While a primary purpose of the membrane 1132 is to create a safe and reliable vacuum seal, labeling helps too. By sealing, a user looks at permeation or transmission of gases though label. By being thin it can deform and stretch to show sealing effect, thereby indicating the food in the container is still safe to eat. The text artwork can be instructions for opening with the tabs or product branding graphics. A process that prints on the upper membrane can be preprinting the membrane prior to assembly could be hot stamping or pad printing. It can use in mold labeling to place a film insert on a spreadera label that is molded in place making the spreader and label one much as one sees on containers such as butter packaging. The material in this case would need to be one that maintains a seal, thus the coating that one sees on a peanut butter jar or some other layer in the material. In-mold labeling (IML) is a labeling method in which a pre-printed decorative film is placed into a mold before the plastic container is shaped into that mold. Plastic pellets or resin are heated and placed into the mold where it merges with the label to create a single product.

A circular disc 1510 is concentrically fit into a circular top mouth opening 1502 of an inside annular surface 1503 of a container 1501. The circular disc 1510 is sized to be loosely fit into the circular top mouth opening 1502 of the inside annular surface 1503 of the container 1501. The container 1501 has threads 1508 and a threaded screw on lid 1509. An outside perimeter of the circular disc 1510 forms a handle for grasping by fingers of a user.

(66) The circular disc 1510 is a ring that is one large vent hole 1512. The circular disc 1510 is an open ring 1512 with a spreader 1515 integrally formed extending below the open ring 1512. The spreader 1515 is a substantially flat shape and is integrally formed in the same material as the circular disc 1510 and extends downward from the circular disc 1510 to a bottom tip 1516 of the spreader 1515.

(67) An upper outer flanged circular ring 1511 is integrally formed with the circular disc 1510 to prevent the circular disc from press fitting too deeply into the circular top mouth opening 1502.

(68) A lower seal 1520 beneath the upper outer flanged circular ring 1511 extends around a lower perimeter of the circular disc 1510 and is positioned between the circular disc 1510 and a top edge 1504 of the circular top mouth opening 1502 of the container 1501. The lower seal 1520 is beneath the upper outer flanged circular ring 1511 and extends around a lower perimeter of the circular disc 1510 and positioned between the circular disc 1510 and a top edge 1504 of the circular top mouth opening 1502 of the container 1501. The lower seal 1520 uses a sticky adhesive material. The lower seal 1520 can be a rubber or sticky food-grade material such as an FDA approved or food-grade adhesive. The lower seal 1520 can have an adhesive on both sides so as to create the seal. The lower seal 1520 material could be a PET, also known as polyethylene terephthalate, a type of thermoplastic polymer resin.

(69) The lower seal 1520 can have at least one grab tab 1522. The grab tab 1522 can have a fold to fit under a threaded screw on lid 1509 of the container 1501. The fold of the grab tab 1522 can extend beyond an outer perimeter of the circular disc no further than a thread depth of the threaded screw on lid 1509 and the container 1501 to avoid interference when screwing the lid onto the container.

(70) A flexible membrane 1530 can be fixed over the vent hole. The flexible membrane 1530 can be a material based on polypropylene and coated or multi-material which have the approval of FDA approved or food grade, and prevention of transmission of gases. The flexible membrane 1530 has a sticky lower part such as an FDA approved or food grade adhesive to stick to the top of the circular disc 1510. The flexible membrane 1530 can also have a grab tab for breaking the seal. The tabs such as tab 1522 can be pulled by an index finger and thumb of a user's hand.

(71) FIG. 16 illustrates a cutaway perspective view of the circular disc 1510 with integral knife 1515 according to the fourth embodiment of the present inventions. The open ring is a vent hole. A lower seal 1520 beneath the upper outer flanged circular ring 1511 extends around a lower perimeter of the circular disc 1510 and is positioned between the circular disc 1510. The lower seal 1520 is beneath the upper outer flanged circular ring 1511 and extends around a lower perimeter of the circular disc 1510.

(72) FIG. 17 illustrates a perspective view of the concentric handle formed by the circular disc with integral knife held between finger and thumb by a user according to the fourth embodiment of the present inventions. The open ring is a vent hole. The outer circumference of the circular disc 1510 forms a handle to be grasped by an index finger 1717 and thumb 1718 of a user's hand. FIG. 17 shows the circular disc 1510 has an integrally formed spreader 1515. The tabs such as tab 1522 of FIGS. 15 and 16 can also be pulled by an index finger 1717 and thumb 1718 of a user's hand.

(73) When a solid cover and some elastomeric material seals to the top of a jar, problems to be solved include distortion of jar, type of sealant, amount and thickness necessary, and set up time. Peanut butter is packaged in a PET type container that uses what some call a foil cover which is adhered to the top of the jar by some adhesive that joins the jar to the foil film. PET, also known as polyethylene terephthalate, is a type of thermoplastic polymer resin. The seal is present by the concave appearance of the top of the foil film to the jar, and by the fact that the cracking open or breaking of the foil film. It is thought that the material is packaged into the jar and the film/foil seal is applied, and that as the product cools the foil liner then gets sucked down into the jar to produce the concave appearance. It is not known what hold film/foil in place, and how quick the adhesive sets up. It appears good given jars inspected and the concave appearance of the film/foil on top of the jar. Basically shows that a seal is present to preserve contents.

(74) In testing a jar was used of the type the product was designed for and a flexible film was also used. Hot water, of approximately 190 F was poured into the jar and the film was stretch over the opening. The initial results were that the film expanded creating a dome over the opening of the jar and over time as the water temperature cooled the dome structure reversed itself and the film was sucked into the jar similar to what one see's when buying a new jar of peanut butter. A seal was formed, by use of this flexible film, and a vacuum was created by the cooling of temperature, and that the seal of film to jar remained.

(75) In another test a home canning lid was purchased and used with a larger plastic jar. It should be stated that the lid was rigid as it was from steel, and included a somewhat flexible gasket material on the perimeter of the lid. Again the initial test was to pour hot water into a jar, and place lid over it to see if by cooling the jar a seal would be formed. The initial test failed, as would be expected as no load was on lid, forming an initial seal. In the second test, a weight was added to the top of the lid to hold in place as to cause a seal initially from the gasketing material to jar rim. This in fact worked to a minor degree with the fluid and temperature used. But it was not enough to hold in place after a few hours of time has passed. In a third test with water in the range of 210 F and a heavier weight on the lid a great seal was achieved, but the down side was that the plastic jar material itself distorted. Distortion was possibly due to the weight and temperature used.

(76) The conclusion is that with a rigid product to form a seal, the gasketing/adhesive must be soft enough to allow it seal, or heat and seal. The possible issue is that if the product is too stiff to accept the vacuum to be created that the jar itself could distort. Not knowing the volumetric shrinkage of the product in the jar and or the air volume left in the jar and what fill temperature it is not known if distortion would occur. It is also thought that the screwing on of the lid may aid in the seal, though it would need to be tested, much like canning.

(77) The overall suggestion is to use an adhesive similar to what is on the foil liner today but to apply this to the outside ring of the product. This material shall need to be a bit thicker in application to compensate for the stiffness of the product. Meaning if any warpage occurs in product or that of the jar sealing surface the added adhesive can manage this mismatch. It may be necessary to use the jar lid to aid in compression initially of the product to the jar, much as in canning the ring holds the lid firmly to the glass jar to help provide the seal when all cools.
