The invention relates generally to containers for retaining fluids and has particular applications in the field of medically related containers for temporarily retaining urine and other bodily fluids. The invention further relates to a method of manufacture of a container.
The closest prior art known to the Applicant is a temporary container for retaining body fluids, such as urine, in a hospital or surgery setting. Temporary containers are typically required for patients who are not able to get out of their hospital bed to go to the toilet. The container allows them to relieve themselves and the urine can then be taken to a toilet for flushing or to another specialised facility for disposal by a nurse or other suitably trained person.
Typically, patients are provided with a bed pan or a pot made of rigid recyclable material, such as moulded pulp, which is sufficiently waterproof to retain liquid for at least enough time to take it to a toilet. An example of this is the device marketed by Vernacare™ under the trade name VernaFem.
However, the use of current containers suffers from a number of disadvantages, particularly for female patients. Firstly, with current bed pan or pot configurations, a patient must often get themselves into an unnatural position to urinate accurately into the container without spilling any fluid onto bed sheets, something which causes self-evident problems if not dealt with and something which medical staff often do not have the time to deal with swiftly. Moreover for many patients, such movement is not easily accomplished. Second, existing containers comprise material which is set into the bed pan or pot shape to provide rigidity, or from which the material is made. These function to a point for the patient, if they have managed to get themselves into the required, unnatural position but their configuration increases the space required to transport and store the containers prior to use. This is a particularly important issue given the number of different supplies that must be stored and ready for use within a hospital and can increase the costs of running a hospital. Additionally, many containers are only able to provide a volume for the liquid which is often too small for what the user can produce, a problem exacerbated if the container is used in a sub-optimal orientation.
A potential solution to these problems would be to insert a catheter into each patient to facilitate the passing of urine into a bag or other container. However, this causes obvious discomfort to a patient which would be unwelcome following any major or minor surgery. The carrying out of a further procedure also carries with it the increased risk of infection or complications and must therefore be avoided wherever possible.
It is therefore an object of the invention to alleviate these problems and provide a method of producing a container which reduces transportation costs and improves the storage capacity of a hospital or surgery, whilst providing a container which is intuitive for a patient to use and allows them to rest in a more natural position during use. It is a further object of the invention to provide a container which addresses the above problems.
In a first broad independent aspect, the invention provides a method of producing a container for retaining fluid, the method comprising the steps of:
This method is particularly advantageous because it provides steps for swiftly assembling a container from a blank. Forming a container from a blank reduces the transportation costs of the containers as more blanks can be transported in the same space as with existing containers. An increased number of blanks can also be stored at a hospital or surgery prior to use because of their flat, pre-formed configuration. The step of deforming one or more deformable portions provides a patient (or other person) with an intuitive way to assemble the container. This is especially important because a container must be fast and straightforward to assemble in case of urgent requirement.
In a subsidiary aspect, the step of folding the blank along one or more fold lines across the blank's width forms a rectangular side wall. This configuration is particularly advantageous because it provides a method for producing a more intuitive container for a user to open up from a folded, flat configuration to an, in use, open configuration.
In a subsidiary aspect, the step of folding the blank along one or more fold lines across the blank's width forms a trapezoidal side wall.
In a subsidiary aspect, at least one edge of the side wall is curved.
In a subsidiary aspect, wherein the step of sealing the first and second ends of the side wall to one another comprises the use of an adhesive.
Preferably the method further comprises the further step of sealing a lid at least partially around the circumference of a second edge of the side wall, such that fluid can enter and be stored within the cavity formed by the assembled blank. By sealing a lid at least partially around the circumference of a second edge of the side wall the entry and exit of fluid from the container can be controlled and the risk of spillage from the container can be minimised.
Preferably, the lid is sealed partially around the circumference of the second edge of the side wall, such that an aperture is formed where the lid is not sealed to the second edge. Partially sealing the lid around the circumference of the second edge of the side wall provides an aperture for fluid to enter and exit the cavity. The partial sealing also provides a space for absorbent material to be placed in the aperture to increase comfort to a user and prevent or minimise spillage of fluid from the container.
Preferably, the lid has an opening and is sealed around the entire circumference of the second edge of the side wall. Control of fluid flow into and out of the container is thereby further improved.
Preferably the steps of sealing the first and second ends of the side wall to one another and sealing the base and lid to first and second edges of the side wall comprise the use of an adhesive. The use of an adhesive improves the fluid retaining capability of the container. The use of an adhesive also minimises the risk of the container breaking once it has been formed from its blank.
Preferably, the method further comprises the further step of providing a label on an outer surface of the blank. Providing a label on the outer surface of the blank allows the container to be identified as containing a fluid which might be considered as a biohazard. This reduces the risk of the container being mistaken for another.
Preferably, the method further comprises the step of providing a passage between the cavity of the assembled container and the label. Providing a passage between the cavity of the assembled container and the label allows improves the identification of the container's contents. For example, if a label which was reactive to blood types was applied to the outer surface of the container, the label would indicate which blood type was contained without the need for further testing.
Preferably, the first and second edges of the side wall are substantially opposite from one another. This is particularly advantageous because it means that the base and lid are on substantially opposite sides of the container, which reduces the risk of spillage from the container.
In a second broad independent aspect, the invention provides a pre-container, expandable from a flat, folded configuration to an, in use, container for fluids, the pre-container comprising a first portion comprising a first side wall having at least two ends and two edges and an additional side wall, the additional side wall having at least two additional side walls ends and two additional side wall edges and hingedly attached along one of the edges to an edge of the first side wall, and sealingly secured along the second edge to the second edge of the first side wall to form a continuous ring; the pre-container comprising a base portion which is sealingly fixed to an end of each side wall; and wherein the pre-container further comprises a number of deformable regions which span across adjacent wall and side walls, such that when pressure is applied to the deformable regions the pre-container is formable into a container.
This configuration is particularly advantageous because it provides a pre-container which can be intuitively squeezed to open up a cavity between the two or more side walls to form a container. This allows the pre-container to be stored as a relatively flat body but opened up into a container when required, in a straightforward manner, to provide a cavity for retaining fluid.
Preferably, the pre-container comprises more than one additional side wall, the or each additional side wall being joined along one edge to an additional side wall or the first side wall, such that each side wall is attached to, at most, two other side walls, and where at least two adjacent side walls of the pre-container being non-hingedly secured together.
This configuration is particularly advantageous because it provides a pre-container which is straightforwardly formable into a container.
Preferably, the second edge of the or each additional side wall is secured to the second edge of the first side wall by an adhesive. An adhesive improves the sealant properties of the pre-container.
Preferably, the base portion is fixed to an end of the or each side wall by an adhesive. This further improves the sealant properties of the pre-container, and the risk of the base becoming detached from the remainder of the formed container in use is minimised.
In a third broad independent aspect, the invention provides a blank for a container for retaining fluid, the blank comprising a first portion comprising a first side wall having at least two ends and two edges and at least one additional side wall extending from an edge of the first side wall, each additional side wall having at least two additional side wall ends and two additional side wall edges; the blank comprising a second portion comprising a base which is fixable to an end of the or each side wall; wherein the joins between the side walls comprise a hinged folds; and wherein the blank further comprises a number of deformable regions which span at least partially across the joins between each side wall, the blank being able to form an assembled container when the edges of side walls which are not joined to another side wall edge are brought into close proximity with one another, the base is fixed to a short side of each side wall, and the deformable regions are disposed inwardly, such that a cavity is formed within the assembled container.
This configuration is particularly advantageous because it provides a blank which facilitates the swift assembly of a container from the blank. Forming a container from a blank reduces the transportation costs of the containers as more blanks can be transported in the same space that existing containers are transported in. An increased number of blanks can also be stored at a hospital or surgery prior to use because of their flat, pre-formed configuration. Even when formed, the container can also be kept in a ‘flat’ configuration where the deformable regions are not disposed inwardly, which further minimises the space occupied by a container. The deformable regions provide a patient (or other person) with an intuitive way to assemble the container as, when the deformable regions are disposed inwardly, the remaining regions of the side walls are forced outwards to create a cavity. The fixable base improves the intuitiveness of the blank. This configuration provides a blank for a container which can be quickly and straightforwardly assembled in case of urgent requirement.
In a fourth broad independent aspect, the invention provides a blank for a container for retaining fluid, the blank comprising a first side wall having at least two ends and two edges and at least one additional side wall extending from an edge of the first side wall, each additional side wall having at least two additional side wall ends and two additional side wall edges; and a base which extends from an end of one of said side walls; wherein the joins between each of the side walls and base comprise a hinged fold; and wherein the blank further comprises a number of deformable regions which span at least partially across the joins between each side wall, the blank being able to form an assembled container when the edges of side walls which are not joined to another side wall edge are brought into close proximity with one another, when the base is folded and brought into close proximity with each side wall, and the deformable regions are disposed inwardly, such that a cavity is formed within the assembled container.
This configuration is particularly advantageous because it provides a blank which facilitates the swift assembly of a container from the blank. Forming a container from a blank reduces the transportation costs of the containers as more blanks can be transported in the same space that existing containers are transported in. An increased number of blanks can also be stored at a hospital or surgery prior to use because of their flat, pre-formed configuration. Even when formed, the container can also be kept in a ‘flat’ configuration where the deformable regions are not disposed inwardly, which further minimises the space occupied by a container. The deformable regions provides a patient (or other person) with an intuitive way to assemble the container as, when the deformable regions are disposed inwardly, the remaining regions of the side walls are forced outwards to create a cavity. The provision of the base which is integral with a side wall minimises the number of components required to assemble a container. This configuration provides a blank for a container which can be quickly and straightforwardly assembled in case of urgent requirement.
Preferably, said blank further comprises a lid which extends from an end of one of said side walls. The lid improves the control of entry and exit of fluid from the container. Moreover, by being integrally formed with the blank the intuitiveness with which a container is assembled is improved. Thus, the speed and efficiency with which the container can be assembled is also increased.
Preferably, when the blank is assembled, the lid and base are positioned at opposite ends of the first side wall. This configuration reduces the risk of spillage from the container.
Preferably, the side walls are substantially rectangular in shape. The rectangular shape provides an intuitive blank for a user to assemble. It will be made more apparent to a user from substantially straight edges of the rectangular side wall that the edges are to be fixed to one another.
In a subsidiary aspect, the side walls are substantially trapezoidal.
Preferably, the blank is able to form an assembled container which has a substantially hourglass shape. An hourglass shape provides the assembled container with stability. It also provides a region, i.e. a middle portion of the assembled container, which is easily gripped by a user during use.
In another broad aspect, the invention provides a container formed from a blank in accordance with any one of the preceding aspects. This provides a container which is intuitive to assemble so that large quantities of containers can be assembled efficiently.
Preferably, the container further comprises a portion of absorbent material which is placed at least partially an opening of the lid. The portion of absorbent material minimises the risk of spillage from the container during use, which improves the comfort to a user and hygiene of the container.
In a fifth broad independent aspect, the invention provides a container for retaining fluid, the container comprising two or more side walls, each side wall having at least two ends and two edges, the side walls being joined to one another along each of their edges to form a continuous ring; the container further comprising a base which is fixed to an end of each side wall around the circumference of the continuous ring; and whereby an opening is located between the ends of each side wall not fixed to the base; wherein the container further comprises a number of deformable regions which span at least partially across the joins between the edges of each side wall; wherein the deformable regions are configured to be pushed inwardly towards the centre of the formed passage in order to form a cavity.
This configuration is particularly advantageous because it provides a container which can be intuitively squeezed to open up a cavity between the two or more side walls. This allows the container to be stored as a relatively flat body but opened up when required, in a straightforward manner, to provide a cavity for retaining fluid.
Preferably, the container further comprises a lid which is fixed at least partially to an end of each side wall not fixed to the base. The provision of a lid improves the control of fluid into and out of the container, i.e. the lid can be opened prior to use and closed once fluid has been dispensed into the container to prevent or minimise spillage.
Preferably, the lid is only partially fixed around the circumference of the continuous ring at an end of the container not fixed to the base, such than an opening is retained where the lid is not fixed. This configuration is particularly advantageous because it minimises the risk of spillage from the container whilst providing sufficient space for a user to dispense fluid into the cavity.
Preferably, the lid comprises an absorbent material, such as gauze. This further minimises the risk of spillage from the container and improves the comfort to a user.
Preferably, the container further comprises one or more stands which are located at least partially along the joins between each side wall. The stands improve the stability of the container when it is placed upright on a surface and also provide a region which a user can hold the container in use.
Preferably, a stand is located along a portion of each join between side walls adjacent the base end of the container, and an additional stand is located along a portion of a join between side walls adjacent the lid end of the container. The stands located adjacent the base improve the stability of the container on a surface whilst the stand adjacent the lid can provide a point from which a user can hold the container so that the container isn't squeezed—which could potentially push fluid from the container—when carrying fluid to a toilet.
Preferably, the container further comprises a bottle top which is positioned in said opening between the short sides of each side wall not fixed to the base. The bottle top improves the control of fluid into and out of the container.
In the drawings:
The illustrated embodiments of the invention are currently the best ways known to the Applicant of realising the invention. But they are not the only ones: the skilled addressee of this specification may well be able to devise others without the need for inventive thought within the Summary of the Invention outlined above.
The blank 10 further comprises a second portion 27 comprising a base 28. The base 28 is fixable to a short end 14, 20, 22 of each side wall, 12, 17 and 18. The blank 10 further comprises a number of deformable regions, such as 29 and 30. Preferably the deformable regions 29 and 30 span at least partially across the hinged folds 15/24 and 16/25 between each side wall, 12, 17 and 18.
In use, the blank 10 is able to be formed into an assembled container (see
The base 28 preferably comprises a number of fold lines, such as 31 and 32, so that a lip of the base 28, such as 33, can be folded and fixed to a surface of each side wall 12, 17 and 18.
In a preferred embodiment, shown by
A number of further fold lines are provided, such as fold line 36, to create a number of stands adjacent the base and lid of the container. The stands improve the stability of the container once it is formed, and provide a point from which a user can hold the container during use.
In a preferred embodiment long sides 23 and 26 of side walls 17 and 18 are joined together with the use of an adhesive. The base 28 is also preferably fixed to side walls 12, 17, 18 with an adhesive.
The invention may be used for any type of container, including bottles, bowls, measuring jugs. It is envisaged that the invention has particular application as urinals for both males and females, particularly in a hospital setting.
The blank preferably comprises paperboard, carton board or Bagasse. The blanks can be internally or externally sized to provide the correct level of fluid resistance.
When the blank is formed, it can be switched from a ‘flat’ to an ‘open’ configuration by either pressing the deformable regions 129 inwards (to force the remaining regions of the side walls 112 outwards) to ‘open’ the container, or by pressing down on the side walls 112 such that the deformable regions 129 are forced outwardly and the container 100 is forced flat.
Prior to use, the container 100 may be in its unassembled, blank configuration or may be assembled but in a ‘flat’ configuration where the deformable regions, such as 129, have not been disposed inwardly. Either of these configurations allows the blank/container to be transported and stored in a minimal amount of space, thereby allowing a large quantity of blanks/containers to be transported and stored at the same time. When the container 100 is required, the deformable regions 129 are disposed inwardly to force outwards the remaining regions of the side walls, such as 112, to form a cavity within the container 100.
In a preferred embodiment, a lid 150 is provided which is fixed at least partially to a short end 113 of each side wall 112 opposite the end to which the base 128 is fixed. Even more preferably, the lid 150 is only partially fixed around the circumference of the passage formed by the side walls 112 such than an opening 139 is retained where the lid is not fixed. The lid 150 is preferably configured to receive a piece of absorbent material 140. The absorbent material preferably comprises gauze which is readily available in a hospital. The absorbent material 140 may be pre-formed to fit accurately on top of the lid 150, or a standard piece of gauze can be cut and/or folded and placed against the lid 150.
The container preferably further comprises a number of stands, such as 141, 142 and 143. The stands 141, 142143 are located at least partially along the joins between each side wall 112. Even more preferably, stands 142, 143 are located along a portion of each join between side walls 112 adjacent the base end of the container 100 and a stand 141 is located along a portion of a join between side walls 112 adjacent the lid end of the container 100. The stands 141, 142, 143 provide the container 100 with improved stability when it is placed on a surface. They also provide a user with points from which to hold the container 100 during and after use. This may be particularly useful once the container 100 has been filled so that the container 100 is not gripped around its mid portion, which might force the contained fluid from the container 100.
In a further preferred embodiment, the container 100 is an hourglass shape. This shape provides the container 100 with increased stability when it is placed on a surface, particularly in conjunction with stands 142 and 143. It also provides a user with an intuitive region in which to hold the container 100 during use.
In this embodiment, the base 1328 of the blank 1300 comprises three fold lines which extend across the width of the blank, thereby allowing the base 1328 to fold when the blank 1300 is assembled into a pre-container and stored in a flat configuration. The folding of the base, inwards towards the volume created by the blank 1300 reduces the size of the blank 1300 when it is stored pre-assembly.
In use, when the blank 1300 is assembled into a container, the fold which runs along the centre of the base allows the base to take a flat configuration to provide a container with improved stability. In a preferred embodiment, the base has a substantially rectangular shape to further improve stability.
Due to the shape of the blank 1300, the container which is assembled from the blank is tapered from the base 1328 inwards towards the short ends 1313, 1314 of the two side walls.
The blank further comprises one or more openings, such as 1340, to allow a user to fill the volume of the blank in use. In one embodiment, the blank comprises two openings, at different positions on the blank, for use by a male or female. The opening configured for use by a male is preferably positioned at a greater height than the opening configured for use by a female, due to the typically larger bladders of males. In this embodiment, the opening designed for a male may be smaller and the opening designed for a female may be larger to accommodate the increased difficulty for women to use a urinal.
In the embodiment of
In an alternative embodiment, a single opening is provided for use by males and females. In this embodiment, the height of the opening is preferably approximately 60 mm from the base of the assembled container and has a width between 80 and 95 mm when the container is in its assembled form.
The or each opening may be closed when the blank is in the blank or pre-container forms, and open when assembled into the container. In either embodiment, the openings may initially be provided with a covering which is integrally formed with the rest of the blank 1300 and which has a perforated border. A user may thus push either or both of the perforated coverings into the container prior to use.
In one embodiment, the or each opening comprises a tongue which is preferably folded down prior to use. The tongue provides at least part of the perimeter of the or each opening with a soft edge to minimise the risk of discomfort or injury during use.
The blank also further comprises one or more additional holes 1320 which are located towards one of the short edges of a side wall. The additional holes provide a means for the container to be carried and held in use. The tapered configuration of the assembled container allows the container to be straightforwardly and intuitively pinched and held.
In one embodiment, the blank of
The pre-container and assembled container of the blank of
This embodiment, or any other embodiment may share any number of the features of the alternative embodiments described.
Each of the blanks may be formed of a waterproof card, pulp, Bagasse, or a mixture thereof, and preferably the blanks are formed of a single piece of material.
