Description of the invention
[0008] A typical package of the present invention comprises an outer sleeve and a tray accommodated
slidably within the outer sleeve and capable of motion between a closed position and
an open position, and the package comprises a locking mechanism for preventing immediate
opening of the package from the closed position to the open position. In a typical
package of the present invention said locking mechanism comprises
- a locking part arranged inside the outer sleeve,
- a first flap arranged to a first end of the tray, and which first flap has bound outside
the side wall of the tray, wherein an end of the first flap is arranged against the
locking part of the outer sleeve, when the package is in closed position, and
- an opening flap arranged to the outer sleeve, and the opening flap and the first flap
are arranged at least partly overlapping when the package is in closed position,
and the tray further comprises a projecting part at a second end of the tray, which
projecting part is folded inside the outer sleeve when package is in closed position.
[0009] A package according to the invention is preferably a carton package. The present
invention is based on a structure of the package comprising two parts: an outer sleeve
and a tray. The outer sleeve is around the tray when the package is in closed position.
A combination of the structural elements arranged to the outer sleeve and the tray
provides child proof locking mechanism for preventing immediate opening of the package
from the closed position to the open position, and an additional security mechanism
for preventing pull out the products from the package when the package is closed.
[0010] A package according to the invention comprises two large planar surfaces, namely
a front surface and a back surface. Further, it comprises a first and a second sidewall,
and a first and a second end wall, which are essentially perpendicular to the upper
surface and to the back surface. The package of the invention is formed from two parts:
an outer sleeve and a tray accommodated slidably within the outer sleeve. The outer
sleeve forms a front surface, a back surface, a first and a second side walls and
one of the end walls of the package, when the package is closed. The end wall formed
by the outer sleeve is a bottom part of the package. Another end wall of the package
is formed by the end of the tray, and it makes possible to open package and slide
the tray out from the outer sleeve. The tray is otherwise inside the outer sleeve
when the package is closed.
[0011] A first end of the tray is the end, which is inside the outer sleeve, i.e. the end
which is the first when tray is slid inside the outer sleeve. A second end of the
tray is the end, which is visible when the package is in closed position. In addition
to the first and the second ends, the tray comprises side walls and a bottom surface.
An upper surface of the tray is open. The item(s) or product(s) to be packed are arranged
on the tray inside the outer sleeve.
[0012] The structural elements relating to the locking mechanism of the package are constructed
both to an outer sleeve and to a tray of the package. The locking mechanism of the
package prevents immediate opening of the package from the closed position to the
open position. The locking mechanism comprises a locking part arranged to the outer
sleeve and positioned inside the outer sleeve, a first flap arranged to a first end
of the tray and an opening flap arranged to the outer sleeve. The first flap of the
tray has bound outside the side wall of the tray, wherein an end of the first flap
is arranged against an end of the locking part of the outer sleeve, when the package
is in closed position, and thus preventing the opening of the package. The opening
flap and the first flap are arranged at least partly overlapping when the package
is in closed position for providing releasing of the locking mechanisms by pushing
the opening flap inside. According to one preferred embodiment of the invention, the
opening flap and the first flap of the tray are substantially fully over-lapped when
the package is in closed position.
[0013] A tray of the package according to the present invention comprises a projecting part
arranged to a second end of the tray for preventing pull out the products from the
package when the package is closed. When the package is in closed position the projecting
part is inside the outer sleeve. In other words, the projecting part is folded inside
the outer sleeve. The projecting part is bound substantially to same plane as the
upper surface of the outer sleeve and thus it forms obstacle to take the products
from the tray, since the upper surface of the tray is open. According to an embodiment
of the invention, the projecting part has cut out from a flap of the second end of
the tray, which flap is folded inside the second end of the tray. This enables a simple
blank structure.
[0014] According to an embodiment of the invention, the first end of the tray comprises
a first flap and a second flap, which are bound outside of the side walls of the tray.
A first and a second flap are arranged to opposite sides of the tray. In an embodiment
of the invention, the first flap and the second flap of the tray are at least partly
attached to the side walls. In an embodiment of the invention, the first flap and
the second flap of the tray are attached, e.g. glued, to the side walls of tray by
substantially whole length of the flaps. One of the flaps is a part of the locking
mechanism as disclosed above. The locking mechanism of the package according to the
invention may be formed in such a manner that it acts correctly irrespective of is
the first flap or the second flap of the tray arranged against the locking part of
the outer sleeve. However, in a preferred embodiment of the invention the first flap
and the second flap have a slightly different shape. In an embodiment of the invention,
a length of the first flap of the tray is arranged to be greater than the length of
the second flap of the tray, wherein the first flap is preferably meant to be a part
of the locking mechanism. The length of the first flap is dependent on the position
of the opening flap in the outer sleeve. In an embodiment of the invention, the first
flap of the tray is dimensioned so that it elongates to a folded line of the opening
flap arranged to the outer sleeve when the package is in closed position.
[0015] In a typical embodiment of the invention, a first flap of the tray and a locking
part of the outer sleeve are arranged in a same line, wherein an end of the first
flap is arranged against the end of the locking part of the outer sleeve, when the
package is in closed position. A locking part of the outer sleeve is typically a flap
folded inside the outer sleeve.
[0016] In an embodiment of the invention, a second flap of the tray is arranged to be connection
with a flap of the outer sleeve arranged at the side wall of the open end of the outer
sleeve, when the package is opened for preventing to draw the tray fully out from
the outer sleeve. This ensures that the tray is always right assembled to the outer
sleeve, because the tray cannot be easily removed wholly inside the outer sleeve.
Therefore, the locking mechanism of the package may be used several times and a function
as a child resistant package is ensured.
[0017] In an embodiment of the invention, the side walls of the tray are two folded by providing
strong side walls and therefore more strongly built tray. The first end of the tray
may be made of a single wall since it is inside the outer sleeve, also in open position.
It also makes a blank for the tray simpler and save material required.
[0018] The package according to the invention is formed from two blanks, a first blank for
the outer sleeve and the second blank for the tray. Manufacturing of the package from
two blanks makes possible it that the package also comprises a mechanism for preventing
to draw the tray fully out from the outer sleeve.
[0019] The outer sleeve of the package according to the invention comprises an opening flap.
An opening flap may have a hinged structure. At least one side of the opening flap
comprises contacting points, the opening flap is connected to the outer sleeve with
connecting points before the package is opened first time. Thus, it is possible to
find out whether or not a package has been previously opened. This only works once
but for certain applications it is useful for security reasons to have this function.
[0020] Typically, the blank for the package according to the present invention is made from
paper board with a weight between 100 g/m
2 and 600 g/m
2. In an embodiment of the invention, the paper board is covered at least on one side
with a coating having a thickness between 5 µm and 150 µm, more preferably between
25 µm and 75 µm. In an embodiment the paper board is covered on both sides.
