One form of pharmaceutical packaging is a blister pack. A blister pack is comprised of a generally flat substrate on one side and a plurality of bubble like cavities on the other side. Within each cavity is stored a unit dose of a pharmaceutical such as a pill, tablet, or capsule. The contents within the cavity need not be pharmaceutical per se, however. When a consumer wishes to access the contents of a blister, he presses down on the cavity ‘bubble’ causing the contents to pierce the bottom surface (usually foil or the like) of the blister pack.
Blister packs are a convenient primary form of packaging. However, blister packs generally require a secondary form of packaging. The secondary form of packaging serves to protect the primary package as well as providing a convenient form for labeling. More importantly, however, the secondary packaging can also provide a means for securing the primary package from children as a safety feature since the contents of the primary packages can often be dangerous.
One of the safety measures associated with the secondary packaging is the ability to ‘lock’ and ‘unlock’ a primary package within a secondary package. Secondary packages have been comprised of many materials including paperboard packaging solutions and hard plastic shell type solutions. In general, the secondary packages receive a primary package and can securely seat it within a chamber such that it can not be withdrawn without manipulating a locking mechanism. A typical locking mechanism includes catches that prevent the primary package from being withdrawn unless a tab type mechanism can be separated from a tab catch mechanism.
Typical packaging solutions only accommodate a single primary package within a secondary package. In these solutions, the primary package itself is in a direct cooperative relationship with the secondary package. This can be inefficient if the contents of the primary package are used up rather quickly or if the primary package can only accommodate a relatively small number of discrete items.
Blister packs are not the only form of primary packaging that can be accommodated in the solutions described above. Such systems can protect primary packages that contain, for instance, medical devices such as syringes, dermal strip medications, liquid vials or ampules, etc. The primary package can be used to store and protect just about anything that can be retained by the relatively flat primary packaging medium.
What is needed is a single secondary packaging solution that can accommodate multiple primary packages in a secure child resistant manner.
SUMMARY OF THE INVENTIONIn one embodiment there is disclosed a packaging apparatus designed to accommodate a plurality of primary packages in a secure child-resistant manner. A plurality of primary packages for storing packaging contents each include at least one aperture. A secondary package houses the plurality of primary packages. A traveler mechanism is coupled with the plurality of primary packages and adapted to fit within the secondary package in a lockable slidable fashion. The traveler mechanism securely retains the plurality of primary packages.
The secondary package is comprised of plastic top and bottom portions that can be snap fit (or glued or otherwise adhered) together such that when fit together, the secondary package defines an interior chamber that is open on one end and closed on the opposite end. The secondary package is further comprises an elongated tapered stop on the interior surface of at least one of the top and bottom portions of the secondary package and at least one traveler stop on the interior surface of at least one of the top and bottom portions of the secondary package positioned near the open end of the interior chamber.
The secondary package further comprises a locking tab release positioned such that depressing the locking tab release while the traveler mechanism is in the locked position within the secondary package will cause the release tab stop of the traveler mechanism to clear the elongated tapered stop of the secondary package allowing the traveler mechanism to unlock and be slidably withdrawn from the secondary package.
The top and bottom portions of the secondary package further include a thumb/finger indent at the open end front edge to assist a person when grasping a primary package contained within the secondary package.
The traveler mechanism is comprised of top and bottom portions that can be snap fit (or glued or otherwise adhered) together such that when fit together, the traveler mechanism can be seated within the interior chamber of the secondary package in a lockable and slidable fashion. The traveler mechanism further comprises a flexible release tab that includes a release tab stop on at least one of the top and bottom portions of the traveler mechanism such that the release tab stop will abut the elongated tapered stop in a locked position that prevents the traveler mechanism from sliding outward. The traveler mechanism further comprises a flat surface adapted to engage the at least one traveler stop to prevent the traveler mechanism from being completely withdrawn from within the interior chamber of the secondary package and at least one post adapted to fit within the at least one aperture of the plurality of primary packages.
The present invention describes an improved packaging system comprised of a hard plastic shell secondary package adapted to receive and house a plurality of primary packages (such as, for instance, a plurality of blister packs) via a traveler mechanism. Rather than having the plurality of primary packages connect directly in a cooperative relationship with the secondary package, the plurality of primary packages are coupled with the traveling mechanism. The traveling mechanism is then coupled with the secondary package in a cooperative relationship that permits the traveler to be securely housed within the secondary package yet also allows the traveler mechanism to be substantially withdrawn to expose the contents of the primary packages.
For ease of description, the hard plastic shell may also be referred to as a sleeve package throughout this disclosure. The sleeve package is generally formed from two pieces of plastic (top and bottom) that snap fit to one another. Once fitted together, one end of the sleeve package remains substantially open and an interior chamber is formed that is adapted to receive and house a plurality of primary packages. There are one or more locking and unlocking mechanisms on and about the sleeve package and the traveler mechanism that operate to securely retain the plurality of primary packages within the sleeve package. To withdraw and expose the primary packages, a consumer must know how to operate the secondary package to release the locking mechanism(s). These locking mechanisms provide the entire packaging solution with an enhanced degree of child resistant safety features.
The traveler mechanism 200 is also comprised of a top piece 204 and bottom piece 206 and is shown assembled. In its assembled state, the traveler mechanism 200 is adapted to fit snugly yet slidably within the open end of the secondary package 100. The top piece 204 and the bottom piece 206 can share a common edge seam 202 and are generally snap fit together using a plurality of reciprocating connections. The edge seam 202 is not a requirement, however, meaning the top piece 204 and bottom piece 206 can be separate from one another and snap fit together. Also shown are a pair of posts 230 that are designed to accept the plurality of primary packages via apertures prior to snap fitting the top piece 204 to the bottom piece 206. A pair of primary packages 300 in the form of blister packs are also shown. The primary packages further include the aforementioned apertures 310 that fit over the posts 230 of the traveler mechanism 200.
The preferred method of constructing the entire packaging system first loops the primary packages 300 over the posts 230 of the traveler mechanism 200. The traveler mechanism 200 is then snap fit together to produce what is shown in
It should be noted that the locking mechanisms just described can be placed on the top portion of the packaging system, the bottom portion of the packaging system or on both the top and bottom portions of the packaging system.
To achieve the first purpose, the traveler mechanism 200 includes a pair of posts 230 that are adapted to fit within corresponding apertures 310 of the primary packages 300 to securely connect and retain the primary packages 300 to the traveler mechanism 200. Securing and retaining the primary packages 300 to the traveler mechanism 200 is a process that begins before the traveler mechanism is fully assembled as shown in
To achieve the second purpose, the traveler mechanism 200 has been constructed and shaped to fit within the chamber defined by the assembled secondary packaging 100. In one embodiment, the traveler mechanism 200 is comprised of two pieces that can be snap fit to one another to form the single mechanism. The two piece structure permits exposing the aforementioned posts 230 such that the primary package apertures 310 can be looped over the posts 230 before the traveler mechanism 200 is snap fit (or glued or otherwise adhered) together. The traveler mechanism 200 design allows the traveler mechanism 200 and primary packages 300 combination to be seated within the chamber defined by the assembled secondary packaging 100 such that it can slide back and forth within the chamber. There are components on both the traveler mechanism 200 and the secondary packaging 100 that cooperate at either end of the chamber. On the open end of the chamber, the traveler mechanism includes a flat surface 220 that will engage a traveler stop 110 on the secondary package 100 to prevent the traveler mechanism 200 (and primary packages 300) from being completely separated from the secondary packaging 100. On the closed end of the chamber, the traveler mechanism includes a combination flexible release tab 205 that includes a release tab stop 210 that can be depressed inward when an external force is applied. The combination flexible release tab 205 that includes a release tab stop 210 is designed to engage and cooperate with elongated tapered stop 130 that is part of the inner upper surface of the secondary packaging 100. As the traveler mechanism 200 slides further into the chamber of the secondary package 100 it eventually encounters the elongated tapered stop 130 and begins to depress inward as it rides up the tapered aspect of the elongated tapered stop 130. Once it clears the length of the elongated tapered stop 130 the combination flexible release tab 205 that includes a release tab stop 210 snaps back to its original position such that the release tab stop 210 abuts the non-tapered straight edge of the elongated tapered stop 130. In this ‘locked’ position, the traveler mechanism 200 can not be withdrawn (without unlocking) because the release tab stop 210 will engage the non-tapered straight edge of the elongated tapered stop 130 whenever the combination traveler mechanism 200 and primary packages 300 is attempted to be withdrawn.
While the traveler mechanism 200 (and secondary packaging 100) interaction above has been described as applied with respect to the top portion of the traveler mechanism 200, it may also be applied to the bottom portion of the traveler mechanism 200 either in lieu of the top portion or in addition to the top portion.
The description above has described a locking/release mechanism in which the traveler mechanism 200 is completely contained within the secondary package 100. An alternative embodiment is one in which the secondary package 100 includes an aperture rather than a locking tab release 120 and the release tab stop 210 on traveler mechanism 200 is inverted such that it protrudes from the aperture on the secondary package 100. In this embodiment, the user would apply an inward force on the inverted release tab stop to force it back within the interior chamber of the secondary package 100 to ‘unlock’ the packaging solution at which time the traveler mechanism 200 could be withdrawn from the secondary package to expose the attached primary packages 300.
The size and depth of the secondary package 100 and traveler mechanism 200 are generally a function of the number and depth of the primary packages 300. The greater the number of primary packages to be included in a packaging solution, the deeper the secondary package 100 and traveler mechanism 200.
It is believed that the present invention includes many other embodiments that may not be herein described in detail, but would nonetheless be appreciated by those skilled in the art from the disclosures made. Accordingly, this disclosure should not be read as being limited only to the foregoing examples or only to the designated preferred embodiments.
