Description

  The present invention relates to a foam ejection container that foams and discharges fluid contents (liquid, gel, etc.) by squeezing the body of the container.

For products that contain various liquid detergents such as shampoos, body soaps, hand soaps, facial cleansers, etc. and hair conditioners such as set lotions, the inside of the dispensing pump from the viewpoint of simplifying use by omitting the foaming action There are a number of products in which a foaming mechanism is incorporated and the contents are foamed immediately before pouring. As prior art in this regard, a bag means is disposed inside a flexible container. There is known a foam dispensing device that foams foamable liquid and air respectively held in a container through a porous member provided at the mouth of the container (see, for example, Patent Document 1).
Japanese Patent Publication No.59-271

  By the way, the conventional foam dispensing device has a problem that it becomes difficult to maintain a stable foamed state because the discharge amount of the contents varies depending on how the container is pushed during squeeze.

  The subject of this invention exists in the place which proposes the novel foam ejection container which can maintain the stable foaming state while enabling it to discharge | emit the content which has fluidity | liquidity as a fine foam.

The present invention has a container body having a squeezable body part and forming a filling space for the contents inside thereof, and a body which is installed inside the container body and which can be expanded and contracted along with the squeeze of the body part. An air-filling inner container having a portion, and a foam ejection container including a nozzle that is connected to each of the container body and the inner container, foams by mixing air into the contents, and discharges,
When the inner container is sandwiched between both sides of the pair of partition recesses in which the opposing inner walls are brought close to each other so as to contact each other, the inner wall is brought into contact with the inner wall. Two foam ejection containers are provided at positions where they do not come into contact with each other.

  In the foam ejection container having the above-described configuration, it is preferable that the inner walls brought close to each other function as a stopper that abuts upon squeezing and regulates the degree of pushing. Further, the wall surface of the body portion (the wall surface on the side provided with the inner wall that regulates the degree of pressing) positioned between the two sets of partition recesses can be used as the pressing portion during squeezing.

  In the squeeze, the inner wall of the container body is provided with two pairs of partitioning recesses before and after the inner container body is sandwiched on both sides and the opposing inner walls are brought into close contact with each other. It is possible to regulate the degree of pushing by contacting each other, and it is possible to always maintain a stable discharge amount. Further, since excessive force does not act on the inner container due to the restriction of the push-in degree, damage such as tearing can be avoided.

  The container main body exhibits a unique appearance shape due to the compartment recess, and thus can be easily distinguished from other containers.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
