Abstract

A package containing a meltable solid composition which is curable by moisture, is intended both for storage and dispensing of the composition. The package comprises a tubular body portion (10), an end member (12) permanently closing one end and a follower member (18) which is a sliding fit in the body portion. The follower member is of heat conductive material and is intended to be heated and pressed against the composition when melted composition is to be dispensed through an outlet (24) in the member by means of a piston apparatus 32. Prior to dispensing the package may have sealing tape means covering the outlet and the join between the follower member (18) and tubular portion 10, and a closure member (14) to minimise ingress of moisture to the packaged composition. The follower member restricts spurious emission of melt or ingress of moisture during dispensing and it has peripheral rim (22) projecting towards the end member (12). The temperature of disc (34) of the piston apparatus is controlled so that preferably only composition contained within rim (22) becomes molten during dispensing. To form the package molten composition is put into the container, the follower member is then slid down onto the upper surface of the composition, the hole (24) is sealed, a wooden plug is introduced into the open end of the container so as to abut the member (18), the container is then inverted and the composition allowed to set, any entrapped air rising to the end member (12). <IMAGE>

Description

SPECIFICATION Packaging and dispensing meltable, moisture curable compositions Various formulations for moisture curable compositions have been proposed. For example, adhesive compositions based on isocyanate terminated prepolymers have been proposed and their use in various bonding operations has also been proposed. UK patent specification No. 1 540634 discloses inter alia the use of compositions based on certain prepolymers for bonding soles to shoes, including certain prepolymers derived from diphenyl methane diisocyanate and polyesters derived from an aliphatic dicarboxylic acid and an aliphatic diol, which are intended to be melted and supplied to the work in molten form.An adhesive composition of this kind is available from Bostik Limited under the names PA 5102 and Bostik Supergrip 9801 and is capable of use for attaching soles to shoes and various other bonding processes.
It will be apparent that moisture curable compositions are cured by reaction with moisture and it is therefore highly desirable to restrict and preferably avoid exposure of these compositions to moisture prior to use, so as to ensure a required uniformity of performance of the composition when used. It is therefore desirable to package and store the composition in a moisture proof package. It is equally important to provide for emptying of the package at the time of use without premature cure of the composition and with minimum inconvenience to the operator even when the operator requires only a portion of the composition to be withdrawn from the package at any one time as may occur during intermittent use of the composition over a period of hours or even several days.We have found that these requirements cannot be met consistently by means of packages and equipment available for handling larger quantities of adhesive.
Among available equipment are various apparatuses intended to pump melted adhesive from a drum-like container via a hose connected with a piston of the apparatus which piston is adapted to be pressed into the drum to expel the melted adhesive. This type of apparatus is generally suitable for use with many types of adhesive; we have found that when used with moisture curable adhesive, problems tend to result from seepage of the melted composition past the piston in the drum. This material hardens and adheres ten- aciously to the drum and the piston and leads to not only wastage of adhesive, but also difficulties in consistently preventing access of moisture of the atmosphere to adhesive in the drum.This may lead to unpredictable performance of the apparatus and or adhesive during prolonged intermittent use of the apparatus to discharge adhesive from a single -drum, and difficulties or inconvenience in removing the piston from the discharged drum when a fresh drum of adhesive comes to be used.
Among various objects of the present invention are to provide an improved package for a meltable, moisture curable composition.
The invention provides in one of its aspects a package comprising a moisture proof container comprising a tubular body portion and an end member closing one end of the tubular body portion the other end being open, a solid composition which may be melted in the container contained in the container, a follower member of heat conductive moisture proof material adjacent the surface of the solid composition closest to the open end of the tubular body portion the follower member being a sliding fit in the tubular body portion and having an outlet therein, first sealing means sealing the outlet against ingress of moisture and second sealing means sealing the gap between the outer periphery of the follower member and the tubular body portion against ingress of moisture.
Any suitable sealing means may be used for first and second sealing means. Preferred as the first and second sealing means is moisture impermeable tape, e.g. aluminium coated polyester film self adhesive tape. A piece of this tape is stuck over the outlet (for example over a hole in the preferred follower member) and, another piece folded into an "L" shape, is stuck to the follower member and to the inner wall of the tubular body portion to seal the gap between the follower member and the tubular body portion. Other sealing means may of course be used, for example for sealing the gap between the follower member and the tubular body portion a bead of a sufficiently moisture impermeable hot melt adhesive composition may be applied using a hot melt glue gun, for example as available from the Applicant company.
The invention provides in another of its aspects a package comprising a moisture proof container comprising a tubular body portion and an end member permanently secured thereto and closing one end of the.
tubular body portion the other end of the tubular body portion being open and provided with a closure member, a solid composition which may be melted in the container in the container, a follower member of heat conductive, moisture proof material adjacent the surface of the solid composition closest to the open end of the tubular body portion the follower member being a sliding fit in the tubular body portion and having an outlet therein, and having around its periphery a rim projecting towards the end member and being disposed in engagement with an inner wall of the tubular portion for sliding movement into the container.
In a package according to the invention, conveniently the follower member is formed from steel sheet. The outlet of the follower member is preferably a hole through a central region of the follower member. The tubular body portion, end member and follower member are suitably sufficiently strong to withstand pressures generated when emptying the container using apparatus of the type hereinbefore mentioned intended to pump melted adhesive from a drum-like container comprising a piston adapted to be pressed into the drum. A suitable container may be fabricated from sheet steel.
In a preferred package in accordance with the invention a closure member is secured to the tubular body portion at the open end thereof during storage and transit thus to close the container against ingress of foreign matter to the tubular body portion above the follower member, to minimise the possibility of accidental damage to the sealing means and to act as a further barrier to ingress of moisture into the package.
In a preferred package in accordance with the invention, the follower member comprises a rim projecting towards the end member of the container and in sliding engagement with an inner wall of the body portion which rim projects from a flat plate portion of the follower member.
In a preferred package in accordance with the invention, the follower member comprises a flat disc-like portion which is in contact with a surface of the moisture curable composition.
The arrangement of the package is such that the surface of the follower member and the surface of the composition are complementary and thus facilitate transfer of heat to the surface of the composition.
In a further aspect the invention provides a method of packaging a meltable, moisture curable composition comprising procuring a moisture proof container comprising a tubular body portion and an end member closing one end of the tubular body portion the other end being open, with the open end uppermost, filling the container with the composition in molten condition to a level below the uppermost edge portion of the tubular body portion, introducing into the tubular body portion a follower member of moisture proof material having an outlet therein and which is a sliding fit in the tubular body portion until the follower member rests on the upper surface of the molten composition in the container, sealing the outlet against ingress of moisture, while maintaining the follower member substantially in the position to which it is inserted in the tubular body portion inverting the container, and allowing the composition to cool and solidify with the follower member maintained in substantially said position and with the surface of the composition contiguous with the follower member substantially horizontal and perpendicular to the axis of the tubular portion.
In a method in accordance with the invention we prefer to seal the gap between the follower member and tubular body portion against ingress of moisture, while maintaining the follower member substantially in the position to which it is inserted in the tubular body portion prior to inverting the container.
In a method in accordance with the invention a package is suitably produced in accordance with the invention in its package aspects. Thus, in carrying out a method in accordance with the invention, preferred features of the package discussed hereinbefore are included when carrying out the method of packaging; for example, the follower member preferably comprises a fabricated sheet steel member comprising a flat portion and, around the periphery a rim projecting towards the end member of the container, the rim arranged to be in sliding engagement with an inner wall of the tubular body portion.
In carrying out a method in accordance with the invention a preferred method of maintaining the follower member substantially in the position to which it is inserted in the tubular body portion involves insertion of a plug member as a sliding fit into the open end of the tubular body portion, the plug member abutting the follower member and projecting slightly from the open end of the tubular body portion. Thus when the container is inverted, the inverted container is supported by the plug member through the follower member and composition in the container.In carrying out a method in accordance with the invention, if care is taken, it is unlikely that any significant quantity of air will be trapped between the follower member and the composition; however, if any air comes to be trapped it will rise to the end member of the inverted continer and will be trapped there when the contents become solid. As the composition in the container cools there is a tendency for it to shrink: any shrinkage taking place will tend to occur adjacent the end member leaving a small void adjacent the end member should shrinkage have taken place.
In carrying out a preferred method of packaging, the container is turned the correct way up i.e. with the end member at the bottom of the container, after the contents have solidified and a suitable closure member is secured to close the open end of the tubular body portion.
A method by which a package in accordance with the invention may be emptied comprises removing the closure member (if any), removing the sealing means (if any) (for example in the case of tapes peeling the tapes away or, where a bead of hot melt of adhesive is used this may be removed in the course of emptying the container), inserting a piston so shaped as to be a sliding sealing fit into the open end of the tubular body portion, the tubular body portion being positioned in alignment with the path of motion of the piston, moving the piston into engagement with the follower member while ensuring that an escape path for air trapped between the piston and follower member is provided, heating the piston sufficiently to melt composition in the container adjacent the follower member and pumping molten composition from the container through the outlet in the follower member and a corresponding duct in the piston. Preferably in emptying the container a slight pressure is applied to the piston to maintain it in firm contact with the follower member and a separate pump for example a reciprocating pump or gear pump, is provided to remove molten composition, the pressure applied to the piston gradually urging the piston and follower member towards the end member of the container as molten composition is removed.Conveniently the container is constructed in such a manner that the end member is secured to the tubular body portion in such a manner as to leave a narrow annular space between the end member and the tubular body portion so that where the follower member has a rim as hereinbefore mentioned, when the follower member approaches the end member as the container is emptied, the rim is received in the narrow annular space so that the follower member can be urged into contact with the end member whereby to substantially completely empty the container removing substantially all of the composition.
There now follows a detailed description to be read with reference to the accompanying drawing of a package comprising a moisture proof container and a method of packaging a moisture curable composition embodying the invention. It will be understood that this package and this method of packaging have been selected for description to illustrate the invention by way of example.
The accompanying drawing is a view in cross section of the illustrative package with a closure member in position, and showing above the package a piston of a suitable dispensing apparatus.
The illustrative package comprises a moisture proof container suitable for containing 20 litres of composition. It comprises a tubular body portion 10 and an end member 1 2 closing one end of the tubular body portion 10. The tubular body portion and end member are fabricated of sheet steel and the end member is secured, in moisture proof fashion, to the tubular body portion in such a way as to leave a narrow annular space between the end member and the tubular body portion (not shown in the drawings) for a purpose to be described hereinafter. The end of the illustrative package remote from the end member 1 2 is shown closed by a closure member 14 which may readily be removed.Thus the illustrative package comprises a container itself comprising the tubular body portion and the end member closing one end of the tubular body portion, the other end of the container being upon, and the closure member.
Contained in the container is a solid, meltable, moisture curable adhesive composition 1 6.
The illustrative package further comprises a follower member 1 8. The follower member 1 8 is formed of sheet steel and comprises a flat circular disc shaped portion 20 adjacent the surface of the solid composition closest to the open end of the tubular body portion end, the- disc-shaped portion 20 being contiguous with the upper surface of the solid composition. The follower member 1 8 further comprises an integral rim 22 round the periphery of the disc-shaped portion and projecting therefrom towards the end member 1 2. The rim is disposed in engagement with an inner wall of the tubular portion for sliding movement into the container, and depends from the disc shaped portion to a small extent.It appears this extent is merely sufficient to ensure that when a layer of composition is melted preparatory to dispensing it from the package, the rim extends to a sufficient depth to contain the molten layer. The follower member 1 8 is a sliding fit in the tubular body portion 10. An outlet viz. a hole 24, is provided in a central portion of the disc-shaped portion 20 of the follower member 1 8. The hole 24 is sealed against ingress of moisture by first sealing means, viz. a piece of polyester film/aluminum foil laminate coated with pressure sensitive adhesive on one side to provide a tape, a piece 26 being stuck to the disc-shaped portion 20 covering the hole 24.The illustrative package also comprises second sealing means sealing the gap between the outer periphery of the follower member 1 8 and an inner wall of the tubular body portion 10 against ingress of moisture. The second sealing means is also provided by a piece of the tape aforementioned. The tape is applied as a strip 28 folded into an L-shaped configuration viewed in cross section, one limb of the strip being adhered to the disc-shaped portion 20 of the follower member 1 8 and the other limb being adhered to the inner wall of the tubular body portion 10 of the container.The illustrative package also comprises the closure member 14, which is in the form of a lid secured to a rim of the tubular body portion 10 closing the open end of the container to prevent ingress of foreign matter, protect the sealing means and act as a secondary seal against ingress of moisture to the container during storage and transit.
In carrying out the illustrative method of packaging a moisture curable composition hereinbefore referred to, the package to be formed is the illustrative package. In carrying out the illustrative method the container is placed with its end member down, and filled with meltable, moisture curable composition in molten form almost to the top but leaving sufficient space for introduction of the follower member 1 8 and for a piston 32 of a suitable dispensing apparatus to be described in more detail hereafter. The bottom of the container stands on a horizontal surface so that the upper surface of the molten composition is substantially horizontal.The follower member is then introduced into the tubular body portion 10 (in which it is a sliding fit) and rests on the upper surface of the molten composition; air escapes from the space between the follower member 1 8 and the upper surface of the composition 1 6 as the member 1 8 is introduced, through the hole 24 and around the edges of the follower member 1 8.
When the follower member 1 8 is in position the hole 24 is sealed by sticking in position the piece 26 of tape and the gap between the periphery of the follower member 1 8 and the inner wall of the tubular body portion 10 is likewise sealed by applying the strip 28 of tape. The moisture curable composition 1 6 retains its heat well, and is at this time still in a molten condition. Next, in carrying out the illustrative method of packaging, a wooden plug is introduced into the open end of the tubular body portion (in which it is a sliding fit), the plug abutting the flat, disc-shaped portion 20 of the follower member 18 and projecting from the open end of the tubular body portion of the container.The container is then inverted whilst maintaining the follower member 18 substantially in the position to which it has been inserted in the tubular body portion 10, by means of the plug (not shown).
The plug is then rested on a horizontal surface, supporting the container through the member 1 8 and the mass of still molten composition 1 6. The composition 16 is allowed to cool and solidify with the container in this inverted position, the member 1 8 being maintained in substantially the position to which it was inserted, the disc-shaped portion 20 thus being maintained horizontal. The surface of the composition 1 6 contiguous with the disc-shaped portion 20 of the follower member 1 8 is thus substantially horizontal and perpendicular to the axis of the tubular body portion 10.As the container is allowed to cool with the member 1 8 at the bottom, any entrapped air (of which there should be little) will rise until it reaches the end member 1 2. As the moisture curable composition cools it will shrink to some extent but because the follower member 1 8 is positioned at the downward end during cooling any shrinkage taking place will be apparent adjacent the end member. Thus in the illustrative package there may be a small void adjacent the end member 1 2 but there will be no entrapped air or voids adjacent the follower member 18.When the composition 1 6 has cooled the container is again turned over so that the end member 1 2 is at the bottom, the wooden plug is removed from the open end of the tubular body portion 10 and the closure member 14 is placed on the open end of the tubular body portion 10 and fixed in position thus providing the illustrative package.
When it is desired to dispense the contents from the illustrative package a suitable dispensing apparatus is used as hereinbefore described. This operates on the same principle as many commercially available apparatuses for dispensing melts from drums except that care is taken to ensure that seals used are adequate to prevent leakage of air into the container, for example if the apparatus is only used intermittently and moisture curable compound allowed to cool in the system: if moisture were to be allowed to enter the system then the compound could cure and cause blockages difficult to remove. In use of the illustrative package the closure member 14 is removed and immediately before use the piece 24 and strip 28 of tape are removed.
The container is placed in the apparatus beneath and aligned with the piston 32 which comprises an electrically heated metal disc 34 of a size to be received as a sliding fit in the open end of the tubular body portion 10 of the illustrative package. Around the disc are two O-rings 36 which provide a tight seal against the inner wall of the tubular body portion 10 preventing leakage of air or composition (when it is in molten form) past the piston 32. When the piston 32 is received in the open end of the tubular body portion, an outlet port 38 is aligned with the hole 24 in the follower member 18.The illustrative apparatus comprises a pump (not shown) for pumping molten composition through the port 38 and an outlet pipe 40 to be dispensed from the illustrative apparatus and further comprises means, for example pneumatic cylinders (not shown) for urging the piston 32 downwardly into the container. When the piston 32 is introduced into the tubular body portion 10 with the O-rings sealing against the inner wall of the body portion 10, air is trapped between the piston 32 and follower member 1 8. Means for releasing this trapped air is provided in the piston, comprising a screw member 42 having a sealing plunger portion 44 adjacent a bottom face 46 of the piston 32. When the piston 32 is inserted into the tubular body portion 10 the screw member 42 is screwed to an upper position in which the plunger portion 44 is withdrawn from a cooperating sealing bore in the disc 34 of the piston; thus, entrapped air from between the piston 32 and follower member 1 8 can escape through the bore in the disc 34 and an air passage (not shown) in the screw member 42. The piston 32 can thus be moved into the container until the flat, bottom face 46 contacts the flat, disc-shaped portion 20 of the follower member 18, little or no air being entrapped between the piston and follower member.When the piston 32 has seated against the follower member 1 8 the screw member 42 is screwed downwardly so that the plunger portion 44 enters the cooperating bore in the disc 34 and seals against leakage of air into the system or escape of molten material from the system; a bottom surface of the plunger portion 44 of the screw member 42 is arranged to be flush with the bottom face 46 of the piston 32 when the screw member is in its sealing positioned.
As hereinbefore mentioned the disc 34 of the piston 32 is heated; the temperature of the disc 34 is controlled thermostatically.
When the heated disc 34 is in contact with the follower member 1 8 the temperature of the disc 34 is controlled so that the composition 1 6 in contact with the follower member 18 is melted together with a small depth of the composition 1 6 below the follower member 1 8. However, most of the moisture curable composition 1 6 in the container remains solid. Preferably the temperature of the disc 34 is controlled so that only composition 1 6 contained within the rim 22 of the follower member 1 8 becomes molten (apart from possibly a small amount adjacent the downward edge of the rim). Thus little or no molten composition comes into contact with the wall of the tubular body portion during dispening.
When sufficient of the composition 1 6 has become molten, molten composition may be removed from beneath the follower member 18 and through the hole 24 and the outlet port 38, and through the pipe 40 by the pump for dispensing to any desired position, for example to the soles of shoes. A preferred pump is a reciprocating pump but other forms of pump e.g. gear pumps may be used instead. As molten composition is withdrawn from the container beneath the follower member 1 8 the piston 32 is urged downwardly in the container so that the follower member 1 8 is maintained in contact with the upper surface of the composition 1 6 and no voids are formed.The pressure applied by the piston is just sufficient to urge the piston 32 down the container and maintain the follower member 1 8 in contact with the composition as aforesaid. When the container is almost empty the piston 32 may encounter a void adjacent the end member 1 2 and rapid movement of the piston 32 may occur at this juncture.It is possible to ensure that substantially all of the contents of the container are dispensed by arranging that the rim 22 is received in the aforementioned space between the tubular body portion 10 and the flat surface of the end member 1 2. When the container is empty the screw member 42 is again retracted to withdraw the plunger portion 44 from its cooperating bore, and compressed air is connected to the air passage through the screw member; the compressed air blows the container from the piston 32 and a fresh container of moisture curable composition may be presented to the apparatus and the piston 32 introduced in the manner hereinbefore described.
Composition e.g. Bostik PA5102 in the illustrative package has been found to retain its properties for a substantial period of time without any noticeable curing of the composition and it is possible to dispense the moisture curable composition from the package without any problems being encountered through entrapped air or leakage of moisture into the container during dispensing, even when the dispensing apparatus is switched off for a substantial period of time. If desired, a suitable valve may be disposed in the outlet port 38 of the piston 32 to prevent leakage of air into the pipe 40 when the piston 32 is removed from a container, and to prevent leakage of moisture curable composition from the pipe 40 in the same circumstances.
