Description

Technical Field

[0001] The utility model relates to the technical field of packaging containers, in particular to a sinking-type cover-opening pump. Background Art

[0002] The push pump is mostly used for bottled shampoo and other similar liquid filling daily necessities. In order to avoid accidentally touching the push pump to squeeze out the solution in the bottle and cause waste, a locking design is required for the push pump. The existing method of locking the push pump is to press the push pump downward and rotate it so that the movable part of the push pump is threadedly connected with the fixed part, thereby locking the push pump;

[0003] However, this method has complicated operation steps, requiring pressing and rotating, and cannot be operated with one hand, making it inconvenient to take items equipped with such a press pump. Utility Model Content

[0004] The purpose of the utility model is to provide a pump with a sunken opening cover in order to solve the above-mentioned problems, as described below.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The utility model provides a sinking-type open-cover pump, comprising a pressing pump and a bottle body, wherein the pressing pump is mounted on the bottle body, and an upper cover is arranged on the surface of the pressing pump;

[0007] The upper cover is provided with an opening, and a button is slidably arranged in the opening, a clamp ring is placed in the upper cover, and both ends of the clamp ring are fixed to the button;

[0008] The inner wall of the clamp ring contacts the surface of the pressing pump, a fixing sleeve is sleeved on the surface of the pressing pump, and the bottom of the clamp ring corresponds to the upper side of the fixing sleeve.

[0009] When the upper cover is flush with the top of the pump, the pump cannot be pressed due to the obstruction of the upper cover, thereby avoiding accidental touch. By moving the upper cover downward to expose the pressing cap of the pump, the pump can be used to extract the solution in the bottle.

[0010] When the upper cover is flush with the top of the press pump, the bottom of the clamping ring contacts the upper side of the fixing sleeve, and the clamping ring is blocked by the fixing sleeve, so that the upper cover and the clamping ring cannot move downward. By pressing a button inside the upper cover, the clamping ring changes from an elliptical shape to a circular shape. At this time, the bottom of the clamping ring no longer corresponds to the upper side of the fixing sleeve. After the obstruction of the clamping ring is released, the upper cover and the clamping ring can be moved downward to expose the pressing cap of the press pump.

[0011] After the upper cover and the clamping ring move downward, the clamping ring enters the annular groove, and the clamping ring elastically contracts to cooperate with the clearance of the annular groove. The cooperation between the clamping ring and the clearance of the annular groove can limit the upper cover.

[0012] Preferably, a fixing ring is sleeved on the surface of the fixing sleeve, and the bottom of the fixing ring contacts the top of the bottle body.

[0013] Preferably, a clamping plate is provided on the clamping ring, clamping grooves are provided on the upper cover and the fixing ring, and two sides of the clamping plate are respectively plugged into the two clamping grooves.

[0014] Preferably, a support plate is provided on the fixing ring, and the support plate corresponds to the button.

[0015] Preferably, the clamping ring is elastic.

[0016] Preferably, an annular groove is provided on the surface of the fixing sleeve, and the annular groove is matched with the clamping ring.

[0017] Preferably, a groove is provided on the top of the upper cover, and the cap mouth of the pressing pump is adapted to the groove and is located above the groove.

[0018] Preferably, the upper cover slides along the height direction of the pressing pump.

[0019] The beneficial effects are:

[0020] The upper cover blocks the pressing pump, so that the pressing pump can be prevented from being accidentally touched. By pressing the button, the clamping ring changes from an elliptical shape to a circular shape. At that time, the bottom of the clamping ring no longer corresponds to the upper side of the fixing sleeve, thereby releasing the obstruction of the clamping ring. The upper cover and the clamping ring can be moved downward to expose the pressing cap of the pressing pump for use. By pressing the button, the upper cover is moved upward, and the upper cover is used to cover the pressing cap to prevent accidental touching.

[0021] The entire process can be operated with one hand. Hold the bottle body, put the index finger on the side of the upper cover, and press the button with the thumb. The thumb and index finger can cooperate to move the upper cover vertically to open and close the device. The operation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0032] See also Figure 1-Figure 6 As shown, the utility model provides a pump with a sunken opening cover, comprising a press pump 1 and a bottle body 4, the press pump 1 is installed on the bottle body 4, and an upper cover 2 is arranged on the surface of the press pump 1;

[0033] An opening 7 is provided on the upper cover 2, and a button 3 is slidably arranged in the opening 7. A clamp ring 6 is placed in the upper cover 2, and both ends of the clamp ring 6 are fixed to the button 3.

[0034] The inner wall of the clamp ring 6 contacts the surface of the pressing pump 1 . The surface of the pressing pump 1 is sleeved with a fixing sleeve 5 . The bottom of the clamp ring 6 corresponds to the upper side of the fixing sleeve 5 .

[0035] As an optional embodiment, a fixing ring 8 is provided on the surface of the fixing sleeve 5, and the bottom of the fixing ring 8 contacts the top of the bottle body 4. The fixing ring 8 can increase the contact area between the pressing pump 1 and the bottle body 4, thereby improving the sealing between the pressing pump 1 and the bottle body 4.

[0036] A clamping plate 12 is provided on the clamping ring 6, and clamping grooves 10 are provided on the upper cover 2 and the fixing ring 8, and the two sides of the clamping plate 12 are respectively plugged into the two clamping grooves 10. The clamping plate 12 cooperates with the clamping grooves 10 to improve the stability of the clamping ring 6, and the clamping plate 12 also has a fulcrum function, and cooperates with the pressing of the button 3 to make the clamping ring 6 easier to deform.

[0037] A support plate 9 is provided on the fixing ring 8, and the support plate 9 corresponds to the button 3;

[0038] The support plate 9 is used to limit the pressing stroke of the button 3 to prevent the button 3 from being pressed too deeply and completely separated from the opening 7 and stuck in the upper cover 2 without being able to rebound.

[0039] The snap ring 6 is elastic and deforms under the action of external force, thereby realizing switching between an elliptical shape and a circular shape. In the elliptical shape, its bottom corresponds to the upper side of the fixing sleeve 5, and in the circular shape, it can be separated from the fixing sleeve 5.

[0040] An annular groove 11 is provided on the surface of the fixing sleeve 5, and the annular groove 11 is adapted to the snap ring 6. After the upper cover 2 and the snap ring 6 move downward, the snap ring 6 enters the annular groove 11, and the snap ring 6 elastically contracts to fit with the gap of the annular groove 11. The gap between the snap ring 6 and the annular groove 11 can limit the upper cover 2 and improve the stability of the upper cover 2.

[0041] A groove 13 is formed on the top of the upper cover 2, and a cap mouth 15 of the press pump 1 is adapted to the groove 13 and is located above the groove 13;

[0042] The groove 13 has two functions. On the one hand, the groove 13 can block the cap mouth 15. On the other hand, the groove 13 can limit the upper cover 2. The cap mouth 15 blocks the groove 13. After the upper cover 2 is flush with the top of the pressing pump 1, it cannot move upward further, preventing the upper cover 2 from separating from the pressing pump 1 and causing loss.

[0043] The upper cover 2 slides along the height direction of the pressing pump 1, and the pressing pump 1 can guide the upper cover 2, so that the upper cover 2 is more stable when moving vertically.

[0044] With the above structure, when the upper cover 2 is flush with the top of the push pump 1, the push pump 1 cannot be pressed due to the obstruction of the upper cover 2, thereby avoiding accidental touch. By moving the upper cover 2 downward to expose the push cap 14 of the push pump 1, the push pump 1 can be used to pump out the solution in the bottle body 4.

[0045] When the upper cover 2 is flush with the top of the pressing pump 1, the bottom of the snap ring 6 contacts the upper side of the fixing sleeve 5, and the snap ring 6 is blocked by the fixing sleeve 5, so that the upper cover 2 and the snap ring 6 cannot move downward. By pressing the button 3 inside the upper cover 2, the snap ring 6 changes from an elliptical shape to a circular shape. At this time, the bottom of the snap ring 6 no longer corresponds to the upper side of the fixing sleeve 5. After the obstruction of the snap ring 6 is released, the upper cover 2 and the snap ring 6 can be moved downward to expose the pressing cap 14 of the pressing pump 1.

[0046] After the upper cover 2 and the snap ring 6 move downward, the snap ring 6 enters the annular groove 11 , and the snap ring 6 elastically contracts to fit with the annular groove 11 . The gap between the snap ring 6 and the annular groove 11 can limit the upper cover 2 .

[0047] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
