Definitions

  • the present invention relates to a plug for container with neck, of the kind comprising a body which can be tightly attached to the container neck and in which is formed at least one conduit for the emptying of the container, and a valve closing said drove.
  • the present invention also relates to a container fitted with such a stopper.
  • a such a stopper is for example described in patent FR-2 687 130.
  • This known stopper consists of at least four spare parts, namely a body, a cage, a ball and a coil spring, which must be assembled together to form the plug. As a result, the manufacturing the cap is relatively complicated.
  • the patent FR-2 616 756 further describes a closure device for vial, which consists only two elements, both shaped like cap.
  • One of the two elements or inner cap in service, caps the neck of the bottle and is tightly attached to it, while the other outer element or cap covers the cap inside and can rotate relative to it around an axis coincident with the axis of the neck of the bottle.
  • a chamber is provided between the upper walls of the two caps.
  • the top wall of the cap exterior is made in the form of a thin wall so as to form an elastic membrane, and it is curved towards the top wall of the cap interior.
  • the elastic membrane In its center the elastic membrane has an orifice into which a boss formed at center of the upper side of the inner cap, of so as to seal the central opening of the membrane elastic.
  • the upper wall of the inner cap has two eccentric holes, which are formed on either side of the central boss and in which two bosses formed in corresponding position on the underside of the elastic membrane, so as to seal these two orifices.
  • the substance that enters the chamber between the upper walls of two caps can flow not only to the exterior through the central opening of the membrane elastic, but also in the annular space between the cylinder skirts of the two caps.
  • the substance that has entered this annular space is very difficult to extract from it, especially when it comes a sticky or pasty substance. It follows that this substance will stagnate between the skirts of the two caps for the duration of use of the bottle. Not only is this unhygienic, especially for food substances, but still the substance included between the skirts of the two caps can cause the two caps to stick together the other, thus making a later opening of the very difficult, if not impossible, closure device.
  • the membrane elastic deforms to the point that its curvature is reversed, that is to say that from concave it becomes convex, and stays in the convex state when the pressure is released, so that the stopper remains open. he as a result, air can get inside the bottle. This may affect good storage or sterility of the substance in the bottle.
  • the device for closure must be closed by exerting a pressure on the elastic membrane in order to put it back in its concave state. If this is done with a finger of the hand, this is unhygienic or may be dangerous if the bottle contains a substance, for example a toxic substance or corrosive, not to be touched with the fingers of the hand.
  • the patent closure device FR-2 616 756, as with the plug of patent FR-2 687 130 it is impossible to fill the bottle without having previously removed the plug or capping.
  • the valve incorporated in the cap of patent FR-2,687,130 like the elastic membrane of the sealing device of patent FR-2 616 756 authorize flow only from the inside to the outside from the bottle. Consequently, if precautions particular or binding measures are not adopted when filling the bottle, the substance of filling is in contact with the surrounding air during the entire filling period and until the plug or plugging device is in place on the neck of the bottle.
  • the object of the present invention is therefore to remedy the aforementioned disadvantages of plugs or devices of known capping described above.
  • the plug according to the invention is characterized in that the cap body has a cylindrical part intended to be engaged in the neck of the container and having in its surface cylindrical a groove which extends circumferentially on at least part of the circumference of said cylindrical part, in that the conduit comprises a first and second channel which are separated one of the other extend into the cylindrical part of the body and emerge, & one of their ends, into said groove respectively by first and second orifices spaced apart from each other in the circumferential direction of the throat, the first opening channel, to its other end, through a third orifice located in a first end surface of the body which, in use, is inside the container, the second channel emerging, at its other end, by a fourth orifice located in a second end surface of the body which, in service, is outside the container, and in that the valve is formed by a elastomeric membrane which tightly encloses the cylindrical part of the body and the surface of the throat by covering the first and second ports of the two channels and which, by its elastic deformation, allows
  • the plug according to the invention can be advantageously made in one piece by a known technique of bi-injection molding. Matter plastic intended to form the body of the cap and the elastomeric material intended to form the membrane can be injected into the mold successively or simultaneously depending on whether one or the other is used known techniques of bi-injection molding.
  • a cap can be added to the cap according to the invention.
  • the cap has a nozzle and it is rotatably mounted on the cap body in such a way that in a first position of cap rotation, the internal channel of the nozzle is in accordance with the second channel of the plug body and that in a second position of rotation of the cap, the internal channel of the nozzle is not in concordance with the second channel of the body, so that this second channel is closed by the cap.
  • the above-mentioned cap will be preferably attached to the cap when it reigns in permanently some pressure inside the container, for example when it contains a soft drink or a fluid and a gas propellant.
  • the stopper according to the invention can be used with containers with the most diverse structures and forms and containing the most diverse fluid substances, as long as the containers are fitted with a neck.
  • the plug according to the invention it is possible to use by example, as a container, a bottle or bottle, of metal, glass or plastic rigid or semi-rigid, a pocket or a bladder in one flexible material, etc.
  • the cap and its cap can be mounted on a container whose interior volume may vary by a corresponding value at the nominal capacity of the container at a value almost zero.
  • variable volume container can be for example constituted by a pocket or a bladder in flexible plastic or in a bottle, the body is shaped like a bellows compressible and extendable in the longitudinal direction of the bottle, such as the bottle described in the patent application in France filed the same day that this patent application, in the name of the same Applicant, and entitled: "volume bottle plastic variable ".
  • the cap according to the invention is mounted on such a volume container variable, put beforehand in a state where its volume inside is nil, the container can then be filled to through the plug channels without the substance introduced into the container is in contact with air surrounding, and the container can then be emptied without air enters the container. This is particularly advantageous for good preservation of the substance in the container and / or when it must maintain a high degree of sterilization.
  • the plug 1 shown in Figures 1 to 6 is consisting of a plastic body, for example a polyurethane having a Shore A hardness of between 80 and 120.
  • the body of the plug 1 comprises a cylindrical part the and a spherical head 1b molded in one piece.
  • the center of the spherical head 1b is located on the axis 10 of the cylindrical part 1a.
  • the cylindrical part 1a of the body is intended to be engaged in the neck 2a of a container 2 (FIG. 1) and its diameter is therefore dimensioned accordingly.
  • a groove 3 is formed in the peripheral surface of the cylindrical part 1a. In the example of realization shown, the groove 3 extends all around the part cylindrical 1a, but it could only extend over part of the circumference of the part cylindrical 1a.
  • a first channel 4 is formed in the part cylindrical 1a and opens at one end into the groove 3 through an orifice 4a and, at its other end, in the lower end face 1c of the body of the plug by another orifice 4b.
  • a second channel 5 is formed in the body of the plug 1.
  • the second channel extends obliquely in the cylindrical part la and in the spherical head 1b and it opens, at one end, into the groove 3 through an orifice 5a and, at its other end, in the outer surface of the spherical head 1b by an orifice 5b.
  • the holes 4a and 5a are spaced apart on the other in the circumferential direction of the groove 3, as shown in Figures 1 and 2.
  • la groove 3 could extend over an arc of a circle whose length corresponds to the angular distance between the two orifices 4a and 5a.
  • Port 5b of channel 5 is preferably located in the upper half of the head spherical 1b and is not on axis 10 of the the cylindrical part of the cap body.
  • the cylindrical part 1a of the body of the plug, covered with the membrane 6, has an outside diameter very slightly larger than the inside diameter of the neck 2a of container 2 ( Figure 1), so that the plug 1 can be fixed to the container 2 by jamming of its cylindrical part 1a in the neck 2a.
  • the cap could have a skirt cylindrical surrounding the neck 2a and fixed to it by clipping or by screwing, said cylindrical skirt is connecting in one piece to the body of the plug in the transition zone between the cylindrical part la and the ball head 1b.
  • the diaphragm 6 acts as a valve which, at rest, closes the orifices 4a and 5a.
  • the filling of container 2 with a fluid substance can be done by injecting under pressure said substance in channel 5 through port 5b.
  • the pressurized substance repels the elastic membrane 6 in the region of port 5a, which has the effect to open this hole.
  • the substance circulates in the groove 3 to the orifice 4a where it enters the channel 4, then flows into it to enter the container 2 through the orifice 4b.
  • the substance can, by elastically deforming membrane 6, follow a reverse course of the course described above, to exit the plug through orifice 5b.
  • membrane 6 resumes elastically its initial shape and again closes the orifices 4a and 5a.
  • the valve formed by the membrane 6 therefore also allows filling and emptying the container 2.
  • the fluid should follow a relatively long journey and, moreover, it must overcome the resistance opposed by the membrane 6 which tends to resiliently return to its original shape.
  • the flow of the substance through channels 4 and 5 is therefore curbed through the membrane 6. This is generally not a problem to empty the container because, most of the time, rather seek a controlled and relatively slow flow.
  • the container 2 can be filled quickly, for example in a automatic filling chain, without being forced to increase the pressure of the substance which is injected into the container.
  • the plug 1 may include a third channel 7, which extends obliquely in the spherical head 1b and in the cylindrical part of the body of the plug.
  • channel 7 opens into the face lower end 1c of the cylindrical part 1a by an orifice 7a and, at its other end, in the upper half of the outer surface of the head spherical 1b by an orifice 7b.
  • the elastic membrane 6 partially covers the lower end face lc of the cylindrical part 1a by forming a tongue 6a ( Figures 5 and 6) which closes the orifice 7a of the channel 7, but does not close the orifice 4b of the channel 4.
  • the tongue 6a of the elastic membrane 6 forms a second valve which allows flow into channel 7 only from outside of plug 1 inwards from container 2.
  • the tab 6a opposes the flow of the fluid substance a less resistance than if the substance fluid is injected into channel 5.
  • the extent of the surface of the tongue 6a which must be deformed to let the fluid coming through the channel 7 is smaller than the extent of the area of the membrane 6 to be deformed between the orifices 4a and 5a to let the fluid substance pass through channel 5 to channel 4.
  • the tongue 6a can be formed so as to have a smaller wall thickness than that of the membrane 6 in the region of the groove 3, Under these conditions, the container 2 can be filled faster through channel 7 than through channels 5 and 4.
  • the cap 1 can be fitted with a movable cap which covers the head spherical lb of the cap and which hermetically seals port 5b of channel 5 as well as port 7b of channel 7 when the latter is present.

  • Several slots 11 are formed in the edge of the cap 8. They form tabs between them 12 elastically deformable, so that the spherical head lb of plug 1 can be fitted, with snap elastic, in the spherical cavity 9 of the cap 8. After fitting the ball head 1b into the cavity 9 of the cap 8, a ball joint is formed between these elements.

  • FIGS 17 and 18 show another form of production of the plug according to the invention.
  • the plug body 1 shown in Figure 17 does not have no spherical head, but only part cylindrical 1a with a groove 3 in its surface peripheral.
  • the membrane 6 made of elastomeric material completely covers the peripheral surface of the cylindrical part 1a and preferably also its two end faces 1c and 1d, with the exception of the orifices 4b and 5b of channels 4 and 5.
  • these channels 4 and 5 extend in the cylindrical part la of the body of the plug, from its end faces, parallel to its longitudinal axis 10.
  • the orifice 5b of the channel 5 is offset from the axis 10.
  • the cap 8 is rotatably mounted on the cap body around axis 10, without possibility of axial movement by relative to the body of the cap.
  • the wall upper 8a of the cap 8 has, in its center, a cylindrical post 29, which projects axially in the cavity of the cap 8 and which is engaged in a hole blind cylindrical 31, with a diameter corresponding to that of the pin 29, formed in the body 1a of the plug 1 in the center of its upper end face 1d.
  • the hole 31 is widened in the region of its bottom, so as to form an annular shoulder 31a.
  • the free end of the tenon 29 is correspondingly widened and the tenon 29 is split longitudinally so as to form two branches which are spaced from each other and which can be elastically deformed to allow the engagement of the pin 29 in the hole 31.
  • the lengths smaller diameter portions of the tenon 29 and the hole 31 are chosen so that after engagement of the pin 29 in the hole 31, the wall upper 8a of the cap 8 is in sliding contact with the upper end face 1d of the body la from cap and that the cap 8 can rotate around axis 10, without possibility of axial movement along the axis 10, because of the shoulder 31a.
  • the cap 8 has a nozzle 13 which here protrudes on the wall 8a of the cap 8.
  • the channel 14 of the nozzle 13 extends parallel to the axis 10 and opens into the region of the upper end face 1d of the body la by an orifice 14a which is eccentric relative to the axis 10 with the same eccentricity as the orifice 5b of the channel 5.
  • the orifice 14a of the channel 14 can be brought into concordance with port 5b of channel 5, in a single position of rotation of the cap 8, as shown in figure 17. In all other positions of rotation of the cap 8, the latter hermetically seals the orifice 5b.
  • the cap 8 includes a skirt cylindrical 8b, which surrounds the neck 2a of the container 2 and which has, in its wall, at least two openings oblong 32.
  • the two openings 32 extend in the circumferential direction of the skirt 8b and, in service, they cooperate with lugs 33 projecting from the surface outside of the neck 2a of the container 2.
  • the pins 33 have, seen in section longitudinal, a triangular profile defining a shoulder 33a which cooperates with the lower edge of the corresponding opening 32 of the skirt 8b to block axially the cap 8 after its skirt 8b has been engaged around the neck 2a of the container 2.
  • the pins 33 also serve to limit the range of motion of rotation of the cap 8 around the axis 10.
  • the notch 32a is formed in a position such that when the lug 33 is engaged in this notch, the channel 14 of the nozzle 13 is in concordance with the channel 5 of the body 1a of the plug, while the notch 32b is formed in a position such that, when the lug 33 is snapped into this notch, the cover 8 closes the channel 5.
  • the nozzle 13 may have an at least partly conical shape. So, when the container 2, the shape of which can be similar to that shown in Figures 15 and 16, constitutes the reservoir of a syringe, the nozzle 13 can also serve as a tip to receive a needle syringe.
