Field of the invention
[0001] The present invention refers to a packaging for a liquid product equipped with a
straw which allows a consumer to consume in an easy and hygiene-saving manner the
liquid product filling the packaging.
State of the art
[0002] Packaging for liquid products in the form of a container in metal, cardboard and
plastics material of various shapes and with hermetic sealing are widely diffused.
[0003] The consumer which wishes to consume the product (a drink or another liquid product)
opens the packaging by pulling up a tab or by puncturing the side of the packaging
itself and by inserting a straw, if any, so as to allow the product to be consumed
in a more practical manner.
[0004] In both cases, the problem of respecting hygiene standards for safeguarding the health
of the consumer is particularly evident.
[0005] In fact, in the case of cans for drinks, there can be an accumulation of dirt around
the rim of the lid and/or on the opening tab, which clearly involves not negligible
risks of contamination for the product and also, when no straw is used, for the consumer
whose lips come into direct contact with the rim of the can.
[0006] Likewise, a lack of sufficient hygiene conditions is also a not negligible problem
when containers or cans made of plastics material are used, where the part to be punctured
in order to access the drink is composed of a foil cover.
[0007] The already known packaging called "brick packs" are made of a container in cardboard
provided with a pliable point in its upper part which is punctured by the consumer,
which then introduces a straw which is found separately or glued to a side of the
container.
[0008] Even this type of packaging, however, does not ensure complete hygiene as the consumer
must nevertheless handle the straw in order to separate it from the packaging, to
remove it from its wrapping and to insert it in the container.
[0009] Furthermore, the insertion of the straw in the container involves some risks of contaminating
the straw end which, when the pliable point is punctured, draws traces of dirt, if
any, present in the punctured area inside the container and, consequently, also contaminates
the product into which the straw has been inserted.
[0010] A packaging according to the present invention is suitable to overcome the above
mentioned drawbacks as it fully respects the hygiene standards for safeguarding the
health of the consumer and, at the same time, it is economical and simple to use.
Summary of the invention
[0011] The present invention refers to a packaging for liquid products equipped with a straw,
comprising a container and a cover hermetically connected each other, where the straw
is incorporated within the packaging and is isolated by the cover from the external
environment; the lower end of the straw is always immersed in the liquid product filling
the container.
[0012] When the consumer lifts up a tab belonging to the cover, the upper end of the straw
protrudes automatically from the packaging due to the straw flexibility, thus enabling
the liquid product to be consumed in a practical and hygiene-saving manner.

Detailed description
[0014] The present invention refers to a packaging for liquid products equipped with a straw,
comprising a container and a cover hermetically connected each other, where the straw
is incorporated within the packaging and is insulated by the cover from the external
environment; the lower end of the straw is always immersed in the liquid product filling
the container.
[0015] The container and the straw are produced at the same time in a manner not disclosed
therein as it is known to any person skilled in the art, the container constituting
a single unit with the straw.
[0016] at the same time as the straw, so as to constitute a single unit with the packaging.
The upper end of the straw, i.e. the end of the straw used by the consumer to consume
the product, is positioned in a groove realised in the upper edge of the container
and at least partially closed by a tab, belonging to the cover, to be lifted up from
the groove to allow the upper end of the straw to protrude from the packaging.
[0017] Figure 1 shows a perspective view of a first embodiment of a packaging 1 according
to the present invention, comprising the container 3, the cover 4 and the straw 5;
the lower end 6 of the straw 5 is so positioned into the container 3 to be always
immersed in the liquid product (not shown in the enclosed figures to simplify the
graphical representation) which fills the container 3.
[0018] According to the embodiment shown by figure 1, the packaging 1 has a substantially
parallelepiped shape and the straw 5 is positioned into a "L"-shaped groove realised
in the upper edge 2 of the container 3.
[0019] The upper end 8 of the straw 5 is positioned in a first portion 10 of the "L"-shaped
groove, realised in a transversal side 7 of the upper edge 2 of the container 3 and
closed by the tab 9 belonging to the cover 4; the lower end 6 of the straw 5 is positioned
in a second portion of the "L"-shaped groove, provided in a longitudinal side of the
upper edge 2 of the container 3 and so inclined that the lower end 6 of the straw
5, protruding from the second portion of the "L"-shaped groove, remains always immersed
in the liquid product.
[0020] The first portion 10 of the "L"-shaped groove is orthogonal to the second one.
[0021] The first portion 10 of the "L"-shaped groove wherein the upper end 8 of the straw
5 is positioned is shown in figure 2 and (by a dashed line) in figure 4, while in
figures 1, 3 and 5 it is covered by the upper portion 8 of the straw 5; the second
portion of the "L"-shaped groove wherein the lower end 6 of the straw 5 is positioned
is shown in figure 3 and (by a dashed line) in figure 5, while in figures 1, 2 and
4 it is covered by the lower portion 6 of the straw 5.
[0022] According to the preferred embodiment shown in figure 2, once the tab 9 has been
lifted up the upper end 8 of the straw 5 protrudes from the first portion 10 of the
"L"-shaped groove automatically due to the flexibility of the expandable part 11 of
the straw 5, thus enabling the liquid product to be consumed in a practical and hygiene-saving
manner but, without departing from the scope of the invention, the upper end 8 of
the straw 5 can be extracted from the first portion 10 of the "L"-shaped groove manually:
said manual extraction involves risks of contamination as set forth above.
[0023] The automatic protrusion of the upper end 8 of the straw 5 is achieved by fixing
in a known manner the straw 5 in the "L"-shaped groove with its upper end 8 protruding
from the lateral side 7 of the upper edge 2 of the container 3 as shown in figure
2 and by forcing the upper end 8 of the straw 5 into the first portion 10 of the "L"-shaped
groove: the upper end 8 of the straw 5 is therefore lightly pre-loaded by the elastic
contrasting action exerted by the expandable part 11 of the straw 5.
[0024] Preferably the tab 9, once lifted up for opening the packaging 1, cannot be removed
from the packaging 1.
[0025] Figures 3, 4 and 5 show , respectively, the packaging of figure 1 sectioned according
to planes III-III, IV-IV and V-V of figure 1; said figures clearly show the straw
5 positioned into the "L"-shaped groove realised in the upper edge 2 of the container
3 and the lower end 6 of the straw 5 protruding from the "L"-shaped groove inside
the container 3 so as to be always immersed in the liquid filling the container 3.
[0026] Finally, figures 1 to 5 show that at least a lateral side of the substantially parallelepiped-shaped
container 3 provides for one or more hollow or indentations 12 for achieving a more
ergonomic hold of the packaging 1 by the consumer when the liquid product is being
consumed but said one or more hollows or indentations 12 can be omitted without departing
from the scope of the invention.
[0027] Figures 6 to 8 show a second embodiment of a packaging 1, comprising the cylindrical-shaped
container 13 and the cover 16 hermetically connected each other; the upper end 15
of the straw 14 is positioned in a groove 18 realised in the cover 16 of the packaging
1, while the lower end of the straw 14 is positioned inside the cylindrical container
13 and remains always immersed in the liquid, not shown to simplify the graphical
representation.
[0028] Similarly to the cover 4 belonging to the first embodiment of the invention disclosed
above, the cover 16 provides for a tab 17, which covers in a hermetic manner the groove
18 wherein the upper end 15 of the straw 14 is positioned, so as to protect it from
the external environment (figure 6).
[0029] According to the preferred embodiment shown in figures 7 and 8, once the tab 17 has
been lifted up the upper end 15 of the straw 14 protrudes from the groove 18 automatically
due to the flexibility of the expandable part 19 of the straw 14, thus enabling the
liquid product to be consumed in a practical and hygiene-saving manner but, without
departing from the scope of the invention, the upper end 15 of the straw 14 can be
extracted from the groove 18 manually, said manual extraction involving risks of possible
contamination as set forth above.
[0030] Preferably the tab 17, once lifted up for opening the packaging 1, cannot be removed
from the packaging 1.
[0031] Furthermore, the container 13 is produced (in a manner not disclosed therein as it
is known to any person skilled in the art) at the same time as the straw 14, the straw
14 and the container 13 being united each other as to constitute a single unit.
[0032] Finally, according to a further embodiment not shown in the figures, the lower end
of the straw (5, 14) is composed of a channel made directly on a side of the container
(3, 13) by a forming process.

a straw as suggested by the normal experience and by the natural evolution of the
technique may be effected by a skilled person without departing from the scope of
