[0001]

The present invention relates to a top member, a bottom member,
A cup-shaped member including a side wall member and at least one breaking tear tab, the cup roof portion forming a cup rim portion and the top member, and a cup side wall portion extending from the cup roof portion to the cup rim portion; A sealed container for food products having a substantially flat container sealing lid member for engaging a cup-shaped member.

[0002]

2. Description of the Related Art Generally, a container having a cup-shaped member containing a solid food or a food such as a confectionery is well known.

[0003]

In order to make use of the food product inside, and to invert this container so that it can be placed in a dish in a shaped form, such as in the case of mousse-shaped confectionery or jellies. You have to drop it.

However, it has been found that even if the consumer falls over the cup-shaped member, the percentage of the contents of the container that can be taken out is very small. The main reason for this is that the contents themselves rarely separate correctly or completely from the cup-shaped member, and many steps have to be taken to serve the contents on the table.

[0005]

SUMMARY OF THE INVENTION Accordingly, the present invention is directed to at least one break opening tab and the breaking of the container by pulling up the break tab generally from the cup rim portion of the cup-shaped member to its cup sidewall portion. A sealed container for food having a breaking path guiding means configured to occur in a direction toward a roof portion.

In the present invention, the sealing lid member forms the bottom member of the container, and the opening tab is arranged on the cup rim portion, and this tab and / or the rim portion guides the path of breaking of the container by pulling up the tab. Means for opening the jacket portion defined between the break lines of the side wall portions when the container is opened by the tab, and the path of the break of the side wall portions set by the break lines is from the cup rim portion to the cup side wall portion. The structure is arranged as if going through the proof part.

[0007]

In the sealed container for food of the present invention, the breakage of the side wall portion of the cup-shaped member is along the path substantially coincident with the steepest slope line or generatrix thereof, and the contents of the cup-shaped member itself from the cup side wall portion. The contents themselves are already in the proper position after the opening of the peelable container, and the lid member functions as a dish for receiving it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The figures show an embodiment of a container in a ready-to-use state before opening, i.e. on a shelf in a food store.

The container is typically a couple roof portion 2.
And a cup-shaped member having a cup side wall portion 3 up to the cup rim portion 1 (FIGS. 3 and 6) and a dish-shaped sealing lid member 14 forming the bottom of the container.

Ring-shaped or annular thread bottom or protrusion 16
Is formed on the bottom 15 of the dish-shaped sealing lid member 14. This thread bottom 16 is placed directly against the support when the containers are placed on a support such as a shelf, or when the containers are stacked one on top of the cup roof portion of the lower container. . An annular sealing rib 5 projects upwards from the bottom 15 and a bead 17 is formed on the side wall of this rib 5. The dish-shaped rim portion 8 extends along the periphery of the lid member of the container 14.

As shown in FIG. 6, an inner peripheral bead in the form of a seal projection 6 is formed inward at the boundary between the cup side wall portion 3 and the cup rim portion 1. The seal protrusion 6 contacts the seal rib 5 at a position below the bead 17. Thus, the upper cup-shaped member of the container snaps into engagement with the dish-shaped lid member 14 to seal the inner space of the container against the surroundings.

A peripheral rim portion 9 is further formed around the cup rib portion 1. The peripheral rim portion 9 overlaps the dish-shaped rim portion 8 of the lid member and protects the portion 8 from dust and the like.

A break open tab 4 is provided on the peripheral rim portion 9. This tab 4 aligns with but does not overlap with the dish-shaped rim portion 8. Peripheral rim part 9 for easy finger grip
This tab 4 having a portion projecting radially outward from
The area of is limited to the peripheral rim portion 9 between the substantially Z-shaped breaking guide lines 19, 20. These breaking guide lines 19, 2
0 communicates with slots 10 and 11 extending from the cup rim portion 1 to the cup side wall portion 3, respectively. Therefore, the opening tab 4 is basically connected only to the cup side wall portion 3. Two webs 12, 13 are formed on the tab 4, which webs are parallel to one another and extend to the cup rim 1 and are integrally connected thereto. That is, these webs completely fill the annular groove 18 created by the U-section of the cup rim 1. The webs 12, 13 are further side walls 3
It extends to and is connected integrally there.

The slots 10, 11 and the webs 12, 13 and the breaking guide lines 19, 20 together form means for guiding the breaking of the cup side wall part 3 when breaking and opening the cup side wall part 3. Therefore the webs 12, 13 are in the slots 10,
It is located inside 11, ie in the region between them.

Slot 10, web 12, break guide line 1
9 is the first guide part of the means, slot 11, web 1
3 and the breaking guide wire 20 form a second guide portion.

[0016] Generally, two breaks formed when a wall such as a lid, cover or top of a plastic or metal (eg aluminum foil) container is broken at two places and it is not done correctly. The lines are not parallel to each other, but occur inwardly toward each other and tend to extend in the form of two sides of an acute isosceles triangle. The apex of this triangle is thus in front of the edge of the wall or top cover, leaving part of the cover, for example of an aluminum foil, only a small triangular opening. This problem is generally due to improper tab pulling or defective containers, an example of which is found in known coffee cream containers.

In the container of the present invention, two guides, each consisting of a slot, a web and a breaking guide line, are arranged at a distance from each other in the peripheral part of the container. This spacing is such that when a break is made in the cup side wall 3, two lines of break as shown at 21 and 22 in FIG. 4 maintain a distance from each other at or near the roof 2 of the cup-shaped member of the container. It is properly selected depending on the material, thickness and height of the cup side wall portion 3 so as to extend.

FIG. 6 is a partial cross-sectional view showing the breaking tear tab 4 and the web 12 projecting therefrom. The tear tab 4 has a groove 23 on its surface and a bead 24 on its lower peripheral surface. This minimizes finger slip when attempting to raise tab 4 in the direction of arrow A to cause a break. Further, a portion 25 between the web 12 and the cup side wall portion 3 has an acute angle.

To open the container, the following operation is performed.

The container is placed on a support, eg a table, in the form shown. It is practically impossible to operate the opening tab 4 when the container sealing lid member 14 supports the container on the table in such a manner that it faces the consumer.

When the opening tab 4 is raised in the direction of arrow A in FIG. 6, the breaking guide lines 19 and 20 are sheared. The center or fulcrum of this raising action is approximately in the region of the groove 18, and the sharp edge 25 of the webs 12, 13 pierces the cup side wall 3 and ruptures it there, the planned break line 21, 22 occurring in that region. The distance is given as above.
Since the tab 4 is separated from the cup rim portion 1 from the slots 10 and 11, the force applied by the tab 4 is transmitted to the side wall portion 3 after breaking the guide wires 19 and 20. Furthermore, this opening force is transmitted by the webs 12, 13 to the side wall 3 and in the region of the cup rim 1 between the slots 10, 11.

Accordingly, the force applied by the tab 4 starts the breaking of the side wall 3 at the cup rim portion 1 toward the cup roof portion, where the breaking opening of the side wall 3 advances in the direction of the generatrix of the side wall 3.

The cup-shaped member is attached to the lid member 14 by the seal-type snap engagement, and when the container is closed, the elastic deformation due to the snap engagement causes stress on the cup rim portion and the side wall portion 3. When the portion 3 is broken and opened, this stress disappears and the cup-shaped member can be easily lifted from the lid member 14.

Since the side wall portion 3 is broken, air can enter between the inner surface of the side wall portion 3 and the contents of the container, separate the contents from the inner surface, and adhere only to the lid member 14. To do. The lid member 14 is dish-shaped so that the contents of the container can be served on the table without the use of a separate dish. Thus, the lid member 14 can also be used as a dish for contents.

FIG. 4 shows another embodiment, which can be used especially for tart confectionery, for example mousse confectionery. In this embodiment, the cup sidewall portion 3 has a molded shape. Further, the opening tab 4 and the break lines 21 and 22 are described in the explanation of the embodiment of FIG. Further, the peripheral rim portion 9 overlying the dish-shaped rim portion 8 of the lid member 14 is shaped in this embodiment not visible from the side shown.

That is, also in this example, the peripheral rim portion 9 overlaps with the dish-shaped rim portion 8 to provide protection against adhesion of dust or the like.

FIG. 5 is a cross section of the container of FIG. 4 applied to a jelly, for example, which is suitable for pouring a fluid thing on the jelly after opening the container. A thin-walled ring 25 is formed on the inner surface of the cup roof part 2. This ring 25, together with the area 26 of the cup roof part 2 which it surrounds, forms a recess which opens towards the inside of the container. When filling the contents of the container, the cup-shaped member is turned upside down, the liquid 27 is placed in the depression defined by the ring 25 and the region 26, and then the jelly 28 is placed in the remaining space of the cup. When the container is opened, the jelly 21 remains in the dish on which the fluid 27 is poured from the depressions 25, 26.

[0028]

EFFECTS OF THE INVENTION By operating the opening tab, the contents of the container are separated from the side wall of the container, and in that state, the contents are placed on the lid member as a plate. Therefore, the table is immediately removed by only removing the cup-shaped member. Can be used for Further, since the periphery of the cup-shaped member is always overlapped with the lid member, it is possible to prevent dust and the like from adhering to the plate.
