Description

Weaning meal with spoon Field of invention

The present invention relates to a weaning meal spoon, which is suitable for infants and young children's weaning meal intake, oral width, etc., and can be used to feed infants and young children.

Background of the invention

Among the tableware used when people consume food, there are various tools such as chopsticks, forks, and cups. However, the best cutlery for infants during weaning is a spoon. The spoon is different from other tableware, and most of them have no sharp shape. It is quite reassuring as a tableware for infants and toddlers, and keeps the infants ingesting fluid food or moisture during the weaning period to make them ingested. Great use.

As a spoon suitable for infants and young children, for example, a weaning meal spoon provided with a positioning mechanism is known, which can limit the degree of penetration of the spoon into the entrance cavity when feeding the infant with a solid or semi-solid weaning meal ( Patent Document 1). After the spoon is inserted into the baby's mouth, the positioning mechanism is used to hold the lip, thereby limiting the penetration of the spoon. This degree of penetration is limited to the food that the infant can use on the spoon to pick up the spoon and learn to carry it to the mouth of the mouth.

Summary of invention

During lactation, infants and young children will have a large negative pressure between the tongue and the palatum during the breastfeeding process called Peristaltic Motion. The milk is sucked into the mouth. The milk sucked into the mouth is lifted up by the tongue, so that the space generated between the tongue and the flap is closed, transferred to the throat, and the milk is drunk. This type of action is called sucking reflex (breasting reflex), and even if it enters the weaning period, it does not disappear immediately. If a tangible object is to be placed in the mouth of an infant who has a sucking reflex, there is an action to be pushed back by the tongue. For example, in order to take a weaning meal on a spoon, an infant must perform an action of closing the upper and lower lips to sharpen the milk meal. Its action is hindered by sucking reflections. Therefore, if you want to use a spoon to make a weaning meal, you must envisage some creative countermeasures for the protruding action of the tongue of the infant during the weaning period. Otherwise, it will even hinder the learning of the tongue or lips suitable for ingesting the weaning meal. The shackles of the voluntary movement.

Accordingly, the present invention is directed to providing a spoon for a weaning meal, which is capable of suppressing the protruding tongue of an infant when feeding a weaning meal to a baby with a spoon.

Hereinafter, the weaning meal spoon of the present invention will be described. Further, in order to facilitate the understanding of the present invention, the reference symbols of the attached drawings are noted in parentheses, but the present invention is not limited to the illustrated embodiments.

The weaning meal spoon (1) of the present invention has the following elements, and has the above-mentioned problems: that is, a round spoon portion (2) and a handle portion (3), and the round spoon portion (2) is formed with a groove ( 4), wherein the handle (3) is connected to the round spoon portion; the round spoon portion has a front connecting surface (13, 13', 13"), which is connected to the front end portion (10) and the bottom portion (11) And forming a portion of the peripheral surface (12); the thickness (t1) of the front end portion in the depth direction of the groove is set to be smaller than the maximum height (t2+Dm) of the aforementioned round portion in the depth direction And the round key portion is located at a position retreating from the front end portion toward the shank portion; the front connecting surface has a first curved surface (13a) that is adjacent to the front end portion and is adjacent to the concave portion The second curved surface (13b) is smoothly connected to the first curved surface, and protrudes toward the side away from the groove to be in close contact with the bottom.

According to the spoon for the weaning meal, the first curved surface (retracted toward the side of the groove of the round spoon) is connected to the second curved surface (projecting toward the side away from the groove), thereby forming a connection Since the front end portion and the bottom portion are connected to the front side, the front connecting surface is disposed at a position facing the front end side at a position where the front end portion of the round key portion is retracted toward the shank portion side. Therefore, when the weaning meal is placed in the mouth of the infant in the state of the round spoon, even if the infant wants to stick the tongue out due to breast reflex, the tip of the tongue will hit the front side of the round spoon. Therefore, the protruding motion of the tongue of the young child can be suppressed. Thereby, when the round spoon portion is inserted into the oral cavity of the infant, the tongue of the infant can be placed in the oral cavity further than the lip. Therefore, it is easy for the infant to learn to close the lips to grind the action of the weaning meal on the round spoon. Moreover, since the first curved surface immediately adjacent to the front end portion is disposed closer to the side of the groove Retreat, so the boundary between the front end and the front connection surface will be curved. Therefore, since the shape of the front end portion close to the front connecting surface is easily matched to the shape of the tip of the infant, the peculiar feeling when the tongue tip of the infant is prevented from coming to the front connecting surface can be alleviated. The thickness of the front end portion is set to be smaller than the maximum height of the round spoon portion on the side of the handle portion than the front end portion, so that the tongue of the infant can be guided to the front connecting surface, and the front end portion can be extended into the entrance cavity to be utilized. The above function of the front connection surface.

In one aspect of the invention, the thickness (t1, t2) of the round spoon portion in the depth direction of the groove is configured such that the front end portion gradually increases toward the bottom portion, and the round key portion is also formed. can. Thereby, the thickness of the round spoon portion can be increased to ensure the area or height of the front joint surface, and the maximum depth of the groove can be reduced to the extent suitable for ingesting the weaning meal.

In one aspect of the invention, the maximum depth (Dm) of the groove may be set to be smaller than the aforementioned thickness (t2) of the bottom portion. Thereby, the area or height of the front joint surface can be sufficiently ensured, and the maximum depth of the groove can be limited to be small, so that the volume of the groove can be easily adapted to the intake of a weaning meal.

In one aspect of the spoon for the weaning meal of the present invention, the thickness of the front end portion is larger than the maximum depth of the groove, and the thickness of the bottom portion may be twice or more the thickness of the front end portion. According to this aspect, since the depth of the groove is relatively shallow in terms of the overall size of the round spoon portion, it is difficult to leave uneaten food in the groove of the round spoon portion.

The respective dimensions of the round spoon portion of the present invention may be appropriately set as long as the above-described features are satisfied. Preferably, the thickness of the tip end portion of the round spoon portion may be set in the range of 1.5 to 3.0 mm. And before The aforementioned thickness of the bottom portion of the round spoon portion is set within a range of 3.0 to 8.0 mm, and the aforementioned maximum depth of the groove is set within a range of 0.5 to 2.5 mm.

The shape of the front end portion of the round key portion or the shape of the front connecting surface can be appropriately set as long as it has the above characteristics. For example, when the groove of the round spoon portion is viewed from the front, the front end portion is formed in an arc shape having a vertex (P) on a center line (CL) of the shank portion, or the front end portion is coupled to the shank portion The center line may be formed in a straight line extending in the orthogonal direction. Further, when the groove of the round key portion is viewed from the front, the front connecting surface (13) is offset from the intersection point (P) of the front end portion and the center line of the shank portion toward the shank side. The position (P') may extend linearly in a direction orthogonal to the center line; or the front connecting surface (13') may intersect the center line of the front end portion and the front end portion The point is more biased toward the position where the shank side is offset, and the manner of retreating toward the shank side may be curvedly extended; or the front connecting surface (13") may be at the front end portion and the shank portion. The intersection of the center line is more inclined toward the position where the shank side is offset, and the manner of protruding toward the front end side is curved. When the front connecting surface is formed into a linear shape or a curved shape that retreats toward the shank side The tongue of the infant that is in contact with the front connection surface is hard to be slid to the left and right, so that the protrusion of the tongue can be surely suppressed. On the other hand, when the front connection surface is formed into a curved shape that protrudes toward the front end side, it can be improved. Suppresses the effect of the tongue, and When the round spoon is obliquely inserted into the oral cavity of the infant, the tongue of the infant can also be sufficiently pressed at the front joint surface.

In the spoon for the weaning meal of the present invention, the round spoon portion and the shank portion are arranged horizontally in a state in which the groove is facing upward, The shank portion may be formed to have a higher height difference than the round spoon portion, and may be configured separately. According to this aspect, when the round key is set horizontally, the handle will be located above the rounded spoon. Therefore, the helper can place the round spoon in a horizontal state while holding the handle to feed the baby in the weaning meal contained in the round spoon, and extend the round spoon into the oral cavity of the infant from obliquely above. Inside. Thereby, it is possible to prevent the weaning meal from overflowing from the round spoon, and it is not necessary to match the height of the caregiver's hand to the height of the mouth of the infant, so that the feeding of the infant can be easily performed.

In this aspect, the shank portion may have a convex shape on the upper side and a curved side in the longitudinal direction. At this time, when the baby is nurtured by holding the handle in the same manner as holding the pencil, the rounded portion can be kept horizontal while the wrist of the caregiver is bent upward. Thereby, it is easier to finely adjust the angle of the spoon held by the nurturer compared with the case where the round key portion must be kept horizontal in the state of stretching the wrist, thereby improving the ease of feeding.

In the spoon for the weaning meal of the present invention, when the aforementioned spoon portion is disposed horizontally in a state in which the groove is facing upward, the shank is flat in the transverse direction and has a curvature on the lower side. A shape larger than the curvature of the upper side may also be used. According to this aspect, the lower end surface of the handle can be easily applied to the finger abdomen on the arch formed by the thumb of the caregiver and the finger roots of the index finger, and the fingertip of the index finger is easily attached to the handle. Upper end face.

In the spoon for the weaning meal of the present invention, when the groove of the round spoon portion is viewed from the front, the width (Wd) of the round spoon portion orthogonal to the center line of the shank portion is set at It can also be in the range of 14~30mm. Thereby, the effect of pressing the tongue of the infant can be ensured, and the width of the round spoon can be surely set to be smaller than the mouth of the infant within the age range of the weaning meal. The cavity is wide, so that the effect of the spoon for the weaning meal of the present invention can be fully exerted.

As described above, according to the present invention, since the front connecting surface is disposed to face the front end side, it is disposed at a position away from the front end portion of the round spoon portion toward the shank portion, and therefore, when the weaning meal is contained in the round spoon portion When it is inserted into the mouth of an infant, even if the infant wants to protrude the tongue due to breast reflex, the tip of the tongue will also abut the joint surface of the round spoon. Thereby, the protruding action of the tongue of the young child can be suppressed.

Form for implementing the invention

Fig. 1 is a front view of a weaning meal spoon of one embodiment of the present invention, and Fig. 2 is a view showing a state of a weaning meal spoon of Fig. 1 viewed from the direction of arrow II. Fig. 3 is a cross-sectional view taken along line III-III of Fig. 1, and Fig. 4A to Fig. 4D are lines IVa-IVa, IVb-IVb, IVc-IVc, and IVd-IVd of Fig. 2; Sectional drawings of the line.

The weaning spoons (hereinafter referred to as spoons) 1 shown in the figures are used by the caregiver such as a mother or a nurse to feed the infants with a weaning meal. The spoon 1 is provided with a rounded spoon portion 2 for holding a weaning meal and holding it, and a handle 3 for attaching to the round spoon portion 2. A groove 4 is formed in the round spoon 2 to hold the weaning meal. The shank portion 3 has a sufficient length with respect to the round spoon portion 2, and specifically has a length of about four times the size of the longitudinal direction of the round spoon portion 2 (the left-right direction of the first to third figures). The spoon 1 is inserted into the mounting hole 5 formed in the rounded portion 2 by the connecting portion 6 formed on the handle portion 3, thereby connecting the round spoon portion 2 and the handle portion 3.

The round spoon 2 and the handle 3 of the spoon 1 are made of different materials. As the material of the round spoon portion 2, a material which does not give a baby a hard touch or an icy touch when inserted into the oral cavity of an infant is selected. In the spoon 1, a thermoplastic elastomer having the same elasticity as that of the vulcanized rubber is used as the material of the round spoon portion 2. Further, polypropylene of plastic is used as the material of the handle 3. In order to improve the slip resistance or the appearance of the handle 3, the entire peripheral surface of the handle 3 is applied. It is processed to impart fine unevenness such as a satin pattern or a leather pattern. Further, the round part 2 and the handle 3 may be made of the same material or may be of an integral structure. The uneven processing of the handle 3 can also be omitted.

As shown in Fig. 1, the head portion 2 is provided with a head portion 7 and a neck portion 8, and the former head portion 7 is provided with a groove 41 having a substantially elliptical shape, and the latter neck portion 8 is immediately adjacent to the head portion. The portion 7 is formed with the above-described mounting hole 5. The front end portion 10 of the round spoon portion 2 is formed in an arc shape having a vertex P on the center line CL of the handle portion 3. As shown in Fig. 3, in the round key portion 2, the thickness of the groove 4 in the depth direction is not constant, but is gradually increased from the front end portion 10 toward the bottom portion 11. The thickness t1 of the front end portion 10 is set to be smaller than the maximum height in the depth direction of the round key portion 2 (a position retracted from the front end portion 10 toward the side of the shank portion 3), that is, smaller than the maximum depth Dm of the groove 4. The value (t2+Dm) after summing up the thickness t2 of the bottom portion 11. Further, the maximum depth Dm of the groove of the round spoon portion 2 is set to be smaller than the thickness t2 of the bottom portion 11. Further, the thickness t1 of the front end portion 10 is set to be larger than the maximum depth Dm of the groove 4, and the thickness t2 of the bottom portion 11 is set to be twice or more the thickness t1 of the front end portion 10. Thereby, the area or height of the front connection 13 can be sufficiently ensured, and the groove 4 can be formed shallow, and the volume of the groove 4 can be set small to fit the intake of the first wean meal. A suitable range of the maximum depth Dm of the groove 4 is 0.5 to 2.5 mm. If the maximum depth Dm is less than 0.5 mm, the amount of weaning meal that the groove 4 can accommodate will be too small, and once the maximum depth Dm exceeds 2.5 mm, there will be too much weaning meal that the groove 4 can accommodate. Further, the appropriate range of the thickness t1 is 1.5 to 3.0 mm, and the appropriate range of the thickness t2 is 3.0 to 8.0 mm. When the thickness t1 of the front end portion 10 is less than 1.5 mm, the front end portion 10 may be too thin for the lips of the infant, and once it exceeds 3.0 mm, There is a possibility that the front end portion 10 is prevented from smoothly extending into the oral cavity of the infant. Further, if the thickness t2 of the bottom portion 11 is less than 3.0 mm, it is difficult to ensure the full height of the round key portion 2 and the groove 4 is formed at a shallow depth, and once the thickness t2 exceeds 8.0 mm, there is a round spoon portion. 2 is too thick to be placed in the mouth of infants and young children. More specifically, the thickness t1 is set to 2.2 mm, the thickness t2 is set to 5.5 mm, and the depth Dm is set to 1.5 mm, whereby the maximum height (t2+Dm) of the round key portion 2 is 7.0 mm. . However, the shape of the distal end portion 10 is not limited to an arc shape, and other shapes will be described later.

As shown in FIGS. 1 to 3, the round key portion 2 has a front connecting surface 13 which is in contact with the front end portion 10 and the bottom portion 11 and forms a portion of the peripheral surface 12 (refer to FIG. 2). On the other hand, the remaining portion of the peripheral surface 12 of the round spoon portion 2 is a single curved surface 14 which is formed on the side away from the groove 4 and which is formed on the curvature without reversal (refer to FIG. 4D).

As shown in Fig. 1, the front connecting surface 13 is linearly extended in a direction orthogonal to the center line CL at a position P' shifted from the apex P of the distal end portion 10 toward the shank portion 3. Further, as shown in FIGS. 2 and 3, the front connecting surface 13 has a first curved surface 13a and a second curved surface 13b, and the former first curved surface 13a is immediately adjacent to the front end portion 10 toward the side of the recess 4. The second curved surface 13b of the latter is smoothly connected to the first curved surface 13a and protrudes away from the side of the groove 4 to be in close contact with the bottom portion 11. The curved directions of the curved faces 13a, 13b are opposed to each other, and the curved faces 13a, 13b are connected to each other at a joint point C which can be used as a bending point concept in FIGS. 2 and 3.

In this way, since the front connecting surface 13 is formed by two curved surfaces 13a and 13b which are different from each other in the bending direction, the front connecting surface 13 is oriented toward In the state of the front end side, it is disposed at a position retreating from the front end portion 10 of the round key portion 2 toward the side of the shank portion 3. As shown in Fig. 5, since the front connecting surface 13 is disposed in the above-described manner, even when the caregiver H is placed in the round spoon portion 2 with the weaning meal F, the spoon 1 is inserted into the mouth of the infant I, even if Infant I wants to protrude the tongue T due to breast-feeding reflex, and the tip of the tongue also abuts against the front connecting surface 13 of the round spoon 2, thereby suppressing the protruding action of the tongue T of the child I. When the spoon 1 is further inserted inwardly from the state of Fig. 5, the tongue T can be stagnated in the oral cavity further than the lip L. Therefore, it is easy for the infant I to learn to close the lip L to grind the action of the weaning meal F on the round spoon 2. Further, as is clear from FIGS. 2 and 3, the boundary between the front end portion 10 and the front connecting surface 13 is curved, so that the front end portion 10 is in the shape of the front connecting surface 13, and it is easy to match the tip of the infant. shape. Therefore, the peculiar feeling when the tip of the infant's tongue is pressed against the front connecting surface 13 can be alleviated.

Further, when the groove 4 of the round spoon portion 2 is viewed from the front (Fig. 1), the width Wd of the round spoon portion 2 in the direction orthogonal to the center line CL of the shank portion 3 is set at 14 to 30 mm. It is appropriate within the scope. If the width Wd is less than 14 mm, the area of the front connecting surface 13 is insufficient to impair the effect of suppressing the tongue of the infant. On the other hand, if the width Wd exceeds 30 mm, the round spoon portion 2 is too large, and the round spoon portion 2 cannot be smoothly extended into the object age of the spoon 1 of the present form - that is, the intake period of the weaning meal (for example, The age of the month is about 5 months) - the baby's mouth in the mouth. Incidentally, the average oral width of infants and young children from 12 months to 18 months is about 30.9 mm. In view of the fact that the spoon 1 is aimed at infants and younger children of this age, it will be wide Wd. It is reasonable to set the maximum size at 30mm.

As described above, the front end portion 10 of the round spoon portion 2 is formed in an arc shape having the apex P, so that the round spoon portion 2 is easily placed in the mouth of the infant. Further, as shown in Fig. 1, the front connecting surface 13 extends linearly in a direction orthogonal to the center line CL, so that the baby is pressed against when the front connecting surface 13 protrudes toward the front end side. The tongue of the child is harder to dod to the left and right, which can surely suppress the protrusion of the tongue.

As shown in Fig. 2 and Fig. 3, when the spoon 1 is placed such that the rounded portion 2 is horizontal with the groove 4 facing upward, the handle 3 is generated between the round portion 2 and the handle 3. The height difference ΔH of the round spoon portion 2. In other words, the spoon 1 has a round key portion 2 and a handle portion 3, respectively, so as to generate such a height difference ΔH. Since the spoon 1 has such a height difference ΔH, as shown in Fig. 5, when the nurturer H feeds the weaning meal to the infant I, the round spoon 2 can be horizontally tilted from above. Extend into the mouth of infant I. Thereby, it is possible to prevent the weaning meal from overflowing from the round spoon portion 2, and it is not necessary to match the height of the hand of the nursing person H with the height of the mouth of the infant I, so that the feeding of the infant I can be easily performed.

As shown in FIGS. 2 and 3, the shank portion 3 has a convex shape on the upper side and a curved shape in the longitudinal direction. Therefore, as shown in Fig. 5, when the caregiver H holds the handle 3 in the same manner as holding the pencil to nurture the infant I, the wrist of the caregiver H can be bent in the upper side, and the round spoon Part 2 remains horizontal. Although the illustration has been omitted, it is easier to finely adjust the angle of the spoon 1 of the caregiver H, as compared with the case where the round part is required to be horizontal in the state of extending the wrist (when the handle is linearly extended). Therefore, the ease of feeding can be improved.

As shown in Figures 4A and 4B, the handle 3 of the spoon 1 is oriented in its cross section. The transverse direction is flat and has a shape in which the curvature of the lower side is larger than the curvature of the upper side. Therefore, as shown in Fig. 5, the lower end surface of the handle 3 can be easily applied to the finger abdomen A on the arch formed between the thumb f1 of the caregiver H and the finger roots of the index finger f2, and the index finger is easily made. The fingertip of f2 is attached to the upper end surface of the handle 3.

The present invention is not limited to the above embodiments, and may be embodied in various forms within the scope of the gist of the invention. In the above aspect, the front connecting surface 13 is linearly extended in the direction orthogonal to the center line CL (refer to FIG. 1), but in addition to the shape, the front connecting may be as shown by a broken line in FIG. The surface 13' is curved in a curved manner toward the shank 3 side at a position shifted toward the shank 3 side from the apex P. In the form shown by the broken line, the tongue of the infant against the front connecting surface 13' is more difficult to dodge than the linear front connecting surface 13, so that the accuracy of suppressing the protruding motion of the tongue can be improved. Alternatively, as shown in Fig. 6, the front connecting surface 13" may be at a position P' offset from the intersection point - the apex P- of the front end portion 10 and the center line CL toward the side of the shank portion 3, toward the shank portion. 3 is in a curved manner in such a manner that the opposite side (that is, the front end portion 10 side) protrudes. At this time, by the protruding portion of the front connecting surface 13", the pressing effect on the tongue of the infant can be improved, and when the spoon is turned 2 When leaning into the mouth of an infant, it is also possible to sufficiently press the tongue of the infant to the front connecting surface 13".

The respective curvatures of the constituent elements of the front connecting surface 13 - the first curved surface 13 a and the second curved surface 13 b - may be the same or different. Each of the curved faces 13a, 13b may have a section in which the curvature is constant, and may have a section in which the curvature continuity changes. Further, each of the curved faces 13a and 13b may include a section having a curvature of 0, that is, a plane, under the condition that the bending section is present.

In the present invention, the front end portion 10 does not need to be curved to be curved. For example, as shown in FIG. 7A, the distal end portion 10 may be formed in a linear shape extending in a direction orthogonal to the center line CL of the shank portion 3. As shown in FIG. 7A, such a linear front end portion 10 and a front connecting surface 13 (linearly extending in a direction perpendicular to the center line CL at the vertex P') may be combined, or as shown in FIG. 7B. It is shown that such a linear front end portion 10 may be combined with the front connecting surface 13' (the curved portion extending toward the side of the handle portion 3 in a curved manner), or as shown in Fig. 7C, such a straight front end portion 10 may be combined with the front connecting surface 13" (curved in a curved manner so that the shank portion 3 protrudes from the opposite side).
