Definitions
- the present invention relates generally to tube-shaped packaging, traditionally used for the packaging of pasty products such as toothpaste, pharmaceutical products, creams and various cosmetology products, food products, adhesives, sealants, etc.
- the invention relates to a packaging tube comprising: a tubular skirt elongated in an axial direction, this skirt having a filling end closed by crushing the skirt in a transverse direction and forming a first end of the tube; and a head situated at a second end of the tube, distant from the filling end, this head itself comprising a distribution channel for the pasty product and a neck forming a radial extension of the distribution channel, the neck connecting to the skirt by a connection surface, the connection surface having, in a longitudinal plane containing the axial direction and perpendicular to the transverse direction, a determined minimum radius, and the skirt having, in a plane transverse to the axial direction and located midway between the ends of the tube, a determined circumference and a substantially constant thickness.
- a tube of the type defined above is for example schematically described in patent document DE-2914370 to solve this problem.
- the solution proposed by this patent which consists in reducing the angle between the neck and the axis of the tube, is both useful and relatively effective, the adjustment of the parameter constituted by this angle does not allow solve the problem mentioned above in all cases, that is to say with tubes of various sizes, made of various materials and containing products of various viscosities.
- the invention is in this context and aims to provide an integral emptying tube to overcome the limitations and problems mentioned above.
- the tube of the invention is essentially characterized in that the ratio of the determined circumference to the minimum radius is less than twenty (this is ie less than 6. ⁇ ) and preferably at most equal to ten (that is to say, hardly more than 3. ⁇ ).
- the neck preferably has, relative to the axial direction, a maximum inclination of less than 60 degrees. In practice, it may even prove useful to give the connection surface, with respect to the axial direction, a maximum inclination at most equal to 45 degrees, or even at most equal to 30 degrees.
- the ratio of the average thickness of the neck to the average thickness of the skirt is at most equal to 2 .
- the skirt and the head are made in one piece, without connection zone. cord.
- this tube is preferably covered over its entire surface, including the head, with a protective varnish called “barrier varnish", for example deposited by projection.
- the comfort of use of the tube of the invention is further improved by choosing, for the production of the skirt and the head, an elastically stretchable material and therefore having a very satisfactory flexibility. .
- Figure 1 is a front view of a known packaging tube, shown before use
- Figure 2 is a front view of a known packaging tube, shown after use
- Figure 3 is a front view of a packaging tube according to a first embodiment of the invention, shown before use;
- Figure 4 is a front view of a packaging tube according to a first embodiment of the invention, shown after use;
- Figure 5 is a front view of a packaging tube according to a second embodiment of the invention, shown before use;
- Figure 6 is a front view of a packaging tube according to a third embodiment of the invention, shown before use.
- Figure 7 is a perspective view of the connector tube addition illustrated in figure 6.
- the invention relates generally to a pasty product packaging tube, essentially comprising a tubular skirt 1 and a head 2.
- the head 2 and the skirt 1 are made in one piece, without a connection zone.
- the skirt has an elongated shape in an axial direction XX ′ and ends in a filling end 121 which, after injection of the product to be packaged, is closed by crushing this skirt 1, optionally hot, in a transverse direction ZZ '.
- the head 2 which is located at the end 122 of the tube remote from the filling end 121, comprises a distribution channel 3 of the packaged product, and a neck 4 which forms a radial extension of the channel 3 and which is connected to the skirt 1 by a connection surface 5.
- the problem encountered in emptying, at the end of use, the tubes of the prior art is illustrated in FIGS. 1 and 2 and lies in the impossibility of crushing the head in order to make it take out the product that is still there.
- the solution traditionally adopted in the prior art consists in reducing the volume of the product which cannot be expelled from the tube at the end of use.
- the most conventional known approach has always led to the provision that the greatest slope of the neck 4 and of the connection surface 5 make, with respect to the axial direction XX ', an angle A corresponding to an inclination also important as possible and in any case equal to 60 degrees.
- the present invention which like the document DE-2914370 proceeds from the exact opposite approach and which seeks not to reduce the lost volume of packaged product, but to avoid any loss of product, recommends on the contrary to make sure, preferably, that the neckline 4 has, with respect to the axial direction XX ', a maximum inclination A of less than 60 degrees.
- connection surface 5 relative to the axial direction XX ', a maximum inclination B at most equal to 45 degrees, and even possibly at most equal to 30 degrees.
- the invention provides for associating with these preferential characteristics a particular choice of parameters relating to the general shape of the tube, making it possible to use for the manufacture of the tube materials of various deformability.
- the first parameter to take into account is the smallest radius R5 that the connection surface has
- the second parameter to be taken into account is the circumference C1 which the skirt has in a transverse plane T perpendicular to the axial direction XX 'and situated halfway between the ends 121, 122 of the tube.
- the skirt 1 also has, in any transverse plane parallel to the plane T, a local thickness that is both substantially constant and equal to or very close to the average thickness E2 that this skirt has over its entire length along l 'axis XX'.
- the invention thus provides for giving the ratio C1 / R5 of the circumference Cl to the minimum radius R5 a value less than 20 (that is to say less than 6. ⁇ ), and possibly at most equal to ten (i.e. just over 3. ⁇ ).
- the pressure comfort at the end of use of the tube can be improved by giving the skirt 1 and the neck 4 identical or very similar average thicknesses, or at least by giving the ratio from the average thickness of the neck to the average thickness of the skirt, a value at most equal to 2.
- the thickness of the tube conforms to the invention must, in particular at the neck, be small enough to ensure great flexibility of the head and may therefore become insufficient to ensure the airtightness of the tube, and more precisely the oxygen contained in the air, and to preserve the contents of the tube, it may be advisable to cover the tube with a barrier varnish on practically its entire external surface including the head 2, the distribution channel 3 can however be dispensed with in the measure in particular where it can without disadvantage have a greater thickness.
- the tube according to the invention can take a relatively complex shape, moreover likely to aim for a particular aesthetic result, it is preferable to deposit this barrier varnish by projection, and not by the passage of a roller like this. is generally practiced in the prior art.
- the invention applies in a preferred manner to the production of tubes, the skirt 1 and the head 2 of which are formed in one piece by injection of an elastically stretchable thermoplastic material in its plane of at least five percent preferably. , and possibly more than ten percent.
- the skirt can then be defined by a generator G not parallel to the axial direction XX ', the shape of the tube being thus freer than in the prior art.
