- a solid vessel or a canning container generally indicated at 20 in FIG. 2 , such as a jar or can and then allowing the contents to cool, thus creating a vacuum seal.
- typical canning containers 20 are made of glass, but other materials such as metal or plastic could be employed.
- the reusable canning lid system 10 includes a sealing device such as a seal 25 , a reusable canning lid device such as a lid 30 , and a fastening device such as a band 40 , all according to one embodiment of the present invention.
- the seal 25 is adapted to seal the opening of the canning container 20 .
- the seal 25 is a ring or has a ring shape.
- the seal 25 is made from an elastomeric material.
- the elastomeric material is a food grade Nitrile rubber that has a durometer reading of 70 on the Shore A scale.
- the elastomeric material contains no latex. It should be appreciated that the seal 25 may be of different material types, grades, and hardness based on the requirements of the particular application.
- the lid 30 is adapted to close an opening of the canning container 20 .
- the lid 30 is generally circular in shape, but may have any suitable shape to close the opening of the container 20 .
- the lid 30 is made from a plastic material.
- the plastic material is of a food grade type.
- the plastic material is bisphenol-a (BPA) free.
- BPA bisphenol-a
- the plastic material may be an acetal copolymer plastic, a typical type being under the trade name Celcon M90 manufactured by Celanese. It should be appreciated that the lid 30 may be made of a metal or a combination of metal and plastic.
- the fastening device is called the band 40 in the food canning industry and is adapted to affix the lid 30 to the canning container 20 .
- the band 40 has an annular or ring shape.
- the band 40 has one or more threads for threadably engaging or mating with threads of the container 20 .
- the band 40 is typically made of metal.
- the band 40 may be made of a plastic material.
- the lid 30 , seal 25 , and container 20 can be made of different materials. It should be appreciated that, in another embodiment, the band 40 may include at least one snap configured to snap-on the container 20 .
- the canning process involves heating the components of the system 10 to a temperature to ensure that they are as bacteria free as possible in an approximate range of 170-250 degrees Fahrenheit.
- the container 20 is then filled with a desired content and the seal 25 , lid 30 , and band 40 then attached.
- the band 40 is tightened to finger tight and then loosened by one quarter inch as shown in FIGS. 1 and 2 .
- the loosening of the band 40 will allow the remaining air in the container 20 to vent as pressure builds during subsequent heating cycles.
- the system 10 is removed from any heat source and allowed to cool.
- the present invention provides a lid 30 , according to one embodiment of the present invention, that allows for the lid 30 to be tightened without necessitating the subsequent loosening by a predetermined amount and eliminates the previous learning technique.
- the lid 30 of the present invention therefore provides foolproof sealing of canned contents.
- the lid 30 includes one or more, preferably three, raised portions 50 a, 50 b, and 50 c equidistant from each other around an outer perimeter of the lid 30 .
- the raised portions 50 a, 50 b, and 50 c provide a non-equal sealing force on the seal 25 when affixed by the band 40 to the container 20 .
- the band 40 includes a rolled edge 60 that makes contact with the raised portions 50 a, 50 b, and 50 c. As the band 40 is tightened, force is applied and concentrated on the raised portions 50 a, 50 b, and 50 c.
- One skilled in the art would be able to arrange the raised portions 50 a, 50 b, and 50 c on the lid 30 to contact the band 40 in areas other than the rolled edge 60 .
- the lid 30 has one or more circumferential portions or lip 70 that are between the raised portions 50 a, 50 b, and 50 c and do not receive direct force from the band 40 , but have force applied indirectly through the rigidity of the material for the lid 30 .
- the raised portion of the lid 30 is a continuous raised portion of a predetermined length. As illustrated in FIG. 5 , the lid 30 has a raised portion 55 with at least one sloping edge or tapered end or ends 57 a and 57 b that conjoin with an upper surface or non-raised portion 80 of the lid 30 .
- the length of the raised portion 55 is defined by a central angle cc of about 250°-300° as illustrated in FIG. 5 a that allows the venting process to occur.
- the raised portion 55 and non-raised portion 80 are reversed so that raised portion 55 is an acute angle and the non-raised portion 80 is approximately 250°-300° as illustrated in FIG. 5 b .
- the venting function becomes more independent of how tight the band 40 is on the container 20 because the force is applied to a small area and the surface area of the non-raised portion 80 is allowed to move up freely eliminating the prior problems with over-tightening the bands 40 .
- the ratios of thickness between the portions 55 and 80 are adjusted based on the thickness and diameter of the lid 30 .
- the feature as illustrated in FIG. 5 b eliminates unsafe pressure build up when the canner or operator over-tightens the band 40 , thereby providing a significant safety improvement over prior canning processes.
- the overall thickness of the lip 70 on the lid 30 in FIG. 4 is critical.
- the thickness of the lip 70 increases, the thread engagement between the band 40 and container 20 is reduced, potentially allowing stripping of the band 40 from the container 20 . If the contents are under pressure at the time because the container 20 is relatively hot, the contents could be released from the container 20 , creating a potentially hazardous condition. Once the band 40 has been stripped from the container 40 , the band is unsafe because it will not tighten onto the container 20 appropriately.
- the overall thickness of the lid 30 does not need to be increased. It should be appreciated that this allows the molding of lids 30 to improve the canning process without the increase in band stripping that would occur if the raised portion 55 increased the overall thickness of the lip 70 . It should also be appreciated that, if it is desired to back off the tightness of the lid 30 to avoid the risk of having the band 40 strip off the threads of the container 20 , the band 40 can be loosened as previously described.
- indicators 120 may be used in connection with the lid 30 to indicate or gauge the amount or degree of loosening.
- a previously described technique is to loosen the band 40 by a predetermined amount, for example, such as a quarter inch (1 ⁇ 4′′). This can visually be hard to achieve with no reference indicators such as marks while holding hot contents within the container 20 .
- the indicators 120 are molded into the lids 30 circumferentially a predetermined amount, for example, every quarter inch (1 ⁇ 4′′) (or other desired index amount) to aid in loosening the band 40 by a fixed amount. It should be appreciated that the indicators 120 may be straight lines or have any suitable configuration.
- the tapered ends 57 a and 57 b of the raised portion 55 are of such an angle that the sudden change in surface height from the surface of the non-raised portion 80 to the top of raised portion 55 is minimized. This gradual increasing of height from the surface of the non-raised portion 80 to the top of the raised portion 55 helps maintain the surface planarity (reduce sink) of the lid 30 .
- FIGS. 5 c through 5 f Other embodiments of the lid 30 are shown in FIGS. 5 c through 5 f .
- FIGS. 5 c and 5 d illustrate the configurations of FIGS. 5 a and 5 b but with the surface of the portion 80 remaining at a nominal thickness and the surface 56 of the lip 70 being thinned. It should be appreciated that this configuration provides the desired functional behavior of the lid 30 .
- the system 10 is shown with the lid 30 having the raised portion 55 , the nominal upper surface of the portion 80 , and the lip 70 , the seal 25 , the container 20 , and the band 40 with the rolled edge 60 .
- the raised portion 55 on the lip 70 will receive force directly from the rolled edge 60 of the band 40 when the band 40 is screwed on and tightened down.
- the area of the lip 70 that is at the nominal surface of the portion 80 will not receive downward force directly from the band 40 , but will receive force indirectly through the rigidity of the material of the lid 30 . This lack of direct applied force allows for slight but adequate deflection of the lip 70 of the lid 30 to allow for venting of internal pressure built up during the normal canning process.
- the width of the raised portion 55 is such that it will accommodate a variation in location of the rolled edge 60 of the band 40 . Therefore, bands of different manufacturers with slight variations in dimension will all perform similarly with the lids 30 of the system 10 .
- the lid 30 of FIGS. 5 and 6 includes an outer edge that has a predetermined radius 90 .
- Some fastening devices or bands such as those used commonly in the canning industry have a radius or rounded inside portion such that an interference would occur if it were not for the radius 90 of the lid 30 .
- the rolled edge 60 is the desired portion of the band 40 that is to come into contact with the lid 30 , portion 80 , or raised portions 50 a, 50 b, 50 c, or 55 of the lid 30 . It is not desirable for the engagement force to be applied at the outside upper edge of the lid 30 .
- the exemplary design therefore has the outside upper edge of the lid 30 rounded with a predetermined radius 90 to ensure a force is applied to the lid 30 other than to aforementioned portions 80 , 50 a, 50 b, 50 c, or 55 .
- the lid 30 includes projections or details 100 that engage and hold the seal 25 so that lateral movement during pressurization is minimized. It should be appreciated that FIG. 6 shows the details 100 embedded into the seal 25 .
- the lid 30 includes a lower portion 102 having a ridge 75 and ledge 76 such that it aligns with an inside radius 77 of the raised portion 55 of similar lids 30 so that the lids 30 become stackable.
- the lid 30 includes one or more posts 101 that can be used to engage the lower portion 102 to allow stacking of the lids 30 .
- one or more features that accomplish controlled location of applied force may be placed into the metal or plastic band 40 as one or more raised portions such as depressions 110 illustrated in FIGS. 9 and 9 a which form recessed or non-raised portions therebetween. It is understood that there does not have to be three depressions 110 as illustrated in FIGS. 9 and 9 a . There can be any number of depressions 110 , with a minimum of one depression 110 , which accomplishes the desired function of controlling the location of applied force to provide a non-equal sealing force when affixed to the container 20 . It should be appreciated that these one or more features such as depressions 110 may be on the lid 30 described previously.
- the seal 25 is integral with the lid 30 and could be formed by a two-step injection molding process. It should be appreciated that the injection molding process is known.

Abstract
A reusable canning lid device and system for a canning container includes a plastic lid, a seal, and a band. The lid or band includes a raised portion such that the seal is not circumferentially equal in compressed communication which allows relief of pressure built up in a typical pressure canning, water bath, or vacuum sealing application. This makes it safe to the risk of overpressure and scalding. It is an important advance in the technology of canning and other applications of pressure control in thermal situations. Safety is very important to a typical canner who has limited capability to prevent explosive pressures from building up due to steam pressure expansion and high forces causing container bursts.
Description
- The present application claims priority to and all the benefits of U.S. Provisional Patent Application No. 62/005,301, filed on May 30, 2014, which is hereby expressly incorporated herein by reference in its entirety.
- 1. Field of the Invention
- The present invention relates generally to canning lids for canning containers and, more particularly, to a resuseable canning lid device and system for a canning container.
- 2. Description of the Related Art
- It is known to provide a process for preserving food through canning. The process for canning to preserve food was first proven in the early 1800's and used a container such as a glass jar, a flat lid made of metal such as tin, and a seal such as wax. Later improvements to the early canning process came with the advent of the Mason jar and its reusable screw-on threaded band for providing a sealing mechanism between a metal lid of zinc with a rubber ring and a glass container with a mating thread molded at the opening. The rubber ring created a seal maintained by the threaded band screwed in place. Throughout its history, the metal lid and wax seal have not been reusable.
- The advent and development of these components provided an affordable and easy to use method for home canning and became popular for preserving consumable foodstuff such as sauces, pickles, relishes, fruit and tomatoes. This was an important development in the era pre-dating the common use of refrigeration and convenience stores for obtaining and keeping food from spoilage.
- Other developments have followed to accomplish the same results, for example, jar variations allowing the use of glass lids held in place with a metal clamp for eliminating corrosion concerns and subsequent loss of seal leading to food contamination. Further improvements to this style of jar and seal included a raised lip to help keep the jar from cracking.
- Mass production and distribution of glass canning jars began in the early 1900's, led by the Ball Corporation. Easier to fill wide-mouth jars were introduced around this time, as well as the innovation of permanently attaching the gasket seal to the metal lid. By 1915, a smaller, flat metal lid with the same permanent composition gasket seal had been developed using the same practice of screwing a metal band onto a glass jar to seal and hold the lid in place during hot water processing. This improved the two-part lid system, thereby allowing canning jars to be used over and over with low cost and easy to use disposable metal lids that are presently still commonly in use.
- The development of engineering plastics in recent decades has allowed further advancements for canning practices. Plastic materials offer many advantages when compared to metals, ranging from better versatility of part geometry to chemical and corrosion resistance. Many plastics can be recycled to satisfy the growing demand to eliminate waste and support environmental and sustainability initiatives.
- In the 1970's, TATTLER Reusable Plastic Canning Lids began being manufactured using a plastic compound that is safe for direct contact with food products. The food grade plastic used is known as Polyoxymethylene Copolymer (POM) or Acetal Copolymer. It is bisphenol-a (BPA) free, and FDA and USDA approved. The rubber rings (gaskets) are made from a food grade nitrile rubber and contain no latex.
- It is, therefore, desirable to provide a canning lid device for a canning container that is reusable. It is also desirable to provide a canning lid device for a canning container that has a plastic lid. It is further desirable to provide a canning lid device for a canning container that relieves pressure built up during a canning process. As such, there is a need in the art to provide a reuseable canning lid and system that meets at least one of these desires.
- Accordingly, the present invention provides a reuseable canning lid device including a lid made of a plastic material and at least one raised portion on the lid adapted to provide a non-equal sealing force when affixed by a fastening device to a canning container.
- Also, the present invention provides a reusable canning lid system including a lid made of a plastic material and a band adapted to mate with a canning container and at least one raised portion on the band adapted to provide non-equal sealing force on a lid when affixed to a canning container.
- Further, the present invention provides a reusable canning lid device including a plastic lid and at least one thinned portion on the lid with a first portion of nominal thickness and a second portion thinner than the first portion and adapted to allow flexure when under pressure when affixed by a fastening device to a canning container.
- Yet, the present invention provides a reuseable canning lid system for a canning container including a plastic lid adapted to close an opening of the canning container and a seal adapted for forming a vacuum seal between the lid and the canning container. The reusable canning lid system also includes a band adapted to be affixed to the canning container. The lid includes a non-thinned portion adapted to receive pressure from the band and a thinned portion adapted to provide access for the seal, whereby the seal is compressed between the lid and an edge of the opening of the canning container from pressure applied by the band. The seal is not circumferentially equal in compressed communication with the raised portion to allow a relief of pressure built up in a typical pressure canning, water bath, or vacuum sealing application.

FIG. 10 a is a top view of another embodiment, according to the present invention, of the reusable canning lid device. -
FIG. 10 b is a perspective view of the reusable canning lid device ofFIG. 10 a. - Referring to the figures, wherein like numerals indicate like parts throughout the several views, one embodiment of a reusable canning lid system, according to the present invention, is shown generally at 10 in
FIG. 1 . A typical application for the reusablecanning lid system 10 is canning contents such as food through the well-known process of heating the contents inside a solid vessel or a canning container, generally indicated at 20 inFIG. 2 , such as a jar or can and then allowing the contents to cool, thus creating a vacuum seal. It should be appreciated thattypical canning containers 20 are made of glass, but other materials such as metal or plastic could be employed. - Referring to
FIGS. 1 and 2 , the reusablecanning lid system 10 includes a sealing device such as aseal 25, a reusable canning lid device such as alid 30, and a fastening device such as aband 40, all according to one embodiment of the present invention. Theseal 25 is adapted to seal the opening of thecanning container 20. Theseal 25 is a ring or has a ring shape. Theseal 25 is made from an elastomeric material. The elastomeric material is a food grade Nitrile rubber that has a durometer reading of 70 on the Shore A scale. The elastomeric material contains no latex. It should be appreciated that theseal 25 may be of different material types, grades, and hardness based on the requirements of the particular application. - The
lid 30 is adapted to close an opening of thecanning container 20. Thelid 30 is generally circular in shape, but may have any suitable shape to close the opening of thecontainer 20. Thelid 30 is made from a plastic material. The plastic material is of a food grade type. The plastic material is bisphenol-a (BPA) free. The plastic material may be an acetal copolymer plastic, a typical type being under the trade name Celcon M90 manufactured by Celanese. It should be appreciated that thelid 30 may be made of a metal or a combination of metal and plastic. - The fastening device is called the
band 40 in the food canning industry and is adapted to affix thelid 30 to thecanning container 20. Theband 40 has an annular or ring shape. Theband 40 has one or more threads for threadably engaging or mating with threads of thecontainer 20. Theband 40 is typically made of metal. Theband 40 may be made of a plastic material. For processing other contents that are not perishable such as paints, gels, adhesives and the like, thelid 30,seal 25, andcontainer 20 can be made of different materials. It should be appreciated that, in another embodiment, theband 40 may include at least one snap configured to snap-on thecontainer 20. - The canning process involves heating the components of the
system 10 to a temperature to ensure that they are as bacteria free as possible in an approximate range of 170-250 degrees Fahrenheit. Thecontainer 20 is then filled with a desired content and theseal 25,lid 30, andband 40 then attached. Theband 40 is tightened to finger tight and then loosened by one quarter inch as shown inFIGS. 1 and 2 . This is atypical of the canning process that uses a standard metal lid which allows for the tightening of theband 40 with no metered loosening required. The loosening of theband 40 will allow the remaining air in thecontainer 20 to vent as pressure builds during subsequent heating cycles. After the last heating cycle, thesystem 10 is removed from any heat source and allowed to cool. Since air in thecontainer 20 has vented between theseal 25 andcontainer 20 when at an elevated temperature, the air in thecontainer 20 will start to draw a vacuum as it cools. When thecontainer 20 is completely cooled, an adequate vacuum is present to ensure the food contents are preserved for long term storage. - An issue that has occurred in the aforementioned process is that if the
band 40 is tightened too tightly to allow for air to be vented during the heating process, no vacuum seal is created and hence the food contents are not preserved. Therefore, tightening of theband 40 becomes a critical component to the canning sealing process and, as a result, a person unfamiliar with the learned technique may become discouraged. - To overcome this issue, the present invention provides a
lid 30, according to one embodiment of the present invention, that allows for thelid 30 to be tightened without necessitating the subsequent loosening by a predetermined amount and eliminates the previous learning technique. Thelid 30 of the present invention therefore provides foolproof sealing of canned contents. Referring toFIG. 3 , in one embodiment, thelid 30 includes one or more, preferably three, raisedportions lid 30. The raisedportions seal 25 when affixed by theband 40 to thecontainer 20. InFIG. 4 , thesystem 10 that employs thelid 30 is illustrated. Theband 40 includes a rollededge 60 that makes contact with the raisedportions band 40 is tightened, force is applied and concentrated on the raisedportions portions lid 30 to contact theband 40 in areas other than the rollededge 60. Thelid 30 has one or more circumferential portions orlip 70 that are between the raisedportions band 40, but have force applied indirectly through the rigidity of the material for thelid 30. This lack of direct applied force allows for slight but adequate deflection of thelip 70 to allow for venting of internal pressure built up during the normal canning process. It should be appreciated that the raisedportions FIG. 3 can be applied to all types oflids 30 including metal, plastic, and glass. - In another embodiment, the raised portion of the
lid 30 is a continuous raised portion of a predetermined length. As illustrated inFIG. 5 , thelid 30 has a raisedportion 55 with at least one sloping edge or tapered end or ends 57 a and 57 b that conjoin with an upper surface ornon-raised portion 80 of thelid 30. The length of the raisedportion 55 is defined by a central angle cc of about 250°-300° as illustrated inFIG. 5 a that allows the venting process to occur. In another embodiment, the raisedportion 55 andnon-raised portion 80 are reversed so that raisedportion 55 is an acute angle and thenon-raised portion 80 is approximately 250°-300° as illustrated inFIG. 5 b. With less contact by theband 40, the venting function becomes more independent of how tight theband 40 is on thecontainer 20 because the force is applied to a small area and the surface area of thenon-raised portion 80 is allowed to move up freely eliminating the prior problems with over-tightening thebands 40. The ratios of thickness between theportions lid 30. The feature as illustrated inFIG. 5 b eliminates unsafe pressure build up when the canner or operator over-tightens theband 40, thereby providing a significant safety improvement over prior canning processes. Likewise, the overall thickness of thelip 70 on thelid 30 inFIG. 4 is critical. As the thickness of thelip 70 increases, the thread engagement between theband 40 andcontainer 20 is reduced, potentially allowing stripping of theband 40 from thecontainer 20. If the contents are under pressure at the time because thecontainer 20 is relatively hot, the contents could be released from thecontainer 20, creating a potentially hazardous condition. Once theband 40 has been stripped from thecontainer 40, the band is unsafe because it will not tighten onto thecontainer 20 appropriately. By changing the thickness of thelip 70 from a nominal dimension, the overall thickness of thelid 30, for example, does not need to be increased. It should be appreciated that this allows the molding oflids 30 to improve the canning process without the increase in band stripping that would occur if the raisedportion 55 increased the overall thickness of thelip 70. It should also be appreciated that, if it is desired to back off the tightness of thelid 30 to avoid the risk of having theband 40 strip off the threads of thecontainer 20, theband 40 can be loosened as previously described. - Referring to
FIGS. 10 a and 10 b, another embodiment, according to the present invention, of thelid 30 is shown. As illustrated,indicators 120 may be used in connection with thelid 30 to indicate or gauge the amount or degree of loosening. A previously described technique is to loosen theband 40 by a predetermined amount, for example, such as a quarter inch (¼″). This can visually be hard to achieve with no reference indicators such as marks while holding hot contents within thecontainer 20. In one embodiment, theindicators 120 are molded into thelids 30 circumferentially a predetermined amount, for example, every quarter inch (¼″) (or other desired index amount) to aid in loosening theband 40 by a fixed amount. It should be appreciated that theindicators 120 may be straight lines or have any suitable configuration. - Referring to
FIG. 5 , the tapered ends 57 a and 57 b of the raisedportion 55 are of such an angle that the sudden change in surface height from the surface of thenon-raised portion 80 to the top of raisedportion 55 is minimized. This gradual increasing of height from the surface of thenon-raised portion 80 to the top of the raisedportion 55 helps maintain the surface planarity (reduce sink) of thelid 30. - Other embodiments of the
lid 30 are shown inFIGS. 5 c through 5 f.FIGS. 5 c and 5 d illustrate the configurations ofFIGS. 5 a and 5 b but with the surface of theportion 80 remaining at a nominal thickness and thesurface 56 of thelip 70 being thinned. It should be appreciated that this configuration provides the desired functional behavior of thelid 30. - Referring to
FIG. 6 , thesystem 10 is shown with thelid 30 having the raisedportion 55, the nominal upper surface of theportion 80, and thelip 70, theseal 25, thecontainer 20, and theband 40 with the rollededge 60. As with thesystem 10 illustrated inFIGS. 3 and 4 , the raisedportion 55 on thelip 70 will receive force directly from the rollededge 60 of theband 40 when theband 40 is screwed on and tightened down. The area of thelip 70 that is at the nominal surface of theportion 80 will not receive downward force directly from theband 40, but will receive force indirectly through the rigidity of the material of thelid 30. This lack of direct applied force allows for slight but adequate deflection of thelip 70 of thelid 30 to allow for venting of internal pressure built up during the normal canning process. - The width of the raised
portion 55 is such that it will accommodate a variation in location of the rollededge 60 of theband 40. Therefore, bands of different manufacturers with slight variations in dimension will all perform similarly with thelids 30 of thesystem 10. - Referring to
FIG. 7 , thelid 30 ofFIGS. 5 and 6 includes an outer edge that has a predeterminedradius 90. Some fastening devices or bands such as those used commonly in the canning industry have a radius or rounded inside portion such that an interference would occur if it were not for theradius 90 of thelid 30. The rollededge 60 is the desired portion of theband 40 that is to come into contact with thelid 30,portion 80, or raisedportions lid 30. It is not desirable for the engagement force to be applied at the outside upper edge of thelid 30. The exemplary design therefore has the outside upper edge of thelid 30 rounded with apredetermined radius 90 to ensure a force is applied to thelid 30 other than toaforementioned portions - It is a further object of the present invention to have a feature integrated into the
lids 30 such that theseal 25 can be held in place while pressure is built-up inside thecontainer 20 during a heating cycle. InFIG. 7 , thelid 30 includes projections ordetails 100 that engage and hold theseal 25 so that lateral movement during pressurization is minimized. It should be appreciated thatFIG. 6 shows thedetails 100 embedded into theseal 25. - In another embodiment of the present invention illustrated in
FIG. 8 , thelid 30 includes alower portion 102 having aridge 75 andledge 76 such that it aligns with aninside radius 77 of the raisedportion 55 ofsimilar lids 30 so that thelids 30 become stackable. In other embodiments illustrated inFIGS. 8 and 8 a, thelid 30 includes one ormore posts 101 that can be used to engage thelower portion 102 to allow stacking of thelids 30. - In a further embodiment of the present invention, one or more features that accomplish controlled location of applied force may be placed into the metal or
plastic band 40 as one or more raised portions such asdepressions 110 illustrated inFIGS. 9 and 9 a which form recessed or non-raised portions therebetween. It is understood that there does not have to be threedepressions 110 as illustrated inFIGS. 9 and 9 a. There can be any number ofdepressions 110, with a minimum of onedepression 110, which accomplishes the desired function of controlling the location of applied force to provide a non-equal sealing force when affixed to thecontainer 20. It should be appreciated that these one or more features such asdepressions 110 may be on thelid 30 described previously. - In another embodiment of the present invention, the
seal 25 is integral with thelid 30 and could be formed by a two-step injection molding process. It should be appreciated that the injection molding process is known. - The present invention provides a method of venting internal pressure when an outside of the solid vessel or
canning container 20 is heated. The method includes the steps of providing thelid 30, theseal 25, and theband 40. Thelid 30 has at least one raisedportion band 40 and at least one lower surface orportion 80 not in contact with theband 40. The method also includes the step of contacting the solid vessel orcanning container 20 with theseal 25 and contacting thelid 30 with theband 40 and the solid vessel orcanning container 20 to hold thelid 30 in place to the solid vessel orcanning container 20. - In another embodiment, the method includes the steps of providing the
band 40 having at least raisedportion 110 which contacts thelid 30 and at least one recessed portion not in contact with thelid 30. The method also includes contacting the solid vessel orcanning container 20 with theseal 25 and contacting thelid 30 with theband 40 and the solid vessel orcanning container 20 to hold thelid 30 in place to the solid vessel orcanning container 20. - The present invention further provides a canning lid kit that includes the
lid 30, theseal 25, and theband 40. In one embodiment, thelid 30 has at least one raisedportion band 40 and at least onelower portion 80 not in contact with theband 40. In another embodiment, theband 40 having at least one raisedportion 110 which contacts thelid 30 and at least one recessed portion not in contact with thelid 30. - The present invention has been described in an illustrative manner. It is to be understood that the terminology, which has been used, is intended to be in the nature of words of description rather than of limitation.
- Many modifications and variations of the present invention are possible in light of the above teachings. Therefore, within the scope of the appended claims, the present invention may be practiced other than as specifically described.
