CHILDPROOF BLISTER PACKAGING

Abstract: The childproof blister packaging consists of three portions formed from a single sheet. The blister pack is placed into the first portion having apertures which correlate with each respective cup on the blister pack. The second portion is then folded onto the top of the penetrable foil lid of the blister pack, and the third portion is then folded and sealed on top of the second portion. The second portion also has a plurality of moveable closures releasably secured in a plurality of slotted apertures. Each of the moveable closures is releasably secured in a first position, which blocks access to the outlet of each respective compartment of the blister pack, via breakable perforations. Access to the tablets can only be achieved by placing an elongate member, into the slotted aperture on the third portion and then pushingthe moveable closure on the second portion to a second position.

Description: CHILDPROOF BLISTER PACKAGING This invention relates to a childproof blister packaging. In particular, this invention relates to a childproof packaging for readily dispensing tablets or capsules to adults whilst preventing inadvertent access by children or other minors to said tablets or capsules stored in an appropriate blister pack. In recent years, childproof containers for protecting the inadvertent consumption of pharmaceutical products by children or other minors have become commonplace. Generally, these arrangements comprise of a container having a lid or closure which can only be removed by firstly depressing the lid or closure against a resilient locking mechanism. The strength of the locking mechanism is such that children or other minors are not able to release the lid or closure. Whilst these containers have proven popular, the increasing use of blister packs has reintroduced the danger of uncontrolled consumption of pharmaceutical products by children or other minors. The most common form of blister pack generally consists of a plastic base material having a plurality of cups or indentations into which the tablets are placed. A penetrable foil lid is then sealed to the base web and, in use, the tablets are simply pressed through the penetrable lid by the user. Whilst these blister packs provide a simple and convenient way to store and dispense medication, they are however open to potential misuse and inadvertent access by children. To increase child safety, simple techniques such as increasing the foil thickness have been proposed to make the opening of the pack more difficult. However, this can also cause problems to senior citizens or other adults suffering from physically debilitating disabilities, such as arthritis or rheumatism. It is the object of the present invention to provide a childproof blister packaging for readily dispensing tablets or capsules to adults whilst preventing inadvertent access by children or other minors.

In a preferred embodiment, said blank for forming a childproof packaging may be formed from a single sheet of suitable card or plastics material. In use, fold lines or lines of weakness are provided between the first and second panels and said second and third panels. Further preferably, the third panel having means for enabling access to each of said cover means on said second panel which may comprise a slotted aperture. Preferably, each of said cover means on said second panel comprises a slotted aperture having a moveable closure being releasably secured in a first position using a plurality of perforations. In use, user access to each respective compartment of said blister pack is achieved by pushing the moveable closure on the second panel through the third panel using any suitable elongate member such as, for example, a pen or key. The slotted aperture may also be closed by a tear-off portion for additional security. The advantages of the present invention are that a childproof blister packaging for readily dispensing tablets or capsules to adults whilst preventing inadvertent access by children or other minors, is provided. The childproof blister packaging enabling the secure storage of pharmaceutical products in a simple and economic package, which also provides for ease of assembly. The childproof blister packaging that can be easily used by senior citizens or other adults suffering from physically debilitating disabilities. It will be obvious to those skilled in the art that variations of the present invention are possible and this is intended that the present invention may be used other than as specifically described herein. A specific non-limiting embodiment of the invention will be described by way of example and with reference to the accompanying drawings in which: Figure 1 shows a plan view of a blank according to the present invention. Figure 2 illustrates a perspective view of the implementation of the present invention. Figure 3 shows a plan view of further detail of how the moveable closure locates in the closed position. Figure 4 illustrates a plan view of further detail of how the moveable closure locates in the open position. Figure 5 details how the user is allowed access to tablets or capsules by pushing the moveable closure using a suitable elongate member. Referring now to the drawings, a blank for forming the childproof blister packaging according to the present invention is illustrated in Figure 1. For reasons of clarity, a childproof packaging suitable for enveloping a blister pack having only a single row of tablets or capsules is described. However, in use, the present invention can be implemented for blister packs having a plurality of rows of tablets or capsules, or indeed any arrangement thereof. As shown in Figure 1 , the blank for forming the childproof blister packaging consists of three portions 1 , 2 and 3. In particular, the first portion 1 has a plurality of apertures 10 which correlate with each respective cup or compartment of the blister pack. In use, the first portion 1 is connected to the second portion 2 via fold line A. When assembled, the second portion 2 is located between the penetrable foil lid of the blister pack and the third portion 3. The second portion 2 having a plurality of moveable closures 14 being releasably secured in a plurality of slotted apertures 12. In use, each of the moveable closures 12 is releasably secured in a first position, which blocks access to the outlet of each respective compartment of the blister pack, via perforations which can only break under a suitable yield force. When assembled, the first portion 1 is also connected to the third portion 3 via fold line B. The third portion 3 is also folded on top of the second portion 2 and sealed with a suitable adhesive. In this way, access to the tablets or capsules held in the blister pack can only be achieved by placing an elongate member, such as a pen or key, into the slotted aperture 20 on the third portion 3 and then pushing the moveable closure 14 on the second portion 2 to a second position. At this point, apertures 10, 16 and 18 are all correlated and the penetrable lid of the blister pack is exposed. The user can then simply push the respective tablet or capsule through the penetrable foil lid. In use, the force that is required to displace the moveable closure 14 from its first position is determined by the number and thickness of the perforations connecting the moveable closure 14 to the second portion 2 inside slotted aperture 12. Generally speaking, the force required must be greater than that established by a child or other minor, although not too great as to preclude use by senior citizens or other adults suffering from physically debilitating disabilities. In this way, a child or other minor could not possess the sufficient skill, strength and dexterity required to manipulate the suitable elongate member and push the moveable closure 14 to a second position under a suitable yield force, through the slotted aperture 20 on the third portion 3. Figure 2 shows further detail of the implementation of the present invention and specifically how the childproof packaging envelops the blister pack. Again, only a single row of tablets or capsules on the blister pack is illustrated to improve the overall clarity. In use, the blister pack 22 is placed into the first portion 1 having apertures 10 which correlate with each respective cup or indentation on the blister pack 22. The second portion 2 is then folded, via line of weakness A, onto the top of the penetrable foil lid of the blister pack 22, and the third portion 3 is then folded on top of the second portion 2, via line of weakness B, and sealed with a suitable adhesive. The first 1 and third portions 3 then form the outer envelope of the childproof packaging, and access to the tablets held in the blister pack can only be made when apertures 10, 16 and 18 are all correlated. Further detail of the moveable closure 14 on the second portion 2 is detailed in Figures 3 and 4. Figures 3 and 4 depict the present invention partly assembled, with the first 1 and second portions 2 enveloping the blister pack 22. Figure 3 shows how the each of the moveable closures 14 are located in a first position which blocks access to the outlet of the respective compartments of the blister pack 22. Figure 4 illustrates how the uppermost moveable closure 14 on the second position 2 is located in second position, thereby enabling apertures 10 and 16 to correlate with the outlet of the penetrable lid of the blister pack 22, and thereby enabling the user to easily push a tablet therethrough. Of course, in use, the third portion 3 will be placed on top the second portion 2 and aperture 18 will also line up with aperture 10 on the first portion 1. Means for enabling access 20 to each of the moveable closures 14 on the second portion 2 consists of a plurality of slotted apertures 20 and a suitable elongate member can used to push the moveable closure 14 to its second position under a suitable yield force. This procedure is also illustrated in Figure 5, which shows a plan view of the present invention with the first, second and third portions 1 , 2 and 3 sealed. In use, the user inserts an elongate member, such as a pen or key, into the gap between slotted aperture 20 on the third portion 3 and tab 24 on the second portion 2. The user then pushes the moveable closure 14 over to its second position, wherein all three apertures 10, 16 and 18 correlate with each other and with the respective compartment of the blister pack. At this point, the user can then simply push the respective tablet or capsule through the penetrable foil lid. The slotted aperture 20 may also be covered by a tear-off portion formed in the third portion 3 for additional security. Various alterations and modifications may be made to the present invention without departing from the scope of the invention. For example, although particular embodiments refer to folding the first, second and third portions 1 , 2 and 3 from a single sheet to envelop the blister pack, this is in no way intended to be limiting as, in use, the present invention may be implemented using separate portions which are secured to one another using a suitable adhesive.
