Description

Technical area

[0001] The present disclosure relates to a protective case for an ink cartridge and an ink cartridge package. State of the art

[0002] Ink cartridges used in everyday office life also include ink cartridges with print heads. The ink in the ink cartridge creates a pattern on the paper via the print head according to the printer's instructions. The print head in the ink cartridge is a high-precision component and must be protected during daily transport. Prior art document CN206749276U discloses the use of a protective card clip for the ink cartridge's print head. This clip is cumbersome to use, requires considerable force to remove from the ink cartridge, and is expensive. Another prior art document CN219947661U discloses the use of a packaging case for an ink cartridge with a print head. The overall shape of the case conforms to the circumference of the ink cartridge, and a free space is provided at the position of the ink cartridge's print head to protect the ink cartridge's print head.However, using these two protective casings to protect the print head still poses a risk of the ink cartridge tipping over, which compromises the protective effect. Furthermore, both solutions use a plastic structure to protect the print head, which does not meet environmental protection requirements. Disclosure of the utility model

[0003] The technical problem to be solved by the present disclosure is to overcome the defect of the above-mentioned ink cartridge in the prior art in which protection is impaired by tipping over of the ink cartridge, and to provide a protective case for the ink cartridge and an ink cartridge package.

[0004] The present disclosure solves the above-mentioned technical problem by the following technical solutions: A protective housing for an ink cartridge is provided, the ink cartridge comprising a cartridge body and a print head, the print head protruding from a portion of the bottom surface of the cartridge body, the protective housing comprises a receiving portion and a support portion connected to the receiving portion, wherein the receiving portion has a first receiving space for receiving the cartridge body and a second receiving space for receiving the print head, wherein the first receiving space is connected to the second receiving space; the support portion extends along the height direction of the ink cartridge and is arranged near the second receiving space so that the other area of ​​the bottom surface of the cartridge body abuts against the support portion; at least a part of the lower edge of the support portion is flush with the lower edge of the second receiving space; and in the height direction of the ink cartridge, the lower edge of the second receiving space is lower than the front surface of the print head.

[0005] Because the support section in this solution rests on the other area of ​​the bottom surface of the cartridge body, excluding the print head, along the height direction of the ink cartridge, and at least a portion of the lower edge of the support section is flush with the lower edge of the second receiving space, the protective housing can provide support both in the print head area and in the other area of ​​the ink cartridge, thereby preventing the ink cartridge from tipping over. Furthermore, the lower edge of the second receiving space is lower than the front surface of the print head, leaving a gap between the print head and the lower edge of the protective housing, thus protecting the print head.

[0006] Preferably, in the protective case, the receiving portion and the supporting portion are formed by folding a sheet body, wherein the supporting portion is formed by folding a partial structure of the sheet body inward in a direction close to the second receiving space.

[0007] The fact that the protective housing in this solution is formed by folding the sheet body, wherein the support portion can be formed by folding a partial structure of the sheet body inward, facilitates the manufacture and molding of the protective housing. Preferably, the sheet body comprises a plurality of plate bodies arranged in succession, wherein a head-end plate body arranged at a head end is connectable to a tail-end plate body arranged at a tail end; at least one of the plurality of plate bodies has an inwardly folded portion, wherein a cut is arranged between the inwardly folded portion and the other portion of the plate body.

[0008] In this solution, the head-end plate body and the tail-end plate body, after being connected, can enclose the receiving space for receiving the ink cartridge.

[0011] Preferably, the blade body further comprises a connecting plate body, the connecting plate body being located on one side of one of the head-end plate body and the tail-end plate body and being bonded to the other.

[0012] Preferably, the protective housing is formed by pressing in a mold.

[0013] Preferably, the projection of the support portion on the bottom surface of the cartridge body has an L-shape.

[0014] The protective housing is preferably made of paper or plastic material.

[0015] With this solution, it's beneficial for environmental protection if the sheet body is made of paper. It can also be practical to print the required information on the surface of the protective casing, such as local environmental protection logos corresponding to different sales locations. If the sheet body is made of plastic, the plastic can be transparent, allowing easy observation of the ink cartridge, for example, the part of the ink cartridge surface where information is recorded.

[0016] Preferably, the distance between the lower edge of the second receiving space and the front surface of the print head is in the range of 6 mm to 10 mm.

[0017] Preferably, the upper dimension of the first receiving space is smaller than the dimension of the flange on the top of the ink cartridge.

[0018] With this solution, the upper edge of the protective housing can additionally support the flange on top of the ink cartridge, thereby further improving the protective effect. Preferably, a groove is provided on the top of the receiving portion, which groove is used to accommodate a locking structure for the ink cartridge.

[0019] With this solution, the groove can support the locking structure of the ink cartridge, thereby further improving the protective effect of the protective casing.

Detailed description of embodiments

[0025] The present disclosure will be further described below with reference to embodiments, but the present disclosure is not limited to the scope of the embodiments mentioned. Example 1

[0026] The embodiments of the present disclosure provide a protective housing 10 for an ink cartridge 20. As shown in Fig. 1, the ink cartridge 20 comprises a cartridge body 21 and a print head 22. In the height direction H of the ink cartridge 20, the print head 22 protrudes from a portion of the bottom surface of the cartridge body 21 and is located on one side of the bottom surface of the cartridge body 21 (left in the length direction L, see Fig. 1). As a result, the ink cartridge 20 has an uneven structure on its underside, with the protruding portion representing the area where the print head 22 is located, while the other area except the print head 22 has a concave structure. Typically, the other area 201 of the bottom surface of the cartridge body is a substantially flat surface. As shown in Fig. 4, the top of the cartridge body 21 is connected to a top cover 23, and the top cover 23 is fixed to the cartridge body 21 by welding or gluing.

[0027] As in the Fig. 2 to 6, the protective housing 10 comprises a receiving section 100 and a support section 200 connected to the receiving section 100, wherein the receiving section 100 has a first receiving space 110 for receiving the cartridge body 21 and a second receiving space 120 for receiving the print head 22, wherein the first receiving space 110 is connected to the second receiving space 120; the support section 200 extends along the height direction H of the ink cartridge 20 and is arranged close to the second receiving space 120 such that the other region 201 of the bottom surface of the cartridge body rests against the support section; at least a part of the lower edge 211 of the support section 200 is flush with the lower edge 121 of the second receiving space; and in the height direction H of the ink cartridge 20, the lower edge 121 of the second receiving space is lower than the end face of the print head 22.

[0028] In the Fig. 2 to 6, the first receiving space 110 is located above the second receiving space 120. The first receiving space 110 encloses the outer wall of the cartridge body 21. The depth of the first receiving space 110 and the dimension of the cartridge body 21 in the height direction H of the ink cartridge 20 can be dimensioned as required. In some cases, the depth of the first receiving space 110 is greater than the dimension of the cartridge body 21 in the height direction H of the ink cartridge 20, in other cases the depth is smaller. As shown in the Fig. 3, Fig. 4 and Fig. 5, the depth of the first receiving space 110 is preferably basically equal to the dimension of the cartridge body 21 in the height direction H of the ink cartridge 20. If the cartridge body 21 has a flange 202 on the top side, the depth is slightly less than the dimension of the cartridge body 21 in the height direction H of the ink cartridge 20.

[0029] As in the Fig. 2 to 6, the second receiving space 120 encloses the outside of the print head 22. The depth of the second receiving space 120 is greater than the dimension of the print head 22 in the height direction H of the ink cartridge 20, so that a distance D remains between the print head 22 and the bottom edge 121, thereby protecting the print head 22. In addition, the distance D can also serve as a buffer during transportation or dropping. Even if the bottom edge of the protective case 10 is deformed, the print head 22 will not be damaged due to the distance D. The support portion 200 rests on the other area 201 of the bottom surface of the cartridge body, and at least a part of the bottom edge 211 of the support portion 200 is flush with the bottom edge 121 of the second receiving space, so that the bottom edge of the protective case 10 can be stably placed, which in turn enables free-floating storage of the ink cartridge 20.Preferably, almost the entire lower edge 211 of the support section 200 is flush with the lower edge 121 of the second receiving space, as shown in . Fig. 4. In other embodiments, a portion of the lower edge of the support portion 200 may be higher than the lower edge 121 of the second receiving space.

[0030] The above-provided structural shape of the protective case 10 for the ink cartridge 20 is also advantageous for the realization of manufacturing and molding. In the protective case 10, the receiving portion 100 and the support portion 200 can be formed by folding a sheet body 300, and the support portion 200 is formed by folding a partial structure of the sheet body 300 inward in a direction near the second receiving space 120.

[0031] The sheet body 300 is made of paper or plastic. When the sheet body 300 is made of paper, it is beneficial for environmental protection, especially in many countries where there are restrictions on plastics, and it is also advantageous in terms of cost. Furthermore, it can also be convenient to print the necessary information on the surface of the protective case 10, such as the local environmental protection logos corresponding to different sales locations. When the sheet body 300 is made of plastic, the plastic material can be transparent so that the ink cartridge 20, for example, the part of the surface of the ink cartridge 20 on which its information is recorded, can be easily observed.

[0032] The sheet body 300 comprises a plurality of plate bodies arranged sequentially, wherein a head-end plate body arranged at a head end is connectable to a tail-end plate body arranged at a tail end; at least one of the plurality of plate bodies has an inwardly folded portion, wherein a cut 350 is arranged between the inwardly folded portion and the other portion of the plate body. The number of plate bodies depends on the number of peripheral side walls of the ink cartridge 20. As a conventional form of the ink cartridge 20, as shown in Fig. 1, the ink cartridge 20 has four peripheral sidewalls. Accordingly, the sheet body 300 may include four main plate bodies corresponding to the peripheral sidewalls of the ink cartridge 20. When the head-end plate body is connected to the tail-end plate body, the accommodating space formed by enclosing can be adapted to the structure of the ink cartridge 20. The sheet body 300 may be a one-piece sheet structure, and folds may be provided between the plate bodies. A fold may also be provided between the inwardly folded portion and the other portion of the plate body, outside the cut 350, to facilitate folding the sheet body 300 to form the protective case 10.

[0033] When one or more plate bodies are selected from the plurality of plate bodies to form the inwardly folded portion, the selection may be made based on the positional relationship of the above-mentioned concave part of the ink cartridge 20, and the plate body corresponds to the concave part in the height direction H and length direction L of the ink cartridge 20 or in the height direction H and width direction W of the ink cartridge 20. Moreover, the dimension of the inwardly folded portion on these respective plate bodies may be set with respect to the dimension of the concave part of the ink cartridge 20. A cut 350 is provided between the inwardly folded portion and the other portion so that the inwardly folded portion can be separated from the other portion at the cut 350 and folded inward.As a result, the other region 201 of the bottom surface of the cartridge body can rest against the support section 200 formed by folding the inwardly folded section inwards, and the second receiving space 120 can also be defined by folding the inwardly folded section inwards.

[0034] In the plate body having the inwardly folded portion, the plate body is provided with the cut 350 at a position corresponding to the bottom surface of the cartridge body 21. By arranging the cut 350 at the position corresponding to the bottom surface of the cartridge body 21, on the one hand, the inwardly folded portion can correspond to the height of the bottom surface of the cartridge body 21, and on the other hand, because there is no cut 350 in the other area, the inwardly folded portion can remain connected to the other portion of the plate body, thereby making the load-bearing capacity of the support portion 200 more reliable.

[0035] Using the example of the ink cartridge 20 with four circumferential side walls, Fig. 7 a structural shape of the plate body 300. After being enclosed and folded inwards, the sheet body 300 can take the shape of the Fig. 2 shown protective housing 10. And as shown in the Fig. 3 to 6, the sheet body can be arranged on the peripheral outer side of the ink cartridge 20 to protect the ink cartridge 20. The sheet body 300 includes a first plate body 310, a second plate body 320, a third plate body 330, and a fourth plate body 340 arranged sequentially, wherein the first plate body 310 at the head end is connectable to the fourth plate body 340 at the tail end. The third plate body 330 and the fourth plate body 340 are each provided with an inwardly folded portion, namely a first inwardly folded portion 331 and a second inwardly folded portion 341, respectively. A cut 350 is arranged between the first inwardly folded portion 331 and the other portion of the third plate body 330, and between the second inwardly folded portion 341 and the other portion of the fourth plate body 340.

[0036] As in the Fig. 3 to 5, the dimensions of the first plate body 310 and the third plate body 330 are dimensioned to correspond to the length of the ink cartridge 20, and the dimensions of the second plate body 320 and the fourth plate body 340 are dimensioned to correspond to the width of the ink cartridge 20. Between the first inwardly folded portion 331 and the other portion of the third plate body 330, a cut 350 is arranged only at a position corresponding to the bottom surface of the ink cartridge 20, and between the second inwardly folded portion 341 and the other portion of the fourth plate body 340, a cut 350 is arranged only at a position corresponding to the bottom surface of the ink cartridge 20. These two cuts 350 are in line. As shown in Fig. As shown in Fig. 7, a fold extending along the height direction H of the ink cartridge 20 is arranged between each two adjacent plate bodies of the first plate body 310, the second plate body 320, the third plate body 330, and the fourth plate body 340; a fold extending along the height direction H of the ink cartridge 20 is arranged between the inwardly folded portions and the other portions of the corresponding third plate body 330 and the fourth plate body 340.

[0037] As a means for connecting the head-end plate body to the tail-end plate body, the blade body 300 further comprises a connecting plate body 360, wherein the connecting plate body 360 is located on one side of one of the head-end plate body and the tail-end plate body and is bonded to the other. As shown in Fig. As shown in Figure 7, the connecting plate body 360 is located on one side of the first plate body 310, and a fold extending along the height direction H of the ink cartridge 20 is arranged between the connecting plate body and the first plate body 310. The connecting plate body 360 serves to be bonded to the fourth plate body 340.

[0038] The dimension of the first inwardly folded portion 331 in the third plate body 330 and the dimension of the second inwardly folded portion 341 in the fourth plate body 340 are both smaller than the plate bodies 330, 340 themselves. In particular, the first inwardly folded portion 331 is formed in its height such that it ends at the level of the bottom surface of the cartridge body 21, and its width is smaller than the width of the third plate body 330 in order to keep the plate body portion required for the second receiving space 120 free; the second inwardly folded portion 341 is formed in its height such that it ends at the level of the bottom surface of the cartridge body 21, and its width is preferably smaller than the width of the fourth plate body 340, as in Fig. 6, so that the bottom surface of the cartridge body 21 can be supported at several locations.

[0039] As in Fig. 6, the joint projection of the first inwardly folded portion 331 and the second inwardly folded portion 341 on the bottom surface of the cartridge body 21 has an L-shape. Depending on requirements, the projection of the inwardly folded portion on the bottom surface of the cartridge body 21 may also have other shapes. For example, as shown in Fig. 8, an L-shaped support portion 200 is formed at each of the two corners of the protective housing 10. When using a paper material as the sheet body 300, the entire length of the inwardly folded portion is related to the used portion of the sheet body 300. When using plastic as the sheet body 300, other shapes, such as a Z-shape (not shown in the figures), are possible in addition to the above-mentioned shape.

[0040] As in the Fig. 1 and Fig. 3, the ink cartridge 20 has a flange 202 on the top side, more precisely, a flange 202 is arranged on the outer top side of the cartridge body 21 in the circumferential direction. The dimension of the first receiving space 110 corresponds substantially to the circumferential size of the cartridge body 21. As shown in the Fig. 3 and Fig. 4, the upper dimension of the first receiving space 110 is smaller than the dimension of the flange 202 on the top of the ink cartridge 20. The upper edge 111 of the protective housing 10 can additionally support the flange 202 on the top of the ink cartridge 20, thereby further improving the protective effect.

[0041] As in the Fig. 1 and Fig. 3, the ink cartridge 20 further includes a locking structure 203 on the top side, and the locking structure 203 can be supported to further improve the supporting effect. In particular, as shown in Fig. 2, a groove 130 is arranged on the top side of the receiving portion 100, and the groove 130 is used to receive the locking structure 203 of the ink cartridge 20. The locking structures 203 of different ink cartridges 20 may be different. As shown in the Fig. 1 and Fig. 2, the locking structures 203 are located on two opposite sides of the ink cartridge 20, although one or more locking structures 203 may be arranged on the same side. Accordingly, grooves 130 are arranged at positions corresponding to the locking structures 203. In other embodiments, the ink cartridge 20 is provided with the locking structure 203 on only one side.

[0042] The groove 130 is preferably recessed downward from the upper edge 111 of the receiving portion 100. In other embodiments, the groove 130 may also penetrate the plate body at the top of the receiving portion 100 to form a support at the bottom of the groove 130 and a boundary at the top of the groove 130.

[0043] The distance D between the lower edge 121 of the second receiving space and the front surface of the print head 22 is in the range of 6 mm to 10 mm. The distance D can be adjusted according to the weight of the ink cartridge 20, the support of the upper edge 111 of the protective casing 10 on the flange 202 on the top of the ink cartridge 20, and the support of the groove 130 on the locking structure 203.

[0044] As in Fig. 1, a component carrying the identity information of the ink cartridge 20, typically a QR code 24 of the ink cartridge, is typically located on the surface of the ink cartridge 20. The QR code 24 is typically located at the end of the ink cartridge 20. By scanning the QR code 24, information such as the manufacturing date, batch, and ink type of the ink cartridge 20 can be retrieved. As shown in the Fig. 2 and Fig. 3, the receiving portion 100 is provided with a window 140 on the side wall of the first receiving space. The window 140 is arranged on the side wall such that it faces the component that carries the identity information of the ink cartridge 20. As shown in Fig. 7, the fourth plate body 340 has the window 140 on the top side. Example 2
