  In a container with a lid as described above, hermeticity is important in order to protect the contents. Therefore, the lid is often designed so as to fit strongly to the outer peripheral portion of the container body.

  The lid is made of a material that is flexible and easily deformed in consideration of ease of opening, but it may be difficult to open depending on the shape of the container. This is because the opening of the container body has a corner portion, and the deformation causes biting into the corner portion of the container body, and a lid opening force larger than the fitting force planned at the time of design is required.

  Specifically, when opening the container of the above prior art, as shown by a white arrow in FIG. 8 (A) of the present application, one of the corners of the cover plate is picked up, and at this time, the cover plate is flexible. For this reason, a force acts in the direction of the black arrow on two corners adjacent to the picked corner. For this reason, the inner corner surface of this corner portion approaches the outer peripheral wall of the container body as indicated by an arrow in FIG. Since the lid is opened while rubbing the adjacent corners against this biting force, a large resistance is generated.

  In order to facilitate the opening of the lid, for example, a device has been proposed in which the base of a triangular portion including one corner of the lid is hinged to the remaining portion of the lid so as to be pivotable ( Patent Document 3). However, with this method, the sealing performance of the lid is lowered.

  A first object of the present invention is to provide a lidded container that can reduce resistance when a flexible lid is removed from the outer peripheral wall of the container.

  The second object of the present invention is to provide a container with a lid that can reduce resistance when a flexible lid is removed from the outer peripheral wall of the container and that does not impair the sealing performance.

The first means is
Standing up the outer peripheral wall 4 from the periphery of the bottom wall, a rectangular container body 2 as viewed from above,
A flexible lid 10 having a lid peripheral wall 14 suspended from the peripheral edge of the rectangular lid plate 12 corresponding to the container body and fitted to the upper end of the outer peripheral wall 4;
In at least two opposing corners of the lid body 10, a bulging portion 16 is formed in which the lower side of the lid peripheral wall 14 spreads outward, so that the gap between the inner surface of the bulging portion 16 and the corner outer surface of the outer peripheral wall 4 is increased. Is provided with a gap G.

  As shown in FIG. 1, this means is formed so that the peripheral wall of the lid bulges outward at the opposite corners of at least two lids, and a gap is formed between the bulging part and the upper end of the outer peripheral wall of the container body. It is proposed to provide G (see FIGS. 2 and 3). This gap G is an allowance for displacing inward without being pressed against the container body when the lid is opened. As shown in FIG. 5, since the lid peripheral wall rotates around a point O (rotation center) on the upper end side, it is preferable that the gap G is formed so as to increase toward the lower side (away from the point O). It is.

  The second means includes the first means, and the cover plate portion excluding the outer peripheral portion 12a is depressed to form a fitting groove 20 with the outer peripheral portion 12a and the cover peripheral wall 14, and the fitting groove. And at least the inner surface of the upper end portion of the outer peripheral wall are in airtight contact.

  In this means, as shown in FIG. 3, it is proposed that the cover plate part excluding the outer peripheral part is depressed in a step shape. This step is pressed against the outer peripheral wall by fitting the recessed portion of the cover plate into the outer peripheral wall, thereby forming a seal surface S.

  The third means includes the first means or the second means, and the bulging portion 16 is formed at all four corners of the lid.

  In this means, as shown in FIG. 6, the four corners are provided with bulging portions, so that any two corners of the lids can be removed from the outer periphery of the container body by pulling any of the corners and pulling them up. Can be detached from the wall. Since it is not necessary to confirm the position of the corner with the bulging portion, it is easy to use.

  The fourth means includes any one of the first means to the third means, and the lid peripheral wall 14 corresponds to the right side portion 15 corresponding to each side of the quadrangle and each corner of the quadrangle. It forms with the bulging part 16, and it forms so that it may fit in the opening part of a container body by pressing each right side part to the upper end part of the outer peripheral wall 4 of a container body.

  In this configuration, in the configuration shown in FIG. 1 or FIG. 6, the straight side portion of the cover peripheral wall is pressed against the outer peripheral wall, and the outer peripheral wall is tightened and fitted over the entire cover peripheral wall. For example, when the tapper container is dropped on the floor, a disadvantage such as the lid being removed is prevented.

  The fifth means is characterized in that the bulging portion also serves as a knob.

  According to the first aspect of the invention, since the bulging portion 16 in which the lower side of the lid peripheral wall 14 spreads outward is formed at the two opposing corners of the lid, the inner surface of the bulging portion and the outer periphery of the container body The lid 10 can be easily removed using the gap G between the walls 4 as a margin.

  According to the second aspect of the invention, the fitting part formed by the outer peripheral part 12a and the cover peripheral wall 14 is formed by sinking the cover plate part excluding the outer peripheral part 12a, and the inner surface of the upper end part of at least the outer peripheral wall of the container body. Since the contact is made airtight, the sealing performance of the lid is good.

  According to the invention relating to the third means, since the bulging portion 16 is formed at the front part of the four corners of the lid body, the lid body can be easily opened by picking any corner portion, and the sealing performance is improved. It is good.

  According to the fourth aspect of the invention, since the straight side portion 15 of the lid peripheral wall is pressed against the outer peripheral wall 4 of the container body, the fitting force is not impaired even if the bulging portion 16 is provided.

  According to the fifth aspect of the invention, the lid can be easily opened by grasping the bulging portion 16.

  This container with a lid is formed of a container body 2 and a lid body 10. Each component of the container can be formed of a synthetic resin unless otherwise specified.

  The container body 2 has a quadrangular shape (rectangular shape in the illustrated example) as viewed from above, and the outer peripheral wall 4 stands from the outer peripheral portion of the bottom wall. In the illustrated example, an outer rib 6 is provided around the outer surface of the outer peripheral wall 4, and the upper end surface of the outer peripheral wall is preferably formed on a flat horizontal surface.

  The lid body 10 includes a quadrangular lid plate 12 corresponding to the container body and a lid peripheral wall 14 that hangs short from the outer edge of the lid plate. The lid peripheral wall 14 has a function of maintaining the closed state of the lid body by fitting to the outer surface of the upper end portion of the outer peripheral wall 4. The lid body is formed of a relatively flexible material, and can be bent and deformed when the corner of the lid body is picked up and pulled up, and the lid peripheral wall 14 can be detached from the upper end of the outer peripheral wall 4. A locking projection (not shown) for locking to the lower surface of the outer rib 6 may be provided at the lower end of the peripheral wall portion of the lid other than the corner.

  Of the four corners of the lid body, the lid peripheral wall bulges outward at two corners that face each other in the diagonal direction. A gap G is formed between the inner surface of the bulging portion 16 and the outer surface of the upper end portion of the outer peripheral wall 4 of the container body.

  As shown in FIG. 3, the bulging portion 16 is at least a downward opening, and is preferably expanded toward the bottom. In the illustrated example shown in FIG. 3, the entire upper and lower direction of the lid peripheral wall does not bulge outward, but the upper end portion of the lid peripheral wall is pressed against the outer peripheral wall, and the lid peripheral wall portion excluding the upper end portion protrudes outward. Yes. This is to improve the sealing performance of the lid. Further, it is desirable that the two bulging portions 16 have the same shape.

  As shown in FIG. 2, the gap G extends along the outer surface of the corner of the outer peripheral wall 4 along the circumferential direction of the outer peripheral wall 4, and when the lid is opened, the inner surface of the bulging portion 16 is the outer wall. It is formed so as not to hit the outer surface. The gap G in the illustrated example has a crescent cross section.

  Of the four corners of the lid 10, two tongue-like tabs 17 project from two opposing corners having no bulge.

  A portion of the lid peripheral wall 14 excluding the bulging portion forms a straight side portion 15. Each straight side 15 is pressed against the outer peripheral wall 4 of the container body. In order to realize this function, the bulging portion 16 is provided with a certain degree of strength within a range that does not impair the deformability, and is provided so that the straight side portion 15 can be fastened to the outer peripheral wall 4.

  Moreover, the part except the outer peripheral part 12a of the said cover board 12 is depressed flat via the level | step difference 18, and the fitting groove | channel 20 is formed by the cover peripheral wall and the outer peripheral part 12a of a cover board. The inner surface and the upper surface of the fitting groove 20 form a seal surface S with the outer peripheral wall 4.

  In the above configuration, when the knob 17 is picked up and pulled up as shown in FIG. 5, the gaps G are provided at the adjacent corners so that the adjacent corners are detached without rubbing against the outer peripheral wall 4 of the container body. .

  Hereinafter, other embodiments of the present invention will be described. In these descriptions, the same components as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

  6 to 7 show a lidded container according to a second embodiment of the present invention.

  In this embodiment, the knob 17 of the previous embodiment is omitted, and the bulging portions 16 are provided at all four corners of the lid.

  The bulging portion 16 of the present embodiment also serves as a means (gap forming means) for facilitating detachment of the corners of the lid and a finger hooking portion. That is, when one of the four corners (the corner in front of the drawing in the example of FIG. 7) is picked and pulled up, two adjacent corners (the left and right corners in the example shown in the figure) , Both corners are detached without rubbing against the lid.

  The bulging portion 16 of this embodiment is formed in a structure that bulges outward from the outer peripheral wall of the container body to such an extent that it can be picked with a finger. The bulging portion of the previous embodiment does not necessarily have to be formed in such a structure, and the bulging portion bulges from the container body to such an extent that a gap is provided for the corner of the lid to be separated from the corner of the opening of the container. It's enough. However, the drawings are drawn in the same shape for convenience of drawing.

  According to the configuration of the present embodiment, since the bulging portions that are also used as finger hooks are formed at all the corner portions, there is no need to visually confirm the positions of the corner portions where the bulging portions are present.

  In addition, it is not necessary to change the orientation of the container body so that the bulging portion 16 is easy to operate, and since it can be operated from either (omnidirectionality of operation), handling is easy. In order to make the feeling of use uniform, it is desirable that all the bulging portions have the same structure and the same shape.
