Abstract

<P>PROBLEM TO BE SOLVED: To provide a pillow with excellent portability which is easily carried when it is not used, adjusted in height when it is used, and returned to a state equal to that when it is not used, after usage. <P>SOLUTION: The pillow 1 is formed by storing a granular polymer absorbent 3 in a bag body 4 made of water-permeable nonwoven fabric 2, so as to be in a sealed state. When the pillow 1 is immersed in fresh water W, the polymer absorbent 3 absorbs water permeated into the bag body 4 and the whole pillow 1 is gradually expanded, so as to be used in a way being the same as that of a normal pillow. The height of the pillow 1 is adjusted by changing the immersion time in the fresh water W, so as to increase/decrease the water absorption amount of the polymer absorbent 3 and to adjust the degree of expansion. When the pillow 1 expanded by absorbing water is immersed in salt water SW, the polymer absorbent 3 is gradually contracted by losing water, so as to be restored to a light nonbulky original sheet. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a pillow used at the time of sleeping or resting, which is easy to carry and can be adjusted in height.

  When staying at an accommodation facility such as a hotel on a business trip or traveling, a pillow provided in the bedroom is usually used, but if the comfort of the pillow is poor, it will not be possible to sleep well, and an unpleasant morning will be greeted. Some hotels offer several types of pillows to prevent such inconveniences, but the preference for pillow height and hardness varies greatly depending on the individual, so it meets the needs of all guests. It is impossible to arrange pillows.

  For this reason, as a self-defense measure, there are people who carry their own pillows and portable pillows on business trips and travel, but normal pillows are bulky and inconvenient to carry. It is uncomfortable to use because there is only a method of inflating with air when in use. Also, when going out for leisure, such as camping, mountain climbing, fishing, etc., you may want to bring a pillow, but the reality is that there is no pillow that is easy to carry and comfortable to use.

  On the other hand, pillows in which a polymeric water-absorbing agent that expands by absorbing moisture is housed in a bag have been developed as pillows for newborns or water pillows (see, for example, Patent Documents 1 and 2).

JP-A-11-137394 (page 2-4) JP-A-5-317350 (page 2-3)

  The pillow for a newborn described in Patent Document 1 is a gel-like water absorbent by adding water to a highly water-absorbing polymer material housed in a semicircular bag, and the bag sinks evenly due to the weight of the head of the newborn. Although the pressure is applied, the height of the pillow cannot be adjusted, and since it has a certain volume and weight by absorbing moisture, it is not easy to carry.

  The water pillow described in Patent Document 2 is convenient for carrying because it is not bulky before the polymer water-absorbing agent absorbs moisture, and the height can be adjusted by adjusting the amount of water absorption. After that, since the weight and volume increase, it is inconvenient to carry and is actually disposable once. Moreover, after use, it is not preferable from the viewpoint of environmental protection because it must be disposed of as combustible waste or the bag is torn and the contents are poured into a drain pipe and discarded.

  The problem to be solved by the present invention is to provide a pillow that is easy to carry when not in use and excellent in portability, can be adjusted in height when used, and can be returned to the same state when not in use. It is to provide.

  The pillow of the present invention is formed of a sheet material having at least a part of a water-permeable polymer water-absorbing agent that expands by absorbing moisture when contacted with fresh water and loses moisture when contacted with salt water. It is characterized by being formed in a sealed state in a bag.

  By adopting such a configuration, when not in use, since the powdered polymer water-absorbing agent is contained in a bag formed of a sheet material, it is light and not bulky, easy to carry and portable Is excellent. When using it, if it is immersed in fresh water as it is, the polymer water-absorbing agent that has absorbed the moisture that has penetrated into the bag through the water-permeable portion of the sheet material will gel and expand, so that the appropriate size If the pillow is lifted from the water when it is expanded and the water droplets on the surface of the bag are wiped off, it can be used in the same manner as a normal pillow. Moreover, the height of the pillow can be adjusted by changing the immersion time in fresh water to increase or decrease the amount of moisture absorption.

  In addition, if cold water, such as well water, ground water, and clear water, is used as the fresh water for immersion, a pillow with a cool and cool feeling can be formed. In addition, if the fresh water cooled in the refrigerator is absorbed or the expanded pillow is cooled in the refrigerator, it can be used as a so-called “water pillow (ice pillow)”, so that it is effective even during sudden heat generation.

  After use, if the whole pillow is immersed in salt water as it is, the salt water that has entered the bag through the water-permeable part comes into contact with the polymer water-absorbing agent, and the moisture contained in the polymer water-absorbing agent by osmotic pressure. Take away. As a result, the polymer water-absorbing agent gradually contracts and finally returns to a granular state, so that the pillow returns to the original sheet state that is lightweight and not bulky. In this way, after use, it can be returned to the same state as when not in use, so it becomes portable and convenient. In addition, since this pillow can be repeatedly expanded by immersing in fresh water and contracted by immersing in salt water, it is not disposable only once, but can be used repeatedly about 3 to 4 times, which is also beneficial for environmental protection. is there.

  In addition, as a sheet | seat material in which at least one part has water permeability, a water-permeable nonwoven fabric is suitable, for example. In this case, if the entire bag body is formed of such a nonwoven fabric, the entire surface of the bag body has water permeability, so that the permeability of fresh water and salt water is increased, and the pillow is expanded and contracted in a short time. Will be able to.

  On the other hand, a granular material containing at least one of far-infrared radiation material, negative ion radiation material, aromatic material, plant charcoal, activated carbon in the bag body or a non-permeable region provided in the bag body. It can also be accommodated. Accommodating granular materials containing such substances will provide a comfortable and good-quality sleep because the pillow will exhibit far-infrared light generation function, negative ion generation function, aroma generation function or deodorization / deodorization function. Will be able to.

  Although the granular material of these substances can be accommodated in the bag together with the polymer water-absorbing agent, it can also be accommodated in a non-permeable region provided in the bag. If the granular material of these substances is contained in the non-permeable region, even when the pillow is immersed in fresh water or salt water, fresh water or salt water does not enter the non-permeable region. Can be prevented. In addition, in order to ensure the aroma generating function or the deodorizing / deodorizing function, it is desirable that the non-water-permeable region has air permeability.

  Further, at least one of a plant granule, a mineral granule, a synthetic resin tubular body, and a synthetic resin granule is accommodated in the bag body or a non-permeable region provided in the bag body. You can also. If these substances are contained in the bag or a non-permeable region provided in the bag, when the head is placed on the pillow, it cannot be obtained only by the water-absorbing polymer water absorbent, a unique feel or general Because it feels like a pillow, you can get a comfortable and good-quality sleep. As described above, if the granular materials of these substances are accommodated in the water-impermeable region, even when the pillow is immersed in fresh water or salt water, fresh water or salt water does not enter the water-impermeable region. Alteration and deterioration can be prevented, and the feel of vegetable granules, mineral granules, synthetic resin tubular bodies, or synthetic resin granules that are not affected by the polymer absorbent can be obtained.

  The present invention has the following effects.

(1) A polymeric water-absorbing agent that absorbs moisture when contacted with fresh water and expands, and loses moisture when contacted with salt water and becomes powdery, is formed into a bag formed of a sheet material having at least a part of water permeability. Because it is housed in a sealed state, it is lightweight and not bulky when not in use, is easy to carry and has portability, and can be adjusted in height when in use. Because it can be returned to, it is convenient.

(2) Granules containing at least one of a far-infrared emitting substance, a negative ion emitting substance, an aromatic substance, a vegetable charcoal, and activated carbon in the bag or a non-permeable region provided in the bag. If the pillow is accommodated, the pillow will exhibit a far infrared ray generation function, a negative ion generation function, an aroma generation function, or a deodorization / deodorization function, so that a comfortable and high quality sleep can be obtained.

(3) Accommodating at least one of plant granules, mineral granules, synthetic resin tubular bodies, and synthetic resin granules in the bag or a non-permeable region provided in the bag. In this case, when the head is placed on the pillow, a unique feel that cannot be obtained only with the absorbed polymer water-absorbing agent can be obtained, which is effective in obtaining a comfortable and good-quality sleep.

  1 is a partially cutaway perspective view showing a pillow according to a first embodiment of the present invention, FIG. 2 is an explanatory view showing a handling procedure when using the pillow shown in FIG. 1, and FIG. It is explanatory drawing which shows the handling procedure after use of the pillow shown in FIG.

  The pillow 1 of this embodiment is formed by containing a granular polymer water-absorbing agent 3 in a sealed state in a bag 4 formed of a nonwoven fabric 2 having water permeability. The outer peripheral edge and the inner part of the bag body 4 are sewn by perforations 5. As will be described later, the polymer water-absorbing agent 3 accommodated in the bag body 4 absorbs moisture when it comes into contact with fresh water and gels and expands, and when it comes into contact with salt water, it loses moisture and becomes granular. I have.

  When not in use, the pillow 1 is in a state in which the granular polymer water-absorbing agent 3 is accommodated in the bag 4 made of the nonwoven fabric 2, and the polymer water-absorbing agent 3 has a volume equal to or less than the volume of the bag 4. Lightweight, not bulky and easy to carry. For this reason, it can be easily carried when going out for leisure such as camping, mountain climbing and fishing, and is convenient.

  When using the pillow 1, if the pillow 1 in a dry state as shown in FIG. 3 (a) is immersed in fresh water W as it is for about 3 to 5 minutes as shown in FIG. 3 (b), Since the polymer water-absorbing agent 3 absorbs moisture that has passed through the nonwoven fabric 2 constituting the bag body 4 and absorbed into the bag body 4, the gel expands and the volume expands. It expands. When the pillow 1 is lifted from the fresh water W when it is expanded to an appropriate size and the water droplets on the surface of the bag body 4 are wiped off, the state shown in FIG. Can do.

  Moreover, the height of the pillow 1 can be adjusted by changing the immersion time in the fresh water W to increase or decrease the water absorption amount of the polymer water-absorbing agent 3 to adjust the degree of expansion. Therefore, it is possible to make the height suitable for the user's preference, and the usability is also good. In addition, although the nonwoven fabric 2 has water permeability, since the water | moisture content which the polymeric water absorbing agent 3 hold | maintains by the external pressure added to the pillow 1 in use does not ooze out through the bag body 4, bedding in use The situation where the head gets wet with water does not occur.

  The non-woven fabric 2 constituting the bag body 4 does not break even when a human weight is applied unless a sharp blade or a cone is applied, so that the gelled polymer water-absorbing agent 3 leaks out during use as a pillow. There is nothing to do. Moreover, if cold water, such as well water, ground water, and clear water, is used as the fresh water W for immersion, the pillow 1 has a refreshing and cool feeling. In addition, if the fresh water W cooled in the refrigerator is absorbed or the expanded pillow 1 is cooled in the refrigerator, it can be used as a so-called “water pillow (ice pillow)”, so it is effective even when sudden heat generation occurs. .

  After the use as a pillow is finished, the pillow 1 is in an expanded state as shown in FIG. 3A, but as shown in FIG. If immersed in about 5% to 10 minutes in salt water SW of about 5% by weight, the salt water SW that has entered the bag body 4 through the nonwoven fabric 2 constituting the bag body 4 comes into contact with the polymer water-absorbing agent 3, Since the polymer water-absorbing agent 3 gradually loses moisture and contracts, the pillow 1 gradually contracts. And finally, since the polymer water-absorbing agent 3 returns to the original powder form, the pillow 1 returns to the original state of being light and not bulky as shown in FIG.

  Thus, since the pillow 1 after use can be returned to the same state as when not in use by being immersed in the salt water SW, it is portable and convenient. Moreover, since it is possible to repeat the expansion | swelling by immersion in the fresh water W shown in FIG. 2, and the shrinkage | contraction by immersion in the salt water SW shown in FIG. It can be used repeatedly about once and is also beneficial for environmental protection.

  In addition, since the expansion by immersion in fresh water W and the contraction by immersion in salt water SW can be easily performed in the bathroom of a hotel or inn if you carry salt, the pillow 1 is portable for business trips and travel. It is very convenient as a pillow. It can also be easily carried when going out for leisure such as camping, mountain climbing and fishing.

  In this embodiment, when “(trade name) Elves TO503” manufactured by Unitika Co., Ltd. was used as the nonwoven fabric 2 constituting the bag body 4, the strength was excellent and the usability was also good. Moreover, when “(trade name) Sunwet” manufactured by Mitsubishi Chemical Corporation was used as the polymer water-absorbing agent 3, the water-absorbing property and the dehydrating property were good, and rapid expansibility and shrinkability were obtained.

  Next, with reference to FIG. 4, the pillow 6 which is 2nd Embodiment of this invention is demonstrated. In FIG. 4, the portions denoted by the same reference numerals as those in FIGS. 1 to 3 are portions exhibiting the same functions and effects as those of the pillow 1 described above, and description thereof is omitted.

  In the pillow 1 described above, only the granular polymer water-absorbing agent 3 is housed in a sealed state in the bag body 4, but in the pillow 6 of this embodiment, the polymer water-absorbing agent 3 is contained in the bag body 4. The granular material 7 containing a far-infrared emitting material is accommodated in a sealed state.

  The pillow 6 is used in exactly the same way as the pillow 1 described above. When the pillow 6 is immersed in fresh water W, the water absorbed through the nonwoven fabric 2 is absorbed by the polymer water-absorbing agent 3 and expanded, and the expanded pillow 6 is changed to salt water SW. When immersed in, the polymer water-absorbing agent 3 loses moisture due to salt water that has permeated through the nonwoven fabric 2 and contracts. Therefore, it can be used in the same manner as the pillow 1, and the same functions and effects can be obtained.

  In the pillow 6, since the granular body 7 containing the far-infrared emitting material together with the polymer water-absorbing agent 3 is accommodated in the bag body 4, a comfortable sleep is obtained by the far-infrared radiation emitted from the granular body 7 during use. Can do. In addition to the granular material 7, the bag 4 can also accommodate a granular material containing a negative ion emitting material, an aromatic material, vegetable charcoal, activated carbon, or the like. If the granular material containing such a substance is accommodated, the pillow 6 will exhibit a negative ion generation function, an aroma generation function, or a deodorization / deodorization function, which is effective in obtaining a comfortable and good quality sleep. is there.

  Moreover, if a vegetable granule, a mineral granule, a synthetic resin tubular body, a synthetic resin granule, etc. are accommodated in the bag body 4 constituting the pillow body 6, when the head is placed on the pillow, the water absorption Thus, a unique feel that cannot be obtained only by the polymer water-absorbing agent 3 is obtained, so that it is comfortable for a person who likes such a feel.

  Next, with reference to FIG. 4, the pillow 10 which is 3rd Embodiment of this invention is demonstrated. In FIG. 4, the portions denoted by the same reference numerals as those in FIGS. 1 to 3 are portions exhibiting the same functions and effects as those of the pillow 1 described above, and description thereof is omitted.

  In the pillow 10 of this embodiment, one side is formed of the nonwoven fabric 2, the other side is formed of a water-impermeable sheet 11 having air permeability, and the inside of the bag body 12 is partitioned by the water-impermeable sheet 11. The polymer water-absorbing agent 3 is accommodated in one water-permeable region 13 in a sealed state, and the mineral granular material 15 and the aromatic granular material 16 having a negative ion generating function are accommodated in the other non-permeable region 14. Yes.

  When the pillow 10 is immersed in fresh water W, the polymer water-absorbing agent 3 absorbs the water permeated through the nonwoven fabric 2 and expands. When the expanded pillow 1 is immersed in the salt water SW, the polymer water-absorbing agent 3 is absorbed by the salt water transmitted through the nonwoven fabric 2. Since it loses moisture and contracts, it can be used in the same manner as the pillow 1, and the same functions and effects can be obtained.

  In the pillow 10, the mineral particles 15 and the aromatic particles 16 having the function of generating negative ions are accommodated in the water-impermeable region 14, so that the negative ions and aromas are passed through the air-impermeable sheet 11 having air permeability. Will be generated, and comfortable and good quality sleep can be obtained. Further, since the mineral granular material 15 and the aromatic granular material 16 are accommodated in the water impermeable region 14, even if the pillow 10 is immersed in fresh water W or salt water SW, Since salt water does not enter, alteration and deterioration of the mineral granular material 15 and the aromatic granular material 16 due to moisture can be prevented.

  Further, since the mineral granular material 15 and the aromatic granular material 16 are accommodated in the water impermeable region 14 independently from the polymer water-absorbing agent 3, if the head is placed with the water impermeable region 14 facing up, Since the unique feel of these granular materials 15 and 16 can be directly obtained without being affected by the polymer water-absorbing agent 3, it becomes comfortable for those who like it.

  In addition to the mineral particles 15 and the aromatic particles 16, the materials contained in the water-impermeable region 14 include far infrared radiation materials, negative ion radiation materials, aromatic materials, vegetable charcoal, activated carbon, and the like. It is also possible to accommodate granules or plant granules, synthetic resin tubular bodies, synthetic resin granules and the like.
