Abstract
ABSTRACT OF THE DISCLOSURE
A closure for beverage cans and other containers is disclosed which prevents unintentional emptying thereof and which also prevents an undesired emptying after containers of liquid or viscous material are first opened, since action is only necessary to overcome a spring tension during the intended removal, as a result of which one can not only avoid undesired emptying but also prevent possibly dangerous insects from entering the can. Also disclosed are reusable closures or those for reusable containers.

Description
. ~ 2 ~ .? ~
The invention concerns a package, in particular a beverage can, having a sealed lid and a first closing device which unseals at least one lid opening, and having a second closing device in the form of a spring located on the inside o~ the lid, which keeps the lid opening closed from the inside after th~ lid opening has been unsealed and is connected to a manipulating device on the outside o~ the ~an for releasing it.
Containers made of metallic substances or containers combined with such substances are widely preferred today~ By way of example, beverags cans are commonly produced which consist of an actual can body and a separate lid. T~e contents to be packaged, for example a beverage, are filled into the can body before the lid is then tightly joined with this can body. In this way, a container is made which can withstand a ~all ~rom a great height, whereby the impact forces can cause a deformation and yet the content does not generally laak. Heat and cold are ~uickly conducted by the package material as a result of which these kinds of containers can be more easily and quickly cooled. If, in this case, a critical temperature is not reached or is exceeded, then the metallic package is not as guickly damaged as, for example, glass.
There may be numerous reasons which motivate manufacturers and consumers to use this type of package.

container itsel~ with the second hand or to find complicated alternative means.
Beverage cans, in particular, have a significant place among travel supplies. However, those beverage cans whose contents include caf~eine or the like, as well as lemonade-like beverages but also all alcoholic beverages attract insects. These insects, in particular, wasps, tend to crawl unnoticed into the cans and can then be easily swallowed by a person subsequently drinking the beverage.
With the insect thus swallowed, often half-dead, reflexive stinging can still occur in the eusophagus, resulting in internal swelling which can often lead to death. In this connection, it is known from US Patent 20 31 845 to provide the lid with a second closing device on the inside of the lid. This second closure is in the form of a spring and seals the lid opening from the inside after a ~irst closure has been removed and thus unsealed. In this case, it is disadvantageous that the ~irst closure on the outside is in th~ form of a dispo~able part. Moreover, to operate, i.e.
to open the second closure on the inside, a second lid opening is required through which it must be pressed out of its sealed position~ This second lid opening results in increased production costs, ~ince this second opening must also be sealed and since it o~fers an additional po~sibility for the beverage to run out or leak u~intentionally, for example when the can tips over.
It is an object of the present invention to provide a closure for a beverage can having a second closing device which ayain closes the outlet opening after the initial tearing open, which can be manufactured with low production co~ts and which requires only modest material expenditure~
This object is solved thereby that the ~irst closing device, which remains on the lid, can, in a working conneation with the second closin~ device, be used for repeated, a~dit1onal openings. As a result of these ' .
. , .. . . . . ..
~ 3 features, a closure for a beverage can is created in which the sealing first closing device remains connected with the lid and does not result in an aclditional disposable part, it is rather used as a manipulating part for opening the second closing device against ilts ~pring tension. After unsealiny, the liquid is prevented from running out of the can and other subskances are stopped from entering. A
beverage can is thus created in which a second closure in the Xo~m of a spring works on the lid opening on the inside in such a way that the latter continues to remain sealed, ev~n after :the first opening, and secured against unintentional emptying. The first closure in the form o~
a tear~open ring overcomes the spring tension of the second closure with its lever arm and presses this second closure .: .
into the can during an intentional withdrawal.
Embodiments of the inventin will now be de cribed, by way of example, with reference to the accompanying drawings, in which:
Figure 1 is a sectional view showing a beverage can r~ady for use and provided with closing devices in accordance with a~ e~bodiment of the invention; and Yigure 2 is a similar sectional view of the can of Figure 1, having a ~irst closure turned through 180 to the opposite side after a first opening.
Referring now to Figure 1, a beverage can l is sealed with a lid 2. A first closuxP 3 having a connecting means; 5, ~or example~ a rivet or a welding spot, i5 fastened to the outer top side oP the lid 2. The first closure 3 is made as a pre~ormed seal which closes the can ~ opening 6 and is designed as a tear-open device. A second clo~ure 4, which is connected via r.ivet 5 to the first closure 3, is provided on the botkom side o~ the lid 2 on the inside thereof. The second closure 4 can be provided with ~ sealing layer 7 on its top side facing the lid 2.
As shown in Fig. 2, a one-hand removal is possible since the beverage can 1 aan be held with one hand and at : :
.
the same time the index finger can be pushed under the first closure 3 which is in the ~orm of a tear-open device.
The first closure 3 is designed as a two-armed lever whose longer lever arm can be moved upward with the inde~ ~inger, while the ~horter lever arm is moved downward through the can opening 6 against the spring-~locking second closure 4~
The first closure 3 can thereby he turned about rivet 5 through 180 into a position actin~ against the seoond closure 4.
The entire device can be easily manufactured since the second closure 4 is merely connected with the lid 2 and the first closure 3 via suitable connecting means, for example, a rivet 5 fastened through the can lid 2, or a comparable arrangement.
In principle, khe hitherto existing can closure could be omitted. However~ beverage cans 1 are often bought by various manufacturers and filled for different reasons with, for example, a hot substance.
Dependent thereon, a vacuum which results from cooling liquid contents, .can: act against the spring tension, which is why a suitable closure from advantageous materials can act against an initial force of the tear-open devica. This force can be reduced i~ the first, upper closure 3 acts conically against the lid opening 6 and remains connected with lid 2 after the first opening.
Taking this solution into consideration, the ~ollowing procedure results: The tear-open device is turned upward and separates, since an auxiliary closure ~rom the next closing device is connected wlth the tear-open device 30: only after the tear-open device o~ that can is turned in the opposite direction..
: The d:rawings show one of the various feasible : beverage cans, and is not intended to exclude other e~bodiments of t~e structure of the lower closure. In this 3 5 ca~e, for example, it is recommended to turn the ring upward. The invention also includes other conceivable ....
