Description

  The present invention relates to a postcard with lottery, and particularly to a postcard with lottery.

  2. Description of the Related Art Conventionally, as post-crimp postcards in which notification information cannot be viewed by others, two-fold and three-fold postcards are widely known. As a two-fold form, it is a two-fold postcard that can be separated from the crease line by a perforation line. On one side of the spread, for example, items such as proof and request are displayed, and on the other side, the above items are displayed. There are known concealed postcards that are displayed as stickers, folded so that these display parts face each other, and pasted on a display surface of the overlapping surfaces by a pre-formed peelable adhesive layer (for example, patents) Reference 1). As a tri-fold form, a mail form used for a secret postcard or the like in which a weak adhesive layer is formed on the entire surface of the base material to be adhered cannot be peeled off on the side edge of the adhesive surface on which secret information is printed. A security mail form provided with a strong adhesive layer, an opening perforation and a corner cut is known (for example, see Patent Document 2).

  However, since the above-mentioned two-fold and three-fold crimped postcards are composed of a single sheet in which each piece of paper is connected so that the size of the postcard is folded in two or three. When this form is applied to a lottery postcard with a lottery number, such as a New Year postcard with a New Year's card or a lottery card (Kamoru), the piece of paper must be independent. There is a problem that it cannot be applied to lottery postcards due to restrictions imposed by government-related postcards. To apply to lottery postcards, each piece of paper must be independent. On the other hand, as a crimped postcard made up of independent paper pieces, a concealment is formed such that a sheet piece is detachably laminated on one side of the postcard body via an adhesive layer, and concealment information is revealed by peeling the sheet piece A postcard is known (for example, refer to Patent Document 3).

However, the concealment postcard of Patent Document 3 is composed of an adhesive layer composed of a mixture of a wax emulsion and a vinyl acetate acrylic copolymer emulsion, and the vinyl acetate acrylic copolymer emulsion is added to adjust the adhesive strength of the adhesive layer. However, when the blending ratio is small, the adhesive strength is weakened, and there is a problem that the postcard body and the sheet piece may be separated during delivery.
On the other hand, by using a postcard with lottery, the recipient sees the written information and keeps it at least until the lottery date. For example, if it is product information, there is a need from the seller, manufacturer, etc. who can improve the continuity of the sales promotion effect of the product, and the lottery with high confidentiality There was a demand for the development of postcards.

  Next, the material used for the postcard with lottery 1 of the present invention will be described. High quality paper, card paper, coated paper, clay coated paper, kraft paper, etc. can be used for the postcard main body piece 2 and the concealment paper piece 3, and the basis weight and size are government-made postcards with lottery numbers of winning and losing Can be selected arbitrarily within the scope of the provisions on Although it will be described later that the postcard body piece 2 and the concealment paper piece 3 are made of the same material, it is preferable because the postcard body piece 2 and the concealment paper piece 3 can be manufactured using a wide sheet in which the postcard body piece 2 and the concealment paper piece 3 are arranged together and the number of processes can be reduced. .

The pressure-sensitive adhesive used for the weak pressure-sensitive adhesive layer 4 is a pressure-sensitive type, and is adjusted so as to facilitate adhesion and re-peeling of the adhesion surface. Conditioners, additives and the like are mixed in the following proportions.
(1) Adhesive main agent 100 parts by weight (2) Adhesive strength modifier 10 to 100 (preferably 10 to 50) parts by weight of acicular substance 0 to 50 (preferably 5 to 30) parts by weight of fine particulate substance When both substances are mixed 10 to 100 parts by weight (3) Additive wax 0.01 to 20 parts by weight Ultraviolet absorber Trace amount Defoaming agent Trace amount Defoaming aid Trace amount (4) Emulsifying component Water 100 to 500 (preferably 200 to 300) parts by weight Emulsifier 0.5 to 2 parts by weight Resin 1 to 50 parts by weight

  Examples of the resin used for the adhesive main agent include natural rubber (NR), esterified natural rubber, styrene butadiene rubber (SBR), chloroprene rubber, polyvinyl acetate, polymethyl methacrylate (PMMA), or the like. A mixture is mentioned. In mixing these pressure-sensitive adhesives, the adhesiveness between the pressure-sensitive pressure-sensitive adhesives can be maintained higher than the self-adhesiveness while maintaining the self-adhesiveness between the pressure-sensitive adhesives by appropriately adjusting the mixing ratio. Preferably, polymethyl methacrylate or styrene butadiene rubber is added to natural rubber, which has a high property of developing self-adhesiveness between pressure sensitive adhesives under pressure, in order to enhance adhesion to the substrate, that is, the anchor effect. Is mentioned. Rather than using polymethylmethacrylate alone, it is better to mix it with another adhesive main agent. As such an adhesive main agent, a fine particle having a particle diameter of about 0.1 μm to 3 μm is usually used.

The adhesive strength adjusting agent is mixed in order to adjust the adhesive strength of the adhesive main agent, and an acicular material, a fine particulate material, or a mixture thereof is used.
<Acicular substances>
The needle-like substance may be either an inorganic substance or an organic substance, and it may be any shape as long as the shape is substantially needle-like, and is arbitrarily selected from those having various forms such as flat, spiral, and scale-like. Needle-like substances are particularly suitable. The needle-like substance preferably has an average length of 10 μm to 20 μm and an average diameter of about 0.2 μm to 0.5 μm. The needle-shaped substance preferably has an apparent specific gravity of 0.05 to 0.6 in order to reduce sedimentation when the pressure-sensitive adhesive is made into an emulsion and used as a coating agent, and also considers printing processing and NIP suitability. Then, the elastic modulus of the acicular substance is preferably 10,000 kg / mm ^{2 to} 40000 kg / mm ² . Examples of such acicular substances include glass fibers, carbon fibers, PAN-based fibers, metal crystals, metal compound crystals, and the like, as long as they have no affinity (compatibility) with the adhesive main agent. A preferable acicular substance is a crystal of potassium 6-titanate (K ₂ O · 6TiO ₂ ), which is not compatible with water but has an affinity, and has an apparent specific gravity of 0.2 (true specific gravity). = 3.3) and the elastic modulus is 28000 kg / mm ^2, which is suitable as a pressure-sensitive adhesive component.

<Particulate matter>
Microparticulate materials include microsilica, synthetic zeolite, activated alumina gel, calcium carbonate, zinc oxide, titanium oxide, talc, clay, kaolin, activated clay, acrylic beads, starch, cellulose, shirasu balloon, etc. Is suitable in the range of 10 μm to 30 μm, preferably 0.5 μm to 10 μm. Moreover, by adding with an acicular substance, the addition amount of a fine particulate material can be decreased, and the powder fall-off of a fine particulate material can be prevented.

<Additives>
Additives such as polyethylene wax and carnauba wax to improve slipperiness such as handling properties, NIP transport performance and blocking resistance, and UV absorption of ammonia and ethanolamine to prevent deterioration An agent or the like may be added. Further, a nonionic surfactant or an anionic surfactant (mineral oil) may be added as an antifoaming agent, and silica or the like may be added as an antifoaming aid.

<Emulsifying component>
The above-mentioned adhesive main agent, adhesive strength modifier and additive are dispersed in a medium such as water and applied to the substrate in an emulsion state. When emulsifying, an emulsifier is added as necessary. As the emulsifier, oleic acid soap, castor oil potassium soap, casein, glue, gelatin and the like can be used. In addition, in order to prevent secondary aggregation of the adhesive main agent when emulsified, a resin having no affinity with the adhesive main agent can be added. As this resin, water dispersible polymer polyester, thermoplastic elastomer, low molecular polyethylene such as low density polyethylene, ionomer, vinyl acetate-olefin copolymer, and the like can be suitably used.

Such coating amount of pressure sensitive ^{adhesives, 0.1g / m 2 ~10g / m} 2 after drying, preferably 1.0g / m ² ~3.0g / m ² is preferred. Within this range, when printing or printing from above the pressure-sensitive adhesive, the ink can pass through the pressure-sensitive adhesive and reach the substrate, and the transfer of the print layer when peeled can be prevented. . Furthermore, blocking, piling (powder falling), etc. can be prevented, and sufficient adhesion and printability can be obtained.

  The weak pressure-sensitive adhesive layer 4 only needs to be pseudo-adhered. In addition to the above-mentioned pressure-sensitive adhesive, for example, UV curing in which a photopolymerization initiator or the like is added to a solution obtained by dissolving an acrylic resin or an acrylic monomer in an alcohol such as ethyl alcohol. A type of varnish can also be used as a pseudo-adhesive varnish, and is formed by relief printing such as flexographic printing or gravure printing using intaglio.

  Examples of the pressure-sensitive adhesive used for the strong pressure-sensitive adhesive layer 6 include natural rubber latex or a methyl methacrylate graft polymer of natural rubber latex as a main component, and vinyl acetate, acrylic resin, styrene-butadiene copolymer (SBR), and the like. The thing which added at least 1 sort (s) and increased the adhesive force is mentioned. These components are mixed with water and applied by a coating method such as a spray method, a gravure method, a nozzle method, or a flexo method. In addition, silicon dioxide, starch, surfactant, a pigment, ammonium polyacrylate, etc. can also be mixed with an adhesive.

  Next, an example of the method for manufacturing the postcard with lottery 1 according to the present invention will be described with reference to FIG. The postcard with lottery 1 according to the present invention has a postcard body piece 2 and a concealment paper piece 3 attached to a wide paper 7 via a margin 8 and is printed on the front and back in the state of the wide paper 7 on the inner surface. A weak adhesive layer 4 is formed by printing a weak adhesive. Thus, the personal information such as the lottery number 20 and the postal code 21 and the address are printed at predetermined positions on the outer surface of the postcard body piece 2 and the confidential information S is printed on the inner surfaces of the postcard body piece 2 and the concealment paper piece 3 A strong pressure-sensitive adhesive layer 6 is provided by applying a strong pressure-sensitive adhesive at the position, and a weak pressure-sensitive adhesive layer 4 of the postcard main body piece 2 and the concealing paper piece 3 by half-folding at a margin 8 provided substantially at the center of the wide paper 7. The postcard body piece 2 and the concealment paper piece 3 are laminated to conceal the confidential information S, and then the half-folded margin 8 part and both end parts of the wide paper 7 are arranged in the flow direction. The postcard 1 with lottery is manufactured by cutting with a slit line and cutting at a cutting position 9 in a direction perpendicular to the flow direction. The notch 30 and the perforation line 31 are also provided at a predetermined position before the wide paper 7 is half-folded with the margin 8.

  The recipient who has received the postcard 1 with a lottery constructed as described above picks up the concealment sheet piece 3 and the postcard body piece 2 from the notch 30, and the weak adhesive layer 4 formed on the postcard body piece 2. Then, it is peeled off from the interface with the weak adhesive layer 4 formed on the concealment paper piece 3. Then, as shown in FIG. 4, the confidential information S written on the inner surfaces of the postcard main body piece 2 and the concealment paper piece 3 can be read by folding the concealment paper piece 3 at the perforation line 31 to make it spread.

  Furthermore, since it is a New Year's postcard with a New Year's card as a postcard with lottery, the recipient will store it without discarding it at least until the lottery date after looking at the confidential information S written on it. The confidential information S written on the inner surface of the postcard main body piece 2 and the concealing paper piece 3 and the open information O written on the outer surface again come into contact with the recipient. For example, if it is product information, the product It is possible to increase the continuity of the sales promotion effect.

  Next, another example of the method for manufacturing the postcard with lottery 1 according to the present invention will be described with reference to FIG. The postcard with lottery 1 of the present invention is different from the example of the manufacturing method of the postcard with lottery 1 only in the positions where the strong adhesive layer 6, the notch 30 and the perforation line 31 are provided. The same. As shown in FIG. 6, the postcard body piece 2 and the concealment paper piece 3 are attached to the wide paper 7 through the margin 8, printed on the front and back in the state of the wide paper 7, and the weak adhesive on the inner surface. Is printed to form the weak adhesive layer 4. Thus, while printing the personal information such as the lottery number 20 and the postal code 21 at the predetermined position on the outer surface of the postcard body piece 2 and the confidential information S on the inner surfaces of the postcard body piece 2 and the concealment paper piece 3, A strong adhesive is applied to each of the predetermined positions in the vicinity of both ends of the paper 7 to provide strong adhesive layers 6, 6, and a weak adhesive layer is folded in half at a margin 8 provided in the approximate center of the wide paper 7. 4 and the postcard body piece 2 on which the strong pressure-sensitive adhesive layer 6 is formed and the inner surface of the concealment paper piece 3 are overlapped and pressed so that the positions of the weak pressure-sensitive adhesive layer 4 and the strong pressure-sensitive adhesive layer 6 are aligned with each other. After the piece 2 and the concealment paper piece 3 are laminated to conceal the confidential information S, the half-folded margin 8 portion and the both end portions of the wide paper 7 are cut off by the slit line in the flow direction, and the cut position is perpendicular to the flow direction. The postcard with lottery 1 is manufactured by cutting at 9. Note that the notch 30 is blank at a predetermined position on the center side of the concealment paper piece 3, and the perforation line 31 is blank at the predetermined position between the weak adhesive layer 4 and the strong adhesive layer 6 of the concealment paper piece 3. It is provided before half-folding at 8. In addition, although the strong adhesive layer 4 was provided in the predetermined position of the both ends of the wide paper 7, the strong adhesive layer 4 may be either one side. However, when a heat-sensitive adhesive is applied and provided as a strong pressure-sensitive adhesive layer, it is easier to bond the heat-sensitive adhesive layer by applying a heat-sensitive adhesive at predetermined positions near both ends of the wide paper 7. Therefore, it is preferable.

FIG. 7 is a cross-sectional view showing a second embodiment of the postcard with lottery according to the present invention, and FIG. 7 (a) is a cross-sectional view corresponding to the line XX of FIG. FIG. 7B is a cross-sectional view showing a state where the package is opened and spread.
As shown in FIG. 7 (a), the lottery postcard 101 of the second embodiment has a lottery number written on the outer surface of the postcard body piece 2, confidential information written on the inner surface, and the postcard body piece on the inner surface of the postcard body piece. A postcard with a lottery that overlaps the inner surface of a concealment paper piece and is releasably stacked to conceal confidential information described on the inner surface of the postcard body piece, the inner surface of the postcard body piece 2 and the inner surface of the concealment paper piece 3 However, through a pseudo-adhesive sheet 105 in which heat-sensitive adhesive layers 104 and 104 are provided on both sides of a sheet formed by laminating a release resin layer 103 that can be peeled off from the transparent plastic sheet layer 102 on one side of the transparent plastic sheet layer 102. In this configuration, they are superposed, heat bonded and integrated. The transparent plastic sheet layer 102 and the release resin layer 103 can be peeled off.
Then, at one side edge 5 of the long side of the postcard body piece 2 and the concealment paper piece 3, the pseudo adhesive sheet 105 is retracted inward of the postcard 101 with lottery to conceal the inner surface of the postcard body piece 2. A side edge heat-sensitive adhesive layer 106 is formed at a portion directly facing the inner surface of the sheet piece 3, and the postcard body piece 2 and the concealment sheet piece 3 are heat-bonded at the side edge portion 5 so as not to be peeled off. By providing the side edge heat-sensitive adhesive 106, the postcard body piece 2 and the concealment paper piece 3 are not separated during mail sorting or delivery. The direction in which the pseudo adhesive sheet 105 is overlapped between the postcard main body piece 2 and the concealment paper piece 3 is not particularly limited, but the transparent plastic sheet layer 102 of the pseudo adhesive sheet 105 is disposed on the postcard main body piece 2 side and the release resin layer 103. Is laminated so that the cover sheet 3 is on the side of the concealment paper piece 3, and can be easily opened in a spread state when the postcard 101 with a fold is peeled off between the transparent plastic sheet 102 and the release resin layer 103. Therefore, it is preferable.

  The recipient who has received the postcard 101 with a lottery constructed as described above picks up the concealment paper piece 3 and the postcard body piece 2 from the notch 30, and interfaces between the transparent plastic sheet layer 102 and the release resin layer 103. As shown in FIG. 7 (b), the concealment paper piece 3 is folded back at the perforation line 31 so as to be spread, so that the confidential information S written on the inner surface of the postcard body piece 2 is transferred to the transparent plastic sheet layer 102. The confidential information S written on the inner surface of the concealment paper piece 3 can be read through the release resin layer 103 and the heat-sensitive adhesive layer 104.

  Also, the second embodiment has the same effect as the first embodiment, and since it is a postcard with lottery, the recipient should keep it at least until the lottery date after viewing the confidential information S described. Then, on the lottery day, the confidential information S written on the inner surface of the postcard body piece 2 and the concealment paper piece 3 with lottery and the open information O written on the outer surface will again be seen by the recipient, For example, in the case of product information, it is possible to improve the continuity of the sales promotion effect of the product.

  Next, the pseudo-adhesive sheet 105 used for the postcard 101 with lottery according to the second embodiment will be described. Examples of the transparent plastic sheet used for the transparent plastic sheet layer 102 constituting the pseudo-adhesive sheet 105 include polyethylene terephthalate, polypropylene, polyethylene, polystyrene, acetate, polylactic acid, and the like. Polyethylene terephthalate is preferable in view of performance and price such as stability and dimensional stability. In addition, as the transparent plastic sheet, a biaxially stretched film is preferable to an unstretched film because it has more excellent performance such as heat resistance and dimensional stability. The thickness of the transparent plastic sheet is preferably 6 to 50 μm. If the thickness is less than 6 μm, when the release resin layer 103 or the heat-sensitive adhesive layer 104 is laminated, wrinkles occur in the transparent plastic sheet, resulting in a decrease in productivity and quality. When opening a postcard with lottery, it becomes difficult to maintain the spread state.

  The release resin layer 103 constituting the pseudo-adhesive sheet 105 is required to have release properties from the transparent plastic sheet layer 102 and adhesiveness to the heat-sensitive adhesive layer 104 laminated on the release resin layer 103. In particular, the releasability from the transparent plastic sheet layer 102 is such that the recipient of the postcard 101 with lottery can be easily peeled off with a finger and is not peeled off until it is delivered to the recipient. Performance is required. Furthermore, the transparency which the confidential information S can visually recognize is required.

  Examples of the resin of the release resin layer 103 include polyethylene, polypropylene, ethylene ethyl acrylate copolymer, ethylene methyl methacrylate copolymer, ethylene ethyl methacrylate copolymer, ethylene acrylic acid copolymer, and ethylene methacrylate copolymer. A single substance of a known resin such as a polymer, an ethylene vinyl acetate copolymer, an ionomer, or a styrene acrylic resin, or a mixture of two or more of these resins can be used. The formation thickness of the release resin layer 103 is usually about 0.5 to 20 μm. When the formation thickness is less than 0.5 μm, the peel strength between the transparent plastic sheet layer 102 and the release resin layer 103 becomes unstable. Moreover, when the formation thickness exceeds 20 μm, the price increases. Further, the resin of the release resin layer 103 needs to be transparent so that the confidential information S can be visually recognized.

The heat-sensitive adhesive layers 104 and 104 have adhesiveness to the transparent plastic sheet layer 102 and the release resin layer 103, the inner surface of the postcard body piece 2 on which confidential information S is described, the inner surface of the concealment paper piece 3, In addition, heat-sensitive adhesiveness for integrating the described portions of the confidential information S by heat bonding is required. That is, the adhesive force between the heat-sensitive adhesive layer 104 and the transparent plastic sheet layer 102 is f42, the adhesive force between the heat-sensitive adhesive layer 104 and the release resin layer 103 is f43, and the inner surface of the postcard body piece 2 and the heat-sensitive adhesive layer 104. K42, the heat-sensitive adhesive force between the inner surface of the concealing paper piece 3 and the heat-sensitive adhesive layer 104, k43, the heat-sensitive adhesive force between the portion of the confidential information S and the heat-sensitive adhesive layer 104, k4s, transparent plastic When the adhesive force between the sheet layer 102 and the release resin layer 103 is represented by f23, a heat-sensitive adhesive that satisfies the following mathematical formula can be used.
f23 <k42, k43, k4s ≦, f42, f43,
Moreover, the transparency which the confidential information S can visually recognize is required.

  The heat-sensitive adhesive used for the heat-sensitive adhesive layer 104 having these characteristics includes heat-sensitive adhesion in a low temperature region (for example, 100 ° C. or lower) for heat-bonding a postcard body piece, a pseudo-adhesive sheet, and a concealment paper piece. Can be integrated, ethylene vinyl acetate copolymer, vinyl chloride vinyl acetate copolymer, polyvinyl acetate resin, polyester resin, polyethylene resin, polyacrylic resin, chlorinated polypropylene resin, polystyrene resin, A simple substance of a resin appropriately selected from urethane-based resins, polyamide-based resins, or the like, or a mixture obtained by mixing two or more of them can be used.

  The pseudo adhesive sheet 105 is obtained by laminating a release resin layer and a heat-sensitive adhesive layer using a transparent plastic sheet as a base material. As a laminating method, a resin may be laminated on a transparent plastic sheet by an extrusion method, or a resin may be laminated by an emulsion type, a solution type, or hot melt by a coating method. As a specific example of such a pseudo-adhesive sheet, biaxially stretched polyethylene terephthalate (PET) having a thickness of 16 μm is formed on a transparent plastic sheet, polyethylene (PE) having a thickness of 10 μm is formed on a release resin layer, and a heat-sensitive adhesive layer is formed. A configuration in which an ethylene vinyl acetate copolymer (EVA) having a thickness of 8 μm is stacked and <EVA 8 μm / PE 10 μm / PET 16 μm / EVA 8 μm> is given.

  For the postcard 101 with lottery according to the second embodiment of the present invention, the method shown in the other example of the manufacturing method is suitable. The difference from the other examples of the manufacturing method described above is that a side edge heat-sensitive adhesive layer is provided in the strong pressure-sensitive adhesive layer 6 and one of the weak pressure-sensitive adhesive layers is not provided without the weak pressure-sensitive adhesive layers 4 and 4. 4 is that the pseudo-adhesive sheet 105 is overlapped at a position corresponding to 4, and the other points are the same as the other examples of the manufacturing method. That is, the postcard 101 with lottery according to the second embodiment is described with reference to FIG. 6. The postcard body piece 2 and the concealment paper piece 3 are attached to the wide paper 7 through the margin 8, The front and back of the paper 7 are printed, the personal information such as the lottery number 20 and the postal code 21 and the address are given at predetermined positions on the outer surface of the postcard body piece 2, and the confidential information on the inner surfaces of the postcard body piece 2 and the concealment paper piece 3. While printing S, a heat-sensitive adhesive is applied to each of the predetermined positions in the vicinity of both ends of the wide paper 7 to provide heat-sensitive adhesive layers at the positions of the strong pressure-sensitive adhesive layers 6, 6. The pseudo-adhesive sheet 105 is superposed on one of the positions, and then the thermal adhesive layer provided on the inner surfaces of the postcard body piece 2 and the concealment paper piece 3 is positioned mutually in the margin 8 provided in the approximate center of the wide paper 7. Fold in half so that the The postcard body piece 2 and the concealment paper piece 3 are integrated via the cover 105 to conceal the heated confidential information S, and then the half-folded blank portion 8 and both end portions of the wide paper 7 are cut off by slit lines in the flow direction. The postcard with lottery 1 is manufactured by cutting at a cutting position 9 in a direction perpendicular to the flow direction. Others are the same as the other examples of the manufacturing method described above, and a description thereof will be omitted.

As another form of the postcard with lottery according to the present invention, a copy prevention means (not shown) may be provided in the regions 20a and 20b where the lottery number 20 is written on the outer surface of the postcard body piece 2. Examples of the copy preventing means include the following methods.
(1) By two warning marks, a first warning mark having a narrow pitch, for example, 130 lines / inch, and a second warning mark having a wide pitch, for example, 65 lines / inch, on the printed matter. Combining the camouflage pattern (hidden background pattern) that composes the mixed mark and makes these mixed warning marks difficult to see, and by making a printed matter with a printed pattern, it is difficult to distinguish visually. When copying printed matter with a copying machine, a warning mark appears and it is easy to recognize that the printed matter is copied.
(2) A printed material that is a color that is erased or discolored when color copied, and that is printed with a copy check pattern (pictures, characters) using a plurality of halftone dots below a certain scoon density or a plurality of lines below a certain line width. Thus, even if the copy is made, the copy check pattern is not accurately copied due to decoloring, or even if copied, the copy is discolored and is not accurately copied.
(3) By using a pearl ink containing a pearl pigment and printing a pearl print film having a pearl gloss, the pearl print with a pearl gloss is reproduced with an apparent hue and color copy. A method of preventing forgery by color copying that uses different hues.
In addition, the postcard with a lottery year was illustrated as an embodiment of the postcard with lottery of the present invention, but is not limited to this, and is limited by the provisions related to official postcards with lottery numbers. It can be applied to a postcard with lottery, and can be applied to a postcard with lottery with a lottery number such as a New Year postcard with a New Year's card or a summer postcard with a lottery.
