Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a packaging container such as a pack-type food container.

[Prior Art] Pack-type food containers, which have been widely used in the past, consist of a container body integrally molded in various shapes such as square, triangular, trapezoidal, circular, and oval, and a container body integrally molded in the same shape as the container body. Generally, the container body is provided with a lid section, and both edges of the container body and the lid section are fitted and inserted into and removed from the container body. Also, food containers are often used that have several types of corner portions inside the container body so that various foods can be packed therein. Furthermore, containers in which the container body and the lid are integrally molded to facilitate opening and closing of the lid are also widely used.

[Problems to be solved by the invention] These pack-type food containers, which have been widely used in the past, all suffer from problems arising from the pack-type molding method, such as the weakness of the entire container body,
All of the food containers had disadvantages such as bendability, instability, breakage, etc., failure to open and close the lid, and inconvenience in handling.

Therefore, this invention was made in view of the above circumstances,
Even if the container body is integrally molded using lightweight and thin plastic material, the entire container must be molded to be strong and easy to handle, and opening and closing, which is the biggest problem when molding pack-type food containers, is important. The aim is to form the lid, especially to ensure that fitting and removal can be done with one touch, and to make the bottom of the container body and the edge of the lid stable and strong. To provide a packaging container that allows changing the shape of a lid part in order to pack a large amount of food.

[Means for Solving the Problems] The present invention was developed to solve the above-mentioned problems, and includes a hemispherical container lid 2 and an approximately triangular auxiliary lid located on one side. 3, a lid part 1 integrally formed with a lid rim 4 provided with a concave groove 5 into which the rim fits and a protruding piece 6 for attaching and detaching the rim, a circular container rim 8, and a lid rim 4 with a recessed groove 5 into which the rim fits and a protruding piece 6 for attaching and detaching the rim; Multiple folds 1
A container main body 7 formed by integrally molding a square container 9 having a trapezoidal slope 11 and a triangular slope 12 on the peripheral edge surfaces of a bottom surface 13 and an auxiliary container insertion/removal portion 16 located on one side; It consists of an auxiliary container 17 that is integrally molded into almost the same shape as the auxiliary container insertion/removal part 16 of the main body 7,
The auxiliary container molding part 15 located between the square container 9 and the auxiliary container insertion/removal part 16 is press-molded into a substantially semicircular shape, and a vertical side surface 14 is formed on the side surface of the square container 9. It is what it is.

[Function] According to the packaging container configured as described above, in order to remove the lid part 1 from the container body 7, first hold the container body 7 with one hand, and hold the lid edge of the lid part 1 with the other hand. By hooking the protruding piece 6 over the container 4 and holding it with your fingers, the protruding piece 6 can be removed from the container rim 8.
The lid part 1 can be removed from the container body 7. Then, the auxiliary container 17 is inserted from the auxiliary container insertion/removal portion 16 of the container body 7.
is taken out and food, etc. is put into it and the square container 9. At this time, the rectangular container 9 is given rigidity by the folds 10, the trapezoidal slope 11, and the triangular slope 12, so it is difficult to deform, and since the container lid 2 has a hemispherical shape, it can store a large amount of food, etc. The auxiliary container 17
It is difficult to bend due to the weight of food, etc. placed in it, and the container body 7 also does not tilt.

[Examples] Examples of the present invention will be described below with reference to the drawings.

1 and 4 show the packaging container of the present invention. Reference numeral 1 in the figure is a lid, which includes a hemispherical container lid 2 and an auxiliary lid 3 of an auxiliary container, which will be described later.
, a recessed groove 5 into which the edge surface is fitted, and a protruding piece 6 into which the edge surface is attached and detached, and are integrally molded. The reason why the container lid 2 is formed into a hemispherical shape is to make it possible to pack a large amount of food into the container body, which will be described later, and to make the lid rim 4 strong. It also has a design effect. In addition, the groove 5 formed in the lid edge 4 is
By arranging the caps at equal intervals as shown in FIGS. 1 to 3, the lid can be evenly brought into close contact with the entire edge of the container, so that the lid can be closed firmly and stably. In addition, since a protruding piece 6 is formed on the lid edge 4, fingers of the hand get caught on this protruding piece 6,
The lid part 1 can be opened and closed easily with one touch.

Next, regarding the container body 7, there is a square container 9 having a circular container edge 8, a plurality of folds 10 on the circumferential surface, and a trapezoidal slope 11 and a triangular slope 12 on the peripheral surface of the bottom surface 13. , an auxiliary container 1, which will be described later, is located on one side.
and an auxiliary container insertion/removal section 16 for inserting and removing the container 7, and are integrally molded. The reason why the container body 7 is made into a rectangular container 9 is to make the container easier to hold in the hand by making the sides of the container strong and by providing a corner portion and a flat portion. Also, the bottom 1
The reason why the trapezoidal slope 11 and the triangular slope 12 are formed in 3 is to strengthen the bottom part and to stabilize the bottom surface 13. In other words, the fold line 10 of the square container 9
By slanting the bottom surface 13 and forming the container body 7 into an equilateral triangular shape, the force applied to the container body 7 is distributed to the corner creases 10, further divided into two by the triangular slope 12, and then averaged to the bottom surface 13. This is because it is weighted. Further, the reason why the auxiliary container insertion/removal portion 16 is formed into a substantially triangular shape and compact is to stabilize the entire container body 1 and to facilitate the molding process. In particular, the auxiliary container forming section 15
The reason why the auxiliary container molding part 15 is made into an almost semicircular shape and is crimped is to strengthen the auxiliary container molding part 15, and also to prevent bending due to the weight of food, etc. when the auxiliary container 17 is inserted into the auxiliary container insertion/removal part 16. It's for a reason. Also,
The reason why the square container 9 side of the auxiliary container forming part 15 is made into the vertical side surface 14 is because when the auxiliary container 17 is inserted into the auxiliary container insertion/removal part 16, especially when heavy food is put in, the weight of the container body 7 is to prevent the auxiliary container 7 from tilting toward the auxiliary container insertion/removal section 16. Although the auxiliary container 17 is a container inserted into the auxiliary container insertion/removal section 16, it goes without saying that the auxiliary container insertion/removal section 16 can be directly used as the auxiliary container 17 without using this.

Next, a method of opening and closing the lid portion 1 will be explained with reference to FIG. First, hold the protruding piece 6 of the lid edge 4 with the thumb and fingers of one hand so that the hemispherical side of the lid part 1 fits into the palm of your hand. Next, hold the bottom surface 13 of the food container body 7 on one side. Place it on the palm of your hand and hold it between your thumb and fingers, align the lid rim 4 with the container rim 8, and push it inside. Then, as shown in FIG. 4, the container and lid edges 8 and 4 are fitted with one touch, and the lid 1 is hermetically sealed to the container body 7. At this time, the concave groove 5 of the lid edge 4 bites into the inside of the protruding piece 6 of the container edge 8, so that the lid part 1 is neither opened nor detached under normal conditions. Next, when opening and removing the lid part 1 from the container body 7, first hold the container body 7 containing food in one hand, then put one hand on the lid edge 4 of the lid part 1, and then If you pull and hold the protruding piece 6 with your other fingers, the protruding piece 6 will come off the container edge 8, so that the container body 7 and lid part 1 will be separated.
and can be opened easily.

[Effects of the invention] Since the present invention is constructed as described above, one hand holds the container body, the other hand hangs on the lid edge 4 of the lid part, and the protruding piece is pulled with the fingers. The lid can be removed from the container body by pinching and removing the protruding piece from the edge of the container. Then, the auxiliary container can be taken out from the auxiliary container insertion/removal section of the container, and food, etc. can be put into this and the square container. The container lid is hemispherical, so it is difficult to deform, and the container lid is hemispherical, so it can hold a large amount of food, etc. Furthermore, the semicircular auxiliary container molding part and the vertical side surface of the square container facing it make it difficult to deform. It is difficult to bend due to the weight of food, etc. placed in the container, and the container body does not tilt. Therefore, a highly rigid container can be obtained using a lightweight and thin plastic material, the container is easy to open and close, and there is no deformation of the auxiliary container insertion portion or inclination of the entire container due to the weight of the auxiliary container. Therefore, it is possible to provide a new type of pack-type packaging container that has not been seen before.
Especially when used as a container for food, the entire container is shaped to be durable and easy to hold, so it can be used not only as a packaging container but also as a tableware container, and it also has a smart appearance. Because it looks good, the food inside the container looks delicious, making it the perfect container to sell over-the-counter at department stores.
