Description

Title: System for transporting and storing a liquid and for transporting said liquid from the container to a destination outside of the container
The present invention relates to a system for transporting and storing a liquid and for transporting said liquid from the container to a destination outside of the container. The system is in particular suitable for safe transfer of liquids according to a 'closed transfer system', in particular to transfer crop protection products into a sprayer.
Such a system according to the preamble of claim 1 is well known and commercially available from the applicant. It is described in WO99/05446, the content of which is considered to be incorporated by reference. The known systems have a small bore, in the order of several millimetres.
The aim of the invention is to provide such a system suitable for large diameter bores, in particular exceeding 30mm. It has been found that when the known cap assembly is scaled up to a bore having a diameter exceeding 30mm, e.g. to be assembled onto a container comprising a relatively large inlet opening, in particular exceeding 30mm, in particular industry standard containers with 63mm closures, unintentional release of the plug occurs. In order to ensure a closed transfer system, the cap assembly is to be assembled onto the container straight after the filling of the container. Hereafter, the containers are transported to the site where the liquid is to be used. During transport there is a risk of dropping such a container filled with liquid. As the container is closed, liquid sloshing in the container, e.g. as a result of dropping, causes a hydrodynamic load exerted onto the plug of the cap assembly, and hence increases the risk of unintentional release of the plug.
The invention aims to provide a system suitable for bores comprising a diameter exceeding 30mm.
This aim is achieved in that a seal cover is provided over the bore, essentially parallel to the plug, which serves to close off the bore airtight. Such an airtight seal cover over the bore, parallel to the plug, counteracts possible hydrodynamic loads caused by sloshing and hence the risk of unintentional release of the plug is significantly reduced. Advantageously, the bore is large, e.g. having a diameter exceeding 30mm, in particular 45 mm, in particular 60mm or even larger. In a preferred embodiment, the inner wall of the cylindrical body further comprises a seal cover seat at an end adjacent the insert opening, extending around the bore, for a seal cover which serves to close off the bore airtight, and the essentially cylindrical body comprising a seal cover abutment surface for the seal cover, the seal cover abutment surface extending radially adjacent the insert opening,
the seal cover being provided with a sealing system with at least one radially deformable seal element adapted to releasably engage with the seal cover seat,
the seal cover being designed such that in a transfer position the seal cover abuts against the seal cover abutment surface and the seal elements abut against the seal cover seat, thereby covering the insert opening airtight.
The invention is further elucidated in relation to the drawings, in which:

Figs. 1 a-1 c and figs. 2-6 show different views and details of a similar embodiment of a system of the invention. Same parts are given same reference numerals. In figs. 1 a-1 c, an entire system for transporting and storing a liquid and for transporting said liquid from the container to a destination outside of the container is shown. The system comprises: • a container for transporting and storing a liquid, comprising a container body provided with a neck portion 2;
• a cap assembly 10 secured on the neck portion for fluidly-tight closing the container body;
· a coupler assembly 30 configured to be mechanically coupled to the cap assembly 10 so as to achieve a coupled configuration for a liquid connection to and/ or from the container, comprising a male probe 31 to be connected to a female part 1 1 of the cap assembly. In particular, the neck portion 2 surrounds an inlet opening 3, in particular an inlet opening having a diameter exceeding 30mm, in particular 45 mm, in particular 60mm or even larger.
The cap assembly 10, shown in other views in figs. 2-5, comprises the female part 1 1 and a plug 20, the female part having an essentially cylindrical body comprising two concentric interconnected cylindrical walls 12, 13 defining there between a cylindrical slit 14 having an open end 14a and a closed end 14b where the outer cylindrical wall 13 is connected to the inner cylindrical wall 12. The slit is adapted to receive, at the open end thereof, the neck portion 2 of the container body to provide a fluid-tight closure around the neck portion. In the shown embodiment, , the container is positioned with its neck portion downwards, and hence the open end of the cylindrical slit corresponds to top end and the closed end to the bottom end. It is also conceivable that the container is positioned with its neck portion upwards, allowing the the cap assembly to be positioned over the neck portion. In the shown embodiment, a seal ring 15 is provided at the closed bottom end of the cylindrical slit 14b to assist the fluid-tight closure of an upper end 2a of the neck portion 2 of the container body by the female part 1 1 of the cap assembly.
In the shown embodiment, the cylindrical slit 14 comprises a slit engagement surface 14c, here provided at the outer cylindrical wall. It is also conceivable that the slit engagement surface is provided at the inner cylindrical wall, or at both walls. The slit engagement surface is adapted to engage with a corresponding neck engagement surface 2c at the neck portion 2 of the container body to provide a fluid-tight closure around the neck portion. The slit engagement surface and corresponding neck engagement surface are here formed by cooperating screw thread. Other engagement mechanisms, e.g. involving a rim and a recess, are also conceivable. In the shown embodiment, the outer cylindrical wall 13 is provided with a tamper-evident ring 19, here extending as a continuation of the outer cylindrical wall. This tamper-evident ring has to be removed to be able to remove the cap assembly from the neck portion of the container body. Accordingly, one can determine from the status of the tamper-evident ring whether the cap assembly has been removed from the container or not.
It is noted that in figs. 2 and 3 the inner cylindrical wall 12 comprises a shallow slit 12c at end 12a adjacent the plug opening 18. In the shown embodiment this is provided for constructive purposes relating to injection moulding.
The inner wall of the cylindrical body 12 defines an axial bore 16 extending from an insert opening 17 for the male probe through the body to an opposed plug opening 18. The openings of the shown embodiment are of similar dimension. The insert opening and plug opening are provided at opposed ends of the body. When the cap assembly 10 is engaged with the neck portion 2 of the container body, the inlet opening 3 is within the axial bore 16.
The inner wall of the cylindrical body 12 comprises a seat 12b adjacent the plug opening 18, extending around the bore 16, for the plug 20 which serves to close off the bore fluid-tight.
This plug and its operation has extensively been described and disclosed in WO99/05446. The bore of the female part between the insert opening 17 and the seat 12b comprises a shoulder 12d, facing towards the insert opening. The plug 20 is provided with a hooking system with multiple elastic hooking parts 21 a, 21 b, 21 c, 21 d, 21e, with corresponding hooking surfaces 21 a", 21 e". As visible in fig. 1 a, at least one of the hooking parts rests in a first position with its hooking surface against the shoulder, in which first position the plug 20 closes off the bore and hence fluidly-tight closes the plug opening of the container body.
The coupler assembly 30 has a male probe 31 with a head and a recess 33 located behind the head for receiving at least one of the hooking parts of the plug when the male probe is inserted into the bore, in particular at least one of surfaces 21 a', 21 b', 21 c', 21d', 21 e' of the hooking parts, so that the plug connects with the male probe. Radially next to the at least one of the hooking parts in its first position there is a space 22 between the hooking part 21 a, 21 b, 21c, 21 d, 21 e and the female part 1 1.
The at least one hooking part is designed such that - when the male is inserted into the bore - the head 32 of the male probe pushes the hooking part from its first position into this space 22 to a second position which is located radially further outward compared with the first position, in which second position the plug still closes off the bore and hence fluidly-tight closes the plug opening of the container body. The at least one hooking part is further designed such that at least one of the hooking parts, after axially passing the head 32 of the male probe towards a bottom of the container body, springs elastically inward to a third position and falls into the recess 33 of the male probe while contact between the hooking surface and the shoulder is maintained and while the contact between hooking surface and shoulder is maintained the plug still closes off the bore and hence fluidly-tight closes the plug opening of the container body.
The recess 33 in the male probe is such that a radial space is present between the hooking part 21 , located in its third position, and the male probe 31 , in such a way that inserting the male probe 31 further into the bore 16 towards a bottom of the container body causes the hooking part 21 to pass the shoulder 22 in the bore, the hooking part moves under the influence of a force exerted by the shoulder of the bore on the hooking part to a fourth position, as visible in Fig. 1 c, which is located further inward in the recess 33 compared with the third position, such that the plug engaged with the male probe opens the bore and hence allows fluid to pass from and to the container body.
Advantageously, the connector assembly has been designed such that the plug 20 is free of the bore 16 when the male probe has been inserted fully into the bore, with at least one of the hooking parts 21 of the plug 20 springing back elastically from the fourth position to the third position when it comes out of the bore.
The shown male probe has an internal axial passage 101 for passage of the fluid in which one or more ports 105 are provided, each extending from the outer surface of the male probe to an outlet in the axial passage. According to the present invention, a seal cover 45 is provided over the bore 16, essentially parallel to the plug 20, which serves to close off the bore airtight. In particular, the shown seal cover 45 comprises a seal surface 40 extending across and parallel to the insert opening 17. The seal cover 45 is shown in detail in fig. 6. Alternative configurations of a seal cover are also conceivable as long as the bore is closed off airtight. For example a topseal or the like can be applied as well. In the shown embodiment, the inner wall 12 of the cylindrical body further comprises a seal cover seat 12f at an end 12e adjacent the insert opening 17, extending around the bore 16, for the seal cover 45. Further, in the shown embodiment, the essentially cylindrical body comprises a seal cover abutment surface 12h for the seal cover, the seal cover abutment surface extending radially adjacent the insert opening.
The seal cover is here provided with a sealing system with at least one radially deformable seal element 41 adapted to releasably engage with the seal cover seat 12f, here is a radially expandable and compressible ring-shaped collar extending perpendicular to the sealing surface of the seal cover. The seal cover is designed such that in a transfer position the seal cover abuts against the seal cover abutment surface 12h and the seal elements abut against the seal cover seat, thereby covering the insert opening airtight.
Furthermore, in the shown embodiment, the seal cover is provided with a tamper-evident tear ring 42 extending around the essentially cylindrical body, which has to be removed prior to the removal of the seal cover. In this embodiment, the tamper evident ring 42 comprises a rib 42a engaging below a thickened end rim 12g of the inner wall 12

3. System according to claim 1 or 2, wherein the inner wall (12) of the cylindrical body further comprises a seal cover seat (12f) at an end (12e) adjacent the insert opening (17), extending around the bore (16), for the seal cover (45),
the seal cover being provided with a sealing system with at least one radially deformable seal element (41 ) adapted to releasably engage with the seal cover seat (12f).
4. System according to one or more of the preceding claims, in which the at least one radially deformable seal element is a radially expandable and compressible ring-shaped collar extending perpendicular to the sealing surface of the seal cover.
5. System according to one or more of the preceding claims, wherein the seal cover is provided with a tamper-evident tear ring (42) extending around the essentially cylindrical body.
6. System according to one or more of the preceding claims, wherein the outer cylindrical wall (13) being provided with a tamper-evident ring (19), preferably extending as a continuation of the outer cylindrical wall.
7. System according to one or more of the preceding claims, wherein a seal ring (15) is provided at the closed end of the cylindrical slit (14b) to assist the fluid-tight closure of an upper end (2a) of the neck portion (2) of the container body by the female part (1 1) of the cap assembly.
8. System according to one or more of the preceding claims, wherein the cylindrical slit (14) comprising a slit engagement surface (14c) adapted to engage with a corresponding neck engagement surface (2c) at the neck portion (2) of the container body to provide a fluid-tight closure around the neck portion.
9. System according to one or more of the preceding claims, wherein the connector assembly has been designed such that the plug (20) is free of the bore (16) when the male probe has been inserted fully into the bore, with at least one of the hooking parts (21) of the plug (20) springing back elastically from the fourth position to the third position when it comes out of the bore.
10. System according to one or more of the preceding claims, wherein the male probe has an internal axial passage (101) for passage of the fluid in which one or more ports (105) are provided, each extending from the outer surface of the male probe to an outlet in the axial passage.
