Description

Technical Field

[0001] This invention relates to the field of containers, and more particularly to a measuring cup with a lid. Background Technology

[0002] Plastic measuring cups with lids are widely used for measuring, storing, and transporting liquid and powder substances in applications such as chemical preparation, baking and cooking, and pharmaceutical dispensing.

[0003] Measuring cups currently on the market, especially large-capacity plastic measuring cups such as 5L plastic measuring cups, are in demand in many fields. However, the connection between the lid and the cup is relatively loose, making it easy for the liquid or other items inside the measuring cup to spill out or become contaminated by external objects. Furthermore, the guide rims used in commercially available measuring cups are uniformly high, but this guide structure prevents one-handed opening and closing after the lid is attached to one end of the measuring cup. The rim may also create localized interference and obstruction when opening and closing the lid, especially when the lid needs to be opened to more than 90 degrees. Inappropriate rim design can have a particularly noticeable impact on the opening and closing of the lid.

[0004] Therefore, developing a lidded measuring cup with a significant sealing effect that prevents leakage, can be opened and closed with one hand, and is not interfered with or obstructed by the cup rim during opening and closing, nor damaged by the rim, has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] To overcome the aforementioned technical deficiencies, the present invention aims to provide a measuring cup with a lid. This invention solves the problem of leak-proof sealing of the lid, allows for one-handed operation of the lid opening and closing, and ensures the lid remains in a designated position during the opening and closing process without interference, preventing accidental closure during use.

[0006] This invention discloses a measuring cup with a lid, comprising: a cup body, a lid that can be opened and closed connected to the cup body, and a handle disposed on the cup body. The cup body is also provided with graduation marks.

[0007] Also includes:

[0008] The snap-fit ​​structure includes a first snap-fit ​​member disposed on the edge of the cup lid and a second snap-fit ​​member disposed on the outer surface of the cup body, wherein the first snap-fit ​​member and the second snap-fit ​​member can be releasably engaged;

[0009] A lid-opening button is located on the lid and outside the edge of the lid near the handle.

[0010] The movable connection structure is connected at one end to the lid-opening button and at the other end to the handle, so as to be linked with the lid-opening button. Thus, the cup lid can be opened and closed as the lid-opening button moves and stay at any position between the first position of the cup lid and the second position of the maximum opening.

[0011] The inner edge of the cup lid is also provided with a guide edge: the guide edge extends along the inner surface edge of the cup lid with the two sides of the lid-opening button as the starting point, and the height of the guide edge gradually increases in the direction away from the lid-opening button; a groove is formed between the edge of the cup lid and the guide edge;

[0012] A sealing ring is disposed in the groove.

[0013] Optionally, the movable connection structure includes: a support shaft disposed on the handle, the free end of the support shaft being movably connected to the cover opening button.

[0014] Optionally, a support rod is provided at the free end of the support shaft, and a slot is provided inside the cover lifting button, wherein the support rod is rotatably engaged in the slot.

[0015] Optionally, the support rod is cylindrical, and the inner cavity of the slot is cylindrical.

[0016] Optionally, the active connection structure may also include: a resilient connector;

[0017] One end of the elastic connector is connected to one end of the handle, and the other end of the elastic connector is connected to the lid-opening button, so that the cup lid can be opened and closed with the lid-opening button as a fulcrum and can be positioned at any position between the first position and the second position from the cup body outlet plane upwards.

[0018] Optionally, the movable connection structure further includes: hooks disposed at one end of the handle and on the cover opening button, wherein both ends of the elastic connector are respectively fixed inside the hooks.

[0019] Optionally, the lid-opening button includes a pressing part; the height of the axis of the support shaft and the pressing part of the lid-opening button is higher than the height of the cup body outlet plane.

[0020] Optionally, the covered measuring cup further includes: a sealing cap edge disposed within the groove, extending along the outer side of the guide cap edge, and including an annular groove inside, the annular groove extending along the outer side of the guide cap edge; and a sealing ring disposed within the annular groove.

[0021] Optionally, the elastic connector is an elastic rubber ring.

[0022] Optionally, the elastic rubber ring is made of elastic plastic.

[0023] Optionally, the elastic connector is a spring.

[0024] Compared with existing technologies, the above technical solution has the following advantages:

[0025] 1. The cup lid and measuring cup are equipped with interlocking fasteners and suitable sealing rings, which ensure that the cup lid is firmly attached to the cup body without detachment or loosening, and prevents leakage and contamination of the contents.

[0026] 2. The cup lid is designed with a lid-opening button, which works in conjunction with the movable connecting structure to ensure that the cup lid opens, closes and rotates freely, and can be opened and closed with one hand; and during the opening and closing of the cup lid, the lid-opening button can be controlled by the thumb to keep the cup lid in a designated position.

[0027] 3. The cup lid and measuring cup handle are equipped with hooks with elastic connectors. By selecting elastic connectors of appropriate length and elasticity, the contraction performance of the elastic connectors helps to open the lid while preventing accidental closure during use.

[0028] 4. The inner side of the sealing ring groove on the inner side of the cup lid is designed with a partial lid edge that plays a positioning and guiding role, which overcomes the problem of traditional guide lid edges encountering obstacles during the opening and closing of the cup lid; the height of the guide lid edge near the lid opening button is reduced, which overcomes the interference and obstruction in the opening and closing process of the cup lid, and ensures that the cup lid can be opened and closed smoothly with one hand.

[0061] In the description of this invention, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0062] This invention provides a measuring cup with a lid, see reference. Figure 1 , Figure 1 A schematic diagram of a lidded measuring cup conforming to the present invention is shown. The lidded measuring cup includes: a cup body 1, a lid 2 that can be opened and closed connected to the cup body 1, and a handle 12 disposed on the cup body 1. The cup body 1 is also provided with graduation marks 11. The lidded measuring cup further includes: a snap-fit ​​structure (…). Figure 1 Not shown, see reference Figure 10 , 11 ), cover lifting button 21, movable connecting structure 3, guide cover edge 23 and sealing ring ( Figure 1 Not shown, see reference Figure 9 ).

[0063] The lid-opening button 21 is located on the cup lid 2 and is situated outside the edge of the cup lid 2 near the handle 12.

[0064] The movable connecting structure 3 has one end connected to the lid-opening button 21 and the other end connected to the handle 12, so as to be linked with the lid-opening button 21. This allows the cup lid 2 to open and close as the lid-opening button 21 moves, stopping at either a first position or a second position with the largest opening. The second position, where the lid 2 can be opened to its maximum extent, is configured by the measuring cup as needed. This invention, through the design of the interconnected lid-opening button 21, movable connecting structure 3, and cup lid 2, achieves stable support for the cup lid 2 and flexible one-handed opening and closing.

[0065] See Figure 4 , Figure 5 In a further embodiment of the present invention, the movable connection structure 3 specifically includes: a support shaft 31 disposed on the handle 12, the free end of the support shaft 31 being movably connected to the lid-opening button 21. In this embodiment, a support rod 311 is disposed at the free end of the support shaft 31, and a slot 211 is disposed on the inner side of the lid-opening button 21, the support rod 311 being rotatably engaged in the slot 211. Through the engagement of the lid-opening button 21 and the support rod 311, the user can control the lid-opening button 21 with the thumb of the hand holding the handle 12, achieving one-handed opening and closing of the cup lid 2. Specifically, the support rod 311 can be, for example, cylindrical, and the inner cavity of the slot 211 is cylindrical. The shape of the lid-opening button 21 can be varied, and the contact method with the support rod 311 on the handle 12 can also be varied; the present invention does not limit this. In this embodiment, the lid-opening button 21 is designed with an upward arc shape to ensure that the lid 2 can be opened and closed without much force.

[0066] In a preferred embodiment, the lid-opening button 21 includes a pressing part; the height of the axis of the support shaft 31 and the pressing part of the lid-opening button 21 is higher than the height of the outlet plane of the cup body 1. Even for a heavy measuring cup with a lid 2, it can be ensured that opening the lid 2 does not require much force and can be operated and controlled with one hand.

[0067] Figure 7 and Figure 8 The diagrams show the opening and closing of the cup lid 2 after the movable connection structure 3 conforming to the present invention is engaged with the lid-opening button 21. (See attached diagram.) Figure 7 and Figure 8The movable connection structure 3 further includes: an elastic connector 33; one end of the elastic connector 33 is connected to one end of the handle 12, and the other end of the elastic connector 33 is connected to the lid-opening button 21, so that by pressing the lid-opening button 21, the cup lid 2 can be opened and closed using the lid-opening button 21 as a fulcrum, and can stop at any position between the first position and the second position upward from the outlet plane of the cup body 1. Referring to 6, in this embodiment, the movable connection structure 3 further includes: a hook 32 disposed on one end of the handle 12 and the lid-opening button 21, and both ends of the elastic connector 33 are respectively fixed in the hook 32, and after installation, as Figure 7 or Figure 8 As shown, the hook 32 on the measuring cup handle 12, in addition to securing the elastic connector 33, also increases grip strength and stability when the thumb of the hand holding the handle 12 presses on the hook 32. This invention provides a hook 32 on both the measuring cup handle 12 and the lid-opening button 21. By selecting an elastic connector 33 of appropriate length and elasticity, and utilizing the contractile properties of the elastic connector 33, it provides assistance in opening the lid and resistance and cushioning against accidental closure, thereby preventing sudden lid closure.

[0068] In this embodiment, preferably, the elastic connector 33 is externally mounted to facilitate observation of its status and replacement. Specifically, the elastic connector 33 can be, for example, a flexible rubber ring made of plastic. The invention uses a flexible rubber ring on the measuring cup to prevent accidental closure because in the semiconductor chip industry, it is necessary to use fully elastic plastic components, and metal fittings cannot be used. For applications where metal fittings can be used, the elastic connector 33 can also be designed with a built-in flexible rubber ring or spring.

[0069] See Figures 1-3 Using the lidded measuring cup provided in the preceding paragraph of this invention, the lid 2 can be opened and closed, and can remain at any position between the closed state (facing upwards from the outlet plane of the cup body 1) and the maximum open state, with the lid release button 21 as the fulcrum. For example, by pressing the lid release button 21, the lid 2 can be opened from... Figure 3 As shown in the closed position, when the user presses the lid-opening button 21, the cup lid 2 opens as follows. Figure 1 The included angle α is approximately 45° at the opening and remains there until... Figure 2 The lid is opened at an angle α greater than 90° and then stopped, and opened to any position in between and then stopped, to avoid liquid overflow caused by sudden closing. The same effect is achieved when closing the lid in the opposite direction.

[0070] See Figure 9In this invention, the guide edge 23 extends along the inner surface edge of the cup lid 2, starting from both sides of the lid-opening button 21. The guide edge 23 gradually increases in height along its extension direction away from the lid-opening button 21, forming a design with unequal height guide edges 23. In this embodiment, the guide edge 23 at the lid-opening button 21 is at zero height, effectively eliminating the guide edge 23 structure near the lid-opening button 21 and removing any obstacles created by the guide structure. This unequal height local edge design retains the guiding function of the guide edge 23 while eliminating any potential obstruction when the guide edge 23 passes the cup rim during lid closing. This achieves rapid opening and closing of the plastic measuring cup lid 2 and protects the rim of the lid 2 and cup body 1 from accidental damage during lid closing. The specific height of the guide edge 23, including its possible rise and fall with the lid 2 and its termination position, can be determined according to various practical needs. To obtain better guiding effects, the gap between the guide edge 23 and the inner wall of the cup body 1 after lid closing can be made as small as possible.

[0071] A groove is formed between the edge of the cup lid 2 and the guide cover edge 23.

[0072] Optionally, the covered measuring cup further includes: a sealing cap edge 24, disposed within the groove, extending along the outer side of the guide cap edge 23, and including an annular groove 25 inside, the annular groove 25 extending along the outer side of the guide cap edge 23; the sealing ring is disposed within the annular groove 25 to achieve a sealing and leak-proof effect.

[0073] See Figures 10-11 The latching structure includes a first latching member 22 disposed on the edge of the cup lid 2 and a second latching member 13 disposed on the outer surface of the cup body 1. The first latching member 22 and the second latching member 13 can be releasably engaged. To achieve stable interlocking, the number of latches can be one or more pairs, such as... Figure 9 As shown. The shape of the buckle can vary. This invention provides a foldable and interlocking buckle structure on the cup lid 2 or measuring cup, which can effectively fix the cup lid 2. In this embodiment, the first buckle 22 is a foldable buckle. After installation, the first buckle 22 can be folded downwards to be parallel to the tangent direction of the cup body 1, making it convenient to carry and transport.

[0074] This invention, by attaching a sealing ring to the cup lid, allows the lid and cup body to interlock via a snap fastener, thus securing the lid tightly to the cup opening. Simultaneously, the sealing ring seals the edge between the lid and the cup opening, preventing the lid from shifting or loosening. This results in a good sealing effect, effectively preventing leakage and moisture.

[0075] In summary, by designing a snap-fit ​​structure, a lid-opening button, a movable connecting structure, a guide lid edge, and a sealing ring on the lidded measuring cup, this invention achieves the following effects: the lidded measuring cup is effectively sealed and leak-proof; the lid can be opened and closed with one hand; and the opening and closing position of the lid can be controlled and can stay in a specific position.

[0076] It should be noted that the embodiments of the present invention have better implementability and are not intended to limit the present invention in any way. Any person skilled in the art may use the above-disclosed technical content to change or modify it into equivalent effective embodiments. However, any modifications or equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
