Definitions

  • This invention relates to vacuum sealers. More particularly, the invention relates to vacuum sealers with an adjustable head configured to engage and seal containers and bags.
  • This procedure is initiated by pressing a start button once the lid is closed and the procedure which follows is fully automatic.
  • a disadvantage of this type of vacuum sealer is that the entire volume of the chamber must be evacuated regardless of the volume of the bag.
  • the second common method employs a vacuum sealer which has an anvil of resilient material and a sealer bar which can be lowered to grip the mouth region of the bag between itself and the anvil.
  • a vacuum pipe passes between the anvil and sealer bar and enters the bag.
  • Pneumatic cylinders press the sealer bar against the anvil and the sealer bar itself presses the part of the pipe which is between the anvil and sealer bar into the resilient material of the anvil.
  • the air in the bag is sucked out through the pipe. Thereafter the pipe is withdrawn from the bag and from between the anvil and the sealer bar.
  • the space left by the pipe as it withdraws is immediately closed-up by the material of the anvil which expands resiliently to fill the space and maintain the mouth of the bag sealed.
  • the bag can be sucked onto the pipe inlet end. Once the pipe inlet end is obstructed the time taken to evacuate the bag increases and a poor vacuum is obtained, there usually being residual air left in the bag.
  • the present invention provides a vacuum sealer including a base defining a support surface and a body extending from the base.
  • a suction head is supported by the body and is moveable along the body toward and away from the support surface.
  • the suction head supports a suction assembly including a suction inlet with a sealing member thereabout.
  • a suction pump is configured to selectively provide a suction force to the suction inlet.
  • the vacuum sealer base defines a reference platform aligned with the suction assembly such that a valve assembly of a container or bag is easily alignable with the suction assembly.
  • the vacuum sealer includes a microcontroller and a motor configured to actuate the suction pump and the microcontroller is associated with one or both of a manual switch or an automatic switch configured to signal the micorcontroller to activate the motor.
  • the automatic switch is configured to signal the microcontroller when the suction assembly is forced into the suction head by a given distance.
  • the vacuum sealer includes a sensor configured to sense the vacuum pressure of a container or bag engaged by the suction assembly and the microcontroller is configured to deactivate the motor when a given vacuum pressure is reached.
  • the suction assembly is moveable relative to the suction head and the suction assembly is biased to a position wherein the sealing member is furthest from the suction head.
  • a guide extends within the body to define a linear track for the suction head and the suction head includes a guide arm extending from a support platform of the suction head to a guide block positioned within the body and configured for movement along the linear track.
  • the support platform supports at least one brake member which is biased such that a brake pad thereof engages a face of a body housing and locks the position of the suction head relative to the support surface.
  • a release button may be associated with each brake member.
  • the release button includes a sloped surface which engages a sloped surface of the brake member such that depression of the release button causes the brake member to move away from the face thereby disengaging the brake pad and allowing movement of the suction head relative to the body.
  • the suction assembly includes a vacuum chamber into which the suction inlet opens and a suction outlet which is in fluid communication with the suction pump.
  • a water flow mechanism may be positioned in the suction outlet and configured to signal a microcontroller to deactivate the suction pump upon detection of liquid in the vacuum chamber.
  • the suction assembly may also include a liquid receiving chamber about the vacuum chamber which is configured to receive any liquid extracted via the suction inlet.
  • the vacuum sealer 10 generally comprises a base 12 configured to support a container 100 or bag 150 (see Fig. 5 ) to be sealed, a body 20 extending generally perpendicular to the base 12 and a suction head 40 moveable relative to the body 20 for engagement with the container 100 or bag 150.
  • the base 12 includes a bottom plate 14 and an upper portion 24 which defines the support surface 16.
  • the upper portion 24 extends from and is integral with the body 20 although other configurations are possible.
  • a reference platform 18 extends from the bottom plate 14 and through the upper portion 24 such that the reference platform 18 extends above the support surface 16.
  • the reference platform 18 is aligned with the suction assembly 60 of the suction head 40 such that a valve assembly 130 of either a container 100 or bag 150 may be easily aligned with the suction assembly 60.
  • the user positions the bag with the valve assembly 130 positioned on the reference platform 18.
  • a target marking or the like may be provided on the reference platform 18.
  • FIG. 2 shows an exemplary container 100 confgured for use with the reference platform 18.
  • the container 100 has a hollow body 102 defined by sidewalls 104 extending from a bottom surface 108 and terminating in a rim 106 about an open end 107.
  • the bottom surface 108 has a concave central portion 110 from which an alignment projection 109 extends.
  • the alignment projection 109 has a rectangular perimeter which complements the configuration of the reference platform 18.
  • the reference platform 18 and alignment projection 109 may have other complimentary configurations, for example, circular, oval, pentagon etc.
  • the lid 120 of the container 100 has a skirt 124 depending from a top surface 122.
  • the skirt 122 extends to a lower rim 126 with a channel 128 thereabout.
  • An elastomeric sealing member 127 is positioned in the channel 128 and is configured to engage the rim 106 of the hollow body 102 to form a sealed connection between the lid 120 and the hollow body 102.
  • a valve assembly 130 extends through the top surface 122 and is positioned such that it is aligned with the alignment projection 109 when the lid 120 is positioned on the hollow body 102 such that the valve assembly 130 is aligned with the reference platform 18.
  • the valve assembly 130 includes a tubular member 132 which extends through the top surface 122 to define the passage therethrough.
  • the tubular member 132 extends above the top surface 122 although such may not be required.
  • An inward shoulder 134 of the tubular member 132 defines a seat about the through passage 135.
  • a valve member 138 is positioned within the tubular member 132 and includes a radially extending shoulder 136 configured to engage the seat and seal the through passage 135.
  • the valve member 138 is biased toward sealing engagement, however, upon application of a sufficient suction force, the valve member 138 moves away from the seat and a suction force may remove air from the hollow body 102 and create a vacuum therein. Once the suction force is removed, the valve member 138 is configured to automatically return to the seated position.
  • Other valve assemblies may be utilized in place of the described valve assembly 130.
  • a suction pump 30 and associated motor 28 are positioned within an internal chamber 26 of the body housing 22.
  • Tubing 32 extends between the suction pump 30 and a tee connector 37 while further tubing 34, 36 and 67 extends between the tee connector 37 and the suction assembly 60.
  • An exhaust tube 38 also extends from the suction pump 30 and is directed to a housing exhaust port (not shown).
  • a tube 39 also extends from the tee connector 37 to a pressure sensor 33. While tubing is described herein, it is understood that other mechanisms, for example, integral piping or the like, may be utilized.
  • the motor 28, suction pump 30 and the pressure sensor 33 are associated with a microcontroller 27 which is further associated with a manual activation switch 31 in the body 20 and an automatic switch 74 in the suction head 40.
  • the suction force is carried through tubes 32, 34, 36 and 67 to the suction assembly 60.
  • the pressure sensor 33 monitors the generated suction through tube 39 and once a desired level of vacuum has been achieved in the container or bag, the microcontroller 27 is configured to automatically deactivate the motor 28 and thereby the suction pump 30. In a preferred embodiment, the microcontroller 27 is further configured to automatically deactivate the motor 28 after a certain time period as a fail-safe mechanism.
  • the body 20 includes a vertical track 25 configured to guide a slide block 48 within a vertical slot 21 (see Fig. 3 ).
  • a wiper 23 or the like may extend across the vertical slot along the body housing 22 such that the vertical slot 21 is not externally visible.
  • a guide arm 46 extends between the guide block 48 and a head support platform 44.
  • the support platform 44 supports the suction assembly 60, the brake assemblies 80 and a liquid cup 78.
  • a housing member 42 is positioned on the support platform 44 to generally enclose the suction assembly 60 and the brake assemblies 80.
  • each brake assembly 80 controls movement of the support platform 44, and thereby the suction head 40, relative to the body 20.
  • Each brake assembly 80 includes a brake body 82 with a brake pad 84 positioned adjacent to a face 19 of the body housing 22.
  • a spring assembly including two springs 87 and a synchronizing plate 89 biases the brake pads 84 into engagement with the face 19 which locks the vertical position of the suction head 40 relative to the body 20.
  • Each brake assembly 80 includes a disengagement button 81 configured to be depressed to disengage the respective brake pad 84.
  • Each disengagement button 81 is aligned with a notch 86 in the respective brake body 82.
  • each disengagement button 81 is configured to engage a respective inclined surface 88 within the notch 86 such that as the button 81 is pushed into the notch 86, the inclined surface 83 engages the brake inclined surface 88 and pushes the respective brake pad 84 against the biasing force of the spring assembly and away from engagement with the face 19.
  • both buttons 81 depressed the suction head 40 may be moved vertically relative to the body 20.
  • the brake pads 84 automatically engage under the bias of the spring assembly and the vertical position of the suction head 40 is again locked.
  • the suction assembly 60 includes a vacuum chamber 62 supported by a moveable cup 63 which extends though the support platform 44 and is supported thereon by a radially outward rim 65.
  • the cup 63 is axially moveable toward the head housing 42, but is biased toward the seated position on the support platform 44 by a spring 76.
  • the vacuum chamber 62 includes a central inlet 66 which is surrounded by a downwardly extending sealing member 64.
  • the sealing member 64 has an inner diameter greater than the outer diameter of the valve tubular member 132 such that the sealing member 64 may receive the valve tubular member 132 and seal thereabout. With the sealing member 64 sealed about the valve tubular member 132, the valve assembly 130 is in sealed communication with the vacuum chamber 62.
  • the sealing member 64 engages a surface thereof and the vacuum chamber 62 and cup 63 are pushed into the suction head 40.
  • the cup 63 moves inward, it engages the automatic engagement switch 74, for example, a limit switch, and the microcontroller 27 activates the motor 28.
  • the spring 76 also biases the sealing member 64 toward the valve assembly 130, thereby maintaining a good seal between the suction assembly 60 and the container 100 or bag 150.
  • the vertical movement of the suction head 40 avoids the need for a user to hold the suction assembly 60 against the container or bag while vacuuming.
  • the suction force of the suction pump 30 is directed to a vacuum chamber outlet 68 such that the suction force passes through the chamber 62 and the central inlet 66 to the valve assembly 130.
  • a water flow mechanism 72 is positioned in the opposite end 70 of the vacuum chamber outlet 68. The water flow mechanism 72 is configured to signal the microcontroller 27 to shut off the motor 28, and thereby the pump 30, if liquid enters the vacuum chamber 62.
  • a liquid receiving chamber 78 is provided about the vacuum chamber 62. Any extracted liquid fills in the liquid receiving chamber 78, which can be removed and emptied after use.
  • the faces 19' of the body housing 20' define a corner configuration 17 adjacent the support surface 16' such that positioning of a bag 150 or container 100 into the corner configuration will align the valve assembly 130 with the suction assembly 60.
