Description

1 2752823

  The present invention relates to a device for dispensing fragmented adhesive strips, in particular dressings, said device

  allowing the removal of a strip fragment using one hand.

  PRIOR ART The use of adhesive tapes generally leads first of all to the need to take a fragment of a strip: this fragment can be cut from a strip wound on itself without a protector, or from a strip wound and provided with a removable protector, or according to a different presentation, the fragment is already precut and provided with a

removable protector.

  The wound tapes are for example adhesive tapes 1.5 for packaging, DIY, insulation, or intended to fix objects or documents: known distribution systems are reels, generally equipped with a cutting system. These dispensers can be simple or more sophisticated, such as the dispensers for packaging tape or the weighted office dispensers which allow

  unroll a piece of tape and cut it with one hand.

  The ribbons in the form of precut fragments are, for example, the dressings, presented with a removable protector, in particular when these so-called dressings are provided with a compress; such a presentation which has the advantage of authorizing individual packaging, has an important drawback: the provision of the dressing in its useful state, that is to say extracted from its packaging and released from a part in

  less of the protector, requires manipulation with both hands.

  However, it turns out that the nursing staff or the patient himself may simultaneously have the need to maintain, for example, a compress which must be held by the dressing and, therefore, does not have two hands to prepare the dressing. In this case, the nursing staff requests the patient's help or prepares the dressing before performing his intervention, at the risk of polluting him during this waiting period. It was therefore desirable to find means of distribution for

2 2752823

  fragments of adhesive tape such as dressings, which are capable of

  release a fragment using one hand.

  For example, in this field, the patent FR 2 409 210 is known in which dressings, presented in a pouch, have one of the two half-protectors maintained in the packaging and can be removed leaving at least part of the protective sheet in the packaging: this arrangement avoids having to remove one of the protectors, but it is still necessary to have both hands to remove the dressing while

now the cover.

  FR-A-2 409 210 relates to a packaging and its manufacturing process, the packaging for medical plasters consisting of two sheets connected together along two of their edges and between which are placed plasters each covered with two removable half-protectors . Above a first of the half-protectors is provided a fixed retaining means which allows, when pulling on the end of the plaster covered with the second half-protector, to extract the plaster from its packaging while by separating it from the first half-protector that remains in the packaging. Separation lines are provided in the packaging in order to make individual packaging for each plaster, as is

  moreover known in the field of packaging for dressings.

  This packaging nevertheless has the disadvantage of requiring both hands of the attendant to extract the plaster or dressing from

  general packaging or individual packaging.

  According to one variant, the general packaging of several

  plasters are joined together and arranged in a pocket.

  But then again, you have to hold the cover with one hand and extract

the plaster with the other hand.

  In FR-A-2 422 389 there is described a box or container intended to receive a pouch of packaging for plasters as described in FR-A-2 409 210. The extraction of plasters still requires the use of two hands of the attendant because it is necessary that he holds the case with one hand to extract, with the other hand, a plaster. To avoid the loss of unused plasters or dressings forgotten at the place of use, it is planned to fix on a wall the box, the fixing being able to be carried out by screwing or using a self-adhesive means , so as to keep fixed

3 2752823

  in a specific location, all the dressings and only authorize the removal of a reduced number of individual dressings depending on the care to be operated. But when the dressings, in their collective or individual packaging, are brought to the place of use, it is necessary, once again, to use two hands to extract each dressing. OBJECT OF THE INVENTION The present invention provides a new device for dispensing fragments of adhesive strips, in particular adhesive dressings, which has the advantage of making these adhesives accessible using a single

hand in the place of use.

Description

  According to the invention the dispensing device for fragments of adhesive tape, arranged on an anterior face of a support sheet, is characterized in that at least a portion of the tape fragments is adhesive-coated on said anterior face of the support sheet and in that it further comprises means for making said support sheet integral

  with a receiving element intended to receive said device.

  The main application of such a device is the distribution of self-adhesive dressings, especially when used in the laboratory.

or in hospitals.

  The invention also finds its utility for the practical provision of fragments of adhesive tape, in particular for packaging operations or technical fastenings, such as for example in mounting.

electrical circuits.

detailed description

  The main application of the invention being a distributor of

  adhesive bandages, the following detailed description is made for this

  particular example. This should not constitute a limitation to the device which can be used analogously for any type of adhesive tape

usable in fragmented form.

  To make a dressing dispensing device according to the invention, a support is used in the form of a sheet of paper or plastic material, one of the so-called anterior faces is coated with a non-stick layer and a one is placed on this first face. or preferably, several dressings arranged in parallel. We then set a

4 2752823

  adhesive strip on the second face of the support and called posterior or back, so as to adhesive, for example, one of the two edges of the support corresponding to the end of the dressings. This adhesive strip can be obtained by depositing a layer of adhesive mass by known techniques or by fixing a double-sided adhesive strip. We thus obtain a

simple version of the invention.

  To implement the invention, the user fixes the support sheet on a surface a receiving element, for example a table or a cart or any other hard surface located near the place of care, by means of the strip. adhesive. He can then remove the dressings individually by removing them with a single

  hand, the support sheet remaining firmly attached to the receiving element.

  The dressing removed is released from its protector when the latter is provided and it can be directly used to, for example, keep a

tampon or close a wound.

  Preferred embodiments of the invention are described below.

  after, with reference to the accompanying drawings in which: - Figure 1 is a perspective view of a dressing dispenser according to a first embodiment according to the invention, - Figure 2 is a sectional view along AA 'of the dispenser according to Figure 1, - Figure 3 is a sectional view of a dressing dispenser according to a second embodiment of the invention, - Figure 4 is a sectional view of a dressing dispenser according to a third embodiment of embodiment of the invention, - Figure 5 is a perspective view of a dressing dispenser according to a fourth embodiment of the invention, - Figure 6 is a rear view of the dispenser according to another embodiment of the invention, - Figure 7 is a schematic exploded perspective view

  a dispenser according to another embodiment of the invention.

  FIG. 1 represents a perspective view of a dispenser 1 of dressings according to the invention, comprising a support sheet 2 of which one of the faces 2a, called the anterior, is provided with a non-stick coating and

  which carries on this face 2a adhesive dressings 3 arranged in parallel.

2752823

  On the face 2b, called rear or back, of the support 2 is fixed a double-sided adhesive strip 4, parallel to one of the longitudinal edges 5 supporting one end of the adhesive dressings 3. Preferably, the adhesive strip 4 is fixed near one of the edges 5. The support sheet 2 is intended to be fixed to a receiving element 10 which can be constituted by any hard surface located near the place where care is carried out for example. As the support sheet 2 must be kept firmly fixed on the receiving element 10, an adhesive is chosen for the strip 4, the adhesive power of which is very much greater than the adhesive power of the adhesive dressings 3 on the face 2a of said sheet. support, so that when one of the dressings 3 is separated from the support sheet, the latter does not separate from the reception element 10. Thus once the support sheet is fixed to the reception element, the attendant can separate the dressings with one hand

  after the others, according to his needs.

  2 shows a section along AA 'of the dispenser 1, according to which there is the support sheet 2, the dressing 3 provided with a pad 3a, adhesive on the non-stick face 2a of the support 2, the adhesive strip 4 fixed on an edge of the second face 2b of the support sheet 2 2o and a removable temporary protective sheet 6 covering the strip

adhesive 4.

  The following figures represent variants of the device, which retain the principle of the adhesive support, but include modifications intended to facilitate the removal of the dressing in the

  usual conditions of use.

  FIG. 3 represents a sectional view of a dispensing device according to which the dressings 3 provided with the pads 3a are fixed on the non-stick face 2a of the support sheet 2 so that one end 3b of the dressing protrudes from the support sheet 2 so as to be o accessible or free and not protected by the support sheet 2. The adhesive strip 4 is fixed to the rear face 2b of the support sheet 2, on the border corresponding to the free end 3b of the dressings 3. On then place a non-stick protector 6 which covers both the end 3b of the dressings and the adhesive tape 4. It would also be possible to place a first non-stick protector covering all of the

6 2752823

  ends 3b then a second protector covering the adhesive strip 4. The non-stick protector may slightly exceed the end 3b and / or the

  adhesive strip 4 to facilitate its gripping.

  To use this dispensing device, the protector 6 is removed and the device is fixed, by means of adhesive 4, to the edge of a receiving element such as a table so as to allow it to protrude outside of the table the ends 3b of the dressings 3. The end 3b is thus very easy to grasp and allows the dressing to be detached from its support with great ease. _0 FIG. 4 represents another variant of the device according to the invention in which the dressings 3 are arranged on the support sheet 2 in a similar manner to the device of FIG. 3, with a part 3b of the dressing projecting, but each of the dressings 3 is individually covered on its end part 3b with a non-stick protector 7 provided with a gripping fin 7a. The adhesive strip 4, always positioned near the edge supporting the ends 3b of the dressings, is covered with a temporary protector 6 which covers only the adhesive strip 4. To use this device, the dispenser is fixed by means of

  the adhesive strip 4 on a flat surface, after removal of the protector 6.

  Each dressing can then be grasped individually by its end 3b which remains protected by the non-stick film 7. After partial positioning of the dressing on the patient, the protector 7 is removed in the usual way by pulling the grip wing 7a, which then allows to fix the end 3b to complete the application of the dressing. In this case, we can

  note that the user never touches the adhesive portion of the dressing.

  It will also be noted that all of these operations are carried out using a single hand, this constituting a significant improvement over the

  techniques known from the prior art.

  When it comes to surgical adhesives, the dispensing devices as described above are preferably presented in a sealed package so as to preserve the cleanliness and sterility of the dressings. As indicated previously, this type of device, described here for dressings, also finds its application to facilitate the distribution of fragments of adhesive strips such as those commonly

7 2752823

  used during packaging operations, or for fixing operations in industry, or for the distribution of labels intended for a

manual installation.

  The various components of the dispenser are of a nature known to those skilled in the art; the support sheet is of a type generally used to obtain peelable protectors on pressure-sensitive adhesives: it is for example a sheet of paper or a sheet of polyethylene coated on one of its faces of a non-stick varnish, for example based on silicone. The adhesive strip 4 is obtained by applying either a double-sided adhesive tape o10, or a single layer of a pressure-sensitive adhesive, these two products being placed with the peelable protector or

protective sheet 6.

  According to a practical aspect of the invention, it is advantageous that the support sheet 2 is transparent and that the adhesive strip 4 is colored, so as to be visible through the support sheet 2; this identification facilitates the installation of the device on the reception surface, in particular when

  wishes to fix the latter on the edge of a table.

  In the case of the variant represented according to FIG. 4, the half

  peelable protector 7 is preferably a polyethylene film.

  The example of embodiment which follows makes it possible to better appreciate the invention. A strip of siliconized paper is used on one side (reference HV67368 supplied by the company 4P-Rubesil) 8 cm wide and dressings provided with a compressive pad in their central part are fixed transversely to the silicone side. Dressings with a unit size of 8cm x 4cm are fixed about 1 cm from the edge of the strip of silicone paper and therefore protrude by 1 cm on the second edge of the strip. The protruding part of the dressings is then covered with a strip of silicone paper on one side (silicone side against adhesive of the dressing) of

2 cm wide.

  Then fixed on the second edge of the first strip of silicone paper, on the non-stick side a strip of double adhesive tape

face about 10 mm wide.

  This double-sided tape consists of a polypropylene support film carrying on one side a pressure-sensitive adhesive based on

8 2752823

  natural rubber colored blue and on the second side a pressure-sensitive adhesive based on acrylic polymers, coated with a temporary non-stick protective film. The double-sided tape is fixed to the second edge of the paper support by means of the rubber-based adhesive. The strip thus obtained is cut into fragments each containing 5 dressings thus constituting dispensers of 5 dressings according to the invention which are individually conditioned and sterilized. Such a dispenser finds its application for example in a practitioner performing sclerosis of varicose veins. After opening the sachet containing the dispenser, the practitioner removes the protector from the double-sided adhesive tape and fixes the dispenser on the edge of a table so as to allow the shortest side of the dressing to protrude from the table. He then removes the strip of paper

  narrow silicone, thus releasing approximately 1 cm from the end of the 5 dressings.

  These can then be grasped with one hand to be used according to

needs.

  According to another exemplary embodiment, shown diagrammatically in FIG. 5, a polyethylene film support strip (2) is used and a strip (8) of pressure-sensitive single-sided pressure-sensitive adhesive tape is fixed on the non-stick face 2a. about 1 cm (an adhesive mass based on natural rubber is used). The free adhesive part is covered with a

  removable protector (9) made of silicone paper. Then place

  dirty dressings (3) coated on one end with a removable protector 7 provided with a fin 7a. These dressings are placed in such a way that the end carrying the protector 7 exceeds the adhesive edge of the strip.

support 2.

  A device according to the invention is thus obtained which can be fixed to a table for example, by means of the free adhesive part of the tape 9 and from which each of the dressings 3 can be easily removed by grasping the end of the protector 7. then known manner, the protector 7 can be removed after fixing the other end of the dressing on the patient's skin. This device avoids any contact between the fingers and the adhesive part

bandage.

  The examples described above for dressings are not limiting and the dispensers according to the invention also find their

9 2752823

  application to make it easier to apply labels or fragments

  adhesive tape in industry.

  According to another variant shown in FIG. 6 which represents the device according to the invention, seen from its back or rear face 2b, a line of least resistance 11 which extends in a direction D1 is formed on said rear face 2b which is transverse to the direction D2 of the dressings 3, that is to say parallel to the longitudinal edges 5 of the support sheet 2. In this case, the adhesive tape must be provided at a location which is further from the edge 5 than in the embodiments shown in the previous figures. In this way and once the support sheet is fixed on a receiving element, we can detach the part 12 of support sheet located between the line of least resistance 11 and the nearest edge 5, which releases a part 13 dressings and makes them accessible, all these operations can be performed with one hand

  after fixing the support sheet 2 on the receiving element.

  One can also provide lines of additional resistance 14 which are formed between the dressings 3 and directed in the direction D2 of said dressings. In this way, it is possible to release only one dressing, the others remaining fixed on the support sheet 2 and

  without presenting any part 13 devoid of protection.

  According to the variant shown in FIG. 7, a protective sheet 15 is fixed, for example by means of heat-sealing along the edges 5, to the support sheet 2. The connection between the two sheets 2 and is referenced by lines 16 in FIG. 7. In addition, lines of less resistance 17 can also be provided on the protective sheet 15, coincident with lines of less resistance 18 of the support sheet, so as to delimit individual packages for each of the dressings 3, the lines of least resistance 17 and 18 being directed parallel to said dressings 3 or in the direction D2 defined in connection with FIG. 6. Obviously, when the device according to the invention comprises lines of least resistance 14, the latter are found to be constituted by a part of the lines of least resistance 18, when the two embodiments of FIGS. 6 and 7 are combined. It goes without saying that q to obtain an individual separation of the fragments of tape, the adhesive tape 4 or the associated members such as one or more of the

2752823

  removable protectors described in connection with the other embodiments, is also provided with lines of suitable lower resistance so that when a dressing 3 is separated, the assembly constituted by the part of the support sheet and possibly the corresponding part of the sheet protective and said dressing comprises a portion of the adhesive strip 4 for fixing said assembly on a receiving member and allows

  then the separation of the dressing with one hand.

  In the foregoing, reference has been made to a continuous double-sided adhesive strip 4. However, the adhesive strip concerned may be discontinuous and consist of several adhesive zones, for example in the form of separate patches, so as to achieve the desired result. which is the attachment of the device to a receiving surface. The areas or adhesive pads are more particularly suitable for the embodiment of Figure 7 because they avoid the formation of lines of lesser

  resistance in the adhesive strip 4.

  The packaging of the dispensing device according to one of the embodiments of the invention described above can be provided in several forms. In a first form, it is possible to produce support sheets 2 comprising a predetermined number of strip fragments 3, for example

  between five and ten, then insert several sheets of support in a pocket.

  In a second form, one can provide a support sheet with its strip fragments which is long and wound in the form of a roll, the number of strip fragments necessary for an operation.

  particular being detached by the attendant, as and when required.
