Description

  The present invention relates to a storage body and a chuck for clearly showing opening of the storage body.

Opening and closing chucks that swing the fitting portion on the line have been widely used in the past as being extremely useful in that the bag can be repeatedly opened and closed. However, the advantage of the opening / closing chuck is that it is difficult to clearly show the trace of tampering inside the bag. Therefore, proposals as shown in Patent Documents 1 and 2 have been made from the viewpoint of clearly indicating that the package has been opened. In these proposals, a part of the bag other than the opening and closing chuck is sealed by welding or the like, and a weakening line such as a perforation for opening and closing is provided near the sealing portion, so that the bag can be opened. In this case, the opening / closing chuck is opened and the weakening line is broken.
Further, Patent Document 3 is an open / close chuck with a slider, and the slider cannot move from the closed position until the mischievous proof feature that can be broken only once is broken, or the slider does not move. Proposals have been made in which the mischievous proof feature is broken by moving from the closed position.
However, in these proposals, after the contents are stored in the bag, it is necessary to seal the bag with welding or an adhesive (Patent Documents 1 and 2), or to attach the chuck by welding or the like ( Patent Document 3), it takes time for sealing after the contents are stored, or a special device is required.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The unwrapping manifestation chuck 10 shown in FIG. 1 comprises a pair of synthetic resin first chuck half 11 and second chuck half 21.

  The first chuck half 11 includes a male fitting portion 12 and a male support portion 13 that supports the male fitting portion 12. The male support portion 13 includes a base portion 14 and an intermediate portion 15. A portion connecting the male fitting portion 12 and the base portion 14 is an intermediate portion 15. At least a part of the base portion 14 is fixed to a sheet constituting the storage bag 31 by an adhesive portion 17 such as welding or adhesive. Further, the storage bag 31 and the first chuck half 11 can be integrally formed. These shapes can be implemented by changing as appropriate within the range in which the function can be achieved. In this example, the base portion 14 has a band shape having a width in the vertical direction (the direction in which the contents are put in and taken out). A middle portion 15 having a narrow width extends from the middle in the left-right direction (direction intersecting the direction in which the contents are put in and out), and a male fitting portion 12 having a larger vertical width than the middle portion 15 is formed at the tip. The position where the intermediate portion 15 is provided can be changed as appropriate, and is not limited to the middle of the base portion 14 and may be shifted in the vertical direction. Further, when the fitting function of the male fitting portion 12 can be fulfilled, the middle fitting portion 15 may be omitted and the male fitting portion 12 may be directly formed on the base portion 14. Although the adhesion part 17 is made into one place each on the upper and lower sides of the base 14, the whole base 14 may be adhere | attached and it can change suitably.

  The second chuck half 21 includes a female fitting portion 22 and a female support portion 23 that supports the female fitting portion 22. The female fitting portion 22 is elastically deformed to receive and forcibly fit the male fitting portion 12. The female support portion 23 includes a base portion 24 and an intermediate portion 25. A portion connecting the female fitting portion 22 and the base portion 24 is an intermediate portion 25. At least a part of the base 24 is fixed to a sheet constituting the storage bag 31 by an adhesive portion 27 such as welding or adhesive. Further, the storage bag 31 and the second chuck half 21 can be integrally formed. These shapes can be changed and implemented as appropriate within the range in which the function can be achieved. In this example, the base portion 24 has a band shape that is wide in the vertical direction (the direction in which the contents are put in and out). An intermediate portion 25 having a narrow width extends from the middle to the left-right direction (the direction intersecting with the content insertion / removal direction), and a female fitting portion 22 that is bifurcated in the vertical direction is formed at the tip thereof. The male fitting portion 12 is forcibly fitted to the portion 22. The position where the intermediate portion 25 is provided can be changed as appropriate, and is not limited to the middle of the base portion 24, and may be shifted in the vertical direction. Further, when the fitting function of the female fitting portion 22 can be achieved, the intermediate portion 25 may be omitted and the female fitting portion 22 may be formed directly on the base portion 24. In addition, although the adhesion part 27 is made into one place on the upper and lower sides of the base 24, the whole base 24 may be adhere | attached and it can change suitably.

  At least one of the first chuck half 11 and the second chuck half 21 is provided with weakening lines 16 and 26. The weakening lines 16 and 26 may be provided on any of the male fitting portion 12, the male support portion 13, the female fitting portion 22, and the female support portion 23. It is advantageous to provide the support portion 13 and the female support portion 23, and in the example shown in FIG. 1A, the weakening lines 16 and 26 formed of perforations are provided on the base portions 14 and 24. Specifically, between the bonding portion 17 and the bonding portion 17 (in the drawing, near the lower end of the base portion 14 of the first chuck half 11) and between the bonding portion 27 and the bonding portion 27 (of the second chuck half 21). It is provided near the upper end of the base 24. In this example, the two weakening lines 16 and 26 are provided on both the first chuck half 11 and the second chuck half 21, but it is sufficient if they are provided only on one of them. Further, it may be provided near the upper end of the base 14 of the first chuck half 11 and near the lower end of the base 24 of the second chuck half 21.

  Further, as shown in FIG. 1 (B), not only the weak line 16 made of a perforation but also a weak line 26 made of a concave groove can be formed. In this example, it is provided in the intermediate portion 15 of the male support portion 13 and the intermediate portion 25 of the female support portion 23. The shape and structure of the weakening lines 16 and 26 can be implemented with various changes. In the example of FIG. 1B, the weakening line 16 has a perforation in which a penetrating portion with respect to the first chuck half portion 11 is provided intermittently, and the weakening line 26 has a concave groove shape with a reduced thickness. Although it is a part, it is good also as a combination type which connects the perforation part between perforations by a concave-groove part. The shape of the penetrating portion can also be changed as appropriate, and it may be a long hole along the tearing direction, a round hole with no directivity, or a hole extending in a direction intersecting with the tearing direction. The cross-sectional shape of the groove can also be appropriately changed, such as a wedge shape or a U shape. Further, the weakened portion is not limited to a linear one, and for example, the intermediate portions 15 and 25 may be thin as a whole, and may be easily broken. Moreover, it is good also considering the adhesion parts 17 and 27 which adhere | attach the base parts 14 and 24 with the sheet | seat of the storage bag 31 as a weak thing.

  What is important is that the fitting strength between the male fitting portion 12 and the female fitting portion 22 is designed to be larger than the breaking strength of the weakened portions (weakening lines 16 and 26). In short, when the storage bag 31 is pulled to pull the sheet of the storage bag 31 or the chuck 10 for revealing opening, the weakening line is removed before the male fitting portion 12 and the female fitting portion 22 are disengaged. 16 and 26 are torn. This fitting strength is only required to be slightly larger than the breaking strength, but it is desirable to provide a difference of 1.5 times or more from the viewpoint of eliminating instability due to variations in processing and materials.

  Next, FIG. 2 is an example in which the above-described opening and closing chuck 10 and a normal opening and closing chuck 33 are used in combination. The opening / closing chuck 33 can be substantially the same as the above-described opening and clarifying chuck 10 except that the weakening lines 16 and 26 are not provided. In the example of the figure, in the vicinity of the opening 32 of the storage bag 31, the opening clarification chuck 10 is attached on the upper side (the side closer to the opening end of the storage bag 31), and for opening and closing the lower side (the back side of the storage bag 31). A chuck 33 is attached. Thus, even when the weakening lines 16 and 26 of the opening indication chuck 10 are deliberately or accidentally broken, the sealing performance of the bag can be maintained as long as the opening and closing chuck 33 is not opened. However, the opening / closing chuck 33 may be provided above the opening manifestation chuck 10, and in some cases, the opening / closing chucks 33 may be provided on both upper and lower sides of the opening manifestation chuck 10.

Moreover, when it is carried out only with the chuck 10 for clearly showing the opening, the weakening lines 16 and 26 may be broken because the contents try to jump out of the opening due to vibration or impact during transfer or the internal pressure of the bag rises. possible. On the other hand, providing the opening and closing chuck 33 on the inner side of the storage bag 31 prevents the weakening lines 16 and 26 from being inadvertently broken. Thus, it is possible to prevent the fact that the cause of the breakage of the weakening lines 16 and 26 from the outside is the purpose of mischief or illegal use from the outside, or due to an impact during transfer or an increase in internal pressure.
In particular, in this example, regarding the fixing of the opening / closing chuck 33 to the sheet, the bonding of one base 34 is fixed by both the upper first bonding portion 36 and the lower second bonding portion 37. On the other hand, the other base 35 is bonded only to the upper third bonding portion 38, and the lower side is not bonded to the sheet. Thereby, when the storage bag 31 has high sealing performance, it is possible to prevent the opening / closing chuck 33 from being disengaged when the storage bag 31 is compressed and the internal pressure of the bag increases. That is, when the internal pressure of the storage bag 31 is increased by leaving only the upper third bonding portion 38 as the bonding location, the lower side of the other base portion 35 is separated from the sheet of the storage bag 31 and the one base portion 34 is approaching. As a result, the internal pressure is likely to be directly applied to the third bonding portion 38, and it is difficult to work directly in the direction in which the fitting portion of the opening / closing chuck 33 is separated, compared to the case where the lower portion of the other base portion 35 is bonded, The strength of the fitting portion increases.

  Next, FIG. 3 is an example of the combined chuck 41 in which the above-described opening and closing chuck 10 and the opening and closing chuck 33 are formed as one chuck. Specifically, two sets of a male fitting part 12, a female fitting part 22, and intermediate parts 15 and 25 are provided on the first chuck half part 11 and the second chuck half part 21 in the vertical direction. The base portions for the male and female fitting portions 12 and 22 and the intermediate portions 15 and 25 are combined base portions 42 and 43 that are continuous in the vertical direction. And the weakening lines 16 and 26 are provided with respect to the fitting part of one of the upper and lower chucks. The positions where the weakening lines 16 and 26 are provided can be changed as appropriate, as in the previous example, but in this example, they are provided in the intermediate parts 15 and 25 of the upper male support part 13 (and / or the female support part 23). ing. The weakening line can be provided in the base portions 42 and 43. In this case, it is necessary to provide one fitting portion so that it functions even after the weakening line is broken. Specifically, when a part of the base parts 42 and 43 is an adhesive part to the sheet of the storage bag 31, one intermediate part 15 and 25 from the adhesive part and the male fitting part 12 and the female fitting connected thereto. A weak line is provided in a portion excluding the portion 22. As a result, even after the weakening line is broken, at least one of the male and female fitting portions 12 and 22 can maintain a state of being connected to the bonded portion, and can function as an openable / closable chuck.

As described above, in the storage body using the opening manifestation chuck of the present application, the contents (including not only articles but also liquid and gas) are stored from the opening 32 of the storage body such as the storage bag 31. Thereafter, the unsealing chuck 10 is closed. The sealing of the storage bag 31 is completed only by this simple and quick work. If the opening 32 is opened so that an illegal act such as mischief is performed on the contents of the container, the weakening lines 16 and 26 are broken before the male and female fitting parts 12 and 22 are released. As a result, an unscheduled unauthorized access trace remains, which can contribute to improvement of safety.
