Adhesive closure strip

Abstract

A pair of closure strips for resealing bags, the pair of closure strips comprising a first closure strip comprising a substrate including a grip strip, a groove strip, and an adhesive region, the groove strip. The pair of closure strips further comprising a second closure strip comprising a substrate including a grip strip, a stem strip, and an adhesive region. The stem strip comprises a stem structure that interlocks with a groove of the groove strip. The first closure strip and the second closure strip are attached to a bag by adhering the adhesive region of the first closure strip and the adhesive region of the second closure strip to sidewall regions adjacent to an opening of the bag.

 a first closure strip comprising a substrate including a grip strip, a groove strip, and an adhesive region, the adhesive region of the first closure strip defining a first adhesive surface the   a second closure strip comprising a substrate including a grip strip, a stem strip, and an adhesive region, the first closure strip and the second closure strip being separate and discrete elements from each other and configured for removable attachment to each other, the adhesive region of the second closure strip defining a second adhesive surface, the second adhesive surface being oriented in an opposing direction to the first adhesive surface when the first and second closure strips are attached together such that a normal of the first adhesive surface extends through the second adhesive surface and a normal of the second adhesive surface extends through the first adhesive surface;   wherein the stem strip comprises a stem structure that interlocks with a groove of the groove strip to at least partially attach the first and second closure strips together; and   the first closure strip and the second closure strip being discrete elements from a bag, the bag comprising first and second sidewall regions forming an opening therebetween, the first closure strip being configured for attachment to the bag by adhering the adhesive region of the first closure strip to the first sidewall region adjacent the opening such that the grip and groove strips of the first closure strip are disposed outside of the opening of the bag and the second closure strip being configured for attachment to the bag by adhering the adhesive region of the second closure strip to the second sidewall region adjacent to the opening such that the grip and stem strips of the second closure strip are disposed outside of the opening of the bag.   
     
     
         2 . The pair of closure strips of  claim 1  wherein the groove strip is on an inner-facing side of the first closure strip and the stem strip is on an inner-facing side of the second closure strip. 
     
     
         3 . The pair of closure strips of  claim 1  wherein each of the first closure strip and the second closure strip further comprises a grip strip. 
     
     
         4 . The pair of closure strips of  claim 3  wherein the grip strip provides improved ease of holding a top section of the closure strip. 
     
     
         5 . The pair of closure strips of  claim 3  wherein the grip strip comprises a plurality of elongated generally parallel ridges spaced apart in parallel relationship and horizontally extending from substantially a first edge of the closure strip to a second edge of the closure strip. 
     
     
         6 . The pair of closure strips of  claim 1  wherein the substrates of the first closure strip and the second closure strip comprise a sheet material including paper or plastic film. 
     
     
         7 . The pair of closure strips of  claim 1  wherein the first closure strip and the second closure strip are pre-attached and wound into a spool. 
     
     
         8 . The pair of closure strips of  claim 1  wherein the first closure strip and the second closure strip are perforated at set lengths. 
     
     
         9 . The pair of closure strips of  claim 1  wherein the first closure strip and the second closure strip are precut in various lengths. 
     
     
         10 . The pair of closure strips of  claim 1  wherein the adhesive region of the first closure strip and the adhesive region of the second closure strip are adhered to sidewall regions below the opening of the bag. 
     
     
         11 . The pair of closure strips of  claim 1  wherein the first closure strip and the second closure strip are attached to the bag such that the opening of the bag is below the groove strip and the stem strip. 
     
     
         12 . The pair of closure strips of  claim 1  wherein the groove strip is located in a midsection region of first closure strip above the adhesive region of the first closure strip. 
     
     
         13 . The pair of closure strips of  claim 1  wherein the stem strip is located in a midsection region of second closure strip above the adhesive region of the second closure strip. 
     
     
         14 . The pair of closure strips of  claim 1  wherein the groove strip is on an inner-facing side of the first closure strip and the stem strip is on an inner-facing side of the second closure strip. 
     
     
         15 . The pair of closure strips of  claim 1  wherein the adhesive region of the first closure strip is on an inner-facing side of the first closure strip and the adhesive region of the second closure strip is on an inner-facing side of the second closure strip. 
     
     
         16 . The pair of closure strips of  claim 1  wherein the adhesive region of the first closure strip is on an outer-facing side of the first closure strip and the adhesive region of the second closure strip is on an outer-facing side of the second closure strip. 
     
     
         17 . The pair of closure strips of  claim 16  wherein:
 the adhesive region the first closure strip is configured for attachment to the bag by adhering the adhesive region of the first closure strip to an interior portion of the first sidewall region adjacent to the opening of the bag; and 
 the adhesive region the second closure strip is configured for attachment to the bag by adhering the adhesive region of the second closure strip to an interior portion of the second sidewall region adjacent to the opening of the bag. 
 
     
     
         18 . The pair of closure strips of  claim 17  wherein the adhesive region of the first closure strip faces away from the adhesive region of the second closure strip when the first and second closure strips are attached to the bag. 
     
     
         19 . The pair of closure strips of  claim 1  wherein:
 the adhesive region of the first closure strip faces in an opposing direction to the groove strip; and 
 the adhesive region of the second closure strip faces in an opposing direction to the stem strip. 
 
     
     
         20 . The pair of closure strips of  claim 1  wherein, when detached from each other, each of the first closure strip and the second closure strip are configured for separate and individual attachment to the bag.
