Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a container with a lid for accommodating objects such as instant foods such as snack noodles.

[0002]

2. Description of the Related Art Conventionally, containers of this kind with a lid include:
2. Description of the Related Art There is known a device provided with a bottomed cylindrical plastic container main body that opens upward and a lid made of a sheet material that closes an opening of the container main body. Then, for example, a snack noodle is stored in the container body, and the lid is adhered to the upper surface of the flange portion provided around the upper end of the container body by heat sealing so as to be peelable.

When eating stored snack noodles,
The lid is swelled outward from the flange, and the lid is peeled off to approximately half while being pulled up and partially opened, and hot water is poured from the substantially half-opened opening.

As described above, in this type of container, it is necessary to pour hot water while maintaining the state in which the tab side of the lid is rolled up. Therefore, it is configured such that a necessary shape-retaining property is secured by using a sheet material on which an aluminum foil is laminated for the lid, and the partially opened state can be maintained by the rigidity of the lid itself.

[0005]

However, due to recent environmental problems, the need for aluminum-less is demanded. Besides,
If the aluminum foil is contained in the lid of the container, the metal detector cannot be used in the production process, and there is also a problem that it is not easy to find foreign matter.

Therefore, it is conceivable to use a sheet material having no aluminum foil for the lid. However, since the sheet material is inferior in shape retention, even if the lid is turned up when pouring hot water, a hand is required from the knob. When it is released, it returns to its original flat state so as to close the opening by its elastic restoring force, which is inconvenient.

On the other hand, Japanese Patent Laid-Open No. 2000-26437
No. 9 discloses a locking portion which can be locked to each other at two positions, that is, a knob portion of a lid and a position facing the knob portion. When pouring hot water, the locking portion of the knob portion is connected to the other engaging portion. There has been proposed a configuration in which an unsealed state is to be maintained by engaging a stop portion.

However, since the locking portion of the knob portion is locked to the lid itself having poor rigidity, there is a problem that it is unstable and it is difficult to reliably maintain the partially opened state.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a container with a lid that can reliably and easily maintain a partially opened state of the lid with a simple configuration. I do.

[0010]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a container with a lid according to the present invention has a bottomed cylindrical container body which opens upward, and a container body. A lid that closes the opening of the container body, a flange portion protruding outward is formed at the upper end of the container body over the entire circumference, and the lid is made of a flexible sheet material. In the case of a container with a lid that is provided with a knob for opening and that is peelably adhered to the upper surface of the flange portion, when the knob portion side of the lid is partially opened, A hook is formed on the knob so that the lid can be kept partially opened by hooking the knob on the flange.

It is preferable that the hooking portion is a tongue that is convex inside the lid. Further, it is preferable that the tongue portion is formed by forming a cut in the knob portion.
Further, it is preferable that the front end of the flange portion faces downward.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a container with a lid according to the present invention will be described with reference to the drawings. A container with a lid provided with the lid 2 will be described.

The container body 1 is formed by injection molding of a synthetic resin or the like. For example, polypropylene, polyethylene, polystyrene and their foamed resins are used. At the upper end of the container body 1, a flange portion 3 protruding outward is formed over the entire circumference.

As shown in FIG. 3, the flange portion 3 is generally formed into a substantially U-shape in cross section, and its tip 3a faces downward. More specifically, in this embodiment,
The flange portion 3 is protruded substantially horizontally from the body portion 4 of the container body 1 so as to form a flat, fixed width bonding surface for bonding the lid 2 to the upper end portion of the container body 1. Tip 3a
It has a shape that is bent at a substantially right angle downward in the middle so that the portion faces downward.

The lid 2 is adhered to the upper surface of the flange 3 as such an adhesive surface. The lid 2 is formed of a sheet material made of a synthetic resin having a thickness of about 25 to 50 μm, such as a flexible biaxially stretched polyester. In the present embodiment, the lid 2 is detachable from the flange portion 3 by heat sealing. Glued. Therefore, the lid 2 is composed of a multilayer sheet material having, for example, a polypropylene-based easy peel sealant layer (a sealant layer that can be peeled or broken after heat sealing) as the lowermost layer.

The lid 2 is formed in a circular shape as a whole corresponding to the opening of the container body 1, and has a knob 5 for opening which is bulged outward in a part thereof. are doing. Therefore, when the container body 1 is closed, the knob 5 protrudes outward from the flange 3, and the lid 2 can be easily opened by grasping the knob 5. On the other hand,
Since the lid 2 is made of a sheet material having no metal foil such as an aluminum foil, a hook portion is formed on the knob 5 in order to maintain the partially opened state. As shown in FIGS. 2 and 3, the hook portion is configured to be hooked on the flange portion 3 at a position facing the knob portion 5, and the lid 2 attempts to return to its original state by its elastic restoring force. To block.

More specifically, a tongue 6 protruding inward from the lid 2 is formed at a substantially central portion of the knob 5 as a hook. The tongue portion 6 is formed by forming a substantially U-shaped notch outside the knob 5 (in the direction in which the knob 5 bulges) so that the opening of the U faces. In the present embodiment, a total of three tongue parts 6 are continuously arranged in the horizontal direction.

When maintaining the partially opened state,
As shown in FIG. 3, the tongue 6 is hooked below the tip 3a of the flange 3 facing downward. In the hooked state, the tongue portion 6 is in a state in which its base end is on the outside and its tip end is facing the center of the container body 1. in this way,
Since the tongue portion 6 is formed in the knob portion 5, the tongue portion 6 can be easily hooked to the flange portion 3 with one operation in a flow operation while holding the knob portion 5 at the time of opening.

When the outwardly projecting tongue portion 6 is used, it is necessary to bend the tongue portion 6 at its base end and hook it on the flange portion 3, and to stabilize the bent state. Also lacks. On the other hand, by making the tongue portion 6 convex inward as in the present embodiment, not only the advantage of the work surface that bending work is not required, but also the tongue portion 6 is formed by the elastic restoring force of the sheet material. In order to automatically return to the original closed state from the open state as shown in FIG. 3, there is an advantage that the hooked state can be reliably maintained despite the simple configuration.

Further, since the lid 2 is hooked on the flange 3 of the container body 1 having a greater rigidity than the lid 2, the partially opened state can be reliably and stably maintained as compared with the conventional configuration in which the lids 2 are hooked together. . In particular, since the tip 3a is configured to be hooked on the flange portion 3 facing downward, the tip 3a
Can be more reliably maintained in the hooked state as compared with the configuration in which the hook is hooked on the substantially horizontal flange portion 3.

In the present embodiment, the plurality of tongues 6 are provided intensively at one location substantially at the center of the knob 5.
As shown in FIG. 4, a plurality of tongue parts 6 may be provided separately at several places. In the case of such a distributed arrangement, since the hook can be hooked at intervals at several places in the circumferential direction of the flange portion 3, the certainty of the hooked state is higher than in the case of the centralized arrangement. The work of hooking work increases relatively. On the other hand, in the case of the centralized arrangement, there is an advantage that the operation from the opening operation to the operation of hooking on the flange portion 3 can be easily performed by a series of operations as described above. In the case of dispersive arrangement as shown in FIG. 5, it is preferable that the tongue portion 6 be convex toward the center of the container. In other words, the projection of the tongue portion 6 is directed in the normal direction to the flange portion 3.

In addition to forming the tongue 6 by forming a predetermined cut in the knob 5, the tongue 6 is formed in the knob 5 by forming the knob 5 itself into a predetermined shape. You can also. For example, as shown in FIG.
By forming a predetermined notch in the edge of the knob 5,
It is also possible to form the knob 5 itself in a substantially T-shape as a whole and to provide the tongues 6 at both ends. Of course, the tongue part 6 may be one place. In any case, by forming the convex tongue portion 6 inside the lid 2, the hook can be securely and easily hooked with a simple configuration.

The shape of the tongue portion 6 is not limited to a substantially U-shape, and can be appropriately changed in design such as a substantially V-shape or a substantially U-shape. Of course, it is also possible to use a hook portion other than such a tongue portion 6.

In the above embodiment, the entire lid 2 including the knob 5 is made uniform in thickness. However, the thickness of the knob 5 alone may be increased to reinforce it. That is, a separate label is attached only to the knob 5, or the thickness of the sheet material itself is partially changed. As other reinforcements,
For example, it is possible to emboss only the knob 5.

On the other hand, the distal end 3a of the flange portion 3 is particularly preferably vertically downward as in the above-described embodiment. However, the distal end 3a is bent at 90 degrees or more toward the body portion 4 side of the container body 1, or conversely. The shape may be such that the angle is shallow and the tip 3a faces obliquely downward and outward. In any case, it is preferable to point the tip 3a downward because the partially opened state can be maintained more reliably. However, flange 3
Can be made substantially horizontal.

In the present embodiment, the flange 3 with the tip 3a facing downward is formed over the entire circumference, but the tip 3a of the flange 3 at a position facing the knob 5 is formed.
Only one may face downward.

In any case, since the hook formed on the knob 5 of the lid 2 is hooked on the flange 3 having a greater rigidity than the lid 2, the partially opened state can be reliably maintained.

In addition, the shape of the container body 1 is not limited to a cylindrical shape, but may be a rectangular tube shape.

[0029]

As described above, the hook portion of the knob portion is hooked on the flange portion of the container body having a greater rigidity than the lid, so that the lid has a simple structure and is surely and easily. The partially opened state can be maintained.
