Description

The present invention relates to a

  fluid carrier, which comprises a container, preferably of an elastic material such as a plastic material, provided with a dispensing spout at one of its ends, and wherein a closure member is optionally disposed, and distributor is such that the distribution

  inward compression of the sur-

  front side of the container, which is intended to be fixed

  to a support so that the dispensing spout is

ge down.

  The invention concerns a dispensing container

  fluid distribution with which the distribution is effected by the well-known pumping method: the front wall is compressed inwards then the wall returns to its position

  initially, at the end of compression, because of its elasticity

ticity.

  In addition, the invention relates to a closure member

  intended for distributors holding a liquid or a

  paste and made in a flexible material.

  When the dispenser is fixed so that the dispensing spout is directed downwards, the substance to be dispensed remains inside the container During the pumping, liquid is dispensed, but at the end of the pumping, the dispensing liquid Then interrupts a volume

  corresponding air intake must be allowed inside the container.

  to prevent an increase in the depression in the container The intake of air passing through the orifice

  inside the container is of particular importance

  for the containers according to the invention, because if this

  admission is not possible, the container flattens.

  The container does not leak because of the low depression in its upper part.

  air bubbles form a cushion of air which prevents the ear-

  liquid in the orifice or immediately above the closure member or in both locations, at the end

of distribution.

  German Patent No. 2,024,294 describes a distribution of

  a washing liquid scorer, one end of which has a threaded orifice inside which is disposed a nozzle which

  has openings and a closure rod

  threaded hole with distribution holes is mounted

  The nozzle can be closed or opened by rotating the cap This container is intended to be placed on a horizontal support, in places where ordinary soaps are available When it is desired to dispense washing liquid, take the container in your hands, turn the cap to the open position and compress

  inward the front wall of the container in order to

give some liquid.

  Finnish Patent 23,699 discloses a closure member for compressible tubes containing liquids or pastes. This closure member comprises a curved and enlarged portion made of rubber or any other similar elastic material and provided with an ejection opening. In the form of a slit, as well as a cylindrical part adjoining the curved part, however, this known closure member does not allow the entry into the container of a volume of air to replace the product dispensed, so that this organ Closing device may only be used in ordinary compressible metal tubes This closure member is not adapted to equip containers made of a flexible material

such as a plastic material.

  U.S. Patent No. 4,133,457 discloses a liquid dispensing bottle provided with a plate-shaped closure member, i.e., a flexible partition. This partition is provided in its central portion. slit-like cuts through which the liquid is dispensed, and at least one small hole for improving the flexibility of the closure wall and allowing replacement air to enter the interior of the

  container, so as to prevent flattening of the container.

  This known dispenser is therefore not hermetic and can not be used by being fixed to a vertical plane so that the dispensing spout is turned downwards. The closure plate essentially prevents the liquid from flowing rapidly to the outside the container, by

  example when it is reversed.

  The container according to the invention is characterized in that the dispensing spout is of conical shape and can be fractured or broken at predetermined points, which are arranged according to the viscosity of the liquid to be dispensed and the elasticity of the compressible container. ,

  and in that a closure member is optionally

  placed between the dispensing spout and the container, and is such that one or more channels or passages pass through this

  closure member during flow.

  Advantageously, a closure member, for example a partition made of rubber or any other elastic material and which has one or more bent cuts is disposed between the dispensing nozzle and the container The cutoff advantageously has a Y shape.

  In operation, the distributor according to

  vention is simpler and more hygienic than

  known scorers When the dispenser according to the invention is attached to a wall and is ready to be used, it is sufficient

  simply extracting fluid from the container by "pumping".

  When the hands of the user are more or less dirty, and the latter desires for example washing liquid, the wall of the container can be pressed inward by pressing the side of the hand of the user; after use,

  the container closes automatically and hermetically.

  As fluids to be dispensed, it is possible to use substances having a viscosity which varies between that of liquids and that of pasta, for example washing liquids such as liquid soaps, hand lotions, shamnooings, hair balms, shaving creams, different milks, etc.

  particularly interesting substances are sub-

  so-called thixotropic stances, which have a high viscosity at rest but behave like liquids when they are set in motion, as is the case when they are extracted from the container according to

the invention by pumping.

  Containers containing different substances to be dispensed such as washing liquids, lotions

  for hands, shampoos, etc. can be dispensed

  placed side by side above a sink In this case the different containers can be easily distinguished from each other by different colors that one

gives to the containers.

  Other features and advantages of the

  will become apparent from the following description,

  with reference to the accompanying drawings in which: Figure a is a side view of a dispenser; Figure 2 is a front view of the dispenser of Figure 1;

  scorer; Figure 6 shows a closure member; and Figures 7 to 14 show closure plates. The container 1 may be made for example of a flexible and elastic plastic material, such as a

  polyethylene or polyvinyl chloride.

  the container is provided with an adhesive surface of an adhesive material, such as a surface of a double-sided adhesive 2 by which the container can be fixed on its support so that the dispensing nozzle is directed towards the The container is intended to be attached to a wall,

for example above a washbasin.

  Preferably, the dispensing nozzle 3 comprises a nut portion and a conical nose portion which is intended to be broken at predetermined points.

  breakpoints are determined according to the visco-

  of the liquid to be dispensed and the elasticity of the

  The dispensing nozzle orifice is closed by a nozzle 5 or any other corresponding element

  made in such a way as to be suitable for the manufacture of the

tainer.

  When the container is fixed in the

  poured, that is to say, so that the spout of distribution to

  open toe 3 is directed downwards, the substance to be dis-

  In the tests, it was found that water with a viscosity of

  1 centipoise at 200 ° C. remains in the container, the diameter of which

  meter of the orifice of the dispensing spout is 1 mm Pen-

  pumping fluid is dispensed, but as soon as the

  pumping is interrupted, the fluid distribution stops.

  When fluid is pumped out of the vessel, a corresponding volume of air must be admitted into the vessel to prevent an increase in the vacuum in the vessel. The intake of air that passes through the port to the interior of the container is of great importance for the containers according to the invention with a dispensing spout

with open toe pointing down.

  In addition, the admission of air that passes through the orifice to the interior of the container is very important because, at the end of the pumping, a few drops of liquid are still distributed by the dispensing spout of the container These drops of liquid are brought back inside the container by the air bubbles which form a flow barrier

  for the liquid If a closure member 6 and / or a

  in the container between the dispensing spout and the container, the few air bubbles which enter the container after pumping form a flow barrier just above the closure member, and at the same time a flow barrier is

  formed of air bubbles in the spout of

  tribution. The diameter of the orifice of the dispensing nozzle can vary over a wide range of dimensions, for example between 0.1 and 6 mm. The diameter of this orifice increases with the viscosity and / or the surface tension of the substance to be dispensed. As already mentioned above, water having a viscosity of 1 centipoise remains in a container whose orifice diameter is

  Thus, an orifice having a diameter of 1 mm

  Also suitable for example for creams. Accordingly, for practical reasons, a diameter of 1 mm of the orifice may be chosen for all the fluids which are dispensed by a container.

according to the invention.

  The length of the spout may vary, for example it may be between 2 and 4 cm, and preferably be 3 cm.

  Breakage of the spout can also vary.

  For example, a dispensing spout having a length of 2 to 3 cm may have two to four break points which are at positions such that the inner diameter is of the order of 1.1 and 0.7 mm or about 1.25, 1 and

  0.75 mm or about 2.40, 2, 1.5 and 1 mm.

  The closure member 6 and / or the closure plate

  where appropriate, are arranged between the spout of

  tribution and the container The closure member is formed of a sleeve having a passage section 7 which is perforated

  open-pore, net-shaped

  It is made of a relatively rigid material, such as a plastic or metal. The passage section 7 is a perforated or net-shaped section or constituted by a large-pile felt or a net layer. Preferably, the closure member comprises a plastic sleeve which has a section of

  perforated passage in which the total surface of the perforations

  rations is in the order of 10 to 20% of the surface of the

  section of passage The layer with large fibers is con-

  and 1.3 mm and preferably reaches 1 mm.

  The closure member may also comprise two parts In this case, in addition to the closure member

  6, it comprises a separate closure plate 8, preferably

  The closure member is formed of a sleeve which is made of a rigid material and which may be provided with a passage section 7 perforated or open-pore, net-shaped This passage section 7 is a section perforated or net-shaped or a

  felt with large fibers or a layer of net.

  The closing member can also be

  characterized by a closing plate 8 and a sleeve 6 which is arranged at the end of the neck of the container and supports the closure plate Lemanchon is preferably provided with one or more teeth which are engaged with a

  corresponding teeth in the dispensing spout.

  The closure plate is a plate made of a flexible material, preferably rubber, having a bounce rate of between 35 and 75%, and preferably of the order of 62% (Swedish standard SIS 161 215) and a hardness between 20 and 60, but preferably of the order of 40, when measured by a hardness measuring device The material is preferably resistant

  to chemical agents The thickness of the plate is pre-

  between 0.7 and 1.3 mm.

  The cut made in the closure plate is preferably bent and has a Y shape (see figure). The length of the cut is about half the

  diameter of the closure plate and the diameter of

  of the cut is preferably equal to the diameter of the

closing plate.

0.7 and 1.3 mm.

  When the closure plate has only one

  only cut, the latter must be perfectly

  pendicular to the plane of the plate (see Figures 8 to 10).

  If the number of cuts is larger, these cuts preferably extend obliquely to the plane of

  the plate (see Figures 1 i to 14) so that each

  pure opens in one direction only, which guarantees

  a more hermetic closure of the latter.

  are cut obliquely so that some of these cuts open on one side of the closure plate

  and a part opens on the other side of the latter.

  The different denominations may also have different

bending diameters.
