The present invention relates to filling packaging. More particularly, the present invention relates to a vacuum filling assembly for filling a packaging having a plurality of cavities with objects, as well as to a corresponding method and system for doing the same.
In the field of packaging for small consumer goods, there exists different ways to fill such packaging which protects the goods during transport, distribution, and sale to the ultimate consumer of the goods. One example of such packaging is the blister pack or blister card, which is a term used for various types of pre-formed plastic packaging.
In the pharmaceutical field, as but one example of a field in which blister packs are used, the pockets of the blister pack are filled with medication, tablets, or pills. The pockets are then sealed so that the tablets are protected from the elements and secured within the pockets. The blister packs can be filled with the tablets using any conventional means.
Often, a professional such as a pharmacist will manually fill each pocket of the blister pack with a corresponding tablet, or with many different tablets for a same dosage period. It can be appreciated that one disadvantage associated with this technique is that it takes a long time to fill all the pockets of the blister pack, especially when filling out a prescription of medication for a long duration. It may further disadvantageously lead to human errors by placing the incorrect tablet in a corresponding pocket.
Other techniques for filling a blister pack exist as well. One example includes the system produced by Synergie Médicate BRG inc., commercialised under the trade-mark SynMed. This automated system eliminates many of the repetitive tasks which must be performed by a user, and employs a suction system. The website for the system (http://www.synmedrx.com) describes it as follows:
Some drawbacks associated with automated systems may include: a) they may be too costly to install or operate for smaller pharmacies; b) they occupy valuable space within a pharmacy; c) they may require complicated migration and installation of information technology to manage and control operations; d) theft operation cannot be easily visually inspected by a pharmacist; e) they can be relatively complicated machines to operate and maintain; and f) etc.
Hence, in light of the aforementioned, there is a need for a device which, by virtue of its design and components, would be able to overcome or at least minimize some of the aforementioned prior art drawbacks.
One object of the present invention is to provide a solution to at least one of the above-mentioned prior art drawbacks.
In accordance with an aspect of the present invention, there is provided a vacuum filling assembly for filling a packaging having a plurality of cavities with objects, the filling assembly comprising:
a handle;
a manifold mounted about the handle for receiving suction;
a valve operatively connected to the manifold and manually operable between a retain configuration wherein the valve is in an open position and suction is supplied to the manifold, and a release configuration wherein the valve is in a closed position and the manifold is free of suction; and
a plurality of prongs in fluid engagement with the manifold and extending therefrom, each prong configured for applying suction to a corresponding object upon the valve being in the retain configuration, thereby retaining the object, and each prong configured for releasing the retained object in a corresponding cavity of the packaging upon the valve being in the release configuration, thereby filling the packaging.
In some embodiments, the manifold is oriented horizontally and has an outlet through which suction is applied and a plurality of inlets, each inlet being in fluid engagement with a corresponding prong. In such an embodiment, the valve can be mounted to the manifold between the outlet and the plurality of inlets.
In some embodiments, the manifold is oriented vertically and has an outlet through which suction is applied and an inlet in fluid engagement with the plurality of prongs. In such an embodiment, the valve is mounted to the manifold between the inlet and the outlet.
In some embodiments, the valve has a cylinder rotatably mounted within the manifold and rotatable between the retain and release configurations, and a tab extending from the cylinder for rotating the cylinder. The valve may also have a push button with a spring.
In some embodiments, the plurality of prongs are mounted to the manifold and spaced apart from one another such that each prong releases an object into a corresponding cavity of the packaging upon the valve being in the release configuration. Optionally, the plurality of prongs are mounted to the manifold and spaced equidistantly from each other along a length of the manifold.
According to another aspect of the present invention, there is provided a method for filling a packaging having a plurality of cavities with objects, the method comprising the steps of:
a) supplying suction to at least one prong;
b) retaining at least one of the objects with the at least one prong via suction;
c) placing the at least one prong and the retained at least one object over a corresponding cavity of the packaging; and
d) releasing the at least one object into the corresponding cavity, thereby filling the packaging.
According to yet another aspect of the present invention, there is provided a system for filling a packaging having a plurality of cavities with objects, comprising:
a container for receiving and containing the objects therein;
a vacuum supply for generating suction; and
a filling assembly comprising:
The components, advantages and other features of the invention will become more apparent upon reading of the following non-restrictive description of some optional configurations, given for the purpose of exemplification only, with reference to the accompanying drawings.
In the following description, the same numerical references refer to similar elements. Furthermore, for the sake of simplicity and clarity, namely so as to not unduly burden the figures with several references numbers, not all figures contain references to all the components and features, and references to some components and features may be found in only one figure, and components and features of the present invention illustrated in other figures can be easily inferred therefrom. The embodiments, geometrical configurations, materials mentioned and/or dimensions shown in the figures are optional, and are given for exemplification purposes only.
Furthermore, although the present invention may be used with various objects, such as pills, for example, and as a result, is sometimes described in the context of the present invention as being use to fill a blister pack with pills, it is understood that it may be used with other objects, and to fill other types of packaging. For this reason, expressions such as “pill”, “medicine”, “pharmacist”, “prescription”, “pharmacy”, etc. as used herein should not be taken as to limit the scope of the present invention to the filling of blister packs and/or medicinal pills in particular. These expressions encompass all other kinds of materials, objects and/or purposes with which the present invention could be used and may be useful, as can be easily understood.
Broadly described, the vacuum filling assembly 10, an example of which is shown in
The filling assembly 10 can be any device, system, or mechanism whose collection of parts allows a packaging 12 to be filled with objects 14. In most embodiments, but not necessarily all, the filling assembly 10 can be manually manipulated by a hand of a user, such as a pharmacist. Alternatively, the filling assembly 10, its components, and/or its operation can be automated. The filling assembly 10 and its components can be made of any suitable material. In some embodiments, the filling assembly 10 and its components are made of plastic, thereby advantageously reducing the weight of the filling assembly and allowing it to be more easily handled.
As will be further explained below, the filling assembly 10 may be held and manipulated by a single hand of the user, thereby advantageously freeing the user's other hand to be used as desired. It may be desirable to fill the packaging 12 for any number of reasons. For example, the packaging 12 could constitute a supply of medicine for a patient, and it is thus desirable to fill the packaging 12 with the prescribed medicine. In another example, it can be desirable to fill a packaging with perishable food objects and to seal the same so as to preserve the perishable food objects.
It can thus be appreciated that the packaging can take any suitable shape or configuration so as to respond to the different types of objects 14 and purposes with which, and for which, the packaging 12 can be filled. The packaging 12 has a plurality of cavities 16 for receiving the objects 14. In the optional embodiment shown in
The filling assembly 10 has a handle 18, an example of which is shown in
The filling assembly 10 also has a manifold 20, an example of which is also shown in
The manifold 20 is mounted about the handle 18 so as to receive suction. The expression “mounted about” refers to the positioning of the manifold 20 with respect to the handle 18 in that the manifold 20 can be mounted directly to, or adjacent with, the handle 18. In the example shown in
The manifold 20 receives suction. The term “suction” refers to the force acting upon the objects 14 due to the pressure difference between the interior of the manifold 20 and the surrounding environment. For example, in most embodiments, the vacuum supply will cause the manifold 20 to have a lower pressure than atmosphere. This will cause air to be drawn into the manifold 20, thereby producing the suction, or force, which retains the objects 14 against the prongs, as further explained below. The manifold 20 may thus form a closed or sealed connection with the vacuum supply so as to advantageously improve the suction applied to the objects 14.
The filling assembly 10 also includes a valve 30, an example of which is shown in
This link between the valve 30 and the manifold 20 can therefore take many different forms and configurations. In the example shown in
The valve 30 can be operated between two configurations: a retain configuration and a release configuration. In the retain configuration, the valve 30 is in an open position and the suction is supplied In the manifold 20, and thus to the prongs. The expression “open position” refers to the orientation of the valve 30 and/or one of its components such that the suction can be transmitted to, and received in, the manifold 20. In the release configuration, the valve 30 is in a closed position and the manifold 20 does not receive any suction. The expression “closed position” refers to the orientation of the valve 30 and/or one of its components such that the suction is no longer received in the manifold 20, and thus no longer acts on the objects 14. In some embodiments, the force acting on the objects 14 can be varied by operating the valve 30 between the open and closed positions, thereby advantageously allowing the user to adjust the suction as required.
In some embodiments, examples of which are shown in
The filing assembly 10 also includes a plurality of prongs 40, examples of which are also shown in
In most embodiments, but not necessarily all, each prong 40 is a hollow and elongated part which extends away from the manifold 20. Each prong 40 has a first end 42 which applies the suction to the object 14 and is in contact therewith. Each prong 40 also has a second end 44 in fluid engagement with the manifold 20. The shape and configuration of each prong 40 can vary. In some embodiments, each prong 40 can be a nozzle, which may advantageously allow the suction to be applied to the object 14 more efficiently. The size and configuration of the first end 42 can vary depending on numerous factors such as, but not limited to: the nature of the objects 14 to be retained; the available suction to be applied, the nature of the cavities 16 into which the objects 14 are released, etc.
Each prong 40 is in fluid engagement with the manifold 20. The expression “fluid engagement” refers to the ability of the each prong 40 to receive the suction supplied by the manifold 20, and to apply that suction against corresponding one or more objects 14. In most embodiments, the hollow nature of each prong 40 allows the fluid (e.g. air) to flow freely between the outside of the prong 40, through the body of the prong 40, and into the manifold 20.
The operation of each prong 40 may be as follows. When the valve 30 is in the retain configuration (i.e. the valve 30 is in the open position), fluid is drawn through the body of the prong 40 and into the manifold 20, thereby generating suction. The prong 40 can therefore apply the suction to a corresponding object 14, thereby retaining the object 14. When the valve 30 is in the release configuration (i.e. the valve is in the closed position), fluid is prevented from being drawn through the body of the prong 40 and into the manifold 20, and suction cannot therefore be produced. The object 14 which was being retained by the prong 40 can therefore be released into a cavity 16 of the packaging 12, thereby filling the packaging 12. The object 14 can also be released by the prong 40 when the suction applied to the object 14 is not sufficient to retain it against the prong 40.
In some embodiments, the prongs 40 are mounted to the manifold 20 and spaced apart from one another so that each prong 40 can release the object 14 it retains directly into a corresponding cavity 16 of the packaging 12 when the valve 30 is in the release configuration. This optional configuration is shown in
In some embodiments, the orientation of the manifold 20, and thus of the filling assembly 10, can be varied so as to be better adapted to the ergonomic needs of the user.
In the embodiment exemplified in
In the embodiment exemplified in
According to another aspect, there is provided a system 50 for filling the cavities 16 of a packaging 12 with objects 14, an example of which is shown in
The system 50 has a container 52, which can take any suitable shape or form, and which can be made of any suitable material (e.g. plastics, metals, etc.). The container 52 receives and contains the objects 14 which are intended to fill the cavities 16 of the packaging. The prongs 40 of the filling assembly 10 can thus retrieve and retain the objects 14 from the container 52. The system 50 also has a vacuum supply 54. The vacuum supply 54 can be any suitable pump, generator, or motor in fluid engagement with the fluid assembly 10 so as to draw fluid (e.g. air) from the fluid assembly 10 so as to generate the suction required to retain the objects 14. The system 50 also has at least one filling assembly 10, such as the one described above.
In some embodiments, the system 50 includes one or more filling assemblies 10, each one of which is in fluid engagement with the vacuum supply 54. This embodiment can advantageously allow one operation, such as a pharmacy, to provide each of its users (e.g. pharmacists) with their own filling assembly 10, thereby advantageously increasing their efficiency. It can thus be appreciated that the system 50 can be portable so as to set up wherever required (e.g. field hospital, pharmacy, indoors, outdoors, etc.).
According to another aspect, and referring to
The method includes the step of supplying suction to one or more prongs 40. The suction can be supplied by activating a vacuum supply 54, as explained above, which draws air through the prongs 40, thereby creating the suction.
The method also includes the step of retaining at least one of the objects 14 with one or more prongs 40 via suction. This step may be performed when the user, a pharmacist for example, receives the prescription from the patient. In order to fill the prescription, the pharmacist can supply the suction to the prongs 40 so that they retain the objects 14 (e.g. pills) with the prongs 40.
The method also includes the step of placing the one or more prongs 40, with the objects 14 being retained by them, over the cavities 16 of the packaging 12. Continuing with the example of a pharmacist user, once she has retained the objects 14 via suction, she can release or deposit them in the cavities 16 of the blister pack, for example. This is achieved by placing the prongs 40 over the corresponding cavities 16.
The method also includes the step of releasing the one or more objects 14 into the cavities 16 of the packaging 12, thereby filling the packaging 12. The releasing of the objects 14 from the prongs 40 can be performed using different techniques. In some embodiments, the user can stop the supply of suction to the one or more prongs 40, thereby causing the objects 14 to fall into the cavities 16 via gravity. In some embodiments, the user can impart a force to the objects 14 so that they are removed from the prongs 40 and fall into the cavities 16.
In light of the preceding, it can be appreciated that the present invention can provide advantages in that, by virtue of its design and components, the filling assembly 10, system 50, and method may provide a simple, manually-operable, and affordable technique for assisting users, such as pharmacists, to better fill packaging with the objects. In so doing, the present invention helps to reduce the complexity and difficulty associated with filling a prescription, for example, further improving the efficiency of its users.
Moreover, the handle 18 provides an ergonomic and easy to grip surface for holding the filling assembly 10 both before and during its operation. The manifold 20 may also allow for more efficient generation and distribution of the suction produced by the vacuum supply 54.
Furthermore, the valve 30 allows for a relatively simple and easy control of the suction provided to the prongs 40, and can be relatively easily manipulated by only one of the user's hands. This manipulability advantageously may allow the user to more easily retain and release the objects 14.
In add on, the prongs 40 allow for many objects 14, and many different types of objects 14, to be retained in a single pass. Such efficiency may allow a user to fill more packages per unit of time, thereby increasing her efficiency.
In another embodiment of the present invention, as shown in
As better shown in
Hence, the above-described adapter can be used when the prongs of the filling assembly are designed to retain standard-sized pills for example but then the user wishes to use the assembly with smaller-sized pills. The adapter can thus be easily installed and removed when manipulating differently sized pills.
Of course, numerous modifications could be made to the above-described embodiments without departing from the scope of the invention, as defined in the appended claims.
