[0001] This invention relates to a duster-polisher made of plastic film which is suitable
for dusting clothes and the like and also for polishing shoes, bags, furnitures and
others.
[0002] A duster made of plastic film by overlapping two rectangular sheets thereof, and
connecting each opposing side to form a folded cylinder, or further sealing one of
the remaining open sides to form-a pocket, one face thereof being coated with a pressure
sensitive adhesive so as to afford a dust catching ability, is known for some time.
Usually, the adhesive layer is covered with a protector film with an alienating adhesive
layer interposed therebetween to keep the adhesive face clean. The cylinder part,
or in other words, the pocket with or without bottom functions as a hand pocket to
hold the gadget.
[0003] If one face of the pocket is made soft and rough, preferably spongy, instead of coating
with the adhesive, it can serve as a handy polisher.
[0004] A duster-polisher having both functions of dusting and polishing and eliminating
protector film by using the back face of the polisher therefor, is handy and economical.
Outer faces thereof may be used as a printing space for advertisement or other purposes.
But no such gadget has ever been proposed.
[0005] Accordingly, an object of this invention is to provide a handy duster-polisher made
of plastic film having a face coated with a pressure sensitive adhesive for dusting
and a soft and rough face for polishing.
[0006] Another object of this invention is to provide a less expensive duster-polisher of
throwaway nature which has convenient printing spaces at the outer faces thereof for
advertisement or other commercial purposes.
[0007] Other aspects, objects, and several advantages of this invention will become apparent
from reading of the following disclosure and the accompanying drawings.
[0008] To summarize, this invention provides a duster-polisher which comprises at least
one pocket with.or without bottom made of plastic film, one face thereof being coated
with a pressure sensitive adhesive to define an adhesive layer, which is, in turn,
protected with a back face of a polisher, with an alienating. adhesive layer interposed
therebetween. The polisher may be a sheet of plastic film or a pocket with or without
bottom made of plastic film, one face thereof being flat and smooth to serve as a
protector film for the dust catching adhesive layer, whereas the other face, soft,
rough and preferably spongy to serve as a polisher face.
[0009] The above and other objects of this invention will be seen by reference to the description
taken in connection with the accompanying drawings, in which:.
Figure 1 is a perspective view, partly cut away, of an embodiment of this invention
having a hand pocket with bottom,
Figure 2 is the perspective view shown in Figure 1, but with the polisher film acting
as an adhesive protector partly taken off to show how to expose a fresh adhesive layer,
Figure 3 is a perspective view, partly cut away, of another embodiment of-this invention
wherein the hand pocket is bottomless,
Figure 4 is a perspective view of still another embodiment of this invention, wherein
the polisher part consists of two sheets of plastic film overlapped and connected
at each opposing side and at a remaining side to form a pocket with bottom, and
Figure 5 is a cross sectional side view, partly enlarged to show the layer structure,
of the embodiment shown in Figure 4.
[0010] Referring now to the drawings, wherein like reference characters designate like or
corresponding parts throughout, Figure 1 shows an exemplary embodiment of-this invention
which has a hand pocket 1 with bottom 2. This pocket can be made of two rectangular
sheets of plastic film overlapped one upon the other,'and connected at each pair of
the opposing sides 3, 3 and a pair of the remaining sides, by means, for example,
of heat sealing. A less expensive version may be made by folding extruded thermoplastic
film cylinder to form two overlapped sheets connected, cutting laterally at a suitable
length and heat sealing at one of the open ends. The means for making the pocket does
not constrain the invention.
[0011] The upper face of the pocket 1 is coated with a suitable pressure sensitive adhesive,
for example, of rubber type, polyacrylate type, or polyvinylether type, to define
an adhesive layer 4. The lower face of the film 6 is preferably flat and smooth to
serve as a protector for the adhesive layer 4, while the upper face thereof is made
soft and rough, and preferably spongy, so as to act as a polisher face. The film 6
and a pocket 16 which will be mentioned later, have the same functions of protecting
the adhesive layer 4 and serving as a polisher, and will be called "polisher" or "polisher
part" when convenient. The film 6 may preferably be made of so-called non-woven, flocked,
or bonded fabrics having the above mentioned characteristics. Between the adhesive
layer 4 and the film or polisher part 6, a layer of alienating adhesive 5 is provided
to enable easy removal of the polisher part 6 from the adhesive layer 4. This special
adhesive hardly adheres to the pressure sensitive adhesive, but suitably attaches
to the film 6, and may be selected, for instance, from copolymers of higher alkyl
acrylate and other acrylic or vinyl compounds or both, some waxes, or certain silicone
resins or others.
[0012] The convenient size of the-hand pocket l, accordingly, the size of the duster-polisher
of this invention, may be such that the four fingers of a hand except the thumb can
loosely fit therein.
[0013] In order to use the duster-polisher of this invention as a polisher, simply insert
the four fingers into the pocket 1 such that the rough face of the polisher faces
palmside, and rub or polish the object. On the other hand, in order to use it as a
duster, insert the four fingers, as before, into the pocket 1, and remove the polisher
part 6 and expose the fresh adhesive layer 4 as depicted in Figure 2, and tap or slowly
rub the object therewith. As well known, fresh adhesive face loses dusting ability
with elapsed time.
[0014] Another embodiment of this invention shown in Figure 3 has a bottomless pocket 1.
Because the four fingers can go through the pocket, the depth thereof can be made
shorter and less expensive.
[0015] The further embodiment shown in Figures 4 and 5 is different from the one shown in
Figure 1 in the respect that the film 6 therein is taken over by a pocket 16 (as mentioned
above, will be called polisher or polisher part according to the context) consisting
of two sheets of plastic film of the lower sheet l6a and the upper sheet 16b connected
to each other in a similar.manner as in pocket 1. The lower sheet is flat and smooth
and functions as a protecter for the pressure sensitive adhesive layer 4, with the
alienating adhesive layer 5 interposed therebetween, and the upper face of the sheet
16b is made soft and rough,' and preferably spongy, so as to.serve as a polishing
face. As a matter of course, the pocket 16 may be made bottomless to combine with
the pocket 1 depicted in Figure 3. The embodiments of this type have an advantage
in being able to serve as a duster and, at the same time, as a polisher, by separating
them at the alienating adhesive layer 5.
[0016] In all embodiments above mentioned, the lowermost' face and if desired, the uppermost
face thereof, can be used as a printing space wherein instructions of using the gadget,
advertizing or any other messages are written.
[0017] The duster-polishers of this invention naturally belong to a so-called throwaway
article, and may cause tack trouble when thrown away. However, this can be completely
avoided by turning the pocket inside out.
[0018] The term "plastic film" as used herein and in the claims are intended to include
film of plastics such as polypropylene, polyethylene, polyvinyl chloride, polyvinylidened
chloride, polyamide, celulose (celophane) and the like for the duster part, whereas
for the polisher part, to include further film of non-woven, flocked and bonded fabrics
made of plastics.
[0019] This invention may be embodied in other specific forms without departing from the
spirit or essential characteristics thereof. The present embodiments .are therefore
to be considered in all respects as illustrative and not restrictive, the scope of
the invention being indicated by the appended claims rather than by the foregoing
description and all changes which come within the meaning and range of equivalency
of the claims are therefore intended to be embraced therein.
