Description

DESCRIPTION

Stuffing for pillow and pillow comprising said stuffing

field of invention

The present invention relates to the field of pillow manufacturing. In particular, the present invention refers to the manufacture of anatomical pillows that allow improving the quality of the user's sleep.

State of the art

On the market, there are pillows of more or less complex versions that comprise a shaped filling and a covering part, or cushion. In order to improve the quality of sleep, for example, to prevent some cervical and shoulder pathologies, or to improve conditions in users who already suffer from these pathologies, pillows are made with anatomical shapes that try to adapt to the most comfortable sleeping positions. in order to provide the best possible stability of the deep sleep phases, improving the quality of rest.

Known pillows of this type comprise a shaped padding having a lowered central zone comprised between two raised lateral zones in which the lowered central zone facilitates the supine resting position.

The known types of padding are made in a single shaped polyurethane body in which said central zone and said lateral zones are defined.

A first disadvantage of the prior art for the manufacturers of such pillows is the need to produce a wide variety of fillings with various sizes to optimally adapt to the complexions of the end users, or else the user will have to settle for a pillow that suits your complexion.

The production of a wide variety of pillows/stuffings requires the use of corresponding machinery/moulds and the consequent high fixed costs.

Another disadvantage of known pillows is related to their use and position changes during sleep. In fact, during changes of position during sleep, the head alternately rests on these areas depending on the position during sleep of the user, whether supine or lateral. The known types of padding are particularly inconvenient in the event that it is desired to change from the supine to the lateral position. In fact, the movement of the head during the natural rolling movement to the lateral position is prevented or, in any case, it is not facilitated due to the differences in height between the various zones that, in fact, force the head to be raised, with the obvious consequences of a bad rest.

Therefore, the object of the present invention is to solve, or at least partially avoid, the above mentioned disadvantages.

In particular, an objective of the present invention is to propose a solution that allows the manufacturer to offer a wide range of pillows to the consumer, while keeping production costs low.

Another objective is to improve the quality of sleep of the user who uses a pillow shaped according to the invention.

Detailed description of embodiments of the invention

Although the present invention is described below with reference to embodiments thereof shown in the drawings, the present invention is not limited to the embodiments described below and shown in the drawings. On the contrary, the embodiments described below and represented in the drawings clarify some aspects of the present invention, the object of which is defined by the claims.

The present invention applies particularly, although not exclusively, to the field of manufacturing pillows with polyurethane filling.

However, it should be noted that the applications of the present invention are not limited to said type of solution; on the contrary, the present invention finds an advantageous application in the production of a pillow with a filling of any kind, as will become apparent from the present description.

With reference to figures 1 to 6, a first embodiment of a pillow 1 and the corresponding padding 10 according to a first preferred embodiment of the invention is described.

In fact, the pillow 1 comprises a containment shell 4, commonly known as a cushion 4, and a filling 10.

The illustrated and described pillow 1 refers, in particular, to a shaped pillow and also known as an ergonomic pillow.

The cushion 4 is preferably made of textile material, such as, for example, cotton, satin, wool, etc., and preferably comprises an opening side 6 to allow the insertion or removal of the filling 10. The cushion 4 is preferably provided with buttons on the opening side or, in different embodiments, equivalent means, such as Velcro, zipper, etc. The cushion 4 represents the part on which the user's head rests directly.

The padding 10 comprises a core 11 that globally has a central zone 10 defined between a first lateral zone 14 and a second lateral zone 16. The central zone 12 has a height lower than that of the first lateral zone 14 and a height also lower with with respect to that of the second lateral zone 16.

The three zones 12, 14 and 16 previously indicated define corresponding zones where the user's head rests: preferably, the head rests on the central zone 12 when the user sleeps in a supine position, the head rests on the first lateral zone 14 when the The user sleeps on the right side and the head rests on the second side zone 16 when the user sleeps on the left side.

According to one aspect of the present invention, the core 11 of the padding 10 comprises a base body 20 and an insert 40 adapted to be positioned on the base body 20 during rest.

Preferably, the base body 20 comprises a first part 22 that defines the first lateral area 14 of the padding and a second part 24 that defines the second lateral area 16 of the padding 10. An intermediate part 26 preferably connects the first part 22 with the second. part 24 and said intermediate part 26 have a height less than that of the first part 22 and the second part 24. According to another aspect of the present invention, the first part 22, the second part 24 and the intermediate part 26 are made of a single body and the insert 40 is advantageously positioned to rest on the intermediate part 26 of the base body 20.

The base body 20 and the various parts 22, 24 and 26 that make it up are preferably made of polyurethane. The insert 40 is also preferably made of polyurethane. In a preferred embodiment, the base body 20 and/or the insert 40 can preferably be made of shape-memory polyurethane.

According to the configuration described, the height of the first lateral zone 14 of the padding 10 corresponds to the height of the first part 22 of the base body 20, the height of the second lateral zone 16 of the padding 10 corresponds to the height of the second part 24 of the base body 20 and the height of the central zone 12 of the padding 10 corresponds to the height of the intermediate part 26 of the base body 20 added to the height of the insert 40.

Therefore, according to an advantageous aspect of the present invention, it will be possible to obtain a padding with different differences in height between the central zone 12 and the lateral zones 14 and 16 using the same base body 20, used substantially as a standard element, and using an ad hoc insert 40 with the desired height depending on the case.

The manufacture of padding or pillows with different heights can be achieved at lower costs, since the same template/mould can be used for the manufacture of the base body.

In addition, the customer/user can be offered a wide range of pillows with the most appropriate height for their complexion.

Still advantageously, the provision of the insert element 40 in the central zone 12 makes it possible to differentiate the degree of softness, or rigidity, of said zone 12 with respect to the lateral zones 14 and 16.

In fact, these characteristics are mainly conferred by the type of material used, and in particular depend on the density of the material itself, that is, the weight of the material per unit of volume (expressed, for example, in kg per cubic meter).

Thus, advantageously, in a preferred embodiment, the base body 20 is made of a polyurethane that has a density greater than that of the polyurethane with which the insert 40 is made.

This makes it possible to provide a greater degree of softness to the central area 12 with respect to the lateral areas 14 and 16, providing greater comfort for resting the head during sleep in the supine position.

In addition, advantageously, a padding with different height differences between the central area 12 and the lateral areas 14 and 16 allows a correct alignment of the cervical spine, which remains in a physiological position in all sleep positions, thus favoring the maintenance of a correct posture during sleep, with the consequent benefit during the day.

According to a preferred embodiment, the base body 20 is made of a polyurethane with a density between 18 kg/m3 and 50 kg/m3, preferably a density between 21 kg/m3 and 35 kg/m3, more preferably a density of 32 kg/m3.

According to a preferred embodiment, the insert 40 is made of a polyurethane with a density between 16 kg/m3 and 32 kg/m3, preferably a density between 20 kg/m3 and 28 kg/m3, more preferably a density of 25kg/m3.

According to the preferred embodiment shown in the figures, the first part 22 and the second part 24 of the base body 20, and therefore the respective lateral zones 14 and 16 of the padding 10, have a symmetrical shape with respect to the intermediate zone 26 and, more preferably, are the same.

However, in variant embodiments, the first part and the second part of the base body can have different shapes.

With respect to the shape of the various parts of the filling 10 and of the respective core 11, reference is made later herein to the preferred embodiment shown in the figures, in which a first direction X is identified, which extends longitudinally to affect the first lateral zone 14, the central zone 12 and the second lateral zone 16 of the padding 10. A second Y-direction extending perpendicular to the first X-direction is also identified.

As shown in figure 4, preferably, the first side zone 14 has a height that remains constant along the first direction X, the central zone 12 preferably has a height that remains constant along the first. direction X and the second side zone 16 has a height that remains constant along the first direction X.

Advantageously, the lateral zones 14 and 16 of the padding have the same height and adapt correctly to the posture of the user when he sleeps on his right or left side.

As shown alternately in Figures 5 and 6, the heights of the padding 10 along the second direction Y vary. In fact, the height of the padding along said direction Y is preferably adapted to the user's complexion and is preferably higher in the area where the neck or nape rests than in the area where the head rests.

In particular, preferably, the pattern of the filling 10 and its zones 12, 14 and 16 along said second direction Y is of the double wave type.

Figure 5 shows the pattern of the first and second lateral zones 14 and 16, preferably equal to each other, in which the double wave pattern is defined by a central zone of minimum height 14a, 16a comprised between the first lateral zone of height maximum 14b, 16b and the second lateral zone of maximum height 14c, 16c.

According to the preferred embodiment shown in the figures, the first maximum height side zone 14b, 16b and the second maximum height side zone 14c, 16c, 12c have the same height.

Figure 6 shows the pattern of the central zone 12, in which the double wave pattern is defined by a central zone of minimum height 2a comprised between a first lateral zone of maximum height 12b and a second lateral zone of maximum height 12c.

According to the preferred embodiment shown in the figures, the first side area of maximum height 12b and the second side area of maximum height 12c have the same height.

This gives the pillow 1 a preferably symmetrical shape along the second direction Y, and therefore it can be used by the user without worrying about the orientation of the pillow 1.

In a different preferred embodiment, shown, for example, with reference to Figures 7 and 8, the first maximum height lateral zone 14b, 16b and the second maximum height lateral zone 14c, 16c of the first and second lateral zones 14 and 16, present heights different (FIG. 7) and the first maximum-height lateral zone 12b and the second maximum-height lateral zone 12c of the central zone 12 have different heights (FIG. 8).

Therefore, the pillow 1 can be used in a different way depending on its orientation, as shown schematically in figures 9A and 9B, in which the head of the user sleeping in the supine position rests at different heights on the central area 12 depending on how the pillow 1 is oriented. Similarly, as schematically shown in Figures 9C and 9D, in sleep positions on the right side, the user's head rests at different heights on the second lateral area 16 or on the first lateral zone 14, respectively, depending on how the pillow 1 is oriented.

With reference to figures 10 to 13, a variant embodiment of the pillow 101 according to the invention is shown.

Said embodiment differs from the embodiment shown and described with reference to figures 1 to 6 mainly due to the fact that the padding 110 also comprises a polyester covering layer 120 covering the core 11 and a containment envelope 130. which is wrapped around the cover layer 120.

Component parts corresponding or equivalent to the first embodiment are identified by the same reference numerals.

The pillow 101 according to said embodiment, first of all, preferably provides the polyester covering layer 120 which, by enveloping the core 11, provides greater stability to the structure. The core 11 is preferably made according to what has already been indicated above or with the base body 20 and the respective insert 40.

Preferably, the polyester cover layer 120 is made of a plurality of polyester layers that are wrapped around the core 11 to stably contain the base body 20 and the insert 40.

The pillow 101 according to said embodiment preferably further provides the containment envelope 130 which, in turn, encloses the assembly consisting of the core 11 and the cover layer 120.

The containment shell 130 imparts additional stability to the structure and, in particular, maintains the desired adhesion and stability between the included parts, that is, the base body 20, the insert 40 and the cover layer 120.

Preferably, the containment shell 130 is made of a textile material, such as, for example, cotton, and preferably defines a closed structure. Optionally, the containment shell 130 may have an opening side for the insertion of the various parts 20, 40 and 120, said opening side preferably being closed after the insertion of the parts 20, 40 and 120, of way that defines a stable closed structure.

In a preferred embodiment, the pillow may comprise only the polyester cover layer.

Therefore, it has been shown that the padding and the pillow according to the present invention allow to achieve the intended objectives. In particular, the present invention allows the manufacturer to offer a wide range of pillows to the consumer, while keeping production costs low.

Although the present invention has been described with reference to the particular embodiments shown in the figures, it should be noted that the present invention is not limited to the particular embodiments shown and described; on the contrary, additional variations of the indicated embodiments and materials are included within the scope of the present invention, in which said scope is defined by the claims.
