Abstract
ABSTRACT OF THE DISCLOSURE
The present invention relates to an inhalation tube for an aerosol container comprising a tubular body adapted for detachable fitting to an aerosol container. On said tubular body a delivery mouth-piece is fitted which is movable between retracted and extracted positions. The extraction and retraction of said mouth-piece is brought about by means of a cap, rotatably mounted on the tubular body, which cap has actuating means associated therewith. The cap and tubular body have openings of similar dimensions. Rotation of the cap to bring the openings into register causes the actuating means to move the mouth-piece to an extracted position, whilst rotation of said cap to bring the openings out of register causes the actuating means to move said mouth-piece in a retracted, closed-off position wholly with the tubular body. Such an arrangement enables simple functioning of the inhalation tube and ensures that hygienic conditions are provided insofar as the mouth-piece is closed-off when not in use.

1 BACKGROU~D OF T~IE INVENTION
The present invention generally relates to inhala-tion -tubes for aerosol containers, and more parti.cularly to an inhal-ation tube for inhaling medicinal products which is functional both from a hygienic and aesthetic point of view, As is ~nown, for many years aerosol containers con-taining medicinal spray products of every type and na-ture have been available. The product is sprayed through an inhala-tion tube which is manufac-tured in a variety of different shapes and conformations, the purpose of the tube being to deliver the sprayed product as a mist (aerosoll or as a wet jet (spray) into the mouth, nose, ear or other appropriate parts of the human body~
- Such inhalation tubes are referred to as inhalers and are generally provided with a closure cover for the tube opening through which the product is sprayed, so as to protect the in-ternal orifice of the valve, thereby preventing foreign matter from entering the tube, which is also promoted by the fact that the inner walls of the inhalation tu~e are generally sprayed with solvents and basic product after every use.
It should be readily understood that the cleanliness of an inhaler is not only a matter of aesthetics, but is also required for hygienic specifications, which must be scrupulously met, It should also be understood that, for example, in the case of an asthmatic product, the presence in the inhaler o~
any foreign ma-tter is completely counter-productive to an effective cure~
An objec-t of the present invention is to obviate, or at least substan-tially reduce, the above men-tioned disadvantages 1~ ~
~5 L 7 1 L~L
by providing an inhal.a-tion tube for an aerosol container which permits those parts which come into contact with the sprayed product to be closed o:EE when not in use, thereby ensuring abso--lutely hygienic conditions Another object of the invention is to provide an in-halation tube which can be moved between open and closed positions ~ithout the need for addi-tional closure means separa-te from the inhalation tube.
A further object of the invention is to provide an inhalation tube with c]..osing and opening means which result in a structurally simple arrangement and which, in addition, does not give rise to any problems in operation.
A further object of the present inven-tion is to pro~
vide an inhalation tube which, because of its particular struct-ure, is able to provide the amplest of guarantees for safety and reliability in use, A further object of the present invention is to pro-~ide an inhalation tube which is readily constructed from ele~
ments and materials normally available cn the market to enable it to he competitive from an economic point of view.
According to the invention, an inhalation tube for an aerosol container comprising a tubular body for de-tachable fit-ting to an aerosol container, is characterised in that a cap is mounted on said tubular body for rotation thereabout, that a delivery mouth-piece is mounted so as to be movable with respect to said tubular body and said cap, the tubular body and the cap each presenting an opening of subs-tantially of the same dimen-sions, and that the mouth-piece is arranged for movement by actuating means in such a manner that by rotation of the cap to bring said openings into register, -the mouth-piece is moved to an extracted position hy said ac-tuating means and, by rotation of the cap to bring said openings out o~ register, the mouth-piece i5 moved to a retractecl closed ofE, wholly within the tubular body.
~hese and other features and advantages o-E khe invention will be readily understood from the detailed descrip-tion of some preferred em~odiments, given by way of example and not intended in a limiting sense, of an inhalation tube with an extractable and retractable mouth-piece with reference to the accompanying drawings, ~herein: .
Figure 1 is a cross-sectional view o~ the first embodi-ment of the inhalation tu~e with the mouth-piece in a retracted position, Figure 2 is a cross-sectional view of the inhalation tube of Figure 1 with the mouth~piece in an extracted position, Figure 3 shows the first embodiment sectioned-through the hinging pin of -the mouth-piece, Figure 4 is a secti.onal view taken along the line IV-IV of Figure 2, Figure 5 is a cross-sectional view of the second emhodiment of inhalation tube with the mouth-piece in a retracted position, Figure 6 is a cross-sectional view of the embodiment shown in Figure 5 with the mouth-piece in an extracted position, Figure 7 is a sectional view of the emhodiment shown in Figure 5, taken through the hinging pin of the mouth-piece, Figure 8 is a sec-tional view taken along the line VIII-VIII of Figure 6, Figure 9 is a cross-sectional view of the third embodi-ment of inhalation tu~e with the mouth-piece in a retracted position, Figure 10 is a cross-sectional view of the embodimen-t shown in Figure 9 with the mouth~piece in an extracted position, Figure 11 is a sectional view taken along -the line XI-XI of Figure 9, Figure 12 is a sectional view of Figure 10 taken along the line XII-XII showing all the inhalation tube wi-th the mouth-piece in an extractea position, and Figure 13 is a front elevational view of the various em~odiments of inhalation tube.
With reference to the above mentioned figures, there is illustrated an inhalation tube with opening and closing of an extractable and retractable portion, which is shown in three different embodiments, substantially similar to one another.
Referring to Figures 1 to 4 the first embodiment of inhalation tube comprises a tu~ular body 1 of an elongated sub-stantially cylindrical shape, defining at its upper portion a first opening 2, extending along a peripherical segment.
From the internal upper wall of the body 1 a hollow shank 3 extends in a su~stantially axial direction and is pro-vided with a delivery orifice 4 (see Figure 4), said hollow shank being detackably fitted on the protruding stem of a valve 5 of an aerosol container 6, which can contain any one of the products normally availa~le on the market including non-medicamentous substances.
At the first ahove mentioned opening 2 a delivery mouth-piece 7 of a suita~le shape is provided.
The delivery mouth-piece 7 is h.inged to allow its piv-otal movement about a pin 8 secured to the internal wall of said tubular body 1.
3 n In accordance with the invention, the delivery mouth-piece 7 at the region hinged to the pin 8 is provided with a 1 resilient strip 9. which acts hy reaction against the internal wall of the tubular ~ody 1 to tend to rotate the mouth-piece 7 to an outward position in a manner ~hich will be described here-ina~ter.
Associated ~ith the tubular body 1 is a cap 10 which is mounted for rotation about the axis of the body 1 and is pro-vided with a second opening 11 adapted to be brought into reg-ister with the first opening 2 in o:rder to permit the extraction of the mouth-piece 7.
~0 In more detail, it can be seen that ~y rotating the cap 10, once the second opening 11 comes into register with the first opening 2, the mouth-piece 7, is urged by the resilient strip 9, which acts like a spring, to rotate it outwardly to assume the position shown in Figure 2 It is to be noted that the mouth-piece 7, on the side opposite to its hinge axis has a stop projection, adapted to a~ut the internal wall of the cap 1~ to ensure the correct extracted position of the mouth-piece 7.
To retract the mouth-piece 7 all that is necessary is to rotate the cap 10 counterclockwise, so that! by rotating about the pin 8 and overcoming the spring reaction of the resilient strip q, it retracts into the tubular body 1. When retraction has ~een completed, the firs-t opening 2 is closed by the internal wall of the cap 10, thus preventing extraction of the mouth-piece and also preventing the infiltration thereinto of any substance which could contaminate the mouth-piece, ~ eferring to Figures 5 to 8 showing the second embodi-ment of inhalation tube, those elements which corresponcl to ele-ments of the first embodiment are given the same reference numbers.
In this embodimen-t the mouth-piece 7 is not provided with a resilient strip but instead its rotation is obtained by a camming 1'7~
means 20 coupled -to the cap 10 and passing -through a cu-tout 21 provided in the upper portion OL the tubular body 1. Thus, when the cap 10 is rotated to bring the openings 2 and 11 in-to register, the camming means 20 first acts on the rear por-tion of the mouth-piece 7 and extraction of the latter is completed by the action of the adjacent side edge of the opening 11 .
~ s shown in the figures, the CUtOIlt 21, which is suit-ably shaped as a circular segment Cshown chain-dotted in Figures 5 and 6) acts as a stop at its opposite radial sides For the retracted (Figure 5~ and -the extracted positions (Figure 6) of the mouth-piece 7. Retraction of the mouth-piece 7 is effected by the action of the other side edge of the opening 11 upon counterclockwise rotation of the cap 10.
Referring to Figures 9 to 13 in the third embodiment of inhalation tu~e the mouth-piece 7 is not hinged to the tu~ular body 1~ but is supported therein in such a ~ay that it can ~e moved in a radial direction with respect to the axis ~f the tubular body 1, this movement being guided by engagement of the mouth-piece 7 with the hollow shank 3 via a slot 30. The extraction movement is effec-ted by an elastic element 31 which is supported at its opposite ends by the walls of the mouth-piece 7 and engages said hollow shank 3.
In more detail, when the cap 10 is rotated to bring the first and second openings 2, 11 in register, the mouth-piece 7 is urged outwardly by the elastic element 31 until its stop projections 32 abut -the internal walls of tubular body 1 to cor-rectly position the mouth-piece 7 in its extracted position and, of course, to prevent it falling out of tubular body 1, which is very undesirable. For extraction, all that is necessary is to 7~4 1 rotate the cap 10 so that, taking advan-tage of the particular rounded shape o~ the sides of the mouth-piece 7, a ra~ial pushing action is exerted on the mouth-piece 7, which moves the latter inwardly to overcome the spring bias action exerted by the elas-tic element 31, From the above, it will be appreciated that for all the descri~ed embodiments both the extraction and the retrac-tion of the delivery mouth-piece 7 is achieved in a very simple manner merely by appropriate rotation o~ the cap 10~
Furthermore, the rotation of cap 10, in addition to controlling the retracted ana extracted position of the mouth-piece 7 into -the tubular body 1, also ensures that in the re-tracted position of the mouth-piece 7, any communcation with the exterior of the tubular body 1 is prevented, thus giving the highest guarantees of safety and hygiene.
It will also be appreciated that the embodiments de-scribed a~ove achieve the objects discussed hereinbefore. Thus, for example, no separate elements are necessary to close the in-halation tube, since the closing means, as already mentioned, are incorporated in the cap 10.
Of course, the invention can be su~jected to many mod-ifications and changes within its scope. Many alterations can be made thereto and all de-tails can be substituted for other tech-nically equivalent elements without departing from -the scope of the inveniton.
Practically, the materials used, provided that are suitable to the specific use, as well as the dimensions and shapes can be adapted to meet any particular requirement.
