Since the conventional pouring device is used for a bag-in-box type container, an annular basket for holding the container in the box is provided on the outer periphery of the spout. In the case of a bag-in-box type container, a pouring device is provided near the bottom, and a locking portion is provided between the tip of the spout cylindrical spout and the inner surface of the cap so that the cap does not come out due to the pressure of the contents. Provided.
However, when this type of dispensing device is used for a general spout container, the inner pressure as in a bag-in-box is not applied to the cap, so that no annular hook or locking portion is formed at or near the tip of the spout. In addition, since the cap is a flexible material such as rubber having flexibility, when the cap is attached to the cylindrical spout, there is a possibility that the spout will be blocked by being pushed too much.

  The present invention has been made in view of the above circumstances, and even a general spout container that is not particularly assumed to be fitted with such a cap is excessively pushed into the cylindrical spout of the container. It is an object of the present invention to provide a cap that can be easily attached without a cap and a container with a cap including the cap.

In order to solve the above-mentioned problem, the present invention is a cap that is attached by being pushed into a cylindrical spout of a container, and is connected to the membrane-shaped portion that closes the opening of the cylindrical spout, and the membrane-shaped portion A cylindrical portion provided outside the cylindrical spout, a push-in position restricting portion that abuts against a front end surface of the cylindrical spout and restricts a push position of the cap into the cylindrical spout, and the cylinder A spout portion for pouring out the contents flowing out from the gap between the tubular spout and the membrane-shaped portion, and the distance from the tip surface of the tubular spout to the spout portion is the tubular spout There is provided a cap characterized in that the cap is larger than the distance from the front end surface to the push-in position restricting portion.
It is preferable that the said spout part protrudes in the direction perpendicular | vertical to the said cylindrical spout from the inner side of the said cylindrical spout to the outer side.
Moreover, this invention provides the container with a cap by which said cap is attached to the cylindrical spout of a container.
The container is preferably composed of a spout having a cylindrical spout and a flexible pouch.

  According to the present invention, the push-in position restricting portion that contacts the tip end surface of the cylindrical spout of the container and restricts the push-in position of the cap with respect to the cylindrical spout is lower than the spout portion (the front end surface of the tubular spout The distance between the cap and the cylindrical outlet of the container is not wrinkled, or the cap is pushed too far into the cylindrical outlet of the container, The cap outlet can be easily attached without being blocked.

It is sectional drawing which shows the example of 1 aspect which attached the cap of this invention to the spout. It is a perspective view which shows one example of a form of the cap of this invention. It is sectional drawing along the spout part of the cap shown in FIG. FIG. 3 is a projected view of the cap shown in FIG. 2, (a) is a plan view, (b) is a left side view showing the spout port side, (c) is a front view, and (d) is the side opposite to the spout port. (E) is a bottom view. It is sectional drawing which shows the example of a position of operation which pours out the contents from the container which attached the cap of this invention to the spout.

The present invention will be described below based on preferred embodiments with reference to the drawings.
The spout 25 shown in FIG. 1 is sealed by a bag-like container such as a pouch 26 as shown in FIG. The spout 25 includes a cylindrical spout 20 that protrudes outward in the container. The cylindrical spout 20 has a flow path for the contents defined by the inner surface 24 thereof. The flow path is opened by the opening 21 a of the distal end surface 21 of the cylindrical spout 20.

  A cap 10 that closes the opening 21a is attached to the cylindrical spout 20 of the spout 25 by pressing. The cap 10 includes a membrane portion 11 that closes the opening 21 a of the cylindrical spout 20, a tubular portion 12 that is connected to the membrane portion 11 and provided outside the tubular spout 20, and a tubular spout Contents that flow out from the gap 18 between the cylindrical spout 20 and the film-shaped portion 11, the pushing position restricting portion 13 that abuts against the front end surface 21 of the outlet 20 and restricts the pushing position of the cap 10 into the cylindrical spout 20. And a spout part 14 for pouring out the water.

The film-shaped part 11 is formed of an elastic material such as a soft elastic resin or rubber, and closes the opening 21a by closely contacting the entire periphery of the opening 21a from the tip surface 21 to the inner surface 24 of the cylindrical spout 20. Further, the membrane portion 11 can be easily elastically deformed. As shown in FIG. 5, when the operation portion 16 is tilted away from the spout portion 14, the contents are passed through the flow path 14 a inside the spout portion 14. Can be poured out. The shape of the operation unit 16 is not particularly limited, and an arbitrary shape such as a rod shape, a ring shape, a bowl shape, or a flat shape can be used.
In order to transmit a force for deforming the membrane portion 11 when the operation portion 16 is operated, a connection reinforcing portion 17 such as a plate shape or a rod shape is provided between the operation portion 16 and the membrane portion 11. The connection reinforcing portion 17 is preferably formed at least at a position from the operation portion 16 toward the spout portion 14.
Between the outer surface 22 of the cylindrical spout 20 and the inner surface of the cylindrical part 12 of the cap 10, it is made smooth so that cylindrical surfaces can slide, and unevenness, such as a locking part, is not provided. .

In the cap 10 of this embodiment, the distance from the distal end surface 21 of the cylindrical spout 20 to the spout portion 14 is larger than the distance from the distal end surface 21 of the cylindrical spout 20 to the pushing position restricting portion 13. In other words, the spout portion 14 is formed to be higher than the push-in position restricting portion 13. As shown in FIG. 4 (e), the push-in position restricting portion 13 is provided around the opening 21a, for example, by a half or more, and a part on the spout portion 14 side is opened, so that the internal flow path 14a of the spout portion 14 is opened. It becomes the communication part 15 connected with. Since the push-in position restricting portion 13 is continuously provided in a portion other than the communication portion 15, the contents do not enter into an extra portion other than the communication portion 15. Further, since the gap between the front end surface 21 and the push-in position restricting portion 13 is narrow, the contents are less likely to stay inside the cap 10. For this reason, it is possible to prevent the contents staying in the cap from spilling unexpectedly.
The distal end surface 21 of the cylindrical spout 20 may be a flat surface, and the push-in position restricting portion 13 of the cap 10 can be an arc-shaped plane parallel to the distal end surface 21.

As shown in FIG. 5, the cap-equipped container 28 in which the cap 10 of the present embodiment is attached to the spout 25 has a cylindrical spout 20 sealed by the membrane portion 11 of the cap 10 so that it can be stored and repeated for a certain period of time. In addition to being able to be used, it is easier to open and close compared to a screw-type cap, and it is not necessary to remove the cap 10 when taking out the contents. Since the operation part 16 protrudes above the cap 10, the operation part 16 can also be operated with the finger of the same hand, holding the container 28 with a cap with one hand.
The spout portion 14 projects from the inner side to the outer side of the cylindrical spout 20 in a direction (leftward in FIG. 1) perpendicular to the cylindrical spout 20 (up and down direction in FIG. 1), and the flow of the contents spreads. It is preferable because it is easy to pour out.

  The spout 25 can be molded, for example, by injection molding using a thermoplastic resin. Examples of the thermoplastic resin include polyolefins such as polyethylene and polypropylene. A screw 23 is provided on the outer surface 22 of the cylindrical spout 20. The screw 23 is generally provided for fixing a screwed lid (not shown) for sealing the container 27 when the container containing the contents is distributed or sold.

The lid provided on the container 27 before the cap 10 is attached is ring-shaped below a threaded portion (for example, the female screw of the lid screwed with the screw 23 which is a male screw) for tamper-proof (preventing tampering). It may have a portion that breaks. In this case, as shown in FIG. 1, it can be confirmed that the ring-shaped fracture portion 30 remains around the cylindrical spout 20 and has been opened. Further, the cap 10 of the present embodiment is configured such that the push-in position restricting portion 13 abuts against the front end surface 21 of the cylindrical spout 20 to prevent excessive push-in, and even if the user is not familiar with general consumers, Easy to install and easy to use.
In addition, the lower end surface 12b of the cylindrical portion 12 of the cap 10 does not need to contact the annular flange 29 provided on the outer periphery of the cylindrical spout 20, and the cap 10 does not contact the ring-shaped fracture portion 30. Even if the broken portion 30 remains on the flange 29, the cap 10 can be reliably attached to the distal end portion of the cylindrical spout 20 above the ring-shaped broken portion 30.

The cap 10 of this embodiment can be attached by being pushed in without using the screw 23, and a recess 12 a that avoids the screw 23 is formed inside the cylindrical portion 12. Thereby, the cap 10 can be attached to an arbitrary spout 25 without depending on the pitch or height of the screw 23. The cylindrical portion 12 has a concave portion 12a because its diameter increases from the distal end surface 21 side of the cylindrical spout 20 toward the base portion side of the spout (from the top to the bottom in FIG. 1). Is difficult to be caught by the screw 23 and can be easily pushed.
When an inner seal (film or the like) is adhered to the distal end surface 21 of the cylindrical spout 20 in the original container, the cap 10 is attached after the inner seal is removed. Even if there is adhesive residue or the like of the inner seal on the front end surface 21, there is no hindrance to the attachment of the cap 10. Moreover, the cap 10 of this embodiment can be attached to the cylindrical spout 20 that does not have the screw 23 on the outer surface 22 or the cylindrical spout 20 that has the female screw formed on the inner surface 24.
Cap 10 can be attached even if there is no locking part or annular ridge at or near the distal end of cylindrical spout 20, and can be applied to the cylindrical spout of various containers as long as the diameter is the same. High versatility. By manufacturing several types with different diameters, various products can be handled, inventory management becomes easy, and costs can be reduced.

  Above the recess 12a, the distal end portion of the cylindrical spout 20 is tightly sandwiched between the membrane portion 11 and the tubular portion 12, so that the tubular spout 20 is not provided with a locking portion such as a protrusion. However, it becomes difficult to remove the cap 10. It is preferable that the cap 10 of this embodiment is provided on the upper part of the container 27 having self-supporting properties and is attached to a position where the pressure of the contents is not applied from the inside of the cap 10. When the container 27 is self-supported, the cylindrical spout 20 may be in a horizontal (horizontal) direction, but is preferably upward or obliquely upward.

As mentioned above, although this invention has been demonstrated based on suitable embodiment, this invention is not limited to the above-mentioned example, Various modifications are possible in the range which does not deviate from the summary of this invention.
The film-shaped part 11, the cylindrical part 12, the operation part 16 and the like can be combined as separate bodies, respectively, and can also be formed as an integrally molded product as shown in FIG. When the cap 10 is an integrally molded product, an elastic material such as a soft elastic resin or rubber that can obtain the necessary film-like portion 11 from the viewpoint of elastic deformation and adhesion is preferable. In the case of a separate body, it is possible to mold from a hard resin other than the film-like portion 11.

When the cylindrical spout 20 is cylindrical, it is preferable that the cylindrical part 12 of the cap 10 is also cylindrical. The tip surface 21 and the inner surface 24 or the outer surface 22 may be chamfered or rounded, but a locking portion such as a conventional bag-in-box spout is not necessary. In the drawing shown in FIG. 4, the shape of the cap 10 is symmetric with respect to the spout portion 14, and the rear view (the upper surface of FIG. 4A) is symmetric with the front view of FIG. Appear in
The spout portion 14 may have a shape protruding upward (in the upward direction in FIG. 1) parallel to the tubular spout 20 depending on the contents and use.

  The pouch 26 is a flexible container composed of one or a plurality of flexible films. Although the form of the pouch is not particularly limited, it can be selected from various forms such as a three-sided bag, a four-sided bag, a pillow-type packaging bag having a back adhesive, a standing pouch, a gusset bag, and a square bottom bag. .

  The film constituting the pouch 26 is not particularly limited, but a laminate having a sealant on at least one side thereof, for example, polyethylene (PE), polypropylene (PP), ethylene-vinyl acetate copolymer (EVA), cyclic A polyolefin resin layer such as polyolefin is used as the innermost layer (sealant), and a stretched film such as a biaxially stretched nylon film, biaxially stretched polyethylene terephthalate film, or biaxially stretched polypropylene film is used as the base material. A laminate film having a polymer, a vapor deposition layer of metal or an inorganic compound (for example, ceramic such as silica), or a metal foil such as aluminum foil as an intermediate layer can be used. These films are flexible and foldable, are convenient for transportation and storage when empty, are not bulky after use, and are excellent in volume reduction and disposal. In order to suppress deterioration and deterioration of the contents, it is preferable to use a film having low permeability to oxygen and water vapor. From this viewpoint, a film including a layer made of a metal or an inorganic compound (ceramic or the like) is preferable.

The sealant of the film is preferably provided at least on the inner surface side of the pouch 26. In this case, the spout 25 is attached to one end edge of the pouch 26 by welding the thermoplastic resin on the outer surface of the spout 25 and the sealant of the pouch 26. It becomes possible to attach to the horizontal edge of FIG.
The spout 25 has a shape in which a portion (base portion) attached to the opening portion of the pouch 26 extends to the left and right along one edge of the pouch 26, so that the welding to the edge of the opening portion of the pouch 26 is facilitated. ing.

Although the dimensions of the container such as a pouch are not particularly limited, for example, the height is about 100 to 500 mm, the width is about 70 to 300 mm, and the filling amount is about 100 to 5000 cm ³ .
The content is not particularly limited, but for example, in addition to liquids and liquids, it is also applicable to low fluidity content such as powders, granules, or viscous bodies. Specific examples include foods, beverages, lotions, pharmaceuticals, seasonings, syrups, seasonings, cosmetics, detergents, grains, fertilizers, adhesives, inks, chemicals, organic solvents, oils, creams, various solutions. Alternatively, powdery or granular materials such as synthetic resins can be used. The powder or granules may be dried or contain liquid. Examples of viscous materials include jelly, highly viscous oils, and liquid adhesives.
