A double-seal intermediate element lets carbonated cans reclose after opening, limiting CO2 loss, spills, and tampering while easing production.

A pivoting chamber wall changes vacuum volume to fit larger foods, speed evacuation for smaller items, and save drawer space.

A membrane-driven vacuum switch enables sealing bar power only after vacuum builds, preventing open-lid activation and user burns.

A deformable inner cover bends under vacuum to disengage the driving gear, preventing transmission overload while preserving food freshness.

Integrated valves on sealing tools switch between rough and fine vacuum to cut chamber evacuation time and improve packaging machine throughput.

Independently controlled parallel 2/2-way valves shorten gas exchange while limiting powder disturbance in modified atmosphere packaging.

A dual-chamber package uses a baffled liquid chamber and sealed gas space to keep BAOs sterile, submerged, and protected during transport.

Preheating an intraocular lens in its container improves flexibility, enabling smaller eye incisions and faster unfolding during implantation.

Negative pressure inflates elastic airbags to lift packaged chips, reducing vibration, friction, and substrate cracking during transport.

A welded stainless-steel bucket body replaces aging polymers to prevent cracking, harmful decomposition, and pet food spoilage under vacuum.

A memory-structured elbow bends the container rim inward to remove sharp sealed edges without weakening the thermoformed periphery.

A gas-tight sleeve and staged vacuum degas open containers during filling, then inert gas forms a protective bridge to limit product loss.

A two-part vacuum valve seals through flexible foil to vacuumize different food containers without dedicated adapters, saving space and material.

A pump-fed storage and chamber layout keeps aerosol material flowing to the wick while showing remaining volume to avoid premature cartridge replacement.

Vacuum-sealed or inert-gas-packed filling is poured into a bread cavity to keep larger ingredients fresh, contained, and easy to handle.

A permeable liquid reservoir hydrates nicotine pouches evenly, while a color-changing tag shows when moisture is at the right level.

A recess-guided tray loading approach stabilizes packaging trays during insertion, preventing tipping, jamming, and sealing-tool downtime.

A movable support disc lifts trays to a higher sealing position, cutting lower-tool volume, evacuation time, and tray sealer cost.

Negative-pressure filling is paired with degassing, weighing, inert gas purging, and top-up to keep open-container powder fills accurate.

Vacuum filling with inert gas and in-cycle weight checks stabilizes powder density and delivers precise open-container fill levels.

A sensor-controlled vacuum container preserves perishables by maintaining sub-atmospheric pressure while supporting odor filtering and child-resistant opening.

External weighing of the supply container enables precise, contamination-free dose filling in a single-use isolator without internal scales.

A sterilizable vacuum chamber restrains closure nests during sealing to keep pharma containers aseptic, leak-tight, and free of trapped air.

A silicone flexible valve deforms under vacuum and reseals the air hole, helping Mason jars avoid leakage and maintain a longer sealing cycle.
