Benefits of technology

[0010] As a result of extensive study for solving these problems, the present inventors surprisingly found that, by using as a filler a mixture of expanded resin beads having a low content of solvent and aroma-containing beads and sealing the mixture into a bag, there can be provided a faintly aromatic cushioning body which has an aroma capable of exhibiting a relaxation or aromatherapy effect as well as a preferable touch or feel and in which occurrence of an unusual sound is suppressed, thus arriving at the present invention.

Problems solved by technology

SHO 56(1981)-115966 have a problem that, when used as a bed, a mattress, a pillow, a cushion or the like which cushions a human body, the cushioning bodies cause an unusual sound every time a human body moves to give the user discomfort or wake the user to the unusual sound while he is in bed.
However this demand is not yet satisfied fully by any cushioning bodies provided so forth.
Further, the cushioning body may not have a desired aroma, since it has other smell than an aroma from the aromatic agent.

example 1

[0075] 120 g of tricalcium phosphate (trade name: calcium tertiary phosphate, manufactured by Taihei Kagaku Co., Ltd.), 0.24 g of sodium hydrogen sulfite and 0.24 g of potassium persulfate were introduced into a 100-L autoclave, and 133 g of benzoyl peroxide (purity 75%, trade name: Niper BW, manufactured by Nippon Oil and Fats Co., Ltd.), 56 g of t-hexylperoxy isopropyl monocarbonate (purity 90%, trade name: Perhexyl I, manufactured by Nippon Oil and Fats Co., Ltd.), 40 kg of deionized water and 40 kg of styrene monomer which contains a solvent of 264 ppm other than styrene were further introduced into the mixture, dissolved and suspended under stirring to prepare a suspension.

[0076] Then, the styrene monomer was subjected under stirring at 200 rpm to polymerization reaction in the autoclave at 90° C. for 8 hours and then at 125° C. for 3.5 hours. After the reaction was finished, the reaction mixture was cooled, removed from the autoclave, centrifuged and dried to give styrene res...

example 2

[0082] A faintly aromatic cushioning body was obtained in the same manner as Example 1 except that the expanded resin beads were dried at 60° C. The results are shown in Table 1.

example 3

[0083] A faintly aromatic cushioning body was obtained in the same manner as Example 1 except that the expanded resin beads were dried at 60° C. for seven days. The results are shown in Table 1.

Abstract

A faintly aromatic cushioning body comprising: a mixture of expanded resin beads and aroma-containing beads, the expanded resin beads having a solvent of 400 ppm or less and an average particle diameter of 0.4 to 1.4 mm, wherein the mixture of expanded resin beads and aroma-containing beads is used as a filler into a bag.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application is related to Japanese application No. 2004-89660 filed on Mar. 25, 2004, whose priority is claimed under 35 USC § 119, the disclosure of which is incorporated by reference in its entirety. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a faintly aromatic cushioning body. More particularly, it relates to a faintly aromatic cushioning body which can be suitably used as a bed, a mattress, a pillow, a stuffed toy, a cushion, a toy, a cushioning medium and the like, which have a faint aroma. [0004] 2. Description of Related Art [0005] As conventional cushioning bodies, cushioning bodies using cotton, feathers, non-rigid urethane foam, resin beads and the like are generally known. Among these, as cushioning bodies using resin beads, Japanese Examined Utility Model Publication No. HEI 3(1991)-45641 discloses a cushioning body in a matt form using as fillers styrene foam bea...
