Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, a double-ended ink bag for a fountain pen includes an ink bag body, which includes a first ink bag 1 and a second ink bag 2, both of which are in a shape of a circular tube and have the same specification; one end of the first ink bag 1 is provided with a first inserting tube 101 used for being connected with a pen, a first sealing film 102 is arranged in the first inserting tube 101 in a sealing mode, the other end of the first ink bag 1 is provided with a tubular inserting part 103, the inner wall of the inserting part 103 is flush with the inner wall of the first ink bag 1, the thickness of the side wall of the inserting part 103 is half of that of the first ink bag 1, and a second sealing film 105 is arranged at one end, far away from the first ink bag 1, of the inserting part 103 in a sealing mode; one end of the second ink bag 2 is provided with a second insertion tube 201 used for being connected with a pen, a third sealing film 202 is arranged in the second insertion tube 201 in a sealing mode, the other end of the second ink bag 2 is provided with a circular tube-shaped bearing part 203, the outer wall of the bearing part 203 is flush with the outer wall of the first ink bag 1, the thickness of the side wall of the bearing part 203 is half of that of the first ink bag 1, and a fourth sealing film 204 is arranged in the bearing part 203 in a sealing mode; the calibers of the first cannula 101 and the second cannula 201 are not the same, one is 3.4mm, and the other is 2.6 mm; the insertion part 103 is insertable into the inside of the receptacle part 203, and the first ink bag 1 and the second ink bag 2 are connected together by the assembly fit of the insertion part 103 and the receptacle part 203.
Through the technical scheme, when only one pen is used, the inserting part 103 is firstly pulled out of the bearing part 203 to separate the first ink sac 1 and the second ink sac 2, then the second sealing film 105 on the inserting part 103 is torn off, then the inserting part 103 is inserted into the bearing part 203 again to enable the first ink sac 1 and the second ink sac 2 to be combined together again, then the first inserting tube 101 or the second inserting tube 201 is selected to be connected with the pen according to the ink sac caliber required by the pen, after the connection, force is applied to the ink sac which is not connected with the pen to enable the inserting part 103 to gradually penetrate into the bearing part 203, the end part of the inserting part 103 gradually approaches the fourth sealing film 204 and finally the fourth sealing film 204 is poked, at the moment, the sealing effect of the fourth sealing film 204 is lost (as shown in figure 3), the ink in the first ink sac 1 and the second ink sac 2 at the moment flows mutually, the two ink sacs are combined into a whole, forming a whole ink bag, of course, the fourth sealing film 204 can not be punctured first, and the ink bag connected with a pen can be punctured when no ink exists;
when two pens of different types (the calibers of the ink bags required by the two pens are respectively 3.4mm and 2.6mm) need to be installed with the ink bags at the same time, the inserting part 103 can be pulled out of the bearing part 203, so that the first ink bag 1 and the second ink bag 2 are disassembled, the second sealing film 105 and the fourth sealing film 204 respectively seal the first ink bag 1 and the second ink bag 2, ink leakage in the installation process is prevented, and the first ink bag 1 and the second ink bag 2 can be respectively installed in the two pens at the moment, so that the use requirements are met;
it should be noted that the first cannula 101, the second cannula 201, the first sealing film 102, and the third sealing film 202 are all in the prior art, and the existing ink bag has these structures, so detailed descriptions of their specific structures and their connection structures with the pen are omitted in this embodiment.
Further, as shown in fig. 1 to 3, an annular groove 104 is formed in one end, close to the second sealing film 105, of the outer wall of the insertion portion 103, after the insertion portion 103 and the receiving portion 203 are combined, a cavity is formed between the insertion portion 103 and the receiving portion 203 due to the formation of the annular groove 104, and the cavity provides a space for bending deformation after the fourth sealing film 204 is pierced (as shown in fig. 3), so that the piercing process of the fourth sealing film 204 is smoother and smoother.
Further, as shown in fig. 1-2, one end of the outer wall of the insertion part 103, which is close to the first ink bag 1, is hooped with a limiting ring 3, the limiting ring 3 can be freely peeled off, the limiting ring 3 plays a role in limiting the insertion part 103 and the carrying part 203, the fourth sealing film 204 is prevented from being punctured in advance, before the fourth sealing film 204 is punctured, the limiting ring 3 needs to be peeled off first, and thus the insertion part 103 can be smoothly inserted into the deepest part of the carrying part 203 without being blocked by the limiting ring 3.
Further, as shown in fig. 4, a tearing portion 205 is embedded in the fourth sealing film 204, the tearing portion 205 is cross-shaped, the center of the tearing portion 205 is located at the center of the fourth sealing film 204, the thickness of the tearing portion 205 is preferably one third of that of the fourth sealing film 204, the tearing portion 205 is more fragile and easier to tear than the fourth sealing film 204, and the fourth sealing film 204 can be pierced more quickly and smoothly by using the tearing portion 205 as a piercing point in the process of piercing the fourth sealing film 204.
Furthermore, the outer wall of the inserting part 103 and the inner wall of the bearing part 203 are provided with mutually matched threads (not shown in the figure), and the thread matching structure has the advantage of reliability and firmness.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
