BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for containing a fluid such as a gas, a liquid or a paste, and more specifically, to the outside air when the fluid is poured out from the container or thereafter. The present invention relates to a container for preventing entry into the inside of the container, a spout of the container, and a lid used for the container.

2. Description of the Related Art Currently, products such as foods, cosmetics and pharmaceuticals are manufactured so as to suppress the oxidation of products by adding antioxidants (preservatives) or the like in order to maintain the quality as long as possible. There are many things. Thus, manufacturing a product by adding an antioxidant (preservative) is one of the effective means for extending the life of the product, increasing the value of the product, and contributing to the development of industry. However, on the other hand, in recent years, there has been an increasing demand for using foods and the like as natural as possible without adding such an antioxidant (preservative).

In order to suppress the oxidation of foods and the like without adding an antioxidant (preservative) or the like, for example, a container having a function of preventing the outside air from entering the inside of the container is manufactured. It is possible to take a means of enclosing food products and the like in a container for use, and as a specific conventional example thereof, Japanese Patent Application Laid-Open No. 10-29647 (1 of conventional example) is disclosed. The container proposed in the first example of the related art has a substantially liquid-like fluid as a content, and is generated when an external pressing force is applied to deform the container and the container is about to return to its original shape. A small restoring force is used to operate a check valve provided in the outflow passage of the contents to prevent outside air from entering the inside of the container.

The outline of this container will be described below. This container includes a container body filled with contents, a mouth stopper attached to the container body, a pouring stopper having a spout for pouring out the contents of the container to the outside, and the mouth stopper. It was mainly composed of a check valve installed in the. The main structure of this container was as follows. That is, the mouth stopper is attached to the container body, the pouring stopper is connected to the mouth stopper, the container body is pressed to deform the container body, and the contents are provided to the mouth stopper by this pressing. The check valve closing the flow passage is pushed open to flow out, and the content is poured out of the container from the pouring outlet.

When the pressing is released, the container body deformed as described above tries to return to the original shape and a small restoring force is generated, and the check valve which has been spread by the contents is restored by this restoring force. It is sucked into the inside of the container body to close the flow passage. The container is capable of preventing outside air from entering the inside of the container body when the check valve closes the flow passage.

[0006]

According to such a structure of the container, when the check valve closes the flow passage, the contents inside the container body with respect to the check valve do not come into contact with the outside air. It is like this. However, the contents on the pouring side of the check valve, that is, the contents left in the space from the check valve to the pouring port are not always in contact with the outside air, There is a problem in that the contents are oxidized and deteriorated in quality when they come into contact with the outside air, and it is necessary to use the deteriorated quality every time the container is used.

Further, as described above, the restoring force generated in the container is used to operate the check valve. However, in a container which produces a large (strong) restoring force, the check valve is attached to the container. Even if the container body has a large (strong) restoring force, a large (strong) suction force into the container body is generated in the container body, and the container body is filled with the outside air to the contents once poured to the outside. Since it is sucked into the inside, this container can be applied only to those that generate a small restoring force, and it becomes less versatile.

Furthermore, if the restoring force generated in the container is utilized as described above, the restoring force of the container varies depending on the material used for the container. Therefore, the strength of the check valve depends on the restoring force. There was a problem that it became difficult to set. Therefore, the present invention relates to a container having a container body containing a fluid such as gas, liquid or paste, and a discharge part having an outflow hole for discharging the fluid to the outside. A first object of the present invention is to provide a container that can prevent (block) outside air from entering the inside of the container regardless of the restoring force generated in the container when discharged. In addition to the above-mentioned first purpose,
The second purpose is to provide a highly versatile container and a stopper for the container that does not allow outside air to enter the inside of the container. In addition to the first and second purposes, the inside of the container is used every time it is used. A third object of the present invention is to provide a container capable of discharging the fluid whose quality is maintained in 1., a spout of the container, and a lid used for this container.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. The container 1 shown in FIG. 14 is of a type generally used for food-related products, for example, seasonings such as mayonnaise and ketchup. The container 1 includes a container body 2 for containing a fluid (food such as a gas, a liquid, a paste, and containing medicines, favorite foods, etc., which may be simply referred to as contents hereinafter) and a container body 2. Discharge unit 3 for discharging the stored fluid to the outside of the container, and this discharge unit 3
It is mainly composed of an elastic coating 7 covering the above.

The container body 2 is formed by forming a resin material such as polyethylene, polypropylene, PET, nylon, TPE, etc. into a bag shape, and the discharge part 3 is formed by protruding from the mouth portion of the bag shape. A discharge port 8 for discharging the contents of the container body 2 to the outside of the container 1 is formed at the tip of the projected discharge unit 3.
The container 1 having such a configuration can be obtained by pushing the body of the container 1 with a hand (finger) along the direction of the arrow indicated by the symbol A in FIG. 14 or twisting the body of the container 1. The pressing force for discharging the contents from the discharge port 8 can be transmitted to the contents.

FIG. 1 is an enlarged view of the discharge part 3 and shows a first embodiment of the container according to the present invention. The discharge part 3 shown in FIG. 1 has a protrusion (spout or spout) formed by projecting from a bag-shaped mouth portion of the container body 2 and the contents flowing out of the container 1. And an outflow hole 6 for letting it flow. The outflow hole 6 is formed near the tip of the protrusion in the protrusion so that the contents of the container 1 can flow out from the outflow hole 6.

An elastic film 7 for covering the outflow hole 6 is covered on the protrusion. This elastic coating 7 is made in consideration of physical properties such as viscosity and particle size of the contents of the container 1, chemical properties such as PH, and appearance, economy, usability, etc.
Can be freely selected from rubber, resin, etc. for molding. For example,
NR, SBR, BR, NBR, CR, EPM, EPD
M, IR, IIR, FKM, VMQ, U, T, CO, A
Rubber CM, SBS, SIBS, SEBS, SIS, SE composed of at least one of CM
PS, SEEPS, TPO, TPU, TPEE, TPA
E, TPVC, 1,2-polybutadiene thermoplastic elastomer, fluorine thermoplastic elastomer, and the like,
It is also possible to use a complex thereof or the like.

In the first embodiment, the elastic coating 7 has a tubular shape so as to cover substantially the entire projection, and the elastic coating 7 is covered on the projection 5. In this case, the elastic coating 7 is stretched due to the shape of the protrusion, that is, the shape of the ejection portion 3. The elastic coating 7 does not have to be stretched by the protrusion when it is put on the protrusion, but has a tube diameter such that it is stretched by the protrusion when it is put on the protrusion. Is desirable. By being stretched, an elastic force is always generated in the elastic film 7, and the elastic film 7 always tightens the protrusion portion by this elastic force, so that the adhesion with the outflow hole 6 provided in the protrusion portion is maintained. It can be made large and can prevent backflow of discharged contents and outside air.

In order to flow out the contents of the container 1 to the outside of the container 1, the contents flow out from the outflow hole 6 by overcoming the elastic force of the elastic coating 7 that is in close contact with the outflow hole 6. It is necessary to apply such pressing force to the container 1 (contents). When the pressing force is applied, the contents of the container 1 flow out from the outflow hole 6 and further elastic force is generated in the elastic film 7, and when the pressing force applied to the contents is released, this elastic force is It works so as to close the outflow hole 6, whereby it is possible to prevent (block) outside air from entering the inside of the container 1 through the outflow hole 6.

Although it has been described above that the elastic coating 7 has a tubular shape, in the first embodiment, when the elastic coating 7 is covered on the protrusion, the tip of the protrusion is covered. The end portion of the elastic coating 7 located on the side, that is, the portion corresponding to the mouth of the tube is a discharge port 8 for discharging the content of the container 1 flowing out from the outflow hole 6 to the outside of the container 1. . As shown in FIG. 1, the protrusion has a cylindrical shape having an outer shape such that the bottoms having the larger diameters are joined to each other in two cones having substantially the same shape. The end face of the tip is closed.

Therefore, the protrusion has a tapered shape from a portion corresponding to the edge of the bottom surface (hereinafter, simply referred to as edge 10) toward the tip of the protrusion. Here, the direction from the outflow hole 6 to the discharge port 8 is indicated by the arrow B, but this direction will be referred to as the discharge direction B hereinafter. By making the discharge portion 3 (projection portion) have the tapered shape as described above, the content (fluid) flowing out from the outflow hole 6 can easily flow toward the discharge port 8. More specifically, in the portion from the outflow hole 6 to the ejection port 8 (portion indicated by reference numeral 18) in the ejection portion 3, the content (fluid) flowing out from the outflow hole 6 flows toward the ejection port 8. It is shaped to make it easier.

Hereinafter, such a portion (content (fluid))
The portion for flowing in the discharge direction B) is called the discharge guide portion 18. On the other hand, in the discharge portion 3, the portion from the outflow hole 6 to the edge 10 (the portion indicated by reference numeral 19) is widened from the outflow hole 6 to the edge 10, so that the content (fluid body) flowing out from the outflow hole 6 is removed. The discharge direction B is made to be difficult to flow in the opposite direction. Hereinafter, such a portion (a portion that prevents the content (fluid) from flowing in the direction opposite to the discharge direction B) will flow through the content (fluid) in the direction opposite to the discharge direction B. Backflow prevention unit 19 for preventing
Call.

By thus providing the discharge part 3 with the discharge guide part 18 and the backflow prevention part 19 in the discharge part, the contents flowing out from the outflow hole 6 are allowed to flow in one direction (discharge direction B). If the flow is controlled, the contents flowing out from the outflow hole 6 can be discharged without waste. Further, a plurality of the outflow holes 6 are formed in this tapered portion as elongated holes along the taper of this portion, and as described above, the shape of the protruding portion is changed from the edge 10 toward the tip of this protruding portion.
