This application claims the benefit of U.S. Provisional Application No. 61/249,492, filed Oct. 7, 2009, and incorporated herein by reference.
TECHNICAL FIELDThe present invention relates generally to containers for pharmaceuticals, and is particularly concerned with a sliding lid container of the type including a bottle with a cover mounted thereon, wherein the cover includes a lid for slidable movement between open and closed positions with respect to the bottle.
BACKGROUND OF THE INVENTIONVarious systems have been developed to automatically fill large quantities of prescription bottles for use primarily in mail order pharmacies. For example, U.S. Pat. No. 5,208,762 to Charhut describes an automated prescription bottle filling system. The system automatically fills, labels, caps, and sorts prescription bottles in accordance with prescription orders stored in a database.
There is a strong need for a system that allows nested bottles to be loaded onto a conveyor system for filling. The system of the present invention provides this and other advantages.
All too frequently, errors are made by pharmacists or their assistants in filling prescriptions. Some of these errors are caught by the patient who notices the difference in the medication compared to medication previously obtained for the same prescription. However, under certain circumstances, the patient may not notice the error. For example, the erroneous medication, e.g., a pill, and the correct pill may be similar in appearance, or the error may occur the first time that the prescription is being filled. In other instances, the patient may simply fail to notice the mistake because differences in the size and/or color of the pills are difficult to detect, particularly if the patient has less than perfect vision.
Errors in the filling of prescriptions can arise from a variety of circumstances. In many instances, the error can be attributed to the inattention of the pharmacist, particularly during times when there is a need to fill a large number of prescriptions. Also, the error can be occasioned by the lack of experience of the pharmacist with the particular prescription, or the general lack of experience of the pharmacist's assistant. Other errors can be caused by the similarity of unrelated pills in color and/or shape. Errors can also arise from name similarities, e.g., Feldene/Seldane, Lodine/Codeine, etc.
Errors by pharmacists will continue to occur. Those errors that are not caught by the patient at least deprive the patient of the benefit of the prescribed medication. At worst, the errors can result in death or serious injury.
In order to reduce the number of accidental poisonings resulting from young children having access to unsafe medicines, drugs and other potentially dangerous substances, considerable effort has been made toward developing child-proof safety packaging. To fulfill the criteria of a child-proof safety package, a container and cap or cover must be constructed in such a manner that the type of manipulation required to open the container to gain access to its contents is one that a young child is not capable of performing. The safety packages are often of the type wherein a cap must be pushed axially toward the container against a biasing force, and then rotated with respect to the container in order to remove the cap from the container.
Due to the large number of prescription drugs, elimination of pills with similar colors, shapes and/or names is mathematically impossible. In fact, the extent of the problem will increase over time as new drugs become available. Human error will also continue. Therefore, there is a pressing and increasing need for a means to detect erroneously filled prescriptions.
With conventional prescription containers, the contents of the container are difficult to see since the bottle, while usually transparent, is of a bronze or other color to protect the contents from deterioration caused by light. Additionally, the contents are at least partially hidden by the opaque container cap and the label covering most of the bottle side wall. Thus, the patient, as well as the pharmacist, is prevented from seeing the container contents.
Ready identification of the container contents is further restricted by the size of the pills and the fact that any identification on the pills, such as the drug name, is in a small font, and may be impressed into the pill during manufacture so that the name is the same color as the pill. If the pharmacist could easily see the pills in containers that have been filled by others, such as his or her assistants, and if the patient could easily see the contents at the time of purchase, many of the errors could be caught before the pills are ingested.
SUMMARY OF THE INVENTIONAn object of this invention is to provide a sliding lid pharmaceutical container of the type wherein a container has a cover mounted thereon, wherein the cover includes a lid for slidable movement between open and closed positions with respect to the container.
A more specific object is to provide a sliding lid pharmaceutical container wherein a sliding is mounted in a cover housing for slidable movement between open and closed positions, and wherein resilient locking means is provided on the cover housing and sliding lid. The resilient locking means may comprise resilient locking members engaging detent structures of the sliding lid.
Yet another object of the present invention is the provision of multiple stackable bottles, yielding space savings which are particularly useful within automated dispensing equipment.
In carrying out the foregoing, and other objects, an embodiment of a pharmaceutical container according to the present invention includes a bottle and cover, the bottle having a bottom wall and side walls. Each side wall has a top end and a bottom end, and the bottom end of each side wall is connected to the bottom wall. One or more of the side walls includes a cover locking receptacle proximate to the top end of the side wall. A ridge proximate to the bottom wall projects from an interior surface of at least one of the side walls. The cover has a sliding lid contained in a cover housing. The cover housing has a top wall, which includes an opening, and four cover side walls. A bottle locking lug projects from the exterior surface of at least one of the cover side walls. This bottle locking lug is adapted to engage the cover locking receptacle of the bottle.
Lid retainers and lid locking lugs project from interior surfaces of cover side walls of the cover housing. The lid retainers engage the sliding lid such that the sliding lid is slidably mounted in the cover housing. The sliding lid is adapted to slide between an open position and a closed position.
The sliding lid includes four side edges. The side edges include grooves adapted to engage the lid locking lugs of the cover housing. The grooves of the sliding lid and the lid locking lugs of the cover housing may constitute locking means, providing resistance when moving the sliding lid from an open position to a closed position, and from a closed position to an open position.
In some embodiments, resilient biasing means are engaged between the sliding lid and the cover housing so that the sliding lid can slide from its closed position upon axial movement of the sliding lid with respect to the cover housing against the biasing means. In one embodiment, the resilient biasing means includes a lug and detent structure defined on portions of the cover housing and sliding lid.
The present invention is also directed to an array of pharmaceutical containers, including a plurality of bottles which are stacked, or nested. When a first bottle is nested inside a second bottle in accordance with the present invention, the bottom wall of the first bottle contacts a top edge of a ridge projecting from an interior surface of at least one of the side walls of the second bottle. This ridge is proximate to the bottom wall. In this way, a first bottle is prevented from being nested so tightly into a second bottle that it becomes difficult to remove from the second bottle.
The present invention is also directed to improved bottles for prescription drugs, and in particular to improved prescription drug bottles incorporating means to aid the pharmacist and the patient in noting when an error has been made in the filling of the prescription.
The present invention is particularly directed to prescription containers of the kind used to hold prescription medicines sold in solid form, e.g., pills, tablets, caplets, suppositories, or capsules. These medications in solid form will be referred to herein, for convenience and brevity, as “pills.” Generally, these containers are comprised of a bottle into which the pills are placed through an opening, a cap or cover attachable over the opening and a label that is affixed to the bottle. It will be understood, however, that the concepts forming the basis of the present invention can also be applied to medications in non-solid forms, such as liquids, ointments, or gels, etc., and to other receptacle configurations.
In one embodiment of the present invention, the bottle is generally of a tapered rectangular shape, having a continuous side wall with continuous upper and lower edges, and a bottom wall or base extending across the lower edge of the side wall. The bottom wall is sized to be received within an opening of an adjacent bottle, allowing a plurality of bottles to be presented in nested stack form. The bottle is structured adjacent the top end, or upper edge, of the side wall to receive a correspondingly structured cover used to close the bottle opening formed by the top ends of the side walls. The side wall may be structured on its outer surface, its inner surface, or both, depending upon the particular cover design. Additionally, the side wall may include locking receptacles or locking projections on its interior surface adjacent the top end, forming part of a locking mechanism. Usually, the side walls and bottom are integrally molded from a plastic.
The cover is normally molded from plastic material and is designed to be secured over the bottle opening. The cover may be pressed onto the top of the bottle. The exterior of the cover may include locking lug(s) to join with locking receptacle(s) on the corresponding bottle.
When a prescription is to be filled, the pharmacist, or his or her assistant, selects a large container of pills corresponding to the medication to be prescribed, transfers the designated number of pills from the large container to a bottle, and caps the bottle with its matching cover. An instruction sheet may also be included on or in the bottle. The pharmacist or assistant then types information about the prescription onto a label, and attaches the label to the side wall of the bottle.
Labels are normally pre-printed with standard information common to all prescriptions filled at the particular pharmacy, including the name, address and telephone number of the pharmacy. Information unique to the prescription, such as the patient's name, doctor's name, the name of the prescribed medicine, instructions for use, number of refills, etc., are then typed onto the label at the time the prescription is filled.
The present invention is directed to modifications of conventional pharmaceutical containers and the related procedures for their preparation that may be used alone or in combination to significantly increase the likelihood that the pharmacist or the patient will detect an error in filling the prescription in question.
In accordance with the present invention, a completed label, in addition to the name of the drug and other general and specific information of the type normally found on a prescription label, may also include an image of the pill present in the labeled container. The patient, before taking a pill, only needs to compare the actual pill with the pill image on the label to determine if the pills match. If so, the patient can be confident that the name of the pill on the label is the same as the pill in the container.
Therefore, in this aspect of the invention, the complete container will be comprised of a bottle containing the given medication, a cover to close the bottle, and a label attached to the bottle, the label having printed thereon the name of the given medication and an image corresponding to the medication.
In accordance with the present invention, the bottle and/or cover can be molded with a number of recyclable and biodegradable resins including polypropylene, polystyrene or polyethylene. These resins can also be incorporated with a UV resin additive to offer light shielding protection for the pill contents. The initial base resin can be clear or tinted.
In one embodiment, the lid may be connected to the bottle via a living hinge. In another embodiment, the lid may be separate from the bottle. The lid components can be molded in a range of colors for consumer selection to denote respective family member usage. The lid may include a child-resistant “push down and slide open feature”.
A pharmaceutical container in accordance with the present invention may be offered in multiple standard sizes for alternate pill sizes and dosages.
A bottle in accordance with the present invention offers easy carton stacking, unlike traditional vials and caps which are shipped to pharmacies separated in large bulk bags. Therefore, the bottle design may allow drug stores to realize considerable shipping, storage and handling savings. The separate covers may be shipped in a separate portion of a master carton, which may be designed to offer a dispenser style magazine retention option for easy pharmacist storage and access.
Moreover, a tapered rectangular bottle in accordance with the present invention offers considerably more easy-to-read flat surface area for larger print labels, which provides a safety benefit to patients.
