800ml Octagonal Vacuum Flask with Interchangeable Lids

Product Highlights

Developing a separate bottle body for every drinking lid increases tooling, sampling, inventory and packaging complexity. Interchangeable lid options allow brands to keep one recognizable octagonal flask body while adjusting the drinking experience for sports, commuting, school, travel or outdoor retail programs.

• 800ml capacity reduces refill stops during longer daily routines
• Eight-sided body creates defined gripping surfaces and distinctive shelf presentation
• Interchangeable lids support different drinking and carrying preferences
• Straw-lid configuration supports regular sipping during work or exercise
• Vacuum-insulated construction is intended for hot or cold beverages
• Clean outer walls support custom colors, logos and printed patterns

Specifications

Customization and MOQ

The octagonal outer wall gives artwork a different visual rhythm from a standard round flask. Buyers can discuss solid colors, gradients, restrained logos, full-body patterns, laser marking, screen printing and other decoration methods after the final surface finish and artwork area have been confirmed.

Customization can also cover lid selection, lid color, handle color, accessory combinations, individual color boxes, instruction sheets and export carton marks. MOQ depends on the selected lid, color, decoration and packaging configuration and should be confirmed before quotation.

Samples are charged during development, with the sample fee refundable after the qualifying bulk order is placed. The approved sample should record the body color, logo position, selected lid, sealing parts, packaging structure and carton information for bulk-production reference.

Certifications and Buyer Checks

Food-contact reports, material declarations, labeling requirements and test standards depend on the destination market and final material configuration. Buyers should provide the target country and required document list before sampling so the applicable body, lid, coating, printing and packaging scope can be checked.

Sample inspection should cover lid compatibility, sealing-ring placement, thread engagement, drinking-opening closure, handle movement, coating appearance, logo durability and packaging fit. Insulation performance should be reviewed using an agreed starting temperature, filling level, test duration and ambient condition rather than an unsupported number of hours.

Each selected lid should receive a separate leak test because straw, direct-drink and carry-lid structures may use different closures and sealing components. Bulk-production checks should follow the approved lid and accessory combination.

Applications

During extended office hours or school days, the 800ml capacity reduces repeated trips for refilling. A straw-lid configuration supports regular sipping at a desk or between exercises, while a covered direct-drink lid may be preferred during travel, hiking or outdoor breaks. Carry-lid options provide a defined point for retrieving the flask from a backpack or locker.

The recognizable octagonal profile also suits outdoor brands, sports collections, corporate gifts, campus merchandise and private-label retail programs. Buyers developing additional capacities or conventional round bodies can compare options in the stainless steel vacuum flask collection.

Why Choose BlueGreen Drinkware

A multi-lid product program requires more than attaching different caps to the same bottle. Each configuration must be checked for thread compatibility, sealing-ring position, drinking clearance, handle movement, accessory fit and packaging space before it is approved as a separate retail version.

BlueGreen Drinkware supports project confirmation across the details that affect bulk consistency: selected lid set, body color, lid color, logo position, artwork orientation, surface finish, accessory list, individual packaging and carton marks. Keeping these items tied to an approved sample helps buyers manage several product versions around one core flask body.
