In main part C, as described later, under the state (selling state) before Kaifeng, the main part of packing container antetheca 20 60 with can be interconnected by notch 61, in a plate shape.Further, when breaking a seal, can cut off from packing container antetheca 20 and form taking-up window G by notch 61.

Main part C have by packing container antetheca 20 (before being formed and taking out window G, by main part 60 with can the rectangular plate of notch 61 integration), the receiving space H that surrounds of packing container rear wall 32, packing container left side wall 22 and packing container right side wall 23 and to go up at the fore-and-aft direction opposed direction of packing container rear wall 32 (the packing container antetheca 20 with) be flat box like.In front of paper in Fig. 7, side is the front side of main part C, and the paper inboard in Fig. 7 is the rear side of main part C.On main part C, between packing container antetheca 20 and packing container rear wall 32, cup rear wall 27 is configured with in the mode extended abreast with packing container antetheca 20 and packing container rear wall 32, thus, receiving space H is roughly divided into the front space I of packing container antetheca 20 side (front side) and these two parts of rear space J of packing container rear wall 32 side (rear side) in front and back.Cup rear wall 27 carries out to receiving space H (main part C, in other words, the inside of packing container A) partition wall separated.Front space I and rear space J is the space of the flat box like in front and back in the same size.Front space I and rear space J is interconnected in the position of side more top than cup rear wall 27.Further, the hooking sheet 30 of cup rear wall 27 turns back to rear space J side.

The upper end of receiving space H is opened wide from the conveying end K of the rectangular shape of growing crosswise laterally marked off upward as by each upper edge of packing container left side wall 22 and packing container right side wall 23.When packing container antetheca 20 is formed taking-up window G, conveying end K and this taking-up window G is (with reference to Fig. 2) continuously.

In the front space I of the roughly first half of receiving space H, its lower end is inaccessible by cup diapire 24, its upper end as conveying end K roughly first half and open wide upward.In addition, when being formed with taking-up window G, the top of front space I is forwards opened wide (with reference to Fig. 2) from this taking-up window G.

At this, in receiving space H, the complex marking off each roughly first half of the packing container antetheca 20 of front space I, cup rear wall 27 and cup diapire 24 and packing container left side wall 22 and packing container right side wall 23 forms cup L.It should be noted that, cup L can also comprise each roughly latter half and the packing container rear wall 32 of packing container left side wall 22 and packing container right side wall 23, and in this case, main part C entirety becomes cup L.

In the rear space J of the roughly latter half of receiving space H, its lower end as each lower ora terminalis by cup rear wall 27 and packing container rear wall 32 in the past insert port M (with reference to Fig. 8 (e) described later) from rear to the rectangular shape of growing crosswise marked off and open wide downwards, its upper end as conveying end K roughly latter half and open wide upward.That is, rear space J is the space opened wide up and down between cup rear wall 27 and packing container rear wall 32.

It should be noted that, six views of main part C shown in Figure 8.

Fig. 9 is the exploded perspective view for illustration of the state making rear room B and main part C combine.Figure 10 (a) is the block diagram of packing container A, and represent the state opening lid 4 before sealing, Figure 10 (b) is the right side cross-sectional view of the packing container A of Figure 10 (a).

With reference to Fig. 9, by being combined by the rear room B formed like that above and main part C, thus complete packing container A.Such as food unit 42 to be arranged with front and back 2 in packing container A and the mode often arranging each 6 is accommodated.

Food unit 42 utilizes wrapper to be wrapped into and the unit of individual packaging by the chewing gum of the tabular small pieces as food.Such as, multiple food unit 42 with horizontal arranged and state that is that erect is housed in the receiving space E of rear room B, and is adhered to the rear room rear wall 1 of the rear room B of deployed condition by lining cement (also can for adhesive tape).Equally, multiple food unit 42 is with horizontal arranged and state that is that erect is housed in the front space I of the cup L of main part C, and bonding with the cup rear wall 27 of the cup L of deployed condition.Certainly, can be not bonding with packing container A and accommodate by food unit 42 yet.

First, as shown in Figure 9, the lid 4 of rear room B is formed as the state opened.Now, lid 4 becomes from the upper limb (top 1U) of rear room rear wall 1 state extended upward, roughly becomes same plane with rear room rear wall 1.

It should be noted that, in packing container A, lid 4 is extended from the upper limb of rear room rear wall 1, but the rear wall of this rear room rear wall 1 also along the packing container rear wall 32 of main part C as packing container A plays function.Therefore, lid 4 also can be referred to as from the upper limb of the rear wall of packing container A extended.

Then, make the taking-up window D of rear room B and main part C can notch 61 towards identical direction (being side, front in fig .9), in this condition, rear room B is inserted into the later half portions of the conveying end K of main part C from top, and its inside to main part C is moved.

Thus, rear room B is contained in the rear space J of main part C.Now, among rear room B and main part C, in the horizontal maximum (for wide cut), therefore restraint portion 17 abuts (engaging) relative to each upper edge being in the sidewall of homonymy in left and right in the packing container left side wall 22 of main part C and packing container right side wall 23 from top in the restraint portion 17 of the left and right of the first cap 10 of lid 4.Thus, the situation of room B movement downwards in rear space J after restriction, thus situation about coming off from the insert port M of the bottom side of main part C can be prevented.

With reference to Figure 10, after just having been inserted in the rear space J of main part C by rear room B like this, lid 4 has been opened, and becomes the state extended upward from the upper limb (top 1U) of rear room rear wall 1.Therefore, the top 1U of later room rear wall 1 is folding line, by lid 4 with the mode forwards bending orthogonal relative to rear room rear wall 1, and, in the cover 4, with the first folding guides 12 for folding line, by the second cap 11 with the mode downwards bending orthogonal relative to the first cap 10.Thus, cover 4 and become the state of closing as shown in Figure 1.

With reference to Fig. 1, in a closed condition, lid 4 forms lid.In the cover 4, the first cap 10 covers the top of packing container A, and the second cap 11 covers the front upper (upper portion of packing container antetheca 20) of packing container A.Therefore, the conveying end K being in the main part C on the top of packing container A is inaccessible by the first cap 10.In other words, the first cap 10 forms the upper wall of packing container A.In this case, can in order to the top of packing container A and front upper be covered and arrange lid at cup L and rear these both sides of room B, therefore, it is possible to realize the minimizing of components number.

What the lid 4 of such closedown was adhered to the packing container antetheca 20 of main part C by the lining cement 63 as bonding agency can notch 61.In this condition, packing container A is sealed.

Specifically, lining cement 63 is by being folded in lid 4 and can forming by the double-sided adhesive sheet between notch 61.This double-sided adhesive sheet is formed by the two sides adhesive-applying at thin resin sheet.

In sealed states, main part 60 with can be connected with each other by notch 61, can notch 61 with to cover 4 mutually bonding.

In order to packing container A is broken a seal, if hold lid 4 front-end edge 11A and by lid 4 pull-up.

With reference to Fig. 2, when lid 4 is lifted, accompany with it, can pull and produce fracture along line of perforation 62 by notch 61 tegmentum 4, can be cut off by from packing container antetheca 20 by notch 61.Thus, take out window G and surrounded by the main part 60 of packing container antetheca 20, formed with the size that the taking-up window D (with reference to Fig. 4) with rear room antetheca 16 is roughly the same.After cutting off can notch 61 still bonding and remain in the back side of lid 4.

With reference to Fig. 1 (a) and Fig. 2 (a), as previously mentioned, be provided as the line of perforation 62 arranging and cut off processing line, enabling to be separated from packing container antetheca 20 when breaking a seal with the top covering 4 bonding packing container antethecas 20, can realize possessing the packaging paper container A that alter relevant to the sealing of lid 4 prevents function thus.

Thus, if opened by lid 4 when breaking a seal, being then in can being taken out window G by cutting off and expose by notch 61 of the top of the packing container antetheca 20 of main part C, even if closing cap 4 therefore, also easily distinguishing for breaking a seal.That is, when the lid 4 of closedown being opened behind Kaifeng, can not can cut off packing container antetheca 20 by notch 61, easily distinguish that lid 4 breaks a seal.

In addition, if open lid 4 when breaking a seal, then the top of packing container antetheca 20 is separated from packing container antetheca 20 and opens together with lid 4, takes out window G and exposes on the top of packing container antetheca 20.Taking out window G owing to exposing when opening lid 4, therefore easily to take out being housed in inner food unit 42.Further, preventing function by making packing container A main body have to alter, not needing thus to be packed overall for packing container from outside by the hyaline membrane of polypropylene etc. as in the past, thus the raising of capacity rating, the minimizing of manufacturing cost can be realized.

As cutting off processing line, preferably there is the line of perforation 62 of the short switch-in part being formed at packing container antetheca 20 intermittently.That is, line of perforation 62 handling ease and cut off also easy.

As by lid 4 and can the mutually bonding bonding agency of notch 61, preferably utilize double-sided adhesive sheet.Thus, lining cement easily processes, and can easily by packing container antetheca 20 can notch 61 4 mutually bonding with lid.

Figure 11 (a) is the block diagram of packing container A, represents and opens lid 4 after sealing and by the state of rear room B relative to main part C pull-up, Figure 11 (b) is the right side cross-sectional view of the packing container A of Figure 11 (a).Figure 12 is the block diagram of the state of being closed by lid 4 in the packing container A behind Kaifeng.The block diagram of the state of in rear room B, lid 4 being closed under the state that Figure 13 is room B after taking out from packing container A.It should be noted that, in the block diagram of Fig. 1, Fig. 2, Fig. 9 ~ Figure 13, in front of paper, side is the front side of packing container A, and paper inboard is the rear side of packing container A.

With reference to Fig. 2 and Figure 11, under the state opening lid 4, rear room B can be made to slide between the upper/lower positions shown in the upper position shown in Figure 11 (b) and Fig. 2 (b) relative to main part C.

As shown in Fig. 2 (b), the upper limb being in the front extended plate 8 in the rear room antetheca 16 of the B side, rear room of upper/lower positions separates the interval of regulation from below relative to the hooking sheet 30 (vicinity of the hooking sheet 30 strictly speaking, turned back and the connecting bridge of cup rear wall 27) of the cup rear wall 27 of main part C side and opposed.

As shown in Figure 11 (b), the upper limb being in the front extended plate 8 of the B side, rear room of position relative to cup L side hooking sheet 30 (strictly speaking, the hooking sheet 30 turned back and the connecting bridge of cup rear wall 27) engage from downside, till thus, B slip upward in room is restricted to specified amount Z.

By being formed as the upper position shown in Figure 11, thus, room B and cup L is configured to differing heights, and the upper end of rear room B is more outstanding than cup L, thus easily can take out food unit 42 from rear room B.

In order to be formed as upper position, only catch rear room B (such as, cover 4) and by its pull-up upward.Or the rear room diapire 5 that also the insert port M from main part C can be exposed boosts.

As shown above, rear room B combines with the mode of the mobile specified amount Z that can slide upward relative to cup L and cup L.Therefore, even if do not arrange raising part at the rear side of packing container A in advance and the chewing gum of rank rear (rear room B) be configured in the position higher than the chewing gum of prostatitis (cup L), and only make rear room B slide upward movement relative to cup L when needed, just the chewing gum of rank rear can be configured in the position (with reference to Figure 11) higher than the chewing gum in prostatitis.Thus, described raising part can not be set, therefore, it is possible to realize the miniaturization of packing container A.

That is, in this packing container A, can realize forward lapping multiple row and the easy extractable of each food of accommodating and the miniaturization of container simultaneously.

In order to close packing container A, rear room B is set to upper/lower positions, rear room B (part beyond lid 4) is housed in the rear space J of main part C completely, and cover taking-up window G (with reference to Figure 12) by the second cap 11 of lid 4.Now, the restraint portion 17 of the left and right of the first cap 10 of lid 4 abuts from top relative to each sidewall being in homonymy in left and right in the packing container left side wall 22 of main part C and packing container right side wall 23, therefore, it is possible to prevent from being housed in the situation that the rear room B in rear space J comes off from the insert port M of the bottom side of main part C.

In addition, the taking-up window G being in the upper portion of packing container antetheca 20 is inaccessible by the second cap 11.Further, the otch 21 of the central portion of the front-end edge 11A of the second cap 11 to packing container antetheca 20 is inserted, cover 4 thus and engage with packing container antetheca 20, in order to avoid lid 4 comes off.Thus, the state that lid 4 is closed is maintained.

As shown in figure 13, also only rear room B can be taken out from main part C.Rear room B, by removing the combination with main part C (cup L), forms the packing container that can independently use.Therefore, when being housed in that the food in cup L (chewing gum) has eaten and cup L becomes wasted space, by rear room B is pulled down from cup L, thus under state after remaining chewing gum is housed in the B of room, can carry compactly with the thinness of the about half of original packing container A.That is, when a part of chewing gum had in multiple chewing gums has been eaten, packing container A miniaturization (slimming) can be made and re-use, thus ease of use is good.

At this, in order to remove the combination of rear room B and main part C, consider to have such as overcome restraint portion 17, locking that hooking sheet 30 is formed and method that rear room B is extracted from main part C or a method part of main part C being ruptured and rear room B is taken out.In addition, for this reason, also the line of perforation etc. that can be pre-formed for making main part C rupture cuts off processing line.

In addition, remove with the combination of main part C after the rear room B of single product state lid 4 can be used to close.That is, creasing of the first folding guides 12 place of lid 4 is removed.That is, creasing between second 15 as front portion of the first cap 10 (part as the upper wall of packing container A) and the second cap 11 of the lid as packing container A is removed.Thus, the first cap 10 and the second cap 11 become same plane.

Then, with the second folding guides 13 for folding line (along the second folding guides 13), by second 15 and the second cap 11 with the mode orthogonal relative to first 14 downside bending forward.Thus, cover 4 and become the state of closing as shown in Figure 13.In this condition, in the cover 4, the first 14 as rear portion of the first cap 10 becomes the upper wall of rear room B, and second 15 and the second cap 11 play function as the lid covered in the front of rear room B.

Like this, when rear room B and cup L combines, the lid 4 of rear room B becomes the lid (with reference to Figure 12) of packing container A entirety, to be separated and independently situation, the lid 4 of rear room B becomes the lid of rear room B (with reference to Figure 13) at rear room B from cup L.Therefore, need not be arranged respectively to for the lid of packing container A entirety part and become the part of lid of rear room B, thus can realize the minimizing of components number.

In addition, in the rear room B of free state, under state after being closed by lid 4, the first 14 of the first cap 10 in lid 4 covers the top of rear room B, and second 15 and the second cap 11 cover the front upper (upper portion of rear room antetheca 16) of rear room B.Therefore, the conveying end F being in the top of rear room B is inaccessible by first 14, and the taking-up window D being in the upper portion of rear room antetheca 16 by second 15 and the second cap 11 inaccessible.Therefore, after independent use during the B of room, owing to covering front and the top of room B after 4 coverings, therefore, it is possible to prevent the food situation that forwards outside is unrestrained be housed in rear room B.

Further, inserted by the otch 9 of the central portion of the front-end edge 11A by the second cap 11 room antetheca 16 backward, lid 4 is engaged with rear room antetheca 16, in order to avoid lid 4 comes off, thus maintain the state that lid 4 closes.In addition, when lid 4 being opened when the front-end edge 11A of the second cap 11 is pulled down from the otch 9 of rear room antetheca 16, food unit 42 can be extracted out upward from conveying end F.

Like this, main part C is separated into cup L and rear room B, is formed at the packing container antetheca 20 of cup L and takes out window G, and rear room B can be moved upward relative to cup L.Thus, easily will be housed in the food proper alignment of the inside of main part C, and easily food unit 42 be taken out from cup L and rear room B.

In addition, rear room B, by removing the combination with cup L, can be formed as independent used packing container.In this case, such as, when cup L becomes empty, cup L can be thrown away and only utilize rear room B.

The present invention is not defined as embodiment described above, can carry out various change in the scope that claims are recorded.

Such as, in the first embodiment, consider there is following such variation.Such as, in packing container A, in cup L and rear room B, accommodate food unit 42 respectively, overall arranging with front and back 2 accommodates food unit 42 (with reference to Fig. 2) thus.Also can be replaced in this and multiple rear room B is set, thus arranging with front and back 3 and accommodate food unit 42 above.In this case, by being step-like to extract out multiple rear room B upward, can easily the food unit 42 of each rear room B be extracted out thus.In addition, the number of the food unit 42 of accommodating respectively in cup L and rear room B also can suitably change.

In addition, as the method for closing cap 4, not only can use the method inserted to otch 9,21 by the front-end edge 11A of the second cap 11, the otch of the central authorities of the second cap 11 or formation mountain, the position type of close front-end edge 11A can also be used in and make the method that this otch engages with otch 9,21.In addition, the shape of otch 9,21 is not limited to the roughly U-shaped shown in Fig. 4 or Fig. 7, also can for turn upside down roughly U-shaped, substantially V-like shape, roughly M word shape, the rectilinear form etc. that extends transversely.

In addition, as the combined method (method for making of packing container A) of rear room B and main part C (cup L), also can in main part C, under that extended for left side plate 25 is not bonding with the extended plate in the right side 26 state, rear room B is contained in rear space J and combines with main part C, afterwards, extended for left side plate 25 is bonding with the extended plate in the right side 26 and complete packing container A (with reference to Fig. 1).

In addition, lid 4 bonding in employ double-sided adhesive sheet, but as bonding agency, to be not limited thereto.Such as, at least one party in opposite bonding plane the lining cement such as hot melt, water-soluble lining cement can be applied.

In addition, as the food being contained in packing container A, be not particularly limited, but the rectangular food of tabular of preferred foregoing individual packaging.As the rectangular food of such tabular, except chewing gum, it can also be chocolate or candy.

In addition, in packing container A, lid 4 is extended from the upper limb of rear room rear wall 1, but also can be extended from the upper limb of the packing container rear wall 32 of main part C.But, now, in order to easily rear room B be extracted out upward or be pressed into downwards, need to arrange pinch hand separately in advance.In addition, although not shown, the packing container (specifically, the rear room B of independent state) that can utilize separately also can be made to possess aforesaid altering and to prevent function.

In addition, the variation of the first above-mentioned embodiment also can be applicable to the second ~ four embodiment of following explanation.

With reference to Figure 18 and Figure 19, the major part of packing container antetheca 20 forms the antetheca of cup L, and remaining part being in the packing container antetheca 20 of the below of this antetheca forms the antetheca of waste product room 81.The major part of packing container left side wall 22 forms the left side wall of cup L, and remaining part being in the packing container left side wall 22 of the below of this left side wall forms the left side wall of waste product room 81.The extended plate 86 in lower-left is provided with at this left side wall.The major part of packing container right side wall 23 forms the right side wall of cup L, and remaining part being in the packing container right side wall 23 of the below of this right side wall forms the right side wall of waste product room 81.This right side wall is provided with the extended plate 87 in bottom right.The size of the opening downwards of waste product room 81 towards the inner side bending of main part C3, suppresses less by the extended plate 87 of the extended plate in lower-left 86 and bottom right in the main part C3 of the state of assembling.

The extended plate 25 in a left side of main part C3 is provided with packing container lower wall 88 continuously, inserts sheet 89 for a pair, 90, a pair card lacing film 91,92.Packing container lower wall 88 and a pair insert sheet 89,90 and are configured to make lid 82 can opening and closing.

With reference to Figure 21 and Figure 22, in the main part C3 of the state of assembling, the gap of insertion sheet 89 to left down between extended plate 86 and packing container antetheca 20 (more specifically, being reflex part 85) of a side is inserted.Insertion sheet 90 gap that downward-extension is arranged between plate 87 and packing container antetheca 20 (reflex part 85) to the right of the opposing party is inserted.When opening lid 82, a pair card lacing film 91,92 abuts with the extended plate 87 of the extended plate in lower-left 86 and bottom right, limits the open angle of lid 82 thus.When closing cap 82, a pair not extended with lower-left plate 86 of card lacing film 91,92 and the extended plate 87 in bottom right abut, and do not abut with cup diapire 24.

Under the state opening lid 82, waste product room 81 is by insert for a pair between sheet 89,90 and between the extended plate 87 of the extended plate in lower-left 86 and bottom right and ft connection.

Also structure that can be relevant by the waste product room 81 to packing container A3 is applicable to first and second embodiment and embodiment described later.

Figure 23 is the block diagram of the packing container A4 of the 4th embodiment of the present invention, represents the state opening lid 4 before sealing.Figure 24 is the block diagram of packing container A4, represents the state of closing cap 4 and sealing.Figure 25 is the block diagram of packing container A4, represents the state opening lid 4 after sealing.

Packing container A4 has main part C4 and rear room B.Main part C4 is structure taking-up window G being formed at paper mold (not shown) in aforesaid main part C.The packing container antetheca 20 of main part C4 is formed as U-shaped to same shape with aforesaid main part 60 (with reference to Fig. 2).

That is, the taking-up window G as peristome exposed when opening lid 4 is formed in the upper front surface of the packing container antetheca 20 of main part C4.As shown in figure 23, take out window G to be covered by diaphragm 95 before Kaifeng.

Diaphragm 95 is made up of plastic film.In addition, diaphragm 95 is formed greatly, to guarantee required bonding surplus around the taking-up window G in packing container antetheca 20 than taking out window G.In addition, diaphragm 95 also can be formed as the size identical with the back side covering 4, or is formed greatly than the back side of lid 4, but is preferably formed less than lid 4, in order to avoid stretch out from lid 4.

With reference to Figure 23 and Figure 24, in sealed states, diaphragm 95 is bonding by sandwiched lining cement 96 between which with the upper front surface of packing container antetheca 20.In addition, diaphragm 95 is bonding by sandwiched lining cement 97 between which with the back side of lid 4.Specifically, lining cement 96 and lining cement 97 are consisted of aforesaid double-sided adhesive sheet.It should be noted that, as lining cement 96,97, also can use hot melt or water-soluble lining cement etc.Such as, the bonding force carrying out bonding lining cement 97 to diaphragm 95 and the back side of lid 4 is set be better than bonding force diaphragm 95 and the front surface of packing container antetheca 20 being carried out to bonding lining cement 96.

Thus, when breaking a seal opening lid 4, as shown in figure 25, diaphragm 95 is pulled down from the upper front surface of packing container antetheca 20 (specifically, taking out peripheral part of window G) together with lid 4, taking-up window G is exposed.

In addition, significantly reduce when the bonding force of lining cement 96,97 is set to and peels off after bonding.In order to avoid the diaphragm 95 peeled off during Kaifeng is again bonding with packing container antetheca 20.

Like this, by covering the diaphragm 95 and lining cement 96,97 that take out window G, can realize possessing the packaging paper container A4 altering and prevent function.Such as, when being broken a seal by lid 4, diaphragm 95 peels off from packing container antetheca 20 and takes out window G and expose, even if closing cap 4 therefore, also easily distinguishes for breaking a seal.

In addition, take out that window G and the diaphragm 95 that covers this taking-up window G are preferably provided in that lid 4 is closed and under the state overlapping with packing container antetheca 20, tegmentum 4 blocks and do not observe.In this case, the outward appearance of the packing container A4 of the state of closing cap 4 can be made good.

In addition, diaphragm 95 also can use the metallic paper such as thin paper or aluminium foil.And, can the bonding force of lining cement 96 being designed stronger, when breaking a seal opening lid 4, a part for diaphragm 95 being broken and remainder is still bonding and remain on packing container antetheca 20.

It should be noted that, also can be applicable to aforesaid each embodiment by the structure preventing function relevant of altering of packing container A4.

In addition, various design modification can be implemented in the scope of the item described in claims.
