Description
The present invention relates to a method of
manufacturing moulded containers,
which bring substantial features of novelty and inventive
activity to the object for which they are intended.
The moulded containers to which the present
invention relates generally comprise two bodies, a moulded
casing and moulded lid, respectively, produced from
synthetic materials, which are hinged to one another,
generally with moulded elements formed for the said
purpose in the mentioned casing and lid and optionally
with the cooperation of detachable elements, the said
casing and lid comprising, in the closure area, devices
for maintaining the two elements joined to one another in
a releasable manner. Containers of this type are widely
used in various industrial fields, preferably as tool-carrying
containers, containers for small industrial
apparatuses, etc.
In the containers of the type mentioned,
information-carrying sheet-form elements are normally
provided in the form of labels and the like and are
connected to some of the surfaces of the container in
order to indicate, where appropriate, the type and make of
the contents of the container or other information
necessary for the contents of the container or for its
function.
The attachment of the said labels or the like by
means of adhesives nevertheless has certain disadvantages
from the point of view of the difficulty of changing the
information labels or sheets, owing to the labour required
to attach the labels by means of an adhesive and the
ecological disadvantages resulting from the use of
adhesives, etc.
The mentioned disadvantages are more
considerable bearing in mind that many of the containers
of the type for which the present invention is intended
are used to receive different types of contents, as a
result of which, starting from a single container, it is
necessary to change the instruction label or sheet
frequently in order to adapt the container to different
contents.
DE-A-3 121 084 refers to a rectangular container which
has four lateral walls and a bottom wall, having in the lateral
surfaces of the longer sides recesses having slits to receive
corresponding expansions of a web-like element carrying graphic
information. However, said reference does not disclose closable
containers made out of two articulated parts with thickened
portions in the recesses to receive coplanar cuts parallel to the
base of the recess.
The improvements forming the subject- matter of
the present invention are intended to overcome the
mentioned disadvantages by providing means such that it is
possible to arrange the instruction label or sheet in a
very simple manner in containers of the moulded type
without having to use adhesives or the like and with the
possibility of changing the instruction label or sheet
very rapidly and easily.
Basically, the method of manufacturing moulded
containers of the present invention resides in the provision of
recessed areas in those faces of the container which are
to be provided with the instruction labels or sheets, such
as, principally, the larger faces of the container, which
recessed areas may be of varying size and shape and the
depth of which recessed areas is substantially equal to
the thickness of the card or sheet-form element acting as
label, advertisement, instruction carrier, etc., there
being produced in the moulding operation a series of
thickened areas in the form of local ribs which may extend
to the corner areas, intermediate areas, etc., and the
thickness of which may be substantially equal to the depth
of the recess. In a subsequent phase, cuts are made in
the mentioned thickened areas or ribs in a single plane
parallel to the plane of the base of each recess, which
enables the edges of the sheet-form elements to be
introduced into the slots made in the mentioned ribs,
thereby providing for a rapid and easy retention of the
sheet-form element in the container. As will be
appreciated, owing to the application of the present
improvements, the inscription-carrying sheet-form elements
acting as labels, instructions, etc., can be readily
mounted and dismounted from the moulded container, which,
moreover, does not require substantial changes to the
design or moulding in order to obtain the structure
necessary for receiving the sheet-form information
elements.
The operation of cutting the mentioned slots in
the thickened portions or ribs in the areas of the edges
of the recesses mentioned may be effected in a completely
mechanised manner by means of a knife or saw of the
discoidal type, the thickness of which is equal to the
desired width of the slots for introducing the sheet-form
element carrying the printed motifs and which operates in
the manner of a rotating tool having an axis perpendicular
to the base of the recess in which the thickened portions
or ribs have been moulded and which is displaced
automatically for successive following of the various
thickened portions or ribs in such a manner that each of
the containers can simply be centred in a completely
mechanised manner in the work table of a machine having a
structure similar to a vertical milling machine, the
automatic cutting cycle being effected continuously.
For a better understanding of the present
invention, some explanatory drawings of the method
to which the present invention relates are appended by way
of example.
The present invention can be applied to
moulded containers, such as that indicated by the general
reference numeral 1 in Figures 1 and 2, the preferred form
of which is a flat parallelepiped with rounded edges and
which has two irregular halves 2 and 3 which constitute
the casing and the lid, respectively, of the container,
and an upper handle 4 and lower hinges for the
articulation of the two parts 2 and 3 to one another,
lower protuberances such as 5 and 6 being provided as
protuberances for supporting the container.
The present invention provide for the
production, in the moulding phase of the parts 2 and 3, of
recesses 7 which are of a variable size and which
preferably have a shape corresponding to that of the
inscription-carrying sheet-form element which is to be
incorporated in the container, and the depth of which
recesses is very shallow, as shown in Figures 4 and 5
which indicate the flat base of the recess 7 which,
characteristically, has a series of thickened portions or
ribs distributed over its sides and corners, such as the
thickened portions 8, 8', 8'' and 8''' which are in the
form of a right-angle and are arranged in the corners of
the recess and other short, straight thickened portions,
such as those indicated by the reference numerals 9 and 9'
for one of the larger sides and 9'' and 9''' for the other
side. As will be appreciated, the number and arrangement
of the said thickened portions may vary widely and will
depend on the nature of the sheet-form element which is to
be connected to the moulded container. Thus, the exact
shape of the recess may vary within wide limits, depending
on the shape of the sheet-form element carrying the
graphic information, and may be rectangular, as in the
case illustrated, square, pentagonal, circular, etc.
The thickened portions or ribs mentioned above
are to receive coplanar slots which are parallel to the
flat base of the recess 7 and which are preferably
produced by means of a circular tool 10, Figure 6, in the
form of a discoidal saw or mill which rotates about an
axis 11 perpendicular to the plane of the recess 7 and the
thickness of which coincides with that of the slots which
are to be formed in the said ribs. The penetration of the
cutting discs 10 depends on the size of the mentioned ribs
or thickened portions, and the path to be followed by the
discoidal cutting tool is determined by the profile of the
recess 7. In any case, the discoidal cutting tool is
driven automatically, as a result of which the cutting
operation is completely automated.
As shown in Figures 7 and 8, the slots 12 are
produced adjacent to the base 7 of the recesses so that
the sheet-form elements carrying the printed motifs can
fit against the flat base 7.
As shown in Figures 9, 10 and 11, the sheet-form
element 13 carrying various printed motifs 14 has a shape
which substantially matches that of the periphery of the
recesses 7 and has dimensions which enable it to be
introduced into the slots produced by cutting in the
thickened portions. In this manner, the sheet-form element
13 is centered and held well in the desired faces of the
container and can be readily fitted and exchanged in
accordance with the descriptions they are to carry.
The depth of the coplanar cuts is greater than
the width of the thickened portions, thus permitting the
insertion of the sheet-form element which carries the
graphic information and which is completely adapted to the
straight side edges of the recesses.
