Detailed Implementation

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] Please see Figure 1-7 This utility model discloses a coffee capsule sealing device 100 for sealing coffee capsules 200 having a sealing element 210. The coffee capsule sealing device 100 includes a base 20 and a top cover 10, and the top cover 10 is detachably connected to the base 20.

[0044] The base 20 includes a base 25 and a receiving seat 26 that protrudes upward from the base 25.

[0045] The receiving seat 26 is provided with a receiving groove 22 and a main body portion 21 surrounding the receiving groove 22. The receiving groove 22 has an upward-facing opening, and the main body portion 21 has a sidewall surrounding the opening. The coffee capsule 200 has an outwardly extending edge 220a, specifically the edge 220a of the capsule shell or cup body 220 of the coffee capsule 200. The receiving groove 22 is used to receive the coffee capsule 200, and the upper edge of the sidewall of the main body portion 21 abuts against the edge 220a of the coffee capsule 200.

[0046] The receiving seat 26 also has a first enclosure 23 surrounding the main body portion 21, the upper edge of the first enclosure 23 being lower than the upper edge of the side wall of the main body portion 21 to provide clearance space so that the seal 210 wraps downward around the coffee capsule 200 when it is pressed; and the first enclosure 23 has a notch 24 for exposing the main body portion 21, the function of which is described in detail below.

[0047] The base 25 and the receiving seat 26 (including the receiving groove 22) can be integrally molded from plastic material. The base 25 protrudes outward from the periphery of the receiving seat 26 to form a protrusion 204 for abutting against the end of the upper cover 10 (see...). Figure 7 ).

[0048] The base 25 is hollow to reduce the weight of molding material and product. The receiving groove 22 protrudes toward the base 25, and the first enclosure 23 extends smoothly and continuously from the periphery of the main body portion 21, that is, there is no gap between the first enclosure 23 and the periphery of the main body portion 21.

[0049] Please refer to the following: Figure 2 and Figure 11-12 The notch 24 exposes one-quarter to three-quarters of the main body portion 21. The one-quarter to three-quarters refers to one-quarter to three-quarters of a circumferential portion. Figure 2 The figure shown is one-half; Figure 11 The figure shown is one-quarter; Figure 12 The figure shown is three-quarters. The notch 24 exposing one-quarter to three-quarters of the main body portion 21 also refers to the length of the notch 24 (see [reference]). Figure 11 The distance between the two ends 24a and 24b (as indicated in the diagram) is one-quarter to three-quarters of the main body 21, which also refers to the remaining portion of the first enclosure 23 occupying only one circumferential direction. The notch 24 exposes the main body 21, facilitating the removal of the coffee capsule 200 after the top cover 10 is separated.

[0050] In this embodiment, the two ends of the notch 24 are not regular straight lines, but oblique lines with a certain chamfer. Notches 24 of various shapes should be included within the inventive spirit of this application.

[0051] The height of the notch 24 is designed to accommodate the user's thumb; that is, the height of the notch 24 is approximately equal to the width of a thumb, allowing the user's thumb to slide upwards to remove the coffee capsule 200. See also Figure 2 The height of the notch 24 is the distance between the upper end and the lower end of the notch 24. In this embodiment, the height of the notch 24 is also basically equivalent to the height of the receiving seat 26.

[0052] The width of the upper edge of the sidewall of the main body 21 is smaller than the width of the edge 220a of the coffee capsule 200, so that a portion of the edge 220a of the coffee capsule 200 protrudes from the upper edge of the sidewall of the main body 21 (see [link]). Figure 5 This allows the coffee capsule 200 to be grasped upwards from the edge of the notch 24 to remove it.

[0053] The top cover 10 is used to press the seal 210 together. The upper edge of the first enclosure 23 is lower than the upper edge of the side wall of the main body 21 to provide clearance space, so that the seal 210 wraps downward around the coffee capsule 200 when pressed. The seal 210 may be made of aluminum foil to have a certain degree of flexibility for easy pressing, deformation and attachment.

[0054] Please refer to the following: Figure 2 and Figure 8 The upper cover 10 includes a first pressing portion 12 and a second surrounding wall 13 surrounding the first pressing portion 12. The second surrounding wall 13 protrudes away from the first pressing portion 12 and toward the base 20 to form a hollow space for fitting onto the receiving seat 26.

[0055] The end face of the first pressing part 12 forms a first pressing surface. When the second enclosure 13 is fitted onto the receiving seat 26, the first pressing surface is used to press the portion of the sealing member 210 that is opposite the edge 220a of the capsule shell or cup body 220.

[0056] The first pressing part 12 is a boss that protrudes from the inner surface 11 of the upper cover 10 toward the base 20, and the second wall 13 and the first pressing part 12 have a second pressing part 14, and the second pressing part 14 and the first pressing part 12 have a gap 15.

[0057] The second pressing portion 14 protrudes away from the first pressing portion 12 and toward the base 20. The inner surface of the second pressing portion 14 (i.e., the surface toward the gap 15) forms a second pressing surface for pressing the edge of the seal 210 downward around the coffee capsule 200. See also Figure 3 Before sealing, the edge of the sealing member 210 of the coffee capsule 200 can be relatively wide until it aligns with the outer edge P of the first enclosure 23; during sealing, the inner surface of the second pressing part 14 (i.e., the surface facing the gap 15) forms a second pressing surface, used to press the edge of the sealing member 210 downward around the capsule shell or cup body 220 of the coffee capsule 200 (see...). Figure 8 ).

[0058] Part of the gap 15 forms an air gap (see Figure 8 The function of the air gap is to facilitate the separation of the upper cover 10 from the base 20.

[0059] Please see Figure 9 In another embodiment, the top cover 10 may also be formed by combining a first part 102 and a second part 103, with the second part 103 located at the top of the entire sealing device; the base 20 may also be formed by combining a third part 202 and a fourth part 203, with the fourth part 203 located at the bottom of the entire sealing device.

[0060] The first part 102 and the second part 103 may be fixed and non-removable; the third part 202 and the fourth part 203 may be fixed and non-removable. The interior between the first part 102 and the second part 103 is hollow, and the interior between the third part 202 and the fourth part 203 is also hollow, thus reducing the amount of molding material during molding.

[0061] In use, the capsule shell or cup body 220 of the coffee capsule 200 can be first placed into the base 20, and then coffee powder can be filled into the capsule shell or cup body 220; or the capsule shell or cup body 220 can be pre-filled with coffee powder and then placed into the base 20. The sealing member 210 aligns with the capsule shell or cup body 220 and covers it. Then, the top cover 10 is placed on the base 20 to press and seal it; after sealing, the top cover 10 is separated from the base 20 to remove the coffee capsule 200.

[0062] In summary, the notch 24 can solve the problem in the prior art that the sealed coffee capsule 200 is difficult to remove because the receiving groove 22 is recessed in the base 20.

[0063] Meanwhile, the notch 24 or the first enclosure 23 can also solve the problem of aligning the sealing element 210 with the capsule shell or cup body 220. The alignment of the sealing element 210 and the capsule shell or cup body 220 solves the problem of good sealing and good airtightness. The principle of this solution is explained as follows:

[0064] See Figure 3 The outer edge of the seal 210 can be directly aligned with the outer edge P of the wall thickness of the first enclosure 23 to achieve alignment before sealing, even if the seal 210 is in a specific position before sealing. The wall thickness of this first enclosure 23 is used to align the edge of the seal 210 of the corresponding specification to achieve alignment of the seal 210 before sealing, and it can be calculated and designed to adapt to the seal 210 of the corresponding specification. After alignment, after the top cover 10 is pressed together, and because the upper edge of the first enclosure 23 is lower than the upper edge of the side wall of the main body 21, providing a certain clearance space, the edge of the seal 210 other than the part directly opposite the first pressing part 12 is pressed down by the inner surface of the second pressing part 14 (i.e., the surface facing the gap 15) to wrap around the capsule shell or cup body 220 of the coffee capsule 200.

[0065] See Figure 10 In another embodiment, the edge of the seal 210 may extend outward from the diameter of the circular edge by a pair of extension ears 210a, which can be used to align the two ends of the notch 24 (see [link]). Figure 11 The extended lugs 210a and 24 (marked 24a, 24b) are attached to the capsule shell or cup body 220 containing coffee powder, and then pressed and sealed. The two ends of the extended lugs 210a and 24 (marked 24a, 24b) serve as alignment marks. The extended lugs 210a can also serve as marks for tearing open the coffee capsule 200, meaning the coffee capsule 200 can also be punctured to obtain the coffee powder inside.

[0066] The pair of extension ears 210a can be located on a diameter extension line of the seal 210. At this time, the length of the notch 24 is half. In this embodiment, the capsule shell or cup body 220 is circular in shape, and the length of the notch 24 refers to the arc length, which is half of the circumference of the main body 21.

[0067] It is understood that the notch 24 can also be of other lengths, as long as the position of the extension ear 210a and the two ends of the notch 24 are (see...). Figure 11 Just align the 24a and 24b marked in the diagram. For example... Figure 11 a quarter and Figure 12 At three-quarters of the circumference, the extension ear 210a can be correspondingly positioned at one-quarter and three-quarters of the circumference of the seal 210.

[0068] In other embodiments, the alignment mark of the seal 210 may not be limited to the extension ear 210a, but may be other special marks, such as laser markings.

[0069] Understandable, such as Figure 3 Due to the alignment effect of the first enclosure 23 provided in this application, the sealing member 210 may not necessarily be provided with the aforementioned extended ears or laser markings.

[0070] In other embodiments, the capsule shell or cup 220 may be square in shape, in which case the receiving groove 22 and the main body 21 are also square. In this case, the length of the notch 24 is preferably one-quarter, that is, the two ends of the notch 24 are the two ends of one sidewall along one circumferential direction of the main body 21. Alternatively, the capsule shell or cup 220 may be triangular pyramidal in shape, in which case the receiving groove 22 and the main body 21 are also triangular pyramidal. In this case, the length of the notch 24 can be one-third, that is, the two ends of the notch 24 are the two ends of one side along one circumferential direction of the main body 21.
