Core Concepts and Key Technologies

Double-Wall Vacuum Insulation

The central technology behind this beer cup is double-wall vacuum insulation, which creates a highly effective barrier between the beverage and the external environment:

Vacuum Layer: Eliminates air between inner and outer walls, minimizing heat transfer through conduction and convection.

Polished Stainless Steel Interior: Reflects radiant heat, preserving both hot and cold temperatures efficiently.

Optional Lid Integration: Enhances thermal performance and reduces spills during movement or outdoor activities.

Performance Metrics:

Cold beverages: retain temperature for approximately 3–5 hours

Hot beverages: retain warmth for approximately 1–2.5 hours

This technology ensures beverages remain enjoyable in environments where temperature stability and portability are critical, such as picnics or outdoor excursions.

Compact and Ergonomic Design

Designed for portability, the 10oz beer cup features:

A slim, cylindrical profile for efficient packing in picnic baskets or backpacks.

Polished exterior for comfortable grip and easy cleaning.

Stable base to prevent tipping on uneven outdoor surfaces.

The ergonomic design accommodates frequent outdoor use, whether for morning coffee, chilled beer, or soft drinks.

Product Structure, Materials, and Manufacturing

Structural Composition

The beer cup is composed of:

Inner Liner: Food-grade stainless steel (SUS 304 or 316) for corrosion resistance and neutral taste.

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

Vacuum Layer: Provides the thermal insulating effect.

Base: Flat and stable for outdoor surfaces.

Optional Lid: BPA-free silicone for spill prevention and enhanced thermal retention.

Material Selection

SUS 304/316 Stainless Steel: High corrosion resistance, longevity, and taste neutrality.

Polished Exterior: Provides hygiene, aesthetic appeal, and scratch resistance.
