[0001] The present invention relates to an infant pillow.

[0002] In infants immediately after breastfeeding, "regurgitation" often occurs, where breast milk or infant formula drunk into the stomach flows back from the stomach through the esophagus into the oral cavity. Infants with underdeveloped respiratory organs, esophagus, etc. may suffocate because they cannot expel breast milk or infant formula that has flowed back into the oral cavity or nasal cavity due to regurgitation. Therefore, infant pillows that suppress infant regurgitation are known.

[0003] Patent Document 1 discloses an infant pillow whose shape when viewed from the side is formed in a triangular shape. The upper surface on which the infant is placed in the infant pillow is inclined at an angle within the range of 5° to 20° with respect to the bedding surface. Therefore, the infant pillow holds the upper body of the infant inclined within the range of 5° to 20° with respect to the bedding surface. By inclining the infant in this way, the occurrence of regurgitation can be suppressed.

[0004] Utility Model Registration No. 3104422

[0005] The infant pillow described in Patent Document 1 is composed of a polyurethane cushion, which is a soft material, to hold the infant in an inclined position. The infant placed on the infant pillow is held in a posture where the upper body is raised at an angle within the range of 5° to 20° with respect to the bedding surface due to the inclination of the upper surface. At this time, the head of the infant is held by the cushion.

[0006] The polyurethane constituting the infant pillow described in Patent Document 1 has high flexibility and excellent shock absorption properties, so it is widely used as a constituent material for cushions and the like. However, polyurethane has lower thermal conductivity and air permeability compared to other resin materials, so it is difficult to release heat, moisture, etc. to the outside. Therefore, in the pillow described in Claim 1 using polyurethane as a constituent material, there was a problem that heat, moisture, etc. accumulated in the head, back, etc. of the infant, and the comfort decreased as the usage time increased.

[0007] An object of the present invention is to provide an infant pillow that can suppress infant regurgitation while maintaining the comfort of the infant.

[0008] The inventors investigated an infant pillow that could suppress spitting up in infants while maintaining the infant's comfort. After diligent research, the inventors came up with the following configuration.

[0009] An embodiment of the present invention provides an infant pillow comprising: a head rest portion for supporting the infant's head; a shoulder rest portion connected to the head rest portion and supporting at least the infant's shoulders; and a support portion that supports at least one of the head rest portion or the shoulder rest portion relative to the bed surface on which the infant pillow is placed. The head rest portion and the shoulder rest portion are made of a plate-like member made of metal or resin having a plurality of through holes, and are inclined such that the height from the bed surface increases from the shoulder rest portion toward the head rest portion, and are supported by the support portion at a distance from the bed surface such that a space for ventilation is formed between them and the bed surface.

[0010] In the above configuration, the head rest and shoulder rest portions of the infant pillow are made of plate-like members made of metal or resin having multiple through holes. Furthermore, the head rest and shoulder rest portions are raised from the bedding surface by a support portion so that the head rest portion is higher than the shoulder rest portion. As a result, the head rest and shoulder rest portions dissipate heat, moisture, sweat, etc. released from the infant's body from the bedding surface side through the properties of the mesh and the multiple through holes. Therefore, the thermal conductivity and breathability of the infant pillow are higher than those of a pillow made of a soft material such as polyurethane and placed in close contact with the bedding surface. In addition, the infant pillow holds the infant's head at a position higher than the infant's shoulders and abdomen. This makes it possible to suppress spitting up while maintaining the infant's comfort.

[0011] From another perspective, the infant pillow of the present invention preferably includes the following configuration: The head rest and the shoulder rest are made of a mesh-like material.

[0012] In the above configuration, the head rest and shoulder rest, which are made of a mesh member made of metal or resin, have higher thermal conductivity and breathability compared to polyurethane and the like. Furthermore, since the mesh member has multiple meshes which are through holes, the breathability can be improved by increasing the porosity, which is the ratio of the area of ​​through holes per unit area. In addition, since the mesh member is made by weaving together multiple members, it has elasticity due to the movement and bending of the multiple members while maintaining the overall shape. As a result, it is possible to suppress spitting up by the infant while maintaining the infant's comfort.

[0013] From another perspective, the infant pillow of the present invention preferably includes the following configuration: The support portion is configured to allow the inclination angle of the head rest portion and the shoulder rest portion with respect to the sleeping surface to be changed.

[0014] According to the above configuration, the infant pillow can adjust the angles of the head rest and shoulder rest relative to the sleeping surface according to the infant's age, body shape, and degree of regurgitation. Therefore, the infant pillow can maintain a posture suitable for the infant's condition while holding the infant's head at a position higher than the infant's shoulders and abdomen. This makes it possible to suppress regurgitation while maintaining the infant's comfort.

[0015] From another perspective, the infant pillow of the present invention preferably includes the following configuration: The head rest portion is curved toward the sleeping surface and has a concave surface on which the back of the infant's head can be positioned.

[0016] In the above configuration, the head rest holds the back of the infant's head with a concave curved surface that curves toward the bedding surface. Therefore, the head rest prevents the infant from sliding or rolling off due to the inclination of the infant pillow. Furthermore, the head rest can maintain a natural supine posture while holding the infant's head higher than the infant's abdomen. Moreover, since the head rest holds the back of the infant's head with a concave curved surface, the weight of the infant's head does not concentrate on the part of the back of the infant's head that is closest to the bedding surface. Therefore, the head rest can suppress deformation of the back of the infant's head with the concave curved surface. This makes it possible to suppress spitting up by the infant while maintaining the infant's comfort.

[0017] From another perspective, the infant pillow of the present invention preferably includes the following configuration: The shoulder rest portion is inclined with respect to the shoulder rest portion such that, when viewed in the width direction, a virtual plane including the shoulder rest portion's shoulder rest surface is located between the portion of the concave curved surface closest to the sleeping surface and the upper edge of the concave curved surface.

[0018] In the above configuration, the head rest can be inclined relative to the shoulder rest surface to form a concave curved surface with a diameter and depth capable of holding the back of the infant's head in the same positional relationship as the infant's head relative to its back in an upright position. The concave curved surface holds the head of an infant in a supine position at the same position and angle as the head of an infant in an upright position relative to its upper body. This makes it possible to suppress spitting up while maintaining the infant's comfort.

[0025] Below, an infant pillow 1, which is Embodiment 1 of the infant pillow according to the present invention, will be described with reference to the drawings. In each figure, the same parts are denoted by the same reference numerals, and the description of the same parts will not be repeated. The dimensions of the components in each figure do not faithfully represent the dimensions of the actual components or the dimensional ratios of each component.

[0026] <Embodiment 1> An infant pillow 1 according to Embodiment 1 of the present invention will be described with reference to Figures 1 to 4. Figure 1 is a perspective view of the infant pillow 1 in Embodiment 1 of the present invention. Figure 2 is a top view of the infant pillow 1. Figure 3 is a side view of the infant pillow 1. Figure 4 is a side view showing an infant B lying supine on the infant pillow 1. In the following embodiment, the left-right direction of the head of the infant B placed on the infant pillow 1 is defined as the lateral direction of the infant pillow 1, the direction from the head to the shoulders of the infant B is defined as the vertical direction, and the direction perpendicular to the sleeping surface G on which the infant B and the infant pillow 1 are placed in the futon, bed, etc., is defined as the height direction.

[0027] As shown in Figures 1 to 3, the infant pillow 1 is a pillow intended for infants B aged 0 to 18 months. The infant pillow 1 has a head rest 2, a shoulder rest 3, a support 6, a cushion 7, and a cover 8.

[0028] As shown in Figures 1 and 2, the head rest 2 is the part on which the head of infant B is rested. The head rest 2 is a mesh member formed by weaving metal wires. In plan view, the head rest 2 has a frame 4 that is roughly rectangular and a mesh 5, for example made of iron, stretched over the frame 4. The head rest 2 is composed of a part of the frame 4 and a part of the mesh 5. The head rest 2 is constructed in a plate shape. The head rest 2 has a plurality of through holes 5a, which are the mesh openings of the mesh 5.

[0029] The shoulder support section 3 is the part that supports the shoulders and part of the chest of infant B. The shoulder support section 3 is a mesh member formed by, for example, weaving together iron wire. In plan view, the shoulder support section 3 has a frame 4 that is roughly rectangular and an iron mesh 5 stretched over the frame 4. The shoulder support section 3 is composed of a part of the frame 4 and a part of the mesh 5. The head support section 2 is constructed in a plate shape. The shoulder support section 3 has a plurality of through holes 5a that are the mesh of the mesh 5. The shoulder support section 3 is located adjacent to the head support section 2 in the vertical direction.

[0030] Thus, the head rest 2 and the shoulder rest 3 are constructed from the same frame 4 and net 5. In other words, the head rest 2 is located on one vertical portion of the net 5 stretched over the frame 4, and the shoulder rest 3 is located on the other vertical portion. The head rest 2 and the shoulder rest 3 are formed as a single unit.

[0031] As shown in Figures 1 to 3, the support portion 6 lifts the head rest portion 2 and the shoulder rest portion 3 from the bed surface G. The support portion 6 is connected to one end of the head rest portion 2 on the head side in the longitudinal direction. The support portion 6 has a pipe-shaped contact portion 6a that contacts the bed surface G, and connecting portions 6b that extend in the height direction from both ends of the contact portion 6a. The connecting portions 6b are connected to the end of the head rest portion 2.

[0032] As shown in Figure 3, the cushion 7 is a cushioning member that disperses the impact on infant B and the reaction force from the head rest 2 and shoulder rest 3. The cushion 7 is configured to cover the head rest surface 2a of the head rest 2 and the shoulder rest surface 3a of the shoulder rest 3. The cushion 7 is made of, for example, a highly breathable honeycomb structure cushioning material. The cushion 7 is placed on the head rest surface 2a and the shoulder rest surface 3a. In other words, the cushion 7 is located between infant B and the head rest 2 and shoulder rest 3.

[0033] The cover 8 covers the head rest 2, the shoulder rest 3, and the cushion 7. The cover 8 is constructed in a bag-like shape. The cover 8 is made of pile fabric. The cover 8 is configured to accommodate the head rest 2, the shoulder rest 3, and the cushion 7 inside.

[0034] As shown in Figure 4, the infant B is placed on the infant pillow 1 via a cushion 7 and a cover 8, with the infant B resting on the head rest 2 and shoulder rest 3. The head of the infant B is placed on the head rest 2. The shoulder rest 3 is placed on the shoulder rest of the infant B's shoulders and chest. The infant pillow 1 holds the infant B's head at a position higher than the infant B's shoulders and abdomen. The infant pillow 1 also holds the infant B's head and shoulders at a position separated from the sleeping surface G. Therefore, the infant pillow 1 creates a space between the head rest 2 and shoulder rest 3 and the sleeping surface G through which air can flow.

[0035] Heat and sweat emitted from infant B's head and back pass through the cushion 7, head rest 2, shoulder rest 3, and cover 8, and are discharged from the space between the head rest 2 and shoulder rest 3 and the bedding surface G (see arrow). Therefore, the thermal conductivity and breathability of the infant pillow 1 are higher than those of a pillow made of a soft material such as polyurethane and placed in close contact with the bedding surface G. This makes it possible to suppress spitting up by infant B while maintaining infant B's comfort.

[0036] <Embodiment 2> An infant pillow 1A, which is an embodiment 2 of the infant pillow of the present invention, will be described with reference to Figures 5 to 8. Figure 5 is a perspective view of the infant pillow 1A in embodiment 2 of the present invention. Figure 6 is a top view of the infant pillow. Figure 7 is a side view of the infant pillow 1A. Figure 8 is a side view showing an infant B lying supine on the infant pillow 1A. In the following, components similar to those in the above embodiment will be denoted by the same reference numerals and their descriptions will be omitted, and only components that differ from the above embodiment will be described.

[0037] As shown in Figures 5 to 7, the infant pillow 1A has a head rest 9, a shoulder rest 3, a support 6, a cushion 11, and a cover 8.

[0038] As shown in Figures 5 and 6, the head rest 9 is the part on which the head of infant B is rested. The head rest 9 is a mesh member formed, for example, by weaving together iron wire. The head rest 9 has a frame 4 that is roughly rectangular in plan view and an iron mesh 10 stretched over the frame 4. The head rest 9 is composed of a part of the frame 4 and a part of the mesh 10. The head rest 9 is constructed in a plate shape. The head rest 9 has a plurality of through holes 10a that are meshes of the mesh 10.

[0039] The head rest section 9 has a concave curved surface 9b projecting toward the bed surface G at approximately the center of the mesh 10 (the mesh 10 on the concave curved surface 9b is omitted). The concave curved surface 9b supports the back of the head of the infant B in a supine position. The concave curved surface 9b is composed of a part of a sphere. When viewed in a direction perpendicular to the head rest surface 9a of the head rest section 9, the concave curved surface 9b has a circular outer edge. In this way, the concave curved surface 9b is configured to cover the back of the head of the infant B.

[0040] As shown in Figures 7 and 8, the head rest 9 is inclined with respect to the shoulder rest surface 3a so that it forms a concave curved surface 9b with a diameter and depth capable of holding the back of the infant B's head in the same positional relationship as the infant B's head in an upright position. The portion T of the concave curved surface 9b closest to the bed surface G is located on the bed surface G side of the virtual plane P that includes the shoulder rest surface 3a of the shoulder rest 3 (see Figure 8). The concave curved surface 9b holds the head of the infant B in a supine position at the same position and angle of the head relative to the upper body of the infant B in an upright position.

[0041] The cushion 11 is a buffer member for the infant B. The cushion 11 is configured to cover the head placement surface 9a of the head placement portion 9 and the shoulder placement surface 3a of the shoulder placement portion 3. The cushion 11 is constituted by, for example, a highly breathable honeycomb-structured cushioning material. The cushion 11 is placed on the head placement surface 9a of the head placement portion 9 and the shoulder placement surface 3a of the shoulder placement portion 3. In the cushion 11, the head buffer portion 11a that overlaps the concave curved surface 9b when viewed in the direction perpendicular to the head placement surface 9a is configured to be thinner or softer than other portions so as to be easily deformed along the concave curved surface 9b. The head buffer portion 11a contacts the head of the infant B not only from below but also from the vertical and horizontal directions.

[0042] The infant pillow 1A configured as described above holds the occipital region of the infant B by the concave curved surface 9b. At this time, the head buffer portion 11a disperses the pressure applied to the head of the infant B from the concave curved surface 9b. Therefore, the infant pillow 1A holds the head of the infant B by the concave curved surface 9b, thereby suppressing the slipping and rolling of the infant B due to the inclination of the infant pillow 1A, dispersing the force generated on the head of the infant B by the head buffer portion 11a, and alleviating the discomfort.

[0043] Heat, sweat, etc. emitted from the head and back of the infant B pass through the cushion 11, the head placement portion 9, the shoulder placement portion 3, and the cover 8, and are discharged from the space between the head placement portion 9 and the shoulder placement portion 3 and the bedding surface G (see the arrow). Therefore, the heat conductivity and breathability of the infant pillow 1A are higher than those of a pillow constituted by a soft material such as polyurethane and installed in close contact with the bedding surface G.

[0044] Further, the infant pillow 1A holds the portion of the head of the infant B that is located closest to the bedding surface G side at a predetermined position on the bedding surface G side with respect to the virtual plane P including the shoulder placement surface 3a by the concave curved surface 9b, thereby maintaining the supine position in a posture equivalent to the standing posture. Therefore, it is possible to maintain the natural supine position of the infant B while holding the head of the infant B at a position higher than the shoulders and abdomen of the infant B. Thereby, it is possible to suppress the regurgitation of the infant B while maintaining the comfort of the infant B.

[0045] <Modification Example of Embodiment 2> A modification example of the infant pillows 1 and 1A, the infant pillow 1B, will be described with reference to FIG. 9. FIG. 9 is a side view of the infant pillow 1B, which is a modification example of the infant pillow 1A in the embodiment of the present invention, with the inclination angle adjusted.

[0046] As shown in FIG. 9, the infant pillow 1B may be configured such that the connection angle of the support portion 6 with respect to the head placement portions 2 and 9 can be changed with respect to the head placement portions 2 and 9 (the head placement portion 9 in the present embodiment). The infant pillow 1B includes a head placement portion 9, a shoulder placement portion 3, a support portion 6, a cushion 11, a cover 8, and a connection portion 6c.

[0047] The connection portion 6c connects the support portion 6 and the head placement portion 9. Further, the connection portion 6c changes the angle of the support portion 6 with respect to the head placement portion 9. The connection portion 6c is configured to be rotatable about a rotation axis extending in the width direction of the head placement portion 9. The connection portion 6c can hold the support portion 6 at an arbitrary angle with respect to the head placement portion 2. The support portion 6 changes the height from one end on the head side of the head placement portion 9 among the head placement portion 9 and the shoulder placement portion 3 to the bed surface G by the rotation of the connection portion 6c. Therefore, the support portion 6 inclines the shoulder placement portion 3 and the head placement portion 9 so that the height from the bed surface G increases from the shoulder placement portion 3 toward the head placement portion 9. Further, the support portion 6 can adjust the inclination angle of the shoulder placement portion 3 and the head placement portion 9 with respect to the bed surface G. The support portion is configured, for example, to be able to adjust the inclination angle of the shoulder placement portion 3 in the range of 5° to 20°.

[0048] The infant pillow 1B configured as described above can adjust the angles of the head placement portions 2 and 9 and the shoulder placement portion 3 with respect to the bed surface G according to the infant's age, body type, and degree of regurgitation. Therefore, the infant pillow 1B can maintain a posture suitable for the state of the infant B while holding the head of the infant B at a position higher than the shoulders and abdomen of the infant B. Thereby, regurgitation of the infant B can be suppressed while maintaining the comfort of the infant B.
