Abstract

A tiltable container has a cylindrical container body with a primary support surface and a secondary support surface. The secondary support surface extends at an acute angle to the primary support surface. The primary support surface extends over more than half a cross-sectional area defined by the diameter of the container body, wherein the primary support surface projects by at least 5% of the diameter past a vertical center plane of the container body.

Description

TILTABLE CONTAINER
Background of the Invention The present invention relates to a tiltable container having a primary support surface which extends over more than half of the bottom side of the container and a secondary support surface extending at an oblique angle to the primary support surface. Such containers are especially used for ceramic powders in the dental field.
Tiltable containers have been suggested in which the containers have two different support positions. One position is provided by a primary support surface and is considered the storage position, and the other position is defined by a secondary support surface and is used as the removal position for taking material from the container.
Perfume flasks are also known which have bottom surfaces positioned at an angle to one another. However, the size of these surfaces is such that only one surface can be used as a support surface while the other bottom surface, extending at an angle to the support surface, is provided only for appearance reasons. An example of such perfume flasks is disclosed in German Gebrauchsmuster 92 05 862.
Furthermore, tiltable containers have been suggested in which a pivot mechanism for the container is provided so that the container, for emptying, can be tilted to remove the flowable material which may be a liquid. Such containers provide for a continuous adjustment of the tilting angle. A disadvantage of such containers is that the pivot mechanism requires considerable expenditure.
It is therefore an object of the present invention to provide a tiltable container of the aforementioned kind which is especially suitable for use in the dental field, can be easily manipulated and inexpensively manufactured.
Summary of the Invention According to an advantageous embodiment of the invention, the inventive tiltable container can be positioned on the primary support surface as well as on the secondary support surface, and in both positions the container is in a stable support position.
Especially when using such tiltable containers for flowable materials, such as ceramic powders, the inventive design provides for a stable support on the secondary support surface. The dental technician can thus remove the required amount of ceramic powder with a suitable removal tool in an ergonomic manner without the risk of contacting the container neck with the removal tool and losing ceramic powder. For example, when a flat spatula is used as a removal tool, a certain slanted position of the spatula is required in order to be able to remove the ceramic powder. The spatula must be at least so flat that the repose angle of the ceramic powder is not surpassed.
With commercially available containers without a secondary support surface such manipulation is relatively difficult because it is almost inevitable that the spatula contacts the inner side of the neck of the container resulting in loss of ceramic powder.
In order to further improve and facilitate manipulation, in some instances the ceramic powder for removal is filled into a flat dish so that it is easily removable. However, this requires additional steps since after use the excess material of ceramic powder must be returned into the container. This can also result in further loss of ceramic material. Also, the ceramic powder in the flat disk is relatively unprotected. For example, a light air current can result in the loss of ceramic powder and may also lead to contamination of the surroundings.
Inventively, it is especially advantageous that the manipulation can be performed with conventional removal tools and is thus very simple. The dental technician can rest the tiltable container, when it is still completely filled, on the primary support surface in order to remove material therefrom. When the degree of filling is, for example, less than 90%, it is suggested to then employ the secondary support surface and to use the container in the tilted position. Due to its own weight, the container, with the added weight of the ceramic powder contained therein, will securely rest on the secondary support surface. In this state, a flat spatula can be easily inserted into the container, and with the spatula or any other suitable removal tool ceramic powder can be removed, without contacting or impacting the container neck, even while maintaining the required repose angle that requires a certain slanted position of the removal tool.
It is understood that the precise dimensions of the inventive tiltable container can vary in wide ranges depending on the desired use. In any case, it is preferred to employ a tiltable container having the shape of a relatively flat and wide flask or bottle. The tilting safety can be increased by increasing the container height.
However, the removal action is much simpler for tiltable containers having a reduced height.
In addition to these advantages, the inventive container also protects the ceramic powder during removal against air currents.
Employing an auxiliary dish, which complicates handling and increases the risk of loss of material, can thus be avoided.
Since the primary support surface extends substantially past the vertical center plane of the container, the tiltable container when supported on the primary support surface is in a stable position.
The secondary support surface, when viewing the container in a vertical projection, is thus correspondingly smaller than the primary support surface since the primary support surface projects the vertical center plane of the container.
When the secondary support surface extends at an angle of 45° to the primary support surface, the length of the secondary support surface as the hypotenuse of a isosceles triangle corresponds to ,r2 times the length of one of the identical sides of the triangle, i.e., the length of the vertical projection of the secondary support surface onto a supporting surface (table top etc).
Depending on the arrangement of the connecting line between the primary support surface and the secondary support surface, despite the fact that the primary support surface extends past the vertical center plane of the container, the length of the secondary support surface and the length of the primary support surface can be identical or substantially identical.
It is understood that the angle between the secondary and primary support surfaces can be adjusted in wide ranges depending on the required use. For taller containers it may be advantageous to select the slant to have a smaller angle so that the secondary support surface ends substantially below half the container height.
For especially flat containers, it is, on the other hand, suggested to increase the angle, especially in orderto provide a pronounced tilted position. With containers having a height/diameter ratio of substantially less than 1, the secondary support surface can end substantially above half the container height. While inventively a round neck container is preferred, since it is easier to close, it is understood that, if desired, it is also possible to provide any other suitable container neck. The container opening is inventively provided always opposed to the primary support surface.
Inventively, it is preferred that the container has a bottle shaped design. The resulting tapering at the top increases the stability of the container because the center of gravity by this measure is moved downwardly.
In an advantageous embodiment of the inventive container, it is suggested that the container is provided with a safety seal.
Preferably, a lid or cover with a projecting pull lever is provided whereby the upward movement of the pull lever results in a destruction of the safety seal provided with a designated breaking point or line. The lid or cover is thus opened by destruction of the safety seal. Such safety seals are known in the prior art and do not require any further detailed description.
The material of which the container is made can be selected as desired. For example, the container may be comprised of injection-molded polypropylene. Transparency of the material can be selected as desired. For example, black coloring may be provided when the material contained in the container must be protected from light. By providing a transparent material, it is possible to monitor the filling level of the material in the container.
Brief Description of the Drawings The object and advantages of the present invention will appear more clearly from the following specification in conjunction with the accompanying drawings, in which:
Fig. 1 shows a front view of an embodiment of the inventive tilting container;
Fig. 2 shows a side view of the tilting container of Fig.
1;
Fig. 3 shows a bottom view of the container according to claim 1.
Fig. 1 shows the inventive tiltable container 10 in a front view in a schematic representation. In order to facilitate the drawing, the corresponding lid has been omitted so that the design of the container neck 12 is clearly shown. The tiltable container 10 is substantially round and symmetrical to the container axis 16. It has a height 18 which is substantially identical to its diameter 20. The container neck 12 tapers so that the container body 22 bulges relative to the container neck 12.
Inventively, the tiltable container 10 is provided at its bottom side with a primary support surface 24 and a secondary support surface 26. As can be seen especially in Fig. 2, the secondary support surface 26 is positioned at an angle relative to the primary support surface 24. The angle is preferably 45°. In a manner known to a person skilled in the art, the bottom side of the container is slightly upwardly curved. This curved portion extends across the primary as well as the secondary support surfaces 24, 26.
Accordingly, contact to a table top or other supporting surface is a linear contact by substantially semicircular arcs of the projecting edges 28 of the primary support surface 24 and the secondary support surface 26. The depression 30 can be seen especially well in Fig. 2 and is indicated by a dashed line.
The transition between the primary and secondary support surfaces 24, 26 is formed by a connecting line 32 which is rounded by a small radius. As can be seen especially in Fig. 2, the primary support surface extends past the vertical center plane of the container to the right by a significant amount. The total length 34 of the primary support surtace is, for example, 65% of the container _g_ diameter 20 so that the projecting portion, i.e., the distance between the vertical center plane of the container and the connecting line 32 is, for example, 23% of the length of the primary support surface 24.
This projecting portion improves the tilting stability of the inventive container 10 when being positioned on the primary support surface 24.
Even though the length of the secondary support surface 26 in a projection onto the supporting surface (table top), when viewing the container in a position placed onto the primary support surface, according to the aforementioned embodiment is only 35% of the container diameter, the actual length 36 of the secondary support surface 26 is substantially greater. It is calculated to,~2 x 35%, i.e., substantially 50% of the container diameter. Accordingly, despite the projecting portion of the primary support surface past the vertical center plane, approximately half of the container diameter is provided as a support length for supporting the container on the secondary support surface 26. Due to the low center of gravity of the partially filled container, the stability of the container even when placed onto the secondary support surface 26 is thus ensured.
Fig. 3 shows that the supporting edge 28 on which the container rests extends substantially annularly at the bottom side of the container.
_g_ Identical reference numerals in the respective figures identify identical parts and thus do not require further explanations.
