[0066] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0067] The present disclosure provides a feeding device, such as Figures 1 to 5 , Figures 8 to 11 As shown, it includes a main body 1 and at least one opening and closing portion 2.

[0068] The main body 1 has a receiving cavity 11 therein. A first end of the main body 1 along a first direction is provided with an inlet portion 12 communicated with the receiving cavity 11 , so that the object to be sucked can enter the receiving cavity 11 through the inlet portion 12 .

[0069] Each of the at least one opening and closing portions 2 is arranged at the second end of the main body 1 along the first direction, the second end of the main body 1 is away from the first end of the main body 1, the length of the second end of the main body 1 in the second direction is greater than the length of the second end of the main body 1 in the third direction, the opening and closing portion 2 has a slit 21 extending along a fourth direction, and the fourth direction is located in a plane perpendicular to the third direction; the first direction is the axial centerline direction of the main body 1, and the first direction, the second direction and the third direction are perpendicular to each other.

[0070] The slit 21 is in an open state when being squeezed, so that the accommodating cavity 11 is in communication with the external space of the body 1 through the slit 21 ; the slit 21 is in a closed state when not being squeezed.

[0071] According to the embodiments of the present disclosure, it should be noted that:

[0072] The object to be sucked can be liquid, solid or mixed, for example, liquid breast milk is loaded into the receiving cavity 11 of the main body 1, and then the main body 1 filled with liquid breast milk is placed in a refrigerator or other equipment for freezing to freeze the breast milk. Alternatively, the frozen breast milk is directly placed in the receiving cavity 11 of the main body 1.

[0073] The first direction A (such as Figure 1 , Figure 3 , 4 As shown) can be understood as: the axis direction of the body 1, the first end of the axis direction (i.e. Figure 3 , 4 The upper end of the main body shown in FIG. 1 is provided with an inlet portion 12, and the second end of the axis direction (i.e. Figure 3 , 4 An opening and closing portion 2 is provided at the lower end of the main body shown in FIG.

[0074] The second direction B can be understood as: Figure 3 , Figure 4 Further, because the first direction A, the second direction B and the third direction C (such as Figure 1 As shown in the figure, the two are perpendicular to each other, and the length of the second end of the body 1 in the second direction B is greater than the length of the second end of the body 1 in the third direction C. It can be understood that the second end of the body 1 is a structure that is generally in a flat mouth shape, that is, the cross-section or projection shape of the second end of the body 1 on the plane perpendicular to the first direction A (the plane where the second direction B and the third direction C are located) is elliptical or oblong, so that the infant can put the second end of the body 1 into the mouth by slightly opening the mouth, and it is also convenient for the infant to chew.

[0075] like Figure 3 and Figure 4 As shown, the fourth direction can be understood as an arc or linear direction from left to right or from right to left along the end of the second end of the body 1 in a plane where the first direction A and the second direction B are located.

[0076] like Figure 3 and Figure 4 As shown, the fourth direction can also be understood as an arc or linear direction from left to right or from right to left along the end of the second end of the body 1 in a plane parallel to the plane where the first direction A and the second direction B are located.

[0077] The opening and closing portion 2 can be arranged at the second end of the body 1 or at a position close to the second end of the body 1. Further, the shape of the opening and closing portion 2 can be various. In one embodiment, the opening and closing portion 2 is a strip-shaped opening and closing portion 2, and the strip-shaped opening and closing portion 2 extends along the fourth direction, that is, the length of the strip-shaped opening and closing portion 2 in the fourth direction is greater than the length in the third direction C. For example, the length of the strip-shaped opening and closing portion 2 in the fourth direction is greater than or equal to 3mm, and less than or equal to 5mm, such as 3mm, 3.5mm, 4mm, 4.5mm, 4.8mm, 5mm, etc., which is not limited here; the length of the strip-shaped opening and closing portion 2 in the third direction C is greater than or equal to 0.6mm, and less than or equal to 2mm, such as 0.6mm, 0.7mm, 0.9mm, 1mm, 1.2mm, 1.5mm, 2mm, etc., which is not limited here. Among them, the fourth direction is located in the plane where the first direction A and the second direction B are located or in a plane parallel to the plane where the first direction A and the second direction B are located. Furthermore, the projection of the opening and closing portion 2 on the plane can have various shapes. For example, the projection of the opening and closing portion 2 on the plane is an arc or a straight line, that is, the end of the second end of the main body 1 can be an arc-shaped end structure or a rectangular end structure; further, the projection of the slit 21 on the plane can be an arc or a straight line. When the projection of the opening and closing portion 2 on the plane is an arc, the projection of the slit 21 on the plane is also an arc; when the projection of the opening and closing portion 2 on the plane is a straight line, the projection of the slit 21 on the plane is also a straight line; wherein, the length of the slit 21 extending along the fourth direction should not be greater than the length of the opening and closing portion 2 extending along the fourth direction. The length of the slit 21 extending along the fourth direction is greater than or equal to 2.5 mm and less than or equal to 4.5 mm. For example, it can be 2.5 mm, 3 mm, 3.2 mm, 3.5 mm, 4 mm, 4.5 mm, etc. There is no limitation here, as long as the length of the slit 21 extending along the fourth direction is not greater than the length of the opening and closing part 2 extending along the fourth direction.

[0078] In the case where there are multiple opening and closing parts 2, the multiple opening and closing parts 2 can be arranged in any direction, for example, two adjacent opening and closing parts 2 are arranged at intervals along the fourth direction, or are arranged at intervals along the third direction C.

[0079] The slit 21 can be understood as an opening provided in the opening and closing portion 2, and the slit can be opened and closed. Furthermore, at least the portion of the opening and closing portion 2 close to the slit 21 is flexible. When the slit 21 is squeezed, the slit 21 is in an open state, and the accommodating cavity 11 is connected to the external space of the body 1 through the opened slit 21. When the slit 21 is not squeezed, the slit 21 is in a closed state, and the opening and closing portion 2 can isolate the accommodating cavity 11 from the external space of the body 1. When the liquid is introduced into the accommodating cavity through the inlet portion, when the slit is in a closed state, the liquid in the accommodating cavity will not flow out from the slit.

[0080] The inlet 12 can be understood as a structure for inputting the object to be sucked into the accommodating chamber 11. After the object to be sucked is input, the sealing member 5 is connected to the inlet 12 to form a closed space in the accommodating chamber 11. When cleaning the accommodating chamber 11, the sealing member 5 can also be removed and the accommodating chamber 11 can be cleaned through the inlet 12.

[0081] In one embodiment, the body 1 is made of a material with a certain flexibility, so that when the outer wall of the body 1 is subjected to pressure, the body 1 is deformed toward the accommodating cavity 11, so that the pressure in the accommodating cavity 11 is greater than the pressure outside the body 1, and the slit 21 is opened to facilitate the discharge of the sucked object. At the same time, the body 1 with a certain flexibility will not cause damage to the oral cavity and gums of the infant after being placed in the infant's mouth. For example, the body 1 is made of silicone.

[0082] When the feeding device is used, liquid breast milk is input into the accommodating chamber 11 of the main body 1 through the inlet portion 12. After the input is completed, the sealing member 5 is connected to the inlet portion 12 to form a closed space in the accommodating chamber 11. The feeding device is then frozen and placed in the mouth of an infant. The infant chews the feeding device so that the temperature of the infant's gums contacts the feeding device for heat exchange, thereby lowering the gum temperature and relieving the pain of the gums during the teething period. At the same time, the feeding device liquefies the frozen breast milk after absorbing heat. The slit 21 is squeezed and opened by the chewing and sucking of the infant, and the liquefied breast milk flows into the infant's mouth through the opened slit 21. The liquefied breast milk still has a relatively low temperature, which can further lower the gum temperature and relieve the pain of the gums.

[0083] According to the embodiments of the present disclosure, the accommodating cavity 11 can accommodate frozen objects to be sucked, and the temperature of the gums of infants and young children can be lowered and the pain of the gums can be relieved by biting the main body 1. At the same time, the sucking and biting of the infants and young children can make the liquid objects to be sucked flow into the infant's mouth through the slit 21, further lowering the temperature of the gums and relieving the pain of the gums. The slit 21 is arranged along the fourth direction, which can increase the coverage area of ​​the liquid objects to be sucked flowing into the infant's mouth, so that the liquid objects to be sucked can contact the gums faster, thereby accelerating the efficiency of relieving the pain of the gums. At the same time, after the slit 21 arranged along the fourth direction has been bitten by the infant for many times, the opening and closing part 2 still has a closing function, thereby increasing the service life of the main body 1.

[0084] In one embodiment, the direction from the external space of the body 1 to the accommodating cavity 11 is the wall thickness direction, and the wall thickness of the body 1 is greater than the wall thickness of the opening and closing portion 2 .

[0085] According to the embodiments of the present disclosure, it should be noted that:

[0086] The wall thickness of the body 1 is the distance between the inner wall of the body 1 and the outer wall of the body 1. The wall thickness of the opening and closing portion 2 is the distance between the inner wall of the opening and closing portion 2 and the outer wall of the opening and closing portion 2.

[0087] It can be understood that the opening and closing portion 2 is equivalent to a thin-walled structure. In one embodiment, the wall thickness of the main body 1 is greater than or equal to 0.8 mm and less than or equal to 2.2 mm, for example, it can be 0.8 mm, 1 mm, 1.5 mm, 1.8 mm, 2 mm, 2.2 mm, etc., which is not limited here. The wall thickness of the opening and closing portion 2 is greater than or equal to 0.5 mm and less than or equal to 1.8 mm, for example, it can be 0.5 mm, 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.8 mm, etc., which is not limited here.

[0088] According to the embodiment of the present disclosure, the opening and closing portion 2 is provided with a thinner wall thickness, so that when the slit 21 is squeezed, it can be opened more smoothly, so that the object to be sucked can enter the oral cavity of the infant.

[0089] In one embodiment, Figures 1 to 4 , Figures 8 to 11 As shown, when the main body 1 is provided with a plurality of opening and closing portions 2, two adjacent opening and closing portions 2 are spaced apart along the fourth direction.

[0090] According to the embodiments of the present disclosure, it should be noted that:

[0091] The number of the plurality of opening and closing parts 2 needs to be determined according to the length of the second end of the body 1 along the fourth direction (that is, the number of the opening and closing parts 2 is determined according to the length of the second end of the body 1). When the length is longer, more opening and closing parts 2 can be set, and when the length is shorter, the number of opening and closing parts 2 can be set is smaller, for example, 3 opening and closing parts 2 can be set. Further, the distance between any two adjacent opening and closing parts 2 in the plurality of opening and closing parts 2 is greater than or equal to 1 mm, and less than or equal to 3 mm, for example, it can be 1 mm, 1.1 mm, 1.2 mm, 1.8 mm, 2 mm, 2.1 mm, 2.2 mm, 2.5 mm, 2.8 mm, 33 mm, etc., which is not limited here.

[0092] According to the embodiment of the present disclosure, when the slit 21 is squeezed, the area covered by the sucked object flowing into the infant's mouth through the slits 21 of the multiple opening and closing parts 2 spaced apart along the fourth direction is larger, further accelerating the efficiency of relieving gum pain.

[0093] In one embodiment, Figure 1 , Figure 2 , Figure 4 As shown, the outer side wall of the second end of the body 1 is provided with a concave-convex portion 3 for increasing the surface roughness.

[0094] According to the embodiments of the present disclosure, it should be noted that:

[0095] The concavo-convex portion 3 may be disposed on the outer side wall of the end portion of the body 1 close to the second end. When the second end of the body 1 is placed in the mouth of an infant, the concavo-convex portion 3 may contact the gums.

[0096] According to the embodiment of the present disclosure, during the chewing process of infants and young children, the concave-convex portion 3 contacts the gums, rubbing the gums, massaging the gums, and thus relieving the pain of the gums.

[0097] In one embodiment, Figure 1 As shown, the concave-convex portion 3 includes a plurality of dot-shaped grooves dispersedly arranged on the outer side wall of the second end of the body 1 .

[0098] According to the embodiments of the present disclosure, it should be noted that:

[0099] A plurality of dot-shaped grooves may be dispersedly arranged on the outer wall of the second end of the main body 1, specifically, may be arranged along the circumference of the second end of the main body 1, or may be dispersedly arranged on the outer wall of the two side walls of the second end of the main body 1 along the third direction C, so as to contact the gums when the child chews.

[0100] According to the embodiment of the present disclosure, by distributing a plurality of dot-shaped grooves on the outer wall of the second end of the body 1, the wall thickness of the second end at the groove can be reduced, and the flexibility of the second end can be increased. When the infant is biting, the second end is more likely to be deformed, making it easier for the infant to bite. At the same time, it can also massage the gums of the infant.

[0101] In one embodiment, Figure 2 As shown, the concave-convex portion 3 includes at least one annular groove, and each of the at least one annular groove is arranged around the second end of the body 1.

[0102] According to the embodiments of the present disclosure, it should be noted that:

[0103] In the case where the concavo-convex portion 3 includes a plurality of annular grooves, the plurality of annular grooves are arranged along the first direction A at intervals.

[0104] According to the embodiment of the present disclosure, by providing an annular groove surrounding the second end of the body 1, the wall thickness of the second end at the annular groove can be reduced, the flexibility of the second end can be increased, and the second end is more likely to deform during the chewing process of infants and young children, making chewing easier for infants and young children. At the same time, it can also massage the gums of infants and young children.

[0105] In one embodiment, Figure 3 , Figure 4 As shown, the feeding device also includes:

[0106] The abutment portion 4 is protrudingly disposed on the outer side wall of the inlet portion 12 . The abutment portion 4 extends along the circumference of the inlet portion 12 . The abutment portion 4 is used to be snap-connected with a second cover body disposed outside the second end of the body 1 .

[0107] According to the embodiments of the present disclosure, it should be noted that:

[0108] The abutting portion 4 may extend along the circumference of the inlet portion 12 to form a ring-shaped structure or an arc-shaped structure, or may be a plurality of segmented arc-shaped structures formed along the circumference of the abutting portion 4 .

[0109] When used for freezing the object to be sucked in the main body 1, the second cover body is placed on the second end of the main body 1 and is moved along the first direction A toward the abutment portion 4 until the second cover body is engaged with the abutment portion 4, so that the second end of the main body 1 is accommodated in the internal space of the second cover body, thereby preventing the main body 1 from contacting the external environment when the object to be sucked is frozen.

[0110] According to an embodiment of the present disclosure, by providing abutment portion 4, when the second end of the main body 1 cooperates with the second cover body, the connection between the second cover body and the second end of the main body 1 can be made more secure, thereby preventing the second cover body from falling off and causing the second end of the main body 1 to contact the external environment and contaminate the second end of the main body 1 and the opening and closing portion 2.

[0111] In one embodiment, Figure 1 , Figure 2 As shown, a first ventilation groove 41 is further provided on the abutting portion 4. The first ventilation groove 41 is used to connect the inner and outer spaces of the second cover body when the abutting portion 4 is engaged with the second cover body.

[0112] According to the embodiments of the present disclosure, it should be noted that:

[0113] The first ventilation groove 41 may be an opening provided on the abutting portion 4 along the first direction A, or may be an opening formed on the abutting portion 4 itself. For example, when the abutting portion 4 is extended along the circumference of the entrance portion 12 to form an annular abutting portion 4, an opening may be provided on the annular abutting portion 4. Or when the abutting portion 4 is extended along the circumference of the entrance portion 12 to form an arc-shaped abutting portion 4, the gap formed between the two ends of the arc-shaped abutting portion 4 along the circumference of the entrance portion 12 is the opening. Or when the abutting portion 4 is extended along the circumference of the entrance portion 12 to form a plurality of segmented arc-shaped abutting portions 4, the spacing between the plurality of segmented abutting portions 4 is formed as an opening.

[0114] The length of the first ventilation groove 41 along the first direction A can be adjusted to meet the requirement of connecting to the internal space of the second cover body. That is to say, when the first ventilation groove 41 is arranged on the second end of the main body 1 of the second cover body, one end of the first ventilation groove 41 extends to the internal space of the second cover body, and the other end of the first ventilation groove 41 extends to the external space of the second cover body.

[0115] According to an embodiment of the present disclosure, when the second cover body covers the second end of the main body 1 for freezing, the air pressure in the internal space of the second cover body will decrease. The air pressure in the internal and external spaces of the second cover body can be balanced through the first ventilation groove 41, thereby preventing the negative pressure environment formed in the internal space of the second cover body from causing the object to be sucked to flow out of the main body 1 through the slit 21.

[0116] In one embodiment, the inner side wall of the inlet portion 12 is provided with a first groove 22 , and the first groove 22 is used for engaging with the protrusion 522 of the sealing member 5 , so that the inlet portion 12 is sealedly connected with the sealing member 5 .

[0117] According to an embodiment of the present disclosure, a first groove 22 is provided on the inner wall of the entrance portion 12 to increase the contact area of ​​the inner wall thereof. When connected with the protrusion 522 of the seal 5, the friction between the entrance portion 12 and the seal 5 can be increased to prevent the seal 5 from falling off the main body 1.

[0118] The present disclosure provides a feeding device, such as Figures 8 to 11 As shown, it includes a sealing member 5 and a feeding device in any of the above embodiments.

[0119] Seal 5 (such as Figures 5 to 7 As shown in the figure, the first cover body 51 includes a first cover body 51 and a boss 52 protruding from one end surface of the first cover body 51.

[0120] The inlet portion 12 of the feeding device is detachably connected to the sealing member 5 .

[0121] When the inlet 12 is connected to the sealing member 5 , the first cover body 51 covers the inlet 12 , the boss 52 is inserted into the inlet 12 , and the outer wall of the boss 52 is interference fit with the inner wall of the inlet 12 .

[0122] According to the embodiments of the present disclosure, it should be noted that:

[0123] When the feeding device is connected with the sealing member 5, the first cover body 51 of the sealing member 5 covers the inlet 12 of the feeding device to close the inlet 12, so that the accommodating cavity 11 of the feeding device forms a closed space, and the boss 52 of the sealing member 5 is inserted into the inlet 12 of the feeding device, so that the outer side wall of the boss 52 of the sealing member 5 is connected with the inner side wall of the inlet 12, wherein the size of the boss 52 of the sealing member 5 can be the same as the size of the inlet 12 so that the two are connected in a matched manner (such as Figure 8 , Fig. 9 As shown), or the size of the boss 52 of the seal 5 is larger than the size of the inlet 12 so that the two are interference fit (as shown Fig.10 , Fig.11 As shown). Furthermore, the other end of the seal 5 may be provided with a handle, which is convenient for the infant to grasp when using the feeder. For example, the infant can put the second end of the body 1 into the mouth by grasping the handle. When the feeding device cooperates with the seal 5, the seal 5 closes the inlet 12, and a closed space is formed in the receiving cavity 11 of the feeding device, which is conducive to storing the object to be sucked for freezing. When the seal 5 is disassembled from the feeding device, it is convenient to clean the receiving cavity 11 of the feeding device and input new objects to be sucked into the receiving cavity 11.

[0124] According to the embodiments of the present disclosure, by providing a detachable connection between the feeding device and the sealing member 5, it is convenient to input the object to be sucked into the feeding device and to clean the feeding device. By providing an interference fit between the boss 52 of the first cover body 51 and the entrance portion 12, the connection between the boss 52 and the entrance portion 12 can be made tighter, thereby preventing the sealing member 5 from falling off the feeding device.

Furthermore, during the connection between the seal 5 and the inlet 12, part of the air in the accommodating chamber 11 can be discharged to the external space of the feeding device through the second ventilation groove 521, so as to avoid temporary storage of a large amount of air in the accommodating chamber 11, which causes the sucked material to flow out from the slit 21 when the seal 5 and the inlet 12 are connected. After the seal 5 and the inlet 12 are fully matched, the second ventilation groove 521 is in a closed state and does not connect the accommodating chamber 11 with the external space of the feeding device. In other words, it can be understood that the depth of the second ventilation groove 521 on the boss 52 is less than the height of the inner side wall of the inlet 12. When the seal 5 and the inlet 12 are connected, the boss 52 is inserted into the inlet 12, and the inner side wall of the inlet 12 completely closes the second ventilation groove 521.

[0128] There may be one second vent groove 521 , or a plurality of second vent grooves 521 may be provided along the circumference of the boss 52 . For example, two second vent grooves 521 may be provided along the circumference of the boss 52 and at opposite positions of the boss 52 .

[0139] According to the embodiments of the present disclosure, it should be noted that:

[0140] The second groove 511 may be a structure formed at one end of the first cover body 51 away from the boss 52, or may be a structure formed at the end surface of the first cover body 51 away from the boss 52. Further, when the seal 5 and the inlet 12 are connected, the second groove 511 may be pressed by fingers to connect the seal 5 and the inlet 12. When the seal 5 and the inlet 12 are disassembled, the index finger may be pressed against the second groove 511, and the thumb and index finger may cooperate to grasp the diffusion part 53 to disassemble the seal 5 and the inlet 12.

[0141] According to the embodiment of the present disclosure, it is convenient to connect or disassemble the feeding device and the sealing member 5 by pressing the second groove 511 .
