Description

Dispenser and container including the same

Cross-reference to related applications

The present application is based on a Chinese patent application filed on Jan. 20, 2015, the entire disclosure of which is hereby incorporated by reference.

Technical field

The present invention relates to a dispenser for a container, and in particular to a container comprising the dispenser. The container is particularly intended to contain a cosmetic liquid.

Background technique

There are currently a variety of containers for containing and storing cosmetic liquids.

One of the most basic types of containers does not have a dispenser in which the liquid is contained. When it is necessary to take a liquid, it is necessary to turn the container upside down to pour the liquid out of the opening. The use of such a container is inconvenient for the user; the amount of liquid cannot be controlled each time it is used; and the opening of the container is not hygienic because it is often touched.

Another prior container includes the most conventional dropper that is secured in the cap and has a rubber ball tip at the top. In one type of container, the rubber ball head extends through the cap and is exposed. In this case, the exposed rubber ball head may be unintentionally squeezed, and on the other hand, the rubber ball head is exposed to the outside and the rubber is easily aged quickly. Moreover, such containers are not aesthetically pleasing. For cosmetics, aesthetics is an important factor to consider when faced with consumer choice. There is another type of container in which the rubber ball head is placed under the button and can be compressed by pressing a button. With the above two types of containers, it is not guaranteed that a precise amount of cosmetic liquid can be taken each time it is used, because the user may apply a pressing force each time. Different, careless users may even squeeze into the rubber ball head or press the button when the cap is not fully engaged with the container. And especially for expensive cosmetic liquids, it is very desirable to take the liquid in precise amounts each time.

In addition, a dispenser of the dropper type has been developed in which the housing of the cap can be rotated to draw liquid and the button on the cap can be pressed to squeeze the liquid for use. However, such an existing dispenser has a very complicated structure including at least 10 components, so the cost of the container is greatly increased.

Summary of the invention

The present invention proposes a dispenser and a container to at least solve the above mentioned problems.

According to an aspect of an embodiment of the present invention, a dispenser is provided, comprising:

a rotatable housing having a slope on an inner wall surface thereof;

detailed description

Figures 1 and 2 show a container 1000 comprising a dispenser according to a first embodiment of the invention.

As shown in Figures 1 and 2, the container 1000 includes a dispenser 1100 for holding a liquid and a container body 1200. As shown in FIG. 3, the dispenser 1100 includes a substantially coaxially mounted button 1110, a housing 1120, a piston 1130, an elastic member 1140, a fixture 1150, and a dropper 1160.

As shown in Figures 5 and 6, the fixing member 1150 has a substantially cylindrical shape and is provided with internal threads. The container body 1200 is substantially cylindrical and is provided with corresponding external threads. Thereby the fixing part 1150 can be screwed to the container body 1200 by means of internal threads.

The fixture 1150 is mounted within the housing 1120 and the housing 1120 can be rotated relative to the fixture 1150. The fixture 1150 has four longitudinal rails 1151. The inner wall of the piston 1130 is provided with four corresponding longitudinal recesses that cooperate with the longitudinal rails. The piston 1130 is sleeved on the fixing member 1150. Due to the engagement of the recess with the longitudinal rail, the piston 1130 is non-rotatable relative to the fixture 1150, but is vertically slidable along the longitudinal rail 1151. It will be appreciated that the number of longitudinal rails and corresponding recesses may also be other than four.

The housing 1120 is provided with a guide on its inner wall, which can be in the form of a sloped slide, ie a ramp. Preferably, the guiding portion comprises a plurality of axially symmetrically arranged ramps. In a first embodiment in accordance with the invention, the housing 1120 includes two ramps 1121. Only one of the ramps 1121 is shown in the cross-sectional view of the housing of FIG. Each of the slopes has an upper end portion 1121a and a lower end portion 1121b.

The piston 1130 has a pair of rounded protrusions 1131, an upper end portion 1121a and a lower end portion 1121b pair The stop of the protrusion 1131 defines an extreme position of relative rotation between the housing 1120 and the piston 1130. In addition, on the slope near the upper end portion 1121a and the lower end portion 1121b, corresponding protrusions may be respectively provided (only the protrusion portion 1121c on the side of the upper end portion 1121a is shown in FIG. 4), Thereby, in the released state, the protrusion 1131 relatively stably stays at the corresponding upper end portion 1121a (as shown in FIG. 5), and in the pressed state, the protrusion 1131 relatively stably stays at the corresponding lower end portion 1121b. (as shown in Figure 6). Thus, when the protrusion 1131 is at the upper end portion 1121a or the lower end portion 1121b, the unintentional touch does not allow the protrusion 1131 to easily leave the upper end portion 1121a or the lower end portion 1121b. In other words, the housing 1120 is not unintentionally rotated.

The elastic member 1140 includes or is made of an elastic material having a compressible chamber and being fixed to the fixture 1150. The bottom of the resilient member 1140 is sealed against the container body 1200. The dropper 1160 is sealingly coupled to the resilient member 1140, and the lumen of the dropper 1160 is in fluid communication with the lumen of the resilient member 1140.

The operation of the dispenser 1100 is described below.

The dispenser 1100 is first secured to the container body 1200 by means of the threads of the fastener 1150. Typically, the dispenser 1100 is coupled to the container body 1200, for example, by a threaded screw in a clockwise direction. At this time, the dispenser 1100 is in the released state shown in FIG.

When the dispenser 1100 is continued to rotate in the clockwise direction, the slope 1121 on the inner wall of the housing 1120 applies a force including a circumferential direction component and a vertical downward direction component to the rounded protrusion 1131 of the piston 1130. Since the fixture 1150 is fixed relative to the container body 1200 and the piston 1130 is unable to rotate relative to the fixture 1150, only the vertically downward component force pushes the piston 1130 downward as the housing 1120 rotates. The piston 1130 thus moves vertically downward along the longitudinal rails on the fixture 1150. During this process, the rounded protrusion 1131 of the piston 1130 exits the upper end portion 1121a of the ramp 1121 and always abuts against the ramp 1121 that is slid over it. In short, when the housing 1120 is rotated clockwise, the rotating ramp 1121 pushes the piston 1130 downward. At the same time, since the diameter of the upper opening of the piston 1130 is smaller than the diameter of the lower portion of the button 1110, the downward movement The piston 1130 drives the button 1110 to move downward, whereby the button 1110 presses the elastic member 1140 downward.

In the above process, since the elastic member 1140 is pressed, a positive pressure is formed in the inner cavity thereof, thereby pushing out the air or liquid present in the inner cavity and the dropper 1160 connected to the elastic member 1140. Finally, when the lower end portion 1121b of the slope 1121 of the housing 1120 contacts the rounded protrusion 1131 of the piston 1130, the housing 1120 cannot be further rotated and the rotation is stopped. At this time, the dispenser 1100 is in a pressed state as shown in FIG.

Then, when the housing 1120 is rotated in the counterclockwise direction from the pressed state shown in FIG. 6, the rounded protrusion 1131 leaves the lower end portion 1121b of the slope 1121. During the counterclockwise rotation of the housing 1120, the lower region of the ramp 1121 is gradually rotated away from the rounded protrusion 1131 of the piston 1130; the compressed resilient member 1140 gradually expands back and pushes the button 1110 upward. At this time, the button 1110 drives the piston 1130 to move upward. During this process, as the elastic member 1140 gradually expands and recovers, its inner cavity gradually expands and establishes a negative pressure therein and in the dropper 1160 connected to the elastic member 1140. This negative pressure causes the contents of the container to be drawn into the dropper 1160 from the inlet at the bottom end of the dropper 1160. Finally, when the upper end portion 1121a of the slope 1121 of the housing 1120 contacts the rounded projection 1131 of the piston 1130, the dispenser 1100 reaches the released state as shown in FIG. At this time, the contents, such as a cosmetic liquid, are sucked into the dropper 1160.

In the above process, the dispenser 1100 is always fixed to the container body 1200 by means of the threads of the fixing member 1150.

After reaching the released state as shown in FIG. 5, the housing 1120 on the dispenser 1100 can still continue to rotate counterclockwise relative to the container body 1200. The housing 1120 that is further rotated at this time pushes the rounded protrusion 1131 by its upper end portion 1121a to rotate the piston 1130, and the piston 1130, in turn, pushes the fixing member 1150 to rotate counterclockwise by the engagement of the recess with the longitudinal rail 1151 of the fixing member 1150. Therefore, the further rotation will gradually release the threaded connection between the fixing member 1150 and the container body 1200, that is, gradually remove the gap between the dispenser 1100 and the container body 1200. Threaded connection. The final dispenser 1100 is detached from the container body 1200. When the dispenser 1100 is completely removed from the container body 1200, the user can press the button 1110 to squeeze the contents out of the dropper 1160 for use.

In the above process, the user can hold the container body by one hand, for example, and the other hand rotates the housing of the dispenser to complete the operation. Of course, the user can only use the thumb and forefinger to grip and rotate the dispenser and use other fingers to hold the container body in the palm position.

In the embodiment described above, the piston 1130 and the button 1110 are configured such that the diameter of the upper opening of the piston 1130 is smaller than the diameter of the lower portion of the button 1110, whereby the button 1110 can move downward with the piston 1130, and the piston 1130 can follow The button 1110 moves up. It will be appreciated, however, that the piston 1130 and button 1110 can be disposed in any other manner as long as the downward movement of the piston can cause the button to move downwardly and the upward movement of the button can cause the piston to move upward. For example, the piston and button can be rigidly connected. Alternatively, referring to Figures 7 and 8, the piston 2130 and the button 2110 are integrally formed as a single piece. In this case, the number of parts of the dispenser according to the embodiment of the present invention is further reduced, and the structure is further simplified.

In the above embodiment, the elastic member 1140 is shown in the drawing as a rubber ball head having corrugations. It will be appreciated, however, that the resilient member may take other forms as long as a positive pressure is established in its internal chamber when compressed, while pushing the button up and establishing a negative pressure in the chamber upon recovery. For example, the elastic member may alternatively be merely a rubber ball head or just a bellows.

The invention has been described above with reference to the embodiments, but it should be noted that the embodiments described above are illustrative and not restrictive. The various technical features described in the above-described embodiments can be combined and used arbitrarily in different embodiments without being mutually inconsistent. It will be appreciated by those skilled in the art that various changes may be made without departing from the spirit and scope of the invention.
