Definitions
- the invention relates to certain flexible tubes intended for storing and dispensing liquid products of various viscosities, in the form of gels, creams or pastes, typically toothpaste or cosmetic products.
- These tubes have a head which has neither neck nor shoulder, the skirt being directly adjacent to a rigid closure.
- Said rigid stopper consists either of a nozzle fitted with a stopper or of a hinged capsule, comprising a base and a cap which pivots around a hinge attached to the base and which makes it possible to close a dispensing orifice arranged on said basis.
- US 4,470,521 presents a tube, of elongated section, elliptical or polygonal, provided with a service capsule substantially in the extension of the skirt, the hinge being placed at the periphery in the region of the major axis and the dispensing orifice being placed as far as possible from said hinge.
- this tube is molded in a single material, which does not allow to have a tube satisfactorily meeting the constraints of use: the skirt must be very flexible to allow good restitution of the product contained in the tube, but the hinge must be able to withstand numerous mechanical stresses (mainly in bending, but also in torsion and elongation) imposed during the entire use of the distributor tube.
- good resistance to fatigue is not obtained with the most flexible plastics (typically low density polyethylene) but with more rigid materials (typically polypropylene), which, moreover, are not compatible with fusion. the softer materials of the skirt, such as low density polyethylene.
- the applicant has sought to make the flexible material of the skirt coexist with the rigid material of a closure such as that represented by the French model 987300. Because it is not enough to solve the problem of compatibility in fusion. There is indeed also the problem of the rate of return of the tube thus produced: at the end of use of the tube, the user must try to expel the product which is located in the vicinity of the rigid stopper and can no longer press the skirt with as much efficiency as when the pressing takes place in the middle of the skirt.
- the Applicant has therefore sought to manufacture, under satisfactory economic conditions, a tube which comprises a head that takes up less space than conventional heads which have a shoulder and a neck, said tube nevertheless making it possible to obtain with a rigid plug directly adjacent to a skirt. flexible a refund rate higher than 85%.
- the first object of the invention is a tube provided with a head intended for fixing a stopper, second object of the invention, described below and claimed in claim 10, and of a cylindrical or prismatic skirt having a orthogonal section of any shape (elliptical, circular, polygonal, etc.) whose largest inscribed circle has a diameter D, characterized in that the head is provided with a circular cylindrical wall extending towards the inside of the tube and surrounding an orifice concentric with said inscribed circle, said orifice - which we will call hereinafter "orifice of large diameter" for simplicity - having a diameter typically between 0.5 * D and 0.9 * D, and in that it essentially occupies the interior volume of the end of the skirt over a height less than D, preferably less than D / 3.
- the closure is not directly fixed on the skirt but on a head of a particular shape, very flattened, so as to have the smallest possible footprint.
- the closure is provided with a circular skirt whose diameter is equal to or slightly greater than that of the large diameter orifice of the head. To fix this plugging on the tube, said cylindrical skirt is forced into the circular cylindrical wall surrounding the large-diameter orifice until it stops at the end of insertion.
- the open end of the closure skirt is provided with substantially irreversible fastening means such as a latching bead which relaxes elastically towards the outside as soon as it exceeds the lower end of the cylindrical wall surrounding the orifice .
- the head made of a material compatible with fusion with the material of the skirt, is sufficiently flexible so that its peripheral part, which corresponds to the junction between the head and the skirt, can undergo significant deformations while the corresponding adjacent parts of the rigid closure remains undistorted.
- Such deformability makes it possible to obtain a good rate of restitution despite the presence of the rigid plug near the end of the tube.
- the zone adjacent to the cylindrical wall which surrounds the large diameter orifice must on the other hand be little deformable since the cylindrical wall must ensure in cooperation with the cylindrical skirt of the stopper a double function: the sealing and the substantially irreversible joining.
- Said cylindrical wall must be sufficiently distant from the deformable peripheral part of the tube so that the large deformations imposed on this peripheral part lose their amplitude when they are transmitted at the level of the cylindrical wall which surrounds the orifice of large diameter. This is why the orifice said to have a large diameter has a diameter limited to 90% of the diameter of the largest inscribed circle.
- the cylindrical wall surrounding the large diameter orifice contributes to the rigidity of the head.
- the orifice must have a large diameter, typically greater than 0.5 times the diameter of the largest inscribed circle, knowing that it can be less if another means is used to stiffen said head, such as than that described below in a particular embodiment where the head is provided with bosses.
- the head occupies the interior of the volume delimited by the end of the skirt over a low height. It thus has a limited size. In this way, the quantity of material to be molded is reduced, which can have advantageous economic consequences on the material cost and even the production rates, when the head is molded and welded to the skirt simultaneously.
- the height of the of the circular cylindrical wall which surrounds; j the large diameter orifice is less than D and preferably D / 5.
- the head is also provided with a peripheral wall which extends over a small height, typically of the order of a millimeter, the skirt of the flexible tube with a slight offset inwards, so that the sidewalk 0 thus formed allows the fitting of a peripheral skirt attached to the base of the rigid closure.
- a stopper is obtained whose outer contour exactly prolongs the cylindrical or prismatic shape of the skirt. 5
- said peripheral wall is advantageously provided with notches which can accommodate the housings of the tensioning elements of the hinge.
- the tensioning elements which have a thickness close to that of the peripheral skirt of the capsule must have their attachment as low as possible on said peripheral skirt, which has the consequence of increasing locally the thickness of said peripheral skirt, at a level where it must be fitted on the peripheral wall of the head.
- the sidewalk which has a section deduced by shifting a thickness of skirt from the orthogonal section of said skirt, completes the substantially irreversible connection system of the plugging on the tube by also allowing the blocking in rotation of the plugging around the axis of the large diameter orifice.
- the head has an end wall which connects the circular cylindrical wall surrounding the large diameter orifice and the outer wall in offset offset from the skirt.
- said end wall includes bosses entering the interior volume of the end of the skirt, each boss having a bottom wall whose slope is inclined relative to the plane perpendicular to the axis of the orifice, which facilitates the flow of the product which has to converge towards the central orifice.
- the wall of bottom of these bosses is presented as a shoulder which leads the flow towards the circular cylindrical wall.
- these bosses In order to limit the size of the head, these bosses must not be too deep. They have a depth limited to D, preferably D / 3.
- Each boss also has a side wall whose shape is deduced by offset from that of the skirt and that of the circular cylindrical wall surrounding the orifice of large diameter. This offset should be as small as possible, typically less than D / 10, so as to minimize the amount of product likely to be trapped.
- these bosses also make it possible to have a more rigid head.
- the deformation differences between skirt and plugging are reduced so that the yawning effect is less apparent.
- these bosses better insulate the circular cylindrical wall surrounding the large diameter orifice in the sense that the deformations are only weakly transmitted to said wall.
- a preferred embodiment is the tube corresponding to the French model 987300: the tube has an elliptical skirt having a decor easier to read than on a circular skirt and the closure is an elliptical service capsule in the extension of the skirt which must be oriented. compared to the decor of the elliptical skirt.
- the head is provided with a positioning finger oriented towards the inside of the tube, as described in French patent application no. 0004568.
- the large diameter orifice (diameter between 0.5 and 0.9 times the minor axis of the ellipse) is here crossed by arms and partially obstructed by a veil, the whole arm and veil supporting said finger positioning.
- the veil is placed between the arms in an area straddling the major axis so that it does not obstruct the small dispensing orifice, located in the area of the minor axis.
- the bosses occupy the complementary part of the ellipse, consisting of two zones extending around the major axis, the bottom wall conforming to the shape of a shoulder, thereby improving the rate of return of the tube thus produced.
- a second object of the invention is the closure capable of being fixed in a substantially irreversible manner on the head of the tube according to the invention, characterized in that it comprises a base whose external contour matches the shape of the orthogonal section of the skirt of said tube and which is provided with a skirt - hereinafter called a large diameter skirt - whose diameter is typically between 0.5 * D and 0.9 * D, D being the diameter of the largest circle inscribed in the outer outline of the base.
- Said large diameter skirt has a height less than D, preferably less than D / 3 and is provided with means for substantially irreversible fixing of the plug on the tube festival.
- the latching bead preferably occupies the open end of the large-diameter skirt of the closure and has a frustoconical surface converging towards the inside of the tube.
- the stopper is made of a rigid material and the base of the stopper is flat to minimize the size and the weight of the upper part of the dispensing tube formed by the assembly of the stopper and the tube. flexible.
- a fastening system even if a priori it presents less economic interest, can be pointed out on other types of closures, less rigid or having a more bulky base.
- the large-diameter skirt has a cylindrical part of diameter equal to or slightly greater than that of the large-diameter orifice so that the contaci between the large-diameter skirt and the circular cylindrical wall surrounding the large-diameter orifice is perfectly waterproof, even when the skirt is strongly deformed in the vicinity of the head.
- said skirt is forced into the circular cylindrical wall surrounding the large diameter orifice until it stops at the end of insertion.
- the base of the stopper is preferably also provided with a peripheral skirt which is fitted around the sidewalk of the head of the tube according to the invention.
- This skirt makes it possible to hide the unsightly yawning due to the deformation differences between the flexible skirt and the rigid plugging.
- this peripheral skirt fitted on the sidewalk also allows immobilization in rotation of the stopper relative to the tube .
- the closure can be a service capsule.
- the hinge around which the cap pivots is composed of at least one film hinge and at least one tensioning element.
- the tensioning elements which have a thickness close to that of the peripheral skirt of the capsule, must have their attachment as low as possible on said peripheral skirt, which has the consequence of locally increasing the overall thickness of said peripheral skirt for y ⁇ mén ⁇ ger housings intended to collect said tensioning elements when the cap is folded over the base.
- the large diameter skirt belongs to the closure made in principle of a rigid material. This skirt therefore exhibits a rigid behavior liable to pose some problems at the time of fastening of the plugging at high rates on the tube head.
- the large diameter skirt is provided with flexibility slots. These flexibility slots can be quite extensive and form cavities facilitating the flow of the product towards the large-diameter orifice and therefore towards the dispensing orifice, which thus improves the false reproduction.
- these flexibility slots are on the one hand trapezoidal cavities widening downwards which facilitate the correct positioning of the large diameter skirt on the arms which pass through the large diameter orifice and d on the other hand cavities which facilitate the flow of the product towards the orifice of large diameter.
- Another object of the invention is the dispensing tube obtained by assembling the flexible tube according to the invention and the closure according to the invention.
- Figure 1 illustrates a dispensing tube according to the invention with a flexible tube according to the invention and a closure according to the invention of which only the base is shown.
- FIG. 2 illustrates a view below the flexible tube according to the invention of Figure 1
- FIG. 3 illustrates a panoramic view of the flexible tube according to the invention illustrated in FIGS. 1 and 2 and of a closure according to the invention, presented by its underside and arriving at the sight of the head of the flexible tube.
- This example corresponds to a solution proposed for producing, under acceptable economic conditions, the distributor tube presented in the French model 98 7300 published under the numbers 535 807 to 535 814 by the company L'Oréal. It goes without saying that the flexible tube head as well as the fixing / sealing skirt - known as a large diameter skirt - developed in this example are not limited to the particular shapes of the model and can be adapted to many other types of distributor tubes. .
- the tube 1 is provided with a head 10 intended for fixing a service capsule 200 - of which only the base is shown in FIG. 1 - and of an elliptical skirt 2 whose largest inscribed circle has a diameter D of 32 mm equal to the minor axis of the ellipse.
- the head 10 is provided with a circular cylindrical wall 11 extending towards the inside of the tube over a height of 3.5 mm - ie D / 9 approximately - and surrounding an orifice 15 concentric with said inscribed circle. This orifice subsequently called "large diameter orifice" has a diameter of 27 mm.
- the stopper is a service capsule 200, the base 21 of which is provided with a large diameter skirt 22.
- said large diameter skirt is forced into the circular cylindrical wall 11 surrounding the orifice. large diameter 15 until immobilized at the end of insertion.
- the open end of the large-diameter skirt 22 is provided with a latching bead 23 which elastically relaxes towards the outside as soon as it exceeds the lower end of the cylindrical wall 11 surrounding the large-diameter orifice 15.
- the latching bead 23 occupies the open end of the skirt of large diameter of the plug and has a frustoconical surface 27 converging towards the inside of the tube.
- the head is made of high density polyethylene (PE.HD), a material compatible in fusion with the materials of the multilayer skirt of general structure: PE / EMA / EVOH / EMA / PE. It is flexible enough so that its peripheral part, which corresponds to the junction between the head and the skirt, can undergo significant deformations while the corresponding adjacent parts of the service capsule, which is made of polypropylene, are not deformed. Such deformability makes it possible to obtain a good rate of restitution despite the presence of the rigid plug near the end of the tube.
- PE.HD high density polyethylene
- the head 10 essentially occupies the interior volume of the end of the skirt over a height of less than 10 mm. In this way, the quantity of material to be molded is reduced, which makes it possible to increase the production rates, since the head is injection molded and welded simultaneously to the skirt.
- the head 10 is further provided with a peripheral wall 12 which extends over a small height, typically of the order of a millimeter, the skirt 2 of the flexible tube with an offset of 0.4 mm inwards.
- the sidewalk thus formed allows the fitting of a peripheral skirt 24 attached to the base 21 of the service capsule 200.
- the wall of the peripheral skirt 24 is provided with notches 121 which can accommodate the housings 204 of the tensioning elements 203 of the hinge.
- the head 10 has an end wall which connects the circular cylindrical wall 11 surrounding the large diameter orifice 15 and the outer wall 12 in offset extension of the skirt 2. To further improve the rate of restitution.
- said end wall has bosses 13 entering the interior volume of the end of the skirt, each boss 13 having a bottom wall 14 which is presented as a shoulder which leads the flow towards the orifice of large diameter 15
- the maximum depth of these bosses 13 is 10 mm.
- Each boss 13 also has a side wall 16 whose shape is deduced by offset of the order of a millimeter from that of the skirt and that of the circular cylindrical wall surrounding the orifice of large diameter.
- the head 10 is provided with a positioning finger 17 oriented towards the inside of the tube.
- the large diameter orifice 15 is crossed by arms 18 and 18 ′ and partially obstructed by a veil 19, the arm and veil assembly supporting said positioning finger 17, which has a face resting on a substantially diametral plane, two cylindrical faces which frame said face and extend over an angle at least equal to 10 °, as well as a top face with a helical slope.
- These faces are referenced respectively 91, 92, 93 and 94 in FIG. 2 of French patent application n ° 0004568.
- the veil 19 is placed between the arms 18 and 18 'in an area straddling the major axis so that it does not obstruct the small distribution orifice 25, located in the region of the minor axis.
- the large-diameter skirt 22 has a cylindrical part of diameter equal to or slightly greater than that of the large-diameter orifice 15 so that the contact between the large-diameter skirt 22 and the circular cylindrical wall 11 surrounding the orifice large diameter 15 be perfectly ét ⁇ nche, even when the skirt is strongly deformed in the vicinity of the head.
- the large diameter skirt is provided with flexibility slots 26.
- These flexibility slots can be quite wide and form cavities facilitating the flow of the product towards the large diameter orifice 15 and therefore towards the dispensing orifice 25, this which improves the restitution rate.
- some of these flexibility slots 26 are widening trapezoidal cavities downward which facilitate the correct positioning of the large diameter skirt 22 on the arms 18 and 18 'which pass through the large orifice. diameter 15.
- Such a tube has, for a product of average viscosity between 2800 and 4000 centipoise, a rate of refund greater than 90%.
