Definitions

  • the present invention relates to a capsule for closing and / or adjusting the flow of product and to a dispenser comprising a container of non-compact product and this capsule.
  • not compact is meant a liquid, viscous, pasty or even powdery product.
  • Such a closure and flow adjustment capsule is particularly suitable for the distribution of one or more widely used products such as shampoos, toothpastes, depilatories, body lotions, sunscreen preparations, antiseptics, liquid eyeshadows, or else mayonnaise or mustard.
  • cosmetic, dermopharmaceutical, food or personal hygiene products of non-compact consistency are packaged in a container closed by a removable stopper or by a dispensing capsule provided with a closing member, generally tilting.
  • a dispensing capsule provided with a closing member, generally tilting.
  • the user removes the cap or causes the opening of the closure member of the capsule.
  • Caps with opening by traction called “push-pull capsules" are also known.
  • the cap may be lost; this then causes drying or degradation of the product by the ambient air.
  • most of the closure capsules usually used do not allow the product delivery rate to be varied at will.
  • the object of the present invention is precisely a closure and flow adjustment capsule which makes it possible to remedy these drawbacks.
  • the subject of the present invention is a closure and dispensing capsule for one or more products packaged in the same container having no removable cap, the dispensing of this product being able to be controlled, by the user, by simple rotation of the capsule.
  • Another object of the invention relates to a capsule for dispensing one or more products, the flow rate of one or more products can be adjusted at will by the user.
  • the subject of the present invention is a capsule for closing and regulating the flow of one or more non-compact products contained in a container, comprising a member for closing and regulating the flow of the product, made of an elastic material, mechanically deformable in at least two directions, this member being traversed by a product distribution passage, a fixed element and an element movable in translation relative to the fixed element, the fixed and mobile elements defining said passage, the closure member being sandwiched between the fixed and movable elements, control means to cause the translational movement of the mobile element towards the fixed element, this displacement - causing progressive compression of the closure member so that the passage is gradually closed by an elastic deformation of said material.
  • the closure is caused by a displacement of said elastic material, perpendicular to the axis of the capsule, in response to a crushing of said material under the effect of an axial force exerted by the movable element on the closing device.
  • the capsule of the invention it is possible to adjust the flow rate of one or more products, according to the needs of the user and the nature of the products (low or high flow rate).
  • the capsule can be mounted on a container containing a single product.
  • the user can vary the section of the dispensing passage according to the desired flow of product and according to the viscosity of the product.
  • This arrangement also has the advantage that a single dispensing capsule can be used for packaging and dispensing products of very different viscosity, because generally the distribution of a product of high viscosity requires a section of the passage of greater distribution than a product of low viscosity.
  • one can industrially manufacture a single type of packaging regardless of the product to be packaged.
  • the capsule can be used for the distribution of a bi-product.
  • the capsule comprises a hollow central channel located inside the passage communicating with a first product, and defining a space communicating with a second product, these two products being housed in the same container, separated by an appropriate partition.
  • Such a bi-product is, for example a two-component toothpaste or any other two-component product requiring the separate storage of the components, these components having to be dispensed simultaneously during the use of the product.
  • the first component can be a basic dermatological emulsion and the second a concentrate of sun filters.
  • the user can vary the volume ratio of base emulsion / filter concentrate, so as to obtain a sunscreen composition with a variable sunscreen content.
  • the protection index can be adjusted at will by the user.
  • the channel, the fixed and movable elements preferably have a circular section and define an annular space surrounding the central channel.
  • the closure member is arranged so as to be able to reduce or even close off said space during its compression, then radial deformation.
  • the central channel is in permanent communication with the first component of the product whose flow is constant.
  • the annular space is supplied by the second component of the product, the flow of which is variable.
  • the capsule for means of indexing the flow rate of the second product, located on the fixed and mobile elements respectively.
  • the indexing means can indicate the protection index corresponding to the volume proportion of the two components distributed.
  • the fixed element advantageously comprises a thread cooperating with a complementary thread formed on the movable element, the rotation of the movable element relative to the fixed element causing the compression of the elastic member, this assembly constituting the control means.
  • the fixed element advantageously comprises a thread cooperating with a complementary thread formed on the movable element, the rotation of the movable element relative to the fixed element causing the compression of the elastic member, this assembly constituting the control means.
  • other means of variable complementary fixing of the fixed and movable elements to ensure their maintenance in a determined position can be envisaged as a notch system.
  • the element movable in rotation is advantageously a cylindrical ring comprising a compression edge cooperating with the elastic member.
  • the elastic material can be any material capable of transforming a deformation in compression into a radial deformation.
  • the elastic material is an elastomeric material chosen from the group of polyethylene, polyurethane, polyester elastomers; polyether block amides; polyvinyls; ter-polymers of ethylene, propylene and a diene (EPDM); block styrene-butadiene polymers (SEBS-SIS), silicones, natural or synthetic rubbers, for example nitrile or polybutadiene rubber.
  • elastomeric material chosen from the group of polyethylene, polyurethane, polyester elastomers; polyether block amides; polyvinyls; ter-polymers of ethylene, propylene and a diene (EPDM); block styrene-butadiene polymers (SEBS-SIS), silicones, natural or synthetic rubbers, for example nitrile or polybutadiene rubber.
  • this elastomeric material can be in the form of closed cell foam.
  • the elastic material advantageously has a Shore A hardness included in particular in the range from 20 to 80, and preferably a Shore A hardness of around 30.
  • the closure member made of this elastic material is advantageously in the form of a washer provided with a central bore.
  • the central bore of this washer is an integral part of the distribution passage.
  • This washer may have an external diameter and the orifice constituting the distribution channel has an internal diameter, such that the external diameter / internal diameter ratio is preferably around 4.
  • the washer has a thickness such that the internal diameter / thickness ratio is approximately 1.
  • FIG. 1 represents an exploded view in elevation of a closure and flow control capsule, according to a first embodiment of the invention.
  • FIG. 2 shows an axial section of the capsule of Figure 1 mounted in the closed position.
  • Figure 3 shows an axial section of the capsule of Figure 1 mounted in the open position.
  • FIG. 4 represents an axial section of a second embodiment of a capsule of the invention, this capsule serving for the simultaneous distribution of two different products, an annular distribution passage for one of the two products being capable of '' be closed, at least partially.
  • Figure 5 shows the capsule of Figure 4, in which the distribution passage of one of the two products is partially closed.
  • FIG. 6 shows, in section, the closure and flow adjustment capsule at the level of the elastic member according to the plane VI-VI of FIG. 5.
  • FIGS. 1 to 3 With reference to FIGS. 1 to 3, one can see a first embodiment of a capsule according to the invention, generally designated by the reference 1.
  • a container 2 made of flexible or semi-rigid material, comprising a cylindrical body closed by a closure cap 1 and having a longitudinal axis X.
  • This body ends in a frustoconical shoulder 22, connected to a neck cylindrical 8 of smaller diameter than that of the container body.
  • the neck 8 constitutes a fixed element.
  • This neck 8 is provided with an external thread 14.
  • the neck 8 defines a central internal passage 12 through which a product of liquid consistency, contained in the container, can flow. Between the thread 14 and the shoulder 22 is arranged an annular attachment bead 20 whose role will be described later.
  • the closure cap 1 comprises a washer 4 of elastic material which can be deformed radially and axially.
  • this washer is shown in its initial form.
  • This washer is disposed on the free end 9 of the neck 8. It is made, for example, of polybutadiene rubber.
  • This washer has substantially the same section as the neck 8. It has a closable central distribution bore 6, forming part of the central passage 12. The diameter of this bore is noted d.
  • the external diameter D of the washer 4 is such that the ratio D / d is approximately 4.
  • D is 20 mm
  • d is 5 mm
  • the thickness e of the washer is approximately 5 mm .
  • the container 2 has a volume of approximately 250 ml and contains, for example, a hair shampoo.
  • the capsule 1 further comprises a movable element 10, in the form of a cylindrical flow-adjusting ring, the top 11 of which constitutes an annular plate.
  • This plate 11 has a central opening 13 which constitutes the product dispensing orifice.
  • the washer 4 is sandwiched between the annular plate 11 and the end 9 of the neck 8.
  • the cylindrical ring 10 has an internal thread 16 (see FIGS. 2 and 3), complementary to the external thread 14 of the neck 8.
  • An annular bead internal 18 is provided on the lower edge of the ring 10, on the side facing the container; it is intended to snap under the annular bead 20.
  • the bead 20 is located on the neck away from the shoulder 22 to allow axial displacement of the ring 10 for compression or decompression of the washer 4.
  • the ring 10 cannot be unscrewed accidentally, during use.
  • the cord 20 constitutes a loosening limiter.
  • the operation of the capsule 1 is as follows: During storage, the capsule is in the position shown in FIG. 2: The ring 10 is screwed to the bottom, axially crushing the washer 4 so that the bore 6 is completely closed and the distribution of the product is impossible. When the user unscrews the ring 10 by rotation, as indicated by the arrow F, the latter moves away from its initial position. At the end of unscrewing, the capsule is in the position shown in Figure 3. In this figure, we see that the elastic washer 4 has returned to its original shape (see Figure 1) and that the bore 6 is open. By inverting the container, the product can then be dispensed.
  • Figures 4 to 6 show a second embodiment of a capsule 101 usable for dispensing a two-component product.
  • the components A and B are superimposed so that the component B is located near the neck 108.
  • the component A is therefore placed between the component B and the bottom of the container. Due to their high viscosity, components A and B do not mix.
  • the capsule 101 mounted on the container 102 is designed so that the delivery rate of the component B is variable.
  • the tubing 117 protrudes slightly from the neck 108 of the container and extends towards the inside of the latter, up to a level situated just below the interface AB.
  • Tubing 117 is wedged in the neck 108 by a plurality of radial fins 112 defining an annular space 118 filled with component B.
  • the capsule 101 comprises a washer 104 of deformable material placed on the neck 108 of the container and held in place by a flow control ring 110.
  • This ring 110 has a similar construction to that of the first embodiment, with the difference that the dispensing orifice 113 comprises a skirt 115 extending outwards and surrounding the free end 117a of the tube 117.
  • the distribution channel 106a is provided with 4 regularly spaced radial notches 106b.
  • FIG. 5 The operation of this embodiment of capsule 101 is illustrated in FIG. 5.
  • the washer 104 By partial screwing of the ring 110, the washer 104 is in a partially compressed state. Thus, its internal edges 106c are in contact with the tube 117 and only the notches 106b form passages for the component B.
  • the central channel 106a is in communication with the component A.
  • a cord C of product comes out of the orifice 113, as illustrated in FIG. 5.
  • This cord C consists essentially of component A and comprises four external longitudinal ridges formed by component B.
  • the depth of the Streaks B can be varied as a function of the compression ratio of the washer 104.
  • the flow rate of component A / component B can be adjusted at will.
  • indexing marks 124, 126 of the flow ratio of the components A and B are provided respectively on the neck 122 of the container and on the ring 110.
