Description

[Technical field]

[0001] The present invention relates to a structure of a pillow packaging bag for foods such as steamed meat buns, bean-jam buns, curry buns, dorayaki, daifuku mochi, frozen desserts, etc., particularly for individually packaged foods. [Background technology]

[0002] A typical example of soft packaging for food, etc. is a pillow packaging bag, which is made by sealing food in a plastic film laminated into a cylindrical shape, cutting it to a specified length, and sealing both ends with pressure. This type of pillow packaging bag is back-sealed using a so-called seam-sealing method in which the cylindrical side ends on the back side are joined together, but when trying to open the bag by tearing it widthwise, problems have been pointed out that the tearing is hindered by the seam-sealed part, or the bag tears diagonally from the seam-sealed part, and various structures have been proposed to solve these problems (for example, Patent Document 1).

[0003] However, foods such as the above-mentioned meat buns, bean-jam buns, curry buns, cream buns, dorayaki, daifuku mochi, and frozen desserts are sometimes individually wrapped and sold, and such individually wrapped foods are usually eaten in their original packaging, that is, in the bag without being transferred to other dishes, depending on the occasion, such as lunch or as a light meal or snack on the go. Therefore, this type of packaging bag is also required to have a convenient packaging structure that is easy to open and easy to eat in such a situation. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 4338175 Summary of the Invention [Problem to be solved by the invention]

[0005] To provide a pillow packaging bag structure for individually packaged foods in consideration of the above points, which allows the packaging bag to be easily cut and opened to remove the individual foods contained therein, is hygienic, and allows the food to be held and eaten safely and with peace of mind. [Means for solving the problem]

[0006] In order to solve the above problems, the invention of claim 1 relates to a pillow packaging bag for individually packaged foods, which packages individually packaged foods in a bag shape via a seam seal at the back portion and end seals at both ends, and which is characterized in that a tab portion consisting of an easy-to-open portion is provided in the longitudinal center of the seam seal portion, the seam seal portion is cut widthwise from the tab portion to form a cutting portion that divides the back portion of the packaging bag into a back holding side and a back cut-apart side in a continuous straight line, and a fold portion is formed continuous with the cutting portion to fold the surface portion of the packaging bag into a surface holding side and a surface fold-apart side, and the surface portion is turned over and folded over via the fold portion to form a food holding portion for the individually packaged food.

[0007] The invention of claim 2 relates to a pillow packaging bag for individually packaged food, in which the tab portion in accordance with claim 1 includes a film having fine cut portions and excellent initial openability.

[0008] The invention of claim 3 relates to a pillow packaging bag for individually packaged food as described in claim 1, wherein the cut-away portion includes a special stretched film or a film having micropores and straight-line opening properties.

[0009] The invention of claim 4 relates to the pillow packaging bag for individually packaged food according to claim 1, wherein the individually packaged food is a food to be heated in a microwave oven.

[0010] The invention of claim 5 relates to the pillow package bag for individually packaged food according to claim 1, wherein the individually packaged food is a frozen dessert food. Effect of the Invention

[0011] According to the invention of claim 1, there is provided a pillow packaging bag in which individually packaged foods are packaged in a bag shape via a seam seal portion at the back portion and end seal portions at both ends, a tab portion consisting of an easy-to-open portion is provided in the longitudinal center of the seam seal portion, the seam seal portion is cut in the width direction from the tab portion to form a cutting portion that divides the back portion of the packaging bag into a holding side and a cutting side in a continuous linear manner, a fold portion is formed in the surface portion of the packaging bag continuing from the cutting portion to divide it into a holding side and a fold side, and the surface portion is turned up and folded over via the fold portion to form a food holding portion for the individually packaged food. Therefore, when the tab portion of the seam seal portion is twisted to break and cut in the width direction, the back portion of the packaging bag is cut in a linear manner from the seam seal portion, and by folding the surface portion of the packaging bag continuing from the cutting portion, the individually packaged food can be smoothly exposed and removed, and the food can be held and eaten in a hygienic, safe and secure manner without spilling or dropping.

[0012] According to the invention of claim 2, since the grip portion in claim 1 includes a film having micropores and excellent initial openability, the easy-open portion can be produced simply, efficiently and effectively.

[0013] Furthermore, according to the invention of claim 3, since the cut-away portion in claim 1 includes a special stretched film or a film having a microporous portion and straight-line tearability, the cut-away portion can be produced simply, efficiently and effectively.

[0014] Furthermore, according to the present invention, as in claim 4 or 5, even when the individually packaged food is a microwave oven heated food or a frozen dessert food, the food can be removed, held and eaten smoothly, hygienically, safely and securely, without spilling or dropping, anytime and anywhere, and neither hot nor cold, and the food inside can be eaten without any worries.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] The present invention will be described below with reference to examples. As shown in Figures 1 and 2, the present invention relates to a pillow packaging bag 10 for packaging individually packaged foods such as meat buns M into a bag shape via a joint seal portion 20 at a back portion 11 and end seal portions 21, 22 at both ends. The pillow packaging bag 10 having such a configuration is made by various pillow forming machines known in the art.

[0017] The pillow packaging bag 10 is composed of various laminated plastic films with multiple layers selected in consideration of appearance or functionality, etc. In particular, in this invention, as described below, a film with excellent initial opening properties and provided with a band of micropores (including cuts, scars, etc.) as the easy-to-open tab 30 can be used, or a special stretched film or a film with the above-mentioned micropores can be used to obtain straight-line opening properties for the cut-away portion 40. These laminated films are appropriately selected and used as specific layers, such as inner layers, outer layers, or intermediate layers, in the multi-layer structure depending on the required function.

[0018] The individually packaged meat buns M shown in Fig. 1 are individually frozen and heated in a microwave oven as needed before being eaten. Such products are also called microwave-ready products, and container structures are also known that automatically release steam from within the bag without opening it even if the product is heated in its frozen packaging (e.g., Patent No. 4791876). This invention is particularly useful and advantageous for such individually packaged frozen foods that are heated in a microwave oven and then eaten as is.

[0019] In Fig. 1, a gripping portion 30 consisting of an easy-to-open portion is provided in the longitudinal center of the joint seal portion 20 of the back portion 11 of the pillow packaging bag 10. The gripping portion 30 is a portion that is opened by pinching it with the fingers of both hands when opening it, as shown in the explanatory diagram of Fig. 3. For the gripping portion 30 of the embodiment, a film with excellent initial opening properties is used, in which fine holes (cut portions, scar portions, etc.) are provided in a strip shape in the opening direction (width direction of the joint seal portion 20).

[0020] Then, the hand-seamed seal portion 20 is cut in the width direction from the grip portion 30 to form a cutting portion 40 that cuts the packaging bag back portion 11 in a continuous straight line. As can be clearly understood from the explanatory views of Figures 4 and 5, the cutting portion 40 shown by the dashed line in Figure 1 cuts the packaging bag back portion 11 in Figure 1 into two parts: a back holding side 40A that becomes a food holding portion in the left half of the back portion 11, and a back cut side 40B that is to be removed from the food in the right half of the same.

[0021] The cutting section 40 may use a specially stretched film that has linearity in the cutting direction, or may include a film that has linear opening properties and is provided with band-shaped micropores (cut sections, scar sections, etc.) in the linear direction as described above.

[0022] Next, as shown in front surface portion 12 of pillow packaging bag 10 in Fig. 2, a fold portion 50 is formed in front surface portion 12 of the packaging bag, continuing from cut portion 40. Fold portion 50 is shown by a dashed line in Fig. 2, and folds front surface portion 12 of the packaging bag into two portions, a front surface holding side 50A which serves as a left half portion for holding food, and a front surface folded side 50B which serves as the right half portion away from the food. Fold portion 40 may be configured to have a straightness that does not impede the folding function.

[0023] As can be seen from the explanatory diagrams in Figures 5 and 6, food M is held by the back holding side 40A, which forms the food holding portion of the back portion 11 of the packaging bag, and the front holding side 50A, which forms the food holding portion of the front portion 12 of the packaging bag, while the cut side 40B of the back portion 11 of the packaging bag and the foldable side 50B of the front portion 12 of the packaging bag form the food holding portion 60 for the individually packaged food by turning over and folding the front portion 12 via the folding portion 50. [Industrial Applicability]

[0024] In this way, the pillow packaging bag 10 according to the present invention is formed by cutting the back portion 11 in a continuous straight line from the tab portion 30 of the joint seal portion 20 of the back portion 11 of the packaging bag by the cutting portion 40, forming a folding portion 50 in the front portion 12 of the packaging bag continuing from the cutting portion 40, and turning over and folding the front portion 12 to form a food holding portion 60 for individually packaged foods, so that no part is discarded in order to expose or hold the food M from the packaging bag 10, thereby eliminating the associated environmental and resource problems. In addition, the food M contained therein is held in a double layer by the back portion and front portion that divide the packaging bag 10, so that not only is it securely held, but it is also prevented from becoming soiled by the adhesion of moisture or powder.

[0025] Above all, when the individually packaged food is a microwave oven heated food or a frozen dessert food, the food can be taken out, held and eaten anytime, anywhere, neither hot nor cold, smoothly, hygienically, safely and securely without spilling or dropping. [Explanation of symbols]
