 is preferably within a range of 20% to 80% of the actual pitch P1.

The actual pitch P2 of the second pattern elements 220 is preferably within a range of 0.2 mm to 30 mm, and more preferably within a range of 0.2 mm to 5 mm.

The width or diameter of each second pattern element 220 is preferably within a range of 20% to 80% of the actual pitch P2. This width or diameter may be constant or may vary in the arrangement direction of the second pattern elements 220.

The tilt angle α1 is preferably within the range of 5° to 85°, and more preferably within the range of 40° to 70°.

Further, the inclination angle α2 of the arrangement of the second pattern elements 220 with respect to the height direction D is preferably within the range of 5° to 85°, and more preferably within the range of 40° to 70°. Note that, as described above, the second pattern element 220 may be linear, or may be bent or curved. In the latter case, the arrangement direction of the second pattern elements 220 may be different between a part of the second pattern 22 and another part. In this case, it is preferable that the inclination angle α2 of at least a portion of the second pattern 22 is within the above range.

The distance D1 is preferably within a range of 20 mm to 200 mm, and more preferably within a range of 50 mm to 150 mm.

The ratio P1'/D1 of the apparent pitch P1' to the distance D1 is preferably within the range of 0.001 to 0.5, more preferably within the range of 0.001 to 0.25. When the ratio P1'/D1 is within the above range, moiré movements are particularly easy to see.

Further, the ratio P2'/D1 of the apparent pitch P2' to the distance D1 is preferably within the range of 0.001 to 0.5, more preferably within the range of 0.001 to 0.25. preferable. When the ratio P2'/D1 is within the above range, moiré movements are particularly easy to see.

Note that, depending on the above-mentioned observation direction, the observer can observe continuous or discrete changes in the color, pattern, or shading of the moiré.

In the above-mentioned article 1, the apparent pitch P1' of the first pattern element 210, the apparent pitch P2' of the second pattern element 220, and the refractive index n2 of the content 4 satisfy the above-mentioned formula (1) to Either one of (3) and (5) is satisfied. Therefore, the above-mentioned problems such as no moiré, which may occur when the content 4 is present between the first pattern 21 and the second pattern 22, are less likely to occur. Therefore, the article 1 described above tends to catch the eye of the observer. That is, a high eye-catching effect can be achieved.

Moreover, the above-mentioned article 1 includes a body having a pair of walls facing each other in parallel, and has a first pattern 21 on one wall and a second pattern 22 on the other wall. In such an article 1, since the distance between the first pattern 21 and the second pattern 22 is large, it is easy to perceive the movement of moire in response to a change in the viewing direction. Therefore, the article 1 described above has a high eye-catching effect in this respect as well.

Furthermore, in the article 1 described above, at least one of the arrays of the first pattern elements 210 and the second pattern elements 220 is inclined with respect to the height direction of the article 1. Therefore, the movement of the moire can be perceived without changing the viewing direction excessively, and flicker caused by a large movement of the moire can not be perceived even with a slight change in the viewing direction. Therefore, it is easy to check the movement of moire.

Note that in the article 1 described above, the first pattern 21 and the second pattern 22 are provided on one label, but the first pattern 21 and the second pattern 22 may be provided on separate labels. . Alternatively, at least one of the first pattern 21 and the second pattern 22 may be provided on the container body 3.
