Definitions

  • the subject of the invention is a new pressurized container, the body of which consists of the assembly of a valve body and a valve holder cup.
  • a pressurized container In the case of products distributed in a pressurized container, it is easy to prepare small packaging which respects the original formula, the criterion which the sample must satisfy is currently not respected. Indeed, a pressurized container, even a small one, requires a certain number of essential elements, which are the container body, i.e. a can in tin or aluminum, on the walls of which a varnish is deposited and on the neck of which a valve is set, by means of a valve-holder cup, as well as a means of distribution connected to the valve.
  • the technique of manufacturing pressurized cans does not make it possible to manufacture cans small enough to match the volume of a test dose, i.e. 3.5 ml to 8 ml approximately.
  • the work of crimping the metal crimping the valve holder cup, on the container body, on the one hand, and around the valve, on the other hand
  • This manufacturing constraint therefore determines the size of the valve holder cup and therefore the volume of the container, which is necessarily greater than one dose of use.
  • the invention also relates to a new pressurized device for dispensing liquid or creamy products, such as for example cosmetic products, food, pharmaceutical.
  • a pressurized device consists of a container body, on which possibly comes to fit a cover; on the neck of this container is crimped a valve via a valve holder cup, a distribution means connected to the valve is provided; the container body and the cup define a reservoir cavity; the valve consists of a valve body, a valve control rod which passes through the valve body, a seal and a return system that presses the control rod valve against the seal, the assembly being held in place by crimping the valve holder cup; the valve control rod is surmounted by a push button.
  • the container body In the container body are arranged a product to be dispensed and a means of propulsion.
  • the means of propulsion can be a compressed gas directly in contact with the product in the container body.
  • a plunger member is attached to the valve.
  • a flexible bag we are often faced with compatibility problems with the formula and strength of the material constituting the bag, which must be flexible and waterproof that time. If we use a piston to separate the gas from the product, we are faced with sealing problems along the contact surfaces between the piston and the inner wall of the container body.
  • the filling orifice of the gas must be distinct from that of the formula: the filling of the gas is often done by an orifice located at the bottom of the container, closed by a rubber stopper.
  • This configuration requires rework during manufacture: opening of the orifice filling the gas, fitting the bag or piston, fitting the plug. It is also expensive because of the complexity of the filling process: filling of the product then of the gas.
  • this device includes a high number of pieces; these parts require very fine adjustment (no screws, tightness) and are sophisticated, therefore this device is very expensive.
  • the energy storage by mechanical compression of the cellular material is done in small quantities: the user must turn the dial to store the corresponding energy about a dose of use before pressing the push button. The need to this double action makes the device complex and unattractive to the consumer hurry.
  • the bottle in which the product is contained has the shape of a bellows, also, even if it is compressed to the maximum under the action of the cellular material, this bottle cannot not empty completely and you get a low refund rate.
  • the first object of the invention is a pressurized container comprising a cup, a valve provided with a valve body, a valve control rod surmounted by a push button optionally comprising a diffusion means, a seal and a return system, the cup and the valve body cooperating with each other to form, on the one hand, a reservoir cavity capable of containing a product to be dispensed and an element propellant, on the other hand, a valve cavity, a passage being arranged between the cavity tank and valve cavity.
  • the cup and the valve body cooperate sealingly with their ends to form the body of the container.
  • the cup and the body of valve include complementary fastening elements, for example means likely to snap or complementary profiles which, once assembled, are welded together by any means known to those skilled in the art, such as, for example, rotational welding or gluing.
  • Hanging elements can also consist of complementary threads, so that one can screw the valve body and the cup tightly onto each other.
  • valve body which has, on its circumference, said hooking elements and a cup comprising a skirt outer, which has, at its end, said hooking elements complementary to those of the valve body, this cooperation defining the body of the can.
  • You can also choose a cup that has, on its circumference, hooking elements and a valve body comprising an outer skirt, which has, at its end, hooking elements complementary to those of the cup. It is also possible to use a cup and a valve body comprising each an outer skirt, the two skirts comprising hooking elements complementary.
  • valve body and the cup cooperate with each other to define a valve cavity inside the container.
  • the valve body and optionally the cup each comprise an inner skirt.
  • the inner skirts of the valve body and of the cup fit into each other on all or part of their height to delimit the valve cavity.
  • the internal diameter of the internal skirt of the cup is substantially equal to the diameter outer of the inner skirt of the valve body.
  • the upper surface of the inner skirt of the valve body advantageously comes press the seal by pressing it against the edge of the cup, which surrounds the passage valve control rod. The valve is then sealed.
  • a passage is arranged between the reservoir cavity and the valve cavity.
  • the internal skirts of the cup and of the valve body each have at least one notch, these notches being associated with a circular chamfer of one or other of the skirts, along the circumference of the surface of contact between the skirts and possibly a groove over the entire height of the surface of contact between the skirts, all of these cutouts (groove, chamfer, notches) defining said passage of the product, and possibly gas, between the reservoir cavity and the valve cavity.
  • the containers according to the invention make it possible to distribute all kinds of products: lotions, creams, mousses, milks ...
  • the container according to the invention so that the gas and the product are separated or, in the second case, mixed in a single tank cavity.
  • a reservoir cavity consisting of two cavities is provided watertight, one containing the product, the other the gas, the wall separating these two cavities being capable of transmitting the pressure of the gas from one cavity to another.
  • the wall between the two cavities can be rigid, such as a piston, or flexible, such as example a flexible pocket, a bellows or an element of cellular material.
  • the valve body and the cup are made of material thermoplastic.
  • These two elements can be made of the same material or of two different chemically compatible materials so they can be welded together or two chemically incompatible materials, assembled by screwing, gluing or snapping.
  • the materials which can be used in the present invention may include, for example, the family of polyolefins, such as polypropylene, polyethylene and copolymers of ethylene and propylene, the family of polyacetals, such as polyoxyethylene; polyethylene terephthalate can also be used, polymethyl methacrylate, the polymer used in the invention may contain fillers such as silica, glass fibers, carbon fibers. We may also consider manufacturing these elements from other materials, such as example in metal or glass.
  • the thickness of the walls of the cup and of the valve holder, and in particular of the skirts, are adapted by a person skilled in the art to resist the pressure of the propellant gas.
  • valve control rod can be of any type known to those skilled in the art, like for example an emerging rod, a female rod, whether it is displacement axial or lateral displacement, the latter type of valve also being called ⁇ tilt ⁇ .
  • the return means may in a known manner be a spring or any compressible material or elastically deformable that can be accommodated in the valve cavity.
  • the cup may include a circular groove.
  • This groove allows the use of a standard format push button which is positioned in said groove.
  • this groove gives more resistance to the cup.
  • the containers according to the invention are particularly advantageous when they are produced in the form of aerosol containers for sampling from one to a few doses use of a product, because they compensate for an absence of this type of packaging meeting the economic requirements of the market.
  • their use is not not limited to the distribution of samples: the containers according to the invention can be produced in formats of all sizes, for which the skilled person knows adapt the nature and thickness of the material to give the container resistance necessary.
  • the invention also relates to a set of pressurized containers comprising several containers as described above, each container having a cavity in the bottom of its valve body and a complementary cylindrical stud located on the lid of this container.
  • This stud and this cavity allow them to be joined together at at least two containers by fitting the stud of the first in the cavity of the second.
  • the propellant element consists of a material element closed cell alveolar, the cellular material element and the product are placed in the reservoir cavity and subjected to a permanent and uniform pressure, so that the device distributes the product when the valve is actuated.
  • uniform pressure is meant that the pressure is identical at all points in the cavity tank at a given time.
  • a container comprising such an element of cellular material avoids mixing of the gas with the product to be dispensed and avoids gas leaks.
  • the duration of use of the device is extended.
  • the pressure inside the device at the viscosity of the product to be dispensed is extended.
  • This container allows to pressurize a product, without risk of product pollution by gas and without air pollution.
  • this container has only a small number of mechanical parts in common use and its manufacture is simple, so it is little expensive. Its use is simple.
  • the container is not very fragile and does not have any risks of cells bursting due to clumsy use.
  • the means of compression is retained inside the container after complete return of the product, this container can therefore be reused several times provided that it is refilled with product.
  • a such a container thus makes it possible to save on the cost of packaging and its possible reprocessing.
  • a usable cellular material consists of a multitude cells filled with gases included in a deformable matrix, such as for example a polyolefin, elastomer or any type of thermoplastic foam, a foam of rubber, Buna, Neoprene, silicone or any other material.
  • the gas can be any gas which is compressible or liquefiable at the pressures of use, like nitrogen or it can just be air.
  • the cells When the foam is compressed, the cells are also compressed, they thus store a reserve of energy to pressurize the product. When we actuates the valve of the pressurized container, the cells expand and the product is returned.
  • the gas present in the cells is retained there and cannot escape from it. We thus avoid leakage and mixing problems with the product.
  • the cells of the foam material is never subjected to mechanical pressure, but to hydraulic pressure: inside the container, the element of cellular material is at direct contact with the product which is subjected to the same pressure as the gas. Also the risk of bursting cells is it nonexistent. This element of cellular material can therefore be used a very large number of times.
  • the element of foam material used as a means of pressurization in containers according to the invention is advantageously of shape complementary to that of the reservoir cavity, and preferably of generally cylindrical shape.
  • the cellular material element used can be made of known manner by extrusion or by cutting from a block of cellular material closed cells. To cut a cylinder of cellular material, you have to compress before cutting. By this process, after cutting and decompression, an element of cellular material with slightly lateral contours concaves, as described in EP-A-561292. When such an item is placed in a container according to the invention, product is housed between the concavity and the walls of the container. So we get a slightly lower refund rate than we can obtain with a cylinder with perfectly straight contours.
  • a cylinder of cut foam material has open cells around its edges, while an extruded cylinder does not have one. Therefore we prefer to use a cylinder of cellular material obtained by extrusion.
  • the containers according to the invention make it possible to distribute all kinds of products under form of solution, emulsion, gel: lotions, creams, self-foaming compositions, milks, gels.
  • the element of cellular material is of larger dimensions (height, diameter) to those of the reservoir cavity so that when the cavity is closed tank, we obtain a pre-compression of the element in cellular material so to have more energy available when there is little product left in the container.
