BACKGROUND OF THE INVENTION

Child-resistant caps are used to prevent young children from accessing the contents of a bottle or a container and consuming them inadvertently. The general objective of the child-resistant closure mechanism is the use of multiple steps to remove the cap from the bottle or the container which would not be obvious to and difficult for young children intuitively figure out. One of the challenges with child-resistant caps is that elderly and frail people may also encounter difficulty in removing the child-resistant cap from the bottle or the container due to a number of factors, including weakness and reduced manual dexterity due to musculoskeletal diseases, such as arthritis.

One of the commonly used child-resistant closure mechanisms is the push-down-and-turn the cap to remove the cap from the container system. The current design of the detent on the locking notch with the closure system is angular resulting in “stickiness” when the lug from the cap is disengaged from the locking notch on the container system, which can cause difficulty and even pain in the process for some people. The present invention relates to two new and one improved child-resistant closure mechanism using tapered detent on the locking notch to reduce the “stickiness” when removing the cap from the container system.

In addition, the present invention relates to new and improved prescription pill bottles and caps. Currently, prescription medications, such as tablets and capsules, are dispensed by pharmacies in circular, cylindrically-shaped prescription medication vials, with the prescription and auxiliary labels affixed wrapped around the barrel of the vial and some of the caps used are also circular cylindrical in shape and have a narrow grip area. There are a number of disadvantages with these vials and caps, which the present invention aims to address.

The first disadvantage of the vials are that they are not ergonomic. In order to grip the vials, there is a considerable bending of the fingers. This action can be difficult and even painful for people with reduced manual dexterity due to musculoskeletal diseases, such as arthritis. Secondly, in order to read the instructions on the labels affixed on them, one has to rotate the vials back-and-forth, which is not ideal for reading the instructions on the labels especially if the instruction in not straightforward. As for the caps, Some of the caps have a combination of a narrow grip area and knurling, which can make removing the cap difficult and even painful, again especially for those with reduced manual dexterity, such as arthritis.

The aging population is increasing and generally, the incidences of musculoskeletal diseases increase with age, as well as other medical conditions, such as high blood pressure, diabetes, high cholesterol, etc. As a result, the number of people requiring prescription medications, as well as the number of medications taken by each person will increase with time. For a number of people, the use of prescription medications already are an integral part of their lives and will become for many more with time. Therefore, it is important to have pharmacy pill bottles and child-resistant caps that are ergonomic and easy to use, and bottles that offer a relatively easy reading platform for the labels. The present invention aims to have a positive impact on the lives of many people who have to take prescription medications daily by offering ergonomic bottles and caps, and ergonomic bottles with a relatively planar surfaces for labels.

BRIEF SUMMARY OF THE INVENTION

Embodiments of the present invention is a novel child-resistant closure mechanism comprising of a plurality of J-shaped grooves located circumferentially spaced around the outward side of the neck of the bottle or a container system where the longer vertical groove opens at the rim of the neck. To cover the mouth opening of the bottle or a container system with a cap, the grooves engage with the locking lugs located circumferentially spaced on the inner surface of the cap projecting inwardly spaced and configured to fit the grooves. Once the lugs engage with the grooves that open at the rim of the neck, the cap is pushed axially along the longer grooves. When the lugs reach the curving part of the J-grooves, the cap is rotated clockwise which causes the lugs to glide along the curvature of the J-grooves. After the lugs pass the curvature of the J-shaped groove, the resilient member located inside the top part of the cap causes the lugs to push up into the short vertical grooves where the lugs rest in a locked position. The cap is now in a locked position. The cap is removed from the neck by pressing the cap axially against the neck which releases the lugs from the shorter vertical grooves, then by turning the cap counter clockwise causing the lugs to glide along the curved grooves, and then by pulling the cap axially along the longer vertical grooves and then off the neck. The grooves, in the shape of the capital letter J, on the neck offer a novel child-resistant closure mechanism and are easy to use.

Another embodiments of the present invention is a plurality of a variation of the J-shaped groove located circumferentially spaced around the outward side of the neck where the opening of the groove at the rim of the neck is wide to allow easier engagement of the locking lug on the cap with the groove on the neck. The wide groove entrance funnels into a narrower, vertical groove guiding the lug into a locking position thereafter in the same manner as with aforementioned J-shaped groove.

Another embodiments of the present invention is an improvement in the design of the existing push-down-and-turn child-resistant closure mechanism comprising tapered camming latch leading to an angular detent that is part of the notch on the neck of the bottle or a container system which receives the locking lug from the cap to close the mouth opening on the bottle or a container system. The detent causes stiff, “sticky” release of the locking lug when the lug is disengaged from the notch. The stiffness can make the cap difficult to remove and even be painful for people with musculoskeletal disorder, such as arthritis. The stiffness can be reduced by tapering the detent. The present invention relates to a camming latch leading to a tapered detent part of the notch for smoother transition of the lug. It is understood the neck may have a plurality of camming latch with a tapered detent/notch.

Another embodiments of the present invention is a cap that is comprised of a top panel and an annular skirt, which depends downwardly from the outward periphery of the top panel forming the cap body. A resilient member is fitted inside the upper end of the cap body. On the inner surface of the cap body is a plurality of locking lugs projecting inwardly. The lugs engage with the grooves on the neck of the bottle or the container system in one closure mechanism and with the camming latches and are received into the locking notches on the neck of the bottle or the container system in another closure mechanism to close the mouth opening of the bottle or the container system. The resilient member located inside the upper end of the cap body permits the cap to be pressed axially against the neck and release the lugs from the locked position and allow the cap to be removed from the neck. The cap body may have the upper end wider than the lower end, thus having the appearance of an upside down, truncated circular cone and offers a relatively wide grip area. Alternatively, the cap body may have the traditional circular cylindrical shape.

Another embodiments of the present invention are a plurality of generally elliptical cylindrically-shaped pharmacy pill bottle. The front and the back of the bottle are slightly curved, which are connected by curved side portions forming the generally elliptically shaped bottle. At the top-center of the bottle is a wide, circular cylindrically-shaped neck connected via the shoulder and at the upper end of the neck is a mouth that opens into the chamber of the bottle.

The intended use of the present invention is for dispensing prescription medications, such as tablets and capsules, by pharmacies. The present invention of child-resistant cap may be applied to a bottle and other container system. The present invention of child-resistant cap is easier to operate than the comparable push-down-and-turn caps. The present invention of prescription pill bottle offers ergonomic grip compared to the traditional prescription pill vial thereby reducing hand-fatigue and thus improving the quality of life of those who have to use the prescription pill vials daily. In addition, the present invention of prescription pill bottle offers a relatively planar surfaces on the front and the back for prescription and auxiliary labels to be affixed allowing following the instructions on the labels easier.
