Description

The present invention relates to a portable container and a box-shaped packaged food, for example, a box-shaped portable container made of a cardboard blank plate and a box-shaped packaged food in which the food is stored in the portable container.

Portable containers are required to have transportability and impact resistance. Among the portable containers with such excellent characteristics, plastic molded products, clear cases, paper boxes, and flexible packaging are listed in order as excellent protective containers for carrying around. Paper boxes and clear cases are superior to flexible packaging in terms of protection of fragile contents, but they cannot maintain the shape of plastic molded products, so they are slightly inferior as containers for protecting fragile items. Therefore, if the contents in the paper box or clear case are fragile, replace the contents with a plastic molded product and carry it around, or place it in the bag so that the paper box or clear case will not be crushed. It is necessary to take measures such as devising.

If you try to place a box-shaped container such as a paper box or clear case in a predetermined position in the bag, a fixing member such as a clip is required, but adding a fixing member will increase the cost and portability of the container. It will be damaged. From this point of view, various configurations have been conventionally proposed in order to enable fixing of the box-shaped container without adding a fixing member. For example, in Patent Document 1, a pair of tongue pieces having a vertical relationship in a straight line is formed on the bottom surface of the container at a perforation, and the pair of tongue pieces cut up at the perforation are locked to each other to form an annular shape. , A box-shaped container that can be hooked on a bed or a pipe for a towel rack has been proposed.

Each of the portable cartons 101, 102, 103, and 104 is a box-shaped portable container formed by perforations M1, M2, M3, and M4 so that a pair of arm portions 1 and 2 can be cut and raised. 1 to 4, (A) shows the state before cutting up of the arms 1 and 2, and (B) shows the engaged state of the cut up arms 1 and 2.

A storage space S for storing the contents is provided inside the portable cartons 101 to 104 ((B) in FIGS. 1 to 4). Examples of the contents include foods (for example, confectionery such as chocolate confectionery and candy), cosmetics (for example, make-up cosmetics such as lipstick and nail polish), and the like, but here, an individual containing a plurality of stick confectionery. Packaged food is assumed as the content. Then, the box-shaped packaged food is formed by storing one or a plurality of individually packaged foods in the storage space S. Therefore, applications of the portable cartons 101 to 104 include food cases (confectionery boxes, etc.), cosmetic cases, sales promotion cases, and the like.

The development views of FIGS. 5 to 8 show the blank plates 201, 202, 203, and 204 constituting the portable cartons 101, 102, 103, and 104, respectively. The portable cartons 101-104 are formed by bending one blank plate 201-204. Further, the blank plates 201 to 204 are formed by punching a plate-shaped sheet material as shown in the developed views (FIGS. 5 to 8).

Examples of the sheet material constituting the blank plates 201 to 204 include thick paper (cardboard and the like) and resin plates (transparent or opaque resin plates made of resins such as polyethylene terephthalate and polypropylene). When the mobile cartons 101 to 104 are configured as a resin clear case (transparent plastic case), the contents can be easily visually recognized, and information is displayed (display of product information, etc.) on both the mobile cartons 101 to 104 and the contents. ) Is possible. Regarding the material, the individual wrapping is the same as that of the blank plates 201 to 204, and a material (paper, resin, etc.) can be used as required.

As shown in FIGS. 5 to 8, the blank plates 201 to 204 are formed from the back plate 5; the front plate 6; the side plates 7, 8; the glue margin piece 9; the top plate 10; the over flap plate 11; the bottom plate 12 and the like. It has become. A glue margin piece 5a is provided on the bottom surface side of the back plate 5, and glue margin pieces 6a and 6b are provided on the top surface side of the front plate 6, and the top surface side and the bottom surface side of the side plates 7 and 8 are provided. Flaps 7a, 7b; 8a, 8b are provided on the side, respectively. Glue allowance pieces 5a; Half-cut perforations are formed on the adhesive-coated surfaces of the glue allowance pieces 6a and 6b, and the adhesive strength can be adjusted by the number of perforations.

In the back plate 5, the perforations M1 to M4 for cutting up the pair of arm portions 1 and 2 described above and the notches 1a and 1b for engaging the pair of arm portions 1 and 2 in a state of being assembled in an annular shape, 2a, 2b or notches 1c, 2c are formed. Further, a perforation N2 used for breaking at the time of opening is formed at the boundary of the glue margin piece 6b on the front plate 6.

A linear perforation M5 (for example, pitch: 5 mm cut × 2 mm non-cut) is formed on the front plate 6 (FIG. 8) of the blank plate 204. Then, in the state of being assembled in the portable carton 104 (FIG. 4), by forming a notch in the front plate 6 along the perforation M5, the notch can be used as a card folder. For example, when a perforation M5 having a length of 68 mm is formed at a position 60 mm (11 mm from the left and right ends) from the lower end of the front plate 6, a card of a general size can be inserted into the notch formed by the perforation M5. Is stored in the portable carton 104 in a stable state so as to be placed on the bottom plate 12. Since the upper part of the stored card is exposed from the notch in an appropriate size, it can be easily removed.

Bending lines L1 to L4 made of lead ruled lines and bending lines K1 to K9 made of pressed ruled lines are formed in the blank plates 201 to 203 to form creases. Further, in the blank plate 204, bending lines L3 and L4 made of lead ruled lines and bending lines K1 to K11 made of pressed ruled lines are formed to form creases.

Assembling of the portable cartons 101 to 104 is performed by bending the blank plates 201 to 204 along the bending lines L1 to L4 and K1 to K11 as follows. First, the blank plates 201 to 204 are bent along the bending lines L1, L2 (or K10, K11); K1 and K2, and the glue margin piece 9 is attached to the inside of the side plate 8. The flaps 7b and 8b are bent along the folding lines K5 and K7, the glue margin piece 5a is bent along the folding line K8, and the bottom plate 12 is attached to the glue margin piece 5a.

Since the portable cartons 101 to 104 are in a state of being opened on the top surface side, individually wrapped food is put into the accommodation space S through the opening. Next, the flaps 7a and 8a are bent along the bending lines K4 and K6, the glue margin piece 6a is bent along the folding line L4, the top plate 10 is bent along the bending line L3, and the top plate 10 is bent along the bending line K9. The flap plate 11 is bent, and the top plate 10 and the over flap plate 11 are attached to the glue margin pieces 6a and 6b, respectively. As a result, the storage space S in which the individually packaged food is stored is in a sealed state, and the box-shaped packaged food is stored, transported, and the like in the sealed state.

When the portable cartons 101 to 104 are opened, the overflap plate 11 is caused together with the glue margin piece 6b while cutting the glue margin piece 6b along the perforation N2, and the top plate 10 is caused together with the glue margin piece 6a. As a result, the portable cartons 101 to 104 are opened to the top surface side, and the individually packaged food in the accommodation space S can be taken out from the opening. Since the glue margin piece 6a is attached to the top plate 10 and the glue allowance piece 6b is attached to the over flap plate 11, the over flap plate 11 is inserted inside the front plate 6. Thereby, the portable cartons 101 to 104 can be resealed.

When the portable cartons 101 to 104 are used for carrying around, a pair of arm portions 1 and 2 are cut up along the perforations M1 to M4 formed on the back plate 5, and are assembled in a ring shape at the engaging portions. Engage. The engaging portion is formed so that the pair of arm portions 1 and 2 are engaged in a state of being assembled in an annular shape with a twist. The engaging portions used in the portable cartons 101 to 104 are the notches 1a, 1b, 2a, 2b and the notches 1c, 2c described above. That is, the pair of arms 1 and 2 are engaged with each other so that at least one of the arms 1 and 2 is twisted when the pair of arms 1 and 2 are cut and raised and engaged in an annularly assembled state. Notches 1a, 1b, 2a, 2b or notches 1c, 2c are formed as engaging portions to be fitted.

Among the engaging portions, the notches 1a, 1b, 2a, and 2b have an advantage that a strong engaging state can be obtained, and the notches 1c and 2c have an advantage that they can be easily engaged. It is preferable that the arms 1 and 2 are cut and raised after the contents are taken out from the accommodation space S in order to avoid damage to the contents.

In the portable carton 101 (FIGS. 1 and 5), cuts 1a and 2a are formed in the arm portions 1 and 2 as engaging portions, respectively, and in the portable carton 102 (FIGS. 2 and 6), the arm portion 1 Notches 1c and 2c are formed in 1 and 2 as engaging portions, respectively. In the portable cartons 101 and 102, the support portion 3 has a circular and trapezoidal joint shape so that the pair of arm portions 1 and 2 are cut and raised so that both arm portions 1 and 2 have a common base as the connecting portion 4. Is formed between the arms 1 and 2. On the opposite side of the pair of arm portions 1 and 2 with respect to the support portion 3, the notches 1a and 2a are located in the portable carton 101, and the notches 1c and 2c are located in the portable carton 102. Further, the pair of arm portions 1 and 2 engaged in an annularly assembled state are curved by the twist to form a protruding truncated cone shape (FIGS. 1 (B) and 2 (B)).

In the portable carton 103 (FIGS. 3 and 7), cuts 1a, 1b; 2a, 2b are formed in the arm portions 1 and 2, respectively, as engaging portions. In the portable carton 103, the pair of arm portions 1 and 2 before being cut up are formed side by side so as to form a semicircular opposed circular shape, and both arm portions 1 and 2 connect a common base. A pair of arm portions 1 and 2 are cut up so as to have the portion 4. The circular portion between the arms 1 and 2 is removed after cutting up the pair of arms 1 and 2. In the pair of arm portions 1 and 2, the notches 1a and 2a are located on the outer peripheral side, and the notches 1b and 2b are located on the inner peripheral side. Further, the pair of arm portions 1 and 2 engaged in an annularly assembled state are curved by the twist to form a protruding truncated cone shape (FIG. 3 (B)).

In the portable carton 104 (FIGS. 4 and 8), a notch 1a is formed as an engaging portion in the arm portion 1, and a notch 2a and 2b are formed as an engaging portion in the arm portion 2. In the portable carton 104, a pair of arms 1 and 2 before being cut up are formed side by side so as to extend in the left-right direction, one arm 1 has a base on the left side, and the other arm. A pair of arm portions 1 and 2 are cut up so that the portion 2 has a base on the right side. A notch 1a is located in the arm 1 and a notch 2a, 2b is located in the arm 2 on opposite sides of the pair of arms 1 and 2. Further, the pair of arm portions 1 and 2 engaged in an annularly assembled state are curved by the twist to form a triangular prism shape protruding into a roof shape (FIG. 4 (B)).

The side view of FIG. 9 schematically shows portable cartons 101 and 102 (FIGS. 1 (B) and 2 (B)) in which a pair of arm portions 1 and 2 are assembled and engaged in an annular shape. The pair of arm portions 1 and 2 engaged in an annularly assembled state form a truncated cone shape that protrudes by being curved by the twist, and the tips of the arm portions 1 and 2 are supported by the curvature. It is in contact with 3. The support portion 3 is pressed by the elastic force generated by the curvature of the arms 1 and 2, and the tip thereof moves toward the front plate 6 side (pressing by the arms 1 and 2 toward the front side). This means that the mobile cartons 101 and 102 can be strongly fixed to the object to be fixed by the elastic force of the arms 1 and 2. The pair of arm portions 1 and 2 operate in the same manner in the portable cartons 103 and 104, but in the portable cartons 101 and 102, the support portion 3 is located so as to face the tips of the arm portions 1 and 2. By strongly sandwiching a part of the fixing target between the arm portions 1 and 2 and the supporting portion 3, it is possible to use the device in a stronger fixed state.

FIG. 10 shows an example of using the portable carton 101. FIG. 10 is a front view showing a state in which the portable carton 101 constituting the box-shaped packaged food 301 is fixed to the bag 15. The portable carton 101 is arranged in the bag 15 with the handle 15a located in the ring composed of the arms 1 and 2. The twisted arms 1 and 2 press the bag 15 from the outside with a restoring force (elastic force of the arms 1 and 2) that tries to return to the state before cutting (FIG. 1 (A)), and the twisted arms 1 and 2 press the bag 15 from the outside to the inside of the bag 15. The bag 15 is sandwiched between the support portion 3 and the position. Since the portable carton 101 is firmly fixed to the bag 15, it can be held in that position without being crushed even when the bag 15 is carried around. Therefore, even if the contents contained in the mobile carton 101 are fragile, it can be carried with confidence.

FIG. 11 shows another usage example of the portable carton 101. FIG. 11 is a front view showing a state in which the portable carton 101 constituting the box-shaped packaged food 301 is fixed to the PET bottle 16. The portable carton 101 is fixed to the PET bottle 16 with the bottle upper portion 16a located in the ring composed of the arms 1 and 2. The twisted arms 1 and 2 press the PET bottle 16 from the front side with a restoring force (elastic force of the arms 1 and 2) that tries to return to the state before cutting (FIG. 1 (A)), and the PET bottle 16 The PET bottle 16 is sandwiched between the back plate 5 located on the rear side. Since the portable carton 101 is firmly fixed to the PET bottle 16, it is possible to maintain the position even if the PET bottle 16 is carried around.

As described above, when the pair of arm portions 1 and 2 are engaged in an annularly assembled state at the engaging portions such as the cuts 1a and 2a, a part of the object to be fixed is placed in the ring of the arm portions 1 and 2. The restoring force (elastic force of the arms 1 and 2) at which the twisted arms 1 and 2 are about to return to the pre-cut state ((A) in FIGS. 1 to 4) while being able to be positioned. ) Makes it possible to press the fixed object. Therefore, the mobile cartons 101 to 104 can be used in a state of being strongly fixed to the fixing target without adding a fixing member.

Examples of the objects to be fixed to the portable cartons 101 to 104 include clothes with pockets, in-vehicle cup holders, and the like, in addition to bags and PET bottles. Further, in the portable cartons 101 to 104, a portion having an elongated shape (string shape, rod shape, tubular shape, etc.) in the fixing target is passed through the rings of the arms 1 and 2, so that the fixing target can be easily fixed (hooked, suspended, etc.) It is also possible to hook the arms 1 and 2 on a part of the object to be fixed (pocket or the like) and perform simple fixing only by the elastic force thereof. Therefore, the portable cartons 101 to 104 are excellent not only in portability but also in convenience.

FIG. 12 shows an example of using the portable cartons 101 and 102 in a state where they are not fixed. FIG. 12 is a side view schematically showing an oblique stand state of the portable cartons 101 and 102 constituting the box-shaped packaged foods 301 and 302. Similar to the usage examples shown in FIGS. 10 and 11, the pair of arm portions 1 and 2 engaged in an annularly assembled state are curved by twisting to form a protruding truncated cone shape (FIG. 9). However, this curvature is in the opposite direction. That is, the pair of arm portions 1 and 2 are curved so that their tips are separated from the support portion 3 (inverted curved state).

When the arms 1 and 2 are assembled in the opposite directions as described above and the portable cartons 101 and 102 are placed on the desk T, as shown in FIG. 12, the portable cartons 101 are supported by the arms 1 and 2. , 102 can be made to stand diagonally. In the portable cartons 101 and 102 in the slanted stand state, the food (stick confectionery) Fa can be easily taken out from the individually wrapped food F in the accommodation space S. That is, it is convenient to be able to take out the food Fa without touching the mobile cartons 101 and 102 while working or studying.

In the portable cartons 101 to 104, the positions, shapes, and sizes of the perforations M1 to M4 formed on the back plate 5; the form of the engaging portions (cuts 1a, 2a, etc.); the creases (folding lines L1, L2, etc.). The form and the like are set according to the fixing target, the contents, the manufacturing process (for example, the boxing process for assembling the portable carton) and the like of the portable carton 101 to 104. An example thereof is shown in the developed views of FIGS. 13 to 18. For example, the developed views of FIGS. 13 and 14 show the blank plates 201a and 202a constituting the mobile cartons 101 and 102 as the mobile cartons according to the fifth and sixth embodiments, respectively. .. Further, the developed views of FIGS. 15 to 18 show the blank plates 201b to 201e constituting the mobile carton according to the seventh to tenth embodiments of the modified example of the mobile carton 101. In addition, in the 5th to 10th embodiments, the same effect can be obtained according to the same configuration as in the 1st and 2nd embodiments.

The perforation M1a of the blank plate 201a (FIG. 13) is formed at a higher position on the back plate 5 than the perforation M1 of the blank plate 201 (FIG. 5). The perforation M2a of the blank plate 202a (FIG. 14) is also formed at a higher position on the back plate 5 than the perforation M2 of the blank plate 202 (FIG. 6). Therefore, the portable carton composed of the blank plates 201a and 202a is fixed at a position relatively low with respect to the fixing target, and as a result, a stable fixed state can be obtained.

In the case of the perforation M2a of the blank plate 202a (FIG. 14), the notches 1c and 2c of the arm portions 1 and 2 are deeply formed, so that a more stable engaging state can be obtained and the fixed state with respect to the fixing target can be obtained. Can be further stabilized. Further, contrary to the portable carton composed of the blank plates 201a and 202a, the portable cartons 101 and 102 composed of the blank plates 201 and 202 are fixed at a relatively high position with respect to the fixing target. It is possible to secure a wide display space for display (for example, product information space, advertising / advertising space for sales promotion, cautionary note space, etc.).

The perforations M1b, M1c, M1d, and M1e of the blank plates 201b, 201c, 201d, and 201e (FIGS. 15 to 18) have partially larger blade stoppers than the perforations M1 of the blank plate 201 (FIG. 5). It has become. That is, the blades of the perforations M1b, M1c, M1d, M1e of the blank plates 201b, 201c, 201d, 201e are compared with the size δ0 of the blade stopper (excluding the circular portion in the support portion 3) of the perforation M1 of the blank plate 201. The size δ1 of the stopper (excluding the circular portion in the support portion 3) is longer (for example, δ0 = 1.2 mm, δ1 = 1.5 mm). By partially adjusting the size of the perforated blade stopper in this way, it is possible to effectively prevent the perforation from being torn in the boxing process.

In the bending lines L1a and L2a (FIGS. 15 to 18) of the blank plates 201b, 201c, 201d and 201e, the pitch of the lead ruled lines is larger than that of the bending lines L1 and L2 of the blank plate 201 (FIG. 5). .. For example, the pitch of the lead ruled lines of the bending lines L1 and L2 is 7 mm cut × 7 mm non-cut, whereas the pitch of the lead ruled lines of the bending lines L1a and L2a is 10 mm cut × 20 mm non-cut. By adjusting the pitch of the lead ruled line in this way, it is possible to effectively improve the boxability of the portable carton. The left and right sides of the back plate 5 may be lead ruled lines like the blank plates 201b, 201d, and 201e, or one may be a lead ruled line and the other may be a pressed ruled line like the blank plate 201c.

In the perforations M1c and M1d (FIGS. 16 and 17) of the blank plates 201c and 201d, the distances to the left and right crease positions are longer than those of the perforations M1 (FIG. 5) of the blank plates 201. That is, compared to each distance α0 from the perforation M1 to the bending lines L1 and L2 on the blank plate 201, each distance α1 from the perforation M1c to the bending lines K10 and L2a on the blank plate 201c and the perforation on the blank plate 201d. Each distance α1 from M1d to the bending lines L1a and L2a is long (for example, α0 = 12 mm, α1 = 15 mm). By locating the perforations M1c and M1d farther from the bending lines L1a, L2a and K10 for forming the crease, it is possible to improve the boxability of the portable carton.

Since the size of the back plate 5 is the same for the blank plates 201c and 201d (FIGS. 16 and 17) and the blank plate 201 (FIG. 5), the shift amount of the perforation position: α1-α0 only, the arm portion 1, The width of the connecting portion 4 of 2 is narrowed. That is, the width β1 of the connecting portion 4 of the arm portions 1 and 2 of the blank plate 201c and the arm portions 1 and 2 of the blank plate 201d are compared with the width β0 of the connecting portion 4 of the arm portions 1 and 2 of the blank plate 201. The width β1 of the connecting portion 4 is shortened. Therefore, the widths of the arms 1 and 2, the distance between the arms 1 and 2 (for example, the size of the joint portion between the circle and the trapezoid in the support portion 3), the lengths of the cuts 1a and 2a, etc. The size associated with is shortened. As described above, the adjustment of the size related to the arms 1 and 2 is effective in improving the boxability of the portable carton.

In the blank plate 201e (FIG. 18), both sides of the arm portions 1 and 2 have a curved shape. That is, the portion of the perforation M1e facing the bending lines L1a and L2a has a curved shape that is convex toward the bending lines L1a and L2a. When the shapes of the arms 1 and 2 are curved in this way, it is easy to open the box, and for example, it is possible to effectively prevent the perforation M1e from being torn in the boxing process.

According to the portable cartons 101 to 104 and the like, as described above, when the pair of arm portions 1 and 2 are cut and raised and engaged with the state of being assembled in an annular shape, at least one arm portion 1 and 2 is twisted. Therefore, the mobile cartons 101 to 104 and the like can be strongly fixed to the fixing target (bag 15 and the like) by the elastic force (restoring force) of the twisted arms 1 and 2. Therefore, it is possible to carry the portable cartons 101 to 104 and the like in a firmly fixed state without adding a fixing member. Further, if a plurality of engaging portions such as notches 1a, 1b; 2a, 2b are formed on at least one arm portion 1, 2 as in the portable cartons 103, 104, the inside of the ring composed of the arm portions 1 and 2 is formed. It is possible to adjust the size of the to be fixed.
