The present invention relates in general to containers for storing and dispensing various products, and in particular, to portable, hand-held containers for storing and dispensing viscous fluids such as paint, cleaning fluids, laundry products, and beverages, to name a few.
Containers for holding viscous and other fluids are known in the art. Particularly, with respect to the paint industry, nearly all generally one-gallon and smaller paint containers are sold in cylindrical metal cans having an upper edge with a U-shaped channel that accepts the annular protrusion of a high friction metal lid secured by a press fit. This arrangement has numerous operational drawbacks that have not been addressed by the industry.
One such operational drawback is the difficulty in pouring paint from the can into a tray or other paint receptacle. The can lip makes a particularly poor spout. When the paint is poured from the can, paint must be poured across the U-shaped sealing channel on the upper edge of the can. This U-shaped channel inherently retains some of the paint which is discussed in greater detail below. Also, because of the circular shape of the container opening and the U-shaped channel, it is difficult to control the pourability of the paint, thus leading to paint running down the outside of the container. This is especially true when the container is full. This greatly adds to the spilling of sizable quantities of paint.
Further, in using the container itself as a paint receptacle, users often dip paint brushes directly into the container and use the inner edge of the container opening to wipe excess paint from the brush. The circular shape of the can opening is particularly ineffective for wiping a flat brush clean of excess paint. Further, this also causes paint to gather in the annular U-shaped channel.
As paint collects in the U-shaped peripheral channel, resealing the lid becomes particularly messy as the captured paint may splatter when the lid is pounded back onto the can. Further, paint in and around the channel can dry and flake, leading to paint contamination each time the can is jostled. The pounding of the lid can also damage the sealing surfaces, which again can cause the seal to fail. Further, if the paint in the U-shaped channel dries, it may prevent the air-tight seal of the lid and the can and allow the paint therein to dry out or skim over, thus leading to the waste of the remaining paint. After repeated opening, pouring, and closing, the mating surfaces of the can and lid will eventually become fouled leading to the failure of the friction seal. Another drawback for metal paint cans is that while metal cans are coated to prevent rust, this coating often fails, which leads to rust and paint contamination.
Other such drawbacks include the lack of a locking mechanism that would prevent the friction lid from popping off if the can is dropped from a height as little as one meter, with consequent spilling of the contents widely on the ground. The lid, moreover, must be pried off with a tool to gain access to the paint, which proves a problem if no tool is available. The prying action, moreover, often damages the U-shaped channel lid sealing surface.
Another drawback in the construction of such metal paint cans is that the inner lip of the container opening traps paint as it is poured, thereby preventing the user from being able to extract all available paint from the container during pouring or even if a brush is used.
Many efforts have been made to address these and other problems associated with the conventional metal paint can. Some prior art improvements remedy to a degree some of the shortcomings mentioned above, but none, until the present invention, has effectively solved even a majority of these problems.
The present invention, on the other hand, synergistically solves nearly all of the major problems above-enumerated inherent in the conventional metal paint can. The present invention will be more fully described in the following written description with reference to the accompanying drawings.
Reference is now made to the drawings. Without limiting scope of the present invention, the invention herein is described with regard to its use as a paint container.
However, it is obvious that the improved container of the present invention could be used for holding or dispensing numerous contents including other viscous or powdered products or any product requiring a container for dispensing.
However, it is possible to integrally mold the spout member 12 and the container body 14 as one piece. Nevertheless, utilizing a separately molded spout member 12 enables one to utilize the entire opening of the container body when filling the container body and then connecting the spout member 12 to the container body 14 for use.
As shown in
Referring to
As best shown in
The downwardly facing sealing surface located on the underside of the lip 18 may also include a sealing member located within the groove to assist in sealing the spout 12 with respect to the container 14.
The spout/paint return structure 20, shown best in
Spout wall 16 also includes at least one notch 13 formed therein which engages a protrusion 15 extending from the container 14 so as to properly orient the spout 12 with respect to the container 14 and prevent the rotation of the spout 12 when it is set within the container 14. Further as see in
As shown in
The lid 10 also includes a downwardly extending annular plug seal 37. The plug seal 37 slidably engages the inner diameter of the lip 18 of the spout 12 as an alternate seal between the lid 10 and the spout 12. The lid 10 further includes a radial seal shoulder 37 designed to place the outside diameter of the spout 12 under radial compression to improve the seal between the spout/lid and spout/container interfaces. The lid 10 may further include a concentrator step 39 to work in conjunction with the seal beads of the spout. The concentrator focuses axial loading of the lid into the spout seal beads which in turn bear down onto the bottle opening land surface of the rim during threaded engagement between the lid and the container opening. The lid also includes serrations/ribs 7 to the top portion of the lid to provide an improved surface for capping equipment while reducing the visibility of “rubs” or scrapes in the event the capping chucks spin against the lid.
The container assembly may also include a one-piece molded handle, shown in
As indicated above, by employing at least one sealing bead located on the downwardly facing sealing surface of the spout member lip, the sealing bead works in combination with a properly placed lid component. When in proper assembly, the spout and lid will be in vertical compression against the rim of the container creating a secure seal to contain the product within the container.
The invention has been described with reference to the preferred embodiment. Obviously, modifications and alternations will occur to others upon a reading and understanding of this specification. The claims as follows are intended to include all modifications and alterations insofar as they come within the scope of the claim or the equivalent thereof.
This application is a continuation of U.S. patent application Ser. No. 10/419,693, filed Apr. 21, 2003, which is hereby incorporated by reference and which claims priority from U.S. Provisional Patent Application No. 60/373,939 filed Apr. 19, 2002.
