Description

  The present invention relates to a pouch with a stopper having a filling portion spout composed of a filling portion spout and its cap, and a dispensing portion spout composed of a spouting portion spout and its cap.

Mouthed pouches are widely used in the field of food such as jelly drinks, soft drinks and kneaded products, and toiletries. Furthermore, in recent years, it has been actively used as a substitute for glass bottles and plastic bottles in the medical field. In this case, a method is generally adopted in which a tube is connected to a spout to administer the contents. However, if the contents are nutrients or liquid foods, pouches that have only a spout and a cap for the spout and its cap for use with other drugs and water when used are filled with spouts. It is necessary to use it as a mouth or to cut a part of the pouch and add other medicines and water from the cutting mouth, which makes the work complicated and has various problems in terms of hygiene. In order to improve these problems, a pouch having two plugs, a filling port plug and a dispensing port plug, has been proposed (for example, refer to Patent Document 1).

  However, the proposed pouch with a plug has a content even when the pouring part plug is detached from the spout and the cap is opened, the cap is again attached to the spout and the spout is resealed. It was made up of things that leaked out and had many disadvantages.

  The object of the present invention is a pouch with a stopper provided with a filling part plug and a pouring part plug, a function to protect the spout for the pouring part before opening and the contents even if it is remounted after opening It is an object of the present invention to provide a pouch with a spout provided with a spout part cap comprising a spout part cap having both functions of preventing leakage of goods and a spout part for a spout part used therefor.

The invention according to claim 1 of the present invention is composed of two laminated materials for side walls and one laminated material for a bottom part, and is one of the upper sides of a pouch having a self-supporting property whose peripheral edge is sealed. A pouch with a plug having a filling part spout composed of a spout for filling part and a cap for filling part at the corner of the container, and a spout part spout composed of a spout for dispensing part and a cap for the dispensing part at the other corner The spout for spouting portion is installed by being heat-sealed to the laminated material through a pair of mounting portions projecting outward and connected, and the tip portion of the spout for spouting portion is a top surface portion. The cutting is provided in the tip portion around the top surface portion, and a male screw portion is provided in a portion adjacent to the mounting portion of the outer peripheral side wall portion of the spout portion spout, The cap for the pouring part is the first of the protective cap part at both ends. It has an opening and a second opening of the reseal cap portion, and is formed of an integrally molded product in which the protection cap portion and the reseal cap portion are joined at a top surface portion. A female threaded portion is provided on the inner periphery of the hollow body comprising the side wall portion that surrounds the portion and adjacent to the first opening, and the female threaded portion is formed on the male side of the outer peripheral side wall of the spout for spout. The extraction portion cap is mounted on the extraction portion spout by being screwed into the screw portion, and the reseal cap portion is a hollow formed of a side wall portion surrounding the top surface portion. A female screw part is provided on the inner periphery of the body near one of the second openings, and the female screw part is screwed into the male screw part on the outer peripheral side wall of the spout for spout. And a protrusion protruding toward the second opening on the top surface portion And when the reseal cap portion side is mounted toward the spout for spout, the spout is opened by cutting the cutting cut of the spout for spout And is configured to close and seal the spout, and the protrusion is surrounded and protected by the side wall portion of the reseal cap until it is inserted into the spout. The pouch with a mouth plug is characterized by being exposed to the outside .

  The pouch with a stopper according to the present invention is composed of two laminated materials for side walls and one laminated material for a bottom part, and is one corner of the upper side of the pouch having a self-supporting property whose peripheral edge is sealed. In the pouch with a plug having a filling portion spout composed of a spout for filling portion and a cap for filling portion, and having a spout portion plug composed of a spout for dispensing portion and a cap for dispensing portion in the other corner, An opening is provided at one end of the pouch body side of a hollow body of a predetermined shape having a side wall portion around the outer periphery of the spout for the extraction portion, a top surface portion is provided at the other end, and protrudes outward on the outer surface of the opening portion side. The mounting portion is continuously provided, a male screw portion is provided on the outer periphery close to the mounting portion, and a cutting notch for providing a spout is provided on the outer periphery close to the top surface portion. Protrusion cap has a side wall on the entire outer periphery A spout for the pouring portion is provided when a female screw portion is provided on the inner periphery adjacent to the opening provided at one end of the hollow body of a predetermined shape, and the female screw portion is screwed into the male screw portion of the spout for spout portion A protective cap portion comprising a top surface portion at a position covering the upper end, and a female screw portion on the inner periphery adjacent to an opening portion provided at one end of a hollow body having a predetermined shape having a side wall portion on the entire outer periphery. Provided at the other end is provided with a top surface portion having a protruding portion projecting toward the opening for sealing by inserting into a spout provided in the spout for the spouting portion at the time of re-sealing, Re-seal cap part that has a length that allows the female screw part to be screwed into the male thread part of the spout for the spout part and is integrally molded so as to have openings at both ends, and is protected The cap side is attached to the spout for spout Therefore, if the base material layer and sealant layer of the laminated material are heat resistant, high-temperature and high-pressure sterilization becomes possible, and those filled with the contents are spouted out during storage. The cap is securely protected by the protective cap part of the cap for the cap, and when it is resealed after being opened once, the spout is sealed by the protrusion of the reseal cap part of the cap for the pouring part, and the female screw part is male. Since it is screwed into the screw part, the contents do not leak out. Accordingly, it is most suitable as a pouch for packaging of nutrients, liquid foods and the like, particularly in the packaging field that requires a filling port plug and a dispensing port plug.

  The pouch with a spigot of the present invention will be described below along the embodiments. FIG. 4 is a side sectional view showing an embodiment of a laminated material used in the pouch with a stopper according to the present invention.
