Abstract
In a vented spout assembly for threaded engagement onto a fluid container, a flexible spout is provided comprising a first tubular portion with a connected cap, at least one corrugated flexible section, and a second tubular portion with an end face. The cap has at an end surface a vent structure having a flexible tube section and a slit in a side wall of the tube section and extending longitudinally. The slit has first and second abutting end faces. The first tubular portion has at least one internal projection extending inwardly from a side wall of the first tubular portion and which is positioned to contact the end face of the second tubular portion when the second tubular portion is inserted through the cap into the first tubular portion to prevent a leading corrugation of the at least one corrugated flexible section from engaging any thread of the cap.
Description
- It is known to provide a vented spout assembly for screwing onto a threaded outlet of a fluid container. See, for example, U.S. Pat. No. 8,727,187. A flexible spout is attached to a cap having threads. The cap can be screwed onto the threaded outlet of the container. A vent is mounted on the cap permitting air to enter the container when the container is being emptied to facilitate the emptying by preventing development of a suction in an air pocket above a fluid within the fluid container. More specifically, the vent on the spout cap is an air ingress tube with a one-way valve at one end of the air ingress tube comprising a check valve, such as a rubber duckbill valve having an air exit into the fluid only at the end of the tube. Such a small air exit limits the air flow and thus retards flow of liquid from the container. The flexible spout connected to the cap can be folded into a storage position for transport of the spout assembly by inserting a second tubular portion of the flexible spout through the cap and into a first tubular portion of the spout connected to the cap. Engagement of the second tubular portion of the spout in the first tubular portion occurs by engaging at least a leading corrugation of a corrugation section connected to the second tubular portion with one or more of the threads of the cap. The contact pressure by the corrugation or corrugations on the thread or threads can damage the threads, such as during storage or shipment. If the threads are damaged then when the cap is screwed onto the container threaded outlet leakages may result.
- In a vented spout assembly for threaded engagement onto a fluid container, a flexible spout is provided comprising a first tubular portion with a connected cap, at least one corrugated flexible section, and a second tubular portion with an end face. The cap has at an end surface a vent structure having a flexible tube section and a slit in a side wall of the tube section and extending longitudinally. The slit has first and second abutting end faces. The first tubular portion has at least one internal projection extending inwardly from a side wall of the first tubular portion and which is positioned to contact the end face of the second tubular portion when the second tubular portion is inserted through the cap into the first tubular portion to prevent a leading corrugation of the at least one corrugated flexible section from engaging any thread of the cap.

FIG. 2 is a side view of the vented spout assembly detached from the container; -
FIG. 3 is a side view of the vented spout assembly having a flexible spout thereof folded at one end around 180° and inserted through a cap of the spout assembly which is also folded around 180° but in an opposite direction to create a shipping or transport configuration; -
FIG. 4 is a fragmentary side view from a direction perpendicular to that shown inFIG. 3 showing preventing further insertion into a first tubular portion of a second tubular portion at an end of the flexible spout by respective internal projections formed as dimples on the first tubular portion functioning as an insertion stop; and -
FIG. 5 is an end view from a left of the cap of the vented spout assembly shown inFIG. 2 and illustrating the internal projections on the first tubular portion of the spout assembly and also showing a vent structure of the spout assembly. - For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the preferred exemplary embodiments/best mode illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, and such alterations and further modifications in the illustrated embodiments and such further applications of the principles of the invention as illustrated as would normally occur to one skilled in the art to which the invention relates are included herein.
- The vented spout assembly of one exemplary embodiment is shown in
FIG. 1 generally at 12 and which is threaded onto a threadedoutlet 11A of afluid container 11. Asfluid 6 is emptied from thecontainer 11 through thespout assembly 12 air passing through avent structure 14forms air bubbles 15 influid 6 which travel toair pocket 7 above thefluid 6 and which prevent a vacuum from developing therein which would impede out flow of thefluid 6 through thespout assembly 12. Threadedoutlet 11A on thecontainer 11 havingthreads 11 AA engage withthreads 13A oncap 13 of thespout assembly 12. - As shown in
FIG. 2 , thespout assembly 12 is formed of a flexible spout 9 having a firsttubular portion 17 connecting tocap 13 atend surface 13C with a center line of the firsttubular portion 17 being offset relative to a center of thecap 13. The firsttubular portion 17 is followed by a first corrugatedflexible section 20, an intermediatetubular portion 22, a second corrugatedflexible section 21, and a secondtubular portion 23 having anend face 23A. The first corrugatedflexible section 20 is formed of a plurality offirst corrugations 20A and the second corrugatedflexible section 21 has a plurality ofcorrugations 21A. - The first
tubular portion 17 has first and secondinward projections tubular portion 17 and shaped as dimples. The first tubular portion also has inwardly projectingrectangular finger grips 18A. These finger grips decrease an internal diameter where they are located of the firsttubular portion 17. - The
cap 13 has at theend surface 13C a leadingend 13B, and thethreads 13A. Adjacent the firsttubular portion 17 thevent structure 14 is provided in anaperture 13D in theend surface 13C in a pressed fit relationship to receive thevent structure 14. Thevent structure 14 is formed of a flexible rubber and has aflexible tube section 14D terminating in a V-shaped termination end 14C. Significantly aslit 14A is provided in the side wall of theflexible tube section 14D, the slit extending substantially from a region adjacent the leadingend 13B of the cap and terminating at a beginning of the V-shaped termination end 14C of thevent structure 14. - When fluid is being emptied from the
container 11, abutting end faces at theslit 14A separate, allowing air to pass through to form thebubbles 15. When not emptying the container the slit end faces abut against each other forming a substantial seal preventing liquid from entering thevent structure 14 and thus inhibiting leaking of thefluid 6 through thevent structure 14 when the container is not being emptied. - By providing the slit longitudinally along the tube section rather than horizontally at the end the length of the slit is substantially increased so that liquid from the container can be dispensed substantially faster, and final remnants of the liquid in the container can be dispensed more completely.
- As shown in
FIG. 3 the flexible spout 9 can be arranged in a storage or shipping mode such that the secondtubular portion 23 with itsend face 23A is inserted through thecap 13 and into the firsttubular portion 17. The secondtubular portion 23 has a narrower outer diameter than an inner diameter of the firsttubular portion 17 to allow a cocking or tilting as shown inFIG. 3 such that a longitudinal center line of secondtubular portion 23 when inserted into the firsttubular portion 17 is cocked or tilted at an angle with respect to a longitudinal center line of the firsttubular portion 17, thus allowing a peripheral portion 23AA of theend face 23A to be frictionally engaged with an inner sidewall of the firsttubular portion 17. Further it may be observed inFIG. 3 that theend face 23A butts up against at least one or potentially both of the inwardly projectingdimples FIG. 5 ). - By use of the
dimple projections tubular portion 23 into the firsttubular portion 17 is prevented, thus resulting in agap 24 between a first leading corrugation 21AA and the leadingend 13B of thecap 13. This prevents any engagement by the first leadingcorrugation 21 AA with theinternal threads 13A of thecap 13. This is significant since damage to one or more of the threads by the corrugation or corrugations is prevented. If the thread or threads are damaged such as by deformation leakages can result when the cap is screwed on the container. - In addition to the peripheral portion 23AA portion having frictional engagement because of the cocking of the second
tubular portion 23 in the firsttubular portion 17, frictional engagement may also occur between an outer peripheral portion of a side wall of the secondtubular portion 23 at location 23AB, which is at a corner between theend surface 13C of thecap 13 where it merges with an end of the firsttubular portion 17. These frictional engagements at 23AA and 23AB contribute to retaining the secondtubular portion 23 within the firsttubular portion 17 during shipment and/or storage of the spout assembly. - Although preferred exemplary embodiments are shown and described in detail in the drawings and in the preceding specification, they should be viewed as purely exemplary and not as limiting the invention. It is noted that only preferred exemplary embodiments are shown and described, and all variations and modifications that presently or in the future lie within the protective scope of the invention should be protected.
