Japanese Utility Model Publication No. 02-99749 JP-A-8-244812

  As described above, a container having a box-shaped lid that is conventionally used as a container for butter or margarine is provided with a knife opening for passing a knife, spoon, or the like. And this knife mouth forms the opening tab divided by weak parts, such as a cut perforation line and a thin line, in a part of side of a lid, and when a consumer uses, the opening tab is cut off And a knife mouth for inserting a knife, a spoon or the like is formed.

  And about this opening tab, although it describes that it cuts out in the said patent document 1, since the opened opening tab is small and is not conspicuous, when this mixes in a container, it will take out this. Have difficulty. At present, it is used in a state where it can be folded back into a flap shape in order to solve the problem of processing the cut opening tab. In addition, by making the opening tab swingable like a flap in this way, the knife mouth can be covered when a knife, a spoon, or the like is not inserted.

  However, with the opening tab once separated and made swingable in a flap shape, it is substantially difficult to close the knife mouth. The connection part with the body is also weakened, and if the opening tab is separated from the lid body, it is difficult to notice the separated opening tab.

  Therefore, the present invention eliminates the problem of discarding the opening tab after opening the knife mouth, and further, the lid of a container such as a paste-like food in which the opening tab is not unintentionally separated from the lid, It is a first object to provide a container using this.

  Further, when the folded opening tab is made to be a flap and is present on the lid, it is conceivable that the portion cut off when the opening tab is folded is jagged. In this case, it may be possible to scratch the hand or the like due to carelessness of the user during use.

Therefore, in the present invention, such a freely-swinging opening tab is fixed, and further, the cut-off portion of the opening tab is prevented from coming into contact with the user, thereby further improving the safety of the pasty food, etc. It is a second subject to provide a container lid and a container using the same

  In order to solve at least one of the above problems, the present invention provides a lid configured to hold a folded open tab.

  That is, according to the present invention, a lid of a container containing butter, margarine, peanut butter, jam, marmalade and spread cheese, a highly viscous liquid food, or a granular or powdery food, which is brittle A container having an opening tab that allows a knife mouth to appear by separating and folding the portion formed on the container, and a locking means for holding the folded opening tab is formed in a region where the folded opening tab contacts The lid is provided to solve at least one of the above problems.

  The lid of a container (food container) that contains food such as a paste is often formed using a synthetic resin material, but is not limited thereto, and may be formed using various materials. it can. Moreover, the said cover body can also be formed with a material different from a container main body.

  The opening tab is a part for making a butter knife and a knife mouth for penetrating the handle part of the spoon appear. This is a weak part that forms part of the side of the lid as a perforation or thin part. By incising from the part, it can be defined as a region that becomes a flap shape (region that becomes an opening tab). Therefore, it is necessary that at least a part of the opening tab is connected to the lid, and the opening tab may be connected to the lid by a line or a point. Further, the flap-shaped opening tab may swing in any direction, and may be provided so as to swing in the horizontal direction in addition to swinging in the vertical direction of the lid.

  And the latching means which hold | maintains this opening tab is provided in the area | region where this opening tab was folded in the shape of a flap. Such a locking means can be formed as a structural part such as a protrusion or groove that holds the folded opening tab, or can be formed so as to be held by a material such as an adhesive or an adhesive sheet.

In the lid for foods such as a paste formed as described above, the knife mouth (not limited to a butter knife, including an opening for passing a spoon handle, etc., the same applies hereinafter) is opened. By holding the tab, it is possible to eliminate free swinging of the opening tab and to prevent the bent portion from being weakened. Thereby, the possibility that the unsealing tab unintentionally detaches from the lid can be eliminated.
Furthermore, it is no longer necessary to separate the flap-shaped opening tab in order to keep the knife mouth open, and the problem that small pieces generated when the knife mouth is intentionally separated becomes new garbage is also solved by the present invention, and the garbage is discarded. Save time and effort.
When the conventional knife mouth is used without being cut off, the tip of the partially cut knife mouth plastic (that is, flap-shaped opening tab) that moves around the fragile portion is the operator's hand. There are also potential problems such as being caught on clothes and clothes, but this can also be solved by the present invention.

  Further, the lid for a food product such as a paste according to the present invention includes a flat portion facing the opening of the container body, a bent portion that bends downward from the periphery of the flat portion, and a lower portion from the bent portion. And a strip-shaped portion covering the outside of the edge portion of the opening in the container body, and the unsealing tab extends between the two thin portions extending across the width direction of the strip-shaped portion. And a protrusion projecting in a direction intersecting the belt-like portion is formed at the tip of the opening tab, and the locking means is a groove into which the protrusion of the opening tab is fitted, or the protrusion It is desirable to form as the convex part which latches.

  In the lid body configured as described above, the band-shaped portion corresponds to the side surface of the lid body described above, and an opening tab is formed in a part of this portion. And the weak part is formed so that an opening tab can be easily caused. In addition, the distal end side of this unsealing tab, that is, the portion connected to the lid body for swinging is the base end, and the distal end side thereof intersects with the belt-like portion, for example, toward the inside or outside of the lid body. To form a protruding part. And the groove | channel which the projection part of an opening tab fits in, or the convex part which the said projection part latches is formed in the area | region which the folded back opening tab contacts, and hold | maintains the folded opening tab.

  By forming the locking means as a groove or a protrusion in this manner, the opening tab can be simply held up to the locking means, and the opening tab can be held and fixed smoothly and easily.

  Further, in the lid for foods such as the paste according to the present invention, the protruding portion is formed as a portion protruding in a flange shape toward the outside of the lid over the entire width direction of the opening tab, Preferably, the locking means is formed on the outer surface of the lid, and the unsealing tab is formed to be folded outward.

  It is because the opening tab can be more reliably held by forming the protruding portion over the entire width direction of the opening tab. In addition, by forming the protruding portion of the opening tab as a portion protruding in a flange shape toward the outside of the lid, and forming the locking means on the outer surface of the lid, the opening tab that is folded back to open the knife mouth , The outer side of the lid, that is, the outer side of the container, can be folded back, whereby the opening tab can be more reliably prevented from being mixed into the container.

  Moreover, the lid for foodstuffs such as a paste according to the present invention has a flat portion facing the opening of the container body, a bent portion that bends downward from the periphery of the flat portion, and a downward extending from the bent portion. And the bent portion is formed in a curved shape that curves from the flat surface portion to the belt-like portion, and the folded region of the opening tab in the bent portion. In addition, it is desirable to provide a groove-like accommodation portion in which the folded opening tab is accommodated.

  Such a groove-shaped receiving portion should be formed in a state where it is recessed from at least another portion, and should be sized and deep enough to receive the folded opening tab. And by providing such a groove-shaped accommodation part, the folded opening tab is accommodated in the groove-shaped accommodation part, and the part separated from the side surface (band-shaped part) of the lid body is not exposed. Thereby, problems, such as scratching a hand at the separated part, can be solved.

  And the groove-like accommodation part formed in the bent part is changed from the flat part to the belt-like part so that the problem of scratching by the folded opening tab is solved, and the opening tab that is folded and held is not raised by an external force. It is desirable that the length in the direction of the head is longer than the folded opening tab, and the depth is such that the folded opening and accommodated opening tab does not protrude. Thereby, the opening tab accommodated in the groove-shaped accommodation portion is not pushed back by other external force, and the holding thereof can be maintained for a long time and surely.

  In the lid of the present invention used in the paste-like / high-viscosity liquid / granular / powder food container, the locking means is any part of the lid and can hold at least the folded opening tab. It suffices if it is formed at a place, and the opening tab only needs to be formed at any one or more of the side surfaces of the lid.

  In order to solve at least one of the above-mentioned problems, the present invention provides a pasty food, a high-viscosity liquid food, or a container for granular or powdery food that is configured using the lid. That is, a container main body having an opening and containing a paste-like food containing butter, margarine, peanut butter, jam, marmalade and spread cheese, a highly viscous liquid food, or a granular or powdery food, and the container main body A lid that closes the opening of the container, wherein the lid is provided with the opening tab locking means according to the present invention, and the opening tab in the opening of the container body. It is a container for foodstuffs, such as a paste shape, in which a notch part which forms a knife mouth is formed in a portion facing to.

  In such a food container such as a paste, the cutout formed in the opening of the container body is preferably at least one or more, for example, when it is formed in a rectangular parallelepiped, a cube or other box shape. Can be formed in one symmetrical position on opposite sides where the openings are present.
