Description

1 -

Closed container for single use.

  The present invention relates to a container provided with

  of a pouring member closed by a stopper, such as

  preferably a plastic bottle or bottle for single use and intended to contain a unit dose of a liquid dangerous to health, such as a liquid

of caustic.

  It is known that cleaning liquids such as water

  bleach are caustic products all the more -

  dangerous that they are very concentrated, this concentration

  to allow them to be contained in

  low volume ballads To avoid accidents,

  these products should not be stored

  cleaning in open containers and

  use the dose contained in the closed container completely at one time To obtain a household bleach solution, use a dose of concentrated bleach of 250 ml at 48 degrees.

  chlorometrically with 750 ml of water to obtain a

  bleach at 12 degrees chlorometric, the concentration of which is suitable for household use

  present, these unit doses of liquid product

  concentrated tick are contained in cartons or flasks

  soft plastics whose handling is different

  if not dangerous from their opening up to their

complete emptying.

  The present invention eliminates the drawbacks

  mentioned and aims at a container of the type indicated at the beginning which presents a good maneuverability and encourages the user to consume in one go the whole dose of

  liquid contained in the container.

  This object is achieved according to the invention in that the container comprises a rigid neck as a pouring member, a bottom at least semirigid and side walls at least semi-rigid, the parts 2 of the bottom wall are inclined relative to the axis of the neck and the container by an angle sufficient for said container to be able to stand in the upright position, the plug having, in a manner known per se, a closing wall extended towards the bottom by a lateral skirt, is itself destructible and fixed from

  tightly on the free edge of the neck-through

  the rear or lower extremity of the

  Side pe, lower end permanently fixed on said neck edge It is advantageous to provide between its lower end and the closure wall, the side skirt comprises a closed annular band

  equipped with a grip tongue and relives to the

  lower and to the upper part of the skirt or the closure wall by annular zones of weakening allowing the destruction of the cap

  and the tearing of the skirt by pulling on the tongue

watch for prehension.

  Thanks to this design, the container or bottle can also be handled with all the required safety

  during its emptying and because the cork is

  truit it can not be reused after the opening of the container and also because said container does not hold

  standing, the user is encouraged to use the

  held whole of the container and to dispose of it immediately

after emptying.

  Other important characteristics and advantages of

  the invention will emerge from the following description of

  several embodiments of a compliant container

  to the invention, description made with reference to

  appended sin in which: Figure I is a schematic side elevational view of a closed container in a supine position according to the invention;

  FIG. 2 is a side view of a vertical section

  3- wedge through the container along the line II-II of the figure; Figure 3 is a schematic side view of a variant of the bottom of the container; FIG. 4 is a front view of the stopper of the container closed in the prone position; FIG. 5 is a view of an axial section through the stopper and the neck of the receptacle along the line VV of FIG. 4, and FIG. is a view of a cross-section

  of the cap along the line VI-VI of FIG.

  As can be seen in the drawing, the

  unit dose I such as a small bottle or bottle

  con is preferably made of plastic by

  for example, by means of an extrusion molding operation

  flage or injection-sbufflage, this plastic being imper-

  air-tight I container includes asor

  the pourer a neck 2 which is rigid and which

  vase towards the rear, that is to say towards the bottom, to connect to the side walls 3 which are at least semi-rigid, if not rigid and which end with the bottom 4 which, for its part, is preferably rigid and at least semi-rigid and has parts

  bottom 4 a, 4 b etc sufficiently inclined by

  port to the axis 5 of the container I or its neck 2 so that at no filling state (full, empty, almost empty, semi-filled) the container can not stand, that is to say in a position in which the axis 5 is vertical The generatrices of the side walls 3 may be parallel to the axis of the neck 2 and the bottle 1, but in order to encourage the user to keep no remains of the contents of the container I after the opening thereof, it is advantageous to also give the side walls a curved or curved shape 3a (see dashed line Figure 1) Cé -4- which even removes the stable position of the container 1 when it rests on flat side faces 3

  (see Figure 2) which, in some cases, are more

  particularly in order to reduce the transport volume occupied by several containers. Advantageously, the cross-section of the container 1 may be circular, oval, etc. or fit into a triangle, a rectangle, a square or any other polygon. It is also advantageous to provide a bottom

  curved 4 having a plurality of curved bottom portions

  4a, 4b, 4c, 4d which converge towards the axis 5 At each surface point, for example 6, of the curved bottom 4, it is possible to

  associate a tangent 7 which is situated in a plane

  diai comprising the axis-5 and which includes with said axis 5 an angle α or O preferably between 15 and 75 or between 105 and 165, these angles being in any case

  90and sufficient to prevent reconciliation

  1 can stand up can also

  provide a flat bottom-4 inclined relative to the axis 5-

an angle acou B (see Figure 3).

  The end-free of the rigid neck 2 is closed by

  a destructible plug 8 which has the particularity

  to be fixed permanently on the edge 2a of the neck 2.

  The destructible plug 8 which has a section

  similar to that of the neck 2, for example

  circular, oval, or polygonal pane, comprises a closure wall 8a which extends transversely to the axis 5, and may be slightly curved either outwards or preferably towards the inside of the plug and which is extended down

  that is to say towards the bottom 4) by a lateral skirt 8b whose ex-

  lower or rear end 8 c is shaped into a bead -

  provided with a groove or annular coaxial groove-8 d whose sidewalls 8 e cover the edge 2 of the neck-neck 2 The stopper 8 can also be made of a plastic material and the tight fixing of said cap 8 on the edge 2 a neck 2 can be done by gluing or welding when the bottle and the cap are -5-

made of thermoplastic material.

  From the outer face of the side skirt 8 are formed therein two annular grooves

  9,10 parallel to each other and perpendicular to the

  5 of the neck 2 These annular grooves 9, 10 are in front of annular weakening zones 11, 12 whose thickness is smaller than the normal thickness of the wall of the lateral skirt 8 and can be 8 The annular grooves 9,10 and the weakening zones 11,12 delimit in the skirt 8 a

  annular band-tear 13 which, through

  of a radial spacer 14, is connected to a gripping tab 15 extending, for a short distance, parallel to the strip 13 As

  it can be seen in figure 6, the tear tape

  13 presents in the immediate vicinity of the

  map 14, in its part covered by languet-

  grip 15, a thinning 16 facilitating

  the beginning of the tearing off of the part of

  Of course, since the plug 8 is made of a plastic material and come from molding, all the constituent elements of said plug 8 are in one piece. The thickness of the skirt and the axial width or height. of the tear strip 13 are such that the resistance to the

  traction of said band 13 is sufficient to ensure

  to overcome the tearing of the skirt 8b at the locations of the weakening zones 11, 12, that is to say the grooves 9, 10 and to prevent both the rupture of said

  band 13 to prevent the skirt portion 8 b

  After removal of the strip 13 from the wall 8, it can not serve as a stopper, it is advantageous to

  provide the second weakening zone -12 to the

  Immediate winding of the edge of the shutter wall 8 a.

  Thanks to the invention, the opening of the container 1 - 6 is extremely simple and safe and must be done by the destruction of the cap 8 Simply pull on the grip tab 15 so as to rotate around the neck 2 from its free end towards the spacer 14, it will be seen that the tear strip 13 will separate completely from the lower part of the skirt 8, the lower part comprising the bead 8c and fixed

  permanently on the neck 2, and that in a short time

  3 it will remain attached to the upper part of the skirt 8 or to the closure wall 8a, which

  avoid any contact of the fingers with the latter.

  The different embodiments previously

  described may be subject to a number of changes

  without going beyond the scope of the pro-

  tion defined by the appended claims.

  in particular understood that the structure of the cap used in combination with the container may be different from that described above, provided that the skirt of the cap is made permanently attached to the neck of the container and comprises a tear-strip which, once The container described above may be provided with a stopper as described in the patent application entitled "Destructible Stopper".
