Description

Exit device to prevent ointment from spilling

The present invention relates to an outlet device, in particular to an outlet device for preventing ointment from overflowing.

A large number of paste products in tube packaging are used in daily life, such as toothpaste, skin cream, ointment, etc., and their contents are all contained in a squeeze bottle. When using, the squeeze bottle must be squeezed manually so that the contents are squeezed and overflow from the outlet. Generally, a seal is provided on the squeeze bottle, and the seal is fixed in the squeeze bottle in a spiral fixing manner or in a buckled structure. Before use, the seal often needs to be manually unscrewed or pried open to squeeze the contents out of the squeeze bottle. After the contents are used up, the seal is repeated.

Among them, there are some medicines, which use squeeze bottles made of metal, such as eye ointments, oral ointments, etc. The material of the squeeze bottle is relatively inelastic. After the squeeze bottle is squeezed flat, its shape is fixed and will not rebound. In addition, the medicine contained in the squeeze bottle is a relatively thick ointment. When the squeeze bottle is squeezed by external force, the ointment will continue to flow out. Often, after the user removes the ointment at the bottle mouth, the ointment still overflows, resulting in a lot of ointment attached to the bottle mouth after the cap is combined with the squeeze bottle, which not only causes waste of medicines, but also raises concerns about health and safety.

In addition, the internal pressure of the squeeze bottle that has been squeezed and deformed still exists, causing the ointment to burst out from the outlet after the cap is opened, which will cause the user to be in a hurry and eventually cause the drug to remain at the bottle mouth and the cap. In addition, pharmaceutical products are usually small in size and are easy to be lost after the cap is opened, which will also cause trouble to the user.

From the above description, it can be seen that the use of squeeze bottles currently on the market has the following disadvantages:

1. Bottle caps are easy to lose: Generally, products such as eye ointments or oral ointments are small in size, and the caps on the squeeze bottles are even smaller. After the squeeze bottle is opened, the caps are easy to lose, and the small caps are difficult to find after falling to the ground. The medicines that lose the caps cannot be preserved.

2. Waste of medicines: In order to preserve some medicines, the squeeze bottle is made of metal with relatively inelastic material. When the squeeze bottle is squeezed, it will deform and will not rebound by the internal pressure. Because the medicine is a thicker paste, the speed of the medicine flowing out is relatively slow, causing the medicine to continue to come out when used. The amount of medicine squeezed out is often more than the amount used, which will cause waste of medicines.

3. Safety and health concerns: As mentioned above, when there is positive pressure inside the squeeze bottle, the ointment will burst out crazily after the cap is opened, causing panic among users and causing ointment residue to remain at the outlet of the squeeze bottle and the entire cap, making the squeeze bottle prone to bacterial residues, which raises safety and health concerns.

Therefore, how to seal the squeeze bottle without using a cap and avoid the adhesion of the ointment, so as to avoid waste and maintain safety and hygiene, is a goal that relevant technical personnel urgently need to work hard on.

In view of this, the purpose of the present invention is to provide an outlet device for preventing ointment from overflowing, which is suitable for being arranged in a squeeze bottle and can immediately prevent the ointment in the squeeze bottle from overflowing.

The ointment overflow prevention device comprises a fixed unit and a movable unit.

The fixing unit includes an inner shell arranged on the extrusion bottle and a first inner hole arranged on the inner shell.

The movable unit includes an outer shell that contacts the outer surface of the inner shell and moves, and an outer hole arranged on the outer shell. The outer shell can move between a first open position and a closed position relative to the inner shell. When the outer shell is at the first open position relative to the inner shell, the outer hole is aligned with the first inner hole and communicates with each other. When the outer shell is at the closed position relative to the inner shell, the outer shell covers the first inner hole.

Another technical means of the present invention is that the above-mentioned outlet device for preventing ointment from overflowing further includes an alignment unit, and the alignment unit includes a first position indicator set on the extrusion bottle, and the first position indicator cooperates with the setting position of the first inner hole.

Another technical means of the present invention is that the above-mentioned alignment unit further includes a moving position indicator arranged on the outer shell, the moving position indicator and the setting position of the outer hole cooperate with each other, and the moving position indicator is a protrusion arranged on the side of the outer shell.

Another technical means of the present invention is that the movable unit further includes a thread arranged on the periphery of the outer shell.

Another technical means of the present invention is that the movable unit further includes a rotation force applying part arranged on the periphery of the outer shell.

Another technical means of the present invention is that the fixing unit further includes an outer edge side wall arranged on the inner shell and connected to the extrusion bottle, and an arc-shaped top wall arranged on the inner shell and connected to the outer edge side wall, the outer edge side wall and the arc-shaped top wall cooperate to make the inner shell have a bell-shaped appearance, and the first inner hole is arranged on the side of the arc-shaped top wall.

Another technical means of the present invention is that the movable unit further includes a tip portion arranged on the outer side of the outer shell, the tip portion is arranged far away from the extrusion bottle, the inner structure of the outer shell matches the outer appearance of the inner shell, and the outer hole connects the inner part of the outer shell and the tip portion.

Another technical means of the present invention is that the above-mentioned fixing unit further includes a second inner hole arranged in the inner shell, the first inner hole and the second inner hole are arranged at intervals, and the outer shell can be moved to a second opening position relative to the inner shell. When the outer shell is at the second opening position relative to the inner shell, the outer hole is aligned with the second inner hole.

Another technical means of the present invention is that the diameters of the first inner hole and the second inner hole are different.

Another technical means of the present invention is that the alignment unit further includes a second position indicator disposed on the extrusion bottle, and the second position indicator cooperates with the setting position of the second inner hole.

The beneficial effect of the present invention is that the outer shell arranged outside the inner shell can move along the outer surface of the inner shell. When the outer shell is at the first open position relative to the inner shell, the ointment contained in the squeeze bottle can overflow from the first inner hole and the outer hole. When the outer shell is at the closed position relative to the inner shell, the outer shell blocks the ointment contained in the squeeze bottle so that the ointment will not overflow.

The patent features and technical contents of the present invention are clearly presented in the following detailed description of five preferred embodiments with reference to the drawings. Before the detailed description, it should be noted that similar components are represented by the same numbers.

Referring to FIG. 1 , there is shown a first preferred embodiment of an outlet device for preventing ointment from overflowing according to the present invention. The outlet device for preventing ointment from overflowing is suitable for being disposed on an extrusion bottle 21 and uses a sealing cap 22 disposed on the extrusion bottle 21.

The outlet device for preventing the ointment from overflowing comprises a fixed unit 31 and a movable unit 32. The fixed unit 31 is fixed on the extrusion bottle 21 and cannot rotate or move relative to the extrusion bottle 21. The movable unit 32 is sleeved on the fixed unit 31 and can rotate relative to the fixed unit 31.

Referring to FIG. 2 , the fixing unit 31 includes an inner shell 311 disposed on the extrusion bottle 21, a first inner hole 312 disposed on the inner shell 311, an outer edge side wall 313 disposed on the inner shell 311 and connected to the extrusion bottle 21, and an arc-shaped top wall 314 disposed on the inner shell 311 and connected to the outer edge side wall 313. The outer edge side wall 313 cooperates with the arc-shaped top wall 314 to make the inner shell 311 roughly bell-shaped in appearance. The first inner hole 312 is disposed on the side of the arc-shaped top wall 314, which can facilitate the extrusion bottle 21 to squeeze out the medicine and apply it to the wound or inflamed area.

Referring to FIG. 3 , the movable unit 32 includes an outer shell 321 that contacts the outer surface of the inner shell 311 and moves, an outer hole 322 disposed on the outer shell 321, a thread 323 disposed on the periphery of the outer shell 321, and a rotation force-applying portion 324 disposed on the periphery of the outer shell 321. The thread 323 is provided for the sealing cap 22 to be screwed. In actual implementation, the sealing cap 22 may not be disposed on the extrusion bottle 21, and the movable unit 32 may not be disposed on the thread 323, but this should not be limiting. The rotation force applying part 324 provides a user with force to move the outer shell 321 relative to the inner shell 311. In the first preferred embodiment, the rotation force applying part 324 is a bump protruding from the surface of the outer shell 321. The outer shell 321 can be rotated by turning the rotation force applying part 324. In actual implementation, this should not be limited to this.

Please refer to Figures 1, 2 and 3. The outer shell 321 can move between a first open position and a closed position relative to the inner shell 311. When the outer shell 321 is at the first open position relative to the inner shell 311, the outer hole 322 is aligned with the first inner hole 312 and communicates with each other (as shown in Figure 1), so that the ointment contained in the extrusion bottle 21 can be squeezed out. When the outer shell 321 is at the closed position relative to the inner shell 311, the outer shell 321 covers the first inner hole 312 to prevent the ointment contained in the extrusion bottle 21 from overflowing. Even if there is still positive pressure in the extrusion bottle 21, the ointment can be prevented from overflowing, thereby avoiding excessive ointment from overflowing and causing waste.

Please refer to FIG. 4 , which is a second preferred embodiment of an outlet device for preventing ointment from overflowing of the present invention. The second preferred embodiment is substantially the same as the first preferred embodiment, and the similarities are not described in detail here. The difference is that the outlet device for preventing ointment from overflowing further includes an alignment unit 33, and the alignment unit 33 includes a first position indicator 331 disposed on the extrusion bottle 21, and the first position indicator 331 cooperates with the setting position of the first inner hole 312.

In the second preferred embodiment, the rotation force applying portion 324 is a sawtooth surface arranged around the surface of the outer shell 321, the first position indicator 331 is a black dot arranged on the extrusion bottle 21, the inner shell 311 is fixed on the extrusion bottle 21 and cannot be rotated or moved relative to the extrusion bottle 21, and the angle position of the first inner hole 312 matches the angle position of the first position indicator 331, so the user only needs to rotate the outer hole 322 on the outer shell 321 to the angle of the first position indicator 331, so that the outer shell 321 can be at the first opening position relative to the inner shell 311, so that the outer hole 322 is aligned with the first inner hole 312.

Please refer to Figure 5, which is a third preferred embodiment of an outlet device for preventing ointment from overflowing of the present invention. The first preferred embodiment is substantially the same as the second preferred embodiment, and the similarities are not described in detail here. The difference is that the alignment unit 33 further includes a moving position indicator 332 disposed on the outer shell 321, and the moving position indicator 332 cooperates with the setting position of the outer hole 322. The moving position indicator 332 is a protrusion disposed on the side of the outer shell 321, wherein the moving position indicator 332 replaces the rotating force applying portion 324 in the first preferred embodiment.

The movable position indicator 332 is fixed to the outer shell 321. When the outer shell 321 is rotated, the movable position indicator 332 will rotate synchronously. The setting angle position of the movable position indicator 332 is matched with the setting angle position of the outer hole 322. In addition, the angle position of the first inner hole 312 is matched with the angle position of the first position indicator 331. Therefore, the user only needs to rotate the movable position indicator 332 to the first position indicator 331, and the outer hole 322 can be aligned with the first inner hole 312 to provide the ointment to flow out.

Please refer to Figures 5 and 6, which are a fourth preferred embodiment of an outlet device for preventing ointment from overflowing of the present invention. The fourth preferred embodiment is substantially the same as the third preferred embodiment, and the similarities are not described in detail herein. The difference is that the fixing unit 31 further includes a second inner hole 315 disposed in the inner shell 311, the first inner hole 312 and the second inner hole 315 are spaced apart, and the outer shell 321 can be moved to a second opening position relative to the inner shell 311. When the outer shell 321 is at the second opening position relative to the inner shell 311, the outer hole 322 is aligned with the second inner hole 315. The first inner hole 312 and the second inner hole 315 have different diameters. The alignment unit 33 further includes a second position indicator 333 disposed on the extrusion bottle 21. The second position indicator 333 and the second inner hole 315 are matched with each other. The first inner hole 312 and the second inner hole 315 are disposed on the side of the arc-shaped top wall 314, which can facilitate the extrusion bottle 21 to squeeze out the medicine and apply it to the wound or inflamed area.

In the fourth preferred embodiment, the setting position of the first position indicator 331 is at the same angle as the setting position of the first inner hole 312, and the pattern shape of the first position indicator 331 is similar to the opening shape of the first inner hole 312. The setting position of the second position indicator 333 is at the same angle as the setting position of the second inner hole 315, and the pattern shape of the second position indicator 333 is similar to the opening shape of the second inner hole 315. When the moving position indicator 332 moves to the angle of the first position indicator 331, the housing 3 21 moves to the first opening position, and the outer hole 322 is aligned with the first inner hole 312 and communicates with each other. When the moving position indicator 332 moves to the angle of the second position indicator 333, the outer shell 321 can be moved to the second opening position, and the outer hole 322 is aligned with the second inner hole 315 and communicates with each other. When the moving position indicator 332 moves to a position other than the first opening position and the second opening position, the outer shell 321 can be moved to the closed position, and the outer shell 321 covers the first inner hole 312.

Please refer to FIG. 7, which is a fifth preferred embodiment of an outlet device for preventing ointment from overflowing according to the present invention. The fifth preferred embodiment is substantially the same as the fourth preferred embodiment, and the similarities are not described in detail here. The difference is that the movable unit 32 further includes a tip portion 325 disposed on the outer side of the housing 321, and the tip portion 325 is disposed at a position far from the extruder. The inner structure of the outer shell 321 of the squeeze bottle 21 matches the outer appearance of the inner shell 311, and the outer hole 322 connects the inner part of the outer shell 321 and the tip 325. Since the outer diameter of the tip 325 is a gradual structure from the position of the squeeze bottle 21 to the outside, it is similar to the opening structure of commercially available eye ointment medicines, which can facilitate users to apply the ointment to the diseased area or wound.

The fixed unit 31 further includes a recess 316 disposed at the bottom of the outer edge side surface of the inner shell 311, and the movable unit 32 includes a protrusion 326 disposed at the bottom of the inner edge surface of the outer shell 321. The recess 316 is disposed around the bottom of the outer edge side surface of the inner shell 311, and the protrusion 326 is clamped in the recess 316, so that the outer shell 321 can rotate relative to the inner shell 311.

When the outer shell 321 is at the first opening position relative to the inner shell 311, the outer hole 322 is aligned with the first inner hole 312 and communicates with each other, so that the ointment in the extrusion bottle 21 can flow out through the first inner hole 312 and the outer hole 322. When the outer shell 321 is at the second opening position relative to the inner shell 311, the outer hole 322 is aligned with the second inner hole 315 and communicates with each other, so that the ointment in the extrusion bottle 21 can flow out through the second inner hole 315 and the outer hole 322. When the inner shell 311 is in the closed position, the outer shell 321 simultaneously covers the first inner hole 312 and the second inner hole 315, thereby blocking the ointment in the extrusion bottle 21. Preferably, the first inner hole 312 and the second inner hole 315 are arranged on the side of the arc-shaped top wall 314, which can facilitate the extrusion bottle 21 to squeeze out the medicine and apply it to the wound or inflamed area. In actual implementation, the first inner hole 312 and the second inner hole 315 can also be arranged on the outer edge side wall 313, but it should not be limited to this.

From the above description, it can be seen that the outlet device for preventing ointment from overflowing of the present invention has the following effects:

1. No need to worry about the bottle cap being lost: When the outer shell 321 rotates to the closed position relative to the inner shell 311, the outer shell 321 can simultaneously seal the first inner hole 312 and the second inner hole 315, thereby preventing the ointment in the squeeze bottle 21 from overflowing. Therefore, the squeeze bottle 21 does not need to be provided with a seal 22. If the squeeze bottle 21 is provided with a seal 22, when the seal 22 is lost, the outlet device for preventing the ointment from overflowing can also prevent the ointment from overflowing.

2. Preventing waste of medicine: Since the squeeze bottle 21 is provided with the outlet device of the present invention for preventing the ointment from overflowing, when the squeeze bottle 21 is squeezed to make the medicine flow out, the user can immediately use the rotation force applying part 324 to rotate the outer shell 321 to the closed position. Even if there is positive pressure inside the squeeze bottle 21, the outer shell 321 can still prevent the medicine from being exposed, thereby providing the user with precise control of the amount of medicine flowing out to prevent the waste of medicine.

3. Maintaining the hygienic safety of drugs: Since the internal structure of the outer shell 321 cooperates with the external structure of the inner shell 311, the outer shell 321 can seal and block the first inner hole 312 and the second inner hole 315 in the closed position, so that the drugs in the squeeze bottle 21 will not be contaminated by the outside world, and the outlet of the squeeze bottle 21 or the surface of the outlet device that prevents the ointment from overflowing will not produce drug residues, effectively maintaining the hygienic safety of drugs.

In summary, the outer shell 321 can rotate relative to the inner shell 311, and by utilizing the first inner hole 312 and the second inner hole 315 on the inner shell 311 and the setting position of the outer hole 322 on the outer shell 321, the outlet device for preventing the ointment from overflowing can quickly block the medicine in the squeeze bottle 21, which can provide the user with precise control of the amount of medicine output and can effectively avoid the problem of medicine residues remaining on the surface, so that the purpose of the present invention can be achieved.

However, the above are only five preferred embodiments of the present invention, and should not be used to limit the scope of implementation of the present invention. In other words, all simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the invention description are still within the scope of the present patent.
