This invention relates to a container. In particular, the invention relates to child resistant (“CR”) containers for small objects.
It is well known that the storage of various types of small objects must sometimes be accomplished in a manner that prevents children from obtaining and handling the objects. An obvious example of such small objects is pharmaceutical pills and capsules. Various government regulatory bodies throughout the world require pharmaceutical manufacturers to package their products in CR packages. An example of such a regulatory body is the U.S. Consumer Product Safety Commission, which has historically regulated CR packaging in the United States. Various other organizations provide design and manufacturing standards for compliant CR packaging. One example of such an organization is the American Society for Testing and Materials (“ASTM”), which has created the ASTM D3475 Standard Classification for Child-Resistant Packages.
In recent years, there has been increasing demand for CR ASTM certified packages for small objects that have a more modern or trendy design. Many companies and individuals have expressed a desire for pill bottles that do not look like traditional pill bottles. Such traditional pill bottles are viewed by some as being unattractive and requiring use and storage behind closed doors. At present, while there are over a hundred variations of pill bottles for packaging pharmaceutically driven products, each having CR ASTM certification, there are very few new and modern packages of this type available in ASTM's listings that are not obviously pill bottles. Accordingly, there is a need for a modern, attractively designed container suitable for pills or other small objects.
Further, some have believed there are no acceptable options for new CR ASTM package designs. Many traditional pill bottle designs have been in use for many decades and there has been little advancement in the design of such packages. In order to diversify the options available to pharmaceutical companies and others who market small objects, there is a need for new CR designs that are ASTM certified.
Finally, it is necessary to minimize the packaging cost associated with pharmaceutical products. It is believed that low cost of traditional pill bottles has deterred market participants from utilizing new and different designs. Accordingly, it is desired to provide a package or container design that will offer a favorable cost relative to known CR packaging.
There have been attempts to provide updated CR packaging. For example, U.S. Pat. No. 8,333,288 discloses a child resistant container that includes a locking ring and a cap. The locking ring and cap are a two-piece closure system for a separate body of the container. This design is complex and therefore costly to produce and assemble.
PCT application No. WO96/23705 also discloses a child resistant container. The container has a post near its opening for engaging a slot on the cap, which also has a feature for puncturing a seal on the container. The slot is convoluted to varying degrees across the embodiments disclosed. However, the container has the appearance of a traditional pill bottle and the post and slot design may not provide sufficiently robust child-proofing.
Finally, U.S. Pat. No. 5,462,182 discloses a child resistant container, which includes a cap that screws onto a container and has push tabs that are biased outwardly or downwardly. Again, this container has the look of a traditional pill bottle.
Accordingly, there is a need for a child resistant container that has a modern and sleek appearance, that is usable for storing pharmaceutical pills but that does not have the appearance of a traditional pill bottle. What is further desired is such a container that can be manufactured and assembled for a cost that is comparable to traditional pill bottles. Finally, it is desired that such a container be suitable for certification as a child resistant container by one or more regulatory bodies.
It is an object of the present invention to provide a container that is child resistant, but which has a modern and sleek appearance.
It is another object of the present invention to provide a container that is cost effective to manufacture and assemble.
It is yet another object of the present invention to provide a container suitable for certification as a child resistant container.
These and other objects are accomplished by provision of a container according to a first embodiment of the present invention. The container comprises a body and a cap. The body includes a cylindrical portion, having a longitudinal axis associated therewith, an open end on the cylindrical portion, a slot, having a first section, at least a portion of which extends along an arc on the cylindrical portion having its center point on the longitudinal axis, and having a second section, and an opening adjacent to the slot. The cap is adapted to close the open end, and comprises a protrusion adapted to fit in the slot and a movable tab adapted to fit in the opening and spaced from the protrusion such that the tab engages the opening when the protrusion is in an end portion of the first section of the slot.
In some embodiments, the second section of the slot extends substantially parallel to the longitudinal axis. In some embodiments, the slot is “L” or backwards “L” shaped. In some embodiments, the slot is “J”-shaped.
In some embodiments, the tab comprises a sloped surface such that height of the tab increases from a lower edge of the tab to an upper edge of the tab. In some embodiments, the cylindrical portion further comprises a closed end, such that the cylindrical portion makes up the entirety of the body. In some embodiments, the protrusion is substantially rectangular.
In some embodiments, the body further comprises a first indication providing a first instruction for removal of the cap from the body, comprising an instruction to push on the movable tab. In some embodiments, the cap further comprises a second indication providing a second instruction for removal of the cap from the body, comprising an instruction to move the cap such that the protrusion travels along the first section of the slot. In some embodiments, the cap further comprises a third indication providing a third instruction for removal of the cap from the body, comprising an instruction to move the cap such that the protrusion travels along the second section of the slot. In some embodiments, the third instruction is obscured by the body when the protrusion is in the first section of the slot but is visible when the protrusion enters the second section of the slot.
In some embodiments, the container further comprises an o-ring that provides a seal between the cap and the body.
According to a second embodiment of the present invention, a container is provided that comprises a body and a cap. The body comprises a longitudinal axis, an open end, a slot having a section, at least a portion of which extends along an arc on the cylindrical portion having its center point on the longitudinal axis, and an opening adjacent to the slot. The cap comprises a protrusion adapted to fit in the slot and a movable tab adapted to fit in the opening and spaced from the protrusion such that the tab engages the opening when the protrusion is in the section of the slot that is substantially perpendicular to the longitudinal axis.
In some embodiments, the slot further comprises a second section that is substantially parallel to the longitudinal axis. In some embodiments, the body further comprises a cylindrical portion that includes the open end, the slot, and opening. In some embodiments, the cap further comprises a lid portion and a sleeve portion and wherein the protrusion and tab are formed on the sleeve portion.
According to a third embodiment of the present invention, a container is provided that comprises a body and a cap. The body, comprises a longitudinal axis, an open end, a slot having a first section, at least a portion of which extends along an arc on the cylindrical portion having its center point on the longitudinal axis and a second section connecting the first section to the open end, and an opening adjacent to the slot. The cap comprises a lid portion and a sleeve portion, including a protrusion adapted to fit in the slot and a movable tab adapted to fit in the slot and spaced from the protrusion such that the tab engages the opening when the protrusion is in an end portion of the first section of the slot.
In some embodiments, the first section is sized such that the cap must be twisted approximately 30 degrees to move the protrusion from the end portion of the first section to the second section. In some embodiments, that the second section is substantially parallel to the longitudinal axis. In some embodiments, the tab is movable toward a center of the cap and is biased to return to a starting position.
According to a fourth embodiment, a container is provided that comprises a body and a cap connectable to the body and requiring a first, a second, and a third movement to remove the cap from the body. The container also comprises a first indication on either the cap or the body providing a first instruction for the first movement for removal of the cap from the body. The container further comprises a second indication on either the cap or body providing a second instruction for the second movement for removal of the cap from the body and a third indication on the cap providing a third instruction for the third movement for removal of the cap from the body, the third indication only becoming visible upon completion of the first movement and second movement.
Other objects and features of the invention described herein and its particular features and advantages will become more apparent from consideration of the following drawings and accompanying detailed description.
The body 11 has associated with it a longitudinal axis 17. The axis 17 is the center axis of the cylinder that forms the body 13 or is the center axis of the cylinder associated with the cylindrical portion of the body 13. In the embodiment shown, the cap 12 also has a round cross section and the axis 17 would pass through the radial center of the cap 12 when it is aligned with the open end 13 of the body 11.
The body 11 also includes a slot 15 formed at the open end 13 and an opening 16 adjacent to the slot 15 and the end 13. As shown more clearly in
The slot 15 and the opening 16 are adapted to interact with features on the cap 12 to securely close the body 11. In the embodiment shown, the cap 12 is made up of a lid portion 20 and a sleeve portion 21. The sleeve portion 21 is sized to fit closely within the open end 13 of the body 11. In many advantageous embodiments, the sizing of the sleeve portion (or another portion of the cap) is selected to provide some degree of friction fit within the body 11. This provides a better seal of the interior of the container and reduces the likelihood of the cap being removed from the body unexpectedly. The lid 20 is sized to cover and close the open end 13. The sleeve portion 21 has a protrusion 22 formed thereon. The protrusion 22 is sized to fit in the slot 15 of the body 11. The sleeve portion 21 also includes a movable tab 23. The movable tab 23 is depressible in the direction of arrow 24, or, in other words, in the direction radially inward toward the axis 17.
The movable tab 23 is sized to fit within the opening 16 on the body 11. In the embodiment shown, the tab 23 is also generally rectangular and is sized such that it will fit snugly in the opening. In preferred embodiments, the movable tab is biased in the position in which it is shown in
In
The protrusion 22, slot 15, tab 23, and opening 16 cooperate to securely lock the cap 12 onto the body 11. To lock the cap 12 on the body 11, the cap is positioned near the open end 13 as shown in
In some embodiments, such as the one shown in the figures, the movable tab 23 has a sloped profile so that it will not hinder insertion of the sleeve portion 21 into the body 11. The sloped profile means that the height of the tab 23 increases from its lower edge 25 to its upper edge 26. The tab 23 is also movable in the radially inward direction so that, as the sleeve portion 21 is inserted, the rim of the open end 13 pushes the tab 23 inward.
To remove the cap 12 from the body 11, the user pushes the movable tab 23 inwardly until it clears the opening 16. Although the protrusion 22 and slot 15 prevent the cap from being pulled out of the body 11, once the tab 23 is pushed inwardly, the user can then twist the cap 12 so that the protrusion 22 moves along the first section 18 of the slot 15 toward the second section 19 of the slot 15. Once the protrusion 22 reaches the second section 19, the user can pull the cap off of the body. The first section of the slot 15, though it may take varying shapes, is nevertheless designed such that a twisting movement must be applied to the cap at some point before it can be fully removed from the body.
In the embodiment shown in
The embodiment of
In preferred embodiments, the container is adapted to be sealed against the intrusion of moisture when closed. This is particularly important when the container is intended as a package for pharmaceutical or medical products. In the embodiment shown in
In most embodiments, the cap 12 and body 11 are formed from plastic materials. In preferred embodiments, the materials are certified as medical grade, suitable for packaging pharmaceutical products. In some embodiments, the materials are sufficiently opaque to protect the contents of the container from interaction with ultraviolet or other light and/or to shield the contents from visibility to the naked eye. As will be apparent to those of ordinary skill in the art, however, the components of the container can be formed from any material that is suitable for the intended application of the container.
Second, the o-ring seal 130 is on the lower part of the sleeve portion 121 of the cap 112, instead of near the junction of the sleeve portion 121 and the lid portion 120 as in other embodiments. This is because the cap 112 must travel first into the body 111 when being secured to the body, and then moved back a certain distance out of the body 111 in order to seat the protrusion 122 at the end 132 of the slot 115. The result, shown in
The design of the embodiment shown in
The embodiment shown in
As will be apparent to those of skill in the art, the container of the present invention need not be entirely cylindrical. For example, as shown in
The invention can be applied to containers of a variety of sizes. With respect to the embodiment shown in
Some embodiments of the invention, including the one depicted in
Accordingly, embodiments of the present invention provide modern looking containers that meet ASTM requirements. These containers are inexpensive to manufacture and assemble and durable for extended use. Although the invention is particularly well-suited to use with medical or pharmaceutical products, it is also advantageous for use with switches, bolts, screws, or any other object for which secure packaging and storage is desired.
Although the invention has been described with reference to particular embodiments and arrangements of parts, features and the like, these are not intended to exhaust all possible embodiments, arrangements, or features, and indeed many other modifications and variations will be ascertainable to those of skill in the art.
