Natural Rubber Baby Bottle Teat & Sealing Cap | 3D Product Design | Mechanical CAD

This project focuses on the conceptual mechanical design and 3D CAD development of a natural rubber baby bottle teat and matching sealing cap for a glass feeding bottle. The objective is to develop a functional product concept consisting of two compression-moulded rubber components: a one-piece feeding teat with an integrated threaded collar and a separate sealing cap designed to fit directly onto the bottle's glass neck. The design emphasizes practical geometry, smooth surfaces, appropriate wall thickness, ergonomic details, and manufacturing considerations for natural rubber components. Scope of Work 1. Natural Rubber Baby Bottle Teat 3D modeling of a one-piece feeding teat. Development of the teat body and integrated collar. Modeling of smooth transitions and rounded edges. Conceptual design of slow-flow and medium-flow opening variations. Consideration of wall thickness and material flexibility. Provision for a threaded connection to the glass bottle. 2. Rubber Sealing Cap 3D modeling of a flat bottle sealing cap. Conceptual threaded collar design. Rounded pull-tab development for easy handling. Smooth exterior surfaces and functional geometry. Design considerations for leak-resistant bottle closure. 3. Product Detailing Low-relief fig leaf branding detail. Rounded edges and smooth surface transitions. Component separation and organized CAD geometry. Dimensional considerations based on bottle-neck specifications. Design for Manufacturing Considerations The concept considers manufacturing requirements associated with natural rubber compression moulding, including: Wall thickness consistency. Draft angles and mould release considerations. Parting line positioning. Material shrinkage allowances. Component geometry and mould accessibility. Technical sections and dimensional drawings. Software & CAD Tools SolidWorks – 3D part modeling and mechanical design. Autodesk Fusion 360 – Product development and CAD modeling. AutoCAD – 2D technical drawings and documentation. Proposed Deliverables Editable native CAD files. STEP and STL model exports. Dimensioned 2D engineering drawings. Wall thickness and draft angle details. Sectional drawings through the collar. Component geometry and assembly documentation. Project Objective The goal is to develop a detailed and manufacturability-focused CAD concept that can be reviewed by product developers, natural rubber moulders, and relevant specialists before manufacturing. This project demonstrates my interest and capabilities in mechanical CAD design, product modeling, technical drafting, and design for manufacturing.
