Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, when the trays are stacked in a state where the article is stored in an incorrect posture different from the normal posture with respect to the storage portion, there is a risk that the article may be damaged or the stacked trays may tilt.

[0005] The present invention has been made to solve the above-exemplified problems and the like, and an object thereof is to provide a tray capable of suppressing storage of an article in an incorrect posture.

Means for Solving the Problems

[0006] Hereinafter, each means suitable for solving the above problems and the like will be described separately. In addition, the effects and the like peculiar to the corresponding means will be appended as necessary.

[0007] Means 1. A tray having a storage section capable of accommodating articles, comprising a base section and a cylindrical section that protrudes from the base section and opens towards its tip, The storage section is configured to accommodate the article in a position where the cylindrical portion opens downwards, The tray is characterized in that the storage section includes a mis-storage prevention section which is inserted inside the cylindrical section when the article is stored in the storage section in the correct orientation, and which contacts the article when the article is stored in the storage section in an incorrect orientation different from the correct orientation, and supports the article in an inclined position in which the height direction of the article in the incorrect orientation is inclined with respect to the height direction of the article when the article is stored in the storage section in the correct orientation.

[0008] According to method 1, if an item is placed in the storage compartment in the wrong orientation, the item in the wrong orientation is supported in an inclined position (the height direction of the item placed in the wrong orientation is tilted relative to the height direction of an item placed in the correct orientation, for example, the vertical direction). This makes it easier for workers to recognize that an item is placed in the wrong orientation. Consequently, it is possible to prevent situations where the storage state of an item becomes unstable due to the item being placed in the wrong orientation, causing the item to be displaced and damaged when the tray is transported, or where items or trays placed in the wrong orientation are damaged or the stacked trays tilt when trays containing items are stacked on top of each other.

[0009] Means 2. The housing portion is provided with a bottom portion that contacts and supports the cylindrical portion of the article in the normal position, The aforementioned mis-accommodation prevention portion protrudes upward from the bottom and is integrally formed with the bottom. The tray according to means 1, wherein the mis-storage prevention section comprises a contact section that can come into contact with the article stored in the storage section in the wrong orientation, and the top of the contact section, which is located at the uppermost position, is positioned away from the center of the storage section in a plan view.

[0010] According to method 2, if an item is stored in the storage compartment in the wrong orientation, the item can be tilted in a predetermined direction rather than randomly. Therefore, it is possible to make it easier for workers to recognize that an item is stored in the wrong orientation, and to prevent the item from tilting in the direction that is not desired.

[0011] Means 3. The contact portion of the mis-accommodation prevention portion has an inclined portion that slopes downward from the end on which the top portion is provided toward the opposite end, The tray according to means 2, characterized in that the lower end of the inclined portion is located on the opposite side of the top portion from the center of the storage portion in a plan view.

[0012] According to method 3, the article in an inclined position can be supported more stably by the mis-storage prevention section. In addition, the article in an inclined position can be guided relatively stably toward the downstream side of the inclined section (until it reaches a position where displacement is restricted).

[0013] Means 4. The housing section is, A restricting portion that contacts the upper side of the article in the inclined position and is capable of restricting its displacement toward the outer periphery of the housing portion, The tray according to means 3, characterized in that it comprises an interference avoidance portion capable of accommodating a part of the lower surface of the article when the article is in the inclined position and its displacement is restricted by the restricting portion.

[0014] According to means 4, if an article is stored in an incorrect orientation and becomes inclined (displaced downward as guided by the inclined portion), contact between the lower edge of the article and the bottom of the storage portion can be avoided, thus preventing the bottom from being scraped and adhering to the article due to contact. It may also be stated that "the article stored in the storage portion in the correct orientation is configured not to be stored in the interference avoidance portion."

[0015] Means 5. Equipped with multiple of the aforementioned housing sections, A positioning recess provided on the lower surface side of the housing portion, It is provided between the accommodating portions and includes a positioning convex portion that protrudes upward. When the upper tray is placed in a direction rotated by a specific angle horizontally with respect to the lower tray, the positioning convex portion of the lower tray is positioned inside the positioning concave portion of the upper tray, and it is a configuration that enables a stacked state in which the horizontal displacement between the upper and lower trays is restricted. The tray according to means 3 or 4, characterized in that it includes a downward protrusion that protrudes downward from the inclined portion and can abut on the upper surface side of the positioning convex portion of the lower tray in the stacked state.

[0016] According to means 5, when installing a tray on the upper side of a tray containing articles and performing the operation of accommodating articles in the upper tray, when the articles are accommodated in an incorrect posture, it is possible to suppress a situation where the anti-misaccommodation portion (inclined portion) is deformed downward by the articles. Therefore, the shape of the anti-misaccommodation portion is protected, and the anti-misaccommodation portion more surely exhibits the effect of making the articles accommodated in an incorrect posture into an inclined posture.

[0018] An embodiment will be described below with reference to the drawings. As shown in Figure 1, the tray 1 comprises a base portion 2 which is substantially rectangular in plan view, an edge wall portion 3 which extends downward from the outer peripheral edge of the base portion 2, and a storage portion 4 which is formed by recessing the base portion 2 downward and is capable of accommodating articles 31. In this embodiment, the storage portion 4 is composed of rows of two storage portions 4 which are spaced a predetermined distance apart from each other in the short width direction of the tray 1, and three such rows are formed in the long width direction of the tray 1. The storage portion 4 of the middle row is positioned with a half-pitch offset in the short width direction of the tray 1 relative to the storage portion 4 of the end row. Furthermore, the tray 1 in this embodiment is integrally formed from polyethylene by vacuum forming.

[0019] As shown in Figures 5 and 6, the article 31 comprises a disc-shaped base portion 32, a cylindrical first cylindrical portion 33 protruding from one side (front) of the base portion 32, and a cylindrical second cylindrical portion 34 protruding from the opposite side (back) of the base portion 32. The central axis of the first cylindrical portion 33 is located on the extension of the central axis of the base portion 32, and it is located on the inner circumference side of the base portion 32, rather than on the outer peripheral edge of the base portion 32 (its diameter is smaller than the outer diameter of the base portion 32). A space 35 is formed inside the first cylindrical portion 33, and an opening 36 is provided at the tip end of the first cylindrical portion 33. The central axis of the second cylindrical portion 34 is located on the extension of the central axis of the base portion 32, and it is located on the inner circumference side of the base portion 32, rather than on the first cylindrical portion 33 (its diameter is smaller than the first cylindrical portion 33). In this embodiment, the first cylindrical portion 33 constitutes the "cylindrical portion".

[0020] As shown in Figures 2 to 4, the storage section 4 comprises a lower bottom section 11 that is roughly annular in plan view, a lower wall section 12 that extends upward from the outer peripheral edge of the lower bottom section 11, an upper bottom section 13 that extends outward from the upper edge of the lower wall section 12 towards the outer peripheral side of the storage section 4, and an upper wall section 14 that extends upward from the outer peripheral edge of the upper bottom section 13, with the upper edge of the upper wall section 14 connected to the base section 2. As shown in Figure 7, the storage section 4 of this embodiment is configured to accommodate an article 31 in a position where the first cylindrical section 33 (space section 35) opens downward as the normal position (see storage section 4X in Figure 1). When the article 31 is stored in the storage section 4 in the normal position, the peripheral edge of the opening 36 of the first cylindrical section 33, which corresponds to the lower end of the article 31 in the normal position, abuts against the lower bottom section 11, supporting the article 31 so that its central axis extends in a roughly vertical direction. Furthermore, the lower surface (front surface) of the base portion 32 of the article 31 in its normal orientation is supported by contact with the upper bottom portion 13. In addition, when the article 31 is housed in the housing portion 4 in its normal orientation, the lower wall portion 12 is configured to be able to contact the outer surface of the first cylindrical portion 33 if the article 31 is displaced in a predetermined horizontal direction, thereby restricting further displacement of the article 31 in the predetermined horizontal direction. It should be noted that when the article 31 is housed in the housing portion 4 in its normal orientation, only one of the first cylindrical portion 33 and the base portion 32 may be supported by contact with the lower bottom portion 11 and the upper bottom portion 13 of the housing portion 4.

[0021] Furthermore, as shown in Figures 2 to 4, the storage section 4 is equipped with a mis-storage prevention section 15 that protrudes upward from the lower bottom section 11 on the inner circumference side of the lower bottom section 11. The mis-storage prevention section 15 comprises a peripheral wall section 16 extending upward from the inner peripheral edge of the lower bottom section 11 and a contact section 17 provided to close the space between the upper edges of the peripheral wall section 16. The uppermost apex 18 (see Figure 4) of the contact section 17 is located away from the center of the storage section 4 in a plan view, and the entire section slopes downward from the end where the apex 18 is located toward the opposite end. Furthermore, the lower end of the inclined contact section 17 is located on the opposite side of the apex 18 from the center of the storage section 4 in a plan view, and the contact section 17 has a continuous surface from the apex 18 to the lower end. In this embodiment, almost the entire contact section 17 (excluding the downward projection 25 described later) constitutes an inclined section. Furthermore, the top portion 18 of the mis-storage prevention section 15 is located below the bottom portion 13 of the upper section.

[0022] Furthermore, the outer diameter of the mis-storage prevention section 15 (contact section 17) is smaller than the inner diameter of the first cylindrical section 33. Therefore, as shown in Figure 7, when an article 31 in its normal orientation is stored in the storage section 4, the mis-storage prevention section 15 is inserted into the space 35 (inside the first cylindrical section 33) through the opening 36. On the other hand, the outer diameter of the mis-storage prevention section 15 (contact section 17) is larger than the outer diameter of the second cylindrical section 34. Therefore, as shown in Figure 8, when an article 31 in its normal orientation is rotated 180 degrees vertically (hereinafter referred to as the "incorrect orientation") and stored in the storage section 4, the contact section 17 of the mis-storage prevention section 15 comes into contact with the second cylindrical section 34 of the article 31. In this case, the contact portion 17 is inclined with respect to the lower bottom portion 11, etc., so the mis-storage prevention portion 15 (contact portion 17) supports the article 31 in an inclined position where the height direction (central axis direction) of the article 31 in the incorrect orientation is inclined with respect to the height direction (central axis direction) of the article 31 when the article 31 is stored in the storage portion 4 in the correct orientation (see storage portion 4Y in Figure 1). In this embodiment, the inclination angle of the height direction of the article 31 in the inclined position with respect to the height direction (approximately vertical direction in this example) of the article 31 in the correct orientation is approximately 8 degrees. Also, in this embodiment, the contact portions 17 of all storage portions 4 are inclined in the same direction.

[0023] Furthermore, the shape of the storage section 4 in plan view is formed to match the outer shape of the article 31 that is stored in the storage section 4 in its normal orientation. In other words, in this embodiment, the shape of the storage section 4 in plan view is a circle that is slightly larger than the base portion 32 of the article 31. For example, if the article 31 in its normal orientation is rotated 90 degrees around a predetermined horizontal axis, it is clear that the orientation of the article 31 will not match that of the storage section 4. For this reason, the "incorrect orientation" of the article 31 in this embodiment basically refers to the orientation of the article 31 rotated 180 degrees vertically (inverted orientation).

[0024] Furthermore, as shown in Figure 8, in this embodiment, if the article 31 is placed in the storage section 4 in an incorrect orientation, the upper wall portion 14 is configured to contact the upper side of the article 31 in an inclined position, thereby restricting its displacement toward the outer periphery of the storage section 4. In this embodiment, the upper wall portion 14 constitutes the restricting portion. In addition, the upper wall portion 14 extends upward from the upper bottom portion 13 toward the outer periphery of the storage section 4, with a slight incline.

[0025] In addition, the storage section 4 is equipped with an interference avoidance section 19 that can accommodate a portion of the lower surface (the part visible when viewed from below) of the article 31 when the article 31 is in an inclined position and in contact with the upper wall section 14 (a state in which displacement is restricted by the upper wall section 14). In this embodiment, the interference avoidance section 19 is constructed by lowering the outer peripheral portion of the upper bottom section 13 by one step, so that when the article 31 is in an inclined position and in contact with the upper wall section 14, the edge of the lower surface (back surface) of the base section 32 is accommodated in the interference avoidance section 19. Note that, as shown in Figure 7, when the article 31 is stored in the storage section 4 in the normal position, it is not accommodated in the interference avoidance section 19, and the edge of the lower surface (front surface) of the base section 32 is located above the interference avoidance section 19. In addition, as shown in Figure 8, when the article 31 is in an inclined position and its displacement is restricted by the upper wall portion 14, the lower edge of the second cylindrical portion 34 is positioned within the range above the contact portion 17 (it does not protrude outward beyond the outer peripheral edge of the contact portion 17).

[0026] Furthermore, as shown in Figure 10, the tray 1 is provided with positioning recesses 21 on the lower side of each storage section 4. In addition, as shown in Figure 1, etc., the tray 1 is provided between the storage sections 4, protruding upward, and has a roughly disc shape (a roughly cylindrical shape with a low height and a closed upper side) with a flat upper surface, and a positioning projection 22. As shown in Figure 2, etc., the lower bottom section 11 of the storage section 4 in this embodiment is provided with a support section 23 that abuts against and supports the lower edge of the first cylindrical section 33 of the article 31 stored in the storage section 4 in the normal position, and a bulge section 24 that bulges downward from the support section 23. In a plan view, the support section 23 extends in all directions from the interference avoidance section 19 and is connected to the lower wall section 12, and the portion between the support sections 23 is the bulge section 24. Due to the configuration of the lower bottom section 11, as shown in Figure 10, the portion on the lower side of the lower bottom section 11 surrounded by the four roughly arc-shaped bulges 24 is the positioning recess 21. Then, as shown in Figure 9, when the upper tray 1 is placed on the lower tray 1 rotated 180 degrees horizontally, the positioning protrusion 22 of the lower tray 1 is positioned inside the positioning recess 21 of the upper tray 1, as shown in Figures 11 and 12, resulting in a stacked state in which horizontal misalignment of the upper and lower trays 1 is restricted.

[0027] Furthermore, as shown in Figure 11, etc., the tray 1 is provided with a downward projection 25 that protrudes downward from the contact portion 17 (inclined portion) and can abut against the upper surface of the positioning projection 22 of the lower tray 1 when stacked. The downward projection 25 is formed by creating a circular, bottomed recess in a plan view, with a diameter smaller than the outer diameter of the second cylindrical portion 34, in a range including the central part of the contact portion 17, and the lower surface that abuts against the upper surface of the positioning projection 22 extends substantially horizontally so as to be substantially parallel to the upper surface of the positioning projection 22.

[0028] In this embodiment, when the tray 1 is placed on a surface such as the floor, the lower surface of the bulging portion 24 is in contact with the surface and supported. Also, even when the trays 1 are stacked, the lower surface of the bulging portion 24 of the upper tray 1 abuts against the upper surface of the base portion 2 of the lower tray 1 and is supported. In addition, the area from at least the portion of the lower wall portion 12 connected to the support portion 23 to the upper edge of the lower wall portion 12 is a portion that is partially widened on the outer circumference of the storage portion 4, and this portion is configured to avoid contact with the first cylindrical portion 33 of the article 31 stored in the storage portion 4 in the normal position.

[0029] As described in detail above, according to this embodiment, if an article 31 is placed in the storage section 4 in an incorrect orientation, the article 31 in the incorrect orientation is supported in an inclined position (the height direction of the article 31 placed in an incorrect orientation is inclined with respect to the height direction of an article 31 placed in a normal orientation, which in this example is approximately vertical). This makes it easier for workers to recognize that an article 31 is placed in an incorrect orientation. Consequently, it is possible to prevent situations where the storage state of the article 31 becomes unstable due to the article 31 being placed in an incorrect orientation, causing the article 31 to be displaced and damaged when the tray 1 is transported, or where the article 31 placed in an incorrect orientation or the tray 1 is damaged or the stacked tray 1 is tilted when the trays 1 containing the articles 31 are stacked.

[0030] Furthermore, of the mis-storage prevention section 15, the contact section 17 that can come into contact with the article 31 stored in the storage section 4 in the wrong orientation has its uppermost apex 18 positioned away from the center of the storage section 4 in a plan view. Therefore, when the article 31 is stored in the storage section 4 in the wrong orientation, the article 31 can be tilted in a predetermined direction rather than randomly. Consequently, it is possible to make it easier for the worker to recognize that the article 31 is stored in the wrong orientation, and to prevent the article 31 from tilting in the direction that is not desired.

[0031] Furthermore, the contact portion 17 of the mis-storage prevention section 15 slopes downward from the end where the top portion 18 is provided toward the opposite end, and the lower end of the contact portion 17 is located on the opposite side of the top portion 18, with the center of the storage section 4 in a plan view. As a result, the mis-storage prevention section 15 can support the inclined article 31 more stably. In addition, the inclined article 31 can be guided relatively stably with the downstream side of the contact portion 17 toward the upper side of the article 31 until the upper part of the side of the article 31 comes into contact with the upper wall portion 14 and further displacement is restricted.

[0032] In addition, the storage section 4 is equipped with an interference avoidance section 19 that can accommodate a portion of the lower surface of the article 31 (in this example, the base section 32) when the article 31 is in an inclined position and the upper side of the article 31 is in contact with the upper wall section 14. Therefore, if the article 31 is stored in an incorrect position and becomes inclined (displaced downward as guided by the inclined contact section 17), contact between the lower edge of the article 31 (base section 32) and the bottom of the storage section 4 (upper bottom section 13) can be avoided, and a situation in which the upper bottom section 13 is worn down and adheres to the article 31 due to contact can be avoided. Furthermore, the upper wall section 14 that constitutes the restricting section extends upward and inclined toward the outer circumference of the storage section 4. Therefore, a situation in which the upper wall section 14 is worn down when it comes into contact with the inclined article 31 can be further suppressed.

[0033] Furthermore, tray 1 is equipped with a positioning recess 21 provided on the lower side of the storage section 4 and a positioning projection 22 provided between the storage sections 4 and projecting upward. When the trays 1 are stacked, the positioning projection 22 of the lower tray 1 is positioned inside the positioning recess 21 of the upper tray 1. In addition, tray 1 is equipped with a downward projection 25 that projects downward from the contact section 17 and can contact the upper side of the positioning projection 22 of the lower tray 1 when stacked. Therefore, when performing an operation such as placing tray 1 above tray 1 containing articles 31 and then placing articles 31 into the upper tray 1, it is possible to prevent the mis-storage prevention section 15 (contact section 17) from being deformed downward by the articles 31 if the articles 31 are stored in the wrong orientation. Accordingly, the shape of the mis-storage prevention section 15 is protected, and the effect of the mis-storage prevention section 15 in tilting the articles 31 stored in the wrong orientation is more reliably achieved.

[0034] Furthermore, the embodiment is not limited to the description above, and may be implemented as follows, for example. Of course, other applications and modifications not exemplified below are also possible.

[0035] (a) In the above embodiment, the number of storage sections 4 and their arrangement are not particularly limited, and for example, there may be seven or more storage sections 4, or five or fewer. Furthermore, the articles to be stored in the tray 1 only need to have a shape comprising a base portion and a cylindrical portion protruding from the base portion, and can be materialized as a tray for storing such articles. For example, it is also possible to omit the second cylindrical portion 34 of the above embodiment. Furthermore, as shown in Figure 13, for example, in a storage section 41 capable of accommodating an article 51 comprising a disc-shaped base section 52 and a cylindrical tubular section 53 protruding from the outer peripheral edge of the base section 52 and opening on the opposite side from the base section 52, if the article 51 is stored in the storage section 41 in an incorrect orientation (with the tubular section 53 opening upward), and is supported in an inclined position by the mis-storage prevention section 42, and the upper side of the article 51 abuts against a wall section 44 extending upward from the outer peripheral edge of the bottom section 43 of the storage section 41, thereby restricting further displacement, an interference avoidance section 45 capable of accommodating the edge of the lower surface side (base section 52) of the article 51 may be provided (between the support sections 46 that support the article 51 in the correct orientation on the bottom section 43) (the article 51 in the inclined position is configured not to come into contact with the support sections 46). Furthermore, in the above embodiment, if, for example, the diameter of the second cylindrical portion 34 is made larger, or the upper wall portion 14 is positioned further outward from the outer circumference of the housing portion 4, and the article 31 is in an inclined position and in contact with the upper wall portion 14, thereby restricting its displacement, and the second cylindrical portion 34 protrudes further outward from the outer circumference of the housing portion 4 than the outer edge of the contact portion 17, it is desirable to provide an interference avoidance portion 19 on the lower bottom portion 11 to avoid contact between the second cylindrical portion 34 and the lower bottom portion 11. In addition, the interference avoidance portion 19 can also be made up of a hole rather than a recess.

[0036] Furthermore, the inclination angle of the inclined article 31 in the height direction relative to the article 31 in the normal orientation may be set within the range of 3 to 45 degrees. Here, from the viewpoint of suppressing situations such as the article 31 being forcefully displaced in a predetermined direction by the mis-storage prevention part 15 (inclination of the contact part 17) when the article 31 is stored in the storage part 4 in an incorrect orientation, it is desirable that the inclination angle be as small as possible (for example, 15 degrees or less). From the viewpoint of making it easy to recognize that the article 31 is stored in the storage part 4 in an incorrect orientation, it is desirable that the inclination angle not be too small (for example, 5 degrees or more).

[0037] (b) In the above embodiment, the shape of the mis-storage prevention section 15 is not particularly limited. For example, the mis-storage section 4 may be formed by a projection that protrudes upward from the inner circumference of the lower bottom section 11 and from a position away from the center of the storage section 4. In addition, in the above embodiment, even if an article 31 is stored in any of the storage sections 4 in the wrong orientation, the articles 31 that are in an inclined position are all configured to tilt in the same direction. However, they may be configured to tilt in different directions. Furthermore, the shape of the upper wall section 14 (regulating section) may be configured so that it cannot come into contact with the upper side of the article 31 when it is inclined in a different direction from the article 31 that is in an inclined position.

[0038] (c) In the above embodiment, the tray 1 is made of polyethylene, but it may also be made of other resin materials such as polypropylene, PET, polyamide, or other polyolefins. Also, although the tray 1 in the above embodiment is made by vacuum forming, it may also be formed by other methods such as compression molding or injection molding. [Explanation of symbols]
