Preform for liquid containers

Description

Draw 9 The item that is the subject of the design Preform for liquid containers Description of the design 1. The material is made of synthetic resin. 2. This article is a preform used when manufacturing a liquid container by blow molding. The creative design feature is that, regarding the segmented thread structure formed on the outer surface of the injection port, a specific section of the segmented thread block is removed to form a distinctly wide, threadless empty space, going beyond leaving a gap at a certain interval. By adopting such an asymmetrical, large segmented structure, the amount of resin used is reduced to increase productivity, and the waste of resources is reduced to make it environmentally friendly. Additionally, the friction area is optimized when opening and closing the lid (not shown in the drawing), resulting in a smooth operation. 3. Drawing 1 represents the overall shape of this design, Drawing 2 represents the front, Drawing 3 represents the rear, Drawing 4 represents the left side, Drawing 5 represents the right side, Drawing 6 represents the top view, and Drawing 7 represents the bottom view. 4. The parts marked with a solid line are the parts to be registered, the dotted line indicates the boundary between the parts to be registered and the parts not to be registered, and the dotted line indicates the omitted length. 5. The length omitted from the drawing is approximately 6 cm.
