Description

  The present invention relates to a storage container used for food storage and the like.

For food storage containers such as polyethylene sealed containers that contain food, sealability is important to protect the contents.For example, these are provided with protrusions on the lid side wall and the container body peripheral wall. Increasing the fitting force of the lid by fitting the protrusion is performed (Patent Document 1). However, since it becomes difficult to open the lid, it is easy to open the lid by making the lid easily elastically deformed.

JP 2004-59055 A

However, when the container has a quadrangular shape, when an attempt is made to open the lid, an inward tensile force acts on both corners of the lid corner where the knob is provided. Since the protruding portion that is positioned is drawn inward and further bites into the lower end of the protruding portion that is positioned at the corner of the peripheral wall of the container body, there is a problem that the fitting force of the lid increases when the lid is opened.

The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a storage container that prevents an increase in the fitting force of the lid when the lid is opened.

In order to solve the above-mentioned problems, the present invention provides a fitting groove portion 6 having a lower surface opening on the peripheral edge portion of the top plate 2 of the quadrangular lid body 1 and fits the fitting groove portion to the peripheral wall 21 of the container body 20. In addition, the outer wall 5 of the fitting groove 6 in at least two opposing corners of the lid 1 is provided with a thin portion 8 that is elastically deformable and has a cross-sectional shape that is convex outward . It is characterized by that.

Further, according to the present invention, the fitting groove 6 is formed by an inner wall 3 rising from the periphery of the top plate 2 and an outer wall 5 depending from the upper end of the inner wall via an outward flange 4, and the container A first fitting protrusion 22 is provided around the outer surface of the upper part of the peripheral wall 21 of the main body, and the upper part of the fitting groove 6 is fitted to the first fitting protrusion 22, and the corner of the lid body 1 is fitted. A second fitting ridge 7 is formed on the inner surface of the outer wall 5 of the fitting groove portion 6 except for the second fitting ridge 7 to the lower end of the first fitting ridge 22 of the peripheral wall 21 of the container body. It is characterized by being engaged.

Further, according to the present invention, the thin portion 8 is provided on the outer wall 5 of the fitting groove portion 6 at the two opposite corner portions of the lid 1, and the remaining two corner portions not having the thin portion 8 are provided. One of them is provided with a knob.

Furthermore, the present invention is characterized in that the thin portion 8 is provided at three corners of the lid 1.

Further, the present invention is characterized in that the thin portion 8 is provided at four corners of the lid 1.

Furthermore, the present invention is characterized in that the thin portion 8 is formed in a triangular shape in a side view.

In the present invention, the thin portion 8 is provided at the corner portion of the lid, and the thin portion is elastically deformable and the cross-sectional shape is convex outward. Even if an inward tensile force acts on the top plate 2 due to the elastic deformation, the tensile force is reduced by the elastic deformation of the thin portion 8, so that an inward tensile force acts on the corner of the lid. However, the outer wall 5 of the fitting groove portion 6 of the lid body is elastically deformed inward and is prevented from being pressed against the first fitting protrusion 22 of the peripheral wall 21 of the container body. Is done.

  Further, according to the present invention, since the thin portion 8 is provided at the three corner portions of the lid, if the finger is placed on the lower end of the thin portion of the corner portion located in the middle and pulled outward, the thin portion is extended outward. Since it spreads, it is easy to insert a finger into the corner portion, and the thin-walled portion 8 can be used as a finger gripping portion in this way, so there is no need to project a knob portion protruding outward. Therefore, the knob does not get in the way when the container itself is stored.

  Further, in the present invention, since the thin portion 8 is provided at the four corners of the lid body 1, any thin portion 8 can be used as a knob when opening the lid, and therefore a specific knob is selected. In other words, when there are three thin-walled parts, the thin-walled part located in the middle must be selected, whereas in the case of four thin-walled parts, it is necessary to consider the selection of a specific thin-walled part when opening the lid. Therefore, it is easy to open the lid.

  Further, according to the present invention, the fitting groove 6 is provided on the peripheral edge of the top plate 2 of the lid, and the fitting groove is fitted to the peripheral wall 21 of the container main body.

It is a perspective view of the storage container which concerns on this invention. It is sectional drawing which follows the AA line of FIG. It is sectional drawing which follows the BB line of FIG. It is effect | action explanatory drawing which shows the state pulled with a finger | toe on the thin part. FIG. 5 is a perspective view of FIG. 4.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Reference numeral 1 denotes a lid, and the inner wall 3 is erected from the peripheral edge of the rectangular top plate 2 and the outer wall 5 is suspended from the upper end of the inner wall 3 via the outward flange 4, whereby the inner wall 3 and the outward flange 4 are suspended. And the outer wall 5 form a fitting groove 6. The fitting groove 6 is fitted to a first fitting protrusion 22 of the container body described later.

As shown in FIG. 3, the second fitting protrusion 7 is provided around the inner surface of the vertical intermediate portion of the outer wall 5 excluding the corner of the lid 1, and the corners 10, 11, 12, 13 of the lid 1 are provided. The thin-walled portion 8 that is elastically deformable is formed. The thin portion 8 is not particularly limited as long as the cross-sectional shape is outwardly convex, but is usually formed in a U shape, a V shape, a U shape, or the like. Moreover, it is preferable that the thin part 8 is a side view triangle shape in which a base is located below.

The number of the thin portions 8 is not particularly limited, but the thin portions 8 are intended to facilitate opening by extending in the circumferential direction when the lid 1 is opened. The interval between the thin portions 8 and the position of the upper end 8a of the thin portion 8 can be determined from the same viewpoint.

As described above, the thin portion 8 may be provided on all the four corner portions 10, 11, 12, 13 of the lid 1, or may be provided only on the three corner portions 10, 11, 12. In these cases, the thin-walled portion 8 located at one corner (for example, the corner 10) can be used to hang a finger when the lid is opened. In addition, when providing the thin part 8 only in the three corner | angular parts 10, 11, and 12, the corner | angular part 10 located in the center is utilized as a finger hook part. The number of the thin-walled portions 8 is not limited to the above, and the thin-walled portions 8 can be provided only at two opposite corners of the lid 1. In this case, a knob (not shown) is provided at one of the remaining two corners not having the thin portion 8.

  Reference numeral 20 denotes a container body, and a first fitting protrusion 22 is provided around the outer surface of the upper end portion of the peripheral wall 21. When the lid 1 is fitted to the container body 20, the upper part of the fitting groove 6 is fitted to the first fitting protrusion 22 and the second fitting protrusion 7 is first fitted as shown in FIG. It is fitted to the lower end of the mating ridge 22.

Next, the operation of this embodiment will be described.
