  • a downwardly projecting probe may hit the inner wall structure 184 which will direct the probe inwardly toward the membrane.
  • the engagement of the probe with the membrane occurs at a point that is spaced apart from the membrane engagement flange 66 and thus, an additional measure of give is observed.
  • the inwardly sloping angle is configured to slope inwardly at an acute angle of approximately 20° to 50°, however, the invention is not limited thereto.
  • the configuration of the membrane enhances the ability to withstand impacts from the downwardly projecting probe.
  • the sidewall structure and the connector region are configured to both deflect and to direct the probe toward the valve opening.
  • the inner surface 96 is inclined inwardly to urge the probe toward the valve opening.
  • the lower portions of the sidewall structure have less deflection, due to the greater thickness to further urge the probe toward the valve opening.
  • the greater thickness and the inward protrusion further provide additional protection to the membrane to promote the integrity of the membrane.
  • the cap can be snapped onto the spout and then twisted off the spout by hand (or vice versa, for example). This allows for the removal without the use of a tool. It will be understood that the spout therefor has two different means of attachment. To facilitate such a dual attachment, especially in an environment wherein a probe is extended through the membrane, durability and resistance to movement are different than for caps that do not have only a single means of removal.
  • the continued movement of the fitment onto the spout is limited by the stopper flange that extends inwardly from the inner surface of the outer depending annular member.
  • the stopper flange interfaces with the upper annular rim flange 306, thereby limiting movement and precluding engagement between the distal end of the outer depending annular member and the upper surface of the upper flange, as well as precluding engagement between the upper annular portion and the upper annular rim flange.
  • the upper annular rim flange can be deflected by the stopper flange so as to provide additional force resisting disengagement.
  • the stopper flange is spaced apart from the upper annular portion, thereby leaving a space between the rim flange and the upper annular portion. Such a spacing provides improved snap on capabilities to the cap by allowing the deflection of the outer depending annular member about a region that is spaced apart from the stopper flange.
  • the distal end of the outer depending annular member 204 is spaced apart from the upper flange 304 of the spout. Indeed, when fully in the installed configuration spacing separation remains. Such a configuration allows for grasping between these elements (to aid removal, for example). Additionally, the configuration precludes interaction between the cap and the upper flange 304 even where the installation (i.e., the insertion of the probe) may cause deflection or relative movement between the cap and the spout. Furthermore, the distal end is chamfered to further limit the interaction between the distal end and the spout, while providing support for the thread positioned on the inner surface thereof.
  • the distal end of the inner depending annular member 202 extends at least close to even with, or, preferably even beyond, the distal end of the outer depending member, while being inwardly tapered. As such, while providing additional stability and integrity to the inner depending annular member (while also providing support for the membrane), such a configuration provides an enhanced structural channel between the inner and outer depending annular members.
  • the thread of the spout is spaced apart from the upper annular rim flange (and the thread tapered to maintain the gap), thereby allowing both the threads to flex and the upper annular rim flange to flex without interfering with each other.
  • the threads of the body remain spaced apart from the stopper flange and maintained entirely within the lower portion of the inner surface.
  • the entire region upon which the thread is positioned is configured to fiex more easily than the region above the stopper flange.
  • the separation between the stopper flange and the thread likewise provide improved flexing.
  • outer annular bulge 214 and the grasping flange 219 are spaced apart from the stopper flange and positioned at or near the proximal end 246 of the outer surface of the outer depending annular member.
  • the location of the end of the spout is spaced apart from the grasping flange, increasing the mechanical advantage to separate the two.
  • the increased annular thickness required by the grasping flange can be minimized due to the position of the same with respect to the proximal end of the outer depending annular member.

Abstract

La présente invention concerne un ensemble à bec verseur et à raccord auto-collant comprenant un bec verseur et un raccord auto-collant. Le bec verseur et le raccord sont conçus pour permettre d'appuyer le raccord sur le bec verseur, des filets correspondants sur chacun d'eux se mettant en prise de manière correspondante, ce qui permet de retirer le bec verseur et le raccord en les dévissant. Le raccord peut également être déboîté du bec verseur.
