What is the function of plastic seasoning bottles with different lids?

      Seasoning is an essential ingredient in our daily lives, and plastic bottles, as one of the most common packaging materials, are equipped with different lids that have a significant impact on the quality and user experience of seasoning. The role played in preservation, convenient use, leak prevention, safe sealing, and beautiful decoration.

1、 Preservation:

The freshness and taste of seasonings are one of the important factors that every consumer is concerned about, and plastic bottles equipped with different lids can effectively maintain the freshness and taste of seasonings.

1.1 Sealing ring:

Some lid designs come with sealing rings, such as rubber or silicone rings, which can effectively seal the bottle mouth and prevent air from entering the bottle, thereby slowing down the oxidation and quality changes of seasonings. A common example is the lids of various soy sauce bottles, which usually come with sealing rings to ensure the freshness and taste of the sauce.

1.2 Gland device:

Another common lid design is with a gland device, such as a threaded or gland cover. By pressing down on the lid, air can be squeezed out of the bottle, achieving an effective preservation effect. For example, many seasoning bottles are equipped with threaded caps. When we add them to the bottle mouth, we only need to gently rotate them to lock the air out of the bottle and maintain the freshness of the seasoning.

2、 Easy to use:

Seasonings are bound to come into contact with food, so their packaging should have a convenient function. Plastic bottles equipped with different lids can better meet the needs of consumers.

2.1 Flip Cover:

Flip lids are a common design used to facilitate the pouring of seasonings. For example, many salt and pepper bottles are equipped with flip caps, which can be gently pressed to pour out the seasoning.

2.2 Fruit Mouth:

Another convenient design is the fruit mouth, also known as the extrusion mouth or spray mouth. This type of lid is usually used for packaging dips or sauces. Simply press down on the lid and the seasoning can be squeezed out through the fruit mouth, making it very convenient.

3、 Leakage prevention:

The leak proof function of seasoning bottles is very important, especially when carried or tilted. Plastic bottles equipped with different lids can effectively prevent seasoning leakage and avoid waste and pollution.

The rotating cover is a common design that is both convenient to use and leak proof. It can tighten the lid by rotating it to ensure that the seasoning does not leak. This design is commonly used in various seasoning sauce bottles, such as tomato sauce, chili sauce, etc.

3.2 Gland cover plate:

The gland cover is a common design that is suitable for most seasoning bottles. The cover plate effectively prevents the leakage of seasoning by pressing it down and inserting it into the bottle mouth. Compared to traditional rotating covers, it is easier to operate.

4、 Safety seal:

The safe sealing of seasoning bottles is crucial for the health of consumers. Plastic bottles equipped with different lids can effectively ensure the safety and sealing of seasonings, avoiding external pollution and bacterial growth.

4.1 Anti counterfeit cover:

The anti-counterfeiting cover is a commonly used design to ensure the safety and sealing of seasonings. This type of lid is commonly used in high-end seasoning bottles, such as premium soy sauce and specialty seasonings. By breaking or unscrewing the lid, it can be ensured that the lid has never been opened, preventing the seasoning from being replaced or improperly used.

4.2 Sealing film:

Sealing film is a common safety sealing design that ensures that seasonings are not contaminated during production, transportation, and sales by attaching the film to the bottle mouth. Consumers can judge whether the product is safe by the integrity of the membrane when making a purchase.

5、 Beautiful decoration:

In addition to functionality, plastic bottles equipped with different lids can also enhance the aesthetics of seasoning bottles, enhance the product's image and brand value.
