Abstract
An assembly (1) of a venting mouth (2) and a cooperating cap (3) for being mounted to a container, wherein the cap is provided with a cap aperture (9) and the venting mouth is provided with a venting mouth aperture (6). The cap is movable with respect to the venting mouth (2) between an open condition in which a flow path (10) between the venting mouth aperture and the cap aperture exists and a closed condition in which the flow path is closed.
Description
- The present invention relates to an assembly of a venting mouth and a cooperating cap for being mounted to a container.
- Such an assembly is known in the prior art. When the assembly is mounted to a container the cap can be temporarily removed from the venting mouth in order to release overpressure from the container.
- An object of the invention is to provide an improved assembly of a venting mouth and a cooperating cap.
- This object is accomplished with the assembly according to the invention, wherein the cap is provided with a cap aperture and the venting mouth is provided with a venting mouth aperture, wherein the cap is movable with respect to the venting mouth between an open condition in which a flow path between the venting mouth aperture and the cap aperture exists and a closed condition in which the flow path is closed.
- An advantage of the assembly according to the invention is that it can be used for venting without removing the cap from the venting mouth.
- In the closed condition the cap and the venting mouth may contact each other at a sealing region which is located between the venting mouth aperture and the cap aperture.
- In a particular embodiment the venting mouth has a tubular portion including a venting plate at an inner side thereof, which venting plate is provided with the venting mouth aperture.
- The venting plate may be located at an axial end of the tubular portion of the venting mouth.
- The cap may have a closure plate opposite to the venting plate, which closure plate is provided with the cap aperture.
- In the event that the cap and the venting mouth contact each other at a sealing region in the closed condition the sealing region may surround the venting mouth aperture and extend up to the cap aperture. This means that the cap aperture and the venting mouth aperture are not located above each other which minimizes the risk of material falling through the cap aperture into the venting mouth aperture.
- In an embodiment the venting mouth aperture is surrounded by a rim at the sealing region and the cap is shaped such that in the closed condition the cap and the venting mouth contact each other at the rim and inside the rim.
- Preferably, the cap and the venting mouth are adapted such that the cap moves away from the venting mouth when the cap is moved with respect to the venting mouth from the closed condition to the open condition, wherein a retaining system prevents the cap from being separated from the venting mouth in the open condition, since the cap will not be separated from the venting mouth in the open condition.
- The cap may be a screw cap, which is advantageous in case of manually opening the cap.
- In the latter case the retaining system may comprise cooperating blocking elements at cooperating threads of the venting mouth and the screw cap.
- In a preferred embodiment the blocking elements are adapted such that they snap with respect to each other when turning the cap in a direction from the open condition to the closed condition and block with respect to each other when turning the cap in opposite direction, since this facilitates mounting the cap onto the venting mouth.
- The blocking elements may be wedge-shaped projections which are located between neighbouring ribs of the threads of the venting mouth and the screw cap.
- An advantage of applying the screw cap in combination with the retaining system is that when the cap has to be tightened, i.e. turned from the open condition to the closed condition, it is already positioned correctly with respect to the venting mouth.
- The invention will hereafter be elucidated with reference to the schematic drawings showing embodiments of the invention by way of example.
-
Fig. 1 is an exploded perspective view of an embodiment of an assembly of a venting mouth and a cooperating cap according to the invention in a disassembled condition. -
Fig. 2 is a similar view asFig. 1 , but showing the assembly from a different side and in an assembled condition. -
Fig. 3 is a perspective view of the cap ofFig. 1 as seen from a different side. -
Fig. 4 is a cross-sectional view of the assembly as shown inFig. 1 in an open condition. -
Fig. 5 is a similar view asFig. 4 , but showing a closed condition. -
Figs. 1-5 show different views of an embodiment of anassembly 1 of aventing mouth 2 and a cooperatingcap 3 according to the invention. Theassembly 1 is intended for being mounted to a container (not shown), for example a big bag. The assembly enables an operator to temporarily vent the container. Theventing mouth 2 has a tubular portion including a circular cross-section which is surrounded by acircumferential flange 4. Theflange 4 may be welded or glued to a container. - The
venting mouth 2 has anventing plate 5 at an axial end of the tubular portion thereof. Theventing plate 5 is provided with a plurality ofventing mouth apertures 6. In this case theventing mouth apertures 6 are formed by discrete arched slots at radial and angular distance from each other, but alternative shapes and dimensions are conceivable. -
Fig. 3 shows thecap 3 as a separate part. Thecap 3 is a screw cap and has an internal thread which cooperates with anexternal thread 7 of the tubular portion of theventing mouth 2. For clarity reasons the internal thread is not shown inFig. 3 . Thecap 3 has aclosure plate 8 which is located opposite to theventing plate 5 of theventing mouth 2 and which extends substantially parallel to theventing plate 5 of theventing mouth 2, seeFigs. 4 and 5 . Theclosure plate 8 is provided with a plurality ofcap apertures 9, in this case sixcap apertures 9, which are located at equiangular distance from each other in circumferential direction of thecap 3. Thecap apertures 9 are provided at thickened portions of thecap 3 which provide projections around thecap 3. The thickened portions reinforce thecap 3 at locations where thecap apertures 9 are provided as well as provide grip to facilitate manual turning of thecap 3 with respect to theventing mouth 2. - The
cap 3 is rotatable with respect to theventing mouth 2 between an open condition, as shown inFig. 4 and a closed condition, as shown inFig. 5 . In the open condition aflow path 10 between theventing mouth apertures 6 and thecap apertures 9 exists. In the closed condition theflow path 10 is closed. In the latter case theclosure plate 8 of thecap 3 and theventing plate 5 of theventing mouth 2 contact each other at asealing region 11 between theventing mouth apertures 6 and thecap apertures 9. Thesealing region 11 surrounds theventing mouth apertures 6 and extends up to thecap apertures 9. In this case thesealing region 11 is provided with arim 12 which surrounds theventing mouth apertures 6. In the closed condition thecap 3 and theventing mouth 2 contact each other at therim 12 and inside therim 12. - When the
cap 3 is rotated anti-clockwise with respect to theventing mouth 2 theclosure plate 8 of thecap 3 moves away from theventing plate 5 of theventing mouth 2 from the closed condition to the open condition, hence opening theflow path 10. - The assembly is provided with a retaining system which prevents the
cap 3 from being separated from theventing mouth 2 in the open condition. In the embodiment as shown in the figures the retaining system comprisescooperating blocking elements 13 at the threads of theventing mouth 2 and thescrew cap 3, seeFigs. 1 and3 . The blockingelements 13 are wedge-shaped projections which are located between neighbouring ribs of the threads and which snap behind each other when turning thecap 3 in a direction from the open condition to the closed condition. This means that thecap 3 can be turned in a direction from the open condition to the closed condition relatively easily in order to facilitate assembling the assembly, whereas theblocking elements 13 makes turning thecap 3 in opposite direction difficult when the cooperating blocking elements of thecap 3 and theventing mouth 2 contact each other. Hence, in the open condition thecap 3 cannot be turned further in a direction from the closed condition to the open condition easily. Thecap 3 can be turned from the open condition to the closed condition without being blocked. - The invention is not limited to the embodiment shown in the drawings and described hereinbefore, which may be varied in different manners within the scope of the claims and their technical equivalents.
