Description

Technical Field

[0001] The present invention relates to a display device for displaying an object.

Background Art

[0002] An object contained in an object, such as a bottle or a flask (hereinafter collectively referred to as "bottle"), is usually displayed on the outer peripheral surface of the body of the bottle, and it is difficult to identify what is contained from above.

[0003] Therefore, conventionally, for example, "a sample bottle with a cap characterized by comprising a content display means that allows the content 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 attached to the upper surface of the cap and having a content display described thereon" (see Claims 1 and 2 of Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0005] The above sample bottle has the effect that "even when the sample bottle with a cap is stored in a drawer, a shelf, etc. in a state where only the upper surface side of the cap can be seen for saving storage space, etc., the content display means can be seen in the displayed state without taking out each sample bottle one by one, so that the content of the sample bottle can be discriminated" (see Paragraph

[0010] of Patent Document 1).

[0006] On the one hand, for the sample bottle, a sheet-like member such as a paper or synthetic paper label that can be attached to the upper surface of the cap is adopted for the content display means. Since the sheet-like member is smaller than the upper surface of the cap, when the cap itself is small, the sheet-like member such as a paper or synthetic paper label becomes even smaller, resulting in a decrease in discriminability. In addition, such a sheet-like member such as a paper or synthetic paper label cannot be reused.

[0007] The present invention is for solving at least one of the above problems, and an object thereof is to provide a display tool with improved discriminability and easier usability.

Means for Solving the Problem

[0008] One aspect of the present invention for solving the above problems is a display tool used by attaching it to a target surface of an object for displaying the object, comprising a top plate wider than the target surface of the object, a peripheral wall extending downward in a cylindrical shape from an edge of the lower surface 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 to have a height greater than the thickness of the adhesive portion.

[0010] The lower surface of the adhesive portion may be an arcuate surface concave upward.

[0011] The lower surface of the top plate may be an arcuate surface concave upward.

[0012] The upper surface of the top plate may be an arcuate surface convex upward.

[0013] The lower surface of the top plate is an arcuate surface concave upward, and a spacer with a convex upper surface may be provided between the lower surface of the top plate and the adhesive portion.

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

[0015] The top plate may be provided with a movable plate connected to be able to change the display angle on the upper surface.

[0016] The peripheral wall may have a notch-shaped avoiding portion at a part of the lower end.

[0017] It may include at least one of a first display representing an object and a second display indicating the direction of a cap of a container for accommodating the object.

[0018] The top plate may have an adjustment hole for adjusting the adhesion to the target surface of the object.

Advantages of the Invention

[0019] According to the present invention, it is possible to provide a display tool with improved distinctiveness and better usability.

[0020] Problems, configurations, and effects other than those described above will be clarified by the description of the following embodiments.

Embodiments for Carrying Out the Invention

[0022] Hereinafter, examples of embodiments of the present invention will be described with reference to the drawings. For components common to the following embodiments and their modifications, the same reference numerals as those used above may be given, and the description may be omitted. In addition, when referring to the shape, positional relationship, etc. of components, unless otherwise specified or it is considered not to be so in principle, those substantially approximating or similar to the shape, etc. are included.

[0023] The object to which the display device according to the present invention is applied is typically an object contained in a container such as a bottle, and is, for example, food and drink such as seasonings, alcoholic beverages, and jams. Seasonings here include not only traditional ones such as soy sauce, mirin, cooking sake, vinegar, miso, and salt, but also edible oils, dressings, sauces, herbs, etc. Note that the object may be something other than food and drink. The object may be poured out or scooped out from the container, or may be used by spraying with a structure provided in the container.

[0024] The display device according to the present invention is particularly suitable for a bottle-shaped container. The bottle-shaped container includes, in addition to the bottle-shaped container for storing the above-mentioned food and drink, for example, a spray can. Such a container is not particularly limited in terms of material, and part or all of it may be made of resin, or part or all of it may be made of pottery, glass, metal, etc. Such a container has a body portion mentioned below, and appropriately includes a structure suitable for its use together with the cap or instead of the cap.

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

[0026] <Embodiment 1> FIGS. 1 and 2 are diagrams for explaining the display device of Embodiment 1. FIG. 1(a) is a plan view, FIG. 1(b) is a cross-sectional view taken along line AA of FIG. 1(a), FIG. 2(a) is a front view, FIG. 2(b) is a bottom view, FIG. 2(c) is a cross-sectional view taken along line AA of another example, and FIG. 2(d) is a cross-sectional view taken along line AA of still another example. FIG. 3 is a diagram for explaining the display device of Embodiment 1, where (a) is a diagram showing a usage example and (b) is a front view of another example. FIG. 4 is a diagram showing a usage example of the display device of Embodiment 1. FIGS. 5 and 6 are diagrams for explaining the display device of Embodiment 1. FIG. 5 is a partially enlarged view of FIG. 1(b), and FIG. 6 is a diagram for explaining another example of the usage state. In each figure, 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 in the following figures). The line AA coincides with the center line extending in the Z direction passing through the center of the display device, and unless otherwise specifically mentioned, the cross-sectional view is assumed to be a cross-sectional view taken along line AA. In the present application, the direction approaching the center line extending in the Y direction of the display device is defined as the inner side (inside).

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

[0028] The display tool 1 is used by attaching it to the target surface of such an object O in order to display the object O. The soy sauce in the bottle is placed in an upright posture with the cap C positioned on the upper side in a storage location, such as a drawer or a case (box, basket, etc.) installed under a cooking counter. Such a drawer or case may have side walls, making it difficult to identify the product label on the outer peripheral surface of the body portion of the bottle B. The target surface of the object O to which the display tool 1 is attached is the upper surface of the cap C in such an upright posture. The display tool 1 can also be used for a cap C with a screw structure (screw type), but here, a cap C with a hinge structure (hinge type), which is often seen in seasonings and the like, will be exemplified and described. The hinge-type cap C usually has a hinge C1 and a claw C2 on the opposite side of the hinge C1.

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

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

[0031] Since the display device 1 has a top plate 2 that is wider than the target surface of the object O in this way, even if the cap C is small, the upper surface 21 of the top plate 2 that serves as the display surface can be configured to be large, improving the discriminability of the display. Also, by configuring it in this way, it is possible to handle a variety of caps C of different sizes with fewer types of display devices 1.

[0032] The display 10 displayed on the upper surface 21 may be the name representing the object, an abbreviation, or a symbol, etc. When the display 10 is composed of a name or an abbreviation, these may be written in Chinese characters, hiragana, katakana, or alphabet. The display 10 may be black, red, or other colors. The display 10 may also be a combination of multiple colors.

[0033] As an example, the display 10 is directly printed on the upper surface 21. As an example, the display 10 is displayed such that a thin film-like object is attached to the upper surface 21 or a thin sheet-like object is laminated.

[0034] When the display 10 consists of multiple characters, it may be displayed in a uniform size, but preferably, from the perspective of improving discriminability, one or two or more characters are displayed larger than the others. For example, in the case of "mirin", "mi" is large and "rin" is small, and in the case of "black vinegar", "black" is large and "vinegar" is small. In the illustrated example, the name of the object O, "soy sauce", is displayed in Chinese characters, with "jiang" being large and "you" being small.

[0035] Preferably, the display 10 is displayed in a direction that can indicate the direction of the cap C. The direction of the cap C is, for example, the position of the operation part or the operation direction. For example, in the case of a hinge-type cap C, it can indicate the installation side of the claw C2. In the illustrated example, the lower side of the characters of the display 10 coincides with the installation side of the claw C2, and the upper side of the characters coincides with the installation side of the hinge C1. Thus, if the object O is placed along the direction of the display 10, it can be opened without having to hold the taken-out object O again, saving the trouble of re-holding.

[0036] The display 10 is, as an example, displayed so as to be visually distinguishable. The display 10 is, as an example, displayed so as to be distinguishable by touch such as Braille. The display 10 may be displayed so as to be distinguishable both visually and by touch. Since commercially available seasonings and the like usually do not have a tactile display such as Braille, by configuring it in this way, users who rely on touch can also easily identify it.

[0037] Seasonings and the like are often placed in the same location below the line of sight for a plurality of items, for example, in a drawer or a case (box, basket) under a cooking counter. It is often difficult to directly identify and take out the desired item because the product label on the outer peripheral surface of the body cannot be visually recognized due to the side walls of the drawer or case, surrounding objects, etc. Note that such a problem is not limited to the use of seasonings in the kitchen, but may also exist in the places where other objects are used. By having the above configuration, the display device 1 has high distinguishability from above and can easily identify and take out the desired item. Also, since the display 10 can indicate the direction of the cap C, the cap C can be quickly opened.

[0038] Note that the illustrated display device 1 is an example in which the display 10 has already been displayed by the manufacturer, but the display 10 may be displayed by the user who obtained it himself / herself. Since the types and placement locations of the objects O to be used may vary depending on the user, by configuring it in this way, it can respond more flexibly. For example, some users may use multiple types of soy sauce alone, such as light soy sauce and dark soy sauce. By configuring it in this way, it can respond more flexibly, for example, by displaying the display 10 such as "light" or "dark" instead of "soy sauce". Also, some users may open the claw C2 on the left or right side instead of in front. By configuring it in this way, the user can determine the direction of the display 10 himself / herself. The display 10 is, as an example, displayed by the user by handwriting. The display 10 is configured as a label formed separately from the main body including the top plate 2, the peripheral wall 3, and the adhesive portion 4, and may be provided to the user together with the main body.

[0039] As shown in Fig. 1(b), the peripheral wall 3 extends downward in a cylindrical shape from the edge of the lower surface 22 of the top plate 2 and has a height H (the degree of protrusion from the lower surface 22). The peripheral wall 3 is preferably configured such that the lower end surface 31 is located above (at a higher position) than the hinge C1 of the cap C. There may be a case where the gap G is smaller than the lateral width of the hinge C1. If the lower end surface 31 of the peripheral wall 3 comes to the same position as or below the hinge C1, it will interfere with the hinge C1. Thus, this configuration is adopted to avoid such interference.

[0040] The lower end surface 31 of the peripheral wall 3 is at the same position as or above the claw C2 of the cap C. That is, the distance from the lower end surface 31 of the peripheral wall 3 to the upper surface 21 of the top plate 2 is the same as or shorter than the distance from the lower end of the claw C2 to the upper surface 21. If the lower end surface 31 of the peripheral wall 3 comes below the claw C2, the peripheral wall 3 will interfere when trying to hook a finger on the claw C2 to open it. Thus, this configuration is adopted to avoid such interference.

[0041] The peripheral wall 3 may be formed by joining a separately formed part to the top plate 2, but preferably, it is formed integrally with the top plate 2. The top plate 2 and the peripheral wall 3 have at least the rigidity to maintain their shapes when attached to the object O, and more preferably, they have the rigidity to withstand being hooked by a finger when opening and closing the cap C.

[0042] The materials used for the top plate 2 and the peripheral wall 3 may be any as long as they satisfy the above configuration and are not particularly limited. As an example, plastic resin, metal, wood, etc. are used for the top plate 2 and the peripheral wall 3. One or both of the top plate 2 and the peripheral wall 3 may have a color. The top plate 2 and the peripheral wall 3 may have a common color or different colors. Thereby, in addition to the display 10, the display device 1 can also be identified by the color of one or both of the top plate 2 and the peripheral wall 3.

[0043] As shown in Fig. 1(b), as an example, the adhesive part 4 is provided on the lower surface 22 of the top plate 2 and is inside the peripheral wall 3. The adhesive part 4 has adhesive force on both the upper surface and the lower surface. As an example, the upper surface and the lower surface of the adhesive part 4 are configured as flat surfaces (plane surfaces) similar to the lower surface 22 of the top plate 2.

[0044] The adhesion part 4 is configured such that, as an example, the gap between it and the inner peripheral surface of the peripheral wall 3 becomes substantially zero as shown in Fig. 1(b). The adhesion part 4 may be configured to have a gap between it and the inner peripheral surface of the peripheral wall 3 as shown in Fig. 2(c).

[0045] As an example, the adhesion part 4 is configured such that, as shown in Fig. 2(d), the edge is bent downward to form a corner of an R surface or a C surface in cross-section. The cap C may have an R surface or a C surface on its outer peripheral part, and by configuring the adhesion part 4 in this way, the adhesion to the cap C can be improved.

[0046] The material of the adhesion part 4 is not particularly limited, and as an example, it is a reusable adhesive tape. By configuring the display device 1 with the adhesion part 4 in this way, when, for example, the seasoning such as soy sauce contained in the bottle is used up, it can be removed and attached to another bottle of soy sauce for repeated use.

[0047] The thickness of the adhesion part 4 is smaller than the height H of the peripheral wall 3. In other words, the height H of the peripheral wall 3 is larger than the thickness of the adhesion part 4, and the lower surface of the adhesion part 4 is at a position higher than the lower end surface 31 of the peripheral wall 3. By surrounding the adhesion part 4 with the peripheral wall 3 in this way, the display device 1 can reduce the adhesion and intrusion of dust. Also, the peripheral wall 3 serves as a stopper, making it difficult to shift horizontally.

[0048] As shown in Fig. 3(a), the display device 1 is preferably configured such that the diameter D is smaller than the maximum diameter I of the bottle B. By configuring the display device 1 to have a planar area that fits within the range of the planar area of the bottle B in this way, interference with surrounding objects can be reduced.

[0049] As shown in FIG. 3(b), the display device 1 may further have a display 11 on its outer peripheral surface. The outer peripheral surface of the display device 1 is configured to include the outer peripheral surface of the top plate 2 and the outer peripheral surface of the peripheral wall 3. The dashed line in FIG. 3(b) indicates the lower surface 22 of the top plate 2 and the inner peripheral surface of the peripheral wall 3 on the cutting plane that is orthogonal to the AA line, in other words, it indicates the thickness of the top plate 2 and the peripheral wall 3. The display device 1 may be configured to have a greater thickness K of the top plate 2 than in the above example in order to display the display 11 in a distinguishable size.

[0050] The display 11 can be configured by the same means as the above display 10, and detailed description thereof will be omitted here. The display 11 may be the same as the display 10 on the upper surface 21 of the top plate 2, or may be more concise. In the illustrated example, the display 11 is an abbreviation of "soy sauce" as "sho". The display 11 may be provided on a part of the outer peripheral surface one or more times, or may be repeatedly displayed at predetermined intervals over the entire outer peripheral surface as shown in the figure. In addition to the above display 10, the display device 1 can further be provided with the display 11, and the discriminability can be further improved.

[0051] As shown in FIG. 4, the object surface of the object O to which the display device 1 is attached may be the bottom surface of the body of the bottle B. In this case, the display device 1 is configured such that the inner peripheral diameter of the peripheral wall 3 is larger than the maximum diameter I of the bottle B. When the object O is, for example, wine in a bottle, etc., it may be placed horizontally or obliquely horizontally at the place of use or storage. By configuring the display device 1 in this way, it can also cope with such an object 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 place such as a pantry. By configuring the display device 1 in this way, it can be attached to the bottom surface of the body at the storage place of the object O and used, and can be reattached to the upper surface of the cap C at the place of use, so it can meet various needs.

[0053] As shown in FIG. 5, the peripheral wall 3 is preferably configured such that the gap G is equal to or larger than the lateral width E of the claw C2 (the straight-line distance from the outer peripheral surface of the cap C to the tip C21). The cap C provided on a bottle or the like has small claws C2, making it difficult for a finger to catch when opening and closing, and it is slippery. The display device 1 allows the user to also catch the peripheral wall 3 when catching the claw C2 with a finger, increasing the area where the finger can catch and improving the operability.

[0054] The peripheral wall 3 is preferably configured such 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. When the peripheral wall 3 and the cap C are far apart, it becomes difficult to catch both with one finger. Therefore, by configuring it in this way, the operability is ensured so that one finger can surely catch both.

[0055] As shown in FIG. 6, the display device 1 may have the center of the top plate 2 shifted from the center of the cap C. When the display device 1 is configured to have a wide display surface, from the viewpoint of being easy to balance and avoiding collisions with surrounding objects, as shown in FIG. 1(b), the center of the top plate 2 and the center of the cap C coincide, and a uniform gap G is formed around the cap C. On the other hand, when the width of the top plate 2 is relatively narrow, preferably, as shown in the figure, it is shifted to make the gap G on the claw C2 side larger to ensure the opening and closing operability of the claw C2 as described above.

[0056] <Modification Example 1 of Embodiment 1> FIG. 7 is a cross-sectional view for explaining the display device of Modification Example 1 of Embodiment 1. The display device 1 of this example has the same configuration as Embodiment 1 except for the adhesive portion 4 and exhibits the same effects. Hereinafter, the same points as those in Embodiment 1 will be appropriately omitted from the description, and the different points will be mainly described.

[0057] The adhesive portion 4 of this example has a lower surface that is an arcuate surface concave upward towards the inside. More specifically, as shown in the figure, the adhesive portion 4 has an upper surface that is a flat surface (plane) similar to the lower surface 22 of the top plate 2, and a lower surface that is concave in an arc shape upward. In other words, the adhesive portion 4 is configured to be thinner towards the inside.

[0058] The cap C of a container such as a bottle may have an upper surface that is a convex arc surface facing upward. 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 Example 2 of Embodiment 1> FIG. 8 is a diagram for explaining the display device of Modification Example 2 of Embodiment 1, and is a cross-sectional view. The display device 1 of this example has the same configuration as that of Embodiment 1 except for the lower surface 22 of the top plate 2 and the adhesive portion 4, and exhibits the same effects. Hereinafter, the same points as those of Embodiment 1 will be appropriately omitted from the description, and the different points will be mainly described.

[0060] The lower surface 22 of the top plate 2 of this example is an arc 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 shape in which the lower surface 22 is recessed in an arc shape upward. In other words, the top plate 2 is configured to have a thinner thickness toward the inside.

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

[0062] The cap C of a container such as a bottle may have an upper surface that is a convex arc surface facing upward. By configuring the lower surface 22 of the top plate 2 in this manner, the display device 1 of this example can be attached in close contact with the convex cap C even when the adhesive portion 4 has a uniform thickness.

[0063] <Modification Example 3 of Embodiment 1> FIG. 9 is a diagram for explaining the display device of Modification Example 3 of Embodiment 1, (a) is an example of a front view, and (b) is another example of a front view. The display device 1 of this example has the same configuration as that of Embodiment 1 except for the display 10, and exhibits the same effects. Hereinafter, the same points as those of Embodiment 1 will be appropriately omitted from the description, and the different points will be mainly described.

[0064] The display 10 in this example is a three-dimensional shape. The display 10 is something that evokes the object O and is provided on the upper surface 21 of the top plate 2. For example, when the object O is strawberry syrup, as an example, the display 10 can be in the three-dimensional shape of a strawberry as shown in Fig. 9(a). For example, when the object O is soy sauce, as an example, as shown in Fig. 9(b), the display 10 can be in the three-dimensional shape of soybeans.

[0065] By configuring the display tool 1 in this example so that the display 10 is more prominent, the distinctiveness can be further improved.

[0066] Note that the display tool 1 in Modification Examples 1 and 2 of the above Embodiment 1 may also be configured such that the display 10 is formed in this way.

[0067] <Embodiment 2> Figs. 10 and 11 are diagrams for explaining the display tool of Embodiment 2. 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 sectional view. Fig. 12 is a diagram showing a usage example of the display tool of Embodiment 2.

[0068] For the display tool 1 in this form, the configuration other than the upper surface 21 of the top plate 2 is the same as that in the above Embodiment 1 and has the same effects. Hereinafter, the same points as those in the above Embodiment 1 will be omitted as appropriate, and the different points will be mainly described.

[0069] As shown in the figure, for the display tool 1 in this form, the upper surface 21 of the top plate 2 is an arcuate surface that is convex upward toward the inside. The lower surface 22 of the top plate 2 is a flat surface. In other words, here, the top plate 2 is configured to be thicker as it approaches the center.

[0070] By configuring the display tool 1 in this way, even when the display 10 is displayed in the same manner as in the above Embodiment 1, the distinctiveness is further improved. For example, as shown in Fig. 10(b), a part of the display 10 can be visually recognized from the front.

[0071] In the display device 1, the wider the top plate 2 is, the better the distinctiveness is, and the distinctiveness from an oblique direction is also improved. However, there is a limit to making the top plate 2 wider. For example, if the diameter of the top plate 2 is too large with respect to the cap C, the adhesive portion with the cap C becomes relatively small and the adhesive force relatively decreases. Also, it is likely to interfere with surrounding objects. Since the display device 1 of the present embodiment changes the height without changing the planar (XZ plane) area of the top plate 2, such drawbacks can be eliminated and the distinctiveness can be improved.

[0072] <Modification Example 1 of Embodiment 2> FIG. 13 is a cross-sectional view for explaining the display device of Modification Example 1 of Embodiment 2. The display device 1 of this example has the same configuration as that of Embodiment 2 except for the adhesive portion 4 and exhibits the same effects. Hereinafter, the description of the same points as those of Embodiment 2 will be appropriately omitted, and the description will focus on the different points.

[0073] The lower surface of the adhesive portion 4 of this example is a circular arc surface that is concave upward toward the inner side. More specifically, as shown in the figure, the upper surface of the adhesive portion 4 is a flat surface similar to the lower surface 22 of the top plate 2, and the lower surface has a shape that is recessed in an arc shape upward. In other words, the adhesive portion 4 is configured to be thinner toward the inner side.

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

[0075] <Modification Example 2 of Embodiment 2> FIG. 14 is a cross-sectional view for explaining the display device of Modification Example 2 of Embodiment 2. The display device 1 of this example has the same configuration as that of Embodiment 2 except for the lower surface 22 of the top plate 2 and the adhesive portion 4 and exhibits the same effects. Hereinafter, the description of the same points as those of Embodiment 2 will be appropriately omitted, and the description will focus on the different points.

[0076] The top plate 2 of this example has a bottom surface 22 that is an arcuate surface concave upward toward the inner side. More specifically, as shown in the figure, the top plate 2 has a shape in which the upper surface 21 protrudes in an arc shape upward, and the bottom surface 22 is recessed in an arc shape upward. The radius of the arcuate surface of the bottom surface 22 may be the same as or different from the radius of the arcuate surface of the upper surface 21. When the radii of both are the same, the top plate 2 is configured with a uniform wall thickness.

[0077] As shown in the figure, the adhesive portion 4 has an upper surface that is an arcuate surface convex upward toward the inner side corresponding to the bottom surface 22 of the top plate 2, and a lower surface that is an arcuate surface concave upward toward the inner side. In other words, here, the adhesive portion 4 has a substantially uniform wall thickness and is provided in an arc shape along the bottom surface 22 of the top plate 2.

[0078] The cap C of a container such as a bottle may have an upper surface that is an arcuate surface convex upward. By configuring the bottom surface 22 of the top plate 2 in this way, the display device 1 of this example can be attached in close contact with the convex cap C even when the adhesive portion 4 has a uniform thickness.

[0079] <Modification Example 3 of Embodiment 2> FIG. 15 is a cross-sectional view for explaining the display device of Modification Example 3 of Embodiment 2. The configuration of the display device 1 of this example other than the spacer 5 and the adhesive portion 4 is the same as that of Modification Example 2 of Embodiment 2 and has the same effects. Hereinafter, the same points as those of Modification Example 2 of Embodiment 2 will be omitted as appropriate, and the different points will be mainly described.

[0080] As shown in the figure, in the display device 1 of this example, the bottom surface 22 of the top plate 2 is an arcuate surface concave upward toward the inner side. The spacer 5 is for filling the space in an arc shape in cross-sectional view formed by the bottom surface 22 of the top plate 2. The spacer 5 is configured such that the upper surface is an arcuate surface convex upward and the lower surface is a flat plane. The material of the spacer 5 is not particularly limited, and for example, an epoxy resin is used.

[0081] The adhesive part 4 is configured here to have a uniform thickness, and both the upper surface and the lower surface are flat. The adhesive part 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 part 4 to fill the cavity between the two.

[0082] The display device 1 of Modification 2 of the above Embodiment 2 is suitable for the cap C with a convex upper surface, while it is difficult to use because it does not adhere closely to the cap C with a flat upper surface. The display device 1 of this example is suitable for any cap C with a convex or flat upper surface by providing the spacer 5.

[0083] Note that the display device 1 of Modification 2 of the above Embodiment 1 may be configured to include a similar spacer 5 so that it can be applied to any cap C with a convex or flat upper surface.

[0084] <Modification 4 of Embodiment 2> FIG. 16 is a diagram for explaining the display device of Modification 4 of Embodiment 2, (a) is a cross-sectional view, and (b) is a cross-sectional view of another example. The configuration of the display device 1 of this example other than the contact part 32 of the peripheral wall 3 is the same as that of Modification 2 of the above Embodiment 2 and has the same effect. Hereinafter, the same points as those of Modification 2 of the above Embodiment 2 will be appropriately omitted from the description, and the different points will be mainly described.

[0085] As shown in the figure, the contact part 32 is provided so as to protrude inward from the inner peripheral surface of the peripheral wall 3. The contact part 32 has a lateral width sufficient to contact the outer peripheral surface of the cap C and contacts the outer peripheral surface of the cap C in the use state. The contact part 32 may have a substantially rectangular cross-section as shown in FIG. 16(a) and the lower end surface may be on the same plane as the lower end surface 31 of the peripheral wall 3, or may have a shape such as a triangle with the tip facing inward. As shown in FIG. 16(b), a plurality of rectangular portions may be provided at intervals in the cross-sectional view of the contact part 32. The contact surface of the contact part 32 may be formed in a serrated shape, a wavy shape, or the like.

[0086] The display device 1 of this example can also contact the outer peripheral surface of the cap C by providing the contact part 32 in this way, thereby improving the integrality with the cap C.

[0087] Incidentally, the contact portion 32 may be provided in the display device 1 of the second embodiment or its modification examples 1 and 3, or may be provided in the display device 1 of the first embodiment or any of its modification examples.

[0088] <Modification Example 5 of the Second Embodiment> FIG. 17 is a plan view for explaining the display device of Modification Example 5 of the second embodiment. The display device 1 in this example has the same configuration as that of Modification Example 2 of the second embodiment except for the anti-slip portion 33 and exhibits the same effects. Hereinafter, the same points as those of Modification Example 2 of the second embodiment will be omitted as appropriate, and the different points will be mainly described.

[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 plan view and is composed of, for example, a plurality of triangular shapes in plan view as shown in the drawing. The anti-slip portion 33 may be provided on a part of the outer peripheral surface of the peripheral wall 3 with an upper and lower width narrower than the height of the peripheral wall 3, or may be provided on the entire circumference. The anti-slip portion 33 may be provided along the entire length of the height of the peripheral wall 3 and reach the top plate 2 to form the outer edge of the upper surface 21.

[0090] By configuring the display device 1 in this way, the display device 1 further has an anti-slip effect. As a result, the operability is further improved, especially in the case of the screw-type cap C.

[0091] Incidentally, the anti-slip portion 33 may be provided in the display device 1 of the second embodiment or its modification examples 1, 3, and 4, or may be provided in the display device 1 of the first embodiment or any of its modification examples.

[0092] <Modification Example 6 of the Second Embodiment> FIG. 18 is a front view for explaining the display device of Modification Example 6 of the second embodiment. The display device 1 in this example has the same configuration as that of Modification Example 2 of the second embodiment except for the through hole 34 and exhibits the same effects. Hereinafter, the same points as those of Modification Example 2 of the second embodiment will be omitted as appropriate, and the different points will be mainly described.

[0093] The through-hole 34 is provided so as to penetrate the wall 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 of containers such as seasonings have pipe-shaped spouts. By including the through-hole 34, the display device 1 of this example can pass through a pipe-shaped spout and can also accommodate such a cap C.

[0094] Note that the through-hole 34 may be provided in the display device 1 of the second embodiment or its modification examples 1, 3, 4, and 5, or may be provided in the display device 1 of the first embodiment or any of its modification examples.

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

[0096] For the display device 1 of this embodiment, the configuration other than the protrusion 6 is the same as that of the first embodiment and exhibits the same effects. Hereinafter, the same points as those of the first embodiment will be appropriately omitted from the description, and the description will focus on the different points.

[0097] The top plate 2 has, here, a protrusion 6 that extends upward from a part of the edge of the upper surface 21. The protrusion 6 is configured as a chord length J corresponding to an arc of a central angle α along the edge of the upper surface as shown in the figure. The protrusion 6 is preferably provided at a position corresponding to the claw C2. As an example, the protrusion 6 is configured such that the chord length J is equal to the claw C2. As an example, the protrusion 6 is configured such 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 placing the thumb on the claw C2 from below or obliquely below and lifting the claw C2 upward. At this time, if the other fingers are placed on the upper surface of the cap C to assist, it becomes easier to open. On the other hand, the finger placed on the upper surface of the cap C may slip off and conversely become an obstacle. The display device 1 of the present embodiment is provided with the protrusion 6, thereby preventing the finger placed on the upper surface 21 of the top plate 2 from slipping off and further improving the operability of the cap C.

[0099] Note that the protrusion 6 may be provided on the display device 1 of any modification of the above-described Embodiment 1.

[0100] <Modification 1 of Embodiment 3> FIG. 21 is a diagram for explaining the 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 Embodiment 3 except for the protrusion 6 and exhibits the same effects. Hereinafter, the same points as those in Embodiment 3 will be appropriately omitted from the description, and the different points will be mainly described.

[0101] In the display device 1 of this example, the protrusion 6 is provided along the entire circumference along the edge of the upper surface 21. When assisting by placing the fingers on the upper surface of the cap C, multiple fingers may be placed, and the positions where they are placed may differ depending on the dominant hand. Also, depending on the user, the cap C may be opened by placing the claw C2 on the left or right side instead of in front. The display device 1 of this example can cope with such cases by providing the protrusion 6 along the entire circumference.

[0102] <Modification 2 of Embodiment 3> FIG. 22 is a diagram for explaining the 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 that of Modification 1 of Embodiment 3 except for the upper surface 21 of the top plate 2 and exhibits the same effects. Hereinafter, the same points as those in Modification 1 of Embodiment 3 will be appropriately omitted from the description, and the different points will be mainly described.

[0103] In the display device 1 of this example, the upper surface 21 of the top plate 2 is configured as an arcuate surface that protrudes upward more inward. When the protrusion 6 is provided along the entire circumference of the edge of the upper surface 21, while the operability of opening and closing is improved, there is a risk that the discriminability of the display 10 may decrease. By configuring the upper surface 21 of the top plate 2 in this way, the display device 1 of this example can reduce the decrease in discriminability.

[0104] <Embodiment 4> FIG. 23 is a schematic diagram for explaining the display device of Embodiment 4, where (a) is a plan view and (b) is a right side view.

[0105] The display device 1 of this embodiment is the same as that of the above Embodiment 1 in terms of the configuration except that it includes a movable plate 7 on which the display 10 is provided and a connection portion 8 for connecting the movable plate 7 to the top plate 2, and has the same effects. Hereinafter, the same points as those of the above Embodiment 1 will be appropriately omitted in the description, and the different points will be mainly described.

[0106] The movable plate 7 is connected to the upper surface 21 of the top plate 2 by the connection portion 8 so that the display angle can be changed. The movable plate 7 is preferably configured to be foldable (stacked upward) on the upper surface 21 of the top plate 2. The connection portion 8 is, for example, configured by a hinge that can rotate 90 degrees or 180 degrees. Preferably, the movable plate 7 can rotate at an arbitrary angle within 90 degrees or within 180 degrees about the axis of the connection portion 8 and can maintain the posture after rotation.

[0107] The mounting position of the connection portion 8 is not particularly limited as long as it is within the range related to the upper surface 21 of the top plate 2. The connection portion 8 is preferably attached to the edge of the top plate 2 as shown in the figure.

[0108] The display 10 is, for example, provided on the upper surface 71 of the movable plate 7 as shown in FIG. 23(a). In this case, by adjusting the angle of the movable plate 7, the display 10 can be easily discriminated from any angle in addition to the upward direction from the installation side of the connection portion 8.

[0109] The display 10 is provided, for example, on both the upper surface 21 of the top plate 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, on the side opposite to the installation side of the connection part 8.

[0110] The display 10 is provided, for example, on the upper surface 21 of the top plate 2, the upper surface 71 and the lower surface 72 of the movable plate 7. In this case, the display 10 can be easily identified from any angle, including from above, on both the installation side and the opposite side of the connection part 8.

[0111] The movable plate 7 has, for example, a flat upper surface 71 and a flat lower surface 72 as shown in the figure. One or both of the upper surface 71 and the lower surface 72 of the movable plate 7 may be an upwardly convex arc surface. By configuring it in this way, the distinctiveness can be further improved.

[0112] The movable plate 7 and the connection part 8 may be provided in the display device 1 of the above-described Embodiment 3. In this case, the connection part 8 is installed at a position where it does not interfere with the protrusion 6.

[0113] <Modification Example 1 of Embodiment 4> FIG. 24 is a schematic diagram for explaining the display device of Modification Example 1 of Embodiment 4. The display device 1 in this example has the same configuration as that of Embodiment 4 except for the movable plate 7 and the connection part 8 and exhibits the same effects. Hereinafter, the same points as those in Embodiment 4 will be appropriately omitted from the description, and the different points will be mainly described.

[0114] The display device 1 in this example includes a movable plate 7 connected to the upper surface 21 of the top plate 2 so that the display angle can be changed, in the same manner as in Embodiment 4. Here, the movable plate 7 is connected so that the angle changes three-dimensionally with respect to the top plate 2. In other words, the movable plate 7 is configured to be three-dimensionally rotatable above the top plate 2 here. As an example, the connection part 8 is configured by a universal joint, and the movable plate 7 can be rotated to an arbitrary angle and is configured to be able to hold the posture after rotation.

[0115] The mounting position of the connecting portion 8 is not particularly limited as long as it is within the range related to the upper surface 21 of the top plate 2. Preferably, the connecting portion 8 is attached to the central portion of the top plate 2 as shown in the figure.

[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 visually recognized from any angle, and the discriminability is further improved.

[0117] As an example, the upper surface 71 of the movable plate 7 is a flat surface. As an example, the upper surface 71 of the movable plate 7 is an arcuate surface convex upward.

[0118] Note that the movable plate 7 and the connecting portion 8 may be provided in the display device 1 of Modification 1 of Embodiment 3 described above.

[0119] The display device 1 according to the present invention is suitable for the object O housed in the bottle-shaped container, but the container for housing the object O is not limited to this, and other containers may be used. When the object O itself has a size and shape such that the display device 1 can be attached, the display device 1 may be attached to the object O itself.

[0120] As described above, the embodiments and modifications of the display device according to the present invention have been described. However, these are merely examples of the present invention, and the present invention is not limited thereto. The present invention includes forms in which the above and subsequent embodiments and their modifications are combined, as well as various modifications. Various additions, changes, and partial deletions are possible without departing from the conceptual ideas and spirit of the present invention derived from the content defined in the claims and their equivalents.

[0121] <Example 1 of Display Device> FIG. 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. 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 that is circular in plan view.

[0122] The display device 1 has such an anti-slip portion 33 on a part of the outer peripheral surface of the peripheral wall 3, which makes it easier to hang a finger and turn it horizontally. Also, it becomes easier to hang a finger on the anti-slip portion 33 and lift it upward. Further, by aligning the protruding direction of the anti-slip portion 33 with the direction of the cap C (the direction of the opening of the cap C), the direction of the cap C can also be indicated.

[0123] The anti-slip portion 33 is preferably formed in a substantially triangular shape in plan view as shown in the figure, is formed relatively large so that a finger can be easily hooked, and is formed such that the tip has a round shape.

[0124] In addition to such a protruding anti-slip portion 33, the display device 1 may be provided with a recessed anti-slip portion on other parts of the outer peripheral surface of the peripheral wall 3. By configuring it in this way, the rotational operability of the display device 1 is further improved.

[0125] In addition, each of the above-described configurations can be applied to the display device 1 in the illustrated example (the same applies to each of the following examples), except in cases where it is considered that it is clearly not so in principle.

[0126] <Example 2 of the display device> FIG. 26 is a diagram showing an example of the display device, (a) is a diagram showing an example of the use state, and (b) is a diagram showing another example of the cap C in (a).

[0127] As described above, the display device 1 can be removed and attached to another bottle for repeated use, for example, when the condiments or the like contained in the bottle are used up. The adhesive portion 4 has adhesiveness on both the upper surface and the lower surface as described above. From the viewpoint 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 display device 1 can adjust the ease of replacement and the adhesion by 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 be configured such that one or both of the lower surface 22 of the top plate 2 and the lower surface of the adhesive portion 4 form a concave arc surface. In this case, as shown in Fig. 26(a), when the degree of concavity of this lower surface is greater than the degree of protrusion of the upper surface of the cap C, there is a non-adhering portion (S) between the two, and the greater the difference, the larger the non-adhering portion. For example, when the radius of the arc surface of the lower surface of the adhesive portion 4 is smaller than the radius of the arc surface of the upper surface of the cap C, as shown in the figure, the peripheral vicinity portion adheres, but the central portion does not adhere, and it is relatively easy to replace. Thus, the display device 1 can be configured such that one or both of the lower surface 22 of the top plate 2 and the lower surface of the adhesive portion 4 form a concave arc surface, and the adhesion to the cap C can be adjusted according to the degree of concavity.

[0129] As shown in Fig. 26(b), even when the cap C with a flat upper surface has an R surface or a C surface on its outer periphery, this R surface or C surface adheres to the concave surface of the lower surface of the adhesive portion 4, and the other portions do not adhere to the concave surface of the adhesive portion 4, and it is relatively easy to replace.

[0130] <Example 3 of the display device> Fig. 27 is a diagram showing an example of the display device, (a) is a bottom view of an example, and (b) is a diagram showing an example of its use state. As shown in the figure, the display device 1 can be configured such that the adhesive portion 4 is formed in a donut shape with a central portion penetrating therethrough, so that there is always a non-adhering portion to the cap C. Thereby, the adhesion area between the lower surface of the adhesive portion 4 and the upper surface of the cap C is reduced, making it easier to replace.

[0131] More specifically, as shown in the figure, the display device 1 is configured such that the adhesive portion 4 is formed in a donut shape. Even when the degree of protrusion of the convex upper surface of the cap C corresponds to the degree of concavity of one or both of the lower surface 22 of the top plate 2 and the lower surface of the adhesive portion 4, a non-adhering portion to the cap C is always provided in the central portion, and the adhesion can be adjusted in a direction to reduce the adhesion for easy replacement. Note that the through hole (adhesive portion adjustment hole) in the central portion of the adhesive portion 4 is a perfect circle in the illustrated example, but other shapes such as an ellipse or a polygon may also be used.

[0132] In the display device 1 of this example, when the protrusion degree of the convex upper surface of the cap C is smaller than the recess degree of one or both of the lower surface 22 of the top plate 2 and the lower surface of the adhesive portion 4, although there may be a portion (S) that does not adhere more closely near the edge of the through hole in the central portion of the adhesive portion 4 between the two, they adhere in the vicinity of the outer periphery as in the example of Fig. 26. Further, in the display device 1 of this example, even when the protrusion degree of the convex upper surface of the cap C is larger than the recess degree of one or both of the lower surface 22 of the top plate 2 and the lower surface of the adhesive portion 4, the central portion of the upper surface of the cap C enters the through hole in the central portion of the adhesive portion 4, and the two adhere near the edge of the through hole. Thus, the display device 1 of this example is suitable for various caps C with different protrusion degrees and the adhesion can also be adjusted.

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

[0134] The display device 1 of this embodiment is mainly different from the above-described embodiment, its modified examples, and Examples 1 to 3 of the display device (hereinafter collectively referred to as "the foregoing examples") in that it includes an avoidance portion 36. Each configuration of the foregoing examples can be applied to the display device 1 of this embodiment (the same applies to the modified examples described later), except in cases where it is clearly not so in principle. Hereinafter, the explanation will focus on the different points.

[0135] The display device 1 is used by being attached to the target surface of the object O in order to display the object O, in the same manner as in the foregoing examples. The display device 1 includes a top plate 2 that is wider than the target surface of the object O, a peripheral wall 3 that extends downward in a cylindrical shape from the edge of the lower surface of the top plate 2, and an adhesive portion 4 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 other shapes.

[0136] The peripheral wall 3 has, as an example, a convex anti-slip portion (hereinafter, the convex anti-slip portion is referred to as the "first anti-slip portion") 33 that protrudes outward on the outer peripheral surface. The first anti-slip portion 33 has a substantially triangular shape, is formed relatively large so that a finger can be easily hooked, and has an overall roundness. By having the first anti-slip portion 33, the display device 1 becomes easier to rotate horizontally by hooking a finger, and also becomes easier to lift upward by hooking a finger. The first anti-slip portion 33 is disposed on the installation side of the claw C2 of the cap C. Hereinafter, the installation side of the claw C2 of the cap C is referred to as the front.

[0137] The peripheral wall 3 has, as an example, a recessed anti-slip portion (hereinafter, the recessed anti-slip portion is referred to as the "second anti-slip portion") 35 that recesses inward on the outer peripheral surface. The second anti-slip portion 35 is preferably a gently curved surface so that a finger can be easily applied. 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 at the rear facing the first anti-slip portion 33, and further two pairs are provided symmetrically on the left and right between the second anti-slip portion 35 at the rear and the first anti-slip portion 33. By applying a finger to the second anti-slip portion 35 and operating, the display device 1 has further improved rotational operability, especially in the case of a screw-type cap C.

[0138] The peripheral wall 3 has a notch-shaped avoidance portion 36 at a part of the lower end. The avoidance portion 36 has a notch shape that is notched upward, in other words, a shape in which a part of the lower end surface 31 is recessed upward. When the peripheral wall 3 has the first anti-slip portion 33, the avoidance portion 36 is provided at a position facing the first anti-slip portion 33, that is, at the rear. When the peripheral wall 3 has the second anti-slip portion 35, as shown in the illustrated example, the second anti-slip portion 35 at the rear has a shorter vertical width than the other second anti-slip portions 35 because there is the avoidance portion 36 below.

[0139] There are various hinge-type caps C having a claw C2 at the front and a hinge C1 at the rear. Some hinge C1 is provided near the upper surface of the cap C, and the distance between the hinge C1 and the upper surface is short.

[0140] As shown in Fig. 29, when the hinge C1 is disposed near the upper surface of the cap C, when the cap C is opened, the rear portion of the peripheral wall 3 may come into contact with (catch on) the lower peripheral wall C3 of the cap C, and the cap C may not open sufficiently. For example, when the cap C is prevented from opening by more than 90 degrees, the cap C may close on its own due to the weight of the cap C and the elastic force (restoring force) of the hinge C1.

[0141] In the display device 1 of this embodiment, by cutting off the portion near the lower end at the rear of the peripheral wall 3 (the portion indicated by the dashed-dotted line in the drawing) to provide the avoidance portion 36 and reducing the height of a part of the peripheral wall 3, contact with the lower peripheral wall C3 of the cap C can be avoided, and the cap C can be opened at a sufficiently large angle so that it does not close on its own.

[0142] It is also possible to respond by reducing the overall height H (see Fig. 1(b)) of the peripheral wall 3, but in some cases, it may be possible to respond more simply by partially reducing the height and providing the avoidance portion 36. Also, it is considered that providing the avoidance portion 36 can respond to a wider variety of caps C than reducing the height H.

[0143] The display device 1 is provided (shipped, etc.) in a state where, for example, the upper surface of the adhesive portion 4 is attached to the lower surface 22 of the top plate 2, and a protective release sheet (also called a release film) is attached to the lower surface 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 first necessary to remove this release sheet. Removal of this release sheet usually involves peeling it off from the outside, but in doing so, a finger may come into contact with the peripheral wall 3 and it may be difficult to peel off.

[0144] The display device 1 of this embodiment includes the avoidance portion 36 in the peripheral wall 3, thereby providing a working opening that allows a finger to reach the release sheet from this portion and facilitates the peeling operation. The avoidance portion 36 is preferably provided so as to draw a gentle curve so that discomfort can be reduced even when a finger touches it.

[0145] Furthermore, in order to improve the workability of the peeling operation, the planar shape of the peeling sheet may be different from the planar shape of the adhesive portion 4. As an example, at least a part of the outer edge of the peeling sheet may be extended and enlarged beyond the outer edge of the adhesive portion 4 to form a peeling sheet that functions as a portion to be pinched by a finger. Specific examples are shown in FIGS. 34(a) and (b). FIG. 34(b) is a view of the display device 1 as viewed from below. In this specific example, the adhesive portion 4 is an octagon with four corners removed from a substantially square shape and is sized to fit inside the lower surface 22. On the other hand, the peeling sheet 41 has a shape added to the same shape as the adhesive portion 4 and has a pinching portion 42 with a central portion at the rear extended and enlarged. The pinching portion 42 is bent downward and further bent outward and is exposed below and outside the avoiding portion 36. With such a configuration, the workability of the peeling operation can be improved. Of course, in other embodiments and modifications, a peeling sheet having a pinching portion can be provided.

[0146] <Modification Example 1 of Embodiment 5> FIG. 30 is a diagram for explaining an example of the display device of Modification Example 1 of Embodiment 5 and is a perspective view observed from above.

[0147] The display device 1 in this example is different from Embodiment 5 above mainly in that it includes a display 12 indicating the direction of the cap C (position of the operation portion or operation direction). Hereinafter, the above-mentioned displays 10 and 11 representing the object O are referred to as the first displays, and the display indicating the direction of the cap C (position of the operation portion or operation direction) of the container accommodating the object O is referred to as the second display. Hereinafter, an explanation will be centered around the second display 12.

[0148] The second display 12 here indicates the installation side of the claw C2 of the hinge-type cap C. The display device 1 in this example includes a three-dimensional second display 12. As an example, the second display 12 is three-dimensionally provided so as to protrude from the surface and be distinguishable by touch from the peripheral surface to the upper surface in the vicinity of the tip (including the tip and its vicinity) of the first anti-slip portion 33 as shown in the drawing. The shape of the second display 12 is not particularly limited and may be a tapered ridge with a slightly wider lower end and a slightly narrower upper end as shown in the drawing, or other shapes.

[0149] If the direction of the display device 1, such as the direction of the first display 10 or the protruding direction of the first anti-slip portion 33, is made to coincide with the direction of the cap C, the direction of the cap C can be visually identified, and it can be opened without having to pick up the object O again. On the other hand, when the first display 10 cannot be identified by touch, such as Braille, depending on the shape of the first anti-slip portion 33, it may not be easily identifiable by touch.

[0150] In the display device 1 of this example, by providing the second display 12 overlapping the first anti-slip portion 33, the direction of the cap C can be instantly identified by touch. Note that the display device 1 may not have the first anti-slip portion 33, and the second display 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, and the direction of the cap C can be identified by touch.

[0151] <Modification Example 2 of Embodiment 5> FIG. 31 is a diagram for explaining an example of the display device of Modification Example 2 of Embodiment 5, and is a perspective view observed from below. The illustration of the adhesive portion 4 is omitted. In the display device 1 of this example, the position where the second display 12 is arranged is different from that of Modification Example 1 of this embodiment. Hereinafter, the explanation will focus on the differences.

[0152] In this example, as shown in the figure, the second display 12 protrudes downward from the lower surface of the first anti-slip portion 33 and is provided three-dimensionally so as to be identifiable by touch on the lower surface. The specific shape of the second display 12 is not particularly limited, and it may be triangular as shown in the figure or other shapes. The display device 1 of this example has the same effect as Modification Example 1 described above.

[0153] <Modification Example 3 of Embodiment 5> FIG. 32 is a diagram for explaining an example of the display device of Modification Example 3 of Embodiment 5, where (a) is a perspective view observed from below and (b) is a right side view. In FIG. 32(a), the illustration of the adhesive portion 4 is omitted. In the display device 1 of this example, the position where the second display 12 is arranged is different from that of Modification Examples 1 and 2 of this embodiment. Hereinafter, the explanation will focus on the differences.

[0154] As shown in Fig. 32(a), the second display 12 in this example protrudes downward from the lower surface of the first anti-slip portion 33 and is provided three-dimensionally so as to be distinguishable by touch on the lower surface. The specific shape of the second display 12 is not particularly limited, and it may be a square shape as shown in the drawing, or other shapes may be used.

[0155] As shown in Fig. 32(b), the tip of the second display 12 in this example protrudes from the side of the first anti-slip portion 33, or although not shown in the drawing, the tip protrudes forward of the first anti-slip portion 33, and is further provided so as to be distinguishable by touch on the circumferential surface. Thereby, the display device 1 in this example has further improved discriminability by touch.

[0156] <Modification Example 4 of Embodiment 5> Fig. 33 is a diagram for explaining an example of the display device of Modification Example 4 of Embodiment 5, where (a) is a plan view of one example and (b) is a plan view of another example. The second display 12 in this example indicates the operation direction (operation direction) of the cap C here. Hereinafter, an explanation will be centered around the second display 12.

[0157] As described above, if the display device 1 aligns the direction of the first display 10 and the protruding direction of the first anti-slip portion 33 with the installation side of the claw C2 of the cap C, the operation position of the hinge-type cap C can be visually identified and opened without having to pick up the object O again. On the other hand, when the display device 1 is commonly applied to a screw-type cap C and a hinge-type cap C, there is a possibility that the user may not immediately determine the operation direction and may be confused.

[0158] The display device 1 of this example is provided with a second display 12 indicating the operation direction of the cap C, and solves such problems. As shown in Fig. 33(a), as an example, the display device 1 is provided with a second display 12, which is an arrow indicating the rotation direction, on the upper surface together with the first display 10, so that it can be shown that the cap C is a screw type that requires a rotation operation. As shown in Fig. 33(b), as an example, the display device 1 is provided with a second display 12, which is an arrow pointing downward, on the upper surface together with the first display 10, so that it can be shown that the cap C is a hinge type that requires a vertical opening and closing operation. Note that the second display 12 may be provided so as to cover the first anti-slip portion 33.

[0159] <Embodiment 6> Fig. 35 is a diagram for explaining the display device of Embodiment 6, (a) is an example of a cross-sectional view, and (b) is an example of a bottom view. For convenience of explanation, the illustration of the adhesive portion is omitted in Fig. 35(b).

[0160] The display device 1 of this embodiment is different from Embodiment 5 and its modified examples in that the top plate 2 is provided with an adjustment hole 23. Hereinafter, the common configurations shall refer to Embodiment 5 and its modified examples, and the description will focus on the differences.

[0161] The top plate 2 has an adjustment hole 23 (top plate adjustment hole) for adjusting the adhesion to the target surface of the object O. The adjustment hole 23 is provided substantially at the center of the lower surface 22. More specifically, the adjustment hole 23 is an open-bottomed hole that opens on the lower surface 22, is recessed in the thickness direction, and has a bottom surface in the direction approaching the upper surface 21 (upper surface 21 side). In other words, the adjustment hole 23 is a hole with a shape in which the central portion of the lower surface 22 is recessed (depressed). The adjustment hole 23 may be configured to have a uniform depth, or may be configured to be deeper inward. In other words, the bottom surface of the adjustment hole 23 may be a surface substantially parallel to the lower surface 22 (accurately, the lower surface 22 when the adjustment hole 23 is not provided), or may be a concave arc surface upward when the lower surface 22 is a plane, or may be a concave arc surface upward with different radii of curvature when the lower surface 22 is a concave arc surface upward.

[0162] When the display device 1 has a flat lower surface 22 of the top plate 2 or an arcuate surface with a large radius of curvature, and the adhesive portion 4 has a substantially uniform thickness, if the degree of protrusion of the target surface of the object O, for example, the upper surface of the cap C, is large (e.g., close to a spherical surface), the adhesive area (contact area) between the target surface and the adhesive portion 4 is small, and there is a risk that sufficient adhesive force cannot be obtained. Since the display device 1 of this embodiment has the adjustment holes 23 in the top plate 2, the central portion of the corresponding adhesive portion 4 is in a non-adhered state on the lower surface 22. When the upper surface of the cap C is attached to the lower surface of the adhesive portion 4, the adhesive portion 4, which is softer than the cap C, enters the adjustment holes 23 in accordance with the shape of the upper surface of the cap C, increasing the adhesive area. In other words, the adjustment holes 23 in the top plate 2 of this embodiment utilize the property that the adhesive portion 4 is softer (more flexible) than the top plate 2 and the cap C, and provide a space for the central portion of the adhesive portion 4 to conform to the upper surface of the cap C rather than the lower surface of the top plate 2.

[0163] In addition, when the display device 1 has a lower surface 22 of the top plate 2 that is an arcuate surface with a small radius of curvature (a large degree of curvature), and the adhesive portion 4 has a substantially uniform thickness, if the degree of protrusion of the target surface of the object O, for example, the upper surface of the cap C, is small (close to a flat surface or flat), the adhesive area (contact area) between the target surface and the adhesive portion 4 is small, and there is a risk that sufficient adhesive force cannot be obtained. Since the display device 1 of this embodiment has the adjustment holes 23 in the top plate 2, the central portion of the corresponding adhesive portion 4 is in a non-adhered state and is slightly lower than in the case where the adjustment holes 23 are not provided. Therefore, when attaching the upper surface of the cap C, depending on the degree of curvature of the target surface, the central portion of the adhesive portion 4 tends to adhere to the target surface relatively easily. In other words, the adjustment holes 23 in the top plate 2 of this embodiment can be said to prioritize the adhesion of the central portion of the adhesive portion 4 to the upper surface of the cap C over the adhesion to the lower surface 22 of the top plate 2, improving the adhesion to the target surface.

[0164] The adjustment holes 23 are not particularly limited, but from the perspective of easy adaptation, it is preferable that the shape of the opening is closer to the planar shape of the cap C. In the case of a cap C that is a perfect circle in plan view, a perfect circle shape in bottom view as shown in the illustrated example is suitable.

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

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