Bag closing device

Abstract

A bag closing device may include an upper surface, a lower surface opposite the upper surface, and a peripheral surface between the upper surface and the lower surface. The peripheral surface may define a first opening and a second opening. The bag closing device may include a first set of protrusions extending into the first opening and a second set of protrusions extending into the second opening.

What is claimed is: 
     
         1 . A bag closing device comprising:
 an upper surface;   a lower surface opposite the upper surface;   a peripheral surface between the upper surface and the lower surface, wherein the peripheral surface defines a first opening and a second opening;   a first set of protrusions extending into the first opening; and   a second set of protrusions extending into the second opening.   
     
     
         2 . The bag closing device of  claim 1 , further comprising:
 a third set of protrusions extending into a third opening, the third opening defined by the peripheral surface.   
     
     
         3 . The bag closing device of  claim 1 , further comprising:
 a fourth set of protrusions extending into a fourth opening, the fourth opening defined by the peripheral surface.   
     
     
         4 . The bag closing device of  claim 1 , further comprising:
 a fifth set of protrusions extending into a fifth opening, the fifth opening defined by the peripheral surface.   
     
     
         5 . The bag closing device of  claim 1 , wherein the peripheral surface includes one or more recesses. 
     
     
         6 . The bag closing device of  claim 1 , wherein at least one of the first opening or the second opening is primarily circular. 
     
     
         7 . The bag closing device of  claim 1 , wherein the first set of protrusions extends from the peripheral surface into the first opening and the second set of protrusions extends from the peripheral surface into the second opening. 
     
     
         8 . The bag closing device of  claim 1 , wherein each protrusion of the first set of protrusions extends towards a center of the first opening and each protrusion of the second set of protrusions extends towards a center of the second opening. 
     
     
         9 . The bag closing device of  claim 1 , wherein each protrusion of the first set of protrusions extends a different distance into the first opening and each protrusion of the second set of protrusion extends a different distance into the second opening. 
     
     
         10 . The bag closing device of  claim 1 , wherein the first set of protrusions and the second set of protrusions include at least four protrusions. 
     
     
         11 . The bag closing device of  claim 1 , wherein the first set of protrusions has variable spacing and the second set of protrusions has variable spacing. 
     
     
         12 . The bag closing device of  claim 1 , wherein the first set of protrusions has equivalent spacing and the second set of protrusions has equivalent spacing. 
     
     
         13 . The bag closing device of  claim 1 , wherein the first set of protrusions and the second set of protrusions include teeth. 
     
     
         14 . The bag closing device of  claim 1 , wherein the first set of protrusions and the second set of protrusions include hooks. 
     
     
         15 . The bag closing device of  claim 1 , further comprising a handle connected to the upper surface. 
     
     
         16 . The bag closing device of  claim 1 , wherein the first opening is on one side of the bag closing device and the second opening is on an opposite side of the bag closing device. 
     
     
         17 . The bag closing device of  claim 1 , wherein the first opening and the second opening are on one side of the bag closing device. 
     
     
         18 . The bag closing device of  claim 1 , further comprising a tether connected to the upper surface of the bag closing device.
