Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a plastic container with a lid for containing food and medicine, and in particular to a safety container that can be identified in the event that a foreign substance such as a poisonous substance is mixed in from the outside.

(Prior Art) Plastic safety containers for storing foods such as ice cream and lactic acid drinks or medicines are known from Japanese Utility Model Application Publication No. 1748/1983 as shown in Figures 9 and 10. In this known example, a claw part b is provided around the mouth edge of a container body a made of plastic, an outward facing flange plate c is provided below the claw part b, and a part of the outward facing flange plate c is connected to gaps d, d, A fitting groove e is formed on the small pieces c′ and c′ through the small pieces c′ and c′, and a fitting groove e is provided around the inner side of the outward facing flange plate c including the small pieces c′ and c′. g is provided so that it can be fitted into and removed from the fitting groove e, and a pawl locking portion h formed on the peripheral side plate g is provided so that it can be freely engaged and removed from the pawl portion b. Then, the small piece c' is bent downward or broken off, and the lower edge of the circumferential plate g is turned up at that point to remove the claw locking portion h from the claw portion b, and the lid is opened.

(Problem to be solved by the invention) In the above-mentioned known example, if the small piece c' is broken off, the container cannot be put back into its original state, and it is obvious that someone has opened the lid, and foreign substances such as poisonous substances can be detected. It can be seen that the plastic was mixed in, but the small piece of plastic
c' is not always broken off, and the lid may be opened in a bent state as described above, and if a foreign substance such as a poison is mixed in and the lid is then closed, the appearance of the container will be close to restored to its original state. Become. In addition, after bending the small piece c', the general purchaser also opens the lid by flipping up the lower edge of the circumferential plate g at that point.
Since the engagement distance L between the claw locking parts h other than the small pieces c' and c' and the claw part b is long, the engagement force is large, and a large force is required to open the lid. Especially when closing a large container, it is quite difficult to quickly and completely engage the pawl locking portion h and the pawl portion over a long distance.

(Means for solving the problems) This idea solves these inconveniences.
That is, a container body 3 made of plastic with an outward facing flange plate 2 disposed above the bottomed cylinder 1, a circumferential side plate 5 facing downward to the lid plate 4, and an outward facing flange plate 2 formed on the inner circumferential surface of the circumferential side plate 5. A fitting groove 6 is formed on the flange plate 2 to be removably fitted on the outside, and a plurality of cut-out linear portions 7,
7, 7, . . . formed at intervals, and a lid 8 made of plastic whose lower end extends to the lower edge of the peripheral side plate 5.

(Example) The example is a container for food such as ice cream, which consists of a container body 3 made of polyethylene or polypropylene and a lid 8 made of the same material. The container body 3 is made up of a bottomed cylinder 1 and an outwardly facing flange plate 2 integrally disposed above the cylinder 1. On the other hand, a rising portion 9 having a U-shaped cross section is integrally provided around the periphery of the lid plate 4.
A circumferential side plate 5 is integrally provided around the circumferential side plate 5, and a fitting groove 6 is provided in the inward facing surface of the circumferential side plate 5 as shown in FIGS. 1, 3, 5, and 6 to form the lid plate 4. The circumferential side plate 5 has different shapes at the X, Y, and Z sections in FIG. 2, with the X section having a thick tapered shape as shown in FIG. There is no part indicated by a broken line, and as shown in FIG. 3, the upper side 50 of the outward facing surface of the peripheral side plate 5 is formed vertically, the lower side 51 is formed tapered, and the vicinity 52 of the fitting groove 6 is formed thin, As shown in FIG. 4, the Z section has the outer surface of the circumferential plate 5 formed vertically, and the inward surface below the fitting groove 6 is formed vertically, from the fitting groove 6 to the lower end line 5' of the circumferential plate 5. This is made thinner and cut out to form a linear portion 7. In this embodiment, the wall thickness of the vicinity 52 and the cut line portion 7 is set to 0.3 mm to 0.5 mm, and the other thick portions are formed to be 2 to 5 times thicker than the neighborhood 52 and the cut line portion 7. Note that the cutout linear portions 7 are made equal to the thin wall as described above, and the cutout linear portions 7, 7, 7...
Any means that can be broken when bending the X and Y portions, which will be described later, may be used, such as making perforations as shown by broken lines 70 in FIG. 6. Moreover, the cutout linear portion 7 is the second
As shown in Z in the figure and in FIGS. 6 and 7, a large number of them are formed, and also a large number of Y parts and one X part are formed. Note that the reason why the X section was formed is to make the lid 8 more robust since if only the Y and Z sections were used, the strength of the lid 8 would be low. Then, ice cream or the like is stored in the container body 3,
The fitting groove 6 is externally fitted onto the outward facing flange plate 2, the lid is closed, and the product is placed at a store.

In the above state, in order for someone to mix a foreign substance such as a poisonous substance into the container body 3, as shown in FIG. The fitting groove 6 is removed from the outward facing flange plate 2 by bending it, and the lower side 51 is further turned up in the same direction. Here, as shown in Fig. 7, the Y part that is turned up is thick, and the Z and Z parts connected to it are thin, so the Z and Z parts, that is, the cutout linear parts 7, are sure to be cut out. be cut out. Even if you forcefully bend the X part, the Z and Z parts will always be cut off. Therefore, after opening the lid, someone may have mixed in a foreign substance such as a poisonous substance, and even if the lid is then closed, the cutout lines 7, 7 will always be cut and will not return to their original state. can immediately see abnormal situations.

Incidentally, the general purchaser successively bends and flips up all the Y parts as shown in the third diagram, and after cutting all the cutout linear parts 7, 7, 7...
Since the lid opens, the lid can be opened easily with a small amount of force. Conversely, when closing the lid during use or after use to reuse the container, the bent X part, Since the Y, Y, Y... portions are pressed down one after another to fit the respective fitting grooves 6 onto the outward facing flange plate 2, the lid can be quickly and easily closed with a small force.

(Effects of the invention) This invention forms a plurality of cut-out linear parts on the circumferential side plate of the lid at intervals, and also extends the lower end of the cut-out line parts to the lower edge of the circumferential side plate, so when opening the lid, the circumference No matter which part of the side plate is bent, the cutout line will always be cut out, and even if the lid is closed after foreign substances such as poisonous substances have entered, there will always be traces of opening the lid, making it safe. First, since the entire circumference can be opened and closed in parts one after another, even in the case of a large container, the lid can be opened and closed easily and quickly with a small amount of force.
