The same parts are given the same reference symbols in all figures designated.

Figure 1 shows a first embodiment of the invention. An annular groove 1 is located at a given point on the edge of the opening A. Evenly distributed, several protruding ribs 2 are provided on the edge of the stepped part next to the groove 1. The cap B has an outer wall and a relatively wide upper end bank. Legs 4 go down from several spatially distributed points on the inside of this end bank, each of which has a projection $, which runs close to the lowermost end of leg 4- and can engage in the annular groove Λ of opening A of the bottle. Each leg 4- has a triangular rib 5 formed on its inside, the tip of which lies on the upper inner part of the leg 4- and is widened from the tip downwards. A cut is formed at the lower end portion of the outer wall of the cap portion B which receives the upper end of an inner cap portion which will be described later. In this first exemplary embodiment, the leg 4- engages on its inside against the beveled rib 5, depending on the requirements

U 09821/0354

the leg 4 can be curved and have a beveled edge instead of the rib 5. A seal C is in the form of a disc and is located between the opening A of the bottle and the inner cap portion D.

The inner cap portion D has a tubular outer wall with a diameter such that this wall can be snugly received in the recess at the upper end of the outer wall of the cap portion B. The inner cap part D has on the inside an inner tubular part 7 »which engages the opening A of the bottle. The tubular inner part 7 is coupled together at its lowermost ends with the tubular outer wall 6 by a coupling part 8 to form a whole. The inner part 7 is arranged at a distance from the outer wall 6 which is sufficient to accommodate both the legs 4 and a push button. The tubular inner part 7 has a plurality of openings 9 at certain points which correspond to the projections 3 of the legs 4 and each of which serves to receive a projection 3. The inner part 7 has a disk-shaped upper part. A cylindrical hollow member 1o protrudes upright from this central part. The inner part 7 has at the lower end of its inner wall a plurality of ribs 11 for engaging the ribs 2 of the opening A of the bottle _β

A push button E has a tubular lower part of large diameter and a tubular upper part smaller diameter, which are formed on the outer edge of this button. This tubular lower part of the button E has an inner diameter that is suitable for mounting on the inner part 7 of the inner cap part D as well as for vertical sliding on the tubular inner part 7 is sufficient. Furthermore, a tubular hollow strut 12 extends from the central part the inside of the top of the button Ξ

409821/0354

below, which has an inner diameter that is suitable for receiving a hollow cylinder 1o of the inner cap part D. sufficient. A spring is wrapped around the strut 12.

In this first embodiment a special one becomes outer cap part D for receiving both inner cap part D and engaging cap part B. prepared, as shown in FIGS. 2A and 2B. The outer Cap part F has an opening 16 which extends into the upper part is formed and only the head of the upper tubular part of the push button E emerge through this opening leaves.

The first embodiment of the cap according to the invention is manufactured in the following manner; As FIGS. 21 and 2B show, the lower end of the engaging cap part B is first inserted into the space between the tubular inner part 7 and the tubular outer wall 6 of the inner cap part D until the engaging cap part B is in the inner cap part D. is in its place. The Yorsprünge be concurrently herewith 5 of the legs 4 of the cap part B by the entspreaaenaen openings 9 of the tubular inner portion 7 OCE inner cap D -from the outside of these openings forth used _s so that they naah of these openings from the inside out occur ₀ Thereafter, the pushbutton E from above applied to the tubular inner part 7 »Here the hollow cylinder 1o is inserted into the hollow strut 12 of the push button E and a spring is also placed around it the inner cap part D can be fitted and anchored, whereby a whole Zu ·.? Summary of these parts in such a way that the head of the push button-s E through the opening 16 of the

409821 / 03S4

Outer cap texls F is exposed. Furthermore, the seal C is on the lower end of the upper part of the inner part 7 of the inner cap part D. In this way the cap is made as a whole.

When in use, the push button B, which is indicated by the Opening 16 of the outer cap part F is exposed, according to pressed down, as can be seen from Figures 2A and 2B. The push button then moves progressively on the outer edge wall of the inner part 7 of the inner Part of the cap D downwards while it is pressing on the spring 13. During this downward sliding movement of the push button E, the lower tubular one engages Part that forms part of the outer edge wall of the snap- fes E forms progressively to the beveled ribs 5 the leg 4- of the cap part B. Accordingly, the Leg 4 pushed progressively outward by the push button E, increasing the distance between each of the opposite Leg 4- is enlarged. The protrusions

3 j which are at the lowest ends of the opposite Legs 4 are located, are thus possibly completely withdrawn from the annular groove 1 of the opening A of the bottle. As a result, the blocking condition that existed between the cap and the bottle opening up to that point is canceled. The cap can now easily be removed from the bottle opening be removed. With the release of the pressure on pushbutton B from there, this is activated by the Return to its original position by force of the spring 13.

If the removed cap is to be attached to the opening A of the bottle, only the opening A has to be inserted into the cavity the cap must be inserted firmly. Because the thighs

4 are elastic, they automatically become wider in relation to each other »The opening Ä of the bottle is thus

-7-409821 / 0354

easily received in the cavity of the cap. For this is brought the opening A into a given position in the tubular inner part 7 of the inner cap part D. With it obtain the legs 4 their initial positions again, so that the projections 3 »which are at the" lowest ends, be reinserted into the groove 1, which goes around the opening A of the bottle. The attachment is thus ended.

The second embodiment of the invention includes a mechanism which operates so that when the push button is pressed when removing the cap from the opening part of the bottle, the blocking state is released and at the same time the cap as a whole lifts itself by reaction and thus a problem-free removal of the cap results.

As shown in FIGS. 3 * 4A and 4B, this embodiment contains as well as the first the combination of an opening part A of a bottle with an annular one Groove 1, which is formed around the bottle neck, an engaging cap part B, which engages the opening A, a gasket C, an inner cap portion D, a push button E and an outer cap portion F. Under For these files it is only the seal G that is one of the Parts of the first example have a different shape. The other parts are exactly the same as the first one ■ General management example.

The seal G in the first embodiment has the shape of a disc. In the second example, however, the seal G is an elongated tube 14 which extends from the central part emerges upright »At the middle part of the pipe 14 there is a flange 15 »which prevents it accidentally separates from the inner cap part D. These develop-

-8- 409821/0354

speaking parts are assembled together as a combination, as shown in Figures 4-A and 4-B. Something the Requiring attention in the second embodiment is the relationship between the gasket C, the inner cap part D and the push button E. In particular, the tube 14- of the seal C goes through the upper part of the inner cap part D through so that it can be inserted into a hollow cylinder 1o of this cap part, and goes over the open top of the hollow cylinder 1o out.

When using the second embodiment, the Push button E pressed down as shown in Figure 4-B. ■ Then, as in the first example, the push button E is progressively on the edge of the tubular inner part 7 of the inner Cap part D pressed down while the spring 15 is being pressed. During this downward movement of the Push button E engages the tubular lower part of the push button E on the engaging cap part B. Through this the legs 4 · go into their corresponding positions when they progressively follow by the push button E. printed outside. Accordingly, the projections occur 3 » which are located at the lowermost ends of the legs 4-, out of the groove 1 of the bottle opening and thus lift the lock between the cap and the opening A.

In the first example, if you continue to press the push button, its upper part directly pushes the hollow cylinder Λ ο of the inner cap part D downwards. Thus, if the user presses the push button with one finger of his hand and at the same time tries to lift the outer edge of the outer cap part F with the other fingers of his hand, it is impossible for him to lift this outer cap part F because the force to lift by the force to Pressing the button Ξ is canceled. The protrusions

409821/0354

3 and the annular groove 1, which thus once locked out of their State detached from each other become inconvenient returned to the locked state when you stop pressing button E.

In the second embodiment, he lets the button When the pressure is applied, the upper part of the button touches the inner part of the cap D, but the upper part presses of the button E only on the elongated tube 14 of the Seal C. Therefore, if the user presses the button with a Finger presses and at the same time lifts the outer cap part F with the other fingers, the inner cap part can D, which is assembled with the outer cap part F to form a whole, together with the engaging cap part B slightly lifted from opening A of the bottle. Even if the pressure applied to button E ceases, the cap will not fit back onto opening A. The cap can thus be removed without difficulty.

The third embodiment, which the Figures 5 »6A and Figures 6B show is of the type of mechanism showing the same function and how the second example works. One and only . The difference from the second example is that instead of the spring 13 there is a spring 18 within the elongated tube 17 of the seal C is used. At the Pressing the push button E causes the seal G to be activated immediately pressed over the spring 18.

As mentioned, the push button cap works according to the invention described in connection with the three examples has been so that just by pressing the push button the legs with a protrusion at their lowest end, which engage in the ring groove of the bottle opening let them separate from each other, so that they. loosen their fastening, whereby the cap can be adopted as a whole.

"■ -1ο-409821/0354

On the other hand, the removed cap can only pass through. Insert, of the opening part of the bottle into the cavity of the Cap will be attached automatically. The cap according to the invention is thus simple and easy to use use. In addition, the projections of the legs are used to engage in the annular groove of the opening part and thus this engagement and anchoring of the Cap done without difficulty, so that there is no fear that the cap will come off by itself. Because of the ribs for attachment between the bottle opening and the cap provides the further convenience that the Attaching the cap to a container of a different type or shape, for example is possible.

In the first two examples, the spring 13 is in the above enclosed snap fastener part so that one end of this spring touches the top of the snap fastener part and the other end is supported by the upper wall of the inner tube part 7 of the inner cap part D, such as Figures 2A and 2B can be seen. In the third example, however, the other end of the spring 18 of the inner lower end edge of the elongated tube 17 supported.

An example has been described in which a spring is provided. Of course, the spring is not an essential part of the invention and the use This spring only serves to smoothly return the pressed pushbutton to its original, non-pressed one Able to effect.
