Fresh vegetable cold chain transportation fresh-keeping ice bag
Technical Field
The utility model belongs to the technical field of the cold chain equipment, specifically relate to a fresh-keeping ice bag of fresh vegetables cold chain transportation.
Background
Cold chain transportation means at the transportation overall process, all make the transportation that the goods of transporting remain the uniform temperature throughout, the transportation of very big part cold chain, put vegetables in the freshness preservation box, put into the ice bag in to the freshness preservation box again, it is fresh-keeping to cool down vegetables, then the loading is delivered to seller or consumer's hand, current ice bag only has the one deck usually, lead to the ice bag that is equipped with the cold-storage agent directly to expose outside, and then make and scrape the damaged probability greatly increased in the use, make the life of ice bag shorten. In addition, as the ice bag can seep out condensed water, the water quality of the refrigerated products is polluted, the quality guarantee of the low-temperature refrigerated transport products is not facilitated, and the refrigerated products are mildewed and damaged in severe cases.
Disclosure of Invention
The utility model provides a portable, cold-stored avoids the ice bag that is equipped with the cold-storage agent to expose outside, reduces the damage, increase of service life to through nimble mode of sealing, fresh vegetables cold chain transportation fresh-keeping ice bag that the cold-storage agent was added in the person's of facilitating the use later stage.
The utility model discloses a following scheme realizes: the utility model provides a fresh vegetable cold chain transportation fresh-keeping ice bag, is including the bag body 1 that has the inside cavity structure, setting water filling port and the outer protection bag 2 on bag body 1 upper portion, bag body 1 shape is oval column shape, is wrapping up the freezing medium, bag body 1 material is the nylon complex film, the outside at bag body 1 is established to outer protection bag 2 cover, keeps warm fresh it in the vegetables outside through laminating outer protection bag 2, and outer protection bag 2 is including the compound rete 3 of nylon, kraft paper layer 4 and the PE rete 5 that set gradually, the compound rete 3 of nylon adopts the compound inboard at kraft paper layer 4 of internal heat-seal layer 6, and PE rete 5 adopts adhesive layer 7 bonding complex in the kraft paper layer 4 outsides.
The gram weight of the kraft paper layer 4 is 100g per square meter; the outer surface of the kraft layer 4 is coated with an ink pattern.
Outer protection bag 2 is the rectangle of rectangle overlap joint upper end open-ended, and overlap joint 8 and bottom 9 all use hot melt technique once only to seal, and the upper end opening part is equipped with the strip of paper used for sealing 10 that is used for sealing the ice bag, and strip of paper used for sealing 10 constitutes the enclosed construction of mutual interlock by the arch and the sunken two-layer inboard around being located outer protection bag 2 respectively. When the ice bag is used, after the bag body 1 is filled with water, the water filling port is sealed, and then the two sides of the seal 10 are pressed tightly, so that a sealing structure can be formed, the sealing performance of the fresh-keeping ice bag is ensured, and the ice bag is prevented from water leakage.
Has the advantages that: (1) the utility model discloses bag body itself adopts the nylon complex film, and for the cylindroid, nylon complex film pliability is good, and the shaping that freezes is the cylindroid, and the use is difficult for broken hourglass, crisp rotten.
(2) The utility model discloses the bag external side is equipped with the outer protection bag of one end open-ended rectangle, and what can be convenient changes and/or supplements the cold medium in the bag body or the bag body. The contact area between the freshness protection package and the vegetables is larger than that of the traditional ice bottle, and the freshness protection effect is more durable. The outer protection bag is formed by compounding a nylon composite film layer, a kraft paper layer and a PE film layer, and meets the use requirements of the ice bag in the aspects of stiffness, strength and barrier property. And no condensed water is accumulated, so that the harm caused by the condensed water in the use process of the ice bag is better solved.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic view of the structure of the outer protection bag of the present invention.
In the figure: the bag comprises a bag body 1, an outer protection bag 2, a nylon composite film layer 3, a kraft paper layer 4, a PE film layer 5, an inner heat sealing layer 6, an adhesive layer 7, a lap joint 8, a bottom 9 and a seal 10.
Detailed Description
The present invention will be described in further detail with reference to examples.
Example 1: as shown in fig. 1-2, a fresh vegetable cold chain transportation fresh-keeping ice bag comprises a bag body 1 with an internal cavity structure, a water injection port and an outer protection bag 2, wherein the water injection port and the outer protection bag 2 are arranged on the upper portion of the bag body 1, the bag body 1 is made of a nylon composite film and is in an elliptic cylindrical shape, a freezing medium is wrapped by the nylon composite film, the outer protection bag 2 is sleeved outside the bag body 1, the outer protection bag 2 is subjected to heat preservation and fresh keeping by attaching the outer protection bag 2 to the outer side of a vegetable, the outer protection bag 2 comprises a nylon composite film layer 3, a kraft paper layer 4 and a PE film layer 5, the nylon composite film layer 3 is compounded on the inner side of the kraft paper layer 4 by adopting an internal heat sealing layer 6, and the PE film layer 5 is compounded on the outer side of the kraft paper layer 4 by adopting an adhesive layer 7.
Outer protection bag 2 is the rectangle of rectangle overlap joint upper end open-ended, and overlap joint 8 and bottom 9 all use hot melt technique once only to seal, and the upper end opening part is equipped with the strip of paper used for sealing 10 that is used for sealing the ice bag, and strip of paper used for sealing 10 constitutes the enclosed construction of mutual interlock by the arch and the sunken two-layer inboard around being located outer protection bag 2 respectively. When the ice bag fresh-keeping device is used, after the bag body 1 is filled with water, the water filling port is sealed, the bag body 1 is an oval icicle in winter, then the bag body is placed in the outer protection bag 2, two sides of the seal 10 are pressed tightly, a sealing structure can be formed, the sealing performance of the ice bag fresh-keeping device is guaranteed, and water leakage of the ice bag is prevented.
