Abstract: To obtain an excellent deodorizing and hygroscopic effect and a long-lasting refreshing sensation, a bedding element comprises a body made of cloth (1), and several deodorizer-containing pockets (2) which are provided on one side of the mat body; a deodorizer element/s (3) is/are stored in each pocket (2).

Description: The invention concerns bedding articles, particularly bedding mats and pillows, which have an outstanding deodorant and hygroscopic effect and a long-lasting refreshing feeling. Traditional mats for bedding are used to be spread on a cotton Futon (traditional Japanese mattress) or mattress, and are generally made of quilted cloths. However, the above mentioned traditional mat for bedding has problems such as the fact that it quickly loses its sensation of freshness because the mat easily absorbs odors and moisture. This is a big problem especially for bedridden elderly people and hospital patients, and it has been required to solve this problem. Also widely known are pillows for bedding consisting of a cover and pillow stuffing core made of feathers, ester cotton, buckwheat husks, polyester straws and so on. The traditional pillow for bedding, however, quickly loses its sensation of freshness because the stuffing easily absorbs odors and moisture. This problem can be solved by washing the whole pillow, but while the pillow cover is easily washed, the stuffing material is often hard to clean. This is a big problem for bedridden elderly people and hospital patients. Therefore, there was a need to design a pillow that maintained its freshness without requiring washing of the stuffing material. US-A-5 299 335 discloses a bedding article which comprises pockets and a substance contained in said pockets, as stated in the preamble of claim 1. US-A-3 638 255 teaches a cushion which contains an odor or gas-adsorbent substance. The aim of this invention is to create a bedding article that possesses an outstanding deodoring and hygroscopic effect and a long-lasting sense of freshness. The aim has been attained with a bedding article as stated in claim 1. The invention in one embodiment is carried out as a bedding mat comprising a mat body made of cloth, and a number of pockets provided on one side of the above mat body, said pockets containing deodorizers/deodorizer elements. Another feature of this invention is that the above mentioned deodorizer consists of a breathable bag (i.e. allowing air and similar to pass through) and active carbon granules inserted in the above mentioned bag. Another feature of this invention is that each of the above mentioned pockets consists of a cloth pouch having an opening for the deodorizer on one side and being sewn to one side of the mat body, the pouches being arranged in a grid pattern, the cloth of the opening part of the pouches being overlapped over each other or tucked into the pouch, so that the deodorizer cannot escape. A fourth feature of this invention is that each of the above mentioned pockets consists of a cloth pouch having openings for the above mentioned deodorizer on both sides thereof and being sewn to one side of the mat body, the pouches being arranged along the width of the above mentioned mat body, and the cloth of the opening part of each pouch being tucked into the pouch in order that the above deodorizer does not escape. The invention in a further aspect provides a pillow for bedding which has a stuffing core and a pillow cover with a pocket formed on at least one of the two sides of the pillow cover, inside of which the deodorizer is easily inserted and removed. Another pillow of the invention has a stuffing core and a pillow cover with pockets formed on both the upper and lower sides of the pillow cover, in which the deodorizer is easily inserted and removed in one side and Japanese cypress chips are inserted in the other side. A further embodiment of the invention is a pillow for bedding in which the above mentioned stuffing core consists of an upper stuffing core and a lower stuffing core, and a deodorizer is tucked between the layers of stuffing. A preferred deodorizer consists of a breathable bag containing charcoal or active carbon granules. The bedding articles of the invention provide an excellent deodorizing and hygroscopic effect that prolongs the feeling of freshness. And by overlapping the cloth of the opening of the pocket to store the deodorizer provided in the mat body, or tucking it into the above mentioned bag, the deodorizer will not escape from the pocket even if the mat is turned to any direction or overturned. Moreover, when Japanese cypress chips are tucked in the pocket, e.g. of a pillow, the fragrance of the chips is constantly released in the air and favors restful sleep. The following is an explanation of exemplary embodiments of bedding articles according to the invention, reference being made to the appended drawings, wherein: Figure 1 is a top plan view showing a first embodiment of bedding article of this invention, i.e. a bedding mat; Figure 2 is a cross-section view along line 2-2 of Figure 1; Figure 3 is a plan view of a deodorizer element which is furnished with the bedding mat of the invention; Figure 4 is a cross-section view showing another example of bedding mat; Figure 5 is a top plan view of a further embodiment of bedding article; Figure 6 is a cross-sectional view along line 6-6 in Figure 5; Figure 7 is a plan view of a deodorizer element used in the bedding article of Figure 5; Figure 8 shows a further embodiment of bedding article of the invention, in the form of a pillow, shown in an exploded partially cut-away perspective view; Figure 9 is a perspective view of another bedding pillow; Figure 10 is an exploded perspective view of another bedding pillow; Figure 11 is a cross-sectional view of the pillow of Figure 10; Figure 12 is a perspective view of a closing element of a pillow cover; Figure 13 is a cross-sectional view along line 13-13 in figure 12. In the drawings, like reference numbers refer to the same or similar elements throughout. In figures 1-3 a bedding article of the invention is a bedding mat referenced 10 and comprises a mat body 1 made of cloth, several pieces of pockets 2 (21 pieces in this example) to store the deodorizer which are provided on one side of the mat body 1; a deodorizer element is stored inside each pocket 2. The deodorizer element 3 consists of a bag 3A made of a "breathable" paper (i.e. a paper or paper-like material allowing air or similar to pass through it) or fiber and active carbon granules 3B contained in the bag 3A, as shown in Figure 2. Of course, another material may be used instead of active carbon granules - such as charcoal granules and so on - as long as it has deodorizing and hygroscopic properties. The bag 3A is divided into several sections (four sections in this example), as shown in Figure 3, to prevent the active carbon granules 3B from being unevenly distributed inside the bag 3A. The pocket 2 consists of a cloth bag or pouch for the deodorizer 3 that has an opening at an edge of it, which is sewn on one side of the mat body 1. The above mentioned sections of pouches are arranged in grid patterns, and cloth 2A and 2B of the above mentioned opening part are overlapped in order to prevent the deodorizer 3 from escaping when the mat body 1 is moved in various directions. When the deodorizing effect decreases, its deodorizing and hygroscopic properties can be renewed by taking the deodorizer element 3 out of the pocket 2 and washing and drying it, because the deodorizer 3 can be easily inserted and removed from the pocket. On the other hand, the mat body 1 can also be washed separately from the deodorizer 3, therefore, this is especially favorable for the patient. The cloth 2A of the opening part of the pocket 2 may be tucked into the above mentioned pouch, as shown in Figure 4, in order to prevent the deodorizer 3 from escaping when the mat body 1 is moved in various directions. Figures 5-7 show another practical example of this invention. A mat for bedding 20 in this practical example comprises a number of pockets 22 consisting of cloth bags or pouches to store a deodorizer 23, the pouches being provided along the width of the mat body 21. Openings are provided at both edges of each pouch, and the cloth 22A of the opening part is tucked into the pouch to prevent the deodorizer 3 from escaping. When the deodorizer 23 is removed from the above mentioned pouch, the cloth 22A of the opening part of the above bag should be taken out of the bag as the dotted line shows in Figure 6. As shown in Figures 6 and 7, the deodorizer 23 to be stored inside the above mentioned bags is composed of several pieces (four pieces in this example) of the deodorizer in Figure 3 which are arranged in a row. Since the several pieces of deodorizer are linked together in this mat, the deodorizer 23 can be efficiently removed and inserted in a short time. Since the deodorizer 23 is furnished with the mat body 21 as mentioned before, the odors and moisture are sufficiently absorbed by the outstanding deodorant and hygroscopic properties of the active carbon 23. As a result, the refreshing sensation of the mat body 21 lasts over a long period of time. Furthermore it provides an effect to recover from one's fatigue because the unevenness of the mat body 21 caused by the deodorizer 23 stimulates the acupunture points of the body during sleeping. Furthermore it creates a good ventilation of the mattress because it establishes a situation similar to one which the deodorizer would lay inside the mattress. Moreover, since the cloth of the opening part of the pocket is overlapped or tucked in towards the inside, there is no fear that the deodorizer can escape from the pocket whatever the direction of the mat. In addition, various serviceable types - such as recovering from one's fatigue during sleeping and so on - can be expected because the uneveness caused by the deodorizer stimulates the acupuncture points of the person's back. In Figure 8, reference 30 is a bedding article of the invention, in form of a pillow. Reference 31 is a pillow stuffing core that is composed of feathers, ester cotton, buckwheat husks, small polyester straws and so on that are inserted inside a cloth bag. The number of core stuffing 31 is not limited to one. In fact, the pillow height can be freely regulated by adjusting the number of stuffing cores 31 inserted inside the pillow cover. In this case, the stuffing core material can be changed and a suitable combination of different materials for the stuffing core 31 can be used. Reference 32 is a pillow cover made of cloth which covers the pillow stuffing core 31 and whose opening is made in such a way that it can be freely opened and closed with a fastener, referenced 35. Pockets 33 are formed on at the upper side (the side on which the head is placed) or the lower side (the side which faces the mattress) of the pillow cover 32 on both (in this example, three pockets are provided on one side). A deodorizer element 34 is inserted inside each of the pockets 33 in a way that it can be easily inserted and removed. The deodorizer 34 consists of a bag 34A that is made of a breathable non-fabric or paper fiber and the active carbon granules 34B which is inserted in the bag 34A. Of course, another material may be used instead of active carbon granules - such as charcoal granules and so on- as long as it has deodorizing and hygroscopic properties. As shown in Figure 1, the bag 34 A is divided into a number of sections (four sections in this example) that are distributed along the length of the pillow to prevent the active carbon granules inside the bag 34A from being unevenly distributed. Since active carbon granules have excellent deodorizing and hygroscopic properties, odors and moisture are quickly and efficiently absorbed by the active carbon granules 34B that prevent the odors and moisture from being absorbed by the stuffing core 31. The active carbon granules 34B can be replaced with new ones when their deodorizing and hygroscopic properties decrease, because the active carbon granules 34B can be easily inserted and removed from pocket 33. As a result, the refreshing sensation of the pillow lasts over a long period of time. The deodorizer 34, apart from being inserted in the pocket of one of either sides of the pillow cover as mentioned above, can be also inserted in the pockets of both sides of the pillow cover 32. As shown in pillow 40 of Figure 9, pockets are formed on both sides of pillow cover 42. The deodorizer, which is the same as above (not shown in the drawing), is placed inside a pocket (not shown in the drawing) on one side in a way that it can be easily inserted and removed, while Japanese cypress chips fill a mesh pocket on the other side. The chips release the fragrance of Japanese cypress throughout and favor restful sleep. The other elements and properties are the same as those mentioned for the first embodiment. As shown in Figures 10 and 11, a pillow 50 comprises a stuffing core that is divided into two sections; an upper stuffing core layer 51A and a lower stuffing core layer 51B. The deodorizer 54 is inserted between the upper stuffing core layer 51A and lower stuffing core layer 51B. Both are covered by the cloth pillow cover 52 which has the shape of a bag. The pillow cover opening can be easily opened and closed by the fastener 57. Besides using the fastener 57, the pillow cover can be closed by prolonging the cloth 62B of one of the edges of a pillow cover 62 opening and folding this cloth 62B over to the opposite side, as shown in Figures 12 and 13 for pillow 60. This can be applied to the other embodiments in the same way. the deodorizer 54 is inserted into more than one pocket section (there are three sections in this example) that are formed by sewing together two pieces of cloth. The composition of deodorizer is the same as mentioned earlier. In the pillow of figures 10-11, the deodorizer 54 does not directly come into contact with the head as it does in the pillows of figures 8, 9. as a result, the head cannot feel the unpleasant bumpiness of the deodorizer granules 54. The other effects are the same : i.e. a long-lasting, refreshing sensation due to the outstanding deodorizing and hygroscopic properties of the charcoal or active granules and to the Japanese cypress chips that are inserted in the pockets of the pillow, which create a certain useful effect because the pleasant fragrance of Japanese cypress is always released from the chips and favors restful sleep.
