NZ 740898 B2 A SPOUTED POUCH ADAPTED TO BE FILLED WITH A FLOWABLE PRODUCT AND METHOD OF PRODUCTION THEREOF The present invention relates to the field of filling of spouted pouches or other containers with a flowable product.
In a known approach spouted pouches are manufactured without a cap and supplied to a filling and capping machine where the pouches are filled and where a cap is assembled onto the neck of the spout. Often manually openable screw caps are employed to close the pouch.
For example WO2014171834 discloses to collect spouted pouches in transport rails. It is disclosed that, after the filling, the spouted pouches are sealed by a cap. It is disclosed that it is conceivable that the spouted pouches are provided with caps before they are transported to the filling machine, where the caps are removed prior to the filling process and then replaced after filling. As an alternative it is disclosed that the caps are supplied to the filling machine, independent of the spouted pouches.
The flowable products that are stored in spouted pouches may e.g. be foodstuffs, which may place stringent demands on aseptic handling and sealing of the filled spouted pouches.
The present invention aims to provide a cost effective solution for the production of filled spouted pouches, in particular of aseptically filled spouted pouches.
The discussion of documents, acts, materials, devices, articles and the like is included in this specification solely for the purpose of providing a context for the present invention. It is not suggested or represented that any or all of these matters formed part of the prior art base or were common general knowledge in the field relevant to the present invention as it existed before the priority date of each claim of this application.
Throughout the description and claims of this specification, the word "comprise" and variations of the word, such as "comprising" and "comprises", is not intended to exclude other additives, components, integers or steps.
The present invention provides, in combination, a spouted pouch adapted to be filled with a flowable product by a filling machine, a plug, and a cap, wherein said combination includes the spouted pouch comprising: a flexible material pouch body, a spout having a molded spout body of plastic material, said spout body having at a lower end thereof an attachment portion that is attached to the pouch body, wherein said spout body has at an upper end thereof a tubular neck, which neck has an interior surface delimiting at least a section of a product passage that extends from a lower product passage opening through the spout body to a mouth opening at a top end of the neck, said neck also having an exterior surface, wherein the plug of the combination is an interference-fit plug, wherein the plug is releasably mounted over the top end of the neck of the spout body in an interference fit and hermetically seals the product passage of the spout body, which plug has a molded plug body of plastic material, wherein the plug body has a top portion and a downward depending outer annular wall adapted to be fitted over a top section of the tubular neck of the spout, wherein the outer annular wall has an interior surface which forms an annular sealing surface, and wherein the exterior surface of the top section of the neck embodies a cooperating annular sealing surface such that a hermetic seal is present between the outer annular wall of the plug and the neck of the spout body, wherein the exterior of the neck of the spout body, below the top section thereof, is provided with an integrally molded first cap connector formation, wherein the plug is adapted to be removed by the filling machine and to be replaced by pressing the plug onto the neck after filling of the pouch with the flowable product, wherein the cap of the combination is a manually openable cap that is adapted to be assembled on the spouted pouch after the filling of the pouch and the replacing of the plug onto the neck, wherein the cap has a cap body that is injection molded of thermoplastic material, which cap body includes an annular skirt having an interior surface, an exterior surface, and a lower end, wherein a section of the interior of the skirt is provided with an integrally molded second cap connector formation that is adapted to cooperate with the first cap connector formation on the neck of the spout body, and wherein the cap body and the plug body are provided with cooperating snap-fit formations, wherein the cap body and the plug body are embodied such that, with the plug replaced over the top end of the neck, the cap body can be lowered over the plug in a manner causing the first and second cap connector formations to cooperate and causing the snap-fit formations to engage and thereby couple the plug to the cap, wherein the cooperating snap fit formations coupling the plug to the cap are such that upon manually opening of the cap the plug remains coupled to the cap and is entrained with the cap so as to open the product passage and allowing dispensing of the flowable product from the filled pouch, and wherein the cap, below the skirt, is provided with an integrally molded tamper- evident structure that allows to visually evidence the first time opening of the filled pouch, and wherein the spout body, below the first cap connector formation, is provided with one or more integrally molded tamper-evident formations that cooperate with said tamper-evident structure of the cap, such that upon first time opening of the filled pouch the tamper-evident structure evidences said first time opening.
The inventive solution allows for the production of aseptically filled pouches, wherein the user openable cap does not need to be subjected to any sterilizing process. As is preferred, the plug removal, the filling of the pouch with the flowable product, and replacing of the plug are performed in an aseptic environment, whereas the assembly of the cap is preferably done in a non-aseptic environment, e.g. by a capping machine downstream of the filling machine.
This approach is possible as the plug hermetically reseals the filled pouch prior to leaving the aseptic environment.
In a preferred embodiment an aseptic environment is created wherein there is a positive flow of sterilized gas, e.g. of sterilized air. For example the environment is created within a chamber housing the filling machine or a part thereof.
It will be appreciated that the combination can also be used in processes where the placement of the cap does take place within the aseptic environment. This will however demand the sterilization of the cap.
The plug seals on the exterior of the neck. In combination with a suitable filling machine, in particular nozzle thereof, one can achieve the effect that this sealing takes place on a surface of the neck that has not been in contact with the flowable product. Thereby a high quality seal is enhanced. Moreover, in an embodiment of the filling machine, e.g. of the filling nozzle, the filling machine has not touched the sealing surface of the neck where the outer wall of the plug seals onto the neck, so avoiding any chance of this neck sealing surface being scratched or damaged by the filling nozzle or filling machine. For example the nozzle extends into the neck and/or seals onto the top end of the neck, without the filling nozzle touching this external sealing surface for the plug. In another embodiment the filling nozzle may touch the exterior sealing surface of the neck, e.g. with the nozzle sealing onto the very top end of the neck. The latter embodiment may pose additional requirements on the contact face of the nozzle, e.g. the smoothness thereof, and/or on the positioning of the neck relative to the nozzle.
In an embodiment the still empty spouted pouch closed by the plug, yet without the cap being assembled, is or has been subjected to a pre-sterilizing treatment prior to entry into the aseptic environment. For example the empty spouted pouch has been sterilized in said In an embodiment the one or more centering portions of the plug body delimit an open bottom cavity for reception of a pin portion of the plug retention member therein, wherein the one or more centering portions engage on the pin in an interference fit. This, as explained above, allows for high speed operation whilst avoiding undue contact with the annular sealing surface of the plug body.
In an embodiment the centering portion of the plug body comprises an inner annular wall downwardly depending from the top portion of the plug body and coaxial with the outer annular wall, wherein the inner annular wall delimits the open bottom cavity for reception of a pin portion of the plug retention member therein, wherein the inner annular wall engages on the pin in an interference fit.
The present invention also relates to a method for production of aseptically filled spouted pouches with a manually openable cap, which method comprises: - supplying an empty, preferably pre-sterilized, spouted pouch to an aseptic filling machine, which spouted pouch comprises: - a flexible material pouch body, - a spout having a molded spout body of plastic material, said spout body having at a lower end thereof an attachment portion that is attached to the pouch body, wherein said spout body has at an upper end thereof a tubular neck, which neck has an interior surface delimiting at least a section of a product passage that extends from a lower product passage opening through the spout body to a mouth opening at a top end of the neck, said neck also having an exterior surface, - arranging at least the end portion of the neck of the empty spouted pouch in an aseptic environment of the filling machine, - filling, in said aseptic environment, the spouted pouch with a flowable product via the product passage in the spout body,
