(First embodiment)
A foam container according to a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows the configuration of a foam container. FIG. 2 shows the foamed container in a state used for containing asparagus. The foaming container 1 includes a container main body 2 that stores an asparagus 100 or the like, a lid member 3 that is attached to an opening provided in the container main body 2, and the like. A slope 21 is formed on the inner surface of the bottom wall and the side wall of the container body 2 so as to correspond to the shape of the asparagus 100 having a narrow tip as required.

  3 to 7 show the structure of the lid member 3. An inclined surface 32 is formed on the wall portion 31 of the lid member 3 so as to protrude inward from the inner surface. The inclined surface 32 is formed with a contact portion 33 that contacts the asparagus 100 and an elastic portion 34 that biases the contact portion 33 inward. The contact portion 33 protrudes inward from the inner surface of the inclined surface 32 and is continuously formed integrally with the elastic portion 34. The elastic part 34 is formed on the base end side of the contact part 33. When the contact part 33 contacts the asparagus 100, the elastic part 34 is elastically deformed like a leaf spring and biases the contact part 33 inward. . The urging force of the elastic portion 34 can be appropriately set according to the thickness dimension of the elastic portion 34. Moreover, you may provide the recessed part for adjusting urging | biasing force on the outer side of the elastic part 34 as needed. This recess will be described in detail in the second embodiment.

  The slope 32 and the contact portion 33 of the wall portion 31 are integrally formed via a thin portion 35 (see FIGS. 5 and 8A) that is thinner than the elastic portion 34. The thin portion 35 is formed, for example, by providing a slight gap between the female mold for molding the lid member 3 and the male mold. When the asparagus 100 is packed, that is, when the asparagus 100 is accommodated in the container body 2 and the lid member 3 is attached to the container body 2, the contact portion 33 is pressed outward by the asparagus 100, The thin portion 35 is set to a thickness that can be broken. When the thin portion 35 is broken, the contact portion 33 can be moved outward. As the contact portion 33 moves outward, the elastic portion 34 is deformed and biases the contact portion 33 at the tip inward, that is, in the direction of the asparagus 100. Thereby, the contact state of the contact part 33 and the asparagus 100 is maintained. Moreover, when the contact part 33 moves outward, the edge 33a of the contact part 33 contacts the edge 32a of the slope 32, and the airtightness of the container is ensured. The thin portions 35 located at both ends of the contact portion 33 are formed by slits 36 formed on the outer surface of the lid member 3. The slit 36 is formed by a protrusion provided on the female mold. Instead of the slit 36, a slit may be formed on the inner surface of the lid member 3 by a protrusion provided in the male mold.

  FIG. 8 shows the periphery of the tip of the contact portion 33 in an enlarged manner. On the end edge 33a of the contact portion 33, a convex portion 33b is formed along the end edge 33a. A groove-like recess 32 b corresponding to the protrusion 33 b is formed at the edge 32 a of the slope 32. The protruding dimension of the convex part 33b is set to be equal to or slightly larger than the depth dimension of the concave part 32b so that the convex part 33b and the concave part 32b can be fitted. FIG. 8A shows the periphery of the tip of the abutting portion 33 before the lid member 3 is attached to the container body 2. Before the cover member 3 is mounted, the inclined surface 32 and the contact portion 33 of the wall portion 31 are integrally formed via the thin portion 35. As already described, when the lid member 3 is attached to the container main body 2 in which the asparagus 100 is accommodated, the contact portion 33 is pressed outward by the asparagus 100. Thereby, the thin portion 35 is broken as shown in FIG. 8B, the contact portion 33 and the inclined surface 32 are separated around the tip of the contact portion 33, the contact portion 33 moves outward, The convex part 33b fits into the concave part 32b. Thereby, the airtightness of the container is further ensured. In addition, the recessed part 32b is formed in the wide shape in the moving direction of the convex part 33b so that the movement of the convex part 33b may not be inhibited. Further, a convex portion may be formed on the end edge 32 a of the inclined surface 32, and a concave portion may be formed on the end edge 33 a of the contact portion 33. The convex portion 33b and the concave portion 32b will be described in further detail in the second embodiment.

  9 and 10 show the foamed container in a state where asparagus is accommodated. 9 and 10, unlike FIG. 2, the container body is arranged on the right side and the lid member is arranged on the left side. Moreover, the container main body 2 and a part of the lid member 3 are broken so that the asparagus can be confirmed. 9 and 10, it can be confirmed that the vicinity of the tip of the stem of asparagus is sufficiently held by the contact portion.

  As described above, according to the foam container of the present embodiment, when the abutting portion 33 is brought into contact with the container, the elastic portion 34 is elastically deformed in accordance with the shape of the container, so that the inside of the abutting portion 33 is formed. Therefore, a large gap does not occur between the contact portion 33 and the stored item. Thereby, even if it is a case where the foaming container 1 is set in the standing posture at the time of shipment and transportation, the contents can be sufficiently held. For example, when the foam container 1 is used to contain the asparagus 100, no gap is generated in the vicinity of the tip of the asparagus 100 regardless of the degree of growth of the asparagus 100. The vicinity of the tip portion of 100 can be sufficiently retained.

  Moreover, since the wall part 31 and the contact part 33 are integrally formed through the thin part 35, the contact part 33 can be formed easily. For example, when molding a foam container with a mold, a thin part is formed by a resin flowing into a minute gap generated on the mating surface of the female mold and the male mold, and the wall part and the contact part are formed. can do. Further, when the thin portion 35 is broken at the time of packing, the abutting portion 33 can be moved outward, and the elastic portion 34 can function. Further, since the thin-walled portion 35 after the breakage remains on the wall portion 31 and the contact portion 33, the airtightness inside the container can be ensured even when the elastic portion 34 is deformed. Moreover, the airtightness inside a container can be improved by fitting with the convex part 33b and the recessed part 32b. Since the contact portion 33 is formed so as to protrude further inward from the inclined surface 32, the contact portion 33 can be positioned more inward. Thereby, the design freedom degree of the contact part 33 can be raised according to the shape of things, such as asparagus 100 with a thin front-end | tip. By forming the contact portion 33, the elastic portion 34, and the like on the lid member 3, it is possible to implement a foamed container that can sufficiently hold the contents during shipment and transportation while using the conventional container body. . Moreover, since the thin part 35 currently formed in the cover member 3 is fractured | ruptured by mounting | wearing with the cover member 3, and the elastic part 34 can be functioned, the handling of the foam container 1 becomes easy.

(Second Embodiment)
11 and 12 show the configuration of the foam container according to the second embodiment of the present invention. This foamed container 10 is foamed in that concave handle portions 22 and 38 are formed on the container body 20 and the lid member 30 and a groove-shaped concave portion 37 is formed on the elastic part 34 of the lid member. Different from the container 1.

  The handle portion 38 is formed on the upper portion of the wall portion 31 of the lid member 30. The handle portion 22 is formed on the side wall of the container body 20 at a position facing the handle portion 38. The handle portions 22 and 38 may be formed to protrude outward from the container body 20 and the lid member 30.

  As described in paragraph (0024), the concave portion 37 is continuously formed in the width direction of the lid member 30 outside the elastic portion 34 in order to adjust the biasing force. That is, by forming the concave portion 37 in the elastic portion 34, the bending rigidity of the elastic portion 34 is reduced. The urging force of the elastic portion 34 can be optimized by appropriately changing the depth and position of the concave portion 37 according to the softness and mass of the object accommodated in the foam container 10.

  The convex portion 33 b is formed continuously in a straight line in the width direction of the lid member 30 along the edge 33 a of the contact portion 33. Similarly, the concave portion 32 b is continuously formed linearly in the width direction of the lid member 30 along the end edge 32 a of the wall portion 31 facing the end edge 33 a of the contact portion 33. When the lid member 30 is attached to the container body 20 containing the asparagus 100, the central portion 39 in the vicinity of the edge of the wall 31 shown by hatching in FIG. . When the central portion 39 is pressed inward, the wall portion 31 is bent and the concave portion 32b formed in a straight line is bent inward. On the other hand, since the contact portion 33 and the asparagus 100 are in contact with each other with the same pressure distribution in the width direction of the lid member 30, the shape of the convex portion 33 b is kept linear in the width direction of the lid member 30. Has been. Accordingly, the convex portion 33b and the concave portion 32b are sequentially fitted from the center portion to both ends, and as a result, the convex portion 33b gets over the corner of the inclined surface 32 (see FIG. 8) and fits with the concave portion 32b. Therefore, the force required for this is reduced, and the lid member 30 can be easily mounted.

  Further, when the foam container 30 in which the asparagus 100 is accommodated and the lid member 30 is mounted on the container body 20 is lifted, the handle portions 22 and 38 may be lifted upward with a finger or the like. At this time, since the stress applied to the handle portion 38 is distributed over the entire wall portion 31, the concave portion 32b is not curved upward, and the fitting state between the convex portion 33b and the concave portion 32b is firmly maintained. Is done. If the handle portion 38 is provided on the upper side of the lid member 30, the curvature of the concave portion 32b can be further suppressed.

  The present invention is not limited to the configuration of the above-described embodiment, and at least when the abutting portion 33 is abutted against the accommodation, the elastic portion 34 is elastically deformed according to the shape of the accommodation and the abutting portion 33. It is only necessary to be configured to urge the inward. Therefore, the contact part 33 and the elastic part 34 may be provided on the side wall or the bottom wall of the container body 2. The present invention can be modified in various ways. For example, the foam container 1 is not limited to storing food such as asparagus 100, and can be used for storing a wide variety of products. Further, the positions and shapes of the concave portion 37 and the handle portion 38 are not limited to those shown in FIGS.
