BACKGROUND OF THE INVENTION1. Field of Invention
The invention relates generally to containers that can be used, for example, to house a plurality of flat, elongate articles such as blood glucose test strips or other diagnostic strips. More particularly, the invention relates to inserts within containers that provide improved organization and accessibility of, e.g., blood glucose test strips, especially for persons with swollen or otherwise debilitated fingers, e.g., diabetics.
2. Description of Related Art
Diabetes is a chronic condition in which a person has elevated blood glucose levels that result from defects in the body's ability to produce and/or use insulin. It is estimated that tens of millions of people in the United States alone suffer from diabetes and hundreds of millions of people around the world suffer from the disease. Unfortunately, the incidence of diabetes is increasing. Without treatment, diabetes can lead to severe complications such as heart disease, stroke, blindness, kidney failure, amputations, and death related to pneumonia and flu.
Management of diabetes is complex as the level of blood glucose entering the bloodstream is dynamic. To properly manage diabetes, patients must, among other things, carefully monitor their blood glucose levels. Daily diagnostic information, such as blood glucose, is typically obtained from a capillary blood sample with a lancing device. The blood sample is typically disposed onto a portion of a blood glucose test strip, which is then inserted into a port of a blood glucose meter for measurement. This type of monitoring is typically necessary before meals and helps to regulate proper insulin intake.
In addition to the potential diabetes-related complications listed above, diabetes can also affect one's skin and increase the risk of problems with one's extremities. Diabetes patients often experience debilitating musculoskeletal changes, including joint pain, stiffness, swelling, and nodules under the skin, particularly in the fingers.
Blood glucose test strips are typically stored and sold in small, tightly sealed, environmentally controlled containers in quantities of about 25 or 50 strips per container. Tight seals, e.g., moisture tight seals, are important to preserve the useful life of blood glucose test strips, which may be adversely affected by moisture and other elements present in the ambient environment. These containers must be large enough to ensure that the blood glucose test strips are not damaged and that the strips do not interfere with the sealing integrity of the storage container. Current blood glucose test strip containers are often problematic for diabetics who have swelling, stiffness and/or pain in their fingers. The strips may be difficult to remove, especially one at a time, with a diabetic's swollen fingers. A user may need to compensate for the difficulty in retrieving a strip by tilting the container or shaking and pouring out the contents, which may cause the blood glucose test strips to become damaged, contaminated or lost. The ends of the vertically-disposed strips are typically located well below the opening of the container, and can thus be difficult to access for a diabetic, especially one strip at a time.
Thus, there is a need for environmentally controlled (e.g., moisture tight) containers that provide easier access to flat elongate articles, such as blood glucose test strips, especially for people with swollen fingers, e.g., diabetics.
BRIEF SUMMARY OF THE INVENTIONAccordingly, in one aspect, a container assembly is provided for storing one or more arrays of flat elongate articles. The assembly includes a container body having a base, a sidewall extending vertically from the base, a dispensing opening and an interior space. The container assembly further includes a lid optionally linked to the container body by a hinge. The lid is configured to seat on the container body and cover the dispensing opening when the lid is closed. The assembly further includes an insert disposed within the interior space of the container body. The insert is adapted to hold at least one array of flat elongate articles in a generally vertical and optionally slightly slanted storage position. The insert includes a platform adapted to hold a first flat elongate article in an array higher than an adjacent second flat elongate article in the same array.
In another aspect, inserts for container assemblies are provided, which facilitate the organization and configuration of arrays of flat elongate articles. Inserts according to the present invention may hold such articles in a generally vertical (optionally, slightly slanted) storage position and facilitate accessibility of the articles for extraction, e.g., one at a time, especially for persons with debilitated fingers, e.g., diabetics.
The invention will be described in conjunction with the following drawings in which like reference numerals designate like elements and wherein:
In general, the present invention relates to containers and container inserts that store flat elongate articles, such as blood glucose test strips or other diagnostic strips, and facilitate easy access to such articles. As used herein, an “insert” may be a separate component that is inserted into a container, or alternatively, may be a structure that is integral with (e.g., molded as part of) the container. The preferred form of container according to the present invention is a vial, but other container types are contemplated. The term “article” as used herein refers to any flat elongate article, preferably a diagnostic test strip, more preferably a blood glucose test strip.
The various embodiments of the present invention as shown in the accompanying drawing figures each provide a solution to the problems presented by standard blood glucose test strip containers. Namely, the container assemblies described herein organize a plurality of strips in one or more arrays and position the strips such that they may be easily accessed and removed, e.g., one at a time, by a user.
Referring now in detail to the various figures of the drawings wherein like reference numerals refer to like parts, there are shown perspective views and sectional views of several container assemblies 10 according to the present invention. Each container assembly 10 includes a generally tubular container body 12 having a base 14, a sidewall 16 extending vertically from the base 14 and a dispensing opening 18, optionally opposite the base 14. The container body 12 includes an interior space 20 and optionally a desiccant material 22, e.g., a desiccant entrained polymer, communicating with the interior space 20. Each assembly 10 further includes a lid 24, which is preferably vaulted so as to provide clearance for the ends of, e.g., stored diagnostic test strips when the lid 24 is closed on the container body 12. In other words, the ends of the stored articles optionally protrude above the dispensing opening 18 when in storage position and into the optionally vaulted space in the underside of the lid 24 when the lid 24 is closed. The lid 24 is optionally linked to the body 12 by an integral hinge 26. The hinge 26 can be configured to orient the lid 24 to seat on the body 12 when the lid 24 and body 12 are together. As illustrated in several figures, the integral hinge 26 can extend from the sidewall 16 of the body 12.
The lid 24 and body 12 preferably include complementary sealing surfaces which, when the lid 24 is closed, provide a moisture tight seal. For example, sealing configurations that may be used according to the present invention include, but are not limited to: the lip-seal configuration disclosed in U.S. Pat. No. 7,537,137, which is incorporated herein by reference in its entirety; or sealing configurations disclosed in U.S. Pat. Pub. No. 2011/0127269, which is incorporated herein by reference in its entirety. Other moisture tight sealing configurations are contemplated as well.
As used herein, the terms “moisture tight” mean the moisture ingress of the container (after three days) was less than about 1500 micrograms of water, in another embodiment, about 500 micrograms of water, in a further embodiment, about 300 micrograms of water, in yet another embodiment, about 150 micrograms of water determined by the following test method: (a) place one gram plus or minus 0.25 grams of molecular sieve in the container and record the weight; (b) fully close the container; (c) place the closed container in an environmental chamber at conditions of 80% relative humidity and 72 F.; (c) after one day, weigh the container containing the molecular sieve; (d) after four days, weigh the container containing the molecular sieve; and (e) subtract the first day sample from the fourth day sample to calculate the moisture ingress of the container in units of micrograms of water.
The container assembly 10 is preferably resealable, i.e, the lid 24 can be opened/reopened and closed/reclosed numerous times (e.g. more than ten times) and the assembly 10 can still retain its moisture tight properties. Preferably, a moisture tight container assembly according to the present invention would admit less than 1,000 micrograms per day of water determined by a moisture ingress test method. The container optionally is sized as a pharmaceutical package (e.g., a vial) enclosing between 1 and 500 ml of interior volume, alternatively between 10 and 200 ml of interior volume, alternatively between 20 and 100 ml of interior volume.
The container assembly 10 further includes an insert 28 disposed within the interior space 20 of the container body 12. As described above, the insert 28 may be a separate component inserted within the interior space 20 or, alternatively, may be an integral part of (e.g., molded into) the container body 12. The insert 28 in any given embodiment retains a plurality of flat elongate articles 30 in a storage position (and in some instances, a separate retrieval position) that enables easy access to and removal of the articles, e.g., one at a time, by a user with debilitated fingers. The present invention includes optionally empty container assemblies as described herein, or optionally container assemblies as described herein containing a plurality of flat elongate articles (e.g., blood glucose test strips or other diagnostic strips).

The assembly 10 further includes a knob 63 disposed within a recess in the base 14 of the container body 12. The knob 63 is rigidly secured to a threaded shaft 65 which protrudes through a small opening optionally in the center of the base 14 and into the interior space 20 of the container body 12. Manual rotation of the knob 63 rotationally drives the shaft 65. The insert 28 includes a threaded tube 66. In assembled form, the shaft 65 threadedly engages the tube 66 of the insert 28. In use, rotation of the knob 63 drives the insert vertically, either upward or downward, depending on the direction of rotation. Preferably, a round seal 64, made e.g., from a thermo elastic polymer, is seated around the tube 66 above the base 14. The seal 64 protects the seal integrity of the container at the point where the shaft 65 enters the inner space 20 of the container body 12 through the base 14.
