Abstract

PROBLEM TO BE SOLVED: To improve a liquid container with a pump dispenser (hereinafter described as a container with a pump) for following three items: (1) To allow a pouch containing solution to be incorporated; (2) To allow the solution to be completely used up with no residue left; (3) To prevent entry of water into the pouch from outside.SOLUTION: A liquid container with a pump dispenser: comprises a pump part 5 assembled to a lid 2, and the lid 2 is detached to/attached from a threaded part 3 provided at a position having a sufficient size of a cross section in an upper part of a pouch 8 storage part. In addition, a projection 41 to maintain a shape of a bottom part of the pouch 8 and a position of the bottom part is provided on the bottom part of the pouch 8 storage position, as well as a fixture 61 having a hole or a pipe line 51 leading outside air into the pouch, while fixing a pouch open part to the pump 5. A suction pipe 7 long enough to touch the bottom of the pouch, which is fixed by the projection 41 to maintain its shape, is provided. The suction pipe 7 includes a tip which has an inverted crown shape, and which touches several positions on a circumference of the bottom part of the pouch to allow a solution to be suctioned up to a remaining amount of 1 to 2 mm depth, without being blocked.SELECTED DRAWING: Figure 3

Description

  The present invention relates to an improvement of a liquid container with a pump dispenser (hereinafter referred to as a container with a pump) that is widely used as a container for shampoos and detergents for home use and business use.

Viscous liquid products for household use such as shampoos, rinses and body soaps are almost 100% filled in pump containers. Containers with spray pumps are also used for low viscosity liquid products. When the contents of these products are used up, the contents are refilled and the contents are sealed in a flexible bag so that the container with the pump can be reused. Is a standing pouch (hereinafter referred to as a pouch).
Combining these two types of packaging with a pump or a container with a spray pump and a pouch and selling the same liquid is the main selling style of liquid products.

Kao Corporation November 10, 2015 News Release
Developed “Easy Pack” for refilling new containers that are both easy to use and environmentally friendly
http://www.kao.com/jp/corp_news/2015/20151110_001.html

 Containers with pumps are widely used for home and business use as containers for shampoos and detergents. An object of the present invention is to eliminate the troublesome refilling operation of the liquid agent and to reduce the liquid agent remaining in the pouch as much as possible.

  In order to solve the above-mentioned problems, the present invention is characterized in that a liquid agent storage container portion (hereinafter referred to as a pouch storage portion) of a pump-equipped container is provided with a protrusion that engages with a welded portion of a pouch bottom.

  According to the pump container of the present invention, it is freed from troublesome refilling of the liquid agent, and even if it is overturned for a short time, the liquid agent is not leaked into the pouch storage part, and the amount of the liquid agent remaining in the pouch is also minimized. It can be reduced, and hot water does not enter the pouch from the outside, and it can be used up cleanly.

An example of a standing pouch is shown in FIGS. The pouch 8 has a film formed in a bag shape and a “gusset” formed in the lower part thereof. A film is welded at the outer periphery to form a welded portion 81. The lower part of the left and right welded portions 83 is integrally welded with a film forming a gusset, and forms a four-sheet welded portion 82. FIGS. 3 to 4 show the first embodiment.
By maintaining the shape of the bottom of the pouch 8 as shown in FIGS. 1 and 2 as a self-supporting shape, and by providing a protrusion 41 that engages with the welded portions 81 and 82 of the pouch bottom at the center of the pouch storage unit 4, However, the pouch 8 is less likely to be crushed by its own weight, and the content liquid is less likely to leak. Further, the protrusion 41 is at a height almost in contact with the suction pipe tip 71 and sandwiches the film on the bottom of the pouch between the pipe tip 71. By contacting the suction pipe 7 at the deepest part of the bottom of the pouch, the liquid agent remaining in the pouch is minimized. Also, the protrusion 41 keeps the shape of the bottom of the pouch even when it falls, and maintains the sucking function from the deepest part when it returns to the upright position.
In addition, when a negative pressure is generated in the pouch 8 during use, the film forming the pouch becomes close or in close contact, and the liquid agent tends to remain due to capillary action, but the bottom shape of the pouch 8 is regulated by the protrusions 41. Can also be suppressed, and the residual liquid can be reduced as much as possible.
In order to prevent decompression in the container, it is desirable to introduce outside air by the volume of the discharged liquid agent, but in order to minimize the possibility of splashed water entering the pouch, the stem 11 slides above the pump container. The pump-container lid joint has a structure that shuts off water, while the lower part is provided with an air intake hole 42 at a position sufficiently lower than the pouch opening so as to actively take in outside air. A water drainage hole 43 is also provided to prevent sealing breakage, and even if splashed water enters from the lower air intake hole 42 so as to be discharged from the bottom, so that intruded water and condensation do not accumulate, Prevent intrusion water from touching the pouch opening even if it falls.
A fixing tool 6 is provided to fix the opening of the pouch at a high position. In order to prevent the pouch from collapsing as the liquid agent is discharged and the liquid agent remaining due to capillarity due to film adhesion, an external air inflow path is provided in the fixture 6 or the pump so as to introduce external air into the pouch. Either a backflow prevention valve or a long pipe 51 reaching the upper part of the pump is provided so that the liquid agent does not leak even when it falls.
The length of the suction pipe 7 is set to a length almost in contact with the center of the protrusion 41, and the tip of the pipe is horizontally cut and shaped like an inverted crown as shown in the example 71, so that there is almost no residue from the deep part of the pouch. A pipe that can be used.
FIG. 5 shows a modification of the protrusion 41. In the first embodiment, the protrusion 41 is formed in the shape of the bottom of the pouch storage portion 4, but it may be formed in a rib as shown in the figure.
FIG. 10 shows a modification of the rib shape. The projection 41 has a central portion that is cut into a linear V shape, thereby forming the same film on the bottom of the pouch. Thereby, the lowest area | region of a pouch bottom part becomes small, and the residue of a liquid agent can be decreased more.

It is a container of the usage form that occupies almost all market spread in some categories of household liquid detergents, and it is a theme that has been attempted many improvements both in the past and present, and is inevitably used.
