Definitions

  • the present invention generally relates to the field of liquid packaging containers, and more particularly, is directed to a resealable beverage can end with a pour spout and a cap.
  • the can In on ⁇ ; embodiment of the invention, the can has an upstanding nee ' ., portion.
  • Cans of the type which are presently used for beverages are illustrated in prior art Figures 1-3.
  • Cans of this type became popular in the late 1950 's with the introduction of the "Soft Top” end illustrated in prior art Figure 1.
  • the state of the art advanced in the 1960 ' s with the development of the first integrated opening ends with a formed rivet and tab as illustrated in prior art Figure 2.
  • the beverage can end has changed from a 211 diameter at .0150" gauge and a net metal weight of 13.0#/M, to 206 diameter at .0096" gauge and 6.7 “ /M to 204 diameter at .0090" gauge and 5.9#/M to the present-day 202 diameter at .0085" gauge and 5.3#/M. Changes in can construction are expected to continue as material and manufacturing technology advances to higher level.3 while consumer demand is developing at the same time.
  • the present-day beverage can generally is made of a cylindrical panel body 10 of aluminum or steel drawn and shaped as known in the prior art to form an open ended can at the top/lid 7 and a closed off bottom 11.
  • the open end of the can includes a necked-in portion 9 which reduces the diameter of the opening.
  • the opening is closed by end/lid 7.
  • the smaller diameter produces a lighter end/lid material weight which at the same time provides higher buckling resistance values from inside package pressure for the circular end/lid 7.
  • the smaller diameter facilitates drinking from the can, especially by small children.
  • Figures 2 and 2A illustrate another construction of a prior art beverage can with a generally cylindrical panel body 5 forming a wall, a closed off bottom 6, a necked-in portion 4 and a lid 3 for closing off the open end of the can.
  • the necked-in portion 4 is not as great as the can necked-in portion 9 illustrated in prior art Figures 3.
  • a number of techniques are well known in the prior art for providing a convenience opening for drinking and pouring of the contents from the can.
  • One such technique is the well known can opener which pierces a generally triangular-shaped opening in the lid.
  • the disadvantage of this technique is that it requires the use of a can opener which may not always be available.
  • FIG. 1 and 1A Another technique is illustrated in prior art Figures 1 and 1A, and includes a ring tab 1 which when pulled, allows the lid 2 to be removed from its liquid tight engagement with the can.
  • a ring tab 1 which when pulled, allows the lid 2 to be removed from its liquid tight engagement with the can.
  • One disadvantage of this technique is that the lid at the moment when coming loose from the can body tends to vibrate and the liquid under the lid splashes out.
  • Another disadvantage of this technique is that the edge around the lid covering the entire ends periphery is often left sharp which constitutes a safety hazard.
  • the most popular present day technique for opening a beverage can is to use a lever operated push in gate. Such a technique is illustrated in prior art Figure 3A and 4. This technique also has certain disadvantages.
  • the can is opened by lifting up a lever 13 which pushes the gate 12 down into the can with the gate hinging inside the can during drinking.
  • the hygienic aspect of this technique is not healthy as the can's end becomes contaminated in some distribution chains and outlets.
  • Pushing the gate down is hard for individuals with weak fingers, for small children and for women with long fingernails. It is also uncultivated and highly unsanitary to push the gate into the can with a finger.
  • the gate will not pass out through the opening as the scoring line producing the disk/gate periphery and the gate/opening may be slightly damaged. Pushing in the gate and breaking the score of an already damaged scoring line, will result in an uneven score between the gate and the opening and produce a tolerance between the gate diameter and the opening diameter. If the gate meets the opening in the right position, the gate will pass out through the pouring area during drinking and could be inadvertently ingested by the user.
  • Damage to the scoring line in a gate end made of light weight material may occur in the distribution chain or from a dull scoring tool. Several million cans may be produced and reach the market place before such a problem surfaces.
  • a further problem with the push in gate concept is the fact that some gates will be pushed in from stacking during rough transportation of the cans around the country, thus resulting in leaking packages .
  • a resealable threaded can end comprising a complete combination of properties such as; low material consumption, high speed manufacturing capacity, condensed stacking, high pressure barrier, easy opening, controlled pouring, are not known in the state of the art.
  • a resealable hygienic can end, maintaining the pressure of carbonized beverages after opening, is according to several markets studies preferred by the consumers.
  • Another object of the present invention is to provide an improved can end which can be manufactured using conventional manufacturing techniques.
  • Another object of the present invention is to provide a can end which can be easily and inexpensively manufactured.
  • a still further object of the present invention is to provide a can body with a lighter weight material.
  • Figures 1A, 2A and 3A are top views of the cans illustrated in Figures 1, 2 and 3, respectively.
  • Figure 4 illustrates a can with a sectional view of a lever operated push in gate opening technique as known in the prior art
  • Figure 5 illustrates a can with a transverse sectional view of the can body and the end including the cap according to the present invention
  • Figure 5A is a top view of the can illustrated in Figure 5;
  • Figures 6 and 7 illustrate a manual push in gate technique of opening a can as known in the prior art
  • Figure 8 illustrates a sectional view of a can end with the cap in a closed position.
  • Figure 9 illustrates a sectional view showing how the can end's closing flanges interface with the caps closing flanges in a closed position.
  • Figure 10 illustrates a sectional view of the can end with the cap in an open position.
  • Figure 11 illustrates a sectional view of how the can end closing flanges is released from the cap's closing flanges when opened.
  • the can's cylindrical panel wall is made of aluminum or steel and the necked in cylinder panel wall top circumference is closed with an end as illustrated in Figure 8.
  • the can end is made of aluminum or steel with a traditional outer profile flange 14.
  • a well known profile flanging method is used to close the can's cylinder body and end together.
  • the circular profile flange 14 extends into conical and concentric panel 15, and furthermore into a conical neck part 16, with an upper circumference panel containing four male sealing flanges 17.
  • Flange 14 terminates with a circular pour opening having a folded hem 18.
  • a cap 22 is adapted to the conical neck part 16 for sealing the can and has a corresponding conical panel 19 for conical neck part 16. Cap 22 is further illustrated in Figure 9.
  • Cap 22 also has four female sealing flanges 20 having corresponding interlocking profiles with the conical neck N s four male sealing flanges 17. This construction provides a pressure tight seal when the cap is turned into place to close the can end.
  • a seal 21 is oriented between the folded hem 18 and the inside cap panel .
  • Figures 10 and 11 further illustrate the construction of the can end an cap in accordance with the present invention.
  • Figure 10 shows a sectional view of the can end with the cap in an open position while
  • Figure 11 illustrates a sectional view of how the can end closing flanges is released from the cap's closing flanges when opened.
  • neck part 15 produces higher buckle resistance values, due to inside pressure, for the conical end.
  • the horizontal circular part of flange 14 extends into the conical concentric end panel 15 at 115°. Buckle resistance values should, therefore, be higher for the conical ends. This allows for reduced material area weight compared to the current ends whose horizontal circular flange part extends to 90° into a plane circular end panel .
  • the conical shape also helps to reduce the angle at which the can must be held in order for the consumers to drink from the can.
  • the angle is reduced by about 35 percent. Such a reduction in angle allows the upper can body to fit more comfortably under the nose for drinking.
  • the upper portion of prior art cans tend to collide with the nose.
  • the consuming public has had good experience with consumers drinking beverages from bottles with replacable caps, as the consumers replaces the caps after having used the bottles .
  • the caps will stay on the can ends until reaching the recycling plant.
