  CAPSULE FOR CAPPING A CONTAINER, EQUIPPED WITH

  TILTING MEANS FOR THE DISTRIBUTION OF

  SUBSTANCE CONTAINED IN SAID CONTAINER.

  The present invention relates to a capsule S for closing a container, which is equipped with means

  for the distribution of the substance

naked in said container.

  The closure caps of this type, which adapt, for example by screwing, on the neck of bottles containing the substance to be dispensed, are used to allow a dose of

  said substance following a jet or a relative flow

  tively thin, which would not be the case if the capsule was removed due to the large section of the neck. Such capsules find application by

  example in the distribution of shampoos.

  We know a capsule of this type, which comprises a side skirt connected to a bottom in which is formed a central outlet opening, which opens into the base of a hollow area delimited by two. opposite side wings, which are perpendicular to the mean plane of the said bottom, and which

  extend from the central region of said bottom

  carrying the outlet opening to the vicinity of its border. An element through which a channel passes is pivotally mounted in this hollow zone, between a closed stopper position where it substantially occupies this hollow zone and where the outlet orifice is closed, and a raised distribution position where the above-mentioned channel is in direct communication with

  the outlet opening. For this purpose, the toggle element

  lant carries side trunnions rotating in housings opening into the wings, in the central region of the bottom. To perform this 3S tilting maneuver, the user must lift a tab protruding very slightly from the edge of the bottom of the capsule; this maneuver, which must be carried out with the nail, is not always easy. But one of

  major drawbacks of this device comes from-

  all of the fact that the distribution channel is included in the closure element of the capsule. Molding

  of this element is therefore relatively complicated.

  It has also been proposed, in accordance with American Patent No. 3,516,581, a closure cap, the bottom of which has a chimney for the outlet of the substance to be dispensed, this chimney being located in a hollow zone delimited by two facing wings and s extending substantially from one end to the other

  the bottom. This recessed area receives a low shutter

  culant having a lower liquid inlet opening bordered by a skirt fitting on the end of the aforementioned chimney, this opening constituting the entry of a channel formed in a front part of said shutter, said shutter having the same structure overall that the rocking element of the mode of

  previous achievement. The shutter has a

  rear tie constituting a lower control member

  carefully, and bearing. for this purpose, two lateral pins rotating in housings made in the two facing wings, which delimit the zone in

  hollow from the bottom of the capsule. The toggle command-

  This is done by pressing your finger on the plate

  upper part of this rear part which is a

  Far compared to the previous embodiment, however, the major drawback of this shutter is

  the same as above indicated. The realization con-

  form in U.S. Patent No. 4,645,086 is sensitive-

  similar and has the same drawbacks.

  The object of the present invention is to remedy the aforementioned drawbacks of the prior art. For this purpose, provision is made, according to the invention, for the tilting shutter to be constituted by a 6) element open along its length, said element cooperating with the part fixed on the outlet mouth of the container (or adapter), for define with it, in the opening position, an outlet channel for the substance out of the container. When the tilting shutter is closed, it is positioned on the adapter, which makes the outlet channel disappear. Thus, the outlet channel is no longer to be molded on one of the two parts of the capsule but is formed, in the open position,

  by cooperation of the adapter and the shutter.

  A subject of the present invention is therefore the new industrial product which constitutes a closure cap for a container, adapted to allow the distribution of the substance without it being necessary to remove it from the container, said capsule.

  comprising an adapter member which includes a

  chon intended to fit on the mouth of said container and connects to a bottom on which is formed a hollow area bounded by a base and by two wings facing each other, an outlet for the substance being locked in said base, said recessed area receiving a shutter member that can be tilted from a shutter position of said outlet orifice to a dispensing position in which said orifice is released, characterized in that said shutter member comprises a tubular wall having a longitudinal opening facing the bottom, said bottom comprising means complementary to said tubular wall for delimiting an outlet channel for the substance in the dispensing position

said shutter member.

  In accordance with a preferred embodiment of the invention, the base of the recessed area consists of two plates separated by a recess arranged substantially perpendicular to the axis of symmetry of said recessed area, namely

  an upper front plate, in which is

  ticked the outlet of the substance and a plate

  rear lower part, the shutter member being constituted by a base plate carrying a lower transverse tongue having a rounded edge to cooperate with said recess, said tongue sharing said shutter member between, on the one hand, a front part, comprising means

  sealing the orifice of said adapted member

  tor, as well as the tubular wall intended to constitute

  kill the outlet channel for the substance, and, on the other hand, a rear part constituting the operating flap of said tilting shutter member and carrying laterally articulation means arranged along an axis parallel to the mean line of said transverse tab, articulation means which cooperate with complementary parts carried by

said adapter member.

  In particular, the front part of the shutter member comprises, on either side of the plate

  basic, preferably two lateral wings suscep-

  tibles each penetrate into a lateral groove formed between one of the wings and the upper front plate, the two wings defining with the base plate of the front part, the tubular wall, which partially delimits the outlet channel in the position of distribution of the shutter member, the two wings being positioned completely in the lateral grooves in the closed position of the shutter member, to allow the support of the base plate on the upper front plate, but not being only partially extracted from said grooves

  in the position of distribution of the obturating member

tor.

  Likewise, provision can be made for the rear part of the shutter member to carry, on each side, a pin intended to be received in a cylindrical housing opening into each wing in line with the rear plate, in order to constitute the articulation means. said shutter member. Each of these housings can open in the upper wall of the bottom so as to have, seen in elevation, the shape of an omega. This arrangement facilitates the implementation

  place of the shutter member during assembly.

  In accordance with embodiments by-

  individuals of the closure cap according to the invention,

  the two wings are arranged in sensible planes

  bleaent parallel to the axis of the sleeve, said planes

  converging towards each other in the direction of the

  front ends of said capsule; the bottom comprises, inside the sleeve, a sealing skirt penetrating into the outlet mouth of the container; the sleeve has internal bulges arranged on an annular zone in the vicinity of its lower edge, and constituting means for snap-fastening of the adapter member under an annular ring carried by the container, said sleeve also comprising radial fins for positioning said member adapter on the end of said container; finally, the bottom externally wears an external skirt

  covering, which surrounds the sleeve.

  According to one of the embodiments, the orifice of the adapter member is bordered externally by a chimney and the means for closing said orifice are then constituted by a groove which is formed in that of the faces of the

  base plate of the front part of the obturating member

  tor, said groove sealingly receiving the bor-

  free hard chimney in position

  obturation of the shutter member.

  According to another embodiment, the orifice of the adapter member opens onto the bottom of a cylindrical cavity hollowed out perpendicularly in the upper front plate, a cavity whose director has a substantially rectangular shape whose lengths are substantially parallel to the bisector plane two lateral grooves and are arranged symmetrically with respect to this plane; the widths of the substantially rectangular director of the cavity

  are delimited by two arcs of circle, the arc of cer

  key at the front of the plate being positioned tangent

  so much to the wall in an arc forming the edge of the covering hood, the arc at

  the back of the plate coming to bear tangentially-

  lying on a line connecting the rear walls of the lateral grooves; the means for closing off the cavity is a fin, the base of which is a closed curve, said fin being formed on that of the faces of the plate of the front part of the shutter member which

  is facing the front plate and fitting in posi-

  shutter the shape of the walls of the cavity, over the entire depth of said cavity along the lengths and the rear arc, and only over a small depth along the arc

  front, so that, in the open position, the

  front tie of the fin reveals a frame-

  empty. The present invention also relates to a container closed by the closure cap such

that it has just been defined.

  To better understand the object of the invention, there will now be described, by way of purely illustrative and nonlimiting example, an embodiment shown in the accompanying drawing: In this drawing: - Figure 1 is a view in perspective of the adapter which constitutes one of the two members of the closure and dispensing capsule according to a first embodiment of the invention; - Figure 2 is an axial sectional view of the upper part of a bottle equipped with the capsule of Figure I provided with its shutter in the closed position, the cut being made in the plane of symmetry l! -ll of said adapter; FIG. 3 is a view similar to the

  symmetry- XII-XII of said adapter.

  Referring to Figures I to 10 showing a first embodiment, we see that we have designated by 1 a bottle or container equipped with a dispensing cap 2 according to the present invention; this capsule is produced in two parts, namely an adapter 3 constituting a part which is fixed on the bottle 1, and a shutter 4

  constituting a part, which is movable between a posi-

  the closure of the bottle 1 (FIG. 2) and a posi-

  distribution of the substance that the latter

contains (Figures 3 and 4).

  The bottle 1. made for example of plastic, comprises a body 5 connecting to a neck 6 by a shoulder 7. The ccl 6 carries externally, in the vicinity of the shoulder 7, an annular ring 8

for retaining the adapter 3.

  The adapter 3, also made of plastic, consists of a cylindrical sleeve 9 and a covering cover 10, which are coaxial and connected by a bottom 11. The cylindrical sleeve 9 protrudes, by its base, from the cover d '' skin 10, and it

  internally, in the part which makes sail-

  binds out of said cover 10, bulges 12, regularly spaced from one another and arranged in

  same diasmtrai plane of said sleeve 9. These bulges

  ments 12 are intended to snap under the rod 8 of the bottle 1 when the adapter 3 is placed on the latter. The sleeve 9 comprises

  internally three radial positioning fins

  ment, namely a long fin 13 arranged in a plane perpendicular to the plane of symmetry of the adapter 3, and two short fins 14, which are arranged 120 ′ from the fin 13. The fins 13 and 14 have their lower ends chamfered, which facilitates the guiding in translation of the adapter 3,

  when it is placed on the neck 6 of the bottle 1.

  The substantially circular edge of the bottom 11 is folded back to form the peripheral connection zone with the covering cover 10; the bottom 11 has, formed on its upper part, a hollow zone 15 delimited by two lateral wings 16 arranged face to face, symmetrically and obliquely

  relative to a diametrical plane of the adapter 3.

  Between the two wings 16, the bottom 11 has a

  offset 17 arranged along the axial plane perpendicular to

  cular to the aforementioned plane of symmetry, which divides said bottom I1l into an upper plate 18 in the region

  <before} o the two wings come together, and a

  lower part 19, in the Carrière region) where the two wings 16 move apart. The recess 17 has a profile substantially in a quarter circle. At their front and rear ends, the two wings 16 are

  joined together - by walls in an arc 20 and 21,

  establishing in both cases a rim of the covering cover 10 in this region. The edge 20 is

  lower height than edge 21.

  The plate 19 has a circular orifice 22 whose axis belongs to the plane of symmetry of

  adapter 3, and which is about halfway

  distance between the front flange 20 and the recess 17. By the way, as can be seen in FIGS. 4 and 6, on either side of the orifice 22, and between the front flange 20 and the vicinity of the recess 17 ,

  the wall of the plate 19 is folded, along each

  cunoe of the wings 16, to form a U-shaped groove 24

  whose role is indicated below.

  It is also formed, in the thickness of the bottom 11, between the wings 16 and the rounded zone 21 de- connection with the covering cover 10, housings 25 opening both into the upper face of the bottom 11 and. in the wings 16. Each of these housings 25 has, in the plane of the wing 16, a form of omega: it is therefore delimited by a cylindrical wall 26 opening into said wing 16 and opening in the upper part of the bottom 11, along two inclined planes 27, which flare outwards. Finally, the bottom It internally comprises a cylindrical sealing skirt 28, intended to penetrate into the mouth of the neck 6 of the bottle 1, to ensure sealing when the adapter 3 is in place on the bottle 1. The skirt 28 is connected to both the plate 18 and the plate 19, so that it has a variable height, its lower edge lying in a plane perpendicular to the axis of the sleeve 9; said lower edge is chamfered, to facilitate the establishment of

the adapter 3 on the bottle 1.

  As indicated above, the covering hood 10 is connected to the bottom 11 by a rounded zone; it has an overall shape slightly

  22 recessed in its middle part.

  The shutter member 4, which is shown in particular in Figures 8 to 10, is a part which is also obtained. simply by molding a plastic material. It consists of a

  base plate 29 intended to occupy sensitive-

  ment the recessed area 15 formed on the bottom II and having for this purpose an overall shape and dimensions corresponding thereto. Thus, the base plate 29 is delimited by two opposite oblique edges 30, which are symmetrical with respect to the longitudinal axis of said shutter 4 and which are joined at their front and rear ends by edges in a circular arc 31 and 32 respectively. The rear edge 32 is folded square to form a

short skirt 33.

  Furthermore, the distributor 4 comprises, it perpendicular to its longitudinal axis of symmetry and substantially midway between the edges 31 and 32, a short tongue 34 perpendicular to the base plate 29, oriented on the same side as the skirt 33 and extending over the entire width of said base plate 29. The tongue 34 is rounded along its edge opposite the skirt 33. The tongue 34 divides the base plate 29 into a front part 35 and a rear part 36, intended to be placed, in the mounting position of the distribution capsule 2, respectively in line with the upper plate 18 and

of the bottom plate 19.

  In its front part 35, between the edge 31 and the vicinity of the tongue 34, the base plate 29 is bordered, along its two oblique edges 30 and on the same side as the tongue 34, by two wings

  lateral 37 whose free ends are tapered.

  These wings 37 are capable of being completely housed

  in the grooves 24 of the adapter 3.

  In its rear part, the lateral edges of the base plate 29 are folded back to form two square returns 41, which constitute the extension of the skirt 33 and the height of which decreases progressively from the skirt 33 to the vicinity of the tongue 34 , o they each carry an external pin 42, sleeps the axis is perpendicular to the axis

  longitudinal de.symmetry of the shutter 4.

  The assembly of the device according to the invention is carried out in a very simple way: the adapter 3 is presented axially above the bottle 1 and

  causes it to descend along the axis Until the

  peripheral flanges 12 of the sleeve 19 snap under the peripheral ring 8; the radial fins 13 and 14 ensure the positioning of the adapter 3 on the bottle 1, and the skirt 28 ensures the sealing of the

  plugging, entering the mouth of the ccl 6.

  Next, the shutter 4 is presented flat and suitable for

  ably oriented above the adapter 3 and lowered until the pins 42 rest on the inclined planes 27; then we apply a force on the base plate 29 to penetrate the

  pins 42 in the housings 25. In this posi-

  tion, the tongue 34 is in abutment against the recess 17; the front edge 31 of the plate 29 bears against the rim 20 of the covering cover 10; the lateral wings 37 are completely housed in the grooves 24 and the outer edge of the skirt 33 is located in the vicinity of the internal edge of the rim 21

covering cover 10.

  When the capsule is put in the closed position, after dispensing, by pressing on the front part of the shutter 4, the volume of the channel 43 disappears since the plate 29 comes to bear on the plate 18: so , all the product taken out of the bottle 1 is ejected from the capsule, which avoids any risk of clogging or subsequent distribution of a

product deteriorated in air.

  All of the above and

  corresponding to Figures 1 to 10 are also found

  ment in a second embodiment shown in Figures II and 12. For this second embodiment, these elements have been numbered by adding one hundred to the reference number adopted for the

first embodiment.

  Still referring to FIGS. 1 to 10, 3S, it is noted that the orifice 22 is bordered on the outside by a cylindrical chimney 23. In the lower face of the front part 35., A blind cylindrical recess 38 is made, disposed on the axis longitudinal of the plate 29, substantially halfway between the

  border 31 and the tongue 34; around this hollow

  ment 38, is formed an annular groove 39 coaxial with it. Said groove 39 is intended to receive the cylindrical chimney 23 carried by the plate 18 in the closed position of the bottle 1: the skirt 40 formed between the recess 38 and the groove 39, ensures in the closed position, the seal between the adapter 3 and the shutter 4. During assembly, the chimney 23 is received in the groove 39 and the skirt 40 enters the mouth of said chimney for

  seal the closure.

  e10 With reference to FIGS. 11 and 12, it can be seen that the orifice 122 opens onto the bottom 150 of a cylindrical cavity 151. This cavity 151 has been formed perpendicularly to and from the upper front plate 118. Its director has a substantially rectangular shape AS, the lengths 152 of which are parallel to the bisector plane of the two lateral grooves 124 and are arranged symmetrically with respect to this plane. The widths are delimited by two arcs 153a and 153b, the arc 153a

  to the front of the plate being positioned tangential-

  ment to the wall in an arc 120 forming the edge of the cover 110, the arc 153b

  at the rear of the plate 118 coming to bear tangentially

  tielle.ent on a line connecting the ends

back of the gorges 124.

  On the underside of the front part of the shutter is formed a fin 154, the base of which is a closed curve exactly matching the shape of the walls of the cavity 151; this fin 154

  3ú is indented at the front on 3/4 of its depth.

  In the closed position, the fin 154 engages

  completely on the walls of the cavity 151 and the sub-

  stance contained in bottle 101 cannot pass.

  When we want to distribute a dose of the substance contained in the bottle 1 or 101 depending on whether we use one or the other of the embodiments

  the shutter 4 (respective-

  ment 104) on its rear part 36 (respectively 136) as indicated by the arrows in FIG. 3 respectively 12), which causes the shutter 4 (respectively 104) to tilt around the pins 42 (respectively 142). The wings 37 (respectively 137) go back into the grooves 24 (124) without however being extracted from them and the rounded part of the tongue 34 (respectively 134) slides along the recess 17 (respectively 117) formed on the bottom

  11 (respectively 111) of the adapter 3 (respectively-

ment 103).

  In the first embodiment, the outlet opening of the chimney 23 has thus been released, as shown in FIG. 3, and constituted a distribution channel 43 delimited between the shutter 4 and the front plate 18 of the adapter 3. The base plate

  29 and the lateral wings 37 form a tubular wall

  open space towards plate 18 and limited towards

the rear by the tongue 34.

  In the second embodiment, the distribution channel 155 is delimited between the shutter 104 and the bottom 150 of the cavity 151. The

  cavity 151 and fin 154 form a tubular wall

  the opening onto the wall in an arc of a circle 120

  setting up the edge of the covering hood 110 and limited

  backwards by the tongue 134.

  In this way and according to the chosen embodiment, the substance can be distributed through the channel 43 or 155 formed at the front of the capsule 2 or 102, without flowing nor backwards in the space defined between the rear part 36 or 136 of the base plate 29 or 129 and the lower plate 19 or 119, neither laterally outwards for the first embodiment, nor laterally towards the front plate 118

  for the second embodiment.
