Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.
The pillow 10 in the present invention is a strip-shaped soft polyurethane foam content member 11 that is profiled on at least one of the front and back surfaces, and a bag-like bag member 12 that covers the content member 11. A plurality of shape holding members 13 are provided at both ends in the longitudinal direction and both ends in the width direction of the bag member 12 to hold the shape of the pillow 10. When used as the pillow 10, the shape holding member 13 The pillows 10, 10 </ b> A, and 10 </ b> B can have different outer shapes, and can be in an unfolded state together with the contents member 11 covered with the bag member 12 during washing and subsequent drying.

The content member 11 constituting the pillow 10 is made of a strip-like flexible polyurethane foam made non-filmy, and profile processing 11a is applied to at least one of the front and back surfaces. In addition, the profile process should just be given to the location corresponded to a bending part, and may be given to one whole surface of front and back, or the whole surface of both front and back.
For example, as shown in FIG. 4, it is preferable that irregularities are formed in a zigzag pattern on the entire surface because the head is positioned on the surface on which the profile processing 11 a is performed. Thereby, the feeling of bottoming of a pillow can be eased.

The content member 11 of the flexible polyurethane foam has a density and hardness selected according to the user's preference, and can be used as a pillow. For example, the density is 20 kg / m 3 or more and the hardness is 40% compressed. A soft polyurethane foam having a film thickness of 60 N or more is used.
Here, the non-film-formed flexible polyurethane foam is obtained by removing a thin film from cells (bubbles) to make only a skeleton. As a method for removing the cell film, for example, alkali treatment, explosion treatment, or other heat treatment is employed.
Moreover, as a dimension of the strip | belt-plate-shaped content member 11, although it changes also with main outer shapes used as a pillow mentioned later, it becomes the range whose width is 400-600 mm, length is 500-1200 mm, and thickness is 20-50 mm. What should I do? If it does so, the external shape at the time of bending and using it as a pillow will be the range of 400-600 mm in width, 250-400 mm in length, and the thickness in 40-200 mm, and it is made the outline of the pillow currently used normally. it can.
Furthermore, it is preferable that 20% or more of the thickness of the content member 11 is profile-processed, so that it is easy to bend and the uncomfortable feeling at the bent portion can be eliminated. For example, as the content member 11, a member having a thickness of 35 mm, a strip-like profile processing height of 10/35 mm (minimum thickness 10 mm, maximum thickness 35 mm), a width of 540 mm, and a length of 760 mm is used.

  In addition, the non-film-formed flexible polyurethane foam used as the contents member 11 includes a non-film-formed low-resilience polyurethane foam, which can support the head uniformly and can be a pillow that is more comfortable to sleep. . The impact resilience of the low resilience polyurethane foam is measured by a method according to JIS K 6400-3, and preferably 1 to 20%.

  The bag member 12 provided so as to cover the content member 11 is, for example, as shown in each of FIGS. 1 to 3, in order to prevent direct contamination of the content member 11 constituting the pillow and to contact the head. In addition to providing a soft feeling at the time, the outer shape of the pillow is determined in cooperation with the shape holding member 13.

  The bag member 12 is preferably made of an easy-drying material such as a mesh fabric or cotton cloth so that the pillow can be easily dried after washing and soft when used as a pillow. For example, a 100% polyester mesh fabric is used. It is done.

  The bag member 12 is sized to accommodate the contents member 11, and has the dimensions of the above-described band-shaped body (profile processing height is 10/35 mm, width is 540 mm, length is 760 mm), for example, A polyester mesh fabric having a length of 800 mm and a width of 580 mm is sewed into a bag shape so that the content member 11 can be inserted with one side of the width being one end in the longitudinal direction as an opening. Close the part by sewing. In addition, you may make it close by providing a fastener in an opening part, and it becomes possible to isolate | separate easily the content member 11 and the bag member 12, and to wash or to dry.

After covering the belt-plate-shaped contents member 11 with such a bag member 12 and closing the opening by sewing, the contents member 11 and the bag member 12 may be sewn together. The portion to be sewn may be a portion where the contents member 11 and the bag member 12 do not shift when folded, and in particular, if the folded portion is sewn, it becomes easier to bend and keeps the outer shape as a pillow. This is preferable. For example, in order to be able to maintain the outer shape as a pillow, seams 14 and 14 having a certain length are put in the center portion in the width direction at two quarters of the length from both ends in the longitudinal direction. The seams 14 and 14 having a length of, for example, about 350 mm (the total width of the contents member is 540 mm) are inserted and fixed to each other.
By fixing the contents member 11 and the bag member 12 with the seams 14 and 14 as described above, the width of the sewing stopper is very small compared to the bag-like section and the like, so that it does not protrude sharply and is used as a pillow. It is possible to prevent deterioration of the sleeping comfort due to contact with the neck at the time.

Such a bag member 12 is provided with a plurality of shape holding members 13 for holding the outer shape as a pillow.
In this pillow, three different pillows 10, 10 </ b> A, 10 </ b> B shown in FIG. 1 to FIG. 3 can be made by changing the outer shape, and both longitudinal ends of the contents member 11 covered with the bag member 12 are arranged. A pillow 10 in a double-folded state (see FIG. 1) that is bent toward the center, a pillow 10A in a three-folded state (see FIG. 2) that is folded in two places and overlapped three times, and a rounded state wound from one end (FIG. 3) The shape holding member 13 is arranged at a position that can be held by the pillow 10B.
Here, the arrangement of the shape holding members 13, 13A, and 13B will be described separately when necessary to hold the three outer shapes, but the actual bag member 12 has a shape holding that can handle all cases. The members 13, 13 </ b> A, and 13 </ b> B may be provided on one bag member 12, or a shape holding member for holding one to a plurality of outer shapes may be provided as necessary.

  First, in the pillow 10 that is folded in a folded state in which both ends in the longitudinal direction are folded toward the center together with the contents member 11 covered with the bag member 12, both ends in the longitudinal direction of the bag member 11 are shown in FIG. A loop in which a string 13a having a length capable of bowing is attached to both ends and the center of each of the short sides, and a string in which the string 13a can be passed through the central part of the long side which is both ends in the width direction. 13b is provided.

Therefore, in this pillow 10, the lengthwise both ends of the contents member 11 covered with the bag member 12 are folded toward the center to be folded in two, and then the cords 13 a on both short sides of the bag member 12 are arranged. One of 13a is tied through the loop 13b, and the cords 13a, 13a at the center of the short side are used as a bow. Thereby, it can be set as the pillow 10 of a folded state.
Moreover, in this pillow 10, when it wash | cleans, it can be made into an unfolded state by unraveling the tied strings 13a and 13a, and it makes it easy to wash by making it into a single strip. , Making it easy to dry.
Furthermore, the bent portion in the case of the pillow 10 has a smooth curve, and does not protrude sharply as compared with the case where a bag-like section is provided, thereby preventing the sleeping comfort from being deteriorated due to contact with the neck or the like when used as a pillow. Can be made into a comfortable pillow.

  Next, when it is set as the pillow 10A which makes height higher than the pillow 10, as shown in FIG. 2, it folds | folds in two places with the content member 11 covered with the bag member 12, and is folded in three. As the shape-retaining member 13A, a string 13Aa having a length capable of bowing is attached to two positions on both ends of the short side that is both ends in the longitudinal direction of the bag member 11, and both end portions in the width direction The string 13Ab is provided at the position of three equal long sides.

Therefore, in this pillow 10A, after the three-folded state in which the contents member 11 covered with the bag member 12 is folded at two locations and overlapped in a triple manner, the string 13Aa at both ends of the short side of the bag member 12 and the side end portions The distant string 13Ab is a bow. Thereby, it can be set as the pillow 10A of a trifold state.
Moreover, in this pillow 10A, when washing, it can be made into an unfolded state by unraveling the tied strings 13Aa and 13Ab. , Making it easy to dry.
Furthermore, even in the case of the pillow 10A, the bent portion has a smooth curve, and does not protrude sharply as compared with the case where a bag-like section is provided, and prevents the sleeping comfort from being deteriorated due to contact with the neck or the like when used as a pillow. Can be made into a comfortable pillow.

  Next, when the pillow 10B is made higher than the two-folded pillow 10 and the three-folded pillow 10A, as shown in FIG. The shape holding member 13 </ b> B has a string 13 </ b> Ba having a length capable of bowing at two locations on both ends of the short side that is both ends in the longitudinal direction of the bag member 11.

Therefore, in this pillow 10B, after making it the round state wound from one end part together with the contents member 11 covered with the bag member 12, the string 13Ba at both ends of the short side of the bag member 12 and the string 13Ba at both ends of the other short side And each bow. Thereby, it can be set as the pillow 10B of the round state wound from the one end part.
Moreover, in this pillow 10B, when washing, it can be made into an unfolded state by unraveling the tied cords 13Ba and 13Ba, and by making it a single band plate shape, washing is facilitated. , Making it easy to dry.
Furthermore, even in the case of the pillow 10B, the rounded portion has a smooth curve and does not protrude sharply as compared with the case where a bag-shaped section or the like is provided, thereby preventing a deterioration in sleeping comfort due to contact with the neck or the like when used as a pillow. Can be a comfortable pillow.

In this pillow 10, the shape holding members 13, 13 </ b> A, 13 </ b> B can be easily formed on the pillows 10, 10 </ b> A, 10 </ b> B having different outer shapes by providing the shape holding members 13, 13 </ b> A, 13 </ b> B in one bag member 12. In addition, it can be easily performed without preparing a content member for height adjustment or taking out the content member.
Further, in this pillow 10, profile processing is applied to at least one of the front and back surfaces as the contents member 11, so that a pillow having a different outer shape is formed by bending using the unevenness due to profile processing of the contents member. It can be made into a pillow that does not feel strange even if the bent part has an acute angle, does not protrude thinly, and does not feel strange even if it comes into contact with the neck.
Furthermore, in this pillow 10, since the non-film-formed flexible polyurethane foam is used as the contents member 11, and profile processing is applied to at least one of the front and back surfaces, the unevenness due to the non-film formation and profile processing of the contents member is utilized. Thus, air permeability can be ensured, and drying after washing can be performed in a short time.

  In said embodiment, when using as the pillow 10,10A, 10B, it demonstrated as if the bag member 12 was used as an outer surface, However, Like a normal pillow, it seems to wind and use a pillow cover. And a general pillow cover of 430 mm × 630 mm can be used. Also, with the pillow cover, it is possible to wash only the pillow cover against normal dirt.

  In the above embodiment, a string or a loop has been described as an example of the shape holding member. However, the shape holding member is not limited to this, and any shape can be used as long as it can hold the shape when used as the pillow 10, 10A, 10B. Another stop can be used.
