Abstract

An upper presser constituting a sealing tool is made as small as possible so as not to interfere with handling of a load. Cardboard boxes and seals should be sealed so that they are not overwhelmed. The lower presser has a “long length width” sufficient to hold the pair of outer lids so that they do not float upward. Was assumed to have a short “short length”. That is, the function of pressing the pair of outer lids so as not to fall downward is assumed to be “take a method depending on the presence (support) of the pair of inner lids”. By adopting the above method, the upper presser can be made smaller than the conventional one. In addition, it has become possible to seal the cardboard box and the sealing tool without excessive stress. [Selection] Figure 7

Description

The present invention relates to a sealing device for a packaging box such as a cardboard box having a pair of inner lids and a pair of outer lids.
The present sealing tool relates to a sealing tool that seals the pair of outer lids by connecting them together. In other words, the sealing tool is attached to any position of the joint line of the pair of outer lids without entanglement of the sealing tool with the inner lid.
For example, those of Patent Documents 1 and 2 are this kind of sealing tool.

  The sealing device shown in Patent Documents 1 and 2 is sufficient to hold the pair of outer lids together with a lower presser having a length (or diameter) sufficient to hold the pair of outer lids so that they do not float upward. It also has an upper presser with a length width (or diameter).

Hereinafter, for the upper presser, a length width sufficient to hold the pair of outer lids so as not to fall downward is also referred to as a “long length width”.
In addition, regarding the lower presser, a length sufficient to hold the pair of outer lids so as not to lift upward is also referred to as a “long length”.

  That is, the sealing device shown in Patent Documents 1 and 2 has both an “upper presser having a long length” and an “lower presser having a long length”, and an upper presser having a long length and a long length. It has a “deep pinch” made up of a wide presser foot.

  The upper presser with a long width is handled as a load when other boxes are stacked on top of the sealed cardboard boxes. It will be a hindrance to doing.

The conventional sealing method that locks locally with a deep pinch is difficult for both the cardboard box and the sealing tool.
Since the outer lid of the cardboard box has a property of bending (bending), it becomes particularly difficult when a heavy box is stacked.

JP-A-11-59663 European Patent Application No. 1671889

The greatest problem of the present invention is how to reduce the size of the upper presser by a method as long as it does not hinder the function as the sealing tool.
That is, it is intended to prevent the cardboard box and the sealing tool from being overwhelmed, and to prevent or reduce the above-described troubles in handling the cardboard box. In other words, get a practical seal.

  It should be noted that it can be attached to any position of the joint line of the pair of outer lids, can be sealed without entanglement of the sealing device directly with the inner lid, and a commercially available cardboard box. It can be used as it is.

Among the functions of the conventional sealing tool, the function for pressing the pair of outer lids so as not to fall down is taken as a method depending on the presence of the pair of inner lids. That was assumed to employ a method that depends on the receiving support for the inner lid.

The sealing tool of the present invention has a “long width” sufficient to hold the pair of outer lids so that the pair of outer lids do not float upward. However, the pair of outer lids do not fall downward. It was assumed to have a length that is insufficient to hold down (hereinafter also referred to as “short length”).
The present invention does not assume that the upper presser has a function sufficient to hold the pair of outer lids so that the pair of outer lids does not fall downward, and the function depends on the presence (support) of the pair of inner lids. It is said that.
By adopting this method, the size of the upper presser can be reduced. That is, the length of the upper presser can be shortened.

Incidentally, the upper presser can be held so that the pair of outer lids do not escape upward or can be hooked, that is, a short width that can slightly hold the edges of the pair of outer lids. It was supposed to consist of
In other words, if it is assumed that there is no inner lid (supporting support), the pair of outer lids will fall down (inside the box).
The above will be described in detail with reference to FIG.

It has become a form to eliminate or lighten the trouble in handling cargo.
In addition, the sealing can be carried out without difficulty for both the sealing tool and the packaging box, and a sealing tool suitable for practical use can be obtained.

It is a conventional sealing tool (the thing of patent document 1). It is a sealing tool (Example 1) of this invention. FIG. 3 is an explanatory diagram according to FIG. 2. It is a conventional sealing tool (the thing of patent document 2). It is a sealing tool (Example 2) of this invention. It is explanatory drawing which concerns on FIG. It is a figure explaining the function of the sealing tool of this invention. It is a figure explaining the function of the sealing tool of this invention.

In explaining the embodiment, the meanings of top, bottom, vertical, horizontal, left, right, beyond, front, inside, outside, back, and front are properly used while viewing the figure.
The packaging box will be described with a cardboard box in mind.
A cardboard box has a width surface and a length surface. Expressed mainly from the direction of looking at the width.
In this book, a pair of outer lids are expressed in the form of looking left and right, that is, left and right. In addition, it is expressed in the form of seeing the joint of a pair of outer lids in the vertical line.

The sealing tool in the sealed state is referred to as the length side when viewed from the direction of viewing the width surface (C1) of the cardboard box, and the width extending from side to side when viewed from the same direction is referred to as the length width. The side surface on the length side is called the length side surface.
The side of the sealing tool in the sealed state viewed from the direction of viewing the length surface (C2) of the cardboard box is referred to as the width side. The side surface on the width side is referred to as the width side surface.
The sealing 緘state refers to the state of mounting the closure to a predetermined posture.
In the expression of looking at a sealing tool that is not in a sealed state, it is also referred to as a length side, a length width, a length side surface, a width side, and a width side surface in the same manner as a sealing tool in a sealed state.

In a state where it is assumed that there is no inner lid, the sealer has a form in which the pair of outer lids falls downward (inside the box) when subjected to a downward pressing action from above. It is made up of.
Each figure seen from the side omits the presence of the inner lid, so please include this point.

  The sealing tool does not take a method of entanglement of the sealing tool itself with the inner lid. Therefore, unless otherwise specified, the description and description are based on the premise that the sealing tool itself is not entangled with the inner lid, or is not entangled with the inner lid.

This sealing tool takes a form in which the lid is closed by a method in which the sealing tool is not entangled with the inner lid, and there are two forms because of the difference in the attachment method when sealing.
One is a form as shown in Patent Document 1, and is a form having a pinch opening facing one of the left side and the right side of the column in the form seen from the side.
The other is a form as shown in Patent Document 2, which has a pinch opening facing both the left side and the right side of the support column as viewed from the side.

  Hereinafter, the sealing device of the present invention will be described in comparison with those of Patent Documents 1 and 2.

Incidentally, if the shape of the lower presser is not circular but is a shape extending in the longitudinal direction, that is, the length of the length side surface is longer than the width of the width side surface (length extending left and right). In the case of the one formed in the form, “rotate the upper presser and pass the upper presser over the pair of outer lids, and at the same time set the longitudinal direction of the lower presser (the direction in which the length extends) of the pair of outer lids. It is also a figure which shows the state made | formed by the operation of turning to the direction which crosses a seam line (vertical line).

FIG. 4 will be described.

FIG. 5A is a perspective view. FIG. 5 (2) is a side view of the width side surface (viewed from the direction A).
FIG. 5 (3) is a side view of the length side surface (viewed from the B direction).

  The focus of the difference between the conventional sealing tool and the sealing tool of the present invention is mainly the difference in the length and width of the upper presser (D1) in FIGS. 4 (3) and 5 (3). That is, it is a difference in concept related to the length and width of the upper presser. This will be described again later.

FIG. 6 will be described.
FIGS. 6 (1) and 6 (3) are views showing the process of sealing the sealing tool shown in FIG.
6 (2) is a partial view of the state of FIG. 6 (1), and FIG. 6 (4) is a partial view of the state of FIG. 6 (3) viewed from the direction of viewing the width surface (C1) of the cardboard box.
FIG. 6 (1) is a view showing a state in which the pair of outer lids are in a floating state (semi-closed state), and the sealing tool is inserted between the joints. From this state, the pair of outer lids are pushed down together with the sealing tool to fold the pair of outer lids into a flat state, and then the upper presser is rotated to connect the pair of outer lids into a sealed state.
FIG. 6 (3) is a diagram showing a sealed state, that is, a state in which the upper presser is operated and the longitudinal direction of the lower presser is directed in the direction crossing the joint line (vertical line) of the outer lid. FIG.

FIG. 7 will be described.
In this sealing tool, the lower presser has a long width sufficient to hold the pair of outer lids so that the pair of outer lids do not float upward. On the other hand, “the upper presser foot is formed with a short length and width that is insufficient to hold the pair of outer lids so as not to fall downward”.
In other words, the function of pressing the pair of outer lids so as not to fall downward is “take a method depending on the presence (supporting support) of the pair of inner lids”.

  FIG. 7 shows an upper presser having a short length and width that the pair of outer lids is not sufficient to hold down so that it does not fall downward (inside the box) when receiving an action (P1) of pressing down from above. It is a figure explaining about.

FIG. 7 (1) is a partial view of the sealing device when the sealing state is viewed from the direction of viewing the width surface of the cardboard box, and is the same as the diagrams shown in FIGS. 3 (4) and 6 (4).
FIG. 7 (1) is a partial view showing a state (sealed state) in which a pair of outer lids are connected in a substantially flat state.

What is desired to be described with reference to FIG. 7 is that in the sealed state shown in FIG. 7 (1), however, when an action (P1) of pushing down from above is received in the state where the inner lid is not present, FIG. (2) As shown in (3), the pair of outer lids and the sealing tool fall down while being pushed. It constitutes the upper presser of the short length width (G1) that forms the mouth ".
In this document, such a short length width (G1) is referred to as “a length width that is insufficient to hold down so as not to fall downward” or “a short length width”.

In other words, this sealing tool has a length width on the length side, and the lower presser (D3) has a “long length width (G2)” sufficient to hold the pair of outer lids so that they do not float upward (outside). It is composed. On the other hand, the upper presser (D1) has a “short length width (G1)” that is insufficient to hold the pair of outer lids so as not to fall downward.
It is said that the lower presser with a long length and the upper presser with a short length form a “shallow depth of mouth”.

The above shape is for preventing the outer lid (C4) and the sealing device from being overwhelmed and for preventing the upper presser from obstructing the handling of the load. For example, when the load of other boxes to be stacked is excessive, the sealing device can escape (disengage) from the outer lid as shown in FIGS. 7 (2) and (3). It takes the form of being released .

  Since this sealing tool depends on the presence (supporting support) of the pair of inner lids for the function of holding the pair of outer lids so as not to fall downward, the pair of outer lids actually have the pair of outer lids shown in FIG. 2) Although it does not fall as shown in (3), it has play (room for movement) as shown in Fig. 7 (2) and (3) in the relationship between the sealing tool and the outer lid. It is to explain that.

FIG. 7 (4) is a diagram for supplementarily explaining the characteristics of the cardboard box.
The shape shown in FIG. 7 (1) may be gradually bent as shown in FIG. 7 (4) during use.
Since this sealing tool has a play in the form of pressing a pair of outer lids, it is possible to appropriately keep the sealed state in conformity with such bending. Incidentally, in FIGS. 7 (2) and 7 (3), the outer lid without bending is shown as being connected, but even the outer lid with bending can be properly sealed.

The outer lid of the cardboard box has a property of bending gently. There is also deflection over time. There is also deflection caused by the load of other boxes that are stacked.
The sealing tool is configured to adapt to the bending of the outer lid. In the present invention, since the upper presser is made small and thin, and the presence of the upper presser is buried in the flexure, the opening that has the greatest flexure so as not to interfere with the handling of the load or to hinder the trouble. It can also be attached to the center position of.

FIG. 7 (4) is a view showing a state in which the inner lid (C3) is bent together with the outer lid (C4).
As shown in FIGS. 3 and 6, the present sealing tool is basically used at a position near the center of the opening, that is, within a distance between the pair of inner lids and the inner lids (a position where there is no inner lid). , Where the inner lid does not reach). Therefore, as shown in FIG. 7 (4), the presence of the inner lid (C3) can be seen on the front side of the lower presser (D3) as to see the watermark from the direction of viewing the width of the cardboard box.

As can be seen in FIGS. 7 (2) and 7 (3), when receiving the action of pushing down from above (P1), the sealing tool falls down while being pushed. The presence of an inner lid.
FIG. 7 (4) shows a situation in which the inner lid supports and supports a pair of outer lids or supports a pair of outer lids in place of an upper presser with a short length.
For example, even if the upper presser has a long length and width, as long as the sealing method is used to hold it locally, it will eventually be left to the support of the inner lid as shown in FIG. 7 (4). Become.
At this time, for example, if the upper presser has a long length and width, it takes a great deal of effort both for the upper presser and for the outer lid that is pressed by the long length and width of the upper presser. The method should not be overwhelmed, and the present invention is based on such a concept.

  This sealing tool is not intended to be long enough to be pressed down so that the pair of outer lids do not fall down, and its function depends on the presence (support) of the pair of inner lids. The support by the pair of inner lids is not inferior to the function of the upper presser that holds the pair of outer lids of the conventional sealing device (the ones of Patent Documents 1 and 2) so as not to fall downward.

In the embodiment of the present sealing device, for example, in the case of a cardboard box (an orange box close to the opening) having a length of 38 cm and a width of 30 cm, that is, when the width of one outer lid is 15 cm. In the examples, the length of the upper presser was 2.5 to 4 cm, and the length of the lower presser was 8 to 16 cm. The length of the lower presser was about 12 centimeters, and the length of the upper presser was about 3 centimeters.
Incidentally, the above-mentioned actual feeling or evaluation is merely an example, and it goes without saying that various results may be obtained depending on the state of the cardboard box, the thickness of the outer lid, the strength of the paper quality, or the person who performs the evaluation. How many centimeters the length width may be set arbitrarily.

  In the case of Patent Documents 1 and 2, when considering the length width for holding the pair of outer lids so that they do not fall downward, considering the outer lid of the same size as the object, the length of the upper presser is It is considered to be about 8-12 cm. In comparison, the length of the upper presser in the sealing tool can be set to a size (small) of about one-half to one-fourth.

  Incidentally, even when the lateral width of the outer lid is large and the length of the lower presser is increased in proportion thereto, it is not necessary to increase the length of the upper presser in proportion thereto. In other words, the upper presser in the present sealing tool does not have the shape (or concept) in the conventional sealing tool that “forms a deep insertion port with the lower presser”.

FIG. 8 will be described.
FIG. 8 illustrates a lower presser having a width sufficient to hold the pair of outer lids so that they do not float upward (outward) when the pair of outer lids are pushed upward (from the inside of the box) (P2). FIG.
FIG. 8 (1) is a partial view of the sealing device when the sealing state is viewed from the direction of viewing the width surface of the cardboard box, and is the same as the diagrams shown in FIGS. 3 (4) and 6 (4). 8A is a partial view showing a state in which a pair of outer lids are connected in a substantially flat state.

If the length of the lower presser is short as shown in Fig. 8 (2) or the length of the lower presser is halfway as shown in Fig. 8 (3), When the push-up action (P2) is received, the pair of outer lids are lifted upward as shown in the figure.
As shown in Fig. 8 (4), the lower presser in this sealing tool has a required length width (G2) that is stable when a pair of outer lids are connected flatly, or a sufficient length width. (G2).
Of course, the required length width to stabilize in a state where the pair of outer lids are connected flatly is referred to as “a length width sufficient to hold it so that it does not float upward” or “a long length width” in this document. It is what you call.

For the lower presser, it may be arbitrarily set how much the required length width is to be set, or how much the sufficient length width is to be set. Incidentally, it is desirable to set in consideration of not only the width of the outer lid but also the thickness and strength of paper.
The sealing tool of the present invention is a sealing tool that can be attached at a position where the inner lid does not reach, or a sealing tool that can be used without directly tangling the sealing tool to the inner lid, so that the pair of outer lids can be pressed so as not to float upward. As a function, the lower presser is assumed to have a long length. It is better to set the length of the lower presser to be longer with a view to safety (safety).

The present invention does not mean that the length of the upper presser is relatively shorter than the length of the lower presser. As illustrated in FIG. 7, when receiving the action of pushing downward from the top (P1), the pair of outer lids are depressed while being pushed, and finally short enough to come off from the pinch of the sealing tool. It is the width.
From the side of the sealing tool, when it receives an action of pushing down from above (assuming that there is no inner lid), the sealing tool falls down while being pressed, It is said that it will come out of the lid.
In short, as a degree of the length of the upper presser or as a pinch shape, it is configured so that it is released from the pair of outer lids while being pressed when subjected to the action of pressing down from above. That is.

  Since Patent Documents 1 and 2 are each said to “hold or hold a pair of outer lids in a sealed state with an upper presser and a lower presser”, in contrast to the present sealing tool, Obviously it takes a different form.

  In addition, the thing of patent document 1, 2 does not have the concept or technical idea of "short length width" said by this sealing tool.

As described above, the “viewing form on the side surface of the length side”, which is the main point of the present sealing device, has been described. The experiment was conducted with the lateral width of the presser being about 4 cm (in the case shown in FIG. 5).
Although the shape seen on the side surface on the width side is not limited or restricted, it is preferable that the lateral width of the upper presser is not too long.

  The following are general supplementary items.

In this document, in order to explain the difference from the conventional sealing device in an easy-to-understand manner, the form of the conventional sealing device is shown in the form of sliding as it is, and the length and width of the upper presser are expressed so that the difference can be understood. However, as long as the function as the main sealing tool is not impaired, the shape, contour, size (size), design, form, etc. of the upper presser may be arbitrarily determined.
In addition, although it does not limit about the material used and a material, the thing of the material which does not bend is good for a lower presser. The strut should be made of strong material. In the examples, a metal wire of # 12 (2.6 to 2.5 mm diameter) was used.

Although the present invention has been described with the cardboard box as the main object and with the cardboard box in mind, the present invention can be applied to or used in boxes other than the cardboard box.
In this book, these boxes are collectively called packaging boxes.

  The technical idea of the present invention is not limited to those of Patent Documents 1 and 2, and can be applied to other sealing devices formed by connecting a lower presser and an upper presser.

  The entire contents of the present invention are described through the entire drawings, and the technical contents described in the claims are not limited by the technical contents described in the individual drawings.

This concludes the main discussion of the sealing tool.
The following is "with regard to the conventional sealing device (the ones of Patent Documents 1 and 2), the lower presser has a required length enough to hold the pair of outer lids so that they do not float upward, and the upper presser also has a pair of outer lids. Has a required width enough to hold down so that it does not fall downward, that is, it has a function of holding or holding a pair of outer lids in a sealed state as a sealing tool itself. It is stated.

  The sealing device of Patent Document 1 describes in its specification “in a state where the connecting member is disposed between the lids of the container, the holding member is rotated around the connecting member, and the surface of the receiving member and the holding member It is described that it is a container clip with a double-open lid that can be closed by pressing both lids by sandwiching the lids with the surface.

The thing of the patent document 1 has shown the form whose diameter of an upper presser is larger than a lower presser as the form which represents the same literature in the FIG.9 (B).
FIG. 13 shows the upper presser having a smaller radius than the lower presser. “The radius relationship may be reversed. In this case, the material can be reduced.”
FIG. 14 shows a case where “the lower presser is a hexagon and the upper presser is a rectangle”, and “the shape of the lower presser as well as the upper presser as shown in FIG. As long as it is optional. "
As can be seen from these, it does not have or suggest an idea or concept related to the technical idea of the present invention.

As shown in FIGS. 1 and 2 of the sealing tool of Patent Document 2, the length of the upper presser is shorter than the length of the lower presser, but it is relatively short. , As a matter of fact, not short. In other words, the upper presser has a width sufficient to hold the pair of outer lids so that the pair of outer lids do not drop down unnecessarily, even if the upper presser receives an action of pressing it downward.
In the Japanese abstract, “the lid 2 is held between the upper plate 3 and the holding plate 5” is described. Further, according to FIGS. 5 and 6 of the document 2, the sealing device itself is sealed without depending on the method depending on the support of the inner lid, or regardless of the method of winding the sealing device around the inner lid. It shows that it has the form which completes.
In other words, even if it receives the action of pushing down from above, the upper presser has a length and width sufficient to hold down so that it does not fall down (inside the box) and the action of pushing up from below, It consists of a lower presser having a length and width required to hold it so that it does not float (outside the box).

Although the thing of patent document 1 and the thing of patent document 2 are a little different in the expression of a figure, both are "clamping" or "holding" with an upper presser and a lower presser. .
In other words, regardless of whether the inner lid is present or not, the conventional sealing tool is “an upper presser having a required length and width enough to hold down so that it does not fall downward when subjected to an action of pressing downward from above” and “ When receiving an action of pushing up from below, a lower presser having a required length and width sufficient to hold it up so as not to float upward is constituted.
The grounds for interpreting the conventional sealing device have been described above.

It has become a sealing tool that eliminates or reduces problems in handling goods such as storage and transportation.
It can be used in a wide range of applications from home use to industrial use.
