The present disclosure relates generally to a vacuum sealer home appliance and, more particularly, to a vacuum sealer with integrated, customizable heat stamping capability.
Vacuum sealers are small appliances, generally utilized to vacuum, i.e. evacuate air from, and heat seal plastic bags containing foodstuff for longer term storage. Vacuum sealing foodstuff packaging provides many benefits, with a particular advantage of preserving the freshness of the foodstuff for a longer period of time than if the foodstuff were otherwise stored while exposed to ambient air.
Despite the advantage of preserving the freshness of the foodstuff for a longer period of time, or because of the extended freshness, consumers get confused about the date on which the foodstuff contents were sealed, or, alternatively, identify a date by which to use, e.g., cook or consume, the foodstuff contents. Currently, a user must manually write the date onto the plastic bag, e.g., with a marker.
Accordingly, it would be advantageous to manufacture a vacuum sealer having the capability to also stamp a date to the plastic bag.
Briefly stated, one aspect of the present disclosure is directed to a vacuum sealer including a housing having an upper platform. A lid is pivotably attached to the housing, and movable between a closed position, covering the platform, and an open position, exposing the platform. The platform defines a first cavity and the lid defines an opposing second cavity in an underside of the lid, the first cavity and the second cavity being engaged in the closed position of the lid to form a sealed vacuum chamber therebetween. A pump is in fluid communication with the vacuum chamber to withdraw air from the vacuum chamber and create a vacuum therein, the sealed vacuum chamber being configured to receive an open end of a plastic bag therebetween and withdraw air therefrom via activation of the pump. A first heating plate is secured to one of the underside of the lid and the platform and an opposing, thermally insulating backing strip is secured to the other of the underside of the lid and the platform. The first heating plate and the backing strip are configured to heat seal a portion of a plastic bag positioned therebetween. A second heating plate is secured to one of the underside of the lid and the platform, and an opposing at least one selectively rotatable stamp wheel is rotatably mounted to the other of the underside of the lid and the platform. The at least one stamp wheel has a plurality of raised characters spaced about a periphery thereof, and the at least one stamp wheel and the second heating plate are configured to stamp the raised characters facing the second heating plate onto a portion of a plastic bag positioned therebetween.
Another aspect of the present disclosure is directed to a vacuum sealer comprising a housing having an upper platform and an internal compartment configured to house a roll of plastic bag stock therein. The compartment has an opening for accessing the roll of plastic bag stock therethrough. A door is pivotably mounted to the housing, the door being pivotable between a closed position, covering the opening, and an open position, enabling access to the compartment. The door includes a cutting bracket on an interior face thereof, an elongate track removably mounted upon the cutting bracket, a cutting blade holder slidably mounted upon the track and a cutting blade assembly mounted to the cutting blade holder. The cutting blade holder cantilevers forward from the track and includes a blade bracket at a terminal end thereof receiving the cutting blade assembly therein, such that the cutting blade is spaced forwardly from the track. A lid is pivotably attached to the housing, and movable between a closed position, covering the platform, and an open position, exposing the platform. The platform defines a first cavity and the lid defines an opposing second cavity in an underside of the lid, the first cavity and the second cavity being engaged in the closed position of the lid to form a sealed vacuum chamber therebetween. A pump is in fluid communication with the vacuum chamber to withdraw air from the vacuum chamber and create a vacuum therein, the sealed vacuum chamber being configured to receive an open end of a plastic bag therebetween and withdraw air therefrom via activation of the pump. A first heating plate is secured to one of the underside of the lid and the platform, and an opposing, thermally insulating backing strip is secured to the other of the underside of the lid and the platform. The first heating plate and the backing strip are configured to heat seal a portion of a plastic bag positioned therebetween.
The following description of the disclosure will be better understood when read in conjunction with the appended drawings. It should be understood, however, that the disclosure is not limited to the precise arrangements and instrumentalities shown. In the drawings:
Certain terminology is used in the following description for convenience only and is not limiting. The words “lower,” “bottom,” “upper” and “top” designate directions in the drawings to which reference is made. The words “inwardly,” “outwardly,” “upwardly” and “downwardly” refer to directions toward and away from, respectively, the geometric center of the vacuum sealer, and designated parts thereof, in accordance with the present disclosure. Unless specifically set forth herein, the terms “a,” “an” and “the” are not limited to one element, but instead should be read as meaning “at least one.” The terminology includes the words noted above, derivatives thereof and words of similar import.
It should also be understood that the terms “about,” “approximately,” “generally,” “substantially” and like terms, used herein when referring to a dimension or characteristic of a component of the invention, indicate that the described dimension/characteristic is not a strict boundary or parameter and does not exclude minor variations therefrom that are functionally similar. At a minimum, such references that include a numerical parameter would include variations that, using mathematical and industrial principles accepted in the art (e.g., rounding, measurement or other systematic errors, manufacturing tolerances, etc.), would not vary the least significant digit.
Referring to the drawings in detail, wherein like numerals indicate like elements throughout, there is shown in
A lid 16 at a top end of the upper housing 12 is movably attached thereto, and pivotable between closed (
The platform 20 defines a first cavity 22 bordered by a first gasket 22a secured on the platform 20. In the illustrated embodiment, the platform 20 is formed at an upper end of the upper housing 12, but the disclosure is not so limited. As should be understood, the platform 20 may be formed elsewhere on the vacuum sealer 10, such as, for example, without limitation, on a flange of the lower housing 14. The lid 16 defines a second cavity 24 formed in an underside thereof and bordered by a second gasket 24a secured to the underside of the lid 16. The first gasket 22a and the second gasket 24a are sized, shaped and positioned to sealingly, i.e., air-tightly, engage one another when the lid 16 is pivoted into the closed position thereof, such that the first cavity 22 and the second cavity 24 form an airtight vacuum chamber 26 therebetween. A vacuum pumping device 18 (
A lid handle 28 is mounted to the lid 16, e.g., to a front end of the lid 16, for a user to grasp and easily pivot the lid 16 between the open and closed positions, and, more importantly, to provide leverage for pressing the lid 16 down onto the platform 20 in the closed position to provide the required airtight seal between the first and second gaskets 22a, 24a. As shown best in
As should be understood, the platform 20 may alternatively include the at least one latching member 32 projecting therefrom and the lid 16 may include the corresponding at least one slot 34 having a latch therein. The release bar 33 may also be mounted to the lid 16. As also should be understood, the handle 28 and the release bar 33 may be combined into a single component. Alternatively, the lid 16 may be releasably fastenable/lockable to the platform 20 via any of numerous different means currently known or that later become known to those of ordinary skill in the art.
A conventional first heating plate 30, well known by those of ordinary skill in the art, is secured in/on the platform 20, adjacent, e.g., in front of, the first cavity 22. As should be understood, however, the heating plate 30 may be located elsewhere along the platform 20, or, alternatively, on the underside of the lid 16. As should be understood, the heating plate 30 includes a heating ribbon configured to heat up when electricity is applied thereto during a sealing operation to heat seal a bag. A corresponding backing strip/plate 31 is secured to the underside of the lid 16, opposite the first heating plate 30. As should be understood, the backing strip 31 may be formed of a thermal insulator, e.g., silicone, to prevent the heat from being transferred from the first heating plate 30 to the lid 16 and also to assist in the sealing operation. As also should be understood, the backing strip 31 may alternatively be located on the platform 20 opposite a heating plate 30 on the underside of the lid 16.

The vacuum sealer 10 further includes a user interface 40, which is operatively connected to a controller 56 (
As shown best in
The compartment 42 is accessible via a pivotable door 44 mounted to the lower housing 14 and movable between a closed position (
Referring to
A cutting blade holder 52 is slidably mounted upon the track 49 in a manner well understood by those of ordinary skill in the art. As one non-limiting example, the track 49 may define a front lip extending proximate a top and along a front edge of the track 49 and a rear lip extending proximate a top and along a rear edge of the track thereof. The cutting blade holder 52 may include a portion complementarily shaped to wrap around the top end of the track 49 and snap into abutment with the respective undersides of the front and rear lips of the track 49 such that cutting blade holder 52 is manually slidable back and forth along the track 49. As shown best in
As shown in
The first time the roll of plastic bag stock 50 is used, the track 49 is removed from the cutting bracket 48 (for example, as explained above) and an open, free end of the roll of plastic bag stock 50 is pulled out and extended beyond the cutting bracket 48. The track 49 is re-attached to the cutting bracket 48 such that roll of plastic bag stock 50 extends through an open-ended slot 51 between the cutting bracket 48 and the underside of the track 49. The free end of the roll of plastic bag stock 50 is then pulled as desired to form a bag of the desired size. The cutting blade holder 52 is then slid along the track 49 and the downwardly facing cutting blade assembly 54 cuts through the roll of plastic bag stock 50, creating a cut piece of bag stock having opposing open ends.
Advantageously, the forward cantilevered extension of the cutting blade holder 52 from the track 49 positions the cutting blade assembly 54 forward from the cutting bracket 48 and the track 49. Thus, the cutting blade assembly 54 cuts the plastic bag roll 50 at a location spaced forward from the cutting bracket 48 and the track 49. Consequently, after a length of the plastic bag is cut by the cutting blade assembly 54, a new free end of the plastic bag roll 50 (which extends between the cutting bracket 48 and the track 49) remains exposed (i.e., extending beyond the cutting bracket 48 and the track 49 approximately to the cutting blade assembly 54) and can be easily grasped and pulled out to a desired length in preparation for the next cut.
After the cut piece of bag stock is obtained, the lid 16 is moved to the open position thereof (if not already in the open position) and one of the open ends of the cut piece of bag stock is positioned atop the first heating plate 30 and the lid 16 is thereafter closed. The user interface 40 is actuated to initiate a “seal only” operation, whereby the first heating plate 30 is energized to heat up for a prescribed time or to a prescribed temperature or combinations thereof and seal the open end of the cut piece of bag stock pressed between the first heating plate 30 and the backing strip 31, thereby forming a plastic bag with one remaining open end for receiving the item(s), e.g., foodstuff therethrough. The plastic bag is removed from the vacuum sealer 10 and the item(s) is thereafter placed in the bag via the remaining open end. As should be understood, however, the vacuum sealer 10 may alternatively be utilized with a separately obtained plastic bag (not formed from the roll of plastic bag stock 50) having one open end.
Thereafter, the lid 16 is once again moved to the open position thereof (
To create a vacuum within the plastic bag, the pumping device 18 is energized (in a conventional manner well understood by those of ordinary skill in the art) to draw out air from the plastic bag via the open end thereof and through the aperture within the vacuum chamber 26. To seal the remaining open end of the plastic bag (after the removal of the air from the bag), the first heating plate 30 is then energized (in a conventional manner well understood by those of ordinary skill in the art) for a prescribed time or to a prescribed temperature or combinations thereof and seal the portion of the plastic bag pressed between the first heating plate 30 and the backing strip 31.
Prior to moving the lid 16 into the closed position, a user may also manually rotate the respective stamp wheels 36 to display a desired date, e.g., a “use by” date, and actuate the user interface 40 to initiate a “heat stamping” operation (in addition to the vacuum and/or sealing operations or alone). Upon pressing the lid 16 into the closed position thereof, the second heating plate 38 is energized, in a manner well understood by those of ordinary skill in the art, for a prescribed time or to a prescribed temperature or combinations, to create an embossed (or engraved) heat stamp of the selection on the portion of the plastic bag pressed between the stamp wheels 36 and the second heating plate 38.
It will be appreciated by those skilled in the art that changes could be made to the embodiment(s) described above without departing from the broad inventive concept thereof. As one example, the stamp wheel(s) 36 may be positioned along the backing strip 31, such that the stamp is embossed along the plastic bag seal, thereby eliminating the second heating plate 38. It is understood, therefore, that this disclosure is not limited to the particular embodiment(s) disclosed, but it is intended to cover modifications within the spirit and scope of the present invention, as set forth in the appended claims.
