Description

DETAILED DESCRIPTION OF THE INVENTION The present invention comprises an ear projecting radially outwardly beyond and connected to the edge of a package container, the ear having a pointed portion on its underside. The present invention relates to a package for foods, etc., which is sealed by a covering foil on the opening side, which forms a punching tool.

Such a package with a so-called opener is known from German Patent No. 1,290,481.

In this case, the piercing tool is formed by a freely cut strip section of the container edge. The free end of this strip portion forms a point in the form of a piercing bar on its underside. This strip section, which extends in a floating manner along the edge of the container, can be lifted and rotated onto the pierceable area of the covering foil for piercing. In this case, if the punching rod deviates from its downward position, the operation becomes difficult.

That is, in that case, great force and speed are required to puncture and perforate. If two holes are to be drilled - in which case it is necessary to further numb the strip part I"]1 - the drilling protrusion is placed in a position at 90° to the practical direction B. Therefore, the strip part In order to guide the corrective action, the operator must hold the package tightly in his hand, during which time overpressure often occurs, so that during the perforation, some of the filling material does not eject. It has to be 2fL.

The object of the present invention is to eliminate the above-mentioned disadvantages and to provide a similar type of piercing tool with a piercing tool, in such a way that the piercing tool can be easily manipulated and can be used as a closure plug. G-) Forming a package.

This object is achieved by the features of patent claim 1.

The claims 2 to 6 are further advantageous embodiments of the subject matter of the invention.

With the above structure, it is possible to obtain a food package that can be easily opened and does not suffer from the above-mentioned drawbacks when opened. The perforator in the covered foil embodiment remains integral with the package until it is used, and can be easily separated from the edge of the container during use. The piercing tool is held at the edge of the container through the break point (planned break point) so as not to be lost.
The user immediately knows that this drilling tool is a means associated with removal of the filling, since the drilling tool has a graspable protrusion formed in the shape of an ear. This is because the break point is in close contact with the covering foil and the piercing tool, so that, in addition to its original function as a piercing tool, it has the additional function of reinforcing the plane of the ear in the area of the break point. Even if the deep-drawn material is very bendable, the entire area on the tearing side has a stable surface and is not easy to bend.Therefore, the ears can be folded accurately.The break point should be the center of the container and the covering foil, and the perforation Advantageously, it lies in a radial line between the centers of the tool.The piercing tool, which has been completely separated from the container, can be used to close the removal hole after removing a portion of the filling. This closure can prevent the filling from drying, condensing or evaporating for a while.Additionally, for example, if the filling is condensed milk,
In this case, the filling material will not harden in the hole and block it. Furthermore, it is advantageous if the covering foil embodiment and the perforator are provided in the flared central part of the ear, the extended end of the ear being connected to the container edge via a second breaking point.

This forms an enlarged handle. This enlarged central part of the ear is the part of the hand that provides opening pressure and allows the thumb to rest easily. Since the enlarged area is larger than the cross-sectional area of the punch, it is advantageous to prevent the filling material from ejecting even if the internal pressure of the container is higher than the normal pressure. As in the case of very small packages that need to be removed,
In the case of relatively small piercing 7 punches which require a large gripping area, it is sufficient for the ears to protrude in a radial line up to the tongue grip of the gripping part. Furthermore, it is preferable that the break point is formed by a notch that cuts out all of the covering foil and part of the protruding container edge. Such a notch, in conjunction with the reinforcement by the punch described above, can be used even if the breaking force exerted on the punch does not act in the desired bending direction.
The advantage is that the punch can be folded neatly.

Since the covering foil is completely cut, the covering foil will never come off by breaking off the punch and removing it.

The container is therefore sealed until the piercing tool is used. Advantageously, the cutout is located approximately tangentially to the circular container edge. Thereby, it can be formed integrally with the container edge. In this case, the area of the ear becomes larger. Furthermore, it is preferred that the foil piercing tool is designed as a hollow conical section opening upwards, which conical section together with the ears is closed or covered by the covering foil.

Further advantages and details of the object of the invention will be explained in more detail below on the basis of two illustrated exemplary embodiments.

The sealable package for food products etc. shown in the figure consists of a cup-shaped container 1 of somewhat conical design.

The wall 2 of this container has an upper, horizontally outwardly directed edge 3
4, the container 1 is formed as a deep-drawn part of plastic material. The edge 3, which itself is not plastically shaped, retains approximately its original thickness.

The container opening is hermetically covered with a covering foil 4. This covering foil is typically aluminum foil. The covering foil is sealed to the rim 3 of the container. The manufacturing of this package involves deep drawing, filling, sealing and stamping steps.

During stamping, the edge of the container 1 takes on its final shape. The container is removed from the waste separation grid. In some cases, edge bridges can be left, so that a group of packages of a large number of containers 1 can be separated and connected.

The package-container rim 3 adjoins a fingertip-sized ear F which projects outwardly at the same level. The thickness of this ear F is the same as the thickness of the edge 3. This ear F is
A coated foil punching tool 6 having a pointed end 5 is formed. This corresponds to the conical part 7 with the σ aperture @rl-. The base or inner conical space 7', which opens above this conical part, is closed by a covering foil 4, and the tip 5id points vertically downwards.

The ear F' is connected to the container rim 3 via the breaking point S6
, this point of rupture S is close to the conical part 7 forming the piercing piercing device and is transverse to the radial line R between the center of the container and the center of the conical part 7. In the first example,
A break point (scheduled break point) S is formed by a cutout 3''. With this cutout, the tightly sealed covering foil is completely separated, and the protruding container edge 3 is Partially cut out 1, this notch 3
'' extends approximately tangentially to the circular container edge 3. Since the outer container edge 3' is circular, the segment-like section of the edge 3 lies in the area of the ear F6, while on the other hand , after folding the ear F, the container 1 is sealed and the notch 3''
In the embodiment shown in FIGS. 1 to 3, the ears 1i' are enlarged (-/) and protrude beyond the central part with a tongue-shaped gripping part 10. The outer edge is convexly rounded 7: rounded, and the throat 8,9
through which it transitions continuously to the circular outer edge 5' of the container.

Doo I'6, which is equipped with a punching tool 6 for punching the covered foil, when grasping the gripping part 10 of the ear and pushing it in the direction F, it is easily broken from the region of the notch 3' at the breaking point S. .

A piercing tool 6 is placed on any point of the covering foil 4, in particular near the inner edge, and a hole is made 5, through which the filling can be removed 3. If necessary, diametrically Two holes can be drilled on opposite edge numbers. If there is only one hole, the filling can be pushed out by means of a cover foil 4 that can be manipulated in the form of a diaphragm, and the plug can be plugged using a piercing tool 6 (resealing the package from L). be able to.

, the conical part 7 reinforces the area T:″V- in the vicinity of the break point. This has an advantageous effect on the separation of the ear F.
Therefore, the ear can be detached by simply tilting the ear slightly downward. This separation is completed before the tip 5 of the conical part 7 comes close to touching the wall 2. Furthermore, the complete covering of the ears by the covering foil 4 leads to reinforcement of the plane. By sealing the covering foil 4, the plane is greatly reinforced, even if the covering foil is a very pliable material.

In the embodiment of FIGS. 1-3, the notch extending perpendicularly to the radial line R is indicated by the line L--L. Thus, while the break line in the embodiments of Figures 1 to 3 extends along the line L-L, in the embodiment of Figure 4.5, the break line extends along the outer edge 3' of the circular container. It extends. By forming the break line over a portion of the outer periphery of the container, the overall length of the coated foil piercing tool 6 is increased. However, in this case, it is not necessary to make the piercing tool 6 protrude greatly in the radial direction. In this case too, the conical part 7 is located in the planar enlarged central part of the ear F. The part which widens to the size of the fingertip extends in its outer region parallel to the circle at the base of the conical part and then into the throat part 8.
9, on the one hand, a gripping part 10 which follows the tapered ear end part 11 and, on the other hand, is oriented in the circumferential direction of the container 1.
is formed. This grip protrudes like a tongue that can be easily grasped.

In this embodiment, the break point Si, S2 is formed in the form of a small bridge3, the break point S1 intersecting the radial line R between the center of the container and the center of the cone. The second break point S2 is formed by a bridge provided at the end of the end portion 11 of the ear. In this case, the end part 11 is fixed to the edge 3.

By moving the covered foil punching tool 6 in a folding manner,
This piercing tool can be easily removed from the edge 3 of the container 1. In this case too, the planar reinforcing effect of the conical section 7 facilitates rupture. After cutting off the break point S1, the bridge at the break point S2 can be easily separated by bending the ears F downward. This breaking point S2 is the end portion 1 of the ear.
A long operating handle in the shape of 1 is connected to the container. The end section 11 tapers continuously up to the cross section forming the break point. The coated foil punching tool 6 is inserted into the container edge 3 about 4 times.
It extends for 1/2.

All features of novelty described above and illustrated are essential to the invention, even if these features are not recited in the claims.
