Description

Technical Field

[0001] The utility model relates to a blister packaging technology, in particular to a blister packaging piece which can be opened and closed repeatedly. Background Art

[0002] In the existing blister packaging process, the blister package is composed of a preformed blister and a substrate attached to the blister by a non-detachable manner such as sealing. Due to the structural defects of the blister used, several problems arise. First, according to the prior art, the inner surface of the blister is provided with a reinforcing rib. The presence of the reinforcing rib causes the reinforcing rib to interfere with the access of the packaged items (especially the slender components such as wiper blades) when accessing the packaged items, thereby affecting the user's experience. Furthermore, from the manufacturing process of the blister, the cover of the blister is coplanar with the substrate of the package. The access port of the blister of this structure needs to be formed by a punching process after the blow molding process, so that the edge of the access port produced is relatively sharp, and this sharp edge is easy to cause damage to the hands of the user who accesses the packaged items. Third, the blister according to the prior art has poor strength at the access port due to its structural design, which is not conducive to accessing the packaged items, so it is necessary to design a reinforcing rib separately to ensure its structural strength. The addition of this reinforcing rib increases the design complexity and manufacturing cost of the mold required in the blister manufacturing process. Fourthly, the design structure of the access port of the blister according to the prior art results in a more complicated structure of the cover, which also increases the design complexity of the required module and its manufacturing cost.

[0003] Therefore, there is a need for a packaging component that can be opened and closed repeatedly and has a relatively simple structure, a simple manufacturing process, and is safer for users to use. Utility Model Content

[0004] The utility model achieves the above-mentioned purpose by providing a repeatedly openable and closable package for slender components. The repeatedly openable and closable package for slender components according to the utility model comprises: an integrally formed preform, the preform comprising two side walls, a top wall, an end wall and a cover portion opposite to the end wall; a substrate, the substrate being configured to be arranged opposite to the top wall and being non-detachably attached to the two side walls and the end wall of the preform to define the storage space of the blister package together with the preform. The cover portion is configured to be able to repeatedly open and close the access port leading to the storage space defined by the preform and the substrate, and when the cover portion is in an open state to expose the access port, the cover portion has a position that makes at least a portion of the cover portion coplanar with the top wall.

[0005] According to one embodiment of the utility model, the cover portion includes: a first folding portion, the first folding portion is provided with a first proximal side connected to the top wall and a first distal side away from the top wall, and is provided with a first joining portion; a second folding portion, the second folding portion is provided with a second proximal side connected to the first distal side of the first folding portion and a second distal side away from the first distal side, and is provided with a second joining portion, the second joining portion is configured to be able to engage with the first joining portion, so as to keep the first folding portion and the second folding portion in a state of overlapping each other; and a shielding portion, the shielding portion is provided with a shielding portion proximal side connected to the second distal side of the second folding portion and a shielding portion distal side away from the second distal side, and the shielding portion is configured to be able to close the access port when the first folding portion and the second folding portion are overlapped with each other.

[0006] Further, a width of the top wall between the two side walls is not greater than a width of the shielding portion near the shielding portion, and a width of the substrate between the two side walls is not greater than a width of the shielding portion far from the shielding portion.

[0007] Furthermore, at least one of the width of the first distal side of the first folding portion, the width of the second proximal side of the second folding portion, the width of the second distal side of the second folding portion and the width of the proximal side of the shielding portion is not equal to the remaining widths.

[0008] According to another embodiment of the utility model, the shielding portion is provided with a side wall engaging portion for engaging with the two side walls so as to keep the shielding portion against an engaging side surface of each of the two side walls opposite to the end wall.

[0009] Furthermore, a cover joint portion is provided on the joint side surface of each of the two side walls for jointing with a corresponding side wall joint portion on the shielding portion.

[0010] Furthermore, the joining side surface of each of the two side walls is perpendicular to the top wall, or inclined at the same angle relative to the top wall, and the cover joining portion is an extension extending perpendicularly from a corresponding one of the joining side surfaces; and / or the joining side surface of each of the two side walls is in the form of a flange flipped from the corresponding side wall toward the outside of the blister package.

[0011] Still further, the cover engaging portion is in the form of a recessed portion extending away from the cover relative to the corresponding engaging side surface, or in the form of a convex portion extending toward the cover relative to the corresponding engaging side surface.

[0012] According to a third embodiment of the present invention, both the first engaging portion and the second engaging portion are through holes extending through the thickness of the cover portion, and are configured to be able to serve as suspension openings for receiving the suspension after being engaged with each other.

[0013] The repeatedly openable and closable packaging piece for the slender member according to the utility model has a relatively simple structure and does not require a punching process, thereby resulting in a simple manufacturing process, low manufacturing cost, and safer use for users.

[0019] Figure 6 and Figure 7 They are shown respectively Figure 5 Several alternative structures of the structure encircled in circle C in FIG. DETAILED DESCRIPTION

[0020] The following description will be made in conjunction with the accompanying drawings. In the accompanying drawings, similar elements are intended to refer to similar structures.

[0021] Figure 1Shown is a partial top view stereogram of a blister according to the prior art. As can be seen in the figure, a reinforcing rib 801 protruding inwards is provided on the inner surface of the side wall of the blister 800 according to the prior art. Although only one reinforcing rib 801 is visible in the figure, it is known to those skilled in the art that the reinforcing rib 801 should be spread over the side wall of the blister 800 in an interval manner. The existence of these reinforcing ribs 801 more or less affects the access of packaged articles (not shown) such as wiper parts. For example, when intending to take out the packaged articles, the reinforcing rib 801 may be blocked, causing trouble for the user (user).

[0022] As described in the background technology section, the access opening 802 is formed by punching after the preform is formed by blow molding or the like, so not only is the edge of the access opening 802 sharp, but the strength of the access opening 802 (especially at the junction edge 805 with the cover 804) is weak due to the thin material thickness of the blister 800. Therefore, Figure 1 The blister 800 shown in FIG. 8 has its strength enhanced by providing a reinforcing rib 803. The reinforcing rib 803 is in the form of a convex portion extending from the junction edge 805 toward the cover portion 804 and protruding upward from the cover portion 804.

[0023] The cover 804 is configured so that when it is in an open state, a portion of the cover 804 can be in a position that is substantially coplanar with a substrate (not shown in the figure). The substrate is configured to be attached to the blister 800 in a manner such as sealing to define a storage space for storing packaged items together with the blister 800. The substrate can be made of materials such as cardboard, plastic sheets, aluminum foil or composite materials thereof. The structure in which a portion of the cover 804 is configured to be coplanar with the substrate determines that after the preform is blown to form the preform, it is necessary to apply an additional separate process such as punching to the preform to form an access port.

[0024] The cover 804 includes a first folding portion 8041 and a second folding portion 8042 which are connected to each other and can be overlapped with each other. The first folding portion 8041 is provided with a reinforcing rib 803 and shares a joint edge 805 with the access port 802. The second folding portion 8042 is provided with a joint portion 8043 which is engaged with the reinforcing rib 803 in a folded state (i.e., the cover 804 is in a closed state of closing the access port 802) and a protrusion 8044 which is engaged with the access port 802. In the folded (closed) state, the joint portion 8043 can receive the reinforcing rib 803, and the protrusion 8044 can extend into the access port 802, thereby helping to keep the cover 804 closed to the access port 802.

[0025] It can be seen that the structure of the cover 804 is relatively complex, which directly determines that the design complexity of the mold required in its blow molding manufacturing process is relatively high, which inevitably increases the manufacturing cost of the blister 800 in the prior art.

[0026] Figure 2A and Figure 2B A top perspective view and a bottom perspective view are shown, respectively, of a blister having an alternative structure according to the prior art. Figure 2A and Figure 2B The structure of the blister shown is similar to Figure 1 The main difference of the structure shown is that the reinforcing rib 801' on the side wall of the bubble cap 800' is changed from protruding inward to protruding outward, which effectively solves the problem of access obstruction. However, in order to further facilitate access and reduce the risk of injury during access, the bubble cap 800' has a larger size of the access port 802' than the bubble cap 800, thereby further reducing the strength of the junction 805' between the access port 802' and the cover 804'. For this reason, the bubble cap 800' newly adds an auxiliary reinforcing rib 803' on the outer side of the reinforcing rib 803, which results in the need to change the structure of the joint 8043' on the cover 804' that is engaged with the reinforcing rib accordingly, which further increases the structural complexity of the cover 804', thereby aggravating the design complexity of the required mold. In addition, since this structural improvement still needs to form the access port 802' through a punching process, there is still a risk of easy injury to the user due to the sharp edge of the access port.

[0027] In order to solve the above problems, a blister package for a slender member that can be opened and closed repeatedly is proposed according to the utility model, which will be described below in conjunction with the accompanying drawings.

[0028] Figure 3 , Figure 4 and Figure 5 They are respectively a top perspective view, a bottom perspective view and a top view of the repeatedly openable and closable blister package for elongated members according to the present invention.

[0029] The blister package according to the present invention comprises a blister 100 and a substrate attached to the blister 100 by means such as sealing. The commonly used substrate is omitted in the figure. The blister 100 comprises two side walls 101, a top wall 102, an end wall 103 and a cover 104 opposite to the end wall 103, which are usually integrally formed by a process such as blow molding. Although the blister 100 is described herein as being integrally formed, the blister can also be made by independent molding, for example, by separately molding the cover and other parts and then assembling them together. Figure 3-5As shown in FIG. 1 , no structure is provided on the side wall 101 and the top wall 102 that may block the access of the packaged articles (not shown). Of course, as known to those skilled in the art, the side wall 101 of the blister 100 may also be as shown in FIG. Figure 2A and Figure 2B As shown in , outwardly protruding reinforcing ribs are provided. Equally, a small protrusion can be provided on the top wall 102 to serve as a stopper for decoration or information inserts.

[0030] The blister package is defined by the blister 100 and the substrate (not shown) on the side opposite to the end wall 103 with an access opening 105, see Figure 4 When the cover 104 is in the open (unfolded) state, the access opening 105 is exposed, and at least a portion of the cover 104 can be coplanar with the top wall 102, thereby allowing the user to access the packaged items through the access opening 105. In other words, at this time, the cover 104 has (can be in) a position (state) in which a portion of it is coplanar with the top wall 102. When the cover 104 is in the closed (folded) state, at least a portion of the cover 104 can cover the access opening 105 and maintain the covering state.

[0031] It can be seen that the access port 105 is formed by forming a preform by, for example, a blow molding process, and then the substrate is sealed to the preform, so the edge of the access port 105 is not sharp, reducing the potential risk of injury to the user. In addition, since a portion of the cover 104 is configured to be coplanar with the top wall 102, this positioning setting determines that no additional punching process is required to form the access port, because the formation of the access port is sufficient to be achieved between the preform and the substrate through the combination of the blow molding process and the sealing process. Obviously, this manufacturing process reduces the punching process required for forming the access port in the existing manufacturing process, thereby reducing the manufacturing cost.

[0032] The side surface 1011 of the side wall 101 of the blister 100 adjacent to the cover portion 104 may be in the form of a flange turned outward from the corresponding side surface, such as Figure 3 and Figure 4 As shown. However, in the case where the side wall 102 has a sufficient thickness, the side surface 1011 may also be in the form of a surface that can reflect the thickness. The side surface 1011 may be arranged perpendicular to the top wall 102, or may be inclined relative to the top wall 102. For example, the side surface 1011 may be inclined toward the cover 104 or away from the cover 104. However, the angles of the corresponding side surfaces 1011 of the two side walls 101 relative to the top wall 102 are equal. A cover joint portion 1012 is provided on the side surface 1011 for cooperating with a side wall joint portion (described in detail below) on the cover 104. As shown Figure 4As shown in , the cover engaging portion 1012 may be in the form of a recess extending from the side 1011 and perpendicularly to the side 1011 away from the cover 104. Alternatively, the cover engaging portion may be in the form of a convex portion extending from the side 1011 and perpendicularly to the side 1011 toward the cover 104.

[0033] The cover portion 104 of the blister 100 includes a first folding portion 1041, a second folding portion 1042 and a shielding portion 1043 connected in sequence. Figure 5 As clearly indicated in FIG. 1 , the first folding portion 1041 has a first proximal side 1041P connected to the top wall 102 and a first distal side 1041D away from the top wall 102, and is provided with a first joint portion 1041E (indicated in FIG. Figure 4 The second folding portion 1042 has a second proximal side 1042P connected to the first distal side 1041D of the first folding portion 1041 and a second distal side 1042D away from the first distal side 1041D, and is provided with a second joint portion 1042E (marked at Figure 4 The shielding portion 1043 has a shielding portion proximal side 1043P connected to the second distal side 1042D of the second folding portion 1042 and a shielding portion distal side 1043D away from the second distal side 1042D.

[0034] When the blister package is in the closed state, the cover portion 104 is in the folded state. At this time, the second folded portion 1042 and the first folded portion 1041 overlap each other, and the first engaging portion 1041E can engage with the second engaging portion 1042E and maintain this engagement state by means such as shape matching. Figure 3-5 The specific forms of the first joint part 1041E and the second joint part 1042E are shown in FIG, but the present invention is not limited thereto. In other words, those skilled in the art can conceive of changing the parameters such as the shape and quantity of the two joint parts as needed, as long as the two can achieve mutual engagement and maintain this state.

[0035] In addition, Figure 3-5 , the first joint portion 1041E and the second joint portion 1042E are shown as a blind hole in the form of one convex and one concave, the depth of the blind hole is not less than 5 mm, and through holes 1041H and 1042H are respectively provided on the first folding portion 1041 and the second folding portion 1042. The two through holes can be aligned with each other when the cover portion 104 is in a folded state, thereby serving as a hanging opening (hole) for receiving a hanger to facilitate displaying the blister package. Alternatively, the through hole can be combined with the joint portion, that is, only the joint portion in the form of a through hole is provided on the two folding portions 1041 and 1042, as shown in FIG. Figure 7As shown in , the engagement portion on only one folding portion has an engagement structure of a certain depth. In this way, the structure can have an engagement function and can also be used as a hanging hole after the folding engagement.

[0036] like Figure 3 and Figure 4 As shown in the figure, when the cover 104 is in the open (unfolded) state, at least the first folding portion 1041 and the second folding portion 1042 can be coplanar with the top wall 102. Although the shielding portion 1043 is shown as not coplanar with the rest of the cover 104, the present invention is not intended to be limited thereto.

[0037] The shielding portion 1043 is provided with a side wall joint portion 1043E in the form of a convex portion or a concave portion extending from the side of the shielding portion 1043 facing the access opening 1012 toward or away from the access opening 1012. The side wall joint portion 1043E is configured to engage with the cover joint portion 1012 on the side 1011 of the side wall 102 and maintain the engagement state when the cover 104 is in a folded state so that the shielding portion 1043 shields the access opening 105, thereby maintaining the state in which the cover 104 (the shielding portion 1043) shields the access opening 1015, thereby achieving the closure of the blister package.

[0038] Figure 6 and Figure 7 Shows Figure 5 An alternative structure to the structure shown in circle C in . It is intended to indicate that the width of the side of the top wall 102 away from the end wall 103 (the distance between the two side walls 101) is not greater than the width of the shielding portion proximal side 1043P of the shielding portion 1043 (the dimension in the direction perpendicular to the side walls 101), and the width of the substrate between the two side walls 1012 is not greater than the width of the shielding portion distal side 1043D of the shielding portion 1043, so that the shielding portion 1043 can (by itself) shield the access port 1015. The width of the first distal side 1041D of the first folding portion 1041, the width of the second proximal side 1042P of the second folding portion 1042, the width of the second distal side 1042D of the second folding portion 1042, and the width of the shielding portion proximal side 1043P of the shielding portion 1043 may be different, or at least one of them may be different from the remaining widths. Although Figure 6 and Figure 7 Only some examples of the relationship between the above widths are shown, but those skilled in the art can envision many variations of the width relationship.

[0039] Although multiple embodiments of the utility model have been described with reference to the accompanying drawings, as will be appreciated by those skilled in the art, various modifications may be made to the above embodiments without departing from the scope defined by the appended claims. The above embodiments are provided only as examples to illustrate the technical solutions of the utility model and are not intended to limit the scope of protection of the utility model. Features or elements described in one embodiment may be incorporated into another embodiment for implementation unless they conflict with existing features or elements in another embodiment.
