Description

FIELD OF THE INVENTION

This invention is related to an apparatus for opening a container, mixing contents in a container, and for cleaning a container. More particularly, this invention is related to an apparatus that can open a container, mix and clean out contents in a container in a single tool.

BACKGROUND OF THE INVENTION

Many tools are used in finishing dry wall architecture. Typically, a container or bucket, containing dry wall plaster materials to be applied to surfaces such as walls, needs to be opened, mixed and cleaned out. In the past, multiple tools have been used to handle these tasks. However, producing separate tools for each task may not be cost effective, and also presents inconveniences due to the multiple tools needed for handling and manipulation. Further, cleaning out buckets containing dry wall materials using scraping tools having a conventional flat shape causes overly repetitive scraping of the sides. In addition, such scraping tools can require inconvenient manipulation of the tool and cumbersome situating of the bucket in accessible positions, such as tilting, turning, etc., so that the scraping tool can reach the sides of the bucket.

Therefore, there is a need for an improved device that can more efficiently and easily scrape a container of its contents such as plaster material for dry wall finishing, and that also can open the container and mix the contents of the container in one tool.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

In the following description of the illustrated embodiments, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration of the embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized as structural changes may be made without departing from the spirit and scope of the present invention.

FIG. 1 illustrates one preferred embodiment of an apparatus 10 that opens a container, mixes contents contained in the container, and cleans out the container. The apparatus 10 includes an elongated member 60 having a first end 20 and a second end 40. The first end 20 includes an opener head 22. The opener head 20 is used for opening a container such as but not limited to a bucket. Preferably, the apparatus 10 is used for opening, mixing, and cleaning out five gallon buckets. Preferably, the five gallon buckets or containers are conventional buckets used for holding materials such as but not limited to plasterboard and drywall products, and also, paint and driveway sealer products. The elongated member 60 may have a length suitable for reaching the bottom of a container such as the five-gallon buckets. Preferably, the elongated member 60 has a length so that the opener head 22 does not enter the container, and does not contact any of the contents in the container. An opening 67 may be disposed along the elongated member 60 for providing a structure so that the apparatus 10 can be stored, such as for hanging on a wall or the like. The opener head 22 may have a longitudinal portion 27 with outwardly extending portions 26, 28 that extend from a side of the first end 20 in the same direction as and parallel to each other. Hook members 24 associated on the portions 26 and 28 provide means for prying open a container such as by engaging a lip of a resealable cover of the container or bucket. The apparatus 10, using the opener head 22, may be worked along the lip of the resealable cover so as to open the container. FIG. 1 shows an exemplary opener head 22 in which the opener head 22 resembles a C-shape opener head. However, it should be appreciated that another suitable opener head may be employed to achieve the same opening function.

The second end 40 includes a tool support member 43 having a first end 44 and a second end 42 and two oppositely disposed sides 47 and 49. Support members 46 extend longitudinally from the elongated member and connect with the tool support member 43 to provide structural support of the second end 40 and tool support member 43. Preferably, the side 47 is formed of a substantially smooth surface preventing obstruction therealong. The tool support member 43 includes a sharpened edge 41, such as a beveled edge or slanted tip at the second end 42. The sharpened edge 41 may be disposed along a width 30 of the tool support member 43. The sharpened edge 41 allows the apparatus 10 to scrape the sides of a container so as to clean the container of its contents.

At least one cut out 45 is disposed on the tool support member 43 between the first end 44 and the second end 42. The cut outs 45 are defined as openings through the tool support member 43, through the first side 47 and the second side 49 (shown in FIGS. 2-3). For mixing purposes such as mixing plasterboard or dry wall materials, the cut outs 45 allow flow of the contents in the container through the tool support member 43. The number of cut out regions 45 illustrated in FIG. 1 is four. However, the number of cut outs illustrated is merely exemplary as more or less cut out regions may be employed as suitable and required when using the apparatus 10 for mixing. Preferably, the tool support member 43 is flat in shape.

Further illustrated in FIG. 1, the elongated member 60 of the apparatus 10 preferably is constructed and arranged with oppositely disposed support structures 61, 63 that protrude from sides of the elongated member 60. As best shown in FIG. 8A, the support structures 61, 63 protrude in a direction transverse to the longitudinal direction of the elongated member 60, and extend along the length of the elongated member 60. Preferably, the support structures 61, 63 have the same width, and both may have a width larger along the elongated member 60 proximate the opener head 22 than along the elongated member 60 proximate the tool support member 43.

Further, a bridging portion 65 may be formed between the support structures 61, 63 providing further strength for the apparatus 10. As shown in FIG. 1, only one bridging portion 65 connects the support structures 61, 63 at a middle of the elongated member 60. It will be appreciated that more than one bridging portion may be formed along the elongated member 60 as needed to provide suitable strength. The support structures 61, 63 form and resemble an I shaped beam (FIG. 8A) along the length of the elongated member 60, and provides the apparatus 10 with improved strength, while maintaining a lightweight tool where a minimum amount of material is needed for its construction. Particularly, the support structures 61, 63 and bridging portion 65 can provide handle strength and support for the elongated member 60 when gripping during use, such as in the opening of a container.

Further, the second end 20 having the opener head 22 also defines oppositely disposed support structures 21, 23 that protrude from sides of the opener head 22. As best shown in FIG. 8B, the support structures 21, 23 protrude at least from the longitudinal portion 27 and the portion 28 in a direction transverse to the direction the portions 27, 28 extend. At least one bridging portion 25 may be formed between the support structures 21, 23 to provide support and strength in the opener head 22. It will appreciated that as many bridging portions may be formed as needed to provide suitable strength and support. A protrusion 29 extends outward in the same direction as and between the portions 26, 28 on the opener head 22 and along the longitudinal portion 27. The protrusion 29 provides further support and strength of the opener head 22. The support structures 21, 23 (FIG. 8B) also form and resemble an I shape configuration similar to support structures 61, 63 on the elongated member, and provide the opener head 22 with improved strength, while maintaining a lightweight tool where a minimum amount of material is needed for its construction. More preferably, the support structure 21 can define a width D that is smaller than the width of the support structure 23 (A in FIGS. 2, 3) further minimizing the amount of material used while still providing suitable strength to the opener head 22. The bridging portions 25 provide increased strength and durability in the opener head 22, such as at points of stress when the apparatus 10 is being used to open a container.

FIGS. 2 and 3 illustrate side views of the apparatus 10. Similar features that have been described in FIG. 1 are not further detailed here. The tool support member 43 is shown in section in FIG. 2. Further illustrated in FIGS. 2 and 3, a first width A is defined along the opener head 22, and preferably corresponds with the width of the support structure 23. A second width B is defined along the elongated member 60 and extends from about a middle of the elongated member toward the first end 20 proximate the opener head 22. A third width C is defined along the elongated member 60 and extends from about the middle of the elongated member toward the second end 40 proximate the tool support member 43. This configuration provides the apparatus 10 having a larger width at the opener head 22 for added strength and durability toward the end 20 at the opener head 22. Preferably, the apparatus 10 is gripped or handled toward the opener head 22 when using the apparatus 10 for opening a container. It will be appreciated that the apparatus 10 along the elongated member 60 and opener head 22 may be other width configurations and arrangements, such as being one uniform width, so long that the strength and durability are not compromised.

In another preferred embodiment, a sharpened edge 41 may be shaped as a radial curvature 70. FIGS. 4a and 4b illustrate examples of the front end view of a sharpened edge 41a, 41b with a radial curvature 70a, 70b, respectively. In FIG. 4a, the radial curvature 70a is provided to allow scraping of a sidewall of a container, such as exemplary container 100, so as to clean the container 100 of its contents. The radial curvature 70a of the sharpened edge 41a substantially corresponds with the sidewall of the container 100 such that the sharpened edge 41a is contactable with the sidewall of the container 100. Preferably, the radial curvature 70a corresponds to a 6.0 inch radius that is the curvature of a 6.0 inch radiused container. In FIG. 4b, the radial curvature 70b is illustrated as being at least on one side 47b of the sharpened edge 41b. The other side 49b is shown as a substantially flat surface. As depicted in FIG. 4b, the radial curvature 70b would have a cross-sectional size increasing towards a middle portion 90b of the sharpened edge 41b. Such a structure can provide an apparatus with additional strength and durability at the second end. It will be appreciated that the side 49b also may be other surfaces such as bulged, bumped or uneven surfaces, as long as it does not interfere with the structure of the sharpened edge 41b at side 47b from contacting a container sidewall.

FIG. 5 illustrates the apparatus 10a in contact with the sidewall of the container 100 and the arrow indicates a preferred scraping motion for scraping the sidewall. As the sharpened edge 41a having the radial curvature 70a contours the sidewall of the container, the apparatus 10a easily reaches and contacts the sidewall of the container 100. As the sharpened edge 41a, with the radial curvature 70a, contours the sidewall of the container, the need to manipulate the position of the container, such as by tilting or turning, can be significantly reduced making scraping less cumbersome and difficult. Furthermore, the radial curvature 70a of the sharpened edge 41a eliminates excessive scraping motions, otherwise required by flat bladed scraping tools, making it easier and more efficient in scraping the container 100. It will be appreciated that the sharpened edge 41b may also be used in the same manner as sharpened edge 41a.

It will be appreciated that the apparatus may be integrally formed of one tool. Also, the apparatus may be integrally molded of a plastic material, such as by injection molding. Preferably, the apparatus is a chemically resistant plastic material, such as polypropylene. It will be appreciated that other suitable plastic materials may be employed for the apparatus. Furthermore, the apparatus can be used on containers holding materials such as but not limited to plasterboard and drywall products, and also paint, and driveway sealer products. Preferably the containers are conventional five gallon containers or buckets that typically hold these products. Preferably, the five gallon buckets define a curvature where the bucket radius is about 6 inches.

FIG. 6 outlines another preferred embodiment of a method for removing contents from a container that includes providing an apparatus as previously described 200. Preferably, the apparatus is used on a bucket or container containing dry wall materials. The container is opened using the opener head 202a. The contents of the container are mixed 204 by stirring the contents using the apparatus where the cut outs allow flow through the tool support member during mixing. The container may be emptied and the sharpened edge including its radial curvature allows for downward scraping 206 of the container so as to clean out the container of its contents. FIG. 7 illustrates using the opener head of an apparatus 10a for opening a container 202b having an alternative cover. It will be appreciated that the apparatus 10a has features similar to apparatus 10.

As described above, the present invention provides the advantage of an apparatus being able to open a container, mix the contents contained within the container, and scrape the container clean of its contents. The invention provides the above features in one tool that is both convenient to use and cost effective. Further, the radial curvature in the sharpened edge allows for the apparatus to thoroughly and efficiently clean out the container of its contents by contouring the sidewall of the container allowing the apparatus to scrape along the sidewall.

The above specification, examples and data provide a complete description of the manufacture and use of the composition of the invention. Since many embodiments of the invention can be made without departing from the spirit and scope of the invention, the invention resides in the claims hereinafter appended.
