The present invention relates to pouring spouts, and more particularly to retractable spouts for paint cans.
It is well known to persons having an ordinary skill in the art that pouring paint from containers can be a messy operation. The contents invariably drip or run down the outside of the can during pouring and subsequently must be wiped with a rag or paint brush before running down the can and onto the floor. Paint is also necessarily mixed prior to use and most painters use paint mixing sticks to accomplish this task before pouring the paint into a small hand held paint container, roller tray or paint sprayer. Accordingly, paint is liable to spill during the mixing operation even before it is poured.
Also, while mixing or pouring, paint tends to pool in the annular closure channel around the can opening and subsequently affects the seal when the lid is reapplied. Common paint cans typically have a lid with an annular ridge protruding from the bottom side of the lid that seats within the closure channel in the rim of the can by a friction fit. Accordingly, when paint pools within this channel, the lid cannot properly seat within the channel and the can cannot be properly sealed. Without an improved device to prevent pooling, the painter must wipe the pooled paint from the channel before it hardens and it is no longer possible to effectively seal the can.
Because of the mess associated with pouring paint from cans and the extra cleanup that the painter must complete after pouring and mixing, there has been a desire for an improved spout that prevents paint from spilling down the side of the paint can during mixing and pouring, as well as pooling in the closure channel of the can rim.
Current conventional paint cans generally have two primary functions. The first function is to store paint so that it can be manufactured, transported, displayed, sold to a consumer, opened for use and resealed for storage and use at a later time. Its second function is distributing its contents whether with a brush or dispensing to a small hand held paint container, roller tray or paint sprayer. As stated above, the second function often times leads to spilling and therefore persons having an ordinary skill in the art desire to have an improved can or spout to combat these issues.
Most known devices on the market attempt to resolve these dispensing and mixing issues by externally mounting spouts and other devices to the inner edge of the paint can rim, which can be removed after use. For example, U.S. Pat. No. 2,767,891 describes a spout for a paint can that is removably attached to the rim of a paint can to prevent spilling during pouring. However, devices like the '891 patent necessarily require the painter to attach the device prior to pouring and remove the device after pouring is completed, and subsequently require additional cleanup of the removable spout after it is used and the can needs to be resealed. These externally mounted spouts do not allow for the can to be resealed when the device is in place, as most of the known spouts mount to the can around the rim and thereby prevent the protuberance of the lid from seating within the closure channel. Lastly, known pouring spouts, such as that described in the '891 Patent, are not intended to and do not prevent paint from pooling in the closure channel around the can opening, especially during mixing.
For example, the Shur-Line® Pour and Store Lid and the SnapNSave™ are externally mounted spouts currently on the market that attach over the entire rim of the can and replace the existing friction fit lid. The problem is that they have to be installed and removed constantly because paint requires periodic mixing and these devices do not allow access. Also, these pouring spouts are not intended to and do not prevent paint from pooling in the closure channel around the can opening while paint is mixed. Additionally, the seal of these pouring spouts are not as good as the friction fit lid that is standard with the existing paint can. Often, these devices do not perfectly fit all gallon paint cans because rim sizes are slightly different depending on the manufacturer, which leads to paint dispensing mishaps that result in the loss of large amounts of paint or cans being stored without a complete seal leading to the loss of the remainder of the paint.
The Shur-Line® Pour and Store Lid and the SnapNSave™ spouts also fail to allow use of the container's original lid. In both designs, the pouring spouts replace the standard container lid and include corresponding lids that engage the respective spouts, requiring the user to necessarily discard the original container lid. Further still, neither spout design can be retracted into the can and covered with the original lid. In the SnapNSave™ spout in particular, a planar lid is provided in place of the original paint can lid so that multiple cans can be stacked on top of one another. Accordingly, it would be beneficial to have a pouring spout that can both retract inside the can and function with the traditional can lid to allow paint cans with a spout to be stackable.
Other known devices attempt to solve pouring and mixing issues by integrating a retractable spout within the paint can, rather than having the painter attach the removable spout to the outside of the can. For example, U.S. Pat. No. 2,498,318 describes a retractable spout that freely floats within the paint can when not in use and can be pulled to the top of the can before pouring. Accordingly, the painter does not necessarily need to attach the spout prior to use and does not need to clean the spout after use, as it may remain within the can. However, there is nothing in the device of the '318 patent preventing the spout from falling to the bottom of the can, and it must be fished out and pulled to the top of the can before pouring. Additionally, when the spout is extended, it will be covered in paint, which will drain down the spout into the can rim and pool in the closure channel, thereby affecting the seal of the lid once the spout is retracted. Also, devices like these would require installation by the manufacturer and have the potential to negatively impact the mixing of the paint by the retailer since the spout would impede the flow of paint during the mixing or shaking process in the store.
Similar cans with integrated spouts include those described in U.S. Pat. Nos. 3,831,824 and 1,836,729, which effectively aid with pouring liquids from cans but which necessarily require the design of the can to be modified. Particularly, the lids of the '824 Patent and the '729 Patent are necessarily altered to accommodate the integrated spout. Accordingly, these integrated spouts are not fit for use with traditional paint cans and similarly do not allow easy mixing, which is a function of traditional paint cans. Other attempted solutions to these issues include new designs for the container, which involve changing its shape, size and assembly. These changes are very expensive to implement because they require significant changes to the existing infrastructure, including container fabrication, packaging, assembly lines, shipping layouts, storage layouts and shaker devices.
Accordingly, there remains a need for an improved spout for a paint can that can be integrated with traditional paint cans, while preventing spilling during pouring and mixing, in addition to allowing the traditional paint can to seal without modifying the original exterior of the container, specifically a traditional metal, plastic, or hybrid paint can.
The present disclosure describes a pouring assembly for a liquid container and particularly for a spout for pouring liquid, as well as other uses, from a container. For example, pouring paint from a traditional pint, quart or gallon paint can having an opening at one end. In the preferred embodiment, the pouring assembly includes a retractable spout that prevents spilling and pooling of liquid within the rim of traditional paint can and allows easy reclosing of the container with a traditional paint can lid. Where no paint pools within the channel, the lid seals in a tight manner and prevents deterioration of the remaining contents of the container, while also mitigating any loss of paint and mess during use. These functions are achieved without modifying the can or lid structure, thus maintaining the original paint can structure as manufactured, including an annular seal for a removable lid that has a friction fit engagement with a corresponding annular channel.
Another aspect of the disclosure is to provide a novel spout, which when extended functions to increase the interior volume of the container to facilitate the mixing of the contents with a mixing device, for example a wooden mixing stick, paddle mixer or similar device. This additional interior volume of the container may also be utilized to clean and remove excessive contents, such as paint, from said mixing devices. Particularly, the disclosed spout may include a brush wipe for removing excess paint from a brush after it has been dipped into the paint can.
Another aspect described herein is the novel spout that can be extended to facilitate the pouring of the contents, for example paint or stain, without dripping the paint or stain down the outside of the container or affecting the closure channel around the rim of the can once the pouring operation is complete and the can needs to be resealed. Accordingly, any excess liquid remaining on the extended spout after pouring will drip back into the container and away from the rim of the can. And once retracted, the spout is able to remain inside the container so that the spout does not necessarily need to be attached, removed and reattached to the can. Also, the spout does not require any cleaning after each use and the paint does not dry on the spout because it remains fluid inside the paint can. Since the paint can is able to be resealed easily, the paint remaining in the can does not deteriorate from being left open to the outside air which minimizes paint loss and contamination of the paint like dried flecks in the paint that are created on the inner edge of the can when left open. This dried paint inevitably flakes into the can fouling the remainder of the paint and in some instances, requires the paint to filtered to remove the contaminants.
A further aspect of the pouring assembly described herein is to provide an inexpensive container spout of simple plastic or metal construction that may be permanently or semi-permanently mounted inside of a conventional container in a retracted position. If permanently mounted inside the can, the spout would still allow the container to be sealed in its current design with no modifications to the closure, no additional openings in the container that could lead to deterioration of the remaining contents of the container, and no necessity for modification to the exterior size and shape of the container, thus allowing current assembly and manufacturing infrastructure to be used without conflict or with minimal modification. If semi-permanently mounted inside the can, the spout would still allow the container to be sealed in its current design with no modifications to the design of the closure and no necessity for modification to the exterior size and shape of the container, thus allowing current assembly and manufacturing infrastructure to be used without conflict or with minimal modification.
Further areas of applicability of the devices and methods of the present disclosure will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, which include the preferred embodiment thereof, are intended for purposes of illustration only and are not intended to limit the scope hereof.
The present invention disclosure will become more fully understood from the detailed description and the accompanying drawings, wherein:
The following description of the preferred embodiment(s) is merely exemplary in nature and are in no way intended to limit the invention, its application, or uses.
Example implementation of the pouring assembly in accordance with various embodiments described herein includes a retractable spout for a container. Preferably, the pouring assembly combines a spout and an annular collar with a container having a lid that seals with a friction fit in the rim of the container. In operation, the spout translates relative to the opening of the container and engages one of the rim of the container or the collar of the pouring assembly in both retracted and extended positions. The spout can be extended from the container opening to assist in pouring or provide additional container volume for mixing. Once the pouring or mixing operation is complete, the spout is subsequently moved into the retracted position within the container for later use. Subsequently, the container can be sealed with the original lid while the spout is held within the container with the top edge of the spout positioned proximate to the container opening for easy access when the container is needed again.
When in the extended position, the spout will function to increase the interior area of the container to facilitate the mixing of the contents so as not to foul the closure channel or annular rim with paint, such as while stirring with a mixing device, for example, a wooden mixing stick, paddle mixer or any similar device. This additional space also allows for a more aggressive stirring of the contents to achieve a better mix of said contents. In addition, this additional interior area of the can may be utilized to clean or remove excessive paint from said mixing devices for deposit back into the can. For example, a mixing stick used for stirring may be slidably pressed against the flat edge of the handle described below to expel paint therefrom. The additional interior area provided by the extended spout makes cleaning a mixing stick significantly easier than if using a paint can without the spout installed.
When the spout is fully extended for pouring or mixing, the bottom flange will nest and seal against the ledge bottom side of the annular collar to prevent paint from pouring out anywhere except through the opening in the spout. In the extended position, the spout projects outside of the can past the annular container rim so that when contents are poured from the can, the contents flow past the outer rim edge of the can without contacting the rim top side and exterior container sidewall of the can or fouling the annular rim and closure channel. This feature reduces or eliminates cleaning and prevents problems closing the can with the paint can lid, for example when paint has dried in the closure channel or annular rim of the can so as to interfere with the nesting of the friction fit lid.
Once dispensing of the paint is complete, the spout may be retracted back into the can by pushing down on the top edge of the spout or the handles with the user's fingers or other tool, such as a church key or a screwdriver. The tools can be utilized if the user does not want to get paint on their fingers or hands. Once the spout is retracted into the paint can, any paint remaining on the spout will drain back into the can through the gap between the spout and the ledge. The painting cycle is completed when the can is resealed with the lid. The protuberance in the lid may be frictionally fit into the closure channel of the rim or collar as described below, thereby facilitating the reclosing of the can in a tight manner to prevent deterioration of the remaining contents of the can. The spout remains in the can and ready for future use. The paint on the spout remains fresh and fluid just like the paint in the can which prevents any contamination of the paint from paint drying and flaking off into the paint which would show up during future painting and possibly ruin the paint finish.
As particularly shown in the Figures, the pouring assembly 10 is attached to a container 100, with the spout 12 positioned within the interior volume of the can and engages the rim 102 of the container or a collar 14 as further explained herein. The pouring assembly is preferably used with a conventional paint can, but it will be appreciated by those having an ordinary skill in the art that the spout may be used with any container having a suitable opening for dispensing a liquid and employing the spout.
The container preferably includes a cylindrical can body with a circumferential bottom on one end and an annular can opening on the other. The can has a single opening proximate to the top of the cylinder defined by the rim. The can opening is surrounded by a rim having a rim closure channel 114 that accepts the lid protuberance 108 when the can is sealed. The rim radially extends from the outer edge 112a connected to the sidewall 104 of the cylindrical body to an inner edge 112b positioned within the cylindrical can body. The annular closure channel is subsequently spaced a distance 116 from the outer rim edge between the inner and outer rim edge and the friction fit lid nests within the annular closure channel in the closed position.
Accordingly, the preferred container also includes a traditional paint can lid 106 that has a lid protuberance 108 proximal to the periphery of the lid that mates with the rim of the can. In operation, the lid protuberance seats within the annular closure channel of the rim and is secured with a friction fit. Alternatively, as further explained below, the lid protuberance seats within the annular collar channel 44 in embodiments having a top mount collar 14a. Regardless of the assembly embodiment, when the lid is removed, the opening at the top of the can permits access to the paint contained within the can and the can is sealable with the originally provided lid.
The spout is receivable within the container and includes a cylindrical sidewall 30, a top 28a and bottom 28b edge, a bottom flange 32 protruding from the bottom edge and at least one tab protruding from the top edge. Preferably, the sidewalls of the spout form a solid cylindrical body 12a but it will be appreciated that other spout configurations may be used as further described herein. The tabs 16 are positioned proximate to the top edge of the spout and extend a tab width 50 from the exterior sidewall. Preferably, the tabs include a flat bottom portion 72a for engaging the collar ledge. The bottom flange protrudes a bottom flange width 48 from the exterior sidewall 30a of bottom edge of the spout, opposite from the tabs. As further described herein, the spout is supported by the tabs as they rest on the rim of the container when the spout is in the retracted position. Conversely, the bottom flange 32 engages the bottom side 110b of the rim when the spout is extended. Further still, the flange may also have a curved shape for embodiments that seal against the irregularly shaped bottom side of the rim.
In operation the spout translates between an extended position 26b and a retracted position 26a relative to the rim of the container. When the spout is retracted, the tabs engage a topside 110a of the rim and suspend the spout from the rim with the top edge of the spout proximate to the can opening. However, the top edge of the spout does not interfere with the rim channel so as to allow the friction fit lid to seal without interference. In the retracted position the bottom flange is disengaged from the bottom side of the rim. In the extended position, the top edge of the spout protrudes through the can opening and the bottom flange sealingly engages the bottom side of the rim. When fully extended, the bottom flange prevents the spout from being pulled completely through the opening. Thereby, liquid may be poured from the container while the extended spout prevents liquid from spilling down the side of the can body or unintentionally entering the annular closure channel of the rim, as described further herein.
The pouring assembly may also include a collar attached to the rim of the container. As particularly shown in the drawings, the collar can be a top mount collar or a bottom mount collar. As shown in
Regardless of the particular collar embodiment, the collar includes an outer collar edge 38a positioned proximate to the outer edge of the rim, an inner collar edge 38b positioned proximate to the inner edge of the rim and a ledge 20 that radially extends a ledge width 52 from the inner collar edge beyond the inner edge of the rim and into the opening of the container. The ledge includes a topside 20a and bottom side 20b which respectively engage the spout tabs and the bottom flange as the spout moves between the retracted and extended positions. As explained with reference to the rim of the container above, when a collar is included in the pouring assembly the tab engages the topside of the ledge and the bottom flange is disengaged from the bottom side of the ledge when the spout is in the retracted position. Conversely, the bottom flange sealingly engages the bottom side of the ledge and the tabs are disengaged from the topside of the ledge when the spout is in the extended position. In addition, the ledge of the collar can also be slightly sloped to drain contents back into the can when the spout is retracted, as further described herein. Similarly, the bottom flange 32a may also be sloped to match the slope of the ledge in order to provide an improved seal.
In the embodiment shown in
The collar embodiment shown in
As shown in
In addition, collar tool cutout openings or a recess in the outer edge of the collar or a space 46 between the bottom side of the collar below the outer collar edge and the outer rim edge can be incorporated to allow for the easy removal of the device by inserting a standard church key or screwdriver into the opening, recess gap or space. Once inserted, the collar can be removed by pressing down on the rim and pushing up against the annular collar which will pull the collar protuberance out of the rim closure channel.

In another alternative embodiment shown in
In the alternative embodiments shown in
As shown in
In the embodiments illustrated in
The annular collar is preferably continuous around the rim of the can with the ledge protruding into the container opening to support the retractable spout. Accordingly, the ledge has a diameter that is less than or equal to the diameter of the rim. The preferred spout design includes an upper body portion 36a and a lower body portion 36b which respectively have differing diameters as particularly shown in
The narrowed upper portion of the spout creates a gap between the ledge of the annular collar and the spout when the spout is in a retracted position so as to allow any paint that spills between the spout and inner edge of the collar to drain back into the interior of the can when the spout is in the retracted position. Conversely, as the bottom portion of the spout has a substantially equal diameter to the inner diameter of the annular collar, when the spout is extended the exterior sidewall of the bottom portion of the spout scrapes against the edge of the annular collar and any paint thereon is thereby scraped from the spout and returned to the interior of the can. In addition, the bottom portion of the spout may have a friction fit between the exterior sidewall of the spout and the inner edge of the collar ledge where the ledge and bottom portion diameters are substantially equal. Thus, the spout friction fit further secures the spout in the extended position but it is preferred that another locking feature, such as the guiderail friction fit, ball detent or slide lock is provided wherein the diameter of the containers may vary in size.
In another aspect of the pouring assembly, a guiderail 18 protrudes from the exterior sidewall of the spout between a top end 18a proximal to the top edge of the spout and the bottom end 18b proximal to the bottom flange of the spout. In operation, the guiderail translates through a notch 24 in the ledge of the collar and prevents the spout from unwantingly rotating within the assembly. Two notches in the ledge serve as guide openings for corresponding guiderails on the sidewall of the spout. These notches located on the centerline of the can and may be aligned with the container handle 118a and attachment ears 118b to maintain the desired orientation for pouring the contents with the spout. As shown in the Figures, the guiderail is preferably positioned beneath the center tab which also aligns with the container handle attachment ears but it will be appreciated that the guiderail may be positioned at any location on the exterior of the spout. Further, the notch identifies the correct installation alignment for the spout particularly when a pouring lip is provided on the top edge of the spout as explained below.
Although the position and number of guiderails may vary, the preferred embodiment includes two guiderails and at least two corresponding notches preferably located on each side of the pouring spout in order to maintain a desired orientation of the spout relative to the can to ensure proper pouring of the contents with the spout. For example, in the embodiments shown in
Among other purposes, guiderails minimize the amount of frictional contact between the annular collar and the spout when the spout is in the retracted position by providing a gap so that the spout does not become fixed or attached to the annular collar if the paint thereon dried while the spout was retracted. Prying the spout will free these guiderails from the collar as noted below.
The top edge of the spout may also include an annular pouring lip 80 that provides a drip point on the exterior top edge of the spout to minimize paint dripping when pouring. When mixing openings 82 are provided within the spout, it will be appreciated that the pouring lip is on the opposite side of the spout body as shown in
Further, the guiderails may also include one or more features to hold the spout in the extended position. For example, the guiderail may be sized to provide a friction fit 62 with the notch and thereby hold the spout in the extended position. Further, a ball detent 60 may be provided on the bottom portion of the guide as shown in
In the alternative embodiment shown in
In operation the spout guiderails translate within the notch 24 of the collar as it is raised from its retracted position. However, when the spout is fully extended, the spout rotates and the collar ledge slides within the space between the top of the bottom flange and the bottom edge of the guiderail into a locked orientation when the guiderail hits the lock stop 68b on the ledge that is offset from the notch. This system allows the spout to be raised and subsequently twisted into a locked orientation to allow the user to know that the spout is in its proper pour position as well as hold the spout in the extended position.
In embodiments having the sliding lock, it will be appreciated that the collar and spout alignment within the can will change to facilitate the proper pouring position. To assure the pouring assembly is properly aligned within the container, collar embodiments may include alignment guides as shown in
Planar handles 34 are provided on the interior sidewall 30b of the spout proximate to the top edge, as shown in
In addition, the spout may also include a number of mixing openings 82 on one side, as shown in
The alternative embodiment shown in
Regardless of whether the collar is integrated during manufacturing as shown in
As shown in
Alternatively, the annular collar may not be integrated into the can and instead snaps into place as a permanent or removable attachment where the collar may be sold as an aftermarket product. In this embodiment, the inner edge of the paint can remains in its current design and the annular collar snaps into place over the inner edge and can be designed to permanently attach or removable attach to the rim of the container.
Further variations of integrated, permanent or temporary collars can include a collar channel that seats within the rim closure channel as shown in 7C and particularly described with regard to
The embodiments were chosen and described to best explain the principles of the invention and its practical application to persons who are skilled in the art. As various modifications could be made to the example embodiments described above with reference to the corresponding illustrations, without departing from the scope of the invention, it is intended that all matter contained in the foregoing description and shown in the accompanying drawings shall be interpreted as illustrative rather than limiting. Thus, the breadth and scope of the present invention should not be limited by any of the above-described example embodiments, but should be defined in accordance with the following claims appended hereto and their equivalents. For example, although the collar may be a separate structure from the rim of the can, it will be appreciated that the collar may be formed as a part of the can rim. Generally, according to the spout of the present disclosure, in its retracted position, the spout fits within the can and engages the rim either directly or through a separate collar so that the spout's top edge is proximate to the rim and sits below the lid of the can, whether the lid is friction fit to the original can rim or if it is fit to the top side of the collar and in the spout's extended position, its bottom flange sealingly engages with the bottom side of the rim, either directly or through the separate collar, and the spout's top edge is situated outside the opening of the can.
