Description

Fruit container {Fruit container}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a fruit container which is mainly used for selling fresh fruits such as strawberries per unit weight in a mountain area and sold to a consumer. The fruit container has a body and a lid in the same shape, A plurality of locking protrusions formed by the plurality of locking protrusions and the locking grooves are elastically coupled to each other to maintain the rigid sealing state, and even if the locking is carried out in a stacked state in multiple stages, the container is not crushed or the contents are not damaged. Even if vacuum molding is performed with a thin resin sheet So that it can retain strength.

Generally, fruits such as strawberries with thin skin and fleshy flesh are not picked or repacked in the middle distribution process because freshness and merchantability are lowered as they face each other. I sell it as a packaging container.

Meanwhile, it is common that strawberries use a small-sized circular basin as a packaging container. However, such a circular basin-shaped container has a troublesome problem of performing a separate taping operation at the time of packaging. The state of the inside of the container can not be visually confirmed, so that it can not increase the consumer's desire to buy. Also, since the internal moisture can not be discharged to the outside, the rust or other deterioration There is a concern that the air permeability is poor so that the merchandising property is unintentionally lowered during the transportation and storage process.

In addition, the above-described basin-type container has a problem that when the multi-layer lamination is carried out for sealing after tape-sealing, the taping state is erroneous, the lamination state is disturbed and, furthermore, There is a disadvantage in that the material cost for manufacturing a container used in a single use rises because the contents may be damaged due to collapse.

In order to solve such a problem, the 'upper and lower strawberry packaging container' of Patent Document 1 has a lower flange of the lower container and a fastening means for fastening the lower container and the upper container to the upper flange of the upper container, The upper container and the upper container can be easily installed and removed and the lower container and the upper container can be used interchangeably. However, since the strawberry packaging container of Patent Document 1 is manufactured by injection molding, the manufacturing cost is increased, And the material cost is also increased.

In addition, the 'agricultural product packaging container' of Patent Document 2 is a double joint member formed on the rim of the basin-shaped container, so that the lower container and the upper container can be bound to each other. However, There is a problem of an increase in cost and an increase in material cost.

On the other hand, in the containers disclosed in Patent Documents 3 and 4, the shape of the container body and the shape of the lid must be different from each other and must be stored and transported. Since the wrist joint was twisted to fit the angle of the body and the lid in order to align the direction of the lid, fatigue was easily accumulated and the joint formed in the container body and the lid was formed only locally, When the container is missed, the contents are opened and the contents are poured out.

Further, in addition to the above-mentioned patent documents, in case of a fruit container in which one side of the lid is integrally hinged to the container body, when the strawberry is put in the mountain, one side of the lid is lifted slightly, And there is also a disadvantage in that it is inconvenient to carry and store the container due to the instability of the container or the unbalance of the weight in the state that the lid is opened.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a method and a device for packaging and sealing the contents, Also, it is possible to quickly and easily maintain the air permeability without lowering the structural strength, and it is possible to prevent the contents from being poured even if the container is dropped because the opening phenomenon does not occur at the time of sealing. The present invention is to provide a fruit container which can be stacked, transported and stored so as to reduce a distribution cost.

In order to attain the above object, the present invention provides a vacuum molding machine, comprising: a polypropylene resin sheet having a predetermined thickness, which is inserted into a vacuum molding machine to form a recessed receiving portion having a bottom surface and a side surface for containing fruit therein; With a formed fruit container; A plurality of latching protrusions and latching grooves are radially formed alternately on the same radius, the latching protrusions are protruded toward the inside of the upper portion of the container, and the latching grooves are opened toward the lower outer side of the container, And the engagement protrusions and the engagement grooves are engaged with each other to receive the fruit therein.

Preferably, a plurality of reinforcing beads are formed concentrically on the bottom surface of the receiving portion to reinforce the structural strength, and a plurality of reinforcing beads are formed on the bottom surface of the receiving portion. A reinforcing bead is formed radially to cross the reinforcing bead on the floor.

According to the above-described embodiment of the present invention, since the plurality of latching projections and the latching grooves are radially engaged with each other as if they are sandwiched by the hand pods, they can be sealed in a very rigid state, Even if the container is stacked in multiple stages, the phenomenon that the lower container is pushed or spread by the weight of the upper part is not caused by the weight of the upper part, or the contents are squeezed, does not occur and the normal form can be stably maintained Since the container body and the lid can be arbitrarily combined without being influenced by the mutual direction or angle, it is possible to quickly and easily seal the container after the fruits are stored in the mountain area. The body and the lid Because it is made in a single form without a It is possible to stack and store in a stacked state, and thus the distribution and storage costs can be reduced.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 7, in the fruit container 100 according to the present embodiment, a polypropylene resin sheet having a predetermined thickness is inserted into a vacuum molding machine, and a floor (not shown) A circular rim portion 120 is formed on the outer side of the side surface 114 of the receiving portion 110 and the rim portion 120 ) Have a structure in which a plurality of locking projections 130 and locking grooves 140 are alternately formed radially on the same radius.

In this embodiment, the latching protrusion 130 formed on the rim portion 120 protrudes toward the inside of the upper portion of the container, and the latching groove 140 is opened toward the lower outer side of the container, The two fruit containers 100 and 100 'are brought into contact with each other at an arbitrary position so that the latching protrusions 130 and the latching grooves 140 are coupled to each other, It can be sold as a container.

The containers 100 and 100 'are made of the same size and shape, and the lower container 100' (main body) is formed of an opaque synthetic resin material and the upper container 100 (lid) It is preferable to make the content of the package stand out.

The containers 100 and 100 'according to the present embodiment (hereinafter simply referred to as "100" for convenience) are prepared by continuously feeding a polypropylene resin sheet having a predetermined thickness (0.3 to 0.7 mm) And it is made to have a sufficient thickness and a sufficient structural strength to be required for packaging and transportation of fruits. This is because the bottom surface 112 of the receiving portion 110 A plurality of reinforcing beads 113 are formed in a concentric shape so as to reinforce the structural strength and the reinforcement beads 113 of the bottom surface 112 are formed from the bottom surface 112 to the side surfaces 114 The reinforcing beads 115 are formed radially so as to intersect with the reinforcing beads 115.

In this embodiment, three reinforcing beads 113 formed on the bottom surface 112 are formed in a concentric circular shape. This is because a semicircular linear protrusion having a predetermined radius of curvature (1 to 3 mm) So that the flat bottom surface is prevented from being warped or twisted, and at the same time, even when the container is placed on a flat table, it is not slipped easily.

The reinforcing beads 115 radially formed on the bottom surface 112 and the side surface 114 may be formed in the shape of a semicircular linear protrusion such as the reinforcing bead 113 formed on the bottom surface 112, Like protrusions having a width of 1 mm are formed in combination so that the container itself can be effectively prevented from being crushed despite the load applied in the multi-stage stacking.

The radially reinforcing beads 115 in the form of strips are particularly designed to protrude outwardly from the other side of the boundary between the bottom surface 112 and the side surface 114 of the container, Can be effectively prevented.

The fruit containers according to the present embodiment were made from the polypropylene resin sheets having a thickness of 0.3 to 0.7 mm by the above-described reinforcing beads 113 and 115, and fruit containers each having a diameter of 25 to 30 cm and a height of 45 to 50 mm were prepared, And the resultant product was transported in 20 stages. As a result, it was confirmed that the original state of the container was maintained without damaging the contents or contents of the container at all.

4 to 6, the latching protrusions 130 are protruded toward the inside of the upper part, and the latching grooves 140 are opened toward the lower outer side, So as to maintain the sealed state.

The latching protrusions 130 and the latching grooves 140 are located outside and inside with reference to virtual circles having the same radius. The latching grooves 140 are formed on the upper side with the latching protrusions 130 And is formed to have a predetermined radius of curvature or a predetermined inclination angle so as to be smoothly introduced.

In the present embodiment, a semicircular ventilation groove 150 is formed on the left and right sides of the upper surface of the latching groove 140. The ventilation groove 150 is formed by inserting fruits (strawberries, etc.) And the moisture contained in the fruit can be discharged to the outside, so that water can not be discharged to the outside of the container, resulting in deterioration of fruit or deterioration of other taste or quality So that the occurrence of the phenomenon can be prevented.

The ventilation groove 150 serves not only as a ventilation function but also as a reinforcing bead for stably maintaining a predetermined angle formed by the rim portion 120 with the side surface 114 of the accommodating portion 110 And the upper and lower ventilation grooves 150 are brought to the same position in a state where the upper and lower containers 100 and 100 'are joined together to form a circular opening, ) Direction, and the air is discharged and the moisture is discharged.

In the fruit container of this embodiment having the above-described structure, since the engagement protrusion 130 and the engagement groove 140, which are alternately formed in the radial direction at the time of sealing, are combined as if they are sandwiched by hand pods, Since the opening of the container does not occur, it is possible to prevent an accident that the contents are poured. The latching protrusions 130 and the latching grooves 140 are protruded toward the inside of the top and open toward the bottom outside, As shown in FIG. 7, the phenomenon in which the locking protrusions tend to expand outward even when they are stacked and subjected to the upward and downward compressive forces causes the locking grooves to be pinched, and the locking grooves to become inwardly pinched by the locking protrusions, So that even if the container is stacked in multiple stages, the container is pushed or spread, or the contents are squeezed But this phenomenon does not occur, such as is possible to maintain a normal state in a stable manner.

The container according to the embodiment of the present invention grasps the thumb and forefinger of the left hand on the outside of the latching protrusion of the lower container when the container is opened and grasps the thumb and index finger of the right hand on the inside and outside of the latching projection of the upper side container If it is desired to open it more safely and more easily, insert the chopstick lightly into the ventilation groove 150 and press the lever upwardly or downwardly to push the lever downward. It is preferable to open it in the same manner when there is a fear that the contents are poured in the opening process.

In addition, since the container according to the embodiment of the present invention can be arbitrarily combined with the substantially same container body and lid regardless of directions or angles, it is possible to quickly and easily seal the container after the fruit is stored in the mountain area, Since the body and the lid, that is, the container itself, are formed in a single form, they can be stacked and stacked in multiple stages so as to have a minimum volume, so that the logistics costs and storage problems There is an advantage such that it can do.
