Specific details for implementing the invention

[0027] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the attached drawings, and the present invention is not limited or restricted by the embodiments.

[0028] In addition, the terms or words used in the present invention described below should not be interpreted as being limited to their ordinary or dictionary meanings, but should be interpreted in a meaning and concept consistent with the technical spirit of the present invention, based on the principle that the inventor can appropriately define the concept of the terms to best describe his invention.

[0029] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are merely preferred embodiments of the present invention and do not represent all technical concepts of the present invention; thus, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing this application.

[0030] FIG. 1 is a block diagram illustrating the step of forming a pattern shape according to the present invention, FIG. 2 to 6 are detailed diagrams illustrating each step according to FIG. 1, and FIG. 7 is a photograph of a tray having a pattern shape formed according to the present invention.

[0031] As described above, a tray is a household item used to transport objects such as bowls, teacups, or cups containing food, as described in the background technology of the invention, not only in homes but also in various establishments.

[0032] In particular, among trays, plastic trays are not only easy to manufacture but also have excellent cost-effectiveness, so most people these days widely use plastic trays.

[0033] However, plastic trays have the disadvantage of significantly reduced aesthetic appeal due to the formation of identical patterns resulting from mass production, as well as the disadvantage of the manufacturing process for forming various patterns being considerably cumbersome and inconvenient.

[0034] The present invention provides a method for forming a pattern on a tray and a tray having the pattern formed thereon, which allows not only identical patterns but also various desired patterns to be clearly formed on the bottom surface of a molded tray by a roll sketch method without any hassle or inconvenience.

[0035] The method for forming a pattern shape on a tray according to the present invention undergoes the following specific process.

[0036] First, a tray (100) is manufactured by molding fiberglass or synthetic resin by a known injection molding method.

[0037] In other words, the tray (100) is formed by applying heat and pressure to glass fiber or synthetic resin that is introduced into the cavity of a conventional press mold to form a tray shape, for example, a square, a circle, an ellipse, etc., and since this technique is widely known in press molding, detailed temperature and pressure ranges are omitted.

[0038] The above-described tray (100) has a bottom surface (110) and a rim (120) formed on the edge side of the bottom surface (110) so that the user can hold it without the object to be transported flowing out.

[0039] The method for forming a pattern shape, which is the core technology of the present invention, undergoes specific technical processes such as a paint layer forming step (S1), a pattern shape forming step (S2), a first drying step (S3), a non-slip coating layer forming step (S4), and a second drying step (S5).

[0040] First, the paint layer formation step (S1) forms a paint layer (10) by coating the molded tray (10) with a paint of a desired color.

[0041] In the above, the paint coating is applied evenly over the entire tray (100) with a uniform thickness by a spray method to form a paint layer (10). The thickness of the paint layer is approximately 20 to 30 μm. That is, if the thickness is 20 μm or less, it can be easily peeled off, and if it is 30 μm or more, the amount of paint used increases, raising the cost. Furthermore, if the thickness is not within the above range, the pattern shape is not properly formed, so a thickness within the above range is considered appropriate.

[0042] Next, the pattern shape forming step (S2) forms a pattern shape on the bottom surface (110) of the tray (100) by a roll sketching method using a molding roller (20) wrapped with a silicone pad (22) that is replaceable and has a desired pattern shape engraved on it, before the coated paint layer (10) is cured.

[0043] In the above, the roll sketch method utilizes silicone pads with various patterns engraved on them that are wrapped around a molding roller. Multiple silicone pads with different desired or required patterns are provided, allowing for the selection and use of the silicone pad with the required pattern or replacement as needed to form the shape. Additionally, it is acceptable to provide multiple molding rollers wrapped with the silicone pads having different patterns so that the required pattern can be selected and formed.

[0044] In other words, the formation of a pattern shape by the roll sketch method allows the pattern shape formed on the silicone pad to be formed directly on the paint layer before curing, thereby providing conditions for the pattern shape to be formed clearly and quickly on the bottom surface of the tray without going through a cumbersome or complex process.

[0045] In addition, the silicone pad forming the above pattern also has the additional condition of being usable semi-permanently by washing it again with water or chemicals.

[0046] Furthermore, the aforementioned roll sketching method can be performed manually by a skilled worker, and mechanical operation is also possible by mounting one or more rollers on a machine.

[0047] The first drying step (S3) dries the tray (100) on which a pattern is formed on the paint layer (10) so that the paint layer (10) on which the pattern is formed hardens.

[0048] In the above, the first drying method is preferably performed by drying at 60 to 70° for 35 to 45 minutes using a conveyor transfer method in a drying oven or similar drying means.

[0049] In other words, if the temperature is lower than the above, it takes a long time, and if the temperature is higher than the above, the drying time may be shortened, but due to the characteristics of the paint, the paint may run down and the pattern shape may become distorted or messed up, so it is desirable to dry within the above temperature.

[0050] If the aforementioned time is extended, the drying time of the paint may be prolonged, and if the time is too short, the paint may not cure properly; therefore, it is advisable to strictly adhere to the aforementioned time.

[0051] The non-slip coating layer formation step (S4) forms a non-slip coating layer (30) by applying a non-slip resin to the surface of the paint layer (10) in which the pattern shape has been hardened by the first drying.

[0052] In the above, it is preferable that the non-slip resin be either a silicone resin or an SF-series resin. Examples of the above types of SF-series resins include urethane resin, non-slip glossy resin, and Matte finishes are available, and various other resins with non-slip functions can also be adopted. .

[0053] The above-mentioned non-slip resin is also applied evenly with a uniform thickness to the bottom surface (110) and the rim (120) of the tray (100) on which the paint layer (10) is formed by a spray method, which is the same method as the coating of paint, to form a non-slip coating layer (30). The thickness of the above-mentioned non-slip coating layer is appropriately approximately 20 to 30 μm. That is, if the thickness is 20 μm or less, it can be easily peeled off, and if it is 30 μm or more, the amount of non-slip resin used increases, which has the disadvantage of raising the cost, so a thickness within the above-mentioned range is considered appropriate.

[0054] In other words, the non-slip coating layer applied above is intended to prevent the transported object placed on the bottom surface of the tray from sliding during transport.

[0055] The second drying step (S5) dries the formed non-slip coating layer (30) coated with the non-slip resin so that it hardens.

[0056] It is preferable that the above-mentioned second drying method also be dried at 60 to 70° for 35 to 45 minutes by means of a conveyor transfer method in a drying oven or similar drying means, which is the same as the above-mentioned first drying method.

[0057] In other words, if the temperature is lower than the above, it takes a long time, and if it is higher, the drying time may be shortened; however, since the non-slip resin may carbonize due to its characteristics, it is preferable to dry within the above temperature range.

[0058] If the aforementioned time is extended, the drying time of the non-slip resin may be prolonged, and if it is shortened, the curing of the non-slip resin may not occur properly; therefore, it is advisable to strictly adhere to the aforementioned time.

[0059] Therefore, the present invention enables the clear formation of not only identical patterns but also various desired patterns on the bottom surface of a molded tray using a roll sketch method without going through a cumbersome or complex process, thereby allowing various patterns to be formed simply, quickly, and clearly on a plastic tray without cumbersome or inconvenient.

[0060] Accordingly, since trays with various types of patterns can be supplied, trays with optimal patterns can be provided according to the user's preference. Explanation of the symbols
