Description

Grape delivery box with buoyant, cold and buffer functions by application of super absorption polymer (SAP)}

The present invention relates to a box for courier service of grapes with buoyancy, cold storage, and cushioning functions by applying a super absorbent polymer (SAP), and more specifically, a space is formed inside the box to fit the shape of grapes, and a buffer material of grapes in the space It is about a box for delivery of grapes that uses SAP's characteristics of buoyancy, cold storage, and cushioning to fill SAP with furnace.

Grape is a deciduous vine of the grape family. In Korea, seeds such as ‘Campbell’, ‘Delaware’, and ‘Geobong’ are mainly grown in Korea. These grapes have a high content of glucose, which is good for relieving fatigue and rich in vitamins, which not only facilitates metabolism, but also has many polyphenols such as minerals and tannins, making it a fruit that is comparable to a single meal.

Globally, grapes account for about 30% of the total fruit production, but this is mostly for wine, and the proportion of grapes grown for reproduction is not very high. This is due to the characteristics of grapes, and decay and separation of grapes from grape clusters occur after a certain period of time after harvest or when impact is quickly caused by decay and retraction. , More production for processing. Prior to the Middle Ages, refrigeration and transportation techniques were not developed, so grapes for reproduction were treated as luxury, and most grapes were consumed as processed foods such as wine and raisins.

However, with the development of refrigeration and transportation in modern times, the opportunity to enjoy grapes for reproduction has increased significantly, and accordingly, the cultivation of grapes for reproduction has also increased significantly.

In the case of reproductive grapes, it is common to cultivate them with paper bags to prevent pests and pests. After harvesting, it is common to sell them in boxes with the paper bags intact. However, since a special buffer is not used in addition to the paper bag, the product value is easily damaged due to the occurrence of detachment and alteration due to impact.

In addition, in the case of reproductive grapes, long-distance transportation, especially when sending courier, causes a lot of detachment due to the impact, and even when packaging using a cushioning material, the impact between each grape cluster occurs, so it is difficult to completely prevent it. Therefore, there is a need for a packaging method capable of generating high added value by preventing the separation of grapes during long-distance transportation and courier delivery.

Hereinafter, preferred embodiments of the present invention will be described in detail. In the description of the present invention, when it is determined that a detailed description of related known technologies may obscure the subject matter of the present invention, the detailed description will be omitted. Throughout the specification, when a part “includes” a certain component, this means that other components may be further included instead of excluding the other component, unless specifically stated to the contrary.

The present invention can be applied to various transformations and can have various embodiments, and thus, specific embodiments will be illustrated and described in detail in the detailed description. However, this is not intended to limit the present invention to specific embodiments, and should be understood to include all conversions, equivalents, and substitutes included in the spirit and scope of the present invention.

The terms used in the present invention are only used to describe specific embodiments, and are not intended to limit the present invention. Singular expressions include plural expressions unless the context clearly indicates otherwise. In the present invention, terms such as include or have are intended to designate the existence of features, numbers, steps, operations, components, parts, or combinations thereof described in the specification, and one or more other features, numbers, or steps. It should be understood that it does not preclude the existence or addition possibility of the operation, components, parts or combinations thereof.

The present invention is provided with a plurality of indentation grooves that can hold grapes one by one in a courier box, wherein the indentation grooves are formed in an octagon with a length longer than the length of the horizontal to fit the shape of the grapes, within the indentation groove The upper and lower grapes are filled with SAP, and a super absorbent polymer (SAP) is applied to provide a buoyancy, cold storage, and cushioning function for a grape delivery box.

The concave groove 100 is a space in which grapes can be stored one by one, and is preferably formed in an octagon having a length longer than a length of the horizontal to fit the shape of the grapes. In general, the grapes have an upper portion of the cluster that grows larger than the lower portion. Therefore, the recess groove 100 is preferably formed in a shape in which the length of the upper horizontal is longer than that of the lower horizontal, and the length of the horizontal becomes shorter as it enters the inside. Do.

In addition, the recess groove 100 may have a horizontal length of 12 to 14 cm, a vertical length of 23 to 25 cm, and a depth of 12 to 14 cm. If the width is less than 10cm, the length is less than 23cm or the depth is less than 10cm, it is difficult to store grapes inside, and if the length is 15cm, the length is 25cm, and the depth is more than 15cm, it is packaged in the general standard. Out of the box (45 ~ 50cm width, 25 ~ 30cm height, 15 ~ 25cm height), the transportation cost and the box manufacturing cost may increase. In particular, when the length of the width exceeds 15 cm, the number of packages in one box is 2 or less, so the efficiency of packaging may be deteriorated.

A super absorbent polymer may be filled in the recess groove 100. The superabsorbent polymer is composed of sodium acrylate, which is a mixture of acrylic acid and sodium hydroxide, and can absorb water 100 to 130 times its own weight. In addition, the superabsorbent polymer that has sufficiently absorbed moisture has elasticity, and thus, it can be used for shock absorption, and because of its high specific heat, it can be used as a coolant.

The superabsorbent polymer is spherical with a diameter of 0.5 to 2 cm, and preferably contains 98 to 99.8% by weight of water. If the diameter is less than 0.5cm, the bunches of grapes are buried between them, and thus, the detachment due to impact may be severe, and if it exceeds 2cm, the impact prevention performance may be deteriorated because it is not uniformly filled. In addition, when the moisture content of the superabsorbent polymer is less than 98% by weight, elasticity falls and impact absorption power is reduced, and at the same time, cold storage performance may be deteriorated. If it exceeds 99.8% by weight, moisture may elute and productability may deteriorate.

The superabsorbent polymer may further include a preservative. The superabsorbent polymer is used after absorbing moisture and is used for shock absorption and cold storage of grapes with microorganisms on its surface. Therefore, when using a superabsorbent polymer that absorbs moisture, it may deteriorate or decay during transportation. Therefore, it is preferable to further contain a preservative in the superabsorbent polymer to prevent deterioration and decay. The preservatives used at this time may be stabilizers, fungicides, antifungal agents, antioxidants, or a combination of these to suit the purpose and usage.

The grape delivery box can be made of expanded polystyrene. In the case of the courier box, any material that can be molded into a shape that can accommodate grapes can be used without limitation, but it is preferable to use foam polystyrene for convenience and price in manufacturing and primary shock absorption during transportation.

A plurality of grooves 200 may be formed on the bottom surface of the recess groove 100 to prevent the flow of grape clusters or super absorbent polymers. The superabsorbent polymer or grape cluster may be loaded inside the recess groove 100. In this case, the superabsorbent polymer and the cluster of grapes are composed of spherical aggregates, which may move inside when transporting, thereby causing damage and detachment of grapes. Accordingly, it is preferable to install a plurality of grooves 200 to prevent flow on the bottom surface of the indentation groove 100 to prevent fluctuation of the superabsorbent polymer or grape cluster. At this time, the groove 200 may be formed directly on the bottom surface of the indentation groove 100, but after punching a sponge or foam polystyrene plate at a predetermined size and interval, then in close contact with the bottom surface of the indentation groove 100 It is also possible to use.

The grape delivery box includes a protrusion 300 corresponding to the indentation groove 100, and the protrusion 300 may include an upper finishing material that is inserted into the interior of the indentation groove by being inserted by 0.5 to 1 cm. . In the case of the grape courier box, the upper portion of the indentation groove 100 may be wrapped with a general plate material, but in this case, superabsorbent polymer or moisture may leak therein, and the preservation power of cold air is weakened, and the shelf life of grapes is weakened. This can be shortened. In order to prevent this, it includes a protrusion 300 corresponding to the indentation groove 100, and the protrusion 300 is inserted into the interior of the indentation groove 100 by coupling 0.5 to 1 cm into the upper finishing material to be coupled. It is desirable to wrap it in a closed package. At this time, if the protrusion is inserted to less than 0.5cm, the cold air preservation power and the ability to prevent the outflow of polymer or moisture may be weakened, and when it is inserted in excess of 1cm, the height inside the concave groove is low, making it difficult to pack grapes.

In addition, it is preferable that a plurality of grooves 210 are formed on the surface of the protrusion 300 to prevent the flow of grape clusters or superabsorbent polymers as in the interior of the grooves 100.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described to be easily carried out by those of ordinary skill in the art. In addition, in the description of the present invention, when it is determined that detailed descriptions of related well-known functions or known configurations may unnecessarily obscure the subject matter of the present invention, detailed descriptions thereof will be omitted. In addition, some features shown in the drawings are enlarged or reduced or simplified for ease of description, and the drawings and their components are not necessarily drawn to scale. However, those skilled in the art will readily understand these details.

Example 1

Using the expanded polystyrene, the same grape courier box as shown in FIGS. 5 to 8 was produced.

After mixing sodium hydroxide and acrylic acid, it was molded into a spherical shape of 1 mm, and immersed in water to prepare a super absorbent polymer having a diameter of 1.5 mm (moisture content 99.5 wt%).

After placing the 50 superabsorbent polymers on the bottom of the grape delivery box in the groove for the courier, put the plastic wrapped grapes (about 400g in weight), then add the 50 superabsorbent polymers to the top of the grapes (see Fig. 3). , Covered with the upper finishing material and sealed with tape.

Example 2

In Example 1, the diameter of the super absorbent polymer was prepared to be 0.5 cm, and then the same experiment was conducted.

Example 3

In Example 1, the diameter of the super absorbent polymer was prepared to 2 cm, and then the same experiment was conducted.

Example 4

In Example 1, the moisture content of the superabsorbent polymer was prepared at 95% by weight, and then the same experiment was conducted.

Example 5

In Example 1, the water content of the superabsorbent polymer was prepared at 99.9% by weight, and then the same experiment was conducted.

Example 6

In Example 1, instead of the super absorbent polymer, the same experiment was conducted using a sponge ball having a diameter of 1.5 cm used as a conventional buffer.

Example 7

It was packaged using a paper box in the same way as the existing packaging method, and grapes were inserted into the packaging material of the airbag method, and then the air was filled and sealed using a tape (see FIG. 4).

Experimental Example 1

The impact durability of the boxes for courier grapes prepared in Examples 1 to 7 was tested. In the laboratory at room temperature (temperature 25 ° C), a drop test of the courier boxes produced in Examples 1 to 7 was performed, and each drop was tested at a height of 100 cm using a drop tester (JYT-013-3, Jinyoung Tech, Korea). A total of six drops were conducted with the six sides in the falling direction. To obtain the average value of the experiment, the same experiment was repeated three times, and the number of detachment was determined by opening the box immediately after the experiment was completed.

As shown in Table 1, it was confirmed that in Examples 1 to 6 using the same packaging box as the present invention, the separation was significantly reduced compared to Example 7 using the conventional packaging method. In particular, in the case of Example 6, even though only the packaging box was replaced, it was confirmed that the number of detached particles decreased to 1/3 level. In addition, when comparing Example 1 and Example 6, it was possible to confirm the shock-absorbing performance of the super absorbent polymer, but in the case of Examples 2 and 4 having a small size or a low moisture content, the number of detachment was increased, so the shock absorbing power was increased. I could confirm that it was falling. In the case of Example 5, although it showed the most similar shock absorbing force as in Example 1, it was confirmed that the residual moisture remained in the indentation groove after the experiment.

Experimental Example 2

Cold storage preservation experiments were performed using the grape delivery boxes prepared in Examples 1 to 7 above. After installing a thermometer so that the measurement part of the thermometer was located on the side of the grape located inside the grape courier box, the grape courier box was stored at a temperature of 1 ° C. for 24 hours so that the temperature was 1 ° C. Thereafter, the grape courier box was left at room temperature (at an interval of 1 m each at 25 ° C.), and the change in temperature was recorded every 6 hours.

As shown in Table 2, in the case of Example 1 using the superabsorbent polymer of the present invention, it was confirmed that even after 48 hours, the preservation temperature of grapes (below 10 ° C) was maintained. In addition, in Examples 2 to 5, the temperature around the preservation temperature was maintained, and thus it was confirmed that the superabsorbent polymer had excellent cooling power. In the case of Example 6 without using the super absorbent polymer, it was confirmed that the cooling power was lowered and the temperature increased to 21 degrees after 48 hours. In particular, when compared to Example 1, the sponge absorbed moisture and dried the surface of grape It was confirmed that even the shape occurred. In the case of Example 7 using the existing packaging method, the storage temperature of grapes was greatly exceeded at the time when 24 hours elapsed, and the surface drying phenomenon was confirmed in the same manner as in Example 6.

Since the specific parts of the present invention have been described in detail above, it will be apparent to those of ordinary skill in the art that these specific techniques are only preferred embodiments, and the scope of the present invention is not limited thereby. will be. Accordingly, the substantial scope of the present invention will be defined by the appended claims and their equivalents.
