Definitions
- the present invention relates to a container and, in particular, to a collapsible container that is capable of containing a concentrated product.
- collapsible containers have been in the form of a collapsible tube which defines a single chamber.
- a container including a storage chamber within which is located at least one concentrated product; a mixing chamber coupled to the storage chamber; and a closure element, wherein the storage chamber is isolated from the mixing chamber; the mixing chamber is defined by a body having a longitudinal length defined between opposed ends and along at least a portion of the length of the mixing chamber, the body defines circular bellows, such that the mixing chamber has a collapsed configuration when the ends of the body are urged together and an expanded configuration when the ends of the body are urged apart; and wherein a first end of the mixing chamber is open and is selectively closable via the closure element.
- the container of the invention defines two separate chambers: a storage chamber within which at least one concentrated product may be located; and a mixing chamber within which the concentrated product may be mixed with a diluent, such as water.
- the circular bellows of the mixing chamber permit the container to be configured in a collapsed configuration when there is little or no diluent in the mixing chamber. This makes the container easier to store and transport. However, when it is desired to dilute the concentrated product, the mixing chamber may be expanded to receive the desired volume of diluent.
- the shelf life of the concentrated product may be significantly increased compared to a concentrated product simply located within the mixing chamber. This is because the polymeric material from which the mixing chamber may be formed in order to permit the collapsing and the expansion of the mixing chamber via its circular bellows may not provide optimum protection for the concentrated product against spoiling. In contrast, the storage chamber within which the concentrated product is located may provide the desired protection against spoiling without interfering with the operation of the container.
- the circular bellows of the mixing chamber increases the agitation when the diluent is added to the concentrated product, which aids the mixing of the concentrated product with the diluent.
- the concentrated product may be in the form of a liquid, a gel or a solid, such as a powder or a tablet.
- the diluent is suitably water.
- the mixing chamber is suitably defined by a mixing chamber body.
- the circular bellows suitably include a latching arrangement which acts to latch the bellows in its collapsed and/or expanded configuration.
- the latching arrangement resists the movement of the bellows.
- the force exerted by the latching arrangement is greater than a stored force within the bellows which would otherwise urge the bellows out of its collapsed and/or expanded configuration.
- the latching arrangement does not prevent movement of the bellows. Instead, the latching force exerted by the latching arrangement must first be removed or overcome in order to move the bellows against the latching force.
- the mixing chamber is detachably coupled to the storage container.
- the storage chamber may be screwed onto the mixing chamber or it may be snap-fit to the mixing chamber.
- the mixing chamber and the storage container may include a threaded coupling or a snap-fit coupling.
- the closure element defines a well which is configured to receive a housing or container which contains the concentrated product.
- the closure element suitably includes an internally facing surface and an externally facing surface and the well may be open at the externally facing surface.
- the well may be an open well or it may include a closable lid.
- the well may define the storage chamber or it may define a holding chamber separate to the storage chamber.
- the storage chamber may be defined by a storage chamber body.
- the storage chamber may be defined within the closure element.
- the body may be separate from the closure element.
- the storage chamber body may be coupled to the second end of the mixing chamber (i.e. the end of the mixing chamber which is opposite to the first end).
- the coupling between storage chamber body and the mixing chamber may be a releasable or reversible coupling, such as a threaded coupling or a snap-fit coupling. This permits the mixing chamber to be filled with a diluent without having to remove the storage chamber body from the mixing chamber.
- the second end of the mixing chamber may be closed.
- closed means that the relative end forms a liquid-tight seal with the mixing chamber body, for example, by the mixing chamber body, including the closed end, being formed by a continuous layer of moulded polymeric material.
- the storage chamber need have no sealing function in respect of the mixing chamber. Accordingly, the storage chamber body need not form a liquid-tight seal with the mixing chamber when coupled thereto.
- the storage chamber body may define a closable opening for access to the storage chamber and the concentrated product located therein.
- the closable opening may be defined at any suitable location of the storage chamber body.
- the second end of the mixing chamber may be open. This makes the manufacture of the mixing chamber slightly easier and the cost of the mixing chamber slightly lower, but means that the storage chamber body must form a liquid-tight seal when coupled to the second end of the mixing chamber.
- the mixing chamber body may include a sealing wall which closes the second end of the mixing chamber when the storage chamber body is coupled thereto; and the storage chamber body defines a closable opening.
- the opening is suitably separate from the sealing wall, such that opening does not compromise the seal generated by the sealing wall.
- Examples of such embodiments include (i) the storage chamber defining a tubular side wall having a proximal end wall which is adjacent to the mixing chamber in use and a distal end wall opposite to the proximal end wall; wherein the closable opening is defined in the proximal end wall and the sealing wall is formed by the distal end wall; and (ii) the storage chamber defining a tubular side wall having a proximal end wall which is adjacent to the mixing chamber in use and a distal end wall opposite to the proximal end wall; wherein the closable opening is defined in the distal end wall and the sealing wall is formed by the proximal end wall.
- any failure of the opening would simply result in the concentrated product(s) entering the mixing chamber, and as such, they would not be lost. Additionally, this arrangement permits the tubular side wall to extend into a bottom portion of the mixing chamber, which results in a more compact arrangement compared to embodiments in which the storage chamber is entirely located outside of the mixing chamber.
- the storage chamber body needs to be removed from the mixing chamber to access the concentrated product within the storage chamber.
- the storage chamber body needs to be removed from the mixing chamber to access the concentrated product within the storage chamber.
- the interior of the storage chamber can be accessed without needing to remove the storage chamber body from the mixing chamber.
- the storage chamber may be defined by the closure element or it may be carried by the closure element.
- the storage chamber may be defined within the closure element.
- the second end of the mixing chamber is suitably closed.
- the closure element may define a tubular side wall having a top end and a bottom end opposite to the top end; wherein the side wall, top end and bottom end together define the storage chamber; and wherein a closable opening is defined in the bottom end.
- top and bottom refer to the container when oriented in a substantially vertical orientation with the closure element located at the top of the mixing chamber.
- the interior of the chamber may only be accessed when the closure element has been removed from the mixing chamber. Additionally, it permits a more compact arrangement, as the tubular side wall may extend wholly or partially into the interior of the mixing chamber.
- the closure element defines a tubular side wall having a top end and a bottom end opposite to the top end; wherein the side wall, top end and bottom end together define the storage chamber; and wherein a closable opening is defined in the top end.
- the interior of the storage chamber may be accessed without removing the closure element from the mixing chamber.
- the closure element is suitably releasably secured to the mixing chamber via a threaded coupling.
- the mixing chamber is suitably in the form of a substantially tubular body.
- the storage chamber contains one or more concentrated products, wherein each concentrated product is stored within a respective housing.
- the storage chamber may contain a plurality of separate concentrated products, each stored within a respective housing.
- the housings are suitable sealed against the ingress of gases and liquids.
- the circular bellows may be defined by a series of circular bellows wall sections (i.e. a plurality of bellows wall sections arranged in a longitudinal array), wherein each circular bellows wall section includes a first wall portion and a second wall portion; the first and second wall portions are conical sections which are angled relative to each other; the first and second wall portions extend outwardly from the longitudinal axis of the mixing chamber and together define a V-shape; the connection between the first and second wall portions forms an outer return portion; and adjacent bellows wall sections are connected via inner return portions.
- each circular bellows wall section includes a first wall portion and a second wall portion; the first and second wall portions are conical sections which are angled relative to each other; the first and second wall portions extend outwardly from the longitudinal axis of the mixing chamber and together define a V-shape; the connection between the first and second wall portions forms an outer return portion; and adjacent bellows wall sections are connected via inner return portions.
- V-shaped is to be understood to a sideways V, in other words the outer return is “>”-shaped.
- each bellows wall section may range from 0° to 180°. However, this angle is suitably from 0° to 120°, 110°, 100° or 90°.
- This arrangement of the bellows wall sections permits the maximum expansion and collapse of the bottle while maintaining a desired level of mechanical strength and resistance to cracking.
- the inner return portions may include an arcuate connecting portion.
- a first or second wall portion of a bellows wall section is connected to a second or first wall portion of a neighbouring (i.e. adjacent) bellows wall section via an arcuate connecting body, such as a semi-circular connecting body.
- an arcuate connecting body such as a semi-circular connecting body.
- the second wall portion may be shorter than the first wall portion in each of the bellows wall sections.
- the arrangement causes an “over-centre” arrangement when the mixing chamber is moved to its collapsed configuration, which in turn latches the circular bellows in their collapsed configuration.
- a latching mechanism is formed by second wall portions being shorter than the first wall portions, resulting in an over-centre arrangement of the inner return portions in the collapsed configuration.
- the over-centre arrangement results when an inner return portion located between a pair of outer return portions is displaced longitudinally during the compression of the mixing chamber such that after compression, the inner return portion has been displaced vertically above or below both of the pair of outer return portions either side of the inner return portion (on the basis that the mixing chamber is collapsed in a vertical direction).
- This “over-centre” arrangement generates latching forces in the circular bellows portion that are typically greater than the restorative forces stored in the return portions as a result of the collapsing of the mixing chamber and therefore prevents or resists the restorative forces urging the mixing chamber back to its expanded configuration.
- the mixing chamber when the mixing chamber is urged into its collapsed configuration, it will typically remain in that configuration until it is urged into its expanded configuration.
- the expansion force exerted on the mixing chamber will overcome the latching forces of the bellows wall sections.
- a container including a storage chamber within which is located at least one concentrated product housed; a mixing chamber coupled to the storage chamber; and a closure element, wherein the storage chamber is isolated from the mixing chamber; the mixing chamber is defined by a body having a longitudinal length defined between opposed ends and along at least a portion of the length of the mixing chamber, the body defines circular bellows, such that the mixing chamber has a collapsed configuration when the ends of the body are urged together and an expanded configuration when the ends of the body are urged apart, the bellows further including a latching arrangement which acts to latch the bellows in their collapsed configuration and/or their expanded configuration; and wherein a first end of the mixing chamber is open and is selectively closable via the closure element.
- a container according to definition 9 wherein the storage chamber defines a tubular side wall having a proximal end which is adjacent to the mixing chamber in use and a distal end opposite to the proximal end; and wherein the closable opening is defined at the proximal end and the sealing wall is located at the distal end.
- a container according to definition 1 3 wherein at least a portion of the storage chamber extends into the mixing chamber when the closure element is coupled to the mixing chamber.
- each bellows wall section includes a first wall portion and a second wall portion; the first and second wall portions are conical sections which are angled relative to each other; the first and second wall portions extend outwardly from the longitudinal axis of the mixing chamber and together define a V-shape; the connection between the first and second wall portions forms an outer return portion; and adjacent bellows wall sections are connected via inner return portions.

- FIGS. 1 a , 1 b and 1 c show components of a container according to a first embodiment of the invention.
- the container comprises a mixing chamber 4 (shown in FIG. 1 a ) which is generally tubular in shape and which is open at both ends 6 , 8 .
- the mixing chamber 4 is blow-molded from a polymeric material.
- the mixing chamber 4 includes a central circular bellows 10 , wherein the circular bellows 10 is formed from a number of bellows wall sections, which, in turn are formed from first conical wall portions 12 , second conical wall portions 14 and outer return portions 16 .
- the length of the first conical wall portions 12 is greater than the length of the second conical wall portions 14 .
- Each bellows wall section is connected to adjacent or neighbouring bellows wall sections via respective inner return portions 18 .
- the bellows wall sections are shown in more detail in FIG. 2 a .
- the inner return portions 18 include a semi-circular connecting portion, which prevents or minimises the deformation of the polymeric material beyond its elastic limit.
- FIG. 1 b shows a detachable closure element 20 in the form of a screw-on lid.
- the lid includes a downwardly extending skirt 22 , which defines a threaded portion (not shown) on the inwardly facing wall of the skirt 22 .
- the top end 6 of the mixing chamber 4 carries a complementary threaded portion 24 , such that the closure element 20 may be screwed onto or unscrewed from the open top end 6 of the mixing chamber 4 .
- FIG. 1 c shows a storage chamber defined by a storage chamber body 26 .
- the storage chamber body 26 includes a cylindrical side wall 28 , a closed bottom wall (not shown) and an upwardly extending skirt 30 .
- the skirt 30 defines a threaded portion (not shown) on its inwardly facing wall.
- the bottom end 8 of the mixing chamber 4 carries a complementary threaded portion 32 , such that the storage chamber body 26 may be screwed onto or unscrewed from the open bottom end 8 of the mixing chamber 4 .
- a top wall of the storage chamber body 26 defines an opening 33 to provide access to the interior of the storage chamber, and the opening 33 is closed via a removable sealing film 34 .
- the sealing film 34 is adhered or welded to a peripheral portion of the top wall which defines the opening 33 .
- FIG. 2 a shows a section of the circular bellows 10 in an expanded configuration.
- the angle between the first conical wall portion 12 and the second conical wall portion 14 at the outer return portion 16 is about 90°.
- the angle between adjacent second conical wall portions 14 and first conical wall portions 12 at the inner return portion 18 is about 80°.
- FIG. 2 b shows the over-centre arrangement of the first and second wall portions 12 , 14 in the collapsed configuration.
- the dashed line A in FIGS. 2 a and 2 b projects through a common point (an outer return portion 16 ).
- both of the inner return portions 18 are displaced vertically upwards as the mixing chamber 4 is collapsed until both of these inner return portions are located above the dashed line A.
- the displacement of the inner return portion 18 such that it lies outside of the cylindrical region defined between the two adjacent outer return portions 16 is referred to herein as an “over-centre” arrangement.
- Such an arrangement generates a latching force at each of the inner return portions 18 which are greater than the restorative forces that are stored in the return portions when the mixing chamber 4 is collapsed. Accordingly, the latching forces resist or prevent the expansion of the mixing chamber towards is expanded configuration.
- FIG. 3 shows the container in its collapsed configuration. This is the typical configuration for storage or transportation of the container.
- the user first unscrews the storage chamber body 26 from the mixing chamber 4 . This releases the air tight seal between the storage chamber body 26 and the mixing chamber 4 and prevents the generation of a partial vacuum within the mixing chamber during expansion.
- the mixing chamber is then expanded by urging the two end 6 , 8 apart. Once expanded, the sealing film 34 is removed to expose the powdered concentrate product located within the storage chamber.
- the storage chamber body 26 is then screwed back onto the mixing chamber 4 .
- the closure element 20 is then unscrewed from the top 6 of the mixing chamber 4 and a diluent (such as water) is added to the mixing chamber via the open end 6 of the mixing chamber 4 .
- a diluent such as water
- the closure element 20 is then screwed back onto the top end 6 of the mixing chamber 4 and the concentrated powdered product is mixed with the diluent, for example with agitation or shaking.
- the circular bellows arrangement aids with the mixing of the concentrated powdered product and the diluent.
- the concentrated product within the storage chamber defined by the storage chamber body 26 may be in the form of a liquid, paste or gel, instead of a powder.
- FIGS. 4 and 5 show alternative embodiments of the invention in which the mixing chamber 4 and the closure element 20 are as described above in connection with FIGS. 1 to 3 , but the storage chamber is different.
- a storage chamber body 40 includes a cylindrical side wall 42 , an upwardly extending skirt 44 , and a closed, gas-tight and liquid-tight top wall 46 .
- a bottom wall 48 of the storage chamber body 40 defines an opening 50 and includes a detachable base 52 which is arranged to form a snap-fit with the bottom wall 48 . In this way, the opening may be selectively closed or opened via the detachable base 52 .
- the detachable base 52 may include a circular aperture through which a user's finger may be located to permit a downward force to be exerted on the detachable base 52 .
- the concentrated product is located within a separate sealed housing 54 which includes an opening at its upper end that is sealed with a sealing film 56 .
- FIG. 5 shows a similar arrangement to that shown in FIG. 4 and described above, except that the cylindrical side wall is longer and a plurality of sealed housings 60 containing separate concentrated products are located within the storage chamber defined by the storage chamber body.
- the concentrated products in the sealed housings 60 may be the same or different. All other features of the storage chamber body are as described above in connection with FIG. 4 .
- the user removes the closure element from the top of the mixing chamber and expands the mixing chamber as described above.
- the detachable base is then removed from bottom wall and the or one of the individually sealed housings are removed from the storage chamber.
- the sealing film is then removed from the housing and the concentrated product is emptied into the mixing chamber.
- a diluent, such as water is then added to the mixing chamber, the closure element is then screwed back onto the top open end of the mixing chamber and the concentrated product mixed with the diluent.

Description
- This application is a divisional of U.S. patent application Ser. No. 16/893,596 filed Jun. 5, 2020 and entitled “A Container”, which itself claims the benefit of priority based on United States Provisional Patent Application Ser. No. 62/859,973, filed Jun. 11, 2019 and entitled “A Container”, the contents of each of which being incorporated herein in their entireties.
- The present invention relates to a container and, in particular, to a collapsible container that is capable of containing a concentrated product.
- Collapsible containers are known and are described, for example, in U.S. Pat. Nos. 4,773,458; 4,955,493; and 4,492,313.
- However, the known collapsible containers have been in the form of a collapsible tube which defines a single chamber.
- According to a first aspect of the invention, there is provided a container including a storage chamber within which is located at least one concentrated product; a mixing chamber coupled to the storage chamber; and a closure element, wherein the storage chamber is isolated from the mixing chamber; the mixing chamber is defined by a body having a longitudinal length defined between opposed ends and along at least a portion of the length of the mixing chamber, the body defines circular bellows, such that the mixing chamber has a collapsed configuration when the ends of the body are urged together and an expanded configuration when the ends of the body are urged apart; and wherein a first end of the mixing chamber is open and is selectively closable via the closure element.
- The container of the invention defines two separate chambers: a storage chamber within which at least one concentrated product may be located; and a mixing chamber within which the concentrated product may be mixed with a diluent, such as water.
- The circular bellows of the mixing chamber permit the container to be configured in a collapsed configuration when there is little or no diluent in the mixing chamber. This makes the container easier to store and transport. However, when it is desired to dilute the concentrated product, the mixing chamber may be expanded to receive the desired volume of diluent.
- By storing the concentrated product in the storage chamber, the shelf life of the concentrated product may be significantly increased compared to a concentrated product simply located within the mixing chamber. This is because the polymeric material from which the mixing chamber may be formed in order to permit the collapsing and the expansion of the mixing chamber via its circular bellows may not provide optimum protection for the concentrated product against spoiling. In contrast, the storage chamber within which the concentrated product is located may provide the desired protection against spoiling without interfering with the operation of the container.
- Furthermore, the circular bellows of the mixing chamber increases the agitation when the diluent is added to the concentrated product, which aids the mixing of the concentrated product with the diluent.
- In the context of the present invention, the concentrated product may be in the form of a liquid, a gel or a solid, such as a powder or a tablet. Furthermore, the diluent is suitably water.
- The mixing chamber is suitably defined by a mixing chamber body.
- The circular bellows suitably include a latching arrangement which acts to latch the bellows in its collapsed and/or expanded configuration. It will be understood that in the context of the subject invention, the latching arrangement resists the movement of the bellows. In other words, the force exerted by the latching arrangement is greater than a stored force within the bellows which would otherwise urge the bellows out of its collapsed and/or expanded configuration. The latching arrangement does not prevent movement of the bellows. Instead, the latching force exerted by the latching arrangement must first be removed or overcome in order to move the bellows against the latching force.
- In an embodiment of the invention, the mixing chamber is detachably coupled to the storage container. For example, the storage chamber may be screwed onto the mixing chamber or it may be snap-fit to the mixing chamber. As such, the mixing chamber and the storage container may include a threaded coupling or a snap-fit coupling.
- In an embodiment of the invention, the closure element defines a well which is configured to receive a housing or container which contains the concentrated product. The closure element suitably includes an internally facing surface and an externally facing surface and the well may be open at the externally facing surface. The well may be an open well or it may include a closable lid. The well may define the storage chamber or it may define a holding chamber separate to the storage chamber.
- In one embodiment of the invention, the storage chamber may be defined by a storage chamber body. In an alternative embodiment, the storage chamber may be defined within the closure element. In embodiments in which the storage chamber is defined by a storage chamber body, the body may be separate from the closure element.
- In embodiments in which the storage chamber is defined by a storage chamber body, the storage chamber body may be coupled to the second end of the mixing chamber (i.e. the end of the mixing chamber which is opposite to the first end). The coupling between storage chamber body and the mixing chamber may be a releasable or reversible coupling, such as a threaded coupling or a snap-fit coupling. This permits the mixing chamber to be filled with a diluent without having to remove the storage chamber body from the mixing chamber.
- The second end of the mixing chamber may be closed. It will be appreciated in the context of the subject invention that the term “closed” means that the relative end forms a liquid-tight seal with the mixing chamber body, for example, by the mixing chamber body, including the closed end, being formed by a continuous layer of moulded polymeric material. This means that the storage chamber need have no sealing function in respect of the mixing chamber. Accordingly, the storage chamber body need not form a liquid-tight seal with the mixing chamber when coupled thereto.
- In such embodiments (second end of the mixing chamber is closed), the storage chamber body may define a closable opening for access to the storage chamber and the concentrated product located therein. The closable opening may be defined at any suitable location of the storage chamber body.
- Alternatively, the second end of the mixing chamber may be open. This makes the manufacture of the mixing chamber slightly easier and the cost of the mixing chamber slightly lower, but means that the storage chamber body must form a liquid-tight seal when coupled to the second end of the mixing chamber.
- In embodiments in which the second end of the mixing chamber is open, the mixing chamber body may include a sealing wall which closes the second end of the mixing chamber when the storage chamber body is coupled thereto; and the storage chamber body defines a closable opening. The opening is suitably separate from the sealing wall, such that opening does not compromise the seal generated by the sealing wall. Examples of such embodiments include (i) the storage chamber defining a tubular side wall having a proximal end wall which is adjacent to the mixing chamber in use and a distal end wall opposite to the proximal end wall; wherein the closable opening is defined in the proximal end wall and the sealing wall is formed by the distal end wall; and (ii) the storage chamber defining a tubular side wall having a proximal end wall which is adjacent to the mixing chamber in use and a distal end wall opposite to the proximal end wall; wherein the closable opening is defined in the distal end wall and the sealing wall is formed by the proximal end wall.
- In the embodiments in which the closable opening is defined within the proximal end wall, any failure of the opening would simply result in the concentrated product(s) entering the mixing chamber, and as such, they would not be lost. Additionally, this arrangement permits the tubular side wall to extend into a bottom portion of the mixing chamber, which results in a more compact arrangement compared to embodiments in which the storage chamber is entirely located outside of the mixing chamber.
- However, in such embodiments, the storage chamber body needs to be removed from the mixing chamber to access the concentrated product within the storage chamber. Alternatively, by forming the closable opening in the distal end wall of the storage chamber body and having the proximal wall form the sealing wall, the interior of the storage chamber can be accessed without needing to remove the storage chamber body from the mixing chamber.
- As noted above, the storage chamber may be defined by the closure element or it may be carried by the closure element. For example, the storage chamber may be defined within the closure element. In such embodiments, the second end of the mixing chamber is suitably closed.
- The closure element may define a tubular side wall having a top end and a bottom end opposite to the top end; wherein the side wall, top end and bottom end together define the storage chamber; and wherein a closable opening is defined in the bottom end.
- The skilled person will understand that reference to “top” and “bottom” refer to the container when oriented in a substantially vertical orientation with the closure element located at the top of the mixing chamber.
- By locating the closable opening in the bottom end of the storage chamber, the interior of the chamber may only be accessed when the closure element has been removed from the mixing chamber. Additionally, it permits a more compact arrangement, as the tubular side wall may extend wholly or partially into the interior of the mixing chamber.
- In alternative embodiments, the closure element defines a tubular side wall having a top end and a bottom end opposite to the top end; wherein the side wall, top end and bottom end together define the storage chamber; and wherein a closable opening is defined in the top end. In this arrangement, the interior of the storage chamber may be accessed without removing the closure element from the mixing chamber.
- The closure element is suitably releasably secured to the mixing chamber via a threaded coupling.
- The mixing chamber is suitably in the form of a substantially tubular body.
- In an embodiment of the invention, the storage chamber contains one or more concentrated products, wherein each concentrated product is stored within a respective housing. For example, the storage chamber may contain a plurality of separate concentrated products, each stored within a respective housing. The housings are suitable sealed against the ingress of gases and liquids.
- The circular bellows may be defined by a series of circular bellows wall sections (i.e. a plurality of bellows wall sections arranged in a longitudinal array), wherein each circular bellows wall section includes a first wall portion and a second wall portion; the first and second wall portions are conical sections which are angled relative to each other; the first and second wall portions extend outwardly from the longitudinal axis of the mixing chamber and together define a V-shape; the connection between the first and second wall portions forms an outer return portion; and adjacent bellows wall sections are connected via inner return portions.
- The skilled person will appreciate that reference to “V-shaped” is to be understood to a sideways V, in other words the outer return is “>”-shaped. In this way, as the container is collapsed, the angle between first and second wall portions of each bellows wall section will decrease and as the container is expanded, the angle between the first and second wall portions of each bellows wall section will increase.
- The skilled person will understand that the angle between the first and second wall portions of each bellows wall section may range from 0° to 180°. However, this angle is suitably from 0° to 120°, 110°, 100° or 90°.
- This arrangement of the bellows wall sections permits the maximum expansion and collapse of the bottle while maintaining a desired level of mechanical strength and resistance to cracking.
- The inner return portions may include an arcuate connecting portion. In other words, a first or second wall portion of a bellows wall section is connected to a second or first wall portion of a neighbouring (i.e. adjacent) bellows wall section via an arcuate connecting body, such as a semi-circular connecting body. Without wishing to be bound by theory, it is believed that the arcuate connecting portion is more resistant to cracking and permits the adjacent wall portions to hinge relative to each other with less strain. This may be because the bottle material is not weakened at the inner return portions by fracturing as the plastic material is not deformed beyond its elastic limit.
- In such embodiments, the second wall portion may be shorter than the first wall portion in each of the bellows wall sections. The arrangement causes an “over-centre” arrangement when the mixing chamber is moved to its collapsed configuration, which in turn latches the circular bellows in their collapsed configuration. Thus, in such embodiments, a latching mechanism is formed by second wall portions being shorter than the first wall portions, resulting in an over-centre arrangement of the inner return portions in the collapsed configuration. The over-centre arrangement results when an inner return portion located between a pair of outer return portions is displaced longitudinally during the compression of the mixing chamber such that after compression, the inner return portion has been displaced vertically above or below both of the pair of outer return portions either side of the inner return portion (on the basis that the mixing chamber is collapsed in a vertical direction). This “over-centre” arrangement generates latching forces in the circular bellows portion that are typically greater than the restorative forces stored in the return portions as a result of the collapsing of the mixing chamber and therefore prevents or resists the restorative forces urging the mixing chamber back to its expanded configuration.
- Accordingly, when the mixing chamber is urged into its collapsed configuration, it will typically remain in that configuration until it is urged into its expanded configuration. The expansion force exerted on the mixing chamber will overcome the latching forces of the bellows wall sections.
- Further embodiments of the invention are set out in the following definitions:

FIGS. 1a, 1b and 1c show components of a container according to a first embodiment of the invention. The container comprises a mixing chamber 4 (shown inFIG. 1a ) which is generally tubular in shape and which is open at both ends 6, 8. The mixing chamber 4 is blow-molded from a polymeric material. The mixing chamber 4 includes a central circular bellows 10, wherein the circular bellows 10 is formed from a number of bellows wall sections, which, in turn are formed from firstconical wall portions 12, secondconical wall portions 14 andouter return portions 16. The length of the firstconical wall portions 12 is greater than the length of the secondconical wall portions 14. - Each bellows wall section is connected to adjacent or neighbouring bellows wall sections via respective
inner return portions 18. The bellows wall sections are shown in more detail inFIG. 2a . Theinner return portions 18 include a semi-circular connecting portion, which prevents or minimises the deformation of the polymeric material beyond its elastic limit. -
FIG. 1b shows adetachable closure element 20 in the form of a screw-on lid. The lid includes a downwardly extendingskirt 22, which defines a threaded portion (not shown) on the inwardly facing wall of theskirt 22. The top end 6 of the mixing chamber 4 carries a complementary threadedportion 24, such that theclosure element 20 may be screwed onto or unscrewed from the open top end 6 of the mixing chamber 4. -
FIG. 1c shows a storage chamber defined by astorage chamber body 26. Thestorage chamber body 26 includes acylindrical side wall 28, a closed bottom wall (not shown) and an upwardly extendingskirt 30. Theskirt 30 defines a threaded portion (not shown) on its inwardly facing wall. Thebottom end 8 of the mixing chamber 4 carries a complementary threadedportion 32, such that thestorage chamber body 26 may be screwed onto or unscrewed from the openbottom end 8 of the mixing chamber 4. A top wall of thestorage chamber body 26 defines anopening 33 to provide access to the interior of the storage chamber, and theopening 33 is closed via aremovable sealing film 34. The sealingfilm 34 is adhered or welded to a peripheral portion of the top wall which defines theopening 33. - The container is assembled by screwing the
storage chamber body 26 to the openbottom end 8 of the mixing chamber 4 and by screwing theclosure element 20 to the open top end of the mixing chamber 4. A concentrated product (not shown), for example a flavoured powder for forming a flavoured drink, is located within the sealedstorage chamber 26. -
FIG. 2a shows a section of the circular bellows 10 in an expanded configuration. As can be seen, the angle between the firstconical wall portion 12 and the secondconical wall portion 14 at theouter return portion 16 is about 90°. As the secondconical wall portion 14 is shorter than the firstconical wall portion 12, the angle between adjacent secondconical wall portions 14 and firstconical wall portions 12 at theinner return portion 18 is about 80°. -
FIG. 2b shows the over-centre arrangement of the first andsecond wall portions FIGS. 2a and 2b projects through a common point (an outer return portion 16). As can be seen inFIG. 2b , both of theinner return portions 18 are displaced vertically upwards as the mixing chamber 4 is collapsed until both of these inner return portions are located above the dashed line A. The displacement of theinner return portion 18 such that it lies outside of the cylindrical region defined between the two adjacentouter return portions 16 is referred to herein as an “over-centre” arrangement. Such an arrangement generates a latching force at each of theinner return portions 18 which are greater than the restorative forces that are stored in the return portions when the mixing chamber 4 is collapsed. Accordingly, the latching forces resist or prevent the expansion of the mixing chamber towards is expanded configuration. -
FIG. 3 shows the container in its collapsed configuration. This is the typical configuration for storage or transportation of the container. Starting from this configuration, the user first unscrews thestorage chamber body 26 from the mixing chamber 4. This releases the air tight seal between thestorage chamber body 26 and the mixing chamber 4 and prevents the generation of a partial vacuum within the mixing chamber during expansion. The mixing chamber is then expanded by urging the twoend 6, 8 apart. Once expanded, the sealingfilm 34 is removed to expose the powdered concentrate product located within the storage chamber. Thestorage chamber body 26 is then screwed back onto the mixing chamber 4. Theclosure element 20 is then unscrewed from the top 6 of the mixing chamber 4 and a diluent (such as water) is added to the mixing chamber via the open end 6 of the mixing chamber 4. Theclosure element 20 is then screwed back onto the top end 6 of the mixing chamber 4 and the concentrated powdered product is mixed with the diluent, for example with agitation or shaking. The circular bellows arrangement aids with the mixing of the concentrated powdered product and the diluent. - The skilled person will appreciate that the concentrated product within the storage chamber defined by the
storage chamber body 26 may be in the form of a liquid, paste or gel, instead of a powder. -
