Description

Title of the invention: CONTAINER FOR AUTOMATIC LOADING OF CONTENTS FIELD OF THE INVENTION

[0001] The invention generally relates to a container for automatically loading and dispensing contents in liquid or gel form. CONTEXT

[0002] The statements contained in this section merely provide background information related to the present disclosure and may not constitute prior art.

[0003] The provision of eco-responsible and environmentally friendly solutions, which are designed and developed with environmental issues in mind, is becoming a major objective in an effort to address global challenges.

[0004] It is therefore essential to design more sustainable products that reduce the amount of materials used, replace existing materials with more environmentally friendly ones and use recyclable materials in order to reduce the carbon footprint of products.

[0005] Various containers are currently available for containing, storing and dispensing cosmetic liquids.

[0006] One type of container is equipped with a dispenser. The dispenser, particularly in the field of cosmetics or pharmacy, is intended to dispense products such as liquids, creams, gels and other viscous products. The dispenser generally comprises a dispensing device such as a dropper. The dispensing device is attached to the neck of a container and serves to withdraw the product contained in the container by means of a dip tube.

[0007] One type of dispenser is a dropper. The dropper is fixed in the neck of a container and has a rubber bulb on top. In one type of dispenser like this, the rubber bulb passes through the neck of the container and is exposed. In this case, the exposed rubber bulb can be accidentally squeezed, and the rubber may age quickly when exposed. In addition, this type of container is not aesthetically pleasing. For cosmetics, aesthetics are an important factor to consider when many choices are available to consumers. There is another type of container in which the rubber bulb is positioned under a button and can be squeezed by pressing the button. However, using both types of containers still does not guarantee the accurate amount of cosmetic liquid at each use, as the pressure applied by the user can vary, and careless users may even compress the rubber bulb or press the button before the dispenser is fully attached to the container. This precise dispensing of liquid is especially desirable for expensive cosmetic liquids.

[0008] It can be appreciated that there still exists a need for a more durable container for automatically loading contents in liquid or gel form, in which fewer components are used, and no metal springs or butyl rubber are used, and an accurate amount of the contents at each use is automatically guaranteed and, in this regard, the present invention substantially meets this need.

DETAILED DESCRIPTION

[0046] The following description is purely exemplary and is not intended to limit the present disclosure, its application or its uses.

[0047] The following detailed description of the present invention refers to the accompanying drawings, which illustrate specific embodiments in which the present invention may be implemented. These embodiments are described in sufficient detail to enable those skilled in the art to practice the present invention. It should be understood that various embodiments of the present invention are different from one another, but need not be mutually exclusive.

[0048] With respect to the terms used in the present invention, the general terms that are currently and widely used are chosen in consideration of the functions of the present invention. However, the meaning of the terms may be modified according to the intention of those skilled in the art, judicial precedent, the emergence of new technology, and the like. Furthermore, in some cases, a term may be chosen at the discretion of the applicant. In such cases, the meaning of the term will be described in detail in the relevant part of the description of the invention. Therefore, The terms used in the present invention shall be defined based on the meaning of the terms and the complete descriptions provided herein without being limited simply to the names of the terms.

[0049] In the present disclosure, when a certain part "includes" certain elements, unless explicitly stated otherwise, it means that other elements may be included, but not excluded.

[0050] Hereinafter, a container for automatically loading contents in the form of a liquid or gel according to one or more embodiments of the present invention will be described with reference to Figures 1 to 7.

[0051] Figures 1 and 2 illustrate a container 1000 including a dispenser 100 according to an embodiment of the present invention respectively in side views and an exploded view. An XYZ coordinate system is schematically represented in Figure 1.

[0052] As shown in Figures 1 and 2, the container 1000 comprises a bottle 6 for containing cosmetic liquids and a dispenser 100 for dispensing the liquids. As shown in [Fig.2], the dispenser 100 comprises a button 1, a resilient component 2 and a rotatable housing 3 comprising a dropper tube 300, which are mounted substantially coaxially. Optionally, the dispenser 100 may also include a flexible cap 4 which is attached to a free end of the dropper tube 300. In one example, the dispenser 100 includes or acts as a dropper. In the embodiment of the present invention, the bottle 6 is illustrated separately from a bottle neck 5, but those skilled in the art would readily understand that the bottle 6 may be formed integrally with a bottle neck 5. In other words, the neck 5 may be formed as a portion of the bottle 6, which is not shown in the figures.In this way, the number of parts of the container 1000 according to the embodiments of the present invention is further reduced, and the structure is further simplified.

[0053] Figure 1 shows side views of a container 1000 including a dispenser 100 according to an embodiment of the present invention, wherein in [Fig.1a], the dispenser 100 is fully engaged in the neck 5 of the bottle 6 and an elastic component 2 is in a decompressed state, and in [Fig.1b], the dispenser 100 is detached from the neck of the bottle but the elastic component 2 is compressed, and in [Fig.1c], the dispenser 100 is fully disengaged from the neck 5 of the bottle 6 and the elastic component 2 is decompressed. [Fig.3] shows an exploded view of a knob 1 and a rotatable housing 3 of the dispenser 100 according to an embodiment of the present invention. Figure 4 shows cross-sectional views of the container 1000 including the dispenser 100 according to one embodiment of the present invention, the dispenser 100 being in a fully engaged corresponding to [Fig. 1a], [Fig. 4a] being a sectional view taken in the XZ plane so as to show more clearly the engagement between the pivoting housing 3 and the neck 5 of the bottle 6, and [Fig. 4b] being a sectional view taken in the YZ plane so as to show more clearly the interlocking between the button 1 and the neck 5 of the bottle 6.

[0054] As shown in Figures 1 to 4, the rotary housing 3 is cylindrical and has an internal thread 35. The neck 5 of the bottle 6 is also cylindrical and has corresponding external threads 51. Therefore, the rotary housing 3 can be connected to the bottle 6 by screwing, so that the dispenser 100 can be engaged or disengaged with the bottle 6.

[0055] The knob 1 comprises an axially extendable collar 11 extending downwardly, and at least two elastic arm portions 12 extending axially from the collar 11. The elastic arm portions 12 are preferably arranged symmetrically or diagonally on the collar 11. At the lower end of the elastic arm portions 12, there is an inner wall portion 14 continuing axially downwardly from the elastic arm portions 12. A stop portion 15 extending radially outwardly from the elastic arm portions 12, and an outer wall portion 13 extending axially downwardly from the stop portion 15. The outer wall portion 13 is configured to be prevented from rotating relative to the inner peripheral surface of the rotary housing 3.The inner wall portion 14 includes a retaining bar 141 that extends radially inward from the inner peripheral surface.

[0056] As shown in [Fig.4a], the neck 5 of the bottle 6 has an opening 52 whose outer diameter is smaller than that of the external threads 51. The mouth 52 further comprises a ring 521 which extends radially outward from the outer peripheral surface thereof. The holding bar 141 is configured to slide on the ring 521 so as to snap into place.

[0057] The pivoting housing 3 comprises a rotation body 31, a dropper tube 300 disposed in the center, and a horizontal plate 32 connecting the rotation body 31 and the dropper tube 300. In the horizontal plate 32, there are at least two openings 33 for receiving the elastic arm portions 12. The number of openings 33 corresponds to the number of elastic arm portions 12. In one example, in the inner peripheral surface corresponding to the openings 32, the internal threads 35 are interrupted, so that the openings 33 are used as plugs to prevent the elastic arm portions 12 and thus the knob 1 from rotating in a circumferential direction relative to the pivoting housing 3.

[0058] [Fig.5] represents a cross-sectional view of the distributor 100 according to a embodiment of the present invention, the dispenser 100 being in the state corresponding to [Fig.lb], and [Fig.5] being taken in the YZ plane. [Fig.6] represents a cross-sectional view of the dispenser 100 according to an embodiment of the present invention, the dispenser 100 being in the state corresponding to [Fig.le], and [Fig.6] being taken in the YZ plane. [Fig.7] represents a semi-sectional perspective view of the container 1000 including the dispenser 100 according to an embodiment of the present invention, the dispenser 100 being in the state corresponding to [Fig.lb], and more clearly represents how the elastic component 2 is maintained in the compressed state.

[0059] In addition, in the inner peripheral surface of the rotating body 31 corresponding to the openings 32, a bearing portion 34 is formed. Once the knob 1 is inserted inside the rotating housing 3 by inserting the elastic arm portions 12 through the openings 33, the stop portion 15 of the knob 1 will pass the bearing portion 34 due to the elastic property of the elastic arm portions 12. Then, the stop portion 15 and the bearing portion 34 are used as stops to limit the axial movement of the knob 1 relative to the rotating housing 3, as shown in FIGS. 5 and 7.

[0060] In one example, the dispenser 100 also includes a flexible cap 4 that is attached to a free end of the dropper tube 300. Thus, the flexible cap 4 forms an inlet of the dropper tube 300. In one example, the dropper tube 300 is relatively rigid and the flexible cap 4 is made of a softer material so that the inlet of the dropper tube 300 is flexible. In one example, the flexible cap 4 is provided with a grooved ring 41 that allows it to bend when it contacts the bottom of the bottle 6, as shown in the diagram of [Fig.4b].

[0061] The elastic component 2 is disposed between the button 1 and the rotatable housing 3. The elastic component 2 is made of an elastic material and can be compressed and decompressed. In the example illustrated in [Fig. 2], the elastic component 2 is a plastic spring. In one example, the elastic component 2 is a corrugated plastic tube. The elastic component 2 has a chamber 22 and is disposed under the button 1. In particular, a closed upper end 21 of the elastic component 2 is connected to the button 1. The open bottom 23 of the elastic component 2 is sealed against the rotatable housing 3, as illustrated in [Fig. 7]. In one example, the dropper tube 300 is hermetically connected to the elastic component 2, and an internal passage 301 of the dropper tube 300 is fluidically connected to the chamber 22 of the elastic component 2.

[0062] The operation of the dispenser 100 is described below.

[0063] First, the distributor 100 is assembled. The elastic component 2 is arranged between the button 1 and the rotating housing 3. Then, by overcoming the resilient force of the elastic component 2, the button 1 is pushed inside the rotating housing 3 by inserting the elastic arm portions 12 through the openings 33. During the pushing of the button 1, the plug portion 15 of the button 1 will pass the bearing portion 34 due to the elastic property of the elastic arm portions 12. After releasing the button 1, the elastic component 2 snaps back or rebounds and lifts the button 1, as shown in Figures 1a and 1c. Here, as shown in Figures 1a and 1c, the elastic component 2 is in the decompressed state. In this way, the distributor 100 is formed as a single unit and the button 1 can only move axially relative to the rotating housing 3.

[0064] Next, the dispenser 100 is attached to the bottle 6 by the user rotating the rotating housing 3 clockwise. Generally, the dispenser 100 is fully engaged clockwise with the bottle 6 by means of the thread between the internal threads 35 of the rotating housing 3 and the external threads 51 on the neck 5 of the bottle 6. At this point, the dispenser 100 is fully engaged, as shown in Figures 1a and 4. In the fully engaged state, as shown in [Fig. 1a], the holding bar 141 is mounted with the ring 521 in a snap-fit ​​manner. In other words, the holding bar 141 is engaged with the ring 521 so that the button 1 is locked onto the neck 5 of the bottle 6.

[0065] Then, when the user starts to rotate the rotary housing 3 counterclockwise from the fully engaged state, as shown in [Fig.1a], the rotary housing 3 will gradually rotate axially away from the neck 5 of the bottle 6, but the knob 1 remains locked on the neck 5 of the bottle 6 by means of the interlocking between the holding bar 141 and the ring 521. In other words, during the counterclockwise rotation of the rotary housing 3, the knob 1 rotates together with the rotary housing 3, but the knob 1 does not move axially relative to the neck 5 of the bottle 6.Therefore, during the counterclockwise rotation of the rotary housing 3, the rotary housing 3 moves axially upwards and the button 1 does not move axially and, therefore the elastic component 2 is compressed, and a positive pressure is established in the chamber 22 of the elastic component 2, and the air or liquid present in the chamber 22 of the elastic component 2 is expelled or driven out.

[0066] After the counterclockwise rotation of the rotary housing 3, the rotary housing 3 is disengaged from the neck 5 of the bottle 6 by the disengagement between the internal threads 35 of the rotary housing 3 and the external threads 51 of the bottle 6, and the dispenser 100 is loosened from the neck 5 of the bottle 6, but at this stage, the button 1 continues to be locked on the neck 5 of the bottle 6 by means of the interlocking between the holding bar 141 and the ring 521, as shown in Figures 5 and 7. In this situation, the elastic component 2 is compressed to the maximum, and the largest volume of air or liquid present in the chamber 22 of the elastic component 2 will be expelled or driven out.

[0067] Then, a user will lift the rotating housing 3 with a slightly large force, and the holding bar 141 of the button 1 will slide back onto the ring 521 by the force, and the button 1 will thus no longer be locked onto the neck 5 of the bottle 6 and will leave them. At this point, the compressed elastic component 2 will recover or rebound, as shown in [Fig. 6], and during this process, as the elastic component 2 gradually expands, its chamber 22 expands and establishes a negative pressure therein and in the connected dropper tube 300. This negative pressure allows the contents, such as the cosmetic liquid, to be sucked from the bottle 6 into the dropper tube 300 through the inlet at the bottom of the dropper tube 300. In this way, the elastic component 2 acts as a pump to pump or suck the contents, to a certain extent.

[0068] After the expansion of the elastic component 2 is completed, the elastic component 2 returns to the fully decompressed state, and a fixed volume of cosmetic liquid is drawn into the dropper tube 300. At this point, as shown in the diagram of [Fig. 6], the dispenser 100 can be completely removed from the bottle 6, with the fixed volume of cosmetic liquid drawn into the dropper tube 300. Once the dispenser 100 is completely removed from the bottle 6, the user can press the button 1 to extrude the cosmetic liquid from the dropper tube 300 for use. At this point, the elastic component 2 is compressed, and the elastic component 2 acts as a pump to pump the contents, to a certain extent.

[0069] In this manner, a container 1000 comprising a dispenser 100 is provided with a simple structure to allow convenient access and accurate dispensing of the contents into the bottle.

[0070] In the above process, the user can hold the bottle 6 with one hand and rotate the rotating housing 3 of the dispenser 100 with the other hand to operate it. Alternatively, the user can use only the thumb and index finger to grasp and rotate the rotating housing 3 of the dispenser 100 while using the other fingers to grasp the bottle 6 in the palm of the hand to complete the operation. In this way, when the user rotates the rotating housing 3, there would be a direct transfer force to compress and open the dispenser 100.

[0071] In the above embodiments, the elastic component 2 is shown in the form of a corrugated plastic tube. However, it should be understood that the component elastic component can take other forms as long as it establishes a positive pressure in its chamber 22 when compressed and can push the button upward and establish a negative pressure in the chamber when recovered or decompressed. For example, the elastic component 2 can be a rubber bulb or a corrugated rubber bulb.

[0072] [Fig.8] shows a cross-sectional view of the container including the dispenser according to another embodiment of the present invention, the dispenser including a dropper for drawing the contents into the container via a dropper tube, and a flexible stopper being attached to a free end of the dropper tube.

[0073] In the example illustrated in [Fig.8], there is disclosed a container 1000' for loading the contents in liquid or gel form, the container 1000' comprising: a bottle 6' for containing the contents, the bottle 6' comprising a neck; and a dispenser 2' arranged on the neck for dispensing the contents from the bottle 6', the dispenser 2' comprising a dropper 21' for drawing the contents into the container via a dropper tube. In the example, the container 1000' further comprises a flexible cap 4' which is attached to a free end of the dropper tube 300', and preferably the flexible cap 4' has a grooved ring design. In this way, after disassembling the 2' dispenser, due to the extensibility of the 4' flexible cap, a user can extend the 300' dropper tube to allow the 4' flexible cap to reach the bottom of the 6' bottle.Therefore, the contents remaining at the bottom or on the inner walls of the bottle 6' can be recovered, because the dropper tube 300' can reach these areas of the bottle 6'. By means of the container comprising the flexible cap according to the embodiment of the present application, the product or contents which may be relatively expensive will be wasted less. In addition, the flexible cap can be easily adapted to existing dispensers or containers and does not require major modification of the dispensers or containers.

[0074] In the present application, the number of components in the container or dispenser according to the embodiments of the present invention is further reduced, and the structure is further simplified. Therefore, fewer components are used for durability. In addition, no metal spring is used and no butyl rubber is used. In other words, the container according to the embodiments of the present invention is made from plastic, and a lightweight concept is realized for the container according to the embodiments of the present invention.

[0075] In addition, the dispenser automatically loads a precise volume of cosmetic liquid during operation, which ensures a precise amount of cosmetic liquid with each use.

[0076] Aspects of the present disclosure have been described in detail with reference to the illustrated embodiments; however, those skilled in the art will recognize that numerous modifications may be made thereto without departing from the scope of the present disclosure. The present disclosure is not limited to the precise construction and compositions disclosed herein; all apparent modifications, changes, and variations of the foregoing descriptions are within the scope of the disclosure as defined by the appended claims. Furthermore, the present concepts expressly include all combinations and subcombinations of the foregoing elements and features. LIST OF DIGITAL REFERENCES
