Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a reusable and lockable unit dose packaging system comprising a paperboard portion and a molded locking member. This package is suitable for packaging medications because it is easy to use and has child resistance. It can also withstand repeated use, including opening and closing the locking mechanism.
[0002]
[Prior art]
The concept of unit dose packaging is attractive for pharmaceutical applications. This is because individual quantities can be easily and systematically distributed, and the user can track consumption of quantities according to an instructed schedule. A characteristic of such packaging is that it is robust enough to open and close many times until treatment is complete. An example of such packaging is disclosed in US Pat. No. 6,047,829 (Johnstone), also assigned to the present applicant. The Johnston patent relates to a unit-size paperboard package having an outer paperboard sleeve and an inner paperboard slide card that is lockably held inside the sleeve. The sleeve has a plurality of side panels operatively connected to each other, one of the plurality of side panels having a first inner slide card release means, the other of the side panels being a first one. Two inner slide card releasing means, and the inner slide card holding means and the releasing means are arranged so as to be substantially adjacent to the unit quantity distributing means.
[0003]
Child safety is a particularly desirable feature for unit dose drug packaging, and is defined by the 1970 Poison Prevention Packaging Act. Under this law, guidelines for packaging that meet child safety standards are established. For example, a child safety (CR) rate of F = 1 requires that random sampling of test packages does not drop to a failure rate of 10% or more with a test pool of children of a particular age. This general guideline is designed to maintain sufficient integrity for children to play with the package.
[0004]
[Problems to be solved by the invention]
An object of the present invention is to provide an enhanced unit dosage package having a particularly durable locking structure. Another object of the present invention is to provide a unit dose packaging system that can be easily opened while meeting and maintaining the desired child safety standards throughout its service life. These and other objectives are met by various embodiments of the present invention, including improving aesthetics and improving transport and packaging stability.
[0005]
[Means for Solving the Problems]
The unit dose packaging system of the present invention consists of a combination of members that form a rugged, child-safe package. In this regard, the package member has a flexible portion consisting of a series of continuous panels and a rigid molded plastic locking member. The unit quantity is accommodated in a structure inside the package, such as a card, dispenser, or other structural member.
[0006]
The flexible portion is formed from paperboard or a flexible, foldable plastic material, but it is preferred to use paperboard. This portion of the package preferably cooperates with the molded locking member to form a rigid frame surrounded by an outer cover. In this regard, one or more panels of the paperboard portion are at least partially attached to the molded locking member to form a rigid frame, and other paperboard panels are on the top and bottom of the frame. Expands to form an outer cover. These panels are cut to fit inside the frame provided by the plastic part, and one or more notches, notches, tabs, slots, etc. to securely attach the paperboard part to the plastic part. It has something similar to it. In this regard, for example, the paperboard panel forming the top of the package has a slot for passing a locking mechanism formed in the plastic part. The paperboard panel that forms the bottom of the package has notches, cutouts, tabs, etc. Sinking Means are also provided so that the members of the locking mechanism inside the package can be operated.
[0007]
The paperboard portion is formed from bleached, unbleached, uncoated, or coated C1S or C2S paperboard suitable for use in packaging. Also, if desired, the paperboard is laminated with a polymer material or other material to provide additional firmness and tear resistance. Such laminate materials are disclosed in co-pending US patent application Ser. No. 09 / 951,035, assigned to the same assignee as the present application, the disclosure of which is hereby incorporated by reference. Alternatively, the paperboard portion can be replaced by other foldable substrates such as plastic. It may also be formed from a single piece of substrate and folded to form each panel of the package, or alternatively, individual panels are cut from the substrate material to form the package. In order to do this, you may attach to the member for a lock as needed.
[0008]
The molded locking member has a locking member and a lock releasing member as basic members. Several embodiments of suitable locking members are disclosed in detail in co-pending US Provisional Patent Application No. 60 / 305,851, but are not limited thereto. At least one inventor of this application is in common with the present application, the entirety of which is hereby incorporated by reference. In such an embodiment, the molded locking member of the package includes the rigid molded portion of the frame described above, and the locking member is molded into a frame, a sliding locking tongue, and a locking flap. Is forming.
[0009]
The frame portion of the locking member comprises a panel that is connected at a right angle to form a polygonal package frame, and a frame base. The frame base is partially cut to accommodate a sliding locking tongue member. In addition to accommodating a sliding locking tongue, the frame base provides additional support and rigidity to the package. However, the frame base need not be formed as an uncut continuous panel. Instead, molding it to provide only the frame member reduces the package weight and material costs while at the same time providing the necessary support for the more flexible member of the package. It may be. The frame base is attached to at least one panel of paperboard parts by adhesive, mechanical means or other means. In one embodiment, the molded polygonal frame is rectangular, in which case it has two end panels that are lower in height and shorter than the remaining two side panels. Yes. One of the lower and shorter panels is located at one end of the frame to provide support and attachment points for the locking flap and the other at the other end of the frame opposite the locking flap It is preferable that they are arranged. The two side panels that complete the rectangular frame are attached by molding at right angles to the end panels. Each end of the side panel extends slightly beyond the attachment location to the corresponding end panel, and each end of the side panel forms a ledge to support the end panel overlaid with the paperboard portion. In order to further support this structure, a side panel or an end panel may be further provided on the frame.
[0010]
In addition to the end panel and the side panel, a slot housing panel is sandwiched between the side panels above the frame base. The panel has a slot for receiving and engaging a tab depending from the locking flap, sufficient to lift it above the frame base and engage the locking tongue below it. Molded to a proper thickness. The height of the slot housing panel is such that it supports the locking flap when the package is closed.
[0011]
A sliding lock tongue is accommodated inside the frame base. The locking tongue cooperates with the locking flap and the slot housing panel to close and secure the package. One end of the locking tongue is a pull ring. The other end of the locking tongue is integrally connected to the curved dwell. The curved dwell has an upwardly protruding edge. From there extends the outermost lateral tab of the curved dowel. This side tab engages the depending tab portion of the locking panel when it is inserted into the slot housing panel. The curved dwell is preferably held in position by a pair of stops molded into the slot housing panel. In the molded state, the curved dowels and tabs are housed under the slot housing panel. The sliding locking tongue can be molded as a single unit from a bendable plastic material. However, curved dowels that function to drive the movement of the bar when manipulating the pull ring are made of a more flexible plastic than the materials used to form the frame and other members of the locking member. It is preferable.
[0012]
A trigger mechanism is used to release the lock mechanism that is locked when the molded tension is not applied. In this regard, the trigger mechanism may be a pull ring or a lever or rod, such as a T-shaped lever. In one embodiment, the trigger mechanism is a circular pull ring. As the ring is pulled, the tongue moves and pulls the curved dowel and lateral tab from the underside of the slot housing panel. The locking tongue movement in the pulling direction is a pair of stops located in the frame base at a distance from the pull ring and horizontally arranged across the bar to engage these stops. Intentionally limited by stop ledge. The stop ledge extends across the bar and beyond its width, maintaining the bar and pull ring in the same plane as the frame base.
[0013]
The locking flap is connected to one end panel of the molded package frame by a hinge mechanism. This mechanism is preferably in the form of a living hinge that is molded with the locking flap. In some cases, the locking flap may have a finger grip for easy access by the user. A depending tab is attached to one end of the locking flap, preferably in the central portion thereof. The hanging tab has a slot corresponding to the side tab attached to the locking tongue. The locking mechanism is secured when the sagging tab engages the slot housing panel and the side tab engages the slot inside the sagging tab.
[0014]
The paperboard portion of the package is attached to the molded plastic portion by any suitable means. When the package of the present invention is used to hold a unit dose material such as a medicine, a medicine, or a nutritional supplement, a member for storing the unit dose is provided inside the package. These types of containers can be used to package other commodities and a wide range of materials when disjoint quantities are dispensed. Such members can be selected from blisters, pouches, pillows, foil inserts, and other receiving vessels, all formed by conventional means, and inserted as a paperboard part that forms the package or as a separate storage member within the container. Can be mounted on the card. For example, if it is desired to incorporate a blister card into a package, the blister card is formed as one or more extensions of a paperboard panel that forms the top, bottom and sides of the package.
[0015]
Part of child safety is achieved by exercising the firm locking function described here. To close the package, the paperboard portion is extended over the frame base and pressure is applied to the portion of the locking flap depending on the tab, causing the tab to engage a slot provided in the slot housing panel. As the sagging tab engages in the slot, it slides past the protruding side tab and snap-fits into place. In the fully locked state, the lateral tab exerts a force on the side of the sagging tab. Therefore, it is difficult to remove the sagging tab unless a moderate amount of pressure is applied to remove the lateral tab. The completely locked state is a state in which the locking member is molded.
[0016]
A more clever way is needed to open the package. The side tabs must be removed in order to pull the hanging tabs from the slot housing panel. In this regard, the user's finger is hooked to the pull ring at the bottom of the package and the ring is pulled in the direction opposite to the locking flap. The ring pulls the locking tongue, this time pulling the curved dwell out of the slot housing panel. There is no firm contact between the side tabs and the sagging tabs, and the sagging tabs are freely removed from the slot housing panel. The locking flap is then rotated around the integral hinge to release the package cover or top panel. In various embodiments, the pull ring is hidden from view outside the package by a bottom paperboard panel. In this structure, the paperboard panel is provided with a slot so that the pull ring can be operated. In other embodiments, a cutout is provided in the bottom side panel that allows free access to the pull ring. Once the locking flap is released, the quantity can be taken out by expanding the unit quantity accommodating part such as a blister card.
[0017]
As an additional defense when opening, the locking flap is partly divided into three segments by a pair of slits provided near the innermost edge of the locking flap. Each segment formed in this way can restrict movement relative to adjacent segments to some extent. To open the package, on the other hand, the locking tongue must be pulled out of the package by pulling out the locking tongue while pulling out the locking tongue from the slot housing panel.
[0018]
The invention further includes a method of packaging the unit dose material. This method
a) forming a locking member having a lock member and a lock release member from a rigid plastic material and a flexible plastic material;
b) cutting a blank from flexible paperboard or plastic material;
c) folding the blank and attaching it to the locking member;
d) inserting one or more doses of unit dose material into the container;

DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, the combined paperboard / plastic unit dosage package according to the present invention in one embodiment has a paperboard portion 2. The paperboard portion 2 has an upper panel 3 and an extension 4, which accommodates a unit quantity blister 16 thereon. The upper panel 3 is connected to the end panel 5 in a foldable manner. The end panel 5 forms the back of the package in the completed state. The bottom panel 6 is attached to a molded locking member 12. In this embodiment, the panel 6 has a slot 11 cut to provide a movable region on a portion of the molded part. In another embodiment, the notch that exposes the plastic part member can be replaced with a slot 11. The paperboard part 2 is attached to the molded plastic part 12 by an adhesive or a hot melt adhesive. Other attachment means may be used. The plastic portion 12 has a locking flap 13, a locking tongue 14, and a frame base 15. The frame base 15 further includes an end panel 22 and a side panel 23, and a slot housing panel 18. The end panel 22 and the side panel 23 are connected at a right angle to form a rectangular frame that limits the shape of the package 1. The slot housing panel 18 has a slot 21 for engaging with the locking flap 13 and has a hollow area (not shown) below it, in which the curve of the locking tongue 14 is located. The shaped dwell portion 27 is fixed. Unlike this, it is not necessary to use a double panel. Instead, the blister packaging material can be attached directly to a single blank panel by sealing or other known means. In another embodiment illustrated in FIG. 8, the frame base 15 has a series of end panels at the end of the package 1 opposite the locking flap.
[0020]
As shown in FIG. 2, the paperboard portion 2 is preferably formed as an upper panel 3 and an extension panel 4. As shown, the top panel 3 and extension panel 4 are formed from a double panel of selected substrate material. This double panel provides additional physical support to the package. Alternatively, a unit quantity blister may be formed by sandwiching a blister packaging material such as a laminate or foil sheet between the double panels 4. In use, the extension 4 is opened outward from the upper panel 3. Therefore, characters or designs such as medication instructions are printed on both the inner and outer surfaces of the upper panel 3 and the extension 4. The panels 3 and 4 further have slots 9 and 10 that are positioned and dimensioned to match when the double panel is folded. Since the slot is formed in this way, the hanging tab 19 of the locking mechanism can be passed through the upper panel and the extension panel 4 when the package is closed. As described above, the blank may not use a double panel or may be provided in multiple parts, such as a two-piece blank.
[0021]
A drawing from the top of the package in the closed state is shown in FIG. When the package is completely closed, the upper panel 3 is folded to the inside of the package and folded to the lower side of the locking flap 13. The panel 3 is held in position by a ledge 28 disposed near the edge of the side panel 23. When the panel 3 is pushed downward, its edge is pushed downward and is firmly engaged by the ledge 28 to hold the position. The locking flap 13 is divided into three by a pair of slits 37. The slit 37 divides the locking flap 13 into segments, and movement of each segment is restricted with respect to an adjacent portion. In this embodiment, egg-shaped finger grips 34 and 36 are formed at each end of the flap 13. In other embodiments, the grip is curvilinear, angular, or provided with ribs. Dividing the flap 13 into segments improves safety. This is because in order to open the package, the user must move the locking tongue 14 from an untensioned state by pulling at least one segment while engaging the pull ring 17. Without engagement with the ring 17, when the user grips only one finger grip 34 without pulling the other finger grip 36 or flap edge 35, the grip area segment is moved slightly and added. Rather than being applied to the flap edge 35 as required to remove the locking flap 13 from the slot housing panel 18, the tension remains localized around the grip 34 and the package is not easily opened. A slot 20 provided in the central segment of the locking flap 13 is arranged directly above the depending tab 19. The tab 19 protrudes downward to the lower side of the flat surface of the locking flap 13 and engages with the locking tongue 14.
[0022]
As shown in FIG. 4, the lower surface or bottom of the package 1 is a paperboard panel 6 on the outer surface. The panel 6 is in contact with the bottom surface of the frame base 15 and is held in position by an adhesive means, by engaging with the ledge on the side panel 23 described above, or both. Panel 6 is designed to operate the lower trigger mechanism. Means of sinking Is provided. In the illustrated embodiment, a square notch is cut to form a node 11 in the panel 6 above the pull ring 17. When the node 11 which is not fixed is pushed down, the user can grasp the pull ring 17 from the outside of the package 1 and move it. In another embodiment shown in FIG. 5, the node 11 can be eliminated and a notch 41 can be formed to expose the pull ring 17 partially or completely. However, by making the pull ring invisible, it becomes difficult to see the means for opening, thereby increasing child safety.
[0023]
FIG. 6 is a cross-sectional view of the package in the closed state, showing the internal position of the blister 16 containing the unit dose relative to the locking mechanism. The dimensions of the package are such that the blister 16 is not squeezed by the locking mechanism such as the frame base 15, the stop 30, the stop ledge 31, and the pull ring 17, particularly protruding upward from the plane of the bottom panel 6. It is preferable to be accommodated.
[0024]
An open package with the panels 3, 4 removed to show the locking member is shown in FIG. The locking member includes a locking flap 13, a frame base 15, a pull ring 17 formed integrally with the locking tongue 14, and a slot housing panel 18. The size of the pull ring 17 is designed to accommodate a general user's finger, and is installed inside a notch 32 that is provided so as to be able to move the pull ring 17. The end of the locking tongue 14 is a curved dowel 27 made of a flexible material. The dwell 27 is fixed to the frame base 15 at the attachment point 33. Side tabs 25 are arranged on the central region side of the curved dowel 27. The tab 25 protrudes outward from the end of the locking tongue 14 in parallel with the frame base 15. The locking tongue 14 cooperates with a pair of stops 30 and stop ledges 31. The stop ledge 31 is engageable with the stop 30 and restricts the movement of the tongue 14 to prevent it from moving out of the plane of the frame base 15.
[0025]
The locking flap 13 has a hanging tab 19 installed at a right angle to the flap 13 and a slot 20 disposed above the tab 19. The flap 13 is further divided into segments by slits 37. The flap 13 is attached to the frame base by a living hinge 26 molded with the other members of the locking mechanism and is located on the closed position side. The depending tab 19 corresponds to a slot 21 disposed in the slot housing panel 18. The slot housing panel 18 is adjacent to and partially connected to the end panel 22 inside the package frame.
[0026]
FIG. 8 shows another embodiment of the molded frame of the package 1. Here, a large number of end panels 22 and 24 having substantially the same dimensions are arranged in parallel but spaced apart from each other at the end forming the back of the package. These multiple panels provide additional support to the package frame. FIG. 8 also shows a curved dwell 27 of the locking tongue 14. The locking tongue 14 is molded and has side tabs 25 as shown. The curved dowel 27 is fixed to the molded frame base 15 at the attachment point 33. The flexibility of the curved dwell makes the locking tongue 14 easy to move relative to the support 38 and the frame base 15. The flexible portion of the curved dowel 27 is formed as a section 42 with a ridge 40 formed thereon for reinforcement and a thin portion 43 that facilitates bending of the section 42 relative to the locking tongue 14.

The curved dowel 27 is housed in a slot housing panel 18 (not shown) with side tabs 25 projecting outward into the slots 35 of the depending tabs 19. The locking flap 13 is divided into three segments by the slit 37, and finger grips 34 and 36 are arranged on the two end segments, respectively. To open the locking flap, the user first hooks the pull ring 17 and pulls it outwardly from the locking flap in the opening 32 and generally locks the tongue until the stop ledge 31 engages the stop 30. Pull 14 out. By pulling out the locking tongue 14, the curved dowel 27 is pulled out of the slot housing panel 18.
[0028]
FIG. 10 shows in cross-section the engagement of the hanging tab 19 and more particularly the slot 38 formed therein with the side tab 25 of the curved dowel 27.
[0029]
FIG. 11 shows the pull ring 17 partially moved outwardly in the opening 32 to withdraw the locking tongue 14. The pull ring is moved by grasping the top and bottom of the package, inserting a finger and manipulating the pull ring 17. When the locking tongue 14 is withdrawn, the side tab 25 extending from its end is withdrawn from the slot 39 in the depending tab 19. The user pulls the hanging tab 19 out of the slot 20 while hooking the pull ring 17 and simultaneously pulling one or both finger grips 34, 36. If one of the finger grips 34, 36 or the central segment is pulled without lifting the other segment, sufficient tension will not be transmitted to the central segment of the locking flap 13 to release the sagging tab 19 and the package Does not open immediately. The ease of operating this mechanism can be changed by shortening or lengthening the slit 37.
[0030]
The combination package according to the present invention is generally used in a mechanical operation in which a pre-cut and pre-folded blank is vacuumed or heat-sealed to the bottom of the frame base 15 and the attachment points on the end panels 5, 22 and the side panel 23. It is formed. A ledge provided along the length of the panel 23 allows the paperboard portion to snap fit into the forming frame formed by these side panels and end panels. The material and unit quantity forming the blister are inserted before the paperboard part is attached to the plastic frame, but this step is preferably performed after the package parts are joined.
