No. 436,054 comprises a beak member lodged in a recess formed in the tube head as an oblique slot in a plane extending through the longitudinal axis of the tube, the beak member being hingedly mounted in the recess and being held in closed position by an elastic ring about the same.
  • Another known tube described in U.S. Pat. No. 2,755,974 granted on July 24, 1956, has a head part, a mouth part and a duct therethrough having a discharge orifice, a hose member lodged in the said duct, a slide member displaceable at a right angle to the longitudinal axis of the mouth part, and a blade spring exerting pressure on the hose but yielding to permit the discharge of paste from the tube when the latter is squeezed, the blade spring, slide member and hose being mounted in the tube head part devised as a housing therefor.
  • all previous attempts have failed to provide a closure device of the above-described type which would satisfy the two main requirements that must be met by such a device if it is to be commercially acceptable.
  • the construction of the closure device must be as simple as possible in order to permit a manufacture at costs which are not prohibitively higher and possibly even equal to those of manufacturing the well known types of screw cap closures for tubes; and, secondly, the novel closure device must be at least as safe in sealing its contents, or even safer than the hitherto known screw cap closures;
  • the beak means comprise a rigid portion
  • the head body has a recess for housing the elastically deflectable beak arm therein as well as a cavity open at the end of the recess away from the orifice and adapted to hold the aforesaid rigid beak portion firmly therein, while the elastically deflectable beak arm is biassed toward the flexible wall zone when in place withits free arm end against the last-mentioned zone at the orifice, such biassing being provided by a spring force inherently present in the deflectable beak arm due to tensioning of the latter.
  • the bottom of the recess is constituted, at least in the part thereof near and at the discharge orifice, by the elastically flexible wall zone.
  • tensioning is achieved by providing the beak means with an obtuse angle between the elastically deflectable arm and the rigid portion thereof, which angle is smaller when the beak means is untensioned, i.e., when it is not yet inserted, than when it is inserted with its rigid portion into the cavity of the head body, and before the free end of its elastically deflectable arm is in place against the flexible wall zone at the discharge orifice in the head body.
  • the invention provides a closure device which can be made up of only two separable parts.
  • a single manual operation is required whereby the user squeezes the wall of a collapsible tube remote from the discharge opening with, for instance, two fingers, or whereby he presses upon the closure device according to the invention, thereby opening the outlet valve of a pressure container when the closure device is used as an actuator for such a container.
  • the discharge opening will close instantly and hermetically, as soon as manual pressure on the tube wall or on the actuator ceases. Any residual contents ahdering to the outside of the closed discharge slit, when these contents are particularly sticky, can be easily wiped off whith a cloth.

  • a slit provided between the rigid wall part and an elastic, deformable wall portion, along which slit, when closed, the latter wall portion extends throughout in parallel with the rim of the rigid wall part and merges with the latter at an acute angle, free from any'rounded marginal wall portions causing bulging when being closed, ensures a greatly superior sealing effect achieved with a weaker bias on the free end of the beak member; and a correspondingly lower pressure increase is needed todischarge a part of the contents from the interior of the tube or container connectedto the closure device according to the invention.
  • the elastically deflectable arm is joined to the rigid beak portion forming an external shoulder which comes to rest on the upper end rim of the recess of the head body, in which the deflectable arm is lodged, while the rigid beak portion is inwardly displaced relative to the deflectable arm due to the said shoulder and is inserted in the above-mentioned deep cavity of the head body. Due to the fact that the'rigid portion is securely anchored in the cavity, the deflectable arm acts like a blade spring on the elastically flexible wall zone at the orifice at all times and is deflected outwardly by the bulging flexible wall zone when the internal pressure in the duct leading to the discharge orifice is increased, e.g. by squeezing the flexible wall ofa collapsible tube to which the closure device is permanently attached.
  • the deflectablebeak arm has its largest diameter at its juncture with the rigid beak portion, and is of gradually diminishing thickness toward the free end thereof,so as to obtain an optimal inherent spring effect when mounting the beak means in. tensioned condition into the head body.
  • a particularly safe sealing effect is achieved if the rim of the discharge orifice constituted by he rigid part of the wall portionsurrounding the discharge duct is of concave contour in the plane extending perpendicularly to the discharge duct axis, while the contact edge of the freeend of the deflectable beak arm is of correspondingly convex shape;
  • the rim of the rigid wall part can be of convex shape, while the shape of the terminal edge of the free end of the flexible beak arm is correspondingly concave.
  • the sealing effect can also be enhanced by providing a groove across the contact face of the rigid wall zone adjacent the discharge orifice and a corresponding bead across the contact edge ofthe free end ofthe beak arm, or vice-versa, which groove and bead means extend preferably at a right angle to the discharge duct axis.
  • the beak means may comprise an arresting device which prevents an opening of the discharge orifice due to unintentional application of pressure on the wall of a collapsible tube bearing the closure device, or on the latter while attached to a pressurized container, for instance during storage or travel.
  • the arresting device When the tube or other container is to be used, the arresting device is disengaged,and there is no need to reengage it during the remainder of its use except, possibly, as a safety measure, whenpacking away the tube or pressure container for travelling'ln a preferred embodiment of the arresting'device, the closing edge at the free end of the de flectable beak arm is so devised that it will hold the orifice hermetically closed, at and between two limit positions superimposed in the direction of the discharge duct axis.
  • Securing means such as projections or grooves or abutments are provided at the beak means and at the adjacent wall of the recess of the head body in which the beak means is lodged, whereby the deflectable beak arm can be rigidly connected to the head body when these arresting means are engaged. They can be released, and the beak arm can be deflected to open the orifice, by simply pushing the beak means in the recess a short distance toward the discharge orifice.

  • Wall portion 2 of head body 1 should surround the orifice 4 uninterruptedly and is preferably integral with the remainder of head body 1. When closed, orifice 4 appears as a hermetically sealed slit in the top face of head body 1.
  • This zone thus extends from the orifice over at least part of the length of wall portion 2 toward the opposite duct opening.
  • the thickness of this flexible zone of wall portion 2 depends on the elasticity of the material from which the head body and the wall portion therein are made. It also depends on the viscosity of the product to be discharged, which is also a factor in determining the length, in a direction transverse to the duct axis, of the slit which is constituted by the closed orifice.

  • elastic arm 7b is at all times biassed against the flexible wall zone 6 at orifice 4.
  • friction between the side walls of rigid beak portion 7a and the inner walls of cavity 11 is so increased that the beak member is prevented from falling out or being pushed out of cavity 11, when a pressure increase occurring in duct 3 in the direction toward discharge orifice 4 is transmitted to the beak member 7.
  • the slight curvature of the elastic arm 7b of beak member 7 helps to increase the desired bias and also adapts the outside face of the beak member smoothly to the overall rounded surface of head body 1.
  • This bias of elastic arm 7b increases as the pressure inside duct 3 is increased either by manual squeezing of the flexible wall of a collapsible tube connected leak-free to the inside open end of duct 3 away from orifice 4, or by depressing head body 1 when the latter is mounted on a movable member of the outlet valve of a pressure container, whereby the pressurized contents of the latter can penetrate into duct 3 andpressure against the flexible wall zone 6 at orifice 4 rises.
  • Flexible wall zone 6 is thereby deformed and/or expanded to move away from the closing edge 5a of rigid wall zone 5, pushing the lip part 70, and thereby bending the arm 7b, away from closing edge 5a in the direction of arrow P as shown in FIG. 4, and opening the orifice 4, while at the same time the resulting increased bias of beak arm 7b lasts as long as the increased pressure prevails in the interior of duct 3.
