Abstract
The present disclosure relates to plastic or polymeric container with reclosable zippers which make the package child-resistant. In one typical embodiment, this is achieved by a zipper with a high internal opening force and a low external opening force, wherein three flanges are sealed to the bag walls, and one external flange is left unsealed. In order to encounter the low external opening force, the user must grab the unsealed external flange while applying an external opening force to the zipper.
Claims12
A container or bag, including:
- a first wall and a second wall, the first wall and the second wall being joined together so as to form a storage volume therebetween and a mouth;
- a zipper attached to the first wall and second wall, thereby making the mouth reclosable, and defining an inside of the container or bag oriented toward the storage volume and an outside of the container or bag oriented toward the mouth, the zipper including:
- a first profile including a first interior flange, a first interlocking element and a first exterior flange;
- and
- a second profile including a second interior flange, a second interlocking element and a second exterior flange, the second exterior flange having sufficient length to include a manually grippable portion;
- wherein the first interior flange is attached to the first wall on an inside of the container or bag, the second interior flange is attached to the second wall on an inside of the container or bag;
- and
- wherein the second wall extends beyond the second exterior flange, the second exterior flange being unattached to the second bag wall, whereby opening forces applied to the outside of the second wall of the package or bag are transmitted to the second interior flange and to the interior of the first and second interlocking elements whereby increased interior opening forces are encountered, thereby resisting access to the interior of the bag, and whereby opening forces applied to the manually grippable portion of the second exterior flange are transmitted to the first and second interlocking elements whereby decreased exterior opening forces are encountered.
