Description

Bedding manufacturing method using cube-shaped memory foam and cotton and mattress manufactured thereby {The method for manufacturing bedding using memory foam with cotton and the mattress by using its}

The present invention relates to a method of manufacturing bedding using cube-shaped memory foam and cotton, and a mattress manufactured thereby. To be described in more detail, cotton or memory foam is used as an filling material when making cushions, toppers, or mattresses used in bedding. One of the two materials is selectively used, but the pros and cons of both materials are clear, and a bedding manufacturing method using cube-shaped memory foam and cotton was developed to provide bedding that is lighter than general memory foam and can provide a soft feel like cotton, and a method for manufacturing bedding using cube-shaped memory foam and cotton. This relates to mattresses manufactured by

In general, bedding includes various types of blankets, blankets, and cushions, as well as mattresses and toppers placed on top of them. Except for blankets and some types of comforters, fillers are usually placed inside fabric to provide cushioning or keep warm. There are many types available.

Among them, in the past, most mattresses were used in beds and had multiple springs built in to provide a cushioning feeling, but the use of memory foam, which has a relatively thin thickness and was intended to be used on top of a mattress or just on the floor, is also increasing. there is.

Mirrored memory foam is a type of sponge that refers to a foam material that returns to its original distorted shape when physical force is removed. It usually has a low density of 20 to 40 kg, a medium density of 40 to 60 kg, depending on the weight (kg) per ㎥. It is classified as having a high density of 60 to 80 kg, so it can be said to be quite heavy compared to regular sponges.

In other words, when manufactured in a single size with a thickness of about 10 cm, the low density has the disadvantage of having a significant weight of at least 4 kg and the high density has a maximum weight of 16 kg. Although it has excellent resilience, it is inferior to cotton-filled bedding such as traditional blankets or cushions. If you do this, the soft comfort and warmth will decrease.

Therefore, if bedding is lighter than memory foam, has excellent resilience, and provides soft comfort, it is expected to be in great demand.

Republic of Korea Patent Registration No. 10-1851617-0000 (April 18, 2018) Republic of Korea Patent Registration No. 10-2052267-0000 (November 28, 2019) Republic of Korea Patent Registration No. 10-2223111-0000 (February 25, 2021)

The present invention was developed to solve the above-mentioned problems, and its purpose is to solve the disadvantages of memory foam, which has excellent resilience but is heavy, and to provide cube-shaped memory foam and cotton that have excellent resilience but are relatively light and provide a soft feel. The goal is to develop a bedding manufacturing method using .

In addition, the goal is to develop a mattress using cube-shaped memory foam and cotton that can be applied to a mattress and have excellent resilience without being excessively contracted by the user's weight, while also providing soft comfort and warmth like cotton.

In order to achieve the above object, the present invention passes low-density or medium-density mattress foam through cutting parts connected in parallel at regular intervals to form a plurality of thin plates, lays them down again, passes them through them to form a long bar shape, and rotates them 90 degrees to form a plurality of thin plates. A cube-shaped memory foam manufacturing step of manufacturing a plurality of cube-shaped memory foams by allowing them to pass through;

A cotton preparation step of enriching the cotton by spraying air while passing the prepared cotton through a cotton press equipped with a plurality of needles;

A mixing step of adding the cube-shaped memory foam and cotton that have undergone the cube-shaped memory foam manufacturing step and the cotton preparation step at a weight ratio of 1:1 and mixing them in an even ratio by an internal rotating body;

It is characterized by comprising a series of steps of filling the cover or inner cover of the manufactured bedding with the filler provided in the mixing step through a long hose-shaped inlet with high pressure air.

In addition, in the cube-shaped memory foam manufacturing step, the cut portions are formed at intervals of 10 to 50 mm to form a cube-shaped memory foam with one side having a length of 10 to 50 mm.

Additionally, in a mattress including a cover filled with memory foam inside;

The memory foam is characterized by being composed of a plurality of cube-shaped memory foams with a length of 10 to 50 mm on one side and a filler made by mixing cotton that has been twisted at a weight ratio of 1:1.

In addition, the memory foam has a flat plate shape with a thickness of 10 to 30 mm at the bottom, and a plurality of support protrusions that protrude in a cone shape with a bottom diameter of 50 mm or more and are rounded at the top are integrally formed on the upper surface. A lower memory foam is additionally formed in which the spacing between adjacent support protrusions is formed differently depending on the position to respond to the load of each part of the human body on which it is seated;

The filler is characterized in that it fills the space between the supporting protrusions and the upper portion.

In addition, the memory foam is characterized in that a non-woven sheet is additionally formed on top of the filler.

As described above, the present invention cuts the memory foam into the shape of a cube, that is, a hexahedron, and evenly mixes it with cotton of the same weight to fill the inside of the bedding, thereby providing the characteristics of the memory foam with excellent resilience and good thermal insulation and a soft feel. It has the effect of providing bedding with the characteristics of cotton.

In addition, the lower memory foam, which is formed with a plurality of cone-shaped support protrusions with rounded ends, prevents excessive shrinkage under load, and the space between the support protrusions and the upper part is filled with a mixture of cube-shaped memory foam and cotton to provide warmth and insulation. It has the effect of providing a more comfortable mattress by providing a softer feel.

Accordingly, the configuration of the present invention will be described in detail with the accompanying drawings so that those skilled in the art can easily understand and reproduce it.

Figure 1 is a block diagram according to an embodiment of the present invention, in which low-density or medium-density mattress foam is made into a plurality of thin plates by passing through cuts connected in parallel at regular intervals, and then laid down again and passed through to form a long bar shape, A cube-shaped memory foam manufacturing step (100) of manufacturing a plurality of cube-shaped memory foams by rotating them 90 degrees and passing them through;

A cotton preparation step (200) of enriching the cotton by spraying air while passing the prepared cotton through a cotton press equipped with a plurality of needles;

A mixing step ( 300) and;

A cube-shaped product comprising a series of steps of filling the cover or inner cover of the manufactured bedding with the filler provided in the mixing step (300) through a long hose-shaped inlet with high-pressure air (400). A method of manufacturing bedding using memory foam and cotton is shown.

We believe that memory foam has the advantage of excellent resilience, but has the disadvantage of being quite heavy. Cotton has the advantage of providing warmth and a unique fluffy feel and is light in weight, but has resilience, but has the disadvantage of shrinking with repeated use. The purpose is to solve the shortcomings by combining the two.

That is, when mixed evenly in the mixing step (300), the space between the cube-shaped memory foam is filled with cotton. Even if it is a simple mixing, when it is restored after shrinking due to weight, the memory foam is restored by its properties. The cotton in between is forced to expand due to the restoring force of the memory foam.

In other words, the disadvantage of cotton, which is the phenomenon of flattening as its resilience decreases due to repeated use, is eliminated by mixing it with memory foam, and the mixed cotton makes it lighter in weight compared to memory foam of the same volume, giving a softer feel. It will exist.

This structure can be applied to quilted blankets, and during the quilting process, it is fixed to the cube-shaped memory foam by the seam line, preventing the filled filling from moving and being pushed to one side.

At this time, in the cube-shaped memory foam manufacturing step (100), it is preferable that the cut portions are formed at intervals of 10 to 50 mm to form cube-shaped memory foam with one side having a length of 10 to 50 mm. When used for a blanket, topper, or cushion, It is desirable to form it relatively small, and when applied to a macrolith, it is desirable to form it relatively large.

It can also be put directly into the bedding cover, but it can also be manufactured by putting filler in a separate inner cover and putting a cover on top.

Figure 2 is a perspective view according to one embodiment of the present invention, and Figure 3 is a perspective view showing a lower memory foam according to another embodiment of the present invention. Figure 4 is a cross-sectional view according to another embodiment of the present invention, in the mattress 1 including a cover 12 filled with memory foam 11 therein;

The memory foam 11 is a cube-shaped memory foam, characterized in that it is composed of a plurality of cube-shaped memory foams with a side of 10 to 50 mm in length and a filler 111 made by mixing cotton that has been twisted at a weight ratio of 1:1. and a mattress using cotton were shown.

The memory foam 11 can be said to be a type of sponge, but compared to commonly known sponges, it is denser, heavier in weight, and has less shrinkage due to pressure, so it is easiest to apply to a mattress rather than a thin blanket. can do.

Herein, the memory foam 11 has a flat plate shape with a thickness of 10 to 30 mm at the bottom, and a plurality of support protrusions 131 that protrude in a cone shape with a bottom diameter of 50 mm or more and are rounded at the top are integrally formed on the upper surface, The support protrusions 131 are additionally formed with a lower memory foam 13 whose distance from the adjacent support protrusions 131 is formed differently depending on the position to correspond to the load of each part of the human body that is seated when sleeping;

An embodiment was additionally presented wherein the filler 111 is filled in the space between the support protrusions 131 and the upper portion.

At this time, it is preferable that the lower memory foam 13 is manufactured with high density with a small amount of shrinkage due to load. This structure is intended to prevent the user from feeling uncomfortable when excessively contracted due to weight, and has an appropriate amount of shrinkage. This structure was proposed to provide thermal insulation.

At this time, even if there is a cover 12, the user may feel uncomfortable if he or she feels a different tactile sensation and shrinkage due to the cube-shaped memory foam and cotton, so the memory foam 11 is placed on the top of the filler 111 and is a non-woven sheet 14. ) is preferably additionally formed.
