DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a synthetic resin container with a lid, and more specifically, a synthetic resin container with a good sealing property that can be opened by cutting off the lower edge of the lid. Regarding

(Prior Art) Generally, a synthetic resin container having a good hermetic sealing property is used as a container for storing food such as prepared foods. That is, this synthetic resin container is composed of a container and a lid that closes the open surface of the container, and this lid covers the entire periphery of the edge of the lid for the purpose of maintaining the hermetic sealing property of the container as described above. It is fitted in a container, and when the lid is opened, the notched portion of the lower edge of the lid is cut off over the entire circumference to release the fitted state, and then the lid is removed.

(Problems to be Solved by the Invention) However, when taking out the contents of the container in this synthetic resin container, the entire lid must be removed each time, and the work is very complicated. And when taking out the contents in the container, the entire lid is removed regardless of the amount, and opening the container every time it is used may cause contamination such as dust from the viewpoint of hygiene. Not desirable.

On the other hand, it is not possible to hold the removed lid by hand with it removed, and it is usually placed around the container.However, when the lid is attached to the container again, Since it is the surface that comes into direct contact with the contents, there is a risk of unsanitary conditions.

The present invention has been made in view of the above problems, and an object of the present invention is to open and close the lid when taking out the contents of the container without removing the entire lid from the container body. It is an object to provide a synthetic resin container capable of opening and closing the lid.

(Means for Solving the Problem) The present invention has been made to solve the above-mentioned problems by opening and closing a part of the lid with the lid still fitted in the container. .

That is, the present invention has an open-top container body 2 and an engaging protrusion formed on the outer peripheral surface of the upper part of the container body 2 having an edge 5a that can be fitted to the upper edge 2a of the container body 2. A lid body 4 having an engagement groove 13 capable of engaging with the container body 3 and fitted in the container body 2 in a hermetically sealed state, and the lid body 4 is provided with a bendable hinge portion 8. Moreover, the portion below the thin-walled cutting portion 14 on the inner surface side of the engagement groove 13 of the lid body 4 from one end side to the other end side of the hinge portion 8 is fitted in the hermetically sealed state of the container body 2 and the lid body 4. The fitting releasing piece 10 that can be detached is formed to be separable, and one side of the lid body 4 can be opened and closed with respect to the container body 2 via the hinge portion 8 by separating the fitting releasing piece 10. At the same time, the other side of the lid body 4 is attached to the fitting release piece 10 by fitting release preventing means provided at both ends of the hinge portion 8. It is a synthetic resin container having a structure in which separation is prevented and fitting in the container body 2 in a sealed state is maintained.

(Operation) In the synthetic resin container having the above configuration, the upper edge 2a of the container body 2 and the edge 5a of the lid 4 are fitted to each other, and the engaging projection 3 of the container body 2 and the lid 4 are By engaging with the engaging groove 13, the container body 2 and the lid body 4 are fitted in a sealed state, and the contents are sealed inside the container body 2 just like a conventional synthetic resin container. Be protected.

Next, when the contents are taken out from the synthetic resin container 1, the fitting release piece 10 around the lid body fitted to the container body 2 is separated from one end side to the other end side of the hinge portion 8. The fitting of the fitting releasing piece 10 to the container body 2 in a sealed state is released.

Then, since one side of the lid body 4 of which the fitting is released by the detachment of the fitting release piece 10 of the lid body 4 can be pivoted by the hinge portion 8 which is bendable, the hinge portion 8 is removed. Through this, one side of the lid 4 can be opened and closed.
At this time, since the fitting release preventing means as described above is provided at both ends of the hinge portion 8, the fitting release piece 10 is separated from the one end side to the other end side of the hinge portion 8 as described above. As a result, even if one side of the lid body 4 is openable and closable, the detachment of the fitting release piece 10 is blocked by the fitting release blocking means, and as a result, the other side of the lid body 4 is inserted through the hinge portion 8. On the side, by fitting the upper edge 2a and the edge 5a and engaging the engaging projection 3 and the lid engaging groove 13, the fitting in the container body 2 in a sealed state is maintained, It does not come off from the container body 2 carelessly.

Therefore, the synthetic resin container 1 can take out the contents in the container body 2 by opening and closing only one side of the lid body 4 without removing the entire lid unlike the conventional container.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1A and 1B, 1 indicates a synthetic resin container.

Reference numeral 2 denotes a container body formed to have an open upper surface, and a substantially wedge-shaped engaging projection 3 is provided on the upper edge portion 2a of the container body 2 in the outer peripheral direction. The projecting direction of 3 extends horizontally or slightly downward. This is because the engaging projection 3 can be easily engaged with an engaging groove 13 described later, and is designed so as not to be accidentally disengaged once engaged.

Reference numeral 4 denotes a lid body having a substantially rectangular shape in plan view, and an outer peripheral portion of the lid body 4 is formed with an edge portion 5a having a substantially inverted U-shaped cross section so as to fit with the upper edge portion 2a of the container body 2. A substantially V-shaped engaging groove 13 for engaging with the engaging projection 3 is formed in the lower portion of the portion 5a. Further, the engaging groove 13 is engraved to form a separable end portion 9 below the thin-walled cutting portion 14, and the end portion 9 is divided into a fitting release piece 10 and a remaining portion 11 by notches 6 to be described later. Will be done.

A hinge portion 8 which can be bent is formed at a predetermined position of the lid body 4, and substantially V-shaped notches 6 are formed at both ends of the hinge portion 8.

The present invention has the above-mentioned configuration, and a usage example thereof will be described below.

First, in FIG. 1 (a), the container body 2 and the lid 4 of the synthetic resin container 1 are fitted by the engagement of the engaging projections 3 and the engaging grooves 13 as shown in FIG. 1 (b). Become. In this state, the contents are sealed and there is no difference from the normal storage state of the container.

Next, when the contents are taken out from the container body 2, as shown in FIG. 2 (a), the end portion 9 of the lid body 4 is released in order to release the fitted state in order to open the lid body 4. The fitting release piece 10 which is a part of is cut off, but at this time, the fitting release piece 10 is cut off from the cutting portion 14,

That is, the fitting release piece 10 at the end portion 9 of the edge portion 5a is separated, and the remaining portion 11 is not separated and the fitting state is maintained.

At this time, the engagement between the engagement groove 13 of the lid body 4 and the engagement protrusion 3 of the container body 2 is released by the detachment of the fitting release piece 10 as shown in FIG. And the upper edge portion 2a is only fitted, and therefore one side of the lid body 4 is detachable from the container body 2.

The one side of the detachable lid body 4 is opened to the container body 2 by bending the hinge portion 8 of the lid body 4 as shown in FIG. Of. Since the notch 6 is formed in the edge portion 5a in the open state of the one side of the lid body 4, the opening / closing operation of the lid body 4 is not hindered.

When the lid 4 is opened, since only the one side of the lid 4 can be opened and closed, the remaining portion 11 of the edge portion 5a of the lid 4 remains attached to the one side of the lid 4 as described above. Since the contents of the container body 2 can be taken out by opening, the lid body 4 does not accidentally come off, and the contents can be taken out by opening one side of the lid body 4, as well as the opening and closing of the lid body 4. Also, since the hinge 8 is rotated about the hinge, it can be easily opened and closed.

In addition, in the above-mentioned embodiment, the notch 6,
By forming 6, the separation of the fitting release piece 10 is configured to be blocked by the notches 6 and 6, but the means for preventing the separation of the fitting release piece 10 is not limited to this. . The point is that such fitting release preventing means may be provided at both ends of the hinge portion 8.

Further, in the above embodiment, the container body 2, the lid body 4, the hinge portion 8,
The specific configuration, shape, etc. of the fitting release piece 10 are not limited.

In addition, the details of the present invention can be changed freely within the scope of the invention, and therefore the details of the specification change do not matter.

(Effect of the Invention) As described above, the present invention forms a hinge portion on the lid of a synthetic resin container, and separates the fitting release piece from one end side to the other end side of the hinge portion to remove the lid. Since the structure is such that the fitting on one side of the body can be released, it is possible to take out the contents without removing the entire lid as in the past.
The contents can be taken out by opening and closing only one side of the separated lid while the other side of the lid is still fitted, and the work of taking out the contents is remarkably easier than the conventional one. It came to have a very special effect.

Further, in the synthetic resin container of the present invention, even when the lid is opened, the lid is not accidentally detached because the sealing fit state is maintained at the remaining part of the edge of the lid. .
