Indeed, after the plastic compression spring has been subjected to compression (after a user has pressed the push-button 11), the plastic compression spring may see its elasticity decrease. Because of this loss of elasticity, the compression spring may not have enough force to return the push button 11 to a position in which the valve is in the closed position with sufficient sealing. This loss of elasticity can be significant from the first compression stress of the compression spring.
  • the seal 32 In order to reduce the creep effect of the compression spring, it is advantageous for the seal 32 to be shaped beforehand against the counter-seal 30.

  • the predetermined duration is less than 2 s.
  • the predetermined duration is less than 1 s.
  • a tightness verification step can then be implemented in order to ensure that the valve 12 retains sufficient tightness when it is in its closed position.
  • This method of prior shaping makes it possible to avoid shaping of the seal 32 with the counter-seal 30 by the spring itself, which could significantly reduce the elasticity of the spring from its first stress in compression.
  • a seal 32 previously shaped against the seal 30 therefore makes it possible to reduce the creep of the plastic compression spring.

  • the hollow body 4 may comprise two fins 28a and 28b at its end E1. These two fins 28a and 28b allow a user to more easily exert pressure F on the push button 11. For example, when the user presses his index finger against the fin 28a, his middle finger against the fin 28b and his thumb against the push button 11, the user can more easily exert sufficient pressure on the push button 11 by forming a clamp between on the one hand, the thumb, and on the other hand, the middle finger and the index finger.

This arrangement between the opening 82 and the opening 92 allows the air circulating in the air inlet channel 8 to enter the container 3 to take the place of the liquid which leaves the container 3 through the liquid outlet channel 9, without being prevented by the liquid arriving in the supply chamber 7.
  • the liquid outlet channel 9 can be extended by a pouring spout 16 protruding from the surface of revolution 5.
  • the pouring spout 16 extends between the opening 91 in the surface of revolution 5 and an outlet mouth of liquid 35 ( figure 1 , figure 6 , figure 7 , figure 18, figure 19 ).
  • the opening 81 in the surface of revolution 5 through which the air enters the air inlet channel 8 is therefore recessed with respect to the liquid outlet mouth 35 of the spout 16 through which the liquid leaves the container 3 passing through the liquid outlet channel 9.
  • This spout 16 prevents the liquid leaving the container 3 through the opening 91 of the pouring cap 1 and the liquid outlet mouth 35 from preventing the air to enter the air inlet channel 8 through the opening 81.
  • the liquid outlet mouth 35 of the spout 16 may have at least one indentation 34. This or these indentations 34 make it possible to avoid the formation of a liquid meniscus at the level of the liquid outlet mouth 35 of the spout 16. The formation of a meniscus could disturb the flow of the liquid when the valve 12 passes from the closed position to the open position.
  • the liquid outlet mouth 35 has two notches 34 at opposite edges of the liquid outlet mouth 35.
  • the two notches 34 can be distributed on either side of an axis parallel to the central axis A1.
  • the actuation chamber 6 can also comprise a guide cylinder 17 having an axis of revolution parallel to the central axis A1.
  • the guide cylinder 17 protrudes into the actuation chamber 6 on the surface 18 of the actuation chamber 6 opposite the first end E1 of the hollow body 4.
  • the guide cylinder 17 has a longitudinal axis parallel to the axis central A1.
  • the guide cylinder 17 comprises a free end 19.
  • the stem of the valve 14 is able to slide in the guide cylinder 17 when the push button 11 is actuated by a user.
  • the actuation chamber 6 is configured so that the push button 11 presses against the free end 19 of the guide cylinder 17 to close said free end 19 when the valve 12 is in the open position ( figure 7 ). This contributes to preventing the liquid circulating in the liquid inlet channel 9 from penetrating into the actuation chamber 6, the liquid being blocked in the guide cylinder 17 by the closure of the free end 19 by the push button 11.
  • the elastic element 15 is a spring
  • said spring is arranged in the actuation chamber 6 between the push button 11 and the surface 18 of the actuation chamber 6 on which the first guide cylinder 17 protrudes.
  • stem 14 of valve 12 includes a circular bead 33 on the surface of stem 14 ( figure 18 ).
  • the circular bead is perpendicular to the central axis A1.
  • the circular bead 33 rotates around the central axis A1.
  • the circular bead 33 is configured to bear against the surface 18 of the unopened end of the cylinder of the actuating chamber 6 (the surface opposite the end E1 of the hollow body 4) when the valve 12 is in the open position ( figure 19 ). This contributes to preventing the liquid circulating in the liquid inlet channel 9 from penetrating into the actuation chamber 6, the liquid being blocked by the circular bead 33.
  • the elastic element 15 is a spring
  • said spring is arranged in the actuation chamber 6 between the push button 11 and the surface 18 of the actuation chamber 6.
  • the pourer cap 1 may also include a guide cylinder 20 projecting into the liquid outlet channel 9.
  • the stem 14 of the valve 12 is adapted to slide in the guide cylinder 20.
  • the guide cylinder 20 may project the wall 29a, 29b separating the liquid outlet channel 9 and the air inlet channel 8.
  • the guide cylinder 20 comprises a longitudinal slot 21.
  • the stem 14 of the valve 12 further comprises a longitudinal rib 22.
  • the longitudinal rib 22 of the stem 14 of the valve 12 is configured to slide in the longitudinal slot 21 of the guide cylinder 20 when the stem 14 of the valve 12 slides in the guide cylinder 20. This prevents the valve 12 from rotating around its longitudinal axis. This also makes it possible to indicate the position of the valve 12 around its longitudinal axis during the manufacture of the pouring cap 1.
  • the air inlet channel 8 comprises a portion 8a and a portion 8b.
  • Portion 8a passes through hollow body 4 from opening 81 in surface of revolution 5 to portion 8b.
  • Portion 8b extends between portion 8a and opening 82 opening into supply chamber 7.
  • wall 29a, 29b separating air inlet channel 8 and outlet channel of liquid 9 can also have a portion 29a and a portion 29b.
  • the portion 29a of the wall 29a, 29b separates the portion 8a of the air inlet channel 8 from the liquid outlet channel 9.
  • the portion 29b of the wall 29a, 29b separates the portion 8b of the inlet channel from air 8 from the liquid outlet channel 9.
  • the portion 29a is substantially parallel to the portion 8a.
  • Portion 29b is substantially parallel to portion 8b.
  • portion 8a has a longitudinal axis which forms an acute angle with a plane perpendicular to central axis A1.
  • Part 8b has a longitudinal axis substantially parallel to central axis A1.
  • the portion 8b protrudes from the surface of revolution 5. This makes it possible to distance the opening 82 emerging into the supply chamber 7 from the opening 92 emerging into the supply chamber 7. This arrangement allows the air circulating in the air inlet channel 8 to enter the container 3 to take the place of the liquid which leaves the container 3 through the liquid outlet channel 9, without being prevented by the liquid arriving in the chamber of food 7.
  • the fastening element 10 may comprise a collar 23 having a bearing surface 24 that is circular.
  • the support surface 24 is configured to receive a pressure force exerted parallel to the central axis A1 by a tool for fitting the pouring cap 1 making it possible to snap the fixing element 10 onto the neck 2 of the container 3 .
  • the fixing element 10 may further comprise a marker rib 25 in the extension of the opening 81 and of the opening 91 in the surface of revolution 5.
  • the marker rib 25 is configured to indicate to the tool for fitting the pouring cap 1 the positions of said opening 81 and of said opening 91 in order to correctly place the pouring cap 1 on the container 3.
  • the pouring cap 1 may also comprise an internal skirt 26 in the extension of the supply chamber 7 ( figure 6 and figure 7 ).
  • the inner skirt 26 contributes to the sealing between the neck 2 of the container 3 and the pouring cap 1.
  • the pouring cap 1 can further comprise a cap 27 configured to be removably fixed to the hollow body 4 to cover at least a part of the hollow body 4 so that the push button 11 is not accessible to a user and the channel of liquid outlet 9 and the air inlet channel 8 are protected from the external environment.
  • the cap 27 is made of plastic material by injection molding technology.
  • the plastic material can be high density polyethylene (HDPE) or polypropylene (PP).
