Abstract

1. A bottle made of polyvinyl chloride or of a plastic material with a comparable rigidity, comprising a body whose lateral wall is capable of being compressed in turns to produce small jets of liquids, characterised in that the said body has on its side wall, at least one fold extending substantially parallel to the axis of the bottle without leading either into the wall of the bottom of the bottle or into the upper side of the body of the bottle, the said fold (8) forming a reinforcement and the remaining zone (9) of the lateral wall forming a relatively soft portion which may be deformed manually.

Description

BOTTLE WITH FOLDING OR FLEXIBLE PART (S).

  We know that a very large number of bottles or containers

  low capacity customers are provided with a flexible wall which is alternately compressed to produce a thin jet of liquid through a small orifice

  be easily distributed and interrupted. This is the case, for example-

  ple, of bottles intended to contain a dose of hair lotion

  area to be distributed at the time of application

  evenly across the entire head of hair.

  Bottles of this kind are conveniently made of polyethylene which is an inexpensive plastic material having the desired flexibility. However, polyethylene cannot be used for the packaging of all

  liquid products. Certain products, in particular, co-

  hair polishers cannot be stored in po-

  lyethylene. The polyethylene can then be replaced by another common plastic material, inexpensive and not posing a conservation problem for the liquid substance which it is desired to condition, namely polyvinyl chloride;

  but, as we know, polyvinyl chloride is a ma-

  rigid face so that the bottles thus produced do not pre-

  feel the desired flexibility more and can no longer be compressed alternately without much effort using the

  fingers to produce small jets of liquid.

  The present invention aims to produce a bottle made of ma-

  rigid material, in particular polyvinyl chloride, the

  wall can however be easily deformed by hand. Se-

  lon the invention, on the wall of the bottle is housed at least one

  fold extending parallel to its axis and defining a reinforcement

  strong which by interrupting the periphery of the bottle body per-

  puts this last part to deform. Thus, despite the use of a rigid material, the smooth wall of the body of

  bottle can be compressed manually.

  The present invention therefore relates to a reagent bottle

  read in particular from a substantially rigid material,

  affected by the fact that the bottle body has on its wall

  lateral, at least one fold extending substantially parallel-

  ment to the axis of the bottle, the aforementioned fold defining a reinforcement allowing the remaining area of the side wall to

  form a flexible, manually deformable part.

  In a preferred embodiment, the bottle according to

  the invention comprises two substantially identical folds, symmetrical

  triques with respect to the axis of the bottle; each fold is provided in hollow on the side wall of the bottle body; it extends substantially over the entire height of the bottle body and ends on the one hand, in the vicinity of the shoulder of the body of

  bottle where the neck is connected and, on the other hand, to the neighbor-

age of the bottom of said bottle.

  Each fold advantageously has the configuration of a groove whose cross section perpendicular to the axis of the bottle, has the shape of a V; the aforementioned V-shaped groove has two planes of symmetry: on the one hand, a plane

  diametral passing through the inner edge of the groove and, further

  on the one hand, the transverse median plane of the bottle body; the

  two outer edges of each groove are not parallel-

  but have a spacing which gradually increases in

  starting from the end of the groove located on the side of the shoulder-

  ment of the bottle body to the middle of said body to then decrease gradually to the end of the groove located on the side of the bottom of the bottle; the depth of the grooves is also variable: it gradually increases

  from the end of the groove on the side of the shoulder

  lement of the bottle body to the middle of said body to then decrease gradually to the end of the

  groove located on the bottom side of the bottle.

  The bottle according to the invention is advantageously manufactured

  qué by extrusion-blowing or injection-blowing of a ma-

  plastic. It is preferably made of chloride

polyvinyl.

  The bottle according to the invention can be worn on its wall

  side label placed on a labeling machine

  to beg. Such a label must be affixed to a smooth part of the side wall outside of the fold (s). It is therefore advisable to orient the bottle properly inside the labeling machine. Thus, according to another particular feature of the bottle according to the invention, the bottom of the latter comprises externally, in its central part,

  a rib coming from molding, making it possible to orient the fla-

  con inside the labeling machine. This positions-

  ment can be performed by engagement of the aforementioned rib inside a slot of complementary shape provided on

  the bottle holder inside the labeling machine

ter.

  According to another particular feature, the neck of the bottle is

  lon the invention, has at its periphery an extra thickness

  provided, on the side of the neck edge, with a crenellated border.

  Within the aforementioned slots, nested

  slots of complementary shape made on the side wall

  inner rale of a closure cap which is fixed by

clicking on said neck.

  To better understand the purpose of this information

  vention, we will describe below, as an example purely

  Illustrative and non-limiting, an embodiment represented

tee on the attached drawing.

  In this drawing - Figure 1 is an exploded perspective view of a bottle according to the invention; FIG. 2 is a section on II-II of the bottle of FIG. 1, and

  - Figure 3 is an axial section of the lower part

  of the bottle shown in Figure 1.

  Referring to the drawing, it can be seen that a small capacity bottle has been designated by 1, which may contain, for example, a dose of hair product, that is to say, the

  quantity just required for application to the hair.

  Bottle 1 is made of polyvinyl chloride. It is molded

by extrusion blow molding.

  The cylindrical body of the bottle 1, the diameter of which is small relative to the height, is connected by a shoulder

  3 to a neck 4, the latter having on its periphery, on

  about half its height, an extra thickness ending, on the side of the neck edge, by a crenellated serrated border 4a. Between the edge of the neck and the aforementioned crenellated border 4a, a peripheral groove 4b is made. A closure cap 5, made of plastic, is fixed by snapping onto the neck 4 of the bottle. It also has internally, on the side of its circular bottom a, an extra thickness, the edge 5b of which defines slots of complementary shape to the slots of the neck. The fixing of the closure capsule 5 --- is done by snap-fastening of an inner annular ring (not shown) of said capsule inside the peripheral groove 4b of the neck; in this position, the slots 5b of the closure cap are

  nested in the slots 4a of the neck. The opening of the fla-

  con is made by rotating the closure cap 5 relative to the neck 4, while its closure is obtained

  by depressing the closure cap 5 on the neck 4.

  As a variant, the neck 4 may be provided, in a conventional manner, with an external thread cooperating with the internal thread formed on the closure cap to ensure the

  fixing by screwing the latter on the neck of the fla-

  con. The neck 4 of the bottle receives a dispensing nozzle 6 provided with a central orifice 7, making it possible to reduce the flow

  of liquid dispensed from the bottle.

  The liquid distribution is done by compressing al-

  ternatively using the fingers the side wall 2 of the fla-

  con. So that the latter has the required flexibility, despite the rigidity of the plastic material in which it is made, two folds 8 are provided having the same shapes and dimensions, which are arranged symmetrically with respect to the axis of the bottle; each fold 8 extends longitudinally, along a generatrix of the cylindrical side wall 2, over substantially the entire height of said side wall; it ends on the one hand, in the upper part just near the bottom of the bottle and, on the other hand, in the lower part just at

proximity to the shoulder 3.

  Each fold 8 has the configuration of a groove which, in cross section perpendicular to the axis of the bottle, takes the form of a V. The aforementioned groove has two planes of symmetry: on the one hand, a diametral plane of the passing bottle by the inner edge 8a of the groove and, on the other hand, the plane

  transverse median of the bottle body.

  According to another characteristic, the two outer edges

  8b lines which border the furrow are not parallel:

  their spacing gradually increases from the former

  end of the furrow located near the shoulder 3 up to

  that in the middle of the bottle body where it reaches its maximum value

  mum to then decrease gradually until the extremi-

  tee of the furrow placed near the bottom of the bottle.

  The depth of the two grooves varies in the same way.

  lesson: it gradually grows from the end of the sil-

  lon located near shoulder 3 to decrease

  follow gradually until the end of the groove located at

near the bottom of the bottle.

  Thanks to this configuration, the body of the bottle comprises

  te two rigid parts 8 disposed between two parts

  flat and smooth 9 (Figure 2); the two flexible and smooth parts 9 have maximum flexibility in the middle of the body of the bottle, in the area where the groove is the widest and the

deeper.

  By pressing on the flexible and smooth parts 9 of the

  bottle body, the user causes their flattening.

  It is observed that the presence of the two grooves, of partial form

  full, gives the bottle the desired flexibility. We ob-

  also serve that by pressing on the grooves 8, the

  smooth and flexible parts 9 of the bottle also deform.

  Therefore, there is no need to exercise pressure.

  sion at a specific location on the bottle body; whatever the support zone, a deformation of the wall of the

  bottle body, allowing in all cases the dispensing

  tion in the form of small jets, of the liquid contained in the bottle. An outer rib 11, substantially rectilinear, is provided in relief in the concave curved central part of the

  bottom 10 of the bottle. It extends significantly, in this example

  ple, perpendicular to the axial plane passing through the two edges 8a, of the two grooves. It allows, on a labeling machine, to position a label on one of the parts

flexible and smooth 9 of the bottle.

  It is understood that the embodiment below

  above described is in no way limiting and may give rise to

  all desirable modifications without departing from this from the

dre of the invention.
