Closure device for tubes

The invention relates to a closure device for tubes that cannot be lost and is easy to use.

Tubes are usually screwed through Cap closed, but this has the serious disadvantage that both hands are used to close the tube are necessary. In addition, caps are easily lost; so falls z. B. with toothpaste tubes the cap not infrequently into the drain of the washbasin.

There has been no lack of attempts to design captive closure devices for tubes, but the previously known embodiments have not been fully satisfactory and therefore have not been able to establish themselves in practice, either because they are too complicated or too expensive to manufacture or too inconvenient to use or the closure did not sufficiently meet the tightness requirements.

The aim of the invention is to provide a novel closure device in which these disadvantages are avoided are. It is therefore in a closure device for tubes and the like. Consisting of one on the tube screw-on, provided with an internal thread screw cap and movably mounted closure piece according to the invention, the closure piece mib, which essentially has the shape of a short cylinder

- 2 - 209849/0 279

provided a hole, the two openings on opposite sides Sides of the lateral surface are, and the closure piece in a recess of the screw cap between two end positions limited by stops rotatably mounted in such a way that the side parts the screw cap extend over the middle of the closure piece, in one of the two end positions one mouth of the bore is free and the other mouth with the central bore of the screw cap communicates, while in the other end position both mouths of the bore of corresponding Opposite surfaces of the screw cap are covered and thereby the opening of the inner bore of the screw cap of the cylindrical outer surface of the closure piece is covered.

It is useful if the bore in the cylindrical disk is parallel to a diameter of the cylindrical Closure piece, but is arranged laterally offset against it. The closure piece is advantageous on the side facing away from the central bore of the closure cap with a protruding Provided handle.

It is advantageous here if the cylinder disk is on the side facing away from the central bore of the closure cap is provided with two projecting parts is, which are dimensioned and arranged such that in each of the two end positions there is a projection is supported against an associated mating surface on the top of the screw cap.

In a preferred embodiment, the protruding handle piece and the two form as stops serving projections have a common, in the material

209849/0279 " ³ "

connected component, it is useful if the protruding component is connected to the cylindrical part of the screw cap in the material.

In some cases it is advantageous if the closure piece is in the vicinity of an opening of the bore, preferably on the cylinder jacket surface, has a protruding part, which in the closed state in a corresponding recess in the screw cap engages. It has been proven that the screw cap from one produce flexible material in such a way that the cylindrical closure piece from the outside by elastic Deformation of parts of the screw cap can be used in this. Both practical and aesthetic Embodiment results when the material of the cylinder is one of the material of the screw cap has a different color.

In the following the invention is in connection with the figures representing an embodiment are described; corresponding parts are in all Figures designated in the same way. It shows:

Fig. 1 in longitudinal section a closure cap according to the invention on an enlarged scale in the open Position;

FIG. 2 shows a plan view of the closure cap according to FIG. 1;

3 shows the closure cap of FIG. 1 in a closed position Position;

Fig. 4- a structural detail.

21243S1

The closure cap shown in the figures consists of a on the (not shown) Tube screwed screw 1 and a movably mounted therein closure member 2. The screw cap has a central, substantially cylindrical bore 3 »which is provided h with an internal thread, which exactly the external thread of the associated tube fits. The bore 3 has a central opening 5 on the side facing away from the tube, the diameter of which is smaller than the diameter of the bore 3. The side parts 6 of the screw cap 1 protrude slightly above the center of the closure piece upwards, so that it is well stored and secured against any falling out. The closure piece is inserted from above by applying slight pressure while at the same time expanding the corresponding edge zone of the screw cap.

The closure piece 2 has a bore 7j communicates in the position shown in Fig. 1, the bore 3 and thus the interior of the (not shown) Tube with the outside air, while in the position shown in FIG. 3, the cap is closed because both the mouth 7a of the bore 7 and the mouth 7b of the bore by corresponding counter-surfaces of the screw cap are covered and the opening 5 of the inner bore 3 of the screw cap from the cylindrical outer surface of the closure piece 2 is covered. Since the opening 5 adjacent parts of the flexible material existing screw cap resiliently against the corresponding

209849/0279

Apply the opposing surfaces of the closure piece, a good seal is achieved. The closure piece 2 is on the side facing away from the bore 3 of the closure cap is provided with a protruding handle 9, so that by light finger pressure the locking piece of the open to the locked position can be turned or vice versa.

Projections 10, which have radial end surfaces 11, adjoin the handle piece 9 on both sides. These end faces are arranged so that in each of the two in Pig. 1 and Fig. 3 drawn end positions of the closure piece each one of these end faces 11 against the upper end of the associated side part 6 supports. In a preferred embodiment, the screw cap consists of red, somewhat flexible Plastic and the screw cap together with the handle 9 and the projections 10 from one piece of white Plastic of greater hardness.

In the vicinity of the end faces 11, a corresponding latching device can be arranged in each case so that the closure piece engages in the closed position.

Fig. 4 shows on an enlarged scale such a locking device, in which a projection 11 of the one Component engages in a corresponding recess 12 of the other component.

Due to the special construction of the invention Locking device ensures that in the closed state also the one in the bore of the locking piece

located part of the tube contents cannot flow out and is kept practically airtight and thus protected from drying out

It has proven to be useful if the bore has the same diameter as the mouth of the screw cap, so that when the closure device is open at the transition point between the screw cap and the inserted Versohlußstüok no material jam occurs.

The embodiment according to the invention is characterized by the following advantages from

1. The Verschlußvorrielitirag is easy _t bedi®nen with one hand both for opening and for closing, "

2. The spanking device can also be used in the dark or by the blind without the risk of a Losing unscrewable parts.

3. The embodiment according to the invention has the peculiarity on that the connection between the inside of the tube and the outside of the tube in the closed state is closed by two seals. The inside of the tube is initially in the closed state sealed in that the somewhat flexible edge zones of the central screw cap opening are resilient apply against the movable closure piece, so that the contents of the tube emerge at this Place is prevented. In addition, both mouths of the bore are through corresponding mating surfaces of the Screw cap covered.

209849/027 9

In the open state, the tube contents exit at the top of the closure device in the immediate vicinity of its axis, so that the tube contents do not have any great resistance when flowing out
has to be overcome and therefore the outflow occurs steadily even with slight pressure on the tube, namely essentially in the longitudinal direction of the tube.
