Description

Pacifiers and bottles Technical Field

[0001] The invention belongs to the technical field of feeding bottles, in particular to a nipple used on a feeding bottle. Background Art

[0002] The nipple is a part of the feeding bottle that allows the baby to suck the milk in the bottle into the mouth.

[0003] In the prior art, pacifiers are made of silicone and appear round when viewed from the front. When babies drink milk, they have to open their mouths into an O-shape to fit the pacifier. Maintaining this mouth shape increases the amount of energy a baby needs to absorb milk.

[0004] Summary of the Invention

[0005] The object of the present invention is to provide a pacifier which is easy to fit into the baby's mouth.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A pacifier includes a body having a head, an expanded diameter portion and a base. The head is connected to the base via the expanded diameter portion. An outer layer is provided on the outside of the body. The outer layer and the body form a closed air cavity. The air cavity extends from the upper part of the expanded diameter portion toward the base.

[0008] On the basis of the above solution and as a preferred solution of the above solution: the air cavity is continuous in the circumferential direction of the main body.

[0009] On the basis of the above solution and as a preferred solution of the above solution: the main body and the outer layer are both made of silicone material.

[0010] On the basis of the above solution and as a preferred solution of the above solution: an annular groove is provided at the connection between the expanded diameter portion and the base portion.

[0011] On the basis of the above solution and as a preferred solution of the above solution: it also includes a vent valve, which passes through the expanded diameter portion and the outer layer.

[0012] On the basis of the above solution and as a preferred solution of the above solution: a vent valve is provided on the expanded diameter portion, and the outer layer avoids the vent valve to expose the vent valve.

[0013] The present invention also discloses a feeding bottle with the above-mentioned nipple, comprising a bottle body, a cap threadedly connected to the top of the bottle body, the base being clamped between the top wall of the cap and the bottle mouth of the bottle body, the hole edge on the top of the cap being embedded in the annular groove, and the head being exposed outside the cap.

[0014] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects:

[0015] The pacifier of this invention utilizes an air cavity structure. When a baby's mouth contacts the outer layer, the air cavity causes the outer layer to deform somewhat during sucking, making it more comfortable for the baby's mouth. Furthermore, as the outer layer deforms and fits the baby's mouth, the gas pressure within the air cavity evenly balances the force applied to the expanded diameter portion corresponding to the cavity, causing the expanded diameter portion to deform, making it easier for the baby to absorb milk.

[0018] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the given embodiments, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0019] In the description of this application, it should be understood that the terms "upper" and "lower" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on this application.

[0020] The present invention discloses a pacifier, comprising a body 1, the body 1 having a head 11, an expanded diameter portion 12 and a base 13, the head 11 being connected to the base 13 via the expanded diameter portion 12, an outer layer 2 being provided on the outside of the body 1, the outer layer 2 and the body 1 forming a closed air cavity 3, the air cavity 3 extending from the upper part of the expanded diameter portion 12 toward the base 13.

[0021] The pacifier of the present invention utilizes an air cavity 3. When a baby's mouth contacts the outer layer 2, the presence of the air cavity 3 causes the outer layer 2 to deform somewhat during sucking, making it more comfortable to fit the baby's mouth. Furthermore, after the outer layer 2 deforms and fits the baby's mouth, the pressure of the gas within the air cavity 3 balances the force applied to the expanded diameter portion 12 corresponding to the air cavity 3, causing the expanded diameter portion 12 to deform as a whole, making it easier for the baby to absorb milk.

[0022] In one embodiment, both the main body 1 and the outer layer 2 are made of silicone. Typically, the thickness of the outer layer 2 is thinner than that of the expanded diameter portion 12. With this structure, the outer layer 2 is less hard than the main body 1. As a result, when an infant's mouth comes into contact with the outer layer 2, the outer layer 2 deforms appropriately, allowing it to conform to the infant's mouth.

[0023] In this embodiment, the air cavity 3 is continuous along the circumference of the body 1. Specifically, the air cavity surrounds the body 1. Alternatively, multiple air cavities 3 may be arranged in a sequential pattern around the circumference of the expanded diameter portion 12. This configuration also ensures that the expanded diameter portion 12 is subjected to uniform force along its circumference.

[0024] As shown in the figure, an annular groove 4 is provided at the connection between the enlarged diameter portion 12 and the base portion 13. In a specific application, the annular groove 4 can be used to assemble the nipple with the cover to prevent the nipple from falling off the cover.

[0025] In this embodiment, the vent valve passes through the enlarged diameter portion 12 and the outer layer 2. As another arrangement structure of the vent valve, the enlarged diameter portion 12 is provided with a vent valve, and the outer layer 2 avoids the vent valve so that the vent valve is exposed.

[0026] The present invention also discloses a feeding bottle using the nipple of the above embodiment, comprising a bottle body, a cap threadedly connected to the top of the bottle body, a base 13 clamped between the top wall of the cap and the bottle mouth of the bottle body, a hole edge on the top of the cap embedded in the annular groove, and a head 11 exposed outside the cap.

[0027] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
