Description
Background of the Invention
1. Field of the Invention
The instant invention relates generally to receptacles and more specifically it relates to an improved liquid dispenser.
2. Description of the Prior Art
Numerous receptacles have been provided in prior art that are adapted to hold and carry various types of materials, so that the materials can be utilized therefrom. While these units may be suitable for the particular purpose to which they address, they would not be as suitable for the purposes of the present invention as heretofore described.
Summary of the Invention
A primary object of the present invention is to provide an improved liquid dispenser that will overcome the shortcomings of the prior art devices.
Another object is to provide an improved liquid dispenser that consists of a container for holding liquid, an apparatus extending upwardly from the container for dispensing the liquid and a cover which fits over the apparatus to allow the liquid to exit therefrom.
An additional object is to provide an improved liquid dispenser in which the container is in the shape of an animal body, while the cover is in the shape of a matching animal head, so as to make the dispenser pleasing to the eye.
A further object is to provide an improved liquid dispenser that is simple and easy to use.
A still further object is to provide an improved liquid dispenser that is economical in cost to manufacture.
Further objects of the invention will appear as the description proceeds.
To the accomplishment of the above and related objects, this invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that changes may be made in the specific construction illustrated and described within the scope of the appended claims.

Detailed Description of the Preferred Embodiments
Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, the Figures illustrate an improved liquid dispenser 12 which consists of a container 14 for holding liquid 16 therein. A mechanism 18 extending into and upwardly from the container 14 is for dispensing the liquid 16 out of the container 14, so that the liquid 16 can be used in convenient amounts. A cover 20 engages with the liquid dispensing mechanism 18 extending upwardly from the container 14 to allow the liquid 16 to exit from the cover 20.
The container 14 is in the shape of an animal body 22, while the cover 20 is in the shape of an animal head 24. The container 14 is fabricated out of a plastic material 26 and the cover 20 is also fabricated out of a plastic material 26.
The container 20 contains an externally threaded neck 28. The liquid dispensing mechanism 18 contains an internally threaded cap 30, to engage with the externally threaded neck 28 on the container 20. The liquid dispensing mechanism further includes a dip tube 32 below the internally threaded cap 30, which extends into the liquid 16 within the container 14. A device 34 is for extracting some of the liquid 16 up through the dip tube 32 and out of the cover 20.
The liquid extracting device 34, as shown in the first embodiment in FIG. 1 and the third embodiment in FIGS. 5, 7, 9 and consists of an accumulator 36 between the internally threaded cap 30 and the dip tube 32. A piston 38 extends upwardly from the accumulator 36 through the internally threaded cap 30. A saddle head 40 having a spout 42 is also provided. The saddle head 40 is fluidly connected to the position 38 and is mounted within the cover 20 with the spout 42 extending through the cover 20. When the cover is depressed downwardly, some of the liquid 16 will exit through the spout 42. A distal free end 44 of the spout 42 is located on the cover 20 approximate at a mouth 46 of the animal shaped head 24.
The liquid extracting device 34, shown in the second embodiment in FIG. 3, includes a squeeze tube 48 extending upwardly from the internally threaded cap 30 and is fluidly connected to the dip tube 32. The squeeze tube 48 has a spout 50 extending through the cover 20. When the cover 20 is compressed together at the spout 50 as shown in FIG. 2, some of the liquid 16 will exit through the spout 50. A distal free end 52 of the spout 50 is located on the cover 20 approximate at a nose 54 of the animal shaped head 24.
In the third embodiment as best seen in FIG. 6, the container 14 includes an annular sleeve 56, formed about the externally threaded neck 28, so as to form a recess thereabout. The third embodiment as best seen in FIG. 8, further includes a flexible collar 58 for the cover 20. A structure 60 is for attaching the flexible collar 58 about a lower end of the cover 20. This forms a seal about the recessed externally threaded neck 28 of the container 14 and the internally threaded cap 30 of the liquid dispensing mechanism 18, when the cover 20 is depressed downwardly.
The flexible collar attaching structure 60 consists of the cover 20 having an annular groove 62 about its lower end. The flexible collar 58 has an annular tongue 64 formed about an upper end, so that the annular tongue 64 can engage with the annular groove 62.
As shown in FIGS. 9, 10 and 11, the saddle head 40 in the third embodiment is internally mounted to the cover 20. An L-shaped frame 66 is formed within the cover 20, so that a corner of the L-shaped frame 66 will contact an upper rear portion of the saddle head 40 opposite fro the spout 42. A fastener 68 secures the upper rear portion of the saddle head 40 to the cover of the L-shaped frame 66. The fastener 68 is a mounting screw 70, which extends through the upper rear portion of the saddle head 40 and into the corner of the L-shaped frame 66.
