Description

Technical Field:

[0001] The present invention belongs to the field of daily necessities, and particularly relates to a straw cup, especially a solution using a self-elastic straw. Background Art:

[0002] There are various structures of existing self-elastic straw cups, but some of the straws used are too soft, affecting the sucking experience. For example, patent application number 201811536594.2 discloses a straw cup that prevents water from spraying when the lid is opened, including a first-level cup lid with a soft straw, a second-level cup lid, a cup body, and a push rod inserted into the top cover surface of the first-level cup lid; there is a vertically penetrating air vent passage on the first-level cup lid, and a horizontal empty groove is provided in the top cover surface, which penetrates from the side of the first-level cup lid surface to the straw position and is divided into two parts through the air vent passage; the push rod is inserted into the empty groove; there is a butt joint air vent on the push rod, which is butt jointed with the air vent passage; when the second-level cup lid is closed, the push rod is in the initial position, and the butt joint air vent is staggered and sealed with the air vent passage; when the push rod is pushed, the butt joint air vent is docked with the air vent passage to discharge air, and the push rod squeezes the straw into a closed state. This technology has a good design concept, but it is obviously difficult to achieve airtightness by relying on the sliding of the push rod to close or open the air vent passage. Especially when containing hot water at a relatively high temperature, there may be a water leakage phenomenon; furthermore, the straw is squeezed by the second-level cup lid in the recess reserved on the first-level cup lid, and a softer straw needs to be configured.

[0003] How to improve the deficiencies of the existing technology has become the object of research of the present invention. Summary of the Invention:

[0004] The object of the present invention is to design a straw cup in which the straw is swung by a protective cover and is squeezed and bent by a following optical rod to form a closed state; the secondary object is to form a sealed structure by pressing the bent section of the straw against the return air vent.

[0005] The technical solution of the present invention is realized as follows: A straw cup includes a cup body, an outer cover, an inner cover with a soft and elastic straw, and a push rod; it is characterized in that: a protective cover is provided on the upper section of the straw above the inner cover, and the smooth rod on the protective cover supports below the straw to form a clamping state; the protective cover is positioned on the flip cover through a first shaft, and the flip cover is positioned on the outer cover through a second shaft, and the trailing edge of the flip cover overlaps on the leading edge of the protective cover. When the straw pops up, it can push open the protective cover and the flip cover in sequence; when the flip cover is closed, it can drive the protective cover to close to the top surface of the outer cover, and the smooth rod that swings backward forces the straw to bend and close; the front end of the push rod has a button, the middle section has an inclined tongue block, and the rear end has a guiding rod, which is slidably arranged between the inner cover and the outer cover, and the button penetrates through the keyhole reserved on the outer cover. A return spring is sleeved on the guiding rod, and one end of the return spring abuts against the outer cover, always keeping the tendency of the button protruding from the surface of the keyhole; the two sides of the flip cover have inclined hook feet, and the downward inclined hook feet can drive the inclined tongue block to move backward and be locked by the rebounding inclined tongue block.

[0006] A return air hole also protrudes upward at the central position of the inner cover, and the return air hole extends out of the long slot hole reserved by the push rod and can be pressed and sealed by the bent straw.

[0007] The straw has a sucking section, a bending section, an embedding ring and an immersion section from top to bottom, and a circular step surface is formed at the junction of the sucking section and the bending section; the front end of the protective cover has a clamping mouth, a smooth rod and a limiting convex point are arranged at the rear end, and the clamping mouth is used to clamp on the circular step surface, and the limiting convex point can be blocked by the convex part on the inner cover or the outer cover after being opened to form a constraint on the opening angle.

[0008] The first shaft for positioning the protective cover on the flip cover and the second shaft for positioning the flip cover on the outer cover are not on the same axis, and the first shaft is above the second shaft in the closed state of the flip cover.

[0009] Shaft arms are integrally connected to the flip cover behind the inclined hook feet on both sides, and shaft protrusions are formed on both sides of the shaft arms to correspondingly form the first shaft and the second shaft; correspondingly formed shaft holes for inserting and positioning the first shaft and the second shaft are provided on the protective cover and the outer cover.

[0010] An arc-shaped lock piece is provided on the inner cover corresponding to the stroke of the push rod button to restrict the movement of the button; the arc-shaped lock piece is movably fitted on the arc-shaped groove formed on the skirt of the inner cover, and a gear for correspondingly restricting the forward and stop positions of the button is provided between the arc-shaped groove and the arc-shaped lock piece; an operation handle protrudes from the surface of the arc-shaped lock piece, and the operation handle protrudes from the groove reserved on the skirt of the outer cover.

[0011] A rounded convex point protrudes from the edge of the arc-shaped groove of the inner cover, and rounded concave notches are formed at the corresponding forward and stop positions on the edge of the arc-shaped lock piece. The rounded concave notches and the rounded convex points cooperate to form the forward and stop gears.

[0012] The middle section of the push rod is a sheet-like structure. Outside the inclined tongue blocks on both sides, a straight groove is formed on each side. On the inner side of the outer cover, a pair of downward convex rails are formed. The convex rails run through the entire interior of the outer cover, functioning as connecting ribs. When assembled in place, the convex rails are inserted into the straight grooves of the push rod, restricting the push rod to only slide linearly back and forth.

[0013] A handle is also configured on the outer cover. On both sides of the handle, expansion shaft protrusions and positioning convex points are integrally formed inward. On the top surface of the outer cover, a convex edge protruding upward is formed around the protective cover and the flip cover. By means of this convex edge, a shaft hole for positioning the flip cover is provided, and on the outside of the convex edge, a shaft hole and a positioning concave hole for inserting the handle are symmetrically formed. The handle is inserted into the shaft hole through the expansion shaft protrusion to form a positioning structure.

[0014] The present invention has the characteristics of ingenious design, reasonable design, good airtightness, and many associated actions. In particular, by utilizing the cooperation between the protective cover and the straw, during the covering process, the straw can be forced to bend, simultaneously closing the return air hole, and the straw can also be stretched. During the opening process, the stretched straw can quickly retract, and the protective cover and the flip cover can be bounced open together. The protective cover is maintained and stabilized at the designed angle under the dual action of the limit convex point and the straw, ensuring drinking comfort. And the flip cover can continue to flip to avoid blocking the mouth and nose. BRIEF DESCRIPTION OF THE DRAWINGS:

[0034] Refer to Figures 1 to 6 , a straw cup, including a cup body 1, an outer cover 2, an inner cover 3, a straw 4, a push rod 5, a protective cover 6 and a flip cover 7, wherein the straw 4 is formed of a soft and elastic material. The inner cover 3 is thread - fitted and locked on the cup body 1, and is provided with necessary sealing rings, etc., which is a conventional technology.

[0035] The straw 4 has a sucking section 41, a bending section 42, an insertion ring 43 and an immersion section 44 from top to bottom. That is, the immersion section 44 can penetrate into the cup body 1 and be immersed under the liquid surface. Of course, it also includes a pipe fitting at the lower end that can penetrate into the bottom of the cup; an annular step surface 45 is formed at the intersection of the sucking section 41 and the bending section 42; a protective cover 6 is arranged on the bending section 42 of the straw 4, that is, it is clamped on the outer side of the bending section 42 and can swing to bend the straw 4.

[0036] The front end of the protective cover 6 has a clamping opening 61, the rear end is provided with a smooth rod 62 and a limit bump 63. The clamping opening 61 is used to clamp on the annular step surface 45 of the straw, and the smooth rod 62 supports under the bending section 42 of the straw, and together with the clamping opening 61, forms a clamping effect on the straw 4; the limit bump 63 can be blocked by the protrusion 31 on the inner cover 3 or the outer cover 2 after being opened, forming a constraint on the opening angle. According to the drinking habit, the elevation angle of the straw 4 is generally between 60 degrees and 80 degrees. The above - mentioned smooth rod 62 is a separated shaft rod and is second - assembled on the protective cover 6.

[0037] The protective cover 6 is positioned on the flip cover 7 through the first shaft 71. The flip cover 7 is in turn positioned on the outer cover 2 through the second shaft 72. The trailing edge of the flip cover 7 overlaps the leading edge of the protective cover 6. When the straw 4 pops up, it can push open the protective cover 6 and the flip cover 7 in sequence. When the flip cover 7 closes, it can drive the protective cover 6 to approach the top surface of the outer cover 2, and the straw 4 is forced to bend and close by means of the light rod 62 that swings backward.

[0038] Furthermore, the first shaft 71 on which the protective cover 6 is positioned on the flip cover 7 and the second shaft 72 on which the flip cover 7 is positioned on the outer cover 2 are not on the same axis. In the closed state of the flip cover 7, the first shaft 71 is above the second shaft 72. That is to say, the first shaft 71 is an offset eccentric shaft and can swing along with the flip cover 7. During the closing process of the flip cover 7, the first shaft 71 swings around the second shaft 72 through an arc, that is, it drives the protective cover 6 to perform an arc swing. At this time, a stretching action can be formed on the bent section 42 of the straw, causing the straw 4 to undergo stretching deformation and be in a state of storing energy. When the flip cover 7 is opened instantly, the stretching deformation force can be used to bounce open the protective cover 6 and the flip cover 7 together, and the open state is maintained according to the elasticity of the straw 4 material. In addition, the eccentric position of the first shaft 71 can also be used to always maintain an angle between the flip cover 7 and the sucking section 41 of the protective cover 6 and the straw in the open state, avoiding interfering with the lip sucking action. This is also one of the design features.

[0039] On both sides of the flip cover 7, there are downward inclined hook feet 73, and there are shaft arms 74 connected to the rear. Shaft protrusions are formed on both sides of the shaft arms 74 to correspondingly form the first shaft 71 and the second shaft 72. Corresponding shaft holes 21 for inserting and positioning the first shaft 71 and the second shaft 72 are formed on the protective cover 6 and the outer cover 2. During assembly, with the help of the deformation of the outer cover and the protective cover materials, the convex shafts can be inserted.

[0040] The front end of the push rod 5 has a button 51, the middle section is a sheet-like structure with inclined tongue blocks 52 on both sides, and the rear end has a guiding rod 53. A straight groove 54 is formed on the outside of each inclined tongue block 52. The push rod 5 is slidably arranged between the inner cover 3 and the outer cover 2 and is slidably restricted by a pair of downward convex rails 23 of the outer cover 2. The button 51 passes through the keyhole 22 reserved on the outer cover 2. A return spring 55 is sleeved on the guiding rod 53. One end of the return spring 55 abuts against the outer cover 2, always maintaining the tendency for the button 51 to protrude from the surface of the keyhole 22, which is convenient for finger pressing to start.

[0041] During the closing process of the flip cover 7, the downward inclined hook feet 73 on both sides of it can drive the inclined tongue blocks 52 on the push rod to move backward and be locked by the rebounded inclined tongue blocks 52, forming the closing positioning of the flip cover 7. At the same time, the protective cover 6 is also positioned, and the bent section 42 of the straw is kept in the bent and closed state.

[0042] On the inner side of the outer cover 2 corresponding to the straight groove 54 on the push rod, a pair of downward convex rails 23 are formed. The convex rails 23 penetrate through the entire interior of the outer cover and function as connecting ribs. When assembled in place, the convex rails 23 are embedded in the straight groove 54 of the push rod, restricting the push rod 5 to only perform linear reciprocating sliding. The outer cover 2 is snap-fitted and positioned on the inner cover 3 through a ring-shaped discount, and tenon grooves for preventing relative rotation are also provided on the mating surfaces of the two.

[0043] Furthermore, a return air hole 32 protrudes upward at the central position of the inner cover 3. The return air hole 32 extends out of the long slot hole 56 reserved for the push rod 5 and can be pressed and sealed by the bent straw 4. The return air hole 32 is closed by means of the bent section 42 to avoid dripping. Moreover, when the straw 4 rebounds, it also preferentially opens the return air hole 32, quickly balancing the air pressure inside and outside the cup body 1, achieving two goals with one action.

[0044] Furthermore, on the stroke of the push rod button 51 corresponding to the inner cover 3, an arc-shaped lock piece 8 is provided to restrict the movement of the button 51 by using the arc-shaped lock piece 8; the arc-shaped lock piece 8 is movably fitted on the arc-shaped groove 33 formed on the skirt of the inner cover 3. A gear position for correspondingly restricting the movement and stop positions of the button 51 is provided between the arc-shaped groove 33 and the arc-shaped lock piece 8, that is, corresponding to the open and locked states of the flip cover 7; an operation handle 81 protrudes from the surface of the arc-shaped lock piece 8, and the operation handle 81 protrudes out of the slot 24 reserved on the skirt of the outer cover 2. It can also be said that the strokes at both ends of the slot 24 correspond to the open and locked states, and effective positioning is formed by means of the gear position to avoid free sliding. The gear position refers to: a rounded convex point 34 protrudes from the edge of the arc-shaped groove 33 of the inner cover, and a rounded concave notch 82 corresponding to the movement and stop positions is formed on the edge of the arc-shaped lock piece 8. The rounded concave notch 82 and the rounded convex point 34 cooperate to form the movement and stop gear positions. By using the arc-shaped lock piece 8 to occupy or release the space for the button 51 to retreat, two gears of movement and stop can be switched.

[0045] Furthermore, a handle 9 is also configured on the outer cover 2. The handle 9 has a U-shaped structure, and expansion shaft protrusions 91 and positioning convex points 92 are integrally formed inward on both sides; a convex edge 25 protruding upward is formed on the top surface of the outer cover 2 around the protective cover 6 and the flip cover 7. By means of the convex edge 25, a shaft hole 21 for flip cover positioning is provided, and a shaft hole 21 for inserting the handle 9 and a positioning concave hole 26 are symmetrically formed on the outside of the convex edge 25. The handle is inserted into the shaft hole 21 on the outside of the convex edge by means of the expansion shaft protrusion 91 to form a positioning structure. When the handle 9 is not in use or during drinking, it can be fitted outside the convex edge of the outer cover 2. At this time, the positioning convex point 92 on the handle just cuts into the positioning concave hole 26 on the outside of the convex edge, forming a reliable positioning relationship and coinciding with the convex edge 25, and the appearance is not obtrusive.
