Abstract

The purpose of the present invention is to provide bedding that prevents air from leaking out immediately after air is introduced into the bedding. The bedding of the present embodiment comprises a hollow main body (21), a hollow suction portion (24) integrally extending from the main body (21) and having a suction port (25) at the front end portion, and a tubular portion (26) formed of a flexible material inside the suction portion (24). The tubular portion (26) extends toward the main body portion (21) and has an outflow port (27) for allowing air sucked from the suction port (25) to flow out toward the main body portion (21).

Claims (5)

  1. 1. A bedding, comprising: A hollow main body portion; a hollow suction part integrally extending from the main body part and having a suction port at a front end part, and A tubular part formed by a flexible material in the suction part, The tubular portion extends toward the main body portion and has an outflow port for allowing air sucked from the suction port to flow out toward the main body portion, The outer edges of the left and right sides of the cylindrical portion are welded together with the outer edges of the left and right sides of the suction portion from the rear end to the middle portion in the front-rear direction of the cylindrical portion, but are not welded to the suction portion from the middle portion to the front end, The middle part is provided with a welding part which is welded between the outer edges of the left and right sides of the suction part in a manner of being wider than other welding parts in the left and right direction, The tubular portion is contracted by the pressure of the air flowing out into the main body portion, the outflow port is blocked, and the tubular portion functions as a check valve, The tubular portion is wound toward the main body portion side together with the suction portion by winding the suction portion toward the main body portion side to seal the main body portion, The width of the suction part in the left-right direction is larger than that of the neck insertion part, The suction part has a core member disposed along the opening of the suction port, When the suction portion and the cylindrical portion serving as the check valve are wound together toward the main body portion side, the core member is wound around the core member.
  2. 2. The bedding of claim 1, wherein the bedding is a bedding, The outflow port is located near a boundary between the main body portion and the suction portion.
  3. 3. The bedding of claim 1, wherein the bedding is a bedding, The main body portion has a rear portion covering the user's neck from the rear side and a pair of side portions covering the user's neck from the left and right, surrounding the user's neck.
  4. 4. The bedding of claim 1, wherein the bedding is a bedding, The bedding comprises a cover body covering the main body part and the suction part, The cover is detachable with respect to the main body portion and the suction portion.
  5. 5. The bedding of claim 4, wherein the bedding is a bedding, The cover body has a main body cover portion covering the main body portion and a suction cover portion covering the suction portion in an integrated manner, The tubular portion is wound toward the main body cover portion by winding the suction cover portion toward the main body cover portion, and is wound toward the main body cover portion together with the suction cover portion and the suction portion, thereby sealing the main body portion.

Description

Bedding articles Technical Field The present invention relates to bedding. Background Conventionally, bedding for use by putting air into the interior is known. Patent document 1 discloses an air pillow including a bag body having an opening for sucking air, a sealing member for sealing the opening in the bag, and a cover bag having a receiving opening for receiving the bag body. The air pillow of patent document 1 is configured to be able to be worn on the neck of a user by placing air into the opening of the bag body and closing the opening, then winding the rear portion of the bag body toward the front portion of the bag body, and finally closing the storage opening with the fixing member of the bag body. Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 3184468 Disclosure of Invention Technical problem to be solved by the invention However, in the air pillow of patent document 1, there is a possibility that air leaks out from the opening of the bag body during a period from when air is put in through the opening of the bag body to when the opening is sealed. The present invention has been made in view of the above-described problems, and an object of the present invention is to suppress leakage of air immediately after air is introduced into the interior. Solution for solving the technical problems The present invention is characterized by comprising a hollow main body, a hollow suction portion integrally extending from the main body and having a suction port at a distal end portion, and a tubular portion formed of a flexible material in the suction portion, wherein the tubular portion extends toward the main body and has an outflow port for allowing air sucked from the suction port to flow out toward the main body, wherein the tubular portion is contracted by the pressure of the air flowing out into the main body, and the outflow port is blocked to function as a check valve, and wherein the tubular portion is wound toward the main body side by winding the suction portion toward the main body side together with the suction portion to seal the main body. ADVANTAGEOUS EFFECTS OF INVENTION According to the present invention, it is possible to suppress leakage of air immediately after the air is introduced into the interior.

Detailed Description Hereinafter, an embodiment of the bedding according to the present invention in the form of the neck pillow 100 will be described with reference to the drawings. The neck pillow 100 according to the present embodiment is configured to be able to be worn on the neck of a user by putting in air from a state where the air does not enter, and is configured to be able to be folded and stored compactly by exhausting the air. Fig. 1 is a perspective view showing the structure of the neck pillow 100 after air is introduced. Fig. 1 (a) is a perspective view of the neck pillow 100 from the upper side, and fig. 1 (b) is a perspective view of the neck pillow 100 from the lower side. In each of the drawings including fig. 1, for ease of explanation, upper, lower, front, rear, right, and left are appropriately illustrated with reference to a state in which the neck pillow 100 is worn on the neck of a user. The neck pillow 100 is substantially annular in plan view, and has a neck insertion portion 10 at the center through which a user's neck is inserted. The neck pillow 100 has an opening 11 on the front side, which is discontinuous in a part of an annular shape and can be opened to the left and right. The user inserts his/her own neck through the neck insertion portion 10 via the opening portion 11, and wears the neck pillow 100 on his/her neck. Fig. 2 is a view showing the structure of the neck pillow 100 in an expanded state before air is introduced. Fig. 2 (a) is a top view of the neck pillow 100, and fig. 2 (b) is a side view of the neck pillow 100. As shown in fig. 2 (a),
