Description

Technical Field

[0001] This utility model relates to the field of ink bottle sealing technology, and in particular to an ink bottle sealing structure. Background Technology

[0002] A printer ink bottle is a container used to store ink, typically used in inkjet printers. To prevent ink leakage during transportation or storage, ink bottles are usually equipped with a sealing cap. Before use, the sealing cap must be opened, and the entire ink bottle should be inverted and inserted into the printer's mounting bracket. The ink bottle connects to the printer's nozzles via an ink supply tube to supply ink to the nozzles.

[0003] In the existing technology, the connection between the cap and the bottle body of the existing ink bottle is mainly screw-on (threaded cap) and straight-insertion rubber stopper. Although these two methods provide convenience in daily use, they face considerable challenges during transportation. When the plastic ink bottle is shaken and squeezed, the ink can easily flow out along the gaps in the threads or rubber stopper, resulting in leakage. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the existing technology, ink bottles using screw-on (threaded cap) and straight-insertion rubber stopper sealing methods are prone to leakage during transportation when the plastic ink bottle is shaken and squeezed, causing the ink to flow out along the gaps in the threads or rubber stopper. Therefore, this invention proposes an ink bottle sealing structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an ink bottle sealing structure, comprising: a lower cover, an upper cover disposed at the top edge of the lower cover, a protrusion disposed near the center of the top of the lower cover, the protrusion being connected to the lower cover, and a sealing sheet disposed on the inner surface of the upper cover near the top.

[0006] Preferably, the top of the sealing sheet has multiple dotted lines at equal intervals near the center, and the inner surface of the top cover is in contact with the outer surface of the protrusion.

[0007] Preferably, a connector is provided at the top of the sealing sheet near the edge, and a pull ring is provided at the top of the connector.

[0008] Preferably, the outer surface of the upper cover is provided with a top cover, and the inner surface of the top cover is fitted to the outer surface of the upper cover.

[0009] Preferably, the outer surface of the top cover is symmetrically provided with locking blocks, and the inner surface of the top cover is symmetrically provided with locking slots, the locking slots and locking blocks being matched.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, during use, a sealing sheet is provided on the inner side of the upper cover. The upper cover, lower cover, and protrusion are integrally formed by ultrasonic welding to seal the mouth of the ink bottle. This changes the original screw-on (threaded cap) and direct-insertion rubber stopper sealing methods, avoiding gaps at the bottle mouth that could lead to leakage. The sealing effect is better. Furthermore, multiple dotted lines are made inside the upper cover, allowing personnel to press down and tear the sealing sheet along these lines for use. This solves the problem in the prior art where the screw-on (threaded cap) and direct-insertion rubber stopper sealing methods of ink bottles are prone to leakage during transportation when the plastic ink bottle is shaken and squeezed, causing ink to flow out along the gaps in the threads or rubber stopper.

[0012] 2. In this utility model, when in use, a top cover is provided on the outer surface of the upper cover. The top cover is fixed to the top of the upper cover by a slot on its inner side and a block provided on the outer surface of the upper cover. This plays a role in blocking and sealing, so that when there is a lot of ink left in the ink bottle, the top cover will seal the broken ink bottle and prevent dust and impurities from entering and affecting the quality of the ink. It is highly practical. Attached Figure Description

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1: As Figures 1-3 As shown, this utility model provides a sealing structure for an ink bottle, including: a lower cover 1, an upper cover 2 disposed at the top edge of the lower cover 1, a protrusion 6 disposed near the center of the top of the lower cover 1, the protrusion 6 being connected to the lower cover 1, a sealing sheet 10 disposed near the top of the inner surface of the upper cover 2, a plurality of dotted lines 11 being equidistantly opened near the center of the top of the sealing sheet 10, and the inner surface of the upper cover 2 being in contact with the outer surface of the protrusion 6.

[0020] The overall effect of Embodiment 1 is that when the ink bottle is sealed, the lower cover 1 is tightly fixed at the mouth of the ink bottle. After the ink is filled, the upper cover 2 is placed on top of the lower cover 1 and attached to the outer surface of the protrusion 6. The upper cover 2 is connected by ultrasonic welding. The inner surface of the upper cover 2 is integrally formed with a sealing sheet 10 near the top. After the lower cover 1 and the upper cover 2 are connected, they play a sealing role to prevent the ink in the ink bottle from leaking. When in use, the top of the sealing sheet 10 is pressed near the center. The sealing sheet 10 will deform under the action of external force, forcing its center to be concave. The sealing sheet 10 is torn along multiple pre-opened dotted lines 11, which plays a breaking role, making it convenient for personnel to add ink from the ink bottle to the printer.

[0021] Example 2: As Figures 1-3 As shown, a connector 7 is provided near the edge of the top of the sealing sheet 10, and a pull ring 8 is provided on the top of the connector 7. A top cover 3 is provided on the outer surface of the top cover 2. The inner surface of the top cover 3 is attached to the outer surface of the top cover 2. A locking block 4 is symmetrically provided on the outer surface of the top cover 2. A locking groove 5 is symmetrically opened on the inner surface of the top cover 3. The locking groove 5 and the locking block 4 are matched.

[0022] The overall effect of Embodiment 2 is that, during use, by setting a connector 7 at the top edge of the sealing sheet 10, and a pull ring 8 at the top of the connector 7, it is easy for personnel to pull the pull ring 8 to force the sealing sheet 10 to be torn off along the inner edge of the upper cover 2. This allows the ink bottle to have multiple ways of breaking when it breaks. By setting a top cover 3 on the outer surface of the upper cover 2, the top cover 3 is fixed to the top of the upper cover 2 by the cooperation of the slot 5 on its inner side and the locking block 4 on the outer surface of the upper cover 2. This plays a role in blocking and sealing, so that when there is a lot of ink left in the ink bottle, the top cover 3 will seal the broken ink bottle and prevent dust and impurities from entering and affecting the quality of the ink. It is highly practical.

[0023] Working principle: When the ink bottle is sealed, the lower cover 1 is tightly fixed at the mouth of the ink bottle. After the ink is filled, the upper cover 2 is placed on top of the lower cover 1 and attached to the outer surface of the protrusion 6. The two covers are connected by ultrasonic welding. A sealing sheet 10 is integrally formed on the inner surface of the upper cover 2 near the top. After the lower cover 1 and the upper cover 2 are connected, they play a sealing role to prevent ink leakage from the ink bottle. In use, pressing the top of the sealing sheet 10 near the center will deform the sealing sheet 10 under the action of external force, forcing its center to be concave. The sealing sheet 10 tears along multiple pre-cut dotted lines 11, thus breaking it open. To facilitate the refilling of ink bottles into printers, a connector 7 is provided at the top edge of the sealing sheet 10, with a pull ring 8 at its top. This allows personnel to pull the pull ring 8, forcing the sealing sheet 10 to tear along the inner edge of the upper cover 2. This provides multiple ways for the ink bottle to break. A top cover 3 is provided on the outer surface of the upper cover 2. The top cover 3 is fixed to the top of the upper cover 2 by a slot 5 on its inner side and a locking block 4 on the outer surface of the upper cover 2. This provides a sealing function, so that when there is a lot of ink left in the ink bottle, the top cover 3 will seal the broken ink bottle, preventing dust and impurities from entering and affecting the ink quality. This design is highly practical.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
