40 Oz Stainless Steel Tumbler

 

A 40 oz double-wall vacuum insulated stainless steel tumbler engineered for all-day temperature retention, featuring an ergonomic side handle, vehicle cup-holder compatible tapered base, splash-proof press-in lid, and reusable straw for high-volume beverage consumption across retail and custom brand programs.

 

 

The 40 oz Stainless Steel Tumbler combines high-capacity liquid storage with double-wall vacuum insulation to maintain beverage temperature for extended periods. Constructed with food-grade 304 stainless steel interior liners, this tumbler features a precision-tapered base that fits standard automotive cup holders, a heavy-duty ergonomic handle, and a multi-function lid system designed for commercial customization and retail distribution.

 

 

Double-Wall Vacuum Thermal Insulation: Maintains cold drinks at temperature for up to 24 hours and hot liquids warm for up to 7 hours through an evacuated air gap between interior and exterior wall structures.

Food-Grade 18/8 Stainless Steel Construction: Manufactured with SUS304 interior walls to prevent metallic flavor transfer, chemical leaching, and internal corrosion over repeated wash cycles.

Car Cup Holder Compatible Base: Tapered lower silhouette measures 75mm in outer diameter, fitting standard vehicle cup holders despite the full 40 oz liquid volume capacity.

Ergonomic Reinforced Handle: Dual-riveted or ultrasonic spot-welded side handle provides secure grip stability without loosening under maximum fluid weight.

Dual-Function Splash-Resistant Lid: Rotating top closure accommodates direct sipping, straw insertion, and full coverage sealing to prevent splashing during transit.

Sweat-Free Exterior Surface: Vacuum insulation layer eliminates surface condensation, keeping outer walls dry and preventing slip hazards or moisture rings.

The interior chamber is deep-drawn from food-grade 18/8 (SUS304) stainless steel sheets, ensuring complete corrosion resistance and zero taste retention. An automated vacuum extraction process removes air between the inner and outer steel shells to a pressure level below 0.001 Pa. A copper coat is applied to the exterior surface of the inner wall to reflect radiant heat energy, boosting thermal efficiency by up to 15%.

Outer casings are cold-formed from durable stainless steel to resist structural denting upon impact. All plastic lid components are molded from food-grade, BPA-free AS or Tritan co-polyester, fitted with precision silicone gaskets to form a splash-tight pressure fit against the bottle neck.

 

 

Lid Mechanisms: Available with 3-position rotating lid (straw opening, direct sip opening, full closure cover) or flip-straw leak-proof lids for active outdoor use.

Handle Design Configurations: Solid color-matched injection-molded polypropylene handles, soft-touch rubberized ergonomic grips, or detachable metal-bracket handle assemblies.

Straw Accessories: Reusable food-grade plastic straws, stainless steel straws with silicone soft-tips, or collapsible telescopic straws with cleaning brushes.

 

 

Powder Coating: Textured, slip-resistant surface coating providing enhanced scratch durability and chip resistance for outdoor and daily use.

Matte & Gloss Spray Painting: Smooth liquid-spray finishes ideal for high-definition silk screen or full-wrap heat transfer graphics.

Gradient & Electroplated Finishes: Multi-tone color blends, metallic mirror plating, and iridescent finishes for premium retail collections.
