Description

Technical Field

[0001] This application relates to the field of cold beverage and cold chain packaging containers, specifically to a tray device. Background Technology

[0002] Most existing trays used for supporting or transporting cut ice cubes have a flat bottom structure. During loading or handling, the sharp corners of the ice cubes are prone to direct contact with the four corners of the tray bottom. When the ice cubes are dropped during transport, the impact is concentrated at the corners, which can easily cause the ice cubes to break at the corners or the tray to crack due to local stress. In addition, during the thermoforming of traditional flat bottoms, the sheet material has a long stretching path and concentrated strain at the corners, which often results in thinning at the corners, affecting the strength and service life of the tray. Utility Model Content

[0003] This application provides a tray device to improve service life.

[0004] This application provides a tray device, including at least one tray, the tray comprising:

[0005] bottom wall;

[0006] Sidewalls, arranged around the edge of the bottom wall, and forming a receiving cavity with the bottom wall for supporting an object; and,

[0007] The support part is located on the bottom wall. When the cavity supports an object, the support part supports and elevates the bottom of the object.

[0008] In some embodiments, the bottom wall has a polygonal profile, and the support is configured to be disposed around at least one corner of the bottom wall.

[0009] In some embodiments, the material used to make the support is elastic.

[0010] In some embodiments, the support includes a plurality of ribs, which are spaced apart on the bottom wall.

[0011] In some embodiments, the material used to make the ribs is elastic, and the gaps between adjacent ribs form a buffer groove.

[0012] In some embodiments, the buffer groove is configured to extend along the central axis of the bottom wall.

[0014] In some embodiments, the bottom wall has a polygonal outline, the ribs are L-shaped, and multiple ribs are respectively arranged around each corner of the bottom wall. The ribs, the bottom wall, and the side wall together form multiple clearance grooves located at each corner of the bottom wall.

[0015] In some embodiments, the corners of the bottom wall of the clearance groove are chamfered.

[0016] In some embodiments, the support portion is integrally formed with the bottom wall.

[0032] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0033] refer to Figures 1-4 Some embodiments of this application provide a tray device 100, including at least one tray 10, which includes a bottom wall 1, a side wall 2, and a support portion 3. The side wall 2 is disposed around the edge of the bottom wall 1 and forms a receiving cavity for supporting an object with the bottom wall 1. The support portion 3 is disposed on the bottom wall 1. When the receiving cavity supports an object, the support portion 3 supports and elevates the bottom of the object.

[0034] Specifically, such as Figure 2 As shown, the bottom wall 1 and the side wall 2 enclose a single-sided open receiving cavity. The opening of the receiving cavity is used to place an object. The shape of the object basically matches the shape of the receiving cavity, allowing the object to be placed relatively stably in the receiving cavity and to be basically fixed relative to the tray 10 under the constraint of the bottom wall 1 and the side wall 2. The support part 3 is located in the middle region of the bottom wall 1, and the height of the support part 3 is higher than the height of the bottom wall 1. After the object is placed, the object is raised by the support part 3, so that the edge of the object at most contacts the side wall 2 and does not contact the junction of the bottom wall 1 and the side wall 2.

[0035] It should be understood that the junction between the bottom wall 1 and the side wall 2 is a relatively weak point in the structural strength of the tray 10. By setting the support part 3, the impact damage to the edge of the object caused by shaking when the tray device 100 carries and transports the object can be reduced. This not only improves the service life of the tray device 100, but also reduces damage to the edge of the object, ensuring the reliability of the carrying and transport of the object.

[0036] In some embodiments, the tray device 100 includes six trays 10 arranged in two rows and three columns. In other embodiments not shown in the figures, the six trays 10 are arranged in a straight line.

[0037] In some embodiments, the tray 10 further includes a connecting edge, which is disposed at the top edge of the tray 10, and the connecting edge of one tray 10 is used to connect with the connecting edge of an adjacent tray 10.

[0038] refer to Figure 6 In some embodiments, the tray device 100 is used to hold ice cubes 200, with each tray 10 holding one ice cube 200. The outline of the ice cube 200 is substantially the same as the outline of the receiving cavity. The ice cube 200 is raised by the support part 3, and the edge of the ice cube 200 contacts the side wall 2 at most but does not contact the junction of the bottom wall 1 and the side wall 2. Therefore, damage to the tray 10 by the ice cube 200 can be reduced, and the integrity of the ice cube 200 can be ensured.

[0039] refer to Figure 4 In some embodiments, the bottom wall 1 has a polygonal profile, and the support portion 3 is configured to be disposed around at least one corner of the bottom wall 1.

[0040] Specifically, when the outline of the bottom wall 1 is polygonal, the corner of the bottom wall 1 is usually the weakest point in the structural strength of the tray 10. When the tray device 100 carries and transports objects, the vibrations that occur during transportation will cause the edge of the object to impact the corner of the bottom wall 1, resulting in the tray 10 breaking at this location. By having the support part 3 surround at least one corner of the bottom wall, the support part 3, the bottom wall 1, and the side wall 2 form a groove-like structure at the corner. When placing objects, the groove-like structure at the corner of the bottom wall 1 prevents the edge of the object from directly contacting the corner, thereby reducing the risk of the tray 10 breaking. At the same time, the groove-like structure can also act as a buffer. When the tray 10 falls during transportation, the groove-like structure reduces the direct impact of external forces on the corner of the object, reducing damage to the object.

[0041] In some embodiments, the material used to make the support portion 3 is elastic.

[0042] By using a material with a certain degree of elasticity, when the tray device 100 shakes during the process of carrying and transporting objects, the support part 3 can be compressed to play a buffering role, protect the objects, and improve the safety and reliability of the transport.

[0043] Still referencing Figure 4 In some embodiments, the support portion 3 includes a plurality of ribs 31, which are spaced apart on the bottom wall 1.

[0044] Specifically, the multiple raised ribs 31 spaced apart on the bottom wall 1 ensures sufficient contact area between the ribs and the object, improving the stability of the support. Furthermore, the multiple raised ribs 31, in conjunction with the bottom wall 1, create a concave-convex structure at the bottom of the tray 10. Therefore, when the object is ice, the ice cube 200 can make partial contact with the bottom of the tray 10, reducing the adhesion of the ice cube 200 to the tray 10 after prolonged freezing and making it easier to remove the ice cube from the tray 10.

[0045] In some embodiments, the height of the rib 31 is set in the range of 1~8mm, and the width is set in the range of 3~15mm.

[0046] In some embodiments, the material of the rib 31 is elastic, and the gap between adjacent ribs 31 forms a buffer groove 32.

[0047] The gap between adjacent ribs 31 can provide deformation space for the ribs 31. When the tray device 100 shakes, the ribs 31 can undergo compressive deformation, disperse the impact load, and improve the drop buffering capacity.

[0048] In some embodiments, the depth of the buffer groove 32 is set in the range of 1 to 8 mm. It should be understood that the depth of the buffer groove 32 is the same as the height of the rib 31.

[0049] In some embodiments, the buffer groove 32 is configured to extend along the central axis of the bottom wall.

[0050] Specifically, the multiple ribs 31 are symmetrically distributed about the central axis of the bottom wall 1, so that the buffer groove 32 extends along the central axis of the bottom wall 1. In this way, when an object is placed, the position of the object supported by the ribs 31 is symmetrical, which can make the object be placed more evenly and stably in the receiving cavity, reducing the possibility of the object tilting. It should be understood that when the object is tilted, the edge of the object is closer to the corner of the bottom wall 1 than when it is even. By making the buffer groove 32 extend along the central axis of the bottom wall 1, the risk of the object tilting can be reduced, thereby reducing the risk of the edge of the object hitting the corner of the bottom wall 1 and breaking the tray 10.

[0051] refer to Figure 1 and 4 In some embodiments, the buffer groove 32 formed by the gaps between the multiple ribs 31 has a cross structure.

[0052] Specifically, the bottom wall 1 has a square outline, and the two extended sides of the cross-shaped buffer groove 32 are perpendicular to each other and extend along the two central axes of the square bottom wall 1. This layout allows multiple ribs 31 to be evenly distributed around the center of the bottom wall 1, which can support the object more stably. When shaking or impact occurs, the cross-shaped buffer groove 32 can undergo relatively balanced compression deformation, thereby playing a better role in buffering and unloading.

[0053] In some embodiments, the bottom wall 1 has a polygonal outline, the ribs 31 are L-shaped, and multiple ribs 31 are respectively arranged around each corner of the bottom wall 1. The ribs 31, the bottom wall 1, and the side wall 2 together form multiple clearance grooves 33 located at each corner of the bottom wall 1.

[0054] Specifically, the bottom wall 1 has a rectangular outline, the spatial outline of the receiving cavity is approximately cubic, the tray 10 is used to hold objects with a cubic structure (e.g., ice cube 200), and the support part 3 includes four protruding ribs 31, which are respectively arranged around the four corners of the bottom wall 1. Taking one of the protruding ribs 31 as an example, the protruding rib 31 has a first segment 311 extending along a first direction X and a second segment 312 extending along a second direction Y. The first direction X is perpendicular to the second direction Y. The first end of the first segment 311 is connected to the first end of the second segment 312. The second end of the first segment 311 and the second end of the second segment 312 extend to connect with two adjacent side walls, so that the protruding ribs 31, the bottom wall 1 and the side walls 2 together enclose a rectangular clearance groove 33 at the corner of the bottom wall 1. The four protruding ribs 31 form four clearance grooves 33 respectively. After the object is placed in the receiving cavity, the four corners of the bottom of the object are separated from the four corners of the bottom wall 1 by the four clearance grooves 33 respectively, so as to avoid the four corners of the bottom of the object from directly contacting the four corners of the bottom wall 1, thereby reducing the risk of the tray 10 breaking and protecting the object to a certain extent.

[0055] In some embodiments, a chamfer is provided at the junction of the first segment 311 and the second segment 312. By providing the chamfer, the first segment 311 and the second segment 312 can be prevented from being directly connected at right angles, thereby reducing scratches or even damage to the object when supporting it.

[0056] In some embodiments, the buffer groove 32 is provided with a chamfer at the junction of its end in the extending direction and the side wall 2 of the tray 10. By providing the chamfer here, the material of the tray 10 can be stretched more evenly at the junction of the end of the buffer groove 32 and the side wall 2, thereby reducing the probability of thinning and film breakage.

[0057] In some embodiments, the first direction X is configured as the length direction of the tray device 100, and the second direction Y is configured as the width direction of the tray device 100.

[0058] In some embodiments, the corners of the bottom wall of the clearance groove 33 are chamfered.

[0059] Specifically, the bottom wall of the clearance groove 33 is on the same plane as the bottom wall 1 of the tray 10. The chamfering at each corner of the bottom wall of the groove can reduce stress concentration at the corners and reduce the likelihood of the tray 10 cracking. Moreover, the chamfering can make the material of the tray 10 stretch more evenly at each corner and at the junction of the side wall 2 and the bottom wall 1, reducing the probability of thinning and film breakage, and improving product consistency and yield.

[0060] In some embodiments, by providing chamfers at each corner of the bottom wall of the clearance groove 33, forming a triangular cross-section at the chamfer, the bottom wall of the clearance groove 33 is made into a regular octagon. In other embodiments, the profile of the chamfer is adjusted so that the bottom wall of the clearance groove 33 is any one of a triangle, a quadrilateral, and a trapezoid.

[0061] In some embodiments, the support portion 3 is integrally formed with the bottom wall 1. Specifically, the support portion 3 and the bottom wall 1 are integrally formed using vacuum, positive pressure, or positive and negative pressure molding processes, that is, the bottom of the tray 10 is an integral concave-convex bottom structure. This has the advantage of facilitating processing and manufacturing, and improving the stability of the connection between the support portion 3 or the rib 31 and the bottom wall 1.

[0062] In some embodiments, the support 3, bottom wall 1, and side wall 2 are integrally formed by vacuum, positive pressure, or positive and negative pressure molding processes.

[0063] In some embodiments, the tray 10 is made of PET, PP, PS or a composite sheet thereof, with a thickness between 0.7 and 1.5 mm.

[0064] The structure of a tray device 100 according to an embodiment of this application is briefly described below. See also: Figures 1-6 The tray device 100 includes six trays 10 arranged in a two-row, three-column configuration. Each tray 10 includes a square base wall 1 and four side walls 2 surrounding its four edges. The base wall 1 and the four side walls 2 form an open receiving cavity. The tray 10 holds ice cubes 200, which are placed in the tray 10 through the opening of the receiving cavity. The base wall 1 has four protruding ribs 31, each L-shaped with a first segment 311 and a second segment 312 perpendicular to each other. The first end of the first segment 311 connects to the second end of the second segment 312, and the second ends of the first segment 311 and the second segments 312 connect to two adjacent side walls 2. The four protruding ribs 31 surround the four corners of the base wall 1, forming a clearance groove 33 at each corner with the base wall 1 and the side walls 2. The gaps between the four protruding ribs 31 also form a cross-shaped buffer groove 32.

[0065] The tray 10 is made of PP sheet, with a bottom wall 1 and side walls 2 having a thickness of 1mm, and the rib 31 having a height of 3mm and a width of 5mm. The support part 3, bottom wall 1, and side walls 2 are integrally molded using vacuum, positive pressure, or positive and negative pressure molding processes. Figure 5As shown, the bottom of the tray 10 has a concave-convex bottom structure. From the inside of the tray 10, the rib 31 is a protruding structure set on the bottom wall 1, and the buffer groove 32 and the clearance groove 33 are recessed structures relative to the rib 31. From the outside of the tray 10, the rib 31 is a recessed structure set on the outside of the bottom wall 1, and the buffer groove 32 and the clearance groove 33 are protruding structures relative to each other.

[0066] When placing ice cubes 200, the four ribs 31 collectively support the bottom of the ice cubes 200, raising them by 3mm. This ensures that the sharp corners of the ice cubes 200 at most contact the four side walls 2 of the tray 10, but not the junction between the bottom wall 1 and the side walls 2, especially the four corners of the bottom wall 1. This reduces the risk of the ice cubes 200 colliding with the corners of the bottom wall 1 during transportation, thus preventing the tray 10 from breaking. Furthermore, the ribs 31 have a certain degree of elasticity, and the buffer grooves 32 formed by the gaps between the ribs 31 can undergo compressive deformation, acting as a buffer during the transportation of the ice cubes 200 and reducing the probability of damage. Simultaneously, based on the avoidance grooves 33, the impact of external forces on the sharp corners of the ice cubes 200 during drops during transportation is reduced, significantly lowering the corner breakage rate of the ice cubes 200. In addition, the uneven bottom structure of the tray 10 allows the ice cubes 200 to make partial contact with the bottom of the tray 10, reducing the adhesion of the ice cubes 200 to the tray 10 after long-term freezing, and making it easier to remove the ice cubes from the tray 10.

[0067] Based on the embodiments disclosed above, in the absence of explicit denial or conflict, the technical features of one embodiment may be advantageously combined with one or more other embodiments.
