Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sealed container with a plastic lid-opening prevention device that is used to pack processed foods such as seafood and wild plants and sell them safely so that they cannot be opened halfway.
[0002]
[Prior art]
The closed container with a lid-opening prevention device is equipped with a lid-opening prevention device that locks the lid in order to ensure food safety so that it cannot be opened by others in the distribution mechanism up to the consumer. Since the lid opening prevention function is lost, the lid opening is performed without any trouble. Examples thereof include those proposed in Japanese Patent Application No. 7-113958 (Japanese Patent Laid-Open No. 7-113958) related to the applicant.
[0003]
FIG. 5 shows an essential part thereof. According to the sealed container, an attached edge piece 34 having an inverted U-shaped cross section is provided on the peripheral edge of the lid 33, and this is an upright edge of the upper end of the body 32. 36, when opening the lid, it is necessary to raise the lower end of the outer edge of the attached edge piece 34 with a finger, while the body has an annular protrusion 38 on the outer peripheral surface. , And an edge drop groove 40 in which the lower end of the attached edge piece 34 falls is formed thereon so that the annular protrusion 38 becomes an obstacle to lifting the attached edge piece 34. Met. Then, in order to remove the obstacle when the lid is first opened, a cut groove 42 is formed at the projecting proximal end of the ring-shaped protruding piece 38, and the ring-shaped protruding piece along the cut-out groove is formed by a knob 43 suspended in part. Can be cut off.
[0004]
[Problems to be solved by the invention]
According to the conventional closed container with a lid-opening prevention device as described above, the presence of the annular protruding piece ensures a locked state where the lid cannot be opened, and at the same time guarantees unopened safety. On the other hand, in order to ensure watertightness, an overhanging portion 44 is provided on the outer periphery of the standing edge of the body, and a guide slope 46 is provided on the inner periphery at an angle that resists lifting of the lid so that juice does not come out. The parts 44 and 46 were tightly coupled.
[0005]
However, in such a close contact structure, the attached edge piece 34 is formed on the lid, and thus the lid has a wide recess 48. The recess 48 has some reason such as condensation during use. Water may accumulate due to leakage of juice from other containers, and there is a disadvantage that if a label is attached to the bottom surface of the container, it may cause peeling.
[0006]
Further, since the knob 43 is suspended, the knob operation for removing the annular protrusion 38 is not easy, and the lid can be easily opened and closed because of the coupling at the projecting portion 44 and the guide slope 46 even after opening. It wasn't.
[0007]
In view of the above situation, the present invention eliminates a deep recess where water accumulates on the upper surface of the lid, and is easy to open and open / close even after opening. An object of the present invention is to provide an airtight container with a prevention device.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a body made of a soft or semi-rigid plastic having a deep channel portion that opens narrowly upward in the mouth wall, an outer peripheral wall inserted into the channel portion, It consists of a hard plastic lid with an inner peripheral ridge that is inserted in close contact with the inside of the mouth wall, and is extended from the outer peripheral wall of the main body upper wall. There is a hook part to be used as a finger hook to open the lid, and a high height surface is formed by a step near the periphery, and a shallow groove that can be threaded on the height surface is provided in an annular shape. The body is formed in a close-fitting shape with the outer periphery of the channel portion as a band wound piece with respect to the outer wall of the lid, and is joined to the outer peripheral wall by unevenness, and the upper surface of the band wound piece is hooked on the collar To make contact impossible On the other hand, it is formed so that it can be cut off at the lower end of the channel part so that the uneven connection with the outer peripheral wall of the lid can be released, and in addition, for the cutting, a knob is provided with a cut portion on a part of the band wound piece, An airtight container with a lid-opening prevention device, which is formed at an inclination angle that opens the knob outward, is configured.
[0009]
[Action]
According to the above configuration, when the lid is put after food is stuffed into the body, the outer peripheral wall of the lid is inserted into the channel portion of the body against the mutual irregularities, but the lid cannot be easily removed due to the irregularities. It becomes locked. To release the locked state, cut the strip from the cut edge by picking. In this case, since the uneven connection is eliminated, the lid can be easily opened and closed thereafter.
[0010]
In addition , since the step on the high surface acts as a rib on the top wall of the main body of the lid, the locked state is stable and the lid can be easily opened and closed. In addition, since the knob is formed with an inclination to the outside, the opening operation can be performed while picking it easily.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
In the present invention, the shape of the container in the drawing is a shape close to a rectangle in the drawing. However, the shape of the container may be a shape close to an ellipse with each side of the rectangle projecting outward, or may be a circle or an ellipse. Good. Since it has an inner circumferential ridge 14 provided on the lid 2, even after opening, tightness of juice from leaking is ensured.
[0012]
The inner peripheral ridge 14 and the step 15 ensure the lid opening prevention device 3. In addition, since the lid 2 has a wide height surface 17 due to the step 15, there is no inconvenience that water accumulates on the lid 2, and the yarn bottom 10 of the upper container can be hung on the shallow groove 18 and stably stacked. it can. In addition, a notch groove 22 is provided in order to cut out the strip 11 that is the main body of the lid opening prevention device. However, the cut-out portion may be a chain line contact or the like. The inclination of the knob 25 is an angle that warps, for example, 30 degrees or 40 degrees with respect to the vertical.
[0013]
The lid opening preventing device is configured by joining the band-wound piece 11 of the body 1 and the outer peripheral wall 13 of the lid 2 by unevenness, but the unevenness is not particularly limited as long as the shape is along the outer periphery. In the figure, the concave grooves 19 and the convex protrusions 20 are simply valley-shaped or mountain-shaped, but they are variously formed as long as they are tightly coupled so that the juice does not leak and the lid 2 cannot be opened illegally. be able to. For example, a shape that is non-returnable in the upward direction in which the juice goes out can be considered.
[0014]
【The invention's effect】
As described above, according to the present invention, it is possible to safely distribute the product until it is opened by the consumer without fear of being opened illegally, and the lid can be easily opened and closed after opening. In addition, since the lid is not provided with a recess in order to adopt such a structure, there is no inconvenience that water accumulates on the upper surface of the lid, and the handle for opening is inclined so that it can be opened easily. There is an excellent effect of being able to.
