Core Concepts and Key Technologies

Double-Wall Vacuum Insulation

At the core of the 15oz beer cup is double-wall vacuum insulation, a technology designed to minimize heat transfer and maintain beverage temperature.

Vacuum Layer: The space between the inner and outer walls is evacuated to remove air, reducing conduction and convection.

Polished Stainless Steel Interior: Reflects radiant heat, further enhancing thermal retention.

Optional Lid Integration: Helps maintain temperature and prevents accidental spills during transport.

Performance Metrics:

Cold beverages: maintain temperature for 4–6 hours

Hot beverages: maintain warmth for 1.5–3 hours

This technology ensures consistent performance whether used indoors or outdoors, making it suitable for offices, homes, picnics, and camping.

Ergonomic and Functional Design

The 15oz tumbler is designed for user comfort and portability:

Slim Profile: Fits standard cup holders and backpack compartments.

Polished Exterior: Provides a comfortable grip and resists scratches.

Stable Base: Minimizes tipping on uneven surfaces.

The design balances thermal performance with practical usability, enhancing consumer satisfaction.

Product Structure, Materials, and Manufacturing

Structural Composition

The beer cup consists of several critical components:

Inner Liner: Food-grade stainless steel (SUS 304/316) ensures corrosion resistance and preserves taste.

Outer Shell: Polished stainless steel for durability and premium aesthetics.

Vacuum Layer: Creates the double-wall thermal insulation.

Base: Flat, weighted design for stability.

Optional Lid: BPA-free silicone lid provides spill resistance and enhances thermal retention.

Material Selection

SUS 304/316 Stainless Steel: Offers long-term durability, corrosion resistance, and taste neutrality.
