Abstract

(57) [Summary] (Modified) [Purpose] To provide a two-liquid mixing and dispensing device in which two liquids are completely mixed. [Structure] Two manual dispensing devices 1 equipped with pump means
0, an adapter 20 that connects the discharge stems of the two manual dispensing devices 10 and integrates them into one discharge passage, and a discharge means 30 attached to the adapter 20 in combination to store two liquids in one external container 40. In the mixing device, a plurality of stationary blades are provided in the liquid flow path of the adapter 20 so that the two liquids are completely mixed in the adapter 20.

Description

[Detailed description of the device] [Industrial applications]

 The present invention relates to an improved dispensing device that mixes and administers two liquids for use. More specifically, the present invention relates to improvement of a compound dispenser in which two pump type dispensers are arranged side by side and liquids discharged from each are mixed and administered.

[0002]

[Prior art and its problems]

 Various composite containers for mixing and administering a so-called two-part composition on the spot have long been proposed, and some have been put into practical use. Typically, in Japanese Utility Model Publication No. Sho 52-37853, two pressure accumulating and dispensing dispensers (so-called aerosol containers) are lined up and held, and both discharge ports are connected by an inverted T-shaped outlet pipe. Apparatus is disclosed. This device naturally suffers from various problems of accumulator filling technology (fluorocarbon propellant, disposal of used container, danger, etc.), and the container must be cylindrical because of pressure resistance. When two are placed side by side, the spatial loss is large. Such products have little or no commercial success due to environmental considerations. It has also been proposed by the applicant of the present utility model to make the above-mentioned composite dispensing device for two-part composition non-aerosol (Actual Kaihei 4-). One problem with the two-liquid mixing and dispensing device is that the mixing of the two discharged liquids is not always perfect. Therefore, a further mixing operation may be required after discharging. The present invention seeks to solve this problem.

[Device configuration]

 The device of the present invention comprises two manual dispensing devices equipped with pumping means, an adapter for connecting the discharging stems of the two manual dispensing devices and integrating them into one discharging passage, and a discharging device mounted on the adapter. A two-liquid mixing and dispensing device comprising a means and an external container for accommodating them, wherein an adapter comprises an outer part having a stem part and an inner part fitted into the outer part to form a liquid passage, and the outer part is It is a long lid having a discharge stem in the center, and the inner part has a receptacle for closely accommodating the stem of each manual dispensing device and a hole forming a liquid passage at the position of the stem, and It is characterized in that it is fitted to a lid-like portion of an outer portion having an extension portion having a plurality of stirring vanes extending into the stem to form a liquid passage therebetween. Since the device of the present invention can be easily manufactured by those skilled in the art, it is not necessary to describe materials, working methods and the like.

[Specific disclosure of device]

 The present invention will now be described in detail with respect to one specific example with reference to the drawings. 1 is a partial cross-sectional view as seen from the front, showing the structure of one embodiment of the device of the present invention, FIG. 2 is a similar drawing as seen from the side, and FIG. 3 is a partial cross-sectional view as seen from the upper side. 4 is a plan view of the inner portion of the adapter, FIG. 5 is its front view, FIG. 6 is its side view, FIG. 7 is its bottom view, and FIG. 8 is the assembled adapter. FIG. This device comprises two manual dispensing devices 10 with known pump means and an adapter 20 which connects the discharging stems (14) of the two manual dispensing devices into one discharging passage. It comprises an ejecting means 30 mounted on an adapter and an external container 40 for accommodating them.

The manual dispensing device 10 comprises a container 11, a pump 12 having a suction pipe and a pump stem 14, and a lid 13 for mounting and fixing the same on the container. These structures are well known to those skilled in the art and need not be described in detail. It is desirable for the space-economic condition that the container of the manual dispenser is not cylindrical but the part that contacts the adjacent manual dispenser is flat. The adapter 20 comprises an outer portion 21 having a stem portion and an inner portion 22 fitted in the outer portion to form a liquid passage. The outer part 21 is a long lid-shaped body having a chimney-shaped stem 21 in the center, which is shaped like a stadium for athletics. As shown in FIGS. 4-7, the inner portion has a receiving portion 22b for closely accommodating the stem of each manual dispensing container and a hole 22a forming a liquid passage at the position of the stem of the manual dispensing device, and A member having a projecting portion 22c extending upward from the central portion thereof, penetrating into the passage portion of the stem of the outer portion and agitating the two liquids passing through the passage, the portion having a protruding portion 22c. It is fitted into the lid-like portion of the outer portion 21 so as to penetrate the stem, and forms a liquid passage 23 therebetween. As a result, the liquid discharged from one manual dispenser and the liquid discharged from the other manual dispenser are well mixed by the time they reach the outlet of the stem.

A jet button (discharging means) 30 is attached to the stem 21 of the adapter 20. It may employ any known ejection means. Thus, the two manual dispensing devices are joined by an adapter, resulting in a joined assembly with ejection means. The combined body is housed in the outer container 40. The outer container 40 is composed of a body portion 41 and a lid portion 42 in the illustrated embodiment, and is adapted to be fitted and coupled 43. The lid portion is provided with an opening so that the stem 21 of the adapter and the discharging means 30 are exposed. Depending on the design, this opening can also be a stem-only passage. Usually, the outer container is provided with a protective lid 50.

In the illustrated embodiment, the lid portion is provided with a rib 42a for pressing the shoulder of the container of the manual dispensing device, and the cushion means 44 is adopted, but these are not essential constituent elements. This is a design problem that can be appropriately adopted. Also, the outer container is composed of two parts, a body part and a lid part, but it is not limited to this and may be composed of three parts. The two manual dispensers contain different liquids. Depressing the ejection means (button) depresses the pump stems of the two manual dispensers, but the elastic recovery means raises it again. By operating the pump in this way, the two liquids are pumped up, not mixed in the adapter, but completely mixed and discharged in the discharging means (button).

[0008]

[Effect of the device]

 According to the present invention, there is provided a two-liquid mixing container which does not rely on the accumulator filling method, which is problematic. It can be easily manufactured by adopting a mixing adapter that is easy to manufacture. By making one side of the container of the manual dispenser flat, the whole structure can be made compact and the mixing of the two liquids can be done completely by the adapter.
