TO 77mm Twist Lid honeycomb - Case of 950 units

01 · COMPATIBILITY

The TO figure names the mouth, not the jar's outside diameter

TO 77 is the name of the Twist-Off mouth, on a GPI 2040 profile, with six closing lugs. Measuring the outside of the jar tells you nothing: a jar of similar diameter but with a different number of lugs or a different mouth height will not close properly, and you only find out when it loses vacuum. From our catalogue, it fits the TO 77 jars: 1 kg honeycomb, plain V720, 12REF 347 ml, 0.5 kg plain V370, 16REF 445 ml, V580 and 1/4 Gallon 900 ml.

02 · PASTEURISATION

The limit belongs to the lid, not to the whole process

The datasheet declares pasteurisation up to 100 °C for 60 minutes. That figure says what the lid withstands, not that any heat treatment is validated: temperature, time, vacuum, sealing compound, product and jar are validated as one system. And within a single run it is unwise to mix lids from different batches or profiles.

03 · STORAGE

What degrades is the sealing compound

The gasket that seals against the glass is the delicate part, and it goes before the metal does. Keep the lids in their packaging, clean and dry, between 5 and 35 °C and below 70 % relative humidity; the documentation sets two years as the maximum unless specifically approved. Avoid knocks on the skirt and stacks that deform the lugs: a bent lug will not seal even if the lid looks intact.

FROM THE APIARY

A Twist-Off does not screw on like a bottle cap: the six lugs ride up a short ramp and the whole closure is a quarter turn. Sit it flat until you feel it settle, turn to the stop and leave it there: carrying on does not seal better, it bends the lug and leaves the jar impossible to open. If it grates or feels like the thread has stripped, lift it off and set it down again — there is no thread to strip, a lug has ridden over its ramp.

04 · BEFORE YOU BUY
