DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food container with an inner lid used for storing various foods such as fermented milk such as yogurt and jam, and more particularly, to a bottomed cylindrical container having a ring around its opening. A container body having an overhang, an inner lid releasably polymerized and bonded to an annular overhang of the container so as to seal the opening of the container body, and a container body from the outside of the inner lid. The present invention relates to a food container with an inner lid comprising an outer lid formed so as to be elastically fitted to and removed from a container body so as to close an opening.

[0002]

2. Description of the Related Art In this kind of food container with a middle lid,
From the time of transportation until the sale at stores, etc. is completed, in order to maintain the quality of the stored food for a long period of time and to maintain sanitary control, the opening of the container body is closed. Double-closed state with the inner lid and the outer lid such that the outer lid is elastically fitted to the container body to close the opening of the container body from the outside of the inner lid after polymerizing and bonding the parts On the other hand, on the consumer side, after removing the inner lid, taking out the food and serving it for consumption, only the outer lid is required to close the opening of the container body to store the remaining food in a refrigerator etc. Is generally handled in a single closed state by the outer lid alone, such as by elastically fitting the outer lid to the container body.

As described above, in a food container with an inner lid which is handled in a double or single closed state, the following configuration has been conventionally employed as an elastic fitting structure of the outer lid to the container body. That is, as shown in FIGS. 7 and 8, an annular overhang 23 formed around the opening 22 a of the container body 22 on the peripheral wall 21 a of the outer lid 21 and a surface of the annular overhang 23 are overlapped. An annular fitting / removing portion 2 elastically fitted / removable with respect to the peripheral portion 24a of the bonded inner lid 24
5 is formed in only one step, and the annular fitting portion 25 is provided with the annular projecting portion 23 of the container body 22 in either the double closed state shown in FIG. 7 or the single closed state shown in FIG. A configuration has been adopted in which the elastic member is elastically fitted to the substrate.

[0004]

However, in a conventional food container with a middle lid employing the above-described elastic fitting structure with the one-stage annular fitting / unlocking portion 25, the middle lid 24 is left in a state of being polymerized and adhered. The outer lid 21 is attached to the annular projecting portion 2 of the container body 22.
3, the inner lid 24 is peeled off and the outer lid 21 is attached to the annular projecting portion 23 of the container body 22 against the holding force in a double closed state (FIG. 7) elastically fitted to the outer lid 21. The holding force in a single closed state (FIG. 8) elastically fitted to the inner cover 24 is reduced by an amount equivalent to the thickness of the inner lid 24, and the difference in the holding force causes two in the single closed state. Not only is the sealing performance extremely reduced compared to when the lid is heavy, the preservability of the food tends to deteriorate,
For example, there has been a problem that it is difficult to handle the container in a normally closed state because the outer cover is accidentally detached or inclined obliquely when the container is put in or taken out of the refrigerator.

It is also conceivable to solve the above-mentioned problem by increasing the holding force in a single closed state (FIG. 8). When detaching the outer lid from the double closed state in order to further increase the fitting holding force, a very large force is required for the detachment, and the outer lid 21 is forcibly detached by applying a large force. As a result, the annular fitting portion 25 of the outer lid 21 and the peripheral wall portion 21a forming the outer lid portion 21 or the annular projecting portion 23 on the container body 22 side are easily damaged, and as a result, after the inner lid 24 is peeled off. It is unavoidable that the fitting and holding force in the single closed state is extremely reduced to cause the same problem as described above.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and provides a large fitting and holding force for the outer lid in the double closed state and also in the single closed state after the inner lid is peeled off. It is an object of the present invention to provide a food container with an inner lid that can achieve a food preserving effect with excellent sealing properties.

In a food container with an inner lid comprising an outer lid formed so as to be resiliently fitted to and releasable from the container body so as to close the opening, an annular tension of the container body is provided on the peripheral wall of the outer lid. A first annular portion having a vertical width corresponding to the total thickness of the projecting portion and the peripheral portion of the inner lid which is superimposed and bonded to the surface thereof, and which can be elastically fitted to and removed from the annular projecting portion and the peripheral portion of the inner lid. A fitting part,
A second annular fitting / removing portion having an upper / lower width corresponding to the thickness of the annular extending portion of the container body in a state where the inner lid is peeled, and capable of elastically fitting / removing with respect to the annular extending portion; Are formed in two steps with the second annular fitting / disengaging portion side positioned close to the front wall surface of the outer lid, and the outer lid is elastically attached to the container body on the front wall surface of the outer lid. When fitting is performed, the fitting restricting protrusion that abuts on the surface of the inner lid and allows elastic fitting of only the first annular fitting / removing portion to the annular projecting portion of the container body and the peripheral portion of the inner lid is provided. It is characterized by being formed.

A food container with an inner lid according to a second aspect of the present invention comprises a container body having a bottomed cylindrical shape having an annular projection formed around an opening thereof, and an opening of the container body. An inner lid whose peripheral portion is polymerized and bonded so that it can be peeled off in a folded manner from the surface of the annular projecting portion of the container main body to the following outer peripheral surface so as to be hermetically sealed, and the opening of the container main body is closed from the outside of the inner lid. And an outer lid formed so as to be resiliently fitted and disengaged from the container body so that the outer wall of the outer cover has an annular projection of the container body and a surface thereof. They have upper and lower widths corresponding to the total thickness of the peripheral portion of the inner lid that is superimposed and bonded, and protrude outward by the thickness of the folded peripheral portion of the inner lid that is superposed and bonded to the outer peripheral surface of the annular overhang. It can be elastically fitted to and removed from the annular overhang and the periphery of the inner lid 1 has an upper and lower width corresponding to the thickness of the annular projecting portion of the container main body in a state where the inner lid is peeled off, and is inward by the thickness of the folded peripheral portion of the inner lid. A second annular fitting / removing portion which can be elastically fitted / removed with respect to the annular projecting portion of the container main body when the second annular fitting / removing portion is positioned closer to the front wall surface of the outer lid; When the outer lid is elastically fitted to the container main body, the outer lid comes into contact with the surface of the inner lid and the annular projecting portion and It is characterized in that a fitting restricting protruding portion that allows elastic fitting of only the first annular fitting / removing portion to the peripheral portion of the lid is formed.

According to the food container of the present invention having the above-described structure, the periphery of the inner lid is formed from the surface of the annular projecting portion of the container body to the outer peripheral surface following the surface so as to seal the opening of the container body. When the outer lid is elastically fitted so as to close the opening of the container body from the outside of the inner lid at the stage where the parts are polymerized and adhered, and the double lid is closed, the outer lid surface is The fitting restricting protrusion formed on the outer lid abuts on the surface of the inner lid, whereby further pushing movement of the outer lid is restricted, and the annular fitting formed in two steps on the outer lid peripheral wall portion Only the first annular fitting / removing portion of the removing portion located far from the front wall surface of the outer lid is elastically fitted to the annular projecting portion of the container body and the peripheral portion of the inner lid. The first annular fitting portion has a vertical width corresponding to the total thickness of the annular projecting portion of the container body and the peripheral portion of the inner lid, and the peripheral portion of the inner lid is formed of the annular projecting portion of the container main body. In the case of a form in which the outer lid is polymerized and adhered in a folded shape from the surface to the subsequent outer peripheral surface, the outer lid protrudes outward by the thickness of the folded peripheral portion of the inner lid, so that the outer lid can be applied without applying excessive force to the outer lid. Can be easily and firmly fitted and held in the container body. Further, since the fitting restricting projection is in contact with the inner lid surface, the outer lid is not fitted diagonally, and the entire circumference of the first annular fitting / unlocking portion is formed by the annular projection of the container body. A normal closed posture elastically fitted over the entire periphery of the portion and the peripheral portion of the inner lid can be obtained.

On the other hand, on the consumer side of the stored food, after the inner lid is peeled off, only the outer lid is elastically fitted to the container main body so as to close the opening of the container body again, and the outer lid alone is in a single closed state. In this case, since there is no inner lid, the restriction of the pushing movement by the contact of the fitting restriction projecting part is released, and the annular fitting part is formed in two steps on the outer lid peripheral wall. The second annular fitting / disengaging portion located near the front wall portion of the outer lid is elastically fitted to the annular projecting portion of the container body. This second
Has an up-down width corresponding to the thickness of the annular overhang of the container body, and has a folded shape in which the peripheral portion of the inner lid extends from the surface of the annular overhang of the container body to the outer peripheral surface following it. In the case of the type that is polymerized and adhered to the inner lid, the inner lid has been retracted inward by the thickness of the folded part, so the outer lid can be firmly fitted and held in the container body without loosening. In spite of the single lid, it is possible to enhance the preservability of the food without lowering the sealing performance inside the container body and to prevent the occurrence of the inconvenience that the outer lid is unexpectedly detached during handling.

[0011] In the food container with a middle lid according to the first or second aspect, as described in the third aspect, the fitting regulating protrusion formed on the front wall surface of the outer lid may include a middle lid. By forming the contact portion with the surface flat and annular, it is possible to increase the shape-retaining strength of the outer lid, which is generally formed of a thin resin, and to attach the outer lid from the outside of the inner lid to the container body. When the cover is pushed into the double-closed state as described above, the pushing force applied to the outer cover can be dispersed over a wide range of the inner cover, so that the fitting restricting protruding portion is applied locally to the inner cover. The outer lid can be fitted so as to be in a normal double-closed posture without tilting the outer lid without damaging or depressing the portion at the contact.
