Description

[Detailed Description of the Invention] The present invention relates to a container equipped with a hot water outlet for instant noodles, specifically instant fried noodles.

As is well known, for instant yakisoba, boiling water is poured into a container, the lid is closed, and the container is left for several minutes.Then, the container is tilted with the lid closed to release the hot water inside.

Therefore, in this type of container, it is necessary to provide the container or the lid with a hot water outlet through which the hot water inside can be discharged while the lid is closed.

Conventionally, as a container equipped with such a hot water outlet, the first
As shown in the figure, it is widely known that a notch-shaped hot water outlet 31 is provided on the periphery 2 of the container 1 (Utility Model Application No. 51-25006).
.

Another option is to provide a bulge 6 larger than the surface of the lid container 5 on a part of the periphery 5 of the lid 4 which is fitted onto the periphery 2 of the container 1, as shown in FIG. As a result, the hot water outlet 32 is in a state where the back side of the bulging portion 6 does not come into contact with the container periphery 2.
Tomo is known (Utility Model Publication No. 51-25004)
.

However, the provision of a notched hot water outlet 31 on the periphery 2 of the container 1 as shown in FIG. 1 has a major drawback in that the strength of the container itself is weakened by cutting out a part of the periphery of the container.

That is, this type of container is made of thin styrene resin because it is disposable, and therefore the periphery 2 of the container 1 is required to be folded to provide strength to the container itself.

By the way, providing the hot water outlet 31 by cutting out a part of the periphery 2, which maintains the strength of the container itself by providing folds as described above, will significantly reduce the strength of the container itself. It cannot be said that the shape of this is preferable.

In particular, when this hot water outlet 31 is provided, it is necessary to provide an air inlet of a similar shape on the symmetrical side of the hot water outlet 31, which further reduces the strength of the container itself.

In addition, providing such a notch means that even if the cut surface is beautifully finished, if the container is subjected to impact during transportation or handling at a noodle factory, cracks may occur in the container itself from the notch hot water outlet. There is a large possibility that this will occur, and from this point of view, it is undesirable to provide a hot water outlet in the form of a notch on the periphery of the container.

On the other hand, when a hot water outlet 31 is provided by processing the peripheral edge 5 of the lid 4 as shown in FIG. In order to form the lid 4, the surface and outer circumferential surface of the lid 4 naturally protrude excessively, and when closing a container at a noodle factory, one lid is removed from a large number of lids and moved. There is a problem that it is difficult to carry out the work for preparing the product, and that these bulges 6 get in the way of each other when packaging the product in a box.

The biggest problem with providing such a bulge 6 is that a step is formed at the boundary between the bulge 6 and the landing edge 5, and the lid 4
Since it is made of an extremely thin resin plate, the stepped portions at these boundaries are even thinner and are extremely susceptible to damage due to impact.

This proposal is based on the above-mentioned problems with conventional containers of this type.
A new product that can provide a hot water outlet that can reliably release hot water without having to provide a hot water outlet with a notch in the container itself, and without providing a bulge on the lid that protrudes from the top surface or outer circumference. The purpose of this invention is to provide an instant noodle container for hot water brewing.

Next, the present invention will be described in detail with reference to the illustrated embodiment. FIG. 3 is a perspective view of the container 11 made of thermoplastic resin, and FIG. 4 is a perspective view of the back side of the lid 15.

The container 11 is a rectangular container, and circular arcs 13 of the same shape are formed at each of the four corners of the peripheral edge 12, and the peripheral edge 12 is formed on the same level surface without any notches or unevenness, A locking step 14 is provided around the inner side of the peripheral edge 2.

On the other hand, the lid 15 has a container periphery in which one corner 16 forms a small circular arc that is closer to an angular shape than each arc 13 of the container periphery 12, and the other corners have approximately the same shape as the circular arcs 13 of the container periphery 12. It has a fitting groove 17 for 12.

The fitting groove 17 is connected to the center of the lid 15 via a groove 18 provided along the inner periphery of the fitting groove 17 .

Therefore, as shown in FIG.
9 is locked on the locking stage 14 of the container 11, so that the lid can be stably placed on the container 11.

Further, the height H of the fitting groove 17 is larger than the height h between the container peripheral edge 12 and the container locking step 14, and as described above, the inner end 19 of the inter-lid groove 18 is above the container locking step 14. When the fitting groove 17 is fitted to the container periphery 12 in a locked state, a gap 21 is formed between the inner top surface 20 of the fitting groove and the container periphery 12. .

Further, on the outer peripheral surface of the fitting groove 17, there is provided a lower outer peripheral edge 12 of the container peripheral edge 2.
' is provided with a recess 22 which engages with the lid 1.
5 is secured to the container 11 as described above, the inner end 19 of the recessed groove is secured on the container locking step 14 and the recessed portion 22 is engaged with the lower edge 12' of the outer periphery of the container. Obtain a closed state.

Furthermore, the inner surface 23 of the fitting groove 17 and the inner surface 2 of the container periphery 12
4 has a tapered cross section so that they come into close contact with each other, and the container 1
1 is tilted, hot water is blocked by the contact surface between the fitting groove inner surface 23 and the container peripheral inner surface 24.

On the other hand, at the inner corner of the fitting groove 17 in the rectangular corner 16 of the lid 15, there is an inclined surface 25 extending from the inner end 19 of the groove 18 to the inner top surface 20 of the fitting groove 17, as shown in FIGS. 4 and 6. Therefore, when the lid 15 is placed on the container 11, the square corner 16 is provided with a gap 21 above the container periphery 12 from the inner surface of the inclined surface 25. A leaching channel 26 is formed that reaches the inner surface.

In the above embodiment, the groove 18 is provided inside the fitting groove 17 in the lid 15.
8 is not necessary, and the main part of the lid 15, the main part of the fitting groove 15, and the fitting groove 17 may be continuous.

Of course, even in this case, it is necessary that a part of the lid 15 is locked onto the container locking stage 14, and therefore, in this case, the inner end 19 of the groove 18 is used as the inner end 19 of the fitting groove 17. shown.

As described above, in the instant noodle container according to the present invention, the height H of the outer periphery fitting groove 17 of the lid 15 fitted to the container periphery 12 is
2 and the locking step 14 on the inner side thereof, the fitting groove 17 can be attached to the container periphery 12 with the inner end 19 of the fitting groove 17 locked to the locking step 14. In the fitted state, a gap 21 is formed on the container periphery 12), and the fitting groove 1 of the square corner 16 in the lid 14 is formed.
7 an inclined surface 25 facing the inner top surface 20 of the fitting groove 17 on the inner side;
, it is possible to provide a leaching channel 26 extending from the inner surface of the inclined surface 25 through the gap 21 to the square corner 16 of the lid 14.

Therefore, with this container, there is no need to provide a notch at the periphery of the container unlike in conventional containers, unlike the provision of a hot water outlet, so there is no risk of damaging the strength of the container. It is possible to reliably eliminate the possibility that the container itself will crack when subjected to impact.

Regarding the lid 15, the flow path 26 as a hot water outlet can utilize the gap 21 between the container peripheral edge 12 and the fitting groove 17. It can be formed by simply providing the inclined surface 25 over the top surface 20.

Therefore, there is no need to provide a bulge on the outer periphery of the lid unlike when a conventional lid is provided with a hot water outlet, so there is no need to create a bulge on the outer periphery of the lid, and there is no need to create an unnecessary protrusion. This has the practical benefit of eliminating the loss of material and the loss of strength of the lid itself, and providing a rational container.
