Description

CONTAINER FOR COLLATED STRIPS OF FASTENERS

BACKGROUND OF THE INVENTION

1. Field of the Invention

[0001] The present invention relates to improved containers for collated strips of fasteners.

2. Description of the Related Art

[0002] Collated strips of fasteners, e.g., nails, are frequently sold in large boxes containing thousands of identically sized fasteners. These boxes are particularly heavy, are often made of disposable cardboard, and are subject to weathering and deterioration. The use of such boxes is directed primarily toward larger construction projects requiring thousands of identically sized collated fasteners for use in a fastening tool. [0003] In contrast, smaller construction projects may require fewer fasteners. A variety of smaller projects may require different sizes or different types of fasteners. Existing containers for holding and dispensing fasteners useful in smaller projects, such as the one disclosed in U.S. patent application 2005/0072783, are reduced in size and contain far fewer fasteners. Such containers are commonly box shaped and made of plastic. Also, some containers include a lid having a portion that can be locked in an open position.

[0004] Some of these containers utilize internal positioning trays or other spacers to conform to the shape and number of collations to be held. These positioning trays or spacers may vary in number or configuration to enable the same size and shape of container to hold one of a variety of different types and sizes of collated strips of fasteners. Thus, the external dimensions of the container may be significantly greater than the usable interior space. [0005] Retail shelf space and product appearance are important considerations in the design of these containers, as they are displayed for individual consumers. However, many existing containers are bulky, unevenly weighted, difficult to carry, and waste valuable shipping and retail shelf space.

[0006] What is needed is a convenient and easy to use container that is capable of storing a variety of types and sizes of collated strips of fasteners in a number appropriate for smaller construction projects, and which appeals to the consumer while minimizing space requirements for shipping and retail shelf display and/or storage.

BRIEF SUMMARY OF THE INVENTION

[0007] The present invention provides a container particularly useful for shipping, storing, displaying, and using collated strips of fasteners.

[0008] The container may include a receptacle having a floor, a base rim, an open end, a pair of generally parallel side walls, and a pair of end walls. The floor of the receptacle may have a generally rectangular shape, surrounded by the end walls and side walls. The container may have a length of between about 7 1/2 inch and about 8 1/2 inch and a height of between about 2 1/2 inch and about 3 inch. The floor may have base rim extending downward from the floor and integral with the side walls and end walls. The side and end walls may define an open end opposite the floor and may have a gripping flange about the open end for releasably engaging a complementary lid. [0009] The container may also include a removable lid having an elevated cap region, a rotation joint, and clamping and positioning bands. The elevated cap region may be stackably mountable with the base rim of the receptacle. The rotation joint may divide the lid into a openable portion and a fixed portion, the openable portion being pivotable about the rotation joint. The openable portion may also releasably engage the fixed portion to lock in an open position.

[0010] The container may be loaded with a plurality of collated strips of fasteners.

The plurality may include 13 to 17 collated strip of fasteners, each strip having 33 to 38 fasteners and a projected length of between about 7 3/4 inch and about 8 1/4 inch. The loaded collated strips of fasteners may be loaded substantially vertical, side by side, with each consecutive strip in an alternating heads-up, heads-down orientation and angled in directions opposite one another.

[0011] These and other features and advantages are evident from the following description of the present invention, with reference to the accompanying drawings.

[0012] Referring to FIGS. 1 to 4, a container for collated strips of fasteners is shown, having a receptacle 10, and a removable lid 12. The receptacle and removable lid may be made of polypropylene or any other durable, weather resistant plastic. The use of a durable plastic allows the container to be usable over a long period for shipping, storing, displaying and using the fasteners. The receptacle 10 may be substantially transparent or translucent, allowing consumers to observe its contents. The removable lid 12 may be a specific color and include a company logo or other identifiers 14, providing consumer recognition and product reinforcement. A label 16may be placed on an end wall so that when stacked on a shelf, the container does not unnecessarily waste the length of retail shelf space along an aisle.

Receptacle

[0013] Turning to FIGs. 6 and 9, the receptacle may have a generally rectangular floor 20. A base rim 22 may uniformly extend from the floor in a direction normal to the floor. A free edge24 of the base rim may form a generally flat surface for engaging another generally flat surface, i.e., a retail shelf, or the lid of another container, and supporting the container and its contents. The base rim 22 may have a depth of between about 1/8 inch and about 1/2 inch, more preferably between about 3/16 inch and about 5/16 inch, and most preferably about 1/4 inch.

[0014] The floor may be bounded by a pair of generally parallel side walls 30, 32 having a length of between about 8 inches and about 10 inches, more preferably between about 8 1/2 inches and about 9 1/2 inches. The side walls may be separated by a width of between about 2 inches and about 3 inches, more preferably between about 2 1/4 inches and about 2 1/2 inches. The floor may also be bounded by a pair of end walls 34, 36 to create a receptacle having an open end 38. the side walls and end walls may have a height of between about 2 1/2 inches and about 3 inches

[0015] As shown in FIG. 10, the side walls and ends walls may be continuous and joined at rounded corners. The side walls and end walls may also include a slight outward taper from the floor 20 to the open end 38 to provide a wider open end for easier removal of contents within the receptacle. The base rim 22 may be continuous with the side walls and end walls to provide the container with the widest possible support. Because the girth of receptacle is small, the container may easily be held in a user's hands.

[0016] The side walls and end walls the near open end may also include a clamping flange 40 defined by a short outwardly extending lip around the perimeter of the open end. The clamping flange 40 may runs along the entire perimeter of the open end and is normal to and extends outwardly from the side walls 30, 32 and end walls 34, 36. The side walls and end walls may also include a gripping flange 42 below the clamping flange 40 to make the container easier to hold when opening or closing the removable lid. The gripping flange may also block a user from accidentally applying an opening force to the removable lid. The gripping flange 42 may run along the entire perimeter of the open end and is normal to and extends outwardly from the side walls and end walls to an extent greater than the clamping flange 40.

PLURALITY OF COLLATED STRIPS OF FASTENERS

[0017] Turning to FIGs, 6, 7 and 10, a plurality of collated strips 50 of fasteners 52 may include between about 10 to about 20 collated strips of fasteners bound together by a band 54. Each fastener 52 in the collated strips 50 of fasteners may have a length of between about 2 inches and about 3 inches. Each collated strip 50 of fasteners may have between about 30 to about 40 fasteners, each fastener forming an angle A of between about 55 degrees and about 65 degrees with respect to a flat surface 56 when the heads 58 or the tips 60 of the fasteners are all touching the surface 56. Each collated strip of fasteners may have a projected length L of between about 7 1/2 inches and about 8 1/2 inches, and preferably about 8 inches.

[0018] As shown in FIGs. 6 and 7, each collated strip of fasteners may be loaded into the receptacle generally parallel with the side walls. The strips of fasteners may be loaded in abutting, side-by-side condition, with an alternating heads up, heads down orientation, the heads up orientation defined by loading a collated strip of fasteners with the head 58 of each fastener 52 positioned adjacent the open end 38 of the receptacle, the heads down orientation defined by loading a collated strip 50 of fasteners 52 with the head 58 of each fastener 52 positioned adjacent the floor 20 of the receptacle. This configuration maximizes the use of the container's volume while allowing each collated strip of fasteners to be removed form the receptacle without the heads of nearby fasteners on adjacent strips interfering with removal.

[0019] Adjacent collated strips of fasteners may also be angled in directions opposite one another so that the weight of the plurality of collated strips of fasteners is more evenly distributed throughout the receptacle, and so that one end, e.g., 70. 72 of each collated strip of fasteners may be more easily grasped by the user and removed from the receptacle with minimal interference from an adjacent collated strip of fasteners. [0020] The length of the floor and side walls may be between about 100% and about 120%, more preferably between about 105% and about 115%, and most preferably about 110% of the projected length of each collated strip of fasteners.

REMOVABLE LID

[0021] Turning to FIGs. 2, 3 and 8, the removable lid 12 may have a generally flat lid wall 80 and a clamping wall 82. When the removable lid is attached to the receptacle 10, the Hd wall 82 may extend slightly beyond the perimeter of the clamping flange 42 on the receptacle. At this point, the clamping wall 82 may extend downwardly from the lid wall 80 toward the gripping flange 44 and around the outside of the clamping flange 82. Near the gripping flange 44, a gripping rim 84 may extend peripherally outwardly from the clamping wall 82 to receive an opening force. Preferably, the gripping rim 84 is normal to the clamping wall 82 and closely spaced from and parallel to the gripping flange 44. The gripping rim 84 may have one or more corner thumb tabs 86 which extend beyond the gripping flange 44 to further facilitate the application of an opening force. [0022] As seen in FIG. 9, the removable lid has an interior surface 80a facing the receptacle when the removable lid is attached to the receptacle. The interior surface 80a of the lid wall may have a number of positioning bands 90 extending downwardly from the surface 80a, normal to the surface 80a. When the removable Kd is attached to the receptacle, the positioning bands 90 penetrate the open end of the receptacle and frictionally engage inside surfaces 30a, 32a of the side walls 30, 32 to resist removal of the Hd. Similarly, clamping bands 92 may extend inwardly from the inside surface of the clamping wall 82, normal to the clamping wall 82. When the removable Hd is attached to the receptacle, the clamping bands 92 snap and engage the clamping flange 82, and form an interference fit to resist the removal of Hd.

[0023] The removable Hd 12 may have an openable portion 12a and a fixed portion 12b separated by a rotation joint 95. The rotation joint may be formed by a decrease in the Hd wall thickness. The rotation joint 95 allows a user to rotatably open the openable portion by applying an opening force to the thumb tab 86 and gripping rim 84 on the openable portion. When an opening force is applied to the openable portion, the clamping bands 90 and positioning bands 92 on the openable portion 12a disengage the clamping flange 42, allowing the openable portion to rotatably open about the rotation joint 95, while the clamping bands 90 and positioning bands 92 on the fixed portion 12b remain engaged. To facilitate this action, the the clamping bands 90 and positioning bands 92 on the fixed portion 12b may be collectively longer than the clamping bands 90 and positioning bands 92 on the openable portionl2a. The rotation joint may run along the entire length of the removable lid 12 to allow the user to withdraw contents that occupy substantially the entire length of the receptacle 10.

[0024] As also seen in FIGs. 1, 6 and 9, the removable lid 12 may also have an elevated cap region 96 stackably mountable with the base rim 22on a receptacle. The elevated cap region 96 may extend above the wall 80 to a height of between about 1/8 inch and about 3/8 inch, more preferably between about 3/16 inch and about 5/16 inch, and in the illustrated embodiment, about 1/4 inch. When stackably mounted to the elevated cap region 96, the base rim 22 may extend downwardly around the elevated cap region with the flat surface 24 contacting the lid wall 80. In the stacked position, there may be a maximum lateral tolerance between the base rim and the elevated cap region of between about 0 inch and about 1/8 inch.

[0025] The elevated cap region 96 on the fixed portion 12b may also include a recessed channel 98 bounded by walls 91, 93 and running along the rotation joint, allowing the openable portion 12a to rotate about the rotation joint 95 without the elevated cap region 96 on the openable portion 12a without colliding with the elevated cap region 96 on the fixed portion 12b. The elevated cap region 96 on the openable portion 12a may have spaced apart recessed wall portions 97, 99 located to interfit with the channel 98 on the openable portion 12a to further facilitate rotation of the openable portion and to releasably lock with the channel 98 on the fixed portion 12b to hold the lid in the open position. When the openable portion 12a of the lid is rotated toward the fixed portion 12b to an angle of about 90 degrees, the openable portion of the lid releasably locks in the open position. [0026] With the lid in the open position, a user may easily remove or insert a collated strip of fasteners. Furthermore, when the Hd is open, the container loaded with a plurality of collated strips of fasteners may be tipped or turned upside down to remove a collated strip of fasteners without the removable lid detaching from the receptacle. [0027] ' While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific exemplary embodiment herein. The invention should therefore not be limited by the above described embodiment, but by all embodiments within the scope and spirit of the invention as claimed.
