Description

display tools

[0001] The present invention relates to a display device for displaying an object. The present invention claims priority to Japanese Patent Application No. 2023-216682 filed on December 22, 2023, Japanese Patent Application No. 2024-066711 filed on April 17, 2024, and Japanese Patent Application No. 2024-166117 filed on September 25, 2024, and the contents of those applications are incorporated by reference into this application in designated states where incorporation by reference of documents is permitted.

[0002] Objects, such as items contained in bottles or jars (hereinafter collectively referred to as "bottles"), are usually marked on the outer surface of the body of the bottle, making it difficult to identify what is contained therein from above.

[0003] For this reason, in the past, for example, a "capped sample bottle characterized by having a content display means that allows the contents of the sample to be seen from above" has been proposed, and it has been proposed that "the content display means is a sheet-like member that is affixed to the top surface of the cap and on which a content display is written" (see claims 1 and 2 of Patent Document 1).

[0004] Japanese Patent Application Laid-Open No. 2002-128085

[0005] The above-mentioned sample bottle has the effect that "even if the capped sample bottle is stored in a drawer or on a shelf with only the top side of the cap visible in order to save storage space, the contents display means can be seen while the sample bottle is displayed, so the contents of the sample bottle can be identified without having to remove it each time" (see paragraph

[0010] of Patent Document 1).

[0006] On the other hand, the sample bottle uses a sheet-like member such as a paper or synthetic paper label that can be attached to the top surface of the cap as the content display means, and since the sheet-like member is smaller than the top surface of the cap, if the cap itself is small, the sheet-like member such as a paper or synthetic paper label becomes even smaller, reducing its identifiability.Furthermore, such sheet-like member such as a paper or synthetic paper label cannot be reused.

[0007] The present invention is intended to solve at least one of the above problems, and has an object to provide a display device that is more easily distinguishable and easier to use.

[0008] One aspect of the present invention that solves the above-mentioned problems is a display device that is attached to the target surface of an object to display the object, and includes a top plate that is wider than the target surface of the object, a peripheral wall that extends cylindrically downward from the edge of the underside of the top plate, and an adhesive portion provided below the top plate and inside the peripheral wall.

[0009] The peripheral wall may be configured so that its height is greater than the thickness of the adhesive portion.

[0010] The adhesive portion may have a lower surface that is an upwardly concave arcuate surface.

[0011] The top plate may have a lower surface that is an upwardly concave arcuate surface.

[0012] The top plate may have an upper surface that is an upwardly convex arc surface.

[0013] The top plate may have a lower surface that is an arcuate surface that is concave upward, and may include a spacer that has a convex upper surface between the lower surface of the top plate and the adhesive portion.

[0014] The top plate may have a protrusion extending upward from the edge of the top surface.

[0015] A movable plate may be provided on the top surface of the tabletop so that the display angle can be changed.

[0016] The peripheral wall may have a notched escape portion at a part of the lower end.

[0017] The display device may include at least one of a first indicia representing the object and a second indicia indicating the orientation of a cap of a container that contains the object.

[0018] The top plate may have an adjustment hole for adjusting the degree of contact with the target surface of the target object.

[0019] According to the present invention, it is possible to provide a displaying device that is more easily distinguishable and easier to use.

[0020] Problems, configurations, and effects other than those described above will become apparent from the following description of the embodiments.

[0022] Hereinafter, examples of embodiments of the present invention will be described with reference to the drawings. Note that components common to the following embodiments and their modifications will be designated by the same reference numerals as those mentioned above, and their description may be omitted. Furthermore, when referring to the shape, positional relationship, etc. of components, etc., this includes those that are substantially similar or similar to the shape, etc., unless otherwise specified or when it is clearly considered otherwise in principle.

[0023] The objects for which the display device according to the present invention is used are typically items contained in containers such as bottles, such as food and beverages such as seasonings, alcoholic beverages, and jam. Here, seasonings include traditional items such as soy sauce, mirin, cooking sake, vinegar, miso, and salt, as well as cooking oils, dressings, sauces, and herbs. The objects may also be items other than food and beverages. The objects may be items that are poured or scooped from the container, or may be items that are sprayed using a structure provided on the container.

[0024] The display device according to the present invention is particularly suitable for bottle-shaped containers. Bottle-shaped containers include not only the above-mentioned bottle-shaped containers for storing food and beverages, but also, for example, spray cans. The material of such containers is not particularly limited, and they may be made partly or entirely of resin, or partly or entirely of ceramic, glass, metal, etc. Such containers have a body as described below and may include a structure suitable for their intended use together with or in place of a cap.

[0025] The target surface of the object to which the display device is attached is the surface of a predetermined part of the container in which the object is stored, and more specifically, is determined by the orientation of the container during use or storage of the object. For example, the target surface of a bottled item is determined by the orientation of the bottle during use or storage.

[0026] <Embodiment 1> Figures 1 and 2 are diagrams for explaining a display device of embodiment 1, where Figure 1(a) is a plan view, Figure 1(b) is a cross-sectional view taken along line AA of Figure 1(a), Figure 2(a) is a front view, Figure 2(b) is a bottom view, Figure 2(c) is a cross-sectional view taken along line AA of another example, and Figure 2(d) is a cross-sectional view taken along line AA of yet another example. Figure 3 is a diagram for explaining the display device of embodiment 1, where (a) is a diagram showing an example of use and (b) is a front view of another example. Figure 4 is a diagram showing an example of use of the display device of embodiment 1. Figures 5 and 6 are diagrams for explaining the display device of embodiment 1, where Figure 5 is a partial enlarged view of Figure 1(b), and Figure 6 is a diagram showing another example of a usage state. In each diagram, X indicates the left-right direction (horizontal direction), Y indicates the up-down direction (vertical direction), and Z indicates the front-back direction (depth direction) (the same applies to each diagram below). The line AA coincides with the center line extending in the Z direction that passes through the center of the display device, and unless otherwise specified below, the cross-sectional views will be taken as cross-sectional views along the line AA. In this application, the direction approaching the center line extending in the Y direction of the display device is defined as the inward (inside).

[0027] As shown in Fig. 3(a), the object O in this embodiment is, for example, a bottled item contained in a bottle B. The object O shown in the figure is, for example, a bottled food or drink, such as soy sauce seasoning. The bottle B has an outlet at the top of the body and a cap C at the top end for opening and closing the outlet. The bottle B usually has a product label (labeled by the manufacturer or seller of the object O) (not shown) on the outer circumferential surface of the body.

[0028] The display device 1 is attached to the target surface of the object O to display such an object O. Bottled soy sauce is placed in an upright position with the cap C facing upward, such as in a drawer or case (box, basket) installed below a countertop. Such drawers or cases have side walls, making it difficult to identify the product label on the outer periphery of the body of the bottle B. In this upright position, the target surface of the object O to which the display device 1 is attached is the upper surface of the cap C. While the display device 1 can also be used with caps C having a screw structure (screw type), the following description will be given taking as an example a cap C having a hinge structure (hinge type), which is commonly found on condiments and the like. A hinge-type cap C typically has a hinge C1 and a claw C2 on the opposite side of the hinge C1.

[0029] As shown in Figure 1, the display device 1 comprises a top plate 2 that is circular in plan view and wider than the target surface of the target object O, a peripheral wall 3 that extends cylindrically downward from the edge of the underside of the top plate 2, and an adhesive portion 4 that is provided below the top plate 2 and inside the peripheral wall 3.

[0030] More specifically, the display device 1 has a top plate 2 that is circular in plan view and has a diameter D that is larger than the front-to-back width and left-to-right width (or diameter if the top surface is circular) of the top surface of the cap C. As shown in Figure 1(b) , the display device 1 has a gap G between the inner surface of the peripheral wall 3 and the outer surface of the cap C.

[0031] The display device 1 thus has a top plate 2 that is wider than the target surface of the object O, so that even if the cap C is small, the upper surface 21 of the top plate 2, which serves as the display surface, can be configured large to improve the distinguishability of the display. Furthermore, by configuring it in this way, fewer types of display devices 1 can be used to accommodate a variety of caps C of different sizes.

[0032] The indicia 10 displayed on the upper surface 21 may be a name, an abbreviation, a symbol, or the like representing the object. When the indicia 10 is composed of a name or an abbreviation, it may be written in kanji, hiragana, katakana, or the alphabet. The indicia 10 may be black, red, or another color. The indicia 10 may be a combination of multiple colors.

[0033] For example, the indicia 10 is printed directly on the upper surface 21. For example, the indicia 10 is displayed as if a thin film-like substance is attached to the upper surface 21, or as if thin sheets are laminated on the upper surface 21.

[0034] When the display 10 is made up of multiple characters, they may be displayed in uniform size, but preferably, one or more characters are displayed larger than the others to improve distinguishability. For example, for "mirin," "mi" is displayed larger and "rin" is displayed smaller, and for "kurozu," "kuro" is displayed larger and "su" is displayed smaller. In the illustrated example, the name of the object O, "soy sauce," is displayed in kanji, with "shoyu" displayed larger and "abura" displayed smaller.

[0035] The display 10 is preferably displayed in a direction that indicates the orientation of the cap C. The orientation of the cap C is, for example, the position of the operating unit or the direction of the operating motion. For example, in the case of a hinge-type cap C, the display 10 can indicate the installation side of the hook C2. In the illustrated example, the display 10 is displayed so that the bottom side of the characters coincides with the installation side of the hook C2 and the top side of the characters coincides with the installation side of the hinge C1. As a result, if the object O is placed along the direction of the display 10, the removed object O can be opened without having to be re-held, eliminating the need to re-hold the object O.

[0036] As an example, the indicia 10 is displayed so as to be distinguishable visually. As an example, the indicia 10 is displayed so as to be distinguishable by touch, such as in Braille. The indicia 10 may be displayed so as to be distinguishable both visually and tactilely. Commercially available seasonings and the like do not usually have tactile indications, such as in Braille, so by configuring them in this way, even users who rely on their sense of touch can easily distinguish them.

[0037] Condiments and other items are often stored in the same location below eye level, such as in a drawer or case (box, basket) under the counter. The product label on the outer periphery of the container is often obscured by the sidewalls of the drawer or case, as well as surrounding objects, making it difficult to immediately identify and remove the desired item. This problem is not limited to the use of condiments in the kitchen, but can also occur in other places where other objects are used. The display device 1, with its above-described configuration, is highly distinguishable from above, allowing the desired item to be easily identified and removed. Furthermore, the display 10 indicates the orientation of the cap C, allowing the cap C to be opened quickly.

[0038] While the illustrated display device 1 is an example in which the display 10 is already marked by the manufacturer, the display 10 may be marked by the user upon purchase. Because the type of object O used and the location of the object O may vary depending on the user, this configuration allows for greater flexibility. For example, some users may use multiple types of soy sauce, such as light soy sauce and dark soy sauce. This configuration allows for greater flexibility, such as displaying the display 10 as "light" or "strong" instead of "soy sauce." Furthermore, some users may open the container with the claw C2 facing left or right, rather than toward the user. This configuration allows for the user to decide the orientation of the display 10. For example, the display 10 may be handwritten by the user. The display 10 may be configured as a label formed separately from the main body, including the top panel 2, peripheral wall 3, and adhesive portion 4, and provided to the user along with the main body.

[0039] 1(b), the peripheral wall 3 extends cylindrically downward from the edge of the lower surface 22 of the top plate 2, and has a height H (degree of protrusion from the lower surface 22). The peripheral wall 3 is preferably configured so that its lower end surface 31 is located above (higher than) the hinge C1 of the cap C. In some cases, the gap G is smaller than the width of the hinge C1, and if the lower end surface 31 of the peripheral wall 3 were located at the same position as or below the hinge C1, interference with the hinge C1 would occur; this can be avoided by configuring it in this way.

[0040] The bottom end surface 31 of the peripheral wall 3 is located at a position equal to or higher than the claw C2 of the cap C. In other words, the distance from the bottom end surface 31 of the peripheral wall 3 to the top surface 21 of the top plate 2 is equal to or shorter than the distance from the bottom end of the claw C2 to the top surface 21. If the bottom end surface 31 of the peripheral wall 3 were located below the claw C2, the peripheral wall 3 would get in the way when hooking a finger on the claw C2 to open the lid, but this can be avoided by configuring it in this way.

[0041] The peripheral wall 3 may be formed separately from the top plate 2 and joined to it, but is preferably formed integrally with the top plate 2. The top plate 2 and the peripheral wall 3 have at least a rigidity sufficient to maintain their shape when attached to the object O, and more preferably a rigidity sufficient to withstand a finger being placed on them when opening or closing the cap C.

[0042] The materials used for the table top 2 and the peripheral wall 3 are not particularly limited as long as they satisfy the above-described requirements. As an example, the table top 2 and the peripheral wall 3 may be made of plastic resin, metal, wood, etc. One or both of the table top 2 and the peripheral wall 3 may have a color. The table top 2 and the peripheral wall 3 may have the same color or different colors. This allows the display device 1 to be identified not only by the indicia 10 but also by the color of one or both of the table top 2 and the peripheral wall 3.

[0043] 1(b), for example, the adhesive portion 4 is provided on the underside 22 of the top plate 2, and is located inside the peripheral wall 3. The adhesive portion 4 has adhesive force on both the upper and lower surfaces. For example, the upper and lower surfaces of the adhesive portion 4 are configured to be flat surfaces (planes) similar to the underside 22 of the top plate 2.

[0044] As an example, the adhesive portion 4 is configured so that there is almost no gap between it and the inner circumferential surface of the peripheral wall 3, as shown in Fig. 1(b). As an example, the adhesive portion 4 may be configured so that there is a gap between it and the inner circumferential surface of the peripheral wall 3, as shown in Fig. 2(c).

[0045] 2(d), the adhesive portion 4 is configured such that the edge is bent downward to form a corner with a rounded or chamfered cross section. The cap C may have a rounded or chamfered outer periphery, and configuring the adhesive portion 4 in this manner can improve adhesion to the cap C.

[0046] The adhesive portion 4 may be made of any material, for example, reusable adhesive tape. By configuring the adhesive portion 4 in this manner, when the condiment such as soy sauce contained in the bottle runs out, the display device 1 can be removed and attached to another bottle of soy sauce for repeated use.

[0047] The adhesive portion 4 is thinner than the height H of the peripheral wall 3. In other words, the height H of the peripheral wall 3 is greater than the thickness of the adhesive portion 4, and the lower surface of the adhesive portion 4 is located higher than the lower end surface 31 of the peripheral wall 3. By surrounding the adhesive portion 4 with the peripheral wall 3 in this way, the display device 1 can reduce the adhesion and intrusion of dust. In addition, the peripheral wall 3 acts as a stopper, making it less likely to slip sideways.

[0048] As shown in Figure 3(a), the display device 1 is preferably configured so that its diameter D is smaller than the maximum diameter I of the bottle B. By configuring the display device 1 so that its planar area is within the range of the planar area of ​​the bottle B, interference with surrounding objects can be reduced.

[0049] As shown in Figure 3(b), the display device 1 may further have indicia 11 on its outer peripheral surface. The outer peripheral surface of the display device 1 is composed of the outer peripheral surface of the top panel 2 and the outer peripheral surface of the peripheral wall 3. The dashed lines in Figure 3(b) indicate the underside 22 of the top panel 2 and the inner peripheral surface of the peripheral wall 3 in a cross section taken perpendicular to the line AA; in other words, they indicate the thicknesses of the top panel 2 and the peripheral wall 3. In order to display the indicia 11 at a size that allows it to be distinguished, the thickness K of the top panel 2 may be greater than in the above example.

[0050] The marking 11 can be configured by the same means as the marking 10, and a detailed description thereof will be omitted here. The marking 11 may be the same as the marking 10 on the upper surface 21 of the top plate 2, or may be simpler. In the illustrated example, the marking 11 is "shoyu", an abbreviation of "soy sauce". The marking 11 may be one or more marks on a portion of the outer peripheral surface, or may be repeatedly displayed at predetermined intervals around the entire outer peripheral surface as illustrated. The display device 1 can be provided with a further marking 11 in addition to the marking 10, thereby further improving distinguishability.

[0051] As shown in Figure 4, the target surface of the object O to which the display device 1 is attached may be the bottom surface of the body of a bottle B. In this case, the display device 1 is configured so that the inner diameter of the peripheral wall 3 is larger than the maximum diameter I of the bottle B. If the object O is, for example, a bottle of wine, it may be placed horizontally or diagonally at a location where it is used or stored. By configuring the display device 1 in this way, it can also be used for such objects O.

[0052] Even when the object O is a seasoning or the like, some users may place it horizontally on a shelf or the like in a storage area such as a pantry. By configuring the display device 1 in this way, it can be attached to the bottom of the body of the object O in the storage area and can be reattached to the top of the cap C when it is used, thereby meeting a variety of needs.

[0053] As shown in Figure 5, the peripheral wall 3 is preferably configured so that the gap G is equal to or larger than the width E of the hook C2 (the linear distance from the outer periphery of the cap C to the tip C21). Caps C attached to bottles, etc., have small hooks C2 that are difficult for fingers to grip and are prone to slipping when opening and closing. When a user hooks their finger on the hook C2 of the display device 1, they can also hook it onto the peripheral wall 3, increasing the area available for finger gripping and improving operability.

[0054] The peripheral wall 3 is preferably configured so that the shortest distance F between the lower outer edge 311, which is the outer edge of the lower end surface 31, and the tip C21 of the claw C2 is 20 mm or less. If the peripheral wall 3 and the cap C are too far apart, it becomes difficult to place one finger on both. Therefore, by configuring it in this way, one finger can reliably place one finger on both, ensuring operability.

[0055] As shown in Fig. 6, the display device 1 may have the center of the top plate 2 offset from the center of the cap C. When the display device 1 is configured with a wide display surface, it is possible to configure the display device 1 so that the center of the top plate 2 and the center of the cap C coincide with each other, leaving a uniform gap G around the cap C, as shown in Fig. 1(b), from the standpoint of facilitating balance and avoiding collisions with surrounding objects. On the other hand, when the top plate 2 is relatively narrow, it is preferable to offset the top plate 2 as shown in the figure, thereby making the gap G on the claw C2 side larger and ensuring the ease of opening and closing the claw C2.

[0056] <Modification 1 of Embodiment 1> Figure 7 is a cross-sectional view illustrating a display device of Modification 1 of Embodiment 1. The display device 1 of this example has the same configuration as that of the above-mentioned Embodiment 1 except for the adhesive portion 4, and achieves the same effects. Below, a description of the same points as those of the above-mentioned Embodiment 1 will be omitted as appropriate, and the description will focus on the differences.

[0057] In this example, the adhesive portion 4 has a lower surface that is an arcuate surface that is concave upward toward the inside. More specifically, as shown in the figure, the adhesive portion 4 has an upper surface that is flat (planar) like the lower surface 22 of the top plate 2, and a lower surface that is concave upward in an arcuate shape. In other words, the adhesive portion 4 is configured so that its thickness becomes thinner toward the inside.

[0058] The cap C of a container such as a bottle may have an upper surface that is an upwardly convex arcuate surface. By configuring the adhesive portion 4 in this manner, the display device 1 of this example can be attached in close contact with the convex cap C.

[0059] <Modification 2 of Embodiment 1> Figure 8 is a cross-sectional view illustrating a display device of Modification 2 of Embodiment 1. The display device 1 of this example has the same configuration as that of the above-mentioned Embodiment 1, except for the underside 22 of the top plate 2 and the adhesive portion 4, and achieves the same effects. Below, a description of the same points as those of the above-mentioned Embodiment 1 will be omitted as appropriate, and the description will focus on the differences.

[0060] In this example, the top plate 2 has a lower surface 22 that is an arc-shaped surface that is concave upward toward the inside. More specifically, as shown in the figure, the top plate 2 has a flat upper surface 21 and a lower surface 22 that is concave upward in an arc-like shape. In other words, the top plate 2 is configured so that its thickness becomes thinner toward the inside.

[0061] As shown in the figure, the adhesive portion 4 has an upper surface that is an arcuate surface that is convex upward inward to correspond to the underside 22 of the top plate 2, and a lower surface that is an arcuate surface that is concave upward inward. In other words, the adhesive portion 4 has a substantially uniform thickness and is provided in an arcuate shape along the underside 22 of the top plate 2.

[0062] The caps C of containers such as bottles often have an upper surface that is a convex arcuate surface. By configuring the lower surface 22 of the top plate 2 in this manner, the display device 1 of this example can be attached to the convex cap C in close contact even when the adhesive portion 4 has a uniform thickness.

[0063] 9A and 9B are diagrams illustrating a display device of Modification 3 of Embodiment 1, with (a) an example of a front view and (b) another example of a front view. The display device 1 of this example has the same configuration as that of Embodiment 1 above, except for the display 10, and achieves the same effects. Below, a description of the same points as in Embodiment 1 above will be omitted as appropriate, and differences will be mainly described.

[0064] In this example, the display 10 has a three-dimensional shape. The display 10 is reminiscent of the object O and is provided on the upper surface 21 of the tabletop 2. For example, if the object O is strawberry syrup, the display 10 may be in the three-dimensional shape of a strawberry as shown in FIG. 9( a). For example, if the object O is soy sauce, the display 10 may be in the three-dimensional shape of a soybean as shown in FIG. 9( b).

[0065] The display device 1 of this embodiment can further improve its distinguishability by configuring the display 10 to be more conspicuous in this way.

[0066] The display 10 of the display devices 1 of the first and second modifications of the first embodiment may also be configured in this manner.

[0067] 10 and 11 are diagrams for explaining a display device of embodiment 2, where Fig. 10(a) is a plan view, Fig. 10(b) is a front view, Fig. 10(c) is a bottom view, and Fig. 11 is a cross-sectional view. Fig. 12 is a diagram showing an example of use of the display device of embodiment 2.

[0068] The display device 1 of this embodiment has the same configuration as the first embodiment except for the upper surface 21 of the top plate 2, and has the same effects. Below, the description of the same points as the first embodiment will be omitted as appropriate, and the differences will be mainly described.

[0069] In the display device 1 of this embodiment, as shown in the figure, the top surface 21 of the top plate 2 is an arcuate surface that is convex upward toward the center. The bottom surface 22 of the top plate 2 is a flat surface. In other words, the top plate 2 is configured so that its thickness increases toward the center.

[0070] By configuring the display device 1 of this embodiment in this manner, the distinguishability is further improved even when the display 10 is displayed in the same manner as in the first embodiment. For example, as shown in Fig. 10(b), part of the display 10 can be seen from the front.

[0071] The wider the top plate 2 of the display device 1, the better the visibility and visibility from an oblique angle, but there is a limit to how wide the top plate 2 can be. For example, if the diameter of the top plate 2 is too large compared to the cap C, the adhesive area with the cap C becomes relatively small, resulting in a relatively low adhesive strength. It is also prone to interfering with surrounding objects. The display device 1 of this embodiment changes the height of the top plate 2 without changing the planar (XZ) area, thereby eliminating these drawbacks and improving visibility.

[0072] <Modification 1 of Embodiment 2> Figure 13 is a cross-sectional view for explaining a display device of Modification 1 of Embodiment 2. The display device 1 of this example has the same configuration as that of the above-mentioned Embodiment 2 except for the adhesive portion 4, and achieves the same effects. Below, a description of the same points as those of the above-mentioned Embodiment 2 will be omitted as appropriate, and the description will focus on the differences.

[0073] In this example, the adhesive portion 4 has a lower surface that is an arcuate surface that is concave upward toward the inside. More specifically, as shown in the figure, the adhesive portion 4 has an upper surface that is flat like the lower surface 22 of the top plate 2, and a lower surface that is concave upward in an arcuate shape. In other words, the adhesive portion 4 is configured so that its thickness becomes thinner toward the inside.

[0074] The cap C of a container such as a bottle may have an upper surface that is an upwardly convex arcuate surface. By configuring the adhesive portion 4 in this manner, the display device 1 of this example can be attached in close contact with the convex cap C.

[0075] <Modification 2 of Embodiment 2> Figure 14 is a cross-sectional view illustrating a display device of Modification 2 of Embodiment 2. The display device 1 of this example has the same configuration as that of the above-described Embodiment 2, except for the underside 22 of the top plate 2 and the adhesive portion 4, and achieves the same effects. Below, a description of the same points as those of the above-described Embodiment 2 will be omitted as appropriate, and the description will focus on the differences.

[0076] In this example, the top plate 2 has a lower surface 22 that is an arcuate surface that is concave upward as it extends inward. More specifically, as shown in the figure, the top plate 2 has an upper surface 21 that protrudes upward in an arcuate shape, and a lower surface 22 that recesses upward in an arcuate shape. The radius of the arcuate surface of the lower surface 22 may be the same as or different from the radius of the arcuate surface of the top surface 21. When the two radii are the same, the top plate 2 is configured to have a uniform thickness.

[0077] As shown in the figure, the adhesive portion 4 has an upper surface that is an arcuate surface that is convex upward inward to correspond to the underside 22 of the top plate 2, and a lower surface that is an arcuate surface that is concave upward inward. In other words, the adhesive portion 4 has a substantially uniform thickness and is provided in an arcuate shape along the underside 22 of the top plate 2.

[0078] The caps C of containers such as bottles often have an upper surface that is a convex arcuate surface. By configuring the lower surface 22 of the top plate 2 in this manner, the display device 1 of this example can be attached to the convex cap C in close contact even when the adhesive portion 4 has a uniform thickness.

[0079] <Modification 3 of Embodiment 2> Figure 15 is a cross-sectional view for explaining a display device of Modification 3 of Embodiment 2. The display device 1 of this example has the same configuration as Modification 2 of Embodiment 2 above, and achieves the same effects, except for the spacer 5 and adhesive portion 4. Below, a description of the similarities with Modification 2 of Embodiment 2 above will be omitted as appropriate, and the differences will be mainly described.

[0080] In the display device 1 of this example, as shown in the figure, the underside 22 of the top plate 2 is an arc-shaped surface that is concave upward as it goes inward. The spacer 5 is used to fill the arc-shaped space in cross section formed by the underside 22 of the top plate 2. The upper surface of the spacer 5 is configured as an arc-shaped surface that is convex upward, and the lower surface is configured as a flat surface. The material of the spacer 5 is not particularly limited, and epoxy resin, for example, is used.

[0081] Here, the adhesive portion 4 is configured to have a uniform thickness, and both the upper and lower surfaces are flat. The adhesive portion 4 is adhered to the flat lower surface of the spacer 5. In other words, the spacer 5 is provided between the lower surface 22 of the top plate 2 and the adhesive portion 4, filling the cavity between them.

[0082] The display device 1 of Modification 2 of the above-described Embodiment 2 is suitable for caps C with convex upper surfaces, but is difficult to use with caps C with flat upper surfaces because it does not adhere tightly to them. The display device 1 of this example is provided with a spacer 5, making it suitable for caps C with either convex or flat upper surfaces.

[0083] The display device 1 of the second modification of the first embodiment may be provided with a similar spacer 5 so as to be applicable to caps C with either a convex or flat top surface.

[0084] 16 is a diagram illustrating a display device of Modification 4 of Embodiment 2, with (a) a cross-sectional view and (b) a cross-sectional view of another example. The display device 1 of this example has the same configuration as Modification 2 of Embodiment 2 above, except for the abutment portion 32 of the peripheral wall 3, and achieves the same effects. Below, a description of the similarities with Modification 2 of Embodiment 2 above will be omitted as appropriate, and the differences will be mainly described.

[0085] As shown in the figure, the abutment portion 32 is provided so as to protrude inward from the inner peripheral surface of the peripheral wall 3. The abutment portion 32 has a width sufficient to abut against the outer peripheral surface of the cap C, and abuts against the outer peripheral surface of the cap C in use. The abutment portion 32 may be generally rectangular in cross section with its lower end surface flush with the lower end surface 31 of the peripheral wall 3, as shown in FIG. 16( a), or may have a triangular shape with its tip pointing inward. The abutment portion 32 may be provided with a plurality of rectangular portions spaced apart in cross section, as shown in FIG. 16( b). The abutment portion 32 may have a contact surface formed in a jagged shape, a wavy shape, or the like.

[0086] By providing the contact portion 32 in this way, the display device 1 of this example also contacts the outer peripheral surface of the cap C, thereby improving the unity with the cap C.

[0087] The contact portion 32 may be provided on the display device 1 of the second embodiment or its first or third modifications, or on the display device 1 of the first embodiment or any of its modifications.

[0088] <Variation 5 of Embodiment 2> Figure 17 is a plan view illustrating a display device of Variation 5 of Embodiment 2. The display device 1 of this example has the same configuration as Variation 2 of Embodiment 2 above, with the exception of the anti-slip portion 33, and achieves the same effects. Below, we will omit the description of the similarities with Variation 2 of Embodiment 2 above, and will focus on the differences.

[0089] The anti-slip portion 33 is provided on the outer peripheral surface of the peripheral wall 3. As an example, the anti-slip portion 33 is formed in a jagged shape in a plan view, and is composed of a plurality of triangular portions in a plan view as shown in the figure. The anti-slip portion 33 may be provided on a part of the outer peripheral surface of the peripheral wall 3 with a vertical width narrower than the height of the peripheral wall 3, or may be provided around the entire circumference. The anti-slip portion 33 may be provided over the entire height of the peripheral wall 3, reaching the top plate 2 and forming the outer edge of the upper surface 21.

[0090] The display device 1 of this embodiment is configured in this way, which further provides an anti-slip effect, thereby further improving operability, particularly in the case of a screw-type cap C.

[0091] The anti-slip portion 33 may be provided on the display device 1 of the second embodiment or its first, third, or fourth modifications, or on the display device 1 of the first embodiment or any of its modifications.

[0092] <Variation 6 of Embodiment 2> Figure 18 is a front view illustrating a display device of Variation 6 of Embodiment 2. The display device 1 of this example has the same configuration as Variation 2 of Embodiment 2 above, with the exception of the through-hole 34, and achieves the same effects. Below, we will omit the description of the similarities with Variation 2 of Embodiment 2 above, and will focus on the differences.

[0093] The through-hole 34 is provided so as to penetrate the thickness of the peripheral wall 3. The through-hole 34 may be provided so as to reach a part of the top plate 2. Some caps C for containers of seasonings or the like have a pipe-shaped spout. The display device 1 of this example is provided with the through-hole 34, so that the pipe-shaped spout can be passed through, and is therefore compatible with such caps C.

[0094] The through-hole 34 may be provided in the display device 1 of the second embodiment or its modifications 1, 3, 4, or 5, or may be provided in the display device 1 of the first embodiment or any of its modifications.

[0095] <Embodiment 3> Figures 19 and 20 are diagrams for explaining a display device of embodiment 3, where Figure 19(a) is a plan view, Figure 19(b) is a front view, Figure 19(c) is a cross-sectional view, Figure 20(a) is a rear view, Figure 20(b) is a right side view, and Figure 20(c) is a bottom view.

[0096] The display device 1 of this embodiment has the same configuration as the first embodiment except for the protrusion 6 and provides the same effects. Below, the description of the same points as the first embodiment will be omitted as appropriate, and the differences will be mainly described.

[0097] Here, the top plate 2 has a protrusion 6 extending upward from a portion of the edge of the upper surface 21. As shown in the figure, the protrusion 6 is configured to have a chord length J that is an arc of a central angle α along the edge of the upper surface. The protrusion 6 is preferably provided at a position corresponding to the claw C2. As an example, the protrusion 6 is configured so that the chord length J is equal to that of the claw C2. As an example, the protrusion 6 is configured so that the central angle α is within 180 degrees. The cross-sectional shape of the protrusion 6 is not particularly limited.

[0098] The hinge-type cap C is often opened by hooking the thumb on the nail C2 from below or diagonally below and lifting the nail C2 upward, but this can be made easier by placing another finger on the top surface of the cap C to assist. However, the finger placed on the top surface of the cap C may slip off and get in the way. The display device 1 of this embodiment is provided with the protrusion 6, which prevents the finger placed on the top surface 21 of the top plate 2 from slipping off, further improving the operability of the cap C.

[0099] The protrusion 6 may be provided on any of the display devices 1 of the first embodiment.

[0100] 21 is a diagram for explaining a display device of Modification 1 of Embodiment 3, where (a) is a plan view, (b) is a front view, (c) is a bottom view, and (d) is a cross-sectional view. The display device 1 of this example has the same configuration as that of the above-mentioned Embodiment 3 except for the protrusion 6, and achieves the same effects. Below, a description of the same points as those of the above-mentioned Embodiment 3 will be omitted as appropriate, and the description will focus on the differences.

[0101] The indicator 1 of this example has protrusions 6 provided all around the edge of the top surface 21. When placing a finger on the top surface of the cap C to assist, multiple fingers may be placed on the top surface, and the placement position varies depending on the dominant hand. Also, some users may open the cap C with their nail C2 facing left or right rather than toward the user. The indicator 1 of this example can accommodate such cases by providing protrusions 6 all around the circumference.

[0102] 22 is a diagram for explaining a display device of Modification 2 of Embodiment 3, where (a) is a plan view, (b) is a front view, (c) is a bottom view, and (d) is a cross-sectional view. The display device 1 of this example has the same configuration as Modification 1 of Embodiment 3 above, except for the upper surface 21 of the top plate 2, and achieves the same effects. Below, a description of the same points as in Modification 1 of Embodiment 3 above will be omitted as appropriate, and the description will focus on the differences.

[0103] In the display device 1 of this example, the top surface 21 of the tabletop 2 is configured as an arcuate surface that convexes upward toward the center. If the protrusions 6 were provided along the entire periphery of the edge of the top surface 21, the operability of opening and closing would be improved, but there is a risk of the discernibility of the display 10 being reduced. By configuring the top surface 21 of the tabletop 2 in this way, the display device 1 of this example can reduce the reduction in discernibility.

[0104] Fourth Embodiment FIG. 23 is a schematic diagram for explaining a display device according to a fourth embodiment, where (a) is a plan view and (b) is a right side view.

[0105] The display device 1 of this embodiment is similar in configuration to the first embodiment and achieves similar effects, except that it includes a movable plate 7 on which a display 10 is displayed, and that it includes a connection portion 8 for connecting the movable plate 7 to the top plate 2. Below, a description of the same points as the first embodiment will be omitted as appropriate, and the differences will be mainly described.

[0106] The movable plate 7 is connected to the upper surface 21 of the tabletop 2 by a connection part 8 so that the display angle can be changed. The movable plate 7 is preferably configured so that it can be folded onto (stacked on top of) the upper surface 21 of the tabletop 2. The connection part 8 is, for example, configured as a hinge that can rotate 90 degrees or 180 degrees. Preferably, the movable plate 7 is configured so that it can rotate any angle within 90 degrees or 180 degrees around the axis of the connection part 8 as a rotation axis, and can maintain its posture after rotation.

[0107] The attachment position of the connection part 8 is not particularly limited as long as it is within the range of the upper surface 21 of the tabletop 2. The connection part 8 is preferably attached to the edge of the tabletop 2 as shown in the drawing.

[0108] 23(a), for example, the display 10 is provided on the upper surface 71 of the movable plate 7. In this case, by adjusting the angle of the movable plate 7, the display 10 can be easily identified from any angle, including from the side where the connection portion 8 is installed and from above.

[0109] As an example, the display 10 is provided on both the upper surface 21 of the tabletop 2 and the lower surface 72 of the movable plate 7. In this case, by adjusting the angle of the movable plate 7, the display 10 can be easily identified from any angle, including from above and from the side opposite to the installation side of the connection portion 8.

[0110] As an example, the indicia 10 are provided on the upper surface 21 of the tabletop 2 and the upper surface 71 and lower surface 72 of the movable plate 7. In this case, the indicia 10 can be easily identified from both the installation side and the opposite side of the connection portion 8, and from any angle, in addition to from above.

[0111] As an example, the movable plate 7 has flat upper and lower surfaces 71 and 72 as shown in the figure. Alternatively, one or both of the upper and lower surfaces 71 and 72 of the movable plate 7 may be arcuate surfaces that are convex upward. This configuration can further improve the identifiability.

[0112] The movable plate 7 and the connecting portion 8 may be provided in the display device 1 of the third embodiment. In this case, the connecting portion 8 is disposed at a position where it does not interfere with the protruding portion 6.

[0113] <Modification 1 of Embodiment 4> Figure 24 is a schematic diagram for explaining a display device of Modification 1 of Embodiment 4. The display device 1 of this example has the same configuration as that of the above-mentioned Embodiment 4, except for the movable plate 7 and the connection portion 8, and achieves the same effects. Below, a description of the same points as those of the above-mentioned Embodiment 4 will be omitted as appropriate, and the description will focus on the differences.

[0114] Similar to the fourth embodiment, the display device 1 of this example includes a movable plate 7 connected to the upper surface 21 of the tabletop 2 so that the display angle can be changed. The movable plate 7 is connected to the tabletop 2 so that the angle can be changed three-dimensionally. In other words, the movable plate 7 is configured to be rotatable three-dimensionally above the tabletop 2. As an example, the connection part 8 is configured with a universal joint, so that the movable plate 7 can be rotated to any angle and can maintain its position after rotation.

[0115] The attachment position of the connection part 8 is not particularly limited as long as it is within the range of the upper surface 21 of the tabletop 2. The connection part 8 is preferably attached to the center of the tabletop 2 as shown in the drawing.

[0116] As shown in the figure, the display 10 is provided on the upper surface 71 of the movable plate 7. By adjusting the angle of the movable plate 7, the display device 1 can be easily viewed from any angle, further improving its distinguishability.

[0117] For example, the movable plate 7 has a flat upper surface 71. For example, the movable plate 7 has an upper surface 71 that is an upwardly convex arcuate surface.

[0118] The movable plate 7 and the connecting portion 8 may be provided in the display device 1 of the first modified example of the third embodiment.

[0119] Although the display device 1 according to the present invention is suitable for the object O contained in a bottle-shaped container, the container for containing the object O is not limited to this and other containers may be used. If the object O itself has a size and shape that allow the display device 1 to be attached, the display device 1 may be attached to the object O itself.

[0120] The above describes the embodiments and variations of the display device according to the present invention, but these are merely examples of the present invention and the present invention is not limited to these. The present invention also includes combinations of the above and subsequent embodiments and variations thereof, as well as various other variations. Various additions, modifications, and partial deletions are possible within the scope of the conceptual idea and spirit of the present invention, which can be derived from the content defined in the claims and their equivalents.

[0121] <Display Device Example 1> Figure 25 is a diagram showing an example of a display device. The illustrated display device 1 has one protruding anti-slip portion 33 on the outer peripheral surface of the peripheral wall 3. The anti-slip portion 33 is provided so as to protrude outward from the outer peripheral surface of the peripheral wall 3. In other words, the anti-slip portion 33 has a shape that protrudes outward from the outer periphery of the top plate 2, which is circular in plan view.

[0122] The indicator 1 has such a non-slip portion 33 on a part of the outer periphery of the peripheral wall 3, which makes it easy to hook a finger on it and turn it horizontally. It also makes it easy to hook a finger on the non-slip portion 33 and lift it upward. Furthermore, by aligning the protruding direction of the non-slip portion 33 with the direction of the cap C (the direction of the opening of the cap C), it is also possible to indicate the direction of the cap C.

[0123] The anti-slip portion 33 is preferably formed in a generally triangular shape in plan view as shown in the figure, is formed relatively large so that it is easy to hook a finger, and is formed so that the tip is rounded.

[0124] In addition to the protruding anti-slip portions 33, the display device 1 may also be provided with recessed anti-slip portions in other parts of the outer circumferential surface of the peripheral wall 3. By configuring the display device 1 in this manner, the rotational operability of the display device 1 is further improved.

[0125] Each of the above-described configurations can be applied to the display device 1 shown in the illustrations, except in cases where it is clearly considered not to be the case in principle (the same applies to each of the following examples).

[0126] <Example 2 of Display Tool> FIG. 26 shows an example of a display tool, where (a) shows an example of a state of use, and (b) shows another example of the cap C of (a).

[0127] As described above, when the condiment or the like contained in the bottle runs out, the display device 1 can be removed and attached to another bottle for repeated use. As described above, the adhesive portion 4 has adhesive strength on both the upper and lower surfaces. From the perspective of ease of replacement, it is desirable that the adhesion between the upper surface of the adhesive portion 4 and the lower surface 22 of the top plate 2 is stronger than the adhesion between the lower surface of the adhesive portion 4 and the upper surface of the cap C. The ease of replacement and adhesion of the display device 1 can be adjusted by changing the contact area between the lower surface of the adhesive portion 4 and the upper surface of the cap C.

[0128] As described above, the display device 1 can have either or both of the underside 22 of the top plate 2 and the underside of the adhesive portion 4 configured as concave arc surfaces. In this case, as shown in FIG. 26( a), if the degree of concavity of this underside is greater than the degree of protrusion of the upper surface of the cap C, there will be a portion (S) where the two do not adhere to each other, and the greater the difference, the larger the portion where they do not adhere to each other. For example, if the radius of the arcuate surface of the underside of the adhesive portion 4 is smaller than the radius of the arcuate surface of the upper surface of the cap C, as shown in the figure, the portion near the periphery will adhere to each other, but the central portion will not adhere to each other, making it relatively easy to replace. In this way, the display device 1 can have either or both of the underside 22 of the top plate 2 and the underside of the adhesive portion 4 configured as concave arc surfaces, and the degree of concavity can be adjusted to adjust the adhesion to the cap C.

[0129] As shown in Figure 26 (b), even if the cap C has a flat upper surface and an R or C surface on its outer periphery, this R or C surface adheres closely to the concave surface on the underside of the adhesive portion 4, and other parts do not adhere closely to the concave surface of the adhesive portion 4, making it relatively easy to replace.

[0130] <Display Device Example 3> Figure 27 shows an example of a display device, with (a) a bottom view of one example and (b) a diagram showing an example of how it is used. As shown in the figure, the display device 1 can be configured such that the adhesive portion 4 is configured in a doughnut shape with a hole in the center, so that there is always a portion that is not in close contact with the cap C. This reduces the contact area between the underside of the adhesive portion 4 and the top surface of the cap C, making it easier to replace.

[0131] More specifically, as shown in the figure, the display device 1 has a doughnut-shaped adhesive portion 4, and even if the degree of protrusion of the convex upper surface of the cap C corresponds to the degree of depression of one or both of the underside 22 of the top plate 2 and the underside of the adhesive portion 4, a portion in the center that does not adhere to the cap C can always be provided, thereby adjusting the adhesion in a direction that reduces adhesion to make replacement easier. Note that the through-hole (adhesive portion adjustment hole) in the center of the adhesive portion 4 is a perfect circle in the example shown, but it may be other shapes such as an oval or polygon.

[0132] In the display device 1 of this example, when the degree of protrusion of the convex upper surface of the cap C is smaller than the degree of concavity of one or both of the underside 22 of the top plate 2 and the underside of the adhesive portion 4, there may be a portion (S) where the two do not adhere further near the edge of the through hole in the center of the adhesive portion 4, but they adhere in the area near the periphery, as in the example of Figure 26. Furthermore, in the display device 1 of this example, even when the degree of protrusion of the convex upper surface of the cap C is greater than the degree of concavity of one or both of the underside 22 of the top plate 2 and the underside of the adhesive portion 4, the central portion of the upper surface of the cap C will fit into the through hole in the center of the adhesive portion 4, and the two will adhere in close contact near the edge of the through hole. In this way, the display device 1 of this example is suitable for various caps C with different degrees of protrusion, and the adhesion can also be adjusted.

[0133] <Embodiment 5> Fig. 28 is a diagram for explaining a display device of embodiment 5, where (a) is an example of a perspective view, (b) is an example of an right side view, and (c) is an example of an rear view. Fig. 29 is a diagram for explaining the display device of embodiment 5, and is a cross-sectional view.

[0134] The display device 1 of this embodiment differs from the above-described embodiment and its variations, and display device examples 1 to 3 (hereinafter collectively referred to as "previous examples"), mainly in that it includes a clearance portion 36. The configurations of the previous examples can be applied to the display device 1 of this embodiment (the same applies to the variations described below), except in cases where it is clearly considered that this is not the case in principle. The following explanation will focus on the differences.

[0135] Similar to the above-described example, the display device 1 is attached to the surface of the object O in order to display the object O. The display device 1 comprises a top plate 2 that is wider than the surface of the object O, a peripheral wall 3 that extends cylindrically downward from the edge of the underside of the top plate 2, and an adhesive portion 4 that is provided below the top plate 2 and inside the peripheral wall 3. The top plate 2 may be circular in plan view, or may have any other shape.

[0136] As an example, the peripheral wall 3 has a convex anti-slip portion 33 (hereinafter, the convex anti-slip portion will be referred to as the "first anti-slip portion") that protrudes outward from the outer circumferential surface. The first anti-slip portion 33 is generally triangular, relatively large so that it is easy to hook a finger on, and has a rounded overall shape. By having the first anti-slip portion 33, the display device 1 becomes easy to hook a finger on and turn horizontally, and also easy to hook a finger on and lift upward. The first anti-slip portion 33 is located on the installation side of the claw C2 of the cap C. Hereinafter, the installation side of the claw C2 of the cap C will be referred to as the front.

[0137] As an example, the peripheral wall 3 has a recessed anti-slip portion 35 (hereinafter, the recessed anti-slip portion is referred to as the "second anti-slip portion") that recesses inward on the outer circumferential surface. The second anti-slip portion 35 preferably has a gently curved surface that makes it easy for a finger to rest against. One or more second anti-slip portions 35 are provided. When the peripheral wall 3 has the first anti-slip portion 33, preferably, one second anti-slip portion 35 is provided rearward opposite the first anti-slip portion 33, and two pairs of second anti-slip portions 35 are further provided symmetrically between the rear second anti-slip portion 35 and the first anti-slip portion 33. Placing a finger against the second anti-slip portion 35 when operating the display device 1 further improves rotational operability, particularly in the case of a screw-type cap C.

[0138] The peripheral wall 3 has a notched clearance portion 36 in part of its lower end. The clearance portion 36 is a notched portion cut out upward, in other words, a shape in which part of the lower end surface 31 is recessed upward. When the peripheral wall 3 has the first anti-slip portion 33, the clearance portion 36 is provided in a position facing the first anti-slip portion 33, i.e., at the rear. When the peripheral wall 3 has the second anti-slip portion 35, as in the illustrated example, the rear second anti-slip portion 35 has a shorter vertical width than the other second anti-slip portions 35 because of the clearance portion 36 located below it.

[0139] There are various types of hinge-type caps C having a claw C2 at the front and a hinge C1 at the rear, and some have the hinge C1 located near the top surface of the cap C, with the distance between the hinge C1 and the top surface being short.

[0140] 29, if the hinge C1 is located near the top surface of the cap C, when opening the cap C, the rear portion of the peripheral wall 3 may come into contact with (get caught on) the lower peripheral wall C3 of the cap C, preventing the cap C from opening sufficiently. For example, if the cap C is prevented from opening more than 90 degrees, the weight of the cap C and the elastic force (restoring force) of the hinge C1 may cause the cap C to close on its own.

[0141] In this form of display device 1, a clearance portion 36 is provided by cutting away the rear lower end portion of the peripheral wall 3 (the portion shown by the dotted line in the illustration), thereby reducing the height of a portion of the peripheral wall 3, thereby avoiding collision with the lower peripheral wall C3 of the cap C and allowing the cap C to be opened at a sufficiently large angle so as not to close on its own.

[0142] Although it is possible to deal with this by reducing the height H (see FIG. 1(b)) of the peripheral wall 3 as a whole, it may be easier to reduce the height H partially and provide a clearance portion 36. It is also considered that providing the clearance portion 36 can accommodate a wider variety of caps C than reducing the height H.

[0143] The display device 1 is provided (shipped, etc.) with the upper surface of the adhesive portion 4 attached to the underside 22 of the top plate 2, for example, and a protective release sheet (also called a release film) attached to the underside of the adhesive portion 4. The planar shape of the release sheet is usually substantially the same as the planar shape of the adhesive portion 4. Therefore, when attaching the display device 1 to the cap C, it is necessary to first remove this release sheet. This release sheet is usually removed from the outside, but in doing so, fingers may come into contact with the peripheral wall 3, making it difficult to remove.

[0144] The display device 1 of this embodiment has a clearance area 36 on the peripheral wall 3, which provides an opening through which fingers can reach and easily peel off the release sheet. The clearance area 36 is preferably provided in a gentle curve to reduce discomfort even when the fingers come into contact with it.

[0145] Furthermore, to improve the ease of peeling, the planar shape of the release sheet may be different from that of the adhesive portion 4. As an example, at least a portion of the outer edge of the release sheet may be extended beyond the outer edge of the adhesive portion 4 to function as a gripping portion for grasping with the fingers. A specific example is shown in Figures 34(a) and (b). Figure 34(b) is a view of the display device 1 from below. In this example, the adhesive portion 4 is an octagon, with four corners removed from a roughly square, and is sized to fit within the underside 22. Meanwhile, the release sheet 41 has a gripping portion 42, which is added to the same shape as the adhesive portion 4 and has an extended central portion at the rear. The gripping portion 42 is folded downward and then outward, exposing below and outside the clearance portion 36. This configuration improves the ease of peeling. Of course, release sheets with gripping portions can also be provided in other embodiments and modified examples.

[0146] <Modification 1 of Embodiment 5> FIG. 30 is a perspective view observed from above for explaining an example of a display device according to Modification 1 of Embodiment 5. In FIG.

[0147] The display device 1 of this example differs from the fifth embodiment mainly in that it includes a display 12 that indicates the orientation of the cap C (the position of the operating part or the direction of the operating motion). Hereinafter, the displays 10 and 11 that represent the object O will be referred to as first displays, and the display that indicates the orientation of the cap C of the container that contains the object O (the position of the operating part or the direction of the operating motion) will be referred to as second displays. The following description will focus on the second display 12.

[0148] Here, the second indicia 12 indicates the installation side of the hook C2 of the hinge-type cap C. The display device 1 of this example has a three-dimensional second indicia 12. As an example, as shown in the figure, the second indicia 12 is provided three-dimensionally near the tip (including the tip and its vicinity) of the first anti-slip portion 33, from the circumferential surface to the upper surface, protruding from the surface so as to be identifiable by touch. The shape of the second indicia 12 is not particularly limited, and may be a tapered protrusion that is slightly wider at the bottom and slightly narrower at the top, as shown in the figure, or may be another shape.

[0149] In the display device 1, if the direction of the first indicia 10 and the protruding direction of the first anti-slip portion 33 are aligned with the direction of the cap C, the direction of the cap C can be identified visually, and the removed object O can be opened without having to re-grasp it. On the other hand, if the first indicia 10 is not tactilely identifiable, such as in Braille, it may not be easily tactilely identifiable depending on the shape of the first anti-slip portion 33.

[0150] The indicating device 1 of this example has the second indicia 12 superimposed on the first anti-slip portion 33, allowing the orientation of the cap C to be instantly identified by touch. Note that the indicating device 1 may not have the first anti-slip portion 33, and the second indicia 12 may be provided on the outer peripheral surface of the peripheral wall 3 on the installation side of the claw C2 of the cap C, allowing the orientation of the cap C to be identified by touch.

[0151] <Modification 2 of Embodiment 5> Figure 31 is a perspective view observed from below for explaining an example of a display device according to Modification 2 of Embodiment 5. Note that the adhesive portion 4 is not shown. The display device 1 of this example differs from the above-described Modification 1 of this embodiment in the position where the second indicia 12 is arranged. The following description will focus on the differences.

[0152] As shown in the figure, the second indicia 12 of this example protrudes downward from the underside of the first anti-slip portion 33 and is provided three-dimensionally on the underside so as to be tactilely discernible. The specific shape of the second indicia 12 is not particularly limited, and it may be triangular as shown in the figure, or may be another shape. The display device 1 of this example achieves the same effects as the above-mentioned modification example 1.

[0153] <Variation 3 of Embodiment 5> Figure 32 is a diagram for explaining an example of a display device of Variation 3 of Embodiment 5, where (a) is a perspective view observed from below and (b) is a right side view. The adhesive portion 4 is not shown in Figure 32(a). The display device 1 of this example differs from the above-mentioned variations 1 and 2 of this embodiment in the position where the second indicia 12 is arranged. The following description will focus on the differences.

[0154] 32(a), the second indicia 12 in this example protrudes downward from the underside of the first anti-slip portion 33 and is provided three-dimensionally on the underside so as to be identifiable by touch. The specific shape of the second indicia 12 is not particularly limited, and may be a square shape as shown in the figure, or may be another shape.

[0155] 32(b), the second indicia 12 of this example is provided so that its tip protrudes from the side of the first anti-slip portion 33, or, although not shown, its tip protrudes forward of the first anti-slip portion 33, and further so that it can be distinguished by touch on the circumferential surface. This further improves the tactile distinguishability of the display device 1 of this example.

[0156] 33A and 33B are diagrams for explaining an example of an indicator according to Modification 4 of Embodiment 5, where (a) is a plan view of one example and (b) is a plan view of another example. The second indicator 12 in this example indicates the operating motion direction (operation direction) of the cap C. The following description will focus on the second indicator 12.

[0157] As described above, when the direction of the first indicia 10 and the protruding direction of the first anti-slip portion 33 of the display device 1 are aligned with the installation side of the claw C2 of the cap C, the operating position of the hinge-type cap C can be visually identified and the removed object O can be opened without having to re-grasp it. On the other hand, if the display device 1 is commonly applied to both the screw-type cap C and the hinge-type cap C, there is a risk that the user will be confused and unable to immediately distinguish the operating direction.

[0158] The display device 1 of this example solves this problem by including a second indicia 12 that indicates the direction of operation of the cap C. As shown in Figure 33(a), for example, the display device 1 can indicate that the cap C is a screw-type cap that requires rotation by providing, on its top surface, the second indicia 12, which is an arrow indicating the direction of rotation, together with the first indicia 10. As shown in Figure 33(b), for example, the display device 1 can indicate that the cap C is a hinge-type cap that requires vertical opening and closing by providing, on its top surface, the second indicia 12, which is an arrow pointing downward, together with the first indicia 10. Note that the second indicia 12 may be provided so as to hang over the first anti-slip portion 33.

[0159] 35A and 35B are diagrams for explaining a display device according to embodiment 6, in which (a) is an example of a cross-sectional view and (b) is an example of a bottom view. For ease of explanation, the adhesive portion is omitted from Fig. 35B.

[0160] The display device 1 of this embodiment differs from the fifth embodiment and its modifications in that it has an adjustment hole 23 in the top plate 2. In the following, the fifth embodiment and its modifications will be referred to for the common configuration, and the differences will be mainly described.

[0161] The top plate 2 has an adjustment hole 23 (top plate adjustment hole) for adjusting the adhesion with the target surface of the object O. The adjustment hole 23 is provided in approximately the center of the lower surface 22. More specifically, the adjustment hole 23 is a bottomed hole that opens to the lower surface 22, is recessed in the thickness direction, and has a bottom surface in a direction approaching the upper surface 21 (toward the upper surface 21). In other words, the adjustment hole 23 is a hole shaped by recessing (depressing) the center of the lower surface 22. The adjustment hole 23 may be configured to have a uniform depth, or may be configured to become deeper toward the inside. In other words, the bottom surface of the adjustment hole 23 may be a surface that is approximately parallel to the lower surface 22 (more precisely, the lower surface 22 when the adjustment hole 23 is not provided), or may be an upwardly concave arc surface if the lower surface 22 is a flat surface, or may be an upwardly concave arc surface with a different radius of curvature if the lower surface 22 is an upwardly concave arc surface.

[0162] In the display device 1, if the underside 22 of the top plate 2 is a flat surface or an arcuate surface with a large radius of curvature, and the adhesive portion 4 has a substantially uniform thickness, if the target surface of the object O, for example, the top surface of a cap C, protrudes significantly (e.g., nearly spherical), the adhesive area (contact area) between the target surface and the adhesive portion 4 may be small, potentially resulting in insufficient adhesive strength. The display device 1 of this embodiment has an adjustment hole 23 in the top plate 2, so that the center of the corresponding adhesive portion 4 is detached from the underside 22. When the top surface of the cap C is attached to the underside of the adhesive portion 4, the adhesive portion 4, which is softer than the cap C, conforms to the shape of the top surface of the cap C and enters the adjustment hole 23, thereby increasing the adhesive area. In other words, the adjustment hole 23 in the top plate 2 of this embodiment takes advantage of the adhesive portion 4's softer (more flexible) properties than the top plate 2 and cap C to provide a space for the center of the adhesive portion 4 to conform to the top surface of the cap C rather than the underside of the top plate 2.

[0163] In addition, when the display device 1 has an arcuate bottom surface 22 of the top plate 2 with a small radius of curvature (high degree of curvature) and the adhesive portion 4 with a substantially uniform thickness, if the target surface of the object O, such as the top surface of a cap C, protrudes only slightly (close to or is flat), the adhesive area (contact area) between the target surface and the adhesive portion 4 is small, and sufficient adhesive strength may not be obtained. Because the display device 1 of this embodiment has an adjustment hole 23 in the top plate 2, the center of the corresponding adhesive portion 4 is in an untouched state and is located slightly lower than in the case without the adjustment hole 23. Therefore, when attaching the top surface of the cap C, the center of the adhesive portion 4 tends to adhere relatively easily to the target surface, depending on the degree of curvature of the target surface. In other words, the adjustment hole 23 in the top plate 2 of this embodiment prioritizes adhesion to the top surface of the cap C over adhesion of the center of the adhesive portion 4 to the bottom surface 22 of the top plate 2, thereby improving adhesion to the target surface.

[0164] The adjustment hole 23 is not particularly limited, but from the viewpoint of ease of application, it is preferable that the shape of the opening is close to the planar shape of the cap C, and in the case of the cap C which is a perfect circle when viewed from above, a perfect circle when viewed from the bottom as shown in the example.

[0165] The size of the adjustment hole 23 is not particularly limited, but from the viewpoint of the balance between the adhesive strength between the upper surface of the adhesive portion 4 and the lower surface 22 of the top plate 2 and the adhesive strength between the lower surface of the adhesive portion 4 and the upper surface of the cap C, the upper limit of the diameter of the opening, when viewed from the bottom, is preferably 2 / 3 or less, and more preferably 1 / 2 or less, of the diameter of the lower surface 22. The lower limit of the diameter of the opening, when viewed from the bottom, is preferably 1 / 4 or more, and more preferably 1 / 3 or more, of the diameter of the lower surface 22.

[0166] The display device 1 of this embodiment can be adapted to the cap C more flexibly by providing the adjustment hole 23 in the top plate 2, and the applicability to the cap C is further improved.
