Definitions

• the invention relates to a device for packaging and dispensing pasty products.
• a device for packaging and dispensing pasty products known comprises a rigid bottle 1 carrying a pump body 2 mounted on a ring 3 fixed in the neck of the rigid bottle 1 and secured to the neck of a pocket with flexible and deformable wall 4 containing the product to be dispensed.
• the pump body 2 comprises a lower part inserted and clipped into the orifice of the ring 3 and carrying a seal 5 housed in an annular groove 6 arranged in this lower part and formed by a lower rib 7 and an upper rib. 7 'carried by this lower part.
• the ring 3 is also attached by welding to the pocket and clipped into the bottle 1.
• This annular groove 6 for housing the seal ensures its maintenance and avoids its loss before assembly of the pump in the bag during final packaging, the seal ensuring the long-term sealing of the device. It guarantees the so-called “airless" airtightness of the device.
• the lower end of this pump body comprises a clipping collar 12 which is force-fitted on a lower annular abutment rib 8 carried by the orifice of the ring 3 and the seal 5 held in its groove 6 is then slipped over this abutment rib 8 of the ring, along the peripheral surface of the ring 3 to the stop of the lower rib 7 forming the groove 6 of the seal against the abutment rib 8 of the ring.
• the invention proposes a device for packaging and dispensing pasty products comprising a rigid bottle carrying a pump body mounted on a ring fixed in the neck of the rigid bottle, comprising a peripheral annular peripheral rib abutment cooperating with a clipping collar carried by the pump body, for fixing the pump body on said ring , this ring being secured to the neck of a pouch flexible and deformable wall containing the product to be dispensed, the pump body carrying, above said clipping collar, a seal housed in an annular groove carried by the pump body, characterized in that at least the abutment rib or the clipping collar is provided with at least one vent.
• said vent is arranged in said clipping collar carried by the lower part of the pump body.
• said vent consists of a slot arranged in said rib or said collar.
• said rib or said flange comprises at least two vents distributed on its periphery.
• said seal is compressed against a cylindrical wall of said ring adjacent to said clipping collar, in the mounted position.
• said annular groove is formed by at least one lower rib abutting against said lower peripheral annular abutment rib in the mounted position.
• the device is waterproof type said "airless".
• the invention is described below in more detail with the aid of a figure representing a preferred embodiment of the invention.
• Figures 1 and 2 are vertical sectional views of a device for packaging and dispensing pasty products according to the prior art.
• Figure 3 is a vertical sectional view of a pasty product packaging and dispensing device according to the invention, with an associated detail view and in mounting position.
• Figure 4 is a vertical sectional view of a device for packaging and dispensing pasty products according to the invention, with an associated detail view and mounted position.
• Figure 5 is a perspective view of a pump body of a device for packaging and dispensing pasty products according to the invention.
• a device for packaging and dispensing pasty products comprises a rigid bottle 1 carrying a pump body 2 mounted on a ring 3 fixed in the neck of the rigid bottle 1, comprising a lower peripheral annular rib of abutment 8 cooperating with a clipping collar 12 carried by the pump body and secured to the neck of a pouch flexible and deformable wall 4 containing the product to be dispensed.
• the pump body 2 comprises a lower part inserted and clipped into the orifice of the ring 3 and carrying an O-ring seal 5 housed in an annular groove 6 arranged in this lower part and formed by a lower rib 7 and a rib. upper 7 'carried by this lower part.
• At least the abutment rib or the clipping collar 8, 12 is provided with at least one vent 11.
• the vents 11 are two in number, distributed on the periphery of the rib, and are arranged in the clipping collar 12 carried by the lower part of the pump body. As best seen in FIG. 5, each vent 11 consists of a slot of calibrated dimension arranged in the clipping collar 12.
• the lower rib 7 of the groove 6 of the seal abuts against the abutment rib 8 worn through the orifice of the ring 3, by means of two surfaces of the same inclination providing abutment blocking of flat surfaces against each other.
