Definitions

  • This invention relates to an improved outlet for containers made of carton used for milk, juices etc.
  • spouts for containers made out of paper, for beverages and other liquids are known. They all consist of a body of plastic material and a lid of the same or different material. The lid is usually fastened to the body by an engaging thread. Both parts are injection molded.
  • the orifice of such spouts is usually sealed off by a membrane which is connected to the inner wall of the orifice by a thin web which acts as a predetermined breaking line. This membrane indicates temper evidence and is removed while initial opening by pulling a handle which is integrally connected to the membrane.
  • the handle of the spouts known from the state of the art has different shapes and is built in a way that it is not taller than the upper rim of the orifice.
  • a tearable membrane is located in the interior of the spout approximately midway of its height.
  • the membrane is concave and the pulling ring is horizontally disposed and arranged in a way that it stand not taller than the upper rim of the spout.
  • a tearable membrane is located preferably almost on the upper rim of the spout, leaving an only small part of the wall above it for proper air-tight resealing with the cap.
  • the pulling ring is located preferably well outside of the orifice of the spout and is parallel to the membrane No limitation of its size is given by the diameter of the orifice
  • the membrane is preferably neither flat nor concave but incorporates an asymmetric finger shaped depression.
  • the cap is designed in a way as not to compress and deform the pulling ring. The pulling ring remains unobstructed while standing taller than the upper rim of the orifice.
  • the spout disclosed in the present invention solves the problems known from the state of the art by a new arrangement and dimensioning of the membrane, the predetermined breaking line, the tear off handle and the orifice.
  • the tear off handle is preferably arranged in a way that it can be easily gripped without the necessity to insert a finger into the orifice It is positioned preferably above the upper rim of the orifice in a way that the size of the handle is not limited by the diameter of the orifice.
  • a tear off handle can be preferably built as a ring which is wide enough to be easily engaged with at least one finger.
  • the cross section of the tear off handle is dimensioned in a way that a certain bending stiffness and resistance against mechanical stresses is achieved.
  • the handle to remove the membrane is preferably connected in a pivotal way to the membrane by an element which comprises a locally bendable, hinge-like element, for example a strap made of highly orientated material. This material orientation helps to increase the mechanical resistancy and durability similar to film hinges of plastic closures.
  • the position of the injection point designated means and the local cooling of the mold, the flow of the material is guided and the necessary opening force is predetermined. Areas of defined cold-welding of the material can be obtained on purpose to influence the determined opening force.
  • FIG 1 shows a spout 1 in a perspective view.
  • the spout 1 consists of a body 2, a tear off handle 3, a membrane 4 and a predetermined breaking line 5.
  • the body 2 has a thread 6 to securely fasten a lid 20 (see Figure 2). It is evident, that the lid 20 can be fastened to the body 2 by any other suitable means.
  • the tear of handle 3 of the here shown embodiment has a ring-like shape. It is preferably enforced to obtain stiffness against bending in a rear area 7 where it is connected by region 8 of preferable bending (hinge like behavior) and a connecting element 9 to the membrane 4. It is evident that the tear off handle 2 can have any other suitable design.
  • the membrane 4 is arranged within the opening of an orifice 10 in the region of an upper rim 15.
  • the membrane 4 has a depression 17 for better finger access while operating.
  • a flange 16 is employed for the attachment of the spout to the carton preferably by ultrasonic welding.
  • FIG. 2 shows the spout 1 according to Fig. 1 and lid 20 in a side view.
  • the front part of the spout 1 and the lid 20 are cut off for better visibility.
  • the lid 20 comprises a thread 11 which is engaged with a thread 6 of the body 2.
  • a temper evidence ring 12 is integrally connected to the lid 20 by predetermined breaking elements 13.
  • the temper evidence ring 12 is engaged with a corresponding rib 14.
  • the predetermined breaking elements 13 are destroyed while first opening the lid 20 of the spout 1.
  • the tear off handle 3 is positioned preferably above the upper rim 15 such that it projects over the upper rim 15. In this position it can easily be held and operated and its size is not limited by the diameter of the orifice 10.
  • the reinforced rear area 7 is clearly visible.
  • the bendable region 8 and the connecting element 9 connect the tear off handle 3 and the membrane 4 in the embodiment shown here.
  • the membrane 4 is connected to the orifice 10 by the predetermined break off line 5.
  • the lid 20 is formed in a way, that it fits over the tear off element 3 and seals off the spout 1 while transportation after initial opening.
  • Figure 3 shows the first step of initial opening of the spout 1.
  • a consumer grabs the tear off handle 3 and pivotally rotates it in the direction of an arrow R by applying a force, schematically shown by an arrow P.
  • the tear off handle 3 rotates pivotally around the hinge-like bending region 8 in the embodiment described here.
  • This bending region 8 is formed by a thin area of very durable material which can be obtained by material orientation (according to film hinges of injection molded plastic closures).
  • the tear off handle 3 is rotated pivotally backwards until the reinforced rear area 7 comes in contact with the rim 15 of the spout 1.
  • the predetermined breaking line 5 starts to break initially and relieves the orifice 10 in a chain reaction.
  • the predetermined breaking line 5 is made in the here shown embodiment of a thin web of material. To support the above described effect this web can be designed to be less resistant in the region of the connecting element 9. This can be obtained by adjusting the thickness of the structure, the size of the radius and the angles of the cross-section.
  • the ration of B/A of a preferred embodiment is typically in the region of 5 to 10.
  • Figure 5 shows the membrane 4 ins completely removed position above the spout 1.
  • the orifice 10 is now completely open to pour out the stored liquid.
  • the spout 1 can be securely sealed repeatedly by unscrewing the lid 20 (see fig. 2). Due to the preferred position of the membrane 4 in the region of the upper rim 15 of the orifice 10, material reduction and better cycle times while production are obtained.
  • Figure 6 shows a membrane 4, a predetermined breaking line 5 and ring-shaped tear off handle 3 in a perspective, cut-off view.
  • the tear off handle 3 is connected to the membrane 4 by a bendable region 8 and a connecting element 9.
  • the predetermined breaking line 5 is formed by two rifts 18.1, 18.2.
  • the depth of rift 18.1 depends on the position. By changing the cross-section, the bottom radius and the depth of the rifts 18.1 and 18.2, the initial opening force is influenced.
  • the depth of the rift 18.1 is in the here shown embodiment deeper in the region of the connecting element 9, such that the thickness of the predetermined breaking line 5 is different and less force has to be applied to initially break the breaking line 5. After initially breaking a chain reaction is started and the rest of the predetermined breaking line is destroyed.
  • An injection point 21 for injecting the material is positioned in the here shown embodiment in the middle of the membrane 4.
  • the flow of the material is guided in a way that weak areas along the predetermined breaking line 5 are produced, whereby the force to remove the membrane 4 is controlled.
  • Additional elements 22 are placed if necessary on the membrane 4 and other elements. Theses elements 22 have influence on the flow of the material and the mechanical stiffness of the membrane 4.
  • Arrows 23 indicate the guidance of the material. It is self-evident, that these arrows 23 only indicate one possible way to influence the flow of the material. By guiding the material on different paths to the predetermined breaking line 5 and the partial cooling of the mold, areas of cold-welding result.
