Description
BACKGROUND OF THE INVENTION
[0001] I. Field of the Invention
[0002] The present invention relates generally to adhesive rollers
and, more particularly, to such a roller used for detritus
removal.
[0003] II. Description of the Prior Art
[0004] Lint rollers have long been known and widely used for
removing detritus, such as pet hair, dandruff, lint and the like
from clothing, furniture, etc. These previously known lint rollers
typically comprise a handle having a tubular and cylindrical tape
roll rotatably mounted to the handle.
[0005] Many previously known adhesive rolls for detritus removal
consist of a continuous strip having a backing and with an adhesive
provided on one side of the backing. The strip is wound into a
tubular cylindrical roll so that the strip overlaps itself to form
multiple layers. As the adhesive becomes depleted from use, a
portion of the strip is torn away from the roll to expose fresh
adhesive. This process continues until the entire roll has been
depleted at which time a new roll is mounted onto the handle.
[0006] One disadvantage of the previously known lint rollers having
a continuous strip is that it is very difficult, if not altogether
impossible, for the user to accurately remove a portion of the used
strip equal to substantially one revolution of the adhesive roll.
Removal of more than one revolution of the strip from the adhesive
roll results in waste of the adhesive roll since the excess strip
removed is never used. Conversely, the removal of a strip
substantially less than one full revolution of the adhesive roll
results in used adhesive being left on the roll after the portion
of the strip has been removed. The used adhesive, if a significant
portion of the exposed area of the roll, results in unsatisfactory
detritus removal for the adhesive roll.
[0007] In order to provide a more uniform removal of a portion of
the strip amounting to one revolution of the adhesive roll, it has
been previously known to provide perforations extending laterally
across the strip at spaced intervals along the adhesive strip
corresponding substantially to one full revolution of the adhesive
roll. In the previously known adhesive rolls, the perforations
extend substantially perpendicularly outwardly from one side of the
strip and to the opposite side of the strip.
[0008] These previously known adhesive rolls with laterally
extending perforations extending perpendicularly from one side of
the strip to the other strip have not proven wholly satisfactory in
use. A primary disadvantage of this type of previously known
adhesive roll is that the used sheet from the strip would
oftentimes tear as the sheet was removed from the adhesive roll
because a stress point would be imposed upon the sheet during
removal. Furthermore, whenever the used sheet would tear during
removal, it was necessary for the user to laboriously peel off
shreds of the used sheet which remained on the adhesive roll. Even
after peeling off the shreds of the used sheet from the adhesive
roll, oftentimes debris from the torn used sheet would
disadvantageously remain on the adhesive roll.
SUMMARY OF THE PRESENT INVENTION
[0009] The present invention provides an adhesive roll construction
which overcomes all of the above-mentioned disadvantages of the
previously known devices.
[0010] In brief, the adhesive roll construction of the present
invention comprises an elongated strip having a backing layer and
an adhesive layer overlying one side of the backing layer. The
strip has a first end, a second end and two spaced apart and
substantially parallel sides. Furthermore, the strip is wound from
its first end and to its second end into a tubular cylindrical roll
in which multiple layers of the strip overlap each other.
[0011] At least one elongated perforation, which may be a
continuous slit, is formed in the roll so that the perforation
extends through the multiple layers of the strip. Unlike the
previously known adhesive roller constructions, however, this
perforation extends diagonally from a position spaced inwardly from
at least one side of the strip and to a position spaced inwardly
from the opposite side of the strip. Optionally, the perforation
extends entirely through to one or both sides of the strip. The
diagonal perforation thus minimizes or altogether eliminates stress
on the strip when a used sheet from the roll is torn from the roll
to expose fresh adhesive.
[0012] Optionally, the adhesive roller construction includes a
tubular cylindrical roller support around which the strip is wound.
Preferably, this roller support is made of cardboard.
BRIEF DESCRIPTION OF THE DRAWING
[0013] A better understanding of the present invention will be had
upon reference to the following detailed description, when read in
conjunction with the accompanying drawing, wherein like reference
characters refer to like parts throughout the several views, and in
which:
[0014] FIG. 1 is a side view illustrating a preferred embodiment of
the present invention;
[0015] FIG. 2 is a cross-sectional view taken substantially along
line 2-2 in FIG. 1;
[0016] FIG. 3 is a fragmentary sectional view showing a portion of
the preferred embodiment of the present invention; and
[0017] FIG. 4 is a view illustrating the operation of the preferred
embodiment of the present invention.
DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE PRESENT
INVENTION
[0018] With reference first to FIGS. 1-3, a preferred embodiment of
the adhesive roll construction 10 is there shown and comprises an
elongated strip 12 having a first end 14 (FIG. 2), a second end 16
(FIG. 2) and a pair of spaced and substantially parallel sides 18.
The strip is wound from the first end 14 and to the second end 16
into a tubular cylindrical roll 20 in which multiple layers of the
strip 12 overlap each other.
[0019] As best shown in FIG. 3, the strip 12 comprises a backing
layer 22 and an adhesive layer 24 on one side 26 of the backing
layer 22. Preferably, the adhesive layer 24 overlies the entire
side 26 of the backing layer 22 so that, when the strip 22 is wound
into the cylindrical roll 20, the adhesive layers 24 adhesively,
but detachably, engage the opposite side 28 of the backing layer 22
of the next outer layer of the strip 22 on the adhesive roll
20.
[0020] With reference now particularly to FIG. 2, the adhesive
roller construction 10 preferably includes a tubular and
cylindrical roller support 30 around which the strip 22 is wound
into the adhesive roll 20. Preferably, the roller support 30 is
made of cardboard although other materials, such as plastic, may
alternatively be used.
[0021] With reference now to FIGS. 1 and 2, at least one elongated
perforation 34, which may be a continuous slit, is formed through
the adhesive roll 20 so that the perforation 34 extends through
multiple layers of the strip 22. As best shown in FIG. 2, the
perforation 34 is preferably linear and each end 36 of the
perforation 34 is spaced inwardly from its adjacent side 18 of the
strip 22.
[0022] Still referring to FIGS. 1 and 2, unlike the previously
known adhesive roller constructions, the perforation 34 extends
diagonally between the sides 18 of the strip 22 such that the
longitudinal axis of the perforation 34 intersects the side 18 of
the strip 22 at an acute angle .theta. (FIG. 1). Preferably, the
perforation 34 terminates short of each side 18 of the strip 22,
but optionally extends to one or both sides 18 of the strip 22.
[0023] In operation, the adhesive roll 20 is typically rotatably
mounted to a handle (not shown) and rolled across clothing,
furniture or the like to remove detritus from the object. After
extended use, the outwardly exposed adhesive layer 24 on the
adhesive roll 20 becomes "used" so that its adhesiveness
diminishes. When this occurs, a single sheet, corresponding to one
revolution of the adhesive roll 20, is removed by tearing the sheet
40 along the perforation 34 thereby exposing a new adhesive sheet,
also corresponding to one circumference of the adhesive roll 20.
When the sheet 40 is removed until it again meets the perforation
34, the used sheet 40 is then torn from the adhesive roll 20 thus
exposing fresh adhesive around the entire circumfery of the
adhesive roll 20.
[0024] Since the perforation 34 is diagonally formed through the
adhesive roll 20, stress and the possibility of tearing the used
sheet 40 during the removal of the used sheet 40 from the adhesive
roll 20 is minimized. Instead, in practice, the used sheet 40
cleanly separates from the adhesive roll at the perforation 34.
[0025] From the foregoing, it can be seen that the present
invention provides an adhesive roller construction which not only
ensures that, upon removal of a single sheet 40 from the adhesive
roll 20, fresh adhesive is exposed on the adhesive roll 20 around
the entire circumference of the adhesive roll 20, but also
minimizes or altogether eliminates any possible tearing of the
sheet 40 during the removal process. Having described my invention,
however, many modifications thereto will become apparent to those
skilled in the art to which it pertains without deviation from the
spirit of the invention as defined by the scope of the appended
claims.
