Definitions
- the invention relates to a connecting piece for use in a container for connecting it to a filling nipple of a dispenser, comprising:
- the closing element cannot be moved in axial direction when the connecting piece is mounted and can only be rotated about the longitudinal axis between an open and a closed position.
- the closing element protrudes partly from the housing and dirt or liquid can end up between the closing element and the housing.
- An object of the invention is to provide a connecting piece for a container, which can be opened and closed by cooperation with a filling nipple intended for this purpose, wherein the connecting piece closes more tight than the known connecting piece for long-term storage of the container.
- the connecting piece according to the invention is characterized in that the closing element, in the assembled state of the connecting piece, is slidable in the axial direction in the recess, between a first position in which the closing element is located at the location of a closed part of the wall of the housing, and a second position in which the closing element is located at a part of the wall in which the opening is present.
- the closing element is preferably slightly clamping in the recess in order to obtain a good seal in the first position. Because it is not necessary to turn the closing element in the first position, it can be clamped tighter in the first position in the inside of the recess and therefore seal better. This first position is especially favorable if a filled container provided with the connecting piece is stored for a longer period.
- the closing element in the assembled state of the connecting piece, is completely or almost completely present in the housing both in the first position and in the second position. This means that no dirt can get between the housing and the closing element when the connecting piece is closed by a cap.
- An embodiment of the connecting piece according to the invention is characterized in that one side of the circumferential edge of the flange is provided with a protruding lip and/or a recess for cooperation with a congruent shape of a wall of a recessed part of the dispenser around the filling nipple.
- the specifically shaped flange serves as a key and can be made in different shapes, each of which is a unique key for different types of containers.
- the connecting piece preferably comprises a cap for closing the recess, which cap is connected to the flange via a flexible hinge. To ensure that this cap does not form an obstruction when connecting a container to a filling mouth, the cap is preferably present on the circumferential edge of the flange opposite the protruding lip and/or recess.
- the invention also relates to a container provided with the connecting piece described above.
- This container is preferably formed by a plastic bag.
- the invention furthermore relates to an assembly of a dispenser provided with a filling nipple and a container provided with the connecting piece described above, which can be connected to the filling nipple.
- An embodiment of the assembly is characterized in that the closing element and the filling nipple are provided with mutually cooperating parts which are configured such that the closing element can be blocked against rotation by the filling nipple when the housing of the connecting piece is rotated. As a result, the closing element can be opened and closed by rotating the container relative to the filling nipple.
- the through opening in the wall of the closing element is preferably formed by a slot extending from the open end of the closing element in a direction to the opposite end, wherein the filling nipple fits into the further recess of the closing element and being provided with a projection that fits into the slot in the closing element. This allows the closing element to be blocked against rotation by the filling nipple when the housing of the connecting piece is rotated.
- a further embodiment of the assembly is characterized in that the dispenser is provided with a recess with a limiting edge, wherein this limiting edge and the circumferential edge of the flange of the connecting piece are formed in such a way that the connecting piece can only be fitted in one position sufficiently far over the filling nipple to couple the filling nipple to the closing element to block it against rotation.
- the closing element can only be turned if the connecting piece has been pushed sufficiently (completely) over the filling nipple so that the filling nipple is coupled to the closing element and blocks the latter against rotation.
- the connecting piece can only be slid sufficiently (completely) over the filling nipple in a certain position and also can only be removed from the filling nipple in this position. In this position the closing element is in the closed position so that the container can only be removed from the filling nipple in the closed position.

Abstract
Description
- The invention relates to a connecting piece for use in a container for connecting it to a filling nipple of a dispenser, comprising:
- a housing equipped with:
- a recess which is open at a first end and at an opposite second end, as well as
- a protruding flange at or near the first end of the recess, for coupling to the filling nipple, and
- a through opening in a wall of the housing,
- as well as a closing element present in the recess in the housing, which closing element is provided with:
- a further recess which is also open at a first end of the closing element, a second end of the closing element opposite the first end being closer to the second end of the housing than the first end of the closing element, as well as
- a through opening in a wall of the closing element,
- In the closed position of the closing element, if there is any excess pressure in the container, only a force/pressure in radial direction is exerted on the closing element. By locking the closing element radially in the recess, the force/pressure is absorbed by the walls of the closing element and the housing. This means that no such force/pressure is exerted on the closing element that can move/rotate the closing element and thus open the connecting piece.
- A connecting piece according to the preamble of
claim 1, which can be connected to a filling nipple, is known fromUS 5 425 479 A . In this known connecting piece, the closing element cannot be moved in axial direction when the connecting piece is mounted and can only be rotated about the longitudinal axis between an open and a closed position. In the known connecting piece, the closing element protrudes partly from the housing and dirt or liquid can end up between the closing element and the housing. - An object of the invention is to provide a connecting piece for a container, which can be opened and closed by cooperation with a filling nipple intended for this purpose, wherein the connecting piece closes more tight than the known connecting piece for long-term storage of the container. To this end, the connecting piece according to the invention is characterized in that the closing element, in the assembled state of the connecting piece, is slidable in the axial direction in the recess, between a first position in which the closing element is located at the location of a closed part of the wall of the housing, and a second position in which the closing element is located at a part of the wall in which the opening is present.
- The closing element is preferably slightly clamping in the recess in order to obtain a good seal in the first position. Because it is not necessary to turn the closing element in the first position, it can be clamped tighter in the first position in the inside of the recess and therefore seal better. This first position is especially favorable if a filled container provided with the connecting piece is stored for a longer period.
- Preferably, the closing element, in the assembled state of the connecting piece, is completely or almost completely present in the housing both in the first position and in the second position. This means that no dirt can get between the housing and the closing element when the connecting piece is closed by a cap.
- An embodiment of the connecting piece according to the invention is characterized in that one side of the circumferential edge of the flange is provided with a protruding lip and/or a recess for cooperation with a congruent shape of a wall of a recessed part of the dispenser around the filling nipple. In this way it can be achieved that only containers which are provided with a connecting piece with a specifically shaped flange can be connected to a filling mouth intended for this purpose and other containers which are not intended for this purpose cannot be filled with this filling mouth. The specifically shaped flange serves as a key and can be made in different shapes, each of which is a unique key for different types of containers.
- The connecting piece preferably comprises a cap for closing the recess, which cap is connected to the flange via a flexible hinge. To ensure that this cap does not form an obstruction when connecting a container to a filling mouth, the cap is preferably present on the circumferential edge of the flange opposite the protruding lip and/or recess.
- The invention also relates to a container provided with the connecting piece described above. This container is preferably formed by a plastic bag.
- The invention furthermore relates to an assembly of a dispenser provided with a filling nipple and a container provided with the connecting piece described above, which can be connected to the filling nipple.
- An embodiment of the assembly is characterized in that the closing element and the filling nipple are provided with mutually cooperating parts which are configured such that the closing element can be blocked against rotation by the filling nipple when the housing of the connecting piece is rotated. As a result, the closing element can be opened and closed by rotating the container relative to the filling nipple.
- The through opening in the wall of the closing element is preferably formed by a slot extending from the open end of the closing element in a direction to the opposite end, wherein the filling nipple fits into the further recess of the closing element and being provided with a projection that fits into the slot in the closing element. This allows the closing element to be blocked against rotation by the filling nipple when the housing of the connecting piece is rotated.
- A further embodiment of the assembly is characterized in that the dispenser is provided with a recess with a limiting edge, wherein this limiting edge and the circumferential edge of the flange of the connecting piece are formed in such a way that the connecting piece can only be fitted in one position sufficiently far over the filling nipple to couple the filling nipple to the closing element to block it against rotation. The closing element can only be turned if the connecting piece has been pushed sufficiently (completely) over the filling nipple so that the filling nipple is coupled to the closing element and blocks the latter against rotation. The connecting piece can only be slid sufficiently (completely) over the filling nipple in a certain position and also can only be removed from the filling nipple in this position. In this position the closing element is in the closed position so that the container can only be removed from the filling nipple in the closed position.
- Preferably, one side of the circumferential edge of the flange is provided with a protruding lip and/or a recess, and the boundary edge has an inverse shape. As a result, only containers that are provided with a connecting piece with a specifically shaped flange can be connected to a filling mouth intended for this purpose.
- The invention will be explained in more detail below on the basis of an exemplary embodiment of the connecting piece, a container provided with the connecting piece and an assembly of a container and a dispenser according to the invention shown in the drawings, whereby:

Figures 1 and 2 show adispenser 1 in the form of a dispenser for disinfection liquid. Thedispenser 1 is provided with adispenser nozzle 2 for dispensing dispenser liquid and a filling nipple 3 (seefigure 1 ) to which a connectingpiece 7 of acontainer 5 can be connected (seefigure 2 ). In this embodiment, thecontainer 5 is designed as a plastic bag, but can also be designed differently, such as for instance a bottle. - In
figure 3 thecontainer 5 is shown in cross-section. The connectingpiece 7 has ahousing 9 provided with acylindrical recess 11, which is open at itsaxial end 11a that protrudes from thepocket 6 and at the oppositeaxial end 11b. In thewall 13 of thehousing 9 near theend 11b there are two opposite throughopenings 15, via which the space in thebag 6 communicates with theopen end 11a of therecess 11. Therecess 11 can be closed at thisopen end 11a by acap 17 which is connected via aflexible hinge 19 to aflange 21 at theopen end 11a of therecess 11. - In
figure 4 the connectingpiece 7 is shown in perspective. On thehousing 9 there is acoupling piece 23 to which thebag 6 can be attached. Alip 25 is present on thecap 17 for easily pulling thecap 17 in the closed position out of therecess 11. Infigure 5 the connectingpiece 7 is shown from above. - During use, a
cylindrical closing element 27, shown in perspective inFigure 6 , is present in therecess 11 in the connectingpiece 7. This closing element is provided with afurther recess 29 which is also open at a firstaxial end 27a of theclosing element 27. Also in thewall 31 of theclosing element 27 near a secondaxial end 27b are two opposing throughopenings 33 formed by slots extending from theopen end 27a. Apartition 35 is present in therecess 29 for reinforcement. Infigure 7 theclosing element 27 is shown in top view. - For clarification, the connecting
piece 7 is shown in various views inFigures 8 and 10 and the connecting piece is shown in longitudinal section inFigure 9 . -
Figures 11 to 13 illustrate the cooperation between thehousing 9 of theconnector 7 and theclosing element 27. Thecylindrical closing element 27 is pushed with theclosed end 27b into thecylindrical recess 11, seefigure 11 . Therecess 11 is then closed by thecap 17, seefigure 12 . In this position, the closingelement 27 closes therecess 11 so that via theopenings 15 incoming liquid cannot escape. In this position of theclosing element 27, the connectingpiece 7 is properly closed and this position is particularly suitable for long-term storage of the liquid in the container. Therecess 11 in thehousing 9 and theclosing element 27 fit together clampingly, so that the outside of theclosing element 27 connects fluid-tight to the inside of therecess 11. - By pushing the
closing element 27 further into therecess 11, seefigure 13 , theopenings 33 in the closing element are positioned before theopenings 15 in the housing, so that the overlappingparts 37 of the two openings form a passage for liquid. By turning the closing element in this position a quarter of a turn, theopenings 15 are closed off by the wall of theclosing element 27. This position is particularly suitable during use where the container in which the connecting piece has been used, regularly runs empty and needs to be filled. - In
figures 14 to 17 the cooperation between the fillingnipple 3 and the connectingpiece 7 is illustrated. The closingelement 27 is slidable in the axial direction in therecess 11, between a first position in which theclosing element 27 is located at the location of aclosed part 13a (seefigure 9 ) of thewall 13 of thehousing 9, seefigures 14 and 15 , and a second position in which theclosing element 27 is located at apart 13b (seefigure 9 ) of thewall 13 in which theopenings 15 are present, seefigures 16 and 17 . -
Figure 14 shows the situation in which the connectingpiece 7 with the closingelement 27 is in the first position before it is slid onto the fillingnipple 3. In this position, the closingelement 27 is pressed into thehousing 9 when the container is manufactured. To fill the container, it is pressed with theclosing piece 7 onto the fillingnipple 3, whereby aprotrusion 39 of the fillingnipple 3 enters theslots 33 in theclosing element 27 and blocks theclosing element 27 against rotation relative to the fillingnipple 3, seefigure 15 . When pressing the fillingnipple 3 of the connectingpiece 7 further, the closingelement 27 is moved to the second position, seefigure 16 . Theopenings 15 in thehousing 9 are closed in this position of theclosing element 27 by wall parts of the closing element and theopenings 33 in theclosing element 27 are closed by wall parts of thehousing 9. In order to be able to fill the container, it must be turned a quarter turn, whereby the connectingpiece 7 also turns a quarter turn relative to the fillingnipple 3. This is shown infigure 17 . Theopenings nipple 3 into the container. - The connecting
piece 7 can only be slid onto the fillingnipple 3 and can only be removed from the fillingnipple 3 in a specific position. In this specific position, the closing element is in the closed position. This will be clarified below with reference tofigures 18 to 21 . Around the fillingnipple 3 of thedispenser 1 there is arecess 43 in thewall 47 of the dispenser, seefigure 19 in which the part A infigure 18 of thedispenser 1 is enlarged, but then viewed from above. - Part of the
boundary edge 45 of therecess 43 has a shape that is congruent with a side of theflange 21 that has a specific contour, seefigure 20 . In this embodiment, theflange 21 is rectangular and there is a protrudinglip 41 on this side of theflange 21. This protrudinglip 41 is at distance from the center of this side. As a result, the connectingpiece 7 can only be fitted completely onto the fillingnipple 3 in a specific position. A differently shaped flange of another container does not fit on the fillingnipple 3 of thisdispenser 1. - To open the connecting
piece 7, it should be rotated a quarter of a turn to the position shown infigure 21 . Under theboundary edge 45, which limits therecess 43, there is arecess 49 in which thelip 41 can rotate. In this position, the connectingpiece 7 is open and cannot be removed from the fillingnipple 3. In order to release the container from the fillingnipple 3, this together with the connectingpiece 7 must first be turned back a quarter of a turn to the position shown infigure 20 in which the connectingpiece 7 is closed again. - Although the present invention is elucidated above on the basis of the given drawings, it should be noted that this invention is not limited whatsoever to the embodiments shown in the drawings. The invention also extends to all embodiments deviating from the embodiments shown in the drawings within the scope of the invention defined by the appended claims. In the embodiment shown, the connecting piece serves for connecting the container to the filling nipple, so that the container functions as a reservoir for the dispenser. The connecting piece can also be used during filling of the container in a filling device, so that the container can be reused.
