Description

[0001] The utility model relates to the food industry and is aimed at preserving products.

[0002] To create a vacuum lid with a piston that effectively preserves food, you can consider several similar analogs and their features:

[0003] Cover with automatic pump and valve: RU 212534 U1

[0004] Description: The lid is equipped with an automatic pump that is activated by pressing a button and releases air through a valve.

[0005] Advantages: Easy to use, does not require physical effort.

[0006] Disadvantages: More complex design, may require batteries.

[0007] Vacuum lid with electric pump: RU 2073635 C1

[0008] Description: Lid with an electric pump that automatically removes air from the container at the press of a button.

[0009] Advantages: High efficiency, minimal user effort.

[0010] Disadvantages: Higher cost, dependent on power source.

[0011] These analogs offer different approaches to creating a vacuum in food storage containers, each with its own advantages and disadvantages. The closest in technical essence is:

[0012] Vacuum lid with hand pump: Russian patent 2073635

[0013] Description: Lid with a hand pump that allows the user to manually pump air out of the container.

[0014] Advantages: Simple design, no need for springs.

[0015] Disadvantages: Requires a hand pump. Requires physical effort to create a vacuum.

[0016] The vacuum lid with piston is an innovative design designed to create a vacuum and seal containers for long-term storage, and even re-canning after opening and partial consumption. This useful model combines ease of use and versatility, fitting most jar and container sizes, making it an effective solution for home and commercial canning.

[0017] Cover design with piston.

[0018] The center of the lid features a concave chamber containing a valve for releasing air from the container. Inside the concave chamber is a piston cap with its own valve for releasing air from the chamber. The piston cap is raised and lowered using the handle on the lid, alternately releasing air from the chamber and container through the valves, creating a vacuum in the container. To ensure a tight seal, an O-ring seal made of food-grade silicone or another aseptic polymer is used. This seal is located between the lid and the neck of the container, preventing air from entering and maintaining a vacuum. To facilitate lifting the piston cap, a spring can be used or the piston cap can be made corrugated. It is also possible to corrugate the edges of the piston cap along the diameter or perimeter for added convenience.

[0019] The proposed design allows you to easily and effectively create a vacuum in the container, ensuring long-term preservation of food.

[0020] To open a vacuum-sealed lid, simply locate the edge of the valve on the lid and gently lift it upward with your finger. Air will enter the jar with a distinctive sound. Once the vacuum is broken, the lid will easily slide off the jar.

[0021] The vacuum lid with piston is a multifunctional device that, thanks to its unique characteristics and versatility, finds wide application in various fields. It ensures secure storage of food products, as well as paints, solvents, and other liquids, making storage and use more convenient and safe.
