3 TECHNICAL FIELD
4 [0001] The present invention relates to sealable containers such as MasonTM jars, and more particularly to a plug for use with a lid in a vacuum sealed container.
8 [0002] Home-made pickles, preserves, jams and the like, are typically stored in sealable 9 containers such as MasonTM jars. MasonTM jars are ideal for storing such home-made food because the food is placed in the pre-sterilized jars and then a lid with a rubber seal around the 11 circumference is located on the jar's rim. The level of oxygen is substantially reducing when 12 sterilizing so that the food inside the jar can be kept for a long period of time. As the interior of the 13 jar cools, the seal becomes stronger and remains so until the jar is opened. One of the more 14 favorable aspects of home-made jarred goods is that they typically lack chemical preservatives and therefore are considered to be healthier than store-bought jarred foods.
This is particularly 16 true for baby food when the contamination of baby food can cause gastrointestinal problems for 17 the baby. Once the jar is opened, however, the food inside is subject to contamination from 18 airborne pathogens such as bacteria, viruses and fungi. Storing the opened jar in a refrigerator is 19 often the mean used to store the opened jar, but the risk of food spoilage is still high. One drawback of sterilization is that the seal has to melt in the process to tightly secure the lid on the 21 jar. The lid, once the jar is opened after sterilization, has a damaged seal that is generally not 22 anymore in a condition to offer a good seal with the jar.
23 [0003] Thus, there is a need for an improved lid over the existing art.
It is desirable the improved 24 apparatus for sealing a container including a lid with a seal thereof that is re-usable, yet provides a quick and easy way to seal a container after it is opened or when closed for the first time during, 26 for example, making home-made food. It is desirable to have an improved lid over the existing art 27 that is capable of sealing jars of different opening sizes.

The thickness of the seal 50 can vary on the actual configuration of the lid 26 and seal 50 arrangement.
26 [0039] Referring now to Figure 5, there is illustrated generally a plug 100 for use with the lid 26 27 for sealing the lid opening 66. In one example, the container is a glass MasonTM jar, although one 28 skilled in the art will understand that the plug 100 will work with any container having a sealable 29 lid. The plug 100 is made from a resilient material, such as a silicon base, a rubber base or the like material, which is sufficiently flexible to allow the plug 100 to be inserted into the lid opening 31 66, but sufficiently strong to maintain a seal once the air is removed from the container and 32 pressure inside the container is lesser than the environment pressure.
Broadly speaking, the plug 33 100 includes a body 104 and a cap 108 that is dome-shaped in the illustrated embodiment. The 34 body 104 includes a proximal portion 112 and a distal portion 116. Both the proximal and distal 1 portions 112, 116 are respectively first and second solid cylindrical bodies 120, 124. The first 2 upper cylindrical body 120 is larger in diameter (volume) than the second cylindrical body 124.
3 This diameter difference is best seen in Figure 6. When viewed in cross section, the diameter of 4 the first cylindrical body 120 is larger than the diameter of the second cylindrical body 124. The second cylindrical body 124 is sufficiently small for a user to locate it through the lid opening 66.
6 A sealing portion 128 is located at the junction between the first and second cylindrical bodies 7 120, 124. When the second cylindrical body 124 is located in the lid opening 66 in an operable 8 configuration (as shown in Figure 6), the sealing portion 128 forms a secondary seal against the 9 inner sidewall of the lid opening 66. The lid opening 66 has a lid opening diameter and the diameter of the second cylindrical body 124 is smaller than the lid opening 66 diameter, to permit 11 insertion of the second cylindrical body 124 through the lid opening 66.
12 [0040] Referring now to Figure 1 throughout Figure 6, a longitudinal body axis 62 extends 13 through the first and second cylindrical bodies 120, 124, which when viewed in longitudinal cross 14 section, as seen in Figure 6 c), shows that the plug 100 is generally symmetrical about the axis 62. The sealing portion 128 is an annular sidewall 132, which tapers inwardly towards the body 16 axis 62 from a lower portion 136 of the first cylindrical body 120 to an upper portion 140 of the 17 second cylindrical body 124. At a lower portion 140 of the second cylindrical body 124 has an 18 increased diameter 144, that could also be embodied as flanges (not illustrated), which extends 19 radially outwardly from the second cylindrical body 124 and is generally orthogonal to the body axis 62. The increased diameter 144, as best seen in Figure 6 c), is wider than the lid opening 66 21 and prevents the second cylindrical body 124 from being inadvertently dislodged from the lid 22 opening 66 prior to and during evacuation by a vacuum pump 14, while at the same time providing 23 sufficient clearance (gap) between lid opening sidewall and the second cylindrical body 124 so 24 that air being drawn from the container can flow freely between the gap.
The increased diameter 144 is sufficiently flexible to allow the user to insert the second cylindrical body 124 through the 26 lid opening 66 and dislodge the plug 100 from the lid opening 66 whenever desired.
27 [0041] Still referring to Figure 1 throughout Figure 6, the illustrated dome-shaped cap 108 is 28 connected to a top portion 148 of the first cylindrical body 120. it should be noted that although 29 the examples illustrated show a dome-shaped cap 108, one skilled in the art will recognize that the shaped of the cap 108 can be changed depending on the ease of manufacture, the application 31 and the materials chosen for the manufacture of the plug 100. The shape of the cap 108 also 32 depends on the type of vacuum pump 14 being used to evacuate the container. The air from the 33 container could be more easily extracted via axial slots 152 depending on the selected 34 configuration. A vacuum-releasing member 154 can be appreciated from the Figures. The 1 vacuum-releasing member 154 can be pulled by a user to remove the vacuum in the container 2 and release the lid assembly 34 from the container's opening. Vacuum cancellation is done in two 3 steps given the two sealing stages provided by the plug 100. A first sealing stage is performed by 4 the sealing edge 156 of the plug 100 in contact with the lid 26, and the second sealing stage is achieved between the sealing portion 128 of the plug 100 body 104 in contact with the lid opening 6 66. Pulling on the vacuum-releasing member 154 is disconnecting the sealing edge 156 of the 7 plug in a first time and further pulling on the vacuum-releasing member 154 is going to disengage 8 the sealing portion 128 from the lid opening 66.
9 [0042] The cap 108 is sized and shaped to surround the lid opening 66 within the upper circular ridge 74 of the lid 42 to ensure optimal sealing of the plug 100 to the lid 42. The cap 108 has a 11 sealing edge 156 to sealingly engage the lid 42 around the lid opening 66, and therefore form a 12 primary seal between the plug 100 and the lid 42. Together, the body 104 and the cap 108 13 cooperate with the vacuum pump 14 so as to allow air removal from the container. The cap 108 14 is flexibly (hingedly) connected to the top portion 148 of the first cylindrical body 120 to permit movement of the cap 108 between an assembled configuration 160, as seen in Figure 6, and the 16 vacuumed configuration when the sealing portion 128 is moved lower in contact with the lid 17 opening 66 and the sealing edge 156 is in contact with the central surface 82 when the container 18 is vacuumed and the body 104 is pulled inside the lid opening 66. The cap 108 is hinged with 19 respect to the top portion 148 of the first cylindrical body 120 about an annular hinge 164. The cap 108 has an intermediate portion 168 located between the annular hinge 164 and the sealing 21 edge 156. The intermediate portion 168 is wider in cross section than the annular hinge 164 and 22 smaller than the peripheral sealing edge 156. The annular hinge 164 and the sealing edge 156 23 allow the intermediate portion 168 to move relative thereto, between the assembled configuration 24 160 configuration and the vacuumed configuration. The sealing edge 156 can include an optional annular wall 172 that is disposed downwardly towards the lid 42.
26 [0043] Moving now to Figure 7 illustrating a pump adaptor 18. The pump adaptor 18 is generally 27 hollowed and includes a lid-contacting side 176 and a pump-contacting side 180 preferably 28 molded in a material offering some flexibility that would ensure proper seal between the lid 26 and 29 the pump 14. The lid-contacting side 176 is embodied as a lid contacting portion 184 configured to fit inside the upward circular ridge 74 and contact the lid 26 to prevent air circulation 31 therebetween. The thickness and the shape of the contacting portion 184 can have different 32 configurations to work with lid assembly 34 using design variations. On the other axial side, the 33 pump-contacting side 180 includes a pump contacting portion 188 configured to cooperate with 34 the pump 14 with a junction thereof that prevents air circulation therebetween to create the desired 1 vacuum in the container. The thickness and the shape of the pump contacting portion 188 can 2 have different configurations to work with pumps 14 having design variations.
3 [0044] Another feature in embedded in the pump adaptor 18 to axially maintain the plug 100 in 4 its operating position in respect with the lid 26. In the embodiment illustrated in Figure 7, Figure 8 and Figure 9, one can appreciate the pump adaptor 18 includes a plug stopper 192 axially located 6 at a distance 196 to slightly contact, or having a slight play with the plug 100, to prevent the plug 7 to be aspired by the pump 14 when the pump is actuated and air is channeled from the container 8 to the environment through the pump 14 actuation. Openings 200 in the plug stopper 192, that is 9 embodied between semi-circular cross-like members 204 configured to stop the plug 100, allow air transmission through the plug stopper 192. The plug stopper 192 is housed in a cavity 208 11 sized and designed to encompass the plug 100 without interfering with its optimal operation. The 12 lid assembly 34 and the pump adaptor 18 are illustrated in Figure 9 in a possible operating 13 configuration.
14 [0045] In an exemplary typical use of the apparatus for sealing a container, a user would align the plug 100 along the axis 66 of the lid opening 66. Once the body 104 increased diameter 144 16 is manipulated to insert the second cylindrical body 124 through the lid opening 66, the vacuum 17 pump 14 with the pump adapter 18 is located over the plug 100 and pressed down onto the lid 26 18 of the container to ensure a good seal around the plug 100. As a vacuum pump piston 220 is 19 actuated along direction shown by arrow 224, a piston head 228 moves rearwardly by the user pulling on the piston 220 relative to the cylinder 232. This action draws the air out of the container 21 along the exemplary pathway 236 shown by the solid arrows. At the same time, the plug stopper 22 192 extending from the adapter 18 above the top portion 148 of the first cylindrical body 120 23 prevents the plug 100 from being displaced by the air suction. Once the optimal internal negative 24 pressure is achieved inside the container, the cap intermediate portion 168 moves outwardly about the hinge 164 so that the sealing portion 128 sealingly engages the lid opening 66 inner 26 sidewall and the sealing edge 156 sealingly contacts the lid 26. The vacuum pump 14 is then 27 removed from the plug 100. To release the plug 100, the user applies a force on the vacuum-28 releasing member 154 to locally lift the sealing edge 156 such that the seals are broken and the 29 air flows back into the container. The plug 100 is then removable from the lid 26 for cleaning.
Once the contents of the container are removed, the container can then be re-sealed by repeating 31 the steps described above.
32 [0046] While the invention has been described in connection with what is presently considered 33 to be the most practical and preferred embodiments, it is to be understood that the invention is 34 not to be limited to the disclosed embodiments and elements, but, to the contrary, is intended to 1 cover various modifications, combinations of features, equivalent arrangements, and equivalent 2 elements included within the spirit and scope of the appended claims.
Furthermore, the 3 dimensions of features of various components that may appear on the drawings are not meant 4 to be limiting, and the size of the components therein can vary from the size that may be portrayed in the figures herein. Thus, it is intended that the present invention covers the 6 modifications and variations of the invention, provided they come within the scope of the 7 appended claims and their equivalents.
The diameter of the upper 17 circular ridge 74 could vary depending on the plug diameter that could be adapted for a variety of 18 container's configurations.
19 [0038] The intervening seal 50 sized and designed to match the lower surface 46 of the lid 42 and the configuration of the downward circular ridge 58 is illustrated in Figure 4. The intervening 21 seal 50 is preferably of food-grade quality and resistant to dishwasher cleaning. The seal 50 is 22 preferably made of a material capable of sealing two surfaces together with some pressure 23 applied thereon. Silicon material could be an appropriate material given its flexibility, inert 24 composition and tolerance to chemical products and high heat. The thickness of the seal 50 can vary on the actual configuration of the lid 26 and seal 50 arrangement.
26 [0039] Referring now to Figure 5, there is illustrated generally a plug 100 for use with the lid 26 27 for sealing the lid opening 66. In one example, the container is a glass MasonTM jar, although one 28 skilled in the art will understand that the plug 100 will work with any container having a sealable 29 lid. The plug 100 is made from a resilient material, such as a silicon base, a rubber base or the like material, which is sufficiently flexible to allow the plug 100 to be inserted into the lid opening 31 66, but sufficiently strong to maintain a seal once the air is removed from the container and 32 pressure inside the container is lesser than the environment pressure.
Broadly speaking, the plug 33 100 includes a body 104 and a cap 108 that is dome-shaped in the illustrated embodiment. The 34 body 104 includes a proximal portion 112 and a distal portion 116. Both the proximal and distal 1 portions 112, 116 are respectively first and second solid cylindrical bodies 120, 124. The first 2 upper cylindrical body 120 is larger in diameter (volume) than the second cylindrical body 124.
3 This diameter difference is best seen in Figure 6. When viewed in cross section, the diameter of 4 the first cylindrical body 120 is larger than the diameter of the second cylindrical body 124. The second cylindrical body 124 is sufficiently small for a user to locate it through the lid opening 66.
6 A sealing portion 128 is located at the junction between the first and second cylindrical bodies 7 120, 124. When the second cylindrical body 124 is located in the lid opening 66 in an operable 8 configuration (as shown in Figure 6), the sealing portion 128 forms a secondary seal against the 9 inner sidewall of the lid opening 66. The lid opening 66 has a lid opening diameter and the diameter of the second cylindrical body 124 is smaller than the lid opening 66 diameter, to permit 11 insertion of the second cylindrical body 124 through the lid opening 66.
12 [0040] Referring now to Figure 1 throughout Figure 6, a longitudinal body axis 62 extends 13 through the first and second cylindrical bodies 120, 124, which when viewed in longitudinal cross 14 section, as seen in Figure 6 c), shows that the plug 100 is generally symmetrical about the axis 62. The sealing portion 128 is an annular sidewall 132, which tapers inwardly towards the body 16 axis 62 from a lower portion 136 of the first cylindrical body 120 to an upper portion 140 of the 17 second cylindrical body 124. At a lower portion 140 of the second cylindrical body 124 has an 18 increased diameter 144, that could also be embodied as flanges (not illustrated), which extends 19 radially outwardly from the second cylindrical body 124 and is generally orthogonal to the body axis 62. The increased diameter 144, as best seen in Figure 6 c), is wider than the lid opening 66 21 and prevents the second cylindrical body 124 from being inadvertently dislodged from the lid 22 opening 66 prior to and during evacuation by a vacuum pump 14, while at the same time providing 23 sufficient clearance (gap) between lid opening sidewall and the second cylindrical body 124 so 24 that air being drawn from the container can flow freely between the gap.
The increased diameter 144 is sufficiently flexible to allow the user to insert the second cylindrical body 124 through the 26 lid opening 66 and dislodge the plug 100 from the lid opening 66 whenever desired.
27 [0041] Still referring to Figure 1 throughout Figure 6, the illustrated dome-shaped cap 108 is 28 connected to a top portion 148 of the first cylindrical body 120. it should be noted that although 29 the examples illustrated show a dome-shaped cap 108, one skilled in the art will recognize that the shaped of the cap 108 can be changed depending on the ease of manufacture, the application 31 and the materials chosen for the manufacture of the plug 100. The shape of the cap 108 also 32 depends on the type of vacuum pump 14 being used to evacuate the container. The air from the 33 container could be more easily extracted via axial slots 152 depending on the selected 34 configuration. A vacuum-releasing member 154 can be appreciated from the Figures. The 1 vacuum-releasing member 154 can be pulled by a user to remove the vacuum in the container 2 and release the lid assembly 34 from the container's opening. Vacuum cancellation is done in two 3 steps given the two sealing stages provided by the plug 100. A first sealing stage is performed by 4 the sealing edge 156 of the plug 100 in contact with the lid 26, and the second sealing stage is achieved between the sealing portion 128 of the plug 100 body 104 in contact with the lid opening 6 66. Pulling on the vacuum-releasing member 154 is disconnecting the sealing edge 156 of the 7 plug in a first time and further pulling on the vacuum-releasing member 154 is going to disengage 8 the sealing portion 128 from the lid opening 66.
9 [0042] The cap 108 is sized and shaped to surround the lid opening 66 within the upper circular ridge 74 of the lid 42 to ensure optimal sealing of the plug 100 to the lid 42. The cap 108 has a 11 sealing edge 156 to sealingly engage the lid 42 around the lid opening 66, and therefore form a 12 primary seal between the plug 100 and the lid 42. Together, the body 104 and the cap 108 13 cooperate with the vacuum pump 14 so as to allow air removal from the container. The cap 108 14 is flexibly (hingedly) connected to the top portion 148 of the first cylindrical body 120 to permit movement of the cap 108 between an assembled configuration 160, as seen in Figure 6, and the 16 vacuumed configuration when the sealing portion 128 is moved lower in contact with the lid 17 opening 66 and the sealing edge 156 is in contact with the central surface 82 when the container 18 is vacuumed and the body 104 is pulled inside the lid opening 66. The cap 108 is hinged with 19 respect to the top portion 148 of the first cylindrical body 120 about an annular hinge 164. The cap 108 has an intermediate portion 168 located between the annular hinge 164 and the sealing 21 edge 156. The intermediate portion 168 is wider in cross section than the annular hinge 164 and 22 smaller than the peripheral sealing edge 156. The annular hinge 164 and the sealing edge 156 23 allow the intermediate portion 168 to move relative thereto, between the assembled configuration 24 160 configuration and the vacuumed configuration. The sealing edge 156 can include an optional annular wall 172 that is disposed downwardly towards the lid 42.
26 [0043] Moving now to Figure 7 illustrating a pump adaptor 18. The pump adaptor 18 is generally 27 hollowed and includes a lid-contacting side 176 and a pump-contacting side 180 preferably 28 molded in a material offering some flexibility that would ensure proper seal between the lid 26 and 29 the pump 14. The lid-contacting side 176 is embodied as a lid contacting portion 184 configured to fit inside the upward circular ridge 74 and contact the lid 26 to prevent air circulation 31 therebetween. The thickness and the shape of the contacting portion 184 can have different 32 configurations to work with lid assembly 34 using design variations. On the other axial side, the 33 pump-contacting side 180 includes a pump contacting portion 188 configured to cooperate with 34 the pump 14 with a junction thereof that prevents air circulation therebetween to create the desired 1 vacuum in the container. The thickness and the shape of the pump contacting portion 188 can 2 have different configurations to work with pumps 14 having design variations.
3 [0044] Another feature in embedded in the pump adaptor 18 to axially maintain the plug 100 in 4 its operating position in respect with the lid 26. In the embodiment illustrated in Figure 7, Figure 8 and Figure 9, one can appreciate the pump adaptor 18 includes a plug stopper 192 axially located 6 at a distance 196 to slightly contact, or having a slight play with the plug 100, to prevent the plug 7 to be aspired by the pump 14 when the pump is actuated and air is channeled from the container 8 to the environment through the pump 14 actuation. Openings 200 in the plug stopper 192, that is 9 embodied between semi-circular cross-like members 204 configured to stop the plug 100, allow air transmission through the plug stopper 192. The plug stopper 192 is housed in a cavity 208 11 sized and designed to encompass the plug 100 without interfering with its optimal operation. The 12 lid assembly 34 and the pump adaptor 18 are illustrated in Figure 9 in a possible operating 13 configuration.
14 [0045] In an exemplary typical use of the apparatus for sealing a container, a user would align the plug 100 along the axis 66 of the lid opening 66. Once the body 104 increased diameter 144 16 is manipulated to insert the second cylindrical body 124 through the lid opening 66, the vacuum 17 pump 14 with the pump adapter 18 is located over the plug 100 and pressed down onto the lid 26 18 of the container to ensure a good seal around the plug 100. As a vacuum pump piston 220 is 19 actuated along direction shown by arrow 224, a piston head 228 moves rearwardly by the user pulling on the piston 220 relative to the cylinder 232. This action draws the air out of the container 21 along the exemplary pathway 236 shown by the solid arrows. At the same time, the plug stopper 22 192 extending from the adapter 18 above the top portion 148 of the first cylindrical body 120 23 prevents the plug 100 from being displaced by the air suction. Once the optimal internal negative 24 pressure is achieved inside the container, the cap intermediate portion 168 moves outwardly about the hinge 164 so that the sealing portion 128 sealingly engages the lid opening 66 inner 26 sidewall and the sealing edge 156 sealingly contacts the lid 26. The vacuum pump 14 is then 27 removed from the plug 100. To release the plug 100, the user applies a force on the vacuum-28 releasing member 154 to locally lift the sealing edge 156 such that the seals are broken and the 29 air flows back into the container. The plug 100 is then removable from the lid 26 for cleaning.
Once the contents of the container are removed, the container can then be re-sealed by repeating 31 the steps described above.
32 [0046] While the invention has been described in connection with what is presently considered 33 to be the most practical and preferred embodiments, it is to be understood that the invention is 34 not to be limited to the disclosed embodiments and elements, but, to the contrary, is intended to 1 cover various modifications, combinations of features, equivalent arrangements, and equivalent 2 elements included within the spirit and scope of the appended claims.
Furthermore, the 3 dimensions of features of various components that may appear on the drawings are not meant 4 to be limiting, and the size of the components therein can vary from the size that may be portrayed in the figures herein. Thus, it is intended that the present invention covers the 6 modifications and variations of the invention, provided they come within the scope of the 7 appended claims and their equivalents.
