Description

Fluid product dispenser

technical field

The present invention relates to a fluid product dispenser comprising a fluid product reservoir, a dispensing nozzle and spring means, the reservoir forming a movable or deformable action wall capable of moving or being squeezed, the spring The device is capable of forcing the deformable wall to a state of maximum reservoir volume. For example the dispenser or at least the reservoir can be made from one or two sheets forming the active walls. The inner volume of the reservoir is reduced by pressing the action wall against the spring means, so that the fluid product flows out through the dispensing orifice. This is a traditional design for a perfume, cosmetic and pharmaceutical dispenser.

In the case where the movable wall is deformable, spring means act on the movable wall to deform it towards a state of maximum deformation, in which state the movable wall forms a state of maximum volume of the reservoir. The deformation of the deformable wall by the spring means is not always aesthetically pleasing and may disrupt the shape of the dispenser. In addition, the spring arrangement increases the overall thickness of the dispenser, which may be a major disadvantage in some use cases.

Background technique

In fact, a dispenser of this type is known from document FR-2 791 645, the dispensing hole of which is blocked before use by a removable blocking mechanism. The interior of the reservoir is thus disconnected from the exterior and, according to this document, the spring acting on a deformable wall is compressed to a maximum extent so that the thickness of the dispenser can be kept to a minimum. This is a most important requirement when it is desired to clip such a dispenser in a magazine in the form of a fluid product sample. Even when the dispensing orifice is blocked, the spring apparently acts on the deformable wall, causing an unsightly deformation of the deformable wall, so that the deformable wall often exhibits irregular undulations.

Dispensers of some old crafts are also known whose action walls are not deformable, but only movable.

Contents of the invention

The object of the present invention is to overcome the above-mentioned disadvantages of the old technology and to create a dispenser for fluid products in which the spring means do not spoil the aesthetics of the operating wall at least before the dispenser is used.

In order to achieve this object, the invention proposes that the spring device cooperates with a starting device (des moyens d'armement) capable of driving the spring device to actuate the action wall from an initial state in which the spring device does not actuate the action wall. Thus, the spring means do not actuate the action wall in the initial state, so the spring means are given their actual and desired function, ie actuation of the action wall, by means of the activation means. The dispenser according to the invention can therefore be stored in a state in which the spring means does not act on the actuating wall before use. Since there is no actuation, the action wall remains stress-free and thus has a suitable aesthetic appearance.

The spirit of the invention is that the spring means perform their function only when required, ie just before using the dispenser. Thus the action wall and the dispenser remain in a completely flat state and can be used as samples in magazines.

According to one embodiment, the activation means are located outside the reservoir. For example, the starting device may comprise a rotary action mechanism. But a rotating or moving action mechanism is also conceivable.

Preferably, the spring means and the starting means are realized in one piece.

According to another aspect of the invention, the spring means extend in the reservoir, below the action wall. As a variant, the spring means are integrated with the action wall.

According to another aspect of the invention, a deformable region connects the spring means and the actuating means. Additionally, the deformable region can be rotated to form a fold or hinge line.

According to another aspect of the invention, the spring means and triggering means comprise a substantially rigid foldable part forming an inner part extending inside the reservoir and an outer part extending outside the reservoir, the inner part forming the spring means , the outer part forms the starting device.

According to a practical embodiment, the reservoir comprises two flaps, one of which forms the active wall, between which the substantially rigid foldable element extends. Additionally, a substantially rigid substrate is interposed between the two sheets, said substrate forming a substantially rigid foldable part.

According to one embodiment, the substrate comprises a reservoir portion forming a recess, which portion forms with two wafers said fluid reservoir. The base sheet additionally includes an active portion connected to the reservoir portion along a fold line. The reservoir portion and the action portion are preferably of the same size so that they overlap each other after being folded along the fold line. Additionally, the inner portion of the folded element of the substrate is in the same plane as the reservoir portion before the active portion of the substrate is folded to form the outer portion of the folded element.

According to another feature of the invention already introduced in document FR-2 791 645, the dispensing orifice is blocked by a detachable blocking mechanism. Additionally, the reservoir contains very little fluid until the removable plugging mechanism is removed. Before removing the removable blocking mechanism, or more generally before using the dispenser, the actuating means can be actuated to activate the spring means to actuate the actuating wall. Before the starter is activated, the spring device is ineffective on the action wall.

According to another embodiment, the activation means are located in the reservoir. For example, the spring means may be in the form of a leaf spring comprising an activation means which is only effective after the leaf spring has initially relaxed.

According to another embodiment of the invention, the spring means comprises a flexible front plate and a rear plate, the reservoir is located between the front and rear plates, and the triggering means comprises lateral support means which can be located between the front and rear plates, so that The front and rear panels are spaced at least partially apart from each other so that the flexible front panel is elastically deformed by approaching the rear panel to compress the reservoir located between the front and rear panels. Advantageously, the lateral support means can be selectively moved between an inactive position, in which the two plates are substantially parallel, corresponding to the minimum volume state of the reservoir, and an active position, in which the two plates are separated from each other. Advantageously, the lateral support device includes a turn-over part that is hingedly connected with the front and rear panels respectively at a hinge line, and forms an abutting edge for abutting contact with the rear and front panels respectively, and the turn-over Parts are essentially indeformable. Advantageously, the dispensing orifice is blocked by a detachable blocking means, provided with common action means to successively remove the detachable blocking parts and to place the transverse support means in place between the two plates. As a variant, the spring means comprise a front plate and a rear plate, the actuating means comprise transverse support means which can be positioned between the front and rear plates so as to separate the front and rear plates from each other at least partially, the transverse support means being elastically deformable, The front and rear panels are made close, thus squeezing the reservoir located between them.

Detailed ways

In the embodiment of Figures 1-5, the fluid dispenser comprises a plate or substrate 1 having a thickness of eg 1-2 mm and also a certain rigidity. For example a plate made of a suitable plastic can be used. In addition to the substrate 1 , the dispenser comprises two wafers 2 and 3 on each side of the substrate 1 . At least one of the two sheets, for example sheet 2, is soft or deformable. The other sheet 3 can also be soft or deformable. However, it is also conceivable to have a completely rigid body 3 or even merged with the substrate 1 . In practice, it is not excluded that the substrate 1 may form a bottom in the shape of a wafer 3 .

The substrate 1 also forms a dispensing hole. More precisely, the substrate 1 may comprise or form a groove in which a support element 4 forming the dispensing hole 41 is received. This supporting element 4 is additionally used to securely hold an element 5 of a porous material capable of imbibing a fluid product by capillary action. Of course, this is only a special embodiment, and it is entirely conceivable that some distribution holes are formed directly by the substrate or even in one of the two plates 2,3. In other words, the exact location of the dispensing holes is not a critical feature to the invention.

According to the invention, before using the dispensing hole, the dispensing hole 41 is blocked by a detachable blocking mechanism 6, which can be in the shape of an easy-to-grasp reed. In order to open the dispensing hole 41, it is only necessary to pull the reed 6 and pull it out from the substrate 1. Other shapes of removable blocking mechanisms are also conceivable.

According to the invention, the substrate 1 forms a reservoir part 10 and an action part 11, the two parts being joined together at a folding line AA, realized in the substrate 1 in the form of two windows 13, two The window 13 extends in the axis of the folding line AA. These two elongated windows 13 form a weak line through the substrate 1, so that if a push or pull is applied to the action portion 11 while the reservoir portion 10 remains fixed, the substrate 1 has to be folded along the fold line AA into Two trends.

The reservoir portion 10 forms a groove or inner groove 14 which together with the two plates 2 , 3 form a fluid reservoir 12 . As can be seen in FIGS. 1 , 2 , the support element 4 received in the groove formed by the substrate 1 blocks the groove 14 and holds the element 5 of porous material extending into the reservoir 12 . Therefore, until the blocking part 6 is removed, the inside of the reservoir 12 is sealed off from the outside.

For fixing the wafers 2 , 3 on the substrate 1 , adhesive techniques or heat welding can be used, for example. Therefore sheet body 2,3 can be fixed on the substrate 1 or be connected with substrate 1 along some lines, for example these lines can extend around groove 14 and/or around the outer contour of substrate 1, as shown in Fig. 1 See the crossed lines. The plates 2, 3 can extend over the entire substrate 1, or only extend over a part of the substrate 1. For example, the flaps 2, 3 may extend only over the reservoir portion 10 of the substrate 1, leaving the active portion 11 uncovered.

According to the invention, the reservoir 12 comprises spring means 7 for urging the sheet 2 at the action wall 21 located at the reservoir 12 as seen in FIGS. 2 , 4 . The function of the spring means 7 is to urge the action wall 21 away from the sheet 3, which of course is only possible after removing the removable part 6. The spring means 7 can also actuate the deformable action wall 21 when the removable blocking mechanism is in place and blocks the dispensing orifice 41, but to a very limited extent. But this does not prevent the deformable action wall 21 from having a completely unaesthetic appearance due to irregular deformations.

According to the invention, the spring means 7 extend inside the reservoir 12 below the action wall 21 . It is also not excluded that the action wall 21 is connected to the spring device 7 or is fixed on the spring device 7 . But this is not necessary. The spring means 7 may be an integral part of the substrate 1, as is the case with the embodiment of Figs. 1-5. For example, the shape of the spring device 7 can be a sheet extending in the reservoir. In practice, this sheet 7 is obtained when forming the groove 14 , leaving a central part connected to one edge of the groove 14 by a bridge 9 . The spring device thus extends in the recess 14 in the form of an almost island or an isthmus. But this is only an example suitable for Figs. 1-5. Other forms of spring means are of course conceivable. One of the main features is that the spring means extend within the reservoir 12 .

Since the spring means 7 is here formed directly from the substrate 1, it has the same thickness as the part of the substrate 1 surrounding it. In the absence of actuation, the spring means 7 is completely in one plane with the reservoir part 10 surrounding it. Thus, the spring means 7 do not urge the deformable wall to deform: the deformable wall 21 is therefore free of stress and can remain in a suitable aesthetic condition.

According to the invention, the spring means 7 cooperate with actuating means, here in the form of an active part 11 formed by the substrate 1 . More precisely, the leaf 7 of the spring communicates with the active part 11 via a bridge 9 connected to the active part 11 between two elongated windows 13 . Thus, the fold line AA passes between the bridge 9 and the active portion 11 of the substrate. Referring to FIG. 1 , since the long and narrow window 13 separates the action part 11 from the reservoir part 10 almost completely, it can even be said that the action part 11 is only connected to the bridge 9 . The bridge 9 constitutes in fact the only solid and rigid link between the spring means 7 and the action part 11 forming the starting means according to the invention.

Thus, turning the action part 11 along the fold line AA and keeping the reservoir part 10 fixed has the effect of turning the flap 7 and the bridge 9 in the same direction, but beyond the fold line AA due to their stiff connection as the bridge 9 is relatively rigid. However, the action part 11 drives the spring device 7 to be limited and stopped by the sheet body 2 connected with the substrate 1 very quickly. The spring device 7 deforms the sheet 2, forming the action wall 21, up to a maximum deformation state corresponding to the maximum volume of the reservoir 12. But this is only the case after removing the removable blocking mechanism 6 . When the detachable blocking mechanism 6 is still in place, the plate 7 of course acts on the action wall 21, but the action wall 21 is only deformed very slightly. The action part 11 continues to rotate around the fold line AA, creating a crease at the fold line AA between the action part 11 and the two elongated windows 13 between the bridge 9, which is indicated by reference numeral 91 in FIG. 1 . Once the crease is formed, the action part 11 can continue to be turned until the action part 11 is in contact with the reservoir part 10, as shown in FIGS. 4 and 5 . More precisely, the action portion 11 is in contact with the wafer 3 fixed on the reservoir portion 10 of the substrate 1 . Additionally, the dimensions of the action portion 11 are substantially or exactly the same as the dimensions of the reservoir portion 10 such that once fully connected, the action portion 11 moves completely under the reservoir portion 10 . If the detachable blocking mechanism 6 has been removed in advance, as shown in Fig. 3, 4, and 5 in sequence, the effect of the action part 11 rotation is to make the spring device 7 move in the reservoir 12, so that it squeezes the action wall 21 (Fig. 4 ). Once the parts 10 and 11 overlap, it is only necessary to squeeze the action wall with a finger against the spring means 7 in order to dispense a dose of fluid product (Fig. 5). Movement by rotation of the spring means 7 under the action of the action part 11 is of course possible, since air can pass through the dispensing hole 41 into the reservoir 12 as soon as it is released from the removable blocking mechanism 6 . It is also possible to start by folding the action part 11 onto the reservoir part 10 , while the removable blocking mechanism 6 is still in place and blocks the dispensing orifice 41 . In this case, the spring means 7 are actuated in the same way against the action wall 21 but practically prevent the action wall 21 from deforming since air cannot enter the reservoir 12 . But the spring device 7 is completely against the action wall 21, so only when the detachable blocking mechanism 6 is removed, the spring device 7 can be slightly relaxed and the inner volume of the reservoir 12 can be increased by deformation of the action wall 21. Alternatively it can be seen that the spring means can be activated by actuating the trigger means shortly or very shortly before the dispenser is used. Thus, during the entire storage time of the reservoir, ie from the moment of its manufacture to the moment of its use, the spring means can be completely inactive, which leaves the unstressed active wall 21 in a suitable aesthetic condition.

The spring means 7 and the starting means 11 can also be seen as a substantially rigid foldable part which forms an inner part extending inside the reservoir 12, such as the blade 7 and the bridge 9, and a part extending outside the reservoir 12. External parts, such as action part 11. One such part can be folded at line 91 . It is conceivable, for example, to use such a foldable element in a dispenser comprising only two foil bodies joined together, ie without the substrate 1, as is the case in the example used to illustrate the invention. The foldable part can be in the shape of a reed or a small tab, one part of which goes deep into the reservoir and the other part is outside the reservoir. When the outer portion is folded over the inner portion, the moving wall formed by one of the two film bodies automatically produces a deformation. This goes back a bit to eliminating the reservoir portion 10 of the substrate 1 . Then the support part 4 is directly clamped or fixed between the two sheets.

Referring to Figures 6a and 6b there is seen a dispenser comprising other spring means, the spring directly comprising an activation means. The dispenser is formed from two wafers, or a housing and a wafer, or a housing and a plate: in the example shown, a housing 2 and a wafer 3 . As in the previous example, a support element 4 is fixed between the housing and the blade and forms an outlet 41 blocked by a reed 6 which can be pulled out. A reservoir 12 is formed between the shell 2 and the chip 3 . A spring 7' is housed in this reservoir, whose function is to actuate the housing 2 away from the sheet. The spring 7' comprises two branches 71 and 72 connected together by an elbow 70. The spring also includes a claw 73 extending from branch 71 to branch 72 . The branch 72 forms a stop 74 against which the free end of the claw can stop and remain blocked there.

In Fig. 6a the spring 7' is seen in a compressed state, with substantially parallel branches. The claw extends between the branches, its free end extending beyond the stop 74 in the direction of the bend. Claws are elastically bound and act slightly, keeping the two branches apart. If the spring is relaxed, when the reed 6 is removed, the spring will automatically relax due to the entry of air into the reservoir and the free end of the claw will be behind the stop. Therefore the spring is activated. When the spring is pressed by pressing against the housing 2 , the free end of the claw abuts against the stop 74 . When the pressure is continued, the branch 72 and the claw 73 are slightly elastically bent, as shown by the dotted line in Fig. 6b.

The spring 7' is slightly tensioned in the position of Figure 6a and more tense in the position of Figure 6b. The claw acts as a device for starting the spring. But in this embodiment, the starter is located in the reservoir and incorporated with the spring.

Reference is now made to Figures 7, 8 and 9 which illustrate a third embodiment of the present invention. This dispenser comprises a pocket 23 for a liquid or volatile fluid product, here formed by a flexible flexible sheet which is folded upon itself to form a lower sheet 233 and an upper sheet 232 . The sheets 232 and 233 are connected at a connecting fold line 230 . A blade 232 is drilled with an outlet or distribution hole 231 . The two plates 232 and 233 are fixed together in a sealed manner, fixed on their free peripheries. The sealing and fixing of the two pieces can be realized by heat welding. Since the sheets 232 and 233 are made of a deformable soft material, a volume-variable fluid reservoir is formed between the two sheets. And each sheet forms an action wall. Additionally, reservoir 12 includes a porous material element 234 capable of imbibing or immersing a liquid or volatile fluid product. Part 234 is preferably in direct contact with dispensing hole 231 . For example, the part 234 can be fixed on the sheet body 233 or the sheet body 232 .

The dispenser also includes spring means and trigger means, here in the form of an upper plate 75 and a lower plate 76 . The two panels 75 and 76 are here separate, but it is also possible to use a single panel connected by a connecting fold line like the sheets forming the pocket 23 . The upper plate 75 forms a substantially central area 7 " which, as will be seen below, will act as a return spring means. The plate 75 also has an opening 751 in which a removable blocking mechanism 6 can be located. In one aspect, the board 75 has a fold line 752 that forms an end fold 753 so that the end fold 753 can rotate around the fold line 752. As will be seen below, the fold 753 will act as an actuating means in the form of a lateral support means. The folded part 753 is also provided with a small locking spring 754, the function of which will be explained below.

The lower plate 76 may also form a return spring 7 ″, eg in its central part. In addition, the lower plate 76 has a window 764 for receiving the locking spring 754 of the upper plate 75 .

Plates 75 and 76 are intended to be secured together at their perimeters, except at the folded-back portion 753 corresponding to window 764 . Heat welding is therefore performed on the three sides of the U-shape formed by the two plates. A casing is thus obtained that is sealed on three sides and is open on the side forming the hinged fold 753 . The soft bag 23 is located between the two boards 75 and 76, within the jacket formed by the two boards together. The dispensing hole 231 is located at the center of the opening 751 . Accordingly, a removable plugging mechanism may be located in opening 751 to plug dispensing hole 231 in a sealed manner. Pocket 23 can be fixed in the casing that two boards form.

As shown in FIGS. 7 and 8 , when the folded portion 753 is in the same plane as other parts of the board 75 , the board 75 is substantially parallel to the board 76 , and the soft bag 23 is inserted between the boards 75 and 76 . The soft bag 23 is only filled with very little fluid product, so that it can have a particularly flat shape. Thus, when the pocket 23 is located between the two plates 75 and 76, it produces only a small thickness, so that the plates 75, 76 appear to overlap and there is nothing between them. This is shown in Figure 8. The overall thickness of the dispenser may be about 2-3 mm. This thickness corresponds substantially to the cumulative thickness of the two plates 75 and 76 , the two sheets 232 and 233 and the part 234 of porous material. The dispenser is then in an appropriate resting state for its transport and storage. The flaps 232 and 233 of the soft bag 23 which partially form the active walls of the soft bag 23 are not subjected to any stress. Likewise, plates 75 and 76 are not under any stress.

Sheet 232 is fixed on board 75, and sheet 233 is fixed on sheet 76, except at fold line 230 and its vicinity.

To actuate the dispenser, it is only necessary to pivot the flip-over portion 753 about the hinge line 752 in the direction of the lower plate 76, as indicated by the small arrows and dotted lines in FIG. 9 . The folding line 752 is formed in a curved manner, such as an arc. Symmetrically to this, the folded-over portion forming the edge of the leaf can also be realized in a curved manner. Thus, when the folded portion 753 is turned downwardly towards the lower panel 76, the panels 75 and 76 make a curve corresponding to the fold line 752 and the free edge. Folded portion 753 hinges until its free end rests against plate 76 and its locking leaflet 754 is seated in window 764 formed in lower plate 76 . This is shown in Figure 9. At this time, the folded portion 753 is substantially perpendicular to the board 75 and the board 76 at the same time. The flip-over portion 753 is locked in place due to the reed 754 being embedded in the window 764 . For example, the folded portion 753 may be rigid. It thus constitutes lateral support means that can keep the two plates 75 and 76 apart from each other.

Since the sheet 232 is fixed on the board 75 and the sheet 233 is fixed on the board 76, the two boards are separated by the folded part 753 inserted in the lateral support to separate the two sheets 232 and 233 from each other. The inner volume of the reservoir 12 is thus increased by the entry of air through the dispensing hole 231 and the porous material part 234 . Of course, this is only possible after removing the removable blocking mechanism 6 . In fact, it is almost impossible to bend the folded-over portion 753 to the position shown in Figure 9 without first removing the blocking mechanism 6, without destroying the dispenser. The separation of the plates 75 and 76 is only possible if air can enter the reservoir 12 . According to the invention, the plates 75 and 76, especially at the formation of the spring means 7 "are made of a deformable elastic material which gives them this elastic return feature. Therefore, once the dispenser is in the 9, just can press the 7 " place of plate 75 with one finger, and keep another plate 76 at 7 " place with another finger, make dispenser action. In this embodiment, plate 75 and 76 Each of these forms the return spring means. But an embodiment is also conceivable in which only one plate forms the elastic return means, while the other plate can be completely rigid and act as a reaction surface. For example as shown in Fig. 9 In the present embodiment, the two plates 75 and 76 can be deformed at 7", the effect of doing this is to make the sheets 232 and 233 move toward each other and deform the folded portion 230. This has the effect of putting the reservoir 12 under pressure, thus forcing a mixture of air and fluid through the dispensing orifice. The fluid product is preferably impregnated in the porous material part 234 through which air contained in other parts of the reservoir passes to entrain the fluid product with the air.

Thus, it can be seen that the folded portions 753 of the transverse supports form the actuating means that can bring the plates 75 and 76 to a separated state, as they form the spring means connected with the action walls 232 and 233 of the pouch 23 .

Here the shape of the spring and the starting device is an overcoat surrounding the soft bag 23 . Embodiments are also conceivable in which the spring and activation means are in the shape of two strips or narrow sheets, one of which comprises an activation transverse support fold. The soft bag 23 is then positioned between the two straps.

It can also be seen that the actuating means, ie the folded portion 753 is formed by the plate 75 in one piece. It can also be formed in one piece from the plate 76 . It is also possible to attach a folded portion to one of the two boards.

In this embodiment, the folded portion 753 is rigid and at least one of the two plates is elastically deformable at 7”. An embodiment is also conceivable in which the folded portion 753 is elastically deformable by bending, while The two plates 75 and 76 are substantially non-deformable or rigid. In this case, the actuating means also form the spring means. The folded part and the plates can also be deformable.

Figures 10 and 11 show a variant embodiment of the dispenser of Figures 7-9. It differs from the previous embodiments in that it does not include a separate pouch containing the fluid. This dispenser includes a front panel 75' and a rear panel 76'. Plate 75' defines a dispensing hole 755 and a window 764. Panel 76' forms a fold and turn line 752 which forms an activated transverse support folded portion 753. Each of the two plates 75' and 76' forms a spring region 7". The sheets 75' and 76' are fixed together by heat welding on their peripheries, except for the edge where the folded portion 753 and the window 764 are located. Fixing It should be airtight. In fact, in this embodiment, the sheets 75' and 76' together form the fluid product reservoir 12. They may also comprise a porous material part fixed to the sheet 75' or the sheet 76' 234. In order to complete the reservoir at the folded portion 753, a hinged wall 230' is provided, and the hinged wall 230' is sealed and fixed on the plate 75' and the plate 76' simultaneously on its entire periphery. Therefore the reservoir is composed of two Plate and hinge walls 230' are formed.

Activation of this dispenser is the same as in the previous embodiment. The folded portion 753 can be bent towards the plate 76' so that the reed 754 is embedded in the window 764. Thus, the two plates 75' and 76' are separated from each other, increasing the internal volume of the reservoir 12. Of course this is only possible after removing the removable blocking mechanism 6 . It is then only necessary to squeeze the plates 75' and 76' closer to each other, thereby reducing the internal volume of the reservoir 12 and allowing the fluid product to flow out through the porous material part 234 and the dispensing hole 755.

Here the plates 75' and 76' are elastically deformable at their regions 7", but it is also conceivable that they are completely rigid and the folded-over portion 753 is elastically deformable.

Another embodiment variant of the dispenser of FIGS. 7-11 is now explained with reference to FIGS. 12 , 13a, 13b and 13c. This dispenser also includes two panels 75 ″ and 76 ″ connected to each other at a connecting fold line 756 . Thus the two plates 75" and 76" can be made from one integral piece. Panel 75" includes an opening 751 and a window 755. Panel 76" forms a folded portion 763 connected by a hinge line 762 to the rest of the panel. In the initial position, as seen in Figure 12, the folded portion 763 is folded and attached to the board 76 ". A soft bag 23 has a dispensing hole 231 and advantageously a porous material part 234. The soft bag 23 is located at Between two plates. Distributing hole 231 is positioned at opening 751 places.According to this embodiment, the opening band 62 that plays actuating device effect comprises an end 621 that is connected with turning over portion 763 and an opposite stretching end 622.Opening The band passes between these two ends at the dispensing hole 231, forming a detachable blocking mechanism 6 at the dispensing hole.Therefore the opening band 62 extends from the folded portion 763 to the dispensing hole 231; then the band forms a crease so that the strap extends over the first part of the strap. This can be seen in Figure 12. Once the board 75" is bent and secured to the board 76", only the stretched end 622 goes beyond the jacket formed by the board. Of course, the soft bag 23 The action walls are fixed to the plates 75" and 76", respectively. Before use, the dispenser is as shown in Figure 13a. When pulling the strap, grasp the strap by the stretched end 622, starting from the removable blocking mechanism 6 that removes the dispensing hole 231 This is shown in Figure 13b. Continue to pull the strap 62 to rotate the folded portion 763 around the fold line 762 until its reed 766 is located in the window 755. For example, a supplementary stretch can be used to separate the strap 62 from the folded portion 763 .Therefore a distributor identical to that of Figure 9 is obtained.

This action band 62 therefore has a double function, namely the function of removing the removable blocking mechanism and the function of starting.
