Description

Nipple and container

Technical Field

The utility model relates to the field of daily necessities, in particular to a nipple and a container.

Background

The suction tube on the nipple of the existing baby bottle can be divided into a through hole type suction tube and a diaphragm type suction tube. The through hole type suction pipe is in a normally open state. In the case where the baby bottle is inverted or shaken, the liquid in the baby bottle is easily leaked out, thereby causing a contamination event. In addition, other people need to invert the bottle to make the liquid flow out, so as to ensure that the infant can drink the liquid in the bottle. However, the through hole has a larger inner diameter, so that the infant is easy to be choked with water after the feeding bottle is inverted.

For a diaphragm type suction tube, a flat diaphragm is provided on the suction tube port. The diaphragm is provided with slits, and the slits in the flat-plate diaphragm are opposite to each other in the positive direction. After the suction pipe is bitten by an infant, the flat plate type diaphragm which is perpendicular to the axis of the suction pipe can provide a remarkable blocking effect on the deformation of the suction pipe, so that the infant needs to provide a large biting force to open the cutting seam to form an opening. This is not conducive to easy drinking of water, milk, etc. by infants.

To overcome this problem, some manufacturers have reduced the thickness of the diaphragm, thereby ensuring that it is more susceptible to deformation. However, the more deformable diaphragm means that the bottle is prone to leakage after being tilted and inverted.

There is therefore a need for a teat which is retrofitted to existing teats.

Fig. 1-2 illustrate perspective views of a nipple 100 according to a first embodiment of the present disclosure, wherein fig. 1, 2 illustrate the nipple 100 from different perspectives. As shown in fig. 1 and 2, the nipple 100 of this embodiment includes a main body portion 110 and a straw portion 120. The main body portion 110 is configured as a thin-walled member having an arcuate surface. The straw portion 120 is an elastic member and extends inside the main body portion 110 from below to above to the outside of the top of the main body portion 110 in the longitudinal direction of the nipple 100 to form a mouthpiece portion S that contacts the mouth of the user. The exposed nozzle portion S and the body portion 110 may be integrally formed. In order to attract the drinking interest of the infant, the main body 110 and the mouthpiece portion S of the teat 100 are formed in a shape substantially corresponding to the shape of the breast.

The nipple 100 may be formed in one piece from a food grade silicone material, for example.

Fig. 3 illustrates a cross-sectional view of a nipple 100 according to a first embodiment of the present disclosure. Referring to fig. 3 in conjunction with fig. 1, the top of the mouthpiece portion S of the nipple 100 is formed with a diaphragm portion capable of closing the straw portion 120. In this embodiment, the diaphragm portion 122A is formed specifically on the top surface of the straw portion 120. The diaphragm portion 122A is in an exposed visible state. The diaphragm portion is formed with a cross-shaped slit 124 as shown in fig. 1 or other slits 124, such as a plurality of slits 124 that are staggered in a crisscross manner. In a natural state where the nozzle portion S is not deformed, the opposite surfaces of the respective slits 124 are attached to each other, thereby sealing the top of the straw part 120.

It should be noted here that the "top" of the straw portion 120 may be expressed as any portion of the straw portion 120 protruding from the top surface of the main body portion 110.

With continued reference to fig. 1 and 3, unlike the prior art, according to the nipple 100 of the present disclosure, the diaphragm portion 122A in the straw portion 120 is no longer in the form of a flat plate, but is recessed toward the inside of the main body portion 110. The flat diaphragm portion 122A is strong against a lateral force (radial force). When a lateral pressure (a force perpendicular to the thickness direction of the diaphragm portion 122A) is applied to the diaphragm portion 122A, the diaphragm portion 122A is less likely to deform. Since the diaphragm portion in the present disclosure is provided in a concave form, the ability of the diaphragm portion 122A to resist lateral forces is significantly reduced. This form of teat 100 is particularly suitable for infants who are just beginning to wean or other infants with a low level of biting force.

The inward concave diaphragm portion 122A becomes increasingly concave with the deformation of the straw when the straw portion 120 is occluded, so that the slit 124 of the diaphragm portion 122A is deformed to create a small opening. In the case where the baby bottle is found to be inclined or inverted, the direction of the impact force of the liquid inside the baby bottle on the diaphragm portion 122A is obviously opposite to the direction of the concavity, so that the liquid cannot aggravate the degree of concavity of the diaphragm portion 122A; in addition, the impact force is not enough to deform the membrane portion 122A, which is concave, to be convex, and further, the membrane portion 122A continues to deform after being convex to form the opening. Therefore, the membrane portion 122A of concave form, even with a small thickness, can prevent the milk bottle from leaking out due to the impact of the liquid in the bottle.

With continued reference to fig. 1 and 3, a lower portion of the main body portion 110 of the nipple 100 may be provided with a laterally outwardly projecting annular flange portion 112. When the baby bottle is mounted on the opening of the baby bottle, the annular flange portion 112 abuts on the opening rim of the baby bottle, and then the cap member 210 (described later) can firmly press-fix the nipple 100 on the baby bottle through the annular flange portion 112. This form of teat 100 can be easily mounted and secured.

The main body portion 110 of the nipple 100 forms an annular groove 116 that is laterally recessed adjacent an upper side of the annular flange portion 112. Preferably, at least one positioning portion 118 protruding outward is formed along the circumferential direction of the annular groove 116, wherein a pair of positioning portions 118 opposite in the radial direction are provided in the embodiment of fig. 1.

The cap member 210 (screw cap) presses the nipple 100 against the opening of the baby bottle while the radially inner edge of the cap member 210 abuts just against the annular groove 116 and is locked by the positioning portion 118. This makes relative rotation between the teat 100 and the cap member 210 less likely.

The number of the positioning portions 118 is only two in fig. 1, and in fact, any number of the positioning portions 118 may be provided, such as 1, 3, or 4. Furthermore, the detent 118 of fig. 1 is shown in cylindrical form, which may be replaced with other cylindrical forms.

At least one air return valve 114 is formed on the annular flange portion 112 of the nipple 100. The air return valve 114 may be a V-shape with the opening facing upward. The air return valve 114 can ensure the pressure balance between the inside and the outside of the feeding bottle, and prevent the low pressure inside the feeding bottle from affecting the discharge of liquid after the liquid in the feeding bottle is sucked away by the infant.

Referring to fig. 1, to prevent the cover member 210 from obstructing the air return valve 114, the positions of the air return valve 114 and the annular flange portion 112 that engage the member are offset from each other. For ease of manufacture, the main body portion 110 is provided with an escape slot 115 longitudinally (axially) aligned with the air return valve 114. For the integrally formed nipple 100, the mold may be sequentially passed through the above-mentioned relief groove 115 of the main body 110 to the position of the air return valve 114, thereby achieving the purpose of simple manufacture.

In order to further simplify the manufacturing process, as shown in fig. 4, the air return valve 114 and the positioning portion 118 of the present invention are staggered from each other.

The diaphragm portion 122A of the present embodiment is preferably concave in an arc shape, and the radius of curvature of the arc shape may be set to any value of 1mm to 3mm, for example, 1.5mm, 2mm, 2.5mm, or the like.

The thickness of the diaphragm portion 122A may be set to any value of 0.8mm to 2mm, for example, 1mm, 1.2mm, 1.5mm, or the like. The membrane portion 122A is made of food grade conventional silica gel.

Referring to fig. 4, a container according to the present disclosure is shown provided with a nipple 100 as shown in fig. 1-3. As shown in fig. 4, the container includes a nipple 100, a body 200, a cap member 210, and the like. Wherein the body 200 has an opening at the top for engaging the nipple 100. The opening is provided with an external thread part, and a sleeve gasket 230 for anti-friction can be selectively arranged below the bottle body 200. The sleeve gasket 230 may be secured to the body 200 by threaded engagement, gluing, or the like.

The cover member 210 is a member of a cylindrical form penetrating vertically. The lower opening of the cover member 210 has a size larger than the upper opening thereof. The upper opening is formed by a vertical wall of the cover member 210 being bent laterally (radially) inwardly, so that the upper opening defines an inner edge 212 of the cover member 210. The lower opening of the member 210 is formed with an internal thread portion which is engaged with the external thread portion at the opening of the body 200. In addition to the threaded engagement, other engagement means such as snap fit may be used between the cap member 210 and the bottle body 200 to lock the nipple 100 to the bottle body 200, and will not be described herein.

With continued reference to fig. 1 and 4, an interior recess 214 is formed on the interior side of the inner rim 212 of the cover member 210 to form fit with the detent 118. In use, the teat 100 may be inserted through the lower opening of the cap member 210 until the mouthpiece portion S of the teat 100 is inserted through the upper opening of the cap member 210. Before screwing the cap member 210 to the bottle body 200, the cap member 210 and the nipple 100 should be aligned with each other such that the concave portion 214 of the cap member 210 and the positioning portion 118 of the nipple 100 are fitted into each other. After alignment, cap member 210 is then screwed onto body 200.

As shown in fig. 4, the container may also be provided with a handle member 220 to facilitate gripping by the infant. Wherein the handle member 220 has a ring portion as part of the main body portion 110, and two handle portions 222 extending downwardly from the ring portion. The handle member 220 is fixed between the cover member 210 and the body 200.

Referring to the cross-sectional view of the container shown in fig. 5, in a preferred embodiment, the container further includes a weight mechanism 300 removably secured to a lower portion of the straw portion 120. The weight mechanism 300 has a density greater than that of water, and is formed with a through hole fluidly connected with the straw part 120. In the natural state, the weight mechanism 300 naturally hangs down so that the infant can drink the liquid in the container in the natural resting state of the container as shown in fig. 5.

According to the present embodiment, the weight mechanism 300 is composed of the connection member 310 located at the upper portion, the gravity body 330 located at the lower portion, the connection pipe 320 connecting the connection member 310 and the gravity body 330, and the like. The connector 310 is detachably fixed to the lower end of the straw part 120.

Preferably, as shown in fig. 3 and 5, the inner surface of the lower portion of the straw portion 120 is formed with an annular protrusion 126. Correspondingly, the upper portion of the connecting member 310 is formed with a laterally inwardly recessed annular stop portion 312. The annular stopper portion 312 is formed as a groove that mates with the annular protrusion 126. When the connector 310 is inserted into the lower portion of the straw portion 120, the annular stopper 312 is caught in the annular groove 116, which ensures that the weight mechanism 300 is not easily detached from the straw portion 120.

In order to prevent the liquid from leaking out when the straw 120 is accidentally pressed by the outside in the case where the container is inverted, the container further includes a cap 240 as shown in fig. 4 and 5. The closure 240 may close the teat 100 on the body 200.

As a preferred embodiment, the inner wall surface of the cap 240 is provided with a stopper wall 240 that is form-fitted to the nipple 100 at a position corresponding to the top of the straw portion 120 of the nipple 100. After the cap 240 is caught on the bottle body 200 (the cap member 210), the stopper wall 240 surrounds the mouthpiece portion S of the pacifier 100, which may prevent the mouthpiece portion S from shaking.

In the above embodiment, the weight mechanism 300 is provided in the container, however, the weight mechanism 300 is not an essential component of the container. For example, in another embodiment, not shown, the lower end surface of the straw portion 120 is disposed to abut the bottom of the container. It will be appreciated that the container of this embodiment also meets the drinking needs of infants and young children.

Referring to another preferred embodiment according to the present disclosure shown in fig. 6-8, in this embodiment, the position and shape of the diaphragm portions 122A, 122B of the straw portion 120 are different from the diaphragm portions 122A, 122B in fig. 1-5. For the remainder, this can be understood in conjunction with the text above with respect to fig. 1-5, and therefore will not be described in detail. Only the diaphragm portions 122A and 122B of this embodiment will be described below.

Unlike the diaphragm portion 122A in fig. 1 to 5, the diaphragm portion 122B of this embodiment is not provided on the top surface of the straw portion 120, but is provided at a position at a distance from the upper surface of the straw portion 120. Specifically, referring to fig. 8, the distance between the upper surface of the diaphragm portion 122B and the upper surface of the straw portion 120 is set at any value in the interval of 6mm to 10mm, for example, 7mm, 8mm, 9mm, or the like.

In addition, the degree of concavity of the diaphragm portion 122B in this embodiment is more pronounced than the diaphragm portion 122A of the embodiment of FIGS. 1-5. Specifically, the radius of curvature of the diaphragm portions 122A, 122B in the arc-shaped configuration in the embodiment of fig. 6-8 is set to any value of 4mm-6mm, for example, 4.5mm, 5mm, 5.5mm, or the like.

Further, the straw part 120 of the nipple 100 in this embodiment is formed in a streamline form gradually expanding outward from the bottom to the top, which can increase the aesthetic feeling while ensuring the oral cavity-inhaling comfortable feeling during the use of the infant.

Finally, it should be noted that: although the present disclosure has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes, modifications, equivalents, and improvements may be made without departing from the spirit and scope of the disclosure.
