(1) Field of the Invention
The present invention relates to a container clip.
(2) Description of the Related Art
Commercially available filled containers, such as infant feeding bottles, are typically packaged and sold in groups of more than one container. Paperboard cartons or shrink-wrapped trays are typically employed as the carrier for such grouped containers. Such packaging is designed to protect the containers from being separated from one another and from damage during shipment, handling, and storage.
However, this type of packaging does not always provide the best display for the containers while they are in inventory on store shelves. Additionally, upon purchase of the packaged containers, the consumer must open the packaging and remove a container. Unfortunately, once the paperboard carton or shrink-wrapped tray is opened, the carton or tray can no longer securely retain the remaining containers and the containers are permitted to move freely inside the packaging, causing them to become susceptible to damage or mishandling.
A need exists for an improved packaging assembly for retaining, distributing and re-storing containers after use. A need also exists for a packaging device which functions as a means to stabilize containers during shipment and display containers while in inventory. The present invention addresses these needs.
Briefly, therefore, the present invention is directed to a novel packaging clip for retaining a plurality of containers. The clip comprises a rectangular frame made of a resilient material and having length and width dimensions. The rectangular frame has a plurality of circular apertures having an open mouth and two arms adjacent to and forming the open mouth. The number of arms is one more than the number of circular apertures.
The circular apertures are adapted to receive and retain a container between the arms, and have inner diameters that are substantially equivalent to the diameters of the containers to be retained by the clip. The open mouths of the circular apertures are positioned along the length dimension of the frame so that the mouths open in only one direction. Additionally, the open mouths of the circular apertures are smaller than the inner diameter of the circular apertures and smaller than the diameter of the containers to be retained by the clip.
The invention also relates to a packaging assembly having a clip as described above and including a plurality of containers retained within the circular apertures of the clip.
The present invention is also directed to a clip for retaining a plurality of containers, the clip comprising a frame having a length dimension and a plurality of arms extending from only one side of the frame length. The frame length, a flexible arm and a relatively fixed arm form at least one circular aperture adapted to receive and retain a container. The invention also relates to a packaging assembly having a clip of this type which also includes a plurality of containers retained within the circular apertures of the clip.
Among the several advantages found to be achieved by the present invention is that it is adapted to receive and retain a plurality of containers. After one or more containers are removed from the clip of the present invention, the clip allows any remaining containers to remain secure. Containers can be firmly reattached to the packaging device with ease by inserting a container into an aperture. These benefits eliminate the possibility of damage or mishandling due to unsecured containers. The present invention also provides a device that stabilizes containers during shipment and appropriately displays containers while in inventory.

Referring to
The rectangular frame 20 has a plurality of circular apertures 50 which each have an open mouth 60 and two arms 21 adjacent to and forming the open mouth 60. The arms 21 extend substantially perpendicularly from the length dimension 30 of the rectangular frame 20. The open mouth 60 is defined as the space running directly between two adjacent arms 21. The number of arms 21 on a particular frame 20 is one more than the number of circular apertures 50. For example, if the clip has three circular apertures 50, it will have four arms 21. This is the case because each of two adjacent apertures 50 shares a common arm 21 therebetween.
The circular apertures 50 are adapted to receive and retain a container 200 between the arms 21, and have inner diameters 90 that are substantially equivalent to the diameters 210 of the containers 200 to be retained by the clip 10. Additionally, the open mouths 60 of the circular apertures 50 are smaller than the inner diameter 90 of the circular apertures and smaller than the diameter 210 of the containers 200 to be retained by the clip.
The open mouths 60 of the circular apertures 50 are positioned along the length dimension 30 of the frame so that the mouths open in only one direction. Thus, the apertures 50 are positioned along only one side of the length dimension 30 of the frame. In some embodiments, the opposite side of the frame length 30 is straight or has another design without apertures.
The width of the mouth 60 of the circular aperture 50 should be sized such that a container 200 can be inserted through the mouth 60 and the frame 20 surrounding the circular aperture 50 can grip the container 200 and retain it in place. The exact ratio of the width of the mouth 60 to the diameter 90 of the circular aperture 50 or the outside diameter of the container 200 will depend upon the material from which the clip is formed and the flexibility of that material. In a particular embodiment, the diameter 90 of the circular aperture 50 is approximately equivalent to the outside diameter of a container 200 it is designed to receive and retain.
In some embodiments, the width dimension 40 of the rectangular frame 20 is approximately equivalent to the diameter 90 of the circular aperture 50. In other embodiments, the width dimension 40 of the rectangular frame 20 is greater than the diameter 90 of the circular aperture 50.
The clip 10 of the present invention can be used to receive and retain cylindrical containers, as shown in
In certain embodiments, the clip 10 of the present invention has at least two circular apertures 50. In other embodiments, the clip has three circular apertures 50.
A packaging clip in accordance with the present invention has dimensions that are dependent upon the container it is designed to retain. In certain embodiments of the clip 10, the distance 80 from the midpoint of a first circular aperture 50 to the midpoint of a neighboring second circular aperture 50 is approximately 1.4 times the diameter 90 of the circular aperture 50.
In a particular embodiment, the clip has three circular apertures 50 and is approximately 14.7 cm in length 30. In this embodiment, the width dimension 40 of the clip is approximately 3.4 cm. The diameter 90 of the circular aperture 50 is approximately 3.4 cm. The distance 80 from the midpoint of a first circular aperture 50 to the midpoint of a neighboring second circular aperture 50 is approximately 4.7 cm. The distance between the edge of the mouth 60 of a first circular aperture 50 to the closest edge of the mouth 60 of a neighboring second circular aperture 50 is approximately 2.1 cm
As shown in
A container 200 can be retained by the clip 10 by inserting the container 200 into an aperture 50. The resilient frame 20 flexibly adjusts to receive the container 200 in the aperture 50. In certain embodiments, the ability of the arms 21 to move depends on the flexibility of the frame 20 itself. In a particular embodiment, the rectangular 20 frame flexibly adjusts at the base 70 of each circular aperture 50 to receive the cylindrical container 200. Once the container has been inserted into the aperture 50, the frame 20 flexibly returns to its original position, securely retaining the container. The gripping surface 25 of the frame which creates the circular aperture 50 frictionally grips the outside of the container 200.
A container 200 can be released from the packaging clip 10 by simply pulling the container 200 away from the frame 20 through the mouth 60. Again, the resilient frame 20 flexibly adjusts to release the container 200 from the aperture 50. In a particular embodiment, the rectangular 20 frame flexibly adjusts at the base 70 of each circular aperture 50 to release the cylindrical container 200. Once the container has been released from the aperture 50, the frame 20 flexibly returns to its original position.
In an embodiment, the frame length 20 is substantially flat and has sufficient rigidity to support at least three containers 200 without becoming distorted. In a particular embodiment, the packaging clip of the present invention has a handle fixedly attached to the frame length (shown in
In an embodiment, the containers 200 can have a middle body portion 202, an upper body portion 203 and a lower body portion 204. The upper body portion 203 and the lower body portion 204 have a diameter that is greater than the diameter of the middle body portion 202. The upper body portion 203 prevents the container 200 from slipping out of the packaging clip 10. The wider lower body portion 204 provides stability for standing the container 200 on its end. The containers 200 can also have a closure 205.
The containers of the present invention can be bottles, such as infant feeding bottles. In an embodiment, the containers comprise bottles containing infant formula. In another embodiment, the containers comprise empty bottles designed to be filled with human breast milk and stored. The bottles can be adapted to receive a nipple and can be used to feed an infant. The bottles can then be washed, inserted into the clip of the present invention and stored empty or can be re-filled, inserted into the clip of the present invention and stored full.
If desired, a packaging assembly 100 according to the invention could be enclosed in plastic or shrink-wrap. Similarly, the packaging assembly 100 could have the bottoms of the containers resting in a tray, such as a cardboard tray. Optionally, the packaging assembly could have the bottoms of the containers resting in a tray which could then be enclosed in plastic wrap. In another embodiment of the invention the packaging assembly could be packaged in a cardboard container. In a particular embodiment, the packaging assembly is packaged within a flexible pouch. The pouch can have printing present thereon. In an embodiment, the flexible pouch is comprised of a plastic.
An alternate embodiment of the present invention is shown in
A container 200 can be retained by the clip 310 by inserting the container 200 into an aperture 350. The resilient frame 320 flexibly adjusts to receive the container 200 in the aperture 350. In this embodiment, however, the flexible arm 321 also flexibly adjusts to receive the container 200. In a particular embodiment, the rectangular frame 320 may also flexibly adjusts at the base of each circular aperture.
In certain embodiments of the invention, the packaging clip 310 has an insertion aid 324 on the terminal end of each flexible arm 321. The insertion aid 324 enhances the ability of the user to insert the containers 200 into the packaging clip 310. Specifically, as the container is inserted into the clip, the insertion aid helps to guide the container into the open mouth 50. Although the insertion aids 324 are shaped in a particular manner in the drawings, the insertion aids of the invention may encompass various shapes. The insertion aids can be of any shape that enhances the ability of the ability of the user to insert the containers 200 into the packaging clip 310.
For purposes of the invention, a square frame can also be considered rectangular. In certain embodiments of the invention, the frame can be other shapes as well, such as ovular or round. The frame may have rounded or sharp edges.
The packaging clip of the invention is made of a resilient material. This material may be any such material that is capable of flexibly adjusting. The packaging clip of the present invention may be molded of a suitable plastic material, which may be blow molded by extrusion or injection so that it is a unitary member of relatively uniform wall thickness. Any plastic material known in the art can be used to form the packaging clip. A suitable plastic for forming the packaging clip may include, but is not limited to, polystyrene, polystyrene-acrylonitile, acrylonitile-butadiene-styrene, styrene-maleicanhyd ride, polycarbonate, polyethylene terephthalate, polyvinylcyclohexane, and blends thereof.
