Description

  The present invention relates to a cushion material used widely such as bedding such as a futon or pillow, a cushion, a backrest of an automobile seat or a chair, a warm bed, a waist belt, a bandana, and the like, and a method for manufacturing the same.

  Conventionally, many types of elastic materials such as cotton and urethane foam have been used as cushion materials for futons and pillows. As such a cushioning material, there is one using a heel. For example, there is a technique for fitting and bonding the opening surfaces (cut end portions) of two scissors whose ends are cut to remove the internal scissors to form a single scissor that is close to a scissor shape ( For example, see Patent Document 1).

In the cushion material described in Patent Document 1, an elastic material (for example, cotton, feathers, lint, vinyl beads, styrofoam, etc.) is filled in the inside of the bag (internal space from which the bag is removed). The filling is changed depending on
JP-A-1-113006

  In the cushion material described in Patent Document 1, it is described that the heat storage effect is improved when the foam is filled with foamed polystyrene, cotton, or the like. Since the cotton is not fixed inside, the cotton may move in the bag and be biased with long-term use of the cushion material.

  In such a case, a space is partially generated in the bag, or the filling density of the cotton is partially reduced, so that the elasticity of the cushion material may be partially impaired or may not be restored while being recessed. Can happen. For this reason, there is a demand for a cushion material having higher quality and superior durability.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a highly durable cushion material that does not lose elasticity even when used for a long period of time, and a method for producing such a cushion material. It is said.

  In order to solve the above-mentioned problem, the cushion material of the present invention is separated from the cocoon glass into the cotton obtained from other cocoon glass inside the cocoon from which the contents of the cocoon after drying are extracted. It is characterized in that it is obtained by filling the cotton with the cercin obtained.

  According to this cushioning material, since the silk filled inside the cocoon (garbage) is attached with cercin, the stuffed cotton is not only firmly attached to the inner wall of the cocoon by cercin, The cotton fibers are firmly bonded to each other and hardened. Thereby, even if used for a long period of time, the cotton does not move inside the bag, and the original state where the cotton is uniformly packed inside the bag is maintained.

  In this cushion material, it is preferable that the filled cotton has a deodorizing / preserving material added thereto. Examples of the deodorizing / preserving material include ceramic powder, charcoal powder, and bamboo powder. Moreover, it is preferable that a film of cercin is formed on the surface of the bag after filling with cotton.

  Such a cushioning material may be used as it is, but may be used by connecting a plurality thereof. In this case, a through hole is formed in the cushion material, a connecting tool is passed through the through hole, and a plurality of cushion materials are connected by the connecting tool. For example, if it is more convenient to use elastic materials such as waist belts and bandanas, it is inconvenient even if there is no elastic material such as bedding, cushions, backrests, and warmths. If there is no string, a string made of thread, cloth, leather or the like may be used.

  Moreover, the manufacturing method of the cushioning material of the present invention forms a small hole at the end of the ridge after drying, extracts the contents of the ridge from the small hole, and from the other ridge glass inside this ridge It is characterized in that the obtained cotton is filled with the cotton with cercin obtained by separating from the straw.

  Also in this manufacturing method, it is preferable to add a deodorizing / preservative to the cotton before filling. Moreover, it is preferable to form a film of cercin on the surface of the bag after filling with cotton.

  According to the first and fifth aspects of the present invention, since the cotton does not move inside the bag even when used for a long time, the original state where the cotton is uniformly packed inside the bag is maintained, It is possible to provide a highly durable cushion material that does not lose elasticity even when used.

  According to the second and sixth aspects of the invention, the deodorization and antiseptic effects are enhanced, and the comfort and durability are further improved.

  According to the third and seventh aspects of the invention, since the surface of the cushion material, that is, the surface of the heel is solidified by the coating of cercin, not only the entire heel becomes stronger, but also the surface of the cushion material frays. No longer happens.

  Hereinafter, the present invention will be described in more detail with reference to embodiments.

  A cushioning material according to the embodiment is shown in FIG. (A) of FIG. 1 shows the expanded sectional view of a cushion material, (b) shows the expanded sectional view of the state which passed the coupling tool through the cushion material. A cushion material 1 shown in FIG. 1 (a) is filled with cotton 3 from a small hole 2b inside a bag 2 and the surface of the bag 2 (the entire surface of the outer shell 2a) is coated with cercin. 5 is formed. A cushion material 1 shown in FIG. 1 (b) is obtained by forming a through hole in the major axis direction in the cushion material 1 and inserting a connector (for example, a string) 10 through the through hole.

  The manufacturing method of such a cushioning material 1 is demonstrated with reference to FIGS. First, in FIG. 2 (a), the end portion of the well 2 that has been sufficiently dried is heated by, for example, a soldering iron 20, and the end portion has a diameter of about 6 mm (the tube 21 used to suck the next contents can be inserted). ) Of small holes 2b. The fibers around the small holes 2b adhere to each other with cercin (Nika), which is the composition of the ridge 2 during heating, so that the small holes 2b having a firm shape are formed. In addition, at the time of a heating, the contents, such as the basket 7 and its discharge thing, are still in the inside of the basket 2.

  Next, as shown in FIG. 2 (b), the suction tube 21 is inserted through the small hole 2b of the rod 2, and the vacuum pump (not shown) connected to the tube 21 is used to Aspirate the internal contents (eg 7). At this time, if the ridge 7 is too large and cannot be sucked as it is, the ridge 7 is crushed and made fine by the tip of the tube 21, and the debris 7a is sucked out. At the time of this suction, the inside of the basket 2 can be cleaned cleanly by injecting soap water, water, etc. through the tube 21 to suck the contents. The cocoon 2 that sucks the contents of the cocoon 7 and the like becomes galley.

  Next, as shown in FIG. 3 (a), for example, using a special nipper 22 having a thin tip as a tool, the cotton 3 is pushed into the inside of the bag 2 that has been cleaned from the inside through the small hole 2b. So as to fill. The filled cotton 3 is obtained by attaching cercin (Nika) obtained by separating from the cotton bran to the cotton obtained from the other glass.

  Here, in order to produce cocoon based on the cocoon, the cocoon glass is boiled in hot water at 80 to 100 ° C. for about 60 minutes to separate mushroom-like cercin (Nika) and fiber lumps. To do. One cocoon is filled with the cotton obtained by boiling the other 20 cocoons as described above. Even if the deodorizing / preserving material (ceramic powder, charcoal powder, bamboo powder, etc.) is added to the cotton 3 for the purpose of enhancing the deodorization and antiseptic effect and improving the comfort and durability when filling the cotton 3. Good.

  After filling, the cotton 3 is tightly packed inside the bag 2 [(b) of FIG. 3]. The true cotton 3 not only firmly adheres to the inner wall of the heel 2 by cercin, but also the fibers of the true cotton 3 firmly adhere to each other and harden. For this reason, even if it is used for a long time, the cotton 3 does not move inside the bag 2 and the original state where the cotton 3 is uniformly packed inside the bag 2 is maintained. Of course, the cotton 3 does not come out of the small hole 2b. Thereby, even if it is used for a long period of time, the cushioning material 1 with high durability can be provided without losing elasticity.

  The heel 2 filled with the cotton 3 may be used as a cushion material as it is, but more preferably, as shown in FIG. 4 (a), the entire surface of the heel 2 (ie, the outer shell 2a), The cercin 30 obtained as described above may be sprayed by, for example, the nozzle 23 to form the cercin coating 5 on the entire surface of the ridge 2 (see a partially enlarged sectional view of FIG. 4B). As a result, the surface of the cushion material 1, that is, the surface of the heel 2 is solidified by the cercin coating 5, so that not only the entire heel 2 becomes stronger, but also the surface of the cushion material 1 does not fray.

  The ridge 2 in a state in which the coating 5 of cercin is formed becomes the cushion material 1 shown in FIG. The cushion material 1 may be used as it is, but a plurality of the cushion materials 1 may be connected and used. The processing method in this case is shown in FIG. As shown in FIGS. 5A and 5B, a long-diameter through-hole 15 is formed in the heel 2 as the cushion material 1 by, for example, a drill 24. The heel 2 in a state where the coupling tool (for example, a string) 10 is passed through the through hole 15 becomes the cushion material 1 shown in FIG.

  The through hole 15 is not necessarily formed in the major axis direction, and may be formed in the minor axis direction or the oblique direction depending on the application.

  Also, the cross-sectional shape of the through-hole 15 does not need to be circular, but the properties of the cushion material 1 such as elasticity, stiffness (softness), heat retention, heat dissipation, and weight are adjusted according to the size of the through-hole 15. Is possible. That is, for example, assuming that the cross-sectional shape of the through-hole 15 is circular, in the case of the small-diameter through-hole 15a as shown in FIG. 6A, the thickness (maximum) from the surface of the flange 2 to the through-hole 15a (Thickness) Since t1 can be made large (because the gap by the through hole 15a is small), a large amount of filling of the cotton 3 inside the collar 2 can be secured, compared with the cushion material 1 when the through hole 15a is not formed, The above-mentioned properties without inferiority are maintained.

  On the other hand, in the case of the large-diameter through-hole 15b as shown in FIG. 6B, the thickness (maximum thickness) t2 from the surface of the flange 2 to the through-hole 15b becomes small (through-hole Since the gap due to the hole 15b is large), the filling amount of the cotton 3 inside the heel 2 is reduced, and the elasticity and heat retention are reduced compared to the cushion material 1 when the through hole 15b is not formed. Improve, soften and lighten.

  Accordingly, the size of the through-hole 15 is reduced in the case of an application that requires elasticity, rigidity, and heat retention, and conversely, in the case of an application that requires softness, heat dissipation, and lightness, The property as the cushioning material 1 can be adjusted by increasing the size.

  For example, a plurality of cushion materials 1 having through holes 15 are connected as shown in FIG. In (a) of FIG. 7, a plurality of cushion materials 1 are connected by a connecting tool 10. Of course, the plurality of cushion materials 1 may be connected in a straight line or may be connected in a bead shape. As described above, in the case where the connector 10 is used for stretchability such as a waist belt or a bandana, a rubber cord is used.

  In FIG. 7 (b), a plurality of cushion members 1 connected in a straight line with a connector 10 are arranged in parallel with another connector 11 and connected in a planar shape. For the connecting tools 10 and 11, for example, bedding, a cushion, a backrest, a warmer or the like, a string made of thread, cloth, leather, or the like is used for applications that do not have any inconvenience even if they are not stretchable.

  Thus, the cushion material 1 of this embodiment can be applied to a wide range of uses. In addition to the previous example, for example, one cushion material 1 may be attached to the tip of the rod and used for finger pressure. Or what connected the some cushioning material 1 to linear form can be used as a stepping tool, or it can be used as a roller of a massage instrument from the high durability, and can also be used for massages, such as a sole, a calf, and a thigh.

  Alternatively, taking advantage of the fact that wrinkles are a natural material that is gentle to the skin, it is also possible to use the cushion material 1 as a beauty device for stroking the skin such as the face.

  Further, as described above, when the size of the through-hole 15 is increased, the weight per one cushioning material 1 is lightened, so that the cushioning material 1 is connected in a planar shape as shown in FIG. Can be used as a material for futons to provide lighter futons. Of course, the weight of the futon can be freely adjusted by the size of the through hole 15.
