Description

Technical Field

[0001] The present invention relates to a laminated peelable container, and in particular to a laminated peelable container whose opening is not easily peeled off. Background Art

[0002] With the rapid development of various technologies, the application of laminated peelable containers is becoming more and more extensive. However, in the use of laminated peelable containers, when the inner layer and the outer layer of the main body are in a peeling state, it is easy to cause the inner layer and the outer layer of the opening to peel at the same time, and then the inner layer and the outer layer are completely peeled off, causing inconvenience in use. This problem is also the bottleneck of current manufacturing. The inner layer must be easy to peel off so as not to affect the discharge of the contents, but it is not desirable to peel off completely. The two are conflicting designs.

[0003] Based on the above, there is an urgent need in the market to develop a laminated peelable container that can effectively prevent the inner layer and the outer layer from completely peeling off and does not affect the discharge of the contents. Summary of the invention

[0004] The present invention provides a laminated peeling container. The first tight contact area of ​​the first layer and the second tight contact area of ​​the second layer are both located at the opening of the laminated peeling container and are tightly attached to each other, so that the first layer and the second layer are not easy to be peeled off at the opening and the discharge of the content is not affected.

[0005] According to one embodiment of the present invention, a laminated peeling container is provided, which has a main body and an opening. The opening is closer to the opening of the laminated peeling container than the main body. The main body inner surface of the main body and the opening inner surface of the opening form a storage space of the laminated peeling container. The laminated peeling container includes a first layer and a second layer. The first layer includes a first close-fitting area. The first layer is closer to the main body than the second layer and is exposed on the main body inner surface. The second layer includes a second close-fitting area. The first close-fitting area and the second close-fitting area are close to each other. The first close-fitting area and the second close-fitting area are both located at the opening of the laminated peeling container. The second close-fitting area includes a second opening section. The second opening section is exposed on the opening inner surface and extends from the opening toward the main body. The first close-fitting area includes an interlayer section. The second close-fitting area also includes an inner close-fitting section. At least a part of the interlayer section and the inner close-fitting section are close to each other, and the interlayer section is not exposed on the opening inner surface. The second opening section is connected to the inner close-fitting section. In this way, the first layer and the second layer are not easily peeled off at the opening, and the discharge of the contents is not affected.

[0006] According to the embodiment of the laminated peeling container, the inner clinging section may be closer to the inner surface of the opening than the sandwich section.

[0007] According to the embodiment of the laminated peeling container, the inner clinging section may not be exposed on the inner surface of the opening.

[0008] According to an embodiment of the laminated peeling container, the inner diameter of the inner surface of the opening decreases in a direction from the opening toward the main body.

[0009] By using the laminated peelable container of the embodiment, the first layer is kept exposed on the inner surface of the opening, thereby achieving the effect of preventing peeling and reducing the manufacturing complexity.

[0010] According to another embodiment of the present invention, a laminated peeling container is provided, which has a main body and an opening. The opening is closer to the opening of the laminated peeling container than the main body. The main body inner surface of the main body and the opening inner surface of the opening form a storage space for the laminated peeling container. The laminated peeling container includes a first layer and a second layer. The first layer includes a first tight-fitting area. The first layer is closer to the main body than the second layer and is exposed on the main body inner surface. The second layer includes a second tight-fitting area. The first tight-fitting area and the second tight-fitting area are in close contact with each other. The first tight-fitting area and the second tight-fitting area are both located at the opening of the laminated peeling container and form an inward folding structure. The second tight-fitting area includes a second opening section. The second opening section is exposed on the inner surface of the opening and extends from the opening toward the main body. The first tight-fitting area includes an interlayer section. The second tight-fitting area also includes an inner tight-fitting section. At least a portion of the interlayer section and the inner tight-fitting section are in close contact with each other, and the interlayer section is not exposed on the inner surface of the opening. The second opening section is connected to the inner tight-fitting section. Thereby, the first layer and the second layer are not easily peeled off at the opening, and the manufacturing cost of the laminated peelable container can be reduced and the production efficiency can be improved.

[0011] According to the embodiment of the laminated peeling container, the second close contact area may further include an outer close contact section, the inner side surface of the sandwich section and at least a portion of the inner close contact section are in close contact with each other, and the outer side surface of the sandwich section and at least a portion of the outer close contact section are in close contact with each other.

[0012] With the laminated peeling container of the above embodiment, the interlayer section of the first layer is covered by the second layer to help improve the strength of the close contact. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The following will describe multiple embodiments of the present invention with reference to the accompanying drawings. For the sake of clarity, many practical details will be described together in the following description. However, it should be understood that these practical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these practical details are not necessary. In addition, in order to simplify the illustration, some conventional structures and components will be depicted in a simple schematic manner in the illustration; and repeated components may be represented by the same number.

[0050] Figure 1A A three-dimensional diagram of a peelable laminated container 100 according to a first embodiment of the present invention is shown. Figure 1B A side view of the peelable laminated container 100 according to the first embodiment is shown. Figure 1C Draw according to Figure 1B A cross-sectional view of the laminated peelable container 100 along the section line 1C-1C, Figure 1D Draw according to Figure 1C Schematic diagram of local 1D in . Please refer to Figures 1A to 1DThe laminated peeling container 100 has a main body 150 and an opening 160. The opening 160 is closer to the opening 175 of the laminated peeling container 100 than the main body 150. The main body inner surface 154 of the main body 150 and the opening inner surface 164 of the opening 160 form a accommodating space 170 of the laminated peeling container 100. The laminated peeling container 100 includes a first layer 110 and a second layer 120.

[0051] Please refer to Figure 1D The first layer 110 includes a first close contact area 111. The first layer 110 is closer to the main body 150 than the second layer 120 and is exposed on the inner surface 154 of the main body. The second layer 120 includes a second close contact area 122. The first close contact area 111 and the second close contact area 122 are close to each other. The first close contact area 111 and the second close contact area 122 are both located at the opening 160 of the laminated peeling container 100. In this way, the first layer 110 and the second layer 120 are not easily peeled off at the opening 160, and the discharge of the contents is not affected. Furthermore, the first layer of the laminated peeling container according to the present invention refers to the innermost layer in the main body, and the second layer refers to the outer layer other than the innermost layer in the main body, and the number of the second layer can be more than two layers.

[0052] Specifically, the first and second adhesion areas 111 and 122 are both located at the opening 160 of the laminated peelable container 100 and form an inner folding structure 130. This helps prevent the first and second layers 110 and 120 from peeling off at the opening 160, and reduces the manufacturing cost of the laminated peelable container 100 and improves its production efficiency.

[0053] To further explain, the inward folding structure 130 increases the contact area of ​​the first layer of the blank in a general blow molding process, thereby increasing its friction to achieve the functions of close contact and covering, and can be integrally formed on a blow molding machine without the need for additional equipment.

[0054] Furthermore, the first close contact area 111 and the second close contact area 122 can be formed during the manufacturing process of the laminated peelable container 100. For example, the first close contact area 111 and the second close contact area 122 can be formed during the manufacturing process when the blow needle enters the preform of the laminated peelable container 100 before being formed or melted. When the blow needle enters the opening of the preform, the outer wall of the blow needle fits the first layer of the preform (i.e., the inner layer or the innermost layer of the preform), and at least a portion of the first layer of the preform is pulled down by the outer wall of the blow needle and folded back along the inner surface of the opening, so that the first layer and the second layer of the preform (i.e., the outer layer of the preform) are in close contact, and the inner folding structure 130 is formed by the extrusion and cutting of the outer wall of the blow needle and the mold, so that the contact area between the first layer 110 and the second layer 120 (i.e., the inner layer and the outer layer) of the laminated peelable container 100 after forming is increased, and the second layer 120 forms a function of covering the first layer 110 at the opening 160 so that it is not easy to peel off. The thickness of the first layer 110 at the opening 160 may be inconsistent, because when the blow needle enters the opening of the blank, the thickness of the first layer 110 at the opening 160 is squeezed from the opening 175 toward the main body 150, thereby changing from thin to thick (not shown), and the shape of the inner surface 164 of the opening corresponds to the shape of the outer wall of the blow needle. Since only the shape of the inner surface 164 of the opening 160 is molded, the external shape and appearance design of the laminated peeling container 100 are not affected. Furthermore, the outer wall of the blow needle can be matched with the geometric shape of the mold to squeeze and cut the blank at the opening, and then blow high-pressure air into it to form a laminated peeling container with different opening shapes in one piece.

[0055] The first close-fitting area 111 includes an interlayer section 116, and the second close-fitting area 122 includes an inner close-fitting section 127. The interlayer section 116 and a portion of the inner close-fitting section 127 are close to each other to increase their friction. The inner close-fitting section 127 is closer to the inner surface 164 of the opening than the interlayer section 116, and the interlayer section 116 is not exposed from the inner surface 164 of the opening. In this way, the interlayer section 116 of the first layer 110 is covered by the second layer 120 to help improve the close-fitting strength. According to an embodiment of the present invention, the laminated peeling container has an opening normal direction, which is the normal direction of the virtual plane surrounded by the opening, and a portion of the second layer exists in a direction perpendicular to the normal direction of the interlayer section and toward the inner surface of the opening.

[0056] Furthermore, the inner clinging section 127 is not exposed on the inner surface 164 of the opening. Thus, maintaining the first layer 110 exposed on the inner surface 164 of the opening can simultaneously achieve the effect of being difficult to peel off and reduce the manufacturing complexity.

[0057] The first close-fitting area 111 further includes a first opening section 115, which is close to another part of the inner close-fitting section 127 and exposed on the inner surface 164 of the opening. The first opening section 115 extends from the opening 175 toward the main body 150 and is connected to the interlayer section 116. In this way, during the manufacturing process of the laminated peeling container 100, only a part of the first layer of the blank is pulled down by the outer wall of the blow needle, folded back along the inner surface of the opening and close to the second layer of the blank, so that the first opening section 115 of the first layer 110 of the laminated peeling container 100 after molding is exposed on the inner surface 164 of the opening at the position of the opening 175, and the first layer 110 and the second layer 120 are not easy to be peeled off at the opening 160.

[0058] The laminated peeling container 100 has an opening normal direction N1, which is the normal direction of the virtual plane 176 surrounded by the opening 175. In the opening normal direction N1, the ratio of the length L6 of the interlayer section 116 to the length L5 of the first opening section 115 is between 0.3 and 1 (including 0.3 and 1). In the first embodiment, the length L6 is 2.4 mm, the length L5 is 6.9 mm, and the ratio of the length L6 to the length L5 is 0.35. The lengths L5 and L6 can be adjusted by the depth of the blow needle entering the blank during the manufacturing process of the laminated peeling container 100. This helps to improve the stability of the close fit.

[0059] The inner diameter of the opening inner surface 164 decreases from the opening 175 toward the main body 150. Thus, the first close contact area 111 is non-parallel to the second close contact area 122, which helps reduce the risk of the opening 160 being easily peeled off and takes into account the manufacturing convenience. In addition, the shape of the opening inner surface 164 can correspond to the shape of the outer wall of the blow needle during the manufacturing process of the laminated peeling container 100 (that is, at least a portion of the outer wall of the blow needle is wide at the top and narrow at the bottom). According to other embodiments of the present invention, the shape of the outer wall of the blow needle can also be other geometric shapes.

[0060] The second close-fitting area 122 further includes an outer close-fitting section 128, the inner side surface 117 of the sandwich section 116 and the part of the inner close-fitting section 127 are in close contact with each other, and the outer side surface 118 of the sandwich section 116 and a part of the outer close-fitting section 128 are in close contact with each other to increase the friction force, and the sandwich section 116 is not exposed from the opening inner surface 164. In this way, the sandwich section 116 of the first layer 110 is covered by the second layer 120 to help improve the close-fitting strength.

[0061] Specifically, the first close-fitting area 111 includes the first opening section 115 and the interlayer section 116 in order from the opening 175 toward the main body 150, and the second close-fitting area 122 includes the inner close-fitting section 127 and the outer close-fitting section 128 in order from the inner surface 164 of the opening through the opening 175 toward the outer surface 169 of the opening, that is, the inner close-fitting section 127 and the outer close-fitting section 128 of the second close-fitting area 122 cover the interlayer section 116 of the first close-fitting area 111 and are connected to the direction in which the interlayer section 116 is away from the main body 150. The first close-fitting area 111 and the second close-fitting area 122 form an inward folding structure 130, which can be formed by inward folding only the first layer of the blank of the laminated peeling container 100. Furthermore, the first opening section 115 of the first close-fitting area 111 is exposed on the inner surface 164 of the opening, and the second close-fitting area 122 is not exposed on the inner surface 164 of the opening.

[0062] Figure 2 A partial cross-sectional view of a laminated peelable container 200 according to a second embodiment of the present invention is shown. Figure 2 The laminated peeling container 200 has a main body 250 and an opening 260. The opening 260 is closer to the opening 275 of the laminated peeling container 200 than the main body 250. The main body inner surface 254 of the main body 250 and the opening inner surface 264 of the opening 260 form a containing space 270 of the laminated peeling container 200. The laminated peeling container 200 includes a first layer 210 and a second layer 220. The first layer 210 includes a first close contact area 211. The first layer 210 is closer to the main body 250 than the second layer 220 and is exposed on the main body inner surface 254. The second layer 220 includes a second close contact area 222. The first close contact area 211 and the second close contact area 222 are close to each other. The first close contact area 211 and the second close contact area 222 are both located at the opening 260 of the laminated peeling container 200 and form an inner folding structure 230.

[0063] The first close-fitting area 211 includes an interlayer section 216, and the second close-fitting area 222 includes an inner close-fitting section 227 and an outer close-fitting section 228. The inner side surface 217 of the interlayer section 216 and the inner close-fitting section 227 are in close contact with each other, and the outer side surface 218 of the interlayer section 216 and the outer close-fitting section 228 are in close contact with each other. There may or may not be an air gap (not numbered in the figure) in the interlayer section 216. The inner close-fitting section 227 is closer to the interlayer section 216 and exposed to the inner surface 264 of the opening, and the interlayer section 216 is not exposed to the inner surface 264 of the opening. Furthermore, the inner diameter of the inner surface 264 of the opening decreases from the opening 275 toward the main body 250.

[0064] The second close-fitting area 222 further includes a second opening section 225, which is exposed on the inner surface 264 of the opening and extends from the opening 275 toward the main body 250. In this way, during the manufacturing process of the laminated peeling container 200, a portion of the first layer and a portion of the second layer in the blank are pulled down by the outer wall of the blow needle and folded back along the inner surface of the opening, so that the first layer and the second layer of the blank are closely attached to each other, increasing the contact area and friction force, and making the second layer 220 of the laminated peeling container 200 exposed on the inner surface 264 of the opening at the position of the opening 275, and the first layer 210 and the second layer 220 are not easy to be peeled off at the opening 260.

[0065] Furthermore, the sandwich section 216 and the inner close section 227 are close to each other, and the sandwich section 216 is not exposed from the opening inner surface 264, and the second opening section 225 is connected to the inner close section 227. Thus, the inner folding structure 230 of the blank of the laminated peeling container 200 is realized in which the first layer and the second layer are folded inwardly together.

[0066] Specifically, the second close-fitting area 222 includes an inner close-fitting section 227, a second opening section 225, and an outer close-fitting section 228 in order from the opening inner surface 264 through the opening 275 toward the opening outer surface 269, that is, the inner close-fitting section 227, the second opening section 225, and the outer close-fitting section 228 of the second close-fitting area 222 cover the sandwich section 216 of the first close-fitting area 211 and are connected in the direction of the sandwich section 216 away from the main body 250. The first close-fitting area 211 and the second close-fitting area 222 form an inward folding structure 230, which can be formed by folding the first layer and the second layer of the blank of the laminated peeling container 200 inwardly. Furthermore, the second opening section 225, the inner close-fitting section 227, and the first close-fitting area 211 of the second close-fitting area 222 are exposed in order from the opening 275 toward the main body 250 on the opening inner surface 264.

Figure 3 The laminated peeling container 300 has a main body 350 and an opening 360. The opening 360 is closer to the opening 375 of the laminated peeling container 300 than the main body 350. The main body inner surface 354 of the main body 350 and the opening inner surface 364 of the opening 360 form a containing space 370 of the laminated peeling container 300. The laminated peeling container 300 includes a first layer 310 and a second layer 320. The first layer 310 includes a first close contact area 311. The first layer 310 is closer to the main body 350 than the second layer 320 and is exposed on the main body inner surface 354. The second layer 320 includes a second close contact area 322. The first close contact area 311 and the second close contact area 322 are close to each other. The first close contact area 311 and the second close contact area 322 are both located at the opening 360 of the laminated peeling container 300 and form an inner folding structure 330.

[0068] The first close contact area 311 includes an interlayer section 316, and the second close contact area 322 includes an inner close contact section 327 and an outer close contact section 328.

The inner close contact section 327 is closer to the interlayer section 316 and exposed to the opening inner surface 364, and the interlayer section 316 is not exposed to the opening inner surface 364. In addition, the inner diameter of the opening inner surface 364 decreases from the opening 375 toward the main body 350.

[0069] The second close-fitting area 322 further includes a second opening section 325 . The second opening section 325 is exposed at the opening inner surface 364 and extends from the opening 375 toward the main body 350 . The second opening section 325 is connected to the inner close-fitting section 327 .

[0070] Specifically, the second close-fitting area 322 includes an inner close-fitting section 327, a second opening section 325, and an outer close-fitting section 328 in order from the opening inner surface 364 through the opening 375 toward the opening outer surface 369, that is, the inner close-fitting section 327, the second opening section 325, and the outer close-fitting section 328 of the second close-fitting area 322 cover the sandwich section 316 of the first close-fitting area 311 and are connected in the direction of the sandwich section 316 away from the main body 350. The first close-fitting area 311 and the second close-fitting area 322 form an inward folding structure 330, which can be formed by folding the first layer and the second layer of the blank of the laminated peeling container 300 inward. Furthermore, the second opening section 325, the inner close-fitting section 327, and the first close-fitting area 311 of the second close-fitting area 322 are exposed in order from the opening 375 toward the main body 350 on the opening inner surface 364.

Figure 4 The laminated peeling container 400 has a main body 450 and an opening 460. The opening 460 is closer to the opening 475 of the laminated peeling container 400 than the main body 450. The main body inner surface 454 of the main body 450 and the opening inner surface 464 of the opening 460 form a containing space 470 of the laminated peeling container 400. The laminated peeling container 400 includes a first layer 410 and a second layer 420. The first layer 410 includes a first close contact area 411. The first layer 410 is closer to the main body 450 than the second layer 420 and is exposed on the main body inner surface 454. The second layer 420 includes a second close contact area 422.
