Description
CA 02207249 1997-0~7-28 CONTAINER DUST SEAL
BACKGROUND OF T~E INVENTION
The present invention relates to sealing devices for containers, and more particularly to sealing devices preventing interior contamination of containers during handling of the containers.
Shippers o~ sensitive electronics and computer equipment strive to assure that dust and other contaminates do not enter the interior of containers used to package the equipment for shipment and storage. This dust can cause subsequent equipment failure.
These shippers typically use containers, such as corrugated boxes, that have handle or cont~; ner openings into which the shippers can insert their fingers to grasp and to li~t the containers. Often the handle openings simply consist of slits in the containers, which the shippers force apart to form the handle openings as they insert their fingers. Unfortunately, dust and other cont~m;n~tes can enter the interior of the containers along with the shippers' fingers or after the shippers have formed the handle openings.
The shippers have attempted to m; n; m; ze this contamination by inserting separate sheets of material, such as corrugated cardboard, between the handle openings and the packaged equipment. However, this method has several disadvantages. First, the separate sheets provide limited reliability against contamination of the packaged equipment. Further, the separate sheets increase the cost of the container.
CA 02207249 1997-0~-28 SUMMARY OF THE lNv~N~l~loN
The a~orementioned problems are overcome in the present invention comprislng a dust seal adhesively mounted on the inside of the container over the handle opening to prevent dust ~rom entering the container through the handle opening.
More specifically, the dust seal preferably includes a dust-tight finger mitten that is hermetically sealed about the handle opening o~ the cont~; ner. Shippers who insert their ~ingers through the handle openings to li~t the container, pa~ their fingers into the dust-tight finger mitten, which along with the hermetic seal prevents dust from entering the interior of the container.
In one embodiment, the dust seal has a top film that is sealed to a base ~ilm in laminated arrangement. The base ~ilm has an opening so that fingers can pass through the base film. The base film is sealed to the container to align the opening means of the base film with the handle opening. The top film does not have an opening and therefore prevents the ingress of dust and dirt into the container. The base and top f ilms together define the mitten.
In another embodiment, the dust seal contains a top film that is laminated to a base film using an adhesive between the films in the perimeter zones of the films to form a dust-tight seal. The base film has an interior slit to allow fingers to pass through the base film. The base film is sealed to the container to form a dust-tight seal using an adhesive located between the CA 02207249 1997-0~-28 container and the base film in an inner zone surrounding the slit, so that the slit is aligned with the handle opening. The top film is unper~orated. Shipper~ can insert their ~ingers through the handle opening and the base film to li~t the container. The seals and ~ilms prevent dust from entering the interior of the container and contaminating the packaged goods.
The dust seal of the present invention permits shippers to insert their ~ingers into the handle opening to lift the container; yet, the dust seal reliably prevents dust and other contaminates from entering the interior o~ the container through the handle opening. The dust seal costs less than the use of an additional sheet of material to attempt to seal the handle opening or block dust ~rom entering the container interior, and is more reliable.
These and other ob~ects, advantages, and features of the invention will be more readily understood and appreciated by re~erence to the detailed description of the preferred embodiment and the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The dust seal of the present invention is illustrated in the drawings and generally designated 20. The dust seal is shown in Fig. 1 sealed to the interior 24 o~ wall 22 o~ container 26.
In the preferred embodiment, container 26 is a folded corrugated box having a floor 21, a pair of side walls 23, and a pair o~ opposite end walls 22. While a corrugated container is illustrated, the dust seal o~ the present invention i~ equally applicable to containers and other packaging having access openings through the container 37. As used herein, "interior of the container" means the interior volume or space of the container 26.
A handle opening 37 is die-cut or otherwise formed in each o~ the end walls 24. As used herein, "handle opening"
includes, but is not limited to, any structure or technique permitting fingers or a device to be inserted into a portion o~ the container to lift or otherwise move the container 26. "Handle opening" includes a hole or other opening in wall 22, as well as per~orations or slits in wall 22 that can be pushed open when ~ingers are inserted.
Turning to Figs. 2-5, the dust seal 20 includes a top sheet or film 28 and a base sheet or film 29 made of a material that is impervious to dust. As used herein, "dust" has a broad meaning and encompasses dust, dirt, liquids, and other contaminates, particularly those that may damage electronics and computer e~uipment or other sensitive contents. Preferably, the top and base sheets or films are made of plastic sheets of material, such as polyethylene, poly~ropylene, polystyrene, polyester, and combinations thereof. However, other materials impervious to dust can be used, such as paper. Top ~ilm 28 and base film 29 preferably are of the same size and shape and are overlyingly aligned with one another. Each has a perimeter zone 30 that encircles the perimeter of the film (Fig. 4).
I'he top ~ilm 28 is securely sealed to the base film 29 in laminated arrangement. One means to secure or seal top film 28 to base film 29 is to locate an adhesive 32 between top film 28 and base ~ilm 29 in the corresponding or aligned perimeter zones 30 of the top and base films. Suitable adhesives are pressure-sensitive adhesives or other adhesives, as are known in the art. Other means of sealing the top film to the base film include heat sealing, stapling, or other means of physically attaching the ~ilms together. Preferably, the top and base films are sealed to form a "dust-tight" seal, that is, a seal that does not allow dust to pass between the top and base ~ilms. Such a seal typically will be substantially continuous around the entire periphery of the lamination. More preferablyl the means of 8ealing top film 28 to base film 29 forms a hermetic or air-tight seal.
CA 02207249 1997-0~-28 Base film 29 includes an opening 33, which permits one or more ~ingers 36 to pass through the base film (Fig. 3). In the preferred embodiment, the opening 33 is one or more slits 34 in the base film 29. As seen in Fig. 4, the slit 34 includes at longitudinal slit 34a and transverse slits 34b along the longitudinal slits. The opening also could be a hole, per~orations, or a relatively weak area so that one can easily push a finger through the base film. Base ~ilm 29 contains an inner or intermediate zone 40 surrounding the opening 33 (Fig. 4).
The base film 29 includes an adhesive 38 on the side of the base ~ilm that will face the box wall 22. The adhesive forms a continuous ring (race-track shaped as shown in Fig. 4) in the intermediate zone 40 surrounding the opening 33. Suitable adhesives and alternative securing or sealing means are the same as those used ~or the means o~ sealing top film 28 to base ~ilm 29, as discussed above.
Referring to Fiy. 3, top film 28 and base film 29, together with the adhesive 32 form finger mitten 42. Finger mitten 42 is a mitten, pouch, or balloon that surrounds one or more fingers 36 as they are inserted through the handle opening. The laminated construction of the dust seal 20 permits the finger mitten 42 to lay ~lat against interior wall 24 be~ore the fingers 36 are inserted into the ~inger mitten 42.
CA 02207249 1997-0~-28 -Manufacture and Use The dust seal 20 i8 manu~actured including conventional techniques, particularly from the label manufacturing art~.
Although not shown in the drawings, each dust seal ig mounted on a release liner, or multiple du~t seals are mounted on a single or continuous release liner, during manufacture. The release liner protects the adhesive 38 until the dust seal 20 is applied to the container.
The dust seal 20 is applied to the interior of the cont~;ner 22 with the adhesive 38 engaging and adhering to the wall 24. The dust seal is aligned with and covers the entire handle opening 37, and the adhesive 38 surrounds the handle opening.
"Aligned with" as used herein means that the opening 33 o~ the finger mitten 42 is aligned with the handle opening 37 so that a ~inger can be inserted into ~inger mitten 42 without cnmmlln~cating with or entering into the interior of the container. Preferably, the dust seal forms a "dust-tight" seal to prevent dust from passing between the base film and the wall. As noted above, and most preferably, the seal is a hermetic or air-tight seal. When the dust seal 20 is properly mounted, the finger mitten 42 is sealed about handle opening 37.
To lift the container 26 having the dust seal 20, a lifter inserts one or more fingers 36 through handle opening 37 and opening 33 into the finger mitten 42. The lifter forms a finger grip about wall 22 to lift container 26. Since finger mitten 42 is made of material impervious to dust and is sealed to wall 22 with a dust-tight seal, dust cannot enter the container interior through handle opening 37.
The above description is that of a preferred embodiment o~ the invention. Various alterations and changes can be made without departing ~rom the spirit and broader aspects o~ the invention as defined in the claims, which are to be interpreted in accordance with the principles o~ patent law, including the doctrine of e~uivalents.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The dust seal of the present invention is illustrated in the drawings and generally designated 20. The dust seal is shown in Fig. 1 sealed to the interior 24 o~ wall 22 o~ container 26.
In the preferred embodiment, container 26 is a folded corrugated box having a floor 21, a pair of side walls 23, and a pair o~ opposite end walls 22. While a corrugated container is illustrated, the dust seal o~ the present invention i~ equally applicable to containers and other packaging having access openings through the container 37. As used herein, "interior of the container" means the interior volume or space of the container 26.
A handle opening 37 is die-cut or otherwise formed in each o~ the end walls 24. As used herein, "handle opening"
includes, but is not limited to, any structure or technique permitting fingers or a device to be inserted into a portion o~ the container to lift or otherwise move the container 26. "Handle opening" includes a hole or other opening in wall 22, as well as per~orations or slits in wall 22 that can be pushed open when ~ingers are inserted.
Turning to Figs. 2-5, the dust seal 20 includes a top sheet or film 28 and a base sheet or film 29 made of a material that is impervious to dust. As used herein, "dust" has a broad meaning and encompasses dust, dirt, liquids, and other contaminates, particularly those that may damage electronics and computer e~uipment or other sensitive contents. Preferably, the top and base sheets or films are made of plastic sheets of material, such as polyethylene, poly~ropylene, polystyrene, polyester, and combinations thereof. However, other materials impervious to dust can be used, such as paper. Top ~ilm 28 and base film 29 preferably are of the same size and shape and are overlyingly aligned with one another. Each has a perimeter zone 30 that encircles the perimeter of the film (Fig. 4).
I'he top ~ilm 28 is securely sealed to the base film 29 in laminated arrangement. One means to secure or seal top film 28 to base film 29 is to locate an adhesive 32 between top film 28 and base ~ilm 29 in the corresponding or aligned perimeter zones 30 of the top and base films. Suitable adhesives are pressure-sensitive adhesives or other adhesives, as are known in the art. Other means of sealing the top film to the base film include heat sealing, stapling, or other means of physically attaching the ~ilms together. Preferably, the top and base films are sealed to form a "dust-tight" seal, that is, a seal that does not allow dust to pass between the top and base ~ilms. Such a seal typically will be substantially continuous around the entire periphery of the lamination. More preferablyl the means of 8ealing top film 28 to base film 29 forms a hermetic or air-tight seal.
CA 02207249 1997-0~-28 Base film 29 includes an opening 33, which permits one or more ~ingers 36 to pass through the base film (Fig. 3). In the preferred embodiment, the opening 33 is one or more slits 34 in the base film 29. As seen in Fig. 4, the slit 34 includes at longitudinal slit 34a and transverse slits 34b along the longitudinal slits. The opening also could be a hole, per~orations, or a relatively weak area so that one can easily push a finger through the base film. Base ~ilm 29 contains an inner or intermediate zone 40 surrounding the opening 33 (Fig. 4).
The base film 29 includes an adhesive 38 on the side of the base ~ilm that will face the box wall 22. The adhesive forms a continuous ring (race-track shaped as shown in Fig. 4) in the intermediate zone 40 surrounding the opening 33. Suitable adhesives and alternative securing or sealing means are the same as those used ~or the means o~ sealing top film 28 to base ~ilm 29, as discussed above.
Referring to Fiy. 3, top film 28 and base film 29, together with the adhesive 32 form finger mitten 42. Finger mitten 42 is a mitten, pouch, or balloon that surrounds one or more fingers 36 as they are inserted through the handle opening. The laminated construction of the dust seal 20 permits the finger mitten 42 to lay ~lat against interior wall 24 be~ore the fingers 36 are inserted into the ~inger mitten 42.
CA 02207249 1997-0~-28 -Manufacture and Use The dust seal 20 i8 manu~actured including conventional techniques, particularly from the label manufacturing art~.
Although not shown in the drawings, each dust seal ig mounted on a release liner, or multiple du~t seals are mounted on a single or continuous release liner, during manufacture. The release liner protects the adhesive 38 until the dust seal 20 is applied to the container.
The dust seal 20 is applied to the interior of the cont~;ner 22 with the adhesive 38 engaging and adhering to the wall 24. The dust seal is aligned with and covers the entire handle opening 37, and the adhesive 38 surrounds the handle opening.
"Aligned with" as used herein means that the opening 33 o~ the finger mitten 42 is aligned with the handle opening 37 so that a ~inger can be inserted into ~inger mitten 42 without cnmmlln~cating with or entering into the interior of the container. Preferably, the dust seal forms a "dust-tight" seal to prevent dust from passing between the base film and the wall. As noted above, and most preferably, the seal is a hermetic or air-tight seal. When the dust seal 20 is properly mounted, the finger mitten 42 is sealed about handle opening 37.
To lift the container 26 having the dust seal 20, a lifter inserts one or more fingers 36 through handle opening 37 and opening 33 into the finger mitten 42. The lifter forms a finger grip about wall 22 to lift container 26. Since finger mitten 42 is made of material impervious to dust and is sealed to wall 22 with a dust-tight seal, dust cannot enter the container interior through handle opening 37.
The above description is that of a preferred embodiment o~ the invention. Various alterations and changes can be made without departing ~rom the spirit and broader aspects o~ the invention as defined in the claims, which are to be interpreted in accordance with the principles o~ patent law, including the doctrine of e~uivalents.
