Technical Field
[0001] The present invention relates to a multiple-dose bottle with dosage spout for products,
particularly for medicines.
Background Art
[0002] It is known that some products, such as for example medicines, if contained in multiple-dose
bottles, use preservatives in order to avoid any likely bacterial contaminations caused
by direct contact of the contained product with the surrounding air.
[0003] Currently applicable statutory provisions require, in the near future, the elimination
of these preservatives from multiple-dose bottles and this disadvantageously entails
the inadequacy of known kinds of bottle, which do not ensure complete asepsis of the
product.
[0004] As an alternative, in order to obviate this drawback of known kinds of multiple-dose
bottle, single-dose bottles which are used only once and therefore require no preservatives
are used for the dosage of these products.
[0005] However, even these single-dose bottles are not free from drawbacks, including the
fact that the asepsis of the product is ensured at the cost of wasting material, since
the single-dose bottle is discarded after a single application of the product.
[0006] A dispensing bottle suitable for storing a sterile solution is disclosed in US-A-4
739 906.
[0007] Further examples of containers provided with applicators, suitable for preserving
substances, are available from US-A-5 727 892, US-A-5 743 441 and CH-A-528 415.
Disclosure of the Invention
[0008] The aim of the present invention is to eliminate the above drawbacks of conventional
bottles, providing a multiple-dose bottle with dosage spout for products, particularly
medicines, which allows to fully eliminate the use of preservatives which are harmful
to human health, to contain an aseptic product which can be used even more than once,
and to reduce the waste of material and therefore the manufacturing and packaging
costs of bottles for an equal volume of contained product.
[0009] Within the scope of this technical aim, an object of the present invention is to
achieve the above aim with a structure which is simple, relatively easy to provide
in practice, safe in use, effective in operation and relatively cheap.
[0010] This aim and this object are both achieved by the present multiple-dose bottle with
dosage spout for products, particularly medicines, having the features set forth in
the appended claims.

Ways of carrying out the Invention
[0012] With particular reference to the above figures, the reference numeral 1 generally
designates a multiple-dose bottle for products, particularly medicines, according
to the invention.
[0013] The multiple-dose bottle 1 is constituted by a conventional bellows-like part S,
made of a material of a deformable type, and comprises a dosage spout 2 constituted
by a nozzle 3 on which a cap 4 is fitted hermetically: compression of the bellows-like
part S causes the liquid to seep between the nozzle 3 and the cap 4.
[0014] The nozzle 3 is made of substantially rigid material, is ogive-shaped and is crossed
by at least one aperture 5 for the outflow of the liquid; the cap 4 is made of flexible
material and has a dispensing port 6 formed at an external protrusion 7 which is substantially
nipple-shaped.
[0015] Advantageously, the nozzle 3 and the cap 4 are both made of a material such as plastic
and/or rubber and must be sterilizable, inert and impermeable to liquids.
[0016] In its tip region 8, proximate to the protrusion 7, the cap 4 is thinner, so as to
allow the liquid to seep between the aperture 5 and the port 6.
[0017] The cap 4 is thicker in the intermediate region 9, so as to ensure a better hermetic
clamping against the surface of the nozzle 3; said nozzle is rigidly coupled to the
mouth 10 of the bottle 1, which is in turn surmounted by the base 11 of the cap 4.
[0018] Figures 1 to 5 illustrate a first embodiment of the bottle 1 and some of its components
in detail: the nozzle 3 has two apertures 5 and the port 6 of the cap 4 is constituted
by a diametrical slit 12 on the top of the protrusion 7.
[0019] As an alternative to the slit 12, and in a manner which is fully equivalent thereto,
the port 6 might also be constituted by a star-shaped arrangement of cuts or by a
capillary tube formed on the protrusion 7.
[0020] Conveniently, a ring 13 is secured to the base of the cap 4 and is adapted to keep
the cap 4 and the nozzle 3 rigidly coupled to the mouth 10 of the bottle 1.
[0021] Figures 6 to 9 illustrate a second embodiment of the bottle 1, showing its main components:
in this case, the nozzle 3 is provided with two apertures 5 and is axially provided
with a pin 14 which is adapted to close the port 6, which in this case is constituted
by a substantially circular hole 15 of the protrusion 7.
[0022] Figure 10 illustrates an embodiment of the bottle 1 in which a ring 16 is coupled
to the mouth 10 of said bottle; said ring is connected, by conventional sealing means
17, to a hood 18 for closing the cap 4 and can be eliminated once the sealing means
17 have been removed.
[0023] In figure 13, the ring 16 is rigidly coupled to the mouth 10 and protrudes downwards
with a partial containment body 19 which is adapted to support the bottle 1 in vertical
position.
[0024] In the bottle 1 of figure 14, the ring 16 is internally provided with conventional
means for coupling to a securing ring 13 interposed between the ring and the mouth
10.
[0025] Said coupling means are generally removable and are constituted by a portion which
is coupled, by pressing or by interlocking, to the ring 13 or by a threaded portion
which can be screwed on a correspondingly threaded portion of the ring 13.
[0026] Figures 15 to 21 are views of some additional possible embodiments of the nozzle
3 and of the cap 4 which are fully equivalent to one another.
[0027] The use of the bottle according to the invention is as follows: when inactive, the
cap 4 adheres perfectly to the nozzle 3, preventing any possible external contamination
and any possible outflow of liquid contained in the bottle 1.
[0028] During use, by applying an adapted pressure to the bellows-like part S, the end portion
8 of the cap 4 lifts off the nozzle 3 so as to allow the liquid to seep from at least
one aperture 5 to the dispensing port 6.
[0029] Once the pressure of the bellows-like part S has ceased, the portion 8 of the cap
rests again in close contact with the nozzle 3, thus closing the apertures 5 for the
outflow of the liquid and simultaneously preventing the inflow of external contaminants.
[0030] The invention thus conceived is susceptible of numerous modifications and variations
all of which are within the scope of the appended claims.
[0031] In practice, the materials used, as well as the shapes and the dimensions, may be
any within the scope of the protection of the appended claims.
[0032] Where technical features mentioned in any claim are followed by reference signs,
those reference signs have been included for the whole purpose of increasing the intelligibility
of the claims and accordingly, such reference signs do not have any limiting effect
on the interpretation of each element identified by way of example by such reference
signs.
