Cubic receptacles or containers are extensively used in order to package various goods including foods and drinks. Ordinarily, these receptacles are formed with synthetic resin materials and labels indicating trade name or trade mark etc. are attached thereon. Conventionally, when designing receptacles of this type, there is employed a method to conduct desk work based on drafting and calculating the capacity and the amount of the resin material, thereaft-er to actually manufacture products.
A conventional process for designing such cubic receptacles is shown in FIG. 1. First, planning 1 is presented by a person who gives an order for an receptacle, and condition setting/information gathering 2 is conducted. Then, idea development 3 is carried out while repeating condition setting/information gathering 2. After narrowing down of design in regard to the receptacle form, rendering manufacture 5 in regard to the design is conducted. At this stage, presentation 6 for presenting the design to the person who has given the order is carried out. If restudying or reexamination is required, the process is repeated from the idea development 3 for a second time.
Here, in the process where the final form is determined, various components, i.e., height, width, taper and capacity constituting the form are diversely combined to reach the optimum combination. Every time these respective components are changed, a new drafting will be conducted. Such drafting works require a great deal of labor and time.
At the stage where the design has been determined, various processes, e.g., moldability studying 7, material quality studying 8, manual calculation of capacity 9, determination of dimension 10, and coloring study 11 etc. are implemented. If there is any problem, restudying will be repeated. For instance, if the capacity is not equal to a designated value, the design of the entirety of the form must be altered. Accordingly, the same procedure must be repeated from the moldability studying 7 for a second time, with the result that a considerable labor will be spent until the form is determined. When the final form is determined by repeating such studying processes, trial manufacturing of model 12 is carried out at last. This is a process to actually implement trial manufacturing of a cubic object or body as designed using a wooden model etc. Subsequently, the model trially manufactured is presented to the person who has given the order to request for studying 13. In the case where the person who has given the order has judged that the resudying is required, processes from the moldability, studying 7 to the model trial manufacturing 12 will be repeated. By the time a satisfactory model is completed, considerable labor and time are required.
When the satisfactory model is completed and the final form is determined, drafting of metal mold drawing 14 of the cubic form is carried out. Subsequently, surface design studying 15 is conducted. Namely, study on pattern design attached on the receptacle surface is carried out and a design dummy manufacturing 16 in regard to the completed pattern is conducted. Thus presentation 17 for presenting it to the person who has given the order is carried out. If restudying is required at this stage, the study on surface design 15 is repeated again. When the final determination 18 satisfactory to the person who has given the order is made, manufacturing of the receptacle 19 is carried out. A series of processes up to delivery or supply of goods 20 are thus completed.
As stated above, with the conventional method of designing cubic receptacles, studying by a person who has given the order is carried out per each process, and when restudying is required, the process of the question must be repeated for a second time. Thus, such a conventional method has the drawback that much labor and time are required.
