ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to a multi-functional dispenser, particularly to one convenient to be assembled and disassembled, and possible to economize producing time and cost.
Two conventional multi-functional dispensers respectively disclosed in the U.S. Pat. No. 6,065,477shown in FIG.
1
and U.S. Pat. No. 6,059,474 shown in
FIG. 2
, titled “MULTI-FUNCTIONAL FINGER ENAMEL DISPENSER”, are made with the same technique and have the same feature.
As shown in
FIG. 2
, the multi-functional finger enamel dispenser includes a resilient hollow tube
10
and a brush pencil
20
. The brush pencil
20
is composed of a brush pencil body
21
, a brush rod
22
and a pencil cap
23
. The brush pencil body
21
has opposite ends communicating with each other and is provided at the bottom with an open hole
211
with an inner threaded portion
212
to be threadably fitted with an outer threaded portion
13
of the hollow tube
10
. Further, the brush pencil body
21
has its inner intermediate portion shrunken into a shoulder
214
, and is disposed inside with a conical pencil head
24
having a projecting ring
241
on top resting on the shoulder
214
, with the pencil tube
242
of the pencil head
24
extending out of the brush pencil body
21
through the open hole
213
on top.
In addition, a connect member with female threads
215
is provided between the inner threaded portion
212
and the shoulder
214
of the brush pencil body
21
, and a connect base
221
with male threads
227
is fitted protruding on top of the brush rod
22
. The outer diameter of the upper connect portion
222
of the connect base
221
is equal to the inner diameter of the opening
243
of the pencil head
24
, with the connect base
221
fixed with the connect member of the brush pencil body
21
. The connect base
221
further has a stuffing ring
223
shrunken at the bottom and having an outer diameter equal to the inner diameter of the opening
12
of the resilient hollow tube
10
. Then, the brush rod
22
has a plurality of solvent guiding holes
224
bored along the rod wall at a proper location under its connect base
221
, with the solvent guiding holes opened through upward to make the top of the brush rod
22
formed into an open hole
225
and having a brush hair
226
fixed on the bottom.
However, the conventional finger enamel dispenser described above has the following disadvantages.
1. High producing time and cost: The conventional device is made of at least five essential components including a brush pencil body, a pencil head, a pencil tube, a connect base and a brush rod, being complicated to combine the components with one another.
2. Not easy to be assembled and disassembled: The combination among its components is complicated, so it is not easy to be disassembled for cleaning in case the pencil head, the pencil tube or the connect base should be blocked, and it is difficult to be assembled after cleaning.
3. Unsafe in using: The pencil head tightly pushed by the brush rod is fixed inside the brush pencil body, and the pencil tube at the end portion of the pencil head is in a fixed condition, therefore the pencil tube is liable to damage the surface of a finger nail in case of an excessive force in paining it.
SUMMARY OF THE INVENTION
The objective of the invention is to offer a multi-functional dispenser easy to be assembled and disassembled and possible to economize producing time and cost.
The multi-functional dispenser of the invention includes a container body, a pencil head bolder, a brush rod and a top cover. The feature is that the hollow brush rod head of the brush rod has its outer circumferential edge formed into a projecting rim, and the hollow cavity of the pencil head holder has a bottom connect opening formed with an engage groove so as to let the brush rod and the pencil head holder engaging with each other directly. Besides, the pencil head holder and its top solvent outlet tube are formed integral, thus, preventing the solvent outlet tube from moving biasly to ensure safety in using, and lowering producing time and cost.
