The “invention” is a unique device that has but one relevant purpose and that is to engage both regular and large mouthed mason jars that have been vacuum sealed with a “dome lid” (without a ring), thus attached by a user screwing the invention's two tiered body onto the selected mason jar. The top tier of the invention receives a regular mouthed mason jar while the lower tier receives a large mouthed mason jar. Once screwed onto the existing jar the user depresses the appropriate level leaf spring, thus inserting the associated lifting pin underneath the lip of the present dome lid and then, while holding the mechanism inward, the user unscrews the invention's body causing a counterclockwise and upward force on the dome lid via the lifting pin separating the dome lid from the mason jar, opening it. |
