By the way, when the container is tilted when picking up the product, the juice may leak or the contents may adhere to the lid, which impairs the value and appearance of the product. In this regard, in over-the-counter sales at supermarkets and the like, the consumer can lift the product with both hands, so the tilting of the container can be easily avoided.

On the other hand, in the food delivery service, the delivery person puts the product in a special backpack and delivers it. Insufficient space for loading and unloading goods. Moreover, in order to improve delivery efficiency, products may be packed without gaps. , it was easy to tilt the product.

SUMMARY OF THE INVENTION An object of the present invention is to provide a packaging container that allows a product to be lifted horizontally even with one hand.

In order to achieve the above object, the present invention provides a packaging container in which a lid formed by molding a synthetic resin sheet is fitted to a container body to close the lid, wherein the lid is provided on the outer periphery of the lid top plate. A fitting portion corresponding to the container body is formed, and a handle portion is provided at the center of the lid top plate so as to protrude upward. A handle top surface portion is formed on the upper end surface of the peripheral wall portion, and an annular finger hook portion is formed in the middle of the peripheral wall portion by narrowing the peripheral wall portion in the circumferential direction.

According to this means, the entire container in the closed state can be lifted by picking up the handle of the lid. Moreover, since the handle is formed in the center of the lid (top plate of the lid), the center of gravity of the lid is well-balanced, and the entire container in the closed state can be lifted horizontally without being greatly tilted.

Furthermore, since the finger rests are provided around the entire circumference of the handle, the handle can be grasped firmly. This finger-hooking part can be a ridge that protrudes outward from the peripheral wall part, so that the finger can be hooked on the narrowed part on the lower side. preferable. This is because slipping can be more reliably eliminated by inserting the fingertip into the concave groove.

Also, the concave groove (finger hook) can be formed perpendicular to the peripheral wall, but on the handle top surface side, it should be connected to the upper part of the peripheral wall by forming a reverse tapered surface that slopes inward. is preferred. Rather than making this part a horizontal plane perpendicular to the peripheral wall part, it is easier to insert the fingertip into the recessed groove, and the contact area with the fingertip is also enlarged to reliably prevent slippage when the handle is pinched. Because you can.

On the other hand, it is preferable that the lid top plate side of the finger hook portion (concave groove) is continuous with the lower part of the peripheral wall portion via a right-angled corner portion. With this means, a step is formed by the corner between the lower part of the peripheral wall and the groove. This is because the fitting force with the main body is maintained, and the closed state of the entire container can be maintained.

Furthermore, by making the top surface of the handle part concave toward the center in a mortar shape, the strength of the handle part is increased, deformation thereof is prevented, and stable picking up becomes possible.

Furthermore, deformation of the lid can be more reliably suppressed by providing concentric or radial reinforcing ribs around the handle on the lid top plate of the lid.

The container main body has legs that can be installed on the lid top plate of the lid on the bottom side, and the bottom surface inside the legs is raised to a height equal to or higher than the handle, so that the lid is closed. can be stacked.

According to the present invention, since the handle is formed in the center of the lid, by picking up the handle, the entire container with the lid closed can be lifted stably and horizontally, and can be used as a backpack for food delivery services. It is possible to greatly reduce the chances of contents adhering to the lid or leaking juice when goods are put in and taken out of a relatively narrow bag, bag, or box. Also, by picking up the handle portion, the edges of the lid and the container body are not touched by fingers or the like at all, so there is no inconvenience that the fitting portion between the lid and the container body is unintentionally released.

Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. 1 to 6 show a packaging container according to one embodiment of the present invention, which consists of a lid 1 and a container body 2. As shown in FIG. The lid 1 is formed by molding a thermoplastic non-foamed resin sheet, while the container body 2 is formed by molding a foamed resin sheet. As a result, the heat insulation and heat retention of the container body 2 are enhanced, so that in the food delivery service, the cooked product can be delivered in a so-called hot state without being extremely cooled. However, the container body 2 may be molded from a non-foamed resin sheet like the lid body 1 . On the other hand, if the lid body 1 is molded from a foamed resin sheet like the container body 2, heat insulation and heat retention can be further enhanced.

As details of each element, first, the lid body 1 has a lid top plate 1a as a main body and a handle portion 1b formed in the center. A ridge portion 1e having a trapezoidal cross section and having a higher height than the ribs 1c and 1d is formed concentrically. The reinforcing ribs 1c and 1d are intended to increase the rigidity of the lid top plate 1a, and in this embodiment they are formed concentrically. Alternatively, they may be formed radially from the handle portion 1b. Like the reinforcing ribs, the ribs 1e increase the rigidity of the lid top plate 1a and support the legs of the container body 2 from the inside during stacking, which will be described later.

As a lid closing means, a fitting portion 1f having a downward concave shape is continuously formed from the protrusion 1e to form an inner fitting that fits into the opening 2a of the container body 2. As shown in FIG. Therefore, in this container, the sealing performance when the lid is closed is higher than that of the outer fitting structure.

A horizontal flange 1g is formed at the peripheral end of the fitting portion 1f so as to overlap the opening flange 2b of the container body 2. As shown in FIG. Furthermore, a knob portion 1h and a receiving piece 2c projecting outward in the horizontal direction are formed correspondingly to a portion of the horizontal flange 1g and the opening flange 2b as lid opening means. Therefore, the lid can be easily opened by pulling apart the knob 1h and the receiving piece 2c of the container in the closed state.

In the packaging container having the structure described above, the most important feature of the present invention is the presence of a handle portion 1b formed on the lid top plate 1a of the lid body 1. As shown in FIG. The gist of this is that it is located in the center of the lid top plate 1a, projects upward from the lid top plate 1a, and has a finger hook. That is, as shown in detail in FIG. 4, the handle portion 1b has a peripheral wall portion 3 rising from the lid top plate 1a. A finger hook portion 5 is formed. Of these, the handle top surface portion 4 is a portion that maintains the closing property of the lid body 1 in a state in which the lid top plate 1a is raised directly upward by the peripheral wall portion 3 . Further, the finger hook portion 5 is a portion that literally catches a fingertip when picking up the handle portion 1b.

More specifically, the finger hook 5 is an inwardly recessed groove in this embodiment. In this regard, although it is possible to form the finger hooking portion 5 as a ridge that bulges outward, a recessed groove allows the fingertip to enter and provides a good grip.

Further, in this embodiment, the top surface portion 4 side of the finger hook portion 5 (concave groove) is formed to form an inversely tapered surface 5a that continues from the upper stage 3a of the peripheral wall portion 3 and inclines inward. As a result, when picking up the grip portion 1b, it becomes easier to insert a fingertip into the finger hook portion 5 (concave groove). In addition, when the depth of the concave groove is the same, the contact area of the fingertip is larger than when this portion is horizontal, and slipping when picking up the handle portion 1b is suppressed. However, in the present invention, forming this portion on a horizontal surface is not excluded.

On the other hand, the lid top plate 1a side of the finger hooking portion 5 (concave groove) is formed so as to be continuous with the lower stage 3b of the peripheral wall portion 3 via a right-angled corner portion 5c from the horizontal surface 5b. The corner portion 5c suppresses deformation such as upward elongation or twisting of the peripheral wall portion 3 when the grip portion 1b is picked up, thereby enabling stable picking up. However, in the present invention, forming this portion with an inclined surface is not excluded.

According to the packaging container having this configuration, as shown in FIG. 5, in the container closed by fitting the lid body 1 to the container body 2 containing the contents, the handle portion 1b is picked up. Thus, the entire closed container can be lifted horizontally. Therefore, when taking out a product straight up from a relatively narrow bag or box, such as a special bag for a food delivery service, the container can be lifted with one hand without tilting, preventing juice from leaking or contents on the lid. Avoid sticking.

In the present invention, the fitting force between the lid body 1 and the container body 2 is preferably as strong as possible in order to prevent the lid from being carelessly opened. In this case, it is a matter of course that the fitting portions are fixed in advance by cellophane tape, a stapler, or the like. In the present invention, it is sufficient for the fitting part to seal the inside of the container.

FIG. 6 shows a state in which the packaging containers having the above configuration are stacked. It forms a leg 2d to be installed on 1a. The leg portion 2d raises the inner bottom surface 2e to a height higher than the handle portion 1b. Therefore, the handle portion 1b can be stacked without interfering with the container body 2 on the upper stage. Horizontal displacement can also be restricted.

In addition, the present invention is not limited to the above embodiments, and the shape of the knob portion of the lid body may be changed (see FIG. 7(a)), or the plan view shape of the lid body (fitting portion) may be elliptical (see FIG. 7). (b)), a quadrangle such as a square (see FIG. 7(c)), or a polygon such as a hexagon (see FIG. 7(d)). 1 to 7, the shape of the handle when viewed from above is similar to that of the fitting portion, but as shown in FIG. It is also possible to make the plan view shapes of the fitting portion and the grip portion inconsistent, for example, by forming them. What is necessary in the present invention is to provide a handle in the center of the top plate of the lid, so that when the handle is picked up, the entire container with the lid closed is lifted horizontally, preventing the contents from leaking or becoming uneven. to avoid.
