Description

Description of a utility certificate application on behalf of: LUMSON S. P. AT . CAPERGNANICA (ITALY) The present invention relates to a device for containing a fluid substance to be dispensed according to the preamble of the main claim. Currently known devices of the aforementioned type provide a distributor cap of limited size, which extends generally only to the vicinity of a neck of the bottle which is associated with a dispensing element, itself attached to the cap. Even in the case of containers with a larger cap, the portion of the vial that remains visible represents most or all of the side surface of the vial. With such known containers it is not easy to decorate or print text on the visible part of the side wall of the bottle. This problem has however been solved by providing a distributor cap having a top wall and a side skirt, the latter having an outer surface sufficient to apply decoration or print a text.

But this type of dispensing cap, which generally has a diameter comparable to that of the bottle, is not always guided correctly when it is actuated manually between a rest position and a dispensing position. This problem is all the more felt as the diameter of the cap is large. The purpose of the present invention is therefore to provide a device for containing a fluid substance to be dispensed which facilitates the actuation of the distributor cap between its operational positions, whatever its diameter. Another object of the present invention is to provide a device for containing a dispensable fluid substance on which it is easier to apply decoration and / or print text. These and other objects are achieved by providing a device for containing a fluid dispensing substance made in accordance with the technical teachings of the appended claims. Other features and advantages will be evident from the description of a preferred but not exclusive embodiment of the device for containing a fluid substance to be dispensed, illustrated by way of example and therefore not limiting in the attached drawings, in which FIG. 1 is a schematic perspective view in partial section of a first embodiment of the innovation, in a first operational position; Figure 2 is an enlargement of the detail indicated by the circle A in Figure 1; Figure 3 is an axial sectional view of the device of Figure 1, in the first operational position; Figure 4 is an enlargement of the detail indicated by the circle B in Figure 3; Figure 5 is a schematic perspective view in partial section of the first embodiment of the innovation, in a second operational position; Figure 6 is an enlargement of the detail indicated by the circle C in Figure 5; Figure 7 is an axial sectional view of the device of Figure 5, in the second operational position; Figure 8 is an enlargement of the detail indicated by the circle D in Figure 7; Figure 9 is a perspective view of a dispensing cap of the first embodiment of the device object of the innovation; Figure 10 is a schematic axial sectional view of a variant of the first embodiment of the innovation, in the first operational position; Figure 11 is a schematic axial sectional view of a second embodiment of the innovation, in the first operational position; Figure 12 is an enlargement of the detail indicated by the arrow E in Figure 11; Figure 13 is a schematic axial sectional view of the second embodiment of the invention, in the second operative position; A first embodiment of the device for containing a fluid substance to be dispensed is illustrated in FIGS. 1 to 9. Such a device comprises: a member 1 for dispensing said substance; a dispensing cap 2 associated with a mouth of supply lA said organ 1 for distribution and having a 2D dispensing mouth, - and a bottle 3 containing said substance and with which is associated said member 1 for distribution. According to the innovation, the substance contained in the vial 3 can be of any type, but preferably this substance is a cream. The organ 1 for the distribution of the substance contained in the bottle 3 may be of any known type, such as for example a valve adapted to deliver a fluid under pressure or a pump. In Figures 1, 3, 5 and 7 is illustrated, by way of non-limiting example, a pump of the type described in the patent U58.631.976 used in combination with a bag 4 to be inserted into the bottle 3 and suitable for contain the substance to be dispensed (the bag may, for example, be of the type described in patent application EP13177197). The bottle is also of conventional type for those skilled in the art and preferably has a cylindrical body, with a side wall 30 and a bottom wall 3A, preferably said body has, in cross section, a regular polygon shape, and even more preferably a circular shape; the bottle preferably comprises a neck 3B also conventional type. In the context of the present invention, a bottle is any type of container adapted to contain the substance to be dispensed. The material with which the bottle is made is for example plastic or glass. The dispensing member 1 is associated with the bottle 3 in any conventional manner for those skilled in the art. In the example illustrated in Figures 1 to 8 is used a base 5 which comprises a lower member 6 and an upper member 7, for example associated with each other by snapping. In the illustrated example, the lower element 6 of the base 5 is a tip member comprising a base wall 6A having an extension substantially perpendicular to a central axis M of symmetry of the container, and from which develops, in the direction substantially perpendicular to the base wall 6A and downward, an outer wall 6B. The tip member 6 is associated with the bottle 3, in particular with the neck 3B of the bottle 3, through connection means adapted to interact with counter means provided at the neck 3B of the bottle 3. In the example illustrated, the connecting means of the tip member 6 comprise a thread at the inner surface of the outer wall 63 of the tip member 6, and the connection means provided on the neck 3B of the bottle 3 comprise a thread, at the outer surface of the neck 3B, adapted to interact with the thread of the side wall 6B of the tip member 6. It is obvious to those skilled in the art that the tip member 6 can be associated with the neck 3B of the bottle 3 by other conventional means, such as crimping or snapping. The distributor cap 2 comprises at least one side skirt 2A and an upper wall 23. Preferably, the distributor cap 2 has a substantially hollow, cylindrical body open at a lower end, preferably having a regular polygon-shaped cross section. , and even more preferably in the form of a circle.

Preferably at least one end portion of the skirt 2A of the dispenser cap 2 has the same shape as the side wall 30 of the bottle 3 and has a dimension such that it can slide on the outer face of at least a portion of the lateral wall 30 of the bottle 3. Advantageously the dispensing cap 2, during its setting in motion between a rest position P2 and a distribution position P1 and vice versa, slides along at least one portion of the side wall 30 of the bottle 3. The distributor cap 2 has, in its inner part and preferably at its upper wall 2B, a tubular sleeve 2C connected to a channel 2E which opens into the 2D distribution mouth. The tubular sleeve 20 is adapted to be associated, in a manner conventional to those skilled in the art, to the feed mouth 1A, which is preferably part of a movable rod 1B of the dispenser member 1. Preferably the cap distributor 2 has in its inner part a guide wall 2F (FIGS. 3 and 7) capable of cooperating with a guiding against wall 7A of the upper element 7 of the base 5.

The distributor cap 2 is movable between: at least a first operating position P1 (FIGS. 5 to 8 and 13) in which the substance contained in the bottle is dispensed, and preferably a predefined quantity of said substance, dosed by the dispensing member; and a second operating position P2 (FIGS. 1 to 4 and 10 to 12) in which there is no said distribution of said substance. In a conventional manner for the skilled person, the distributor cap 2 is associated with the dispensing member 1 so as to be manually actuated between the two aforementioned operational positions. It is preferable that the actuation of the distributor cap 2 between the two aforementioned operating positions is a translation coaxial with a central axis M of symmetry of the container. As indicated above, at least a lower portion of the skirt 2A of the distributor cap 2 is capable of sliding externally on at least one section of an external surface of said side wall 3C of the bottle 3 during its actuation between said two operational positions (P1 , P2). According to the present invention, the device for containing a substance to be dispensed comprises at least one guide element 8 adapted to guide the sliding of the side skirt 2A of the distributor cap 2 between the two operational positions P1, P2. The guide element 8 has an outer guide surface 8A adapted to come into contact with the inner surface of the side skirt 2A, the inner surface of the side skirt 2A and the outer surface 8A having a corresponding shape. Advantageously, the outer guide surface 8A is vertical and parallel to the inner surface of the lateral skirt 2A of the distributor cap 2. The outer guide surface 8A has a transverse dimension D1 substantially equal to the transverse dimension D2 of said inner surface of the side skirt 2A. In the context of the present invention, essentially equal means that the difference that can exist between the transverse dimension Dl and the transverse dimension D2 does not exceed 1 mm. In this way, the outer guide surface 8A of the guide element 8 is always less than 1 mm from the inner surface of the side skirt 2A (FIGS. 2, 4, 6 and 8), thus preventing excessive misalignment important that could interfere with the actuation of the distributor cap 2, in particular since the second operational rest position P2 to the first operating position 21 distribution. According to the preferred embodiment of the device, the guide element 8 is provided on the outer wall 6B of the tip member 6 to be associated with the neck 3B of the bottle 3. This situation is indeed preferable, because the tip member 6 is generally made of plastic material, by embossing. As a result, the guide member 8 is produced with good accuracy. More specifically, in the preferred embodiment, the guide member 8 is located at the upper end of the outer wall 6B. According to an advantageous embodiment of the innovation, the guide element 8 comprises a stop element 9 able to come into contact with at least one abutment element 2G provided on the internal surface of said lateral skirt 2A, so as to to block the stroke of said side skirt 2A upwards when it is in said second operational rest position P2. In the example of Figure 9 the distributor cap 2 is provided with a plurality of abutment members 2G regularly distributed along an annular path on the inner surface of the side skirt 2A. Other types of abutment elements 2G are of course conceivable, such as for example a continuous circular bead projecting from the internal surface of the side skirt 2A, or due to a circular recess provided in the internal surface of the side skirt 2A. (Figs 10 to 13). It is possible to provide that the stop element 9 is provided at a different location on the device than on the guide element 8, for example on another portion of the outer wall 6B of the tip member 6, or again on the outer wall of the bottle 3. Figure 10 illustrates a variation of the preferred embodiment of the innovation. In this same FIG. 10, the elements common to the previously described embodiment retain the same reference number, to which a prime sign is added. According to the variant illustrated in Figure 10, the guide member 8 'is provided at the lower end of the outer wall 6'B of the tip member 6'. In the illustrated example, a portion of the inner surface of the side skirt 2'A has a recess which accommodates the guide element 8. The lower edge of the recess forms the abutment element 2G. Preferably, the guide element 8 provides a rounded upper portion 8B, to facilitate the guiding of said side skirt 2A. Preferably, the guide member 8 has an annular shape so that it can be practically in contact with the side skirt 2A along an entire cross section of its inner surface. In this case, the guiding surface 8A extends over the entire circumference of the guide element, and is preferably always vertical and parallel to the inner wall of the skirt 2A of the distributor cap 2. This results in a more precise guide. specific. The operation of the device according to the present invention is obvious to those skilled in the art based on the foregoing description, and in particular is as follows. After assembling the base 5 with the pumping member 1, and possibly with the bag 4, and having associated with the neck 3B of the bottle 3, the dispensing cap 2 is placed on the assembly to be associated with the mouth supply lA of the pumping member. The lower portion of the side skirt 2A of the distributor cap 2 slides along the upper portion of the outer wall 6B of the tip member 6 until the abutment member 2G abuts against the upper portion 8B of the 8 At this time, the axis of symmetry of the distributor cap 2 is already aligned with the axis M of symmetry of the bottle, and the sleeve 2C is aligned and ready to be associated with the feed mouth LA of the pumping member 1. Similarly, the inner guide wall 2F of the distributor cap 2 is ready to be inserted opposite the guide wall 7A of the upper element 7 of the base 5. The user presses on the upper wall 2B of the distributor cap 2 coaxially with the axis M of the bottle, so as to slide the abutment member 2G along the upper portion 8B and the guide surface 8A of the guiding element 8. The distributor cap 2 is thus associated with the pumping member 1 and with the snap-in device, and is in its second operative rest position 22 (Figures 1 to 4). Then, in a conventional manner, the user only has to exert pressure on the top wall 2B of the dispensing cap 2 to bring it into its first operational distribution position P1 of the substance for taking and dispensing a dose of the substance contained in vial 3 (possibly in sachet 4). During this actuation of the distributor cap 2, the lower portion of the internal surface of the side skirt 2A of the distributor cap 2 slides along the guide surface 8A of the guide element 8, and is thus guided in a direction parallel to to the axis of symmetry M of the bottle. In the same movement, the internal guide wall 2E 'of the distributor cap 2 slides against the guiding against wall 7A of the upper element 7 of the base 5. Once the distribution of the finished substance, the distributor cap 2 is brought back into its second rest operational position 22 under the effect of the pumping member 1. The upward stroke is then blocked by the reciprocal abutment which operates between the abutment element 9 and the counter element 2G abutment provided on the inner surface of the side skirt 2A of the distributor cap 2. A second embodiment of the device according to the innovation is illustrated in Figures 11 to 13. In these figures, the elements common to the first form of In this second embodiment, the guide member 108 is provided on the outer wall 1030 of the bottle 103. In this way, the innovation can be a applied to devices in which the guide element can not be provided on the tip member 106 of the base 105, for example because the tip member 106 has a transverse dimension smaller than the transverse dimension of the skirt lateral 102A of the dispenser cap 102.

This embodiment is, however, less preferred than the first, because if the vial 103 is glass, it is produced by blowing. This results in less precision in the production of the guide element 108.
