Description

  A double storage structure in which a flow path having an action as a film check valve is formed in the inner region of the flowable packing material, and the filled flowable material can be poured out without being exposed to air. About the body.

  Conventionally, filling containers containing fluid fillers such as seasonings, beverages, foodstuffs, foods, cosmetics, painting materials, paints, lubricants, detergents, hair washing agents, disinfectants, drugs, etc. are classified into gel or Tube containers filled with highly viscous materials, solid containers made of metal, plastic, glass and earthenware filled with all fluid fillers including liquids and gases, and filled with liquids and cooking utensils It is roughly divided into bag-like containers.

  The above-mentioned tube containers are often used for gel-like or highly viscous paste products because of their good extrudability, and solid containers are characterized by high self-supporting, storage, convenience, robustness and safety. Furthermore, the bag-like container is light and inexpensive, and has the characteristics that the distribution cost in the manufacturing and distribution process can be reduced. There are different types.

  In recent years, there has been a strong demand for health and safety, and in the fields of food, seasonings, and lotions, the freshness and quality of the fluidized fillings that are filled is reduced by exposure to air and oxidation. Double containers have been proposed to prevent this.

  The basic structure of the double container that has been proposed in the past is that the inner container is filled with an air layer between the inner container and the outer container, and the outer container is squeezed from the outer direction to fill the inner container with fluid filling. The method of extruding an object indirectly via air pressure was adopted.

  However, the double container in which an air layer is interposed in the middle of such a dispensing container has a problem that the container itself is not self-supporting because the inner container and the outer container form a bag-shaped container body, respectively. The flexible inner container, the squeeze outer container, and the air layer interfere with each other, and the fluid filler filled in the inner container cannot be pushed out to the end by air pressure. The problem of extrudability that requires force, and because the air pressure is applied to the inner container on average due to the presence of an air layer between the inner container and the outer container, the locally remaining fluid filler is uniformly distributed. Many problems remained, such as the problem of being unable to pour out.

  In order to solve the above problems, various proposals have been conventionally made. For example, as a double container having a structure in which an air layer is interposed between an inner container and an outer container, and fluid filler filled in the inner container is squeezed by using the air pressure to indirectly push the outer container. `` Antioxidation container '' in which a thin food bag such as inflexible polyethylene or polypropylene is put in a conventional flexible mayonnaise container and an air hole is opened in the outer container (see Patent Document 1) Has been proposed and is a known technique.

  However, the proposal of the above “antioxidation container” is based on the indirect arrangement of the fluid filler filled in the soft and inflexible inner container with an air layer interposed between the flexible outer container. Because it is a structure that extrudes to the surface, the problem of being unable to pour out the highly viscous fluid filler that remains locally, and the need to push out more than necessary to indirectly extrude using air pressure The problem and the problem that the check valve effect of the fluid packing such as a low viscosity liquid is not provided cannot be solved.

  In addition, “a refillable bag storage container and a refill for refilling” by the present applicant composed of a filling bag body having a pouring cap portion and a squeeze holding device body having a squeeze property (flexibility). A “bag” (see Patent Document 2) has been proposed and is a known technique.

  However, the proposal of the above-mentioned “refillable bag storage container and refillable bag body” is that the outer container is a resin container having squeeze properties (flexibility). It is possible to pour out the remaining highly viscous material, but the structure is extruded indirectly using air pressure. The problem of preventing the backflow of the functional packing cannot be solved.

  In addition, a “double-structure squeeze holding tool” composed of an inner container provided with a cylindrical spout in a flexible bag and an outer container that covers the inner container and has a squeeze property (Patent Document) 4) has been proposed and is a known technique.

  However, the proposal of the above-mentioned “double squeeze squeezing tool” causes a rise in manufacturing cost due to the complicated structure of the lid, and the outer container has a squeeze property (flexibility). Therefore, the self-sustainability of the container itself can be ensured, but the problem that the extrusion force is required more than necessary cannot be solved because of the structure of extruding indirectly using the air pressure.

  On the other hand, as a structure that directly extrudes the fluid filler filled in the inner container by applying physical external pressure without interposing an air layer in the outer container, a self-supporting flexible liquid provided with an extraction port on the upper side A storage bag and a receiving part capable of allowing the self-supporting flexible liquid storage bag to stand on its own are provided, and a hole that can expose the extraction port is formed above the upper part of the frame part or the back part standing on the receiving part. A “liquid extractor for a self-supporting flexible liquid storage bag” (see Patent Document 4) is proposed, which is configured by a liquid extractor that is provided with a suitably shaped pressing body that is drilled at a predetermined position. It is a known technique.

  However, the proposal of the above-mentioned “liquid extractor for a self-supporting flexible liquid storage bag” is generally marketed because the extractor itself uses a bag body having a special structure (extraction port is sideways). Storage bags (filling containers) cannot be used, and the clamping part is exposed and lacks in safety and aesthetics. Furthermore, since one of the upright surfaces is at a right angle, the sense of stability of self-supporting is lacking. When extracting, it is necessary to attach an extraction pipe with a side cap that is inconvenient to use, which requires labor and complexity at the time of use and replacement.

  On the other hand, in the distribution stage, transportation costs have been reduced, and a stand-pack type liquid dispensing container has been developed in which the filling container can be disposable. For example, a product whose quality deteriorates due to oxidation when exposed to air is obtained by using the fluidity of the liquid, the plasticity of pipes and bags, and the external air pressure to cause the liquid itself to act as an air backflow prevention valve. “Antioxidation containers for liquid products” (see Patent Document 5) that can keep the area exposed to air to a minimum after opening and prolong the quality of the contents have been proposed (see Patent Document 5) and are well known.

  However, the proposal for the above-mentioned “antioxidant container for liquid products” is that a pipe with a length close to the bottom along one end is attached to the inside of the bag, and an anaerobic liquid is injected into the bag, and then the uppermost part is Since it is a bag-shaped container with a closed structure, it can be used as an anti-oxidation container for fluid containers with high viscosity, but as an anti-oxidation container for low-viscosity liquids, the squeeze action is temporarily applied while liquid is being dispensed. Since the structure does not have a check valve effect action that requires the cap to be closed in a state of being stopped, it is an antioxidant container with low practicality.

  In addition, the double pack packaging for drinking water that can maintain the fresh state of the initial filling for a long period without deteriorating the flavor of the poured liquid such as tea or coffee filled with the filter bag for containing the extraction material Non-self-supporting type, in which a bag and drinking water / extractable material co-filled packaging structure ”(see Patent Document 6) or a packaging bag formed by protruding a check nozzle outlet hole is filled with a liquid package In the packaging structure consisting of the fluid packing material and the self-supporting outer container used for storing and holding the same, the filled liquid package is not oxidized or contaminated, Furthermore, a “liquid-filled packaging structure” (see Patent Document 7) that does not deform or break even if it falls over during transportation or handling has been proposed and is a known technique.

  However, in the above-mentioned “double pack packaging bag for drinking water and packaging structure for drinking water / extractable material co-filling”, the soft laminated plastic film overlapped on one edge of the packaging bag main body made of the soft laminated film. A flat film-like non-return nozzle that projects a non-return function that prevents the intrusion of outside air into the bag by the close contact of the films when a liquid material is present in the pouring passage formed in It is a structure comprising a flexible packaging bag and a filter bag enclosing an extraction material such as teas, coffee, and fruits, which is stored in an airtight manner together with a liquid that is sealed and filled in the flexible packaging bag. On the other hand, in one “liquid-filled packaging structure”, a liquid plastic pouch having a non-returning function is provided in a soft plastic packaging bag. A non-self-supporting fluid packing material package that is packed in a hermetically sealed manner, and a cylindrical or rectangular tube-shaped self-supporting material made of hard plastic or paper for storing and holding the fluid packing material package And a liquid filling and packing structure comprising the outer container, and the outer container accommodates the liquid nozzle pouring hole of the fluid filling packing body in the upper end portion or the upper portion of the one side so as to be put in and out. Therefore, the following problems are pointed out because of the structure in which a pouring port is provided in a protruding manner.

(1) Since a planar film check valve is used, when a highly viscous fluid filler is poured out, there is a problem that the adhesion effect in the film check valve does not occur.
(2) Since the flow path of the film-like check valve protrudes to the outside and is short, air flows into the fluid filler packaging during use, so that the fluid filler is exposed to air and maintains freshness and oxidation. The problem that cannot be prevented.
(3) Since the adhesiveness is maintained by the film check valve, the adhesiveness cannot be maintained due to impact, contact, drying or wetness.
(4) When the product falls down, the film-like check valve opens and the fluid filling material starts to spill out.
(5) Since the flat film check valve protrudes to the outside, it is unsanitary in contact with other storage containers and food by being always exposed to the outside air and mounted. The problem.
(6) When air is mixed in the fluid filling package, air stays in the upper corner of the opposite side of the film check valve, and there is no way to discharge the air out of the fluid packing package. problem.
(7) Since the flow path of the film check valve that controls the amount of fluid filling is short, the fluid filler will be poured out at a stroke if the squeeze cover is gripped as much as possible. The problem of having to hold the double storage structure.
(8) Since the bottom area is small with respect to the height of the product, there is a problem that there is no stable independence.
(9) From the structure in which the fluid filling package is suspended in the squeeze cover, the fluid filling package is suspended in the squeeze cover, and the fluid filling is poured out in a stable state. The problem of not being able to.
As described above, the conventional double storage structure cannot solve many problems.

  The applicant of the present invention has a structure in which an air layer is interposed between the inner container and the outer container as described above, and the fluid filler filled in the inner container is indirectly pushed out by air pressure by a squeeze, and physical external pressure means. Focusing on the problems of pouring, self-supporting, simplicity, and hygiene in the double storage structure that extrudes the fluid filler, it is possible to solve these problems at once with a simple structure and means.
