Abstract
A product in the form of a segmented strip includes tabs to assist in dispensing individual segments from the strip. Segments of the strip are separated by lines of perforations running transverse to the strip. A tab of sufficient size to be easily grasped is adhesively secured to the strip across the line of perforations. The tab is positioned so that less than half of the area of the tab is disposed on the segment that is the first to be dispensed. The majority of the surface of the tab is disposed on a segment that will be subsequently dispensed. When the first segment is dispensed, the tab is retained on the next segment since the adhered surface on the next segment is greater. The exposed portion of the tab may then be readily located and grasped when the next segment is to be dispensed.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to the field of product packaging. More specifically, the invention relates to a pull-tab to assist in dispensing a product comprising a segment of an elongated strip, which may be packaged in a roll.
2. Background
Conventional self-adhesive bandages are typically packaged individually in a paper wrapper. Frequently, it is difficult to remove the bandage from the paper wrapper, remove the release liner from the adhesive and apply the bandage, especially in urgent care situations. A roll dispenser for self-adhesive bandages has been proposed to make the process of dispensing and applying a bandage more convenient. An example of such a dispenser is shown and described in U.S. Pat. No. 5,782,786.
A problem with adhesive bandages dispensed from a roll, which is a problem shared by many other products dispensed in a similar manner, is locating and grasping the end of the roll in order to dispense the next bandage. Typically, the consumer must feel around the circumference of the roll to locate the end of the roll and then lift the end with a fingernail. Various tab arrangements have been proposed in a context of other products to facilitate finding and lifting the end of a rolled adhesive product. Such arrangements are shown, for example, in U.S. Pat. Nos. 4,512,462; 4,727,616 and 6,014,788.
SUMMARY OF THE INVENTION
The present invention provides an improved tab to assist in dispensing a product from a segmented strip of such products. Segments of the strip are separated by lines of perforations running transverse to the strip. A tab of sufficient size to be easily grasped is adhesively secured to the strip across the line of perforations. The tab is positioned so that less than half of the area of the tab is disposed on the segment that is the first to be dispensed. The majority of the surface of the tab is disposed on a segment that will be subsequently dispensed. When the first segment is dispensed, the tab is retained on the next segment since the adhered surface on the next segment is greater. The exposed portion of the tab may then be readily located and grasped when the next segment is to be dispensed.

DETAILED DESCRIPTION
In the following description, for purposes of explanation and not limitation, specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known methods and devices are omitted so as to not obscure the description of the present invention with unnecessary detail.
FIG. 1
illustrates a roll
10
of adhesive bandages. Although the present invention is described in the context of an adhesive bandage product, it is to be understood that the invention may be applied to any product comprising segments of an elongated strip. Some examples of such products include adhesive tape, postage stamps, mailing labels, etc. As shown in
FIG. 1
, a first adhesive bandage
12
having an absorbent pad
24
has been partially detached from roll
10
. This is facilitated by the use of tab
14
. Bandage
12
is connected to a next bandage
16
on the roll. Bandages
12
and
16
are separated by a line of perforations
18
. Tab
20
is adhesively secured to bandages
12
and
16
straddling the line of perforations. Less than half of the surface of tab
20
is disposed on bandage
12
, whereas the majority of the surface of tab
20
is disposed on bandage
16
. As bandage
12
is removed from roll
10
by separating at the line of perforations
18
, tab
20
is retained on bandage
16
due to the fact that the surface area adhered to bandage
16
is greater than the surface area adhered to bandage
12
. Once bandage
12
is removed, tab
20
will be exposed at the end of roll
10
to assist in dispensing bandage
16
.
FIG. 2
is a plan view of bandage
12
subsequent to its removal from roll
10
. Bandage
12
is similar to a conventional adhesive bandage, having an adhesive surface
22
and an absorbent pad
24
. Tab
14
, which is secured to the adhesive surface of bandage
12
may be removed and discarded at the time the bandage is applied. If desired, the tab may be left in place to assist in removing the bandage from the skin.
FIG. 3
illustrates a method of manufacturing a segmented product with tabs in accordance with the present invention. Material for producing the segmented product is provided in bulk on roll
30
. The material comprises a first material
32
having a second material
34
adhesively attached thereto. In the case of an adhesive bandage product, first material
32
would comprise the adhesive tape substrate for the bandage, which is typically a plastic film. Material
34
, which will be processed to form the tabs of the present invention, is typically provided as a paper or plastic release liner for the adhesive surface of material
32
.
Material drawn from roll
30
passes across cutter
40
, which perforates the layer of material
32
. The perforations do not extend into the layer of material
34
. Next, cutter
42
die cuts the shape of the tabs into the layer of material
34
. Here again, the depth of the cut is controlled so as not to extend into the layer of material
32
. Cutters
40
and
42
are synchronized so that the tabs will be properly registered with the lines of perforations. After exiting cutter
42
, the excess portion of the layer of material
34
is removed from material
32
and wound onto waste material take-up roll
44
, leaving only the tabs adhered to material
32
. The processed material is then wound onto take-up roll
50
, which may constitute the final product or which may then be subjected to further processing. In the case of adhesive bandages, absorbent pads are applied to each segment of the processed material. This may be done at any convenient stage of the manufacturing process. Moreover, it should be noted that the sequence of cutting the perforations and the tabs is not critical. Hence, the tab cutting operation may be performed prior to the perforating operation, if desired.
FIG. 4
is a plan view of the layer of material
32
at location A in
FIG. 3
after exiting cutter
40
. Lines of perforations
52
extend transversely across the strip of material defining the product segments. Cutter
40
may also create notches
54
at the edges of the strip to further facilitate separation of the segments.
FIG. 5
is a plan view of the layer of material
34
at location B in
FIG. 3
after exiting cutter
42
. Tabs
56
have been die cut into the layer of material in registration with the lines of perforations
52
. Tabs
56
may be round, oval, rectangular, or any other convenient shape. Only the tabs
56
remain on layer of material
32
after the excess of material
34
is removed (as shown in FIG.
3
).
It will be recognized that the above-described invention may be embodied in other specific forms without departing from the spirit or essential characteristics of the disclosure. Thus, it is understood that the invention is not to be limited by the foregoing illustrative details, but rather is to be defined by the appended claims.
