This invention relates to a container for dispensing articles with features which promote compliance with established guidelines for dispensing particular articles. More specifically, the invention is a container for sequentially dispensing articles in accordance with compliance requirements. In one embodiment, the invention is a unit dose package for containing pharmaceuticals which promotes patient compliance with recommended dosage. The dispensing container further promotes safety with respect to child resistant packaging and ease of use with respect to senior patients.
A variety of pharmaceuticals are prescribed for consumption at a specified dosage per day. Compliance guidelines may require that a particular dosage of medication be consumed per day. For example, compliance guidelines may require that a patient consume medication over a one week period at increasing 10 milligram (mg) increments per day.
Known packaging incorporates written instructions describing the sequential dosage of medication (i.e., compliance guidelines). Other packaging may incorporate instructional tear strips describing compliance guidelines. This known packaging often fails to include clear dosage instructions, thereby increasing the likelihood of a patient ingesting an incorrect dosage which could lead to medical complications. Further, known packaging often fails to provide sufficient security features for child resistant packaging and fails to provide packaging readily opened by senior patients. Known dispensing containers are often too complicated to be readily accessed by seniors, or too flimsy to provide adequate child resistant features. Other known dispensing containers provide inadequate features for enforcing compliance with unit dosage requirements or, when provided, the features require time-consuming education provided by, for example, a pharmacist or doctor. The present invention provides a dispensing container having compliance and safety features which address these problems.
The invention is a container for dispensing articles having a bottom panel that defines at least one opening, a top panel that is secured to the bottom panel, and a moveable security member positioned between the bottom and top panels. In one embodiment, the dispensing container may include at least one perforated access tab defined by the top panel. The perforated access tab may extend along a portion of the width of the bottom panel. The perforated access tab is releasably secured to a portion of the bottom panel with, for example, an adhesive placed on the bottom panel or perforated access tab. The adhesive is positioned substantially adjacent to a portion of the security member. The adhesive forms an attachment point between the perforated access tab and bottom panel. The attachment point defines a stop that prevents movement of a shaped security member within the container and prevents the dispensing of articles from the container. Upon release of the perforated access tab, the security member is moveable (i.e., indexed to another stop formed by another adjacent perforated access tab) and articles within the container are dispensed through an opening formed by, in one embodiment, the removal of a portion of the perforated access tab.
In another embodiment, the top panel includes a perforated cut-out positioned substantially adjacent to the perforated access tab. Upon removal of the perforated access tab from the bottom panel, the security member is moveable. In this embodiment, the articles are dispensed through an opening formed by removal of the perforated cut-out as compared to an opening formed by removal of the perforated access tab.
Stated differently, upon release from the top panel the perforated access tab permits the security member to advance within the interior of the container. Movement of the security member facilitates communication between the interior of the container and an opening formed in the top panel by the perforated access tab or the perforated cut-out. Thus, movement or indexing of the security member permits the passage of an article from the interior of the container through an opening in the top panel.
Advantageously, the dispensing container may include multiple openings in the bottom panel, and multiple perforated access tabs and multiple perforated cut-outs in the top panel. Accordingly, the sequential release of the access tabs from the top panel and the advancement or indexing of the security member adjacent the openings promotes the dispensing of, for example, pharmaceuticals, in accordance with compliance requirements.
Access slots are provided in the top panel to facilitate removal of the access tabs. The access slots are formed substantially adjacent to the perforated access tabs and permits a user to insert a finger into the slot and remove a portion of the access tab prior to dispensing.
The invention may further provide a blister card or blister pack secured between the bottom panel and security member, wherein the blister card defines at least one cavity that contains, for example, pharmaceuticals. As configured, the cavity is correspondingly aligned with an opening in the bottom panel such that the opening receives that portion of the blister card defined by the cavity and containing the pharmaceutical.
In one embodiment, the perforated cut-out is correspondingly aligned with the opening in the bottom panel and the cavity defined by the blister card. In this embodiment, the perforated cut-out provides an opening through which articles are dispensed. More specifically, a user may remove a portion of one or more perforated access tabs, advance the security member beyond one opening in the bottom panel, apply a force against the cavity, and dispense a dosage through an opening in the top panel formed by the perforated cut-out. In the embodiment lacking the perforated cut-out, the dosage is dispensed through an opening formed by removal of at least a portion of the perforated access tab.
The invention may also provide at least one cover panel that is flexibly connected to the bottom or top panel by at least one side panel. The cover panel is foldable over the bottom and top panel for shipment and storage. In this embodiment, the cover panel provides additional protection for the articles within the container and additional surface area for indicia such as trademarks, instructions, or the like. It will be understood that other embodiments of the invention may provide two cover panels connected to the bottom and top panels, respectively, opposite one another.
The bottom and top panels further define a tear flap at one end of the dispensing container. The tear flap is formed by perforations extending along free edges of the bottom and top panels. In use, removal of the tear flap permits access to an end of the security member such that a user may pull the security member to advance it within the container. A portion of the perforations defining the tear flap may extend inwardly from an edge of the bottom and top panels to form a recess or indent in the panels. The indent permits ready access to an end of the security member extending beyond the edge of the top and bottom panels upon removal of the tear flap.
The dispensing container can be formed from cardboard, rigid paper, flexible plastic, or similar material made of paperboard or plastic, or any other material suitable for the purposes of the invention as set forth herein.
Thus, the invention provides, among other benefits, a container that facilitates the sequential dispensing of articles stored within the container in accordance with, for example, pharmaceutical compliance requirements. In particular, the combination of the moveable security member and perforated access tabs that provide sequential advancement of the security member promotes adherence to compliance requirements and ease of use lacking in known dispensing containers.
The foregoing and other objects and advantages of the invention and the manner in which the same are accomplished will become clearer based on the following detailed description taken in conjunction with the accompanying drawings in which:
The invention will now be described more fully hereinafter with reference to the accompanying drawings, in which multiple embodiments of the invention are shown. This invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout. Further, like numbers with the prime notation refer to like or similar elements of the structure.
As known to those skilled in the art, packaging is typically formed from packaging blanks, or blanks for short. It will be understood that as used herein the term “blank” may include cardboard, rigid paper, flexible plastic, or similar products made of paperboard or plastic. In particular, the packaging industry favors the use of one-piece flexible blanks, which are readily incorporated into automated processes for forming containers. It will be understood by those skilled in the art that the term “container” as used herein refer to various embodiments of the present structure for retaining a variety articles as formed from the various embodiments of the blank described below.
As used herein, the term “panel” is used in conjunction with the dispensing container of the present invention and refers to the major component part of a folding container and defines the major partition elements of the blank or container. It will be understood that panels include edges defined as the line of intersection of two surfaces or a border. A “free edge” of a panel refers to an edge that does not intersect with another surface or panel.
The term “flap” refers to a secondary container element that is typically hinge-connected along a free edge of a panel or another flap. It will be understood that the term “tab” refers to a tertiary element of the blank or container that is generally hinged to a portion of a free edge of a panel or flap, or struck from within the plane of a panel or flap.
It will be understood that the terms “top panel” and “lower panel” may also refer to “lower panel” and “upper panel” dependent upon the perspective of the individual viewing the apparatus. It will also be appreciated that the term “top” implies the opposite of “bottom.”
With reference to the orientation of the container in
It will be further understood that the dimensions, or measurements for containers will be typically be expressed in the order of length (L), width (W), and depth (D), wherein L is typically the larger dimension at an open end of the container, W is usually the smaller dimension at an open end of the container, and D is the distance between the open ends of the container (e.g., L×W×D). With reference to the orientation of the top and bottom panels in
Further, it will also be understood that as used herein, the concept of a panel being “between” two other panels does not necessarily imply that the three panels or flaps are contiguous (i.e., in intimate contact). Rather, as used herein, the concept of one panel being between two other panels is meant to describe the relative positions of the panels within the blank structure, respectively.
Similarly, the concept of a first panel being connected to a second panel by a third panel, “opposite” the second panel, merely describes the relative positions of the first and second panels within the blank structure. It will further be understood that the term “finished” means coated with a material to produce an attractive glossy finish. The term “finished” will also be understood to mean the inclusion of printed material or other identifying indicia (e.g., a company's logo).
It will be understood that the term “score” refers to a crease along which the adjacent elements of the blank are folded without cracking or breaking to form a sleeve or container. It will be understood by those skilled in the art that the term “cut-score” refers to an impression formed by a cutting tool (e.g., a punch, die, or blade) that extends partially through a sheet of paperboard or the like. It will be understood that the term “perforations” refers to a series of holes or impressions formed by a cutting tool (e.g., a punch or die) that permits easy separation of, for example, panels. The term “perforated cut-out” refers to an impression formed in the blank that, upon removal, forms an opening.
It will be further understood that the term “fold line” or “score line” refers to a crease along which the adjacent elements of a blank are folded without cracking or breaking to form a container. It will also be appreciated that the term “glue release section” refers to a portion of, for example, a first panel to which an adhesive is applied such that a second panel can be secured against the panel having the glue release section and bearing the adhesive. The term “secured” may refer to adhered with adhesive (e.g., glue) or bonded with heat.
It will also be understood that the term “substantially rectangular” is meant to succinctly describe a simple geometric shape approximating a rectangle. Similarly, the term “substantially parallel” is meant to describe the spatial relationship between, for example, one panel to another panel, wherein the relationship is approximately parallel.
It will also be appreciated that the term “adjacent” refers to two or more, for example, panels that have a common border or are in close proximity to one another. Nevertheless, it will be understood that adjacent may or may not imply contact, but always implies the absence of anything of the same kind in between. Furthermore, as used herein, it will be understood that the term “article” will refer primarily to consumer products that are packaged for shipment (e.g., pharmaceuticals, consumables, etc.). It will be understood, however, that “article” may also refer to any number of goods such as individually packaged consumables for humans and animals, as well as individually packaged non-consumables. “Flexography” refers to a process of rotary letterpress printing using flexible plates and fast drying inks.

In one embodiment, the method provides for the in-line processing of blanks used to form pharmaceutical packaging. In particular, one or more sides of the web (or substrate) is coated with a blister coating, instructions or graphics (i.e., indicia) are printed via flexography on one or more sides of the web, and the web is die-cut to form blanks capable of forming pharmaceutical packaging. In one embodiment, the method is accomplished by advancing the web along a transport path to a series of work stations. Advantageously, the present method is an in-line process incorporating the coating, printing, and die-cutting steps that typically are accomplished off-line and oftentimes at geographically separate locations. Thus, the inventive method reduces production costs and production time.
Known methods of manufacturing pharmaceutical packaging require a manufacture to purchase sheets of paper—as opposed to rolls of paper—from a supplier that have been pre-coated with, for example, blister coating of the type used in pharmaceutical packaging. These pre-coated sheets of paper are more expensive than rolls of paper lacking the blister coating. The supplier produces these pre-coated sheets by applying various layers of coating to a web and then separating the web into sheets according to the manufacturer's requests. The suppliers of the pre-coated sheets require relatively long lead times to produce the pre-coated sheets according to the manufacturer's specification. Upon production, the pre-coated sheets must be transported and delivered to the manufacturer. The long lead times from ordering to delivery make it difficult for the manufacture to efficiently order and stock the pre-coated sheets.
Further aggravating efficiencies, the pre-coated sheets have a limited shelf time (i.e., approximately six months). Thus, prior to ordering from the supplier, a manufacture must estimate its requirement for current and future orders of the pre-coated sheets. Estimated requirements often lead to overstock or lack of stock. A failure to use all pre-coated sheet stock on hand results in waste if the shelf-life has expired and the manufacturer is forced to dispose of the pre-coated sheet stock.
Moreover, known methods typically accomplish the steps of coating, printing, and die-cutting at geographically separate locations. Stated differently, known methods do not provide an in-line continuous process for the coating, printing, and die-cutting of pharmaceutical packaging at one geographic location. The present method addresses inefficiencies in the known methods.
The step of providing a web may include providing a roll of paper or paperboard material having a first and second side. Upon the step of providing, the web is advanced to a first coating station where a first layer of coating is applied to the first side of the web. This first layer of coating serves as a primer. This coating may be any number of types of waterborne polyurethane blister board coating designed for in-line coating over wet ink or off-line coating over dry ink.
Next, a second layer of the coating is applied to the first side of the web over the first layer of coating. The combination of the two layers of coating serves as a heat seal or blister coating.
As a next step, the web advances to a verification station where the web is inspected to ensure that the amount of blister coating applied to the web exceeds a predetermined standard. In one embodiment, the inspection step determines whether the coated web is of a desirable minimum weight to ensure that a sufficient amount of coating (formed of the first and second layers) is present to form a proper bond between the coating and web when heat and pressure are applied at the final operation of packaging, for example, pharmaceuticals or pills. It will be understood that webs of this type are measured in pounds per thousand square feet.
It will be understood that the method of inspecting may include a weight measurement of the coated web, a thickness measurement of the coating on the web, or any number of methods for ensuring that the amount of coating present on the web is sufficient to meet a desirable standard for proper sealing performance on a pharmaceutical (or pill) packaging line. A proper seal on the pharmaceutical packaging line is necessary to ensure that a pharmaceutical package design meets its functional requirement to prevent children from obtaining ready access to an article (e.g., pharmaceutical) in the container, while permitting access to an article by a senior patient.
During the inspection, at least a portion of the width of the coated web is inspected using, for example, a scale, a scanner capable of measuring the thickness of the coatings and/or web, or any number of devices capable of measuring the weight of the coating or the thickness of the layer of coatings and/or web. It will be understood that the goal of the inspection is to ensure that a sufficient amount of coating has been applied to the web to ensure a secure heat seal.
Upon satisfying a desired measurement, the web advances to the next station. Alternatively, an indicator will inform the user that the web does not meet a desirable measurement. When sub-standard portions of the web are identified, advancement of the web may be stopped and the sub-standard portions are removed before advancement to a die-cutting operation.
The web coated on one side is then advanced to a turning station where the web is turned or flipped over by a turning arm. The turned web is then advanced to a printing station where indicia in the form of printed instructions or graphics are applied to the second side of the web opposite the first side bearing the first and second layers of coating.
In an optional step, the web is advanced to another coating station where a first layer of coating is applied to the second side of the web containing the indicia (i.e., opposite the side of the web having the first and second layers of coating). This first layer of coating is applied to the second side of the web as a protective layer over the indicia. This first layer of coating on the second side may include any number of aqueous-based or ultraviolet (UV) coatings.
In the final steps of the method, the web is advanced along the transport path to a separating station where the web is die-cut into any number of blanks. Upon die-cutting the web into blanks, the blanks are ready for transport to a pharmaceutical manufacturer for construction of the packaging or container. In one example, the blanks are transported to a pharmaceutical manufacture where two blanks are formed into a single container and a blister card containing pharmaceuticals is incorporated therein.
This novel method further provides for the manufacture of small dimension packaging requiring blanks smaller than 20″×26″ in small to medium run sizes generally ranging from 1000 to 1,000,000 blanks. The present method also increases storage efficiencies by permitting the manufacturer to produce a die-cut blank of specific dimensions directly from a web as opposed to storing large quantities of pre-coated sheets having limited shelf life. It will be understood that this method provides for packaging used in healthcare, pharmaceuticals, cosmetics, consumer goods (e.g., small boxes) and promotional cartons.
