Detailed description of preferred embodiments of the invention
The numeral 1 in Figures 1, 2, 4, 5 and 6 indicates a possible example
embodiment of a package according to this description. The term
"package" is used below to mean the possible example embodiment.
The package 1 is configured to allow a user to apply a product, using the
package 1, initially contained in the package, on an application surface on
which the user wishes to apply the product. The package 1 is in particular
designed to allow and/or facilitate the application where the application
requires a pressure or friction between an element for applying the product
and the application surface. The element for applying the product, in the
package 1, is an absorbent element 52, in which the product is absorbed.
The absorbent element 52 is represented very schematically in Figures 1,
2, 3, 6, 8 and 9.
The package 1 comprises a semi-rigid structural sheet 2.
The package comprises an opening system. The opening system

comprises a weakness 3. An opening system is configured so that the
weakness 3 allows a user to cause a movement of said package 1 from a
closed condition to an open condition. The weakness 3 is also configured
for guiding the movement of the package 1 from the closed condition to
the open condition.
The weakness 3 comprises a line of weakness. The line of weakness is
configured in such a way that the movement of the package 1 occurs
around the line of weakness. The line of weakness is situated on the
structural sheet 2. The line of weakness is made by microscopic incision
and/or flattening of the material of the structural sheet 2.
The line of weakness defines, on the structural sheet 2, a tab 6.
The package comprises a flexible covering sheet 4. The flexible covering
sheet 4 is fixed on the structural sheet 2 in such a way as to form a space
V. The space V is interposed between the structural layers 2 and the
covering sheet 4. The space V, in the closed condition of the package, is
closed. The space V is visible in cross-section in Figure 3.
The line of weakness divides the structural sheet 2 into a first area 21 and
a second area 22. The first area 21 and second area 22 are shown in
Figures 4 and 5. The second area 22 is also indicated in Figure 6. Figure 4
shows the package 1 from below and therefore seen from the side of the
face of the structural sheet 2 facing the opposite side relative to the space
or covering sheet. In Figure 4, as in Figures 1 to 3, the package 1 is in the
closed condition. Figure 5 shows the package 1 in an intermediate
condition between the closed condition and the open condition, for
example during the movement from the closed condition to the open
condition. Figure 6 shows the package 1 in the open condition.
The first area 21 comprises a main portion 211 and the tab 6. The tab 6
therefore belongs to the first area 21 of the structural sheet 2 or is
situated
on the first area 21 of the structural sheet 2.
The tab 6, in the closed condition of the package 1, protrudes from the first
area 21 towards the second area 22.

The package comprises a system for applying the product. The application
system is configured to allow a user to perform the above-mentioned
application when the package 1 adopts the open condition and by means
of the package 1 itself. The application system, in the closed condition of
the package 1, is situated in the space V.
The application system comprises an applicator 5. The applicator is
indicated with a dashed line in Figures 1 and 2, since it is covered by the
covering sheet 4. Figure 9 shows the isolated applicator 5. Figures 3 and 8
show the applicator 5 according to cross-section III-Ill of Figure 2. The
applicator 5 is indicated in Figure 6. The applicator 5, at least in the
closed
condition, keeps the product in position in the space V. The applicator 5
also keeps the product in position in the open condition of the package 1
and during the movement of the package 1 from the closed condition to
the open condition.
The application system and the opening system are configured in such a
way that, in the open condition, at least a part of the applicator 5 protrudes
outside said space V. The applicator 5 protrudes from the space V, in the
open condition of the package 1, in such a way as to allow a user to apply
said product by moving said at least a part of said applicator 5 in contact
with the above-mentioned application surface.
The package 1 can be easily handled by the user for applying the product.
The product could be, for example, a solid-type lipstick.
The at least a part of the applicator 5 comprises at least the application
element or absorbent element 52.
The at least a part of the applicator 5 is situated, in the closed condition
of
the package 1, on the tab 6. In that way, when the package 1 is in the
open condition, the at least a part of the applicator 5 is positioned in such
a way as to facilitate the above-mentioned application of the product by
the user, who is easily able, manoeuvring the at least a part of the
applicator 5 directly or through the tab 6, to apply the product generating a
suitable movement of the at least a part of the applicator 5 in contact with
CA 03122734 2021-06-09
WO 2020/157625
PCT/IB2020/050600
the application surface and/or simultaneously suitably pressing the at least
a part of the applicator 5 on the application surface.
The applicator 5 comprises a support 51 and the absorbent element 52.
The support 51 supports the absorbent element 52. The absorbent
5 element 52 is fixed to the support 51. The application system and opening
system are configured so that the closed condition of the package 1
corresponds to a first position of said absorbent element 52 relative to said
space V. In the first position of said absorbent element 52 relative to said
space V, for example as shown in Figures 1 to 3 and 8, the absorbent
element 52 is situated inside said space V. In this first position, the
absorbent element is inside the space V, together with the entire
applicator 5.
The application system and opening system are configured so that said
open condition of the package 1 corresponds to a second position of said
absorbent element 52 relative to said space V. In the second position of
said absorbent element 52 relative to the space V, shown in Figure 6, the
absorbent element 52 is outside said space V. Thus, in the open condition
of the package 1, at least the absorbent element 52 is situated outside the
space V.
The application system and the opening system are configured in such a
way that, in the open condition of the package 1, the absorbent element
52 faces directly towards the outside of the package 1.
This facilitates the operation for applying the product by the user, who can
easily manoeuvre the absorbent element 52. With the interposing of the
support 51 and, if necessary, also of the tab 6, the user can manoeuvre
the absorbent element 52, for precisely applying the product in the desired
manner on the application surface.
The absorbent element 52 is fixed and/or positioned on the support 51 in
such a way that, in the open condition of the package 1, a user can rub the
absorbent element 52 on the surface, manoeuvring the support 51, so as
to apply the product on the application surface.

The application system is configured so that the support 51, in the closed
condition of the package 1, extends astride between said tab 6 and said
main portion 211 of the first area 21, in such a way as to define a first
portion 511 and a second portion 512 of the support 51. The first portion
511 and second portion 512 of the support 51 are indicated in Figure 4,
and in Figures 7 to 9.
In this closed condition, the first portion 511 of the support 51 is situated
on the tab 6. The absorbent element 52 is fixed and/or positioned on the
first portion 511 of the support 51. The second portion 512 of the support
51 is situated on the main portion 211 of the first area 21 of the structural
sheet 2.
The opening system and the application system are configured so that
said movement of the package 1 ensures that the tab 6 separates
completely from the second area 22 of the structural sheet 2. Thus, in the
open condition of the package 1, the application or absorbent element 52
remains well uncovered to facilitate application of the product by the user.
In particular, the use of the package 1 for the purposes of applying the
product is facilitated, if the product to be applied is a lipstick, or similar
product, which the user wishes to apply on their lips and which requires,
for its correct application, pressing the application element on the
application surface and at the same time moving it relative to the
application surface.
The line of weakness comprises a first lateral sector 31. The line of
weakness comprises a second lateral sector 32.
The line of weakness comprises a central sector 33. The positioning of the
central sector 33 is in particular visible in Figure 4. The central sector 33
is
interposed between the lateral sectors 31 and 32.
The lateral sectors 31 and 32 delimit said main portion 211 of said first
area 21 of the structural sheet 2. The central sector 33 describes a recess
relative to the lateral sectors 31 and 32, in such a way that the central
sector 33 delimits and defines the tab 6.

In particular, the opening system is configured so that, following said
movement of the package 1, the central sector 33 breaks in such a way as
to separate completely the tab 6 relative to said second area 22 of said
structural sheet 2.
It should be considered that the movement from the closed condition to
the open condition of the package 1 is obtained by the user by imparting to
the structural sheet 2 and covering sheet 3 a moment of rotation about the
line of weakness, which defines the tab 6, on which the support 51 is
positioned, which in turn comprises, as mentioned above, a first portion
511, located on the tab 6, and a second portion 512, positioned on the
main portion 211 of the first area 21 of the structural sheet 2. The
positioning of the first portion 511 and of the second portion 512 of the
support 51 is such that, during the movement of the structural sheet 2 and
the covering sheet 3, following this moment of rotation, the support 51
facilitates the breaking of the central sector 33 of the line of weakness, in
such a way that the tab 6 separates at least partly, and preferably
completely, from the second area 22 of the structural sheet 2. In this way,
the support 51, as well as supporting the application element 52, which in
turn keeps the product in position and allows the application, also performs
the function of facilitating the separation of the tab 6, in such a way as to
optimise, for the purposes of this application, the positioning of the
application element 52 in the open condition of the package 1.
The application system comprises a constraint 53. The support 51 is
connected or fixed to said structural sheet 2, and in particular to the first
area 21 of the structural sheet 2, by means of the constraint 53. The
constraint 53 extends preferably only on a transition zone between said
first portion 511 and second portion 512 of the support 51. In that way, the
end portions of said first portion 511 and second portion 512 are
uncovered. In this way a saving is obtained for the operations for obtaining
the constraint 53 and the function of assisting the breakage of the central
sector 33 is improved, a function which is performed at least partly by the
CA 03122734 2021-06-09
WO 2020/157625
PCT/IB2020/050600
8
support 51. In particular, the constraint 53, if it extends only in the
transition zone between the first portion 511 and the second portion 512,
practically defines a hinge line between the structural sheet 2 and the
support 51, and preferably between the first area 21 of the structural sheet
2 and the support 51. The hinge line is situated along the transition zone
between the tab 6 and the main portion 211 of the first area.
The constraint could be a welding line interposed between the first portion
511 and the second portion 512 and/or between the tab 6 and the main
portion 211 of the first area 21 of the structural sheet 2.
The support 51 and the structural sheet 2 are fixed to one another on
respective faces both made of polypropylene or polyethylene or polyactic
acid. In this way, the operation for obtaining the welding is facilitated.
The package 1 may be used to contain a single dose of product for a
single use of the product, the dose being kept in position by and absorbed
in the absorbent or application element 52. The package 1 is also
configured to allow this use to be performed by means of the package 1
itself, in particular and advantageously if the correct use of the product
requires its application on an application surface by moving the application
element and pressing it on that surface. For example, the product could be
a solid or liquid lipstick.
The single-dose package can be opened with a single hand, and is
configured in such a way as to allow a user to perform the application of a
product on an application surface by using the package. The package is
designed to allow and/or facilitate the application where the application
requires a pressure or friction between an element for applying the product
and the application surface. The element for applying the product is an
absorbent element in which the product is absorbed.
