Abstract
A box sealing apparatus on which a box with the bottom flaps folded is positioned on an anvil-type holder supported on a moveable arm. The folded box is then manually pushed into contact with a sealing mechanism. The sealing mechanism has a contacting face that is angularly displaced from the horizontal so that the anvil-type holder has an identical angular position when the anvil holder contacts the contacting face. After the box flaps are sealed, the holder with the sealed box thereupon is returned to the operator by gravitational force for removal of the sealed box.
Claims4
A box sealing machine comprising:
- a frame means for supporting said box sealing machine, said frame means having a lower portion and an upper portion,
- a sealing means adjustably connected to said upper portion of said frame for fastening one end of an inverted box into a closed position,
- a pivotal arm having a first end movably connected to said lower portion of said frame and a distal end,
- a platform means for supporting and positioning the inverted box, said platform means connected to said distal end,
- said pivotal arm and said platform means having a load position and a sealing position,
- said platform means is sized and shaped to receive the inverted box from an operator in said load position and fix the position of the inverted box relative to said platform means,
- said pivotal arm and said platform means positioned near the operator in said load position,
- said pivotal arm means including means for allowing movement to and return from said sealing position by the operator initially pushing the inverted box and said platform means toward said sealing means,
- said platform means sized and positioned to stop and position the inverted box on said platform means in contact with the sealing means without aid of the operator, after the initial push,
- said sealing means actuated by said inverted box and said platform means engaging said sealing means,
- said sealing means positioned substantially parallel to said inverted box on said platform means when stopped and sealed by sealing means in said sealing position.
