Description

Tube closure {Tube closure}

The present invention relates to a tube body having a closure cap and a method of using a tube body having a closure cap for storing and using thixotropic compounds.

As is known, the tube includes a tube body and a closure. The tube body is an elongate solid moldable container that may contain soft substances such as, for example, creams or toothpastes, foodstuffs or technical compounds. Round or oval casings are generally made of plastic or thin metal. An opening with a closure at one end serves to remove the contents. This round opening is located at the center of the "tube shoulder" and is closed by a "cap" which can be formed, for example, of plastic or metal.

The contents of the tube generally comprise soft materials, preferably thixotropic compounds.

While using tubes, it is cumbersome to keep closing them by turning them over and over, often forgetting and completely drying out of the tubes. In addition, the upright tubes give a better visual impression.

Many solutions have been proposed to improve the opening and closing of tubes and the uprightness of cream containers.

For example, flat bottom flasks in which the cream is moved to the top and the outside of the vessel by a piston are commercially available. However, since this type of container is very expensive, it is of little commercial importance.

Upright tubes containing membrane closures are also known. Such closures have long been known for wooden supplies and foodstuffs (honey and ketchup). In particular, for toothpaste, these containers are too expensive and, despite the membrane, are not hygienic because product residues often remain supplied to the container.

Tube closure caps are also known which are designed as pedestals, but the sealing and sealing of the tube is not sufficiently done in such tube closure caps.

The publication DE 196 39 124 A1 has a cylindrical lower part 1 which is designed as a tube shoulder and has an outlet opening 2 on one side, and which can be fitted to the cylindrical lower part 1, and in which the discharge opening 2 is fitted. A tube closure comprising a closure cap (3) closing the cylinder) is described, wherein the cylindrical bottom (1) extends over about a quarter of the outer circumference on the outer periphery, and the shaft (5) of the cylindrical bottom (1) With recesses 4 rotating at an angle of from 85 ° to 60 °, preferably from 80 ° to 70 °, the closure cap 3 has a closure cap 3 located in the cylindrical lower part 1 With protrusions 6 (latching studs) that engage with the recesses 4 when in the outer circumference.

Tube guidance into the tube closure is described in column 2, lines 16 to 33 of this publication. This guidance is made by the inclination of the latching groove (bayonet-type closure).

In addition, the publication DE 21 61 237 A1 has a mouthpiece which is provided internally with a passageway and is conical towards the outside and is manufactured on the inside to move towards the mouthpiece cone. A device for supporting tubes and plastic bottles located vertically in a shell) is described, wherein the mouthpiece is turned by an internal thread of a threaded connection piece that is tightened at the base of the closure, thereby providing a passage in the mouthpiece. Is blocked.

Publication DE 199 24 730 A1 describes a bayonet-type tube closure.

The publication DE 74 09 723 U1 describes a wall mount for a tube.

It is an object of the present invention to provide a tube standing upright in a pedestal, wherein the tube can be removed at any time without a predetermined opening operation, and after use, the tube can be attached to the pedestal in a similar simple manner. It is possible to provide a tube that can perform this process without drying the contents of the tube without additional cost. In addition, the tube of this type is sealed, for example, to be stable during transport.

According to the invention, the bottom face of the closure cap is circular or oval, the bottom face is designed to form a closed upright face, and the opposite face of the closure cap is designed to form a recess for the insertion of the tube body. As the tube body, latching cams, or sealing cones with locking projections, are arranged on the upper edge of the recess, and correspondingly, at least one latching groove is arranged on the outlet of the tube body, A closure is arranged in the center of the bottom, the closure sealing the outlet of the tube body, and having a guide for adjusting the tube body to be centered during insertion into the closure cap. A tube body with a cap is provided.

In contrast to the tube closure known from publication DE 196 39 124 A1, according to the invention, the tube body is guided into the closure cap by guide elements in the interior (the recess) of the closure cap.

This type of guide according to the invention has the advantage that the tube is engaged in such a way that it is centered at the top of the bottom of the withdrawal section, while at the same time the tube does not need to be sealed.

Known bayonet-type closures have, in particular, two substantial disadvantages which can be avoided by the closure according to the invention:

For known bayonet-type closures, due to the design, when the tube is placed, there is an approximate 50% chance that the latching groove is in the designated recess to seal the tube and stand in a stable manner. According to the invention, this position can always be made. Known bayonet-type closures always require two-handed operation for mounting the closures, but the present invention allows for the mounting of the closure with only one handed operation. Two-handed operation has no advantages over conventional screwing of the tube, while one-handed operation substantially facilitates use.

For example, the invention may be practiced in the following preferred embodiments:

According to a first preferred embodiment (Example A, FIG. 1), latching cams are arranged on the upper edge of the recess, correspondingly at least one latching groove is arranged on the outlet of the tube body, and a closure cap A sealing seat is arranged in the center of the bottom of the seal sheet, the sealing sheet seals the outlet of the tube body, and a guide for adjusting the tube body to be centered during insertion into the closure cap on the tube shoulder portion. Are arranged in.

The sealing sheet in the center of the bottom of the closure cap may have a shape designed as a hemisphere, spike, cone or pyramid. The sealing sheet generally has a height of 0.5 to 10 mm, preferably 2 to 5 mm, in the open state of the tube, meshes with the outlet of the tube, and seals the tube to prevent the product from coming out and dust from entering the outside. do.

According to the invention, the tube body with the closure cap (Example A) can be removed at any time without any opening action, and after use it can be attached to the pedestal in a similar simple manner, with additional costs This allows this process to be carried out without drying the contents of the tube. By rotation of the closure cap, the latching cams are latched into the latching groove so that the tube is closed to be stable, for example when transporting.

According to another preferred embodiment of the invention (Example B, Figure 3), the outlet of the tube body is designed to form a sealing cone, the sealing cone engages in the sealing sheet on the bottom of the closure cap, and the closure cap is centering Connected to the tube body by a centering aid, the cap-locking protrusions are elastically installed on the bottom of the closure cap, and latched into the groove of the upper part of the sealing cone on the tube shoulder while the tube body is closed. do.

The sealing sheet on the bottom of the closure cap may be designed as a cylinder in which the sealing cone is installed. Such a sealing sheet can also be designed as a hemisphere, spike, cone or pyramid that seals the tube contents by engaging the tube opening.

The tube body with a closure cap according to the invention corresponding to Example B, with Example A, the tube can be removed at any time without opening action, and after use it can be attached to the pedestal in a similar simple manner. This allows this process to be carried out without drying the contents of the tube, at no additional cost. By pressing the tube into the closure cap, the locking projections movably connected to the closure cap and sealing sheet via film hinges move from the stable end position of the open position to another stable end position of the closed position. And latched in a latching groove on the tube body, so that the tube is sealed to be stable, for example, during transportation.

Correspondingly, the tube is opened by pulling the tube body away from the closure cap, with the locking projections movably connected via the thin film hinges to the closure cap and the sealing sheet, from the closed stable end position. By tilting to the distal position, the tube body is opened.

All of the above embodiments are well suited for containing thixotropic compounds.

Within the scope of the present invention, a guide for adjusting the center of the tube body is preferably arranged on the tube shoulder portion.

Thixotropic compounds within the scope of the present invention are "non-Newtonian fluids" whose viscosity decreases under constant shear stress. When the application of shear stress ceases, the initial viscosity builds up again.

The pedestal cap of the two embodiments is designed such that the tube is cylindrical or shaped like a truncated cone or rounded or elliptical in shape to enhance stability so that the tube is always firmly upright.

The size of the base surface of the tube body corresponds to the size of the tube body. The tube cap, in a preferred embodiment in the form of a cone, has a lower diameter of 40 to 80 mm tapering upwardly to a tube diameter of approximately 20 to 50 mm.

The height of the tube cap is generally in the range of 20 to 50 mm.

Tube caps with respective elements can generally be manufactured by conventional injection molding processes.

Similarly, the production of a tube body with a latching groove can be carried out in a known manner, for example by injection molding.
