Description

Air pressure adjusting accessory of feeding bottle and method for allowing feeding bottle with nipple to feed

Technical Field

The present invention relates to a feeding bottle air pressure adjusting accessory and a method for allowing feeding of a feeding bottle with a nipple, so that when liquid in the feeding bottle flows out, the air pressure adjusting accessory can be adjusted to make the pressure in the feeding bottle consistent with the pressure outside the feeding bottle.

Background

Feeding bottles are commonly used for feeding infants, and the feeding bottles can be used for feeding formula milk instead of feeding breast milk directly, or can still feed the infants with pre-stored breast milk when mothers are not present, or can be used for feeding liquid except the breast milk, such as water or fruit juice.

However, when the liquid in the nursing bottle is sucked out, air should flow into the bottle or the nursing bottle should be capable of being deformed telescopically so that the pressure inside and outside the bottle can be kept the same, otherwise, the liquid in the bottle is more and more difficult to suck out under the condition that the pressure difference between the inside and the outside of the bottle is gradually increased. In general, when an infant sucks in liquid in the bottle, external air enters the bottle from the nipple through the mouth of the infant due to the pressure difference between the inside and the outside of the bottle, so that the infant swallows the air, and the infant vomits milk, flatulence and stomachache, ear infection and the like are caused.

In order to prevent the infant from swallowing air, the nursing bottle may be made to be air-permeable or telescopically deformable.

A milk bottle brand Joovy BOOB was manufactured using a bottle made of CleanLow^TMA vent ring made by the company, the vent ring can be arranged on the bottle mouth, the nipple is locked back to the bottle body after the vent ring is arranged, the vent ring is provided with a silica gel ring arranged on the inner side of the bottle body, the silica gel ring is provided with four equidistant holes, the silica gel ring is fixed with a hard plastic ring arranged on the bottle mouth, and the clearflow is low^TMThe vent ring is notched to allow it to fit the larger neck of a Boob brand bottle to avoid over-tightening or over-loosening, reduce leakage and maintain a constant gas flow rate. However CleanLow^TMThe vent ring of (1) is only suitable for mounting on Joovy BOOB brand milk bottles.

The dr, brown brand nursing bottle is provided with a vent hole in the bottle body, so that air bubbles can be guided to the rear part of the bottle body when an infant sucks the nursing bottle, but liquid can leak from the vent hole under the condition that the nursing bottle is not taken, and the dr, brown brand nursing bottle is also provided with two additional parts, so that the structure is complicated, and the assembly, disassembly and cleaning are inconvenient.

The Comotomo and Minbie brand milk bottles are provided with two vent holes at the bottom of a nipple, while tommeetipee brand milk bottles are provided with one vent hole at the nipple, but in these milk bottles provided with vent holes, the vent holes may be covered by cheeks or clappers to reduce the efficiency of air circulation, and even in tommeetipee milk bottles, the vent holes are not vented at all.

The Philips Avent brand bottle is provided with a pair of air valves that allow venting through a slit located away from the nipple.

The MAM brand anti-flatulence feeding bottle is provided with a vent hole on a base, the brand feeding bottle is provided with a nipple, a nipple ring, a bottle body and a vent base, the vent base is firstly screwed on the bottom of the bottle body during assembly, then the nipple is placed on the bottle body, and finally the nipple ring is sleeved outside the nipple and is locked on the bottle body.

Other feeding bottles with vent holes on the base are also Playtex brand feeding bottles.

The Munchkin Latch brand nursing bottle is provided with an air valve at the bottom of the bottle body to replace an air vent for ventilation.

The Flipsi Natural brand milk bottle has a cup-shaped silicone reservoir which can be used to contain milk and placed into the bottle, after which the nipple is screwed onto the body of the bottle. The storage container is arranged at the upper end of the bottle body, so that a very good sealing effect can be formed after the nipple is screwed, and the size of the storage container made of silicon rubber is matched with the bottle body, so that the storage container can be reduced along with the reduction of milk in the bottle.

The BIBIGO bottle has bellows-shaped side edges to enable the bottle to be flexible and deformable, so that when liquid in the bottle is sucked out, the bottle body can be condensed along with the bellows-shaped side edges to reduce the air volume in the bottle, and the flatulence and abdominal pain caused by the fact that an infant swallows air can be effectively avoided.

The inventor therefore believes that it would be desirable to provide a venting feature which is simple to use, reliable in venting, leak proof and suitable for use with various brands of feeding bottles.

In view of the above drawbacks, the inventor of the present invention considers that there is a need for correction, and then develops the air pressure adjusting accessory of the feeding bottle of the present invention after continuous efforts, based on years of experience in related technologies and product design and manufacture, while keeping the design concept of the product in good order, so as to correct the structure of the product and improve the effect of the product.

In all embodiments, none of the slots 1315 correspond to slots 1325 (i.e., slots 1315 are offset from slots 1325.

Referring to fig. 12, fig. 12 is a partial side view of the adjustment assembly 1300, wherein the groove 1315 is formed at the bottom of the ring 1310, the cross-sectional shape of the groove 1315 is rectangular, the width of the groove 1315 is 1-5 mm, and the height of the groove 1315 is 1-3 mm.

Referring to fig. 13, fig. 13 is a perspective view of a portion of the adjustment fitting 1300, wherein the collar 1310 projects outwardly relative to the cylindrical portion 1320, and the bottom 1312 of the collar 1310 is located on the rim of the bottle body when in use, and the groove 1315 is cut into the bottom 1312, in this exemplary embodiment, the two sides 1317 of the groove 1315 are perpendicular to the outer circumferential surface 1311 of the collar 1310, and the groove 1315 is rectangular.

Referring to fig. 13, which illustrates the path of the air 2000B from outside the adjustment fitting 1300 into the bottle, the air 2000B, after entering the space between the cap and the bottle (the cap and the bottle are not shown in fig. 13), passes through the groove 1315 of the ring 1310, and then enters the bottle through two paths, one of which enters the space between the cylindrical portion 1320 and the bottle through the bottom of the cylindrical portion 1320, and the other of which enters the bottle through the slit 1325 after reaching the slit 1325 from the space between the cylindrical portion 1320 and the bottle.

In some embodiments, at least one groove side 1317 of groove 1315 is disposed non-perpendicular to outer race face 1311 of collar 1310.

The collar 1310 may comprise a rigid and biocompatible material such as, but not limited to, polycarbonate (polycarbonate), polyethylene (polyethylene), and polypropylene (polypropylene), while the cylindrical portion 1320 may comprise a soft elastomeric material such as silicone (silicone).

Preferably, the cylindrical portion 1320 is made of at least one hydrophobic material.

Preferably, the ring 1310 is made of at least one hydrophobic material.

Referring to fig. 8, it can be seen from fig. 8 that the cylindrical portion 1320 made of soft elastic material can extend upward beyond the bottom of the ring 1310.

When the ring 1310 is made of a hard material, the groove 1315 is prevented from being deformed by pressure when the cap 1200 is locked to the bottle 1000.

When the cylindrical portion 1320 is made of a soft elastic material, the edge of the slit 1325 is allowed to shift and swing to prevent the slit 1325 from being blocked when the baby bottle is sucked, which is also advantageous for mounting the adjustment fitting 1300 before use and detaching the adjustment fitting 1300 from the bottle body 1000 after use.

Referring also to fig. 9, the angle of the slit 1325 in the thickness direction represents that the thickness of the slit 1325 is thicker than if the slit 1325 were to cut perpendicular through the cylindrical portion 1320, and a thicker slit 1325 may allow air to pass while still minimizing the possibility of liquid leakage from the cylindrical portion 1320, and a thicker slit 1325 may also represent that the width of the slit 1325 may be larger to increase the amount of air that may enter the bottle 1000 through the slit 1325.

It can also be seen from FIG. 8 that the grooves 1315 are in communication with the space above the threads, thereby allowing air to flow through the grooves 1315 while also helping to reduce the likelihood of liquid leaking from the bottle 1000 by the threads of the bottle 1000 and cap 1200.

The groove 1315 is located on the rim of the bottle body 1000, so that when the bottle body 1000 is placed in a normal state with the bottle mouth facing upwards, the liquid in the bottle body 1000 is lower than the groove 1315 to prevent the liquid from leaking, and compared with the conventional nursing bottle with a vent hole or air valve at the bottom, the weight of the liquid in the conventional nursing bottle with a vent hole or air valve at the bottom may cause the vent hole or air valve to open and the liquid to leak out.

Also, in the embodiment of the present invention, the ring of the air pressure adjustment accessory for a nursing bottle may have a bottom side, a top side, an inner side and an outer side, the bottom side of the ring being flat, at least a portion of the bottom side of the ring being disposed on the rim of the body of the nursing bottle, the ring including at least one groove disposed on the bottom side of the ring, the outer edge of the groove being located on the outer side of the ring, and the groove not extending to the inner side of the ring;
