Description

Neck pillow for preventing the refrigerant material from slipping and bursting of the sheet adhesive part {a colling neck pillow}

The present invention relates to a neck pillow in which air is injected while using a refrigerant material filling material capable of lowering the user's body temperature in the neck pillow, improving the structure of the neck pillow to prevent the refrigerant material from filling and preventing adhesion of the refrigerant. This is to prevent and control the height of the neck pillow, but to make the heat exchange efficiently.

In general, pillows are used to support the head or support the neck when people sleep, and when the sleeping posture is disturbed because the pillow does not fit the user's body, tension occurs in the sleeper's neck and shoulders, and it is difficult to get a good night's sleep. In addition, long-term use adversely affects health, causing pain such as headaches.

Therefore, recently, a "C" shaped neck pillow that can support the back neck has been proposed, and the user rests his neck by resting his neck and rests the muscles of the back neck and the neck bone maintains a normal curve, resulting in fatigue recovery. Neck pillows, which enable you to sleep in a fast and stable position, are widely used.

However, most of these conventional neck pillows are manufactured by inserting a filling material having an elastic restoring force such as a memory foam to increase the cushioning power. In particular, because the night temperature is high, sweat is easy to get cold in a tropical night, so it is unpleasant and very reluctant to use.

In other words, there is no problem that it is not possible to get a good night's sleep because a comfortable temperature and environment that is another requirement for a good night's sleep are not created.

Therefore, recently, a product using a cold compress pack on a pillow or a pillow in which a refrigerant is formed in a certain form by injecting and sealing a refrigerant has been proposed, but the method of filling the refrigerant with a neck pillow has been structurally difficult.

The reason is that in order to manufacture a neck pillow filled with refrigerant, after the refrigerant is injected, sheets are usually superimposed to produce an adhesive method such as high frequency, but the adhesive method by high frequency is strong because only the inner surface of the overlapped sheet is adhered. Because of the fall, the load is often caused by the pressing of the pillow, or in the case of long-term use, bursting of the adhesive portion, which has weak adhesive force, often occurs.

In addition, another problem of the pillow filled with refrigerant is that it is impossible to deform the shape while the refrigerant is filled, so the pillow is produced in a uniform size according to a predetermined size, and as a result, there is a problem that it is difficult to fit each user's body shape. If the height does not fit when you go to bed, you will rather disturb your sleep.

In addition, since the material is made of a waterproof material in order to contain the refrigerant, there is a problem in that when the surface is in direct contact with the skin, sweat becomes cold and discomfort occurs.

Republic of Korea Patent Publication No. 10-2018-0029323 (2018.03.21.) Republic of Korea Registered Patent No. 10-1672972 (2016.10.31.)

The present invention is to solve the problems as described above, in the neck pillow to impart the effect of cold compress to the back of the neck by adding a coolant function built-in refrigerant material in the neck pillow, which refrigerant material is filled in the neck pillow It is intended to prevent the popping by preventing the tip from sticking to one side while firmly adhering to the adhesive portion, as well as to efficiently exchange heat by the refrigerant material.

In addition, the cushioning force of the neck pillow is excellent, and the height of the neck pillow is adjustable so that it can be used according to the user's body shape.

The present invention as a technical idea for achieving the above object, in the neck pillow consisting of a main support portion supporting the wearer's back neck, and an auxiliary support portion extended to be disposed on both shoulders of the wearer on both sides of the main support portion, the neck pillow The three sheets cut according to the size of the overlapping, and an adhesive border is formed along the border of the three sheets so that the refrigerant material and air are injected into the filling portion between the sheets, respectively, and the refrigerant inside the adhesive border The top surface is bent so that a space for filling the material is formed, so that the adhesive portions bonded in the form of dots are arranged so as to secure a ventilation path for heat exchange, so that the refrigerant material filling is not focused on either side.

In addition, it is possible to prevent the sheet adhesive portion from bursting by allowing the adhesive border to be composed of a double adhesive line, and the dot-type adhesive portion is to be sheet-bonded by the adhesive strip in the form of a circular band.

In addition, one or two sheets are further adhered between the three sheets so that the air cells into which air is injected are composed of multiple layers, and the adhesive portion for adhering the sheets is formed in a rhombus shape at positions where they are crossed, so that the refrigerant material is converged. And relieve pressure from being concentrated in one place.

According to the neck pillow for preventing the refrigerant material filling of the present invention from slipping and bursting of the sheet adhesive portion, a cold compress function is added to the user's back neck by adding a cold compress function to a conventional neck pillow, thereby improving the cardiovascular system, nervous system function, and skin You can improve your body's resistance by training.

In addition, since the refrigerant material filled in the neck pillow is isolated at each location, it is possible to prevent the load from being collected and burst to either side because the refrigerant material does not shoot to any one place, and the refrigerant material is not aggregated in the neck pillow. It can be prevented from lowering the cooling effect because it maintains an evenly spread state.

In addition, since the heat of the refrigerant exchanged with the wearer's body is discharged to the outside through the curved gap of the sheet, the body temperature can be continuously maintained through a circulating convection action. Can get a good night's sleep.

In addition, since the height of the neck pillow can be adjusted by adjusting the amount of air injection, the user can adjust the height appropriate for the user's body shape to get a good sleep, and the air filling part is divided into a number of air cells to provide buffer and support force The elasticity is very excellent and you can feel the comfort and comfort when using it in the air.

In addition, when not in use, it can be extracted and stored in a very thin thickness, so that it can be made lighter and smaller, and can be conveniently used not only indoors, but also for various outdoor activities because it is easy to store and carry.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 to 6, the neck pillow of the present invention includes a main support portion (M) for supporting the wearer's back neck, and an auxiliary support portion (S) extended to be disposed on both shoulders of the wearer on both sides of the main support portion Consisting of, the neck pillow while supporting the neck, 'C' shaped to have a relatively short length of the auxiliary support portion to prevent the neck from being excessively tilted from side to side, or 'U formed with a relatively long length of the auxiliary support portion It may be formed in a 'shaped' shape, and may be formed symmetrically or asymmetrically on both sides of the main supporting portion according to the sleeping habit of the wearer.

The main support part and the auxiliary support part of the neck pillow are filled with refrigerant material and air is injected, so that the shape of the neck pillow is filled with a circular or elliptical cross-sectional shape to be configured.

The neck pillow is composed of several sheets of 100 adhered to each other. As shown in FIG. 2, the first sheet 110, the second sheet 120, and the third sheet 130 are cut to the size of the neck pillow. A first filling part (3) in which the sheets 100 are overlapped and a refrigerant material is filled between the first sheet and the second sheet by forming an adhesive border 200 along the three sheet edges 101 ( 115), a second filling unit 125 into which air is injected may be formed between the second sheet and the third sheet.

In addition, inside the adhesive frame 200, the first sheet 110 and the second sheet 120 may be arranged in a state in which the adhesive portions 300 bonded in a dot form are arranged at regular intervals.

That is, the first filling part 125 can be formed to be partitioned to have a predetermined space by adhering the first sheet and the second sheet with the dot-shaped adhesive part 300, and the first sheet exposed to the top of the neck pillow As the curvature is formed on the upper surface of the can, it is possible to sufficiently secure a ventilation path for heat exchange.

Therefore, when the wearer uses a neck pillow, the body comes into contact with the upper surface of the first sheet. As the refrigerant material filled in the first filling part 125 comes into contact with the body, heat is absorbed by absorbing heat from the body during sleep, resulting in heat exchange. It can be lowered, and at this time, since heat is easily discharged to the outside through the curvature formed on the upper surface of the first sheet, heat exchange between the body temperature of the body and the refrigerant material can be efficiently performed.

In addition, since the first filling portion is partitioned at predetermined intervals due to the above-described dot-type adhesive portion 300, even when a vertical load is applied to the neck pillow, it is possible to prevent the refrigerant material filled in the first filling portion from being pushed to either side. You can.

In addition, an air inlet 400 may be provided at one end in order to inject air into the second filling part where air is filled.

Therefore, it is possible to minimize the storage volume without injecting air into the second filling part as usual, and can also be used as a cool mat cushion without air being injected.

In addition, it can be used by injecting air into the second filling part 125 through the air inlet 400 only when the wearer is in use, and the height of the neck pillow can be freely adjusted according to the amount of air injected, so that the body size or taste of the user can be adjusted. Therefore, it can be used in various ways.

As the sheet 100 used in the present invention, a sheet made of polyvinyl chloride may be used, and urethane other than polyvinyl chloride or light and airtight polyester, reinforced polyvinyl, synthetic rubber, or the like may be used.

On the other hand, by filling each of the inner spaces of the first filling part and the second filling part with a refrigerant material and air, the refrigerant material layer and the air layer can be distinguished, and convex surfaces made of only the refrigerant material can be formed. For this, the adhesive line 200 may be configured with a double adhesive line.

That is, as shown in Figure 3, the adhesive frame 200 is formed on the inner circumferential side and the outer circumferential side of the sheet rim 101, respectively, by forming an adhesive line 210 by an adhesive method by high frequency, etc. In the state where the material and the air are filled, the airtightness is further increased to prevent further bursting.

In addition, the adhesive portion 300, which is adhered in a dot manner, forms an adhesive strip 310 in the form of a circular band, when a vertical pressure is applied to the refrigerant material filled in the first filling portion and pressure is transferred in the lateral direction. The adhesive force is reinforced by the adhesive band so that the adhesive portion does not easily fall off.

Meanwhile, as illustrated in FIG. 7, a fourth sheet 140 may be further provided between the first sheet 110 and the second sheet 120 to divide the first filling portion up and down.

That is, the first sheet, the second sheet, and the fourth sheet may be arranged in the adhesive portion 300 is adhered in a dot form, the first filling portion 115, the filling portion is filled with refrigerant material in the state of adhesion by the bonding portion And the third filling portion 135 is filled with air may be provided to be divided up and down.

In addition, the fifth sheet 150 is further included between the second sheet 120 and the third sheet 130, and the fifth sheet is a sheet border of the second sheet 120 and the third sheet 130. It can be made to be adhered by the adhesive frame 200 adhered along, as shown in Figure 9, the first sheet, the second sheet and the fourth sheet are first adhered by the adhesive portion 300 in a dot manner In one thing, the third sheet and the fifth sheet can be produced by adhering them with an adhesive border 200 along the rim.

Therefore, since the rest of the filling part except the first filling part adjacent to the first sheet, that is, the second filling part 125, the third filling part 135, and the fourth filling part 145 can be used by injecting air, it can be used for filling the air. While the compartments are divided into a plurality of air cells, they can be supported by a plurality of support walls, and even when partial bursts occur, they are protected by the connected partition walls, thereby enabling more stable use and improving quality.

At this time, each of the air filling portions may be provided with air inlets to individually inject air, or some flow paths may be communicated to adjust the air injection amount with a small number of air inlets.

On the other hand, the adhesive portion 300 is arranged at regular intervals, that is, to be positioned at positions that are staggered with each other in the case of continuous paper or transverse, so that the adhesive portions 300 are arranged in a rhombus shape and convex while filling the central portion with refrigerant material. The first filling part and the third filling part may be formed in the same structure up and down while forming a flow path through which the refrigerant material is injected into each side of the convexly protruding part.

Therefore, in this state, when the first filling part is filled with a liquid refrigerant material, and the third filling part is injected with air, each of the liquid refrigerant materials or air is formed through a flow path formed between the adhesive parts 300 arranged in a rhombus shape. As they are gathered in a predetermined space partitioned by, the convex portion protrudes convexly to the upper side of the central portion, which the adhesive portion does not hold.

That is, as shown in FIGS. 11 and 12, in order to form the first filling portion 115, the refrigerant material is charged and charged in the first filling portion in a state in which only one side is opened while three sheets are stacked. It can be realized by adhering the side in a charged state.

In addition, as described above, the air-filling portion 400 can also be manufactured by simultaneously bonding the air inlet 400 when the side of the filling portion in which the air is filled is also opened in the same manner.

Therefore, when the refrigerant material or air is injected through the flow path between the adhesive portions, the portion to be filled bulges convexly as a whole, and the adhesive portion forming the flow path is fixed so that the pressure between the flow path becomes narrow and the pressure increases in the flow path to a relatively low height. As the refrigerant material or air is collected only in the right portion, the entire height of the bulge becomes uniform.

On the other hand, the first sheet 110 and the third sheet 130 exposed to the surface of the neck pillow are printed on the envelope sheet in a state made of a neck pillow by laminating separate outer sheets 160 on the surface as shown in FIG. 14. It is possible to provide a variety of design according to the contents, it is also possible to implement a multi-functional by a variety of functional materials such as antibacterial or scent coated on the envelope sheet.

At this time, the outer sheet 160 may use a different material from the sheet constituting the neck pillow to provide a design, such as various patterns or stationery, to provide design or various functional products.

To this end, the outer sheet 160 may be used as a fabric to prevent the stickiness of the surface when the wearer goes to bed, and in this case, when the fabric is a cotton fabric, that is, in a material having different characteristics, it is pressurized by a separate adhesive layer. It can be bonded, and in the case of a synthetic fabric woven from the same material, it can be produced by laminating by heat.
