Definitions

• the present invention relates to a child proof closure applicable to a container.
• Child proof closures are closures that are equipped with special features to minimise the risk of a child under the age of 3 being able to open them. For example, for opening the closure the user must apply axial compression and simultaneous unscrewing on the closure. In fact, it has been demonstrated that the combined action is unnatural and unlikely to be implementable by a child aged under 3.
• a child proof closure in which there is a capsule applicable to the neck of the container for occluding the opening hole.
• Such capsule is enveloped by a capsule cover applicable by a user to prevent the latter being able to access the capsule below.
• the capsule cover further comprises an elastic means that allows the capsule cover to be moved axially away from the capsule by disengaging the teeth from the relevant seats.
• Such elastic means comprises tabs that protrude from a top (which extends orthogonally to the axial direction) of the capsule cover. By bending, such tabs allow the capsule cover to be screwed onto the capsule.
• the capsule and capsule cover further comprise lateral straps that can interact with each other.
• these straps interact with each other, transmitting the torque to the capsule, which is screwed onto the container.
• the capsule cover is unscrewed the straps slide onto each other (due to their specific geometry) and no torque is transmitted to the capsule (unless an axial thrust is also applied, which would cause the engagement not of the straps, but of the aforementioned teeth).
• reference number 1 denotes a child proof closure for closing a container.
• Such container is, for example, intended to contain pharmaceutical products.
• closure 1 comprises a closure capsule 2 for closing the container.
• the capsule 2 can be screwed/unscrewed with respect to the container.
• the capsule 2 defines a cap that allows an opening of the container to be occluded.
• the closure 1 further comprises a capsule cover 3.
• the capsule cover 3 is superimposed with and envelops the capsule 2. It prevents a user from accessing the capsule 2.
• the capsule 2 and the capsule cover 3 in a first configuration are moved towards each other along an axial direction. In a second configuration (see figure 1 ) they are moved away from each other along the axial direction.
• the axial direction is identified by an axis 4 along which the capsule 2 is unscrewed/screwed with respect to the container. Such axial direction is therefore defined by an axis of the helix of the threading with which the capsule 2 is screwed to the container.
• the axial direction is orthogonal to the outlet mouth of the container.
• the closure 1 comprises a disengageable means 5 for transmitting an unscrewing torque from the capsule cover to the capsule.
• the unscrewing torque allows the unscrewing of the capsule 2 from the container.
• the dispensing opening of the container can therefore be opened.
• the disengageable means 5 is afforded partially on the capsule 2 and partially on the capsule cover 3.
• the means 5 is therefore partially solidly constrained to the capsule 2 and partially solidly constrained to the capsule cover 3.
• the disengageable means 5 is partially in a monolithic single body with the capsule 2 and partially in a monolithic single body with the capsule cover 3.
• the disengageable means 5 for unscrewing the capsule 2 is reciprocally engaged in the first configuration and reciprocally disengaged in the second configuration. Therefore, in the first configuration, by acting on the capsule cover 3, it is possible to unscrew the capsule 2 and remove it from the dispensing opening of the container. In the second configuration the rotation of the capsule cover in any one of the two directions does not allow the unscrewing of the capsule 2 from the container.
• the disengageable means 5 comprises at least one tooth 9 (preferably afforded on the capsule cover 3) which is engaged in a corresponding slot 90 (preferably afforded on the capsule 2).
• the closure 1 comprises an elastic means 6 that exerts an axial force for moving the capsule cover 3 away from the capsule 2 to allow the passage from the first to the second configuration and that may be integrated into the capsule 2 and/or the capsule cover 3.
• the capsule cover 3 comprises a disc 31 and a lateral wall 32 that extends from the disc 31 .
• the lateral wall 32 of the capsule cover 3 is substantially shaped like a cylindrical lateral wall.
• the capsule 2 comprises an upper cap 21 and a lateral wall 22.
• the lateral wall 32 of the capsule cover 3 faces and surrounds the lateral wall 22 of the capsule 2.
• the cap 21 of the capsule 2 faces the disc 31 of the capsule cover 3.
• the elastic means 6 comprises a Belleville spring 60. Appropriately, it is made of plastic.
• the Belleville spring 60 defines an annular cavity 61 .
• the cavity 61 is more pronounced with respect to the second configuration.
• the Belleville spring 60 is therefore more deformed with respect to the second configuration.
• the Belleville spring 60 is integrated into the capsule 2.
• the cavity 61 is turned towards the capsule cover 3.
• the Belleville spring 60 defines a monolithic single body with the remaining parts of the capsule 2.
• the Belleville spring 60 comprises a cylindrical symmetry about the unscrewing/screwing axis 4 of the capsule 2.
• the Belleville spring 60 appropriately comprises:
• the base 63 comprises an annular step 65 which is raised towards the capsule cover 3 moving from a radially more external position to a radially more internal position.
• the Belleville spring 60 (in particular the slope 64) is made of polyethylene.
• the slope 64 starting from the step 65 and moving radially towards the top 62 first defines a descent and then an ascent.
• the capsule 2 and the capsule cover 3 comprise straps 91 , 92 which in the second configuration are reciprocally engaged to allow the transmission from the capsule cover 3 to the capsule 2 of a torque that allows the screwing of the capsule onto the container.
• the straps 91 , 92 instead slide on each other whenever the capsule cover 3 turns in the opposite direction (not transmitting to the capsule 2 an unscrewing torque thereof from the container).
• Such straps 91 , 92 are afforded on an internal lateral surface of the capsule cover 3 and on an external lateral surface of the capsule 2.
• the present invention provides important advantages.
