Definitions

  • the present invention relates to a container of a product, for example a cosmetic (creams, serums, etc.) or eye drops or other and relative dispensing method.
  • a cosmetic creams, serums, etc.
  • eye drops or other and relative dispensing method.
  • Containers are known for containing creams, which are provided with a tank for containing the product and a dispenser with a cap.
  • the cap is removable from the tank and allows access to the underlying dispenser. By compressing the tank, the product exits from the dispenser. The cap can then be reapplied by connecting it with a thread or with pressure by elastic deformation.
  • a drawback of such a solution is related to the fact that once the cap is removed to dispense the product, there is the risk of losing it. Furthermore, for opening and closing the container it is necessary to have both hands available and advantageously also a support surface.
  • the object of the present invention is to propose a container of a product and relative dispensing method which allow to facilitate and make opening the container more convenient, minimising the risk of the drawbacks described above.
  • FIG. 1 shows a sectional view of a container according to the present invention
  • figure 2 shows an exploded view of the container of figure 1 ;
  • FIG. 5 shows a perspective view of some components of figure 1 ;
  • FIG. 8 shows a bottom view and a perspective view of a component of figure 1 ;
  • a container of a product is denoted by the reference numeral 1 in the appended drawings.
  • a product is typically liquid or semi-solid (highly viscous).
  • a particular application of the container 1 is a dropper.
  • the container 1 comprises a tank 2 for containing the product.
  • Such a tank 2 can be compressed manually by a user.
  • the tank 2 has lateral walls which can be compressed towards each other for dispensing the product.
  • the container 1 comprises a system 3 for dispensing the product which is placed in the tank 2.
  • the dispensing system 3 comprises a product dispenser 31.
  • the dispenser 31 may be a single monolithic body or an assembly of several parts.
  • the dispensing system 3 also comprises a system 32 for transmitting motion from the cap 33 to the dispenser 31.
  • the transmission system 32 allows the dispenser 31 to be moved towards or away from the tank 2 so as to position the dispenser 31 in a more projected position for dispensing and in a more retracted position when not in use.
  • the dispensing system 3 suitably comprises a cap 33 of the dispenser 31 .
  • the cap 33 is inseparably constrained to the tank 2.
  • the transmission system 32 is intended to move said dispenser 31 between: i) an operating configuration in which said dispenser 31 enables the dispensing of the product through the cap 33; ii) a rest configuration in which said dispenser 31 is retracted towards the tank 2 with respect to the operating configuration.
  • the dispenser 31 is protected externally by the cap 33. In the rest configuration, the dispenser 31 is not accessible from the outside.
  • the distance between the cap 33 and the tank 2 is substantially unchanged.
  • the cap 33 is integrated in the container 1 (for example it is inseparable from the tank 2).
  • the cap 33 uncovers the dispenser 31 , making it accessible from the outside, in the rest configuration it protects the nozzle 313.
  • the dispenser 31 is inaccessible from outside the container 1. Therefore, it is protected from contamination and dust. It also prevents dispensing the product from the container 1 , avoiding accidental soiling.
  • the cap 33 is movable. In particular, it is movable with respect to the tank 2.
  • the cap 33 assumes a first position with which the rest configuration is associated and a second position with which the operating configuration is associated. In the second position the cap 33 is rotated with respect to in the first position. In particular in the second position the cap 33 is rotated 180° with respect to the first position.
  • the cap rotates around a rotation axis. Such an axis conveniently coincides with a preponderant longitudinal extension axis of the tank 2 (which is usually perpendicular to a support base of the container 1 ).
  • the dispenser 31 In the operating configuration the dispenser 31 preferably projects outside the cap 33 (although possibly, in a particular solution, it may not project). In the rest configuration the dispenser 31 does not project outside the cap 33.
  • the rest configuration and the operating configuration are assumed at two opposite stroke ends of a movement stroke of the cap 33.
  • the cap 33 suitably defines a cavity facing the tank 2. In such a cavity, the cap 33 at least partially houses the dispenser 31.
  • the cap 33 comprises a base 331 and a lateral side 332 which extends from the base 331 towards the tank 2.
  • the cap 33 advantageously comprises a slot 330; such a slot 330 is afforded on the base of the cap 33.
  • the slot 330 is a through slot and crosses the thickness of said base 331.
  • the slot 330 allows the dispensing of the product in the operating configuration. In the operating configuration the dispenser 31 crosses the slot 330. Thereby, the dispenser 31 protrudes externally and can dispense the product.
  • the dispenser 31 preferably comprises:
  • a cuff 311 placed at an outlet of the tank 2; such a cuff 311 defines a concavity.
  • the product in output from the tank 2 advantageously enters the cuff 311 (in particular in the concavity defined by the cuff 311 );
  • the dispenser 31 (advantageously both cuff 311 and spout 312) is rigid.
  • the container 1 Suitably at the output from the tank 2 the container 1 comprises a pin 5 provided with a passage hole 50 which crosses it from side to side.
  • a hole 50 is intended to be crossed by the product.
  • the hole 50 comprises a minimum passage section comprised between 5 and 15 millimetres so as to facilitate the return of the product towards the tank 2 when there is a passage from the operating configuration to the rest configuration.
  • the pin 5 comprises an annular slot 53 in which a mouth of the tank 2 engages.
  • the dispenser 31 (in particular the cuff 311 ) is rotatable around the pin 5.
  • a fluid-dynamic seal 51 (advantageously ringshaped) is interposed between the dispenser 31 and the pin 5.
  • the seal 51 is advantageously integral with the cuff 311 and comprises a sealing lip which rests on a side surface of the pin 5.
  • the pin 5 is suitably a distinct body from the tank 2 and assembled thereto.
  • a chamber 52 between the pin 5 and the cuff 311 for the product waiting to be dispensed.
  • Such a chamber 52 is variable in volume. In particular in the operating configuration such a chamber 52 has maximum volume, while in the rest configuration it has minimum volume (at most even zero). With the passage from the operating configuration to the rest configuration, the product present in such a chamber 52 spontaneously returns to the tank 2 (in the preferred solution crossing the hole 50 present on the pin 5).
  • the dispenser 31 comprises a nozzle 313 placed inside said spout 312.
  • the product being dispensed transits between the nozzle 313 and the spout 312.
  • the nozzle 313 is more rigid with respect to the spout 312.
  • the nozzle 313 is suitably movable axially along the spout 312. Such an expedient allows the entry of air during the relaxation step of the container 1 after the dosage of product.
  • the nozzle 313 comprises a body having two opposite ends connected by a lateral wall. Such a body is full, and does not have an internal duct (possibly there may be a shaping on the outer surface).
  • the nozzle 313 suitably comprises a chamfer to facilitate centring with the spout 312 at an end which is more distanced from the tank 2.
  • the nozzle 313 comprises a lateral swelling. Such an expedient prevents the nozzle 313 from falling towards the tank 2. Such a lateral swelling suitably comprises a cut. This facilitates the passage of product and air.
  • the lateral wall of the nozzle 313 laterally comprises a propeller, advantageously two-pronged. This increases the sliding surface of the product; thus the influence of the pressure created by the reduction of the volume interposed between the cuff 31 1 and the outlet of the tank 2 decreases during the closing/retracting step of the dispensing system.
  • the spout 312 comprises a passage section narrowing. Such a section narrowing retains the nozzle 313, preventing it from falling inside the cuff 31 1 .
  • the container 1 comprises an element 4 interposed between the dispenser 31 and the cap 44.
  • the interposed element 4 envelops the cuff 311 .
  • the cap 33 is movable with respect to the interposed element 4.
  • the interposed element 4 preferably comprises an opening 40; in the operating configuration the opening 40 and the slot 330 are at least partially superposed, allowing the passage of the dispenser 31.
  • the dispenser 31 crosses the opening 40.
  • the dispenser 31 lies completely outside said opening 40.
  • the interposed element 4 at least partly superposes the slot 330, occluding it.
  • the opening 40 extends in an arc, for example in a half-moon shape (in particular an arc of a circle). This allows to avoid interference between the dispenser 31 and the interposed element 4 during the transition from the rest configuration to the operating configuration.
  • the opening 40 does not intercept the rotation axis of the cap 33 (in the operating configuration and/or in the rest configuration and/or during the passage between the operating configuration and the rest configuration).
  • the slot 330 does not intercept the rotation axis of the cap 33 (in the operating configuration and/or in the rest configuration and/or during the passage between the operating configuration and the rest configuration).
