Description

Technical Field

[0001] This utility model belongs to the field of packaging bottle technology, specifically relating to a baby cream / lotion packaging bottle. Background Technology

[0002] The packaging design of infant care products such as baby creams and lotions needs to balance safety, convenience, and hygiene. Currently, most baby cream and lotion bottles on the market use a press-type structure, which works by squeezing the liquid inside the bottle through a pump head, causing it to spray out from the outlet. However, this traditional press-type packaging has significant drawbacks in practical use:

[0003] During operation, users need to press the pump head with one hand while tilting and maintaining a specific angle with the other to catch the lotion at the outlet. Because the lotion is liquid, the force and direction of the spray are difficult to control. Users must simultaneously ensure their palm is flat to avoid splashing and adjust the angle to prevent overflow, making coordination difficult. This is especially true for parents caring for infants, who often need to operate with one hand (e.g., holding the baby with the other). In such cases, the inconvenience of traditional pump-type packaging is even more pronounced, resulting in cumbersome operation, low efficiency, and easy waste of lotion.

[0004] Existing technologies for pump-type packaging primarily focus on improving the sealing of the pump head structure or designing for easier pressing, but they have not effectively addressed the core issues of inconvenient one-handed operation and liquid splash control. Therefore, there is an urgent need for a new type of baby cream / lotion packaging bottle that enables convenient one-handed operation and precise control of lotion flow to enhance user experience and meet practical usage needs. Utility Model Content

[0005] The purpose of this invention is to provide a baby cream / lotion packaging bottle to solve the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a baby cream / lotion packaging bottle, comprising a bottle body and a straw mechanism threaded onto the bottle body; the straw mechanism includes a shell, a pressure block, an elastic capsule, a limiting plate, and a straw; the upper part of the shell has a through hole, through which the pressure block passes, and the lower diameter of the pressure block is larger than its upper diameter and the diameter of the through hole, so that the pressure block is engaged in the shell; the elastic capsule is located inside the shell, and its upper part is embedded in the arc-shaped limiting groove at the bottom of the pressure block; the lower part of the elastic capsule is connected to the straw, and the bottom of the straw is connected to a rubber hose; the limiting plate is set at the lower part of the elastic capsule, and the straw passes through the through hole in the middle of the limiting plate, the inner wall of the through hole is provided with a double-layer sealing ring, and the straw is sealed with the double-layer sealing ring; the limiting plate is provided with an external thread around its circumference, and the bottom of the shell is provided with an internal thread, and the two are threadedly engaged. The combination of the pressure block and the elastic capsule allows for single-handed pressing to absorb and release the emulsion, avoiding the inconvenience of traditional press-type emulsions that require both hands to tilt and receive. The double-layer sealing ring and threaded fit improve the sealing performance and prevent the emulsion from contaminating the internal structure. The rubber hose can suck up the emulsion at the bottom of the bottle, reducing waste.

[0007] Preferably, the elastic capsule is made of elastic rubber material and has a vertically placed elliptical structure. The elastic rubber material ensures that the capsule quickly recovers its shape, and the elliptical structure provides a stable compression space, facilitating efficient adsorption and storage of emulsion. The vertical placement is ergonomic and makes pressing easier.

[0008] Preferably, the bottom of the limiting plate is provided with four tool slots for tightening the limiting plate with a special tool. The tool slot design facilitates the precise installation of the limiting plate with a special tool, improves assembly efficiency, avoids slippage or overtightening caused by manual operation, and ensures the thread fit accuracy between the limiting plate and the outer shell.

[0009] Preferably, the inner wall of the outer shell is provided with a limiting protrusion, which abuts against the limiting protrusion when the limiting plate is screwed in. The limiting protrusion restricts the screwing depth of the limiting plate, preventing excessive screwing that could cause deformation of the elastic capsule or straw, ensuring accurate positioning of each component and maintaining stable operation of the mechanism.

[0010] Preferably, an O-ring is provided on the upper part of the limiting plate, and the O-ring contacts and seals with the lower part of the limiting protrusion. The O-ring forms a flexible seal between the limiting plate and the limiting protrusion, filling the threaded gaps, effectively preventing emulsion from seeping into the shell, avoiding contamination of the elastic capsule, and improving the hygiene and sealing of the packaging bottle.

[0011] Preferably, the straw is made of glass, and the rubber tubing is used to absorb the emulsion at the bottom of the bottle. The glass straw is stable and corrosion-resistant, preventing chemical reactions with the emulsion and ensuring product safety; the rubber tubing is flexible and can be bent to fit the bottom of the bottle, ensuring that the emulsion inside is completely absorbed, improving utilization.

[0012] The beneficial effects of this utility model are as follows: This utility model, through the linkage structure of the elastic capsule and the pressure block, allows users to complete the entire process of "pressing to expel air → releasing to absorb emulsion → pressing to release emulsion" with one hand. Specifically: when absorbing emulsion, hold the outer shell with one hand and press / release the pressure block. The elastic capsule (elliptical rubber material with strong resilience) automatically draws the emulsion from the bottle through the straw and rubber hose, without the need for the other hand to assist in tilting or blocking; when releasing emulsion, remove the straw mechanism and press the pressure block with one hand to precisely control the emulsion flow, avoiding the hand contamination problem caused by liquid spraying in traditional press-type nozzles, which is especially suitable for parents to operate when holding a baby with one hand. Through mechanical structural innovation, this patent is significantly superior to existing technologies in terms of ease of operation, emulsion utilization rate, hygiene and safety, and durability, providing an efficient, convenient, and reliable solution for baby cream and lotion packaging.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings and preferred embodiments.

[0022] like Figure 1 and Figure 2 As shown, a baby cream / lotion packaging bottle includes a bottle body 1 and a straw mechanism 2 threadedly connected to the bottle body. The bottle body can be a common bottle body. The straw mechanism 2 includes a shell 21, a pressing block 22, an elastic capsule 23, a limiting plate 24, and a straw 25. The upper part of the shell has a through hole through which the pressing block passes. The lower part of the pressing block is located inside the shell, and the diameter of the lower part of the pressing block is larger than the diameter of the upper part of the pressing block and the through hole, so that the pressing block can be stuck in the shell. The elastic capsule is located inside the shell. The elastic capsule is made of a rubber material with good elasticity and can quickly recover. It has an elliptical structure and is placed vertically. In order to limit the elastic capsule, the bottom of the pressing block has an arc-shaped limiting groove, and the upper part of the elastic capsule is embedded in the limiting groove.

[0023] like Figure 2 As shown, the lower part of the elastic capsule is connected to the straw, which is made of glass (resistant to chemical corrosion). The bottom of the straw is connected to a rubber hose 26 to facilitate the suction of the emulsion from the bottom of the bottle.

[0024] like Figure 3-5 As shown, in order to position the elastic capsule and the straw, a limiting plate is provided at the lower part of the elastic capsule, and the straw passes through the through hole in the middle of the limiting plate. Furthermore, in order to prevent the emulsion from flowing into the upper shell from between the through hole and the straw and contaminating the elastic capsule, a double sealing ring 241 is provided on the inner wall of the through hole, and the straw passes through the double sealing ring, forming a seal between the two. The limiting plate has external threads around its circumference, while the bottom of the outer shell has internal threads. The threads of the two are engaged. To facilitate screwing the limiting plate into the outer shell, four tool slots 242 are provided at the bottom of the limiting plate. A special tool is used to hold the limiting plate in the tool slots and screw it into the bottom of the outer shell. Furthermore, to prevent it from being screwed in too deeply, a limiting protrusion 27 is provided on the inner wall of the outer shell. The limiting plate stops when it reaches the position of the limiting protrusion. Furthermore, to prevent emulsion from entering the upper part of the outer shell through the threaded gaps, an O-ring 243 is provided on the upper part of the limiting plate. When the limiting plate is screwed in, the O-ring contacts the lower part of the limiting protrusion and deforms to fill and seal the gap between them.

[0025] The assembly method is as follows: First, embed the upper part of the elastic capsule 23 into the limiting groove at the bottom of the pressure block 22 to ensure a tight fit. When the pressure block is pressed, the elastic capsule can be compressed evenly.

[0026] Next, pass the straw 25 through the through hole of the limiting plate 24, and use the double sealing ring 241 to achieve a sealed connection between the straw and the limiting plate; use a special tool (such as a wrench with a protrusion) to hold the tool groove 242 at the bottom of the limiting plate, and screw the external thread of the limiting plate 24 into the internal thread of the outer shell 21 until the O-ring 243 on the upper part of the limiting plate contacts and compresses the limiting protrusion 27 on the inner wall of the outer shell to form a seal (as shown in Figure 3).

[0027] Finally, the lower end of the outer shell 21 is connected to the external thread at the top of the bottle body 1 by a threaded connection, ensuring that the straw mechanism is securely installed on the bottle body, and the rubber hose 26 hangs down naturally to the bottom of the bottle body.

[0028] Usage process

[0029] 1. Absorbing the emulsion (filling process)

[0030] Hold the outer shell 21 with one hand and press down on the pressure block 22 with your thumb. The pressure block pushes the elastic capsule 23 to compress and expel the internal air (as shown in Figure 2).

[0031] When the pressure block 22 is released, the elastic capsule 23 automatically returns to its elliptical shape due to the elasticity of the rubber, creating a negative pressure inside. The emulsion at the bottom of the bottle 1 is drawn into the elastic capsule through the straw 25 and the rubber hose 26 (the rubber hose can be bent to fit the bottom of the bottle, ensuring that the remaining emulsion is fully absorbed).

[0032] Once the elastic capsule has fully recovered, it is filled with lotion, completing the filling process.

[0033] 2. Release the emulsion (during application)

[0034] Loosen the outer casing 21 and remove the straw mechanism 2 from the bottle body 1 (while maintaining the sealed connection between the limiting plate and the outer casing).

[0035] Hold the outer shell 21 with your right hand and press the pressure block 22 with your thumb. The elastic capsule 23 is compressed, and the emulsion is slowly squeezed out from the outlet of the straw 25 (as shown in Figure 4).

[0036] The left hand can directly catch the lotion under the straw without tilting or blocking the outlet, thus avoiding lotion splashing and contaminating the palm.

[0037] Tests showed that the packaging bottle provided in this embodiment can be operated with one hand to dispense liquid, with a single press dispensing volume of 1.5-2 mL and a residual volume at the bottom of the bottle of less than 3%; the sealing structure does not leak when tilted or inverted, and the elastic capsule (23) did not show permanent deformation after 5000 press tests.

[0038] This specific embodiment fully realizes the technical solution of this patent through structural optimization and precision assembly, and has the advantages of practicality, reliability and ease of use. It can be widely used in the field of baby care products.

[0039] It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
