Description

  The present invention relates to a sealed package. More specifically, the present invention is usefully used for a single-use package containing a small amount of liquid or fluid such as soy sauce, dressing or shampoo, or a refill package containing a large amount of these liquid or fluid. It can relate to a sealed package.

  For example, as in the case of a small size single use package shown in FIG. 1, this type of conventional sealed package 1 is configured in a bag shape having an arbitrary planar shape such as a quadrangle. More specifically, the sealed package 1 has a bag-like configuration in which a pair of resin films 2 are bonded to each other at a seal portion 3 (portion indicated by hatching in FIG. 1). Contained a liquid or fluid. Further, a spout 5 that is a thin liquid passage that is communicated with the bag-like portion 4 and sealed at the tip is provided from an arbitrary portion of the bag-like portion 4. The slit 6 is provided in the lateral direction.

  When the sealed package 1 is used (when the contents are squeezed out), the slit 6 is opened and the spout 5 is opened, and the contents are squeezed out from the opened portion and poured into a small dish or a dish.

  However, in the prior art shown in FIG. 1, the spout 5 is independent from the bag-like portion 4 as a liquid passage, but as an external structure, it is integrated with the bag-like portion 4 due to the presence of the seal portion 3. It was a connected structure and was not independent. Therefore, when the slit 6 is opened and the spout 5 is opened, the slit 6 reaches the bag-like portion 4, and the contents of the bag 4 in addition to the spout 5 are cleaved. In some cases, the contents are squeezed out and the contents are spilled into parts other than small plates and dishes.

  In addition, when the slit 6 is cut and expanded, the contents of the unsealed portion cannot be squeezed out from the spout 5 unless they are separated from the sealed package 1. For this purpose, it is necessary to cut up to the seal portion 3 adjacent to the spout 5. However, since the seal portion 3 generally has a high resistance to tearing, there is a problem that such a cutting operation becomes difficult.

  Furthermore, since the slit 6 is provided in the lateral direction with respect to the spout 5, the above-mentioned problem that “the cut end of the slit 6 reaches the bag-like portion 4” and “the slit 6 opening operation is performed. The problem of “being difficult” was further increased. The various problems described above are common even when the sealed package is a refill package having a relatively large size containing a large amount of liquid or fluid.

  Therefore, the present invention has a technical problem to be solved to solve the above problems in the prior art.

(Configuration of the first invention)
The structure of the first invention of the present application for solving the above-mentioned problem is that the package body is configured in a bag shape having an arbitrary planar shape, and the bag-shaped portion accommodates a liquid or fluid, and the bag-shaped portion. Independently from the outside structure, a sealed pouch is provided with a pour spout that is spatially connected to the bag-like portion and is sealed at the tip, and is formed with a slit for opening. -Di.

The structure of the third invention of the present application for solving the above problem is formed in such a manner that the spout according to either the first invention or the second invention fits within the planar outline of the package body. A hermetically sealed package.

(Configuration of the fourth invention)
The structure of the fourth invention of the present application for solving the above-mentioned problem is that the opening slit according to any one of the first to third inventions is formed in an oblique direction toward the tip side of the spout. It is di.

(Structure of the fifth invention)
The structure of the fifth invention of the present application for solving the above-mentioned problem is that the slit in the spout according to any one of the first to fourth inventions is formed at least from the base end of the spout with a finger pressing width. It is a hermetically sealed package.

(Effect of the first invention)
In the sealed package of the first invention, since the spout is independent of the bag-like portion from the outside structure, when the opening slit is widened to open the spout 5, the slit cut end There is no fear of reaching the bag-like part. Therefore, unlike the prior art described above, there is no possibility that the contents are squeezed out from the opening portion of the bag-like portion in addition to the spout, and the contents are not spilled into portions other than the small plates and dishes.

  Further, when the slit is widened, the spout is independent from the bag-like portion in terms of the external structure, so that the fragment of the opening can be easily separated from the package body. As a result, it is easy to squeeze out the contents from the spout.

(Effect of the second invention)
In the sealed package according to the second aspect of the invention, since the knob for protruding the side is provided on the tip side from the slit in the spout, the slit is widened with a finger to separate the tip of the spout. It will be easier.

(Effect of the third invention)
In the sealed package of the third invention, the spout is formed so as to be within the outline of the planar shape of the package body. Therefore, when handling in the manufacturing / distribution stage of the sealed package, the spout and the handle for picking may be caught on other items, or the spout for the other sealed package or for picking. It won't cause troubles such as getting caught on the handle, making it difficult to handle or opening the spout.

(Effect of the fourth invention)
In the sealing package of the fourth invention, since the slit is formed in an oblique direction toward the tip end side of the spout, the force for opening the spout when opening the spout is applied to the tip end side of the spout. It becomes easier to open the spout.

(Effect of the fifth invention)
In the sealed package according to the fourth aspect of the invention, since the slit is formed at least a finger pressing width from the base end of the spout, the base end of the spout is held by one finger and pressed. The opening operation of pulling with the other finger held on the tip side portion can be facilitated. Moreover, since the liquid passage of the spout is closed with fingers in the opening operation, it is possible to prevent a problem that the contents are ejected from the spout.

  Next, the first to fifth embodiments of the present invention will be described including the best mode. In the following, the term “present invention” simply refers to each of the above-mentioned inventions collectively.

[Shape package shape and structure]
The hermetic package of the present invention is configured in a bag shape whose package body has an arbitrary planar shape. The planar shape of the package body is not limited to a square or a rectangle, but may be a circle or an ellipse, or may be a shape imitating the shape of an alphabet character or an animal from the viewpoint of design.

  The sealed package has a bag-like portion containing a liquid or fluid as a content, and the bag-like portion is spatially communicated with the bag-like portion independently of the external structure and sealed at the tip. And a spout which is a thin liquid passage. An opening slit is formed at the spout. The spout and opening slit will be described in detail later.

  This hermetic package is formed by, for example, bonding the above-mentioned pair of resin films having an arbitrary planar shape with an adhesive or by means such as heat sealing at a certain portion, so that the bag-like shape is formed by the unbonded portion. The part and the spout are formed.

[Application and size of sealing package]
The use and size of the sealing package according to the present invention are not limited. The hermetic package can contain any kind of liquid or fluid such as soy sauce, dressing, shampoo and the like.

  Further, the hermetically sealed package can be a small-sized package that contains a relatively small amount (for example, about 2 mL to 20 mL) of soy sauce, dressing, shampoo and the like. Sealed packages of these sizes include, for example, a sushi sauce package used at a sushi restaurant, a package of soy sauce, sauces, dressings, etc. used in a convenience store or catered lunch box attached to a lunch box. There are applications such as shampoo packages installed in washrooms and bathrooms.

  Further, the sealed package can be a large-sized refill package containing a relatively large amount (for example, about 30 mL to 500 mL) of soy sauce, dressing, shampoo and the like. Sealing packages of these sizes are generally constructed relatively thickly with a thick resin material.

[Spout]
The spout is formed with a structure that is independent from the bag-like portion of the package body in terms of external structure and is in spatial communication with the bag-like portion.

  Here, “independently on the external structure” is not formed integrally with the bag-like portion due to the presence of a seal portion or the like as in the prior art shown in FIG. Means that it is formed with an independent shape separated from the bag-like portion. The phrase “in communication with the bag-like portion” means that the internal space of the bag-like portion and the internal space of the spout are in communication with each other so that the contents can be distributed.

  It is preferable to provide a knob handle that protrudes in the lateral direction with respect to the axial direction of the pouring spout at the tip end side of the slit in the pouring spout. Although the shape of this handle is not limited, it is preferable to make it easy to pick with a finger.

  Furthermore, the spout is formed so as to fit within the outline of the planar shape of the package body, in other words, toward the inner periphery of the outline of the planar shape of the package body. A configuration in which a cut portion is formed and, as a result, a spout is formed is preferable.

[Slit for opening]
The spout is provided with a slit for opening. This slit is formed in the peripheral wall part which comprises a pouring spout at the depth just before cut | disconnecting to the liquid flow path of a pouring spout. Therefore, when the slit is widened, the liquid passage of the spout is opened to the outside, and the contents of the sealed package can be squeezed out through the spout.

  In the case where the handle for picking is provided at the spout as described above, the slit is provided on the base end side with respect to the handle, and the slit cutting direction with respect to the axial direction of the spout is not limited. However, it is more preferable that the slit is formed in a direction aligned with the protruding direction on the lower end side of the handle and in an oblique direction toward the tip end side of the spout. Furthermore, it is preferable that the slit in the spout is formed at least a finger pressing width away from the base end of the spout.

  Embodiments of the present invention will be described below with reference to the drawings. Of course, the technical scope of the present invention is not limited by these examples.

(Example 1)
In the embodiment shown in FIGS. 2 to 5, the sealed package 7 is formed in a bag shape having a square plane shape as a whole. The hermetic package 7 has a bag-like configuration in which a pair of resin films 8 are bonded to each other at the seal portion 9 by adhesion or heat sealing, and the bag-like portion 10 contains a liquid or fluid as contents. .

  2 is a perspective view showing the overall appearance of the sealed package 7. FIGS. 3 to 5 are shown in a state where a pair of resin films 8 are peeled off for convenience (the seal portion 9 is hatched). Are doing).

  Further, the bag-like portion 10 is provided with a spout 11 that is a thin liquid passage that communicates with the bag-like portion 10 and is sealed at the tip. The spout 11 is formed with a slit 12, which is a cut for opening, in an oblique direction toward the tip end side of the spout. Further, a handle 13 for picking that projects laterally is provided at a portion of the pouring spout 11 immediately on the front end side of the slit 12.

  As shown in FIG. 4 in an enlarged manner, such a spout 11 is formed as a result of the recess 14 being formed in the sealed package 7 from the peripheral edge toward the inner peripheral direction. Therefore, the spout 11 is in communication with the bag-shaped portion 10 and is independent from the bag-shaped portion 10 in terms of the external structure. Moreover, the spout 11 is formed in a shape that fits within the outline of the planar shape of the sealed package 7.

  In the spout 11, the distance from the base end to the opening slit 12 has a length that can be pressed with a finger.

  In FIG. 2, the bag-like portion 10 reaches the upper end portion of the sealed package 7, but the bag-like portion 10 extends to the base end portion of the spout 11 as shown by an imaginary line (two-dot chain line) in FIG. 2. It is good also as a structure which reaches | attains, and all the upper parts are good also as the seal | sticker part 9. FIG.

(Operation / Effect of Example 1)
In the sealed package 7 of Example 1 configured as described above, the spout 11 is independent from the bag-like portion 10 in terms of the external configuration, and therefore the opening slit 12 is widened to open the spout 11. When doing, there is no fear of cutting off parts other than the spout 11. Moreover, although the spout 11 has been opened, there is no trouble such as the portion that has been cut out remains unsuccessfully separated from the sealed package 7 and interferes with squeezing the contents.

  Furthermore, when pouring the contents into a container or the like, since the spout 11 is independent from the bag-like portion 10 in terms of the external configuration, the spout 11 can be poured into the opening of the container. Therefore, even if the opening of the container is small, the contents can be poured without leaking outside.

  Moreover, since the length from the base end of the spout 11 to the opening part (the cut part of the slit 12) of the spout 11 has a length that can be pressed with a finger, the spout 11 is pinched with fingers when the spout 11 is opened. By pressing with, the contents will not scatter.

  On the other hand, since the slit 12 for opening and the shape of the lower end part of the handle 13 are formed in an oblique direction toward the tip side of the spout 11, the force for holding the sealed package 7 when opening the spout 11 Since the pulling force of the handle 13 can be applied in the opposite direction, it can be opened with less force than the conventional sealed package.

  Further, since the spout 11 is formed so as to fit within the outline of the planar shape of the sealing package 7 due to the formation of the recess 14, the handle 13 may be caught by another article or other sealing. There is no trouble that the spout 11 is accidentally opened by being caught on the spout 11 of the package 7 or the handle 13 for picking.

(Example 2)
In the sealed package 15 according to the second embodiment shown in FIG. 6, the spout 16 is formed in a state protruding from the planar outline of the sealed package 7. In other respects, the configuration is the same as that of the first embodiment. Therefore, the same actions and effects as those of the first embodiment can be expected within a range in which the configurations are common.

(Example 3)
In the sealed package 17 according to the third embodiment shown in FIG. 7, the spout 18 is formed in a state of projecting from the outline of the planar shape of the sealed package 17, and the spout 18 is for picking. There is no handle. The slit 19 provided in the spout 18 is transverse to the axial direction of the spout 18. In other respects, the configuration is the same as that of the first embodiment. Therefore, the same actions and effects as those of the first embodiment can be expected within a range where the configurations are common.

  The present invention provides a convenient sealed package that does not cause various troubles when opening the spout or squeezing out the contents.
