Description
[0001] The present invention relates to a gas bottle on which means
of controlling the inlet and outlet of gas are fixed, particularly
a valve unit or a pressure reducing valve assembly, possibly
equipped with a flow meter, preferably inserted in a protective
cowling also mounted on the bottle, said bottle and said protective
cowling and/or the means of controlling the inlet and outlet of gas
being covered by one or more peripheral external protective casings
consisting of one or more thicknesses, which may or may not be
preassembled, guaranteeing the gas bottle thus equipped a high
level of external cleanliness and hygiene.
[0002] Currently, bottles containing gas for medical use,
laboratory gas and industrial gas are externally painted and
generally marketed as is, that is to say with no external
protection or overlapping.
[0003] Given the immaterial nature of the contents, namely
colorless gases inside the bottle, the image of the product is
conveyed only by its container.
[0004] Now, given that the bottle is subjected during its life
cycle to numerous handlings and transport operations, both at the
premises of the manufacturer and at those of the user, the external
appearance of the bottle quickly suffers degradation giving this
recyclable packaging an appearance of mediocre quality, which gives
a devalued image of the product, particularly when the bottle
contains a medical gas, such as a gaseous drug.
[0005] In addition, the wear resulting from use and recycling of a
gas bottle over a somewhat lengthy period leads to a surface finish
which, particularly while the bottle is in storage, encourages the
retention of dust, dirt and various microorganisms and may pose
health risks. Thus, the presence of germs on the sides of gas
bottles used in a hospital environment may encourage the
contraction of nosocomial diseases.
[0006] The problem which is therefore posed is that of being able
to improve the external appearance, cleanliness and image of gas
bottles, particularly when the bottle contains medical gas,
laboratory gas used for analysis purposes, high-purity industrial
gas for the electronics industry or gas that can be used for the
manufacture of foodstuffs.
[0007] Certain solutions to this problem have already been proposed
but none is entirely satisfactory.
[0008] For example, it is known practice to use a protective net
made of plastic which is slipped directly over the cylindrical
barrel of the bottle so as to protect it locally from impact.
However, it has been found, in practice, that the net tends to
deform if not changed regularly and therefore no longer performs
its protective function. In addition, the net does not protect
certain parts of the bottle, such as the protective cowling with
which the bottle is equipped.
[0009] Furthermore, it has also been proposed for a thermoformed
film to be arranged around the cylindrical barrel of the bottle.
Although such a thermoformed film affords the bottle good
protection, it does not give a sufficient guarantee in terms of
hygiene, particularly since, on the one hand, this type of film is
generally interrupted under the protective cowling and, on the
other hand, below the barrel of the bottle, that is to say under
its base, which leaves the bottom of the bottle and the means of
controlling the outlet of gas therefrom unprotected. Furthermore,
its placement, performed by hand, is industrially restrictive
because it represents a lengthy operation.
[0010] Also known is for the bottle to be placed in a rigid
cardboard casing which affords said bottle protection essentially
during transport because, once the bottle has been delivered to the
site at which it is to be used, the cardboard packaging is removed
and discarded because it is often damaged or dirty. In other words,
once the bottle has reached its place of use, it becomes devoid of
any protection and, upon return having been emptied, it will once
again suffer damage during transport.
[0011] Furthermore, it has also been proposed for the bottle at its
place of use, particularly in at-risk areas such as operating
theater complexes as far as bottles for medical use are concerned,
to be placed in a fabric bag or a rigid metal container enveloping
the barrel of the bottle. However, here again, the solution is not
ideal because certain parts of the bottle are unprotected or are
protected not very efficiently, particularly the protective cowling
and the members it contains, such as a valve unit or a pressure
reducing valve assembly.
[0012] Such solutions have been described in particular in the
following documents UA-A-5,422,152, FR-A-2703434, FR-A-1512098,
U.S. Pat. No. 3,787,993, EP-A-581665 or WO-A-98/16776.
[0013] Reference may also be made to documents U.S. Pat. No.
5,253,760, U.S. Pat. No. 3,921,872, U.S. Pat. No. 4,967,923,
JP-A-07269790 and FR-A-2706140 which describe various technical
solutions that can be applied to the transporting and/or protecting
of compressed-gas bottles.
[0014] From there, the object of the invention is to solve the
above problem by providing a solution which is more effective in
terms of protection and the guaranteeing of hygiene than those
taught in the prior art, so as to guarantee the gas bottles a high
level of external cleanliness and hygiene.
[0015] The solution of the invention consists in a gas bottle
comprising a bottle body of cylindrical overall shape comprising
means of controlling the outlet of the gas and a protective cowling
arranged around the means of controlling the outlet of the gas,
characterized in that:
[0016] the bottle body is at least partially covered by at least a
first protective casing, and
[0017] the protective cowling is at least partially covered by at
least a second protective casing.
[0018] In another aspect, the invention relates also to a gas
bottle comprising a bottle body of cylindrical overall shape
comprising means of controlling the outlet of gas, characterized in
that:
[0019] the bottle body is at least partially covered by at least a
first protective casing, and
[0020] the means of controlling the outlet of gas are at least
partially covered by at least a second protective casing.
[0021] In the context of the invention:
[0022] "means of controlling the outlet of gas" is the name given
to the members which control the outlet of the gas contained in the
bottle, such as on/off valves, gas valves, gas pressure reducers,
combined gas pressure reducing valve assemblies and combined
pressure reducing valve-flow meter assemblies.
[0023] "protective cowling" is the name given to any
three-dimensional structure, generally rigid, able to provide the
members or means of controlling the outlet of gas with mechanical
protection against impacts of any kind; for example the cowling may
have a simple "bell-housing" shape or a more complex shape such as
the one described in document EP-A-747796.
[0024] As the case may be, the gas bottle of the invention may have
one or more of the following features:
[0025] the bottle body is covered over at least 70% of its external
surface area by at least the first protective casing and/or in that
the protective cowling and/or the means of controlling the outlet
of gas are covered over at least 70% of their external surface area
by at least the second protective casing, and are preferably
covered over between 80 and 98% of the surface area.
[0026] said first protective casing and second protective casing
are a single protective casing and/or form a one-piece covering
structure.
[0027] said first protective casing and second protective casing
are separate and/or not attached to one another.
[0028] the second protective casing covering the means of
controlling the outlet of gas comprises at least one cutout or
precut allowing an operator to have access, through said cutout or
precut to said means of controlling the outlet of gas under said
second protective casing.
[0029] the second protective casing covering the protective cowling
comprises at least one cutout or precut that coincides with and/or
is placed opposite at least one opening in the protective cowling
to allow an operator to have access, through said cutout or precut
and said opening, to the means of controlling the outlet of gas
which means are situated inside the protective cowling.
[0030] the first protective casing and/or the second protective
casing are made of a sheet or structure of a material chosen from
cardboard, varnished cardboard, plasticized cardboard, or a
polymer.
[0031] the protective cowling and/or the means of controlling the
outlet of gases are at least partially and temporarily covered by
at least a third protective casing and/or a fourth protective
casing; the third protective casing and/or the fourth protective
casing are preferably made of a sheet or structure of a material
chosen from polymers, preferably PET (polyethylene) or PVC
(polyvinyl chloride), preferably PET.
[0032] the first protective casing and/or the second protective
casing are themselves covered with a third external casing for
temporary protection used while the bottle is being transported;
said third casing preferably comprises one or more handles allowing
an operator to carry a gas bottle using at least one handle.
[0033] the first protective casing has a disk-shaped bottom; said
bottom is preferably rigid and/or made of polymer.
[0034] the first protective-casing forms a sleeve able to encompass
at least 80% of the body of the bottle.
[0035] Furthermore, the invention also relates to protective
packaging for a gas bottle, as such, formed of a first protective
casing portion of rectangular shape to cover at least part of the
cylindrical body of a gas bottle and of a second protective casing
portion to cover at least part of the control members of said
bottle and/or of a protective cowling protecting said control
members, the first protective casing portion and said second
protective casing portion being secured together and/or formed as a
single piece, and the first casing portion further comprising a
disk-shaped bottom fixed securely to said first casing portion so
as to protect at least part of the bottom of the gas bottle.
[0036] As the case may be, the packaging of the invention may have
one or more of the following features:
[0037] the first protective casing portion and said second
protective casing portion are secured to one another and formed of
a single piece of cardboard sheet, preferably a sheet of cardboard
covered with a varnish or a polymer film.
[0038] at least the second protective casing portion has one or
more cutouts or precuts.
[0039] the first protective casing portion has two longitudinal
edges, at least one of said edges bearing at least one adhesive
strip; said adhesive strip borne by one of said edges is preferably
able to collaborate with the other of said edges; as a preference,
the edge bearing said adhesive strip adheres by bonding to the
other edge.
[0040] The solution of the invention, namely the fact of protecting
not only the body of the gas bottle but also its upper part
(cowling and/or means of controlling the outlet of gas) has the
following advantages:
[0041] it is simple and quick for the manufacturer to fit once the
bottle has been conditioned,
[0042] it allows the bottle, including the operating members,
namely the valve, the pressure reducer and the various gas outlets,
particularly in the case of a bottle with a built-in pressure
reducing valve, to maintain a level of external cleanliness and
hygiene over time,
[0043] it allows the affixing of special-purpose logos to qualify
the gases, provide an identification code, give legal notices or
any other useful information or wordings and labels that can be
used to trace the bottle through the various successive users,
without a risk of adversely affecting the surface of the bottle
using inopportune and repeated markings,
[0044] it allows a quick inspection of the external appearance or
the state of use of the bottle,
[0045] it allows the presence of a sealing device constituting a
user guarantee system, and
[0046] it leads to a reduction in the time spent on repainting
operations and on bottle maintenance downtime.
[0047] The invention will now be better understood by virtue of a
detailed description of some embodiments which are illustrated in
the appended figures.
[0048] The present invention relies on the fitting, around the
cylindrical body 1 of the bottle and the protective cowling 2, of
protective casings 11, 21, 30, each of which consist of one or more
thicknesses which may or may not be preassembled.
[0049] One 21 of these casings, preferably rigid, protects the
protective cowling 2 and the means 3 of controlling the outlet of
gas, that is to say the operating members 3 of the bottle (valve,
pressure reducer, outlets, etc.). This rigid part 21 may also
protect part of the body 1 of the bottle, that is to say may extend
along the body 1 of the bottle.
[0050] The bottles to which the invention relates are of varying
sizes (typically with a capacity of up to about 50 liters of water)
but preferably of small size, because small bottles (with a
capacity of about 5 liters of water) are more likely to be carried
around and handled by various operators and therefore to be
subjected to various somewhat contaminating environments.
[0051] In the case of gas bottles for medical use, such a
protective system falls within the context of pharmaceutical
qualification of the product contained in the bottle.
[0052] Using one or more protective casings 11, 21, 30, 40
according to the present invention affords a solution to the
following problems:
[0053] external attacks (scratching, flaky paint, etc.),
[0054] level of external cleanliness unsatisfactory and variable
over time,
[0055] level of hygiene unsatisfactory and variable over time,
[0056] absence of pharmaceutical qualification of the product,
[0057] absence of special logos on the bottles to qualify the image
of the gases according to the expectations of their respective
markets,
[0058] absence of functionality such as stability of the bottle,
protection of the operating members (valve, pressure reducer,
outlets), obvious visual indication of the state of use of the
bottle,
[0059] absence of protection of the paintwork of the body of the
bottle, leading to maintenance costs,
[0060] absence of objective criteria against which to check the
external appearance of the bottles during conditioning.
[0061] More specifically, according to the invention, the bottle is
protected by a first protective casing 11 arranged around the body
1 of the bottle, a second protective casing 21 arranged around the
protective cowling 2 and possibly a third casing 30 encompassing
said first casing 11 and second casing 21, for example while the
bottle is being transported or handled.
[0062] The first protective casing 11 constitutes an external
thickness covering the body 1 of the bottle of a length equal to or
approximately equal to the total height of the bottle that is to be
protected and of a diameter slightly greater than the diameter of
the bottle and the constituent material of which is either a
polymer, preferably PET (polyethylene) and transparent, or a rigid
cardboard casing, possibly varnished or plasticized, as detailed
below.
[0063] Furthermore, as shown in FIGS. 13 to 16, this first
protective casing 11 surrounding the body 1 of the bottle
preferably comprises a rigid and flat bottom 12 which, on the one
hand, makes said first casing 11 easier to fit around the bottle
and, on the other hand, stabilizes the bottle when it is placed in
a vertical position. In addition, the presence of a bottom 12
secured to the first casing 11 makes it possible to enhance the
hygiene of the bottle by preventing dust or other dirt from
infiltrating between the body 1 of the bottle and said protective
casing.
[0064] As detailed in FIG. 13, the protective packaging 11, 21,
viewed here from its inside, that is to say from the side in
contact with the body 1 of the bottle, is formed of a first
protective casing portion 11 of rectangular overall shape to cover
the cylindrical body of a gas bottle and of a second protective
casing portion 21 to cover at least part of the protective cowling
2 protecting the control members 3. The first protective casing
portion 11 and the second protective casing portion 21 are secured
to one another and formed as a single piece of cardboard sheet
covered externally with a varnish or with a polymer film. The first
casing portion 11 carries the disk-shaped bottom 12 fixed securely
to said first casing portion 11 via a plastic strip 21, itself
fixed, for example by bonding, to the sheet that forms the first
casing portion 11. When the packaging is fitted around the bottle,
the two ends of the strip 21 may be joined together by clipping.
Furthermore, an adhesive strip 22 is provided on one of the
longitudinal edges of the first casing portion 11 to allow it to be
arranged and fixed in position around the body 1 of the bottle, the
edge 29 with the adhesive strip 22 covering the edge 28 without
adhesive strip and bonding thereto, via said adhesive strip 22.
[0065] However, in some cases, the presence of a flat bottom 12 is
not necessary and it is possible either to add nothing further or
to add just one or more annular rings 12' which hug the base of the
first casing 11, near the bottom of the bottle.
[0066] The second protective casing 21 constitutes a thickness
guaranteeing the members or means 3 of controlling the outlet of
gases contained in the bottle, for example a valve or a gas
pressure-reducing valve assembly, a high level of hygiene. When
said members or means of controlling the outlet of gases are
protected by a protective cowling 2, then this second protective
casing 21 covers all or part of the external surface of said
protective cowling 2, or may also even cover part of the body of
the bottle. The second protective casing 21 may have a cardboard
rigid part, for example made of plasticized or varnished cardboard.
Notches or precuts 23, 24, blanked off before entry into service,
are provided on this rigid second protective casing 21 to allow the
operator to access the operating members 3 of the bottle (valve,
pressure reducer, outlets). This disposable or non-disposable
thickness 21 may bear special-purpose graphics 25, the quality of
which is renewed on each conditioning operation.
[0067] Furthermore, a third thickness 30, the constituent material
of which may be a polymer, preferably PET, varnished cardboard or
plasticized cardboard, protects the bottle partially or in full
while it is being transported from the conditioning and packaging
center to its place of use (hospital, care center or mobile
emergency medical service, for example) or alternatively to a
storage site prior to use. The other protective casings 11 and 21
may nonetheless be used without this last thickness 30. This third
disposable or non-disposable thickness 30 may also bear specific
graphics the quality of which is renewed on each conditioning
operation. As this thickness 30 is supposed to afford the bottle
full protection during transport and storage, it has therefore to
be sufficiently strong. It could, if need be, be used alone if the
level of hygiene expected by the user is not high. This thickness
is provided with a lateral handle which allows the bottle to be
carried horizontally with ease.
[0068] Finally, a fourth thickness 40, added to the bottle after
the gas which is contained in said bottle has been used, makes it
possible very visibly to embody the state of use of the bottle
(empty/return to the manufacturer) from information that is visible
from afar, thus avoiding any unintentional handling of a bottle
which has already been used. As a preference, such a fourth
thickness 40 covers at least part of the second protective casing
21 when the bottle is empty, as far as the site at which this
bottle is refilled. Advantageously, this fourth thickness 40 is of
a vivid color (for example orange or red) or has special markings
which indicate the condition of the bottle clearly to the user at a
simple glance.
[0069] In general, the number of protective thicknesses is directly
linked to the desired level of hygiene and to the life cycle of the
bottle between two successive conditioning operations.
[0070] The protective casings make it possible to maintain the
level of external cleanliness and hygiene of the bottle over time.
They are therefore associated with an overall usage protocol which
involves several phases, namely:
[0071] at the premises of the manufacturer of gas for medical use:
at the end of the filling of the bottle and of the related checks,
the protective casings, preferably disposable, are fitted to the
bottle.
[0072] during transport: the devices for storing the bottles on the
trucks will be adapted if necessary so as not to damage the
protective casings during transport.
[0073] at the premises of the user: the bottle is delivered as is
to the user who retains all of the protective casings throughout
the storage time. At the time of use of the product, the user
removes the third thickness 30. The bottle then reveals the first
and second casings 11 and 21. The conditioned product offered with
guarantees of cleanliness is thus protected throughout its use.
Once the bottle has been emptied, the user arranges a fourth
thickness 40, preferably colored (orange or red) to indicate the
state of use of the bottle. The bottle is thus protected while it
is being returned to the conditioning center.
[0074] at the premises of the manufacturer of gas for medical use:
the user places the bottle at the disposal of the manufacturer for
return to the conditioning center. The colored fourth protective
casing 40 is removed prior to conditioning when the bottles are
being sorted.
[0075] During the reconditioning of the bottles, the bottle casings
are preferably systematically exchanged for new clean casings.
[0076] As a preference, in the case of small bottles, means
allowing the bottle to be carried with a lateral handle 35, 36 (or
several of these) situated on the outermost protective casing 30
are provided and this allows quick and easy removal after each
operation of conditioning at the premises of the manufacturer.
[0077] As an option, in order to improve the level of hygiene, it
is possible, when conditioning the gas, either for the packaging to
be impregnated with a disinfectant product or for the packaging and
the bottle (body and control members) to be treated with a
disinfecting and/or cleaning solution.
[0078] The invention is particularly well suited to use within a
hospital or care establishment, or an on-site intervention unit,
particularly a mobile unit of the emergency medical services
type.
