Abstract
Description
本発明は、袋体に充填されて、枕やクッション、玩具などに用いられるクッション体用充填剤及びクッション体に関する。 The present invention relates to a filler for a cushion body and a cushion body which is filled in a bag and used for a pillow, a cushion, a toy or the like.
従来、枕やクッション、玩具などに用いられるクッション体としては、袋体の中にビーズと呼ばれる発泡合成樹脂粒子を充填剤として封入したものが広く知られている。従来の充填剤には、一般的に発泡合成樹脂粒子が用いられているため、クッション体に荷重を加えるとビーズが変形して、ビーズの流動性が低下する。そのため、ビーズの流動性を向上させてクッション体の手触りや触感をよくするために、ビーズと共に流動促進剤を袋体に封入したクッション体が提案されている（例えば、特許文献１及び特許文献２参照）。 Heretofore, as cushion bodies used for pillows, cushions, toys, etc., those in which foam synthetic resin particles called beads are enclosed as a filler in a bag body are widely known. Since foamed synthetic resin particles are generally used for conventional fillers, when a load is applied to the cushion body, the beads are deformed and the fluidity of the beads is reduced. Therefore, in order to improve the fluidity of the beads to improve the feel and feel of the cushion body, cushion bodies in which a flow promoter is enclosed in a bag together with the beads have been proposed (for example, Patent Document 1 and Patent Document 2) reference).
従来の充填剤は、長期間の使用によりビーズの気泡が破壊されたり形状が変形したりして、クッション体のボリューム感やクッション性が低下する、いわゆる「へたり」が発生していた。また、従来の充填剤は、クッション体の手触りや触感をよくするために、ビーズの粒子径を小さくしたり、流動促進剤を添加したりしてビーズの流動性を向上させたことにより、クッション体の安定感を損なっていた。 In the conventional filler, so-called “settle” occurs in which the air bubbles of the beads are broken or the shape is deformed due to long-term use, and the volume feeling and the cushioning property of the cushion body are reduced. In addition, the conventional filler improves the fluidity of the beads by reducing the particle size of the beads or adding a flow promoter to improve the feel and feel of the cushion body. I was losing my sense of stability.
特許文献３には、袋体の中に、ポリスチレン樹脂を発泡させて成形した発泡ポリスチレンビーズと、低反発合成樹脂のポリウレタン樹脂を粉砕したポリウレタン粒子を充填し、いわゆる「へたり」を防止すると共に、安定感を向上させたクッション体が開示されている。 In Patent Document 3, foam bags filled with expanded polystyrene beads formed by expanding polystyrene resin and polyurethane particles obtained by crushing polyurethane resin of low resilience synthetic resin are filled in a bag to prevent so-called "settle". There is disclosed a cushion body with an improved sense of stability.
クッション体において、ビーズの粒子径を小さくすると、ビーズの動きが滑らかになり触感が向上することは知られている。しかし、従来のクッション体は、ビーズに気泡を含む発泡合成樹脂粒子が用いられているため、ビーズの粒子径を微小に成形するのが困難であるのみならず、ビーズが変形して流動性の低下と「へたり」が生じ、触感が低下するという課題があった。 In the cushion body, it is known that the smaller the particle size of the beads, the smoother the movement of the beads and the better the feel. However, since the conventional cushion body uses foamed synthetic resin particles containing bubbles in the beads, it is difficult not only to form the particle size of the beads minutely, but also the beads are deformed to be fluid. There is a problem that a drop and a "stagnation" occur and the touch feel is reduced.
そこで、本発明は、極小ビーズによる肌触りの良さに加えて、しっとり感を兼ね備えた触感の良好なクッション体を実現できるクッション体用充填剤及びクッション体を提供するものである。 Therefore, the present invention is to provide a filler for a cushion body and a cushion body which can realize a cushion body having a good feeling of touch and having a moist feeling in addition to the goodness of touch by the very small beads.
本発明は、上記課題を解決するために、袋体に充填されるクッション体用充填剤であって、平均粒子径０．０５〜１ｍｍの合成樹脂粒子と、天然ゴム又は合成ゴムを発泡させた発泡体を粉砕した粉砕発泡体と、を含むクッション体用充填剤を提供するものである。 MEANS FOR SOLVING THE PROBLEMS The present invention is a filler for a cushion body filled in a bag, in order to solve the above-mentioned problems, wherein synthetic resin particles having an average particle diameter of 0.05 to 1 mm and natural rubber or synthetic rubber are foamed. It is intended to provide a filler for a cushion body, which comprises a crushed foam obtained by crushing foam.

また、本発明は、上記のクッション体用充填剤を、伸縮性を有する袋体に充填したクッション体を提供するものである。 The present invention also provides a cushion body in which the above-mentioned filler for a cushion body is filled in an elastic bag.
本発明のクッション体用充填剤は、袋体に充填されるクッション体用充填剤であって、平均粒子径０．０５〜１ｍｍの合成樹脂粒子と、天然ゴム又は合成ゴムを発泡させた発泡体を粉砕した粉砕発泡体と、を含むことにより、極小合成樹脂粒子の滑らかな動きによる肌触りの良さに加えて、弾力性のある粉砕発泡体によって、しっとり感を兼ね備えた良好な触感を得ることができる効果がある。 The filler for a cushion body according to the present invention is a filler for a cushion body filled in a bag, and is a foam obtained by foaming natural rubber or a synthetic rubber, and synthetic resin particles having an average particle diameter of 0.05 to 1 mm. In addition to the goodness of the touch by the smooth movement of the minimal synthetic resin particles by containing a crushed foam obtained by pulverizing, it is possible to obtain a good touch having a moist feeling by the elastic crushed foam. There is an effect that can be done.
また、本発明は、袋体に充填されるクッション体用充填剤であって、ポリスチレン樹脂を含む合成樹脂粒子と、ポリウレタン樹脂を発泡させた発泡体を粉砕した粉砕発泡体と、を含むことにより、荷重を加えても変形し難い合成樹脂粒子による動きの滑らかさと、粉砕発泡体による弾力性によって、肌触りの良さとしっとり感を兼ね備えた良好な触感を得られると共に、粒子の「へたり」を防止することができる効果がある。 Further, the present invention is a filler for a cushion body filled in a bag, which comprises synthetic resin particles containing a polystyrene resin, and a pulverized foam obtained by pulverizing a foam in which a polyurethane resin is foamed. Due to the smoothness of movement by synthetic resin particles that are difficult to be deformed even when a load is applied and the elasticity by crushed foam, a good touch feeling with both good touch and moist feeling can be obtained, and "swelling" of particles There is an effect that can be prevented.
また、本発明のクッション体用充填剤は、前記合成樹脂粒子が未発泡状態の発泡性ポリスチレン樹脂粒子であることにより、合成樹脂粒子は軽量で剛性が高く、いわゆる「へたり」が生じ難く、触感の良さを持続することができる効果がある。 Further, in the filler for a cushion body of the present invention, since the synthetic resin particles are foamable polystyrene resin particles in a non-foamed state, the synthetic resin particles are light in weight and high in rigidity, and so-called "settle" hardly occurs. It has the effect of maintaining good tactile feel.
また、本発明のクッション体用充填剤は、前記発泡体が１倍を超えて１０倍以下の発泡倍率でポリウレタン樹脂を発泡させたことにより、発泡体の弾力性によって、しっとり感を得ることができる効果がある。 In addition, the cushioning material filler of the present invention can obtain a moist feeling due to the elasticity of the foam by foaming the polyurethane resin at a foaming ratio of 10 times or less than the foam of more than 1 time. There is an effect that can be done.
また、本発明のクッション体は、上記のクッション体用充填剤を、伸縮性を有する袋体に充填したことにより、流動性のよい微小粒子と相まって自在かつ速やかに変形するから、良好な触感を得ることができる効果がある。 In addition, the cushioning body of the present invention can be freely and rapidly deformed by being filled with the above-mentioned filler for cushioning body in a bag having elasticity, so that it can freely and rapidly be deformed, so that a good feeling of touch can be obtained.

And.
また、本発明は、袋体に充填されるクッション体用充填剤であって、ポリスチレン樹脂を含む合成樹脂粒子と、ポリウレタン樹脂を発泡させた発泡体を粉砕した粉砕発泡体と、を含むものである。 Further, the present invention is a filler for a cushion body filled in a bag, which comprises synthetic resin particles containing a polystyrene resin, and a pulverized foam obtained by pulverizing a foam obtained by foaming a polyurethane resin.
本発明のクッション体は、伸縮性を有する袋体に、球状に成形された合成樹脂粒子と、天然ゴム又は合成ゴムを発泡させた発泡体を粉砕した粉砕発泡体と、を充填したものである。 The cushioning body of the present invention is obtained by filling an elastic bag body with spherically shaped synthetic resin particles and a crushed foam obtained by crushing a natural rubber or a foam obtained by foaming a synthetic rubber. .
本実施例において、合成樹脂粒子には、未発泡状態の発泡性ポリスチレン樹脂粒子を用いている。発泡性ポリスチレン樹脂粒子は、軽量で剛性の高いポリスチレン樹脂を含んだものであればよく、ポリエチレン樹脂を加えて耐衝撃性を高めたものでもよい。 In the present embodiment, foamable polystyrene resin particles in an unfoamed state are used as the synthetic resin particles. The expandable polystyrene resin particles may be any one containing light weight and high rigidity polystyrene resin, and may be one to which polyethylene resin is added to enhance impact resistance.
合成樹脂粒子には、未発泡状態の発泡性合成樹脂粒子の他、ポリスチレン樹脂、ポリエチレン樹脂、ポリプロピレン樹脂などの合成樹脂を球状に形成したものを用いてもよい。 As the synthetic resin particles, in addition to the foamable synthetic resin particles in the non-foamed state, spherical synthetic resin such as polystyrene resin, polyethylene resin, polypropylene resin may be used.
本実施例において、粉砕発泡体は、ポリウレタン樹脂を発泡させた発泡体を細かく粉砕して形成したものである。発泡体は、１倍を超えて１０倍以下の発泡倍率でポリウレタン樹脂を発泡させていることが好ましく、１倍を超えて５倍以下の発泡倍率で発泡させていることがより好ましい。また、粉砕発泡体は、発泡ポリウレタン樹脂を平均粒径０．０７〜０．２ｍｍに粉砕していることが好ましい。 In the present example, the crushed foam is formed by finely crushing a foam obtained by foaming a polyurethane resin. The foam preferably has a polyurethane resin foamed at a foaming ratio of more than 1 and 10 or less, and more preferably more than 1 and 5 or less. Moreover, it is preferable that a grinding | pulverization foam is grind | pulverizing foaming polyurethane resin to an average particle diameter of 0.07-0.2 mm.

クッション体には、合成樹脂粒子１００重量部に対して、粉砕発泡体１０重量部〜４０重量部を充填していることが好ましい。合成樹脂粒子１００重量部に対して、粉砕発泡体が１０重量部未満では、クッション体のしっとり感が充分ではなく、合成樹脂粒子１００重量部に対して、粉砕発泡体が４０重量部を超えると、合成樹脂粒子の流動性が低下して触感も低下する。本実施例において、クッション体には、未発泡状態の発泡性ポリスチレン樹脂粒子１００重量部に対して、ポリウレタン樹脂を発泡させた発泡体を細かく粉砕した粉砕発泡体２０重量部を充填している。 The cushion body is preferably filled with 10 parts by weight to 40 parts by weight of a crushed foam relative to 100 parts by weight of the synthetic resin particles. When the amount of the crushed foam is less than 10 parts by weight with respect to 100 parts by weight of the synthetic resin particles, the moist feeling of the cushion body is not sufficient, and when the crushed foam exceeds 40 parts by weight with respect to 100 parts by weight of the synthetic resin particles. The fluidity of the synthetic resin particles is reduced, and the touch is also reduced. In the present example, the cushion body is filled with 20 parts by weight of a pulverized foam obtained by finely pulverizing a foam obtained by foaming a polyurethane resin, with respect to 100 parts by weight of foamable polystyrene resin particles in an unfoamed state.
