Introduction
[0001] The present patent application refers to an unprecedented constructive arrangement
applied to mattresses, and is designed to reduce costs and bring significant improvements
to the technological sector of mattresses which, moreover, at the end of its useful
life may be used to form a new perimeter edge by means of recycling.
Field of application
[0002] The innovation now claimed is applied to the technological sector of mattresses.
Technical problem to be solved
[0003] One of the oldest inventions of the world - the mattress - is currently manufactured
with perimeter edges and center made of polyurethane foam, or cluster which is comprised
of leftovers of polyurethane foams pressed and heated to shape the format and resistance
necessary so that said perimeter edge receives the strength applied by the weight
of the user.
[0004] However, the perimeter edges and the center of the conventional mattress are made
of polyurethane and are not recyclable, which generates an environmental problem regarding
the handling of the disposal of the mattresses.
[0005] Another technical drawback of polyurethane foam used in making the perimeter edge
and the center of the mattress is that it comprises open cells, which leaves the mattress
prone to the proliferation of fungi and bacteria. Nevertheless, being comprised of
open cells to acquire resistance and compression, the conventional perimeter edges
have their density increased, which leads to the increase in final weight of the mattress.
State of the art
[0006] The current state of the art anticipates certain patent documents which refer to
the subject matter in question, such as document
BR 102015003989-1 A2, entitled "Spring mattress and process for manufacturing same", which shows a mattress
characterized by two sides (3) and (4), cut or manufactured from expanded polystyrene
(EPS).
[0007] The above document discloses two sides that make up the edge of the mattress, both
comprising a solid format. Therefore, it discloses different sides to the application
now claimed, which proposes an edge endowed with hollow longitudinal cavities.
[0008] Document
BR 102016003200-8 A2, entitled "ARRANGEMENT APPLIED TO DOUBLE-FACE MATTRESS, PROCESS FOR MANUFACTURING
MATTRESS", is comprised of ends made of polyurethane
Polyframe (2).
[0009] The above document discloses two sides that make up the edge of the mattress, both
comprising a solid format made of
Polyframe foam, which differs from the sides of the application now claimed which, as already
mentioned above, is designed to shape a perimeter edge endowed with hollow longitudinal
cavities for greater resistance to compression, as well as a reduction in weight of
the perimeter edge.
Objectives of the innovation
[0010] It is an objective of the present innovation to propose a mattress that comprises
a perimeter edge and its entire center made of polyethylene with closed cellular structure,
which contributes with water impenetrability or a water vapor imperviousness; further,
it is designed to decrease the possibility of propagating fungi and bacteria in the
mattress;
[0011] It is an objective of the present innovation to propose a mattress with a perimeter
edge and its center made of polyethylene having lower density and greater resistance
to compression, compared to polyurethane foams;
[0012] Lastly, it is an objective of the present innovation to propose a mattress with a
perimeter edge and center made of polyethylene, which at the end of its useful life
is recycled for the production a new mattress, upon undergoing recycling.
Summary of the innovation
[0013] A
CONSTRUCTIVE ARRANGEMENT APPLIED TO A MATTRESS presents a structure composed of threads endowed with longitudinal cavities, which
are joined by way of plastic weld with a thermal blower, forming a perimeter edge
for a mattress.
[0014] The innovation is made of polyethylene comprised of pores or closed cells which contributes
with water impenetrability or water vapor imperviousness, as well as decreased possibility
of propagating fungi and bacteria in the mattress. However, it may undergo modifications
in its resistance and weight, and also be used to shape a new perimeter edge for a
mattress at the end of its useful life, by recycling.
Advantages of the innovation
[0015] In short, the main advantages of the perimeter edge are:
- Reduction of weight in the mattresses;
- Reduction of fungi and bacteria in the mattress;
- Recycling;
- Flexibility;
- Resistance to compression;
- Water impenetrability or water vapor imperviousness.

Detailed technical description of the innovation
[0017] The
CONSTRUCTIVE ARRANGEMENT APPLIED TO A MATTRESS refers to a mattress (1) endowed with a center (2) with a perimeter edge (3), composed
of threads (4) endowed with longitudinal cavities (5) which, when welded or glued
to each other, form a center (2) and a perimeter edge (3), capable of reducing costs
and bringing significant improvements to the technological sector of mattresses, and
also of making the center (2) and the perimeter edge (3) recyclable to form a new
mattress (1).
[0018] More particularly, the mattress (1) is composed of a structure (E), which is arranged
by the center (2) and the perimeter edge (3), comprising threads (4) endowed with
longitudinal cavities (5), and the threads (4) are joined by way of glue or plastic
weld (X) with the assistance of a thermal blower, forming an innovated mattress (1).
[0019] It is worth pointing out that the mattress (1) is composed of a center (2) and a
perimeter edge (3) made of polyethylene, comprising pores or closed cells (S) which
contribute with water impenetrability or water vapor imperviousness, and also decreases
the possibility of propagating fungi and bacteria in the mattress (1). Nevertheless,
it may undergo modifications to improve its resistance to compression and weight,
and to be used to shape a new mattress (1) at the end of its useful life, by recycling.
