Description

Technical Field

[0001] The present application relates to the field of packaging boxes, and particularly to a tissue box and its usage method. Background Art

[0002] In daily life, tissues are widely used as consumables, and the accompanying tissue boxes have become common household items. With the improvement of people's living standards and the transformation of consumption concepts, the demand for tissue boxes is no longer limited to their basic storage function, but also pays more attention to aspects such as environmental protection, cost control, and usage convenience. At the same time, the continuous enrichment and diversification of tissue products on the market also prompt the design of tissue boxes to be continuously updated to adapt to the packaging and usage requirements of different types of tissues.

[0003] Existing detachable tissue packaging boxes mainly adopt a disposable design. Under this design mode, when the tissues in the packaging box are used up, the entire packaging box will be discarded. This is the currently common processing method for tissue packaging and usage in this field, and many manufacturers follow such production and usage logic. This method enables consumers to use tissues without having to consider the reuse of the packaging box, and the usage is relatively direct and simple.

[0004] However, the disposable design of existing detachable tissue packaging boxes has obvious defects. Because relatively expensive magnets are often used in such packaging boxes, and when the packaging box is discarded after the tissues are used up, these magnets are also discarded, which not only causes waste of resources but also increases the long-term cost of consumers using tissues. Summary of the Invention

[0005] In order to facilitate the recycling of the main structure of the packaging box and effectively block the tissues when not in use, the present application provides a tissue box and its usage method.

[0006] The tissue box and its usage method provided by the present application adopt the following technical solutions: A tissue box and its usage method, including an inner box and an outer box. The inner box is used to hold tissues. A first easy-tear seal strip is provided on the upper surface of the inner box, and a second easy-tear seal strip is provided on the upper surface of the outer box. When through openings are provided on both sides of the outer box for the inner box to pass through, when the inner box is inserted into the inner part of the outer box, the first easy-tear seal strip and the second easy-tear seal strip are opposite to each other. When in use, by completely tearing the first easy-tear seal strip and the second easy-tear seal strip, the tissues in the inner box can be drawn out; the outer box is provided with a flip cover plate for blocking the opening torn at the second easy-tear seal strip; a magnetic locking structure is provided between the outer box and the flip cover plate for detachably connecting the movable end of the flip cover plate to the outer box; clamping structures are provided at both sides of the inner box, and the clamping structures are respectively used for clamping with both sides of the outer box.

[0007] By adopting the above technical solution, the inner box is used to contain paper towels, which serves as the main packaging structure of paper towels. The first easy-tear sealing tape and the second easy-tear sealing tape are torn off to extract paper towels; the opening of the outer box facilitates the smooth insertion of the inner box. The first and second easy-tear sealing tapes are aligned to ensure smooth paper extraction; the flap can cover the opening to prevent dust from entering and protect the paper towels. The magnetic locking structure allows the flap to be detachably connected to the outer box for easy opening and closing. The clamping structure clamps the inner box and the outer box on both sides, so that the inner box is stably fixed in the outer box, reducing the probability of the inner box detaching from the outer box in daily use. After the paper towels are used up, a new paper towel inner box can be replaced, while the outer box with the magnetic locking structure is retained, which is convenient for the outer box to be recycled, avoiding resource waste and reducing costs.

[0008] Preferably, the fixing structure is a third easy-tear sealing tape extending along the length direction of the inner box, a portion of the third easy-tear sealing tape located on the upper surface of the inner box is formed by a pre-cut weakening line, a portion of the third easy-tear sealing tape located on the side surface of the outer box is integrally connected to the side surface of the inner box, and when the third easy-tear sealing tape is torn off, one end of the third easy-tear sealing tape remains connected to the side surface of the inner box; limiting tapes are provided on both sides of the outer box, and a gap is formed between the limiting tape and the outer box for the third easy-tear sealing tape to be inserted and fixed.

[0009] By adopting the above technical solution, the inner box can be fixed inside the outer box by tearing off the third easy-tear sealing tape and inserting one end of it into the gap between the limiting tape and the outer box, which is convenient for installation; after using the paper towels in the inner box, the third easy-tear sealing tape can be pulled out from the gap to replace the new inner box, so that the outer box can be recycled, and the magnet in the magnetic locking structure on the outer box can also be recycled, which is conducive to reducing costs; the upper surface of the third easy-tear sealing tape is formed with a pre-cut weakening line to facilitate the tearing operation.

[0010] Preferably, the outer box comprises a connecting plate, a top plate, a front plate, a bottom plate and a rear plate which are connected in sequence, the flip cover plate is integrally connected to the bottom plate, and an adhesive layer is provided between the outer side of the connecting plate and the inner side of the rear end plate.

[0011] By adopting the above technical solution, the various structures of the outer box and the flip cover plate are connected as one piece. During distribution, the outer box can be disassembled into an integrated plate and folded for storage to avoid crushing and deformation. When in use, the connecting plate and the rear end plate are connected using an adhesive layer to facilitate on-site assembly of the outer box.

[0012] Preferably, the limiting belt extends along the width direction of the outer box, and both ends of the limiting belt are respectively adhered to the inner side of the top layer board, and the extending direction of the third easy-tear sealing belt is perpendicular to the extending direction of the limiting belt.

[0013] By adopting the above technical solution, the limiting belt extends along the width direction of the outer box and its two ends are adhered to the inner side of the top layer board. Cooperating with the third tear strip whose extending direction is perpendicular to that of the limiting belt, the third tear strip can smoothly pass through the gap between the limiting belt and the outer box and be clamped, ensuring that the inner box is stably clamped inside the outer box, guaranteeing the stability of the paper tissue box structure, facilitating subsequent paper tissue extraction and inner box replacement operations; it also facilitates the detachable connection between the inner box and the outer box, so that the inner box can be conveniently replaced after the paper tissues are used up, enabling the outer box to be recycled, reducing resource waste and lowering the usage cost.

[0014] Preferably, notches are provided on both sides of the top layer board, and part of the limiting belt is exposed at the notches, so that the third tear strip can penetrate into the gap between the limiting belt and the top layer board.

[0015] By adopting the above technical solution, notches are provided on both sides of the top layer board to expose part of the limiting belt, facilitating the penetration of the third tear strip into the gap between the limiting belt and the top layer board. Furthermore, it is conducive to the inner box being clamped inside the outer box through the third tear strip. Combining features such as the inner box accommodating paper tissues, the inner and outer boxes being provided with tear strips for convenient paper tissue extraction, the outer box being provided with a flip cover plate and a magnetic adsorption locking structure to block the paper tissue extraction opening, and the inner box being provided with clamping structures on both sides to be clamped with the outer box, etc., the functions of paper tissue extraction and protection are jointly realized, and it is convenient to replace the inner box, enabling the outer box to be recycled and reducing the cost.

[0016] Preferably, the magnetic adsorption locking structure includes a fixed magnet embedded at the top layer board of the outer box and a movable magnet embedded in the flip cover plate. When the flip cover plate covers the surface of the top layer board of the outer box, the movable magnet coincides with the fixed magnet in position and is magnetically adsorbed and locked.

[0017] By adopting the above technical solution, the magnetic adsorption locking structure adopts a fixed magnet embedded at the top layer board of the outer box and a movable magnet embedded in the flip cover plate. When the flip cover plate covers the top layer board of the outer box, the movable magnet coincides with the fixed magnet and is magnetically adsorbed and locked, which can realize the detachable connection between the movable end of the flip cover plate and the outer box, facilitating the opening and closing of the flip cover plate to access or block the paper tissues, ensuring the stability when the flip cover plate is closed, and at the same time, the outer box can be recycled, which is conducive to reducing the cost.

[0018] Preferably, the area of the second tear strip is larger than that of the first tear strip. When the inner box is inserted into the outer box, the first tear strip falls within the coverage range of the second tear strip.

[0019] By adopting the above technical solution, it can be ensured that when the second tear strip is torn, the first tear strip will surely be exposed, facilitating the subsequent tearing of the first tear strip to extract the paper tissues in the inner box and guaranteeing the smooth progress of the paper tissue extraction process.

[0020] A method for using a paper tissue box includes the following steps: S1. Tear open the third tear strip on both sides of the outer box, and then insert the inner box into the inside of the outer box through the opening of the outer box; S2. Pass one end of the third tear strip through the gap between the adjacent limiting strip and the outer box. The third tear strips on both sides of the outer box form a limiting structure to fix the inner box inside the outer box; S3. Tear open the second tear strip and the first tear strip completely in sequence, and draw out the paper towels in the inner box, so that the paper towels pass through the opening torn by the first tear strip and the opening torn by the second tear strip in sequence for the paper towels to be drawn out and used. When the paper towels are not in use, cover the upper surface of the outer box with the flip cover plate to block the paper towels. The outer box and the flip cover plate are locked through a magnetic locking structure; S4. When the paper towels in the inner box are used up, draw out the third tear strips on both sides of the outer box from the gap between the outer box and the limiting strip, then replace it with a new inner box, and repeat steps S1 and S2 to complete the replacement operation of the paper towel box.

[0021] By adopting the above technical solution, tearing open the third tear strips on both sides of the outer box facilitates the insertion of the inner box into the outer box. The third tear strips passing through the gap between the limiting strip and the outer box form a limiting structure to firmly fix the inner box inside the outer box; tearing open the first and second tear strips facilitates the extraction of the paper towels in the inner box. The flip cover plate combined with the magnetic locking structure can block and protect the paper towels when the paper towels are not in use; after the paper towels in the inner box are used up, drawing out the third tear strips can replace the new inner box, realizing the recycling of the outer box, avoiding waste of resources, and reducing costs.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the setting of the inner box and the outer box, only the inner box needs to be replaced after the paper towels are used up, and the outer box can be recycled, reducing costs; 2. A magnetic locking structure is arranged between the outer box and the flip cover plate, which is convenient for opening and closing the flip cover plate, convenient for extracting paper towels, and can block the paper towels to play a protective role at the same time; 3. A clamping structure is arranged on both sides of the inner box to be clamped with both sides of the outer box, so that the inner box is firmly inside the outer box, ensuring the stable position of the inner box during use.

[0029] The following further elaborates on the present application in conjunction with the attached Figures 1-5 drawings.

[0030] An embodiment of the present application discloses a tissue box. Referring to Figure 1 and Figure 2 , it includes an inner box 5 and an outer box 1. Among them, the inner box 5 is used to hold tissues, and the outer box 1 wraps the outer part of the inner box 5. The two cooperate with each other to achieve the purpose of making the inner box 5 replaceable and the outer box 1 recyclable, greatly reducing the use cost and avoiding waste of resources.

[0031] Referring to Figure 2 and Figure 3 , specifically, the inner box 5 includes a main structure for holding tissues and a first tearable seal tape 52 provided on the upper surface. The main body of the inner box 5 is generally made of paper material, having certain toughness and strength, and can well wrap and protect the tissues. The first tearable seal tape 52 is arranged on the upper surface of the inner box 5 in the way of pre-cut weakening lines, which is convenient for users to tear. Of course, other designs convenient for tearing can also be adopted, such as setting a pull ring on the seal tape. When tissues are needed, just gently tear the first tearable seal tape 52 to expose the tissues in the inner box 5.

[0032] Referring to Figure 4 and Figure 5 , the main body of the outer box 1 is also made of paper material, specifically including a connecting plate 11, a top layer plate 15, a front end plate 14, a bottom layer plate 13 and a rear end plate 12 connected in sequence. Among them, the flipping cover plate 2 is integrally connected with the bottom layer plate 13, and the flipping cover plate 2 can be flipped relative to the upper end of the bottom layer plate 13 to cover from the rear of the outer box 1 to the surface of the top layer plate 15 of the outer box 1. A bonding layer is arranged between the outer side of the connecting plate 11 and the inner side of the rear end plate 12. The bonding layer can adopt a tearable glue. After the outer side of the connecting plate 11 and the inner side of the rear end plate 12 are bonded, through openings are formed on both sides of the outer box 1 for the inner box 5 to be inserted.

[0033] Among them, the top plate 15 is located at the upper surface of the outer box 1, and a second tear tape 16 is provided at the top plate 15. The second tear tape 16 is also provided on the upper surface of the outer box 1 in the form of a pre-cut weakened line, and its area is larger than that of the first tear tape 52. When the inner box 5 is inserted into the inner part of the outer box 1, the first tear tape 52 just falls within the coverage range of the second tear tape 16, so as to ensure that after the second tear tape 16 and the first tear tape 52 are torn, it is convenient for the paper towels to be smoothly drawn out. The through openings on both sides of the outer box 1 are channels for the inner box 5 to pass through, and their sizes and shapes are adapted to the inner box 5 to ensure that the inner box 5 can be smoothly inserted into the inner part of the outer box 1.

[0034] The function of the flip cover plate 2 is to block the opening torn from the second tear tape 16, and when the paper towels are not in use, it can prevent dust and other sundries from entering the paper towel box. In this embodiment, a magnetic locking structure is provided between the flip cover plate 2 and the outer box 1. Specifically, the magnetic locking structure includes a fixed magnet 4 embedded at the top plate 15 of the outer box 1 and a movable magnet 3 embedded in the flip cover plate 2. The fixed magnet 4 and the movable magnet 3 can be made of strong magnetic materials such as neodymium iron boron to ensure sufficient adsorption force. When the flip cover plate 2 covers the surface of the top plate 15 of the outer box 1, the movable magnet 3 coincides with the position of the fixed magnet 4 and is magnetically locked to each other, so that the flip cover plate 2 can be stably fixed on the outer box 1.

[0035] In addition, clamping structures are provided at both side positions of the inner box 5. The clamping structures are specifically third tear tapes 51 extending along the length direction of the inner box 5. In this embodiment, there are a total of four third tear tapes 51, which are respectively arranged at the four corner positions on the upper surface of the inner box 5. The part of the third tear tape 51 on the upper surface of the inner box 5 is formed by a pre-cut weakened line for easy tearing, and the part on the side surface of the outer box 1 is integrally connected to the side surface of the inner box 5, so that when the third tear tape 51 is torn, one end of the third tear tape 51 remains connected to the side surface of the inner box 5.

[0036] Limit strips 17 are provided on both sides of the outer box 1. The limit strips 17 extend along the width direction of the outer box 1, and both ends of the limit strips 17 are respectively adhered to the inner side positions of the top plate 15. A gap is formed between the limit strips 17 and the outer box 1 for the third tear tape 51 to be inserted and clamped. In addition, notches 18 are provided on both sides of the top plate 15, and part of the limit strips 17 are exposed at the notches 18, so that it is convenient for the third tear tape 51 to penetrate into the gap between the limit strips 17 and the top plate 15, thereby firmly clamping the inner box 5 inside the outer box 1.

[0037] These components are combined together. First, prepare the outer box 1, tear open the third tear tape 51 on both sides, insert the inner box 5 into the interior of the outer box 1 through the through openings on both sides of the outer box 1, and then pass one end of the third tear tape 51 through the gap between the adjacent limiting tape 17 and the outer box 1, so that the inner box 5 is firmly clamped in the outer box 1. When in use, tear open the second tear tape 16 and the first tear tape 52 in sequence, and then the tissue paper in the inner box 5 can be taken out. When not in use, cover the flip cover plate 2 and lock it through the magnetic locking structure. When the tissue paper in the inner box 5 is used up, take out the third tear tape 51, replace it with a new inner box 5, and then it can be used continuously. Through such a combination logic, the inner box 5 can be replaced, and the outer box 1 can be recycled, reducing the use cost and resource waste.

[0038] Specifically, the method for using the tissue box provided by the embodiment of the present application includes the following steps: S1, Tear open the third tear tape 51 on both sides of the outer box 1, and then insert the inner box 5 into the interior of the outer box 1 through the through opening of the outer box 1. During the operation, use your finger to slowly tear along the pre-cut weakening line of the third tear tape 51 with moderate force to avoid tearing the tape. Align the inner box 5 with the through opening of the outer box 1 and insert it smoothly to ensure that the inner box 5 completely enters the interior of the outer box 1.

[0039] S2, Pass one end of the third tear tape 51 through the gap between the adjacent limiting tape 17 and the outer box 1. The third tear tapes 51 on both sides of the outer box 1 form a limiting structure to clamp the inner box 5 inside the outer box 1.

[0040] S3, Tear open the second tear tape 16 and the first tear tape 52 completely in sequence, and take out the tissue paper in the inner box 5, so that the tissue paper passes through the opening torn by the first tear tape 52 and the opening torn by the second tear tape 16 in sequence for the tissue paper to be taken out and used. When the tissue paper is not used, cover the flip cover plate 2 on the upper surface of the outer box 1 to block the tissue paper. The outer box 1 and the flip cover plate 2 are locked through the magnetic locking structure. When not in use, gently flip the flip cover plate 2 to cover the upper surface of the outer box 1. At this time, the movable magnet 3 in the flip cover plate 2 coincides with the fixed magnet 4 at the top layer plate 15 of the outer box 1 and magnetically attracts each other to achieve locking.

[0041] S4, When the tissue paper in the inner box 5 is used up, take out the third tear tapes 51 on both sides of the outer box 1 from the gap between the outer box 1 and the limiting tape 17 in sequence, then replace it with a new inner box 5, and repeat steps S1 and S2 to complete the replacement operation of the tissue box. Slowly take out the third tear tape 51 from the gap, take out the inner box 5 with the used-up tissue paper, put in a new inner box 5, and clamp the new inner box 5 inside the outer box 1 again according to the previous steps.

[0042] The implementation principle of this embodiment is as follows: the tissue box has a unique design of inner box 5 and outer box 1, as well as a clamping structure and a magnetic locking structure, so that the inner box 5 can be easily replaced and the outer box 1 can be recycled many times. The inner box 5 contains tissues, and the outer box 1 provides protection and fixation. The two cooperate with each other, which not only ensures the normal extraction of tissues, but also avoids the waste of resources and cost increase caused by discarding magnets in traditional disposable tissue boxes. This design not only meets the needs of daily use, but also embodies the dual advantages of environmental protection and economy, and has obvious improvements and contributions to the existing technology.

[0043] Example 2 The difference between this embodiment and the above-mentioned embodiment is that the fixing structure can be an elastic buckle structure in addition to the third easy-tear sealing tape 51. The elastic buckle structure includes elastic blocks arranged on both sides of the inner box 5 and corresponding card slots on both sides of the outer box 1. The elastic block is generally made of elastic materials such as rubber, and its shape can be trapezoidal or semicircular, etc., which is easy to be inserted into the card slot. The shape and size of the card slot match the elastic block. When the inner box 5 is inserted into the outer box 1, the elastic block automatically snaps into the card slot to achieve the fixing connection between the inner box 5 and the outer box 1. When the inner box 5 needs to be replaced, just squeeze the elastic block slightly to make it out of the card slot, and the inner box 5 can be easily taken out.

[0044] The implementation principle of this embodiment is that the elastic buckle structure is more convenient and quick to fix, and does not need to be torn and inserted like the third easy-tear sealing tape 51. When replacing the inner box 5, the disassembly and installation can be completed more quickly, which improves the convenience of use. At the same time, the elastic buckle structure can be reused many times, further enhancing the durability and economy of the tissue box, and compared with the traditional disposable tissue box, it has significant improvements in environmental protection and cost control.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
