Description
- The present invention relates to blister packaging designed to distribute products such as pharmaceutical drugs and the method of removing the contents of such packaging. More particularly, the present invention relates to blister packaging designed to distribute pharmaceutical drugs that provide difficult access for a child. The present invention is ideally suited for use with pharmaceutical drugs, but may be used to distribute any product that may be contained within blister packaging.
- Individual packages for medicaments are well know in the art and are typically provided as physician samples, dose prescriptions, over-the-counter pharmaceuticals, and the like as is well known in the trade. Such packaging usually contains medicaments which may be harmful, if ingested by a young child.
- Accordingly, the problem associated with the use of such packages is the ease in which the packaging may be opened by small children as a result of insufficient resistance. Thus, there has been a need for a blister package, which would eliminate the problems associated with the prior packages discussed above.
- It has been found that a blister packaging particularly suited for packaging at least one medicament can be constructed in accordance with the present invention. In addition, the blister packaging of the present invention is resistant to being opened by children by increasing the difficulty of opening, while still being easily opened by adults.
- The present invention provides a child resistant blister packaging for containing at least one medicament or the like having an upper cover sheet with at least one aperture, a bottom backing card with at least one scored exit port, and a blister laminate situated between the cover sheet and the backing card, the blister laminate including a blister sheet having at least one blister containing a cavity for receiving a pill and a layer adhered to the a bottom surface of the blister sheet. The blister protrudes through the aperture in the cover sheet and is arranged on a carrier tab that will not line up in registry with the scored exit port in the backing card unless a force is applied to the blister to sever a connection means holding the carrier tab in place. Upon separating the connections means, the blister can be moved to align the pill-receiving cavity with the scored exit port and the blister can be collapsed to force a medicament stored in the cavity through the bottom layer of the blister laminate and the scored exit port.
- It is, therefore, an important object of the present invention to provide a package construction of the type described which is child resistant while still being easily opened by adults.
- It is yet another object of the present invention to provide a method of removing the contents from a child resistant blister packaging that is easily performed by adults, but difficult to accomplish by children.
- It is a further object of the present invention to provide a packaging having a rigid cover sheet and backing card, and a blister having a lateral protrusion to enable a user to properly grip the packaging when attempting to remove the contents of the blister.
- It is a further object of the present invention to provide a packaging having an aperture in the cover sheet to guide a blister protruding through the aperture along an arcuate path, and a resilient deformation neck to provide spring-like resistance to the movement of the blister.
- It is another object of the present invention to provide a packaging wherein the connections means holding the carrier tab in place is a short, thin strip of material formed from the blister laminate.
- It is yet another object of the present invention to provide a packaging wherein an elevated rib is formed parallel and adjacent to an edge of the deformation gap to create a stop for the carrier tab.
- It is a further object of the present invention to provide a package construction having the advantageous characteristics mentioned in the preceding paragraph, which is simpler in structure and more economical in manufacture, and staunch, durable and reliable to effectively protect the contents, resist unauthorized tampering, and otherwise accomplish its intended objects.
- Other objects of the present invention will become apparent upon reading the following specification and referring to the accompanying drawings, which form a material part of this disclosure.
- The invention accordingly comprises the features of construction, combinations of elements, and arrangements of parts, which will be exemplified in the construction hereinafter described, and of which the scope will be indicated by the appended claims.

FIG. 7 is an enlarged fragmentary perspective view of the blister packaging of the present invention showing a collapsed pill-receiving cavity, a ruptured foil layer, and a ruptured scored exit port. - The child resistant blister packaging of the present invention for containing at least one medicament or the like, includes an upper cover sheet having at least one aperture, a bottom backing card having at least one generally square-shaped scored exit port, and a blister laminate situated between the cover sheet and the backing card, the blister laminate includes a sheet with a top surface having at least one blister containing a cavity for receiving a pill and a foil layer adhered to the a bottom surface of the sheet. The blister containing the pill-receiving cavity protrudes through the aperture in the cover sheet and is arranged on a generally square-shaped carrier tab that will not align in registry with the scored exit port in the backing card unless a force is applied to the pill-receiving cavity to sever a connection means holding the carrier tab in place. The carrier tab is punched into the blister laminate along with a deformation neck and a deformation gap. Upon separating the connections means, the pill-receiving cavity can be moved to align with the scored exit port by moving the carrier tab across the deformation gap and the blister containing the pill-receiving cavity can be collapsed to force the medicament through the foil layer and the scored exit port.
- Referring now more particularly to the drawings, and specifically to
FIG. 1 thereof, there is illustrated therein a sectional view demonstrating the various layers of the present invention. - The top layer of the child
resistant blister packaging 10 is acover sheet 12 bonded to the bottom layer, which is abacking card 18, at adhesive lines or heat sealedlines 20. Any other method known to those skilled in the art that will secure thecover sheet 12 to thebacking card 18 is also acceptable. Thecover sheet 12 includes at least oneaperture 22, and preferably a plurality ofapertures 22. Both thecover sheet 12 and thebacking card 18 are preferably made of a relatively rigid plastic material - A
blister laminate 14 is disposed betweencover sheet 12 and thebacking card 18. Theblister laminate 14 is securely pressed between the two layers so that theblister laminate 14 remains stationary. Again, any method known to those skilled in the art that will secure theblister laminate 14 between the top and bottom layers of theblister packaging 10 is acceptable. Theblister laminate 14 has at least two layers, ablister sheet 15 and arupturable layer 16. Theblister sheet 14 is formed from a flat, preferably clear plastic sheet of suitable transparent thermoplastic polymer which has been thermoformed or die-molded to form at least oneblister 19 beneath which is a pill-receivingcavity 24 in the top surface of theblister sheet 15. The thermoplastic polymer must be weak enough so that theblister 19 containing the pill-receivingcavity 24 is collapsible if sufficient force is applied to the top of theblister 19 by manually pressing the same by a user's thumb or the like. Therupturable layer 16 is bonded to the bottom surface of theblister sheet 15. Theblister 19 protrudes through theaperture 22 in thecover sheet 12. Therupturable layer 16 can comprise a plurality of layers, as long as the material is able to seal the pill-receivingcavity 24 and only rupture upon the application of force against the upper surface of theblister 19 by a user. Therupturable layer 16 is preferably thin, metallic foil. The pill-receivingcavity 24 can optionally include a lateral protrusion in the form of alip 26. Thelip 26 is slightly curved to accommodate the tip of a finger or thumb. The curved surface area of thelip 26 evenly distributes the force exerted on the side of theblister 19 which is the first step in removing the contents of the packaging, as will be described in greater detail below. - Referring now to
FIG. 2 , there is illustrated a plan view of the childresistant blister packaging 10 demonstrating a plurality of pill-receivingcavities 24 andapertures 22. Conventionally blister packaging will include a plurality of cavities for storing medicaments and the present invention is not limited to a particular number of cavities. The present invention can accommodate any number of medicaments by including multiple rows or columns of cavities in the blister packaging. In reference toFIGS. 4 and 5 , theaperture 22 is slightly wider than the width of ablister 19 containing a pill-receivingcavity 24 and preferably has an arcuate shape as shown inFIG. 5 to guide theblister 19 that houses the pill-receivingcavity 24 along an arcuate path when a thumb or finger of a user is pressed against thelip 26 in the direction of thearrow 21 shown inFIG. 5 . Theblister 19 containing the pill-receivingcavity 24 will remain at afirst end 25 of theaperture 22, demonstrated with phantom lines, and will move to asecond end 28 of theaperture 22 when a user applies a sufficient force to thelip 26, in the direction of thearrow 21. Thebacking card 18 has at least one scoredexit port 40 hingedly connected at 41 to thebacking card 18 that is in registry with theblister 19 when it is in the full line position for the blister shown inFIG. 5 . The scoredexit port 40 is thus only in registry with theblister 19 containing the pill-receivingcavity 24 when a user moves the pill-receivingcavity 24 to thesecond end 28 of theaperture 22, as shown inFIG. 5 . - Referring now to
FIGS. 3 and 6 , acarrier tab 29, adeformation neck 30, and adeformation gap 34 are shaped into theblister laminate 14 by punching the shapes using a typical process, such as die-cutting. The blister laminate is punched prior to inserting theblister laminate 14 between thecover sheet 12 and thebacking card 18. The area of thecarrier tab 29 can be of any shape, but preferably the area is generally square and theblister 19 containing the pill-receivingcavity 24 is located approximately in the center of thecarrier tab 29. Thecarrier tab 29 is integrally connected to adeformation neck 30. While in an initial position, demonstrated byphantom lines 35 inFIG. 6 , thecarrier tab 29 is held in place by a connection means 32. The connection means 32 should be selected such that theblister 19 containing the pill-receivingcavity 24 will resist moving until a user applies a sufficient amount of force to thelip 26 to break the connection means 32 thereby disengaging thecarrier tab 29 from the rest of theblister laminate 14. The preferred connection means 32 is a single short, thin strip of theblister laminate 14 alongedge 33 that is not cut during the punching process. Applying enough force to thelip 26 to tear the short,thin strip 32 of blister laminate should be difficult to accomplish for a young child, but easy for an adult. The resistance generated by the connection means 32 can be easily modified to be more or less difficult by varying the number or type of connections means. For example, multiple short, thin strips of blister laminate along theedge 33 can be formed during the punching process or a combination of a short, thin strip of blister laminate with a weak adhesive can be applied alongedge 33. Upon tearing the connection means 32, a user must slide theblister 19 containing the pill-receivingcavity 24 across thedeformation gap 34 which stops when thecorner 38 of thecarrier tab 29 engages aridge 36. Thegap 34 in theblister laminate 14 is formed such that its periphery runs at an angle as shown at 37 inFIG. 6 . An optionalelevated rib 39 runs parallel and adjacent to theridge 36 further facilitating the stop when thecorner 38 engages theridge 36. Referring toFIG. 5 , theend 28 of theaperture 22 also serves as a stop when theblister 19 containing the pill-receivingcavity 24 is pressed against theend 28 of theaperture 22. When slidingblister 19 containing the pill-receivingcavity 24, thedeformation neck 30 is bent and stressed as indicated bystress lines 31; however, thedeformation neck 30 is resilient, providing a spring-like resistance to movement of the blister in the longitudinal direction ofarrow 21. The resilience in thedeformation neck 30 provides an additional child resistant feature of the present invention. In order to align pill-receivingcavity 24 in registry with the scoredexit port 40, a substantially constant force must be applied to thelip 26 to keep theblister 19 containing the pill-receivingcavity 24 in the full line position therefore shown inFIG. 6 . - Referring to
FIG. 7 , once theblister 19 containing the pill-receivingcavity 24 is in the final position as shown in full lines inFIG. 6 , a user can remove a medicament stored in the pill-receivingcavity 24 upon engaging theblister 19 with a thumb or finger and applying a force in thetransverse direction 42, forcing the medicament through therupturable layer 16 and out through the scoredexit port 40. - From the foregoing it is seen that the present invention provides a package construction requiring exercise of a predetermined opening procedure to effectively bar access to children, and which otherwise fully accomplishes its intended objects.
- While preferred embodiments of the invention have been disclosed and described in detail, it is to be understood that the invention is not so limited, but rather it is intended to include all embodiments which would be apparent to one skilled in the art and which come within the spirit and scope of the invention.
