Description

  The present invention relates to a food container that can store and hold food as a stored item.

Conventionally, as a tray for cakes or the like, there is a tray composed of a tray main body having a bottom surface and a peripheral surface, and a knob integrally formed on the outer peripheral portion thereof. This knob is in a posture substantially perpendicular to the bottom wall, has an open bottom surface and is hollow inside. Thus, it is easy to hold with fingers both when moving and when it is fixed, and even when there are many pieces, it is not bulky and is considered to be strong (see, for example, Patent Document 1).
JP 2000-309327 A

  However, the conventional food container is a dish-shaped container for storing cakes and the like, and when applied to a deep container, the weight of the container body and its contents is applied to the knob part, and the strength including the fixing part of the knob Due to the shortage, it is difficult to stably hold the container body, and there is a risk of spilling the contents in the container.

  In addition, if it is made of thick melamine resin or earthenware, the molding process and member joining process for each member is laborious and the material cost and weight are increased, so that it can be obtained inexpensively, easily obtained, and lightweight I couldn't get it.

  Therefore, the present invention is for a lightweight food that can be easily obtained as an inexpensive product that is easy to stably hold the container body even if it is a deep container, is less likely to spill the contents in the container. It is an object to provide a container.

  The present invention takes the measures (1) to (3) in order to solve the above problems.

(1) That is, the food container of the present invention is composed of a container body 1 having an opening at the upper edge, and a heel part 2 projecting obliquely downward from at least a part of the upper edge of the container body 1. A food container in which a holding space 3 for inserting a user's hand is formed between the main body 1 and the heel part 2,
The container main body 1 and the flange portion 2 are each formed of a curved and / or bent plate-like body and integrally formed.

  When the container body 1 is held by placing the heel part 2 on the upper part of the hand and inserting the palm 2 into the holding space 3 of the food container so that the palm is in contact with the container body 1 with the thumb up, the container protrudes obliquely downward. The heel part 2 will be fitted to the back side of the hand from the upper part of the hand toward the outer side obliquely downward. At this time, since the angle formed between the container main body 1 and the heel part 2 is relatively small compared to, for example, the case where the horizontal heel part 2 is used, the weight of the container main body 1 and its contents fits on the back side of the hand. The palm is applied from the portion 2 toward the palm, and the palm is pressed against the container body 1. Thereby, the container main body 1 can be stably held without spilling food in the container.

  Further, since the single original plate O is integrally formed by vacuum forming, it is not necessary to go through a molding process or a member joining process for each member, and can be easily obtained as a relatively inexpensive one. it can.

  (2) In the food container, the heel portion 2 is connected to the upper edge of the container body 1 by a continuous edge 11 that is convexly curved outward in plan view, and protrudes upward from the continuous edge 11. It is preferable that it is comprised from the curved board. Further, it is preferable that the curved plate has an inclined curved surface having a convex surface on the upper side and the outside in plan view.

  In such a case, the flange portion 2 and the container body 1 are firmly connected by the curved continuous edge 11 and the curved surface of the flange portion 2 connected thereto, and the strength of the continuous portion is relatively high. It can be. In addition, the angle formed by the container body 1 and the heel part 2 is maintained within a predetermined connection angle over the entire connection edge 11, and the fit to the back side of the hand is good.

(3) In the food container, the container body 1 is formed by extending a circular region in the central portion of one substantially rectangular master plate O,
The flange 2 is formed by extending a three-side region surrounded by two sides of one corner of the original plate O and a part of the circular region of the central portion,
It is preferable that the intersection of two sides of the three side regions of the corner portion is a ridge portion 21 protruding from the container body 1.

  If it is such, the area of the original plate O can be used efficiently, and the continuous formation by the single large original plate O is attained. In particular, if the container main body 1 and the flange portion 2 are integrally formed by vacuum forming, a large amount of the integrally formed body of the container main body 1 and the flange portion 2 is continuously produced from one original plate by one vacuum forming step. Can be formed. This is excellent in the manufacturing efficiency of the integrally molded body of the container main body 1 and the flange 2.

  By taking the above means, it is easy to stably hold the container body 1 even in a deep container, there is little risk of spilling the contents in the container, and it can be easily obtained as an inexpensive one. A food container can be provided.

  The best mode of the present invention will be described below with reference to the drawings shown as examples. 1 to 9 show a food container of Example 1, and FIGS. 11 to 14 show a food container of Example 2, respectively.

Being done. A holding space 3 into which a user's hand is inserted is formed between the container main body 1 and the collar 2. And a user's hand can be inserted and hold | maintained in the holding space 3 between the curved concave surface of the said protrusion inner side surface, and the curved convex surface of an opposing part outer surface.

  The container main body 1 and the collar part 2 are integrally formed by vacuum forming the original plate O in one rectangular area.

  The eaves part 2 is connected to the upper edge of the container body 1 by a continuous edge 11 formed by convexly curving from the upper edge of the opening of the container body 1 to the outside in plan view. The flange 2 is formed of a curved plate that protrudes from the semicircular partial periphery of the connecting edge 11 and has a convex surface on the upper side and the outer side in plan view. The curved plate has a mountain-shaped cross section in which the center in the width direction is located at the top and both ends are located at the bottom. In addition, the flange portion 2 has one corner portion of the original plate O in the rectangular area as the top portion 21 that protrudes most from the container body 1.

  The overhanging inner surface of the flange part 2 facing the container body 1 has a curved concave surface curved with a first curvature in plan view, and of the outer surface of the container body 1 is opposed to the inner surface of the flange part 2. The outer surface of the main body has a curved convex surface curved with a second curvature larger than the first curvature in plan view. Specifically, the overhanging inner surface of the collar portion 2 located at the outer edge of the holding space 3 has a curved concave surface curved with the first curvature. Moreover, the main body outer side surface of the container main body 1 which opposes the inner side surface of the collar part 2 located in the holding | maintenance space 3 inner edge has a curved convex surface curved by the 2nd curvature larger than a 1st curvature.

  When holding the container body 1, as shown in FIG. 1, the user's hand is inserted into the holding space 3 between the outer side surface of the opposing portion and the inner side surface of the overhang so that the thumb is on top. . The container is held such that the palm side of the user's palm is applied to the outer surface of the facing portion and the heel portion 2 is placed on the back of the hand or the outer surface of the index finger.

  The food container of the present invention is basically integrally formed from a container main body 1 having an opening at the upper edge and a curved plate-like ridge 2 projecting obliquely downward from at least a part of the upper edge of the container main body 1. Being done. A holding space 3 into which a user's hand is inserted is formed between the container main body 1 and the collar 2. And a user's hand can be inserted and hold | maintained in the holding space 3 between the curved concave surface of the said protrusion inner side surface, and the curved convex surface of an opposing part outer surface. Hereinafter, each configuration of the embodiment will be described in detail.

  The food container of Example 1 is a so-called external fitting in which a lid staircase frame 41F provided at the lower edge of the lid body 4 is fitted outside the convex frame 11F provided at the upper edge of the container body 1. It is a combination type (FIGS. 1 to 10). The container body 1 is provided with a plurality of main body steps 12 so that the diameter of the container body 1 is gradually reduced from the upper side to the lower side. (See FIG. 1).

(Container body 1)
The container main body 1 accommodates food as an accommodation and is opened upward, and the food as the accommodation can be taken out from the upper opening. The shape of the container main body 1 may be any shape as long as it can be grasped by hand, but in order to stably hold it by hand, the main body tilt angle toward the inside of the container main body 1 with respect to the vertical direction. It is preferable to tilt downward with 1θ. In addition, the container body 1 of the embodiment has a vertical outer shape whose height is larger than the representative length in the width direction, has a deep housing shape, and the body inclination angle 1θ is in the range of 5 degrees to 30 degrees. (FIG. 3).

  The upper edge of the container body 1 is provided with a continuous edge 11 that continuously connects the flange 2. The continuous edge 11 includes a convex frame 11F protruding upward. Specifically, the convex frame 11F has an inverted U-shaped cross section that expands outward with a predetermined frame width 11W equal to the entire circumference of the container body 1 and is bent downward on the outer periphery (FIG. 2, FIG. 2). 3). As shown in FIG. 8, the lid step frame 41F of the lid body 4 is fitted to the convex frame 11F and closed. Further, a fitting groove 11D having the same height is provided on the outer peripheral surface of the continuous edge 11 as an annular concave groove along the periphery. When the lid is closed, the fitting rib 41L of the lid body 4 is fitted into the fitting groove 11D.

  The continuous edge 11 also has a narrow continuous edge return piece 112 bent in a substantially horizontal direction along the peripheral edge, thereby ensuring strength (FIG. 2).

  The main body step 12 of the first embodiment is provided at regular intervals in the height direction. Each of the main body step portions 12 is an annular main body step portion 12 having the same height along the side periphery of the container main body 1, and is provided so that the lower side of the main body step portion 12 is reduced in diameter (FIGS. 1 and 2). . The bottom is recessed into a small circle with the same center, and an annular grounding portion 13 is formed on the outer periphery thereof (FIG. 2).

(Human 2)
The eaves part 2 is connected to the upper edge of the container body 1 by a continuous edge 11 that is convexly curved outward in plan view, and is composed of a curved plate that protrudes from the continuous edge 11 and has an upward convex surface ( 1, 3, 5). By being formed by a curved plate integrally extending outward from the partially circular connecting edge 11, the weight including the contents can be reduced while being an inexpensive one made of a relatively thin plate-like body. In addition to having sufficient strength to support, fitting is performed so as to cover the outside from the upper part of the hand inserted into the accommodation space, thereby enabling stable holding of the contents (FIG. 1).

  Moreover, it has the 1 or several top part 21 (one top part 21 in an Example) projected from the container main body 1 (FIG. 5). The summit portion 21 is a crossing portion of two sides that intersect substantially vertically, and constitutes a corner portion of the position of the forming shape of the original plate O before vacuum forming. In the embodiment, the intersecting portion has a rounded round shape so that the hand hitting the hand is soft.

  Moreover, it has the narrow turning piece 22 folded back on the opposite side to the said bending direction along the outer periphery of the collar part 2 of the plate-shaped body curved upward and outward (FIGS. 3 and 5). While the strength of the peripheral part of the collar part 2 is raised by the turning piece 22, the curved shape is easily maintained. In addition, the plate-like body may be bent and formed with one or a plurality of ridgelines from a part of the continuous portion with the main body toward the crest portion 21 (not shown).

  The heel part 2 is also inclined downward and outward at a heel inclination angle 2θ with respect to the vertical direction. The heel inclination angle 2θ is set at any angle between 5 degrees and 80 degrees. The heel inclination angle 2θ is large enough to cover the outer side from the side of the index finger corresponding to the upper side of the gripped hand and easily hang on the hand, and to ensure the strength of the connecting portion with the container body 1 in advance. It is preferable. Specifically, it is particularly preferably between 55 degrees and 65 degrees. If it is smaller than this, the hand inserted into the holding space 3 cannot be pressed to form the sufficient holding space 3, and if it is larger than this, it is difficult to ensure the strength of the continuous structure. This is based on the fact that the position of the top portion 21 of the heel portion 2 is further away from the container body 1 in a plan view, and the moment due to the vertical force applied to the collar portion is increased.

(Retaining space 3)
The holding space 3 includes an outer peripheral side surface of the container main body 1 inclined at a predetermined main body inclination angle 1θ, a continuous edge 11 having a predetermined frame width 11 W formed on the upper edge of the container main body 1, and an outer side of the continuous edge 11. Is a space formed between the inner peripheral side surface of the flange portion 2 that is connected to the inner periphery of the flange portion 2 and is inclined at a predetermined flange inclination angle 2θ.

At the boundary between the fallen main body and the lid staircase frame 41F, a plurality of four lid frame connecting ribs 41C are provided for each phase such as a plan view. The lid frame connecting rib 41C is formed of a semi-cylindrical outward convex portion and is provided to ensure strength. A plurality of fitting ribs 41 </ b> L made of a concave recess recessed inward are formed on the outer peripheral surface of the lid staircase frame 41 </ b> F at the same height. The fitting rib 41L is fitted in the fitting groove 11D of the container body 1 so as to be closed substantially in a sealed manner.

  A narrow lid frame return piece 412 is formed on the lower peripheral edge of the lid body 4. The lid 4 is continuously formed with a lid knob portion 42 for pinching and opening. The lid knob portion 42 of the embodiment has a substantially isosceles triangle shape in plan view in which the hypotenuse is curved inwardly along the outer peripheral shape of the container body 1, and the tip has a rounded round shape.
