Description

The present invention relates to a pouch composed of a synthetic resin film or a sheet in which a plurality of synthetic resin films and a metal film are laminated, and efficient refilling is performed with the spout of the pouch opened. It is.

  In recent years, as containers for shampoos, rinses, liquid soaps, cosmetics, etc., from the viewpoint of effective use of resources, stationary type large containers equipped with dispensers that enable the appropriate amount of contents to be dispensed have been used. Pouches are widely used as containers for refilling contents.

  A pouch is a bag-like container composed of at least one sheet made of a synthetic resin film or a laminated sheet in which a synthetic resin film and a metal film are combined, and the amount of material used can be reduced. Since the production cost can be reduced, the refill container has particularly excellent advantages.

  By the way, the outlet of the pouch is thin like the main body, so the waist is weak and the walls of the passage may stick together, especially for contents with relatively high viscosity, refilling the contents The problem which took time to leave was left.

  As a prior art which aimed at the improvement regarding this point, a pouch provided with a fitting mechanism for maintaining a bent state with a flat plate shape at a spout has been proposed (for example, see Patent Document 1).

JP-A-11-152153

  The above-mentioned pouch can hold the spout in an open state, and even a high-viscosity content can be poured out relatively efficiently, but requires a complicated structure. There are disadvantages in that the manufacturing cost increases due to the number of assembling steps, and the operation of folding the hinge is also necessary when opening the pouch, which is not convenient.

  An object of the present invention is to propose a new pouch capable of efficiently refilling the contents while maintaining the spout in an open state without complicating the structure and increasing the manufacturing cost.

In the present invention, a sheet made of at least one synthetic resin film, or a laminated sheet in which a plurality of synthetic resin films and metal films are alternately laminated is overlapped, and a filling space for contents is provided between them. A pouch comprising a main body part to be formed and a spout having a passage leading to a filling space of the main body part,
In the initial state, they are overlapped in the passage of the spout, but a pair that forms an opening between them by pressing the ends close to each other and widens the passage to keep the spout open. Chips are arranged,
The tip is made of an elastic member that is restored to the initial state by releasing the pressing force, and the tip is simply a superposition of two elastic members, and swings with one end of the two elastic members as a hinge. One of a structure that can be connected, or one that has a structure in which both ends of two elastic members are swingably connected as hinges, and
The tip has a maximum diameter when the pressing force is applied to form the opening and is smaller than the size of the mouth of the container to be refilled with the contents, and when the pressing force is released, The pouch is set to a size that is held in the mouth of the container based on a restoring force .

  A pair of overlapping chips is placed in advance in the passage of the spout, and the opening of the spout is formed only by forming an opening between them by pressing the ends of the tips close to each other. Along with it.

  Before the pouch is opened, the spout is maintained in a flat state, so that it is not bulky when stacking or the like when packaging products, and efficient packaging is possible.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 is an external perspective view showing an embodiment of a pouch according to the present invention.

  1 in FIG. 1 is a main body portion of the container. The main body portion 1 is composed of a synthetic resin film sheet, a laminated sheet in which a plurality of these are laminated, or a laminated sheet in which a plurality of synthetic resin films and metal films are alternately laminated. By filling and joining at the end portions, a filling space for the contents is formed between them.

  Further, 2 is a knob that can be cut off by tearing along the line L, and 3 is a spout that is opened by tearing of the knob 2.

  Reference numeral 4 denotes a pair of chips (the overlapping surfaces are not bonded) arranged in the passage of the spout 3 in the overlapping state as shown in FIG. The tip 4 has higher rigidity than the main body portion 1, and an opening 4a can be formed between them as shown in FIG. The initial posture can be restored by releasing the pressure.

  As shown in FIG. 4, the lower region (A) located on the container body 1 side of the chip 4 is firmly fixed and held on the wall surface of the passage 3a of the spout 3 by an adhesive (sealant) or the like, while the upper region (B) is not bonded, and the upper portion of the chip 4 is exposed as shown in FIG.

  After the knob 2 is torn off, when the opening 4a is formed between the two ends of the chip 4 by pressing them close to each other, the passage 3a of the spout 3 is expanded and held open as shown in FIG. Thus, the contents to be refilled can be poured out in a short time.

  The size of the chip 4 (the maximum diameter when the opening 4a is formed by pressing the chip 4) is made smaller than the size of the mouth of the container to be refilled and inserted into the mouth of the container as shown in FIG. In this case, when the pressing force is released, the tip 4 is firmly held by the restoring force of the tip 4.

  The chip 4 has a structure in which one end is swingably connected via a hinge h as shown in FIG. 8 and both ends are connected via a hinge, as shown in FIG. What has been done (not shown) can also be applied, and this point is not limited.

  A pouch that can be refilled in a short time can be provided.

1 is an external perspective view of a pouch according to the present invention. FIG. It is the figure which showed the external appearance of the chip | tip. It is an external view of the state which pressed the chip | tip. It is a front view of the pouch shown in FIG. It is the figure which showed the opening state of the pouch shown in FIG. It is explanatory drawing of the refilling point of the contents. It is explanatory drawing of the refilling point of the contents. It is the figure which showed the other example of the chip | tip.
