Abstract: A bag is has an opening defined by a pair of walls and a pair of gussets. The walls are joined by the gussets. The bag has two slits. Each of the two slits is formed adjacent a wall and a gusset. Each of the two slits is adjacent the opening. A zipper comprises a pair of interlocking sections. The zipper is inserted through the slits. The interlocking sections are secured to at least a portion of each of the walls.

Abstract: A re-sealable bag (1) including a closure (13) is provided, which is sealed to the front wall (3) in the interior of the bag (1). The two-part closure (13) is sealed by the edges of the two closure parts (13a, 13b) to the internal face of the front wall (3) below the removal opening that is covered by a security strip (11). A cover sheet (15), which is sealed to the internal closure part (13a) and to the internal face of the front wall (3) above the opening, protects the closure (13) from coming into contact with the contents prior to the initial opening of the bag.

Abstract: A bag of paper or plastic with a grooved closure (111) fastened at the upper ends of the front and rear bag walls (103, 105) is provided. The closure is covered by a section (119) which projects beyond the rear bag wall (105) and which is applied over the closure (111). A breaking location is provided in the section (119) in order to create access to the grooved closure (111) or the contents of the bag.

Abstract: The invention relates to a closure (3) that comprises two interacting pairs of locking ribs (23, 33) that function in pairs. Said locking ribs (23, 33) are formed integrally with connecting strips (17, 21) in which guide ribs (27, 37) are configured which engage in a common glider (31). The closure (3) is opened by conical grooves (29, 39) inside the glider (31) which modify the distance between the two guide ribs (27, 37) by pushing apart and separating or reuniting and joining them.
