Reclosable bag with tear open feature

Abstract

A reclosable back-seam bag having a top seal and a bottom seal, and a front wall and a back wall is disclosed. The front wall is joined to the back wall at the top seal and the bottom seal. The reclosable back-seam bag includes a reclosable fastener that includes two ends, a first continuous elongated profile strip having a front wall connecting flange and a second continuous elongated profile strip having a back wall connecting flange. The first continuous elongated profile strip includes a male interlocking profile having at least one male interlocking member, and the second continuous elongated profile strip includes a female interlocking profile having at least one female interlocking member. The male interlocking member is configured so as to cause the male interlocking profile to be separated from the female interlocking profile with a substantially equal opening force when being separated in a direction toward said top seal as when separated in a direction toward said bottom seal. At least one frangible access portion disposed substantially parallel to said reclosable fastener assembly may be provided to expose the releasable fastener assembly and/or the contents of the bag.

Benefits of technology

[0016]In another example, a first continuous elongated profile strip having a male interlocking profile includes at least one male interlocking member. Also provided is a second continuous elongated profile strip having a female interlocking profile that includes at least one female interlocking member. The first continuous elongated profile strip can be releasably connected to the second continuous elongated profile strip by engaging the male interlocking member with the female interlocking member. However, in a preferred e

Problems solved by technology

A particular problem with the Ramsey '122 technique is that a greater amount of force is required to open the reclosable fasteners from outside the bag than the amount of force required to tear open the bag from the middle.

Such disproportionate amount of force may damage the reclosable bag or even the contents of the reclosable bag when a user opens the bag.

Hence, the user will have to become accustomed to an unfamiliar or u
