Abstract

(57) [Abstract] [Purpose] To improve the structure of the stuff material for pillows made of plastic so as to eliminate the deformation and lack of elasticity during use. At the same time, prevent annoying noises. [Structure] The staff member 1 is formed of a spherical shell having an opening 3 in a peripheral wall. [Effect] In the use state, the staff members 1 are adjacent to each other via the spherical surface, so that they become slippery. The spherical shell 2 can be deformed by an external force from all directions. Since the staff members 1 are adjacent to each other with no extra gap and are easily slippery with respect to each other, there is no "sharpness" sound.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The invention relates to fillings for pillows, especially plastic molded staff material.

[0002]

[Prior art]

 As pillow fillings, buckwheat shells, fir shells, panyas, feathers, etc. are known, and in recent years, plastic-molded staff materials are often used (literature scandal). This stuffing material is made by extruding a tube having a diameter of about 6 mm and cutting it into a short tubular shape. A large number of the stuffing materials are filled in an inner bag to form a pillow. In many cases, the stuff is filled with enough space to allow the inner bag to flow.

[0003]

[Problems to be solved by the device]

 Compared with stuff materials such as feathers and foamed rubber, the short-tube stuff material molded with plastic has a large porosity, is highly breathable, and is easy to radiate heat. However, it lacks in softness and is as easy to use as a pillow filled with buckwheat shells or red beans. The short tubular staff member is made of soft plastic and can elastically deform itself. However, because it is a short cylinder, the direction of deformation is limited to the radial direction, and when the inner bag is filled, the postures of the individual staff members are different. This is because it cannot exhibit.

The cylindrical staff member also has a direction in slipperiness. When the circumferential walls are in contact with each other, they slip and change their positions and change their postures, but in other states it is difficult to displace them. Therefore, when the person rolls over, the surface of the pillow may remain dented, and the shape of the pillow filled with buckwheat shells lacks stability. When used, the individual staff members come into contact with each other, producing annoying noise, which is disadvantageous in that it prevents sleep. The staff material is made as small as possible to avoid the feeling of foreign matter during use. Therefore, the weight of the staff material per fixed volume is large, and it becomes heavy especially when a large pillow is formed.

The purpose of the present invention is to change the structure of the staff member to reduce the peculiarities of slipperiness and elastic deformability to a level where the peculiarity can be neglected, and to maintain proper elasticity without deforming during use. It is to provide a staff member for a pillow that can be exhibited, is light, and sufficiently suppresses the generation of annoying noise.

[0006]

[Means for Solving the Problems]

 In this invention, a plastic-made staff member 1 for a pillow 6 is formed by a spherical shell 2 having an opening 3 in a peripheral wall. Preferably, the spherical shell 2 is provided with a pair of openings 3 in parallel.

[0007]

[Action]

 In a state in which the group of staff members 1 is filled in the inner bag 4, the individual staff members 1 are brought into contact with each other by the spherical shells 2. Therefore, the adjacent staff members 1 can easily slide their positions and change their postures by sliding on each other with almost no directionality. Since the ball shell 2 can be elastically deformed in response to external forces from all directions, the softness and firmness of the entire pillow can be freely changed by changing the thickness and the ball diameter of the ball shell 2. The staff members 1 composed of the spherical shell 2 can be adjacent to each other without creating an unnecessary gap. Moreover, the adjacent staff members 1 can slide on each other to smoothly change positions and change postures. Therefore, abnormal noises such as a “creeping” sound are less likely to occur due to rolling over. . When the volume of the space occupied by the spherical shell and the cylindrical body is constant, if the wall thickness is the same, the weight of the spherical shell can be reduced and the surface area can be increased.

[0008]

[Effect of device]

 In this invention, the staff member 1 is formed of a spherical shell having an opening 3 in the peripheral wall, and it eliminates the occurrence of the respective directions of the sliding direction and the deformation direction, and the adjacent staff members 1 are unnecessary. It is designed so that they can be adjacent to each other in a slippery condition without any gaps. Therefore, when the pillow 6 is formed by using the staff member 1 of the present invention, it is possible to exhibit appropriate elasticity at the same time while preventing the pillow surface from being deformed such as being dented by turning over and so on. A pillow with excellent usability that can exhibit moderate softness at the same time can be obtained. It is possible to sufficiently suppress the generation of annoying noise due to collisions or friction between the staff members 1 and promote sleep. The stuff material 1 can be made lighter than the conventional stuff material having a cylindrical body, and the weight can be reduced even when a large pillow is formed.

【Example】

 1 to 2, the staff member 1 is made of soft polyethylene and is formed into a spherical shell as a whole, and a pair of openings 3 are formed in parallel with each other on the peripheral wall of the spherical shell 2. It becomes. The outer diameter D of the spherical shell wall 2 was 11.5 mm, the opening diameter d was 5.5 mm, and the wall thickness t was 0.5 mm. The stuff material 1 is formed by using the tube body extruded from the molding machine as a pre-stage material, and after introducing the tube body into the mold, it is formed into a spherical shell shape by applying a vacuum pressure in the mold. , Obtained by cutting the individual spherical shells 2.

The staff member 1 obtained as described above is filled in a middle bag 4 as shown in FIG. 3, and a bag cover 5 is put on the outer surface of the inner bag 4 to form a pillow 6. The inner bag 4 is made of cloth or net material.

In the above-mentioned embodiment, the pair of openings 3 are provided in parallel at two positions of the spherical shell 2, but it is not necessary. As shown in FIG. 4a, the opening 3 can be formed in only one place. Furthermore, as shown in FIG. 4b, three or more openings 3 can be formed in the spherical shell 2.

In addition to the above, when a plurality of openings 3 are formed, the opening diameters may be different.
