2. Description of the Related Art When using a liquid content, such as an adhesive or a chemical, contained in a flexible bag made of, for example, a synthetic resin, the upper end of the bag is first treated with a suitable tool such as a cutter. It is performed by opening it with a tool and opening the contents in a suitable container before use. In that case, if the contents are viscous, the contents cannot be completely taken out into the container simply by opening the opened portion of the bag. Therefore, conventionally, the entire bag is twisted and the bag is handled by hand many times to squeeze out the contents remaining in the bag.

[0003]

However, even if the above method is used, the contents are often left in the bag, and there is a problem that the contents are wasted.

Further, the work of twisting and handling the bag in order to open the bag and take out the contents is not only very troublesome, but also there is a possibility that the contents are scattered around, so that the hands, clothes, There was also the problem of making the surroundings dirty.

The present invention has been made in view of the above problems, and provides an apparatus capable of squeezing the contents out of the bag with good workability and without waste of the contents.

[0006]

A bag contents squeezing device according to the present invention is a device for squeezing a flexible bag containing a liquid contents and squeezing the contents. A fixed-side narrowing member and a movable-side narrowing member capable of abutting and separating from the fixed-side narrowing member are laterally provided on the upper portions of the pair of support legs having a spacing wider than the width dimension of the bag. While being hung, a bag breaking cutter is provided at a position below both of the pressing members.

[0007]

First, the container for receiving the contents is placed between the support legs, and the movable side squeezing member is separated from the fixed side squeezing member. Next, after inserting the bag between the fixed side squeezing member and the moving side squeezing member until the upper end of the bag is aligned with both the squeezing members, the moving side squeezing member is placed on the fixed side squeezing member side. Move
Hold the upper edge of the bag firmly with both squeezing members. When the bag is pulled up while keeping this state, the contents in the bag are prevented from moving upward by both narrowing members, and the lower part of the bag is gradually inflated by the contents and the internal pressure is increased. When the bag reaches a certain size, the bag surface comes into contact with the bag breaking cutter. Then, since the bag is under tension due to its internal pressure, the bag is broken only by contacting the bag breaking cutter, and the contents are discharged from the breaking portion into the container below. Further, by pulling the bag upward, the bag is uniformly handled by both narrowing members over the entire width, and the contents are squeezed out without leaving any excess.

As shown in FIGS. 1 and 2, the bag contents squeezing device 1 is for squeezing a flexible bag P containing liquid contents and squeezing the contents. , The fixed-side narrowing member 3 on the upper part of the pair of support legs 21 and 22 having an interval wider than the width dimension of the bag P, and the movement that can be brought into contact with and separated from the fixed-side narrowing member 3. The side squeezing member 4 and the side squeezing member 4 are provided horizontally, and a bag breaking cutter 5 is provided below the both squeezing members 3 and 4.

The support legs 21 and 22 are for supporting the fixed side squeezing member 3 and the bag breaking cutter 5. These support legs 21 and 22 are both formed in a trapezoidal shape, and their lower ends are connected to each other by a connecting plate 23. The spacing between the support legs 21 and 22 is set wider than the width dimension of the bag P, and the height dimension is such that the container R for receiving the contents can be accommodated below the fixed-side narrowing member 3. It is set to be sufficiently larger than the height dimension of R.
The shape of the support legs 21 and 22 is not limited to the trapezoidal shape.

The fixed-side squeezing member 3 cooperates with the moving-side squeezing member 4 to squeeze the bag P. In this example, a roll is used. The fixed-side narrowing member 3 is rotatably supported by the upper ends of the support legs 21 and 22 at both ends of its shaft core 31, and is laid across substantially parallel to the connecting plate 23. The fixed side squeezing member 3 is not limited to a roll, and may have a rod shape whose surface exhibits lubricity with respect to the bag P.

In the case of the present embodiment, the moving-side narrowing member 4 is a roll, like the fixed-side narrowing member 3. The moving-side narrowing member 4 is rotatable between the upper ends of a pair of narrowing arms 61 and 62 pivotally supported by pins 63 on the outer surfaces of the support legs 21 and 22, respectively, and , Is supported in parallel with the fixed-side narrowing member 3. The reference numeral 41 in the figure indicates the axis of the moving-side narrowing member 4. The lower ends of the squeezing arms 61 and 62 are interconnected by a tread plate 64, and when the operator steps on the tread plate 64, the moving side squeezing member 4 contacts the fixed side squeezing member 3. The moving-side narrowing member 4 is configured to be separated from the fixed-side narrowing member 3 by being brought into contact with each other and, conversely, by swinging the tread plate 64 upward. The moving-side narrowing member 4
Similarly to the fixed-side narrowing member 3 described above, the roll-shaped member is not limited to a roll, and may have a rod-like surface whose surface is slippery with respect to the bag P. Further, the means for bringing the moving-side narrowing member 4 into contact with or separating from the fixed-side narrowing member 3 is not limited to using the narrowing arms 61 and 62 having the above-described configuration, and the moving-side narrowing member Any other means may be used as long as it can firmly abut the fixed side narrowing member 3. Furthermore, the fixed-side narrowing member 3 and the moving-side narrowing member 4 do not necessarily have to be provided in parallel with the connecting plate 23, that is, horizontally, but may be provided with both being inclined in the same direction.

The bag-breaking cutter 5 is for contacting the bag P that has been squeezed and swelled by the above-described narrowing members 3 and 4 to break the bag P. This bag breaking cutter 5
In the case of this example, is installed between the support legs 21 and 22. The erected position is a position that does not hinder the accommodation of the container R between the support legs 21 and 22 and can reliably contact the squeezed and swollen bag P. The cutter 5 for breaking the bag is not limited to being provided between the support legs 21 and 22, but may be provided between the above-mentioned narrowing arms 61 and 62, and may correspond to the size of the bag P and how the bag P bulges. It may be movable. In that case, the bag breaking cutter 5 may be bent and formed in an appropriate shape so as not to hinder the swinging motion of the squeezing arms 61 and 62. Further, the cutter 5 used in the present embodiment is a blade-shaped cutter, but may be a needle-shaped cutter as long as it can be quickly ruptured.

Next, the operation of the bag content squeezing device will be described with reference to FIGS. 3 (a) to 3 (d). In the figure, the support leg 21 and the narrowing arm 61 located on the front side are omitted for convenience of illustration.

First, as shown in FIG. 3 (a), the support leg 2
While placing a container R for receiving the contents between 1 and 22,
The tread plate 64 of the squeezing arms 61, 62 is swung up to separate the moving-side squeezing member 4 from the fixed-side squeezing member 3.

Next, the bag P is inserted between the fixed side squeezing member 3 and the moving side squeezing member 4 until the upper end thereof is aligned with both the squeezing members 3 and 4, and then the squeezing arm 61. 3 and 62, the moving side narrowing member 4 is moved to the fixed side narrowing member 3 side as shown in FIG. Firmly sandwich with 4.

While maintaining this state, that is, the narrowing arm 6
When the bag P is pulled up while the tread plate 64 of 1, 2 is stepped down, the contents in the bag P are prevented from moving upward by the squeezing members 3 and 4, and the bag is gradually pulled up. The lower part of P expands due to the contents, and the internal pressure increases. When the bulge of the bag P reaches a certain size as shown in FIG. 3C, the surface of the bag P comes into contact with the bag breaking cutter 5. Then, since the bag P is under tension due to its internal pressure, the bag P is ruptured only by contacting the bag crushing cutter 5, and the contents are discharged into the container R below from the ruptured portion.

Further, as shown in FIG. 3 (d), the bag P is pulled up upward so that the bag P can be uniformly handled by the squeezing members 3 and 4 over the entire width, so that the contents L are not exhausted. Squeezed out.
