Abstract
The invention is a process for making cores (100) of visors (1) of caps (10), wherein the core (100) is obtained through injection moulding of a material comprising at least one part constituted by a biopolymer of plant origin and more preferably by a derivative of corn.
Description
PROCESS FOR MAKING CORES OF CAP VISORS, VISOR CORE OBTAINED THEREWITH AND CAP WITH VISOR PROVIDED WITH A CORE OBTAINED
FROM SAID PROCESS
DESCRIPTION
The present patent concerns caps with visors and in particular it concerns a new process for making cores of cap visors, a visor core obtained therewith and a cap with visor provided with a core obtained from said process.
Caps with visor are known, for example the common baseball caps comprising a domeshaped fabric portion on one edge of which an essentially crescent-shaped visor is attached. The visor in turn comprises a stiffening core, normally but not necessarily finished with a covering material, for example fabric or leather or another material.
Said visor cores of the known type are currently made by cutting a sheet of plastic material. The shape of the core is, for example, that of a portion of an annulus or a sector of a circle. The core is subsequently deformed in order to obtain the most suitable curvature according to the shape of the cap to which the visor must be applied, and finished with a sheet of covering material which, for example, is sewn or glued to the core.
The sheets or plates from which the cores are obtained are usually made by extrusion using thermoplastic resins of synthetic origin.
The drawbacks resulting from the currently used processes and materials are numerous. First of all, the process of die-cutting a sheet always inevitably produces scraps that cannot be recovered for other purposes.
Die-cutting also creates sharp edges, with flash and burrs that require subsequent finishing operations to be performed manually, which reduces the hourly production rate.
Deformation after die-cutting is also a time-consuming process which further reduces the hourly production rate, and it is also a process with a high degree of uncertainty, which therefore does not always guarantee that the desired result will be achieved.
For these reasons, not all of the cores that are eventually obtained are identical.
Furthermore, the material used is a plastic material, which is neither reusable nor
environmentally friendly.
In order to overcome all of the above-mentioned drawbacks, a new process for making cores of cap visors, a visor core obtained therewith and a cap with visor provided with a core obtained from said process have been designed and carried out.
The main object of the present invention is to provide a process that makes it possible to increase the hourly rate of production of cores for cap visors, reducing the time required for any shaping and finishing operations.
Another important object of the present invention is to provide a process that makes it possible to reduce processing waste while at the same time using an environmentally friendly material.
Another important object of the present invention is to provide a process that makes it possible to produce cores, and thus visors, having a predefined and always perfectly replicable curvature.
The new process for making cores of cap visors comprises the following steps: preparation of a mixture of inj ection moulding material; in its preferred form, said material comprises at least one part, and preferably 65%, made up of a biopolymer of plant origin, and more precisely of a derivative of com, and at least one expansion agent; said expansion agent serves the function of creating air microcells within the structure in order to make the core of the visor more workable during application of the covering material; injection of said material into a mould configured to produce a core in a predefined shape and size; extraction of the product; possible reintroduction of processing scraps in the moulding cycle.
The injection moulding process thus produces an exact shape, with the desired curvature and no sharp edges, without requiring any further finishing or bending operations.
One of the advantages deriving from the application of the new process lies in that it reduces the production of scrap, as processing scrap can be fed back into the moulding cycle.
A further advantage comes from the type of material used, which is environmentally friendly as part of the same is derived from com starch.
In addition to the above, the expansion agent contained within the compound makes the material ductile as required and the core more suitable for the stitching of the covering sheet.
The visor core is thus obtained by injection moulding and is made of a material comprising a biopolymer of plant origin, and more preferably 65% of the visor core is made of said biopolymer of plant origin.
The resulting cap thus includes a visor in turn provided with at least one core manufactured as described above, possibly with one or more covering layers sewn or glued or otherwise bonded to said core.
The characteristics of the present invention are better illustrated in the attached figures, which are provided by way of non-limiting example.
A typical example of a cap (10) with visor (1) is shown in Figure 1, where the cap (10) comprises a dome-shaped portion (2) intended to be placed on the user's head, and a visor (1) constituted by a core (100) that is made of a plastic material and can be provided with a covering material.
Figure 2 shows a three-dimensional view of an embodiment of a core (100) for visors (1) of caps (10) which is the subject of the present patent.
The core (1) is obtained by injection moulding and therefore when it leaves the mould it already has the correct shape and curvature. The drawing shows the three dimensions, meaning width (Ly), length (Lx) and height (Lz).
Figures 3 and 4 respectively show a sectional view of the core (100) along plane B-B shown in Figure 2, where the curvature is clearly visible, and a plan view of the core (100).
Thanks to the new process, it is possible to produce cores (100) with generally predefined curvatures and shapes that can be perfectly reproduced an indefinite number of times.
Therefore, with reference to the above description and the enclosed drawings, the following claims are made.
