FIELD: caps with tight seal for carboys, especially for glass ones, with an allowance of more or less than a multimetre. SUBSTANCE: cap 6 is compressed under the action of heat and forms a single link, which is removed by separation of the seal. This link can be used for automatic capping machines, and cap 6 is closed at smaller end 7 on the slot of round cover 1 of the top, when it sags under flange 5 of the top forming concave peripheral rim 11, and thus forming a single link that fits for carboys of different dimension due to the provision of ribs 3 of tubular link 2 of the top. EFFECT: enhanced reliability. |
