Description

BAG TO COLLECT HUMAN BODY WASTE AND DRENABLE ADAPTER FOR THE SAME Field of the Invention The present invention relates to the field of collection bags for human body waste, and in particular, to a drainable collection bag. The bag is intended to collect liquid. For example, the bag can be a urostomy bag or a urine collection bag The invention also relates to a drainable adapter for a bag.

Background of the Invention A common type of drainable urostomy bag comprises a valve arrangement or drainable tap at its lower end, through which the collected urine can be emptied. However, the key or valve arrangement represents a significant additional manufacturing and cost inconvenience, making the bag more expensive to produce. The components of the key or valve have to be molded separately from the bag, and then fastened to the bag. Frequently, a key comprises several components that can not be pre-assembled, requiring assembly to be completed after attachment to the bag. The integrity of the bag depends on the key arrangement or REF: 175014 valve, and often it is not possible to test the quality of a valve or valve before installation in the bag. U.S. Patent No. 6,419,664 discloses a drainable urostomy bag comprising an elongated discharge portion provided by an extension of the bag walls. The discharge portion can be folded in a closed condition that is said to seal the discharge portion. The discharge portion has a drainable, internal, relatively narrow passage, the width of which is less than 60% of the external width of the discharge portion. The drainable passage has a generally fluted shape tapering gently to a narrow portion within the discharge portion. When the discharge portion is folded to its closed condition, the drainable passage collapses to seal the discharge portion. However, the drainable passage is narrow and can stick in its collapsed state (called pancake type formation) when the discharge portion is deployed. U.S. Patent No. 6,419,664 teaches the permanent sealing of a tube in the discharge portion to expand the drainable passage when the discharge portion is deployed. However, this tube inevitably blocks the hermetic folding of the discharge portion when it is in its closed condition, possibly reducing the integrity of the seal and creating excessive watering when a compact folded shape would be more than desirable to the user. The publication U.S. No. 2004-0049837-A1 discloses a drainable, more refined urostomy bag, also comprising an elongate, foldable discharge portion formed as an extension of the bag walls. Deformable deflection strips provided at the distal portion of the discharging portion allow the user to manually control the degree of distension of the discharge outlets, thereby controlling the flow velocity of the liquid contents during emptying. The content of the publication U.S. No. 2004-0049837-Al is incorporated herein by reference.

BRIEF DESCRIPTION OF THE INVENTION Speaking lately, a first aspect of the invention provides a drainable bag for collecting human body waste, comprising first and second walls defining a collection region and a discharge portion depending on the region of collection, the discharge portion that is configured to be foldable to a closed position in which the discharge portion is sealed. The bag can be a collection bag liquids and / or an ostomy bag. The discharge portion includes a discharge passage defined only by portions of the first and second walls. The discharge portion may be absent, an additional tube member permanently sealed within the discharge portion. The first aspect further includes one or more of the following preferred features: (A) The bag further comprises a collapsible tongue to at least partially enclose the discharge portion when in the closed position. The tongue is permanently sealed to both the first and second walls by a seal extending through at least one of the first and second walls to the other. The seal is a step welding. The seal is near, or in, the discharge portion. The joining of a tongue using a seal simplifies fabrication as compared to joining a tongue to only one wall without also avoiding the other wall in the joining process. In addition, the seal provides an advantageous deflector effect within the bag. (B) The bag further comprises a deflector positioned adjacent to the discharge portion. The deflector is formed by a direct seal between the first and second walls of the bag. As explained above, the baffle can optionally be provided by a seal associated with a tongue. The deflector is configured as an islet that does not cross a side seal of the bag. There are gaps around either end of the deflector. The baffle is effective in controlling the watering of the bag when the bag is filled with liquid. Additionally or alternatively, the baffle is effective in controlling at least partially the rate of discharge of the liquid through the discharge portion when the bag is being dewatered. (C) The discharge portion comprises a drainable passage having a narrow or constricted region.

Optionally, at least a portion of the drainable passageway downstream of the narrow region has an internal width greater than the internal width in the narrow region. The discharge opening of the discharge portion has a wider width than the internal width in the narrow region. The narrow or constricted region functions to control the flow velocity of the liquid through the drainable passage when the bag is being drained. Additionally or alternatively, the narrow region functions as a stop for placing a portion of a drainable adapter that can be inserted into the opening of download. The stop helps in the easy placement of the drainable adapter inside the discharge portion, in a correct position to achieve a liquid tight seal. Additionally or alternatively, the narrow region functions as a region against which a drainable adapter that can be inserted into the discharge opening forms a seal, in use. (D) The bag further comprises a stepped region between a relatively wide collection region of the bag, and the discharge portion. The stepped region includes multiple stages of passage. The stepped region includes a first step that narrows the width of the bag to an intermediate width, and a second step that narrows the intermediate width to the width of the discharge portion. The steps in the width of the bag can be steps in the internal width and / or the external width. The stepped portion is highly effective in controlling the shape of the bag when it contains collected material. The stepped portion is especially advantageous in combination with a baffle at or near the stepped region. (E) The bag further comprises at least one deviation member located in the discharge portion. Additionally or alternatively, the bag further comprises a permanent islet seal between the first and second walls, the islet seal that does not cross a side seal of the bag. A second aspect of the. The invention generally provides a drainable adapter in isolation - or in combination with a drainable human body waste collection bag. The drainable adapter can be attached to the discharge portion of the bag to drain the contents to another location. The bag may include any of the features of the first aspect. The drainable adapter includes one or more of the following features: (A) The drainable adapter includes first and second portions for intersection in the bag discharge opening, the second portion being wider than the first portion. The second portion defines a shoulder with respect to the first portion The shoulder is configured to butt against a constriction within the discharge portion of the bag to assist in the proper placement of the adapter This is especially effective in allowing the The adapter is positioned optimally without the user needing to see inside the discharge portion, the first portion and / or the second portion having a shape that is generally oval, or in general in shape. of eye, or in general in the form of almond. This form achieves an optimum fit within the discharge portion, especially when the discharge passage is defined only by the first and second walls, and not by a permanently sealed additional tube member within the discharge portion of the bag. (B) The drainable adapter comprises a plug, an actuator, and a controller for the actuator. The actuator is configured to enlarge. and / or selectively reducing a size of a distal end of the plug. The controller is located at a proximal end of the plug, to allow easy operation by a user from outside the bag, even when the plug is inserted into the discharge opening. (C) The drainable adapter comprises a plug and a clamp. The plug can be inserted into the discharge portion of the bag. The clamp can be operated to hold the material of the discharge portion around the plug, to form a liquid-tight seal against the plug. Various forms of the clamp are contemplated. The clamp can be a separate member of the plug, or it can be attached to the plug. The plug may further comprise supports for supporting the ends of the clamp relative to the plug. In one form, the clamp opens by hinge around a hinge axis generally parallel to a plug axis. In another form, the clamp opens in a hinge around an axis generally perpendicular to a plug axis. The above aspects and / or features can be used independently of each other, or additional advantages can be obtained by using two or more in combination. The combination of drainable bag and drainable adapter can also be referred to as a drainable collection system. The additional features and advantages of the invention are described in the claims and in the following description. Protection is claimed for any new feature and / or combination of features described herein and / or illustrated in the figures, whether emphasis has been placed on them, or not.

Detailed Description of the Invention With reference to Figures 1-5, a bag 10 for collecting liquid human body waste is illustrated. The bag 10 can be, for example, a urostomy bag or a urine collection bag (for example for incontinent persons). The bag 10 generally comprises a front wall 12 and a rear wall 14 of flexible plastic film generally impermeable to liquid. The front wall 12 and the rear wall 14 are secured together around a peripheral seam 16. The seam 16 can be a seam 16 welded or heat sealed. A so-called comfort layer 18 of a relatively soft material is provided in the exterior of one, or both, of the front and rear walls 12 and 14. In the present embodiment, the comfort layer 18 is provided in at least the wall facing the body, for example, the rear wall 14. provides an entry opening 20 in an upper region of the bag 10. The illustrated embodiment is a "urostomy bag," and the entry opening (eg, a stomal opening) 20 is provided in the rear wall 14. connecting device 22 is provided around the entrance opening 20 for directly or indirectly attaching the bag 10 when used in the body., the joining device 22 comprises a plate or wafer of adhesive compatible with the skin for directly attaching the bag to the wearer's skin. Alternatively, the attachment device 22 comprises part of a detachable fastener for releasably attaching the bag 10 to a mounting wafer (not shown) used in the body. The fastener can be an adhesive-based fastener, or a mechanical coupling fastener. In an alternative form of the collection bag 10 (eg, for an incontinence collection bag), the entry opening comprises an inlet tube (shown in broken lines at 20 ') that enters an upper region of the bag. 10 instead of the stomal opening 20 in the rear wall 14.

The bag 10 includes an anti-spill or non-return valve 24 for obstructing the liquid collected within the bag 10 from splashing back into the inlet opening 20 (or 20 ') as the user moves around. The non-return valve 24 comprises one or more curtain sheets 26 joined together and / or to the front wall 12 and / or to the rear wall 14 in separate positions 28, to define a flapper valve. The present embodiment includes two curtain sheets 26 suspended between the front and rear walls 12 and 14, to define a hinged flapper valve (as shown in Figure 3). The lower region of the bag 10 generally comprises a discharge portion 30, and a stepped portion 32 at the proximal (or upper) end of the discharge portion 30. The discharge portion 30 and / or the stepped portion 32 are formed by extensions of the front and rear walls 12 and 14, to be integral with the rest of the bag 10. ' The stepped portion 32 generally comprises at least one reducing profile from a relatively wide portion 34 of the bag 10 (e.g., a main picking region of the bag), and a relatively narrow width of the discharge portion 30. In the illustrated embodiment, the stepped portion 32 includes several different stages of passage, for example, first and second 36a and 36b.

One or more of the passage stages may have a relatively steep passage shape (e.g., step 36a) and / or one or more of the passage stages may have a tapered shape in a relatively gradual manner (e.g. 36b). The multiple step stages of the stepped portion define a profile of multiple S (for example a double S profile in the illustrated mode). The stepped portion 32 may be symmetrical on the left and right sides of the bag 10, or may be asymmetric. The first step 36a reduces the width from a first width other than "a" to a second width "b". The second step stage 36b reduces the width from the second different width to a third different width "c". The term "distinct width" refers to a width that is relatively stable or identifiable as compared to an adjacent region in which the width can change significantly. The references herein to a "width" refer to the width when the bag is in a generally flat and / or empty condition. A baffle 38 is formed between the front and rear walls 12 and 14. The baffle 38 is formed in the stepped portion 32. In the present embodiment, the baffle 38 provides an islet seal directly between the front and rear walls 12 and 14. The islet seal can be a weld. The baffle 38 is provided by a Step welding joining a tongue 40 (described in more detail below). Alternatively, the baffle 38 comprises a wall or fold between the front and rear walls 12 and 14. The baffle 38 joins the front and rear walls 12 and 14. A free space exists on one or both sides of the baffle 38. deflector 38 is generally straight (as illustrated), or it may be curved. Deflector 38 is continuous (as illustrated), or may be discontinuous (eg, formed by separate baffle segments, such as spot welds). The baffle is formed to be generally aligned (e.g., in a vertical direction) with any of the steps 36a and 36b of the stepped portion, or with an intermediate position between the steps 36a and 36b. The lateral dimension of the baffle 38 is less than about 80% of the internal width of the bag 10 in the region around the baffle 38 (e.g., the width "b" in the illustrated embodiment.) The side dimension is less than about 70% or less than about 60%, for example, about 50%, of the internal width The lateral dimension is at least about 30%, or at least about 40% of the internal width The deflector 38 provides one or more of the following characteristics : (a) Deflector 38 helps control the watering of the bag 10 when the bag is full of collected liquid. The configuration of the stepped region 32 further aids in controlling the shape of the bag 10. In particular, the configuration of the stepped region 32 helps to avoid a tendency of the bag 10 to be folded around the baffle 38 when the bag 10 is full, which can otherwise completely constrain the clearances 42 and can make it difficult to drain. (b) The baffle 38 helps control the rate at which the liquid contents are relieved through the discharge portion 30, and in particular, prevents a sudden discharge when the discharge portion 30 is opened. (c) In the illustrated manner, the baffle 38 is formed by pass welding when the tongue 40 is attached to the bag. The formation of a pitch welding simplifies the manufacturing process by allowing a welding process comprising both of the walls of the bag. The formation of a pitch welding is simpler than welding the tongue 40 selectively to only one wall of the bag without comprising the other wall of the bag. The discharge portion 30 comprises sealed side edges 50 defining a passage 52 drainable therebetween. The drainable passage 52 communicates with a discharge opening 54 at the distal portion 30 of the discharge portion 30. The sealed side edges 50 are integral with and / or in continuation of the seam 16.

A lateral constriction 56 is formed in the drainable passage 52 upstream of the discharge opening 54. The construction 56 constricts the lateral width of the drainable passage 52. The constriction 56 controls the speed at which the liquid drains through the drainage passage 52 (as an alternative to, or in combination with, the baffle 38). The constriction 56 terminates before the discharge opening 54, such that a width "d" of the passage 52 drainable at the exit 54 is greater than a width "e" of the passage 52 drainable (for example, the minimum width) in the region of the constriction 56. The constriction 56 is defined by portions or extensions of the seam 16 at the side edges 50 of the discharge portion 30. The constriction 56 has a relatively gradual ramp profile 58 in its upward region, and a relatively abrupt profile 60 that faces the discharge aperture 54. The relatively soft ramp portion 58 provides a smooth flow of liquid during emptying of the bag. The relatively abrupt profile 60 provides an anti-drip feature. The constriction 56 (and in particular the lower profile 60) additionally or alternatively, provides a stop for accurately positioning a plug portion of a insertable adapter in the discharge portion (as described below). One or more biasing members 62 are provided in the discharge opening 54. The, or each, member of deviation may be plastic and may be capable of bending. In the present embodiment, two deviation members 62 are used, one in each of the "front and rear" walls 12 and 14. However, in an alternative embodiment, an individual deviation member may be used in only one wall. , "as desired. Each biasing member 62 functions to bias the shape of the discharge opening "54. Each biasing member 62 is" normally flat, or nearly flat, to bias the closed or nearly closed opening 54. The biasing members 62 are resiliently deformable in the application of finger pressure to the opposite ends of the biasing members 62 to distend the discharge opening 54. Alternatively, each deviation member 62 is formed to retain the opening 54 at least partially open in the relaxed state of the deviation member 62. The biasing members 62 are resiliently deformable to allow the opening 54 to close when flattening the biasing members 62, e.g., against each other if two biasing members 62 are used. Two deviation members 62 are offset laterally with respect to each other -other, what has been found that promotes the flexion of the diversion members 62 in opposite directions, as desired. The additional construction details of the diversion members 62 are found in U.S. No. 2004-0049837-Al mentioned above. The discharge portion 30 is "configured to be closed by winding or folding the discharge portion 30 one or more times, in a direction toward the main collection region of the bag 10 (as shown in Figures 5a and 5b). Deflection members 62 define a length of unitary crease around which the discharge portion 30 folds in. A discharge portion holder 64 is provided by engageable portions 64a and 64b of a mechanically coupled distributed fastener. 64a and 64b are located on the front and rear surfaces of the bag 10 at relative positions such that the parts 64a and 64b are in face-to-face alignment when the discharge portion 30 is folded to a fully closed position. it is provided as additional security to prevent accidental release of the discharge portion holder 64. As best seen in Figure 5b, the tab 40 is configured to be foldable around or under the folded discharge portion 30 as a protector. HE provides a fastener 66 of. tongue by engageable portions 66a and 66b of a distributed mechanical coupling fastener worn on the tongue 40 and an opposite surface of the bag 10, to secure the tongue 40 when being folded around the discharge portion 30 '. In the present embodiment, the tongue 40 is provided in the front wall 12 of the bag, and the part 66b of the tongue fastener is provided in the rear wall 14, although the relative positions can be inverted, as desired. The fasteners 64 and 66 of distributed mechanical coupling can be, for example, hook and handle material. However, it may be preferred to use instead a hook-hook (or "male-male") fastener. This fastener allows all the parts 64a, 64b, 66a and 66b of the fastener to be plastic extrusions, which can allow the person with an ostomy to wash and / or dry the fastener parts more easily. Additional details of the folding and opening of the discharge portion 30, the use of the tab 40 and the configuration of the fasteners 64 and 66 are found in U.S. No. 2004-0049837-Al mentioned above. It will be appreciated that the invention, particularly as illustrated in the preferred embodiment, allows a The liquid collection bag 10 is provided without any tube member permanently embedded in the discharge portion. The absence of a tube member allows the discharge portion 30 to fold tightly in its closed position to achieve both a hermetic seal and a compact shape that avoids undesirable, significant bulging. Figures 6-18 illustrate embodiments of the adapters 70a, 70b, 70c and 70d connectable to the discharge portion 30, to allow the contents of the bag to drain into a remote collector (not shown). These adapters 70 are useful for the continuous draining of the bag 10, for example, while the user is sleeping. The adapters 70 are configured in a special manner to form a reliable liquid-tight seal to the discharge portion 30 in the absence of a round tube embedded in the discharge portion 30. With reference to Figures 6-11, a first example adapter 70a is illustrated. The adapter 70a is intended for at least partial insertion into the outlet portion 30. The adapter 70a includes a self-anchoring configuration for internally anchoring the adapter with respect to the construction 56 of the discharge portion 30. The self-anchoring configuration comprises a device that can be inserted into or through constraint 56, and can be expanded in or behind the constriction 56 to fix the device within, or from one or both sides of, the constriction 56. The adapter 70a generally comprises a central tube 72, an enlarging actuator 74, and a cover 76 expandable. The central tube 72 is hollow and opens at the opposite ends 78a and 78b for the flow of fluid through the central tube 72. The expandable cover 76 is integrally formed (for example it is molded integrally) with the central tube. 72, or joins it, to define a unitary article. The expandable cover 76 is sealed to the central tube 72 at the distal end 78a, and defines an annular free space 80 (eg, an annular cavity) that is open from below, between the outer cover 76 and the central tube 72. The actuator 74 of enlargement is carried in the central tube, and extends in the annular free space 80. The enlarging actuator 74 extends tongues 82 which are arranged to be urged outwardly by actuating cams (not shown) in the relative displacement between the actuator 74 of enlargement and the central tube 72. The displacement is axial displacement and / or rotary movement, as desired. When displaced outwardly, the tongues 82 impart an enlarged bulging head to the expandable cover 76, as depicted in dashed lines in FIG. 84 in Figures 8 and 11. The exact shape of the bulging end 84 varies. depending on the configuration of the outer cover 76, and the material from which the outer cover 76 is made. The outer cover 76 may be of any suitable material, for example, an elastomer. The lower end of the enlarging actuator 74 opposite the tongues 82 is formed with a finger-engagable surface 86, for example, a strip surface. The enlarging actuator 74 is held captive in the central tube 72 by a counter-grip 88 and / or a retaining ring 90. The counter-grip 88 has a finger-engaging surface similar to the enlarging actuator 74. The retaining ring 90 can be secured to the central tube 72 by a bayonet-type coupling between bolts 92 in the central tube 72 and receiving depressions 94 in the retaining ring 90. The reception depressions 94 include cantilever clips 96 to trap the pins 92 in a condition fully engaged in the depressions 94 (as best seen in Figures 7 and 9). Additionally, if the retaining ring 90 is omitted, the counter-grip 88 can be attached directly to the central tube 72. The outer cover 76 is profiled with a shoulder 98 sized to fit within the opening 54 of discharge from the bag 10. With reference to Figure 11, the shoulder 98 is dimensioned to be stopped by the constriction 56. In use, a user attaches the adapter 70a by inserting the adapter 70a into the discharge opening 54 until the shoulder 98 abuts the lower profile 60 of the constriction 56. Thereafter, the user grasps the finger-clamping surfaces of the enlarging actuator 74 and the counter-grip 88 to manipulate the enlarging actuator 74 to expand the end 78a. of the outer cover. The expanded end 84 firmly fixes the adapter 70a with respect to the constriction 56 of the discharge portion 30. The expanded end 84 also provides a liquid tight seal between the adapter 70a and the discharge portion 30 to prevent liquid from leaking between the wall material of the bag and the adapter 70a. The shoulder 98 allows a user to insert reliably and place the adapter 70a in the correct position within the discharge portion 30 of the bag. The user can perceive when the adapter 70a is correctly positioned in abutment to the constriction 56, even if the user is not able to see inside the bag. In addition, the shoulder 98 ensures that the adapter 70a is positioned correctly such that, when the end 78a is enlarged (at 84), the enlargement in the correct position in relation to the constriction 56 it forms a hermetic seal to liquids. The placement of the finger-gripable surfaces of the enlarging actuator 74 and the counter-barge 88 below the shoulder 98 ensures that these parts are easily accessible to the user, even when the adapter is inserted into the discharge opening 54 of the bag 10. Figures 12 to 14 illustrate a second embodiment of the adapter 70b. The adapter 70b comprises two separable or separate parts, which include a plug 100 and a clamp 102. In Figure 13, the plug 100 and the clamp 102 are sampled together, to illustrate their mutually formed positions. The plug 100 is formed similarly to the central tube 72 and the cover 76 of the adapter 70a described above. The plug includes a central tube 104, and an outer cover 106, integrally molded. The outer cover 106 includes a sealing channel 108. The sealing channel is lined with a channel pack 110, for example, of an elastomeric material. The package can be integrally molded with the outer cover 106, or it can be fitted as a separate article, the outer cover can also include a positioning shoulder 111, similar to the shoulder 98 of the adapter 70a. The clamp 102 comprises a first and a second limbs 112 joined at one end by a chamele 114, for example, an integrally molded animated hinge. Each end 112 includes a cut or depression 116 to fit around the outer cover 100. Each end 112 carries an end pack 118, for example, of elastomeric material, to seal against the surface of the bag. The package 118 can be integrally molded with each end 112, or it can be a separate article attached to the end 112. Each end 112 and / or its packing 118 includes one or more sealing protruding ribs 120. The ribs 120 include a central rib 120b sized to fit within the channel 108 of the plug 100 when the clamp 102 fits around the plug. The ribs 120 may include one or more peripheral ribs 120a and 120c for additional local sealing. The central rib 120b may be part of the peripheral ribs 120a and 120c The ends 112 further comprise a clasp 122 formed by interlockable formations at the ends of the ends 112 opposite the hinge 114. The clasp 122 releasably secures the ends 112 together in a holding position. In use, the user first inserts the plug 100 into the discharge outlet 54 of the bag, until the Placement shoulder 111 joins butt to constriction 56 in the discharge portion 30 of the bag. Subsequently, the user places the clamp 102 on the outside of the discharge portion 30, such that one of the limbs 112 is in a predetermined position. For example, the predetermined position may be between two of the mechanically coupled distributed fastener portions 64a and 66b on the rear surface 14 of the bag 10. The ends 112 are sized to fit in a relatively comfortable manner between the parts 64a and 66b of bra to make placement easy. The ends 112 of the clamp 102 then close together around the outside of the discharge portion 30 to hold the discharge portion 30 against the plug 100, and thereby form a secure liquid-tight seal. The limbs 112 are locked by the clasp 122. In a manner similar to the adapter 70a, the shoulder 111 of the plug 100 allows the plug 100 to be properly positioned within the discharge opening 54 of the bag 10 for coupling by the clamp 102. The user can perceive when the plug 100 has been completely inserted by the shoulder 111 that abuts the constriction 56 within the discharge portion 30, thus avoiding any need for the user to be able to see inside the the discharge portion. The Bra portions 64a and 66b provide highly effective tactile and visual guides for positioning the bracket 102 in the correct position on the outside of the bag 10, allowing the adapter 70b to be easily and quickly adjusted by almost anyone with an ostomy. The sealing packs 110 and 118 allow a relatively high sealing force to be applied without significant risk of damage to the bag wall material. The positive coupling between the sealing channel 108 and the rib ~ 120b provides a highly effective liquid tight seal. The plug 100 and the clamp 102 have a generally oval or eye (or almond) shape, to correspond to the natural opening shape of the discharge portion, in order to achieve an optimal liquid-tight seal. Figures 15 and 16 illustrate a third exemplary adapter 70c. The third adapter 70c is very similar to the second adapter 70b described above, and the same reference numbers are used where appropriate to denote features already described. The third adapter 70c unifies the plug 100 and the clamp portions of the second adapter 70c in a unitary member 130. The member 130 includes support 132 extending laterally from the plug 100 for transporting the Clamps 112 of the clamp. Each support is substantially L-shaped, although other shapes may be used as desired. Each end 112 is hinged to the respective support 132, for example by an animated hinge. - Compared to the second adapter 70b, the third adapter 70c is a one-piece article (or a assembly of permanently connected parts). The use of an article or assembly of a piece reduces the risk that the user accidentally releases either the plug or the clamp if these items have to be stored as separate items when they are not in use. The brackets 132 also ensure that the limbs 112 of the bracket are always correctly aligned with respect to the plug 100, thus further relieving a user load to correctly position the bracket in use (or the exterior of the bag) with respect to the plug (or the inside of the bag). Figure 17 and 18 illustrate a fourth example of adapter 70d. The fourth adapter 70d is similar to the third adapter 70c described above, and the same reference numbers are used where it is appropriate to indicate characteristics already described. In the fourth adapter 70d, the clamping fingers 112 are hinged to the plug 100 to open and close like a clam shell.

Each limb 112 comprises a profiled plate or shell having a seal package 118. The limbs 112 can be secured together by means of movable tongues or fins 140. The tabs 140 are hinged to any of the limbs 112 to move generally in the same plane as the limb. As dashed lines are indicated at 142 in Figure 18, one or both of the shells includes a gap or window, to reduce an amount of plastic material, and thereby reduce the manufacturing cost. The gap allows the user to at least partially see the discharge portion 30 of the bag 10 even when the adapter 70d has been adapted. It will be appreciated that the adapters 70a-d are configured to interact with the constriction 56 of the discharge portion 30, to facilitate easy insertion of a portion of the adapter in the correct sealing position, without requiring the user to be able to see inside. of the discharge potion. The above description is only illustrative of the preferred embodiments of the invention. Many improvements, modifications and equivalents may be used within the scope and / or spirit of the invention. It is noted that in relation to this date, the best method known by the applicant to carry out the present invention is that which is clear from the present description of the invention.
