Description

  The present invention relates to a stuffing material filled in a bag such as a pillow, cushion, or mat.

  Conventionally, for example, a stuffing material filled in a supporting bag body such as a pillow, a cushion, or a mat for supporting all or part of the human body has already been provided. Specifically, a molded article in which a natural material such as buckwheat husk, cotton, or feathers or a synthetic resin such as polyethylene, polypropylene, or polyurethane is formed into a cylinder or a spherical shape is well known.

For example, Patent Literature 1 proposes a cylindrical filling made of a molding material containing cellulose acetate, starch, CaCO ₃ or talc as a pillow filling. Patent Document 2 proposes a pillow in which countless granular foams having a particle diameter of about 3 to 15 mm mainly composed of glass powder are packed. Patent Document 3 proposes a stuffing material composed of a thin resin wall that forms a closed hollow portion, and the thin resin wall is made of a polyolefin-based resin or a polyester resin, and may further contain fibers. It is disclosed. Furthermore, a cushioning material including the stuffing material has been proposed, and a cushioning material for office, home, or automobile is exemplified. Patent Document 4 proposes a packed object that is divided into small chambers by partitions or sachets and filled with granular objects. Further, resin foam, resin beads, wood chips, bamboo chips, resin pipe cut products, granular fiber bodies, charcoal, grain beans, buckwheat, stones and plant seeds have been proposed as the granular objects, Examples of the stuffing object include mattresses, bed pads, mats, cushions or pillows.

  The bag body is generally provided with a filling port that can be opened and closed by a wire fastener or the like so that the manufacturer or individual user can fill the bag body with the filling material. .

  In addition, it is already known that the filling amount of the padding material is appropriately adjusted in order to appropriately support a support target such as a human body or the user's preference. For example, the amount of stuffing material can be reduced to reduce the tension generated on the surface of the bag body, and the bag can be softly wrapped around the user. Conversely, the amount of stuffing material can be increased to increase the repulsive force. It may be a bag body. In particular, in the case of pillows, the filling amount of the stuffing material may be appropriately adjusted in order to adjust the pillow height according to the body shape of the user.

  However, in the conventional configuration described above, since each stuffing material is generally small pieces and small grains in consideration of the feeling of use, when the stuffing material filled in the bag body is taken in and out, the stuffing material is mistaken. There was a problem that spilled out. Specifically, when the filling port is opened, the filling material already filled overflows, or when the filling material is added from the filling port to fill the desired amount of the filling material, It may spill out from the edge. In addition, in the case of the granular stuffing material, if the filling amount is insufficient, the stuffing material may flow toward the side when the support target is supported, so-called bottoming may occur, and the feeling of use may be impaired. there were. In particular, when bottoming occurs in the pillow, the feeling of use is significantly reduced. In addition, if the cushion or the like is held at an angle, the stuffing material in the inside flows to one side, causing a deviation, which may cause problems. Furthermore, in the conventional stuffing material, since it is granular as described above, the air permeability in the bag body deteriorates in the state of filling the bag body, and in terms of usability and maintenance management as a whole. There was a problem.

  Therefore, an object of the present invention is to provide a stuffing material that is difficult to spill out of the bag body when the stuffing material filled in the bag body is taken in and out, prevents bottoming, and ensures air permeability.

  The present invention is a stuffing material comprising a plurality of main members filled in a flexible bag capable of supporting an object to be supported, comprising a linear member connecting the plurality of main members, and a predetermined number of The stuffing material is characterized in that the main members are arranged in one longitudinal direction along the longitudinal direction of the linear members.

  A plurality of stuffing materials having such a configuration are prepared and used in a bag. Here, since the stuffing material according to the present invention is a daisy chain between the main members, when the filling amount of the main members is increased or decreased, a plurality of main members can be handled in a packed state. The workability is dramatically improved in the work of increasing or decreasing the amount. As described above, when the plurality of main members are connected by a single linear member, for example, the granular main member is prevented from spilling out at a stretch. In addition, when the number of main members is arranged in advance for a single linear member, for example, by specifying the approximate correlation between the number of stuffing materials and the thickness of the bag, There is an advantage that the number of padding materials to be filled in the bag can be easily grasped. Further, the above configuration makes it possible to limit the fluidity of the main member in the bag body by the linear member, and the padding material is compared with the conventional configuration in which only a large number of main members are used. In other words, it can be a bulky mass. For this reason, it becomes possible to give sufficient thickness (for example, pillow height from a floor surface) with respect to a bag body only by filling a small amount of main members compared with the past, and it is easy to ensure the thickness of a bag body. There is an advantage of becoming. Furthermore, the configuration according to the present invention prevents the main member from flowing excessively toward the side in the bag body by restricting the fluidity of the main member even when the support target is supported. So-called bottoming can be suitably prevented. In addition, since the stuffing material according to the present invention is a bulky structure as described above, a sufficient gap can be secured in the bag body even in a state where the support object is supported, and the air permeability in the bag body is good. can do.

  Further, it is desirable that the main body member is provided with a through hole, and the main body member is connected by inserting the linear member into the through hole.

  With such a configuration, there is an advantage that the main members can be easily connected to each other by the linear members while having a simple structure, and the manufacturing cost can be reduced as a whole.

  Moreover, it is preferable that the said linear member is made into cyclic | annular form by bundling both ends.

  By adopting such a configuration, the stuffing material having a plurality of main members is improved as a whole, and there is an advantage that handling properties are improved.

  Moreover, it is desirable that the linear member is made of an elastic material that can expand and contract along the connecting direction of the main body member.

  In such a configuration, since the linear member has elasticity in the longitudinal direction, it is possible to appropriately increase the fluidity of the main member in the bag body and to impart flexibility to the bag body. The feeling of use of the bag body can be further finely adjusted.

  The stuffing material of the present invention is advantageous in that workability at the time of adjusting the filling amount is improved without spilling out in the form of grains when the filling amount is adjusted. Moreover, the fluidity | liquidity of main body members can be suppressed, it can be made bulky as a stuffing material, and there exists an effect which can ensure desired thickness with a small amount of main body members compared with the past. Moreover, this invention can prevent bottoming and can ensure air permeability.

The pillow as a bag is shown, (a) is a top view, (b) is a front view. It is an external appearance perspective view which shows a stuffing material. It is explanatory drawing which shows the adjustment port periphery. It is the schematic of the filling material concerning another Example.

  Hereinafter, the example which materialized the stuffing material of the present invention is described in detail. In addition, this invention is not limited to the Example shown below, A design change is possible suitably.

  As shown in FIG. 1, a stuffing material 1 </ b> A according to the present invention (see FIG. 2) is filled in a pillow 50 whose support target is a human head and neck.

First, the shape of the pillow 50 will be described.
The pillow 50 is flexible and has a bag shape, and has a symmetrical shape in plan view when installed on the floor surface. Moreover, the polyester fiber which ensured air permeability is used for the front side surface 50a. On the other hand, cotton is used for the back side surface 50b in contact with the floor surface.

  In the center of the pillow 50, a small chamber portion 51 for supporting the user's back of the head and a small chamber portion 52 for supporting the neck portion are provided. Furthermore, the left and right sides of the small chamber portion 52 are provided with small chamber portions 53 for supporting the neck portion from the side, and the left and right sides of the small chamber portion 53 support the temporal region when turning over. A small chamber portion 54 is provided. Moreover, in the internal space of this pillow 50, each small chamber part 51-54 is partitioned off so that it may become each independent space.

  In addition, on the back side surface 50 b of the pillow 50, adjustment ports 51 a to 54 a are provided for the small chamber portions 51 to 54, respectively, in order to insert and remove the stuffing material 1 </ b> A. More specifically, each of the adjustment ports 51a to 54a is constituted by a wire fastener, is normally closed, and can be opened and closed at appropriate times. In addition, the vertical length of the pillow 50 in this embodiment is about 370 mm, the horizontal width is about 730 mm, and the thickness is about 2 to 60 mm.

  Next, the filling material 1A filled in the pillow 50 will be described in detail.

  As shown in FIG. 2, the stuffing material 1 </ b> A includes a cylindrical main member 10 having elasticity, and an inner space of the main member 10 is a through hole 10 a. Further, a linear member 20 made of a string made of stretchable polyurethane is inserted into the through hole 10a, and a plurality of the main members 10 are arranged along the longitudinal direction of the linear member 20. Are connected to each other. And the both ends of this linear member 20 are tied together, and this stuffing material 1A is made into a ring like a so-called bead.

  As the main member 10, for example, a cylindrical member having an outer diameter of about 4 mm, an inner diameter of about 3 mm, and a length of about 6 mm can be employed. For example, as the linear member 20, a string having an outer diameter of about 1 mm and a length of about 1 to 3 m can be employed.

  The main member 10 is preferably made of a material having elasticity, and examples thereof include elastomers, polyolefins such as polyethylene and polypropylene, synthetic rubber materials such as polyurethane and ABS resin, and natural rubber. Further, fiber materials may be mixed with them.

  The material of the linear member 20 is not particularly limited as long as it has a rigidity that is not cut during use, but in terms of productivity and strength, cotton yarn, hemp yarn, nylon fiber, urethane fiber, polyester fiber, acrylic fiber, Polyurethane fibers can be used.

  Next, an operation process for filling the small chamber portions 51 to 54 of the pillow 50 with the stuffing material 1A will be described. Each of the small chamber portions 51 to 54 may be filled with the stuffing material 1A uniformly, or stuffing materials 1B and 1C having other shapes as described later may be filled in place. It may be.

  For example, as shown in FIG. 3, the adjustment port 54a provided in the small chamber portion 54 is opened, and a predetermined number of filling materials 1A are filled. Here, even when the small granular main member 10 protrudes from the adjustment port 54a during the operation, the main member 10 is separated by itself because it is connected to the other main member 10 by the linear member 20. Never spill out to the outside. Moreover, since the stuffing material 1A is annular, it is excellent in handleability by being compactly packed as a whole. In addition, by determining the number of main members 10 arranged in advance for a single linear member 20, for example, an approximate correlation between the number of filling materials 1A and an appropriate amount of filling is roughly specified. This makes it possible to easily grasp the number of stuffing materials 1A to be filled. When manufacturing the stuffing material 1A, the main member 10 is formed into a member shape in which the through hole 10a passes through the center, so that the linear members 20 are easily inserted into the plurality of main members 10 one after another. Is possible.

  Furthermore, the stuffing material 1A can limit the fluidity of the main member 10 in the pillow 50 by the linear member 20, and the entire stuffing material 1A can be made into a bulky lump. It is possible to sufficiently secure the thickness of the pillow 50 (the height of the pillow from the floor surface) simply by filling a small amount of the main member 10 as compared with the above. In addition, when supporting the head or the like to be supported, the fluidity of the main body member 10 is limited so that the main body member 10 does not flow excessively toward the side in the pillow 50. So-called bottoming can be suitably prevented. Moreover, since the stuffing material 1A is a bulky structure as described above, a sufficient space can be secured in the pillow 50 even when the head is supported, and the air permeability in the pillow 50 is good. can do. Further, even if the pillow 50 is tilted, the main body member 10 that is the content is less likely to be biased.

  In addition, by configuring the linear member 20 with a string having elasticity in the longitudinal direction, the fluidity of the main member 10 in the pillow 50 can be appropriately increased, and the small chamber portion 54 The familiarity of the main member 10 is improved, and it is possible to give the small chamber portion 54 appropriate flexibility. Therefore, it is possible to ensure a good feeling of use (a sense of security, a sense of stability, and a suitable sleeping comfort) of the pillow 50 as before.

  In addition, when it is set as the structure described so far, for example, the manufacturer who sells the pillow sells only the stuffing material 1A, and makes the user himself / herself easily increase / decrease the stuffing material 1A. It becomes possible.

Other forms of main members 15 and 16 are also proposed.
For example, as shown in FIG. 4a, a solid spherical member may be provided with a through hole 15a to form the main member 15, and a linear member 20 may be inserted into the through hole 15a to form the stuffing material 1B.

  As shown in FIG. 4b, a hollow sphere member may be provided with a through hole 16a to form a main member 16, and a linear member 20 may be inserted into the through hole 16a to form a stuffing material 1C.

  Moreover, it replaces with the structure described so far, for example, the through-hole may be provided in the side wall of the main body member 10,15,16. Moreover, the linear member 20 does not need to be annular, and may be a string-like body. Further, the end of the linear member 20 and the main members 10, 15, 16 may be heat-welded to bond them together. Moreover, you may make it solidify the edge part of the linear member 20, and the main body members 10, 15, and 16 with an adhesive agent. Moreover, the structure which the some stuffing material 1A, 1B, 1C is connected suitably, and comprises the 2 or more linear member 20 may be sufficient. Moreover, it is good also as a structure by which the main members 10,15,16 from which a shape differs on the single linear member 20 were arranged. In addition, the number of the main members 10, 15, 16 arranged in the single stuffing material 1A, 1B, 1C can be changed as appropriate. The present invention does not positively exclude the use of non-stretchable linear members.

  Moreover, although the pillow 50 was demonstrated to the example in the said Example, it is not limited to the pillow 50, General bag bodies, such as a cushion and a mat | matte, are used objects.
