Summary of the Invention

Problems to be Solved by the Invention

[0004] When a label is not attached to the bottle container, it will have the appearance of a mere transparent container with light - transmissivity, and it will not be possible to ensure the designability by patterns, photographs, characters, etc. that can be displayed on the label.

[0005] Therefore, it becomes difficult to appeal to the consumer's vision from the appearance of the container. For example, when displayed side - by - side with other products, it is difficult to differentiate from other products, and it is also difficult to make the consumer recognize the brand.

[0006] Therefore, when selling in a label - less form, it is an issue to be able to differentiate from other products by demonstrating designability, improve the appeal to consumers, and further enable brand recognition.

[0007] In view of the above problems, this invention proposes a novel technology for selling products in plastic bottle containers in a "label-free" form. [Means for solving the problem]

[0008] The problems that this invention aims to solve are as described above, and the means for solving these problems will now be explained.

[0009] According to one aspect of the present invention, a translucent container is provided, comprising at least a first region that allows the liquid inside to be seen, and a second region that allows the liquid to be seen with a light transmittance different from that of the first region.

[0010] Furthermore, according to one aspect of the present invention, the container has a cylindrical body, a mouth at one end of the body, and a bottom at the other end of the body, and the circumferential surface of the body has at least a first columnar portion extending in the direction of the cylindrical axis of the body, and a second columnar portion extending in the direction of the cylindrical axis of the body at a position circumferentially offset from the first columnar portion, and the first region and the second region are formed by the irregularities formed by the first columnar portion and the second columnar portion.

[0011] Furthermore, according to one aspect of the present invention, the first columnar portion is a pair arranged in positions opposite to each other, the second columnar portion is a pair arranged in positions opposite to each other, the second columnar portion appears on both sides of the first columnar portion in a side view, and the first columnar portion appears on both sides of the second columnar portion, the liquid in the regions on both sides of the first columnar portion appears brighter than the liquid in the region of the first columnar portion when viewed from the front in a side view, and the liquid in the regions on both sides of the second columnar portion appears brighter than the liquid in the region of the second columnar portion when viewed from the front in a side view.

[0012] Furthermore, according to one aspect of the present invention, the length in the axial direction of the first columnar portion and the length in the axial direction of the second columnar portion are the same, and the circumferential width of the first columnar portion and the circumferential width of the second columnar portion are different.

[0013] Furthermore, according to one aspect of the present invention, a decorative portion is formed in the body portion in an area that does not overlap with the first columnar portion and the second columnar portion.

[0014] Furthermore, according to one aspect of the present invention, in the body portion, the region that does not overlap with the first columnar portion and the second columnar portion is reduced in diameter so that the diameter of the body gradually decreases toward the central portion in the direction of the cylindrical axis of the body portion.

[0015] Furthermore, according to one aspect of the present invention, the container is for which a colored beverage is filled and for use without a label. [Effects of the Invention]

[0016] The present invention provides the following effects: In other words, according to one aspect of the present invention, even when a product is sold in a label-less form without a label affixed to the bottle container, it is possible to ensure design appeal through contrast, making it possible to appeal to consumers' visual senses from its appearance. This makes it possible to differentiate the product from other products and to make consumers recognize the brand. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0018] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the invention according to the claims, and not all combinations of the features described in the embodiments are essential to the invention. Two or more of the plurality of features described in the embodiments may be arbitrarily combined. Also, the same or similar configurations are given the same reference numerals, and redundant descriptions are omitted.

[0019] In FIGS. 1(A)(B) and FIG. 2, the appearance of a bottle container 1 according to an embodiment is exemplarily shown. FIG. 3(A) shows a cross-sectional end view of the bottle container 1 along line B-B and line C-C of FIG. 1(A), and FIG. 3(B) shows a cross-sectional end view of the bottle container 1 along line A-A of FIG. 1(A).

[0020] As shown in FIGS. 1(A)(B) and FIG. 2, the bottle container 1 is configured to have a mouth part 10, a shoulder part 20 extending from the mouth part 10, a bottom part 40, and a body part 30 connecting the shoulder part 20 and the bottom part 40. The capacity of the bottle container 1 is not particularly limited, but for example, it is 180 ml (milliliter, the same hereinafter), 350 ml, 500 ml, 600 ml, etc.

[0021] The lowermost end of the mouth part 10 is configured in a cylindrical shape. The shoulder part 20 has a substantially circular cross-section and is connected to the body part 30 with the diameter gradually increasing toward the body part 30. The body part 30 is configured in a cylindrical shape, and its lower end is connected to the bottom part 40.

[0022] After the beverage is filled into the bottle container 1, a cap (not shown) is attached to the mouth 10 to seal it. The beverage is not limited to, for example, tea (e.g., unfermented tea, semi-fermented tea, fermented tea), water, soft drinks, fruit juices, etc. The color of the beverage is also not particularly limited, but as will be described in detail later, a colored and translucent material may be preferably selected to express the shades (contrasts) of the beverage's color. Note that Figure 2 shows the bottle container in grayscale, but this is for reference only, and in reality, it is implemented using a colorless, colored, transparent, or translucent plastic container, and is constructed as a so-called transparent PET bottle container.

[0023] Figure 1(A) is a front view of the bottle container 1 viewed from a first direction Y, and a first columnar portion 31 is formed on the body portion 30, extending in the direction of the cylindrical axis CL of the bottle container 1. The center line of the column width of the first columnar portion 31 coincides with the cylindrical axis CL.

[0024] As shown in Figures 1(A) and 1(B), connecting portions 33, 33 appear on both sides of the first columnar portion 31, and the second columnar portion 32 appears further outside the connecting portions 33, 33.

[0025] Figure 1(B) is a side view of the bottle container 1 viewed from a second direction X, where a second columnar portion 32 is formed on the body portion 30, extending in the direction of the cylindrical axis CL of the bottle container 1. The center line of the column width of the second columnar portion 32 coincides with the cylindrical axis CL.

[0026] As shown in Figures 1(A) and 1(B), connecting portions 33, 33 appear on both sides of the second columnar portion 32, and the first columnar portion 31 appears further outside the connecting portions 33, 33.

[0027] The cross-section end view in Figure 3(A) (the cross-section along line BB and line CC in Figure 1(A)) shows the end face when the body portion 30 is cut by a plane perpendicular to the cylindrical axis CL (central axis). Figure 3(A) shows the end face in mutually perpendicular XY axis coordinate planes, and shows a pair of first columnar portions 31, 31 positioned opposite each other in the Y-axis direction, a pair of second columnar portions 32, 32 positioned opposite each other in the X-axis direction, and connecting portions 33, 33 connecting adjacent columnar portions 31, 32.

[0028] Similarly, the cross-section end view in Figure 3(B) (the cross-section along line AA in Figure 1(A)) shows the end face when the body portion 30 is cut by a plane perpendicular to the cylindrical axis CL (central axis). Similarly, Figure 3(B) shows the end face in mutually perpendicular XY axis coordinate planes, and shows a pair of first columnar portions 31, 31 positioned opposite each other in the Y-axis direction, a pair of second columnar portions 32, 32 positioned opposite each other in the X-axis direction, and connecting portions 33, 33 connecting adjacent columnar portions 31, 32.

[0029] As shown in Figures 3(A) and 3(B), each connection portion 33 has a stepped recessed portion 33a formed thereon. The shading and edges of this recessed portion 33a create a vertical decorative line 33b when the bottle container is viewed from the side, as shown in Figures 1(A) and 1(B). The recessed portion 33a may be provided over the entire range of the connection portion 33, over a portion of the range, or at multiple locations on the side closer to the first columnar portion 31, as shown in Figures 3(A) and 3(B). In this embodiment, relatively small stepped recessed portions of 3 steps (Figure 3(A)) or 4 steps (Figure 3(B)) are formed on both sides of the first columnar portion 31 in the X direction, and a relatively large stepped recessed portion of 1 step is formed on both sides of the second columnar portion 32 in the Y direction, at the rising portion of the second columnar portion 32. In addition, the recessed portions may have the same form at all four connection portions 33, or they may have different forms at each connection portion.

[0030] As shown in Figures 3(A) and 3(B), each columnar portion 31 and 32 is formed to protrude radially outward from the inscribed circle S centered on the cylindrical axis CL, and the shape of the columnar portion can be defined by the dimensions in the protruding direction as the column heights 31a and 32a. For example, the column height 31a is 5.5 mm to 7.5 mm (millimeters, the same applies hereinafter), and the column height 32a is 5.0 mm to 7.0 mm, more preferably 5.5 mm to 6.5 mm. A specific example is that the column height 31a is 6.5 mm and the column height 32a is 6.0 mm.

[0031] Similarly, the shape of each columnar portion 31, 32 can be defined by defining the column widths 31b and 32b as the dimensions in the direction perpendicular to the protruding direction in the horizontal plane. For example, the column width 31b may be 25 mm to 27 mm, and the column width 32b may be 15 mm to 17 mm, preferably 26 mm for column width 31b and 16 mm for column width 32b.

[0032] Similarly, in Figure 4, the shape of the columnar parts can be defined by defining the diameter 31d of the circumscribed circle along the outer circumferential surface of the pair of columnar parts 31, 31, and the diameter 32d of the circumscribed circle along the outer circumferential surface of the pair of columnar parts 32, 32. For example, the diameter 31d is 54 mm to 56 mm, and the diameter 32d is 53 mm to 55 mm, preferably the diameter 31d is 55 mm and the diameter 32d is 54 mm.

[0033] In Figures 3(A) and 3(B), the distance between the first columnar parts 31, 31 and their outer surfaces, with the cylindrical axis CL in between, is defined as the first columnar distance 31c. Similarly, the distance between the second columnar parts 32, 32 and their outer surfaces, with the cylindrical axis CL in between, is defined as the second columnar distance 32c. The inscribed circle S has a diameter of 30s, which is, for example, 42 mm. The inscribed circle S is a hypothetical perfect circle, and the columnar parts 31, 32 and the connecting part 33 are arranged outside the inscribed circle S along the circumferential direction.

[0034] The outer contour line TA of the cut end face shown in Figure 3(A) corresponds to the upper and lower cut points of the body portion 30 (the cut surfaces along lines BB and CC in Figure 1(A)), and the outer contour line TB of the cut end face shown in Figure 3(B) corresponds to the central part of the body portion 30 in the vertical direction (the cut surface along line AA in Figure 1(A)). Figure 4 is a schematic diagram of Figures 3(A) and (B) superimposed, and the minimum diameter 30sA (diameter of the inscribed circle S) of the outer contour line TA is assumed to be larger than the minimum diameter 30sB (diameter of the inscribed circle S) of the outer contour line TB.

[0035] Furthermore, in the comparison of Figures 3(A) and 3(B), the column heights 31a and 32a of the columnar parts 31 and 32 of the outer contour line TA are assumed to be smaller than the column heights 31a and 32a of the columnar parts 31 and 32 of the outer contour line TB.

[0036] As a result, as shown in Figures 1(A) and 1(B), the columnar portions 31 and 32 appear to protrude significantly to the left and right from the cylindrical axis CL near the center Cf in the vertical direction, while the protrusion of the columnar portions 31 and 32 from the cylindrical axis CL appears smaller near the upper end Ct and lower end Cd.

[0037] Furthermore, as shown in Figures 3(A) and 3(B), the heights 31t and 32t of each columnar section 31 and 32 from the cylindrical axis CL are higher near the upper end Ct and lower end Cd than the height near the center Cf in the vertical direction.

[0038] As a result, as shown in Figures 1(A) and 1(B), a gentle arc is formed in the center of the body portion 30 in the direction of the cylindrical axis CL, such that the ridges 31r and 32r of the columnar portions 31 and 32 are constricted inward.

[0039] Furthermore, as shown in Figures 3(A) and 3(B), the diameter 30s of the inscribed circle S of the outer contour line is designed to continuously decrease in diameter from near the upper end Ct (Figure 1(A)) and near the lower end Cd (Figure 1(A)) of the body portion 30 toward the central area Cf (Figure 1(A)).

[0040] As a result of the above configuration, as shown in Figures 1(A) and 1(B), the outer diameter of the body 30 gradually decreases from the upper end Ct and the lower end Cd towards the center Cf, giving it a roughly drum-like appearance. Consequently, sloping sides 33k, 33k appear in the body 30 from the upper part towards the center and from the center towards the lower part, where the outer diameter continuously decreases.

[0041] Furthermore, as shown in Figure 1(A), multiple decorative lines 33b appear on the wall surfaces 33h2 of the connecting portions 33, 33 that appear on both sides of the first columnar portion 31, in the vertical direction (the direction in which the cylindrical axis CL extends), and the length of the decorative lines 33b is formed to decrease as it moves away from the cylindrical axis CL.

[0042] Furthermore, as shown in Figure 1(B), multiple decorative lines 33b appear on the wall surfaces 33h1 of the connecting portions 33, 33 that appear on both sides of the second columnar portion 32, in the vertical direction (the direction in which the cylindrical axis CL extends), and the length of the decorative lines 33b is formed to increase as they move away from the cylindrical axis CL.

[0043] Furthermore, as shown in Figure 1(A), the side wall surfaces 32s of the second columnar portion 32 appear further outward than the decorative lines 33b on both sides of the first columnar portion 31. The thickness of the second columnar portion 32, that is, the distance 32D (thickness) between the side wall surfaces 32s in the first direction Y in Figure 3(A), is smaller (thinner) than the distance (thickness) between the front wall surfaces 31m of the pair of first columnar portions 31 in the same direction (first column distance 31c).

[0044] Furthermore, as shown in Figure 1(B), the connecting portions 33 on both sides of the second columnar portion 32 are also the side wall surfaces 31s of the first columnar portion 31. The thickness of the first columnar portion 31, that is, the distance 31D (thickness) between the side wall surfaces 31s in the second direction X in Figure 3(A), is smaller (thinner) than the distance (thickness) between the front wall surfaces 32m of the pair of second columnar portions 32 in the same direction (distance between second columns 32c).

[0045] As described above, as shown in Figures 5(A) and 6(A), when a colored beverage (for example, barley tea) is filled into a bottle container, when the first columnar portion 31 is viewed from the front (in the direction of arrow Y1 (Figure 6(A))), the first region 31R1 including the first columnar portion 31 appears dark (dark brown), while the second regions 31R2 on both sides of the first columnar portion 31 appear bright (light brown), creating a contrast. This is because the region of the first columnar portion 31 appears dark because it is thick in the depth direction (in the direction of the line of sight (arrow Y1 (Figure 6(A))), making it difficult for light to pass through (low transmittance), while the regions on both sides of the first columnar portion 31 appear bright because they are thin in the depth direction and easily transmit light.

[0046] Similarly, as shown in Figures 5(B) and 6(B), when the second columnar portion 32 is viewed from the front (in the direction of arrow Y1 (Figure 6(A))), the first region 32R1 including the second columnar portion 32 appears dark (dark brown), while the second regions 32R2 on both sides of the second columnar portion 32 appear bright (light brown), creating a contrast. This is because the region of the second columnar portion 32 appears dark because it is thick in the depth direction (in the direction of the line of sight (arrow Y1 (Figure 6(B))), making it difficult for light to pass through (low transmittance), while the regions on both sides of the second columnar portion 32 appear bright because they are thin in the depth direction and easily transmit light.

[0047] Furthermore, as shown in Figure 5(A), the refraction of light due to the unevenness of the decorative line 33b creates a long, linear shadow along the decorative line 33b. Also, as shown in Figure 5(A), the refraction of light due to the unevenness of the decorative line 33b creates a linear shadow along the decorative line 33b, as well as short, jagged shadows at the top and bottom ends of the linear shadow.

[0048] The present invention can be implemented in the manner described above. That is, as shown in Figures 5(A) and 5(B), the bottle container 1 is translucent, The container has at least a first region in which the liquid inside is visible, and a second region in which the liquid is visible with a different light transmittance than that of the first region.

[0049] Specifically, as shown in Figures 1(A) and 1(B), the bottle container 1 has a cylindrical body 30, a mouth 10 at one end of the body 30, and a bottom 40 at the other end of the body 30. The circumferential surface of the body 30 has at least a first columnar portion 31 extending in the direction of the cylindrical axis CL of the body 30, and a second columnar portion 32 extending in the direction of the cylindrical axis CL of the body 30 at a position circumferentially offset from the first columnar portion 31. The irregularities formed by the first columnar portion 31 and the second columnar portion 32 form a first region and a second region.

[0050] Furthermore, the first columnar parts 31 are arranged in pairs so as to be opposite each other, and the second columnar parts 32 are arranged in pairs so as to be opposite each other, so that in a side view the second columnar parts 32 appear on both sides of the first columnar parts 31 and the first columnar parts 31 appear on both sides of the second columnar parts 32, so that when the first columnar parts 31 are viewed from the front in a side view the liquid in the areas on both sides of the first columnar parts 31 appears brighter than the liquid in the area of ​​the first columnar parts 31, and when the second columnar parts 32 are viewed from the front in a side view the liquid in the areas on both sides of the second columnar parts 32 appears brighter than the liquid in the area of ​​the second columnar parts 32.

[0051] Furthermore, the pair of first columnar parts 31 and second columnar parts 32 may be positioned at an angle of 90° from each other in a plan view, or at other angles. In addition, the number of first columnar parts 31 and second columnar parts 32 may be 2 each, 3 each, 4 each, etc., or the number of each may be different. Moreover, while the contrast is formed by the difference in brightness between the first and second regions due to the first columnar parts 31 and second columnar parts 32, a third region, a fourth region, etc., which form contrasts with different brightness levels may also be formed.

[0052] Furthermore, as shown in Figures 3(A) and 3(B), the length of the first columnar portion 31 in the direction of the cylindrical axis CL is the same as the length of the second columnar portion 32 in the direction of the cylindrical axis CL, while the circumferential width of the first columnar portion 31 (column width 31b) and the circumferential width of the second columnar portion 32 (column width 32b) are different.

[0053] In this embodiment, the column width 31b of the first columnar portion 31 is set to be wider than the column width 32b of the second columnar portion 32, thereby ensuring the desired strength (rigidity). Even when the beverage filled inside is depressurized, the inscribed circle S does not deform and collapse into an ellipse shape, and the inscribed circle S can maintain a nearly perfect circle shape.

[0054] Furthermore, as a configuration that further suppresses deformation, the ratio of the column width 32b of the second columnar portion 32 to the column width 31b of the first columnar portion 31 (column width 32b / column width 31b) is preferably 0.45 or more, more preferably 0.5 or more, and even more preferably 0.55 or more.

[0055] Furthermore, to enhance the contrast, the ratio of the column width 32b of the second columnar part 32 to the column width 31b of the first columnar part 31 (column width 32b / column width 31b) is preferably 0.85 or less, more preferably 0.75 or less, and even more preferably 0.70 or less.

[0056] Furthermore, in the body portion 30, multiple decorative parts, such as decorative lines 33b consisting of linear irregularities extending in the direction of the cylindrical axis CL, are formed in areas that do not overlap with the first columnar portion 31 and the second columnar portion 32. In addition to linear irregularities, for example, irregularities forming geometric patterns may also be used, and furthermore, in addition to these irregularities, decorative irregularities may be formed on the first columnar portion 31 and the second columnar portion 32.

[0057] Furthermore, in the body portion 30, the region that does not overlap with the first columnar portion 31 and the second columnar portion 32 is designed to gradually decrease in diameter toward the central portion of the body portion 30 in the direction of the cylindrical axis CL.

[0058] Based on the above, even when products are sold in a label-less form without labels on the bottle container, design appeal can be ensured through contrast, making it possible to appeal to consumers visually through appearance. This allows for differentiation from other products and makes it possible to make the brand known to consumers.

[0059] In the above embodiment, the bottle container may be sold with a label attached. For example, by attaching the label to the shoulder, the label can perform its function while the body can display a distinctive design with contrast. [Explanation of Symbols]
