Detailed Description
The technical scheme of the utility model is described below with reference to the accompanying drawings and examples.
As shown in fig. 1-2, the rolled straw according to the present utility model includes a body 1, wherein one side edge of the body 1 is a first cutting edge 11, the other side edge of the body 1 is a second cutting edge 12, the body 1 is rolled into a tubular shape, and in fig. 1, in a natural state, an inner side wall of the body 1 at the first cutting edge 11 is located at an outer side wall of the body 1 at the second cutting edge 12; in fig. 2, in the sealed state, the inner side wall of the body 1 at the second cut-off edge 12 is wrapped around the outer side wall of the body 1 at the first cut-off edge 11, so that a flow passage 13 penetrating both ends of the body 1 is formed inside the body 1.
As shown in fig. 2, when the body 1 is curled in a tubular shape, the curvature of the bonding portion of the first cutting edge 11 is RAD1, and the curvature of the bonding portion of the second cutting edge 12 is RAD2, then RAD1 is equal to or less than RAD2. The joint portion of the first cutting edge 11 and the joint portion of the second cutting edge 12 have a curvature difference, and in a natural state (in fig. 1, the suction pipe is in a mold-out state), the first cutting edge 11 can be lapped on the outer side wall of the body 1 from which the second cutting edge 12 is formed to be covered, and when an outward pressure is generated in the flow channel 13 inside the suction pipe or an inward pressure is generated from the outer wall of the suction pipe, a gap is generated on the covered surface between the first cutting edge 11 and the second cutting edge 12, so that the tightness of the flow channel 13 is damaged.
In the sealed state (fig. 2 is a straw use state), the second cutting edge 12 is lapped on the outer wall of the body 1 at the first cutting edge, the bending part of the body 1 at the second cutting edge 12 is attached to the outer wall of the bending part of the body 1 at the first cutting edge 11, and the bending part at the second cutting edge 12 can generate larger pressure to attach to the bending part at the first cutting edge 11.
The body 1 is in the strip shape when being unfolded, the unfolding length of the body 1 corresponds to the length of the suction pipe, the unfolding width of the body 1 is larger than the perimeter of the suction pipe, a tubular structure is formed after the body 1 is curled, the first cutting edge 11 and the second cutting edge of the body 1 are mutually closed, and the inner hole of the body forms a flow channel 13 so as to realize the function of the suction pipe. It will be appreciated that the closure of the first and second cut-off edges 11, 12 serves to seal the wall of the straw, and in practice the first and second cut-off edges 11, 12 may be staggered with respect to each other so that the curled body 1 partially overlaps to improve the sealing of the straw. The body 1 after use can be unfolded for cleaning so as to be convenient for repeated use.
The width between the first cutting edge 11 and the second cutting edge 12 is L, and the perimeter of the body 1 when curled into a tubular shape is S, L > S (not shown in the drawings). When the suction pipe is subjected to inward and outward pressure, the bonding width L between the second cutting edge 12 and the first cutting edge 11 is gradually reduced, and the bonding force between the second cutting edge 12 and the first cutting edge 11 is increased due to the reduction of the bonding width L, so that the sealing performance of the suction pipe is improved.
It will be appreciated that the change in the engagement width L of the engagement surface is a surface-to-line process and that this process is proportional to the pressure to which the straw is subjected. When the suction pipe is at the critical pressure value, only the second cutting edge 12 is in contact with the outer wall of the body 1 at the first cutting edge 11, and the critical pressure value of the suction pipe in the sealed state is larger than that in the natural state.
The thickness of the body 1 near the first cutting edge 11 is H1, and the thickness H2 of the body 1 near the second cutting edge 12 is H1 less than or equal to H2. The thickness of the body 1 near the first cutting edge 11 is H1, and the thickness H2 of the body 1 near the second cutting edge 12 is H1 less than or equal to H2. When the body 1 is curled, the first cutting edges 11 and the second cutting edges 12 on two sides of the body 1 are staggered, the side walls of the body 1 are partially overlapped, because the body 1 has curling stress, the first cutting edge 11 on the outer side has smaller curvature RAD1, the second cutting edge 12 on the inner side has larger curvature RAD2, the body 1 between the first cutting edge 11 and the second cutting edge 12 is overlapped with each other, at least two contact lines are formed, one contact line is formed by the first cutting edge 11 abutting against the (inner/outer) side wall of the body 1, the other contact line is formed by the second cutting edge 12 abutting against the (inner/outer) side wall of the body 1, and the inner side wall and the outer side wall of the body 1 are in cohesion so as to enable the flow channel 13 to form a seal.
The body 1 comprises a first semicircular tube 2 and a second semicircular tube 3, wherein the first side edge of the first semicircular tube 2 is fixedly connected with the first side edge of the second semicircular tube 3; the second side edge of the first semicircular tube 2 correspondingly forms a first cutting edge 11, and the second side edge of the second semicircular tube 3 correspondingly forms a second cutting edge 12; when the body 1 is curled, the radius of the first semicircular tube 2 is R1, the radius of the second semicircular tube 3 is R2, and part of the inner side wall of the first semicircular tube 2 is wrapped on part of the outer side wall of the second semicircular tube 3. The first semicircular tube 2 and the second semicircular tube 3 are only used as an example of the form of the forming mold of the body 1, and of course, the body 1 can also be formed by using a spiral mold, so that the body 1 is naturally curled, and because the radii of the first semicircular tube 2 and the second semicircular tube 3 are different, a holding force can be formed when the body 1 is curled, that is, the inner side wall of the body 1 at the first cutting edge 11 holds the outer side wall at the second cutting edge 12, so that the tightness of the flow channel 13 is ensured.
The body 1 is made of elastic material, the body 1 has elastic stress to make the body 1 curled in natural state, and the body 1 can be unfolded under the action of external force to clean the internal flow channel 13. The expandable body 1 is provided with an inner side wall which is easier to clean, and the flow channel 13 is correspondingly formed on the inner side wall of the body 1.
As shown in fig. 3, the utility model further comprises a fixing piece 4, wherein the fixing piece 4 is of a hollow structure with two through ends, one end of the fixing piece 4 can be connected with any one end of the curled body 1 in a pairing manner, and the other end of the fixing piece 4 is provided with a sharp head. The shape of the fixing member 4 may be any shape, that is, one end caliber of the fixing member 4 matches the outer diameter of the curled body 1, or the fixing member 4 has an inner ring and an outer ring to match the end of the body 1, so as to avoid the curled state of the body 1 from being damaged, and of course, the sharp head at the other end of the fixing member 4 may pierce the sealing film of the beverage cup for convenient use.
The foregoing description is only of the preferred embodiments of the utility model, and all changes and modifications that come within the meaning and range of equivalency of the structures, features and principles of the utility model are therefore intended to be embraced therein.
