TAMPER/CHILD RESISTANT BAG
A child-resistant tamper-resistant bag is provided, of the type which may be used for prescription medicine and other products. The bag includes front and rear walls with a product-side-only opening zipper which defines a product compartment within the bag. The mouth of the bag includes a one-time close-only zipper thereby allowing a pharmacist or other person to easily and securely fill the bag with product and securely close the bag. A line of perforations or other line of weakness may be provided between the two zippers, in order to provide consumer access to the product-side-only opening zipper. The consumer then grasps the walls of the bag on the product side of the product-side-only opening zipper and pulls the walls away from each other thereby opening the product-side-only opening zipper and providing access to the product compartment.

This application claims priority under 35 U.S.C. §119(e) of U.S. provisional patent application Ser. No. 61/513,001 filed on Jul. 29, 2011, the contents of which are hereby incorporated by reference in their entirety.
BACKGROUND OF THE DISCLOSURE1. Field of the Disclosure
The present disclosure relates to a child-resistant bag or a tamper-resistant bag wherein a one-time close-only zipper is provided near the opening of the bag, and one or more additional zippers which can be opened only from the inside of the bag (that is, the user pulls apart the bag walls from the product side of the zipper) are provided in the interior of the bag to define a product compartment.
2. Description of the Prior Art
The need for child-resistant and tamper-resistant bottles for medicine and similar substances is self-evident and well-established. In the prior art, representative examples of child-resistant or tamper-resistant pill or medicine bottles can be found in U.S. Pat. No. 5,938,055 entitled “Safety Cap and Container”, issued on Aug. 17, 1999 to Philips et al. and U.S. Pat. No. 5,449,078 entitled “Combination of a Container and a Safety Cap Therefor”, issued on Sep. 12, 1995 to Akers.
However, such prior art pill bottles are expensive to produce. Additionally, there is the land fill issue. Billions of prescriptions are filled every year in the United States and throughout the world. These bottles, when discarded, take up a substantial volume in land fills. Likewise, this substantial volume adds to manufacturing and transportation costs. Additionally, many prior art pill bottles, with caps, include more than one material thereby increasing recycling costs.
OBJECTS AND SUMMARY OF THE DISCLOSUREIt is therefore an object of the present disclosure to provide a tamper-resistant, child-resistant container which provides the advantages of prior art bottles, but which has reduced manufacturing, transportation and recycling costs.
This and other advantages are attained by providing a flexible polymer bag or package with at least two zippers. The first zipper, placed more closely to the mouth of the bag, is a one-time close-only zipper. The second zipper (which may be replaced by a plurality of similar zippers) is further away from the mouth of the bag than the first zipper, and is designed to be opened only by pulling on the bag walls on the product side of the package rather than on the bag walls on the consumer side of the package. Additionally, a perforated line or other line of weakness may be provided in the bag walls between the two zippers in order to provide initial access to the bag and further to provide tamper evidence.
Further objects and advantages of the disclosure will become apparent from the following description and from the accompanying drawings, wherein:
Referring now to the drawings in detail wherein like numerals indicate like elements throughout the several views, one sees that
Additionally, inwardly from the one-time close-only zipper 26 is product-side-only opening zipper 28 thereby defining a product area 30 between bottom seal 16 and zipper 28, and likewise bounded by first and second side seals 18, 20. Such a product-side-only opening zipper 28, typically made of polymeric material, can be opened only by grabbing or pinching the front and rear walls 12, 14 in the product area 30 and pulling the walls 12, 14 apart thereby opening the zipper 28. If a child or other person tried to open the zipper 28 by grabbing or pinching the walls 12, 14 on the consumer side, outside of the product area (i.e., in the orientation of
Optionally, first and second gussets 19, 21 may be placed on the sides of the bag 10, proximate to side seals 18, 20, respectively, to allow the bag 10 to stand upright, as may be desired when the consumer places the bag 10 in a medicine chest or similar location. First and second gussets 19, 21 are illustrated as extending the entire height of bag 10, but may likewise be formed only below product-side-only opening zipper 28.
A line of perforations 29, or other line of weakness (such as, but not limited to, laser scoring), may be provided on one or both of front and rear walls 12, 14, between and parallel to zippers 26, 28, to provide for initial tamper-evident consumer access to the product-side-only opening zipper 28 after one-time close-only zipper 26 has been closed (typically by, but not limited to, a pharmacist).
The bag 10 is typically manufactured with zippers 26 and 28 open or not interlocked. The pharmacist or similar person places the medicine (such as pills) or other product within the product area 30 of bag 10 and, first, closes product-side-only opening zipper 28 and then closes one-time close-only zipper 26. The consumer then receives the bag 10 at the pharmacy or other location, and typically takes the bag 10, including medicine, home or to some other location. The consumer then either opens the line of perforations 29 (or other line of weakness) or cuts the front and/or rear wall 12, 14 at a location between the zippers 26, 28. In some embodiments, if the line of perforations 29 (or other line of weakness) is formed in both the front and rear walls 12, 14, then the portion of the bag 10 above the line of perforations 29 may be removed. The consumer then grasps the front and rear bag walls 12, 14 on the product side of zipper 28, within product area 30 and pulls front and rear walls 12, 14 apart thereby opening zipper 28 and providing access to the medicine in product area 30. The user then takes the appropriate amount of medicine, such as, but not limited to, pills, from the product area 30 and recloses zipper 28 until the next dose is required.
Thus the several aforementioned objects and advantages are most effectively attained. Although preferred embodiments of the invention have been disclosed and described in detail herein, it should be understood that this invention is in no sense limited thereby and its scope is to be determined by that of the appended claims.
