Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a refill pouch, and more
particularly to a pouch being able to assemble with a pump head for
dispensing directly and prevent the deformed pouch from obstructing
a through hole.
[0003] 2. Description of Related Art
[0004] A conventional refill package for fluid materials comprises
a container having a main body portion to be filled with fluid. The
container is formed of rigid but deformable light-weight material.
A handle-pouring spout for the container is formed integrally
therewith of the material and is generally U-shaped. The
handle-pouring spout has an intermediate elongated portion which is
parallel to the container. End portions are formed with continuous
through openings. The through openings are defined in the end
portions for communicating with the interior of the container.
Accordingly, a transverse weak section is formed on the
intermediate portion in a single plane along the length of the
intermediate portion adjacent one end portion. The transverse weak
section enables the intermediate portion to be severed from the one
end portion and to cooperate with the other of the end portions to
function as a pouring spout for the contents of the container.
[0005] The conventional refill package for fluid materials is
designed to refill bottles for cosmetic products such as shower
gel, shampoo, etc. However, the refill package for fluid materials
would be threw away after the fluid in the refill package is poured
into the bottles. This would increase the amount of waste materials
and causes an environmental pollution.
[0006] The present invention has arisen to mitigate and/or obviate
the disadvantages of the conventional refill package for fluid
materials.
SUMMARY OF THE INVENTION
[0007] The main objective of the present invention is to provide an
improved refill pouch.
[0008] To achieve the objective, the refill pouch includes a head
member and a pouch member connected with the head member. The head
member has a threaded portion and a disc portion formed thereon.
The threaded portion has one end connected with a top side of the
disc portion. The threaded portion adapts to be threadedly
connected with a pump head. The disc portion of the head member
extends downwardly and outwardly from a center thereof. The head
member has a through hole defined therein and extending through the
threaded portion and the disc portion.
[0009] A top of the pouch member is securely connected with a
bottom side of the disc portion of the head member opposite to the
threaded portion by a connection means chosen from high-frequency
sealing or hot-press laminating. The pouch member has an opening
defined in the top thereof and located corresponding to the through
hole for communicating with the through hole. The opening of the
pouch member has a diameter relatively smaller than that of the
disc portion of the head member. The pouch member has a flat
bottom. The pouch member has a neck portion annularly formed on a
periphery thereof. The neck portion centrally locates between the
top and the bottom of the pouch member. The pouch member has a wall
thickness gradually decreasing from the top to the bottom thereof.
The pouch member has a maximum wall thickness being in a range from
1.1 to 3 times a minimum wall thickness. The pouch member gradually
decreases from the top to the neck portion and gradually increases
from the neck portion to the bottom in size.
[0010] Further benefits and advantages of the present invention
will become apparent after a careful reading of the detailed
description with appropriate reference to the accompanying
drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0015] Referring to the drawings and initially to FIGS. 1-3, a
refill pouch 1 in accordance with the present invention comprises a
head member 2 and a pouch member 3 connected with the head member
2. The pouch member 3 adapts to contain and store a liquid
substance (not shown). The head member 2 has a threaded portion 21
and a disc portion 22 formed thereon. The threaded portion 21 has
one end connected with a center of a top side of the disc portion
22 and axially extends from the disc portion 22. The threaded
portion 21 adapts to be threadedly connected with a pump head 10.
The disc portion 22 of the head member 2 annularly extends
downwardly and outwardly from the center of the disc portion 22.
The head member 2 has a through hole 23 axially defined therein and
extending through the threaded portion 21 and the disc portion 22.
The through hole 23 communicates with the pump head 10.
[0016] A top of the pouch member 3 is securely connected with a
bottom side of the disc portion 22 of the head member 2 opposite to
the threaded portion 21 by a connection means chosen from
high-frequency sealing or hot-press laminating. The pouch member 3
has an opening 31 defined in the top thereof and located
corresponding to the through hole 23 for communicating with the
through hole 23. Accordingly the liquid substance in the pouch
member 3 is able to flow into the through hole 23 via the opening
31. The opening 31 of the pouch member 3 has a diameter relatively
smaller than that of the disc portion 22 of the head member 2, such
that the disc portion 22 sealingly covers the top of the pouch
member 3 to prevent leakage of the liquid substance through the
opening 31. The pouch member 3 has a flat bottom 32.
[0017] The pouch member 3 has a neck portion 33 annularly formed on
a periphery thereof. The neck portion 33 centrally locates between
the top and the bottom of the pouch member 3. The pouch member 3
has a wall thickness gradually decreasing from the top to the
bottom 32 thereof. And a maximum wall thickness of the pouch member
3 is in a range from 1.1 to 3 times a minimum wall thickness. The
pouch member 3 gradually decreases from the top to the neck portion
33 and gradually increases from the neck portion 33 to the bottom
32 in size.
[0018] In a preferred embodiment, the maximum wall thickness of the
pouch member 3 is 1.5 times the minimum wall thickness. When the
pump head 10 generates a vacuum sucking force to suck the liquid
substance from the pouch member 3 into the though hole 23 of the
head member 2, the liquid substance is sequentially guided out from
the pump head 10. As shown in FIG. 4, the pouch member 3 would not
have an intense deformation. And the through hole 23 would not be
obstructed by the deformed pouch member 3.
[0019] Because the pump head 10 is detachably connected with the
threaded portion 21 of the head member 2, the refill pouch 1 is
able to be used directly. It is different from the prior art which
is used to refills a container and treated as waste. The refill
pouch 1 in accordance with the present invention is designed to
have an energy-saving effect and sufficient environmental
protection. Moreover, the through hole 23 of the head member 2 is
able to be sealed by a cover or a seal film (not shown) so as to
prevent leakage of the liquid substance from the through hole 23
during periods of storage and shipment.
[0020] Although the invention has been explained in relation to its
preferred embodiment, it is to be understood that many other
possible modifications and variations can be made without departing
from the spirit and scope of the invention as hereinafter
claimed.
