Description

Improved plastic box sealing structure

This creation is an improvement of the sealing structure of a plastic box, which provides a simple and safe pre-sealing of the bottom panel of the box.

With the development and use of packaging boxes, in response to the needs of different packaging uses, the development and use of various packaging boxes is extremely diverse and widespread. The most common traditional paper packaging boxes are easy to make, and environmental protection is easy to recycle. They are most commonly used by people. However, paper packaging boxes are usually made of corrugated cardboard. The most disturbing thing is that they are susceptible to moisture and become soft and deformed, resulting in damage, which affects the overall packaging safety. In addition, paper materials are made of wood pulp raw materials. Today, the cost is getting higher and higher, especially because of concerns about packaging safety. Therefore, the development of plastic packaging boxes came into being, especially with hollow honeycomb board plastic boxes, which are both lightweight, moisture-proof and safe. Characteristics, which is equivalent to the paper box structure. After the fixed box is unrolled for cutting, it is folded into a three-dimensional box structure. In the past, in order to reduce the volume of the stack, the box was usually folded first. Appearance, combined with stapling and storage. At the top and bottom of the box, only the bottom of the box is fixed with tape or nails when used for packaging, providing convenience Means use, to be filled after the completion of packaging, and then sealing the top of the box operation, and this The sealing operation of a segmented staple or tape sealing is actually inconvenient and troublesome for the recycling and classification after use, especially for the use of nails, because of the different materials, it also causes the trouble of environmentally friendly recycling. Similar sealing design requires the assistance of skilled technology and equipment to complete the packaging operation. Especially simple tape sealing or nail sealing, in fact, only has the closure between the bottom of the box. When large packing boxes or internal contents are heavy, plastic boxes are used. When the surface of the box is bonded with simple tape, it is often subject to internal pressure and it will pop up when it is moved, which will seriously affect it. To the safety of packaging, it will also cause dangerous situations of handling, and the adhesive tape will often contaminate the surface of the box body, which will cause troubles and inconveniences in handling during recycling or repackaging. Contact bonding is used, but it will cause the appearance of the contact at the contact point to be sag or melt unevenness, not only difficult to control the bonding quality, but also affect the appearance of the flat and beautiful; how to develop a plastic plate system The packing box has the characteristics of safe, light and practical filling, and its sealing structure is set to be environmentally friendly and easy to store and stack. When used in packaging, the box combination structure can be easily folded and sealed. The need for use contains space and practicality for further active R & D design.

In view of the use and production of the aforementioned traditional plastic packaging boxes, compared with the design and assembly of the bottom sealing box, the creator does not meet the practicality, convenience, safety, and the lack of practicality that causes environmental protection and recycling inconvenience. He improved the design and finally developed this creation. An improved sealing structure of a plastic box is provided. The left and right sides of the box bottom plate are provided with different cutting plate shapes that are symmetrical to each other, and the relative end positions of adjacent plates are overlapped, and relative perforations are provided for supply. It is locked with a plastic combination nail stack, and the beveled edges are cut symmetrically according to the two relatively short side plates, so that the sealed bottom surface can be fixed and stacked in an oblique direction, and the packaging and sealing operations are simplified simultaneously. , Does not meet the practical convenience and lack of impact on packaging safety.

The main purpose of this creation is: through the symmetrical cutting of the two opposite sides of the box bottom surface and the preset perforation of the stack of adjacent laminated plates, which are used to seal the box with plastic combination nails. When packaging, Only simple opening of the box can achieve the flat bottom of the box and automatically close the box. It is firmly fastened by plastic nails to provide the sealing strength of the box bottom and ensure the packaging load safety is greatly improved. The inner edge of the box top plate, The opposite male and female velcro tapes are preset on the opposite laminated board surface to provide simple and convenient sealing and gluing operations after the packing box is filled. When the box is recycled after use, simply push the bottom of the box back into the box, then The side of the box body is laminated into a plate shape for convenient storage, and the practical purposes of simple and safe packing of the packing box and safe use are achieved.

In order to facilitate your review members to further understand the characteristics of this creative structure and its practical purpose, I would like to explain in detail with the following examples: The view is roughly equivalent to the current box structure. The sealing structure of the entire plastic box is improved. Please match the first to sixth figures. The main improvement design is: the box bottom sealing structure design in advance, according to the appearance of the box body (10). Taking a general rectangular box as an example, the opposite long and short sides of each pair are provided with relatively different shapes of sealing long and short side plates (11, 12) for sealing lids, of which the long side plates ( 11) A concave V-shaped notch is set in the center. Usually, the bottom edge of the groove is just at the centerline of the bottom surface sealing. The two sides of the groove are divided into different sealing plate surfaces, and one side is provided with a sealing group. Several perforations (13) are used for stapling, and the other side surface is located at the position where the holes are overlapped with each other, and a reaming hole (14) with a larger ring diameter is provided, and the left side of the two opposite long side plates (11) of the box is left The right and left sides of the board are cut with different symmetrical holes. With the adjacent short side board (12) on both sides, according to the needs of the stack, the same symmetrical left and right chamfered edges are cut. And the short side plate (12) on the other side of the overlapping plate is provided with a perforation (131) corresponding to the perforation (13) on the long side plate (11). When the box is assembled, the box bottom of the stack is assembled. The surface is placed on the auxiliary device of the preset box sealing module, and the plastic combination nail (20) for box sealing is placed on the preset cavity of the module for protruding and directional insertion, so that the box sealing is nailed. Convenient operation without special technical dependence. An open slot (21) is provided in the center of the entire combination nail (20), so that the protruding top section of the rod is in the shape of a hollow hollow rod, and the convenient protruding top edge can be made slightly. For telescoping operation, its rod-shaped bottom has end pieces (22) with appropriate thickness on the large stern surface, and it also has the rigidity of locking and positioning after locking to ensure the safety and stability of the sealing and locking. The protruding end is shaped to form a large convex ring (23), and an inverted hook-shaped beveled surface is provided on the top edge of the outer end of the ring body to provide a fastening ring (24) for fastening. Simply push into the inner edge of the snap ring (23), and The convex ring (23) is spaced from the bottom end piece (22), and is slightly longer than the thickness of the two stacked plates, so that the nail can pass through the opening groove (21) to deform and easily extend to the top of the stacked plate. And the rod-shaped outer top is fixed and assembled by using a fixing ring (24); when the box bottom is sealed, the connected perforations (13, 131) of the stacked group are inserted above the combined nail (20), so that The nail can be pushed out above the stacked plates, and then fastened with the fixing ring (24), so that it can just abut the two plates of the stack group to form a nailed state, so as to reach the safe sealing of the bottom plate. Locking to provide safe use of object packaging. After the entire bottom plate stack is sealed, it is cut by symmetrical cuts with respect to the long and short side plates (11, 12), so that the bottom is spread out and flattened. The box body (10) can be easily sealed. When it is stowed, it is only necessary to push the bottom plate facing the inside of the box to store it, and the box body can be simply side-folded to one side for easy storage into a laminated cardboard It is convenient for the whole carton to be stacked to the minimum volume after the bottom of the box is sealed, as shown in the sixth figure.

When the package is taken out, the box only needs to be opened to form a body, and the bottom plate is opened to the outside to flatten, and the bottom of the box can be easily sealed and assembled to provide safety and convenience for the use of packaging. After the packaging operation, As shown in the fifth figure, the box sealing operation at the top of the box can be pre-positioned with male and female hook-and-loop fasteners (17, 16) at the relative positions of the adjacent long and short panels (15, 16) on the top surface. 18), providing users, after folding the two short panels (16) directly, after folding the long panel (15) into the seal, it can be automatically glued and assembled to achieve a simple closing operation and complete the sealing operation to make the plastic box It can be used in special packaging and box sealing to achieve simple and practical functions and purposes. It is especially convenient for recycling and storage and reuse of packaging boxes after use, which effectively reduces the overall packaging cost. To achieve the safety and convenience of packaging environmental protection and recycling and economic and practical purposes.

First, the plastic box has special moisture-proof and crash-resistant safe packaging practical characteristics, and is matched with the preset special tailored bottom surface folding. Assembly and assembly, with a simple through-nail fastening and assembly setting made of plastic combination nails (20) and fixing rings (24), which can make the bottom surface of each other's insert and combination achieve a solid and stable sealing structure, ensuring the structural packaging of the packaging box It is safe to use. The bottom of the combined box is complete without additional processing or sticking. It has a flat, beautiful and practical appearance, especially with the simple and solid design of the male and female hook-and-loop fasteners (17, 18) on the top to ensure packaging. The appearance of the box after sealing is complete, which is especially convenient for handling the stacking unit. The unpacked box is also recycled, because the bottom is nailed and assembled, and the symmetrical cutting characteristics between the plates on the opposite bottom surface can be easily removed. The bottom surface, after pushing from the outside to the top, can simply press the empty boxes laterally into a stack of plate-like storage, so that the box volume is shrunk to a minimum, which is convenient for storage and stacking, and provides repackaging Make At this time, when the box is only required to stand upright and the bottom is pushed out to a flat position, the sealing structure of the bottom of the box can be completed synchronously, which is convenient for repackaging and use. The small storage volume also has the practical effects of safe and convenient use, convenient for environmentally friendly recycling and safe packaging. The overall appearance of the box packaging is more beautiful and practical. It is indeed a new prefabricated sealing structure for similar plastic boxes. The new creation truly conforms to the safety and convenience characteristics of actual packaging use, and especially has the innovative and practical value of environmentally friendly recycling.

To sum up, the creative plastic box sealing structure of this creation is improved. It uses the symmetrical and chamfered and perforated stacks of the long and short sides of the box bottom surface to match the plastic combination. The nail piercing and sealing ensure the stability of the prefabricated sealing of the bottom plate of the box and maintain the safe use of the packaging box. Through the unique edge plate chamfering and sequential folding, the prefabricated box at the bottom of the box can be easily stacked. Reduce the storage volume of the boxes to facilitate the use of packaging and storage after folding. The entire sealing structure provides simple and easy operation of the box and safe practical use of packaging. In other words, it is indeed a brand-new structural design, more practical and effective, and has already met the requirements for a new patent application.
