  The present invention relates to a storage container such as a wooden box, and more particularly to a storage container in which a lid can be attached to an opening of a container body without using a fixing metal fitting such as a nail.

  Conventionally, when attaching a lid body such as an upper lid or a bottom lid to an opening of a container body, a fixing bracket such as a nail or a staple is often fixed. For example, Japanese Patent Laid-Open No. 10-24980 discloses a box-shaped container composed of a pair of side wall plates facing in parallel, another pair of side wall plates, and a bottom plate, and a rectangular opening of the container. A box-shaped container with a simple lid material is disclosed, which includes a covered sheet and a stop plate attached and fixed on the pair of side wall plates so as to face each other in parallel via the coated sheet (Patent Document 1). ).

  In addition, as an attachment method that does not use the fixing metal fitting, for example, in Utility Model Registration No. 3120697, a lateral groove is formed on the inner three surfaces slightly above the lower surface of the rectangular frame in plan view. A bottom plate that can be opened and closed by sliding in the lateral groove is fitted, and the bottom plate is attached to form a box shape, and the upper end surface of the box frame forms a step shape with the inside raised and the outside lowered A structure of a cherry blossom packaging box provided with a wooden lid that comes into close contact with the vertical surface where the step rises and fits to the lower surface on the outside is disclosed (Patent Document 2).

It is configured in a rectangular shape. The upper surface of the container body 2 is opened as a substantially rectangular opening 21. In the present embodiment, a thermosetting adhesive is applied to the joints between the side wall plates 22 and the bottom plate 23 and bonded to each other by applying a high frequency.

  The lid 3 closes the opening 21 of the container body 2 and is formed of a flexible material having substantially the same shape as the opening 21. In the present embodiment, the lid 3 is not limited to a so-called upper lid that closes the upper surface of the container body 2 or a so-called bottom lid that closes the bottom surface of the container body 2. Includes everything that plugs.

  As described above, in the present embodiment, as shown in FIGS. 1 to 3, the convex stepped portion 24 is provided at the upper end portion of each side wall plate 22. Insertion grooves 25 and 25 are formed in a pair of opposing inner wall surfaces of the convex stepped portions 24, respectively. These fitting grooves 25, 25 serve to hold the lid 3 from both sides, and are engraved in a shape that allows the end of the lid 3 to be fitted. In the present embodiment, the fitting grooves 25 and 25 are formed on the convex stepped portion 24, but the present invention is not limited to this configuration, and the inner wall surface opening end in the vicinity of the opening portion 21 of the side wall plate 22. What is necessary is just to be provided in the part. Moreover, in this embodiment, although the insertion groove | channel 25 is formed only in the side wall plates 22 and 22 which comprise a short side, it is not restricted to this structure, In the side wall plates 22 and 22 which comprise a long side, Only the fitting groove 25 may be formed, or the fitting groove 25 may be formed in all the side wall plates 22.

  Moreover, in this embodiment, each fitting groove 25 has the groove side taper surface 26 inclined toward the accommodation side from the opening side of the container main body 2, as shown in FIG.1 and FIG.3. On the other hand, a lid-side taper surface 31 having substantially the same inclination angle as the groove-side taper surface 26 is formed at the end of the lid 3 fitted in the fitting groove 25. However, the shapes of the fitting grooves 25 and the ends of the lid body 3 are intended to improve the ease of attaching and detaching the lid body 3 and the function of preventing the dropout, as will be described later. Therefore, it is not restricted to said structure, At least the insertion groove | channel 25 should just be formed in the accommodation side deeper than the opening side. Moreover, the edge part of the cover body 3 should just be formed in the shape which extended the inner surface side more outward than the outer surface side according to the shape of the fitting groove | channel 25. FIG.

  Further, in the present embodiment, as shown in FIGS. 1 to 3, an opening recess 27 for removing and opening the lid 3 is formed at the upper end portion of the side wall plate 22 having the fitting groove 25. . As shown in FIG. 3, the opening recess 27 is formed between the upper end of the side wall plate 22 and the inner surface of the lid 3 in the closed state where the lid 3 is fitted into the container body 2. A gap into which a removal tool for bending and removing can be inserted is formed.

  In the present embodiment, the gap is formed to have a width and height enough to insert a predetermined removal tool. Moreover, as a removal tool, a special instrument is not required, for example, the handle part of a spoon like a general household, a minus driver, etc. can be utilized. The opening recess 27 may be formed at any position as long as the lid 3 can be bent by the lever principle and removed, but the central upper end of the side wall plate 22 in which the fitting groove 25 is formed is More preferred. This is because it is more effective to give this principle in the vicinity of the fitting portion.

  In addition, in this embodiment, the cover body 3 is formed in the dimension which does not drop, when fitted in each fitting groove 25. Specifically, as shown in FIG. 2, the length L <b> 1 of the perpendicular drawn from the center point of the lid 3 to the outermost edge portion of the end portion fitted in the fitting groove 25 is convex from the center point of the opening 21. It is formed longer than the length L2 of the perpendicular line dropped on the innermost edge of the stepped portion 24. As a result, the lid 3 fitted in each fitting groove 25 is not easily removed by a force that is inadvertently applied during transport or the like.

  Moreover, in this embodiment, in order to improve the airtightness of the storage container 1, as shown in FIG. 2, the length L3 of the perpendicular line dropped from the center point of the lid 3 to the end portion not fitted into the fitting groove 25; The length L4 of the perpendicular line dropped from the center point of the opening 21 to the inner wall surface of the convex stepped portion 24 without the fitting groove 25 is formed to have substantially the same length.

  Next, the operation of the storage container 1 of this embodiment will be described with reference to the drawings.

  First, in the storage container 1 of the present embodiment, when the lid 3 is attached to the opening 21 of the container main body 2, predetermined contents are stored in the container main body 2. Then, as shown in FIG. 4A, one end portion of the lid body 3 having the lid-side tapered surface 31 is fitted into one of the fitting grooves 25 and brought into contact therewith. At this time, in this embodiment, since the fitting groove 25 is provided in the convex stepped portion 24, the upper surface of the side wall plate 22 plays a role of guiding the lid body 3, and the lid body 3 is positioned in the fitting groove 25. Easy to match.

  Next, as shown in FIG. 4B, the other end of the lid 3 having the lid-side tapered surface 31 is fitted into the other of the fitting groove 25 while the flexible lid 3 is bent. At this time, since the groove-side tapered surface 26 of the fitting groove 25 is slightly slid while guiding the lid-side tapered surface 31 of the lid body 3, it is easy to fit. The fitting method is not limited to this method, and the lid body 3 may be bent and fitted by pressing the upper surface of the lid body 3 downward.

  Then, as shown in FIG. 4 (c), after the lid 3 is fitted into the fitting groove 25, the fitting grooves 25 arranged so as to oppose each other hold the both ends of the lid 3, and the drop off is prevented. To prevent. For this reason, if it is not especially heavy like udon etc., it can be used for the bottom lid.

  Further, in the present embodiment, between the container body 2 and the lid 3, the lid-side tapered surface 31 is substantially in close contact with the groove-side tapered surface 26, and the other end of the lid 3 is a convex stepped portion 24. Nearly close. For this reason, the contents are prevented from popping out and dust and the like are prevented from entering.

  On the other hand, in this embodiment, when removing the lid 3 from the opening 21 of the container main body 2, a removal tool such as a spoon handle or a minus driver is inserted into the opening recess 27. Then, when the base end portion of the removal tool is pushed down by the lever principle with the opening concave portion 27 as a fulcrum, the tip end portion applies an upward force to the lower surface of the lid 3. Accordingly, the lid 3 is appropriately bent, and the lid-side tapered surface 31 slides along the groove-side tapered surface 26 so that the lid 3 can be removed with a relatively light force.

According to the storage container 1 of the present embodiment as described above,

For example, the shape of the opening 21 and the lid 3 may be a polygonal shape such as a pentagon or a hexagon, and each side wall plate 22 may be an arc. However, in any case, the fitting grooves 25 may be formed in at least two opposing side wall plates 22.

  In the present embodiment, “opposing” means not only the parallel facing position state but also the side wall in the arrangement relation in consideration of the arrangement of the minimum fitting grooves 25 that can hold the lid 3. The position state of the plate 22 is included.

  For example, in the case of a pentagon as shown in FIG. 5, the side wall plate 22 is not in a parallel facing relationship. However, if the fitting groove 25 is provided on the side F1, the fitting groove 25 is at least on the side F3 or the side F4. May be formed. In addition, in the case of a hexagon as shown in FIG. 6, if the fitting groove 25 is provided on the side S1, the fitting groove 25 is formed on the side S3 or the side S5 as well as the side S4 in the parallel facing relationship. Alternatively, it may be formed on three sides.

  Further, as shown in FIG. 7, even if two of the four side wall plates 22 are formed in an arc shape, if the fitting grooves 25 are formed in the flat side wall plates 22 facing each other, as shown in FIG. The fitting groove 25 may be formed in the side wall plate 22 if necessary. Furthermore, even if the side wall plate 22 is formed in a circular shape as shown in FIG. 8, the fitting groove 25 may be formed at an opposing position where the lid body 3 can be held.

  If necessary, the fitting grooves 25 may be formed on all the side wall plates 22 or on the entire circumference of the side wall plates 22. Accordingly, all the side wall plates 22 can be obtained simply by cutting the plate material provided with the fitting grooves 25 without considering the presence or absence of the fitting grooves 25 into the side wall plates 22 having a predetermined width shape or by transforming them into a circular shape. Is produced. For this reason, a manufacturing process can be unified and manufacturing cost can be reduced.

  Moreover, in this embodiment mentioned above, although the fitting groove | channel 25 is provided along the upper end part of the side wall board 22, it is not restricted to this structure, As shown to FIG. 9 and FIG. You may make it form a predetermined length apart from the upper end surface of this. Thereby, since the angle of the corner | angular part of the insertion groove | channel 25 becomes an obtuse angle, it prevents that a burr | flash generate | occur | produces when forming the insertion groove | channel 25, or prevents damage when attaching / detaching the cover body 3. be able to. Further, the shape of the fitting groove 25 is not limited to an acute shape having a tapered surface, and the generation of burrs can be further reduced if it is formed in an arc shape having a curved surface. In this case, the end portion for fitting the lid 3 may be formed in an arc shape.

  Further, in the present embodiment described above, the fitting structure of the lid 3 and the fitting groove 25 is applied only to the opening 21 on the upper surface side of the container main body 2, but is not limited to this configuration. The fitting grooves 25 may be formed on both the upper surface side and the bottom surface side, and the lid body 3 may be fitted into both the opening portions 21.
