Description

  The present invention relates to a dried leaf-containing pillow filled with dried leaves and having a moisture absorption effect, a relaxation effect, and a resting sleep effect, and a dry leaf-containing insect repellent having aromaticity, antibacterial properties, air purification action, insect repellent effect and the like.

Herbs and other medicinal herbs and forest leaves contain a large number of fragrant essential oil components that alleviate stress and fatigue, stabilize the body, have a restful sleep effect, bactericidal action, and prevent insects such as mites. It has been clarified medically and physiologically that it has excellent effects such as air purification action, and many attempts have been made to use these ingredients for treatment of diseases and health promotion as aromatherapy. Has been done.
The reason why I feel refreshed in the forest baths that have been in the spotlight in recent years is because the phytoncide, an aromatic component emitted from the forest, is filled in the air. Since this fragrance component has an excellent effect on a good night's sleep, there are many proposals to use strawberry fragrances and herbal leaves with a fragrance component as pillow filling materials, and some of them are put to practical use. Has been.
However, the use of wood chips such as oak as a filler lacks cushioning properties, and there is a problem that the corners of the chips hit the surface during use, resulting in pain and lack of usability.
In order to solve these problems, for example, (Patent Document 1) states that “a piece of a tree that emits phytoncide is dried and packed in a bag made of a non-woven fabric having air permeability, and the bag is made of a cloth cover. An "sleep pillow" characterized by being worn inside is disclosed.
(Patent Document 2) states that “the artificially dried cocoon to a moisture content of 15% or less is cut to a thickness of 0.5 mm or less, further crushed, sorted to a size of 10 mm or less in both width and length, and filled. An eaves pillow used as a material is disclosed.
(Patent Document 3) discloses a “pillow containing sawdust”, wherein the padding of the pillow is sawdust.
(Patent Document 4) discloses a “filling suitable for a pillow, which is obtained by performing low-temperature rapid drying of leaves and red beans collected from a todomatsu that has been pulled down using a high-frequency vacuum dryer”. Yes.

However, the above conventional techniques have the following problems.
(1) (Patent Document 1) uses natural dried pieces of wood such as sawdust, so it is necessary to process the trees into pieces in advance, and it takes time to dry because it is naturally dried. , Had a problem of lack of productivity.
(2) In (Patent Document 2), it is necessary to cut the ridge to a thickness of 0.5 mm or less, crush it further, and sort it into a size of 10 mm or less in both width and length. In addition, it took time for sorting and the problem of lack of productivity.
(3) (Patent Document 3) has a problem of lack of productivity because the sawdust is used. In addition, it is necessary to place a bag filled with rattan round beads on the surface of the pillow in order to improve heat absorption and hygroscopicity and relieve pain during use, resulting in low cost and low productivity. Was.
(4) (Patent Document 4) uses a tree leaf collected from a fallen Todomatsu, but it is a phytoncide that is an active ingredient in a dead tree leaf or a tree leaf that has been pulled down and soaked in rain water or the like. The content of is low, and there is a problem of lack of practicality due to lack of aroma, antibacterial and insect repellent effects, lack of relaxation effect and sleep rest effect by the action of forest bath.
(5) Even though the fragrance of the original forest bath is emitted from the leaves of the tree, not from the trunk of the tree, there is no pillow or fragrance that effectively uses the leaves, and there is a problem of lack of practicality and functionality. Was.

  The present invention solves the above-mentioned conventional problems, and by filling dry leaves obtained by drying low-temperature dried leaves having a large amount of aromatic components compared to trees and herbs, there is a cushioning property, and the aromaticity is increased due to the forest bath effect. By providing pillows with dry leaves that are excellent in relaxation and sleep, effectively use leaves, save resources, and are low in cost, and by drying the leaves at low temperatures, it is possible to prevent the deterioration and transpiration of aromatic components. The purpose of the present invention is to provide an insect repellent containing dried leaves, which has excellent properties, antibacterial properties, air purification action and insect repellent effect.
