With reference to the accompanying figures, the present invention relates to a refillable dispenser 1 for pasty or semi-liquid products, in particular for toothpaste.
As used herein, pasty or semi-liquid products refer to any substance having a semisolid or semi-liquid consistency such as creams, gels, cosmetic products, detergents, food sauces and glues.
A first embodiment of the present invention particularly relates to a refillable travel dispenser 1, i.e. a refillable dispenser 1 configured to be easily transported and stored for example in a vanity case or a bag.
A second embodiment of the present invention relates to a refillable bench dispenser 1, i.e. a refillable dispenser 1 configured to stand on a flat surface, such as the surface of a sink or a bench.
Particularly referring to Figures 1, 2, 7 and 8, the refillable dispenser 1 of the present invention comprises a container 2 extending between a first end and a second end 21, 22 aligned along a longitudinal direction X-X.
In the first embodiment the container 2 is deformable and is preferably made of flexible plastic material, such as plastic or high-density polyethylene laminates.
In the first embodiment, the first and second ends 21, 22 are aligned along the longitudinal direction when the container 2 is not deformed.
The container 2 has a cavity 20 configured to receive a cartridge 4 containing a given amount of pasty or semi-liquid product. Further details about the cartridge 4 will be provided hereinbelow.
Preferably, the cavity 20 extends in the longitudinal direction X-X from the first end 21 to the second end 22.
Preferably, in the first embodiment, the container 2 is a tube having an enclosure made of flexible plastic material, which extends in the longitudinal direction X-X between the first and second ends 21, 22.
The first end 21 has a mouth 23 configured to allow the outflow of the pasty or semi-liquid product contained in the cartridge 4. More in detail, the mouth 21 comprises a through hole which extends through the mouth 23 to provide fluid communication of the cavity 20 with the outside.
Preferably, the mouth 23 and the through hole extend from the first end 21 along the longitudinal direction X-X in a direction away from the second end 22.
The mouth 23 of the first end 21 is configured to be associated with an opening 40 of the cartridge 4, to allow the outflow of the product in the cartridge 4 when pressure is applied on the container 2. In other words, the through hole of the mouth 23 is configured to be connected in fluid communication with the interior of the cartridge 4 via the opening 40.
In operation, a user applies a pressure on the container 2 which deforms and hence pushes the product in the cartridge 4 out through the mouth 23.
The refillable dispenser comprises a cap 3 adapted to be reversibly coupled with the mouth 23 to close it. More in detail, as the cap 3 is coupled with the mouth 23, it closes the through hole that allows the outflow of the product in the cartridge 4. The reversible coupling between the cap 3 and the mouth 23 may be provided, for example, by means of a threaded connection, a bayonet connection, or any other type of known reversible mechanical connection.
The second end 22 of the container 2 is adapted to be opened to allow removal and/or introduction of the cartridge 4 from/into the cavity 20. In other words, the second end 22 is configured to allow replacement of the cartridge 4 once its contents have been completely emptied.
In the first embodiment as shown in Figures 1 and 2, the second end 22 comprises a first edge and a second edge 22a, 22b, which are opposite and movable relative to each other to open and close the second end 22 of the container 2.
The edges 22a, 22b extend transverse, preferably perpendicular, to the longitudinal direction X-X, and are connected to each other at their terminations 220, as shown in Figure 2.
In addition, the edges 22a, 22b are adapted to be reversibly fixed against each other. In practice, when the second end 22 is closed, the first and second edges 22a, 22b abut each other to close, and when the second end 22 is open, the first and second edges 22a, 22b are spaced apart and only connected at their terminations 220.
More in detail, when the second end 22 is open, the first and second edges 22a, 22b are spaced apart to define a refill opening 24 which is designed to provide communication between the cavity 20 and the outside. The refill opening 24, and the first and second edges 22a, 22b are suitably sized to allow insertion and/or removal of the cartridge 4 into/from the cavity 20.
Preferably, the refillable dispenser 1 comprises a closure device 5 configured to seal the second end 22 of the container 2 and keep it closed.
Referring to Figure 2, the closure device is integrated in the second end 22 of the container. More in detail, the closure device 5 comprises a groove 50 extending along the first edge 22a of the second end 22, and a projection 51 facing the groove 50 and extending along the second edge 22b of the second end 22.
Preferably, the groove 50 and the projection 51 extend transverse to the longitudinal direction X-X to thereby connect the ends 220 of the edges 22a, 22b. More preferably, the groove 50 and the projection 51 extend perpendicular to the longitudinal direction X-X.
The groove 50 and the projection 51 are configured to be reversibly coupled to allow the second end 22 of the container 2 to be opened and closed.
The second end 22 is closed when the projection 51 is received within the groove 50 to form an interference fit, and is open when the projection 51 and the groove 50 are spaced apart.
In order to open the second end 22, the user must separate the edges 22a, 22b by exerting a pulling force thereon to remove the projection 51 from the groove 50. Likewise, in order to close the second end 22, the user must press one edge against the other 22a, 22b to accommodate the projection 51 in the groove 50.
Alternatively, referring to Figure 4, the closure device 5 is a device configured to be placed at the second end 22 to keep it closed.
More in detail, as shown in Figure 4, the closure device 5 comprises a pair of opposable pressing surfaces 52 which can be commuted between a first closed configuration in which the pressing surfaces 52 are close together and press the edges 22a, 22b of the second end 22 against each other, and an open configuration in which the pressing surfaces 52 are spaced apart.
Preferably, the closure device 5 comprises a hinge 53 for pivotally constraining the pressing surfaces 52 about a hinge pivot axis C-C, as shown in Figure 4. As the pressing surfaces 52 rotate relative to each other about the hinge pivot axis C-C they are commuted between the closed and open configurations.
Furthermore, preferably, still with reference to Figure 4, the closure device 5 comprises a closing mechanism 54 which is configured to keep the pressing surfaces 52 close together in the closed configuration.
Preferably, the closure device 5 also has a safety function, in that, if the cartridge 4 is punctured or broken, it prevents its contents from escaping from the second end 22 of the container 2. In other words, the closure device 5 is equipped with means adapted to close the second end 22 of the container 2 in a fluid-tight manner to prevent the contents of the cartridge 4 from escaping whenever the latter is accidentally broken.
Preferably, the refillable dispenser 1 comprises a squeezing device 6 which is configured to assist the user to eject the pasty or semi-liquid product from the cartridge 4 by keeping it under pressure.
In the first embodiment, the squeezing device 6 can be applied between the first and second ends 21, 22 of the container 2 and is configured to slide, as the product is being used, from the second end to the first end 22, 21. More in detail, as the squeezing device 6 sliding from the second end to the first end 22, 21, it deforms the container 2 and causes the product contained in the cartridge 4 to flow out of the mouth 23.
In the first embodiment of Figure 5, the squeezing device 6 comprises a C-shaped main body 60 specially sized to compress the container 2 on opposite sides, thereby deforming it.
Advantageously, the squeezing device 6 facilitates the user to deform/squeeze the container 2 of the refillable dispenser 1 to extract the pasty or semi-liquid product from the cartridge 4.
Preferably, the refillable dispenser 1 comprises a lock system 7, which is adapted to prevent the squeezing device 6 from moving from the first end to the second end 21, 22, when the squeezing device 6 is applied between the first and second ends 21, 22 of the container 2.
More in detail, in the first embodiment of Figures 1 and 2, the lock system 7 comprises a textured guide 71 extending outside the container 2 between the first and second ends 21, 22 along the longitudinal direction X-X.
In addition, the lock system 7 comprises a slider 72 configured to slide in the textured guide 71 from the second end to the first end 22, 21. As shown in Figure 5, the slider 72 is placed on the main body 60 of the squeezing device 6, so that when the squeezing device 6 moves from the second end to the first end 21, 22 of the container 2, the slider 72 will slide in the textured guide 71 and prevent any back movement of the squeezing device 6.
Referring to Figure 6, the slider 72 and the textured guide 71 has each a plurality of complementary shaped teeth which ensures a one-way relative movement thereof, here coinciding with that the direction from the second end to the first end 22, 21.
The second embodiment of Figures 7, 8 is similar to the first embodiment of Figures 1 and 2, but with a rigid container 2.
More in detail, the container 2 of the second embodiment comprises a pair of half-shells 25 that are designed to be coupled together to define the cavity 20 that is adapted to contain the cartridge 4.
The half-shells 25 are movable to commute the refillable dispenser 1 between a use configuration in which the half-shells 25 abut against each and define the cavity 20, and a refill configuration in which the half-shells 25 are spaced apart to allow the user to access the cavity 20, e.g. to replace the cartridge 4 or clean it.
Preferably, the container 2 comprises a plurality of hinges 26 which are adapted to pivotally constrain the half-shells 25 about an axis of rotation R-R. As the half-shells 25 respectively pivot about the axis of rotation R-R, they commute the refillable dispenser 2 between the use configuration and the refill configuration. The use configuration is shown in Figure 8, whereas the refill configuration is shown in Figure 7.
In the second embodiment, the squeezing device is configured to deform the cartridge 4 so that the product contained therein will flow through the opening 40 of the cartridge 4 and out of the mouth 23.
More in detail, the squeezing device is mechanically operable by means of a manual pressure mechanism 62 located on a half-shell 25, otherwise, in alternative embodiments, it is driven with the same principle by an electric motor that can be actuated by means of a push-button 61 located on the container 2.
Referring to Figure 8, if the refillable dispenser 1 is configured to dispense toothpaste, then the container 2 may comprise, at the mouth 23, a support surface 27 for supporting a toothbrush 100.
Furthermore, the present invention relates to a kit comprising a refillable dispenser 1 for pasty or semi-liquid products as discussed above, and a cartridge 4 containing the pasty or semi-liquid product.
More in detail, the cartridge 4 is configured to reversibly fit into the cavity 20 of the container 2 through the second openable end 22. Even more in detail, in the first embodiment, the cartridge can be inserted and removed into/from the cavity 20 of the container 2 through the refill opening 24 defined by the first and second edges 22a, 22b of the second end 22 when they are spaced apart.
The cartridge 4 is deformable and has a pocket 41 adapted to receive the pasty or semi-liquid product, and is preferably made of a flexible plastic material.
The cartridge 4 has a bottom 42 that closes the bottom of the pocket 41. In the first embodiment, the bottom 42 is configured to be locked between the first edge and the second edge 22a, 22b of the second end 22, when the cartridge 4 is fitted in the cavity 20 and the second end (22) is closed.
In the second embodiment, the bottom 42 is configured to be locked between the first edge and second edge 22a, 22b of the second end 22, when the cartridge 4 is fitted in the cavity 20 and the second end 22 is closed as the half-shells 25 are coupled together.
The bottom 42 of the cartridge 4 may be formed, for example, by heat-sealing.
The cartridge 4 also has a top 43 comprising an opening 40 configured to cause the contents of the pocket 41 to flow out of the cartridge 4. As mentioned above, the opening 40 of the cartridge 4 is configured to be associated with the mouth 23 of the container when the cartridge 4 is fitted in the cavity 20.
The opening 40 is closed by a removable tab 44 configured to prevent the pasty or semi-liquid product from flowing out of the pocket 41 before insertion into the cavity 20.
The removable tab 44 must be removed manually by the user before fitting the cartridge into the cavity 20 of the container 2.
