Hand warmer with a sealable end
View Patent ↗A hand warmer is disclosed herein. The hand warmer has a central pocket defined by a cylindrical housing and a sealing member proximate an anterior end of the housing, wherein the sealing member is configured switch positions from a closed position to an open position with an application of a pulling or pushing force by the user in a direction parallel an arm of the user. A method of warming a user's hands is also provided.
1. A hand warmer comprising:
a central pocket defined by an approximately cylindrical housing; and
a sealing member proximate an anterior end of the approximately cylindrical housing, wherein the sealing member is configured to switch positions from a closed position to an open position with an application of a pulling or a pushing force by the user in a direction parallel to an arm of the user;
wherein the sealing member comprises a series of magnets disposed within the central pocket, wherein the series of magnets comprise a first magnet having a first polarity disposed on a top interior edge, and a second magnet having an opposite polarity disposed opposite the first magnet on a bottom interior edge, such that the top and bottom adjacent ends are pulled closed by first and second opposing polarities.
2. The hand warmer of claim 1 , wherein the series of magnets comprise magnetic strips.
3. The hand warmer of claim 1 , further comprising an annular space defined between an exterior of the approximately cylindrical housing and an interior of the approximately cylindrical housing, wherein:
an insulating material is disposed in the annular space; and
the sealing member is disposed in the annular space.
4. The hand warmer of claim 1 , further comprising a cuff positioned proximate to a posterior section of the hand warmer, the cuff being configured to form a seal around an arm of the user.
5. The hand warmer of claim 1 , further comprising a heat source disposed therein, wherein the heat source is disposed in a pocket defined in the interior of the central pocket.
6. A method of warming a user's hand, the method comprising:
providing a central pocket defined by an approximately cylindrical housing dimensioned to fit the hand of the user; and
automatically sealing an end of the central pocket when the approximately cylindrical housing is pushed up an arm of the user to the user's hand and past the user's fingers;
wherein the sealing of an end of the central pocket comprises disposing a series of magnets within the central pocket, wherein the series of magnets comprise a first magnet having a first polarity disposed on a top interior edge, and a second magnet having an opposite polarity disposed opposite the first magnet on bottom interior edge such that the top and bottom adjacent ends are pulled closed by the first and second opposing magnets.
7. The method of claim 6 , wherein the series of magnets comprise magnetic strips.
8. The method of claim 6 , further comprising providing an annular space defined between an exterior of the housing and an interior of the housing, wherein:
an insulating material is disposed in the annular space; and
the sealing member is disposed in the annular space.
9. The method of claim 6 , further comprising sealing a posterior section of the hand warmer using a cuff, the cuff being configured to form a seal around the arm of the user.
10. The method of claim 6 , further comprising heating the central pocket using a heat source disposed therein, wherein the heat source is disposed in a pocket defined in the interior of the central pocket.
