More Information About 3D Model :
This description pertains to a standardized commercial packaging unit, specifically a glass bottle designed for the containment and distribution of carbonated soft drinks, currently defined by its emptied state and sealed with a metallic closure device.

### I. Classification and Context

The artifact is an example of primary beverage packaging utilized extensively within the Fast-Moving Consumer Goods (FMCG) sector. Its designation as "empty" signifies the post-consumption or post-production state where the intended liquid contents—a sugared, flavored, and carbonated soft drink (soda)—are absent. The container retains its structural integrity, transitioning from an active delivery vessel to a post-consumer residual material, typically targeted for recycling or disposal.

### II. Physical Characteristics of the Bottle

**Material:** The bottle is constructed from soda-lime glass, a rigid, non-porous, and chemically inert material composed primarily of silica (SiO₂), sodium carbonate (Na₂CO₃), and calcium carbonate (CaCO₃). This composition provides excellent barrier properties necessary to prevent gas permeability (essential for retaining carbon dioxide pressurization) and protects the contents from external contaminants. The glass is typically clear (flint) or minimally tinted (e.g., green or brown) to provide varying degrees of UV filtration, though the specified descriptor does not mandate a specific color other than transparency implied by standard glass manufacturing.

**Form Factor and Dimensions:** The vessel possesses a narrow neck finish suitable for automated sealing and subsequent controlled pouring. The body is designed to optimize volumetric capacity (e.g., 250ml, 330ml, 500ml, etc.) while maintaining sufficient wall thickness and base geometry to safely withstand typical internal pressures, which can reach up to 120 psi (approximately 8.3 bar) in highly carbonated beverages. In its empty state, the net void volume equals the nominal liquid capacity of the container.

**Condition:** The "empty" condition implies the container is ready for processing as *cullet* (recycled glass feedstock), provided the material has been cleaned of sticky residues inherent to sugary beverages.

### III. The Closure System

**Material and Type:** The bottle is sealed with a "silver metallic cap." This closure mechanism is almost universally manufactured from aluminum alloy (or, less frequently, tin-plated steel) due to its light weight, resistance to corrosion, and malleability, which allows for effective crimping or threading. The silver coloration generally indicates a natural aluminum finish or a clear protective lacquer, rather than a pigmented coating.

The cap is typically one of two designs common to carbonated beverage bottles:

1. **Crown Cap (Crimped Cap):** A fluted metallic disc with a flanged edge crimped around the glass neck ring, often utilizing a PVC or polyethylene liner to create a hermetic seal against the high internal pressure.
2. **Roll-on Pilfer Proof (ROPP) Cap:** A screw-threaded aluminum cap that is rolled onto the glass threads during sealing. ROPP caps often include an integrated tamper-evident band that separates upon initial opening.

The function of the metallic cap is critical: to ensure a complete, gas-tight seal that preserves carbonation and prevents premature oxidation or microbial contamination during the product’s shelf life.

### IV. Industrial Significance and Sustainability

The glass soda bottle represents a cornerstone of standardized global packaging, valued for the inertness of its material and its high recyclability rate. The empty bottle, provided it remains intact, is a mono-material artifact (excluding the liner in the cap) requiring minimal separation processes before recycling back into new glass products (bottle-to-bottle recycling). The combination of the glass body and metallic cap represents a mature packaging design engineered for high-speed filling lines and efficient logistics.
