Description

Technical Field

[0001] This utility model relates to spray products, specifically to a rotating spray cap for a spray can. Background Technology

[0002] Spray cans are widely used in cosmetics, fragrances, insecticides, and other applications, dispensing their contents by pressing a screw cap. However, during transport and storage, accidental pressing of the cap can cause the valve to open unexpectedly, resulting in waste and contamination. Since most existing cap designs have the pressing part molded directly into the cap body, pressing relies on the plastic's deformation properties to move the pressing part downwards, triggering the valve to open. Therefore, adjusting the deformation properties based on the plastic's characteristics could reduce the risk of accidental pressing to some extent, requiring more external force. However, this approach not only fails to truly eliminate the problem of accidental pressing but also makes pressing more difficult for users, resulting in a poor user experience. Utility Model Content

[0003] This utility model proposes a rotating spray cap for a spray can, aiming to improve the pressing feel of the cap and prevent accidental pressing. This is achieved through the following technical means:

[0004] A rotating spray cap for a spray can includes a connecting seat for connecting to the spray can and a cap movably disposed on the connecting seat. A pressing member is provided on the cap. The pressing member has a spray nozzle on its side, an insertion channel at its bottom, and a jet channel connecting the spray nozzle and the insertion channel. The cap extends vertically and is recessed downwards along its upper edge to form a first groove. The pressing member is housed within the cap, and the side of the pressing member with the spray nozzle is connected to the bottom of the first groove, thereby creating a gap between this side and the groove wall. A limiting body is provided on the connecting seat, and a pressing body is provided at the bottom of the pressing member. When the pressing body rotates to be opposite the limiting body, the downward movement of the pressing member is restricted; when the pressing body rotates to be offset from the limiting body, the restriction on the pressing member is released.

[0005] In one or more embodiments of the present invention, the connecting seat is provided with a connecting ring platform for engaging with the screw cap, a first retaining edge is provided on the outer side of the connecting ring platform, a second retaining edge is provided on the inner side of the screw cap to engage with the first retaining edge, and the limiting body is provided on the connecting ring platform.

[0006] In one or more embodiments of the present invention, the connecting ring platform is provided with an annular groove with the opening facing upward, and a plurality of baffles are provided at intervals in the annular groove. The cap is provided with a limiting post extending into the annular groove, and the limiting post moves in the annular groove as the cap rotates.

[0007] In one or more embodiments of this utility model, the spray nozzle is provided with a central column and a mist dot sleeved on the central column. The mist dot is provided with a sleeve groove, and a plurality of sleeve protrusions are provided on the groove wall. When the mist dot is sleeved with the central column, an air mist channel is formed between each sleeve protrusion, which connects to the bottom of the sleeve groove. A plurality of collecting grooves converging towards the center are provided at the bottom of the sleeve groove, and a spray hole connecting to the outside of the mist dot is provided in the middle of the bottom of the groove. The diameter of the spray hole decreases from the inside to the outside.

[0008] In one or more embodiments of the present invention, the outer wall of the mist dot is provided with a third retaining edge for abutting against the inner wall of the spray nozzle.

[0009] In one or more embodiments of the present invention, the lower end opening of the plug channel is outwardly flared, one side of the upper end of the plug channel is connected to the jet channel, and its upper end face is inclined to provide a force that compresses the contents into the jet channel when the contents flow through it.

[0010] In one or more embodiments of the present invention, a second groove is provided on the other side of the cap opposite to the first groove, and the bottom of the second groove is lower than the pressing surface of the pressing member.

[0011] In one or more embodiments of this utility model, the pressing surface is recessed and provided with anti-slip protrusions.

[0012] Compared with the prior art, the advantages of this utility model include at least the following:

[0013] 1) The cap and the pressing part are integrally injection molded and a first groove is set at the connection position between the two, so that a gap is formed between the side and the groove wall of the first groove. This gap structure increases the deformation space of the pressing part. Unlike the traditional structure where the pressing part deforms together with the cap, the pressing force is smaller, the pressing feel is better, and the pressing durability is also improved.

[0014] 2) The limiting body of the connecting seat cooperates with the top pressing body on the pressing part to lock and unlock the pressing stroke of the pressing part; as the cap rotates, when the top pressing body rotates to be directly above the limiting body, the limiting body stops the top pressing body from moving downward, so that the pressing part is in the locked state; when the top pressing body rotates to be opposite to the limiting body, the pressing part is in the unlocked state because it is no longer blocked by the limiting body, and only a light pressure is needed to make the pressing part move downward, thereby triggering the valve to open.

[0015] 3) The sleeve groove wall of the mist dot is provided with several sleeve protrusions. When the mist dot is sleeved with the central column, an aerosol channel is formed between each sleeve protrusion, which connects to the bottom of the sleeve groove. There are several gathering grooves at the bottom of the sleeve groove that converge towards the center. These gathering grooves are connected to the spray hole in the middle of the bottom of the groove. The diameter of the spray hole decreases from the inside to the outside, which makes the contents liquid have better atomization and spraying effect. Attached Figure Description

[0025] The following is in conjunction with the appendix Figures 1 to 9 The following is a further description of the proposed solution:

[0026] The rotating spray cap of this utility model includes a connecting base 1 for connecting to the spray can and a cap 2 movably disposed on the connecting base. A pressing member 3 is provided on the cap 2. The pressing member 3 is provided with a spray nozzle 31 located on its side, an insertion channel 32 located at its bottom, and a spray channel 33 connecting the spray nozzle 31 and the insertion channel 32. The cap 2 is vertically continuous and a first groove 201 is formed by the downward recess of its upper edge. The pressing member 3 is housed in the cap 2, and the side of the pressing member 3 with the spray nozzle 31 is connected to the bottom of the first groove 201, thereby forming a gap 201a between this side and the groove wall of the first groove 201.

[0027] The connecting seat 1 is provided with a limiting body 11, and the bottom of the pressing member 3 is provided with a top pressing body 34. As the cap rotates, when the top pressing body 34 rotates to be opposite the upper part of the limiting body 11, the limiting body 11 blocks the downward movement of the top pressing body 34, thus restricting the downward movement of the pressing member 3 and keeping the pressing member 3 in a locked state, preventing accidental release of the valve of the spray can due to accidental pressing. When the top pressing body 34 rotates to be opposite the limiting body 11, the pressing member 3 is unlocked due to the removal of the obstruction of the limiting body 11. Only a light pressure is needed to make the pressing member 3 move downward, thereby triggering the valve to open.

[0028] This product integrally injection molds the cap 2 and the pressing component 3 and sets a first groove 201 at the connection position between the two, thereby forming a gap 201a between this side and the groove wall of the first groove 201. This gap 201a structure increases the deformation space of the pressing component 3. Unlike the traditional structure in which the pressing component 3 deforms together with the cap 2, this product requires less pressing force, has a better pressing feel, and also improves the pressing durability. This is because the pressing component 3 has a locked state through the above structure, which makes it possible to make optimized designs to improve the pressing feel.

[0029] Furthermore, the connecting seat 1 is provided with a connecting ring platform 12 for engaging with the cap 2. An outwardly turned first retaining edge 13 is provided on the outer side of the connecting ring platform 12. The limiting body 11 is also provided on the connecting ring platform 12. The inner side of the cap 2 is provided with a second retaining edge 21 that engages with the first retaining edge 13. With the engagement of the first retaining edge 13 and the second retaining edge 21, not only can the connecting seat 1 and the cap 2 engage with each other, but the cap 2 can also rotate under the limiting action of the first retaining edge 13. The connecting ring platform 12 is provided with an upward-facing annular groove 14. Several baffles 15 are spaced apart within the annular groove 14. The cap 2 is provided with a limiting post 22 extending into the annular groove 14. The limiting post 22 moves within the annular groove 14 as the cap 2 rotates. When it moves to contact the baffle 15, it is restricted from further movement by the baffle 15, thereby limiting the rotation angle of the cap 2.

[0030] Furthermore, the spray nozzle 31 is provided with a central column 311 and a mist point 4 sleeved on the central column 311. The mist point 4 is provided with a sleeve groove 41. Several sleeve protrusions 42 are provided on the groove wall of the sleeve groove 41. When the mist point 4 is sleeved with the central column 311, an aerosol channel 41a is formed between each sleeve protrusion 42, which connects to the bottom of the sleeve groove 41. The spray channel 33 is connected to the side of the central column 311, so that the liquid contents flow from the side of the central column 311 into each aerosol channel 41a. Several collecting grooves 41b are provided at the bottom of the sleeve groove 41, which converge towards the center. A spray hole 43 is provided in the middle of the bottom of the groove, which connects to the outside of the mist point 4. The diameter of the spray hole 43 decreases from the inside to the outside, which makes the liquid contents have better atomization and spraying effect. The outer wall of the mist dot 4 is provided with a third retaining edge 44 for abutting against the inner wall of the spray nozzle 31. The third retaining edge 44 is used to abut against the inner wall after the mist dot 44 is pressed into the spray nozzle 31, thereby preventing the mist dot 4 from falling out of the spray nozzle 31 due to pressure.

[0031] Furthermore, the lower opening of the plug channel 32 is outwardly flared and gradually narrows upward, thus accommodating more valve stem specifications. The upper side of the plug channel 32 is connected to the jet channel 33, and its upper end face 32a is inclined to provide a force that compresses the contents into the jet channel 33 when the contents flow through it.

[0032] Furthermore, to facilitate pressing the pressing member 3, a second groove 202 is provided on the other side of the cap 2 opposite to the first groove 201. The bottom of the second groove 202 is lower than the pressing surface 30 of the pressing member 3, so that the pressing member 3 can be easily pressed down without being blocked by the cap 2 when pressed with a finger. To improve the pressing feel, the pressing surface 30 is recessed and has anti-slip protrusions 301.

[0033] The above preferred embodiments should be regarded as illustrative examples of the embodiments of the present application. Any technical deductions, substitutions, improvements, etc. that are similar to or based on the present application should be considered within the scope of protection of this patent.
