Description

  The present invention relates to a packaging container, and in particular, by pressing the packaging container by hand, fluid such as water or a viscous material filled in the packaging container can be easily pushed out of the packaging container. The present invention relates to a packaging container in which a fluid does not flow out in a normal state in a sealed or near-sealed form so that outside air does not enter the filling portion of the packaging container.

  As an example of a packaging container in which cosmetics are used as a fluid to which the present invention is typically applied, bags, tubes and the like are used as containers, and these containers are filled with cosmetics. It is sold in a state, and when used, the cap is removed and a predetermined amount is taken out to the palm and used.

  Of the above-mentioned jars, for example, those having a fairly high viscosity, such as a latex, are usually those in which a wide-mouth jar is simply closed with a screw cap. For items with low viscosity such as low-viscosity or lotion, attach an inner lid with a small hole to the mouth and fix it so that the lotion does not flow out at once when the cap is removed. It is normal.

  However, in the case of additive-free cosmetics to which no preservatives or the like are added, there is a problem that the cosmetic ingredients may be oxidized or deteriorated when used for a long period of time. However, even if the product is aseptically processed at the time of manufacture, the cosmetics often contain components suitable for bacterial growth such as fats and oils, so there is a possibility that airborne bacteria may propagate. There is a risk of cosmetic decay.

  For this purpose, as in Patent Document 1, it is connected and fixed to an easily deformable bag-shaped inner container filled with a fluid such as cosmetics and one end opened, and the open portion of the one end of the inner container. Alternatively, the plug body mounting portion provided integrally, the plug body mounted on the plug body mounting section and partitioning the open portion at one end of the inner container from the outside air, and the inside of the inner container and the outside air are sealed in an airtight state in a natural state. When the inside of the inner container becomes positive pressure with respect to the outside air, it is elastically deformed and operates in a check valve type so as to allow the fluid filled in the inside to flow out. A packaging container comprising: a valve body provided in the stopper body; and an outer container connected and fixed to the stopper body mounting part so as to enclose the inner container with a gap. The outer container is rigid enough to be self-supporting in a natural state, and the outer container A packaging container for cosmetics or the like is invented, which has elasticity that can be easily deformed inward when it is held and is provided with an air circulation hole that can be closed with a finger. It was.

  According to this, the container in which unused cosmetics and the like remain can be reliably sealed from the outside air, and a container from which an appropriate amount of cosmetics can be easily taken out at the time of use has a small number of parts. In addition, it can be provided at a low cost as a simple structure.

  In addition, it does not require a special operation for those who use cosmetics, and the above-described operation can be realized simply.

  Further, the contents to be filled are not limited to cosmetics, and the same effect can be obtained also as containers for various seasonings or pharmaceuticals such as eye drops, quasi drugs and the like.

Furthermore, as in Patent Document 2, a flexible tubular body having openings at both ends, a spout connected to one of the openings of the tubular body, and comprising a shoulder and a hollow tubular neck And a lid part that covers and seals the spout from above, and the lid part has an opening and closing part that is opened by deforming the cylindrical body part to increase the internal pressure. Containers are also known, which allows the contents to be taken out easily with one hand.

  In this case, in the upright state as shown in FIG. 10, the fluid 105 is accumulated at the bottom, and in order to discharge the fluid 105, it is necessary to hold and press in the inverted state.

  On the other hand, as shown in FIG. 7, a container body 71 having a rigidity that allows it to be self-supporting in a natural state and an elasticity that can be easily deformed inward when held and pressed, and the opening of the container body 71 The container 72 that is fixedly connected to or integrally provided with the opening part of the container body 71 that separates the open air from the outside except the extraction port 73 and the extraction port 73 of the plug body 72 that is connected and fixed or provided integrally. In addition, a packaging container is known that includes a fluid 76 including a cylindrical body 74 that extends to the vicinity of the bottom of the container body 71.

  In this case, as shown in FIG. 8, the internal pressure of the packaging container is increased by holding and pressing the container main body 81, and the fluid 86 is discharged from the extraction port 83 of the stopper 82 via the cylindrical body 84. Become.

  Here, when the pressurization is stopped as shown in FIG. 9, the shape of the container body 91 is restored and the restoring force 97 works, the pressure is reduced, the suction force 98 works on the extraction port 93, and not only the fluid 96 but also the air is reversed. The fluid 99 becomes a fluid 99 and flows backward into the container main body 91 via the extraction port 93, the cylindrical body 94, and the opening 95, and a part of the fluid 99 enters the air bubble 100.

In the following, an embodiment of the present invention will be described with reference to FIG. 1 to FIG. 3, which have a rigidity that can be held in a natural state and an elasticity that can be easily deformed inward when gripped and pressed. A container body, a plug body that is connected and fixed to the open part of the container body, or a container body that separates the open part of the container body from outside air except for the extraction port; and the inside of the container body and the outside air in a natural state Acts like a check valve to seal and allow the fluid filled inside the container body to flow out to the outside of the container body when it becomes positive pressure against the outside air A package comprising: a valve body that is fixedly connected to or integrally provided with the stopper body, and a cylindrical body that is connected and fixed to the extraction port of the stopper body or integrally provided and extends to the vicinity of the bottom of the container body. This will be described in the case of a container.

  As shown in FIG. 1, the packaging container of the present invention includes a container body 11, a plug body 12, a valve body 13, and a tubular body 14.

  The container body 11 typically has a rigidity that allows it to be self-supporting in a natural state and an elasticity that can be easily deformed inward when gripped and pressed.

  For example, various external shapes such as a round shape with a cylindrical shape or a box shape with rounded sides, and a shape with a narrowed shape so as to be easily held at the center can be employed.

  Moreover, what was comprised as a container which enabled the assembly | attachment of the stopper to the one end part is used preferably. In this case, the structure that allows the plug body to be assembled is generally a screw as shown in FIG. 1, but may be a structure that allows other plug bodies such as a lock mechanism to be assembled, or may be integrated with the plug body. Good.

  Moreover, the material can be formed using, for example, various types of polyethylene such as low density polyethylene resin, medium density polyethylene resin, high density polyethylene resin, linear low density polyethylene resin, polyolefin resin such as polypropylene, and plastic material. .

  Moreover, it can also be comprised with the double container which consists of a relatively rigid outer container and a soft inner container.

  The plug 12 is assembled and fixed to the container body and sealed from the outside air, and the opening part of the container body connected to and fixed to the opening part of the container body or provided integrally therewith is an extraction port 14 from the outside air. It is structured to be divided by other than.

  Moreover, the material can be formed using, for example, various types of polyethylene such as low density polyethylene resin, medium density polyethylene resin, high density polyethylene resin, linear low density polyethylene resin, polyolefin resin such as polypropylene, and plastic material. .

  Moreover, it can also be comprised with the double container which consists of a relatively rigid outer container and a soft inner container.

  Further, the valve body 13 hermetically seals the inside of the container body 11 and the outside air in a natural state, and elastically deforms into the inside of the container body 11 when the inside of the container body 11 becomes positive pressure with respect to the outside air. It has a structure that is connected and fixed to the stopper that operates in a check valve type so as to allow the filled fluid to flow out of the container body.

  For example, a plate-like elastic body that constitutes at least a part of the member that constitutes the plug body is formed with a slit extending in the shape of a cross or the like, thereby forming a lip that can be bent and deformed in the thickness direction. Thus, a valve structure can be exemplified.

An elastic body having a duck beak-like shape (referred to as “duck bill”) and having a slit formed at the tip thereof can also be used, and in this case, a reverse valve action can be obtained with certainty. With the simple structure of these slit-type and duckbill-type valves, cosmetics filled in the inner container can be discharged (discharged) to the outside by applying external pressure, but air enters the inside from the outside. This can constitute a check valve that prevents this, and the discharge amount can be adjusted by the thickness of the slit portion, the size of the slit, and the like.

  The material can be composed of various synthetic rubbers, for example, elastic bodies such as butadiene styrene rubber, butyl rubber, neoprene, and silicone rubber.

  As shown in FIG. 1, the valve body 13 is locked to the plug body 12 by utilizing the elasticity of the valve body 13, but the present invention is not limited to this. For example, a screw is provided at the extraction port of the plug body. Fixing by using a fixing ring or the like that is inserted, fixing by a screw method, or the like can be employed.

  The cylindrical body 15 is in the shape of a pipe or the like, and is connected and fixed to the extraction port 14 at the upper end portion thereof, or provided integrally therewith, and the lower end portion thereof needs to extend to the vicinity of the bottom of the container body 11. The lower end may or may not contact the bottom. However, since the lower end is closed when it is in complete contact with the bottom, the tubular body should be slightly longer than the length up to the bottom so that the fluid can enter and exit at the lower end of the tubular body. The bottom and lower end portions of the bottom body and the lower end portion are configured such that the cylindrical body is curved and slanted at the bottom to form the opening 16, or conversely, the tubular body is slightly shorter than the length to the bottom. Various methods can be used, such as creating a gap between them and securing the flow path of the fluid, or securing the flow path by cutting the bottom end of the cylindrical body obliquely.

  Moreover, the material can be formed using, for example, various types of polyethylene such as low density polyethylene resin, medium density polyethylene resin, high density polyethylene resin, linear low density polyethylene resin, polyolefin resin such as polypropylene, and plastic material. .

  The extraction port 14 is provided in the plug body 12, and is a path through which the fluid 18 moves from the inside of the packaging container to the outside, and is generally a cylindrical through-hole. In general, the valve body 13 is slightly opened at the upper end portion and is directly connected to the cylindrical body 15 at the lower end portion.

The notch 19 of the container body 11 which is an internal / external circulation air passage normally eliminates the internal / external pressure difference by allowing the inside and outside of the packaging container to vent through the notch 19, and normally prevents the inside / outside ventilation and grips the packaging container. Thus, the inside of the packaging container can be pressurized by gripping and pressing so as to dent inward, so that air is discharged to the outside of the packaging container accordingly. Conversely, the gripping and pressing operation for gripping and grasping the packaging container is released, that is, the inside of the packaging container can be decompressed by returning to the outside, and air is accordingly introduced from the outside of the packaging container accordingly. is there.
This is generally formed by providing an extremely small air path between the container body 11 and the plug body 12. For example, as shown in FIG. 4, a small notch 42 is provided at the upper end of the container body 41. 5, a notch 52 is provided in the plug body 51 as shown in FIG. 5, a structure that weakens the seal of the screw portion of the plug body to the container body, or a screw portion of the container body 61 as shown in FIG. Various means can be adopted, such as the construction of a corresponding air inflow hole 62.

  In such a packaging container, as shown in FIG. 2, the container body 21 is deformed by the gripping and pressing 28, thereby increasing the internal pressure of the packaging container, the fluid 26 becomes the cylindrical body 25, and the extraction port 23 of the plug body 22. The pressure increases and the valve body 23 is opened, so that the fluid 26 can be used as the discharged liquid 27. In this case, some air is exhausted 30 through a notch 29 which is an internal / external circulation air passage.

Further, when the gripping pressure is released as shown in FIG. 3, the restoring force 37 works, and the container body 31 returns to the original shape. In this case, the valve body 33 has a check effect, and neither fluid nor air returns to the inside of the packaging container through the extraction port 34 or the cylindrical body 35 from this portion. In this case, since the packaging container is in a depressurized state, air is gradually ingested 39 through the notch 38 which is an internal / external circulation air passage.
