Patent Application
20180022515
The present invention relates to devices, such as containers, defining variable-volume storage chambers and methods of making such devices, and more particularly, to such devices with co-extruded outer bodies and inner bladders and to related methods.
One of the drawbacks of current devices for storing products, such as food or medicinal products, is that the multiple parts of the devices must be manufactured separately, such as by molding, and then assembled together. This can be particularly time consuming and expensive when the devices are used for storing sterile food products, medicinal products, or other products requiring that the products be sterile filled and/or maintained sealed with respect to ambient atmosphere during storage and/or use of the device. For example, in devices including flexible bladders defining variable-volume storage chambers and relatively rigid outer bodies or housings, the bladders are formed separately from the outer bodies, and the bladders are filled, or otherwise assembled to the outer bodies and then filled. These multiple assembly steps can be time consuming and expensive and can subject the various parts to contamination.
Accordingly, it is an object of the present invention to overcome one or more of the above-described drawbacks and/or disadvantages of the prior art.
In accordance with a first aspect, the present invention is directed to a device comprising a first portion including a first polymer, and a second portion that is relatively flexible in comparison to the first portion and includes a second polymer that is substantially not bondable to the first polymer. A chamber of the device is hermetically sealable with respect to ambient atmosphere and is defined by (i) an interior of the second portion, and/or (ii) a space formed between the first and second portions. A third portion of the device includes a third polymer that is bondable to the first and second polymers and fixedly secures the first and second portions to each other.
In some embodiments of the present invention, the first polymer includes first and second monomers, the second polymer includes third and fourth monomers that are different than the first and second monomers and substantially not bondable thereto, and the third polymer includes fifth and sixth monomers. The fifth monomer is at least substantially similar and bondable to the first and/or second monomers for bonding the third polymer to the first polymer, and the sixth monomer is at least substantially similar and bondable to the third and/or fourth monomers for bonding the third polymer to the second polymer. In some such embodiments, the fifth monomer is the same as or substantially the same as the first and/or second monomers, and the sixth monomer is the same as or substantially the same as the third and/or fourth monomers.
In some embodiments of the present invention, the first, second and third portions are co-extruded. In some such embodiments, the first, second and third portions are co-extrusion blow-molded. In some embodiments of the present invention, the first portion defines a relatively rigid outer body, the second portion defines a relatively flexible inner bladder, and the third portion fixedly secures the outer body and/or the inner bladder to the other.
In some embodiments of the present invention, the chamber is a variable-volume storage chamber, and the device further comprises a one-way valve fixedly secured to the first, second and/or third portions of the device and in fluid communication with the chamber. The one-way valve defines a normally closed position that hermetically seals the chamber with respect to the ambient atmosphere, and an open position that allows substance to flow out of the chamber and device through the one-way valve. In some such embodiments, the one-way valve substantially prevents the ingress of bacteria and other contaminants into the chamber in both the closed and open positions.
In some embodiments of the present invention, the one-way valve includes a flexible valve member that is movable from the closed to the open position in response to substance at an inlet to the one-way valve exceeding a valve opening pressure. In some such embodiments, the flexible valve member defines a normally closed axially-extending valve opening. Preferably, the one-way valve further includes a relatively rigid valve seat that engages the flexible valve member in the normally closed position and defines the normally closed axially-extending valve opening therebetween.
In some embodiments of the present invention, the one-way valve includes a valve member formed of an elastic material and including an axially-extending valve portion forming a normally closed, axially-extending valve opening. The valve portion is movable radially between a normally closed position, and an open position with at least a segment of the valve portion spaced radially away from the closed position to connect the valve opening in fluid communication with the variable-volume chamber, and thereby allow the passage of fluid from the variable-volume chamber through the valve opening.
In some embodiments of the present invention, the device further comprises a pump coupled between the variable-volume chamber and the one-way valve for pumping substance from the chamber through the one-way valve. In some such embodiments, the pump is configured to pump discrete portions of substance from the chamber through the one-way valve. During pumping, the one-way valve and chamber maintain any remaining substance in the chamber in an aseptic condition and sealed with respect to ambient atmosphere.
In some embodiments of the present invention, the pump includes a compression chamber, a compressive surface receivable within the compression chamber, and a manually-engageable actuator coupled to the compression chamber and/or compressive surface. The compressive surface and/or compression chamber is movable relative to the other by the manually-engageable actuator between (i) a rest position, and (ii) at least one actuated position for pressurizing fluid within the compression chamber and, in turn, dispensing fluid through the one-way valve. In some such embodiments, the compressive surface and/or compression chamber is movable relative to the other by the manually-engageable actuator between (i) a first position with the compression chamber coupled in fluid communication with the variable-volume chamber for receiving fluid from the variable-volume chamber into the compression chamber, and (ii) a second position with the compressive surface received within the compression chamber, and the compression chamber substantially sealed with respect to the variable-volume chamber to pressurize fluid within the compression chamber and, in turn, dispense pressurized fluid through the one-way valve. In some such embodiments, a flexible member defines on one side thereof the manually-engageable actuator, and defines on another side thereof the compressive surface. In some such embodiments, the flexible member is substantially dome shaped, and the compression chamber is defined by a recess opposing the substantially dome-shaped flexible member.
In some embodiments of the present invention, the pump is co-molded with the one-way valve. In some such embodiments, the pump and one-way valve form a pump and valve assembly including a base defining a valve seat, a relatively flexible manually-engageable actuator for pumping substance through the one-way valve, and a relatively flexible valve member engaging the valve seat and forming a normally closed valve opening therebetween. In some such embodiments, the pump and valve assembly further comprises (i) a penetrable and laser resealable portion, and/or (ii) a one-way filling valve for filling the variable-volume chamber.
In some embodiments of the present invention, the penetrable and laser resealable portion and/or the one-way filling valve is co-molded with the pump and valve assembly. In some such embodiments, the pump and valve assembly includes a support surface formed integral with the base and movable relative thereto. The manually-engageable actuator and valve member are co-molded to the support surface. The support surface is movable into engagement with the base to fixedly secure the support surface to the base and form a fluid-tight seal, and to place the valve member in engagement with the valve seat forming the normally closed valve opening. Preferably, a flexible gasket is formed on the base and engageable between the base and the body to form a fluid-tight seal. In some such embodiments, the gasket is co-molded with the manually-engageable actuator and valve member. In some embodiments of the present invention, the pump and valve assembly further includes an integral or living hinge extending between the support and base for allowing movement of at least one relative to the other.
In some embodiments of the present invention, at least a portion of the pump, the one-way valve, and/or a surface defining the variable-volume chamber is penetrable by an injection member for filling the variable-volume chamber through the injection member with a fluid to be stored therein, and the resulting penetration aperture is thermally resealable such as by applying laser energy thereto.
In accordance with another aspect, the present invention is directed to a device comprising first means for forming an outer surface of the device and including a first polymer. Second means of the device includes a second polymer that is substantially not bondable to the first polymer for forming a relatively flexible inner surface of the device in comparison to the first means, and a chamber that is hermetically sealable with respect to ambient atmosphere and defined by (i) an interior of the second means, and/or (ii) a space formed between the first and second means. Third means of the device includes a third polymer that is bondable to the first and second polymers for fixedly securing the first and second means to each other. In some embodiments of the present invention, the first means is a relatively rigid outer body, the second means is a relatively flexible inner bladder, and the third means is a portion of the device that is bonded to and fixedly secures the body and/or bladder to the other. Preferably, the body, bladder and portion bonded thereto are co-extrusion blow molded.
In accordance with another aspect, the present invention is directed to a method comprising the following steps:
(i) extruding a first portion of a device including a first polymer;
(ii) co-extruding with the first portion a second portion of the device that is relatively flexible in comparison to the first portion, and that includes a second polymer that is substantially not bondable to the first polymer;
(iii) co-extruding a third portion of the device including a third polymer that is bondable to the first and second polymers; and
(iv) bonding the third portion to the first and second portions to fixedly secure the first and second portions to the third portion, and forming a chamber that is hermetically sealable with respect to ambient atmosphere defined by (i) an interior of the second portion, and/or (ii) a space formed between the first and second portions.
Some embodiments of the present invention further comprise co-extrusion blow molding the first, second and third portions. Some such embodiments further comprise substantially simultaneously co-extruding the first and second polymers, sequentially co-extruding the third polymer and, in turn, bonding the third polymer to the first and second polymers to fixedly secure the first, second and third portions to each other. Some such embodiments further comprise extruding a first parison of the first polymer, co-extruding a second parison of the second polymer within the first parison, sequentially co-extruding a third parison of the third polymer, and bonding the third polymer to each of the first and second polymers.
Some embodiments of the present invention further comprise co-molding a pump and one-way dispensing valve assembly, and fixedly securing the pump and one-way dispensing valve assembly to the first, second and/or third portions. The one-way dispensing valve is in fluid communication with the variable-volume chamber, and the variable-volume chamber is hermetically sealed with respect to ambient atmosphere.
In some embodiments of the present invention, the co-molding step includes co-molding as part of the pump and valve assembly (i) a penetrable and thermally resealable portion, and/or (ii) a one-way filling valve. In some such embodiments, the co-molding step includes co-molding as part of the pump and valve assembly a penetrable and thermally resealable portion. In these embodiments, the aseptic filling step includes penetrating the penetrable and thermally resealable portion with an injection member placed in fluid communication with the variable-volume chamber, filling the variable-volume chamber through the injection member, withdrawing the injection member, and thermally resealing, such as by applying laser energy to, a resulting penetration aperture formed in the penetrable and thermally resealable portion.
In some embodiments of the present invention, the co-molding step includes co-molding as part of the pump and valve assembly a one-way filling valve in fluid communication with the variable-volume chamber. In these embodiments, the aseptic filling step includes placing a filling member in fluid communication with an inlet of the one-way filling valve; filling the sterile fluid through the filling member and one-way filling valve and into the variable-volume chamber; removing the filling member from the one-way filling valve; and sealing the variable-volume chamber with respect to ambient atmosphere with the one-way filling valve.
Some embodiments of the present invention further comprise forming a sealed, empty, sterile variable-volume chamber. In some such embodiments, the step of forming a sterile variable-volume chamber includes subjecting the sealed, empty, variable-volume chamber to radiation. In some such embodiments, the radiation is gamma radiation. Some embodiments of the present invention comprise the steps of co-molding the pump and valve assembly or other device closure; co-extruding the first, second and third portions of the device, such as the relatively rigid outer body, flexible inner bladder, and neck; upon molding the two parts, promptly assembling the closure to the neck in an aseptic environment, such as under an overpressure of sterile air, and thereby forming a sealed, empty, sterile variable-volume chamber. Some embodiments of the present invention further comprise aseptically filling the sealed, empty, variable-volume chamber with a sterile fluid.
One advantage of the device and method of the present invention is that the first portion, such as the outer body of the container or other device, and the second portion, such as the inner bladder of the container or other device, can be molded at the same time as one part. Yet another advantage of some currently preferred embodiments of the present invention is that the pump and valve assembly, and/or the pump, penetrable and thermally resealable stopper or filling valve, and dispensing valve assembly, can be co-molded in one part, and attached to the outer body and flexible inner bladder, thus forming such device in approximately two parts.
Other advantages of the present invention and/or of the preferred embodiments thereof will become more readily apparent in view of the following detailed description of the currently preferred embodiments and accompanying drawings.
In
In the illustrated embodiments, the first polymer forming the outer body 12 includes first and second monomers, the second polymer forming the flexible inner bladder 14 includes third and fourth monomers that are different than the first and second monomers and substantially not bondable thereto, and the third polymer forming the neck 18 includes fifth and sixth monomers. The fifth monomer is at least substantially similar and bondable to the first and/or second monomers for bonding the third polymer/neck 18 to the first polymer/outer body 12, and the sixth monomer is at least substantially similar and bondable to the third and/or fourth monomers for bonding the third polymer/neck 18 to the second polymer/flexible inner bladder 14. In the illustrated embodiment, the fifth monomer is the same as or substantially the same as the first and/or second monomers, and the sixth monomer is the same as or substantially the same as the third and/or fourth monomers. As may be recognized by those of ordinary skill in the pertinent art based on the teachings herein, the first, second and third polymers, and the monomers forming each of the polymers, may take the form of any of numerous different polymers and/or monomers that are currently known, or that later become known, for performing the functions of the polymers and monomers as described herein. Further, the devices may take any of numerous different configurations, and the components of the devices may take any of numerous different physical and/or chemical characteristics, that are currently known, or that later become known. In the exemplary illustrated embodiment, the outer body 12 may be relatively rigid in comparison to the flexible inner bladder 14, but nevertheless may be manually squeezable to pressurize the inner bladder 14 and, in turn, pressure the fluid or other substance within the variable-volume chamber to dispense fluid or other substance therefrom.
As shown in
Also in the illustrated embodiments, the chamber 16 is a variable-volume storage chamber, and as shown in
As shown in
The device 10 further comprises a pump 40 coupled between the variable-volume chamber 16 and the one-way valve 28 for pumping substance from the chamber 16 through the one-way valve 28. The pump 40 is configured to pump discrete portions of substance from the chamber 16 through the one-way valve 28. During pumping, the one-way valve 28 and chamber 16 maintain any remaining substance in the chamber in an aseptic condition and sealed with respect to ambient atmosphere.
As shown in
Also in the illustrated embodiments, the pump 40 is co-molded with the one-way valve 28. As shown in
The pump and valve assembly 48 further comprises a penetrable and thermally resealable portion 58 that is co-molded to the support 54 and overlies an aperture 60 in the base 50 when attached thereto. The penetrable and thermally resealable portion 58 allows filling therethrough of the variable-volume chamber 16 with a needle or like injection member, and thermal resealing of the resulting penetration aperture, such as by applying laser radiation thereto.
As show in
The currently preferred embodiment of the device 10 is manufactured in accordance with the following steps:
(i) extruding the first portion or body 12 that includes the first polymer;
(ii) co-extruding with the first portion or body 12 the second portion or flexible inner bladder 14 that includes the second polymer that is substantially not bondable to the first polymer;
(iii) co-extruding the third portion or neck 18 that includes the third polymer that is bondable to the first and second polymers; and
(iv) bonding the third portion or neck 18 to the first and second portions or body and flexible inner bladder 12 and 14, respectively, to fixedly secure the body and inner bladder to the neck.
In the illustrated embodiment, the body 12, bladder 14 and neck 18 are co-extrusion blow molded. Preferably, the method of manufacture involves substantially simultaneously co-extruding the first and second polymers, sequentially co-extruding the third polymer and, in turn, bonding the third polymer (or neck 18) to the first and second polymers (or body 12 and inner bladder 14) to fixedly secure the body, bladder and neck to each other. More specifically, the method of manufacture includes extruding a first parison of the first polymer, co-extruding a second parison of the second polymer within the first parison, sequentially co-extruding a third parison of the third polymer, and bonding the third polymer (or neck) to each of the first and second polymers (or body and bladder).
As described above, the pump and one-way dispensing valve assembly 48 is co-molded and fixedly secured to the neck 18 to thereby form the variable-volume chamber 16 that is hermetically sealed with respect to ambient atmosphere. Upon assembly, the one-way dispensing valve 28 is in fluid communication with the variable-volume chamber 16, and the variable-volume chamber 16 is hermetically sealed with respect to ambient atmosphere.
The device defining the sealed, empty, variable-volume chamber is then sterilized such as by applying gamma radiation thereto. Alternatively, as described above, the pump and valve assembly may be assembled to the neck promptly upon molding when both parts are sterile or substantially sterile due to the heat of molding. The sterile parts are preferably automatically assembled promptly upon molding, such as at the time of discharge from the molds or shortly thereafter, such as with a robot or other automated assembly device, under an overpressure of sterile air or other gas to form the device with an empty, sterile, variable-volume chamber.
The sealed, empty device defining the sterile variable-volume chamber then may be aseptically filled. In the illustrated embodiment, the aseptic filling includes penetrating the penetrable and thermally resealable portion 58 with an injection member (not shown) placed in fluid communication with the variable-volume chamber 16, filling the variable-volume chamber through the injection member, withdrawing the injection member, and thermally resealing, such as by applying laser energy to, a resulting penetration aperture formed in the penetrable and thermally resealable portion.
In an alternative embodiment of the invention, rather than include a penetrable and thermally resealable portion, the pump and valve assembly 48 includes a valve-in and vent-out assembly including a one-way filling valve for filling the variable-volume chamber 16 therethrough, and a one-way venting valve for venting gas from the variable volume chamber upon filling the fluid or substance into the variable-volume chamber 16. Preferably, the valve-in and vent-out assembly is co-molded with the pump and valve assembly 48 in the same manner, or substantially the same manner that the penetrable and thermally resealable portion 58 is co-molded with the pump and valve the assembly.
In the alternative embodiments including the valve-in and vent-out assembly, the aseptic filling step includes placing a filling member in fluid communication with an inlet of the one-way filling valve; filling the sterile fluid through the filling member and one-way filling valve and into the variable-volume chamber; removing the filling member from the one-way filling valve; and sealing the variable-volume chamber with respect to ambient atmosphere with the one-way filling valve.
The one-way valve and pump may take the form of any of numerous different valves and/or pumps that are currently known, or that later become known, including any of the one-way valves and/or pumps that are disclosed in the following patents and patent applications that are hereby expressly incorporated by reference in their entireties as part of the present disclosure: U.S. patent application Ser.

For example, any of numerous different materials, including any of numerous different polymers, may be employed that are currently known, or that later become known. Similarly, the device may take the form of any of numerous different devices, including any of numerous different containers, or containers or other devices with or without valves, penetrable and thermally resealable portions, and/or pumps, that are currently known, or that later become known. Further, the devices and methods of the present invention may be used to store and dispense any of numerous different products or substances, including without limitation, food products, such as low acid food products, dairy, milk-based, soy-based, water-based, juice-based or other food products, and pharmaceutical, ophthalmic, dermatological, and vaccine products, and industrial products, such as paints, adhesives, and components of the foregoing products. Although the device and method of the present invention are particularly suited for storing and dispensing sterile products that should be maintained sterile and hermetically sealed with respect to ambient atmosphere during storage and throughout the period of dispensing product from the device, they equally may be used with other products that are not sterile, or that do not require that the product be hermetically sealed with respect to ambient atmosphere. Accordingly, this detailed description of the currently preferred embodiments is to be taken in an illustrative as opposed to a limiting sense.
