Closure device

A reclosable bag, the reclosable bag comprising:

• a first wall and a second wall, the first and second wall being configured to form a product pouch and a mouth configured to be selectively closable, wherein the mouth allows product to be inserted into and removed from the product pouch of the reclosable bag;
• a zipper comprising a first profile and a second profile, wherein the first and second profile are configured to be selectively interlocked with each other to close the mouth of the reclosable bag, each profile having a length and a longitudinal axis extending along the length;
• and
• a plurality of impressions formed into the first profile along a length of the zipper, the plurality of impressions including a first set of impressions and a second set of impressions, the first set of impressions extending transversely of the first profile longitudinal axis and defining a first skew angle with respect to the longitudinal axis of the first profile, the first set of impressions being located at spaced apart locations over the entire length of the first profile, the second set of impressions extending transversely of the first profile longitudinal axis and defining a second skew angle with respect to the longitudinal axis of the first profile, the second skew angle being skewed oppositely of the first skew angle with respect to a transverse axis of the first profile that is perpendicular to the longitudinal axis of the first profile, the second set of impressions being located at spaced apart locations over the entire length of the first profile, wherein at least some first impressions of the first set of impressions are spaced apart from nearest adjacent second impressions of the second set of impressions along the longitudinal axis of the first profile;
• a plurality of impressions formed into the second profile along a length of the zipper, the plurality of impressions including a first set of impressions and a second set of impressions, the first set of impressions extending transversely of the second profile longitudinal axis and defining a first skew angle with respect to the longitudinal axis of the second profile, the first set of impressions being located at spaced apart locations over the entire length of the second profile, the second set of impressions extending transversely of the second profile longitudinal axis and defining a second skew angle with respect to the longitudinal axis of the second profile, the second skew angle being skewed oppositely of the first skew angle with respect to a transverse axis of the second profile that is perpendicular to the longitudinal axis of the second profile, the second set of impressions being located at spaced apart locations over the entire length of the second profile.

A method of making a reclosable bag, the method comprising:

• forming a product pouch from a first wall and a second wall, wherein the first and second walls are connected at a bottom, a first side and a second side and define a mouth on a top side providing access to the product pouch;
• providing a zipper configured to releasably close the mouth, the zipper comprising a male profile and a female profile configured to be selectively interlocked with each other to close the mouth of the reclosable bag;
• and
• forming the male profile of the zipper using a former to create a row of impressions immediately over and extending into the male profile, at least some of the impressions being arranged in a first orientation and others of the impressions being arranged in a second orientation different from the first orientation, at least some of the impressions of the first orientation being spaced apart from the nearest adjacent impression of the second orientation;
• forming the female profile of the zipper using the former to create a row of impressions immediately over and extending into the female profile.
