Definitions
- the invention relates to containers dispensing liquid to pasty products in doses of given volume or given mass (aerosol spray, cream or gel nuts) using a pump and a dip tube.
- Such dispensing containers comprise a container body intended to contain the product to be dispensed and a pump body covering an opening formed in the container body for filling said container body.
- JP 10 305 884 discloses such pump containers which make it possible to exhaust almost all of the fluid product which they contain.
- the container body includes a cylindrical side wall and a bottom for providing a stable seat to said container body.
- the bottom has a conical inner surface that will narrow from top to bottom.
- the lower end of the dip tube suction pipe of the pump body
- the product that remains last is in the deepest part of the bottom, surrounding the open end of the dip tube, and can thus be sucked out through the dip tube using a action performed on the pump.
- JP 10305884 is perfectly satisfactory because it makes it possible to use almost all of the product contained.
- the false return of the product is not always as good in some applications, especially when it is important to dispense constant quantities of product using the pump.
- This case is frequently encountered in containers for pharmaceutical products where the product must be delivered in a controlled quantity. These include the dispenser of drugs by inhalation of aerosols in the mouth and respiratory tract (treatment of asthma, throat, etc.).
- Applications FR 0929 189, FR 1 035086 and EP 0972504 illustrate containers having a well provided in the center of the bottom intended to collect the last drops of the liquid product contained in said container.
- Applications FR 2578426 and US 4470256 illustrate containers fitted with a spraying device comprising a pump supplied by a dip tube, the open end of which is placed inside the central well formed on the bottom of the container.
- the containers offered by the prior art have a shape that is easy to obtain by molding.
- FR 0 929 189 and US 4 470 526 no indication concerning the material of the container is provided.
- EP 0972504 and FR 2578426, the containers are glass bottles.
- Such containers have the disadvantage of being fairly heavy and easily breakable and of allowing light to pass through, which risks degrading the packaged products (pharmaceutical products in particular).
- Such containers could also be made of plastic, but in this case the wall of the container has a poor barrier to the diffusion of the aromas contained in the product or of the outside ambient air which risks contaminating the packaged product.
- German utility model DE 91 08 906 presents a metal container made up of several parts, one of them being an internal metal container provided with a central well.
- This container has the drawback of requiring the assembly of several parts and of having an unstable seat (the bottom of the cylindrical skirt 14) whose lightness does not compensate for the weight of the distribution system attached to the top of the container.
- the Applicant has therefore sought to develop a pump dispenser which is light and unbreakable, which has a high rate of restitution and which makes it possible to distribute, with doses at guaranteed constant volume (or guaranteed constant mass), a product which will have has been preserved from air and ambient light and / or which will have retained its fragrances and aromas throughout the duration of its storage.
- a first object according to the invention is a pump container comprising a container body and a pump body, the container body comprising a cylindrical side wall and a bottom ensuring a stable seat to said container body, the pump body comprising a pump and a dip tube, the internal surface of the bottom comprising a well whose position, section and height are such that open end of the plunger tube esf located in the volume occupied by this well, characterized in that said container body is made in one piece and in that it is made of aluminum alloy.
- the container body is made in one piece and, so as to ensure a stable seat, it has a thick bottom relative to the cylindrical side wall.
- the average thickness is more than three times that of the cylindrical side wall.
- it is greater than ten times said thickness.
- the container body is advantageously obtained from an aluminum alloy blank itself obtained by impact spinning
- the well located on the bottom is a cavity intended to collect by gravity the liquid contained in the housing so that it remains always filled until the end of use of the container, even when the rest of said container is empty.
- the open end of the dip tube is in the volume occupied by this well, preferably near the bottom of this well. ⁇ More precisely, the depth of this well is such that the open end of the dip tube is advantageously at a distance at most equal to half the diameter of the dip tube.
- the open end of the dip tube has one or more notches.
- the rest of the internal surface of the bottom of the container has a shape converging towards this well, so that the liquid is attracted to the well at the end of use.
- the slope must not be too high to keep a small footprint but it must be sufficient so that no loss feeding does not occur when the container is handled under normal conditions, i.e. in a substantially vertical position.
- the rest of the bottom advantageously has the shape of a truncated cone whose angle in the center is between 130 and 179 °, preferably between 140 ° and 175 °, or better still between 150 and 170 °. In this way, even if the housing is slightly tilted during use, the well can still be filled with the liquid to be dispensed.
- the well is a cavity in two parts, the lower part having a substantially vertical side wall, that is to say inclined less than 20 ° relative to the axis of the container, the upper part having a more strongly inclined wall, that is to say between 40 and 60 ° relative to said axis.
- the well can thus be in the form of a double truncated cone having apex angles respectively less than 40 ° and between 80 and 120 °.
- the height of the well is preferably determined so that it is greater than the critical height from which the pump priming occurs.
- the Applicant has in fact found that, whatever the container used, said defusing of the pump is due to the creation, during a press on the pump, of a vortex in the liquid with suction effect of the air above the liquid level. It is the suction of air during pressing that makes the volume of liquid distributed random.
- This defusing occurs when the liquid remaining in the container occupies a residual volume whose height is less than a critical height, depending on the vacuum created by the pump, the viscosity of the product and, to a lesser extent, the geometry of the end of the dip tube.
- this critical height is close to 4 mm, which shows that, with a diameter of 25 mm, the last 2 milliliters of liquid cannot be dispensed in constant doses of 50 ⁇ l guaranteed.
- this critical height depends little on the section of the column of liquid which surrounds the open end of the dip tube.
- the well must have a greater volume than that of the end of the dip tube that it is intended to accommodate.
- this volume can be as small as possible, provided that the liquid can easily flow there and that the end of the dip tube can be easily positioned in the well.
- the difference between said volume of the well and that of the part of the dip tube situated in the well therefore corresponds to a minimum number of doses to be dispensed, this number preferably being less than 10, or better still, less than 5.
- the well has an axisymmetric shape, more particularly cylindrical, frustoconical (having a small half-angle in the center) or, preferably, with a double truncated cone, which facilitates the positioning of the open end of the tube plunger inside the well while limiting the volume of said well. It is generally located in the center of the bottom of the container but it can be placed in any other place. In such a case, a straight dip tube will advantageously be chosen to facilitate the conditions of assembly of the container body and the pump body, the axis of the well having to coincide with the axis of the pump and of the dip tube.
- a second object according to the invention is the container body itself intended to be assembled with a pump body to obtain the pump dispenser container, first object of the invention, described above.
- a third object according to the invention is a method for obtaining the container body according to the invention. This process is described in detail in the following example.
- Figure 1 illustrates a container body according to the invention, made in one piece and having a thick bottom.
- FIG. 2 illustrates a spun cylindrical blank used for the manufacture of the container body according to the invention, maintained fitted around a swab between two manufacturing stages separating the spinning stage from that of the buffering enabling the end to be produced. open from the body of the container (obtaining the neck and the rolled edge).
- Figure 3 illustrates another container body according to the invention, having a doubly frustoconical well. This shape facilitates the placement of the dip tube in the well while ensuring a constant distribution of the product until the said container is almost completely empty (typically, only the last three pressed do not have a volume equal to the volume constant guaranteed).
- Example 1 Dispenser with one-piece container body ( Figures 1 and 2)
- This dispenser is a pump container comprising a monobloc container body and a pump body, the container body comprising a cylindrical side wall and a bottom ensuring a stable seat to said container body.
- the pump body includes a pump and a dip tube.
- the internal surface of the bottom comprises a well whose position, section and height are such that the open end of the dip tube is located in the volume occupied by this well.
- Said container is made of aluminum alloy. It is light and it lends itself to economically advantageous shaping conditions - rear extrusion by impact spinning then buffering. In addition, it has the advantage over glass of being unbreakable and of preserving the product from light and the advantage over any plastic material of offering an excellent barrier to the diffusion of the aromas contained in the product or outside ambient air likely to contaminate the product.
- Figure 1 illustrates a container body 10 intended to be assembled with a pump body to obtain a pump dispenser.
- the container body 10 comprises a cylindrical side wall 3 and a bottom 2 which has an O-foot 8 adjacent to the cylindrical side wall, which gives a stable seat to the container body.
- the container body 10 is produced in a single piece from a cylindrical blank 40 obtained by impact spinning from an aluminum alloy pin, typically 1050A (designation according to European standard EN 573-3).
- the bottom 2 has in its center a well 1 of frustoconical shape with a half angle at the top of 15 °.
- the internal surface 4 of the bottom 2 rests, outside the well 1, on a conical surface whose angle at the center is 160 °.
- the angles are not sharp and have fillets of several millimeters (3 in this case) to facilitate the production of the well during spinning and the evacuation of the punch after shaping.
- the blank 40 resulting from this impact spinning has a thin cylindrical wall and the bottom 2 described above.
- the blank is then confined by dabbing to make a shoulder 5 and a collar.
- the end of the neck is then buffered to produce the rolled edge 6 provided to facilitate the fixing of the pump body by crimping.
- the blank undergoes several intermediate manufacturing stages, most of which optional: pickling (intended to remove the spinning lubricant), varnishing, lacquering, printing and various thermal or UV treatments for polymerization and / or drying of inks and varnishes.
- the particular container of the example is intended to collect a pharmaceutical product for the treatment of the respiratory tract. It is coated internally with an approved varnish. Its cylindrical side wall 3 has a thickness of 0.3 mm, its outside diameter is close to 26 mm. The bottom 2 has, outside the well, a thickness varying between 4 mm and 7 mm. Under the well, this thickness is close to 1, 3 mm. The average thickness of the bottom is thus close to 5.6 mm, or more than 10 times the thickness of the cylindrical side wall. The useful volume is 14 ml and it is intended to dispense 280 doses of 50 ⁇ l of liquid.
- Well 3 frustoconical with an inlet diameter of 8 mm on purified points and high of about 4.5 mm, occupies a total volume of about 300 ⁇ l.
- the residual volume offered to the liquid is of the order of 200 ⁇ l, ie 4 pressed. Only the last four pressed on the pump do not guarantee the distribution of doses of 50 ⁇ l of product.
- the volume necessary to contain the same quantity of product should, with a half angle at the top of 50 °, be approximately 1 ml greater than that of the container according to the invention .
- the container of the prior art would contain a smaller quantity of product, corresponding to a loss of 20 pressed.
- the unusable residual volume remains greater than that caused by the well because it would correspond to 0.6 ml or 12 presses, a figure to compare with the 4 presses obtained with the container according to the invention.
- the container of this example has the other advantage of being able to accommodate a decoration and / or a text printed on its entire external surface, which is appreciable for containers containing products intended for therapeutic treatments. .
- This bottom has the advantage of giving remarkable stability to the container, the center of gravity of said container being particularly low.
- This stability is advantageous for the conditioner because it makes the conditions for filling the product easier.
- technical difficulties arise because, if the thickness of the bottom is an advantage for the conditioner and the end user, it makes the manufacture of the box more difficult, in particular its transfer between the various manufacturing stations.
- the cylindrical blank of the housing must be obtained by impact spinning by modifying the conventional lubrication conditions.
- the pins intended to be spun by impact are covered over their entire surface with a solid lubricant of the zinc stearate type.
- Such a practice can be generalized to any case having a cylindrical side wall and having a thick bottom relative to that of the cylindrical side wall, that is to say having an average thickness typically greater than three times that of said side wall. cylindrical.
- the cylindrical blank once spun, is usually transferred using a spiked chain between the optional downstream manufacturing stations.
- the blank is first transferred to the pickling (to remove the lubricant used when spinning the blank), then, optionally, to the internal varnish deposition station. It is then transferred to and in the drying device of said varnish.
- it is then transferred to a lacquering station followed by a pass through the parade in a heat treatment oven.
- it is transferred to a decor printing station and / or a varnishing station followed by a pass in the parade in or in front of a drying device (thermal or by ultraviolet) of inks or varnishes.
- the draft is usually fitted around a spike then it is driven by said spike secured to a moving chain, to go from one of these downstream manufacturing stations to the next, the spike possibly depending on the circumstances having its vertical or horizontal axis .
- the blank has a very off-center center of gravity with respect to its volume casing and therefore risks tipping out of the spike and falling during its transfer to the spike chain, especially when the spike moves with an axis kept horizontal.
- the ends of the pins are advantageously provided with a solid piece, possibly perforated, or with a brush, the piece or the brush being in the form of a diabolo, the maximum diameter of said piece or brush being slightly smaller.
- the internal diameter of the spun cylindrical blank The length of the part or of the brush is close to that of the cylindrical wall of the blank so that the cylindrical blank is held on its support.
- the swab 41 is a cylindrical brush having a diameter slightly greater than the inside diameter of the cylindrical blank 40. They are provided with bristles sufficiently fine to not scratch the internal surface of the cylindrical blank.
- the bristles are chosen from a material (silicone, tetrafluoride polymer ethylene, or any other material capable of withstanding the solvents used for degreasing and the temperatures of varnish drying or lacquer polymerization ovens).
- the counter chain acts as a movable stop and allows the cylindrical blank spun on the pin to be held in position, while eliminating the slippage between the blank and its retention. This avoids the deformations of the pins and blanks due to the significant friction that may be generated during such sliding.
- Differential lubrication of the pins, transfer of the blanks using pins provided with diabolo-shaped parts or brushes at their ends, or still their transfer using swabs and finally their maintenance using counter chains acting as movable stops can be generalized to any type of cylindrical blank having a thick bottom, that is to say a average thickness greater than three times the thickness of the cylindrical side wall.
- Example 2 Distributor with one-piece container body the bottom of which has a doubly frustoconical well (FIG. 3)
- This distributor differs from the previous one only in the shape of the well.
- Figure 3 illustrates the bottom of the body of this container.
- the bottom 2 ' has in its center a well 1' of doubly frustoconical shape with half angles at the top of 15 ° and 50 ° respectively.
- the internal surface 4 ′ of the bottom 2 ′ rests, outside the well l ′, on a conical surface whose angle at the center is 170 °. Because of the embodiment, the angles are not sharp and have fillets of several millimeters (3 and 1 mm in this case) to facilitate the making of the well during spinning and the evacuation of the punch after shaping .
- Its cylindrical side wall 3 ' has a thickness of 0.4 mm, its outside diameter is close to 26 mm.
- the bottom 2 ' has, outside the well, a thickness varying between 4 mm and 7 mm. Under the well, this thickness is close to 0.5 mm. The average thickness of the bottom is thus close to 4.5 mm, or more than 10 times the thickness of the cylindrical side wall.
- the useful volume is 14 ml and it is intended to dispense 280 doses of 50 ⁇ l of liquid.
- Well V doubly frustoconical with an inlet diameter of 11 mm on purified points. About 4 mm high, it occupies a total volume of around 300 ⁇ l. The angles at the center of the frustoconical parts are 30 ° and 100 ° respectively.
- the residual volume offered to the liquid is of the order of 150 ⁇ l, ie 3 pressed. Only the last three pressed on the pump do not guarantee the distribution of doses of 50 ⁇ l of product.
- the user is sure to obtain the right quantity of product each time the distribution pump is pressed, apart from the last presses which are in a very limited number, typically three.
- the container according to the invention does not require the assembly of several parts. It has a low weight and has a minimal footprint compared to other alternative solutions.
