FR2465457A1 - Clothing article protective cover - has insertion opening in lengthwise direction and with overlapping edges - Google Patents

Abstract

To protective cover is particularly for articles of clothing, comprising sections of plastic sheet sealed along the ends and with an insertion opening. The opening runs in the lengthwise direction of the sheet and has two overlapping edges, which come to lie between the lengthwise axis of the sheet and its lateral fold line. The sheet can be of polyethylene, polypropylene, or a copolymer of the two, with a thickness between 10 and 120 microns, and there can be an opening (T) in the top edge through which the hook of a clothes hanger can be passed.

Description

 The present invention relates to a method of protection or presentation that is to say, in fact, packaging of clothing or the like.

 Currently, various types of packaging are used for articles of this kind and these packages differ according to the users.

- Retailers and resellers of clothing supply themselves under
wind at several manufacturers who deliver the articles on
hangers. However, these end up becoming encom
brants insofar as they are not offered to customers.

In fact, resellers generally operate under their own
brand, cornmercial name or brand they wish to affix on
their own packaging: the clothes, once sold, are
therefore released from their anonymous hangers and placed in bags
made of synthetic resin or cardboard packaging bearing the
personalized brand of retailer or reseller.

Clothes can, moreover, be more or less
well in these bags or packaging, crumple and take
creases.

- Manufacturers of a certain category of clothing, in particular
shirts, have a presentation problem that
is particularly acute. Shirts supplied to retailers
are indeed mounted, folded and pinned manually on
cardboard rectangles. It is extremely difficult to automate
folding and pinning. In addition, the
cost of small supplies such as cardboard, pins, etc.

- The dyers, for their part, use covers, generally
ral formed by a section of a sheath which they unwind,
weld and cut as and when required.

After cleaning, the clothes are therefore placed in one of
these light covers - synthetic resin and most often
made from transparent film - that the client
usually carries on his forearm. Here again,
the garment may crumple, wrinkle and even what
sometimes it tends to slip out of its sheath.

- Finally, to pack clothes, we commonly sell in
the trade in covers - called travel covers - comprising
longitudinal opening allowing their introduction and suscep
tibles to be closed with a zipper or flap
longitudinal reel. However, the manufacturing cost of these em
ballage is quite high. In addition, repeated handling
closures, most often welded, can cause tears
It therefore arises in the clothing and clothing industry as well as for the handling and maintenance of clothing, many packaging, presentation and storage problems that the invention proposes to solve.

 This therefore relates to a cover, in particular for clothing, constituted by a section of sheath closed at its two ends, having an opening oriented substantially in the long longitudinal direction of the sheath and comprising overlapping lips.

 Such a so-called "wallet" cover is particularly economical to manufacture since it does not have an attached closure device. The overlapping lips are sufficiently dust-tight, especially since the lips tend to stick naturally to each other under the effect of static electricity charges when the cover is made of resin. synthetic.

 Thanks to the invention, shirt manufacturers can thus confine themselves to sliding their made-up articles inside these overlapping lip covers and obtaining a neat presentation and of a reduced cost.

 In addition, to be able to hang the garment once introduced in its cover, one can provide at one of the ends of the latter a hole for the passage of the hook of the same hanger on which the garment is threaded. Once the garment placed on its hanger has thus been slipped into the cover, the user can then pass the hook through the hole and suspend the whole by this hook. It can likewise hold it in the hand by means of a handle making the hook less shearing.

 The invention further relates to a process for the continuous production of an overlapping lip cover.

This process consists of
- form a flattened continuous sheath constituted by a strip
comprising two overlapping lateral wings brought back one
on the other so as to overlap by their edges,
- periodically cut the sheath from place to place, to de
bite sections,
- seal each of the two ends of each
sheath section thus obtained, in particular by reserving the part
central of one of these two welds to constitute the hole
of the hanger hook.

 The covers defined above of the "portfolio" type are thus obtained continuously.

Referring to Figures 1 to 4, we will first describe covers whose continuous manufacturing process will be described in more detail
detail while referring to Figures 5 to 9.

In FIG. 1, we see a cover constituted as follows
The two wings 2 and 3 of a thin and flexible rectangular sheet 1
are respectively folded down along edges 4 and 5 and according to the
arrows F4 and F5 so that their ends overlap under the
shape of lips 6 and 7.

The lip 6 corresponding to the widest wing is folded down at the
above the lip 7 corresponding to the narrower wing.

Sheet 1 is made in the form of a thin trans film
parent in polyethylene and the extreme edges of the wings are immobed
read in the folded position by two welds 8 and 9.

In this way, the assembly has a longitudinal opening,
since the lip 6 can be moved away from the lip 7 as indicated in the figure.

While welding 8 is carried out over the entire length of
the end of this assembly, on the other hand the welding 9 is only carried out on the sections 9a and 9b by reserving an unwelded zone in
the central part of the upper end of the cover.

 It can be seen that one can easily insert, according to arrow F1, a garment 10 into the cover by lifting the lip 6 according to arrow F2 until this garment exceeds the edge of the lip 7 .: the garment can then be suitably slid in the opposite direction, under this lip 7, in order to be able to be fully engaged flat under the wings 2 and 3.

 The garment is put in place in the cover with its hanger 11 whose hook 12 can be engaged through the hole T located on the upper edge 9 of the cover, which is accessible over the overlapped lip.

 Therefore, the assembly is presented under the aspect represented in FIG. 2.

 Thus, the garment is perfectly packaged in a cover devoid of any closure member and yet properly closed.

 Indeed, it is clear that the lip 6 is well supported on the lip 7, if only under the effect of electrostatic charges which develop under the effect of the slightest friction on the artificial resin film.

 In Figures 1 and 2, the garment has been shown mounted on its hanger, that is to say in the form where it is available in the clothing store. In this way, the retailer gets rid of the hanger supplied by the manufacturer at the same time as he hands over the garment to his client and he no longer finds himself confronted with the problem of the increasing congestion of hangers as and when he sells. .

 Nevertheless, the cover of FIGS. 1 and 2 can without any inconvenience be produced with a continuous weld 9, that is to say without a hole T.

This option is particularly advantageous for a shirt manufacturer who, having such covers, can pack his articles in a clean and neat manner without being forced to resort to traditional pins and cartons (Figure 2a).

 Likewise, this kind of cover can be used by dyers or launderers, either with a cheap hole and hanger, or without a hanger as in the case of shirts.

 Note that it is desirable for the upper lip 6 to correspond to the widest wing 2 so that the longitudinal opening is as much as possible cleared by the narrower wing 3 ia and so that the garment can then be easily engaged under the latter.

 It is obvious that your sheet 1 can be made of all kinds of synthetic resins (polyvinyl chloride, polyvinyl acetate, polyethylene, polypropylene, polyester, etc.), as long as it is sufficiently flexible, inexpensive, if possible solderable or even sticky and, finally, possibly transparent for the clarity of the presentation.

It also appears that the hanger can be absolutely arbitrary, so that the cover can be used indifferently
- either in combination with the relatively luxurious hangers offered
by the manufacturers for the good presentation of their articles
- either with the most basic type hanger and, in particular, this
him in simple wire commonly supplied by the dyers.

 Likewise, the low price of the cover means that it can be considered to be of the "throw away" type and of such a low price that launderers or shirt manufacturers can consider delivering the latter on good hangers. market to avoid unnecessary folding manipulations.

 Finally, it is clear that the hole T could be provided on any of the edges of the cover. However, it is preferable to provide it on one of the edges accessible over the overlapped lip 7 and, if possible, on an edge to be welded, which allows it to be produced by simple welding reserve.

 It will be noted, with reference to FIG. 2, that the garment placed in its cover is easy to handle and to transport by the hook of the hanger which supports it. To prevent this hook from shearing the fingers, it can be engaged in a suitable removable handle, so that the clothes thus wrapped and conditioned on a hanger can be very easily worn by passing the hook over the shoulder, as is become very common for classic travel covers.

 Furthermore, so that the cover matches the shape of the shoulders of the jackets and in order to prevent the upper corners from falling down by bending along the lines L1 and L2 (FIGS. 1 and 2-), it is purely and simply possible to realize by bias the welds 9a and 9b and cut along these lines L1 and L2.

 Referring now to FIG. 3, we will describe a process and arrangements which allow the garment to be easily slid into a cover of the type of FIGS. 1 and 2 when there is no flat surface suitable for facilitating the positioning. illustrated in figure 1.

 It is in fact understood that the introduction of the garment into the cover of FIGS. 1 and 2 then encounters practical problems, in the absence of a horizontal table for supporting the cover flat, since it then takes two hands to hold the cover (since it is devoid of any means of suspension) and two hands to slide the garment into the latter.

In order to resolve this difficulty, it suffices to modify the cover very slightly and to hang it by its upper part in the manner which will now be described.
Referring to Figure 3, we see that the edges of the hole T are reinforced. The reinforcement can be of the conventional type and consists of a narrow strip of cardboard or more or less stiff synthetic resin. Preferably, the strip is in the form of a small collar 15 of low height welded inside the lips of the hole T, substantially in the extension of the welds 9a and 9b.

 The assembly of the sheath and the small collar is pierced by a hole 14 which makes it possible to thread on a rod 15 a whole series of covers as illustrated in the figure which can be removed one after the other.

 It suffices to introduce the garment, mounted on its hanger, into the first available cover with one hand, spreading the lip 6 with the other hand, then reassemble and take out the hanger hook through of the hole T, the edges of which are separated if necessary by the hand released after lifting of the lip 6 (FIG. 4) and finally to grasp the whole by the hook with this hand M once the latter has been completely released from the hole T.

 If the covers are to be hung flat against the wall, it suffices to provide other small holes "t" through which the covers can be engaged on rods 15 ′ similar to rod 15.

 Instead of passing the hanger hook through the hole T, it could of course be provided for the small collar 13 to be fitted with a loop or a small hook allowing the hanger to be hung inside the cover.

 Referring now to FIGS. 5 to it, we will explain how it is possible to produce continuously, that is to say at very low cost, the "portfolio" covers illustrated in FIGS. 1 and 2.

 In FIG. 5, it can be seen that the sheet 1 and the wings 2 and 3 (FIG. 1) can be produced in the form of an assembly 16 from a continuous flat sheet 17. It suffices to pull this sheet in the direction of arrow F3, while raising the two edges in the direction of arrows F4 and F5. These continuous folding operations are carried out according to the well known packaging techniques in the paper and fabric industry.

Machines manufactured in this regard by the company DEUTSCHE
APPARATE VERTRIEBSORGANIZATION GmbH & CO constitute an example of those which can be used to carry out these foldings.

As seen in Figure 6, the sheath 16 prepared as it
is shown in figure 5 is brought on a continuous rolling table
21 circulating on rollers 22. It then suffices to weld and cut
sheath sections periodically to obtain comfortable covers
mes to that of Figure 1. This welding and cutting can be done
kill in the following way
The sheath 16 being immobilized with the table 21, it is lowered according to the
arrow F6 of the heating ramps 22a and 22b parallel and they are held in place for a sufficient time to weld the upper and lower sheets of the sheath (FIG. 7). To reserve the hole T, the heating ramp 22a has a notch 23.

 When the welds 30 and 31 are made (FIG. 8), a blade 24 is lowered (according to arrow F7) which is disposed between the two heating ramps 22a and 22b. In this way, each time that the assembly of the blade and the heating ramps is raised, a cover is produced from the flattened sheath of FIG. 5, while the part of this sheath which is located upstream of the mechanism is closed at its end by the weld 31. It then suffices to again pull the sheath 16 of sufficient length (in fact corresponding to the height of the garment to be packaged) to proceed with the manufacture of a new cover.

 When the covers are thus mass produced, they can be stored as shown in FIG. 10 in the form of a mattress 26 of covers 20 detached from one another. It is such a mattress which can be placed on the rods 15 and 15 ′ in FIG. 3, in particular at the dyers or at the clothing manufacturers, after having been perforated with the holes 14 and "t". Of course, in the case where small collars 13 must be put in place, it is then necessary to proceed cover by cover.

 Instead of cutting the covers in the sheath by means of a blade 24, one can (as shown in FIG. 9) limit themselves to "initiating" their separation by intermittent cuts 29 produced by means of a blade 27 furnished with a succession of teeth 28. The covers 20 thus produced can then be stacked in an accordion, as shown in FIG. 11.

 Of course, one could just as easily wind such covers - on a cylindrical mandrel, or any other similar support.

 In the case where the welds 9a and 9b must be organized at an angle, as indicated above, it suffices to give a corresponding shape to the ramp 22a and then to provide a cross section at the bottom of the cover and two oblique cuts to the part superior.

 The invention having now been explained and its interest justified in detailed examples, the applicants reserve exclusivity for the entire duration of the patent without limitation other than that of the terms of the claims below.
