STOPPER FOR BOTTLES OR RECEPTACLES OF VARIOUS
KIND
DESCRIPTION
The present invention refers to a stopper for bottles or vessels of various kind holding wine, spirits, alcoholic and hydroalcoholic substances and beverages of various kind, edible oil, and the like, said stopper being adapted to plug and seal such bottles or other vessels of various kind so as to ensure long-term preservation of the contents thereof while preventing them from coming into contact with the ambient air, and being further adapted to be removed for gaining access to the contents of such bottles or other vessels of various kind, wherein fitting and removing this stopper can be done in a very simple and quick manner.
Largely known in the art are plugs and stoppers of different kinds and materials (such as for instance cork, plastics, metal, etc.) intended for closing bottles and other vessels holding wine, spirits, alcoholic and hydroalcoholic substances and beverages of various kind, oil, and the like, which are generally made up by a substantially cylindrical body adapted to be fitted into the inlet hole of the neck of a bottle, or a related vessel, and which are usually press-fitted into said inlet hole so as to seal in an air-tight manner the related bottle or other kind of vessel, as the case may¬ be, for the desired period of time during which the wine, spirit, alcoholic or hydroalcoholic substance, oil, etc. contained in such bottle or other kind of vessel, as the case may be, has to be preserved there, such stoppers being then removed, i.e. pulled out, with the help of appropriate corkscrews or other drawing implements of a more or less traditional kind, when the contents of the bottles or other kind of vessels, as the case may¬ be, is eventually due to be used or served for drinking.
The present invention refers to a stopper for plugging bottles or vessels of various kind holding wine, spirits, alcoholic and hydroalcoholic substances and beverages of various kind, edible oil, and the like, which is provided in a different, novel manner as compared with prior-art stoppers of the currently used types, so as to be able to be applied to and removed from the bottle or vessel, as the case may be, in a quick, convenient and simple manner, through just a few handlings and without requiring the help of any corkscrew or similar drawing implements as they have been used hitherto to such purposes.

In the case being considered, use is made of a bottle 11 , which is partially illustrated in the various Figures, and which is shaped to feature an upper neck portion 12 delimiting an inlet hole 13, which gives into the interior volume of the same bottle, and provided with an external thread 14 at the upper terminal portion thereof.
Referring now to Figures 1 to 4, in which the inventive stopper is illustrated in a first embodiment thereof, it can be noticed that it is substantially comprised of a stopper body 15, which is adapted to close the mouth portion of the neck 12 of the bottle 11 in an air-tight manner, and a covering cap 16 capable of being fitted on and removed from the stopper body 15 in the manner and to the purpose that shall be described in greater detail below. Particularly, the stopper body 15 is provided with an appropriately- shaped upper portion 17 and an equally appropriately shaped lower portion 18 that are joined with each other, of which the upper portion 17 is formed of at least two thin planar circular disks 19 and 20 that are slightly spaced from each other axially and are joined to each other via a curved surface 21, whereas the lower portion 18 is formed of a cylindrical middle body 22 joining the bottom side of the lower circular disk 20 and projecting downwards therefrom to eventually terminate into a tapered lower end portion 23, wherein such middle body 22 and such tapered end portion 23 are so sized as to be able to compliably fit into the inlet hole 13 of the neck 12 of the bottle 11. The stopper body 15 is preferably provided with the upper portion 17 thereof that is made of a plastic material and the lower portion 18 thereof that is made of natural cork; however, as already hinted hereinbefore, it can also be made of other, different materials or it can be made to be comprised of just a single and same material, such as plastics, cork, metal, etc.
In turn, the covering cap 16 (see Figure 2) is comprised of an elongated cylindrical body 24 delimiting an inner cavity 25, which is open below and is closed on top by a planar sealing wall 26, wherein such inner cavity 25 is provided with a thread 27 extending along most of the length dimension thereof, said thread being adapted to be screwed on and unscrewed from, i.e. threadably engage and disengage the corresponding external thread 14 provided on the neck 12 of the bottle 11, and said upper sealing wall 26 being provided as a single-piece unitary construction with a cylindrically shaped upper cap portion 28 that joins to the elongated body 24 of the cap 16 and is provided with a diameter that is larger than the one of the same elongated body 24 and a height that is slightly greater than the one of the upper portion 17 of the stopper body 15, so as to allow said upper stopper portion 17 to compliably fit into this upper cap portion 28.
To this purpose, such mutual adaptation is obtained by shaping the inner surface of the upper cap portion 28 with a contour that is identical and symmetric to the outer contour of said upper stopper portion 17 and, in this condition, the stopper body 15 turns out as being fitted in an airtight manner into the inner cavity 25 of the covering cap 16, firmly joined thereto. In this way, as this is best illustrated in Figure 3 showing the inventive stopper inserted in the inlet hole 13 of the neck 12 of the bottle, the filling mouth of the neck portion of the bottle can be sealed in a most simple and quick manner by screwing the internal thread 27 of the covering cap 16 on the external thread 14 of the neck 12 of the bottle, whereby the middle stopper body 22 is gradually inserted in the inlet hole 13 of the neck 12 of the bottle until - when said cap 16 is fully screwed on the bottle neck 12 - the bottom planar surface of the lower disk 20 of the upper stopper portion 17 eventually comes to abut against the upper planar edge 29 of the bottle neck 12 and rests in this position in a condition in which said filling mouth of the neck 12 of the bottle 11 is closed in an air-tight manner by the stopper body 15 owing to the sealing effect produced by both the middle stopper body 22 inserted in the inlet hole 13 and the lower disk 20 of the stopper portion 17 abutting against the rim, i.e. the upper edge 29 of the neck 12 of the bottle 11. Opening, i.e. removing the stopper from the bottle can again be done in a most simple and quick manner by just repeating the above-described handling sequence in the reverse order, wherein the covering cap 16 is therefore unscrewed from the neck 12 of the bottle until the same cap is fully loosened and, as a result, the middle stopper body 22 is completely drawn out of the inlet hole 13 of the neck 12 of the bottle.
The stopper body 15 may be joined to the covering cap 16 even in manners differing from the afore-described one, e.g. by providing it in a single-piece unitary construction with the same covering cap, so as to be able to directly manufacture it in a single moulding operation, thereby avoiding the need for the two pieces (i.e. the stopper body 15 and the covering cap 16) to be first manufactured separately and then press-fitted together in the afore-described manner, whereby manufacturing these two pieces would be significantly simplified and the costs sustained to produce the inventive stopper reduced accordingly.
Referring now to Figures 5 to 7, in which the inventive stopper is illustrated in a second embodiment thereof, it can be noticed that it is still substantially comprised of the same component parts 15 and 16 as the afore-described ones, while differing from the previously described stopper in that the stopper body 15 is in this case solely provided with the upper stopper portion 17, which on the other hand is fully similar to the one described in connection with the previously considered first embodiment of the inventive stopper, whereas the lower stopper portion 18, i.e. the cylindrical middle body 22, is in this case eliminated. In this way, such upper stopper portion 17 is - as in the previously discussed case - joined to the covering cap 16 by either press-fitting the two parts together or manufacturing, i.e. moulding the assembly as a single-piece unitary construction, and when the internal thread 27 of said cap is screwed on the external thread 14 of the neck 12 of the bottle until having the cap fully screwed down, in the condition in which the bottom surface of the lower disk 20 of said upper stopper portion 17 comes into abutting against the planar rim 29 of the neck 12 of the bottle, this is again effective in plugging and sealing in an air-tight manner the filling mouth of the neck 12 of the bottle, owing in this case solely to such lower disk 20 abutting against the planar rim 29 of the neck 12 of the bottle.
Referring now to Figures 8 to 10, in which the inventive stopper is illustrated in a third embodiment thereof, it can be noticed that it is now solely comprised of a covering cap 30, which is adapted to close, i.e. seal in an air-tight manner the filling mouth of the neck 12 of a bottle 11 , and which is shaped and formed in the manner that shall be further described below, wherein such cap is capable of being fitted on and removed from said bottle neck so as to cause the bottle to be corked and uncorked, i.e. closed and opened, respectively. Even this covering cap 30 may be made with the use of similar materials as the ones employed to manufacture the previously discussed cap, and is basically provided with an elongated cylindrical body 31 delimiting an inner cavity 32, which is open below and is closed on top by a planar sealing wall 33, wherein such inner cavity 32 is provided as a single-piece unitary construction with a cylindrically shaped upper cap portion 34 that joins to the elongated body 31 of the cap 30 and has a diameter that is larger than the one of the same elongated body, as well as a height that is slightly greater than the one of the threaded portion 14 of the neck 12 of the bottle, while the inner cavity being delimited by said upper cap portion 34 is provided with a threaded portion 35 (see Figure 10) adapted to threadably engage and disengage the corresponding threaded portion 14 of the neck 12 of the bottle. In turn, the planar sealing wall 33 on top is shaped internally so as to feature a protruding circular edge or rim 36 facing the inner cavity 32 of the cap and formed in a position coinciding with the inlet hole 13 of the neck 12 of the bottle, wherein the outer surface of said protruding rim 36 is inclined with a top-down descending slope, so as to be able to come into abutting and resting against the rim around the mouth of the inlet hole 13 of the bottle neck 12 when the threaded portion 35 of said cap 30 is fully screwed down on the corresponding threaded portion 14 of the same bottle neck, thereby causing the bottle to be plugged in an air-tight manner.
Such air-tight sealing effect is also promoted by the elasticity of the protruding rim 36, which can therefore be pressed against the rim around the mouth of the inlet hole 13 of the bottle neck 12 without suffering any permanent deformation, so that, after having been pressed in this manner, such protruding rim 36 is then able to spring back into, i.e. recover the original shape and position thereof when the stopper is unscrewed and removed from the bottle.
Referring now to Figures 11 to 16, in which the inventive stopper is illustrated in a fourth embodiment thereof, it can be noticed that it is substantially comprised of a stopper body 37, which is adapted to close the mouth portion of the neck 12 of the bottle 11 in an air-tight manner, and a covering cap 38 cooperating with said stopper body 37 as this shall be described further on, capable of being fitted on and removed from the bottle neck 12 in the manner and to the purpose that shall be described in greater detail below.
The stopper body 37 is made in a single-piece unitary construction of a material of any of the afore-mentioned kinds; as this is particularly illustrated in Figures 11 and 16, it is shaped so as to feature a thin upper planar sealing wall 39 of a cylindrical shape and provided with a short cylindrical threaded portion 40, and an elongated cylindrical body 41 extending therebelow with a diameter that is smaller than the one of said upper wall 39 and the threaded portion 40, said cylindrical body being adapted to fit into the corresponding inlet hole 13 of the bottle neck 12.
In particular, the upper sealing wall 39 is solidly applied, e.g. by a so- called over- injection process, on to the upper stopper portion 42, which is firmly joined to the elongated body 41, and is formed of two planar circular disks 43 and 44 that are slightly spaced from each other axially and are joined to each other via a curved surface 45. In turn, the covering cap 38 is formed (see Figures 11 to 15) of an elongated cylindrical body 46 delimiting a through-bore 47 and made in a single-piece unitary construction with an upper cap portion 48 provided with a first upper internal threaded portion 49, in which there is capable of being screwed and unscrewed the corresponding threaded portion 40 of the stopper body 37, as well as a second lower internal threaded portion 50 that extends all along the remaining height of the covering cap 38 and is capable of being screwed on and unscrewed from the threaded portion 14 of the bottle neck 12. In this case, the threaded portion 40 of the stopper body 37 is screwed on and unscrewed from the corresponding first internal threaded portion 49 of the covering cap 38 and, when said stopper body is fully screwed down into the covering cap 38, the air-tight plugging or sealing effect is obtained owing to both the elongated cylindrical body 41 being in close contact against the inner wall of the inlet hole 13 of the bottle neck 12 and the lower circular disk 44 abutting and pressing against the planar rim 29 of the bottle neck 12.
Referring now to Figures 17 to 22, in which the inventive stopper is illustrated in a fifth embodiment thereof, it can be noticed that it is still substantially comprised of the same component parts 37 and 38 as described above, while differing from the previously described stopper in that the stopper body 37 is in this case solely provided with the upper sealing wall 39 and the upper stopper portion 42, which on the other hand are fully similar to the afore-described ones, whereas the elongated cylindrical body 41, is in this case eliminated. Moreover, even in this case the upper sealing wall 39 is provided with a short threaded portion 40 adapted to be screwed on and unscrewed from the corresponding first internal threaded portion 49 of the covering cap 38, while the air-tight plugging or sealing effect is solely obtained owing to the lower circular disk 44 abutting and pressing against the planar rim 29 of the bottle neck 12 when the second internal threaded portion 50 of the covering cap 38 is fully screwed down on the corresponding threaded portion 14 of the bottle neck 12.
Referring now to Figures 23 to 27, in which the inventive stopper is illustrated in a sixth embodiment thereof, it can be noticed that it is still substantially comprised of a stopper body 51, which is made in the way as described below, and a covering cap 38 similar to the one described in connection with the previously illustrated embodiment with reference to Figures 13 to 22, said covering cap being again provided with a first internal threaded portion 49, which cooperates with said stopper body 51, and a second internal threaded portion 50 that is capable of being screwed on and unscrewed from the corresponding threaded portion 14 of the bottle neck 12. In particular, the stopper body 51 is formed of an upper planar sealing wall 52 that is made in a single-piece unitary construction with a short cylindrical body 53 having a smaller diameter than the wall itself, which is provided with an external threaded portion 54 and an internal threaded portion 55, which are capable of being screwed on and unscrewed from the corresponding first internal threaded portion 49 of the covering cap 38 and the corresponding threaded portion 14 of the bottle neck 12, respectively. In turn, the upper sealing wall 52 is shaped internally so as to feature a protruding circular edge or rim 56 facing the inner cavity of the covering cap 38 and formed in a position coinciding with the inlet hole 13 of the neck 12 of the bottle, wherein the outer surface of said protruding rim 56 is inclined with a top-down descending slope, so as to be able to come into abutting and resting against the rim around the mouth of the inlet hole 13 of the bottle neck 12 when the second internal threaded portion 50 of said covering cap 38 is fully screwed down on the corresponding threaded portion 14 of the same bottle neck 12, and when the external threaded portion 54 and the internal threaded portion 55 of the stopper body 51 are fully screwed down on the corresponding first internal threaded portion 49 of the covering cap 38 and the corresponding threaded portion 14 of the bottle neck 12, respectively.
In the same way as in the exemplary embodiment described with reference to Figures 8 to 10, even in this case air-tight sealing of the bottle is obtained by the outer surface of the protruding circular rim 56 abutting and resting against the mouth portion of the inlet hole 13 of the bottle neck 12, when the covering cap 38 is fully screwed down on the same bottle neck 12 and the stopper body 51 is in turn fully screwed down both into the covering cap 38 and on the bottle neck 12, as described hereinbefore.
