The present invention relates to a packaged slide fas- ;
tener ready for sale at retail stores. ~ -
Individual slide fasteners of varying type~ si~e and
color are usually packaged and sold at retail stores to cus-
tomers desiring to buy one or more fasteners which meet their
requirements. One known packaged slide fastener comprises an `
elongated cardboard, a slide fastener placed on the cardboard
and a transparent film of plastic material covering the slide
i fastener. The cardboard and the film have a width greater than
that of the slide fastener and are bonded to each other with an -
adhesive along the margins of the film in order to enclose the
slide fastener. With the conventional package construction,
a clearance space must be provided a-ound the slide fastener -
to prevent the latter from adhering to the cardboard.
Therefore, the slide fastener tends to shift under the plastic
film and finally becomes wavy or wrinkly during shipment~
r~ storage and display, thereby makin8 the packaged slide
fastener less attractive. ;~
Purthermore, the side edges of the cardboard are
exposed snd susceptible to damage or deformation when in colli-
sion with foreign ob~ects mainly during~-shipment, with the
result that the plastic film is liable to peel off.
Accordingly~ it is an object of the present invention
to provide a packaged slide fastener in which the slide fas-
,~ .
tener can be supported stably in place within the package.
Another object of the invention is to provide a packagedslide fastener which is rigid enough to avoid any damage or
deformation.

In accordance with the invention, a packaged slide fas-
tener comprises an elongated base plate, and a slide fastener
placed on one surface of the base plate, the base plate being
substantially coextensive in width to the slide fastener and
having a length greater than that of the slide fastener. An ~
elongated plastic film has substantially the same length as ,'
.
~ the base plate and has a width greater than that of the base
,~ plate. The plastic film covers the base plate and the slide
; fastener thereon and has side margins foIdedback over the side
~, 10 edges of the base plate. The folded margins of the plastic "
: - .
~'~ film is adhered to the other surface of the base plate, the '`-' -
base plate having a portion of said one surface covered ~''
'~ directly with and adhered to the plastic film, and there being `,'
,~ a cutout recess in the portion.
~ 15 Other features and'advantages of the invention will be~
,~ come apparent from,the following description taken in conjunc- ~
~ tion with the accompanying drawings. ~ i-

Turning firstly to the description of Prior Art as
contained in page 2 of the present Specification and ;
referring to Figs. 7 and 8, it will be appreciated on review --
of the Figs. 7 and 8 that the elongated cardboard is -
referred to with reference numeràl 10~ the slide fastener has
reference number 11~ the transparent film is 12, the margins
are referred to with 13 the clea'rance space is 14 and the
side edges are referred to with reference numeral 15.
In Figs. 1 and 2~ a packaged slide fastener 20 comprises
an elongated base plate 21 made preferably of cardboard or
plastic sheet material having substantially the same stiffness
as the cardboard, and a slide fastener 22 placed on a front
I surface of the base plate 21.- The base plate 21 has a trans-
verse dimension or width substantially equal to or slightly
narrower than the slide fastener 22 to be sold. The base plate ;~
~!~ 21 is longer than the slide fastener 22, and the length of the
base plate 21 relative to that of the slide fastener 22 must
be such that when the base plate 21 carries the slide fastener
22 thereon, the base plate 21 affords a portion 23 at one end
`) of the slide fastener 22~ which portion 23 long enough to
permit a cut-out recess 24 to be formed therein. The~packaged
slide fastener 20 can be hung down for display on a hook (not
d shown) extending through the recess 24.
The base plate 21 and the slide fastener 22 thereon are
covered with a plastic film 25 which is substantially coexten-
.,:.~ .

sive in length to the base plate 21 and is greater in width
than the base plate 21. As shown in Figs. 3 and 4, side mar-
gins 26 of the plastic film 25 are folded back over the side
edges 27 of the base plate 21. The folded film margins 26
are bonded to the reverse surface of the base plate with an :`~
adhesive, or are heat sealed thereto by means of a suitable
'~eat sealing equipment, in which case the base plate, if made

of cardboard, should have a porosity enabling such heat seal- `
ing. The plastic film 25 is bonded or heat sealed also to
the front surface of the portion 23 of the base plate 21 for
reinforcement thereof. The recess 24 is formed after the por-
tion 23 is covered with the plastic film 25. Since the slide
fastener 22 is substantially conterminous in width with the
base plate 21, and has its side edges pressed against the base -;`
plate 21 by physical contact with the film 25, the slide fas-
. .';
tener 22 is retained stably in place on the base plate 21
against displacement during shipment and display. The packag- ~.
ed slide fastener 20 of the invention is more attractive
because an area where the plastic film 25 is adhered to the
base plate 21 is not exposed to sight. The film-covered side
~ edges 27 of the base plate 21 can be protected from damages
,; 15 due to physical contact with foreign objects.
The plastic film 25 is preferably transparent to allow ~ ~ -
visual inspection of the slide fastener 22 being packaged, but ,~
~the fiIm 25 may be colored provided it does not disturb such `'~`
visual inspection.
As shown in Fig. 5, the base plate 21 has an opening 28
for permitting customers, for example, to physically check or
. . .
, ~ directly inspect the fastener tapes fortheir hue or fabric, ; ~ -
and the fastener elements for their shape. The base plate 21 ;
also has a perforation 29 formed therein and extending between :
the opening 28 and a bottom end of the base plate 21 so as to
facilitate tearing of the base plate 21 along a predetermined ~ `
line when the slide fastener 22 is to be taken out. There is
an aperture 30 formed in the base plate 21 at a position corres-

ponding to the slider31 of the slide fastener 22, the aperture
30 serving to receive therein the bottom wing of the slider 31
to lock the latter in place positively and reliably.
Fig. 6 illustrates an alternative form of a plastic film -'~
32 in which a cutout 33 is provided for the slider 31 to pro-
ject therethrough. With this cutout 33, the film 32 is free `
of localized deformations and damages which might otherwise
take place with the film 25 (Fig. 2) covering the projecting
slider 31. Formation of the cutout 33 is beneficial especial- ~-
ly when the plastic film is used with a slider of high profile. ~i
