Abstract

The present invention relates to screw caps and to containers having removal openings for fluids and the screw caps thereof, wherein the screw caps have a device for the fastening thereof on a carrier surface.

Description

Cap with holding device

The invention relates to caps of containers for liquids, which are inhibited in their fluidity, the cap can be mounted on a support surface.

Containers for liquids that are inhibited in their fluidity, for example, tubes.

A tube is known to consist of a tube body and a closure. A tube body is an elongated, solid, but mouldable container containing soft substances such as e.g. Cream or toothpaste, but also food or technical masses may contain. The round or oval shell is usually made of plastic or sheet metal. The removal of the contents is an opening with a closure at one end. This usually round opening sits in the middle of the so-called. Tube shoulder and is closed by a so-called. Cap, which may be made of plastic or metal, for example.

The content of the tube is generally made of soft substances, preferably of thixotropic masses.

When using tubes, the continuous screwing and unscrewing of the tubes is annoying, is therefore often forgotten and leads to dried-up tubes. In addition, upright tubes make a visually better impression.

There are numerous solutions to improve the opening and closing of tubes and also the upright standing of cream containers.

For example, standing piston bottles are commercially available, in which the cream is conveyed via a piston upwards and out of the container. However, this type of packaging is very expensive and therefore has little commercial significance. Also known are membrane-containing Stehtuben. These closures have long been known in the field of shower products as well as in the food industry (honey and ketchup). Especially for toothpaste, these packages are too expensive and not very hygienic, because despite the membrane often leftovers in the supplied stand remain.

There are also known as studs tube caps are known in which, however, the sealing and closing the tube is insufficiently solved.

DE 196 39 124 A1 describes a tube closure with a cylindrical lower part designed as a tube shoulder, which has an outlet opening on its front side, and a closure cap which can be applied to the lower part and which is applied to the lower part

State closes the outlet opening, wherein the lower part has recesses on its circumference, which extend over about a quarter of the circumference and extend to the axis of the lower part at an angle of 85 to 60 degrees, and wherein the closure cap inside on its circumference protrusions ("locking knobs "), which engage in placed on the lower part cap in the wells.

In column 2, lines 16 to 33 of the document, a guide of the tube is described in the tube closure. The guide is achieved by the slope of the Rastnuts (bayonet lock).

In DE 21 61 237 A1 a device for holding tubes and plastic bottles is described, in which both are equipped with an externally conically shaped, internally provided with a Durchläse mouthpiece and rest vertically in a holder made inside sucking mouthpiece cone holder, wherein the mouthpiece with internal thread screwed on the threaded socket mounted in the base of the closure and thus the passage in the mouthpiece is blocked. DE 199 24 730 A1 describes a bayonet-type tube closure.

In DE 74 09 723 U1 a wall mount for tubes is described.

DE 10 2006 035 701 A1 discloses a tube closure with a self-sealing closure cap which has locking cams or a sealing seat with locking lugs.

Object of the present invention is to provide an example upright container with removal opening for liquids with a cap, which allows to remove the container at any time without opening process and just as easy to spend after use in cap, and this without the cap falls over or slip. The removal and the resetting of the container should be possible in one-handed operation.

It has been found closure caps for containers with removal opening for liquids, characterized in that the closure cap has a fastening device for the support surface.

A preferred embodiment of the present invention is characterized in that the outside of the bottom of the closure cap with one or more suction cups as a fastening device, preferably a suction cup, is equipped, which are fixed by pressing on the support surface.

A preferred embodiment of the present invention is characterized in that the outside of the bottom of the cap is provided with an adhesive film as a fastening device. Commercially available adhesive films or magnets can be used here. A preferred embodiment of the present invention is characterized in that the outside of the bottom of the cap is equipped with a Velcro tape as a fastening device. It can be used here commercial Velcro.

A preferred embodiment of the present invention is characterized in that the outside of the bottom of the closure cap is equipped with a locking nubs as a fastening device which engages in a recess on the support surface.

A preferred embodiment of the present invention is characterized in that the outside of the bottom of the closure cap is equipped with a flexible or elastically movable holding plate as a fastening device. Such retaining plates are described for example in DE 39 26 969 A1. The holding plate has an inner side, which faces the outside of the bottom of the closure cap, and an outer side, with which the holding plate rests in the standby state on a sufficiently smooth support surface and is freely displaceable on this in all directions.

The holding plate is punctiform or expands in terms of area with a region of its inner side on the outside of the bottom of the closure cap, wherein the surface attachment may also consist of a plurality of closely adjacent attachment points. The attachment of the holding plate on the outside of the bottom of the

Closure cap is preferably point-symmetrical about the center of the retaining plate and the center of the outside of the bottom of the cap, so that an equally wide edge region is present on all sides, in which the retaining plate is not connected to the outside of the bottom of the cap. The area of the holding plate fixedly connected to the outside of the bottom of the closure cap is comparatively flat and stiff and the edge regions of the holding plate protruding laterally from the latter are flexibly flexible or elastically movable.

In a preferred embodiment, the surface of the edge region of the retaining plate is comparatively large in comparison to the fastening surface, via which the retaining plate is connected to the outside of the bottom of the closure cap. The width of the flexible, freely movable edge region around the mounting surface of the inner surface of the retaining plate may vary depending on the size of the surface of the bottom of the closure cap and / or the size of the container to be closed by the closure cap. Preferably, the edge region has a width of 0.8 mm to 5.0 cm.

The retaining plate may be sheet-like, for example made of rubber or plastic. The retaining plate or its flexible, elastically-movable edge region may have a thickness of 0.5 to 3 mm. The thickness of the retaining plate can decrease towards its outer edge.

In its simplest embodiment, the retaining plate is formed as a one-piece web of material extending over the edge regions and the fastening surface, which is connected to its surface on the inside of the retaining plate with the outside of the bottom of the closure cap. However, the holding plate may also be formed in several pieces, for example, by using a different material for the flexible edge region, preferably a softer rubber, than for the region of its attachment surface. In these embodiments, use may be made of the possibility that the closure cap and the attachment surface of the holding plate are made of the same material. Preferably, the holding plate is circular. But it can also have a different geometric shape, for example, be oval, three-, four- or polygonal. In particularly preferred embodiments, the holding plate has the same contour as the bottom of the closure cap.

In preferred embodiments, the retaining plate is not larger than the bottom of the cap. This means that the edge of the retaining plate does not protrude beyond the edge of the bottom of the cap. Consequently, the contour of the bottom of the closure cap and the contour of the holding plate is congruent or the contour of the holding plate is smaller than the contour of the bottom of the closure cap with the same shape.

In the standby position, the retaining plate is located both with the outside of the holding plate fastened in the region of its inner surface on the outside of the bottom of the cap and with the laterally outwardly thereof

Mounting surface extending, otherwise not fixed movable edge projection or edge region on the sufficiently smooth support surface and is on all sides Slidable. In the standby position there is virtually no biasing negative pressure, so that the cap can be lifted by slow and gentle lifting of the support surface without the holding plate has an adhesive effect, since the edge region rests only with its own weight on the surface of the support surface.

Only at the moment of the occurrence of a withdrawal force, ie when pulling up from the support surface or when a tilting force occurs, does the pressure forming in the support plane cause a comparatively firm application of the flexible, elastically movable edge region of the retaining plate. In this way, a holding of the holding plate and the cap attached thereto is ensured on the support surface, so that a plug in the cap container can be removed. The cap remains adhered to the support surface without tipping over. The sticking or holding effect is all the more stronger, the faster or pulse-like the pull-off force is exerted, so the faster or more jerky a container of the cap is removed.

Even with claimed adhesive force, the holding plate is displaced laterally. However, the force required for a laterally displacement of the retaining plate under the applied adhesive force is greater than unclaimed adhesive force, so that a significant slipping or displacement of the closure cap when the container is removed as intended is largely avoided. The lateral displaceability, even with claimed holding force, depends on the hardness of the retaining plate or the edge regions of the retaining plate. In a lateral displacement, the flexible edge projection of the retaining plate adapts depending on the nature of its material to any unevenness of the pad, so that the lateral displacement is greater with a harder rubber than with a softer rubber.

A further preferred embodiment of the present invention is characterized in that the attachment is mounted on an overcap pushed over the closure cap.

The closure caps according to the invention can preferably be used for closing containers which contain a liquid which, owing to its physical properties (thixotropy), has low flowability or whose flowability is inhibited, for example, by a membrane. For example, tubes, bottles or ink sticks, preferably tubes, may be mentioned here. Thus, the statements made below for tubes apply equally to bottles, ink pens and other containers.

By attaching the cap of a tube body on a

Support surface, such as a work surface, manages in a simple way, the rapid absorption and deposition of the tube body in the application. By the Fixing a slipping and / or toppling of the cap is excluded and allows one-handed operation. A locking of the cap is not required.

The base of the cap can take various forms. In the context of the present invention, it is preferred that the base area of the closure cap is circular or elliptical.

In the context of the present invention, the fastening of the closure cap of a tube body takes place via the outside of the closure cap. The attachment can be permanent, but also solvable.

In the context of the present invention, the following embodiments of the closure cap and the tube body are preferred:

According to a preferred embodiment of the invention, the outlet of the tube body is formed into a sealing cone, which engages in a sealing seat at the bottom of the closure cap, and its connection to the tube is designed as a centering, wherein in the cap movably mounted cap locking lugs are mounted when closing engage the tube in a groove above the sealing cone at the tube shoulder, that is between the tube shoulder and sealing cone.

The sealing seat in the middle of the bottom of the cap can be designed as a cylinder, on which the sealing cone is seated. The sealing seat may also be formed as a hemisphere, as a mandrel, as a cone or pyramid, which engage in the tube opening and thereby seal the tube contents. Alternatively, the sealing seat can also comprise a seal formed as a hemisphere, mandrel, cone or pyramid. The sealing seat generally has a height of 0.5 to 10 mm, preferably 2 to 5 mm, and engages in the outlet in the open state of the tube and seals the tube against escaping product and from outside penetrating dirt. In a particularly preferred embodiment, the gasket forming a sealing seat has a groove-forming undercut, so that the gasket engages in this after its passage through a hole in the bottom of the cap and thus enters into a positive connection with the cap. Preferably, the seal has an undercut, which forms a circumferential groove. However, it is also possible embodiments of the seal with two opposing undercuts or three undercuts that form an equilateral triangle.

The embodiments with seals which have an undercut for the positive connection with the cap, have the advantage that can be dispensed with gluing or welding the fastening device, in particular a suction cup or a holding plate, with the bottom of the cap. So seal and suction cup or holding plate can be made in one piece from the same material. But it is also possible to produce the seal on the one hand and the suction cup or the holding plate on the other hand made of different materials and, for example, by gluing, welding or two-component injection molding together.

The tube body according to the invention with a cap allows, surprisingly, to remove the tube at any time without opening operation and just as easy to spend after use back into the stand, and this without drying the tube and without large additional costs. By pressing the tube into the cap, the locking lugs movably connected by means of film hinges are moved from their stable end position into another stable end position in the closed position and engage the tube body in the groove between the outlet of the tube body and the tube shoulder that the tube is stably sealed for transport, for example. The opening of the tube is carried out accordingly by pulling the tube body out of the cap, whereby the movably connected via film hinges locking cap and sealing seat locking lugs are tilted from the closed stable end position in the open stable end position and release the tube body.

According to another preferred embodiment, locking cams are attached to the upper edge of the recess and at least one latching groove is provided at the outlet of the tube body,

- In the center of the bottom of the cap, a sealing seat is attached, which seals the outlet of the tube body, and

- Wherein a guide for centering the tube body is mounted on the tube shoulder during insertion into the cap, e so-called centering collar.

In a preferred embodiment of the aforementioned embodiment, the at least one locking groove is attached to the centering collar.

Also, the tube body according to the invention with locking groove and cap, which has locking cams, surprisingly allows to remove the tube at any time without opening process and just as easy to spend after use back into the stand, and this without drying the tube and without large additional costs. By turning the cap, the locking cams snap into the locking groove, so that the tube is stably sealed, for example, for transport.

Both variants are ideal for the packaging of thixotropic materials.

In the context of the present invention, the guide for centering the tube body may preferably be attached to the tube shoulder. A particular embodiment of the present invention relates to closure caps of tube bodies, wherein the base of the closure cap is formed into a closed support surface and the opposite side of the closure cap to a recess for insertion of the tube body, wherein at the upper edge of the recess locking cams are formed and movable via film hinges has locking lugs connected to the cap and a sealing seat arranged at the bottom of the cap. In this embodiment, the locking lugs movably connected by means of film hinges with closure cap and sealing seat are moved by pressing the tube in the cap from its stable end position in the open position to another stable end position in the closed position and engage the tube body in the groove between the outlet of the tube body and tube shoulder a, so that the tube is stably sealed. By subsequently rotating the cap, the locking cams snap into the locking groove, so that the tube is sealed particularly stable, for example, for transport.

In order to be able to open the tube, the closure must be turned so that the locking cams are guided out of the latching groove. The opening of the tube is then carried out accordingly by pulling the tube body out of the closure cap, whereby the movably connected via film hinges locking cap and sealing seat locking lugs are tilted from the closed stable end position in the open stable end position and release the tube body.

Thixotropic compositions in the context of the present invention are "non-Newtonian liquids" which reduce the viscosity at a constant shear. After exposure to the shear stress, the initial viscosity is rebuilt.

Both versions of the uprights can be designed as a cylinder or, for better stability, as a truncated cone, the basic surface may be circular or elliptical, so that the tube can be safely upright in any case.

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

The tube cap with the individual elements can generally be produced in a conventional injection molding process.

The production of the tube body with the locking groove can also be carried out in a manner known per se, e.g. by injection molding, done.
