Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to articles, particularly postcards for photographs, having an adhesive surface.

(b) Prior Art Currently, various types of FC postcards are known. An ordinary postcard, one side of which is used for writing addresses and the other side for viewing correspondence, is used for normal communication purposes. For those who go on vacation, there are various types of postcards that have a photo on one side. The other side of the postcard is for short correspondence and a unique name and address. A typical example of this would be a photograph of an interesting local landscape. Or perhaps, many of the small images of local landscapes are captured.

And this is especially suited for large postcards.

Such postcards allow vacationers to send photos of their vacation destinations and other destinations to friends and relatives.

However, they can only send general scenes, whereas friends and relatives often want photos of the sender that include family members. Currently, the only way to send photos is by letter, which is more expensive and time-consuming. Also, such postcards are inconvenient from the producer's standpoint. This is because a variety of different postcards must be produced in different locations, and a variety of demand quantities for each postcard must be predicted.

Various suggestions have been made regarding how to send photos by mail. These methods are usually quite complex, expensive to make, and difficult to use.

Some of the ideas are to securely store photos,
It cannot be protected.

Applicant's first U.S. patent application discloses a postcard to which photographs and other items can be affixed. There is a support sheet with removable panels that can be selectively removed so that photographs of various sizes and other items can be attached to the postcard.

Although this postcard allows photos to be sent by mail, it does not fully protect the photos, and having a removable panel is quite cumbersome.
It is expensive.

GPl Problems that the invention aims to solve Postcards that send photos by mail must protect the photos reliably and must be sent in a way that anyone can use. Furthermore, it must be able to be mass-produced.

In the present invention, a postcard is used to send by mail a sheet-like article in which one side of the sheet-like article is visible. ing. The postcard consists of: a sheet-like member made of a relatively hard material and supporting such an article; a transparent sheet attached to the edge portion of the corresponding sheet member along one edge portion; and a transparent sheet attached to one side of the transparent sheet;
an adhesive layer, wherein the first and second adhesive layers face each other; the first and second adhesive layers are provided between the first and second adhesive layers, and the sheet member and the transparent sheet are connected to each other; A companion protective sheet for separating the postcards from each other, which is missing the aforementioned edge portion, and which includes a tab extending from the edge opposite to the aforementioned one edge over the entire width of the postcard. In use, this protective sheet is removed and a sheet-like article is installed between the sheet-like member and the transparent sheet, and is attached to the first and second adhesive layers. and the article χ installation;
And to protect, the exposed part of the first adhesive layer is adhered to the corresponding part of the second adhesive layer, and each sheet-like member, transparent sheet and protective sheet is the same for the gold pile of the postcard. It is designed to have some height.

The postcard is the size of a normal postcard, for example, about 15.2cm.
m (6") width and approximately 10.8 (1m (4-"/4")
) can have a height of The edge part and knob to which the sheet member and transparent sheet are attached are as follows:
It can be placed along the long side of the postcard. On the other hand, in some cases, the edge portion attaching the sheet-like member and the transparent sheet is provided along the short side of the postcard, and the tab also extends along the opposite short side. Sometimes it's better to do so.

Postcards according to the invention are designed to be easy, inexpensive, and mass-produced. Various postcard elements can now be made from elongated strips of material. This is especially useful for making postcards.

In another aspect of the invention, a method of making a postcard for mailing a sheet-like article with one side of the article visible is presented. The method consists of the following: (11) Coat one side of the sheet-like member with an adhesive to form a first adhesive layer; (1) Cut the sheet-like member to one side of the postcard size. (iii) Coat one side of the bright sheet with an adhesive to form a second adhesive layer: θV) Second adhesive Attach a protective sheet to the layer; (v
) Cut the transparent sheet and the protective sheet to form a strip having a width equal to the above dimensions of the postcard and the depth of the tab; (vl) Cut along the edge of each strip of the protective sheet and the transparent sheet. cut out one edge of the transparent sheet, and cut out an amount of transparent sheet equal to the depth of the tab along the opposite edge of each strip; Attach the band material of each sheet-like member, the transparent sheet, and the band material of the protective sheet by fixing it to the edge portion of the sheet-like member; A synthetic strip consisting of a portion of a transparent sheet is cut to a length equal to the other required dimension of the postcard to produce a product postcard.In this way, the method according to the invention can be applied to the postcard according to the invention. It offers a simple and economical manufacturing method.

The postcard according to the invention allows the person using it to send postcards with, for example, pictures of themselves, their family and friends, instead of the usual mass-produced landscape postcards. The transparent sheet ensures that photographs and other items are securely retained. It's a box, and the corner of the photo is used to sort the mail, ensuring that the photo won't be torn off and damaged. transparent sheet,
The provision of an adhesive layer on both sheet-like members ensures that the friend photo is held securely. Additionally, if desired, the adhesive can be a pressure-sensitive adhesive so that the photo can be peeled off the postcard.

In this way, it not only allows the recipient of this postcard to create his own postcard, but also allows the recipient to remove the postcard and store it in an album or other suitable location. That's what I do.

The first adhesive layer can be any suitable adhesive that allows the protective sheet to be removed and holds the article in place. It does not need to be transparent.

The second adhesive layer is desirably transparent and has the same adhesive properties as the first adhesive layer. However, the second adhesive layer can also be tinted, and for some purposes this may even be preferred.

To facilitate the use of postcards, the protective sheet, ie the support material, should adhere more strongly to the second adhesive layer. To achieve this, it is desirable to apply different coatings on both sides of the protective sheet. The protective sheet is the second
It must be able to adhere to the adhesive layer fairly well and be easily peelable. On the other hand, as for the first adhesive layer, it is desirable that it adheres very lightly to the protective sheet. In this manner, the user can lift the transparent sheet and the protective sheet using the tab on the protective sheet. Then place the photograph on top of the first adhesive layer. The protective sheet is removed and a transparent sheet is placed over the photograph and first adhesive layer. If electricity is needed under the transparent sheet, it can be removed by hand.

Although it is desirable that the postcard packet include the necessary instructions for use, with the above preferred structure of the postcard, it is almost self-evident how the postcard should be used. When a user opens a postcard, it is natural for the user to lift the protective sheet together with the transparent sheet. In other words, there is little tendency for the user to first peel off the protective sheet from the transparent sheet. Furthermore, by allowing the protective sheet and the sheet-like member to be easily separated, the transparent sheet is prevented from being damaged. If the two are strongly adhered, when the transparent sheet and protective sheet are lifted, the transparent sheet will be strongly bent, causing cracks, cracks, and other damage.

(E) Embodiments In order to better understand the present invention and to show how it is actually used, embodiments of the present invention will be described with reference to the drawings.

In the figure, postcards are generally marked with the symbol 1°C. 1st
In the figures, the postcard is shown at approximately 2"/2 in size; in the other figures, the height of the postcard is shown to scale.

For clarity, the depth, or thickness, of the postcard is shown enlarged in Figures 2 to 7 so that the different layers can be clearly shown.

The μ postcard 1 has a sheet-like member 3, which is made of normal cardboard for postcards. It is the subject of the postcard. As shown in more detail in FIGS. 2 and 3, an auxiliary transparent sheet 8 is attached to the sheet-like member 3 along its edge portion 14.

This will be explained in more detail below.

The first adhesive layer 6 is provided on the sheet member 3 and extends over the entire upper surface of the sheet member 3. The second adhesive layer 10 is provided on the corresponding surface of the transparent sheet 8. Both adhesive layers 6.10 consist of pressure-sensitive adhesives. A protective or supporting sheet 12 is provided to separate the adhesive layers 6, 10. It can be easily peeled off from the adhesive layers 6 and 1o, and it is preferable to use a material with a glossy finish.

The edge portion of the protective sheet 12 is missing, and the corresponding portions of the first and second adhesive layers 6, 10 are adhered to each other, thereby firmly attaching the transparent sheet 8 to the sheet-like member 3. As shown in FIG. 2, in this way, the edge portion 14 of the transparent sheet 8 is exposed to the opposing edge portion of the sheet-like member 3 and can be fixed by the action of the adhesive layers 6 and 10.

As shown in FIGS. 1 and 2, the protective sheet 12 has a rectangular knob 18. As shown in FIGS. This knob 18 postcard 1
It extends to the gold mine and has a uniform height, or depth. All the members of the postcard 1 are rectangular and have, in particular, the same width and the same height (their dimensions are shown in FIG. 2).

After all, postcard 1 can be produced relatively easily.

There is no need to make each component into a mold and then assemble them to finish the finished mesh. Alternatively, the sheet member 3, the transparent sheet 8 and the protective sheet 12 can be made into a strip shape. These are coated with adhesive layers 6, 10 and then assembled into a continuous strip having a cross-section as shown in FIG. This strip material can be cut into postcards of a suitable width.

This assembly method will be explained in more detail below.

The postcards shown in FIGS. 1 and 2 are normally supplied in an unfolded T-shape. To use the postcard 1, grasp the knob 1B and lift it together with the transparent sheet 8 and protective sheet 12. FIG. 2 shows a partially open situation. In this way, the transparent sheet 8 is peeled off and the first adhesive layer is exposed. At this time, the edge portions 14 and 16 maintain the connection between the sheet-like member 3 and the transparent sheet 8. The photograph indicated by 22 in FIG. 6 is then placed on the sheet-like member 3. The protective sheet 12 is then peeled off from the second adhesive layer 10, and it is exposed. The transparent sheet 8 is returned to its original position,
Postcard 1 is completed after it is gently stretched. Result photo 2
2 will be fixed to both the first and second adhesive layers 6 and 10. At the same time, the first and second adhesive layers 6, 10
0 outer peripheral parts are fixed to each other. As a result, the photograph 22, together with the sheet-like member 3 and the transparent sheet 8, becomes one solid structure. It is mailed like a regular postcard, preventing any damage to the photo 22.

Although various materials and dimensions for the postcard can be used, preferred dimensions and materials for one embodiment of the present invention will be described in detail.

For the sheet-like member 3, Kromecoat (Kro
12 point thick cardboard sold under the name mecote (registered trademark)), approximately 70#/ream (155)
'bs/ream)) is preferred. One side of this material is matte and the other side is glossy. The matte side can be preprinted to indicate address, name and other correspondence in the usual manner. The other side is relatively glossy and coated with the first adhesive layer 6. This side of the sheet-like member 3 is preferably coated with another color from the beginning, as shown at 4. Then, an adhesive layer 6 is provided and further pressure sensitive.

The transparent sheet 8 is made of polyester in a thin plate shape and has a thickness of approximately 0.
．． It has a thickness of 0.5 mm (2 mils). Transparent materials other than polyester can also be used.

This sheet is coated with an adhesive layer, which is pressure-sensitive and forms the adhesive layer 1 (l).The optical properties of the first adhesive layer 6 are not very important, but it is transparent. It is desirable that the second adhesive layer 10 is
Since it is placed on top of 2, it must be transparent. For certain purposes, it may be desirable for this second adhesive layer to be lightly colored.

The protective sheet 12 is approximately 29.5 #/ream (65) t) a/r
made from nine paper raw materials with 1 amount of eam). Both sides are coated with silicone. Prior to coating with silicone, it is desirable that the upper surface be preprinted with instructions on how to use the postcard and other information 21 as shown. This top surface is covered with a transparent sheet 8 and a second adhesive layer 10, so instructions for use and other information can be found on the postcard 1.
Even if it is closed, it can be read easily. As mentioned above, the protective sheet 12 is first lifted off the first adhesive layer 6. For this reason, facing the first adhesive layer 6 [
The coating facing the second adhesive layer 10 is desirably less adhesive than the coating facing the second adhesive layer 10. This results in a coating 24' on the lower surface of the sheet 12.
This can be achieved by providing a thickness χ thicker than the coating 23 on the upper surface. Alternatively, this can also be achieved by coating the two surfaces differently. In order to allow the protective sheet 12 to be easily separated from the sheet-like member 3, the tackiness of the coating 24 facing the first adhesive layer 6 should be very low. A greater adhesive force should be provided between the upper surface of the sheet 12 and the transparent sheet 8 so that a pulling action is required to separate the two members.

In terms of dimensions, each member is approximately 15.2 cIL (6
The sheet member 3 has a height of approximately 10.8 cm (4-1/4"). The height of the two adhesive layers 6 and 10 is also approximately 10.8 an (4-1/4
).The height of the edge portion 14.16 is approximately 0.6
cR("/4"), while the height of the knob 18 is approximately 1.3 cm ("/2"). The height of the transparent sheet 8 is 1, corresponding to the height of the sheet member 3.
0.8 cm (4-1/4"). However, as shown in the enlarged view of FIG. 6, the transparent sheet 8 is distorted by the photograph 22. The edge is pulled up towards the edge portion 14.16. To enable this, the overall height of the transparent sheet is slightly less than about 10.8C1K (4-5ζ'), for example 9. It can be increased by about 0.81al (l/32"). As a result of this effect, the lower edges of the sheet-like member 3 and the corresponding transparent sheet 8 are aligned at the same height.

Next, the steps of the postcard manufacturing method according to the present invention will be schematically shown, with reference to Figures 4, 5, 6, and 7. A cardboard material is coated with adhesive and then pressure sensitized. The intermediate liner box is then placed over the protective sheet 20 to protect the pressure sensitive adhesive. Next, the material is approximately 10.8 C3I
(4-”/4”) interval (or other appropriate interval)
and then wound into each core. As a result, each core is made of material 3 whose cross section is shown in Figure 4.
This results in a continuous strip of 0.00 drops. The sheet-like member 3 is protected by an intermediate liner or sheet 20 and is provided with a first adhesive layer 6.

Separately, a transparent sheet, ie, a thin plate material, is prepared.

This is again coated with adhesive and made pressure sensitive.

The upper surface of the material for the protective sheet 12 is printed in advance, if necessary. It is desired that this material be coated with silicone on both sides, with the lower side having a different coating that will come off more easily than the one outlined above.

Next is the adhesive layer? For protection, the material of a protective sheet 12 is attached to the material of the transparent sheet 8.

This material is again cut into continuous strips.

However, this material is cut at intervals equal to the nine intervals at which the sheet-like member 3 is cut plus the height of the knob 1B. The height of the sheet member is approximately 1
0.8 t:x (4-1/4") and the height of the knob is approximately 1.5 crn (l/x"), this material is 12.1 Cal (4-3/ FIG. 5 shows a cross-section of the resulting strip. Each strip has a bottom section forming the protective sheet 12, and the end section is A transparent sheet 8 with a second adhesive layer 1 (1') therebetween. This strip is generally designated by the number 32. Again each strip is wound around a separate core (not shown). In FIG. 6, each strip 32 has a protective sheet 12 portion,
The second adhesive layer 10 is cut off in a rough manner. First, the edge portion of the transparent sheet 8 along with the corresponding adhesive layer 10 is cut off by 5Vc as shown at 34. This cut out part is for the reason explained below.
It has a slightly smaller height than the knob 18. Also 3
As shown at 6, one edge portion of the adhesive sheet 120 is cut out and the adhesive layer 10 is applied. This cut out part is about 0.64M1l (
The resulting modified nine-strip material is designated by the symbol 32A.

The strip material 30.32A is now ready for bonding. The intermediate liner and protective sheet 20 are removed and discarded. The two strips 30.degree. 32A are removed one after the other, and the protective sheet 12 is adhered to the first adhesive layer 6. At the same time, the edge portions 14, 16 of the sheet-like member 3 and the transparent sheet 8 are pressed together and permanently fixed to each other by the exposed nine portions of the adhesive layer 6.10. As shown in FIG. 7, one knob 18 is the protective sheet 1.
It remains as an extension of 2. As mentioned above,
The cutting height of the edge portion of the transparent sheet 8 is smaller than the height of the knob 18, so the transparent sheet 8
protrudes from the sheet member 3 by the amount indicated by 19. This amount must be sufficient to align the edges of member 3 and transparent sheet 8 when the photo is attached.

In this way, a continuous strip is obtained, designated by the number 40, the cross-section of which is shown in FIG. It is then cut to a length corresponding to the width required for the postcard. It is preferably cut to about 6".

The present invention is described for a conventional rectangular postcard, with the top and bottom edges being the long edges of the postcard and the short edges being the horizontal edges.

In the above-described embodiment, the transparent sheet is adhered to the sheet-like member along the upper edge of the postcard. It will be appreciated that these two members may be attached along any edge of the postcard, and that other arrangements of the postcard are possible.

Alternatively, the short sides of the postcard may form a t-form with the top and bottom of the postcard. The above-described method for producing postcards can be similarly applied to such arrangements by appropriately changing the dimensions used.

The postcard of the present invention and the method of making it are inexpensive and well suited for mass production. The various parts of the postcard can be made of strips, which can be attached to each other and worn by companions as needed. The final step in the manufacturing process is to cut the binding material of the product to a predetermined length. It is much easier and simpler to handle continuous strips of material than to handle many individual rectangular members in various assembly processes.
