Description

Technical Field

[0001] This utility model relates to the field of water cups, and in particular to a straw cup with a pressure relief function. Background Technology

[0002] The characteristic of a straw cup is that you drink liquids by inserting a straw. The lid has an opening, and the straw is inserted into the cup body through the opening. To keep the straw in place, there is usually a restraining part inside the opening to keep the straw in place and to prevent the straw from slipping out.

[0003] If the binding component and the straw fit together too tightly, it can easily obstruct airflow at the opening, making it difficult to quickly balance the air pressure inside and outside the cup, thus making it difficult to drink. If the binding component and the straw fit together with a gap, it is difficult to maintain a stable straw insertion position. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this invention is to provide a straw cup with a pressure relief function, which can maintain a stable insertion of the straw and quickly balance the air pressure inside and outside the cup.

[0005] The technical solution of this utility model is as follows: A straw cup with a pressure relief function includes a cup body and a cup lid that fits over the mouth of the cup body. The surface of the cup lid has a through-hole through which a straw is inserted into the cup body. A pressure relief plug is positioned inside the through-hole. The straw is adapted to pass through the pressure relief plug. The pressure relief plug has upper and lower expansion platforms around its periphery, forming an annular cavity between the expansion platforms. An air hole is provided through the upper expansion platform. The edge of the lower expansion platform has a groove. The groove and the air hole both pass through the annular cavity. The through-hole has a reduced diameter section. The upper and lower expansion platforms around the pressure relief plug abut against the upper and lower surfaces of the reduced diameter section.

[0006] Preferably, the top of the opening is threaded with a sealing cap, which covers the top section of the straw to achieve sealing protection of the straw, and at the same time blocks the air passage formed by the air hole, the annular cavity and the groove to prevent liquid from spilling.

[0007] Preferably, the upper surface of the cup lid has a groove, and the sealing cap is adapted to be inserted into the groove, which not only facilitates the placement of the sealing cap and prevents it from being lost, but also keeps the sealing cap clean by covering it with the groove.

[0008] Preferably, the bottom end of the straw is connected to a flexible tube, the connection length between the flexible tube and the straw is greater than the stacked height of the cup body and the cup lid, and the bottom edge of the flexible tube has a notch to prevent the bottom of the flexible tube from sticking to the bottom surface of the cup body, which would cause drinking difficulties.

[0009] Preferably, the air holes and grooves are evenly distributed in a ring, and the air holes and grooves are aligned vertically to expand the ventilation surface and ensure rapid and smooth balance of air pressure inside and outside the cup.

[0010] The beneficial effects of this utility model are as follows: 1. This utility model uses a pressure relief plug to restrain the straw, keeping the straw in a stable insertion state and preventing it from easily sliding. The air holes, annular cavity, and grooves around the pressure relief plug form an air passage connecting the inside and outside of the cup, which can quickly balance the air pressure inside and outside the cup, making it convenient to drink.

[0011] 2. This utility model places the pressure relief plug and the straw in one part. The straw and airway can be sealed simultaneously by the sealing cap. It is easy to operate and has a good sealing effect.

[0012] 3. This utility model has a groove on the surface of the cup lid for inserting and placing the sealing cap, which not only makes it convenient to place the sealing cap and avoid loss, but also keeps the sealing cap clean by covering it with the groove. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] A straw cup with pressure relief function, such as Figure 1 , Figure 2 As shown, it includes a cup body 1 and a cup lid 2. The cup lid 2 is threaded onto the mouth of the cup body 1. An opening 3 is provided on the surface of the cup lid 2, and a reduced diameter portion 31 is provided inside the opening 3. like Figure 3As shown, the main body of the pressure relief plug 4 is cylindrical. The inner diameter of the pressure relief plug 4 is adapted to the straw 5. The top and bottom of the outer periphery of the pressure relief plug 4 have two expansion platforms 41, and an annular cavity is formed between the two expansion platforms 41. An air hole 42 is opened through the upper expansion platform 41. The edge of the lower expansion platform 41 has a groove 43. The groove 43 and the air hole 42 are both connected to the annular cavity.

[0020] like Figure 4 As shown, the pressure relief plug 4 is placed inside the through-hole 3, and the upper and lower expansion platforms 41 abut against the upper and lower surfaces of the reduction section 31, so that the pressure relief plug 4 is positioned inside the through-hole 3. There is a gap between the annular cavity of the pressure relief plug 4 and the reduction section 31, so that the air hole 42, the annular cavity, and the groove 43 are connected vertically.

[0021] The straw 5 is inserted into the cup body 1 through the pressure relief plug 4. The pressure relief plug 4 keeps the straw 5 in a stable insertion state and prevents the straw 5 from sliding easily. When drinking liquid in the cup, the air inside and outside the cup body 1 is connected through the air hole 42, the ring cavity and the groove 43, which can quickly balance the air pressure inside and outside the cup and make drinking convenient.

[0022] like Figure 3 As shown, there are multiple air holes 42 and grooves 43 evenly distributed in a ring. The air holes 42 and grooves 43 are aligned vertically to expand the ventilation surface and ensure rapid and smooth air pressure balance inside and outside the cup body 1.

[0023] like Figure 1 , Figure 2 As shown, the inlet 3 has an internal thread, and the sealing cap 6 has an external thread. When not in use, the sealing cap 6 is threadedly connected to the top of the inlet 3, covering the top section of the straw 5, thus sealing and protecting the straw 5. At the same time, it also blocks the air passage formed by the air hole 42, the annular cavity, and the groove 43, preventing liquid from spilling.

[0024] If the cup contains a hot liquid, during the process of opening the sealing cap 6 and separating it from the top of the straw 5, the air passage is opened first to release the air pressure inside the cup, and the sealing cap 6 covers the straw 5 to prevent liquid from splashing.

[0025] like Figure 1 , Figure 2 As shown, a groove 7 is provided on the upper surface of the cup lid 2. The groove 7 is adapted to the diameter of the sealing lid 6. When drinking liquid through the straw 5 after opening the sealing lid 6, the sealing lid 6 is inserted into the groove 7. This not only makes it convenient to place the sealing lid 6 and avoids loss, but also keeps the sealing lid 6 clean by covering it with the groove 7.

[0026] like Figure 1 , Figure 2As shown, a flexible tube 51 is fitted onto the bottom end of the straw 5. The connection length between the flexible tube 51 and the straw 5 is greater than the stacked height of the cup body 1 and the cup lid 2. The flexible tube 51 supports the straw 5 so that it protrudes from the opening 3, which not only makes it easy to drink, but also ensures that the flexible tube 51 can touch the bottom to ensure that all the liquid in the cup body 1 can be drunk. When the sealing cap 6 is used to seal the opening 3, the sealing cap 6 presses down on the straw 5, and the flexible tube 51 deforms to make the straw 5 retract accordingly, making it easy for the sealing cap 6 to close.

[0027] The bottom edge of the hose 51 has a notch 52 to prevent the bottom of the hose 51 from sticking to the bottom surface of the cup body 1, which would cause poor drinking.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
