Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a packaging liner and packaging component. Background Technology

[0002] Currently, most packaging boxes are made of folded cardboard, and often have an inner lining to hold the product inside. This lining helps to contain the product and separate it from the box, thus providing better protection. To make the lining and the cardboard box more aesthetically pleasing, they are generally made of the same material, meaning they are also made of folded cardboard to directly hold the product.

[0003] In related technologies, three plates are folded together to form a groove, which is used to store the product. To prevent the product from sliding along the groove's extension direction, baffle structures are placed at both ends of the groove to seal its opening, causing the inner lining structure to form a frame structure at the groove, blocking all sides of the product. Because the sides of the product are blocked, it is difficult to access the sides of the product when it needs to be removed, increasing the difficulty of retrieving the product. Utility Model Content

[0004] This utility model provides a packaging liner and packaging component for restricting product movement and reducing the difficulty of removing the product.

[0005] This utility model provides a packaging liner, which includes a main body formed by folding the same plate-shaped material or the same sheet-shaped material; the main body includes a first side plate, a support plate, and a second side plate, the first side plate, the support plate, and the second side plate being connected sequentially along a first direction to form a receiving groove for storing products; the support plate includes a first extension portion extending out of the first side plate along a second direction; the main body also includes a third side plate and a fourth side plate, the third side plate, the first extension portion, and the fourth side plate being connected sequentially along the first direction to form a first adjusting groove communicating with the receiving groove in a second direction, the second direction being perpendicular to the first direction; wherein, at least one of the third side plate and the fourth side plate is located between the first side plate and the second side plate.

[0006] In one embodiment, the receiving groove has an opening on the side facing the first adjusting groove, and the third side plate and the fourth side plate extend outward from the opening along a second direction.

[0007] In one embodiment, the support plate further includes a second extension at the end away from the first extension, and the main body further includes a fifth side plate and a sixth side plate. The fifth side plate, the second extension, and the sixth side plate are connected sequentially along a first direction to form a second adjustment groove that communicates with the receiving groove in a second direction. At least one of the fifth side plate and the sixth side plate is located between the first side plate and the second side plate.

[0009] In one embodiment, the first side plate and the third side plate are connected to the same side of the support plate in a first direction, and the first side plate and the third side plate are parallel; the second side plate and the fourth side plate are connected to the same side of the support plate in a second direction, and the second side plate and the fourth side plate are parallel.

[0010] In one embodiment, the packaging liner further includes a first locking plate connected to a support plate; the main body further includes a first folding plate, a first side plate and a third side plate respectively connected to the same side of the first folding plate, the side of the first folding plate away from the first side plate being detachably locked with the first locking plate, such that the side of the first folding plate away from the first side plate abuts against the side of the support plate away from the receiving groove, and the first side plate, the third side plate, the first folding plate and the support plate form a first buffer cavity.

[0011] In one embodiment, the first locking plate has a first slot. When the first locking plate is in a locked engagement state, the first slot is perpendicular to the support plate, so that the end of the first folding plate inserted into the first slot is perpendicularly held against the support plate.

[0012] In one embodiment, the packaging liner further includes a second locking plate connected to the end of the support plate away from the first locking plate; the first folding plate is configured to lock into the second locking plate simultaneously when locked into the first locking plate.

[0013] In one embodiment, the main body further includes a second folding plate, and a second side plate and a fourth side plate are respectively connected to the same side of the second folding plate. The side of the second folding plate away from the second side plate is used to detachably lock and engage with the first locking plate, such that the side of the second folding plate away from the second side plate abuts against the side of the support plate away from the receiving groove.

[0039] The present invention will be further described below with reference to the accompanying drawings.

[0040] See Figures 1 to 3 As shown, in a first aspect, the present invention provides a packaging liner 1, which includes a main body 11 formed by folding the same plate-shaped material or the same sheet-shaped material. The main body 11 includes a first side plate 112, a support plate 111, a second side plate 113, a third side plate 114, and a fourth side plate 115.

[0041] The first side plate 112, the support plate 111, and the second side plate 113 are connected sequentially along the first direction to form a receiving groove 12. In use, the product 3 can be placed in the receiving groove 12, and the support plate 111 supports the product 3 (see...). Figure 5 The first side plate 112 and the second side plate 113 are used to prevent the product 3 from moving along the first direction. The receiving groove 12 extends along the second direction, which is perpendicular to the first direction.

[0042] The support plate 111 includes a first extension 1112 extending in a second direction from the first side plate 112 (for ease of understanding, in...). Figure 3 The diagram shows a dashed line separating the support portion 1111 and the first extension portion 1112. The third side plate 114, the first extension portion 1112, and the fourth side plate 115 are sequentially connected along the first direction to form a first adjustment groove 13, which is connected to the receiving groove 12 in the second direction. One side of the product 3 in the second direction can be exposed to the outside through the first adjustment groove 13. When it is necessary to remove the product 3 from the receiving groove 12, the product 3 can be directly contacted by inserting it into the receiving groove 12, reducing the difficulty of removing and storing the product 3. The support plate 111 includes a support portion 1111 connected to the first side plate 112 and the second side plate 113, which supports the product 3.

[0043] Furthermore, since one of the plates forming the first adjustment groove 13 is the first extension 1112 of the support plate 111, and the support plate 111 is used to fit against the bottom surface of the product 3, the bottom edge of the product 3 can be exposed at the first adjustment groove 13. When a finger is inserted into the first adjustment groove 13, the finger can directly contact the bottom edge of the product 3, thus making it easier to separate the product 3 from the support plate 111 to insert the finger under the bottom surface of the product 3. Compared to only being able to contact the upper area of ​​the side of the product 3, it is easier to remove the product 3.

[0044] At least one of the third side plate 114 and the fourth side plate 115 will be located between the first side plate 112 and the second side plate 113, thereby reducing the opening of the receiving groove 12. The product 3 is blocked by the third side plate 114 or the fourth side plate 115, preventing the product 3 from moving toward the first adjustment groove 13 and ensuring the stability of the product 3 during transportation.

[0045] This can be achieved by having only the third side plate 114 located between the first side plate 112 and the second side plate 113, and the fourth side plate 115 overlapping with the second side plate 113, or by having the fourth side plate 115 located on the side of the second side plate 113 away from the first side plate 112.

[0046] Alternatively, the fourth side plate 115 may be located between the first side plate 112 and the second side plate 113, and the third side plate 114 may be arranged to overlap with the first side plate 112, or the third side plate 114 may be located on the side of the first side plate 112 away from the second side plate 113.

[0047] Alternatively, the third side plate 114 and the fourth side plate 115 may both be located between the first side plate 112 and the second side plate 113.

[0048] The above-mentioned various settings are mainly adjusted by adjusting the shape of the first extension 1112 along the first direction.

[0049] See Figure 1 and Figure 2 As shown, the third side plate 114 and the fourth side plate 115 are both located between the first side plate 112 and the second side plate 113. The third side plate 114 and the fourth side plate 115 simultaneously block the product 3, improving the stability of the positioning. Furthermore, by separating the same opening with two side plates, the opening of the receiving groove 12 towards the first adjusting groove 13 can be divided into three smaller openings, avoiding the situation where a single opening is too large.

[0050] In some implementations, in order to better restrict the movement of product 3 in the second direction, when the third side plate 114 and the fourth side plate 115 are disposed between the first side plate 112 and the second side plate 113, the spacing between the first side plate 112, the second side plate 113, the third side plate 114 and the fourth side plate 115 can be controlled so that the third side plate 114 and the fourth side plate 115 divide the opening of the receiving groove 12 into three equal parts, so that the force on the third side plate 114 and the fourth side plate 115 is approximately the same, and the side plates are prevented from deforming due to force concentration.

[0051] When the opening of the receiving groove 12 toward the first adjustment groove 13 is separated by one of the third side plate 114 and the fourth side plate 115, the opening of the receiving groove 12 toward the first adjustment groove 13 can be divided into two equal parts by one of the third side plate 114 and the fourth side plate 115, so that the forces on both sides of the side plate blocking the receiving groove 12 are approximately the same.

[0052] See Figures 1 to 3 As shown, the receiving groove 12 has an opening on the side facing the first adjusting groove 13, and the third side plate 114 and the fourth side plate 115 extend outward from the opening in the second direction. In other words, when the product is placed in the receiving groove 12, the end face of the product can be directly contacted by the third side plate 114 or the fourth side plate 115 extending from the opening, thus preventing the product 3 from moving in the second direction.

[0053] See Figure 1 as well as Figure 3As shown, the support plate 111 also includes a second extension 1113 at the first extension away from the first extension 1112. The main body 11 includes a fifth side plate 116 and a sixth side plate 117. The fifth side plate 116, the second extension 1113 and the sixth side plate 117 are connected sequentially along the first direction to form a second adjustment groove 14 that communicates with the receiving groove 12 in the second direction. At least one of the fifth side plate 116 and the sixth side plate 117 positions the receiving groove 12 between the first side plate 112 and the second side plate 113.

[0054] In other words, the side of product 3 away from the first adjustment groove 13 can be exposed to the external environment through the second adjustment groove 14. When it is necessary to remove product 3 from the receiving groove 12, a finger can be inserted through the first adjustment groove 13 to touch one side of product 3, and a finger can be inserted through the second adjustment groove 14 to touch the other side of product 3. Product 3 can be removed from the receiving groove 12 by clamping the opposite sides of product 3.

[0055] Similar to the first adjustment groove 13, since at least one of the fifth side plate 116 and the sixth side plate 117 is located between the first side plate 112 and the second side plate 113, the product 3 can be prevented from moving into the second adjustment groove 14 by using the fifth side plate 116 or the sixth side plate 117 to block the product 3, thereby improving the stability of the product 3 during transportation.

[0056] See Figure 3 as well as Figure 4 As shown, in some implementations, a first crease 151 is formed between the first side plate 112 and the support plate 111, a second crease 152 is formed between the second side plate 113 and the support plate 111, a third crease 153 is formed between the third side plate 114 and the support plate 111, and a fourth crease 154 is formed between the fourth side plate 115 and the support plate 111. The first crease 151, the second crease 152, the third crease 153, and the fourth crease 154 are parallel to each other and all extend along a second direction.

[0057] Since the creases formed by each side panel and the support plate 111 are parallel to each other, the folding directions of the first side panel 112, the second side panel 113, the third side panel 114 and the fourth side panel 115 relative to the support plate 111 are the same. When unfolded, the first side panel 112, the second side panel 113, the third side panel 114 and the fourth side panel 115 are all unfolded along the first straight line direction, and there will be no overlap or gaps in the unfolded panels. Compared with setting intersecting creases, which makes each side panel unfold in different directions, the length of the unfolded panel in the second direction is reduced, thereby reducing the amount of cardboard used and lowering the cost.

[0058] In some implementations, a fifth crease 155 is formed between the fifth side panel 116 and the support plate 111, and a sixth crease 156 is formed between the sixth side panel 117 and the support plate 111. The fifth crease 155 and the sixth crease 156 are parallel, and the fifth crease 155 is parallel to the first crease 151. That is, the first crease 151, the second crease 152, the third crease 153, the fourth crease 154, the fifth crease 155, and the sixth crease 156 are parallel to each other. This allows the fifth crease 155 and the sixth crease 156 to unfold along the first direction, avoiding the need to lengthen the second direction, thereby reducing the amount of cardboard used and lowering costs.

[0059] Understandably, in other implementations, the shape of the support plate 111 can be adjusted so that the first crease 151 and the second crease 152 are set at an acute angle, thereby forming a receiving groove 12 with a conical groove structure. Alternatively, the third crease 153 and the fourth crease 154 can be set at an acute angle, thereby forming a first adjusting groove 13 with a conical groove structure. When the creases are set at an acute angle, the unfolding directions between the first side plate 112 and the second side plate 113 will be in different directions, resulting in an irregular shape in the unfolded state, which leads to more waste during the cutting of the sheet metal and increases the cost of the main body 11.

[0060] See Figure 1 as well as Figure 3 As shown, in some implementations, the first side plate 112 and the third side plate 114 are connected to the same side of the support plate 111 in the first direction, and the first side plate 112 and the third side plate 114 are parallel; the second side plate 113 and the fourth side plate 115 are connected to the same side of the support plate 111, and the second side plate 113 and the fourth side plate 115 are parallel.

[0061] By arranging the plates in parallel, the opening shape of the receiving groove 12 corresponds to the opening shape of the first adjusting groove 13, thus improving the aesthetics of the packaging liner 1.

[0062] Understandably, in some implementations, the first side plate 112, the second side plate 113, the third side plate 114, and the fourth side plate 115 are all perpendicular to the support plate 111. This forms a receiving groove 12 with a rectangular cross-section and a first adjusting groove 13 with a rectangular cross-section.

[0063] In other implementations, the first side plate 112 and the second side plate 113 may be set at an obtuse angle relative to the support plate 111, so that the cross-section of the receiving groove 12 is a trapezoidal structure, and the cross-section of the first adjusting groove 13 is also a trapezoidal cross-section.

[0064] See Figures 1 to 3As shown, in some implementations, the packaging liner 1 further includes a first locking plate 16, which is connected to the support plate 111; the main body 11 also includes a first folding plate 118, with the first side plate 112 and the third side plate 114 respectively connected to the same side of the first folding plate 118. The side of the first folding plate 118 away from the first side plate 112 is detachably locked to the first locking plate 16, such that the side of the first folding plate 118 away from the first side plate 112 abuts against the side of the support plate 111 away from the receiving groove 12, and the first side plate 112, the third side plate 114, the first folding plate 118 and the support plate 111 form a first buffer cavity 18.

[0065] Since the first side plate 112 and the third side plate 114 are both connected to the same side of the first folding plate 118, when the first folding plate 118 is locked, the first side plate 112 and the third side plate 114 can be moved simultaneously, and the movement of the first side plate 112 and the third side plate 114 can be restricted, thus avoiding cross-sectional deformation of the receiving groove 12 and the first adjusting groove 13 when locking.

[0066] Meanwhile, the first buffer chamber 18 can also be used to store various small accessories.

[0067] The fifth side plate 116 is also connected to the first folding plate 118, and the fifth side plate 116, the first side plate 112 and the third side plate 114 are connected to the same side of the first folding plate 118.

[0068] In addition, when the first folding plate 118 is locked in place with the locking plate, it also forms a first buffer cavity 18 with the first side plate 112, the third side plate 114, and the support plate 111. This cavity structure can improve the strength of the packaging liner 1, preventing deformation of the packaging liner 1 under impact and better protecting the product 3 in the receiving slot 12.

[0069] For details, see Figure 3 as well as Figure 4 As shown, the first folding plate 118 has three parallel creases that divide it into a first connecting plate portion 1181, a second connecting plate portion 1182, a third connecting plate portion 1183, and a fourth connecting plate portion 1184 connected in sequence. The first connecting plate portion 1181 is used to connect with the first side plate 112 and the second side plate 113. The creases formed between the connecting plate portions of the first folding plate 118 are parallel to each other. The first folding plate 118 can be folded by rolling it up, allowing the fourth connecting portion of the first folding plate 118 to be inserted into the slot of the first locking plate 16 and locked in place. Compared to locking from multiple directions, locking is simpler.

[0070] The creases of the first folding plate 118 are parallel to the first crease 151, the second crease 152, the third crease 153, and the fourth crease 154. The folding direction during the folding process is perpendicular to the first direction, making folding relatively simple. Moreover, after unfolding, it mainly extends in a single direction, resulting in a more regular shape of the unfolded main body 11. This minimizes wasted area when cutting the entire plate to form the main body 11, reducing the cost of the packaging liner 1.

[0071] Understandably, the number of creases on the first folding plate 118 can be increased or decreased appropriately. For example, the first folding plate can be set as a three-fold structure with two parallel creases, or a five-fold structure with four parallel creases.

[0072] The first locking plate 16 and the main body 11 can be integrally formed by folding together the same plate material or the same sheet material, or they can be fixed to the support plate 111 by adhesive bonding.

[0073] See Figure 3 As shown, in some implementations, the first locking plate 16 has a first slot 161. When the first locking plate 16 is in a locked engagement state, the first slot 161 is perpendicular to the support plate 111, so that the end of the first folding plate 118 inserted into the first slot 161 (the fourth connecting plate portion 1184 in the figure) abuts vertically against the support plate 111. That is, when the first folding plate 118 is locked with the first locking plate 16 to limit the deflection of the first side plate 112 and the third side plate 114 relative to the support plate 111, it also abuts vertically against the support plate 111, thereby improving the deformation resistance of the support plate 111.

[0074] In some other implementations, the slot of the first locking plate 16 can be set parallel to the support plate 111, so that the end of the first folding plate 118 inserted into the slot is parallel to or coincides with the support plate 111.

[0075] See Figure 1 as well as Figure 3 As shown, the first locking plate 16 is connected to the end of the first extension 1112 away from the second extension 1113. The slot of the first locking plate 16 can be made perpendicular to the support plate 111 by folding the first locking plate 16 downward.

[0076] It is understandable that in some other implementations, the first locking plate 16 can be directly glued to the bottom of the support plate 111, or the first locking plate 16 can be formed by providing a downwardly folded flange on the support plate 111.

[0077] See Figure 4As shown, in some implementations, the packaging liner 1 further includes a second locking plate 17, which is connected to the end of the support plate 111 away from the first locking plate 16, and the first folding plate 118 is configured to lock into the second locking plate 17 when locked into the first locking plate 16.

[0078] In other words, by setting locking structures at both ends of the support plate 111 to lock and engage with the first folding plate 118, the first folding plate 118 can be better fixed, preventing deformation of the first folding plate 118 and improving the seismic performance of the first buffer cavity 18.

[0079] In some implementations, a second slot 171 can be provided at the second locking plate 17, and the first folding plate 118 and the second locking plate 17 can be locked together by inserting the first folding plate 118 into the second slot 171.

[0080] Similar to the first locking plate 16, the second locking plate 17 and the main body 11 can be integrally formed by folding together the same plate material or the same sheet material, or they can be fixed to the support plate 111 by adhesive bonding.

[0081] See Figures 1 to 3 As shown, the main body 11 also includes a second folding plate 119. The second side plate 113 and the fourth side plate 115 are respectively connected to the same side of the second folding plate 119. The side of the second folding plate 119 away from the second side plate 113 is used to detachably lock with the first locking plate 16, so that the side of the second folding plate 119 away from the second side plate 113 abuts against the side of the support plate 111 away from the receiving groove 12. The second side plate 113, the fourth side plate 115, the first folding plate 118 and the support plate 111 form a second buffer cavity 19, and a part of the second folding plate 119 is in contact with the first folding plate 118.

[0082] In other words, the second folding plate 119 forms a second buffer cavity 19, which improves the shock resistance of the packaging liner 1. Furthermore, the second folding plate 119 is partially attached to the first folding plate 118, so that the first folding plate 118 and the second folding plate 119 support each other and prevent the first folding plate 118 from deforming.

[0083] Specifically, in the unfolded state of the second folding plate 119, the second folding plate 119 includes a fifth connecting plate portion 1191, a sixth connecting plate portion 1192, a seventh connecting plate portion 1193, and an eighth connecting plate portion 1194 arranged sequentially along the first direction. The second side plate 113, the fourth side plate 115, and the sixth side plate 117 are all connected to the fifth connecting plate portion 1191, while the eighth connecting plate portion 1194, which is away from the fifth connecting plate portion 1191, is locked in place with the first locking plate 16, so that the eighth connecting plate portion 1194 is inserted into the slot of the first locking plate 16 and vertically abuts against the bottom of the support plate 111. The eighth connecting plate portion 1194 is in contact with the fourth connecting plate portion 1184 of the first folding plate 118.

[0084] See Figure 1 as well as Figure 2 As shown, in some implementations, the second folding plate 119 is symmetrically arranged with the first folding plate 118, so that the formed first buffer cavity 18 and the second buffer cavity 19 are symmetrical. This can provide stable and reliable support for the support plate 111 and improve the stability of the packaging liner 1.

[0085] The second folding plate 119 can be inserted into the second slot 171 and locked with the second locking plate 17 while being locked with the first locking plate 16, thereby improving the stability of the second folding plate 119.

[0086] See Figures 6 to 8 As shown, in a second aspect, the present invention also provides a packaging component, which includes:

[0087] The box body 2 or the box body, and any of the above-mentioned packaging liners 1, wherein the packaging liners 1 are installed in the box body 2 or the box body.

[0088] Since the inner packaging liner 1 has a first side plate 112, a support plate 111 and a second side plate 113 connected in sequence, the first side plate 112, the support plate 111 and the second side plate 113 can be folded together to form a receiving groove 12 to accommodate the product 3, and the first side plate 112 and the second side plate 113 prevent the product 3 from moving along the first direction.

[0089] Furthermore, since the support plate 111 has a third side plate 114 and a fourth side plate 115 connected to its first extension 1112 extending from the first side plate 112 in the second direction, the third side plate 114, the first extension 1112, and the fourth side plate 115 can be folded sequentially to form a first adjustment groove 13 that communicates with the receiving groove 12 in the second direction. When it is necessary to remove the product 3 from the receiving groove 12, the contact area with the product 3 can be increased by inserting a finger into the first adjustment groove 13 to contact the side of the product 3, thereby reducing the difficulty of removing the product 3.

[0090] Furthermore, since at least one of the third side plate 114 and the fourth side plate 115 is located between the first side plate 112 and the second side plate 113, the product 3 can be restricted by at least one of the third side plate 114 and the fourth side plate 115, thereby limiting the product 3 in the second direction and improving the stability of the product 3 during transportation.

[0091] Placing the inner packaging liner 1 inside the box or container allows the inner packaging liner 1 to be protected by the box or container outside the inner packaging liner 1, preventing damage to the inner packaging liner 1 during transportation and improving the safety of transporting the product 3.

[0092] See Figure 9 As shown, the box body 2 or box body outside the inner packaging liner 1 can be made of cardboard folded together. After the box body 2 is folded, it forms a groove that matches the outer dimensions of the inner packaging liner 1. When the inner packaging liner 1 is placed in the groove, the sides of the inner packaging liner 1 are respectively attached to the side walls of the groove to prevent the inner packaging liner 1 from moving relative to the box body 2.

[0093] See Figure 7 as well as Figure 9 As shown, the box body 2 includes a frame structure 21, which includes a first upright plate 211, a second upright plate 212, a third upright plate 213, and a fourth upright plate 214 connected sequentially along the circumference. The first upright plate 211, the second upright plate 212, the third upright plate 213, and the fourth upright plate 214 respectively form the four side walls of the groove. Referring to the unfolded view of the box body 2, it can be seen that the fourth upright plate 214 has an adhesive plate 215 connected to it on the side away from the third upright plate 213. After folding, the adhesive plate 215 overlaps with the first upright plate 211. The relative movement of the first upright plate 211 and the fourth upright plate 214 can be prevented by bonding the adhesive plate 215 to the first upright plate 211.

[0094] join Figure 9 As shown, in some implementations, a first locking plate 22 is connected to the lower side of the first upright plate 211; a second locking plate 23 is connected to the lower side of the second upright plate 212; a third locking plate 24 is connected to the lower side of the third upright plate 213; and a fourth locking plate 25 is connected to the lower side of the fourth upright plate 214. The third locking plate 24 is provided with a locking groove. When the unfolded box 2 is folded, the four upright plates are folded sequentially to form a frame structure 21. Then, the third locking plate 24 is folded to the inside of the frame structure 21. Afterward, the second locking plate 23 and the fourth locking plate 25 are flipped to the inside of the frame structure 21, so that the second locking plate 23, the third locking plate 24, and the fourth locking plate 25 form a locking socket at the locking groove. At this point, by folding the first locking plate 22 to the inside of the frame structure 21 and inserting the end of the first locking plate 22 into the locking socket, the bottom of the box 2 can be locked.

[0095] In other implementations, the locking structure at the bottom of the housing 2 can be other structures, and is not limited to the locking structure shown in the figure.

[0096] See Figure 9 As shown, in some implementations, a first folding plate 27 is connected to the upper side of the third upright plate 213, and a first insertion port 271 is formed between the first folding plate 27 and the third upright plate 213. A cover plate 26 is also connected to the upper side of the first upright plate 211, and a second folding plate 261 is connected to the side of the cover plate 26 away from the first upright plate 211. When in use, the cover plate 26 is folded toward the first folding plate 27, and the second folding plate 261 is inserted into the first insertion port 271 to lock the cover plate 26.

[0097] In some implementations, the upper side of the second upright plate 212 is also connected to the first flap 28, and the upper side of the fourth upright plate 214 is also connected to the second flap 29. Before locking the cover plate 26, the first flap 28 and the second flap 29 can be folded inward to avoid the gap between the cover plate 26 and the second upright plate 212 or the fourth upright plate 214 being too large, which would expose the packaging liner 1 or the product 3.

[0098] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
