Description of Related Arts

The spray bottle has been widely used in various industries and technical fields, such as the fields of chemical engineering, medicine, food and the like. According to the actual requirement, some spray bottles have relative high material requirements, while the use of the spray bottle cap is limited to seal the liquid inside, or limited to the dust suppression effect. In medicine, there are often some liquid medicines, such as cough syrup, rhinitis spray, beriberi spray and the like, and the spray bottle for containing those liquid medicines should be configured with not only an inner lid but also an outer lid, where the inner lid is capable of covering the opening thereof and spraying liquid, and the outer lid is capable of covering the outlet port of the inner lid. Also, the outer lid should not only serve to the dust suppression effect, but non-easy falling out, lest it is opened and accidental ingested by an infant, which may become a life-threatening risk. In the field of chemical engineering of wash product line and cosmetic line, such as dish detergent, laundry detergent, shampoo, facial cleanser and the like, for the sake of health, convenience as well as security, currently, the liquid packaging form that the outlet port of the inner lid is further provided with an outer lid has been increasingly adopted.

In the spray bottle cap consisting of an inner lid and an outer lid of the prior art, it is often provided with a structure between the outer wall of the inner lid and the inner wall of the outer lid, where the structure is fitted by an arc-shaped groove and an arc-shaped boss to achieve the connection therebetween. If the fit is relative tight, it requires larger power to pull out the outer lid from the inner lid, which is unfavorable for the old; if the fit is relative loose, the outer lid is apt to fall off from the inner lid, with the result of poor safety. Some outer cap bodies and inner cap bodies are in the form of threaded connection, the structure of which is apt to be opened by infants, with the result of poor safety as well. The U.S. patent (U.S. Pat. No. 6,112,921) has disclosed a child-resistant closure, which comprises an upper end comprising an outer wall and an inner wall connected by an upper surface; the inner wall is provided with an inner thread matched with an outer thread of a container opening; the outer wall is provided with a notch; the lower end of the inner wall is provided an extended wall opposite to the notch of the outer wall; a shoulder of the container is provided with a sub-triangular boss, when the closure is covered, the inner thread of the inner wall of the closure is screwed with the outer thread of the container opening, the outer wall and the extended wall of the lower end of the inner wall is inserted by the sharp corner of the boss of the container shoulder, and is transformed under the action of the boss, and is recovered until the extended wall of the lower end of the inner wall is departed from the boss. When there is a need to open the closure, firstly the extended wall is pinched to make it transformed, then a gap larger than the width of back-end of the boss is formed between the extended wall and the outer wall, so that the closure is able to be opened. Such structure is safe and is unable to be opened by a child, whereas the operation is relative laborious, and is also difficult for the old to open, thereby causing inconvenient use.

Owing to the spray bottles for medicine and chemical wash product, the opening or closing actions therefor are either laborious in operation, non-easy for opening, which is inconvenience for old, or easy for opening but poor in security, which is likely to be opened and accidental ingested by infants. The inventors of the present invention design a spray bottle and a bottle cap thereof, which are provided with a screw-thread fit between a pressing head and a protective cap, as well as an anti-reversion snap structure for unlocking the pressing head and the protective cap by pressing action, so that the protective cap is not only reliably connected but also easy for opening. By designing a protrusion portion for the pressing head that enables to push against the upper face of the base lid, the pressing head avoids to be pressed downward when the spray bottle is in closed-lid state, thereby preventing the liquid leakage in the closed-lid state, with the result of good security. Also, by designing a first guide groove for the base lid, the protrusion portion of the pressing head enables to up-down slide along the first guide groove of the base lid to realize the extraction of liquid, which is labor-saving and convenience in operation.

Hereinafter, the spray bottle and the bottle cap thereof will be specifically illustrated in accordance with specific embodiments.

As shown inFIG. 1, the spray bottle of the present invention is made of plastic, or other elastically deformable materials, and comprises a base lid100, a protective cap200and a pressing head300.

As shown inFIGS. 4ato 4c, the inner wall of the base lid100is a shape of stepped holes of lower large-upper small, and comprises a light aperture section110, an anti-reversion inner ratchet section120, a screw hole section130and an outlet section140from the lower to the upper side. The upper end of the inner wall of the outlet section140is provided with a first limit rib142; the inner wall of the outlet section140is also provided with a first guide groove143penetrating the first limit rib142. The upper end face of the outlet section140is also provided with a first limit boss145configured in a same circumference with the first guide groove143.

For the sake of convenience in assembly, preferably, an upper corner angle of the first limit rib142is provided with a chamfer, and a lower corner angle of the first limit flange321ais provided with a chamfer.

As shown inFIG. 9, the spray bottle of the present invention consists of a bottle body2, a spray bottle cap1assembled at the mouth of the bottle body2, and a sprayer3. Wherein, the inner thread of the screw hole section130of the base lid100is matched with the outer thread of the mouth of the bottle body2, the anti-reversion inner ratchet section120of the base lid100is matched with the outer ratchet of the mouth of the bottle body2; the match of the inner and outer ratchets may prevent the reverse rotation of the base lid100relative to the mouth of the bottle body2such that the base lid100is reliably connected to the mouth of the bottle body2, and is less to disengage. The sprayer3is configured between the base lid100and the bottle body2, where the outlet core3aof the sprayer3is inserted into the outlet rod322of the pressing head300, and the inlet core3bof the sprayer3is inserted to the bottom of the bottle body2. Inside the sprayer3is also provided with a reset spring3c, by which the outlet core3ais in a protruding state, to prevent the liquid in the sprayer3returning to the check valve3dinside the bottle body2.

As shown inFIG. 5atoFIG. 9, when the protective cap200is in a closing-lid state, the inner thread221of the protective cap200is tighten with the outer thread322aof the pressing head300, at this point, the anti-reversion snap daughter body211of the protective cap200is snap-fit with the anti-reversion snap parent body of the pressing head300, to limit the reverse rotation of the protective cap200, so that the protective cap200is locked to the pressing head300from being less to disengage. At this point, the first guide boss321bof the pressing head300is detached from the first guide groove143of the base lid100and is located above the first limit rib, the side face of the first guide boss321bis contacted with the first positioning boss145above the base lid100, the bottom face of the first guide boss321bplaced against the upper head surface of the outlet section140of the base lid, such that the pressing head300fails to press towards the base lid100, thereby preventing the liquid leakage in the closed-lid state, with the result of good security. When requiring for extracting liquid, the protective cap200is pressed downward, the outer ring210of the protective cap200is placed against the pressing handle313to cause transformation, i.e., the anti-reversion snap daughter body211is separated from the anti-reversion snap parent body311; in the meanwhile, the protective cap200is rotated, i.e., the match of threads between the protective cap200and the pressing head300is loosened, followed by rotating the pressing head300until the first guide boss321bis aligned with the first guide groove143of the base lid, then the pressing head300is pressed downward to make the outlet core3aof the sprayer3move downward, so as to realize the spray function of the sprayer3. As loosening the pressing head300, under the action of reset spring3c, the outlet core3ais protruded upward for restoration, with the result of driving the pressing head300move upward for restoration. During the restoration process of the outlet core3a, the check valve3din the sprayer is automatically opened under the action of differential pressure, and the liquid in the bottle body2enters into the sprayer3to realize the internal supplement of liquid. After the liquid spray, the protective cap200is retightened to the pressing head300by the screw-thread fit until the anti-reversion snap daughter body211of the protective cap200is slid into the anti-reversion snap parent body311of the pressing head300, to realize the reliable connection between the protective cap200and the pressing head300, and the rotation is not readily to occur as well. In the meanwhile, since the restored first guide boss321bof the pressing head300is disconnected with the first guide groove143of the base lid under the action of the reset spring3c, the pressing head300is rotated along with the protective cap200, so that the first guide boss321bof the pressing head300is placed against the upper head face of the outlet section140of the base lid and the first positioning boss145, to make the pressing head300fail to press downward. Accordingly, the spray bottle cap of the present invention is safe, and is labor-saving and convenient in operation, which is easy to use for olds.

FIGS. 10 to 14are shown to a second embodiment of the spray bottle cap in accordance with the present invention, compared to the first embodiment as shown inFIGS. 1 to 9, the present embodiment mainly has two aspects of improvement.

On the one hand, as shown inFIG. 10toFIG. 12, inside the first neck bush144of the base lid100is further provided with a length of guide bush146extended upward, a lower end of the guide bush146is integrally connected to the inner wall of the first neck bush144, and an upper end of the guide bush146is inserted in an inner cavity of the outlet rod322. As such, the guide bush146may form a guide support to the pressing head, so that the pressing head is resistant to snap during the pressing process.

On the other hand, as shown inFIG. 10toFIG. 14, the first guide boss321b(as shown inFIG. 6a) and the first positioning boss145(as shown inFIG. 4a) at the upper end face of the outlet section140of the base lid are cancelled in the present embodiment. In the present embodiment, the first guide boss321bis substituted by the second positioning boss316(as shown inFIG. 7a) between the inner ring and outer ring of the connection portion of the pressing head as a protrusion portion. As shown inFIG. 10, the second positioning boss316is located above the first limit rib142and deviated away from the first guide groove143in a stochastic situation, and fails to move downward by the blocking of the first limit rib142, so that the pressing head300fails to be pressed downward. Only if the second positioning boss316is aligned with the first guide groove143of the base lid, the second positioning boss316is up-down slidable along the first guide groove143, so that the pressing head300enables to be pressed downward. More preferably, the outer wall of the first neck bush144is provided with a third positioning boss147(as shown inFIG. 11), and the inner wall of the pressing head300is provided with a fourth positioning boss323(as shown inFIG. 14); when the pressing head300is un-pressed, the pressing head300is rotating against the base lid100, and the fourth positioning boss is placed against the third positioning boss, and thus the rotation may no longer proceed. At this point, the protrusion portion (i.e., the second positioning boss316) is located at the position deviated away from the first guide groove143, by such, the pressing head300fails to be pressed, thereby preventing the press of the pressing head300by misoperation in the non-use state of the spray bottle, so as to decrease the probability of liquid leakage.

In summary, the spray bottle and the bottle cap of the present invention have good security, avoid to be inadvertently opened and accidental ingested by infants, and is labor-saving and convenience in operation, and easy for olds as well.
