COMPLETE SPECIFICATION PETTY PATENT Invention Title: DEVICE FOR OBTAINING CONTENTS IN A CONTAINER AT DESIRED QUANTITY Name of Applicant: LIEN-FANG CHU The following statement is a full description of this invention, including the best method of performing it known to me/us: DEVICE FOR OBTAINING CONTENTS IN A CONTAINER AT DESIRED QUANTITY FIELD OF THE INVENTION [0001] The present invention relates to a device connected to a bottle or container and is able to obtain the contents in the container at desired quantity without opening the container.

BACKGROUND OF THE INVENTION [00021 Conventional bottles or containers generally include an opening through which the contents in the container is accessed or taken. A cap is removably connected to the opening of the container so as to prevent dust from entering the container. When taking out the contents, the user removes the cap from the container and tilts the container to pour the contents out, or the user uses a spoon to get the contents. However, for some contents, such as powders and tiny particles which are required to be kept from moisture, the frequent the cap is removed, the more possibilities the contents are contaminated.

SUMMARY OF THE INVENTION [00031 In accordance with one aspect of the present invention, there is provided a container assembly and comprises a container having an opening with which a first cap is mounted. The first cap has a first aperture and a protrusion extends from a top surface of the first cap. A second cap is rotatably mounted to the first cap and has a slot for the protrusion being movably received therein. A second aperture is defined through the second cap. A tube has a first open end rotatably engaged with the second aperture and an end member is rotatably connected to a second open end of the tube.

[00041 The primary object of the present invention is to provide a container assembly wherein thile contents in the container can be obtained at desired quantity without opening the cap.

[00051 The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

BRIEF DESCRIPTION OF THE DRAWINGS S0 [0006] Fig. 1 is a perspective view to show the container assembly of the present invention; [0007] Fig. 2 is an exploded view to show the container assembly of the present invention; [0008] Fig. 3 is an illustrative view to show a close position and an open position of the container assembly when rotating the second cap; [00091 Fig. 4 is a top plan view to show the second cap is rotated by pushing the tube connected to the second cap, and [00101 Fig. 5 is a perspective view to show the container assembly of the present invention connected with a milk powder container.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT [00111 Referring to Figs. 1, 2 and 4, the container assembly of the present invention comprises a container 3 having an opening 30 and a first cap 11 is mounted to the opening The first cap 1 I has a first aperture 16 and a protrusion 15 extends from a top surface of the first cap I 1. A plurality of ridges 14 extend from an outer periphery of the first cap 11 and perform as threads.

[00121 A second cap 13 is rotatably mounted to the first cap I I by receiving the ridges 14 on the first cap I I in grooves 17 defined in an inner side of the second cap 13. The second cap 13 has a slot 18 defined therethrough and the protrusion 15 is movably received in the slot 18. A second aperture 19 is defined through the second cap 13 and can be moved to a position in communication with the first aperture 16. A plate 12 is received between the first cap 11 and the second cap 13, and performs as a seal which minimizes gaps between the first cap 11 and the second cap 13 when the second cap 13 is rotatable relative 19 to the first cap 11. The plate 12 has a first hole 120 for the protrusion 15 extending therethrough, and a second hole 121 which is located in alignment with the first aperture 16.

A neck 190 extends from a top surface of the second cap 13 and encloses the second aperture 19. The neck 190 has two L-shaped slots 191 which open to a top edge of the neck 190.

[0013] An L-shaped tube 21 has a first open end rotatably engaged with the neck 190 and two pins 23 respectively extend radially outward from the first end of the tube 21 so that the two pins 23 are movably engaged with the two L-shaped slots 191. A boss 192 extends from an inner periphery of a horizontal section of each of the two L-shaped slots.

191 so that when the pin 23 moves over the boss 192, the pin 23 is positioned in stable as shown in Fig. 4. The tube 21 has first threads 25 defined on an outer periphery thereof and scales 26 marked on the tube 21. An end member 22 is rotatably connected to a second open end 24 of the tube 21, wherein the second open end 24 is an enlarged end so as to prevent the end member 22 from disengaging from the second open end 24. The end member 22 has second threads 27 which are threadedly connected to the first threads 25. A polygonal piece 28 is connected to a distal end of the end member 22 so that when rotating the polygonal piece 28, the end member 22 can be moved toward or away from the second open end 24 of the tube 2 1.

[00141 When pivoting the tube 21 counter clockwise to rotate the second cap 13 rotate relative to the first cap 11 which is fixed, the position of the slot 18 is moved and the protrusion 15 is shifted from a close position to an open position as shown in Fig. 3. In the open position, the second aperture 19 is rotated to communicate with the first aperture 16, and the contents such as powder can be poured into the tube 21 and the end member 22.

The volume of the powder filled in the end member 22 and the tube 21 can be decided by adjusting the end member 22 as shown in Fig. 4. The second cap 13 is then rotated clockwise to remove the second aperture 19 away from the first aperture 16 so that the first aperture 16 is closed by the second cap 13. Therefore, the powder in the tube 21 and the S end member 22 is the desired volume.

[0015] Figure 5 shows that the container assembly can be used with different type of containers such as a milk powder container 31.

[0016] While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
