Definitions

  • the present invention is characterized in that the pot (1) comprises two shells (1 a, 1 b) articulated with respect to each other, and in that the threads of the pot (1) and of the flange ( 8) are arranged respectively outside and inside.
  • the pot can be made by molding a suitable plastic material such as polypropylene to allow the constitution of a one-piece hinge between the diametrical edges of the bottoms of the two shells.
  • FIG. 1 Partially shown in section in FIG. 1 an apparatus produced in accordance with the invention and which essentially comprises two elements, namely a pot 1 containing a cartridge 2 and a covering 3 produced in cross section in the form of an H in accordance with what is described in French patent 2,208 .087.
  • This covering 3 advantageously but not exclusively made of a molded plastic material has a transverse web 4 whose center receives a gas intake head 5 secured to a portable device (not shown) operating with liquefied gas under pressure such as butane gas , the sample being taken from the cartridge 2 as described for the first time in French patent 1,133,075.
  • the head 5 passes through a smooth hole 4a of the veil 4 and that it is provided with a lateral tab 5a immobilized relative to said veil by means of a screw 6.
  • the transverse veil 4 divides the covering 3 into two cells, the upper one 7 which at least partially encloses the device connected to the gas intake head 5 and a lower cell 8 produced in the form of a cylindrical flange, the inner face of which is provided with a thread 8a.
  • the pot 1 is advantageously but not exclusively produced by pressure molding, and preferably by injection in a plastic manner such as polypropylene. As illustrated in fig. 2 and 3 it comprises two shells 1a and 1b each having the shape of a hollow half-cylinder and which are joined at the edge of their semi-circular bottom by a radial hinge 9. Since the pot 1 is made of polypropylene, to establish the hinge 9 it is sufficient to provide at this level a thinning of the thickness of the bottoms. It is observed that this hinge does not extend over the total length of the diameter of the pot but only over approximately 2/3 of the value of this diameter.
  • each of the bottoms of the shells 1a, 1b has radial ribs 10, 11 suitable for constituting feet by means of which the pot rests on the work surface.
  • the peripheral rim of the cartridge 2 rests on a corresponding shoulder 1e of the pot 1.
  • Each shell 1 a, 1 b is provided at its free end with a thread 1 c, 1 of which is continuous when the shells 1 a and 1 b are folded against each other in a contiguous manner. It will be noted according to the invention that the pot was produced by means of two hulls articulated at their bottom so that, starting from the unfolded position of FIG.
  • the pot 1 is basically reconstituted as if it were made in one piece, its cross section being perfectly circular at its opening so that the two threads 1 c, 1 d form only one complementary to the thread 8a of the flange 8.
  • each of the shells has projections or bosses 12 capable of engaging in the depressions considered so as to angularly immobilize the cartridge 2 relative to the pot 1.
  • a relative angular movement is ensured between the central cup above the cartridge on the one hand, and the seal 5b on the other hand, in accordance with the principle explained in French patent 2,398,962.
  • the assembly constituted by the two shells comprises at least three projections 12 distributed angularly in a regular manner around the axis of the pot, while the cartridge is provided with at least three corresponding depressions 2a distributed by same way around its axis.
