by | Jun 30, 2023 | Articles


In the world of cosmetics packaging, the specifications of bottle necks play a crucial role. They determine the compatibility of bottles with various closures, pumps, sprayers, and dispensing mechanisms. While there are several commonly used bottle neck specifications such as 15/415, 18/410, 20/410, 24/410, and 28/410, it’s worth noting that non-standard specifications also exist. One notable example is the 32mm snap-on closure, which caters to specific applications. This article delves into the significance of bottle neck specifications and explores both the common and non-standard options available.

Common Bottle Neck Specifications

A. 15/415

The 15/415 bottle neck specification features a 15mm outer diameter and a 415 thread count. This specification is widely used in the cosmetics industry, particularly for smaller-sized products such as lip balms, sample vials, and travel-sized containers. Its compatibility with various closures and dispensers makes it a popular choice for manufacturers seeking versatility in packaging options.

B. 18/410

With an 18mm outer diameter and a 410 thread count, the 18/410 bottle neck specification offers a slightly wider opening. This specification is commonly employed for products like lotion bottles, toners, and serums. The larger opening allows for easier dispensing and the attachment of different types of closures, including pumps and sprayers.

C. 20/410

Featuring a 20mm outer diameter and a 410 thread count, the 20/410 bottle neck specification strikes a balance between size and functionality. It is often utilized for packaging skincare creams, shampoos, and conditioners. The 20/410 specification provides a comfortable grip for consumers and facilitates smooth product dispensing.

D. 24/410

Designed with a 24mm outer diameter and a 410 thread count, the 24/410 bottle neck specification is commonly used for larger-sized cosmetic products such as body lotions, shower gels, and hair masks. Its wider opening enables efficient product flow and allows for the attachment of various closure types, including disc caps and flip-top lids.

E. 28/410

The 28/410 bottle neck specification features a 28mm outer diameter and a 410 thread count. It is often employed for packaging products that require greater product flow, such as body washes and shampoos. The larger neck size allows for the use of pumps and sprayers, enabling controlled and convenient product application.

Non-Standard Bottle Neck Specifications

In addition to the commonly used bottle neck specifications, the cosmetics industry also embraces non-standard options to meet specific requirements. One such example is the 32mm snap-on closure. Unlike the threaded necks, this closure utilizes a unique snap-on mechanism. It offers easy opening and closing functionality and is often paired with specific nozzle or spray heads, providing precise and targeted product application.

While non-standard bottle neck specifications like the 32mm snap-on closure offer unique advantages for specific applications, it’s important to note that they may limit compatibility with a wider range of closures and dispensers. Manufacturers and consumers should be aware of these limitations when selecting packaging options.

While common specifications like 15/415, 18/410, 20/410, 24/410, and 28/410 provide versatile options for various products, non-standard specifications like the 32mm snap-on closure cater to specific needs. Manufacturers and consumers should carefully consider the desired functionality and compatibility requirements when selecting bottle neck specifications for their cosmetic products. By understanding the available options, the cosmetics industry can continue to innovate and provide packaging solutions that meet the diverse needs of consumers.
