Abstract

PROBLEM TO BE SOLVED: To solve the problems that for a conventional packing box (a cardboard or the like) there is no appropriate method and means for encapsulation at a site close to the center of an opening portion or any position of the opening portion nor appropriate method and means for connecting (encapsulating) stably a pair of outer lids.SOLUTION: A lower retainer of an encapsulation tool constituted by connecting the lower retainer to an upper retainer through a support post is set to have a certain length (length and width), and configured to be spring-loaded as appropriate so as to appropriately correspond to any outer lids even though the lids have somewhat different thickness and different hardness (paper quality). Alternately, a method for attachment of the capsulation tool with a certain length and width is set to accord to nearly two steps of operations ( procedures) in which an operation for encapsulation is performed by firstly attaching the tool to one outer lid and then overlapping the one outer lid with the other outer lid and thereafter encapsulating (connecting) the pair of outer lids.

Description

  Regarding a cardboard box (such as a packaging box) having a pair of outer lids, it relates to a “sealing tool that seals a pair of outer lids in a connected manner”.

This sealing tool is formed by connecting a lower presser and an upper presser via a support.
There are many conventional sealing devices in this configuration, but there are no appropriate ones such as forms and usage methods. Furthermore, there is nothing that can be sealed in a stable state.

  The present invention is that “the lower presser foot” “has a certain length (length width)”.

  For example, it is difficult to seal a pair of outer lids in a stable state (a state where the back cover is not back-up) or a flat, tightly closed state, as disclosed in Patent Documents 1 and 2.

JP 11-59663 A 4-74619

(1) To obtain a sealing tool in the form of connecting a pair of outer lids.
(2) To obtain a sealing tool that can be attached to a portion near the center of the opening or an appropriate portion of the opening.
(3) A firm state or a flat state, that is, a state in which the pair of outer lids do not flutter at the joint, or a state in which the closed lid does not float (hereinafter, this state is referred to as a “stable state”). To obtain a seal that can be sealed.

Regarding the sealing device in which the lower presser and the upper presser are connected via the support column, the lower presser has a “certain length (hereinafter also referred to as a length width or a passing width)”.
“Constant length” refers to a length or width suitable for connecting (sealing) a pair of outer lids in a substantially stable state.

  The operation for sealing is "attach (first attach to one outer lid, then fold with the other outer lid)", and then "set (connect a pair of outer lids in a sealed state)" The operation (procedure) is generally performed in two stages.

  The pair of outer lids can be connected (sealed) in a firm state or a stable state.

It is a figure which shows the process sealed about FIG. It is a figure which shows one of the sealing tools of this invention. It is a figure which shows one of the sealing tools of this invention.

In describing the present invention, the meanings of top, bottom, vertical, horizontal, left, right, inside, outside, back, and front are properly used while viewing the figure.
The packaging box is described with a cardboard box in mind.
A cardboard box has a width surface and a length surface. Mainly expressed in terms of viewing from the width side (width side).
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, the joint between the pair of outer lids is expressed in the form of a vertical line.
The sealing tool has a certain length and width in the lower presser, that is, the sealing tool has a width and a length, and has side surfaces on the width side and the length side.

The fixed length is the length that allows the inside of the pair of outer lids to be passed and pressed, and is the length or width that can be sealed so that the pair of outer lids do not break at the joint or do not float at the joint. .
In other words, the length or width sufficient to obtain a state in which the joint is not backlashed (that is, can be tightly sealed) is referred to as a certain length width.
However, in order to seal (connect) the pair of outer lids in a state where they are not backed up, it is a precondition that the interval between the lower presser and the upper presser and the strength for holding the presser are appropriate.
By the way, even if the interval between the lower presser and the upper presser and the strength of the presser foot work properly, it is difficult to obtain a state where the presser foot does not flutter. Combined with having a success.

The constant length width is a width in a relative relationship with the width (lateral width) of the outer lid. The length width may be arbitrarily determined according to the size of the lid width (lateral width).
For example, in the case of a corrugated cardboard box (a mandarin orange box close to the opening) having a width of 38 centimeters and a width of 30 centimeters, that is, when the width of one outer lid is 15 centimeters, A certain result was obtained with a width of about 10 cm, and a good (reliable) result was obtained with about 16 cm.
The longer the width, the better, but it should be set with consideration for entanglement with the operability, i.e., the edge of the inner lid and the inner wall of the box when it does not rotate. It is important to do.
Incidentally, 3-4 centimeters is sufficient for the width of the upper presser (width for holding the left and right outer lids) with respect to the length width (passing width) of the lower presser described above.

This sealing tool is used as a basic operation for sealing "first attach to one outer lid, then mate with the other outer lid", and then "set, that is, a pair of outer lids. It is based on the operation (procedure) of the two steps of “join and seal”.
How to rotate and use it is arbitrary, but in this document, except for exceptions, it is explained how to rotate clockwise to seal and rotate counterclockwise to open.

This will be described below with reference to the drawings.
From the difference of the sealing method, it classify | categorizes and demonstrates to form 1, form 2, and form 3.

Mode 1 (FIGS. 1 to 7) will be described.
In the first mode, “at first, attach to one (for example, the right) outer lid”, “take the shape to push the lower presser to the other (left)”.

Referring to FIG.
FIG. 1A is a perspective view.
FIG. 1 (2) is a side view as seen from the width side (A direction).
FIG. 1 (3) is a side view seen from the length side (B direction).

  The sealing tool shown in Fig. 1 (1) has an upper presser as viewed from the width side, as shown in Fig. 1 (2), extending from the upper end of the column to one side (left or right). As seen from the length side, as shown in FIG. 1 (3), it extends from the upper end of the column in both directions (left and right).

In this document, with regard to the sealing tool, the side “first attached to one outer lid” will be referred to as “attachment side”, and the side “sending out to the other party” will be referred to as “sending side”.
In the case of FIG. 1 (1), the side (b1) facing away is called the “attachment side”, and the side (b2) facing forward of the hand is called the “sending side”.

FIG. 2 will be described.
2 (1), (3), and (5) are views showing a process of sealing the sealing tool shown in FIG.
2 (2) is the state of FIG. 2 (1), FIG. 2 (4) is the state of FIG. 2 (3), and FIG. 2 (6) is the state of FIG. 2 (5) as viewed from the width side of the cardboard box. FIG.

FIG. 2 (1) is a diagram showing a state where the device is attached to one (right) outer lid. In this state, the lower presser is presented to the other party (left side).
FIG. 2 (3) is a view showing a state in which the other (left) outer lid is folded on the inserted lower presser and the pair of outer lids are folded into a flat state.
FIG. 2 (5) is a view showing a state in which the upper presser is operated (rotated) and the pair of outer lids are connected (sealed).
That is, in FIG. 2, the upper presser is operated to pass over the pair of outer lids (passing presser), and at the same time, the length direction of the lower presser (direction in which the length width extends) It is a figure explaining the process turned to the direction which crosses the joint line of an outer cover.

  The above process (or procedure) is for the purpose of passing and holding the inside of the pair of outer lids with the length of the lower presser and for setting the length sideways.

FIG. 3 will be described.
FIG. 3 shows an example in which an ear (h) is attached to the upper presser for the one shown in FIG.
When the upper presser is rotated from the state shown in FIG. 2 (3) to the state shown in FIG. 2 (5), the upper presser often sticks to the edge of the outer lid of the other party and is difficult to operate.
As a measure to cope with this, it is advisable to put an ear on the upper presser as shown in FIG.
Ears should be swayed (ribbon-shaped) without sticking to other boxes. Also, when operating the upper presser, keep the handle freely, and when the upper presser is passed over the other party's outer lid, it will be pulled back without sticking to the edge of the other party's outer lid. It can function as a “pass (or bridge)” for that purpose.
The above-described ear is an example, and any ear may be used, and “a cord” may be attached instead of the ear. Incidentally, if it is provided as a “knob” for facilitating the rotation operation, it is also possible to simply devise the shape such as making a hole in the upper presser itself or cutting out the periphery.

FIG. 4 will be described.
Since this sealing tool is “assuming that the lower presser has a certain length and width”, the lower presser sticks to the edge of the inner lid when opening it, when returning from the horizontal position to the vertical position. May become unopenable.
FIG. 4 illustrates an example of the countermeasure.

FIG. 4 (1) is the same as that shown in FIG. 1 (1).
FIG. 4 (2) is a perspective view of the movement of the lower presser in a state of being attached to the cardboard box (the outer lid) as seen from above in a plan view.
A vertical line (y) is a joint of a pair of outer lids. The horizontal line (x) is the edge of the inner lid.
m1, m2, and m3 are diagrams showing the rotating motion of the lower presser.
When sealing, the lower presser attached in the state of m1 is set in the state of m3 (sealed state) through the state of m2. At this time, it does not stick to the inner lid.
When opening, the operation of returning from the state of m3 to the state of m1 (a state that can be opened) is performed.
In the course of this operation, when the m2 state is reached, the end (w) of the lower presser may stick to the edge (thickness) of the inner lid and may not return to the m1 state.
As a countermeasure, at least for the portion near the end of the lower presser, a measure such as removing the taper of the lower (outer) corner (side) of the lower presser is required.
That is, it is required to slide between the inner lid and the outer lid. Incidentally, FIG. 4 (3) shows the shape (tapered shape).
However, it is not always useful when the distance between the pair of inner lids is sufficiently wider than the length of the lower presser.

FIG. 5 will be described.
FIG. 5 (1) is an extension of FIG. 1 (1), in which a spring mechanism is provided on the outer lid (thickness) so that the outer cover fits perfectly.
FIG. 5A is a perspective view.
FIG. 5 (2) is a side view as viewed from the length side (B direction), and shows a state where a spring mechanism is provided on the lower side (back side) of the lower presser.
FIG. 5 (3) is a perspective view of the lower presser (back side), and shows a state in which a leaf spring is provided.
The leaf spring shown in the figure has one end fixed to the lower presser and the other end opened (slidably moved).

In the case where the distance between the upper presser and the lower presser is fixed (for example, the one shown in FIG. 1), the fitting frame is either tight or loose, and it is difficult to expect that it is just right. Even if there is a slight difference in the thickness of the outer lid, and even if there is a difference in hardness (paper quality), it is desirable to have a spring mechanism.
The spring mechanism shown in FIG. 5 serves to elastically adjust the height width of the column (ie, the interval between the upper presser and the lower presser) in the portion interposed between the upper presser and the lower presser. is there.
Incidentally, the spring shown in FIG. 5 is shown as an example, and may take any form. In addition, all the sealing tools shown by this application can improve practicality by having a spring.

FIG. 6 will be described.
FIG. 6 is a view in which the position of the column is changed as compared with FIG.
FIG. 6A is a perspective view.
FIG. 6B is a side view seen from the position A on the width side.
FIG. 6 (3) is a side view seen from the C position on the width side.
In FIG. 6 (2), there is no lower presser (no upper presser) on the insertion side (left side of the column).
In FIG. 6 (3), there is a lower presser on the insertion side (left side of the support column).

  As shown in FIG. 6 (3), the one shown in FIG. 6 presents a lower presser on the insertion side (left side) as in the shape shown in FIG. 1 (2). Therefore, it can be used in the same manner as shown in FIG. 1 with the shape shown in FIG.

FIG. 7 will be described.
FIG. 7 explains that it can be used in the same manner as shown in FIG. 1 with the shape shown in FIG. 6 (3).
FIG. 7 (1) is a diagram showing a state where the sealing device shown in FIG. 6 is attached to one (right) outer lid in the shape shown in FIG. 6 (3).
FIG. 7 (2) is an enlarged partial view of the state of FIG. 7 (1) (the state attached to the edge of the right outer lid).
That is, as shown in FIG. 7 (3), the lower presser can be pushed out to the other party (left side) and the other party's outer lid can be overlapped.

  FIGS. 6 and 7 illustrate that the state or form is not questioned as long as the lower presser can be pushed out to the other side (the feeding side) when attached to one outer lid. is there.

The form 2 (FIGS. 8 to 10) will be described.
In the second mode, “First, attach it to the outer lid of one side (for example, the right side)” and “take out the form to push the upper presser to the other side (left side)”.

FIG. 8 will be described.
FIG. 8A is a perspective view.
FIG. 8B is a side view seen from the width side (A direction).
FIG. 8 (3) is a side view seen from the length side (B direction).

  The sealing tool shown in FIG. 8 (1) has a lower presser as viewed from the width side, as shown in FIG. 8 (2), extending from the lower end of the column to one side (left or right). As seen from the length side, as shown in FIG. 8 (3), it extends from the lower end of the column in both directions (left and right).

FIG. 9 will be described.
FIGS. 9 (1), (3), and (5) are diagrams showing a process of sealing the sealing tool shown in FIG.
9 (2) is the state of FIG. 9 (1), FIG. 9 (4) is the state of FIG. 9 (3), and FIG. 9 (6) is the state of FIG. 9 (5) as viewed from the width side of the cardboard box. FIG.

FIG. 9 (1) is a diagram showing a state where it is attached to one (right) outer lid. In this state, the upper presser is presented to the opponent (left side).
FIG. 9 (3) is a diagram showing a state in which the outer lid of the other party (left side) is folded and the upper presser that has been pushed out is folded over to hold the pair of outer lids flat.
FIG. 9 (5) is a view showing a state in which the upper presser is operated (rotated) and a pair of outer lids are connected (sealed).
That is, in FIG. 9 (5), the upper presser is operated so that the length direction of the lower presser (direction in which the length and width extend) is directed to the direction crossing the joint line of the pair of outer lids (lateral direction). It is a figure.

  The above process (or procedure) is for the purpose of passing and holding the inside of the pair of outer lids with the length of the lower presser and for setting the length sideways.

FIG. 10 will be described.
FIG. 10 is a supplementary explanation of the sealing tool shown in FIG.
In the stage where the sealing device is “attached to the outer cover of one side (for example, right side)”, the lower presser is on the side where all the parts are attached. Therefore, when sealing, that is, when the lower presser is turned inside (lower side) of the other party's outer lid, it often sticks to the edge (step) of the other party's outer lid.
Further, since the lower presser has a length and width, when opening, that is, when the lower presser is rotated, the portion near the end often sticks to the edge of the inner lid.
FIG. 10 shows the countermeasure.

FIGS. 10 (1) and 10 (2) are perspective views of the movement of the lower presser in a state of being attached to the cardboard box (outer lid) as seen from above in a plan view. A vertical line (y) is a joint of a pair of outer lids. The horizontal line (x) is the edge of the inner lid. m1, m2, and m3 are views showing the movement of the lower presser rotating.
FIG. 10 (1) illustrates the movement when sealing.
When trying to rotate the sealing tool attached in the state of m1 clockwise, the side (w) of the lower presser bumps into the step with the outer lid of the other party (left).
FIG. 10 (2) illustrates the movement when opening.
While turning counterclockwise and returning to the state of m1 from the state of m3, when approaching the state of m2, the part near the end of the lower presser (w) will stick to the thickness of the inner lid.

FIGS. 10 (3) and 10 (4) are diagrams showing the shape of the lower presser devised as the above countermeasure.
FIG. 10 (3) is a perspective view. The portion indicated by S is the position of the column that becomes the center of rotation.
FIG. 10 (4) is a side view seen from the width side (A direction).
When sealing in the clockwise direction, as shown in Fig. 10 (4), crawl the other party's outer lid from below so that it does not stick to the edge of the other party's outer lid. It should be in the form of raising.
As shown in Fig. 10 (4), the side of the side and the tip end are cut away so that the edge of the inner lid does not stick to the edge of the inner lid when opened in the counterclockwise direction. It is good to keep it in a state (that is, in a tapered shape).

  The shapes (shapes) shown in FIGS. 10 (3) and 10 (4) are shown as an example. In short, it is possible to make any shape or design after recognizing the above-mentioned problems.

Mode 3 (FIGS. 11 to 15) will be described.
In the third mode, “at first, attach to one outer lid”, “take the shape of the length of the lower presser toward the other side”.
That is, the lower presser takes a shape in which the length direction is always directed in the direction (lateral direction) intersecting the joint line (vertical line) of the pair of outer lids.

FIG. 11 will be described.
FIG. 11 has a spring mechanism similar to that shown in FIG. However, in the case of FIG. 5, the upper presser and the lower presser are fixed, whereas in the case shown in FIG. 11, the upper presser rotates with respect to the lower presser (that is, the spring). The device is not fixed to the lower presser).

  Therefore, the upper presser can be rotated to appropriately take the state shown in FIG. 11 (1) or the state shown in FIG. 11 (2).

11 (1), (2), and (5) are perspective views.
FIG. 11 (3) is a side view of FIG. 11 (1) viewed from the width side (A direction).
FIG. 11 (4) is a side view of FIG. 11 (2) viewed from the length side (B direction).
FIG. 11 (5) is a view of FIG. 11 (2) viewed from the back side.

FIG. 11 (1) shows the posture taken at the stage of attachment to one outer lid. FIG. 11 (2) shows the posture taken at the stage of connecting (sealing) a pair of outer lids.
It can be sealed by rotating from the position shown in FIG. 11 (1) to the position shown in FIG. 11 (2) around the column as a shaft, that is, rotating from e1 to e2. How to use (that is, how many angles are to be rotated or moved) may be arbitrarily determined as appropriate. It is good to keep it from turning more than necessary.

FIG. 12 will be described.
FIG. 12 illustrates FIG.

12 (1), (2), and (3) show an example in which a stopper is provided for the lower presser constituting FIG.
When the upper presser is rotated, the lower presser often slides (rotates) in conjunction with it, so that a function or form as a stopper is required so that the lower presser does not rotate.
The stopper (D5) shown in FIG. 12 (1) is a line-like ledge that is sandwiched between the joints (gap) of the pair of outer lids.
FIG. 12 (2) is a side view of FIG. 12 (1) viewed from the width side (A direction).
FIG. 12 (3) is a side view of FIG. 12 (1) viewed from the length side (B direction).

  In order to form a stopper, as described above, there are a method using a seam of a pair of outer lids and a method using holes (holes) in the thickness of the outer lid (cardboard). The method may be arbitrarily determined. The form of the stopper may be arbitrarily determined.

If the stopper does not have a function or form, the lower presser may be circular so that it does not interfere with the lower presser even if it slides in conjunction (rotates). However, in that case, it is important that the shape is a circle having a certain length and width. Thus, even in the case of a circular shape, the interpretation of “the lower presser has a certain length and width” as used in the present invention is taken.
There is also a proposal for a method in which the cardboard box itself has a stopper shape, or the inner wall surface of the cardboard box is used.

12 (4), (5), and (6) illustrate the spring mechanism (D4) that constitutes FIG.
FIG. 12 (4) is a view (perspective view) in which the metal wire is bent and the upper presser foot (D1), the support post (D2), and the spring device (D4) are integrally formed.
FIG. 12 (5) is a side view of FIG. 12 (4) viewed from the A direction.
FIG. 12 (6) is a side view of FIG. 12 (4) viewed from the B direction.
Since what is shown in FIG. 12 (4) is an integrated body, both the support and the spring mechanism are linked (rotated) together with the upper presser, but only the upper presser is rotated, or the upper presser The configuration may be arbitrarily set, such as the shape of only the column and the column rotating. Incidentally, what is shown in FIG. 12 (4) is shown as an example, and may take any form.

FIG. 13 will be described.
13 (1), (3), and (5) are diagrams showing a process of sealing the sealing tool shown in FIG.
13 (2) is the state of FIG. 13 (1), FIG. 13 (4) is the state of FIG. 13 (3), and FIG. 13 (6) is the state of FIG. 13 (5) as viewed from the width side of the cardboard box. FIG.

FIG. 13 (1) is a view showing a state in which the present sealing tool is attached (fitted) to the edge of one outer lid (for example, the right side).
In the case of this sealing tool (sealing tool shown in FIG. 11), the length of the lower presser (direction in which the length and width) are extended toward the other party at the stage of attachment.
FIG. 13 (3) is a diagram showing a state in which the other (left) outer lid is folded on the inserted portion (lower presser), and the pair of outer lids are folded into a flat state. .
FIG. 13 (5) is a diagram showing a state in which the upper presser is operated (rotated) and the pair of outer lids are coupled (sealed).

FIG. 14 will be described.
Similarly to the case of FIG. 11, FIG. 14 is also attached with the length direction of the lower presser (the direction in which the length width extends) facing the other side at the stage of attachment to one outer lid.

  In the case of the one shown in FIG. 11, the pair of outer lids are connected (sealed) by “rotating the upper presser”, whereas in the case shown in FIG. A pair of outer lids are connected by sliding. Except for this point, the sealing process is the same as that shown in FIG.

  The upper presser (D1) shown in FIG. 14 is composed of a fixed piece (D11) and a movable piece (D12). When viewed from the length side (B direction), one side (left or right) ), Or by shifting (or sliding) the movable piece, it can be formed to extend from the upper end of the column to both (left and right).

FIG. 14 (1) is obtained by combining (assembling) the movable piece (D12) shown in FIG. 14 (3) with the fixed piece (D11) of the upper presser shown in FIG. 14 (2). Incidentally, FIG. 14 (3) is the figure which looked at the movable piece from the back side. 14 (1) (2) (3) (4) are perspective views.
In addition, although the movable piece shown in FIG. 14 is a thing of the form which slides to right and left, it is good also as a thing of the form of rotating. Incidentally, those forms or configurations may be arbitrarily determined.

FIG. 15 will be described.
FIG. 15 shows a shape in which the upper presser rotates with respect to the lower presser similarly to the one shown in FIG. 11.
FIG. 15 shows a series of two.
FIG. 15 (1) shows a state in which the upper presser is directed to one side (right side), that is, a state at the time when the upper presser is attached to one outer lid.
FIG. 15B shows a state in which the upper presser passes and holds the left and right (a pair of) outer lids, that is, a posture when the pair of outer lids are connected (sealed).

  FIG. 15 shows one of application examples shown in FIG. 11, that is, when the upper presser (only) is rotated.

  FIG. 15 also shows an example in which measures are taken so that the lower presser does not slide when the upper presser is rotated.

  The following are general supplementary items.

The above-described figures are intended to insert a support column through the joint between the pair of outer lids. In the examples (however, except for FIG. 14), the support rods were # 16 (2.6 mm diameter) wires.
If there is no gap between the joints of the pair of outer lids or a gap cannot be created, appropriate notches that allow the support to be inserted can be provided on one or both edges of the left and right (pair) outer lids. good. If a cutout is provided, a thick support (shaft) with a space can be used.

It supplements about the function or role of the upper presser.
The original role of the upper presser is to serve as a handle for passing and holding the left and right (one pair) outer lids and moving (rotating or sliding) the lower presser. Incidentally, the shape may be set arbitrarily.
According to the feature of the present invention ("the lower presser has a certain length and width"), an index for knowing which direction the length of the lower presser (the direction in which the width extends) is suitable. It is also important to become.
That is, in order to know whether it is in a sealed state or in a state where it can be opened, it is determined by the state (shape) of the upper presser or is recognized by a sign attached to the upper presser.
Incidentally, the shape and the sign may be arbitrarily set. Further, rules for discrimination or recognition may be arbitrarily determined.

  The upper presser is required to be as thin as possible so as not to hinder the handling of the load, that is, to prevent the load to be piled up.

  The present invention is mainly intended for cardboard boxes, but can also be used for boxes other than cardboard boxes having the same form (referred to as packaging boxes in this document).

  The sealer is not limited in terms of material and material throughout. As long as necessary functions are not impaired, the shape, contour, design, size, form and the like may be arbitrarily determined.

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