How to select the appropriate wide-mouth cream jar based on the size of the bottle's neck?
In the beauty and cosmetics industry, wide-mouth cream jar are almost a standard packaging. Face creams, exfoliating creams, body lotions, bath salts and other products all rely on them. However, when choosing a bottle, many people often only focus on the capacity and appearance, but overlook a key point that directly affects the usage experience and product compatibility - the size of the bottle mouth.
In fact, the size of the bottle mouth of a wide-mouth cream jar can be judged by one indicator:Neck size specification
Neck size specification： usually refers to the outer diameter size of the bottle mouth's thread, and is measured in millimeters (mm).
In the industry, 33 teeth, 48 teeth, 58 teeth, 68 teeth, and 89 teeth are basically equivalent to the outer diameter size of the bottle mouth's thread, with an error generally not exceeding 0.5mm.
1,The larger the neck size, the larger the bottle mouth.
Common neck size specification: The common teeth size for wide-mouth cream jar is generally 48 teeth or above, including:
48 teeth / 58 teeth / 68 teeth / 76 teeth / 89 teeth / 108 teeth
Two practical judgment methods:
① Precise method (recommended)
Measure the outermost diameter of the bottle mouth thread with a caliper, and the measured value can correspond to the thread specification.
This method is the most reliable for bulk purchasing and sample production before production.
② Simple method (can be used without tools)
Look at the "XX teeth" marked on the bottle body or the drawing, and try to screw in a bottle cap of the known specification. If it can be tightened and does not loosen, it is acceptable.
Experience judgment:
Small capacity is mostly 33/48 teeth
Medium capacity is mostly 58/68 teeth
Large capacity is mostly 76/89 teeth
II. The small bottle mouth and the large bottle mouth can be easily distinguished from each other at a glance.
1. small bottle mouth (33 teeth, 48 teeth / 58 teeth): Better Sealing
The bottle opening is smaller, and its greatest advantage is excellent sealing performance, which can effectively reduce evaporation and oxidation. Suitable for delicate cream products such as face cream, hand cream, household cream, sleep mask, etc. Common capacity: 15–50ml. It is used for trial packs, portable packs, and can be used with fingers to control the dosage, which is convenient.
Minor reminder:
Filling is relatively inconvenient and usually requires the use of special filling tools.
2.large bottle mouth (68 teeth / 76 teeth / 89 teeth): Easier to use
The bottle mouth is larger, making filling and taking out easier, especially suitable for products with thick texture or particles. Suitable for products such as body lotions, scrubs, bath salts, Vaseline, etc. with large capacity, thick texture or granular form. Common capacities: 100–500ml. Generally, a spoon is used for taking, to avoid contamination from direct hand contact.
Minor reminder:
The sealing performance is relatively weaker. It is recommended to pair with an inner stopper or a thickened bottle cap structure.
III. Four Common Misunderstandings That Must Be Avoided
1. The larger the bottle opening, the better.
❌ Using a large opening for volatile products actually makes them more prone to oxidation and deterioration.
2. Just look at the size of the bottle mouth, without considering the pitch and the tooth shape.
❌ This can lead to problems such as mismatched bottle caps and leakage.
3. Excessive pursuit of "perfect consistency" in size.
❌ An error of 0.3–0.5mm is the industry norm. Excessive precision will only increase costs.
4. All products have the same bottle opening size..
❌ All the small-sized abrasive pastes are difficult to apply and the experience is simply disastrous.
In summary:When choosing a wide-mouth cream jar , the key lies in the tooth opening: The selection of tooth opening specifications should take into account the product texture, capacity requirements, and usage scenarios to ensure both ease of use and product stability. Whether it's for brand procurement, business product selection, or daily use, you can easily choose the right bottle opening specification.
